Abstract
BACKGROUND Moyamoya angiopathy is a rare cerebral vasculopathy and an underdiagnosed cause of arterial ischemic stroke in children. We aim to report the clinical and radiological presentations in a Tunisian pediatric cohort. METHODS We identified moyamoya angiopathy in pediatric patients managed at the Child Neurology Department of Hedi Chaker Sfax University Hospital between 2008 and 2020 and reviewed their clinical and radiological data as well as their evolutionary profile. RESULTS We collected 14 patients with median age 40.6 months and a female predominance (sex ratio of 0.75). An arterial ischemic stroke (AIS) revealed the disease in all patients, with the major symptom being a motor deficit. Symptoms related to a transient ischemic attack before the diagnostic consultation were reported in four patients. Carotid territory was, clinically and radiologically, the most frequently involved. Brain magnetic resonance imaging with angiography was performed in 12 patients confirming the diagnosis by revealing the development of collateral vessels. All the investigations concluded to moyamoya disease in 57.2% and moyamoya syndrome in 42.8%. The latter was related to Down syndrome in five patients and neurofibromatosis type 1 in one patient. With a mean follow-up of 2.35 years, two patients had at least two more AISs during the first two years following diagnosis and 42.8% of patients were diagnosed with vascular or poststroke epilepsy. Full recovery was noted in 14.3% of cases. CONCLUSIONS Moyamoya angiopathy in children is a serious condition that needs to be recognized due to the high risk of recurrent ischemic strokes.

Pediatric Patient with Ischemic Stroke: Initial Approach and Early Management. CHILDREN 2021; 8:children8080649. [PMID: 34438540 PMCID: PMC8394345 DOI: 10.3390/children8080649] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/21/2021] [Accepted: 07/26/2021] [Indexed: 02/05/2023]
Abstract
Acute Ischemic Stroke (AIS) in children is an acute neurologic emergency associated with significant morbidity and mortality. Although the incidence of AIS in pediatric patients is considerably lower than in adults, the overall cumulative negative impact of the quality of life could be even higher in children. The age-related variable clinical presentation could result in a delay in diagnosis and could negatively influence the overall outcome. The early management should be based on early recognition, acute transfer to pediatric AIS centre, standardised approach (ABCDE), early neurologic examination together with neuroimaging (preferable Magnetic Resonance Imaging—MRI). The treatment is based on supportive therapy (normoxemia, normocapnia, normotension and normoglycemia) in combination with intravenous/intraarterial thrombolytic therapy and/or mechanical thrombectomy in selected cases. Pediatric stroke centres, together with the implementation of local stroke management protocols, could further improve the outcome of pediatric patients with AIS.

Abstract
Background: Cerebrovascular disorders represent a group of uncommon, heterogeneous, and complex conditions in children. We reviewed the screening practice for the detection of cerebrovascular disorder in asymptomatic children referred to our neurovascular service on the basis of a positive family history and parental and/or treating physician concern.Methods: Retrospective case-note review of referrals to our neurovascular service (July 2008-April 2018). Patients were included if the referral was made for screening, on the basis of a positive family history of cerebrovascular disorder. Symptomatic children, those with previous cranial imaging, or children under the care of a clinical geneticist (i.e. due to the child or their relative having HHT or mutations in KRIT1) were not eligible for inclusion.Results: Forty-one children were reviewed, 22 males (Median age 10.7 years, range 0.6-15.6 years). This represented 22% of the total number of referrals over a 10-year period. Twenty-nine children had an MRI/MRA brain. Twenty-eight children were referred due to a family history of intracranial aneurysm and/or subarachnoid haemorrhage, but only two had two first-degree relatives affected. Ten children were referred due to a family history of arteriovenous malformation. Three children were referred due to a family history of stroke. No cerebrovascular disease was detected during the study period (n = 29).Conclusions: Parental and/or physician concern generated a substantial number of referrals but no pathology was detected after screening. Whilst general screening guidance exists for the detection of intracranial aneurysms, consensus guidelines for the screening of children with a positive family history do not, but are required both to guide clinical practice and to assuage parental and/or physician concerns.

Hypoxic-ischemic injury causes functional and structural neurovascular degeneration in the juvenile mouse retina. Sci Rep 2021; 11:12670.

Abstract
Ischemic stroke is a major cause of long-term disabilities, including vision loss. Neuronal and blood vessel maturation can affect the susceptibility of and outcome after ischemic stroke. Although we recently reported that exposure of neonatal mice to hypoxia–ischemia (HI) severely compromises the integrity of the retinal neurovasculature, it is not known whether juvenile mice are similarly impacted. Here we examined the effect of HI injury in juvenile mice on retinal structure and function, in particular the susceptibility of retinal neurons and blood vessels to HI damage. Our studies demonstrated that the retina suffered from functional and structural injuries, including reduced b-wave, thinning of the inner retinal layers, macroglial remodeling, and deterioration of the vasculature. The degeneration of the retinal vasculature associated with HI resulted in a significant decrease in the numbers of pericytes and endothelial cells as well as an increase in capillary loss. Taken together, these findings suggest a need for juveniles suffering from ischemic stroke to be monitored for changes in retinal functional and structural integrity. Thus, there is an emergent need for developing therapeutic approaches to prevent and reverse retinal neurovascular dysfunction with exposure to ischemic stroke.

