Epidemiological Profile of Snake Bite in South 24 Parganas District of West Bengal with Focus on Underreporting of Snake Bite Deaths.

Background: Snake bite is a neglected public health problem in India. Very few community based epidemiological studies in India have been published so far on this issue. Most of the studies were carried out on hospital data. Previous community-based survey in the state revealed that only 22% snake bite victims attended hospitals. Objectives: The objective of the present study is to fi nd out the epidemiological profi le of snake bite in eight blocks of the South 24-Paraganas district of West Bengal and to explore the under reporting of snake bite deaths in health facilities in that area during the study period. Materials and Methods: A retrospective analysis of snake bite data was carried out from a community-based epidemiological survey on 1.9 million populations. This survey was done door-to-door from January 2009 to October 2010 to get epidemiological profi le of snake bite of the previous 2 years. The data of direct survey was compared with the offi cial report of the same area to evaluate the hospital-based data with focus on underreporting of snakebite deaths. Results: A total number of snake bite cases as found in the survey in the study area was 4871. There was a huge gap between the two data (direct survey and offi cial data). Only 7.23% snake bite deaths were offi cially reported. Only 22.19% of the snake bite victims attended the hospitals. Nearly 65.7% of the snake bite deaths were due to common krait bite, most of them occurring in the months of June to September. Conclusions: Offi cial reporting system is still having a huge defi ciency in India. Snake bite needs to get more attention from the health authority.

An epidemiological study on risk factors of diabetes mellitus among patients attending a medical college hospital in Kolkata, West Bengal.

Two hundred and thirty cases of diabetes mellitus were selected in a case-control fashion by applying systemic random sampling technique taking 20% of the patients attending the diabetic clinic of Calcutta National Medical College during the period from January to June, 2003 to find out association and risks of some socio-economic and demographic factors with the occurrence of diabetes mellitus. Controls were selected from the patients admitted in the department of surgery in the same period. Factors like physical activity, socio-economic status, residential status, family history and obesity have shown statistically significant association with diabetes. For physical activity the estimated relative risk is maximum in case of sedentary worker where the odd's ratio was 9.4. So far other factors are concerned the estimated relative risk of diabetes was 5.1 in case of urban population, 6.2 in case of positive family history, 2.5 in case of upper and upper middle classes, and 2.4 in case of obesity in comparison to their respective reference category.

Syndromic approach for determination of reproductive tract infections among adolescent girls.

The present study shows overall prevalence (64%) of reproductive tract infection among adolescent girls, based on self-perceived symptoms. Mean age of respondents were found to be 17.8 +/- 0.82 years and mean age at marriage and mean age at first pregnancy were 17.2 years and 17.5 years respectively; 35.35% of girls in the present study were married. In addition, no significant difference was observed between unmarried (60.10%) and married (71.17%) reproductive tract infection groups. Moreover, no significant association was present in prevalence of reproductive tract infection between the Muslim (67%) and the Hindu (60%). Highest prevalence (84.06%) of reproductive tract infection was observed among illiterate girls and with improvement of educational status there was decrease in the prevalence and the association was found highly significant. Significantly, higher prevalence (72%) was observed among members of family size 7 and above.
