Hazards in hyperbaric medicine.

During the period April 1965 to April 1968 observations were made on 285 patients and 357 staff exposed to air and oxygen at pressures of 1 to 3 atmospheres absolute in a hyperbaric unit. Decompression sickness was not noted and an annual radiological skeletal survey failed to show aseptic bone necrosis; the incidence of otitic barotrauma was 4.7%. Oxygen toxicity was not observed in any patient. It is suggested that pressures in this range are relatively safe in a specialized medical hyperbaric environment.

Correlation between lung asbestos count at necropsy and radiological appearances.

In the first 100 of a series of 600 consecutive necropsies for which a chest x-ray film had been taken within a year of death the features of asbestosis were observed in eight of the nine cases where the asbestos count at subsequent necropsy exceeded 40. In only one of these cases had the diagnosis of asbestosis been suggested during life. The higher the asbestos count the greater the likelihood of radiographic abnormalities, particularly calcified and non-calcified pleural plaques on the chest wall and diaphragm.
