Öğe Anatomical Examination of the Foramens of the Middle Cranial Fossa(SOC CHILENA ANATOMIA, 2014) Unver Dogan, Nadire; Fazliogullari, Zeliha; Uysal, Ismihan Ilknur; Seker, Muzaffer; Karabulut, Ahmet KaganThree foramina can be identified in the greater wing of the sphenoid bone: The foramen rotundum (FR), foramen ovale (FO) and foramen spinosum (FS). In addition, there may be another foramen called foramen ovale accessorium or foramen vesalius (FV) which connects the middle cranial fossa to the fossa pterygoidea (pterygoid fossa). It is described as an opening with smooth walls in front and medial to foramen ovale which leads to an oblique channel directed towards the fossa pterygoidea. FV was present between FO and FR in 14 (31.8%) of 44 dry and 6 (33.3%) of 18 cadaver skullbase sides (total 20 (32.3%) of 62). The diameter values of foramens on both the right and the left side were observed to be almost symmetrical. FR's distance from the midline on the left side was greater than the right side. Also, the distance between FO and the petrous apex and the distance between FS and the petrous apex were greater on the left side. On the right side the distance between FO and FR, and the distance between FO and FS were greater. Also, the distance between FR and the petrous apex was greater on the right side. Anatomical variations in appearance size and distance of FR, FO, FS and FV are of great surgical importance. In conclusion, we can infer that the information provided with this study can help the neurosurgeon and anatomist to increase the knowledge about anatomy of middle cranial fossa.Öğe Clinical Significance of Maxillary Artery and its Branches: A Cadaver Study and Review of the Literature(SOC CHILENA ANATOMIA, 2011) Uysal, Ismihan Ilknur; Buyukmumcu, Mustafa; Unver Dogan, Nadire; Seker, Muzaffer; Ziylan, TanerThe aim of this study was to investigate the anatomy of the maxillary artery (MA) and its branches. Fourteen sides of Turkish adult cadavers were dissected. The specimens were classified according to the relation between MA and the lateral pterygoid. After the removal of the lateral pterygoid, parts and branches of MA were exposed. We classified the branching patterns of MA in the pterygopalatine fossa. The calibers and lengths of the arteries, and the distance between the zygomatic arch and MA, and between the infratemporal crest and MA were measured. The MA was found superficial to the lateral pterygoid in 57.2%. The inferior alveolar artery (IA) was arisen from MA before the middle meningeal artery (MM) in 35.7%, after MM in 35.7%. The IA and MM were arisen from the same area of MA in 14.3 %. In other two cases IA was arisen from the beginning of MA (14.3%). According to the contours of third portion of MA, we classified "Y" type (50%), "intermediate-T" type (14.3%), and "M" type (35.7%). This reinvestigation of the clinical anatomy of MA may provide useful information to the head and neck surgeons, dentists, neurosurgeons and radiologists related with this region.Öğe Developmental variations and clinical importance of the fetal thyroid gland - A morphometric study(SAUDI MED J, 2007) Cicekcibasi, Aynur E.; Salbacak, Ahmet; Seker, Muzaffer; Ziylan, Taner; Tuncer, Isik; Buyukmumcu, MustafaObjectives: To investigate the morphologic structures and developmental anomalies of the thyroid gland in human fetuses. Methods: This study performed in the Department of Anatomy, Meram Faculty of Medicine between February and April in 2002. Fetuses were obtained from the Gynecology Department of the Meram Faculty of Medicine, Selcuk University, and Dr. Faruk Sukan Maternity Hospital (Konya, Turkey). Sixty spontaneously aborted fetuses (30 boys and 30 girls) between the ages of 13.5th and 32.5th weeks, which had no detectable anomalies, were evaluated. The gland was dissected under the microscope. The location of the gland was determined according to the tracheal ring levels and laryngeal cartilage levels. The length, width and thickness of both lobes and isthmus of the gland were measured and then, the developmental anomalies were Me obtained data were statistically analyzed by Least Squares noted. in variant analysis. Results: Although there was no significant difference regarding to the gender for all parameters except in width of the right lobe (P<0.05), difference in the length and width of lobes and the length of isthmus between trimesters was significant (P<0.05). All measured parameters were increasing with advancing gestational age. Tbe pyramidal lobe was observed in 18.3% of the cases. Conclusion: Normal dimensions and developmental anomalies of the fetal thyroid, which was shown in this study, may provide useful information for the prenatal diagnosis and in-utero treatment of thyroid dysfunctions.