Objectives: The Gaps in the Congenital Diaphragmatic Hernia (CDH) Journey Priority Setting Partnership (PSP) was developed in collaboration with CDH Australia, James Lind Alliance (JLA) and the Murdoch Children's Research Institute to identify research priorities for people with CDH, their families and healthcare workers in Australasia., Design: Research PSP in accordance with the JLA standardised methodology., Setting: Australian community and institutions caring for patients with CDH and their families., Patients: CDH survivors, families of children born with CDH (including bereaved) and healthcare professionals including critical care physicians and nurses (neonatal and paediatric), obstetric, surgical, allied health professionals (physiotherapists, speech pathologists and speech therapists) and general practitioners., Main Outcome Measure: Top 10 research priorities for CDH., Results: 377 questions, from a community-based online survey, were categorised and collated into 50 research questions. Through a further prioritisation process, 21 questions were then discussed at a prioritisation workshop where they were ranked by 21 participants (CDH survivors, parents of children born with CDH (bereaved and not) and 11 multidisciplinary healthcare professionals) into their top 10 research priorities., Conclusion: Stakeholders' involvement identified the top 10 CDH-related research questions, spanning from antenatal care to long-term functional outcomes, that should be prioritised for future research to maximise meaningful outcomes for people with CDH and their families., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: Describe the intelligence quotient (IQ) of children with Pierre Robin sequence (PRS)., Design: Prospective cohort study., Setting: Neurodevelopmental follow-up clinic within a hospital., Patients: Children with PRS (n = 45) who had been in the Neonatal Intensive Care Unit (NICU) were classified by a geneticist into 3 subgroups of isolated PRS (n = 20), PRS-plus additional medical features (n = 8), and syndromic PRS (n = 17) based on medical record review and genetic testing., Main Outcome Measure: Children with PRS completed IQ testing at 5 or 8 years of age with the Wechsler Preschool and Primary Scale of Intelligence, Third Edition (WPPSI-III) or Fourth Edition (WPPSI-IV) or the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) or Fifth Edition (WISC-V)., Results: IQ scores were more than 1 to 2 standard deviations below the mean for 36% of the overall sample, which was significantly greater compared to test norms (binomial test P  = .001). There was a significant association between PRS subtype and IQ (Fisher's exact P  = .026). While only 20% of children with isolated PRS were within 1 standard deviation below average and 35% of children with syndromic PRS were below 1 to 2 standard deviations, 75% of PRS-plus children scored lower than 1 to 2 standard deviations below the mean., Conclusion: PRS subgroups can help identify children at risk for cognitive delay. The majority of children with PRS-plus had low intellectual functioning, in contrast to the third of children with syndromic PRS who had low IQ and the majority of children with isolated PRS who had average or higher IQ., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Children with neurofibromatosis type 1 (NF1) often experience executive dysfunction, attention deficit/hyperactivity disorder (ADHD) symptoms and poor social skills, however, the nature of the relationships between these domains in children with NF1 is unclear. This study investigated these relationships using primary caregiver ratings of executive functions, ADHD symptoms and social skills in children with NF1. Participants were 136 children with NF1 and 93 typically developing (TD) controls aged 3-15 years recruited from 3 multidisciplinary neurofibromatosis clinics in Melbourne and Sydney, Australia, and Washington DC, USA. Mediation analysis was performed on primary outcome variables: parent ratings of executive functions (Behavior Rating Inventory of Executive Function, Metacognition Index), ADHD symptoms (Conners-3/Conners ADHD Diagnostic and Statistical Manual for Mental Disorders Scales) and social skills (Social Skills Improvement System-Rating Scale), adjusting for potential confounders (full scale IQ, sex, and social risk). Results revealed significantly poorer executive functions, elevated ADHD symptoms and reduced social skills in children with NF1 compared to controls. Poorer executive functions significantly predicted elevated ADHD symptoms and poorer social skills. Elevated ADHD symptoms significantly mediated the relationship between executive functions and social skills problems although did not fully account for social dysfunction. This study provides evidence for the importance of targeting ADHD symptoms as part of future interventions aimed at promoting prosocial behaviors in children with NF1.

