[Congenital factor XII deficiency: a rare cause of increased activated cephalin time].

The fortuitous detection of an increased activated cephalin clotting time is often dependent on defects of the blood-clotting factors synthesized by the liver, haemophilia or von Willebrand's disease, circulating anticoagulants or specific deficiencies of various factors necessary for blood-clotting mechanisms. Much more rarely, it may be due to an isolated Hageman factor defect. This deficiency does not lead to an increased bleeding tendency and surgery has proved surprisingly uneventful.

[Atracurium and cirrhosis: clinical study of the curariform action].

Hepatic function influences the action of muscle relaxants. Among these drugs, the elimination of atracurium does not depend on liver function. The clinical effects of atracurium were studied in ten patients with portal hypertension and some degree of liver dysfunction and in ten normal patients.
