II. Definitions
- Tinea
- Dermatophytes
- Fungal organisms that cause Tinea
- Dermatophytes inhabit keratinized tissues (hair, skin and nails)
- Dermatophytes are able to digest keratin via keratinase secretion
- Includes three genera: Trichophyton, Microsporum, Epidermophyton
- Overall, >30 dermatophyte species that infect humans
III. Conditions: Tinea
- Children
- Tinea Capitis (scalp infection)
- Tinea Corporis (Ringworm)
- Tinea Faciale (facial infection)
- Adolescents and adults
- Tinea Manum (Hand Infection)
- Tinea Pedis (Athlete's Foot)
- Tinea Unguium (Onychomycosis, ToenailFungus)
- Pityriasis Versicolor or as previoulsy known, Tinea Versicolor (uneven tanning on the trunk )
- Adolescent and adult males
IV. Conditions: Other Cutaneous Fungal Infections
V. Management: Pearls
- Limit Nystatin use to Cutaneous Candidiasis (not effective against Tinea Infections)
- Butenafine (Lotrimin) and Terbinafine (Lamasil) are preferred topical agents for tinea
- Avoid oral Ketoconazole due to hepatotoxicity
- Avoid combination agents containing Antifungals with high-potency Corticosteroids
- Dilutes the Antifungal concentration and may exacerbate the Fungal Infection
