Article Acute Respiratory Distress Syndrome Occurred After Hanging Result of the Attached To Rope: a Case Report(Aves, 2012) Kaya, Avni; Okur, Mesut; Akbayram, Sinan; Avcu, Serhat; Acikgoz, Mehmet; Dogan, Murat; Akil, MuhammedA-13-year-old male patient was admitted to our emergency unit because of near-hanging while playing with a rope. On physical examination, his general condition was not good, his state of consciousness was evaluated to be stuporous and his spontaneous respiration was weak. The patient had been intubated. The Glasgow coma score was 7. Rope marks were observed on his neck. Thorax computed tomography revealed widespread ground-glass appearance and bilateral parenchymal consolidation in the lungs. This findings correlated with acute respiratory distress syndrome. This case was reported for reminding that acute respiratory distress syndrome can be associated with near-hanging.

Material and methods: Hemodialysis patients were evaluated with B-mode ultrasonography (USG). Participants in the prospective group were evaluated using USG prior to catheter insertion, 10 days after catheter insertion, at the time of catheter removal, and 15 days after removal. Results: The rate of thrombosis was increased correlated with the number of catheter insertions. These rates were 14%, 15%, and 47% in those undergoing catheter insertion once, twice, and three times, respectively (P < .05). The anatomical variations of IJV were 21% in the retrospective cases. No significant relationship was found between anatomical variations and thrombosis and between some biochemical parameters and thrombosis. Conclusion: Catheter-related IJV thrombosis is frequent in hemodialysis patients. Long catheter remaining time and repeated catheterization increase the thrombosis rate.Article Atypical Virchow-Robin Spaces: Report of Seven Cases(Ortadogu Ad Pres & Publ Co, 2010) Avcu, Serhat; Sayin, Refah; Unal, Ozkan; Cogen, Etem Emre; Tombul, TemelThe term "Virchow-Robin spaces" (VRS) refers to the extension of the subarachnoid space accompanying a vessel penetrating the cerebral cortex. In case of widening, they can be seen on magnetic resonance imaging as round, oval, or curvilinear well-defined cystic lesions with smooth margins, isointense to cerebrospinal fluid. Although dilated VRS are normal findings that may be seen at all ages, big and atypical forms are rare. Although they have associated mass effect, they should not be mistaken for neoplasm or other disease. We report seven patients whose ages were between 7 and 66 (mean: 35.8) years showing unilateral or bilateral cerebral intraparenchymal extensive cystic dilations corresponding to atypical VRS (two with Type-I and five with Type-II VRS), with clinical and radiological findings.Article Bilateral Optic Atrophy Related To Juvenile Nasopharyngeal Angiofibroma(Taylor & Francis As, 2008) Caglar, Cagatay; Cinal, Adnan; Avcu, SerhatJuvenile nasopharyngeal angiofibroma (JNA) is one of the most common benign nasal cavity tumors of adolescence. This tumor has the capacity to locally expand. It can cause ocular manifestations such as proptosis, decreased visual acuity, and visual field deficits. In our case, JNA caused visual loss in both eyes. Our case showed that despite the fact that the tumor is benign, it can cause serious complications, such as blindness. Therefore, early diagnosis and treatment is crucial for this type of tumor and an ophthalmologist should be most alert for symptoms of JNA.Article A Case of Enchondromatosis Concomitant With Cerebral Hamartomas: Radiologic Findings(Taylor & Francis inc, 2011) Avcu, Serhat; Cetin, Feray; Unal, OzkanEnchondromatosis is a congenital nonhereditary condition characterized by multiple symmetrically distributed intraosseous cartillaginous masses in the metaphyses and diaphyses of bones. We report a case of bilateral multiple enchondromas and cerebral hamartomas in an 11-year-old boy in whom x-rays displayed distortion and expansion of bilateral long tubuler bones, hands and feet, scapulas, pelvis, and occipital regions of the calvarium. In addition to osseous abnormalities, bilateral cerebral hamartomas were observed on cranial magnetic resonance imaging (MRI). To the best of our knowledge, this is the first case in the literature with enchondromatosis and cerebral hamartomas.Article A Case of Primary Vertebral Osteosarcoma Metastasizing To Pancreas(E S Burioni Ricerche Bibliografiche, 2009) Avcu, Serhat; Akdeniz, Huseyin; Arslan, Harun; Toprak, Nursen; Unal, OzkanContext Osteosarcoma is the most common malignant bone tumor in children and adolescents