ALLERGIC CONTACT-DERMATITIS FROM PARA-TERTIARY-BUTYLPHENOL-FORMALDEHYDE RESIN (PTBP-F-R) IN NORTHERN-IRELAND

Over the past 5 years, 2270 patients with suspected allergic contact d ermatitis were patch tested in our clinic to the European standard ser ies of allergens. 7 patients (0.3%) showed a positive reaction (greate r-than-or-equal-to +) to PTBP-F-R. In 3 (42.9%) of these patients, the allergen was traced to adhesives but no allergen source was determine d in the remainder (57.1%). On the basis of these findings, it is ques tionable whether PTBP-F-R alone should routinely be included in the Eu ropean standard series.
