It is a study of iron deficiency anemia with normal gastroscopy and colonoscopy, having ruled out possible celiac disease. We have yet to see jejunum and ileum, so we will have to perform a capsule endoscopy. In iron deficiency anemia, a digestive cause must always be ruled out.

A 65-year-old woman with a history of joint pain and under treatment with anti-inflammatory drugs is referred for anemia. In the complementary studies she presented red blood cells 3,164,000, Hto. 32%, Hb 11g/dl, MCV 69 fl, Leukocytes 7800, Platelets 370,000, CRP 0.29 mg/dl, Fe 20ng/ml, Ferritin 18 ng/ml, Glucose 105 mg/dl, GOT, GPT, GGT, Alkaline F, total Bilirubin, Cholesterol, Creatinine, Calcium and Phosphorus normal. Negative antitransglutaminase and antigliadin antibodies. Gastroscopy: hiatus hernia of 3 cm, the rest without alterations. Colonoscopy: up to cecum, isolated diverticula in sigma. Intestinal transit without alterations. Ultrasound of the abdomen without alterations. Which of the following examinations do you consider most appropriate to complete the study?

[Malignant peritoneal mesothelioma].

The peritoneal mesothelioma is a rare pathology with unspecific symptoms reason to be a difficult diagnosis. We report a case of a 58 year old man with diabetes mellitus type 2, arterial hypertension and smoking; without precedent of asbestos exposure. The patient presented a one month history characterized by progressive increase of the abdominal volume and sensation of fullness; three weeks later they added breathlessness and hyporexia. The patient was in regular general condition; he was not presenting hepatic stigmas, edema or adenomegalies. The examination of thorax and cardiovascular it was normal. The abdomen distended by ascites, not painful, liver and spleen not examined. Laboratory: Hemoglobin 11,9 gr/dl, WBC 6840/mm3 Bands 1 %, lymphocytes 10 %, platelets 620000/mm3, PT 12 seconds, PTT 34 seconds, glucose 158 mg/dl, BUN 20,5 mg/ dl, creatinine 1,2 mg/dl, proteins 6,1 gr/dl, albumin 2,6 gr/dl. LDH 316 U/l, beta2microglobulin 2,2 mg/l (0.83-1.15 mg/l). HBV and HCV negative. Ca 19.9, CEA, AFP and PSA negative. Hemocultive negative. Ascitic fluid: ADA 20,3 U/l, serum-ascitic albumin gradient (SAAG) 1,1. Leukocytes 2237 cells/mm3, PMN 6 %, lymphocytes 90 %, mesothelial cells 4 %, proteins 4,6 gr/dl, albumin 2,34 gr/dl, glucose 44 mg/dl, LDH 1918 U/l. Gram and cultive: negatives. BAAR and cultive: negative . Cytology: mesothelial cells with changes of type reagent, Block cell for tumour cells: negative. Abdominal US: increased peritoneum and abundant ascitic fluid. Thoracic-abdominal CT: left side pleural effusion, severe ascites with thick epyplon. Upper GI endoscopy: moderate gastritis. Colonoscopy: two small sessile polyps in sigmoid colon. The finds of the laparoscopy were interpreted like carcinomatosis or peritoneal tuberculosis. The report of the peritoneal biopsy was informed as suggestive of undifferentiated carcinoma; the reappraisal with inmunohystochemic (calretinin +,cytokeratin +, vimentin +) indicated malignant peritoneal mesothelioma, type epithelial. The evolution was torpid. The patient was transferred to the Service of Oncology where they initiated chemotherapy with Cysplatin (CDDP) and died 20 days later. The malignant mesothelioma peritoneal is a unfrequent entity, with limited therapeutic options; generally detected late, with a palliative treatment.

Case 244: Systemic Amyloidosis-A Complication of Waldenström Macroglobulinemia.

History A 68-year-old man was admitted to the hospital for work-up because of generalized fatigue, anorexia, chronic diarrhea, and weight loss. Laboratory work-up revealed an erythrocyte sedimentation rate of 58 mm/h (reference range, 3-23 mm/h), a hemoglobin level of 14.1 g/dL (reference range, 13.8-17.5 g/dL), a leukocyte count of 8.1 × 10<sup9</sup/L (reference range, [3.4-9.7] × 10<sup9</sup/L), a platelet count of 223 × 10<sup9</sup/L (reference range, [158-424] × 10<sup9</sup/L), an alkaline phosphatase level of 85 U/L (1.42 μkat/L) (normal level, <142 U/L [2.37 μkat/L]), a serum creatinine level of 93 μmol/L (reference range, 79-125 μmol/L), a serum total protein level of 82 g/L (reference range, 66-81 g/L), a serum albumin level of 39.3 g/L (reference range, 40.2-47.6 g/L), an albumin-to-globulin ratio (a test showing relative amounts of major plasma proteins) of 0.92 (reference range, 0.8-2.0), a urine protein level of 15 mg/dL (normal level, <20 mg/dL), a total serum calcium level of 2.46 mmol/L (reference range, 2.14-2.53 mmol/L), and a carcinoembryonic antigen value of 2.69 μg/L (normal value, <3.4 μg/L). Serology findings were negative for celiac disease. Thyroid function was normal, as were 5-hydroxyindoleacetic acid and chromogranin A levels. Initial radiologic examination included chest radiography and plain abdominal erect radiography. Gastrointestinal endoscopy was performed to rule out inflammatory bowel disease or gastrointestinal neoplasm as a cause of chronic diarrhea. Endoscopic mucosal resection of two polyps from the cardia and duodenal bulb was performed during esophagogastroduodenoscopy, but histologic findings at hematoxylin-eosin staining were normal. Colonoscopy revealed diverticulosis involving the entire colon. Serum immunoelectrophoresis showed a monoclonal band, which was confirmed to be immunoglobulin Mλ at immunofixation. After histologic analysis of the bone marrow biopsy specimen, diagnosis of Waldenström macroglobulinemia was established, and computed tomography (CT) of the thorax, abdomen, and pelvis was requested to depict lymphadenopathy and organomegaly. On the basis of CT findings, two more specimens considered highly sensitive for the CT diagnosis were obtained via minimally invasive biopsy, but the results were negative. Magnetic resonance (MR) imaging was performed a year later to control the progression of CT findings.

