Netting the malaria menace: Distribution and utilization of long-lasting insecticidal net in a malaria endemic area in Bankura, West Bengal.

BACKGROUND & OBJECTIVES: Long-lasting insecticidal net (LLIN) is considered to be a highly effective intervention against malaria under National Vector Borne Disease Control Programme in India. A cross-sectional study was undertaken to assess the coverage and utilization of LLIN and the factors related thereto. METHODS: A survey of 1300 households was carried out in Ranibandh block of Bankura district in West Bengal, India, using lot quality assurance sampling (LQAS) method. Coverage/utilization of 80% was considered as minimum acceptable norm. The weighted sample size was calculated from each village of the block. The sociodemographic, economic information of the household along with the availability and use of LLIN was collected through interview and observation. RESULTS: In total, 7320 individuals including 840 children ≤ 5 yr were visited. Overall coverage of adequate LLIN was 65.4% (± 1.5%) and for children ≤ 5 yr, it was 60.5% (± 1.3%). Overall, 66.1% (± 1.4%) people of all ages and 63.7% (± 1.4%) children ≤ 5 yr slept under LLINs in the night before the survey. Out of 26 sub-centres, distribution of LLINs in 10 sub-centres was below the accepted norm, whereas utilization was sub-optimal in 19 sub-centres. In only 18.2% (± 0.5%) households, LLINs remained hanging during daytime. Poverty, caste, education, perception regarding malarial morbidity and preventive action of LLIN were associated significantly with the distribution of LLIN. Similarly, poverty (AOR = 2.14), threat perception regarding malarial morbidity (AOR = 1.51) and mortality (AOR = 2.52) were positively associated with the use of LLIN. Full utilization of bednets by under-fives of the households was higher in villages with sub-centres. INTERPRETATION & CONCLUSION: Around two-third population of the study area was effectively covered with LLIN. Higher proportion of socially marginalized people received LLIN. Threat perception regarding malaria was directly associated with both receipt and use of LLIN. Behaviour change communication on utilization along with adequate access to LLIN needs to be strengthened.

Junctures to the therapeutic goal of diabetes mellitus: Experience in a tertiary care hospital of Kolkata.

INTRODUCTION: The World Health Organization has declared India as the "diabetic capital" of the world. In controlling of such chronic, mostly asymptomatic disease, patients' role can't be overemphasized. AIMS: To assess the level of compliance to anti-diabetic therapies and to ascertain the determinants of non-compliance, if any. MATERIALS AND METHODS: A cross-sectional observational study was conducted for 3 months in a diabetic clinic of R G Kar Medical College and Hospital, Kolkata. Data were collected by interviewing the patients, examining their prescriptions and laboratory reports and anthropometry after obtaining informed consent. RESULTS: Blood report at the point of data collection revealed controlled glucose homeostasis in 38.93% patients but evaluation of past 3 months report showed only 24.3% had control over hyperglycemia. Glycemic control was seen to be positively related to short duration of disease, compliance to therapies, and high knowledge about diabetes. Compliance to therapies found in 32.22% of study subjects was in turn associated with short duration of disease. House-wives showed poor compliance; insulin treatment with or without oral-anti-diabetic agent showed better compliance. Knowledge of diabetes was significantly high among higher educated; poor among women, house-wives, and rural people. CONCLUSION: Patient-providers collaboration is to be developed through a patient-centered care model based on the mutual responsibility of both so that each patient is considered in the mesh of his/her other goals of life and helped to promote empowerment to take informed decision for behavioral change conducive to control the disease.

A study on habits of tobacco use among medical and non-medical students of Kolkata.

BACKGROUND: Age-old practice "using tobacco" is a well known major global concern as it victimizes all its lovers by a host of chronic noncommunicable diseases including cancer; all develop very slowly and silently, and can cause premature death. OBJECTIVES: To assess the pattern of tobacco use among the medical and nonmedical college students. MATERIALS AND METHODS: A cross-sectional descriptive study was carried out in Kolkata collecting anonymous data from 515 medical and 349 nonmedical college students of two medical and two general colleges, selected randomly. RESULT: Overall prevalence of tobacco use (18.3% vs 43.6%) and smoking (14.9% vs 40.7%) were significantly less in medical subjects, both across the sex and years of study. Lower rate of tobacco adoption at college level, higher quitting rate, correct knowledge regarding uselessness of filter attached with cigarette, and ill-effects of tobacco consumption were observed among medical participants. More nonmedical subjects were increasingly smoking compared to medical students. Filter-tipped cigarette was the top choice, and smoking was more prevalent mode of use among the nonmedical participants, most (62.3%) of whom were mild users. Curiosity was the top influencing factor for the initiation of tobacco use and two-third users wanted to quit. CONCLUSION: Although the mortal habits was comparatively less among medical students, the medical environment seemed to fail to curb the dreadful practice totally. Thereby it can be recommended that active behavior-changing communication is required for all sections of the society to tear out the social root of the problem instead of unimpressive vague health warnings in vogue.

