Item A Rare Case of Ectopia Cordis with Double Outlet Right Ventricle(2019) Silahlı, Musa; Gokmen, Zeynel; Gokdemir, Mahmut; 0000-0003-0944-7178Ectopiacordis is a rare anomaly. It is described that hearth is placed as partially or totally outside of thoracic cavity. Sometimes this can be accompanied liver and other organs such as intestine. Congenital heart defects are also likely to accompany to this situation. So, we present an ectopiacordis with double outlet right ventricule case who has lived for 121 days in neonatal intensive care unit.Item Assesment of Spatial QRS-T Angle in Patients with Cardiac Syndrome X(2019) Muderrisoglu, Mustafa; Muderrisoglu, Haldun; 0000-0002-9635-6313; AAG-8233-2020Objective: Cardiac syndrome x (CSX) is defined as typical exertional angina, one or more abnormal cardiac stress test(s), and normal coronary arteries after exclusion of spontaneous or inducible epicardial coronary spasm. The aim of this study was to investigate cardiovascular adverse events risks in patients with CSX. For this purpose, spatial QRS-T angle that is predictor of these risks was evaluated in patients with CSX and control subjects. Methods: In a retrospective study, a total of 179 subjects (95 patients with CSX, 84 control) were examined. Control subjects had a normal coronary computed tomography. Spatial QRS-T angle value was calculated and compared in patients with CSX and control group, p values <0.05 were considered as statistically significant. Results: There was a statistically significant difference between the groups in terms of spatial QRS-T angle values [control group spatial QRS-T angle value median 35 (12.5 - 60), CSX group spatial QRS-T angle value median 51 (27 - 115), p<0.001]. Conclusion: According to our results, spatial QRS-T angle value was elevated in patients with CSX than in normal population. Furthermore, these results may indirectly suggest that the risk of adverse cardiac events may be increased in patients with CSX.Item The role of PET-CT in the evaluation of the response of the vertebra metastases in stereotactic radiosurgery(2019) Ozdemir, Yurday; Torun, Nese; Topkan, Erkan; 0000-0001-8120-7123; AAG-5629-2021; AAG-2213-2021Purpose: The aim of this study was to evaluate the role of positron emission tomography in assessing the response of stereotactic radiosurgery (SRS) for vertebral metastases(VM). Materials and Methods: Patients who received 16 Gy or 18 Gy SRS with no history of vertebral compression fracture, proven histologies except small-cell lung carcinoma and hematologic malignancies which are known as radio sensitive tumors, available pre- and post SRS PET images were included. All vertebral segments were categorized according to spinal instability neoplastic score in terms of stability and PET Response Criteria in Solid Tumors (PERCIST) criteria was utilized for treatment response. Results: Seventy-five patients with 119 VS (101 single, 9 double VS) received SRS. Breast cancer (66.7%) was the commonest pathology. Most patients (70.6%) had SINS 06.The local control was achieved in 87.4% VS with a 1-year local relapse -free survival rate of 92.5%. The median PET-CT time for the first SRS response assessment was 3-months (range:1-3.5 months) and there were only 4 (3.3%)local relapses in contrast to the positive responses in the remainders (30.3% complete, 43.7% partial responses and 22.7% stabil disease). While there were 11 local relapses in the last PET-CT response, no patient experienced any relapse complete response was achieved in the first PET-CT.Complete response in the first PET-CT was correlated with positive response in the last PET CT also. Conclusion: First PET-CT response after SRS seems to be valuable in anticipation of both the final vertebral response status and planning of alternative interventions for non-responders.Item Turkish Thoracic Society Consensus Report: Interpretation of Spirometry(2019) Ulubay, Gaye; Dilektasli, Asli Gorek; Borekci, Sermin; Yildiz, Oznur; Kiyan, Esen; Gemicioglu, Bilun; Saryal, Sevgi; 0000-0003-2478-9985; 30664428; AAB-5064-2021Currently, the criteria for applying and evaluating spirometer measurements have been defined by American and European Respiratory Societies. Several pulmonary function test laboratories in Turkey as well as in the world use these standards. However, different interpretation results are observed in different pulmonary function test laboratories. This report is prepared to provide a basis for a standardized asssessment in our pulmonary function test in our country.Item Evaluation of Blood Culture Practices: Use of System (Epicenter) Data(2019) Basustaoglu, Ahmet; Suzuk Yildiz, Serap; Mumcuoglu, Ipek; Karahan, Zeynep Ceren; Ogunc, Dilara; Kaleli, Ilknur; Kursun, Senol; Evren, Ebru; Ozhak, Baysal Betil; Demir, Melek; Murray, Patrick; 30683035Sepsis is a serious clinical problem and estimated to be responsible for 18 million annual deaths worldwide. Therefore, the use and the rapid processing of blood cultures are important for the transition from empiric therapy to directed therapy. The aim of this study was to assess the