1) Open Angle Glaucoma.
This is the most common form of glaucoma in Western populations and is caused by the trabecular meshwork becoming silted up.

2) Chronic Closed Angle Glaucoma.
This is caused by blocked drainage through a narrow angle between the iris and the cornea with resultant scarring of the trabecular meshwork. It is more common in Asian and Chinese populations.

APUD cells = Kulchitsky cells = enterochromaffin cells = enteroendocrine cells
Should be true.

Chla-MYdia lacks MYramic acid

and chlamidia trachomatis development cycle

I came up with a new mnemonic yesterday

Obstructive-COPD or COPDstructive <80% FEV1/FVC
Restricive---ARDS or A-ReDStrictive >80% FEV1/FVC

O is before R in the alphabet, and Obstructive is <80%
Restrictive is > 80%

Check this COPD video:


This is the first post. When I have time I will try to keep the blog up to date. Everybody is very welcome to help.