Mean Corpuscular Volume -- Evaluation

For microcytic anemia, the presentation will determine the types of studies. If a patient is a menstruating woman with an MCV under 80, a Von Willebrand Factor and/or thyroid panel may be obtained to determine the underlying cause of menorrhagia as well as full menstrual history. On the contrary, a patient with microcytic anemia over the age of 50, is required to obtain a colonoscopy to determine if the iron deficiency originates from a polyp or neoplasm within the colon. Other investigations include urea breath test and an upper endoscopy to test for Helicobacter pylori infection if the patient complains of gastritis type pain. Anemia of chronic disease requires myriad tests if the underlying cause is unknown. Many of these tests include rheumatoid factor, Anti-double stranded DNA antibodies, Anti-neutrophil cytoplastic antibodies , anti-myeloperoxidase antibodies, a urine spot test to determine the renal function with GFR, creatinine, and blood urea nitrogen, HLA-B27 screening, and many more rheumatologic antibodies. Also, screening for malignancies with a CT scan or chest X-ray might be a consideration for the anemia of chronic disease. If lead poisoning is a possibility, a blood lead level is the gold-standard test. However, if other causes of sideroblastic anemia are suspected, a bone marrow biopsy is required. Medical history is very important to uncover the underlying etiology. In this case, the patient may be able to avoid a bone marrow biopsy. If beta-thalassemia is suspected based on history and physical examination, hemoglobin electrophoresis will help determine the amount of AA vs. A2 hemoglobin is present.  Genetic analysis is superior tests for alpha-thalassemia.

When Coke Is Not Hydrating: Cocaine-Induced Acute Interstitial Nephritis.

A 47-year-old African American man was admitted with 4 days of back pain, nausea and vomiting, and low urine output. There was no history of fever, dysuria, frequency, hesitancy, viral symptoms, trauma, rash, or constipation. Despite his past medical history of hypertension, diabetes mellitus, and hyperlipidemia he denied taking any medications for 18 months, including nonsteroidal anti-inflammatory drugs, acetaminophen, or antacids. He denied smoking and alcohol but admitted to cocaine use. No significant FH. Physical examination results were as follows: BP 235/125 mm Hg, heart rate 90 beats/min, temperature 98°F, O2 saturation normal; lungs and heart normal, abdomen soft but bilateral costovertebral angle tenderness. Neurological examination was normal. Laboratory tests yielded the following results: creatinine (Cr) 10.5 mg/dL (1.2 mg/dL in 2010), blood urea nitrogen 63 mg/dL, glucose 151 mg/dL, Ca 9.4 mg/dL, PO4 6.1 mg/dL, Hgb 15 g/dL, white blood cells (WBC) 9100, platelets 167 000, amylase/lipase normal, aspartate aminotransferase/alanine aminotransferase (AST/ALT) normal, bilirubin 1.4 mg/dL, alkaline phosphatase 39 IU/L, creatine phosphokinase 127 µg/L. Hepatic panel, C- and P-ANCA (cytoplasmic- and perinuclear-antineutrophil cytoplasm antibodies, respectively), anti-GBM (anti-glomerular basement membrane), antimyeloperoxidase, antinuclear antibody, and Helicobacter pylori were all negative. C3, C4 normal, urinalysis: 2+ blood, no white blood cells or eosinophils, no casts, no albumin, negative for nitrate/leukocyte esterase and bacteria. Imaging: chest radiograph, abdominal radiograph, computed tomography of the abdomen, electrocardiography, and transthoracic echocardiography were all normal. Course. The patient's urine output declined from 700 to 400 cm(3)/d and the on third day he required hemodialysis with Cr 14 mg/dL. Renal biopsy showed typical findings of interstitial nephritis. 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.

attendant expense. Decision-analysis studies show that serology testing for celiac sprue in patients with IBS-D has an acceptable cost when the prevalence of celiac sprue is >1% and is the dominant strategy when the prevalence is >8%. In patients with concurrent symptoms of dyspepsia, upper GI radiographs or esophagogastroduodenoscopy may be advisable. In patients with postprandial right upper quadrant pain, an ultrasonogram of the gallbladder should be obtained. Laboratory features that argue against IBS include evidence of anemia, elevated sedimentation rate, presence of leukocytes or blood in stool, and stool volume >200–300 mL/d. These findings would necessitate other diagnostic considerations.

Anemia in pregnancy

MCV 80 - 100 fL - Iron deficiency - Infection - Hypothyroidism - Liver disease or alcohol use - Drug-induced - Hemolysis - Vitamin B12 or folate deficiency MCV > 100 fL - Vitamin B12 or folate deficiency - Drug induced - Liver disease or alcohol use - Hypothyroidism - Myelodysplastic Syndromes Pregnancy Pregnant women need almost twice as much iron as women who are not pregnant do. Not getting enough iron during pregnancy raises risk of premature birth or a low-birth-weight baby. Hormonal changes in the pregnant woman result in an increase in circulating blood volume to 100 mL/kg with a total blood volume of approximately 6000–7000 mL. While red cell mass increases by 15–20% during pregnancy, plasma volume increases by 40%. Hemoglobin levels less than 11 g/dL during the first trimester, less than 10.5 g/dL during the second and third trimesters and less than 10 mg/dL in the postpartum period are considered anemic.

