Abstract
Neutrophil extracellular traps are primarily composed of DNA and histones and are released by neutrophils to promote inflammation and thrombosis when stimulated by various inflammatory reactions. Neutrophil extracellular trap formation occurs through lytic and non-lytic pathways that can be further classified by formation mechanisms. Histones, von Willebrand factor, fibrin, and many other factors participate in the interplay between inflammation and thrombosis. Neuro-immunothrombosis summarizes the intricate interplay between inflammation and thrombosis during neural development and the pathogenesis of neurological diseases, providing cutting-edge insights into post-neurotrauma thrombotic events. The blood-brain barrier defends the brain and spinal cord against external assaults, and neutrophil extracellular trap involvement in blood-brain barrier disruption and immunothrombosis contributes substantially to secondary injuries in neurological diseases. Further research is needed to understand how neutrophil extracellular traps promote blood-brain barrier disruption and immunothrombosis, but recent studies have demonstrated that neutrophil extracellular traps play a crucial role in immunothrombosis, and identified modulators of neuro-immunothrombosis. However, these neurological diseases occur in blood vessels, and the mechanisms are unclear by which neutrophil extracellular traps penetrate the blood-brain barrier to participate in immunothrombosis in traumatic brain injury. This review discusses the role of neutrophil extracellular traps in neuro-immunothrombosis and explores potential therapeutic interventions to modulate neutrophil extracellular traps that may reduce immunothrombosis and improve traumatic brain injury outcomes.

Abstract
PURPOSE Cerebral venous sinus thrombosis (CVST) is a rare but life-threatening event with significant neurologic and visual morbidity. In this study, we report on the natural history and visual outcomes of papilledema in children with CVST. DESIGN Retrospective case series. METHODS Patients with CVST evaluated by the Department of Ophthalmology between 2000 and 2023 were included. Records were reviewed for presence and course of papilledema, treatment, and final visual outcomes following papilledema resolution. RESULTS The study included 35 patients with a mean age of 9 ± 5 years and 40% were female. The most common risk factors for CVST were infection (69%), dehydration (26%), and hypercoagulability (23%). 31 patients (89%) had papilledema. Of these patients, 9 (29%) had progression of papilledema despite treatment, 17 patients (55%) did not have progression, and 5 patients (16%) lacked follow-up records. Initial Frisén grade among all cases was 2 ± 1, and cases with progression reached a grade of 4 ± 1 between 10 and 32 days following initial identification. Most patients (97%) were treated with anticoagulation and 100% required acetazolamide and/or lumbar puncture. Among 26 patients with follow-up, papilledema resolved in 107 ± 128 days. Fifty-four percent of patients had permanent ophthalmic sequelae. An initial Frisén grade ≥3 (odds ratio 7.54, 95% confidence interval 6.53-8.70, P< .001) was significantly associated with eventual optic atrophy. CONCLUSIONS Children with CVST are at high risk for ophthalmologic sequelae. Papilledema can progress despite appropriate therapy. Our results highlight the importance of ophthalmologic follow-up during treatment course to prevent irreversible vision loss.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare type of stroke indicated by the formation of blood clots within the dural venous sinuses. These are large venous conduits that are situated between the 2 layers of the dura mater which are responsible for draining blood from the brain and returning it to the systemic circulation. Cortical venous thrombosis refers to the blockage of veins on the brain's cortical surface. Cerebral venous thrombosis encompasses both dural and cortical vein occlusions.

Abstract
This case report discusses the intricate diagnostic and therapeutic challenges faced by a 23-year-old Indian male who presented with altered consciousness, a holo-cranial headache, right-sided hemiparesis, and subsequent neurological symptoms. The patient's dietary habits, leading to vitamin B12 and folic acid deficiencies resulting in hyperhomocysteinemia, along with binge alcohol drinking leading to dehydration, were identified as the main causes of cerebral venous sinus thrombosis (CVST) in this case. The case was complicated by an additional cerebral hemorrhage. The patient received a comprehensive treatment regimen involving antiepileptic medications, intravenous fluids, and anticoagulation therapy. A decline in the Glasgow Coma Scale score prompted further interventions. Collaborative decision-making, involving neurologists, neurosurgeons, and the patient's relatives, steered the treatment course, ultimately favoring continued medical management over decompression surgery. Notably, the patient exhibited remarkable progress in mobility, achieving the ability to walk with support by the end. This case report contributes valuable insights to the understanding of CVST, emphasizing the significance of nutritional considerations, especially in vegetarians, and underscoring the importance of thorough diagnostic evaluations in complex clinical scenarios.

Abstract
Lumbar puncture (LP) is rarely complicated by cerebral vein thrombosis (CVT), especially if other risk factors coexist. We describe the case of a 28-year-old woman who developed CVT after corticosteroid treatment and LP performed for suspected multiple sclerosis. The day after LP, she developed intense headache and on Day 8 generalized tonic-clonic seizures. A brain computed tomography scan showed thrombosis of the superior sagittal sinus and cortical veins. Thrombophilia screening showed heterozygous G20210A prothrombin mutation. Anticoagulant therapy with low molecular weight heparin and then warfarin was administered until Day 16 after LP, when a brain magnetic resonance imaging showed a subdural hematoma. Warfarin was interrupted and dabigatran was started. The patient recovered completely, both from the initial thrombotic event and the hemorrhagic complication. This case highlights the importance to keep in mind CVT in the differential diagnosis of post-LP headache not responsive to standard therapy, and suggests that dabigatran can be considered an effective and safe treatment of CVT.

