[Incidence of duodenal ulcer in the city of Reims 1988].

No epidemiological data on the incidence of duodenal ulcer are available for a well-defined population in France. We therefore conducted a prospective study in the urban population of Reims. All radiologists, gastroenterologists and surgeons of this town were asked to report all new cases of duodenal ulcer seen during one year.

Lymphoid follicular proctitis. A condition different from ulcerative proctitis?

A heterogeneous group is formed by patients presenting with clinical features suggestive of inflammatory bowel disease limited to the rectum and whose rectal biopsies show lymphoid follicular hyperplasia of the mucosa. All these cases are traditionally considered as one variant of chronic ulcerative colitis, so-called ulcerative proctitis. Twenty such cases were critically assessed on clinical, endoscopic, and histologic grounds, as well as on response to treatment and follow-up data.

Incomplete sulphomucin-secreting intestinal metaplasia for gastric cancer. Preliminary data from a prospective study from three centres.

A joint prospective long term study of gastric biopsies has been undertaken to survey intestinal metaplasia Types I, II, and III in terms of their incidence, distribution and value in the selection of high risk cancer patients. This study is based on protocols agreed between three centres for endoscopy, histological interpretation, and mucin histochemistry. The results on the first 1350 gastric biopsies examined during 1981-1982 are presented.
