[The whiplash injury. An overlooked and casually treated syndrome].

The whiplash trauma is defined as hyperextension followed by hyperflexion of the cervical spine or the reverse. The lesion occurs mainly in the occupants of a motor vehicle into which another vehicle collides from behind. Even when there is no radiographic evidence of injury, considerable lesions of the soft tissues may, nevertheless, be present. Review of the literature and the present authors' investigations reveal that up to 80% of the patients have chronic symptoms and 10% of these are severe enough to cause incapacity. The therapeutic regimen has not been well investigated but, at present, intermittent cooling and support by a collar for a few days followed by rapid mobilizing and exercises within the limit of pain are recommended.

Occupational lung function impairment in never-smoking Danish welders.

In order to study the effect of welding fumes on lung function, 74 high-exposed welders and 31 age-matched electricians were examined in 1982. None had ever smoked tobacco or been exposed to known or potentially noxious agents to the lungs. A significant difference was found between the welders and the control group in vital capacity, total lung capacity, forced expiratory volume in one second, peak expiratory flow rate, maximal expiratory flow rate at 75% of vital capacity, diffusion capacity and slope of the alveolar plateau. The lungs of the welders were physiologically 10-15 years older than those of the control group. Thirty percent of the welders had a well defined respiratory disease. Their lung function impairment was predominantly obstructive (16 persons), but restrictive patterns were also seen (6 persons).

Respiratory symptoms in Danish welders.

In order to study the effect of welding fumes on respiratory symptoms a cross sectional study was performed in 1982 among 2,660 welders, primarily shipyard welders, compared with a control group of 881 electricians. Only workers more than 34 years of age and in work at the time of the study were selected. Information about respiratory symptoms (using standardized BMRC questions) and exposure was obtained through a self-administered questionnaire. Seventy-four never-smoking welders and 31 never-smoking controls were selected for detailed clinical interviews and extended lung function tests. This article presents the results of the questionnaire study. The welders showed a significantly higher prevalence of chronic bronchitis: 21% versus 9% in the control group (p less than 0.01). The difference could neither be explained by differences in age or smoking habits nor by exposure to other air polluting substances. Other symptoms from the lower and upper respiratory system were also significantly increased among the welders. A dose-response relationship was found between exposure to welding fumes and the prevalence of symptoms from both the upper and lower respiratory system.