A clinico epidemiological study on acute viral infection of brain among children admitted in North Bengal Medical College, West Bengal.

A clinico epidemiological prospective study was carried out on acute viral infection of brain among children admitted in a rural based medical college from September '99 to Oct '01. Out of 80 cases, 8 cases (10%) of aseptic meningitis, 35 cases (43.75%) of encephalitis and 37 cases (6.25%) of meningo-encephalitis were found. Overall case fatality was 47.5% and found higher (77%) among normally nourished children in comparison to malnourished children (47.5%). Virological investigation did not isolate any known Flavivirus, Herpes Simplex virus (HSV) and Measles virus; nor any serological evidence against these viruses.

Iodine deficiency disorders among school children of Dakshin Dinajpur District, West Bengal.

Iodine deficiency disorders (IDD) are major public health problems in India, including West Bengal. Existing programme to control IDD needs to be continuously monitored through recommended methods and indicators. Thus we undertook the study to assess the prevalence of goiter, status of urinary iodine excretion (UIE) level and to estimate iodine content of salts at the household level in Dakshin Dinajpur district, West Bengal. We conducted a community-based, cross-sectional study in 2004; among 2250 school children, aged 8-10 years. The '30 cluster' sampling methodology and indicators for assessment of IDD, as recommended by the joint WHO/UNICEF/ICCIDD consultation, were used for the study. Goitre was assessed by standard palpation technique, UIE was analyzed by wet digestion method and salt samples were tested by spot iodine testing kit. Of the 2250 children, 419 (18.6%) had goitre (95% CI = 17.0 - 20.2%). Total goitre rate (TGR) was not significantly different in respect of gender, age and religion. Visible goitre rate was 2.5%. Median urinary iodine excretion level was 16 mcg/dL (normal: > or = 10 mcg/dl.) and 16.5% children had value less than 5 mcg/dL. Only 67.4% of the salt samples tested had adequate iodine content of > or = 15 ppm, with significant difference between Hindus and Muslims (chi2 = 12.68, d.f. = 1, p < 0.01). TGR of 18.6% indicate the district is still endemic for IDD, but median urinary iodine within normal range reflects no current iodine deficiency. The district is in the transition phase from iodine-deficient to iodine-sufficient. Measures are to be sustained for successful transition towards elimination.

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.

Rural people and fine needle aspiration cytology (FNAC)--some findings in North Bengal Medical College, Darjeeling, West Bengal.

A hospital based interdepartmental collaborative study was carried out from 1st July to 30th September, 2000 on 269 rural people residing in six districts of the northern part of West Bengal and attending the Pathology Department in North Bengal Medical College for Fine Needle Aspiration Cytology (FNAC) after being referred from different clinical departments. The objectives of the study were to study some aspects of the outcomes of FNAC among rural people and to suggest for its wider application in rural community through Community Health Centre/Rural Hospital/Block Primary Health Centre. The results shows that Hindus (80.3%) are attending more in number than Muslims (14.13%), Christians (4.83%) and Buddhist (0.74%); 53.54% of the population are in 11-40 years age group. In benign conditions 76.95% are coming from up to 100 kms. of N.B.M.C; people in lower per capita income group of up to Rs.400/- per month are attending twice in number than those in the income groups of Rs.401/- and more per month. In malignancy however people do not think of distance or expenses due to seriousness of the diseases. In 14.5% cases FNAC remains inconclusive whereas in 85.5% cases it provides definite diagnoses.

Perception and practice regarding pulse polio immunisation in an urban community of Calcutta.

A survey was conducted at an Integrated Child Development Services (ICDS) Scheme project in North Calcutta among 656 mothers having children less than 3 years of age to assess their perception and practice regarding pulse polio immunisation (PPI). It was revealed that 91.8% of under 3-year children received PPI on 9-12-1995 and 94.4% on 20-1-1996. Major reasons for not accepting the services on those two days included 'mothers unaware' (22%), 'child too small' (30.5%), etc. Major source of first information was television (TV)/radio (57.2%) followed by anganwadi workers (AWWs) (33.8%). However, majority of the mothers were finally motivated for PPI by AWWs (58.8%) followed by the role of TV/radio (34.1%). Although 70.7% mothers knew the name of the vaccine correctly, only 3.5% mothers could tell the exact purpose of its administration. Most mothers (73%) opined that 2 drops of oral polio vaccine (OPV) was administered to their children and only 14.6% hoped that such programmes will be conducted by the Government in future. The average waiting time of mothers at immunisation centres was found to be 7.2 minutes.
