In our study the relative incidence of vitiligo among new patients was 2.6%. Twenty percent were children and 74% were adults. Of the 90 children, 38.9% were boys, and 61.1% were girls. This sex difference was statistically highly significant. The adult sex-ratio was not statistically significant. The relative incidence of the clinical subtypes in children and adults was compared, and the difference was found to be statistically highly significant only in the case of vitiligo vulgaris and segmental vitiligo. On the basis of the difference in the sex-ratio and in the relative incidence of the subtypes of vitiligo vulgaris and segmental vitiligo, we feel that childhood vitiligo is a distinct subtype of vitiligo.

Our study objective was to determine the prevalence and pattern of sexually transmitted diseases (STDs) and to study sexual lifestyles of long-distance truck drivers and their assistants in south India. For this, a total of 263 truck drivers/assistants were recruited from the highway clinic from October 1999 to March 2001. All of them were sexually active and heterosexual contact was the predominant mode (99.2%). Two-thirds of them had contact with commercial sex workers (CSWs) and roughly 60% admitted alcohol consumption. One hundred and two participants (38.7%) had various STDs. The positivity rates of HIV, VDRL and HBsAg were 15.9%, 13.3% and 21.2% respectively. The higher median age, education less than primary school level, longer duration of occupation, longer duration of each trip and a previous history of genital ulcer disease were significant risk factors for the acquisition of HIV infection.

Two cases of longstanding rhinosporidiosis developed widespread asymptomatic nodular skin lesions. Cutaneous examination showed multiple, discrete, sessile and pedunculated, smooth and warty, friable nodular lesions of variable sizes and shapes. Histopathology of representative skin lesions showed hyperplastic epidermis with sporangia containing spores in the upper dermis diagnostic of rhinosporidiosis. Epidemiological data about rhinosporidiosis at Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, India, is presented. Possible modes of dissemination to the skin and differential diagnosis are discussed in relation to this rare manifestation of rhinosporidiosis.

Although both the procedures are effective in lip vitiligo, PSG gives a better color match than SBEG.
