, juvenile rheumatoid arthritis
chronic arthritis beginning in childhood, most cases of which are pauciarticular, that is, affecting few joints. Several patterns of illness have been identified. In one subset, primarily affecting girls, iritis is common and antinuclear antibody is usually present; another subset, primarily affecting boys, frequently includes spinal arthritis resembling ankylosing spondylitis. Some cases are true rheumatoid arthritis beginning in childhood and characterized by the presence of rheumatoid factor and destructive deforming joint changes, often going into remission at puberty.

; JCA; juvenile idiopathic arthritis; JIA; Still's disease group of inflammatory, immune-mediated arthropathies (i.e. systemic arthritis, oligoarthritis, polyarthritis [rheumatoid factor-negative/RF-ve, antinuclear factor-positive/ANF+ve, or RF-ve, ANF-ve, or RF+ve], juvenile psoriatic arthritis [RF-ve], enthesis-related arthritis, other arthritides) affecting children aged <16 years (may present at <4 years of age); girls affected more than boys; indicated by presence of inflammatory arthropathy (of one or more joints for longer than 6 weeks); presents as chronic, idiopathic, monoarthritis (e.g. hip, knee, ankle, subtalar joint); recruitment of other joints occurs in polyarticular form; inflammation may involve ossification centres, leading to limb length discrepancy, hallux abductovalgus, pes cavus, pes planus and altered plantar pressures; condition is managed by drug therapies and ongoing provision of in-shoe orthoses
