Abstract
OBJECTIVE To describe the incidence, clinical characteristics, and long-term outcomes of cerebral sinus venous thrombosis in children with acute lymphoblastic leukemia. METHODS This was a retrospective cohort study comprising pediatric patients with newly diagnosed or first-relapse acute lymphoblastic leukemia who developed cerebral sinus venous thrombosis at Texas Children's Hospital from 2002 to 2019. RESULTS Nineteen cases (1.7%) with cerebral sinus venous thrombosis were identified in all pediatric patients with acute lymphoblastic leukemia (n = 1129). Increased risk of cerebral sinus venous thrombosis was observed with age >10 years (P = .006). Twelve cases (63%) occurred during the induction, 4 (21%) during maintenance, and 3 (16%) during the consolidation phases of leukemia therapy. Seizures (10/19) and headaches (9/19) were the most common presenting symptoms. After treatment with anticoagulation therapy, we observed full resolution of thrombosis in 10 (53%) and partial resolution in 8 patients (42%). Long-term neurologic outcomes at follow-up in the 14 patients who survived included normal neurologic examinations (n = 10), epilepsy (n = 3), and focal neurologic deficits (n = 2). The death occurred in 5 individuals. CONCLUSION Cerebral sinus venous thrombosis is a notable complication of pediatric acute lymphoblastic leukemia therapy. Older age (>10 years) was a risk factor for developing cerebral sinus venous thrombosis. Despite variable patient presentations and treatment durations, favorable clinical outcomes were observed in most patients after the treatment with anticoagulation for a minimum of 3 months.

J-shaped associations of pan-immune-inflammation value and systemic inflammation response index with stroke among American adults with hypertension: evidence from NHANES 1999-2020. Front Neurol 2024; 15:1417863. [PMID: 39144717 PMCID: PMC11322096 DOI: 10.3389/fneur.2024.1417863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Accepted: 07/23/2024] [Indexed: 08/16/2024] Open
Abstract
Introduction Stroke, a leading cause of death and disability worldwide, is primarily ischemic and linked to hypertension. Hypertension, characterized by systemic chronic inflammation, significantly increases stroke risk. This study explores the association of novel systemic inflammatory markers (SII, PIV, SIRI) with stroke prevalence in hypertensive U.S. adults using NHANES data. Methods We analyzed data from hypertensive participants in the NHANES 1999-2020 survey, excluding those under 20, pregnant, or with missing data, resulting in 18,360 subjects. Systemic inflammatory markers (SII, PIV, SIRI) were calculated from blood counts. Hypertension and stroke status were determined by self-report and clinical measurements. Covariates included sociodemographic, lifestyle, and medical history factors. Weighted statistical analyses and multivariate logistic regression models were used to explore associations, with adjustments for various covariates. Ethical approval was obtained from the NCHS Ethics Review Board. Results In a cohort of 18,360 hypertensive individuals (mean age 56.652 years), 7.25% had a stroke. Stroke patients were older, had lower PIR, and were more likely to be female, single, less educated, smokers, non-drinkers, physically inactive, and have diabetes and CHD. Multivariate logistic regression showed that SII was not significantly associated with stroke. However, PIV and SIRI were positively associated with stroke prevalence. Each unit increase in lnPIV increased stroke odds by 14% (OR = 1.140, p = 0.0022), and lnSIRI by 20.6% (OR = 1.206, p = 0.0144). RCS analyses confirmed J-shaped associations for lnPIV and lnSIRI with stroke. Stratified analyses identified gender and smoking as significant effect modifiers. Smoking was significantly associated with elevated PIV, SIRI, and SII levels, especially in current smokers. Conclusion Elevated PIV and SIRI levels significantly increase stroke prevalence in hypertensive individuals, notably among males and smokers. A predictive model with PIV, SIRI, and sociodemographic factors offers strong clinical utility.

Abstract
BACKGROUND Recent years have seen considerable changes in the prevention and treatment of acute ischaemic stroke in adult patients. However, the low incidence of paediatric stroke makes the development of specific guidelines more challenging. This study aims to clarify the situation of these children in our region in order to establish a regional protocol to improve the care provided to these patients. METHODS We performed a regional incidence study of pediatric stroke (≤ 15 years of age) in Aragon, Spain (1308728 population, 15% aged ≤ 15 years) between 2008 and 2019. Data were obtained from hospital discharge records, including deaths, from the regional health service of Aragón, according to ICD codes for cerebrovascular disease. We analysed demographic, clinical, diagnostic/therapeutic, and prognostic variables. RESULTS A total of 21 events were recorded: 8 ischaemic (38.1%) and 13 haemorrhagic strokes (61.9%). The mean age (SD) was 9.3 years (1.0). The sample included 12 boys and nine girls. No statistically significant differences were found between ischaemic and haemorrhagic strokes, except in the chief complaint (language and motor impairment in ischaemic stroke and headache in haemorrhagic stroke). None of the patients with ischaemic stroke received reperfusion therapies. Including the 3 patients who died during hospitalisation, eight patients (42.1%) had modified Rankin Scale scores > 2 at 12 months. Motor deficits were the most common sequela (n=9). CONCLUSION Though infrequent, paediatric stroke has an important functional impact. In Spain, Madrid was the first region to adapt the existing code stroke care networks for adult patients. In Aragon, this review has enabled us to work closely with the different stakeholders to offer a care plan for acute paediatric ischaemic stroke. Nevertheless, prospective national registries would be valuable to continue improving the care provided to these patients.

Abstract
Ischemic stroke, a disease with high mortality and disability rate worldwide, currently has no effective treatment. The systemic inflammation response to the ischemic stroke, followed by immunosuppression in focal neurologic deficits and other inflammatory damage, reduces the circulating immune cell counts and multiorgan infectious complications such as intestinal and gut dysfunction dysbiosis. Evidence showed that microbiota dysbiosis plays a role in neuroinflammation and peripheral immune response after stroke, changing the lymphocyte populations. Multiple immune cells, including lymphocytes, engage in complex and dynamic immune responses in all stages of stroke and may be a pivotal moderator in the bidirectional immunomodulation between ischemic stroke and gut microbiota. This review discusses the role of lymphocytes and other immune cells, the immunological processes in the bidirectional immunomodulation between gut microbiota and ischemic stroke, and its potential as a therapeutic strategy for ischemic stroke.

Abstract
BACKGROUND Current studies on the impact of sex in the prognosis of childhood arterial ischemic stroke (AIS) are limited. We aimed to explore the sex differences in outcomes in patients with childhood AIS. METHODS A retrospective analysis was conducted using the prospective data from the Chinese Pediatric Ischemic Stroke Registry. Baseline characteristics between sexes were compared in the total population cohort, propensity score (PS)-matched cohort, and inverse probability of treatment weighting cohort. Multivariate logistic regression and ordinal regression were used to analyze the association of sex with outcomes. Mixed-effects regression model was applied to further analyze the improvement in pediatric modified Rankin Scale (mRS) scores between sexes from 90 days to one year. Survival analysis was used to estimate the recurrence rates during the follow-up period. RESULTS A total of 468 patients were finally included. Multivariate logistic regression showed that there were no significant differences between females and males in achieving favorable outcome (odds ratio [OR] 1.04, 95% confidence interval [CI] 0.63 to 1.72), functional independence (OR 0.98, 95% CI 0.59 to 1.63), or shift to worse pediatric mRS scores (OR 0.83, 95% CI 0.59 to 1.17) at 90-day. Mixed-effects regression and survival analysis indicated that females and males exhibited comparable functional recovery from 90 days to one year and had similar recurrent risk during the follow-up period. CONCLUSIONS This nationally-representative observational study indicated that both male and female pediatric patients with AIS exhibited comparable similar clinical outcomes at 90 days, as well as similar improvements and risks of recurrence during the follow-up period.

Abstract
BACKGROUND To analyze the clinical and neuroimaging features, risk factors, treatment choices, and long-term clinical outcomes in children with cerebral sinus venous thrombosis (CSVT). METHODS This is a retrospective cohort study of children diagnosed with CSVT between 2002 and 2018 at Texas Children's Hospital. RESULTS A total of 183 children (male: 62.3%) with CSVT were included. The average presenting age was 7.7 years (S.D.: 5.6). The mean follow-up duration was 33.7 months (S.D.: 38.6). The most common presenting clinical feature was headache (36.6%). Head and neck infections other than meningitis (36.6%) were the most common risk factors. Prevalent neurological examination findings included motor deficit (21.3%) and altered mental status (AMS, 20.2%). Neuroimaging features included hemorrhagic infarction (19.6%), ischemic infarction (8.2%), and intracranial hemorrhage without infarction (5.5%). The most common site of thrombosis was the superior sagittal sinus (37.2%), with 78.2% of patients demonstrating involvement of multiple sinuses. Treatment of choice was low-molecular-weight heparin in 69.4% of patients. Factors associated with worse clinical outcomes included head and neck infections, malignancy (other than hematologic), cardiac disease, and recent surgery; seizure and dehydration on initial presentation; motor abnormalities and AMS on initial examination; ischemic infarct only; and involvement of vein of Trolard on neuroimaging. Thrombus condition on repeat imaging, receiving any anticoagulant/antithrombotic treatment, treatment duration, or follow-up duration was not associated with severity of long-term outcome. CONCLUSIONS CSVT may lead to unfavorable long-term outcomes in a remarkable portion of pediatric patients. Thus, a high index of suspicion and early and appropriate management of pediatric CSVT is imperative.

