Derm: Atopic Eczema: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Atopic Eczema (Dermatitis)🎧 A deep dive into the most common inflammatory skin condition in the UK – understand the pathophysiology, diagnosis, management, and psychosocial impact for MSRA success.🧠 Key Learning Points📌 Definition• Chronic, relapsing inflammatory skin disease• Characterised by intense itch, dryness, and recurrent eczema flares• Commonest in children, but can persist into adulthood📌 Aetiology & Pathophysiology• Multifactorial: genetic predisposition (family history of atopy), skin barrier dysfunction (filaggrin gene defect), immune dysregulation, and environmental triggers• Cycle: Impaired barrier → allergen entry → immune activation → itch → scratch → further barrier damage📌 Risk Factors & Triggers🧬 Risk Factors:Family history (eczema, asthma, hay fever)Urban living, small families, high birth weightPollution, secondhand smoke🔥 Triggers:Irritants (soaps, detergents, perfumes)Skin infections (especially Staph. aureus)Allergens (pollen, dust mites, food)Climate, stress, hormonal shifts, wool clothing📌 Clinical Presentation• Itch is essential• Lesions: dryness, erythema, scaling, papules, vesicles, crusting• Infants: face/scalp/extensors (nappy area spared)• Children/adults: flexures (elbows, knees, neck), hands• Chronic: lichenification, excoriations📌 Differential Diagnoses• Allergic/irritant contact dermatitis• Psoriasis (extensors, silvery scale)• Seborrhoeic dermatitis (greasy, scalp/face)• Tinea corporis (ringworm), scabies, lichen simplex chronicus📌 Complications• Bacterial infection (impetigo, cellulitis)• Eczema herpeticum (HSV superinfection; punched-out erosions, fever, URGENT referral)• Sleep disturbance, low self-esteem, school/work impairment• Atopic march: progression to asthma/allergic rhinitis📌 Investigations• Usually clinical diagnosis• Skin swabs if infection suspected• Allergy testing – only if clear history• IgE – may be raised, not routine• Avoid unvalidated allergy tests📌 Management (Stepwise)🧴 Step 0: Emollients (liberal, daily)💊 Step 1: Topical corticosteroids (potency tailored to severity and site)💊 Step 2: Topical calcineurin inhibitors (face, maintenance, steroid-sparing)💊 Step 3: Systemic (oral steroids for acute flare, antihistamines, antibiotics/antivirals if needed)💊 Step 4: Specialist: immunosuppressants (cyclosporin, azathioprine, methotrexate), phototherapy, biologics (dupilumab, tralokinumab), JAK inhibitors (baricitinib, upadacitinib, abrocitinib)📌 Prognosis• Often improves with age• ~65% clear by age 7, ~74% by age 16• Persistent if early onset + asthma📌 Prevention• No clear prevention; probiotics may help slightly• Early emollient use: research ongoing📎 More MSRA Resources for Atopic Eczema📝 Revision Notes: https://www.passthemsra.com/topic/atopic-eczema-dermatitis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/atopic-eczema-dermatitis-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/atopic-eczema-dermatitis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/atopic-eczema-dermatitis-rapid-quiz/🧪 Topic Quiz: https://www.passthemsra.com/quizzes/atopic-eczema/🎓 Dermatology Course: https://www.passthemsra.com/courses/dermatology-for-the-msra/🌍 Explore the full Dermatology for the MSRA course and 1,000s of revision resources at:👉 https://www.passthemsra.com#MSRA #AtopicEczema #AtopicDermatitis #Dermatology #EczemaHerpeticum #MSRAQuiz #MSRAFlashcards #MSRAAccordions #MSRARevisionNotes #MSRATextbook #MedicalRevision #PassTheMSRA #FreeMSRA
