Acute Mountain Sickness Occurring With Corpus Callosum, Globus Pallidus and Cerebellar Peduncle Involvement: Mri Findings
(2010) Avcu, S.; Arslan, H.; Göktaş, U.; Bulut, M.D.; Ünal, Ö.
Acute mountain sickness (AMS) is a pathological reaction, occurring as a result of failure to adapt to altitude. The main symptoms reported are headache, nausea, vomiting and fatigue. However, high altitude cerebral and pulmonary edema, occurring in AMS, cause potentially fatal consequences. In our 31-year-old case, who is the group leader and activity organizer among nine mountaineers, who climbed Mt. Aĝri{dotless} for winter climbing, nausea, vomiting, unconsciousness, lack of appetite and severe headache have occurred in connection with high altitude at 4200 m. Brain MRI of the patient revealed wide-spread hyperintense lesions at subcortical white matter, corpus callosum, globus pallidi, and bilateral cerebellar peduncles on T2 and FLAIR series. The patient was referred to anesthesia-intensive care unit of our hospital. Since the appearances are demonstrative, MRI findings are presented. © 2010 Elsevier Ireland Ltd.
Anatomic Variations of the Paranasal Sinuses: Ct Examination for Endoscopic Sinus Surgery
(1999) Arslan, H.; Aydinlioglu, A.; Bozkurt, M.; Egeli, E.
Chronic rhinosinusitis endoscopic surgery requires an accurate evaluation of diseases and paranasal sinus anatomic variations. This study aims to show the main anatomical variations in the ostiomeatal complex and paranasal sinuses which are usually depicted by computed tomography (CT). CT scans obtained 2 mm thickness in axial and coronal plane from a series of 200 patients with chronic sinusitis were examined to determine the prevalence of anatomic variants. Anatomical variations determined were supraorbital recess in 6%, concha bullosa in 30%, sphenomaxillary plate in 17%, infra-orbital ethmoid cells (Haller's cells) in 6%, spheno-ethmoid cells (Onodi's cells) in 12%, pneumatization of the anterior clinoid process in 6%, carotid artery bulging into the sphenoid sinus in 8%, pneumatization of the uncinate process in 2%, paradoxical curvature of the middle turbinate in 3% and septal deviation in 36%. Level difference between the ethmoid roof and nasal vault was an average of 8 mm in right side and 9.5 mm in left side. Awareness of these different variations will help the rhinologic surgeon in his orientation during endoscopic surgical procedures.
Anterior Stabilization Application With Odontoid Screw in a Patient With Type 2 Odontoid Fracture a Case Report
(Yuzuncu Yil Universitesi Tip Fakultesi, 2022) Taş, A.; Aycan, A.; Arabaci, O.; Yokuş, A.; Arslan, H.
The treatment of type II odontoid fractures has been discussed for many years. Due to the complex anatomy of the craniocervical junction, many-questions are encountered in the diagnosis and treatment of such fractures. However, in centers without Neuro-navigation and O-arm, free hand technique still remains a viable option for the surgical treatment of such cases. Although there is no neuronavigation and O-arm in our center, we will present our case of type II odontoid screw placement with free hand technique that we successfully applied in our elderly patient with a Type II fracture. © 2022, Yuzuncu Yil Universitesi Tip Fakultesi.

Colloid Cyst Presenting With Acute Hydrocephalus in an Adult Patient: Case Report and Review of Literature
(Yuzuncu Yil Universitesi Tip Fakultesi, 2018) Aycan, A.; Gülşen, İ.; Arslan, M.; Kuyumcu, F.; Akyol, M.E.; Arslan, H.
Colloid cysts (CC) are rare cystic lesions with a wide clinical spectrum including the asymptomatic cysts that are coincidentally diagnosed and the cysts leading to sudden death. The symptoms in CC are usually caused by obstructive hydrocephalus. The most common symptom for CC is headache. CC rarely cause intracranial herniation and death. In this study, we aimed to present our experience in the diagnostic and treatment process of a 57-year-old male patient with CC who presented to the emergency service with sudden severe headache, vomiting and confusion. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi.

