Abstract
Background Firearm-related injuries (FRI) are an increasing cause of death and injury in children. The etiology for this rise is multifactorial and includes socioeconomic factors. Despite its prevalence and documented increase over COVID-19, there is a paucity of research on disparities and the influence of social determinants of health (SDH) in pediatric FRI. This study aims to explore the epidemiology of this vulnerable population in Atlanta, trends over time and relevant dates such as COVID-19 and a state firearm law, and disparities in clinical outcomes. Methods Retrospective cohort of patients with FRI (0-20 years-old, x̄=9.8, Median = 11) presenting to our hospital EDs from January 2014 to April 2023 (N = 701) and eligible for the Trauma Registry. This period includes two major events, namely the COVID-19 pandemic (March 2020), and passage of state law Constitutional Carry Act (SB 319) (April 2022), allowing for permit-less concealed firearm carry. Single series interrupted time series (ITS) models were run and clinical outcome differences between race and insurance groups were calculated unadjusted and adjusted for confounders using inverse propensity treatment weights (IPTW). The primary outcome was mortality; secondary are admission and discharge. Results Majority of FRI involved patients who were male (76.7%), Black (74.9%), publicly insured (82.6%), ≤12 years-old (61.8%), and injured by unintentional shootings (45.6%) or assault (43.7%). During COVID-19, there was a sustained increase in FRI rate by 0.42 patients per 1,000 trauma visits per month (95% CI 0.02-0.82, p = 0.042); post-SB 319 it was 2.3 patients per 1,000 trauma visits per month (95% CI 0.23-4.31, p = 0.029). Publicly insured patients had 58% lower odds of mortality than privately insured patients (OR 0.42, 95% CI 0.18-0.99, p = 0.047). When controlled for race and mechanism of injury, among other confounding factors, this association was not significant (p = 0.652). Conclusion Pediatric FRI are increasing over time, with disproportionate burdens on Black patients, at our hospitals. Disparities in mortality based on insurance necessitate further study. As social and economic repercussions of COVID-19 are still present, and state firearm law SB 319 is still in effect, assessment of ongoing trends is warranted to inform preventative strategies.

Abstract
BACKGROUND AND OBJECTIVES Global disparity exists in the demographics, pathology, management, and outcomes of surgically treated traumatic brain injury (TBI). However, the factors underlying these differences, including intervention effectiveness, remain unclear. Establishing a more accurate global picture of the burden of TBI represents a challenging task requiring systematic and ongoing data collection of patients with TBI across all management modalities. The objective of this study was to establish a global registry that would enable local service benchmarking against a global standard, identification of unmet need in TBI management, and its evidence-based prioritization in policymaking. METHODS The registry was developed in an iterative consensus-based manner by a panel of neurotrauma professionals. Proposed registry objectives, structure, and data points were established in 2 international multidisciplinary neurotrauma meetings, after which a survey consisting of the same data points was circulated within the global neurotrauma community. The survey results were disseminated in a final meeting to reach a consensus on the most pertinent registry variables. RESULTS A total of 156 professionals from 53 countries, including both high-income countries and low- and middle-income countries, responded to the survey. The final consensus-based registry includes patients with TBI who required neurosurgical admission, a neurosurgical procedure, or a critical care admission. The data set comprised clinically pertinent information on demographics, injury characteristics, imaging, treatments, and short-term outcomes. Based on the consensus, the Global Epidemiology and Outcomes following Traumatic Brain Injury (GEO-TBI) registry was established. CONCLUSION The GEO-TBI registry will enable high-quality data collection, clinical auditing, and research activity, and it is supported by the World Federation of Neurosurgical Societies and the National Institute of Health Research Global Health Program. The GEO-TBI registry ( https://geotbi.org ) is now open for participant site recruitment. Any center involved in TBI management is welcome to join the collaboration to access the registry.

Abstract
BACKGROUND Infectious intracranial aneurysms (IIAs) are a rare sequel of systemic infection and occur most commonly in patients with infective endocarditis (IE). Despite the increasing use of non-invasive screening angiography in patients with IE, the incidence remains low, yielding limited data on the management of IIAs in pediatric populations. We performed a pooled analysis of all published series of pediatric patients with IIAs to study the disease landscape including presentation, management, and outcomes. METHODS Data included in this study were pooled from published literature on IIAs between 1960 and 2023. Abstracts were selected for full review to include only manuscripts reporting at least one case of pediatric IIA (age 0-18 years). RESULTS A total of 145 pediatric patients with 178 IIAs were included. Patients presented with rupture in 68% of cases, of which 36% had intraparenchymal hemorrhage and 39% had subarachnoid hemorrhage. Using multivariate logistic regression, independent predictors of rupture were posterior location (aOR 10, P=0.041) and history of IE (aOR 7.2, P=0.001). Primary medical management was successful in 82% of cases with unruptured aneurysms while, in those with ruptured IIAs, medical management was successful in 26% of cases. The 90-day mortality rate was 28%. Using multivariate logistic regression, ruptured IIAs (aOR 5.4, P<0.01) and failure of medical management (aOR 11.1, P<0.05) were independent predictors of 90-day mortality. CONCLUSION Pediatric IIAs remain a rare complication of systemic or localized CNS infection in the pediatric population. Medical management of unruptured aneurysms is highly successful, while ruptured aneurysms have a remarkably high rate of failure of medical management and should be treated by early surgical or endovascular intervention when feasible.

Abstract
Vertebral artery dissection (VAD) is a common cause of a rare condition, pediatric posterior circulation arterial ischemic stroke (PCAIS). VAD is clinically important due to the risk of multifocal and continuing infarcts from artery-to-artery thromboembolism, with the potential for occlusion of arteries that perfuse the brainstem. Early diagnosis is important, as recurrent stroke is a common effect of VAD in children. Although the relative efficacies of different treatment regimens for VAD in children remain unsettled, early initiation of treatment can mitigate the risk of delayed stroke. Clinical diagnosis of PCAIS may be delayed due to multiple factors, including nonspecific symptoms and the inability of younger patients to express symptoms. In fact, subacute or chronic infarcts are often present at initial imaging. Although the most common cause of isolated PCAIS is VAD, imaging of the cervical arteries has been historically underused in this setting. Cervical vascular imaging (MR angiography, CT angiography, and digital subtraction angiography) for VAD must be optimized to detect the sometimes subtle findings, which may be identified at initial or follow-up imaging. Osseous variants of the craniocervical junction and upper cervical spine and other extrinsic lesions that may directly injure the vertebral arteries or lead to altered biomechanics have been implicated in some cases. The authors review characteristic imaging features and optimized imaging of VAD and associated PCAIS and related clinical considerations. Identification of VAD has important implications for evaluation, treatment, and imaging follow-up, as this condition may result in progressive arteriopathy and recurrent stroke. © RSNA, 2023 Supplemental material is available for this article.

