Article Synopsis
- Octylisothiazolinone (OIT) is a biocide used in leather products, raising concerns about allergic reactions, particularly in headphones.
- A study reported cases of allergic contact dermatitis (ACD) in patients linked to headphones containing OIT, confirming its strong allergic potential through patch testing and chemical analysis.
- The findings suggest that OIT is a significant sensitizer and highlight the need for safer use guidelines and improved product labeling in the leather industry to protect consumers.
Background: Limited and conflicting data have been reported on the impact of dupilumab (DUPI) on patch test (PT) results and its efficacy against allergic contact dermatitis (ACD).
Objective: This study was undertaken to analyze PT reactivities and relevance during treatment with DUPI to determine whether they could detect ACD in patients with uncontrolled or worsened atopic dermatitis (AD) who were receiving this agent.
Methods: This prospective, multicenter study examined 76 DUPI-treated patients who had undergone PTs.
Objective: To analyse the clinical characteristics and sensitivity of an essential oil patch test series (EOS) in patients sensitized to their own essential oils (EOs).
Method: We analysed the clinical data and patch test results obtained with the European baseline series (BSE) and an EOS, as well as the mode of use of EOs, through a questionnaire included in the patient file.
Results: The study included 42 patients (79% women, average age 50 years) with allergic contact dermatitis (ACD), 8 patients required hospitalization.

Contact Dermatitis
September 2023
Background: Allergic contact dermatitis to gloves is mostly induced by rubber accelerators. The European baseline series (EBS) appears insufficient to detect glove allergy. Since 2017, it is recommended to use the European rubber series (ERS) and to test the patients' own gloves.
View Article and Find Full Text PDFBackground And Objectives: The repeated open application test (ROAT) is an adjuvant investigation measure to patch testing in the diagnosis of allergic contact dermatitis. ESCD recommends a 15 days duration but its overall duration varies according to publications and patients hardly adhere to prolonged ROAT duration beyond 1 week.
Materials And Methods: The Dermatology and Allergy Group of the French Society of Dermatology performed a prospective study with the aim of determining the best duration for the ROAT.
