[Causes of formation of destructive tuberculosis of the lungs]

It was shown that irregular fluorographic examinations, undetected pathological processes on fluorograms and their erroneous interpretation were the causes of destructive tuberculosis of the lung. Early detection of tuberculosis was hampered by prior nonspecific diseases of the respiratory organs and underestimation of the process activity especially when chronic bronchopulmonary diseases were associated with residual signs of cured tuberculosis. Recommendations for prophylaxis of destructive tuberculosis of the lung are presented.