Abstract
BACKGROUND Cerebral Venous Sinus Thrombosis (CVST) is a rare but potentially life-threatening condition, often associated with specific risk factors. The primary treatment for CVST is anticoagulation, but some cases progress to Refractory CVST (rCVST), requiring endovascular treatment. A combination of stent retriever and catheter aspiration is emerging as a promising technique to enhance treatment effectiveness. We conducted a systematic review and meta-analysis to assess the safety and efficacy of this approach, aiming to improve recanalization success and neurological outcomes while reducing complications in rCVST patients. METHODS A search following PRISMA guidelines was conducted across Pubmed, Embase, Web of Science, and Cochrane databases to identify studies on the use of stent retrievers and catheter aspiration for rCVST. Pooled analysis with 95 % confidence intervals was used to assess the effects. Heterogeneity was evaluated using I2 statistics and a random-effects model was used. Complete recanalization. good clinical outcomes (mRS ≤ 2), hemorrhagic, neurological, ischemic, and total complications, poor clinical outcomes (mRS > 2), and mortality were assessed. RESULTS A meta-analysis of five retrospective studies involving 55 patients examined outcomes in CVST. The median mean age was 40 years. Complete recanalization rate: 36 % (95 % CI: 9 % to 62 %, I2 = 90 %). Good clinical outcomes: 72 % (95 % CI: 50 % to 94 %, I2 = 76 %). Hemorrhagic complications: 2 % (95 % CI: 0 % to 8 %, I2 = 15 %). Ischemic complications: 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Neurological complications: 7 % (95 % CI: 0 % to 14 %, I2 = 0 %). Poor clinical outcomes: 26 % (95 % CI: 6 % to 46 %, I2 = 70 %). Total complications: 6 % (95 % CI: 0 % to 15 %, I2 = 10 %). Mortality rate: 5 % (95 % CI: 0 % to 13 %, I2 = 19 %). CONCLUSION This systematic review and meta-analysis scrutinized the efficacy of combining Stent Retriever and Catheter Aspiration for rCVST. Findings highlighted varied outcomes, including recanalization rates, complications, and mortality. The dichotomy between good and poor outcomes underscores the necessity for personalized therapeutic decisions. While offering a comprehensive overview, the study emphasizes literature heterogeneity, suggesting a need for more rigorous and standardized research to optimize therapeutic strategies in clinical practice.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare neurovascular condition that has been observed in individuals with coronavirus disease 2019 (COVID-19). This systematic review aimed to explore the sex differences and characteristics of concurrent COVID-19 and CVST cases. A total of 212 CVST patients were included in the study. Women with CVST had a slightly higher mean age compared to men (47.359 years vs 46.08 years). Women were more likely to report symptoms such as fever (56.1%) and decreased sense of smell or taste (71.4%), while men more frequently experienced nausea or vomiting (55.6%), headache (62.9%), and seizures (72%). Notably, current smokers, who were predominantly men, had a higher occurrence of CVST. On the other hand, women had a higher likelihood of CVST risk factors such as oral contraceptive pill (OCP) use and autoimmune diseases. Treatment approaches also showed sex-based differences. Unfractionated heparin was administered more often to women with CVST (63.2%). The in-hospital mortality rate for CVST patients was 21.3%, with men having a significantly higher mortality rate than women (65.2% vs 34.8%, P = .027). Survival analysis revealed that factors such as smoking history, diabetes mellitus, hypertension, OCP use, COVID-19 symptoms, CVST symptoms, and the need for intubation significantly influenced survival outcomes. Understanding these sex differences in COVID-19-related CVST is crucial for accurate diagnosis and effective management, ultimately leading to improved patient outcomes. Our findings highlight the importance of considering sex as a factor in the evaluation and treatment of individuals with COVID-19 and concurrent CVST.

Abstract
BACKGROUND The multi-inflammatory index (MII) is a novel marker that indicates the diagnosis, prognosis, and clinical severeness of inflammation-associated diseases. It is indicated that inflammatory biomarkers may help predict the occurrence of acute symptomatic seizures(ASS) after ischemic stroke. OBJECTIVE Our goal was to search the predictive and prognostic capability of the MII-1 and MII-2 for ASS in cerebral venous sinus thrombosis (CVST) patients. METHOD 91 patients with CVST were retrospectively analyzed from the medical records of patients between 2010 and 2023 and divided into the ASS group and non-ASS group. The MII-1 and MII-2 levels on admission, demographic and clinic features, predisposing risk factors, radiological characteristics involving thrombotic cerebral veins, and the type of parenchymal lesions were documented. Modified Rankin Scale (mRS) on admission and at the 3rd month were evaluated to determine the disability. RESULTS MII-1 and MII-2 were statistically significantly higher in the ASS group and predictors for the occurrence of seizures with CVST in multivariate analysis. The area under the curve (AUC) of the receiver operating characteristics (ROC) curve for MII-1 was 0.791 (95 %CI = 0.691-0.891, p < 0.001), and AUC for MII-2 was 0.761 (95%CI = 0.660-0.861, p < 0.001). When the clinical variables that were included in the multivariate analysis and MII-1 and MII-2 were combined, the predictive power was greater with the AUC of 0.959. A significant positive correlation was found between mRS at the 3rd month and MII-1 and MII-2 in the ASS group. CONCLUSION MII-1 and MII-2 can be used as new predictive and prognostic markers of ASS in patients with CVST.

Abstract
OBJECTIVES Cerebral venous sinus thrombosis (CVST) can cause sinus obstruction and stenosis, with potentially fatal consequences. High-resolution magnetic resonance imaging (HRMRI) can diagnose CVST qualitatively, although quantitative screening methods are lacking for patients refractory to anticoagulation therapy and who may benefit from endovascular treatment (EVT). Thus, in this study, we used radiomic features (RFs) extracted from HRMRI to build machine learning models to predict response to drug therapy and determine the appropriateness of EVT. MATERIALS AND METHODS RFs were extracted from three-dimensional T1-weighted motion-sensitized driven equilibrium (MSDE), T2-weighted MSDE, T1-contrast, and T1-contrast MSDE sequences to build radiomic signatures and support vector machine (SVM) models for predicting the efficacy of standard drug therapy and the necessity of EVT. RESULTS We retrospectively included 53 patients with CVST in a prospective cohort study, among whom 14 underwent EVT after standard drug therapy failed. Thirteen RFs were selected to construct the RF signature and CVST-SVM models. In the validation dataset, the sensitivity, specificity, and area under the curve performance for the RF signature model were 0.833, 0.937, and 0.977, respectively. The radiomic score was correlated with days from symptom onset, history of dyslipidemia, smoking, fibrin degradation product, and D-dimer levels. The sensitivity, specificity, and area under the curve for the CVST-SVM model in the validation set were 0.917, 0.969, and 0.992, respectively. CONCLUSIONS The CVST-SVM model trained with RFs extracted from HRMRI outperformed the RF signature model and could aid physicians in predicting patient responses to drug treatment and identifying those who may require EVT.

Abstract
Nephrotic syndrome (NS) is associated with cerebral venous sinus thrombosis (CVST), which is a rare cerebrovascular disorder in children. Systemic anticoagulation with heparin is the standard therapy for CVST, and mechanical thrombectomy (MT) has been described as a salvage treatment for adult anticoagulant refractory CVST, However, it has never been reported in children. We describe a case of MT for refractory CVST in a child with NS. A 13-year-old boy with newly diagnosed NS presented to an emergency department with acute headache. A head computed tomography showed acute thrombus in the superior sagittal sinus, straight sinus and transverse sinus. The child was started on heparin therapy, but clinically deteriorated and became unresponsive. In view of the rapid deterioration of the condition after anticoagulation treatment, the patient received intravascular treatment. Several endovascular technologies, such as stent retriever and large bore suction catheter have been adopted. After endovascular treatment, the patient's neurological condition was improved within 24 hours, and magnetic resonance venography of the head demonstrated that the CVST was reduced. The child recovered with normal neurological function at discharge. This case highlights the importance of considering MT for refractory CVST, and we suggest that MT may be considered for refractory CVST with NS in children.