[Gastrointestinal bleeding of unknown origin. Experience in 31 cases].

Thirty one patients with GI bleeding of obscure origin, defined as those with normal upper endoscopy and colonoscopy, were studied to know the yield of different diagnostic procedures. Seventeen patients consulted for hematochezia and bleeding less than 10 days of evolution in 71%. Small bowel X ray examination was performed in 14 cases with a diagnostic effectiveness (number of diagnosis/number or examination) of 14%, angiography was performed in 12 cases with an effectiveness 33%, radiolabeled erythrocyte scanning in 12 cases with an effectiveness of 75%, scintigraphy with pertechnetate in 6 cases with an effectiveness of 17% and intraoperatory endoscopy in 2 cases with an effectiveness of 50%. A definitive diagnosis was reached in 8 patients during the first admission and in 6 during the second admission. The principal etiologies were small bowel tumors in 3 cases, cecal ulcers in 2 and ileal diverticula in 2. Ten subjects were subjected to surgical and 2 to endoscopic treatment. Five patients with recurrent bleeding remain without diagnosis. It is concluded that radiolabeled erythrocyte scanning and angiography are effective examinations that should follow upper and lower endoscopies in the diagnosis of a concealed GI bleeding. When a diagnosis is not reached in the first admission, patients should be following with repeated diagnostic procedures.

Prevalence of hematinics deficiency amongst female students and its correction.

Nutritional anemia (NA) is common in India. While iron deficiency (ID) is a well recognized cause of NA, prevalence of deficiencies of other hematinics is not systematically investigated. Seventy students of a junior class of a polytechnic and 202 inmates of girl students home were taken up for study. Students were given a questionnaire to elicit anemia related symptoms. Blood was collected for complete blood count (CBC), serum ferritin, folic acid and vitamin B12. Students of polytechnic received hematinic at bed time during their menstrual periods whereas inmates of students home received hematinic at bed time, 3 days in a week. After 6 months blood tests were repeated in those who completed the treatment. CBC was done on Coulter counter and ferritin, folic acid and vitamin B12 were assayed by chemiluminescence. Students were divided into three groups-(1) Control group with Hb 12.0 g/dl or more and ferritin 15.0 ng/ml or more; (2) ID Group with Hb 12.0 g/dl or more and ferritin less than 15.0 ng/ml; and (3) Iron Deficiency Anemia (IDA) group with Hb less tha 12.0 g/dl and ferritin less than 15.0 ng/ml. Basal parameters of three groups were compared using students t test. Change in parameters with treatment was compared using paired students t test. Median age-16 years (range 10-25). Anemia ( Hb < 12.0 g/dl)-94 (34.6%); MCV < 80 fl-153 (56.3%); MCH < 27 pg-167 (61.4%); Ferritin < 15.0 ng/ml-161 (59.2%); Folic acid < 3.5 ng/ml-34 (12.5%); Vitamin B12 < 258 pg/ml-133 (48.9%) Pre-therapy: (1) Hb, MCV, MCH and ferritin significantly lower in ID and IDA Groups compared to control group. (2) Hb, MCV, MCH and Ferritin significantly lower in IDA Group as compared to ID Group.  POST-THERAPY: (1) IDA group showed significant increase in Hb, MCV, MCH, ferritin, folic acid and vitamin B12. (2) final Hb (11.26+1.07) and ferritin (7.46+4.81) in IDA Group were subnormal. (3) MCV, MCH, ferritin, folic acid and vitamin B12 increased significantly in ID Group and control group. (1) Nutritional anemia is common amongst asymptomatic young female students. (2) Deficiencies of iron, folic acid and vitamin B12 are common and coexist. (3) 105 mg elemental iron for 3 days in a week for 6 months is not adequate to correct IDA. (4) 105 mg iron for 3 days in a week is enough to correct ID. (5) Non-anemic individuals with ID have iron deficient erythropoiesis. (6) Non-anemic individuals without ID, in this cohort, also had iron deficient eryhtropoiesis.

[Effect of Helicobacter pylori eradication on iron deficiency anemia of unknown origin].

Iron deficiency anemia of unknown origin is a frequent cause of anemia in which etiological diagnosis is often not achieved, despite currently available diagnostic techniques. Recent studies suggest that, in the absence of digestive tract lesions, Helicobacter pylori infection could be the cause of iron deficiency anemia, due to the alterations produced in gastric iron absorption. To evaluate whether H. pylori eradication resolves iron deficiency anemia and removes the need for oral iron administration. We performed an observational descriptive study in patients with iron deficiency anemia refractory to treatment with oral iron administration and with out causes that could explain their anemia. Gastroscopy, ileocolonoscopy, intestinal transit study and/or endoscopic capsule were performed. Female patients also underwent gynecological study. All patients were H. pylori-positive and standard eradication therapy was administered until elimination was achieved. The patients were followed-up for a minimum of 3 months after H. pylori eradication and the need for oral iron intake after eradication was evaluated. Ten patients, aged 53+/-8.2 years, were included. Hemoglobin (Hbg) before treatment was 10.06+/-0.53 mg/dl, mean corpuscular volume (MCV) was 75.43+/-6.02 fl and ferritin was 6.1+/-3.28 ng/ml. Eradication therapy was administered until elimination of H. pylori. The mean time before disappearance of anemia was 4.5 months. Laboratory parameters after treatment were as follows: Hgb 12.86+/-0.75 mg/dl, MCV 85.02+/-4.8 fl and ferritin 28+/-22.19 ng/dl. In the absence of lesions that could explain iron deficiency anemia, this disease can be related to H. pylori infection. Eradication of this infection is closely followed by disappearance of anemia and ferropenia.

