[Current methodologic approaches to the study of epidemiology extrapulmonary tuberculosis in the Russian Federation].

The study of the extrapulmonary tuberculosis epidemiological situation by using the routine methods leads to misinterpreted and subjective assessment of epidemiological parameters. The application of untraditional epidemiological analysis allows one to ascertain that in 1986-1990 the extrapulmonary tuberculosis epidemiological situation in the areas where the Saint-Petersburg Research Institute of Phthisiopulmonology is monitoring it is very similar to the average federation situation both in the incidence of active extrapulmonary tuberculosis and in the magnitude of changes in the rates of its incidence and prevalence. The lack of significant extrapulmonary tuberculosis shifts is the evidence that the existing measure system for detecting and treating patients in the areas (in the Far Eastern areas and autonomous districts of the Far North in particular) is far from perfect and it yields no adequate results in the prevention, treatment and diagnosis.
