ADE
|
|
ADEAdverse drug event. See: Adverse reaction.
RELATED TERMS--------------------------------------
Event
A set of outcomes. Cardiovascular events might include a heart attack and gastrointestinal events a GI bleed. The use of the term "event" in medicine comes from probability theory.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Additive genetic effects
A mechanism of quantitative inheritance such that the combined effects of genetic alleles at two or more gene loci are equal to the sum of their individual effects.
Adducted thumbs with mental retardation
"A syndrome with the following characteristic features:
Adduction
"Movement of a limb toward the midline of the body. The opposite of adduction is abduction. An adductor muscle pulls toward the midline of the body. For example, the adductor muscles of the legs pull the legs toward the midline of the body so the legs are closer together. From the Latin prefix ""ad"" meaning ""toward"" + ""ducere"" meaning ""to draw or lead"" = ""to draw toward."""
Adductor muscle
"Any muscle that pulls a body part toward the midline. For example, the adductor muscles of the legs pull the legs toward the midline of the body so the legs are closer together. The word ""adductor"" comes from the Latin prefix ""ad"" meaning ""toward"" + ""ducere"" meaning ""to draw or lead"" = ""to draw toward."" The opposite of ""adductor"" is ""abductor."" An adductor muscle opposes an abductor muscle."
Adductor spasmodic dysphonia
A disorder in which sudden muscle spasms cause the vocal folds (or vocal cords) to slam together. See: spasmodic dysphonia.
ADE
Aden-
See: Adeno-.
Adenine (A)
"One member of the A-T (adenine-thymine) base pair in DNA. The other base pair in DNA is G-C (guanine-cytosine). Each base pair forms a ""rung of the DNA ladder."" A DNA nucleotide is made of a molecule of sugar, a molecule of phosphoric acid, and a molecule called a base. The bases are the ""letters"" that spell out the genetic code. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). The base pairs in RNA are therefore A-U and G-C."
Adeno-
"Prefix referring to a gland, as in adenoma and adenopathy. From the Greek aden meaning originally ""an acorn"" and later ""a gland"" in the form of an acorn. Before a vowel, adeno- becomes aden-, as in adenitis (inflammation of a gland)."
Adenoid cystic carcinoma
"A type of cancer that most often develops in the salivary glands of the head and neck. It may arise in other sites such as the skin, lacrimal gland, trachea, breast, cervix and prostate. Adenoid cystic carcinoma (ACC) has a characteristic appearance under the microscope. Abnormal ""nests"" or cords of certain cells (epithelial cells) can be seen to surround or infiltrate ducts and glandular structures. These structures are typically filled with a mucous-like material or contain abnormal fibrous membranes (hyaline membranes). ACC is an unusual tumor. It is slow-growing but relentless. It tends to be locally invasive and infiltrate the ""sheaths"" or coatings surrounding nerve fibers (perineural spaces). ACC often recurs years later at the site where the tumor first arose or it may metastasize. Unlike most carcinomas, it seldom metastasizes to nearby lymph nodes but rather to distant sites. The lung is the most common site of metastasis, with the liver second. Bone metastases indicate a poor prognosis . Treatment usually involves surgery to resect (remove) the tumor. Postoperative radiotherapy may help prevent local recurrence. Chemotherapy may slow the tumor but no chemotherapy has yet been found that is effective in destroying it."
Adenoidectomy
The surgical removal of the adenoids.
