ABSTRACT

OBJECTIVE: To determine the extent, epidemiological and clinical features of an epidemic of non-inflammatory encephalopathy in northern region of India. DESIGN: Surveillance of referred cases having unconsciousness after a short bout of fever during October and November 1997. Case control study in 7 most affected villages. METHODS: Active case finding was done to assess the extent and severity of the epidemic by interviewing health professionals and by reviewing mortality records in 10 districts of Haryana, Punjab and Chandigarh. A house to house survey was conducted in seven most affected villages. A case was defined as any child of less than 15 years of age, who had prodromal fever followed by vomiting and unconsciousness with subsequent recovery or death. Two age and sex matched controls who had fever without unconsciousness were taken for each case, one from nearby house and another staying furthest from the affected house. These groups were compared for various epidemiologic factors, clinical features and treatment pattern. Residual medicines used by affected patients were tested for presence of salicylate. Local village practitioners were interviewed for their knowledge and attitude towards use of aspirin in a febrile child. RESULTS: Information regarding 129 affected children (M: F=1 : 1) could be obtained. Age ranged between 1 to 12 years (mean 5.8 years). Most were from rural or semi-suburban areas. Attack rate was 5.4/1000 and case fatality rate was 72%. Multiple sibs were affected in 9.3%. History of fever was reported by 83%, vomiting preceding unconsciousness by 83% and abnormal behavior by 65%. Abnormal posturing was reported in 55%. Seventeen (61%) of 28 samples had IgM antibodies in serum/CSF against measles. Twelve (36%) of 33 serum samples tested positive for Varicella zoster virus. None gave history of aspirin intake and 10 samples of residual drugs did not contain salicylate. However, 6 out of 19 blood samples taken from affected patients contained salicylate. Environmental factors were in favor of Japanese encephalitis (JE) but brain biopsy and serology disproved it. Based on earlier report of JE from this area, the cases in present epidemic were being reported as JE before this study was undertaken. Intensive fogging with malathion was being undertaken as antimosquito measure, specially around the affected houses. Local village practitioners (n = 37) were unaware of contraindications of aspirin in a febrile child. CONCLUSION: Measles and varicella zoster emerged as the probable etiologies for the viral prodrome precipitating these cases of Reye's syndrome. Aspirin might have a contributory role. Malathion is another putative cofactor.

ABSTRACT

Developing countries are going through a demographic transition. Non-communicable diseases like hypertension are emerging in epidemic proportions. Education and awareness among people is the key to reduce the burden of the disease. To see the levels of awareness and characteristic of aware and unaware hypertensives, 7630 employees in Shimla town were screened for hypertension. Hypertension was detected in 2535 cases of which 559 (22.05%) were aware. The aware hypertensives were predominantly symptomatic and had higher age and blood pressure than the unaware hypertensives. The aware hypertensives were predominantly overweight. This low level of awareness highlights the need for a comprehensive hypertension education programme to be taken up at the national level.

ABSTRACT

A random survey for determining the prevalence of NIDDM was conducted in the population aged 40 years and above of Shimla town. 1195 subjects were screened for estimation of NIDDM prevalence from seven randomly selected wards. The prevalence of NIDDM in age group 40 years and above was 4.86% (5.17% in males and 4.38% in females). NIDDM was found to be positively associated with increasing age, BMI, WHR, family history of diabetes and negatively with physical activity. Stress should be on early detection of diabetes to reduce the heavy burden of morbidity and mortality caused by diabetes.

ABSTRACT

A cross sectional study was carried out to assess immunisation coverage among 257 urban and 339 rural children aged 13-36 months who were vaccinated at pulse polio booths in Shimla hills. 84.37% urban children and 57.59% rural children were fully vaccinated. BCG scar was negative in a large number of children, especially from rural areas. Increasing maternal education was associated with complete immunisation. OPV I-III dropouts were 3% among urban children and 15% among rural. The corresponding dropout rates for DPT I-III were 1% and 8% respectively. The immunisation coverage in this region was higher than others. Sustained efforts are required to achieve full immunisation coverage and eradicate polio and measles.

ABSTRACT

A cross sectional study of 398 mothers and infants was conducted to assess the age at first breast feeding, and its determinants, in Shimla. We found that the timely first suckling rate was 0.10 in urban group and 0.11 in rural group. The median age at initiation of breast feeding was five hours among urban cases and four hours among rural cases. Most of the infants were breast fed by the age of 24 hours which is a positive sign and is higher than previous studies. Absence of definite trend vs mother's education may be due to other factors. A community-based educational programme to promote early breast feeding is required, along with training on lactation management counselling for health workers. This will help in achieving healthy child development through prevention of childhood malnutrition.

ABSTRACT

A cross sectional study of 888 randomly selected subjects in Shimla town was done to determine prevalence of obesity, its relation to age and physical activity. The prevalence of obesity was 21.5% using cut off levels of BMI 25. The prevalence of obesity rose significantly with age. Obesity was less in those having moderate physical activity as compared to those with low and high activity. Primary prevention is required to tackle this disease risk factor through health education focussing on promotion of moderate regular physical activity.
