The first COVID-19 case in our country was detected on 11 March 2020. Failure to develop a vaccine against COVID-19 disease and the situation in the world required both hospitals and health policymakers to take measures for the possible continuity of the disease. 1 COVID-19 pandemic threatens the health systems of many countries. 2 Of course, healthcare professionals are the most affected by this pandemic. During this period, they faced a threat that had not been encountered before and had to manage a difficult situation both physically and psychologically. 3 Research into the psychological effects of infectious disease outbreaks such as severe acute respiratory syndrome (SARS) and pandemic flu (H1N1) shows consistent patterns of reactions and covers the experiences of the staff in work, those in quarantine and those returning to work from time away sick. 4,5 In the case of a pandemic, the staff do not only deal with the increased workload created by the outbreak. At the same time, fear of transmission for themselves and their families, new and frequently changing protocols, working with personal protective equipment, caring for very sick and rapidly deteriorating patients, and dealing with colleagues who are sick are among the other problems.During this period, the employees in all health institutions and organisations, both in the hospitals and primary care, took part in the pandemic management and continue to do so. When the literature is reviewed, the importance of strong primary care and family physicians in the management of pandemics is emphasised in the publications. It is stated that the primary care must be included in the planning and action stages in health-related emergency and risk management. 6,7 Front-line primary care leaders, practitioners and researchers of primary care from the South Asia Region have issued a solidarity statement articulating the role of primary care physicians during the pandemic. They stated that the specific roles in mitigating the pandemic include triage, fever screening, handling

ÖZET GİRİŞ ve AMAÇ: Transkranial B-mod sonografi ile kranium ve içindeki anatomik belirteçlerin tespit edilmesi ile transkranial orta serebral arter (MCA) renkli Doppler insonasyon başarısı ve kalitesi belirlenebilir. Bu muayenede pratik kazanımlar getirebilir. YÖNTEM ve GEREÇLER: 375 (Kadın: 217, yaş: 64±9 yıl) 50 yaş üzerinde ve görünürde nörolojik hastalığı olmayan sağlıklı kontrol olguda transkranial B-mod sonografi ve transkranial renkli Doppler ultrasonografi yapılmıştır. Kontralateral temporal kemik ("CTB"), mezensefalon ("MB") ve ipsilateral sphenoid kemik küçük kanadın ("LSW") sonic görüntülenebilme kalitesi Suzuki sınıflaması ile belirlenmiş ve bunun MCA Doppler sinyali kaydedilebilmesi için diagnostic özellikleri saptanmıştır. BULGULAR: Bir tarafta MCA Doppler sinyali kaydedilememesi %4,6 (%95 GA: 3,2%-6.4%) olup kadınlarda anlamlı olarak fazladır (kadın: %11,1 ve erkek: %0,6). MCA Doppler sinyali elde edilememesi için B-modda MB'nin hiç görülememesinin duyarlığı (%95 güven aralığının alt limiti) %87, özgüllüğü %99; LSW hiç seçilemesinin duyarlığı %80 ve özgüllüğü %93; CTB hiç görüntülenememesinin duyarlılığı %29 ve özgüllüğü %99,5; CTB'nin yarısından azı görülmüş ise duyarlılık %89,5 ve özgüllük %99,5'dir. TARTIŞMA ve SONUÇ: B mod sonografi ile transtemporal akustik pencerenin MCA Doppler incelemesi için yetersizliği kolayca belirlenebilir. Kontralateral temporal kemiğin görüntülenemesi mezensefalon ve ipsilateral sphenoid kemik küçük kanadın görüntülenememesinden daha yol gösterici olabilir.

ABSTRACT INTRODUCTION:The success and quality of transcranial color Doppler insonation of the middle cerebral artery (MCA) can be determined by visualization of craniocerebral sonoanatomical markers defined by transcranial B-mode sonography. This strategy can bring practical gains to the neurosonology examination. METHODS: Transcranial B-mode sonography and transcranial color Doppler ultrasonography were performed in 375 healthy control patients (Female: 217, age: 64 ± 9 years) over 50 years of age with no apparent neurological disease. The quality of sonic imaging of the contralateral temporal bone (CTB), mesencephalon (MB) and ipsilateral sphenoid bone small wing (LSW) was determined by the Suzuki classification, and their diagnostic properties were determined in terms of recordability of the MCA Doppler signal. RESULTS: Failure to record the MCA Doppler signal on at least one side is 4.6% (95% CI: 3.2 -6.4%) and is significantly higher in women (11.1% vs. 0.6%). For failure to receive MCA doppler signal, lower limit of 95% confidence interval of the sensitivity of MB total nonvisualisation in B-mode was 87%, along with specificity of 99%; the sensitivity of LSW sonic _____________________________________________________________________________________________________________________________

127We evaluated the reversible electrophysiologic abnormalities of two cases of hypokalemia paralysis (HypoPP) because of its similar findings in acute motor axonal neuropathy (AMAN). Nerve conduction studies (NCS), repetitive nerve stimulation, and exercise tests were performed in both patients. Adding a 15 minuteexercise test to routine NCS may help distinguish AMAN from HypoPP.
