An evaluation was presented that related clinical, radiological and functional abnormalities among 92 male workers in an asbestos cement factory. Twelve of these 92 had normal chest roentgenograms. Among the abnormalities discovered were five instances of pulmonary fibrosis, nine benign pleural thickenings, and 57 associated pulmonary fibrosis and nonmalignant pleural changes. Diagnosis of malignant pleural mesothelioma was established in eight cases. For one patient there was a bronchial carcinoma with concomitant asbestosis and pleural plaques. Asbestos (1332214) related disease was identified in 80 subjects. Abnormalities in respiratory function tests frequently occurred without a clear relationship to put forward dyspnea. A restrictive function pattern was noted in half the population, and normal spirographic values in 20 of 100 tested. A mixed picture of restriction and obstruction was noted in about 30 of the 100 cases. Bronchitis caused alterations in spirographic values but had no significant modification in transfer factor and blood gases. Pulmonary function measurements were more depressed in bronchitic than in nonbronchitic subjects and the restrictive and obstructive lung function profile was underscored.
