    Study Notes

    Common Skin Disorders: A Guide for the Community Pharmacist

    • This presentation provides a guide for community pharmacists on common skin disorders.
    • The objectives are: reviewing common skin disorders, identifying appropriate treatments, and understanding patient counseling.

    Dry Skin (Xerosis)

    • Dry skin is caused by decreased water retention in the stratum corneum, resulting in roughness, scaling, inflammation, and itching.
    • Dry skin is a major concern for pharmacists, especially given the growing aging population.
    • Causes of dry skin include: weather, heat, hot baths/showers, harsh soaps/detergents, and other skin conditions.
    • Symptoms include skin tightness, roughness, itching, flaking, scaling, fine lines/cracks, and ashy or gray skin. Some areas may be red, and there may be deep cracks that bleed.

    Treatment of Dry Skin

    • Nonprescription Dry Skin Products:

      • Various petrolatum-containing products (e.g., Absorbase, AmLactin) contain ingredients like petrolatum, mineral oil, ceresin wax, and wool wax alcohol.
      • Urea-containing products (e.g., Carmol 10, Carmol 20) contain urea in different concentrations.
      • Ceramide-containing products (e.g., CeraVe, Eucerin) contain various ceramides.
      • Miscellaneous emollients (e.g., Cetaphil, Gold Bond) with various ingredients (e.g., glycerin, mineral oil, PEG).
    • Nondrug Measures:

      • Avoiding triggers (e.g., excessive bathing, harsh soaps)
      • Using lukewarm water instead of hot water.
      • Patting skin dry after bathing/showering rather than wiping.
      • Drinking plenty of water.
      • Applying moisturizer generously 3-4 times daily within 3 minutes of bathing/showering.

    Atopic Dermatitis (Eczema)

    • Atopic dermatitis is an inflammatory skin condition characterized by periods of flares and remission.
    • Prevalence is increasing globally and over 30 million people in the US have some form of the condition.
    • 50% of affected individuals are diagnosed in their first year, and 85% present before the age of 5. Many do not seek care.
    • Symptoms include itching (pruritus), redness (erythema), papules or vesicles (small bumps or blisters), and plaques and scaling.

    Treatment of Atopic Dermatitis

    • Corticosteroids are the standard treatment when nonprescription therapy isn't sufficient. This is primarily for managing acute flare-ups.
    • Key points for atopic dermatitis and dry skin self-treatment include:
      • Identifying triggers (irritants, temperature extremes, allergens, etc.)
      • Using mild cleansers and applying moisturizers 3-4 times daily after bathing.

    Contact Dermatitis

    • Contact dermatitis is an inflammation caused by an irritant or antigen.
    • Classification includes irritant and allergic contact dermatitis.
    • Symptoms include inflammation, redness, itching, burning, and the formation of vesicles and pustules at the exposure site.
    • Exclusions for self-treatment include conditions that can not be self-managed safely, and symptoms exceeding 1 week, those that are widespread that involve the face, scalp, and neck.

    Treatment of Contact Dermatitis

    • Treating with topical hydrocortisone cream, cool water compresses, lukewarm showers, and colloidal oatmeal baths.
    • For suspected allergic contact dermatitis, additional measures or medical referrals may be required.

    Urushiol-Induced Allergic Contact Dermatitis

    • This presentation covers allergic contact dermatitis caused by urushiol, the oily resin in poison ivy, oak, and sumac plants.
    • Symptoms include noticeable rash and itching at the point of contact; the rash may appear from a few hours to several days after contact.
    • The presentation discusses removing allergens, treating rash symptoms, and preventing future exposure.
    • Treatment often involves removing allergens, treating symptoms, and preventing future exposure using topical and Nondrug treatment and patient counseling.

    Treatment Goals—Removal of Urushiol, Prevention, and Protecting Others.

    • Removing the allergen (urushiol) from the skin.
    • Treating the inflammation.
    • Alleviating itching and limiting scratching.
    • Removing debris from oozing, crusting, scaling vesicles.
    • Preventing secondary skin infections.

    Scaly Dermatoses (Dandruff)

    • Dandruff is a chronic, non-inflammatory scalp condition marked by excessive scaling.
    • Itching, and white flakes on the scalp.
    • Treatment options include cytostatic agents (e.g., pyrithione zinc, coal tar), keratolytic agents (e.g., salicylic acid), and antifungals (e.g., ketoconazole).

    Fungal Skin Infections (Tinea)

    • Includes Tinea pedis ("athlete's foot"), tinea cruris ("jock itch"), tinea corporis (ringworm of the skin), tinea capitis (ringworm of the scalp), and tinea unguium (onychomycosis).
    • Presents with characteristic symptoms like redness and itching.
    • Treatments frequently involve antifungal medications.

    Acne Vulgaris (Acne)

    • An inflammatory skin disorder affecting the pilosebaceous glands, commonly appearing during puberty.
    • Classified as mild, moderate, or severe based on lesion type and scarring potential.
    • Treatment often includes appropriate skin care in addition to first-line therapy including using benzoyl peroxide, topical retinoids, and topical/oral antibiotics (mild, moderate acne) and for severe, or nodulocystic acne, oral isotretinoin is a recommended choice for management.

    Pediculosis Capitis (Head Lice)

    • Caused by the parasitic Pediculus humanus capitis.
    • Characterized by itching on the scalp, and presence of nits (eggs) on hair shafts.
    • Treatment usually involves pyrethroids (e.g., permethrin). Topical application, and good hygiene.

    Warts (Verruca)

    • Result from localised infection of human papillomavirus (HPV).
    • Classification includes common warts (fingers, hands, knees) and plantar warts (soles of the feet).
    • Treatment options typically involve applying caustics (like salicylic acid), freezing (cryotherapy), and/or surgical removal.
    • Self-treatment with OTC agents is often discouraged for diabetic patients due to compromised sensation.
