[Primary and idiopathic hyperaldosteronism. Course 1 year after operation. Apropos of 28 cases].

The course of mean arterial pressure was compared in two series concerning 18 primary or tumoral hyperaldosteronism and 8 idiopathic ones. Identification of the nature of the hyperaldosteronism should not yet motivate a decision on principle, surgical in case of tumor, medical in an idiopathic case. In the latter case cooperation and tolerance of medical treatment, severity of hypertension also come into consideration. A positive spirolactone test, a hypertension course of less than six years were in our experience a good indication of successful surgery, as opposed to a normal unilateral renal biopsy. In case of operation, the removal protocol should adapt to the peroperative findings; 80% adrenalectomy is the most common procedure, except in the case of isolated adenoma of more than 10 mm diameter.

[Treatment of deep venous thrombosis. Comparative study of a low molecular weight heparin fragment (Fragmin) by the subcutaneous route and standard heparin by the continuous intravenous route. A multicenter study].

This open, randomised multicenter trial compares the efficacy and safety of Fragmin administered subcutaneously twice daily with standard heparin administered by continuous infusion in the treatment of deep vein thrombosis (DVT). The initial dose of Fragmin is 100 U anti-Xa/kg/12 h and the further doses are adjusted according to the anti-Xa activity between 0.5 and 0.8 U/ml, 3 hours after the morning injection. The initial dose of standard heparin is 240 UI/kg/12 h. The dose adjustments are based on the daily results of APTT (1.5 - 3 times the control). Treatments efficacy are appreciated when comparing the venography performed before and after 10 days of treatment. The safety is evaluated on clinical parameters and iterative biological tests. Sixty-six patients have been included in this study. Efficacy of the two treatments is equivalent with a phlebographic improvement in respectively 79.3 p. 100 (Heparin Group) and 71.0 p. 100 (Fragmin Group) of the cases and an aggravation in 3.4 p. 100 and 6.4 p. 100 (NS) respectively. The frequency of dosage adjustments is lower and the stability of biological tests is better in the Fragmin group. In conclusion, the administration of Fragmin twice daily by subcutaneous route seems to be equivalent at least to standard heparin continuous infusion in the treatment of recent DVT. The better convenience and safety of Fragmin have to be verified on a larger panel of patients.
