If he has a pediatric murmur, I'm thinking congenital. Hepatomegaly, malleolar edema and BRD, something that overloads the right heart. So we rule out aortic and mitral stenosis. A patent ductus would give cyanosis: ruled out. VSD or ASD? If I am told that he has AF, it is because the atria are of size XL, and a VSD does not produce atrial dilatation.

On follow up study, patients were investigated by echocardiography, ECG and assessed for quality of life by a questionnaire Among forty ASD type II manifested in adulthood which were referred to our department of cardiology five cases of ASD manifested in the sixth decades (2 men and 3 women). Complaints were dyspnea and palpitations in 4 cases and chest pain in only one patient. Slight anterior chest deformity was present in the older patient. Systolic murmur was found in the 3rd left intercostals space and the pulmonary second heart sound was accentuated in all patients. Complete right bundle branch block and right ventricular hypertrophy were found in all cases. Three patients presented atrial fibrillation. There was marked cardiomegaly in four patients.

Echocardiographic data revealed large secundum ASD (mean 20 mm, ranged between 10 and 30mm), severe systolic pulmonary pressure in two cases (&gt;5O mmhg). MeanQP/QS was 2.2 and contrast revealed bidirectional shunt in one patient. All patients were studied by venous cardiac catheterization. They showed a significant increase in the oxygen content of right atrial blood. Three patients underwent surgical atrial septal defect closure under general anesthesia. There were no operative or peri operative deaths. At mean follow up of 50±75 months, there was one late death from heart failure in a patient with advanced preoperative heart failure. The oldest patient is in the medical group and he is 75years old. Most survival patients remain in good clinical condition. Some of them were symptomatic at the last follow up and complained of shortness of breath on effort and palpitations in two cases. Two patients were in chronic atrial fibrillation developed during follow up. However, chest RX showed reduction in cardiothoracic ratio postoperatively. Echocardiographic examination confirmed that there was no residual shunt in across the atrial septum in any patient. Systolic pulmonary pressure felled only in 2 patients in the surgery group.

The upper chamber receives the pulmonary veins and the lower chamber contains the atrial appendage and the mitral valve. The 2 chambers communicate through a defect in the membrane. Cor triatriatum is often associated with other congenital cardiac anomalies. Most frequently, the upper chamber communicates with the right atrium through a patent foramen ovale or atrial septal defect, and the clinical symptoms simulate anomalous pulmonary venous return. Less commonly, the foramen ovale communicates with the distal chamber and the clinical features mimic mitral stenosis. When cor triatriatum is the only abnormality, the clinical findings are also similar to mitral stenosis with development of pulmonary hypertension and subsequent right ventricular hypertrophy and atrial enlargement.

And with this information, we cannot know if the stenosis is severe. Therefore, the first thing we will have to do will be to study the valve disease: we do not want to put the patient to run or overload him with dobuta and have a syncope, nor do we want to do a catheterization without having first performed another noninvasive test.

When the a priori probability is low or moderate (less than 0.5) the efficacy of EE, ECHO and SCINTI is excellent as there are few false negative results. When the a priori probability of coronary disease is high (0.7 or more), the percentage of false negative results (patients with undetected significant coronary disease) becomes very high.

The resulting molecule is often referred to as Hb A1c, a glycated hemoglobin. The binding of glucose to amino acids in the hemoglobin takes place spontaneously (without the help of an enzyme) in many proteins, and is not known to serve a useful purpose. However, as the concentration of glucose in the blood increases, the percentage of Hb A that turns into Hb A1c increases. In diabetics whose glucose usually runs high, the percent Hb A1c also runs high. Because of the slow rate of Hb A combination with glucose, the Hb A1c percentage reflects a weighted average of blood glucose levels over the lifetime of red cells, which is approximately 120 days.

We cross-tabulated 2-hour glucose concentrations on an oral glucose tolerance test separated into 4 intervals (&lt;7.8 mmol/L [140 mg/dL], 7.8-11.0 mmol/L [140-199 mg/dL], 11.1-13.3 mmol/L [200-239 mg/dL], and &gt;/=13.3 mmol/L [240 mg/dL]) with Hb A1C levels separated into 3 intervals (normal; &lt;1% above the upper limit of normal; and greater than or equal to the upper limit of normal + 1%). Approximately two thirds of patients in both data sets with 2-hour glucose concentrations of 11.1 to 13.3 mmol/L (200-239 mg/dL) had normal Hb A1C levels. In contrast, 60% to 80% of patients in both data sets with 2-hour glucose concentrations &gt;/=13.3 mmol/L (240 mg/dL) had elevated Hb A1C levels. Since Hb A1C levels are the best measures presently available that reflect long-term glycemia, we conclude that the 2-hour glucose concentration criterion on an oral glucose tolerance test for the diagnosis of diabetes should be raised from &gt;/= 11.1 mmol/L (200 mg/dL) to &gt;/= 13.3 mmol/L (240 mg/dL) to remain faithful to the concept that diagnostic concentrations of glucose should predict the subsequent development of specific diabetic complications (e.g., retinopathy)." }, { "id": "pubmed23n0810_9863", "title": "All-cause mortality in patients with type 2 diabetes in association with achieved hemoglobin A(1c), systolic blood pressure, and low-density lipoprotein cholesterol levels.", "score": 0.009523809523809525, "content": "To identify the ranges of hemoglobin A(1c) (HbA1c), systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDL-C) levels which are associated with the lowest all-cause mortality.

The patient was dialyzed for 10 days and responded to steroids and went home with an improving Cr of 3.5 mg/dL, back to baseline of 1.5 in 8 weeks. Discussion. Internists encounter patients with acute kidney injury (AKI) on a daily basis, most of which can be explained by prerenal azotemia, acute tubular necrosis (ATN), obstruction, or rhabdomyolysis among other etiologies. Cocaine is only rarely implicated as an etiology of AKI and if it is, usually the injury is due to ATN or pigment effects. Acute interstitial nephritis (AIN) caused by cocaine, on the other hand, has only been described in a handful of cases. AIN is a renal lesion that causes a decline in creatinine clearance and is characterized by an inflammatory infiltrate in the kidney interstitium and is most often associated with drug therapy. AIN can also be seen in autoimmune disorders like systemic lupus erythematosus, Sjögren's syndrome, or sarcoidosis; or with infections remote to the kidney like Legionella, leptospirosis, and streptococcal disease. Our case was very similar to the other reported cases of AIN due to cocaine in that all have occurred in middle-aged African American males and all have responded to steroids. This case reminds clinicians to consider AIN in patients with AKI and a history of cocaine abuse.

To treat the crescentic glomerulonephritis, steroid and cyclophosphamide were administered while hemodialysis was carried out simultaneously. Although P-ANCA and C-ANCA were negative, anti-GBM antibody was proven to be positive thereafter (169 U) and six sessions of plasmapheresis were additionally performed to remove the antibody. Two months after the last plasmapheresis, the reduced urine volume (300 ml/day) gradually returned to normal. Hemodialysis was terminated because the S-Cr concentration reached a plateau at 4 mg/dl. Repeated biopsy revealed marked glomerulosclerosis, hence hypertension treatment and a low protein diet were ordered.

Sixty patients (21 F/39 M) with refractory CHF (NYHA class IV) of different etiologies, unresponsive to high oral doses of furosemide, ACE-inhibitors, digitalis, and nitrates, aged 65-90 years, were enrolled. They had to have an ejection fraction (EF) &lt;35%, serum creatinine &lt;2 mg/dl, BUN &lt;/=60 mg/dl, a reduced urinary volume and a low natriuresis. The patients were randomised in two groups (single blind): group 1 (11 F/19 M) received an i.v. infusion of furosemide (500-1000 mg) plus HSS (150 ml of 1.4-4.6% NaCl) b.i.d. in 30 min. Group 2 (10 F/20 M) received an i.v. bolus of furosemide (500-1000 mg) b.i.d., without HSS, during a period lasting 6-12 days. Both groups received KCl (20-40 mEq.) i.v. to prevent hypokalemia. All patients underwent at entry a physical examination, measurement of body weight (BW), blood pressure (BP), heart rate (HR), evaluation of signs of CHF, and controls of serum Na, K, Cl, bicarbonate, albumin, uric acid, creatinine, urea and glycemia and daily during hospitalization, as well as the daily output of urine for, Na, K and Cl measurements. Chest X-ray, ECG and echocardiogram were obtained at entry during and at the discharge. During the treatment and after discharge the daily dietary Na intake was 120 mmol with a drink fluid intake of 1000 ml daily.

Pure membranous nephropathy (MN)-like glomerular lesions are rare manifestations of C3GN. Anti-neutrophil cytoplasmic antibodies (ANCAs) are also seldomly reported to be positive in C3GN. Herein, we report the case of a C3GN patient presenting with an MN-like glomerular pattern with ANCA positivity.

An 11-year-old girl showed proteinuria on a school urinalysis screening and presented with upper eyelid edema. The urinalysis showed elevated urinary protein levels and hematuria. Laboratory examinations revealed the following: serum albumin, 1.3 g/dL; serum creatinine, 0.54 mg/dL; and C3c, 67 mg/dL (normal range: 73-138 mg/dL). The physical and laboratory findings did not suggest autoimmune diseases. A renal biopsy was then performed. Specimen examination under a light microscope showed mesangial cell proliferation, increased mesangial matrix with lobulation, and some double contours of the glomerular basement membrane in almost all glomeruli, which are characteristic findings of MPGN. Immunofluorescent studies showed IgA deposits not only in the mesangial regions but also along the capillary walls, which were more strongly stained than C3. IgA subclass staining showed a stronger immunoreactivity for IgA2 than IgA1. Electron microscopic studies showed electron-dense deposits in the subendothelial, subepithelial, and paramesangial regions. Based on these findings, the patient was diagnosed with IgA-dominant MPGN. Accordingly, she was treated with three courses of methylprednisolone pulse therapy (MPT), followed by prednisolone, mizoribine, and lisinopril. Although hypocomplementemia improved after three courses of MPT, nephrotic-range proteinuria and hypoalbuminemia remained; therefore, two courses of MPT were additionally administered, and the immunosuppressant was changed from mizoribine to cyclosporine (CsA). Finally, the urinary protein level decreased, and a subsequent renal biopsy, two years later, showed improvement in the lesions. We report an atypical case of MPGN with IgA2 dominant deposits along the glomerular capillary wall and in the mesangial region. The case was refractory to standard therapy but sensitive to CsA, which resulted in remission.

During this time, 3,810 kidney biopsies were performed, of which 89.3% were from native (n=3,446) and 10.7% from transplant kidneys. Throughout this period, 5% of renal biopsies were not diagnostic, so in this paper we report data regarding 3,269 native kidney nephropathies. During the years 1977 through 2005, data for renal biopsies were collected on specific registers filled out by clinicians. Information collected in the database included a variety of indicators, such as clinical anamnesis, creatinine clearance, daily proteinuria, hemoglobin levels, blood pressure, height and weight, clinical presentation, and current medications. Clinical presentation was defined as urinary abnormalities (UA), nephrotic syndrome (NS) and acute nephritic syndrome (ANS). Renal diseases were divided into 4 major categories: primary glomerulonephritis (GN), secondary GN, tubulointerstitial nephropathies (TIN) and vascular nephropathies (VN).

Serum CRP, albumin, uric acid levels, 24 hour urine protein presence, leucocyte count, C3, C4, IgG, IgA and IgM levels were assessed. The most common diagnosis of glomerulonephritis was IgAN with the percentage of 29.7% within the groups. Male gender was predominant except lupus group. Only the ones with crescentic glomerulonephritis had higher CRP levels. In 20% of patients with IgAN, in 8.3% of the ones with MN, in 35% of crescentic group, in 42% of FSGS group, in 30% of patients with MPGN and in 33% of the ones with lupus nephritis uric acid levels were found as elevated. In IgAN, FSGS and lupus nephritis normoalbuminemia and nephritic proteinuria, in MN and crescentic glomerulonephritis hypoalbuminemia, nephrotic proteinuria, in MPGN hypoalbuminemia, nephritic proteinuria were established. Serum Ig G levels were lower in MN and MPGN. Serum IgA levels were found as elevated in IgAN. Serum C4 levels were found as lower in lupus nephritis and MPGN. In patients admitted in clinical picture of glomerulopathy, since measurements of serum CRP, albumin, uric acid, C3, C4,IgG, IgA, IgM levels, leucocyte count and 24 hour urine protein amount can lead to predict the histopathological diagnosis, their significance in routine investigations has been suggested also in our study." }, { "id": "pubmed23n0392_19300", "title": "Aristolochic acid-induced Fanconi's syndrome and nephropathy presenting as hypokalemic paralysis.", "score": 0.008849557522123894, "content": "Hypokalemic paralysis rarely is seen as the presenting feature in patients with Fanconi's syndrome.

This condition presents with crescentic glomerulonephritis with little or no immunoglobulin staining and negative serological workup aside from a positive antineutrophil cytoplasmic autoantibody (ANCA). Typically, patients with pauci-immune CrGN have an underlying systemic small vessel vasculitis, but in rare cases, it presents without any known vasculitis or ANCA. Pauci-immune ANCA negative CrGN is often strictly isolated to the kidneys. In this case, we present a patient with ANCA negative, pauci-immune CrGN with severe diffuse alveolar hemorrhage. A 66-year-old Hispanic woman with a past medical history of controlled hypertension presented with fatigue and dysphagia. On admission, her vital signs were significant for hypoxia on room air, and her physical exam was remarkable for crackles bilaterally. The initial laboratory results revealed anemia (hemoglobin 5.2 g/dL), hyperkalemia (6.3 mmol/L), elevated creatinine (4.50 mg/dL, with a baseline of 0.9mg/dL). Urinalysis showed moderate blood and urine protein (200 mg/dL). Urine microscopic examination showed 25-50 RBCs seen/high power field. The patient was admitted to ICU due to hypoxia, a computed tomography scan of the chest/abdomen/pelvis was obtained and revealed multifocal pulmonary consolidations. A blood transfusion was ordered. The patient began to have hemoptysis and subsequent bronchoscopy showed diffuse alveolar hemorrhage. ICU team proceeded to intubate her as the hemorrhage continued to worsen. Further workup revealed a positive anti-nuclear antibodies (ANA) of 1:40, but otherwise negative serologies including myeloperoxidase (MPO)-ANCA, glomerular basement membrane antibody, and anti-double stranded DNA. Kidney biopsy showed necrotizing glomerulonephritis with crescents and negative immunofluorescence. She was diagnosed with pauci-immune ANCA-negative vasculitis with associated diffuse alveolar hemorrhage and nephritis based on these results and was started on pulse-dose steroids. The patient was started on intravenous (IV) high-dose cyclophosphamide, which helped improved the overall clinical condition significantly. After creatinine began trending down and urine output improved, the patient was discharged on a regimen of daily oral cyclophosphamide and steroid taper. Patient oxygen requirements decreased and she was sent home with supplemental oxygen while requiring 3L/min of oxygen. Pauci-immune and ANCA-negative glomerulonephritis with concurrent diffuse alveolar hemorrhage is exceptionally rare. In this situation, medical management relied on clinical evidence from similar populations in the use of steroids and cyclophosphamide. This case report aims to shed more light on the clinical progression and management of this condition.

This question combines several important facts. To begin with, this is a patient with an extensive anterior and lateral AMI, with cardiogenic shock. On the other hand, in the history, we are told that the patient had a stroke 4 months ago. It is evident from the patient's clinical picture that an urgent reperfusion strategy is indicated, which invalidates options 4 and 5. The basic question is whether to choose fibrinolysis (which can be done in a regional hospital) or PCI (for which the patient should be referred to a tertiary center). Option 2 does not make much sense, since in the event that fibrinolysis is indicated, it would only be a waste of time to make the transfer. A history of stroke (presumably ischemic) 4 months ago is a relative contraindication for fibrinolysis (if the time is less than 3 months it is an absolute contraindication), but the definitive factor that tips the balance towards PCI is the extent of AMI and the presence of shock, which are indications for urgent PCI. Therefore, the correct answer is 3.

To evaluate in-hospital mortality of the patients admitted to our institution for Q wave AMI presented in CS. Between 05/93 and 05/03, 30 consecutive pts, 26 men and 4 women, in CS following AMI were treated with direct PTCA, 26 without thrombolysis and 4 as rescue after failed streptokinase. AMI was defined by prolonged chest pain and &gt; or =1 mm ST segment elevation in &gt; or =2 contiguous peripheral leads or &gt; or =2 mm for precordial leads on the admission ECG. The diagnosis of CS was based on the combination of systolic blood pressure of &lt;90 mm Hg, unresponsive to volume expansion, signs of acute circulatory failure (cyanosis, cold extremities, restlessness, mental confusion or coma) and congestive heart failure secondary to myocardial dysfunction. In 40% of cases the diagnosis of CS was only clinical and in 60% of cases was confirmed by a Swan Ganz catheter. Mean age was 62.3 +/- 12.3 years, 7 had triple vessel disease, 14 a double vessel disease, 8 a single vessel disease and in one case a left main disease. The AMI was anterior in 22 pts (73%), inferior in 8 (27%).

Mean time of revascularization for the surviving was 190 +/- 329 min, and for the dead 295 +/- 212 min. Hospital mortality for inferior infarction is 12.5% after successful angioplasty.

If the involved department has adequate experience the success rate of the procedure is high and the immediate and long-term results are better than those of thrombolysis. Moreover contrary to thrombolytic treatment successful percutaneous coronary intervention in AIM is more beneficial for patients also later than 6 hours after the development of infarction pain. In the Cardiocentre of the General Faculty Hospital (GFH) patients with AIM are constantly attended, i.e. those indicated for reperfusion therapy are treated solely by the d-PTCA method. Retrospective analysis of d-PTCA in AIM made during the annual period from Jan. 1 2000 to Dec. 31 2000. Into the observation study patients were included with clinical and/or ECG signs of AIM when the period from the onset of pain to the beginning of intervention did not exceed 12 hours. All patients were given before the procedures 500 mg of acetylsalicylic acid and 10,000 u. heparin. Cardiac catheterization was implemented by the percutaneous Seldinger technique via the a. femoralis l.dx., in exceptional cases from the left femoral artery. An approach via the a. radialis and/or a. brachialis was not used in any of the patients. From the investigation patients were excluded who had before the percutaneous coronary intervention (PCI) a thrombolytic preparation (so-called rescue-PTCA). During the mentioned period in the Cardiocentre of the GFH a total of 673 PTCA were performed, incl. 127 (18.9%) d-PTCA in patients with AIM. In the mentioned group of 127 patients subjected to intervention were 87 (68.5%) men and 40 (31.5%) women. The mean age of the men was 59.1 +/- 12 years and the mean age of the women 68.2 +/- 12 years. As to the main risk factors of coronary atherosclerosis arterial hypertension was present in 48%, smoking in 42%, diabetes in 23% and hyperlipoproteinaemia in 31% of the treated patients. More than one third of the patients had a history of myocardial infarction (38%). The infarcted artery was the r. interventricularis anterior (LAD) in 51 (40.2%), the right coronary artery (RCA) in 54 (42.5%), the r. circumflex (LCX) in 16 (12.6%), the left main coronary artery in 2 (1.6%) and the bypass in 4 (3.1%). Multiple coronary affections were recorded in 80 (63%) patients, affections of one artery in 47 (37%). Primary procedural success (flow TIMI 3/2) was achieved in 121 patients (95.3%). Normal flow through the infarcted artery TIMI 3 was achieved in 118/127 (85.8%) patients. In 91 (71.7%) into the infarcted artery a coronary stent was implanted, during hospitalization no subacute stenosis of the stent developed. The mean period between the onset of infarction pain--injection was 4.4 +/- 2.3 hours. The mean period of the entire procedures was 48 +/- 14.5 minutes. As contrast material only non-ionic contrast substances were used (Iomeron 350) with a mean consumption of 150 ml per patient. The mean skiascopic time was 13.6 +/- 1.8 min. A total of 9 (7.1%) patients were treated with GP IIb/IIIa receptor blockers (abciximab). The total hospitalization mortality of the intervened group was 7.1% (9 patients). In a sub-group of 9 patients who at the onset of the procedure were in cardiogenic shock 3 (33%) died. The hospitalization mortality of the sub-group of patients with AIM without cardiogenic shock, treated with d-PTCA was 5.1% (6/118). During hospitalization the authors did not observe any intracranial haemorrhage. The group of subjects with AIM subjected to catheterization who are treated by d-PTCA is relatively numerous in our department. According to a number of clinical studies successful d-PTCA in AIM gives better short-term and long-term results as compared with thrombolytic therapy. The primary success rate of d-PTCA was high and the hospital mortality was low and comparable with contemporary data in the literature. Direct PTCA is effective treatment in patients with acute myocardial infarction. The authors results confirm the high procedural success rate and acceptable hospital mortality. These favourable results of an invasive approach to treatment of AIM must be compared in future with bolus thrombolytic treatment by new types of thrombolytic preparations in combination with anti-platelet treatment with blockers of platelet glycoprotein receptors IIb/IIIa with/or without subsequent percutaneous coronary intervention." }, { "id": "pubmed23n0592_21267", "title": "Immediate angioplasty versus standard therapy with rescue angioplasty after thrombolysis in the Combined Abciximab REteplase Stent Study in Acute Myocardial Infarction (CARESS-in-AMI): an open, prospective, randomised, multicentre trial.", "score": 0.0134975035965135, "content": "Thrombolysis remains the treatment of choice in ST-segment elevation myocardial infarction (STEMI) when primary percutaneous coronary intervention (PCI) cannot be done within 90 min.

Intravenous administration of abciximab can restore a normal flow in the infarcted related coronary artery (IRA) after few minutes.

Between April 1997 and January 1998, 38 AMI were treated with abciximab in pre-hospital phase (group A). Mobil Intensive Care Unit (MICU) team implemented the treatment and guaranteed immediate transport to the cathlab (abciximab bolus-coronary angiography time = 37 +/- 17 min). Immediate results were compared to those of 198 paired patients who were treated for AMI during the same period (Group T). Initial IRA flow TIMI grade 3 was significantly higher in group A, 24%, than in group T, 9% (p &lt; 0.017). The rates of per-procedural complications (no flow, distal embolism), of local complications, of transfusions were not significantly different. During 1 month follow-up, there was no significant difference between group A and group T concerning death, re-MI, stent thrombosis and new revascularization. To conclude, the pre-hospital treatment with abciximab in AMI is feasible by MICU medical team without any delay of the cathlab admission. It is associated with no increased hemorrhagic complications rate. The abciximab pre-hospital treatment improves the initial IRA patency.

The rarity and limited knowledge of the disease make its management challenging. Prompt diagnosis of the condition is extremely important to decrease both long- and short-term complications. Treatment options depend on hemodynamic stability and the location of the dissection- with more distal lesions treated more conservatively as opposed to proximal lesions which are treated with percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). The following are the two cases with different presentation, management and outcomes. Our first patient was a 35-year-old woman with no medical history who presented with acute, anginal pain, diaphoresis and palpitations. She was hemodynamically stable on presentation, with work-up significant for electrocardiogram (ECG) with sinus bradycardia, ST elevation in leads V1-V6, and elevated troponin level of 4 ng/ml. There was no evidence of a pulmonary embolism on computed tomography (CT) of the chest. A coronary angiogram showed 100% dissection of the proximal to mid-left anterior descending (LAD) artery. Attempts to place a stent in the proximal to mid LAD were unsuccessful as the true lumen of the LAD was not accessible. The patient became hemodynamically unstable, and an emergent CABG was done, restoring blood flow. The patient recovered during her hospital stay and was discharged with dual antiplatelet therapy (DAPT), beta-blockers, and atorvastatin. The second patient was a 28-year-old woman, with a history of hypertension who presented with anginal chest pain. Workup showed ECG with minimal ST elevations in anteroseptal leads, with elevated troponin level to 0.71 ng/ml. Coronary angiogram showed 40-50% stenosis of the mid LAD with an aneurysmal segment. An echocardiogram showed no evidence of wall motion abnormalities, and she had a normal left ventricular ejection fraction (LVEF). She was discharged home the next day, on medical management. After two days, she returned to the hospital with similar complaints, with work-up significant for ECG with non-specific ST-T abnormality, and troponin level which peaked at 2.22 ng/ml. She was started on a heparin drip, and a repeat left heart catheterization revealed type 2 dissection of the mid to distal LAD, with intravascular ultrasound showing a fractional flow reserve of 0.76. She was discharged home on DAPT, beta-blocker, calcium channel blocker (CCB), and atorvastatin, with close cardiology follow up. These two cases highlight the importance of keeping in mind the possibility of SCAD, especially when relatively healthy young women present with anginal symptoms.

Upon deciding about whether or not to use fibrinolysis, it should preferably occur within the first 30 minutes of the first medical contact. This strategy can be achieved either as prehospital fibrinolysis by the emergency medical service (EMS) provider or within 30 minutes of arriving at a non-PCI capable facility (door to needle time). Contraindications to fibrinolysis require prompt review if this strategy is an option. Absolute contraindications are any previous intracranial hemorrhage, ischemic stroke in the past 3 months, central nervous system neoplasm or arteriovenous malformation, major head trauma or surgery within the past month, known active bleeding or bleeding diathesis (with the exception of menses), suspected aortic dissection, severe uncontrolled hypertension unresponsive to emergent medical therapy and use of streptokinase in the last 6 months.

[13] Patients with developed collateral circulation may have more significant benefits beyond the 2-hour timeframe when compared to patients without collateral circulation. The CAPTIM trial compared prehospital fibrinolysis with PCI in patients with STEMI and found that patients who received treatment with pre-hospital fibrinolysis within 2 hours of symptoms onset had better survival when compared to PCI strategy. [14] Based on the STREAM trial, prehospital fibrinolysis provides similar efficacy when compared to PCI in patients with STEMI who presented within 3 hours and were unable to get PCI within 1 hour but with a higher rate of intracranial bleeding. [15] [16] An overview of nine randomized trials published by the Fibrinolytic Therapy Trialist collaborative group suggests that characteristics of patients who derive the least benefit from fibrinolysis are those with a delayed presentation (over 13 to 24 hours of symptom onset), elderly (age greater than 75 years), inferior ST elevations, and uncontrolled hypertension (systolic blood pressure (BP) more than 175 mmHg). [17] Thus, as a general framework, it seems that patients who present with early onset of symptoms but with a significant anticipated delay in transportation to a PCI-capable facility should get fibrinolytic treatment in the absence of absolute contraindications. While on the other hand, patients who present with onset of symptoms longer than 12 hours and absence of hemodynamic instability and evidence of ongoing ischemia of a large amount of myocardium should not receive fibrinolysis due to a likely lack of significant benefit. Other cases require evaluation on a case-by-case basis with careful consideration of risks and benefits. Upon deciding for a fibrinolytic strategy, agents that are fibrin-specific and given as a bolus (such as tenecteplase and reteplase) are preferred to other agents due to demonstrated lower risk of intracerebral bleeding and are more convenient to use.

Myocardial injury or infarction in the setting of an anaphylaxis can be due the anaphylaxis itself, when it is known as Kounis syndrome or it can also be due to the effect of epinephrine treatment. Epinephrine is considered as the cornerstone in management of anaphylaxis. Myocardial infarction secondary to therapeutic doses of adrenaline is a rare occurrence and only a few cases have been reported in literature. The mechanism of myocardial injury was considered to be due to coronary vasospasm secondary to epinephrine as the coronary angiograms were normal on these occasions. A 21-year- old previously healthy male got admitted to the local hospital with an urticarial rash and difficulty in breathing, one hour after ingestion of prawns for which he was known to be allergic. He was treated with 0.5 ml of intramuscular adrenaline (1:1000) which was administered to the lateral side of the thigh, following which he developed palpitations and tightening type central chest pain. Electrocardiogram showed ST segment depressions in leads III, aVF and V1 to V5 and he was transferred to a tertiary care hospital. The second electrocardiogram, done 2 h later, showed resolution of ST segment depressions but new T inversions in leads I and aVL. Troponin I was elevated with a titer of 2.15 ng/ml.

Little to comment.... is the definition of delirium. Altered state of consciousness.
A 79-year-old patient is brought to the ED at 7 pm from a nursing home, but we do not have the referral report and therefore do not know his history. He is disoriented in time and space. He has trouble remembering simple information. Sometimes he becomes very nervous and agitated, because he sees threatening people, even when he is alone. At other times he appears drowsy and inattentive. The main data supporting the diagnosis of delirium as opposed to dementia is:

Intracerebral localization is relatively rare, its impact is 1 to 5% of all cases of hydatidose. This localization is the child's appendage with a masculine predominance. The cyst hydatic intracranien is often lone, of localization usually supratentorielle, sometimes infratentorielle. Symptoms are especially the diffuse headache associated to various neurological signs in relation with sits of the tumor. The psychiatrics symptoms depends on its localization, sides, intracranial hypertension, and the previous personality. In 15 to 20% of cases these tumors can appear in the beginning of their evolution by the isolated psychiatric symptoms. We report the case of two patients that have been hospitalized first in the Academic Psychiatric Unit of Marrakech for isolates psychiatric disorders and whose scanning revealed the presence of cerebral hydatic cyst and that required a surgical intervention in neurosurgery. Case 1 - Patient 29 years old, bachelor, uneducated, leaving in country outside, fermar, in permanent contact with dogs. No particular medical history. The patient has been brought by his family to the psychiatric emergencies after behavior disorders. The beginning of his symptomatology was one year ago by behavior disorders: instability, violence, isolation, and a corporo-sartorial carelessness. His symptomatology worsened and the patient became very aggressive. In psychiatric unit, he was disregarded, sad, anguished, indifferent to his state, very dissonant, completely detached, depersonalized. He brought back some visual and auditory hallucinations with attitude of monitoring. He was raving with delirium of persecution, of ideas of reference and delirium of bewithment. He was unconscious of his disorders. The patient has first been put under classical neuroleptic 9 mg/day of Haloperidol and 200 mg/day of chlorpromazine. The diagnosis of schizophrenia has been kept according to criteria of DSM IV. The PANSS (Positive and Negative Syndrome Scale) was to 137 (score on a positive scale was to 34, score on a negative scale was to 35 and the general psychopathologie scale was to 58). One week after his hospitalization, he developed headache with subconfusion, a cerebral scanning has been made in emergency and showed a voluminous cyst in oval foramen compressing the mesencephalon strongly. The cyst was well limited, hypodense, not taking the contrast, and without intracerebral oedema, the diagnosis of cerebral hydatic cyst has been made. The complementary exploration didn't show any other localizations, and biologic exam results didn't show any particular anomalies. The patient has been operated in neurosurgery. The immediate evolution was favorable with disappearance of confusion and absence of complications. The patient was lost of view. Six months after, the patient has been readmitted to the psychiatric emergency. He dropped his neuroleptic treatment. He was aggressive, raving, hallucinated and depersonalized. The global score to the PANSS was 63. He has been put back under neuroleptics. Three weeks after improvement and passage of the PANSS to 30, the patient went out. We couldn't have a cerebral scanner of control because the patient had no medical assurance and no money for cerebral scanner. Case 2 - Patient aged of 53 years, father of four children, uneducated, native and resident of Marrakech, confectioner as profession. He is in contact with dogs since 12 years. He has been brought to the psychiatric emergencies by his family after an agitation. The history of his illness seemed to go back at eight months ago, by the progressive apparition of an instability, sleep disorders, hostility, associated with an emotional lability. To the interview he was agitated and had a delirium of persecution. He was convinced that his wife and his children plotted against him. He had sad mood. He was anguished and had auditory and visual hallucinations. The patient was not confused but it had a hypoproxie, an fixing amnesia, a disorders of judgment and a light left hemiparesia. Cerebral scanner revealed three cerebral cyst. The first measuring 42 x 40 mm, sitting at the level parietal right, to the contact of the occipital horn, dragging his/her/its amputation and an effect of mass on ventricle homolateral, the median line and ventricle controlateral. The two other, at the level of the center semi oval, behind the first, measuring 23 mm and 15 mm on the big axis. The patient has been addressed in neurosurgery. He had a completeray exploration to search other localizations. The thoracic x-ray showed 2 pulmonary cyts. The abdominal scan and imagery by magnetic resonance showed liver cyst, peri-heart cyst and mediastinal cyst. The patient has been operated for these three cysts with good recuperation on the psychiatric and neurological symptoms. He has been addressed in heart surgery for the heart localization. The hydatidose is an endemic illness in Morocco and constitute a public health problem. The cerebral localization is rare and appear by signs of cerebral hypertension and signs of focusing. The psychiatric demonstrations are rare but preserve a major interest, by the therapeutic measure specificity that they impose. Of course, the surgical ablation of the tumor can be sufficient to attenuate the psychiatric symptoms but the recourse to a specific treatment can prove to be necessary to act on the precise targets.

His teacher reported that he has always had a high activity level and difficulty shifting attention between tasks, as well as noncompliance with rules and directions. He is noted to have learning challenges and is showing difficulties in the concept of numbers and letter sounds. The practice has followed Thomas since his healthy birth. He has a history of delayed language development, and he received early intervention services from 2 years of age. He spoke his first word at 2 years 6 months. He started a half-day preschool program at 3 years of age. He had difficulty acclimating to preschool, interacting with peers, and was described as \"hyperactive\" by his teachers. His program was modified to decrease his time having to sit in a circle time, and he often required the support of the paraprofessional in the classroom. His parents have always described him as a \"difficult child.\" He gets frustrated easily and can tantrum for up to 2 hours multiple times in a week when his immediate needs or requests are not met. He has difficulty falling asleep, has frequent night awakenings, and often has trouble getting back to sleep. His self-help skills are poor, and he has difficulty with activities such as brushing his teeth and dressing. His parents report that he does not seem to remember rules from day to day. He was evaluated at 5 years of age and diagnosed with Attention Deficit Hyperactivity Disorder, but his response to stimulants has been limited. Thomas is an only child. His parents are college educated and professionally employed. They deny drug use, domestic violence, and guns in the home.

Agitation can be divided into aggressive agitation, physically nonaggressive agitation, and verbal agitation. Persecutory delusions of suspiciousness and stealing are the most common psychotic symptoms. Auditory and visual hallucinations are also associated with delusions. Similar to delusions are misidentifications, which are false beliefs probably secondary to agnosia. They occur in one third of patients with dementia of the Alzheimer type in the form of the belief that strangers are living in the home and misidentification of the patient's home and reflection in the mirror. Passive personality changes are present early in the disease, whereas agitation and psychotic symptoms occur with disease progression and predict a more rapid rate of cognitive decline. Agitation and wandering are related to more severe cognitive impairment and psychosocial variables, and neurochemical variables that may be related to behavior disturbance require further study. There are few systematic studies of behavioral or environmental interventions for behavioral symptoms in patients with Alzheimer's disease.

From this case, we review the psychiatric aspects of these two autoimmune diseases as described in the literature and we present the etiopathogenic hypothesis and treatment of the psychiatric disorders. Case report--In August 1996, a 38 year old man was admitted in our psychiatric department for agitation. Primary SS had been diagnosed in July 1996. He had previously attempted to suicide but was never hospitalized in a psychiatric department. During the hospitalization in our department, the patient had auditive hallucinations and felt persecuted. He received loxapine 400 mg/day and was remitted in a few days. He was discharged to a convalescent home with the diagnosis of brief psychotic disorder. In October 1996, he was readmitted to our department for agitation. He had shown agitated behavior and aggression in the convalescent home. There were no hallucinations and no affective disorders. He became calm rapidly and was discharged home a few days later. In November 1996, he was found in a coma by a neighbor. He was admitted to an intensive care unit. The lumbar punction revealed blood cells. Cerebral computer tomography showed subarachnoid hemorrhage. The diagnosis was meningeal hemorrhage due to vasculitis. After regaining consciousness, the patient complained of reduced visual acuity. This was believed to be due to retrobulbar neuritis and the patient's vision improved slightly with corticosteroids. The third hospitalization in our department occurred in February 1997 for depression. The patient had shut himself away for days in his apartment. He had suicidal ideas. His mood improved progressively under fluoxetine 40 mg/day. He was discharged to a convalescent home with the diagnosis of major depressive disorder. The fourth and last admission in our department occurred in June 1997. There were disturbances of memory and orientation. He felt sad and guilty about accusation of sexual abuse on his daughter. He presented typical histrionic symptoms: he had catatonic attitudes only in public areas such as the corridors. Cerebral computer tomography and electroencephalogram were normal. There was no biological abnormality. Signs of confusion rapidly disappeared. He felt better after reintroduction of fluoxetine 40 mg/day. Diagnosis was non-specified depressive disorder, but this episode could be retrospectively seen as delirium. After being hospitalized on these four occasions in one year in our psychiatric department, the diagnosis of his systemic disease was revised by rheumatologists. The patient was diagnosed as suffering from systemic lupus erythematosus associated with secondary Sjögren's syndrome. From September 1997, he received cyclophosphamide 2 g intraveinously per month during 6 months. His vision improved dramatically. His ocular dryness became milder. His mood is now stable. He has not suffered from hallucinations or delusion since. Psychiatric disorders in SLE--During the course of SLE, the occurrence of psychiatric manifestations varies widely from 5 to 83%. They include psychotic disorders, major depressive disorders, subtle cognitive disorders and personality disorders of histrionic type. Etiopathogenic hypothesis are: direct activity of the disease on the central nervous system by autoantibodies (antiphospholipide and antiribosome P autoantibodies) (18, 19) or cytokines (interleukin 2, interleukin 6, alpha interferon) (38, 59), side-effects of glucocorticosteroids and hydroxychloroquine (16) or anxious reaction to a chronic and potentially lethal illness (43, 54). Nevertheless, immunologic and cerebral imagery research suggests that psychiatric disorders are related to vasculitis and non-inflammatory vasculopathy of the small cerebral blood vessels. The management of the patients should include treatment of the disease itself and specific psychotropic treatment. Glucocorticosteroids and especially intravenous infusions of immunosuppressive agents, such as cyclophosphamide, are effective. Psychotropic drugs must be used, making sure to avoid SLE-inducing drugs, like chlorpromazine, carbamazepine and lithium carbonate (19, 20, 45). In addition, psychologic care is essential. Psychiatric disorders in SS--During the course of the primary SS, the occurrence of psychiatric disorders is large as well: from 20 to 70% (47, 61, 62). They are mainly major depressive disorders, anxiety disorders, cognitive disorders and dementia. Brief psychotic disorders and delirium are rare. Etiopathogenic hypotheses are similar as those in SLE, with some differences: antiphospholipide and antiribosome P autoantibodies are not usually found in SS and anti-Ro (SSA) autoantibodies in serum are associated with psychiatric disorders (3-11, 61). According to Drosos et al. (29, 30), psychiatric disorders are explained by psychological distress. This slowly progressive fluctuating disease creates constant discomfort from dysphagia, dyspareunia and functional disability. Some of these manifestations can be treated by corticosteroids and psychotropic drugs. Drugs with anticholinergic side-effects, like phenothiazines, tricyclic antidepressants and hydroxyzine which can enhance the oral dryness have to be avoided. Social and psychological support is important too. The diversity of psychiatric morbidity in SLE and SS may be due to differences in patient selection and a lack of uniform clinical criteria. Studies which use standardized diagnostic criteria and control groups don't allow one to come to a conclusion about the relative prevalence of the psychiatric disorders in these autoimmune diseases. This will probably be resolved thanks to the recently published \"American College of Rheumatology nomenclature and case definitions for neuropsychiatric lupus syndromes\" (1). Finally, we can ask ourselves if there is a significant number of undiagnosed SLE and SS in psychiatric departments. Two studies report systematic search for SLE in psychiatric patients. In 1992, Hopkinson et al. (39) searched for several autoantibodies in serum samples of nearly 300 hospitalized psychiatric patients. In 1993, Van Dam et al. (65) did the same with more than 2,000 patients admitted to a psychiatric hospital. Hopkinson et al. found 1% undiagnosed SLE, which is much higher than in general population, and recommended to search SLE in every patient with a high erythrocyte sedimentation rate in psychiatric services. Results of the Van Dam et al. study suggest on the contrary, that SLE is not a common cause of admission to psychiatric hospitals. There is no study which report systematic search of Sjögren's syndrome in a psychiatric department. This is probably because most of patients receive or have recently received psychotropics with anticholinergic side-effects which is an exclusion criteria of SS. Psychiatrists should keep in mind that SLE and primary SS are potential causes of psychiatric manifestations when examining patients with multiple unexplained somatic complaints and psychiatric symptoms. They should then search for autoantibodies in the serum after careful physical examination. Diagnosis of SLE or SS could lead to a better adapted prescription of corticosteroids and/or immunosuppressive drugs and specific psychotropic drugs, making sure to avoid lupus-inducing drugs in SLE and drugs with anticholinergic effects in SS. The existence of psychiatric manifestations in SLE and SS constitutes an indisputable clinical reality that each practitioner must be able to recognize and treat." }, { "id": "pubmed23n0816_3802", "title": "[What you can do when dealing with emergencies in the dementia setting].", "score": 0.009433962264150943, "content": "Frequent emergencies in patients with dementia include aggressiveness, screaming, day/night reversal, other behavioral disorders, and falls.

