Shunt portosistémico, una causa poco frecuente de hepatitis colestásica en neonatología. A propósito de un caso / Portosystemic shunt, a rare cause of neonatal cholestatic hepatitis. A case report

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.

Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

Factores de riesgo asociados a la pérdida insuficiente o ganancia significativa de peso en pacientes sometidos a cirugía bariátrica / Risk factors associated with insufficient weight loss or significant weight gain in patients undergone bariatric surgery

Introducción. La cirugía bariátrica es efectiva para inducir una rápida pérdida del exceso de peso, pero existen dudas sobre la duración de este efecto a largo plazo. Este estudio buscaba identificar la proporción de pacientes operados que presentaron una pérdida insuficiente o una ganancia significativa de peso y los posibles factores relacionados. Métodos. Estudio de cohorte retrospectivo en pacientes adultos sometidos a cirugía bariátrica. Se describieron variables demográficas y clínicas. Se realizó un análisis multivariado para identificar factores relacionados con un peso fuera de metas posterior a la cirugía. Resultados. Se incluyeron 187 pacientes, 117 con baipás gástrico y 70 con manga gástrica. La mediana de índice de masa corporal preoperatorio fue 41,3 kg/m2 y postoperatorio de 28,8 kg/m2. El 94,7 % de los pacientes en ambos grupos logró una adecuada pérdida del exceso de peso. La ganancia de peso mayor del 20 % se presentó en el 43,5 % de los pacientes, siendo mayor en el grupo de manga gástrica (p<0,004). Los factores independientes para ganancia de peso fueron el sexo masculino (OR 5,5), cirugía tipo manga gástrica (OR 3,4), síndrome de apnea del sueño (OR 2,9) y enfermedad mental medicada (OR 2,8). Conclusión. La cirugía bariátrica produce una pérdida del exceso de peso suficiente en casi la totalidad de los pacientes, pero un buen número recuperan peso luego de 3 años. Los principales factores asociados a ganancia de peso son el sexo masculino y la cirugía tipo manga gástrica

Introduction. Bariatric surgery is highly effective in inducing rapid excess body weight loss but there are doubts about its effect on long-term. This study seeks to identify the number of patients that underwent bariatric surgery who present insufficient weight loss or significant weight gain and the possible related factors. Methods. Retrospective cohort study of adult patients who underwent bariatric surgery. Demographic and clinical variables are described. A multivariate analysis was performed to identify factors related to patient weight outside the set goals postoperatively. Results. 187 patients were included (117 gastric bypass, 70 gastric sleeve). The median preoperative body mass index was 41m/kg2 and 28.8m/kg2 postoperatively. 94.7% of the patients in both groups achieved adequate excess body weight loss. Weight gain (>20%) occurred in 43.5% of the patients, with the probability being higher in the gastric sleeve group (p<0.004). Independent factors for weight gain were male gender (OR 5.5), gastric sleeve surgery (OR 3.4), sleep apnea syndrome (OR 2.9), and mental illness under treatment (OR 2.8). Conclusions. Bariatric surgery produces sufficient loss of excess weight in almost all patients, but a good number of them regain weight after 3 years. The main factors associated with weight gain are male gender and gastric sleeve surgery

Conclusions: young adult patients have poor metabolic control and frequent use of insulins. (Acta Med Colomb 2021; 46. DOI: https://doi.org/10.36104/amc.2021.1902).

Trombosis en el recién nacido / Thrombosis in the newborn

La trombosis en recién nacidos (RN) es una patología infrecuente que se asocia principalmente a catéter venoso central. Su presentación clínica puede ser la de un RN asintomático o con sintomatología variable, según la ubicación y tamaño de la trombosis. El diagnóstico generalmente se realiza con ecografía doppler y exámenes específicos según sea la presentación clínica. Con respecto al manejo, actualmente no existe mucha evidencia en RN, pero se suele utilizar trombolíticos/fibrinolíticos extrapolando las investigaciones de adultos. En esta revisión se detalla sobre epidemiología, fisiopatología, factores de riesgo, presentaciones clínicas, diagnóstico y tratamiento. Existe falta de estudios sobre epidemiología nacional y tratamiento en RN, se plantea la necesidad de estos.

