Tinea Capitus Symptoms
Patches of redness and scaling with pustules or papules at edges that may spread to the hairline or neck. Can cause temporary hair loss.
Tinea Capitus Tx
Encourage appropriate hygienic, individual combs, brushes/towels. Antifungal creams/shampoos (Nizoral, Lotrim)

Immune mediated, genetic link.
Linked with asthma or allergic rhinitis.
Eczema Symptoms
Xerosis: dry skin that cracks easily
Acute: Vesicles, exudates, crusts
Subacute: scaling with erythema & excoriation
Chronic: Darkened, thickened skin
Eczema Management
Hydrate skin, humidifier in winter, Topical abx & corticosteroids, antihistamines, loose clothing, avoid triggers that cause flares. Immunomodulator ointments: Protopic, Elidel
Inflammatory disorder of pilosebaceous hair follicles. Occur most on face, chest, shoulders & back.
