[PMID: 38789787 DOI: 10.1038/s41433-024-03116-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 04/08/2024] [Accepted: 04/25/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Ocular trauma is a significant cause of blindness and is often missed in polytrauma. No contemporary studies report eye injuries in the setting of severe trauma in the UK. We investigated ocular injury epidemiology and trends among patients suffering major trauma in England and Wales from 2004 to 2021. METHODS We conducted a retrospective study utilising the Trauma Audit and Research Network (TARN) registry. Major trauma cases with concomitant eye injuries were included. Major trauma was defined as Injury Severity Score >15. Ocular injuries included globe, cranial nerve II, III, IV, and VI, and tear duct injuries. Orbital fractures and adnexal and lid injuries were not included. Demographics, injury profiles, and outcomes were extracted. We report descriptive statistics and 3-yearly trends. RESULTS Of 287 267 major trauma cases, 2368 (0.82%) had ocular injuries: prevalence decreased from 1.87% to 0.66% over the 2004-2021 period (P < 0.0001). Males comprised 72.2% of ocular injury cases, median age was 34.5 years. The proportion of ocular injuries from road traffic collisions fell from 43.1% to 25.3% while fall-related injuries increased and predominated (37.6% in 2019/21). Concomitant head injury occurred in 86.6%. The most common site of ocular injury was the conjunctiva (29.3%). Compared to previous TARN data (1989-2004), retinal injuries were threefold more prevalent (5.9% vs 18.5%), while corneal injuries were less (31.0% vs 6.6%). CONCLUSIONS Whilst identifying eye injuries in major trauma is challenging, it appears ocular injury epidemiology in this setting has shifted, though overall prevalence is low. These findings may inform prevention strategies, guideline development and resource allocation.

Abstract
BACKGROUND Traumatic aneurysms are a rare sequela of nonaccidental head trauma in infants. The rate of nonaccidental trauma (NAT) in the pediatric population is increasing; therefore, traumatic aneurysms are an important consideration in the evaluation of pediatric patients with abusive head trauma. OBSERVATIONS A 24-day-old infant with no significant past medical or birth history presented with twitching and poor oral intake for 1 day. The patient was found to have bilateral subdural hematomas, multifocal contusions, and traumatic subarachnoid hemorrhage. NAT work-up was remarkable for a period of repeated and prolonged abuse. Magnetic resonance angiography revealed a right pericallosal traumatic aneurysm that was treated by means of coil and Onyx embolization. LESSONS Traumatic intracranial aneurysms are a rare but serious sequela of pediatric abusive trauma. Traumatic intracranial aneurysms should be considered in the setting of intracranial pathology associated with high-energy trauma. Despite new methods for the management of traumatic aneurysms, this pathology remains challenging to identify and treat, and the prognosis remains poor because of the diffuse injury often involved in these patients.

Abstract
PURPOSE OF REVIEW Musculoskeletal imaging serves a critical role in clinical care and orthopaedic research. Image-based modeling is also gaining traction as a useful tool in understanding skeletal morphology and mechanics. However, there are fewer studies on advanced imaging and modeling in pediatric populations. The purpose of this review is to provide an overview of recent literature on skeletal imaging modalities and modeling techniques with a special emphasis on current and future uses in pediatric research and clinical care. RECENT FINDINGS While many principles of imaging and 3D modeling are relevant across the lifespan, there are special considerations for pediatric musculoskeletal imaging and fewer studies of 3D skeletal modeling in pediatric populations. Improved understanding of bone morphology and growth during childhood in healthy and pathologic patients may provide new insight into the pathophysiology of pediatric-onset skeletal diseases and the biomechanics of bone development. Clinical translation of 3D modeling tools developed in orthopaedic research is limited by the requirement for manual image segmentation and the resources needed for segmentation, modeling, and analysis. This paper highlights the current and future uses of common musculoskeletal imaging modalities and 3D modeling techniques in pediatric orthopaedic clinical care and research.

