Reversal of acute renal failure following percutaneous transluminal recanalization of an atherosclerotic renal artery occlusion.

Thrombosis of the renal artery to a single functioning kidney is a known cause of anuric acute renal failure in atherosclerotic hypertensive patients. In the present report, recovery of renal function rapidly occurred following transluminal recanalization of the occluded artery with a 7F catheter after a 5-week period of anuria. The most interesting feature was that improvement of renal artery permeability was observed following a minimal interventional procedure.

[24 hour polygraphic study of the waking-up and falling asleep periods in patients with hepatic encephalopathy (author's transl)].

24 h sleep-waking EEG records of 23 patients with hepatic cirrhosis, 18 having hepatic encephalopathy, were studied. Comparison with a group of normal controls showed an increase in diurnal somnolence (08 h-22 h) and nocturnal waking (22 h-08 h) in all the patients. There was a significant reduction in the longest duration of waking and uninterrupted sleep periods in the patients with cirrhosis. Triphasic waves (characteristic of hepatic encephalopathy) were usually increased during waking and reduced in sleep. The factors involved in this disturbance of sleep-waking patterns in hepatic encephalopathy are discussed (cerebral monoamines, false neurotransmitters, cerebral arteriovenous shunts...).
