Early management of adult traumatic spinal cord injury in patients with polytrauma: a consensus and clinical recommendations jointly developed by the World Society of Emergency Surgery (WSES) & the European Association of Neurosurgical Societies (EANS).

Background: The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies.

Methods: A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in the acute management of tSCI polytrauma patients with different specializations was established.

Management of spinal aneurysms associated with arteriovenous malformations: systematic literature review and illustrative case.

Purpose: Spinal aneurysms are rare vascular malformations, commonly associated with spinal AVMs. AVM-associated spinal aneurysms are burdened by significant morbidity. The purpose of our study is to evaluate the best treatment strategy for these uncommon vascular lesions and to report an illustrative case.

Turning tables: a war-like approach to neurosurgical emergencies in the COVID-19 era.

During the Coronavirus-disease-2019 (COVID-19) pandemic emergency, neurosurgeons may have to decide to prioritize treatments to patients with the best chance of survival, as in a war setting triage. In this paper, we discussed factors that should be considered in the perioperative period and neurocritical care management of neurosurgical patients during a pandemic emergency; in particular, we focused on the decision on whether to operate or not a patient during the COVID-19 pandemic. A multidisciplinary expert panel composed by specialists with direct experience in COVID-19 management discussed and reviewed the criteria that should be taken into account in the decision to operate or not a patient during the COVID-19 pandemic.

A rare case of intracranial malignant triton tumor arising in the middle cranial fossa: a case report and review of the literature.

We describe a rare case of intracranial malignant triton tumor (MTT) arising in the middle cranial fossa in a 74-year-old female patient who had previously been exposed to radiation in the Chernobyl disaster. The patient underwent a surgical subtotal removal of the mass and radiation therapy, but the progression-free survival was only 2.5 months and death occurred four months after the onset of symptoms.

Calpain-1 resident in lipid raft/caveolin-1 membrane microdomains plays a protective role in endothelial cells.

We are here reporting that calpain-1 is a constitutive component of a distinct lipid raft/caveolin-1 microdomain isolated from bEnd5 cells in association with endothelial nitric oxide synthase (eNOS) and heat shock protein 90 (HSP90). Perturbations in intracellular calcium concentration by Ca-ionophore A23187 or prolonged cell exposure to high glucose induce a significant decrease in the level of eNOS accompanied by a recruitment of additional HSP90 molecules at this site. In these conditions the cells are more resistant to cell death by Ca overload.

Effect of mono- or bisegmental lordosizing fusion on short-term global and index sagittal balance: a radiographic study.

Background: Sagittal balance is widely recognized as an important outcome factor in reconstructive spinal surgery for lumbar degenerative conditions. However, its role in short segmental fixation is unknown. The aim of this study was to evaluate the preoperative and short-term postoperative spino-pelvic balance after short (1 or 2 levels) lordosizing lumbar fusion for degenerative disc disease (DDD).

A rare case of osteoblastoma associated to aneurysmal bone cyst of the spine. Case report.

Osteoblastoma is a rare bone tumour. It is occasionally associated with an aneurysmal bone cyst (ABC). Several treatment strategies can be adopted.

Sinus pericranii: diagnosis and management in 21 pediatric patients.

Object: Sinus pericranii (SP) is a rare venous anomaly abnormally connecting the intracranial dural sinuses with the epicranial veins. In the present study the authors aimed to clarify this clinicoradiological entity, define the role of angiography in its preoperative assessment, and suggest a diagnostic-therapeutic flow chart for management purposes.

Methods: The authors retrospectively reviewed the clinical charts and neuroimages of 21 patients with SP.

Identification of a novel set of genes reflecting different in vivo invasive patterns of human GBM cells.

Background: Most patients affected by Glioblastoma multiforme (GBM, grade IV glioma) experience a recurrence of the disease because of the spreading of tumor cells beyond surgical boundaries. Unveiling mechanisms causing this process is a logic goal to impair the killing capacity of GBM cells by molecular targeting.We noticed that our long-term GBM cultures, established from different patients, may display two categories/types of growth behavior in an orthotopic xenograft model: expansion of the tumor mass and formation of tumor branches/nodules (nodular like, NL-type) or highly diffuse single tumor cell infiltration (HD-type).

HOXA7, 9, and 10 are methylation targets associated with aggressive behavior in meningiomas.

Meningioma is one of the most common intracranial tumors and is graded according to the World Health Organization (WHO) classification system. Although these tumors are often surgically curable, a malignant behavior also may occur in meningiomas with benign histologic profiles (WHO I). Thus, it is mandatory to identify biomolecular parameters useful to improve the classification of these tumors.
