The clinical features of achondroplasia can cause acute self-limited pain that can evolve into chronic pain. Pain causes a low quality of life, in terms of physical, emotional, social, and school functioning in both adult and children with achondroplasia. We conducted a systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement to describe prevalence, assessment tools, causes and management strategies of pain in this rare disease. We found that shoulder and knee pain is typically referred during infancy, while knee pain is generally referred around 5–6 years of age. The prevalence of general pain in adolescence can be as high as 90%. Chronic pain in the achondroplasia population increases with age, with up to 70% of adults reporting general pain and back pain. Recognizing the multiple determinants of acute and chronic pain in patients with achondroplasia may enable physicians to better understand and manage this burden, particularly with the advent of new drugs that may modify some of the striking features of achondroplasia.

Late-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelae and iron deficiency. The aim of the study is to assess the positive effect of iron supplementation on psychomotor development in healthy LPT. We designed a randomized placebo-controlled double-blind trial dividing the newborns into two groups. Every patient was assessed using the Griffiths Mental Development Scales (GMDS)-II edition at 12-month post-conceptional age. The study was performed at the Neonatology Unit of our Hospital, in Italy. Sixty-six healthy LPT infants born between -340/7 and -366/7 weeks of gestational age were enrolled in the study. One group received martial prophylaxis from the third week of life to 6 months of post-conceptional age (2 mg/kg/day of iron pidolate), the other received placebo. Fifty-two of the enrolled infants were assessed using the GMDS at 12-month of post-conceptional age. Statistical analysis of the mean scores of the Griffiths subscales was performed. There was a difference in the mean developmental quotient (DQ) (p < 0.01) between the two groups: iron group mean DQ 121.45 +/- 10.53 vs placebo group mean DQ 113.25 +/- 9.70. Moreover, mean scores of the Griffiths subscales A, B, and D showed significant differences between the two groups (scale A p < 0.05, scale B p < 0.02, scale D p < 0.01, respectively).Conclusions: We recommend that all LPT neonates receive iron supplementation during the first 6 months of life in order to improve their 1-year neurodevelopmental quotient.

Our aim was to develop a new module for assessing the floppy infant, to describe the application of the module in a cohort of low-risk newborns and piloting the module in a cohort of floppy infants. The module was applied to a cohort of 143 low-risk newborns and piloted in in a cohort of 24 floppy infants. The new add-on module includes a neurological section and provides a section for recording information obtained by physical examination and antenatal history. For each item, column 1 reports abnormal findings, column 3 normal findings, and column 2 intermediate signs to be followed. Consistent with previous studies, in low-risk infants, none had definitely abnormal or mildly abnormal signs, with the exception of tendon reflexes that were not easily elicitable in 17.14% of term-born infants. Conclusion: Our study suggest that the module can be easily used in a clinical setting as an add-on to the regular neonatal neurological examination in newborns identified as hypotonic on routine examination. Larger cohorts are needed to establish the accuracy of the prognostic value of the module in the differential diagnosis of floppy infant.What is Known:• Hypotonia is one of the key signs in newborns with neuromuscular disorders and can be associated with a wide range of other conditions (central nervous system involvement, genetic and metabolic diseases).• Weakness or/and contractures can identify infants with a neuromuscular disorder and help in the differential diagnosis of floppy infants.What is New:• To date, this is the first attempt to develop and apply a specific neurological module for the assessment of the floppy infant.• The module can be used in a routine clinical setting as an add-on to the regular neurological examination and has potential to differentiate the floppy infants from the low-risk infants.

