A patient with long-standing GORD presents with progressive dysphagia to solids first, then liquids. Endoscopy shows smooth, concentric narrowing of the distal oesophagus.
➡️ What is the most likely diagnosis?
✅ Diagnosis: Peptic oesophageal stricture
✅ Cause: Chronic gastro-oesophageal reflux disease (GORD)
✅ Endoscopy: Smooth, concentric distal narrowing
✅ Symptom Pattern:
Solids → Liquids (progressive mechanical obstruction)
🧠 Mnemonic
“GORD → Scarring → STRICture”
🟦 FRONT:
Cirrhotic patient presents with hypotension, haematemesis, and melaena. Most appropriate initial management?
🟩 BACK:
✅ IV octreotide + urgent endoscopic band ligation
✅ Give IV antibiotics (ceftriaxone)
✅ Resuscitate with fluids + blood
✅ TIPS only if bleeding refractory
Mnemonic: “VARIX = OCT + SCOPE + ABX”
🔍 Key Clues from the Stem
Sudden worst-ever headache → SAH
Young (36 years)
Hypertension
Recurrent UTIs
Right-sided abdominal discomfort
Family history of early stroke
CT shows subarachnoid haemorrhage
🔎 Other Possible Clues That Could Lead to the SAME Answer
Palpable bilateral renal masses
Flank pain
Haematuria
Progressive renal failure
Berry aneurysm on angiography
Family members with kidney disease
Autosomal dominant mutation (PKD1/PKD2)
Progressive formation of renal cysts
Causes:
✅ Hypertension
✅ UTIs
✅ Flank/abdominal discomfort
Also causes berry aneurysms in Circle of Willis
Aneurysm rupture → subarachnoid haemorrhage
💊 Management (NICE / BNF Level)
✅ Acute SAH
Admit to neurosurgical ICU
Nimodipine to prevent vasospasm
BP control
Definitive aneurysm treatment:
Endovascular coiling or surgical clipping
✅ Long-Term ADPKD Management
Aggressive BP control (ACE inhibitors)
Renal function monitoring
Family screening

🔍 Key Clues from the Stem
Sudden-onset palpitations
Shortness of breath + lightheadedness
Heart rate = 160 bpm
Regular, narrow-complex tachycardia
No visible P waves
Haemodynamically stable
🔎 Other Possible Clues That Could Lead to the SAME Answer
“Sudden racing heart that stops abruptly”
Young patient with no structural heart disease
“Neck pounding” (AVNRT)
Valsalva partially slows the rhythm
History of previous similar brief episodes
🧠 Pathophysiology
AV nodal re-entry tachycardia (AVNRT)
Re-entrant electrical circuit within AV node
Causes:
Rapid regular ventricular rate
Narrow QRS (normal ventricular conduction)
Absent visible P waves
Adenosine → transient AV node block → terminates re-entry loop
💊 Management (NICE / BNF Level)
✅ Stepwise Acute SVT Management
Vagal manoeuvres
If unsuccessful:
IV Adenosine 6 mg rapid bolus
If no effect → 12 mg IV
Continuous ECG monitoring required
✅ If unstable → synchronized DC cardioversion
A. IV beta-blockers → Used for rate control in AF/flutter
C. Oral calcium channel blockers → Not used acutely in ED
D. Electrical cardioversion → Reserved for haemodynamically UNSTABLE patients
E. IV digoxin → Chronic rate control in AF, not acute SVT termination
What is the first step in managing a stable patient with regular narrow-complex tachycardia at 160 bpm and absent P waves?
Vagal manoeuvres
If unsuccessful, proceed to IV Adenosine.
What medication is used to terminate AV nodal re-entry tachycardia (AVNRT)?
IV Adenosine
Administer 6 mg rapid bolus, followed by 12 mg if no effect.
True or false: Electrical cardioversion is used for stable patients with SVT.
FALSE
Cardioversion is reserved for haemodynamically unstable patients.
What are the key ECG findings in AV nodal re-entry tachycardia (AVNRT)?
Indicates a re-entrant electrical circuit within the AV node.
What is the pathophysiology of AV nodal re-entry tachycardia (AVNRT)?
Re-entrant electrical circuit within AV node
Causes rapid regular ventricular rate and narrow QRS.
List the steps in acute SVT management.
If unstable, synchronized DC cardioversion is required.
What is a common trap in managing true SVT?
Giving beta-blockers first
This is incorrect; beta-blockers are used for rate control in AF/flutter.
What mnemonic can help remember the management of stable SVT?
Regular + Narrow + No P = ADENOSINE
This highlights the key ECG features leading to the use of adenosine.
What is the haemodynamic status of a patient with stable SVT?
Haemodynamically stable
This indicates that the patient does not require immediate cardioversion.
What should be monitored continuously during the administration of IV Adenosine?
ECG monitoring
Essential to observe the patient’s response and any potential complications.
What are the key clues for suspected Diabetes Insipidus?
Other possible clues include dry mucous membranes, low urine specific gravity, and a history of head injury or pituitary disease.
What is the pathophysiology of Diabetes Insipidus?
Urine osmolality distinguishes primary polydipsia from DI.
What is the best next investigation for a patient suspected of having Diabetes Insipidus?
Urine osmolality
This test confirms diabetes insipidus vs psychogenic polydipsia.
What is the management for Central Diabetes Insipidus if confirmed?
Desmopressin
For Nephrogenic DI, treatment includes thiazide diuretics and a low-salt diet.
True or false: Hyperglycaemia is a key feature of Diabetes Insipidus.
FALSE
Diabetes Insipidus is confused with diabetes mellitus, but it does not present with hyperglycaemia.
What are the common traps to avoid when diagnosing Diabetes Insipidus?
These traps can lead to misdiagnosis and inappropriate management.
Fill in the blank: The mnemonic for remembering the signs of Diabetes Insipidus is __________.
THIRST + TANKING Na
This mnemonic helps recall the key features associated with Diabetes Insipidus.
What are the clinical clues indicating Diabetes Insipidus?
These clues help in the initial assessment of the condition.
What is the first-line treatment for Benign Paroxysmal Positional Vertigo (BPPV)?
Epley manoeuvre
The Epley manoeuvre is used to reposition dislodged otolith crystals in the posterior semicircular canal.
