Study Notes
Fungal Infections
- Fungal infections are caused by a breakdown in the skin or nails.
- Common types include tinea capitis (scalp), tinea cruris (groin), tinea corporis (body), tinea pedis (feet), and tinea unguium (nails).
- Environmental factors, like humidity and sweating, can worsen these infections.
- Conditions like diabetes, poor hygiene, and poor circulation increase susceptibility.
- Athlete's foot is a common form of tinea pedis.
- Tinea unguium (onychomycosis) requires systemic treatment and typically topical treatment is ineffective.
- Tinea corporis, most common in prepubescent children, can be highly contagious.
- Tinea cruris, or jock itch, is more prevalent in warm, humid environments.
Tinea Capitis
- Commonly affects children.
- Black female children are most affected.
- Infection spreads through direct contact with combs, brushes and common household items.
Fungal Skin Infections
- Location: areas with moisture like feet, groin, scalp, and underarms.
- Signs: May include sogginess, malodorous, and thickened skin; vesicular rash; scaling.
- Symptoms: Itching and pain.
- Distribution: Usually localized to a single region, but can spread.
Contact Dermatitis
- Location: Areas exposed to allergens/irritants.
- Signs: May include raised wheals, fluid filled vesicles or both.
- Symptoms: Itching and pain.
- Distribution: Affects exposed skin areas, it doesn't usually spread.
Bacterial Skin Infection
- Location: Anywhere on the body.
- Signs: Variety of lesions; raised wheals, fluid-filled vesicles, or pustules/ulcers with surrounding redness.
- Symptoms: Itching and pain.
- Distribution: Usually localized, but can spread.
Treatment Goals
- Provide symptomatic relief.
- Eradicate existing infection.
- Prevent future infections.
- For tinea pedis, corporis and cruris, non-prescription antifungal can be effective.
- Tinea unguium and captitis often require referral to a doctor.
Treatment Duration
- Most treatments take 2-6 weeks to work.
- Adherence to treatment is key.
Pharmacologic Therapy
- Topical antifungals like clotrimazole, miconazole, and terbinafine are commonly used (safe for non-RX use).
- Undecylenic acid, and other topical treatments are also applicable.
Additional Considerations
- Warm weather and moist conditions worsen infections.
- Athletes and people who wear tight-fitting clothes often are at high risk.
Warts
- Caused by HPV (human papillomavirus).
- More common in children and young adults.
- Several types of warts: verruca vulgaris (common warts), verruca plana (flat warts), verruca plantaris (plantar warts), periungual warts (around fingernails).
- Symptoms: Warts vary in appearance but are often rough, hard, or flat-topped.
- Treatment options include salicylic acid treatments, cryotherapy, or surgical removal.
Key Points
- Tinea (ringworm) infections are usually mild and treatable.
- Prompt, effective treatment prevents severe complications.
- Treatment adherence is critical for success.
- Self-care exclusions exists for certain conditions (e.g. age, pregnancy, immune conditions).
