Fiber-Optic Intracranial Pressure Monitoring System Using Wi-Fi-An In Vivo Study.

Background: Continuous invasive monitoring of intracranial pressure (ICP) is essential in neurocritical care for surveillance and management of raised ICP. Fluid-based systems and strain gauge microsensors remain the current standard. In the past few decades, several studies with wireless monitoring were developed aiming to reduce invasiveness and complications.

The impact of traumatic herniated discs in cervical facets dislocations treatments: systematic review and meta-analysis.

Background: Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations.

The surgical treatment of subaxial acute cervical spine facet dislocations in adults: a systematic review and meta-analysis.

Adult cervical spine traumatic facet joint dislocations occur when excessive traumatic forces displace the vertebrae's facets, leading to loss of joint congruence. Reduction requires either cranial traction or open surgical procedures. This study aims to appraise the effects of different surgical techniques in the treatment of subaxial cervical spine acute traumatic facet blocks in adults.

Correlation of Intraoperative Neurophysiological Parameters and Outcomes in Patients with Intramedullary Tumors.

Introduction: Intramedullary spinal cord tumors (IMSCT) account for about 2%-4% of all central nervous system tumors. Surgical resection is the main treatment step, but might cause damage to functional tissues. Intraoperative neuromonitoring (IONM) is an adopted measure to decrease surgical complications.

The effect of filum terminale sectioning for Chiari 1 malformation treatment: systematic review.

Purpose: Symptomatic Chiari type I malformation (CM) is treated with posterior fossa decompression with/ without duroplasty. Few authors suggested cerebellar tonsil caudal migration due to a supposed "caudal traction" of cranial nerve structures in a so-called occult tethered cord syndrome. For these authors, filum terminale (FT) sectioning may improve CM symptoms.

Intraoperative Neurophysiological Monitoring in Spine Surgery: A Systematic Review and Meta-Analysis.

Study Design: Systematic literature review and meta-analysis.

Objective: The objective of this systematic literature review was to evaluate if intraoperative neurophysiological monitoring (IONM) can prevent neurological injury during spinal operative surgical procedures.

Summary Of Background Data: IONM seems to have presumable positive effects in identifying neurological deficits.

Spontaneous intracranial epidural hematoma during rivaroxaban treatment.

According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xareltor. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull.

Outcome following lumbar disc surgery: the role of fibrosis.

Background: Failed-back surgery syndrome remains a challenge for spinal surgeons. It can be related to several causes, including poor surgical indication, misdiagnosis, surgical technique failure, spondilodiscitis and fibrosis. Fibrosis has been associated with a poorer outcome in lumbar disc surgery, although its role in the generation of symptoms is not yet clear.

Primary filum terminale ependymoma: a series of 16 cases.

Filum terminale ependymomas are slow growing tumors of the cauda equina with a high incidence in young adults. Although a complete microsurgical resection can lead to a cure, recurrence is not uncommon. Sixteen cases of filum terminale ependymomas treated at the Instituto de Neurologia de Curitiba were analyzed.

Is preoperative occupation related to long-term pain in patients operated for lumbar disc herniation?

Lumbar disc herniation (LDH) is a common cause of back and sciatic pain. When clinical treatment fails, surgery may be indicated in selected patients. Although surgery is effective in most cases, some of these patients may have a poor outcome.

Distal posterior inferior cerebellar artery aneurysm: case report.

The majority of posterior inferior cerebellar artery (PICA) aneurysms are usually found on the bifurcation of the vertebral artery (VA) - PICA junction. Aneurysms arising from more peripheral PICA segments named distal PICA aneurysm are uncommon. The major clinical manifestation is that of an intracranial bleeding and the site of hemorrhage is related to the PICA segment originating the aneurysm.

[Comparative analysis of human brain slices with three different staining techniques].

Studying neuroanatomy at brain slices with gray matter staining techniques has several advantages. More often, the models described by Barnard, Robert and Brown, Mulligan, and Green are used. The aim of this study was to identify which of them achieves the best results on differentiation between the gray and the white matter.

[Cerebral and systemic venous thrombosis associated to prothrombin G20210 mutation: case report].

Cerebral venous thrombosis is a clinical condition of difficult diagnosis, and poor prognosis when treatment is not started early. There is a long list of causes, and hereby we describe a case associated to prothrombin G20210 mutation. A 53-year-old man, white, was admitted with status epilepticus.

Peritoneal dissemination from central neurocytoma: case report.

Objective: Central neurocytoma is a low grade tumor of neuroglial origin and a relatively new histological entity. Only a few cases have been reported and its biological behavior is still uncertain. Some cases have shown an aggressive behavior (local recurrence, malignant dedifferentiation or CSF dissemination) and challenged the initial view of its relative benignity.
