| 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 contraction | <cardiology> A cardiac arrhythmia which originates from within the ventricles. Isolated ventricular contractions are referred to as premature ventricular contractions. Frequent premature ventricular contractions can be potentially unstable and can degrade to a more serious rhythm or cardiac arrest. Acronym: PVC (31 Dec 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) |
| alopecia | 1. <dermatology> Baldness, absence of the hair from skin areas where it normally is present. 2. <oncology> Hair loss as a result of chemotherapy or radiation therapy administered to the head. Hair loss from chemotherapy is temporary. Hair loss from radiation is usually permanent. Origin: Gr. Alepekia = a disease in which the hair falls out (14 May 1997) |
| alopecia adnata | Underdevelopment of the lashes. See: alopecia congenitalis. Synonym: madarosis. (05 Mar 2000) |
| alopecia areata | <dermatology> A patchy baldness usually of a temporary nature. Cause unknown but anxiety and stress are common precipitating factors. (27 Sep 1997) |
| alopecia cicatrisata | Synonym: scarring alopecia. Origin: L. Cicatrix, cicatricis, scar + suffix -al, characterised by (05 Mar 2000) |
| alopecia congenitalis | Absence of all hair at birth, associated with psychomotor epilepsy; autosomal dominant inheritance. Synonym: congenital baldness, hypotrichiasis. (05 Mar 2000) |
| alopecia disseminata | Loss of hair from all parts of the body. (05 Mar 2000) |
| alopecia leprotica | Thinning or total loss of the lateral third of the eyebrows, eyelashes, and body hairs, seen in leprosy; loss of scalp hair is rare. (05 Mar 2000) |
| alopecia marginalis | Hair loss at the hair line, a condition most commonly seen in blacks; commonly transient and caused by chronic traction, although long-continued traction may cause permanent alopecia. Synonym: alopecia liminaris frontalis. (05 Mar 2000) |
