Juvenile Idiopathic Arthritis (JIA) is a chronic condition that causes joint inflammation in children. In some cases, the inflammation also affects the protective sheath surrounding the tendons, a condition known as tenosynovitis. Because tenosynovitis can be difficult to distinguish from regular joint swelling during a standard physical exam, specialized imaging tools like ultrasound are highly useful for an accurate diagnosis. This observational study aims to determine how frequently tenosynovitis occurs in children and adolescents diagnosed with two specific subtypes of the disease: polyarticular and oligoarticular JIA. Researchers will evaluate participants up to 16 years of age receiving care at Assiut University Children Hospital. During the study, patients will undergo a standard clinical assessment, which includes a medical history review and a thorough physical examination of their joints and tendons. Routine laboratory blood tests will also be reviewed. To precisely detect any hidden tendon inflammation, doctors will perform a musculoskeletal ultrasound, which is a safe, radiation-free imaging procedure, on major tendon and joint sites. By comparing the clinical exams with the ultrasound findings, researchers hope to improve the early recognition and management of tendon inflammation in pediatric JIA patients.
