Item Sliding hiatal hernia mimicking a left atrial mass(2019) Kocabas, Umut; Ozkalayci, Flora; Altun, Armagan; 0000-0002-3233-8263; 0000-0001-6424-9399; 32082840; ABB-5844-2020; AAG-5856-2020Item Turkish Board of Neurological Surgery(2019) Bulduk, Erkut Baha; Yilmaz, Cem; 30614509AIM: To provide information on the process and the results of the Turkish Board of Neurological Surgery and increase the relevant awareness. MATERIAL and METHODS: The number of applications to the written and oral board exams organized by the Turkish Neurosurgical Society Proficiency Board since 2006, the number of successful and unsuccessful participants, and the number of the neurosurgery residents and specialists who applied to the exam were evaluated. RESULTS: A total of 554 candidates took the exam since 2006 when the first TBNS was applied. Two hundred and sixty of the candidates were successful (46.9%), and 294 (53.1%) were unsuccessful. Two hundred and forty six (44.4%) of those who took the test were neurosurgeons, 308 (55.6%) were neurosurgery residents who had completed their 3rd year in their training. The highest score in the written exams was 93/100, and the lowest score was 33/100. In verbal exams, a total of 73 candidates participated, and 66 (90.4%) of them were successful while 7 of them (9.6%) were unsuccessful. CONCLUSION: Board exams are inevitable to provide a certain level of education and standardization in the training of neurosurgery. Our duty as neurosurgeons is to participate in these exams and work to increase participation for continuing education.Item The success rate and safety of internal jugular vein catheterization under ultrasound guidance in infants undergoing congenital heart surgery(2019) Altun, Dilek; Nurac, Salih Hakan; Toprak, Verda; Eti, Emine Zeynep; 32082823Background: In this study, we aimed to investigate the effect of central venous catheterization under ultrasound guidance on the success and complication rates in low-weight infants (under 5 kg) undergoing surgery due to congenital heart disease. Methods: A total of 70 infants (38 boys, 32 girls; mean age of patients <1 month was 16.4 +/- 9.5 days [n=20; 28.6%]; 1-7.5 months was 126.3 +/- 47.8 [n=50; 71.4%]) who underwent ultrasound-guided internal jugular venous catheterization between October 2014 and October 2015 were retrospectively analyzed. All catheterizations were done under the guidance of ultrasound by two skilled anesthesiologists. Data including demographic characteristics of the patients, procedural success rate, catheter access time, number of attempts, and complications were recorded. Results: The overall success rate of the procedure was 92.8% (n=65). In 82% of the patients (n=53), the insertion was successful at the first attempt. The mean catheter access time (time from the first puncture to the catheter insertion) was 214 +/- 0.48 sec. Complications were seen in five patients (7.14%), and the body weight of these patients was less than 2,500 g There was no arterial puncture in any patients. One patient (1.42%) developed pneumothorax and four patients (5.7%) developed hematoma due to repeated attempts. Conclusion: Our study results suggest that ultrasound-guided central venous cannulation is a safe and effective technique in pediatric population weighing less than 5 kg undergoing congenital heart surgery.Item The prognostic significance of stage I ovarian clear cell and endometrioid carcinomas arising from endometriotic cysts: is it a myth?(2019) Ayhan, Ali; Akilli, Huseyin; Haberal, Nihan; 30315413PurposeThe aim of this study was to determine the clinicopathologic features and the prognostic significance of Stage I ovarian clear cell and endometrioid carcinomas arising from endometriotic cysts.Materials and methodsPatients with either Stage I ovarian clear cell or endometrioid carcinoma were divided into three groups. *Group 1: Patients with cancers arising from endometriotic cysts *Group 2: Patients with ovarian and pelvic endometriosis *Group 3: Patients without endometriosis Patient characteristics (overall survival and disease-free survival) were compared between groups.ResultsOf the 78 patients who participated in this study, 39 were in group 1, 13 were in group 2, and 26 were in group 3. The mean age in groups 1, 2, and 3 were 46years, 54years, and 48years, respectively (p=0.39). Tumoral characteristics, including capsule rupture, positive cytology, grade, and the presence of synchronous endometrial cancer were similar in both groups. The 5-year overall survival rate in groups 1, 2, and 3 were 100, 90, and 93%, respectively (p=0.4). Moreover, the recurrence rates did not differ significantly between groups. Furthermore, subgroup analysis of clear cell carcinoma and endometrioid adenocarcinoma separately showed no effect of endometriosis on disease-free survival (DFS) or overall survival (OS).ConclusionClear cell or endometrioid ovarian carcinoma arising from ovarian and/or pelvic endometriosis shares the same clinicopathologic characteristics with their counterparts that do not arise from endometriosis and patients have similar overall and disease-free survival.Item Remifentanil based anesthetic management for orchiopexy operation in pediatric patient with congenital hypotonia(2019) Caliskan, Esra; Sener, Mesut; Kirpi, Meltem; Aribogan, Anis; 0000-0001-6497-0610; 30633316; S-8336-2019Item An add-on therapy for neuropathic pain: Infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue(2019) Eker, Hatice Evren; Yalcin Cok, Oya; Bozdodan Ozyilkan, Nesrin; Aribodan, Anis; 30633313In some situations, the cause of the supposed neuropathic pain might be related to abnormal tissue recovery such as scar formation due to wound retraction that might create mechanical compression on the nerve tissue. In this report we describe infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue to reduce mechanical stress in 3 patients. The infiltration technique might resolve the tension of the contracted scar tissue by tearing the adhesions and the eliminated mechanical compression would reduce the pressure on nerve tissue and hence neuropathic pain symptoms.Item Young tableaux and Arf partitions(2019) Tutas, Nesrin; Karakas, Halil İbrahim; Gumusbas, NihalThe aim of this work is to exhibit some relations between partitions of natural numbers and Arf semigroups. We also give characterizations of Arf semigroups via the hook-sets of Young tableaux of partitions.Item An Inquiry into the Underlying Reasons for the Impact of Technology Enhanced Problem-Based Learning Activities on Students' Attitudes and Achievement(2019) Cetin, Yucel; Mirasyedioglu, Seref; Cakiroglu, ErdincPurpose: In the constantly changing and evolving world of today, there is a need to raise individuals who are able to renew themselves, learn autonomously, and have higher order thinking skills such as critical thinking and deducing. The purpose of the present study is to investigate the effects of Technology Enhanced Problem-Based Learning Activities (TEPLA), developed with regard to the aforementioned need, on learners' attitudes towards mathematics and academic achievement in mathematics through qualitative data in order to designate the underlying causes of these effects. Method: In the research, conducted as a case study, the analysis of the written and oral interviews were held with students using "Student Interview Form" in order to analyze the effect of TEPLA on the attitudes towards mathematics and mathematics achievements of study group students who were applied TEPLA by the first author. Findings: The analysis revealed two main dimensions affecting the association between TEPLA and learners' attitudes towards mathematics: Affection and Usefulness, which comprised five and three distinct reasons, respectively. On the other hand, ten factors were defined to account for the impact of using TEPLA on learners' mathematics achievement. Implications for Research and Practice: The research findings suggested that learners found TEPLA interesting and meaningful. Thus, it can be suggested that the impact of TEPLA on learner motivation can also be investigated using a motivation scale. Moreover, learners stated during interviews that they achieved retention in learning thanks to TEPLA. Thus, the finding regarding TEPLA's impact on retention can be further investigated quantitatively. (c) 2019 Ani Publishing Ltd.

Materials and methods: Fifty consecutive acute ischemic stroke patients admitted to the stroke unit were recruited. Patients were classified by two stroke and two general neurologists, each from different medical centers, according to TOAST followed by the CCS. Each neurologist was assessed for consistency and compliance in pairs. Concordance among all four neurologists was investigated and evaluated using the kappa (kappa) value. Results: The kappa (kappa) value of diagnostic compliance between stroke neurologists was 0.61 (95% CI: 0.45-0.77) for TOAST and 0.78 (95% CI: 0.62-0.94) for CSS-5. The kappa (kappa) value was 0.64 (95% CI: 0.48-0.80) for TOAST and 0.75 (95% CI: 0.60-0.91) for CCS-5 for general neurologists. Compliance was moderate [kappa: 0.59 (95% CI: 0.52-0.65)] for TOAST and was strong [kappa: 0.75 (95% CI: 0.68-0.81)] for CCS-5 for all 4 neurologists. 'Cardioembolism' (91.04%) had the highest compliance in both systems. The frequency of the group with 'undetermined etiologies' was less in the CCS (26%) compared to TOAST. Conclusion: The CCS system improved compliance in both stroke and general neurologists compared with TOAST. This suggests that the automatic, evidence-based, easily reproducible CCS system was superior to the TOAST system.
