Accuracy of the methods used to estimate glomerular filtration rate compared to 24-hour urinary creatinine clearance in patients with chronic spinal cord injury.

Objective: To compare the accuracy of glomerular filtration rate (GFR) estimation by 24-hour urinary creatinine clearance with GFR estimation by the Modification of Diet in Renal Disease (MDRD) equation, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation, the Mayo Clinic Quadratic equation (MCQE), and the modified Cockcroft-Gault formula in patients with spinal cord injury (SCI).

Design: Cross-sectional study.

Participants: Fifty-nine consecutive subjects, who were admitted to our hospital SCI rehabilitation and no additional acute medical disorders, were enrolled in this study.

De novo formation of brain tumors in pediatric population following therapeutic cranial irradiation.

Purpose: Tumors of central nervous system (CNS) are accounted as the second most common tumors in childhood (21% of all cancers) following hematologic malignancies. The patients can suffer more than one cancer in their lifetime, and radiotherapy is claimed for de novo formation of a new tumor in years after treatment of an initial tumor.

Methods: We have retrospectively analyzed our database for defining radiotherapy-related de novo brain tumors operated in between January, 2000 and August, 2012.

In vivo application of poly-3-hydroxyoctanoate as peripheral nerve graft.

Objective: This study aims to investigate the degree of biocompatibility and neuroregeneration of a polymer tube, poly-3-hydroxyoctanoate (PHO) in nerve gap repair.

Methods: Forty Wistar Albino male rats were randomized into two groups: autologous nerve gap repair group and PHO tube repair group. In each group, a 10-mm right sciatic nerve defect was created and reconstructed accordingly.

Isolated paralysis of glossopharyngeal and vagus nerve associated with type II occipital condyle fracture: case report.

Introduction: Occipital condyle fractures (OCFs) can occasionally be complicated with lower cranial nerve palsies.

Discussion: Isolated 9th and 10th cranial nerve palsies following OCF are very rare. To our knowledge, we report the first case of an early onset of 9th and 10th cranial nerve palsies with an early full recovery in short period of time and discuss the probable mechanism of isolated nerve palsy in the light of the relevant literature.

Evaluation of the toxicity of onyx compared with n-butyl 2-cyanoacrylate in the subarachnoid space of a rabbit model: an experimental research.

Introduction: The toxic effects of onyx, its solvent dimethyl sulphoxide (DMSO), and n-butyl 2-cyanoacrylate (NBCA) were evaluated after infusion into the subaracnoid space of a rabbit model.

Methods: Each of the two various concentrations of onyx, pure DMSO, NBCA, and normal saline solution were percutaneously infused into the pontocerebellar cisternae of 39 domestic male albino rabbits, after which, the brain stems and medial cerebellar tissues were harvested for biochemical and histopathological studies.

Results: The specimens infused in various concentration of onyx, DMSO, and NBCA showed neural tissue necrosis and edema with inflammatory cell infitration in the acute stage.

Ruptured aneurysm at the perforating artery supplying the insula: case report.

Objective: Aneurysms originating from perforating branches of the middle cerebral artery are quite rare. Most of them arise from the lenticulostriate arteries, frequently located within the basal ganglia. We report a perforating artery aneurysm that was entirely embedded within the limen insulae.

Aspiration or capsule excision? Analysis of treatment results for brain abscesses at single institute.

Aim: Aspiration of the abscess cavity versus excision of capsule are still in debate for the capsulated, large, superficially located abscesses.

Material And Methods: Twenty patients who had large, solitary, capsulated, and superficially located lobar abscesses were analyzed retrospectively to compare the efficiency of two different surgical approaches and their impact on postoperative antibiotic use and the length of hospital stay.

Results: Nine patients underwent the capsule excision and 11 patients had the aspiration of their abscesses.

Spontaneous resolution of syringomyelia without Chiari malformation.

A 30-year-old woman presented with a cervical syrinx manifesting as hemihypesthesia. Neuroimaging found no evidence of Chiari malformation or tight cisterna magna. Serial magnetic resonance imaging studies over a 6-year period demonstrated spontaneous and complete resolution of the syrinx accompanied by an asymptomatic clinical course.
