Objective: Acute ischemic stroke is caused by a reduction in cerebral blood flow, leading to brain and subsequent cell death. The therapeutic options available for this condition are limited. inflammatory response associated with the injury may influence outcomes of stroke. Clarithromycin widely used antibiotic medical practice. This study aimed investigate effect clarithromycin on injury. Methods: In study, 38 Sprague Dawley female rats were divided into four main groups: pure control...

Thoracic level localization in the treatment of thoracic spine problems is more challenging than other spinal regions. The purpose this study was to prove reliability pedicular needle placement under computed tomography guidance before surgery and reduce margin error, time operating room radiation exposure during cord surgery. Fourteen patients undergoing posterior aproach and/or related lesions were investigated. Spinocaths placed CT guidance, into pedicle relevant vertebra, at same day or...

Study Design. Report of three cases. Objectives. To describe a rare location intervertebral disc migration. Summary Background Data. Migration sequestered fragments to the posterior extradural space is rare, and migration free causing cauda equina syndrome exceptionally rare. Methods. Three patients with posteriorly migrated epidural were evaluated radiograph, computed tomography, magnetic resonance imaging underwent surgery. Results. All responded well operative therapy complete relief...

Objective To characterize the importance of vertical angle sacral curvature (VASC) in lumbar disc herniations. Methods Morphological data derived from sagittal MRI imaging. The statistical significance findings are discussed. angles 60 female patients with herniations (LDH) were compared 34 without LDH. Results 128 185 met our inclusion criteria. is statistically significantly bigger females when to subjects control group, 28.32 and 25.4, respectively. (p=0.034<0.05). Same difference was not...

There is no study in the literature that investigates an asymmetric morphological feature of frontal sinus (FS).Four hundred and sixty-nine consecutive direct X-rays FSs were analyzed for asymmetry between right left sides. When height contour FS existed, this difference was quantified.Of 469 patients, 402 patients (85.7%), there sides FS. Of these 235 (50.1%) dominant on side, whereas 167 (35.6%) right, sinuses remaining 67 (14.3%) symmetric.The comparisons parameters performed using...

Lumbar disc herniations have been extensively studied in the literature. Asymmetric trunk muscle anatomy could affect development of this entity which has never quantitatively previously. The purpose manuscript was to analyze operated sides herniated lumbar disc.Data files patients with herniation author's hospital between January 2007 and March 2009 were analyzed.In side analysis, discectomy 53% on left side, 40% right difference two statistically significant.The asymmetric distribution may...

Hydrocephalus in its various forms constitutes one of the major problems pediatric neurosurgical practice. The placement a ventriculoperitoneal (VP) shunt is most common form treatment for hydrocephalus, so that all neurosurgeons struggle with malfunctions and their complications. Well-known complications are connected use valve systems (malfunction, infectious, overdrainage, secondary craniosynostosis, etc.). We report an unusual case protruding abdominal catheter from urethra. This girl...

Disc fragments are well known to migrate superior, inferior, or lateral sites in the anterior epidural space, posterior migrated lumbar disc is an extremely rare disorder, 61 cases have been reported date. However, there were no with perforated ligamentum flavum (LF). We report a different case perforation of by fragment. To best our knowledge, this first LF sequester disc.
