In the January episode of Critical Decisions in Emergency Medicine, Drs. Danya Khoujah and Wendy Chang dive into an emotionally charged topic: child abuse, a public health crisis that crosses all socioeconomic, racial, and ethnic lines. They’ll also unmask the Great Masquerader, infectious endocarditis, to help you identify patients at high risk of this potentially devastating disease, which can lead to irreversible structural damage to the heart and other organ systems. And, as always, you’ll get the 411 on the pressing subjects covered in CDEM’s regular features, including Drug Box and Tox Box.
