The hemolytic-uremic syndrome consists of hemolytic anemia, renal failure, and thrombocytopenia. Submucosal hemorrhage with "thumbprinting" on roentgenographic examination of the colon with barium was demonstrated in four patients, prolapse of the rectum in two patients, and pseudomembranous enterocolitis and toxic megacolon in one. These lesions are not generally associated with hemolytic-uremic syndrome. The presence of these lesions in a child with bloody diarrhea should suggest hemolytic-uremic syndrome as a possible diagnosis. Sigmoidoscopy and roentgenographic examination of the colon with barium should be done in selected patients with hemolytic-uremic syndrome to evaluate the degree of colonic involvement and the need for surgery.

A young man in Germany was bitten by a large captive saw-scaled viper (Echis 'pyramidum'-complex) of Tunisian origin. During the first few hours after the bite he developed evidence of disseminated intravascular coagulation and fibrinolysis, and bled spontaneously. Despite being given a total of 310 ml of three different Echis-specific antivenoms (together with large amounts of fresh frozen plasma and concentrated clotting factors), venom antigenaemia (measured by enzyme immunoassay) and coagulopathy persisted for more than 10 days, and he developed a haemolytic anaemia and mild renal dysfunction. Transient bilateral ptosis was attributed to envenoming. The venom of the snake responsible for the bite was immunologically distinct from that of Nigerian E. ocellatus and was clearly not neutralised by the three monospecific antivenoms which had been administered. This case is another illustration of the geographical variation in snake venoms and the need for pooling venoms from snakes from different parts of the geographical range in the preparation of antivenoms. Envenoming by North African Echis species may not be reversible by available antivenoms.

A 49-year-old woman who underwent mitral valve replacement with 29 mm Mitroflow pericardial valve in 1985 started to have severe hematuria, anemia and icterus around May 1994. She was diagnosed to have mitral regurgitation with hemolytic anemia due to structural deterioration of the prosthetic valve. She underwent replacement of the prosthetic valve with 29 mm St. Jude medical mechanical valve, which alleviated the symptoms remarkably. The explanted valve showed an extensive cuspal tear and prolapse close to the commissure and poor endothelialization of the inflow surface of the frame. In our experience the rate of structural deterioration of the Mitroflow valve is so high that we discontinued using this bioprosthesis.

Hemolytic anemia is a well-recognized complication of mechanical heart valve prosthesis but, as yet, has not been reported after mitral valve repair with chordal replacement. We report a case of severe hemolytic anemia after mitral valve repair with chordal replacement and Carpentier-Edwards annuloplasty ring insertion. Progressive prolapse of the anterior leaflet due to the artificial chordae being too long caused recurrent regurgitation which was responsible for the hemolysis. The patient also had idiopathic thrombocytopenic purpura, but successful second mitral valve repair was performed after high-dose gamma-globulin therapy.
