Patch testing book

Patch Testing 5th Edition

The full text of Anton de Groot’s well-known book Patch Testing (5th edition, 2022) is available to all members of the Society. A big thank you from The Executive Committee goes out to Dr de Groot for his generous donation of the book.

How to inform patients

The ESCD has written patient information leaflets for allergens within the baseline series. They were designed to be provided to patients at the time of consultation so that the applicability of advice and relevance can be tailored to the individual by their physician.

Contact Dermatitis
Journal

The Journal Contact Dermatitis is the official journal of the ESCD. It publishes scientific discoveries in the field of cutaneous allergy, environmental and occupational dermatitis, including chemical aspects, immunology, and drug reactions. Its impact factor is (2023): 4.8

๐ŸŽง Severe Allergic Reactions from Everyday Tech?

A striking case series led by Marion Menanteau and colleagues, published in Contact Dermatitis, highlights severe allergic contact dermatitis (ACD) linked to octylisothiazolinone (OIT) in over-ear headphones.

๐Ÿงช OITโ€”used as a biocide in leatherโ€”was found in high concentrations in ear pads, triggering strong allergic responses, including one case initially misdiagnosed as angioedema.

๐Ÿ“ข This study raises urgent questions about regulation and labelling of non-cosmetic consumer products.

๐ŸงŠ New study highlights hand eczema in the Arctic

A population-based study in Tasiilaq, East Greenland, found a 22.4% point prevalence of hand eczema among adultsโ€”comparable to Nordic countries. Led by Morten Bahrt Haulrig and team, this is the first clinical skin disease study of its kind in an Inuit population.

๐Ÿ” Most affected individuals were female, exposed to wet work, and reported chronic symptoms.

๐Ÿ” New publication alert: Composition of Brazilian and Chinese Propolis for Patch Testing

๐Ÿ”ฌ The compositions of Brazilian propolis and 2 samples of Chinese propolis used for patch testing were analysed with gas chromatographyโ€“mass spectrometry/flame ionisation detection (GCโ€“MS/FID) of volatile components obtained by headspace SPME (solid phase microextraction).

๐Ÿ’ก The ingredients of Brazilian and Chinese propolis were quite different.

The study is available open access via: lnkd.in/er55axWy

๐Ÿ”ฌ Hexyl Resorcinol: A New Allergen in Depigmenting Products?

A recent case report by Cille Van Echelpoel and colleagues, published in Contact Dermatitis, describes two cases of allergic contact dermatitis (ACD) caused by hexyl resorcinol, a depigmenting agent found in cosmetic skincare.

โš ๏ธ Key Findings:

โœ”๏ธ Two women (ages 62 & 21) developed facial and neck eczema after using depigmenting products containing hexyl resorcinol.

โœ”๏ธ Patch testing confirmed a strong allergic reaction to hexyl resorcinol, while other resorcinol derivatives remained negative.

โœ”๏ธ This is the first report of hexyl resorcinol-induced ACD, adding to the list of emerging cosmetic allergens.

๐Ÿ’ก Why it matters:

โžก๏ธ Hexyl resorcinol is widely used in skin-brightening products, yet its potential as a sensitizer has been underreported.

โžก๏ธ The findings emphasize the need for dermatologists to consider this allergen in cases of unexplained facial dermatitis.

โžก๏ธ More research is required to assess its cross-reactivity and prevalence in allergic patients.

New Research on Hair Dye Use and Skin Reactions in the Dutch Population

Hair dye is widely used, but how common are skin reactions? A recent study led by Fieke M. Rosenberg and colleagues, published in Contact Dermatitis, sheds light on the prevalence of hair dye use and associated adverse skin reactions in the Dutch general population.

๐Ÿ”ฌ Key Findings:
โœ”๏ธ 63.1% of surveyed individuals reported using hair dye in their lifetime.
โœ”๏ธ 6.8% experienced skin reactions, mostly mild but occasionally severe.
โœ”๏ธ Women, middle-aged individuals, and those with a history of black henna tattoos were more likely to experience reactions.
โœ”๏ธ Hairdressers and beauticians had a higher likelihood of both using hair dye and experiencing adverse reactions.

โš ๏ธ The study highlights the need for greater awareness of potential allergic reactions and the importance of patch testing before use.

๐Ÿ“ก Allergic Reactions to Glucose Sensors & Insulin Pumps โ€“ A Growing Concern! ๐Ÿ“ก
A new review by Anton de Groot et al. highlights the increasing reports of allergic contact dermatitis (ACD) caused by glucose sensors and insulin pumps in patients with type 1 diabetes. The study discusses:
๐Ÿ”น The role of isobornyl acrylate and other allergens in causing skin reactions
๐Ÿ”น Challenges in diagnosing ACD due to lack of transparency from manufacturers
๐Ÿ”น Strategies for management and prevention, including proposed regulations
With diabetes devices improving glucose control, addressing these allergic reactions is crucial for patient safety and quality of life.

๐Ÿšจ New Research Alert! ๐Ÿšจ

Exciting work by Aaron Isaac Moore and colleagues, published in Contact Dermatitis, takes a "lipidomic approach" to understanding how fragrance hydroperoxides affect keratinocytes. ๐Ÿงช๐Ÿงด

The study focuses on limonene and linalool hydroperoxides, common fragrance allergens, and their impact on the lipid profile of skin cells. The findings provide critical insights into oxidative stress, inflammation, and potential mechanisms of skin sensitizationโ€”important for dermatology, cosmetics, and skincare science.
