ankylosing spondylitis - a type of arthritis that affects the spine.
antibody - a special protein produced by the body's immune system that recognizes and helps fight infectious agents and other foreign substances that invade the body.
arthralgia - pain in the joint.
arthritis - inflammation of the joint.
arthroscopy - the use of an intra-articular camera inserted into the joint through a small incision to show the inside of a joint; the procedure allows the physician to also assess, repair, or reconstruct various tissues both within and around joints. |

bursitis - inflammation of the bursas. |

cartilage - a connective tissue that covers the ends of bones in a joint.
computerized tomography scan (Also called a CT or CAT scan.) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called "slices"), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays. |

|
dermatomyositis - a type of rheumatic disease in which the blood vessels under the skin and muscles are inflamed, causing damage to the muscle tissue. |

electrocardiogram (ECG or EKG) - a test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and detects heart muscle damage.
electromyography (EMG) - electrical test to determine nerve or muscle damage.
erythrocyte sedimentation rate (ESR) - a measurement of how quickly red blood cells fall to the bottom of a test tube. When swelling and inflammation are present, the blood's proteins clump together and become heavier than normal. Thus, when measured, they fall and settle faster at the bottom of the test tube. Generally, the faster the blood cells fall, the more severe the inflammation. |

K |
|
Kawasaki disease (Also called mucocutaneous lymph node syndrome.) - the most common form of vasculitis that primary affects children. The disease produces irritation and inflammation of many tissues of the body, including the hands, feet, whites of the eyes, mouth, lips, and throat. |

rheumatic fever - a systemic disease accompanied by fever and inflammation that varies in severity, duration, and outcomes. It is frequently followed by serious heart or kidney disease.
rheumatoid arthritis - an inflammatory arthritis that occurs in adults which is characterized by painful and stiff joints on both sides of the body.
rheumatoid factor (RF) - detects whether rheumatoid factor is present in the blood (an antibody found in the blood of most, but not all, people who have rheumatoid arthritis, as well as other rheumatic diseases).
rheumatologist - a physician who specializes in the treatment of arthritis and other rheumatic diseases that may affect joints, muscles, bones, skin, and other tissues. |

scleroderma (Also called systemic sclerosis.) - chronic, degenerative disease that affects the joints, skin, and internal organs.
septic (infectious) arthritis - an infection in the joint fluid and tissues.
spondylitis - inflammation of the spine.
spondyloarthropathy - one of a group of rheumatic diseases characterized by inflammation of the spine and sacroiliac joints, a family history of the disease, similar non-arthritic signs, and the absence of rheumatoid factor (FR) in the blood.
synovial fluid - a clear, sticky fluid secreted by the synovial membrane and released into movable joints.
synovial membrane - a tissue that lines and seals the joint.
systemic juvenile rheumatoid arthritis - a form of juvenile rheumatoid arthritis that affects joints and sometimes internal organs. Fever and rash are important components of the illness.
systemic lupus erythematosus (Also called SLE or lupus.) - an autoimmune disorder characterized by periodic episodes of inflammation of joints, tendons, and other connective tissues and organs. |
