| brain death | Total cessation of brain function for 24 hours as manifested by absence of spontaneous movement, absence of spontaneous respiration, and absence of all brainstem reflexes. (12 Dec 1998) |
|---|---|
| genetic death | Death of the bearer of a gene at any age before generating living offspring. May be compatible with good health and long life. See: genetic lethal. (05 Mar 2000) |
| maternal death | Death of a woman while pregnant or within 42 days after the termination of gestation, irrespective of the duration and site of pregnancy and the cause of death; two periods are recognised in the 42-day interval: period 1 includes day 1 to day 7; period 2 includes day 8 to day 42. Maternal death's are further classified as: (05 Mar 2000) |
| cause of death | Factors which produce cessation of all vital bodily functions. They can be analyzed from an epidemiologic viewpoint. (12 Dec 1998) |
| cell death | <cell biology> Cells die (nonaccidentally) either when they have completed a fixed number of division cycles (around 60, the Hayflick limit) or at some earlier stage when programmed to do so, as in digit separation in vertebrate limb morphogenesis. Whether this is due to an accumulation of errors or a programmed limit is unclear, some transformed cells have undoubtedly escaped the limit. See: apoptosis. (26 Mar 1998) |
| cerebral death | A clinical syndrome characterised by the permanent loss of cerebral and brain stem function, manifested by absence of responsiveness to external stimuli, absence of cephalic reflexes, and apnea. An isoelectric electroencephalogram for at least 30 minutes in the absence of hypothermia and poisoning by central nervous system depressants supports the diagnosis. Synonym: brain death. (05 Mar 2000) |
| perinatal death | An inclusive term referring to both stillborn infants and neonatal death's. (05 Mar 2000) |
| mitotic death | <cell biology> Cells fatally damaged by ionising radiation may not die until the next mitosis, at which point the radiation damage to the DNA becomes evident, particularly when there is fragmentation of chromosomes. (18 Nov 1997) |
| cot death | <syndrome> May affect infants of any age, but some risk factors have been identified: term infants who have had a life-threatening period of apnoea (not breathing), premature infants of low birth weight, siblings of infants who have succumbed to sudden infant death syndrome and infants of substance abusing mothers. Peak age is at 2.5 months and 4 months, but can range from 1 month to 1 year. High risk infants should have home monitoring done. It is recommended that the less than 4 month old infant should sleep on their back. Synonym: cot death syndrome. Incidence: 2 per 1,000 live births. Acronym: SIDS (27 Sep 1997) |
| crib death | <syndrome> May affect infants of any age, but some risk factors have been identified: term infants who have had a life-threatening period of apnoea (not breathing), premature infants of low birth weight, siblings of infants who have succumbed to sudden infant death syndrome and infants of substance abusing mothers. Peak age is at 2.5 months and 4 months, but can range from 1 month to 1 year. High risk infants should have home monitoring done. It is recommended that the less than 4 month old infant should sleep on their back. Synonym: cot death syndrome. Incidence: 2 per 1,000 live births. Acronym: SIDS (27 Sep 1997) |
| programmed cell death | <cell biology, molecular biology> The concept that certain cells are determined to die at specific stages and specific sites during development, for example cells in the spaces between the developing digits of vertebrates, thus dividing them. Programmed cell death occurs by apopotosis. (18 Nov 1997) |
| somatic death | Death of the entire body, as distinguished from local death. (05 Mar 2000) |
| neonatal death | Death of a young, liveborn infant; classified as: (05 Mar 2000) |
| sudden death | An arrhythmogenic death in aortic stenosis, coronary disease, mesothelioma of the AV node, or single coronary artery. (05 Mar 2000) |
| sudden infant death | The abrupt and unexplained death of an apparently healthy infant under one year of age, remaining unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history. (expert panel of the national institute of child health and human development in paediatric pathology, v.11, no.5, sept-oct 1991, p681) (12 Dec 1998) |
