Bilirubin Classification by Pathophysiology

Prehepatic: Predominantly unconjugated (indirect) hyperbilirubinemia, typically due to increased bilirubin production from hemolysis. LDH and reticulocyte count ↑, while haptoglobin ↓.

Hepatic: Mixed conjugated and unconjugated hyperbilirubinemia due to impaired hepatocellular uptake, conjugation, or excretion. Common causes include hepatitis, cirrhosis, and drug-induced liver injury. ALT/AST are often elevated in hepatocellular injury.

Posthepatic: Predominantly conjugated (direct) hyperbilirubinemia due to impaired bile flow (cholestasis/obstruction). Common causes include choledocholithiasis and malignant biliary obstruction. ALP and GGT are typically elevated.

The headache red flag classically associated with Giant Cell Arteritis (GCA)

🚨 Never ignore these headache red flags!
Most headaches are benign—but a few can signal a life-threatening emergency. Recognizing these warning signs early can save a patient's life.

🧠 Today's high-yield takeaway: If a patient presents with a sudden thunderclap headache, focal neurological deficits, progressive worsening, systemic symptoms, or a new headache after age 50, think beyond a primary headache disorder.

💡 Clinical Pearl: Treat the cause, not just the pain.
📌 Save this post before your next ward round, OSCE, USMLE, PLAB, MRCP, or residency exam.

Dengue fever

🦟 Dengue Fever: Know It. Spot It. Stop It.
Dengue fever is a mosquito-borne viral illness that can become life-threatening if warning signs are ignored.
Early recognition, proper hydration, and timely medical care are the keys to preventing severe complications.

Remember: the most dangerous phase often begins when the fever starts to come down—not when it's at its highest.
Stay informed, protect yourself from mosquito bites, eliminate standing water around your home, and share this infographic to help raise awareness.

Digoxin Mechanism of Action

Inhibits Na⁺/K⁺-ATPase in cardiac myocytes → ↑ intracellular Na⁺ → ↓ Na⁺/Ca²⁺ exchange → ↑ intracellular Ca²⁺ → positive inotropic effect (increased myocardial contractility).

Increases vagal tone and decreases sympathetic activity → slows SA node and AV nodal conduction and increases AV nodal refractoriness.
Clinical effects: ↑ cardiac output and ↓ ventricular rate in atrial fibrillation/flutter.