Magn Reson Imaging 2023; 103:131-138. [PMID: 37481091 DOI: 10.1016/j.mri.2023.07.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 05/05/2023] [Accepted: 07/13/2023] [Indexed: 07/24/2023]
Abstract
PURPOSE To explore the feasibility of MR 3D T1w Sampling Perfection with Application optimized Contrasts by using different flip angle Evolutions (SPACE) sequence imaging in symptomatic CVT diagnose, extracting the imaging features with quantitative analysis. METHODS Fifty-nine patients with suspected CVT with neurological symptoms were retrospectively included in this study. Of them, 35 patients were enrolled in the comparation of diagnostic accuracy between the contrast-enhanced magnetic resonance venograms (CE-MRV) and 3D T1w SPACE imaging. Forty-five patients with 101 involved segments were identified for the quantitative analysis. All MR images were acquired on a 3.0 T MR scanner. The reference standard used in this study was a comprehensive combination of the imaging techniques and clinical information. CVT patients were grouped as acute (≤48 h), subacute (>48 h and ≤30d), and chronic (>30d) clinical phase. CVT segments were grouped based on pre-contrast T1WI, as type A: hypo intense signal; B: heterogeneously hyper intense signal; C: iso intense signal. The feasibility of 3D T1w SPACE imaging for diagnosing CVT was explored. Diagnostic accuracy of T1w SPACE imaging was analyzed and compared with the CE-MRV. The signal intensity of pre-contrast images (SpreCE), signal intensity of post-contrast images (SpostCE), and contrast enhancement (CE) rate, CE rate relative to that of pituitary gland (PG), white matter (WM), gray matter (GM), and normal vein vessel wall (nVVW) were compared based on both patients and segments. The CE rate grade of CVT segments of different imaging types was compared. RESULTS The MR 3D T1w SPACE imaging achieved a higher sensitivity and specificity (100%/94.1% and 100%/100% based on patients/segments separately) than that of the CE-MRV (73.9%/56.9% and 83.3%/98.9% based on patients/segments separately). No statistical correlation was found between the imaging types of CVT segments and onset time of clinical symptoms (χ2 = 6.649, P = 0.171). Quantitative analysis showed that the CE rate relative to PG and that to WM were higher in the chronic CVT patients than that in the other two groups (H = 10.330 and P = 0.006, H = 9.898 and P = 0.007, separately). CE rate relative to GM in the chronic group was higher than that in the subacute group (H = 7.143 and P = 0.028). All of the quantitative parameters were statistically different across CVT segments of three imaging types (all P≤0.001). CONCLUSION MR 3D T1w SPACE imaging has the advantage to accurately diagnose CVT of different clinical stages, and identify the involved thrombus segments.

Abstract
COVID-19 patients can exhibit a wide range of clinical manifestations affecting various organs and systems. Neurological symptoms have been reported in COVID-19 patients, both during the acute phase of the illness and in cases of long-term COVID. Moderate symptoms include ageusia, anosmia, altered mental status, and cognitive impairment, and in more severe cases can manifest as ischemic cerebrovascular disease and encephalitis. In this narrative review, we delve into the reported neurological symptoms associated with COVID-19, as well as the underlying mechanisms contributing to them. These mechanisms include direct damage to neurons, inflammation, oxidative stress, and protein misfolding. We further investigate the potential of small molecules from natural products to offer neuroprotection in models of neurodegenerative diseases. Through our analysis, we discovered that flavonoids, alkaloids, terpenoids, and other natural compounds exhibit neuroprotective effects by modulating signaling pathways known to be impacted by COVID-19. Some of these compounds also directly target SARS-CoV-2 viral replication. Therefore, molecules of natural origin show promise as potential agents to prevent or mitigate nervous system damage in COVID-19 patients. Further research and the evaluation of different stages of the disease are warranted to explore their potential benefits.

Abstract
Headache is one of the most common pain syndromes in the paediatric population. Headaches are classified as primary (migraine, tension-type headaches, trigeminal autonomic cephalalgia and other primary headaches) or secondary (e.g. post-traumatic). Non-febrile, non-traumatic headaches represent 1% of all paediatric emergency departments (PED) visits. Many patients present with an acute, moderate to severe pain, sometimes with a sudden onset. Sudden onset headache can be the main symptom of life-threatening neurological conditions as well as a sign of primary headaches such as thunderclap or stabbing headaches. This review aims to describe the presentation of sudden primary headaches in children, in order to help the physician to provide effective management in the emergency setting.

Abstract
Cerebral venous sinus thrombosis (CVST) usually presents with headaches, seizures, and signs and symptoms of raised intracranial pressure (ICP). Risk factors for CVST commonly include hypercoagulable states such as pregnancy and the peripartum period, dehydration, vitamin B12 deficiency, hyper-homocysteinemia, coagulation factor deficiency, antiphospholipid antibody disease, oral contraceptive pill intake, etc. CVST with venous hemorrhagic infarction is commonly reported, but only a few cases have been reported in the literature of CVST presenting as SDH. Here, we present a case of a 28-year-old female who presented with an acute onset of severe headache, vomiting, and bilateral papilledema on fundus examination. She had a prior history of oral contraceptive pill intake. An MRI brain venogram suggested CVST involving the superior sagittal sinus, right transverse, and a few cortical vein thromboses with subdural hematoma (SDH) in the frontal-parieto-temporo-occipital region on the right side. The patient was treated with anticoagulants and antiepileptics and had significant improvement in symptoms with the resolving SDH on subsequent scans.

Abstract
Cerebral venous thrombosis (CVT) is a rare entity that remains a diagnostic challenge due to various clinical manifestations and a wide variety of causative agents. Local infections, such as acute (AOM) or chronic otitis media, can play a role in the pathogenesis of CVT. The proximity of the tympanic cavity and temporal bone air cells to the dural venous sinuses predisposes them to secondary thrombosis. The release of inflammatory cytokines and activation of the coagulation pathway in the middle ear space in response to infection may trigger the thrombotic mechanism in venous sinuses of the central nervous system. There is no consensus in the literature concerning the treatment of otogenic cerebral venous sinus thrombosis (CVST). Both the extent of the surgery and the use of anticoagulants are disputable. The aim of the study was to provide a thorough analysis of the literature concerning CVST in patients with AOM and acute mastoiditis (AM). The current surgical and conventional treatment strategies are presented. Special attention has been attached to the predisposing factors, the extent of the surgery, and the role of anticoagulants in the treatment of septic otogenic CVST.

