    Influenza viruses and SARS-CoV-2 in adult: 'Similarities and differences'
    (2021) Torun, Serife; Kesim, Cagri; Suner, Aynur; Botan Yildirim, Berna; Ozen, Ozgur; Akcay, Sule; 0000-0002-8964-291X; 0000-0001-7122-4130; 0000-0001-7730-1379; 34957739; AAD-5996-2021; AAN-1681-2021
    Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causing a global pandemic starting from December 2019, showed a course that resulted in serious mortality in the world. In order to understand SARSCoV-2 better, here we aimed to compare the similar and different characteristics of Influenza viruses occurring in the same season with SARS-CoV-2. Materials and Methods: A total of 144 patients (31 patients with COVID-19, 62 patients with H1N1 influenza, and 51 patients with influenza B) were included in the study. Demographic findings, chronic diseases, laboratory values, chest x-ray, and chest CT findings of the patients were evaluated retrospectively. Results: Median age of the COVID-19 patients and rate of male patients were higher than other patient groups (55 years; p< 0.001) (61% male; p< 0.001). The most common chronic medical conditions were hypertension and diabetes. Platelet numbers and alanine aminotransferase values were significantly higher in COVID-19 patients. Radiologically, bilateral (74.2%) and nonspecific distribution (58.1%), ground-glass opacities with consolidation (51.6%), patchy image (25.8%), ground-glass opacities with interstitial changes (22.6%) and halo sign (22.6%) were quite evident than other groups in COVID-19 patients (p< 0.05). Conclusion: We suggest that due to the higher PLT values observed in COVID-19 patients, initiation of anticoagulant therapy should be considered in the early stage and routine follow-up with d-dimer and fibrinogen should be applied for suspected patients. Moreover, attention should be paid in terms of possible liver toxicity of the drugs to be used in treatment due the higher ALT values observed in COVID-19 patients. Since we did not detect SARS-CoV-2 and influenza viruses concurrently in the same patient, it may be helpful to focus on only one virus in a patient with symptoms, and radiographic differences can be used to differentiate COVID-19 from influenza.

    Can unenhanced brain magnetic resonance imaging be used in routine follow up of meningiomas to avoid gadolinium deposition in brain?
    (2019) Rahatli, Feride Kural; Donmez, Fuldem Yildirim; Kesim, Cagri; Haberal, kema Murat; Turnaoglu, Hale; Agildere, Ahmet Muhtesem; 0000-0002-8211-4065; 0000-0002-8964-291X; 30343167; R-9398-2019; AAB-5802-2020; AAD-5996-2021; AAE-5528-2021
    Purpose: We hypothesized that unenhanced brain MRI can be used in follow up of patients with intracranial meningioma to avoid gadolinium deposition in the brain and allow measurement of meningioma dimensions from pre-contrast T2-weighted images. Methods: Dimensions of meningiomas were measured on pre-contrast T2, post-contrast T1 weighted images. Results: The sizes of meningiomas in post-contrast axial T1-weighted images were similar with that in pre-contrast axial T2-weighted images. Signal intensity increase was detected in dentate nucleus and globus pallidus (P < 0.05). Conclusion: Gadolinium deposition could be avoided in patients with meningioma by using unenhanced brain MRI for follow up scans.
