title: [The etiological and pathogenetic characteristics of duodenal peptic ulcer in adolescents].
abstract: Studied by endoscopy were 100 adolescents with diagnosed duodenal ulcer, as were 100 essentially healthy subjects and 90 ones of the same age presenting with primary chronic gastroduodenitis together with 60 adults who had duodenal ulcer. The following items were etiologic risk factors for duodenal ulcer, if combined, in the above adolescent series: Frequent episodes nervous of tension, hereditary predisposition and helicobacteriosis. In juveniles with duodenal ulcer, secretion and motility of the stomach appeared to be subjected to changes to a higher degree than it was in adult subjects with duodenal ulcer, while functions of the psychovegetative and immune systems were found to be less changeable in the former. In adolescents presenting with duodenal ulcer and primary chronic gastroduodenitis, the etiologic risk factors and pathogenetic changes were found out to be identical.
