A random serving of knowledge food for your brain hole with returning guest, Dr. Alan Dow, Professor of Internal Medicine at Virginia Commonwealth University School of Medicine. Our final live recap show from ACP 2018 covering: human microbiome, copper deficiency, POTS syndrome, substances of abuse, drugs for delirium and how to be more like Leonardo Da Vinci. Please let us know what you liked, didn’t like and how we can make the show better.

Advice
“Don’t be afraid to use your talents to tackle the problems you see before you” -Alan Dow, MD
“Writing is easy. You just open up a vein and bleed.” Ernest Hemingway

Random Pearls
Dr. Dow gave us pearls from 5 lectures that he attended at ACP

The Human Microbiome

  • Fecal Matter Transplant Update: Microbiome research shows that people who get C. Diff have less heterogeneous microbiomes (JC Lagier Hum Microbiome J 2016). Next steps are to show how the microbiome relates to other clinical outcomes and tease out causality vs. association.

Thieves’ Market

  • A Unique Case: The market is a diagnostic case presentation format where people can shout out differential diagnoses as pieces of the case are presented. Patient presented with neuropathy with megaloblastic anemia from copper deficiency induced by zinc toxicity from denture cream. Here’s a case report of zinc-induced copper deficiency, from zinc supplements (J Johnsrud. Perm J 2017)

The Orthostatic Outpatient

  • Postural Orthostatic Tachycardia Syndrome: POTS physiology is similar to that of astronauts’: the left ventricle atrophies about 1% per day such that stroke volume decreases. When the heart has to work against gravity (standing), it must increase heart rate to maintain the same cardiac output.
  • A new name for POTS?! In POTS, the heart is “too small” and might be more aptly named “the Grinch syndrome” (Fu Q et al. JACC 2011)

    Discovered your podcast a few months ago while looking around for medical podcasts. You have vaulted to # 1 with your breezy style, ability to dig deeply while giving practical advice. Helps keep me sharp, especially since I sold my practice of 32 years last year. I now work for a company called NIA Magellan, We are contracted by insurance companies to review advanced imaging requests for mediical necessity. I get into a lot of interesting conversations. I have noticed a huge difference in how Docs comport themselves. Book recommendation- An Instance of the Fingerpost by Iain Pears; bets historical novel I've read. Good Luck and take care
