Diaphragmatic Palsy
Diaphragmatic Palsy: unilateral can be asymptomatic depending on patients underlying respiratory reserve; bilateral -> most mechanical ventilation dependent
Palmar erythema DDx
Palmar erythema is a non-specific finding characterised by a redness of the palmar skin.
SVC Obstruction DDx
Obstruction of the superior vena cava results from mediastinal mass lesions. Features include a plethoric and cyanosed face with periorbital oedema, exophthalmos, conjunctival injection, and venous dilatation in the fundi, distended non-pulsatile neck veins and a positive Pemberton sign.
Clubbing DDx

Shoulder pain radiating down the arm
Shoulder pain radiating down the arm can be a diagnostic dilemma, with causes arising from multiple visceral and musculoskeletal structures.
VF and VT DDx
Ventricular fibrillation and (pulseless) ventricular tachycardia mandate immediate CPR, advanced life support and correction of underlying causes.
Tachycardia DDx
Tachycardia refers to heart rate >100/min in an adult. Tachycardias are classified as regular or irregular, narrow complex or wide complex. The underlying causes of tachycardia are legion
Supraventricular tachycardia DDx
SVTs are supraventricular tachycardias, that can be either atrial tachydysrhythmias (such as atrial fibrillation) or atrioventricular tachydysrhythmias. This document concerns the latter.
Ultrasound Case 068
A 76 year old man regularly self catheterizes. His left scrotum has become gradually tender and swollen. The resident is very concerned there is a large solid mass.
Pulseless Electrical Activity DDx
Pulseless electrical activity mandates immediate CPR and correction of underlying causes.
Chest pain DDx
The approach to non-traumatic chest pain requires the early recognition and exclusion of potential life threats, then further consideration of other causes.
Cardiac Failure DDx
In emergency medicine and critical care, the cardiac failure that primarily concerns us is acute heart failure syndrome (AHFS), which refers to rapid worsening of heart failure signs and symptoms, and has many possible causes.
