Item Ethical Discourse of Medical Students on the Phenomenon of Death: A Qualitative Study(2014) Keles, Sukru; Gul, Senay; Yildiz, Abdullah; Karabulut, Seyhan Demir; Eren, Handan; Iskender, Mahinur Durmus; Baykara, Zehra Gocmen; Yalim, Neyyire Yasemin; https://orcid.org/0000-0001-5473-573X; 34018435; AAB-3163-2021The aim of this study is to discover medical students' ideas on the phenomenon of death; produce information on how these students interpret the value-related problems regarding death that they come across in different units of hospitals; and assess this data in ethical terms. This study included a qualitative research in which 12 focus group interviews were conducted with 92 fifth- and sixth-year medical students. Data obtained from interviews were assessed using a thematic content secondary analysis. The main themes were specified according to the medical students' statements and were reviewed under the contexts of the "dying process"; "effects of death"; "attitude and behavior of health professionals"; "seeing a dead body/looking at a dead body"; "accepting death"; and "forms of expressions of death." Medical students' encounters with death in different units of hospitals leads them to question their values and familiarize themselves with the borders of their areas of profession.Item In Vitro Evaluation of E. coli And S. epidermidis Adhesion on Dressing Materials Used in Hypospadias Repair(2014) Soyer, Tutku; Bostanoglu, Ebru; Aslan, Mustafa Kemal; Boybeyi, Ozlem; Demirbilek, Muge; Gocmen, J. Sedef; JWP-3001-2024Background An in vitro study was performed to evaluate the adherence of Escherichia coli and Staphylococcus epidermidis to different dressing materials. Methods Hydrophyl gauze swab (GS), sterile flax swab (FS), and their nitrofurazone (Furacin (R)) absorbed forms (GSF and FSF), sterile paraffin-covered gauze with chlorhexidine acetate (0.5 %) (Bactigrass (R), BG), and semipermeable transparent film gauze (Tegaderm (R), TG) were used in the study. A 1 cm(2) of each material was placed in culture plates, and E. coli ATCC 25922 and S. epidermidis ATCC 12228 were suspended in each plate. After 24, 48 h, and 1 week of incubation period, colony counts were calculated in colony-forming units (CFU) per square centimeter unit. Bacterial adhesion was compared between groups, and each dressing material was also compared for different incubation periods (24, 48 h, and 1 week). Results The colony counts were significantly decreased in GSF and FSF groups (Kruskal-Wallis test, p < 0.05). There was no difference for E. coli adhesion in GS, FS, BG, and TG groups (p > 0.05). The significant difference detected for S. epidermidis adhesion in the first 24 to 48 h could not be detected at the end of a 1-week period. There was no statistical difference in groups when compared for 24-, 48-h, and 1-week periods of incubations (Wilcoxon signed-rank test, p > 0.05). In BG group, E. coli adhesion was increased, and S. epidermidis adhesion was decreased without a significant difference at the end of a 1-week period (p > 0.05). Conclusions Nitrofurazone absorbed sterile gauze materials have less bacterial adhesion. In vitro adhesion of E. coli and S. epidermidis did not differ between the 24-h and 1-week period. E. coli adhesion to BG can be increased if the duration of dressing prolonged up to a 1-week period. Level of Evidence: Not ratable.Item Prostatic Melanosis: A Case Report(2014) Cicek, Tufan; Erinanc, Hilal; Gonulalan, Umut; Sen, Erhan; Ozturk, Bulent; 0000-0003-1944-1722; 0000-0003-1401-6356; AAJ-8576-2021; AAL-1268-2021Prostatic melanosis is characterized by melanocytic proliferation in prostatic stroma and the epithelium. The pathogenesis of the lesion is uncertain. In literature it has been reported as a case associated with prostatic adenocarcinoma before. Primary and metastatic malignant melanoma should be considered in differantial diagnosis of the lesion.Item Disasters As An Ideological Strategy For Governing Neoliberal Urban Transformation in Turkey: Insights from Izmir/Kadifekale(2014) Saracoglu, Cenk; https://orcid.org/0000-0002-4797-4879; 24325244; AAJ-4574-2020Since the turn of the twenty-first century, Turkish cities have undergone large-scale change through a process referred to as urban transformation, involving, notably, the demolition of inner-city low-income settlements. The official authorities and business circles have resorted to various forms of discourse to justify these projects, which have led to the deportation of a significant number of people to peripheral areas. The discourse of natural disasters', for example, suggests that urban transformation is necessary to protect people from some pending event. Probably the most effective application of this discourse has occurred in Izmir, where the risk posed by landslides' has played a critical role in the settlement demolitions conducted in the huge inner-city neighbourhood of Kadifekale. By examining the case of Kadifekale, this paper provide some insights into how natural disasters' serve as a discourse with which to legitimise the neoliberal logic entrenched in the urban transformation process in Turkey.Item Clinical and Cytologic Features of Antibiotic-Resistant Acute Paronychia(2014) Durdu, Murat; Ruocco, Vincenzo; https://orcid.org/0000-0003-1247-3932; 24355264; H-9068-2019Background: Acute paronychia usually is treated as a bacterial infection, but antibiotic-resistant acute paronychia may be caused by other infectious and noninfectious problems. Objective: We sought to describe the clinical, etiologic, cytologic, and therapeutic features of antibiotic-resistant acute paronychia. Methods: A retrospective review of medical records and cytology was performed in 58 patients (age, 1 month-91 years; 36 children and adolescents [62%] and 22 adults [38%]) who had antibiotic-resistant acute paronychias. Results: Causes of paronychia included bacteria (25 patients [43%]), viruses (21 patients [36%]), fungi (5 patients [9%]), drugs (3 patients [5%]), pemphigus vulgaris (3 patients [5%]), and trauma (1 patient [2%]). Diagnostic cytologic findings were noted in 54 patients (93%); no diagnostic cytologic findings were present with drug-induced (3 patients) or traumatic (1 patient) paronychia. The