Send us Fan Mail Alopecia Boot Camp: Scarring vs Non-Scarring, Key Patterns, Dermoscopy Pearls, and First-Line Management | The Derm Resident Contact: [email protected] Hosts Dr. Jonny Hatch and Dr. Deven Curtis present an “alopecia boot camp” framework focused on first distinguishing scarring (cicatricial) from non-scarring alopecia by assessing follicular ostia with dermoscopy, emphasizing that scarring implies permanent loss and requires urgent treatment at the active edge for biopsy and intralesional therapy. They review non-scarring causes including androgenetic alopecia (DHT-driven miniaturization, anisotrichosis; Hamilton-Norwood/Ludwig scales; minoxidil, finasteride/dutasteride, spironolactone in women, PRP and transplant with donor dominance), alopecia areata (CD8 attack, exclamation point hairs, yellow/black dots; ILK and FDA-approved JAK inhibitors baricitinib and ritlecitinib; totalis/universalis/ophiasis), telogen effluvium (delayed shedding after stressors; hair pull test; consider TSH and iron studies/ferritin), traction alopecia (fringe sign; may become scarring), and trichotillomania (broken hairs of varying length). Scarring alopecias covered include LPP/FFA (perifollicular erythema and tubular scale; hydroxychloroquine/doxycycline and steroids), CCCA (central centrifugal pattern; biopsy active border; discuss styling factors and PADI3), and rapid-fire pearls for DLE (follicular plugging), folliculitis decalvans (tufting; clindamycin/rifampin), dissecting cellulitis (boggy nodules/sinus tracts; follicular occlusion tetrad), and acne keloidalis nuchae (posterior scalp/neck plaques; consider laser/excision). 00:00 Alopecia Boot Camp 00:52 Why Hair Loss Is Hard 01:24 Scarring Versus Nonscarring 03:28 Follicular Ostia Clues 05:38 Androgenetic Alopecia Basics 08:05 Treating Pattern Hair Loss 08:34 Minoxidil ICU Story 12:08 Counseling and Transplants 13:44 Alopecia Areata Recognition 17:04 Areata Workup and Treatment 18:30 Telogen Effluvium Shift 20:31 Postpartum Shedding Explained 20:54 Hair Pull Test Basics 21:50 When to Order Labs 23:37 Traction Alopecia Red Flags 26:21 Trichotillomania Patterns 27:42 LPP and FFA Scarring Clues 30:09 Treating LPP and FFA Early 31:33 CCCA Diagnosis and Biopsy 36:04 Rapid Fire Scarring Alopecias 40:19 Clinic Safety Takeaways 41:12 Boot Camp Wrap Up This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.

Send us Fan Mail Hidradenitis Suppurativa (HS) Boot Camp: Diagnosis, Hurley Staging, Treatment Ladder & Surgical Options | The Derm Resident Contact: [email protected] Dr. Jonny Hatch and Dr. Deven Curtis deliver a clinic-focused boot camp on hidradenitis suppurativa (HS), noting the misnomer (not a sweat-gland disease) and reviewing typical intertriginous involvement with painful nodules/abscesses and the pathognomonic double-ended open comedone. They discuss delayed diagnosis, stigma, family history, modifiable factors (smoking and obesity), and flare triggers (menses, friction, sweating, heat, diet). Hurley staging is outlined (I boils only; II recurrent abscesses with sinus tracts/scars; III diffuse interconnected tracts) with emphasis that severity and inflammation may not perfectly match stage. They highlight disease burden (pain, depression screening; associations with Crohn disease, PCOS, metabolic syndrome), exam pearls, and a treatment ladder: topicals (clindamycin with BPO), oral antibiotics (doxycycline, clinda/rifampin; rescue options), hormonal therapy, biologics (adalimumab, infliximab, IL-17 agents), and procedures (I&D, punch deroofing, deroofing, wide excision, reconstruction), plus counseling that HS is chronic, not due to hygiene, and requires ongoing support. 00:00 HS Boot Camp Intro 00:30 Name Origins and Misnomer 02:06 Classic Presentation and Diagnosis 05:04 Risk Factors and Flare Triggers 07:09 Hurley Staging Basics 11:12 Disease Burden and Comorbidities 13:13 Topicals and Lifestyle First Line 15:20 Oral Antibiotics and Escalation 16:58 Hormonal Therapy Pearls 20:00 Biologics for Moderate Severe HS 24:20 Surgical Options and Deroofing 29:38 Patient Counseling and Wrap Up This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.

