As for a lot of tests, the answer is a bit tricky and confusing, but D
is right: although the pathologist can see something that MIGHT be
fungus on the routine stain, (s)he will ask for a special stain (GMS or
other) to confirm the presence of fungus. Hence, D. Fungi are never
demonstrated with routine procedure. You will need the special stain to
be sure. This is true for most special stains: the pathologist sees
something on the routine stain, but it is not conclusive, so special
stains are needed to confirm the diagnostic.

Although my first thought was that "C" was correct, on second thought, I
think it probably is "D" as they stain the same color as the background
(counterstain) and therefore tend to blend in.

Terry,
You stated:
"PS The recurring problem of sawing bones drives me nuts. The
sawing bit is easy, you just need a saw, it's the holding of the bone
that's the problem."
Next time you are out shopping, pick up a melon ball device in
assorted sizes. They are perfect for holding a femoral head to guide into
the table top band saw or while using the Stryker Saw. They are also great
for holding irregular shaped bones such as clavicles, etc.
From the kitchen to the lab... :-)
Linda
PS: Now, if we could just figure out how to put those nifty stir bars into
our home cook pots so we would not have to stand and stir...hmmm!

ASCP study guide
Some of the questions that are in the HT/HTL study from ASCP are questions
that used to be on the exam but were removed because they did not perform
well for a variety of reasons. They did not differentiate between
knowledgeable candidates and others that did not know as much, or perhaps
there was more than one correct answer, but they still give the candidate an
idea of how the questions are written, etc. This question was probably
removed from the exam and is in the booklet for the same reason it is under
discussion now.

It's a poor question because the last choice is ambiguous. When you read "are never demonstrated" you naturally take that to mean "cannot be seen". However, we know that fungi can in fact be seen in an H&E section. Therefore they are "demonstrated" to some degree. But they are not specifically demonstrated in a way that makes them obvious against the background.

I disagree. An experienced pathologist will see and know fungus on an
H&E. He/She does not need another stain, billed to the patient, for
confirmation.

Mid-mitten Michigan. The way this weather system is moving, you may
yet see snow. (I like Canada, but I could do without the exports from
Nunavut and the Northwest Territories.)
And I only see the snow if I crawl up out of the dungeon where us EM
trolls are generally kept.

Ah, you guys have it WARM, so don't be wussies! It has been snowing here
all week. Come visit Montana where our annual Easter Bunny snowstorm only
dropped 8 inches heavy wet white UGH! this year (normal is ~ 2
ft!) Temperatures plunged to 20F - 25F with winds making the annual Easter
egg hunt a ear and nose snap freezing experience. The front yard mini
glacier should be taken out with Global Warming by end of week though.
Springtime in the Rockies is sooo much fun at times.

While I don't wish to seem an old petarder, most of the several emails
we have seen re bone saws have nothing to do with bone saws.
How about decreasing the amount of interpersonal chatter that is being
distributed to all on the Histonet so that we don't have to waste our
time with opening and deleting all these?
Thanks for your consideration

No, our positive control tissues are placed on separate slides. We will cut 15-60 slides at a time depending on how often the control is used and the target protein's stability.

Hi James,
I just want to mention that we do have some posters of all the paintings
that adorn our catalog that I can send to you. If you take a look in
our catalog (volume 7), page 79, it will give you an idea of some of the
posters. Some are rather interesting from different points of view of
featured artists (Picasso, Klimt, and Michelangelo). They might fit in
with your history presentation. If you find any of interest, I would
look into either getting you an image or the actually poster. Please
let me know.
Thanks,

As for a lot of tests, the answer is a bit tricky and confusing, but D
is right: although the pathologist can see something that MIGHT be
fungus on the routine stain, (s)he will ask for a special stain (GMS or
other) to confirm the presence of fungus. Hence, D. Fungi are never
demonstrated with routine procedure. You will need the special stain to
be sure. This is true for most special stains: the pathologist sees
something on the routine stain, but it is not conclusive, so special
stains are needed to confirm the diagnostic.
