Kawasaki differential & investigations
GAS, scarlet fever, rheumatic fever, TSS, SJS, adenovirus
ECHO, raised CRP/ESR, raised LFT, ASOT, FBE (platelets raised at 2 weeks)
Note: common findings arthritis, aseptic meningitis, sterile pyuria
Kawaski management
IVIG 2g/kg
Aspirin 5mg/kg at least 6 weeks or until ECHO normal
Prednisolone 2mg/kg if high risk
(Shock, <1yr, Asian, cardiac or liver dx)

Risk of recurrent febrile convulsion
<1 year Family hx febrile convulsion Repeated previous seizures Focal seizure Brief duration between fever and onset