Common Coeliacomesenteric Trunk: a Computed Tomography Radiological Study
(Via Medica, 2018) Ozgokce, M.; Ayyildiz, V. A.; Ogul, H.; Arslan, H.; Batur, A.; Yavuz, A.; Yuce, D.
Background: There is an increasing trend for administration of invasive radiological interventions, laparoscopic surgery, and transplantation procedures in recent years, and determining the vascular variations prior to these procedures is crucially important. Coeliacomesenteric trunk (CMT) is among these variations. This study aimed to retrospectively evaluate this rare anomaly by computed tomography (CT). Materials and methods: A total of 1000 CT angiography images were analysed retrospectively, and the patients with mesenteric and coeliac arteries arising from the abdominal aorta with a single root were identified. The level that CMT arose, and its branching patterns were determined individually for all patients. Results: Ten patients (6 males and 4 females) with a mean age of 50.2 years (17-87 years) had CMT in CT images. Conclusions: The knowledge of variations in the CMT prior to vascular or laparoscopic interventions will contribute to early intervention in case of a complication, or to avoid from a potential damage.
Contribution of Sonoelastography in the Differentiation of Benign and Malignant Breast Masses: a Comparative Analysis on Sonographic Birads Classification
(Yuzuncu Yil Universitesi Tip Fakultesi, 2017) Arslan, H.; Akdemir, Z.; Yavuz, A.; İslamoglu, N.; Çelik, S.; Özgökçe, M.; Tolunay, H.E.
In this study, we aimed to investigate the effectivity of ultrasonographic elastography in the differentiation of benign and malignant lesions detected on B-mode ultrasonography. The retrospective study included 133 consecutive patients who underwent B-mode USG followed by elastography between January 2013 and December 2015. The lesions were scored by using B-mode USG with breast imaging-report and data systems (BIRADS) and then sonoelastographic color-coded maps were obtained by elastography in a single session. Sonoelastographic scoring was achieved with a 5-point scoring system. Elasticity scores and strain ratio (SR) values were compared with histopathological findings. The 133 patients included 132 (99.2%) women and 1 (0.8%) man. Mean age was 40.45±14.8 years. The lesions were mostly localized in the left breast (n=70, 52.3% vs. n=63, 47.7%). Depending on the pathological findings, 94 (71.2%) lesions were classified as benign and 39 (28.8%) as malignant. Mean SR value was 4.419±1.43, with 5.5 in malignant lesions and 4.3 in benign lesions. At the cut-off value of 4.95 for SR, the sensitivity and specificity of USG in elastographic examination were 81.6% and 78.7%, respectively. A significant correlation was found between the SR value and the BIRADS score calculated on USG (rho=0.86; two-tailed; p<0.001). Similarly, a significant correlation was found between the SR value and the elasticity score (rho=0.88; two-tailed; p<0.001). In conclusion, the use of sonoelastographic examination following the USG examination with B-mode ultrasonography can be a complementary diagnostic method that increases the specificity of USG. Moreover, it can also reduce unnecessary biopsies in lesions with suspicious malignancy. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Could Bladder Wall Elastography Be Used as an Indicator for the Diagnosys of Bladder Outlet Obstruction by Benign Prostate Hyperplasia
(Yuzuncu Yil Universitesi Tip Fakultesi, 2020) Eryılmaz, R.; Aslan, R.; Arslan, H.; Demir, M.; Türkoğlu, S.; Araz, Ş.; Taken, K.
