ACE inhibitors that are not prodrugs mnemonic and dysgeusia

Before I tell you about the mnemonic, lemme tell you about Titanic.

The captain of Titanic was not a pro in sailing because he sank the ship xD

Or because he listened to Bruce, "The press knows the size of Titanic, now I want them to marvel at her speed, too. We must give them something new to print. This maiden voyage of Titanic must make headlines!" 

Haste is waste, Bruce. Lol.

So now you know what I am talking about, here's the mnemonic:

"Captain who Listens and acts hastily is not a pro."

Scaphoid fracture mnemonic

This was sent to me by a friend, Akshay Dhaiya! I modified it a little bit :D

He likes to call the scaphoid fracture as the Spiderman fracture. Why?

Because it's caused by supination and dorsiflexion of wrist.
(Just like how spidey throws his web!)

Spiderman - Supinating and dorsiflexing the wrist xD

Why?

Pterygium is more common on the nasal side: Why?

Why do pterygia occur more commonly in nasal side?

Environmental factors, such as a warm climate, dust and UV light, are the main causes of pterygia.

Major And Minor Blood Cross Matching Compatibility Tests

Hello awesomites! Jay ™ here today, once again with a new blog post. Yayy! ^_^

Today we will discuss about Major and minor blood cross match compatibility test. This is usually performed before the transfusion of blood from a donor to a recipient in a hospital setting.

Before we get to this we need to get known to a table which we will use in the following tests.

Blood Type	Agglutinogen (Antigen)	Agglutinin (Antibody)
A	A	Anti b
B	B	Anti a
AB	A + B	None
O	None	Anti A + Anti B

In major compatibility test we mix Donor Cells (Dc) with Recipient Serum(Rs).

In minor compatibility test, we mix Recipient Cells (Rc) with Donor Serum (Ds)

For the Cells we check the Column of Agglutinogen and for Serum we check the Column of Agglutinin for obvious reasons of the place of presence of each.

So for an Example –

This post was requested by someone.. So I made a mnemonic.

Wow. 6 groups. I don't know what to say so I'm going to tell you what others said:

"The group has been good. I've learnt a lot through here. Especially spot diagnoses."

"I mean people asking questions, even though repeat, sometimes helps just to consolidate."

"Hey.. Just wanted you to know that my grades have gone up since the group :)"

These were so nice to read!

Volume of ascitic fluid, abdominal assessment in ascites and my viva incident

Hey everyone!

A colleague asked this question on the study group  - What volume of ascitic fluid are the following tests positive: Puddle sign, Shifting dullness, Fluid thrill?

What I found out - Minimum amount of fluid required for detection of ascites by various methods are:

Diagnostic tap 10 - 20 ml

Ultrasonography 100 ml

CT scan 100 ml

Puddle sign  120 ml

Shifting dullness 500 ml
Fluid thrill 1000 - 1500 ml

I would also like to add an incident that happened in my viva:

I had a patient with liver cirrhosis in my exam. The examiner asked me that which physical examination signs I knew for the detection of suspected ascites and what my findings were.

Why does thiazide, a diuretic, cause a paradoxical anti-diuretic effect in Diabetes insipidus?

Hey everyone!

I have explained this before (In one of my earlier posts on free water clearance) but someone found my language too complicated to understand. So I decided to write this post.. An explanation which is "free" of complicated terms like free water clearance. Yaay! :D

ADH absorbs water. In nephrogenic diabetes insipidus, the kidney is unresponsive to ADH.

What do you then?

You use a drug called thiazide.

Thiazide diuretics inhibit the NaCl co-transporter  in the renal distal convoluted tubule (DCT).
The DCT is water impermeable.. So the DCT action is NOT how thiazides preserve water.

Then what is preserving water?
