Abstract
Invasive neuromonitoring has become an important part of pediatric neurocritical care, as neuromonitoring devices provide objective data that can guide patient management in real time. New modalities continue to emerge, allowing clinicians to integrate data that reflect different aspects of cerebral function to optimize patient management. Currently, available common invasive neuromonitoring devices that have been studied in the pediatric population include the intracranial pressure monitor, brain tissue oxygenation monitor, jugular venous oximetry, cerebral microdialysis, and thermal diffusion flowmetry. In this review, we describe these neuromonitoring technologies, including their mechanisms of function, indications for use, advantages and disadvantages, and efficacy, in pediatric neurocritical care settings with respect to patient outcomes.

Abstract
Abusive head trauma (AHT) refers to a well-recognized constellation of injuries caused by the direct application of force to an infant or young child, resulting in trauma to the head, intracranial contents, and/or neck, with potentially devastating health outcomes. Mechanisms of AHT include impulsive injurious acts, such as violent shaking and impact, often due to caregiver frustration or exhaustion. Subdural and retinal hemorrhage, and associated extracranial injury (fractures, abdominal trauma), are common. Suspected victims require laboratory/diagnostic testing and occult injury screening, as well as protective measures by investigative authorities to ensure safety. Medicolegal controversies persist around AHT diagnosis, including alternative hypotheses proffered in court by skeptics despite advances in scientific understanding, biomechanical research, neuroimaging techniques, and perpetrator confessions. Pediatricians play a key role in prevention and reduction of AHT morbidity and mortality through anticipatory guidance and caregiver education about the risks of shaking, normal infant development and behavior, and encouragement of stress reduction strategies.

Abstract
OBJECTIVES Traumatic brain injury is a leading cause of hospital visits for children. Hyperosmolar therapy is often used to treat severe traumatic brain injury. Hypertonic saline is used predominantly, yet there remains disagreement about whether hypertonic saline or mannitol is more effective. DATA SOURCES Literature search was conducted using Pubmed, Cochrane, and Embase. Systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. STUDY SELECTION Retrospective and prospective studies assessing use of hyperosmolar therapy in pediatric patients with severe traumatic brain injury were included. DATA EXTRACTION Two independent authors performed article review. Two-thousand two-hundred thirty unique articles were initially evaluated, 11 were included in the final analysis, with a total of 358 patients. Study quality was assessed using Modified Newcastle-Ottawa Scale and Jadad score. DATA SYNTHESIS Of the 11 studies, all evaluated hypertonic saline and four evaluated both hypertonic saline and mannitol. Nine reported that hypertonic saline lowered intracranial pressure and two reported that mannitol lowered intracranial pressure. The studies varied significantly in dose, concentration, and administrations schedule for both hypertonic saline and mannitol. Five studies were prospective, but only one directly compared mannitol to hypertonic saline. The prospective comparison study found no difference in physiologic outcomes. Clinical outcomes were reported using different measures across studies. For hypertonic saline-treated patients, mechanical ventilation was required for 6.9-9 days, decompressive craniectomy was required for 6.25-29.3% of patients, ICU length of stay was 8.0-10.6 days, in-hospital mortality was 10-48%, and 6-month mortality was 7-17%. In mannitol-treated patients, ICU length of stay was 9.5 days, in-hospital mortality was 56%, and 6-month mortality was 19%. CONCLUSIONS Both hypertonic saline and mannitol appear to lower intracranial pressure and improve clinical outcomes in pediatric severe traumatic brain injury, but the evidence is extremely fractured both in the method of treatment and in the evaluation of outcomes. Given the paucity of high-quality data, it is difficult to definitively conclude which agent is better or what treatment protocol to follow.

