Derm: Nickel Dermatitis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Nickel Dermatitis🎧 A focused deep dive into this common cause of contact dermatitis – understand triggers, diagnosis, and best management for exams and real practice.🧠 Key Learning Points📌 Definition• Allergic contact dermatitis caused by a delayed (Type IV) hypersensitivity reaction to nickel exposure.📌 Causes & Risk Factors• Contact with nickel-containing items: jewellery, watches, belt buckles, coins, zippers, keys• Risk increased by genetic predisposition, history of atopic dermatitis, and repeated exposure• More common in women (linked to jewellery use)💡 Mnemonic: "Nickel Nails Jeans Zippers" – (Nickel, Nail polish, Jeans studs, Zippers)📌 Pathophysiology• Sensitisation phase: nickel binds skin proteins → immune system learns to recognise• On re-exposure: T-cells trigger delayed inflammation (appears 24–48h after contact)📌 Symptoms• Itchy, red, eczematous rash at contact sites• May develop vesicles (blisters), papules, scaling, or lichenification with chronicity• Most common on: earlobes, neck, wrists, abdomen📌 Differential Diagnosis• Other allergic contact dermatitis (e.g., fragrances, latex)• Irritant contact dermatitis (non-immune)• Atopic eczema, fungal infections, drug rashes📌 Diagnosis• Usually clinical (history + exam)• Patch testing is gold standard (confirms allergy)• Consider swabs if secondary infection suspected📌 Management• 🎯 Avoidance is key: nickel-free products, hypoallergenic jewellery, protective coatings• Topical corticosteroids for inflammation/itch• Emollients to support skin barrier• Oral antihistamines for severe itch• Systemic steroids (rare, severe cases only)📌 Complications• Chronic dermatitis and skin thickening• Secondary bacterial infection• Occupational restrictions if persistent exposure📌 Prognosis• Excellent if strict avoidance• Sensitisation is lifelong – reactions on repeat exposure• Education and lifestyle adaptations are crucial📎 More MSRA Resources for Nickel Dermatitis📝 Revision Notes: https://www.passthemsra.com/topic/nickel-dermatitis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/nickel-dermatitis-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/nickel-dermatitis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/nickel-dermatitis-rapid-quiz/🧪 Topic Quiz: https://www.passthemsra.com/quizzes/nickel-dermatitis/🎓 Full Course: https://www.passthemsra.com/courses/dermatology-for-the-msra/🌍 Explore the Dermatology for the MSRA course and 1000s of other resources at:👉 https://www.passthemsra.com#MSRA #NickelDermatitis #AllergicContactDermatitis #DermatologyMSRA #MSRAQuiz #MSRAFlashcards #MSRAAccordions #MSRARevisionNotes #MSRATextbook #ContactDermatitis #Dermatology #OccupationalDermatitis