and possesses a high potential for metastasis. The most common sites of osteosarcomatous metastases are the lungs, pleurae, and bone; the pancreas being extremely rare. Case report We report the computed tomography findings of a rare case of pancreatic metastasis in a 14-year-old boy with primary vertebral osteosarcoma being followed-up for 6 years. On abdominal CT, a huge mass containing necrotic and calcified areas and causing bone destruction was seen between thoracic vertebra 7 and sacral vertebra 1 involving both the vertebrae and paravertebral soft-tissue. A large metastatic mass with an irregular contour was also visualized in the pancreatic head and peripancreatic region having tomographic findings similar to the vertebral mass. Tru-cut biopsy of the pancreatic mass confirmed the diagnosis of osteosarcoma metastasis. Conclusions Although extremely rare, osteosarcoma metastasis should be included in the differential diagnosis of pancreatic mass lesions, particularly in patients with a primary tumor.Article A Case Report of a Patient With Cleft Palate Carrying the Risk of Tetraplegia(Alliance Communications Group Division Allen Press, 2011) Isik, Daghan; Guner, Savas; Avcu, Serhat; Goktas, Ugur; Atik, BekirSpondyloepiphyseal dysplasia congenita (SEDC) is an inherited disorder of bone growth that results in short-trunk dwarfism, skeletal abnormalities, disorders in vision and hearing, atlanto-axial instability, and cleft palate. This important anomaly of the cervical vertebrae carries the risk of tetraplegia during cleft palate operations. In this case report, we discuss a case of spondyloepiphyseal dysplasia congenita, the perioperative and postoperative measures, and the risk of tetraplegia.Article Case Report: Budd–chiari Syndrome and Esophageal Variceal Bleeding Due To Alveolar Echinococcosis(2010) Dülger, Ahmet Cumhur; Avcu, Serhat; Akdenız, Hüseyın; Kemik, Özgür; Küçükoğlu, Mehmet EminKaraciğerin alveoler ekinokoku Echinococcus multilocularis'e bağlı nadir bir sestod hastalığıdır. Bu sestod, larval dönemini etobur hayvanlarda kistler içinde tamamlar. İnsanlar rastlantısal ara konaklar olup vahşi etoburların yumurtaları ile bulaşmış yiyecekler aracılığıyla veya tilkilere dokunmakla hastalığı edinirler. Hastalık malign karaciğer tümörleri gibi seyir gösterir ve çok nadiren de Budd- Chiari sendromu ve özofagus varis kanamasına neden olur. Budd–Chiari sendromu hepatik venlerin tıkanması ve karın ağrısı, hepatomegali ve asitle ortaya çıkan bir hastalıktır. Paraziter kistler hepatik venöz sisteme dıştan bası yolu ile veya tromboza neden olarak bu hastalığa neden olurlar. Bazen de portal hipertansiyon ve özofagus varis kanamasına neden olabilir. Bizler; daha önceden bilinen bir karaciğer hastalığı olmayan 47 yaşındaki bir kadın hastada Alveoler ekinokok hastalığına bağlı gelişen bir Budd–Chiari sendromu ve varis kanaması olgusunu sunuyoruz. Hastalığın seyri önemli laboratuar, serolojik ve radyolojik ölçütlerle gösterilmiştir.Article Chronic Effects of Environmental Biomass Smoke on Lung Histopathology in Turkish Non-Smoking Women: a Case Series(inst Medical Research & Occupational Health, 2012) Gunbatar, Hulya; Sertogullarindan, Bunyamin; Ozbay, Bulent; Avcu, Serhat; Bulut, Gulay; Kosem, MustafaBiomass is widely used for fuel in developing countries. Particles and gases of biomass burning may cause changes in the lung. In this prospective study we investigated histopathological changes in the lungs of 42 non-smoking women [mean age (59 +/- 10) years] caused by biomass smoke. We valuated exposure to biomass smoke, case histories, and the findings of physical examination, radiology, bronchoscopy, and lung histopathology. Mean exposure to biomass smoke was (28 +/- 9) hour-year (1 hour-year equals 365 hours of exposure per year with average exposure of 1 hour a day). The radiological findings were mass (42 %), reticulonodular opacities (31 %), mediastinal lymphadenopathy (26 %), pleuro-parenchymal fibrotic banding (19 %), widening of the pulmonary artery (14 %), ground glass (11 %), mosaic perfusion (9 %), consolidation (9 %), segmental or subsegmental atelectasis (7 %), and bronchiectasis (7 %). The patients were diagnosed with lung cancer (35 %), interstitial lung disease (31 %), sarcoidosis (9 %), tuberculosis (9 %), chronic obstructive pulmonary disease (4 %), chronic bronchitis (9 %), and metastasis (4 %). Bronchoscopy showed pilies, oedema, erythema, bronchus narrowing, endobronchial tumour, mucosal irregularity, increased vascularisation, blue-black anthracotic plaques, mucosal oedema, and purulent secretion. Transbronchial