best blood culture practices in Turkey. We have examined the collection practices and techniques at four different hospitals, and a total of 165.443 blood culture bottles were evaluated (2013-2015). At the preanalytical phase most of the data which were important and which could support hospital quality systems/practices were not entered into the HIS and EpiCenter system. At the analytical phase loading of the bottles and removal of positive bottles primarily occurred between 6:00 and 9:00 AM but the positivity rate of the bottles showed a homogeneous distribution throughout the day. In other words, there were significant delays at processing positive blood culture bottles related to laboratory workers. The effect of education regarding best practices, transition from single bottle to two bottle cultures was successful in all hospitals. Single bottle usage decreased below 10% in all hospitals. Significantly more positive cultures were detected at multiple cultures when compared with the single bottle collection practice. In retrospective patient records, it was seen that all the laboratories reported the results of Gram staining to the clinics. However, these data were not recorded to the Epicenter. The contamination rates of Ankara Numune Hospital and Akdeniz University Faculty of Medicine Hospital are 6.2% and 5.4% respectively, contamination rates were not reported in other hospitals. The most common isolates detected in blood cultures were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, Staphylococcus aureus, and Acinetobacter baumannii. The mean time for the detection of these organisms were less than 20 hours in the aerobic bottle and anaerobic bottles. A total of 79.6% of facultative anaerobic isolates were detected in both bottles; 9.8% were detected only in the aerobic bottles; 10.6% of the isolates were detected only in the anaerobic bottles. As a result, the educational efforts in Turkey have met with success for transition from collecting single bottle blood culture sets to two bottle blood cultures. However, further efforts are needed to increase the number of blood culture sets collected during a 24 hour's period. In addition, errors at the preanalytical, analytical and postanalytical periods (taking samples, loading bottles into the system and processing positive blood cultures) should be eliminated.Item Use of psychodrama method in trainings about child abuse and neglect(2019) Dagli, Figen Sahin; Taskiran, Candan; Krespi, Margorit Rita; Gokler, BaharObjective: Child abuse and neglect should be a main topic in trainings of students who have a possibility to encounter a neglected and abused child in their future professional lives. Use of psychodrama in training such an important and sensitive subject is a novel approach. In this study, it is aimed to evaluate the effects of psychodrama method for the training about child abuse and neglect given to university students. Method: In this training, a group of 11 students attended the 16 week course, once a week for 2,5 hours. The effects of this training were evaluated by quantitative and qualitative methods. Results: For quantitative analysis pre and post training knowledge tests revealed scores of 33 and 39 respectively. The difference was statistically significant (p<0.05). Awareness test scores for pre and post training evaluation were 85 and 89 respectively. Although there was an increase after training this increase was not statistically significant (p=0.65). Focus group interview which was performed for qualitative analysis revealed that the training increased the participants' awareness and empathy, made them more sensitive for the news about children and child abuse, taught them not to judge people, encouraged them for their future career and made them understand the importance of multidisciplinary approach. Discussion: These perceived benefits indicate that psychodrama method may be used to teach the topic of child abuse and neglect.Item An optimization for milling operation of Kevlar fiber-epoxy composite material using factorial design and goal programming methods(2019) Ic, Yusuf Tansel; Elaldi, Faruk; Kececi, Baris; Uzun, Gozde Onder; Limoncuoglu, Nur; Aksoy, Irem; 0000-0003-0592-6868; 0000-0002-2730-5993; AAI-1081-2020; AAG-5060-2019; F-1639-2011; AAC-4793-2019Kevlar fiber-epoxy composite material is extensively used in manufacturing areas because of the advantages of composite material's characteristics. It is usually processed by traditional machining methods but the drawbacks for determination of optimum cutting parameters might cause some material deformations during machining process. In this study, the cutting parameters are concurrently optimized by using the integrated 2k factorial design and goal programming methods for minimum delamination and minimum surface roughness of Kevlar fiber-epoxy composite and the best machining parameters have been obtained for the material. The results were compared with the results of the multi-criteria decision-based Taguchi methods.Item Clinical Features of Patients with Allergic Rhinitis and Evaluation of