title: [Monthly and seasonal distribution of gastric and duodenal ulcer in an endoscopy study group].
abstract: The question of a monthly and seasonal dependence of the gastroduodenal ulcers was attended to. The gastroscopic reports of a period of 5 years were evaluated. Here, 2,497 florid ulcers were found, 1,114 in the stomach (= 10.4%) and 1,383 in the duodenum (= 13.2%). Neither monthly nor seasonally an accumulation could be established. On the contrary a nearly regular distribution was found, so that in accordance with other authors a seasonal dependence of the ulcerous disease cannot be derived.
