Surgical treatment is usually suggested to patients with severe symptoms. In this study, we aimed to examine the effect of the dominant hand on the clinical results of CTS decompression surgery. Methods: Fifty (5M, 45F) patients were included in the study. The Edinburgh Handedness Inventory was used to identify the dominant hand of patients included in the study. Visual analogue scale (VAS) values were evaluated pre- and postoperatively. Results: Twenty-eight patients underwent surgery on the dominant hand and 22 patients had surgery to their non-dominant hand. The VAS values of patients who underwent non-dominant hand surgery were lower than those who underwent surgery on the dominant hand. Conclusion: In our study, it was determined that patient complacency after surgical procedures performed on dominant hands was less when compared with the non-dominant side. We believe that suitable exercise and protection programs for dominant hands in the postoperative period of carpal tunnel surgery, in addition to a good and careful surgical technique, positively affects the results of surgical treatment.Item Efficacy of Endovascular Treatment and Feasibility of Stent-Assisted Coiling in the Presence of Severe and Symptomatic Vasospasm(2017) Andic, Cagatay; Kardes, Ozgur; Durdag, Emre; Gedikoglu, Murat; Akin, Sule; 0000-0001-8581-8685; 0000-0003-2854-941X; 0000-0001-6939-5491; 0000-0001-6423-1076; 27811177; AAM-3180-2021; P-5895-2018; AAK-1734-2021; AAJ-2094-2021Background and purpose In patients with aneurysmal subarachnoid hemorrhage, deciding the optimal treatment strategy is challenging in the presence of severe and symptomatic vasospasm and the existing literature is limited. The purpose of this study was to evaluate the safety and effectiveness of endovascular treatment of intracranial aneurysms and the feasibility of stent-assisted coiling during severe and symptomatic vasospasm. Materials and methods Fifteen consecutive patients with 18 aneurysms who underwent endovascular treatment during severe and symptomatic vasospasm were included in the study. Patient and aneurysm characteristics, treatment technique, and clinical and angiographic outcomes were retrospectively evaluated. Results Aneurysms were treated by the following techniques: single catheter coiling in 9, stent-assisted coiling in 8 (3 aneurysms with Y-configuration double stents), and balloon-assisted coiling in 1. All patients showed angiographic improvement of vasospasm after treatment including a noticeable dilation of the spastic parent arteries following deployment of the stents. According to the immediate post-treatment angiography results, 14 aneurysms (77.8%) had class I occlusion and 4 (22.2%) had class II occlusion. Three patients died during the course of subarachnoid hemorrhage. Mortality was related to the poor grade (Hunt and Hess grade V) and cardiovascular complications in two and refractory vasospasm one patient. The remaining patients had favorable clinical outcomes at follow-up (modified Rankin Scale 0-2). Conclusions Endovascular treatment of intracranial aneurysms during severe and symptomatic vasospasm is safe and effective. Stent-assisted coiling in the presence of severe vasospasm is also feasible in wide-necked aneurysms with the additional benefits of mechanical vasodilation.Item Brain Metastasis of Penile Angiosarcoma(2018) Kardes, Ozgur; Aydemir, Fatih; Suner, Halil Ibrahim; Durdag, Emre; Civi, Soner; Tufan, Kadir; Kayaselcuk, Fazilet; https://orcid.org/0000-0003-2854-941X; https://orcid.org/0000-0002-5957-8611; https://orcid.org/0000-0001-6939-5491; https://orcid.org/0000-0002-1055-5152; https://orcid.org/0000-0003-1509-4575; https://orcid.org/0000-0002-1180-3840; 29150829; P-5895-2018; AAJ-5381-2021; AAK-1734-2021; U-2400-2018; AAK-1686-2021; AAE-2550-2021Angiosarcoma is a rare malignancy originating from vascular endothelial cells. Brain metastasis of aniosarcomas are uncommon up to the literature. Penile angiosarcomas are also seldom among all anjiosarcomas. A case with penile angiosarcoma with confirmed brain metastasis is aimed to be reported