The Role of Advanced Practitioners in Optimizing Clinical Management and Support of Patients With Polycythemia Vera.

<bCASE STUDY</b Mr. M, a 65-year-old male, presented to his primary care physician with progressive fatigue, difficulty sleeping, and daily headaches for the past 3 weeks. His headaches were not associated with visual disturbances, cognitive deficits, or nausea/vomiting, and he had no history of migraines. He had a history of hypertension and hyperlipidemia, did not smoke, rarely drank alcohol, and had no recent illnesses or hospitalizations. His previous physical examination and laboratory studies 2 years ago were normal. The current physical examination revealed a plethoric yet well-appearing, well-nourished male in no acute distress. His lungs were clear to auscultation bilaterally without wheezes, rales, or rhonchi. He had a regular heart rate and rhythm without murmur. His abdomen was soft, without tenderness, distension, or palpable hepatosplenomegaly. Examination of the extremities was negative for edema. Distal pulses and sensation in the hands and feet were intact and equal bilaterally. Cranial nerves II to XII were deemed intact, and no gross focal deficits were observed. Complete blood count (CBC) revealed a slightly elevated white blood cell (WBC) count (14.6 × 10<sup9</sup/L [normal range, 3.9-10.7 × 10<sup9</sup/L; Wians, 2015]), erythrocytosis (red blood cell [RBC] count, 6.5 × 1012/L [normal range, 4.2-5.9 × 1012/L; Wians, 2015], hemoglobin, 19 g/dL [normal range, 14-17 g/dL; Wians, 2015], and hematocrit, 54.3% [normal range, 41%-51%; Wians, 2015]), thrombocytosis (platelet count, 500 × 109/L [normal range, 150-350 × 10<sup9</sup/L; Wians, 2015]), and microcytosis (mean cell volume [MCV], 75 fL [80-100 fL; Wians, 2015]), which combined were cause for referral to a hematology/oncology clinic. During his hematology/oncology evaluation, Mr. M described "never feeling rested" and being unable to sleep with uncertain snoring habits. He was experiencing itching during hot showers yet did not have rashes and had not recently introduced a new soap. He had no family history of blood disorders and no personal history of blood clots. The second CBC and laboratory tests confirmed erythrocytosis (RBC count, 6.5 × 1012/L; hemoglobin, 18.9 g/dL; hematocrit, 54%) and microcytosis (MCV, 75 fL). Serum iron (22 μg/dL [normal range, 60-160 μg/dL]) and ferritin (5 ng/mL [normal range, 15-200 ng/mL]) were suggestive of iron deficiency, serum erythropoietin was 8 mU/mL (normal range, 4.0-18.5 mU/mL), and a Janus kinase 2 (JAK2) mutation analysis was positive for JAK2V617F. Platelet count remained 500 × 109/L and WBC count was 10.2 × 10<sup9</sup/L.

hip (retrocecal appendix). In addition, pain with rectal or cervical examinations is also suggestive of pelvic appendicitis.Laboratory FindingsPatients with appendicitis usually have leukocytosis of 10,000 cells/mm3, with a higher leukocytosis associated with gangrenous and perforated appendicitis (∼17,000 cells/mm3). C-reactive pro-tein, bilirubin, Il-6, and procalcitonin have all been sug-gested to help in the diagnosis of appendicitis, specifically in predicting perforated appendicitis.14,15 The authors believe that a white blood cell (WBC) count and a C-reactive protein are two appropriate lab tests to obtain in the initial work up of appendicitis; a pregnancy test is also essential in women of childbearing age. Lastly, a urinalysis can be valuable in ruling out nephrolithiasis or pyelonephritis.ImagingImaging is often utilized to confirm a diagnosis of appendici-tis because a negative operation rate is acceptable in <10% of male patients and <20% of female patients.

Clomifene

In normal men, 50 mg/day clomifene for 8 months has been found to increase testosterone levels by around 870 ng/dL in younger men and by around 490 ng/dL in elderly men. Estradiol levels increased by 62 pg/mL in younger men and by 40 pg/mL in elderly men. These findings suggest that the progonadotropic effects of clomifene are stronger in younger men than in older men. In men with hypogonadism, clomifene has been found to increase testosterone levels by 293 to 362 ng/dL and estradiol levels by 5.5 to 13 pg/mL. In a large clinical study of men with low testosterone levels (<400 ng/dL), 25 mg/day clomifene increased testosterone levels from 309 ng/dL to 642 ng/dL after 3 months of therapy. No significant changes in HDL cholesterol, triglycerides, fasting glucose, or prolactin levels were observed, although total cholesterol levels decreased significantly.

If capsule endoscopy is positive, management is dictated by the finding. If capsule endoscopy is negative, current recommendations suggest patients may either be observed or, if their clinical course mandates (e.g., recurrent bleeding, need for transfusions or hospitalization), undergo further testing. “Deep” enteroscopy (e.g., double-balloon, single-balloon, and spiral enteroscopy) is commonly the next test undertaken in patients with clinically important obscure GIB because it allows the endoscopist to examine, obtain specimens from, and provide therapy to much or all of the small intestine. CT and magnetic resonance enterography also are used to examine the small intestine. Other imaging techniques sometimes used in evaluation of obscure GIB include 99mTc-labeled red blood cell scintigraphy, multidetector CT “angiography,” angiography, and 99mTc-pertechnetate scintigraphy for Meckel’s diverticulum (especially in young patients).

