“…The results are in line with a Danish study that found mean visual acuity in extremely preterm children (Fledelius et al 2015) to be 0.63 and in full-term controls 0.8, at 4 years. The frequency of vision impairment in extremely preterm children has been reported as 2.0-3.1% (Leversen et al 2012;Holmstrom et al 2014, andFledelius et al 2015) compared to our finding of 3.0%. Holmstrom et al (Holmstrom et al 2014) found only 51% of extremely preterm children able to participate in optotype testing at 2.5 years and 32.1% failed optotype testing at 3 years in a recent Dutch study (Telleman et al 2019).…”

Purpose To investigate outcomes of routine vision screening compared to as‐indicated ophthalmological investigation of all children born preterm in a Danish region from 1997 to 2014. Methods All children born preterm (gestation age < 32 weeks or birthweight < 1500 g) screened for retinopathy of prematurity (ROP) were divided into two groups. From 1997 to 2009, only children treated for ROP or referred for visual problems received ophthalmological investigation (as‐indicated group). From 2010 to 2014, all ROP‐screened infants were offered ophthalmological investigation at 6 months and 3 years of age (screening group). Results A total of 560 children were included in the as‐indicated period, 41 and 87 were referred for ophthalmological investigation at 6 months and 3 years, respectively. In the screening period, 295 children were included, 251 and 150 of whom underwent vision evaluation at 6 months and 3 years, respectively. Mean visual acuity was 4.1 cycles per degree with Teller acuity cards at 6 months and 0.78 decimal at 3 years. At 3 years, 2.7%(n = 11) in the as‐indicated versus 3.5%(n = 10) screening group had visual acuity < 6/18 (p = 0.24). Cerebral palsy (n = 28) and epilepsy (n = 5) were significantly related to vision impairment (p = 0.001/0.006), while treated ROP was not (n = 13). Refractive error was common at 3 years (61%), especially astigmatism (50%). Gestational age, birthweight and ROP were not associated with vision impairment or refractive error. Conclusion Screening preterm children at 6 months and 3 years did not reveal more visually impaired children compared to examination when indicated.

“…Single aim Planning articles (Table S7) emphasized financial planning [179–181], motor and mental outcomes [182,183] and economic achievements of persons with CP [184]. Life expectancy for children with CP without severe impairments is marginally less than those without CP, therefore planning for future health, educational, environmental and social needs is a necessity, and one that can increase a person’s ability to be an independent and productive member of society [185].…”

The aims of this study were to provide a comprehensive summary of the body of research disseminated by Cerebral Palsy (CP) registries and surveillance programs from January 2009 through May 2014 in order to describe the influence their results have on our overall understanding of CP. Secondly, registries/surveillance programs and the work they produced were evaluated and grouped using standardized definitions and classification systems.MethodA systematic review search in PubMed, CINAH and Embase for original articles published from 1 January 2009 to 20 May 2014 originating from or supported by population based CP registries and surveillance programs or population based national registries including CP were included. Articles were grouped by 2009 World CP Registry Congress aim, registry/surveillance program classification, geographical region, and the International Classification of Function, Disability and Health (ICF) domain. Registry variables were assessed using the ICF-CY classification.ResultsLiterature searches returned 177 articles meeting inclusion criteria. The majority (69%) of registry/surveillance program productivity was related to contributions as a Resource for CP Research. Prevention (23%) and Surveillance (22%) articles were other areas of achievement, but fewer articles were published in the areas of Planning (17%) and Raising the Profile of CP (2%). There was a range of registry/surveillance program classifications contributing to this productivity, and representation from multiple areas of the globe, although most of the articles originated in Europe, Australia, and Canada. The domains of the ICF that were primarily covered included body structures and function at the early stages of life. Encouragingly, a variety of CP registry/surveillance program initiatives included additional ICF domains of participation and environmental and personal factors.InterpretationCP registries and surveillance programs, including novel non-traditional ones, have significantly contributed to the understanding of how CP affects individuals, families and society. Moving forward, the global CP registry/surveillance program community should continue to strive for uniformity in CP definitions, variables collected and consistency with international initiatives like the ICF so that databases can be consolidated for research use. Adaptation to new technologies can improve access, reduce cost and facilitate information transfer between registrants, researchers and registries/surveillance programs. Finally, increased efforts in documenting variables of individuals with CP into adulthood should be made in order to expand our understanding of CP across the lifespan.

“…However, like preterm infants, those with SSC represent a group at particularly high risk of developmental concerns, with 40% or more showing signs of delay or impairment by 3 years of age, and nearly half with learning, developmental, or behavioral problems upon school entry . A number of previous studies support the notion that such problems can be predicted using infant and toddler developmental assessments . Moreover, children with SSC have early and frequent contact with the healthcare system, as most are diagnosed in the first months of life, undergo surgery by age 12 months, and receive follow‐up medical examinations throughout their preschool years.…”

AIM The aim of this study was to determine whether neurobehavioral assessment before and after cranial vault surgery can improve prediction of developmental delay in children with single-suture craniosynostosis (SSC), after accounting for clinical (SSC diagnosis and surgery age) and demographic ‘baseline’ variables. METHOD Children with SSC were referred by the treating surgeon or pediatrician before surgery. Neurobehavioral assessments were performed at ages of approximately 6, 18, and 36 months. Iterative models were developed to predict delay, as determined by one or more tests of cognitive, motor, and language skills at 36 months. We selected from groups of variables entered in order of timing (before or after corrective surgery), and source of information (parent questionnaire or psychometric testing). RESULTS Good predictive accuracy (as determined by area under the receiver operating characteristic curve [AUC]) was obtained with the baseline model (AUC=0.66), which incorporated age at surgery, sex, and socio-economic status. However, predictive accuracy was improved by including pre- and post-surgery neurobehavioral assessments. Models incorporating post-surgery neurobehavioral testing (AUC=0.79), pre-surgery testing (AUC=0.74), or both pre- and post-surgery testing (AUC=0.79) performed similarly. However, the specifity of all models was considered to be moderate (≤0.62). INTERPRETATION Prediction of delay was enhanced by assessment of neurobehavioral status. Findings provide tentative support for guidelines of care that call for routine testing of children with SSC.
