[Pleural involvement and functional effect of asbestosis in 380 exposed patients].

A large number of pleural abnormalities was detected by radiological and functional monitoring of 380 persons (mean age: 47 years) working in an asbestos processing factory. There were 127 cases of parietal pleura thickening (after 22 1/2 years' exposure), 11 cases of pleural calcifications (after 26 years' exposure) and 29 cases of obliteration of the costophrenic angle. Fourteen images of pulmonary asbestosis were encountered, 7 of which were associated with pleural effusion; they occurred at a mean age of 50 years, after 22 years' exposure. Pleural lesions had a restrictive influence on respiratory function in 24% of the cases and were sometimes painful. Small airway obstruction was detected by flow-volume loops in 9% non-smokers with pleural thickening, which suggests that intra-radiological lung lesions exist in asbestosis.

[Occupational angioneurotic disorders provoked by vinyl monochloride and vibration].

Microcirculatory disorders of the extremities may have an occupational origin, which it is desirable to specify. Exposure to vinyl monochloride results in a chemical nuisance which also proved to be carcinogenic in man. Strict preventive measures are therefore enforced in the industry and angioneurotic disorders should no longer be observed. Use of vibrating tools results in a microvascular response to a physical nuisance which is difficult to prevent completely. In both cases the physiopathology is not well-known, but compensation is possible as occupational diseases. Repeated trauma of the ulnar artery, and/or its superficial palmar branch are, on the contrary, the main explanation for hypothenar hammer syndrome, which is easily prevented by mere adjustment of the work position and occupational movements: the conditions for medico-legal compensation for this particular syndrome, which is still not listed among occupational diseases, will be in effect in the very near future.
