Bacterial Skin Infections

  • Topical or systemic treatments, localized mild infections are treated topically
  • Cellulitis requires systemic antibiotics, which are more effective
  • MRSA infections often require incision and drainage (I&D)
  • Always follow CDC guidelines for treatment

Types of Tinea

  • Tinea pedis (feet), tinea corporis (body), tinea cruris (genital area), tinea capitis (scalp), and tinea unguium (nails)
  • Fungal infections of the scalp and nails are often difficult to treat
  • Systemic antifungal medications (azoles) are often needed for prolonged treatment

Acne

  • Mild acne is treated topically (e.g., Differin, benzoyl peroxide)
  • Moderate acne may require topical and oral antibiotics
  • Severe acne may necessitate isotretinoin (Accutane)
  • Oral contraceptives (OCs) can sometimes improve acne, but not in all cases, estrogens in OCs can make acne worse
  • Spironolactone can be effective for females but not males
  • Treatment duration can vary, sometimes months or more

Lice

  • Insecticidal agents are neurotoxic to lice
  • Permethrin is a commonly recommended treatment
