RESUMO

Malignant peripheral nerve sheath tumors are frequently associated with neurofibromatosis type 1. They are usually located in the extremities or in the axial area. Its visceral location is very rare and its hepatic origin is infrequent. They tend to be aggressive with a poor response to chemotherapy and radiotherapy, so surgical management is the best treatment option. We present the case of a young man with neurofibromatosis type 1, who presented with hemoperitoneum as a complication of a malignant tumor of the peripheral nerve sheath located in the liver.

RESUMO

Acetaminophen is a drug widely used in the world and easily accessible due to its antipyretic, analgesics characteristics, among others (1); however, exposure to toxic doses causes organic damage and even death. We present the case of an 18-year-old female patient who ingested 40 grams of acetaminophen and developed severe liver dysfunction, being treated with N-acetylcysteine (NAC) antidotal therapy according to the simplified scheme: Scottish and Newcastle Anti-emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presenting improvement in the clinical course and decrease in liver profiles, coagulation disorder, INR and resolution of the condition.

RESUMO

Pneumobilia is a phenomenon associated with the presence of a biliary-enteric fistula or manipulation of the bile duct during procedures or surgical interventions that cause dysfunction of the sphincter of Oddi. A known, but infrequently reported event, is the increase in intraabdominal pressure after closed abdominal trauma, which causes pneumobilia due to a mechanism of retrograde air leakage towards the bile duct. Depending on the general compromise of each patient, the prognosis can vary from a benign condition that only requires conservative management, to being life threatening. We present the case of a 75-year-old male patient who, after suffering a closed thoraco-abdominal trauma, presented with rib fracture and, in addition, gallbladder wall rupture, pneumoperitoneum, pneumobilia, and pneumowirsung, having a favorable clinical course after receiving conservative management.

RESUMO

La obesidad es una patología de importancia a nivel mundial porque conlleva a una alta carga de mortalidad y morbilidad. El balón intragástrico representa una técnica no quirúrgica empleada cada vez con más frecuencia para lograr pérdida de peso. Si bien, este se considera un método seguro, se han reportado algunas complicaciones desde náuseas y vómitos, hasta eventos adversos graves, tales como perforación. La pancreatitis aguda constituye una complicación muy rara del balón intragástrico y se atribuye su efecto a la compresión directa que ejerce sobre el páncreas. Presentamos el caso de una paciente mujer de 21 años, quien después de 7 meses de colocación de balón intragástrico, cursó con dolor abdominal, náuseas y vómitos, asociados a elevación de enzimas pancreáticas. Se hizo diagnóstico de pancreatitis aguda y se corroboró compresión de la cola del páncreas mediante estudio tomográfico. Se decidió retiro del balón mediante endoscopía, cursando luego con evolución favorable.

Obesity is a pathology of importance worldwide because it leads to a high burden of mortality and morbidity. The intragastric balloon represents a non-surgical technique used more and more frequently to achieve weight loss. Although this is considered a safe method, some complications have been reported, from nausea and vomiting to serious adverse events, such as perforation. Acute pancreatitis is a very rare complication of the intragastric balloon, and its effect is attributed to the direct compression it exerts on the pancreas. We present the case of a 21-year-old female patient who, after 7 months of intragastric balloon placement, developed abdominal pain, nausea, and vomiting, associated with elevated pancreatic enzymes. A diagnosis of acute pancreatitis was made and compression of the tail of the pancreas was confirmed by tomographic study. It was decided to remove the balloon by endoscopy, which then progressed favorably.

