Electrophysiological effects and mechanism of action of oral quinidine in patients with sinus bradycardia and first degree A-V nodal block.

The effects of quinidine on sinus nodal and A-V nodal function were assessed in 20 patients (age: 60 +/- 7 years) with sinus bradycardia and a prolonged A-H interval. Electrophysiological studies were performed twice in each patient. In the first study, the measurements of sinus and A-V node function were evaluated both in the basal state and after autonomic blockade (propranolol 0.

[Monitoring of high-risk pregnancies (author's transl)].

The AA. have monitored 202 patients affected by several pathological conditions and at different stages of their pregnancies. Among them, 173 were pregnancies without complications.

[Rate meaning of estriol-dosage in the pregnant wife pointing out the phoetus development (author's transl)].

The AA. point out the meaning of the urinary estriol dosage in high risk pregnancy. The screening must be frequent and regular, with constant growing curve all time along.

[New views referred to gamma-glutamyl-transpeptidase (author's transl].

The AA. have observed some patients suffering from persistent chronic hepatitis, aggressive chronic hepatitis, severe virus hepatitis, hepatic cirrhosis, hepatic metastasis, cholecystolithiasis, hepatic abscess, congestic heart disorder, alcoholism also patients treated with barbiturics and benzodiazepine, comparising in the meanwhile gamma-glutamyl-transaminase. They would suggest a new interpretation: the observed enzyme was higher in the obstructive diseases, gamma-GT also notable higher in the cellular hepatic diseases (hepatitis, cirrhosis and so on).

[Treatment of obesity with chorionic gonadotropins. Relations between obesity, dyslipidemia and arthero-arteriosclerosis].

A long account of the many factors responsible form atherosclerosis (dysmetabolism, physical, genetic and familial factors, immunobiological features, diet) is followed by an assessment of obesity as a main risk factor in the local pathology of atherosclerosis. Results obtained in the treatment of obesity with chorionic gonadotropin and a 500 calorie standard diet are presented. These were highly satisfactory with respect to weight loss, tolerance, and marked improvement (or even normalisation) of blood lipid values, which were initially pathological in many cases.

[Hepato-Quick: a new diagnostic test for liver diseases (author's transl)].

The AA. have adopted usual biohumoral examinations and the Hepato-Quick test for a group of patients affected by various liver diseases. Hepato-Quick contains thromboplastine from monkey brain and plasma absorbed on barium sulphate.
