    (Turkish Neurosurgical Soc, 2010) Eser, Betul; Cosar, Murat; Eser, Olcay; Erdogan, Mujgan O.; Aslan, Adem; Yildiz, Handan; Boyaci, Gazi
    AIM: This study aimed to investigate the 677C>T and 1298A>C MTHFR gene polymorphisms and their metabolic effects on the levels of folate, vitamin B12 and homocysteine in the serum of Turkish spina bifida occulta (SBO) patients and healthy individuals in disease. MATERIAL and METHODS: A case-control study was performed to detect 677C>T and 1298A>C MTHFR gene polymorphisms in 39 SBO patients and 34 healthy individuals. The folate, vitamin B12 and homocysteine concentrations in the serum of SBO and healthy individuals were evaluated and compared with MTHFR gene polymorphisms. RESULTS: 677 CC/CT/TT MTHFR genotype frequency differences between the SBO patients and controls were not significant (x(2)=3.325, P=0.068; x(2)=1.479, P=0.224; x(2)=0.275, P=0.600; respectively). 1298A>C MTHFR genotype frequency differences between the SBO patients and controls were significant (x(2)=8.477, P=0.004). The frequencies of the A and C alleles of the 1298A>C polymorphism did not differ in a statistically significant manner between the groups (x(2)=0.576, P=0.448). The biochemical parameters were not significantly different between SBO patients and healthy individuals (P>0.05). CONCLUSION: The 677C>T and 1298A>C polymorphisms of the MTHFR gene cannot be regarded as major risk factors for SBO in the Turkish patients 677TT homozygosity may affect the metabolism of homocysteine.

    A Case of Posterior Mediastinal Ganglioneuroma: The Importance of Preoperative Multiplanar Radiological Imaging
    (Galenos Publ House, 2013) Kizildag, Betul; Alar, Timucin; Karatag, Ozan; Kosar, Sule; Akman, Tarik; Cosar, Murat
    Ganglioneuromas are mostly seen in adolescents and young adults and they are neurogenic tumors originating from sympathetic ganglions with a benign histology. Although ganglioneuromas are benign, the treatment is surgical as they can cause pain or compression symptoms, can be locally aggressive and can lead to cord compression. We present a young adult female with a ganglioneuroma of the right posterior mediastinum who presented with lower back pain, together with the clinical features, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings, differential diagnosis tips and their contribution to surgical planning.

    A Comparison of the Degree of Lateral Recess and Foraminal Enlargement With Facet Preservation in the Treatment of Lumbar Stenosis With Standard Surgical Tools Versus a Novel Powered Filing Instrument: A Cadaver Study
    (2007) Cosar, Murat; Khoo, Larry T.; Yeung, Christopher A.; Yeung, Anthony T.
    Background: The SurgiFile (SurgiFile, Inc., Carlsbad, California) is a specialized tool designed for the treatment of lateral recess and foraminal stenosis that allows surgeons to internally expand and decompress the entire length of the neural foramen while preserving the integrity of the overlying facet complex. Methods: We used two cadaveric specimens in this study. After they removed the lamina and spinous processes of L2, L3, L4, and L5 from the dorsal spine, fellowship-trained spinal surgeons used the standard tools and the SurgiFile to the best of their experience and ability on alternating sides of each level to decompress the lateral recess and neural foramen while still preserving at least 50% of the dorsal facet complex. Using preoperative and postoperative fine-cut CT scans with axial and sagittal reconstructions, we evaluated the degree of decompression and the amount of preserved facet complex using analytical tests and recording the measurements. Results: The difference between the proximal recess and lateral foramen of the groups was statistically significant in the axial CT images. On sagittal reconstruction CT images, the difference between the two groups was significant (P < 0.05, Wilcoxon) only for the lateral foramen. Although a strong trend toward better area change was evident for the proximal recess measurements in the experimental tool sides, this did not achieve statistical significance. Macroscopic and CT scans measurements showed that the amount of facetectomy for adequate decompression with the SurgiFile was less than the amount achieved with the standard tools. Conclusions: For the treatment of spinal stenosis, this novel powered-file instrument provides surgeons with a new means of decompressing the lateral recess and neural foramina. In this cadaveric study, procedures performed with the SurgiFile tool showed a statistically superior degree of decompression as compared with the standard surgical instruments and techniques. © 2007 The Spine Arthroplasy Society.

