Staph Scalded-Skin Syndrome
The Chief Complaint of “rash” is such a misleading complaint. It seems so innocuous…“I’ll just run in this room real quick and diagnose non-specific viral rash in a well appearing kid and be done.” But, we all know that there are a few specific characteristics of rashes that catch our attention and, perhaps, portend something more concerning occurring somewhere underneath the skin. Let us look at one of these concerning entities: Staph Scalded Skin Syndrome.
A General Approach to Rashes
- Some attention grabbing rash characteristics [I often comment on the lack of these (hopefully) in all of my non-specific rash patients]
– Petechiae, Purpura, Vesicles, Bullae, Peeling / Desquamation, Target Lesions
- Certainly, these don’t always mean there is “badness” lurking… but they do make you think a little harder (ex. Petechiae above the nipple line in a child with significant coughing or vomiting may not warrant any further work-up for the rash).
Staph Scalded Skin Syndrome
- Blistering disorder due to S. aureus infection producing an Exfoliative Toxin
- Most common in first 3 months of life and in children <5yrs, but can occur in adults as well.
- Severity ranges from localized blistering (bullous impetigo) to generalized desquamation (Staph Scalded Skin Syndrome).
- Skin Lesions
- Initially, a fine scarlatiniform rash may be seen
- Over the next 24hrs, an increasing erythema develops, especially around the mouth and nose, face, neck, axillae, and groin. This can be tender.
- This becomes more widespread over 24-48 hours.
- Sloughing occurs initially over face, flexural areas, and pressure points.
- + Nikolsky’s sign
- Flaccid bullae easily rupture leaving red, moist erosions.
- Desquamation will heal without scarring.
- Mucous membranes are NOT involved with SSSS.
Staph Scalded Skin Syndrome Management Considerations
- Mortality is low (as it can be treated effectively with antibiotics), but Morbidity is high.
- Diagnosis is Clinical!!
- Confirmation can be done with skin biopsy (but not in the ED)
- Cultures can be misleading – ~50% of Toxic Epidermal Necrolysis will have + cultures.
- Most often confused with TEN – but management is different (TEN often responds to steroids, which would potentially worsen SSSS).
- SSSS doesn’t involve Mucous Membranes
- TEN often associated with medications or viral illness
- SSSS usually evolves gradually, starting with a localized exfoliating rash.
- If diagnosed early, with only localized involvement, and the child is well-appearing, may begin therapy with oral abx (penicillinase-resistant penicillins) and follow-up within 48hrs (often in the first 24 hrs, toxins will still produce new lesions).
- If rash continues to spread after 48 hours, or at any time the child becomes toxic, than admission for close monitoring of fluid status is recommended.
- If the patient initially presents with a generalized involvement, then admission is recommended.
- Extensive exfoliation may best be managed in a burn center.
- Most do not need broad-spectrum antibiotics; however, there are several reports of MRSA leading to SSSS… so keep that in mind.
