OPHTHALMOLOGY--D/D DIGEST
HEY GUYS,

LETS GATHER ALL THE icon_lol.gif icon_lol.gif D/D'S icon_lol.gif icon_lol.gif OF VARIOUS DISEASES( OR SOMETIMES THE icon_lol.gif icon_lol.gif CAUSES icon_lol.gif icon_lol.gif OF VARIOUS SYMPTOMS like dysphagia, nose block) IN THIS PLACE. I FIND THAT THIS IS A VERY HIGH YIELDING TOPIC AND IS NOT GIVEN COMPLETELY N WELL IN ANY SINGLE BOOK. SO ALL OF THEM IN A SINGLE PLACE WILL BE A GREAT AID TO REVISION OF THIS EXTREMELY VOLATILE TOPIC. I HUMBLY REQUEST ALL MEMBERS TO MAKE A SINCERE EFFORT TO CONTRIBUTE HERE


PLZ CONTRIBUTE AS THE ONE WHO WILL BENEFIT THE MOST IS U FOR IT IS AS EASY FOR ONE( LIKE ME) TO READ THINGS FROM HERE OR BOOKS N FORGET AS FOR U TO WRITE THEM DOWN HERE AND REMEMBER FOR A LONG TIME.

SHARING KNOWLEDGE WILL INCREASE IT MANY FOLDS--- THE WISE
SHARING KNOWLEDGE WILL MAKE OTHERS BETTER THAN ME--- THE FOOL.


SO TYPE IN D/D'S AS SOON U COME ACROSS THEM. I BELIEVE ANY ONE DOING MBBS-3RD YR OR ABOVE CAN DO THAT VERY EASILY.

plz put the reference if from outside KHURANA for there are often serious controversies regarding inclusion of some diseases under a particular D/D


EXPECTING A FAVOURABLE RESPONSE icon_confused.gif ,

THANKS A LOT icon_razz.gif icon_razz.gif icon_razz.gif
