I've been using the excellent free medical sharing app Figure 1 for quite some time now. Recently I applied and got chosen to be a student ambassador for the app. The app works similar to Instagram, just for medical images. As a former EMT and current PA student, I think it is a great learning tool for students like myself, and a great platform for seeing and discussing interesting and rare cases. You can download it here http://download.figure1.com/summer2015?m=NYCPA-S.
Enjoy!
