Observational StudyImaging Patterns of Encephalopathy in Patients with COVID-19.
The aim of this retrospective observational study was to describe the neuroimaging manifestations of patients with COVID-19. This study was conducted at Aga Khan University Hospital, Karachi, Pakistan from March to July 2020. COVID-19 patients with neurological symptoms and positive neuroimaging were included after confirmation of COVID-19 by polymerase chain reaction test (PCR). ⋯ Three cases had acute watershed infarcts (25%), two cases had posterior cerebral artery territorial infarcts (16.7%), two cases had periventricular corona radiata infarcts (16.7%), three cases had hypoxic ischemic encephalopathy (25%), two cases had posterior reversible encephalopathy syndrome (16.7%), and there was one case each of cerebral venous sinus thrombosis, pontine infarct, and bithalamic lesions (8.3%). This study highlights the diagnostic approaches in COVID-19-associated encephalopathy and the variable imaging features that clinicians and neuroradiologists should be aware of, as the pandemic progresses. Key Words: COVID-19, Neuroimaging, Encephalopathy, Magnetic resonance imaging, Coronavirus.

Long-term outcomes of ischaemic stroke patients with diabetes in a multi-ethnic cohort in Singapore.
Diabetes increases the risk of ischaemic stroke especially among Asians. This study aims to investigate contemporaneous long-term cardiovascular outcomes of ischaemic stroke patients with diabetes in a multi-ethnic Asian cohort. ⋯ Our study provides quantitative data on the event rates of ischaemic stroke patients with diabetes. These findings provide insights on stroke predictors in a multi-ethnic Asian population, which may have implications in the design of future interventional studies.

We present a case of coronavirus disease 2019 (COVİD-19) re-infection where the time interval between two COVİD-positive episodes is the longest in the literature. A 40-year male patient was admitted to the Emergency Department with complaints of sore throat, cough and diarrhea; and was re-diagnosed as COVİD-19 positive after a virus-free period. He did not have a chronic disease in his anamnesis and used no medication. ⋯ In this case, the time to second COVİD-19 infection was 94 days from the first positive PCR test and 86 days from the complete resolution of symptoms. This is one of the longest COVID-19-free period between two episodes of infection in the literature. Key Words: COVID-19, Recurrence, Re-infection, Recovery.

The COVID-19 pandemic brought abrupt changes when quarantine measures were implemented. Most medical students had distance learning as their main content delivery mode, but in clerkship (fifth and sixth years), in-person activities were maintained under new protocols. These different modes may have affected student mental health. This study examines mental burden and empathy in medical students during the beginning of the COVID-19 pandemic according to the year of attendance. ⋯ We found high levels of mental burden in medical students in the early period of the COVID-19 pandemic, especially in first-year students, who may have fewer resources to deal with stress. Moreover, as they entered college a short time before the pandemic, they were unable to experience academic life fully or create important new social support networks to deal with adversities.

Case ReportsRight to Left Intrapulmonary Shunt in a Case with COVID-19-associated Pneumonia.
ABSTRACT The clinical manifestations of coronavirus disease 2019 (COVID-19)-associated pneumonia show a wide range of variations. It ranges from mild hypoxemia without significant signs of respiratory distress, to rapid clinically deteriorating course with severe hypoxemia. Unexplained severe hypoxemia, associated with platypnea, triggers the possibility of ventilation-perfusion (V/Q) mismatch, ranging from intrapulmonary shunts (IPS) to alveolar dead space ventilation. ⋯ The clinical manifestations combined with nuclear imaging features enabled in making the ultimate diagnosis. The patient's clinical condition improved on appropriate clinical management, using high flow oxygen combined with intravenous steroids and anticoagulants. Key Words: COVID-19, Adult respiratory distress syndrome, Right to left shunt, Lung perfusion scintigraphy, Platypnea.
