Necrotizing enterocolitis (NEC) affects mainly preterm infants, has a multifactorial etiology and is associated with intestinal dysbiosis and disordered immunity. Use of probiotics for prophylaxis is beneficial with studies indicating reduction in NEC ≥ stage 2, late onset sepsis (LOS) and mortality. However, not all studies have shown a reduction, there are questions regarding which probiotic to use, whether infants <1,000 g benefit and the risk of probiotic sepsis.

This study examined the natural history of this acidosis in a population of infants of gestation less than 26 weeks in the first 14 days of life. The acidosis was maximal on day 4 with a mean base deficit of 10.

The relationship between the plasma aldosterone level and a number of clinical and biochemical variables was explored. Plasma aldosterone levels ranged from 1000 to 30000 pmol/l and were inversely correlated with the severity of illness (D1 or D7), serum sodium (D7) and 24 h sodium intake (D1).

Two cases of hyponatraemic hypertensive syndrome occurring in extremely low birthweight infants are presented. Both infants experienced unilateral renal ischaemia resulting in hyponatraemia and hypertension. A proposed pathophysiological mechanism, namely unilateral renal ischaemia leading to a pressure-natriuresis in the contralateral kidney, is presented.

Aim: To compare the efficacy of hydrocortisone with dopamine for the treatment of hypotensive, very low birthweight (VLBW) infants.
Methods: Forty infants were randomly allocated to receive either hydrocortisone (n = 21) or dopamine (n = 19).
Results: All 19 infants randomised to dopamine responded; 17 of 21 (81%) did so in the hydrocortisone group.
Infants of very low birthweight (VLBW) who underwent thoracotomy were given 2.0 mg.kg-1 of bupivacaine by the intrapleural route, and serial blood levels were taken to determine the pharmacokinetic profile in this group of babies.

Aims: To assess the impact, mortality, morbidity and economic costs, of respiratory distress syndrome severe enough to warrant ventilation in one year in New Zealand.
Methods: Review of data from all five New Zealand regional neonatal intensive care units' participation in the international OSIRIS trial of exogenous surfactant (Exosurf) treatment for respiratory distress syndrome (involving 6700 infants in 21 countries), and extrapolation of these data to a full year.
Results: There were 265 New Zealand infants entered in the OSIRIS trial; the mean birthweight was 1335 g and mean gestation 29 weeks; 61% of infants were less than 30 weeks gestation.
The incidence, aetiologic organism and mortality associated with neonatal septicaemia were retrospectively reviewed over a seven year period (June 1983 to July 1990). Trends with time were evaluated by dividing the study period in half. Although there was no significant change in the incidence of septicaemia during the study period (3.

The effect of a 21-day (reducing dose) course of dexamethasone upon platelet numbers, neutrophil numbers and neutrophil morphology in ventilator-dependent preterm infants with chronic lung disease is reported. Forty-one infants, who were sepsis-free throughout the treatment period, received 46 courses of dexamethasone. In these infants the circulating platelet count increased significantly from 235 +/- 157 to 476 +/- 208 X 10(9)/L.

There were 367 operations performed on 296 infants aged 0-28 days, with 144 of the operations being classified as a major. Of the 31 deaths, three occurred preoperatively and 28 postoperatively, with diaphragmatic hernia (n = 8) and necrotising enterocolitis (n = 7) being the commonest causes.

Despite this, prophylactic administration of Vitamin K1 remains controversial and haemorrhagic disease of the newborn continues to cause significant morbidity and mortality. We present two cases of this disease occurring recently in this region of New Zealand; one resulting in an infant's death, the other baby suffering from an intraventricular haemorrhage and secondary hydrocephalus.

All infants survived; although only two were neurologically intact.
