[Food consumption patterns and risk of gallstone disease (GD): Case and Control Study in Rosario Argentina.].

Introduction: Nutritional exposure is considered the main environmental influence that contributes to gallstone disease (GD).

Aim: The aim of this study was to determine food intakes patters and estimate risk of GD.

Methods: A nested case-control study was carried out within the framework of a previous screening study conducted on a representative sample in Rosario, Argentina.

Peritonitis due to colon mantle cell lymphoma.

Mantle cell lymphoma is a rare and aggressive type of B-cell non-Hodking lymphoma. It can compromise the gastrointestinal tract, sometimes developing an entity known as multiple lymphomatous polyposis. It develops more frequently in males in the sixth decade of life, presenting heterogeneous clinical patterns.

Sentinel Lymph Node Biopsy in Patients With Thick Primary Cutaneous Melanoma.

Background: The clinical value of sentinel lymph node biopsy (SLNB) in patients with thick melanoma is uncertain. The purpose of this study was to investigate the correlations between survival and lymph node status in thick melanomas.

Methods: Of a total of 736 melanoma patients registered between 2000 and 2016, 50 presented with thick melanomas (≥ 4.

Pediatric living donor liver transplant in a recipient with biliary atresia and portal vein duplication-How did we manage it?

Portal vein malformations might occur during the embryonic period, as a consequence of abnormal remodeling of vitelline veins during embryonic life. Patients suffering from biliary atresia are particularly prone to have vascular malformations; although being the most frequent indication for liver transplantation in the pediatric age, portal vein duplication has not been so far associated with biliary atresia, and to the best of our knowledge, there is no-written evidence describing how to manage it when it is first diagnosed while performing a pediatric liver transplant. Therefore, we present a recent case from our group, describing the intraoperative diagnosis of a double portal system in a patient with biliary atresia and failed Kasai.

A nested case-control study on dietary fat consumption and the risk for gallstone disease.

Background: Gallstone disease (GD) incidence and prevalence rates differ between populations. Diet and lifestyle may be involved in GD development. To our knowledge, no study to date has evaluated quantitative data on diet when studying the relationship between fat consumption levels and GD in an Argentinean population.