Öğe Histological and histomorphometric studies on the cerebellar cortex and silver stained nucleolus organizer regions of Purkinje neurons in chronic morphine-treated rats(UNIV ZAGREB VET FACULTY, 2018) Celik, Ilhami; Seker, Muzaffer; Salbacak, AhmetThe effects of chronic morphine administration on the rat cerebellum and silver stained nucleolus organizer regions in Purkinje cells were investigated by means of histological, histochemical and histometrical techniques. Thirty-two young (30-32 days of age) Wistar rats (equal numbers of both genders) were randomly divided into 2 groups, as control and morphine-treated, each having equal numbers of both genders, a total of 16 animals. The control animals were injected subcutaneously with 1mL/kg physiological saline, and the morphine-treated rats received 5 mg/kg morphine hydrochloride subcutaneously at daily intervals for 30 days. The thickness of the molecular and granular layers of the cerebellum, the diameters of the nuclei and nucleoli of cerebellar Purkinje neurones, and the number and size of the silver staining nucleolus organizer regions of the Purkinje cell nuclei were determined histomorphometrically. The morphine administration caused slight histological changes in the cerebellum. The molecular layer thickness of the cerebellum was significantly (P<0.05) reduced, and the decrease was mainly in the male animals. In contrast, the layer thickened insignificantly in the morphine-treated females. The granular layer thickened slightly but insignificantly in both genders of the morphinetreated group. The Purkinje cell count significantly decreased with morphine treatment. Nucleus size did not change with morphine treatment. However, morphine-treated animals had smaller nucleoli. It was concluded that morphine treatment caused significant histomorphological changes in the cerebellar cortex in a sexually dimorphic manner.Öğe Knowledge of new entrant medical students about medical errors in Selcuk University: An educational perspective(ORTADOGU AD PRES & PUBL CO, 2008) Karaoglu, Nazan; Seker, Muzaffer; Kara, Fatih; Okka, BerrinObjective: In the recent years, medical errors and patient safety have held a great emphasis especially since the report of the Institute of Medicine was published in 1999. Medical students witness and sometimes are involved in unsafe Situations, errors, adverse events etc. The first years of medical education is a chance to teach students medical errors and patient safety. The aim of this cross-sectional descriptive study was to asses the knowledge of medical students on medical errors and the effect of education on knowledge. Material and Methods: This study was conducted in Meram Medical Faculty of Selcuk University. We prepared a questionnaire including the definition of, attitudes towards and reporting of medical errors according to the literature on this subject. This questionnaire was given to first and second year students by the authors during a lesson in November 2007. Results: Study population consisted of 119 male and 123 female students. In the error definition questions although the first year students received 11.24 +/- 4.64 points, second year students had 9.34 +/- 5.38 points. Females had 11.30 +/- 4.67 points and males had 9.14 +/- 5.36 points. The most unrecognized medical error was on prophylaxis (54.4% in the first year, 60.5% in the second year). Misdiagnosis was the most recognized error in both groups. Conclusion: We suggest that patient safety culture can be established properly, easily and correctly if students are equipped with the required knowledge on medical errors starting from the first years of medical education. This may then improve the quality of medical staffs and institutes.