Juvenile Arthritis :
Juvenile arthritis is a chronic autoimmune disease where the immune system targets synovium and is commonly seen in children. Synovium is a tissue that lines inside the joint and synovial fluid in the joint. Based on the symptoms and number of joints involved, types of juvenile arthritis are oligoarthritis, polyarthritis, psoriatic arthritis, enthesitis-related arthritis, and systemic arthritis. Symptoms include pain, swelling, tenderness, joint stiffness, fever, rash, weight loss, swollen lymph nodes, fatigue, irritability, eye pain, eye redness, and blurred vision. Diagnosis is made by imaging techniques like X-rays, MRI, blood tests, and urine tests to determine antinuclear antibodies and the degree of inflammation. Treatment can be done using NSAIDs and corticosteroids. If not treated, it can lead to joint damage permanently, interfere with the growth of a child's bones, chronic arthritis, loss of vision, pericarditis, and pleuritis.