Background and Objectives: Preterm infants are at higher risk of neurodevelopmental impairment both at preschool and school ages, even in the absence of major neurological deficits. The early identification of children at risk is essential for early intervention with rehabilitation to optimize potential outcomes during school years. The aim of our study is to assess cognitive outcomes at preschool age in a cohort of low-risk very preterm infants, previously studied at 12 and 24 months using the Griffiths scales. Materials and Methods: Sixty-six low-risk very preterm infants born at a gestational age of <32 weeks were assessed at 12 and 24 months corrected age using the Griffiths Mental Development Scales (second edition) and at preschool age with the Wechsler Preschool and Primary Scales of Intelligence (third edition) (WPPSI-III). Results: At 12 and 24 months and at preschool age, low-risk very preterm infants showed scores within normal ranges with similar scores in males and females. A statistically significant correlation was observed in the general developmental quotient between 12 and 24 months; a further significant correlation was observed between the early cognitive assessments and those performed at preschool age, with a better correlation using the assessments at 24 months. Conclusion: The present study showed a favourable trajectory of cognitive development in low-risk very preterm infants, from 12 months to preschool age.

Aim: We explored the ability of the Hammersmith Infant Neurological Examination (HINE) to identify cognitive performance delay at 2 years in a large cohort of infants born at term. Method: We conducted a retrospective study of infants born at term at risk of neurodevelopmental impairments assessed using the HINE between 3 and 12 months post-term age and compared them with a cohort of typically developing infants born at term. All infants performed a neurodevelopmental assessment at 2 years of age using the Mental Development Index (MDI) of the Bayley Scales of Infant Development, Second Edition; the presence of cerebral palsy (CP) was also reported. The infants were classified as being cognitively normal/mildly delayed or significantly delayed (MDI < 70). The predictive validity of HINE scores for significantly delayed cognitive performance, in infants with and without CP, was calculated using specific cut-off scores according to age at assessment. Results: A total of 446 at-risk and 235 typically developing infants (345 males, 336 females; mean [SD] gestational age 38.7 weeks [1.4], range 25–36 weeks) were included. Of the at-risk infants, 408 did not have CP at 2 years; 243 had a normal/mild delayed MDI and 165 had an MDI less than 70. Of the at-risk infants, 38 developed CP. HINE scores showed a good sensitivity and specificity, mainly after 3 months, for identifying significantly delayed cognitive performance in infants without CP. In those with CP, the score was associated with their cognitive performance. The comparison group had the highest HINE scores. Interpretation: The HINE provides evidence about the risk of delayed cognitive performance at age 2 years in infants born at term with and without CP.

In the last years, new evidence has increased the attention on sex differences in the development of children with cerebral palsy (CP). Males seem to present with a higher risk for severe motor impairment and in the response to chirurgical and rehabilitative interventions. The published data confirmed a higher incidence of CP in males than in females. The aim of this literature review was to evaluate the impact of the sex on the most important areas that characterized CP: motor function, comorbidities (pain, cognitive impairment, communications skills, epilepsy, sleep, and behavior), and the different kind of interventions.

Aim: To describe the profile of global and single items of the Hammersmith Infant Neurological Examination (HINE) in a population of low-risk infants born very preterm during the first year of life. Method: The HINE was performed at 3, 6, 9, and 12 months’ corrected age in a population of low-risk infants born preterm with a gestational age of fewer than 32 weeks and with normal or minimal changes on neuroimaging. Results: A total of 174 infants born preterm (96 males, 78 females; mean gestational age = 27 weeks [SD = 1.8], range 23–31 weeks) fulfilled the inclusion criteria. The 10th centile cut-off score with median and range was reported for the HINE global and subsection scores. A progressive increase in global HINE scores was observed. Most of the single items, especially those related to tone, posture, and reflexes, showed progressive maturation. Interpretation: Our results, which provide longitudinal data for single-item and global scores in a population of low-risk infants born very preterm, can be used as a reference in both clinical and research settings to monitor early neurological signs in these infants. These data could be used as normative data when examining low-risk infants born preterm.

