no such thing as munchenhausen

Saw this plastered on the pashkevilim in Yerushalayim yesterday;

Professor Ester Hertzog from the prestigious Beit Berel institute
(not known to be to pro-Chareidi, to say the least
(Beit Berel that is; I'm unaware of Professor's Hertzog's views))
claims that recent studies in England prove that
there is no such thing as munchenhausen syndrome by proxy!

Now - what does that say about our medical system?

Israeli society seems slow to learn.

If in England it has been disproved, then why do the Israeli's still hold of it?