Abstract
Childhood arterial ischaemic stroke (AIS) is a significant health concern with increasing incidence. This review aims to provide an overview of the current understanding of childhood AIS. The incidence of childhood AIS is on the rise especially in developing countries, likely due to improved awareness and diagnostic capabilities. Aetiology of childhood AIS is multifactorial, with both modifiable risk factors and genetic predisposition playing important roles. Identifying and addressing these risk factors, such as infection, sickle cell disease, and congenital heart defects, is essential in prevention and management. Identifying underlying conditions through genetic testing is important for appropriate management and long-term prognosis. Clinically, distinguishing stroke from stroke mimics can be challenging. Awareness of important stroke mimics, including migraines, seizures, and metabolic disorders, is crucial to avoid misdiagnosis and ensure appropriate treatment. The diagnostic approach to childhood AIS involves a comprehensive "chain of care," including initial assessment, neuroimaging, and laboratory investigations. National guidelines play a pivotal role in standardizing and streamlining the diagnostic process, ensuring prompt and accurate management. Early intervention is critical in the management of childhood AIS. Due to the critical time window, the question if mechanical thrombectomy is feasible and beneficial should be addressed as fast as possible. Early initiation of antiplatelet or anticoagulation therapy and, in select cases, thrombolysis can help restore blood flow and minimize long-term neurological damage. Additionally, rehabilitation should start as soon as possible to optimize recovery and improve functional outcomes. In conclusion, childhood AIS is a growing concern. Understanding the increasing incidence, age distribution, risk factors, clinical presentation, diagnostic approach, and management strategies is crucial for optimized management of these patients.

Abstract
Neurological diseases and neurotrauma manifest significant sex differences in prevalence, progression, outcome, and therapeutic responses. Genetic predisposition, sex hormones, inflammation, and environmental exposures are among many physiological and pathological factors that impact the sex disparity in neurological diseases. MicroRNAs (miRNAs) are a powerful class of gene expression regulator that are extensively involved in mediating biological pathways. Emerging evidence demonstrates that miRNAs play a crucial role in the sex dimorphism observed in various human diseases, including neurological diseases. Understanding the sex differences in miRNA expression and response is believed to have important implications for assessing the risk of neurological disease, defining therapeutic intervention strategies, and advancing both basic research and clinical investigations. However, there is limited research exploring the extent to which miRNAs contribute to the sex disparities observed in various neurological diseases. Here, we review the current state of knowledge related to the sexual dimorphism in miRNAs in neurological diseases and neurotrauma research. We also discuss how sex chromosomes may contribute to the miRNA sexual dimorphism phenomenon. We attempt to emphasize the significance of sexual dimorphism in miRNA biology in human diseases and to advocate a gender/sex-balanced science.

Abstract
Background Pediatric acquired brain injury (pABI) profoundly affects cognitive functions, encompassing IQ and executive functions (EFs). Particularly, young age at insult may lead to persistent and debilitating deficits, affecting daily-life functioning negatively. This study delves into the intricate interplay of age at insult, time post-insult, and their associations with IQ and EFs during chronic (>1 year) pABI. Additionally, we investigate cognitive performance across different levels of global function, recognizing the multifaceted nature of developmental factors influencing outcomes. Methods Drawing upon insult data and baseline information analyzing secondary outcomes from a multicenter RCT, including comprehensive medical and neuropsychological assessments of participants aged 10 to 17 years with pABI and parent-reported executive dysfunctions. The study examined associations between age at insult (early, EI; ≤7y vs. late, LI; > 7y) and time post-insult with IQ and EFs (updating, shifting, inhibition, and executive attention). Additionally, utilizing the Pediatric Glasgow Outcome Scale-Extended, we explored cognitive performance across levels of global functioning. Results Seventy-six participants, median 8 years at insult and 5 years post-insult, predominantly exhibiting moderate disability (n = 38), were included. Notably, participants with LI demonstrated superior IQ, executive attention, and shifting compared to EI, [adjusted mean differences with 95% Confidence Intervals (CIs); 7.9 (1.4, 14.4), 2.48 (0.71, 4.24) and 1.73 (0.03, 3.43), respectively]. Conversely, extended post-insult duration was associated with diminished performances, evident in mean differences with 95% CIs for IQ, updating, shifting, and executive attention compared to 1-2 years post-insult [-11.1 (-20.4, -1.7), -8.4 (-16.7, -0.1), -2.6 (-4.4, -0.7), -2.9 (-4.5, -1.2), -3.8 (-6.4, -1.3), -2.6 (-5.0, -0.3), and -3.2 (-5.7, -0.8)]. Global function exhibited a robust relationship with IQ and EFs. Conclusion Early insults and prolonged post-insult durations impose lasting tribulations in chronic pABI. While confirmation through larger studies is needed, these findings carry clinical implications, underscoring the importance of vigilance regarding early insults. Moreover, they dispel the notion that children fully recover from pABI; instead, they advocate equitable rehabilitation offerings for pABI, tailored to address cognitive functions, recognizing their pivotal role in achieving independence and participation in society. Incorporating disability screening in long-term follow-up assessments may prove beneficial.

Arterial Presumed Perinatal Ischemic Stroke: A Mini Review and Case Report of Cognitive and Speech-Language Profiles in a 5-Year-Old Girl. CHILDREN (BASEL, SWITZERLAND) 2023; 11:33. [PMID: 38255347 PMCID: PMC10814911 DOI: 10.3390/children11010033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/16/2023] [Accepted: 12/20/2023] [Indexed: 01/24/2024]
Abstract
Arterial presumed perinatal ischemic stroke is a type of perinatal stroke that emerges due to late or delayed diagnostics of perinatal or neonatal arterial ischemic stroke. It is usually recognized before one year of life due to hemiparesis. This injury may lead to cognitive, behavioral, or motor symptoms, and life-long neurodevelopmental disabilities. In this case report, we describe a five-year-old girl with a history of arterial presumed perinatal ischemic stroke in the left hemisphere, which adversely affected her cognitive and language outcomes. The girl's cognitive development has been uneven, ranging from below average to average, and she had specific language acquisition deficits in comprehension, vocabulary, morphology, use of complex syntax, and narrative structure. The obtained results point to the specificity of each child whose development is influenced not only by the timing of the brain lesion and the degree of damage, but also by the child's neurobiological capacity. In addition, we provide an updated review of the literature that includes information on epidemiology, risk factors, diagnostics, clinical manifestations, outcomes, and potential therapies. The present article highlights the importance of early intervention and systematic monitoring of children with perinatal stroke with the aim of improving the child's development.

Abstract
Ischemic stroke is a worldwide disease that seriously threatens human health, and there are few effective drugs to treat it. Dihydromyricetin (DHM) has anti-inflammatory, antioxidant, and antiapoptotic functions. We identified pyroptosis following ischemic stroke. Here, we investigated the effect of DHM on ischemic stroke and pyroptosis. In the first part of the experiment, Sprague-Dawley rats were randomly divided into the sham group and MCAO group. The MCAO model was established by occlusion of the middle cerebral artery for 90 min using a silica gel suture. The ischemic penumbra was used for mRNA sequencing 1 day after reperfusion. In the second part, rats were divided into the sham group, MCAO group, and DHM group. DHM was injected intraperitoneally at the same time as reperfusion starting 90 min after embolization for 7 consecutive days. The changes in pyroptosis were observed by morphological and molecular methods. The transcriptomics results suggested the presence of NLRP3-mediated pyroptotic death pathway activation after modeling. The Longa score was increased after MCAO and decreased after DHM treatment. 2,3,5-Triphenyltetrazolium chloride (TTC) staining showed that DHM could reduce the infarct volume induced by MCAO. Nissl staining showed disordered neuronal arrangement and few Nissl bodies in the MCAO group, but this effect was reversed by DHM treatment. Analysis of pyroptosis-related molecules showed that the MCAO group had serious pyroptosis, and DHM effectively reduced pyroptosis. Our results demonstrate that DHM has a neuroprotective effect on ischemic stroke that is at least partly achieved by reducing pyroptosis.

