[Causes of local forms of primary tuberculosis in ways of their detection in children in an area with high morbidity rates in the adult population].

Thirty-six children with new-onset local tuberculosis were followed up to assess its causes and the ways of its detection. The predominant form of primary tuberculosis was that of inthrathoracic lymph nodes. Six examinees had complicated tuberculosis, the latter being attended by circumscribed lymphogenic semination in 5 of them and by the bronchopulmonary syndrome in one. Eight patients were diagnosed as having a primary tuberculous complex. Tuberculin diagnosis revealed a primary tuberculous process in 33 of the 36 patients. In 25 of the 36 patients, the diagnosis was established by the routine X-ray tomography. Computed tomography was performed in 11 patients, 3 of them being diagnosed as having minor tuberculosis of intrathoracic lymph nodes, it could specify the extent and site of the lesion in the remaining patients. The risk factors included ineffective or absent BCG vaccination; a family contact with a tuberculosis patient; no preventive measures in the nidus of infection; comorbidity; a family's social ill-being.