The parents are very upset as they see their son as very bright. His advanced vocabulary, early reading skills and his extensive knowledge of engines, machines and aircraft were all noted in his medical chart in the past as part of his health supervision visits. He has lots of friends, mostly third graders and plays soccer with moderate success. The paternal grandmother says Casey is just like his dad who is now a biochemical geneticist. He too had a hard time getting his work in as a child and \"always talked back\" to the teacher. Casey's mother would like him on medication before the Iowa Basics come around. The Vanderbilt rating scales by both teacher and parent are positive for inattention and borderline for hyperactivity. Casey took it upon himself to speak to the principal about how bored he was with the classroom work. She agreed that he could have some special assignments. In the pediatrician's office, Casey is a delightful, verbal, thin boy who has about 100 things to talk about, from train engines to the sports scores, acquired from the television sports channel, to what should be done to \"fix\" his school. He said he was bored and knew more about volcanoes than the science teacher. He just wanted to get home each day and work on his elaborate train setup. He doesn't seem overly active, distractible, anxious, inattentive or oppositional. Testing by the school psychologist showed him to have an IQ of 138 with an even verbal/performance profile.

He asked too many questions and argued with the admissions person. They suggested he might need medication before he attempted school.

He was born full-term after vaginal delivery weighing 6 pounds, 6 ounces. There were no pregnancy or delivery complications noted. Genetic testing revealed normal chromosomes, fragile X, and microarray testing. Marcus was a picky eater and good sleeper and had delays in toilet training.There is no family history of attention-deficit hyperactivity disorder (ADHD), autism, or substance abuse. Maternal grandmother and mother have a history of learning difficulties, and his father and a paternal uncle have a history of depression and anxiety. Marcus lives in a supportive environment with his mother, father, and sister.Marcus was noted to have significantly delayed language, stuttering, and immediate echolalia as a toddler. Gross and fine motor milestones were met on time, but he did not talk or follow directions until 4 to 5 years old. As a younger child, he would pretend to talk on the phone or mow the grass with a pretend lawn mower, but other household activities were not of interest to Marcus.Currently, he enjoys puzzles, reading, and board games. He likes to play with other children and can interact with familiar adults. Marcus is reported to initiate social interactions, although he has difficulty in understanding personal space. Imaginative play is preferred over other types. He seeks out adult attention and will bring objects over to an adult especially to share his perceived accomplishment. Marcus has difficulty in playing cooperatively with his sister.He is independent with activities of daily living. Marcus is noted to have auditory defensiveness including covering his ears to loud noises and becoming distressed. Parents feel he is immature and inattentive for his age. Marcus responds well when a routine is followed.Previous testing about 2 years ago revealed significant language deficits on the Clinical Evaluation of Language Functioning with average scores on the Woodcock Johnson Achievement Testing and Test of Nonverbal Intelligence Version 3. Marcus was not referred for early intervention and he did not attend preschool. In a regular education Kindergarten, he received speech and occupational therapy along with reading and math support.Comments from teachers or evaluator include the following: Marcus looked to his peers for clues about what he should be doing. Marcus has great difficulty in understanding requests but seems to be interested in pleasing his teacher and others. Marcus' language difficulty makes socialization with his peers problematic; however, he is interested in interacting with them and they seem to accept him willingly. Marcus has intent to communicate with others but relies on visual support to decipher social situations. Marcus has difficulty in attending to details and moves from activity to activity quickly. His short attention span is likely impacting not only learning but also his ability to socially interact with peers.On the day you see him for his 7-year-old checkup, he brought many toys over to show his father and interrupted your conversation to get your attention intermittently throughout the examination. He immediately pointed out a lit ceiling tile with Nemo illuminated to show his father. Marcus does not have any notable or significant repetitive motor mannerisms or stereotypies reported or observed. Marcus' gesture use was appropriate for age and included both symbolic (directing eye gaze and pointing) and concrete (hands up to be picked up and touching an item rather than pointing to it) gestures. Play observed today, although immature for age, was novel, imaginative, and functional. Answers to questions did not always match the question posed. He had a difficult time waiting for his turn before interrupting a conversation. Visual cues were helpful in understanding what was expected of him and what was going on socially.Marcus' speech is notable for persistent stuttering and difficulty in turn-taking in conversation. He gets frustrated easily and has a hard time being understood. He continues to confuse pronouns and makes some grammatical errors. He is able to follow simple directions but has a hard time following complex or multistep directions with accuracy. Nonverbal communication includes pointing to objects of interest in order to share the experience (\"Look mom!\"). He will point to identify an object and can follow a point across the room. He is able to use his eye contact to direct yours to moderate social interactions.Marcus has a special interest in Thomas the Tank Engine Train and Disney movies but is able to move away from those topics to engage in other play interests. Repetitive behaviors are not noted. Toe walking, hand flapping, or spinning, or unusual hand motions or observation of objects were not observed.Difficulties noted today include delays in his receptive and expressive language, poor intelligibility, dysfluency, and impaired motor planning.

The first case was a 65 year old woman who received a Bjork No 25 aortic valve prosthesis for aortic regurgitation. Two years later oral anti-vitamin K anticoagulants were replaced by an association of Aspirin-Persantine. She developed acute pulmonary oedema secondary to thrombosis of her valve during the fifth postoperative year. Treatment with Urokinase was successful (4 500 U/kg/hour for 24 hours). The second cases was a 33 year old woman who received a Lillehei No 27 mitral valve prosthesis for mitral regurgitation due to infective endocarditis. Six years later, during a period of apparently ineffective oral anticoagulation, she developed subacute pulmonary oedema due to thrombosis of her prosthesis. Urokinase therapy was successful after 4 hours, but the valve surface area on cardiac catheterisation was decreased and elective reoperation to change the prosthesis was decided upon. Prosthetic valve thrombosis is a serious complication with an operative mortality of 68.6% (35 deaths out of 51 reoperations in the worl literature) whilst the efficacy of thrombolytic therapy would appear to be about 80%. When thrombosis is progressive, the valve has to be changed surgically, but when it is secondary, thrombolytic therapy at least helps the patient survive the acute phase." }, { "id": "pubmed23n0746_11191", "title": "Multiple-shower thromboembolism in an artificial mitral valve patient.", "score": 0.013997113997113998, "content": "Late acute left atrial thrombosis is a rare life-threatening complication that mostly appears with predisposing primary coagulopathy, such as Protein C, Protein S, antithrombin 3 deficiency, antiphospholipid syndrome or hyperhomocysteinemia.

Genetic protein C deficiency was discovered. Resumption of vitamin K antagonist therapy was followed by recurrence of skin necrosis despite concomitant administration of heparin. Treatment with vitamin K antagonists could not be continued. This observation is unusual due to the late onset of skin necrosis. The condition usually begins shortly after initiation of vitamin K antagonist therapy, generally between the third and the sixth day of treatment. It is due to a transient hypercoagulable state in patients with protein C deficiency or, in rare cases, protein S deficiency.

The ageing population of the developed world has led to aortic stenosis playing a large part, and the study of its natural history has provided two keynote publications. Aortic valve replacement, increasingly involving older patients, led to the evaluation of this surgery in this age group in which bioprostheses are often associated with coronary bypass surgery. Conversely, in younger patients, there is a regain in interest in autograft (Ross' procedure) or homograft valve replacement which requires a rigorous infrastructure of supply. In mitral valve disease, the indications of conservative surgery of mitral incompetence, ideal in degenerative forms of the posterior leaflet, have been progressively extended to include bacterial endocarditis in many cases and ischaemic mitral regurgitation according to some authors. Rheumatic lesions are not commonly treated by this technique although some encouraging results have been reported. Percutaneous mitral commissurotomy has attained maturity in the treatment of mitral stenosis, even in the less favourable forms such as restenosis after an initial percutaneous procedure or even after surgical commissurotomy. Valve replacement surgery by prosthetic valves is forty year old and many long-term retrospective and prospective evaluations of the results on large patient population either with one type of prosthesis or comparing different bioprostheses or bioprostheses with mechanical valves have been performed. The ideal age for implanting bioprostheses remains uncertain, between 60 and 70, depending on the authors. Finally, problems of anticoagulation in patients with prosthetic valves were the object of three interesting publications about the use of low molecular weight heparin, aspirin and the risks during pregnancy. 2000 was a year of steady and regular progress in the study of valvular heart disease without any major revolutionary contributions." }, { "id": "pubmed23n0278_19328", "title": "[New approaches for treating skin necrosis in protein C deficiency].", "score": 0.010935917835961232, "content": "A 62-year-old woman with a 8-month-history of recurrent deep and superficial vein thrombosis developed multiple areas of skin necrosis during warfarin treatment initiation.

Certainly for the classic but very rare antithrombin defects as well as for the existence of circulating anticoagulant. Possibly for protein C and S defects. On the other hand, the existence of a heterozygotic \"Leiden\" mutation of factor V, or factor II, and an increase of factors VIII, IX, or XI, do not at present warrant a change in AVK prescription. In effect, in the case where the existence of a thrombogenic state implies a prolongation of AVK treatment with its significant potential complications, it is indispensable that the risk/benefit ratio is well founded, which is not the case for these \"new\" thrombophilic states. The coexistence of several of these new biochemical anomalies (for example the association of a factor V and factor II mutation) probably represents an excess risk of thrombosis, but in this situation the reasoning remains the same. On the other hand, faced with a confirmed recurrence, the studies in the literature tell us that very long term treatment should be debated independently from the biochemical results. It is conceivable that there are biochemical anomalies (sometimes quite frequent which should be viewed as \"normal variants\") which, although they have great significance for improving the understanding of venous thrombo-embolic disease, do not at present warrant a change in our therapeutic protocols.

We report a 61-year-old woman with a 12-month history of Raynaud's phenomenon who developed multiple digital necrosis following aortic valve replacement with mechanical prosthesis for aortic insufficiency caused by nonbacterial thrombotic endocarditis. Exacerbation of Raynaud's phenomenon occurred during the postoperative period, with daily episodes of ischemia of the fingers and toes that improved with local warming. However, coincident with the occurrence of immune heparin-induced thrombocytopenia, and while undergoing routine warfarin anticoagulation because of the mechanical valve prosthesis, the patient abruptly developed progression of digital ischemia to multiple digital necrosis on postoperative day 8, at the time the international normalized ratio reached its peak value of 4.3. All limb pulses were readily palpable, and vascular imaging studies showed thrombosis only in the superficial femoral and popliteal veins of the right leg. Coagulation studies showed greatly elevated levels of thrombin-antithrombin complexes and prothrombin fragment F1.2 levels, consistent with uncontrolled thrombin generation. After vitamin K administration, no abnormalities of the protein C anticoagulant pathway were identified, consistent with previous studies of other patients with warfarin-induced necrosis complicating heparin-induced thrombocytopenia. Subsequently, the patient was shown to have metastatic breast adenocarcinoma, which explained the patient's initial presentation with nonbacterial thrombotic endocarditis. This patient case suggests that multiple digital gangrene can result from the interaction of various localizing and systemic factors, including compromised microvascular blood flow (Raynaud's phenomenon), increased thrombin generation (heparin-induced thrombocytopenia, adenocarcinoma), and warfarin-induced failure of the protein C natural anticoagulant pathway." }, { "id": "pubmed23n0089_2044", "title": "[Postoperative pulmonary embolism].", "score": 0.009174311926605505, "content": "Post-operative thrombo-embolic disease remains a frequent occurrence in spite of advances in their prophylaxis.

Due to a thrombosis of the mitral valve, an acute reoperation had to be done 5 years later. 2 years ago, a partially re-thrombosis of the mechanical mitral valve was treated by intravenous thrombolysis. These complications had been probably due to incomplicance. The patient had experienced 3 abortions before. The vaginal sonography determined an intact gestation. The laboratory test revealed an INR of 1.2. The transesophageal echocardiography showed a partially thrombosed mechanical mitral valve. The abdominal ultrasonography detected an embolic splenic infarction. These findings were consistent with partially thrombosed mechanical mitral valve with thromboembolic splenic infarction among incompetent oral anticoagulation.

Treatment with both vitamin K and a single injection of factor IX concentrate led to normalization of the activated partial thromboplastin time and factor IX activity, which remained constant for several days. No acquired factor IX inhibitor was detectable. Analysis of exon 2 of the factor IX gene revealed a C--&gt;T mutation in codon 10 of the propeptide region, resulting in the substitution of alanine by valine. Echocardiography revealed a significant paravalvular leak. The substitution of valine for alanine in the factor IX propeptide leads to an impaired affinity of factor IX to the vitamin K-carboxylase complex. In this situation, treatment with coumarin derivatives can profoundly reduce factor IX activity and result in severe bleeding episodes. This patient was re-exposed to warfarin under close hematological monitoring. After 4 days factor IX activity had decreased to 15%, which was associated with an increase of the aPTT and a mild decrease of the prothrombin time. Due to rapid progression of the paravalvular leak and almost impossible long-term orale anticoagulation with coumarin derivatives, we recommended replacement of the prosthetic mechanical valve with a biological device. The development of severe bleeding in the context of initiating warfarin therapy raises the suspicion of a factor IX propeptide mutation. The initial screening test is the activated partial thromboplastin time, which is elevated in the presence of the mutation. If concomitantly diminished factor IX activity is found the factor IX propeptide mutation should be excluded. Use of lifelong coumarin derivatives is contraindicated in patients with this mutation. However, a general screening of the activated partial thromboplastin time after coumarin initiation is not justified by cost/benefit analysis." } ] } } }

This article looks at current clinical evidence of these items for the management of open fractures. Timing of debridement and wound closure remains critical. Early debridement by an experienced team within 24 h seems adequate while gross contamination, a devascularized limb, a multi-injured patient and compartment syndrome require immediate surgical intervention. Wound closure during the first surgery was shown to result in reduced rates for infections and nonunion. If soft-tissue reconstruction is needed, it should be performed within the first 7 days. Regarding types of irrigation fluid, antiseptic and antibacterial solutions did not prove to be superior to saline. High pressure irrigation has not been demonstrated to be beneficial whereas antibiotic administration as soon as possible has been proven to be favorable. Administration of more than 72 h was not superior to shorter systemic antibiotic intervals. For Gustilo-Anderson type I and II, broad spectrum antibiotic therapy is reasonable.

Additionally, a significant number of studies on this topic have focused on open tibial fractures. A systematic approach to evaluation and management should begin as soon as immediate life-threatening conditions have been stabilized. The Gustilo classification is arguably the most widely used method for characterizing open fractures. A first-generation cephalosporin should be administered as soon as possible. The optimal duration of antibiotics has not been well defined, but they should be continued for 24 hours. There is inconclusive evidence to support either extending the duration or broadening the antibiotic prophylaxis for type Gustilo type III wounds. Urgent surgical irrigation and debridement remains the mainstay of infection eradication, although questions persist regarding the optimal irrigation solution, volume, and delivery pressure.

In cases of bacterial contamination, wound irrigation will be useful with additives such as polyhexanide, octenidine or superoxidized water. Rinsing of the wound should be performed with 3-9 L and only slight manual pressure (no jet lavage). The definitive primary closure of a wound should be achieved in the initial operation, but only in the case of certain \"decontamination\" and overall vitality of the wound (GA I and II). In the presence of high-grade injuries, a temporary vacuum sealing technique can be used until the earliest possible definitive plastic surgical wound closure.

Tibia bone along its anteromedial surface has relatively thin soft tissue coverage; hence the open tibia fracture incidence rate ranges from 49.4% to 63.2%. Open fractures are usually classified based on the Gustilo &amp; Anderson classification system, which is used by surgeons as an index for the severity of an injury and as a prognostic tool. Our current practice follows the 6-h rule of irrigation and debridement (I&amp;D). Nevertheless, there is little support for this opinion in the literature. Our study concentrates on identifying the risk factors of infection in open tibia fractures and comparing the rate of infection if surgical irrigation and debridement was delayed. The medical records of 389 patients with open fractures were reviewed. Of these cases, 113 patients with open tibia fracture who presented to our Hospital from the period 1997 to 2008 fit the inclusion criteria and were included in a retrospective cohort study. A total of 113 tibia fractures were reviewed, with an average patient age of 31.70 years; 87.1% of the fractures were high-energy fractures, and the most common mechanism of injury was a motor vehicle accident (62.4%). The data analysis revealed no difference in overall infectious outcome when comparing initial I&amp;D performed within 6 h to when I&amp;D was performed after 6 h (<iP</i = 0.201). The data analysis showed a significant relationship between infection and wound closure in first surgery in both univariate and multivariate analysis (<iP</i = 0.0003 and <iP</i = 0.014), respectively. This study showed no significant evidence to support the 6-h rule, but it did demonstrate a significant relationship between the Gustilo stage and infection, as well as an increased infection rate if external fixation was used or if the wound was left open during the initial irrigation and debridement.

Negative pressure wound therapy (NPWT) applied to an injured soft tissue coverage provides an impermeable barrier between the injured structures and the external environment, in addition to early secretion draining and a positive effect on the site of application. All this also prevents secondary bacterial contamination. The objective of the study was to compare the results of treatment methods in view of infectious complications in patients with soft tissue injury in grade-III open fractures managed either by NPWT and primary closure or by covering with combined dressing fabric (COM) in combination with continual wound lavage. MATERIAL AND METHODS This retrospective study comprised 77 patients with 80 grade III open fractures treated in the years 2008-2012; of these, 39 patients with 41 fractures met the inclusion criteria and were finally evaluated. The patients were divided into two groups. The control group included 19 patients with 20 fractures treated by the standard surgical procedure using stabilisation with an external fixator or intramedullary nail, thorough soft tissue debridement, continual wound lavage and suture of skin lesions or using a primary coverage of the defect with COM. The trial group consisted of 20 patients with 21 fractures treated according to the same principle, but NPWT was applied to injured soft tissue coverage first and skin suture or any other type of skin defect coverage was carried out when the healing process was good and bacteriological findings were negative. The results of both methods were evaluated based on the following criteria: development of superficial or deep infection in the wound, interval to negative bacteriological findings and osteomyelitis rate. The results were analysed by Fisher's exact test and the Man Whitney U test. RESULTS Infectious complications were recorded in a total of 15 (37%) fractures: 11 (55%) in the control group and four (19.1%) in the trial group (p = 0.025). Recurrent infection was observed in five control group fractures (25%) and in none of the trial group fractures (p = 0.021). Osteomyelitis was found only in two control group fractures. The average interval before negative bacteriological results were obtained was 22 days in the control group and 12 days in the trial group (p = 0.001). DISCUSSION The NPWT use as a temporary coverage of soft tissue defects in open fractures results in a significant reduction of infectious complications, as shown by many relevant studies including this study. In comparison with Gopal's \"fix and flap\" concept, the NPWT in our patient group had slightly higher incidence of infectious complications (15.4% versus 19.1%). However, these results can be achieved only if a specialist in reconstructive surgery and appropriate technical facilities are readily available. If this is not possible, then the NPWT, in comparison with conventional methods, provides the best possible way of temporary protection for an injured soft tissue coverage. CONCLUSIONS Application of NPWT within the primary treatment of injured soft tissue coverage in grade III open fractures results in a statistically significant reduction of bacterial contamination at the site of injury, as well as a reduction of the subsequent incidence of infectious complications. Primary application of NPWT also significantly reduced the risk of recurrent infection. open fracture, negative pressure wound therapy, continual wound lavage, infection." }, { "id": "pubmed23n0716_20288", "title": "[Open fractures of the tibia in the adult: surgical treatment and complications].", "score": 0.014509605662285137, "content": "Open tibial shaft fractures represent high-energy trauma and are associated with a substantial risk of complications.

Four hundred and twenty-two open fractures had emergency irrigation and debridement, fracture stabilization, and open wound management. Wound cultures were obtained for aerobic and anaerobic analysis following debridement. At forty-eight hours after debridement, patients were again returned to surgery. If the initial culture results were positive, a repeat irrigation and debridement was carried out, and additional cultures were obtained after debridement. This procedure was repeated, and the wound was not closed until negative culture results were achieved. Of the 422 open fractures, 346 were available for long-term follow-up. The overall deep infection rate was 4.3%. Gustilo Type-II fractures had a deep infection rate of 4%, and Type-III fractures had an infection rate of 5.7%. Type-III fractures demonstrated differences among the fracture patterns within this type, as infection developed in 1.8% of Type-IIIA injuries, 10.6% of Type-IIIB fractures, and 20% of Type-IIIC fractures. Fractures requiring multiple debridement procedures and those in patients with diabetes or an increased body mass index demonstrated higher rates of infection. With the numbers studied, fractures in which the wound was closed in the presence of positive cultures (a protocol breach) did not have a significantly increased risk of deep infection (p = 0.0501).

We analysed 95 patients with open tibial fractures (Gustilo-Anderson type 1 to 3A) treated with primary fracture stabilisation and either delayed wound closure (group I) or primary wound closure (group II), with a minimum follow-up of 12 months.

Surgical debridement is paramount in preventing detrimental complications such as infection and non-union; however, the exact timing of debridement remains a topic of great controversy. The aim of this study is to evaluate the association between timing of surgical debridement and outcomes such as infection and non-union in open tibial fractures. We performed a systematic review and meta-analysis of the literature to capture studies evaluating the association between timing of initial surgical debridement and infection or non-union, or other reported outcomes. We searched the MEDLINE, PubMed Central, EMBASE, SCOPUS, Cochrane Central and Web of Science electronic databases. Our methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane handbook for systematic reviews of interventions. The systematic review included 20 studies with 10,032 open tibial fractures. The overall infection rate was 14.3% (314 out of 2193) and the overall non-union rate 14.2% (116 out of 817).

These findings did not change when we accounted for the effect of different time thresholds used for defining early and late debridement, nor with the Gustilo-Anderson classification or varying study characteristics. The findings of this meta-analysis support that delayed surgical debridement does not increase the infection or non-union rates in open tibial fracture injuries. Consequently, we propose that a reasonable delay in the initial debridement is acceptable to ensure that optimal management conditions are in place, such that the availability of surgical expertise, skilled staff and equipment are prioritised over getting to surgery rapidly.

Our aims are (1) to determine the proportion of patients with these fractures whose wounds can be treated with early primary wound closure (EPWC); (2) to compare the complication rates between EPWC and delayed wound closure (DWC); and (3) to determine factors associated with higher likelihood of undergoing DWC. At a level-1 pediatric trauma center, 96 patients (younger than 18 y) who sustained Gustilo-Anderson grade II and IIIA open long bone fractures (humerus, radius, ulnar, femur, or tibia) within a 10-year period (2006-2016) were included for this study. Decision for EPWC versus DWC was at the discretion of the attending surgeon at time of initial surgery. Data collection was via retrospective review of charts and radiographs. Particular attention was paid to the incidence of return to operating room rate, nonunion, compartment syndrome, and infection. Median follow-up duration was 7.5 months (interquartile range: 3.6 to 25.3 mo). All patients were followed-up at least until bony union. Overall, 81% of patients (78/96) underwent EPWC. Of the grade II fractures, 86% underwent EPWC. Four patients (5%) in the EPWC group and 1 patient (6%) in the DWC group had at least 1 complication. When controlling for mechanism of injury, Gustilo-Anderson fracture type and age, there was no difference in rate of complications between the EPWC and the DWC groups. Grade IIIA fractures and being involved in a motor vehicle accident were factors associated with a higher likelihood of undergoing DWC. The majority of grade II and IIIA pediatric long bone fractures may be safely treatable with EPWC without additional washouts. Future prospective research is required to further define the subgroups that can benefit from DWC.

Over 855 articles were found due to the search and after applying the exclusion and inclusion criteria 49 studies were finally assessed to contribute to the evidence-based recommendations. Grade A recommendation: early application of antibiotics against gram-positive organisms for all open fracture types, additional coverage of gram-negative organisms for type III open fractures. Early surgical debridement should be performed. Grade B recommendation: type III open fractures should be treated with antibiotics for a minimum of 72 h but not longer than 24 h after wound closure. Vacuum treatment is justified and beneficial if wound closure is not achieved. Grade C recommendation: additional local antibiotic treatment in combination with systematic antibiotics may be of benefit. Definitive wound closure should be achieved within 1 week.

Pre- and post-debridement (using the parameters of Gustilo's classification) wound gradings in 27 children with a mean age of 10 years (3 to 15 years) who had sustained an open tibial fracture were compared. Pre-operative Polaroid photographs of the wound were taken of all these patients in the accident and emergency department. In every case, the fracture was treated with prophylactic intravenous antibiotic administration, wound debridement and lavage. Following wound exploration in the operating theater, the wound was classified using Gustilo's parameters again; this was different from the initial grading. We compared post-debridement classification according to Gustilo to the new classification which we propose. The latter classification is a peroperative assessment of the extent of soft tissue damage and it addresses bone stability. According to this classification, the majority of open tibial fractures were stable, requiring no skin graft or flap and had a good outcome. Only five patients were treated by initial external fixation of the tibia; the remainder were treated by cast immobilization. Wounds were treated as appropriate. The clinical outcome study included the assessment of wound and fracture healing and the incidence of complications. The mean period for follow-up was 8 months (6 to 24 months). There were no cases of nonunion or deep wound infection and the wounds healed in all these patients. We conclude that Gustilo's classification is not specific and does not reflect the extent of soft tissue and skeletal damage. Factors such as the degree of soft tissue damage and periosteal stripping that are noticed following wound debridement and velocity of injury are far more important than the wound size. Our proposed peroperative classification covers the extent of soft tissue injury and skeletal stability, thus predicting the outcome more than the Gustilo classification." }, { "id": "pubmed23n0988_23170", "title": "Negative pressure wound therapy vs. conventional management in open tibia fractures: Systematic review and meta-analysis.", "score": 0.009174311926605505, "content": "Severe open tibia fractures are disastrous injuries associated with a high incidence of complications.

According to her husband, RS was diagnosed with stage IIIA large cell lung cancer 8 months earlier and was treated with concurrent chemotherapy (carboplatin, pemetrexed, and bevacizumab) and radiation therapy that was completed 4 months prior to admission. No other specific information about her treatment or outside health records was available. According to her husband, RS had been in her usual state of health until approximately 3 weeks prior, when she began having significant mental status changes. She first exhibited some difficulty finding words and later was noted to be putting food in a coffee maker. This spontaneously resolved after approximately 1 week; however, she rapidly developed slurred speech and began to make nonsensical statements. These manifestations also slowly improved but were followed by worsening speech deficit, difficulty walking, and impaired balance. During one of these episodes, she had an occurrence of incontinence. Her husband also noted an incident where her \"eyes were beating back and forth and the left side of her face was twitching.\" RS also had periods (according to her husband) where she \"did not seem to be interacting with her environment.\" These progressively worsened during the last week, and she completely stopped walking and talking 2 days prior to coming to the ED. According to her husband, RS had rheumatoid arthritis and no surgical history. Her family history was unknown except that RS's mother had \"seizures.\" RS had reportedly not used tobacco, alcohol, or drugs, and she was sexually active with her husband. Home medications included transdermal fentanyl 12 μg/hr patch changed every 72 hours; oxycodone-acetaminophen tablets 5-325 mg, two every 4 hours as needed for pain; prednisone 10 mg, one tablet daily; and megestrol 40 mg/mL suspension, 20 mL once daily for appetite stimulation. RS was admitted to an inpatient medical oncology service and evaluated by the oncology advanced practitioner (AP) on her second inpatient day. Upon exam, RS was nonverbal except for moaning in response to painful stimuli and to her sister's voice. Her vital signs were normal. She appeared ill but well-nourished, and she was mildly diaphoretic. Neurologic examination revealed that her pupils were slightly sluggish but equal, round, and reactive to light. Extraocular muscle movements were intact, but she did not move her eyes in response to commands. She tracked the AP and family members around the room with her eyes. Cranial nerve examination was intact with the exception of cranial nerves IX, X, and XI, which were difficult to examine given her inability to cooperate and open her mouth. Motor examination revealed increased tone throughout and intermittent, inconsistent resistance to passive movement. She was seen to move all four extremities spontaneously although not in response to commands. Deep tendon reflexes were intact and equal in all extremities. Examination of other body systems was as follows: there was dry, peeling skin on her lips, but her mucous membranes were moist and free of erythema or lesions. Her lungs were clear to auscultation bilaterally. Her heart rate and rhythm were regular, there were no murmurs, rubs, or gallops, and distal pulses were intact. Her abdomen was nondistended with normally active bowel sounds in all four quadrants. Her abdomen was soft, nontender to palpation, and without palpable masses. There was no peripheral discoloration, temperature changes, or edema, and examination of her skin was benign. <bWorkup</b On admission to the emergency department, serum laboratory studies were unrevealing for any potential causes of encephalopathy. Kidney and liver function were normal, making diagnoses of uremic and hepatic encephalopathies less likely. Cultures of the urine and blood were negative. Samples of cerebrospinal fluid (CSF) were obtained via lumbar puncture and were unrevealing for any abnormalities. Computed tomography (CT) of the head without contrast was negative for any acute intracranial process. Ultrasound of the right upper quadrant revealed a single, nonspecific, hypoechoic hepatic lesion. Computed tomography scans of the chest, abdomen, and pelvis demonstrated the primary malignancy in the upper lobe of the left lung, as well as possible metastatic disease within the left lung, right lung, and liver, and widespread osseous metastatic disease. Magnetic resonance imaging (MRI) of the brain performed 1 day after admission demonstrated numerous scattered punctate foci of enhancement throughout the supratentorial and infratentorial brain parenchyma, measuring at most 3 to 4 millimeters in diameter. There was no significant mass effect or midline shift. A paraneoplastic panel was sent to an outside laboratory and returned positive for antivoltage-gated potassium channel (VGKC) autoantibodies. <bDifferential Diagnosis</b Clinically, RS was exhibiting signs of encephalopathy, a broad term that indicates general brain dysfunction, the hallmark of which is altered mental status. Diagnosing encephalopathy is challenging, as many differential diagnoses must be considered. The clinician must consider metabolic derangements, toxic and infectious etiologies, psychiatric disorders, and less commonly, prion disorders and progressive dementia. Cultures of RS's blood and urine as well as other specialized endocrine tests were negative, decreasing the likelihood of a metabolic or infectious cause for her presentation. The abnormalities on her brain MRI were reviewed by a neuro-oncology team, who felt that the faint, nondescript nature of the visualized lesions was not suspicious for metastatic disease. Sequelae of seizures was also considered by neuro-oncology but dismissed given a grossly normal prolonged electroencephalogram. Some encephalopathies are caused by autoimmune or inflammatory mechanisms, which are confirmed by the presence of autoantibody markers and/or clear response to immunomodulatory treatment (Vernino, Geschwind, &amp; Boeve, 2007). These types of encephalopathies have been seen in patients with cancer and have thus been termed paraneoplastic. The presence of anti-VGKC antibodies on RS's paraneoplastic panel directed the inpatient medical oncology team toward a paraneoplastic neurologic disorder (PND) as the most likely diagnosis." }, { "id": "pubmed23n0083_1204", "title": "[A rare and little-known method of elaborating the loss of the object in melancholia].", "score": 0.009708737864077669, "content": "The author presents a fully detailed report of the observation of two economically secure young women who were caught shop-lifting in a large department store; one woman was apprehended while suffering from depression, the other was caught just prior to the onset of a depressive episode. It is hoped that the details referred here may contribute to the insufficient data published on this subject up to the present. It is important to note that the thefts committed by these patients show the typical characteristics of \"impulsive behavior\". Furthermore, the impulse to steal may appear in various psychiatric conditions. Therefore, the author first considered the hypothesis that these thefts may have been computed during an acute dysthymic psychosis. Epilepsy was ruled out in both cases based on anamnestic data, electroencephalographic findings and, even after the administration of a pharmacological trigger, no epileptic symptoms appeared. These negative results prompted the author to propose a psychosemeiogenetic rapport between the depressive conditions and the thefts. Considering basic information regarding the psychodynamic of impulsive behavior in general, and that manifested in the course of melancholia in particular, the author confronts the problem of the psychosemeiogenesis of the impulsive to steal in the depressed patient. In order to understand this problem, the author proposes several interpretative hypotheses (equivalence of suicide or \"parasuicide\" according to Deshaies; attempt to give a concrete reason for the \"feeling of guilt\"; conduct to symbolically compensate the loss of the \"object\"). Following an in-depth, critical discussion, the author concludes that the \"parasuicide\" hypothesis is most accurate in the case of the first patient, whereas \"compensation\" more adequately explains the second.

Jamie is a 19-year-old who was assigned a female gender at birth and had a history of major depressive disorder in remission. She presented to her primary care physician, psychiatrist, and psychotherapist reporting dysphoria related to gender and requesting gender-affirming hormone therapy. Jamie had symptoms for at least 6 months consistent with DSM-5 criteria for gender dysphoria. After full clinical assessment by her therapist, psychiatrist, and primary care physician, her integrated care team initiated gender-affirming hormone therapy and provided close follow-up from her mental health providers. For 13 months, Jamie was treated with testosterone, changed her pronouns to he/him/his, and began wearing traditionally masculine clothing. Throughout this period, she remained engaged in regular care with her psychotherapist, who was experienced in providing gender-affirming care. Eventually, Jamie informed her care team that after the trial of testosterone and much reflection, she had come to understand her identity as a queer woman and wished to discontinue hormone therapy. Jamie reported being pleased about the hormone therapy trial, because this allowed her to clarify her gender identity. She did not regret her social affirmation or any physical changes that occurred during this process, such as fat redistribution and minor facial hair growth, in the context of otherwise being healthy. Lupita is a 23-year-old who was assigned a male gender at birth and had a history of major depressive disorder and panic disorder. At 18 years of age, after a comprehensive evaluation, she initiated gender-affirming hormone therapy with her primary care provider, changed her name to \"Lupita,\" changed her pronouns to she/her/hers, and started wearing more traditionally feminine clothing. That following year, she started attending college and faced continual gender-based harassment from other students as a result of her gender-nonconforming physical appearance. Her college health services were not affirming of her gender and referred to her repeatedly by her birth name and with he-series pronouns. Lupita became demoralized and after 5 months decided to de-transition. She became progressively more depressed and attempted suicide in her sophomore year.

Apropos of a case].", "score": 0.009174311926605505, "content": "The new variant of Creutzfeldt-Jakob disease (nvCJD) was first described in the UK in 1996 (16). The nvCJD differs from sporadic, genetic and iatrogenic CJD. Creutzfeldt-Jakob disease is closely associated with an abnormal isoform PrPSc of a cell-surface glycoprotein, prion protein (14). Molecular analysis suggests that nvCJD is caused by the same prion strain as bovine spongiform encephalopathy (BSE) (4, 10). To the end of September 2000, there have been 82 cases of nvCJD in the UK. We report the second French case of nvCJD to our knowledge (5, 13). This 36 year old woman was referred by a local general practitioner with a 6 month history of psychiatric symptoms of major depressive disorder. According to her family, the patient had suffered from personality change for several months before the onset of depression including apathy, emotional lability, infantile affect. There was no history of health problems. As she was admitted to the psychiatric department of our hospital in Paris suburbs, she presented a major depressive disorder. There were no specific psychiatric features allowing distinction from common depressive disorders, except a marked emotional lability. The patient's condition progressed rapidly within the following days. She presented memory impairment and disorientation. Drug treatments, clomipramine (125 mg/day) and venlafaxine (200 mg/day), were used with no benefit. She presented subsequently transient delusions and auditory hallucinations, fleeting for some hours. The predominant delusional themes were somatic type and pregnancy. The delusions were concomitant with delusions of the onset of cognitive impairment. The patient tested negative for the P 14.3.3 protein in the CSF. Computed tomography scan of the brain did not show any relevant abnormality. The electroencephalogram showed non specific slow wave activity. The neurological symptoms developed 7 months after the onset of depressive symptoms including ataxia, myoclonus, excessive daytime drowsiness, headache. After the onset of neurological symptoms, the illness progressed rapidly over the next 2 months with cognitive impairment, particularly memory impairment, myoclonus, ataxia, incontinence of urine and progressive immobility leading to dependency. CSF tests were negative. She was referred to a neurology department where the diagnosis was confirmed by brain biopsy (detailed elsewhere). The patient died in a state of akinetic mutism. The clinical features of our patient were consistent with previous descriptions of nvCJD, mainly those of the National CJD Surveillance Unit studies (17): early psychiatric symptoms, prolonged duration of illness (median: 14 months), earlier age at death, compared with sporadic CJD. Psychiatric symptoms occur in the clinical course in about a third of cases of sporadic CJD (3). In contrast, of the 35 cases that have died of nvCJD identified in the study by Will et al. (17), 34 suffered from early and prominent psychiatric symptoms, mainly depression and anxiety. In most of the patients, the first symptoms were psychiatric. Drug treatment was used in most cases, some patients had a transient improvement (18). The patient without psychiatric symptoms reported by the NCJDSU (17) was emotionally labile. Infantile affect and emotional lability, found in our patient, are frequently reported in other studies (1, 18). Schizophreniform disorders have been described during the clinical course, with auditory and visual hallucinations and paranoid delusions (17, 18). The insomnia and excessive daytime drowsiness our patient presented have been described in similar cases (18). Investigations are important to rule out alternative diagnoses. EEG records do not show periodic triphasic complexes as in sporadic CJD. The P 14.3.3 protein in the CSF is positive in half the cases of nvCJD (17). First neurological symptoms developed 6 months after the onset of psychiatric symptoms including ataxia, myoclonus and persistent painful sensory symptoms (17, 18). In most of the cases, MRI brain scans show bilateral pulvinar high signal (17), found subsequently in our patient and detailed elsewhere (13). The terminal stages are progressive cognitive impairment, helplessness and akinetic mutism. The first symptoms of this patient were purely psychiatric and difficult to distinguish from common psychiatric disorders. Clinical surveillance of human prion disease is crucial in France, as in UK. The link with BSE has dramatically highlighted the need for neurological and neuropsychological precise investigations." }, { "id": "wiki20220301en105_54144", "title": "Emily Horne", "score": 0.009174311926605505, "content": "Cautions and verdicts In August 2004, Horne was cautioned by the police for two cases of bigamy.

Erin was born at full term. Her birth history was significant for reported maternal treatment for liver failure during pregnancy. Her previous medical history included hospitalization for a viral illness at age 2 months, recurrent ear infections, and a fractured forearm. Family history was significant for a maternal history of bipolar disorder, depression, anxiety, borderline personality disorder, and concern for substance abuse; a paternal history of attention-deficit/hyperactivity disorder (ADHD) and depression; and full biological brother with a history of ADHD and oppositional defiant disorder. Erin and her brother lived with their parents until she was approximately 3 years old. At that time, there were concerns for poor hygiene, inconsistent medical care, poor school attendance for her brother, financial instability, and significant neglect. Erin was reportedly confined to her crib for hours at a time. She and her older brother were removed from the home because of concerns for significant neglect and placed into foster care. Approximately 3 months after foster placement, Erin underwent testing because of concerns for abnormal behaviors and possible developmental delays. Symptoms included poor sleep, repetitive behaviors such as head banging, delayed speech that primarily involved grunting, and lack of toilet training. She was hyperactive and aggressive and had poor caregiver attachment. On evaluation, she was small for age, poorly groomed, and easily distracted with poor eye contact and did not tolerate interactions with examiners. Neuropsychological testing consisted of symptom checklists and caregiver interview only because she did not tolerate diagnostic testing. She was diagnosed with autism spectrum disorder and global developmental delay with intellectual and language impairments. Over the following year, Erin was transitioned to a second foster family and was subsequently adopted. She received speech, occupational, and physical therapy, along with trauma-informed therapy.

