AB  - The  term  juvenile  idiopathic  arthritis  (JIA),  formerly  known  as  juvenile  rheumatoid  arthritis,  describes  several  subtypes  of  chronic  childhood  arthritis  further  classified  by  number  of  joints  involved  and  other  clinical  characteristics.  Oligoarticular  JIA  (less  than  five  joints  involved)  and  polyarticular  JIA  (five  or  more  joints  involved)  patients  generally  present  with  joint  swelling  with  painful,  limited  range  of  motion  that  persists  for  more  than  6  weeks.  Joints  may  be  warm  but  are  not  typically  erythematous.  The  onset  is  usually  insidious,  but  these  patients  may  present  to  the  ED  with  concern  for  mechanical  injury  or  infection.  Systemic  JIA  (known  as  Still  disease  in  adults)  is  an  important  distinct  category  of  disease  characterized  by  arthritis  in  addition  to  a  classic  daily  fever  (often  spiking  in  the  evening)  with  accompanying  erythematous  macular  rash  that  tends  to  worsen  with  the  fever.  Patients  with  systemic  JIA  are  at  risk  for  developing  macrophage  activation  syndrome,  especially  early  in  the  disease  course  and  with  infections.
