Analysis and Differences of the Neurosurgical Complications During COVID-19 Pandemic.

Objectives: The objective of the study was to analyze the complications of neurosurgical operations during the COVID-19 pandemic by comparing them with the complications observed in the pre-pandemic period.

Methods: Two groups were formed: (1) Patients who were operated in the 5-month period of the pandemic (March-July 2020) and (2) those who were operated the same operations in the same period 1 year before (March-July 2019). Demographics, characteristics, medical follow-up data, complications, and outcome compared between the groups.

Adding Expansile Duraplasty to Posterior Fossa Decompression May Restore Cervical Range of Motion in Grade 3 Chiari Malformation Type 1 Patients.

Background: Few studies have assessed the effect of Chiari malformation type 1 (CM-1) surgical decompression on cervical lordosis and range of motion (ROM). We aimed to assess the effect of expansile duraplasty on postoperative cervical mobility and spinal stability.

Materials And Methods: This was a single-center retrospective review of prospectively collected data.

Reduction of lesion in injured rat spinal cord and partial functional recovery of motility after bone marrow derived mesenchymal stem cell transplantation.

Aim: This study aimed to analyze the effect of rat bone marrow-mesenchymal stem cells (rBM-MSCs) delivery on lesion site after spinal cord injury, and to observe the functional recovery after transplantation.

Material And Methods: MSCs were isolated from rat femurs and tibias. The experimental rat population was divided into four groups: only laminectomy (1); laminectomy+trauma (2); laminectomy+trauma+PBS (3); laminectomy+trauma+MSCs (4).

Comparison of effectiveness of facet joint injection and radiofrequency denervation in chronic low back pain.

Aim: The study was conducted to compare the clinical effectiveness of FJ injections (FJI) and FJ radiofrequency (FJRF) denervation in patients with chronic low back pain.

Material And Methods: This study included 100 patients; 50 in FJI 50 in FJRF group. VNS, NASS and EQ-5D were used to evaluate the outcomes.

Transforaminal epidural steroid injection via a preganglionic approach for the treatment of lumbar radicular pain.

Aim: To evaluate the effectiveness of transforaminal epidural steroid injection (TFESI) for lumbar radiculopathy with respect to effect of injection levels, gender, and age group.

Material And Methods: Hundred-fifty-three consecutive patients who underwent to lumbar TFESI were enrolled. The outcomes were measured by using a visual numeric scale (VNS), NASS and EQ-5D.

Trigeminal ganglion neuron density and regulation of anterior choroid artery vasospasm: In a rabbit model of subarachnoid hemorrhage.

Background: Subarachnoid hemorrhage (SAH) is associated with severe vasospasm caused by a variety of neurochemical mechanisms. The anterior choroid arteries (AChAs) are innervated by vasodilated fibers of the trigeminal ganglion (TGG). The goal of this study was to determine whether there is a relationship between the neuron density of the TGG and the severity of AChAs vasospasm with SAH.

Role of degenerated neuron density of dorsal root ganglion on anterior spinal artery vasospasm in subarachnoid hemorrhage: experimental study.

Background: The spinal arteries are innervated by several systems that contribute to the control of spinal cord blood flow. The sensory fibers of upper cervical nerves have vasodilatatory effect on the anterior spinal arteries (ASA). Subarachnoid hemorrhage (SAH) causes severe vasospasm by various neurochemical mechanisms.

Primary osteolytic intraosseous meningioma of the frontal bone.

Almost 1-2% of meningiomas are lesions described as ectopic or extradural meningiomas. Primary intraosseous meningiomas are a rare form of intra-bone tumours that account for approximately 67% of extradural meningiomas. A 41-year-old male patient presented with a headache and a bulge at the right frontal region.

Linezolid treatment of shunt-related cerebrospinal fluid infections in children.

Object: The emergence of multidrug-resistant bacteria as a cause of ventriculoperitoneal (VP) shunt infection is a disconcerting phenomenon that often requires the use of alternative antimicrobial agents due to resistance against commonly used medications. Linezolid, a member of a new class of antimicrobial agents, has good activity against virtually all important gram-positive pathogens, including multidrug-resistant gram-positive pathogens. The object of this article is to report a single-center experience with linezolid treatment in 6 young patients with VP shunt infections caused by drug-resistant strains.

Neurosurgery is a profession.

At present, the rapid advances in neurosurgical knowledge and technology are putting increased pressure on neurosurgeons to process huge quantities of information, with requirements for continuous learning and updating knowledge and skills which are time-consuming but essential. All these changes to the venerated status quo of neurosurgical practice have created an environment that may have a negative impact on neurosurgical professional behaviour. As a result, it may be that neurosurgeons find it increasingly difficult to meet their responsibilities to patients.

Imaging features of unusual intracranial cystic meningiomas.

Objective: To describe the imaging features of unusual intracranial cystic meningiomas in infants and adults.

Methods: We retrospectively reviewed the magnetic resonance and computed tomography findings for 2 female patients and 3 male patients, ranging in age from 1 to 73 years (median 41 years), with histopathologically proven cystic meningioma.

Result: Although cystic meningiomas usually appear as solid and cystic masses, they may present as a mainly multicystic lesion.
