## Atopic Dermatitis (Eczema): Clinical Overview
- Focus on pathophysiology, diagnosis, and management protocols for medical students and clinicians.

## Prevalence: A Global Burden
- Most common chronic inflammatory skin disease.
- 60% of cases develop in the first year of life.
- Part of the 'Atopic March': Eczema -> Food Allergy -> Asthma -> Rhinitis.

## Pathophysiology: The Barrier Defect
- **Filaggrin Mutation:** Leads to defective stratum corneum.
- **TEWL:** Increased transepidermal water loss causes xerosis.
- **Immune Dysregulation:** Th2 pathway dominance (IL-4, IL-13).

## Clinical Presentation by Age
- **Infants:** Face, cheeks, scalp, extensor surfaces.
- **Children:** Flexural folds (neck, wrists, antecubital fossae).
- **Adults:** Hands, eyelids, nipples, and flexural areas; common lichenification.

## Common Triggers & Exacerbating Factors
- **Aeroallergens:** Dust mites, dander, pollen.
- **Irritants:** Wool, harsh soaps.
- **Other:** Stress/anxiety and extreme environmental shifts.

## Daily Management: The Foundation
- **Emollients:** Thick creams/ointments applied twice daily; 'soak and seal' method.
- **Bathing:** Short (5-10 min), warm baths using soap-free cleansers.

## Pharmacological Management Ladder
- **Mild:** Low-potency TCS (Hydrocortisone 1-2.5%).
- **Moderate:** Medium-potency TCS (Triamcinolone), TCIs (Tacrolimus).
- **Severe:** High-potency TCS, phototherapy, systemics (Dupilumab, JAK inhibitors).

## Topical Corticosteroid Potency & Dosing
- **Class I:** Clobetasol propionate 0.05%.
- **Class VII:** Hydrocortisone 1-2.5%.
- **Fingertip Unit (FTU):** 1 FTU (~0.5g) treats an area equal to 2 adult palms.

## Red Flags & Complications
- **Infection (S. aureus):** Honey-colored crusts; requires mupirocin or antibiotics.
- **Eczema Herpeticum:** Emergency disseminated HSV; requires immediate Acyclovir.

## Clinical Takeaways
- Importance of patient/parent education on moisturizer application.
- Addressing steroid phobia to prevent undertreatment.
- Proactive maintenance therapy to prevent relapses.