Abstract
Blood based traumatic brain injury (TBI) biomarkers offer additional diagnostic, therapeutic, and prognostic utility. While adult studies are robust, the pediatric population is less well studied. We sought to determine whether plasma osteopontin (OPN) and S100B alone or in combination predict mortality, head Computed tomography (CT) findings, as well as 6-month functional outcomes after TBI in children. This is a prospective, observational study between March 2017 and June 2021 at a tertiary pediatric hospital. The sample included children with a diagnosed head injury of any severity admitted to the Emergency Department. Control patients sustained trauma-related injuries and no known head trauma. Serial blood samples were collected at admission, as well as at 24, 48, and 72 h. Patient demographics, acute clinical symptoms, head CT, and 6-month follow-up using the Glasgow outcome scale, extended for pediatrics (GOSE-Peds), were also obtained. The cohort included 460 children (ages 0 to 21 years) and reflected the race and sex distribution of the population served. Linear mixed effect models and logistic regressions were utilized to evaluate the trajectory of biomarkers over time and predictors of dichotomous outcomes. Both OPN and S100B correlated with injury severity based on GCS. S100B and OPN showed lower AUC values (0.59) in predicting positive head CT. S100B had the largest AUC (0.87) in predicting mortality, as well as 6-month outcomes (0.85). The combination of the two biomarkers did not add meaningfully to the model. Our findings continue to support the utility of OPN as a marker of injury severity in this population. Our findings also show the importance of S100B in predicting mortality and 6-month functional outcomes. Continued work is needed to examine the influence of age-dependent neurodevelopment on TBI biomarker profiles in children.

Abstract
Background The epidemiology of traumatic brain injury (TBI) is unclear - it is estimated to affect 27-69 million individuals yearly with the bulk of the TBI burden in low-to-middle income countries (LMICs). Research has highlighted significant between-hospital variability in TBI outcomes following emergency surgery, but the overall incidence and epidemiology of TBI remains unclear. To address this need, we established the Global Epidemiology and Outcomes following Traumatic Brain Injury (GEO-TBI) registry, enabling recording of all TBI cases requiring admission irrespective of surgical treatment. Objective The GEO-TBI: Incidence study aims to describe TBI epidemiology and outcomes according to development indices, and to highlight best practices to facilitate further comparative research. Design Multi-centre, international, registry-based, prospective cohort study. Subjects Any unit managing TBI and participating in the GEO-TBI registry will be eligible to join the study. Each unit will select a 90-day study period. All TBI patients meeting the registry inclusion criteria (neurosurgical/ICU admission or neurosurgical operation) during the selected study period will be included in the GEO-TBI: Incidence. Methods All units will form a study team, that will gain local approval, identify eligible patients and input data. Data will be collected via the secure registry platform and validated after collection. Identifiers may be collected if required for local utility in accordance with the GEO-TBI protocol. Data Data related to initial presentation, interventions and short-term outcomes will be collected in line with the GEO-TBI core dataset, developed following consensus from an iterative survey and feedback process. Patient demographics, injury details, timing and nature of interventions and post-injury care will be collected alongside associated complications. The primary outcome measures for the study will be the Glasgow Outcome at Discharge Scale (GODS) and 14-day mortality. Secondary outcome measures will be mortality and extended Glasgow Outcome Scale (GOSE) at the most recent follow-up timepoint.

Abstract
Introduction Infant type hemispheric gliomas are a rare tumor with unique molecular characteristics. In many cases these harbor mutations in receptor tyrosine kinase pathways and respond to targeted therapy. Here we describe the case of an infant with this type of tumor with a novel ATIC-ALK fusion that has responded dramatically to the ALK inhibitor lorlatinib, despite being refractory to standard chemotherapy. Case description The infant was initially treated with standard chemotherapy and found to have an ATIC-ALK fusion. When surveillance imaging revealed progressive disease, the patient was switched to the ALK-inhibitor lorlatinib at 47 mg/m2/day. The patient demonstrated a significant clinical and radiographic response to the ALK inhibitor lorlatinib after just 3 months of treatment and a near complete response by 6 months of therapy. Conclusion The ALK inhibitor lorlatinib is an effective targeted therapy in infant type hemispheric glioma patients harboring ATIC-ALK fusion.

Abstract
BACKGROUND Subdural to peritoneal shunt (SPS) placement is an established treatment option for chronic subdural hematoma (SDH) in the pediatric population. Practice patterns vary between institutions, with some advocating shunt removal while others leave the SPS in place after SDH resolution. There remain a paucity of data to document the safety and outcomes after removal of SPS. OBJECTIVE To support the safety and efficacy of SPS placement and subsequent removal for chronic SDH in children younger than 2 years. METHODS A total of 26 patients younger than 2 years underwent SPS removal procedures over a 5-year period from 2015 to 2019 at a single institution. Patient characteristics, hospital course, and outcomes were prospectively recorded in the hospital electronic medical record. Attention was given to change in head circumference, size of subdural collection, need for reoperation, or complications because of shunt removal. RESULTS Patients who underwent SPS placement presented with macrocephaly, signs and symptoms of increased intracranial pressure, and radiographical evidence of subdural collections. The most common etiology of chronic SDH was nonaccidental head trauma (18 of 26 patients). SDS was kept in place for an average of 10 months. Resolution of SDH was demonstrated on imaging for all 26 patients. One patient did require reinsertion of SPS 2 weeks after SPS removal. CONCLUSION Removal of SPS remains controversial, and careful consideration of patient, family, and provider preferences and potential risks associated with SPS removal must be taken into consideration.

Abstract
Pleuropulmonary blastoma (PPB) is a rare pediatric tumor of the pleura and pulmonary mesenchyme, associated with pathogenic germline DICER1 mutations. Although the most common site of metastasis is the central nervous system (CNS), patients with CNS metastasis have dismal outcome. We report a case of a patient presenting with type II PPB and intracranial and bone metastases. We describe a multimodal therapy approach and highlight the use of intraventricular topotecan for isolated CNS recurrence. In addition, a new pathogenic germline mutation heterozygous for the c.1234delT of DICER1 was identified. Patient remains in remission 3 years after recurrence.

