Microsurgery in the diabetic foot.

The treatment of serious tissue defects on the diabetic foot is complicated and tedious because of a combination of pathogenetic mechanisms that influence healing. Diabetic neuropathies (sensory, motor, vegetative), ischaemia and microangiopathies contribute in varying degrees to the adverse healing. The submitted three-year prospective study was focused on an analysis of the pathogenetic factors with the objective of defining the indications for one of three types of microsurgical transfer: 1.

[Symptomatic and silent myocardial ischemia during drug therapy and after aortocoronary bypass].

In 53 patients with stable angina pectoris 24-hour ambulatory electrocardiographic monitoring (Holter) and bicycle ergometry were used before and six months after a coronary bypass. The examination before operation was made while anti-ischaemic medication was administered, the examination after revascularization was done without medication. The patients were divided into group A (31 patients where complete revascularization of the myocardium was made) and group B (22 patients with incomplete revascularization) and the results were compared during medication and after aortocoronary bypass.

[Betaxolol hydrochloride in the treatment of mild and medium hypertension--long-term effects].

All available beta-blockers are effective in the treatment of high blood pressure. Differences in the pharmacokinetics are important as they can have an impact on their clinical use. Betaxolol, a beta-1-selective blocker has a long biological half-life which can control the blood pressure and pulse rate for 24 hours.

Transmitral flow velocities and times during stress transthoracic echocardiography in patients with myocardial ischaemia.

Twenty-nine men with chronic stable angina pectoris were investigated using stress electrocardiography (ECG) and stress transthoracic echocardiography by means of transoesophageal stimulation of the left atrium. At rest and after each stimulated frequency, ECG and 2-dimensional echocardiography combined with Doppler were performed simultaneously. Fourteen patients without ischaemia at stress ECG and two patients who were subjected only to two different frequencies of stimulation were excluded from our study.

[Atrial-triggered and ventricular-inhibited ventricular VDD pacing with atrial and ventricular single catheter electrodes--the Phymos MPS pacemaker].

Optimal treatment from the haemodynamic aspect in complete atrioventricular block is dual-chamber DDD pacing. It makes possible atrioventricular sequence and adaptability of the frequency of ventricular pacing to the load under the control of the sinoatrial node. DDD pacing calls, however, for an atrial and ventricular electrode on two leads.
