Abstract and Introduction Abstract Background: Few US studies have reported results of patch testing with plastics and glues.
Objective: To report our institution’s results of testing patients suspected of allergy to plastics and glues with a comprehensive plastics and glues series and to compare these results with previously published data.
Methods: Retrospective review of results of patch-testing with plastics and glues allergens at our institution between 2000 and 2007.
In total, 444 patients were patch-tested with up to 56 plastics and glues allergens in the specialized series and up to five plastics and glues allergens in a baseline series.
Positive-reaction rates were compared to other patch testing reports.
Results: Of patients, 97 (22%) had irritant reactions, and 201 (45%) had at least one allergic reaction.
Bis(2-dimethylaminoethyl) ether 1%, benzoyl peroxide 1%, epoxy resin, bisphenol F 0.
Testing with specialized series identified 193 patients with plastics and glues allergy, of whom 162 were not identified by testing with baseline series alone.
Conclusion: For patients suspected of allergy to plastics and glues, patch-testing with specialized series of plastics and glues allergens is an important adjunct to patch-testing with baseline series.
Introduction Plastics and Glues are macromolecular end products.
They are applied in a wide range of areas, including construction, packaging, electronics, recreation, and medicine.
Allergic contact dermatitis (ACD) from these materials is mostly attributed to nonpolymerized material that remains before the completion of a chemical reaction.
Therefore, most ACD from plastics and glues occurs in the occupational setting, especially in the manufacturing field.
Sources of non–occupation-related ACD include shoes and dental and medical devices such as dentures and hearing aids.
Plastics and glues can be classified into various categories, including epoxies, acrylics, polyurethanes, phenol-formaldehyde resins, and polyesters.
Although the medical literature describes the results of patch-testing with plastics and glues, information in the current literature is limited in regard to US rates of contact dermatitis from plastics and glues.
We present the results of patch-testing with plastics and glues at Mayo Clinic and compare them to results reported in the medical literature.Full Article
