[Clinical aspects and prevention of pneumoconiosis caused by inorganic dusts (author's transl)].

Anthracosilicosis and asbestosis are the most important types of pneumoconioses induced by inorganic dust. They produce entirely different damage to the broncho-pulmonary system. Anthracosilicosis graded B or C roentgenographically is very often accompanied by obstructive respiratory disorders; in asbestosis restrictive disturbances predominate. The question whether obstructive lesions also tend to occur remains to be solved. Dyspnoea often accompanied by bronchitis is the main clinical feature. Anthrocosilicosis is amenable to therapeutic measures which have resulted in a considerable prolongation of the life span of these cases. Improved dust control is the most rational prophylactic measure. Abstention from smoking also plays a part.
