You may have mentioned this earlier, but I don't remember.  What do
your CT scans show?  As I mentioned earlier the ones done around my
home town have all come back fairly normal, but I later found out they
were limited.  I was diagnosed with the osteomyelitis from a detailed
scan that I had at National Jewish Medical Center in Denver about a
year and 1/2 ago.  It showed "mild" chronic ethmoid sinusitis with
reactive bone formation.  The reports I first received did not mention
osteomyelitis and no one there mentioned it either.  I only found out
when I requested a CD with a copy of the CT.  The report that I
received with it mentioned the possibility.  That's what I took to the
ID doctor in Atlanta.  I have since found out that reactive bone
formation is most likely indicative of bone infection.

That's why I now get copies of all reports and the actual scans to take
to my doctor.  I even obtained a photograph of one of the cultures.   I
think a lot of doctors underestimate the pain and suffering that a
person with chronic sinustis has.
BTW, have you ever had brown or orangish looking mucus?  They can be
indicative of a fungal infection.

  I was on IV Timentin for 2 months.  This antibiotic was used because
of the heavy growth of Stenotrophomonas in my sinuses.  I had not
responded to oral Bactrim, which  usually treats this.  It is about the
only other option.  I had also had heavy growth of Serratia marcescens
before that.  If you do a search for either of these on the internet,
it relates them both to chronic sinusitis.  Now I am on IV voriconazole
(Vfend), a new antifungal.  I had blastomyces and Penicillium cultured
out also.  My current ID doctor says we will switch to nasal sprays
after that.
  I think I may have gotten the steno from using so many oral
antibitoics and  then picked it up because I wasn't boiling the water I
use in irrigation.  This bacterium is waterborne and can even be found
in bottled water and antibacterial soaps.  It usually doesn't cause a
problem, but I had also been on low dose prednisone for several months.
Before that I had used several antibitoic sprays including gentamycin
and at one point nebulized tobramycin.   I got worse after that.  I've
read that the use of these last two can cause selection for the
Stenotrophomonas.
  I have no idea how I got the blastomyces, but it is considered a
true infection and you have to inhale it from contaminated soil.  I
also worked in an extremely moldy school for a number of years that had
organic debris growing on a leaking roof.  I think that mold may have
been the problem all along and taking so many antibitoics made it
worse.
   The ID doctor I am now seeing believes pretty much in the Mayo
Clinic theory, but treats chronic sinusitis more aggressively.  He says
you have to get rid of both the bacteria and the mold to get better.
He also says that fungi are difficult to culture out sometimes.  I know
that this treatment is pretty drastic, but I have been so sick I have
wanted to die for over 2 years.  This was my last hope.    I took oral
Diflucan several times with no relief.  I also used nebulized
Amphotericin at one point and did improve, but went back to work in the
moldy environment 2 years ago and haven't been well since.  I haven't
been on the IV Vfend long enough to know if it will work.  At first I
felt terrible, but the last couple of days have felt better.
   I also know that most people won't need to be treated this
drastically, and I wouldn't recommend it but as a last resort, because
there are several risks involved. That's why I keep emphasizing that
people keep pressing to get a correct diagnosis early on.  Of course
doing that sometimes is very difficult as you probably know.
   You didn't ask for all of this information, but I just kept
rambling on.  Sorry, I just needed to vent to others who understand,
even if they don't agree with my approach.
