Objective: The aim of the present prospective cohort study was to evaluate the relationship between lower respiratory tract colonization with Ureaplasma urealyticum and development of chronic lung disease (CLD) in a high-risk neonatal population.Methods: Prospective cohort study of preterm infants with a birthweight < 1,500 g needing mechanical ventilation within 24 h of birth in a tertiary care neonatal unit. Endotracheal aspirates from these infants were cultured within 24 h for U. urealyticum and the rate of colonization was determined. The primary outcome measure was the incidence of CLD at 28 days of life.Results: Of the 41 infants studied, 10 (24%) infants were colonized with U. urealyticum. The colonization rate was higher in babies < 1,000 g compared with babies weighing 1,000-1,500 g (P = 0.04). There was no significant difference between the colonized and non-colonized groups with regard to the antenatal use of steroids, maternal prolonged rupture of membranes, gestational age, birthweight, sex, respiratory distress syndrome, use of surfactant, patent ductus arteriosus and gastrooesophageal reflux. Of the 37 survivors, 20 (54%) developed CLD; eight infants (88.5%) in the colonized group developed CLD compared with 12 infants (42.8%) in the non-colonized group (P = 0.01).Conclusions: Neonates colonized with U. urealyticum were twice as likely to have CLD than non-colonized babies (relative risk 2.01; 95% confidence interval 1.27-3.37). These data suggest a significant association between colonization with U. urealyticum and CLD in infants weighing < 1,500 g. [ABSTRACT FROM AUTHOR]

Cyclopentolate-phenylephrine eye drops are commonly used for mydriasis during routine screening for retinopathy of prematurity in preterm infants. Although systemic absorption is minimal, it can result in side effects. We report two cases of transient paralytic ileus associated with transient oxygen desaturation and hypertension following the use of cyclopentolate-phenylephrine eye drops. [ABSTRACT FROM AUTHOR]

Eight cases of fetal arrhythmia were seen over a 3-year period. Two had atrial and/or ventricular extrasystoles, 1 had complete atrioventricular block and 5 had tachyarrhythmias--3 supraventricular tachycardia, 1 atrial flutter and 1 ectopic atrial tachycardia. All had structurally normal hearts. Nonimmune hydrops fetalis was the initial presentation in 3 of the 5 cases with tachyarrhythmias. There were 2 deaths--a stillbirth and a neonatal death, while 2 others required neonatal intensive care. The 6 survivors have remained well and are now off treatment. The diagnosis, careful assessment and management of a fetal arrhythmia may lead to a successful outcome. The complexity of the problems experienced may warrant early referral to a tertiary centre where the overall management of the mother, fetus and neonate, may be undertaken.
