ANESTESIOLOGÍA, CUIDADOS CRÍTICOS Y URGENCIAS

[Neumatosis quística intestinal: reporte de un caso].

La neumatosis quística intestinal es una condición infrecuente, caracterizada por la formación de quistes de contenido gaseoso debajo de la mucosa y la serosa intestinales. Mujer de 84 años, con antecedente de artritis reumatoide en tratamiento inmunosupresor, intervenida hace 2 años por neumoperitoneo, con diagnóstico de diverticulosis yeyunal y enfisema mesentérico, acude con cuadro de dolor abdominal difuso de 2 días de evolución, sin otra sintomatología. En la radiografía de abdomen se observa neumoperitoneo con elevación del hemidiafragma derecho y distensión de asas del intestino delgado. Ante la sospecha de perforación de víscera hueca se decide intervención quirúrgica, en la cual se diagnostica a la paciente de neumatosis quística intestinal. La neumatosis quística intestinal es de causa desconocida, aunque en un elevado porcentaje de pacientes se ha visto asociada a enfermedades pulmonares obstructivas, enfermedades del tejido conectivo, inmunosupresión o enfermedades gastrointestinales. Se localiza más frecuentemente en el colon y el intestino delgado. Se diagnostica principalmente mediante pruebas de imagen (radiografía o tomografía computarizada). El tratamiento es conservador, realizándose intervención quirúrgica si existe sospecha de necrosis intestinal. Es difícil el diagnóstico diferencial con un neumoperitoneo por perforación de víscera hueca. Pneumatosis cystoides intestinalis is an infrequent condition, characterized by the formation of gaseous content cysts under the mucosa and intestinal serous. 84-year-old woman, with a history of rheumatoid arthritis under immunosuppressive treatment, operated 2 years ago by pneumoperitoneum, where she was diagnosed of jejunal diverticulosis and mesenteric emphysema, with diffuse abdominal pain of 2 days of evolution, without other symptoms. In abdominal radiography: pneumoperitoneum with elevation of right hemidiaphragm and distention of small intestine. Given the suspicion of perforation of the intestinal wall, surgical intervention was decided, in which the patient was diagnosed with pneumatosis cystoides intestinalis. Pneumatosis cystoides intestinalis has an unknown etiology, although in a high percentage of patients it has been associated with obstructive pulmonary pathologies, connective tissue diseases, immunosuppression or gastrointestinal diseases. It is located more frequently in the colon and small intestine. It is diagnosed mainly through imaging tests (radiography or computed tomography). The treatment is conservative, performing surgical intervention if there is suspicion of intestinal necrosis; being difficult the differential diagnosis with a pneumoperitoneum by perforation of hollow viscera..

[Hemodynamic impact of thrombolytic therapy in acute pulmonary thromboembolism].

To evaluate pre and post-hemodynamic changes after thrombolytic therapy in patients with acute pulmonary embolism with multiple pulmonary segments compromised. Nine patients, 5 females, aged between 27 and 83 (mean 62 +/- 16) years, with the onset of symptoms preceding 7 days, were submitted to thrombolytic therapy, administered after baseline perfusion-ventilation lung scan, echodopplercardiography (ECO) and hemodynamic measurements with a Swan-Ganz thermodilution catheter. The same procedures were done after the thrombolytic infusion. Streptokinase (SK) was used in 7 (78%) cases and recombinant human tissue-type plasminogen activator (rt-PA, alteplase) in 2 with the following doses: SK-250,000 i.u. infusion over 30 min, then 100,000 i.v/h over 24 to 72 h and rt-PA-20 mg in bolus infusion, then 80 mg over 6 h. Thrombolytic was infused in pulmonary artery trunk in 8 (88%) cases and a peripheral vein in 1 (12%) case, until mean pulmonary artery pressure (PAP) reached 20 mmHg. All patients received i.v. heparin and oral anticoagulation after thrombolytic therapy. A significant (p < 0.05) decrease in right atrial pressure (12 +/- 3 vs 8 +/- 2 mmHg), PAP (32 +/- 5 vs 19 +/- 2 mmHg), pulmonary vascular resistance (397 +/- 125 vs 87 +/- 24 dyne.s/cm5) and increase in cardiac output (3.4 +/- 0.5 vs 5.5 +/- 1.0 l/min) and stroke volume (30 +/- 5 vs 57 +/- 10 ml/beat) were observed after thrombolytic infusion. Two patients died as a result of pulmonary infection unrelated to the embolic event or thrombolysis. Minor bleeding complications occurred in two cases and major in one patient with orthopedic prosthesis. Thrombolytic therapy exert desirable effects on hemodynamic abnormalities, achieving lungs scan and ECO improvement in patients with acute pulmonary embolism.

[Ultrasonografía pulmonar en COVID-19: serie de casos].

Objetivo: Describir los hallazgos ultrasonográficos pulmonares en una serie de casos de pacientes con COVID-19. Método: Se incluyeron 10 pacientes con diagnóstico de COVID-19 confirmado por reacción en cadena de la polimerasa. Se realizó ultrasonido pulmonar de dos dimensiones y de 12 cuadrantes a cada enfermo. Resultados: Los patrones identificados fueron alteraciones de la línea pleural por disrupción/desnivel (100%), engrosamiento pleural (100%), consolidación subpleural (90%) y derrame pleural laminar (80%), patrón B1 (60%), patrón B2 (40%) y consolidación (20%), lo que se correlaciona con los hallazgos de autopsias reportados en la literatura, caracterizados por infiltrado intersticial, colapso alveolar y condensación pulmonar. Conclusiones: El ultrasonido pulmonar brinda información sobre el estado de los enfermos con COVID-19, que permite modificar el tratamiento empleado, impactando en los resultados clínicos y optimizando el uso de los recursos disponibles. Los hallazgos de este estudio descriptivo coinciden con los descritos en todo el mundo, concluyendo que la mayoría de los pacientes tendrán algún hallazgo pleuropulmonar patológico en el momento de su evaluación inicial, lo que muestra que la ultrasonografía es un estudio de utilidad en la evaluación y el seguimiento de los pacientes con COVID-19.

[Bolus thrombolysis in pulmonary embolism. Review of experimental and clinical data].

Although heparin is the primary drug used to treat pulmonary embolism, its limits include poor prevention of recurrence, and slow and delayed normalization of hemodynamic parameters. Over the past decades, thrombolysis has proved to be the most rapid and effective therapy to normalize hemodynamic parameters and angiographic and scintigraphic indexes of obstruction. Studies conducted up to the present have not, however, demonstrated a significant advantage over heparin with respect to mortality. Moreover, thrombolytic drugs carry a greater risk of hemorrhage than heparin. Various experimental studies have demonstrated that the short-term administration of recombinant tissue plasminogen activator (rt-PA) is more effective and decreases risk of hemorrhage. To our knowledge, only a few uncontrolled clinical studies on bolus thrombolysis with urokinase have been done. Studies comparing a 0.6 mg/Kg bolus of intravenous rt-PA versus the infusion of 100 mg over 2 hours have given conflicting results. Of these, some have demonstrated that bolus administration is safer and more effective while others have provided nearly overlapping results regarding safety and the reduction of pulmonary resistances. One study reports higher mortality in a group receiving 0.6 mg/Kg bolus rt-PA. Until these questions are clarified, administration of thrombolytics in the following doses is advised: streptokinase bolus 250,000 U over 30 min + 100,000 U/hour for 24 hours; urokinase bolus 4400 U/Kg for 10 min + 4400 U/Kg/hour for 12-24 hours; rt-PA 100 mg for 2 hours.

