Cineradiography of the braced normal cervical spine. A comparative study of five commonly used cervical orthoses.

Five orthotic devices were selected for a study of their effectiveness in immobilizing the cervical spine. These orthoses were fitted to subjects with a normal range of motion of the cervical spine. Motion pictures were made from a lateral view while the patient actively flexed and extended his cervical spine as well as from the frontal view with the patient rotating to each side and bending to each side. The soft cervical collar offers very little immobilization. The firm plastic Thomas collar restricts about 75 per cent of flexion-extension, rotation and lateral bending. The four-poster orthosis gave 80 to 85 per cent restriction of flexion-extension and lateral bending but only restricted 60 per cent of rotation. The long two-poster cervical orthosis caused 90 to 95 per cent restriction of all motions. The Guilford two-poster cervical orthosis restricted 90 per cent of all motions.

Vasoactive intestinal polypeptide (VIP) is not an androgen-dependent neuromediator of penile erection.

The effects of castration on vasoactive intestinal polypeptide (VIP) immunostaining in human corpus cavernosum (CC) and the relationship between VIP immunostaining and erectile function were studied in patients with localised prostate cancer who had (Group 1 = castrated) or had not (Group 2 = control) undergone 3-month neoadjuvant chemical castration before radical prostatectomy. Evaluation of erectile function included medical and sexual history, physical examination, and measurement of total serum testosterone. CC biopsies were taken at the end of radical prostatectomy and samples immunostained with anti-human VIP antibody. Specific staining was quantified by image analysis and expressed in arbitrary units (AU). Chemical castration induced erectile function deterioration in 70% of patients due to loss of sexual interest and confidence in the ability of having an erection rather than reduced ability of obtaining sexually induced erections. Average VIP content was 34.5 AU in Group 1 and 39 AU in Group 2 and this difference was not statistically significant. Chemical castration does not influence VIP immunostaining of human CC, suggesting that VIP is not an androgen-dependent neuromediator of penile erection and that it can be responsible for sexually induced erections in castrated patients.

[Mortality due to causes correlatable to asbestos in a cohort of workers in railway car construction].

A study was made of the mortality experience of a cohort of railway carriage construction workers with the aim of detecting asbestos-induced disease. The cohort included 1534 men who were active as at 01.01.1970 and/or hired up to 30.06.89. Vital status was ascertained for 97.7% of the cohort. The mortality experience of the cohort was compared with that of the population of the Campania Region. Altogether, 194 deaths were observed (SMR: 0.88). Significant mortality deficits were associated with circulatory causes (SMR: 0.64, 58 observed), non-malignant respiratory causes (SMR: 0.59, 12 observed), and accidents (SMR: 0.39, 5 observed). A significant increase in mortality from all neoplasms was detected (SMR: 1.25, 69 observed), mainly due to an excess of lung cancer (SMR: 1.45, 28 observed), pleural cancer (SMR: 4.72, 3 observed), and peritoneal cancer (SMR: 7.47, 2 observed). The excess of mortality from respiratory neoplasms mainly affected subjects who had started employment more than 20 years previously.
