Thumb-Sucking, Nail-Biting, and Atopic Sensitization, Asthma, and Hay Fever

Abstract

an increased diagnosis of atopic dermatitis (P 5 .007). The majority of these atopic dermatitis patients with positive results from SPTs at 1 year of age were sensitized to food (91.6%), most commonly eggs (83%). CONCLUSIONS. There is poor agreement between the results of SPTs and SSIgE tests in early childhood, particularly in testing for sensitivity to food allergens and in testing at a younger age; therefore, these 2 tests cannot be used interchangeably. At least 1 SPT with positive results for sensitivity to an aeroallergen or food allergen at 1 year of age was predictive of the occurrence of atopic dermatitis during the follow-up period lasting up to 6 years of age. REVIEWER COMMENTS. This birth cohort study is unique in that it evaluates for consistency between the results of SPTs and SSIgE levels over time in the early childhood population. Exploration in a more diverse population that is not limited to the rural setting and in a larger cohort would be beneficial because a low number of subjects in this study had positive SPT results. The poor correlation between SPT and SSIgE test results seen in this study provides additional insight regarding the development and natural course of sensitization in early childhood and suggests that correlation with clinical outcomes remains essential.

“…A chronic habit of nail biting or finger sucking causes dry and peeling skin and leads to inflammation of the skin surrounding the nail [8]. Plenty of unpalatable herbs grown throughout Southern and Southeastern Asia exhibited various biological effects, especially antioxidant and antiinflammatory activities.…”
