Nonacute Subdural Hematoma Evacuation Using a Rigid Endoscopy System: A Clinical Study.

Aim: To determine the clinical relevance of a rigid endoscopy surgical method for subdural hematomas, as previously described in a cadaver study.

Material And Methods: Between May 2021 and September 2023, 21 patients underwent subdural hematoma drainage using a 0-degree rigid endoscope. Traumatic acute subdural hematomas were excluded.

A Novel Perspective to Gamma-Knife Radiosurgery for Solitary Meningiomas: Adaptability of Fast Imaging Employing Steady-State Acquisition/Constructive Interference in Steady-State Magnetic Resonance Imaging.

Aim: To compare T1-weighted contrast-enhanced (T1+C) with fast imaging employing steady-state acquisition (FIESTA) magnetic resonance imaging (MRI) sequences to protect healthy brain tissue during meningioma treatment with Gamma-Knife radiosurgery (GKRS).

Material And Methods: After reviewing the data of 54 patients with solitary meningioma who underwent GKRS between January 2020 and June 2022, demographic characteristics were noted, tumor volumes on T1+C and FIESTA MRI sequences were measured, and sequences were compared. The patients were then divided into two groups according to the presence of invasion to intracranial venous sinuses (groups 1 and 2, respectively).

Applications of enhanced recovery after surgery protocols for unruptured anterior circulation aneurysms in tertiary-level healthcare institutions: a national study.

Objective: Enhanced recovery after surgery (ERAS) protocols are standardized perioperative care that reduce patients' stress response during hospitalization and improve hospitalization time, complication rates, costs, and readmission rates. This study aimed to investigate the application rate of protocols for elective craniotomy in the surgery of unruptured anterior circulation aneurysms (AnCAs) at tertiary-level healthcare (TLH) institutions in Türkiye and its effect on the outcomes of the patients.

Methods: An electronic survey was sent to all Turkish TLH institutions (n = 127) between May and June 2023.

Hydatid Cyst of the Cerebellopontine Angle.

Hydatid disease is caused by Echinococcus granulosus. The liver is the first organ of entry, while the central nervous system is affected in about 2% of cases. Primary brain hydatid cyst is extremely rare.

The effectiveness of gamma knife radiosurgery for the management of residual high-grade gliomas: A single institutional study.

High-grade gliomas (HGGs) are presently managed via surgical resection, external beam radiation therapy (EBRT), and chemotherapy. Although Gamma Knife radiosurgery (GKRS) is currently used to manage HGGs, it has not been considered standard care. This paper aims to compare the contribution of GKRS to clinical outcomes in patients in which gross total resection (GTR) cannot be achieved.

Targeting Cancer Cell Metabolism with Metformin, Dichloroacetate and Memantine in Glioblastoma (GBM).

Aim: To investigate the effects of metformin, dichloroacetate (DCA), and memantine on T98G and U87-MG human glioblastoma (GBM) cells to target tumor cell metabolism in a multi-directional manner.

Material And Methods: IC50 levels for metformin, DCA, metformin+DCA and memantine were determined by MTT assay in T98G and U87-MG cells in vitro. Casp3, Bcl-2, Bax, c-Myc and GSK-3B protein expressions were investigated post treatments.

Subdural Hematoma Evacuation via Rigid Endoscopy System: A Cadaveric Study.

The utilization of endoscope-assisted surgery is becoming a more common modality for the surgical treatment of subdural collections. Considering the inflexible construction of the rigid endoscope, it's not clear where to perform the optimal craniotomy. Twenty four craniotomies (3 cm diameter) were performed in 8 hemicrania.

Academic performance after neurosurgery residency training in Turkey: a national survey.

Objective: Neurosurgery training programs aim to train specialists. In addition, they are expected to equip the residents with necessary knowledge and skills for academic development. This study aims to gain insights into academic productivity after neurosurgeons graduated from residency training in Turkey.

Characterizing the Intraoperative Microelectrode Recording-Induced Microlesion Effect on Motor Symptoms in Patients with Parkinson's Disease Undergoing Deep Brain Stimulation of the Subthalamic Nucleus.

Aim: To investigate microelectrode recording (MER)-induced microlesion effect (MLE) on the motor symptoms of 30 patients with Parkinson’s disease (PD) who underwent deep brain stimulation of the subthalamic nucleus.

Material And Methods: MER-induced MLE was evaluated based on the difference between tremor, rigidity, and bradykinesia scores in the preoperative off-state and intraoperative state following MER and before test stimulation.

Results: MLE scores improved by 21.

Cervical Spinal Ependymoma With Hemorrhage in a Renal Transplant Patient.

Ependymomas are the most common intramedullary spinal tumors in adults and constitute around 20% of all spinal tumors in adults. There are 3 subgroups of ependymomas according to World Health Organization classification: subependymoma or myxopapillary (grade 1), ependymoma (grade 2), and anaplastic (grade 3). Therapy for patients is aimed at safe and total surgical removal and, in selected cases, postoperative radiotherapy.

Vertebral Body Lipoma: An Unusual Pathology Treated With Kyphoplasty.

Study Design: Case report.

Objective: This case report is unique since this is the first vertebral lipom case that was treated by kyphoplasty alone.

Summary Of Background Data: Vertebral lipoma is extremely rare and our search of the English literature has revealed 20 patients in 16 reports.

Intracranial Fungal Infection After Solid-Organ Transplant.

Neurologic complications after solid-organ transplant reveal a great spectrum of pathologies. Intracranial hemorrhages, cerebral ischemic lesions, infarctions, lymphoproliferative disorders, and infections, including aspergillosis, have been observed after liver transplant. Fungi constitute nearly 5% of all central nervous system infections, mainly occurring in immunocompromised patients.

Effects of quercetin on chronic constriction nerve injury in an experimental rat model.

Background: Flavonoids are popular substances in the literature, with proven effects on cardiovascular, neoplastic and neurodegenerative diseases. Antioxidant effect is the most pronounced and studied one. Among thousands of flavonoids, quercetin (QUE) is a prototype with significant antioxidant effects.
