[Lumbar phlebography: methodological choice and reliability in the radiographic study of lumbar disk hernias].

Lumbar epidural venography was used as the examination of choice in the investigation of suspected disc herniation in 270 patients. Compression or occlusion of an epidural and/or radicular vein at the disc level is the most significant venographic abnormality. In 110 patients operated on, the reliability of lumbar epidural venography was equal to 97.

Effects of nifedipine, acebutolol, and their association on exercise tolerance in patients with effort angina.

The action of nifedipine (N), acebutolol (A), and their association (A+N) was studied in 16 patients suffering from effort angina with documented coronary artery disease. The therapeutic action was valued by bicycle effort stress test after oral administration of medications in comparison with placebo (P), following a double-blind random sequence of treatments. Working capacity significantly increased after A (507 +/- 450 mkp, p less than 0.

[Use of glucagon in the reduction of intussusception; presentation of one case (author's transl)].

Intramuscular glucagon was used in one patient with ileocolic intussusception when standard therapeutic barium enema reduction failed. Reduction was accomplished following administration of glucagon and a repeat barium enema. Use of the two methods together may improve the success rate of nonoperative reduction of intussusception.
