Staphylococcal scalded skin syndrome: Case

This neonate presents generalised staphylococcal scalded skin syndrome, or Ritter disease, with the characteristic prodrome of irritability and poor feeding, scarlet erythema around the mouth and in the nappy area, and sheet-like peeling with a positive Nikolsky sign. The sticky eye over the preceding three days is the likely staphylococcal focus generating the toxin, which is the typical pattern in a neonate. The intact oral and conjunctival mucosae confirm the diagnosis against Stevens-Johnson syndrome, in which the mucosae would be ulcerated. [2]

Clinical findings

The key findings are the extensive superficial skin loss, the tenderness, and the tachycardia with a prolonged capillary refill that signal fluid loss and evolving dehydration. The candidate should estimate the extent of skin involvement as a percentage of body surface area, because the fluid and heat losses scale with that figure in a small neonate. The intact mucosae should be documented explicitly, because their involvement would shift the diagnosis toward a drug-induced reaction rather than SSSS. [3]

The sticky eye is the portal of entry, and the candidate should examine the conjunctiva, the umbilicus, the nasopharynx, and the nappy area for the staphylococcal focus. Blood cultures should be drawn but are usually negative, because only the toxin circulates and the organism stays at its local focus. A swab of the sticky eye is more likely to grow the toxigenic Staphylococcus aureus and confirm the source. A skin biopsy is rarely required in a typical case, because the clinical picture is characteristic. [2]

Management

The neonate needs admission to a neonatal unit for intravenous anti-staphylococcal therapy, fluid and temperature monitoring, and skin care. Intravenous flucloxacillin or cefazolin is first-line, with clindamycin added to suppress toxin synthesis in this extensive disease. Vancomycin replaces flucloxacillin if methicillin-resistant Staphylococcus aureus is suspected or prevalent locally. The antibiotic should be given immediately after cultures and swabs are drawn, because halting toxin production is the definitive act of therapy. [3]

Supportive care is as important as the antibiotic. Analgesia should precede any handling of the raw skin, intravenous fluids should cover maintenance plus the insensible loss across the denuded surface, and a neutral thermal environment prevents hypothermia. Emollients and non-adherent dressings protect the healing skin, and the family should be counselled that healing occurs without scarring within one to two weeks. The small body surface area of a neonate makes fluid and heat losses proportionally greater, which is the reason for the low threshold for neonatal admission. [2]

Complications and follow-up

A single case of neonatal SSSS on a postnatal ward should trigger a search for a carrier among staff and parents, because nosocomial nursery outbreaks trace to asymptomatic carriers of the toxigenic strain. Investigation includes nasal and fingertip swabs of staff and parents, cohorting of affected and exposed infants, and reinforcement of hand hygiene. Once a carrier is identified, eradication therapy interrupts transmission and prevents further cases. [1]

The neonate should be observed for dehydration, hypothermia, and secondary infection until the skin re-epithelialises. Follow-up confirms complete healing without scarring, identifies any persistent focus that could drive recurrence, and addresses the carrier status that led to the outbreak. The family should leave with written advice about the expected course, the signs of deterioration, and the reassuring fact that complete healing is the norm in a treated neonate. [3]