Pediatr Neurol 2023; 146:119-128. [PMID: 37480820 DOI: 10.1016/j.pediatrneurol.2023.06.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 04/16/2023] [Accepted: 06/19/2023] [Indexed: 07/24/2023]
Abstract
BACKGROUND We aimed to examine inherited thrombophilia frequencies by extending genetic profile to previously rarely or not investigated polymorphisms in children with ischemic pediatric stroke (IPS) and their parents. METHODS The study included 33 children: 23 with perinatal arterial ischemic stroke (PAIS), eight with childhood arterial ischemic stroke (CAIS), and two with sinovenous thrombosis and their parents (33 mother-child, 12 father-child, and 12 mother-father-child pairs). Genotyping of FV-Leiden, FV-H1299R, FII-G20210A, β-fibrinogen-455G>A, FXIII-A-Val34Leu, PAI-1(4G/5G), HPA-1, MTHFR-C677T, MTHFR-A1298C, ACE(I/D), and APOE(ε2-4) was performed using CVD Strip assay (ViennaLab, Austria). RESULTS At least one and up to seven simultaneously present polymorphisms were observed in all children with IPS, mothers, and fathers. More than five simultaneously present polymorphisms were identified threefold more frequently in children with IPS (10 of 33; 30%) compared with the child control group (17 of 150; 11%), yielding a statistically significant difference between the two groups (odds ratio [OR] = 3.40; 95% confidence interval [CI] = 1.39 to 8.35; P = 0.012). Stronger association was revealed for PAIS (OR = 4.17; 95% CI = 1.55 to 11.29; P = 0.008) and CAIS subgroups (OR = 7.82; 95% CI = 1.79 to 34.20; P = 0.012). Complete match of polymorphisms was not identified in any parent-child pair. A partial match (one to four mutual polymorphisms) was found in 11 of 12 parent-child pairs where until three mutual polymorphisms was present in 11 of 12 (91.7%) father-child compared with 21 of 33 (63.6%) mother-child pairs. CONCLUSIONS According to obtained results the simultaneous presence of more than five polymorphisms is associated with a higher risk for IPS occurrence, suggesting the risk enhancement for PAIS in the presence of pregnancy complications or for CAIS in conjunction with maternal comorbidity and positive family history. The presence of up to three mutual polymorphisms more frequently in father-child than mother-child pairs suggests significant paternal contribution of inherited thrombophilia to increased risk of IPS.

Abstract
Neonatal strokes constitute a major cause of pediatric mortality and morbidity. Neuroimaging helps in its diagnosis as well as prognostication. However, advanced imaging, including magnetic resonance imaging (MRI), carries multiple challenges. Limited data exists in the literature on imaging-based predictors of neurological outcomes in neonatal stroke in the Indian population. In this study, we reviewed our available data on neonatal stroke patients between 2015 and 2020 for clinico-radiological patterns. During this period, 17 neonatal strokes were admitted and the majority were term births with a slight male preponderance. Seizures and encephalopathy were the most common presentation. Multiple maternal risk factors such as gestational diabetes, meconium-stained liquor, APLA syndrome, fever, deranged coagulation profile, oligohydramnios, cord prolapse, and non-progressive labor were seen. Cardiac abnormalities were seen in only less than half of these patients with the most common finding being atrial septal defects (ASD). Transcranial ultrasound was performed in eight neonates and the pick-up rate of ultrasound was poor. MR imaging showed large infarcts in 11 patients. The MCA territory was most commonly involved. Interestingly, five neonates had venous thrombosis with three showing it in addition to arterial thrombosis. Associated ictal, as well as Wallerian changes, were noted in 10. Although large territorial infarcts were the most common pattern, non-contrast MR angiography did not show major vessel occlusion in these cases. Outcomes were fairly good and only three patients had a residual motor deficit at 1 year. No recurrence of stroke was seen in any of the neonates.

Abstract
Introduction Thrombotic events in neonates and children represent a rare although severe occurrence in view of the associated risk of mortality and sequelae. Quality evidence is limited in this field, and registry studies provide an essential base for research. The aim of this paper is to present the new Italian Registry of Infantile Thrombosis (RITI), set it into the scene of international thrombosis and stroke registries, and provide some insight on the challenges associated with registry management. Methods We present the detailed structure and content of the new RITI registry, a brief overview of its main data, and a reflection on its features, pitfalls and the main challenges related to its management. Results The RITI, initially started in 2007 and officially re-launched in 2017 after structural modifications, is a non-interventional retrospective and prospective registry study collecting data on neonatal and pediatric patients (0-18 years) who experienced a systemic or cerebral thrombotic event in Italy. The RITI is managed by a multidisciplinary team with expertise in pediatric thrombosis, and participation is open to all Italian physicians, on a voluntary basis. The overall aim of the registry is to acquire new evidence to better characterize the population of children with thrombotic events and improve their management and outcome. 48 Italian pediatric and intensive care units are actively involved in the RITI, including 85 medical doctors from 16 Italian regions. A total of 1,001 neonates and children affected by cerebral or systemic thrombosis have been enrolled. Discussion The RITI is one of the largest available European registries of neonatal and pediatric thrombosis. National registries like the RITI represent a model for the study of rare conditions based on multidisciplinary and multicenter collaboration, aimed at overcoming the limitations due to small populations of patients, and creating a network of experts for patient referral and continuous education. Moreover, registry studies have a pivotal role in the research on pediatric thrombosis, due to the limited feasibility of high-quality studies. In our experience, the main critical stages, pitfalls and challenges in registry management include adequate registry designing, diffusion, data completeness and quality control.

Abstract
AIM The aetiology of perinatal stroke is poorly understood. This study aimed to prospectively confirm the risk factors and identify any previously unknown variables. METHODS A prospective case-control study was conducted in Australia. Univariate odds ratios (ORs), associated 95% confidence intervals (CIs) and multivariable logistic regression models fitted with backwards stepwise variable selection were used. RESULTS Sixty perinatal stroke cases reported between 2017 and 2019 included 95% (57/60) with multiple risk factors. Univariate analysis identified emergency caesarean section rather than NVD (P < 0.01), low Apgar score (<7) at 1, 5 and 10 min of age (P < 0.01), resuscitation at birth (P < 0.01), abnormal cord blood gas (P < 0.01), neonatal infection/sepsis (P < 0.01), congenital heart disease (P < 0.01) and hypoglycaemia (P < 0.01) as significant risk factors. Multivariate analysis found smoking during pregnancy (OR: 1.48; 95% CI: 1.09-1.99), 1-min Apgar score < 7 (OR: 1.54; 95% CI: 1.15-2.08), 10-min Apgar score < 7 (OR: 1.26; 95% CI: 1.02-1.54) and hypoglycaemia (OR: 1.49; 95% CI: 1.07-2.06). CONCLUSIONS Perinatal stroke is associated with multiple risk factors. Exposure to smoking, 10-min Apgar score < 7, neonatal infection and hypoglycaemia were independent risk factors. Emergency caesarean section, resuscitation at birth and abnormal cord blood gas were additional risk factors.

Abstract
Objectives The study objective was to calculate the birth prevalence of perinatal stroke and examine risk factors in term infants. Some risk factors are present in healthy infants, making it difficult to determine at-risk infants. Study Design Prospective population-based perinatal stroke data were compared to the Australian general population data using chi-squared and Fisher's exact tests and multivariable logistic regression analysis. Results Sixty perinatal stroke cases were reported between 2017 and 2019. Estimated stroke prevalence was 9.6/100,000 live births/year including 5.8 for neonatal arterial ischemic stroke and 2.9 for neonatal hemorrhagic stroke. Eighty seven percent had multiple risk factors. Significant risk factors were cesarean section (p = 0.04), 5-min Apgar score <7 (p < 0.01), neonatal resuscitation (p < 0.01) and nulliparity (p < 0.01). Conclusions Statistically significant independent risk factors do not fully explain the cause of perinatal stroke, because they are not a direct causal pathway to stroke. These data now require validation in a case-control study.

Abstract
Epidemiological studies and clinical observations show evidence of sexual dimorphism in brain responses to several neurological conditions. It is suggested that sex-related differences between men and women may have profound effects on disease susceptibility, pathophysiology, and progression. Sexual differences of the brain are achieved through the complex interplay of several factors contributing to this phenomenon, such as sex hormones, as well as genetic and epigenetic differences. Despite recent advances, the precise link between these factors and brain disorders is incompletely understood. This review aims to briefly outline the most relevant aspects that differ between men and women in ischemia and neurodegenerative disorders (AD, PD, HD, ALS, and SM). Recognition of disparities between both sexes could aid the development of individual approaches to ameliorate or slow the progression of intractable disorders.

