Juvenile idiopathic arthritis (JIA) is the most common, chronic rheumatic disease of childhood, affecting approximately one per 1,000 children. Juvenile, in this context, refers to disease onset before 16 years of age, while idiopathic refers to a condition with no defined cause, and arthritis is inflammation within the joint.JIA is an autoimmune, noninfective, inflammatory joint disease, the cause of which remains poorly understood. It is characterised by chronic joint inflammation. JIA is a subset of childhood arthritis, but unlike other, more transient forms of childhood arthritis, JIA persists for at least six weeks, and in some children is a lifelong condition. It differs significantly from forms of arthritis commonly seen in adults (osteoarthritis, rheumatoid arthritis), in terms of cause, disease associations, and prognosis. The prognosis for children with JIA has improved dramatically over recent decades, particularly with the introduction of biological therapies and a shift towards more aggressive treatment strategies. JIA treatment aims for normal physical and psychosocial functioning, which is an achievable goal for some children with this condition. Signs and symptoms
Arthritis means inflammation within the joint, and is usually recognised by swelling, pain, stiffness and restricted joint movement. Symptoms of JIA vary from individual to individual. This is mainly because JIA is an umbrella term for several subtypes of JIA, which differ according to the number of affected joints, severity of disease and presence or absence of inflammation in other parts of the body.The key clinical feature in JIA is persistent swelling of the affected joints.
A fundic gland polyp is a type of polyp, found in the fundus of the stomach. Fundic gland polyps are found in 0.8 to 1.9% of patients who undergo esophagogastroduodenoscopy, and are more common in middle-aged women.The risk of malignancy is very low or none, when sporadic.Fundic gland polyposis is a medical syndrome with multiple fundic gland polyps. The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically. == References ==