Benign prostatic hyperplasia (BPH) is one of the most common causes of bladder outlet obstruction in men. In this study we aimed to evaluate the elasticity of the bladder by Acoustic Radiation Force Impulse (ARFI) elastography in BPH patients. Fifty benign prostate patients were included in the study. After evaluation of patients in the outpatient clinic. A RFI elastography was performed with full bladder. Elastography was performed separately on the anterior, right and left walls of the bladder. Then the patient underwent uroflowmetry. The maximum flow rate and post-mix residual values in uroflowmetry were recorded. The mean age of the patients was 45.6 ± 3.77 The average of bladder anterior wall elasticity 3.39 ± 0.89, Bladder left wall elasticity 2,69 ± 0,82 and Bladder right wall elasticity was 3.69 ± 0.89.The mean prostate size 52.58 ± 24.16 The average of Qmax11.96 ± 4.85 The mean of PMR 77.8 ± 59.6 and mean of prostate elasticity was 2.97 ± 1.1 Urinary bladder wall elasticity with ARFI can be a diagnostic indicator for bladder outlet obstruction due to BPH. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi.

Functional and Radiological Impairment in Women Highly Exposed To Indoor Biomass Fuels
(2001) Özbay, B.; Uzun, K.; Arslan, H.; Zehir, I.
Objective: The aim of this study was to describe the lung function and the computed tomographic features in a selected group of non-smoking women with chronic obstructive pulmonary disease and biomass fuel exposure. Methodology: Thirty female patients currently exposed to biomass smoke were prospectively investigated for further evaluation using high resolution computed tomography (HRCT), pulmonary function tests and blood gas analysis. Results: The mean age was 59±11 years. The patients were exposed to biomass smoke for 37.4± 10 years. Pulmonary function tests revealed severe obstruction. The most common HRCT findings were increased lung volume or diffuse emphysema, thickening of interlobular septae, focal emphysematous areas, increased cardiothoracic ratio, and increased bronchovascular arborization. Conclusion: Biomass fuel has deleterious effects on pulmonary function and structure leading to obstructive and restrictive pathologies.
Intersection of the Rights To Freedom of Belief and Gender Equality in Turkey
(Brill Nijhoff, 2023) Yılmaz, Z.; Arslan, H.
Despite the efforts of the women’s movement in Turkey, gender equality as a norm has been abandoned in state policies due to the rise of neoliberal authoritarianism. Our study aims to take a snapshot of religious services access and gender equality while stressing the parallel norms by focusing on justice, equality and the prohibition of discrimination. Further, since ensuring freedom of religion or belief and gender equality is the duty of the state, our research exposes the legal and institutional framework regulating the intersection of these two fundamental human rights areas and Turkey’s related policies and practices. In doing so, the study delves into the state’s adherence to international human rights treaties and elaborates on women’s positioning in the organization of religious services, as well as shedding light on human rights protections and observed violations of those rights within the spheres of family law and religious education. © 2023 Brill Nijhoff.

Measurement of Postoperative Liver Volume Changes in Patients With Gastric Cancer by Computed Tomography
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Yokuş, A.; Arslan, H.; Akdemir, Z.; Akbudak, İ.; Almalı, N.; Kotan, Ç.; Doğan, E.
One of the most prevalent cancer worldwide is gastric cancer. Surgical treatment is the only curative method. In this study, we aimed to investigate the changes in liver volume before and after open gastrectomy in patients diagnosed with gastric cancer. We retrospectively analyzed the computed tomography scans of 70 patients who underwent gastric cancer surgery between June 2013 and December 2020. Preoperative and postoperative total liver volume, the volume of segments II-III, and segment IV were measured. The data obtained from volume measurements were compared statistically. Of the 70 subjects included in the study, 48 were male and 22 were female, with an average age of 64.2±11.8 years. In the postoperative phase, the volume of segments II-III and IV dropped significantly compared to the preoperative period (p=0.001 for both). Total liver volume exhibited a mild decrease in the postoperative period, but the total volume loss was not statistically significant (p=0.744). In this study, we detected significant volume loss in segments II-III and segment IV after open gastrectomy. However, the total liver volume reduction was less. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Misplacements of Central Venous Catheters: Internal Jugular Versus Subclavian Access in Critical Care Patients
(TIP ARASTIRMALARI DERNEGI, 2007) Tekin, M.; Özbay, B.; Kati, I.; Arslan, H.
