[Spontaneous renal allograft rupture. Diagnosis and treatment. Report on five cases (author's transl)].

The authors describe five cases of renal allograft rupture as a result of acute rejection. In one case of perineal hematoma, no operation was performed. The evolution of the hematoma led to a periureteral sclerosis, which was successfully operated.

Structural and ultrastructural peritoneal membrane changes and permeability alterations during continuous ambulatory peritoneal dialysis.

Normal and abnormal structure of the peritoneum is described in biopsies obtained from 15 cadavers and 13 patients on continuous ambulatory peritoneal dialysis (CAPD) at the onset of their treatment and after several months. In a few patients a loss of ultrafiltration due to a higher permeability of the peritoneum for glucose was observed. This hyperpermeability seems to be due to a patchy or total destruction of the mesothelium; it seems also to be dependent upon the thickness of the fibrous band separating capillaries from the peritoneal cavity.

[The resistance to infection of digestive sutures. Experimental study (author's transl)].

The authors study the effects of severe sepsis due to pathogenic gems in large quantity an healing of the suture of the ileum in the rabbit. Contamination of the suture did not lead to any breakdown of the suture whatever the germ. These experimental facts, compared with the data in the literature suggest that the peritoneal serosa ensures efficacious anti-infectious defence, permitting healing of intra-peritoneal digestive sutures in spite of the septic nature of the intestinal contents.
