Symptomatic Hyponatremia after Bowel Preparation: Report of Two Cases and Liter...
Costa, Juliana Moura; Soares, João BrunoIntroduction: Bowel preparation for colonoscopy and/or colorectal surgery can cause electrolyte imbalances. The risk of electrolyte imbalances seems to be related to the type of bowel cleansing solution, age of patients and comorbidities.Case Report: We report two cases of symptomatic hyponatremia (focal neurological signs and coma) after bowel preparation with sodium picosulfate/magnesium citrate for colonosco...
Será uma refeição ligeira fator de erro na avaliação da dureza hepática por ela...
Caetano, Ana Célia; Lages, Joana; Gonçalves, Bruno; Soares, João Bruno; Gonçalves, Raquel; Rolanda, CarlaIntrodução: A elastografia hepática transitória (EHT) é um método não invasivo de avaliação de fibrose utilizado na doença hepática, principalmente na infeção crónica pelo vírus da hepatite C (VHC). Está demonstrada a sua acuidade na identificação de doentes com fibrose avançada ou cirrose. No entanto, existem fatores capazes de interferir na medição da dureza hepática (DH) para além da fibrose.

Increased hepatic expression of TLR2 and TLR4 in the hepatic inflammation-fibro...
Soares, João Bruno; Nunes, Pedro Pimentel; Afonso, Luís; Rolanda, Carla; Lopes, Paula; Roncon-Albuquerque, R.; Gonçalves, Nádia; Carvalho, Inês BoalWe evaluated expression of TLR2, TLR4 and proinflammatory genes [NF-?B, TNF-a, cyclooxygenase-2 (COX-2)] in liver samples of patients in different stages of liver disease. Fifteen patients with unexplained transaminases elevation (reference group), 22 with viral chronic hepatitis (hepatitis group), 14 with virus-induced severe fibrosis/cirrhosis (cirrhosis group) and 10 with hepatocarcinoma (hepatocarcinoma gro...

Nunes, P. Pimentel; Ribeiro, M. Dinis; Soares, João Bruno; Pinto, R. Marcos; Santos, C.; Rolanda, Carla; Bastos, R. P.; Areia, M.; Afonso, L.BACKGROUND AND STUDY AIM: The reliability and external validity of narrow band imaging (NBI) in the stomach have not been described consistently. The aim of the current study was to describe and estimate the accuracy and reliability of a simplified classification system for NBI in the diagnosis of gastric lesions. METHODS: Consecutive patients undergoing NBI endoscopy at two reference centers (n=85, 33% with dy...