Beth reported anhedonia, fatigue and irritable mood, lack of motivation, impaired concentration, and anxiety related to failing grades.You decide to begin medication because of the severity of her symptoms, and 1 week after starting fluoxetine 10 mg, she reportedly overdosed on an unknown quantity of acetaminophen. Within a few days of switching to escitalopram (due to persistent gastrointestinal complaints while taking fluoxetine), she developed homicidal ideation. She reported feeling grandiose, empowered, invincible, elated, and \"crazy,\" although she never demonstrated or endorsed psychotic symptoms. She became fixated upon the idea that she could kill someone and \"get away with it.\" At the time she tried to suffocate a peer with her hands, she was described as having \"a glazed over look in her eyes.\" Moods were now described as alternating between depressed and elated, with mood shifts occurring every few days. These symptoms did not improve after the antidepressant medication was discontinued.Subsequently, patient was admitted for acute psychiatric care, at which time she was described as depressed, but with an \"expansive and irritable\" mood, and with obsessive suicidal ideation. She had developed a plan to hang herself in the home. She started to believe that her mother was trying to give her \"poison.\" She reported panic attacks and said that she wanted to be in the hospital where she could feel \"safe.\" She claimed to have an \"entity inside of her body who was a bully\" and who was \"taking over her body\" and stated that he put her hand over her peer's mouth, as she watched.Psychological testing included the Minnesota Multiphasic Personality Inventory-Adolescent, showed significant paranoia, bizarre mentation, and poor reality testing. Along with interview and observation, it was determined that patient met criteria for the DSM-IV-TR clinical diagnosis of Other Specified Bipolar Disorder, with psychotic features.Aripiprazole was initiated at a dosage of 2 mg; however, moods were still described as fluctuating between extremes every few hours. It was discontinued after reaching 5 mg due to affective blunting. Risperidone 0.5 mg twice daily helped patient to feel and act \"more like herself\"; however, she continued to report significant depression. The addition of lamotrigine 25 mg daily, in addition to individual Dialectical Behavior Therapy, finally led to improvement of mood and a gradual return of her normal baseline, with reportedly stable emotional, social, and academic functioning.The patient's mother remained convinced that this adolescent's mood instability was caused by underlying hormonal problems so you refer her to endocrinology. Beth developed puberty at age 8, with menses occurring on average of twice yearly. She was found to have elevated free testosterone level of 8.6 (reference range, 1.2-7.5). She was of normal weight (body mass index = 21.85 kg/m) and did not manifest acne, male pattern hair thinning, or hirsutism. Thyroid functions, 17-OH progesterone, follicle-stimulating hormone/luteinizing hormone, and estradiol were within normal limits. Prolactin elevation (46.3) was assumed to be due to Risperidone.

The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising &lt;1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with \"playing\" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are \"high-risk\" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a \"hair ball\" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

They tend to be a chronic condition that waxes and wanes according to the circumstances of the patient's life. Patient management poses a particular challenge to the clinician and the prognosis is considered poor. The aetiopathogenesis of factitious disorders in dermatology is not completely understood. We present a case in which we suggested the occurrence of factitious behaviour during a dissociative state, and we briefly describe our diagnostic and therapeutic approach. A 48-year-old unemployed woman was referred to our department of psychiatry by her dermatologist for suspected factitious disorder. The patient was diagnosed with diabetes mellitus type 1 and had been hospitalized repeatedly for confirmed diabetic ketoacidosis. The onset of the disease was related to marital discord with her spouse. Numerous skin lesions had appeared on her face, arms, legs, neck and back. These lesions resulted in multiple hospital admissions and in amputation of her left leg. The condition had worsened considerably after her separation from her husband. During the initial conversation, the patient was unable to provide a clear history of the disease. She denied any knowledge of the circumstances in which these skin lesions appeared, and she did not admit self-infliction. Her mood was depressed and her speech was slow. We suspected that our patient was herself causing her skin lesions while in a dissociative state. Several arguments militate in favour of our hypothesis, particularly her history of childhood maltreatment and the association of traumatic life events with simultaneous deterioration of the skin. The explanation of the dissociative mechanism helped us to strengthen the therapeutic relationship. Within a few days, we noted a slow regression of the lesions, but the patient was still unable to explain how the lesions had occurred. The pathophysiology of factitious disorders in dermatology is poorly understood. It has strong ties with other psychiatric disorders, and according to several authors, skin lesions occur in dissociative states, after which patients do not remember how the skin change started. Management of this disease is challenging. An improved understanding of its mechanisms may enhance the prognosis for this particular group of patients." }, { "id": "wiki20220301en639_23366", "title": "Cheong Chun Yin", "score": 0.008849557522123894, "content": "In the same trial and court, much to the relief of her relatives in court, 60-year-old Pang Siew Fum was also given an approval of her re-sentencing application despite failing to meet the criteria of a courier, as psychiatrists assessed and found Pang to be suffering from major depressive disorder which sufficiently impaired her mental responsibility.

Kevin was placed in the care of his great-great-aunt shortly after he turned 2 years of age because of concerns of neglect. She is now his legal guardian.Kevin is predominately nonverbal but does use a few single words to make requests or label items. He attends a public school and receives full-time special education support. He has a personal care assistant (PCA) who provides in-home support 5 to 6 days/wk for 3 to 4 hours at a time. The PCA is working on toilet training, using a \"clock-training\" approach, and also takes Kevin outdoors to play or on short outings during her visits. In his free time, Kevin prefers to watch cooking shows on television.Over the past year, Kevin's behaviors have become more concerning. There have been several episodes of Kevin waking up during the early morning hours and going to the kitchen to \"cook.\" After one of these episodes, his guardian was not aware that Kevin had woken up until the next morning when she found a concoction of corn starch, coffee grounds, cottage cheese, and powdered drink mix in the blender. Kevin had also woken up during the night and ventured out of the house into the back yard. His guardian had woken up immediately as the alarm system sounded when he opened the outer door from the house to the yard.A door alarm was added to Kevin's bedroom door so that his guardian would be alerted when he leaves his bedroom; however, the alarm is not used consistently because there are times when the alarm cannot be found at bedtime. Kevin's guardian was able to obtain a GPS device for him to wear on his shoe from the local police department.

The patient was well until 15 years of the age when she noted that the ring finger of her left hand at times flexed when she did not intend to do so. She noted weakness in her left upper extremity at the age of 40, and difficulty in relaxing her hand grip at 45. She had an onset of tremor in her right foot at age 50, which was followed by difficulty in gait and hand writing. She was admitted to Juntendo University Urayasu Hospital when she was 63-year-old. Her mother, two sisters, and a son were affected with similar muscle weakness and myotonia. Although some of them developed stooped posture in the late stage of the disease, none of them had overt parkinsonism. General physical examination was unremarkable. Neurologic examination revealed an alert and oriented woman with some recent memory loss. She had bilateral ptosis, facial weakness, and a masked face. Myerson's sign was present. Her speech was small and monotonous. The sternocleidomastoid muscles were markedly atrophic and weak. The remaining of the cranial nerves were intact. She walked in small steps with freezing with support. She showed bradykinesia, retropulsion, and resting tremor in her right leg. Slight distal dominant weakness was noted in both upper and lower extremities more on the left. No cerebellar signs were noted. Muscle stretch reflexes were within normal limits in the upper extremities and diminished in the lower limbs. Sensation was intact. Routine laboratory findings were unremarkable. Cranial CT scan and MRI revealed slight cortical atrophy and leukoaraiosis. She responded to levodopa and she became able to walk by herself. She was transferred to another hospital one month after her admission. She had several bouts of airway obstruction with one episode of respiratory arrest. She expired six month after the transfer. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that this patient suffered from myotonic dystrophy and Parkinson's disease which set in later years. Postmortem examination on the iliopsoas muscle revealed uneven muscle fiber diameters, central nuclei, and type 1 fiber predominance; the pathologic finding was consistent with myotonic dystrophy. The substantia nigra showed marked cell loss and Lewy bodies in the remaining neurons. The finding was consistent with Parkinson's disease. In myelin stain, diffuse myelin pallor was noted in the cerebral white matter which was the pathologic substrate of leukoaraiosis in this patient. Combination of these two disorders have never been reported in the literature to our knowledge. It appears to be that the coincidence is just a by-chance phenomenon, but it seems interesting to note that accelerated aging process appears to be present in both myotonic dystrophy and Parkinson's disease." } ] } } }

Another question that may generate discussion. When a diagnosis of active tuberculosis infection is made, treatment is initiated with isoniazid, rifampicin and pyrazinamide together with ethambutol in case of suspicion of strains resistant to any of the drugs. Once the existence of resistance has been ruled out, ethambutol can be dispensed with. In case of resistance to rifampicin, rifampicin is withdrawn and treatment is completed with the 3 remaining drugs for 12 months. The option of adding a quinolone during the first two months of treatment (moxifloxacin or levofloxacin) is considered in cases of extensive pulmonary involvement. In this case, they do not tell us anything about extensive pulmonary involvement but they give us a data "excessive alcohol consumption". You know that in the MIR no data is free, and if the person who posted this question wanted to reflect it, probably his intention was that we reflect on it. Alcohol exerts a direct immunosuppressive effect, moreover, alcoholism is related to the affectation of immunity in the respiratory tract. The social context that usually accompanies the alcoholic patient does not help either. All the factors mentioned above make us lean more towards answer number 3, although it is undeniable that number 1 could also be correct.

A patient with a history of excessive alcohol consumption has been diagnosed with pulmonary tuberculosis due to cough, fever, expectoration, and sputum culture isolation of Mycobacterium tuberculosis. The patient started treatment with isoniazid, rifampicin, ethambutol and pyrazinamide, with adequate tolerance. Twenty days after starting treatment, a report of rifampicin resistance of M. tuberculosis isolated in sputum is received. Which regimen would you select based on this report?

Ineffective chemotherapy of TB that keeps a substantial proportion of patients alive without cure may amplify resistance during treatment and promote transmission of TB. In 2017, the World Health Organization (WHO) recommended that in patients who require TB retreatment, the retreatment regimen that comprised 8 months of isoniazid, rifampicin and ethambutol supplemented by streptomycin for the initial 2 months, and pyrazinamide for the initial 3 months (2SHRZE/HRZE/5HRE) should no longer be prescribed and drug susceptibility testing (DST) should be conducted to inform the choice of treatment regimen. While GeneXpert MTB/RIF assay may detect rifampicin resistance, it does not detect isoniazid resistance. A 6-month regimen consisting of rifampicin, isoniazid, pyrazinamide and ethambutol may be used for the treatment of previously treated cases in whom rifampicin resistance has been excluded but DST of isoniazid is not available. WHO recommended to treat isoniazid-resistant, rifampicin-susceptible TB (Hr-TB) with rifampicin, ethambutol, pyrazinamide and levofloxacin for a duration of 6 months. In several low- and middle-income countries, the majority of Hr-TB cases are detected after the initiation of treatment with first-line regimens. If patients have an unsatisfactory response to first-line treatment with persistent positive sputum, modification of regimens needs to be done very carefully. Adding a fluoroquinolone in cases with undetected rifampicin resistance runs the risk of acquired fluoroquinolone resistance. Recently, WHO advises NTPs to phase out the injectable-containing short regimen for multidrug-resistant and rifampicin-resistant TB (MDR-/RR-TB) and recommends that the preferred treatment option is a shorter, all-oral, bedaquiline-containing regimen. WHO emphasizes that access to rapid DST, especially for ruling out fluoroquinolone resistance, is required before starting the bedaquiline-containing shorter regimen. The problem is that access to rapid DST for ruling out fluoroquinolone resistance is limited in low- and middle-income countries. The use of WHO-recommended bedaquiline-containing regimens in the treatment of MDR-/RR-TB patients with undetected resistance to fluoroquinolones runs a high risk of acquired bedaquiline resistance, especially in settings with a high prevalence of fluoroquinolone resistance. It is crucial to mitigate the risks of both primary and acquired resistance of rifampicin, fluoroquinolone and bedaquiline by rational design of regimens and effective management of TB patients." }, { "id": "wiki20220301en051_40166", "title": "Denis Mitchison", "score": 0.01257396449704142, "content": "Research The framework of this work was a series of clinical trials in the UK and in larger numbers in East Africa, India, Hong Kong, Singapore and Czechoslovakia.

We selected 63 patients with benign parotid gland surgery, of whom 43 had a pleomorphic adenoma and 20, a Warthin tumour. Of this group of 63 patients, 6 could not be included. We consequently studied 57 patients, 41 of them diagnosed as pleomorphic adenoma and 16, as Warthin tumours. In all of them, a PSP was performed without intraoperative monitoring of the facial nerve. Transient facial nerve paralysis, 14 patients (24.5%). Ten cases were resolved within the first month after surgery and 4 before the third month, after indicating facial physiotherapy. One patient (1.7%) had a permanent difficulty in keeping one side of the lower lip aligned under pressure-mobility, without altering commissure mobility. None of the patients studied had a recurrence (control, 3-13 years). Although PSP is a technique with a few complications, it has a recurrence rate comparable to or lower than other techniques used for the treatment of pleomorphic adenomas or Warthin parotid tumours.

The clinical symptoms include swelling, flushing and hyperhidrosis. The treatment choice for this condition is intracutaneous injection of BTX type A which blocks acetylcholine release at the sweat glands. A 30-year-old man, with thyroid medullar carcinoma diagnosed in 2002 received 6 cicles of cisplatin plus doxorubicin previous to the thyroidectomy with anterolateral neck dissection. During surgery the left ramus marginalis mandibulae was damaged. Two years later the patient referred sweating in submaxillar region during meals. CT scan demonstrated the absence of left submaxillar gland. Minor's test disclosed the affected area and BTX type A was injected (2.5 U/cm2/17 points). A twenty-one-day control showed a 95% reduction of the affected skin area. Persistent efficacy was observed up to one year follow-up time when he was reinjected. The FS, also known as \"gustatory hyperhidrosis\", was probably first reported by M. Duphenix in 1757. Lucja Frey considered its physiopathology as a disorder of both sympathetic and parasympathetic innervation. In our case the FS was caused by a misdirected regeneration of postganglionic parasympathetic nerve fibers that arrised from the nervus lingualis rami ganglionares of the nervus trigeminus. After nerve injury the colinergic parasympathetic fibers seek out colinergic receptors--sympathetic receptors of the skin--innervating sweat glands and small skin vessels.

For some time up until now our Center has achieved excellent results using the group A botulin toxin to overcome the hypertonus of the cricopharyngeal muscle in patients who had undergone laryngectomy and were rehabilitated with voice button. We have sought to extend the use of this toxin to Frey's syndrome, a relatively frequent complication of parotidectomy. A total of 86 patients participated in the study: 41 males (47.6%) and 45 females (52.4%) ranging in age from 25 to 77 years (average age 51 years). Of these patients 7 (8.1%) had undergone post-operative radiotherapy. Of the 86 patients studied, 18 referred significant symptoms in terms of abundance and frequency. The syndrome was considered severe if the symptoms were present at each meal and if the patient indicated a significant worsening of his quality of life. Intermittent episodes were indicated by 22 patients. The remaining 46 (43.5%) did not complain of any symptoms. The exact extension of the cervicofacial gustatory sweating was evaluated using the Minor test and the involved region was divided into 1 square centimeters sections. The amount of skin surface involved ranged from 10 to 80 square centimeters. The type A neurotoxin was frozen and was reconstituted with a sterile saline solution at a final concentration of 2.5 UI/0.1 ml. The intracutaneous infiltration was performed without anesthesia, infiltrating 0.1 ml of solution, containing 2.5 UI of toxin into the center of each 1 square centimeters section. Statistical analysis was performed to evaluate the potential relationship between how long the treatment was effective, incidence of recurrence, seriousness of the crises and the following variables: age, sex, histology, cutaneous surface involved, injected dose of botulin toxin and post-operative radiotherapy. In the group of 18 patients with severe symptoms (20.9%) the benefit was immediate in all cases although the recurrence rate was 50%. The Frey's syndrome symptoms disappeared within 7 days of infiltration. In the group of 22 patients with less severe involvement (25.5%), the treatment gave positive, definitive results in 16 patients (72.7%). Those patients whose symptoms persisted were treated a second time with an infiltration of 2.5 UI per square centimeters. We feel that the use of the type A botulin toxin is the most appropriate treatment for the Frey's syndrome.

After the time of enucleations, pleomorphic adenomas of parotid gland were recommended to be routinely treated with superficial or total parotidectomy. These procedures combine complete tumor removal and identification of the main trunk of facial nerve during surgery to avoid any lesions to the nerve. However, extensive surgery may cause significant morbidity, such as Frey´s syndrome (excessive sweat while eating) and salivary fistula. Also, aesthetic outcome may be compromised.

Patients report facial swelling and sweating at the site of the parotidectomy in occurrence with meals. Etiology is believed to be aberrant innervation of the sweat glands with branches emerging from the auriculotemporal nerve after their division during surgery. This provides parasympathetic innervation to the normally sympathetic-innervated sweat glands [38] . Diagnosis is usually based on patient history, however if there is any doubt an iodine-starch test (Minor test) will confirm the diagnosis, where iodine starch placed on the affected area turns blue signaling sweat secretion. The incidence historically has been reported as high as 50 to 100%, though, with modern techniques and the use of SMAS flaps and thicker skin flaps at the time of initial elevation, this is greatly reduced and is now quite rare.

Methods Retrospective review of the medical records of patients who underwent parotid surgery at age &lt;18 years in two tertiary centers over a 14-year period. Results A total of 18 parotidectomies were performed on 18 patients with a mean age of 13.5 years. All patients presented with a parotid mass. The most common procedure was superficial parotidectomy followed by total parotidectomy. Ten patients were diagnosed with a benign parotid disease (55.6%). The most common benign disease was pleomorphic adenoma. There were eight cases of parotid malignancy constituting 44.4% of all patients and 57% of patients presenting in the age range of 12-17 years. Mucoepidermoid carcinoma was the most common malignancy (six patients). Fine needle aspiration biopsy was performed in 12 children with a sensitivity, specificity, and overall accuracy of 62.5%, 50%, and 58.6%, respectively. The most common complication was temporary facial weakness (33.3%) which resolved in a mean time of 2.5 months. No disease recurrences were identified.

The study subjects were 21 chronic glomerulonephritis patients presenting with spot proteinuria greater than 30 mg/dL and serum creatinine concentrations of &lt;or=1.3 mg/dL in men or &lt;or=1.1 mg/dL in women. All patients were receiving antihypertensive medication or had a blood pressure &gt;or=130/85 mmHg.

In both periods, calcium channel blockers were titrated when the BP exceeded 130/85 mmHg. Blood sampling and urinalysis were performed at the end of each treatment period. The average blood pressure was comparable between the efonidipine and the amlodipine periods (133+/-10/86+/-5 vs. 132+/-8/86+/-5 mmHg). Urinary protein excretion was significantly less in the efonidipine period than in the amlodipine period (1.7+/-1.5 vs. 2.0+/-1.6 g/g creatinine, p=0.04).

Kidney biopsy has been performed routinely in Pisa since 1977; the aim of this study was to report the relative frequency of nephropathies according to gender, age at time of biopsy, clinical presentation and renal function, based on histological diagnoses during the years 1977 through 2005. During this time, 3,810 kidney biopsies were performed, of which 89.3% were from native (n=3,446) and 10.7% from transplant kidneys. Throughout this period, 5% of renal biopsies were not diagnostic, so in this paper we report data regarding 3,269 native kidney nephropathies. During the years 1977 through 2005, data for renal biopsies were collected on specific registers filled out by clinicians. Information collected in the database included a variety of indicators, such as clinical anamnesis, creatinine clearance, daily proteinuria, hemoglobin levels, blood pressure, height and weight, clinical presentation, and current medications. Clinical presentation was defined as urinary abnormalities (UA), nephrotic syndrome (NS) and acute nephritic syndrome (ANS). Renal diseases were divided into 4 major categories: primary glomerulonephritis (GN), secondary GN, tubulointerstitial nephropathies (TIN) and vascular nephropathies (VN). From 1977 up to 1987, a mean of 95 +/- 18 renal biopsies/year were performed; this number significantly increased to 185 +/- 22 renal biopsies/year (range 138-200) (p&lt;0.001) in the following period (1988-2005). Renal biopsy was more frequently performed in males (59%) compared with females (41%). Of all diseases of the native kidney, primary GN was the most frequent (66%), followed by secondary GN (25.6%), TIN (4.2%) and VN (4.2%). The type of primary GN with the highest frequency was mesangial GN (both IgA and non-IgA) (45.7%), followed by membranous GN (23%), focal segmental glomerulosclerosis (19.8%), minimal change disease (5.3%), crescentic GN (4.2%) and postinfectious GN (2%). In terms of age, renal biopsy was more frequently performed in patients aged 20 to 60 years, and nearly 60% of patients presented a glomerular filtration rate (GFR) &gt;60 ml/min at the time of biopsy. The main clinical reason for performing renal biopsy was UA, in all the types of nephropathies. We confirm data that renal diseases are more frequent in men, with the exception of secondary GN. The mean age at diagnosis was 42 years resulting from the tendency not to perform renal biopsies in children and in elderly patients.

Renal survival was also assessed by Kaplan-Meier curves with the log-rank test. The Max GD was significantly correlated with age, body mass index and serum triglyceride levels at the time of renal biopsy. During the 10-year follow-up period, the Max GD was significantly correlated with eGFR decline per year, and proteinuria, but not with hematuria. A multiple regression analysis by the Cox method adjusted for age, sex and eGFR showed that the Max GD values were significantly associated with a 1.5-fold increase in serum creatinine (Cr) values (hazard ratio = 1.04, P = 0.03). Renal function in 66.7% of the patients whose Max GD was ≥242 μm had at least a 1.5-fold increase in their serum Cr value at the 10-year follow-up examination (log-rank, P = 0.003).

The optimal diagnostic cut-off value of GD was 1.99/mm<sup2</sup (AUC = 0.90, sensitivity = 84.0%, specificity = 81.8%) determined by ROC curve. The low GD group (GD &lt; 1.99 per mm<sup2</sup) experienced a significant increase in renal endpoint for patients with eGFR of 30 to 60 ml/min per 1.73 m<sup2</sup (six patients in lower GD group, while one patient in the other group). For patients with time-average proteinuria &lt; 0.5 g/d, the lower GD group showed a higher eGFR decline from baseline (4.5±16.7 ml/min per 1.73 m<sup2</sup vs. -8.1±21.4 ml/min per 1.73 m<sup2</sup, P = 0.038); two patients in this group reached the endpoint, while no patients in the higher GD group did. Conclusion GD could be an independent prognostic factor for patients of IgA nephropathy with eGFR at 30 to 60 ml/min per 1.73 m<sup2</sup of body surface, particularly for those with time-averaged amount of urine protein less than 0.5 g per day." }, { "id": "wiki20220301en033_21958", "title": "Acute pancreatitis", "score": 0.00909090909090909, "content": "At admission age in years > 55 years white blood cell count > 16000 cells/mm3 blood glucose > 11.1 mmol/L (> 200 mg/dL) serum AST > 250 IU/L serum LDH > 350 IU/L At 48 hours Calcium (serum calcium < 2.0 mmol/L (< 8.0 mg/dL) Hematocrit fall >10% Oxygen (hypoxemia PO2 < 60 mmHg) BUN increased by 1.8 or more mmol/L (5 or more mg/dL) after IV fluid hydration Base deficit (negative base excess) > 4 mEq/L Sequestration of fluids > 6 L The criteria for point assignment is that a certain breakpoint be met at any time during that 48 hour period, so that in some situations it can be calculated shortly after admission.

The aim of this report is to analyze the incidence and the variations in frequencies of the histological diagnosis and clinical presentation during the 1980-2003 period. From the 2,058 patients with renal biopsy in the whole period, we analyzed the histological diagnosis and the following data has been collected when the patients were registered: age, gender, clinical syndrome, proteinuria, hematuria, serum creatinine, blood pressure and time from the first symptom. Four periods of registry entry were considered: 1980-1989, 1990-1994, 1995-1999 and 2000-2003. Chi-square and Student test for independent samples were used to evaluate the differences among the variables frequencies in the four periods. The incidence of registered glomerulopathies per million population (pmp) increased from 13 (1980-1989) to 43 (2000-2003). In the 2000-2003 period, the incidences pmp were: primary glomerulopathy (PG), 25.3 and secondary glomerulopathy, 14.2. The highest incidences pmp were: focal and segmental glomeruloesclerosis (FSGS) 6.4; vasculitis 5.4; lupus nephritis 4.6; minimal change disease (MCD) 4.6; IgA nephropathy (IgAN) 4.5; and membranous nephropathy (MN) 4.0. The most frequent PG were the FSGS (29.3%) and the MCID (19.6%). The FSGS frequency decreased from 36.3% in 1995-1999 to 19.1% in 2000-2003. The IgAN frequency increased from 5.2% in 1980-1989 to 17.5% in 2000-2003. Nephrotic syndrome was the most frequent clinical presentation; its frequency was over 30% in the four periods.

The histological diagnosis leading to the NS was focal segmental glomerulosclerosis (FSGS) in 51% (n = 42), IgM nephropathy in 20% (n = 17), membranoproliferative glomerulonephritis in 10% (n = 8), lupus nephritis in 6% (n = 5), human immunodeficiency virus (HIV) nephropathy in 5% (n = 4), minimal change disease in 7% (n = 6), and membranous nephropathy in 1% (n = 1) of patients.

There was a rise in serum creatinine following the use of CSA in patients with FSGS, lupus nephritis, and HIV nephropathy; however the elevated serum creatinine was only significant in patients with FSGS. At the end of the study period, 20 patients had reached ESRD, of which 11 had FSGS, 5 had lupus nephritis, and 4 were patients with HIV nephropathy. Fifty-four patients were in remission at the end of the study period (48 with proteinuria &lt; 100 mg/24 h and 6 with proteinuria &lt; 500 mg/24 h). In conclusion, among children with refractory NS, CSA induced a remission in a large proportion. However toxicity, as noted by the rise in serum creatinine, was observed in several patients.

The histologic features of 244 cases of IgAN (not including Schönlein-Hanoch nephritis) diagnosed between 1980 and 1994 were reviewed, and each case was subclassified using the following, relatively simple histologic classification scheme: subclass I (39 cases): minimal or no mesangial hypercellularity, without glomerular sclerosis; subclass II (18 cases): focal and segmental glomerular sclerosis without active cellular proliferation; subclass III (110 cases): focal proliferative GN; and subclass IV (42 cases): diffuse proliferative GN; and subclass V (35 cases): any biopsy showing &gt; or = 40% globally sclerotic glomeruli and/or &gt; or = 40% estimated cortical tubular atrophy or loss.

On admission, general physical examination was unremarkable, and neurologic examination revealed a mentally sound man with slight dysarthria, right facial weakness, orolingual dyskinesia, and dysequilibrium in which he showed difficulty in tandem gait; however, no cerebellar ataxia was noted. A cranial CT scan revealed leukoaraiosis with multiple low density areas in the cerebral white matter. His BUN was 37 mg/dl and Cr 2.2 mg/dl. His neurologic symptoms cleared within the next few weeks and he was discharged with ticlopidine 100 mg q.d.. He had been doing well after the discharge except for gradual worsening of his renal function; his BUN was 65 mg/dl and Cr 3.27 mg/dl in April of 1994.

There was an 1 + pitting pretibial edema; otherwise general physical examination was unremarkable. Neurologic examination revealed an alert and oriented man, however, Hasegawa's dementia scale was 23/30. Higher cerebral functions as well as cranial nerves were intact. He showed some unsteadiness of gait, however, no motor weakness or ataxia was noted. Deep tendon reflexes were diminished, but Chaddock sign was positive bilaterally. Vibration was diminished in the feet, however, pain and touch sensations were intact. Laboratory examination revealed a compression fracture of the twelfth thoracic vertebra.

A urine specimen contained 1 + protein and 1 + glucose, and the sediments contained hyaline casts. A cranial CT scan was essentially same as that taken four years ago. His hospital course was complicated with pneumonia, congestive heart failure, and progressive renal failure. He was treated with intravenous fluid, chemotherapy, and other supportive measures, however, he expired from respiratory failure on April 30, 1995. He was discussed in a neurologic CPC, and the chief discussant arrived at the conclusion that the patient had Binswanger's disease in the brain, benign nephrosclerosis from arteriolosclerosis due to hypertension, congestive heart failure, and pneumonia. Opinions were divided regarding the question as to whether or not this patient had Binswanger's disease. Although his cranial CT scan revealed leukoaraiosis, his dementia and gait disturbance was only mild until his fall on March, 1995. Clinical features did not conform to those of Binswanger's disease. Postmortem examination of the right hemisphere revealed wide spread atherosclerosis and arteriolosclerosis. The kidney showed benign nephrosclerosis due to arteriolosclerosis. Sclerotic changes were also seen in the coronary arteries and the left middle cerebral artery with 70% stenosis. Myelin stain showed diffuse myelin pallor of the cerebral white matters with scattered small infarcts. Arterioles in the white matter showed arteriolosclerosis. Small infarcts were also seen in the putamen and in the thalamus. This patient appeared to have had circulatory disturbance of the white matter which is the basic abnormality causing Binswanger's disease. However, white matter changes in this patient were not quite severe enough to make a pathologic diagnosis of Binswanger's disease." } ] } } }

We are dealing with a patient who has exhausted the pharmacological route given that he takes everything and has two important problems: genu varum and an important gonarthrosis. This means that we can do nothing with an arthroscopy, let alone a synovectomy (1 and 5 false). The genu varum could falsely make us think about an osteotomy, however even if we did it and corrected the varus now the damage is already done and the osteoarthrosis is severe. Perhaps years ago before the osteoarthritis took place it would have been resolutive but not now (4 false). In addition, in order to consider an osteotomy, we should be given more data to know which bone to apply the osteotomy on, the tibia or the femur. Finally, we may think that it is best to first try rehabilitation before considering surgery, but I discard this option because the question emphasizes that we have exhausted pharmacological measures (although it could be considered because they have not specified whether it has been tried or not). In any case with the knee prosthesis we correct the problem of osteoarthritis pain and we can also correct the knee varus.

QUESTIONS ASKED: Does arthroscopic lavage improve motor function and pain associated with OA of the knee?Does arthroscopic debridement improve motor function and pain associated with OA of the knee?If evidence for effectiveness can be established, what is the duration of effect?What are the adverse effects of these procedures?What are the economic considerations if evidence for effectiveness can be established? Osteoarthritis, the most common rheumatologic musculoskeletal disorder, affects about 10% of the Canadian adult population. Although the natural history of OA is not known, it is a degenerative condition that affects the bone cartilage in the joint. It can be diagnosed at earlier ages, particularly within the sports injuries population, though the prevalence of non-injury-related OA increases with increasing age and varies with gender, with women being twice as likely as men to be diagnosed with this condition. Thus, with an aging population, the impact of OA on the health care system is expected to be considerable. Treatments for OA of the knee include conservative or nonpharmacological therapy, like physiotherapy, weight management and exercise; and more generally, intra-articular injections, arthroscopic surgery and knee replacement surgery. Whereas knee replacement surgery is considered an end-of-line intervention, the less invasive surgical procedures of lavage or debridement may be recommended for earlier and more severe disease. Both arthroscopic lavage and debridement are generally indicated in patients with knee joint pain, with or without mechanical problems, that are refractory to medical therapy. The clinical utility of these procedures is unclear, hence, the assessment of their effectiveness in this review. LAVAGE AND DEBRIDEMENT: Arthroscopic lavage involves the visually guided introduction of saline solution into the knee joint and removal of fluid, with the intent of extracting any excess fluids and loose bodies that may be in the knee joint. Debridement, in comparison, may include the introduction of saline into the joint, in addition to the smoothening of bone surface without any further intervention (less invasive forms of debridement), or the addition of more invasive procedures such as abrasion, partial or full meniscectomy, synovectomy, or osteotomy (referred to as debridement in combination with meniscectomy or other procedures). The focus of this health technology assessment is on the effectiveness of lavage, and debridement (with or without meniscal tear resection). THE MEDICAL ADVISORY SECRETARIAT FOLLOWED ITS STANDARD PROCEDURES AND SEARCHED THESE ELECTRONIC DATABASES: Ovid MEDLINE, EMBASE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and The International Network of Agencies for Health Technology Assessment. THE KEYWORDS SEARCHED WERE: arthroscopy, debridement, lavage, wound irrigation, or curettage; arthritis, rheumatoid, osteoarthritis; osteoarthritis, knee; knee or knee joint. TIME FRAME: Only 2 previous health technology assessments were identified, one of which was an update of the other, and included 3 of 4 randomized controlled trials (RCTs) from the first report. Therefore, the search period for inclusion of studies in this assessment was January 1, 1995 to April 24, 2005. EXCLUDED WERE: case reports, comments, editorials, and letters. Identified were 335 references, including previously published health technology assessments, and 5 articles located through a manual search of references from published articles and health technology assessments. These were examined against the criteria, as described below, which resulted in the inclusion of 1 health technology assessment and its corresponding update, and 4 articles (2 RCTs and 2 level 4 studies) for arthroscopic lavage and 8 papers (2 RCTs and 6 level 4 studies) for arthroscopic debridement.

Arthroscopic lavage or debridement, with or without meniscectomy, for the treatment of motor function symptoms and pain associated with OA of the knee. Studies in which there was a comparison group of either diseased or healthy subjects or one in which subjects were their own control were included. Comparisons to other treatments included placebo (or sham) arthroscopy. Sham arthroscopy involved making small incisions and manipulating the knee, without the insertion of instruments. IN EARLY OA OF THE KNEE WITH PAIN REFRACTORY TO MEDICAL TREATMENT, THERE IS LEVEL 1B EVIDENCE THAT: Arthroscopic lavage gives rise to a statistically significant, but not clinically meaningful effect in improving pain (WOMAC pain and VAS pain) up to 12 months following surgery. The effect on joint function (WOMAC function) and the primary outcome (WOMAC aggregate) was neither statistically nor clinically significant. IN MODERATE OR SEVERE OA OF THE KNEE WITH PAIN REFRACTORY TO MEDICAL TREATMENT, THERE IS: Level 1b evidence that the effect on pain and function of arthroscopic lavage (10 L saline) and debridement (with 10 L saline lavage) is not statistically significant up to 24 months following surgery.Level 2 evidence that arthroscopic debridement (with 3 L saline lavage) is effective in the control of pain in severe OA of the medial femoral condyle for up to 5 years.For debridement in combination with meniscectomy, there is level 4 evidence that the procedure, as appropriate, might be effective in earlier stages, unicompartmental disease, shorter symptom duration, sudden onset of mechanical symptoms, and preoperative full range of motion. However, as these findings are derived from very poor quality evidence, the identification of subsets of patients that may benefit from this procedure requires further testing.In patients with pain due to a meniscal tear, of the medial compartment in particular, repair of the meniscus results in better pain control at 2 years following surgery than if the pain is attributable to other causes. There is insufficient evidence to comment on the effectiveness of lateral meniscus repair on pain control. Arthroscopic debridement of the knee has thus far only been found to be effective for medial compartmental OA. All other indications should be reviewed with a view to reducing arthroscopic debridement as an effective therapy. Arthroscopic lavage of the knee is not indicated for any stage of OA. There is very poor quality evidence on the effectiveness of debridement with partial meniscectomy in the case of meniscal tears in OA of the knee." }, { "id": "pubmed23n0517_23193", "title": "Debridement and continuous irrigation for the treatment of pyogenic arthritis caused by the use of intra-articular injection in the osteoarthritic knee: indications and outcomes.", "score": 0.016464699683877766, "content": "To discuss the indications and therapeutic outcomes of synovectomy, debridement, and continuous irrigation for the treatment of pyogenic arthritis caused by intra-articular injection used in the treatment of osteoarthritis of the knee. Records of 41 patients with infectious arthritis of the knee who presented to our hospital from 1981 were reviewed. 11 of them had a history of intra-articular injection. They underwent synovectomy, debridement, and continuous irrigation using a Salem double-lumen tube after confirmation that one side of the femorotibial joint cartilage was basically healthy. The infection was successfully treated in 9 of the 11 patients. Of these 9 patients, one died after 3 years and 2 underwent total knee arthroplasty after 3 and 8 years. The remaining 6 patients were followed up for 5 to 15 years. Five of them had deteriorating arthropathy, and the condition was unchanged in the others. Two of these 6 patients had pain while walking, and their Japanese Orthopaedic Association scores were 70. The remaining 4 had good knee function and reduction of pain, with a mean Japanese Orthopaedic Association score of 91 and a mean range of motion of 131 degrees. Arthrodesis is frequently considered the treatment for osteoarthritis if the joint destruction has affected the weight-bearing surface. However, in our experience, even when inflammatory granulation develops in the cartilage surface of one side of the femorotibial joint, good results can still be obtained by synovectomy, debridement, and continuous irrigation. After the pyogenic arthritis has subsided, if osteoarthritis has advanced and bowleg has exacerbated, further treatment options are available, such as tibial resection and even joint replacement. Continuous irrigation should be considered a feasible treatment option for pyogenic arthritis." }, { "id": "wiki20220301en068_12266", "title": "Knee replacement", "score": 0.01201923076923077, "content": "It is important to explore multiple rehabilitation protocols used for recovery of total knee arthroplasty.

Patient counseling is important in order to discuss the nature of the underlying disease process, the limited goals of the arthroscopic procedure, and the possible need for further surgery. Proximal tibial osteotomy for the treatment of medial compartment osteoarthritis can be effective for as long as 15 years. There is a deterioration of results over time that can often be correlated to the degree of correction achieved. Strict selection criteria can maximize success. Revision surgery to total knee replacement, albeit technically difficult, is a viable option with results similar to primary TKR. Unicompartmental knee arthroplasty remains a controversial procedure as its indications continue to evolve. Good to excellent results can be expected in 80% to 90% of patients at 10 years follow-up. Unicompartmental knee arthroplasty occupies a special niche in the treatment of unicompartmental osteoarthritis and supplements total knee replacement and high tibial osteotomy surgery." }, { "id": "pubmed23n0249_12596", "title": "Guidelines for the medical management of osteoarthritis.

In individuals with mild symptomatic OA, treatment may be limited to patient education, physical and occupational therapy and other nonpharmacologic modalities, and pharmacologic therapy including non-opioid oral and topical analgesics. In patients who are unresponsive to this treatment regimen, the use of NSAIDs in addition to nonpharmacologic therapy is appropriate unless medically contraindicated. Judicious use of intraarticular steroid injections has a role either as monotherapy or an adjunct to systemic therapy in patients with knee OA who have symptomatic effusions. The role of joint lavage and arthroscopic debridement in patients with OA of the knee who are unresponsive to conservative medical therapy needs further study, and these procedures cannot be routinely recommended for all patients at this time. Patients with severe symptomatic OA of the knee require an aggressive approach to decreasing pain, increasing mobility, and decreasing functional impairment; such patients may benefit from orthopedic consultation and evaluation for osteotomy or total joint arthroplasty." }, { "id": "pubmed23n0631_13275", "title": "Arthroscopic joint lavage in osteoarthritis of the knee.