Purpose: To characterize cognitive, academic, and behavioral functioning in children who underwent neonatal surgical repair of esophageal atresia (OA) and compare outcomes according to clinical characteristics (presence of additional congenital anomalies, longer hospitalization, and prematurity)., Methods: Intellectual, language, attention, and executive functioning were assessed in 71 5-year-olds and 72 8-year-olds born with OA. At 8 years, memory and academic skills were also assessed. Parents rated children's executive functioning and behavior via questionnaires. Outcomes were compared to normative data and within subgroups of the sample., Results: Intellectual functioning varied depending on the assessment tool, with some evidence of lower than expected intellectual development in children with OA. At 5 years, children with OA showed age-appropriate language and self-regulation, but reduced verbal attention. At 8 years, the OA group had lower than expected sustained attention, divided attention, and mathematics but typical memory and literacy. Parents consistently reported increased working memory difficulties. Other executive functioning and behavioral symptoms were transiently observed. Findings did not consistently differ according to clinical characteristics., Conclusions: Children with OA may be at risk of transient and persisting cognitive difficulties, particularly in attention and working memory. Difficulties were not strongly associated with additional congenital anomalies, longer hospitalization, or prematurity., Level of Evidence: Level IV., (Crown Copyright © 2021.

Objective: Vein of Galenaneurysmal malformation (VGAM) is a rare but important congenital malformation presenting to neonatal intensive care units (NICUs), and with a change from surgical to endovascular management, survival for this condition has improved. However, there is little reported about the medical management decisions of infants with this condition and the associated long-term neurodevelopmental outcomes. We aim to report a single centre experience of both acute treatment and long-term outcomes of VGAM for those infants admitted to our NICU soon after birth., Design: Retrospective cohort study over a 15-year period from 2001 to 2015 inclusive., Setting: A quaternary NICU at The Royal Children's Hospital, Melbourne, Australia., Participants: 24 newborn infants referred for management of VGAM. There were no eligibility criteria set for this study; all presenting infants were included., Interventions: None., Main Outcomes Measures: Clinical neuroimaging data were gathered. Surviving children were formally assessed with a battery of tests administered by a neuropsychologist and occupational therapist/physiotherapist at various ages across early to middle childhood., Results: Fifteen neonates with VGAM did not survive beyond their NICU admission. 10 of these were not offered endovascular intervention. Of the nine surviving infants, only one had a normal neurodevelopmental outcome., Conclusions: The mortality of VGAM presenting in the neonatal period was high, and rates of normal neurodevelopmental outcome for survivors were low. These findings contribute to our understanding of which neonates should be treated and highlights the importance of providing clinical neurodevelopmental follow-up to survivors beyond their infant years., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objective: Previous outcome reports of congenital diaphragmatic hernia (CDH) have described neuroimaging anomalies and neurodevelopmental impairment. However, the link between imaging and outcome has not been described. We aimed to determine whether routine postoperative neonatal neuroimaging in infants with CDH detects later neurodevelopmental impairment., Methods: In a prospective cohort study within a clinical service in The Royal Children's Hospital Newborn Intensive Care. Cerebral ultrasound was performed in 81 children and MRI in 57 children who subsequently underwent neurodevelopmental follow-up after surgery for CDH. MRI scans were analyzed using a scoring system designed to identify injury, maturation and volume loss. Neurodevelopmental assessment occurred at 2 years (48) and neurocognitive assessment at 5 years (26) and/or 8 years (27). Brain imaging scores corrected for gestational age at scan time were correlated with outcome measures, adjusting for known clinical confounders., Results: Clinically significant findings were identified on MRI of 16 (28%) infants. Mean scores were in the normal range for all domains assessed at each age. Language impairment was seen in 23% at 2 years and verbal intellectual impairment in 25% at 8 years. Mean cognitive scores were lower in 2-year-old children with white matter injury on MRI (p=0.03). Mean motor scores were lower in 2-year-old children with brain immaturity (p=0.01). Associations between MRI and 5-year and 8-year assessments were no longer significant when adjusting for known clinical confounders., Conclusions: Neuroimaging abnormalities were associated with worse neurodevelopment at 2 years, but not with later neurocognitive outcomes, after accounting for clinical risk factors., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

In light of the proliferation of recent research into social function in neurofibromatosis type 1 (NF1), a systematic review and meta-analysis is required to synthesise data and place findings within the context of a theoretical framework. This paper reviews findings from research into social function and autism spectrum disorder (ASD) in children and adults with NF1 and integrates these findings with the Socio-Cognitive Integration Abilities Model (SOCIAL). It also critically appraises links between social outcomes, internal and external factors moderating social functioning, cognitive domains implicated in social functioning, and underlying neural pathology in NF1. A systematic literature search conducted in MedLine (Ovid), PsycINFO (Ovid), Embase (Ovid), and PubMed electronic databases yielded 35 papers that met inclusion criteria for the systematic review. Out of these papers, 22 papers provided sufficient data for meta-analysis. Findings from this review and meta-analysis provide evidence that children and adults with NF1 exhibit significantly higher prevalence and severity of social dysfunction and ASD symptomatology. To date, very few studies have examined social cognition in NF1 but results indicate the presence of both perceptual and higher-level impairments in this population. The results of this review also provide support for age, gender, and comorbid ADHD as moderating factors for social outcomes in NF1. Suggestions for future research are offered to further our understanding of the social phenotype in NF1 and to facilitate the development of targeted interventions.

