CME Experience!
Hello, Dermasphere listeners! I’m gathering some colleagues to participate in a FREE small-group, online social learning experience! It's about chronic spontaneous urticaria. It's free, accredited (earn 7.25 AMA CME/CE credits), brief, non-branded, valuable (current modules and patient cases), and flexible in time commitment. In addition to independently completing the short modules and cases, our cohort will meet online via Zoom for discussions to exchange insights: We meet once at the beginning and then several times throughout the year to review updates from major conferences! Sign up here:

Looking forward to learning with you!
