This study aims to evaluate the clinical and radiological features, histopathological characteristics, treatment modalities, and their effectiveness, as well as long-term follow-up results of pediatric spinal ependymomas treated at a single institution. In this retrospective study, medical records of 14 pediatric patients (3 females and 11 males) who were surgically treated for spinal ependymoma in our institution between 1995 and 2020 were reviewed. Data regarding age, gender, presenting symptoms and signs, radiological findings, postoperative status, extent of resection, histopathological grading, recurrence, tumor growth, seeding, and adjuvant treatment were collected and analyzed.

Clinical evaluation, diagnosis, and decision-making for metastatic spine tumors: WFNS spine committee recommendations.

Introduction: Spinal metastases are a significant concern for patients with advanced cancer, leading to pain, neurological deficits, and reduced quality of life. They occur in up to 70% of cancer patients, with the vertebral column being the most common osseous site for metastatic disease. An approximate 10% of patients with vertebral body metastases eventually develop spinal cord compression, which can potentially cause severe and permanent disability.

Exploring habenular structural connectivity in Parkinson's disease: insights from 7 T MRI study.

Background: PD is marked by both motor and non-motor symptoms, with its pathophysiology involving many neural pathways and brain regions beyond the dopaminergic system. While mainly gray matter changes have been noted, white matter changes also exist in PD. Habenula, known for its role in reward processing, mood regulation, motor functions, and cognition, is of interest due to its connection to mood disorders in PD.

Case reports about the efficacy of this block in the literature are limited. In this report, we would like to share our successful QIPB experience with a patient with chronic myofascial low back pain.

A Review on Hepatoprotective Effect of Chrysin: Preclinical Implications and Molecular Cascades Came into Focus.

Chrysin, a flavone nutraceutical, possesses several beneficial pharmacological properties, which has gained much emphasis in recent years. The biological effects of chrysin are exerted due to impeding or activating multifarious cellular and molecular pathways. Our findings indicated that chrysin inhibited tumor progression in various cancer cell lines by repressing the formation of a sphere and upregulated protein expression of Src homology region 2 domain-containing phosphatase-1 (SHP-1), alleviating phosphorylated-signal transducer and activator of transcription 3 (p-STAT3) and transaction workflow innovation standards team1 (Twist1), sustaining phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) and endorsing mitogen-activated protein kinase kinase1 (MEK1) overexpression, increasing the cytochrome c release, mitochondrial reactive oxygen species (ROS) formation, matrix metalloproteinases (MMP) collapse, and caspase-3 activity, modulating p53/ B-cell lymphoma-2 (Bcl-2)/caspase-9 cascade, cyclooxygenase- 2 (COX-2), nuclear factor kappa B proposition 65 (NF-kB p65) expression and also decreasing the expression of nuclear factor erythroid 2-related factor 2 (Nrf2).

Holocord intramedullary pilocytic astrocytoma mimicking holocord spinal abscess: a case report and literature review.

Purpose: This report aims to present a case of a child with holocord pilocytic astrocytoma and review the existing literature to provide insights into current management strategies.

Case Presentation: An 11-month-old patient presented with progressive quadriplegia and was initially diagnosed with a spinal abscess. MRI revealed a heterogeneously enhancing cystic intramedullary lesion extending from the cervicomedullary region to the conus medullaris.

Magnetic resonance imaging findings of cerebral venous malformations.

Purpose: Our study aimed to evaluate the incidence and anatomical locations of cerebral venous malformations (CVMs), their alterations over time, and magnetic resonance imaging (MRI) findings of their relationships with each other in patients who underwent magnetic susceptibility-weighted imaging (SWI) and contrast-enhanced MRI.

Methods: The drainage pattern of developmental venous anomalies (DVAs), the number of collecting veins, DVA thrombosis, signal-intensity abnormalities, and hemosiderin deposits (nodular, diffuse, or both) related to the DVA, were examined. The alterations over time in cavernomas (type and size) were assessed.

Pro's and con's of different blocks for postoperative analgesia after video-assisted thoracic surgery.

Purpose Of Review: Although there are a lot of studies examining the effects of different blocks for postoperative analgesia after video-assisted thoracic surgery (VATS), the results are controversial.

Recent Findings: Paravertebral block, serratus anterior plane block and erector spinae plane block appear to be effective and beneficial for post-VATS analgesia, but probably in different manners.

Summary: All three blocks can be suggested for daily practice, the choice should be based on personal experience and preference of the anesthetist.

A new nano approach to prevent tumor growth in the local treatment of glioblastoma: Temozolomide and rutin-loaded hybrid layered composite nanofiber.

Total resection of glioblastoma (GB) tumors is nearly impossible, and systemic administration of temozolomide (TMZ) is often inadequate. This study presents a hybrid layered composite nanofiber mesh (LHN) designed for localized treatment in GB tumor bed. The LHN, consisting of polyvinyl alcohol and core-shell polylactic acid layers, was loaded with TMZ and rutin.

Outcomes of neuroendoscopy for suprasellar arachnoid cysts: a single center experiences.

Background: Arachnoid cysts are extra parenchymal, intra-arachnoid fluid collections of unknown origin, similar in content to cerebrospinal fluid. Suprasellar arachnoid cysts are a rarer localization resulting from abnormalities of the Liliequist membrane or cystic dilatation of the interpeduncular cisterna. We aimed to contribute to the literature by presenting a series of suprasellar arachnoid cyst cases with endoscopic intervention and long-term results.

Comparison of syndromic and non-syndromic craniosynostosis cases followed in a tertiary pediatric intensive care unit: a case control study.

Introduction: Craniosynostosis, marked by premature skull suture closure, manifests as isolated or syndromic cases. While isolated cases are more common, syndromic craniosynostoses are associated with a range of complications. This study aims to compare postoperative outcomes in isolated and syndromic craniosynostosis, hypothesizing greater complications in the latter.

Large language models surpass human experts in predicting neuroscience results.

Scientific discoveries often hinge on synthesizing decades of research, a task that potentially outstrips human information processing capacities. Large language models (LLMs) offer a solution. LLMs trained on the vast scientific literature could potentially integrate noisy yet interrelated findings to forecast novel results better than human experts.
