Fact of the day: 'Experience- taking' from books

Today's fact is relatable for all medicos and books lovers <3

Yes, you can subconsciously take on the attributes of your favourite fictional characters when reading a story- not just the thoughts and beliefs of the character, but the whole state of being itself.

Well, it is more often seen in those who are depressed or who don't have much life experiences of their own.

Also, if the reader is able to relate experiences in the life of character of the story, he might take it to his own life and adopt the mindset and perspective of the character. This may lead to temporary or permanent changes in his real life.

Excessive openness to experiences may lead to schizotypal, narcissistic or paranoid personality disorders among others.


Happy reading :D

Fact of the day: Handedness arises from genes in the spinal cord

Handedness is an asymmetry arising due to left-right differences in the development of nervous system. Evidences suggest that a human embryo of eight weeks is able to move its right arm more than the left arm.

Well, if you know something about neurologic development in-utero, you must know that at eight weeks signals are not transmitted from the brain yet. Instead the signals travel from the spinal cord.

The left side of the cord matures faster than the right cord. This means the genes that control growth and development are activated faster on the left cord than the right one. In the hindbrain, it is the other way around.

Immunohistochemistry and cytogenetics for Non Hodgkins Lymphoma

Hello!

The Romberg's test does not test cerebellar function

The Romberg's test does not test cerebellar function.

This is a topic that most medical students discuss at some point of time. I have found myself in the midst of similar conversations over my years at medical school.

After much study, I happened to reach an understanding that clarified the purpose of the test and provided a way to understand the results as well.

It would help if you think of the cerebellum as a processor (such as a C.P.U. in a computer).
There are 3 main inputs:


Romberg's test (3 steps):
1. Ask patient to stand with feet together.
2. Ask patient to close both eyes.
3. Maintain the posture for 60 seconds.

The Romberg's test is positive if the patient cannot stand for 60 seconds with feet together and eyes closed.

It is essential to understand that without the processor, the inputs do not matter (as there will be no output and no result).
Thus in Cerebellar ataxia, the patient will be unable to perform any of the above 3 steps and thus the Romberg's test cannot be performed on this patient.

In a situation where the cerebellar function is intact and Romberg's test is performed:
The first input (Vision) is lost when the eyes are closed.
It is now unto the 2 other pathways (Proprioceptive and Vestibular pathways) to provide input to the cerebellum.

Thus the Romberg's test will be positive in cases of:
1. Proprioceptive dysfunction e.g. Sensory peripheral neuropathy & Dorsal column dysfunction
2. Vestibular dysfunction e.g. Vestibular neuritis

This was my attempt to provide a brief summary about this topic and it has been compiled to the best of my understanding. Please feel free to discuss it further, in the comments section below.

Have a great day!

Immunohistochemistry and cytogenetics for leukemias: Part 1

Hello!

Fact of the day: Most efficient sleep position to clear the brain of waste

Your sleep position at night matters a lot. Not head-up, nor head-down, but sleeping on your side is the most efficient position to clear waste materials from the brain.

This is because the glymphatic system (exchange of CSF with the interstitial fluid to get rid of damaging brain proteins) of our brain works most efficiently in lateral position compared to supine or prone position.

Lateral position and right posture while sleeping is considered advantageous for those suffering from neurologic and psychiatric disorders due to this reason.

Spermatic Cord contents : Mnemonic

Hello. This is about the things that your thing contains if you're a guy :p

So the spermatic cord is an important content of the inguinal canal in men.

And it contains a host of things.

Remember :

Plenty of Dick Contributes To Good Sex Life

Plenty of = Pampiniform plexus
Dick = Ductus Deferens
Contributes = Cremasteric artery
To = Testicular Artery
Good = Genitofemoral Nerve (Genital br)
Sex = Sympathetic plexus
Life = Lymphatics.

So it's 3 Arteries + 2 nerves + 3 other things.

Hope you like this !
Stay awesome.

Fascia of the thigh : Mnemonic

Hi everyone. This is a short post where I tell you about the thigh fascia.
