The objective of this study was to analyze the characters of the cerebellopontine angle (CPA) metastases from central nerve system (CNS) tumors. Ten patients were reviewed for the period between 2008 and 2015. The clinical and neuroimaging features, and treatment outcomes were analyzed retrospectively. The average period during primary diagnosis through the diagnosis of CPA metastases was 42.4months. Among the 10 cases, the primary tumors and metastases were found simultaneously in 3 cases, the metastases after primary tumor removal were found in 5 cases, and the metastases after stereotaxic radiosurgery were found in 2 cases...

Rostral ventrolateral medulla (RVLM) plays an essential role in blood pressure homeostasis. This study was aimed to investigate the mechanism of neuronal activity and synaptic transmission in the RVLM. Medulla oblongata slices were carefully obtained from brainstem of rats. With continues perfusion of artificial cerebrospinal fluid (ACSF), the spontaneous firing of slices and amplitudes were assayed by conventional whole cell patch-clamp recording after addition of gamma-aminobutyric acid (GABA), α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) and N-methyl d-aspartate (NMDA)...

Isaacs syndrome is a form of peripheral nerve hyperexcitability, characterized by spontaneous muscle twitching and stiffness. Some patients are reported to be positive for CASPR2 antibody that may be one of the pathogenic autoantibodies in Isaacs syndrome. We reported a series of three patients with Isaacs syndrome, including their clinical features, electrophysiologic findings, laboratory parameters and therapeutic responses. All the three patients were positive for CASPR2 antibodies examined on transfected human embryonic kidney 293 cells by indirect immunofluorescence method...

Medial prefrontal cortex (mPFC) is usually known for participating in virtually all self related processing. However, few have investigated the role of mPFC in modulating conscious awareness. This study aimed to depict the relationship between the mPFC connectivity and the severity and outcome of the disorders of consciousness (DOC) among patients with acquired brain injury. Thirty-four patients with DOC (17 in a minimally conscious state and 17 in an unresponsive wakefulness syndrome/vegetative state) and 11 healthy controls were recruited, underwent clinical assessment and resting-state functional MRI scan, and were further followed up to evaluate recovery outcome using the Glasgow Outcome Scale...

The insula is now regarded as a potential site of epileptogenesis in drug-resistant epilepsy, and the advent of microsurgical techniques has allowed insular cortectomy to become a treatment of choice when the insular cortex is involved in the seizure focus. However, considering the evidence of an insular role in socio-emotional processing, it remains unknown whether these cortical resections disturb personality and social behavior as experienced in daily life. We examined such changes in a group of patients (n=19) who underwent epilepsy surgery involving partial or complete resection of the insula, and compared them to a group of patients who underwent standard temporal lobe epilepsy (TLE) surgery (n=19) as a lesion-control group...

Trousseau syndrome is defined as a variant of intravascular thromboembolism that is induced by cancer. It may manifest itself as cerebral embolisms in some cases; however, when the cancer is not diagnosed, this identification may be difficult. Therefore, cerebral embolisms are often treated without identifying the cancer, which can worsen a patient's condition. The purpose of this study was to determine the differences in clinical features between cerebral embolisms induced by cancer (Trousseau syndrome) and those that are due to other causes, such as cardiogenic embolisms and artery-to-artery stroke...

Stella Taylor Portella, Marcus André Acioly
According to the original description by Modic et al., the natural course of bone marrow signal abnormalities is an inexorable, progressive one, however recent evidence has demonstrated in healthy individuals and those suffering from lumbar disc herniation that the course of endplate degenerative changes is rather dynamic and sometimes regressive. The evolution of such changes in lumbar fused segments and adjacent levels is largely unknown. The literature relevant to the course of Modic changes on fused and adjacent levels, as well as its clinical correspondence in patients undergoing posterolateral lumbar fusion was collected...

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory arterial disease that most commonly affects the renal and internal carotid arteries, but intracranial FMD is very rare. We report a patient with FMD involving the posterior cerebral arteries (PCAs). A 24year old female was presented with a 4day history of right homonymous hemianopsia with throbbing headache in the left temporo-occipital area. The brain magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the left PCA territory, while the Time of Flight (TOF) magnetic resonance angiogram (MRA) showed segmental luminal irregularities in the left proximal PCA...

Craniectomy is a life-saving procedure. Subsequent cranioplasty with autologous skull bone has a bone resorption rate from 4% to 22.8% and an infection rate from 3.3% to 26%. There are concerns with their viability and the potential microbial contamination as they were explanted for a long period of time. Eighteen cranial bone flaps stored at Prince of Wales Hospital Skull Bone Bank during the period from June 2011 to March 2016 were identified. Ethics approval was obtained. Bone chips and deep bone swabs were collected for osteoblast culture and microbial culture...

