Editor's Notes
- Less than 5 years age –fever followed by upper respiratory tract infection ,pharyngitis & conjunctivitis. Positive nikolesky sign
- Toxins exfolative /epidrmolytic –causing peeling of outer layer of skin & finally blister formation
- CXR to see pneumonia as primary cause of infection Wound culture from nose /conjectiva/axila
- Ten almost always mucous membrane is involved (mouth/conjectiva/trachea/esophagus/anus/vagin antibiotics-most are resistant to penicillin's –so start pencillin resistant synthetic pencillin –nafcillin/oxacallin & if MARSA is suspected vancomycin/linizolid should be given
- Baby recent visit to hospital –initially there was a blister then quickly brusts & leaves a cresty golden patch
- Highly contagious spread by direct contact ,minor abrasions predispose to infection
- Diagnosis is clinical ,blood cultures are needed somtimes
- Self limiting /avoid precipitating factors/
- EM- self limiting hypersensitivity reaction ,EM major>10% TBSA involved ..mcc HSV Types: SJS <10% TEN>30%
