| mortality rate, neonatal | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |
|---|---|
| neonatal | <paediatrics> Pertaining to the first four weeks after birth. Origin: L. Natus = born (18 Nov 1997) |
| neonatal abstinence syndrome | <syndrome> Foetal and neonatal addiction and withdrawal as a result of the mother's dependence on drugs during pregnancy. Withdrawal or abstinence symptoms develop shortly after birth. Symptoms exhibited are loud, high-pitched crying, sweating, yawning and gastrointestinal disturbances. (12 Dec 1998) |
| neonatal anaemia | <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) |
| neonatal apoplexy | Intracranial haemorrhage in newborn children. (05 Mar 2000) |
| neonatal arthritis of foals | Bacterial polyarthritis caused by umbilical infections by several bacterial species. (05 Mar 2000) |
| neonatal calf diarrhoea virus | One of two virus's causing neonatal calf diarrhoea; a reovirus-like virus is associated with disease in newborn calves, and a coronavirus is associated with disease in calves over 5 days of age. (05 Mar 2000) |
| neonatal conjunctivitis | Acute conjunctival inflammation in the newborn, usually caused by maternal gonococcal infection. The causative agent is neisseria gonorrhoeae. The baby's eyes are contaminated during passage through the birth canal. (12 Dec 1998) |
| neonatal death | Death of a young, liveborn infant; classified as: (05 Mar 2000) |
| neonatal diagnosis | Systematic evaluation of the newborn for evidence of disease or malformations, and the conclusion reached. (05 Mar 2000) |
| neonatal diseases and abnormalities | Diseases existing at birth and often before birth, regardless of causation. Of these congenital diseases, those characterised by structural deformities are termed abnormalities. (12 Dec 1998) |
| neonatal heart failure | <radiology> most likely cause, premature: patent ductus arteriosus, full term: hypoplastic left heart, 2nd week: coarctation and VSD aetiology, valvular stenosis, mitral stenosis, aortic stenosis, aortic coarctation, vein of Galen aneurysm, infantile haemangioendothelioma of liver, hypoplastic left heart see also: congestive heart failure in kids (12 Dec 1998) |
| neonatal hepatitis | Hepatitis in the neonatal period presumed to be due to a variety of causes, chiefly viral; characterised by direct and indirect bilirubinaemia, hepatocellular degeneration, and appearance of multinucleated giant cells; may be difficult to distinguish from biliary atresia, but is more likely to end with recovery, although cirrhosis may develop. Synonym: giant cell hepatitis. (05 Mar 2000) |
| neonatal herpes | Herpes simplex virus type 1 or 2 infection transmitted from the mother to the newborn infant, often during passage through an infected birth canal; severity varies from mild to fatal generalised infection, the latter especially with primary maternal genital herpes. (05 Mar 2000) |
| neonatal hypoglycaemia | Familial onset of symptomatic hypoglycaemia during infancy, with persistently low blood glucose; a variant form is leucine-induced with hyperinsulinism and variable mental retardation. (05 Mar 2000) |
