| newborn jaundice | <paediatrics> A normal condition of elevated bilirubin in the bloodstream of a newborn. This occurs secondary to immaturity of liver cells (cannot effectively metabolise bilirubin) and the increased destruction of red blood cells (further releasing bilirubin into the bloodstream) that is normally seen in the newborn. The jaundice usually appears between the 2nd and 5th days of life and usually clears by 2 weeks. Other factors which can potentiate jaundice in the newborn include: sepsis, biliary atresia, Rhesus incompatibility, galactosaemia, cephalohaematoma, polycythaemia, G-6-P-D deficiency and congenital rubella, syphilis, toxoplasmosis or cytomegalovirus infection.

| newborn screening | Tests of newborns to detect those at increased risk for disorders such as pku (phenylketonuria) and hypothyroidism. (12 Dec 1998) |
| subcutaneous fat necrosis of newborn | Indurated plaques and nodules appearing usually a few days or a few weeks after birth and usually resolving within a few months, characterised microscopically by birefringent needle-shaped crystals within necrotic fat cells; the condition remains localised, unlike sclerema neonatorum. (05 Mar 2000) |
| disease, haemolytic, of the newborn | Abnormal breakup of red blood cells in the foetus or newborn. (12 Dec 1998) |
| jaundice of the newborn | 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) |
| leukocytosis of the newborn | An apparently "physiologic" leukocytosis usually observed in newborn infants, in whom the white blood cell counts are usually greater than 10,000 per cu mm, and sometimes range to 45,000 per cu mm, resulting chiefly from increased numbers of neutrophils (especially single and bilobed forms). On the third or fourth day of life, the count generally decreases rapidly, and then fluctuates for several days; beginning about the fourth week of life, a relative lymphocytosis is observed, and this normally continues for a few years.

| Bayley Scales of Infant Development | A psychological test used to measure the developmental progress of infants over the first two and one-half years of life; consists of three scales: mental, motor, and behaviour record. (05 Mar 2000) |
| rate, infant mortality | The number of children dying under a year of age divided by the number of live births that year. The infant mortality rate in the united states, which was 12.5 per 1,000 live births in 1980, fell to 9.2 per 1,000 live births in 1990. (12 Dec 1998) |
| Cattell Infant Intelligence Scale | A standardised scale for assessment of the cognitive development of infants between the ages of 3 and 30 months. (05 Mar 2000) |
| mortality rate, infant | The number of children dying under a year of age divided by the number of live births that year. The infant mortality rate in the united states, which was 12.5 per 1,000 live births in 1980, fell to 9.2 per 1,000 live births in 1990. (12 Dec 1998) |
| postmature infant | A baby born 1 week (7 days) or more after the usual 9 months (280 days) of gestation. (12 Dec 1998) |
| post-term infant | A baby born 2 weeks (14 days) or more after the usual 9 months (280 days) of gestation, as calculated from the last menstrual period (lmp). This is an important calculation, since, if delivery is delayed 3 weeks beyond term, the infant mortality rate skyrockets to 3 times normal. (12 Dec 1998) |
| preterm infant | An infant with gestational age of less than 37 completed weeks (259 completed days). (05 Mar 2000) |
| stillborn infant | An infant who shows no evidence of life after birth. Compare: liveborn infant. (05 Mar 2000) |
