BACKGROUND Current guidelines recommend performance of oesophago-gastro-duodenoscopy at the time of diagnosis of hepatic cirrhosis to screen for oesophageal varices. These guidelines require people to undergo an unpleasant invasive procedure repeatedly with its attendant risks, despite the fact that half of the people do not have identifiable oesophageal(More)
OBJECTIVE The NOX2 NADPH oxidase complex produces reactive oxygen species and plays a critical role in the killing of microbes by phagocytes. Genetic mutations in genes encoding components of the complex result in both X-linked and autosomal recessive forms of chronic granulomatous disease (CGD). Patients with CGD often develop intestinal inflammation that(More)
OBJECTIVES Congenital portosystemic shunts (CPSSs) are rare but increasingly recognized as a cause of important multisystem morbidity. We present new cases and a systematic literature review and propose an algorithm for the identification and care of affected patients. METHODS We reviewed the charts of consecutive patients seen in our pediatric liver(More)
BACKGROUND AND OBJECTIVES Identification of children who are at high risk for having varices using noninvasive tests would enable the selection of children for future studies of primary prophylaxis of variceal hemorrhage, but this has been inadequately studied. The objective of the study was to derive a noninvasive clinical prediction rule that is able to(More)
BACKGROUND & AIMS The validation of noninvasive tests to diagnose esophageal varices is a priority in children because repeated endoscopic evaluations are too invasive. We measured the ability of a previously developed noninvasive clinical prediction rule (CPR) to predict the presence of esophageal varices in children. METHODS We analyzed data from 108(More)
Bowel preparation is a core issue in colonoscopy, as it is closely related to the quality of the procedure. Patients often find that bowel preparation is the most unpleasant part of the examination. It is widely accepted that the quality of cleansing must be excellent to facilitate detecting neoplastic lesions. In spite of its importance and potential(More)
BACKGROUND AND AIMS Inadequate evidence to guide the management of children with esophageal varices may lead to variation in care and the provision of poor-quality care to some children. The aims of the study were to describe approaches taken by pediatric gastroenterologists for the management of esophageal varices in children, and to determine the(More)
AIM To optimize diagnosis and treatment guidelines for this geographic region, a panel of gastroenterologists, epidemiologists, and basic scientists carried out a structured evaluation of available literature. METHODS Relevant questions were distributed among the experts, who generated draft statements for consideration by the entire panel. A modified(More)
OBJECTIVE Data to support treatment algorithms in ambulatory paediatric UC are scarce. We aimed to explore the 1 year outcome in an inception cohort of paediatric UC patients and to identify early predictors of good outcome that might serve as short term treatment targets. DESIGN A chart review of 115 children with new onset UC was performed (age 11 ± 4.1(More)