Abstract
OBJECTIVE Describe outcomes associated with bolus and continuous infusions of hypertonic saline (HTS) in children with severe traumatic brain injury (TBI). METHODS IRB-approved, single-center, retrospective review of children admitted between January 1, 2012 to August 30, 2018 with a diagnosis of severe TBI who received HTS. RESULTS Forty-five children (age 9.3 ± 5.8 yr; 60% male) met inclusion criteria. One-hundred eighty-nine equiosmolar bolus doses of HTS were administered to 43 patients (3% HTS, n = 84 doses; 6% HTS, n = 38 doses; 12% HTS, n = 67 doses) for episodes of acute intracranial hypertension (pressure above 20 mmHg). Significant reductions in ICP were observed at 30, 60, and 120 min following HTS boluses with the greatest decrease observed in patients receiving 12%. Thirty-four patients received a continuous infusion of HTS. Higher concentrations of HTS were associated with a more favorable fluid balance (p < .001), fewer episodes of pulmonary edema (p = .003), and higher intake of protein and energy (p < .001). CONCLUSIONS Equiosmolar bolus doses of concentrated HTS were associated with significant reductions in ICP. Benefits of higher concentrations of continuous HTS may include improved fluid balance, less pulmonary edema, and greater amounts of protein and energy intake.

Abstract
OBJECTIVE To explore the effect of 23.4% hypertonic saline for management of elevated intracranial pressure in children admitted to our institution for severe traumatic brain injury. DESIGN Single-center, retrospective medical chart analysis. SETTING A PICU at a level 1 pediatric trauma center in the United States. PATIENTS Children admitted for severe traumatic brain injury from 2006 to 2016 who received 23.4% hypertonic saline and whose intracranial pressures were measured within 5 hours of receiving 23.4% hypertonic saline. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Over the 10-year period, 1,587 children were admitted for traumatic brain injury, 155 of whom were deemed severe per this study's criteria. Forty of these children received at least one dose of hypertonic saline, but 14 were excluded for insufficient intracranial pressure data. Among the remaining 26 children, one hundred one 23.4% hypertonic saline boluses were used in the analysis. Use of 23.4% hypertonic saline was associated with a decrease in intracranial pressure of approximately 7 mm Hg at both within 1 hour after the bolus (p < 0.01) and 4 hours after the bolus (p < 0.01) when compared with the intracranial pressure measured within 1 hour before the hypertonic saline bolus. These effects remained significant after adjusting for Functional Status Scale score and CT Marshall scores. There was no statistically significant association between adjunctive therapies, such as antiepileptics and analgesics, and changes in intracranial pressure. There was no laboratory evidence of hyperkalemia or renal injury after use of 23.4% hypertonic saline. Across all hospitalizations, 65% of the study population demonstrated an abnormally elevated creatinine at least once, but only three episodes of acute kidney injury occurred in total, all before hypertonic saline administration. Eight of the 26 children in this analysis died during their hospitalization. The Functional Status Scale scores ranged from 6 to 26 with a mean of 12.2 and SD of 5.7. CONCLUSIONS Use of 23.4% hypertonic saline with children admitted for severe traumatic brain injury is associated with a statistically significant decrease in intracranial pressure within 1 hour of use.

Abstract
PURPOSE German pediatric guidelines for severe traumatic brain injury (TBI) management expired in 2011. Thus, divergent evidence-based institutional protocols are predominantly being followed. We performed a survey of current Pediatric Intensive Care Unit (PICU) management of isolated severe TBI in Germany to reveal potential varying practices. METHODS Seventy German PICUs were invited to join an anonymous online survey from February to May 2017. Twenty-nine participants (41.4%) successfully completed the survey (17 university hospitals and 12 district hospitals). The majority of items were polar (yes/no) or scaled (e.g., never - always). Main topics were imaging, neurosurgery, neuromonitoring, adjuvant therapy, and medication. Severity of TBI was defined via Glasgow Coma Scale. RESULTS The majority of respondents (93.1%) had internal TBI standards, and patients were mainly administered to interdisciplinary trauma units. The use of advanced neuromonitoring techniques, intracranial hypertension management, and drug treatment differed between PICUs. Routine administration of hypertonic saline in TBI-associated cerebral edema was performed by 3.4%, while it was never an option for 31.0% of the participants. Prophylactic anticonvulsive therapy was restrictively performed. If indicated, the main anticonvulsive drugs used were phenobarbital and levetiracetam. Neuroendocrine follow-up was recommended/performed by 58.6% of the PICUs. CONCLUSIONS This survey provides an overview of the current PICU practices of isolated severe TBI management in Germany and demonstrates a wide instrumental and therapeutical range, revealing an unmet need for the revised national guideline and further (international) clinical trials for the treatment of severe TBI in pediatrics.