Ginseng-Related Drug-Induced Liver Injury.

Ginseng is commonly used as a medicinal herb for memory and concentration and general well-being. Drug-induced liver injury (DILI) is one of the most challenging disorders and trending events in the United States which are related to body building and weight loss supplements. Currently, herbal and dietary supplementation is the second most common cause of DILI. Here, we report on a 45-year-old healthy Chinese woman who presented with dull intermittent left upper quadrant abdomen pain for a month. Upon thorough history taking, she had been taking ginseng tea and supplementation for her menopausal symptoms for almost 3 months. Physical examination was unremarkable except mild tenderness in left upper quadrant of the abdomen. Liver function test showed aspartate transaminase (AST) 717 U/L, alanine transaminase (ALT) 343 U/L, total bilirubin 5 mg/dL, direct bilirubin 3.3 mg/dL, alkaline phosphatase 182 U/L, with international normalized ratio (INR) 1.2. Prior liver enzymes (6 months earlier) showed AST 21 U/L, ALT 18 U/L, total bilirubin 0.8 mg/dL, direct bilirubin 0.3 mg/dL, alkaline phosphatase 34 U/L, with INR 0.7. Viral serology for acute hepatitis B, C, E, cytomegalovirus, Epstein-Barr virus, and varicella zoster virus was negative. She was immune to hepatitis A. Her antinuclear antibody was positive. Her anti-Smith antibody, anti-smooth muscle antibody, HFE gene mutation, ceruloplasmin, alpha-1 antitrypsin serologies were within normal references. An abdomen sonogram showed fatty infiltration. Liver biopsy showed moderate to severe portal inflammation and marked lobular disarray. Portal and lobular inflammatory infiltrates consisted of a mixture of histiocytes, lymphocytes, plasma cells, eosinophils, and neutrophils with centrilobular necrosis and focal bridging necrosis, and necro-inflammation. After 6 weeks of follow-up, the patient improved physically, and the abdomen pain resolved. Ginseng has been widely used in the Chinese community as medicinal herb for a variety of conditions for decades. However, proper research has never been done regarding its pharmacokinetics, efficacy, and safety issues. In our case report, the idiosyncratic DILI resulted from ingestion of ginseng as herbal supplementation for premenopausal symptoms. Physicians should be aware of and suspect DILI in any patient with acute liver injury, and patients should be reminded that all medications and supplements have a potential to cause DILI.

[Detection of ectopic gastric mucosa in Meckel's diverticulum by means of scintigraphy with 99mTc-pertechnetate in a 24-year old man].

The article presents a case of a 24-year old man with ectopic gastric mucosa in Meckel's diverticulum. Ectopic gastric mucosa may be present in Meckel's diverticulum and may be associated with peptic ulcer disease and lower gastrointestinal (GI) bleeding. Diagnosing ectopic gastric mucosa can largely benefit from 99"Tc-pertechnetate scintigraphy. A 24-year old man underwent Meckel's diverticulum scintigraphy for timely anamnesis of GI bleeding from uncertain source (enterorrhagia, haemorrhagic anaemia). Upper tract and large bowel endoscopy, enteroclysis, ultrasound, CT and radioactive labelled red blood cells scintigraphy resluts were negative. Ectopic gastric mucosa was detected by 99mTc-pertechnetate scintigraphy. The patient underwent surgery and part of the proximal ileum including Meckel's diverticulum with ectopic gastric mucosa detected by histology was resected. Meckel's diverticulum scintigraphy can help detect ectopic gastric mucosa and improve the disease management in a patient with gastrointestinal bleeding.

Klinefelter's syndrome presenting with leg ulcers.

