After American gastroenterologist Burrill Bernard Crohn,
although it was apparently first described by Giovanni Battista
Morgagni in the 16th century.
As for Bechterew's disease, my goodness...where did your friend get
that diagnosis from? I bet many doctors in Singapore wouldn't know
what that is...I had to search for it myself. It's ankylosing
spondylitis...quite common disease with the genetic association HLA
B27. It was described by various people including W. von Bechterew
(1883), Adolph Strumpell (1897), and Pierre Marie (189
. Actually ankylosing
spondylitis is more commonly known as Marie-Strumpell Disease in
Singapore, or at least that's what they taught us in NUS a long
time ago.
