ABSTRACT
Nine hundred and forty cases of breast lesions were subjected to fine needle aspiration. Nine hundred twenty-four of them were females and sixteen were males. Smears from the 60 female cases were rejected as unsatisfactory. Of the remaining 864 female cases (aged 15 to 72 years) 704 (81.4%) were benign. Histopathological correlations were done in 448 cases with diagnostic accuracy of 97.3%. One hundred and sixty (18.5%) out of 864 females were malignant and cytohistological correlation was done in 142 cases with 98.6% corroboration. Ten of the 16 male cases were histologically examined with full corroboration. Overall accuracy considering both males and females was 98.6%. Though there was underdiagnosis involving 12 cases of infiltrating ductal carcinoma when the lesions were small and deeply situated there was no overdiagnosis in this study.

Fifty patients of acute renal failure following Viperine snake bite were studied. Oliguria (100%), local swelling (48%) and bleeding tendencies (42%) were the predominant clinical features encountered. Of the 25 patients in whom detailed coagulation studies were done, 24 patients had disseminated intravascular coagulation (DIC) and 1 had primary fibrinolysis. DIC was commoner with Russell's viper bite (62%) in comparison to Echis carinatus bites (40%). Renal histology obtained in 29 cases revealed tubular necrosis (35%), cortical necrosis (24%) tubular degeneration (17%) and glomerular changes (17%). Ballooning of glomerular capillaries (59%), splitting of glomerular basement membrane (40.7%), swelling of endothelial cells (29.6%), and focal proliferation of mesangial cells (17%) were the significant glomerular changes encountered. 20 (40%) patients succumbed, DIC (50%), irreversible shock (30%) and septicaemia (20%) being the immediate causes of death. Development of oliguria within 24 hours of snake bite and cortical necrosis were associated with higher mortality.
