Online Learning > Med Tox Online > Toxicology Visual Pearls


The Toxicology Visual Pearls series is a collaboration between ACMT and ALiEM. The pearls are open-access, expert peer-reviewed, toxicology-related visual stimuli followed by a question and discussion. The authors and editors volunteer their time and expertise to bring this well-regarded series to readers of the ALiEM blog. The series is led by Drs. Louise Kao and Bryan Judge from ACMT and Dr. Michelle Lin from ALiEM.
If you are interested in submitting a pearl for the series please see the submission guidelines below. Also, take a look at the New Author Guide.
