Background
- Superficial epidermal infection characterized by amber crusts (nonbullous) or vesicles (bullous)
- May be super-infection or primary infection
- Typical causative organisms are Staphylococcus. aureus or Streptococcus pyogenes
- Fever and systemic signs are uncommon
- Postinfectious Glomerulonephritis is a possible complication
Diagnosis
- Nonbullous
- Erythematous macules/papules develop into vesicles which become pustular and rupture
- As rupture release yellow fluid which dries to form stratified golden crust
- Erythematous macules/papules develop into vesicles which become pustular and rupture
- Bullous
- Bullae form as result of staph toxin
- Some cases caused by MRSA
Treatment
- Topical antibiotics
- Mupirocin ointment 2% TID x 7-14d
- Oral antibiotics
- Consider for large areas or if topical treatment is impractical or for bullous impetigo
- Clindamycin 24mg/kg/d in 3 doses x7-10d
