Studies show that 40% of children with SJIA have a monocyclic disease history, recovering after varying periods. A small percentage experience a polycyclic course, with over half having a prolonged disease course. Juvenile idiopathic arthritis (JIA) is the most prevalent rheumatic illness in children, affecting 1 to 4 out of every 1000. SJIA ...
Polyarticular arthritis is the first type of arthritis, which affects about 30–40% of children with arthritis and is more common in girls than boys. [1] [12] [13] [14] This subtype begins later in childhood and could be subdivided into two types: Rheumatoid Factor (RF) negative and RF positive depending on the presence of the RF antibody ...
Children with systemic JIA usually present with fever and a classic rash and may become quite ill. Late effects of arthritis can include joint contractures (stiff, bent joints with loss of movement) due to joint damage; limb length discrepancies and muscle wasting. Children with JIA vary in the degree to which they are affected by particular ...
Rheumatic fever primarily affects children between ages 5 and 17 years and occurs approximately 20 days after strep throat. In up to a third of cases, the underlying strep infection may not have caused any symptoms. [citation needed] The rate of development of rheumatic fever in individuals with untreated strep infection is estimated to be 3%.
Sydenham's chorea, also known as rheumatic chorea, is a disorder characterized by rapid, uncoordinated jerking movements primarily affecting the face, hands and feet. [1] Sydenham's chorea is an autoimmune disease that results from childhood infection with Group A beta- haemolytic Streptococcus .
Rheumatoid arthritis is derived from the Greek word ῥεύμα-rheuma (nom.), ῥεύματος-rheumatos (gen.) ("flow, current"). The suffix -oid ("resembling") gives the translation as joint inflammation that resembles rheumatic fever. Rhuma which means watery discharge might refer to the fact that the joints are swollen or that the disease ...
Other rheumatological disorders that can cause the features typical for RS3PE include late onset (seronegative) rheumatoid arthritis, acute sarcoidosis, ankylosing spondylitis and other spondyloarthropathies such as psoriatic arthropathy, mixed connective tissue disease, chondrocalcinosis and arthropathy due to amyloidosis.

Rheumatic fever nodules are typically associated with acute rheumatic fever in children. They are not accompanied by rheumatoid factors or bone erosions, but are associated with concomitant joint diseases. No larger than the size of peas, they are typically found at extensor sites and processus spinosi of the vertebrae.
