https://www.selleckchem.com/products/4-chloro-dl-phenylalanine.html Coronavirus disease 2019 (COVID-19) results from infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first reported in Wuhan, China in patients suffering from severe pneumonia and acute respiratory distress syndrome and has now grown into the first pandemic in over 100 years. Patients infected with SARS-CoV-2 develop arterial thrombosis including stroke, myocardial infarction and peripheral arterial thrombosis, all of which result in poor outcomes despite maximal medical, endovascular, and microsurgical treatment compared with non-COVID-19-infected patients. In this review we provide a brief overview of SARS-CoV-2, the infectious agent responsible for the COVID-19 pandemic, and describe the mechanisms responsible for COVID-19-associated coagulopathy. Finally, we discuss the impact of COVID-19 on ischemic stroke, focusing on large vessel occlusion.Supraglottitis is an ear, nose and throat emergency where swelling of the laryngeal structures can threaten to fatally obstruct the airway. Most cases of supraglottitis are of infective origin but other rarer causes have been documented. We present two patients who presented with stridor and were found to have supraglottic oedema on fibreoptic nasolaryngoscopy. Both patients presented with odynophagia and progressive dyspnoea and were initially medically managed to stabilise their airway. This included intravenous steroids, nebulised epinephrine and intravenous antibiotics. After this initial treatment they both required investigation and optimisation of their underlying medical conditions (rheumatoid arthritis with possible systemic lupus erythematosus and nephrotic syndrome) as more definitive management.For patients whose vasculitis is managed with biologic medications, no reports or evidence-based guidance exists regarding the perioperative management of microvascular flaps. We present a case of a 78-year-old patient with T