Dolor torácico y shock secundarios a perforación espontánea de esófago: síndrome de Boerhaave.

La perforación esofágica es la más letal de todas las perforaciones del aparato digestivo. Se presenta el caso de un varón de 65 años que acude a urgencias por un cuadro clínico de dolor torácico, vómitos e hipotensión. Se le realizó tomografía computarizada por sospecha de síndrome aórtico agudo, con hallazgos sugerentes de perforación esofágica. El síndrome de Boerhaave consiste en la rotura longitudinal del esófago sobre una pared macroscópicamente sana. Su tratamiento definitivo se realiza con cirugía durante las primeras 24 horas. El síndrome de Boerhaave debe considerarse como complicación posible en los pacientes con dolor epigástrico y vómitos, ya que es una emergencia quirúrgica con alta morbimortalidad. Esophageal perforation is the most lethal of all perforations of the digestive system. 65-year-old male who goes to the emergency department due to clinical symptoms of chest pain, vomiting and hypotension, who underwent CT scan for suspected acute aortic syndrome, with suggestive findings of esophageal perforation. Boerhaave syndrome consists of the longitudinal rupture of the esophagus on a macroscopically healthy wall. Its definitive treatment is performed with surgery during the first 24 hours. Boerhaave syndrome should be considered as a possible complication in patients with epigastric pain and vomiting, as it is a surgical emergency with high morbidity and mortality.

[Pulmonary embolism. A propos of a case treated with APSAC].

One describes the clinical case of a patient suffering from massive pulmonary embolism under a state of shock who was successfully treated with APSAC 30 units in one single bolus. Thrombolytic agents provoke a rapid destruction of thrombi which lead to a very important and fast hemodynamic improvement. These agents have a great improving action, compared to heparin, in the alterations of pulmonary diffusion provoked by embolism. Most of the times, they also avoid surgery and the appearance of cor pulmonale. APSAC seems to be effective and secure.

Self-Expanding Metal Stents Do Not Adversely Affect Long-term Outcomes in Acute Malignant Large-Bowel Obstruction: A Retrospective Analysis.

Self-expanding metal stents as a bridge to surgery in acute malignant large-bowel obstruction has gained popularity. However, long-term oncologic outcomes have not been well established. To investigate long-term oncologic outcomes of patients undergoing curative resection after the placement of a colonic stent compared with emergency surgery for acute malignant large-bowel obstruction. This is a retrospective study. All patients presenting at 3 tertiary care centers between April 2002 and December 2012 with a diagnosis of complete malignant large-bowel obstruction were reviewed. Patients with disease distal to the hepatic flexure were selected for analysis. One hundred twenty-two patients who underwent either emergency surgery or placement of a colonic stent with curative intent were included. Patients receiving emergency surgery within 24 hours of presenting with obstructive symptoms, including those with failed stents, were included in the emergency surgery group. All patients with clinically successful stent deployment before surgery were included in the stent group. Overall survival and disease-free survival were calculated using the Kaplan-Meier method. Sixty-four patients underwent emergency surgery, and 58 patients underwent placement of a self-expanding metal stent. Groups were similar in terms of sex, tumor stage and grade, and Charlson and Charlson-Age Comorbidity Index scores. Patients in the surgery group were older than patients in the stent group. There were no differences in the number of lymph nodes harvested, positive nodes, rates of vascular and perineural invasion, or utilization of chemotherapy. Thirty-day mortality after resection was similar between groups (7.41% vs 4.41%; p > 0.05). Patients who underwent colonic stenting as a bridge to surgery had similar 10-year overall survival (40.5% vs 32.7%; p = 0.13) and 10-year disease-free survival (40.2% vs 33.8%; p = 0.26) compared with those who underwent emergency surgery. Similar results were seen on intention-to-treat analysis. This was a small retrospective study. Stent insertion followed by oncologic resection is associated with similar overall survival and disease-free survival compared with emergency resection. Stent insertion as a bridge to surgery should be considered in patients presenting with malignant colorectal obstruction.

Los stents metálicos autoexpandibles como puente a una cirugía en la obstrucción maligna aguda del colon han ganado popularidad. Sin embargo, no se han establecido bien los resultados oncológicos a largo plazo. Investigar los resultados oncológicos a largo plazo de los pacientes sometidos a resección curativa después de la colocación de un stent colónico en comparación con la cirugía de urgencia para la obstrucción maligna aguda del colon. Estudio retrospectivo. Entre abril de 2002 y diciembre de 2012, se revisaron todos los pacientes que acudieron a tres centros de tercer nivel con un diagnóstico de obstrucción maligna completa del colon. Se seleccionaron para el análisis los pacientes con enfermedad distal al ángulo hepático. Se incluyeron 122 pacientes que fueron operados de urgencia o a una colocación de un stent colónico con intención curativa. Los pacientes que se sometieron a cirugía de urgencia dentro de las 24 horas posteriores a la presentación de síntomas obstructivos; se incluyeron aquellos con stents fallidos en el grupo de cirugía de urgencia. Todos los pacientes con colocación clínicamente exitosa del stent antes de la cirugía se incluyeron en el grupo de stent. La sobrevida global y la sobrevida libre de enfermedad se calcularon mediante el método de Kaplan-Meier. Sesenta y cuatro pacientes fueron llevados a cirugía urgente y en 58 pacientes se colocó de un stent metálico autoexpandible. Los grupos fueron similares en relación a sexo, estadio y grado del tumor, puntuación de comorbilidad de Charlson y Charlson-Age. Los pacientes del grupo de cirugía eran mayores que los del grupo de stents. No hubo diferencias en el número de ganglios linfáticos recolectados, ganglios positivos, tasas de invasión vascular y perineural o utilización de quimioterapia. La mortalidad a los 30 días después de la resección fue similar entre los grupos (7,41% frente a 4,41%; p> 0,05). Los pacientes que se sometieron a la colocación de un stent colónico como puente a la cirugía tuvieron una sobrevida general a diez años similar (40,5% vs 32,7%; p = 0,13) y una sobrevida libre de enfermedad a diez años (40,2% vs 33,8%, respectivamente; p = 0,26) en comparación a los operados de urgencia. Se observaron resultados similares en el análisis por intención de tratamiento. Estudio retrospectivo reducido. La utilización de un stent y posteriormente la resección oncológica se asocia a una sobrevida general y una sobrevida libre de enfermedad similar en comparación con la resección de urgencia. La utilización de un stent como puente a la cirugía debe considerarse en pacientes que presentan obstrucción colorrectal maligna. Consulte Video Resumen en http://links.lww.com/DCR/B714.

[Diagnosis and therapeutic follow-up of patients with massive pulmonary emboli by two-dimensional echocardiography].

