Stills disease is a rare form of juvenile rheumatoid arthritis (JRA). It is characterized by systemic inflammation of the connective tissue, which can cause a variety of symptoms. Diagnosis of Still’s disease is based on clinical history, physical examination, laboratory tests, and imaging studies.
Clinical History and Physical Examination
The first step in diagnosing Still’s disease is to take a detailed clinical history from the patient and perform a physical examination. The doctor will ask about the patient’s symptoms, medical history, and family history. The physical examination will include a thorough evaluation of the joints, skin, and other organs.
Laboratory Tests
Laboratory tests are used to help diagnose Still’s disease. Blood tests, such as complete blood count (CBC) and erythrocyte sedimentation rate (ESR), may be used to look for evidence of inflammation. Additional tests, such as rheumatoid factor (RF) and antinuclear antibody (ANA) testing, may also be performed to rule out other causes of joint pain.
Imaging Studies
Imaging studies, such as x-rays and magnetic resonance imaging (MRI), may also be used to diagnose Still’s disease. X-rays can help identify any joint damage or deformities that may be present. MRI can help detect inflammation in the joints and other organs.
The diagnosis of Still’s disease is often difficult and may require a combination of clinical history, physical examination, laboratory tests, and imaging studies. It is important to seek medical attention if you or your child are experiencing any symptoms of Still’s disease, such as joint pain, fever, rash, or fatigue. With early diagnosis and treatment, the symptoms of Still’s disease can be managed.
