Immunohistochemistry and cytogenetics for leukemias: Part 2
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!

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.
So fascia of the thigh is super important during surgery , and we are expected to know its layers.
So it's got 2 layers : Camper's and Scarpa's.
Now which is outer and which is inner ?
Remember :
OC IS good.
So OC = Outer Camper
IS = Inner Scarpa
Hope you liked this!
Stay awesome.
