| menopause, premature | Premature failure of ovulation associated with the permanent disappearance of oocytes and follicles from the ovary in women under the age of 40. If failure occurs while follicles are still present, the condition is called premature ovarian failure (ovarian failure, premature). (12 Dec 1998) |
|---|---|
| premature | 1. Occurring before the proper time. 2. <paediatrics> A premature infant. Origin: L. Praematurus = early ripe (18 Nov 1997) |
| premature beat | A premature contraction of the heart that is independent of the normal rhythm and arises in response to an impulse in some part of the heart other than the sinoatrial node. Synonym: premature beat. (18 Nov 1997) |
| premature contact | A condition of tooth contact's which diverts the mandible from a normal path of closure to centric jaw relation. Synonym: cuspal interference, interceptive occlusal contact, premature contact. (05 Mar 2000) |
| premature delivery | Birth of a foetus before its proper time. See: premature birth. (05 Mar 2000) |
| premature labour | Onset of labour before the 37th completed week of pregnancy dated from the last normal menstrual period. (05 Mar 2000) |
| premature senility syndrome | <syndrome> Accelerated aging syndrome in which most of the characteristic stages of human senescence are compressed into less than a decade. Defect probably in DNA repair. (18 Nov 1997) |
| premature systole | A premature contraction of the heart that is independent of the normal rhythm and arises in response to an impulse in some part of the heart other than the sinoatrial node. Synonym: premature beat. (18 Nov 1997) |
| premature ventricular contractions | Contractions of the lower chambers of the heart, the ventricles, which occur earlier than usual, because of abnormal electrical activity of the ventricles. The premature contraction is followed by a pause, as the heart electrical system resets itself and the contraction following the pause is usually more forceful than normal. These more forceful contractions are frequently perceived as palpitations. (12 Dec 1998) |
| infant, premature | An infant born before 38 weeks of gestation. (12 Dec 1998) |
| ovarian failure, premature | Premature failure of ovulation associated with hypergonadotropinism and hypoestrogenism in women under the age of 40. The aetiology appears to be multifactorial and many cases are idiopathic. When follicles are present but the ovaries are unable to respond to gonadotropins, resistant ovary syndrome results and this may be associated with autoimmune disease. Even when there is a loss of ovarian follicles, it is not always complete. Permanent and irreversible loss of follicles is termed premature menopause (menopause, premature). (12 Dec 1998) |
| 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) |
| foetal membranes, premature rupture | Spontaneous rupture of amniotic sac before the onset of uterine contractions. (12 Dec 1998) |
| anodal closure contraction | An obsolete term for the momentary contraction of a muscle under the influence of the positive pole when the electrical circuit is established. (05 Mar 2000) |
| anodal opening contraction | An obsolete term for the momentary contraction of a muscle under the influence of the positive pole when the circuit is broken. (05 Mar 2000) |