biopsies revealed neutrophil and lymphocyte leucocytes in the perivascular, peribronchiolar, and interalveolar septa, slightly enlarged connective tissue, thickening of the basal membrane, thickening of interalveolar septa, intimal and medial thickening of the vascular wall and vascular lumen narrowing, anthracosis between the cells and in the bronchiole epithelium. These findings confirm that biomass smoke has important toxic effects on the lung parenchyma, interstitium, and pulmonary vessels that may result in malignancies.Article Cine Phase-Contrast Mri Evaluation of Normal Aqueductal Cerebrospinal Fluid Flow According To Sex and Age(Aves, 2009) Unal, Ozkan; Kartum, Alp; Avcu, Serhat; Etlik, Omer; Arslan, Halil; Bora, AydinPURPOSE The aim of this study was cerebrospinal flow quantification in the cerebral aqueduct using cine phase-contrast magnetic resonance imaging (MRI) technique in both sexes and five different age groups to provide normative data. MATERIALS AND METHODS Sixty subjects with no cerebral pathology were included in this study. Subjects were divided into five age groups: <= 14 years, 15-24 years, 25-34 years, 35-44 years, and >= 45 years. Phase, rephase, and magnitude images were acquired by 1.5 T MR unit at the level of cerebral aqueduct with spoiled gradient echo through-plane, which is a cine phase-contrast sequence. At this level, peak flow velocity (cm/s), average flow rate (cm/s), average flow (L/min), volumes in cranial and caudal directions (mL), and net volumes (mL) were studied. RESULTS There was a statistically significant difference in peak flow between the age group of <= 14 years and the older age groups. There were no statistically significant differences in average velocity, cranial and caudal volume, net volume, and average flow parameters among different age groups. Statistically significant differences were not detected in flow parameters between sexes. CONCLUSION When using cine-phase contrast MRI in the cerebral aqueduct, only the peak velocity showed a statistically significant difference between age groups; it was higher in subjects aged <= 14 years than those in older age groups. When performing age-dependent clinical studies including adolescents, this should be taken into consideration.Editorial Coexistence of Neurofibromatosis Type-1, Left Internal Carotid Artery Hypoplasia and Left Phytisis Bulbi(Galenos Publ House, 2011) Avcu, Serhat; Akdeniz, Huseyin; Unal, Ozkan; Arslan, Harun; Bora, AydinCongenital abnormalities of the internal carotid artery (ICA) are extremely rare and aplasia/hypoplasia of the ICA associated with other congenital malformations is uncommon. An 8-year-old male patient was admitted to our hospital for extreme nervousness, attention problems and hyperactivity. On MR examination, left phytisis bulbi, left frontal lobe atrophy, assymmetric dilataion in the left lateral ventricle and hamartomas in both globus pallidi, right thalamus, and bilateral cerebellar hemispheres posterior to the fourth ventricle were observed. Left ICA was observed as hypoplastic in the cervical and cranial MR-angiography. Left MCA and ACA could not be visualised. Left carotid canal hypoplasia and left sphenoidal bone dysplasia were detected on CT. As far as we know, only 4 cases with concomitancy of ICA hypoplasia-NF Type-1 have been reported up to the present. In our case, in addition, phytisis bulbi is accompanying this coexistence.Article Compartment Syndrome Due To Extravasation of Iodixanol Contrast Medium: Case Report(Ortadogu Ad Pres & Publ Co, 2012) Guner, Savas; Ceylan, M. Fethi; Avcu, Serhat; Guner, S. Ilkay; Dogan, AliCompartment syndrome due to extravasation of contrast medium is quite rare. The content of the contrast medium, the osmolarity, the ionic/non-ionic structure and the amount of extravasated medium are important factors in the pathogenesis of extravasation injury. Many extravasations are of small volumes causing minimal swelling and erythema. Extravasations of large volumes are important in the development of compartment syndrome due to the non-ionic contrast medium. Early diagnosis is very important in the contrast medium extravasations and conservative treatment is effective in most of the patients. If compartment syndrome develops after extravasation, emergency fasciotomy should be performed immediately. To the best of our knowledge, compartment syndrome due to extravasation of a non-ionic contrast medium, iodixanol, has not previously been reported in the English literature. In this article, a case of extravasation and compartment syndrome due to the