The aim of the study was to analyse the role of 2D echocardiogram (ECHO) in the diagnosis of massive pulmonary embolism (PE), and in the follow-up after fibrinolytic or surgical treatment. Echocardiographic studies were retrospectively analysed in seven patients, 5 male, mean age 37 +/- 19 years, with massive pulmonary embolism (PE) confirmed by pulmonary angiography. Six of them were submitted to fibrinolytic therapy with IV streptokinase (SK), and one underwent surgery. The diagnosis of PE by ECHO was made by the detection of thrombi in the pulmonary vascular bed. ECHO measurements included the right ventricular diastolic diameter (RVDD), interventricular septal motion (IVS), acceleration time (AcT), and peak pulmonary artery pressure (PAP). The ECHO study diagnosed thrombi in five out of seven patients (71%), mainly if they were present in the right main pulmonary artery (four cases -80%). It was also able to locate one out of five patients with thrombus in the right lobar artery and one out of two patients in the left main pulmonary artery; it was unable to identify six patients with involvement of the left lobar arteries. Four out of five patients with PE, diagnosed by ECHO, were submitted to fibrinolytic therapy, and one underwent surgery. The follow-up study showed dissolution of the thrombus in three of those with SK and in the one with surgical treatment. The initial ECHO study showed five out of 7 patients with increased RVDD, 5/7 patients with abnormal IVS motion, and all of them with decreased AcT (64 +/- 16 ms). The PSP was 64.4 +/- 22.8 mmHg by ECHO, versus 75.4 +/- 24.03 mmHg by angiography (r = 0.78; p = 0.11). There was a reduction of the RVDD (30 +/- 5.02 to 23 +/- 2.2) and an increased of the AcT (50 +/- 10.8 to 106.67 +/- 16) at the serial examination. The ECHO study is an important tool for the diagnosis of PE, informing about pulmonary pressure, presence and position of thrombus, and treatment results.

Longitudinal hemodynamics in acute phase of treatment with labetalol in hypertensive pregnant women to predict need for vasodilatory therapy.

Hypertensive pregnant women who do not respond to treatment with labetalol to control blood pressure (BP), but require vasodilatory therapy, progress rapidly to severe hypertension. This could be delayed by early recognition and individualized treatment. In this study, we sought to create prediction models from data at presentation and at 1 h and 24 h after commencement of treatment to identify patients who will not have a sustained response to labetalol and therefore need vasodilatory therapy. The study population comprised 134 women presenting with hypertension at a UK hospital. Treatment with oral labetalol was administered when BP was > 150/100 mmHg or > 140/90 mmHg with systemic disease. BP and hemodynamic parameters were recorded at presentation and at 1 h and 24 h after commencement of treatment. Labetalol doses were titrated to maintain BP around 135/85 mmHg. Women with unresponsive BP, despite labetalol dose maximization (2400 mg/day), received additional vasodilatory therapy with nifedipine. Binary logistic and longitudinal (mixed-model) data analyses were performed to create prediction models anticipating the likelihood of hypertensive women needing vasodilatory therapy. The prediction models were created from data at presentation and at 1 h and 24 h after treatment, to assess the value of central hemodynamics relative to the predictive power of BP, heart rate and demographic variables at these intervals. Twenty-two percent of our cohort required additional vasodilatory therapy antenatally. These women had higher rates of severe hypertension and delivered smaller babies at earlier gestational ages. The unresponsive women were more likely to be of black ethnicity, had higher BP and peripheral vascular resistance (PVR), and lower heart rate and cardiac output (CO) at presentation. Those who needed vasodilatory therapy showed an initial decrease in BP and PVR, which rebounded at 24 h, whereas BP and PVR in those who responded to labetalol showed a sustained decrease at 1 h and 24 h. Stroke volume and CO did not decrease during the acute phase of treatment in either group. The best model for prediction of the need for vasodilators was provided at 24 h by combining ethnicity and longitudinal BP and heart rate changes. The model achieved a detection rate of 100% for a false-positive rate of 20% and an area under the receiver-operating characteristics curve of 0.97. Maternal demographics and hemodynamic changes in the acute phase of labetalol monotherapy provide a powerful tool to identify hypertensive pregnant patients who are unlikely to have their BP controlled by this therapy and will consequently need additional vasodilatory therapy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd. Las embarazadas hipertensas que no responden al tratamiento con labetalol para el control de la presión arterial (PA), pero que requieren terapia vasodilatadora, evolucionan rápidamente hacia una hipertensión severa. Ésta se puede retrasar mediante un diagnóstico precoz y un tratamiento individual. En este estudio se ha tratado de crear modelos de predicción a partir de datos al inicio del tratamiento y al cabo de 1 hora y de 24 horas después del mismo, para identificar a las pacientes que no mostrarán una respuesta constante al labetalol y que por lo tanto necesitarán terapia vasodilatadora. MÉTODOS: La población de estudio incluyó 134 mujeres con hipertensión en un hospital del Reino Unido. El tratamiento con labetalol por vía oral se administró cuando la PA fue >150/100 mm de Hg o >140/90 mm de Hg con enfermedad multisistémica. Se registró la PA y los parámetros hemodinámicos tanto al inicio como al cabo de 1 h y de 24 h después del inicio del tratamiento. Las dosis de Labetalol se ajustaron para mantener la PA en torno a los 135/85 mm de Hg. Las mujeres cuya PA no produjo respuesta, a pesar de haberles administrado la dosis máxima de labetalol (2400 mg/día), recibieron terapia vasodilatadora adicional con nifedipino. Se realizaron análisis de datos mediante logística binaria y longitudinal (modelo mixto), para crear modelos de predicción con los que pronosticar la probabilidad de la necesidad de terapia vasodilatadora en mujeres hipertensas. Los modelos de predicción se crearon a partir de datos al inicio y al cabo de 1 hora y 24 horas del tratamiento, para evaluar el valor de los parámetros hemodinámicos principales con respecto a la capacidad predictiva de la PA, la frecuencia cardíaca y las variables demográficas en estos intervalos. El 22 % de la cohorte necesitó terapia vasodilatadora adicional antes del parto. Estas mujeres tuvieron tasas más altas de hipertensión grave y neonatos más pequeños en edades gestacionales más tempranas. Las mujeres que no respondieron al tratamiento fueron con más frecuencia de raza negra, tuvieron la PA y la resistencia vascular periférica (RVP) más alta, y la frecuencia cardíaca y el gasto cardíaco (GC) más bajos al inicio del tratamiento. Aquellas que necesitaron terapia vasodilatadora mostraron un descenso inicial de la PA y la RVP, que se recuperó al cabo de 24 h, mientras que la PA y la RVP en las que respondieron al labetalol mostraron una disminución constante al cabo de 1 h y de 24 h. El volumen sistólico y el GC no disminuyeron durante la fase aguda del tratamiento en ninguno de los grupos. El mejor modelo para la predicción de la necesidad de vasodilatadores se obtuvo a las 24 h mediante la combinación de la etnia con los cambios longitudinales de la PA y la frecuencia cardíaca. El modelo alcanzó una tasa de detección del 100% para una tasa de falsos positivos del 20% y un área bajo la curva de características operativas del receptor de 0,97. CONCLUSIÓN: Los datos demográficos maternos y los cambios hemodinámicos en la fase aguda de la monoterapia con labetalol constituyen una herramienta poderosa para identificar a las pacientes embarazadas hipertensas con pocas probabilidades de que se les pueda controlar su PA mediante esta terapia y que por lo tanto necesitarán terapia vasodilatadora adicional. : 、(blood pressure,BP),。。,1 h24 h,。 : 134。BP>150/100 mmHgBP>140/90 mmHg。1 h24 hBP。,BP135/85 mmHg。BP,()。logistic(),。1 h24 h,,BP、。 : 22%。。,BP(peripheral vascular resistance,PVR),(cardiac output,CO)。BPPVR,24 h,1 h24 hBPPVR。CO。24hBP。100%,20%,0.97。 : ,BP。.

[Anticoagulants in the treatment of severe pulmonary embolism. A prospective study].