Abstract
BACKGROUND The mainstay of treatment for cerebellar pilocytic astrocytomas in the pediatric population is surgery. The use of intraoperative magnetic resonance imaging (iMRI) as a surgical adjunct may lower the likelihood of reoperation. Studies have examined iMRI in heterogenous tumor populations, but few have looked at single pathologies. OBJECTIVE To compare iMRI vs non-iMRI for hemispheric cerebellar pilocystic astrocytomas, specifically looking at revision surgeries and residual disease in follow-up. METHODS Retrospective review of medical records for 60 sequential patients with cerebellar hemispheric pilocytic astrocytoma at a single institution was conducted. Thirty-two patients with cerebellar pilocytic astrocytoma underwent surgery without iMRI, whereas 28 patients underwent surgical resection with iMRI. All patients had at least 3-year follow-up. RESULTS There were no significant differences between the patient populations in age, tumor size, or need for cerebrospinal fluid diversion between groups. Operative time was shorter without iMRI (without iMRI 4.4 ± 1.3 hours, iMRI 6.1 ± 1.5, P = .0001). There was no significant difference in the patients who had repeat surgery within 30 days (9% without iMRI, 0% iMRI, P = .25), residual disease at 3 months (19% without iMRI, 14% iMRI, P = .78), or underwent a second resection beyond 30 days (9% without iMRI, 4% iMRI, P = .61). There were more total reoperations in the group without iMRI, although this did not reach significance (19% vs 4%, P = .11). CONCLUSION For hemispheric cerebellar pilocytic astrocytomas, iMRI tended to leave less residual and fewer reoperations; however, neither of these outcomes achieved statistical significance leaving utilization to be determined by the surgeon.

Abstract
This study sought to evaluate the candidacy of plasma osteopontin (OPN) as a biomarker of COVID-19 severity and multisystem inflammatory condition in children (MIS-C) in children. A retrospective analysis of 26 children (0-21 years of age) admitted to Children's Healthcare of Atlanta with a diagnosis of COVID-19 between March 17 and May 26, 2020 was undertaken. The patients were classified into three categories based on COVID-19 severity levels: asymptomatic or minimally symptomatic (control population, admitted for other non-COVID-19 conditions), mild/moderate, and severe COVID-19. A fourth category of children met the Centers for Disease Control and Prevention's case definition for MIS-C. Residual blood samples were analyzed for OPN, a marker of inflammation using commercial ELISA kits (R&D), and results were correlated with clinical data. This study demonstrates that OPN levels are significantly elevated in children hospitalized with moderate and severe COVID-19 and MIS-C compared to OPN levels in mild/asymptomatic children. Further, OPN differentiated among clinical levels of severity in COVID-19, while other inflammatory markers including maximum erythrocyte sedimentation rate, C-reactive protein and ferritin, minimum lymphocyte and platelet counts, soluble interleukin-2R, and interleukin-6 did not. We conclude OPN is a potential biomarker of COVID-19 severity and MIS-C in children that may have future clinical utility. The specificity and positive predictive value of this marker for COVID-19 and MIS-C are areas for future larger prospective research studies.

Abstract
BACKGROUND Magnetic resonance imaging (MRI)-guided laser interstitial thermal therapy (MRgLITT) has been used successfully to treat epileptogenic cortical cerebral cavernous malformations (CCM). It is unclear whether MRgLITT would be as feasible or safe for deep CCMs. OBJECTIVE To describe our experience with MRgLITT for symptomatic deep CCMs. METHODS Patients' records were reviewed retrospectively. MRgLITT was carried out using a commercially available system in an interventional MRI suite with efforts to protect adjacent brain structures. Immediate postoperative imaging was used to judge ablation adequacy. Delayed postoperative MRI was used to measure lesion volume changes during follow-up. RESULTS Four patients with CCM in the thalamus, putamen, midbrain, or subthalamus presented with persistent and disabling neurological symptoms. A total of 2 patients presented with disabling headaches and sensory disturbances and 2 with recurrent symptomatic hemorrhages, of which 1 had familial CCM. Patients were considered by vascular neurosurgeons to be poor candidates for open surgery or had refused it. Multiple trajectories were used in most cases. Adverse events included device malfunction with leakage of saline causing transient mass effect in one patient, and asymptomatic tract hemorrhage in another. One patient suffered an expected mild but persistent exacerbation of baseline deficits. All patients showed improvement from a previously aggressive clinical course with lesion volume decreased by 20% to 73% in follow-up. CONCLUSION MRgLITT is feasible in the treatment of symptomatic deep CCM but may carry a high risk of complications without the benefit of definitive resection. We recommend cautious patient selection, low laser power settings, and conservative temperature monitoring in surrounding brain parenchyma.

Abstract
BACKGROUND It is expected that the incidence of cerebrospinal fluid (CSF) shunt malfunctions would remain unchanged during the shelter-in-place period related to the COVID-19 pandemic. OBJECTIVE To examine the number of shunt surgeries performed in a single institution during this time interval in comparison to equivalent periods in past years. METHODS The numbers of elective and emergent/urgent shunt surgeries performed at a single institution were queried for a 28-d period starting on the third Monday of March, between years 2015 and 2020. These were further stratified by how they presented as well as the type of surgery performed. RESULTS During the 28-d period of interest, in the years between 2015 and 2020, there was a steady increase in the number of shunt surgeries performed, with a maximum of 64 shunt surgeries performed in 2019. Of these, approximately 50% presented in urgent fashion in any given year. In the 4-wk period starting March 16, 2020, a total of 32 shunt surgeries were performed, with 15 of those cases presenting from the outpatient setting in emergent/urgent fashion. For the surgeries performed, there was a statistically significant decrease in the number of revision shunt surgeries performed. CONCLUSION During the 2020 COVID-19 pandemic, there was an unexpected decrease in the number of shunt surgeries performed, and particularly in the number of revision surgeries performed. This suggests that an environmental factor related to the pandemic is altering the presentation rate of shunt malfunctions.

Abstract
OBJECTIVE The management of hydrocephalus resulting from intraventricular hemorrhage related to extreme prematurity remains demanding. Given the complexities of controlling hydrocephalus in this population, less commonly used procedures may be required. The authors examined the utility of ventriculogallbladder (VGB) shunts in a series of such children. METHODS The authors retrospectively reviewed the medical records of all children who underwent surgery for hydrocephalus in the period from 2011 through 2019 at Children's Healthcare of Atlanta. Six patients who underwent VGB shunt placement were identified among a larger cohort of 609 patients who had either a new shunt or a newly changed distal terminus site. The authors present an analysis of this series, including a case of laparoscopy-assisted distal VGB shunt revision. RESULTS The mean age at initial shunt placement was 5.1 months (range 3.0-9.4 months), with patients undergoing a mean of 11.8 shunt procedures (range 5-17) prior to the initial VGB shunt placement at a mean age of 5.3 years (range 7.9 months-12.8 years). All 6 patients with VGB shunt placement had hydrocephalus related to extreme prematurity (gestational age < 28 weeks). At the time of VGB shunt placement, all had complex medical and surgical histories, including poor venous access due to congenital or iatrogenic thrombosis or thrombophlebitis and a peritoneum hostile to distal shunt placement related to severe necrotizing enterocolitis. VGB complications included 1 case of shunt infection, identified at postoperative day 6, and 2 cases of distal shunt failure due to retraction of the distal end of the VGB shunt. In all, there were 3 conversions back to ventriculoperitoneal or ventriculoatrial shunts due to the 2 previously mentioned complications, plus 1 patient who outgrew their initial VGB shunt. Three of 6 patients remain with a VGB shunt, including 1 who underwent laparoscopy-assisted distal shunt revision 110.5 months after initial VGB shunt insertion. CONCLUSIONS Placement of VGB shunts should be considered in the armamentarium of procedures that may be used in the particularly difficult cohort of children with hydrocephalus related to extreme prematurity. VGB shunts show utility as both a definitive treatment and as a "bridge" procedure until the patient is larger and comorbid abdominal and/or vascular issues have resolved sufficiently to allow conversion back to ventriculoperitoneal or ventriculoatrial shunts, if needed.

