Still's disease is also known as juvenile-onset rheumatoid arthritis, and is a type of autoimmune disorder in which the body's immune system attacks its own tissues and organs, causing inflammation and pain. This condition is most common in children and young adults between the ages of 5 and 15. This condition can affect any joint in the body, but is most commonly seen in the knees, elbows, wrists, and ankles. Symptoms of Still's disease can include high fever, rash, joint pain and swelling, fatigue, and aching muscles. It can also cause enlargement of the lymph nodes, liver, and spleen.
Still's disease is believed to be an autoimmune disorder, which means that the body's own immune system mistakenly attacks its own tissues and organs. It is not known exactly what causes this condition, but it is believed to be triggered by a combination of environmental, genetic and infectious factors. It is also believed to be linked to other autoimmune disorders, such as lupus and rheumatoid arthritis.
While there is no known cure for Still's disease, treatment focuses on controlling the symptoms and reducing pain and inflammation. Treatment typically includes medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. Physical therapy and exercise can also help to reduce pain and stiffness. In severe cases, surgery may be necessary to repair damaged joints.
