Peer feedback through SNSs (Social Networking Sites): Pre-service teachers’ views about using Facebook for peer feedback on microteachings

The aim of this study is to determine the views of pre-service teachers on the use of Facebook for providing peer feedback on their microteachings. To serve this aim, a case study was conducted with 38 English language pre-service teachers. Firstly, these pre-service teachers did their microteachings and uploaded the videos of these microteachings to a Facebook group opened by the researchers. Then, it was provided that the members of this Facebook group which were their classmates comment on these videos. In order to collect data, an open-ended questionnaire which was formed by the researchers was conducted to the pre-service teachers. The findings showed that the pre-service teachers were positive towards using peer feedback through Facebook (PFF after then) in teacher education. PFF helped them be aware of their weaknesses and strengths in their both pedagogic and linguistic knowledge. Thus, it was suggested that SNS like Facebook could be benefited in teacher education to improve both pedagogic and content knowledge of pre-service teachers. © 2016, Ankara University.

Solitary Fibrous Tumors of Chest: Another Look with the Oncologic Perspective

Solitary fibrous tumors are mesenchymal lesions that arise at a variety of sites, most commonly the pleura. Most patients are asymptomatic at diagnosis, with lesions being detected incidentally. Nevertheless, some patients present due to symptoms from local tumor compression (eg. of the airways and pulmonary parenchyma). Furthermore, radiological methods are not always conclusive in making a diagnosis, and thus, pathological analysis is often required. In the past three decades, immunohistochemical techniques have provided a gold standard in solitary fibrous tumor diagnosis. The signature marker of solitary fibrous tumor is the presence of the NAB2-STAT6 fusion that can be reliably detected with a STAT6 antibody. While solitary fibrous tumors are most often benign, they can be malignant in 10-20% of the cases. Unfortunately, histological parameters are not always predictive of benign vs malignant solitary fibrous tumors. As solitary fibrous tumors are generally regarded as relatively chemoresistant tumors; treatment is often limited to localized treatment modalities. The optimal treatment of solitary fibrous tumors appears to be complete surgical resection for both primary and local recurrent disease. However, in cases of suboptimal resection, large disease burden, or advanced recurrence, a multidisciplinary approach may be preferable. Specifically, radiotherapy for inoperable local disease can provide palliation/shrinkage. Given their sometimes -unpredictable and often- protracted clinical course, long-term follow-up post-resection is recommended

The effect of different teaching methods to understanding of chemical equilibrium at micro level [Kimyasal denge konusunun mikro boyutta anlaşılmasına farklı öğretim yöntemlerinin etkisi1]

The aim of this study is to determine students’ understandings related to chemical equilibrium at micro level by using different teaching methods. It was used quasi-experimental method with pre-and posttest. The sample was comprised of 90 first class science teacher education program students. It was studied with three groups: cooperative learning group (student teams achievement divisions method, STAD) (CLG, N=22), cooperative-model group (STAD + models) (CMG, N=41) and control group (CG, N=27). In order to compare the groups it was used a multiple choices Particulate Nature of Matter Test (PNMTa) related to chemical equilibrium. The PNMTa consists of six questions. For determining students’ conceptual understandings related to the subject, the PNMTa was rearranged as open-ended with removing choices (PNMTb). According to ANOVA results, it was not found significant difference among groups. Also, according to open-ended question, it was determined some misconceptions related to topic. © 2017, Ankara University. All rights reserved

Effect of prophylactic antibiotic use in the development of antibiotic resistance in children with recurrent urinary tract infections [Tekrarlayan idrar yolu enfeksiyonunda profilaktik amaçlı antibiyotik kullanımının çocuklarda antibiyotik direnç gelişimine etkisi]

Aim: Although prophylactic antibiotic treatment is still debatable, it is currently in use in recurrent urinary tract infections (UTIs). In the present study, we aimed to observe if prophylactic antibiotic use had any effect on the development of antibiotic resistance in patients with recurrent UTIs who we followed up in our clinic. Methods: The present study was performed on patients aged between one month and 16 years, who had recurrent UTIs, and were followed up by the Department of Pediatrics at Bülent Ecevit University Medical School. Patient files were retrospectively reviewed, and 50 patients who received antibiotic prophylaxis and 100 patients without prophylaxis were enrolled in the study. Urinary tests, subsequent urinary culture results, and antibiotic resistances were compared between the groups. Results: The mean age was 42.7±44.2 months. The most frequently cultured isolated bacterium was Escherichia coli (E. coli) (58.4%). No difference was determined in bacteria in cultures between prophylaxis receivers and non-receivers. Isolation rate of E. coli was higher in urinary cultures in females than in males (p<0.001). When antibiotic resistance of all urinary culture-isolated bacteria was compared between the two groups, there was no statistically significant difference. However, an increased resistance against amoxicillin/clavulanic acid, ceftriaxone, and piperacillin was determined in prophylaxis group in whom E. coli was grown. In this study, general antibiotic resistance was most frequently observed against ampicillin (71.9%). Conclusion: In the present study, we observed that prophylaxis did not contribute so much to resistance other than E. coli. We recommend not preferring antibiotics which have increased resistance in our institution especially in children receiving prophylaxis for empirical treatment. © 2017 by The Medical Bulletin of University of Health Sciences Haseki Training and Research Hospital The Medical Bulletin of Haseki published by Galenos Yayınevi
