[Sputum conversion and behavior of cavitations in the years 1967-1973]
Abstract:
The results of chemotherapy based on an intersanatorial study of 3306 patients with active pulmonary tuberculosis are presented. In 1967 sputum conversion was achieved in 93%; since 1970 the results have been better, with conversion in 96-97%. From 1967 to 1972 the cavitations disappeared in 51-57% of patients with cavitary disease, but in 1972 and 1973 only in 47% and 36% respectively.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
