| labour onset | <obstetrics> The establishment of regular uterine contractions together with beginning dilatation of the cervix. (12 Dec 1998) |
|---|---|
| labour pains | <obstetrics> Rhythmical uterine contractions which under normal conditions increase in intensity, frequency, and duration, culminating in vaginal delivery of the infant. Synonym: parodynia. (05 Mar 2000) |
| labour, premature | Onset of labour before term but after the foetus has become viable, usually sometime during the 29th through 38th week of gestation. (12 Dec 1998) |
| labour presentation | The part of the foetal body that is in advance in the birth canal. (12 Dec 1998) |
| fourth stage of labour | The hour or two after delivery when the tone of the uterus is established and the uterus contracts down again. (12 Dec 1998) |
| abnormalities, drug-induced | Congenital abnormalities caused by medicinal substances or drugs of abuse given to or taken by the mother, or to which she is inadvertently exposed during the manufacture of such substances. The concept excludes abnormalities resulting from exposure to non-medicinal chemicals in the environment. (12 Dec 1998) |
| abnormalities, radiation-induced | Congenital changes in the morphology of organs produced by exposure to ionizing or non-ionizing radiation. (12 Dec 1998) |
| abortion, induced | Intentional removal of a foetus from the uterus by any of a number of techniques. (popline, 1978) (12 Dec 1998) |
| akathisia, drug-induced | Motor restlessness with sensations of quivering and an urge to move about constantly resulting from the use of certain drugs, such as neuroleptic drugs, which affect the extrapyramidal region of the brain. This differs from dyskinesia, drug-induced in that long-term antipsychotic drug exposure is significantly correlated with the increased prevalence of akathisia while there is no such correlation with dyskinesia. The primary observable distinction between tardive akathisia and dyskinesia appears to be in the repetitive, stereotypy of the dyskinesic movements (lip smacking, for example), while akathisia is associated with anxiety, restlessness, and agitation (psychomotor agitation).

| alpha-chymotrypsin-induced glaucoma | Transient secondary glaucoma following the use of alpha-chymotrypsin in cataract extraction. (05 Mar 2000) |
| antibiotic induced enteritis | <pathology> A condition where the normal intestinal bacteria (useful for digestion) are killed by the use of an antibiotic resulting in symptoms. (27 Sep 1997) |
| antibiotic induced gastroenteritis | <pathology> A condition where the normal intestinal bacteria (useful for digestion) are killed by the use of an antibiotic resulting in symptoms. (27 Sep 1997) |
| antibody induced lysis | <haematology> The term is imprecise and should not be used since there is confusion as to which mechanism is involved, i.e. Natural killing or complement lysis. See: complement lysis, natural killer cells. (09 Feb 1998) |
| asthma, exercise-induced | Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. Inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it). (12 Dec 1998) |
| bacteriophage T7 induced DNA polymerase | <enzyme> Complex of two proteins, phage gene 5 protein and E coli thioredoxin Registry number: EC 2.7.7.- Synonym: t7 phage DNA polymerase, sequenase, t7 DNA polymerase, thermo sequenase (26 Jun 1999) |
