[Can radiophotographic detection be discontinued in rural areas at the current stage in Rumania?]. / Se poate renunta la depistarea radiofotografica integrala în mediul rural, în etapa actuala din tara noastra

Considering the fact that in the rural environment the population groups at great risk are not sufficiently well known, in the case of tuberculosis, it is recommended that 1 or 2 more integral detection operations be carried out in this environment and to carry out a detailed investigation of the differentiated risk of various population groups.

[Long-term study of the effect of successive surveys on tuberculosis endemia]. / Studiu longitudinal al influentei depistarilor succesive asupra endemiei tuberculoase

A whole rural population of 16359 subjects was followed for a period of 24 years. This period of 24 years is well divided from the viewpoint of the succesive systematic detection three intervals being selected, as follows: a) the stage of usual anti-tuberculous assistance; b) the stage of scientific experimentation consisting in 3 radiophotographic detections repeated every two years and the annual control of groups with high risk, between 1960--1965, completed by integral biological detection in children (every year) and bacteriological controls. The population controls were followed by the diagnosis; c) the stage of discontinuing the experiment when current antituberculous assistance was resumed, between 1966 and 1974. All cases of active pulmonary tuberculosis, that have been recorded through all the methods of investigation over a period of 24 years in all these localities are correlated, on the one hand to one another, and on the other hand with objective documents obtained during the period of intensive control of the population over the 6-years interval. Thus the limits appear more correctly, within which this natural history of the disease can be detected through various types of population control, as well as some practical consequences for the improvement of the technique and of the control methodology in the future.

In the territory of 5 anti-TBC dispensaries in the area of Bucharest 2 circumscriptions have been selected at random in which radiophotographic detection was to be carried out integrally and 2 other circumscriptions were selected for the investigation of groups at high risk of developing tuberculosis. All the new cases of active pulmonary tuberculosis that have been recorded, through all the methods in these 20 circumscriptions in 1973 were analized retrospectively and the reasons appeared that had determined their existence was mentioned or was ommitted on the occasion of previous investigations. These reasons were correlated with the data concerning the method for detection that had been employed, according to the indications of the tuberculosis dispensaries. In view of the evaluation of the degree of real covering of the population in integral rf investigations, the team of the Institute of Phtysiology investigated representative lots of population from each dispensary and checked the catagraphy of the population in the field, house-by-house. It was noted that 20--21% of the subjects that had been programmed for the integral rf examination (according to catagraphic criteria) were absent when the checking in the field, that should have been programmed, were not included in the catagraphy. On the basis of this study the methodology for radiophotographic detection for groups with risk of developing tuberculosis was established.

[Model of eradication of tuberculosis in children in an area with high epidemiological potential]. / Model de asanare a tuberculozei la copii într-un teritoriu cu potential epidemiologic ridicat

In the territory of the Drajna TB dispensary, in the Prahova County, a series of complex measures have been experimented in the course of the second trimester of 1972, intending to prevent and to eliminate tuberculosis in children. Of the 31,731 children aged between 1 and 14 years, 29,496 have been tested with 2 units of PPD-IC65 (93 percent). A proportion of 12,6 percent of those tested presented reactions of more than 10 mm in diameter and 22,779 were vaccinated with BCG (Pasteur-Paris strain). The radiological pulmonary control of the reactors allowed for the detection of 24 cases of tuberculosis all of them new and asymptomatic. The efficiency of the detection was of 0,8 new cases per 1,000 tuberculin tested children or of 0,4 new cases per 100 of reactors that had been x-ray examined. This prophylactic action was repeated in 1973 in 2,219 children aged between 1 and 2-1/2 years that had been ommited in the preceding year and 4 new cases of tuberculosis were detected. In the medical districts in which there was a high prevalence of the children infection total radiophotographic case finding of the adult population was carried out. The result was a doubling of the TB incidence in children in 1972 followed by a 5-fold reduction of the indicators in 1973. The severe forms and death through tuberculosis in children have disappeared. The risk to develop the disease in BCG vaccinated children was reduced to 4,4 0/0000 per year. It is estimated that a generalization over the whole of the county of these prophylactic measures, as applied in the Drajna territory, under the form of a mass campaign, will allow for an improvement of the epidemiometric indicators in children in a relatively short time.