This prospective study was designed to obtain information on the fate of patients with severe pulmonary embolism who received anticoagulants as first-line treatment, in order to identify those in whom other treatments available might be expected to reduce mortality or sequelae. Thirty-seven patients selected as they showed evidence of acute cor pulmonale entered the study. Seven of them (18.9 p. 100) died in hospital, and these were patients whose age (p = 0.004), degree of pulmonary obstruction (p = 0.008) and serum lactate dehydrogenase level (p = 0.001) were significantly higher than those of the other patients. The mean values of these parameters (64 years, 72 p. 100 and 450 IU/l respectively) made it possible to select patients with a high risk of death. At the end of the follow-up period (25 +/- 12 months) only 2 patients complained of moderate dyspnoea, in contrast with the high incidence (17/18 patients) of paraclinical abnormalities observed 3 months after the initial accident. We conclude that clinical trials comparing other treatments with the one we used would be useful if their objective was to reduce mortality in high risk patients. On the other hand, it seems impossible to demonstrate a functional improvement: we found our treatment satisfactory and its results independent of the abnormalities observed on the 3rd month.

Early Follow-up After Colorectal Surgery Reduces Postdischarge Emergency Department Visits.

Thirty-day readmissions, emergency department visits, and observation stays are common after colorectal surgery (9%-25%, 8%-12%, and 3%-5%), yet it is unknown to what extent planned postdischarge care can decrease the frequency of emergency department visits. This study's aim was to determine whether early follow-up with the surgical team reduces 30-day emergency department visits. This retrospective cohort study used a central data repository of clinical and administrative data for 2013 through 2018. This study was conducted in a large statewide health care system (10 affiliated hospitals, >300 practices). All adult patients undergoing colorectal surgery were included unless they had a length of stay <1 day or died during the index hospitalization. Early (<10 days after discharge) versus late (≥10 days) follow-up at the outpatient surgery clinic, or no outpatient surgery clinic follow-up, was assessed. The primary outcome measured was the time to 30-day postdischarge emergency department visit. Our cohort included 3442 patients undergoing colorectal surgery; 38% of patients had an early clinic visit. Overall, 11% had an emergency department encounter between 11 and 30 days after discharge. Those with early follow-up had decreased emergency department encounters (adjusted HR 0.13; 95% CI, 0.08-0.22). An early clinic visit within 10 days, compared to 14 days, prevented an additional 142 emergency department encounters. Nationwide, this could potentially prevent 8433 unplanned visits each year with an estimated cost savings of $49 million annually. We used retrospective data and were unable to assess for health care utilization outside our health system. Early follow-up within 10 days of adult colorectal surgery is associated with decreased subsequent emergency department encounters. See Video Abstract at http://links.lww.com/DCR/B330. EL SEGUIMIENTO TEMPRANO DESPUÉS DE LA CIRUGÍA COLORRECTAL REDUCE LAS VISITAS AL SERVICIO DE URGENCIAS POSTERIOR AL ALTA: Los readmisión a los treinta días, las visitas al servicio de urgencias y las estancias de observación son comunes después de la cirugía colorrectal, 9-25%, 8-12% y 3-5%, respectivamente. Sin embargo, se desconoce en qué medida la atención planificada posterior al alta puede disminuir la frecuencia de las visitas al servicio de urgencias.Determinar si el seguimiento temprano con el equipo quirúrgico reduce las visitas a 30 días al servicio de urgencias.Este estudio de cohorte retrospectivo utilizó un depósito central de datos clínicos y administrativos para 2013-2018.Gran sistema de salud estatal (10 hospitales afiliados,> 300 consultorios).Se incluyeron todos los pacientes adultos de cirugía colorrectal a menos que tuvieran una estadía <1 día o murieran durante el índice de hospitalización.Temprano (<10 días después del alta) versus tardío (≥10 días) o sin seguimiento en la clínica de cirugía ambulatoria.Tiempo para la visita al servicio de urgencias a 30 días después del alta.Nuestra cohorte incluyó 3.442 pacientes de cirugía colorrectal; El 38% de los pacientes tuvieron una visita temprana a clínica. En total, el 11% tuvo un encuentro con el servicio de urgencias entre 11 y 30 días después de ser dado de alta. Aquellos con seguimiento temprano disminuyeron las visitas al servicio de urgencias (HR 0,13; IC del 95%: 0,08 a 0,22). Además, una visita temprana a la clínica en un plazo de 10 días, en comparación con 14 días, evitó 142 encuentros adicionales en el servicio de urgencias. A nivel nacional, esto podría prevenir 8.433 visitas no planificadas cada año con un ahorro estimado de $ 49 millones anuales.Utilizamos datos retrospectivos y no pudimos evaluar la utilización de la atención médica fuera de nuestro sistema de salud.El seguimiento temprano dentro de los 10 días de la cirugía colorrectal en adultos se asocia con una disminución de los encuentros posteriores en el servicio de urgencias.

[Acute pulmonary thromboembolism with severe hemodynamic compromise. The efficacy of systemic thrombolytic treatment in the coronary unit].

A 79[correction of seventy]-year-old patient, who has been in bed a long time, suffered an episode of sudden dyspnea, tachycardia and tachypnea. An electrocardiogram registered at her admission in the coronary care unit showed a normal rhythm with right axis deviation and S1Q3T3 pattern and ST segment alterations. A ventilation-perfusion lung scanning demonstrated segmental perfusion defects with high probability of pulmonary embolism. She developed a low cardiac output syndrome, which neither responded to the volume expansion nor to the inotropic drugs. The bed-side hemodynamic measurements were a systolic pulmonary pressure of 60 mmHg, with a diastolic pressure of 18 mmHg and capillary wedge pressure of 13 mmHg with high pulmonary resistance. With this evidences, the diagnoses of massive pulmonary embolism was done, thrombolytic treatment was decided on. Two hundred and fifty thousands international units of streptokinase was administered, and then 100.000 UI/hour in 24 hours; after that with intravenous heparin. The low cardiac output syndrome disappeared. The patients recovered her systemic arterial pressure and her diuresis. The electrocardiographic signs vanished and both the pulmonary pressure and resistance decreased. We discussed the importance of intravenous thrombolytic treatment in massive pulmonary embolism. We concluded than this treatment is an useful strategy that not always needs a pulmonary arteriography, and could be used in low complexity centres, successfully in the massive pulmonary thromboembolism with severe hemodynamic damage.

[Prognostic value of transthoracic echocardiography in hemodynamically stable patients with acute symptomatic pulmonary embolism].

To determine the prognostic value of transthoracic echocardiography in hemodynamically stable patients diagnosed with acute symptomatic pulmonary embolism. Hemodynamically stable outpatients diagnosed with acute symptomatic pulmonary embolism at a tertiary university hospital were prospectively included in the study. All patients underwent transthoracic echocardiography within 48 hours of diagnosis. The primary endpoint was all-cause mortality at 1 month. Right ventricular dysfunction was documented by echocardiography in 86 of the 214 patients (40%) in our series. In the first month of follow-up, 7 patients died--4 with positive echocardiographic findings and 3 with negative findings (odds ratio, 2.0; 95% confidence interval, 0.4-9.3; P=.41). For the primary endpoint, the negative predictive value of transthoracic echocardiography was 98%, the positive predictive value was 5%, and the negative likelihood ratio was 0.7. The negative predictive value was 100% and the positive predictive value was 3% when we analyzed death due to pulmonary embolism only. In our setting, transthoracic echocardiography is not useful for prognostic stratification of hemodynamically stable patients with pulmonary embolism.

[Cerebral abscess due to Eikenella corrodens in an immunocompetent pediatric patient].

