Tuberculous infection among children continues to be a significant cause of morbidity. The symptom complex are so variable
among children that the final diagnosis often rests on the laboratory tests. Proper interpretation of the tests, specially
tuberculin test and radiographic studies, are necessary for establishing correct diagnosis. The usefulness of tuberculin test
in both unimmunized and BCG vaccinated children is highlighted. BCG accelerated response as a test should be reserved for
identifying serious form of pulmonary disease or CNS tuberculosis when the tuberculin test is negative. Radiographic assessment
may be sensitive in some instances but not always specific and hence needs cautious interpretation. Tuberculosis among BCG
vaccinated children though not uncommon, needs proper documentation. Current trends in the management of tuberculosis including
CNS forms are briefly outlined. 相似文献

An Integrated Vector Management (IVM) strategy was implemented from 1981 to 1985 in one part of Pondicherry, South India, for the control of the bancroftian filariasis vector Culex quinquefasciatus (the IVM area). The rest of the town (the comparison area) received the conventional larvicidal input. After 1985 both the areas were managed conventionally. The switch to conventional strategy resulted in an increase of vector density in both areas. The microfilaraemia prevalence in humans showed a general decline (P less than 0.05) from 1986 to 1989 only in the IVM area whereas its intensity did not change significantly in either area. While the age-specific rate of gain of infection was generally unchanged in the IVM area, an increase in all age classes was observed after 1985 in the comparison area, where the Annual Transmission Index was high during the previous years. In both areas the rate of loss of infection increased during 1986-9 compared to 1981-6. The results suggest that 3 years is too short a period to relate the changes in entomological parameters to those in the microfilaraemia status of the population. 相似文献
