| 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 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) |
| neonatal isoerythrolysis | Isoerythrolysis in the newborn animal, haemolytic icterus of the newborn. (05 Mar 2000) |
| neonatal jaundice | Icterus which can be accentuated by many factors including excessive haemolysis, sepsis, neonatal hepatitis or congenital atresia of the biliary system. Synonym: physiologic icterus, jaundice of the newborn, neonatal jaundice, physiologic jaundice. (05 Mar 2000) |
| neonatal line | In deciduous teeth, a line of demarcation between prenatal and postnatal enamel. Synonym: neonatal ring. (05 Mar 2000) |
