Answer: Cafe coronary syndrome 🍽️⭐ ★ This is acute upper airway obstruction by a food bolus, not myocardial infarction 🚨 ★ It often presents suddenly while eating with collapse, cyanosis, and inability to speak 😶 ★ The name is misleading because the event mimics a cardiac emergency 🎭 ★ Immediate airway maneuvers like abdominal thrusts can be lifesaving 🤲 ★ If obstruction persists, urgent laryngoscopy or bronchoscopy may be needed 🫁 ★ Always think choking when collapse occurs abruptly during a meal 🍴 #USMLE #EmergencyMedicine #MedEd Find more such high-yield points: oncourse.onelink.me/xW0t/install

A man suddenly collapsed while having dinner at a restaurant. People thought he was having a massive heart attack. By the time help arrived, he was unconscious. The diagnosis wasn't MI. It was a classic medical emergency with a surprisingly misleading name. Can you name it?

Answer: Resistant gram-positive infections like MRSA or VRE 🦠⭐ ★ Daptomycin is rapidly bactericidal against resistant gram-positive organisms ⚡ ★ It is used for MRSA bacteremia, right-sided endocarditis, and complicated skin infections 🫀 ★ It also covers many VRE infections when susceptibility supports it 🧫 ★ It is inactivated by lung surfactant, so it is not for pneumonia 🚫 ★ Creatine kinase should be monitored because myopathy can occur 🧪 ★ Its role is usually reserved to preserve potency and limit resistance 🛡️ #USMLE #InfectiousDisease #MedEd Find more such high-yield points: oncourse.onelink.me/xW0t/install