Abstract
Background Even though stroke is rare in children, it is associated with serious or life-threatening consequences. Despite its rarity, the occurrence of stroke in children has age-related differences in risk factors, etiopathogenesis, and clinical presentations. Unlike adults, who have arteriosclerosis as the major cause of stroke, risk factors for pediatric strokes are multiple, including cardiac disorders, infection, prothrombotic disorders, moyamoya disease, moyamoya syndrome, and others. The goal of the current study was to compare the characteristics, clinical features, etiology, subtypes, and workup of pediatric and adult strokes. Methods This was a hospital-based observational study conducted on 222 participants. All patients underwent a full clinical and neurological examination, full laboratory study, cardiac evaluation, and neuroimaging; CT scan, MRI, MRA, MRV, carotid duplex, and transcranial Doppler (TCD). Ischemic stroke (IS) etiology was classified according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria, the "proposed classification for subtypes of arterial ischemic stroke in children," and the Oxfordshire Community Stroke Project (OCSP). Stroke severity was determined by the National Institutes of Health Stroke Scale (NIHSS) and PedNIHSS on admission. Results The proportion of pediatric ischemic strokes in the current study was 63.4 percent, while hemorrhagic strokes were 36.5%. The majority of the adult patients had ischemic strokes (84.1%), while hemorrhagic strokes were noted in 15.8% of the patients. According to the original TOAST classification, in the current study, the etiology of pediatric IS was other determined causes in 63.6%, undetermined etiology in 27.2%, and cardioembolic in 9.0%. For the adult group, the major stroke subtypes were large artery disease, small vessel disease, cardioembolic, other determined causes, and undetermined etiology at 49.6%, 28.6%, 6.9%, 0.6%, and 12.5%, respectively. Conclusions There is a greater etiological role for non-atherosclerotic arteriopathies, coagulopathies, and hematological disorders in pediatric stroke, while adults have more atherothrombotic causes. The co-existence of multiple risk factors in pediatric ischemic stroke is noticed. Thrombophilia evaluation is helpful in every case of childhood stroke. Children who have had a stroke should undergo vascular imaging as soon as possible. Imaging modalities include TCD and Doppler ultrasound, CT, MRI, MRA, and MRV, and cerebral angiography.

Abstract
Abstract
Introduction Cerebral sinus venous thrombosis (CSVT) is a rare disease, especially in children. Therefore, thrombophilia markers, risk factors, treatment strategy, and MRI, as well as clinical outcome need further investigation to support future diagnostic and therapeutic guidelines for children.
Methods We retrospectively identified all children with CSVT treated in our center between January 1, 2000, and December 31, 2015. Risk factors and laboratory findings were investigated. Furthermore, outcome and treatment satisfaction were evaluated using magnetic resonance imaging (MRI) analyses and a modified questionnaire.
Results All 43 patients, who agreed to participate, were treated with therapeutic levels of heparin; 86% of children had an increased risk for thromboembolic events upon onset of CSVT (acute disease: 58.1%, perinatal risk factors: 9.3%, medical intervention/immobility: 14%, chronic disease: 16.3%). Thrombophilia markers showed positive results (e.g., reduced values for protein C/S, factor-V–Leiden mutation) in 58% of children at the time of CSVT diagnosis but dropping to 20.9% over the course of the disease. Forty-two of 43 patients received MRI follow-ups and the outcome showed complete recanalization in 69% of the patients and partial recanalization in 31%. At the onset of CSVT, 88% of patients reported restrictions in everyday life due to CSVT; at follow-up this percentage declined to 18%. Satisfaction with the outcome among parents/patients according to the questionnaire was high with 1.7 (German school grades from 1 to 6).
Conclusions All 42 children with MRI follow-up demonstrated complete or partial recanalization under anticoagulation. This positive result underlines the need for future studies on anticoagulation to optimize therapy regimens of pediatric CSVT.

Abstract
Background and purpose Stroke is associated with high disability and mortality rates and increases the incidence of organ-related complications. Research has revealed that the outcomes and prognosis of stroke are regulated by the state of the intestinal microbiota. However, the possibility that the manipulation of the intestinal microbiota can alter sex-related stroke outcomes remain unknown. Methods To verify the different effects of microbiota from different sexes on stroke outcomes, we performed mouse fecal microbiota transplantation (FMT) and established a model of ischemic stroke. Male and female mice received either male or female microbiota through FMT. Ischemic stroke was triggered by MCAO (middle cerebral artery occlusion), and sham surgery served as a control. Over the next few weeks, the mice underwent neurological evaluation and metabolite and inflammatory level detection, and we collected fecal samples for 16S ribosomal RNA analysis. Results We found that when the female mice were not treated with FMT, the microbiota (especially the Firmicutes-to-Bacteroidetes ratio) and the levels of three main metabolites tended to resemble those of male mice after experimental stroke, indicating that stroke can induce an ecological imbalance in the biological community. Through intragastric administration, the gut microbiota of male and female mice was altered to resemble that of the other sex. In general, in female mice after MCAO, the survival rate was increased, the infarct area was reduced, behavioral test performance was improved, the release of beneficial metabolites was promoted and the level of inflammation was mitigated. In contrast, mice that received male microbiota were much more hampered in terms of protection against brain damage and the recovery of neurological function. Conclusion A female-like biological community reduces the level of systemic proinflammatory cytokines after ischemic stroke. Poor stroke outcomes can be positively modulated following supplementation with female gut microbiota.

Abstract
Infants born prematurely have an increased risk of experiencing brain injury, specifically injury caused by Hypoxia Ischemia (HI). There is no approved treatment for preterm infants, in contrast to term infants that experience Hypoxic Ischemic Encephalopathy (HIE) and can be treated with hypothermia. Given this increased risk and lack of approved treatment, it is imperative to explore and model potential treatments in animal models of preterm injury. Hypothermia is one potential treatment, though cooling to current clinical standards has been found to be detrimental for preterm infants. However, mild hypothermia may prove useful. Caffeine is another treatment that is already used in preterm infants to treat apnea of prematurity, and has shown neuroprotective effects. Both of these treatments show sex differences in behavioral outcomes and neuroprotective effects, which are critical to explore when working to translate from animal to human. The effects and research history of hypothermia, caffeine and how sex affects these treatment outcomes will be explored further in this review article.

Abstract
Acquired brain injury (ABI) occurs commonly in young children. Despite this, the psychosocial implications of ABI in young children are not established, with little understood about the impacts on self-perception and self-esteem. In this study we investigated self-perception, self-esteem and behaviour of children with early ABI. Children with an ABI (n = 47) before six years were compared to 17 typically developing controls (TDCs) matched on demographics. Children were aged 6-12 years and completed the Harter Self-Perception Profile. One parent completed the Child Behavior Checklist. No differences for self-perception and self-esteem were found between the groups. Parents of children with an early ABI reported more internalizing and externalizing behaviours. Children with more externalizing behaviour and social skill problems had more negative self-perceptions. Interaction effects were seen between socioeconomic status (SES) and child self-perception and behaviour. Specifically, children from families of higher SES had a more positive perception of their appearance and children from lower SES backgrounds had more externalizing behaviours and social problems. The study suggests that the relationship between ABI and self-perception and self-esteem is complicated and that children with behavioural problems have lowered feelings of competence. SES has an important role in self-perception and behavioural outcomes.

Abstract
Importance The incidence and natural history of large vessel occlusion (LVO) stroke in children is largely unknown. These knowledge gaps limit the uptake of reperfusion therapies and reduce the efficiency of pediatric acute stroke pathways. Objective To determine the incidence and natural history of pediatric LVO stroke. Design, Setting, and Participants This retrospective population-based cohort study was conducted between January 2010 and December 2019, with a mean (SD) follow-up of 37.0 (28.8) months. Admissions from all pediatric hospitals in the state of New South Wales, Australia, with a final diagnosis of arterial ischemic stroke (AIS) in patients 1 month to younger than 17 years were included. A total of 85 of 251 identified cases were excluded based on selection criteria. Data were analyzed from July 2020 to June 2021. Exposures One-third of patients with LVO received mechanical thrombectomy with or without intravenous thrombolysis while the remainder were treated conservatively. Main Outcomes and Measures The primary outcome was the pediatric modified Rankin Scale (ped-mRS) score 3 months after stroke. Ordinal logistic regression was used to compare non-LVO, LVO without thrombectomy, and LVO with thrombectomy groups. Results Of 161 included patients, 56 (34.8%) were female, and the mean (SD) age was 6.1 (5.4) years. A total of 166 AIS admissions were studied, and clinical follow-up was available for 164 of 166 admissions. LVO was present in 39 admissions (23.5%). The incidence of LVO stroke was 0.24 per 100 000 patients per year (95% CI, 0.13-0.35). Patients with LVO who did not receive thrombectomy (n = 26) had poor neurological outcomes, with 19 (73.1%) experiencing moderate to severe disability or death (ped-mRS score of 3 to 6) at 3 months (6 of 12 patients receiving thrombectomy [50.0%]; 25 of 38 patients with LVO [65.8%]). Patients with LVO without thrombectomy had significantly worse clinical outcomes than patients with non-LVO at 3 months (odds ratio, 3.64; 95% CI, 1.68-7.87; P = .001). Most patients with LVO presented within time windows suitable for thrombectomy (27 of 39 [69.2%] within 6 hours; 35 of 39 [89.7%] within 24 hours). Conclusions and Relevance In this population-based cohort study, the natural history of pediatric patients with LVO stroke treated conservatively was poor, with most experiencing lifelong disability or death. Nearly 90% of pediatric patients with LVO presented within time windows suitable for thrombectomy.

