Childhood leprosy in eastern Nepal: a hospital-based study.

A hospital-based retrospective study on childhood leprosy was carried out at B.R. Koirala Institute of Health Sciences, Dharan, covering the period April 1998-April 2002. 20 (4.45%) leprosy patients were detected in children aged 6-14 years. The male:female ratio was 4:1. History of contact was found in 10% of the patients. The commonest type of leprosy was borderline tuberculoid leprosy (550%), followed by borderline lepromatous leprosy (301%). Most of the patients had more than one lesion. Nerve involvement and grade 2 deformity were noted in 55% and 20% of the patients respectively. Slit skin smear was positive in 30% of patients.

Titrimetric determination of ascorbic acid using chloranil.

Ascorbic acid is oxidized and quantitatively titrated with chloranil (2,3,5,6-tetrachloro-1,4-benzoquinone) in the presence of hexamethylenetetramine in acetone-water; the end point is determined visually by the appearance of a golden yellow color. Colored solutions are assayed by setting the initial absorbance at 451 nm to zero or the minimum, titrating with chloranil solution, and measuring absorbance after each increment of titrant. A plot of the volume of chloranil added against the absorbance gives a straight line with the volume intercept as the end point. Interference by the thiol group of cysteine, glutathione, etc., is avoided by masking with acrylamide; interference by iron(II) is masked with ammonium thiocyanate and sodium potassium tartrate. Hydrogen sulfite and thiourea (which do not interfere) are added as antioxidants during extraction of ascorbic acid from drugs and fruits.

Psychiatric morbidity in displaced leprosy patients.

One hundred confirmed leprosy patients, all of them migrated from elsewhere, were examined for psychiatric co-morbidity. Forty-six of them were from an 'ashram' and the others were from a slum area. 76% of the patients were found to be having psychiatric illness. Of these, 55% were having neurotic depression and 21% had anxiety neurosis. Single, unemployed, socio-economically backward and patients with physical deformities were suffering significantly more often with psychiatric symptoms. Psychiatric morbidity was found to be more frequent in the patients staying in slum than in those in the 'ashram' where they had some security.