Abstract
Pediatric traumatic brain injury (TBI) remains one of the leading causes of morbidity and mortality in children. Experimental and clinical studies demonstrate that the developmental age, the type of injury (diffuse vs. focal) and sex may play important roles in the response of the developing brain to a traumatic injury. Advancements in acute neurosurgical interventions and neurocritical care have improved and led to a decrease in mortality rates over the past decades. However, survivors are left with life-long behavioral deficits underscoring the need to better define the cellular mechanisms underlying these functional changes. A better understanding of these mechanisms some of which begin in the acute post-traumatic period may likely lead to targeted treatment strategies. Key considerations in designing pre-clinical experiments to test therapeutic strategies in pediatric TBI include the use of age-appropriate and pathologically-relevant models, functional outcomes that are tested as animals age into adolescence and beyond, sex as a biological variable and the recognition that doses and dosing strategies that have been demonstrated to be effective in animal models of adult TBI may not be effective in the developing brain. This article is part of the Special Issue entitled "Novel Treatments for Traumatic Brain Injury".

Abstract
The term "Big Black Brain" was first coined in 1993 to describe cases of abusive head trauma associated with subdural hematoma(s), brain swelling, and uni- or bilateral hypo-density involving the entire supratentorial compartment on CT scan imaging. This constellation of findings was invariably followed by extensive cerebral parenchymal destruction and a dismal neurological outcome or death. We describe two such cases and review the pathophysiology and differential diagnosis of this entity.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a major public health problem and a fundamental cause of morbidity and mortality worldwide. The burden of TBI disproportionately affects low- and middle-income countries. Intracranial hypertension is the most frequent cause of death and disability in brain-injured people. Special interventions in the intensive care unit are required to minimise factors contributing to secondary brain injury after trauma. Therapeutic positioning of the head (different degrees of head-of-bed elevation (HBE)) has been proposed as a low cost and simple way of preventing secondary brain injury in these people. The aim of this review is to evaluate the evidence related to the clinical effects of different backrest positions of the head on important clinical outcomes or, if unavailable, relevant surrogate outcomes. OBJECTIVES To assess the clinical and physiological effects of HBE during intensive care management in people with severe TBI. SEARCH METHODS We searched the following electronic databases from their inception up to March 2017: Cochrane Injuries' Specialised Register, CENTRAL, MEDLINE, Embase, three other databases and two clinical trials registers. The Cochrane Injuries' Information Specialist ran the searches. SELECTION CRITERIA We selected all randomised controlled trials (RCTs) involving people with TBI who underwent different HBE or backrest positions. Studies may have had a parallel or cross-over design. We included adults and children over two years of age with severe TBI (Glasgow Coma Scale (GCS) less than 9). We excluded studies performed in children of less than two years of age because of their unfused skulls. We included any therapeutic HBE including supine (flat) or different degrees of head elevation with or without knee gatch or reverse Trendelenburg applied during the acute management of the TBI. DATA COLLECTION AND ANALYSIS Two review authors independently checked all titles and abstracts, excluding references that clearly didn't meet all selection criteria, and extracted data from selected studies on to a data extraction form specifically designed for this review. There were no cases of multiple reporting. Each review author independently evaluated risk of bias through assessing sequence generation, allocation concealment, blinding, incomplete outcome data, selective outcome reporting, and other sources of bias. MAIN RESULTS We included three small studies with a cross-over design, involving a total of 20 participants (11 adults and 9 children), in this review. Our primary outcome was mortality, and there was one death by the time of follow-up 28 days after hospital admission. The trials did not measure the clinical secondary outcomes of quality of life, GCS, and disability. The included studies provided information only for the secondary outcomes intracranial pressure (ICP), cerebral perfusion pressure (CPP), and adverse effects.We were unable to pool the results as the data were either presented in different formats or no numerical data were provided. We included narrative interpretations of the available data.The overall risk of bias of the studies was unclear due to poor reporting of the methods. There was marked inconsistency across studies for the outcome of ICP and small sample sizes or wide confidence intervals for all outcomes. We therefore rated the quality of the evidence as very low for all outcomes and have not included the results of individual studies here. We do not have enough evidence to draw conclusions about the effect of HBE during intensive care management of people with TBI. AUTHORS' CONCLUSIONS The lack of consistency among studies, scarcity of data and the absence of evidence to show a correlation between physiological measurements such as ICP, CCP and clinical outcomes, mean that we are uncertain about the effects of HBE during intensive care management in people with severe TBI.Well-designed and larger trials that measure long-term clinical outcomes are needed to understand how and when different backrest positions can affect the management of severe TBI.

