| pregnancy trimesters | The three periods of three months each in the normal pregnancy. (12 Dec 1998) |
|---|---|
| pregnancy tumour | A pyogenic granuloma developing on the gingiva during pregnancy; thought to be related to hormonally altered response of the oral mucous membranes to local irritants such as bacterial plaque on adjacent teeth. Synonym: pregnancy tumour. (05 Mar 2000) |
| pregnancy zone proteins | Glycoproteins with the electrophoretic mobility of an alpha 2-globulin. They are found in small amounts in normal human plasma but in much larger volume in the plasma of pregnant women. These proteins have also been found in increased amounts in individuals undergoing oestrogen therapy and are sometimes produced ectopically by tumours of non-placental origin. Pregnancy zone proteins are believed to be of maternal rather than placental origin. (12 Dec 1998) |
| pregnancy, abdominal | Ectopic pregnancy with development of the foetus in the abdominal cavity. (12 Dec 1998) |
| pregnancy, alcohol in | The consumption of alcohol during pregnancy carries the danger of damaging the foetus and causing foetal alcohol syndrome or foetal alcohol effects. (12 Dec 1998) |
| pregnancy, ectopic | A pregnancy that is not in the usual place and is located outside the inner lining of the uterus. A fertilised egg settles and grows in any location other than the inner lining of the uterus. The vast majority of ectopic pregnancies occur in the fallopian tube (95%), however, they can occur in other locations, such as the ovary, cervix, and abdominal cavity. An ectopic pregnancy occurs in about 1 in 60 pregnancies. A major concern with an ectopic pregnancy is internal bleeding. If there is any doubt, seek medical attention promptly. (12 Dec 1998) |
| pregnancy, ectopic, symptoms of | Symptoms of an ectopic pregnancy can often be vague and include vaginal bleeding, abdominal or pelvic pain (usually stronger on one side),shoulder pain, weakness, or dizziness. Weakness, dizziness, and a sense of passing out upon standing can represent serious internal bleeding, requiring immediate medical attention. (12 Dec 1998) |
| pregnancy, high-risk | Pregnancy in which the mother and/or foetus are at greater than normal risk of morbidity or mortality. Causes include lack of adequate prenatal care, previous obstetrical history, pre-existing maternal disease or pregnancy-induced disease, and multiple gestation, as well as advanced maternal age. (12 Dec 1998) |
| pregnancy, multiple | The condition of bearing two or more foetuses simultaneously. (12 Dec 1998) |
| pregnancy, prolonged | Pregnancy continuing beyond the normal duration; in humans, usually beyond 294 days after the beginning of the last menses. (12 Dec 1998) |
| pregnancy, tubal | Ectopic pregnancy within an oviduct. (12 Dec 1998) |
| pregnancy, unwanted | Pregnancy, usually accidental or unplanned, that is not desired by the parent or parents. (12 Dec 1998) |
| pregnancy-associated alpha-plasma protein | An alpha 2-macroglobulin, molecular weight approximately 750,000 now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during the second trimester and continue to rise until the end of gestation. (12 Dec 1998) |
| pregnancy-associated beta-plasma protein | A beta-globulin now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during pregnancy until the end of gestation. (12 Dec 1998) |
| pregnancy-associated esterase | <enzyme> In baboons, amount of activity correlates with stage of pregnancy; hydrolyzes alpha-naphthyl butyrate in preference to alpha-naphthyl acetate Registry number: EC 3.1.1.- Synonym: pregnancy esterase (26 Jun 1999) |