Introducción: Los abscesos cerebrales son una urgencia neurológica grave con alto riesgo de déficit neurológico permanente. Son patologías raras en la edad pediátrica, con una incidencia anual de 0.5 por 100,000 niños. Se han realizado pocos estudios de abscesos cerebrales de origen odontogénico y la mayoría de los pacientes son adultos con patología dental de base. Eikenella corrodens es un cocobacilo gramnegativo anaerobio facultativo de crecimiento fastidioso, que forma parte de la biota de la cavidad oral, pero es un patógeno frecuente en infecciones de cabeza y cuello, así como en infecciones dentales. Caso clínico: Paciente de sexo masculino de 16 años, previamente sano, que presentó cefalea de 2 meses de evolución acompañada de náuseas y vómitos. Antecedente de extracción del cuarto molar superior derecho 4 meses antes, sin uso de profilaxis antibiótica. La resonancia magnética de cráneo mostró una lesión compatible con absceso cerebral. Se realizó drenaje por punción guiada por estereotaxia, del que se aisló E. corrodens. El paciente completó un tratamiento con ceftriaxona y metronidazol por vía intravenosa durante 4 semanas y ampicilina-sulbactam por vía oral por 2 semanas más. Conclusiones: Los abscesos cerebrales de origen odontogénico causados por E. corrodens en la edad pediátrica son muy raros. Actualmente, el uso de antibióticos profilácticos en procedimientos dentales es controversial, ya que se ha documentado el aumento de la resistencia microbiana por su uso indiscriminado. La optimización de los estudios diagnósticos y el tratamiento multidisciplinario han mejorado el pronóstico de los pacientes con absceso cerebral.

[Diagnosis of pulmonary thromboembolism].

Pulmonary embolism (PE) is an important disease entity in clinical medicine. It consists of obstruction of pulmonary arterial blood flow of a clot embolism from distant sites of the vasculature. Its incidence is variable depending on the source analyzed and most existing data is in hospitalized patients. The clinical presentation is a broad spectrum, from asymptomatic to cardiogenic shock with sudden death due to acute right heart failure. Recently it has been used to D-dimer as a useful laboratory test and a large negative predictive value in the diagnosis of PE. The current classification schemes recommended guided in clinical, laboratory and image. Chest angiotomography is currently the most commonly used diagnostic method for confirmation of pulmonary embolism, but the standard remains arteriography.

18F-FDG PET/MRI for Rectal Cancer TNM Restaging After Preoperative Chemoradiotherapy: Initial Experience.

F-FDG-PET/MRI is a novel hybrid techinque that has been recently introduced in oncological imaging, showing promising results. The aim of this study is to assess the value of whole-body F-FDG-PET/MRI for predicting the pathological stage of locally advanced rectal cancer after preoperative chemoradiotherapy. This was a prospective observational study. The study was conducted at a tertiary care hospital. Thirty-six patients with locally advanced rectal cancer (25 male, median age 68.5 years) were prospectively assessed with PET/MRI and thoracoabdominal CT before and after preoperative chemoradiotherapy. Twenty-seven patients underwent low anterior or abdominoperineal resection. Nine patients with a complete clinical response underwent organ-preserving treatment (8 local excision and 1 watch-and-wait approach) with >1-year follow-up. One radiologist evaluated pelvic MRI and CT. A second radiologist and a nuclear medicine physician jointly assessed PET/MRI. The imaging was compared with histology or follow-up (ypT0 vs T ≥1 and ypN0 vs ypN+ categories). Metastases were confirmed with biopsy or a follow-up CT scan at least at 1 year after preoperative chemoradiotherapy. The sensitivity, specificity, and accuracy values of the imaging techniques were calculated using standard formulas. The accuracy for ypT staging was 89% and 92%, and the accuracy for ypN was 86% and 92% for MRI and PET/MRI. Compared with CT, PET/MRI correctly diagnosed 4 of 5 metastases, but it did not detect a lung metastatic nodule. In 11% of the patients, the PET/MRI changed the treatment strategy. This study is limited by its small sample size. Although the whole-body PET/MRI was more accurate than the pelvic MRI alone for the prediction of tumor and node response to preoperative chemoradiotherapy, the technique performed worse than CT in detecting small lung metastasis.

TOMOGRAFÍA POR EMISIÓN DE POSITRONES DE 18F- FLUORODEOXIGLUCOSA (FDG) / RESONANCIA MAGNÉTICA (TEP/RM) PARA ESTADIFICACIÓN TUMORAL TNM DE CÁNCER DEL RECTO DESPUÉS DE LA QUIMIORRADIOTERAPIA PREOPERATORIA - EXPERIENCIA INICIAL: Evaluar el valor de la tomografía por emisión de positrones de 18F-fluorodeoxiglucosa / resonancia magnética (TEP/RM) para predecir el estadio patológico del cáncer de recto localmente avanzado después de la quimiorradioterapia preoperatoria.Este fue un estudio prospectivo observacional.El estudio se realizó en un hospital de atención terciaria.Treinta y seis pacientes con cáncer rectal localmente avanzado (25 hombres, edad media de 68.5 años) fueron evaluados prospectivamente con TEP/RM y tomografía computarizada (TC) toraco-abdominal antes y después de la quimiorradioterapia preoperatoria. Veintisiete pacientes se sometieron a resección anterior baja o abdominoperineal. Nueve pacientes con una respuesta clínica completa se sometieron a un tratamiento de preservación de órganos (8 escisión local y 1 un enfoque de observar y esperar) con un seguimiento de> 1 año.Un radiólogo evaluó la RM pélvica y la TC. Un segundo radiólogo y un médico de medicina nuclear evaluaron conjuntamente TEP / RM. La imagen se comparó con la histología o el seguimiento (ypT0 vs T ≥1 y ypN0 vs ypN + categorías). Las metástasis se confirmaron con biopsia o una TC de seguimiento al menos 1 año después de la quimiorradioterapia preoperatoria. Los valores de sensibilidad, especificidad y precisión de las técnicas de imagen se calcularon utilizando fórmulas estándar.La precisión para la estadificación ypT fue del 89% y 92%, y la precisión para ypN fue del 86% y 92% para RM y TEP/RM respectivamente. En comparación con la TC, la TEP / RM diagnosticó correctamente 4 de 5 metástasis, pero no detectó un nódulo metastásico pulmonar. En el 11% de los pacientes, la TEP / RM cambió la estrategia de tratamiento.Este estudio está limitado por su pequeño tamaño de muestra.Si bien la TEP / RM de todo el cuerpo fue más precisa que la RM pélvica sola para la predicción de la respuesta tumoral y ganglionar a la quimiorradioterapia preoperatoria, la técnica funcionó peor que la TC para detectar metástasis pulmonares pequeños.

[Epidemiology, diagnosis, and treatment of pulmonary embolism].

Pulmonary embolism (PE) is a frequent pathology, the mortality of which remains elevated despite the efficacy of anticoagulation. This is mainly due to diagnostic difficulty, resulting from the low sensibility and specificity of clinical signs and routine exams in PE. The best diagnostic approach relies on decision making algorithms based on the determination of a clinical probability, which in turn dictates the choice of specialized exams (C-scan/scintigraphy, venous duplex, angiography and D-dimers). Risk stratification, which is based on the presence of hemodynamic alterations (right ventricular dysfunction, shock) is essential to guide therapy. In case of shock (massive embolism), treatment relies on systemic thrombolysis. In the presence of right ventricular dysfunction without shock (sub-massive embolism), the advantage of thrombolysis over anticoagulation alone has not been clearly demonstrated. In all other cases, as long as no contraindication exists, therapeutic anticoagulation with heparin must be initiated as soon as PE is suspected, since the mortality of this condition is highest in the two first hours following presentation.

