The Rx Bricks Podcast

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 develop at a younger age and may involve several endocrine organs over a patient’s lifetime.

In this AudioBrick, we review the three major MEN syndromes—MEN1, MEN2A, and MEN2B—including their characteristic tumors, genetic causes, clinical features, and management.

After listening to this AudioBrick, you should be able to:

Define multiple endocrine neoplasia and identify the three major MEN syndromes.

Compare the key clinical features of MEN1, MEN2A, and MEN2B.

Describe the genetic mutations associated with each syndrome.

Summarize the basic approach to management and surveillance.

In this episode, we explore stimulants and cognitive-enhancing drugs, medications used to improve alertness, attention, memory, and cognition. You’ll learn how commonly used agents such as amphetamines, methylphenidate, modafinil, caffeine, donepezil, rivastigmine, galantamine, and memantine work, along with the conditions they’re used to treat. We’ll also review important adverse effects, contraindications, and serious safety concerns, including cardiovascular complications, growth suppression, stimulant toxicity, and Stevens-Johnson syndrome. By the end, you’ll be better prepared to weigh the risks and benefits of these medications in clinical care.

After listening to this AudioBrick, you should be able to:

Name conditions for which stimulants and cognitive-enhancing drugs are used as treatment.

Describe the mechanism of action of stimulants and cognitive-enhancing drugs.

List the main examples of stimulants and cognitive-enhancing drugs.

Describe the significant adverse effects of stimulants and cognitive-enhancing drugs.

You can also check out the original brick on Stimulants and Cognitive-Enhancing Drugs from our Psychiatry collection, which is available for free.

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 potassium handling in the collecting duct. By the end, that furosemide-and-potassium puzzle will make complete sense.

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 the major risk factors, clinical course, and complications of gallstones.

Distinguish acute from chronic cholecystitis.

Describe the treatment of gallstones and acute cholecystitis.

Digestion is regulated by a complex network of hormones, peptides, and neural signals. In this episode, we review the major gastrointestinal hormones, introduce several secondary regulatory peptides, and explain how the GI tract senses its luminal contents and integrates multiple signals to control digestive function.

After listening to this episode, you should be able to:

Identify the source, release stimulus, and function of the major gastrointestinal hormones, including secretin, cholecystokinin (CCK), gastrin, and vasoactive intestinal peptide (VIP).

Summarize the release stimuli and functions of key GI regulatory peptides, including bombesin, GLP-1, GLP-2, ghrelin, leptin, motilin, somatostatin, and glucose-dependent insulinotropic polypeptide (GIP).

Explain how the physical and chemical properties of luminal contents are sensed and how they trigger hormonal responses.

Describe how GI cells integrate hormonal and neural inputs to regulate digestive function.

You can also check out the original brick on Gastrointestinal Regulatory Substances from our Gastrointestinal collection, which is available for free.
