  1. Dermatological Conditions Skin Disorders

  2. Terminology • Bulla • Cellulitis • Erythema • Macule • Papule • Pruritic • Pustule • Vesicle

  3. Trauma to the Skin • Blisters • Hot spots, friction, bulla, improper clothing • Tx – drain if necessary, donut, topical antibiotic • Burns • What is difference in the severity of grades • Who is at risk, interaction of some medications • Calluses • Proper foot care • What is the cause? • Chafing • Brought on by sweating, improper clothing; thighs, axilla, jogger’s nipples

  4. Dermatitis/Eczema • Dermatitis • Brought on by dry skin, excessive bathing, low humidity • Eczema • Skin inflammation • Usual symptoms • Dry, flakey, itchy skin

  5. Contact Dermatitis • Brought on by an allergic reaction • Poison ivy, sumac, soap, clothing • S/S - redness, blistering, itchy • Tx • hot vs. cold? • Topical/oral corticosteroids • Oral meds – antihistamines, diphenhydramine

  6. Atopic Dermatitis • Most common form of eczema • Chronic disease • Genetic disorder of skin sensitivity to many sources • S/S • Papules, vesicles, scaly lesions • Extreme itching can lead to secondary infection • Tx • Corticosteroids for itching • Antibiotics for infection • Aveno* soap, no dyes, natural material for clothing

  7. Chronic Eczema – Acute Stage • Large papules (possibly erupting) • Hypo/hyperpigmentation • Typical areas effected • Children – Extensor surfaces • front of knees/back of elbows • Adults – Flexural surfaces • Back of knees/front of elbows • Exacerbations – allergies & stress • Secondary Issues – staph infection

  8. Ways to Prevent & Tx of Dermatitis • Simple Rules • Treat the itch and avoid the irritant • Corticosteroids, Benadryl/Sudafed(careful of sedation) • Treat infection with proper meds • Water/lanolin based lotion • Avoid harsh soaps/perfume/cosmetics • Avoid “hot” showers • Wool clothing, control sweating

  9. Infections Impetigo – staph infection • Bacterial Infections • Enter through a break in the epidermis • Staph • Strep • Pseudomonas

  10. Strep Infections • Erysipelas -Invasion of deeper tissue • Folliculitis – infected hair follicule • Pseudomonas aeruginosa • Form of folliculitis contracted from whirlpools, hot tubs • Red papules

  11. Staph Infections - Boils (furuncle) • Exhibit drainage & pus • Highly infectious • Difficult to distinguish from strep unless culture taken • Transmitted skin-to-skin • Tx topical or oral antibiotics

  12. Boils - treatment • Invasion of deeper tissue • Carbuncle – multiple furuncles • Transmitted with towels/clothing • Tx • Moist compress • Donut • Ickthamol ointment • Pull out to release core, NEVER squeeze

  13. Acne Mechanica • Common adolescent illness • Occurs when sebaceous glands become clogged • No cure, but can be controlled with meds • topical or systemic meds available

  14. Fungal Infections • Common in athletics: • warm, dark, moist environments • worsened with restrictive clothing/equipment (chafing) • Classes=tinea & yeast • Symptoms: • small patches of red, scaly, inflamed areas • smooth (not elevated) • severe itching

  15. Spreads easily Difficult to treat because of re-infection Symptoms improve with change in environment Often treatment >1 month Tx 2wks after sy’s resolve Symptoms: extreme itching red, scaling, inflamed lesions (fissures) yellowish drainage possible Tinea Infections (fungal)

  16. Tinea Pedis (Athlete’s foot) • Most frequent tinea infection • May accompany yeast infections • 1%-3% of people are carriers • Rare in prepubertal children

  17. Tinea Cruris • Jock itch • often originates at feet • may affect men or women • aggravated by tight clothes • spreads easily • linens, towels, etc must be changed daily

  18. Tinea Corporis Gladiatorum • Tinea of the body • “Ringworm” • Affects humans & animals • Circular pruritic patches--well defined with raised borders • Common in wrestling

  19. Yeast infection “sun spots” Most apparent after sun exposure (does not tan) Common in trunk, upper arms/legs, neck not contagious Resembles freckles May be asymptomatic or mildly pruritic Tx: selenium sulfide shampoo or oral antibiotics Yeast Infections - Tinea Versicolor

  20. Parasites - Scabies • Extremely contagious (mite) • Similar to eczema – but no history of disease • Kwell soap/shampoo • Wash towels/sheets daily

  21. Head Lice • Very common in children • Contagious • Don’t confuse with dandruff

  22. Viral Infections – Herpes Simplex • Cold sore, fever blister • Common around lips/face • Many OTC meds • Contagious • Lives in nerves, never goes away

  23. Verruca vulgaris - Warts • Found on Face, hands, feet (plantar warts) • Many methods to destroy • Often return
