Model answer
Written by UPSC Answer Check against this question's marking rubric, to the expected length. UPSC does not publish answers for Mains — this is one way to score well, not an official key.
Hanging. Death due to hanging is death from suspension by a ligature around the neck, causing asphyxia, cerebral hypoxia, vagal inhibition, or cervical fracture-dislocation. Probable causes are airway compression, carotid/jugular compression, vagal inhibition, and fracture-dislocation of C2–C3. In judicial hanging, findings include a ligature mark, hangman’s fracture at C2–C3, internal decapitation, petechiae and lividity.
Hepatitis B case. The most likely diagnosis is chronic hepatitis B with cirrhosis and portal hypertension causing bleeding oesophageal varices. Microscopically, cirrhosis shows bridging fibrosis, regenerative nodules and ground-glass hepatocytes due to HBsAg in the endoplasmic reticulum. Pathogenesis: persistent HBV infection produces chronic hepatocellular injury and fibrosis; architectural distortion raises portal pressure, forming portosystemic collaterals; oesophageal varices rupture and cause haematemesis.
Acute lymphoblastic leukaemia. Clinically it presents with bone pain, pallor, fever, bleeding, hepatosplenomegaly, lymphadenopathy and CNS involvement such as headache or cranial nerve palsy. Microscopically, marrow is hypercellular with >20% lymphoblasts. FAB L1 shows small uniform blasts, L2 large pleomorphic blasts, and L3 large blasts with basophilic, vacuolated cytoplasm. TdT is positive in most precursor B/T ALL, but L3/Burkitt-like cases may be TdT negative; Auer rods are absent.
Diuretics in hypertension. Thiazide and thiazide-like diuretics lower blood pressure by reducing plasma volume and peripheral resistance; they are useful first-line or add-on agents, especially in elderly, salt-sensitive patients and those with heart failure. Monitoring of sodium, potassium, glucose and uric acid is essential.
Paracetamol toxicity. Excess paracetamol saturates glucuronidation and sulfation; CYP2E1 forms NAPQI, depleting glutathione. NAPQI binds mitochondrial proteins, causing centrilobular hepatic necrosis. Management includes early N-acetylcysteine, ideally within the 8-hour window, with a 150 mg/kg loading dose followed by maintenance infusion, plus supportive care. Transplant assessment is guided by King’s College criteria: pH <7.3 despite resuscitation, or all three of INR >6.5, creatinine >3.4 mg/dL and grade III/IV encephalopathy.
SGLT-2 inhibitors. They block proximal tubular glucose reabsorption, causing glucosuria, lowering glucose, intraglomerular pressure, weight and blood pressure. Advantages include cardiovascular protection, as shown in EMPA-REG OUTCOME, renal protection, weight loss and heart-failure benefit. Disadvantages include euglycaemic DKA, genital mycotic infections and volume depletion. Therefore, SGLT-2 inhibitors are best used selectively in diabetes with CVD, CKD or heart failure, after counselling on infection, hydration and DKA risk.
What "Discuss" is asking you to do
Lay the issue out from more than one side — how it arose, what is claimed for it, what is held against it, and where it now stands. UPSC attaches discuss to broad topics with several live dimensions, so coverage of the dimensions earns more than the strength of your opinion.
Structure that answers it
Set the issue up → the case as it is made → the case against → the dimension both sides leave out → where the balance now lies
Where marks are lost
Listing facts with no thread between them, or arguing one side throughout and calling it a discussion.
How this answer will be evaluated
Approach
Framework: Clinical Sequence (Definition > Aetiology/Pathophysiology > Features > Investigation/Management). (a) describe: definition > process in order > significance | (b) describe: definition > structure or process in order > significance | (c) discuss: intro > 3-4 dimensions > balanced close Full marks: Precise definitions, correct pathophysiology, and balanced management.
Key points expected
- Hanging: Asphyxia vs Vagal inhibition
- Cirrhosis: Pseudolobules and portal hypertension
- ALL: Clinical features and microscopic blasts
- Diuretics: First-line for hypertension
- Paracetamol: NAC antidote
- SGLT-2: Cardio-renal benefits vs side effects
