The efficacy and safety of surgery for patients with primary pontine hemorrhage (PPH) remain debatable. Twenty-eight consecutive patients with huge upper PPH were included in this study. They underwent surgical management through a subtemporal approach between January 2009 and October 2013. We analyzed clinical and radiological parameters to assess the patient outcomes. The near-complete (>90%) evacuation rate was 67.9%, and there was no surgery-related death. The overall survival rate at 3 months was 64...

Cranial-nerve non-invasive neuromodulation (CN-NINM) through the tongue has been proposed as an adjuvant intervention to improve efficacy of rehabilitation. However, CN-NINM effects have only been explored in multiple sclerosis and stroke populations. In this report we used CN-NINM during a 2-week (2 × 1.5 h sessions daily) physiotherapy program for the rehabilitation of a 57 y/o woman presenting with balance and gait impairments after a surgical resection of a fourth ventricular ependymoma. Clinical and instrumented balance and gait assessments showed improved performance in all tests and without adverse effects This study shows the beneficial effects and feasibility of combined physiotherapy and CN-NINM in this patient...

In a subset of glioblastoma (GBM) patients, the differentiation between tumor progression and tumor pseudoprogression (PsP) is challenging. This case describes a male patient suffering from isocitrate dehydrogenase 1 (IDH1) mutant GBM who demonstrated an increasing contrast-enhancing (CE) lesion on a cranial magnetic resonance imaging (cMRI) scan 8 months after radiochemotherapy. In accordance with the response assessment in neuro-oncology (RANO) criteria, the cMRI lesion was classified as recurrent tumor, although 18 F-fluoroethyl-L-tyrosine positron emission tomography (18 F-FET-PET) did not indicate vital tumor tissue...

Intracranial aneurysm (IA) is a common lesion which often present asymptomatic until the time of rupture and result in subarachnoid hemorrhage (SAH). The pathogenesis of IA formation is complex and is influenced by both genetic and environmental risk factors. For exploring the detailed molecular and cellular mechanisms involved in the pathogenesis of IA, recent studies indicated inflammatory pathways and their genetic variants may as potential biomarkers. In this study, functionally relevant polymorphisms in the toll-like receptor 4 (TLR4) were screened in 330 IA patients and 313 controls from a Han Chinese population...

WHO surgical safety checklist has been proven to reduce postoperative infections in several studies. The aim of our study was to focus on surgical site infections (SSIs) after neurosurgical operations, and to determine whether the checklist implementation would have an impact on the reported SSIs. We used hospital-acquired infection (HAI) register to evaluate the effects of WHO surgical safety checklist in neurosurgery. The HAI register was searched for superficial and deep SSIs, deep organ SSIs, infections following orthopaedic implantation, and other surgical infections of 4678 neurosurgical patients operated on between 2007 and 2011...

Central neurocytoma (CN) has long been regarded as a neuronal tumor based on the immunohistochemical expression of synaptophysin and the ultrastructural observation of neurosecretory granules, neurites, and synapses. Having diagnosed 11 CNs at our institution over the past thirty years, we set out to conduct an immunohistochemical study to assess the expression profile of neuronal markers across our cases. Markers of interest included synaptophysin, alpha-synuclein, chromogranin, neurofilament, and calretinin...

Despite the recent advent of neuro-radiographic techniques, creating a 'perfect' human brain atlas providing precise and consistent images with minimal distortion is practically difficult. In this study, we created a new human brain atlas from cadaveric brains with serial sections of 50 μm thickness covering the entire basal ganglia. Human cerebral hemispheres were obtained from 10 donated cadavers and fixed in 10% formalin solution, cut in a block measuring 50 mm × 30 mm × 50 mm around the midpoint of the anterior and posterior commissures and frozen at -40 °C...

In patients with Long QT Syndrome (LQTS), mutations in the potassium channel KCNH2 gene increase seizure susceptibility with missense mutations involving the pore region of the gene acting as a positive predictor of seizures. Seizures are less commonly reported in patients with carboxyl (C')-terminus mutations. This case report describes a young man who presented with syncope followed by a first seizure and was found to have LQTS caused by a pathogenic carboxyl-terminus deletion/frameshifting mutation of the KCNH2 gene...

Most patients with cerebral venous sinus thrombosis (CVST) treated with anticoagulation have good outcomes. We examined which factors were associated with poor outcomes after treatment. We retrospectively reviewed patients ≥18 years old who were diagnosed with CVST between 1997 and 2015. Good (modified Rankin score [mRS] ≤2) and poor outcomes were dichotomized. Demographic, historical, clinical, imaging, and treatment characteristics were compared. Eighty-nine patients received treatment for CVST (52...

Digital subtraction angiography (DSA) is the gold standard for diagnosing vascular malformations; however, difficulties are associated with visualizing the angioarchitecture of arteriovenous fistulas at the craniocervical junction (CCJ AVFs) using DSA because of their complex regional neurovascular anatomy. The present study evaluated the application of 3-dimensional computer graphics (3D CG) to the surgical planning of CCJ AVFs. Six patients with CCJ AVFs who underwent microsurgery and/or endovascular treatment were included...

Klippel-Feil syndrome (KFS) is defined as congenital fusion of two or more cervical vertebrae resulting from a segmentation failure in the developing spine. According to Samartzis et al., the most commonly fused segments are found at C2/3 (74.1%) and C6/7 (70.4%). In patients with C2/3 fusion, especially when there is additional C1 occipitalization, several secondary anomalies including atlantoaxial dislocation (AAD), basilar invagination (BI), Chiari malformation, and syringomyelia can be identified. In this report, we present a case of a 12-year-old patient with C2/3 and occipitalization and a "Full-Spectrum" presentation of associated CVJ abnormalities including C0/1 fusion, AAD, BI, Chiari malformation, syringomyelia, myelopathy and cranial neuropathy received neurological decompression of the cervico-medullary junction by posterior reduction of the AAD and reconstruction of her CVJ using an unconventional hybrid construct due to a high-riding right vertebral artery in C2...

We report a 58-year-old woman with slowly progressive facio-scapulo-peroneal muscle weakness due to congenital nemaline myopathy (NM) caused by a novel ACTA1 mutation (c.118A>G, p.Met271Val). In adult patients, congenital NM should be distinguished from sporadic late-onset nemaline myopathy (SLONM), which is a treatable acquired muscle disease often associated with monoclonal gammopathy or HIV infection. Both congenital NM and SLONM are characterized by the presence of nemaline rods in muscle. The patient's clinical history of difficulty running since childhood and weakness in other family members favored a congenital NM...