Abstract
Analgosedation is a fundamental part of traumatic brain injury (TBI) treatment guidelines, encompassing both first and second tier supportive strategies. Worldwide analgosedation practices continue to be heterogeneous due to the low level of evidence in treatment guidelines (level III) and the choice of analgosedative drugs is made by the treating clinician. Current practice is thus empirical and may result in unfavourable (often hemodynamic) side effects. This article presents an overview of current analgosedation practices in the paediatric intensive care unit (PICU) and addresses pitfalls both in the short and long term. We discuss innovative (pre-)clinical research that can provide the framework for initiatives to improve our pharmacological understanding of analgesic and sedative drugs used in paediatric severe TBI and ultimately facilitate steps towards evidence-based and precision pharmacotherapy in this vulnerable patient group.

Abstract
OBJECTIVES The devastating effect of traumatic brain injury is exacerbated by an acute secondary neuroinflammatory response, clinically manifest as elevated intracranial pressure due to cerebral edema. The treatment effect of cell-based therapies in the acute post-traumatic brain injury period has not been clinically studied although preclinical data demonstrate that bone marrow-derived mononuclear cell infusion down-regulates the inflammatory response. Our study evaluates whether pediatric traumatic brain injury patients receiving IV autologous bone marrow-derived mononuclear cells within 48 hours of injury experienced a reduction in therapeutic intensity directed toward managing elevated intracranial pressure relative to matched controls. DESIGN The study was a retrospective cohort design comparing pediatric patients in a phase I clinical trial treated with IV autologous bone marrow-derived mononuclear cells (n = 10) to a control group of age- and severity-matched children (n = 19). SETTING The study setting was at Children's Memorial Hermann Hospital, an American College of Surgeons Level 1 Pediatric Trauma Center and teaching hospital for the University of Texas Health Science Center at Houston from 2000 to 2008. PATIENTS Study patients were 5-14 years with postresuscitation Glasgow Coma Scale scores of 5-8. INTERVENTIONS The treatment group received 6 million autologous bone marrow-derived mononuclear cells/kg body weight IV within 48 hours of injury. The control group was treated in an identical fashion, per standard of care, guided by our traumatic brain injury management protocol, derived from American Association of Neurological Surgeons guidelines. MEASUREMENTS AND MAIN RESULTS The primary measure was the Pediatric Intensity Level of Therapy scale used to quantify treatment of elevated intracranial pressure. Secondary measures included the Pediatric Logistic Organ Dysfunction score and days of intracranial pressure monitoring as a surrogate for length of neurointensive care. A repeated-measure mixed model with marginal linear predictions identified a significant reduction in the Pediatric Intensity Level of Therapy score beginning at 24 hours posttreatment through week 1 (p < 0.05). This divergence was also reflected in the Pediatric Logistic Organ Dysfunction score following the first week. The duration of intracranial pressure monitoring was 8.2 ± 1.3 days in the treated group and 15.6 ± 3.5 days (p = 0.03) in the time-matched control group. CONCLUSIONS IV autologous bone marrow-derived mononuclear cell therapy is associated with lower treatment intensity required to manage intracranial pressure, associated severity of organ injury, and duration of neurointensive care following severe traumatic brain injury. This may corroborate preclinical data that autologous bone marrow-derived mononuclear cell therapy attenuates the effects of inflammation in the early post-traumatic brain injury period.

