Item A mass screening survey of cystic echinococcosis by ultrasonography, Western blotting, and ELISA among university students in Manisa, Turkey(2013) Kilimcioǧlu A.A.; Girginkardeşler N.; Korkmaz M.; Özkol M.; Düzgün F.; Östan T.; Pabuşcu Y.; Dinç G.; Ok T.Z.Cystic echinococcosis (CE) is one of the most important zoonotic diseases in a wide geographic area, including Turkey. In the present project, a total of 4275 students from Celal Bayar University, Manisa, Turkey, were screened by ultrasonography (US) and specific antibodies for CE were examined by Western blotting (WB) and ELISA in finger prick blood samples of 2034 of 4275 volunteered students. We aimed to report the apparent prevalence of CE based on different diagnostic procedures and to compare WB and ELISA with US in diagnosis of CE in a mass screening setting. Six new cases were diagnosed as CE by US during the survey. In addition to these cases, three students were also detected to have been previously operated and pathologically confirmed for hepatic CE. US revealed parenchymal changes in these cases in concordance with their operation history; so, the prevalence of CE by US was calculated as 0.21% (9/4275) (95%CI, 0.11-0.39%) among university students in Manisa. Bands were detected at 8, 28, 32, 38, 42, 47, 70 and 90. kDa by WB and the cases were considered to be positive for CE when at least three of the bands were seen together. Apparent prevalence of CE by ELISA and WB were found to be 2.11% (43/2034) (95%CI, 1.57-2.83%) and 0.25% (5/2034) (95%CI, 0.10-0.57%), respectively. Of the six US positive cases, WB was positive in only one case with two cysts in the liver. All of four cases with liver involvement were positive by ELISA. The high prevalence of CE among university students in Manisa indicated that CE is a major health problem in this area of Turkey. Our results supported that WB is rather difficult and not feasible as a mass screening test and may not be effective for confirmation especially in asymptomatic cases. As a result, we recommend US to be used initially in mass screening surveys for CE followed by confirmation by ELISA for suspected cases. Further examination primarily by chest X-ray followed by computed tomography and/or magnetic resonance imaging, if needed, should be recommended for US negative, ELISA and WB positive individuals who may have non-abdominal cysts. © 2013 Elsevier B.V.Item Idiopathic thoracic spinal epidural lipomatosis causing spinal cord compression(Elsevier Inc., 2016) Korkmaz M.; Gök M.; Bozkaya H.; Güneyli S.; Düzgün F.; Oran İ.[No abstract available]Item Progressive spinal epidural hemangioma in pregnancy(Elsevier Inc., 2016) Korkmaz M.; Gök M.; Çınar C.; Güneyli S.; Düzgün F.; Oran İ.[No abstract available]Item Neonatal Cholestasis as Initial Presentation of Portosystemic Shunt: A Case Report(Elsevier B.V., 2016) Doğan G.; Düzgün F.; Tarhan S.; Appak Y.Ç.; Kasırga E.Congenital intrahepatic portosystemic shunts are rare in children. Portosystemic venous malformations are characterized by extreme clinical variability. We report a full-term 33-day-old male infant presenting with neonatal jaundice. On physical examination, he had generalized icterus and the liver was palpable 3.5 cm below the right costal margin. He had no other symptoms. Laboratory tests showed AST 632 U/L, ALT 198 U/L, total bilirubin 12.1 mg/dL, conjugated bilirubin 10.2 mg/dL, alkaline phosphatase 753 U/L, GGT 47 U/L and glucose 67 U/L. Colour Doppler ultrasonography showed the left portal vein was more dilated than the right portal branch and communication with dilated left hepatic vein. There was no evidence of portal hypertension, heart failure, hepatopulmonary syndrome and encephalopathy during his hospital stay, so he was discharged from the pediatric department and his parents advised to attend monthly follow-up. Congenital portosystemic shunts are rarely observed in the childhood period.1 Depending on anatomic characteristics they may be intrahepatic or extrahepatic.2 Intrahepatic portosystemic shunts (PSS) are observed between the portal vein and hepatic vein or vena cava inferior.3,4 Small shunts may close themselves before the age of 2 years.5 With the increase in use of imaging methods, diagnosing PSS has become easier, with an increase in the number of cases reported.6 Neonatal cholestatis is a frequent complication of PSS.1 We present a case presenting