Why ECCE is not done when zonules are not intact?
What is ECCE?
Extra capsular cataract extraction.
Because the IOL will be implanted in the remaining posterior capsule - And if the zonule is not intact, it may cause lens subluxation.
Awesome.

One interesting question:
In cystogastrotomy, as surgical treatment for pseudo pancreatic cyst...Why do food particles don't enter from stomach to pseudocyst through the communication?
This question asked by surgical professor in OT today.
Because cyst will be always in positive pressure and clinical studies show that the cyst rapidly decompresses. Approximating the mucosa with cyst wall, which has no epithelial lining, leads to rapid shrinkage of stoma. Within few days, neither the stoma nor the cyst is evident on radiology or endoscopy.
Wow. This is great stuff!
Hi. I keep forgetting that Conn's syndrome is hyperaldosteronism. Can you help me out with this?
Sure! :D
The N's are for sodium - Hypernatremia!
The C makes a K for potassium, which is less than the number of N's, therefore, hypokalemia!
Also, Na+ is sodium. A could remind you of Aldosterone.
AL could remind you of ALkalosis.
That's all!

So last night, in the emergency department, comes a 65 yr old male complaining of difficulty in passing urine.
On examination: His lower abdomen is distended. A pyriform shaped swelling reaching the umbilicus.
He was having acute retention of urine. Tried introducing a 16 fr catheter. But failed. Next step?
You try intorducing a 10 fr paediatric catheter.
But we didn't have one to our dispense. So we did supra pubic.
What is the procedure?
Palpate and percuss first. Then insert the catheter directly at 90 degree.
The moment I did.. The patient heaved a sigh of relief. On further work up, it was a case of BPH.