A 54-year-old man of Persian origin presented to our department with a 1-year history of ulcers on the right leg that had been unresponsive to numerous topical treatments, accompanied by lymphedema of the right leg. Medical history included hypergonadotropic hypogonadism, which had not been further investigated. He was treated for 20 years with testosterone IM once monthly, which he stopped a year before the current hospitalization for unclear reasons. The patient reported no congenital lymphedema. Physical examination revealed two deep skin ulcers (Figure 1) on the right leg measuring 10 cm in diameter with raised irregular inflammatory borders and a boggy, necrotic base discharging a purulent hemorrhagic exudate. Bilateral leg pitting edema and right lymphangitis with lymphadenitis were noted. He had low head hair implantment, sparse hair on the body and head, hyperpigmentation on both legs, onychodystrophia of the toenails (mainly the large toe and less prominent on the other toes), which was atrophic lichen-planus-like in appearance and needed no trimming (Figure 2), normal hand nails, oral thrush, and angular cheilitis. Other physical findings were gynecomastia, pectus excavatum, small and firm testicles, long extremities, asymmetrical goiter, systolic murmur 2/6 in left sternal border, and slow and inappropriate behavior. The patient's temperature on admission was 39 degrees C. Blood cultures were negative for bacterial growth. Results of laboratory investigations included hemoglobin (11.2 g/dL), hematocrit (26.8%), normal mean corpuscular volume and mean corpuscular hemoglobin volume, and red blood cell distribution width (16%). Blood smear showed spherocytes, slight hypochromia, anisocytosis, macrocytosis, and microcytosis. Blood chemistry values were taken for iron (4 micro g/dL [normal range 40-150 micro g/dL]), transferrin (193 mg/dL [normal range 220-400 mg/dL]), ferritin (1128 ng/mL [normal range 14-160 ng/mL]), transferrin saturation (1.5% [normal range 20%-55%]), serum folate (within normal limits), and vitamin B12 (within normal limits). Direct Coombs' test equaled positive 2 + IgG. All these values indicated anemia of chronic diseases combined with hemolytic anemia. Further blood work-up tested antinuclear antibody (positive <1:80 homogeneous pattern), rheumatoid factors (143 IU/mL [positive >8.5 IU/mL]), C-reactive protein (286 mg/L [normal range 0-5 mg/L]), anticardiolipin IgM antibody (9.0 monophosphoryl lipid U/mL [normal range 0-7.00 MPL U/mL]) and antithrombin III activity (135% [normal range 74%-114%]). Results of other blood tests were within normal limits or negative, including lupus anticoagulant, beta2 glycoprotein, anticardiolipin IgG Ab, anti-ss DNA Ab, C3, C4, anti-RO, anti-LA, anti-SC-70, anti-SM Ab, P-ANCA, C-ANCA, TSH, FT4, anti-T microsomal, antithyroglobulin, protein C activity, protein S free, cryoglobulins, serum immunoelectrophoresis, VDRL, hepatitis C antibodies, hepatitis B antigen, and human immunodeficiency virus. Endocrinological work-up examined luteinizing hormone (22.9 mIU/mL [normal range for adult men 0.8-6 mIU/mL]), follicle stimulating hormone (49.7 mIU/mL [normal range for adult men 1-11 mIU/mL]), testosterone (0.24 ng/mL [normal range for adult men 2.5-8.0 ng/mL]), bioavailable testosterone (0.02 ng/mL [normal range for adult men >0.6 ng/mL]), and percent bioavailable test (8.1% [normal value >20%]). These results indicate hypergonadotropic hypogonadism. Plasminogen activator inhibitor 1 was 6 U (normal value 5-20 U/mL). Karyotyping performed by G-banding technique revealed a 47 XXY karyotype, which is diagnostic of Klinefelter's syndrome. Doppler ultrasound of the leg ulcers disclosed partial thrombus in the distal right femoral vein. X-rays and bone scan displayed osteomyelitis along the right tibia. Histological examination of a 4-mm punch biopsy from the ulcer border revealed hyperkeratosis, acanthosis, hypergranulosis, and mixed inflammatory infiltrate containing eosinophils compatible with chronic ulcer. Multiple vessels were seen, compatible with a healing process. Direct immunofluorescence of the biopsy revealed granular IgM in the dermo-epidermal junction. Indirect immunofluorescence was negative. Thyroid function tests showed normal thyroid stimulating hormone and free throxine4. Multinodular goiter was seen on thyroid scan and ultrasound. Thyroid fine needle aspiration was compatible with multinodular goiter (normal follicular cells, free colloid, macrophages with pigment). IV treatment with amoxicillin-clavulanic acid 1 g t.i.d. was administered for 2 weeks, with a decrease in temperature and normalization of the leukocyte level. Oral antibiotic treatment with amoxicillin-clavulanic acid was continued for 10 more days, followed by 25 days of ciprofloxacin for the osteomyelitis. Local treatment included saline soakings followed by application of Promogran (Johnson & Johnson, New Brunswick, NJ) and Kaltostat (ConvaTec Ltd., a Bristol-Myers Squibb Company, New York, NY) with slight improvement. At the same time, the patient was treated with warfarin sodium due to deep vein thrombosis under international normalized ratio 2-3. The patient was treated with IM testosterone once monthly for 1 year, which resulted in a reduction in the diameter and depth of the leg ulcers (Figure 3). Blood tests were not performed for follow-up of the immune state.

Laboratory, Endoscopic, and Radiographic Features Active disease can be associated with a rise in acute-phase reactants (C-reactive protein [CRP]), platelet count, and erythrocyte sedimentation rate (ESR), and a decrease in hemoglobin. Fecal lactoferrin is a highly sensitive and specific marker for detecting intestinal inflammation. Fecal calprotectin levels correlate well with histologic inflammation, predict relapses, and detect pouchitis. Both fecal lactoferrin and calprotectin are becoming an integral part of IBD management and are used frequently to rule out active inflammation versus symptoms of irritable bowel or bacterial overgrowth. In severely ill patients, the serum albumin level will fall rather quickly. Leukocytosis may be present but is not a specific indicator of disease activity. Proctitis or proctosigmoiditis rarely causes a rise in CRP. Diagnosis relies on the patient’s history; clinical symptoms; negative stool examination for bacteria, C. difficile toxin, and ova

Cases from the Osler Medical Service at Johns Hopkins University.

A 37-year-old woman presented with increasing abdominal pain and jaundice. Six weeks before admission, she developed persistent diarrhea and jaundice of the skin. She also bruised easily, and her gums bled. In the subsequent weeks, her appetite decreased, she was fatigued, and she had nausea, vomiting, and abdominal distension. She had a history of drinking 1 quart of vodka every day for 20 years, with brief periods of abstinence; she stopped consuming alcohol 11 days before admission because it no longer provided symptomatic relief. Her past medical history was also notable for depression, including a suicide attempt 4 years earlier. She did not smoke, use illicit drugs, or have unprotected sexual intercourse. She had received no blood transfusions and had not traveled recently. She took no medications, except for occasional ibuprofen. On physical examination, she was thin and deeply jaundiced, and she trembled and responded slowly to questions. She was afebrile but tachypneic, and she had orthostatic hypotension. Her HEENT examination was notable for scleral and sublingual icterus, as well as crusted blood on her gums and teeth. The jugular veins were flat. The cardiac examination revealed tachycardia (heart rate, 103 beats per minute) without murmurs, rubs, or gallops. The abdomen was nontender and protuberant, with hypoactive bowel sounds; the spleen was not palpable, and there was no fluid wave or caput medusae. The liver percussed to 18 cm, with a smooth edge extending 10 cm below the costal margin. She had cutaneous telangiectases on her chest and bilateral palmar erythema. There was no peripheral edema. The neurologic examination was notable for asterixis. Her stool was guaiac positive. Laboratory studies revealed the following values: hematocrit, 21.2%; white blood cells, 17,310/mm(3); ammonia, 42 micromol/L; serum creatinine, 3.9 mg/dL; serum urea nitrogen, 70 mg/dL; albumin, 2.1 g/dL; total bilirubin, 26.8 mg/dL; alanine aminotransferase, 14 U/L; aspartate aminotransferase, 77 U/L; alkaline phosphatase, 138 U/L; prothrombin time, 103 seconds (international normalized ratio, 10.6); and urinary sodium, <5 mg/dL. Urinalysis revealed an elevated specific gravity and numerous muddy granular casts. Hepatitis A, B, and C serologies were negative. On abdominal ultrasound examination, there was no ascites, and the liver was echogenic. The portal and hepatic veins were patent, and the hepatic arteries were normal. The spleen measured 14 cm. What is the diagnosis?

