"The same medication, the same dose—but given at bedtime improved efficacy by 150%."

Does the timing of a medication influence how well it works?

In this episode of JCMS Author Interviews, Dr. Kirk Barber speaks with Dr. Elena Netchiporouk, Assistant Professor of Medicine at McGill University and attending dermatologist at the McGill University Health Centre, about the emerging science of chronotherapeutics.

Dr. Netchiporouk explains how the body's circadian rhythms influence inflammation, immune responses, skin barrier repair, and wound healing. She discusses evidence suggesting that timing therapies to coincide with these biological cycles may improve treatment outcomes for inflammatory skin diseases, including atopic dermatitis, psoriasis, and chronic spontaneous urticaria.

The conversation explores practical implications for commonly used therapies such as methotrexate, cyclosporine, JAK inhibitors, and topical corticosteroids, while highlighting an exciting and underexplored area of dermatology that may help clinicians optimize both efficacy and tolerability.

“Most dermatologists hate to see these patients. But we must not hate to see them because they need help—and they need the dermatologist.”

— Dr. Marcelo Nico

In this 100th episode of JCMS Author Interviews, host Dr. Kirk Barber reflects on a milestone for the podcast before welcoming Dr. Marcelo Nico, Associate Professor of Dermatology at the University of São Paulo and a leading expert in psychodermatology.

Over the past 100 episodes, JCMS Author Interviews has connected listeners with authors, researchers, and clinicians from around the world, bringing the pages of the Journal of Cutaneous Medicine and Surgery to life through conversations that advance dermatologic knowledge and patient care. Kirk and his team are proud of the community that has built up around the podcast and want to send a specials thank you to everyone involved, especially our guests and you, our listeners.

Dr. Nico joins the podcast to discuss his article, “Dermatitis Artefacta: A Study of 42 Patients With Management Considerations.” Drawing on decades of clinical experience, he explains why dermatitis artefacta should be viewed as a distinct clinical diagnosis rather than a diagnosis of exclusion, and shares his compassionate approach to caring for patients whose skin disease is intertwined with underlying psychiatric illness.

The conversation explores the importance of trust, long-term follow-up, and recognizing the role of insight in psychodermatologic disorders. Along the way, Dr. Nico offers practical lessons for clinicians navigating some of dermatology’s most challenging patient encounters.

Dr. Marcelo Nico is Associate Professor of Dermatology at the Medical School of the University of São Paulo in Brazil. His work focuses on inflammatory and autoimmune skin diseases, oral mucosal disorders, and psychodermatology.

How can dermatologists better understand—and improve—the lived experience of patients with vulvar disease?

In this episode of JCMS Author Interviews, Dr. Kirk Barber speaks with Dr. Marlene Dytoc about her article, Evaluating the Impact of the Vulvar Quality of Life Index for New Patient Dermatology Assessments, in the Jan/Feb 2026 issue of the JCMS. Together, they explore how the Vulvar Quality of Life Index (VQLI) helps capture the often-overlooked burden of vulvar conditions and can strengthen communication between physicians and patients.

The conversation also highlights the surprising impact of expert-led virtual support groups for patients with lichen sclerosus. Dr. Dytoc discusses how peer support, education, and structured quality-of-life assessments can improve patient confidence, satisfaction, and disease management—often after just a single session.

Looking ahead, she shares new research examining diagnostic delays in lichen sclerosus and the factors that may contribute to missed or delayed diagnoses, including stigma, examination gaps, and limited awareness among both patients and clinicians.

Pediatric hand eczema is more common than we think — and it’s not simply “adult hand eczema in smaller hands.”

In this episode, Dr. Kirk Barber sits down with Dr. Sonja Molin to explore why pediatric hand eczema deserves its own clinical lens. From COVID-era handwashing to slime exposure, allergic contact dermatitis, and patch testing strategies, this conversation unpacks the real-world triggers affecting children today — and how to manage them effectively.

They discuss practical treatment pearls, when to patch test, steroid strategy, non-steroidal options, emerging topical JAK data, and how to empower kids and parents in long-term skin care management.

If you treat eczema — or live with it — this episode delivers clinical insight with heart.

This conversation centers on Dr. Molin's article in the July/Aug Issue of the Journal of Cutaneous Medicine and Surgery: Patterns of Pediatric Chronic Hand Eczema: A Systematic Review With Focus on Causes and Management.

Her co-authors are: Dr. Katie Yeung, Dr. Joshua Lowe, Dr. Jessica Ho.
