Publication Metadata only Corticospinal tract involvement in a patient with 3-HMG coenzyme A lyase deficiency(ELSEVIER SCIENCE INC, 2006) EKİNCİ, GAZANFER; Yylmaz, Yuksel; Ozdemir, Nihal; Ekinci, Gazanfer; Baykal, Tolunay; Kocaman, Canan3-Hydroxy-3-methylglutaryl coenzyme A lyase deficiency, an inborn error of ketone body synthesis and leucine degradation, is a rare disorder. There are few reports demonstrating clinical and neuroradiologic findings of this condition. This report describes a 3.5-year-old previously healthy male who was admitted with complex partial seizures and was diagnosed as having 3-hydroxy-3-methylglutaryl coenzyme A lyase deficiency. The patient's previous medical history was unremarkable. His development and neurologic examination were normal. Cranial magnetic resonance imaging indicated prominent corticospinal tract and pontine involvement with focal cerebral white matter changes which have not been described in the literature before.

A study of 3.0-Tesla lumbar MRI comparing skeletal, neural, and vascular markers(ELSEVIER SCIENCE INC, 2014) TÜRELİ, DERYA; Tureli, Derya; Ekinci, Gazanfer; Baltacioglu, FeyyazPurpose: This study aimed to determine the reliability of the iliolumbar ligament (ILL), 12th costa, aortic bifurcation (AB), Tight renal artery (RRA), and conus medullaris (CM) for numbering of vertebral segments. Subjects and methods: Five hundred five patients underwent routine lumbar MRI examinations including a cervicothoracic sagittal scout and T1 and T2-weighted sagittal and axial turbo spin echo images. Images were evaluated by two radiologists separately. Results: The identifiability of ILL and 12th costa were 85.7% and 48.1%. AB, RRA, and CM were located more caudally in lumbarized S1 and more cranially in sacralized L5 cases. Conclusion: Landmarks suggested by previous studies are not reliable alternatives to cervicothoracic scout images due to wide ranges of distribution and inconsistencies in identification.

O., Ekinci G., Afsar N. E. Y., Cavdar S.Publication Metadata only Utility of Interobserver Agreement Statistics in Establishing Radiology Resident Learning Curves During Self-directed Radiologic Anatomy Training(ELSEVIER SCIENCE INC, 2015) BALTACIOĞLU, FEYYAZ; Tureli, Derya; Altas, Hilal; Cengic, Ismet; Ekinci, Gazanfer; Baltacioglu, FeyyazRationale and Objectives: The aim of the study was to ascertain the learning curves for the radiology residents when first introduced to an anatomic structure in magnetic resonance images (MRI) to which they have not been previously exposed to. Materials and Methods: The iliolumbar ligament is a good marker for testing learning curves of radiology residents because the ligament is not part of a routine lumbar MRI reporting and has high variability in detection. Four radiologists, three residents without previous training and one mentor, studied standard axial T1- and T2-weighted images of routine lumbar MRI examinations. Radiologists had to define iliolumbar ligament while blinded to each other's findings. Interobserver agreement analyses, namely Cohen and Fleiss kappa statistics, were performed for groups of 20 cases to evaluate the self-learning curve of radiology residents. Results: Mean kappa values of resident-mentor pairs were 0.431, 0.608, 0.604, 0.826, and 0.963 in the analysis of successive groups (P <.001). The results indicate that the concordance between the experienced and inexperienced radiologists started as weak (kappa <0.5) and gradually became very acceptable (kappa >0.8). Therefore, a junior radiology resident can obtain enough experience in identifying a rather ambiguous anatomic structure in routine MRI after a brief instruction of a few minutes by a mentor and studying approximately 80 cases by oneself. Conclusions: Implementing this methodology will help radiology educators obtain more concrete ideas on the optimal time and effort required for supported self-directed visual learning processes in resident education.Publication Open Access Atypical presentations of eosinophilic fasciitis(MEDKNOW PUBLICATIONS & MEDIA PVT LTD, 2016) SALMAN, ANDAÇ; Ergun, Tulin; Seckin, Dilek; Salman, Andac; Ocak, Esra Sarac; Yucelten, Ayse Deniz; Direskeneli, Haner; Demirkesen, Cuyan; Ekinci, Gazanfer; Bayik, MahmutEosinophilic fasciitis is an uncommon connective tissue disease that may mimic and overlap with other sclerosing disorders such as morphea and lichen sclerosus. Herein, we report four patients (two men and