The presence of a crop, or large number, of polypi (see POLYPUS). The most important form of polyposis is that known as familial polyposis coli. This is a hereditary disease characterised by the presence of large numbers of polypoid tumours in the large bowel. Every child born to an affected parent stands a ?fty-?fty chance of developing the disease. Its importance is that sooner or later one or more of these tumours undergoes cancerous change. If the affected gut is removed surgically before this occurs, and preferably before the age of 20, the results are excellent.... polyposis
Previously called juvenile rheumatoid arthritis and juvenile chronic arthritis, this is a set of related conditions of unknown cause affecting children. Characteristically, the synovial membrane of a joint or joints becomes in?amed and swollen for at leat six weeks (and often very much longer – even years). About 1 in 10,000 children develop it each year, many of whom have certain HLA genetic markers, thought to be important in determining who gets the illness. In?ammatory CYTOKINES play a big part.
Clinical features There are various types. The oligoarthritic type involves 1–4 joints (usually knee or ankle) which become hot, swollen and painful. One complication is an in?ammation of the eyes – UVEITIS. The condition often ‘burns out’, but may reappear at any time, even years later.
The polyarthritic type is more like RHEUMATOID ARTHRITIS in adults, and the child may have persistent symptoms leading to major joint deformity and crippling.
The systemic type, previously called Still’s disease, presents with a high fever and rash, enlarged liver, spleen and lymph nodes, and arthritis – although the latter may be mild. In some children the illness becomes recurrent; in others it dies down only to return as polyarthritis.
Complications These include uveitis, which can lead to loss of vision; a failure to thrive; osteoporosis (see under BONE, DISORDERS OF); joint deformity; and psychosocial diffculties.
Treatment This includes ANTIPYRETICS and ANALGESICS, including NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS), intra-articular steroid injections, anti-tumour necrosis factor drugs and steroids.
Physiotherapy is vital, and children may need to wear splints or other orthotic devices to alleviate deformity and pain. Orthopaedic operative procedures may be necessary.... juvenile idiopathic arthritis (jia)
A suggestion by two epidemiologists, made in the British Medical Journal in 2003, that many lives could be saved if all persons aged over 55 took a daily combination pill they termed the polypill. Its components would be ASPIRIN, a CHOLESTEROL-lowering agent, FOLIC ACID and two blood-pressure-lowering agents. The suggestion caused a massive correspondence as it implied treating a whole population rather than individuals considered to be at special risk.... polypill
A group of rheumatoid conditions of unknown causation with onset before 16 years. Girls more than boys. Still’s disease being the form presenting with enlargement of spleen and lymph nodes, high temperature with macular rash comes and goes. Children usually ‘grow out of it’ although stiffness may continue. Deformities possible. Tardy bone growth of the mandibles giving the face a birdlike look. May progress to rheumatoid arthritis (girls) or ankylosing spondylitis (boys). So strong is psychosomatic evidence that sociologists believe it to be a sequel to broken families, divorce or bereavement. Few patients appear to come from a balanced environment or happy home.

See juvenile chronic arthritis.... juvenile arthritis
A rare form of arthritis affecting children. Juvenile chronic arthritis occurs more often in girls, and usually develops between 2 and 4 years of age or around puberty. There are 3 main types. Still’s disease (systemic onset juvenile arthritis) starts with fever, rash, enlarged lymph nodes, abdominal pain, and weight loss. These symptoms last for a period of several weeks. Joint pain, swelling, and stiffness may develop after several months. Polyarticular juvenile arthritis causes pain, swelling, and stiffness in many joints. Pauciarticular juvenile arthritis affects 4 joints or fewer.
Possible complications include short stature, anaemia, pleurisy, pericarditis, and enlargement of the liver and spleen. Uveitis may develop, which, if untreated, may damage vision. Rarely, amyloidosis may occur or kidney failure may develop. Diagnosis is based on the symptoms, together with the results of X-rays and blood tests, and is only made if the condition lasts for longer than 3 months.
Treatment may include antirheumatic drugs, corticosteroid drugs, nonsteroidal anti-inflammatory drugs, or aspirin. Splints may be worn to rest inflamed joints and to reduce the risk of deformities. Physiotherapy reduces the risk of muscle wasting and deformities.
The arthritis usually clears up after several years. However, in some children, the condition remains active into adult life.

see juvenile idiopathic arthritis.... juvenile-onset spondylarthropathy
(JIA, Still’s disease) any one of a group of conditions characterized by inflammation of the joints lasting longer than 6 weeks and occurring before the age of 16. The causes are unknown but immunological and infective mechanisms are suspected. JIA can affect either four or fewer joints (pauciarticular JIA) or more than four (polyarticular JIA). There are two recognized types of pauciarticular JIA: type 1, which generally affects girls below the age of four; and type 2 (juvenile-onset spondylarthropathy), which generally affects boys over the age of nine. There are also two types of polyarticular JIA, depending on the presence or absence of a particular antibody in the blood. There is a great range of severity of these diseases. Treatment consists of pain management and prevention of subsequent deformity or limitation of movement (e.g. contractures). Long-term joint damage is prevented by use of medications similar to those used in rheumatoid arthritis.... juvenile idiopathic arthritis

n. the endoscopic or surgical removal of a *polyp. The technique used depends upon the site and size of the polyp. Endoscopically, polyps can be removed by various methods. A hot biopsy involves coagulation of a small polyp using a diathermy current passed through biopsy forceps, which obtains a sample for analysis at the same time. Cold biopsy involves removal of a polyp using forceps alone, thereby decreasing the perforation risk. Snare polypectomy uses a wire loop (snare) to cut through the base of the polyp. This is performed with or without a diathermy current (hot snare vs. cold snare); the current reduces the risk of bleeding by coagulating local blood vessels as the snare cuts through the polyp. Endoscopic mucosal resection (EMR) involves lifting a flat polyp by injecting a hypertonic solution into the submucosa beneath the polyp followed by snare polypectomy with diathermy. Nasal polyps may be removed using *endoscopic sinus surgery techniques, sometimes utilizing a *microdebrider.... polypectomy
