Abstract
Background: Contact dermatitis in continuing to be increasingly recognized in pediatric populations, especially in those with
atopic dispositions. Exposures in children parallel those seen in adult populations. In fact, as post university career jobs are
becoming more difficult to acquire, in many countries youngsters are once again entering apprenticeships to obtain
immediate economic remuneration. These apprenticeships come with occupational exposures to allergens.
Objectives: To review the most common sensitizers in children and to evaluate the changing tendencies of occupational
dermatitis in children.
Patients/Materials/Methods: For 16 years, we patch tested 12,719 patients. Of these, 396 (3.11%) were children younger than
16 years old. All children were patch tested with the standard GEIDAC (Spanish Contact Dermatitis Group) test series, or
with the standard True-test series. In addition, some of them were tested with specific allergens with additional supplemental
allergens as warranted by history
Results: Among these 396 patch tested children, 119 (30%) were positive to one or more allergens, 73 girls (61%) and 46 boys
(39%). The most common allergens were nickel sulfate, cobalt chloride and mercury ammonium chloride. A second group
Additional top allergens included the components of rubber accelerators, potassium dichromate, fragrance mix and 4
phenylenediamine base, para-tertiary butylphenol (PTBP) formaldehyde and isothiazolinone, wool alcohols, Myroxylon
pereirae. colophony, colophonium [if you are going to use INCI names for M.p. would be consistent] formaldehyde and N
isopropylphenyl- paraphenylenediamine (IPPD).