Abstract
OBJECTIVE To examine levels of plasma osteopontin (OPN), a recently described neuroinflammatory biomarker, in children with abusive head trauma (AHT) compared with children with other types of traumatic brain injury (TBI). STUDY DESIGN The study cohort comprised children aged <4 years diagnosed with TBI and seen in the intensive care unit in a tertiary children's hospital. Patients were classified as having confirmed or suspected AHT or TBI by other mechanisms (eg, motor vehicle accidents), as identified by a Child Protection Team clinician. Serial blood samples were collected at admission and at 24, 48, and 72 hours after admission. Levels of OPN were compared across groups. RESULTS Of 77 patients identified, 24 had confirmed AHT, 12 had suspected AHT, and 41 had TBI. There were no differences in the Glasgow Coma Scale score between the patients with confirmed AHT and those with suspected AHT and those with TBI (median score, 4.5 vs 4 and 7; P = .39). At admission to the emergency department, OPN levels were significantly higher in children with confirmed AHT compared with the other 2 groups (mean confirmed AHT, 471.5 ng/mL; median suspected AHT, 322.3 ng/mL; mean TBI, 278.0 ng/mL; P = .03). Furthermore, the adjusted mean trajectory levels of OPN were significantly higher in the confirmed AHT group compared with the other 2 groups across all subsequent time points (P = <.01). CONCLUSIONS OPN is significantly elevated in children with confirmed AHT compared with those with suspected AHT and those with other types of TBI. OPN expression may help identify children with suspected AHT to aid resource stratification and triage of appropriate interventions for children who are potential victims of abuse.

Abstract
Penetrating traumatic brain injury (TBI) is uncommon in infancy. The consequences may be devastating, especially when the injury is extensive and affects eloquent areas of the brain. There is the potential for neuropsychological dysfunction that may impact the individual's development and well-being into adulthood. In the context of early brain injury, the developing brain is both remarkably resilient and vulnerable. The present case study describes a patient who experienced a penetrating TBI at 9 days of age, subsequently developed intractable seizures, and underwent left hemispherectomy. Neuropsychological testing at ages 5, 10, 11, and 19 years are presented alongside fMRI and Wada testing. While the patient initially developed cognitive functions in the low-average range by age 5, scores on neuropsychological assessments began to decrease thereafter. This case is discussed with attention to vulnerability and plasticity theories. It highlights the ability of the brain to reorganize and allow the development of functions that would normally be sub-served by damaged areas and the limits of plasticity. Further, this case illustrates the vulnerability of the early brain to insult, the potential to grow into deficits, and the need to consider a variety of factors when predicting outcomes for cases of pediatric brain injury.

Abstract
Traumatic brain injury (TBI) is the leading cause of death in children and adolescents in developed countries, but there are no blood-based biomarkers to support the diagnosis or prognosis of pediatric TBI to-date. Here we report that the plasma levels of osteopontin (OPN), a phosphoprotein chiefly secreted by macrophages and/or activated microglia, may contribute to this goal. In animal models of TBI, while OPN, fibrillary acidic protein (GFAP), and matrix metalloproteinase 9 (MMP-9) were all readily induced by controlled cortical impact in the brains of one-month-old mice, only OPN and GFAP ascended in the blood in correlation with high neurological severity scores (NSS). In children with TBI (three to nine years of age, n = 66), the plasma levels of OPN, but not GFAP, correlated with severe TBI (Glasgow Coma Score ≤ 8) and intracranial lesions at emergency department. In addition, the plasma OPN levels in severe pediatric TBI patients continued to ascend for 72 h and correlated with mortality and the days requiring ventilator or intensive care unit support, whereas the plasma GFAP levels lacked these properties. Together, these results suggest that plasma OPN outperforms GFAP and may be a neuroinflammation-based diagnostic and prognostic biomarker in pediatric TBI.

Abstract
OBJECTIVE The malfunction rates of and trends in various cerebrospinal fluid (CSF) shunt designs have been widely studied, but one area that has received little attention is the comparison of the peritoneal distal slit valve (DSV) shunt to other conventional valve (CV) type shunts. The literature that does exist comes from older case series that provide only indirect comparisons, and the conclusions are mixed. Here, the authors provide a direct comparison of the overall survival and failure trends of DSV shunts to those of other valve type shunts. METHODS Three hundred seventy-two new CSF shunts were placed in pediatric patients at the authors' institution between January 2011 and December 2015. Only ventriculoperitoneal (VP) shunts were eligible for study inclusion. Ventriculoatrial, lumboperitoneal, cystoperitoneal, subdural-peritoneal, and spinal shunts were all excluded. Rates and patterns of shunt malfunction were compared, and survival curves were generated. Patterns of failure were categorized as proximal failure, distal failure, simultaneous proximal and distal (proximal+distal) failure, removal for infection, externalization for abdominal pseudocyst, and addition of a ventricular catheter for loculated hydrocephalus. RESULTS A total of 232 VP shunts were included in the final analysis, 115 DSV shunts and 117 CV shunts. There was no difference in the overall failure rate or time to failure between the two groups, and the follow-up period was statistically similar between the groups. The DSV group had a failure rate of 54% and a mean time to failure of 17.8 months. The CV group had a failure rate of 50% (p = 0.50) and a mean time to failure of 18.5 months (p = 0.56). The overall shunt survival curves for these two groups were similar; however, the location of failure was significantly different between the two groups. Shunts with DSVs had proportionately more distal failures than the CV group (34% vs 14%, respectively, p = 0.009). DSV shunts were also found to have proximal+distal catheter occlusions more frequently than CV shunts (23% vs 5%, respectively, p = 0.005). CV shunts were found to have significantly more proximal failures than the DSV shunts (53% vs 27%, p = 0.028). However, the only failure type that carried a statistically significant adjusted hazard ratio in a multivariate analysis was proximal+distal catheter obstruction (CV vs DSV shunt: HR 0.21, 95% CI 0.05-0.81). CONCLUSIONS There appears to be a difference in the location of catheter obstruction leading to the malfunction of shunts with DSVs compared to shunts with CVs; however, overall shunt survival is similar between the two. These failure types are also affected by other factors such etiology of hydrocephalus and endoscope use. The implications of these findings are unclear, and this topic warrants further investigation.

