[Results of an epidemiological study with subsequent specialized diagnostic studies in dust exposure].

Preparing a special occupational health follow-up a cross sectional study in 304 dust exposed workers was performed. According to these screening results 23% of the workers examined revealed as fit only under special conditions. Clinical examinations confirmed these judgements except a small group of 2.

[Functional significance of lung siderosis in electrode welders].

56 electric arc welders found in a cross-sectional study to show pulmonary siderosis in full size x-rays were clinically examined. Looking for the discussed functional, relevance of such lung diseases in welders the diagnostic program included spirometry, flow-volume-curves, body-plethysmography, single breath diffusion capacity, pulmonary compliance and ergooxytensiometry. The results are supporting that "lung siderosis" in welders is associated with slight functional deterioration in the type of interstitial lung diseases.

[Chronic obstructive airway diseases caused by long-term occupational exposure to asphalt pyrolysis products].

The paper reports on 6 roofers who have been specialized on production of damming up roofs and insulation of wet rooms for 20 years.
