Turkish Journal of Medical Sciences

Background/aim: To better optimize the inactivated vaccine-induced immune response and improve vaccine protection efficiency, a preliminary study was conducted on the influencing factors of producing neutralizing antibody (NAb) titers against the inactivated coronavirus disease 2019 (COVID-19) vaccine. Materials and methods: A total of 91 health care volunteers were enrolled from the Immunology Division of the Laboratory Department of Chongqing General Hospital from February to March 2021. The study had a cross-sectional design. All of the volunteers were scheduled to receive a complete dose regimen of the inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine and the vaccination interval between …

Turkish Journal of Medical Sciences

Background/aim: Children with coronavirus disease 2019 (COVID-19) present milder symptoms than adults and are at lower risk of hospitalization and life-threatening complications. However, the kinetics of lymphocyte subsets and serum immunoglobulins in the peripheral blood during COVID-19 infection remains unclear. In this study, it was aimed to determine the changes in hematological and immunological parameters, especially in the lymphocyte subsets, in the peripheral blood of children with different COVID-19 disease severity. Materials and methods: The study was planned as a prospective cohort and included 68 children aged 0?18 years who were admitted to Ege University Faculty of Medicine Department of …


Which Sequence Should Be Used In The Thorax Magnetic Resonance Imaging Of Covid-19: A Comparative Study, Ayşe Şule Ateş, Burak Yağdiran, Onur Taydaş, Ömer Faruk Ateş Oct 2023

Which Sequence Should Be Used In The Thorax Magnetic Resonance Imaging Of Covid-19: A Comparative Study, Ayşe Şule Ateş, Burak Yağdiran, Onur Taydaş, Ömer Faruk Ateş

Turkish Journal of Medical Sciences

Background and aim: To evaluate and compare magnetic resonance imaging (MRI) sequences that could potentially be used in the diagnosis of coronavirus disease 2019 (COVID-19). Materials and methods: Included in the study were 42 patient who underwent thorax computed tomography (CT) for COVID-19 pneumonia and thorax MRI for any reason within 24 h after CT. The T2-weighted fast spin echo periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) (T2W-FSE-P), fast imaging employing steady-state acquisition, T2 fat-saturated FSE, axial T1 liver acquisition with volume acceleration (LAVA) and single-shot FSE images were compared in terms of their ability to show COVID-19 …


Postauricular Linear Basal Cell Carcinomas Related To Medical Mask Cords: A Possible Association, Bengü Ni̇sa Akay, Di̇lan Kizilirmak, Aylin Heper Oct 2023

Postauricular Linear Basal Cell Carcinomas Related To Medical Mask Cords: A Possible Association, Bengü Ni̇sa Akay, Di̇lan Kizilirmak, Aylin Heper

Turkish Journal of Medical Sciences

Linear basal cell carcinoma (BCC) is a distinct clinical morphological variant of BCC. Although it has been speculated that trauma and the Koebner phenomenon may be linked to linear BCC, the pathophysiology has not yet been shown. Herein, 5 cases of BCC were presented that developed in the postauricular region as a result of trauma caused by the cords of the medical face masks worn during the COVID-19 pandemic.