Abstract
OBJECTIVE Evidence shows mixed efficacy of applying guidelines for the treatment of traumatic brain injury (TBI) in children. A multidisciplinary team at a children's health system standardized intensive care unit-based TBI care using guidelines and best practices. The authors sought to investigate the impact of guideline implementation on outcomes. METHODS A multidisciplinary group developed a TBI care protocol based on published TBI treatment guidelines and consensus, which was implemented in March 2011. The authors retrospectively compared preimplementation outcomes (May 2009 to March 2011) and postimplementation outcomes (April 2011 to March 2014) among patients < 18 years of age admitted with severe TBI (Glasgow Coma Scale score ≤ 8) and potential survivability who underwent intracranial pressure (ICP) monitoring. Measures included mortality, hospital length of stay (LOS), ventilator LOS, critical ICP elevation time (percentage or total time that ICP was > 40 mm Hg), and survivor functionality at discharge (measured by the WeeFIM score). Data were analyzed using Student t-tests. RESULTS A total of 71 and 121 patients were included pre- and postimplementation, respectively. Mortality (32% vs 19%; p < 0.001) and length of critical ICP elevation (> 20 mm Hg; 26.3% vs 15%; p = 0.001) decreased after protocol implementation. WeeFIM discharge scores were not statistically different (57.6 vs 58.9; p = 0.9). Hospital LOS (median 19.6 days; p = 0.68) and ventilator LOS (median 10 days; p = 0.24) were unchanged. CONCLUSIONS A multidisciplinary effort to develop, disseminate, and implement an evidence-based TBI treatment protocol at a children's hospital was associated with improved outcomes, including survival and reduced time of ICP elevation. This type of ICP-based protocol can serve as a guide for other institutions looking to reduce practice disparity in the treatment of severe TBI.

Abstract
BACKGROUND Severe cervical kyphosis in the setting of neurofibromatosis type 1 (NF1) is a rare manifestation of the disease in the pediatric population. Dystrophic and immature bone complicate the placement of hardware necessary for surgical correction of alignment and a review of the literature yields 4 cases of pediatric patients with NF1 requiring surgical intervention in which the youngest patient was 10 yr old. OBJECTIVE To report the case of an 11-mo-old female with NF1 who presented with a plexiform cervical neurofibroma and focal cervical kyphosis. A comprehensive review of the literature and a detailed description of nonsurgical and surgical management for this patient population is described. METHODS A literature review was completed for article reviewing management of pediatric patients with cervical spine injuries and NF1. The patient's chart was reviewed and the patient was followed for a year to provide adequate follow-up. Institutional Review Board (IRB)/ethics committee approval and patient consent were neither required nor sought for this study. RESULTS The literature was reviewed, summarized, and utilized for operative planning and postoperative management. Postoperative imaging and 1-yr follow-up imaging showed anterior construct and lateral mass fusion, restoration of cervical alignment, and no neurological deficits. CONCLUSION This is the youngest reported patient to have surgical cervical kyphosis correction in the setting of NF1. A review of the literature helped develop a long-term plan and shape a novel same-day front-back-front approach to restore alignment that will be of use to teams managing these complex patients in the future.

Abstract
OBJECTIVE To determine the relation between sleep quantity and sleep disturbances on symptoms and neurocognitive ability during the acute phase (<7d) and after sports-related concussion (SRC; >21d). DESIGN Prospective inception cohort study. SETTING General community setting of regional middle and high schools. PARTICIPANTS A sample (N=971) including youth athletes with SRC (n=528) and controls (n=443) (age, 10-18y). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Athletes completed the Immediate Post-Concussion Assessment and Cognitive Testing battery. Partial correlation analyses and independent t tests were conducted to assess sleep quantity the night before testing. Multivariate analysis of covariance was used to assess sleep disturbances and their interaction with age. RESULTS Less sleep quantity was correlated with greater report of cognitive (P=.001) and neuropsychological (P=.024) symptoms specific to prolonged recovery from SRC. Sleep disturbances significantly affect each migraine, cognitive, and neuropsychological symptoms (P<.001). A significant interaction was found between sleep disturbances and age (P=.04) at >21 days post-SRC. CONCLUSIONS Findings emphasize that the continued presence of low sleep quantity and sleep disturbances in youth athletes with SRC should be a specific indicator to health professionals that these athletes are at an increased risk of protracted recovery. Further research should identify additional factors that may interact with sleep to increase the risk of protracted recovery.

Abstract
OBJECTIVE Jackson-Pratt drains (JPDs) are commonly employed in pediatric craniofacial reconstructive surgery (CRFS) to reduce postoperative wound complications, but their risk profile remains unknown. Perioperative blood loss and volume shifts are major risks of CFRS. The goal of this study was to evaluate the risks of JPD usage in CFRS, particularly with regard to perioperative blood loss, hyponatremia, intensive care unit (ICU) length of stay, and postoperative wound complications. METHODS The authors performed a retrospective review of data obtained in pediatric patients who underwent CFRS at a single institution, as performed by multiple surgeons between January 2010 and December 2014. Data were gathered from patients who did and did not receive JPDs at the time of surgery. Outcome measures were compared between the JPD and no-JPD groups. RESULTS The overall population 179 pediatric patients: 128 who received JPDs and 51 who did not. In their analysis, the authors found no significant differences in baseline patient characteristics between the two groups. The average JPD output over the first 48 hours was 222 ± 142 ml. When examining the immediate preoperative to immediate postoperative time period, no significant differences were noted between the groups with regard to the need for blood transfusion or changes in hemoglobin, hematocrit, or serum sodium levels. These differences were also not significant when examining the 48-hour postoperative period. Finally, no significant differences in hospital length of stay, ICU length of stay, or emergency department visits at 60 days were noted between the two groups. CONCLUSIONS In this retrospective study, the use of JPDs in pediatric CFRS was not associated with an increased risk of serious perioperative complications, although the benefits of this practice remain unclear.

