Tips on how to find vein or phlebotomy

Study: Know your anatomy, so if you can't see or feel the veins, you still know where to go.

Just the anatomy of where the veins are. Sometimes you can't see them (old people, people with dark skin) and you can't really feel them. I've done some blind insertions before successfully.

Dont panic: Initially, you will find it hard, but do not get embarrassed if you miss.

Tourniquet: Tying a torniquet often helps by making the vein more swollen and prominent.

In our hospital, the patient's relative is asked to hold with the fingers tightly around the arm instead of using torniquets.

Study group discussion: Carcinoid syndrome

What's carcinoid syndrome?

It's caused by serotonin. There's a GI tumor called carcinoid tumor which secretes it. So basically, the syndrome is caused by serotonin (Flushing, wheezing, etc)

What's the treatment for carcinoid?

Somatostatin analog, octreotide.

Which vitamin deficiency is associated with carcinoid syndrome?

Study group discussion: What causes Carharts notch?

In otosclerosis, why carharts notch at 2000 Hz in PTA?

Carhart attributed this phenomenon to "mechanical factors associated with stapedial fixation."

But why the greatest dip at 2 kHz?

The ossicular chain has two basic modes of vibration. The first mode, with a peak around 1200 Hz, is the primary mode for AC stimulation. This mode is associated with a "hinging" motion of the ossicles caused by AC stimulation of the tympanic membrane at the umbo. The second mode, with a peak around 1700 Hz, is described as a "pivoting" motion of the malleus/incus, with an axis of rotation somewhat orthogonal to the axis of rotation associated with the "hinging" motion. The second mode is less robust than the primary mode for AC stimulation, but it is the dominant mode when excited by BC stimulation. A decreased mobility of the ossicular chain at 1700 Hz due to otosclerosis also affects the surrounding frequencies, but is seen most prominently as a BC loss at 2000 Hz in audiometric testing.

Causes of carpal tunnel syndrome mnemonic

Short post for the day!

Mnemonic: CARPAL Tunnel Syndrome

Atypical carcinoid syndrome mnemonic

Happy Friday everyone!

Carcinoid tumors are neuroendocrine tumors of the GI tract. They can make high levels of neuropeptides and amines, like serotonin, which can cause brief episodes of flushing, diarrhea, cough, wheezing, shortness of breath, heart disease, and in rare cases, pellagra. (Typical carcinoid syndrome)

Atypical carcinoids have a normal plasma serotonin level. They are characterized by extended episodes of deep purple flushing, headache, shortness of breath, and in rare cases, lacrimation (tears).

Triad of pheochromocytoma mnemonic

To remember the classic triad of pheochromocytoma, remember 3 P's.

Study group discussion: Pharmacology of drugs used in Parkinsons disease

Why does bradykinesia and rigidity occur in Parkinson's disease?

Bradykinesia is due to deficiency of dopamine.
Rigidity is due to uncompensated increase in acetylcholine.

Why levodopa is always given in combination with carbidopa and entacapone? 

Carbidopa is given to protect levodopa against dopa decarboxylase enzyme which causes its peripheral breakdown. Peripheral conversion of dopamine is harmful.. Can cause cardiac arrhythmias and postural hypotension.

Entacapone is given to block COMT.

Difference between entcapone and talcapone?

Study group discussion: Why are platelets low in hepatic disease?

Why are platelets low in hepatic disease?

You need cytokines to tell the marrow to synthesis platelets. They are synthesized chiefly by liver.

It is also been associated with the concept of hypersplenism leading to sequestration of thrombocytes in the enlarged spleen.

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!)

Why is gout more common in men?

Hey everyone!

I was trying to find out is hyperuricemia in Von Gierkes disease gender specific.. I didn't get the answer to my question (If you do, please let me know!), but I did found out that hyperuricemia, in general, is more common in men.

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 –

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?

Ethosuximide mnemonic

Greetings everyone!

This little pharmacology pearl was written by Keto :)

eThosuximide is the T drug.

It blocks the T-type Ca2+ channels:
T stands for Transient which can be found in the Thalamus.

Remember, that thalamus is a relay nucleus with a lot of subnuclei. Everything travels through, EXCEPT smell. So a patient with "Transient" absence (peTiT mal) seizure, you can let them smell something to bring them back. And... eThosuximide is the drug they need.

Study group discussion: Monroe Kenri's Law

Here's a cool fact:

Monroe Kenri's law states that cerebral perfusion pressure = Mean blood pressure (MBP) - Intracranial pressure (ICP)

Hence, in cases of increased ICT or intrcranial heamorrhage, BP rises.
This is physiological so that blood supply to the brain can be maintained.

Hence, in cases of stroke, never try to reduce BP unless it is above 200. If you reduce BP, the blood supply to brain is compromised.

Cushing's triad in cases of increased ICT:
1. Increased BP
2. Bradycardia
3. Irregular respiration.
(Because increased ICP compresses the brain stem)

Bleomycin metabolism

This is a short post on pharmacology!

