[Exogenous and endogenous gastric secretion in children with primary duodenal ulcer].
Twelve cases of duodenal ulcer were studied in children, 11 male and 1 female (mean age 10 +/- 2.7 years) (mean weight 30 +/- 3.7 Kg.) (Group 1). All were submitted to x-ray examination and/or digestive endoscopy. Twenty healty children, matched by weight, age and sex were chosen as controls (Group 2). All children underwent a standardizet protein meal to evaluate serum gastrin and pepsinogen I response and the pentagastrin test for gastric acid secretion. The serum gastrin levels were found to be without significative differences in the two groups, both in the fasting state (Group 1: 77 +/- 16 pg/ml vs. Group 2: 58 +/- 12 pg/ml) and after food stimulation (Group 1: 110 +/- 22 pg/ml vs. Group 2: 88 +/- 47 pg/ml), whereas the basal serum pepsinogen I (Group 1: 74 +/- 10 ng/ml vs. Group 2: 43 +/- 1.8 ng/ml) and after meal (Group 1: 83 +/- 14 ng/ml vs. Group 2: 49 +/- 2.1 ng/ml) values were statistically higher in the duodenal ulcer group (p less than 0.01). The pentagastrin test showed a statistically difference in MAO (Group 1: 0.370 +/- 0.10 mmol/H+/hr./Kg. vs. Group 2: 0.210 +/- 0.11 mmol/H+/hr./Kg. - p less than 0.001) and PAO (Group 1: 0.480 +/- 0.13 mmol/H+/hr./Kg. vs. Group 2: 0.351 +/- 0.12 mmol/H+/hr./Kg. - p less than 0.005) between the groups. The results confirm that elevated gastric acid response is already present in duodenal ulcer of children and seems to be its cause rather than its consequence. Our finding of an already reported family histories of the disease, further support an inherited basis for duodenal ulcer in children.

[Usefulness of abdominal echography in the diagnosis of active Crohn's disease].
OBJECTIVE: The aim of this study was to evaluate the relevance of the ultrasonography in assessing activity in a series of patients with Crohn's disease. PATIENTS AND METHODS: A series of 24 patients with active (Crohn's disease activity index > 150) ileal or ileocolonic Crohn disease underwent abdominal ultrasonography. RESULTS: There was a significant correlation between bowel wall thickening and the Crohn's disease activity index: the higher the bowel wall thickening was the higher were the values of Crohn's disease activity index. Two or more ultrasound studies were performed in 10 patients with bowel wall > 4 mm during treatment, and a progressive normalization of bowel wall size was observed with new thickening when recurrence occurred. CONCLUSIONS: A bowel wall thickening (> or = 4 mm) was found in patients with active Crohn's disease. A patient with bowel wall thickness > 6 mm should make us suspect the presence of stenosis. Abdominal ultrasonography is an accurate method in the first assessment of Crohn's disease because its high correlation with the Crohn's disease activity index.
