Bartters, Gitelmans and Liddles syndrome mnemonic
Bartters, Gitelmans and Liddles syndrome present with chloride resistant (high urinary chloride) hypokalemic metabolic alkalosis.
What differentiates them:
Bartters: Hypercalciuric (Furosemide like! Loops lose calcium, remember?)
Gitelman: Hypocalciuric (Thiazides don't!) and Hypomagnesemia. Presents with cramping and spasms.
Liddles: Presents with hypertension, metabolic alkalosis and hypokalemia (Aldosterone excess like, but it is truly pseudohyperaldosteronism!)
Here's a mnemonic for it!
"FaceBook GoT ALL pseudo HYPER about a Little syndrome"
FB - Bartter's is like Furosemide
GoT - Gitelman Thiazide
All pseudo hyper little - Liddles is like pseudo HyperALdosteronemia (Remember, it is pseudo - aldosterone levels are normal/low)
That's all!
Here's an aphorism by Sir William Osler: “Care more for the individual patient than for the special features of his disease.” :)

Heyde's syndrome mnemonic
The mnemonic is: Heydes' hidden bleeding heart.
Pathophysiology of achalasia mnemonic
This post is about the pathophysiology of achalasia!
In achalasia, there is loss of NO and VIP releasing inhibitory neurons. Thus, the loss of the inhibitory innervation in achalasia results in the manometric consequence of failure of LES relaxation as well as loss of esophageal peristalsis.
Classification of enzymes mnemonic
This mnemonic on classification of enzymes was submitted by Mohd. Ayub Ali.
The mnemonic is, "On The Himalayas, Lyf (life) Is Lightened."

Why does Digoxin toxicity result in increased automaticity?
Atrial fibrillation in WPW syndrome
Random fact that I learnt today!
If a patient with WPW syndrome develops symptomatic atrial fibrillation, what is the drug of choice?
Answer is procainamide.
Stable patients suspected of having WPW with atrial fibrillation should not receive agents that predominantly block atrioventricular conduction, but they may be treated with procainamide or ibutilide.
Why?
Because if you block the AV node using beta blockers, calcium channel blockers or digoxin, you will favour conduction to the accessory pathway. This will worsen the arrhythmia.
That's why, in stable patients, chemical cardioversion is preferred.
If instability is present, electrical cardioversion is required.
That's all!

Organisms covered by Ampicillin mnemonic
So here it is...
Ampicillin HELPS to clear Enterococci!
Haemophilus influenzae
E. Coli
Listeria monocytogenes
Proteus
Salmonella
Ps: Gram-negative organisms have 'porin' channels in their outer lipid membrane through which the Beta-lactam antibiotics enter the cell. Also the lipopolysaccharide layer that contains endotoxins! (Gram-positive organisms do not have such things in their cell wall)
The only exception is Listeria monocytogenes that has little amounts of such endotoxins, inspite of being Gram-positive bacteria!
That's all!
