Fact of the day: Tugging on heart strings

Hey Awesomites

Since its Valentine's day, here is a love fact you need to know:

Emotional instability and stress associated with constant anxiety (in case you are suffering from I-love-you-penia or broken-heart syndrome) may actually lead to acute emotional trauma to the heart and result in rupture of heart strings, the "chordae tendineae".

The chronic negative effects on heart are associated with Takotsubo cardiomyopathy, aka broken heart syndrome which involves weakening of myocardial muscles and rupture of chordae tendineae leading to right sided heart failure, ventricular arrhythmias and rupture.

So ease your suffering by talking to the love of your life on this special day and confess about your feelings today. <3

Soap bubble appearance on X ray:Differential diagnosis

Hello everyone!
I always find X rays quite confusing especially when they appear same.
It's a short post about differentiating bone tumors.

Soap bubble appearance on X ray is expansile, eccentric vaguely trabeculated space having thin sharp defined sclerotic margins.
Mostly seen in bone tumors and other bone lesions.
On X ray they all appear same, only way to differentiate them is to know their location and other associated factors.
Commonly seen in
1) Aneurysmal bone cysts-
  Location of ABC is Metaphysis.
It occurs in younger age group i.e less
than 20 years. So the X ray of such
patient will have non fused and 
immature bone.
Preferred sites are long bones of upper and lower limb, especially femur.

2) Giant cell tumor(osteoclastoma) -
Location of GCT is epiphysis
Here the prevalent age group is 20-40, which means an adult sketetal structure.
While the preferred sites are same like ABC.
So if one see epiphyseal lesion with soap bubble appearance in mature bone, it has to be Giant cell tumor.
GCT presents with other classical signs of Egg shell crackling on palpitations.
Giant cells on histology.
Which are NOT the tumor cells. So its one of the example of misnomers. They are meant to misguide you.

Thats it :)
Stay awesome

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.


That's all
