Relationship between NLR (Neutrophil/Lymphocyte ratio) value and clinical outcome in patients with external ventricular drainage due to intraventricular hemorrhage.

Background: Intraventricular hemorrhages (IVH) are common pathologies in neurosurgery practice and are associated with the worst clinical outcome among all intracranial hemorrhages. Blood in the ventricles is thought to worsen the clinical condition by triggering inflammatory processes. In recent years, NLR value is a frequently used inflammatory parameter, and there are many publications reporting that a high NLR value is an important marker in predicting the severity of inflammation.

Retrospective Evaluation of Cases Undergoing Stereotaxic Brain Biopsy.

 The aim of this study is to evaluate the demographic, radiological and histopathological findings, tumoral biomarkers, and survival rates of patients who underwent a stereotactic brain biopsy and those diagnosed with glioblastoma, metastasis, and lymphoma, and the changes in the diagnosis distribution over the years.  The patients who underwent stereotactic biopsy in our clinic between 2012 and 2020 were evaluated retrospectively. Metastasis, glioblastoma, and lymphoma cases were evaluated as three main groups and the others were excluded.

Effects of sodium fluoride on neural tube development in chick embryos.

Objective: Various environmental factors encountered in daily life are associated with the development of neural tube defects. This study aims to investigate the effects of fluoride on neural tube development in chick embryos.

Methods: A total of 60 specific pathogen-free, fertile, zero-day Leghorn-type eggs were used in the study.

The relationship between bone canal diameter and facet tropism in cases of lumbar spinal stenosis.

Objectives: Lumbar spinal stenosis (LSS) is a condition that increases in frequency with the aging of the spine and has adverse effects on the quality of life of individuals. Facet tropism (FT) refers to the difference in the orientation of the facet joints relative to each other in the sagittal plane. This situation may be due to a developmental defect or different stimuli.

Effects of tamoxifen therapy on sciatic nerve crush injury: An experimental study in rats.

Objective: This study aimed to determine the effects of tamoxifen on sciatic nerve crush injury in a rat model using histopathological, histomorphometric, and immunohistochemical approaches.

Methods: In this study, 24 male Sprague-Dawley rats aged of 5 to 7 weeks and weighing between 300 g and 400 g were used. The rats were randomly divided into 3 groups: control (group C), sciatic nerve injury (group SNI), and sciatic nerve injury with tamoxifen (group SNT).

Three region spinal decompression in the same session: a case report.

Background And Importance: Multiregional spinal stenosis [tandem spinal stenosis (TSS)] is not rare but operating on multiple regions at the same sitting is. Decompression of cervical and lumbar spine in the same session has a frequency of 5-25% all TSS cases, the most frequent one is TSS. Decompression in three different regions is so rare that there is only one case in the literature.

Clinical and radiological outcomes after correction of degenerative lumbar scoliosis with dynamic stabilization (with the help of a rigid rod); and describing an alternative technique.

Sharing clinical and radiological results in patients with degenerative lumbar scoliosis (DLS) treated surgically with dynamic system and describing an alternative technique for scoliosis correction. Between 2013 and 2018, 48 patients with flexible degenerative lumbar scoliosis (DLS) were operated with dynamic stabilization with Polyetheretherketone Rod (PEEK rod) after rigid rod application. Preoperative and postoperative scoliosis angles (standing and supine) were statistically compared.

Any Instrument in a Surgeon's Hand can be Fatal: Unusual Iliac Artery Injury in Lumbar Spinal Deformity Surgery.

Background: Vascular complications, which we rarely encounter during lumbosacral stabilization surgeries, can be life-threatening if they are not treated quickly. These arterial injuries occur during screw insertion. Our presentation with the common iliac artery injury during the decortication process in transverse processes with the "pedicle awl" will be the first case in the literature to our knowledge.

Spinal anesthesia in surgical treatment of lumbar spine tumors.

Objective: This study aims to show the feasibility of spinal anesthesia in lumbar spinal tumor surgery; share our data and experience.

Patients And Methods: A retrospective review of 14 patients with high risk for general anesthesia due to severe comorbidities was carried out. Patients who underwent surgeries under spinal anesthesia for lumbar vertebral column or spinal cord tumors at a single center between 2007-2019 were evaluated.

Radiological and clinical comparisons of the patients with rheumatoid arthritis operated with rigid and dynamic instrumentation systems due to lumbar degenerative spinal diseases.

Background: It is extremely difficult to treat spine disorders with stabilization in patients with rheumatoid arthritis. Because revision rates are significantly higher in rigid stabilization. To date, there is no data about patients with rheumatoid arthritis treated with dynamic stabilization.

Acute spinal epidural hematoma: A case report and review of the literature.

Spinal epidural hematoma (SEH) is a rare but a significant cause of spinal cord compression and neurologic deficits. Its etiology is usually unknown and requires emergency intervention. The present study aims to review the clinical significance, treatment strategies and clinical outcomes of traumatic SEH with a rare case presentation.

Polymethylmetacrylate Cement Augmentation of the Coccyx (Coccygeoplasty) for Fracture: A Case Report.

Background: Coccydynia is a painful condition of the sacrococcygeal region, with symptoms associated with sitting and rising from a seated position. It is frequently related to trauma and idiopathic causes, and the pain is mostly chronic. Percutaneous vertebroplasty and sacroplasty are the methods that are widely used for treating compression fractures and sacral insufficiency fractures, respectively.

Morphometric analysis of cervical intervertebral disc space to reduce neural complications during anterior approaches to the cervical spine.

Background: Although neurovascular complications rarely occur during surgical procedures, they have serious consequences. We reviewed the limits of safe surgery to decrease the possibility of neurovascular injuries.

Methods: Four measurements were performed for each patient at the vertebral levels adjacent to the intervertebral discs at C3-C4, C4-C5, C5-C6, and C6-C7.

Effect of L-Arginine Therapy on Vasospasm: Experimental Study in Rats.

Objective: Cerebral vasospasm occurring after subarachnoid hemorrhage is a serious cause of morbidity. Cerebral vasospasm-related studies aim to prevent complications after subarachnoid hemorrhage. Nitric oxide affects brain blood flow and local vascular hemodynamics.

Comparative morphometric analysis of congenital and acquired lumbar spinal stenosis.

Lumbar spinal stenosis is one of the primary causes of low back pain and is one of the primary causes of spinal surgery. Lumbar spinal stenosis is classified as congenital, acquired and a combination of both. Although the symptoms of both groups are similar, their etiology and radiographic features demonstrate some differences.

Complicated fronto-orbital mucopyocele presenting with proptosis: a case report.

Mucoceles are cystic lesions of the paranasal sinuses which develop as a result of accumulation of mucous secretion due to obstruction of the ostium of the sinuses. Despite their benign behavior, they may enlarge progressively and project into adjacent structures by destructing the bony walls of the sinuses. Frontal mucoceles may get infected and extend towards orbital cavity and compress the orbit by eroding the bony walls of the orbital cavity.

Solitary plasmocytoma of the skull.

A 63-year-old man presented with a 4-month history of a slowly growing soft mass at his right parieto-occipital region. Neuroradiological examinations revealed an osteolytic extradural tumour of the skull vault. The outer and inner tables of the skull were partially destroyed by the tumour, but the dura was not involved.