Abstract
Cerebral venous thrombosis (CVT) is a rare condition characterized by the obstruction of cerebral venous sinuses or cortical veins, leading to stroke-like symptoms. This case report presents a case of a 74-year-old male with isolated unilateral abducens nerve palsy as the sole sign of CVT, without accompanying symptoms or focal deficits. Neuroimaging, including CT and magnetic resonance venography, confirmed the diagnosis of CVT with a thrombus in the right transverse sinus. The patient was co-managed with the medical team and initiated on anticoagulation therapy. Follow-up showed resolution of diplopia and improvement in extraocular muscle movements. Unilateral abducens nerve palsy in CVT is rare, with most cases presenting as bilateral palsy. The case report emphasizes the importance of considering CVT in the differential diagnosis of isolated abducens nerve palsy and highlights the role of neuroimaging in early detection. Timely diagnosis and appropriate management are crucial for favorable outcomes in CVT cases. Further research is needed to enhance understanding of the pathophysiology, prognosis, and optimal management of this uncommon presentation.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare neurological emergency condition with non-specific symptoms. Imaging options to rule out CVST are computed tomography (CT) and magnetic resonance imaging (MRI). This study aimed to determine the imaging outcomes of emergency MRI as a first-line imaging method in patients with suspected CVST. In this retrospective cohort study, we analyzed emergency brain MRI referrals from a five-year period in a tertiary hospital for suspicion of CVST. We recorded patient characteristics, risk factors mentioned in the referrals, and imaging outcomes. Altogether 327 patients underwent emergency MRI on the grounds of suspected CVST. MRI showed evidence of CVST among five patients (1.5%). Imaging showed other clinically significant pathology in 15% of the patients and incidental findings in 5% of the patients. Despite clinical suspicion, the diagnostic yield of emergency MRI for CVST is low and similar to that previously reported for CT. MRI is an alternative imaging method devoid of ionizing radiation in patients with suspected CVST.

Abstract
Purpose The present study aimed to identify the characteristics, predictors, and imaging features of poor recovery in cases of cerebral venous sinus thrombosis (CVST). Patients and Methods A total of 290 consecutive adult patients with CVST were enrolled from January 2017 to December 2021 from five hospitals in Nanning, Guangxi. According to the modified Rankin scale (mRS) score at hospital discharge, the patients were classified into good prognosis (GP, mRS ≤2) groups and poor prognosis (PP, mRS>2) groups. Logistic regression was used to identify factors associated with clinical outcomes. Results Of the 290 patients, 35 were assigned to the PP group and 255 to the GP group. No significant difference in sex was observed between the two groups. Headache (76.21%) was the most frequent symptom of CVST, and local head and neck infection was the major comorbidity (26.21%). Approximately half of the patients (48.62%) had brain injury lesions <1 cm, and the most commonly affected sinus was the lateral sinus (81.03%). Less-common headaches (odds ratio [OR]: 2.769, p=0.046), altered mental status (OR: 0.122, p<0.001), hematologic disorder (OR: 0.191, p=0.045), and injury to multiple lobes (OR: 0.166, p=0.041) were associated with poor clinical outcomes. Conclusion Headache was the most common and protective manifestation of CVST, and disturbances in consciousness were an important indication of poor clinical prognosis. Patients with hematologic diseases also tended to have poor outcomes. No significant correlation was found between the number and location of venous sinus thromboses and clinical prognosis; however, intracranial injury involving multiple lobes was often associated with poor prognosis.

Abstract
Background: Cerebral venous sinus thrombosis (CVST) is a rare manifestation of thrombosis commonly caused by thrombophilia, hormonal-related factors, non-cerebral malignancy, and hematologic diseases. The aim of this review was to identify and summarize rare CVST cases. Methods: A literature search of the Medline database was performed in November 2022. CVST cases of a common cause were excluded. Demographic and clinical data were extracted. Eligible cases were categorized into inflammatory, primary CNS tumors, post-operative/traumatic, and idiopathic groups to allow statistical group comparisons. Results: 76 cases were analyzed. Idiopathic CVST was most frequently reported followed by inflammatory, post-traumatic/operative and primary CNS tumor causes. The intracranial hemorrhage rate was 23.7% and it was found to increase in the inflammatory group (45.8%). Anticoagulation was used in the majority of cases and it was significantly related to better outcomes. A low rate of anticoagulation use (43.8%) was found among CVST cases in the post-operative/traumatic group. The overall mortality rate was 9.8%. 82.4% of patients showed significant early improvement. Conclusions: Most rare CVST cases were either of idiopathic or inflammatory origin. Interestingly, hemorrhage occurred often he idiopathic CVST cases. A low rate of anticoagulation use in neurosurgical CVST cases after trauma or head surgery was observed.

Case report: cerebral venous sinus thrombosis and pulmonary embolism as the initial presentation in a child with asymptomatic primary nephrotic syndrome. Front Pediatr 2023; 11:1169116.

Abstract
Background Cerebral venous sinus thrombosis (CVST) is rare, but potentially life-threatening. The clinical course definitely become more unpredictable and fatal in patients complicated by pulmonary embolism (PE). Nephrotic syndrome (NS) is an uncommon etiology of CVST. Concurrence of CVST and PE at the initial onset of NS is extremely unusual and rarely reported. Considering that edema might be absent in NS individuals, thromboembolic events probably become unrecognized, thereby causing a missed or delayed diagnosis and poor outcome. Herein, we described an extraordinary case of an adolescent boy presenting with both CVST and PE initially just within 5 days of disease onset, who was ultimately diagnosed with asymptomatic NS, aiming to emphasize a high index of suspicion of these diseases in patients with conditions of hypercoagulability. Case presentation A 13-year-old male child presented acutely with dizziness, fever and dyspnea, with signs of shock but undetected edema. Initial laboratory investigations revealed hypoalbuminemia, typical images of pneumonia, and normal radiographic findings on non-enhanced computed tomography of head. Despite evidence of hypoalbuminemia and neurological symptoms, the child was still misdiagnosed as pneumonia. His dyspnea and period of headache deteriorated even if hemodynamic stability and undetected fever after initial therapy. The delayed urinalysis and 24-h urine examination both showed massive proteinuria. A computed tomography angiography of chest along with cranial magnetic resonance imaging/magnetic resonance venography were subsequently performed, consistent with the imaging features of PE and CVST, respectively. The diagnosis of asymptomatic primary NS complicated by PE and CVST was ultimately confirmed. The patient received corticosteroids and antithrombotic therapy with satisfactory results. Conclusion A persistent clinical suspicion of CVST should be borne in mind in patients with a sudden, new or worsening headache, specifically among those with prothrombotic conditions. NS should always be considered in the differential diagnosis of risk factors for CVST, even in absence of edema. Since CVST and PE can be present simultaneously at extraordinary early-onset of NS, early radiological diagnosis is clinically substantial to proper management and satisfactory long-term outcomes.