The duration of symptoms prior to arthroscopic debridement was 4.5 days (range, one to 14 days). In 8 patients the infection was hematogenous. 5 patients had post-operative infection, 2 had post-traumatic infection and one infection followed an intraarticular injection. All the patients were treated by arthroscopic debridement and irrigation of the knee. A partial synovectomy of the anterior compartment was carried out in 4 cases in which the infection diagnosis was delayed. In 6 patients with resistant germ or early unfavorable course (clinically or biologically), an early iterative arthroscopy was performed between 2 and 7 days after the first procedure. The medical treatment consisted in a double systemic antibiotherapy for an average duration of 4 weeks, followed by oral treatment for 3 weeks. The patients were encouraged to mobilize their knee as soon as C Reactiv Protein was normal (average 3 weeks, 0 to 12). The average follow up was 20.5 months (2 to 60).

Knee pain is pain caused by wear and tear, such as osteoarthritis or a meniscal tear. Effective treatments for knee pain include physical therapy exercises, pain-reducing drugs such as ibuprofen, joint stretching, knee replacement surgery, and weight loss in people who are overweight.

Where the support surfaces of most prostheses remain limited, even punctiform, the originality of the Goodfellow prosthesis lies in the fact that the prosthetic condyle, whatever the flexion angle is, leans against a mobile prosthetic meniscus with spheric superior concavity of the same radius as the condylian radius, which increases considerably the prosthetic leaning surfaces and therefore lessens the pressure constraints. The superior surface, concave, of this prosthetic meniscus takes charge of the rolling, where the inferior plane surface realizes the gliding on the metallic tibial plate. The total conformity of the components minimizes the forces of friction.Between July 1988 and March 1993, 24 patients underwent the placing of UCP. Three patients died and 2 were lost of sight. 19 patients could be seen again or checked, corresponding of 21 operated knees. Two knees benefited from the start from UCP (medial and lateral) and 2 knees had a UCP in the first instance and then a second UCP in the compartment left safe primarily. For the 21 UCP, there are 16 medial and 3 lateral. Our mean drawback is of 3 years and 3 months, all the drawbacks being superior to 1 year and 4 months. The mean age is of 64 years. There were 17 female and 2 male patients. The mean weight is of nearly 80 kg (79,8) and nearly 52% of the operated patients have an important overweight (Body Mass Index superior to 30). Preoperative clinical analysis. It is based on a retrospective study of files using the quotation described by AUBRIOT for the «GUEPAR» group. This one establishes a gradation of four levels for each of the three criteria retained (Pain, Mobility, Instability), thus determining a global result imposed by the lowest level retained.For walking, other factors than just the state of the operated knee may intervene, this being the reason why it doesn't show in this chart. The GUEPAR group quantifies it with letters A, B, C, D.Concerning pain, all 21 knees were quoted as \"Bad\" in preoperative. Pain constitutes the decisive argument for the operative indication. In our series, only one knee had an average amplitude, all the others had a mobility superior to 89°. In 5 cases there was a flessum between 11 and 20° (penalizing of a level). Concerning walking and stability, they were taken into account, thanks to a precise questionnaire about the daily life acts. Concerning the walking perimeter, it was found as unlimited (A) in 1 case, superior to 500 m (B) in 2 cases, inferior to 500 m (C) in 17 cases and limited to home (D) in 1 case. The early after effects. At the end of the intervention, the knee is placed into a splint with limited flexion. As soon as the second day the patient is sat on the border of his bed. The first partial support at the third of the body weight is authorized between the fourth and the fifth day, when at the same time flexion exercises on electrical splint are started, as soon as the Redon draining is removed. The average hospitalization length was of a fortnight. Among secondary late complications and retakes, let us stop on meniscal luxations which constitute a specific complication of the Oxford arthroplasty. They concern 3 times the medial compartment and 4 lateral compartment. They happened in 1 case early, at D 22, in 3 cases within the 6 first months and in 3 cases after 2 years. They were treated : 3 times by reduction under general anæsthetic, no more ; 3 times changing the meniscusus for a meniscusus of superior size and once by placing a total prosthesis at the place of the UCP. The deteriorations of the opposed compartment not prosthesized occured in three cases. They were treated by unicompartmental additional arthroplasty in two cases and by total prosthesis in the third case. The clinical results on pain are very satisfactory as from the early check up onwards we have 17 successes (no pain 11 cases and occasional pains 6 cases) and as after 3 years and 5 months in average, we have 19 successes (no pain : 10 cases - occasional pain : 9 cases). At the maximal drawback, the mobility is quoted very good in 7 cases and good in 13 cases, mean in 1 case. At the latest check up, we note an excellent stability in 17 cases and good in 3 cases, that is to say 20 successes and 1 case of stability quoted as mean. At the latest check up we note 17 successes (A and B) and 4 relative failures (C) concerning the quality of walking.At the question «are you pleased with the intervention and would you advise it to a friend?» and with the nuance «very pleased» and «simply satisfied», we get 10 cases «very pleased», 8 cases «pleased» and 3 cases «moderately satisfied»; only those 3 cases advise against the intervention. The radiological results are less satisfying as they show frequent imperfections : • for the 16 medial UCP : only 9 cases hypocorrected or normo axed, but 1 case strongly hypocorrected (residual varus of 7°) and 6 hypercorrected cases. • for the 5 lateral UCP : 3 normo-axed cases, 1 case strongly hypocorrected (residual valgus of 6°) and 1 case strongly hypercorrected (10° varus). • the failures due to rapid deterioration of the non prosthetized compartment occurred on hypercorrected knees. • on 21 knees, 14 borders of tibial plate were noticed, out of which 9 had no plate displacement and 5 had a slight displacement, at the origin of a small angular loss. • accumulations of cement on the tibial side, towards the back or in medial were noticed in 8 cases, which explains a slope of the tibial plate to the back inferior to 5° in 11 cases (should be of 7°). • 4 femoral components seem to be too posterior and one shows curved.In total, only 7 cases out of 21 were estimated with no peculiarities on the radiological point of view. It seems difficult to place a UCP well. The meniscal luxations are favored by an alignment rotational defect of the tibial plate, specially for the lateral UCP, the meniscus coming to hit the lip of the tibial plate during the lifting from a sitting position. For 5 of these luxations, we must recognize the existence of a ligamentary collateral laxity which should have altered the surgical indication either to an osteotomy, or to a total arthroplasty. Conclusions. Under the condition of respecting the absolute counter indications, of thoroughly evaluating the relative counter indications and of reducing at the best the defects linked to the surgical technique, the unicompartmental arthroplasty, including that of Oxford, gives good functional results after more than three years. In our series, the result on pain is constant if we exclude the cases with risk with ligamentary laxity and that of centered gonarthrosis at obese subject, that is to say 15 successes on 15 knees thus selected retrospectively. The gain on mobility is weak, of 5° in average. The result on stability is, as for pain, excellent, if we exclude the cases with risk, as we get then also 15 successes on 15 knees. Concerning the global result according to the quotation of Aubriot-Guepar, we note 14 successes and 1 relative failure. 4 knees were bad indications and should have benefited from a total arthroplasty or from an osteotomy.

In addition, we wanted to study if sole sagittal corrections change the coronal alignment. Seventy-six patients with a minimum follow-up of 6 months were identified, who underwent a sole sagittal correction (anterior closed-wedge high tibial osteotomy (ACW-HTO)) or a combined procedure with an additional coronal realignment (medial open-wedge high tibial osteotomy (MOW-HTO)). In ACW-HTO, either infratuberosity or supratuberosity approaches were used.

 A total of 15 patients received total knee arthroplasty for correcting mild (10°-15°) to moderate (15°-30°) valgus knee between January 2011 and February 2014 in Xiangya Hospital of Central South University. We adopted a stable prosthesis surgery through patellar medial approach, osteophytes cleaning, conventional osteotomy, a selective soft tissue release and balance technical correcting of knee valgus deformity. Then conventional anticoagulation and symptomatic rehabilitation was utilized. Preoperative and postoperative X-ray was conducted in patients with measuring femor-tibial angle (FTA) and inspecting the prosthesis position. FTA, visual analog scale (VAS) standard, and parallel knee scoring system (KSS) were used to evaluate the clinical effect.
 Fifteen patients were followed up for 14 to 36 (22.40±11.88) months. The hospitalization time was 7-13 (7.73±1.58) d; operative time was 58-110 (81.8±16.85) min, the dominant blood loss was 140-600 (337.30±143.65) mL. Two cases had knee extension hysteresis, and the knee activity recovered after exercise. Leg power lines were normal. Three postoperative cases suffered anterior knee pain. They were subjected to celecoxib analgesic treatment and the pain gradually eased after 3 months. One postoperative case showed incision discharge and swelling, which was healed after change of dressing. During follow-up, review of X-ray film does not show prosthesis loose, subsidence and other complications.

Group 1 included 6 patients with 6 knees who underwent arthroplasty within 3 years after osteotomy. The main reason for revision arthroplasty in Group 1 was pain due to the recurrence of a varus deformity. Group 2 included 5 patients (6 knees) who underwent revision arthroplasty more than 5 years after osteotomy. The main reason for revision arthroplasty in Group 2 was pain or hydrarthrosis due to the progression to bi-compartmental or tri-compartmental osteoarthritis. There was no significant difference in the clinical results between the two groups. Concerning patellar height, LT/LP of Group 1 was significantly lower than that of Group 2. There were no significant differences in the radiographic findings among the two study groups and the control group of 71 patients (110 knees) who underwent primary total knee arthroplasty, except for alignment before arthroplasty.

Catheter angiography also offers the possibility of coiling an aneurysm (see below). In emergency department patients complaining of acute-onset headache without significant risk factors for SAH, evidence suggests that CT scanning of the head followed by CT angiography can reliably exclude SAH without the need for a lumbar puncture.

This study aims to draw attention to the use of cranial computerized tomography (CT) scans in the evaluation of children with head trauma under the age of 18, and to determine CT scans' usefulness in terms of cost-effectiveness. Age, gender, mechanism of trauma and Glasgow Coma Scale (GCS), diagnosis, time of admission to hospital, hospitalization and operation, cranial computerized tomography and hospitalization costs of all cases were retrospectively analyzed. A total of 26,412 patients younger than 18 years old who were admitted to the emergency department due to head trauma and who had a cranial tomography were analyzed. They had a mean age of 7.74 ± 5.66 years. In total, 26,363 (99.8%) of these patients had a GCS greater than 14. Out of these patients, only 402 (1.5%) had brain injury revealed by cranial CT, 41 (0.2%) of these patients were operated and 3 of the patients lost their lives. The total cost of patients admitted to the emergency department with a head injury amounts to USD 583,317. Furthermore, 75.78% of this cost comes from negative cranial CTs. A cost analysis according to different age groups did not show a meaningful difference between 0-2 years and 3-5 years (<ip</i = 1.000), but there was a meaningful difference for all the other age groups. Our findings show that applying algorithms to predict traumatic brain injury in children with mild head injury rather than scanning all patients with cranial CT will enable more reliable and cost-effective patient care. Current practices should be reviewed to avoid unnecessary radiation exposure and expense in the ED. It is also necessary to inform and educate parents about the risk/benefit ratio of cranial CT scans." }, { "id": "pubmed23n1033_24185", "title": "[Migratory hyperdense posterior cerebral artery sign following intravenous thrombolysis].", "score": 0.008849557522123894, "content": "Computed tomography (CT) scanning of the brain continues to be the basic imaging mode in the acute phase of stroke.

Such hemorrhage usually occurs within or at the margin of ischemic or manifestly infarcted brain tissue. A patient with Trousseau syndrome who developed multiple extra-ischemic hemorrhages following intravenous thrombolysis is described. An 80-year-old Japanese man with no other underlying disease was diagnosed with unresectable advanced lung cancer (stage IV) without brain metastasis and had not yet been treated. The patient suddenly presented with disturbance of consciousness, right hemiplegia, and total aphasia, and was admitted to our hospital. Magnetic resonance imaging revealed acute cerebral infarction extending from the basal ganglia to the corona radiata of the left cerebrum and multiple small areas of bilateral cerebral cortices. Cardiogenic cerebral embolism was considered among the differential diagnoses, but the brain natriuretic peptide level was within the normal range, and no arrhythmias such as atrial fibrillation were observed. With no other causes, the patient was diagnosed with Trousseau syndrome due to hypercoagulability associated with the advanced lung cancer. The patient received intravenous tissue plasminogen activator (t-PA) at 96 minutes after onset of symptoms. His symptoms partially improved, but they suddenly deteriorated at 84 minutes after the thrombolysis. A computed tomography (CT) scan immediately after the neurological deterioration revealed a subcortical hemorrhage in the left occipital lobe. A repeat CT scan the day after onset showed enlargement of the left occipital hemorrhage and two new subcortical hemorrhages in the right frontal and right temporal lobes. These hemorrhages were located in areas remote from the acute ischemic lesions. To the best of our knowledge, this is the first reported case of multiple extra-ischemic hemorrhages following intravenous thrombolysis in a patient with Trousseau syndrome. The course of this case suggests that intravenous t-PA administration for acute ischemic stroke with Trousseau syndrome may be associated with a higher risk of intracranial hemorrhage." } ] } } }

Extragenital germ cell tumors can also occur in the mediastinum or the pineal gland. The aim of this paper is to outline the particularities and draw embryological, histopatological and treatment conclusions regarding extragonadal germ cell tumors. A 43-year-old patient without any additional pathology was admitted for anemia of unknown etiology. The clinical examination revealed through deep abdominal palpation a mass in the left flank, and normal testes. Thoraco-abdomino-pelvic computed tomography (CT) scan showed a large retroperitoneal tumor adjacent to the great vessels in the left lumbo-iliac region. The blood work revealed just a low hemoglobin and hematocrit. With the established diagnosis of retroperitoneal tumor, radical surgical removal was decided. During the surgery, we were required to dissect a large solid encapsulated tumor mass from the aorta and the common iliac artery, starting at the renal pedicle all the way to the left iliac bifurcation. The surgical access was obtained through a transperitoneal left subcostal incision prolonged pararectally. Histopathological and immunohistochemical studies revealed a seminoma of the usual type. After the histological findings, the patient's tumor markers were investigated (LDH - lactate dehydrogenase, βHCG - beta-human chorionic gonadotropin, αFP - alpha-fetoprotein), all values being within normal ranges. In addition, the left testicle was thoroughly reexamined, clinically, through ultrasound and magnetic resonance imaging (MRI) scans, and no abnormalities were observed. After the surgery, the patient followed three courses of chemotherapy (BEP - Bleomycin, Etoposide and Cisplatin). The CT scan done 24 months after surgery found no signs of local or distant tumor recurrence. The patient entered a follow-up schedule consisting of periodical clinical, serological and imagistic evaluations. Primary retroperitoneal seminoma is a rare entity that must be taken into account when treating a retroperitoneal tumor. It develops out of the urogenital ridge, while the testes are normal. Thorough testicular evaluation (clinical, ultrasound and serum markers) is mandatory in all retroperitoneal tumors. The histopathological analysis is crucial for an accurate diagnosis and a proper management strategy.

In all three cases, the patients were males aged in their 30s and 40s who were brought to medical attention for back and lower abdominal pain of varying duration. Initial imaging evaluation with computed tomography and/or ultrasound revealed large abdominopelvic soft tissue masses, with lymphoproliferative disorders or soft tissue sarcomas being high on the list of differential diagnoses. As such, they were referred for staging FDG-PET/CT, all of whom demonstrated the pathognomonic constellation of, 1) unilateral absence of scrotal testicular activity, and 2) FDG-avid nodal masses along the typical testicular lymphatic drainage pathway. These characteristic patterns were corroborated by a targeted clinical history and examination which revealed a history of cryptorchidism, and elevated β-hCG in two of three patients.

These cases highlight the importance of clinical history and examination for the clinician, as well as a sound knowledge of the typical testicular lymphatic drainage pathway for the PET physician, which would assist with prompt recognition of the characteristic imaging patterns on FDG-PET/CT.

All patients were operated because of FNAB result \"suspicious for follicular neoplasm\" of thyroid gland at a single institution from January 2016 until March 2020. From this set, six specific categories were defined and the clinical records for patients were collected: sex, age, presence of oxyphilic cells, diameter of the tumour, presence of Hashimoto disease, aggregate amount of clinical and ultrasonographic features of malignancy according to ATA. Results: In 18 patients (16,3%) thyroid cancer occurred. Most frequent subtype turned out to be papillary cancer (66,6%).

In line with this concept, fine-needle aspiration cytology (FNAC) also assigns a benign connotation to the presence of macrofollicular structures, unless thyrocytes present papillary thyroid carcinoma (PTC)-related nuclear features that raise the possibility of a macrofollicular variant of PTC. However, cases showing macrofollicular architecture, capsular invasion, and no PTC features can also be observed. <b<iMethods:</i</b We describe the clinical, cytological, histological, and molecular genetic features of four cases of encapsulated follicular neoplasms that presented histologically with a predominant (&gt;70%) macrofollicular architecture, but which also showed clear signs of capsular invasion, and thus were classified as macrofollicular variant of follicular thyroid carcinoma (MV-FTC). <b<iResults:</i</b Cytologically, macrofollicular structures were identified in all cases, leading to a benign FNAC diagnosis in three of the four cases.

From the outset, this interpretive category was intended to convey a set of differential diagnoses rather than a precise diagnosis, as key diagnostic features, such as capsular and vascular invasion, were not detectable on cytology preparations. Cytologic-histologic correlation studies over the past several decades have shown that FN interpretation can be applied to the spectrum of nonneoplastic tumors to carcinomas. Most tumors classified as FN include follicular adenoma, follicular carcinoma, noninvasive follicular thyroid tumor with papillary-like nuclear features, and follicular variant of papillary thyroid carcinoma. Less common entities that may be classified as FN on FNA include hyalinizing trabecular tumor (HTT), poorly differentiated thyroid carcinoma, medullary carcinoma, and nonthyroidal lesions such as parathyroid tissue, paraganglioma, and metastatic tumors. Advances in our ability to detect characteristic molecular alterations (eg, GLIS gene rearrangements for hyalinizing trabecular tumor) in FNA samples may assist in the identification of some of these entities.

The radiological study of the sella turcica, including in all cases hypocycloidal tomograms, allowed classification of the patients into 3 groups: group I (n = 4) had a grossly enlarged sella turcica, group II (n = 12) had localized alterations indicating the probable existence of a prolactin-secreting microadenoma (\"microdeformation\") while group III patients presented no radiological abnormality. Before treatment, all the patients were submitted to a complete evaluation of the function of their anterior pituitary, including the LH and FSH responses to iv administration of Gn-RH. All the group I patients had low basal LH levels and a blunted response to Gn-RH. The basal LH and in response to Gn-RH were normal in most of the group II patients and in all of the group III patients. An exaggerated FSH response to Gn-RH was observed in 6/12 patients with microdeformation (group II) but not in groups I and III patients. A low LH and a blunted LH response to Gn-RH is highly suggestive of the existence of a pituitary prolactin-secreting adenoma in case of amenorrhoea and hyper-prolactinaemia patients; a normal response does not however rule out such a diagnosis. The reasons for a exaggerated FSH response to Gn-RH in patients with suspected prolactin-secreting microadenoma remain to be investigated though this pattern can also occur in other cases of amenorrhoea. Hence the Gn-RH test might contribute to the assessment of the hypothalamo-pituitary axis of patients with hyper-prolactinaemia. Six patients treated for 4 months with bromocriptine (CB-154) were submitted to re-evaluation of their pituitary gonadotrophins reserve. All the women experienced restoration of menses with 39 days of treatment and the male patient regained potency. It was observed that bromocriptine treatment and subsequent normalized prolactin levels in the 4 group II women tested were associated with normalization of their previously exaggerated FSH response to Gn-RH; LH responses were also diminished in these cases. These data are compatible with the hypothesis that hyper-prolactinaemia per se could interfere with the endogenous secretion of Gn-RH at the hypothalamic level. In one patient with grossly enlarged sella turcica and a previous lack of an LH and FSH response to Gn-RH, bromocriptine treatment restored a normal gonadotrophins response, confirming that, in this case, the alteration of this response was indeed due to a prolonged lack of endogenous Gn-RH secretion." }, { "id": "pubmed23n0130_16090", "title": "[The effects of bromocriptine on anovulatory patients with high LH and euprolactinemia].", "score": 0.014664664664664664, "content": "It is well known that an acute administration of Bromocriptine (dopamine agonist) suppresses the serum LH level either in normal women or in women with polycystic ovary syndrome, in whom the serum LH level is elevated.

Endocrine profile ruled out anovulation of other origin. INTERVENTIONS -- After a control period of 30 days, seven women (group 1) received daily oral bromocriptine (2.5-10.0 mg/day) continuously during two consecutive 30-day periods (T-1 and T-2), and seven women (group 2) received oral bromocriptine only from day 1 to 15 of each 30-day period of treatment.

In men, the combination of low LH and FSH in combination with a low testosterone confirms LH/FSH deficiency; a high testosterone would indicate a source elsewhere in the body (such as a testosterone-secreting tumor). In women, the diagnosis of LH/FSH deficiency depends on whether the woman has been through the menopause. Before the menopause, abnormal menstrual periods together with low estradiol and LH/FSH levels confirm a pituitary problem; after the menopause (when LH/FSH levels are normally elevated and the ovaries produce less estradiol), inappropriately low LH/FSH alone is sufficient.

Six men with hypogonadotropic hypogonadism were treated with physiological doses of GnRH (5 micrograms every 2 h, sc by automatic infusion pump) for 6 weeks. Once their gonadotropin levels were normal, the men received a supraphysiological dosage of T enanthate (200 mg, im, weekly for 8 weeks) in addition to GnRH.

Circulating testosterone concentration and clinical response were evaluated after 3 days, 4 weeks and 6 months of intramuscular administration of human chorionic gonadotropin (HCG) (2500 U/m2/dose). Thalassaemic boys had significantly lower circulating concentrations of testosterone compared to those with constitutional delay of growth and sexual maturation (CSS) at the same pubertal stage. Short- and long-term testosterone response to administrations of HCG was markedly decreased in thalassaemic boys. After 6 months of HCG administration 50 per cent (5/10) of the boys did not show significant testicular enlargement or genital changes.

Our objective was to determine the normal relationship between sleep-related pubertal hormone levels and pituitary-testicular responsiveness to a GnRH agonist (GnRHag) test across the pubertal transition. DESIGN/SETTING AND PARTICIPANTS: We conducted a prospective study in a General Clinical Research Center with healthy 9- to 15-yr-old volunteer boys. INTERVENTIONS included overnight blood sampling followed by leuprolide acetate injection (10 μg/kg). LH, FSH, and testosterone levels were evaluated. LH levels during sleep and post-GnRHag rose steadily during the late prepubertal years. Sleep peak LH correlated highly with the LH response to GnRHag across groups (r = 0.913). A sleep peak LH level of at least 3.7 U/liter predicted pubertal testicular activation with 100% accuracy. LH of at least 14.8 and at least 19.0 U/liter 4 h after GnRHag, respectively, predicted puberty with 100% sensitivity/94% specificity and 100% specificity/94% sensitivity. Overweight pubertal boys had transiently prolonged responses to GnRHag. FSH rose during both waking and sleeping hours during the prepubertal years, and all pubertal boys had an FSH level of at least 0.9 U/liter awake and at least 1.2 U/liter asleep. Sleep LH was more closely related than FSH to testicular size. These data suggest that a critical LH level during sleep (≥3.7 U/liter) heralds the onset of pubertal virilization and that this level is predictable by LH of at least 14.8-19 U/liter 4 h after GnRHag. These data also suggest that LH stimulation of testicular androgen production plays a role in stimulating testicular tubule growth once a critical level of FSH is achieved." }, { "id": "pubmed23n0225_11278", "title": "[Increased and prolonged release of lh and fsh on intravenous administration of a synthetic analogue of lh-rh [d-ser(tbu)6-ea10-lh-rh] in healthy men of various age groups (author's transl)].", "score": 0.009615384615384616, "content": "Healthy male subjects of various age groups respond to the administration of D-Ser(TBU)6-EA10-LH-RH, an analogue of LH-RH substituted in positions 6 and 10, by a prolonged and increased release of LH and FSH.

For unknown reasons, however, some men fail to achieve azoospermia with such regimens. We hypothesized that either 1) daily circulating serum fluoroimmunoreactive gonadotropins were higher or testosterone levels were lower during the weekly injection interval, or 2) monthly circulating bioactive gonadotropin levels were higher in nonazoospermic men. We therefore analyzed daily testosterone and fluoroimmunoreactive gonadotropin levels as well as pooled monthly bioactive and fluoroimmunoreactive gonadotropin levels in normal men receiving chronic TE injections and correlated these levels with sperm production. After a 3-month control period, 51 normal men were randomly assigned to receive intramuscular TE at 25 mg (n = 10), 50 mg (n = 9), 100 mg (n = 10), 300 mg (n = 10), or placebo (n = 12) weekly for 6 months.

In addition, fluoroimmunoreactive and bioactive FSH and LH levels were measured in pooled monthly blood samples drawn just before the next TE injection. In the 100-mg and 300-mg TE groups, mean monthly fluoroimmunoreactive FSH and LH levels were suppressed by 86%-97%, bioactive FSH and LH levels by 62%-80%, and roughly half the subjects became azoospermic. In the 1-week period of month 6, daily testosterone levels between TE injections were within the normal range in men receiving placebo, or 25 or 50 mg of weekly TE, but were significantly elevated in men receiving 100 or 300 mg of weekly TE. At no point during treatment, however, were there significant differences in daily testosterone or fluoroimmunoreactive gonadotropin levels, or monthly bioactive gonadotropin levels between men achieving azoospermia and those with persistent spermatogenesis. This study, therefore, demonstrates that neither monthly nor daily differences in serum testosterone, or fluoroimmunoreactive or bioactive gonadotropins explain why some men fail to completely suppress their sperm counts to zero with weekly TE administration. Innate differences in the testicle's ability to maintain spermatogenesis in a low-gonadotropin environment may explain persistent spermatogenesis in some men treated with androgen-based contraceptive regimens." }, { "id": "pubmed23n0117_15714", "title": "Further acquisitions on gonadal function in bromocriptine treated hyperprolactinemic male patients.", "score": 0.009523809523809525, "content": "The diurnal variation of plasma total and free testosterone (tT and fT) and the gonadotropinemic response to LH-RH were evaluated in a group of hyperprolactinemic impotent males with pituitary microprolactinoma before and during therapy with bromocriptine, a well known dopamine agonist drug.

We reviewed the cases to extract patient and clinical characteristics and time from triage until diagnosis and start of treatment. The findings were compared with recommendations in clinical practice guidelines. We identified 49 episodes of diabetic ketoacidosis (4 mild, 32 moderate, and 13 severe) in 43 patients. The median delay between triage until the first blood test results were available was 142 minutes (range, 59-597 minutes). In 50% of the cases fluid therapy was delayed beyond the time recommended in clinical practice guidelines. Intravenous insulin was also delayed (in 66%) and insuficient intravenous potassium was given in 65%. Sodium bicarbonate was overused (in 50%).

Thirty-three children presenting to an urban pediatric emergency department in DKA were randomized into 2 groups: patients managed with the two-bag system and patients managed with the traditional \"one-bag'' system. Other aspects of the management were standardized. Outcome measures included rate of decline in serum glucose, rate of bicarbonate correction, time on IV insulin therapy, and response time for IV fluid changes. Study period was defined as time on IV insulin therapy. There were no differences between the 2 groups in demographic parameters, initial baseline metabolic parameters, or total time on IV insulin therapy. There were no differences between the groups in average rates of serum glucose decline: two-bag 33.1 mg/dL/hr (s.e. 5.57, 95% CI 22.2, 44), one-bag 30.2 mg/dL/hr (s.e. 5.72, 95% CI 19, 41.4); average rate of serum bicarbonate correction: two-bag 1.19 mEq/L/hr, one-bag 1.27 mEq/L/hr; or the average number of IV fluid bags used: two-bag 4.1 bags, one-bag 3.2 bags.

Simultaneous administration of sodium bicarbonate and insulin with glucose was compared with infusion of either bicarbonate alone or insulin and glucose. Plasma potassium was measured at the baseline and after 60 min of infusion with each regimen. Infusion of 8.4% solution of sodium bicarbonate at 2 mEq/min for 60 min induced a significant rise in blood bicarbonate from 21.7 +/- 2.1 to 26.3 +/- 1.7 mEq/l (p &lt; 0.01), but failed to lower plasma potassium (6.4 +/- 0.1 vs. 6.3 +/- 0.2 mEq/l, before and after). Intravenous infusion of insulin and glucose (5 mU/kg/min for 60 min) significantly lowered plasma potassium from 6.3 +/- 0.1 to 5.7 +/- 0.1 mEq/l (p &lt; 0.01). The combined infusion of bicarbonate and insulin with glucose showed the greatest decline in plasma potassium, from 6.2 +/- 0.2 to 5.2 +/- 0.1 mEq/l (p &lt; 0.01).

This was a prospective, interventional study conducted from the ED of an urban, university-affiliated hospital. All subjects were healthy employee volunteers between 25 and 40 years of age. Baseline serum glucose levels were determined and all subjects were given an i.v. bolus of 25 grams of 50% dextrose solution. The main outcome measures were post-D50W serum glucose levels (observed) at 5 predetermined time intervals (5 min, 15 min, 30 min, 1 hr, and 2 hr). An expected change in serum glucose was calculated using the volume of distribution formula for glucose. Twenty-five volunteers (17 males and 8 females) participated in the study. The mean baseline serum glucose was 82.3 +/- 13.5 mg/dL. The mean post-infusion levels were: 244.4 +/- 44.6 mg/dL (5 min), 145.8 +/- 52.3 mg/dL (15 min), 88.1 +/- 28.8 mg/dL (30 min), 77.6 +/- 13.6 mg/dL (60 min), and 83.2 +/- 11.4 mg/dL (120 min).

The expected change based on the volume of distribution formula (53.7 +/- 34.9) did not correlate with the observed changes at any measured time interval. Without pre-intervention blood drawing by emergency medical services, it is not possible to accurately predict pre-D50W serum glucose levels based on post-D50W glucose levels. The diagnosis of hypoglycemia as the etiology of altered mental status must therefore remain a diagnosis of exclusion.

T2DM is associated with 2-4 times higher risk for cardiovascular disease (CVD), including coronary artery disease, stroke and peripheral vascular disease. Several studies have shown the benefit of intensive glycaemic control in reducing the frequency of diabetic microvascular complications such as retinopathy and nephropathy. Results of long term follow up of patients with diabetes, who were enrolled in earlier trials, have shown that initial intensive glycaemic control led to a reduction in CVD outcomes when compared with standard therapy. However, it is unclear if intensive glycaemic control, aiming to reduce haemoglobin A1c to levels even lower than the current goal of &lt;7%, will similarly lead to reduction in the rates of CVD. Recently, the results of 3 large, randomized controlled trials have been published, which suggest that in established T2DM with previous CVD or high risk of CVD, the benefits of intensive glycaemic control when compared with conventional good control, are minimal with regards to reduction of cardiovascular outcomes. Intensive therapy increases the risk of side-effects such as severe hypoglycaemia and weight gain. The implementation of such a therapy, with rigorous attention to frequent monitoring of blood glucose and visits to the physician, is not likely to be possible on a large scale, especially in a developing country such as India. The aim of management of patients with established T2DM should be to achieve the goal of good glycaemic control (haemoglobin A1c&lt;7%), with avoidance of hypoglycaemia. It is equally, if not more important, to control other risk factors of CVD by paying greater attention to lifestyle measures (weight loss if overweight or obese, regular exercise, cessation of smoking), rigorous control of blood pressure (&lt;130/80 mmHg) and low density lipoprotein (LDL) cholesterol (&lt;100 mg/dl or &lt;70 mg/dl if already diagnosed with CVD) and the prophylactic use of low dose aspirin as per current recommendations.

We identified randomized clinical trials that addressed selected aspects of the care of adults with type 2 diabetes using systematic literature review, review of existing clinical guidelines, and other sources. The results of these trials were interpreted as absolute risk reduction, and the number of patients that need to be treated to obtain a specific clinical outcome was calculated. Good glycemic control with metformin may reduce overall mortality in obese patients with type 2 diabetes (number need to treat [NNT] = 14 for 10 years), and improved blood pressure control reduced diabetes-related mortality (NNT = 15 for 10 years); improved glycemic control with agents other than metformin, or with combinations including metformin, does not reduce diabetes-related or overall mortality. Major cardiovascular events (CVE) in type 2 diabetes can be prevented by control of blood pressure with low-dose diuretics, atenolol, or angiotensin-converting enzyme inhibitors (NNT = 10 to 20 for 5 to 10 years for primary prevention of one CVE); by use of aspirin (NNT = 45 for 5 years for primary prevention of one CVE); and by use of simvastatin to lower low-density lipoprotein (LDL) cholesterol (NNT = 6 for 5 years for secondary prevention of one CVE). Glycemic control (NNT = 19 for 10 years) and hypertension control (NNT = 6 for 10 years) slow the progression of complications in patients with type 2 diabetes. Retinopathy and nephropathy are more preventable than neuropathy. The benefits of glycemic control are less for patients with shorter life expectancy and are greater for those with the highest levels of Hb A1c because larger Hb A1c improvements can be achieved in such patients. Periodic screening of patients for eye, kidney, and foot complications is supported because effective early treatment of these complications is available. In patients with type 2 diabetes, control of hypertension reduces microvascular and macrovascular complications more than glycemic control does. Control of LDL cholesterol with statins, aspirin, and smoking cessation reduce major cardiovascular events. Metformin reduces overall mortality in obese patients with creatinine levels &lt; 1.5 mg/dL. Glycemic control reduces microvascular complications. The evidence supports angiotensin-converting enzyme inhibitors, atenolol, or low-dose diuretics for blood pressure control.

Benefits.", "score": 0.015189158667419538, "content": "The underlying disorder in the vast majority of cases of cardiovascular disease (CVD) is atherosclerosis, for which low-density lipoprotein cholesterol (LDL-C) is recognized as the first and foremost risk factor. HMG-CoA reductase inhibitors, popularly called statins, are highly effective and remarkably safe in reducing LDL-C and non-HDL-C levels. Evidence from clinical trials have demonstrated that statin therapy can reduce the risk of myocardial infarction (MI), stroke, death, and the need for coronary artery revascularization procedures (CARPs) by 25-50%, depending on the magnitude of LDL-C lowering achieved. Benefits are seen in men and women, young and old, and in people with and without diabetes or prior diagnosis of CVD. Clinical trials comparing standard statin therapy to intensive statin therapy have clearly demonstrated greater benefits in CVD risk reduction (including halting the progression and even reversing coronary atherosclerosis) without any corresponding increase in risk. Numerous outcome trials of intensive statin therapy using atorvastatin 80 mg/d have demonstrated the safety and the benefits of lowering LDL-C to very low levels. This led the USNCEP Guideline Committee to standardize 40 mg/dL as the optimum LDL-C level, above which the CVD risk begins to rise. Recent studies have shown intensive statin therapy can also lower CVD events even in low-risk individuals with LDL-C &lt;110 mg/dL. Because of the heightened risk of CVD in Asian Indians, the LDL-C target is set at 30 mg/dL lower than that recommended by NCEP. Accordingly, the LDL-C goal is &lt; 70 mg/dL for Indians who have CVD, diabetes, metabolic syndrome, or chronic kidney disease. Intensive statin therapy is often required in these populations as well as others who require a &gt; or = 50% reduction in LDL-C. Broader acceptance of this lower LDL-C targets and its implementation could reduce the CVD burden in the Indian population by 50% in the next 25 years. Clinical trial data support an extremely favorable benefit-to-risk ratio of intensive statin therapy with some but not all statins. Atorvastatin 80 mg/d is 100 times safer than aspirin 81 mg/d and 10 times safer than diabetic medications.

Given the coronary plaque burden over many years and the importance of the development of healthy lifestyles early in adulthood to decrease coronary plaque burden, there are excellent reasons to begin prevention even with young adults. At the very least, a patient seen for any reason should provide a smoking history, have knowledge of the presence of early CHD in first-degree relatives and measurements of blood pressure, height, and weight, provide evidence for a cholesterol level within 5 years (after age 20 according to NCEP guidelines or in middle age according to ACP guidelines), and be given an assessment of glucose tolerance or diabetes. Information about alcohol intake and physical activity status are also of some importance. Other than height, weight, and blood pressure, during the physical examination, the physician should initially assess the strength of pulses in the lower extremities, evidence for carotid or femoral bruits, and eyegrounds for retinal arterial changes, and the skin and subcutaneous tissue should be examined for xanthomas and the eyes should be examined for corneal arcus and xanthelesma. These elements should be part of any initial examination by a primary care physician and are not extraordinary.

The key interventions aim at the lowering of blood pressure to at least less than 140/90 mm Hg, the complete cessation of smoking, the lowering of lipid levels to less than 130 mg/dL, the lowering of triglycerides to less than 200 mg/dL (or, some would argue, &lt; 150 mg/dL), and the attempt to keep HDL cholesterol above 35 mg/dL (more than 40 to 45 mg/dL is a better goal) with the use of lifestyle modification. For patients with diabetes, strict control of glucose levels is essential to minimize disease of the microvasculature and possibly to minimize progressive renal disease. There are several lifestyle modifications for lipids. For patients with elevated LDL cholesterol, modifications include a less than 30% fat calorie diet and less than 300 mg of cholesterol intake daily, with fat calories approximately equally distributed among saturated fats, polyunsaturated fats, and monounsaturated fats (1/3, 1/3, 1/3; rule of 3s). The assistance of a dietician is extremely helpful in this regard. For patients with a low HDL cholesterol, weight reduction (for overweight patients) by calorie control and increased physical activity and smoking cessation will have some modest effect. For patients with elevated triglycerides, a diet similar to that for lowering of LDL cholesterol with the addition of stricter calorie limitation, avoidance of refined sugars, increase in complex carbohydrates, and avoidance of alcohol will be helpful. A decrease in the percent of fat calories to 20% to 25% will be of assistance to those patients with particularly high triglycerides. The treatment of underlying conditions such as diabetes mellitus, hypothyroidism, liver disease, and some renal conditions may also significantly modify high triglycerides. For patients with hypertension, limitation of sodium to 2 gm/d (6 gm sodium chloride), limitation of alcohol to 1 to 2 drinks a day, increased physical activity, and weight reduction are the key lifestyle modifications.

The presence of DM confers these individuals the same risk of having a coronary event as present in a non-diabetic person who has suffered a previous myocardial infarction. Arterial hypertension, a characteristic dyslipidaemia (hypertrigliceridemia, low level of high density lipoprotein cholesterol and elevated low density lipoprotein cholesterol), obesity, microalbuminuria, platelet hyperaggregability and endothelial dysfunction converge conferring the women with DM a higher susceptibility to atherosclerosis.

Smoking cessation translates into a reduction in overall mortality and morbidity rates at least equal to that of other preventive measures such as aspirin or beta-blocker therapy.

The results among the 3577 diabetic subjects were even more striking, with a reduction of 25% in the combined primary endpoint. This reduction in the combined endpoint and in particular the reduction in MI far exceeded that which would be expected from the modest fall in BP. Furthermore, a multiple regression analysis of the diabetic subgroup showed similar relative risk reductions even after allowing for the effects of the fall in BP. Possible explanations for the non BP-mediated benefits of ramipril include reduction of angiotensin II-induced intimal and vascular smooth muscle proliferation and possible plaque stabilisation. The HOPE study results show that it is both safe and beneficial to lower BP that is already within the 'normal' range, particularly in patients with known vascular risk factors.

