    Does The Dominant Hand Factor Have an Effect on Postoperative Recovery in The Surgical Treatment of Carpal Tunnel Syndrome?
    (2018) Civi, Soner; Tanburoglu, Anil; Suner, Halil Ibrahim; Kardes, Ozgur; Durdag, Emre; Tufan, Kadir; https://orcid.org/0000-0002-1055-5152; https://orcid.org/0000-0001-9627-3502; https://orcid.org/0000-0002-5957-8611; https://orcid.org/0000-0003-2854-941X; https://orcid.org/0000-0001-6939-5491; https://orcid.org/0000-0003-1509-4575; U-2400-2018; AAK-1876-2021; AAJ-5381-2021; P-5895-2018; AAK-1734-2021; AAK-1686-2021
    Objective: Carpal Tunnel Syndrome (CTS) is the most frequently encountered entrapment neuropathy. 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.

    Angiosarcoma 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.

    Prognostic Value of The Glasgow Prognostic Score For Glioblastoma Multiforme Patients Treated With Radiotherapy and Temozolomide
    (2018) Topkan, Erkan; Selek, Ugur; Ozdemir, Yurday; Yildirim, Berna A.; Guler, Ozan C.; Ciner, Fuat; Mertsoylu, Huseyin; Tufan, Kadir; https://orcid.org/0000-0001-8120-7123; https://orcid.org/0000-0002-2218-2074; https://orcid.org/0000-0001-6661-4185; https://orcid.org/0000-0001-6908-3412; https://orcid.org/0000-0002-1932-9784; https://orcid.org/0000-0003-1509-4575; 29696530; AAG-2213-2021; AAG-5629-2021; V-5717-2017; AAC-5654-2020; M-9530-2014; AAK-1686-2021
    To evaluate the prognostic value of the Glasgow Prognostic Score (GPS), the combination of C-reactive protein (CRP) and albumin, in glioblastoma multiforme (GBM) patients treated with radiotherapy (RT) and concurrent plus adjuvant temozolomide (GPS). Data of newly diagnosed GBM patients treated with partial brain RT and concurrent and adjuvant TMZ were retrospectively analyzed. The patients were grouped into three according to the GPS criteria: GPS-0: CRP < 10 mg/L and albumin > 35 g/L; GPS-1: CRP < 10 mg/L and albumin < 35 g/L or CRP > 10 mg/L and albumin > 35 g/L; and GPS-2: CRP > 10 mg/L and albumin < 35 g/L. Primary end-point was the association between the GPS groups and the overall survival (OS) outcomes. A total of 142 patients were analyzed (median age: 58 years, 66.2% male). There were 64 (45.1%), 40 (28.2%), and 38 (26.7%) patients in GPS-0, GPS-1, and GPS-2 groups, respectively. At median 15.7 months follow-up, the respective median and 5-year OS rates for the whole cohort were 16.2 months (95% CI 12.7-19.7) and 9.5%. In multivariate analyses GPS grouping emerged independently associated with the median OS (P < 0.001) in addition to the extent of surgery (P = 0.032), Karnofsky performance status (P = 0.009), and the Radiation Therapy Oncology Group recursive partitioning analysis (RTOG RPA) classification (P < 0.001). The GPS grouping and the RTOG RPA classification were found to be strongly correlated in prognostic stratification of GBM patients (correlation coefficient: 0.42; P < 0.001). The GPS appeared to be useful in prognostic stratification of GBM patients into three groups with significantly different survival durations resembling the RTOG RPA classification.

    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-1686-2021
    INTRODUCTION 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.