Send us Fan Mail Psoriasis Part 2: Differentials, Psoriatic Arthritis Screening, and the Psoriasis Treatment Ladder | The Derm Resident Contact: [email protected] Hosts Dr. Jonny Hatch and Dr. Deven Curtis continue psoriasis with a focus on chronic plaque differentials, psoriatic arthritis, and a practical treatment ladder. They review mimickers including seborrheic dermatitis and lichen simplex chronicus (including “sebo-psoriasis”), mycosis fungoides prompting biopsy when plaques are treatment-resistant or atrophic, hypertrophic lichen planus on shins, and guttate-pattern differentials such as pityriasis rosea, pityriasis lichenoides chronica, and secondary syphilis. They emphasize screening for psoriatic arthritis (about one-third of patients; HLA-B27 association) using joint/back pain history, nail findings, and dactylitis, with rheumatology referral when appropriate. Treatments covered include topical steroids by site, calcipotriene, tazarotene, roflumilast foam, tapinarof, phototherapy (narrowband UVB preferred over PUVA), and systemic therapies (methotrexate with folate, cyclosporine, apremilast, acitretin) plus biologics (TNF, IL-17, IL-23, ustekinumab) and deucravacitinib, along with biologic prescreening (TB, hepatitis, CBC/CMP, vaccine counseling) and psoriasis comorbidity risks. 00:00 Show Intro and Disclaimer 00:29 Plaque Psoriasis Differentials 02:21 Guttate Mimickers 03:25 Screening for Psoriatic Arthritis 04:53 Topical Treatment Basics 06:32 Nonsteroid Topicals and New Agents 08:13 Phototherapy UVB and PUVA 10:45 Systemics Methotrexate Deep Dive 13:45 Cyclosporine and Oral Options 18:11 Biologics TNF Alpha Inhibitors 22:41 IL-17 Inhibitors Key Pearls 25:47 IL-23 and IL-12/23 Therapies 28:23 Deucravacitinib and Biologic Workup 30:46 Psoriasis as Systemic Disease 31:32 Closing Pearls and Wrap Up This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.

Send us Fan Mail Chronic Pruritus Workup & Treatment Pearls (CPUO, Neuropathic Itch, Nemolizumab, JAKs) | The Derm Resident Contact: [email protected] Dr. Jonny Hatch hosts Dr. Diego Da Silva, a chronic pruritus expert and host of Skin In the Game, to discuss a practical approach to itch. They outline an initial framework based on distribution (localized vs generalized), time course (with shorter duration and older age raising concern for malignancy), and morphology (primary lesions vs excoriations only). For localized itch without rash, they emphasize neuropathic etiologies (notalgia paresthetica, brachioradial pruritus, meralgia, dysesthesias), consider spine wear-and-tear, and discuss PT plus gabapentinoids and other neuromodulators. For generalized pruritus without rash, they review ROS for constitutional symptoms, recommend considering biopsy of “normal” itchy skin (e.g., CTCL, sarcoid), and suggest labs (CBC, CMP, TSH, A1C, SPEP/IFE, ferritin, vitamin D), chest X-ray, and BP testing/DIF. Treatment pearls include skincare, phototherapy, atopic-directed therapies (dupilumab, nemolizumab), JAK inhibitor counseling (noting shingles risk and “JAKne”), and empiric ivermectin for possible scabies; off-label options include low-dose naltrexone, dronabinol, and intranasal butorphanol, plus advice for residents to develop a niche and “declare” expertise. 00:00 Show Introduction 00:59 Why Itch Matters 01:26 Finding a Niche 04:44 First Steps in Pruritus 07:00 Localized Itch Workup 09:02 Neuropathic Itch Treatments 11:32 Generalized Itch Workup 14:32 Labs Imaging and Biopsy 17:54 Treating CPUO Like Atopy 21:49 Choosing First Biologic 22:27 Nemolizumab Itch Breakthrough 23:58 JAK Inhibitors Safety Reality 26:08 Managing Shingles And Jackne 28:05 Treating Jackne Options 28:54 Derms As Real Doctors 30:54 Low Dose Naltrexone Role 32:15 Scabies And Empiric Ivermectin 33:09 Off Label Itch Rescue Meds 35:42 Advice And Podcast Wrap Up This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.