Bleomycin is inactivated by a cytosolic cysteine proteinase enzyme, Bleomycin hydrolase.

This enzyme is widely distributed in normal tissues with the exception of the skin and lungs, both targets of Bleomycin toxicity.

This is why, Bleomycin causes pulmonary fibrosis.

It's also why bleomycin is used in skin cancers like squamous cell cancer.

That's all!

Tarsal Bones Mnemonic

Hey guys, Jay here once again. Today I was studying my anatomy, and our lower limb region is going on. Since our regional exam is next week, I wanted to study the foot and especially the tarsal bones. Me, the one who is so fond of mneumonics, tried finding some mnemonic to remember the tarsal bones. I found one on internet I made one myself. So let me first list the tarsal bones.
1. Calcaneous
2. Talus
3. Navicular
4. Medial cuneiform
5. Intermediate cuneiform
6. Lateral cuneiform
7. Cuboid

The one on Internet:

The Circus Needs More Interesting Little Clowns

But in this Calcaneous and Talus have exchanged places. So when I saw this, I edited it a bit. :) So it kinda goes with the first syllable as well. ^_^

CaT Navy Meets Interesting Little Cubs

CaT has Calcaneous and Talus both.

Hope it helped Awesomites. :) Until we meet again then, Ciao!! Au revoir!!! :D

Heart murmurs mnemonic

Hello people with a pumping heart in their chests, obviously! <3

In this post, I'll be taking about the few mnemonics I use in relationship to murmurs.

"PASS" is a good mnemonic for remembering that pulmonic and aortic stenosis give a systolic murmur.

The opposite of PASS, ie, other two valves and the other defect gives a systolic murmur too. (Mitral and tricuspid regurgitation gives a systolic murmur!)

VSD has a S so that's systolic.

Now, the other ones - pulmonic and aortic regurgitation, mitral and tricuspid stenosis will cause diastolic murmurs :)

Here's another mnemonic submitted by one of the readers:

Primary, secondary and tertiary hyperparathyroidism mnemonic

This idea was submitted by Keto. It helps go through Calcium and Phosphorous levels very quickly.

The values are somewhat logical and can be thought through.. But if you're on ward or on a board exam this can be handy.

Making Referrals - Bio Medical Ethics

Hey awesomites, I'm Jay, and I'm your new Medicowesome contributor! yayy!! :) And today we are going to talk about Referrals. This is another important ethical responsibility of a physician.

A physician’s Central responsibility is WELFARE OF THE PATIENT, and that means, Physician should work for the best interest of the patient not him/herself.

Referral simply means that, when we reach the boundaries of our competence, we should hand our patient to a more competent physician. Keeping a patient with ourselves to hide our incompetency or to earn more money is a huge NO-NO!!!

We shouldn’t be ashamed to ask for help from our colleagues, and we shouldn’t be continuing to treat a patient, if we cannot give him/her a fruitful therapy as our boundary of competency has reached. That’s when we should write a LETTER OF REFFERAL to a Consultant(BritE)/Attending(AmE) Physician or to another colleague with a broader knowledge or idea of the subject.

Bio Medical Ethics - by Jay ™

Today’s blog post is about Bio Medical ethics or Ethics of Medical care that a health care practitioner has to adhere to.

Medical ethics started off as Hippocratic Oath made in 460~ BC in the Book called Corpuz Hippocratum.

“Do No Harm” is the Primary Ethical concern of Medical Ethics.

Study group discussion: Drunken crab syndrome

Which parasite causes the drunken crab syndrome?

Paragonimus westermani.

Drunken crabs, because man gets infected with it by eating raw crabs. In Taiwan, these crabs are marinated in wine. Hence, the name!

Also called kejang.

Wow I didn't know this.

Nice to know, I was formulating all sort of weird possibilities for symptoms based on that.

I thought of a motion abnormality.. Since crabs can walk sidewise.

When I first came across this... Even I thought that the person would have a drunken gait or something!

Wonder how a crab would walk in cerebellar ataxia.. Considering they have a cerebellum.. Or not!

Lets talk about crabs!

Crabs is also slang for STD.
It's not slang, my bad. It's lice in pubic hair. Also known as crab lice.

CRAB is used for Multiple Myloma symptoms too.
CRAB:
C = Calcium (elevated),
R = Renal failure,
A = Anemia,
B = Bone lesions

And then there's Krabbe's disease, some sort of leucodystrophy.

Lame mnemonic for drunken crab.. Our teacher said -- Mr. Krabs gets drunk in Taiwan .. Because he found out.. His daughter "P"earl  (paragonimus) is a man (westermanii)

Nice mnemonic!

Typhoid: Leukopenia, chronic carrier state and cancer (Why does typhoid fever cause leukopenia?)

I see a lot of patients with typhoid in the casualty and usually, they all have leucopenia. So I wondered - Why does the WBC count decrease in typhoid or enteric fever? Why does the WBC count become low unlike other infections?

After loads and loads of Googling, I found the answer to my question.
