Mnemonic for head posture in A-V pattern squints

Chin up in what? Chin down in what? The vexing never ends. Well, as it turns out, the word 'vex' itself is here to save the day. 

Chin up- V exotropia (VEx). Remember that squint is very 'vexing'. So you stare in the sky to remember at least a fraction of what you stuffed in your brain the day before. 

Other will be A esotropia. By exclusion, it's easy to remember. 

Chin down- V esotropia or A exotropia. Again, by exclusion, these get placed naturally under this heading.

So, just remember 'VEX' and you won't be vexed anymore!

Parasitic infections and Asthma

In parasitic infection, polyclonal IgE produced by body occupies the receptor produced by mast cells. This leads to decrease action of specific IgE required for asthma. 
This mechanism is probably the cause of decrease prevalence of asthma in tropical population.

Choristomas Vs Hamartomas

I get super confused with both the following terms, so I made a lame technique to remember both of them. 

Choristomas:

It sounds more like a Christmas. So Christmas tree is usually not grown in India but we do keep it as a sign of Christmas. 
So Christmas tree is normal, but the site (India or any other habitat) is not the usual site of tree, so let's say abnormal. 
So Choristomas is normal tissue at abnormal anatomical sites.

Example - Normal pancreatic cells under the small bowel mucosa.
They are not considered as neoplasm.

Hamartomas:w

'Hamara' in Hindi means 'mine'. 
Remember: this place is mine. So here, place is normal and tissue is abnormal!
That is, abnormal tissue at normal anatomical sites.

Example - Lung hamartomas exhibit cartilage, bronchi, and blood vessels. 
They are considered as neoplasm.

That's it!

Ocular Alzheimer's disease

A paper published in 2003 has dubbed glaucoma as 'ocular Alzheimer's disease' because some of the pathophysiological elements are similar.

1. Neuronal apoptosis involves caspase activation in both the diseases.

2. Caspase activation causes up regulation of amyloid beta production due to the cleavage of amyloid precursor protein. 

3. Age related mitochondrial dysfunction plays a role in both the diseases.

4. Glutamate elevation, and nitric oxide synthase up regulation has been implicated in the neurotoxicity of the both. 

5. In the synaptic dysfunction, glutamate toxicity is involved, common to glaucoma and Alzheimer's.

Spherocytosis

Hello Awesomites !

The future blogs will be on confusers.

Q. On peripheral blood smears there is presence of spherocytes. What are the differentials and the test to identify the same?

Most of you have prompted it as hereditary spherocytosis.
 Let see.

Ans. DIFFERENTIALS :- 
  • HEREDITARY SPHEROCYTOSIS
  • AUTO-IMMUNE HEMOLYTIC ANEMIA
 Best next step is to do DIRECT COOMBS TEST to rule out autoimmune hemolytic anemia.
For hereditary spherocytosis go for osmotic fragility test.  


 So spherocytosis doesn't means Hereditary, it could be acquired, usually preceded by an infection.

HAPPY STUDYING :)
