P.C. Sen Memorial best paper award on rural health practice: A study on visual acuity and vitamin A deficiency among primary school students in Naxalbari Village, Darjeeling district of West Bengal.

331 primary school students studying from Nursery classes to Class IV in 2 randomly selected schools in Naxalbari Village in Darjeeling district of West Bengal were tested for visual acuity (VA), Vitamin A deficiency (VAD) and Bitot's spot. 329 students could be tested for visual acuity whereas all 331 students were tested for VAD and Bitot's spot. The prevalence of abnormal Visual Acuity (VA) (VA < 6/9 in any eye) in this study group was 3.65% and it was highest in 7-8 years age group in both the sexes contributing to 75% of the total students having abnormal VA. All these children fell within 50th percentile of weight and height for their respective age and sex. Hindu & ST children accounted for 91.67% & 50% abnormal VA respectively; however, when presence of abnormal VA was compared with its absence between 2 sexes, Hindu and Muslim students and in different castes, no statistically significant differences were found (p > .05). Students of Class-I and Class-II contributed 25% and 50% respectively and together accounted for 75% of abnormal VA. Prevalence of VAD was 8.16%. Among sufferers of VAD Hindus (81.48%) and ST (51.85%) were the main contributors; the differences between presence and absence of VAD in 2 sexes, among 3 religious groups were not statistically significant (p > .05); however, differences among ST and NonSCST groups, and again SC, ST and Non-SCST groups were statistically significant (p < .05). Prevalence of Bitot's spot was 3.63%. Among the students having Bitot's spot, females (58.33%) outnumber the males (41.67%); but the difference between presence and absence of Bitot's spot in 2 sexes was not statistically significant (p > .05). 83.33% each of Hindus and STs had Bitot's spot. No SC and no Muslim student had this spot; the differences between presence and absence of Bitot's spot between Hindu and Christian students were statistically significant (p < .01); similarly when the findings were considered between ST and NonSCST students the difference was found to be statistically highly significant (p < .001).

Some clinico-epidemiological aspect of bronchiolitis among infants and young children--a hospital based study.

A hospital based prospective study was carried out from 1st October 1998 to 30th September 1999 on children with clinical diagnosis of bronchiolitis in OPD and indoor patients of the Department of Paediatric Medicine, Medical College Kolkata. The objective of the study was to find out the proportional case rate and clinico epidemiological features of the disease. The effectiveness of nebulized salbutamol among bronchiolitis children was also looked into. The proportional case rate was found to be 4.65%. Low birth weight (LBW)/premature babies (51.11%) malnutrition (40%), nonimmunization (55.55%) & non breastfeeding practices (48.88%) were significant risk factors for severe bronchiolitis. Response to nebulized salbutamol was remarkably higher (70%) in 6m to 12m age group.

An evaluation of bed management in a rural hospital adjacent to Indo-Nepal border in West Bengal.

Bed management is one of the important activities for efficient hospital management. The present study on evaluation of bed management in a rural hospital revealed that the total bed capacity could not be utilised. The turnover rate, turnover interval, bed occupancy rate and average length of stay were closely corroborating.

Epidemiological correlates of dental caries in an urban slum of West Bengal.

The overall prevalence of dental caries was found to be 57.47 percent in an urban slum irrespective of sex, with a maximum of 75.88 percent in the age group of 5-9 years. Habit of taking hard and sticky food, bad oral hygiene were some of the important epidemiological correlates. Fluoride content of drinking water did not show any significant role.

Drug consumption pattern in low socio-economic group in an urban community.

117 families, having a total population of 558 were studied regarding drug consumption pattern. It was found that the average no. of episodes per person was 0.99 of which drugs were consumed for 72% of episodes. Significant difference was observed in consumption of drugs between males and females. Allopathic medicines were consumed for 93.3% of the episodes and the major source (53.8%) of medical care was from private practitioners. It was seen that the number of drugs consumed per episode of sickness rose as the per capita income increased. Vitamins and Minerals (22.3%) were the main group of drugs consumed. Drugs acting on the alimentary system (17.5%), Respiratory System (14.7%), Antimicrobials (14.6%) and Analgesics (10.8%) contributed to 80% of drug intake.

Length of stay of in-patients of a gynaecological ward in a sub-divisional hospital in West Bengal.

Bed utilisation efficiency and hospital resource utilisation are of prime importance to remove the "Hospital Bottlenecks" which in turn reduces length of stay of in-patients. The present study on in-patient system in Gynaecology Ward of a non-teaching hospital revealed that a considerable number of bed days were unnecessarily lost during various activities related to investigation, operation and post-operative stay. Overall length of stay found in this study (14.02 days) is considerably higher than Indian optimum. Average time-lags found between admission to pre-operative investigation and post-operative stay were 3.25 days and 10.22 days respectively.