However, no trial of cholesterol-lowering therapy has been completed in stroke patients. A strict control of high cholesterol levels should be encouraged, because of benefits in terms of CHD. Statins should be prescribed for stroke patients with CHD, or increased cholesterol levels. Cigarette smoking is associated with an increased risk of stroke and should be avoided. Careful control of all risk factors, especially arterial hypertension in type 1 and type 2 diabetics is recommended, together with a strict glycemic control to reduce systemic microvascular complications. Estrogens prescribed in hormone replacement or oral contraceptive therapies are not recommended after an ischemic stroke. It is also recommended to reduce alcohol consumption and obesity, and to increase physical activity in patients at risk for first-ever or recurrent stroke. An optimal management of risk factors for stroke is crucial to reduce the risks of first-ever stroke, recurrent stroke, any vascular event after stroke and vascular death. One of the major public health issues for the coming years will be to focus more on risk factor recognition and management." }, { "id": "wiki20220301en008_126427", "title": "Type 2 diabetes", "score": 0.009013134995511752, "content": "Management of type 2 diabetes focuses on lifestyle interventions, lowering other cardiovascular risk factors, and maintaining blood glucose levels in the normal range. Self-monitoring of blood glucose for people with newly diagnosed type 2 diabetes may be used in combination with education, although the benefit of self-monitoring in those not using multi-dose insulin is questionable. In those who do not want to measure blood levels, measuring urine levels may be done. Managing other cardiovascular risk factors, such as hypertension, high cholesterol, and microalbuminuria, improves a person's life expectancy. Decreasing the systolic blood pressure to less than 140 mmHg is associated with a lower risk of death and better outcomes.

At the Charles George Veterans Affairs Medical Center (CGVAMC), physicians may refer their patients to the on-site pharmacist-managed Risk Reduction Clinic (RRC). Patients are discharged from the RRC once patient-specific therapeutic goals have been met for diabetes, dyslipidemia, and/or hypertension. This study investigated the change in A1c, LDL, and systolic blood pressure (SBP) after discharge from the CGVAMC RRC. To investigate (a) how clinical endpoints for diabetes, dyslipidemia, and hypertension change after discharge from the pharmacist-managed RRC at the CGVAMC; (b) the factors associated with worsening of monitoring parameters; and (c) the frequency of reconsultation to the RRC. In this single-center retrospective quality management study, patients were included if they had a completed consultation to the CGVAMC RRC between August 11, 2008, and January 1, 2011, for the management of type 2 diabetes, dyslipidemia, and/or hypertension. Patients were included if they were discharged from the RRC prior to October 1, 2011, due to goal attainment. Furthermore, it was required that patients have A1c, LDL, and SBP measurements, as applicable based on diagnoses, at least yearly during the first 2 years following discharge. Patients were excluded if they were discharged for any reason other than goal attainment or if they were followed by a specialty clinic related to the RRC, including the Diabetes PharmD, Diabetes MD, MIDAS (group diabetes), or MAGIC (group dyslipidemia) clinics. Data collection included patient demographics; date of and indication for consultation to the RRC; date of first RRC visit; date of discharge from the RRC; number of visits to the RRC; A1c, LDL, SBP, and weight at consultation to the RRC, at discharge, and during the 2 years following discharge from the RRC; and date of and indication for reconsultation to the RRC, as applicable. Two-tailed paired t-tests were used to compare A1c, LDL, and SBP at discharge from the RRC to A1c, LDL, and SBP during the follow-up period. Two-tailed unpaired t-tests were performed to determine which variables were associated with changes in the monitoring parameters after discharge from the RRC. One hundred forty-nine patients were included in this study. For all patients with a diagnosis of diabetes (N = 82), A1c rose from 6.49% to 6.79% (P &lt; 0.001) during the first year and to 7.04% (P &lt; 0.001) during the second year following discharge. For patients diagnosed with dyslipidemia (N = 137), LDL rose after discharge from 81.5 mg/dL to 90.8 mg/dL (P &lt; 0.001) and to 90.9 mg/dL (P &lt; 0.001), respectively. For patients diagnosed with hypertension (N = 132), SBP rose from 126.2 mm Hg to 131.5 mm Hg (P &lt; 0.001) and to 133.9 mm Hg (P &lt; 0.001), respectively. An increase in A1c after discharge was associated with lower discharge A1c (P = 0.014), higher consultation weight (P = 0.009), and higher discharge weight (P = 0.042). A rise in LDL was correlated to higher consultation LDL (P = 0.006), while higher SBP was associated with lower discharge SBP (P &lt; 0.001). Twelve percent of patients were reconsulted to the RRC. A1c, LDL, and SBP rose after discharge from the pharmacist-managed risk reduction clinic, but these changes may not have been clinically significant based on the low reconsultation rate and values remaining close to generally accepted therapeutic goals. Patients likely to benefit from extending RRC services past goal attainment include those with higher A1c and LDL at the time of consultation and those with higher weight. As a result of this study, recommendations have been made to consider following up every 3-4 months for 2-3 additional visits for patients with baseline A1c &gt; 8% and LDL &gt; 115 mg/dL and those with weight &gt; 220 pounds prior to discharging them from the CGVAMC RRC.

The term includes impaired glucose homeostasis (impaired fasting glucose and impaired glucose tolerance) and type 2 diabetes mellitus. Although glycaemic control has been shown to lower the risk of microvascular events, the effect of intensive glycaemic control on macrovascular outcomes is less clear. Epidemiological studies show hyperglycaemia, particularly the postprandial one, to be a clear risk factor for cardiovascular (CV) mortality and morbidity. However, the intervention studies are less conclusive. The large interventional studies published in 2008 and 2009 (UKPDS, VADT, ACCORD, ADVANCE, RECORD) advocate the controlling of nonglycemic risk factors (through blood pressure control, lipid lowering with statin therapy, aspirin therapy, and lifestyle modifications) as the primary strategies for reducing the burden of CV disease in people with diabetes, and demonstrated the need for individualized approach to the patients' care in terms of blood glucose control. The patients with shorter duration of type 2 diabetes and without established atherosclerosis might reap CV benefit from intensive glycemic control. Conversely, it is possible that potential risks of intensive glycaemic control (hypoglycaemia) may outweigh its benefits in other patients, such as those with a very long duration ofdiabetes, known history of severe hypoglycemia, advanced atherosclerosis, and advanced age/frailty. According to the latest recommendations of the Czech Diabetes Society that are in line with the European and US standards the best way to protect type 2 diabetic patients against coronary and cerebrovascular disease is to target all cardiovascular risk factors (blood pressure treatment, including lipid-lowering with statins, aspirin prophylaxis, smoking cessation, and healthy lifestyle behaviors hypertension, dyslipidemia, obesity and other symptoms of metabolic syndrome. The target HbA1c levels in patients with the low CV risk shoul be below 4.5%. Less strict goals (HbA1c below 6%) may be appropriate for patients with a history of severe hypoglycemia, limited life expectancy, advanced microvascular or macrovascular complications, or extensive comorbid conditions or those with long-standing diabetes. The individual targets should be achieved safely (without hypoglycaemias). Slow advancing in diabetes compensation is preferred. Lifestyle changes are the cornerstone of therapy. Metformin is the drug of choice; its administration, together with lifestyle changes, should be initiated immediately after the diagnoses of diabetes. If monotherapy does not provide satisfactory glucose control, other oral antidiabetic agents or insulin are added to the combination. Since it is not known which hypoglycaemic agents are beneficial from the perspective of long-term patient prognosis, the selection is liberal. Contraindication of the various farmaceuticals must be respected. It is possible to use a range of different combinations, metformin is administered with a glitazone (zero risk of hypoglycaemias is the advantage) with sulphonylurea derivatives (low price is the advantage) with glinides, with incretins, acarbose, antiobesity agents or insulin. The next step is a triple combination of hypoglycaemic agents with different mechanisms of action. Therapy also includes education focusing on changes to dietary and lifestyle habits, including smoking cessation, and education related to the prevention of complications, with particular regard to prevention of diabetic foot and atherosclerosis." }, { "id": "pubmed23n0565_6136", "title": "[The best of epidemiology and cardiovascular prevention in 2006].", "score": 0.008928571428571428, "content": "The recent analysis of the French MONICA registries report a reduction in the incidence of fatal MI related to improvement of care whereas the overall incidence of coronary events remain stable, suggesting the need for a better primary prevention. The extensive review of the death certificates and the analysis of the death classification from the same registries indicate an under estimation of MI-related death in the national death registry. It is also confirmed that instead of 50%, approximately 80% of coronary death are explained by the four major risk factors including smoking, hypercholesterolemia, hypertension and diabetes. The international REACH registry has enrolled more than 67 000 individuals including patients with symptomatic atherothrombotic disease and patients with multiple risk factors. The analysis of baseline characteristics and of the one year FU shows a high residual risk and a lack of efficacy of secondary prevention. The existence of a symptomatic disease and the number of symptomatic localization of atherothrombosis are critical factors to predict recurrence of major vascular events Secondary analysis of the INTERHEART study provide the essence of what should any physician know about the relationship between coronary heart disease and smoking, either active or passive. Prevention with respect to this risk factor remains very insufficient. Varenicline, a new nicotinic receptor partial agonist, should help patients involved in smoking cessation program. The established detrimental effects of perioperative smoking represent a unique opportunity to promote smoking cessation in individuals scheduled for surgery. The major cardiovascular impact of second hand smoking has been recently demonstrated by the short-term effects of banning smoking in public places on the incidence of acute coronary events. The SPARCL study has demonstrated the benefit of high dose of atorvastatine to prevent recurrent acute ischemic cerebrovascular event in patients with a prior history of stroke or TIA. In the open ASTEROID study, high doses of rosuvastatine confirm the possibility of reducing the volume of coronary atheroma analyzed by IVUS. The expected benefit of glitazones to reduce the incidence of death, MI and stroke in diabetes patients with a prior history of vascular event has been confirmed in the PROactive study. Pioglitazone provided a clear reduction of recurrent vascular events in diabetes patient with a prior MI at a cost of a significant increase of the risk of heart failure. In the DREAM study, neither ramipril nor rosiglitazone have reduced the incidence of cardiovascular events significantly. The moderate benefit of the fenofibrate to prevent cardiovascular events in the FIELD study, which was carried out in diabetics mostly in primary prevention, needs to be considered after adjustment on statin use in a higher proportion of patients of the placebo group. Postprandial hyperglycaemia, analyzed by the peak of glycaemia after a load in glucose, has been confirmed as a more powerful independent predictive factor of the risk of cardiovascular event than fasting glycaemia. The systematic screening postprandial hyperglycaemia represents an interesting strategy for primary prevention which warrants further investigation. If obesity is a risk factor whose impact on morbi-mortality is well established, a French study shows that body mass index has an unfavourable influence on the cognitive functions in middle-aged men and women." } ] } } }

Antiretroviral treatment was not routinely available at that time. Of the 42 patients enrolled, 35 (83%) were males. The mean age was 33.2 (SD-6.3) years. Cough was the commonest (67%) presenting symptom and opacities were the commonest (48%) radiographic occurrence. 31 patients were culture-positive at baseline, drug susceptibility results showed that 21 (68%) were fully susceptible to all first line drugs, four patients (13%) had MDR TB and four had resistance to INH alone. Among the 31 culture-positive patients, 15 patients (48.4%) completed treatment and were declared cured, of whom two subsequently relapsed. All four MDR patients died. Six patients who received ART, survived. Only 50% of HIV-infected, ART-naive patients who were retreated for tuberculosis using an intermittent Category II regimen had a favourable response to treatment. Early detection of MDRTB and concurrent antiretroviral therapy could contribute to improved outcomes." }, { "id": "Surgery_Schwartz_4781", "title": "Surgery_Schwartz", "score": 0.009766522658332567, "content": "accuracy.

Prior to initiating treatment, 20 patients were found to be TST positive. All patients had clear chest x-rays and were treated with nine months of INH prior to initiating biologic therapy at least month later.

Numbers of observed resistant failures were compared to numbers expected due to pre-existing resistance. Trends of resistance in combined new and previously treated cases were extrapolated. High drug resistance rates were observed. Changes in resistance to streptomycin, the virtual absence of documented acquired resistance and a close match of observed with expected resistant failures all indicated accumulation of primary drug resistance as the main mechanism. Resistance in relapse/failure cases showed a significantly declining trend, and estimated combined drug resistance decreased rapidly. Drug resistance in previously treated cases seems to consist of passed-on primary rather than true acquired resistance. A one-time survey is thus confusing, but continuous routine testing may constitute the best drug resistance monitoring method. Cases previously treated with short-course chemotherapy may show drug resistance much more frequently than generally assumed, and all should receive a re-treatment regimen. The 2EHRZ/6TH regimen proved very safe under field conditions, causing no 'amplification' towards multidrug resistance and almost no acquired isoniazid resistance.

Symptoms subsided spontaneously in 48 hours and one month later all haematology tests were normal except for minimal alteration of platelet aggregation. Pulmonary oedema in breath hold divers is usually attributed to blood shift to the pulmonary circulation related to the lowered intra-thoracic pressure.

The PO2, PCO2, pH, and HCO3- concentrations in parotid saliva were measured with a Blood Gas Analyzer System. The results are summarized as follows: 1) The mean PO2 and PCO2 of parotid saliva immediately before tongue stimulation were about 40 mmHg (range 33-44 mmHg) and 45 mmHg (41-48). There values were similar to those of venous blood. 2) PO2 increased to about 50 mmHg (46-54) 5 to 10 sec. after stimulation, and then 3 to 8 min. later, it decreased to a minimum value of about 28 mmHg (26-29) before returning to the resting level 15 min. after stimulation, when the intervals between stimulations were longer than 2 min., similar changes in PO2 were observed, whereas stimulations every 30 sec. or 1 min. had no effect on PO2. 3) PCO2 increased to about 98 mmHg (85-120) from the resting level of 45 mmHg (41-48) 5 to 10 sec. after stimulation, and returned to the resting level 1 min. after stimulation. When the intervals between stimulations were shorter than 20 min., the peak value of PCO2 by the first stimulation was higher than those induced by the following stimulations. When the interval was 30 sec. or 1 min., only the peak after the first stimulation was observed. 4) The pH of parotid saliva was about 7.4 (7.35-7.5) 30 to 50 sec. after stimulation, and it decreased below 6.5 about 12 min. after stimulation. When the interval between stimulations was 5 min., the pH of the parotid saliva after stimulation was always above 6.5. When the interval between stimulations was 1 min. or 30 sec., it remained at about 7.5. 5) The HCO3- concentration in parotid saliva depends almost exclusively on the pH when Pco2 remained unchanged. When Pco2 was high, however, the HCO3- concentration was affected by the change in Pco2. 6) There was no relationship between changes in the flow rate of parotid saliva and Po2, Pco2, pH, and the HCO3- concentration.

From day 90 onward, the water was aerated and the turtles were allowed access to the air; water and air temperatures were maintained at 3 degrees C. Arterial blood samples were taken periodically and analysed for PO2, PCO2, pH, [Na+], [K+] [Cl-], [lactate-], [glucose] and haematocrit. Plasma [HCO3-] was calculated for all samples and total plasma calcium was measured on samples from two animals. Each exposure to low PO2 water caused progressive lactic acidosis and a transient respiratory acidosis with an accompanying fall in plasma [Cl-] and rise in plasma [K+] and [calcium]. During the intervening period in aerated water, blood pH recovered significantly (from 7.33 to 7.74 in 7 days), due primarily to a fall in PCO2 (from 23.5 to 10.6 mmHg), while [lactate-] remained unchanged (at about 50 mM), and [HCO-3] rose slightly. Plasma [K+] promptly returned to nearly normal values. When permitted to breathe on day 90, the three surviving turtles rapidly restored pH to normal by pronounced hyperventilation (PCO2 less than 5 mmHg). Metabolic acidosis, however, disappeared slowly with a t1/2 for [lactate-] and [HCO-3] restoration of about 2 weeks. We conclude that a wintering turtle can stabilize or even slightly improve its acid-base and ionic status by moving from an anoxic environment to well-oxygenated water. Further improvements can be gained by breathing air, but recovery proceeds at a very slow rate if the animal remains at 3 degrees C." }, { "id": "pubmed23n0001_3535", "title": "[Examinations to phenomenon of shock-lung (author's transl)].", "score": 0.009708737864077669, "content": "The pathogenesis of shock lung as well as the success of therapy in this condition was studied in 79 cases of extrathoracic trauma.

The fluid balance, pO2, pCO2, central venous pressure, pH of the serum, total serum protein and serum creatinine were also studied in these cases. Results of the study are as follows. Three phases of the posttraumatic syndrome of shock-lung could be distinguished: phase I (initial phase): blood perfusion is increased, edema is beginning to form, and medical treatment has not yet begun. Phase II (early phase = sydrome of early respiratory failure): pulmonary edema is developing rapidly while perfusion is decreasing.

Onset of dyspnea, wheezing, chest pain, cyanosis and right heart failure can lead to urgent need for oxygen during flight. The hypoxia inhalation test (HIT) provides a safe and simple means of identifying those who may develop hypoxemia during flight. We report our experience with 48 self-reporting patients who underwent HIT prior to pre-planned air travel. They inhaled for 15-minute periods a reduced oxygen concentration (F1O2 15%) under normobaric conditions, during which O2 saturation was monitored by pulse oximeter; electrocardiogram, blood pressure and symptoms were also monitored. O2 saturation of &lt; 85% (PaO2 50 mm Hg) was considered a positive test. In the 8 cases (17%) with a positive test, 5 had chronic obstructive pulmonary disease and 3 had cardiovascular and/or combined heart-lung disease. We calculated predicted O2 partial pressure in altitude (PaO2ALT) and compared it to actual results in the 8 patients with a positive HIT. In 5, use of the predicted formula would have under-diagnosed the hypoxemia that developed during the HIT. Thus, the results of the HIT changed treatment strategy in these patients. We recommend that patients with positive tests use O2 (2LPM or 4LPM) during flight. HIT is practical and of potential benefit in the objective assessment of patients with various degrees of heart, lung or combined heart-lung disease. Clinicians should be aware of the relative risk of hypoxia during flight in such patients, and of the value of HIT in identifying them, leading to increase in its use." }, { "id": "pubmed23n0525_4588", "title": "Mystery in the basement.", "score": 0.009433962264150943, "content": "56 year-old male presented to the University of Mississippi Medical Center emergency department (ED) with complaints of progressive shortness of breath, productive cough, fever, and malaise.

Version 3 features on-line data collection from the analyser; storage of up to 2000 patient cases in a Lotus 123 file format; printing of a Cumulated Patient Report in addition to the Patient Status Report; combination of arterial and mixed venous data for calculation of the shunt and the oxygen consumption rate (when cardiac output is keyed in); calculation of reference values for fetal haemoglobin for newborns (when gestational age is keyed in). Examples of applications answer the following questions: 1) Does hyperventilation improve the oxygen supply to the tissues? No, for a normal person a slight hypoventilation with a pCO2 of 8.5 kPa provides a maximal oxygen extraction tension. 2) What is the optimal hyperventilation at the top of Mt. Everest (ambient pressure 33 kPa)? Hyperventilation to a pCO2 of about 1.4 kPa provides a maximal oxygen extraction tension of 2.4 kPa for an unacclimatized person. 3) Which change in haemoglobin oxygen affinity would be equivalent to a decrease in arterial pO2 to 6.3 kPa? The oxygen extraction tension would decrease to 4.0 kPa and the same value would be caused by a decrease in half-saturation tension to 2.8 kPa, a decrease which could be due to a moderate alkalaemia (pH = 7.54) combined with a moderately decreased 2,3-diphosphoglycerate concentration (3.4 mmol/L). 4) Is temperature correction of the measured pO2 and pCO2 to the actual body temperature needed? Yes, for example, omitting temperature correction even when the patient temperature is only slightly decreased to 36 degrees C would result in a negative value for the calculated arterio-venous shunt fraction when the actual value, using temperature correction, is 11%. 5) Does the alpha-stat approach of pCO2 and pH regulation in hypothermia, where pH is allowed to rise as in blood in vitro, cause a fall in mixed venous pO2 below the critical value? No, although the mixed venous pO2 will be lower than with the pH-stat approach (constant pH at body temperature), it remains above the critical mixed venous pO2 level.

Half of the patients with FL reported insidious onset of the disease, and 28% reported acute onset. Dyspnoea was reported by all patients, coughing was almost as common. A considerable proportion of the patients reported muscle and joint pains. Diffuse opacities were detected in the chest radiograms of 99 patients (93%): the more severe the radiological change, the more impaired the DLco value. A normal chest radiogram was seen in eight of the 107 patients at the first evaluation. Half of the patients showed a restrictive type of impairment of ventilatory function at the first evaluation.

Case 1: A 49-year-old man with history of mild hypertension presented with recurrent transient ischemic attacks. At the age of 42, evaluation for progressive visual loss and skin changes led to diagnosis of PXE. Brain magnetic resonance imaging (MRI) disclosed multiple lacunar infarctions and confluent periventricular white matter lesions (WML). Case 2: A 71-year-old woman with history of mild hypertension suffered right-sided stroke. Diagnosis of PXE was made at the age of 48 due to severe visual loss and skin changes.

Infarction of the left anterior cerebral artery brings about transcortical motor aphasia. Occlusion of each branches of the left middle cerebral artery produces characteristic language symptoms. Recently, cases with infarction of the areas of prefrontal and precentral arteries were reported to manifest fluent aphasia indistinguishable from the classical transcortical sensory aphasia. Rare cases with lesions restricted to the Broca's area (territory of the precentral artery) produces aphasia with normal fluency, word finding difficulty and deficit in sentence comprehension. Classical non-fluent Broca's aphasia is caused by infarctions which at least involves the areas of precentral and central arteries. Aphemia or pure word dumbness results from damages which involves territory of the central artery. Conduction aphasia is most often associated with lesions of the posterior parietal artery territory. As in the case of Broca's aphasia, Wernicke's aphasia is a composite of conduction aphasia, pure word deafness, transcortical sensory aphasia, and alexia with agraphia. The lesion of Wernicke's aphasia naturally involves the areas of all of these aphasic symptoms. Transcortical sensory aphasia is associated with lesions in the posteroinferior temporal region, and is often associated with watershed infarctions of the middle and posterior cerebral arteries. Aphasia which results from putaminal hemorrhage has ambiguous manifestation, and is difficult to be classified into Wernicke-Lichtheim's model. Assessment of its fluency is notoriously difficult.

When serious ulcer bleeding is suspected and blood found in gastric aspirate, endoscopy within 12 hours will result in faster discharge and reduced need for transfusions. Endoscopic hemostasis remains indicated for high-risk lesions. Clips, thermocoagulation, and epinephrine injection are effective in achieving endoscopic hemostasis. Use of endoscopic monotherapy with epinephrine injection is not recommended. Intravenous high-dose proton pump inhibitor (PPI) therapy for 72 hours after successful endoscopic hemostasis is recommended as it decreases both rebleeding rate and mortality in patients with high-risk stigmata. Although selected patients can be discharged promptly after endoscopy, high-risk patients should be hospitalized for at least 3 days after endoscopic hemostasis. Patients with peptic ulcer bleeding who require secondary cardiovascular prophylaxis should start receiving acetylsalicylic acid (ASA) again as soon as cardiovascular risks outweigh gastrointestinal risks. Patients in need of continued treatment with ASA or a nonsteroidal anti-inflammatory drug should be put on prophylactic treatment with PPI at standard dosage. The combination of 75mg ASA and PPI should be preferred to monotherapy with clopidogrel in patients needing anti-platelet therapy on the basis of indications other than coronary stents." }, { "id": "pubmed23n0643_25160", "title": "[Guidelines of treatment for bleeding peptic ulcer disease].", "score": 0.013621142184813105, "content": "Peptic ulcer (PU) bleeding is the main cause of non-variceal gastrointestinal bleeding. Negative outcomes include re-bleeding and death, and many of the deaths are associated with decompensation of coexisting medical conditions precipitated by acute bleeding event. Accurate analysis of risk for clinical features can help physician to decide treatment modality. Endoscopy can detect bleeding stigmata and perform therapeutic hemostasis. Proton pump inhibitor (PPI) compared with placebo or H2RA reduces mortality following PU bleeding among patients with high-risk endoscopic findings, and reduces re-bleeding rates and surgical intervention. PPI treatment initiated prior to endoscopy in upper gastrointestinal (UGI) bleeding significantly reduces the proportion of patients with stigmata of recent hemorrhage (SRH) at index endoscopy but does not reduce mortality, re-bleeding or the need for surgery. The strategy of giving oral PPI before and after endoscopy, with endoscopic hemostasis for those with major SRH, is likely to be the most cost-effective. The treatment of H. pylori infection was found to be more effective than anti-secretory therapy in preventing recurrent bleeding from PU. H. pylori eradication alone and eradication followed by misoprostol (with switch to PPI, if misoprostol is not tolerated) are the two most cost-effective strategies to prevent ulcer bleeding among H. pylori-infected NSAID users, although the data cannot exclude PPIs also being cost-effective treatment.

All 42 departments responded. All had therapeutic gastroscopes and equipment necessary for endoscopic haemostasis; 90% of departments had written guidelines. Adjuvant pharmacologic treatment included tranexamic acid in 38%. Proton-pump inhibitors (PPIs) were used by all departments, with 29% starting prior to endoscopic treatment. Eight departments (19%) used continuous PPI infusion, three of them starting with a bolus dose. In 50% of departments an anaesthesiologist was always present regardless of whether endotracheal intubation (routinely used by 10%) was used or not. Ten percent did not treat Forrest IIa and IIb ulcers, while IIc ulcers were treated by 36%. In 10% of departments clots were never removed, while in 2/3 attempts were made to remove resistant clots by mechanic means. Seven departments (17%) used monotherapy with epinephrine, while 59% always used dual therapy; 19% injected less than 10 ml. In rebleeding, 92% attempted endoscopic treatment before surgery, and used epinephrine in 79% of cases, while the remainder used epinephrine or polidocanol at the discretion of the endoscopist. Two out of three departments used high-dependency or intensive-care units for surveillance. Seventeen percent applied scheduled second-look gastroscopy. Practice is variable, even in areas with established evidence based on randomized controlled studies, such as dosage and way of administration and duration of PPI treatment, injection treatment used as monotherapy and the volume used, including ulcers with clots for treatment, and the use of scheduled second-look endoscopy. Since the rebleeding rate has remained unchanged for decades, and rebleeding implies increased surgery and mortality rates, appropriate practices must be promoted in order to improve results.

Although the bleeding episode stops spontaneously in most of them, rebleeding occurs in as much as 10-30% of them and has a mortality rate of 5-10%. In this study, we have evaluated the possible significant predictors associated with this adverse outcome. The records of 205 patients admitted to gastrointestinal bleeding unit (GIBU) in Riyadh Central Hospital, during the period May 1996 through to April 1999, with endoscopic confirmed diagnosis of bleeding peptic ulcer disease were reviewed for demography, clinical presentation, hematology, biochemistry, initial blood pressure, nasogastric lavage color, co-morbid disease and endoscopic findings. All the significant factors found initially (P&lt;0.05) were entered into odds ratio and its 95% confidence interval and finally the unconditioned logistic regression model was used to find out the significant independent predictors for both rebleeding and mortality in these patients. The majority of patients (85%) were males and below the age of 60 (73%). Duodenal ulcer was the source of bleeding in 84%. Endoscopy was performed in all patients within 24 hours of admission. Only 15% were actively bleeding at the time of initial endoscopy. Thirty-six patients (17%) rebelled, majority within 72 hours of initial hemostasis. Overall, 11 patients (5%) died, 6 of them were rebleeders. Initial presentation of systolic blood pressure &lt;100 mm Hg, blood in nasogastric tube and visible vessel within the ulcer in endoscopy were independent predictors of rebleeding while initial systolic blood pressure &lt;100 mm Hg and age &gt;60-years were independent predictors of mortality. Improvement of outcome in patients with bleeding peptic ulcer disease can be achieved by early detection of those patients who are at risk of adverse outcome.

It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe or ongoing active UGIH. In selected patients, pre-endoscopic infusion of erythromycin significantly improves endoscopic visualization, reduces the need for second-look endoscopy, decreases the number of units of blood transfused, and reduces duration of hospital stay (strong recommendation, high quality evidence). MR7. Following hemodynamic resuscitation, ESGE recommends early (≤ 24 hours) upper GI endoscopy. Very early (&lt; 12 hours) upper GI endoscopy may be considered in patients with high risk clinical features, namely: hemodynamic instability (tachycardia, hypotension) that persists despite ongoing attempts at volume resuscitation; in-hospital bloody emesis/nasogastric aspirate; or contraindication to the interruption of anticoagulation (strong recommendation, moderate quality evidence). MR8. ESGE recommends that peptic ulcers with spurting or oozing bleeding (Forrest classification Ia and Ib, respectively) or with a nonbleeding visible vessel (Forrest classification IIa) receive endoscopic hemostasis because these lesions are at high risk for persistent bleeding or rebleeding (strong recommendation, high quality evidence). MR9. ESGE recommends that peptic ulcers with an adherent clot (Forrest classification IIb) be considered for endoscopic clot removal. Once the clot is removed, any identified underlying active bleeding (Forrest classification Ia or Ib) or nonbleeding visible vessel (Forrest classification IIa) should receive endoscopic hemostasis (weak recommendation, moderate quality evidence). MR10. In patients with peptic ulcers having a flat pigmented spot (Forrest classification IIc) or clean base (Forrest classification III), ESGE does not recommend endoscopic hemostasis as these stigmata present a low risk of recurrent bleeding. In selected clinical settings, these patients may be discharged to home on standard PPI therapy, e. g., oral PPI once-daily (strong recommendation, moderate quality evidence). MR11. ESGE recommends that epinephrine injection therapy not be used as endoscopic monotherapy. If used, it should be combined with a second endoscopic hemostasis modality (strong recommendation, high quality evidence). MR12. ESGE recommends PPI therapy for patients who receive endoscopic hemostasis and for patients with adherent clot not receiving endoscopic hemostasis. PPI therapy should be high dose and administered as an intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour) for 72 hours post endoscopy (strong recommendation, high quality evidence). MR13. ESGE does not recommend routine second-look endoscopy as part of the management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). However, in patients with clinical evidence of rebleeding following successful initial endoscopic hemostasis, ESGE recommends repeat upper endoscopy with hemostasis if indicated. In the case of failure of this second attempt at hemostasis, transcatheter angiographic embolization (TAE) or surgery should be considered (strong recommendation, high quality evidence). MR14. In patients with NVUGIH secondary to peptic ulcer, ESGE recommends investigating for the presence of Helicobacter pylori in the acute setting with initiation of appropriate antibiotic therapy when H. pylori is detected. Re-testing for H. pylori should be performed in those patients with a negative test in the acute setting. Documentation of successful H. pylori eradication is recommended (strong recommendation, high quality evidence). MR15. In patients receiving low dose aspirin for secondary cardiovascular prophylaxis who develop peptic ulcer bleeding, ESGE recommends aspirin be resumed immediately following index endoscopy if the risk of rebleeding is low (e. g., FIIc, FIII). In patients with high risk peptic ulcer (FIa, FIb, FIIa, FIIb), early reintroduction of aspirin by day 3 after index endoscopy is recommended, provided that adequate hemostasis has been established (strong recommendation, moderate quality evidence).

Hemodynamic status is first assessed, and resuscitation initiated as needed. Patients are risk-stratified based on features such as hemodynamic status, comorbidities, age, and laboratory tests. Pre-endoscopic erythromycin is considered to increase diagnostic yield at first endoscopy. Pre-endoscopic proton pump inhibitor (PPI) may be considered to decrease the need for endoscopic therapy but does not improve clinical outcomes. Upper endoscopy is generally performed within 24h. The endoscopic features of ulcers direct further management. Patients with active bleeding or non-bleeding visible vessels receive endoscopic therapy (e.g., bipolar electrocoagulation, heater probe, sclerosant, clips) and those with an adherent clot may receive endoscopic therapy; these patients then receive intravenous PPI with a bolus followed by continuous infusion. Patients with flat spots or clean-based ulcers do not require endoscopic therapy or intensive PPI therapy. Recurrent bleeding after endoscopic therapy is treated with a second endoscopic treatment; if bleeding persists or recurs, treatment with surgery or interventional radiology is undertaken. Prevention of recurrent bleeding is based on the etiology of the bleeding ulcer. H. pylori is eradicated and after cure is documented anti-ulcer therapy is generally not given. Nonsteroidal anti-inflammatory drugs (NSAIDs) are stopped; if they must be resumed low-dose COX-2-selective NSAID plus PPI is used. Patients with established cardiovascular disease who require aspirin should start PPI and generally re-institute aspirin soon after bleeding ceases (within 7 days and ideally 1-3 days).

Also to evaluate the clinical effectiveness of PPI therapy, compared with other treatments, for the prevention of subsequent bleeds in patients who had previously experienced peptic ulcer (PU) bleeding. Electronic databases and major conference proceedings were searched up to February 2006. Data were collected from the systematic reviews addressing each research objective. These were then entered into an economic model to compare the costs and quality-adjusted life-days of alternative management strategies over a 28-day period for patients who have had UGI bleeding. A Markov model with a Monte Carlo simulation used data from the systematic reviews to identify the most cost-effective treatment strategy for the prevention of UGI bleeding (first and subsequent) among NSAID users using an outcome of costs per quality-adjusted life-years (QALYs) over a lifetime from age 50 years. PPI treatment initiated after endoscopic diagnosis of PU bleeding significantly reduced re-bleeding and surgery compared with placebo or H2RA. Although there was no evidence of an overall effect of PPI treatment on all-cause mortality, PPIs significantly reduced mortality in subgroups when studies conducted in Asia were examined in isolation or when the analysis was confined to patients with high-risk endoscopic findings. PPI treatment initiated prior to endoscopy in UGI bleeding significantly reduced the proportion of patients with stigmata of recent haemorrhage (SRH) at index endoscopy compared with placebo or H2RA, but there was no evidence that PPI treatment affected clinically important outcomes. Giving oral PPI both before and after endoscopy, with endoscopic haemostatic therapy (EHT) for those with major SRH, is preferred to all others on cost-effectiveness grounds at any threshold over 25,000 pounds per QALY, even if only short-term effects are taken into account, and at any threshold over 200 pounds per life-year gained if long-term effects are included. The risk of NSAID-induced endoscopic gastric and duodenal ulcers was reduced by standard doses of PPI and misoprostol, and double doses of H2RAs. Standard doses of H2RAs reduced the risk of endoscopic duodenal ulcers. PPIs reduced NSAID-induced dyspepsia. PPIs were superior to misoprostol in preventing recurrence of NSAID-induced endoscopic duodenal ulcers, but PPIs were comparable to misoprostol in preventing the recurrence of NSAID-induced endoscopic gastric ulcers. Full-dose misoprostol reduced bleeding, perforation or gastric outlet obstruction due to NSAID-induced ulcers, but misoprostol was poorly tolerated and associated with frequent adverse effects. H. pylori eradication treatment was equally effective with PPI treatment for the primary or secondary prevention of endoscopic ulcers in NSAID users. H. pylori eradication treatment was more effective than placebo for the primary prevention of endoscopic PU and for the prevention of re-bleeding from PU in NSAID users. With regard to primary and secondary prevention of bleeding PU in NSAID users, the two most cost-effective strategies are H. pylori eradication alone, and H. pylori eradication followed by misoprostol (substituted by a PPI, if misoprostol is not tolerated) at an additional 4810 pounds per QALY. In patients who had previously experienced a bleed from a PU, re-bleeding was less frequent after H. pylori eradication therapy than after non-eradication antisecretory therapy, whether or not the latter was combined with long-term maintenance antisecretory therapy. PPI treatment compared with placebo or H2RA reduces mortality following PU bleeding among patients with high-risk endoscopic findings, and reduces re-bleeding rates and surgical intervention. PPI treatment initiated prior to endoscopy in UGI bleeding significantly reduces the proportion of patients with SRH at index endoscopy but does not reduce mortality, re-bleeding or the need for surgery. The strategy of giving oral PPI before and after endoscopy, with EHT for those with major SRH, is likely to be the most cost-effective. Treatment of H. pylori infection was found to be more effective than antisecretory therapy in preventing recurrent bleeding from PU. H. pylori eradication alone or eradication followed by misoprostol (with switch to PPI, if misoprostol is not tolerated) are the two most cost-effective strategies for preventing bleeding ulcers among H. pylori-infected NSAID users, although the data cannot exclude PPIs also being cost-effective. Further large randomised controlled trials are needed to address areas such as PPI administration prior to endoscopic diagnosis, different doses and administration of PPIs, as well as the primary and secondary prevention of UGI bleeding." } ] } } }

Often a disturbance in one triggers a partial compensation in the other. A secondary (compensatory) process can be readily identified because it opposes the observed deviation in blood pH. For example, inadequate ventilation, a respiratory problem, causes a buildup of CO2, hence respiratory acidosis; the kidneys then attempt to compensate for the low pH by raising blood bicarbonate. The kidneys only partially compensate, so the patient may still have a low blood pH, i.e. acidosis.

The pH of blood can be represented by the Henderson-Hasselbalch equation: pH = pK + log [HCO3-]/PCO2 Thus, pH is a function of the ratio between bicarbonate ion concentration [HCO3-] and carbon dioxide tension (PCO2). There are four simple acid base disorders: (1) Metabolic acidosis, (2) respiratory acidosis, (3) metabolic alkalosis, and (4) respiratory alkalosis. Metabolic acidosis is the most common disorder encountered in clinical practice. The respiratory contribution to a change in pH can be determined by measuring PCO2 and the metabolic component by measuring the base excess. Unless it is desirable to know the oxygenation status of a patient, venous blood samples will usually be sufficient. Metabolic acidosis can result from an increase of acid in the body or by excess loss of bicarbonate. Measurement of the \"anion-gap\" [(Na+ + K+) - (Cl- + HCO3-)], may help to diagnose the cause of the metabolic acidosis. Treatment of all acid-base disorders must be aimed at diagnosis and correction of the underlying disease process. Specific treatment may be required when changes in pH are severe (pH less than 7.2 or pH greater than 7.6). Treatment of severe metabolic acidosis requires the use of sodium bicarbonate, but blood pH and gases should be monitored closely to avoid an \"overshoot\" alkalosis. Changes in pH may be accompanied by alterations in plasma potassium concentrations, and it is recommended that plasma potassium be monitored closely during treatment of acid-base disturbances." }, { "id": "wiki20220301en040_1095", "title": "Metabolic acidosis", "score": 0.013123061795628168, "content": "Diagnostic approach and causes Metabolic Acidosis is defined as a reduced serum pH, and an abnormal serum bicarbonate concentration of <22 mEq/L, below the normal range of 22 to 29 mEq/L. However, if a patient has other coexisting acid-base disorders, the pH level may be low, normal or high in the setting of metabolic acidosis. In the absence of chronic respiratory alkalosis, metabolic acidosis can be clinically diagnosed by measuring serum bicarbonate levels in the blood, which is generally a standard component of blood panels. Imperatively, when weighing a metabolic acidosis diagnosis, the change in serum bicarbonate levels over time should be considered; if baseline bicarbonate results are unknown, a single set of values may be misinterpreted.

Causes Acute Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction related to asthma or chronic obstructive pulmonary disease (COPD) exacerbation." }, { "id": "Physiology_Levy_3708", "title": "Physiology_Levy", "score": 0.012533596621139816, "content": "Table 37.2 ).

