Clinical features and treatment strategies for vertex epidural hematoma: a systematic review and meta-analysis from individual participant data
This study aims to understand the clinical manifestations and current treatment strategies for VEDH. We searched the published literature regarding VEDH through PubMed and Google Scholar, and individual patient data (IPD) were obtained from the  eligible articles. A systematic review and IPD meta-analysis were conducted. In total, 70 patients’ individual participant data were gathered. Most patients were male (87%), and traffic-related accidents were the most common injury mechanism (49%). Approximately half the patients (47%) were neur ologically intact with nonspecific symptoms such as headache, dizziness, and...

Anaplastic gangliogliomas of the spinal cord: a scoping review of the literature
AbstractGangliogliomas (GGs) are rare, usually low-grade tumors that account for 1 –2% of all central nervous system (CNS) neoplasms. Spinal GGs are exceedingly rare (1% of all spinal tumors) and the presentation of anaplastic features in them is even rarer. According to the last World Health Organization (WHO) classification of CNS neoplasms, anaplastic GG (AGG) is classified a s a malignant neoplasm (grade III). We performed a scoping review of the literature to elucidate the epidemiology, clinical features, histopathology, treatment, and outcome of primary spinal AGGs, which, to the best of our knowledge, is the f...

Microvascular decompression for trigeminal neuralgia due to vertebrobasilar artery compression: a systematic review and meta-analysis
AbstractTrigeminal neuralgia (TN) caused by vertebrobasilar artery (VBA) compression is a rare event, reported between 2 and 6% (Linskey et al.

Admission serum high mobility group box 1 (HMGB1) protein predicts delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage
AbstractHigh mobility group box 1 protein (HMGB1) is a prototypical damage associated particle and acts as a key player in aseptic inflammation. HMGB1 appears critical for the crosstalk of a prothrombotic and proinflammatory state that is implicated in mediating and exacerbating ischemic brain injury. The role of HMGB1 in aneurysmal subarachnoid hemorrhage (aSAH) remains to be elucidated. A prospective, single blinded observational study was designed to investigate the role of HMGB1 in aSAH. Serial serum HMGB1 level quantification on admission day 0, 4, 8, and 12 was performed. Primary outcome measures were delayed cerebra...

Endoscopic third ventriculostomy before surgery of third ventricle and posterior fossa tumours decreases the risk of secondary hydrocephalus and early postoperative complications
AbstractEndoscopic third ventriculostomy (ETV) is an effective treatment for obstructive hydrocephalus (HCP) at the level of third or fourth ventricle. To date, there is no consensus regarding its role as intervention preceding the operation of tumour removal. The aim of this prospective open-label controlled study is to assess if ETV prevents secondary HCP after tumour removal and if ETV influences the early results of tumour surgery. The study was performed on 68 patients operated for tumours of the third ventricle and posterior fossa. In 30 patients, ETV was performed several days before tumour removal, while in 38 pati...

Evolution of microneurosurgical anatomy with special reference to the history of anatomy, surgical anatomy, and microsurgery: historical overview
This article reviews the evolution of microneurosurgical anatomy (MNA) with special reference to the development of anatomy, surgical anatomy, and microsurgery. Anatomy can be said to have started in the ancient Greek era with the work of Hippocrates, Galen, and others as part of the pursuit of natural science. In the sixteenth century, Vesalius made a great contribution in reviving Galenian knowledge while adding new knowledge of human anatomy. Also in the sixteenth century, Ambroise Par é can be said to have started modern surgery. As surgery developed, more detailed anatomical knowledge became necessary for treat...
