        Çağrı Yayla,Kaan Okyay,Asife Şahinarslan,Akın Yılmaz,Atiye Seda Yar Sağlam,Azmi Eyiol,Hasan Ata Bolayır,Burak Sezenöz,Sevda Menevşe,Atiye Çengel 대한심장학회 2016 Korean Circulation Journal Vol.46 No.5

        Background and Objectives: Genetic predisposition is an important risk factor for coronary artery disease (CAD). In this study, we aimed to evaluate the impact of rs10757274 and rs2383206 polymorphisms in chromosome 9p21 on presence and severity of CAD in a Turkish population. Subjects and Methods: A total of 646 patients who underwent coronary angiography were included in this study. Coronary vessel score and Gensini score were calculated to assess the angiographic severity of CAD. Alleles of AA, AG, and GG were determined for rs10757274 (polymorphism-1) and rs2383206 (polymorphism-2) polymorphisms located in chromosome 9p21 from the blood samples. Results: There was a significant difference between the alleles in polymorphism-1 in the presence of coronary artery disease (38.9% in AA, 48.0% in GG and 56.4% in AG, p=0.017). However, there was no difference between the alleles in polymorphism-2. According to vessel scores, there was a significant difference between the alleles in polymorphism-1 (AA 0.71±1.04, GG 0.88±1.07, AG 1.06±1.12, p=0.018). In polymorphism-2, vessel scores did not show a difference between the alleles. In polymorphism-1, there was a significant difference in Gensini score (p=0.041). Gensini scores did not differ between the alleles in polymorphism-2 (p>0.05 for all). In multivariate analyses, none of the alleles was an independent factor for presence of CAD. Conclusion: The presence of rs10757274 polymorphism including AG allele in chromosome 9p21 was related to CAD. However, this relationship was not independent of other cardiovascular risk factors.

        Evaluation of the accuracy of three different intraoral scanners for endocrown digital impression: An in vitro study

        Çağrı Ural,박지만,Necati Kaleli,Esma Çağlayan 대한치과보철학회 2020 대한치과보철학회지 Vol.58 No.4

        Purpose: The aim of this in vitro study was to evaluate the accuracy of three different intraoral scanners (IOSs) on digital impressions of different types of endocrown cavity preparations. Materials and methods: Two human mandibular molar teeth were prepared with different endocrown abutment designs: one with a buccal wall (Class 2) and the other without a buccal wall (Class 3). Both cavity designs were scanned using a reference desktop scanner (E3) and three different intraoral scanners: Trios3 (TRI group), Cerec Omnicam (CER group), and i500 (I5 group). The obtained Standard Tessellation Language (.stl) datasets were exported to metrology software. The precision was evaluated based on deviations among repeated scan models recorded by each IOS. The trueness was evaluated based on deviations between the reference data and repeated scans. For detecting interaction, data were statistically analyzed using a univariate analysis of variance (ANOVA) and for analyzing the comparison of the test groups data were analyzed by one-way ANOVA and post-hoc Tukey test at the significance level of .05. Results: The deviation values for both cavity designs in the I5 group were significantly lower than those in the other IOS groups in terms of trueness. For both cavity designs, the TRI group exhibited better precision than the other IOS groups. Conclusion: Different technologies of IOS device’s and different endocrown prepration designs affected the accuracy of the digital scans.

        Distinctive Characteristic Features of Intramedullary Hemangiopericytomas

        Cezmi Çağrı Türk,Niyazi Nefi Kara,Dinç Süren,Çağatay Özdöl,Tolga Gediz,Sevim Yıldız3 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.4

        Study Design: The retrospective analysis of intramedullary hemangiopericytomas (HPCs) was performed, and the entity was discussed in accordance with the literature findings. Purpose: This study aimed at defining distinctive characteristic features of intramedullary HPC with respect to surgical approach and prognosis. Overview of Literature: Intramedullary HPCs are extremely rare tumors. They originate from capillary pericytes, supposedly follow the vessels over the spinal cord, and infiltrate deep into the spinal cord without a distinct plane. Their treatments and prognosis are not well-defined in the literature. Methods: Our database was retrospectively reviewed for the cases of HPCs. Later on, a literature search was performed to reveal all reported cases of intramedullary HPCs. The following key words were searched in PubMed databases: “hemangiopericytoma and intramedullary,” “hemangiopericytoma and spine (spinal) and intradural,” and “hemangiopericytoma and spinal cord.” The articles were reviewed for patients’ demographics features, imaging characteristics, tumor-specific factors (surgical technique, pathological descriptions, and world health organization grades), and postoperative course and prognosis (adjuvant therapies, recurrences, complications, and mortalities). Results: A total of seven patients (three male and four female) was reached, with their ages ranging from 15 to 80 years (mean, 32.5 years). The tumors were located majorly in thoracic region (5/7, 71.4%), and only two cases were in the cervical region (2/7, 28.6%). All tumors were completely removed, and only two cases received radiotherapy. No recurrence was reported. Conclusions: Complete resection of the intramedullary HPCs seems to be the best management strategy for long-term and recurrence- free survival and in alleviating further need for radiotherapy.

