    Introduction: Various restrictions due to the coronavirus infection have affected working life globally. People with multiple sclerosis (pwMS) have several difficulties in social life, patient follow-up, and receiving treatments. In this study, we aimed to evaluate the experiences of pwMS during the COVID-19 pandemic. Method: We developed a 50-question survey aiming to determine fears, anxieties, and the problems experienced by patients regarding their diseases and social lives during the COVID-19 pandemic. The questionnaire was released online via the Turkish MS Society website, local MS societies websites, and social media accounts. Only the answers of the patients who filled out the questionnaire completely were evaluated. Results: In total, 6008 patients took the survey, and 3255 of them completed the questionnaire. Among all, 378 patients (11.6\%) were positive for COVID-19. The most common COVID-19-related symptom was fatigue (48.4\%). The routine medical follow-up was interrupted in 61.4\% and the medication was discontinued in 14\% of the patients. Approximately 25\% of the patients reported different symptoms related to relapse activity. The main concern of the patients related to the COVID-19 pandemic was the disruption of the health of the ones they loved. Among all the patients, 4.4\% lost their jobs. Conclusion: Our data showed that the COVID-19 pandemic strongly affected the working lives of pwMS. Also, the pandemic changed the attitudes of patients and neurologists. Therefore, the long-term effects of the COVID-19 pandemic on disease approach, patient follow-up, social conditions, and working life should be monitored.

    CSF Proteomics Identifies Specific and Shared Pathways for Multiple Sclerosis Clinical Subtypes
    (PUBLIC LIBRARY SCIENCE, 2015-01-01) Avsar, Timucin; Durasi, Ilknur Melis; Uygunoglu, Ugur; Tutuncu, Melih; Demirci, Nuri Onat; Saip, Sabahattin; Sezerman, O. Ugur; Siva, Aksel; Turanli, Eda Tahir
    Multiple sclerosis (MS) is an immune-mediated, neuro-inflammatory, demyelinating and neurodegenerative disease of the central nervous system (CNS) with a heterogeneous clinical presentation and course. There is a remarkable phenotypic heterogeneity in MS, and the molecular mechanisms underlying it remain unknown. We aimed to investigate further the etiopathogenesis related molecular pathways in subclinical types of MS using proteomic and bioinformatics approaches in cerebrospinal fluids of patients with clinically isolated syndrome, relapsing remitting MS and progressive MS (n=179). Comparison of disease groups with controls revealed a total of 151 proteins that are differentially expressed in clinically different MS subtypes. KEGG analysis using PANOGA tool revealed the disease related pathways including aldosterone-regulated sodium reabsorption (p=8.02x10(-5)) which is important in the immune cell migration, renin-angiotensin (p=6.88x10(-5)) system that induces Th17 dependent immunity, notch signaling (p=1.83x10(-10)) pathway indicating the activated remyelination and vitamin digestion and absorption pathways (p=1.73x10(-5)). An emerging theme from our studies is that whilst all MS clinical forms share common biological pathways, there are also clinical subtypes specific and pathophysiology related pathways which may have further therapeutic implications.

    Comparative study of video-assisted thoracoscopic surgery versus open thymectomy for thymoma and myasthenia gravis

    Introduction: Thymectomy is the preferred standard treatment in younger non-thymoma patients with myasthenia gravis as well as in patients with early stage thymoma. Total thymectomy by median sternotomy has been the surgical approach since resection of the thymus with video-assisted thoracoscopic surgery (VATS). Aim: To compare the clinical outcomes of VATS thymectomy with conventional open thymectomy for neoplastic and non-neoplastic thymic diseases. Material and methods: Forty patients underwent thymectomy between October 2012 and January 2016. Fifteen patients were male and 25 patients were female. The mean age was 40.3 +/- 17.7 years. Seventeen (55\%) patients underwent VATS thymectomy and 23 (45\%) patients underwent an open procedure. We retrospectively reviewed the data of the patients and compared these two techniques. Results: The mean tumor size was 5.17 +/- 3.2 cm in the thymoma group (VATS 2.5 +/- 2.4 cm vs. open access 4.7 +/- 3.7 cm). None of the patients experienced a myasthenic crisis. Conversion to thoracotomy was required in 1 patient in the VATS group due to bleeding from the right internal mammary artery
