Growth hormone deficiency mnemonic

Hello!

Today I'll be sharing a mnemonic on Growth hormone deficiency!

Barts hemoglobin mnemonic

So I just came across a question asking me why Barts hydrops fetalis is lethal. The answer is because Barts hemoglobin can't release oxygen to the tissues.

And I thought, "Barts can't fart oxygen." as a funny way to remember this xD

What is Barts hemoglobin anyway?

Tetramers of gamma globin chains formed when there is deletion of all four alpha globin genes.

How do you remember Barts hemoglobin has gamma chains?
I made a sentence with a lot of B's and G's. I'm not even sure if you can call it a mnemonic.
"BiG bart bargains for bar games."
I don't know if it works.

That's all!

Repeating PG entrance exam

"I'm a PG aspirant... This is my third year of PG preparation. I lost all interest in medicine. I've lost all hope too. I'm just tired of trying. I don't know who to talk to. I don't know how you get so much passion to write your blogs. I don't how to study also."

I understand that giving an exam for the third time must be really frustrating and tiring.

So my advice to you is - Make sure you prepare so well this time that it's your last attempt and that you get whichever post graduation seat you desire. Study real hard, no excuses.

It's natural that you tend to lose interest in learning repetitive facts. Maybe you should try hunting for new ideas, new perspectives and gain a different understanding of old concepts?

Google about facts you've learnt earlier. This time, instead of memorizing, think of why.

Question everything - Why does this muscle cause that movement? Why does sickle cell anemia cause leukocytosis? Why does phenytoin produce vitamin B9 deficiency?

Trust me, questions and curiosity will awaken an unexplored passion in you - The one you lost in studying the same things over and over again.

Hemoglobin and erythropoiesis mnemonics

Hi everyone! Long time no see? :D

Today, I'll be sharing a few facts and mnemonics on hemoglobin and erythropoiesis. Let's get started!

Do you know the order in which hemoglobin appear from early embryo to infancy?
It's embryonic hemoglobin first (Gower 1, Gower 2, Portland) then fetal and after that, adult.

Mnemonic: Gower goes, fetal follows, adult afterwards. 

(Also, notice the reverse alphabetical order -  G, F, e, d, c, B, A)

The alphabets also pair the chains with their respective hemoglobin!
GF - Gamma Fetal
BA - Beta Adult

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.

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.
