Ancient remedies revisited: does Allium sativum (garlic) palliate the hepatopulmonary syndrome?

Hypoxia in the setting of liver disease is often multifactorial. Obstructive or restrictive lung disease, pleural effusions, and tense ascites are common underlying disorders. Less often observed and frequently unrecognized is hypoxia related to diffuse intrapulmonary shunting--the hepatopulmonary syndrome.

Laser catheter-induced atrioventricular nodal delays and atrioventricular block in dogs: acute and chronic observations.

Selective modification of atrioventricular (AV) nodal conduction, that is, induction of varying degrees of AV nodal delays or block (second or third degree), or both, was achieved with a pervenous laser catheter technique. In six adult mongrel dogs anesthetized with pentobarbital (Nembutal), 5F leads were placed through femoral and external jugular veins and placed into the right atrium and His bundle region. Through another femoral vein, a 200 micron optical fiber was inserted by way of a 7F catheter with a preformed curved tip.

Microtransection of the His bundle with laser radiation through a pervenous catheter: correlation of histologic and electrophysiologic data.

This study describes microtransection of the His bundle with a pervenous laser catheter in a live dog. In an adult mongrel dog anesthetized with Nembutol , administered intravenously, electrode catheters (No. 5Fr and 6Fr ) were inserted through a femoral vein and positioned in the high right atrium for atrial pacing and in the His bundle region for recording of His bundle electrograms.

[Value of provocation tests in the evaluation of the treatment of ventricular tachycardias with amiodarone].

The role of provocation tests for the assessment of amiodarone therapy in patients with ventricular tachycardia remains a subject of controversy: recent studies seem to show that the ability to initiate VT in patients on amiodarone is compatible with a good long-term result. Eighteen patients, 16 male and 2 female, average age 56 years, were treated with amiodarone (600 mg/day in 15 cases, and 400 mg/day in 3 cases) and submitted to provocative tests before and after treatment. The mean follow-up period was 14 +/- 4 months.

[Electrophysiological effects of encainide in man].

Encainide is an antiarrhythmic agent under evaluation; it is effective in ventricular and supraventricular arrhythmias. Its electrophysiological effects seem to differ according to the route of administration, oral or intravenous, probably because of the effects of active metabolites. Two electrophysiological studies were carried out in 20 patients, under basal conditions, and after 4 to 10 days oral administration at doses ranging from 75 to 300 mg/day.