    (Pergamon-Elsevier Science Ltd, 2010) Hatiboglu, Mustafa Aziz; Altunkaynak, Abdusselam; Ozger, Mehmet; Iplikdoglu, Ahmet Celal; Cosar, Murat; Turgut, Namigar
    We aimed to investigate if the outcome of the patients with intracranial aneurysm could be predicted by fuzzy logic approach. Two hundred and forty two patients with the diagnosis of intracranial aneurysm were assessed retrospectively between January, 2001 and December 2005 We recorded World Federation of Neurological Surgeons Scale (WFNSS), Fisher Scale and age at admission and Glasgow Outcome Score (GOS) at discharge from hospitalization for all the patients We developed fuzzy sets by dividing WFNSS into four groups as good, fair, bad and very bad; age into three groups as young, middle and old, Fisher scale into three groups as few. moderate and large; outcome score Into four groups as bad, fair, good and very good. We calculated the Outcome of the patient with these sets by fuzzy model. Predicted Outcome by fuzzy logic approach correlated with observed outcome scores of the patients (p > 0.05), including 95% confidence interval. We showed that outcome of the patients with aneurysm can be predicted by fuzzy logic approach, accurately (C) 2009 Elsevier Ltd. All rights reserved

    Anterior Approach to Disc Herniation With Modified Anterior Microforaminotomy at C7-T2 Technical Note
    (Lippincott Williams & Wilkins, 2009) Ozer, Ali Fahir; Kaner, Tuncay; Sasani, Mehdi; Oktenoglu, Tunc; Cosar, Murat
    Study Design. An easy surgical method to reach C7-Th and T1-T2 foraminal disc herniation is described. Objective. To describe a surgical technique that involves an anterior approach to disc herniation with inverted cone-shaped partial minicorpectomy. Summary of Background Data. Anterior approaches to the cervicothoracic junction are difficult in spinal surgery because the operative area is narrow. The manubrium, the clavicles, and the slope of the vertebral bodies obstruct the view of the surgeon. The vascular and neural structures of the superior mediastinum limit the surgical approach. The thoracic duct and recurrent laryngeal nerve present risks for injury, especially with approaches from the right side. Disc herniations at the C7-T2 level are very rare. Posterior approaches at these levels are advocated because radicular symptoms occur more often than myelopathic symptoms, but anterior discectomy and fusion are generally preferred by many spinal surgeons, as these are approaches that are more intuitive. Methods. We review the case histories of all of our patients that underwent inverted cone-shaped partial minicorpectomy and fusion at the C7-T2 disc levels between 2000 and 2008. We applied the surgical techniques described in this manuscript. Results. The mean follow-up duration was 50 months postoperation. Physical examinations were performed and radiographs were taken at the end of the first 6 months postoperative and every 12 months thereafter. No meaningful changes were recorded on either the Visual Analog Scale or the Neck Disability Index. Cervical alignment was unchanged before and after surgery. Conclusion. Minicorpectomy technique of C7 or T1 vertebra is an easy and appropriate method for treating foraminal disc herniation between the C7-T1 and T1-T2 levels.

    Basilar artery angulation and vertigo due to the hemodynamic effect of dominant vertebral artery
    (Churchill Livingstone, 2008) Cosar, Murat; Yaman, Mehmet; Eser, Olcay; Songur, Ahmet; Ozen, Oguz A.
    Vertebral arteries form the basilar artery at the pontobulbar junction. The vertebral artery may have dominancy in one of them. The branches of basilar arteries supply blood for the vestibular nuclei and its connections. Vertigo is seen generally in the upper middle aged patients. Vertigo can be observed in dolichoectasia of basilar artery such as angulation and elongation, because of the diminished blood supply and changed hemodynamic factors of vestibular nuclei and its connections. We hypothesized that angulation or elongation of basilar artery can be estimated according to the unilateral vertebral artery dominant hypertensive patients. The basilar artery can angulate from the dominant side of vertebral artery to the recessive side. These angulation and elongation can effect the hemodynamic factors in absence of growing collateral arteries. So, the vertigo attacks may occur in these patients. (C) 2007 Elsevier Ltd.

