Background Very few prior studies have investigated the presence of ascites as a prognostic factor in children with cirrhosis. To the best of our knowledge, there are no prior studies evaluating the relationship between severity of ascites and patient survival in children with biliary atresia and cirrhosis. Aims To evaluate the association between severity of ascites and survival of children with cirrhosis and ...
A atresia biliar apresenta etiopatogenia complexa. Casos com e sem anomalias congênitas extra-hepáticas associadas podem representar distintos grupos etiopatogênicos. Entre as anomalias histopatológicas envolvidas com a doença têm sido descritas malformação de placa ductal e alterações nos ramos da artéria hepática. No presente estudo foram avaliadas essas anormalidades em 47 casos de atresia biliar por ocasião...
Abstract—Three-dimensional datasets from biological tissues have increased with the evolution of confocal microscopy. Hepatology researchers have used confocal microscopy for investigating the microanatomy of bile ducts. Bile ducts are complex tubular tissues consisting of many juxtaposed microstructures with distinct characteristics. Since confocal images are difficult to segment because of the noise introduce...
A diferenciação diagnóstica entre colestase extra-hepática e colestase intra-hepática no neonato é um desafio que exige solução antes das primeiras oito semanas de vida. Este estudo compara os resultados da cintilografia de vias biliares seqüencial de 24 horas, do Índice Hepático e do estudo de variáveis histopatológicas hepáticas na diferenciação diagnóstica das causas da colestase neonatal de 49 pacientes int...
Biliary atresia (BA) seems to be a multifactorial disorder in which environmental factors interact with the patient’s genetic constitution. This study aimed to analyze information concerning environmental risk factors associated with BA in southern Brazil. A case-control study with mothers of patients with BA and mothers of patients with cystic fibrosis (CF) was conducted. Inquiry included questions related to ...
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and is characterized by multistage formation. The presence of ductular reaction, cytokeratin 7 positivity (PCK7), and increased levels of gamma glutamyltransferase (γGT) has been observed during liver carcinogenesis and contribute to tumor progression. Our goal was to evaluate the ductular reaction in multistage carcinogenesis and...