Aim; In central venous catheterization (CVC), misplacement is not a rare complication since this is a blinded procedure. The aim of this study was to compare the misplacement risks of the access of internal jugular vein with that of subclavian vein catheterizations. Methods;The records of a total of 1092 patients in whom central venous catheters were placed between 2002 and 2006 in Anesthesiology Intensive Care Unit and the location of the tips was confirmed radiologically were retrospectively evaluated. Neck and infraclavicular region were cleaned by antiseptic solution after routine monitorization. CVC were easily inserted with Seldinger's technique after blood aspiration through internal jugular vein or subclavian vein. Results; In adult patients, six internal jugular catheter misplacements were seen (0.80%); among them five were kinking and one was intrapleural location of the catheter tip. Six subclavian misplacements (2.02 %) were detected, five of them were located in contralateral subclavian vein, and one was located in ipsilateral internal jugular vein. In children, two subclavian misplacements were seen as crossing to contraleteral subclavian vein, and there were no internal jugular misplacement. There was no statistically difference for misplacement between the access sites (in adult p= 0.110, in children p=0.501). Conclusion; We have concluded that experience of operator should be taken into account for choice of catheterization site.
Multiple Sclerosis: Does the Apparent Diffusion Coefficient Have a Diagnostic Efficiency in Active-Inactive Demyelinating Plaques
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Arslan, H.; Akıncı, M.B.
In multiple sclerosis (MS) patients, in the evaluation of active and inactive plaques, the contribution of Apparent Diffusion Coefficient (ADC) measurements to the diagnosis was investigated. A total of 88 patients, 66 women and 22 men, were examined in this study. The patients’ ages ranged from 19 to 53; the median age was 30.5 ±8.1. ADC measurements were taken of every plaque from active and inactive plaques using co ntrast enhancement (CE) Magnetic Resonance İmaging MRI. ADC measurements were considered active (92) or inactive (230) in accordance to their contrast enhancement, and specificity and sensitivity values were checked. We examined and comparison the descriptive statistics results of MS plaques in relation to the active and inactive groups in terms of ADC measurement values. Accordingly, the averages for the active and inactive groups, respectively, were found to be 1.011 and 1.245, and the difference was statistically significant be tween these two averages (p<0.01). Accordingly, our study shows that ADC measurements are higher in the inactive group. ADC measurements can be a useful imaging modality in the differentiation of MS plaques in diffusion-weighted imaging. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Our Experience in Eight Cases With Urinary Hydatid Disease: a Series of 372 Cases Held in Nine Different Clinics
(Wiley, 2006) Yilmaz, Y.; Kosem, M.; Ceylan, K.; Koseoglu, B.; Yalcinkaya, I.; Arslan, H.; Soylemez, O.
Objectives: Hydatid disease, a parasitic infestation caused by the larval stage of the cestode Echinococcus granulosus, is diagnosed commonly in the east and south-east regions of Turkey. The aim of this study is to emphasize the relatively frequent occurrences of echinococcosis in our region, and to discuss therapeutic options and treatment results according to current literature. Methods: A retrospective 10-year review of nine different clinics' records of the Research Hospital of the Medical School of Yuzuncu Yil University revealed 372 hydatid disease cases that were localized in various organs and treated surgically (271 cases) or drained percutaneously (99 cases). Hydatid disease was diagnosed by ultrasonography (US) and computed tomography scans (CT) and confirmed histopathologically. Results: The involved organ was lung in 203 cases (131 adults, 72 children), liver in 150, spleen in 9, brain in 2, kidneys in 7 cases and the retrovesical area in 1 case. The urogenital system is involved at a rate of 2.15%. Two hundred and seventy-one cases were treated surgically and 99 percutaneously. Two cases with renal hydatid cyst refused the surgical procedure (one had a solitary kidney with hydatid cyst). Albendazole was administered to 192 patients; 93 patients had open surgical procedure and 99 patients underwent percutaneous procedure. Cysts were excised totally in the open surgical procedure; however, involved kidneys were removed totally (four cases) except one. Cystectomy and omentoplasty was performed in one case. Complications were as follows: in six cases, cystic material was spilled into the bronchial cavity during the dissection and a renal hydatid cyst ruptured and spilled retroperitoneally. Conclusion: Hydatid disease is a serious health problem in Turkey. The mainly affected organs are liver and lung. It can be treated surgical or by percutaneous aspiration.