Abstract
Stroke is an important cause of neurological morbidity in children; most survivors have permanent neurological deficits that affect the remainder of their life. Stroke in childhood, the focus of this Primer, is distinguished from perinatal stroke, defined as stroke before 29 days of age, because of its unique pathogenesis reflecting the maternal-fetal unit. Although approximately 15% of strokes in adults are haemorrhagic, half of incident strokes in children are haemorrhagic and half are ischaemic. The causes of childhood stroke are distinct from those in adults. Urgent brain imaging is essential to confirm the stroke diagnosis and guide decisions about hyperacute therapies. Secondary stroke prevention strongly depends on the underlying aetiology. While the past decade has seen substantial advances in paediatric stroke research, the quality of evidence for interventions, such as the rapid reperfusion therapies that have revolutionized arterial ischaemic stroke care in adults, remains low. Substantial time delays in diagnosis and treatment continue to challenge best possible care. Effective primary stroke prevention strategies in children with sickle cell disease represent a major success, yet barriers to implementation persist. The multidisciplinary members of the International Pediatric Stroke Organization are coordinating global efforts to tackle these challenges and improve the outcomes in children with cerebrovascular disease.

Abstract
OBJECTIVE To explore the etiology of infantile spasms (IS) in a large Chinese cohort based on the United States National Infantile Spasms Consortium (NISC) classification. METHODS In the present study, we recruited IS patients diagnosed at a single center (Xiangya Hospital, Central South University) between Jan 2010 and Aug 2019. Thereafter, we collected their clinical and genetic information retrospectively. Their underlying etiologies were classified according to the NISC classification and then compared in different scenarios to understand their distribution. RESULTS A total of 541 patients with IS from 18 provinces were included in this study. The underlying etiology was identified in 53.2% of the cases: structural-acquired, 25.3%; genetic, 12.9%; genetic-structural, 7.2%; structural-congenital, 5.0%; metabolic, 2.4%; infections, 0.4% and immune, 0%. Whole-exome sequencing (WES) provided the highest diagnostic yield (26.9%). In structural-acquired IS, the proportion of hypoglycemic brain injuries was significant, second only to hypoxic-ischemic encephalopathy. There was no patient discovered to have Down syndrome. STXBP1, CDKL5, TSC2, KCNQ2, IRF2BPL, and TSC1 were the most frequently implicated genes. Genetic causes were found to be the most common cause of IS in the early onset group, while structural-acquired etiologies were common in males and preterm babies. Patients with pre-spasm seizures were associated with a higher proportion of identified causes than those without. Non-acquired structural etiologies were more common in patients without hypsarrhythmia than in those with hypsarrhythmia. SIGNIFICANCE The most prevalent cause of IS was structural acquired followed by genetic causes. When brain MRI fails to detect the etiology, we propose WES as the next step. Structural-acquired IS and cases with genetic disorders are characteristic of the Chinese cohort, however, the etiology differs with the patient's age of onset, gestation age at birth, sex, and the presence/absence of both pre-spasm seizures, and hypsarrhythmia.

Abstract
This review provides an updated analysis of the main aspects involving the diagnosis and the management of children with acute ischemic stroke. Acute ischemic stroke is an emergency of rare occurrence in children (rate of incidence of 1/3500 live birth in newborns and 1-2/100,000 per year during childhood with peaks of incidence during the perinatal period, under the age of 5 and in adolescence). The management of ischemic stroke in the paediatric age is often challenging because of pleomorphic age-dependent risk factors and aetiologies, high frequency of subtle or atypical clinical presentation, and lacking evidence-based data about acute recanalization therapies. Each pediatric tertiary centre should activate adequate institutional protocols for the optimization of diagnostic work-up and treatments.Conclusion: The implementation of institutional standard operating procedures, summarizing the steps for the selection of candidate for neuroimaging among the ones presenting with acute neurological symptoms, may contribute to shorten the times for thrombolysis and/or endovascular treatments and to improve the long-term outcome. What is Known: •Acute ischemic stroke has a higher incidence in newborns than in older children (1/3500 live birth versus 1-2/100,000 per year). •Randomized clinical trial assessing safety and efficacy of thrombolysis and/or endovascular treatment were never performed in children What is New: •Recent studies evidenced a low risk (2.1% of the cases) of intracranial haemorrhages in children treated with thrombolysis. •A faster access to neuroimaging and hyper-acute therapies was associated with the implementation of institutional protocols for the emergency management of pediatric stroke.

Epidemiology, Clinical Features, and Outcome in a Cohort of Adolescents With Cerebral Venous Thrombosis. Neurology 2021; 97:e1920-e1932. [PMID: 34544816 DOI: 10.1212/wnl.0000000000012828] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 09/02/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND AND OBJECTIVES We aimed to analyze the epidemiologic, clinical, and paraclinical features of adolescents with cerebral venous thrombosis (CVT) and its therapeutic management and outcome. METHODS This multicenter retrospective cohort included patients 10 to 18 years of age hospitalized for a first episode of CVT in 2 French regions between 1999 and 2019. The number of cases was compared to the number recorded by the French health insurance system. The CVT registry of the Lariboisière hospital allowed comparisons with adults. RESULTS One hundred two patients were included (52.9% female; median age 15.1 years). Estimated incidence was 0.37 to 0.38 per 100,000 adolescents per year; 45.5% of patients presented with focal deficits or seizures or in a coma. Male patients were younger than female patients (14.2 vs 15.6 years; p < 0.01) and more often admitted to intensive care (52.1% vs 24.1%; p = 0.0,035). The lateral sinus was the most common CVT location (72.3%), and 29.4% of adolescents had associated venous infarction or hematoma. Most patients (94.1%) received anticoagulation. Treatment also included an endovascular procedure (2.9%), decompressive craniectomy (4.9%), and CSF shunt (6.9%). The most frequently identified CVT-associated condition was local infection in male (18.6%) and systemic disease in female (14.8%; p < 0.001) patients. The proportion of CVTs in adolescents without an identified associated condition or risk factor was low (1.9% vs 11.4% in adults; p < 0.002). Adverse outcome at 1 year was more frequent than in adults (33.3% vs 11.8%; p = 0.0,001). DISCUSSION CVT in adolescents is rare and complex with specific epidemiology, including differences in clinical presentation and associated conditions between sexes, and more severe outcomes than in adults. Careful specialized management and follow-up are therefore recommended.

Abstract
OBJECTIVE Focal cortical dysplasia (FCD) Type 1 and its three subtypes have yet not been fully characterized at the clinical, anatomopathological, and molecular level (International League Against Epilepsy [ILAE] FCD classification from 2011). We aimed to describe the clinical phenotype of patients with histopathologically confirmed FCD1A obtained from a single epilepsy center between 2002 and 2016. METHODS Medical records were retrieved from the hospital's archive. Results from electroencephalography (EEG) video recordings, neuroimaging, and histopathology were reevaluated. Magnetic resonance imaging (MRI) post-processing was retrospectively performed in nine patients. DNA methylation studies were carried out from archival surgical brain tissue in 11 patients. RESULTS Nineteen children with a histopathological diagnosis of FCD1A were included. The average onset of epilepsy was 0.9 years (range 0.2-10 years). All children had severe cognitive impairment and one third had mild motor deficits, yet fine finger movements were preserved in all patients. All patients had daily seizures, being drug resistant from disease onset. Interictal electroencephalography revealed bilateral multi-regional epileptiform discharges. Interictal status epilepticus was observed in 8 and countless subclinical seizures in 11 patients. Regional continuous irregular slow waves were of higher lateralizing and localizing yield than spikes. Posterior background rhythms were normal in 16 of 19 children. Neuroimaging showed unilateral multilobar hypoplasia and increased T2-FLAIR signals of the white matter in 18 of 19 patients. All children underwent tailored multilobar resections, with seizure freedom achieved in 47% (Engel class I). There was no case with frontal involvement without involvement of the posterior quadrant by MRI and histopathology. DNA methylation profiling distinguished FCD1A samples from all other epilepsy specimens and controls. SIGNIFICANCE We identified a cohort of young children with drug resistance from seizure onset, bad EEG with posterior emphasis, lack of any focal neurological deficits but severe cognitive impairment, subtle hypoplasia of the epileptogenic area on MRI, and histopathologically defined and molecularly confirmed by DNA methylation analysis as FCD ILAE Type 1A.