administration of iodixanol for thoracic tomography and its treatment was first reported.Article Cortical Dysplasias, and Corpus Callosum and Posterior Fossa Abnormalities Correlation of Clinical Findings With Magnetic Resonance Imaging (Mri) Characteristics(Sage Publications inc, 2014) Caksen, Huseyin; Kizilyildiz, Baran Serdar; Avcu, SerhatThis study examined clinical findings and magnetic resonance imaging (MRI) characteristics in 114 patients with cortical dysplasia and corpus callosum and posterior fossa abnormalities to determine the clinical findings with the extent of the lesions on MRI. The age of patients was between 1 day and 15 years. Group 1 included 74 patients with corpus callosum abnormalities and/or cortical dysplasias and group 2 included 40 patients with posterior fossa abnormalities, which were isolated and/or associated with cortical dysplasia and/or corpus callosum abnormalities. Although associated congenital abnormality apart from central nervous system abnormalities, syndrome, or systemic disorder were more common in group 2 than group 1 patients (P < .05), we did not find a difference between the groups for psychomotor retardation and epilepsy (P > .05).Article The Detection of Eagle's Syndrome With Three-Dimensional Multidetector Computerized Tomography (Ct)(Professional Medical Publications, 2010) Yuca, Koksal; Avcu, Serhat; Kiroglu, A. Faruk; Etlik, Omer; Cankaya, Hakan; Kiris, MuzafferObjective: Eagle's Syndrome is caused by elongation of the styloid process or ossification of the stylohyoid ligament. We aimed to evaluate the contribution of 3-Dimensional Multidetector CT findings on Eagle's syndrome. Methodology: Three-Dimensional Multidetector CT were performed on 13 patients with Eagle's syndrome. Maximum intensity projection (MIP) and volume rendering (VR) images having optimal resolution in all patients were obtained using 3D reconstructions on work-station. Styloid process and its extension, and stylohyoid ligament were evaluated. A styloid processes e '' 3cm were accepted to be longer than normal. We also had a control group of patients which consisted of ten patients who had no complaints of dysphagia, throat pain, or foreign body sensation in the throat. Results: Elongation of the styloid process was revealed by 3D VR imaging in all patients. We found elongated styloid process bilaterally in two patients. Elongation of the styloid process was clearly revealed by 3D VR imaging in high contrast and spatial resolution under the anatomic orientation like conventional X-ray in all patients. The diagnosis of Eagle's syndrome was confirmed surgically in four of 13 patients. Conclusion: We conclude that 3D VR imaging is a valuable diagnostic method in detecting elongated styloid process.Article The Diagnostic Value of Diffusion-Weighted Magnetic Resonance Imaging in Soft Tissue Abscesses(Elsevier Ireland Ltd, 2011) Unal, Ozkan; Koparan, Halil Ibrahim; Avcu, Serhat; Kalender, Ali Murat; Kisli, ErolPurpose: To study the diagnostic value of diffusion-weighted imaging (DWI) in soft tissue abscesses. Materials and methods: Fifty patients were included in this study who were thought to have soft tissue abscess or cystic lesion as a result of clinical and radiological examinations. Localisations of the lesions were: 1 periorbital, 3 breast, 14 intraabdominal, and 32 intramuscular lesions. After other radiological examinations, DWI was performed. The signal intensity values of the lesions were evaluated qualitatively according to the hyperintensity on b-1000 DWI, using 1.5 T MR system. All of the lesions were aspirated after DWI, and detection of pus in the aspiration material was accepted as gold standard for the diagnosis of abscess. Results: In 38 of the 50 patients, hyperintensity was obtained on diffusion-weighted images. False-positive results were maintained in 2 of these patients, and true-positive results were maintained in 36 of them. In 11 of the 50 patients, hypointensity was visualised on diffusion-weighted images. False-negative results were maintained in 3 of these patients, and true-negative results were maintained in 8 of them. An abscess which was seen on post-contrast conventional MRI could not be seen on DWI, and this was regarded as false-negative. Conclusion: The sensitivity and specificity of diffusion-weighted images for detecting soft tissue abscesses were found to be 92% and 80%, respectively. DWI has a high diagnostic value in soft tissue abscesses, and is an important imaging modality that may be used for the differentiation of cysts and abscesses. (C) 2009 Elsevier Ireland Ltd.