Thrombosis in newborns is an infrequent pathology which is mainly associated with a central venous catheter. Its clinical presentation may be that of an asymptomatic newborn or with variable symptoms, depending on the location and size of the thrombosis. The diagnosis is generally made with Doppler ultrasound and specific examinations depending on the clinical presentation. Regarding management, currently there is not much evidence in newborns, but thrombolytics / fibrinolytics are usually used extrapolating from adult investigations. This review details epidemiology, pathophysiology, risk factors, clinical presentations, diagnosis and treatment. There is a lack of studies on national epidemiology and treatment in newborns, the need for these arises.

Tuberculosis urogenital en un paciente con falla renal, estado del arte / Urogenital tuberculosis in a patient with kidney failure, state of the art

RESUMEN La tuberculosis es una enfermedad infecciosa y frecuente en países en vía de desarrollo. Esta puede causar una amplia variedad de complicaciones y presentaciones atípicas con alta morbimortalidad. De la forma genitourinaria se sospechada muy poco, razón por la cual su diagnóstico se hace, usualmente, de forma tardía o no se realiza. Esto conlleva a consecuencias muy graves en los pacientes, por ejemplo, la enfermedad renal crónica terminal. A continuación, se presenta un reporte de caso de una paciente con la anterior enfermedad, secundaria a una tuberculosis renal bilateral diagnosticada tardíamente y se realiza una revisión de la literatura sobre este tema.

SUMMARY Tuberculosis is a common infectious disease in developing countries, which can cause a variety of complications and atypical manifestations with high morbidity and mortality. The urogenital form is rarely suspected, resulting in delayed diagnosis or even no diagnosis, which can have serious consequences for the patients, such as chronic end-stage renal disease. We report on a patient with chronic end-stage renal failure caused by a delayed diagnosis of bilateral renal tuberculosis and a literature review on this topic.

Objective Analize peritoneal fluid cultures obtaines from patients who underwent emergency surgery. Methods A prospective cohort of emergency abdominal surgical patients were enrolled. Peritoneal fluid cultures were taken and processed according to standarized technique. Results A 39.4% of positive cultures was found. E. coli was the most common bacteria identified. Five positive cultures for P. aeruginosa stand out. E. coli had 25% resistance to ampicillin/sulbactam and 19% for quinolones. Conclusion Resistance found was lower than international reports, but still noteworthy. Knowledge of local bacteria profile and antimicrobial resistance is important for local antibiotic hospital policy.

Caracterización de eventos de hipoglicemia en pacientes diabéticos y no diabéticos atendidos en un servicio de urgencia / Hypoglycemia in an emergency room: review of 251 cases

Background Hypoglycemia is the main limitation for the achievement of glycemic goals in the treatment of diabetes. Aim To assess the incidence of hypoglycemia in an emergency department. To characterize and identify which patients are at higher risk of having it. Material and Methods We reviewed the electronic records of patients discharged from an adult emergency room with the diagnosis of hypoglycemia between May 2011 and December 2014. Age, sex, diagnosis of diabetes (DM), antidiabetic therapy, glycosylated hemoglobin, creatinine, destination at time of discharge, blood glucose, impairment of conscience, treatment of the event and predictions were recorded. Results Of 175,244 attentions analyzed, 251 in patients aged 69 ± 17 years (54% women) consulted for hypoglycemia (0.14%). Eighty one percent had a type 2 diabetes, 6% a type 1 diabetes and 12% were non-diabetic. Mean blood glucose was 44.1 mg/dl. In diabetic patients, mean glycosylated hemoglobin was 6.5%. Ninety seven percent had impairment of conscience and 77% were admitted to the hospital. Among patients without diabetes, the main comorbidity was the history of a gastric bypass surgery. In type 2 diabetes, glibenclamide used alone or with other medications was involved in 59% of the events, 87% of patients were older than 65 years with a mean glycosylated hemoglobin of 6.3% and 32% had renal failure. Conclusions The incidence of hypoglycemia was low. There were a significant number of events in older patients with type 2 diabetes mellitus and renal failure, who were treated with glibenclamide. Most of these patients had a glycosylated hemoglobin below accepted recommendations.

Índice C en médicos de dos centros hospitalarios chilenos según el test de competencia moral de Lind / Assessment of moral competence of physicians

Background: Moral competence (MC) in physicians is fundamental, given the increasing complexity of medicine. The "Moral Competence Test" (MCT © Lind) evaluates this feature and its indicator is the C Index (CI). Aim: To explore moral competence and its associated factors among physicians working in Chile. Material and Methods: The MCT was answered by 236 physicians from two medical centers who voluntarily participated in the study. Besides the test, participants completed an encrypted form giving information about gender, years in practice and post-graduate studies. Results: The average CI value of the participants was 20,9. Post-graduate studies had a significant positive influence on CI. There was a significant decrease in CI, between 16 and 20 years of professional exercise. Gender and the area of post-graduate studies did not have a significant influence. Conclusions: The studied physicians showed a wide range of CI which was positively affected by the postgraduate studies performed. The years of professional practice had a negative influence. Expanding training opportunities during professional practice could have a positive effect on CM as measured by CI.

