A multicentre study of contact sensitization in children

The results of 7 months of patch testing with a standard series of 26 allergens in 323 children with eczematous conditions or itching palmoplantar psoriasis under the age of 14 years are reported 114 (35.3%) of the children had 1 or more positive reactions to this standard series 28 children (8.7%,) were polysensitive. On the basis of personal history, additional series of allergens and/or specific allergens were also tested 61.7%, (90/146) of positive reactions were considered relevant to the current dermatitis. Metals, medicaments, preservatives or fragrances and shoe components were the major sources of contact sensitization. It is suggested that patch testing be done more frequently in evaluating dermatitis in children.