Abstract
AIMS The aim of this study is to describe the outcome and management of all children who have presented with haemorrhagic stroke (HS) secondary to an arteriovenous malformation (AVM) at a single UK centre over a 13-year period. METHODS All children with HS managed at our institution (2005-2018) were identified and those with underlying AVMs were studied. Clinical and imaging data were obtained from medical records. Outcome was scored using the Recovery and Recurrence Questionnaire. RESULTS Ninety-three children (median age 8.8 years; 56 males; 8 neonates) presented with both global and focal features (28 had Glasgow Coma Score < 8). Haemorrhage was intraparenchymal in 72; prior risk factors present in 14. An underlying vascular lesion was identified in 68/93, most commonly AVM (n = 48). A systemic cause was found in 10, cerebral venous thrombosis in three, and 9 remain unidentified despite neuroradiological investigation. Median follow-up was 2.4 years, six died, and one was lost to follow-up. Outcome was rated as good in 60/86. Of the 48 AVMs, 3 were Spetzler-Martin (SM) grade 1, 21 SM 2, 21 SM3 and 3 SM4. One patient was treated conservatively as the AVM was too high risk to treat. At follow-up, 19 with AVM were angiographically cured, all with low SM grade and with the use of a single modality in 9 cases (all low SM grade). CONCLUSION Although children with acute HS are extremely unwell at presentation, supportive care results in a good outcome in the majority. Complete obliteration for childhood AVMs is challenging even with low-grade lesions with multimodal treatment.

Abstract
Pediatric stroke is an event caused by disturbance of cerebral circulation that occurs in individuals between 28 days and 18 years of age. Although an uncommon event, pediatric stroke still carries significant morbidity and mortality. Unlike adults, causes of pediatric stroke are various and include vascular, infectious, hematologic, neoplastic, and toxic etiologies. Clinical presentation of nontraumatic intracerebral hemorrhages in older children is similar to adults, however in neonates and infants signs and symptoms can be more subtle, especially with smaller hemorrhages. Management of nontraumatic intracerebral hemorrhage consists of stabilizing the patient, management of the hemorrhage itself, and reduction of the rebleeding risk. Even so, when child reaches a medical care, morbidity and mortality rates are still high. We described a case series of pediatric patients with intracerebral nontraumatic hemorrhagic stroke from different etiologies. Although increasingly recognized, such situations are still poorly described in children and our report offers a good overview on this topic.

Abstract
INTRODUCTION Mechanical thrombectomy is standard treatment for large vessel occlusion (LVO) in adults. There are no randomized controlled trials for the pediatric population. We report our single-center experience with thrombectomy of LVO in a series of pediatric patients, and perform a review of the literature. METHODS Retrospective review of consecutive pediatric thrombectomy cases between 2011 and 2018. Demographic variables, imaging data, technical aspects and clinical outcome were recorded. RESULTS In a period of 7 years, 7 children were treated for LVO at our center. Median age was 13 (2-17), and median Ped-NIHSS was 15 (3-24), and the median ASPECTS was 8 (2-10). Five patients had cardiac disease, and 2 of them were under external cardiac assistance. Median time from onset of symptoms to beginning of treatment was 7h06m (2h58m-21h38m). Five patients had middle cerebral artery occlusions. Thrombectomy was performed using a stentriever in 3 patients, aspiration in 3 patients, and combined technique in 1 patient. Six patients had good recanalization (TICI 2 b/3). There were no immediate periprocedural complications. At 3 months, 4 patients (57%) were independent (mRS score <3). Two patients died, one after haemorrhagic transformation of an extensive MCA infarct, and one due to extensive brainstem ischemia in the setting of varicella vasculitis. DISCUSSION Selected pediatric patients with LVO may be treated with mechanical thrombectomy safely. In patients under external cardiac assistance and under anticoagulation, thrombectomy is the only alternative for treatment of LVO. A multidisciplinary approach in specialized pediatric stroke centers with trained neurointerventionalists are essential for good results.

Abstract
BACKGROUND AND PURPOSE Conventional angiography is the criterion standard for measuring intracranial arterial stenosis. We evaluated signal intensity ratios from TOF-MRA as a measure of intracranial stenosis and infarct risk in pediatric stroke. MATERIALS AND METHODS A retrospective study was undertaken in children with intracranial arterial stenosis, who had TOF-MRA and conventional angiography performed within 6 months. Arterial diameters were measured for percentage stenosis. ROI analysis on TOF-MRA measured signal intensity in pre- and poststenotic segments, with post-/pre-signal intensity ratios calculated. The Pearson correlation was used to compare percentage stenosis on MRA with conventional angiography and signal intensity ratios with percentage stenosis; the point-biserial correlation was used for infarcts compared with percentage stenosis and signal intensity ratios. Sensitivity, specificity, and positive and negative predictive values were calculated for determining severe (≥70%) stenosis from MRA and signal intensity ratios against the criterion standard conventional angiography. P < .05 was considered statistically significant. RESULTS Seventy stenotic segments were found in 48 studies in 41 children (median age, 11.0 years; range, 5 months to 17.0 years; male/female ratio, 22:19): 20/41 (48.8%) bilateral, 11/41 (26.8%) right, and 10/41 (24.4%) left, with the most common site being the proximal middle cerebral artery (22/70, 31%). Moyamoya disease accounted for 27/41 (65.9%). Signal intensity ratios and conventional angiography stenosis showed a moderate negative correlation (R = -0.54, P < .001). Receiver operating characteristic statistics showed an area under the curve of 0.86 for using post-/pre-signal intensity ratios to determine severe (≥70%) carotid stenosis, yielding a threshold of 1.00. Sensitivity, specificity, and positive and negative predictive values for severe stenosis were the following-MRA: 42.8%, 58.8%, 30.0%, and 71.4%; signal intensity ratio >1.00: 97.1%, 77.8%, 71.7%, and 97.4%; combination: 75.5%, 100%, 100%, and 76.8%, respectively. Signal intensity ratios decreased with increasing grade of stenosis (none/mild-moderate/severe/complete, P < .001) and were less when associated with infarcts (0.81 ± 0.52 for arteries associated with downstream infarcts versus 1.31 ± 0.55 for arteries without associated infarcts, P < .001). CONCLUSIONS Signal intensity ratios from TOF-MRA can serve as a noninvasive measure of intracranial arterial stenosis and allow identification of high-risk lesions in pediatric stroke.

