Clinico-bacteriological study was done in 51 leprosy patients below 14 years of
age. Majority of the patients were males in the age group of 11-14 years. Nearly 84% had not received any prior treatment because of
lack of awareness and financial constraints. Only 11.76% had a positive contact
history. Skin lesions were present in all cases and 84.3% had lesions mainly on
the exposed areas of the body and their number was found to increase significantly
with advancing age (p < 0.005). These lesions were hypo-pigmented
patches in 88% cases. 88% of cases had hypo-anesthesia and nerve thickening was
observed in 24% cases. The most common type of skin lesion was borderline tuberculoid (BT) in 53% cases.
Positivity of the skin smears increased significantly as the number of the skin
lesions per patient increased (p < 0.001). Multibacillary cases were seen
in 15.6% of cases and found only in the age group of 10-14 years of age. No statistically significant
association between BCG vaccination and prevention of leprosy was seen.
We have carried out micro-canonical Monte Carlosimulations of a planar rotator model in 30 × 30 lattice using periodic boundary conditions. The energy distribution of the rotator in the lattice shows features that can be associated with spin wave and vortex excitations. The results supplement the first-order transition observed in canonicalMonte Carlosimulation, due to vortex nucleation. We also see features that can be associated with the in-homogeneity of vortex charge in the critical region.