Introduction: Dopamine dysregulation has been identified as a key modulator of behavioural impairment in neurofibromatosis type 1 (NF1) and a potential therapeutic target. Preclinical research demonstrates reduced dopamine in the brains of genetically engineered NF1 mouse strains is associated with reduced spatial-learning and attentional dysfunction. Methylphenidate, a stimulant medication that increases dopaminergic and noradrenergic neurotransmission, rescued the behavioural and dopamine abnormalities. Although preliminary clinical trials have demonstrated that methylphenidate is effective in treating attention deficit hyperactivity disorder (ADHD) symptoms in children with NF1, its therapeutic effect on cognitive performance is unclear. The primary aim of this clinical trial is to assess the efficacy of methylphenidate for reducing attention deficits, spatial working memory impairments and ADHD symptoms in children with NF1., Methods and Analysis: A randomised, double-blind, placebo-controlled trial of methylphenidate with a two period crossover design. Thirty-six participants with NF1 aged 7-16 years will be randomised to one of two treatment sequences: 6 weeks of methylphenidate followed by 6 weeks of placebo or; 6 weeks of placebo followed by 6 weeks of methylphenidate. Neurocognitive and behavioural outcomes as well as neuroimaging measures will be completed at baseline and repeated at the end of each treatment condition (week 6, week 12). Primary outcome measures are omission errors on the Conners Continuous Performance Test-II (attention), between-search errors on the Spatial Working Memory task from the Cambridge Neuropsychological Test Automated Battery (spatial working memory) and the Inattentive and Hyperactivity/Impulsivity Symptom Scales on the Conners 3-Parent. Secondary outcomes will examine the effect of methylphenidate on executive functions, attention, visuospatial skills, behaviour, fine-motor skills, language, social skills and quality of life., Ethics and Dissemination: This trial has hospital ethics approval and the results will be disseminated through peer-reviewed publications and international conferences., Trial Registration Number: ACTRN12611000765921., Competing Interests: Competing interests: DRC has received grants and personal fees from Shire Pharmaceutical Company and Vifor Pharma; personal fees from Janssen-Cilag, Eli Lilly, Novartis, Flynn Pharma, Medice Arzneimittel Pütter and Oxford University Press outside the submitted work.

Studies investigating the neuropsychological functioning of children who experience trauma have predominantly focused on maltreated populations. This article presents a case study that details the longitudinal outcome of a girl who experienced a motor vehicle accident at 5 years of age. It highlights the clinical relevance of research investigating the neuropsychological impact of single-incident trauma on children. It illustrates difficulties clinicians face in discriminating between the effects of developmental delay, traumatic brain injury, attention-deficit/hyperactivity disorder, trauma, and posttraumatic stress symptoms or posttraumatic stress disorder, especially in children with compensable injuries. The state of the current literature is discussed, and directions for future research are provided.

Background: Emergence delirium (ED) frequently occurs in young children awakening from general anesthesia (GA). To date, research is limited by scales that are unable to discriminate the condition from other forms of agitation., Aim: The primary aim of this study was to determine the core behaviors of ED that discriminate the condition from pain and tantrum in young children and to cluster these behaviors according to the DSM-IV/V core diagnostic criteria and associated behaviors of delirium., Method: Children aged 18 months to 6 years (n=198) were observed upon awakening from GA following surgical or nonsurgical procedures to determine which behaviors categorize ED. Behaviors were recorded via a structured behavioral observation. Clinical opinion was sought to determine whether the child presented ED, pain, or tantrum., Results: A chi-square analysis revealed children with ED were significantly more likely to display activity, nonpurposefulness, eyes averted, stared or closed, no language, and nonresponsivity. These behaviors were not significantly associated with pain or tantrum. A logistic regression showed eyes averted or stared and nonpurposefulness were significant predictors of ED, while no language and activity were not significant predictors of ED., Conclusions: Children with ED are significantly more likely to display nonpurposefulness, eyes averted, stared or closed, and nonresponsivity. These behaviors were not significantly associated with pain or tantrum and are believed to reflect the DSM-IV/V diagnostic criteria for delirium. Associated behaviors of ED identified by this research are irrelevant language, activity, and vocalization., (© 2011 Blackwell Publishing Ltd.)