Abstract
BACKGROUND Terson syndrome is the phenomenon of intraocular hemorrhage in the setting of subarachnoid hemorrhage (SAH). Vision loss can lead to morbidity for the affected individual. Aneurysmal SAH related to intracranial aneurysms is rare in children. Studies have shown the incidence of Terson syndrome in adults with aneurysmal SAH to be over 40%; however, few cases of Terson syndrome in pediatric aneurysmal SAH have been reported. OBSERVATIONS A 9-year-old male presented with altered mental status and seizures. Computed tomographic angiography showed aneurysmal SAH from a ruptured, left-sided posterior inferior cerebellar artery aneurysm. The patient underwent endovascular treatment with coiling and external ventricular drainage for SAH. Ophthalmological consultation for blurry vision revealed the diagnosis of Terson syndrome with decreased vision in the left eye, which was managed conservatively. LESSONS Terson syndrome after SAH can occur in children. Prompt ophthalmological evaluation in pediatric patients with aneurysmal SAH is vital for recognition and management to decrease overall morbidity.

Abstract
Non-accidental head trauma (NAHT) is a common cause of traumatic brain injury in childhood, origin of profound and disabling neurological sequalae, and in the most disgraceful cases, ultimately death.Subdural hematoma (SDH) is the most common intracranial finding in NAHT. On the other hand, congenital bleeding disorders are a minor but a significant cause of ICH in the neonate and toddler. Not uncommonly, intracranial bleeding is the first sign of a severe inherited coagulation disorder. In the presence of an unexpected intracranial bleeding after a minor trauma or without a clear history of the related events, physicians and caregivers may be confronted to the dilemma of a possible child abuse. It must be bear in mind that physical abuse and bleeding disorders can co-exist in the same child.We report here the case of two siblings in whom a diagnosis of hemophilia coexisted with the presumption of a non-accidental head trauma. Child abuses were inflicted in both children with a spare time of 2 years. A diagnosis of mild hemophilia was prompted in the first sibling after initial NAHT, while inflicted trauma was evident in the second sibling after neuroimaging findings and concomitant lesions. Lessons from this case in co-existing bleeding disorders and inflicted trauma and legal implications derived will be discussed thereafter.The possibility of a bleeding disorder should be considered in all children presenting with unexplained bleeding at a critical site in the setting of suspected physical maltreatment, particularly intracranial hemorrhage (ICH).

Abstract
Hyperthermia exposure is associated with poor neurological outcomes in patients with severe traumatic brain injury (TBI). Our aim was to describe fever in children with severe TBI admitted to a pediatric intensive care unit (PICU) for at least 72 hours and to evaluate associations between fever using a novel approach to describe thermal exposure and neurobehavioral outcomes. The cohort included children from birth to 17 years of age admitted to the PICU between 2000 and 2012 for at least 72 hours who had severe TBI with intracranial pressure monitoring. Patients with non-accidental TBI or pre-existing developmental delays were excluded. Hyperthermia was defined as a core temperature >37.5°C. Hourly temperature measurements were used to calculate the area under the curve (AUC) using the linear trapezoidal rule. Each participant was followed up at the Brain Injury Clinic 6 and 18 months postinjury. Neurobehavioral outcome scores were analyzed against AUC using standard statistical methods. Ninety-eight patients admitted with severe TBI met the study inclusion criteria. Hyperthermia/fever was common (89.7%), and patients remained hyperthermic for a median of 9.4 hours. However, no statistically significant association was found between AUC and abnormal neurological outcomes. The follow-up rates were good at 6 (86.7%) and 18 months (83.7%). The neurological deficit improved with time, with "favorable outcomes" increasing from 72% to 94% at the respective follow-up months. Our study used a novel method to describe patients' fever, providing a different indicator of thermal exposure than that previously reported. In addition, the AUC was well correlated with the maximum temperature recorded and the proportion of time >37.5°C, indicating that it is a good surrogate for thermal exposure. Interestingly, the neurological disabilities of the patients improved over time.

