[Chronic gastritis caused by Ollulanus tricuspis (Leuckart, 1865) in a tiger].

Abstract: A chronic gastritis caused by an infestation with O. tricuspis is described. The differential-diagnostic importance of this parasitosis in chronic maldigestive diseases is emphasized. Conventional coproscopic diagnostic procedures fail as the life cycle of the parasite is confined to the gastrum of the host.

Chronic gastritis and peptic ulcer.

Abstract: The relationship between chronic gastritis and peptic ulcer was studied in 97 patients, 51 with duodenal ulcer and 46 with gastric ulcer. Six biopsies (three from the antrum and three from the body) were obtained under direct vision by means of an Olympus panendoscope. Chronic gastritis was classified according to the grade of inflammation (slight or moderate and intense), and to its location (antritis or pangastritis). In gastric ulcer the relationship between frequency of chronic gastritis and the site of the ulcer (antrapyloric, at the angulus, body of the stomach) was also established. Antritis was just as frequently observed in duodenal ulcer (94%) as in gastric patients (96%), but severe inflammation of the antrum was higher in G.U. (43%) than in D.U. (17%). Chronic gastritis of the gastric body was always accompanied by antritis, both in G.U. and in D.U. and was observed in 63% of the former group and 37% of the latter. Severe inflammation of the glandular portion of the stomach occurred in only one patient with D.U (2%) and in 7 with G. U (15%). In the present investigation, no relationship between between the site of gastric ulcer and the frequency of chronic gastritis was observed.

[Epidemiology of gastric cancer. 2nd communication (author's transl)].

Abstract: Of 257 patients with gastric cancer and of 766 persons with different stages of chronic gastritis or normal gastric mucosa, 35 items from epidemiologic studies were used for this analysis. The comparison of epidemiology of chronic gastritis with epidemiology of stomach cancer by univariate and multivariate variance analysis shows numerous common variables (social group; digestive diseases). Furthermore gastric cancer is characterized by variables which give hints to cancerogenous noxes. Gastric cancer patients are distinguished from persons with atrophic gastritis by the following variables: cancerogenes; social class; genetic factors, and digestive diseases. It is suggested that these factors are relevant for stomach cancerogenesis in atrophic gastritis.