Abstract
OBJECTIVE Past studies have suggested correlations between abusive head trauma and concurrent cervical spine (c-spine) injury. Accordingly, c-spine MRI (cMRI) has been increasingly used in radiographic assessments. This study aimed to determine trends in cMRI use and treatment, and outcomes related to c-spine injury in children with nonaccidental trauma (NAT). METHODS A total of 503 patients with NAT who were treated between 2009 and 2014 at a single pediatric health care system were identified from a prospectively maintained database. Additional data on selected clinical events were retrospectively collected from electronic medical records. In 2012, a clinical pathway on cMRI usage for patients with NAT was implemented. The present study compared cMRI use and clinical outcomes between the prepathway (2009-2011) and postpathway (2012-2014) periods. RESULTS There were 249 patients in the prepathway and 254 in the postpathway groups. Incidences of cranial injury and Injury Severity Scores were not significantly different between the 2 groups. More patients underwent cMRI in the years after clinical pathway implementation than before (2.8% vs 33.1%, p < 0.0001). There was also a significant increase in cervical collar usage from 16.5% to 27.6% (p = 0.004), and more patients were discharged home with cervical collar immobilization. Surgical stabilization occurred in a single case in the postpathway group. CONCLUSIONS Heightened awareness of potential c-spine injury in this population increased the use of cMRI and cervical collar immobilization over a 6-year period. However, severe c-spine injury remains rare, and increased use of cMRI might not affect outcomes markedly.

Abstract
OBJECTIVE To evaluate the potential impact of a concussion management education program on community-practicing pediatricians. STUDY DESIGN We prospectively surveyed 210 pediatricians before and 18 months after participation in an evidence-based, concussion education program. Pediatricians were part of a network of 38 clinically integrated practices in metro-Atlanta. Participation was mandatory for at least 1 pediatrician in each practice. We assessed pediatricians' self-reported concussion knowledge, use of guidelines, and comfort level, as well as self-reported referral patterns for computed tomography (CT) and/or emergency department (ED) evaluation of children who sustained concussion. RESULTS Based on responses from 120 pediatricians participating in the 2 surveys and intervention (response rate, 57.1%), the program had significant positive effects from pre- to postintervention on knowledge of concussions (-0.26 to 0.56 on -3 to +1 scale; P < .001), guideline use (0.73-.06 on 0-6 scale; P < .01), and comfort level in managing concussions (3.76-4.16 on 1-5 scale; P < .01). Posteducation, pediatricians were significantly less likely to self-report referral for CT (1.64-1.07; P < .001) and CT/ED (4.73-3.97; P < .01), but not ED referral alone (3.07-3.09; P = ns). CONCLUSIONS Adoption of a multifaceted, evidence-based, education program translated into a positive modification of self-reported practice behavior for youth concussion case management. Given the surging demand for community-based youth concussion care, this program can serve as a model for improving the quality of pediatric concussion management.

Abstract
OBJECT Of the 1.7 million traumatic brain injuries (TBIs) in the US, a third occur in patients under 14 years of age. The rate of posttraumatic epilepsy (PTE) may be as high as 19% after severe pediatric TBI, but the risk for seizures after mild TBI is unknown. Although the rate of seizures after mild TBI may be low, current practice is often driven by high clinical concern for posttraumatic seizures. In this study, the authors evaluated electroencephalography (EEG) results and antiepileptic drug (AED) use in a large cohort of children with mild TBI to estimate the incidence of posttraumatic seizures in this population. METHODS Patients presenting to Children's Hospital of Atlanta for mild TBI from 2010 to 2013 were evaluated. Five thousand one hundred forty-eight patients with mild TBI were studied and divided into 3 groups: 4168 who were discharged from the emergency department, 868 who were admitted without neurosurgical intervention, and 112 who underwent neurosurgical procedures (craniotomy for hematoma evacuation or elevation of depressed skull fractures) but were discharged without an extended stay. Demographic information, CT characteristics, EEG reports, and prescriptions for AEDs were analyzed. Long-term follow-up was sought for all patients who underwent EEG. Correlation between EEG result and AED use was also evaluated. RESULTS All patients underwent head CT, and admitted patients were more likely to have an abnormal study (p < 0.0001). EEG evaluations were performed for less than 1.0% of patients in all 3 categories, without significant differences between groups (p = 0.97). Clinicians prescribed AEDs in less than 2.0% of patients for all groups, without significant differences between groups (p = 0.094). Even fewer children continue to see a neurologist for long-term seizure management. The EEG result had good negative predictive value, but only an abnormal EEG reading that was diagnostic of seizures correlated significantly with AED prescription (p = 0.04). CONCLUSIONS EEG utilization and AED prescription was low in all 3 groups, indicating that seizures following mild TBI are likely rare events. EEG has good negative predictive value for patients who did not receive AEDs, but has poorer positive predictive value for AED use.

Abstract
BACKGROUND To date, few studies have delineated clear sex-based differences in symptom resolution after a sports-related concussion (SRC), and equivocal results have been identified in sex-based differences on baseline assessments. PURPOSE To assess whether female athletes displayed prolonged recovery and more symptoms at baseline and after an SRC compared with male athletes. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The current study assessed 135 male and 41 female athletes (10-18 years old) who participated in high-impact sports in metropolitan Atlanta middle and high schools. All athletes completed a baseline assessment and at least 1 postconcussion assessment from the Immediate Post-Concussion Assessment and Cognitive Testing battery. Longitudinal hierarchical linear modeling was employed to examine individual-level variables and their associations with adolescents' rates of recovery in concussive symptoms after controlling for age and number of prior concussions. RESULTS Aggregate symptoms were rated as higher in female athletes compared with male athletes at baseline (mean ± SD: females, 13.49 ± 11.20; males, 4.88 ± 8.74; F(1,175) = 10.59, P < .001) and immediately after a concussion (females: 16.75 ± 18.08; males: 10.58 ± 14.21; F(1,175) = 3.99, P = .05). There were no group differences in the slope of recovery between male and female athletes, indicating generally similar trajectories of change for both groups. Post hoc analyses revealed higher baseline levels of migraine and neuropsychological symptoms in female athletes. CONCLUSION Although female athletes in the current study reported increased symptoms, identical recovery patterns were observed in both sexes, suggesting that sex-based differences in concussion recovery are better explained by increased symptom frequency among female athletes when compared with their male counterparts.

Abstract
Background Given the popularity of dogs in the United States, children with dog bite injuries represent a significant health concern. While dog bite injury in any area of the body can lead to significant morbidity and potential mortality, dog bite injury to the head tends to occur in younger children and leads to more significant pathology. Methods This study presents data obtained from retrospective analysis of a trauma database from a single, urban pediatric hospital system. Data were gathered over more than eight years and includes 236 patients. We examined patient demographics, dog breed involved, hospital course and treatment, infection rate, antibiotic use, and disposition. Results Of the 236 total patients, 174 patients had head involvement with the injury. The dog involved tended to be an animal owned by a family member or family friend. Patients who had head involvement tended to be younger than those without head involvement. Head injury correlated with a significant increase in the number of surgeries required. The two deaths were exclusively in children under three months of age who had head involvement. Patients given antibiotic prophylaxis with amoxicillin/clavulanic acid were associated with a lower rate of post-injury infection than patients on other forms of antibiotic prophylaxis, and patients treated without antibiotic prophylaxis had a lower infection than those treated with prophylactic antibiotics. Conclusions Dog bites in children represent a significant, preventable cause of morbidity and mortality. Our data suggest that young children are especially vulnerable and dog–child interactions should be monitored closely, even when the dog is familiar to the child.