    Changes in retinal nerve fiber layer thickness after spinal surgery in the prone position: a prospective study
    (Elsevier Science Inc, 2015) Gencer, Baran; Cosar, Murat; Tufan, Hasan Ali; Kara, Selcuk; Arikan, Sedat; Akman, Tarik; Kiraz, Hasan Ali
    Background and objectives: Changes in ocular perfusion play an important role in the pathogenesis of ischemic optic neuropathy. Ocular perfusion pressure is equal to mean arterial pressure minus intraocular pressure. The aim of this study was to evaluate the changes in the intraocular pressure and the retinal nerve fiber layer thickness in patients undergoing spinal surgery in the prone position. Methods: This prospective study included 30 patients undergoing spinal surgery. Retinal nerve fiber layer thickness were measured one day before and after the surgery by using optical coherence tomography. Intraocular pressure was measured by tonopen six times at different position and time-duration: supine position (baseline); 10 min after intubation (Supine 1); 10 (Prone 1), 60 (Prone 2), 120 (Prone 3) min after prone position; and just after postoperative supine position (Supine 2). Results: Our study involved 10 male and 20 female patients with the median age of 57 years. When postoperative retinal nerve fiber layer thickness measurements were compared with preoperative values, a statistically significant thinning was observed in inferior and nasal quadrants (p=0.009 and p=0.003, respectively). We observed a statistically significant intraocular pressure decrease in Supine 1 and an increase in both Prone 2 and Prone 3 when compared to the baseline. Mean arterial pressure and ocular perfusion pressure were found to be significantly lower in Prone 1, Prone 2 and Prone 3, when compared with the baseline. Conclusions: Our study has shown increase in intraocular pressure during spinal surgery in prone position. A statistically significant retinal nerve fiber layer thickness thinning was seen in inferior and nasal quadrants one day after the spinal surgery. (C) 2014 Sociedade Brasileira de Anestesiologia.

    Chronic Spinal Epidural Hematoma in an Adult
    (Modestum Ltd, 2015) Tokmak, Mehmet; Aras, Adem Bozkurt; Altiok, Inci Baltepe; Guven, Mustafa; Cosar, Murat
    Spinal epidural hematoma (SEH) causing neurological deficit is a rare clinical entity. It may have either traumatic origin or it may occur spontaneously. Majority of the reported cases of SEH had nontraumatic causes and most of them were in the acute stage. Early chronic traumatic SEH in an adult is very rare and its prompt diagnosis with magnetic resonance imaging (MRI) is crucial for the accurate management of the patient. Our case was 56 year-old man presented at our neurosurgery clinic with a complaint of progressive burning pain, weakness, paresthesia over the left leg and hypoesthesia over the pelvic region. In this report, we presented a postraumatic lumbar SEH which is a unique presentation of chronic traumatic SEH because of long time interval between the trauma and beginning of the symptoms.

    Clinical outcomes after posterior dynamic transpedicular stabilization with limited lumbar discectomy: Carragee classification system for lumbar disc herniations
    (2010) Kaner, Tuncay; Sasani, Mehdi; Oktenoglu, Tunc; Cosar, Murat; Ozer, A.F.
    Background: The observed rate of recurrent disc herniation after limited posterior lumbar discectomy is highest in patients with posterior wide annular defects, according to the Carragee classification of type II (fragment-defect) disc hernia. Although the recurrent herniation rate is lower in both type III (fragment-contained) and type IV (no fragment-contained) patients, recurrent persistent sciatica is observed in both groups. A higher rate of recurrent disc herniation and sciatica was observed in all 3 groups in comparison to patients with type I (fragment-fissure) disc hernia. Methods: In total, 40 single-level lumbar disc herniation cases were treated with limited posterior lumbar microdiscectomy and posterior dynamic stabilization. The mean follow-up period was 32.75 months. Cases were selected after preoperative magnetic resonance imaging and intraoperative observation. We used the Carragee classification system in this study and excluded Carragee type I (fragment-fissure) disc herniations. Clinical results were evaluated with visual analog scale scores and Oswestry scores. Patients' reherniation rates and clinical results were evaluated and recorded at 3, 12, and 24 months postoperatively. Results: The most common herniation type in our study was type III (fragment-contained), with 45% frequency. The frequency of fragment-defects was 25%, and the frequency of no fragment-contained defects was 30%. The perioperative complications observed were as follows: 1 patient had bladder retention that required catheterization, 1 patient had a superficial wound infection, and 1 patient had a malpositioned transpedicular screw. The malpositioned screw was corrected with a second operation, performed 1 month after the first. Recurrent disc herniation was not observed during the follow-up period. Conclusions: We observed that performing discectomy with posterior dynamic stabilization decreased the risk of recurrent disc herniations in Carragee type II, III, and IV groups, which had increased reherniation and persistent/continuous sciatica after limited lumbar microdiscectomy. Moreover, after 2 years' follow-up, we obtained improved clinical results. © 2010 Elsevier Inc.