Abstract
Acute ischemic stroke (AIS) is a leading cause of morbidity worldwide and can present with nonspecific symptoms, making diagnosis difficult. Many neurologic diseases present similarly to stroke; stroke mimics account for up to half of all hospital admissions for stroke. Stroke therapies carry risk, so accurate diagnosis of AIS is crucial for prompt treatment and prevention of adverse outcomes for patients with stroke mimics. Computed tomography (CT) perfusion techniques have been used to distinguish between nonviable tissue and penumbra. RAPID is an operator-independent, automated CT perfusion imaging software that can aid clinicians in diagnosing strokes quickly and accurately. In this case-based review, we demonstrate the applications of RAPID in differentiating between strokes and stroke mimics.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare condition that can result in severe neurological complications when left untreated. Disease pathology results from thrombus development within the superficial cortical veins or the dural sinuses. Thrombosis impedes cerebral drainage leading to venous congestion and consequent increase in cerebral pressure, parenchymal damage, and blood-brain barrier disruption. Headache is the most common presenting symptom; other symptoms include focal neurological signs, seizures, papilledema, and altered sensorium. Diagnosis is typically made with visualization of obstructed flow in the cerebral venous system using one of three imaging modalities: computed tomography-venography (CTV), magnetic resonance imaging with venography (MRV), and diagnostic cerebral angiography. First-line therapy for CVST is anticoagulation, and the prognosis is generally favorable with early detection and prompt treatment. In this case report, we discuss a singular case of a patient presenting with loss of consciousness who was found to have CVST and treated with anticoagulation therapy in the setting of an intraparenchymal hemorrhage.

Abstract
INTRODUCTION Spontaneous central nervous system (CNS) infections in children are rare. Treatment involves surgical intervention and antibiotic therapy. We describe a single centre experience of managing this condition in South Wales. METHODS We performed a retrospective review of surgically managed cases in our unit for patients under 18 years of age between 2008 and 2018. Data were collected regarding aetiology, location, microbiology examination, treatment and outcomes. RESULTS Twenty-six patients were identified of which 25 case notes were available. Fifteen were male and 10 were female. Median age was 12 years (age range 0.3-17 years). Seven patients (28%) had a burr-hole aspiration and 18 (72%) underwent craniotomy. A second procedure was performed in 10 (40%) and a third procedure in two (8%). Fourteen (56%) had a brain abscess, 10 (40%) had subdural empyema (one was bilateral) and one (4%) had an extradural empyema. Fifteen (60%) had a raised WCC (>11.5 × 109/L) and 22 (88%) had a CRP of >10 mg/L at presentation. Three (12%) patients had a normal WCC and CRP at presentation. Overall, 12 (48%) were secondary to sinus infection, with the most common organism being Streptococcus. Seven (28%) were due to otitis media or mastoiditis, six (24%) had no cause identified. The mean number of CT/MRI scans was 6.7 (range 3-13). The mean follow-up period was 16.7 months (range 1-117 months). At last follow up, 19 (76%) had a GOS of 5, five (20%) had a GOS of 4 and one (12%) had GOS of 3. There were no deaths. CONCLUSIONS In Wales, outcomes have improved over time in keeping with other paediatric neurosurgical units in England. Increased availability of imaging resources in our hospital and use of neuro-navigation for all cases in our unit as well as earlier identification of sepsis, communication with microbiologists with dedicated ward rounds and, enhanced identification of causative organisms and contemporary anti-microbials have also contributed towards the improved management of this condition.

Abstract
CONTEXT Cerebral sinovenous thrombosis (CSVT) is a rare but life-threatening condition in the pediatric population and there is no pediatric guidelines regarding anticoagulation for post traumatic CSVT. OBJECTIVE This study aims to describe a cohort of children with post traumatic CSVT and the use of anticoagulant therapy in this population. METHODS A multicenter retrospective study. Patients admitted with post traumatic CSVT in the six participating Pediatric Intensive Care Unit were included. RESULTS Overall, 29 patients (median age 8.2 years [IQR 4.8-14.6], n = 22 (76%) males) were included in the study (Table 1). CSVT was observed within the first 24 h after admission for a half of the patients (n = 14, 50%). Anticoagulation was initiated in 18 patients (62%). No patient received thrombolytic therapy or endovascular treatment. The presence of epidural hematoma was associated with the absence of anticoagulation (n = 0 versus n = 10, p = 0.003). One patient (3%) died of extracranial injury (not related with adverse event of anticoagulation) and in survivors, median Pediatric Overall Performance Category Outcome (POPC) score at discharge from PICU was 2 [IQR 2-4] (i.e., mild disability). Regarding the outcomes of patients, we found no association according to the anticoagulation status (p = 1). Overall, 23 patients (79%) had a follow-up cerebral imaging with a median delay of 42 days [IQR 6-63] after admission. CSVT was still seen in 9 patients (31%). We found no difference regarding the persistence of CSVT between patients according to the anticoagulation status (p = 0.36). The median duration of anticoagulant treatment was 58 days [IQR 44-91] and one patient (3%) experienced adverse event related to anticoagulation. CONCLUSION There were minimal adverse events in patients with post traumatic CSVT treated with therapeutic anticoagulation. However, the effect of anticoagulation on outcomes needs to be confirmed in further studies.

Abstract
BACKGROUND Investigations on the risk factors for the prognosis of cerebral venous sinus thrombosis (CVST) are limited. This study aimed to explore whether specific inflammatory factors and coagulation indictors are associated with functional outcome in patients treated for CVST. METHODS This retrospective study included 137 patients admitted to our hospital between January 2010 and October 2021. The functional outcome was assessed with the modified Rankin Scale (mRS) score at discharge. Patients were divided into two groups, 102 patients with favorable outcomes (mRS 0-1) and 35 patients with poor outcomes (mRS 2-6). The clinical indexes were compared between two groups. Multivariable logistic regression was performed to identify the independent influencing factors for poor outcomes of CVST patients. The prognostic indicators were analyzed using the receiver operating characteristic (ROC) curve. RESULTS Compared with the favorable outcome group, the incidence of impaired consciousness and brain lesion, the levels of D-dimer, RDW, neutrophil count, neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width to platelet ratio (%) on admission were significantly higher in the poor outcome group, while the level of lymphocyte count was significantly lower. After multivariable logistic regression analysis, baseline D-dimer level (odds ratio (OR), 1.180; 95% confidence interval (CI), 1.019-1.366, P = 0.027) and NLR (OR, 1.903; 95%CI, 1.232-2.938, P = 0.004) were significantly associated with unfavorable outcome at discharge. The ROC curve analysis showed that the areas under the curve of D-dimer, NLR and their combined detection for predicting worse outcome were 0.719, 0.707 and 0.786, respectively. CONCLUSIONS Elevated D-dimer level and NLR on admission were associated with an increased risk of poor functional outcome in patients with CVST.