Calculation of standard bicarbonate and base excess or deficit is not necessary. The normal concentration of free hydrogen ions (H+) is approximately 40 millimoles/liter, which is equivalent to a pH of 7.4. The normal load of fixed acids is 50 to 80 millimoles in 24 hours. A steady state is maintained by excretion of an equal amount of H+ by the kidneys, which at the same time regenerate bicarbonate to replenish buffer stores. Renal excretion of H+ is in the form of titratable acid and ammonium. Synthesis of ammonia can increase severalfold under the stimulus of acidosis. This is the chief mechanism of long-term compensation. Metabolic acidosis can be due to an excessive acid load (endogenous or exogenous), impaired renal excretion of H+, or bicarbonate loss. Determination of the \"anion gap\" (unmeasured anions) helps to establish the mechanism of acidosis. Acidosis with a normal anion gap is due to either bicarbonate loss or ingestion of certain chloride salts. A gap larger than normal indicates the presence in the body of acids other than acidfying chloride salts. Management of metabolic acidosis requires accurate diagnosis, clear understanding of the mechansim, and individualized treatment. Metabloic alkalosis is due to loss of H+ (usually from stomach or kidneys) or ingestion of alkali. Measurement of urinary chloride helps establish the mechanism of alkalosis. In saline-responsive alkalosis, the urinary chloride level is very low. This is usually due to gastric loss of H+, and the condition responds to administration of saline solution. When the urinary chloride level is only moderately low, the alkalosis is probably not due to gastric loss of H+. This form of alkalosis (saline-resistant) does not respond well to administration of saline solution and requires use of potassium in treatment. Apprpriate compensatory responses to acidosis or alkalosis are critical to survival. Compensation for metabloic acidosis consists of hyperventilation and enhanced renal excretion of H+, chiefly as ammonium. In metabolic alkalosis, compensation is mainly renal excretion of bicarbonate. Respiratory acidosis is due to alveolar hypoventilation. In chronic situations, a compensatory rise in serum bicarbonate concentration is expected. Management consists of treatment of the cause of hypoventilation. Respiratory alkalosis is due to hyperventilation.

Very severe metabolic disorders were found, including a marked metabolic acidosis composed of diabetic ketoacidosis (she had suffered from insulin treated type 2 diabetes mellitus) and lactic acidosis with a very high anion gap (42) and a hyperosmotic state (blood glucose 1202 mg/dl). There were pathognomonic electrocardiographic abnormalities, J-wave of Osborn and prolonged repolarization. Slow atrial fibrillation with a ventricular response of 30 bpm followed by a nodal rhythm of 12 bpm and reversible cardiac arrest were recorded. The pulse and blood pressure were unobtainable. Despite the successful resuscitation and hemodynamic and cognitive improvement, rhabdomyolysis (CKP 6580 u/L), renal failure and hepatic damage developed. She was extubated and treated with intravenous fluids containing dopamine, bicarbonate, insulin and antibiotics. Her medical condition gradually improved, and she was discharged clear minded, functioning very well and independent. Renal and liver tests returned eventually to normal limits. Progressive bradycardia, hypotension and death due to ventricular fibrillation or asystole commonly occur during severe hypothermia. Respiratory and metabolic, sometimes lactic, acidosis, lethargy and coma, hypercoagulopathy, hyperosmolar state, acute pancreatitis and renal and hepatic failure are frequent complications of hypothermia. Underlying predisposing causes of hypothermia are diabetic ketoacidosis, cerebrovascular disease, mental retardation, hypothyroidism, pituitary and adrenal insufficiency, malnutrition, acute alcoholism, liver damage, hypoglycemia, sepsis, hypothalamic dysfunction, sepsis and polypharmacy, and especially, the use of sedative and narcotic drugs.

The two-buffer model consisted of different aqueous solutions of bicarbonate/CO(2) (pCO(2), sCO(2), pK(1)), HEPES buffer (A(tot), pK(a)) and electrolytes. These were used to calculate the pH from the independent variables according to Stewart - strong ion difference (SID), pCO(2) and total concentration of the weak acids (A(tot)) - from which all other dependent variables (cHCO(3)(-), cA(-), BB, BE) were obtained and compared with the measured values. The normal pH (7.408) was calculated from the normal values for SID (48 mmol/l), pCO(2) (40 mmHg) and A(tot) (45.2 mmol/l) and agreed perfectly with the measured value (7.409+/-0.001). This was also valid for all calculated and measured pH values when the SID was varied: non-respiratory alkalosis ( upward arrow) or acidosis ( downward arrow), pCO(2):respiratory acidosis ( upward arrow) or alkalosis ( downward arrow) and A(tot):hyperproteinemic acidosis ( upward arrow) or hypoproteinemic alkalosis ( downward arrow) were varied and the sum of the buffer bases (BB) was always equal to the SID. All changes and hence BE were also equal, providing that A(tot) was normal. This was not the case, however, if A(tot) was outside the normal range, when BE was then the difference from the normal BB at the respective reference point.

The aim of our study was to analyse the epidemiological and clinical characteristics of erythema infectiosum in children. This study included 88 children observed in the Department of Dermatology of the Institute for Child and Youth Health Care of Vojvodina, in Novi Sad, during the period January 2000-December 2009.

During the study period, EI was detected in 88 children (44 females and 44 males), 0.213% of the total number of 41,345 children observed in the Department of Dermatology. An outbreak of erythema infectiosum was observed from December 2001 to September 2002, with the peak frequency in April and May 2002 and 39 diagnosed cases, and stable number of cases from 2005 to 2009 (a total of 49 diagnosed cases).

The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising &lt;1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with \"playing\" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are \"high-risk\" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a \"hair ball\" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), transmitted primarily through respiratory droplets and aerosols. Even though the COVID-19 vaccine has become available since December 2020, the main preventive measures still include social distancing, hand washing, and the use of protective face masks. By May 22, 2021, 3,437,545 deaths caused by SARS-CoV-2 have been registered by WHO, confirming the burden of this disease (1). Consequently, the pandemic has become a challenge for health care systems, as they had to be focused on the care of patients with COVID-19. During the first lockdown from March to May 2020, it was advised to postpone clinical visits whenever this could be done without risk. This recommendation was mainly aimed at older patients and those with chronic diseases, as it has been shown that they are at greater risk for complications from COVID-19. Renal transplant recipients (RTRs) are at a greater risk for infections and different cancers due to their permanent immunosuppressive therapy. The most common malignancies in RTRs are skin cancers, particularly non-melanoma skin cancers. It has been estimated that RTRs have a 65-250 times higher risk for cutaneous squamous cell carcinoma (SCC), 10 times higher risk for basal cell carcinoma, and 2-5 times higher risk for melanoma when compared with the general population (2-4). RTRs are at a higher risk for complications from COVID-19, not only because of their immunosuppressive therapy but also because of different comorbidities, such as hypertension, cardiovascular disease, and diabetes mellitus (5). Therefore, RTRs tend to limit their medical visits and postpone clinical examinations for skin cancer screenings. Moreover, during clinical visits the patients are commonly asked to keep their protective masks on, increasing the risk of overlooking their facial skin changes. Herein we present two RTRs who developed skin cancers during the COVID-19 pandemic, and the tumors were diagnosed with a significant delay. Patient 1 A 67-year-old woman with unknown primary kidney disease received a renal allograft from a deceased donor in 2014. The immunosuppressive protocol included antithymocyte globulin induction with tacrolimus, mycophenolate mofetil, and steroid maintenance. In January 2020, she had noticed a reddish squamous lesion on her right cheek, which enlarged slowly. Since there were no other symptoms, she postponed the dermatologic examination. Additionally, she further postponed the visit to her physician during the pandemic as she wanted to avoid social contact as much as possible. One year later, at the nephrologist's examination, she was asked to take off her face mask for a skin check, and two skin tumors on her right cheek were noticed (Figure 1). One lesion was located at the angle of her mandible and presented as a hypertrophic, sharply marginated lesion with central crusting and a diameter of 2 cm. The other lesion was at the right zygomatic region and appeared as a scaly, erythematous lesion with a diameter of 7 mm. The patient was referred to a dermatologist, and a biopsy of both lesions was indicated. The pathohistological analysis revealed cutaneous SCC in situ for the mandibular lesion and actinic keratosis for the zygomatic lesion. SCC in situ has been excised, and actinic keratosis was treated by cryosurgery. Patient 2 A 66-year-old woman received a renal allograft from a deceased donor in 2010 due to chronic glomerulonephritis without biopsy. The immunosuppressive protocol included basiliximab induction with tacrolimus, mycophenolate mofetil, and steroid maintenance. In June 2020, an erosion occurred at her left infraocular area and did not heal but instead gradually enlarged. The patient suspected that the \"wound\" developed due to the friction from the rim of her eyeglasses. Six months later, the nephrologist noticed the erosion which was 10×5 mm in size with a slightly elevated, pearl-colored margin (Figure 2). The patient was referred to a dermatologist who indicated tumor excision due to suspected basal cell carcinoma. The pathohistological analysis confirmed the clinical diagnosis. DISCUSSION Both presented patients did not inform their family physicians about their skin changes because they avoided all non-nephrological medical visits during the pandemic. The additional reason for the diagnostic delay was the fact that they kept the masks on their faces during most examinations, with the skin lesions behind the mask consequently remaining unnoticed. The problem of diagnostic delay of skin cancers during the COVID-19 pandemic has been recognized by several studies. Canadian authors compared the number of biopsies for skin cancers during the first 15 weeks in 2020 and during the same period in 2019. They found a decrease in the number of biopsies for non-melanoma skin cancers (NMSC) and melanoma of 18% and 27%, respectively (6). A multicenter study performed in northern-central Italy showed that the number of skin cancer (NMSC and melanoma) diagnoses fell by 56.7% in weeks 11 to 20 of 2020 compared with the average number noted in the same periods of 2018 and 2019 (7). Furthermore, a single-center retrospective study in Italy demonstrated that the number of advanced skin cancers surgically treated between May 18 and November 18, 2020, was significantly higher than in the same period in 2019. These findings led the authors to conclude that the surgical excisions were postponed due to the delay in follow-ups, which resulted in increased incidence of advanced skin cancers (8). RTRs are at particular risk of severe consequences from diagnostic delay with regard to skin cancers. Namely, skin cancers in RTRs are more aggressive and are associated with a higher incidence rate of metastases and recurrences than in the general population (9). Therefore, RTRs should be advised to regularly check their skin for potential skin cancer, which includes self-examinations and dermatologic follow-ups." }, { "id": "wiki20220301en009_127411", "title": "Rubella", "score": 0.009345794392523364, "content": "Signs and symptoms Rubella has symptoms similar to those of flu.

A previously healthy 42-year old japanese woman presented to the Travel Clinic of Seirei Yokohama Hospital with complaints of 4 days of fever, joint aches, bone pain, and a macropapular rash on her torso. She had returned from Bali 5 days previously. During her 1-week stay, one day was spent in rural, mountainous areas where she was exposed to several mosquito bites. The 1st serum sample collected 4 days after the disease onset gave positive result in the rapid dengue IgM antibody test and the rapid dengue NS1 antigen immunechromatographic test. The DENV-1 genome was detected with RT-PCR. Her 13-year old son, who had accompanied her, was also diagnosed as having dengue fever and he recovered without event. The Above-mentioned symptoms resolved within one week. However, the patient suffered from prolonged depression. She also noticed loss of hair 3 months after the disease onset Administration of a Serotonin-Noradrenalin Reuptake Inhibitor and a minor tranquillizer required to allow her requied to lead a normal life. Although she gradually felt better, it took approximately 2 years until she had recovered completely without taking any antidepressant and minor tranquillizer. It is a well-known fact in endemic countries that dengue fever could have an significant impact on the patients' mental well-being. However, it appears that physicians in non-endemic countries are not fully aware of the prolonged depression, which can occur subsequent to the acute illness. Follow-up consultations of returing travelers who have recoverd from dengu fever should be arranged to monitor their mental and emotional states closely." } ] } } }

The patients' age, gender, days of fever, respiratory symptoms (e.g. cough and sputum), peripheral blood count and etiology (pathogens) of CAP were recorded. Of all the 6539 fever outpatients, those aged 10-39 and above 60 years old accounted for 61.0% and 15.6%, respectively. In total, 402 were diagnosed with CAP with an incidence rate of 6.1%. Among them, 38.1% were above 60 years old. The prevalence increased with age. Of the 402 CAP patients, 36.8% (148/402) presented no respiratory symptoms and 30.1% (121/402) had positive etiology.

Epidemiologic studies describe a wide range of causative organisms, including Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, Legionella spp., Moraxella catarrhalis, Chlamydia pneumoniae and viruses such as influenza A and B. However, the frequency with which they are reported varies widely. On analysis of these studies, the variation can be explained by a number of factors. The results depend on the definition of pneumonia and the criteria for assigning a causative role to any particular organism. Older studies have not included diagnostic methods for newly described organisms such as C. pneumoniae and Legionella spp. The improved diagnostic methods for these organisms and for Mycoplasma pneumoniae are reflected in more recent studies. Further variation depends on the population studied. As many patients with mild pneumonia are successfully treated in the community, those studies that are hospital-based include patients with more severe pneumonia often in the elderly or in patients with underlying diseases such as chronic obstructive pulmonary disease. The prior use of antibiotics not only contributes to the high percentage of cases for which no etiologic agent is found, but also ensures that treatment failures are selected for hospitalization. This further changes the result, depending on the antibiotic agents used most commonly in the community. The inclusion of nursing home patients or groups where alcoholism is more common will also favor particular organisms. Finally, the timing of the study may be such that an epidemic is included. This has relevance mostly for Mycoplasma pneumoniae, C. pneumoniae, Legionella spp. and influenza. In the assessment of the patient with community-acquired pneumonia, any one of the above organisms can be considered to be responsible. As initial treatment is empirical, other information can be used to ensure that an antibiotic with an adequate spectrum is chosen. Factors of importance are age, underlying illness, severity of disease and any locally recognized epidemics or endemic organisms. Differences in clinical presentation are not sufficiently distinct to allow for accurate prediction of the causative agent. Similarly, chest radiograph changes are not sufficiently specific to discriminate reliably between diverse organisms such as S. pneumoniae, Mycoplasma pneumoniae and Legionella spp. Current recommendations for choice of an empirical antibiotic agent are therefore based, not on the assumption of a single etiologic agent indicated by clinical presentation or radiographic appearances, but on age of the patient, severity of illness, the presence of underlying conditions and the range of possible organisms in that patient group." }, { "id": "pubmed23n0496_7620", "title": "Guidelines for community-acquired pneumonia: are they reflected in practice?", "score": 0.01195135588481968, "content": "Community-acquired pneumonia (CAP) is common, costly, and clinically serious. Several national and international practice guidelines have been developed to promote more appropriate, cost-effective care for patients with CAP. This article compares and contrasts eight international practice guidelines for the management of CAP, describes the extent to which recommendations are reflected in practice, and proposes explanations for non-adherence to guidelines. We found consistency in recommendations across all the guidelines for the management of patients with CAP requiring intensive care. In this setting, all guidelines recommend chest radiography, sputum Gram stain and culture, blood cultures, testing for Legionella pneumophila, and timely administration of antibiotics active against both typical (i.e. Streptococcus pneumoniae, Hemophilus influenzae) and atypical organisms (i.e. Legionella spp., Mycoplasma pneumoniae, and Chlamydia pneumoniae). Recommendations for the management of the average inpatient with pneumonia were more variable, with the greatest differences between the North American and European guidelines. The North American guidelines (in contrast to European ones), recommended empiric treatment of typical and atypical organisms in all inpatients. There were also differences in policies regarding the necessity of chest radiography, sputum studies, and serologic testing. Some guidelines explicitly embrace the use of prediction rules to inform the decision to hospitalize, while others do not. Some of these admission decision algorithms focus on identifying low risk patients, while others are most concerned with high risk patients. There was also considerable variation in the specificity and operationalization of clinical criteria for switching from parenteral to oral antibiotics or judging appropriateness for discharge. Many recommendations for key management decisions tended to lack explicit, objective, and actionable criteria that could be easily implemented in real world practice. Review of the pneumonia literature revealed that physician performance of guideline-recommended best practices is often suboptimal. Administration of timely antibiotics (&lt; or =8 hours of presentation) and use of first-line antibiotics occurred in 75-85% and 18-79% of cases, respectively. Collection of blood cultures within 24 hours of presentation and prior to administration of antibiotics was achieved in 69-83% and 63-82% of cases, respectively. Screening the eligibility of CAP patients for hospital-based pneumococcal and influenza vaccination occurred on average in 11 and 14% of hospitalizations, respectively, in the US. Lack of awareness of guidelines, conflicting advice among them, and lack of specific, objective, actionable recommendations most likely contribute to nonadherence to CAP guidelines. Increased attention to these factors will be needed if professional society practice guidelines are to fulfill their promise as tools for improving the quality and outcomes of care for patients with pneumonia." }, { "id": "pubmed23n0373_1293", "title": "Study of community acquired pneumonia aetiology (SCAPA) in adults admitted to hospital: implications for management guidelines.", "score": 0.01113133151349712, "content": "Since the last British study of the microbial aetiology of community acquired pneumonia (CAP) about 20 years ago, new organisms have been identified (for example, Chlamydia pneumoniae), new antibiotics introduced, and fresh advances made in microbiological techniques.

Pathogens were identified in 324/610 patients (53.1%) with valid serum samples and sputum cultures as follows: Mycoplasma pneumoniae (126, 20.7%), Streptococcus pneumoniae (63, 10.3%), Haemophilus influenzae (56, 9.2%), Chlamydia pneumoniae (40, 6.6%), Klebsiella pneumoniae (37, 6.1%), Legionella pneumophila (31, 5.1%), Staphylococcus aureus (23, 3.8%), Escherichia coli (10, 1.6%), Moraxella catarrhalis (8, 1.3%), Pseudomonas aeruginosa (6, 1.0%). Of 195 patients with a bacterial pathogen, an atypical pathogen was identified in 62 (10.2%) cases. The non-susceptibility rate of Streptococcus pneumoniae to penicillin, azithromycin, and moxifloxacin was 20.3%, 75.4% and 4.3% respectively. Atypical pathogens have important role in CAP, with Mycoplasma pneumoniae being the most common pathogen, and mixed infection of atypical pathogens with bacteria was found in 10.2% of the cases. Streptococcus pneumoniae and Haemophilus influenzae remain the most important bacteria for CAP.

Univariate analysis showed that CAP by LP was more frequent in middle-aged, male healthy (but alcohol drinking) patients than CAP by other etiology. Moreover, the lack of response to previous beta-lactamic drugs, headache, diarrhea, severe hyponatremia, and elevation in serum creatine kinase (CK) levels on presentation were more frequent in CAP by LP, while cough, expectoration, and thoracic pain were more frequent in CAP by other bacterial etiology.

ACTH determinations should allow to classify the etiology as belonging to either the ACTH-dependent or the ACTH-independent group, but variable biological characteristics of pituitary or ectopic ACTH secreting tumors may complicate the investigation. For small pituitary adenomas, magnetic resonance imaging (MRI) has increased the sensitivity of detection over CT scans; however, the small average size of 4-5 mm of corticotroph adenomas, including a significant proportion of tumors of less than 3 mm, limits MRI to a sensitivity which varies between 42-80%. In situations where a pituitary tumor is small (&lt; 6 mm or not detectable by MRI), it is recommended to perform bilateral petrosal sinus sampling including a stimulation of ACTH secretion by CRH administration, to confirm the pituitary source of ACTH prior to undertaking pituitary exploration. Transsphenoidal selective removal of the pituitary corticotroph adenoma is the treatment of choice; immediate surgical success rate is high (75-90%) when the tumor is a microadenoma visible at MRI. However success rate decreases (50-60%) when surgical exploration is performed without radiological detection. The other end of the spectrum of size of the corticotroph adenomas includes either tumors larger than 10 mm (macroadenomas) or tumors invading the cavernous sinus; in either case, immediate success rate of surgical removal is only 50-70%. Radiotherapy coupled to medical (ketoconazole, op \"DDD) or surgical (bilateral laparoscopic adrenalectomy) control of hypercorticism may be necessary. Longer follow-up series indicate a relapse rate of up to 25% after 10 years, suggesting frequent incomplete resection. It is hoped that further progress in our understanding of the molecular basis of the pathophysiology of this disease will allow the development of new therapeutic strategies which will circumvent the current limitations resulting in part, from the size of these tumors." }, { "id": "pubmed23n0276_17309", "title": "[The treatment of Cushing's disease].", "score": 0.016876750700280115, "content": "The differential diagnosis of Cushing's disease remains difficult to establish.

The treatment consisting of surgery, radiotherapy and drug therapy or a combination of these modalities is aimed at the control of tumor cell proliferation and--in endocrine active tumors--the reduction of hormone secretion. However, the slow proliferation characteristics of pituitary tumors necessitate long-term studies for the evaluation of the treatment results. In the last decade there has been continuous improvement in surgical procedures, radiotherapy techniques and drug generation. In this paper, literature will be reviewed to assess the role of modern radiotherapy and radiosurgery in the management of pituitary adenomas. Nowadays, magnetic resonance imaging for the definition of the target volume and a real three-dimensional (3-D) treatment planning with field conformation and the possibility for non-coplanar irradiation has to be recommended. Most groups irradiate these benign tumors with single doses of 1.8-2.0 Gy up to a total dose of 45 Gy or 50.4 Gy in extensive parasellar adenomas. Adenomas are mostly small, well circumscribed lesions, and have, therefore, attracted the use of stereotactically guided high-precision irradiation techniques which allow extreme focussing and provide steep dose gradients with selective treatment of the target and optimal protection of the surrounding brain tissue. Radiation therapy controls tumor growth in 80-98% of patients with non-secreting adenomas and 67-89% for endocrine active tumors. Reviewing the recent literature including endocrine active and non-secreting adenomas, irradiated postoperatively or in case of recurrence the 5-, 10- and 15-year local control rates amount 92%, 89% and 79%. In cases of microprolactinoma primary therapy consists of dopamine agonists. Irradiation should be preferred in patients with macroprolactinomas, when drug therapy and/or surgery failed or for patients medically unsuitable for surgery. Reduction and control of prolactin secretion can be achieved in 44-70% of patients. After radiotherapy in acromegaly patients somatomedin-C and growth hormone concentrations decrease to normal levels in 70-90%, with a decrease rate of 10-30% per year. Hypercortisolism is controlled in 50-83% of adults and 80% of children with Cushing's disease, generally in less than 9 months. Hypopituitarism is the most common side effect of pituitary irradiation with an incidence of 13-56%. Long-term overall risk for brain necrosis in a total of 1,388 analyzed patients was estimated to be 0.2%. Other side effects are rare too, and do also depend on the damage produced by tumor itself or preceding surgery. They include deterioration of vision in 1.7% of all cases, vascular changes in 6.3%, neuropsychological disorders such as dementia in 0.7% and secondary malignancies in 0.8%, if single doses of 2.0 Gy and total doses of 50 Gy are not exceeded. Conventional radiation therapy of pituitary adenoma is highly effective. It is recommended after subtotal resection of primary tumors such as macroadenomas, after gross total resection from endocrine active adenomas with postsurgical hormone secretion and for recurrent tumors. Radiosurgery seems to be a possible treatment alternative in experienced centers, and only in patients with adenomas smaller than 25-30 mm with a minimum distance of 2-3 mm to the chiasm." }, { "id": "pubmed23n0328_12253", "title": "[Treatment of pituitary adenoma].", "score": 0.014052540081128067, "content": "RECOMMENDED TREATMENTS: The different therapeutic strategies proposed for pituitary adenomas are relatively well-known thanks to numerous studies evaluating their effect on outcome. Unfortunately, large comparative clinical trials are difficult to construct due to the small number of cases of this rare condition. Therapeutic recommendations are thus generally based on the opinion of recognized experts. MICROADENOMA: Small (&lt; 10 mm) prolactin-secreting adenomas should be treated surgically, generally by transsphenoidal adenomectomy, or medically by dopaminergic agonists: bromocriptin, quinagolide or cabergolin (the two latter drugs are more effective and better tolerated than their parent compound bromocriptin). MACROADENOMA: The expected success rate for surgical treatment of macroadenomas is low and dopaminergic agonists is generally recommended (including cases with visual impairment since the effect can be very rapid). Prolactin levels can be lowered and tumor volume reduced (in &gt; 70% of cases). ACROMEGALY: Surgery is the firs intention treatment for acromegaly. In case of unsuccessful surgery (the criteria for \"cure\" are much more strict in 1998 than previously), somatostatin analog and/or hypothalamo-hypophyseal radiotherapy are recommended. Slow release formulations of somatostatin analogs can now be given by monthly (octreotide LP) or biweekly (lanreotide LP) injections. CUSHING'S DISEASE: Cure can be achieved in &gt; 80% of cases with surgery, the first intention treatment of choice. If surgery is unsuccessful, radiotherapy can be proposed associated with anticortisol drugs (mitotane), if needed, while waiting for the late effect of radiotherapy.

All patients with pituitary tumors should be evaluated for gonadal, thyroid and adrenal function as well as PRL and GH secretion. Specific stimulation and suppression tests for pituitary hormones are performed in selected situations for detecting the type of hypersecretion or the response to treatment. Imaging procedures (mainly magnetic resonance imaging, MRI, nowadays) determine the presence, size and extent of the lesion. The classification of pituitary tumors is based on the staining properties of the cell cytoplasm viewed by light microscopy and immunocytochemistry revealing the secretory pattern of the adenoma. Treatment of pituitary adenomas consists of surgery (performed in more than 99% of cases via a transphenoidal route) and radiotherapy, generally fractionated or, in selected cases, using stereotactic techniques such as gamma-knife. The availability of medical treatment (dopamine, DA, agonists, somatostatin analogs, GH-receptor antagonists...) has profoundly modified the indications of radiotherapy, drugs being now generally used as a second-line treatment, after surgery (or even as first-line treatment). Based on the results of the different treatment modalities for each type of pituitary adenoma, recommendations will be proposed. They may be summarized as follows. For treatment of GH-secreting adenomas, trans-sphenoidal surgery is the first-line therapy except when the macroadenoma is giant or if surgery is contra-indicated; postoperative radiation therapy (fractionated, or by gamma-knife) is performed for partially resected tumors or when GH levels remain elevated (eventually after a trial of somatostatin analog). Somatostatin analogs, now available in slow release form, are proposed when surgery is contra-indicated, or has failed to normalize GH levels, or in waiting for the delayed effects of radiation therapy. If the probability of surgical cure is low (e.g. in patients with very large and/or invasive tumors), then somatostatin analogs may be reasonable primary therapeutic modality provided that the tumor does not threaten vision or neurological function. Pegvisomant, the new GH-receptor antagonist, is indicated in case of resistance to somatostatin analogs. Patients with PRL-secreting microadenomas may be treated either with trans-sphenoidal surgery or medically with DA agonists. In patients with macroadenomas, even in the presence of chiasmatic syndrome, DA agonists are now proposed as primary treatment. Indeed, effects on visual disturbances are often very rapid (within a few hours or days) and tumoral shrinkage is usually very significant. For patients with ACTH-secreting adenomas, primary therapy is generally trans-sphenoidal surgery by a skilled surgeon, whether or not a microadenoma is visible on MRI. Radiotherapy is reserved for patients who are subtotally resected or remain hyper-secretory after surgery. In waiting for the effects of radiotherapy, adrenal steroidogenesis inhibitors (mitotane, ketoconazole) may be indicated. If drugs are not available or not tolerated, bilateral adrenalectomy may be proposed. For patients with clinically non functioning adenomas (generally gonadotropin-secreting adenomas on immunocytochemistry), trans-sphenoidal surgery with or without postoperative radiation therapy is performed for almost all patients whether or not they have visual consequences of their tumor. Selected patients with small, incidentally discovered microadenomas may be carefully followed without immediate therapy." }, { "id": "pubmed23n0492_20465", "title": "Transsphenoidal surgery in Cushing disease: 10 years of experience in 34 consecutive cases.", "score": 0.013704318936877076, "content": "Cushing disease is a rare disorder.

Thirty-four patients, 26 of them female and eight of them male (mean age 40 years, range 13-74 years) were studied. All had obvious clinical signs and symptoms of Cushing syndrome. Magnetic resonance (MR) imaging was performed in all patients, and inferior petrosal sinus (IPS) sampling was done in 14. In 12 patients MR imaging indicated a pituitary tumor; 10 were microadenomas and two were macroadenomas. In six patients with no visible tumor, the results of IPS sampling supported the diagnosis. All patients underwent TSS; the mean follow-up duration was 6 +/- 0.5 years. Selective adenomectomy was performed in 32 and hemihypophysectomy in the other two patients. A cure was obtained in 31 patients (91%) after one TSS and in two more patients after further TSS; one patient was not cured despite two TSSs and one underwent bilateral adrenalectomy. Disease recurrence was seen in two patients after 3 years, and they were successfully treated with stereotactic gamma knife surgery. Half of the patients had an ACTH deficiency postoperatively, whereas one third had other pituitary hormone insufficiencies. There were no serious complications attributable to the surgical intervention. Transsphenoidal surgery with selective adenomectomy is an effective and safe treatment for Cushing disease.

Pituitary tumours can cause symptoms of mass effect and hormonal hypersecretion that can be reversed with surgical resection or debulking of the adenoma, radiotherapy, or medical treatment. Transsphenoidal adenomectomy is the treatment of choice for acromegaly, Cushing's disease, gonadotropin-secreting tumours; and thyrotropin (TSH)-secreting adenomas. Pituitary irradiation and medical therapy are secondary options. Conversely, medical treatment is the primary choice for prolactinomas. Dopamine agonists are very effective in the treatment of prolactin (PRL)-secreting tumours, with rates of control as high as 80 to 90% for microprolactinomas (&lt; 10 mm) and 60 to 75% for macroprolactinomas (&gt; or = 10 mm). Somatostatin analogues have also shown efficacy in patients with acromegaly who have not responded to surgery or in patients with TSH-secreting adenomas who have not improved with surgery and radiotherapy. In patients with Cushing's disease, who are not cured surgically or who relapse after pituitary adenomectomy and irradiation, steroidogenic inhibitors can be an efficient method of controlling the hypercortisolism. Pituitary insufficiency is the partial or complete loss of the anterior hypophyseal function, which is due to hypothalamic or pituitary disease. Although the classic sequence of loss of pituitary secretion is growth hormone (GH), gonadotropins, TSH, and corticotropin (ACTH), the order to begin the replacement therapy of the deficient hormone(s) is cortisol, thyroxine, androgens/estrogens and, if necessary, GH. There are multiple preparations that can be used to achieve clinical and biochemical improvement.

We can offer results of medium long follow-up for tumor growth and hormonal hypersecretion of pituitary adenomas in a relatively large series of patients. We have analyzed a group of 163 patients with pituitary adenoma treated with gamma knife during 5 years and followed 12-60 months, median 24 months after irradiation. An antiproliferative effect has been achieved in 1-2 years using the minimal dose to the margin 16-35 Gy, median 20 Gy in all our patients who were controlled by MRI (n = 126 patients).

Of these patients, 86 had received postoperative radiotherapy, and 5 had received radiotherapy alone. The median total dose was 51 Gy. Clinical symptoms related to mass effects or endocrine hypersecretion were assessed. The efficacy of radiotherapy was evaluated before treatment and during the follow-up period (1-14 years; median, 3 years) by estimating tumor size on computed tomography or magnetic resonance imaging in 56 patients, as well as by endocrine testing in the 22 patients who had secreting adenomas. Local control rate, prognostic factors, and side effects were analyzed. Mass-effect symptoms improved in 72% and 79% of patients who had such symptoms due to nonsecreting adenomas and secreting adenomas, respectively. Symptoms of endocrine hypersecretion abated in 67% of patients who had such symptoms. Excessive hormone levels normalized in 74% of patients who showed endocrine hypersecretions. The greatest size reduction was seen 3 years after the completion of radiotherapy (24% CR, 62% PR, 12% NC, and 3% PD in nonsecreting adenomas, and 32% CR, 36% PR, 27% NC, and 5% PD in secreting adenomas).

Retreatment with the gamma knife was done in 8 cases because of large tumors or uncontrolled hormones. Micro- and small adenomas could be cured by gamma knife radiosurgery alone. Surgical or chemical debulking was necessary before radiosurgery for a large tumor with extrasellar extension. Retreatment was effective and safe in some cases. Nonfunctioning adenomas showed higher control rates than functioning adenomas even with lower dose treatment. Cushing disease showed the best response because of the smallest tumor size with the highest dose treatment. Acromegaly and prolactinoma were difficult to control because of larger tumors with lower dose treatment. The rate of hormone normalization was also high in Cushing disease but lower in prolactinoma and lowest in acromegaly. High-dose treatment was necessary for functioning adenomas to control tumor growth and oversecretion of hormones.

Surgery of pituitary adenomas did not produce quite satisfactory results. Therefore radiosurgery using Leksell's gamma knife has become the most widely used method which-with the contribution of MRI-meets the most important demands of aimed irradiation: a sufficiently high dose of radiation of the tumour and minimal radiation load of functionally important surrounding structures. The objective of the investigation was to assemble experience with this therapeutic method. METHODS AND RESULTS. During the period between October 1992 and September 1994 a total of 41 patients were treated: 16 men, 12-66 years old, mean age 40.8 years; 25 women age 16-76 years, mean age 50.2 years. Female:male ratio 1.5 : 1. In 30 patients (73.2%) a microsurgical operation had preceded, in 5 (12.2%) conventional fractionated radiotherapy and in 11 patients (26.9%) primary radiosurgery. As far as the type of pituitary adenoma is concerned, it conditioned acromegaly in 30, Cushing's syndrome in 3 or Nelson's syndrome in 1, or a prolactinoma was involved (in 2 patients). In five instances the adenoma was hormonally inactive. Its localization was most frequently intrasellar (36), less frequently parasellar (5). The range of administered doses varied as regards the maximum between 12.5 and 80 Gy, the average being 46.8 Gy, to the periphery of the adenoma a dose of 10-49 Gy was administered, on average 24.7 Gy using a 50-80% isodose. The time interval after treatment is relatively short for detailed analysis or evaluation. During current evaluation the authors did not observe in any of the patients progression of the disease, and in several patients diminution of the tumour was found. Karnofski's score seemed to improve. CONCLUSIONS. Radiosurgery, using Leksell's gamma knife, is after failure of conservative and microsurgical therapeutic possibilities suitable further treatment of pituitary adenoma. In indicated cases it may be the first choice.

Of the 326 patients, 268 patients were followed by repeat Pap smears, colposcopy, cone biopsy, or endometrial curettage. The incidence of AGUS on Pap smears is approximately 0.08%. The mean age of the patients was 43 years (range 22-79 years). The most common complaint was abnormal vaginal bleeding. The gross findings of the cervix were normal to mild erosion. The following past histories of patients could affect the AGUS results on Pap smear: 30 had cone biopsy, 21 had Pap smears on pregnancy and within 8 weeks after delivery or evacuation, 3 were on hormonal replacement therapy, 2 had intrauterine devices for contraception, and 5 were undergoing follow-up after treatment of cervical cancer. The benign lesions detected during follow-up periods were 6 microglandular hyperplasia of the cervix, 5 atypical squamous metaplasia of the cervix, 2 cervical endometriosis, 2 tubal metaplasia, 10 cervical myoma, 11 cervical polyps, 9 endometrial polyps, 3 uterine myoma, 1 pelvic endometriosis, 1 ovarian endometriosis, and 4 uterine adenomyosis. The premalignant or malignant lesions of the cervix were 4 low-grade squamous intraepithelial lesions, 24 high-grade squamous intraepithelial lesions, 8 glandular atypia/dysplasia, 5 adenocarcinoma in situ, 3 microinvasive adenocarcinoma, and 4 invasive adenocarcinoma. The neoplastic lesions of the uterus were 6 endometrial hyperplasia, 11 endometrial adenocarcinoma, 1 malignant mixed Müllerian tumor, and 1 metastatic endometrial adenocarcinoma.

It is considered as a precancerous lesion uterine cervix carcinoma while they spontaneously regress in more than 60% of cases in two years. The problems related to the management of CIN1 as defined by the recommendations established in 2002 are the over-treatment and the great variability of clinical practices. Moreover, the potential of new tests has been investigated since 2002. To establish these new recommendations, the medline database has been consulted and the references essentially published between 2001 and May 2007 have been investigated. Publications were selected and classified according to their level of evidence (LE) in order to establish the grade of recommendations. One of the problems encountered when facing a CIN1 is to misdiagnose a more severe lesion firstly because of the intra- and interobserver variability and secondly because the colposcopy-directed biopsy is not mandatorily representative of the more severe lesion. Nevertheless, because the risk of cancer is extremely low, a conization is not necessary in an asymptomatic woman with a LSIL/ASC-US pap smear in case of CIN1 even if the squamocolumnar junction is not entirely visualized (LE 2/3). The endocervical curettage cannot be recommended in this case because its efficacy is globally poor and unknown in case of CIN1. Concerning the natural history of CIN1, the recent studies, which included more than 1200 women and more than 700 for two of them, confirm that the rate of progression of a CIN1 to a CIN3 or more severe lesion is less than 9% in the two years following the initial diagnosis (LE2). A CIN1 is associated with a risk of evolution to a CIN2 or more severe lesion that is not markedly more important than the risk associated with a LSIL/ASC-US pap smear while the colposcopy is normal or the biopsy is negative (between 8 and 13% whatever the results of the initial colposcopy) (LE 2/3). The recommendation in case of CIN1 is a strict follow-up. A colposcopy and a treatment are necessary in case of persistence or progression of the abnormalities (LE2). Data from trials studying the contribution of HPV testing in case of CIN1 show that its sensitivity is similar to repeat cytology with less referral to colposcopy to detect CIN2 or more severe lesion. These data have been considered to establish follow-up recommendations to manage CIN1: if the exams (cytology and/or HPV testing) at 12 months are negative, patients can be followed by an annual cytology. In case of aggravation of the cytology, a colposcopy is necessary. In case of positive HPV testing or persisting ASC-US/LSIL at 12 months, a repeat control is necessary at 18 months and a treatment is proposed according to colposcopy findings." }, { "id": "pubmed23n0039_4419", "title": "[Review of cervical smears in a gynaecologic department after a period of ten years under the consideration of colposcopic findings(author's transl)].", "score": 0.00980392156862745, "content": "The study comprises 96042 cytologic cases within a period of 10 years.

The first biopsy was nearly always taken by selective scraping of the ecto- and endocervix. Technical improvements of this method are explained. The efficiency of cytodiagnosis is especially pointed out by separating cases which could have been recognized or suspected by means of inspection or colposcopy only. 140 out of 282 carcinomata-in-situ and 7 invasive, mainly endocervical cancers (Ib-III), could only be diagnosed by a smear. In 17 woemn who turned out to have invasive cancer (Ib -III) a positive smear was the only reason for admission. Careful inspection of the cervix in the hospital, however, was sufficent to reveal the correct diagnosis. In our material the cervical smear could be of little help in cancer diagnosis of the upper genital tract such as adenocarcinoma of the corpus uteri, sarcoma and ovarian cancer. 39 of the 45 women with endometrial cancer cells in the specimen had bleeding anomalies, especially postmenopausal.

Cervical intraepithelial neoplasia 2 or worse yield by ECC alone was evaluated in analyses stratified by cervical cytology (atypical squamous cells of undetermined significance [ASC-US] or low-grade squamous intraepithelial lesions [LSIL] compared with atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions [ASC-H] or high-grade squamous intraepithelial lesions [HSIL] or worse), colposcopic impression (less than high-grade compared with high-grade), human papillomavirus (HPV)-16 infection status, whether the examination was satisfactory, and by ECC indications per the current guidelines for cervical cancer screening. The diagnostic value of ECC for detecting additional disease was evaluated by the number of lesion-directed ectocervical biopsies. Of the 204 women aged 30 years or older, 181 (88.7%) underwent ECC. Overall ECC detected 14.4% CIN 2 or worse (95% CI 10.0-20.2%).

A MEDLINE search was conducted using the search terms cervical intraepithelial neoplasia, low-grade dysplasia, mild dysplasia, low-risk squamous intraepithelial lesion, mild dyskaryosis, HPV, colposcopy, histology, and cytology. RESULTS.: Using a loop electrosurgical excision procedure or cone biopsy assessment of the cervix as the gold standard, a cytologic assessment of CIN 1 alone results in a high false-positive rate (51.5%) and a false-negative rate (24%) for CIN 3. The appropriate second test after low-grade squamous intraepithelial lesion (CIN 1) cytologic results includes repeat cervical cytologic analysis. Subsequent human papillomavirus testing provides no advantage and increases the cost of care. Immediate referral to colposcopy is costly but minimizes the percent of women lost to follow-up. Using a loop electrosurgical excision procedure or cone biopsy assessment of the cervix as the gold standard, the colposcopically directed biopsy may give a false-positive result (11.7%) or false-negative result (up to 31%) for CIN 3. One contributing issue is the moderate interobserver reliability of histologic analysis (kappa= 0.46). There are advantages and disadvantages to both the immediate and expectant management strategies. The most crucial concern for immediate treatment is overtreatment, and that for expectant management the high rate of patients lost to follow-up. Novel technologies, including MIB-1, p16(INK)4a, and genetic assessments, may be helpful in predicting those CIN 1 lesions destined to progress or to persist. The cytologic and histologic diagnosis of CIN 1 is fraught with problems related to the subjectivity of the diagnosis. Both management options are also fraught with concerns.

