[Respiratory complications of leptospirosis. Apropos of 6 cases, 3 of which show hemodynamic studies]. / Complications respiratoires des leptospiroses. A propos de 6 cas dont trois avec étude hémodynamique.

Six cases of leptospirosis with pulmonary complications are reported. Three cases were accompanying an hepato-nephritis due to L. icterohaemorrhagiae. The first patient died with massive hemoptysis. The second, presenting a bilateral pneumopathy predominant on the left side, recovered after plasma exchange and hemofiltration. The third case concerned a pulmonary edema complicating a vascular refilling in a shock syndrome it simply recovered. The three other cases were observed in an anicteric leptospirosis: in two cases, L. Australis was responsible; in the last, L. icterohaemorrhagiae was involved. The first patient had a radiologic picture simulating miliary tuberculosis. The second had pulmonary edema complicating a vascular refilling in a shock syndrome. The last was an acute respiratory distress syndrome, treated with artificial ventilation with penicillin therapy and corticotherapy. All these 3 patients recovered. The diagnostic, physiopathologic and therapeutic problems of these pulmonary complications of leptospirosis are discussed. The lesional nature of the pulmonary edema is proved by the low pulmonary wedge pressures observed with the Swan-Ganz Catheter.

[Unusual cause of digestive hemorrhage in chronic hemodialysis patients: splenic aneurysm with arteriovenous fistula]. / Une cause exceptionnelle d'hémorragies digestives chez l'hémodialysé chronique: l'anévrysme splénique, avec communication artério-veineuse.

A 45 years old woman, hemodialysed since 1981, with an history of Staphylococcal septicemia in may 1983, is admitted in emergency room in may 1984 for massive gastro intestinal bleeding. After oesogastro fibroscopy suspecting duodenal ulcer, because continuous and recurrent bleeding, a laparotomy find only symptoms of portal hypertension (ascites, venous dilatation on abdominal oesophagus and stomach). The ligation of this venous dilatations stop temporarily the gastro intestinal bleeding. But recurrence of this bleeding conduct to a celiac angiography discovering a splenic aneurysm with arterio venous fistula. The surgical treatment of this aneurysm can stop the gastro intestinal bleeding. Histopathologic observation of this aneurysm can suspect an infectious origin.
