Criteria for LVH in ECG

Hey everyone!

Someone requested me to do a criteria for LVH in ECG. Here are a few!

Cornell criteria: Add the R wave in aVL and the S wave in V3. If the sum is > 28 mm in males or > 20 mm in females, then LVH is present.

Mnemonic: 20 carnivals tree
caRniVALS (Corn evil? Cornell?) tree
R in aVL (caRniVaL).
S in V three (tree).
3 looks like a Mirrored 8.
So 28 in Males, 20 in females.

ORS and baby - My ORS week poster

It's ORS week again! And this time, I made the poster in Marathi, one of my favorite languages!

For all those who don't know Marathi, here's a translation. (The dialogue might not sound as cute in English, but here it goes!)

Difference between secondary and superinfection

Should antibiotics be prescribed for an adult with the usual fever, headache and sore throat symptoms?

Not unless he develops secondary bacterial infection.

Metachromatic Leukodystrophy mnemonic

Inspired by the case I saw in the OPD yesterday, I thought I'd share a mnemonic I use to remember the same.

"Aryl has many Colorful look a like, Cerebral brothers. They are Clumsy and Crazy."

Internship diaries: Metachromatic leukodystrophy

Hey everyone! I'm posting the study group discussion we had because it's so much less to type :D

I saw a case of metachromatic leukodystrophy in the OPD yesterday.

Can anyone tell me what is metachromatic dystrophy?

For those who don't know, it's a lysosomal storage disease. Deficiency of the enzyme aryl sulfatase A causes accumulation of cerbroside sulfate.

Study group discussion: Hot vs Cold fomentation

Can anyone tell me when should we give hot fomentation and when should we give cold fomentation?

Immediately after an injury -  Cold fomentation.
Later on - Hot fomentation.

Cold is for acute injuries like sprains, joint injuries, sports injuries.

Hot is more for chronic conditions like back aches, muscle spasms.

The point is after an acute injury, you need to reduce the swelling and inflammation. So you cool the area to decrease blood flow.

After a day of injury, you would want to increase blood flow to heal the area.

Amazing!

Study group discussion: Fluids in inferior wall myocardial infarction

Why are fluids indicated in inferior wall MI?

Inferior wall MI is associated with severe hypotension. So first, correct the hypotension, then, thrombolyse.

Yes, but any reason for the hypotension?

Because inferior wall has vagal plexus. Patients with inferior wall MI are parasympathetic i.e. high vagal tone.

Study group discussion: Referred pain

Can someone please give me regions of referred pain areas?
Eg. Pain in the shoulder could infer problem with diaphragm.

Right shoulder pain - problem with gall bladder (eg. Cholecystitis)
Left shoulder and ulnar border of left arm and hand - myocardial infarction.

Knee pain can refer to hip.

Renal colic pain is referred to the back.

Splenic rupture can refer pain to left shoulder - Kehr's sign

What is Kehr's sign please?

Splenic rupture or hemorrhage irritates the diaphragm on left side and that refer s the pain to the left shoulder. Same like cholecystitis on right side.

Study group discussion: ECCE

Why ECCE is not done when zonules are not intact?

What is ECCE?

Extra capsular cataract extraction.
Because the IOL will be implanted in the remaining posterior capsule - And if the zonule is not intact, it may cause lens subluxation.

Awesome.

Study group discussion: Cystogastrotomy for pseudopancreatic cyst

One interesting question:
In cystogastrotomy, as surgical treatment for pseudo pancreatic cyst...Why do food particles don't enter from stomach to pseudocyst through the communication?
This question asked by surgical professor in OT today.

Because cyst will be always in positive pressure and clinical studies show that the cyst rapidly decompresses. Approximating the mucosa with cyst wall, which has no epithelial lining, leads to rapid shrinkage of stoma. Within few days, neither the stoma nor the cyst is evident on radiology or endoscopy.

Wow. This is great stuff!
