(2015) Akman, Tarık; Şen, Halil Murat; Coşar, Murat; Güven, Mustafa; Aras, Adem Bozkurt
Medulloblastom en sık görülen malign ve kontrol edilemeyen çocukluk çağı beyin tümörüdür. Tümör her yaştaki hastalardagörülür, 3 ve 9 yaş arasındaki çocuklarda bir zirveye ulaşır ve aynı zamanda çocukluk çağında en sık görülen kötü huylubeyincik tümörüdür. Yetişkinlerde beyin tümörlerinin %1 ile %2 sini oluşturur. Tanım olarak, medulloblastomlar genellikleposterior fossa, bazen pineal bölge veya pontoserebellar bölgeden kaynaklanan tümörler histolojik olarak benzer şekildesınıflandırılır. Bu hastalığın geleneksel tedavisi, posterior fossa cerrahisi, ardından posterior fossaya yüksek doz olmakkaydıyla kraniyospinal radyasyon tedavisi şeklindedir. Bu yazıda, 13 yaşında bir kız çocuğunda baş ağrısı ve baş dönmesibelirtileri ile ortaya çıkan, astrositomu taklit eden bir posterior fossa medülloblastomu olgusunu sunuyoruz.

(Turkish Neurosurgical Soc, 2014) Aras, Adem Bozkurt; Ozkan, Omer Faruk; Alar, Timucin; Ozkan, Adile; Arik, M. Kasim; Kosar, Sule; Kirilmaz, Bahadir
Vascular complications after lumbar discectomy are rarely seen. We present a unique and potentially life-threatening postoperative complication from this procedure. A 27-year-old man was admitted to our emergency vascular unit 1 day after a lumbar discectomy, during which a scalpel blade fragmented and a part was lost. Radiological images of the patient were performed and a broken scalpel blade was located anterior to the sacrum. An anterior laparotomy was performed which identified a mass within the left iliac vein that migrated suddenly to the inferior vena cava. An emergency angiography was performed, by which time the scalpel blade had ascended to the right-sided inferior pulmonary artery. It was subsequently removed via a right lateral thoracotomy.

(Çanakkale Onsekiz Mart Üniversitesi, 2014) Akman, Tarık; Aras, Adem Bozkurt; Güven, Mustafa; Alkan, Bahadır; Kiraz, Hasan Ali; Koşar, Şule; Şen, Halil Murat; Coşar, Murat
Dünya sağlık örgütü (WHO) kaynaklarına göre kanser, kardiyovasküler hastalıklar sonrası en sık görülen ölüm sebebidir. Tüm kanser olguları açısından karşılaştırıldığında akciğer kanseri görülme sıklığı açısından kadın cinsiyette ikinci sırada, erkek cinsiyette ise birinci sıradadır. Akciğer kanseri olgularının en sık görülen tipi ise küçük (yulaf) hücreli tipi olup, primeri açısından kıyaslandığında ise skuamöz hücreli varyantıdır. Akciğer kanserli olguların ilk konulan tanısında % 10-14’ unda kranial metastaz görülmektedir. Metastatik lezyon açısından mukayese edildiğinde ise kranial metastazlar küçük hücreli akciğer kanserinde görülmektedir. İntrakranial olgularda % 80-85’ inde supratentoriyel yerleşim görülür. Skuamöz hücreli akciğer kanserinin davranış şekli olarak sıklıkla geç metastaz yapmakta, kranial metastazı ise nadir olarak görülmektedir.İntrakranial metastaza bağlı görülebilecek semptomlar zamam zaman bulantı, kusmanın eşlik edebildiği başağrısı, fokal nörolojik bulgular, epileptik nöbetler, serebellar fonksiyonlarda bozulmadır. Beyin metastazlarının geliştiği akciğer tümörleri radyolojik olarak genellikle apikal ve periferik yerleşimlidir.Akciğer kanserinin kranial metastazı sıklıkla semptomatik hastalarda, daha nadir olarak da tarama amaçlı çekilen diagnostik kranial BT, beyin MRG, PET- CT sırasında saptanmaktadır.Bu çalışmamızda akciğer skuamöz hücreli kanser tanısıyla takip edilen hastada, intrakranial frontal ve temporal bölgede multipl metastazları saptanan olgunun literatür eşliğinde tartışılması amaçlanmıştır.