La neumobilia es un fenómeno asociado a presencia de fístula bilioentérica o manipulación de la vía biliar durante procedimientos o intervenciones quirúrgicas que condicionan disfunción del esfínter de Oddi. Un evento poco reportado, pero ya conocido, es el aumento de la presión intraabdominal tras un trauma abdominal cerrado, que condiciona neumobilia por un mecanismo retrógrado de fuga de aire hacia la vía biliar. Según el compromiso general de cada paciente, el pronóstico puede variar desde un cuadro benigno, que solo requiere un manejo conservador, hasta ser amenazante para la vida. Se presenta el caso de un paciente varón de 75 años, quien después de presentar un trauma toracoabdominal cerrado cursa con fractura costal y, además, ruptura de pared vesicular, neumoperitoneo, neumobilia, y neumowirsung, cursando con evolución favorable tras recibir manejo conservador.

RESUMO

Typhlitis, is also known as neutropenic enterocolitis, affects the cecum and distal ileum. It was frequently encountered in pediatric patients who were undergoing treatment for leukemia. Nonetheless, it can affect adult patients, regardless of the cause of the immunosuppression. We report the case of a 20-year-old patient who was receiving chemotherapy for Osteosarcoma, who had a 6-day history of nausea and vomiting, fever sensation, diarrhea, and diffuse abdominal pain. Physical examination was relevant for hemodynamic instability, a distended and tender abdomen predominantly in the right iliac fossa. The laboratory workup showed severe neutropenia, thrombocytopenia, and electrolyte disturbances. The image studies evidenced edema of the ascending colon and cecum. Treatment was started with vasopressor support, correction of electrolyte alterations, blood cell and platelet transfusion, G-CSF, hydration, broad spectrum antibiotic therapy, initially with adequate clinical and laboratory response. After a few days, he presented lower gastrointestinal bleeding which was treated by conservative management. In conclusion, typhlitis must be suspected in every patient developing neutropenia as a reaction to chemotherapy and who also presents gastrointestinal symptoms, such as nausea, vomiting, diarrhea, and intense abdominal pain.

La tiflitis o también denominada enterocolitis neutropénica afecta el ciego e íleon distal. Fue descrita comúnmente en pacientes pediátricos sometidos a tratamiento para leucemia; sin embargo, puede afectar al paciente adulto independiente de la causa que origine la inmunosupresión. Presentamos el caso de un paciente de 20 años con antecedente de osteosarcoma, quien acude con tiempo de enfermedad de 6 días caracterizado por náuseas y vómitos, sensación de alza térmica, diarrea y dolor abdominal difuso. Al examen físico se encuentra hemodinámicamente inestable, abdomen distendido y se corrobora el dolor abdominal a predominio en fosa iliaca derecha. Los exámenes de laboratorio mostraron neutropenia severa, trombocitopenia y alteraciones hidroelectrolíticas. En los estudios de imágenes la TC evidenció edema de asas delgadas, así como edema de pared del colon ascendente y ciego. Se inició tratamiento con soporte vasopresor, corrección de alteraciones hidroelectrolíticas, transfusión de paquetes globulares y plaquetas, G-CSF, hidratación, terapia antibiótica de amplio espectro, inicialmente con adecuada respuesta clínica y laboratorial. Al cabo de unos días presentó hemorragia digestiva baja como complicación que fue tratada mediante manejo conservador. En conclusión, la tiflitis debe sospecharse en todo paciente que desarrolla neutropenia luego de quimioterapia y que presenta síntomas gastrointestinales como náuseas, vómitos, diarrea y dolor abdominal intenso. El manejo conservador, en pacientes con hemorragia digestiva y tiflitis, que involucra corrección de coagulopatía, transfusión de paquetes globulares e hidratación, puede ser el adecuado en pacientes que no cursan con inestabilidad hemodinámica y logran controlar el sangrado.

