ABSTRACT
Pulmonary Function Tests (PFT) of 45 swimmers who swam a distance of 2 to 5 kms per day regularly were compared with age, sex, height and weight matched controls. VC, IRV, FVC, FEV1 and V25 were higher in swimmers (S) than controls (NS) by 20%, 25%, 37.4%, 30.1% and 15.1% respectively. The effect of the period of training on PFT's was also analysed. Inspiratory capacity was significantly higher in Gr IS than NS probably due to a reduction in FRC, FVC and FEV1 were higher in Gr. II than NS. Greater differences were seen between Gr. IV S and NS, where FVC, FEV1, V75 and PEFR were higher by 50.2%, 38.2%, 69.4% and 25% respectively in the S than NS. Probably the first parameter to increase is IC. The greater differences in PFT values of Gr. IV S and NS may be due to hypertrophy of the diaphragm which requires hard work for prolong period. Further longitudinal studies are needed to confirm these observations.

Thirty-one boys between the ages of 9 and 17 years were subjected to submaximal exercise stress testing on a treadmill using the Bruce's protocol. All the children completed the test with the younger group (9-13) reaching Grade III and the older group boys (14-17) reaching Grade IV on an average. The heart rate, blood pressure and FEV1 during exercise compared well with other reported studies. On ECG analysis there were no significant ST segment changes or J junction depression. This study was conducted in well nourished boys from high-socio-economic group who regularly took part in sports.

Cryptosporidium is an intestinal protozoa known to cause diarrhea in animals and more recently has been recognised as a cause of diarrhea in humans. The present study was designed to determine the prevalence of cryptosporidium as a cause of diarrhea in children. Faecal samples of 180 children admitted to the hospital for acute gastroenteritis and from 100 normal children were analysed. Eight out of 180 (4.4%) stools from children with acute diarrhea and none from normal showed cryptosporidi. We conclude that this parasite does play a role in the etiology of human diarrhea.

An open trial of Ketotifen was conducted on 29 children suffering from asthma of varying duration. The drug was given orally in a dose of 1 mg twice a day. Children were followed up weekly for a period of 3 months. It was found beneficial (though the benefit was not statistically significant) in children having asthma of less than 2 years duration who were taking one drug regularly or were on occasional treatment. There was marginal effect in children taking salbutamol and theophylline together, but irregularly and no benefit in children taking prednisolone.