with neonatal cholestasis diagnosed with congenital intrahepatic PSS. © 2016Item The short-and long-Term effectiveness of transcatheter arterial embolization in patients with intractable hematuria(Elsevier Masson SAS, 2016) Korkmaz M.; Åžanal B.; Aras B.; Bozkaya H.; Çlnar C.; Güneyli S.; Gök M.; Adam G.; Düzgün F.; Oran I.Purpose: Selective transarterial embolization (TAE) of the internal iliac artery is a well-known alternative technique to control intractable bladder hemorrhage (IBH). We explored the shortand long-term effectiveness of, and clinical outcomes after, TAE in patients with IBH. Materials and methods: In this retrospective study, we reviewed the hospital records of 18 IBH patients non-responsive to conservative medications who underwent TAE between January 2003 and May 2014. The early- and long-term effectiveness of TAE was investigated in the context of hematuria control, complications, mortality, requirement for blood transfusions, and hematocrit level. Results: Sixteen of the 18 patients underwent endovascular treatment; the technical success rate was 88%. TAE allowed complete remission in 16 patients (100% clinical success). On follow-up, mean hematocrit (P = 0.003) and hemoglobin (P = 0.005) levels significantly improved. Thirteen of the 16 patients (81%) required no further emergency admission after TAE during a mean follow-up period of 18.1 months (range, 3-105 months). Conclusion: TAE is a feasible, effective, and safe technique in both the short- and long-term for the treatment of IBH. © 2015 Éditions françaises de radiologie.Item Benign versus malignant vertebral compression, chemical shift MR imaging, is it useful?(Kowsar Medical Institute, 2017) Yilmaz Ovali G.; Düzgün F.; Farasat M.; Orguc S.Objectives: The aim of this study was to evaluate the diagnostic accuracy of chemical shift imaging in vertebral compression. Patients and Methods: Forty-nine patients with vertebral compression with suspected malignancy or history of trauma were included in this study. MR imaging of the spine with standard conventional MR sequences and additional chemical shift imaging was done with 1.5 Tesla MR Unit. Regions of interest (ROI) were placed on the abnormal marrow of compressed vertebrae both on the opposed phase and on the matching in phase images and signal intensity (SI) ratio values (SI out-phase/SI-in phase) were calculated. Results: Forty-nine patients had 68 spine lesions, consisting of 49 benign and 19 malignant fractures. Student t test, receiver operating characteristic (ROC) analysis and interclass correlation test were used statistically. Mean SI ratio of benign vertebral compression (0. 68 ± 0.29, range 0.13 - 1.53) was significantly lower than malignant SI ratio values (1.06 ± 0.10, range 0.96 - 1.35). With student t-test, there was significant difference between benign compressions compared to malignant compressions (P < 0.001). Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut off value in malignant and benign lesion definition. The optimal SI ratio cut off value was found to be 0.96 for separating benign and malignant vertebral compression. The area under the curve (AUC) value was observed as 0.92 (95% confidence interval [CI] = 0.86 - 0.99). According to that cutoff value, sensitivity was 100% (95% CI = 82.35% - 100%) and the specificity was 86% (95% CI = 72.76% - 94.06%). Interobserver reliability was studied with intraclass correlation and results were statistically significant with intraclass correlation coefficient (ICC) as 0.85 (P < 0.05). Conclusions: There is significant difference in signal values between benign and malignant compression fractures in chemical shift MR imaging. Chemical shift MR imaging has much additive data to conventional MRI in vertebral compression. © 2016, Tehran University of Medical Sciences and Iranian Society of Radiology.Item Endovascular coil treatment of a coronary artery aneurysm related to polyarteritis nodosa(Turkish Society of Cardiology, 2017) Bayturan Ö.; Tarhan S.; Çöpkıran Ö.; Düzgün F.; Tezcan U.K.