To the prediction in pulmonary caverns. К. Kotter (Zeit. f. Tuberkul., Bd. 49, No. 5)

Of all the cavernous patients who were treated in the St. Blasien health center in 1919-21, 21.5% were still alive after 6-8 years (or 33%, if we take the same percentage for those whose fate remained unknown as for those who were not lost from sight). Prediction in caverns is closely connected with the quality of the disease process: the so-called early forms give a much better prediction than the late forms; the tertiary forms are much less amenable to internal treatment, and the effusion-progressive forms give an absolutely unfavorable prediction.
