| dead foetus syndrome | <obstetrics, syndrome> A syndrome characterised by lengthy intrauterine retention of a dead foetus usually greater than 4 weeks with development of hypofibrinogenaemia and occasionally disseminated intravascular coagulopathy. (05 Mar 2000) |

| campylobacter foetus | A species of bacteria present in man and many kinds of animals and birds, often causing infertility and/or abortion. (12 Dec 1998) |
| Campylobacter foetus jejuni | Former name for Campylobacter jejuni. (05 Mar 2000) |
| Campylobacter foetus venerealis | A subspecies causing a venereal disease of cattle characterised by infertility and early embryonic death. (05 Mar 2000) |
| Vibrio foetus | <bacteria> Former name for Campylobacter foetus. (05 Mar 2000) |
| harlequin foetus | A severe autosomal recessive form of collodian baby in a newborn, usually premature, infant; i.e., a form of ichthyosiform erythroderma characterised by encasement of the body in grayish brown, often fissured plaques resembling plates of armor, and by grotesque deformity of the face, hands, and feet; usually fatal within a few days, although treatment with 13-cis-retinoic acid has been successful in some cases. Synonym: ichthyosis foetalis. (05 Mar 2000) |
| impacted foetus | A foetus which, because of its large size or narrowing of the pelvic canal, has become wedged and incapable of spontaneous advance or recession. (05 Mar 2000) |
| Trichomonas foetus | Former name for Tritrichomonas foetus. (05 Mar 2000) |
| tritrichomonas foetus | A species of flagellate parasitic protozoa. It possesses a long undulating membrane that is bordered on its outer margin by a flagellum that becomes free posteriorly. This organism causes infections in cows that could lead to temporary infertility or abortion. (12 Dec 1998) |
| foetus | <biology, embryology, obstetrics> A developing unborn offspring of an animal that gives birth to its young (as opposed to laying eggs). From approximately three months after conception the offspring take on a recognisable form (all parts in place, etc.). In human development, the period after the seventh or eighth week of pregnancy is the foetal period. (12 Nov 1997) |
| foetus in fetu | Condition in which a small, imperfectly formed foetus is contained within a foetus. (05 Mar 2000) |
| foetus papyraceus | One of twin foetus's that has died and been pressed flat against the uterine wall by the growth of the living foetus. (05 Mar 2000) |
| foetus sanguinolentis | Dead foetus that has become macerated. (05 Mar 2000) |
| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
