Abstract
India is among the most densely populated countries of the world and it is undergoing rapid urbanization and economic changes and simultaneously the prevalence of asthma and allergies are increasing. Similar trends have been observed in other developing countries. In this context the study by Raj, et al. [1] on aeroallergen sensitization in childhood asthmatics in northern India is significantly important. In this study, the skin prick test (SPT) was performed on 180 children and very exciting results were obtained; close to 44% of the children were negative for atopy and in remaining 56% interesting pattern of sensitization was observed which appears to be unique to north India. This paper reestablishes the utility of the SPT.
