Retroanalytical Study of Epidemiological Factors of Rhinosporidiosis.

Introduction  Rhinosporidiosis is a granulomatous disease of humans and animals that is caused by Rhinosporidium Seeberi . This disease is endemic in certain states of India, like Chhattisgarh, Tamil Nadu, Kerala, Orissa, and eastern Madhya Pradesh. We conducted a retrospective, record-based study in the department of ENT & Head and Neck Surgery of a tertiary case institute in Chhattisgarh. Objective  To study the epidemiology of rhinosporidiosis, especially host risk factors. Methods  We conducted a retrospective, record-based study in the department of ENT & Head and Neck Surgery of a tertiary case institute in Chhattisgarh, India. A total of 55 histologically proven rhinosporidiosis patients who were surgically treated in the department over a period of 2 years from November 2014 to November 2016 were included. Results  This study involved 55 histologically proven rhinosporidiosis cases. There were 87% males and 12% females. Most of the cases belonged to lower socioeconomic status (92.73%). All the cases had history of pond bathing. Of 55 cases, 27 cases (49.09%) had O+ blood group followed by A+ in 10 (18.18%), B+ in 9 (16.36) and AB+ in 9 (16.36%). Conclusion  The results of the study showed that the disease was associated with the male gender, young and middle age, low socioeconomic status, rural background, pond bathing and O+ blood group.