Abstract
Mild traumatic brain injury (mTBI) is common in children aged < 5 years, however, less is known about their experience of post-concussive signs and symptoms. This systematic review aims to identify post-concussive signs and symptoms experienced by preschool children up to 12 months post-injury, and to review the methods used to report this data. Relevant findings, including rates, progression, and possible predictors of post-concussive signs and symptoms were also identified. Databases (Ovid MEDLINE, EMBASE, PsycInfo, PubMed, Scopus) and reference lists were searched for relevant articles, which were screened based on specified criteria. Eleven articles met the inclusion criteria, being original studies published in English and presenting data on post-concussive signs and symptoms specific to preschool children with mTBI. Most reviewed studies investigated acute presentations of mTBI, and identified that preschool children demonstrate post-concussive symptoms (PCS) similar to other age groups. Post-traumatic amnesia duration of approximately one day was reported in preschool children following mTBI, as were changes in mood and behavior during the recovery period. Parents were the main informants, with data obtained through either interview or questionnaire. Review findings highlight the lack of empirical data regarding the presentation and progression of PCS in preschoolers following mTBI and evidence on how to best manage this group during recovery.

Abstract
The PTSD Checklist for DSM-5 (PCL-5) assessment is not meant for an acute trauma and is administered to assess PTSD symptoms experienced over the past month. This screening tool is indicated for children ages 7 or above, which spans a wider age range than does the PHQ-9. It is difficult to say how widely available psycho-trauma resources are in the acute care setting at PTCs. However, the literature demonstrates the importance of immediate, adequate psychologic care for pediatric trauma cases. We hope that trauma centers moving forward, stop only healing the broken bones and start healing the broken bones, the broken minds, and comforting the broken hearts.

Abstract
INTRODUCTION Nonaccidental trauma (NAT) is considered when pediatric patients present with intracranial injuries and a negative history of an accidental injury or concomitant medical diagnosis. The evaluation of NAT should include the consideration of possible medical causes including coagulation, hematologic, metabolic and other genetic disorders, as well as witnessed and unwitnessed accidental injuries. CASE PRESENTATION We present a 7-month-old male with spells and incidental findings of bilateral subdural hematomas, retinal hemorrhages, and secondary macrocephaly, leading to investigation for NAT. Biochemical analysis showed excretion of a large amount of D-2-hydroxyglutaric in urine consistent with a biochemical diagnosis of D-2-hydroxyglutaric aciduria, a rare neurometabolic disorder characterized by developmental delay, epilepsy, hypotonia, and psychomotor retardation. None of these symptoms were present in our patient at the time of diagnosis. Molecular genetic testing revealed a pathogenic splice site variant (c.685-2A>G) and a variant of uncertain significance (c.1256G>T) with evidence of pathogenicity in the D2HGDH gene, consistent with a molecular diagnosis of D-2-hydroxyglutaric aciduria type I (OMIM #600721). CONCLUSION Since several metabolic disorders, including D-2-hydroxyglutaric aciduria type I, can present solely with symptoms suggestive of NAT (subdural and retinal hemorrhages), an early metabolic evaluation by urine organic acid analysis should be included in clinical protocols evaluating NAT. A methodical and nonjudgmental approach coordinated between pediatricians and metabolic specialists is also necessary to ensure that rare genetic conditions are not overlooked to prevent devastating social, legal, and financial consequences of suspected child abuse.

