Gamma Knife Radiosurgery as a Salvage Treatment for Nasopharyngeal Carcinoma with Skull Base and Intracranial Invasion (T4b).

It is usually difficult to achieve good outcomes with salvage treatment for recurrent nasopharyngeal carcinoma (NPC) because of its deep-seated location, surrounding critical structures, and patient history of high-dose irradiation. Gamma Knife radiosurgery (GKS) is a treatment option for malignancies with skull base and intracranial invasion. We conducted a retrospective, observational, single-center study including 15 patients with recurrent NPC (stage T4b) involving the skull base and intracranial invasion, who underwent GKS as a salvage treatment.

Superimposing Pre-Cranioplasty on Pre-Craniectomy Images to Gauge Feasibility of Early Cranioplasty: A Proof of Concept.

Cranioplasty to reconstruct a skull defect after a decompressive craniectomy (DC) is a common neurosurgical procedure. However, cranioplasty is associated with relatively high complication rates, with optimal timing from craniectomy to cranioplasty remaining a controversial matter. Recent studies demonstrated early cranioplasty with appropriate risk mitigation to be a viable option with many clinical advantages, propelling the advocacy for cranioplasty as soon as brain swelling resolves.

The purpose of this retrospective cohort study was to investigate the potential effect of acupuncture to protect stroke patients from dementia.

Adjunctive Statin Therapy Reduces Mortality After Acute Hemorrhagic Stroke.

Background: Statin treatment improves clinical outcomes in patients with ischemic strokes, although there is no evidence regarding the safety of statin therapy in patients with intracerebral hemorrhage (ICH). This study aimed at evaluating the effects of continuing statin treatment after ICH.

Methods: Data were obtained from the National Health Insurance Research Database in Taiwan.

Simvastatin-Ezetimibe enhances growth factor expression and attenuates neuron loss in the hippocampus in a model of intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) is a common and severe neurological disorder associated with high morbidity and mortality rates. Despite extensive research into its pathology, there are no clinically approved neuroprotective treatments for ICH. Increasing evidence has revealed that inflammatory responses mediate the pathophysiological processes of brain injury following ICH.

Haemorrhage rates of ruptured and unruptured brain arteriovenous malformation after radiosurgery: a nationwide population-based cohort study.

Objectives: The present nationwide population-based cohort study aims to assess the effectiveness of gamma knife radiosurgery (GKS) on ruptured and unruptured brain arteriovenous malformations (AVMs) by evaluating the haemorrhage rates.

Design: A nationwide, retrospective cohort study.

Setting: Taiwan National Health Insurance Research Database (NHIRD).

Simvastatin and Simvastatin-Ezetimibe Improve the Neurological Function and Attenuate the Endothelial Inflammatory Response after Spinal Cord Injury in Rat.

During a spinal cord injury (SCI), mechanical trauma rapidly leads to a blood-spinal cord barrier (BSB) disruption, neural cell damage, axonal damage, and demyelination, followed by a cascade of secondary inflammatory reactions. These inflammatory responses spread the damage to the neural cells and impair the recovery of neurological functions. In the present study, we evaluated the efficacy of simvastatin and a simvastatin-ezetimibe combination therapy in managing the endothelial inflammatory response in an SCI rat model.

Fluoroscopically-Guided Superior Hypogastric Plexus Neurolysis Using a Single Needle: A Modified Technique for a Posterolateral Transdiscal Approach.

Analysis of Patients with Myelopathy due to Benign Intradural Spinal Tumors with Concomitant Lumbar Degenerative Diseases Misdiagnosed and Erroneously Treated with Lumbar Surgery.

Objective: When a cervical or thoracic benign intradural spinal tumor (BIST) coexists with lumbar degenerative diseases (LDD), diagnosis can be difficult. Symptoms of BIST-myelopathy can be mistaken as being related to LDD. Worse, an unnecessary lumbar surgery could be performed.

The risk of cataractogenesis after gamma knife radiosurgery: a nationwide population based case-control study.

Background: Medical radiation is considered a factor responsible for cataractogenesis. However, the incidence of this ophthalmologic complication resulting from gamma knife radiosurgery (GKRS) has not yet been reported. The present study aimed to determine the risk of cataractogenesis associated with radiation exposure from GKRS.

Clinical outcome following DIAM implantation for symptomatic lumbar internal disk disruption: a 3-year retrospective analysis.

Background/objective: Internal disk disruption (IDD), an early event of lumbar disk degeneration, is the most common cause of low back pain. Since increased intradiskal pressure (IDP) is associated with symptoms and progression of disk degeneration, unloading a painful disk with an interspinous process device (IPD) is a rational treatment option. The goal of this study was to evaluate the effectiveness of dynamic stabilization with an IPD in the treatment of symptomatic IDD of the lumbar spine.

Reduction in adjacent-segment degeneration after multilevel posterior lumbar interbody fusion with proximal DIAM implantation.

OBJECT Multilevel long-segment lumbar fusion poses a high risk for future development of adjacent-segment degeneration (ASD). Creating a dynamic transition zone with an interspinous process device (IPD) proximal to the fusion has recently been applied as a method to reduce the occurrence of ASD. The authors report their experience with the Device for Intervertebral Assisted Motion (DIAM) implanted proximal to multilevel posterior lumbar interbody fusion (PLIF) in reducing the development of proximal ASD.

The treatment of a complicated penetrating head injury caused by a steel bar is presented here. A 66-year-old woman fell onto a steel bar at a construction site and it penetrated the mandible, entered the sinus and orbital cavities, and reached the base of the frontal bone.

An unusual and complex congenital heart disease in a patient with a ruptured cerebral aneurysm.

A 38-year-old woman had complex, congenital heart anomalies, including double-outlet right ventricle with mitral atresia, severe left ventricle hypoplasia, atrial septal defect, and severe pulmonary stenosis, for which she had not received appropriate treatment. She presented to our institution with an intense sudden-onset headache that had initiated while sleeping. Brain computed tomography indicated the presence of spontaneous subarachnoid hemorrhage.

Simvastatin combined with antioxidant attenuates the cerebral vascular endothelial inflammatory response in a rat traumatic brain injury.

Traumatic brain injury (TBI) leads to important and deleterious neuroinflammation, as evidenced by indicators such as edema, cytokine production, induction of nitric oxide synthase, and leukocyte infiltration. After TBI, cerebral vascular endothelial cells play a crucial role in the pathogenesis of inflammation. In our previous study, we proved that simvastatin could attenuate cerebral vascular endothelial inflammatory response in a rat traumatic brain injury.

Association between autoimmune rheumatic diseases and the risk of dementia.

Aim: Autoimmune rheumatic diseases (ARD) are characterized by systemic inflammation and may affect multiple organs and cause vascular events such as ischemic stroke and acute myocardial infarction. However, the association between ARD and increased risk of dementia is uncertain. This is a retrospective cohort study to investigate and compare the risk of dementia between patients clinically diagnosed with ARD and non-ARD patients during a 5-year follow-up period.