[No abstract available]Item Multislice computed tomographic measurements of optic nerve sheath diameter in brain injury patients; [Beyin hasarı olan hastalarda çok kesitli bilgisayarlı tomografide optik sinir kılıfı ölçümleri](Turkish Association of Trauma and Emergency Surgery, 2018) Özsaraç M.; Düzgün F.; Gölcük Y.; Pabuşcu Y.; Bilge A.; İrik M.; Yılmaz H.BACKGROUND: Currently, the measurement of optic nerve sheath diameter (ONSD) has been offered as a possible indicator of intracranial pressure (ICP). Increased ICP is observed during intracranial injury. The objective of this study was to evaluate the relationship between increased ONSD and positive intracranial findings from multislice computed tomography (CT) of the brain. METHODS: In total, CT scans of 161 patients were retrospectively reviewed. The image that showed the largest ONSD was magnified five times. RESULTS: The CT scan revealed intracranial lesions in 54 patients and no intracranial lesions in 107 patients. A significant relationship was observed between positive CT findings and increased ONSD: 5.60±0.75 mm vs. 5.35±0.75 mm (p=0.038). The area under the receiver operating characteristic curve was 0.600 (95% confidence interval, 0.508–0.692; p<0.039). A cut-off value of ≥5.0 mm had a sensitivity and specificity of 80% and 36%, respectively. CONCLUSION: This study demonstrated a significant yet poor relationship between intracranial injury and increased ONSD from the multislice CT scan. Severe structural changes in the brain and trauma that causes bleeding have only limited effects on the extension of the optic nerve. © 2018 Turkish Association of Trauma and Emergency Surgery.Item Percutaneous embolization of congenital portosystemic venous shunt in an infant with respiratory distress(Turkish Journal of Pediatrics, 2018) Alkan F.; Düzgün F.; Yüksel H.; Tarhan S.; Coşkun Ş.A 5-month-old boy with progressive respiratory distress was admitted to our hospital. Physical examination revealed mild tachypnea and retraction. The left main bronchus was found as severely collapsed between the right pulmonary artery and the descending aorta, on the bronchoscopic evaluation. Further evaluation revealed persistent ductus venosus (PDV). As in the fetal period the ductus venosus arises from the posterior aspect of the left portal vein, a PDV is considered another type of intrahepatic portosystemic shunt. Therefore, he was diagnosed with congenital portosystemic venous shunt, leading to persistent respiratory distress. The PDV was closed with Amplatzer vascular plug II, and then he had immediate clinical improvement. Congenital portosystemic venous shunts (CPSS) are rare vascular malformations associated with severe complications. Here we presented a case with progressive respiratory distress as a result of CPSS and rapid improvement after embolization. © 2018, Turkish Journal of Pediatrics.

In this study we aimed to investigate the relationship between carotid intima media thickness (CIMT) one of the earliest findings of atherosclerosis and markers of glomerular inflammation. Materials and Methods:40 patients with biopsy proven glomerulonephritis and 46 healthy controls were enrolled in the study. Human Growth arrest spesific protein 6 (Gas6) levels in serum samples were studied by ELISA. CIMT measurement was performed by the same radiologist. Neutrophil-lymphocyte ratio (NLR) was calculated by dividing the number of neutrophils by the number of lymphocytes. Results: The mean age was 42.88±15.41 in patient group and 38.26±9.04 in controls. The mean duration of illness was 29.07±52.90 mounts, proteinuria was 4027.05±4030.22 mg/day, Modification of Diet in Renal Diseases Study Glomerular Filtration Rate (MDRD-GFR) was 53.80±48.32 mL/min/1.73m2. CIMT was 0.62±0.17 mm in patient group, 0.46±0.10 mm in controls. Neutrophil-to-Lymphocyte Ratio (NLR) was 3.69±4.46 in patient group and significantly higher than control group (1.74±0.63). Gas6 levels were statistically higher in control group. CIMT was positively correlated with age, fibrinogen, ferritin, proteinuria and NLR and negatively correlated with HDL cholesterol and Gas6 in glomerulonephritis group. Age was the predictor for CIMT in the logistic regression model. In all group CIMT was positively correlated with age, creatinine, uric acid, fibrinogen, ferritin, CaxP product, proteinuria and NLR and negatively correlated with hemoglobin level, Gas6. In lineer logistic regression analysis carotid IMT was significantly associated with age and ferritin and proteinuria. Conclusion: We have shown that proteinuria is one of the main determinants of increased CIMT independent from the GFR levels in glomerulonephritis with relatively preserved glomerular filtration rate. © 2019, Pamukkale University.