Pigmented Villonodular Synovitis Within Baker's Cyst: the Role of Mr-Arthrography
(Elsevier BV, 2003) Harman, M.; Arslan, H.; Doǧan, A.; Özen, S.; Ipeksoy, Ü.
We report a case of pigmented villonodular synovitis (PVNS) within Baker's cyst in a 55-year-old man who admitted to hospital with palpable popliteal mass. The mass was examined with ultrasonography (US), magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA). MRA was the best modality in the demonstration of the connection of the lesion with the joint space. In this study, we emphasized on the importance of the MRA in the PVNS within Baker's cyst. To the best our knowledge, this is the first report that illustrates the MRA characteristics of a PVNS within Baker's cyst. © 2002 Elsevier Science Ireland Ltd. All rights reserved.
Post-Traumatic Omental Herniation Into Pleural Space: Radiologic Features
(Elsevier BV, 2003) Harman, M.; Arslan, H.; Ayakta, H.; Odabasi, H.
A 43-year-old male with history of trauma was admitted to our clinic for the further evaluation of a blunted left costophrenic angle on chest roentgenograms. Computed tomographic (CT) scans demonstrated a crescent, fat-dense, extra-pleural mass on the left lateral hemi-thorax. Vertical funicular densities consistent with blood vessels were identified in this extra-pleural lesion on enhanced CT scans. T1-weighted axial and coronal magnetic resonance images (MRI) disclosed that the omentum ran continuously from the abdominal cavity into thoracic cavity a long left lateral hemi-thorax through a defect in the diaphragm. Surgical exploration revealed the laceration of left diaphragm and left parietal pleura. The omentum was herniated into the left pleural space through small diaphragmatic defect. We report X-ray, CT and MRI features of post-traumatic omental herniation into the pleural space that, to our knowledge it has not yet been reported so far.
Power Doppler Sonography in the Diagnosis of Graves’ Disease
(2000) Arslan, H.; Unal, O.; Algün, E.; Harman, M.; Sakarya, M.E.
In addition to color and pulsed Doppler sonography findings, we aimed to describe power Doppler sonography findings in Graves’ disease in this study. Twenty-three patients with Graves' disease were imaged with gray-scale, color and power Doppler sonography. Twenty normal volunteers were examined by the same equipment and the same technique as a control group. A subjective grading system was used to categorize the vascularization in pulsed Doppler sonography images from normal to markedly increased vascularization. Power Doppler sonography exhibited diffuse hypervascularity in the thyroid gland in all patients. The flow was covering about all the parenchyma. Four patients showed mild, 12 patients moderate and seven patients marked vascularity. The intensity of power Doppler flow pattern was not correlated with the severity of the disease. This study demonstrated that power Doppler sonography is a convenient, time saving, inexpensive and noninvasive method as compared with isotope scan and some other laboratory tests for confirmation of Graves’ disease. © 1999 Elsevier Science Ireland Ltd.
Primary Extraskeletal Ewing Sarcoma Originating From Chest Wall in a Child
(TIP ARASTIRMALARI DERNEGI, 2010) Avcu, S.; Akdeniz, H.; Bora, A.; Arslan, H.; Ünal, Ö.