    (Turkish Neurosurgical Soc, 2016) Guven, Mustafa; Cosar, Murat; Alkan, Bahadir; Aras, Adem Bozkurt; Akman, Tarik; Safak, Ozbey; Karaarslan, Oznur
    AIM: The aim of this study is to compare the different types of fusion materials known as PEEK cages used during anterior cervical discectomy (ACD) surgery. MATERIAL and METHODS: A total of 67 patients were operated and evaluated retrospectively under two groups (group A: 35 PEEK cage patients, group B: 32 bladed PEEK cage patients) between 2009 and 2013. Preoperative and postoperative (postoperative first day, postoperative 1st, 3rd and 12-24th mo) images were obtained. The cervical disc heights, cervical and segmental lordotic angles of the operated levels were calculated. Pain assessment was performed and fusion rates were also compared. Mann-Whitney U test was applied to compare the outcomes. RESULTS: The pain scores (especially for arm pain) were decreased significantly in both groups after surgery regardless of the type of operation technique (P<0.05). There were no significant differences between both groups at the disc height measurements of operated levels in postoperative periods (P>0.05). In addition to these; there was no significant difference between both groups of segmental and cervical lordodic angles in postoperative periods (P>0.05). There was no statistically significant difference between the fusion rates and pain scores of both groups (P>0.05). CONCLUSION: The PEEK cage and bladed PEEK cages can be used safely to obtain fusion after ACD.

    Condensing osteitis of the clavicle in a man: Any relationship with tooth decay?
    (Pakistan Medical Assoc, 2014) Altiok, Inci Baltepe; Tokmak, Mehmet; Akman, Tarik; Alkan, Bahadir; Cosar, Murat
    Condensing osteitis of the clavicle is a rarely seen pathology since its first description in 1974. Although mechanical stress is claimed for aetiology, but remains a dilemma for physicians. The intermittent or steady pain is variable in intensity and generally localised at the medial end of the involved clavicle, supraclavicular fossa, ipsilateral anterior thorax and shoulder. In this report, we present a 28-year-old man with the regression of the condensing osteitis of the clavicle after the extraction of a decayed tooth.

    Determining the Morphometry and Variations of the Confluens Sinuum and Related Structures Via a Silicone Painting Technique on Autopsy Patients
    (Lippincott Williams & Wilkins, 2014) Cosar, Murat; Seker, Askin; Ceylan, Davut; Tatarli, Necati; Sahin, Fevzi; Tokmak, Mehmet; Songur, Ahmet
    In this study, we aimed to investigate the morphometric and morphologic structures of the confluens sinuum (CS) and related structures with a silicone painting technique. We studied 30 cadavers. Twelve of them were washed with alcohol and filled with a silicone painting technique via the vena jugularis interna, internal carotid artery, and vertebral artery. The other 18 were autopsied postmortem. The CS and related structures were dissected under microscope. Their anatomy was investigated, and variations were noted. The diameters of the sinus sagittalis superior (SSS), CS, occipital sinus (OS), sinus rectus (SR), and bilateral transverse sinus (TS), and the angle between SSS and SR were measured. The mean diameters were 11.7 mm for SSS, 22.3 mm for CS, 5.25 mm for OS, 7.5 mm for SR, and 9.7 (right) and 9.1 mm (left) for TS. The angle between the SR and SSS was 58 degrees. There was no difference in the bilateral venous structures that drained to the SSS and TS. There was an extra drainage to the CS from the left side in 4 cases. The right TS was located superiorly in 7 cases compared with the left TS, and this process was correlated with the type of CS. A septum in the SSS was detected in 2 cases. In addition, we encountered an OS in 80% of the cases. We conclude that the septum inside the CS affects the dominancy of the TS, the angle between the SSS and SR, and the other venous variations.