and contribute to the literature for similar cases.Item The Effects of Infusion of Perineural Pregabalin in the Experimentally Created Sciatic Nerve Anastomosis in Rats(2018) Civi, Soner; Bulduk, Erkut Baha; Kocer, Nazim Emrah; Kardes, Ozgur; Suner, Halil Ibrahim; Durdag, Emre; Tufan, Kadir; 0000-0002-5943-9283; 0000-0003-2854-941X; 0000-0002-5957-8611; 0000-0001-6939-5491; 0000-0003-1509-4575; 30569903; AAM-5436-2021; P-5895-2018; AAJ-5381-2021; AAK-1734-2021; AAK-1686-2021INTRODUCTION AND OBJECT: The aim of our study was to assess the effect of perineural pregabalin administration on the success of coaptation in experimental rat sciatic nerve anastomosis by measuring the expression of anti-inflammatory cytokine TGF-beta. It is thus to provide alternative solutions to this problem which we often see in clinical practice and whose results are not satisfactory. METHODS: In our study, 40 adult, male, Sprague-Dawley rats; 5 groups were randomly assigned Group 1: This group's sciatic nerves were dissected and the surgical site was sutured. Group 2: Rats whose sciatic nerves are sectioned transversely through the fill-thickness and end-to-end anastomosis is performed and no additional procedure is performed. Group 3: Intraperitoneal administration of 30 mg / kg pregabalin for 7 days with anastomosis. Group 4: 30 mg/kg pregabalin given orally for 7 days with anastomosis. Group 5: Given 10 microliters / h pregabalin subcutaneous perineural infusion for 7 days with anastomosis. After 60 days of surgery, the experiment was terminated with high dose thiopental (50 mg/kg). The right sciatic nerves of all animals were taken and sections obtained were examined immunohistopathologically. RESULTS: Inflammation was significantly less in the 5th group than in the other groups. TGF-beta expression in Groups 3, 4, and 5 is significantly higher than Groups 1 and 2, which also supports this situation. Although the expression in group 5 was not statistically significant, the number of TGF-beta expression was higher than Groups 3 and 4. In terms of immunohistochemical properties; 1 to 3, 1 to 4, 1 to 5, 2 to 5 groups were statistically significant (p<0,05). CONCLUSIONS: In conclusion, perinural infusion of pregabalin into the anastomotic region has not been previously tried in the literature and it has been found that immunohistochemistry provides positive contributions to healing of anastomosis. More research is needed to demonstrate that this effect is superior to other methods of administration of the drug.Item Malignant Congenital Orbital Teratoma: Glioblastoma Multiforme With Primitive Neuronal Pattern And Choroid Plexus Papilloma: A Rare Diagnosis At An Unusual Age(2022) Hasbay, Bermal; Kayaselcuk, Fazilet; Kardes, Ozgur; 35435383Childhood orbital teratomas are usually congenital lesions that are most often present at birth with progressive, massive unilateral proptosis. During the routine controls of 27-year-old woman between 26-27th weeks of pregnancy her fetal ultrasonography (USG) revealed a mass in the eye of the fetus, and termination was recommended. The family refused the termination option and in the 37th week of pregnancy, vaginal delivery is performed in an external medical center. The mass in the baby's eye was surgically removed. Microscopic examination revealed disorganized ocular tissues, adipose tissue, microcalcification, nerve plexuses as well as areas of neuronal nodules including hypercellular areas, palisatic necrosis, and microvascular proliferation. The immunprofile- patchy GFAP staining in the areas of cellular epithelioid and spindled cells that also show an focal and sparse expression p53 staining and a high proliferation rate in Ki67 staining-confirmed the hematoxylin-eosin (HE) impression of a teratoma with a component of glioblastoma (GBM). In this unique presentation of a malignant orbital teratoma with a GBM, we have identified three tumor components: (1) GBM component, (2) nodules of neuroglial tissue with mature neurons and BRAF mutation, and (3) papillary proliferation possibly representing a choroid plexus papilloma.
