This is a brief presentation on pulmonary tuberculosis. It contains numerous illustrations, mostly prepared from x-ray films of the chest. Approximately half a page is devoted to the first infection type of tuberculosis and the remainder of the book to reinfection clinical forms of the disease. Various phases of the examination for tuberculosis, such as the tuberculin test, symptoms, physical signs and x-ray films, are outlined. Under treatment such subjects as hygienic regimen, fresh air, diet, drugs and physical therapy are briefly discussed. The discussion of collapse therapy includes artificial pneumothorax, oleothorax, pneumonolysis, phrenicectomy and thoracoplasty. In approximately ten pages prevention is discussed, and considerable emphasis is placed on predisposing or contributing causes of tuberculosis, such as living in poorly ventilated and damp houses.