Abstract
Background Cerebral venous sinus thrombosis (CVST) is a form of the cerebrovascular disease characterized by varying degrees of obstruction of veins and cerebral sinuses caused by thrombus. Diagnosis is incredibly challenging due to the wide variety of symptoms and the distinct radiological aspects of affected vessels. In patients with venous thrombosis, the presence of D-Dimer is used as an indicator of the presence of endogenous fibrinolysis. D-Dimer is a by-product of fibrin polymer fragmentation. Objective To investigate the relationship between the level of D-Dimer and the number of sinuses in CVST by Digital Subtraction Angiography (DSA). Methods Retrospective data from September 2021 to September 2022 were used in this analytical observational with a cross-sectional study design. Chi-Square is used for data processing relationship analysis. Results Out of the 54 subjects with elevated levels of D-Dimer, 38 (70.4%) are females, whereas 16 (29.6%) are males. High levels of D-Dimer have been related to a greater risk of sinus thrombosis (p < 0.001). D-Dimer levels were similarly shown to rise in conjunction with the number of sinuses most severely damaged by thrombosis. The most common site for thrombosis to develop in this study were the left sigmoid and left transverse sinuses. Most risk factors were hormonal. Conclusion There is a statistically significant relationship between an increase in the D-Dimer level and the greater number of sinuses involved as determined by DSA in individuals diagnosed with CVST.

Abstract
Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a highly prothrombotic disorder caused by anti-PF4 antibodies that activate platelets and neutrophils, leading to thrombosis. Heparin-induced thrombocytopenia (HIT) is a related anti-PF4 mediated disorder, with similar pathophysiology and clinical manifestations but different triggers (i.e., heparin vs adenoviral vector vaccine). Clinically, both HIT and VITT typically present with thrombocytopenia and thrombosis, although the risk of thrombosis is significantly higher in VITT, and the thromboses occur in unusual anatomical sites (e.g., cerebral venous sinus thrombosis and hepatic vein thrombosis). The diagnostic accuracy of available laboratory testing differs between HIT and VITT; for VITT, ELISAs have better specificity compared to HIT and platelet activation assays require the addition of PF4. Treatment of VITT and HIT is anticoagulation non-heparin anticoagulants; however, heparin may be considered for VITT if no other option is available.

Abstract
Cerebrovascular disease refers to damage to brain tissue caused by impaired intracranial blood circulation. It usually presents clinically as an acute nonfatal event and is characterized by high morbidity, disability, and mortality. Transcranial Doppler (TCD) ultrasonography is a non-invasive method for the diagnosis of cerebrovascular disease that uses the Doppler effect to detect the hemodynamic and physiological parameters of the major intracranial basilar arteries. It can provide important hemodynamic information that cannot be measured by other diagnostic imaging techniques for cerebrovascular disease. And the result parameters of TCD ultrasonography such as blood flow velocity and beat index can reflect the type of cerebrovascular disease and serve as a basis to assist physicians in the treatment of cerebrovascular diseases. Artificial intelligence (AI) is a branch of computer science which is used in a wide range of applications in agriculture, communications, medicine, finance, and other fields. In recent years, there are much research devoted to the application of AI to TCD. The review and summary of related technologies is an important work to promote the development of this field, which can provide an intuitive technical summary for future researchers. In this paper, we first review the development, principles, and applications of TCD ultrasonography and other related knowledge, and briefly introduce the development of AI in the field of medicine and emergency medicine. Finally, we summarize in detail the applications and advantages of AI technology in TCD ultrasonography including the establishment of an examination system combining brain computer interface (BCI) and TCD ultrasonography, the classification and noise cancellation of TCD ultrasonography signals using AI algorithms, and the use of intelligent robots to assist physicians in TCD ultrasonography and discuss the prospects for the development of AI in TCD ultrasonography.

[PMID: 36676061 PMCID: PMC9865306 DOI: 10.3390/life13010111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 12/07/2022] [Accepted: 12/23/2022] [Indexed: 01/03/2023] Open
Abstract
Background: Seizures are a common complication of cerebral venous thrombosis. In this study, we intended to define clinical and neuroradiological factors associated with early and late seizures and predictors for seizure recurrence. Methods: The database of our high-volume tertiary stroke center was screened for patients diagnosed with cerebral venous thrombosis between April 2006 and July 2021. Demographics, clinical, imaging, and instrumental data were collected. Results: Out of a total of 80 patients, 30 had seizures, either within the first week after onset (22 patients) or after (8 patients). Speech impairment and intracerebral bleeding were statistically associated with seizures in univariate analysis, but in a logistic regression model, only brain damage with hemorrhagic infarct and/or presence of brain hematoma [OR 6.051; 95% CI 1.881−19.468] (p = 0.003) were predicting factors for seizures. Late seizures were significantly more frequent in younger age [OR 0.864; 95% CI 0.763−0.978] (p = 0.020). Early seizures resulted as protective factors for recurrence; an altered state of consciousness at baseline and late seizures resulted as predictive factors for relapses (0.0% vs. 81.0%, p = 0.005, and 100.0% vs. 19.0%, p < 0.005, respectively). Conclusions: Our study confirms brain bleeding as the strongest risk factor for seizures after cerebral venous thrombosis. Recurrence is unusual after early seizures, while the presence of late seizures seems to raise the risk of recurrence.

Cerebral Sinovenous Thrombosis in Infants and Children: A Practical Approach to Management. Semin Pediatr Neurol 2022; 44:100993. [PMID: 36456034 DOI: 10.1016/j.spen.2022.100993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 08/27/2022] [Accepted: 08/29/2022] [Indexed: 11/23/2022]
Abstract
Cerebral sinovenous thrombosis (CSVT) is a rare, yet potentially devastating disorder, associated with acute complications and long-term neurologic sequelae. Consensus-based international pediatric CSVT treatment guidelines emphasize early clinical-radiologic recognition and prompt consideration for anticoagulation therapy. However, lack of clinical trials has precluded evidence-based patient selection, anticoagulant choice, optimal monitoring parameters and treatment duration. Consequently, uncertainties and controversies persist regarding anticoagulation practices in pediatric CSVT. This review focuses on commonly encountered issues that continue to pose questions and raise debates regarding anticoagulation therapy among pediatric neurologists and hematologists.

Abstract
Background Neutrophil extracellular traps (NETs) contribute to the creation of a coagulation state in various diseases. Currently, it is not clear whether NETs are present in the thrombi and plasma of patients with cerebral venous sinus thrombosis (CVST). This study aimed to investigate the presence of NETs in thrombi and blood samples from CVST patients and the procoagulant activity (PCA) of NETs during the progression of CVST. Results Thrombi obtained from CVST patients undergoing thrombectomy were examined by immunochemistry using neutrophil elastase (NE), CD66b and citrullinated histone H3(citH3). The presence of NET markers in samples from 37 CVST patients and 32 healthy people was evaluated by ELISA. NET-producing neutrophils and neutrophil-platelet (PLT) aggregates were examined in samples obtained from CVST patients and healthy people by flow cytometry. The TAT complex in plasma sample from each group was detected by ELISA to evaluate the procoagulant activity of NETs in CVST patients. Neutrophils from healthy subjects were treated with PLT-rich plasma in the presence of anti-PF4 antibodies or an autophagy inhibitor and analyzed by flow cytometry and confocal microscopy. After treatment with NETs, the expression of von Willebrand factor (VWF), tissue factor (TF) and CD31 in human brain microvascular endothelial cells (HBMECs) was measured by confocal microscopy and western blotting. Our results showed that NETs were abundant in the plasma and thrombi from CVST patients. Platelet factor 4 (PF4) from CVST PLTs induced NET generation through autophagy. NETs could induce PCA by modulating TF and phosphatidylserine (PS) in CVST. NETs also disrupted the endothelial barrier and transformed ECs into a procoagulant phenotype to exacerbate thrombogenicity. Conclusions NET generation was mediated by PF4 from PLTs through autophagy and contribute to thrombosis in CVST patients.

