The Cutaneous Connection

In this episode of The Cutaneous Connection, Dermatology Times revisits a recent video episode of the Derm Dispatch show where host Renata Block, DMSc, MMS, PA-C, sits down with Zachary Rubin, MD — allergist, pediatrician, and New York Times bestselling author of All About Allergies — to explore the intersection of dermatology and allergy. Together, they tackle one of the most persistent myths in practice: that food elimination can treat atopic dermatitis.
Dr. Rubin breaks down the difference between IgE-mediated allergic reactions and the complex inflammatory nature of eczema, explains the atopic march, and discusses how understanding the gut-lung-skin axis can empower patients to take charge of their care. The conversation also covers the latest treatment advances — from JAK inhibitors to novel biologics — and touches on indolent systemic mastocytosis and the truth about so-called hypoallergenic dogs. A must-listen for any clinician treating allergic and inflammatory skin disease.

Join Dermatology Times for a conversation with Liza O'Dowd, MD, vice president of immunodermatology and respiratory disease areas at Johnson & Johnson, recorded at the 2026 AAD Annual Meeting. Dr. O'Dowd discusses one-year efficacy and safety data for icotrokinra (Icotyde), the newly approved once-daily oral peptide IL-23 receptor antagonist for moderate to severe plaque psoriasis in adults and adolescents 12 and older.
At 52 weeks, approximately 50% of adult patients achieved total skin clearance, rising to 60% in adolescents enrolled in the LEAD study. Adverse event rates through one year remained within 1.1% of placebo, with no mandatory tuberculosis pre-screening required. Dr. O'Dowd also addresses icotrokinra's anticipated role as a first-line systemic therapy and offers practical reassurance for clinicians considering this novel agent for their patients.

In this conversation, identical twin practitioners—dermatologist Amy Spizuoco, DO, FAOCD, and dentist Stacy Spizuoco, DDS,—discuss how dentistry and dermatology intersect in shared patients, from oral lesions and skin conditions to cosmetic collaborations that brighten and rejuvenate smiles “by the skin of your teeth.”

In this episode, we sat down with Doris Day, MD, a board-certified dermatologist in New York City, who's 25-year long career focuses on longevity aesthetics. She discussed the most common cutaneous concerns among menopausal women, insights from Galderma’s recent menopause survey, and how dermatologists can thoughtfully incorporate conversations about hormonal health into aesthetic consultations.