We report the ultrasonography (US) and computed tomography (CT) findings of a rare case of extraskeletal Ewing sarcoma involving the left chest wall with a diameter of 4cm in a 5 years old girl. The lesion was heterogenously hypoechoic on sonography with a lobulated smooth contour. On CT, the lesion had central necrotic areas and was enhancing heterogeneously. With these US and CT findings surgical excision of the tumor was performed. Histopathologically the mass was evaluated as round cell malignant neoplasm (Ewing tumor/ "Askin tumor"/ primitive neuroectodermal tumor (PNET)). Chemotherapy and radiotherapy were planned to the patient.
The Relation Between Pelvic Varicose Veins and Lower Extremity Venous Insufficiency in Women With Chronic Pelvic Pain
(Assoc Royal Soc Scientifiques Medicales Belges, 2012) Bora, A.; Avcu, S.; Arslan, H.; Adali, E.; Bulut, M. D.
Purpose: To determine the relation between pelvic varicose veins and lower extremity venous insufficiency in women with chronic pelvic pain. Methods and Materials: This study was done in Yuzuncu Yil University Faculty of Medicine, Department of Radiology, with patients who were referred for abdominal and pelvic imaging between January 2007 and April 2008. A total of 1029 women with pelvic imaging study were included in the study. The presence of venous dilatations (diameter > 5 mm) in parauterine and paraovarian localizations were accepted as pelvic varicose veins. In all patients, endometrial thickness was measured and lower extremity venous system was examined with Doppler ultrasonography to assess possible associated venous insufficiency. All patients were undergone questionnaire for frequency of delivery, age, and chronic pelvic pain. Results: Pelvic varicose veins were discovered with transabdominal ultrasound and computerized tomography in 56 of 1029 patients. Various degrees of associated lower extremity venous insufficiency were also discovered in 44 of 56 patients (78,6%) with pelvic venous dilatation. Of the 44 patients with lower extremity venous insufficiency, 21 were bilateral, 9 were right-sided, and 14 were left-sided. Endometrial thickness was significantly increased in patients with pelvic venous dilatation. Conclusion:The presence of pelvic varicose veins is significantly associated with lower extremity venous insufficiency. Since the diagnosis of lower extremity venous insufficiency plays an important role in deciding the course of treatment, lower extremity Doppler ultrasonography examination would be useful to include in the evaluation of pelvic varicose veins.
Relationship Between Biomass Exposure, Chronic Headache and Brain Damage in Young Women
(Yuzuncu Yil Universitesi Tip Fakultesi, 2020) Arslan, A.; Tüzün, F.A.; Arslan, H.
Biomass, an energy source, is the general name of all non-fossilized biological material obtained from living or recently living organism. Household use of solid biomass fuels is the most common cause of indoor air pollution (IAP) worldwide. The aim of this study was to investigate the relationship between biomass exposure and the presence of headache and brain damage in young women. This cross-sectional study included patient group consisted of 69 women who applied to the neurology outpatient clinic with complaints of chronic headache and fatigue and the control group consisted of 26 healthy volunteer women who were not exposed to tandir smoke. In all subjects, blood samples were obtained for biochemical analysis and brain Magnetic Resonance Imaging (MRI) scan was performed to evaluate brain damage. In the patient group, ischemic gliotic foci were detected in 56 patient (81.2%) while in the control group, gliotic foci was detected in 3 subjects (11.5%). The prevalence of gliotic foci was almost 8 times higher in subjects with a history of biomass smoke exposure than in subjects without a history of biomass smoke exposure (81.2% vs. 11.5%). These findings suggest that indoor air pollution may have an effect on the risk of headache and brain damage. However additional studies with larger sample sizes and including other ethnic or environmental communities are needed to determine in detail the role of indoor air pollution in the occurrence of headaches and brain damage. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi.