two women, aged 16-64 yeas) with eosinophilic fasciitis. There was overlap with both morphea and lichen sclerosus in 2 patients and with morphoea alone in 1 patient. Magnetic resonance imaging (MRI) was used for diagnosis in three patients and for assessing treatment response in one patient. Eosinophilic fasciitis may co-exist with morhoea and lichen sclerosus. In view of the overlapping clinical and histopathological features of these disorders, MRI may be helful in delineating the conditions by detecting involvement of fascia.Publication Metadata only Progressive dysarthria and dysphagia in an otherwise healthy girl(PERGAMON-ELSEVIER SCIENCE LTD, 2013) EKİNCİ, GAZANFER; Koytak, Pinar Kahraman; Alibas, Hande; Ekinci, Gazanfer; Uluc, KayihanPublication Metadata only The effectiveness of ultrasonography and ultrasonographic elastography in the diagnosis of carpal tunnel syndrome and evaluation of treatment response after steroid injection(ELSEVIER IRELAND LTD, 2018) EKİNCİ, GAZANFER; Asadov, Ruslan; Erdal, Ayse; Bugdayci, Onur; Gunduz, Osman Hakan; Ekinci, GazanferPurpose: To evaluate if there is a place for ultrasonography (US) and ultrasonographic elastography (UE) in the diagnosis and follow up of carpal tunnel syndrome treatment. Materials and methods: The study was performed on 25 patients (study group) and 17 healthy volunteers (control group). Measured US and UE criteria were median nerve area (MNA), proximal median nerve area (pMNA), difference between MNA and pMNA (dMNA) and strain values of carpal tunnel content (CTC) and median nerve (MN). Patients in the study group were also evaluated using the Boston questionnaire, Visual Analogue Scale (VAS) and nerve conduction studies. Thirty-three wrists in 23 patients received steroid injections on the same day. Patients were re-evaluated 6 weeks after steroid injection. To establish a cut off value for MNA, ROC Curve analysis was used. Results: Mean MNA and dMNA values in the control group were significantly lower than in the study group (7.33 +/- 1.31 vs. 15.44 +/- 5.10; p = < 0.05 and 1.58 +/- 0.75 vs. 8.91 +/- 4.93; p = 0.00 respectively). Median nerve and CTC strain indices were significantly higher in the control group (p = 0.00 and p = 0.036). Decrease in MNA and dMNA values after treatment was meaningful (p = 0.00). While there was no significant change in MN elasticity, mean CTC strain index of the study group (4.680 +/- 1.664) decreased significantly after treatment (3.621 +/- 1.054 p = 0.002). This decrease in the CTC index was more pronounced in patients who benefited from treatment (p = 0.001). Conclusion: US and UE can be useful in the diagnosis of CTS and its response to treatment, if used together with clinical and electroneurophysiological tests.Publication Metadata only Point- and frequency-specific response of the testicular artery to abdominal electroacupuncture in humans(ELSEVIER SCIENCE INC, 2008) EKİNCİ, GAZANFER; Cakmak, Yusuf Ozgur; Akpinar, Ihsan Nuri; Ekinci, Gazanfer; Bekiroglu, NuralObjective: To clarify the role of the abdominal acupuncture points and the frequency of short-term electroacupuncture (EA) stimulation on testicular blood flow (TBF) in humans. Design: A prospective, randomized study. Setting: University hospital, Department of Radiology, ultrasound unit. Patient(s): Eighty healthy male volunteers were randomly allocated to three groups in stage one and to a single group in stage two. In the first stage of the study, the abdominal acupuncture points ST-29 (guilai) were stimulated using simple needle insertion, 2 Hz burst EA or 10 Hz EA. in three different groups. In the second stage of the study, abdominal acupuncture points ST-25 (tianshu) were stimulated with the frequency found to be more effective in stage one. Stimulation was for 5 minutes in each group. Intervention(S): Electroacupuncture and Doppler flowmeter. Main Outcome Measure(S): Four groups were compared for volume flow and other related parameters of TBF. Result(S): The 10-Hz EA stimulation of ST-29 (guilai) increased TBF, but simple needle insertion and 2-Hz burst stimulation did not. The 10-Hz EA stimulation of ST-25 (tianshu) did not result in significant changes in TBF. Conclusion(s): For the first time point- and frequency-specific effects of abdominal EA on TBF are shown in humans. Further investigation is required to ascertain whether these findings may be helpful in the clinical treatment of infertile men. (Fertil Steril(R) 2008;90:1732-8.
