[Fibrous inflammatory polyp of the digestive tract. Apropos of 5 cases].

Inflammatory fibroid polyp is a rare benign tumor of the digestive tract. The authors report three cases: two intestinal and one gastric. These cases are of particular interest because of the association ill one case of an intestinal submucosal lipoma with the inflammatory fibroid polyp, and the existence in the gastric case of an inflammatory reaction caused by food debris. This offers, further evidence in support of the theory implicating a chronic inflammatory reaction.

[Collagenous enterocolitis. Apropos of a case and review of the literature].

Collagenous enterocolitis is a recent entity of which only two cases have been published. The authors report the association of collagenous colitis and collagenous sprue in a 67-year-old woman. The diagnosis of collagenous enterocolitis is based on the presence of a duodenal collagen deposit with partial villous atrophy associated with collagenous colitis. The symptom appeared one month after non-steroidal antiinflammatory treatment. The authors discuss the role of drug toxicity in the pathogenesis of collagenous enterocolitis.

[Malignant lymphoma on a gastric stump].

We report a case of lymphoplasmocytic and immunoblastic gastric remnant lymphoma occurring in a 51 year-old male. This patient had undergone subtotal gastrectomy for a gastric peptic ulcer at age 37. Histologic findings in the initial gastric specimen showed a dense lymphoid infiltrate surrounding the ulcer within the gastric mucosa. This proliferation was grouped into distinct follicles, and was compatible with pseudo-lymphoma. The progression of pseudo-lymphoma to malignant lymphoma is suggested.

[Study of malabsorption of lactose by the hydrogen breath test in a population of 70 Tunisian adults].

Lactose malabsorption was studied by the hydrogen breath-test in 23 adults suffering from irritable bowel syndrome (group A) and in 47 healthy subjects (group B). The concentration of hydrogen in end-expired alveolar samples was measured after ingestion of 25 g of lactose. Among the 70 subjects, 6 (8.5 p. 100) were not hydrogen producers and were excluded from the study. Lactose malabsorption was shown in 51 of the remaining 64 subjects (79.6 p. 100). Among these 51 patients, 36 were healthy and 15 had an irritable bowel syndrome. The frequency of lactose malabsorption among the 43 healthy hydrogen producers was 83 p. 100. This value is similar to those observed in other studies (greek and italian). Our results suggest that lactose malabsorption is frequent among the tunisian adult population.