Quantitative analysis of computed tomography images and early detection of cerebral edema for pediatric traumatic brain injury patients: retrospective study. BMC Med 2014; 12:186.

Abstract
BACKGROUND The purpose of this study was to identify whether the distribution of Hounsfield Unit (HU) values across the intracranial area in computed tomography (CT) images can be used as an effective diagnostic tool for determining the severity of cerebral edema in pediatric traumatic brain injury (TBI) patients. METHODS CT images, medical records and radiology reports on 70 pediatric patients were collected. Based on radiology reports and the Marshall classification, the patients were grouped as mild edema patients (n=37) or severe edema patients (n=33). Automated quantitative analysis using unenhanced CT images was applied to eliminate artifacts and identify the difference in HU value distribution across the intracranial area between these groups. RESULTS The proportion of pixels with HU=17 to 24 was highly correlated with the existence of severe cerebral edema (P<0.01). This proportion was also able to differentiate patients who developed delayed cerebral edema from mild TBI patients. A significant difference between deceased patients and surviving patients in terms of the HU distribution came from the proportion of pixels with HU=19 to HU=23 (P<0.01). CONCLUSIONS The proportion of pixels with an HU value of 17 to 24 in the entire cerebral area of a non-enhanced CT image can be an effective basis for evaluating the severity of cerebral edema. Based on this result, we propose a novel approach for the early detection of severe cerebral edema.

Abstract
OBJECT Traumatic brain injury (TBI) is a leading cause of injury, hospitalization, and death among pediatric patients. Admission CT scans play an important role in classifying TBI and directing clinical care, but little is known about the differences in CT findings between pediatric and adult patients. The aim of this study was to determine if radiographic differences exist between adult and pediatric TBI. METHODS The authors retrospectively analyzed TBI registry data from 1206 consecutive patients with nonpenetrating TBI treated at a Level 1 adult and pediatric trauma center over a 30-month period. RESULTS The distribution of sex, race, and Glasgow Coma Scale (GCS) score was not significantly different between the adult and pediatric populations; however, the distribution of CT findings was significantly different. Pediatric patients with TBI were more likely to have skull fractures (OR 3.21, p < 0.01) and epidural hematomas (OR 1.96, p < 0.01). Pediatric TBI was less likely to be associated with contusion, subdural hematoma, subarachnoid hemorrhage, or compression of the basal cisterns (p < 0.05). Rotterdam CT scores were significantly lower in the pediatric population (2.3 vs 2.6, p < 0.001). CONCLUSIONS There are significant differences in the CT findings in pediatric versus adult TBI, despite statistical similarities with regard to clinical severity of injury as measured by the GCS. These differences may be due to anatomical characteristics, the biomechanics of injury, and/or differences in injury mechanisms between pediatric and adult patients. The unique characteristics of pediatric TBI warrant consideration when formulating a clinical trial design or predicting functional outcome using prognostic models developed from adult TBI data.

Abstract
AIM The aim of this study was to review the basic aspects of sleep disturbance in children with traumatic brain injury (TBI). METHOD A search was performed on reports of sleep disturbances in children who had suffered TBI. Adults with TBI were also considered to anticipate the nature and significance of such disturbances in younger patients. Types of reported sleep disturbance were noted and their possible aetiology and management considered. RESULTS Sleep disturbance has consistently been associated with TBI but the literature suggests that this aspect of patient care is often inadequately considered and there has been little research on the subject, especially in relation to children. Excessive daytime sleepiness is often mentioned, less so insomnia and parasomnias, but there is little information about the specific sleep disorders underlying these problems. INTERPRETATION Sleep disorders with potentially important developmental consequences have been neglected in the care of children with TBI. Screening for sleep problems should be routine and followed, if indicated, by a detailed diagnosis of the child's underlying specific sleep disorder, the possible aetiology of which includes neuropathology and potential medical, psychological, or psychiatric comorbidities. Appropriate assessments and modern treatment options are now well defined although generally underutilized. Further well-designed research is needed for which guidelines are available.