most common predisposing factors were the habits of finger-or thumb-sucking (14 patients [24%]) and nail-biting (11 patients [19%]). Complications included id reaction with erythema multiforme in 3 patients (5%). Limitations: Limitations include retrospective study design from 1 treatment center. Conclusion: Antibiotic-resistant acute paronychia may be infectious or noninfectious. Cytologic examination with Tzanck smear may be useful diagnostically and may prevent unnecessary use of antibiotics and surgical drainage.Item Renal Pseudoaneurysm after Micropercutaneous Nephrolithotomy(2014) Cicek, Tufan; Istanbulluoglu, Okan; Yildirim, Erkan; Buldu, Ibrahim; Kaynar, Mehmet; Ulas, Huseyin; 0000-0002-9057-722X; 0000-0002-6957-9060; ABI-3856-2020Postoperative bleeding due to pseudoaneurysm formation is the major cause of percutaneous kidney interventions. Micro percutaneous nephrolithotomy is a one step procedure that used mostly lower pole stones. There are small series that reports technical feasibility and safety of microperc using the All-seeing needle. Here we state the first report of pseudoaneurysm and its treatment after microperc in the literature.Item Use of Cone-Beam Computed Tomography in Diagnosis of An Otherwise Undetected Periapical Lesion in An Anomalous Tooth(2014) Gulsahi, Ayse; Ates, Ufuk; Tirali, Resmiye Ebru; Cehreli, Sevi Burcak; https://orcid.org/0000-0001-6487-3984; HGA-3970-2022; AAD-2907-2020; AAD-6138-2021Fusion is a developmental anomaly of dental hard tissues. Since dental fusion is characterized by irregular coronal morphology and a complex endodontic anatomy, endodontic therapy of such teeth may present a serious clinical challenge. Cone-beam computed tomography (CBCT) is a useful tool for the management of complex endodontic problems and dental anomalies. In the case presented here, a CBCT scan revealed morphological details as well as the severity of periapical infection that had not been visualized with conventional imaging techniques. The results obtained with detailed imaging led to a change in the treatment plan.Item A Rare Cause of Small Intestinal Obstruction: Obturator Hernia(2014) Karagulle, Erdal; Turk, Emin; Yabanoglu, Hakan; 0000-0002-1161-3369; 0000-0003-4766-3373; AAJ-7865-2021; AAJ-5609-2021Obturator hernia is an uncommon disease and its diagnosis is challenging. It is more prevalent in thin, multiparous, elderly women. In this case report a 93-year-old woman patient with a right-sided strangulated obturator hernia was discussed with review of the relevant literature.Item An Explanatory Item Response Theory Approach for a Computer-Based Case Simulation Test(2014) Kahraman, Nilufer; S-9457-2018Problem: Practitioners working with multiple-choice tests have long utilized Item Response Theory (IRT) models to evaluate the performance of test items for quality assurance. The use of similar applications for performance tests, however, is often encumbered due to the challenges encountered in working with complicated data sets in which local calibrations alone provide a poor model fit. Purpose: The purpose of this study was to investigate whether the item calibration process for a performance test, computer-based case simulations (CCS), taken from the United States Medical Licensing Examination((R)) (USMLE (R)) Step 3((R)) examination may be improved through explanatory IRT models. It was hypothesized that explanatory IRT may help improve data modeling for performance assessment tests by allowing important predictors to be added to a conventional IRT model, which are limited to item predictors alone. Methods: The responses of 767 examinees from a six-item CCS test were modeled using the Partial Credit Model (PCM) and four explanatory model extensions, each incorporating one predictor variable of interest. Predictor variables were the examinees' gender, the order in which examinees encountered an individual item ( item sequence), the time it took each examinee to respond to each item ( response time), and examinees' ability score on the multiple-choice part of the examination. Results: Results demonstrate a superior model fit for the explanatory PCM with examinee ability score from the multiple-choice portion of Step 3. Explanatory IRT model extensions might prove useful in complex performance assessment test settings where item calibrations are often problematic due to short tests and small samples. Recommendations: Findings of this study have great value in practice and implications for researchers working with small or complicated response data. Explanatory IRT methodology not only provides a way to improve data modeling for performance assessment tests but also enhances the inferences made by allowing important person predictors to be incorporated into a conventional IRT model.Item The Effects of Teaching Programming via Scratch on Problem Solving Skills: A Discussion from Learners' Perspective(2014) Kalelioglu, Filiz; Gulbahar, Yasemin; 0000-0002-7729-5674; AAF-8110-2019Computer programming is perceived as an important competence for the development of problem solving skills in addition to logical reasoning. Hence, its integration throughout all educational levels, as well as the early ages, is considered valuable and research studies are carried out to explore the phenomenon in more detail. In light of these facts, this study is an exploratory effort to investigate the effect of Scratch programming on 5th grade primary school students' problem solving skills. Moreover, the researchers wondered what 5th grade primary school students think about programming. This study was carried out in an explanatory sequential mixed methods design with the participation of 49 primary school students. According to the quantitative results, programming in Scratch platform did not cause any significant differences in the problem solving skills of the primary school students. There is only a non-significant increase in the mean of the factor of "self-confidence in their problem solving ability". When the thoughts of the primary students were considered, it can be clearly stated that all the students liked programming and wanted to improve their programming. Finally, most of the students found the Scratch platform easy to use.