Material/Methods: Thirty-seven women (age range: 22-77 years, mean: 43.7 years) with 76 breast lesions were included in this study. Dynamic post-contrast images with 0.2 mL/kg gadobutrol (Gadovist) injection were obtained in all patients. Contrast-to-noise-ratio (CNR) of the lesions, as well as their contrast enhancement patterns (ring, heterogeneous, homogenous), and perilesional increased vascularity were studied. Results: Fifty-six benign and 20 malignant lesions were examined histopathologically. In malignant cases, heterogeneous and peripheral enhancements were most commonly determined, whereas homogeneous enhancement was most commonly determined in benign cases. CNR was 450% in malignant lesions, and 60% in benign lesions. Conclusions: Type II/III contrast-time curves, ring/heterogeneous enhancement, prominent increase in CNR, and perilesional vascularity increase are important findings determining malignancy, whereas Type I curves, homogenous enhancement, a slight increase in CNR, and absence of perilesional vascularity increase support findings of benign breast lesions. By increasing CNR and providing increased perilesional vascularity, Gadovist can help in the determination of malignant breast lesions.Article The Efficiency of Apparent Diffusion Coefficient Quantification in Diagnosis of Acute Cholecystitis and in Differentiation of Cholecystitis From Extrinsic Benign Gallbladder Wall Thickening(Springer, 2014) Beyazal, Mehmet; Avcu, Serhat; Celiker, Fatma Beyazal; Yavuz, Alpaslan; Toktas, OsmanThe aim of the current study was to assess the efficiency of the apparent diffusion coefficient (ADC) measurement in diagnosis of acute cholecystitis and in differentiation of cholecystitis from extrinsic benign gallbladder wall thickening. Forty patients who were diagnosed to have acute cholecystitis by ultrasonographic examination were included in this study. The control group consisted of 18 patients without symptoms of gallstones and cholecystitis whose gallbladder walls were thickened due to cirrhotic ascites. Both groups were examined using diffusion weighted imaging, and the mean ADC values were compared using Student's t-test. The diagnoses of the 40 patients were proven by histopathological examination. The mean ADC values of patients diagnosed with cholecystitis (1.68 +/- A 0.36 x 10(-3) mm(2)/s) were significantly lower than the mean ADC values of the control group (2.35 +/- A 0.24 x 10(-3) mm(2)/s) (p < 0.05). Receiver operating characteristics curve analysis based on ADC revealed a cut-off value of 2.04 x 10(-3) mm(2)/s for the diagnosis of cholecystitis, with a sensitivity of 94 % and a specificity of 89.7 %. ADC value quantification may be an efficient method for making a diagnosis of cholecystitis and in differential diagnosis of cholecystitis from the extrinsic benign gallbladder wall thickening that can be seen during the course of cirrhotic ascites.specialization-in-medicine.listelement.badge Efficiency of Endovenous Laser Ablation Method in the Treatment of Lower Extremity Superficial Venous Insufficiency(2012) Beyazal, Mehmet; Avcu, SerhatAmaç: Varriköz venlerle ilişkili olan yüzeyel venöz yetmezlik yaygın bir problemdir ve tedavi edilmezse venöz ülserasyonla sonuçlanabilir.

The purpose of this study is to assess the changes in renal vasculature with spectral Doppler sonog-raphy in patients with VUR. In addition, the possible effects of voiding cystoureterography (VCU) on the kidneys in patients with VUR are investigated by calculating renal resistivity index (RI) values before and after VCU using spectral Doppler sonography. In this prospective study, 114 kidneys of 58 children ages 0 to 16 years were included. The RI values that were calculated before and after VCU and RI values in different grades of VUR were compared statistically. In patients with VUR, the renal parenchymal RI values before and after VCU were significantly higher than those in patients without VUR (P < .05). The mean pre-VCU RI values were 0.68 +/- 0.03 and 0.65 +/- 0.05 in patients with VUR and in the control group, respectively, and the mean post-VCU RI values were 0.68 +/- 0.03 and 0.65 +/- 0.04 in patients with VUR and in the control group, respectively. Calculating renal RI values from arcuate or interlobar renal arteries with spectral Doppler sonography while the patients are in a supine or lateral decubitus position is a useful technique in patients with VUR, being significantly higher in high-grade VUR patients than in low-grade VUR patients. There is no significant effect of the contrast agent reaching the renal calycial system during VCU examination on renal RI values.