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.

(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.
Correction to: The Neuroprotective Effect of Coumaric Acid on Spinal Cord Ischemia/Reperfusion Injury in Rats (Inflammation, (2015), 38, 5, (1986-1995), 10.1007/s10753-015-0179-0)
(Springer, 2025) Guven, Mustafa; Sehitoglu, Muserref Hilal; Yuksel, Yasemin; Tokmak, Mehmet; Aras, Adem Bozkurt; Akman, Tarik; Golge, Umut Hatay
The authors have noticed that there is a mistake in the material method of the article. While writing the surgical procedure of the ischemia, the time was mistakenly written as 20 minutes in 2, 3 and 4 groups, in the Material and Method section. The correct period of time should be 45 minutes in 2, 3 and 4 groups in the article. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

(Turkish Neurosurgical Soc, 2016) Guven, Mustafa; Ceylan, Davut; Aras, Adem Bozkurt; Akbal, Ayla; Gokmen, Ferhat; Resorlu, Hatice; Alkan, Bahadir
AIM: The objective of this study was to investigate the effect of using 2 different surgical techniques (curette or high-speed drill) in anterior cervical discectomy surgery on the healing of cases. MATERIAL and METHODS: Fifty-four operated cervical disc hernia cases were retrospectively examined in 2 groups. Discectomy and osteophytectomy were carried out in Group A by using a high-speed drill, while a curette was used for group B. Preoperative and postoperative computerized tomography and direct radiography were performed. Cervical disc height, cervical and segmental lordotic angles were calculated. The visual analogue scale and Odom's criteria were used in the assessment of pain and clinical healing. The fusion ratio of both groups was compared. The Mann-Whitney U test was used to compare data from the groups. RESULTS: Satisfactory results were obtained in the groups where high-speed drill and curette were used. Independently from the surgical technique, pain scores were significantly reduced in both groups after surgery. No radiologically significant differences were identified between the two groups within the postoperative period. CONCLUSION: Either high-speed drill or curette can be chosen for the osteophytectomy and discectomy stages of anterior cervical discectomy operations.

(Taylor & Francis Inc, 2016) Yuksel, Yasemin; Guven, Mustafa; Kaymaz, Burak; Sehitoglu, Muserref Hilal; Aras, Adem Bozkurt; Akman, Tarik; Tosun, Murat
Aim: The purpose of this study was to evaluate the possible protective/therapeutic effects of aloe vera (AV) on ischemia-reperfusion injury (I/R) of spinal cord in rats. Materials and Methods: A total of 28 Wistar Albino rats were divided into four random groups of equal number (n = 7). Group I (control) had no medication or surgery; Group II underwent spinal cord ischemia and was given no medication; Group III was administered AV by gastric gavage for 30days as pre-treatment; Group IV was administered single dose intraperitoneal methylprednisolone (MP) after the ischemia. Nuclear respiratory factor-1 (NRF1), malondialdehyde (MDA) and superoxide dismutase (SOD) levels were evaluated. Tissue samples were examined histopathologically and neuronal nitric oxide synthase (nNOS) and nuclear factor-kappa B (NF-B) protein expressions were assessed by immunohistochemical staining. Results: NRF1 and SOD levels of ischemia group were found to be lower compared to the other groups. MDA levels significantly increased after I/R. Treatment with AV and MP resulted in reduced MDA levels and also alleviated hemorrhage, edema, inflammatory cell migration and neurons were partially protected from ischemic injury. When AV treatment was compared with MP, there was no statistical difference between them in terms of reduction of neuronal damage. I/R injury increased NF-B and nNOS expressions. AV and MP treatments decreased NF-B and nNOS expressions.Conclusions: It was observed that aloe vera attenuated neuronal damage histopathologically and biochemically as pretreatment. Further studies may provide more evidence to determine the additional role of aloe vera in spinal cord ischemia reperfusion injury.