RESUMO

INTRODUCTION: Irritable bowel syndrome (IBS) is a chronic functional bowel condition with an average world prevalence of 11.2%. Is associated with multiple factors as female sex, young age, stress, anxiety and depression which can have a negative impact on quality of life. IBS in Peru is not investigated at all specially in the Andean region. The objective of this study is to determine the prevalence and associated factors of IBS in an Andean community from Peru using the Rome IV criteria. MATERIALS AND METHODS: Cross-sectional study in a rural community dedicated to livestock and agriculture in Peru at 3,235 meters above sea level. Questionnaires provided by the Rome Foundation as the Rome IV - Diagnostic questionnaire for adults, Irritable Bowel Syndrome - Symptom Severity Scale and Bristol stool scale were used. RESULTS: 130 residents met the inclusion criteria. 46.9% were males with an average age of 54 years old. 11.54% presented red flags and were not included in the analysis. 13.1% were diagnosed with IBS and 52.9% presented constipation as predominant bowel pattern. 52.9% presented a mild course of the disease. In the chi-square analysis, factors as depression, anxiety, female sex, younger age, liquefied petroleum gas exposure for cooking and education achievement were statistically significant associated to IBS. In the logistic regression analysis, anxiety was the unique independent predictor factor with an OR of 9.6 (95% IC: 1.78-51.82). CONCLUSION: IBS is a prevalent condition in the Andean region and should be managed as a public health issue to improve quality of life.

Introducción : El síndrome del intestino irritable (SII) es una enfermedad intestinal funcional crónica con una prevalencia mundial promedio del 11,2%. Se asocia a múltiples factores como el sexo femenino, la juventud, el estrés, la ansiedad y la depresión que pueden tener un impacto negativo en la calidad de vida. El SII en Perú, no es investigado a profundidad, especialmente en la región andina. El objetivo de este estudio es determinar la prevalencia y factores asociados del SII en una comunidad andina de Perú utilizando los criterios de Roma IV. Materiales y métodos : Estudio transversal en una comunidad rural dedicada a la ganadería y la agricultura en Perú a 3 235 metros sobre el nivel del mar. Se utilizaron cuestionarios proporcionados por la Fundación de Roma como Rome IV - Cuestionario de diagnóstico para adultos, Síndrome del intestino irritable - Escala de gravedad de los síntomas y Escala de heces de Bristol. Resultados : 130 residentes cumplieron los criterios de inclusión. El 46,9% eran varones con una edad media de 54 años. El 11,54% presentó señales de alerta y no fueron incluidos en el análisis. El 13,1% fueron diagnosticados de SII y el 52,9% presentó estreñimiento como patrón intestinal predominante. El 52,9% presentó un curso leve de la enfermedad. En el análisis de chi-cuadrado, factores como depresión, ansiedad, sexo femenino, edad más joven, exposición a gas licuado de petróleo para cocinar y logros educativos fueron estadísticamente significativos asociados con el SII. En el análisis de regresión logística, la ansiedad fue el único factor predictor independiente con una OR de 9,6 (IC del 95%: 1,78-51,82). Conclusión : El SII es una condición prevalente en la región andina y debe ser manejado como un problema de salud pública para mejorar la calidad de vida.

RESUMO

In lower gastrointestinal bleeding (LGIB), it is very important to stratify the risk of LGIB for a proper management. OBJECTIVE: Identity the independent risk factors to mortality and severity (require critical care, prolonged hospitalization, reebleding, re hospitalization, politrasfusion, surgery for bleeding control) in LGIB. MATERIALS AND METHODS: It is an analytic prospective cohort study, performed between June 2016 and April 2018 in a tertiary care hospital. Independent factors were determined using binomial logistic regression. RESULTS: A total of 98 patients were included, of which 13 patients (13,3%) died, and 56 (57,1%) met severity criteria. The independent risk factor for mortality was Glasgow scale under 15, and for severe bleeding were: Systolic blood pressure under 100 mm Hg, albumin lower than 2,8 g/dL. CONCLUSIONS: The frequency of mortality and severe LGIB is high in our population, the principal risk factors were systolic blood pressure under than 100 mm Hg, Glasgow score lower than 15, albumin lower than 2,8 g/dL. Identifying these associated factors would improve the management of LGB in the emergency room.
