[Lumbar phlebography: methodological choice and reliability in the radiographic study of lumbar disk hernias]. / La flebografia lombare: scelta metodologica ed affidabilitá nello studio radiografico dell ernie discali lombari.

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 97.2%.

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 0.05), after N (1,140 +/- 767 mkp, p less than 0.001), and after A+N (1,198 +/- 644 mkp, p less than 0.01). The increments of work after P administration were not significant. Moreover, fatigue instead of angina appeared as a stopping criterion in 8 patients after A+N, and in only 1 patient after P, A, and N.

[Use of glucagon in the reduction of intussusception; presentation of one case (author's transl)]. / Impiego del glucagone nella reduzione dell'invaginazione intestinale; presentazione di un caso.

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.

[The intra-arterial use of lidocaine to reduce pain in aorto-femoral arteriography (author's transl)]. / L'impiego intra-arterioso della lidocaina per ridurre il dolore nell'arteriografia aorto-femorale.

In 50 patients subjected to aorto-femoral arteriography, the examination was carried out with and without the addition of 1 cm3 of 2% lidocaine per 10 cm3 of contrast medium; in 43/50 lidocaine led to a more or less notable reduction in pain without side-effects.