Abstract
Child physical abuse is a leading cause of traumatic injury and death in children. In 2017, child abuse was responsible for 1688 fatalities in the United States, of 3.5 million children referred to Child Protection Services and 674,000 substantiated victims. While large referral hospitals maintain teams trained in Child Abuse Pediatrics, smaller community hospitals often do not have such dedicated resources to evaluate patients for potential abuse. Moreover, identification of abuse has a low margin of error, as false positive identifications lead to unwarranted separations, while false negatives allow dangerous situations to continue. This context makes the consistent detection of and response to abuse difficult, particularly given subtle signs in young, non-verbal patients. Here, we describe the development of artificial intelligence algorithms that use unstructured free-text in the electronic medical record-including notes from physicians, nurses, and social workers-to identify children who are suspected victims of physical abuse. Importantly, only the notes from time of first encounter (e.g.: birth, routine visit, sickness) to the last record before child protection team involvement were used. This allowed us to develop an algorithm using only information available prior to referral to the specialized child protection team. The study was performed in a multi-center referral pediatric hospital on patients screened for abuse within five different locations between 2015 and 2019. Of 1123 patients, 867 records were available after data cleaning and processing, and 55% were abuse-positive as determined by a multi-disciplinary team of clinical professionals. These electronic medical records were encoded with three natural language processing (NLP) algorithms-Bag of Words (BOW), Word Embeddings (WE), and Rules-Based (RB)-and used to train multiple neural network architectures. The BOW and WE encodings utilize the full free-text, while RB selects crucial phrases as identified by physicians. The best architecture was selected by average classification accuracy for the best performing model from each train-test split of a cross-validation experiment. Natural language processing coupled with neural networks detected cases of likely child abuse using only information available to clinicians prior to child protection team referral with average accuracy of 0.90±0.02 and average area under the receiver operator characteristic curve (ROC-AUC) 0.93±0.02 for the best performing Bag of Words models. The best performing rules-based models achieved average accuracy of 0.77±0.04 and average ROC-AUC 0.81±0.05, while a Word Embeddings strategy was severely limited by lack of representative embeddings. Importantly, the best performing model had a false positive rate of 8%, as compared to rates of 20% or higher in previously reported studies. This artificial intelligence approach can help screen patients for whom an abuse concern exists and streamline the identification of patients who may benefit from referral to a child protection team. Furthermore, this approach could be applied to develop computer-aided-diagnosis platforms for the challenging and often intractable problem of reliably identifying pediatric patients suffering from physical abuse.

Pediatric Nonaccidental Trauma: Experience at a Level 1 Trauma Center. Int J Pediatr 2020; 2020:6621992. [PMID: 33456474 PMCID: PMC7785376 DOI: 10.1155/2020/6621992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 12/13/2020] [Accepted: 12/15/2020] [Indexed: 11/18/2022] Open
Abstract
Introduction Pediatric nonaccidental trauma (NAT) is difficult to diagnose. Several isolated injuries in NAT could happen in the setting of accidental trauma (AT), and having a high index of suspicion is important to correctly identify abuse. NAT has a significant mortality rate if the sentinel event is not adequately diagnosed, and the infant is not separated from the perpetrator. Level 1 pediatric trauma centers (PTC) see a significant number of NAT. We evaluated the injury patterns of NAT admissions at our level 1 PTC. Methods Retrospective analysis of all cases of NAT for children under the age of two admitted at an ACS level 1 pediatric trauma center between the years of 2016 and 2018. Charts were queried for demographic data, injury patterns, mortality, and disposition. Correlation between disposition status and injury patterns was performed. The Fisher Exact test and student t-test were used to study the significance of differences in categorical and continuous data, respectively. Results 32/91 (35%) trauma patients under the age of two years were diagnosed as NAT in the three-year study period. 21/32 (39%) male and 11/26 (42%) female admissions were confirmed NAT (p = NS). 20 were under 1 year of age, and 12 were aged between 1 and 2 years (p = NS). 13 (41%) were Caucasian, 6 (19%) were Hispanic/Latino, 11 (34%) were Black, and 2(6%) were of unknown ethnicity (p = NS). Facial, torso, lower extremity, retinal, and internal organ injury were significantly more common with NAT. Medicaid coverage was noted in 31/32 (97%) NAT patients. 20/32 (62.5%) patients were legally displaced as a result of the NAT. Conclusion 1/3rd of all admissions at a pediatric level 1 trauma center were identified as NAT. A high index of suspicion is necessary to not miss NAT, as injury patterns are variable. Nearly 1/3rd of all victims go back to the same environment where they sustained NAT increasing their susceptibility to future NAT.