Recent progress has been made with the development of cold light, appropriate atraumatic instrumentation, video-camera and CO2 laser. Laparoscopy provides access to the pelvis, allowing for diagnosis and treatment of a variety of pathologies. The most frequent indication is the treatment of ectopic pregnancy. Salpingotomy with tubal preservation, the procedure of choice for young women wanting to become pregnant, has been used in 88 cases. However, tubal preservation is not always possible (rupture of the ovarian tube, hemosalpinx), and sometimes not even advisable (inflammatory lesions, homolateral recurrence) and salpingectomy was necessary in 294 cases. Another indication for salpingectomy is painful chronic salpingitis, resulting from an undetected or ill-treated Chlamydia trachomatis infection: 84 cases. Infertility surgery is the second most important indication for laparoscopic procedure. The authors have performed salpingoovariolysis in 49 cases, neosalpingostomy in 34 cases and fimbrioplasty in 31 cases.

The HPV triage arm was closed early because more than 80% of women were HPV positive, precluding efficient triage. The immediate colposcopy strategy yielded 55.9% sensitivity for cumulative cases of CIN grade 3 diagnosed over 2 years. A conservative management strategy of repeat cytology at the HSIL threshold referred 18.8% of women while detecting 48.4% of cumulative CIN grade 3. At lower cytology thresholds, sensitivity would improve but would ultimately yield unacceptably high referral rates. LSIL cytology is best managed by colposcopy initially, because there was no useful triage strategy identified.

In order to compare cone biopsy and hysterectomy in terms of their pick-up rates of cervical intraepithelial neoplasia and invasive cancer in women with abnormal pap smears, a retrospective review of entries in the histology reports of all cases of cone biopsy and hysterectomy done for abnormal Pap smears from 1975-2004 at the histopathology department of the University of Nigeria Teaching Hospital, Enugu, Nigeria, was carried out. The study revealed that 203 women with moderately to severely abnormal Pap smears were treated with either cone biopsy or hysterectomy. A total of 88 (43.3%) women had cone biopsy, while the remaining 115 (56.7%) had total abdominal hysterectomy. Those who had cone biopsy were significantly younger than those who had hysterectomy (mean ages: 44.6+/-8.8 vs 52.3+/-9.8 years; p=0.008). There was no significant difference in parity between those who had cone biopsy and those who had hysterectomy (mean parity: 5.7+/-2.3 vs 6.5+/-2.2; p=0.102).

Cone biopsy and hysterectomy did not differ significantly in their pick-up rates of the various categories of cervical lesions including invasive carcinoma (p&gt;0.05 for all categories). It was concluded that cone biopsy and hysterectomy have similar pick up rates for the various types of cervical lesions. For this reason, in the absence of colposcopy as occurs in many parts of the developing world, cone biopsy may be adequate treatment and should be offered first to women with moderately to severely abnormal Pap smears." }, { "id": "pubmed23n0298_12148", "title": "Adenoid basal carcinoma of the cervix: a potential pitfall in cervicovaginal cytology.", "score": 0.009259259259259259, "content": "Adenoid basal carcinoma (ABC) of the cervix is a quite uncommon, indolent, yet invasive neoplasm rarely identified on cervicovaginal smears.

Most patients with high-grade squamous intraepithelial lesion (HSIL)-cervical intraepithelial neoplasia 3 (CIN 3) Pap smear results require an excisional procedure for diagnostic or therapeutic reasons. \"See and treat\" is a surgical procedure that involves a loop electrosurgical excisional procedure (LEEP) simultaneously to diagnose and to treat premalignant cervical disease in one visit. This procedure eliminates a second visit that typically is required for treatment. Data is lacking on the incidence of CIN 2 and CIN 3 in patients with an HSIL (CIN 2) Pap smear result.

In an attempt to increase the chance of detecting the presence of CFTR gene abnormalities, 37 patients with CBAVD and one patient with congenital unilateral agenesis of the vas deferens (CUAVD) underwent an enlarged diagnostic protocol, which included screening for the most expected mutations of the CFTR gene in our population, evaluation of the five thymidine (5T) allelic variant, sweat test, respiratory function tests, evaluation of steatocrit, and an accurate evaluation of the history of the patient to search for symptoms commonly found in patients with CF. A single CFTR gene mutation was found in 18 patients (48.6%) with CBAVD and in the patient with CUAVD. The most frequent mutation observed was the Delta F508. Eleven patients (45.8%) had the 5T variant and in five of them it was not associated with any detectable mutation of the CFTR gene.

As many as 71% of CBVAD patients had the simultaneous presence of at least two signs and/or symptoms suggestive of CF, albeit they were of mild intensity and the patients felt fit and healthy. In conclusion, these results suggested that some patients with CBAVD without CFTR gene mutation or 5T variant, even when their sweat test is negative, may show clinical suspicion of carrying a CFTR gene mutation and therefore are at risk of generating children affected by CF if the partner carries a mutation as well. The screening for mutations and a careful clinical examination may contribute to better identification of patients with CFTR-related CBAVD." }, { "id": "article-17325_64", "title": "Albinism -- Treatment / Management -- Management of the Inheritable Nature of the Condition", "score": 0.009594882729211086, "content": "Genetics consultation before childbearing years is beneficial to parents of albino children considering future offspring, the patient with albinism and their siblings.

Thus, in a cohort of 257 persons that were referred to our laboratory for analysis of CF gene mutations, reverse line probe assays for the most common CF mutations were performed. These techniques were evaluated as routine first-line analyses of the CFTR gene status. METHODS: DNA from whole blood specimens was extracted and subjected to PCR amplification of 9 exons and 6 introns of the CFTR gene. The resulting amplicons were hybridised to probes for CF mutations and polymorphisms, immobilised on membranes supplied by Roche Molecular Systems, Inc. and Innogenetics, Inc. Denaturing gradient gel electrophoresis and sequencing of suspicious fragments indicating mutations were done with CF exon and intron specific primers. RESULTS: Of the 257 persons tested over the last three years (referrals based on 1) clinical symptoms typical for/indicative of CF, 2) indication for in vitro fertilisation, and 3) gene status determination because of anticipated parenthood and partners or relatives affected by CF), the reverse line blots detected heterozygote or homozygote mutations in the CFTR gene in 68 persons (26%). Eighty-three percent of those affected were heterozygous (47 persons) or homozygous (10 persons) for the DeltaF508 allele. The only other CF-alleles that we found with these tests were the G542X allele (3 persons), the G551D allele (3 persons), the 3849+10kb C-T allele (2 persons) the R117H allele (2 persons) and the 621+1G-T allele (1 person).Of the fifteen IVS8-5T-polymorphisms detected in intron 8, seven (47%) were found in males referred to us from IVF clinics. These seven 5T-alleles were all coupled with a heterozygous DeltaF508 allele, they make up 35% of the males with fertility problems (20 men) referred to us. CONCLUSIONS: In summary, the frequency of CF chromosomes in the cohort examined with these tests was 26%, with the DeltaF508 allele affecting 83% of the CF chromosomes. It is a substantial improvement for routine CF diagnostics to have available a test system for 30 mutations plus the polypyrimidine length variants in intron 8.

We are presented with a 68-year-old female patient. At that age the crystalline lens, although it does not normally have a cataract that needs surgery, it usually has increased in thickness. This implies that it projects the iris forward and reduces the depth of the anterior chamber. In an eye with a normal anterior chamber depth this is usually not a problem. But farsighted people already have a narrow anterior chamber. This is the usual combination we find in primary angular closure: farsightedness and age over 50-60 years. Younger hyperopes usually do not have this problem yet. And neither do older people who are emmetropic, myopic or have had cataract surgery. With this narrow angle, what triggers angular closure is mydriasis. That is, when you are in the penumbra, the pupil dilates and the iris thickens in the peripheral part, where it is already very close to the corneal endothelium in the case of a narrow chamber. Mydriasis then triggers angular closure, which is accompanied by ocular pain that may radiate backwards (headache). And increased intraocular pressure produces corneal edema that causes blurred vision. Therefore, option 1 is correct. Migraine does not have to be related to penumbra, and ocular pain and blurred vision is not particularly typical.

Her ocular history was significant only for moderate myopia and an idiopathic Horner syndrome in the left eye diagnosed at age 13. The patient endorsed a history of fluctuating and decreasing vision in the right eye over the past 6 months. She denied any ocular pain, previous ocular surgery, or recent trauma. The patient was otherwise healthy and denied any previous autoimmune disease or systemic infection. She wore soft, daily disposable contact lenses and reported no abnormalities on previous routine eye examinations. At presentation, the patient's uncorrected distance visual acuity was 20/25 in the right eye and 20/200 in the left. Lensometry revealed a previous refraction of -3.00 + 0.50× 150 in the right eye and -4.00 + 1.75× 174 in the left. Intraocular pressures (IOPs) were 4 mm Hg and 15 mm Hg by applanation, and central corneal thicknesses were 573 μm and 564 μm in the right and left eyes, respectively. Slitlamp examination revealed an area of scleral thinning near the limbus in the right eye from 5 to 7 o'clock with mild overlying chemosis (Figure 1JOURNAL/jcrs/04.03/02158034-202107000-00023/figure1/v/2021-06-26T110826Z/r/image-tiff). Gonioscopy showed an open angle with mild trabecular meshwork pigmentation in both eyes without any cyclodialysis clefts, peripheral anterior synechiae (PAS), or other abnormalities. Dilated fundus examination was significant for mild optic nerve edema and chorioretinal folds in the right eye. Optical coherence tomography (OCT) of the optic nerve confirmed mild disc edema (Figure 2JOURNAL/jcrs/04.03/02158034-202107000-00023/figure2/v/2021-06-26T110826Z/r/image-tiff) and OCT of the macula confirmed mild chorioretinal folds. Anterior segment OCT (AS-OCT) and ultrasound biomicroscopy failed to show any other abnormalities.

In one respect, the newly elevated IOP was considered transiently therapeutic to help reverse the hyperopic shift, disc edema, and hypotony-related maculopathy. However, the situation quickly became more worrisome when shortly thereafter the IOP elevated to 55 mm Hg at subsequent follow-up, and multiple IOP-lowering medications were initiated. Over numerous additional visits, the patient's IOPs ranged from 30 to 39 mm Hg in the right eye despite rapidly advancing to maximally tolerated medical therapy including acetazolamide. She was noted to have a new relative afferent pupillary defect of the right eye, and Humphrey visual fields showed early arcuate defects (Figure 4JOURNAL/jcrs/04.03/02158034-202107000-00023/figure4/v/2021-06-26T110826Z/r/image-tiff).

Recently it has gained more popularity, being used in many clinical conditions. Nowadays, the cases of glaucoma induced by topiramate have increased due to the use of this drug to induce weight loss. We here described a 29-year-old female presented with a one-day history of blurred vision in both eyes and headache. She was using a weight loss formula containing topiramate 100 milligrams. Ophthalmologic exam revealed an important myopic shift of -7.00 spherical diopters at presentation with intraocular pressure (IOP) of 32 mmHg and a shallow anterior chamber in both eyes. After discontinuous of topiramate and use of cycloplegic eyedrops, myopic shift improved and IOP controlled after two days. The anterior chamber was significantly deeper in both eyes after two weeks. It is theorized that topiramate can provoke a ciliochoroidal effusion and, therefore, can cause an anterior displacement of lens-iris diaphragm with a secondary angular closure. The treatment must include cycloplegic and discontinuation of the drug.

The thickness of the apical wall was 18 mm; the anterior wall, 12 mm; the posterior wall, 16 mm; and the interventricular septum, 17 mm on the left ventriculogram and biventriculogram. The coronary angiogram was normal. From these data, this patient was diagnosed as having HCM. However, follow-up studies disclosed resolution of the GNT with decreased high voltage (SV1 + RV5 = 26 mm). The catheterization performed in 1985 showed a decrease of wall thickness: the apical wall to 10 mm; the anterior wall, 9 mm; the posterior wall, 14 mm; and the interventricular septum, 14 mm. Ejection fraction was markedly decreased from 79.8% to 27.1%, and the wall motion was generally reduced. The coronary angiogram was normal. These findings resemble the clinical pictures of dilated cardiomyopathy (DCM). Case 2: A 58-year-old man was admitted in 1974 because of easy fatiguability. His ECG revealed a GNT in V4 (-10 mm) and high voltage (SV1 + RV5 = 75 mm). The patient was diagnosed as having HCM by cardiac catheterization, right ventricular biopsy and other procedures. In 1985, the depth of the GNT and the voltage of SV1 + RV5 regressed significantly (SV1 + RV5 = 26 mm).

Besides, there were so many various controversies in ECS. This article describes a case of ECS that was effectively treated with radical esophagectomy and adjuvant chemotherapy. Also, we discuss the presentation, differential diagnosis, treatment, and prognosis of ECS. A 58-year-old man presented with a history of progressive dysphagia and precordial pain after swallowing for 1 month. Esophagogastroduodenoscopy (EGD) revealed a large polypoid neoplasm that occupied the esophageal lumen 30 to 34 cm from the incisors. On the characteristic morphology, clinical symptom and biopsy findings, the ECS was the primary considerated. Computed tomography (CT) examination demonstrated no radiological evidence of metastatic disease. The patient underwent an Ivor Lewis esophagectomy, coupled with adequate lymph node dissection (2-field lymphadenectomy). ECS was confirmed by pathology report of postoperative. Then, the patient underwent adjuvant chemotherapy with docetaxel, oxaliplatin, and capecitabine. The patient remained alive without tumor recurrence at 24 months after multidisciplinary therapy. It is generally treated by surgery, radiotherapy, and chemotherapy according to the protocols used for other esophageal cancers (EC). However, there is no recommended clinical treatment for ECS because of the rarity of the disease. Esophagectomy with extended lymphadenectomy followed by adjuvant chemotherapy with docetaxel, oxaliplatin, and capecitabine may be recommended treatment for ECS. Chemotherapy regimen with docetaxel, oxaliplatin, and capecitabine may be a suitable adjuvant therapy for ECS." }, { "id": "pubmed23n0787_8559", "title": "The current evidence in support of multimodal treatment of locally advanced, potentially resectable esophageal cancer.", "score": 0.01738934056007227, "content": "Treatment of locally advanced resectable esophageal cancer is challenging. In the past three decades surgical treatment has become safer, chemotherapy more powerful and radiation techniques more precise. Today's stage-dependent treatment relies on modern diagnostic tools such as multidetector helical CT, high-frequency endoscopic ultrasound, PET, image fusion techniques and MRI. Specialists cooperate on multidisciplinary tumor boards that follow transparent decision trees based on the newest evidence. Results of recent randomized controlled trials are examined with emphasis on their reliability and comparability. Patients with esophagogastric cancer undergoing neoadjuvant chemotherapy, perioperative chemotherapy and neoadjuvant radiochemotherapy plus esophagectomy had a higher R-0 resection rate, fewer involved lymph nodes and better overall survival than with esophagectomy alone. While perioperative morbidity and mortality were not remarkably enhanced by neoadjuvant chemotherapy, several trials showed an increase of mortality after neoadjuvant radiochemotherapy. Adenocarcinoma seems to respond better to chemotherapy than squamous cell cancer, and squamous cell cancer seems to respond better to radiochemotherapy than adenocarcinoma. On the basis of the results of randomized trials, preoperative treatment of esophageal cancer shows a survival benefit and should be recommended as the standard treatment strategy in advanced esophageal cancer. While preoperative radiochemotherapy is the standard for advanced squamous cell cancer, both chemotherapy and radiochemotherapy may be adopted for neoadjuvant/perioperative treatment of adenocarcinoma depending on the patient's general condition. Markers to predict response are urgently needed since only responders benefit from multimodal treatment and nonresponders suffer potential harm when surgery is delayed." }, { "id": "pubmed23n0636_20833", "title": "Effects of neoadjuvant radiochemotherapy on pathological staging and prognosis for locally advanced esophageal squamous cell carcinoma.", "score": 0.015109890109890112, "content": "The role of neoadjuvant therapy in the treatment of locally advanced esophageal carcinoma still remains controversial. The aim of this study was to evaluate the effects of neoadjuvant radiochemotherapy on pathological staging and prognosis in the patients with locally advanced esophageal squamous cell carcinoma. Between January 1991 and December 2000, 473 patients with advanced esophageal carcinoma diagnosed by endoscopic biopsy underwent surgical resection in our center. With informed consent, they were randomized into four groups: neoadjuvant chemotherapy, neoadjuvant radiotherapy, neoadjuvant radiochemotherapy, and surgery alone (control group). The preoperative computed tomography staging criteria were the following: Stage I, the tumor limited to the esophageal lumen or the thickness of the esophageal wall varied between 3-5 mm; Stage II, the thickness exceeds 5 mm but no invasion to the mediastinum or distant metastasis; Stage III, the tumor invades adjacent mediastinal structure; and Stage IV, there is distant metastasis. The tumor resection rate, pathological stage, treatment-related complication, and survival among groups were compared. The radical resection rate for the patients in radiotherapy and radiochemotherapy groups was increased in comparison with the control group (P &lt; 0.05). Their pathological stage after esophagectomy was regressed significantly than that of the control group (50.85%, 55.08% vs. 0%, P &lt; 0.05). The adjuvant chemotherapy group did show significant improvement on resection rate and pathological staging compared with the control group. The treatment-related complication in the three neoadjuvant groups had no significant difference from that of the control group (P &gt; 0.05). The 3-year survival rate of radiotherapy and radiochemotherapy groups were significantly higher than that of the control group (69.49%, 73.73% vs. 53.38%, P &lt; 0.05). The 5-year survival rate of radiochemotherapy group was higher than that of the radiotherapy group although did not show a statistical difference (P &gt; 0.05).

He was diagnosed with an esophageal squamous cell carcinoma and referred to our hospital. A type 3 tumor was identified in the lower thoracic esophagus on endoscopy. A CT scan revealed lymph node metastases at the No. 3 station. The clinical stage of the tumor was T3N1M0, Stage III. The patient was treated with neoadjuvant chemotherapy consisting of2 courses of5 -FU and nedaplatin. He had a partial response and underwent a radical esophagectomy. Histopathological examination revealed a complete response of the primary lesion and viable cancer cells in only one lymph node at the No. 3 station. No adjuvant chemotherapy was administered. Three months after the operation, recurrences in the upper abdominal multiple para-aortic lymph nodes were detected. Although he was treated with chemotherapy, he died 7 months after the operation.

The prognosis for recurrent esophageal cancer is generally poor. Recurrences usually occur between 1 and 3 years of surgery, with the duration of median survival after recurrence ranging from 5 to 10 months. The number of sites and involved organs vary among patients. Consequently, a standard therapeutic strategy has not been established, and the role of surgery in the management of recurrence is unclear. A 67-year-old man presented with dysphagia 6 months previously and was diagnosed with esophageal squamous cell carcinoma (ESCC) in the upper thoracic region (T2M0M0, stage IB), for which he underwent thoracoscopy-assisted esophagectomy and lymphadenectomy. Adjuvant chemotherapy was not prescribed. Three years after the operation, he developed a solitary metastasis in the left lung, requiring segmentectomy followed by chemotherapy with combined cisplatin (CDDP) and 5-fluorouracil (5-FU). The following year, a metastatic lesion was recognized in the right lung, invading the chest wall, for which he underwent partial lobectomy with local chest wall resection. Multiple mediastinal and abdominal lymph node (LN) metastases were detected in the right lung a year later, which necessitated chemoradiation to a dose of 50.4 Gy with concomitant CDDP and 5-FU. Post-treatment computed tomography (CT) showed a good response. Positron emission tomography (PET)-CT revealed a reduction in the metastatic LNs with no fluoro-deoxy-glucose (FDG) uptake. The following year, metastases were detected in the left cervical LNs. Owing to the limited extent of metastases, resection was followed by chemoradiation to a dose of 50 Gy with CDDP and 5-FU. The following year, metastases were detected in the mediastinal LNs; chemotherapy was administered with nedaplatin and docetaxel. The follow-up CT and PET-CT demonstrated complete disappearance of the tumor, and the patient is currently surviving without recurrence for 11 years from the first curative operation. This case demonstrates that aggressive multidisciplinary treatment including surgery and radiation to achieve local control could be a meaningful treatment strategy in cases with limited and slowly occurring recurrences." }, { "id": "pubmed23n0314_21509", "title": "[Esophageal cancer].", "score": 0.012699433348068962, "content": "Esophageal cancer is a pathology with a remarkable geographical variety, considered to be a disease of the poor. The common incidence reported in western countries of 3 per 100,000 per year, contrasts with 140 per 100,000 reported in Central Asia in an area that is known as the \"esophageal cancer belt\". Among a wide spectrum of potential etiologic agents, the use of alcohol and tobacco remain the most frequently reported. The most common pathologic type is squamous cell carcinoma, although is important to consider that in the past decades, a shift to adenocarcinoma has been consistently observed. This phenomenon might have an explanation in the inclusion of tumors of the cardia and the importance of metaplasic Barret's epithelium and gastroesophageal reflux. As it happens in the majority of gastrointestinal tumors, diagnosis is often done late in esophageal cancer. The most common presenting symptoms of esophageal cancer are dysphagia and weight loss. Others are, odynophagia, upper GI bleeding, hoarseness and respiratory symptoms. In patients with advanced disease, diagnostic studies are confirmatory in nature. The combined use of contrast esophagogram and endoscopy yield to a diagnostic accuracy above 95%. These studies have to be complimentary. Computed tomography is the best modality for staging tumors of the esophagus. Although its accuracy varies from one study to another, demonstration of disease beyond the esophagus precludes surgical treatment. Endoluminal ultrasound has assumed an important role as part of the staging studies, considered by some authors superior to CT scanning. Its use is not considered rutinary because of the difficulty on passing the instrument through an obstructive lesion, and to the fact that this technology is not widely available. In the majority of patients, surgical treatment is considered to be palliative, due to the presence of advanced disease at the time of diagnosis. From the multiple surgical options available, transhiatal esophagectomy without thoracotomy is one of the more widely accepted techniques. Controversy persists regarding the optimal surgical approach to the disease. It is well accepted that prognosis depends more in the biology of the tumor and the stage of the disease rather than the surgical procedure. Overall five year survival after esophageal resection is 20%, regardless of the surgical option. Other alternatives are standard transthoracic esophagectomy, the thoraco-abdominal approach and the triple approach with extensive lymphadenectomy of cervical, mediastinal and abdominal areas. These latter procedures carry more morbidity and mortality rates. It is probably the multimodality approach with pre or postoperative chemotherapy and radiotherapy what can impact in further improvement of the poor survival rates for this disease. This combined approach is currently being investigated under control prospective randomized trials." }, { "id": "pubmed23n0695_24969", "title": "Curative treatment of oesophageal carcinoma: current options and future developments.", "score": 0.011174579392577332, "content": "Since the 1980s major advances in surgery, radiotherapy and chemotherapy have established multimodal approaches as curative treatment options for oesophageal cancer. In addition the introduction of functional imaging modalities such as PET-CT created new opportunities for a more adequate patient selection and therapy response assessment.The majority of oesophageal carcinomas are represented by two histologies: squamous cell carcinoma and adenocarcinoma. In recent years an epidemiological shift towards the latter was observed. From a surgical point of view, adenocarcinomas, which are usually located in the distal third of the oesophagus, may be treated with a transhiatal resection, whereas squamous cell carcinomas, which are typically found in the middle and the upper third, require a transthoracic approach. Since overall survival after surgery alone is poor, multimodality approaches have been developed. At least for patients with locally advanced tumors, surgery alone can no longer be advocated as routine treatment. Nowadays, scientific interest is focused on tumor response to induction radiochemotherapy. A neoadjuvant approach includes the early and accurate assessment of clinical response, optimally performed by repeated PET-CT imaging and endoscopic ultrasound, which may permit early adaption of the therapeutic concept. Patients with SCC that show clinical response by PET CT are considered to have a better prognosis, regardless of whether surgery will be performed or not. In non-responding patients salvage surgery improves survival, especially if complete resection is achieved." }, { "id": "pubmed23n1139_84", "title": "Predictive Value of Endoscopic Observations and Biopsy After Neoadjuvant Chemoradiotherapy in Assessing the Pathologic Complete Response of Patients With Esophageal Squamous Cell Carcinoma.", "score": 0.01039136302294197, "content": "No standard method has been defined to evaluate the therapeutic response of esophageal cancer to neoadjuvant chemoradiotherapy (CRT). This study aimed to determine the predictive value of endoscopic evaluation and biopsy after CRT in predicting the complete pathological response to neoadjuvant CRT in patients with esophageal squamous cell carcinoma (SCC). This prospective, descriptive study was conducted on patients with stage II and III esophageal SCC who could undergo esophagectomy. Patients underwent neoadjuvant CRT. Four to six weeks after the end of treatment, re-endoscopy was performed and a biopsy was taken in the presence of a tumor lesion. In the absence of a tumor lesion, the marked site of the esophagus was removed as a blind biopsy. Gastrologist observations during endoscopy and the result of the pathological examination of an endoscopic biopsy were recorded. The patient underwent esophagectomy. The pathology obtained from endoscopic biopsy was compared with the pathology response obtained from esophagectomy. Sixty-nine patients were included in the study, of which 32 underwent esophagectomy. In an endoscopic examination after CRT, 28 patients had macroscopic tumor remnants and 4 patients did not. Pathological examination of the samples obtained from endoscopy showed no tumor remnants in 10 patients (31.3%), and in 22 patients (68.7%), living tumor remnants were seen in the biopsy specimen. Pathologic evaluation of the samples obtained by surgical resection showed that in 13 patients, there were no viable carcinomas in the esophagus or lymph nodes removed, and the rate of pathologic complete response was 40.6. Sensitivity, specificity, positive predictive, and negative predictive values of endoscopic observations were 94.7, 23, 64.2, and 75%, respectively. Preoperative biopsy sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 68.4, 30.7, 59, and 40%, respectively.

The development of endoscopic instruments and introduction of fluoro deoxy glucose-positron emission tomography (FDG-PET) and sentinel node (SN) diagnosis markedly improved diagnostic quality. The requirement for individualized treatment is increasing with the progress in less-invasive treatment, and therefore it is necessary to select the optimal treatment individually on the basis of accurate tumor staging. In diagnosis of the T category, zoom endoscopy and autofluorescence imaging/narrow band imaging technology improved the diagnostic accuracy of T1 stage. T2 or higher tumors are diagnosed with endoscopic ultrasonography (EUS) and multidetector computed tomography (CT). In diagnosis of the N category, FDG-PET was expected to be useful. However, it often gave false-negative lymph node (LN) results, and was revealed to have low sensitivity in contrast to high specificity. It is important to detect swollen LNs using CT and then to assess qualitatively the presence or absence of metastasis with EUS and FDG-PET. SN diagnosis using radioisotopes as tracers was introduced as preliminary research for subsequent less-invasive surgery. In diagnosis of the M category, FDG-PET is currently the most important to obtain additional information missed on CT, because FDG-PET can assess the whole body. For response evaluation to neoadjuvant treatment, FDG-PET is extremely useful. It can predict histologic response and postoperative survival accurately and allow diagnosis of distant metastases in the entire body simultaneously. All information needed for a decision on surgical indications can be acquired noninvasively, and therefore FDG-PET may be the key modality in multimodality treatment." }, { "id": "pubmed23n1025_11346", "title": "Radiation-induced hepatitis masquerading as metastatic disease: the importance of correlating diagnostic imaging with treatment planning.", "score": 0.00980392156862745, "content": "We are presenting a 63-year-old Caucasian male who complained of 2 months of progressive dysphagia. Upper endoscopy discovered a mass in the distal esophagus near the gastroesophageal junction. Biopsy was consistent with adenocarcinoma.

Initial positron emission tomography (PET)/computed tomography (CT) showed hypermetabolic portocaval lymphadenopathy presumed to be metastatic, but otherwise without distant disease extension. Neoadjuvant treatment included induction FOLFOX followed by 5,600 cGy over 28 fractions in combination with 5-FU and oxaliplatin. Approximately 3.5 weeks after completion, a repeat PET/CT revealed reduced uptake in both the primary esophageal mass and regional lymph nodes. Of note there were several new mass-like foci of hypermetabolism in the liver, specifically the left lobe, concerning for metastatic disease. Image-guided biopsy did not show any identifiable lesions, but sampling was performed based on anatomical landmarks. Pathology revealed benign parenchyma with minimal inflammation and mild reactive regeneration. In light of this, the patient proceeded to undergo definitive resection via robotic Ivor-Lewis esophagectomy with only 1 positive lymph node. Given pleural involvement by the tumor, staging was revised to pT4aN1 with final histology characterized as adenosquamous carcinoma. Postoperative course was fairly uneventful, with a mild exacerbation of his chronic heart failure. The patient was discharged on post-operative day 7, with his feeding tube removed at his 2-week post-operative clinic visit. This scenario is of particular educational value from the standpoint that when the post-treatment PET/CT images are registered to the radiotherapy treatment planning CT and dose, the areas of abnormal uptake in the liver fall within the higher dose regions. Given this and the liver biopsy findings, caution should be exercised before declaring progressive disease following radiotherapy without first reviewing the treatment plan." }, { "id": "pubmed23n0237_575", "title": "[Current status of esophageal neoplasms.

Preoperative nutritional support may reduce operative mortality and morbidity in high-risk patients. Today there is still no alternative to resection of the carcinoma. Esophagogastrectomy with (cervical) esophagogastrostomy with or without thoracotomy is the treatment of choice for patients with squamous cell carcinoma of the esophagus.

If resection is technically impossible, an endoesophageal tube can be inserted or a bypass procedure carried out to increase the quality of life with near normal ability to swallow. Radiotherapy can be used when surgery primarily is not applicable for medical reasons or is refused.

Twenty-three randomized clinical studies and five meta-analyses were identified. Interpretation--especially of the older studies--however, is hampered by the lack of a stringent application of modern examination techniques allowing for exact specification of tumor stage (resectable/locally advanced) as well as the inclusion of patients with different histological entities (squamous cell/adenocarcinoma), different surgical techniques and the low number of patients.

Median lymph node yield was 19 (10-51) after an Ivor Lewis operation, 16 (3-28) after an open transhiatal operation and 15 (4-41) after a laparoscopic transhiatal operation. There were two in-hospital deaths (5%), both following open Ivor Lewis operation. All patients in the laparoscopic group had N0 disease; none received adjuvant treatment. Two patients (7%) in the open group had N1 disease, of whom one patient received adjuvant chemotherapy. Eleven patients had submucosal invasion. Alive patients had median follow-up of 36 months (range 5-87 months). One patient in the laparoscopic group had recurrence at 22 months. This patient had poorly differentiated N0 disease which was limited to the mucosa and died at 24 months. Two patients in the open group developed recurrence, at 6 months (N0 disease with submucosal invasion) and 8 months (N1 disease with submucosal invasion) and died at 7 and 14 months, respectively. Both patients had poorly differentiated tumours. The second patient with N1 disease is alive and well at 14 months. Estimated survival (Kaplan-Meier) at 3 years was 93%. As compared with open transthoracic esophagectomy, there is no oncological detriment in the treatment of pT1 esophageal adenocarcinoma by laparoscopic transhiatal esophagectomy. The incidence of recurrence is small (7%) but can occur even in patients with tumour limited to the mucosa or N0 disease." }, { "id": "pubmed23n0841_11604", "title": "Accuracy of preoperative diagnosis of lymph node metastasis for thoracic esophageal cancer patients from JCOG9907 trial.", "score": 0.009433962264150943, "content": "Accurate clinical evaluation of lymph nodes is crucial for selection of the optimum treatment strategy for individual esophageal cancer patients.

Fifty-eight patients with carcinoma of the esophagus (46 men and 12 women) with a median age of 61 years underwent FDG-PET imaging of the neck, chest, and abdomen as well as CT of the chest and abdomen. Sensitivity, specificity, and accuracy were calculated for both imaging techniques to evaluate the detection of histologically verified lymph node metastases. The FDG-PET showed higher specificity, whereas CT proved to be more accurate for detecting lymph node metastases not only of the abdomen (73% vs 59%) but also of the thorax (73% vs 63%). Resections were transhiatal in 23 patients and transthoracal in 16. As a supplement to conventional CT diagnostic procedure, FDG-PET was not decisive for the surgical approach. Altogether, pretherapeutical PET imaging did not increase the accuracy of lymph node staging for our patients with esophageal carcinoma, which had already been defined through CT. Therefore, no new consequences resulted for the surgical procedure. Due to the high costs involved with PET investigation, lymph node staging with it is momentarily indicated mainly for clinical studies and when CT does not offer unequivocal results.

Neoadjuvant chemoradiation therapy (CRT) followed by esophagectomy is offered to T2 with positive disease node, T3, and selected T4a disease without metastasis. Relative exclusion criteria for esophagectomy include elderly patients (offered to selected patients) and high-risk patients with comorbid medical conditions. The presence of metastatic disease to other organs or extra-regional lymph nodes is an absolute contraindication to esophagectomy. Surgical procedures are divided accordingly to the anatomical position of esophageal cancer. Cervical esophageal cancer usually requires resection of portions of the larynx, pharynx, thyroid, and proximal esophagus with lower esophagus preservation. Thoracic esophageal cancer will include a total esophagectomy (cervical esophagogastrostomy) with radical two-field lymph node dissection and jejunostomy feeding tube placement. EGJ cancer will involve total esophagectomy and partial or extended gastrectomy. Thoracic cancer resection for the middle to lower esophagus can be divided into three major techniques in the United States: transhiatal, transthoracic (Ivor-Lewis), and tri-incisional esophagectomy. Esophagectomy guidelines recommend at least 15 lymph node resection for adequate staging, and this leads to s significant reduction in mortality (5-year disease-specific survival; 55% less than 11 nodes were resected, 66% for 11 to 17 nodes resected, and 75% more than 18 nodes resected).

The benefit of adjuvant chemoradiation therapy is limited to margin positive and/or node positive patients. There is emerging data questioning the survival benefit of surgical resection after chemoradiotherapy. External beam radiation therapy alone results in very few long-term survivors and is considered palliative at best. Radiation dose-escalation has failed to improve local control or survival. PET scanning is vital in staging and has become a strong predictor of response and survival. Preoperative or definitive concurrent chemoradiotherapy is the established standard of care for locally advanced cancers of the esophagus. While preoperative chemotherapy is supported by level 1 evidence, the true benefit of induction chemotherapy before chemoradiotherapy has not been established in a prospective randomized control trial. The role of surgery in the management of SCC is still a hotly debated subject, however, it is still recommended for AC. There is no data to support adjuvant chemotherapy after preoperative chemoradiotherapy. The benefit of neoadjuvant chemotherapy seems to be limited AC. Radiation without chemotherapy is palliative and never curative.

The treatments for esophageal cancer depend on its etiology. For mucosal cancer, endoscopic mucosal resection and endoscopic submucosal dissection are standard, while for locally advanced cancer, esophagectomy remains the mainstay. The three most common techniques for thoracic esophagectomy are the transhiatal approach, the Ivor Lewis esophagectomy (right thoracotomy and laparotomy), and the McKeown technique (right thoracotomy followed by laparotomy and neck incision with cervical anastomosis). Surgery for carcinoma of the cervical esophagus requires an extensive procedure with laryngectomy in many cases. When the tumor is more advanced, neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy is added. The theoretical advantages of adding chemotherapy to the treatment of esophageal cancer are potential tumor down-staging prior to surgery, as well as targeting micrometastases and, thus, decreasing the risk of distant metastasis. Cisplatin- and 5-fluorouracil-based regimes are used worldwide. Chemoradiotherapy is the standard for unresectable esophageal cancer and could also be considered as an option for resectable tumors. For patients who are medically or technically inoperable, concurrent chemoradiotherapy should be the standard of care. Although neoadjuvant chemoradiotherapy followed by surgery or salvage surgery after definitive chemoradiotherapy is a practical treatment; judicious patient selection is crucial.

For those reasons, a study has been conducted on 52 patients with locally advanced esophagus tumor, who in the first group of 25 patients, were treated only by radiotherapy, and in the second group of 27 patients, by combined radio-chemotherapy. Pretherapy evaluation, evaluation of esophagus stenosis, as well as the tumor regression to conducted treatment, were done in all patients by radiography and endoscopy and the findings were compared: there was no statistically significant difference between investigated methods (p &gt; 0.05). Although bigger number of the tumor complete regressions was verified by radiography (6 in the first group and 5 in the second group of patients) in relation to endoscopic finding (3 in the first group and 2 in the second group of patients), which had no microscopical evidence of remaining disease. Partial tumor regression made greater differences between investigated methods (10:4 in the first group and 6:3 in the second group of patients)." } ] } } }

Asthma treatment algorithm. We rule out continuing with the same treatment since the patient is symptomatic.
A patient diagnosed with bronchial asthma who is being treated with low-dose inhaled steroids (200 micrograms of budesonide every 12 hours) and rescue medication (salbutamol on demand) comes for periodic clinical monitoring. The patient reports that in the last 3 months he has had no exacerbations and that he uses salbutamol once a day. He only has dyspnea when climbing stairs and some nights he sleeps irregularly due to coughing. Which of the following therapeutic options should be considered as the treatment of choice?

This study used a double-blind, double-dummy design to compare the efficacy of 2 treatment approaches: stable dosing of salmeterol/fluticasone propionate (SAL/FP) and AMD of formoterol/budesonide (FOR/BUD). This was a 1-year, multicenter, randomized, double-blind, double-dummy study in adult patients with symptomatic asthma that was not controlled by therapy with 200 to 500 microg/d inhaled corticosteroid (ICS) plus a long-acting beta2 agonist, or with &gt;500 to 1000 microg/d ICS alone. Patients were randomized to receive 1 inhalation of SAL/FP 50/250 microg BID or 2 inhalations of FOR/BUD 6/200 microg BID, both delivered via dry powder inhaler devices. After 4 weeks of stable dosing in both groups, eligible patients continued the study for an additional 48 weeks, receiving either a stable dose of SAL/FP or AMD of FOR/BUD. According to the AMD treatment plan, patients initially halved their dose and subsequently stepped up or down as indicated by the presence or absence of nocturnal awakenings due to asthma, frequency of rescue medication use, and changes in morning peak expiratory flow (PEF). The primary end point was the percentage of symptom-free days. Other parameters included daily asthma symptom scores, morning PEF, percentage of days free of rescue medication use, daily rescue medication use, percentage of nighttime awakenings due to asthma, percentage of weeks with well-controlled asthma, and number of exacerbations requiring oral corticosteroids or emergency department (ED) visits/hospitalizations. Tolerability was assessed in terms of adverse events spontaneously reported or elicited at clinic visits. The intent-to-treat population comprised 688 patients (344 per treatment arm) with a mean age of 45 years and a mean baseline forced expiratory volume in 1 second 81% of the predicted normal value. After 4 weeks' stable dosing, 581 patients (295 SAL/FP, 286 FOR/BUD) continued beyond visit 3 into the remaining 48-week treatment period. Over weeks 1 through 52, patients receiving stable dosing of SAL/FP had a significantly greater percentage of symptom-free days compared with those receiving AMD of FOR/BUD (median, 58.8% vs 52.1%, respectively; P = 0.034). The incidence of asthma exacerbations requiring oral steroids or an ED visit/hospitalization was 47% lower with SAL/FP compared with FOR/BUD (adjusted annual mean rate, 0.18 vs 0.33; P = 0.008). During weeks 5 through 52, patients in the FOR/BUD AMD group used a mean of 1.8 inhalations/d (equivalent to BUD 360 microg/d), and 235 (82.2%) patients stepped down to 1 inhalation/d. Mean (SD) daily ICS exposure over 52 weeks was 463 (81) microg FP and 480 (238) microg BUD in the respective treatment arms. In this adult population with persistent asthma, stable dosing of SAL/FP 50/250 microg BID resulted in significantly greater increases in symptom-free days, days free of rescue medication, and morning PEE, as well as almost halving the exacerbation rate, compared with AMD of FOR/BUD 6/200 microg. The results suggest that there is a minimum daily amount of maintenance therapy necessary to prevent exacerbations in adults with persistent asthma." }, { "id": "pubmed23n0253_4572", "title": "Periodic treatment regimens with inhaled steroids in asthma or chronic obstructive pulmonary disease.