Abstract
In environments in which opioids are increasingly abused for recreation, children are becoming more at risk for both accidental and nonaccidental intoxication. In toxic doses, opioids can cause potentially lethal acute leukoencephalopathy, which has a predilection for the cerebellum in young children. The authors present the case of a 2-year-old girl who suffered an accidental opioid overdose, presenting with altered mental status requiring cardiorespiratory support. She required emergency posterior fossa decompression, partial cerebellectomy, and CSF drainage due to cerebellar edema compressing the fourth ventricle. To the authors' knowledge, this is the first report of surgical decompression used to treat cerebellar edema associated with opioid overdose in a child.

Abstract
Cognitive regression is a well-described presentation of vein of Galen aneurysmal malformations (VGAMs) in childhood. However, it remains unclear whether successful treatment of the malformation can reverse cognitive regression. Here, the authors present the case of a 5-year-old girl with a VGAM that was treated with staged endovascular embolization procedures. Comprehensive neurocognitive assessments were completed before intervention and approximately 6 years after initial presentation. There were significant age-matched improvements in this child's neurocognitive profile over this period. The authors believe that timely and successful treatment of VGAM in children may not only stabilize the associated cognitive deterioration but, in some cases, may ameliorate these deficits. Details of this case and a discussion of neurocognitive deficits related to VGAM are presented.

Abstract
OBJECT Nonoperative blunt head trauma is a common reason for admission in a pediatric hospital. Adverse events, such as growing skull fracture, are rare, and the incidence of such morbidity is not known. As a result, optimal follow-up care is not clear. METHODS Patients admitted after minor blunt head trauma between May 1, 2009, and April 30, 2013, were identified at a single institution. Demographic, socioeconomic, and clinical characteristics were retrieved from administrative and outpatient databases. Clinical events within the 180-day period following discharge were reviewed and analyzed. These events included emergency department (ED) visits, need for surgical procedures, clinic visits, and surveillance imaging utilization. Associations among these clinical events and potential contributing factors were analyzed using appropriate statistical methods. RESULTS There were 937 admissions for minor blunt head trauma in the 4-year period. Patients who required surgical interventions during the index admission were excluded. The average age of the admitted patients was 5.53 years, and the average length of stay was 1.7 days; 15.7% of patients were admitted for concussion symptoms with negative imaging findings, and 26.4% of patients suffered a skull fracture without intracranial injury. Patients presented with subdural, subarachnoid, or intraventricular hemorrhage in 11.6%, 9.19%, and 0.53% of cases, respectively. After discharge, 672 patients returned for at least 1 follow-up clinic visit (71.7%), and surveillance imaging was obtained at the time of the visit in 343 instances. The number of adverse events was small and consisted of 34 ED visits and 3 surgeries. Some of the ED visits could have been prevented with better discharge instructions, but none of the surgery was preventable. Furthermore, the pattern of postinjury surveillance imaging utilization correlated with physician identity but not with injury severity. Because the number of adverse events was small, surveillance imaging could not be shown to positively influence outcomes. CONCLUSIONS Adverse events after nonoperative mild traumatic injury are rare. The routine use of postinjury surveillance imaging remains controversial, but these data suggest that such imaging does not effectively identify those who require operative intervention.

Abstract
OBJECT The rate of readmission after CSF shunt surgery is significant and has caught the attention of purchasers of health care. However, a detailed description of clinical scenarios that lead to readmissions and reoperations after index shunt surgery is lacking in the medical literature. METHODS This study included 1755 shunt revision and insertion surgeries that were performed at a single institution between May 1, 2009, and April 30, 2013. Demographic, socioeconomic, and clinical characteristics were prospectively collected in the administrative, business, and operating room databases. Clinical events within the 30 days following discharge were reviewed and analyzed. Two events of interest, Emergency Department (ED) utilization and reoperation, were further analyzed for risk factor associations by using multivariate logistic regression. RESULTS There were 290 readmissions within 30 days of discharge (16.5%). Admission sources included ED (n = 216), hospital transfers (n = 23), and others. Of the 290 readmissions, 184 were associated with an operation, but only 165 of these were performed by the neurosurgical service. These included surgeries for shunt occlusion and externalization (n = 150), wound revision (n = 7), and other neurosurgical procedures that were not shunt related (n = 8). The remaining readmissions (n = 106) were not associated with an operation, and only 59 patients were admitted for issues related to the index shunt surgery. When return to the ED was the dependent variable in a multivariate regression model, patients who returned to the ED were more likely to be from the Atlanta metropolitan area and to be either uninsured or insured with public assistance. When reoperation was the dependent variable, patients whose surgery started after 3 p.m. were more likely to undergo subsequent CSF shunt revision surgery on readmission. CONCLUSIONS Of the readmissions within 30 days of shunt surgery, 74.5% were related to the index shunt surgery. Whether and to what extent these readmissions are preventable continues to be controversial. Further study is needed to identify modifiable risk factors that may eventually improve patient care.

Abstract
Concussion research generally centers on physical challenges, though aspects such as social functioning and returning to school also warrant attention in pediatric populations. Restoring academic performance postconcussion remains a challenge. Here we provide recommendations addressing a uniform policy for pediatric concussion patients in academic institutions. Tools that may minimize difficulty with academic re-entry include independent educational evaluations, individualized educational programs (IEPs), student support teams (SSTs), letters of academic accommodation, time off, and 504 Plans. Recognition and treatment is crucial for symptom relief and prevention of functional disruption, as is specialist referral during the acute window. We recommend early intervention with a letter of academic accommodation and SST and suggest that 504 Plans and IEPs be reserved for protracted or medically complicated cases. Students with concussion should be observed for anxiety and depression because these symptoms can lead to prolonged recovery, decreased quality of life, and other social challenges.