Abstract
PURPOSE There is a general lack of evidence on the efficacy of rehabilitation training methods after childhood stroke. The aim of the current paper is to provide an example of a multidisciplinary assessment and intensive patient-centered rehabilitation program that was devised following the Clinical Guidelines for Childhood Stroke Diagnosis, Management and Rehabilitation, based on the International Classification of Functioning, Disability and Health. METHOD The case of a 13-year-old teenager with physical, linguistic, cognitive and emotional impairments after acute ischemic stroke (AIS) in left middle cerebral artery territories is presented and his neurorehabilitation program is described. RESULTS After an intensive and comprehensive rehabilitation period, the patient showed significant improvement involving language abilities, cognitive flexibility, logical reasoning and motor independence. A 6-month post-stroke follow-up evaluation showed further gains in spontaneous language, improved motivation and collaboration, reduction of impulsiveness and better general motor stability. CONCLUSION This case highlights how an intensive, patient-centered, interdisciplinary rehabilitation approach can lead to good improvement across different domains, maximizing the spontaneous recovery in children and adolescents after AIS.

Abstract
Cerebral ischemia can occur at any stage in life, but clinical consequences greatly differ depending on the developmental stage of the affected brain structures. Timing of the lesion occurrence seems to be critical, as it strongly interferes with neuronal circuit development and determines the way spontaneous plasticity takes place. Translational stroke research requires the use of animal models as they represent a reliable tool to understand the pathogenic mechanisms underlying the generation, progression, and pathological consequences of a stroke. Moreover, in vivo experiments are instrumental to investigate new therapeutic strategies and the best temporal window of intervention. Differently from adults, very few models of the human developmental stroke have been characterized, and most of them have been established in rodents. The models currently used provide a better understanding of the molecular factors involved in the effects of ischemia; however, they still hold many limitations due to matching developmental stages across different species and the complexity of the human disorder that hardly can be described by segregated variables. In this review, we summarize the key factors contributing to neonatal brain vulnerability to ischemic strokes and we provide an overview of the advantages and limitations of the currently available models to recapitulate different aspects of the human developmental stroke.

Abstract
Vascular injury is increasingly recognized as an important cause of mortality and morbidity in children (29 days to 18 years of age). Since vascular brain injury in children appears to be less common than in adults, the index of suspicion for vascular brain injury is usually lower. In this review article, we describe frequent and rare conditions underlying pediatric stroke including cardioembolic, viral, autoimmune, post-traumatic, and genetic etiologies. Furthermore, we provide a neuroimaging correlate for clinical mimics of pediatric stroke. This review highlights the role of multimodal noninvasive neuroimaging in the early diagnosis of pediatric stroke, providing a problem-solving approach to the differential diagnosis for the neuroradiologist, emergency room physician, and neurologist.

Abstract
PURPOSE OF REVIEW This article provides an overview of stroke in neonates, infants, and children. RECENT FINDINGS Arterial ischemic stroke and cerebral venous sinus thrombosis are increasingly recognized in childhood as important causes of lifelong morbidity and mortality. Diagnosis of arterial ischemic stroke is frequently delayed, as acute neurologic deficits can be challenging to detect in the young child, and stroke is often not considered in the differential diagnosis. Neurologic sequelae following stroke are common, and strategies to minimize stroke size and optimize recovery are being developed. Recurrent arterial ischemic stroke is not uncommon, particularly in children with cerebral arteriopathy. Cerebral venous sinus thrombosis causes obstruction of venous outflow leading to venous infarcts. Complications include hemorrhagic conversion of infarcts and increased intracranial pressure. Without treatment, thrombus extension with increased symptoms is common. Robust guidelines of care that exist for adults do not exist for children, particularly for children with arterial ischemic stroke. SUMMARY The approach to stroke in infants and children can be informed by clinical experience in pediatric stroke and cerebral venous sinus thrombosis, the extensive literature on pediatric thrombosis, and extrapolation from data from adult patients.

Abstract
Children and young adults tend to have reduced mortality and disability after acquired brain injuries such as trauma or stroke and across other disease processes seen in critical care medicine. However, after out-of-hospital cardiac arrest (OHCA), outcomes are remarkably similar across age groups. The consistent lack of witnessed arrests and a high incidence of asphyxial or respiratory etiology arrests among pediatric and young adult patients with OHCA account for a substantial portion of the difference in outcomes. Additionally, in younger children, differences in pre-hospital response and the activation of developmental apoptosis may explain more severe outcomes after OHCA. These require us to consider whether present practices are in line with the science. The present recommendations for compression-only cardiopulmonary resuscitation in young adults, normothermia as opposed to hypothermia (33°C) after asphyxial arrests, and paramedic training are considered within this review in light of existing evidence. Modifications in present standards of care may help restore the benefits of youth after brain injury to the young survivor of OHCA.

Abstract
Primary immune thrombocytopenia (ITP) is the most common cause of thrombocytopenia in children and adolescents and can be considered as a paradigmatic model of autoimmune disease. This second part of our review describes the clinical presentation of ITP, the diagnostic approach and overviews the current therapeutic strategies. Interestingly, it suggests an algorithm useful for differential diagnosis, a crucial process to exclude secondary forms of immune thrombocytopenia (IT) and non-immune thrombocytopenia (non-IT), which require a different therapeutic management. Advances in understanding the pathogenesis led to new therapeutic targets, as thrombopoietin receptor agonists, whose role in treatment of ITP will be discussed in this work.

