AbstractNitrous oxide is used medically as an anesthetic agent; in the food industry as a propellant for condiments; and recreationally for its euphoric and dissociative effects. We report three cases of nitrous oxide misuse causing severe, symptomatic cobalamin (vitamin B12) deficiency in which signs of nitrous oxide use per se, as well as signs of toxicity, were observed, including characteristic palmar calluses over the metacarpal heads, and frostbite. These signs may assist clinicians in the recognition of nitrous oxide use and the timely diagnosis of nitrous oxide toxicity. [ABSTRACT FROM AUTHOR]
