In Episode 6 of Derms and Conditions, host James Del Rosso, DO sits down with Matthew Zirwas, MD to talk facts and fiction in the world of allergic contact dermatitis.

In this episode, James Del Rosso, DO talks to Matthew Zirwas, MD about some very practical pearls for prevention, clinical diagnosis, and management of contact dermatitis, especially in the absence of patch testing. Drs. Del Rosso and Zirwas discuss the origins of latex allergies and clinical patterns to recognize in hand, scalp, and face dermatitis, as well as some of Dr. Zirwas' favorite products for sensitive skin, including gloves for patients and medical professionals, deodorants, antiperspirants, hair coloring, and soaps.

Practical Tips on Contact Dermatitis from the Heartland of America

Contact Dermatitis Update for 2025

Kicking off the first day of lectures in Miami, David Cohen, MD, MPH, provided an insightful overview of contact dermatitis, focusing on allergens dermatologists should monitor in 2025. He highlighted shifting trends, noting that while nickel and methylisothiazolinone (MI) remained the top 2 allergens, fragrance mix components like hydroperoxides of linalool and benzisothiazolinone (BIT) moved up the rankings. Through patient case studies, Dr Cohen explored common offenders such as MI, lanolin, and fragrance, emphasizing the rising prevalence of MI sensitization, which increased from 2.5% in 2010 to 13.8% in 2023. Despite being a common test allergen, MI testing may miss up to 60% of BIT sensitizations, prompting the need for broader testing strategies. Lanolin, designated as the 2023 allergen-of-the-year and commonly manifesting as contact dermatitis on the lips or genitals, was noted to be more likely seen in patients with concurrent atopic dermatitis. Fragrance sensitivity was also prevalent, with nearly 1 in 4 patients with contact dermatitis reacting to allergens like hydroperoxides of linalool and limonene, which require specific inclusion in patch test panels.Dr Cohen also addressed systemic contact dermatitis, a condition triggered by systemic exposure to allergens and often misdiagnosed due to its varied presentations, such as baboon syndrome or dyshidrotic hand eczema. He concluded with a focus on sulfites, the 2024 allergen-of-the-year, found in cosmetics, food, beverages, and pharmaceuticals, including topical antifungals and local anesthetics. By emphasizing the importance of recognizing new trends, refining diagnostic tools, and expanding patch test panels, Dr Cohen underscored the evolving landscape of allergen detection and management in dermatology.

Dermbusters: Daniel Butler, MD

In this episode of Dermbusters, our host, Nicholas Brownstone, MD, chats with Daniel Butler, MD, to discuss how he counsels patients who come to him with some common misperceptions dermatologists often hear. In this installment, Dr Butler addresses myths on scalp massage for baldness and contact dermatitis arising from deodorant use.&nbsp;<h5>Can scalp massage help prevent baldness?&nbsp;</h5>One common misperception dermatologists often hear from their patients is the belief that increasing blood flow to the scalp via scalp massage can prevent baldness.&nbsp;Dr Butler advises patients on the complexity of hair growth, emphasizing that just increasing blood flow to the scalp is not a cure-all for hair loss.&nbsp;He notes that there are some small studies that suggest scalp massage may marginally increase hair thickness; however, he clarifies that this does not equate to a viable solution for those with androgenic alopecia.&nbsp;<h5>Can deodorant cause contact dermatitis?&nbsp;</h5>Another common query from patients is whether deodorant can trigger contact dermatitis. Dr Butler addresses this concern by acknowledging that certain deodorants can indeed lead to contact dermatitis, but he emphasizes the importance of ruling out other potential causes for rashes before attributing them solely to deodorant use.&nbsp;Importantly, he reassures patients who don’t have existing rashes that using deodorant or antiperspirant should not be a cause for concern.&nbsp;When we get rashes in the armpits, patients often question what’s touching them there that can cause it. Some deodorants have been known to cause contact dermatitis, but there are other things that need to be ruled out first and foremost. If you have a rash in that area, it’s important to know that deodorant can be contributing to that. However, if you don’t have a rash and you’re using a deodorant or antiperspirant, don’t worry that it will then cause contact dermatitis.