Abstract
OBJECTIVES: The number of deaths from vascular diseases is incredibly high worldwide, and reliable markers for major events are still needed. The current cross-sectional study investigated the association of Klotho haplotypes and Klotho serum levels with classic risk factors and a clinical history of vascular events. METHODS: Clinical, anthropometric, biochemical and nutritional assessments were conducted with 168 older adults, complemented by genotyping (rs9536314 and rs9527025) and the detection of serum Klotho (ELISA). RESULTS: Klotho levels and haplotypes did not associate with most classic risk factors for vascular events, including markers such as C-reactive protein and homocysteine. A positive association was only found between Klotho levels and the previous occurrence of a myocardial infarction by both correlational (p=0.006) and variance analyses (p<0.001), and these associations were independent of the context. CONCLUSION: Our results suggest that serum Klotho is higher in individuals with a clinical history of myocardial infarction but not with a history of coronary artery disease or stroke. None of the Klotho haplotypes were associated with the variables investigated herein.

Abstract
Stroke in children carries lasting morbidity. Once recognized, it is important to evaluate and treat children with acute stroke efficiently and accurately. All children should receive neuroprotective measures. It is reasonable to consider treatment with advanced thrombolytic and endovascular agents. Delivery of such care requires purposeful institutional planning and organization in pediatric acute care centers. Primary stroke centers established for adults provide an example of the multidisciplinary approach that can be applied to the evaluation and treatment of children who present with acute stroke. The organizational infrastructure of these centers can be employed and adapted for treatment of children with acute stroke. It is likely that care for children with acute stroke can best be delivered by regional pediatric primary stroke centers dedicated to the care of children with pediatric stroke.

Abstract
AIM To assess outcome after neonatal perforator stroke in the largest cohort to date. METHOD Survivors from a cohort of children diagnosed with neonatal perforator stroke using cranial ultrasound or magnetic resonance imaging were eligible for inclusion. Recovery and Recurrence Questionnaire score, presence of cerebral palsy (CP), and crude outcome were assessed, specifically (1) the ability to walk independently, (2) participation in regular education, and (3) the presence of epilepsy. RESULTS Thirty-seven patients (20 males, 17 females) aged 3 to 14 years (mean age 8y) were included in the study: 14 with isolated single perforator stroke, four with multiple isolated perforator strokes, and 19 with additional brain injury. Out of 18 children with isolated perforator stroke(s), four had CP, one could not walk independently, and one developed epilepsy. The posterior limb of the internal capsule was involved in four out of 18 patients; three of these patients had CP. Of 19 children with additional brain injury, 11 had CP and three were not able to walk independently. Three out of nine children with concomitant cortical middle cerebral artery stroke developed epilepsy. INTERPRETATION Perforator stroke patterns can be of use in predicting long-term outcome and for guiding counselling and surveillance. Motor outcome was favourable in children with isolated perforator stroke(s), except when the posterior limb of the internal capsule was involved.

Abstract
There are scarce reports of childhood stroke from China. Our objective was to describe the clinical spectrum, risk factors, and imaging characteristics of childhood stroke in China. Using a hospital discharge database, children with stroke who were first admitted from 2002 to 2011 were retrospectively enrolled. We identified 478 first admissions with childhood stroke, including 229 cases of ischemic stroke and 249 hemorrhagic stroke. Boys accounted for more than 60% in all stroke types (62.2% for ischemic stroke, intracerebral hemorrhage for 66.2%). The leading cause was moyamoya for ischemic stroke and arteriovenous malformations for intracerebral hemorrhage. Hemiplegia and headache were the most common presenting features. Internal carotid artery and middle cerebral artery were the most involved arteries according to imaging examination in the ischemic stroke. A total of 8 patients died of intracerebral hemorrhage. The prevalence of hemorrhagic stroke was more than that of ischemic stroke. As Western countries, arteriopathy was the most common cause of childhood stroke.

Abstract
PURPOSE To examine the long-term functional, psychosocial, and medical outcome of pediatric stroke survivors. METHOD This was a descriptive survey performed on patients with childhood stroke who participated in an earlier study. Measures included the Vineland Adaptive Behavior Scales (VABS) and the Diener Satisfaction with Life Scale. Current information on living situation, school placement, employment, and medical outcome were obtained. RESULTS Twenty-nine (58%) patients participated. The mean age was 19.3 years (SD = 6.6), mean age of onset of stroke was 7.0 years (SD = 5.4), and mean follow-up time was 11.9 years (SD = 3.9). Diagnoses included hemorrhagic (31%) and ischemic (69%) stroke. All but one adult had finished high school, and the majority of participants had gone to college. 60% of patients over age 16 were employed. The average VABS levels for communication, daily living skills, socialization, and adaptive behavior fell into the moderately low range. Use of seizure medications and ADL dependence were the predictors for lower VABS levels (p <.05). Younger age, ischemic stroke, and previous dependence in mobility were risk factors for lower scores for the self-care domain, but not for lower life satisfaction. Patients who scored below adequate on VABS tended toward lower life satisfaction. CONCLUSION Pediatric stroke survivors had good educational and mobility outcomes, but communication, ADL, and socialization fell into the low-moderate range. The different predictors of functional and subjective quality of life outcomes suggest that functional outcomes may mediate the relations between medical factors and satisfaction with life.

Abstract
The incidence of arterial ischemic stroke (AIS) in childhood (about 2-13 per 100,000 children a year) is much lower than the incidence in the adult population. Still, adverse outcomes of acute brain ischemia in childhood include death (10% of AIS children), neurological sequel, epileptic seizures (over 50%) and recurrence (over 20%). The knowledge of childhood stroke etiopathogenesis is still insufficient and the diagnostic and therapeutic procedures--controversial. Risk factors for childhood stroke differ from those observed in adults due to differing exposure to external risk factors. The most frequently reported risk factors for pediatric ischemic stroke are cerebral arteriopathies and vascular malformations, cardiac diseases, infections, traumas and metabolic diseases. Because of its multifactorial etiology pediatric AIS probably has a multigenic inheritance pattern. The genetic susceptibility to AIS may be determined by specific polymorphic variants encoding markers of hemostasis regulation and they are some of the most important targets in searching for genetic determinants in pediatric AIS. The authors have reviewed the recent literature on risk factors of childhood ischemic stroke with the focus on genetic factors like polymorphisms of genes encoding coagulation factors II, V, VII and XIII, MTHFR, fibrinogen beta, and compared them with the results performed in adult patients.

