French to English Medical Medical (general) letter

Good evening,

This might be a stretch...

This is part of a letter heading.

At the top we have the recipient's name and address
Then,
Information regarding the senders
(Initials of both senders - doctor and resident)
Then,
D.M.: [redacted]
Then,
Received on x date (happens to be the discharge date)
Then,
Concerne:

And then the letters begins with Chers confrères

Since the information after "D.M." is redacted, I was thinking it must be something typically redacted, but I'm drawing a blank.

I'm hoping I'm missing something simple!

Thanks for having a look...