Abstract
Abusive head trauma (AHT), used to be named shaken baby syndrome, is an injury to the skull and intracranial components of a baby or child younger than 5 years due to violent shaking and/or abrupt impact. It is a worldwide leading cause of fatal head injuries in children under 2 years. The mechanism of AHT includes shaking as well as impact, crushing or their various combinations through acceleration, deceleration and rotational force. The diagnosis of AHT should be based on the existence of multiple components including subdural hematoma, intracranial pathology, retinal hemorrhages as well as rib and other fractures consistent with the mechanism of trauma. The differential diagnosis must exclude those medical or surgical diseases that can mimic AHT such as traumatic brain injury, cerebral sinovenous thrombosis, and hypoxic-ischemic injury. As for the treatment, most of the care of AHT is supportive. Vital signs should be maintained. Intracranial pressure, if necessary, should be monitored and controlled to ensure adequate cerebral perfusion pressure. There are potential morbidity and mortality associated with AHT, ranging from mild learning disabilities to severe handicaps and death. The prognosis of patients with AHT correlates with the extent of injury identified on CT and MRI imaging. The outcome is associated with the clinical staging, the extent of increased intracranial pressure and the existence of neurological complications such as acquired hydrocephalus or microcephalus, cortical blindness, convulsive disorder, and developmental delay. AHT is a potentially preventable disease, therefore, prevention should be stressed in all encounters within the family, the society and all the healthcare providers.

Abstract
Background
The aim of this study was to assess deformational plagiocephaly’s (DP) predictive value in neglect and physical abuse (nonaccidental trauma [NAT]) within the pediatric population. In addition, we sought to characterize the prevalence of DP and NAT for our hospital’s mostly rural catchment area.
Methods
Data on hospitalized patients diagnosed with NAT and/or neglect between 2012 and 2018 were collected via retrospective chart review. All enrolled children were younger than the age of 4 years at the time of diagnosis, and those without legible head computed tomographies or magnetic resonance images during their initial hospitalization were excluded. Utilizing neuroimaging, we calculated the cranial vault asymmetry index (CVAI) and cranial index for each patient to assess for DP. Differences between the two groups were assessed using Wilcoxon’s rank-sum test for continuous variables and Fisher’s exact test for categorical variables. A
p
-value of 0.05 or less was considered statistically significant. All analyses were conducted using SAS 9.4 (Cary, North Carolina, United States).
Results
The prevalence of DP within the combined cohort of NAT and neglect patients is 21%, similar to that reported in the literature for the general population (20–50%). There was no significance between the prevalence of DP and a history of NAT (
p
> 0.1) or neglect (
p
> 0.1). Furthermore, there was no correlation between CVAI and characteristics of initial presentation or history of trauma for either NAT (
p
-values: 0.359 and 0.250, respectively) or neglect groups (
p
-values: 0.116 and 0.770, respectively).
Conclusion
While there are many limitations to this study, our results suggest that abused children are no more likely to have history of DP than the general population, and the degree of DP is not associated with severity of trauma history or initial presentation. We hope the results of this study promote future investigations for unique and subtle predictive factors of child abuse/neglect.

