1. High-Yield Flashcards
Tap each question to reveal its answer.
What symptom identifies oropharyngeal dysphagia?
Difficulty initiating swallowing, often with coughing or choking.
What swallowing pattern suggests a mechanical narrowing?
Solids become difficult before liquids.
What pattern suggests an esophageal motility disorder?
Difficulty swallowing solids and liquids from onset.
What investigation visualizes and biopsies an esophageal lesion?
Upper GI endoscopy with biopsy where indicated.
Which test confirms suspected achalasia after excluding obstruction?
Esophageal manometry.
What is the main danger of food bolus impaction with inability to swallow saliva?
Complete obstruction and aspiration; urgent endoscopic assessment.
What does coffee-ground vomitus suggest?
Blood altered by gastric acid within the upper GI tract.
Which physiological findings suggest major GI blood loss?
Tachycardia, poor peripheral perfusion, hypotension or reduced urine output.
Why can NSAIDs predispose to peptic ulcer bleeding?
Reduced protective gastric prostaglandins increase mucosal injury.
How are bleeding esophageal varices usually controlled endoscopically?
Variceal band ligation.
Is routine nasogastric lavage required for every upper GI bleed?
No; it has selected uses and must not delay resuscitation or endoscopy.
What vomiting pattern suggests hypertrophic pyloric stenosis?
Progressive projectile non-bilious vomiting in early infancy.
What acid–base disorder follows prolonged pyloric vomiting?
Hypochloremic metabolic alkalosis, often with hypokalemia.
What does green bilious vomiting in a neonate demand?
Urgent assessment for bowel obstruction, especially malrotation/volvulus.
What finding distinguishes physiological infant reflux from concerning vomiting?
Normal growth and wellbeing favour uncomplicated reflux.
What is the thiamine-related safety rule in prolonged severe HG?
Give thiamine before dextrose-containing fluids.
2. Mnemonics
Three short cues for recalling important clinical distinctions.
Dysphagia history clues
SOLID
S — Solids first suggests narrowing; O — Onset with both consistencies suggests motility; L — Loss of weight is alarming; I — Initiation difficulty suggests oropharyngeal disease; D — Drooling/inability to swallow saliva needs urgent assessment.
Upper GI bleed: immediate priorities
ABC
A — Airway protection when threatened; B — Breathing assessment; C — Circulation assessment and resuscitation before definitive endoscopy.
Infant vomiting: first discriminators
BAG
B — Bile colour (true green is urgent); A — Age at onset; G — Growth and hydration status.
3. Memory Tables
Brief comparisons for commonly confused presentations.
Dysphagia: key clinical distinctions
| Feature | Mechanical / structural | Motility / oropharyngeal |
|---|---|---|
| Swallowing pattern | Solids first; may progress to liquids | Motility: solids and liquids from onset |
| Typical clue | Progressive narrowing or reflux-associated stricture | Motility: retained food/regurgitation; oropharyngeal: choking |
| Useful investigation | Upper GI endoscopy ± biopsy | Manometry for motility; swallowing assessment for aspiration |
Vomiting: age and urgency
| Presentation | Recognition clue | Clinical action |
|---|---|---|
| Physiological infant reflux | Effortless regurgitation; normal growth | Feeding advice; monitor |
| Pyloric stenosis | Projectile non-bilious vomiting | Ultrasound; correct fluids/electrolytes before surgery |
| Suspected bowel obstruction | Green bilious vomiting ± distension | Nil by mouth; urgent surgical review |
| Hyperemesis gravidarum | Pregnancy; inability to retain intake | Assess hydration/electrolytes; antiemetics |
4. Rapid Revision Points — Last-Minute Revision
- Dysphagia with weight loss or rapidly progressive symptoms needs prompt structural assessment.
- Choking or wet voice during swallowing suggests aspiration risk.
- Endoscopy identifies structural disease; manometry assesses esophageal motor function.
- Upper GI bleeding severity follows hemodynamic stability, not estimated vomited blood alone.
- Early hemoglobin may not reflect the full extent of acute hemorrhage.
- Nonvariceal ulcer bleeding may require endoscopic hemostasis and PPI therapy.
- Suspected variceal bleeding in cirrhosis calls for vasoactive treatment, antibiotics and urgent endoscopy.
- Infantile pyloric stenosis: gastric acid loss produces hypochloremic alkalosis.
- Green bilious vomiting in an infant needs urgent assessment for obstruction/volvulus.
- Hyperemesis severity is based on intake, function, hydration and metabolic impact—not ketonuria alone.
5. Clinical Memory Hooks
Presentation → interpretation or clinical action.
Progressive solids-first dysphagia + weight loss → Consider an obstructing esophageal lesion and arrange prompt endoscopy.
Melena + tachycardia + cool extremities → Possible significant upper GI blood loss; prioritize resuscitation.
Hungry 6-week-old + projectile non-bilious vomiting → Suspect pyloric stenosis; investigate by ultrasound.
Early pregnancy + prolonged vomiting + confusion/ataxia → Suspect thiamine deficiency and Wernicke encephalopathy.
6. Starred High-Yield Exam Points
- Progressive dysphagia and unexplained weight loss → urgent assessment for esophageal malignancy.
- Upper GI hemorrhage with shock signs → resuscitate before definitive endoscopic treatment.
- Bleeding peptic ulcer → endoscopic hemostasis when indicated; varices → endoscopic band ligation.
- Green bilious neonatal vomiting → urgently exclude malrotation with volvulus.
- Pyloric stenosis → correct dehydration and alkalosis before pyloromyotomy.
- Prolonged severe hyperemesis → thiamine before intravenous dextrose.
