Nonodontogenic mandibular lesions: differentiation based on CT attenuation

Mandibular lesions are classified as odontogenic and nonodontogenic based on the cell of origin. Odontogenic lesions are frequently encountered at head and neck imaging. However, several nonodontogenic pathologies may also involve mandible and present further diagnostic dilemma. Awareness of the imaging features of nonodontogenic lesions is crucial in order to guide clinicians in proper patient management. Computed tomography (CT) may provide key information to narrow diagnostic considerations. Nonodontogenic mandibular lesions may have lytic, sclerotic, ground-glass, or mixed lytic and sclerotic appearances on CT. In this article, our aim is to present various nonodontogenic lesions of the mandible by categorizing them according to their attenuations on CT

Yükseköğretim kurumunda iç paydaş memnuniyet analizi: Pamukkale Üniversitesi örneği

Quality development studies in higher education institutions become more of an issue in recent years regarding competition globally. The studies in the universities in Turkey are carried out within the scope of the legislation determined by the Council of Higher Education. In this context, universities are held responsible of setting up the internal quality assurance system and external quality assurance system and as well as internal and external evaluation processes. In this study, the internal shareholders (academic staff, administrative staff, and students) satisfaction surveys conducted in the context of the internal evaluation process in a higher education institution and designed according to the Guidelines for Preparing the Institutional Internal Evaluation Report of the Higher Education Council were analyzed using Structural Equation Model. Factors affecting the satisfaction of the shareholders were determined according to the obtained data, and it was determined that the survey was not appropriate for the questioning of the students even though the same and high relation was observed between the subheadings in the questionnaire prepared for the students

Radiotherapy Induced Changes of Masticatory Muscles and Parotid Glands on MRI in Patients with Nasopharyngeal Carcinoma

Objective: The aim of this study was to identify radiotherapy (RT) induced changes of masticatory muscles and parotid glands on magnetic resonance imaging (MRI) in patients with nasopharyngeal carcinoma (NPC). Patients and Methods: Thirty-one patients treated with RT for NPC between 2009-2016 in our instution were included in the study. MRI examinations performed before and after RT were reviewed retrospectively. Transverse diameters and signal intensities of masticatory muscles and parotid glands were evaluated on T2 weighted axial MR images. Normal (hypointense) signal was scored as 0, mild hyperintensity as 1 and severe hyperintensity as 2. Results:The mean interval between pre-RT MRI and last control MRI was 44 months (12-84 months). Reductions of transverse diameters were; right masseter (RM):2.32mm (15%), left masseter (LM):2.42mm (15.4%), right medial pterygoid (RMP):1.26mm (8.7%), left medial pterygoid (LMP):1.71mm (12%), right lateral pterygoid (RLP):1.35mm (9.6%), left lateral pterygoid (LLP):1.32mm (9.4%), right parotid gland (RP):8.22mm (26%), left parotid gland (LP):8.87mm (28%). T2 signal changes were; RM: mild 8 cases (26%), LM: mild 5 cases (16%), RMP: mild 5 cases (16%), severe 1 case (3.5%), LMP: mild 4 cases (13%), severe 2 cases (6.5%), RLP and LLP: mild 8 cases (26%), severe 3 cases (9.7%), RP: mild 10 cases (32%), severe 18 cases (58%), LP: mild 10 cases (32%), severe 17 cases (55%). Conclusion: Volume loss and hyperintensity were mostly seen in parotid glands. Masseter was the muscle with highest rate of volume loss and lateral pyterygoid showed the highest rate of hyperintensity in masticatory muscles

Recurrent chronic subdural hematoma: Report of 13 cases

Chronic subdural hematoma is a frequent type of hemorrhage, which terminates with mortality if not diagnosed and treated early. The aim of this clinical study is to evaluate the patients with unilateral and bilateral recurrent chronic subdural hematoma
