| foetal erythroblastosis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
|---|---|
| foetal face syndrome | <syndrome> A syndrome of facies resembling an early foetus with short forearms, and genital hypoplasia at birth, but without evidence of achondroplasia; leads to dwarfism without mental retardation. Synonym: Robinow's syndrome. (05 Mar 2000) |
| foetal fracture | A fracture of one or more bones of a foetus occurring before birth. Synonym: foetal fracture. (05 Mar 2000) |
| foetal gigantism | Excessive foetal or newborn size, e.g., cerebral gigantism and infants of diabetic mothers. (05 Mar 2000) |
| foetal growth retardation | The failure of a foetus to maintain its expected growth potential at any gestational stage. (12 Dec 1998) |
| foetal habitus | Relationship of one foetal part to another. Synonym: foetal attitude. (05 Mar 2000) |
| foetal haemoglobin | <chemical> The form of haemoglobin normally comprising more than half of the haemoglobin in the foetus, composed of two alpha and two gamma polypeptides. It is also present in minimal amounts in adulthood and is abnormally elevated in aplastic anaemia, leukaemia, and certain types of thalassaemia. It has higher affinity for oxygen under physiologic conditions than does haemoglobin a. Chemical name: Haemoglobin F (12 Dec 1998) |
| foetal heart | The heart of the foetus of any viviparous animal. It refers to the heart in the postembryonic period and is differentiated from the embryonic heart (heart/embryology) only on the basis of time. (12 Dec 1998) |
| foetal hydantoin syndrome | <syndrome> A foetal syndrome resulting from maternal ingestion of hydantoin analogues (e.g., phenytoin), characterised by growth deficiency, mental deficiency, dysmorphic facies, cleft palate and/or lip, cardiac defects, and abnormal genitalia. (05 Mar 2000) |
| foetal hydrops | <radiology> Immune, Rh sensitization (erythroblastosis foetalis), non-immune, thalassaemia, structural defects (e.g., lung tumour), cardiac arrhythmia (secondary to conduction defect), ultrasound findings: foetal ascites and/or pleural or pericardial effusion, subcutaneous oedema, polyhydramnios, thick, hydropic placenta (12 Dec 1998) |
| foetal inclusion | Unequal conjoined twins in which the incompletely developed parasite is wholly enclosed in the autosite. (05 Mar 2000) |
| foetal macrosomia | A complication of gestational diabetes mellitus or prolonged pregnancy. A macrosomic foetus is defined as weighing more than 4000 grams. (12 Dec 1998) |
| foetal medicine | Study of the growth, development, care, and treatment of the foetus, and of environmental factors harmful to the foetus. Synonym: fetology. (05 Mar 2000) |
| foetal membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| foetal membranes | Thin layers of tissue which surround the embryo or foetus and provide for its nutrition, respiration, excretion and protection; they are the yolk sac, allantois, amnion, and chorion. (12 Dec 1998) |
