    Effectiveness of magnetic resonance angiography in the evaluation of lung perfusion in constrictive bronchiolitis obliterans
    (Wiley-Blackwell Publishing, Inc, 2009) Yilmaz, Ozge; Savas, Recep; Sogut, Ayhan; Ozkol, Mine; Yuksel, Hasan
    Childhood constrictive bronchiolitis obliterans (CBO) is characterized clinically by the persistence of obstructive respiratory symptoms following a prolonged episode of lower respiratory viral infection. The diagnosis depends on the clinical, radiological and laboratory findings. Perfusion defects on scintigraphy may predict the severity. This report describes a 2-year-old girl who presented with a 15-day history of respiratory distress despite treatment. Auscultation of the lungs revealed prolonged expiration and bilateral crepitant rales. CXR revealed bilateral paracardiac infiltration. She improved with a treatment regimen of bronchodilators, systemic steroids and antibiotherapy; however, rales were detected again 10 days after discharge. HRCT of the lung revealed an oligaemic-mosaic pattern, more prominent in the left lung. The diagnosis of CBO was made on the basis of these clinical and radiological findings. Perfusion was normal in the right lung but diffusely decreased in the left lung on perfusion scintigraphy by Tc99m-MAA. Magnetic resonance (MR) angiography source images of the lungs revealed significant but not diffuse perfusion defects in the left lung, in contrast to radionuclide scintigraphy. There were areas of low perfusion in the right lung, which were not evident in radionuclide scintigraphy. The use of source images of MRI angiography of the lungs may be more sensitive and specific for the detection of perfusion defects in patients with CBO and may assist in determining the prognosis.

    A mass screening survey of cystic echinococcosis by ultrasonography, Western blotting, and ELISA among university students in Manisa, Turkey
    (Elsevier Science Bv, 2013) Kilimcioglu, Ali Ahmet; Girginkardesler, Nogay; Korkmaz, Metin; Ozkol, Mine; Duzgun, Fatih; Ostan, Ipek; Pabuscu, Yuksel; Dinc, Gonul; Ok, Ulgen Zeki
    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.

    Prediction of neurodevelopmental outcome in term neonates with hypoxic-ischemic encephalopathy
    (Elsevier Sci Ltd, 2013) Polat, Muzaffer; Simsek, Ayse; Tansug, Nermin; Sezer, Rabia G.; Ozkol, Mine; Baspinar, Pinar; Tekgul, Hasan
    Background: Hypoxic ischemic encephalopathy may result in many neurological deficits. It is crucial to make early diagnosis and assess the prognosis correctly. Aims: We aimed to determine the factors to evaluate the prognosis of hypoxic ischemic encephalopathy. Methods: Electroencephalography, neuroimaging, periodic neurological exams and a developmental test at 44-48 months after discharge from the hospital were performed on twenty five term newborn infants with clinical evidence of hypoxic ischemic encephalopathy. Results: Normal/mildly abnormal neonatal electroencephalography correlated with favorable outcome, particularly if neuroimaging was normal. The cranial MRI sensitivity was 83.3%, while the specificity was 57.9%, the positive predictive value was 38.5%, and the negative predictive value was 91.6%. Moderate/severely abnormal electroencephalography and multifocaVdiffuse cortical or deep gray matter lesions correlated with poor outcome. Conclusions: Newborn infants with hypoxic ischemic encephalopathy should be treated in neonatal intensive care units, assessed with periodic neurological examination, electroencephalogram and brain imaging. This would help to initiate early intervention and improve the outcome of patients. (C) 2012 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

    A province-based study using sampling method to investigate the prevalence of cystic echinococcosis among primary school children in Manisa, Turkey
    (Elsevier Science Bv, 2007) Ok, Ulgen Z.; Ozkol, Mine; Kilimcioglu, Ali A.; Dinc, Goenuel; Bayindir, Petek; Ostan, Ipek; Pabuscu, Yueksel; Ozcan, Cemil; Korkmaz, Metin; Coskun, Senol; Yuksel, Hasan; Girginkardesler, Nogay
    A province-based field study using a portable ultrasound scanner (US) was performed for the first time using sampling method to investigate the prevalence of cystic echinococcosis (CE) in primary school children in Manisa, Turkey. A total of 6093 children from 37 primary schools was selected as the representative sample of the total number of 166,766 primary school children, and examined by the US. Prevalence was found to be 0.15%, as nine children were diagnosed with CE, seven new and two previously operated. A questionnaire applied to the children revealed no significant relationship between the risk factors and the infection (P > 0.05). In conclusion, it would be advisable to repeat the study at the same schools in eight years' time, in order to evaluate the efficacy of the control programs, since nearly all students involved in this study will have graduated by then. Besides, it is recommended to choose a sampling group to find the prevalence of an infection in a defined region. (c) 2007 Elsevier B.V. All rights reserved.
