RESUMEN
Well documented 112 pulmonary tuberculosis patients were studied for the prevalence of human immunodeficiency virus (HIV) seropositivity by using two antibody screening tests along with western blot test. Nineteen of the pulmonary tuberculosis patients were HIV seropositive, 12 were acid-fast bacillus smear positive; 12 patients were tuberculin skin test positive and 15 patients were culture positive. As the incidence of HIV infection is increasing in India, it is observed that patients co-infected with HIV and TB are also on the rise. Recognition of the dual infection and taking adequate steps to deal with this epidemic are needed.

Intraoperative fine needle aspiration cytology (FNAC) for pancreatic and ampullary lesions was carried out under direct vision using transduodenal approach in 97 patients. Cytological findings were classified as follows: positive for malignancy, suspicious for malignancy, benign (normal) cells from duodenum or pancreas, inflammatory and non-representative smears. Suboptimal smears (non-representative, suspicious and inflammatory) were excluded for calculating decision analysis values. Sensitivity for malignancy was 90.5% and specificity 100%. Positive and negative predictive values were 100% and 50% respectively. We conclude that intraoperative FNAC is useful in diagnosing malignant lesions of the pancreas.