[Estimación del aumento global del tiempo de sedentarismo durante los confinamientos de la COVID-19: una revisión sistemática y un metanálisis.]

Las estrategias restrictivas de movilidad derivadas de la pandemia por COVID-19 podrían afectar negativamente al estado de salud de la población debido a la disminución de los niveles de actividad física. El objetivo de este estudio es estimar el aumento del tiempo de sedentarismo durante los confinamientos en comparación con la situación anterior al brote de COVID-19 en muestras de población adulta de diferentes países del mundo. Se realizó una búsqueda sistemática en tres bases de datos electrónicas, hasta el 27 de febrero de 2021, de estudios que informaran sobre el tiempo total de sedentarismo antes y durante los confinamientos por COVID-19 utilizando una herramienta validada. Se realizó un metanálisis utilizando modelos de efectos aleatorios para calcular las diferencias de medias ponderadas en el tiempo sedentario diario total antes y durante los confinamientos. El análisis se repitió estratificado y comparando por sexo. Se incluyeron 20 estudios, con una calidad metodológica buena (n=15) y regular (n=5). Para el metanálisis se agruparon los datos de 18 estudios, con 47.245 participantes. Los confinamientos por COVID-19 en todo el mundo condujeron a un aumento medio ponderado de 2,40 horas diarias en el tiempo total de comportamiento sedentario (intervalo de confianza del 95%: 1,95; 2,85). El análisis estratificado y comparativo por sexo en 8 estudios indicó un aumento similar para mujeres (n=20.455) y hombres (n=11.825). El tiempo total de sedentarismo diario aumentó en 2,40 horas en todo el mundo durante los confinamientos en comparación con la situación anterior al brote de COVID-19, sin diferencias significativas entre sexos.

[The clinical features of 516 patients with acute pulmonary thromboembolism].

To evaluate the clinical signs and symptoms of acute pulmonary thromboembolism (PTE) and the improvement after thrombolytic and anticoagulant therapy. 516 patients with a first episode of PTE were included in the multicenter randomized study with prospective data collection: 246 with massive and sub-massive PTE and 270 with non-massive PTE. Thrombolytic agents (urokinase or rt-PA randomized) were used for massive and sub-massive PTE and anticoagulant agents (IV infusion of unfractioned heparin or subcutaneous of low-molecular-weight heparin randomized) were administered for non-massive PTE. All patients were submitted to symptoms (such as dyspnea, chest pain, cough, haemoptysis, syncope, etc) and signs (including lung and heart signs) surveillance before treatment and 14 days after treatment were calculated. The percentages of clinical features on the day of before treatment, and 1, 4, 7, 10 and 14 days after treatment. Dyspnea (88.6%), chest pain (59.9%, include angina pain and pleuritic pain) and cough (56.2%) were the most frequent initial symptoms. Hemoptysis presented in only 26.0% of all patients. Increase of respiratory rate was the most frequent signs (51.7%). Syncope and low body pressure (or shock) were seen in 22.8 % and 21.5% of the patients with massive and sub-massive PTE respectively. Cyanosis (45.9%) and increased S(2)P (63.0%) were the most common signs in this group. All symptoms and signs cleared progressively from the pre-treatment evaluation to the 14 day follow-up examination. Dyspnea is the most common symptom of acute PTE, and is aggravated with the degree of PTE. Tachypnea is the most common sign. Thrombolytic and anticoagulant therapy can improve the clinical features of acute PTE markedly.

Introducción: la desnutrición intrahospitalaria se ha descrito hace más de 70 años como un problema frecuente. En México se reportan cifras de entre el 20% al 50%; sin embargo no se ha estudiado su prevalencia ni su asociación con la morbilidad y mortalidad hospitalaria.Objetivos: evaluar el estado nutricional y su relación con la morbimortalidad hospitalaria en pacientes mexicanos.Métodos: cohorte prospectiva de pacientes que ingresaron en un hospital de referencia para una estancia hospitalaria mayor de 5 días. Se capturó peso, talla, índice de masa corporal (IMC), estado nutricional de acuerdo con la valoración global subjetiva (VGS) a su ingreso y egreso hospitalario, así como diagnóstico médico, complicaciones y mortalidad. Los datos fueron analizados mediante la prueba T de Student, prueba Chi-cuadrado y prueba Exacta de Fisher.Resultados: se incluyeron 610 pacientes en total, con un promedio de edad de 50,8 ± 17,32 años, 267 mujeres (43,8%) y 343 hombres (56,2%). Del total, 154 fueron catalogados con sospecha de desnutrición o desnutrición (pacientes expuestos, 25,2%) y 456 bien nutridos (pacientes no expuestos, 74,8%), con una relación de 1 a 3. La morbilidad total de la cohorte tuvo un RR = 2,70, IC 95 % (2,06-3,55) y la mortalidad con un RR = 2,64, IC 95% (1,74-4,0), siendo ambas estadísticamente significativas (p = 0,001).Conclusiones: el diagnóstico de desnutrición al ingreso hospitalario constituye un factor de riesgo para el desarrollo de complicaciones y mortalidad. Este padecimiento al ingreso en comparación con el paciente que no presenta desnutrición incrementó el riesgo de mortalidad hasta en 2.64 veces.

[The best of thrombosis and thromboembolic disease in 1999].

1999 has been a good year in the field of innovation in thrombosis. In coronary syndrome without ST elevation: low molecular weight heparin has been confirmed to be more effective than non-fractionated heparin (enoxaparin) and to improve the prognosis of non-revascularised patients (dalteparin) after the hospital phase; hirudin has been shown to be more effective in terms of incidence of myocardial infarction and recurrence of angina than non-fractionated heparin without a higher incidence of bleeding complications; the anti-GP IIb-IIIa (abciximab) has confirmed all its advantages at 6 months and 1 year after a coronary event. The association of heparin and aspirin, which has been the mainstay of antithrombotic treatment of acute coronary syndromes without ST elevation, will soon be improved upon at the beginning of the third millennium. In myocardial infarction, medical thrombolysis has probably reached a turning point in its history. The association of half doses of rt-Pa and anti-GP IIb-IIIa has been shown to be more effective in obtaining good reflow than the thrombolytic agent alone at conventional doses. These results were obtained without any increase in bleeding complication. The same anti-GP IIb-IIIa also improve mechanical revascularisation by optimising reperfusion after the 24th hour. This benefit is rapidly transformed into reduced left ventricular dysfunction. Pulmonary embolism remains a critical illness as the ICOPER registry reports a 3 year mortality of nearly 16%. This emphasises the importance of early diagnosis which is usually possible without resorting to invasive procedures and by modulating all the results of paraclinical investigations with respect to the pretest clinical probability.

[Circulatory support with venoarterial ECMO in a patient with biventricular Takotsubo cardiomyopathy].

La cardiomiopatía de Takotsubo es una entidad caracterizada por disfunción ventricular aguda y transitoria, la cual está generalmente relacionada a un evento desencadenante (estrés emocional o físico) y que, por lo general, se presenta con disfunción sistólica regional del ventrículo izquierdo, aunque hasta en un 30% puede ser biventricular. Según su severidad, en algunos casos puede condicionar choque cardiogénico refractario a manejo con inotrópicos y vasopresores, por lo que para estos casos deben considerarse los dispositivos de asistencia circulatoria. Presentamos el caso de una paciente joven a quien se realizó cambio valvular pulmonar con prótesis biológica, la cual siete semanas posteriores a la cirugía acudió al servicio de urgencias con derrame pericárdico y fisiología de tamponade secundario a síndrome pospericardiotomía. Por tal motivo se le practicó ventana pericárdica, sin embargo durante el transquirúrgico presentó cardiomiopatía de Takotsubo biventricular que le condicionó choque cardiogénico con insuficiencia mitral y tricúspidea severas y refractariedad a tratamiento médico, así como a balón intraaórtico de contrapulsación (BIAC), por lo cual requirió soporte circulatorio con ECMO venoarterial durante 5 días.

