Öğe The Effects of a New Hemostatic Agent on Hearing in Rats(Aves, 2010) Kalcioglu, M. Tayyar; Bayindir, Tuba; Iraz, Mustafa; Kaya, Serdar; Can, SermetObjective: Ankaferd Blood Stopper (ABS), a standardized mixture of five plants, has been used as a hemostatic agent. Studies have shown the hemostatic effectivity of this agent that suggests a potential usage in otological surgeries. However,side effects on hearing of this agent are unknown. In this study, hearing affection of local and systemic usage of ABS was investigated by using distortion product otoacoustic emissions (DPOAEs). Materials and Methods: Thirty-two male Wistar rats were used. The animals were divided into four groups. Baseline DPOAE measurements were performed. Subsequently, intratympanic ABS administration to the firstgroup and intratympanic saline administration to the second group were performed. Intraperitoneal ABS was injected to the third group. The fourth group was not administered any intervention. Side effects of ABS on hearing were evaluated by repeated DPOAE measurements carried out before and at 1st, 7th, and 40th days following the applications. Results: On days 7 and 40; measurement parameters of DPgrams of intratympanic ABS group were found to have significantly deteriorated in some frequencies (p(0.05). The measurements of the other groups revealed no significant differences (p>0.05). Hearing loss was not observed in systemic absorption group but, determined in intratympanic application group. Conclusion: Our findings may suggest that hearing loss may be either due to ototoxic side effect of ABS, prolonged mass effect of it, or because of inflammation. Further studies with longer follow up period and histopathological examinations are needed to answer these existing questions.Öğe Publication pattern of Turkish medical theses analysis of 22 625 medical theses completed in years 1980 2005(Turkiye Klinikleri Journal of Medical Sciences, 2011) Özgen, Ünsal; Eğri, Mücahit; Aktaş, Mümtaz; Sandıkkaya, Ayşe; Öztürk, Ömer Faruk; Can, Sermet; Özcan, AbdulcemalOb jec ti ve: The objective of this study was to determine the conversion rates of Turkish residency theses to scientific articles. Ma te ri al and Met hods: 22.625 residency theses written at 28 university hospitals, nine state hospitals and two military hospitals’ residency programmes and recorded at the web of National Thesis Center were searched through Web of Science in order to evaluate their publication pattern in SCI-expanded journals in 1980-2005. Re sults: The number of published thesis at SCI expanded journals was found to be 1397 (6.2%) with the median number of citations received per paper ranging from 0.3 to 5.0. Publication percentage was highest for theses written at military hospitals and lowest for those written at state hospitals. Conc lu si on: Percentage of published thesis in Turkey is lower when compared to the remaining European Countries. Therefore, we need alternative practices to use our manpower, time and financial resources more effectively. The first alternative is to put an end to the obligation to write thesis in order to complete residency training in some types of hospitals or to convert this obligation to an option. Another alternative is to establish a National Thesis Advisory Center and make it essential to get approval from this center in order to conduct a thesis project.Öğe Publication Pattern of Turkish Medical Theses: Analysis of 22.625 Medical Theses Completed in Years 1980-2005(Ortadogu Ad Pres & Publ Co, 2011) Ozgen, Unsal; Egri, Mucahit; Aktas, Mumtaz; Sandikkaya, Ayse; Ozturk, O.

Tayyar; Can, Sermet; Aydin, Nasuhi EnginHairy polyps are rare benign tumors that are derived from 2 germ layers: ectoderm and mesoderm. Although location in the head and neck area is rare, the soft palate as the site of origin is even more unusual. The clinical presentation depends on the polyp's location and size. These masses can commonly cause respiratory and feeding difficulties. We present a case of a soft palate hairy polyp causing respiratory and feeding difficulties in a 6-month-old female infant and review the literature. (C) 2010 Elsevier Inc. All rights reserved.