Forty-eight patients with steroid-dependent asthma or COPD who had shown a decline in forced expiratory volume in 1 second (FEV1) of at least 80 mL per year and at least one exacerbation per year during the first 2 years of bronchodilator treatment. Subjects were treated additionally with inhaled steroids for another 2 years and were finally given the option to stop using steroids. Sixteen patients were willing to stop using beclomethasone and were studied for another year. No recruitment bias took place in this consecutive sample in the fifth year of follow-up. Two of 16 patients developed carcinomas and dropped out. Two years of bronchodilator treatment alone (400 micrograms of salbutamol or 40 micrograms of ipratropium bromide four times daily), followed by 2 years of additional inhaled corticosteroid treatment (400 micrograms of beclomethasone two times daily), and finally 1 year of bronchodilator treatment alone. Decline in lung function (FEV1), change in bronchial hyperresponsiveness, indicated by a provocative concentration of histamine causing a 20% fall in FEV1 (PC20), morning peak expiratory flow rate (PEFR), diurnal PEFR, week-to-week variation of PEFR, bronchial symptoms, and exacerbations. The course of FEV1 during the year in which beclomethasone was discontinued was not significantly different when compared with the 2-year period of beclomethasone treatment. Neither did the course of PC20, morning PEFR, diurnal PEFR, symptom score, and exacerbation rate change. Only the week-to-week variation of the PEFR increased after discontinuing steroids. Discontinuing inhaled steroids is possible in some patients with asthma or COPD after 2 years of regular treatment. This might indicate that for certain groups of patients with mild asthma or COPD, periodic treatment schedules with inhaled steroids is the treatment policy for the future." }, { "id": "pubmed23n0658_10806", "title": "Addition of long-acting beta2-agonists to inhaled steroids versus higher dose inhaled steroids in adults and children with persistent asthma.", "score": 0.015424311926605505, "content": "In asthmatic patients inadequately controlled on inhaled corticosteroids and/or those with moderate persistent asthma, two main options are recommended: the combination of a long-acting inhaled ss2 agonist (LABA) with inhaled corticosteroids (ICS) or use of a higher dose of inhaled corticosteroids. To determine the effect of the combination of long-acting ss(2) agonists and inhaled corticosteroids compared to a higher dose of inhaled corticosteroids on the risk of asthma exacerbations, pulmonary function and on other measures of asthma control, and to look for characteristics associated with greater benefit for either treatment option. We identified randomised controlled trials (RCTs) through electronic database searches (MEDLINE, EMBASE and CINAHL), bibliographies of RCTs, clinical trial registries and correspondence with manufacturers until May 2008. RCTs that compared the combination of inhaled LABA and ICS to a higher dose of inhaled corticosteroids, in children and adults with asthma. Two authors independently assessed methodological quality and extracted data. We obtained confirmation from the trialists when possible. The primary endpoint was the number of patients experiencing one or more asthma exacerbations requiring oral corticosteroids. This review included 48 studies (15,155 participants including 1155 children and 14,000 adults). Participants were inadequately controlled on their current ICS regimen, experiencing ongoing symptoms and with generally moderate (FEV1 60% to 79% of predicted) airway obstruction. The studies tested the combination of salmeterol or formoterol with a median dose of 400 mcg/day of beclomethasone or equivalent (BDP-eq) compared to a median of 1000 mcg/day of BDP-eq, usually for 24 weeks or less. There was a statistically significantly lower risk of exacerbations requiring systemic corticosteroids in patients treated with LABA and ICS (RR 0.88, 95% CI 0.78 to 0.98, 27 studies, N = 10,578) from 11.45% to 10%, with a number needed to treat of 73 (median study duration: 12 weeks). The study results were dominated by adult studies; trial data from three paediatric studies showed a trend towards increased risk of rescue oral steroids (RR 1.24, 95% CI 0.58 to 2.66) and hospital admission (RR 2.21, 95% CI 0.74 to 6.64) associated with combination therapy. Overall, there was no statistically significant difference in the risk ratios for either hospital admission (RR 1.02, 95% CI 0.67 to 1.56) or serious adverse events (RR 1.12, 95% CI 0.91 to 1.37). The combination of LABA and ICS resulted in significantly greater but modest improvement from baseline in lung function, symptoms and rescue medication use than with higher ICS dose. Despite no significant group difference in the risk of overall adverse events (RR 0.99, 95% CI 0.95 to 1.03), there was an increase in the risk of tremor (RR 1.84, 95% CI 1.20 to 2.82) and a lower risk of oral thrush (RR 0.58, 95% CI 0.40 to 0.86)) in the LABA and ICS compared to the higher ICS group. There was no significant difference in hoarseness or headache between the treatment groups. The rate of withdrawals due to poor asthma control favoured the combination of LABA and ICS (RR 0.65, 95% CI 0.51 to 0.83). In adolescents and adults with sub-optimal control on low dose ICS monotherapy, the combination of LABA and ICS is modestly more effective in reducing the risk of exacerbations requiring oral corticosteroids than a higher dose of ICS. Combination therapy also led to modestly greater improvement in lung function, symptoms and use of rescue ss(2) agonists and to fewer withdrawals due to poor asthma control than with a higher dose of inhaled corticosteroids. Apart from an increased rate of tremor and less oral candidiasis with combination therapy, the two options appear relatively safe in adults although adverse effects associated with long-term ICS treatment were seldom monitored. In children, combination therapy did not lead to a significant reduction, but rather a trend towards an increased risk, of oral steroid-treated exacerbations and hospital admissions. These trends raised concern about the safety of combination therapy in view of modest improvement in children under the age of 12 years." }, { "id": "pubmed23n0554_8143", "title": "Long-acting beta2-agonists versus anti-leukotrienes as add-on therapy to inhaled corticosteroids for chronic asthma.", "score": 0.015006385696040868, "content": "Patients who continue to experience asthma symptoms despite taking regular inhaled corticosteroids (ICS) represent a management challenge.

The combination of formoterol and budesonide in a single inhaler introduces the possibility of using a single inhaler for both prevention and relief of symptoms (single inhaler therapy). The aim of this review is to compare formoterol and corticosteroid in single inhaler for maintenance and relief of symptoms with inhaled corticosteroids for maintenance and a separate reliever inhaler. We last searched the Cochrane Airways Group trials register in September 2008. Randomised controlled trials in adults and children with chronic asthma. Two review authors independently assessed studies for inclusion and extracted the characteristics and results of each study. Authors or manufacturers were asked to supply unpublished data in relation to primary outcomes. Five studies on 5,378 adults compared single inhaler therapy with current best practice, and did not show a significant reduction in participants with exacerbations causing hospitalisation (Peto OR 0.59; 95% CI 0.24 to 1.45) or treated with oral steroids (OR 0.83; 95% CI 0.66 to 1.03). Three of these studies on 4281 adults did not show a significant reduction in time to first severe exacerbation needing medical intervention (HR 0.96; 95% CI 0.85 to 1.07). These trials demonstrated a reduction in the mean total daily dose of inhaled corticosteroids with single inhaler therapy (mean reduction ranged from 107 to 267 micrograms/day, but the trial results were not combined due to heterogeneity). The full results from four further studies on 4,600 adults comparing single inhaler therapy with current best practice are awaited.Three studies including 4,209 adults compared single inhaler therapy with higher dose budesonide maintenance and terbutaline for symptom relief. No significant reduction was found with single inhaler therapy in the risk of patients suffering an asthma exacerbation leading to hospitalisation (Peto OR 0.56; 95% CI 0.28 to 1.09), but fewer patients on single inhaler therapy needed a course of oral corticosteroids (OR 0.54; 95% CI 0.45 to 0.64). These results translate into an eleven month number needed to treat of 14 (95% CI 12 to 18), to prevent one patient being treated with oral corticosteroids for an exacerbation. The run-in for these studies involved withdrawal of long-acting beta(2)-agonists, and patients were recruited who were symptomatic during run-in.One study included children (N = 224), in which single inhaler therapy was compared to higher dose budesonide. There was a significant reduction in participants who needed an increase in their inhaled steroids with single inhaler therapy, but there were only two hospitalisations for asthma and no separate data on courses of oral corticosteroids. Less inhaled and oral corticosteroids were used in the single inhaler therapy group and the annual height gain was also 1 cm greater in the single inhaler therapy group, [95% CI 0.3 to 1.7 cm].There was no significant difference found in fatal or non-fatal serious adverse events for any of the comparisons. Single inhaler therapy can reduce the risk of asthma exacerbations needing oral corticosteroids in comparison with fixed dose maintenance inhaled corticosteroids. Guidelines and common best practice suggest the addition of regular long-acting beta(2)-agonist to inhaled corticosteroids for uncontrolled asthma, and single inhaler therapy has not been demonstrated to significantly reduce exacerbations in comparison with current best practice, although results of five large trials are awaiting full publication.

In addition there has been an intense debate about the regular use of these drugs. This debate is reviewed. They should only be used on \"as needed basis\". The Swedish guidelines for the treatment of asthma were the first to recommend the new long-acting inhaled beta 2-adrenoceptor agonists at relatively early stage of the illness (800 micrograms daily of inhaled corticosteroids). Two recently completed large multicentre studies with salmeterol in asthmatics support this opinion. Both studies showed a better asthma control with a combination of a low inhaled steroid dose and salmeterol compared to a doubling of the steroid dose. In most asthmatic patients, still symptomatic on inhaled steroids doses 400 to 800 micrograms daily, a test of the addition of inhaled salmeterol is recommended.

Long-acting muscarinic antagonists (LAMA) are a class of inhaled drug which have been effective for people with chronic obstructive pulmonary disease and are now becoming available for people with asthma to take alongside their LABA/ICS inhaler. To assess the effects of adding a long-acting muscarinic antagonist (LAMA) to combination long-acting beta2-agonists (LABA) and inhaled corticosteroids (ICS) in adults whose asthma is not well controlled by LABA/ICS. We identified trials from the Cochrane Airways Review Group Specialised Register (CAGR) up to January 2016. We also searched ClinicalTrials.gov, the WHO trials portal, and reference lists of other reviews, and we contacted trial authors for additional information. We included parallel randomised controlled trials (RCTs) of at least 12 weeks' duration. Studies met the inclusion criteria if they compared LAMA as an add-on to LABA/ICS versus LABA/ICS alone for adults with asthma. We included studies reported as full text, those published as abstract only, and unpublished data. Primary outcomes were exacerbations requiring oral corticosteroids (OCS), validated measures of asthma control, and serious adverse events (including mortality). Two review authors screened searches and independently extracted details on risk of bias and numerical data. We analysed dichotomous data as odds ratios (ORs) and continuous data as mean differences (MD) using a random-effects model. We rated all outcomes using GRADE. We found four double-blind, double-dummy trials comparing LAMA to placebo, including 1197 people with asthma taking combination LABA/ICS. One of the trials was designed to study glycopyrronium bromide but was withdrawn prior to enrolment, and the other three all studied tiotropium bromide (mostly 5 µg once daily via Respimat) over 48 to 52 weeks. People in the trials had a mean forced expiratory volume in one second (FEV1) of 55% of their predicted value, indicating severe asthma.People randomised to take tiotropium add-on had fewer exacerbations requiring oral corticosteroids than those continuing to take LABA/ICS alone, but the confidence intervals did not rule out no difference (OR 0.76, 95% CI 0.57 to 1.02; moderate quality evidence). Over 48 weeks, 328 out of 1000 people taking their usual LABA/ICS would have to take oral corticosteroids for an exacerbation compared with 271 if they took tiotropium as well (95% CI 218 to 333 per 1000). Analyses comparing the number of exacerbations per patient in each group (rate ratio) and the time until first exacerbation (hazard ratio) were in keeping with the main result. Quality of life, as measured by the Asthma Quality of Life Questionnaire (AQLQ) was no better for those taking tiotropium add-on than for those taking LABA/ICS alone when considered in light of the 0.5 minimal clinically important difference on the scale (MD 0.09, 95% CI - 0.03 to 0.20), and evidence for whether tiotropium increased or decreased serious adverse events in this population was inconsistent (OR 0.60, 95% CI 0.24 to 1.47; I(2) = 76%).Within the secondary outcomes, exacerbations requiring hospital admission were too rare to tell whether tiotropium was beneficial over LABA/ICS alone. There was high quality evidence showing benefits to lung function (trough FEV1 and forced vital capacity (FVC)) and potentially small benefits to asthma control. People taking tiotropium add-on were less likely to experience non-serious adverse events. Tiotropium add-on may have additional benefits over LABA/ICS alone in reducing the need for rescue oral steroids in people with severe asthma. The effect was imprecise, and there was no evidence for other LAMA preparations. Possible benefits on quality of life were negligible, and evidence for the effect on serious adverse events was inconsistent. There are likely to be small added benefits for tiotropium Respimat 5 µg daily on lung function and asthma control over LABA/ICS alone and fewer non-serious adverse events. The benefit of tiotropium add-on on the frequency of hospital admission is still unknown, despite year-long trials.Ongoing and future trials should clearly describe participants' background medications to help clinicians judge how the findings relate to stepwise care. If studies test LAMAs other than tiotropium Respimat for asthma, they should be at least six months long and use accepted and validated outcomes to allow comparisons of the safety and effectiveness between different preparations." }, { "id": "pubmed23n0521_11765", "title": "As-needed inhaled beta2-adrenoceptor agonists in moderate-to-severe asthma: current recommendations.", "score": 0.011117955035417309, "content": "Intermediate-acting inhaled beta2-agonists (e.g. albuterol [salbutamol]), once recommended for round-the-clock bronchodilation, are now recommended to be used exclusively as-needed. Guidelines advise that asthma should be controlled with anti-inflammatory therapeutic strategies so that the as-needed requirement for inhaled beta2-agonists should be infrequent; ideally less than several times per week, up to once a day for exercise, and none at night. These recommendations are based upon the recognition that asthma is primarily an inflammatory condition and that the major thrust of therapy should be anti-inflammatory, including environmental control and administration of inhaled corticosteroids (ICS), leukotriene-receptor antagonists, and possibly oral theophylline and inhaled cromones; the cromones include cromolyn sodium (sodium cromogylcate) and nedocromil. While this is the primary rationale behind the as-needed infrequent prescription of the inhaled beta2-agonist paradigm, there are a number of detrimental effects that can be seen with regularly scheduled (or frequent as-needed) use of inhaled beta2-agonists. These include tolerance to the bronchodilator and particularly the bronchoprotective effects, increased airway responsiveness to allergen, worsened asthma control, and, probably most importantly, over-reliance on an excellent symptom reliever leading to undertreatment. Any or all of these could be responsible for the demonstrated dose-response relationship between inhaled beta2-agonist overuse and death from asthma. Several controlled clinical trials, which have included many patients with at least moderately severe asthma, have failed to demonstrate any obvious advantage to the regular scheduled use of inhaled beta2-agonists compared with as-needed inhaled beta2-agonists. On the other hand, despite no obvious advantage, regular use of albuterol 1000-1200 microg/day appears to be well tolerated and reasonably safe. When asthma is treated using an as-needed, infrequent inhaled beta2-agonist, the requirements for beta2-agonists become a useful marker of whether or not the asthma is adequately controlled. When inhaled beta2-agonists are required inordinately frequently (i.e. when asthma is not adequately controlled), after ensuring compliance with ICS, the most common strategy is to add one of the long-acting inhaled beta2-agonists twice daily. On the basis of the available evidence, the as-needed intermediate-acting inhaled beta2-agonist therapeutic strategy appears appropriate for patients with moderate-to-severe asthma." }, { "id": "pubmed23n0381_22605", "title": "Clinical outcome of adding long-acting beta-agonists to inhaled corticosteroids.", "score": 0.010968592663629824, "content": "Current asthma management guidelines state that where a patient is receiving a low to moderate dose of inhaled corticosteroids and is still experiencing symptoms the dose of corticosteroid should be increased and, if necessary, a long-acting bronchodilator should be added. Many studies have now shown that the addition of a beta2-agonist with long-acting properties is more effective at controlling asthma symptoms than increasing the dose of corticosteroid alone. The Formoterol and Corticosteroid Establishing Therapy (FACET) study was a 12-month study comparing exacerbation rates in patients treated with budesonide (100 microg or 400 microg) twice daily alone vs, treatment with budesonide (100 microg or 400 microg) twice daily plus formoterol 9 microg twice daily (delivered dose). The addition of formoterol reduced the rates of mild and severe exacerbations compared with budesonide alone, with the lowest rates seen in patients receiving high-dose budesonide and formoterol. There was no difference in the profile of exacerbations in any groups, indicating formoterol does not mask any signs of inflammation. The addition of formoterol to budesonide was also shown to result in improved lung function (as measured by peak expiratory flow rate and forced expiratory volume in 1 second), night-time awakenings and the use of as-needed medication when compared with an increase in the dose of budesonide. In all cases, increasing the dose of budesonide and addition of formoterol resulted in the most improvement and a significant increase in quality of life, measured by Asthma Quality of Life Questionnaire (AQLQ), was noted.

Bronchodilation is significant within minutes of inhalation, maximal within 2 hours, and at therapeutic doses is equivalent to that produced by standard doses of traditional beta 2-agonists. In single-dose studies comparing the two long-acting beta 2-agonists formoterol and salmeterol, significant bronchodilation is achieved more rapidly with formoterol than salmeterol. Duration of bronchodilation is similar with both drugs. The therapeutic efficacy of inhaled formoterol has been equal to or greater than that of salbutamol (albuterol), fenoterol and terbutaline in both short and long term clinical trials. Formoterol reduces symptoms of nocturnal asthma and reduces the need for rescue medication compared with salbutamol. Recent studies have shown that the addition of inhaled formoterol 12 or 24 micrograms twice daily to existing inhaled corticosteroid regimens improves lung function and reduces asthma symptoms compared with placebo. In one well designed study, the frequency of severe exacerbations of asthma over 12 months was decreased by adding formoterol to existing regimens of inhaled corticosteroids. Tolerance to the bronchodilator response of formoterol has not been observed in long term clinical trials. Because of its long duration of action, formoterol offers significant therapeutic advantages over shorter-acting beta 2-agonists in the treatment of nocturnal and exercise-induced asthma. Formoterol is effective in preventing exercise-induced asthma in adults and children and confers significantly more protection than salbutamol when administered 3 and 12 hours before exercise. In general, inhaled formoterol is well tolerated. The most commonly reported adverse effects, tremor and palpitations, are those traditionally associated with the use of beta 2-agonists.

Studies were assessed independently by two review authors for methodological quality and data extraction. Confirmation was obtained from the trialists when possible. The primary endpoint was rate of asthma exacerbations requiring systemic corticosteroids. Secondary endpoints included pulmonary function tests (PFTs), symptom scores, adverse events and withdrawal rates. Of 594 identified citations, 49 trials met the inclusion criteria: 27 full-text publications, one unpublished full-text report and 21 abstracts. Twenty-three citations (21 abstracts and two full-text publications) provided data in insufficient detail, 26 trials contributed to this systematic review. All but three trials were of high methodological quality. Most interventions (N = 26) were of four-month duration or less. Eight trials focused on children and 18 on adults, with participants generally symptomatic with moderate airway obstruction despite their current inhaled steroid regimen. If a trial had more than one intervention or control group, additional control to intervention comparisons were considered separately. Formoterol (N = 17) or salmeterol (N = 14) were most frequently added to low-dose inhaled corticosteroids (200 to 400 microg/day of beclomethasone (BDP) or equivalent). The addition of a daily long-acting beta2-agonist (LABA) reduced the risk of exacerbations requiring systemic steroids by 19% (relative risk (RR) 0.81, 95% CI 0.73 to 0.90). The number needed to treat for one extra patient to be free from exacerbation for one year was 18 (95% CI 13 to 33). The addition of LABA significantly improved FEV1 (weighted mean difference (WMD) 170 mL, 95% CI 110 to 240) using a random-effects model, increased the proportion of symptom-free days (WMD 17%, 95% CI 12 to 22, N = 6 trials) and rescue-free days (WMD 19%, 95% CI 12 to 26, N = 2 trials). The group treated with LABA plus inhaled corticosteroid showed a reduction in the use of rescue short-acting beta2-agonists (WMD -0.7 puffs/day, 95% CI -1.2 to -0.2), experienced less withdrawals due to poor asthma control (RR 0.5, 95% CI 0.4 to 0.7) and less withdrawals due to any reason (RR 0.9, 95% CI 0.8 to 0.98), using a random-effects model. There was no group difference in risk of overall adverse effects (RR 0.98, 95% CI 0.92 to 1.05), withdrawals due to adverse health events (RR 1.29, 95% CI 0.96 to 1.75) or specific adverse health events. In patients who are symptomatic on low to high doses of inhaled corticosteroids, the addition of a long-acting beta2-agonist reduces the rate of exacerbations requiring systemic steroids, improves lung function, symptoms and use of rescue short-acting beta2-agonists. The similar number of serious adverse events and withdrawal rates in both groups provides some indirect evidence of the safety of long-acting beta2-agonists as add-on therapy to inhaled corticosteroids." }, { "id": "pubmed23n0334_10545", "title": "Comparison of salmeterol with beclomethasone in adult patients with mild persistent asthma who are already on low-dose inhaled steroids.", "score": 0.009615384615384616, "content": "Current guidelines on asthma management recommend the early use of inhaled corticosteroids. Recent studies of patients with moderate to severe asthma show that the addition of salmeterol is superior to a further increase of the steroids.

(both via Diskhaler dry powder inhaler) to the low-dose inhaled steroids. A double-blind, randomized, parallel-group study was conducted with a run-in period of 2 weeks and a treatment period of 12 weeks. Patients (n = 233) were randomized with a peak expiratory flow (PEF) reversibility of 22 +/- 10% (mean +/- SD) in the run-in period. The morning PEF was 84 +/- 17% predicted and the age was 42 +/- 14 years (45% males). The average prestudy inhaled steroid dose was 361 microg daily. Within a week of salmeterol treatment the daily PEF recordings reached maximal levels. At the end of the treatment period the evening PEF remained significantly better in the salmeterol group than in the BDP group (p = 0.036). The PEFs, measured at the general practitioners' (GPs') office, were at least 95% of the predicted values and the post-salbutamol values at the end of both treatments. However, the salmeterol group had already obtained this level after 2 weeks and differed significantly from the beclomethasone group (p = 0.003 for percent predicted and p = 0.0007 for post-salbutamol PEF values). The symptom scores and the use of rescue medication showed a similar profile. Quality of life improved with both treatments, but without significant statistical differences between the groups. The frequency of adverse events, typical for beta2-agonists, was low and showed no differences between the groups. These results showed that the addition of salmeterol is at least as effective as adding beclomethasone in normalizing peak flows and improving asthma control in mild persistent asthma patients. Furthermore, salmeterol has a much faster onset of action." }, { "id": "pubmed23n0284_4019", "title": "[Comparative study] of beclomethasone and budesonide, with same posology (400 micrograms every 12 hours), in the control of cortico-dependent intrinsic asthma].", "score": 0.009523809523809525, "content": "Inhaled steroids have rendered an undoubtful benefit in the control of airway inflammation of the asthmatic patients.

Today, the combination of long-acting β2-agonists (LABA) and inhaled glucocorticoids are the first choice of therapy, with or without the presence of reversibility, in patients with airway obstruction. We aimed to compare the efficacy of salbutamol and long acting β2-agonists plus inhaled glucocorticoids for early reversibility test in patients with airway obstruction. Symptomatic patients (cough, dyspnea, and/or wheezing) with airway obstruction according to pulmonary function testing (FEV1/FVC value less than 70% of expected) who had never used bronchodilators before or had not received short- or long-acting inhaled bronchodilator therapy within the most recent 12 hours were evaluated. Reversibility measurements were made by administering the combination of long-acting β2-agonists (LABA) and inhaled glucocorticoids after 15 minutes. A total of 90 patients were evaluated. The mean age of patients was 57.3±17.7 (range, 8-88) years and the male-to-female ratio was 69/21. The baseline pulmonary function test results were mean FVC; 2,747±1,181 mL and 74.7%±21.4%, mean FEV1; 1,716±825 mL and 57.5%±19.0%, mean FEV1/FVC; 61.4%±7.4%. The bronchodilator drugs given before reversibility testing were as salmeterol/fluticasone (FTC/SAL), formoterol/budesonide (BUD/FOR), beclomethasone dipropionate/formoterol (BDP/FOR) and salbutamol (SLB) in 24, 22, 24 and 20 patients, respectively.

There was no statistically significant for reversibilty results between LABAs/inhaledsteroids and SLB group.

We think that performance of an early reversibility test using the combination of a LABA and an inhaled corticosteroid for treatment would enhance both the education of the patient in using the device and the reliability of the drug.

How many of these patients have a response and how the response to beta agonists relates to the response to corticosteroids is not clear. In 127 outpatients (mean (SD) FEV1 0.92 (0.38) 1) who had a clinical diagnosis of chronic obstructive lung disease (continuous breathlessness for more than six months and an FEV1/forced vital capacity (FVC) ratio less than 60%) and who appeared to be stable, the change in FEV1 was measured after salbutamol 200 micrograms from a metered dose inhaler and 5 mg from a nebuliser. Symptoms and spirometric values were recorded before and after two weeks of oral prednisolone 30 mg. Reversibility was defined as a response in FEV1 of 15% or more from baseline alone and as a 15% change and a minimum increase of at least 200 ml. The latter gave results that showed greater internal consistency between the drug regimens. On the basis of this criterion 56 patients (44%) had no response to salbutamol or prednisolone, 71 responded to salbutamol (including all 27 steroid responders), and 25 patients had a response to salbutamol 5 mg but not to 200 micrograms. In general, the largest increase in FEV1 after salbutamol occurred in the subjects with greatest improvement after prednisolone. Subjects showing a response in FEV1 after two weeks' prednisolone had a fall in total symptom score, unlike those who had no response to any treatment or a response to salbutamol only. These data show that reversibility in response to beta agonists is common in patients diagnosed on clinical grounds as having stable chronic obstructive lung disease, that it can be substantial, and that it is best detected by using a larger dose of salbutamol. Salbutamol responders were those most likely to improve after a trial of oral prednisolone. Allowance should be made for the variability of FEV1 in the calculation of the percentage response at low baseline values (less than 1 litre)." } ] } } }

The natural history of idiopathic scoliosis is a crucial issue in the planning and assessment of different treatment methods. This article presents the evaluation of scoliotic deformity in immature patients who have been in observation without any treatment. Material and methods. 159 patients (128 girls, 31 boys) were examined between 1971 and 2002. Skoliosis was diagnosed at a mean age of 6 years 4 months (range 2.1-8.10), and observation was concluded at a mean age of 16 years 11 months (range 14.6-20.3). The mean follow-up was 10 years 5 months. The prognostic factors analyzed were: age, sex, Cobb angle, Mehta angle, apical vertebral rotation, specific rotation, Risser test. The progression and regression of curvature was analyzed in different biological age periods, and was measured by calculating the difference in the Cobb angle on successive x-rays divided by the interval between x-rays. Results. The mean progression of curvature before age 5 was 5.7 degrees per year; in the 6-10 age bracket, 2.3 degrees per year; in the 11-15 age bracket, 7.4 degrees per year; in the &gt;15 age bracket, 0.3 degrees per year. The mean progression for patients with Risser 1 was 8.8 degrees per year; Risser 2, 7.3 degrees per year; Risser 3, 5.1 per year; Risser 4, 2.1 degrees per year; Risser 5, 0.3 degrees per year. Conclusions. The progression of curvature in idiopathic scoliosis is variable, and is influenced by age. Knowledge of the natural history of idiopathic scoliosis is a crucial tool in predicting the development of spinal curvature. The Risser test and biological age are the only effective predictors of progression." }, { "id": "pubmed23n0726_2853", "title": "Effectiveness of the Charleston night-time bending brace in the treatment of adolescent idiopathic scoliosis.", "score": 0.01779500158177792, "content": "Part-time or night-time bracing has been introduced to address the poor compliance and psychological burden of full-time bracing.

Patient demographics, age at detection, family history, clinical and radiological charts of consecutive patients referred for scoliosis evaluation during the period 2003-2011, were prospectively registered. Patients were recruited from a catchment area of about 500000 teenagers. Maturity was estimated according to Risser sign and menarcheal status. Severity of pain was recorded by a verbal 5-point scale from no pain to pain at all times. Physical and neurological examinations were conducted. The detector and patient characteristics were recorded. Referral patterns of orthopedic surgeons at local hospitals and other health care providers were recorded. Patient data was obtained by spine surgeons. Treatment modalities in the current period were compared to the period 1976-1988. We registered 752 patients with late onset juvenile and adolescent idiopathic scoliosis from 2003-2011. There were 644 (86%) girls and 108 (14%) boys. Mean age at detection was 14.6 (7-19) years. Sixty percent had Risser sign ≥ 3, whilst 74% were post menarche with a mean age at menarche of 13.2 years. Thirty-one percent had a family history of scoliosis. The mean major curve at first consultation at our clinic was 38° (10°-95°). About 40% had a major curve &gt;40°. Seventy-one percent were detected by patients, close relatives, and friends. Orthopaedic surgeons referred 61% of the patients. The mean duration from detection to the first consultation was 20(0-27) months. The proportion of the average number of patients braced each year was 68% during the period with screening compared to 38% in the period without screening, while the proportion for those operated was 32% and 62%, respectively ( p=0.002, OR 3.5, (95%CI 1.6 to 7.5). In the absence of scoliosis screening, lay persons most often detect scoliosis. Many patients presented with a mean Cobb angle approaching the upper limit for brace treatment indications. The frequency of brace treatment has been reduced and surgery is increased during the recent period without screening compared with the period in the past when screening was still conducted." }, { "id": "pubmed23n0730_6128", "title": "Bracing can reduce high degree curves and improve aesthetics immediately after the end of growth.

A Case Control Study with Bracing.", "score": 0.011786600496277916, "content": "<bBackground</b: The most common conservative treatment for Adolescent Idiopathic Scoliosis (AIS) is bracing. However, several papers questioned the effectiveness of bracing for curves between 40° and 50° Cobb: the effectiveness in preventing curve progression could be as low as 35%. Seriate casting is considered a standard approach in early onset scoliosis; however, in the setting of AIS, cast treatment is seldom utilized, with only few studies reporting on its effectiveness. <bAim of the study:</b The main aim of the study is to determine whether a seriate casting with Risser casts associated with bracing is more effective in preventing curve progression than bracing alone in curves larger than 40°. Furthermore, the secondary endpoints were: (1) is there a difference in effectiveness of casting between Thoracic (T) and Thoracolumbar/Lumbar (TL/L) curves? (2) Does the 'in cast' correction predicts the treatment outcome? (3) What is the effect on thoracic kyphosis of casting? <bMethods</b: This is a retrospective monocentric case-control study; through an Institutional Database search we identified all the patients treated at our institution between 1 January 2017 and 31 December 2020, with a diagnosis of AIS, Risser grade between 0 and 4 at the beginning of the treatment, at least one curve above 40° Cobb and treatment with either seriate Risser casting and bracing (Study Group, SG) or bracing alone (Control Group, CG). Standing full spine X-rays in AP and LL are obtained before and after the cast treatment; only AP standing full spine X-rays 'in-cast' are obtained for each cast made. Patients were stratified according to the curve behavior at the end of treatment (Risser 5): progression was defined as ≥6° increase in the curve magnitude or fusion needed; stabilization is defined as a change in curve by ±5°; and improvement was defined as ≥6° reduction in the curve. <bResults</b: For the final analysis, 55 compliant patients (12 M, 43 F, mean age 13.5 ± 1.6) were included in the SG and 27 (4 M, 23 F, mean age 13.6 ± 1.6) in the CG. Eight (14.5%) patients in the SG failed the conservative treatment while 14 (51.3%) failed in the CG. Consequently, the Relative Risk for progression in the Efficacy Analysis was 1.8 (95% CI 1, 3-2.6, <ip</i = 0.001), and the Number Needed to Treat was 2,4. No significant difference was found between the T and TL/L curves concerning the 'progressive' endpoint (z-score 0.263, <ip</i = 0.79). The mean percentage of 'in cast' curve reduction was 40.1 ± 15.2%; no significant correlation was found between the percentage of correction and the outcome (Spearman Correlation Coefficient 0.18). Finally, no significant differences between baseline and end of FU TK were found (32° ± 16.2 vs. 29.6 ± 15.8, <ip</i = ns). <bDiscussion:</b Seriate Risser casting for AIS with larger curves (&amp;gt;40° Cobb) is effective in reducing curve progression when compared with full time bracing alone in treatment compliant patients. The treatment is equally effective in controlling T and TL/L curves; furthermore, a slight but non-significant decrease in TK was observed in patients treated with casting. This type of treatment should be considered for AIS patients who present with large curves to potentially reduce the percentage of surgical cases. <bShort Abstract</b: The aim of the study is to determine whether seriate Risser casting associated with bracing is more effective in preventing curve progression than bracing alone in curves larger than 40°. This is a retrospective monocentric case-control study; we identified all the patients treated at our institution with a diagnosis of AIS, Risser grade 0-4 at the beginning of the treatment, at least one curve above 40° Cobb (35° if treated with bracing alone) and treatment with either seriate Risser casting and bracing (Study Group, SG) or bracing alone (Control Group, CG). Fifty-five patients (12 M, 43 F, mean age 13.5 ± 1.6) were included in the SG and 30 (5 M, 25 F, mean age 13.9 ± 1.7) in the CG. Eight (14,5%) patients in the SG failed the conservative treatment while fifteen (50%) failed in the CG. Consequently, the Relative Risk for progression in the Efficacy Analysis was 1.8 (95% CI 1.3-2.6, <ip</i = 0.001), and the Number Needed to Treat was 2,4.

These patients formed the questionnaire sample for the worst-case analysis showing that the progression rate of the 181 patients from the preliminary study and the 116 patients of the questionnaire sample together was still better than natural history even if all drop-outs were considered to be failures. The fact that there was no relative progression in our patients sample treated solely by physiotherapy (preliminary study), seems to show the effectiveness of the inpatient rehabilitation programme even in cases with a bad prognosis, severe angles of curvature and unfavourable curvature patterns. A worst-case analysis does not prevent this conclusion, even if all dropouts from the non-repeaters group were considered as failures." }, { "id": "pubmed23n0548_4535", "title": "[Is it too late to start orthopedic treatment for idiopathic scoliosis with Risser scores of 4?].", "score": 0.011393429357501214, "content": "Orthopaedic treatment for idiopathic scoliosis in adolescence is indicated with a curve of &gt; or =20 degrees and a Risser score&lt; or =4, because progression of curve is low with Risser scores &gt;4.

Consequently, in curves more than 45°, fusion is considered as basically the only possible treatment. The purpose of the study was to verify in a series of patients who utterly refused surgery if it was possible to achieve improvements of scoliosis of more than 45° through a complete conservative treatment (bracing and exercises). Retrospective cohort from a prospective database. Out of 1,148 idiopathic scoliosis (IS) patients at the end of treatment, the sample comprised 28 subjects older than 10 years, still growing, with at least one curve above 45°, who had continually refused fusion. The group comprised 24 females and four males, including 14 in which previous brace treatments had failed; at the start of treatment, the age was 14.2±1.8 years and Cobb degrees in the curve were 49.4° (range, 45°-58°). Subgroups considered were gender, bone age, type of scoliosis, treatment used, and previous failed treatment. Self-report measurement: SRS-22; physiological measures: Cobb degrees, Bunnell angle of trunk rotation (ATR), aesthetic index (AI), and sagittal plumb line distances. The methods comprised full-time treatment (23 or 24 hours per day) for 1 year with Risser cast, Lyon, or Sforzesco brace; weaning of 1 to 2 hours every 6 months; with strategies to maximize compliance through the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) management criteria applied and specific scientific exercises approach to scoliosis exercises (SEAS) performed. Reported compliance in the 4.10±1.2 treatment years was 94%, with satisfaction regarding treatment and excellent results at the SRS-22. Two patients (7%) remained above 50° Cobb but six patients (21%) finished between 30° and 35° Cobb and 12 patients (43%) finished between 36° and 40° Cobb. Improvements have been found in 71% of patients and a 5° Cobb progression in one patient. Statistically, we found highly significant reductions of the main (-9.25°), average (-6.6°), thoracic (-7.8°), and lumbar (-15.9°) curves. Statistically significant improvements have been found for the AI and ATR, with a general decrease in plumb line distances. Bracing can be successfully used in patients who do not want to undergo operations for IS with curves ranging between 45° and 60° Cobb, given sufficient clinical expertise to apply good braces and achieve great compliance. Future studies could demonstrate the percentages at which this result can be achieved." }, { "id": "pubmed23n0504_7732", "title": "Three-dimensional action of Chêneau brace on thoracolumbar scoliosis.", "score": 0.00980392156862745, "content": "We treated 18 girls for idiopathic thoracolumbar scoliosis with Chêneau brace.

However until recently no prospective controlled end-result study is presented comparing the results obtained with this soft brace to natural history. The objective was to determine whether the results obtained by the use of the SpineCor are better than natural history during pubertal growth spurt. The method employed prospective comparison of the survival rates of SpineCor treatment vs. natural history with respect to curve progression during pubertal growth spurt. 12 Patients with Cobb angles between 16 and 32 degrees (at average 21 degrees) during pubertal growth spurt are presented as a case series treated with the SpineCor. Survival rate of this sample is described and compared to natural history (SRS brace study 1995). All girls treated in both studies were at risk for being progressive with the first clinical signs of maturation (Tanner 2-3). During the pubertal growth spurt most of the patients (11/12) with SpineCor progressed clinically and radiologically as well (at least 5 degrees). Progression could be stopped changing SpineCor to the Chêneau brace in most of the sample described (7/10). The avarage Cobb angle at the start of treatment with the SpineCor was 21.3 degrees, after an average observation time of 21.5 months 31 degrees. At 24 months of treatment time 33% of the patients with the SpineCor where still under treatment with their original bracing concept, at 72 months follow-up time 8 % of the patients with the SpineCor survived with respect to curvature progression. Survival proportion in the SpineCor sample, though was 0.08, while in the natural history cohort it was 0.34. The SpineCor treatment during pubertal growth spurt seems to lead to a worse outcome than observation only. The use of a simple biomechanical model explains that in the brace the compression forces exceed the lateral forces used for the corrective movement. Therefore SpineCor does not seem to be indicated as a treatment during pubertal growth spurt." }, { "id": "pubmed23n0958_18606", "title": "Effect of the Chêneau Brace in the Natural History of Moderate Adolescent Idiopathic Scoliosis in Girls: Cohort Analysis of a Selected Homogenous Population of 100 Consecutive Skeletally Immature Patients.", "score": 0.009615384615384616, "content": "Α series study. To evaluate the relationships between the effectiveness of brace in reduction of scoliosis angle, axial trunk rotation (ATR), and patients' compliance, in skeletally immature females with moderate adolescent idiopathic scoliosis (AIS), treated with Chêneau brace for a minimum of three years.

From the 100 patients who were initially recruited, 88 patients were included in the final analysis. The average ± SD primary scoliosis angle before brace application was 36.8° ± 9.9°, 32.7° ± 6.3°, and 33.5° ± 11.5° for major thoracic, thoracolumbar, and lumbar curvatures, respectively.
