Evaluation of parasitological and serological techniques in diagnosis of amoebiasis.

Parasitological investigations carried out on 324 subjects of symptomatic and asymptomatic amoebiasis showed that formol-ether concentration was a superior technique than examination of 3 consecutive stool specimens by direct microscopy in cases of colitis, hepatitis and cyst passers. Culture of pus yielded better results than the other techniques for examination of stool in cases of liver abscess. Indirect haemagglutination test carried out with 238 sera from cases confirmed to be either positive or negative for Entamoeba histolytica revealed good correlation of its results with parasitological investigations in cases of dysentery and hepatitis. This test proved to be much superior to parasitological investigations in diagnosis of liver abscess. A close correlation between the results of gel-diffusion and I.H.A. was observed in dysentery and liver abscess groups, although I.H.A. was more sensitive. Precipitin band appeared in gel-diffusion test only when the I.H.A. titre was 1: 486 and the number of bands increased with rise in the titre.

An unusual outbreak of hookworm disease in North India.

An unusual outbreak of hookworm disease occurred after a game of "kabaddi" (a local game which results in much body contact with the ground) in 27 young males from one village. It was characterized by an immediate incapacitating dermatitis, followed by severe pulmonary symptoms. Progressive weakness, abdominal pain, weight loss and anemia developed within a few months. Ancylostoma duodenale was found in all except four patients who had received antihelminthic treatment. Specific treatment for hookworm resulted in complete clinical recovery. Features of the outbreak were: 1) the hitherto unrecorded mode of infection; 2) severe dermatitis; 3) pulmonary symptoms lasting more than 3 mo; 4) abdominal symptoms suggestive of subacute obstruction starting 4-6 mo after exposure; and 5) severe disability with weight loss for a period of 1 yr until specific treatment was administered.

Effect of periodic deworming on nutritional status of ascaris-infested preschool children receiving supplementary food.

The weight for age of 154 undernourished preschool children in an ascaris-infested community receiving supplementary food was monitored for a year. 74 children were given tetramisole every 4 months, while 80 controls were given placebo. The prevalence of ascaris (roundworm) infection and the severity of protein-energy malnutrition were the same in the two groups at the onset of the study. Stool-positive rates for ascariasis came down significantly in the experimental group during the year, but eradication of the worm was not possible owing to constant re-exposure. Nutritional status remained unaltered in the controls but improved strikingly in the treated children 8 and 12 months after the start of the study. Periodic deworming should form a part of the supplementary feeding programme if malnutrition is associated with ascariasis in the community.

Pterygium and dry eye--a clinical correlation.

Schirmer's test and tear film break-up time (BUT) were studied in 56 eyes of patients with pterygium and compared with 50 eyes of normal healthy subjects representing the same age, sex and geographical distribution. Both the values were found to be significantly reduced in cases of pterygium indicating the inadequacy of tear film in these patients.