Introduction: Ureaplasma (U.) and Mycoplasma (M.) species have been related to pregnancy complications (including preterm birth) and worse neonatal outcomes. The aim of our work is to evaluate neurodevelopmental outcomes in preterm infants born to mothers with Ureaplasma/Mycoplasma colonization during pregnancy. Methods: Preterm infants with gestational age (GA) of ≤ 30 weeks were included in a retrospective follow-up study. To evaluate the effects of maternal vaginal colonization, we divided preterm infants into two groups: exposed and unexposed infants. All infants were assessed at 24 ± 3 months of age using Griffith's Mental Developmental Scales (GMDS). Results: Among 254 preterm infants, only 32 infants (12.6%) were exposed to U. /M. colonization during pregnancy. Exposed infants and unexposed ones had a similar Griffith's Developmental Quotient (106 ± 27.2 vs. 108.9 ± 19.5, respectively), without significant differences (p = 0.46). However, exposed infants had a significantly poorer outcome than their unexposed peers in terms of locomotor abilities (100.7 ± 28.3 exposed vs. 111.5 ± 26.1 unexposed, p = 0.03). Conclusion: For visual and hearing impairment, exposed and unexposed infants had similar incidences of cognitive and motor impairment. However, exposed infants had significantly lower locomotor scores than unexposed peers. Keywords: cognitive; motor outcomes; motor performance; neonate; neurodevelopment; newborn; pregnant; prematurity—risk assessment and prevention.

Importance: Cerebral palsy (CP) is the most common childhood physical disability. Early intervention for children younger than 2 years with or at risk of CP is critical. Now that an evidence-based guideline for early accurate diagnosis of CP exists, there is a need to summarize effective, CP-specific early intervention and conduct new trials that harness plasticity to improve function and increase participation. Our recommendations apply primarily to children at high risk of CP or with a diagnosis of CP, aged 0 to 2 years. Objective: To systematically review the best available evidence about CP-specific early interventions across 9 domains promoting motor function, cognitive skills, communication, eating and drinking, vision, sleep, managing muscle tone, musculoskeletal health, and parental support. Evidence Review: The literature was systematically searched for the best available evidence for intervention for children aged 0 to 2 years at high risk of or with CP. Databases included CINAHL, Cochrane, Embase, MEDLINE, PsycInfo, and Scopus. Systematic reviews and randomized clinical trials (RCTs) were appraised by A Measurement Tool to Assess Systematic Reviews (AMSTAR) or Cochrane Risk of Bias tools. Recommendations were formed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework and reported according to the Appraisal of Guidelines, Research, and Evaluation (AGREE) II instrument. Findings: Sixteen systematic reviews and 27 RCTs met inclusion criteria. Quality varied. Three best-practice principles were supported for the 9 domains: (1) immediate referral for intervention after a diagnosis of high risk of CP, (2) building parental capacity for attachment, and (3) parental goal-setting at the commencement of intervention. Twenty-eight recommendations (24 for and 4 against) specific to the 9 domains are supported with key evidence: motor function (4 recommendations), cognitive skills (2), communication (7), eating and drinking (

Aim: Extra-uterine Growth Restriction (EUGR) is common among preterm infants. Two types of EUGR definitions are still now available: cross-sectional definitions and longitudinal ones. In a cohort of very preterm infants, we aimed to evaluate which definition could better predict neurodevelopmental outcomes at 2 years of corrected age. We used Italian Neonatal Study Charts (INeS) growth charts and INTERGROWTH-21st (IG-21) standard charts and compared results. Method: We restrospectively collected data from clinical charts of 324 preterm newborns with a gestational age ≤30 weeks born from 2012 to 2017. Then we compared forty-eight definitions (24 cross-sectional and 24 longitudinal) of EUGR, in term of neurodevelopmental outcomes at 2 years of corrected age. Results: We included in the study 254 preterm infants, whose clinical information met the enrolment criteria. Nineteen out of 48 definitions of EUGR were significantly predictive both for Griffith's Development Quotient (GDQ) and Neurodevelopment Impairment (NDI). Among these, longitudinal definitions appeared to have a higher negative predictive value for NDI than cross-sectional ones. Furthermore, infants with EUGR appeared to have a lower cognitive score than their peers without EUGR. Interpretation: A loss of Zs > 1 SDS in weight and head circumference, calculated from when physiological weight loss is over and identified as soon as possible rather than at discharge, better predicts neurodevelopmental outcomes of preterm infants.

