Absolute coronary risk analyser--a tool for managing coronary heart disease risk.

Objectives: The aim of the present study was to develop a coronary risk analyser which can calculate authentically the absolute coronary risk of an individual for coronary risk management.

Methods And Results: After extensive literature survey was done to derive the most appropriate method to calculate the absolute coronary risk. Joint British recommendations derived from Framingham's heart study were adopted for its supreme sensitivity and specificity.

Dose and frequency of anti-snake venom injection in treatment of Echis carinatus (saw-scaled viper) bite.

Objectives: To assess the adequacy of initial standard dose of 100 ml of polyvalent anti-snake venom (ASV) and subsequent doses of 50 ml in correcting coagulation dysfunction in cases of viperine bite and to find the incidence of recurrence of coagulation dysfunction. The other objective was to correlate total requirement of ASV with initial coagulation profile.

Methods: Forty two adult patients of Echis carinatus bite with features of systemic envenomation, admitted over a period of 18 months, were monitored every six hours with bed-side clotting time (CT) and were given an initial standard dose of 100 ml of ASV intravenously.

Correlation of renal status with hematologic profile in viperine bite.

Viper venom is mainly hemotoxic and causes coagulation disorders. One of the serious complications of viperine bite is renal failure. Forty adult cases of viper bite with systemic envenomation were studied for renal abnormality.