[Value of transthoracic Doppler echocardiography in the diagnosis and management of massive pulmonary embolism].

We report the case of a 62-year-old man with massive pulmonary embolism and severe hemodynamic impairment. Transthoracic Doppler echocardiography was fundamental in confirming the diagnosis by direct visualization of intra-atrial thrombus and signs of right chamber overload. It allowed prompt administration of thrombolytic drug and follow-up monitoring. Doppler echocardiography is a non-invasive, available technique and its early application should be considered in the evaluation of patients with suspected massive pulmonary embolism.

[Perforación de colon sigmoides secundaria a endometriosis. Reporte de un caso].

La endometriosis es la presencia de glándulas endometriales o estroma viable fuera de la cavidad uterina, que afecta aproximadamente al 2-10% de las mujeres en edad reproductiva<sup1</sup. Es común la afección de estructuras pélvicas, incluyendo el intestino. La perforación del colon por endometriosis es muy rara y representa una urgencia quirúrgica. Mujer de 28 años con cuadro de dolor abdominal en fosa iliaca derecha y hueco pélvico, fiebre y náuseas. Se realiza laparotomía exploradora con hallazgo de perforación de colon sigmoides, que requiere resección de la lesión y colostomía terminal, encontrando como diagnóstico definitivo endometriosis. La perforación de intestino o de colon es una complicación poco frecuente, pero de gravedad, que debemos tener siempre presente como sospecha ante un cuadro de abdomen agudo en una paciente en edad fértil y con antecedentes de haber presentado sintomatología gastrointestinal intermitente. Endometriosis is the presence of endometrial glands or viable stroma outside the uterine cavity, which affects approximately 2-10% of women of reproductive age 1. Pelvic structures, including the bowel, are commonly affected. Perforation of the colon by endometriosis is very rare and represents a surgical emergency. A 28-year-old female patient with abdominal pain in the right iliac fossa and pelvic cavity, fever and nausea, exploratory laparotomy is performed with the discovery of sigmoid perforation of the colon, requiring resection of the lesion and terminal colostomy, finding as definitive diagnosis endometriosis. Bowel or colon perforation is a rare but serious complication, which should always be kept in mind as a suspicion of acute abdomen in a female patient of reproductive age and with a history of intermittent gastrointestinal symptoms.

[The role of 2D-doppler electrocardiography in the early diagnosis of massive acute pulmonary embolism and therapeutic monitoring].

Early diagnosis is important for the prognosis of patients affected with pulmonary embolisms. The mortality rate ranges from 30% in untreated cases to 10% in cases getting early treatment. In this context, it is essential to obtain a correct diagnosis in order to start the best treatment for each patient. The aim of our study is to evaluated the contribution of mono- bidimensional echocardiography and color-doppler for the early diagnosis of acute massive pulmonary embolism. We examined 23 patients (14 women with a mean age of 67 +/- 13 years; 9 men with a mean age of 58 +/- 16 years) who were referred to us for observation over a 30-month period. These patients had been admitted to the intensive care unit for suspected acute massive pulmonary embolism and the diagnosis was subsequently confirmed by a pulmonary scintigraphy. None of the 23 patients showed a positive case history of previous heart disease and/or pulmonary disease. The patients were checked using 2D-doppler echocardiography, 120 +/- 45 minutes from the onset of the symptoms. They were then divided into two groups (A and B) based on the presence or absence of thromboembolus in the right cavity of the heart. Seven patients (30%) revealed thromboemboli and were treated effectively with rt-PA (100 mg/2 hours). An increase in the size of the right ventricle with an affected rate RV/LV > 0.6 and the abnormal kinetics of the ventricular septum proved to be the most sensitive parameters for right ventricular overload, as signs of acute massive pulmonary ambolisms were observed in all 23 patients. Tricuspid regurgitation speed (from 2.9 to 3.6 m/sec) and peak systolic pulmonary pressure (67 mmHg) were recorded in all patients. Our observations suggest that the hemodynamic effects of an acute massive pulmonary embolism can be enumerated and monitored by analyzing ventricle size and septum kinetics. To summarize, echocardiography proved to be a simple and realistic test. It enabled correct diagnosis and made it possible not only to start thrombolytic therapy without requiring other exams, but also to monitor and evaluate the effects of this therapy.

[Preterm neonate with spontaneous intestinal perforation of very early presentation].

Introducción: La perforación intestinal espontánea es una condición que afecta principalmente a neonatos pretérmino. Caso clínico: Se presenta el caso de un neonato pretérmino de 26 semanas de gestación con neumoperitoneo en las primeras 24 horas de vida. Por lo precoz del cuadro y los hallazgos radiológicos, la primera hipótesis diagnóstica fue una perforación gástrica. Sin embargo, en la laparotomía se encontró una perforación ileal única, sin hallazgos de enterocolitis. Conclusiones: La perforación intestinal espontánea se ha asociado con intervenciones médicas, como el uso concomitante de esteroides e indometacina. Otras intervenciones, como el uso de magnesio prenatal y la colocación de surfactante pulmonar de forma mínimamente invasiva, se han propuesto como factores de riesgo para su desarrollo. En la actualidad, deben evaluarse la perforación intestinal espontánea y sus asociaciones. Las presentes y futuras investigaciones podrían contribuir a aclarar el papel de las intervenciones mencionadas en la revisión preliminar de la literatura.

[First diagnostic choice in patients with high clinical suspicion of pulmonary thromboembolism: helical CT or ventilation/perfusion pulmonary scintigraphy?].

Comparative analysis about helical CT (ThC) vs ventilation-perfusion pulmonary scintigraphy (V/P Sc) diagnosis effectiveness, as a first diagnosis technique in patients with high clinical suspicion of pulmonary thromboembolism (PT). Prospective study of 30 patients with high clinical suspicion and high Dimer-D levels (> 250 microg/l). The diagnosis was defined as anticoagulant therapeutic prescription and posterior clinical evolution. V/P Sc were performed to each patient within the next 48 h (an average of 14.8 h) after TCh, without anticoagulant treatment. We classified the scintigrams according to the PIOPED criteria and hTC images as positive, negative and indeterminated. In sixteen patients final diagnosis was PT: in 9 both techniques were positive; in 5 scintigraphy was positive with normal hTC and in 1, hTC was normal with negative scintigraphy. The last case was an indeterminated hTC with negative scintigraphy. In fourteen patients, final diagnosis was non-PT: in 6 both techniques were negative; in 7 scintigraphy was negative with positive hTC and in 1, both results were indeterminated. The sensitivity, specificity, positive predictive value, negative predictive value and efficiency were respectively 87.5, 100, 100, 87.5 and 93 % for V/P Sc and 62, 50, 58.8, 53.8 and 53 % for TCh. V/P Sc has better PT diagnosis reliability. It is recommended to do V/P Sc in all patients with high clinical suspicion of PT.

