Microgravity Effects on Glioma Cells: A Comprehensive Review.

High-grade gliomas (HGGs) represent a formidable challenge in neuro-oncology due to their aggressive nature and resistance to current therapeutic interventions, which include surgery, radiation, chemotherapy, and emerging immunotherapies. Despite these efforts, the prognosis for patients remains poor, emphasizing the urgent need for novel treatment strategies. One promising avenue of exploration is microgravity, a condition experienced during spaceflight and simulated in laboratories on Earth, which induces significant physiological changes in cells and tissues.

Pre-treatment DTI markers: predicting clinical outcomes in microvascular decompression for classic trigeminal neuralgia - a systematic review.

Background And Purpose: Trigeminal neuralgia (TN) is a severe chronic pain condition, typically affecting patients over 50-year-old, caused by the compression of the nerve at the root entry zone (REZ) by blood vessels. While the diagnosis is clinical, advanced imaging like diffusion tensor imaging (DTI) is crucial to identify underlying causes and assessing nerve damage. DTI may help develop neuroimaging markers to improve understanding of TN and predict surgical outcomes.

Not Every Size Fits All: Surgical Corridors for Clival and Cervical Chordomas-A Systematic Review of the Literature and Illustrative Cases.

Clival chordomas represent a rare but clinically significant subset of skull base tumors, characterized by a locally aggressive nature and a location in proximity to vital neurovascular structures. Surgical resection, often combined with adjuvant therapies, remains the cornerstone of clival chordoma treatment, and various approaches and techniques have evolved to maximize tumor removal while preserving neurological function. Recent advancements in skull base surgery, imaging, and adjuvant therapies have improved outcomes by reducing morbidity and thus enhancing long-term survival.

Gangliogliomas (GG), while typically indolent, can manifest as anaplastic variants (AGG), necessitating comprehensive treatment strategies. This case study explores a unique surgical approach for a patient with bilateral, intra-extraventricular lesions infiltrating the corpus callosum, highlighting the complexities of managing such cases.

Caregivers' Perspective and Burden of the End-of-Life Phase of Patients with Glioblastoma: A Multicenter Retrospective Study.

Background: Glioblastoma is the most common aggressive primary brain tumor in adults. Changes in cognition, personality, and behavior of patients as well as side effects of treatments cause unique challenges for providing care and may impact caregiver burden in different ways.

Methods: This retrospective study included 45 patients with a diagnosis of glioblastoma treated between January 2022 and June 2023 in 2 neurosurgical departments.

The role of MRgFUS in the treatment of neuropsychiatric disorders: a state of the art.

Introduction: Magnetic resonance-guided focused ultrasound (MRgFUS) is a contemporary non-invasive ablative procedure that utilizes high- or low-intensity ultrasound, guided and monitored by magnetic resonance imaging (MRI). While MRgFUS has been established as an effective treatment for conditions like essential tremor and tremor-dominant Parkinson's disease, it has recently emerged as a safe and promising ablative minimally invasive procedure for the management of treatment-resistant psychiatric disorders. Indeed, despite the availability of various pharmacological and behavioral therapies, a subset of psychiatric patients remains refractory to conventional treatments.

From data to practice: brain meningioma treatment in elderly patients - a survey of the Italian Society of Neurosurgery (SINch®) and systematic review and meta-analysis.

The management of meningioma in elderly patients (MEP) presents a complex and evolving challenge. Data available offer conflicting information on treatment options and complications. This survey aimed to examine the current approach to MEP, comparing the national profile to data in the current literature.

Purpose: This systematic review aims to investigate the role of nuclear imaging techniques in detecting incidentalomas and their impact on patient management.

Methods: Following PRISMA guidelines, a comprehensive literature search was conducted from February to May 2022. Studies in English involving patients undergoing nuclear medicine studies with incidental tumor findings were included.