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 We report a case of a pregnant woman who presented posterior reversible encephalopathy syndrome (PRES) without pre-eclampsia, eclampsia, or any other common causes of PRES. METHODS A 32-year-old primigravida at 25 weeks and 4 days of gestation was admitted to neurology department because of suffering intermittent headache, hearing loss, memory loss with mental and behavioral disorder, and blurred vision for 1 month. She was healthy before without hypertension, migraine, or other medical or family history. Brain magnetic resonance imaging (MRI) revealed diffuse symmetrical high-signal intensity lesions in the white matter, medulla oblongata, without enhancement. After completely multidisciplinary discussion and with the family of the patient, she accepted termination of pregnancy. RESULTS After the operation, the patient improved symptomatically. The follow-up MRI showed a decrease of the white matter lesion after 3 months and complete recovery at postoperative 6 months. The patient returned to work without any neurological sequelae. CONCLUSION It might widen the cause spectrum of PRES that pregnancy itself without pre-eclampsia, eclampsia, or any other known risk factors could cause PRES. Pregnancy with acute or subacute leukoencephalopathy should be screened related causes and risk factors carefully. Hormonal fluctuations during the pregnancy might account for pregnancy-related PRES.

Abstract
BackgroundCerebral venous sinus thrombosis (CVST) is a rare but serious and treatable cause of neurologic symptoms. Due to the variable clinical presentation, CVST was often misdiagnosed. According to published case reports, common clinical manifestations of CVST include headache, focal neurological deficit, epilepsy, papilledema, etc. It is rare, nevertheless, to mention cases of rapidly progressive dementia (RPD).Case presentationWe reported a case of a 62-year-old retired male accountant, a Han Chinese from eastern China, who initially presented with slow response and memory decline. Until 2 months later, his memory declined and slow response deteriorated significantly, and he could not even complete simple tasks like brushing his teeth, washing his face, washing his feet, and dressing himself, and sometimes developed fecal incontinence. His neuropsychological test demonstrated severe cognitive decline. The cerebrospinal fluid (CSF) studies revealed markedly high opening pressure (260 mm of water), and coagulation tests indicated a mild elevation of D-Dimer of 1.19 mg/L. The magnetic resonance venography (MRV) showed thrombosis of the left transverse sinus, sigmoid sinus, and jugular venous bulb and was diagnosed as CVST. He switched from subcutaneous low molecular weight heparin (LMWH) and transitioned to oral anticoagulants at the time of discharge. The repeated CSF studies revealed normal opening pressure. After 5 days of anticoagulant treatment, his symptoms considerably improved, and a 1-month follow-up revealed that he had fully healed with no signs of recurrence.ConclusionThis case demonstrated the clinical heterogeneity of CVST, which should be taken into account for differential diagnosis of RPD. This case study also offered fresh data for the categorization of the clinical traits and the diagnosis of CVST.

Abstract
OBJECTIVE To identify the most frequent causes of secondary pseudotumor cerebri syndrome and compare phenotype, clinical presentation, and symptoms of secondary pseudotumor cerebri syndrome to the primary form of pseudotumor cerebri syndrome, idiopathic intracranial hypertension. METHODS The study was a prospective cohort study including patients with new-onset pseudotumor cerebri syndrome. Diagnostic work up was standardized. Patients were diagnosed with secondary pseudotumor cerebri syndrome or idiopathic intracranial hypertension according to the revised Friedman criteria. Secondary pseudotumor cerebri syndrome patients were categorized into five causes: medication, systemic causes, sleep apnea, cerebrovascular causes, and several competing causes. Phenotype, clinical presentation, symptoms and neuroimaging were compared between groups. RESULTS Out of 278 cases, 28 secondary pseudotumor cerebri syndrome and 120 idiopathic intracranial hypertension patients were included. The most frequent causes of secondary pseudotumor cerebri syndrome were medication (n = 8, 28.6%) and systemic causes (n = 8, 28.6%), followed by sleep apnea (n = 5, 17.9%), cerebrovascular causes (n = 4, 14.3%) and several competing causes (n = 3, 10.7%). Secondary pseudotumor cerebri syndrome and idiopathic intracranial hypertension patients were phenotypically alike and predominately female, premenopausal, and obese. Symptoms and objective findings at disease onset were similar between groups. CONCLUSION Secondary pseudotumor cerebri syndrome should be considered in all patients with suspected pseudotumor cerebri syndrome as secondary pseudotumor cerebri syndrome and idiopathic intracranial hypertension patients are phenotypically and clinically alike. A thorough diagnostic workup is needed as treatment of idiopathic intracranial hypertension and secondary pseudotumor cerebri syndrome is markedly different.

Abstract
Cerebral sinovenous thrombosis (CSVT) is a serious complication during asparaginase therapy in patients with acute lymphoblastic leukaemia (ALL). We identified 46 patients with CSVT among 2651 patients (1‒45 years) treated according to the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol between 2008 and 2018. CSVT cases were prospectively registered in the NOPHO database with retrospective updates. We examined the frequency of asparaginase re‐exposure after CSVT, potential factors associated with asparaginase truncation, and sequelae after CSVT. This work was supported by the Danish Cancer Society and the Danish Childhood Cancer Foundation. The 2.5‐year cumulative incidence of CSVT was 1.9% (95% confidence interval 1.4%–2.5%). The majority of patients (74%, n = 31) were re‐exposed to asparaginase (with low‐molecular‐weight heparin coverage), one of whom had a second CSVT, without neurological sequelae. Patients re‐exposed to asparaginase were earlier in ALL treatment and lacked more asparaginase doses than non‐re‐exposed patients at CSVT diagnosis (median 50 vs. 81 days, p = 0.03; mean 11.2 vs. 8.4 asparaginase doses, p = 0.04). No other examined factors had an impact on asparaginase re‐exposure. At the last follow‐up (median 4.5 years after CSVT), 61% of patients had normal neurological status, and 57% had complete recanalisation of CSVT, with no significant difference between patients re‐exposed and non‐re‐exposed to asparaginase. Our results indicate that re‐exposure to asparaginase is safe after CSVT during anticoagulation.