        Aykan Ahmet Çağrı,Gökdeniz Tayyar,Gül İlker,Kalaycıoğlu Ezgi,Karabay Can Yücel,Boyacı Faruk,Hatem Engin,Weingart Scott D.,Dursun İhsan 대한응급의학회 2023 Clinical and Experimental Emergency Medicine Vol.10 No.3

        Objective: Severe pulmonary embolism (PE) has a high mortality rate, which can be lowered by thrombolytic therapy (TT). However, full-dose TT is associated with major complications, including life-threatening bleeding. The aim of this study was to explore the efficacy and safety of extended, low-dose administration of tissue plasminogen activator (tPA) on in-hospital mortality and outcomes in massive PE. Methods: This was a single-center, prospective cohort trial at a tertiary university hospital. A total of 37 consecutive patients with massive PE were included. A peripheral intravenous infusion was used to administer 25 mg of tPA over 6 hours. The primary endpoints were in-hospital mortality, major complications, pulmonary hypertension, and right ventricular dysfunction. The secondary endpoints were 6-month mortality and pulmonary hypertension and right ventricular dysfunction 6 months after the PE. Results: The mean age of the patients was 68.76±14.54 years. The mean pulmonary artery systolic pressure (PASP; 56.51±7.34 mmHg vs. 34.16±2.81 mmHg, P<0.001) and right/left ventricle

        Comparison of different digital shade selection methodologies in terms of accuracy

        Nurşen Şahin,Çağrı Ural 대한치과보철학회 2024 The Journal of Advanced Prosthodontics Vol.16 No.1

        Purpose. The aim of this stuldy was to compare the clinical marginal fit of CAD-CAM inlays obtained from intraoral digital impression or addition silicone impression techniques. Materials and Methods. The study included 31 inlays for prosthodontics purposes of 31 patients: 15 based on intraoral digital impressions (DI group); and 16 based on a conventional impression technique (CI group). Inlays included occlusal and a non-occlusal surface. Inlays were milled in ceramic. The inlay-teeth interface was replicated by placing each inlay in its corresponding uncemented clinical preparation and taking interface impressions with silicone material from occlusal and free surfaces. Interface analysis was made using white light confocal microscopy (WLCM) (scanning area: 694 × 510 μm2) from the impression samples. The gap size and the inlay overextension were measured from the microscopy topographies. For analytical purposes (i.e., 95-%-confidence intervals calculations and P-value calculations), the procedure REGRESS in SUDAAN was used to account for clustering (i.e., multiple measurements). For p-value calculation, the log transformation of the dependent variables was used to normalize the distributions. Results. Marginal fit values for occlusal and free surfaces were affected by the type of impression. There were no differences between surfaces (occlusal vs. free). Gap obtained for DI group was 164 ± 84 μm and that for CI group was 209 ± 104 μm, and there were statistical differences between them (p = .041). Mean overextension values were 60 ± 59 μm for DI group and 67 ± 73 μm for CI group, and there were no differences between then (p = .553). Conclusion. Digital impression achieved inlays with higher clinical marginal fit and performed better than the conventional silicone materials.

        Intradetrusor Injections of Onabotulinum Toxin-A in Children With Urinary Incontinence due to Neurogenic Detrusor Overactivity Refractory to Antimuscarinic Treatment

        Tufan Tarcan,Cem Akbal,Çağrı A. Şekerci,Tuncay Top,Ferruh Şimşek 대한비뇨의학회 2014 Investigative and Clinical Urology Vol.55 No.4

        Purpose: This was a prospective single-arm study to assess the efficacy and safety ofintradetrusor injections of onabotulinum toxin-A in children with urinary incontinenceassociated with neurogenic detrusor overactivity due to myelomeningocele. All patientshad failed the first-line treatment of a combination of oral antimuscarinics andintermittent catheterization. Materials and Methods: The study group consisted of 31 children with myelomeningocelewith a mean age of 7.95 years (range, 5–13 years) who were followed up for a meanof 29 weeks. The amount of onabotulinum toxin A injected was 10 U/kg with a maximaldose of 300 U. There were 20 to 30 injection sites with rigid cystoscopic guidance undergeneral anesthesia. Results: Thirty of 31 patients reported dryness between intermittent catheterizationintervals. The mean reduction in maximum detrusor pressure and the mean increasein maximum cystometric capacity from baseline were 53% and 51.5%, respectively, 6weeks after injection. We found a 324% increase in mean bladder compliance and a 57%increase in mean intermittent catheterization volumes. The mean duration of efficacywas 28 weeks with a single injection and 36 weeks for repeated injections (minimum,16 weeks; maximum, 52 weeks). The mean time interval between repeated onabotulinumtoxin-A injections was 7 months (maximum, 13 months). Intradetrusor injectionsof onabotulinum toxin-A were well tolerated. Conclusions: Onabotulinum toxin-A injections into the bladder wall provide a significantsymptomatic and urodynamic improvement in children with neurogenic detrusoroveractivity due to myelomeningocele who are on intermittent catheterization. The treatment seems to be safe and very well tolerated.