Abstract
BACKGROUND Post-traumatic carotid artery dissection (PTCAD) may result in acute arterial ischemic stroke (AIS). Pediatric PTCAD is rarely diagnosed prior to onset of neurological symptoms. We report on neuroimaging findings in a series of children with PTCAD. METHODS Five children with head or neck trauma were included in this study. Clinical histories were reviewed for mechanism of trauma, symptoms, complications, therapy, and outcome. Computed tomography (CT), magnetic resonance imaging (MRI), and CT/MR angiography (CTA, MRA) studies were retrospectively evaluated for signs and complications of PTCAD and presence and extent of skull base fractures. RESULTS PTCAD was located at the level of the skull base in all children and was associated with a skull base fracture in two. The diagnosis was made in five children by combined MRI/MRA and in two by CTA. Air in the carotid canal suggested skull base injury with PTCAD in two children. PTCAD was complicated by AIS in three children. CONCLUSION PTCAD may result from neck and head trauma. To avoid secondary AIS, radiologists should be familiar with neuroimaging findings in children, especially as acute PTCAD may initially be clinically silent. Consequently, pediatric neuroradiologists should actively exclude PTCAD in children with head and neck trauma.

Abstract
National organizations recommend cholesterol screening in children to prevent vascular disease in adulthood. There are currently no recommendations for cholesterol and lipoprotein (a) testing in children who experience an arterial ischemic stroke. While dyslipidemia and elevated lipoprotein (a) are associated with ischemic stroke in adults, the role of atherosclerotic risk factors in childhood arterial ischemic stroke is not known. A review of the literature was performed from 1966 to April 2012 to evaluate the association between childhood arterial ischemic stroke and dyslipidemia or elevated lipoprotein (a). Of 239 citations, there were 16 original observational studies in children (with or without neonates) with imaging-confirmed arterial ischemic stroke and data on cholesterol or lipoprotein (a) values. Three pairs of studies reported overlapping subjects, and two were eliminated. Among 14 studies, there were data on cholesterol in 7 and lipoprotein (a) in 10. After stroke, testing was performed at >three-months in nine studies, at ≤three-months in four studies, and not specified in one study. There were five case-control studies: four compared elevated lipoprotein (a) and one compared abnormal cholesterol in children with arterial ischemic stroke to controls. A consistent positive association between elevated lipoprotein (a) and stroke was found [Mantel-Haenszel OR 4·24 (2·94-6·11)]. There was no association in one study on total cholesterol, and a positive association in one study on triglycerides. The literature suggests that elevated lipoprotein (a) may be more likely in children with arterial ischemic stroke than in control children. The absence of confirmatory study on dyslipidemia should be addressed with future research.

Abstract
PURPOSE The aim of our study was to evaluate treatment results and toxicity of stereotactic irradiation for arteriovenous malformations (AVMs) in children. METHODS A group of ten consecutive children (four boys and six girls) irradiated between 2002 and 2010 at our institution was included into the study. The mean age at the time of treatment was 15.4 and ranged between 8 and 18 years. There were two Spetzler-Martin grade IV, four grade III, and four grade II lesions. Mean AVM volume was 13.2 cm(3) and varied from 0.6 to 36.8 cm(3). In five patients, the planned dose of 16-20 Gy was delivered in single fraction, in five the total dose of 16-24 Gy was delivered in two to three fractions. One patient was reirradiated with a dose of 15 Gy, 7 years after the initial treatment. RESULTS The median follow-up was 38.5 months. The treatment resulted in total obliteration in eight patients and partial in one. The median time to obliteration was 22 months; actuarial total obliteration rates were 20, 54, 54, and 83 % after 1, 2, 3, and 4 years of follow-up, respectively. No patient bled after the treatment. In one patient, new epileptic seizures developed after the treatment; in magnetic resonance imaging, focal necrosis was revealed. In five patients, asymptomatic imaging abnormalities were seen during follow-up. CONCLUSIONS Stereotactic radiotherapy appears to be an effective method of treatment for pediatric AVMs, the patients however require meticulous follow-up because of relative high incidence of radiation-induced imaging abnormalities.

Abstract
PURPOSE This study aimed to estimate the prevalence and incidence of cerebrovascular disease (CVD) and stroke in Korean male adolescents. MATERIALS AND METHODS The authors reviewed all medical certificates, medical records, and radiologic images from the examinations of Korean military conscription from January 2008 to May 2011. RESULTS Of the 101,156 examinees, 40 had CVD and stroke during adolescence. The overall prevalence and incidence of CVD and stroke was 39.54 cases per 100,000 adolescents and 2.08 cases per 100,000 adolescents per year, respectively and these were similar to the worldwide data. There were 3 cases of aneurysm, 3 cases of dural arteriovenous fistula, 11 cases of arteriovenous malformation, 4 cases of cavernous hemangioma, 4 cases of cerebrovascular infarction, 16 cases of Moyamoya disease, and 1 case of missing data. The incidence of arteriovenous malformation (0.57 cases per 100,000 adolescents per year) was lower than the incidence for the worldwide general population. The incidence of Moyamoya disease was higher than that in any other country (15.82 cases per 100,000 adolescents, vs. 0.83 cases per 100,000 adolescents per year). CONCLUSION We observed ischemic and hemorrhagic stroke, each accounting for approximately half of cases, and high incidence of Moyamoya disease with low incidence of arteriovenous malformation in Korean male adolescents.

