Celiac disease presenting with microcephaly.

A 15-month-old girl with celiac disease presented with microcephaly and developmental delay. Head growth resumed during a gluten-free diet. Subsequent gluten ingestion resulted in no head growth, areflexia, and increased celiac antibodies. All resolved with gluten elimination. Poor head growth may precede other clinical manifestations of celiac disease.

Laparoscopy in the management of children with chronic recurrent abdominal pain.

BACKGROUND AND OBJECTIVES: The purpose of the present study was to evaluate the results of diagnostic laparoscopy in children with chronic recurrent abdominal pain. PATIENTS AND METHODS: Thirteen children with chronic recurrent abdominal pain were subjected to diagnostic laparoscopy. Ages varied from 10 to 17 years. There were six males and seven females. Abdominal pain was present from 3 weeks to 12 months (mean, 2 months). Extensive laboratory and imaging studies did not contribute to the diagnosis. In all patients, the pain was disabling and severe enough to warrant repeated visits to the pediatrician, emergency room visits, or hospital admissions, as well as absence from school. RESULTS: All children recovered uneventfully. Laparoscopic findings that identified the cause of abdominal pain were obtained in 12 of 13 patients. Laparoscopic appendectomy was done in all patients. There were no operative complications. One child presented three months later with incomplete small bowel obstruction, which resolved with conservative management. There were no other postoperative complications. Follow-up varied from six months to three years. Abdominal pain resolved in ten patients. One patient presented eight months later with biliary dyskinesia. She improved following laparoscopic cholecystectomy and later on sphincterotomy, but her pain has not yet completely resolved. One patient presented six months later with abdominal pain secondary to intestinal adhesions. Her pain completely resolved after laparoscopic lysis of adhesions. A third patient who developed lower abdominal pain six months after laparoscopy improved with conservative management and antibiotics for pelvic inflammatory disease. CONCLUSIONS: Diagnostic laparoscopy is a valuable procedure in the management of children with chronic recurrent abdominal pain. In the present study, laparoscopic examination revealed the cause of abdominal pain in most patients, and this pain resolved in most cases. Based on our experience, we recommend diagnostic laparoscopy early in the course of debilitating chronic recurrent abdominal pain in children. Appendectomy should be done when no other significant cause of abdominal pain has been identified, even if the appendix looks normal.

Nonspecific esophageal motility disorders in children without gastroesophageal reflux.

BACKGROUND: Nonspecific esophageal motility disorders (NEMDs) have been identified in up to 50% of adults with noncardiac chest pain or dysphagia. This study sought to determine the incidence of NEMDs in children with upper gastrointestinal tract symptoms and to evaluate the clinical course of pediatric patients with these manometric abnormalities. METHODS: The study involved 154 children aged 4 to 18 years (mean age, 11.6+/-2.6 years [SE]) who had upper gastrointestinal, swallowing-related symptoms. The children were evaluated by 24-hour intraesophageal pH monitoring, esophageal manometry, and esophagogastroduodenoscopy. RESULTS: Gastroesophageal reflux (GER) was diagnosed by pH study in 109 (71%) of 154 patients, and examination of biopsy specimens demonstrated esophagitis in 70 children with GER. Results of esophageal manometry were abnormal in 30 (67%) of 45 children without GER. A variety of motility disorders were diagnosed in 17 of the patients without GER, whereas NEMDs were diagnosed in the remaining 13 children (mean age, 10.6+/-2.7 years; 10 boys, 3 girls). Patients with GER showed normal esophageal wave propagation; however, mean lower esophageal sphincter pressure was significantly lower in patients with GER than in children with NEMDs. The children with NEMDs exhibited a diverse array of symptoms, including esophageal food impaction in 4 of the 13 patients. During a 36.2+/-4.3-month follow-up period, no correlation was found between therapeutic intervention and clinical course in the 13 patients with NEMDs. Symptomatic improvement occurred in 6 of 13 patients, including 3 children for whom no pharmacologic therapy was prescribed. CONCLUSIONS: These data indicate that NEMDs represent a common group of esophageal manometric abnormalities in children with upper gastrointestinal tract symptoms and without GER. Food impaction appears to be a relatively frequent complication, and NEMDs should be considered in children who have this finding.

Treatment of Helicobacter pylori-associated gastroduodenal disease in children. Clinical evaluation of antisecretory vs antibacterial therapy.

The charts of 54 children diagnosed with antral H. pylori were reviewed, to establish the incidence of gastroduodenal inflammation and compare therapeutic efficacies of antisecretory vs. antibacterial therapy. Histology demonstrated normal mucosa in three cases (6%) and gastric/duodenal inflammation (> or = Whitehead grade 3) in 51 biopsies (94%). 23/43 children (53%) initially responded to H2-blockers; however, by 10 mo, 13 had relapsed clinically. All of these patients subsequently responded to amoxicillin plus bismuth subsalicylate. Of the 20 children who failed to enter remission after an initial course of H2-blockers, all became symptom-free after treatment with amoxicillin/bismuth. Compared to antisecretory agents, antibacterial treatment induced clinical remission in 11/11 patients (p < 0.001), who remained symptom-free for 10 +/- 0.2 mo. Clinical remissions were maintained in significantly more patients following amoxicillin/bismuth vs. H2-blockers (44/54 vs. 10/43 courses, p < 0.001); and, the cumulative probability of remaining asymptomatic was significantly greater in the antibiotic group (p < 0.001). These data suggest that gastric colonization by H. pylori is highly predictive of mucosal pathology in children. Initial therapy should be directed toward achieving bacterial eradication, as opposed to gastric acid suppression.

Helicobacter pylori-related gastroduodenal disease in children. Diagnostic utility of enzyme-linked immunosorbent assay.

To evaluate the accuracy of IgG and IgA serological tests in establishing a diagnosis of Helicobacter (Campylobacter) pylori gastric infection, 60 children presenting with chronic abdominal pain were prospectively studied. Endoscopic antral biopsies were obtained and analyzed for the presence of H. pylori using three standard methods: culture and identification of bacterial isolates, microscopic examination for morphologically characteristic bacteria, and urease production by the biopsy specimen. Concomitantly obtained serum samples were analyzed for the presence of IgG and IgA antibodies against H. pylori surface antigens using enzyme-linked immunosorbent assay (ELISA). Thirty-four of 60 (56.6%) had histological evidence of chronic active gastritis, eight of whom (13.3%) also had evidence of H. pylori infection by at least one criteria. Six of the eight infected patients had H. pylori demonstrated by all three methods. Of the eight infected patients, seven had IgG antibodies against H. pylori (sensitivity of 87%) and six had IgA antibodies (sensitivity of 75%). Among the six patients who had H. pylori infection confirmed by all three methods, all had IgG antibodies (sensitivity of 100%). In the patients without evidence of H. pylori infection, the IgG ELISA had a specificity of 96% (50/52), and the IgA ELISA had a specificity of 100% (52/52). Our data suggest that serological testing for the presence of antibodies against H. pylori may be a useful diagnostic tool in screening children with chronic abdominal pain for the presence of gastric infection with H. pylori.
