Introduction: The second edition of the Movement Assessment Battery for Children (M ABC‐2) is a standardised, norm referenced assessment that is frequently used by therapists to identify children with motor difficulties. The norms for the M ABC‐2 were derived from a sample of children in the United Kingdom (UK) and are combined across the age groups for boys and girls. The aims of this research were to investigate gender differences in the performance of 8‐ and 9‐year‐old Australian children and if the norms in our cohort differed from UK‐based M ABC‐2 norms. Methods: Children aged 8 or 9 years of age who underwent major neonatal cardiac or non‐cardiac surgery and healthy controls were assessed using the M ABC‐2 as part of the Development After Infant Surgery (DAISy) study. Results: There were statistically significant differences in the scores for boys and girls aged 8‐ and 9‐years old on the M ABC‐2. Girls performed better than boys in manual dexterity and on total standard scores. Our control group compared to the assessment norms scored significantly poorer in manual dexterity, aiming and catching and total standard scores. Conclusion: Caution should be used when interpreting the results of the M ABC‐2 for Australian 8‐ and 9‐year olds. Contemporary Australian, gender‐specific M ABC‐2 norms should be considered. Further research is required to investigate gender differences and differences in performance of Australian children compared to the assessment norms in other age groups on the M ABC‐2.

Purpose: The study compared neurodevelopmental outcome at 3 years of age of infants with infantile hypertrophic pyloric stenosis (IHPS) who underwent pyloromyotomy with healthy control infants in New South Wales, Australia.Methods: Infants with IHPS as well as controls were recruited between August 2006 and July 2008. Developmental assessments were performed using the Bayley scales of infant and toddler development (version III) (BSITD-III) at 1 and 3 years of age.Results: Of the 43 infants originally assessed at 1 year, 39 returned for assessment at 3 years (90%). The majority were term infants (77%). Assessments were also performed on 156 control infants. Infants with IHPS scored significantly lower on four of the five Bayley subsets (cognitive, receptive and expressive language and fine motor) compared to control infants. Analysis of co-variance showed statistically significant results in favour of the control group for these four subsets.Conclusion: Compared with the outcomes at 1 year, infants with IHPS at 3 years of age continue to score below controls in four of the BSITD-III subscales. This suggests they should have developmental follow-up with targeted clinical intervention. There is a need for further studies into functional impact and longer term outcomes.

Objective: The objective of this study was to determine whether there remain developmental differences between term infants at 3 years of age following major non-cardiac surgery (NCS) and cardiac surgery (CS) compared with healthy control infants in New South Wales (NSW), Australia.Study Design: Between 2006 and 2008, term infants who required NCS or CS within the first ninety days of life were enrolled in a prospective population-based study. Their developmental outcome was then compared with a cohort of healthy term infants. Infants initially assessed at 1 year of age were then re-assessed at 3 years of age using the Bayley scales of infant and toddler development (version-Iii) Results: Of the 539 term infants assessed at 1 year of age, 417 returned for the 3-year assessment, with 378 complete assessments. The mean scores for the infants who underwent CS (P < 0.001) were significantly lower in all subscales of the assessment compared with the controls, while the mean scores for the infants who underwent NCS were significantly lower in three of the subscales (P < 0.05). The infants who underwent CS scored significantly lower in four of the subscales (P < 0.05), compared with the infants who underwent NCS.Conclusion: The second phase of this unique population-based study provides further data on the outcomes of infants who underwent major NCS and CS. Major surgery in infants continues to be associated with developmental delay at 3 years of age compared with control infants; however the majority of the delay is mild. The risk remains higher in CS group with the pattern and severity of delay similar to that observed in the first study. [ABSTRACT FROM AUTHOR]