Abstract
Abusive head trauma (AHT) is broadly defined as injury of the skull and intracranial contents as a result of perpetrator-inflicted force and represents a persistent and significant disease burden in children under the age of 4 years. When compared to age-matched controls with typically single occurrence accidental traumatic brain injury (TBI), mortality after AHT is disproportionately high and likely attributable to key differences between injury phenotypes. This article aims to review the epidemiology of AHT, summarize the current state of AHT diagnosis, treatment, and prevention as well as areas for future directions of study. Despite neuroimaging advances and an evolved understanding of AHT, early identification remains a challenge for contemporary clinicians. As such, the reported incidence of 10–30 per 100,000 infants per year may be a considerable underestimate that has not significantly decreased over the past several decades despite social campaigns for public education such as “Never Shake a Baby.” This may reflect caregivers in crisis for whom education is not sufficient without support and intervention, or dangerous environments in which other family members are at risk in addition to the child. Acute management specific to AHT has not advanced beyond usual supportive care for childhood TBI, and prevention and early recognition remain crucial. Moreover, AHT is frequently excluded from studies of childhood TBI, which limits the precise translation of important brain injury research to this population. Repeated injury, antecedent abuse or neglect, delayed medical attention, and high rates of apnea and seizures on presentation are important variables to be considered. More research, including AHT inclusion in childhood TBI studies with comparisons to age-matched controls, and translational models with clinical fidelity are needed to better elucidate the pathophysiology of AHT and inform both clinical care and the development of targeted therapies. Clinical prediction rules, biomarkers, and imaging modalities hold promise, though these have largely been developed and validated in patients after clinically evident AHT has already occurred. Nevertheless, recognition of warning signs and intervention before irreversible harm occurs remains the current best strategy for medical professionals to protect vulnerable infants and toddlers.

Abstract
OBJECTIVE We sought: 1) to examine the association between the presence of a child abuse pathway and the odds of skeletal survey performance in infants with injuries associated with high risk of abuse and 2) to determine whether pathway presence decreased disparities in skeletal survey performance. METHODS: In this retrospective study of children <1 year diagnosed with injuries associated with high risk of abuse at hospitals in the Pediatric Hospital Information System, information regarding the presence of a child abuse pathway was collected via survey. We examined whether the presence of a child abuse pathway was associated with the odds of obtaining a skeletal survey, adjusting for patient-level factors. RESULTS: Among 2085 included cases 55% were male, 69% had public insurance, and 64% were white. Fifty-eight percent presented to a hospital when a pathway was present. Skeletal surveys were performed in 86% of children between 0 and 5 months and 73% of children 6-11 months. In our regression model, adjusted for covariates (age, race, insurance, injury) the presence of a child abuse pathway in a hospital was associated with greater odds of skeletal survey performance (odds ratio [OR], 1.46, 95% confidence interval [CI], 1.02-2.08). Children with public insurance had greater odds of receiving a skeletal survey (OR 2.75, 95% CI 2.11-3.52) despite presence of pathway. CONCLUSIONS: When a child abuse clinical pathway was present, children with injuries associated with a high risk of abuse had a greater odds of receiving a skeletal survey. Differences in skeletal survey performance exist between infants with public vs. private insurance regardless of a pathway.

Abstract
Child abuse remains a significant issue. Non-accidental head injury (NAHI) is a major cause of mortality in young children with survivors often having to live a life with severe developmental and neurological dysfunction. The aim of this hermeneutic phenomenological research study was to examine the lived experiences of nurses who care for children and their families admitted to hospital with a non-accidental head injury. Semi-structured interviews were conducted with six nurses who had at least five years' experience of nursing children with NAHI. Following the interpretive approach described by van Manen data was analyzed and two essential themes identified. Firstly, nursing children with NAHI is different from the care of children admitted with a similar neurological injury related to accidental injuries or medical conditions. Secondly, when nursing these children nurses adopt protective qualities, conceptualized in this study as a shield of protection. The findings of this study support the findings of other studies in regard to the emotional labor required of nurses caring for children who have been subject to child abuse and the importance for nurses of maintaining a professional demeanor. The study highlighted the tensions of sustaining a family-centered care approach when caring for a child with NAHI. It is argued that greater acknowledgment and emotional support for nurses is needed and that a child-centered approach offers a more compatible model of care than Family-Centered Care in the acute phase of caring for children with a NAHI.

