The prevalence of chronic nonspecific pulmonary diseases was studied in 1880 industrial workers from Russia. The diseases were reported in 26.5% of the examinees. Fluorograms of chronic bronchitis patients indicated residual posttuberculous bronchopulmonary changes in 28.5% of the cases (p < 0.01). By form the bronchitis depended on the variety of the posttuberculous alterations: 76.4% of the asthmatic bronchitis sufferers had minor residual posttuberculous changes (petrifaction of intrathoracic lymph nodes), those with irritative bronchitis had extended posttuberculous changes in 72.7%.