Abstract
Stroke in children is rarely due to traditional stroke risk factors such as hypertension and diabetes. Rather, stroke in this patient group typically results from the simultaneous occurrence of multiple stroke risk factors, the presence of which necessitates a thorough evaluation to determine the cause of this disorder. Several challenges exist in the care of children with stroke. Of note, recognition of pediatric stroke onset by parents and caregivers is often delayed, highlighting the need for increased awareness of and education regarding this condition. Moreover, various neurological conditions resemble stroke in pediatric patients and a definite diagnosis of this disorder requires MRI; adding to the diagnostic challenge, young children may need to be sedated to undergo acute MRI. Perhaps the most significant challenge is the need for clinical research studies focusing on pediatric stroke treatment, so as to allow evidence-based treatment decision-making. A final challenge is the standardization of outcome assessment after stroke for a wide range of ages and developmental levels. In this Review, we examine recent findings and diagnostic issues pertaining to both arterial ischemic stroke and hemorrhagic stroke in children.

Abstract
BACKGROUND Ischemic stroke in children can present with an epileptic seizure or be initially asymptomatic. The median time to diagnosis is 24 hours. METHODS This review is based on a selective literature search, with additional consideration of published guidelines and the authors' personal experience. RESULTS In Europe and the USA, the combined incidence of ischemic and hemorrhagic stroke in childhood is 2.5 to 10 per 100 000 children per year. 40% of ischemic strokes in childhood occur after an infectious illness or in association with a congenital heart defect, sickle-cell anemia, or a coagulopathy. Arterial dissection and chronic, progressive cerebral arteriopathies, particularly moyamoya disease, each account for up to 10% of childhood strokes. Magnetic resonance imaging can be used to demonstrate infarcts and to display the perfusion of ischemic areas and the surrounding brain tissue; arterial and venous occlusions can be defined more precisely. Children with arterial dissection, vasculitis, and para-infectious cerebral ischemia should be treated empirically, with medications and supportive care, according to the treatment plans developed for adults. For patients with moyamoya disease, surgical revascularization with extra-intracranial bypass techniques is recommended. DISCUSSION The current data provide an inadequate evidence base for the treatment of stroke in children. Potential revascularization or thrombolysis must be discussed individually in each case. For the treatment of temporary, para-infectious cerebral ischemia, hemodynamic optimization is an available option. Better evidence is needed regarding the surgical treatment of moyamoya disease.

Abstract
Sudden unexpected death is any nontraumatic death in healthy individuals with normal activities for age until acute demise. Whereas not uncommon in adults and infants, it is considered a rarity in children, with most cases due to infection or occult cardiovascular abnormalities. Pathologic intracranial findings are rarely found in sudden unexpected death in childhood, with most cases due to occult intracranial neoplasms. Cerebral arterial dissection is an uncommon cause of arterial ischemic stroke in childhood. Outcome is poor, with more than 20% of patients dying. We report 4 cases of sudden unexpected death due to arterial ischemic stroke after cerebral arterial dissection in childhood and present a review of the literature.

Abstract
OBJECT The aim of this study was to evaluate the long-term imaging and clinical outcomes of intracranial arteriovenous malformations (AVMs) in children treated with Gamma Knife surgery (GKS). METHODS Between 1989 and 2007, 200 patients with AVMs who were 18 years of age or younger were treated at the University of Virginia Health System. Excluding 14 patients who had not reached 2-year follow-up, 186 patients comprised this study. Hemorrhage was the most common presenting symptom leading to the diagnosis of AVMs (71.5%). The mean nidus volume was 3.2 cm(3) at the time of GKS, and a mean prescription dose of 21.9 Gy was used. RESULTS After initial GKS, 49.5% of patients achieved total angiographic obliteration. Forty-one patients whose AVM nidi remained patent underwent additional GKS. The obliteration rate increased to 58.6% after a second or multiple GKS. Subtotal obliteration was achieved in 9 patients (4.8%). Forty-nine patients (26.3%) still had a patent residual nidus. In 19 patients (10.2%), obliteration was confirmed on MR imaging only. Ten patients had 17 hemorrhages during the follow-up period. The hemorrhage rate was 5.4% within 2 years after GKS and 0.8% between 2 and 5 years. Six patients developed neurological deficits along with the radiation-induced changes. Two patients developed asymptomatic meningiomas 10 and 12 years after GKS. After a mean clinical follow-up of 98 months, less than 4% of patients had difficulty attending school or developing a career. CONCLUSIONS Gamma Knife surgery offers a reasonable chance of obliteration of an AVM in pediatric patients. The incidence of symptomatic radiation-induced changes is relatively low; however, long-term clinical and imaging follow-up is required to identify delayed cyst formation and secondary tumors.

Abstract
PURPOSE Population-based estimates of the annual incidence of childhood stroke range from 2 to 13 per 100,000 person-years. More than half of children who have had a stroke have long-term neurological sequelae. The goal of this article is to review recent literature on both hemorrhagic and ischemic stroke in children with a focus on cerebral arteriopathy and vascular malformations as stroke risk factors. Additionally, we review diagnostic studies for childhood stroke, outcome data, and regional and geographic practice differences. METHODS PubMed was searched using the terms child, childhood, pediatric, stroke, ischemic, intracerebral hemorrhage, vasculopathy, and vascular malformation. Reference lists of these articles were reviewed for additional key publications. Preference was given to articles published since the year 2000; however, seminal articles in the field were also reviewed. RESULTS Pediatric stroke is a heterogeneous disorder and a major cause of morbidity in the pediatric population. Five-year recurrence risk is estimated to be 5-19%. Children with cerebrovascular abnormalities are at the highest risk of recurrence (66% at 5 years for ischemic stroke in one study). Furthermore, cerebral arteriopathy including arterial dissection may account for up to 80% of childhood stroke in otherwise healthy children. CONCLUSION In many cases, evaluation and treatment of pediatric stroke is not evidence-based, and regional and geographic variations in practice patterns exist. Ultimately multicenter cohort studies and dedicated pediatric clinical trials are essential to establish comprehensive evidence-based guidelines for pediatric stroke care.