The emergency created by Coronavirus disease 2019 (COVID-19) has inevitably changed human normal social and relational habits. The use of personal protective equipment, like surgical masks, by healthcare workers has been recommended to prevent human-to-human transmission of the novel coronavirus infection. However, the use of these masks could cause slight to considerable and reproducible changes in the infant's attitude towards the operator and health taker during routine clinical assessments. We reported a brief report on the impact of to the use of the surgical masks on the affective behaviour in 40 infants of age 2–9 months (study group) by using a scale to assess pain and distress among pediatric patients, the Face, Legs, Activity Cry and Consolability Scale (FLACC), and in 40 infants with the same ages and characteristics assessed before the COVID-19 pandemia onset (control group). Thirty-seven of the 40 infants in the study group had some signs of discomfort and appeared irritable and less prone to be engaged by the examiner with a different pattern of responses related to age with better responses for younger infants. These infants reported higher significant scores (p < 0.001) in the FLACC scale than those assessed before the COVID-19 onset. Infants appear to react negatively to the use of the surgical mask by the health operator. A different way to assess paediatric patients in early infancy with longitudinal studies should be proposed.

Background: JAM3 gene, located on human chromosome 11q25, encodes a member of the junctional adhesion molecule (JAM) family. Mutations of this gene are associated with hemorrhagic destruction of the brain, subependymal calcification, and congenital cataracts (HDBSCC). Case report: Herein, we present a newborn male with a prenatal suspicion of bilateral cataracts but without fetal ultrasound findings of cortical malformations. He was postnatally diagnosed with a clinical picture of HDBSCC and Early-onset Developmental and Epileptic Encephalopathy (DEE), associated to a homozygous variant of JAM3 gene. Conclusion: Identification of this variant in affected individuals has implications for perinatal and postnatal management and genetic counseling. To the best of our knowledge, this is the first case reported of a child with a JAM3 variant in Italy, from a different ethnic background than the other reported children until now (Saudi Arabian, Turkish, Afghani, and Moroccan origin). JAM3 screening could be requested in prenatal diagnosis of fetal congenital cataracts and included in Next-Generation DNA Sequencing panels.

We describe the case of a male newborn presenting with a prenatal diagnosis of persistent hyperextension of the fetal neck and severe hypotonia and respiratory insufficiency at birth. Facial weakness, increased serum creatine kinase levels, and abnormal feeding, together with other signs, such as severe contractures, also classically associated with congenital myopathies prompted to perform a muscle biopsy showing internal rods suggestive of a possible nemaline myopathy. These findings suggest that a careful neurological examination should be performed in infants with persistent hyperextension of the fetal neck to exclude weakness and a possible underlying muscle disorder.

Background and Objectives: Sleep disorders are common in children with Autism Spectrum Disorder (ASD). The aims of this study were to describe the incidence and characteristics of sleep disorders using a questionnaire completed by the caregiver in a sample of preschool-aged children with ASD and to identify possible differences in a control group of peers. Materials and Methods: Sleep disorders were investigated with the Sleep Disturbance Scale for Children (SDSC) in a population of pre-school-aged (3–5 years) ASD children and in a control group. The Autism Diagnostic Observation Schedule—second ed. (ADOS-2) was further used to assess autism symptom severity. A total of 84 children (69 males; mean age 3.9 ± 0.8 years) with a diagnosis of ASD and 84 healthy controls (65 males; mean age of 3.7 ± 0.8 years) that were matched for age and sex were enrolled. Results: ASD children reported significantly higher (pathological) scores than the control group on the SDSC total scores and in some of the factor scores, such as Difficulty in Initiating and Maintaining Sleep (DIMS), disorders of excessive somnolence (DOES), and sleep hyperhidrosis. A total of 18% of ASD children had a pathological SDSC total T-score, and 46% had an abnormal score on at least one sleep factor; DIMS, parasomnias, and DOES showed the highest rates among the sleep factors. Younger children (3 years) reported higher scores in DIMS and sleep hyperhidrosis than older ones (4 and 5 years). No specific correlation was found between ADOS-2 and SDSC scores. Conclusions: Pre-school children with ASD showed a high incidence of sleep disorders with different distributions of specific sleep factors according to their age. We suggest a screening assessment of sleep disorders using the SDSC in these children with a more in-depth evaluation for those reporting pathological scores on the questionnaire.

