Arthritis
Arthritis is a general term for approximately 100 diseases that produce either INFLAMMATION of connective tissues, particularly in joints, or noninflammatory degeneration of these tissues. The word means "joint inflammation," but because other structures are also affected, the diseases are often called connective tissue diseases. The terms rheumatism and rheumatic diseases are also used. Besides conditions so named, the diseases include gout, lupus erythematosus, ankylosing spondylitis, degenerative joint disease, and many others, among them the more recently identified LYME DISEASE. Causes of these disorders include immune-system reactions and the wear and tear of aging, while research indicates that the nervous system may often be equally involved. About one out of seven Americans exhibit some form of arthritis. INFLAMMATORY CONNECTIVE TISSUE DISEASES This varied group of diseases produces inflammation in the connective tissues, particularly in the joints. The signs of inflammation--warmth, redness, swelling, and pain--may be apparent. Microscopic examination of the lesions reveals prominent blood vessels, abnormal accumulations of white blood cells, and varying degrees of wound healing with scarring. In some diseases, the inflammation is clearly an immune reaction, the body's defense against invading microorganisms. In others, the cause is different or unknown. Infectious Arthritis This disease is most common in young adults. Infection in a joint is usually caused by bacteria or other microorganisms that invade the joint from its blood vessels. Within hours or a few days the joint, usually the knee or elbow, becomes inflamed. There is an abnormal accumulation of synovial, or joint, fluid, which may be cloudy and contain large numbers of white blood cells. Gonococcal arthritis, a complication of gonorrhea, is the most common form of infectious arthritis. Treatment with antibiotics and aspiration of synovial fluid is usually promptly effective, and only minor residual damage is done to the joint. Occasionally the infection is prolonged and produces joint destruction and requires surgery. Rheumatic Fever This is a form of infectious arthritis caused by hemolytic streptococcus, a bacterium. Unlike typical infectious arthritis, however, the disease is most common in children aged 5 to 15 years, begins weeks after the onset of the streptococcal infection, and streptococci cannot be isolated from the joint fluid. The inflammatory process may involv...This is not the end of the termpaper! Register below to see the complete version of this term paper.