Abstract
OBJECTIVES Nonaccidental trauma (NAT) is a leading cause of pediatric mortality and disability. We examined our institution's experience with NAT to determine if socioeconomic status is correlated with patient outcomes. METHODS NAT cases were reviewed retrospectively. Socioeconomic determinants included insurance status and race; outcomes included mortality, discharge disability and disposition. Correlations were identified using t test, Fisher's exact test, and logistic regression. RESULTS The cohort comprised of 337 patients, with an overall uninsured rate of 5.6%. This rate was achieved by insuring 64.7% of the cohort after admission. Non-survivors were more likely to have no insurance coverage (14.8% versus 4.8%, p = 0.041). Regression revealed that uninsured had 8 times (95% CI 1.7-38.7, p = 0.008) higher in-hospital mortality than those with insurance when controlling for injury severity. Additionally, injury severity score ≥ 15, transfer from outside hospital, need for ICU or operative treatment were predictive of mortality. Adjusted risk factors for severe disability at discharge did not include insurance status or race, while ISS ≥ 15 and ICU stay were predictive. CONCLUSIONS There are significant associations of insurance status with pediatric NAT outcomes, highlighting that determinants other than disease severity may influence mortality and morbidity. High-risk patients should be identified to develop strategies to improve outcomes.

Abstract
Traumatic brain injury (TBI) is a significant cause of mortality and disability in the pediatric population. Non-accidental trauma (NAT) has specifically been reported to result in more severe injury as compared to accidental mechanisms of injury. We aim to investigate the long-term neurological outcomes in children with moderate to severe traumatic brain injury. Our secondary aim is to evaluate the difference in outcomes between children presenting with NAT and non-NAT, in our study population. We performed a retrospective study in a tertiary pediatric hospital between January 2008 to October 2017 of all patients with TBI <16 years old with a Glasgow Coma Scale (GCS) ≤13. The dual primary outcomes were mortality and Paediatric Functional Independence Measure (WeeFIM) scores, recorded at the start of rehabilitation, discharge, 3 months and 6 months post-injury. The secondary outcome was the development of post-traumatic epilepsy. There were 68 patients with a median age of 4.5 [interquartile range (IQR) 1.0-9.0] years old. The most common presenting symptom was vomiting for children <2 years (11/20, 55.0%) while confusion and disorientation were common for those ≥2 years (27/48, 56.3%). WeeFIM scores at the start of rehabilitation [median 122.0, IQR 33.8-126.0] improved at 6 months post-injury (median 126.0, IQR 98.5-126.0). There was a greater incidence of post-traumatic epilepsy in age <2 years (6/20, 30.0%) compared to age ≥2 years (1/48, 2.1%) (p = .002). When comparing NAT versus non-NAT survivors, cognition WeeFIM scores were significantly different at the start of rehabilitation (p = .017) and at 3 months post-injury (p = .025). NAT predicts for poorer long-term outcomes, specifically in cognition, as measured by WeeFIM scores. Younger children <2 years had a higher incidence of post-traumatic epilepsy compared to older children.

Abstract
Anoxic brain injury on magnetic resonance imaging classically demonstrates symmetric diffusion restriction involving the highly metabolic structures including the basal ganglia and cortex and global hyperperfusion on arterial spin labeling perfusion. The pattern of injury is classically diffuse and bilateral owing to global oxygen deprivation from systemic causes, most commonly cardiac arrest. In cases of suspected nonaccidental trauma presenting with a unilateral anoxic injury pattern, strangulation with temporary occlusion of a unilateral carotid artery should be considered. We present 2 cases of unilateral anoxic brain injury due to strangulation identified on magnetic resonance imaging and arterial spin labeling perfusion.
