High-yield memory reinforcement and last-minute clinical revision
1. High-Yield Flashcards
Tap each question to reveal the answer.
Flashcard 1. Which enzyme pattern indicates hepatocellular injury?
ALT/AST rise disproportionately to ALP.
Flashcard 2. Which results reflect impaired hepatic synthesis?
Low albumin and prolonged PT/INR.
Flashcard 3. What structural change defines cirrhosis?
Diffuse fibrosis with regenerative nodules.
Flashcard 4. Why does cirrhosis cause portal hypertension?
Fibrosis and nodules increase intrahepatic vascular resistance.
Flashcard 5. What commonly causes ascites in cirrhosis?
Portal hypertension plus renal sodium and water retention.
Flashcard 6. What SAAG suggests portal hypertensive ascites?
SAAG ≥1.1 g/dL.
Flashcard 7. Which ascitic neutrophil count indicates SBP?
PMN ≥250 cells/mm³.
Flashcard 8. What combination suggests acute liver failure?
Acute liver injury, INR ≥1.5 and encephalopathy without cirrhosis.
Flashcard 9. What are key acute liver failure dangers?
Cerebral edema, hypoglycemia and multiorgan failure.
Flashcard 10. What is asterixis?
Brief, irregular lapses of sustained posture.
Flashcard 11. What common events precipitate hepatic encephalopathy?
Infection, GI bleeding, constipation, dehydration or sedatives.
Flashcard 12. How does lactulose help hepatic encephalopathy?
Reduces intestinal ammonia absorption and increases elimination.
Flashcard 13. Which drug reduces recurrent encephalopathy with lactulose?
Rifaximin.
Flashcard 14. What does a nodular liver with splenomegaly suggest?
Cirrhosis with portal hypertension.
Flashcard 15. Why continue HCC surveillance after hepatitis C cure?
Established cirrhosis retains residual HCC risk.
Flashcard 16. What is a major consequence of portal hypertension?
Esophageal varices and potentially severe upper GI bleeding.
2. Mnemonics
Mnemonic Title: Liver test interpretation
Mnemonic Word: I–S–E
Meaning: Injury: ALT/AST; Synthesis: albumin and PT/INR; Excretion: bilirubin.
Mnemonic Title: Hepatic encephalopathy triggers
Mnemonic Word: BICS
Meaning: Bleeding, Infection, Constipation, Sedatives.
Mnemonic Title: Ascites assessment
Mnemonic Word: S–P–N
Meaning: SAAG for portal pressure; Protein for fluid characterization; Neutrophils for SBP.
3. Memory Tables
Hepatocellular versus Cholestatic Pattern
| Feature | Hepatocellular | Cholestatic |
|---|---|---|
| Dominant enzymes | ALT/AST | ALP/GGT |
| Main process | Hepatocyte injury | Impaired bile flow |
| Next focus | Hepatitis, toxins, metabolic causes | Biliary imaging and obstruction assessment |
Acute Liver Failure versus Decompensated Cirrhosis
| Feature | Acute liver failure | Decompensated cirrhosis |
|---|---|---|
| Background | No pre-existing cirrhosis | Established chronic liver disease |
| Key presentation | Acute coagulopathy + encephalopathy | Ascites, bleeding or encephalopathy |
| Priority | Urgent liver-unit assessment | Treat complications; assess transplant suitability |
4. Rapid Revision Points — Last-Minute Revision
Must Remember:
- ALT/AST elevation indicates injury, not necessarily the degree of liver failure.
- Low albumin and prolonged INR suggest impaired synthesis; interpret in clinical context.
- Cirrhosis produces portal hypertension through increased intrahepatic resistance.
- New or worsening ascites warrants diagnostic paracentesis.
- A high SAAG (≥1.1 g/dL) supports portal hypertension.
- Ascitic PMN ≥250/mm³ requires prompt evaluation and treatment for SBP.
- Acute liver failure with encephalopathy requires urgent specialist assessment.
- Asterixis supports but does not alone establish hepatic encephalopathy.
- Treat encephalopathy precipitants alongside lactulose therapy.
- Cirrhosis requires continued HCC surveillance even after viral cure.
5. Clinical Memory Hooks
Cirrhosis + abdominal distension + shifting dullness → Ascites → diagnostic paracentesis
Ascites + fever + PMN 380/mm³ → Spontaneous bacterial peritonitis → prompt antibiotics
Cirrhosis + confusion after constipation → Precipitated hepatic encephalopathy → lactulose and trigger correction
Acute hepatitis + INR 2.4 + disorientation → Acute liver failure → urgent liver-unit assessment
6. Starred High-Yield Exam Points
- ⭐ SAAG ≥1.1 g/dL supports portal hypertensive ascites.
- ⭐ Ascitic PMN ≥250 cells/mm³ is the SBP diagnostic threshold.
- ⭐ Acute liver failure: acute injury + INR ≥1.5 + encephalopathy without prior cirrhosis.
- ⭐ Lactulose is first-line therapy for overt hepatic encephalopathy.
- ⭐ Rifaximin reduces recurrence when added to lactulose.
- ⭐ Large-volume paracentesis over 5 L generally requires IV albumin.
- ⭐ Variceal hemorrhage requires urgent vasoactive, antibiotic and endoscopic treatment.
