Lymphadenopathy is the commonest presentation in lIIV positive individuals. Fine needle aspiration cytology of 196 HIV positive patients was studied during six monthly review. 75% paients in this stud)' who were asymptomatic were detected to have lymphadenopathy during the surveillance. 82% had lymph nodes smaller than Icm size, Lymphadenopathy at more than one site was observed In 46.8% cases. Commonest opportunistic infection noticed was tuberculosis (TB) in~.2%. Cyto-morphologically reactive pattern with Add fast bacilli (AFB) poshivfty was observed in 16.4% of TB cases. In 2.9% cases AFB were detected even in the tissue fluid. Negative Images of AFB were observed in the macrophages in 3 cases. TB was detected with equal frequency In both asymptomatic and symptomatic groups. Axillary nodes pose problem due to deeper location. False positives were a case of dermatopathic lymphadenopathy and a case of Kimura's disease. False negatives include two cases of TB lymphadenitis. Pathogens should be looked for Irrespective of cyto-morphology. Biopsy should be done to confirm cases of lymphomas. Fine needle aspiration cytology should be included In the protocol of six monthly review of HIV infected cases.

Seropositivity to B burgdorferi suggests infection by the organism and presence of Lyme disease in these areas. Further population and vector biology studies are required to find out the exact species involved in transmission of the organism.

Incidence of HIV infection in patients with tuberculosis was found out by serological method (ELISA) with confirmation by Western Blot analysis. Out of 2116 tuberculosis patients tested for HIV, 150 cases were found to be positive for HIV infection (5.73%). Drug susceptibility to first line antitubercular drugs was carried out in 1378 isolates from HIV negative cases and 68 isolates from AIDS cases. The overall resistance pattern to one or more drugs was seen in 13.78% of isolates from HIV negative cases as compared to 7.2% isolates in AIDS cases. Multidrug resistance (MDR) was seen in 8.9% of isolates from HIV negative cases as compared to 4.4% of isolates from AIDS cases.

Depending on prevalence rate, HGV could not be implicated as cause of acute viral hepatitis. Persons with parenteral risk factor (multiple blood transfusions and those undergoing dialysis) had higher prevalence rate as compared to healthy individuals.