Abstract
Stroke disrupts the homeostatic balance within the brain and is associated with a significant accumulation of necrotic cellular debris, fluid, and peripheral immune cells in the central nervous system (CNS). Additionally, cells, antigens, and other factors exit the brain into the periphery via damaged blood–brain barrier cells, glymphatic transport mechanisms, and lymphatic vessels, which dramatically influence the systemic immune response and lead to complex neuroimmune communication. As a result, the immunological response after stroke is a highly dynamic event that involves communication between multiple organ systems and cell types, with significant consequences on not only the initial stroke tissue injury but long-term recovery in the CNS. In this review, we discuss the complex immunological and physiological interactions that occur after stroke with a focus on how the peripheral immune system and CNS communicate to regulate post-stroke brain homeostasis. First, we discuss the post-stroke immune cascade across different contexts as well as homeostatic regulation within the brain. Then, we focus on the lymphatic vessels surrounding the brain and their ability to coordinate both immune response and fluid homeostasis within the brain after stroke. Finally, we discuss how therapeutic manipulation of peripheral systems may provide new mechanisms to treat stroke injury.

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
OBJECTIVE To describe the etiology of childhood arterial-ischemic stroke from a developing country and assess short-term neurologic outcome. METHODS Prospective observational study. Consecutive children between the age of >28 days to <12 years, admitted with the diagnosis of arterial-ischemic stroke were enrolled during the study period from January 2017 to December 2018. Short-term neurologic outcome was assessed with Pediatric Cerebral Performance Category (PCPC) scale and Pediatric Stroke Outcome Measure (PSOM). RESULTS We enrolled 76 children with arterial-ischemic stroke, with a median age of 24 months (interquartile range 12-69), and 43 (57%) were boys. The most common risk factor for childhood arterial-ischemic stroke was arteriopathy in 59 (77%), followed by cardiovascular disorder in 12 (16%) children. Among 59 children with arteriopathy, 32 (42%) had infection-associated arteriopathies, 10 (13%) had mineralizing angiopathy, 10 (13%) had moyamoya disease. Pediatric stroke risk factors were classified according to Pediatric Stroke Classification and CASCADE primary classification. Short-term neurologic outcome was assessed at 3 months in 62 (82%) survivors. Among stroke survivors, 33 (61%) had sensory-motor deficits, and 24 (39%) had severe neurologic disability (PCPC ≥ 4). The presence of fever, encephalopathy, low Glasgow coma score at presentation, seizures, and infection-associated arteriopathy predicted severe neurologic disability at follow-up. CONCLUSION The risk factors for pediatric arterial-ischemic stroke are different from developed countries in our cohort. Infection-associated arteriopathies, mineralizing angiopathy, and moyamoya disease are the most common risk factors in our cohort. Two-thirds of pediatric stroke survivors have neurologic disability at short-term follow-up.

CHILD ABUSE & NEGLECT 2021; 117:105119. [PMID: 34023741 DOI: 10.1016/j.chiabu.2021.105119] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 04/23/2021] [Accepted: 05/11/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Cerebral sinovenous thrombosis (CSVT) is a postulated cause of subdural hemorrhage (SDH) that is hypothesized to mimic abusive head trauma (AHT). Minimal data exists directly investigating this relationship. OBJECTIVES To evaluate the frequency of SDH in children with CSVT, identify factors associated with CSVT and SDH, and to assess if any association supports the hypothesis that CSVT causes SDH. PARTICIPANTS AND SETTING The International Pediatric Stroke Study (IPSS) prospectively collects data on subjects birth to 19 years of age with intracranial thrombosis. METHODS IPSS subjects with CSVT and SDH were compared to those with CSVT and no SDH. For subjects with CSVT and SDH, neuroimaging reports further characterized the findings. In any case with no known risk factors for SDH, neuroimaging studies were reviewed by a pediatric neuroradiologist. RESULTS Of 216 subjects with CSVT, 20 (9.3%) had SDH. Those with SDH (median age 0.3 years) were younger than those without SDH (median age 4.2 years), p < 0.001. Subjects with CSVT and SDH more frequently had anoxia (OR = 10.8; 95% CI: 1.4, 81.1), head/neck injury (OR = 4.0; 95% CI: 1.3, 12.6), or abnormal consciousness (OR = 3.0; 95% CI: 1.2, 7.6). Of 20 subjects with CSVT and SDH, 19 had known risk factors for SDH. The remaining subject had a chronic SDH identified concomitantly to a newly symptomatic CSVT with accompanying venous infarctions. CONCLUSIONS SDH in the setting of CSVT is typically identified in children with independent risk factors for SDH. This study does not support the hypothesis that CSVT causes SDH.

Abstract
BACKGROUND AND PURPOSE Previous studies of stroke management and outcome in Sweden have revealed differences between men and women. We aimed to analyze if differences in stroke incidence, care, and outcome have altered over time. METHODS All stroke events registered in the Swedish Stroke Register 2005 to 2018 were included. Background variables and treatment were collected during the acute hospital stay. Survival data were obtained from the national cause of death register by individual linkage. We used unadjusted proportions and estimated age-adjusted marginal means, using a generalized linear model, to present outcome. RESULTS We identified 335 183 stroke events and a decreasing incidence in men and women 2005 to 2018. Men were on average younger than women (73.3 versus 78.1 years) at stroke onset. The age-adjusted proportion of reperfusion therapy 2005 to 2018 increased more rapidly in women than in men (2.3%-15.1% in men versus 1.4%-16.9% in women), but in 2018, women still had a lower probability of receiving thrombolysis within 30 minutes. Among patients with atrial fibrillation, oral anticoagulants at discharge increased more rapidly in women (31.2%-78.6% in men versus 26.7%-81.9% in women). Statins remained higher in men (36.9%-83.7% in men versus 32.3%-81.2% in women). Men had better functional outcome and survival after stroke. After adjustment for women's higher age, more severe strokes, and background characteristics, the absolute difference in functional outcome was <1% and survival did not differ. CONCLUSIONS Stroke incidence, care, and outcome show continuous improvements in Sweden, and previously reported differences between men and women become less evident. More severe strokes and older age in women at stroke onset are explanations to persisting differences.

Abstract
In developed countries, cerebrovascular diseases are among the 10 most common causes of death in both the pediatric and adult population. The prevalence of fatal outcomes following arterial ischemic stroke (AIS) in various groups of pediatric patients ranges from 1% to almost 32%. However, a constant improvement in stroke mortality among children has been observed. The extent of the decline differs among studies (from nearly tenfold to twofold decline), as it depends on the study population. While a portion of this variability might be explained by factors such as health care access, population age, diseases related to ethnicity, and different etiologies of stroke in studied populations, the understanding of such differences is still insufficient. Risk factors for death in the early stages of the disease are poorly understood and are usually based on the clinical presentations of relatively small groups of pediatric patients. Familiarity with these factors may be of significant importance for prognosis, but also for the early selection of patients requiring careful supervision. The present study aimed to analyze and discuss the current literature data on the incidence of early death and risk factors for early death in children suffering from stroke.

Assessment of Post-Stroke Consequences in Pediatric Ischemic Stroke in the Context of Neuroimaging Results-Experience from a Single Medical Center. CHILDREN-BASEL 2021; 8:children8040292.

Abstract
Arterial ischemic stroke (AIS) in children is a rare condition; its frequency is estimated at 0.58 to 7.9 new onsets in 100,000 children per year. The knowledge on risk factors, clinical outcomes and consequences of pediatric AIS is increasing. However, there are still many unknowns in the field. The aim of the study was to analyze the clinical presentation of pediatric AIS and its consequences according to the neuroimaging results and location of ischemia. The research was retrospective and observational. The analyzed group consisted of 75 AIS children (32 girls, 43 boys), whereby the age of the patients ranged from 9 months to 18 years at stroke onset. All the patients were diagnosed and treated in one tertiary center. The most frequent stroke subtype was total anterior circulation infarct (TACI) with most common ischemic focus location in temporal lobe and vascular pathology in middle cerebral artery (MCA). The location of ischemic focus in the brain correlated with post-stroke outcomes: intellectual delay and epilepsy, hemiparesis corresponded to the location of vascular pathology. A correlation found between ischemic lesion location and vascular pathology with post-stroke consequences in pediatric AIS may be important information and helpful in choosing proper early therapy. The expected results should lead to lesser severity of late post-stroke outcomes.

