[New cases of tuberculosis of respiratory organs during phases of reverse development in children].

Out of 313 preschool children treated in a specialized children's hospital for local tuberculosis, 23.6% of cases were first diagnosed in phases of reverse development. 12.8% of children cured spontaneously. Local activation as infiltration of intrathoracic lymph nodes and dissemination to the lungs and other organs occurred in 8.1 cases. The activation was seen both in children with spontaneously cured tuberculosis and those after chemoprophylaxis. It is concluded that all the children with newly detected tuberculosis in reverse phase, irrespective of previous chemoprophylaxis, should be treated in hospital with subsequent observation of the phthisiologist.
