Congenital chloride diarrhea presenting in newborn as a rare cause of meconium ileus.

Postpartum abdominal distention and meconium ileus may occur due to intestinal obstruction, Hirschprung disease or cystic fibrosis. However, other rare and challenging etiologies such as congenital chloride diarrhea (CCD) should be included in differential diagnosis of such presentation. We present a premature baby girl who had distended abdomen and lack of meconium immediately after birth. Surgical etiology was excluded and she was mistakenly suspected of having cystic fibrosis due to meconium ileus. CCD was diagnosed by recognition of watery diarrhea in association with hyponatremic, hypochloremic metabolic acidosis. Mutation analysis confirmed the diagnosis.

Evidence-based recommendations for bowel cleansing before colonoscopy in children: a report from a national working group.

BACKGROUND: There are no current recommendations for bowel cleansing before colonoscopy in children. The Israeli Society of Pediatric Gastroenterology and Nutrition (ISPGAN) established an iterative working group to formulate evidence-based guidelines for bowel cleansing in children prior to colonoscopy. METHOD: Data were collected by systematic review of the literature and via a national-based survey of all endoscopy units in Israel. Based on the strength of evidence, the Committee reached consensus on six recommended protocols in children. Guidelines were finalized after an open audit of ISPGAN members. RESULTS: Data on 900 colonoscopies per year were accrued, which represents all annual pediatric colonoscopies performed in Israel. Based on the literature review, the national survey, and the open audit, several age-stratified pediatric cleansing protocols were proposed: two PEG-ELS protocols (polyethylene-glycol with electrolyte solution); Picolax-based protocol (sodium picosulphate with magnesium citrate); sodium phosphate protocol (only in children over the age of 12 years who are at low risk for renal damage); stimulant laxative-based protocol (e. g. bisacodyl); and a PEG 3350-based protocol. A population-based analysis estimated that the acute toxicity rate of oral sodium phosphate is at most 3/7320 colonoscopies (0.041 %). Recommendations on diet and enema use are provided in relation to each proposed protocol. CONCLUSION: There is no ideal bowel cleansing regimen and, thus, various protocols are in use. We propose several evidence-based protocols to optimize bowel cleansing in children prior to colonoscopy and minimize adverse events.

Efficacy of bismuth-based triple therapy in children with abdominal pain and Helicobacter pylori gastritis.

BACKGROUND: To evaluate the effect of a therapeutic regimen of 7 days versus 14 days on the clinical manifestations of Helicobacter pylori gastritis in children. METHODS: Ninety children (age 2-19 years) who had abdominal pain and/or recurrent vomiting were determined to have H. pylori gastritis by endoscopy, histology, and a Giemsa stain positive for H. pylori. The patients were randomized to receive amoxicillin, metronidazole, and bismuth subcitrate for 7 days (group A; 45 children) or 14 days (group B; 45 children) and were observed clinically for 19 +/- 11.5 months. Resolution of all abdominal and gastrointestinal symptoms was considered a good response. RESULTS: A good response was obtained in 36 (80%) children from group A, and in 37 (82%) from group B. A recurrence of symptoms occurred in four (11%) of the responders from group A, and in six (15.2%) from group B. CONCLUSIONS: A 7-day course of bismuth-based triple therapy for H. pylori gastritis in children appears to be clinically as effective as a 14-day regimen. The feasibility of a shorter therapeutic regimen may enhance patient compliance and provide a better chance of clinical benefit.
