Update on the role of Rifaximin in digestive diseases

Various environmental factors affecting the human microbiota may lead to gut microbial imbalance and to the development of pathologies. Alterations of gut microbiota have been firmly implicated in digestive diseases such as hepatic encephalopathy, irritable bowel syndrome and diverticular disease. However, while these three conditions may all be related to dysfunction of the gut-liver-brain axis, the precise pa...

Clinical course in Crohn's disease: factors associated with behaviour change an...

Background: Crohn’s disease (CD) is a chronic and progressive disease that changes its behaviour over time. Transmural inflammation in CD leads to stricturing and/or penetrating complications. Aim: To evaluate the frequency of long-term progression of CD phenotypes, the need of abdominal surgery, and the main factors associated with these outcomes. Methods: A retrospective study was conducted with a prospective...

Acute diverticulitis and subsequent colonoscopy: instigating an old discussion

Atraso pubertário: um diagnóstico tardio

Introdução: O atraso pubertário é uma patologia frequente na consulta de Endocrinologia. Várias doenças podem estar subjacentes a este problema, sendo a doença inflamatória intestinal, mais concretamente a doença de Crohn, uma das doenças crónicas mais associadas. Caso clínico: Adolescente, sexo feminino, de 16 anos, sem antecedentes patológicos relevantes, referenciada à consulta de Pediatria por atraso pubert...

Updating predictors of endoscopic recurrence after ileocolic resection for Croh...

Background/Aims: Identifying predictors of endoscopic recurrence (ER) has become very important to guide the decision of postoperative strategy. This study aimed to determine the rate of endoscopic recurrence until 12 months after ileocolic resection for Crohn disease (CD) in a cohort and identify its possible predictors. Materials and Methods: We conducted a retrospective single-center study that included pati...

Upper gastrointestinal bleeding risk scores: who, when and why?

Upper gastrointestinal bleeding (UGIB) remains a significant cause of hospital admission. In order to stratify patients according to the risk of the complications, such as rebleeding or death, and to predict the need of clinical intervention, several risk scores have been proposed and their use consistently recommended by international guidelines. The use of risk scoring systems in early assessment of patients ...

Virtual chromoendoscopy improves the diagnostic yield of small bowel capsule en...

Background: Small bowel capsule endoscopy represents the initial investigation for obscure gastrointestinal bleeding. Flexible spectral imaging colour enhancement (FICE) is a virtual chromoendoscopy technique designed to enhance mucosal lesions, available in different settings according to light wave-length - FICE1, 2 and 3. Aims: To compare the diagnostic yield of FICE1 and white light during capsule endoscopy...

Improving diagnostic yield in obscure gastrointestinal bleeding - how virtual c...

Background and aim: A significant proportion of patients presenting with obscure gastrointestinal bleeding (OGIB) have negative small bowel capsule endoscopy (SBCE) examinations, and yet remain at risk of rebleeding. We aimed to evaluate whether a second-look review of SBCE images using flexible spectral color enhancement (FICE) may improve the detection of potentially bleeding lesions. Materials and methods: T...

Impact of the age of diagnosis on the natural history of ulcerative colitis

Background: Ulcerative colitis (UC) has a recognized phenotypic heterogeneity. Some studies suggest that age at diagnosis may influence features and natural history of the disease. Aim: This study aimed to compare patients', disease's and treatment's features between Portuguese patients diagnosed before and after the age of 40-years-old. Methods: Retrospective single-center study that included 310 patients with...

Small bowel capsule endoscopy in obscure gastrointestinal bleeding : normalcy i...

BACKGROUND/AIM: Small bowel capsule endoscopy (SBCE) is currently a fundamental tool in the etiological study of obscure gastrointestinal bleeding (OGIB). However, the impact of a negative exam and the risk of rebleeding are not entirely known. The aim of this study was to evaluate the outcomes of patients with OGIB and a negative SBCE examination in terms of follow-up duration, additional diagnostic studies, a...
