Study Notes

Learning Objectives

Review definitions and descriptions of various skin conditions.
Discuss non-prescription products for treatment.
Identify drug mechanisms, interactions, adverse effects, contraindications, and allergies related to dermatological products.

Common Skin Conditions

Acne: Increased sebum production, inflammation, and bacterial colonization; may cause scarring.
Dermatitis: Includes various forms like atopic and contact dermatitis.
Dry Skin (xerosis): Characterized by roughness, flaking, and itchiness; often related to moisture loss.
Insect Bites: May lead to allergic reactions or disease transmission.
Minor Cuts & Wounds: Disruption of skin structure due to trauma, requires specific management.

Pharmacist Prescribing for Minor Ailments

Conditions include allergic rhinitis, conjunctivitis, diaper dermatitis, and musculoskeletal sprains.
Pharmacists recommend topical analgesics, moisturizers, and oral antihistamines for symptomatic relief.

Pharmacists' Most Recommended Products

Includes medications for eczema, dry skin relief, oral arthritis pain, and emergency contraception.
Key recommendations feature benzoyl peroxide, hydrocortisone, and various moisturizing agents.

Role of Pharmacy Technicians

Gather lifestyle and medical background to identify disease triggers.
Ensure stock of moisturizers and facilitate patient education sessions.
Assist in medication usage discussions through open-ended questions.

Acne

Risk Factors: Family history, hormonal changes, and high testosterone levels.
Goals of Therapy: Alleviate symptoms, limit progression, and prevent scarring.
Aggravating Factors: Hormonal fluctuations, oil-based products, and environmental irritants.
Treatments:
- Nonpharmacological: Mild cleansing regime, mechanical exfoliation, and dietary adjustments.
- Pharmacological: Benzoyl peroxide, retinoids, and antibiotics are commonly prescribed.

Dermatitis

Diaper Dermatitis: Acute inflammatory reaction due to prolonged exposure to moisture combined with irritants.
Goals of Therapy: Relieve symptoms and prevent recurrence.
Pharmacological Treatment: Use of zinc oxide, topical antifungals for Candida, and low-potency corticosteroids in severe cases.

Dry Skin

Characterized by water loss and potential for cracks and itchiness.
Goals of Therapy: Restore hydration and maintain skin barrier integrity.
Nonpharmacologic Treatment: Gentle cleansing methods and frequent moisturization.
Pharmacological Treatment: Emollients, humectants, and barrier repair agents are suggested for effective management.

Insect Bites

Treatment focuses on prevention and symptomatic relief of reactions.
Prevention Strategies: Avoid scented products, wear protective clothing, and limit outdoor activity during peak insect hours.
Pharmacologic Treatments: Include DEET for repellency and topical corticosteroids for itch relief.

Minor Cuts and Wounds

Classification: Acute wounds heal quickly while chronic wounds require specialized management.
Goals of Therapy: Optimize healing environment, prevent infection, and minimize discomfort.
Wound Complications: Recognition of infection signs and the importance of keeping wounds clean and moist to reduce scarring.

Wound Management Steps

Cleanse the wound gently and thoroughly.
Apply pressure to control bleeding.
Use appropriate dressings to protect and promote healing.### Cleansing and Antiseptic Agents
Saline is a tissue-friendly cleansing agent.
Isopropyl alcohol 70% is effective as a bactericidal disinfectant, used at 70% to 90%.
Hydrogen peroxide 3% acts as an oxidizing agent with antiseptic and deodorant properties, but can impair wound healing and cause irritation.
Iodine is preferred in water solution for disinfecting contaminated wounds, but is contraindicated in iodine allergy and may stain skin/clothing.
Povidone-iodine is a broad-spectrum disinfectant for contaminated wounds and skin preparation but may cause systemic absorption issues.

Topical Antibacterials

Topical antibiotics (bacitracin, neomycin, polymyxin B) provide broad coverage against gram-positive and gram-negative bacteria.
Resistance to these agents is uncommon but can develop with prolonged use; common side effects include localized itching and burning.
Polysporin combines polymyxin B, bacitracin, and gramicidin; it should not be used on large areas, deep wounds, or serious burns.

Foot Care for People with Diabetes

Regularly inspect feet for injuries.
Bathe and keep feet moisturized to prevent dryness.
Trim nails carefully to avoid ingrown toenails.
Choose appropriate shoes and socks to protect feet.

Sunburn and the Skin

Skin functions include protection against injury, controlling temperature, preventing microbial invasion, and blocking harmful sun radiation.
Sun Protection Factor (SPF) rates sunscreen effectiveness; products range from SPF 4 to SPF 100.

UVA & UVB Sunrays

UVA rays penetrate deeper layers, present all day, and can cause photoaging and skin cancer.
UVB rays primarily damage the outer skin layers, causing sunburn and associated inflammatory responses; they are strongest between 10am and 4pm.

Sun-Induced Skin Damage

Acute effects include sunburn and phototoxic reactions.
Chronic effects lead to photoaging, pigmentary changes, and increased risk of skin cancers.

Goals of Therapy

Aim to prevent sunburn, manage pain, minimize infection risk from burns, and reduce long-term damage like photoaging and skin cancer.

Photoaging

Defined as premature skin aging from UV exposure; prevention methods include avoiding peak UV hours and wearing protective clothing.

Canadian Dermatology Association Recommendations

Sunscreens should have at least SPF 30, broad-spectrum protection, be hypoallergenic, and minimally perfumed.

Pharmacological Treatment

Sunscreen products significantly reduce tanning and sunburn; minimum SPF recommended is 30.
Adverse effects may include skin sensitivity, allergic reactions, and worsening acne.

Sunscreens

Active ingredients differ in UV protection; broad-spectrum sunscreens offer the best defense.
Physical sunscreens reflect UV radiation while chemical sunscreens absorb it.

Drugs That May Cause Photosensitivity

Certain antibiotics, diuretics, statins, psychiatric medications, and NSAIDs can increase sensitivity to sunlight.

Sunburn Treatment

Effective treatments include cool compresses, analgesics like ibuprofen, topical aloe vera, and moisturizing agents.

Sunscreen Product Recalls

Johnson & Johnson recalled specific spray-on sunscreens due to elevated benzene levels, linked to serious health risks.

Melanoma Detection: ABCDE Method

Learn to detect melanoma using the ABCDE method, which includes assessing asymmetry, border, color, diameter, and evolving characteristics of moles.