Hypothalamic Hemangioma-like Pilocytic Astrocytoma in an Adult Patient: A Systematic Review with a Focus on Differential Diagnosis and Neurological Presentation.

Pilocytic astrocytoma (PCA) are commonly observed as slow-growing noncancerous brain tumors in pediatric populations, but they can also occur in adults, albeit rarely. When located in diencephalic regions, particularly in the hypothalamus, they present unique diagnostic and management challenges due to their rarity and overlapping clinical and radiological features with other intracranial pathologies. This systematic review aims to provide a comprehensive understanding of hypothalamic PCA in adults, focusing on their differential diagnosis, neurological presentation, diagnostic modalities, treatment strategies.

Neurologic and Neuropsychological Outcomes for Treatment of Unruptured Middle Cerebral Artery Aneurysms: Standard Pterional Versus Minipterional Approach in a Retrospective Single-Center Analysis.

Background: In accordance with technique advancement and minimal invasiveness surgical approaches, the minipterional has progressively replaced the standard pterional approach for treatment of unruptured middle cerebral artery (MCA) aneurysms. Nowadays, multimodal intraoperative resources including microDoppler and microflow probes, indocyanine green videoangiography, and neurophysiologic monitoring constitute a fundamental prerequisite for increasing the safety of the clipping procedure. Our study investigated and compared in a single-center experience the effect of the evolution of a minimally invasive and multimodal approach in unruptured MCA aneurysm surgery by measuring postoperative complication rate, recovery time, and long-term neuropsychological and functional outcomes.

A Difficult Case of Ventriculitis in a 40-Year-Old Woman with Acute Myeloid Leukemia.

Ventriculitis and nosocomial meningitis caused by carbapenem-resistant Gram-negative and vancomycin-resistant Gram-positive bacteria represent a growing treatment challenge. A case of ventriculitis and bacteremia caused by carbapenem-resistant, KPC-producing and vancomycin-resistant in a young woman with acute leukemia who was successfully treated with meropenem/vaborbactam (MVB), rifampicin, and linezolid is described in this paper. This case report emphasizes the importance of a multidisciplinary strategy, including infectious focus control, for the treatment of device-associated central nervous system (CNS) infections from multidrug-resistant bacteria.

Multiple Abdominal abscesses following ventriculoperitoneal shunt placement in an immunosuppressed patient: An illustrative case.

Background: Ventriculoperitoneal (VP) shunt placement is one of the most performed procedures in neurosurgery to treat various types of hydrocephalus (HC). Immediate or late postoperative complications may quite commonly occur, especially in immunosuppressed patients, who are predisposed to develop rare and difficult-to-treat conditions.

Case Description: Herein, we report the case of a 41-year-old female patient with a prior history of acute myeloid leukemia, followed by a tetra-ventricular acute HC due to a spontaneous non-aneurysmal subarachnoid hemorrhage.

Coexistence of mastoid, frontal and vertebral hemangiomas in a patient with diabetic neuropathy: Possible correlation between diabetic angiopathy and intraosseous neoangiogenesis.

Bony hemangiomas are benign vascular lesions with an expansive growth; usually they tend to obliterate the entire bony cavity. They are typical lesion of the spinal bones, but they can rarely arise within other bones of the neurocranium. Diabetic microangiopathy is a condition characterized by the development of aberrant vessel tangles anastomosed to each other due to dysregulated neoangiogenesis.

Preoperative Angiographic Protocol for the Surgical Management of Spinal Dural Arteriovenous Fistulas: A Technical Nuance for Safe Minimally Invasive Surgery.

Background: Interruption of the fistulous point is the goal of treatment of spinal dural arteriovenous fistulas (dAVFs). Microsurgery remains a highly efficient treatment in terms of complete occlusion with the lowest risk of recurrence rate. It is reported that the hardest step involves finding the fistulous site itself, potentially extending surgical access and time and increasing potential postoperative surgical-related complications.