Objectives: The aim of the present study is to assess the psychometric properties of the Sleep Disturbance Scale for Children (SDSC) in an Italian population of infants and toddlers. Methods: The SDSC was distributed to the primary caregivers of infants aged 6–36 months recruited via nurseries in the urban area of Rome. Reliability analysis for evaluating internal consistency and item–total correlation coefficients, and factor analysis were performed. Results: During a 12-months study period, a total of 193 healthy infants (aged 6–36 months) were evaluated using a 22-item version of the SDSC for Italian infants and toddlers. Three of the 22 original items displayed a low item–total correlation (<30) and a low frequency and were eventually removed, resulting in a 19 items questionnaire. Six factors were derived from the factor analysis using the principal component method of extraction and rotated with the varimax method: Difficulty in initiating sleep, Difficulty in maintaining sleep, Sleep breathing disorders, Parasomnias, Disorders of excessive somnolence and Sleep hyperhidrosis. The SDSC adapted for infants and toddlers showed a good level of internal consistency (Cronbach's alpha: 0.83). Conclusions: The statistical analysis, the internal consistency and the factor analysis encourage the use of SDSC as an evaluation tool even at this age. The six factors extracted represent the most common areas of sleep disorders at this age and could therefore help clinicians to detect the areas that need a deeper investigation.

Tetrabenazine has been studied with a variety of hyperkinetic movement disorders, but there is limited and empirical literature on the potential efficacy of tetrabenazine in children with dyskinetic cerebral palsy (DCP). The purpose of this study was to evaluate the efficacy of tetrabenazine in a sample of children with DCP using the Movement Disorders—Childhood Rating Scale 4–18 Revised (MD-CRS 4–18 R). The study is a multicenter retrospective longitudinal study in which the participants were selected from the databases of each Center involved, according to detailed inclusion criteria. The study was performed on 23 children and adolescents (19 male and 4 females; mean age 8.28 years, SD 3.59) with DCP having been evaluated before starting the treatment (baseline), after 6 and 12 months of treatment and in a sub-cohort after >2 years follow-up. A linear mixed model was used to evaluate the effects of the different timings on each MD-CRS 4–18 R Index (Index I, Index II, and Global Index) adding age and type of movement disorder as random effect. A significant clinical improvement related to a reduction of MD-CRS 4-18 R Indexes was detected between the baseline and after 6 and 12 months of treatment. Findings support the efficacy of tetrabenazine in children with DCP through a standardized outcome measure (MD-CRS 4–18 R) and confirm the use of this scale as a suitable tool to detect changes in further randomized clinical trials.

The partial trisomy 13q encompasses an extensive variability of phenotypic and radiolog-ical findings including leukoencephalopathy and brain malformations such as holoprosencephaly, callosal dysgenesis, hippocampal hypoplasia, olfactory hypoplasia, and vermian hypoplasia. We report for the first time a case of a 23-year-old patient affected by de novo partial 13q22.1q34 trisomy (41.7 Mb, 72,365,975-114,077,122x3) presenting with hemiparesis related to both ischemic and haem-orrhagic cerebral lesions compatible with cerebral vasculitis due to a possible combination of genetic and immunological interaction.

Background and Objectives: Late preterm (LP) infants (born between 34 and 36 weeks of gestational age) are considered at higher risk of neonatal morbidities, mortality, and neurological impairments than full-term born infants (FT). The aim of this study was to provide a critical review of the literature outlining the different aspects of neurological function reported both in the neonatal period and in the follow up of late preterm infants. Materials and Methods: A comprehensive search of the MEDLINE, Embase, PsycINFO, and CINAHL electronic databases was made, using the following search terms: ‘Late preterm infants’, ‘Near term infants’, ‘neurological assessment’, ‘neurological outcome’, ‘neuromotor outcome’, cerebral palsy’, ‘CP’, ‘motor impairment’, including all the studies reporting clinical neurological assessment of LP (including both neonatal period and subsequent ages). Results: A total of 35 articles, comprising 301,495 children, were included as fulfilling the inclusion criteria: ten reported neonatal neurological findings, seven reported data about the first two years after birth, eighteen reported data about incidence of CP and motor disorder during the infancy. Results showed a more immature neurological profile, explored with structured neurological assessments, in LP infants compared with FT infants. The LP population also had a higher risk of developing cerebral palsy, motor delay, and coordination disorder. Conclusion: LP had a higher risk of neurological impairments than FT infants, due to a brain immaturity and an increased vulnerability to injury, as the last weeks of gestational age are crucial for the development of the brain.

Aim: We explored the ability of the Hammersmith Infant Neurological Examination (HINE) to identify typical and delayed cognitive performance in a large population of infants born preterm, both with and without cerebral palsy (CP). Method: We conducted a retrospective study of infants born preterm who had repeated HINEs between 3 and 12 months corrected age. At 2 years, cognition was assessed using the Mental Development Index (MDI; from the Bayley Scales of Infant Development, Second Edition) and the presence and severity of CP was determined. All children were classified as cognitively typical/mildly delayed or significantly delayed (MDI <70) and CP. The predictive validity of HINE scores for significantly delayed cognitive performance, in children with and without CP, was calculated using specific cut-off scores according to age at assessment. Results: Of 1229 eligible infants (gestational age 25–36wks, mean [SD] 34.9 [2.3]; 646 males, 583 females), 1108 did not develop CP, 891 had an MDI that was typical/mildly delayed, and 217 had an MDI less than 70. Of the 121 infants who developed CP, the MDI was typical in 28, mildly delayed in 27, and less than 70 in 66. HINE scores showed a good sensitivity and specificity, especially after 3 months, for detecting significantly delayed cognitive performance in infants without CP. In those who developed CP, the score was associated with their cognitive level. Interpretation: The HINE provides information about the risk of delayed cognitive performance in infants born preterm with and without CP.

Costello syndrome (CS), a rare syndrome with multisystemic involvement inherited as a dominant trait, is characterized by developmental delay, coarse facial appearance, cardiac defects including hypertrophic cardiomyopathy, skin abnormalities, brain complications, and a predisposition to certain malignancies. The musculoskeletal system is particularly affected in CS, with peculiar orthopedic anomalies that impact posture and gait. Dystonia has been recently documented to contribute to abnormal postures and musculoskeletal anomalies characterizing CS, suggesting the possible use of pharmacological treatments to treat these complications. We report the case of a child affected by CS displaying a particularly severe musculoskeletal involvement with dystonic posture especially in the arms and legs. The Movement Disorder‐Childhood Rating Scale (MD‐CRS) and a gait analysis were used to assess clinical patterns of hyperkinetic movement disorder and dystonia. The child was further treated with trihexyphenidyl for six months with a final dosage of 14 mg. MD‐CRS and gait analysis assessments provided evidence for a significant improvement of posture and the related musculoskeletal problems with no side effects. Our preliminary study report provides first evidence that pharmacological anti‐dystonia treatment significantly improves movement and posture disorders in patients with CS. Further studies enrolling larger cohorts of patients should be performed to validate these preliminary observations.

