Quizzes are fun. I usually can't pass them up. So, every once in a while, I make up my own quiz to let readers find out what they know about this important topic.
CAD is the acronym for cervical acceleration/deceleration, a.k.a. whiplash. But this time I thought it might be fun to provide a little incentive, especially since it is the holiday season. So here's the deal: I'm making the quiz somewhat challenging, and the answers will be posted on my website ([url=http://www.srisd.com]http://www.srisd.com[/url]). After the contest is over, which will be exactly two weeks after this issue is published. The highest score wins. In the case of a perfect score or tie, the earliest post gets the victory. Answers should be posted to my website. The prize is a $150 gift certificate toward any of the products or services listed on the website. Good luck.

Many relevant diagnostic signs are not performed deliberately by the examiner or by the patient at the examiner’s direction. They are observed as the patient reacts to their condition. Fortin’s finger sign, Minor’s sign, and Vanzetti’s sign are three examples of this principle.
Spearheaded by burgeoning scientific and clinical research literature, psychedelics have reached a level of media coverage and popular interest that has not been seen for over half a century. By “psychedelics,” we are referring to the unique class of substances that includes psilocybin (the active compound found in so-called “magic mushrooms”), LSD, dimethyltryptamine (DMT), ayahuasca, 5-MeO-DMT, and mescaline – each of which occurs in the natural world (except for LSD, which is a semi-synthetic compound).
While working at the Lovelace Medical Center in Albuquerque, N.M., one of the primary care physicians stated that imaging every patient prior to receiving chiropractic was not medically necessary. It was at that point I reconsidered the need for the imaging of every patient to avoid malpractice.