A case report of fat embolism syndrome: Treatment and neurological and cognitive rehabilitation

Se reporta el proceso de recuperación y rehabilitación neurológica y cognitiva de una mujer joven que desarrolló un síndrome de embolia grasa con repercusiones neurológicas, después de sufrir un politraumatismo. La paciente era una mujer de 21 años de edad con fractura cerrada de húmero y fémur izquierdos, que presentó un síndrome de embolia grasa, neumotórax izquierdo e hipertensión pulmonar, en las primeras 24 horas después de un accidente. Estuvo hospitalizada un mes y quedó con varios déficits neurológicos centrales, como infartos 'lacunares' y necrosis cortical laminar occipital, así como limitaciones en la bipedestación, la marcha, la visión y las funciones cognitivas. A partir del primer mes después del alta hospitalaria, se comenzó un proceso integral de rehabilitación neurológica y cognitiva en casa, y posteriormente, en una unidad médica de rehabilitación. Durante los primeros dos años después del accidente, la paciente recibió estimulación sensorial, sensoperceptiva y motora, así como rehabilitación motora y visual intensiva. Una vez se recuperó físicamente, se inició un proceso de rehabilitación neuropsicológica. Seis años después del accidente, la paciente terminó sus estudios universitarios y hoy está laboralmente activa. El proceso de rehabilitación neurológica es complejo, individual y difícil, aunque no imposible, y no se puede estandarizar un patrón de recuperación para todos los pacientes. Si bien existe la recuperación espontánea, la cual se da en los primeros seis meses, el caso aquí reportado demuestra que, en la fase crónica, la recuperación se puede lograr, pero requiere de evaluaciones y técnicas coordinadas de rehabilitación neurológica.

[Diagnosis of pulmonary embolism].

Accurate diagnosis of pulmonary embolism is essential to minimize morbidity and mortality caused by failure to treat when necessary or by inappropriate treatment. Because clinical symptoms and signs are nonspecific, it is impossible to prove the diagnosis solely on clinical grounds. The diagnosis requires high level of suspicion, estimation of the pretest clinical likelihood of embolism, and judicious use of objective investigations (scintigraphy, computed tomography, or angiography) to confirm or refute the suspicion. The choice of tests depends on the availability of these tests, the hemodynamic state of the patient, and the presence of other cardiopulmonary diseases. Despite the availability of most accurate tests, pulmonary embolism will continue to be missed if not first considered by the physician.

Management, Functional Outcomes, and Quality of Life After Development of Pelvic Sepsis in Patients Undergoing Re-Do Ileal Pouch Anal Anastomosis.

The data on management and outcomes of pelvic sepsis after re-do IPAA are scarce. The aim of this study is to report our management algorithm of pelvic sepsis in the setting of re-do IPAA and compare functional outcomes and quality of life after successful management of pelvic sepsis with a no sepsis control group. This is a retrospective cohort study. This investigation is based on a single academic practice group experience on re-do IPAA. Patients who underwent re-do IPAA for ileal pouch failure between September 2016 and September 2020 were included in the study. Management of pelvic sepsis was reported. Functional outcomes, restrictions, and quality-of-life scores were compared between the sepsis and no sepsis groups. One-hundred ten patients were included in our study, of whom 25 (22.7%) developed pelvic sepsis. Twenty-three patients presented with pelvic sepsis before ileostomy closure, and 2 patients presented with pelvic sepsis after ileostomy closure. There were 6 pouch failures in the study period due to pelvic sepsis. Our management was successful in 79% of the patients with median follow-up of 26 months. Treatments included interventional radiology abscess drainage (n = 7), IV antibiotics alone (n = 5), interventional radiology drainage and mushroom catheter placement (n = 1), mushroom catheter placement (n = 1), and endoluminal vacuum-assisted closure (n = 1). Average number of bowel movements, urgency, incontinence, pad use, and seepage were comparable between the pelvic sepsis and no pelvic sepsis groups ( p > 0.05). Lifestyle alterations, Cleveland Global Quality of Life scores, and happiness with the results of the surgery were similar ( p > 0.05). This study is limited by its low study power and limited follow-up time. Pelvic sepsis is common after re-do IPAA, and management varies according to the location and size of the abscess/sinus. If detected early, our management strategy was associated with high pouch salvage rates. See Video Abstract at http://links.lww.com/DCR/B823 .

Los resultados funcionales, las restricciones y las puntuaciones de calidad de vida, se compararon entre los grupos con sepsis y sin sepsis.RESULTADOS:Se incluyeron 110 pacientes en nuestro estudio, de los cuales 25 (22,7) desarrollaron sepsis pélvica. Veintitrés pacientes presentaron sepsis pélvica antes del cierre de la ileostomía y 2 pacientes presentaron sepsis pélvica después del cierre de la ileostomía. Hubo 6 fallas de la bolsa en el período de estudio debido a sepsis pélvica. Nuestro manejo fue exitoso en el 79% de los pacientes con una mediana de seguimiento de 26 meses. Los tratamientos incluyeron drenaje de abscesos IR (n = 7), antibióticos intravenosos solos (n = 5), drenaje IR y colocación de catéter en forma de hongo (n = 1), colocación de catéter en forma de hongo (n = 1) y cierre endoluminal asistido por vacío (n = 1). El número promedio de evacuaciones intestinales, urgencia, incontinencia, uso de almohadillas y filtraciones fueron comparables entre los grupos con sepsis pélvica y sin sepsis pélvica ( p > 0,05). Las alteraciones del estilo de vida, las puntuaciones de la Calidad de vida global de Cleveland y la felicidad con los resultados de la cirugía fueron similares ( p > 0,05).LIMITACIONES:Este estudio está limitado por su bajo poder de estudio y su tiempo de seguimiento limitado.CONCLUSIONES:La sepsis pélvica es común después de la reconfección de anastomosis anal de la bolsa ileal y el manejo varía según la ubicación y el tamaño del absceso / seno. Si se detecta temprano, nuestra estrategia de manejo se asoció con altas tasas de recuperación de la bolsa. Consulte Video Resumen en http://links.lww.com/DCR/B823 .

[Association of D-dimer and helicoidal thoracic scanner for diagnosis of pulmonary embolism. Prospective study of 106 ambulatory patients].

Ventilation/perfusion pulmonary scintigraphy (PS), the current mainspring in the diagnosis of pulmonary oedema (PE), is frequently non-conclusive. The objective of this study was to determine, prospectively, the diagnostic value of the association of D-dimers and helicoidal thoracic scanner (HTS) in a continuous series of ambulatory adults with suspected PE and admitted to a cardiologic emergency unit. Exclusion criteria were as follows: symptoms or clinical signs of seventy, contraindication for HTS and/or on pulmonary angiography, curative anticoagulant therapy for more than 48 hours, history of PE less than 3 months before or the impossibility of conducting all the examinations with 48 hours. All the patients underwent determination of D-dimers by rapid ELISA test, HTS and 2 reference examinations, venous Doppler of the lower limbs and a PS, completed by pulmonary angiography if the PS did not permit diagnosis and the venous Doppler was negative. One hundred and six patients were selected over a recruitment period of 18 months. The prevalence of PE was of 45% (48/106). Forty-four of the 48 PE of the series were central form. HTS was considered dubious in 10 patients (10.4%, PE+ n = 2, PE- n = 8). The results of D-dimers were negative in only 34.5% patients without PE (20/58). Pulmonary angiography was necessary in 15 patients. The negative and positive predictive values of D-dimers were respectively of 100 and 55.8% (48/86) and those of HTS respectively 100 (46/46) and 92% (46/50). The diagnostic strategy of clinical suspicion of PE, starting with determination of D-dimers by rapid ELISA test followed by helicoidal thoracic scanner in the case of a positive result, was particularly effective in this series of patients with a high prevalence of PE. These results must be confirmed in a larger series and in a general emergency unit.
