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 .
Childhood arthritis (juvenile arthritis or pediatric rheumatic disease) is an umbrella term used to describe any rheumatic disease or chronic arthritis-related condition which affects individuals under the age of 16. There are several subtypes that differentiate themselves via prognosis, complications, and treatments.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
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 ...
Hemochromatosis may cause hand joint arthritis. Acute rheumatic fever can be differentiated by a migratory pattern of joint involvement and evidence of antecedent streptococcal infection. Bacterial arthritis (such as by Streptococcus) is usually asymmetric, while RA usually involves both sides of the body symmetrically.
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.
Due to the fact that the symptoms of peripheral mononeuropathy and neuropathy can be so diverse, means that the diagnosis of neuropathies can often be difficult and therefore require more medical testing to ensure the appropriate diagnosis. [4] Diagnosing neuropathic disorders often includes:
