SENSORY PROCESSING DURING CHILDHOOD IN PRETERM INFANTS: A SYSTEMATIC REVIEW

Multisensory stimulation for promoting development and preventing morbidity in preterm infants

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of multisensory stimulation compared to any single sensory intervention or standard care for physical and neurological development in preterm infants.

Listening Preference for Child-Directed Speech Versus Time-Reversed Speech in Moderate-Preterm Infants Compared to Full-Term Infants

PURPOSE

The purpose of the present study was to examine whether there is a listening preference for child-directed speech (CDS) over backward speech in moderate-preterm infants (MPIs).

METHOD

Eighteen MPIs of gestational age of 32.0 weeks (range: 32-34.06 weeks), chronological age of 8.09 months, and maturation age of 6.48 months served as the experimental group. The two control groups consisted of a total of 36 infants-20 full-term infants matched for chronological age and 16 full-term infants matched for maturation age. The infants were tested using the central fixation procedure and were presented with 16 trials of CDS and backward speech. A follow-up was conducted 5 years after the initial experiment using a developmental and a five-item parent questionnaire.

RESULTS

MPIs did not demonstrate a preference for CDS over backward speech, whereas both control groups demonstrated a listening preference for CDS over backward speech. MPIs showed a delayed use of first words and word combinations and lower scores on the five-item questionnaire compared to term infants. Twelve MPIs (67%) did not demonstrate a preference for CDS over backward speech. Four of them (33%) were later diagnosed with neurodevelopmental disorders.

CONCLUSIONS

The lack of preference for CDS over backward speech in the MPIs group suggests delayed developmental pattern of speech processing compared to full-term peers. Delays in neurological maturation as well as listening experience in an unregulated environment outside the uterus during a sensitive period of brain development may affect the recognition of phonological and prosodic patterns that support listening preference for speech over backward speech.

Fetal brain growth and infant autistic traits

BACKGROUND

Structural differences exist in the brains of autistic individuals. To date only a few studies have explored the relationship between fetal brain growth and later infant autistic traits, and some have used fetal head circumference (HC) as a proxy for brain development. These findings have been inconsistent. Here we investigate whether fetal subregional brain measurements correlate with autistic traits in toddlers.

METHODS

A total of 219 singleton pregnancies (104 males and 115 females) were recruited at the Rosie Hospital, Cambridge, UK. 2D ultrasound was performed at 12-, 20- and between 26 and 30 weeks of pregnancy, measuring head circumference (HC), ventricular atrium (VA) and transcerebellar diameter (TCD). A total of 179 infants were followed up at 18-20 months of age and completed the quantitative checklist for autism in toddlers (Q-CHAT) to measure autistic traits.

RESULTS

Q-CHAT scores at 18-20 months of age were positively associated with TCD size at 20 weeks and with HC at 28 weeks, in univariate analyses, and in multiple regression models which controlled for sex, maternal age and birth weight.

LIMITATIONS

Due to the nature and location of the study, ascertainment bias could also have contributed to the recruitment of volunteer mothers with a higher than typical range of autistic traits and/or with a significant interest in the neurodevelopment of their children.

CONCLUSION

Prenatal brain growth is associated with toddler autistic traits and this can be ascertained via ultrasound starting at 20 weeks gestation.

Cross-Cultural Adaptation and Reliability of the Toddler Sensory Profile 2 for Brazilian Children Aged 7 to 35 Months

Aim

To organize a cross-cultural adaptation study and analyze the reproducibility and test-retest reliability of a Brazilian version of the Toddler Sensory Profile 2 (TSP2Br) for children aged 7-35 months.

Methods

The English language version of the profile was translated and culturally adapted into Brazilian Portuguese, administered to 168 caregivers of toddlers aged 7-35 months, and then re-administered to a portion of the sample (39 caregivers; 23%) for 7-14 days for test-retest reliability. The internal consistency and test-retest reliability was analyzed using the Cronbach's alpha and kappa coefficient, respectively. As it is a norm-referenced standardized assessment, the cut-off scores used were 1.0 and 2.0 standard deviations above and below the mean for each group of items established as the preliminary cut-off scores for the Brazilian children.

Results

The TSP2Br showed good internal consistency (>0.70) when measured on the total scale; however, when it was analyzed for sensory areas, five to seven areas presented alpha values <.70. By quadrants, alpha was <.70, for all items. The test-retest values fell into the category of near-perfect agreement (.89-.97). The preliminary cut-off points of the Brazilian scores were distinct from those of the Americans.

Conclusions

The TSP2Br showed preliminary reliability and validity in the identification of sensory processing problems in Brazilian children aged 7-35 months; however, it would be necessary to increase the sample size to generalize our findings to the general Brazilian population.

Multisensory stimulation to promote feeding and psychomotor development in preterm infants: A systematic review

BACKGROUND

Sensory stimulation is an intervention that, through peripheral stimuli, can facilitate brain organization, due to neuronal plasticity and cortical reorganization. The objective of this study was to evaluate the evidence about the effects of a multisensory stimulation program, applied on preterm infants, compared to any intervention or standard care, to improve feeding behaviour, and psychomotor development.

METHODS

The data sources included Medline (pubmed, EBSCO), Scopus and Web Of Science. The studies were randomized clinical trials published between 2015 and 2021 that analyzed multisensory stimulation interventions in preterm infants born less than 37 weeks of pregnancy.

RESULTS

Nine articles were identified, involving 545 preterm infants between 25 and 37 weeks of pregnancy. The studies applied different combinations of sensory stimulation. These interventions were related to a better time to achieve full oral feeding and higher consumption of human milk at discharge, better psychomotor development and visual function. All studies scored 6 or higher on the PEDro scale meaning good quality.

CONCLUSION

Multisensory stimulation in preterm infants may improve feeding, psychomotor development, and visual function.

Psychometric Properties of Lower Limb Somatosensory Function and Body Awareness Outcome Measures in Children with Upper Motor Neuron Lesions: A Systematic Review

PURPOSE

A systematic review of the psychometric properties and feasibility of outcome measures assessing lower limb somatosensory function and body awareness in children with upper motor neuron lesion.

METHODS

We followed the COnsensus-based Standards for the selection of health Measurement INstruments guidelines. Two raters independently judged the quality and risk of bias of each study. Data synthesis was performed, and aspects of feasibility were extracted.

RESULTS

Twelve studies investigated eleven somatosensory function measures quantifying four modalities and eight body awareness measures quantifying two modalities. The best evidence synthesis was very low to low for somatosensory function modalities and low for body awareness modalities. Few feasibility aspects were reported (e.g., the percentage or minimum age of participants able to perform the tests).

CONCLUSION

Current evidence on the psychometric characteristics of somatosensory function and body awareness outcome measures are relatively sparse. Further research on psychometric properties and practical application is needed.

Case Report: Motor and Sensory Development of a Case Followed with Suspicion of Neonatal Thiamine Metabolism Dysfunction Syndrome

The aim of this study was to follow early motor and sensory development of the infant with Thiamine Metabolism Dysfunction Syndrome (TMDS). Newborn with 38 weeks gestational age, 2600 kilograms weight admitted to neonatal intensive care unit (NICU) due to respiratory distress, absence of suction reflex, and floppy appearance. Case had respiratory support during 5 weeks. Infant was referred to SANKO University Physiotherapy unit on postterm 12th week due to hypotonia after discharge. Prechtl’s General Movements (GMs) and Hammersmith Infant Neurological Evaluation (HINE) was performed at 3rd and 4th months. Sensory processing parameters were evaluated with the Newborn Sensory Profile-2 (NSP-2). Case had no Fidgety movements (FMs). The HINE score was 37-45 in the 3th and 4th month respectively. Total score in NSP-2 was 33 in the 3rd month (general = 12, auditory = 7, visual = 8, tactile = 2, movement = 2, oral sensory processing = 1). While the case’s Newborn Sensory Profile-2 (NSP-2) total score was in newborn norms, visual, tactile, movement but oral sensory parameters and auditory parameters were in low limits. The low motor performance was associated with low NSP-2 score and showed interaction with motor-sensory development. It is concluded that early physiotherapy program can be effective.

Skin Disease in Children: Effects on Quality of Life, Stigmatization, Bullying, and Suicide Risk in Pediatric Acne, Atopic Dermatitis, and Psoriasis Patients

Acne, atopic dermatitis (AD), and psoriasis are all chronic dermatologic conditions that greatly impact the lives of pediatric patients and their caregivers. The visible nature of these diseases negatively affects the self-image of children early in life as well as their relationships with their families and peers. Physicians recognize the importance of addressing both the physical and mental symptoms of their patients but are currently not equipped with clear guidelines to manage long-term psychosocial comorbidities in pediatric dermatologic patients. A PubMed and Google Scholar search of key words was conducted to explore self-image in pediatric patients with acne, AD, and psoriasis. Chronic skin diseases put pediatric patients at risk for strained family relationships, poor self-image, psychiatric comorbidities, stigmatization, and eventual suicidal behavior. A limitation of this study is a lack of a validated measure of quality of life in the pediatric population that fulfills enough criteria to evaluate long term quality of life in children and adults. Possible management options, including connecting patients with the same diagnosis and allocating resources to parents and teachers to better understand these chronic skin conditions, may provide pediatric patients with the support they need to develop resilience in the face of these challenges.

Prevalence and severity-based classification of sensory processing issues. An exploratory study with neuropsychological implications

Sensory processing issues, mainly known as sensory processing disorder or SPD, are frequent in children with neurodevelopmental disorders and are associated with learning and behavioral difficulties. However, previous studies suggest that these disturbances might also be present in typically developing children, reaching prevalence rates of 10-20%. Nevertheless, published studies have been primary been conducted in non-European countries. Therefore, we aim, as first objective, to explore the frequency of sensory processing difficulties in a random sample of school-age children from Spain to contribute to the study of its prevalence. The Sensory Profile-2 (SP2) assessment tool was administered to 369 participants to study their sensory processing patterns, the absence or presence of sensory processing issues, the affected sensory systems, as well as their socioemotional, attentional, and behavioral impact. Furthermore, as second objective, we have developed a novel strategy to classify SPD by severity ranges using SP2 yielded results; accordingly, the sample was classified as follows: no alteration, mild, moderate, and severe sensory processing alteration. The results show prevalence rates consistent with previous findings: 15.9% of participants met the severe alteration criteria and 10.5%, 11.1% and 62.5% were classified as moderate, mild and no alteration, respectively. Finally, we hypothesize about SPD and underlying neuropsychological processes that might be associated with this condition. Our results highlight the necessity of further research efforts to establish whether high-frequency and severity rates of sensory processing alterations are linked to neuropsychological variables. The provided classification system might be useful to determine such associations.

The Development of a Flexible Bodily Representation: Behavioral Outcomes and Brain Oscillatory Activity During the Rubber Hand Illusion in Preterm and Full-Term School-Age Children

During childhood, the body undergoes rapid changes suggesting the need to constantly update body representation based on the integration of multisensory signals. Sensory experiences in critical periods of early development may have a significant impact on the neurobiological mechanisms underpinning the development of the sense of one’s own body. Specifically, preterm children are at risk for sensory processing difficulties, which may lead to specific vulnerability in binding together sensory information in order to modulate the representation of the bodily self. The present study aims to investigate the malleability of body ownership in preterm (N = 21) and full-term (N = 19) school-age children, as reflected by sensitivity to the Rubber Hand Illusion. The results revealed that multisensory processes underlying the ability to identify a rubber hand as being part of one’s own body are already established in childhood, as indicated by a higher subjective feeling of embodiment over the rubber hand during synchronous visual-tactile stimulation. Notably, the effect of visual-tactile synchrony was related to the suppression of the alpha band oscillations over frontal, central, and parietal scalp regions, possibly indicating a greater activation of somatosensory and associative areas underpinning the illusory body ownership. Moreover, an interaction effect between visual-tactile condition and group emerged, suggesting that preterm children showed a greater suppression of alpha oscillatory activity during the illusion. This result together with lower scores of subjective embodiment over the rubber hand reported by preterm children indicate that preterm birth may affect the development of the flexible representation of the body. These findings provide an essential contribution to better understand the processes of identification and differentiation of the bodily self from the external environment, in both full-term and preterm children, paving the way for a multisensory and embodied approach to the investigation of social and cognitive development.

Application of the Neonatal Behavioral Assessment Scale to Evaluate the Neurobehavior of Preterm Neonates

Background: The neonatal behavioral assessment scale (NBAS) was primarily developed to aid in the assessment of full-term neonates. The aim of this study was to detect if the NBAS was also valuable in the assessment of preterm neonates. Materials and Methods: We assessed 112 infants at a neonatal unit using the NBAS, 4th edition. The inclusion criteria included an oxygen saturation level between 88–95% and a heartrate of 100–205 beats per minute. Infant neurobehavior was assessed using the NBAS. Results: For full-term and preterm neonates, we observed that the NBAS enabled us to assess both groups of infants and gave relevant information pertaining to them. We found a significant correlation between the average week of gestation and response to touch, sensory input, peak of excitement, cost of attention, hand-to-mouth, and quality of alertness. Conclusions: The NBAS is a valuable scale for evaluating the neurobehavior of preterm neonates. The week of gestation at birth affects certain aspects of neurobehavior, such as response to sensory input, putting hand to mouth, peak of excitement, and cost of attention. The NBAS as an individually structured assessment may help in planning for early rehabilitation and intervention for this vulnerable population.

Home-based early stimulation program targeting visual and motor functions for preterm infants with delayed tracking: Feasibility of a Randomized Clinical Trial

AIMS

To verify the feasibility of a home-based early stimulation program targeting visual and motor functions in preterm infants with delayed visual tracking.

METHOD

We applied a randomized controlled trial. We included thirty low-risk preterm infants, from both genders, with delayed visual tracking, gestational between 28-37 weeks, and age at entrance between 1-2 months of corrected age, and absence of visual impairments. Infants were divided into two groups as follows: a) standard care group (SC) that received general orientation about sensory and motor development (16 infants); b) experimental group, that received a four-week home-based early stimulation program targeting visual and motor functions (ESPVM) applied by the caregivers (14 infants). The feasibility outcomes were retention and loss rates, adherence, adverse events, and stress signals. We obtained preliminary data by comparing visual tracking, motor development, and sensory behavior between groups at the end of the intervention.

RESULTS

Retention rate was high, 90 % of the caregivers provided ESPVM at least 22 days, and 70 % provided SC at least 17 days. No adverse events were reported. At the end of intervention, the ESPVM group presented higher frequencies of complete visual tracking for cards 7 (ESPVM = 57.3 %, SC = 6.3 %, p = 0.006) and 8 (ESPVM = 64.3 %, SC = 12.2 %, p = 0.013), and lower scores for total sensory profile (ESPVM: median = 58, range = 46-69; SC: median = 71, range = 54-90; p = 0.016). The groups were similar for motor development.

CONCLUSIONS

The protocol was feasible, and the results encourage a larger randomized controlled trial.

Influence of perinatal complications on the development of a sample of 36-month-old premature infants

OBJECTIVE

The lack of clear results in previous studies for this context makes us consider an exploratory study. The objective of this research is to examine the influence of certain perinatal factors on the development of premature infants over their first 36 months of life.

METHOD

The sample consisted of 59 preterm infants born between 25 and 34 weeks of gestational age in an NICU of a third-level hospital. At 36 months of age, the Bayley-III Infant Development Scale (Spanish adaptation) and a clinical history were collected.

RESULTS

The average scores on the Bayley-III Infant Development Scale were generally within the normal range, but significantly lower than normal for Fine Motor Function, Gross Motor Function, and Expressive Language. These differences remained when considering the degree of prematurity, gender, and perinatal complications. Infants who received mechanical ventilation, oxygen therapy or corticosteroid treatment due to bronchopulmonary dysplasia showed the greatest discrepancies from normal levels.

CONCLUSION

Our results support prior studies that show that a combination of perinatal risk factors constitutes the largest determinant for developmental issues at 36 months of age. This information establishes the need for a priority follow-up in this population beyond 24 months of corrected age.

Sensory processing patterns of young adults with preterm birth history

PURPOSE/AIM

This study aimed to evaluate the sensory processing abilities of young adults with a history of preterm birth and the factors affecting these abilities.

MATERIALS AND METHODS

Thirty-seven young adults with preterm birth history were included. After recording their sociodemographic data, sensory processing functions were evaluated using the Adolescent/Adult Sensory Profile. The participants' data were compared to normative samples.

RESULTS

Mean score was 43.51 ± 8.29 for sensory sensitivity, 44.45 ± 9.19 for sensation avoiding, 33.43 ± 8.45 for low registration, and 47.97 ± 9.91 for sensation seeking. Compared to normative samples, 78% of participants in sensation avoiding quadrant, 62% of participants in sensory sensitivity quadrant, 40% of participants in low registration quadrant and sensation seeking quadrant had atypical scores. When sensory profile scores were analysed according to mode of birth, percentages of typical sensory sensitivity and sensation avoiding were low in both the normal vaginal and caesarean delivery subgroups. When analysed by gestational age at birth, ratios of abnormality in sensation avoiding were similar between individuals with very early, early, and late preterm delivery history. Statistically significant difference was found in low registration and sensation avoiding quadrants according to mode of birth (p < .05). There were no statistically significant sex-based and gestational age at birth differences in any of the four quadrants of the sensory profile in the preterm group (p > .05).

CONCLUSION

These results showed that young adults with preterm birth history have differences in sensory processing compared to the general population and should be evaluated for sensory processing patterns.

Neonatal Multisensory Processing in Preterm and Term Infants Predicts Sensory Reactivity and Internalizing Tendencies in Early Childhood

Multisensory processes include the capacity to combine information from the different senses, often improving stimulus representations and behavior. The extent to which multisensory processes are an innate capacity or instead require experience with environmental stimuli remains debated. We addressed this knowledge gap by studying multisensory processes in prematurely born and full-term infants. We recorded 128-channel event-related potentials (ERPs) from a cohort of 55 full-term and 61 preterm neonates (at an equivalent gestational age) in response to auditory, somatosensory, and combined auditory-somatosensory multisensory stimuli. Data were analyzed within an electrical neuroimaging framework, involving unsupervised topographic clustering of the ERP data. Multisensory processing in full-term infants was characterized by a simple linear summation of responses to auditory and somatosensory stimuli alone, which furthermore shared common ERP topographic features. We refer to the ERP topography observed in full-term infants as "typical infantile processing" (TIP). In stark contrast, preterm infants exhibited non-linear responses and topographies less-often characterized by TIP; there were distinct patterns of ERP topographies to multisensory and summed unisensory conditions. We further observed that the better TIP characterized an infant's ERPs, independently of prematurity, the more typical was the score on the Infant/Toddler Sensory Profile (ITSP) at 12 months of age and the less likely was the child to the show internalizing tendencies at 24 months of age. Collectively, these results highlight striking differences in the brain's responses to multisensory stimuli in children born prematurely; differences that relate to later sensory and internalizing functions.

Brain Damage and Visuospatial Impairments: Exploring Early Structure-Function Associations in Children Born Very Preterm

BACKGROUND

To provide insight into early neurosensory development in children born very preterm, we assessed the association between early structural brain damage and functional visuospatial attention and motion processing from one to two years corrected age.

METHODS

In 112 children born at less than 32 weeks gestational age, we assessed brain damage and growth with a standardized scoring system on magnetic resonance imaging (MRI; 1.5 Tesla) scans performed at 29 to 35 weeks gestational age. Of the children with an MRI scan, 82 participated in an eye tracking-based assessment of visuospatial attention and motion processing (Tobii T60XL) at one year corrected age and 59 at two years corrected age.

RESULTS

MRI scoring showed good intra- and inter-rater reproducibility. At one year, 10% children had delayed attentional reaction times and 23% had delayed motion reaction times. Moderate to severe brain damage significantly correlated with slower visuospatial reaction times. At two years, despite attention and motion reaction times becoming significantly faster, 20% had delayed attentional reaction times and 35% had delayed motion reaction times, but no correlations with MRI scores were found. The presence of structural brain damage was associated with abnormal functional performance over age.

CONCLUSIONS

The present study indicates an association between moderate to severe brain damage and visuospatial attention and motion processing dysfunction at one year corrected age. This provides a new perspective on comprehensive MRI scoring and quantitative functional visuospatial assessments and their applicability in children born very preterm in their first years of life.

Neuromotor and sensory development in preterm infants: prospective study

Aim

To investigate the relationship between motor and sensory development in the first 4 months of life in preterm infants born at 32 gestational weeks and below.

Material and Methods

The study consisted of 56 high-risk infants with a corrected age of 1 month who were born at 32 gestational weeks and stayed in the neonatal intensive care unit for at least 15 days. Neuro Sensory Motor Developmental Assessment and Infant Sensory Profile-2 were used for evaluation. These assessments were applied to preterm infants at the 1^st and 4^th months. The results of assessments were analyzed using the Wilcoxon test. The relationship between the results of motor and sensory assessments was analyzed using Spearman's correlation test.

Results

The mean gestational age of the infants was 29.58±2.09 weeks, their birth weights were 1233.87±251.22 grams, and their duration of stay in the neonatal intensive care unit was 26.48±9.58 days. There was a statistically significant difference between the Neuro Sensory Motor Developmental Assessment and Infant Sensory Profile-2 scores between the 1^st and 4^th months (p<0.05). It was found that there was a risk in terms of sensory development in 86-91% of the preterm infants at the 1^st month and in 69-85% at the 4^th month. There was moderate-strong degree of significant relationship between motor and sensory development.

Conclusion

Considering the findings of our study, preterm infants are at risk for motor and sensory development. There is, therefore, a need for future research to investigate the effect of early sensory-based intervention approaches on preterm infants.

Systematic review of sensory processing in preterm children reveals abnormal sensory modulation, somatosensory processing and sensory-based motor processing

AIM

Preterm birth poses concerns in daily functioning and behaviour in childhood, possibly connected to sensory processing disorder. This review aimed to systematically identify assessments, incidence and nature of sensory processing disorder in preterm-born infants and children.

METHODS

We searched literature through CINAHL-EBSCOhost, Cochrane, Ovid/PsychINFO, PubMed/Medline, Scopus and Google Scholar, published until November 2018. We included electronically available, peer-reviewed studies of preterm-born children that applied standardised sensory processing assessments. We excluded studies of preterm-born children with major neurodevelopmental impairments.

RESULTS

We identified 27 studies of premature children, aged from birth to 9 years 7 months. The assessments represented three versions of Sensory Profile questionnaires and three clinical tests, Test of Sensory Functions in Infants, the Miller Assessment for Preschoolers, and the Sensory Integration and Praxis Test. The studies revealed wide variation of atypical sensory processing: 28%-87% in sensory modulation, 9%-70% in somatosensory processing and 20%-70% in sensory-based motor processing.

CONCLUSION

Preterm-born children exhibited elevated risk for sensory processing disorder from infancy into school age. Routine screening of sensory processing, intervention intervals and parental consultations should be considered in ameliorating sensory processing and neurocognitive development. Moreover, a larger body of intervention studies is needed.

Utilization of a Novel Pathway in a Tertiary Pediatric Hospital to Meet the Sensory Needs of Acutely Ill Pediatric Patients

Objective: To identify pediatric patients with sensory sensitivities during a hospital visit, and to implement a clinical pathway that can meet their sensory needs. The goal is to remove barriers to care delivery that is related to the sensory need for pediatric patients who present with an acute medical illness. Methods: The clinical pathway (identified as 'Sensory Pathway') was developed as a joint effort between key stakeholders within the community and medical providers. The pathway was conducted in a tertiary pediatric hospital from September 2016-April 2019. The main components of this pathway included- 1. Staff training; 2. Provision of sensory toolkits and story board; 3. Early collaboration with allied professionals; and 4. Early and continuous parental involvement. The Sensory Pathway was implemented first in the emergency department, followed by inpatient units. Patients triggered the pathway through caregiver or staff identification. Demographic of patients who triggered the pathway was extracted. A detailed qualitative analysis of any parents' feedback received was performed. Results: A cohort of patients with sensory needs was identified amongst pediatric patients who presented to the hospital with an acute illness. The most common comorbidity associated with sensory sensitivity/need was Autism Spectrum Disorder (48%), followed by cerebral palsy (22.8%) and Attention-Deficit/Hyperactivity Disorder (16%). 1337 patients (51.8%) had a single comorbidity while 45.9% patients had more than one comorbidity. Only 1.3% patients had a known diagnosis of sensory processing disorder. The pathway was triggered in 2,580 patient visits with 1643 patients and 937 repeat visits. The vast majority of patients who triggered the pathway had a medical presenting complaint (vs. behavioral). The following themes emerged from the parents' feedback: 1. Additional help received specific to the child's sensory needs; 2. Feeling of comfort; and 3. Improved overall experience. Conclusion: The Sensory Pathway identified a unique profile of pediatric patients who have sensory needs during their hospital stay. The pathway was successfully implemented for children with sensory need in our hospital across a wide range of demographic and with varied medical illness.

Neuroinflammation in preterm babies and autism spectrum disorders

Genetic anomalies have a role in autism spectrum disorders (ASD). Each genetic factor is responsible for a small fraction of cases. Environment factors, like preterm delivery, have an important role in ASD. Preterm infants have a 10-fold higher risk of developing ASD. Preterm birth is often associated with maternal/fetal inflammation, leading to a fetal/neonatal inflammatory syndrome. There are demonstrated experimental links between fetal inflammation and the later development of behavioral symptoms consistent with ASD. Preterm infants have deficits in connectivity. Most ASD genes encode synaptic proteins, suggesting that ASD are connectivity pathologies. Microglia are essential for normal synaptogenesis. Microglia are diverted from homeostatic functions towards inflammatory phenotypes during perinatal inflammation, impairing synaptogenesis. Preterm infants with ASD have a different phenotype from term born peers. Our original hypothesis is that exposure to inflammation in preterm infants, combined with at risk genetic background, deregulates brain development leading to ASD.

Balance performance of children and adolescents with sensorineural hearing loss: Repercussions of hearing loss degrees and etiological factors

INTRODUCTION

Some studies have demonstrated a parallelism between the extent of hearing loss and the frequency of vestibular dysfunction in children with sensorineural hearing loss (SNHL). Despite this, little is known about the repercussion of degrees of hearing loss and etiological factors on the balance performance in this children.

OBJECTIVE

Compare the balance performance between normal hearing (NH) children and those with SNHL, considering the sex and age range of the sample, and analyze balance performance according to the degrees of hearing loss and etiological factors in the latter group.

METHODS

Cross-sectional study that assessed 96 children (48 NH and 48 with SNHL), aged between 7 and 18 years old. The balance performance was assessed by the Brazilian version of the Pediatric Balance Scale, validated for Brazilian child population and the Mann-Whitney test used for statistical analysis.

RESULTS

The group with SNHL showed lower average balance performance compared to NH (p = 0.000). This was also observed when the children were grouped by sex: female and male (p = 0.001). The same difference occurred when the children were stratified by age group: 7-14 years old (p = 0.000). There were no differences between the balance performance of the groups according to the degrees of hearing loss (p = 0.236) and the children with prematurity or post-natal meningitis as an etiological factor demonstrated the worst balance performance.

CONCLUSION

The children with SNHL showed worse balance performance compared to NH of the same sex and age range between seven to fourteen years. There were no differences between balance performance and hearing loss degrees, and those children with prematurity or post-natal meningitis as an etiological factor demonstrated the worst balance performances.
