[Proctocolitis caused by Schistosoma mansoni in AIDS. A clinical and immunohistochemical study of a case].

An imported case of intestinal schistosomiasis in AIDS is analysed by the relationships between immune response, diagnostic methods, pathogenetic mechanisms. The inconclusiveness of negative results from both serology and stool parasitology is remarked whereas the efficacy of associated histological, histochemical and immunohistochemical methods is emphasized in order to get better data on aetiological diagnosis and on cell types and size of reactive granulomas. In the case studied, negative serology, absent fecal egg excretion and uneffective granulomatous response with scarcity of T and B lymphocytes have been documented by means of the above methods.

[Colonic mucins in idiopathic proctocolitis and Crohn's disease].

The AA. examine 75 cases of Crohn disease for studying the secretion of mucina in the different stages of disease. The result is that the acute stage is marked by a strong depletion of mucina; the interesting part of this work is that the study of sulpherized acid mucinae is an excellent standard of diagnosis in regard to the benign evolution of this disease.