    Does Glp-2 have a protective effect on cerebral ischemia/reperfusion model?
    (Tubitak Scientific & Technological Research Council Turkey, 2015) Topaloglu, Naci; Memi, Gulsun; Kaner, Tuncay; Deniz, Mustafa; Sahin, Onder; Guven, Mustafa; Cosar, Murat
    Background/aim: To investigate the neuroprotective effects of glucagon-like peptide 2 (Glp-2), which increases cerebral blood flow, on the hippocampal complex after cerebral ischemia/reperfusion (I/R) injury in rats. Materials and methods: Animals were randomized into 4 groups: sham, I/R + 0.9% NaCl, I/R + pre-Glp-2, and I/R + post-Glp-2. Cerebral ischemia was performed via the occlusion of the bilateral internal carotid artery for 40 min and continued with a reperfusion process. At the end of 6 h of reperfusion, animals were decapitated in all groups and brain tissues were removed. Malondialdehyde (MDA) and natural intracellular antioxidant glutathione (GSH) levels and myeloperoxidase (MPO) activities were measured in the left hippocampal tissue. The right hippocampal tissues of all group members were taken for histopathologic study. Results: MDA levels and MPO activities increased from Group I to Group II and decreased from Group II to Groups III and IV. On the other hand, GSH levels were not significantly different among the groups. The number of apoptotic hippocampal tissue cells increased from Group I to Group II and decreased from Group II to Groups III and IV. Conclusion: Our preliminary study revealed that Glp-2 treatment may decrease oxidative damage from I/R in cerebral tissue.

    Dural sinus filling defect: Intrasigmoid encephalocele
    (2013) Karatag, Ozan; Cosar, Murat; Kizildag, Betul; Sen, Halil Murat
    Filling defects of dural venous sinuses are considered to be a challenging problem especially in case of symptomatic patients. Many lesions have to be ruled out such as sinus thrombosis, arachnoid granulations and tumours. Encephalocele into dural sinus is also a rare cause of these filling defects of dural sinuses. Here, we report an extremely rare case with spontaneous occult invagination of temporal brain tissue into the left sigmoid sinus and accompanying cerebellar ectopia.

    Genistein Exerts Neuroprotective Effect on Focal Cerebral Ischemia Injury in Rats
    (Springer/Plenum Publishers, 2015) Aras, Adem Bozkurt; Guven, Mustafa; Akman, Tarik; Alacam, Hasan; Kalkan, Yildiray; Sılan, Coşkun; Cosar, Murat
    Brain ischemia and treatment are one of the important topics in neurological science. Free oxygen radicals and inflammation formed after ischemia are accepted as the most important causes of damage. Currently, there are studies on many chemopreventive agents to prevent cerebral ischemia damage. Our aim is to research the preventive effect of the active ingredient in genistein, previously unstudied, on oxidative damage in cerebral ischemia. Rats were randomly divided into three groups: control group (no medication or surgical procedure), ischemia group, and artery ischemia+genistein group, sacrificed at 24 h after ischemia. The harvested brain tissue from the right hemisphere was investigated histopathologically and for tissue biochemistry. Superoxide dismutase and nuclear respiratory factor 1 values decreased after ischemia and they increased after genistein treatment, while increased malondialdehyde levels after ischemia reduced after treatment. Apoptosis-related cysteine peptidase caspase-3 and caspase-9 values increased after ischemia, but reduced after treatment. Our study revealed that genistein treatment in cerebral ischemia reduced oxidative stress and neuronal degeneration. We believe that genistein treatment may be an alternative treatment method.

    Intracerebral hematoma complicated with brain abscess in an infant - Case report
    (Japan Neurosurgical Soc, 2008) Eser, Olcay; Cosar, Murat; Aslan, Adem; Koken, Resit; Aktepe, Fatma; Esert, Betul
    A 45-day-old infant presented with a rare case of intracerebral hematoma complicated with brain abscess which developed after vitamin K deficiency. He was admitted to our emergency department with complaints of fever and confusion. Physical, neurological, and laboratory examinations and cranial computed tomography identified vitamin K deficiency and intracerebral hematoma. He started to suffer convulsions. The patient underwent surgery. A brain abscess was discovered with an intracerebral hematoma. The intracerebral hematoma and abscess were evacuated and antibiotic therapy was initiated. Convulsions became rare and were controlled with midozalam administration. Follow-up computed tomography after 6 months showed encephalomalacic changes in the temporoparietal area. If feeding depends only on human milk, the amount of vitamin K prophylaxis given to neonates should be increased to support vitamin K related factors.

    (Springer, 2008) Cosar, Murat; Eser, Olcay; Aslan, Adem; Korkmaz, Serhat; Boyaci, Gazi; Aktepe, Fatma
    Introduction Intradiploic cavernous hemangioma of the skull is seen rarely. Intradiploic cavernous hemangiomas arise from the intrinsic vasculature of the bone and generally picks up at the fourth and fifth decades. Discussion and conclusion In this report, we present a 16-year-old child who was admitted with a swelling lesion in the right parietal bone and diagnosed as cavernous hemangioma after total extirpation.