Analysis of clinical characteristics of 2243 with positive anti-gastric parietal cell antibody.

To facilitate the early detection of chronic diseases, we analyzed the clinical characteristics of anti-gastric parietal cell antibody (PCA)-positive population, revealed the early characteristics of the population. According to the retrospective analysis, current situation investigation and comparative analysis of the clinical characteristics and medical history of the subjects, the comparison between the groups was performed. (a) The positive rate of PCA detection in department of gastroenterology in our hospital was 35.80%. Among the individuals who underwent PCA, esophagogastroduodenoscopy (EGD) and pathological examination at the same time, 33.59% of the patients with PCA positive were diagnosed as atrophic gastritis by gastroscopy, which was much higher than 9.09% of the patients with PCA negative. (b) The incidence of gastroesophageal reflux, hypertension, ischemic heart disease (IHD) and cerebral ischemia in PCA-positive population were 65.45%, 81.63%, 15.43%, and 31.61%, respectively, which were significantly higher than those in the control group. (c) The incidence rates of decreased red blood cells (RBC) and increased homocysteine (HCY) in laboratory-related tests were 38.30% and 69.15%, respectively, which were much higher than those in control group. PCA has predictive value for a variety of chronic diseases and timely detection is of great significance.

Case 294.

History A 50-year-old woman presented to the emergency department of our hospital with a 2-day history of lower limb pain associated with unusual asthenia and diffuse arthralgia over the past 3 weeks. She was a native of Guinea and had lived in France for most of her life, working as a personal care assistant. Her only medical history of note was an occurrence of fetal death at 12 weeks gestation when she was 35 years old. She had bilateral lower limb swelling, without changes in skin temperature or color. All proximal and distal arterial pulses were felt. General physical examination findings were otherwise unremarkable. Her laboratory tests showed a decreased hemoglobin concentration of 8.9 g/dL (normal range, 12-16 g/dL), a decreased platelet count of 45 × 10<sup9</sup/L (normal range, 150-400 × 10<sup9</sup/L), a C-reactive protein level of 158 mg/L (normal range, <5 mg/L) and a d-dimer level of 2000 mg/L (normal range, <500 mg/L). Compression US of the lower limbs revealed bilateral calf vein thrombosis involving the fibular and posterior tibial veins. Curative anticoagulation using low-molecular-weight heparin (enoxaparin, subcutaneous injection of 100 units per kilogram of body weight twice a day) was started. The day after the start of anticoagulation therapy, the patient reported dyspnea and acute chest and abdominal pain. Her vital signs were assessed, and she had elevated blood pressure and increased heart rate and respiratory rate, but she remained afebrile. Her cardiac auscultation was unremarkable, besides tachycardia. Skin examination revealed small areas of necrosis on the fingertips of her right hand. Laboratory studies were repeated and showed an increase in serum creatinine level from a baseline value of 0.49 mg/dL to a new value of 1.01 mg/dL (normal range, 0.6-1.1 mg/dL), an apparition of low-grade proteinuria of 0.43 g per day (normal range, <0.3 g/day), and a high serum troponin level of 1066 ng/L (normal range, <14 ng/L), whereas electrocardiography showed no ST segment modification and echocardiography revealed a moderately altered left ventricular ejection fraction (45%). There was no coronary occlusion seen at emergency coronarography. Contrast-enhanced CT of the chest, abdomen, and pelvis was performed (Figs 1, 2) together with cardiac MRI (Figs 3, 4).

[Radioimmunoscintigraphy with monoclonal antibodies in recurrences and metastases of colorectal tumors].

An experimental follow-up plan based on immunoscintigraphy was evaluated in 48 patients, who had undergone resection for colorectal cancer. The results were compared with those concerning other 317 patients submitted to a traditional follow-up (physical examination, blood analysis, endoscopy, ultrasonography, CT scan, barium enema, etc.). Immunoscintigraphy was performed with Iodine 131--or Indium 111--labeled anti-CEA and-19.9 monoclonal antibody, using a gamma-detecting probe (GDP) enabling to perform radioimmunodetections. In addition, radioimmunoguided surgery was performed in two cases of highly suspected recurrence, and radioimmunoguided endoscopy was made in two cases of suspected recurrence after anterior resection for tumor of the rectum. Our gamma-detecting probe differs from the other ones because of its collimator which enables to detect all the radioisotopes that are used for external scanning and because of its particular shape that enables to perform endoscopic radioimmuno detections. The experimental follow-up plan showed cancer recurrence in 27% of the patients vs. 13% of extensive instrumental investigations. Radioimmunoguided surgery appears to provide a higher level of radicality. The same GDP used for intraoperative immunoscintigraphies seems to be effective in the endoscopic study of the pelvis after anterior resection, a clinical occurrence which can hardly be investigated by means of other instrumental diagnostic procedures.