An 18-year-old girl presented to the hospital with abdominal pain and distension. Abdominal tenderness and grade 2 ascites, serious peripheral eosinophilia and high immunoglobulin E level were found. Laparoscopic antrum biopsy showed subserosal eosinophilic infiltration. Eosinophilic gastroenteropathy was suspected, diet elimination was given, no steroid treatment was used. © Copyright 2020 by Ege University Faculty of Medicine, Department of Pediatrics and Ege Children's FoundationItem Long term follow-up results of ablation treatment for patients with small renal mass(John Wiley and Sons Inc, 2021) Gümüş B.H.; Albaz A.C.; Düzgün F.; Üçer O.; Temeltaş G.; Müezzinoğlu T.; Tarhan S.Objective: The aim of this study is to evaluate the outcome of ablation therapy in our clinic for the treatment of patients with a small renal mass Materials and Methods: We retrospectively evaluated the technic and follow-up data of 30 patients with 36 tumours who underwent Radiofrequency Ablation (RFA) and Microwave Ablation (MWA) in our clinic. Demographic data, ablation type, tumour characteristics, peroperative and postoperative complications and treatment success of the patients were evaluated. Results: A total of 36 tumours who underwent ablation treatments, 23 were treated with RFA, 13 with MWA. The mean tumour size was 28.9 ± 6.92 mm in RFA and 29.3 ± 7.70 mm in MWA. The mean follow-up period was 49.6 ± 24.7 months in patients with RFA and mean follow-up was 16 ± 8.05 months in MWA treatments. The overall success in MWA administration was calculated as 76.9%, while the overall success in RFA was 80%. Conclusion: Long-term oncologic efficacy of RFA appears to be successful in the treatment of T1a renal carcinomas. Further studies can be conducted to elucidate the influence of MWA on long-term oncological outcomes. © 2021 John Wiley & Sons LtdItem Evaluation of abdominal computed tomography findings in patients with COVID-19: a multicenter study(Galenos Publishing House, 2023) Onur M.R.; Özbay Y.; İdilman İ.; Karaosmanoğlu A.D.; Ramadan S.U.; Barlık F.; Aydın S.; Odaman H.; Altay C.; Akın I.B.; Dicle O.; Appak Ö.; Gülpınar B.; Erden A.; Kula S.; Çoruh A.G.; Öz D.K.; Kul M.; Uzun Ç.; Karavaş E.; Levent A.; Artaş H.; Eryeşil H.; Solmaz O.; Kaygusuz T.Ö.; Faraşat M.; Kale A.B.; Düzgün F.; Pekindil G.; Apaydın F.D.; Duce M.N.; Balcı Y.; Esen K.; Kahraman A.S.; Karaca L.; Özdemir Z.M.; Kahraman B.; Tosun M.; Nural M.S.; Çamlıdağ İ.; Onar M.A.; Ballı K.; Güler E.; Harman M.; Elmas N.Z.; Öztürk C.; Güngör Ö.; Herek D.; Yağcı A.B.; Erol C.; Şeker M.; İşlek İ.; Can Y.; Aslan S.; Bilgili M.Y.K.; Göncüoğlu A.; Keleş H.; Bekin Sarıkaya P.Z.; Bakır B.; Dağoğlu Kartal M.G.; Durak G.; Oğuzdoğan G.Y.; Alper F.; Yalçın A.; Gürel S.; Alan B.; Gündoğdu E.; Aydın N.; Cansu A.; Kuş C.C.; Tuncer E.O.; Pişkin F.C.; Çolakoğlu Er H.; Değirmenci B.; Özmen M.N.; Kantarcı M.; Karçaaltıncaba M.PURPOSE To evaluate the frequency of abdominal computed tomography (CT) findings in patients with coronavirus disease-2019 (COVID-19) and interrogate the relationship between abdominal CT findings and patient demographic features, clinical findings, and laboratory test results as well as the CT atherosclerosis score in the abdominal aorta. METHODS This study was designed as a multicenter retrospective study. The abdominal CT findings of 1.181 patients with positive abdominal symptoms from 26 tertiary medical centers with a positive polymerase chain-reaction test for severe acute respiratory syndrome coronavirus 2 were reviewed. The frequency of ischemic and non-ischemic CT findings as well as the association between CT findings, clinical features, and abdominal aortic calcific atherosclerosis score (AA-CAS) were recorded. RESULTS Ischemic and non-ischemic abdominal CT findings were detected in 240 (20.3%) and 328 (27.7%) patients, respectively. In 147 patients (12.4%), intra-abdominal malignancy was present. The most frequent ischemic abdominal CT findings were bowel wall thickening (n = 120; 10.2%) and perivascular infiltration (n = 40; 3.4%). As for non-ischemic findings, colitis (n = 91; 7.7%) and small bowel inflammation (n = 73; 6.2%) constituted the most frequent disease processes. The duration of hospital stay was found to be higher in patients with abdominal CT findings than in patients without any positive findings (13.8 ± 13 vs. 10.4 ± 12.8 days, P < 0.001). The frequency of abdominal CT findings was significantly higher in patients who did not survive the infection than in patients who were discharged after recovery (41.7% vs. 27.4%, P < 0.001). Increased AA-CAS was found to be associated with a higher risk of ischemic conditions in abdominal CT examinations. CONCLUSION Abdominal symptoms in patients with COVID-19 are usually associated with positive CT findings. The presence of ischemic findings on CT correlates with poor COVID-19 outcomes. A high AA-CAS is associated with abdominal ischemic findings in patients with COVID-19. © 2023, Galenos Publishing House.

