These terms were replaced in 1997 with the release of the revised ILAR (International League of Associations for Rheumatology) classification criteria.There is currently an international movement underway to further revise the classification criteria for JIA, although this is in a preliminary phase.MeSH uses "juvenile arthritis" as the primary entry, and uses "idiopathic", "chronic" and "rheumatoid" in alternate entries.

Similar to the muscular manifestations above, in the mouth, poor tongue control may be observed. Skin
Skin signs and symptoms in Noonan syndrome include lymphedema (lymph swelling of the extremities), keloid formation, excessive scar formation, hyperkeratosis (overdevelopment of outer skin layer), pigmented nevi (darkly pigmented skin spots), and connective tissue disease. Musculoskeletal
Abnormalities in the limbs and extremities may occur in Noonan syndrome. This may manifest as bluntly ended fingers, extra padding on fingers and toes, edema of the back of hands and tops of feet, and cubitus valgus (wide carrying angle of the elbows). For short stature, growth hormone is sometimes combined with IGF-1 (or as an alternative, IGF-1 as a stand-alone) can be used to achieve an increased height/final height quicker. The final adult height of individuals with Noonan syndrome is about 161–167 cm in males and 150–155 cm in females, which approaches the lower limit of normal.Spinal abnormalities may be present up to 30% of the time and this may require surgery to correct in over 60% of these cases. Other musculoskeletal manifestations in Noonan syndrome are associated with undifferentiated connective-tissue disorders which can be associated with joint contractures (tightness) or joint hypermobility (looseness). Additional factors may present in the form of winging of the scapula, scoliosis, breast bone prominence (pectus carinatum), breast bone depression (pectus excavatum). Muscle abnormalities may present as hypotonia (low muscle tone), which may lead to lordosis (increased hollow in the back) due to poor abdominal muscle tone. Heart
Noonan syndrome is the second most common syndromic cause of congenital heart disease.
