Nailfold dermoscopy predicts the absence of a capillaroscopy sclerodermic pattern: The multicentre, prospective VASCUL-R trial.

Background: Nailfold capillaroscopy is recommended to diagnose primary or secondary Raynaud's phenomenon (RP). Capillaroscopy is normal in primary RP, which is the most frequent. Screening for RP capillary anomalies with nailfold dermoscopy has been promising.

Severe arterial thrombosis associated with Covid-19 infection.

• Unlike venous thromboembolism, no data are available on arterial thrombosis in SARS-CoV2 infected patients. • We observed severe arterial thrombotic complications despite the use of antiplatelet or anticoagulant therapy. • We described five irreversible lower limb ischemia and two thoracic aortic free floating thrombi.