Öğe Looking for winds of change with a PBL scenario about communication and empathy(DRUNPP-SARAJEVO, 2011) Karaoglu, Nazan; Seker, MuzafferAim: Good communication is associated with improved health of patients and empathy is a cornerstone of physician-patient communication. Medical education seems to be ineffective in helping students to maintain or increase their empathy. Some of benefits of Problem Based Learning (PBL) are about communication and interpersonal skills. This study aims to determine the effect of a PBL scenario on attitudes towards communication skills, the empathic tendency and the empathic skills of 1st year medical students. Materials and Methods: Attitude changes after the PBL scenario were evaluated via Communication Skills Attitude Scale (CSAS), Empathic Tendency Scale (ETS) and Empathic Skill Scale (ESS). Results: The positive attitude change was significant for male students (p=0.03). The means of ETS scores were 68.42 +/- 8.28 and 69.18 +/- 8.53 (p=0.36) and the means of ESS scores were 131.16 +/- 17.28 and 133.30 +/- 18.35 in the pre and post-tests, respectively (p=0.22). The ESS scores of male students both in pre and post tests were significantly higher than female students (p=0.00). A significant negative correlation between NAS and ETS and a positive correlation between PAS and ETS in both tests were determined. Conclusion: This scenario significantly increased positive attitudes (PAS) of students towards communication skills. There was also an increase in empathic tendency and skills.Öğe The Mandibular Landmarks about the Facial Artery and Vein with Multidetector Computed Tomography Angiography (MDCTA): an Anatomical and Radiological Morphometric Study(SOC CHILENA ANATOMIA, 2012) Cicekcibasi, Aynur Emine; Yilmaz, Mehmet Tugrul; Kiresi, Demet; Seker, MuzafferThe aim of this study was to investigate the course of the facial vessels according to several mandibular landmarks in living individuals using multidetector computed tomography angiography (MDCTA) to determine these related to sex and side. This study was conducted in the Radiology Department, Meram Faculty of Medicine, Necmettin Erbakan University (Konya, Turkey). In total, sixty faces from 30 specimens (15 males and 15 females) with symptoms and signs of vascular disease were evaluated for the facial vessels by MDCTA scan. The facial vessel parameters were measured according to the reference points (mandibular angle, mental protuberance, mental foramen and facial midline). The distance from the point at which the facial artery first appears in the lower margin of the mandible to the mandibular angle for right and left facial artery were observed as 3.53 +/- 0.66 cm and 3.31 +/- 0.73 cm in males, respectively. These distances were determined as 2.91 +/- 0.52 cm and 3.35 +/- 0.48 cm in females. MDCTA is a new, powerful, safe and noninvasive test to demonstrate the vasculature of the head. Bony structures and neighboring vessel morphology can be evaluated by this technique in cases of trauma with suspected vessel injuries and when considering patient selection for flap surgery.Öğe The reasons for being a doctor and the future expectations(DRUNPP-SARAJEVO, 2010) Karaoglu, Nazan; Ongel, Kurtulus; Seker, MuzafferThe aim of this study was to find out the specific features of medical students in respect to medical career selection, factors effecting this decision and future expectations. With a questionnaire first term medical faculty students of Selcuk University of two academic years were compared. Objectives: Deciding to be medical doctor is a very difficult decision which is effected by many factors. We aimed to find out the specific features of students, reasons for selecting medical faculty, factors effecting this decision and future expectations of medical students. Study design: In this cross-sectional study a questionnaire of was applied to the first term medical faculty students of Selcuk University in two academic years. Results: Participation rate was 80.48% (132/164) for 2007-2008 and 81.41% (184/226) for 2009-2010. Mean age was 18.93 +/- 1.19 years. For most of them (77.1%) medical career was among the first three choices in the career exam. Above half (59.0%) got information about working conditions of medical career before decision making and 89.2% stated that they would chose this career again if they had a chance to make a change. While mostly noted reason for selecting medical career was individual factors (74.7%), economic factors were the second reason noted (69.6%). We found statistical difference between two academic years in respect to statue and economic expectations after graduation besides institutional expectations in all categories (p<0.05). Conclusion: The results of this study showed that besides personal wish economic factors are very important in medical career selection which we must think about.Öğe The role of desire and expectations from medicine in students' well-being(TAYLOR & FRANCIS LTD, 2009) Karaoglu, Nazan; Seker, Muzaffer[Abstract not Available]
