[Gender-specific differences of risk factors of atherosclerosis. A study of 3,850 Vienna employees].

Atherosclerosis is the most frequent cause of death in Austria as well as in the other western industrialized countries. Sex specific differences in the various age groups concerning relative myocardial infarction-mortality stimulated us to investigate the risk factors for atherosclerosis in 3850 employees. An extensive lipid status, liver and kidney function parameters were determined, the blood-pressure was measured, and a cardiovascular centered case history was examined.

[Risk factors of atherosclerosis--primary examination of Vienna employees].

In the course of an atherosclerosis intervention study, a basic medical check-up of 2105 out of 4800 employees of a Viennese banking house was carried out (37.1 +/- 11.0 years, 54.

[Angiologic, neurologic and orthopedic findings in vibration exposed chain saw operators].

The present study was designed to evaluate and correlate angiological, neurological and orthopaedic findings in lumberjacks, professionally exposed to vibration by chain-saws with a frequency of 40 to 120 Herz. Raynaud's phenomenon was diagnosed in 16 of 33 subjects. The nerve conduction velocity was delayed in 13 of 32 lumberjacks, the sulcus nervus ulnaris syndrome was diagnosed in 41%, the vibration threshold was abnormal in 10/32 cases.

[Acute effect of prostigmin on lung function and breathing of patients with myasthenia gravis at rest and following ergometric exercise].

The acute effects of a single intravenous Prostigmin injection (0.5 mg) on lung function and gas exchange during rest and bicycle ergometry were measured in 26 patients with myasthenia gravis. The mean age of the patients was 44.

Inhibition of acetylcholine-induced bronchoconstriction in asthmatics by nifedipine.

The calcium-dependent constriction of bronchial smooth muscle cells and release of mediators derived from mast cells is important in the pathophysiology of asthma. We hypothesized that nifedipine, a slow calcium channel blocker, would inhibit or attenuate acetylcholine-induced bronchoconstriction in asthmatics. Because one consequence of mast cell activation is the release of platelet-activating factor, we wondered whether thromboxane levels would be increased during acute bronchial constriction in asthmatics.

Bladder obstruction--a rare complication after percutaneous renal biopsy.

In the treatment of diffuse renal disease exact histological diagnosis is of great importance. Biopsy, therefore, is an integrated component of patient management. The most common complication following percutaneous renal biopsy (PRB) is bleeding.

[Comparison of 2 field studies (office and food factory)].

The results of a medical investigation of 973 volunteers (632 bank employees and 341 workers in a food factory) are compared: a marked difference exists between the two groups with regard to body-weight distribution. Significantly more persons with elevated levels of serum cholesterol, triglycerides and glucose are registered in the group of food workers; moreover, the incidence of hypertension, bad teeth and varicosis is also higher in this group.
