Endoscopic Lavage for the Treatment of Multiple Shunt Failures in Children.

Aim: To compare the efficacy of neuroendoscopic lavage (NEL) and shunt revision (SR) in the treatment of multiple shunt failures in children with hydrocephalus.

Material And Methods: The data of 56 pediatric patients who underwent surgeries for the treatment of shunt failure were retrospectively reviewed. Patients were divided into two groups, i.

Meningiomas of the Cerebellopontine Angle: Tips and Pearls for Safe Surgical Resection.

Aim: To present our series of cerebellopontine angle (CPA) meningiomas, and to provide some innovative surgical steps for safe removal of these tumors.

Material And Methods: The clinical, radiological, and surgical characteristics of 32 patients with meningioma in the CPA were retrospectively analyzed. A statistical analysis was performed to determine the factors that affect the incidence of complication.

Spontaneous migration of a bullet in the cerebrum.

Herein, we report the case of a 32-year-old man who experienced spontaneous migration of a bullet within the brain following a gunshot injury. Emergent computed tomography revealed the bullet located in the posterosuperior side of mesencephalon. During follow-up after 10 days, the neurological status of the patient had worsened.

Effects of Zinc Oxide on mRNA Expression of Genes in Brain Tissue of Rats.

Aim: To investigate the expression of the DR4, DR5, OPG, DcR1, and DcR2 in rat brain tissue.

Material And Methods: Thirty rats were used in this study. The rats were divided into three groups as the control group (n=10), tumor group (n=10), and zincoxide (ZnO) nanoparticles (NP) treatment group (n=10).

Anterior Skull Base Defects Reconstructed Using Three-Layer Method: 78 Consecutive Cases with Long-Term Follow-Up.

 Anterior skull base defects are potentially lethal and surgical treatment must be performed as soon as possible. The purpose of this study was to evaluate whether our technique is effective or not in long-term period. Retrospective chart review of all patients whose data were entered into the Hospital Registry System between 1995 and 2015.

Parieto-Occipital Interhemispheric Precuneal Approach to the Lesions of the Atrium: Experience with 66 patients.

Aim: The atrium (trigone) is the most common site for intraventricular lesions. The parieto-occipital interhemispheric precuneal approach (POIPA) is one of the particular ways to reach these lesions. The aim of this study was to draw specific attention to the surgical difficulties of these lesions and to present our experience with this operative approach.

Multicentric Dentigerous Dermoid Cyst with an Unusual Location in the Central Nervous System.

Dermoid cysts are benign and congenital ectodermal inclusions. Their occurrence in an intracranial location is quite rare. They constitute 0.

Early cyclosporin A treatment retards axonal degeneration in an experimental peripheral nerve injection injury model.

Injury to peripheral nerves during injections of therapeutic agents such as penicillin G potassium is common in developing countries. It has been shown that cyclosporin A, a powerful immunosuppressive agent, can retard Wallerian degeneration after peripheral nerve crush injury. However, few studies are reported on the effects of cyclosporin A on peripheral nerve drug injection injury.
