Essentials – Megaloblastic Anemia (opens the original)
Read excerpt
Megaloblast. Now there’s a word you don’t hear every day. The root -blast comes from the Greek blastos, meaning “germ” or “bud,” and is familiar from terms like blast cells—very young hematopoietic precursor cells. Megalo- comes from the Greek megas, meaning “large” or “great,” as in splenomegaly. So is a megaloblast simply a large, immature cell? Not quite. In this episode, we break down megaloblastic anemia: why it develops, what vitamin B12 and folate have to do with it, what you’ll see on a
Essentials – Multiple Endocrine Neoplasia Syndromes (opens the original)
Read excerpt
Multiple endocrine neoplasia (MEN) refers to a group of rare inherited syndromes that increase the risk of developing tumors in multiple endocrine organs. MEN affects men and women at roughly equal rates and occurs across geographic, racial, and ethnic groups. These syndromes are caused by genetic mutations inherited in an autosomal dominant pattern, meaning an affected parent has a 50% chance of passing the mutation to each child. Unlike many sporadic cancers, tumors associated with MEN often d
Essentials – Stimulants and Cognitive-Enhancing Drugs (opens the original)

We’ll also review important adverse effects, contraindications, and serious safety concerns, including cardiovascular complications, growth suppression,
Essentials – Physiology of the Renal Tubular System (opens the original)
Read excerpt
Why does a patient on furosemide end up needing a potassium supplement? In this episode we walk the length of the nephron— proximal tubule, loop of Henle, distal convoluted tubule, and collecting duct—and trace exactly how each segment reabsorbs and secretes to keep sodium, water, potassium, and acid-base in balance. Along the way we hit the transporters and drug targets that show up again and again on Step 1, from the Na-K-2Cl cotransporter that loop diuretics block to the aldosterone-driven po
Essentials – Cholelithiasis and Cholecystitis (opens the original)
Read excerpt
Gallstones are hardened deposits that form when substances such as cholesterol or unconjugated bilirubin become overly concentrated in bile. They vary greatly in size and often cause no symptoms, but stones that leave the gallbladder can obstruct the biliary tract and cause inflammation or infection. After listening to this AudioBrick, you should be able to: Compare cholelithiasis, choledocholithiasis, cholecystitis, and cholangitis. Describe how cholesterol and pigment gallstones form. Identify