Background: Retinopathy of prematurity (ROP) is often associated with visual impairment and multiple developmental disabilities. Aims: As most of the previous studies include infants with brain lesions, that can determine visual impairment per se, a cohort of low neurological risk preterm infants without ROP and with various degree of severity of ROP was assessed in order to establish visual and neurodevelopmental outcome. Study design: Preterm infants born at <31 weeks gestation, without major brain lesions, underwent visual function assessment at 1 year corrected age and neurodevelopmental assessment at 2 years corrected age. Subjects: One hundred and five infants were included in the study: 42 infants did not develop ROP, 7 reached stage 1 in zone 2 ROP, 37 reached prethreshold (untreated) type 2 ROP. The remaining 19 infants were classified as type 1 ROP. Outcome measures: Visual function (including fixing, tracking, visual acuity, visual field, attention at distance and nystagmus) were assessed at 12 months corrected age and Griffiths Scales at 2 years corrected age. Results: The severity of ROP was strongly correlated (p < 0.001) with both visual function at 1 year and neurodevelopment at 2 years. Similarly, the presence of nystagmus was also strongly correlated with visual and neurodevelopmental sequelae. Conclusions: Infants with no or milder retinopathy showed normal visual function at 1 year and neurodevelopment at 2 years. Infants who underwent treatment more frequently showed abnormal results on several aspects of visual function. Presence of nystagmus appeared to increase the risk for abnormal visual function and neurodevelopmental outcome.

Objectives: (i) to assess the presence of sleep disorders in a population of very preterm children (ie, with a gestational age [GA] ≤ 31 weeks) of preschool age with no history of neurological disabilities using a questionnaire standardized for this age group and (ii) to identify possible differences in a control group of term-born children. Methods: A total of 146 low-risk preterm children (mean gestational age 28 weeks; range: 25–30), were assessed at a preschool age (mean age 3.8 years; range 3–6 years) using the sleep disturbance scale for children (SDSC) to assess sleep problems. As controls, 146 typically developing children matched for age and gender were also evaluated using the SDSC. Results: An abnormal total sleep score (>70) was found in 7% of preterm children, while 21% had an abnormal score on at least one SDSC factor. No significant differences were reported according to the age of assessment or gestational age. The preterm group reported higher significant median scores on SDSC total, sleep-disordered breathing, sleep hyperhidrosis and difficulty in initiating and maintaining sleep factors. Conclusions: Low-risk very preterm children showed only a slightly higher incidence of sleep disorders than term-born peers at preschool age, with higher scores in specific sleep factors. These data could be useful to clinicians for screening those preterm children at risk for sleep disorders who need a more detailed assessment for a conclusive diagnosis and treatment.

Background High-risk infant follow-up programs provide early identification and referral for treatment of neurodevelopmental delays and impairments. In these programs, a standardized neurological examination is a critical component of evaluation for clinical and research purposes. Methods To address primary challenges of provider educational diversity and standardized documentation, we designed an approach to training and implementation of the Hammersmith Infant Neurological Examination with precourse materials, a workshop model, and adaptation of the electronic medical record. Conclusions Provider completion and documentation of a neurological examination were evaluated before and after Hammersmith Infant Neurological Examination training. Standardized training and implementation of the Hammersmith Infant Neurological Examination in a large high-risk infant follow-up is feasible and effective and allows for quantitative evaluation of neurological findings and developmental trajectories.

BACKGROUND: We have previously developed and described a battery of 9 items suitable for assessing different clinical aspects of visual function in newborn infants. AIM OF THE STUDY: Application of the test battery to a cohort of low risk term-born infants at 48 and 72 h after birth 1) to define the normative distribution of results for each item and 2) to document any effect of postnatal age. STUDY DESIGN AND SUBJECTS: 124 term-born low risk infants were assessed at 48 h; fifty of them were re-assessed 24 h later at 72 h. RESULTS: The visual test battery was successfully completed in 110 of the 124 infants assessed at 48 h and in all the 50 infants assessed at 72 h after birth. For 3 of the 9 items (fixation on a black/white target of concentric circles, on a coloured (red/yellow) face and horizontal tracking), the findings were very similar at both ages. For the remaining 6 items the range of findings was wider. There was a statistical difference in the responses obtained at 48 and 72 h for vertical and arc tracking (p<0.05) and the ability to discriminate stripes and attention at distance (p<0.001). CONCLUSION: Our results provide information on the visual abilities in a low risk population of term-born infants and the distribution of frequency of their visual responses to our battery of visual tests. These findings may be used as reference data when using our visual test battery in both clinical and research settings.
