title: Neonatal Kawasaki disease: case report and data from nationwide survey in Japan.
abstract: Kawasaki disease (KD) is a systemic vasculitis that develops during childhood, with a peak incidence from 6 to 23 months of age. KD also affects younger children, including neonates. We herein describe the case of a 22-day-old patient with incomplete KD. Some characteristics of neonatal KD are also presented with a review of nationwide surveys of KD in Japan involving approximately 130,000 patients during a 12-year period. The surveys identified 23 neonatal cases, accounting for 1/5,500 of patients of all ages with KD. We found that the characteristics of neonatal KD are likely to be incompatible with the classic criteria for KD and that the incidence of coronary disorders in neonatal patients was not statistically higher than that in older patients. These findings are very similar to those of previous reports of neonatal KD.
  
  
  CONCLUSIONS
  Neonatal KD is rare and often presents with only a few features of KD. In addition, both neonatal and older patients with KD are at risk of coronary disorders. These characteristics present a challenge to pediatricians in the diagnosis and treatment of febrile neonates.
