Welcome back to Roshcast Episode 33! This episode marks an incredible milestone for Roshcast. Exactly 365 days ago, Roshcast was born (Apgars 7 and 9). It is wild to look back and think about how much we have covered – hundreds of questions, thousands of pearls, dozens of test-taking strategies, regular tweets, etc.
We couldn’t be more excited about where Roshcast has been or where it is going. In honor of hitting one year, we are doing another trauma ring tone competition. During episodes 34 to 38, listen for a trauma ring tone, and tweet the exact time to us or e-mail the time to us. A few weeks ago, we also launched a new partnership with the EM Clerkship podcast as a core EM corollary for selected topics. This week, we are doing another crossover episode, in which we return to cardiac arrhythmias — specifically, bradycardia. Let’s get the episode started with a rapid review of some essential vitamins, which were recently covered on the Rosh Blog.
* The fat-soluble vitamins are A, D, E, and K.* Vitamin D deficiency can lead to rickets in children and osteomalacia in adults. Vitamin D deficiency is classical seen in the elderly, those with insufficient sun exposure, malnutrition, malabsorption, breastfeeding infants, and those who take anticonvulsants.* Vitamin E deficiency can present with areflexia, peripheral neuropathy, gait abnormalities, ophthalmoplegia, and decreased proprioception.* Vitamin A deficiency is associated with night blindness, xerosis (dryness of the skin, mucous membranes, and conjunctiva), as well as Bitot’s spots (white patches on the conjunctiva).