Pancreatectomía córporo-caudal con resección del tronco celíaco por adenocarcinoma de cuerpo pancreático: intervención de Appleby modificada / Distal pancreatectomy with celiac axis resection for adenocarcinoma of the pancreatic body: the modified Appleby procedure

La resección oncológica completa es el único procedimiento que permite la sobrevida a largo plazo en cáncer de páncreas. La afectación de la arteria hepática, tronco celíaco o arteria mesentérica superior constituyen una contraindicación quirúrgica porque se asocia a mal pronóstico y por las dificultades técnicas que implica conseguir la resección oncológica completa. Solo un grupo seleccionado de pacientes con buena respuesta a la quimioterapia y pasibles de resección R0 se benefician de la cirugía de resección del tronco celíaco. A partir de un caso clínico de un adenocarcinoma de páncreas con infiltración de la arteria hepática común y tronco celíaco que tras una buena respuesta a la neoadyuvancia y embolización de la arteria hepática común fue sometido a una esplenopancreatectomía córporo-caudal con resección del tronco celíaco, se realiza una revisión de la literatura sobre el tema y sus aspectos técnicos relevantes. El análisis realizado permite sugerir que en casos debidamente seleccionados la pancreatectomía córporo-caudal con resección del tronco celíaco en bloque es un procedimiento factible, seguro, y con buenos resultados quirúrgicos y oncológicos. En condiciones de respuesta a la quimioterapia neoadyuvante y experiencia del equipo quirúrgico pareciera que esta cirugía podría mejorar el pronóstico y calidad de vida de estos enfermos.

Abstract Complete oncologic resection is the only procedure that enables survival in pancreatic cancer. Compromise of the liver artery, the celiac artery or the superior mesenteric artery constitute a surgical contraidication since it is associated to a bad prognosis and it is technically hard to achieve a complete surgical resection. Only a selected group of patients who respond well to chemotherapy and may be subject to resection benefit from celiac artery resection surgery. A clinical case of adenocarcinoma of the pancreas with infiltration of the common liver artery and the celiac artery underwent a corporeo-caudal pancreatosplenectomy with celiac artery resection after a good response to neoadjuvant therapy and hepatic arterial embolization. Based on this, a review of literature on this issue and its relevant technical aspects was conducted. The analysis performed may suggest that in duly selected cases, corporeo-caudal pancreatosplenectomy with bloc celiac artery resection is a feasible and safe procedure with good surgical and oncologic results. Upon good response to neoadjuvant chemotherapy and an experienced surgical team, this surgery seems to improve prognosis and the quality of life of these patients.

Resumo A ressecção oncológica completa é o único procedimento que permite uma sobrevida em longo prazo a pacientes com câncer de pâncreas. O comprometimento da artéria hepática, tronco celíaco ou artéria mesentérica superior é uma contraindicação cirúrgica porque está associado a um prognóstico ruim e, devido às dificuldades técnicas que implica conseguir a ressecção oncológica completa. Somente um grupo selecionado de pacientes com boa resposta à quimioterapia e que possa ser submetido à ressecção R.0 pode se beneficiar da cirurgia de ressecção do tronco celíaco. A partir de um caso clínico de um adenocarcinoma de pâncreas com infiltração da artéria hepática comum e do tronco celíaco, que depois de apresentar boa resposta à quimioterapia e a embolização da artéria hepática comum, foi submetido a uma esplenopancreatectomia corpo-caudal com ressecção do tronco celíaco, realizou-se uma revisão da literatura sobre o tema e seus aspectos técnicos relevantes. A análise realizada permite sugerir que nos casos devidamente selecionados, a pancreatectomia corpo-caudal com ressecção em bloco do tronco celíaco é um procedimento factível, seguro, com bons resultados cirúrgicos e oncológicos. Quando se reúnem as condições de resposta adequada à quimioterapia neoadjuvante e a experiência da equipe de cirurgia, pareceria que esta intervenção poderia melhorar o prognóstico e a qualidade de vida destes pacientes.