Abstract
PURPOSE The purpose of this study is to determine the frequency and radiological predictors of recurrent acute symptomatic seizures (RASS) and motor impairment at discharge after a neonatal arterial ischemic stroke (NAIS). METHODS In a nonconcurrent cohort study, 33 full-term newborns with NAIS confirmed by MRI are admitted into our hospital between January 2003 and December 2012. Stroke size, calculated as stroke volume divided by whole brain volume (WBV), was categorized as > or < 3.3% of WBV. A univariate analysis of categorical variables was performed using Fisher's exact test. A multivariate analysis was performed using logistic regression models including all variables with a p value < 0.1 in the univariate analysis. RESULTS The median age at NAIS was 2 days (IQR, 1-5.6), 36.4% were girls. The stroke size was > 3.3 of WBV in 48.5% of the cases, and 54.5% showed multifocal lesions. Involvement of the cerebral cortex (54.5%), thalamus (48.5%), posterior limb of the internal capsule (36.4%), basal ganglia (36.4%), and brainstem (28.2%) were found. At discharge, 45.5% of newborns had a motor deficit, and 27.3% had at least two seizures. Multivariate analyses revealed that stroke size > 3.3% of WBV (OR: 8.1, CI: 1.2-53.9) and basal ganglia involvement (OR: 12.8, CI: 1.7-95.4) predicted motor impairment at discharge. Cortical involvement of temporal and frontal lobes (OR: 14, CI: 2.2-88.1; and OR: 9.1, CI: 1.2-72.6) were predictive of RASS. CONCLUSION Stroke size and location are independent risk factors for adverse short-term neurological outcomes in full-term newborns following a NAIS.

Abstract
The male sex has been suggested to predominate in paediatric patients with arterial ischemic stroke (AIS), especially in newborns. The explanation for this phenomenon remains unsatisfactory since it focuses on the analysis of the potential relationship with trauma and arterial dissection. In turn, in some populations of young adults, men suffer from AIS more frequently than women, which may be related to the protective role of oestrogen. On the other hand, certain data indicate that women dominate over men. Some of the disparities in the frequencies of particular symptoms of AIS and poststroke consequences in both children and young adults have been suggested; however, data are scarce. Unfortunately, the low number of studies on the subject does not allow certain conclusions to be drawn. For adults, more data are available for patients aged over 60 years, the results of which are more obvious. The present literature review aimed to discuss available data on the prevalence of AIS, its clinical presentations, and poststroke consequences in regard to the sex of young patients. We considered young patients to be children from birth up to the age of 19 years of life and young adults to be individuals up to the age of 55 years. The role of sex hormones in AIS and possible gender differences in genetic risk factors for AIS were also discussed briefly.

Abstract
PURPOSE Cerebral venous thrombosis (CVT) is a rare disease in children, characterized by partial or total occlusion of blood flow in the cerebral venous system. The aim of this study is to describe clinical presentation, neuroimaging features, therapeutic management, and outcome of children with CVT. METHODS We retrospectively analyzed the data, including clinical manifestations, laboratory data, neurological findings, and treatment of children with radiologically confirmed CVT, admitted between January 2010 and March 2020 to our hospital. Cases of CVT complicating brain surgery were excluded. RESULTS We enrolled 24 children with CVT. Infection was the main etiology (58.3%), followed by trauma in 16.7% of cases. In the remaining 25% of cases, the cause was identified only in one patient presenting a thrombophilic factor. The most frequent site of thrombosis was the superficial venous system (86.8%), with multiple localizations disclosed in 79% of patients. All children received anticoagulant therapy with low molecular weight heparin (LMWH). One patient died for systemic complications of an underlying disease. No patient developed hemorrhagic events during the therapy, lasting from 35 to 360 days (mean 86 days). In all but one surviving patients (22 out of 24), recanalization of the sinus was observed at AngioMRI performed during follow-up. No neurological complications of CVT were recorded (mean follow-up: 1.5 year). CONCLUSIONS CVT may present with subtle and unspecific clinical manifestations in children. High level of suspicion should be kept in trauma and sinusitis. Anticoagulation treatment is safe and effective and should be promptly started to improve outcome.

Abstract
INTRODUCTION Various neurological complications may occur as a consequence of arterial ischemic stroke (AIS) and have an impact on daily activity of the patients, costs of their medical care and rehabilitation. The aim of this study was to analyze risk factors, stroke symptoms and post-stroke consequences in Polish pediatric patients depending on stroke subtype. MATERIAL AND METHODS We retrospectively reviewed 77 children under the age of 18 years following their first AIS. Patients were white, Polish Caucasians, recruited in the Department of Pediatric Neurology at the Medical University of Silesia in Katowice (Poland). Statistical analysis was performed using Statistica 12.0. RESULTS Gender differed significantly between stroke subgroups (p = 0.030). The presence of focal cerebral arteriopathy (FCA) and chronic diseases was associated with type of AIS (p = 0.003 and p = 0.050, respectively). An outcome without neurological deterioration (normal outcome) was observed in 43% of children with lacunar anterior circulation infarct (LACI). Hemiparesis was present in almost all children with total anterior circulation infarct (TACI), in two thirds of children with partial anterior circulation infarct (PACI) and in almost 50% of children with LACI or posterior circulation infarct (POCI). In every child with hemiplegia the stroke symptom evolved into hemiparesis at follow-up. Additionally, patients with a normal outcome were older at the time of AIS than those with at least one neurological consequence (OR = 0.894, p = 0.034). CONCLUSIONS The presence and number of neurological outcomes depend on stroke subtypes. A relation between the presence of post-stroke deficits and age at onset was observed. The odds of deficit after ischemic stroke decreases by an average of 10.6% if the child is 1 year older at the time of AIS.

Does the Occurrence of Particular Symptoms and Outcomes of Arterial Ischemic Stroke Depend on Sex in Pediatric Patients?-A Pilot Study. Brain Sci 2020; 10:brainsci10110881.

Abstract
Arterial ischemic stroke (AIS) in childhood is reported to occur more frequently in boys, which may lead to the assumption that the prevalence of post-stroke deficits is sex related. The present study aimed to evaluate sex-related differences in functional outcomes (hemiparesis, seizures, aphasia, and motor disturbances other than hemiparesis) in pediatric patients with AIS. A total of 89 children (52 boys and 37 girls; mean age at stroke onset: 8.4 ± 5.6 years) were evaluated retrospectively based on data from medical records. The patients were divided into subgroups according to age (i.e., infants and toddlers, children, and adolescents), stroke subtype (i.e., lacunar anterior circulation infarct (LACI), total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), posterior circulation infarct (POCI)) and stroke location (i.e., anterior stroke, posterior stroke). Significant differences in the prevalence of stroke subtypes between girls and boys were observed (p = 0.034). POCI stroke were found to be more frequent in boys than in girls (OR = 8.57 95%CI 1.05–70.23, p = 0.023). Males predominated in the total group and in all analyzed age subgroups. The proportions of boys within the subgroups according to stroke subtype were extremely high for the POCI and TACI stroke subgroups. On the other hand, girls predominated in the LACI stroke subgroup. Frequency of central type facial nerve palsy and other symptoms of AIS were found to significantly differ between male subgroups according to stroke subtype (p = 0.050 and p < 0.001, respectively), as well as between children with anterior stroke and those with posterior stroke (p = 0.059 and p < 0.001, respectively). Post-stroke seizures appeared significantly more commonly in girls with TACI and POCI stroke than in girls with LACI and PACI stroke (p = 0.022). In turn, the prevalence of post-stroke hemiparesis differed between stroke subtypes in boys (p = 0.026). In conclusion, sex may have an impact in predisposing to a certain type of AIS in the patient. Post-stroke seizure may be related to stroke subtype in girls and hemiparesis in boys. However, further studies are needed to confirm the results.

Abstract
Objective We aimed to analyze the differences in demographics, comorbidities, and the risk of in-hospital mortality in pediatric arterial ischemic stroke (PAIS) inpatient population by hematological (HEM) and cardiovascular (CV) risk factors. Methods A total of 4,036 inpatients (1-18 years of age) from the Nationwide Inpatient Sample (NIS) with a primary diagnosis of PAIS were included. Descriptive statistics, linear-by-linear association test, and logistic regression models were utilized to analyze differences in demographics, comorbidities, and their impact on mortality in PAIS inpatients by CV and HEM risk factors. Results The cumulative in-hospital mortality rate in the entire PAIS inpatient cohort was 3.6%. The mortality rate was higher in the CV cohort (57.4%) as compared to the HEM cohort (29.7%). When compared with the cohort with no risk factors, HEM and CV were associated with four times (95% CI: 2.36-8.03) and seven (95% CI: 4.03-12.61) times higher odds for in-hospital mortality respectively. CV risk factors like cardiomyopathy and diabetes, and HEM risk factors like blood disorders, coagulation disorders, and deficiency anemias were associated with a significantly increased risk of in-hospital mortality. Conclusion The in-hospital mortality risk in PAIS patients was increased by 613% by CV risk factors and by 336% by HEM risk factors. Early identification and effective management of associated CV and HEM risk factors in the PAIS patient population can pave the way for increased survival and improved clinical outcomes.