A Phase 3 clinical study demonstrated that the addition of 200kHz Tumor Treating Fields (TTF) to temozolomide in the post-radiation (RT) phase of therapy in newly diagnosed glioblastoma increases progression free and overall survival (resulting in FDA and European Union approval). Preclinical studies have demonstrated the ability of TTF to act as a radiosensitizer, suggesting concurrent TTF and RT may have clinical utility. The removal and replacement of TTF transducer arrays from the scalps of patients on a daily basis, i...

Vestibular neuritis is one of the most common peripheral causes of acute vestibular syndrome, of which the diagnosis is generally based on a comprehensive interpretation of clinical and laboratory findings following reasonable exclusion of other disorders. This study aimed to investigate the final diagnosis of patients admitted to hospital under the clinical impression of vestibular neuritis who showed no unilateral caloric paresis. Forty-five patients who visited the emergency department with isolated acute spontaneous vertigo were included...

Reversible cerebral vasoconstriction syndrome (RCVS) combined with posterior reversible encephalopathy syndrome (PRES) is a rare complication in patients treated with immunosuppressants. A 52-year-old male patient presented with seizures after heart transplantation. The patient was suspected of having PRES on brain images. Despite the strict blood pressure control, the patient presented with altered mentality and the brain images showed a newly developed large acute infarction. Digital subtraction angiography (DSA) revealed the classic "sausage on a string" appearance of the cerebral arteries - potential feature of RCVS...

While Vagus Nerve Stimulation (VNS) is proven to be a safe and effective adjunctive therapy in the general population with medically intractable seizures, little is published about its implantation during pregnancy. Here we illustrate the case of a 21year old primigravid woman with medically refractory seizures who underwent safe and successful VNS implantation and immediate activation of the device in her 32nd week of pregnancy, resulting in dramatically improved seizure control and subsequent delivery of a healthy baby...

Glioblastoma multiforme (GBM) is a treatment-resistant malignancy with poor prognosis. Temozolomide (TMZ) is widely used as a first-line drug for GBM. Although this improves patient prognosis, it does not completely eradicate the tumour. Even after total surgical resection, GBM can exhibit uncontrollable invasiveness at the tumour margins owing to activation of matrix metalloproteinases (MMPs) such as MMP-2 and -9; these degrade collagen IV in the basement membrane, which normally prevents cancer invasion. TMZ induces DNA damage and activates transcription factors including c-jun, c-fos, nuclear factor-κβ, and early growth response protein-1, which have putative binding sites on the MMP-9 promoter...

This anatomical study was performed to elucidate the pertinent foraminal and lateral L5 nerve anatomy to enhance our understanding of possible neurologic causes of failed decompression surgery. Persistent extraforaminal L5 nerve compression is a possible cause of persistent symptoms following lumbosacral surgery. The amount of extraforaminal space for the L5 ventral ramus was examined in fifty adult human skeletons (100 sides). Based on morphology, the specimens were then categorized (types I-IV) on the basis of the bony space available for the nerve at this location...

Jesse Gale, Keith Small
We describe a unique case in which a retinal slippage fold after right retinal detachment surgery resulted in a contralateral monocular scotoma. The scotoma in the left visual field matched the right retinal fold in visual space. This previously undescribed phenomenon could be explained by a lack of response from visual cortical neurons receiving inputs from the redundant folded retina. This may represent a top-down plasticity in the cortical retinotopic map.

We aimed to assess the neuroprotective mechanism of monosialotetrahexosy-1 ganglioside (GM1) on focal cerebral ischemia/reperfusion (I/R) injury in rats with diabetes. A total of 54 male Wistar rats were induced with diabetes mellitus by administration of streptozotocin (STZ). The rats were then randomized into three groups, including sham group (n=18), I/R group (n=18), and GM1 group (n=18). Focal cerebral ischemia was modeled using the right middle cerebral artery occlusion method. In the GM1 group, diabetic rats were intraperitoneally administered with GM1 (15mg/kg) at 20min prior to reperfusion...

The main change of moyamoya disease (MMD) is steno-occlusion at the terminal portion of the bilateral internal carotid arteries (ICAs). Occlusion of distal portions of the bilateral vertebral arteries (VAs) in MMD has never been reported. An 18-year old female was admitted with repeated headache for 13years. Cerebral digital subtraction angiography (DSA) demonstrated occlusion of bilateral ICAs at their terminal portions, moyamoya vessels at the skull base, occlusion of bilateral distal VAs and the basilar artery (BA) fed by the tortuous collateral vessels arising from the cervical segment of VAs...
