Twenty five per cent of inflammatory bowel disease presents in childhood. Growth and nutrition are key issues in the management with the aim of treatment being to induce and then maintain disease remission with minimal side effects. Only 25% of Crohn's disease presents with the classic triad of abdominal pain, weight loss, and diarrhoea. Most children with ulcerative colitis have blood in the stool at presentation. Inflammatory markers are usually although not invariably raised at presentation (particularly in Crohn's disease). Full investigation includes upper gastrointestinal endoscopy and ileocolonoscopy. Treatment requires multidisciplinary input as part of a clinical network led by a paediatrician with special expertise in the management of the condition.
In this study no difference in alpha-defensin expression was found in the TI of CD children and controls. However, significant reduction of Tcf-4 in L1+L3 phenotype suggests that a possibly impaired PC differentiation may lead to altered HD5 and HD6 expression at some stage of disease. Additionally, substantially increased expression of alpha-defensins in the inflamed colonic mucosa of children with IBD raises the question for their potential involvement in modulating inflammation in these patients.
This study prospectively compared the rates of skill acquisition in ileocolonoscopy in 2 consecutive groups of trainees in paediatric gastroenterology, with 1 cohort exposed to virtual endoscopy. All paediatric gastroenterology trainees rotating through our department during a 7-year period between 1997 and 2004 were formally assessed while performing ileocolonoscopies using a trainer case-by-case method. Fourteen consecutive trainees with no previous experience of ileocolonoscopy were assessed. Comparison of rates of skill acquisition and lesion recognition using multiple linear regressions revealed a significant acceleration of achievement of endoscopic goals (P < 0.0001) in the group with prior exposure to virtual endoscopy.
This study suggests that an adult colorectal surgeon can provide a safe and effective service for adolescents with IBD, including the provision of laparoscopic resection in this challenging patient group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