Abstract
A number of studies have established a deleterious role for inflammatory molecules and reactive oxygen species (ROS) in the pathology of traumatic brain injury (TBI). Caffeic acid phenethyl ester (CAPE) has been shown to exert both antioxidant and anti-inflammatory effects. The primary objective of the present study was to examine if CAPE could be used to reduce some of the pathological consequences of TBI using rodent models. Male Sprague-Dawley rats and C57BL/6 mice were subjected to controlled cortical impact (CCI) injury. Blood-brain barrier (BBB) integrity was assessed by examining claudin-5 expression and the extravasation of Evans blue dye. The effect of post-injury CAPE administration on neurobehavioral function was assessed using vestibulomotor, motor, and two hippocampus-dependent learning and memory tasks. We report that post-TBI administration of CAPE reduces Evans blue extravasation both in rats and mice. This improvement was associated with preservation of the levels of the tight junction protein claudin-5. CAPE treatment did not improve performance in either vestibulomotor/motor function (tested using beam balance and foot-fault tests), or in learning and memory function (tested using the Morris water maze and associative fear memory tasks). However, animals treated with CAPE were found to have significantly less cortical tissue loss than vehicle-treated controls. These findings suggest that CAPE may provide benefit in the treatment of vascular compromise following central nervous system injury.

Abstract
INTRODUCTION Diffuse brain edema has been described as a major cause of intracranial hypertension (IH) following traumatic brain injury (TBI), and several studies suggest that it may be more frequent in children than in adults. While most cases of IH following TBI are present from the beginning, several studies have described a subgroup of patients with delayed elevations in intracranial pressure (ICP). METHODS Retrospective review of severe pediatric TBI cases admitted to a single institution during a 6-year period. Patients were classified into three groups, based on the temporal evolution of ICP: patients who evolved without IH, patients who had IH at admission and patients with delayed IH. A risk factor analysis was performed to find differences between these groups. RESULTS 31 cases of severe pediatric TBI were analyzed. 13 patients were female and 18 male, with an average age of 8.9 years. 4 patients met the described criteria for delayed IH; the only significant risk factor was presence of edema at the initial brain CT (p = 0.008). 3 additional patients presented clinical deterioration after 48 h and signs of brain edema in the CT, after ICP monitoring had been discontinued. CONCLUSIONS Late-onset IH is a relatively common clinical condition in the pediatric population with severe TBI (present in 13% of the cases in our series), and the presence of a Marshall III CT scan at admission is a significant risk factor for this condition. Pediatric patients may benefit from a more prolonged period of ICP monitoring than adults, and the lack of amelioration of brain edema at follow-up brain CT (even with normal ICP values) may be an indication that more prolonged monitoring is needed.

Abstract
A 6-year-old male was found dead on his stomach with massive reddish vomiting from his mouth and nose. Postmortem cranial CT revealed an epidural haematoma in the left occipital region, but the cause and origin of the haematoma were unclear. An autopsy revealed that the epidural haematoma expanded over the left temporal region and the left side of the occipital region and posterior cranial fossa, and its origin was a laceration in the left transverse sinus induced by diastases in the left lambdoidal and occipitomastoid sutures. A pathohistological examination revealed that one portion of the haematoma was an early-stage hemorrhage, while the other portion extended approximately 1 week after the hemorrhage. Moreover, approximately 1 week elapsed after the laceration of the transverse sinus. Thus, we believe that the primary haematoma was induced by the laceration in the transverse sinus approximately 1 week before death, but the haematoma ceased to enlarge due to hemostasis. However, later, the size of the haematoma rapidly increased again due to rebleeding from the laceration, which led to intracranial hypertension. Consequently, we diagnosed the direct cause of death as choking due to vomit aspiration that resulted from intracranial hypertension induced by a subacute epidural haematoma.