Abstract
OBJECT Quality assessment measures have not been well developed for pediatric neurosurgical patients. This report documents the authors' experience in extracting information from an administrative database to establish the rate of return to system within 30 days of pediatric neurosurgical procedures. METHODS Demographic, socioeconomic, and clinical characteristics were prospectively collected in administrative, business, and operating room databases. The primary end point was an unexpected return to the hospital system within 30 days from the date of a pediatric neurosurgical procedure. Statistical methods were used to identify clinical and demographic factors associated with the primary end point. RESULTS There were 1358 pediatric neurosurgical procedures performed in the Children's Healthcare of Atlanta operating rooms in 2012, with 37.4% of these surgeries being preceded by admissions through the emergency department. Medicare or Medicaid was the payor for 54.9% of surgeries, and 37.6% of surgeries were shunt related. There were 148 unexpected returns to the system within 30 days after surgery, and in 109 of these cases, the patient had a presenting complaint that was attributable to the index surgery (related returns). The most common complaints were headache, nausea, vomiting, or seizure after shunt revision or cranial procedures (n = 62). The next most common reason for re-presentation was for wound concerns (n = 30). Thirty-seven of the 109 related returns resulted in a reoperation. The monthly rate of related returns was 8.1% ± 2.5% over the 12-month study period. When using related returns as the dependent variable, the authors found that patients who underwent a shunt-related surgery were both more likely to unexpectedly return to the system (OR 1.86, p = 0.008) and to require surgery upon readmission (OR 3.28, p = 0.004). Because an extended hospitalization shortened the window of time for readmission after surgery, extended length of stay was protective against return to system within 30 days of surgery. Importantly, if related and unrelated returns were analyzed together as the dependent variable (n = 148), no independent clinical and demographic risk factor could be identified. CONCLUSIONS Quality assessment measures need to be clearly and carefully defined, as the definition itself will impact the analytical results. Clinicians must play a leading role in the development of these measures to ensure their clinical meaningfulness.

Abstract
OBJECT Children younger than 1 year of age are unique in their physiology and comorbidities. Reports in the literature suggest that the risk factors for shunt infection may be different in this population compared with older children. Importantly, these infants often have other congenital malformations requiring various surgical interventions, which impose an additional risk of infection. METHODS In the 3-year period between 2008 and 2010, 270 patients underwent initial CSF shunt placement during the 1st year of life. Clinical characteristics, hospital course, and shunt infections were prospectively recorded in the practice and hospital electronic medical record. Special attention was given to types and timing of other invasive procedures and their relationship with shunt infection. RESULTS The average gestational age was 33.6 weeks, and the average birth weight was 2333 g. The average weight at the time of shunt insertion was 4281 g. Prior to shunt insertion, 120 patients underwent 148 surgical procedures, including ventricular access device insertion (n = 63), myelomeningocele closure (n = 37), and cardiac procedures (n = 11), among others. In the 12-month period after shunt insertion, 121 of the 270 patients underwent 135 surgical procedures, which included 79 CSF shunt revisions. Shunt infection occurred in 22 patients, and organisms were identified in 20 cases. Univariate analysis showed that of the very prematurely born infants (gestational age < 30 weeks), those who underwent preshunt cardiac surgery and any surgical procedures within 30 days after the shunt insertion were at a greater risk of shunt infection. In multivariate analysis, preshunt cardiac surgery and surgical procedures within 30 days postshunt placement were significant risk factors independent of gestational age, birth weight, and history of shunt revisions. CONCLUSIONS The results of this study suggest that surgical procedures within 30 days after shunt insertion and preshunt cardiac surgery are associated with a greater risk of shunt infection in children in whom these devices were inserted during the 1st year of life.

Abstract
Spinal cord infarctions following seemingly innocuous trauma in children are rare, devastating events. In the majority of these cases, the pathophysiology is enigmatic. The authors present 3 cases of pediatric spinal cord infarction that followed minor trauma. An analysis of the clinical, radiographic, and laboratory features of these cases suggests that thromboembolism of the nucleus pulposus into the spinal cord microcirculation is the likely mechanism. A review of the human and veterinary literature supports this notion. To the authors' knowledge, this is the largest pediatric series of myelopathy due to thromboembolism of the nucleus pulposus reported to date, and it is the first report of this condition occurring in an infant.

Abstract
A method for estimating cardiovascular dynamics and cardiac output waveforms using signals derived from two PPG sensors is presented. The method employs a novel signal-processing algorithm known as Laguerre Model Blind System Identification to identify the vascular dynamics associated with the measured PPG signals. A unique deconvolution method is then used with the identified Laguerre models to estimate the cardiac output waveform. Initial results implementing the method on data derived from a human subject is presented. Results show good agreement between the morphology of the estimated waveform and the typical morphology of the human cardiac output waveform.

Abstract
It is well known that the photoplethysmogram (PPG) is related to the underlying arterial blood pressure (ABP). However, there is ambiguity regarding the precise relationship of these two circulatory signals: some investigators have described a static relationship, while others have used more complex dynamic characterizations. This paper attempts to reconcile these models, employing results obtained from controlled human subject tests. Our data indicate that there is no simple relationship between the continuous PPG and ABP. However, when several serial beats are aggregated, a static, reproducible relationship is observed. This suggests that, in a stable experimental environment, most of the factors that decouple the ABP and PPG operate over short time scales. When these factors are eliminated through beat averaging, calibrated plethysmography offers a near-continuous estimation of ABP. Our data suggest that this PPG/ABP relationship is not stationary, since it is less consistent over time scales greater than 20 minutes. Variable local ABP was generated by raising and lowering the subjects' hands; this method also offered the means for oscillometric BP measurement without any additional actuator such as a conventional pneumatic cuff.

Abstract
We report on the growth of c-axis oriented thin films of NbFe(2) prepared by pulsed laser deposition. Variation of the deposition conditions results in variation of the composition of the Nb(1-y)Fe(2+y) films in the range from Nb rich to Fe rich films. Films near the stoichiometric composition (y ≈ 0) are the most interesting. However, microstructural investigations of these films reveal two kinds of grain, which exhibit different shape, epitaxial relation and chemical composition. The different chemical compositions of opposing doping character result in two magnetic phases confirmed by means of magnetization and Hall measurements. This investigation demonstrates the possibility of NbFe(2) thin film growth and discusses the microstructural inhomogeneities occurring.

Abstract
Vascular supply plays a significant role in the management of skull base tumors. The diagnosis is aided by contrast-enhanced imaging and angiographic techniques, and embolization procedures are used to devascularize certain lesions. The degree of surgical technical difficulty is strongly influenced by the degree of tumor vascularity. Although the importance of this blood supply is clearly understood, the mechanism involved in developing a system of tumor-perfusing vessels is yet to be defined. The development of a vascular network, or angiogenesis, is an important event in allowing tumor proliferation to progress beyond small clusters of cells. Basic fibroblastic growth factor (bFGF) is an especially attractive candidate as an angiogenic growth factor because of its ability to stimulate processes that are characteristic of angiogenesis in vitro. Tumors that involve the meninges may have the ability to liberate normally stored bFGF, which may, in turn, induce new vessel formation for continued tumor proliferation. An immunohistochemical analysis of rodent and bovine meninges to study this phenomenon is described. The dura, arachnoid, and their associated vessels are shown clearly to contain this growth factor. Ultimately, an adjuvant therapy based on the inhibition of angiogenesis may provide a reasonable alternative to aggressive surgical approaches in skull base tumors that are incompletely resectable.