Abstract
OBJECTIVE The objective for this systematic review is to characterize clinical presentations of Bezold's abscesses to improve awareness and promote earlier diagnoses and prompt intervention in this increasingly rare otologic infection. DATA SOURCES Pubmed/Medline, CINAHL (EBSCOhost), and Web of Science articles in all languages were searched. STUDY SELECTION Inclusion criteria were that the article was either a case report, case series, or retrospective review with individual case data available. Non-English articles were excluded if they lacked an English language abstract and if that abstract lacked information on baseline demographics, clinical presentation, and management. DATA EXTRACTION Included studies were evaluated using fulltext review and demographics, etiology, microbiology, antibiotic usage, and surgical variables were collected. DATA SYNTHESIS Data were qualitatively synthesized, with means and averages obtained for all continuous variables. CONCLUSIONS Bezold's abscess remains a rare otologic infection, but they are relatively commonly associated with serious neurologic and systemic complications. Delay in diagnosis was a frequent commonality and diagnostic vigilance is tantamount in avoiding this sequelae. Aggressive surgical extirpation and long-term antibiotic treatment is recommended.

Abstract
Acute lymphocytic leukemia (ALL) is a common pediatric cancer diagnosis with excellent survival outcomes but significant morbidity, particularly during the induction phase of chemotherapy. Central venous sinus thrombosis (CVST) is a known potential complication of induction therapy; however, it occurs rarely and may be difficult to diagnose, particularly in young children who have limited verbal skills. Herein, we report a case of CVST in a child with B-cell ALL undergoing induction chemotherapy whose main symptoms were headache and a change in the appearance of his artwork noticed by his parents. This astute observation by the child's parents played a critical role in his diagnosis, allowing prompt treatment and eventual recovery.

Abstract
BACKGROUND Cerebral venous thrombosis (CVT) is a rare manifestation of stroke and venous thromboembolism (VTE), compared with deep vein thrombosis (DVT) and pulmonary embolism (PE). We examined whether CVT was associated with adverse cardiovascular events. METHODS A Danish cohort study with adult patients diagnosed with CVT (N = 1,015) between 1997 and 2017. We matched 10 patients with VTE (DVT and PE) to each patient with CVT for age, sex, and diagnosis year. We also matched 10 individuals from the general population to each patient with CVT. We computed cumulative incidence and estimated hazard ratios (HRs) with 95% confidence intervals (95% CIs) at 5 years for major bleeding, intracranial bleeding, ischemic stroke, and cardiovascular events. Death was examined separately. RESULTS Major bleeding risks were 1.2% for CVT and 0.7% for VTE at 6 months; these risks increased to 2.7% and 2.6%, respectively, at 5 years. Although rare, intracranial bleeding risks were markedly higher for CVT (2.9%) than for VTE (0.4%) at 5 years (HR = 8.9, 95% CI: 5.3-15.1). Incidences of ischemic stroke were 5.9% for CVT and 0.3% for VTE, at 6 months; and 10.0% and 1.4%, respectively, at 5 years (HR = 9.5, 95% CI: 7.1-12.7). In contrast, incidence of cardiac events was lower for CVT that VTE (1.7% vs. 3.6% at 5 years). Mortality risk was higher after CVT compared with VTE, at 6 months (6.6% vs. 3.8%), but the risks differed little at 5 years (14.3% vs. 14.1%). CONCLUSION Intracranial bleeding, ischemic stroke, and mortality risks were higher for patients with CVT than matched patients with VTE and the general population, particularly within 6 months after diagnosis.

Abstract
This was a rare case of preseptal cellulitis with an unexpected complication by cerebral venous sinus thrombosis. A 73-year-old woman with poorly controlled diabetes mellitus presented with a week history of swelling and redness on the left upper eyelid and right forehead, associated with poor oral intake, lethargy, and fever. She was generally lethargic with poor verbal response. She had cellulitis of the left upper eyelid and right forehead with the left upper eyelid necrosis. Computed tomography venography of the brain revealed thrombosis of the right transverse sinus, right sigmoid sinus, and right internal jugular vein. She later developed left upper eyelid and right forehead abscesses. Incision, drainage, and wound debridement were performed. She was treated with intravenous antibiotics and anticoagulant. After 1 week of treatment, the preseptal and forehead cellulitis had resolved. However, she passed away due to aspiration pneumonia with respiratory failure on day-13 of hospitalization.

Abstract
Background Cerebral venous sinus thrombosis (CVST) is a rare neurovascular disorder with highly variable manifestations and clinical courses. Animal models properly matched to the clinical form of CVST are necessary for elucidating the pathophysiology of the disease. In this study, we aimed to establish a rat model that accurately recapitulates the clinical features of CVST in human patients. Methods This study consisted of a clinical analysis and animal experiments. Clinical data for two centres obtained between January 2016 and May 2021 were collected and analysed retrospectively. In addition, a Sprague–Dawley rat model of CVST was established by inserting a water-swellable rubber device into the superior sagittal sinus, following which imaging, histological, haematological, and behavioural tests were used to investigate pathophysiological changes. Principal component analysis and hierarchical clustering heatmaps were used to evaluate the similarity between the animal models and human patients. Results The imaging results revealed the possibility of vasogenic oedema in animal models. Haematological analysis indicated an inflammatory and hypercoagulable state. These findings were mostly matched with the retrospective clinical data. Pathological and serological tests further revealed brain parenchymal damage related to CVST in animal models. Conclusions We successfully established a stable and reproducible rat model of CVST. The high similarity between clinical patients and animal models was verified via cluster analysis. This model may be useful for the study of CVST pathophysiology and potential therapies.

Abstract
Vitamin K antagonists (VKAs) are the standard oral anti-coagulant treatment for patients with cerebral venous thrombosis (CVT). However, the direct oral anti-coagulants (DOACs) started replacing VKAs also in this setting. We aimed to evaluate safety and efficacy of the DOACs for CVT treatment. We performed a systematic review and meta-analysis (PROSPERO protocol registration number CRD42020191472). The electronic databases MEDLINE, EMBASE and CENTRAL were searched from inception to January 2022. We included randomised controlled trials (RCTs) and observational studies, enrolling at least 10 adult patients with CVT treated with any DOACs. Twenty-three studies were included, for a total of 618 CVT patients treated with DOACs (treatment duration range 3-12 months). Mortality rate was 1.76% [95% confidence interval (CI) 0.70%-3.24%; I2 = 0%; 5/428 patients, 18 studies]; major bleeding 2.41% (95% CI 1.26%-3.91%; I2 = 1.5%; 12/534 patients, 21 studies); recurrent thrombosis 2.05% (95% CI 1.04%-3.37%; I2 = 0%; 10/577 patients, 21 studies); excellent neurological outcome 85.9% (95% CI 79.0%-91.7%; I2 = 63.7%; 289/340 patients, 13 studies); vessel recanalisation 89.0% (95% CI 82.9%-93.9%; I2 = 62.7%; 316/359 patients, 16 studies). No significant differences emerged by study design (RCTs vs. observational studies) or by treatment (DOACs vs. VKAs). This systematic review showed that the DOACs might represent a reasonable oral anti-coagulant treatment option for CVT patients.
