Bile duct cyst type V (Caroli's disease): surgical strategy and results.

Background: Caroli's disease (CD) is a benign congenital disorder characterized by segmental cystic dilatation of the intrahepatic biliary ducts. Therapeutic strategy includes medical treatment, percutaneous, endoscopic or surgical drainage of the affected bile ducts, liver resection or transplantation. The aim of this study was to analyse the results and long-term follow-up of a consecutive series of patients who underwent surgical treatment for CD.

Liver resection for non-colorectal, non-neuroendocrine metastases: analysis of a multicenter study from Argentina.

Background And Aim: Resection of colorectal liver metastases has become a standard of care, although the value of this procedure in non-colorectal non-neuroendocrine (NCRNNE) metastases remains controversial and is still a matter of debate. The aim of the study was to determine the utility of liver resection in the long-term outcome of patients with NCRNNE metastases.

Material And Methods: The records of 106 patients who underwent liver resection for NCRNNE metastases in the period 1989 to 2006 at 5 HPB Centers in Argentina were analyzed.

Evaluation of a third generation anti-HCV assay in predicting viremia in patients with positive HCV antibodies.

The most practical screening test for hepatitis C virus antibodies are second and third- generation enzyme immunoassays. We evaluated the usefulness of the third generation microparticle enzyme immunoassay (MEIA) in predicting HCV viraemia in anti-HCV positive patients. Serum samples from 106 patients with positive anti-HCV were obtained.

Transthyretin familial amyloidotic polyneuropathy: histopathological study of the explanted livers.

FAP is an autosomal dominant inherited disease, characterized by systemic deposition of amyloid fibrils in various tissues. The purpose of this study is to describe the gross and microscopic findings of the explanted livers for FAP.10 patients were transplanted for FAP at our institution.

How to distinguish normal liver from chronic hepatitis in anti-HCV positive individuals with normal alanine aminotransferase levels.

The aim of this study was to characterize the biochemical, virological and histological profile of patients with HCV infection and persistently normal alanine aminotransferase levels (PNALT) in order to discriminate between normal liver and chronic hepatitis. Twenty eight anti-HCV positive patients with PNALT were studied. Twelve (42.

Combination therapy with hydroxyurea versus without hydroxyurea as first line treatment options for antiretroviral-naive patients.

Purpose: This study analyzed whether combination therapy with hydroxyurea (HU) could be considered as first line treatment for antiretroviral-naive patients.

Method: The prospective open-label study was carried out from March 1996 to May 2000. The antiretroviral treatments were treatment 1-didanosine 400 mg/day, stavudine 60/80 mg/day, and HU 500 mg/day; treatment 2-two nucleosides plus a protease inhibitor; treatment 3-didanosine, indinavir, and HU (500-1,000 mg/day).

Liver transplantation in transthyretin familial amyloid polyneuropathy: first report from Argentina.

This is the first report from Argentina of liver transplantation in patients with transthyretin related familial amyloidotic polyneuropathy. The aims of the study were to analyze the clinical characteristics of this new focus and evaluate the postoperative complications and long term follow up. Five of ten patients evaluated underwent liver transplantation.

Chagas' disease in patients with kidney transplants: 7 years of experience 1989-1996.

Chagas' disease was present in 17.22% of persons undergoing kidney transplantation in an Argentine Hospital. The criterion for attributing reactivation of chronic Chagas' disease and transmission of Trypanosoma cruzi to grafts was detection of parasites in blood (patent parasitemia) or tissues.
