Article Synopsis
  • Fragrances are prevalent in many everyday products, including perfumes and air fresheners, and can also be found in unexpected sources like workplaces, often hidden even in "fragrance free" items.
  • Allergic contact dermatitis (ACD) caused by fragrances is a common issue, emphasizing the need for both patients and healthcare providers to be informed about it for effective management.
  • This review highlights the chemistry and prevalence of fragrance-related ACD, provides guidance on patch testing, and stresses the importance of educating patients on avoiding triggers to improve treatment success.

Identification of athletic shoes for patients with contact allergy is difficult. Company reports of allergen content are often incorrect. To determine whether chemical analysis of 4 athletic shoes, previously reported to be free of the most common contact allergens, contain quantifiable allergen levels.

Although allergic contact dermatitis is a type IV hypersensitivity reaction, type I hypersensitivity reactions, such as anaphylaxis, have been reported during patch testing. The aim of this study was to identify reported cases of anaphylaxis from patch testing and estimate its rate. A literature review was conducted on PubMed to identify previously reported cases of anaphylaxis after patch testing and suspected allergens.

Consideration of contact allergen concomitant reactivity, which encompasses cross-reactors, co-reactors, and pseudo cross-reactors, is an important aspect of patient care, yet information on how these terms are differentiated and used in clinical practice is lacking. In this review, we provide definitions of cross-reactors, coreactors, and pseudo cross-reactors and discuss the utility of the American Contact Dermatitis Society Contact Allergen Management Program database cross-reactor groupings. We also discuss limitations to the current categorization of cross-reactivity and recommend incorporating new terms, including "apparent cross-reactor" and "derivative cross-reactor," when classifying cross-reactors.

Allergen avoidance is the most effective treatment of contact allergy. Patient improvement ultimately relies on identification of safe alternative products, which can be used by the patient. Safe personal care product options typically can be found using ingredient database programs.

Background: Product disclaimers listed on personal care products face limited regulation. These disclaimers may be helpful or may mislead the public.

Objective: Review the evidence supporting the potential harms of 3 compounds commonly addressed by product disclaimers: parabens, aluminum, and sulfates.

The American Contact Dermatitis Society Core Allergen series was introduced in 2013 and updated in 2017. Changes in our recommended allergens are again necessary, taking into account data from the American Contact Dermatitis Society's Contact Allergen Management Program top 100 allergens from 2018. For the updated series, we removed methyldibromoglutaronitrile and added new haptens: Lyral, Limonene, Linalool, carmine, benzyl salicylate, disperse yellow 3, jasmine, peppermint, pramoxine, shellac, and lauryl polyglucose (glucosides).

Background: The American Contact Dermatitis Society Contact Allergen Management Program (CAMP) database was developed to provide patients with safe alternative products free of selected contact allergens. However, the CAMP database also records valuable information including the frequency of contact allergen searches for patients.

Objectives: The aim of the study was to determine the relative prevalence of contact allergens in North America.

The year 2019 marks the 30th anniversary of the American Contact Dermatitis Society (ACDS). The work of inaugural ACDS members and the 3 decades of camaraderie, collaboration, education, and investigation of contact dermatitis that followed the inception of the ACDS are celebrated in this historical account.

Background: Surfactants are common ingredients in topical products, which can cause both irritant and allergic contact dermatitis.

Objective: The aim of this study was to determine the prevalence of 12 common groups of surfactants and 12 common individual surfactants among products in each category in the American Contact Dermatitis Society Contact Allergen Management Program (CAMP).

Methods: The American Contact Dermatitis Society CAMP was queried for the 12 surfactant groups and the 12 individual surfactants.

Propylene glycol (PG), an emollient and emulsifier found in cosmetics, medications, and food, has been granted the dubious honor of being named the American Contact Dermatitis Society's Allergen of the Year for 2018. Contact, systemic, and irritant cutaneous reactions have been documented for PG, which has become an increasingly common ingredient. Propylene glycol is as contentious as it is ubiquitous because it acts as both a weak sensitizer and an irritant, confounding the results of positive patch tests.

Background: Bimatoprost has known adnexal activity and was observed to increase nail growth at two clinical centers.

Objectives: In this randomized, double-blinded, placebo-controlled pilot study, we examine the effect of bimatoprost (Lumigan 0.01%), applied bid to the proximal nail fold on nail growth, nail brittleness, and intraocular pressure.
