Colitis, ulcerative: A bowel disease that is characterized by inflammation with ulcer formation in the lining of colon (large intestine). Its cause is unknown. The end of the colon (the rectum) is generally involved. When limited to the rectum, the disease is called ulcerative proctitis. The inflammation may extend to varying degrees into the upper parts of the colon. When the entire colon is involved, it is referred to as pancolitis or universal colitis. Symptoms include intermittent rectal bleeding, crampy abdominal pain, and diarrhea. Many patients experience long remissions, even without medication. Ulcerative colitis may mysteriously resolve after a long history of symptoms. Direct visualization (via sigmoidoscopy or colonoscopy) and biopsy of the lining of the bowel is the most accurate diagnostic test. Treatment of ulcerative colitis involves medications and/or surgery; changes in diet can sometimes help.

Collagen injection: The practice of injecting collagen into a part of the face or body (often the lips) to make it larger. The effects are long-lasting but not permanent. Collagen injections are usually done by plastic surgeons.
Collagenopathy: Any one of a congenital and rare group of disorders that affect connective tissue. Connective tissue supports the body’s joints and organs. The collagenopathies are caused by defects in type II or type XI collagen. Collagens are complex molecules that provide structure, strength, and elasticity (the ability to stretch) to connective tissue. The conditions […]
