Portal hypertension as an uncommon presentation of hepatic epithelioid hemangioendothelioma: a case report.

Hepatic epithelioid hemangioendothelioma (HEHE) is a vascular tumor with a low incidence rate. We report a case of a 26-year-old man who was referred to our hospital with a misdiagnosis of liver cirrhosis. On physical examination, ascites was noted. Chest and abdominal computer tomography scans showed coalescent lesions involving the peripheral liver with heterogeneous contrast enhancement and portal vein dilation due to portal hypertension. Extrahepatic metastasis was not observed. The biopsy with immunohistochemical stains suggested HEHE (Factor VIII, CD31, and CD34). This report describes an uncommon case of HEHE with non-cirrhotic portal hypertension.

Diagnostic performance of three non-invasive fibrosis scores (Hepamet, FIB-4, NAFLD fibrosis score) in NAFLD patients from a mixed Latin American population.

INTRODUCTION AND AIMS: Several non-invasive scoring systems have been developed and validated worldwide to predict the risk of liver fibrosis in nonalcoholic fatty liver disease (NAFLD). However, information about the performance of these systems in Latin American populations is scarce. Our aim was to evaluate the performance of the Hepamet Fibrosis Score, Fibrosis-4 (FIB-4) and the NAFLD Fibrosis Score (NFS) in a mixed Latin American group of NAFLD patients. METHODS: Clinical, laboratory and liver biopsy data collected from 379 biopsy-proven NAFLD patients from Latin American tertiary health centers were reviewed. Histological fibrosis stages were classified using the Kleiner score. Accuracy was determined, and new fibrosis score thresholds were calculated to better compare the performances of non-invasive tests and to explore their usefulness in excluding fibrosis. RESULTS: The distribution of fibrosis stages among the sample population was as follows: F0 (45%), F1 (27%), F2 (8%), F3 (16%) and F4 (4%). Using modified thresholds, the areas under the ROC curves (AUROC) for Hepamet and FIB-4 (0.73 and 0.74, respectively) to detect significant fibrosis were higher than that of NFS (0.58). However, the AUROCs of the three scores were not significantly different in advanced fibrosis and cirrhosis. To exclude fibrosis, we calculated lower cutoffs than standard thresholds for Hepamet, FIB-4 and NFS with similar performances. CONCLUSION: Thresholds of non-invasive fibrosis scores (Hepamet, FIB-4 and NFS) can be modified to maximize diagnostic accuracy in Latin American patients with NAFLD.

El hemangioendotelioma epitelioide hepático (HEHE) es un tumor vascular con una tasa de incidencia baja. Presentamos el caso de un varón de 26 años que fue remitido a nuestro hospital con un diagnóstico erróneo de cirrosis hepática. En el examen físico se observó ascitis. La tomografía computarizada de tórax y abdomen mostró lesiones coalescentes que afectaban al hígado periférico con realce heterogéneo de contraste y dilatación de la vena porta por hipertensión portal. No se observó metástasis extrahepática. La biopsia con tinciones inmunohistoquímicas sugirió HEHE (Factor VIII, CD31 y CD34). Este informe describe un caso poco común de HEHE con hipertensión portal no cirrótica.

Características de los factores de riesgo cardiovascular en una población urbana y rural de la selva peruana, julio - 2014 / Characteristics of cardiovascular risk factors in an urban and rural population of the Peruvian jungle - July, 2014

Objetivo: Determinar las características del lugar de residencia y los factores de riesgo cardiovascular en una población de la selva peruana en julio 2014. Materiales y métodos: Estudio descriptivo transversal realizado en individuos entre 30 y 74 años sin diagnóstico ni tratamiento de enfermedad cardiovascular en una población urbana y una rural del distrito de Yantaló. La muestra se obtuvo a partir del programa Power Analysis and Sample Size Software (PASS) y estuvo conformada por 268 personas (152 habitantes urbanos y 116 rurales). Los factores estudiados fueron hipertensión arterial (HTA), diabetes mellitus (DM), índice de masa corporal (IMC), índice cintura-cadera (ICC) y tabaquismo. Resultados: La población urbana presentó un mayor porcentaje de HTA (18,4%), mientras que los otros factores de riesgo no presentaron diferencias significativas. Conclusiones: El único factor de riesgo que mostró asociación significativa con el lugar de residencia fue la HTA. En contraste, los otros factores de riesgo del estudio no presentaron diferencias entre ambas poblaciones, lo que demostraría que el distrito de Yantaló se encuentra inmerso en un proceso de transición epidemiológica debido a la urbanización.

Objective: To determine the characteristics of the place of residence and the cardiovascular risk factors in a Peruvian jungle population in July 2014. Materials and methods: A descriptive cross-sectional study conducted in individuals between 30 and 74 years old without a diagnosis of or treatment for a cardiovascular disease in an urban and rural population of the district of Yantaló. The sample was obtained using the Power Analysis and Sample Size Software (PASS) program, and consisted of 268 people (152 urban and 116 rural residents). The studied factors were hypertension (HBP), diabetes mellitus (DM), body mass index (BMI), waist-hip ratio (WHR) and smoking. Results: The urban population had higher rates of hypertension (18.4%), while the other risk factors showed no significant differences between the two populations. Conclusions: The only risk factor that showed a significant association with the place of residence was hypertension. In contrast, the other risk factors of the study showed no differences between the two populations, which demonstrates that the district of Yantaló is involved in a process of epidemiological transition due to urbanization.
