A COPD patient can be heard wheezing from across the ward with a pCO₂ of 80mmHg and actually have a stable O₂ saturation, while their neighbor with interstitial lungContinue reading “Episode 124- One of the Fastest Reactions in the Human Body”

Why do patients with active lupus have a low CRP? Although the erythrocyte sedimentation rate (ESR) is typically high in active lupus, C-reactive protein (CRP) is often normal. What’s particularly cool about this finding is that it lends insights into the mechanism of lupus and potentially its cause. The earliest report alluding to this discordanceContinue reading “Episode 122 – When CRP goes missing”
