Cellular response to TBI is a mixture of excitotoxicity, neuroinflammation, and cell death. Biomarkers that can track these lesions and inflammatory processes are being explored for their potential to provide objective measures in the evaluation of TBI, from prehospital care to rehabilitation. By understanding the pathways involved, we could be able to improve diagnostic accuracy, guide management

Posterior transdural resection of giant calcified thoracic disc herniation in a case series of 12 patients Neurosurg. Rev. (IF 2.654) Pub Date : 2020-10-16 Chiara Negwer, Vicki M. Butenschoen, Sandro M. Krieg, Bernhard Meyer
Calcified thoracic disc herniations present a rare and challenging entity. Due to the close proximity to the spinal cord and relative narrowing of the spinal canal, the optimal approach remains a matter of debate. While the transthoracic approach is usually preferred, we adapted a new technique described in 2012: the transdural posterior approach. Our aim was to evaluate its benefits in patients with

Management of large intraventricular meningiomas with minimally invasive port technique: a three-case series Neurosurg. Rev. (IF 2.654) Pub Date : 2020-10-12 Ali O. Jamshidi, Andre Beer-Furlan, Douglas A. Hardesty, Leo F. S. Ditzel Filho, Luciano M. Prevedello, Daniel M. Prevedello
The use of minimally invasive transcranial ports for the resection of deep-seated lesions has been shown to be safe and effective. To date, most of the literature regarding the tubular retractors used in brain surgery is comprised of individual case reports that describe the successful resection of deep-seated lesions such as thalamic pilocytic astrocytomas, colloid cysts in the third ventricle, hematomas

Cranial bone flap resorption—pathological features and their implications for clinical treatment Neurosurg. Rev. (IF 2.654) Pub Date : 2020-10-12 Jennifer Göttsche, Klaus C. Mende, Anastasia Schram, Manfred Westphal, Michael Amling, Jan Regelsberger, Thomas Sauvigny, Michael Hahn
Cranioplasty following decompressive craniectomy (DC) has a primary complication when using the autologous bone: aseptic bone resorption (ABR). So far, risk factors such as age, number of fragments, and hydrocephalus have been identified but a thorough understanding of the underlying pathophysiology is still missing. The aim of this osteopathological investigation was to gain a better understanding

Cervical spine manifestations of rheumatoid arthritis: a review Neurosurg. Rev. (IF 2.654) Pub Date : 2020-10-10 Nathan A. Shlobin, Nader S. Dahdaleh
Rheumatoid arthritis (RA) is a progressive autoimmune inflammatory disease affecting 1% of the population with three times as many women as men. As many as 86% of patients suffering from RA have cervical spine involvement. Synovial inflammation in the cervical spine causes instability and injuries including atlantoaxial subluxation, retroodontoid pannus formation, cranial settling, and subaxial subluxation

Outcomes of deep brain stimulation surgery for substance use disorder: a systematic review Neurosurg. Rev. (IF 2.654) Pub Date : 2020-10-10 Omron Hassan, Sheshanna Phan, Nicole Wiecks, Christian Joaquin, Vladimir Bondarenko
Long has the standard of care for substance use disorder (SUD) been pharmacotherapy, psychotherapy, or rehabilitation with varying success. Deep brain stimulation (DBS) may have a beneficial reduction in the addiction-reward pathway. Recent studies have found reduced relapse and improvements in quality of life following DBS stimulation of the nucleus accumbens. We aim to identify positive outcomes