Abstract
BACKGROUND The pattern of pediatric stroke displays ethnic and geographical variations. There are few reports from black Sub-Saharan Africa, although relevant data are important in prevention, clinical diagnosis, treatment and prognostication. AIM To describe subtypes, risk factors, localization, age and gender distribution of pediatric stroke in the black Kenyan population. STUDY DESIGN AND SETTING Retrospective cross-sectional study in a single regional referral and teaching hospital. STATISTICAL ANALYSIS Data were analyzed by SPSS version 13.0 for Windows and presented in tables and bar and pie charts. MATERIALS AND METHODS The study was performed at the Kenyatta National Hospital, a level-6 regional referral health facility with an annual pediatric in-patient turnover of about 40,000 patients. Files of patients aged 1 month to 18 years over a period of 5 years were analyzed for stroke subtypes, localization, risk factors, age and sex distribution. Only those files with complete information were included. RESULTS Thirty-two of the 712 stroke patients (4.5%) were pediatric. The male:female ratio was 1.7:1. Ischemic stroke comprised 56.3% (n = 18). Mean age was 7.7 years (range, 1.5-18 years). The most common sites were cortical (51%), lacunar (41%) and brain stem (8%). The most common risk factors were connective tissue disorders (28.1%), heart disease (25%), human immunodeficiency virus (9.4%) and infection (9.4%). CONCLUSION Pediatric stroke is not uncommon in the Kenyan population. The risk factor profile comprising connective tissue disorders and infection differs from that reported in other populations, inviting large community-based studies.

Abstract
We present 28 patients with basal ganglia ischemic stroke and describe the main neurological manifestations, neuroimaging findings, risk factors, and outcome. In 23 cases, at least 1 risk factor was identified. A total of 7 cases (25%) had antecedent of varicella infection and 7 cases (25%) had preceding mild head trauma. Similar antecedents were present only in 2.6% and 5.3% of patients with nonbasal ganglia stroke, respectively (odds ratio: 12.2, 95% confidence interval: 2.04-124.65 and odds ratio: 5.92, 95% confidence interval: 1.32-29.7). The arterial abnormalities identified in 10 patients were narrowing (6) or occlusion (4) of the M1 segment. After a median follow-up of 24 months, 19 patients had a good outcome. Magnetic resonance angiography and catheter cerebral angiography played an important role in the identification of arterial disease. We propose that basal ganglia infarction is a different group of ischemic stroke with prevalent risk factors (varicella infection and mild head trauma) and good outcome.

Abstract
OBJECTIVES Predictors for perinatal arterial ischemic stroke include both maternal and intrapartum factors, but predictors of perinatal hemorrhagic stroke have not been studied. We sought to determine both the prevalence and predictors of perinatal hemorrhagic stroke within a large, multiethnic population. PATIENTS AND METHODS We performed a case-control study nested within the cohort of all infants born from 1993 to 2003 in the Northern California Kaiser Permanente Medical Care Program, a health maintenance organization providing care for >3 million members. Cases of symptomatic perinatal hemorrhagic stroke and perinatal arterial ischemic stroke in neonates (28 weeks' gestational age through 28 days of life) were identified through electronic searches of diagnosis and radiology databases and confirmed by medical chart review. Three controls per case were randomly selected and matched on birth year and facility. This analysis included cases of perinatal hemorrhagic stroke (intracerebral hemorrhage or subarachnoid hemorrhage, excluding pure intraventricular hemorrhage) and all controls. Predictors of perinatal hemorrhagic stroke were assessed by using logistic regression, adjusting for the matching criteria. RESULTS Among 323 532 live births, we identified 20 cases of perinatal hemorrhagic stroke (19 intracerebral hemorrhage and 1 subarachnoid hemorrhage), which yielded a population prevalence for perinatal hemorrhagic stroke of 6.2 in 100 000 live births. Cases presented with encephalopathy (100%) and seizures (65%). Perinatal hemorrhagic stroke was typically unifocal (74%) and unilateral (83%). Etiologies included thrombocytopenia (n = 4) and cavernous malformation (n = 1); 15 (75%) were idiopathic. Univariate predictors of perinatal hemorrhagic stroke included male gender, fetal distress, emergent cesarean delivery, prematurity, and postmaturity but not birth weight. When entered into a multivariate model, fetal distress and postmaturity continued to be independent predictors. CONCLUSIONS Fetal distress is an independent predictor of perinatal hemorrhagic stroke, perhaps suggesting a prenatal event. Postmaturity also predicts perinatal hemorrhagic stroke, an association not explained by large birth weight in our study.

Abstract
The aim of the study was to estimate the preponderance of patterns of pediatric stroke, ischemic or hemorrhagic, their etiologies and the correct diagnostic protocol for acute management. Forty-one consecutive pediatric patients (age range 5-16 years) with an acute stroke observed in acute phase during a 10-year period, were retrospectively evaluated. Twenty-three patients underwent magnetic resonance imaging (MRI), 3 cases were studied by computed tomography (CT) without MRI, and 15 underwent both CT and MRI studies. In 9 cases, intra-arterial digital subtraction angiography (IADSA) was performed after non-invasive preliminary assessment. Seventeen hemorrhagic (41%) and 24 ischemic (59%) strokes were found. Among hemorrhagic forms, 5 cases were due to arteriovenous malformation (AVM), 7 to cavernoma, and 2 to aneurysm. Among ischemic forms, 2 were due to sickle-cell disease, 1 to hyperomocysteinemia, 1 to moyamoya syndrome, 1 to pseudoxantoma elasticum, 3 to prothrombotic state, 1 to Fabry's disease, 1 concomitant with CO intoxication, 5 to venous sinus thrombosis, and 4 to cardio-embolic state. Etiology remains unknown in 8 cases (20.5%). This study shows a moderate prevalence of ischemic over hemorrhagic strokes. Moreover, personal experience suggests that MRI is always more informative than CT and in selected cases should be the first-choice examination in the acute phase.

