[Group tuberculous contamination in preschoolers]. / Contaminari tuberculoase colective la copii prescolari.

The study of a new collective tuberculosis contamination is proper for us to report news about the antituberculosis fight. In 1997, an ill teacher with cavity produced 19 cases of tuberculin turnings in a class with 25 children, but none of them had tuberculosis. We tried to find an explanation. We studied another 3 epidemiological events. In 1970, a teacher from Holbav produced 80 tuberculin turnings with 42 ill children. In Sacele another teacher with cavity produced 39 tuberculin turnings with 5 ill children. In Prejmer, in 1988 a sick child with cavity made himself 28 tuberculin turnings with a single case of illness. We tried to explain these differences: similar sources (patients with cavities) and the same conditions of illness but different effects. Our epidemiological investigations showed that in Holbav only 3.6% of children had BCG vaccine; in Sacele were 18%; in Prejmer were 98%; in Codlea 96%. BCG vaccination prevents tuberculosis. But in this case is another problem, did all the tuberculin turnings signify a virulent infection? After a year when we tested again the children, we found that for 58% of tuberculin turnings the reaction diminished considerably. We consider that, this is the particularity of the evolution of the postvaccinal allergy. We conclude that hyperreactivity may be a transitory exacerbation of the postvaccinal allergy and not an evidence of the infection. BCG vaccination reduces the risk of tuberculosis even when the infection is important and virulent.

[The diagnosis and surgical treatment in the case of 2 rare sites of hydatid cyst in children]. / Diagnostic si tratament chirurgical în cazul a 2 localizari rare de chist hidatic la copil.

In the Clinic of Paediatric surgery of the Hospital "Gr. Alexandrescu" there have been hospitalized and operated 2 cases of hydatic cyst within 1990-1993. The both patients had tumoural structures, one of them being placed on left axillary area (S.E.--11 years old) and the other on the left thigh (M.S.--5 years old). The both patients have been surgically operated, the said tumoural structures being eradicated. The anatomic-pathological examination attested that for the both patients the diagnosis was the hydatic cysts are localized on pulmonary, hepatic or splenic areas, we considered to be interesting to inform you about details of two rare localization of this disease.