        Serum Irisin Level Can Predict the Severity of Coronary Artery Disease in Patients with Stable Angina

        Tolga Han Efe,Çağrı Yayla,Burak Açar,Göktuğ Ertem,Kadriye Gayretli Yayla,Engin Algül,Sefa Ünal,Murat Bilgin,Tolga Çimen,Özgür Kirbaş,Ekrem Yeter 대한심장학회 2017 Korean Circulation Journal Vol.47 No.1

        Background and Objectives: The recently discovered myokine irisin has a proposed role in adipose tissue metabolism. The aim of this study was to evaluate the relationship between serum irisin level and the coronary artery severity in patients with stable coronary artery disease (CAD). Subjects and Methods: Sixty-three patients who underwent coronary angiography (CA) diagnosed with stable CAD and twenty-six patients with normal coronary artery (NCA) were enrolled in the study. Stable CAD patients were divided into two groups as high synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score (≥23) and lower SYNTAX score (<23). Serum irisin level measurement was carried out using human irisin colorimetric enzyme-linked immunosorbent assay (ELISA) commercial kit (AG-45A-0046EK-KI01, Adipogen, San Diego, CA, USA) as recommended by the manufacturer’s protocol. Results: The patients with stable CAD with a higher SYNTAX score (score ≥23) had significantly lower serum irisin levels (127.91±55.38 ng/mL), as compared the patients with a low SYNTAX score (score <23) (224.69±92.99 ng/mL) and control group (299.54±123.20 ng/mL). Irisin levels showed significant differences between all groups (p<0.001). Conclusion: Serum irisin level is an independent predictor of coronary artery severity in patients with stable CAD.

        Giant Basal Cell Carcinoma Causing Axillary Contracture: A Case Report of an Unusual Localization of an Advanced Case

        ( Abbas Albayati ),( Burak Özkan ),( Merih Tepeoğlu ),( Çağrı A. Uysal ) 대한피부과학회 2023 Annals of Dermatology Vol.35 No.7

        Basal cell carcinoma (BCC) is the most common type of non-melanoma skin cancer. Although BCC arises most commonly in sun-exposed areas of the body, such as the head and neck, it infrequently can be seen in sun-protected parts as well. Axilla is one of the least encountered areas of BCC. Delay in the diagnosis or management alongside negligence of the patient can lead to a tumor reaching a giant size. We report a case of giant axillary BCC in a 59-years old female patient with no known risk factors for skin cancers. The tumor was excised with wide margins, and the tissue defect was reconstructed with latissimus dorsi musculocutaneous flap. A 3-year follow-up did not show any sign of recurrence or metastasis.

        Stronger Together in Lab: Multi-Center and Laboratory Spine Studies are Closer to Publication than Single-Center and Clinical Spine Studies: Snapshot of Annual Meetings of the Spine Society of Europe

        Özcan-Ekşi Emel Ece,Canbolat Çağrı,Ayhan Selim,Ekşi Murat Şakir 대한척추외과학회 2020 Asian Spine Journal Vol.14 No.5

        Study Design: This is a cross-sectional study of literature databases.Purpose: The purpose of this study is to analyze the predictive factors for the publication rates of spine studies.Overview of Literature: Spine research has garnered worldwide interest due to the increased number of spinal disorders in aging population.Methods: We evaluated the abstracts presented at the annual meetings of the Spine Society of Europe between 2009 and 2012. Additionally, we recorded presentation categories, study designs, research types, random assignments of the subjects, single- or multi-center- based methodologies, and significance of the results.Results: We evaluated 965 abstracts, 53.5% of which were published in peer-reviewed journals. Publication rates were significantly higher for oral presentations (62.9%) and prospective studies (61.3%) as compared to the poster presentations (46.7%) and retrospective studies (44.2%), respectively (p <0.001). Clinical studies contributed to about 86.1% of the published abstracts. However, publication rates were significantly higher for laboratory studies as compared to clinical studies (70.1% vs. 50.8%, p <0.001). Multi-center studies were closer to publication than single-center studies (67.1% vs. 52.2%, p =0.009). Our study demonstrated that multi-center studies (odds ratio, 1.81; p =0.016) and laboratory studies (odds ratio, 2.60; p <0.001) are more likely to be published.Conclusions: Multi-center collaborations dedicated to experimental studies in spine research are highly ranked and more likely to be published in peer-reviewed journals.