Background: Standardised developmental tests are now widely used in neurodevelopmental assessments of infants and children. In 2006, the revised and updated version of the Bayley Scales of Infant and Toddler Development (version III) replaced the previous version and is now widely used in neonatal developmental follow-up clinics. Several papers from Australia have highlighted underestimation of developmental impairment up to age 2 using this revised version. We aimed to ascertain how a cohort of healthy 3-year-old children performed compared to the standardised norms of the Bayley Scales of Infant and Toddler Development (version-III). Method: Term healthy newborn control infants from the prospective Development after Infant Surgery (DAISy) study were included. At 3 years of age, the mean scores on each of the five subscales for 156 children were compared with the standardised norms. Results: At 3 years of age, the mean scores were higher than the standardised norms on four of the subscales, cognition (<0.05), receptive and expressive language and fine motor (p<0.001). There was no significant difference in the gross motor scale (p=0.435). Conclusions: Healthy term Australian children have a statistically significantly higher mean score on the Bayley Scales of Infant and Toddler Development (version-III) compared with the standardised means in four of the subtests, with the greatest difference in receptive language. This has implications for the assessment of children as the test may miss those with a minor delay and not reflect the severity of delay of infants that it does identify. We recommend that consideration ought to be given to re-standardising this assessment on Australian children. [ABSTRACT FROM AUTHOR]

Objectives: When evaluated prospectively, acute brain injury is reported in up to 75% of neonates undergoing cardiopulmonary bypass (CPB), predominantly white matter injury rather than stroke. This study investigates the incidence of stroke (focal infarct and/or haemorrhage) detected by neuroimaging in contemporary clinical practice, whereby magnetic resonance imaging/computed tomography routinely occurs in response to clinical events, comparing those undergoing the Norwood procedure with those undergoing other neonatal procedures involving CPB, and defines the relationship between stroke and neurodevelopmental disability (NDD) at 12 months of age., Methods: One hundred and twenty neonates underwent CPB between July 2011 and December 2014: 25 Norwood procedures and 95 non-Norwood procedures. Data were retrospectively collected including clinical data and 12-month neurodevelopmental assessment using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III)., Results: Stroke was detected in 12% of neonates in current clinical practice: 24% of the Norwood group vs 8% of the non-Norwood group (P = 0.03). Significant predictors of stroke in the univariate analysis included the Norwood procedure, lowest operative temperature and use of extracorporeal membrane oxygenation (P < 0.05). The lowest operative temperature and use of extracorporeal membrane oxygenation remained significant in the multivariate analysis (P < 0.05). Fifty-seven percent were assessed using the BSID-III assessment, and 68% demonstrated NDD in at least 1 subscale. In neonates who suffered stroke, the incidence of NDD was significantly greater in 4/5 subscales compared with those with no injury (P < 0.05). The Norwood group had a significantly greater incidence of NDD in 2/5 subscales when compared with the non-Norwood group (P < 0.05)., Conclusions: Stroke, established by neuroimaging in contemporary clinical practice, was detected in 12% of neonates having CPB, and those undergoing the Norwood procedure have a 3-fold risk of injury. Stroke was associated with NDD at 12 months of age.

Background: We present six cases of infants with Robin sequence and severe obstructive sleep apnoea who failed treatment with nasal mask continuous positive airway pressure (CPAP). Surgical intervention with mandibular distraction osteoneogenesis with glossopexy meant tracheostomy was avoided. Polysomnography (PSG) was used to document the severity of the obstructive sleep apnoea. The aim of this report was to assess the value of mandibular distraction osteogenesis with glossopexy in children with Robin sequence using PSG preoperatively and post-operatively., Methods: Retrospective review of medical records to assess details of preoperative clinical progress, CPAP therapy, endoscopy, PSG and respiratory parameters., Results: Between 2003 and 2008, 20 infants with Robin sequence were admitted to the neonatal intensive care unit of our tertiary paediatric hospital. Six infants (30%) failed a treatment trial of CPAP during that period, but were subsequently successfully managed with mandibular distraction osteoneogenesis and glossopexy. At endoscopy, all had associated airway problems which included congenitally hypoplastic epiglottis (n= 2), laryngomalacia (n= 2), unilateral choanal atresia (n= 1) and long-segment tracheal stenosis (n= 1)., Conclusion: Mandibular distraction osteogenesis with glossopexy provides relief of severe upper airway obstruction for infants with Robin sequence. Epiglottic maldevelopment was present in two infants (33%). Endoscopy and PSG assisted clinical management, but highlighted ongoing respiratory issues., (© 2010 The Authors.
