Epidemic dropsy in Trans Yamuma areas of Delhi and U.P.

Thirty patients of epidemic dropsy from seven families scattered in different areas of East Delhi and UP were studied. The age group of the affected individuals varied from 2 years to 55 years. Argemone oil contamination was found in mustard oil used for cooking. Sanguinarine was detected in all suspected oil samples. Pitting edema of legs was the most consistent feature present in all cases. Other prominent features like local erythema and tenderness were present in 80% and 70% cases, respectively. In contrast to earlier epidemics, two striking features were presence of persistent tachycardia without any pyrexia in all the cases and absence of any ocular problems. There was one death due to congestive heart failure and partial recovery in all others in a 2 months follow up.
