Wilderness Environ Med 2023; 34:45-54. [PMID: 36610917 DOI: 10.1016/j.wem.2022.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 09/15/2022] [Accepted: 10/14/2022] [Indexed: 01/07/2023]
Abstract
INTRODUCTION Skiing and snowboarding are popular winter sports with significant youth participation and inherent potential for injury. We investigated the relationship between age and injury characteristics exhibited by youth skiers and snowboarders. METHODS In this cross-sectional study, we investigated injury characteristics among youth skiers and snowboarders at a ski resort, examining the association between age and injury type. We compared injury characteristics among young children (aged 3-6 y), school-aged children (aged 7-14 y), and older adolescents (aged 15-17 y) using χ2, and examined predictive variables for injuries at different anatomical locations using logistic regression. RESULTS Compared with snowboarding, skiing was associated with greater odds of lower extremity (adjusted odds ratio [aOR]=6.8, 95% confidence interval [CI]: 4.89, 9.47, P<0.001) and head/face/neck (aOR=1.63, 95% CI: 1.20, 2.21, P=0.002) injuries. Compared with skiing, snowboarding was associated with greater odds of upper extremity injury (aOR=5.9, 95% CI: 4.6, 7.6, P<0.001). Age group significantly affected injury mechanism (χ2 [df=12, n=1129]=42.882, P<0.0001) and diagnosis (χ2 [df=12, n=1129]=43.093, P<0.0001). Young child skiers had the highest proportion of injuries to the head/neck/face and lower extremities and a significantly higher proportion of collision injuries and fractures than older skiers. Young child skiers most frequently injured the lower leg/ankle, while older skiers most frequently injured the knee. CONCLUSIONS Youth skiers exhibited predominately lower extremity injuries, while snowboarders exhibited predominately upper extremity injuries. Age significantly affected injury mechanism and injury diagnosis in youth skiers. Specifically, younger skiers tended to suffer more fractures and collision injuries than older youth skiers.

Abstract
BACKGROUND We aimed to determine the outcomes and prognostic factors in pediatric craniocerebral gunshot injury (CGI) patients. Pediatric patients may have significantly different physiology, neuroplasticity, and clinical outcomes in CGI than adults. There is limited literature on this topic, mainly case reports and small case series. METHODS We queried the National Trauma Data Bank for all pediatric CGI between 2014 and 2017. Patients were identified using International Classification of Diseases, Ninth Revision, codes. Demographic, emergency department, and clinical data were analyzed. Subgroup analysis was attempted for groups with Glasgow Coma Scale (GCS) scores of 9 to 15 and ages 0 to 8 years. RESULTS In a 3-year period, there were 209 pediatric patients (aged 0-18 years) presenting to American hospitals with signs of life. The overall mortality rate was 53.11%. A linear relationship was demonstrated showing a mortality rate of 79% by initial GCS in GCS score of 3, 56% in GCS scores of 4 to 8, 22% in GCS scores of 9 to 12, and 5% in GCS scores of 13 to 15. The youngest patients, aged 0 to 8 years, had dramatically better initial GCS and subsequently lower mortality rates. Regression analysis showed mortality benefit in the total population for intracranial pressure monitoring (odds ratio, 0.267) and craniotomy (odds ratio, 0.232). CONCLUSION This study uses the National Trauma Data Bank to quantify the prevalence of pediatric intracranial gunshot wounds, with the goal to determine risk factors for prognosis in this patient population. Significant effects on mortality for invasive interventions including intracranial pressure monitoring and craniotomy for all patients suggest low threshold for use of these procedures if there is any clinical concern. The presence of a 79% mortality rate in patients with GCS score of 3 on presentation suggests that as long as there is not a declared neurologic death, intracranial pressure monitoring and treatment measures including craniotomy should be considered by the consulting clinician. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

Abstract
INTRODUCTION Mild traumatic brain injury (mTBI) is highly prevalent, especially in children under 6 years. However, little research focuses on the consequences of mTBI early in development. The objective of the Kids' Outcomes And Long-term Abilities (KOALA) study is to document the impact of early mTBI on children's motor, cognitive, social and behavioural functioning, as well as on quality of life, stress, sleep and brain integrity. METHODS AND ANALYSES KOALA is a prospective, multicentre, longitudinal cohort study of children aged 6 months to 6 years at the time of injury/recruitment. Children who sustain mTBI (n=150) or an orthopaedic injury (n=75) will be recruited from three paediatric emergency departments (PEDs), and compared with typically developing children (community controls, n=75). A comprehensive battery of prognostic and outcome measures will be collected in the PED, at 10 days, 1, 3 and 12 months postinjury. Biological measures, including measures of brain structure and function (magnetic resonance imaging, MRI), stress (hair cortisol), sleep (actigraphy) and genetics (saliva), will complement direct testing of function using developmental and neuropsychological measures and parent questionnaires. Group comparisons and predictive models will test the a priori hypotheses that, compared with children from the community or with orthopaedic injuries, children with mTBI will (1) display more postconcussive symptoms and exhibit poorer motor, cognitive, social and behavioural functioning; (2) show evidence of altered brain structure and function, poorer sleep and higher levels of stress hormones. A combination of child, injury, socioenvironmental and psychobiological factors are expected to predict behaviour and quality of life at 1, 3 and 12 months postinjury. ETHICS AND DISSEMINATION The KOALA study is approved by the Sainte-Justine University Hospital, McGill University Health Centre and University of Calgary Conjoint Health Research Ethics Boards. Parents of participants will provide written consent. Dissemination will occur through peer-reviewed journals and an integrated knowledge translation plan.

