BACKGROUND: Although percutaneous kyphoplasty (PKP) is performed to restore the vertebral body height and kyphosis in osteoporotic vertebral compression fractures (OVCFs), the regained height may be lost upon balloon deflation. This study compares PKP with its modified version (MPKP) in terms of the clinical outcomes in treating OVCFs. METHODS: Between May 2014 and March 2016, 76 patients with OVCFs were randomly assigned to two groups according to the procedure chosen: the PKP group (n=36) and MPKP group (n=40)...

BACKGROUND: A plethora of reactive cellular responses emerge immediately after a traumatic spinal cord injury (SCI), and may influence patient´s outcomes. We investigated whether serum concentrations of NSE, IL-6, GDNF and NGF reflect the acute phase responses to different etiologies of SCI, and may serve as predictive biomarkers of neurological and functional outcomes. METHODS: Fifty-two patients were admitted to the intensive care unit after SCI due to traffic accidents, falls and firearm wounds and had blood samples collected within 48 h and seven days (7-d) after SCI...

BACKGROUND: Parasellar plasmacytomas are rare tumors arising from the sellar region that should be considered in differential diagnosis for lesions involving the sella and clivus. Prior to surgical pathologic examination, parasellar plasmacytomas are often misdiagnosed as invasive pituitary adenomas or chordomas due to the similarity of clinical presentation and imaging findings. METHODS: We retrospectively reviewed 5 patients with parasellar plasmacytoma who underwent endonasal endoscopic tumor resection in Beijing Tiantan Hospital between January 2008 and January 2018...

An epidermoid cyst is a rare tumor of the cerebellopontine angle region. It usually presents with ipsilateral compressive symptoms. The contralateral trigeminal neuralgia is an unusual presentation in such cases. We did not find such case reports in the literature. Here, we report a case of 62 years old female having right cerebellopontine angle epidermoid cyst presenting with right hearing impairment and the contralateral trigeminal neuralgia. The possible mechanism leading to the contralateral trigeminal neuralgia is discussed here along with the diagnosis and the management of the case...

Acellular Nerve Allografts (ANAs) have established as a promising alternative to the autologous nerve grafts, which currently represent the gold-standard yet. This research group has recently systematically reviewed the cell-based enriching methods described in the literature for recellularization of ANAs. The effect of recellularization is a consistent improvement of peripheral neuroregeneration compared to plain ANAs. The aim of this study was to systematically review the effects on nerve regeneration when ANAs enrichment is obtained through biological/chemical and physical modification instead of cells...

OBJECTIVE: The number of patients with chronic subdural hematoma (CSDH) showing comorbidities and/or impaired activities of daily living (ADL) before the onset of CSDH has increased with the recent aging of society. The purposes of this study were to evaluate ADL worsening by comparing premorbid ADL and ADL at discharge, and to investigate the effects of pre-existing comorbidity-related clinical factors on the outcomes. METHODS: A total of 570 patients with CSDH admitted from 2006 to 2016 were studied retrospectively...

OBJECTIVE: Anterior communicating artery (ACoA) complex aneurysms are challenging to treat microsurgically. The authors report their experience with microsurgical treatment of ACoA aneurysms and examine the anatomic characteristics of these aneurysms as predictors of outcome. METHODS: The authors queried their institution's aneurysm database for records of consecutive patients treated for ACoA aneurysms via microsurgical clip ligation. Data included patient demographics and clinical/radiographic presentation characteristics as well as operative techniques...

BACKGROUD: Management of proximal middle cerebral artery (M1) aneurysm can be challenging. Because of the diversity of aneurysm morphology and location of M1 aneurysms, the surgical strategy should be tailored for each individual case and especially for the complex case. OBJECTIVE: To assess the safety and efficacy of algorithmic strategy for the management of M1 aneurysms. METHODS: A prospective single-center study of M1 aneurysms treated with microsurgery was performed...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a relatively uncommon cause of stroke in pediatric and young adult. The clinical course of CVST is also highly variable. In particular, coma has been noted as a predictor of poor outcome. The standard treatment for CVST in adults is systemic anticoagulation, which can lead to recanalization. Endovascular mechanical thrombectomy (EMT) is considered as possibly indicated in the event of failure to respond to anticoagulation or a comatose state...

BACKGROUND: Hemangioblastomas (HBMs) are benign vascular neoplasms that most commonly arise within the cerebellum. While other vascular lesions should be considered in the differential diagnosis, HBMs rarely resemble aneurysms on neuroimaging and only one case of a cerebellar HBM mimicking a posterior fossa aneurysm has been reported. Here we describe a retromedullary HBM that masqueraded as a distal posterior inferior cerebellar artery (PICA) medullary branch aneurysm. CASE DESCRIPTION: A 63-year-old asymptomatic male was incidentally diagnosed with an unruptured 3-mm left PICA aneurysm via CT angiography (CTA) during a workup for carotid stenosis...
