Step 2 CK: Screening for Gestational Diabetes Mellitus (GDM)

Hello!

As you guys already know, GDM diagnosis can be accomplished with either of two strategies:
“One-step” 75-g OGTT or “Two-step” approach with a 50-g (nonfasting) screen followed by a 100-g OGTT for those who screen positive.

But what if, in the exam, you are asked to choose a screening test for GDM...
And the options contain both:
- One hour 50 gram glucose load test (1-h 50-g GLT)
- Two hour 75 gram oral glucose tolerance test (2-h 75-g GTT)
... Then which one do you choose?

The Burkholderian Culture : From the Authors' Diary

Hello everyone ! I'm A.P.Burkholderia , and I'm back with another post
Now a lot of people have been asking me why my name is that. Some have assumed it's my actual surname (Like our very own IkaN, but that's a whole 'nother story) while others have unraveled the mystery of the Burkholderian terminology (Like the ardent PSM-proponent Jay ). So before any more of you are boggled by this Burkholderian business I figured let's talk about why this organism is fancy enough to earn the charm of being my pen-surname. :P
So Burkholderia is a Gram negative rod. And it is one of a kind - Cause It's a Non Fermenter ! So if you were to make a TSI plate it would give you alkaline in the slant as well as the butt (LOL). Only few other organisms like Pseudomonas and Acinetobacter are non fermenters. So it's a total Aerobe and it can be checked with "High and Leifson Oxidation Fermentation media". Another cool name :D 
It's got 3 different types : 
B. cepacia 
B. mallei 
B. pseudomallei.
Now I love how it's called "Mallei". In Hindi 'Malai' means 'Milk Skin'. I find that hilarious. 
Also, 'Mai Lai' means 'I shall bring '. I find that really funny too. ( Burkholderia , Main Laiii !)
But other than that , it's a pretty serious bug. 
It causes Cepacia syndrome in Cystic Fibrosis,  which presents as a form of Bronchiectasis or Serious pneumonia. 
It can cause Meiloidosis which has a presentation similar to TB and another one called 'Glanders'. 
It shows a safety pin appearance when seen under the microscope on staining with Geimsa. 
Other than this , it's a very hard big to get rid of. 
It's almost resistant to all antibiotics and only the Carbapenems may work ! 
So this is why I love this bug. 
It's cool , it's classy and it's hard to get. :p 
Other than that , I love saying the name! *Burkholderia* 
I might do a video some day on this :p and how to say it right. 
Till then , Ciao! 
Stay awesome.

Klein waardenburg syndrome mnemonic

Here's a small post :)

Waardenburg syndrome is a rare genetic disorder most often characterized by varying degrees of deafness, minor defects in structures arising from the neural crest, and pigmentation changes.

Synonyms: Waardenburg Shah syndrome, Waardenburg-Klein syndrome.

Acute Post-hemorrhagic anemia

Hey Awesomites

Today I am gonna talk about the Anemias of blood loss, particularly the acute cases of posthemorrhagic anemia.

The Basics- Anaemia

Hey Awesomites

"Anaemia is defined as a decrease in the level of haemoglobin due to loss of a significant amount of red blood cells which decreases the oxygen- transporting capacity of blood."

Cushing's Reflex in Meningitis : Mnemonic and Explanation


Hello everyone !
Another short post on a very important triad. Cushing's!

Cushing's reflex
It occurs in response to raised Intracranial Pressure (ICP/ICT)

Mnemonic

HIB

H - Hypertension
I   - Irregular Breathing
B - Bradycardia

Mechanism :
So just imagine :
Due to some reason you develop an increase in the ICT.
We know that blood flows from High Pressure to Low Pressure. Generally , the CSF pressure is lower than the BP.
However after a point , the ICT is bound to become equal to or even more than the systemic BP!
If that happens , the blood flow to the brain is decreased and the Brain can get ischemic (cause the Cranial pressure would be higher. So the body won't be able to pump the blood into it.)

Thus, in order to compensate for this , the sympathetic system is activated. The body's peripheral vessels undergo constriction to raise the BP. This would keep them at a higher pressure than the Cranium thus keeping the blood flow intact for a while at least. This causes the Systemic Hypertension.

In a way it's the last ditch effort to save the brain!
Due to sympathetic stimulation the respiratory centers get stimulated too and it's all weird so it causes Irregular Respiration.

Now you'd expect Tachycardia when there is so many Sympathetic juices flowing through your body.
But no. Things aren't as simple as that.

The aortic baroreceptors sense the increased BP and end up decreasing the Heart Rate. Resulting in Bradycardia. So in a way that's the 2nd phase of this Reflex!

The Reflex serves as a marker of raised ICT as that is the event that puts the whole cycle into place.
This generally occurs as the body's last resort to restore blood to the brain.
What a wonderful Homeostatic mechanism !!

Hope this helped !
Stay awesome !

Reynolds pentads


Hello readers ! Today's blog is sweet and simple.

Reynolds pentads are collection of signs and symptoms appearing when there is obstructive cholangitis -infection of bile duct usually caused by bacteria .Following are the diagnostic features of the reynolds pentads with simple  mnemonic.
   RJ -FHC.
R-Right upper quadrant pain .
J-Jaundice .
F-Fever .
H-Hypotension.
C-Confusion .
By the way the first three diagnostic features are also called as Charcot's triad so we can also say Reynolds traid is combination of charcot's triad with low blood pressure and mental confusion .


Stay awesome:)

Tuberculosis : Ocular Manifestations

Hello everyone !
This is a short post about the manifestations of Tuberculosis in the eye.
TB is associated with a lot of findings in the eye.
We can classify them as :
1. Disease related.
2. Therapy related.
Let's look at the first one.
1. Disease related :
A. Extra Ocular structures -
    I. Appendages :
       Eyelid - Lupus Vulgaris. Lid granuloma.
       Lacrimal apparatus - TB Dacryoadenitis. Dacryocystitis.
      
    II. Orbit :
         Orbital Cellulitis.
         Orbital Pseudotumor.
B. Ocular manifestations -
    
     I. Conjunctiva -
         Phlyctenular Conjunctivitis - due to hypersensitivity to Tuberculin. Seen as intense itching , discharge , redness and nodules.
     II. Cornea -
          Interstitial Keratitis
     III. Uvea -
          Granulomatous uveitis ( Chronic anterior Uveitis ). Shows Mutton Fat appearance.
          Choroiditis - Choroid Tubercles - classic of TB Uveitis. Tuberculoma may be seen. Miliary choroid nodules may be seen.
      IV. Retina -
            Eale's disease - may be a result of Hypersensitivity to Tuberculin. Although causality is not established clearly.
           Sub retinal Tubercles.
2. Therapy Related :
       A. Ethambutol - may cause Optic Neuritis - generally retrobulbar type. With Color Blindness.
      B. INH - Isoniazid can cause retrobulbar optic neuritis, although this is much rarer.
     C. Immune Reconstitution Inflammatory Syndrome - When a person recuperates from TB /HIV his immune system may become hyperactive and show Immunologically mediated uveitis.
Hope this helps !
Happy studying.
Stay awesome.