Abstract
BACKGROUND Bow hunter's syndrome, or occlusion of the vertebral artery with head rotation leading to ischemia and sometimes stroke, is rarely described in children. The authors review the literature and present a new case. METHODS Both OVID dating back to 1946 and PubMed records were reviewed using the terms ("Bow hunter syndrome" OR "bow hunter's") OR "rotational vertebral artery occlusion" combined with "child," and limited to English language. SCOPUS and the bibliographies of cases found in the search were used to identify additional articles. RESULTS Twelve articles were found describing 25 patients; there were 26 patients when combined with our case. Ages ranged from 1 to 18 years. Most (88.5%, 23/26) were male. Medical treatments included aspirin, clopidogrel, abciximab, enoxaparin, warfarin, and cervical collar. Stenting was tried in 2 cases but did not work long-term. Surgical treatments included decompression, cervical fusion, or a combination. We present a new case of a 12-year-old girl with recurrent stroke who had bilateral vascular compression only visible on provocative angiographic imaging with head turn. She was referred for cervical fusion, and abnormal ligamentous laxity was noted intraoperatively. CONCLUSIONS Bow hunter's syndrome is a rare but important cause of stroke since many of the patients experience recurrent strokes before the diagnosis is made. Reasons for the male predominance are unclear. Provocative angiography plays a key role in diagnosis, and both medical treatment and neurosurgical intervention may prevent recurrence.

[PMID: 32905840 DOI: 10.1016/j.neuroscience.2020.09.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 08/30/2020] [Accepted: 09/01/2020] [Indexed: 01/02/2023]
Abstract
Neonatal hypoxic-ischemic encephalopathy is a major cause of mortality and disability in newborns and the only standard approach for treating this condition is therapeutic hypothermia, which shows some limitations. Thus, putative neuroprotective agents have been tested in animal models. The present study evaluated the administration of lactate, a potential energy substrate of the central nervous system (CNS) in an animal model of hypoxia-ischemia (HI), that mimics in neonatal rats the brain damage observed in human newborns. Seven-day-old (P7) male and female Wistar rats underwent permanent common right carotid occlusion combined with an exposition to a hypoxic atmosphere (8% oxygen) for 60 min. Animals were assigned to four experimental groups: HI, HI + LAC, SHAM, SHAM + LAC. Lactate was administered intraperitoneally 30 min and 2 h after hypoxia in HI + LAC and SHAM + LAC groups. HI and SHAM groups received vehicle at the same time points. The volume of brain lesion was evaluated in P9. Animals underwent behavioral assessments: negative geotaxis, righting reflex (P8 and P14), and cylinder test (P20). Lactate administration reduced the volume of brain lesion and improved behavioral parameters after HI in both sexes. Thus, lactate administration could be a neuroprotective strategy for the treatment of neonatal HI, a disorder still affecting a significant percentage of human newborns.

Abstract
OBJECTIVE To describe a pediatric stroke syndrome with chronic focal vertebral arteriopathy adjacent to cervical abnormalities. METHODS At a single pediatric stroke center, we identified consecutive children with stroke and vertebral arteriopathy of the V3 segment with adjacent cervical bony or soft tissue abnormalities. We abstracted clinical presentation, treatment, and follow-up data from medical charts. RESULTS From 2005 to 2019, 10 children (all boys, ages 6-16 years) presented with posterior circulation strokes and vertebral arteriopathy with adjacent cervical pathology. Two children had bony abnormalities: one had a congenital arcuate foramen and one had os odontoideum with cervical instability. In children without bony pathology, vertebral artery narrowing during contralateral head rotation was visualized by digital subtraction angiography. Eight boys had recurrent ischemic events despite anti-thrombotic treatment (including 5 with multiple recurrences) and were treated surgically to prevent additional stroke. Procedures included vertebral artery decompression (n = 6), endovascular stent and spinal fusion (n = 1), and vertebral artery endovascular occlusion (n = 1). In boys treated with decompression, cervical soft tissue abnormalities (ruptured atlantoaxial bursa, ruptured joint capsule, or connective tissue scarring) were directly visualized during open surgery. No other etiology for stroke or dissection was found in any of the cases. Two boys without recurrent stroke were treated with activity restriction and antithrombotics. At a median follow-up of 51 months (range 17-84), there have been no additional recurrences. CONCLUSIONS Children with V3 segmental vertebral arteriopathy frequently have stroke recurrence despite antithrombotics. Cervical bone imaging and angiography with neck rotation can identify underlying pathology.

Abstract
OBJECTIVE To determine that children with arterial ischemic stroke (AIS) due to an identifiable arteriopathy are distinct from those without arteriopathy and that each arteriopathy subtype has unique and recognizable clinical features. METHODS We report a large, observational, multicenter cohort of children with AIS, age 1 month to 18 years, enrolled in the International Pediatric Stroke Study from 2003 to 2014. Clinical and demographic differences were compared by use of the Fisher exact test, with linear step-up permutation min-p adjustment for multiple comparisons. Exploratory analyses were conducted to evaluate differences between cases of AIS with and without arteriopathy and between arteriopathy subtypes. RESULTS Of 2,127 children with AIS, 725 (34%) had arteriopathy (median age 7.45 years). Arteriopathy subtypes included dissection (27%), moyamoya (24.5%), focal cerebral arteriopathy-inflammatory subtype (FCA-i; 15%), diffuse cerebral vasculitis (15%), and nonspecific arteriopathy (18.5%). Children with arteriopathic AIS were more likely to present between 6 and 9 years of age (odds ratio [OR] 1.93, p = 0.029) with headache (OR 1.55, p = 0.023), multiple infarctions (OR 2.05, p < 0.001), sickle cell anemia (OR 2.9, p = 0.007), and head/neck trauma (OR 1.93, p = 0.018). Antithrombotic use and stroke recurrence were higher in children with arteriopathy. Among arteriopathy subtypes, dissection was associated with male sex, older age, headache, and anticoagulant use; FCA-i was associated with hemiparesis and single infarcts; moyamoya was associated with seizures and recurrent strokes; and vasculitis was associated with bilateral infarctions. CONCLUSION Specific clinical profiles are associated with cerebral arteriopathies in children with AIS. These observations may be helpful indicators in guiding early diagnosis and defining subgroups who may benefit most from future therapeutic trials.

Abstract
Stroke is an uncommon but an important and under-recognized cause of morbidity and mortality in children. Strokes may be due to either brain ischemia or intracranial hemorrhage. Common symptoms of pediatric acute stroke include headache, vomiting, focal weakness, numbness, visual disturbance, seizures, and altered consciousness. Most children presenting with an acute neurologic deficit do not have an acute stroke, but have symptoms due to stroke mimics which include complicated migraine, seizures with postictal paralysis, and Bell palsy. Because of frequency of stroke mimics, in children and the common lack of specificity in symptoms, the diagnosis of a true stroke may be delayed. There are a relatively large number of potential causes of stroke mimic and true stroke. Consequently, imaging plays a critical role in the assessment of children with possible stroke and especially in children who present with acute onset of stroke symptoms. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Neurology 2020; 94:e1259-e1270. [DOI: 10.1212/wnl.0000000000009136] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 11/05/2019] [Indexed: 11/15/2022] Open
Abstract
ObjectiveTo test the hypothesis that the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is useful in determining outcomes after neonatal arterial ischemic stroke (NAIS), we assessed accuracy of the modified pediatric ASPECTS (pedASPECTS) to predict cerebral palsy (CP), neurologic impairment, and epilepsy.MethodsCross-sectional study included newborns with acute NAIS whose outcomes were assessed at ≥18 months after stroke. PedASPECTS accuracy to predict outcomes was determined by sensitivity, specificity, and receiver operator characteristic (ROC) curves, and correlation between pedASPECTS and infarct volume was determined by the Spearman correlation coefficient.ResultsNinety-six children met the inclusion criteria. Median percentage infarct to supratentorial brain volume was 6.8% (interquartile range [IQR] 3.0%–14.3%). Median pedASPECTS was 7 (IQR 4–10). At a median age of 2.1 years, 35% developed CP, 43% had neurologic impairment, and 7% had epilepsy. Median pedASPECTS predicted outcomes of interest: CP (10, IQR 8–12) vs no CP (5, IQR 4–8) (p < 0.0001), poor (9, IQR 7–12) vs good (6, IQR 4–8) neurologic outcomes (p < 0.0001), and epilepsy (10, IQR 8–12) vs no epilepsy (7, IQR 4–10) (p = 0.033). PedASPECTS accuracy was good for CP (ROC 0.811) and fair for neurologic impairment (ROC 0.760) and epilepsy (ROC 0.761). A pedASPECTS ≥8 had ≥69% sensitivity and ≥54% specificity for clinical outcomes. PedASPECTS correlated with infarct volume (Spearman rank 0.701, p < 0.0001).ConclusionsThis study provides Class II evidence that pedASPECTS has fair to good accuracy for predicting CP, neurologic impairment, and epilepsy after NAIS and correlates with infarct volume. PedASPECTS may assist with early identification of babies requiring close developmental surveillance.
