Eczema: what is it?
Eczema, or atopic dermatitis in its most common form, is a chronic inflammation of the skin: itching, dryness, red patches that sometimes ooze, with locations that change with age (cheeks and folds in babies, elbow and knee creases in children, hands and face in adults). It comes in flares. There is also contact eczema, triggered by a specific product that has to be identified.
Psoriasis: what is it?
Psoriasis is a chronic inflammatory disease with well-defined red plaques covered with whitish scales, frequently on the elbows, knees, lower back or scalp. It can affect the nails (small pits, lifting) and, sometimes, the joints: joint pain or swelling should be reported.
Triggers and flares
These diseases alternate flares and quiet periods. Depending on the person, stress, cold or dry air, certain irritant products, infections or friction favour a flare. Spotting your own triggers helps limit them. In Marrakech, dry winter air and summer air conditioning are frequent triggers.
Principles of treatment
Treatment rests on a diagnosis made by the dermatologist, daily skin care (hydration, suitable products) and, depending on the form and intensity, prescribed treatments, local or general. Follow-up allows the strategy to be adjusted, flares to be spaced out and a product not to be continued without medical advice, in particular poorly dosed topical corticosteroids.
When to consult, and what not to confuse
Consult if itching persists, patches spread or come back, lesions ooze or seem infected, or sleep and daily life are affected. Several skin conditions look like eczema or psoriasis (fungal infection, contact dermatitis, seborrhoeic dermatitis): a clinical diagnosis is essential before any treatment, and an additional test is sometimes discussed.
Children and babies
Eczema is common in children and babies, with care and protocols adapted to age. This is detailed on the clinic's paediatric dermatology page.
Ultrasound: better assessing psoriasis
The clinic has a high-frequency portable ultrasound (Clarius L20 HD3). In psoriasis, it can help assess skin thickness, nail involvement and, together with a rheumatologist, inflammation of tendons and joints. It complements the clinical examination to choose the treatment and follow its effect, depending on the indication.
