Questions and responses related to the AMA Congress on Occupational Health of 1974 were presented. The topic of occupational pulmonary disease was discussed with respect to: differential diagnoses, removing workers from dusty environments, cigarette smoking, asbestosis, and workman's compensation claims. Cardiovascular disease in occupational medicine was considered in relation to the confidentiality factor in voluntary examinations, the impact of emotional stress, triglyceride screening, misuse of alcohol, and mortality studies. The workshop also described: cardiovascular demonstration, work evaluation, and stress testing (baseline studies and measurement techniques), medical monitoring, and incorrect or absent chemical exposure diagnoses. Emphasis was placed on obtaining accurate occupational and avocational histories, precautionary measures, the relationship between management and the health of laborers, definition of normal testing responses, interpretations based on setting, and mechanisms of toxic effects.
