Medical Terms Continued (From page 1) —Ulcerative Colitis -A relatively common disease that causes inflammation of the large intestine (the colon). The cause is unknown. Ulcerative colitis is a form of inflammatory bowel disease. It has some similarity to a related disorder, Crohn's disease. The end of the colon (the rectum) is always involved in ulcerative colitis. When the inflammation is limited to the rectum, it is called ulcerative proctitis. The inflammation may extend to varying degrees into the upper parts of the colon. When the entire colon is involved, the terms pancolitis or universal colitis are used.
Common Misspellings: ulcerative collitis, ulcerative colitus
Uveitis —Uveitis: Inflammation of the uvea, the part of the eye that collectively refers to the iris, the choroid of the eye, and the ciliary body. The uvea provides most of the blood supply to the retina. Uveitis as a rule signifies inflammation involving the iris, choroid, and ciliary body -- all three components of the uveal tract. The symptoms of uveitis may be redness of the eye, blurred vision, unusual sensitivity to light, and eye pain.
Deficiency, FALDH —
Deficiency, FALDH : Also known as the Sjogren-Larsson syndrome, this is a genetic (inherited) disease usually characterized by a triad of clinical findings consisting of ichthyosis (thickened fish-like skin), spastic paraplegia (spasticity of the legs) and mental retardation.
The skin changes in the Sjogren-Larsson syndrome are similar to those in congenital ichthyosiform erythroderma, a genetic disease that results in fish-like, reddened skin. Hyperkeratosis (thickening of the skin) is a regular feature. Ecchymoses (bruises) are present at birth or soon after in the Sjogren-Larsson syndrome. Sweating is normal. The spasticity can also affect the arms as well as the legs, resulting in spastic paraplegia. The mental retardation is significant. Most of the patients never walk. About half the patients have seizures.
Eye problems are also part of the syndrome. About half of cases have pigmentary degeneration of the retina. Glistening white dots on the retina are characteristic. People with Sjogren-Larsson syndrome tend to be unusually short. b.i.d. (prescription) -b.i.d. (on prescription): Seen on a prescription, b.i.d. means twice (two times) a day. It is an abbreviation for "bis in die" which in Latin means twice a day. The abbreviation b.i.d. is sometimes written without a period either in lower-case letters as "bid" or in capital letters as "BID". However it is written, it is one of a number of hallowed abbreviations of Latin terms that have been traditionally used in prescriptions to specify the frequency with which medicines should be taken. Other examples: · q.d. (qd or QD) is once a day; q.d. stands for "quaque die" (which means, in Latin, once a day). · t.i.d. (or tid or TID) is three times a day ; t.i.d. stands for "ter in die" (in Latin, 3 times a day). · q.i.d. (or qid or QID) is four times a day; q.i.d. stands for "quater in die" (in Latin, 4 times a day). q_h: If a medicine is to be taken every so-many hours, it is written "q_h"; the "q" standing for "quaque" and the "h" indicating the number of hours. So, for example, "2 caps q4h" means "Take 2 capsules every 4 hours."
