[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. In ill infants, the causes of primary tuberculosis were no BCG vaccination, familial tuberculosis contact, and infrequent use of specific chemotherapy.
