Selenium is an important trace element for human health. Selenium levels in mothers may have significant effects on fetal and neonatal nutrition. In a cross-sectional study undertaken in Rohtak, Haryana, plasma selenium level in mothers was investigated at the time of delivery. The mean plasma selenium level in full term mothers (n=82) was 70.63 +/- 1.62 ppb and in preterm mothers (n = 58), it was 63.28 +/- 2.31 ppb. The difference was statistically significant (p < 0.05). These levels were, however, below the reported normal level of 75-120 ppb in adults. Rura/urban stay, parity, maternal age, socio-economic and literacy status etc. did not influence the selenium level of mothers in either of the groups.

Results of Thyroid function tests of 671 individuals have been studied. The analysis shows that T3 and T4 hormone tests are not efficacious as compared to TSH test (p < 0.001) and in diagnosing Hypothyroid cases T3 and T4 lead to almost same results while in detecting Hyperthyroid cases T3 is superior to T4 (p < 0.01).

In this epidemiological study, stool samples were collected from 256 study subjects selected from seven villages of Kanpur district, Uttar Pradesh, India. The average age of the study population was 21.6 years. The overall prevalence rate of hookworm infestation was found to be 34%. Men had significantly higher rate of infestation at all ages. Prevalence rates increased with ages as well. In addition, adult worms were collected from twelve subjects. All were identified as Ancylostoma duodenale.

The study was conducted on a sample of 250 tribal people of Manipur state, comprised of 125 from the urban valley population and 125 persons from rural tribals settled on hilly area at a higher altitude. The finding shows that knowledge regarding transmission of malaria, self protection and treatment seeking behaviour is still poor among the tribal communities of Manipur. However the urban tribals had better knowledge regarding diagnosis of malaria and prevention of mosquito breeding than their rural counterparts.

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.

By and large, biomedical research is not a priority sector in south Asian countries, land of world's one-fifth population. The total number of studies published during 1990-98 from each of the south Asian countries were elicited based on MEDLINE database. The number of studies were normalised by population and physician size, and gross domestic products. The results showed that the following countries are more productive: India and Sri Lanka, when publications were normalised to population; India, Sri Lanka and Nepal when normalised to GDP; Nepal and Sri Lanka when normalised to physician number.

Anthropometry and morbidity profile of fifty randomly selected workers of coal handling plant at a thermal power station of West Bengal having at least five years experience were studied. The mean value of their age, duration of present job and Body Mass Index (BMI) were 34.8 years, 7.86 years and 19.24 respectively. As they were exposed to coal dust (Av. concentration 300-350 mg/M3 of air), warmth (Ambient temperature 40 +/- 5 degrees C), humidity (Relative humidity 80 +/- 5%) and noise [Av. 80 dB(A)], respiratory system was most commonly (72%) effected followed by greying of hair (5.6%), Cloth dusters used by some could not render any discernable protective effect. Addiction was also prevent (62%). Use of proper protective equipments (PPE) supplemented by adequate preplacement and periodic medical examination followed by successful rehabilitation were suggested.