Chest X-rays, which are frequently used in diagnosis, cause ionizing radiation exposure and a loss of time. We aimed to compare the diagnostic accuracy of chest radiography (CR) and lung ultrasonography (US) in patients with LRTIs. Materials and Methods: This study was designed as methodological research. Of the 62 patients evaluated in our study, four refused to participate, and eight were excluded from the study due to their underlying chronic diseases. All 50 remaining patients (between the ages of 0-18 years) were evaluated with a preliminary LRTI diagnosis. Lung US was performed by a 3rd-year pediatric resident who had six hours of online US training. CR was taken after lung US. Results: The mean age of the 50 cases included in this study was five years and three months; 35 of the 50 patients (70%) had a clinical diagnosis of pneumonia, 15 (30%) of them had a clinical diagnosis of bronchiolitis. Statistically significant interobserver agreement was found between US and CR [Kappa value 0.772, 95% confidence interval (0.590-0.925) (p=0.000)]. The sensitivity of lung US was 95%, and its specificity was 85.7% when CR was accepted as the gold standard. Conclusion: Our study demonstrates that lung US can be used instead of CR to diagnose and follow-up pediatric cases with LRTIs. © 2023 Galenos Publishing House.

Material and method: 12 patients who applied to our clinic for erectile dysfunction in the last 1 year and accepted this study were included. Preoperative two-dimensional shear wave elastography imaging was performed in 12 patients and recorded in the Pascal (kPa) unit. Approximately 0.5 × 0.5 × 0.5 cm tissue samples were taken from the right and left cavernous tissue during penile prosthesis implantation operation. Tissue samples were sent to the pathology department. The percentage of the area covered by muscle fibers and elastic fibers in the corpus cavernosum was noted semi-quantitatively (ratio of muscle fibers and cavernous body elastic fiber score). All data obtained were compared with each other. Results: Cavernous body elastic fiber score data(Grouped Score 1, 2 and 3) and percentage of cavernous body muscle fibers data (Grouped %10, %20, %30… %100) were compared with Shear wave elastography data (kPa). The results were not statistically significant according to the Kruskal Wallis Test. Cavernous body elastic fiber score and the percentage of cavernous body muscle fibers were also compared, it was not statistically significant according to the Kruskal Wallis test and Spearman’s correlation test. Conclusions: Penile shear wave elastography can be used clinically to quantitatively assess the amount of smooth muscle cells and elastic fibers in the penis, but it deserves to be studied with a larger number of patients and a more specific interpretation of the pathology preparation. © 2022, Società Italiana di Ultrasonologia in Medicina e Biologia (SIUMB).Item Iatrogenic Iliac Arteriovenous Fistula Presenting with Heart Failure Symptoms After Ruptured Ovarian Cyst Surgery; [Over Kist Rüptürü Operasyonu Sonrası Kalp Yetersizliği Semptomları ile Prezente Olan İyatrojenik İliyak Arteriyovenöz Fistül](Ortadog u Reklam Tanitim Yayincilik Turizm Egitim Insaat Sanayi ve Ticaret A.S., 2023) Alkan F.; Düzgün F.Iatrogenic arteriovenous fistulas (AVF), which are increasing in the literature with the increase of surgical closed vascular interventions in diagnosis and treatment, are rare but have fatal complications. AVF may present with congestive heart failure symptoms, cardio-pulmonary symptoms, and leg edema immediately after the operation or over the years, depending on the size of the fistula. Diagnosis can be made by imaging examinations such as Doppler ultrasonography, computed tomography, or magnetic resonance angiography in patients with suspected AVF. The endovascular stent-grafting approach seems to be more popular in eligible patients due to surgical treatment's high morbidity and mortality rates. We aimed to report a rare case of iliac arteriovenous fistula that developed after a laparoscopic intervention due to ovarian cyst rupture and successfully grafted with an endovascular covered stent. 2146-9032 / Copyright © 2023 by Türkiye Klinikleri.

