    Notes: Abstract A total of 484 premature children and a control group of 114 healthy term children underwent orthopaedic follow-up from birth to 5 years of age. At birth, metatarsus adductus was found to be more frequent in twins than in single infants (41% vs 16%; P〈0.01), but occurred with equal frequency in single preterm and term infants (16% vs 12%). By 5 years of age, metatarsus adductus had resolved in all the term but only in 81% of the preterm children (P〈0.05). In the preterm and term groups, knee axis (mean intermalleolar distance 22.0 mm vs 20.1 mm), tibial torsion (mean angle-1.2° vs +0.6°) and angle of gait (mean angle +1.5° vs +0.7°) at 5 years were statistically insignificant. Hip function at 5 years was similar in normal preterm and term children but significantly decreased in preterm children with cerebral palsy, more so with regard to abduction (56° vs 39°, P〈0.05) and extension (22° vs 8°, P〈0.01). The difference between the sexes was insignificant in both the preterm and term groups.

    Notes: Abstract Cerebral blood flow (CBF) studies have provided some insight into pathophysiological mechanisms of cerebral damage in newborn children; their value in predicting brain damage, however, remains elusive. The purpose of our study was to evaluate the role of CBF measurements in predicting developmental outcome in preterm neonates at 18 months. Preterm babies with a gestational age of less than 34 weeks and a birth weight of less than 1500 g (n = 71) were enrolled in the study. CBF was measured by the nonivasive intravenous 133Xe method on three different occasions. We classified our measurements into three groups: depending on the time when performed group 1: between 2 and 36 h (n = 52); group 2: between 36 and 108 h (n = 44); group 3: between 108 and 240 h (n = 41). At the age of 18 months neurodevelopment testing was performed according to the Bayley mental and motor scales. Surviving infants had a higher mean CBF over the three groups than non surviving children (15.2 ± 3.5 ml/100 g brain tissue/min vs 13.0 ± 2.1 ml/100 g brain tissue/min, P 〈 0.05). There was no correlation of CBF with mental or motor development in our study population in either of the three groups. Conclusion In preterm infants basal CBF is higher in surviving than in non surviving infants, but there is no correlation of resting CBF and later neurological outcome.
