Spontaneous Spinal Epidural Hematoma During Pregnancy: A Case Report.

Spontaneous spinal epidural hematoma (SSEH) during pregnancy is an extremely rare neurological emergency, often presenting with sudden neck pain and progressive limb weakness. This report describes a 26-year-old pregnant woman at 26 weeks of gestation who developed paraplegia and severe muscle weakness without prior trauma. MRI revealed a cervical epidural hematoma, leading to an emergency C6 and C7 laminectomy.

The Effect of Biomarkers and Optic Nerve Sheath Diameter in Determining Mortality in non-Traumatic Subarachnoid Hemorrhage.

Aim: Although radiological methods are sufficient for the diagnosis of spontaneous subarachnoid hemorrhage (SAH), additional biomarkers are needed to predict prognosis. The aim of this study was to investigate the effects of serum S100B protein, Glial Fibrillary Acidic Protein (GFAP) levels and, Optic Nerve Sheath Diameter (ONSD) on mortality and clinical severity in patients with spontaneous SAH.

Materials And Methods: Fifty-six patients who were diagnosed with SAH after first evaluation in the emergency department (ED) were included in the study group; Forty-six patients who were admitted to the ED with headache of non-intracranial etiology, were included as the control group.

Shoulder traction device for enhanced conventional fluoroscopy during cervical spine operations.

Conventional biplanar fluoroscopic imaging of the cervical spine is commonly used during cervical spinal surgery. We designed an intraoperative traction device to prevent shoulder superimposition on the cervical fluoroscopic imaging. During surgery at the stage of fluoroscopic examination, an operator can apply traction via the traction band of the device.

Use of topical landmarks for percutaneous projection of intracranial tumors for neurosurgical oncology.

Aim: The objective of this study was to introduce a surgical navigation method which provides a safe, quick and effective access to cortical and subcortical tumors, along with a review of other methods in use for this purpose.

Material And Methods: 53 patients have been operated using this technique. The area overlying the tumor is shaved and one half of a smoothly cut hazelnut is taped on the skin.

Hippocampal cell loss after an anterior and posterior anastomotic vein occlusion model in rats.

Estimation of the cell number after cortical venous ischemia/infarction induced by anterior and posterior anastomotic veins occlusion in a rat model is very important. Twenty male Sprague-Dawley rats were used in this experiment. Small burr-holes were made over the anterior (the crossing point of the line drawn from the posterior border of the orbital rim and the line drawn along the para-midline to the superior sagittal suture) and posterior (just inferior point of the posterior ending of the zygomatic arch) anastomotic veins.

Usefulness of S100B protein in neurological disorders.

In recent years, there has been an increased interest in the clinical use of brain markers. The S100B is a calcium-binding peptide and is used as a parameter of glial activation and/or death in many disorders of the central nervous system (CNS). It plays important roles in normal CNS development and recovery after injury.

The segments and the inferior boundaries of the odontoid process of C2 based on the magnetic resonance imaging study.

Aim: The aims of this clinical study were to describe the segments and the inferior boundaries of the odontoid process as regards the embryological development of C2 based on the magnetic resonance imaging finding.

Material And Methods: Cranial and cervical magnetic resonance images including occiput, C1, and C2, and those obtained for different reasons such as evaluation of cranial and upper cervical pathology were re-evaluated for this study. Synchondroses around the odontoid process were accepted as the boundaries between the neural arch and the body of C2.

Ultrasound examination in the surgical treatment for upper extremity peripheral nerve injuries: part I.

Aim: The aim of this clinical study was to evaluate the benefits of ultrasonographic imaging in the surgical treatment of upper extremity peripheral nerve lesions.

Material And Methods: Peripheral nerves in the upper extremity were evaluated by using real-time ultrasonographic examination. The capability of ultrasonography in terms of determination the type of injury, the position of the proximal and distal nerve stumps, the presence or absence of a neuroma and perilesional scar tissue were evaluated in cases with peripheral nerve injury.
