Intramedullary Schwannoma in the Cervical Region: A Case Report.

Intramedullary schwannomas are a type of benign spinal cord tumor that originates from the Schwann cells of the nerve sheath. They are relatively rare and typically occur within the spinal cord itself, rather than in the surrounding tissue. Treatment options for cervical intramedullary schwannomas include surgical removal of the tumor, radiation therapy, and observation.

All aspect of toxic effect of brilliant blue and sunset yellow in Allium cepa roots.

Substances added to food are considerable for survival and are the oldest technologies used in preservation, sweetening and coloring. This work was conducted to evaluate the toxicity of the food additives sunset yellow (SY) and brilliant blue (BB) on Allium cepa root meristematic cells. Control and treatment groups were created from germinated roots.

Measurement of the distribution of radiation in the area surrounding the target mass using optically stimulated luminescence technique.

The scattered doses received by the area surrounding the target that has been subjected to x-rays were investigated. Two experiments were carried out: 1- AlO: C was used as dosimeter and the luminescence counts was measured using both the RisØ TL/OSL system and an ion chamber. 2- BeO aliquots were used and the counts were read using the IBEOX/OSL system.

Surgical management of an osteoblastoma involving the entire C2 vertebra and a review of literature.

Purpose: The purpose of this study was to evaluate the surgical management of an osteoblastoma involving the entire C2 vertebra.

Materials And Methods: A 14-year-old girl presented with unbearable neck pain. Her medical history was unremarkable.

Pediatric intervertebral disc calcification.

Idiopathic calcification of the intervertebral disc is a rare condition in childhood, of unknown etiology. Calcifications are occasionally discovered on routine radiological examination, or on investigation of nonspecific symptoms such as neck pain, torticollis, fever, and radiculopathy. We report a case of a 7-year-old boy with intervertebral disc calcification.

Cervical eosinophilic granuloma and torticollis: a case report and review of the literature.

Eosinophilic granuloma (EG) is a benign and solitary bony lesion of unknown etiology, which typically affects children: 90% of patients are between the ages of 5 and 15 years. EG, a variant of histiocytosis X, is a rare disease causing destructive bony lesions of the cervical spine in children. This report describes the case of a 5-year-old boy with torticollis who presented to the Emergency Department and was found to have EG of C6.

Disseminated nocardiosis due to unusual species: two case reports.

Pulmonary nocardiosis is the major clinical manifestation of human nocardiosis and disseminated infection can be seen in immunocompromised patients. N. asteroides is the predominant pathogen associated with disseminated diseases.

Surgical treatment of distal anterior cerebral artery aneurysms with horizontal head position.

Objective: In the surgery for a distal anterior cerebral aneurysm which is applied with a vertical head position, the dome of the aneurysm makes it difficult the expose the neck and the proximal artery. This study was performed to evaluate the applicability of the alternative contralateral interhemispheric approach with a horizontal head position for clipping these aneurysms.

Method: The head of the patient was placed in the horizontal position such that the aneurysm side remained at the top and then tilted 45 degrees superiorly.

Cervical spondylotic myelopathy and radiculopathy treated by oblique corpectomies without fusion.

Oblique corpectomy (OC) is an alternative technique for the resection of spondylotic spurs ventral to the cervical spinal cord contributing to cervical spondylotic myelopathy (CSM) and cervical spondylotic radiculopathy (CSR). To evaluate the efficacy of OC for the treatment of cervical spondylotic myeloradiculopathy, we reviewed our experience with OC. Twenty-six patients, 18 males and 8 females, were studied.

Transbasal approaches: surgical details, pitfalls and avoidances.

Lesions involving the anterior skull base and sphenoclival region are difficult surgical problems. This paper presents surgical details, pitfalls, avoidances and our experiences in the surgical treatment of lesions of the anterior skull base using neuronavigation. Between 1999 and 2003, 33 patients with pathology of the anterior skull base were operated on via the traditional transbasal and the extended transbasal approach.

Clivus fractures: clinical presentations and courses.

Fractures in the clivus region are usually associated with blunt head trauma. They may cause many cranial nerve deficits and vascular complications. The mortality rate is high because of brainstem trauma or vertebrobasilar occlusion.

Growing skull fracture of the orbital roof: Report of two cases and review of the literature.

In this report, the authors describe two cases of growing fracture of the orbital roof. The aim is to draw attention to this rare complication and discuss the role of three-dimensional computed tomography in radiological findings and surgical planning. Relevant literature is also reviewed.

Effects of mexiletine, ginkgo biloba extract (EGb 761), and their combination on experimental head injury.

Lipid peroxidation (LP) and brain edema are important factors that produce tissue damage in head injury. The purpose of this study was to investigate the effect of mexiletine, gingko biloba extract (EGb 761), and their combination on LP and edema after moderate head trauma. Forty rats were randomly and blindly divided into four groups of ten animals each: control group (bolus injection of physiological saline), mexiletine group (50 mg/kg per injection), EGb 761 group (30 mg/kg per injection), and mexiletine plus EGb 761 group (50 mg/kg and 30 mg/kg per injection, respectively).