Send us Fan Mail Atopic Dermatitis Cases & Board Pearls: Eczema Herpeticum/Kaposi’s Varicelliform Eruption, Infection Management, and the Atopic March | The Derm Resident Host dermatology resident Jonny Hatch and Dr. Peter Leo finish an atopic dermatitis episode with cases and board-focused pearls. They review recognition and urgent management of eczema herpeticum (crusted, punched-out lesions), emphasizing HSV PCR/culture, considering bacterial coinfection, empiric antivirals (valacyclovir/acyclovir) and when IV acyclovir/hospitalization is warranted, plus Tzanck smear and biopsy findings (three Ms). They discuss Kaposi’s varicelliform eruption etiologies including eczema coxsackium (supportive care, possible empiric antiviral while ruling out HSV, and onychomadesis) and a life-threatening eczema vaccinatum story. They cover the atopic march, transcutaneous sensitization, LEAP study implications, and why most eczema doesn’t improve with dietary restriction. Practical guidance includes treating impetiginized AD with drying compresses and topical mupirocin, limited oral antibiotics, updated views on bleach baths, bathing frequency, topical steroid potency by vehicle, dupilumab-associated conjunctivitis theories, IL-31-mediated itch, TSLP signaling, site-specific steroid absorption, and why JAK1 selectivity matters. 00:00 Podcast Intro 00:19 Eczema Herpeticum Case 02:04 Testing and Swabs 03:09 Empiric Treatment Plan 04:05 When to Hospitalize 05:27 Tzanck Smear Basics 06:53 Eczema Coxsackium Overview 07:33 Kaposi Varicelliform Story 10:21 Differentiating Coxsackium 11:32 Atopic March Explained 13:56 Diet and Food Allergy Myths 18:13 Bacterial Superinfection Case 20:11 Topicals and Tea Compresses 21:13 Bleach Baths Reality Check 22:01 Topicals Over Orals 23:50 Bleach Baths and Bathing 27:23 Eczema Herpeticum Drill 28:20 Steroid Potency Vehicles 29:11 Dupilumab Eye Effects 31:22 Itch Pathways Explained 32:22 Eczema Coxsackium Care 34:58 Atopic March TSLP 36:42 Steroid Absorption Sites 37:30 Genital Itch Strategy 39:49 JAK STAT6 and Future 41:41 Wrap Up and Thanks This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.

Send us Fan Mail Acne & Rosacea Pearls with Dr. John Barbieri: Diagnosis, Antibiotics, Isotretinoin Dosing, and Pregnancy-Safe Options | The Derm Resident In this “Meet the Expert” episode of The Derm Resident, Dr. Jonny Hatch talks with acne and rosacea expert Dr. John Barbieri about practical, early-resident approaches to acne and common mimickers, emphasizing comedones as a key differentiator and reviewing clues for periorificial dermatitis, rosacea, and pityrosporum folliculitis. They discuss why “jawline acne” is not a strong predictor of PCOS/PMOS and why signs like irregular menses, hirsutism, and acanthosis nigricans are more informative. Dr. Barbieri outlines systemic treatment decision-making, favoring spironolactone over long-term antibiotics in many patients, and reviews antibiotic choices and resistance concerns. The conversation then covers isotretinoin timing, dosing to clinical endpoints, adjuncts to reduce flaring and side effects (loratadine, omega-3, L-carnitine), counseling on growth and mood risk, pregnancy-safe acne options, benzoyl peroxide/benzene concerns, rosacea redness treatment (oxymetazoline), and common trainee mistakes. 00:00 Welcome and Guest Intro 00:42 Acne Exam Basics 01:08 Acne Mimickers 02:36 History and PCOS Clues 03:30 Jawline and Hormones 05:26 Systemic Treatment Choices 07:01 Low Dose Doxy Debate 08:59 Antibiotics as Bridge 10:59 Which Antibiotic to Pick 13:35 Starting Isotretinoin (Accutane) 15:46 Dosing and Endpoints 17:32 Cumulative Dose Myths 19:17 Higher Daily Dosing 20:12 Antihistamine Add On 21:09 Omega 3 For Dryness 22:25 L Carnitine For Soreness 23:42 Growth Stunting Myth 24:33 Mood And Suicide Risk 27:02 Acne In Pregnancy 28:09 Topical Combo Strategies 29:23 Benzoyl Peroxide and Benzene 30:41 Resident Mistakes And Rosacea 33:18 Rosacea Phenotype Approach 34:52 Advice For New Residents 35:30 Final Thanks And Wrap This episode is sponsored by Mind the Skin, a patent-pending, steroid-free, patch system.
