Item Clinicopathological study of acute renal failure following viperine snake bite.(1989-07-01) Merchant, M R; Khanna, U B; Almeida, A F; Acharya, V N; Mittal, B VFifty 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.Item Pattern of renal amyloidosis in western India. A study of 104 cases.(1990-06-01) Mehta, H J; Talwalkar, N C; Merchant, M R; Mittal, B V; Suratkal, L H; Almeida, A F; Acharya, V NA total of 31,266 autopsies and 1556 renal biopsies were scrutinised over a period of 19 years (1968-1986) retrospectively and prospectively, with an aim to study the incidence and pattern of renal amyloidosis in western India. A total of 104 cases with amyloidosis were detected, 41 from the autopsy series (0.1%) and 63 from biopsies (4%). Secondary amyloidosis was seen in 83.7% and primary amyloidosis in 11.5%. The interval between the onset of predisposing disease and first evidence of amyloidosis varied from 2 months to 31 years. Tuberculosis of various organs was the main cause of secondary amyloidosis (72.4%). Nephrotic syndrome was a common mode of presentation (71.4%). Besides kidneys, which were involved in all cases, the liver, spleen and adrenals were other commonly involved organs at autopsy. Renal failure was the leading cause of death (34.1%).Item Prognosis of acute renal failure in pediatrics.(1985-05-01) Shah, B V; Merchant, M R; Almeida, A F; Acharya, V N
