Article Citation - Scopus: 1Ocular Flutter-Myoclonus-Ataxia Syndrome After mRNA BNT162b2 COVID-19 Vaccine: A Case Report(Turkish Neuropsychiatric Society, 2022) Poyraz, T.; Varol, A.; Uysal, Armağan; Uysal, Hasan ArmağanOcular flutter (OF) is a rare oculomotor syndrome. The most common etiologies are paraneoplastic, postinfectious and toxic-metabolic. However post-vaccinal etiology was rarely reported in OF. Here, we reported a post-vaccinal clinical syndrome characterized by OF-myoclonus and ataxia associated with oligoclonal bands (OCBs). A 60-year-old male who presented with dizziness, unsteady gait, involuntary movements, involuntary conjugate eye oscillations and extremity jerks that started 3 days after the second dose of mRNA BNT162b2 Covid-19 vaccine. Routine biochemical and serological analysis were within normal limits. No pathological finding was detected in brain MRI. Paraneoplastic and autoimmune encephalitis tests were unremarkable in cerebrospinal fluid (CSF). Oligoclonal bands were positive in CSF. This is the first description of the relationship between vaccines against SARS-CoV-2 and the clinical syndrome of OF, Myoclonus and Ataxia (OFMAS). Humoral immune mechanisms seem to play an important role in OFMAS. Presence of OCBs in CSF may also be associated with this condition. © 2022 by Turkish Association of Neuropsychiatry.Article Citation - WoS: 1Citation - Scopus: 1Comparison of Facial Palsy Cases Before and During the Pandemic Coronavirus Disease-2019(Galenos Publ House, 2023-06-23) Uysal, Hasan Armağan; Güllüoğlu, HalilObjective: The pandemic coronavirus disease-2019 (COVID-19) is caused by a novel type of coronavirus named severe acute respiratory syndrome coronavirus-2 and is rapidly spreading all over the world. In addition to various neurological symptoms, acute facial palsy was diagnosed as the main neurological symptom in some COVID-19 patients. The current study aimed to analyze the variation and any possible association in the case numbers or medical symptoms of patients with facial palsy before and during the COVID-19 pandemic.Methods: The clinical files of patients who were diagnosed with facial palsy in the Neurology Department of Medicalpoint Hospital, University of Economics Faculty of Medicine, Izmir were retrospectively investigated. To compare the facial palsy cases according to different periods, two patient groups were formed: before the COVID-19 pandemic and during the COVID-19 pandemic. The pandemic group was further divided into two subgroups as COVID-19-positive and COVID-19-negative patients to compare the effects of COVID-19 on facial palsy.Results: During the specified COVID-19 period (May 2020-January 2021) of the study, 38 patients were admitted to the hospital for facial palsy; 34 facial palsy patients were admitted in the same calendar period as the two previous years (May 2018-January 2019). There was no significant difference in the frequency of facial palsy between these two time periods. There were significant differences between before and during the COVID-19 pandemic groups regarding response to cortisone therapy (p<0.001), facial palsy grade (p<0.001), electromyography findings (p=0.005), denervation (p<0.001), and 6 months recovery (p<0.001) data. There were also significant differences between the COVID-19-positive and COVID-19-negative subgroups regarding response to cortisone therapy (p=0.015) and facial palsy grade (p=0.001).Conclusion: The current study findings support the possible association between the severity of the clinical course of facial palsy and COVID-19. Further studies are needed to prove a direct association between facial palsy and COVID-19.Article Citation - WoS: 2Citation - Scopus: 2Analysis of Nucleotide Changes in Rt-Pcr Primer/Probe Binding Regions in Sars-Cov Isolates Reported From Turkey(Ankara Microbiology Soc, 2021-07-16) Demir, Ayse Banu; Bulgurcu, Alihan; Appak, Ozgur; Sayiner, Ayca ArzuThe SARS-CoV-2 virus, which caused the COVID-19 epidemic, caused more than 55 million cases and nearly 1.5 million deaths worldwide. For the microbiological diagnosis of the disease, the most valid method is detecting the presence of the viral genome by real-time reverse transcription polymerase chain reaction (rRT-PCR). However, due to the nature of the RNA viruses, frequent mutations may affect the sensitivity of the analyses made on the genetic material of the virus, such as PCR. In this study, we aimed to investigate the mutations in the primer-probe binding regions of the rRT-PCR panels used in COVID-19 diagnosis. SARS-CoV-2 whole genome sequence data (n= 194) isolated from COVID-19 cases in Turkey and uploaded on GISAID database from the centers in Istanbul (n= 78), Ankara (n= 58), Kars (n= 47), Bursa (n= 2), Adiyaman (n= 2), Erciyes (n= 1) and Kocaeli (n= 1) between March 17-September 14, 2020 were analyzed. In order to determine the nucleotide changes, SARS-CoV-2 sequences from Turkey were compared to the reference genome sequence (NC_045512.1) present in GenBank website. The constructed data set was aligned using the MAFFT program and was checked manually if the sequences were in the same frame by using the AliView program. Primer-probe binding sites of the thirteen SARS-CoV-2 rRT-PCR panels from seven different institutes (US CDC, China CDC, Charite CDC, Pasteur, HKU, Thailand, NIID) that are being used in COVID-19 diagnosis were evaluated in terms of nucleotide changes within the corresponding regions compared to the reference genome. Sequence diversities in the viral genomes were determined via positional nucleotide numerical calculator and entropy calculator modules and nucleotide and entropy changes in primer-probe binding regions for each rRT-PCR panel were examined. Among thirteen different primer-probe panels, nucleotide changes in the target regions of the seven primer-probe panels were determined. When viral sequences with nucleotide changes in the primer-probe binding regions were examined, the most common changes were observed in the China CDC N-forward primer and US CDC N3-forward primer binding regions. It is important that the kits to be used as diagnostic tests are designed specific to the regions with less nucleotide changes. Nucleotide changes may not be critical for DNA amplification for most PCR panels, but should be carefully monitored as they may affect the sensitivity of the assay. If the risk of alteration of the designed region is high, the primer - probe binding sites should be checked frequently and updated when necessary.Article Possible Therapeutic Role of Cholinergic Agonists on Covid-19 Related Inflammatory Response(Dokuz Eylul Univ Inst Health Sciences, 2021-02-26) Baris, Elif; Arici, M. AylinSevere acute respiratory syndrome-corona virus-2 (SARS-CoV-2) or coronavirus infectious disease (COVID-19) outbreak is continued to spread all over the world recently with the high mortality and morbidity rates. It is also known well COVID-19 is leading causes of acute lung injury and acute respiratory distress syndrome (ARDS), sepsis and multiorgan failure. Current treatment of COVID-19, includes different strategies targeting preventing viral replication or treating secondary infections and decreasing exaggerated immune response. Although antiviral, antimicrobial, immunomodulatory agents including anti-cytokines and glucocorticoids have been currently applied, there is lack of a specific treatment for COVID-19. In this review, possible therapeutic roles of cholinomimetic drugs in the control of COVID-19 related inflammation is discussed.
