[Immunological changes in old-age group children with primary and secondary tuberculous infection].

In modern society, there is a rise in the incidence of tuberculosis in all age groups, including children and adolescents. In old age group, a specific inflammation is detectable from Mantoux test results only in every four children. Tuberculous infection is diagnosed in half of cases when they turn to physicians for complains.

[Predictors of the progress of latent tuberculosis to clinically active one].

The question recently arises as to the diagnosis of tuberculous infection at early stages of its development. Tuberculin diagnosis ranks below due to the rise ofcomorbidity, including allergic diseases. There is increasing evidence for the leading role in the development of this or that type of tuberculous infection.

[Tuberculin sensitivity in old children with new-onset active tuberculosis].

In recent years, there have been reports on the reduced diagnostic value of a tuberculin test with 2 TE PPD-L. Tuberculin diagnosis is a ground for suspecting tuberculosis only in 25.9 +/- 0.

[Contingents of young children at a specialized hospital].

The case histories of 80 children aged 0-3 years with varying primary tuberculosis who were treated at the Pediatric Specialized Unit in 1990-1995 are analyzed Specific intrathoracic lymph nodal lesions (33.75%) were more common in the pattern of clinical tuberculosis, the primary tuberculosis complex being 2 times less. A third of children had a complicated course of local types of tuberculosis.
