Systematic review with meta-analysis: The effect of vitamin E supplementation in adult patients with non-alcoholic fatty liver disease.

Background And Aim: Νon-alcoholic fatty liver disease (NAFLD) is estimated to be the most common cause of end-stage liver disease in the next years. Vitamin E has shown beneficial effects as a possible "scavenger" of oxidative stress products, which play a major role in pathogenesis of the disease. The purpose of the present meta-analysis is to investigate the effects of vitamin E supplementation in biochemical and histological parameters in adult patients with NAFLD.

The role of capsule endoscopy in the evaluation and treatment of obscure-overt gastrointestinal bleeding during daily clinical practice: a prospective multicenter study.

Objective: Capsule endoscopy (CE) is most commonly performed to evaluate obscure gastrointestinal bleeding (GIB). However, at present the role of CE in patients with obscure-overt GIB especially during daily clinical practice is unknown. The aim of the present study was to investigate the diagnostic yield and the impact of CE on the management of patients with obscure-overt GIB.

Inflammatory bowel disease: Greek patients' perspective on quality of life, information on the disease, work productivity and family support.

Background: The aim of this study was to identify inflammatory bowel disease (IBD) patients' perspectives regarding everyday life issues.

Methods: From October 2010 till April 2011, 1,181 IBD patients completed an anonymous questionnaire through the internet (827 cases) or at the outpatient clinic of the participating centers (354 cases), aiming to identify: a) the impact of disease on social life, emotional status and work productivity; b) the source of disease information; and c) the level of support from family members and friends.

Results: Fifty-five percent of the patients reported that IBD interferes with their social life, while 65% felt stressed, 60% depressed and 19% tired because of it.

Diagnostic yield and clinical impact of wireless capsule endoscopy in patients with chronic abdominal pain with or without diarrhea: a Greek multicenter study.

Background: Wireless capsule endoscopy has become the gold standard for the examination of small bowel. However, its role in the evaluation of patients suffering from chronic abdominal pain is not yet clearly defined. We conducted an open-label prospective multi-center study to evaluate the yield and clinical outcome of capsule endoscopy in patients with chronic abdominal pain with/without diarrhea.