(Springer/Plenum Publishers, 2015) Sen, Halil Murat; Ozkan, Adile; Guven, Mustafa; Akman, Tarik; Aras, Adem Bozkurt; Sehitoglu, Ibrahim; Alacam, Hasan
Many studies of brain ischemia have shown the role played by massive ischemia-induced production of reactive oxygen species, the main mechanism of neuronal death. However, currently, there is no treatment choice to prevent cell death triggered by reactive oxygen species. In our study, we researched the effects of tannic acid, an antioxidant, on the ischemic tissue of rats with induced middle cerebral artery occlusion. The animals were divided into three groups of eight animals. The sham group were only administered 10 % ethanol intraperitoneally, the second group had middle cerebral artery occlusion induced and were given 10 % ethanol intraperitoneally, while the third group had middle cerebral artery occlusion with 10 mg/kg dose tannic acid dissolved in 10 % ethanol administered within half an hour intraperitoneally. The rats were sacrificed 24 h later, and brain tissue was examined biochemically and histopathologically. Biochemical evaluation of brain tissue found that comparing the ischemic group with no treatment with the tannic acid-treated ischemia group; the superoxide dismutase (SOD) levels were higher, malondialdehyde (MDA) levels were lower, and nuclear respiratory factor-1 (NRF-1) was higher in the tannic acid-treated group. Histopathological examination showed that the histopathological results of the tannic acid group were better than the group not given tannic acid. Biochemical and histopathological results showed that tannic acid administration had an antioxidant effect on the negative effects of ischemia in brain tissue.

(Çanakkale Onsekiz Mart Üniversitesi, 2014) Ganiüsmen, Ozan; Çiftçi, Engin; Aras, Adem Bozkurt; Güven, Mustafa; Çıtak, Güven; Korkmaz, Hakan
This study investigated symptoms, physical examination findings and cervical roentgenograms of patients who were surgically treated for single level cervical disc disease. The purpose of our study is to compare and present radiological and clinical findings in preoperative and postoperative groups. Anterior cervical microdiscectomy and fusion with using peek cage was applied to patients. Verbal definition scale was used for clinical evaluation of 44 patients that were operated at Tepecik Education and Research Hospital between September 2008 to September 2009. Pretreatment and post treatment data were compared. According to verbal definition scale, 19 patients had unbearable pain, 23 patients had severe pain, 1 patient had moderate pain before surgery. After the operation, 1 patient had moderate, 1 patient had mild pain. There was no significant difference between preoperative and postoperative lordosis angles and neighbor lower disc height. However comparison of pretreatment and post treatment disc height, neighbor upper disc height and segment angles revealed statistically significant difference. Anterior cervical discectomy and fusion with peek cage is withstanding treatment method for cervical disc disease. This procedure provides both clinical and radiological improvement.

(Turkish Neurosurgical Soc, 2016) Aras, Adem Bozkurt; Guven, Mustafa; Balak, Naci; Ayan, Erdogan; Uyar, Suheyla Bozkurt; Elmaci, Ilhan
AIM: The intervertebral disc starts to degenerate when a human being begins to stand and learn to walk. It is known that many extrinsic, intrinsic and genetic factors play a role in disc degeneration. In this study, we examined whether the matrix metalloproteinase 11 might be associated with intervertebral disc degeneration. MATERIAL and METHODS: Fifty-six patients with lumbar disc herniations who were operated at Gortepe Education and Research Hospital, Neurosurgery Clinic between September 2008 and December 2009 were prospectively reviewed. History and complaints were obtained from the case reports. Neuroradiological evaluation was performed with magnetic resonance imaging. Surgical findings of cases were reported in the operation notes. Microscopic posterior hemipartial laminectomy and discectomy were performed in all cases. Degenerated herniated disc material of all cases extracted during surgery was evaluated with immunohistochemical staining in Marmara University, Institute of Neurological Sciences, Pathology Laboratory. RESULTS: Comparing the immunohistochemical staining of cases who were 50 years or younger and cases who were over 50 years old, statistical significance was determined. CONCLUSION: Matrix metalloproteinase 11 has a role in degenerating intervertebral disc disease, but it is not the only factor. Matrix metalloproteinase 11 might be a genetic factor in young-middle aged patients.