Abstract
BACKGROUND Pediatric craniocerebral gunshot injuries (CGIs) occur both in the context of accidental and intentional trauma. The incidence and physiology of pediatric CGIs merit reexamination of prognostic factors and treatment priorities. This study characterizes the current understanding of mortality and prognostic factors in this patient population. METHODS A systematic search was conducted. Selection criteria included all studies published since 2000, which described civilian isolated CGIs in pediatric patients. Data were analyzed qualitatively and quantitatively to identify factors prognostic for the primary outcome of mortality. Secondary outcomes included functional outcome status, requirement for surgery, and injury complications. Study quality was assessed with the Newcastle-Ottawa Scale. This study was registered with PROSPERO (CRD42019134231). RESULTS Initial search revealed 349 unique studies. Forty underwent full text screening, and eight studies were included in the final synthesis. The overall mortality rate was 44.8%. Most CGIs occurred in older teenagers. Aggressive surgical treatment was recommended by one author, while remaining studies emphasized clinical judgment. Reported prognostic factors include initial Glasgow Coma Scale, pupil reactivity, involvement of multiple lobes or deep nuclei, and bihemispheric injuries. Reported complications from CGIs included seizure, meningitis, abscess, cerebrospinal fluid leak, bullet migration, focal neurological deficits, endocrine abnormalities, cognitive deficits, and neuropsychological deficits. The Glasgow Outcome Scale was the predominant measure of function and demonstrated a moderate recovery in 17.4% and a good recovery in 27.3% of patients. CONCLUSION This systematic review analyzed the existing evidence for prognostic factors in the context of pediatric CGIs. Significant long-term clinical improvement is possible with interventions including urgent surgical therapy. Fixed bilateral pupils and low initial Glasgow Coma Scale correlate with mortality but do not predict all patient outcomes. Patients younger than 15 years are underreported and may have differences in outcome. The literature on pediatric CGIs is limited and requires further characterization. LEVEL OF EVIDENCE Systematic Review, level IV.

Abstract
We determined if heme oxygenase-2 (HO-2), an enzyme that degrades the pro-oxidant heme, confers neuroprotection in the developing brain after traumatic brain injury (TBI). Male HO-2 wild-type (WT) and homozygous knockout (KO) mice at postnatal day 21 were subjected to TBI and euthanized 1, 7, and 14 days later. Relative cerebral blood flow, measured by laser Doppler, cortical and hippocampal pathogenesis, and motor recovery were evaluated at all time points. Cerebral blood flow was found to be similar between experimental groups. Blood flow significantly decreased immediately after injury, returned to baseline by 1 day, and was significantly elevated by 7 days, post-injury. Nonheme iron preferentially accumulated in the ipsilateral cortex, hippocampus, and external capsule in both WT and KO brain-injured genotypes. There were, however, a significantly greater number of TUNEL-positive cells in the hippocampal dentate gyrus and a significantly greater cortical lesion volume in KOs relative to WTs within the first week post-injury. By 14 days post-injury, however, cortical lesion volume and cell density in the hippocampal CA3 region and dorsal thalamus were similar between the two groups. Assays of fine motor function (grip strength) over the first 2 weeks post-injury revealed a general pattern of decreased strength in the contralateral forelimbs of KOs as compared to WTs. Together, these findings demonstrate that deficiency in HO-2 alters both the kinetics of secondary damage and fine motor recovery after TBI.

Abstract
Each year, pediatric traumatic brain injury (TBI) accounts for 435,000 emergency department visits, 37,000 hospital admissions, and approximately 2,500 deaths in the United States. TBI results in immediate injury from direct mechanical force and shear. Secondary injury results from the release of biochemical or inflammatory factors that alter the loco-regional milieu in the acute, subacute, and delayed intervals after a mechanical insult. Preliminary preclinical and clinical research is underway to evaluate the benefit from progenitor cell therapeutics, hypertonic saline infusion, and controlled hypothermia. However, all phase III clinical trials investigating pharmacologic monotherapy for TBI have shown no benefit. A recent National Institutes of Health consensus statement recommends research into multimodality treatments for TBI. This article will review the complex pathophysiology of TBI as well as the possible therapeutic mechanisms of progenitor cell transplantation, hypertonic saline infusion, and controlled hypothermia for possible utilization in multimodality clinical trials.

Abstract
OBJECTIVE The cholinergic system is highly vulnerable to traumatic brain injury (TBI). However, limited information is available to what extent the degrading enzyme acetylcholinesterase (AChE) is involved. The present study addresses this question. METHOD Thirty-six anaesthetized Sprague-Dawley rats were subjected to sham operation or to TBI using controlled cortical impact (CCI). The AChE activity was histochemically determined in frozen brain slices at 2, 24 and 72 hours after TBI. RESULTS High enzyme activity was observed in regions rich in cholinergic innervation such as the olfactory tubercle, basal forebrain, putamen and superior colliculi. Low activity was found in the cortex, cerebellum and particularly in the white matter. A decrease of AchE activity (20-35%) was found in the hippocampus and hypothalamus already at 2 hours after TBI. An increase of approximately 30% was found in the basal forebrain at 2 and 24 hours. No changes occurred at 72 hours. CONCLUSION The findings are consistent with impairment of the cholinergic neurotransmission after TBI and suggest the involvement of the AChE in short-term regulatory mechanisms.
