This episode goes into the mechanisms of hyperparathyroidism-associated osteoporosis and bone loss.

Methimazole-induced cutaneous eruptions  represent the most frequent side effect of thionamide therapy, ranging from  minor rashes  to  life-threatening systemic syndromes . These reactions occur when the drug acts as a  hapten , binding to proteins to trigger  complex immune responses  involving T-cell activation or antibody-mediated damage. While  genetic factors  and higher dosages increase sus...

This episode goes into the details of post-menopausal osteoporosis and how estrogen deficiency leads to reduced bone strength.

This episode describes the procedure and pitfalls of AVS (everyone’s favorite test) Core AVS Indices and Interpretation Adrenal venous sampling relies on three sequential biochemical indices to determine whether primary aldosteronism is unilateral or bilateral. The first step calculates the Selectivity Index to confirm that the catheter tip was positioned correctly inside the adrenal lumen rather...

This episode compares the effectiveness of  levothyroxine (LT4) ,  combination therapy (LT4+LT3) , and  desiccated thyroid extract (DTE)  in treating adults with  primary hypothyroidism .  The 2021 crossover trial by Shakir & Hoang et al. evaluated 75 hypothyroid patients across three 22-week treatment arms: Levothyroxine (LT4) monotherapy, LT4 + Liothyronine (LT3), and Desiccated Thyroid Extract...

This podcast episode explores the complex differential diagnosis of inappropriate thyroid-stimulating hormone secretion, a clinical paradox characterized by elevated free thyroxine alongside unsuppressed thyroid-stimulating hormone.