GastroDuoDenal Disease Symptoms and signs of upper GI tract disease include nausea, vomiting, and epigastric pain. Patients usually have an Helicobacter pylori–negative gastritis. The second portion of the duodenum is more commonly involved than the bulb. Fistulas involving the stomach or duodenum arise from the small or large bowel and do not necessarily signify the presence of upper GI tract involvement. Patients with advanced gastroduodenal CD may develop a chronic gastric outlet obstruction. Laboratory, Endoscopic, and Radiographic Features Laboratory abnormalities include elevated ESR and CRP. In more severe disease, findings include hypoalbuminemia, anemia, and leukocytosis.

Relationship between glycosylated hemoglobin and iron deficiency anemia: A common but overlooked problem.

Both diabetes mellitus (DM) and iron deficiency anemia (IDA) are prevalent in every area of the world, and so, the possibility of these two diseases co-existing is also very high. It is our belief that clinical results of any correlation between iron status of the body and glycosylated haemoglobin (HbA1c) would be beneficial to many patients, therefore in this study, the effect of IDA on HbA1c was investigated. A total of 146 patients with DM and IDA were evaluated prospectively. While the patients were administered 270 mg/day of ferrous sulphate (80 mg elemental iron) orally for three months for the treatment of IDA, no interventions were made for the treatment of DM. Patient levels of hemoglobin (Hb), hematocrit, red blood cells (RBC), mean corpuscular volume (MCV), platelet, white blood cells (WBC), serum iron, serum iron binding capacity (SIBC), ferritin, fasting plasma glucose (FPG), HbA1c, body mass index (BMI), C-reactive protein (CRP) values were measured at baseline and at the third month of treatment with iron, and were compared. The median age of our patients was 45 (40-50) and median duration of diabetes was 3 years (1,75-5). While the baseline median Hb was 10.4 (mg/dL) (9.5-11.1), MCV was 74 (fL) (70.8-77), ferritin was 4 (ug/L) (3-6) at three months, Hb was measured at 12.6 (mg/dL) (12.1-13.2), MCV was measured at 82 (fL) (80-86), ferritin was measured at 15 (ug/L) (9-21.2) and was significantly higher compared to baseline values (p < 0.001). The baseline median HBA1c of patients was 7.09 ± 0.51 (%) and three month HBA1c was 6.69 ± 0.53 (%), which was significantly lower than when comparing baseline values with values at third month (p < 0.001). Baseline and three month values for FPG were 118 (mg/dL) (108-132) and 116 (mg/dL) (106-125) respectively, and there was no significant difference (p:0.07). A 2.2 mg/dL (1.5-3.5) increase in median Hb level accompanied a 0.4 % (0.2-0.6) decrease in median HbA1c levels (Spearman rho = -0.362; p < 0.001). Our study has shown conclusivly that IDA is related to increased HbA1c concentrations and HbA1c decreases significantly following treatment with iron. IDA should be considered before making any decisions regarding diagnosis or treatment according to HbA1c.

[A case of hemobilia developing after radiofrequency ablation (RFA) for hepatocellular carcinoma].

We report a case of hemobilia developing after RFA for hepatocellular carcinoma. A 75-year-old woman with hepatitis C was diagnosed as hepatocellular carcinoma (d=15 mm) located in subsegment 7. Laboratory data on admission are AFP 37.3 ng/mL, PIVKA-II 20 mAU/mL, GOT/GPT 84/52 IU/L, T-Bil 1.1 mg/dL, Alb 3.8 g/dL, Plt 8.9x104/microL, and PT 11.8 seconds (INR 1.28) "Child classification A". Under general anesthesia, percutaneous RFA (Cool-tip radionics 10 minutes) was performed. Tumor appeared to be well treated, but on day 5 after the procedure, the patient had sudden upper abdominal pain, followed by the elevation of total bilirubin conc. (3.3 mg/dL) and decrease of Hb. Abdominal ultrasonography showed a debris-like shadow in the gall bladder. Hemobilia was confirmed because endoscopic examination revealed blood contaminated bile from the papilla Vater. Since spontaneous thrombolysis is known to occur in the bile, the patient was only followed by MRI. Symptoms were subsided in a week without any treatment. Obstructive jaundice due to hemobilia is a rare complication of RFA, and may be followed without any treatment.

[Endoscopic diagnosis of colonic tuberculosis].

A 67-year-old woman had developed weakness, fatigue and a 10 kg weight loss over the past year. On examination a cylindrical mass was palpated in the right middle abdominal cavity. Erythrocyte sedimentation rate was increased to 87/126 mm, there was an hypochromic anaemia (haemoglobin 9.1 mg/dl) and an hypoalbuminaemia (32 g/l) with an increase in alpha 2-globulins (9.4 g/l), Cholinesterase activity was decreased to 588 U/l. X-ray film of the abdomen revealed a calcified mesenteric lymph-node and coloscopy demonstrated polypoid tumorous changes with ulcerations, extending from the pole of the caecum to the right flexure. Histological examination showed epithelioid-cell granulomas with Langhans giant cells. Culture grew Mycobacterium tuberculosis, confirming the diagnosis of intestinal tuberculosis. She was treated with oral doses of isoniazid (300 mg daily), rifampicin (600 mg daily) and pyrazinamide (2 g daily) for 2 months, followed by isoniazid and rifampicin for a further 4 months. After this the laboratory tests were within normal limits and urine as well as stool samples contained no acid-fast bacilli. As the patient felt so well she declined another coloscopy.