Early detection of pneumonia is necessary for early treatment to manage and cure the disease. Recently, machine learning-based pneumonia detection methods have focused on pneumonia in adults. Machine learning relies on manual feature engineering, whereas deep learning can automatically detect and extract features from data. This study proposes a deep learning feature extraction-based hybrid approach that combines deep learning and machine learning to detect pediatric pneumonia, which is difficult to standardize. The proposed hybrid approach enhances the accuracy of detecting pediatric pneumonia and simplifies the approach by eliminating the requirement for advanced feature extraction. The experiments indicate that the hybrid approach using a Medium Neural Network based on AlexNet feature extraction achieved a 97.9% accuracy rate and 98.0% sensitivity rate. The results show that the proposed approach achieved higher accuracy rates than state-of-the-art approaches. © Australasian College of Physical Scientists and Engineers in Medicine 2023.Item Our Single Center Experience in Osteoid Osteoma Patients Treated with CTGuided Percutaneous Radiofrequency Ablation Treatment and Follow-up(2024) Düzgün F.; Tosyalı H.K.; Tarhan S.Introduction: Osteoid osteoma (OO) is a painful benign bone tumor. Typically, it causes pain that is most noticeable during the night, which is improved by nonsteroidal anti-inflammatory drugs. In the treatment of symptomatic lesions, open surgery for nidus removal is the gold standard. However, surgical technical difficulties and morbidities vary by location. Percutaneous radiofrequency ablation (RFA) therapy guided by computed tomography (CT) is now a popular treatment option for OO. This study aims to assess our single-center experience with the technique, complications, and procedure effectiveness. Materials and Methods: The study included fifteen patients who were treated between 2017 and 2021. A retrospective analysis was carried out on archive images and file records. The lesions' location, nidus width, and affected area (cortical, medullary) were all recorded. The procedure and technical success, as well as postoperative complications and the need for repeat ablation, were all documented. Results: A total of 20 patients, 18 men, and 2 women, were included in the study, and 12 of them were pediatric patients. The patients' mean age was 16.9±7.3 years old, and the mean nidus diameter was 7.1±8.7 mm. There were 13 cortical niduses, 2 intramedullary niduses, and 5 corticomedullary niduses. The lesions were in the femur (n=12), tibia (n=6), scapula (n=1), and vertebrae (n=1). Two recurrences (10%) were observed in our patients during the follow-up. Patient with a femoral OO, the pain started again 12 weeks after the procedure and we performed additional RFA. The patient with vertebral OO had fewer symptoms and full recovery was not achieved. Therefore, the vertebral OO was ablated again 4 months later, and clinical success was achieved. One patient had a minor burn at the entry site that went away on its own after a short period of time. Except for the patient who was scheduled for a repeat RFA, no recurrence has been observed so far. The primary and secondary success rates are, respectively, 90% (18/20) and 100% (20/20). Conclusion: RFA has a high success rate in treating OO. The procedure failure and recurrence rates are low. There are possibilities for posttreatment pain relief, early discharge, and a quick return to daily life. For inappropriate lesion localization, the RFA process replaces surgical treatment. The procedurerelated complication rate is low. On the other hand, the burn during the procedure can be a serious problem.
