[Midpoint follow-up results of aortic valve replacement with the Ionescu-Shiley pericardial bioprosthesis. Apropos of 109 patients].

Between March 1980 and May 1985, 109 adults with an average age of 59 years underwent aortic valve replacement with a pericardial Ionescu-Shiley xenograft. Twenty six of the prostheses were of small size (N 19 and 21). In 20 patients, the operation was associated with another procedure (15 aorto coronary bypass grafts and 5 conservative mitral valve procedures). Before surgery, 73.4% of patients were in functional Stages III or IV, and 9.2% had permanent or paroxysmal atrial fibrillation. The average follow-up period was 24 months (4 to 59). The operative mortality was 5.5%. The 4 year actuarial survival rate was 86% with 82% good functional results. At the same date, 96.4% of patients had not developed endocarditis, 96% had not been reoperated and 93.8% had no prosthetic valve dysfunction. No cases of primary degeneration were observed but a diastolic murmur without any haemodynamic consequences was detected in 20% of patients at 4 years. Seventy four per cent of subjects were not anticoagulated at 1 year and 85% were without anticoagulants after one year. Only one haemorrhagic complication was noted (0.46% patient/years). There were no cases of occlusive thrombosis; the incidence of thromboembolism was 3.7% patient/years in aortic without mitral valve disease, irrespective of the cardiac rhythm and 2.7% patient/years in patients in sinus rhythm. In this subgroup, 88% had not had any thrombo-embolic complication despite the absence of anticoagulants at 4 years. An Indium III labelled platelet scan was positive in 2 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cutaneous leishmaniasis in northern Algeria].

A resurgence of cutaneous leishmaniasis is presently noted in northern Algeria. This form of oriental sore is caused by a parasite belonging to the Leishmania donovani complex. Its epidemiological and clinical characteristics allow distinction with the L. major zoonotic cutaneous leishmaniasis known to occur in the steppe regions of Algeria. Preliminary results of a clinical trial involving the use of ketoconazole, indicate that this drug is rapidly effective.

[Hydrogen peroxide in the surgery of hydatid cyst].

Discouraged by the dangers and drawbacks of the usual scolicidal agents (formalin or strongly hypertonic saline), the authors have tried and adopted hydrogen peroxide in surgery of hydatid cysts. Liberal applications of this product on the operative field seem to be devoid of harmful effects. This, together with constant and rapid effectiveness, easy handling, low cost and wide availability should recommend hydrogen peroxide as the sole scolicidal agent in general surgery units.