Adenoid Hypertrophy as a Comorbidity(2019) Sancakli, Ozlem; Belverenli, H.Objective: The nasal cavity is anatomically and functionally communicates with eyes, paranasal sinuses, nasopharynx, middle ear and lower airways. Therefore, comorbid diseases such as asthma, chronic sinusitis, adenoid hypertrophy allergic conjunctivitis are common in patients with allergic rhinitis. In our study, we aimed to evaluate the frequency of comorbid diseases, clinical features of patients who referred to our outpatient clinic with allergic rhinitis. Method: The study included children aged between 3-17 years who were diagnosed with moderate to severe allergic rhinitis between September 2015 and March 2016 in our pediatric allergy outpatient clinic. Patient files were retrospectively reviewed; comorbid diseases, family history, eosinophil percentage, total IgE level and allergy test results and the number of drugs used were recorded. In the first month of the treatment, visual analog scale was used to score the symptoms. P< 0.05 was considered significant in the statistical analysis. Results: A total of 106 patients (33 female, 73 male) with respective median ages of 7.25 and 5.13 years [range: 3.0-17.0, years] were included in the study. In 84.9% of our patients, skin test was positive, and in 69.8% of the patients the symptoms persisted for more than 2 years. The most common comorbid diseases were asthma (52.8%) and adenoid hypertrophy (30.2%). In our study, the incidence of adenoid hypertrophy was higher and total IgE levels were lower in the skin test-negative group (p=0.019, p=0.027). Conclusion: In our study, the most common comorbid diseases in patients with allergic rhinitis were asthma and adenoid hypertrophy, and in the skin test-negative group adenoid hypertrophy was more frequent.Item The Necessity of Sector Carrying Capacity in Multinational Companies' FDI Location Choice(2019) Baskici, Cigdem; Ercil, Yavuz; AAI-6607-2020The aim of this study is to define the carrying capacity as a new criterion in multinational companies' foreign direct investment (FDI) location choice. The validity of such a definition requires the existence of a causal relationship between FDI and the number of companies at the investment location. As carrying capacity is a function of the sector population, FDI refers to the decisions of foreign investors regarding location choice. With this in mind, the company numbers and FDI data used belonging to 34 sub-sectors of Agriculture, Industry and Services sectors in Turkey between the years of 2006-2016 were analyzed. The Granger causality test was applied to investigate the causal relationship between the company numbers and FDI. As a result of the findings, a causality relationship between the number of companies and FDI was determined in 29 of the 34 sub-sectors. A causality relationship could not be found in 2 sub-sectors. Analysis was not possible in the remaining 3 sub-sectors because of a lack of data. The results show that carrying capacity can be used as decision criterion in multinational companies' FDI location choice. In addition to this main result of the study, predictions for the investment decision are presented in the light of the analyses along with evaluations of the carrying capacity of the Agriculture, Industrial and Services sectors.Item Evaluation of Blood Transfusion Applications in Newborn Intensive Care Unit; Single Center Experience(2019) Turhan, AliINTRODUCTION: The frequency of transfusion is high in infants admitted to neonatal intensive care unit (NICU). There is a higher risk of transfusion complications compared to other age groups, and there are many special considerations for transfusion in neonates. The aim of this study was to investigate the records of infants who had blood product transfusions in NICU, to investigate which patient groups were transfused, the characteristics of the blood products used and the current transfusion practices. MATERIALS and METHODS: Between November 2013 and May 2018, the records of 968 newborn infants admitted to the Istanbul Hospital NICU of Baskent University School of Medicine were retrospectively analyzed. RESULTS: Of the babies, 43.8% were female, median birth weight was 2598 (1478-3228) grams, median birth week was 36.5 (30-39) weeks and median hospitalization days were 32 (15-67.5) days. The most commonly used blood group was A Rh (+), the least used blood group AB Rh (-). 39.9% of the transfusions were fresh frozen plasma, 36.2% erythrocyte and 23.5% platelet suspension. In addition to prematurity and related diseases, diseases requiring surgery of central nervous system, congenital heart or gastrointestinal system diseases were the most common transfused group. According to term babies, the rate of use of thrombocyte suspension was higher in preterm infants, however the rate of use of other products was similar. CONCLUSIONS: Knowledge of the selection, preparation of blood products to be used in transfusion and the specific methods for reducing the risks of transfusion will reduce the potential risks and increase the safety of transfusion.