(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.

(2020) Malçok, Ümit Ali; Şafak, Özbey; Akman, Tarık; Aras, Adem Bozkurt
Maç:Omurga fraktürlerinin tedavisinde hedef anatomik redük-siyon sağlamak, spinal deformiteyi önlemek, ağrıyı azaltmak, ver-tebra yüksekliğini yeniden oluşturmak ve erken mobilizasyon ile hastanın günlük aktivitelerine erken geri dönmesini sağlamaktır. Bu çalışma ile osteoporoz veya tümöre bağlı olarak vertebra korpus fraktürü gelişmiş hastalara uygulanan perkütan vertebroplasti (PVP) veya perkütan balon kifoplasti (PBKP) sonrası ortaya çıkan klinik ve radyolojik sonuçları operasyon öncesi ve sonrası değerlendirmeyi amaçladık.Materyal ve Metot:Tek seviye vertebra korpus fraktürü olan 65 olguya, (44’u kadın %67,7, 21’i erkek %32,3), PVP ve PBKP işlemi uygulandı. Vakalar radyolojik olarak Magnetik Rezonans Görüntüleme, Bilgisayarlı Tomografi ve X-ray radyografi ile operasyon öncesi ve sonrası olarak değerlendirildi. Radyolojik değerlendirmede vertebra yükseklikleri ve Cobb açıları ölçüldü. Ağrıdaki değişimlerin izlenmesinde Visual Analog Skala (VAS) kullanıldı.Bulgular:Vakaların başlıca semptomu “ağrı” olup, PVP ve PBKP ile ortalama VAS skorları 7,9’dan 2’ye geriledi (p<0,05). Vertebra korpus açısındaki ortalama düzelme 2,2 derece olarak ölçüldü. Ön, orta ve arka vertebra korpus yüksekliklerinde anlamlı derecede artış olduğu görüldü (p=0,0001).Sonuç:Osteoporoz ve tümöre bağlı gelişen vertebra korpus frak-türlerinde uygulanan PVP veya PBKP operasyonu ağrının azaltıl-masında, vertebra korpus yüksekliğinin arttırılmasında ve Cobb açı düzeltilmesinde güvenilir ve etkili bir tedavi şeklidir. Verilen PMMA miktarının arttırılması; VAS değerinin azalmasına, Cobb açısının düzelmesine ve vertebra korpus yüksekliğinin artışına anlamlı katkı sağlamadı.

(Turkish Neurosurgical Soc, 2015) Cosar, Murat; Ozer, A. Fahir; Alkan, Bahadir; Guven, Mustafa; Akman, Tarik; Aras, Adem Bozkurt; Ceylan, Davut
AIM: Anterior transodontoid screw fixation technique is generally chosen for the management of type II odontoid fractures. The nonunion of type II odontoid fractures is still a major problem especially in elderly and osteoporotic patients. Eleven osteoporotic type II odontoid fracured patients were presented in this article. MATERIAL and METHODS: We have divided 11 patients in two groups as classical and Ozer's technique.We have also compared (radiologically and clinically) the classical anterior transodontoid screw fixation (group II: 6 cases) and Ozer's transodontoid screw fixation technique (group I: 5 cases) retrospectively. RESULTS: There was no difference regaring the clinical features of the groups. However, the radiological results showed 100% fusion for Ozer's screw fixation technique and 83% fusion for the classical screw fixation technique. CONCLUSION; In conclusion, we suggest that Ozer's technique may help to increase the fusion capacity for osteoporotic type II odontoid fractures.
