    Ionizing radiation exposure in patients with covid-19: more than needed
    (Oxford Academic, 2021) Yurdaışık, Işıl; Nurili, Fuat; Aksoy, Süleyman Hilmi; Ağırman, Ayşe Gül; Aktan, Ahmet
    Objective: The aim of the study was to evaluate the ionizing radiation exposure in patients with Coronavirus disease 2019 (COVID-19). Materials and methods: This was a retrospective study in which all patients presented with suggestive symptoms of COVID-19 were included. The study was carried out in a university-affiliated private hospital in Istanbul, Turkey. Biological radiation dose exposure (cumulative effective dose: CED) was evaluated in millisievert (mSv) units. Results: A total of 1410 patients were included in the study. Of all study subjects, 804 patients (57%) underwent only one chest computed tomography (CT) procedure. Six hundred and six patients (43%) had two or more chest CT procedures. Median CED was 6.02 (min-max:1.67-16.27) mSv. The number of patients who were exposed to ? 5 mSv were 149 (24.6%), whereas 457 patients (75.4%) were exposed to >5 mSv. Conclusion: The radiation exposure in COVID-19 patients seems unjustifiably high. Awareness should be increased as to the proper use of chest CT in COVID-19 as per to the society recommendations.

    The relationship between lesion density change in chest computed tomography and clinical improvement in COVID-19 patients
    (WILEY, 2021) Yurdaışık, Işıl; Nurili, Fuat; Ağırman, Ayşe Gül; Aksoy, Süleyman Hilmi
    ABSTRACT Objective: To evaluate the association of changes in chest computed tomography (CT) lesion densities with clinical improvement in COVID-19 patients. Methods: This was a cross-sectional analysis of hospitalized COVID-19 patients who underwent repeated chest CT. Patients who improved clinically but showed radiological progression were included. Demographic data, presentation complaints, and laboratory results were retrieved from the electronic database of the hospital. Lesion density that was measured in Hounsfield Units (HU) was compred between admission and discharge chest CT scans. Results: Forty patients (21males, mean age 47.4±15.1 years) were included in the analysis. The median white blood cell count and CRP significantly decreased, whereas the median lymphocyte count significantly increased at discharge compared with the admission values. The mean density significantly reduced from admission to discharge. Conclusion: This is the first study in the literature reporting reduction in chest CT lesion densities correlated with clinical and laboratory improvement in COVID-19 patients.

    Retrospective analysis of the first 50 emergency/elective surgical cases in terms of mortality and morbidity in CoVid-19 Pandemic Hospital in Istanbul
    (EDIZIONI LUIGI POZZI, 2020) Pekşen, Çağhan; Aktokmakyan, Talar Vartanoğlu; Savaş, Osman Anıl; Datlı, Aslı; Nurili, Fuat; Yurdaışık, Işıl; Bozkurtgil, Neşet; Yavuz, Fatime; Sümer, Aziz
    2019-nCoV currently named SARS-CoV-2 is a highly pathogenic Coronavirus identified in Wuhan China in December 2019. Turkey declared the first case relatively late compared to Asian and European countries on March 11, as the first SARS-CoV-2 infection in Turkey. In this study, we aimed to determine patients' outcomes in 50 surgeries done in the incubation period of SARS-CoV-2 in our hospital. METHODS: We retrospectively analyzed the clinical data of 50 patients who underwent surgeries during the incubation period of CoVid-19 at Istinye University Gaziosmanpasa Medical Park Hospital in Istanbul, from March 2 to April 11, 2020. RESULTS: The age of 50 patients range was 21 to 73, and the median age was 43.32 (64%) patients were women. The median length of hospital stay is 2.6 days (1-21). Operations at various difficulty levels were also performed on patients with co-morbidities. No complication or mortality was observed except for 1 patient, and the ICU requirement of that patient was also due to high energy trauma. CONCLUSION: Although contrary claims have been made in various studies; it is the primary duty of us surgeons to operate CoVid-19 positive/suspicious patients safely and without any contamination, and on the other hand, to continue their operations without victimizing negative patients. In this pilot study, we would like to emphasize with necessary and adequate measures these can be achieved.