Abstract
OBJECT Ischemic cerebral vascular accidents (CVAs) in children result in epilepsy in 25% of patients, which is refractory in 7% of cases. Repeated seizures worsen the global and cognitive prognosis of these patients. To evaluate the prognosis of epilepsy and cognitive development in children with refractory seizures following a CVA, the authors retrospectively studied the effectiveness of periinsular hemispherotomy in the treatment of these patients. METHODS Between March 1995 and November 2007, 8 children who suffered from stroke-induced refractory epilepsy underwent a periinsular hemispherotomy. All patients' charts were reviewed in a retrospective manner. Age at the time of the CVA, imaging studies, cause of the ischemic event, onset of the first seizure, patient's handedness, the extent of the parenchymal damage, electroencephalography findings, type of epileptic seizures, number of seizures per day, number of antiepileptic medications, preoperative neuropsychological evaluation, and surgical outcome with regard to the patient's seizure activity were analyzed. RESULTS There were 7 boys and 1 girl in this study. The mean age at stroke was 23 months (range birth-5 years). The mean age at onset of epilepsy was 22 months (range 0-60 months). The mean age at the time of the hemispherotomy was 7 years (range 54-130 months). The average delay prior to the hemispherotomy was 5 years and 3 months (range 23-115 months). Prior to surgery, the average number of seizures per day was 35 (range 5-100). The average number of antiepileptic medications introduced before the hemispherotomy was 8 (range 6-12). Six patients required only 1 surgical intervention and 2 necessitated 2 separate operations:1 underwent a 2-staged hemispherotomy and the other underwent a prior callosotomy. There were no reported surgical complications in this series. Seven children are seizure free. However, the remaining child, after a 3.5-year disease-free interval, has recently started having seizures. No child demonstrated an improvement in neuropsychological evaluation. CONCLUSIONS The periinsular hemispherotomy must be considered an alternative in the therapeutic approach to stroke-induced pediatric refractory epilepsy. It is effective in controlling seizure activity. The authors believe the delay before hemispherotomy must be shortened in children with post-CVA refractory epilepsy.

Abstract
Childhood stroke syndromes are an important cause of mortality and morbidity. This paper focuses on the recent advances in arterial ischaemic stroke beyond the neonatal period. Vascular risk factors are identified in the majority of children and guide both acute and longer term treatments, as well as determining prognosis. Contrary to popular belief many children have residual impairments encompassing a wide range of domains. National and international collaborations are facilitating an increase in the understanding of childhood stroke and have the eventual aim of conducting trials of potential therapeutic interventions.

Abstract
OBJECTIVE To study the etiological profile of childhood stroke and its relation with prothrombotic states. METHODS Children with acute stroke with no evidence of CNS infection or head injury were studied. Stroke was confirmed by CT scan and further evaluated by MRI. Cardiac status was assessed with transthoracic echocardiography. Test for hypercoagulable state (antithrombin III, protein C, protein S, anticardiolipin antibody IgG and IgM and lupus anticoagulant) were done in all patients. RESULTS A total of 66 children were enrolled--36 cases and 30 controls. Presenting symptoms were motor deficit (72%), seizure (66%), altered sensorium (36%), aphasia (27%). Causes identified were antiphospholipid antibody syndrome (25%), Moya Moya disease (16.6%), cardiac disease (11.1%), vasculitis (5.5%), ATIII deficiency (5.5%), Protein C deficiency (2.7%). Etiology remained unknown in 25% of cases with infarction. Hemorrhage was seen in 8.2% of cases and they had DIC or liver disease as the underlying cause. CONCLUSIONS Magnetic Resonance Angiography and ELISA for antiphospholipid antibody should be done in all patients with stroke without an obvious cause.

Abstract
The authors report the case of a 4-year-old boy with a spontaneous intracerebral hemorrhage (ICH) related to an arteriovenous malformation (AVM) that was not found with good-quality magnetic resonance (MR) imaging and MR angiography. Both modalities were used serially in the acute phase and at 2 and 7 months of follow-up. Digital subtraction angiography identified the peripheral AVM when the patient experienced rehemorrhaging 1 year after his initial presentation. This case illustrates the need for a complete diagnostic evaluation including conventional angiography in cases of idiopathic ICH in children.

Abstract
The occurrence of spontaneous subdural hematoma (SDH) in immune thrombocytopenia (ITP) is rare. We report a spontaneous subacute subdural hematoma in a patient with chronic ITP. The patient presented with headache and a noncontrast head CT scan showed an 11 mm subacute right frontoparietal SDH causing an 8 mm right to left midline shift. The patient underwent medical management with platelets, FFP and packed RBC transfusions, steroids, IVIG and mannitol, which failed to prevent deterioration of her clinical condition. The patient then underwent burr hole drainage of the SDH. Her postoperative course was complicated by ischemic infarcts in the right posterior cerebral artery territory leaving her with a residual left homonymous hemianopia. Our patient was unique in the concurrent development of ischemic infarcts postoperatively, following burr hole drainage of the SDH in the setting of ITP. This case highlights the diagnostic and therapeutic dilemmas involved in taking care of such patients.

Abstract
Hemorrhagic stroke accounts for approximately half of stroke in childhood. Unlike arterial ischemic stroke, there are no consensus guidelines to assist in the evaluation and treatment of these children. This article reviews the literature on the evaluation, treatment, etiology, and neurologic outcome of hemorrhagic stroke in children. Important differences between pediatric and adult hemorrhage are highlighted, as treatment guidelines for adults may not be applicable in all cases. Required future research and potential therapies are also discussed.
