What criteria does everyone use to hire for working in your IHC department? I
am looking for feedback as to what qualifications are expected for IHC techs as
well as qualifications and expectations of the "lead" in IHC. Also, what title
do you have for the "lead" in IHC, technical specialist, coordinator, lead,
etc???
Thanks ahead of time for your information! We are trying to reinvent the
position and want to make it more like a community standard (community meaning
the world of histology)!!

We have routinely dried slides prior to coverslipping. We have found that
ethanol or acetone rinsing after staining shortens the drying time (in fact we
have used acetone to dehydrate MGG and DiffQuik stained smears, which must be
kept away from alcohols, prior to coverslipping).
Our automatic coverslipper uses a very runny xylene based mountant so we do not
need to rinse in xylene prior to coverslipping.
One paper we did describes the detergent de-waxing aspect and a study currently
in preparation applies the technique to fungal staining:
Henwood A (2012) "The application of heated detergent dewaxing and rehydration
to immunohistochemistry" Biotechnic & Histochemistry 87(1): 46-50.
It will depend on the staining method used as to whether you can use alcohol,
acetone or heat-assisted drying prior to coverslipping, but, dare I say, nearly
all stains can be treated thus.
Whoops, I forgot about the Oil Red O stains for fats, Oh well I did say "nearly
all"!!

Subject: [Histonet] RE: air drying special stain slides rather than
Ooh, great question for my students next semester.
Your answer is the counterstain, some counterstains may require dehydration
after rinsing, or some may not. Adjusting the times of the counterstain is not
the issue as much as the solvent of the counterstain.
Rene, while I do acknowledge that the xylene may/will cause hazards, we must
think of the miscibility of the clearant and the dehydrant, as well as the
amount of time involved. The amount of time involved to blot and air dry the
slides will affect the TAT for the specimen. 5 min may be ok if you have a
small amount of slides, but with a larger number of slides, it will be
considerably more than 5. Also Lean methodologies would not apply in that
case. With automation, the extreme heat involved with a stain dryer may affect
the tissue on the slide.
There are some stains that can be blotted, cleared and coverslipped, but using
the alcohol to remove excess water and counter stain is better in my opinion.

I was hoping to get information on why special stains are dehydrated, cleared
and mounted vs allowing them to be blotted dry, air dried then coverslip.
Every procedure I have ever encountered always indicates to dehydrate and clear
but I have heard where some labs are blotting the slides , allowing to air dry
(probably not set standard time) and dipped in xylene prior to cover slipping.
Reason given is that the counterstain gets washed out. Wouldn't adjusting the
times be a better resolution.
I understand residual water could be present and cause long term issues on
storage but wanted some other opinions on this process.

Diana:
The most simple answer to your question is: "Because that is the way it has
been done for more than 150 years".
The second question would be: "Is it necessary?" and the short answer to this
question is: NO!!!
As a matter of fact, one of the steps I have developed to totally eliminate
xylene from the histology lab refers to the "clearing" of stained sections, not
only "special stains" (the so called HC and IHC) but the routine as well (the
H&E).
Now, the "secret" to a successful drying of the stained slides is NOT to let
them air dry because that will take not only too much time, but you can never
be sure if the section is completely dry and if you add the mounting medium to
a not completely dried section, you will have transparency problems.
The correct way of doing that is by drying the stained sections during 5
minutes at 60?C in an oven.
Under separate cover I am sending you something I published about your question
and other aspects of how to completely eliminate xylene from ALL steps in the
histology laboratory.
Ren? J.

I am convinced to give it a try because I also have trouble will the loss of
some stains in dehydration.
I was concerned that the slides would not clear well after oven dehydration. I
will see how it works for me.
I can see clearly how going from counterstain to oven will save much hassle
with xylene and alcohols as well as not washing out some special stains. I
have tried some of the isopropyl alcohol and acetone dehydration called for in
some of the stain procedures and it would be great if the slides could just be
popped into the oven.
What mounting medium are you using? Does it matter? I am a bit worried about
penetration of the mountant into the tissue section if there is no xylene in
the tissue. Will neutral balsam still work ok?
Rene: if you have a link to the paper you talked about on eliminating xylene,
I am interested. Xylene is becoming more and more of an issue and a pain for
us.

Interestingly, I showed the results to a couple of colleagues.
One response was-
"The sections will come off!
The sections will come off!
All that heat!
The soap!
The sections will come off!
I don't think I even want to try That!
I'm going to stick with Xylene and Alcohols."
Another -
" Oh, this method is /Very Unusual/.
Maybe if the graduate students try to publish a scientific paper and say that
they used this method, their papers will be *Rejected* *by the Reviewers*."
"It's a published method. I have 2 published papers on it right here"
"Oh, so they can cite those methods in their papers. Ok."

We have been asked to look at changing our pathology reports over to the
synoptic report format. I was wondering if anyone could provide me some
information on voice recognition software for pathology and if this would be
the best (easiest) way to implement synoptic reporting for our path reports. I
am only vaguely familiar with both so any information will be of great use.
Thank You in Advance

Voice Brook seems to be the market leader.
They are powered by Nuance and Dragon which are the market leaders in the
consumer market.
However, they are pricy.
Nuance offers a service that is more similar to a remote transcription service,
however my guess is they rely heavily on their automated transcription
software, without the cost of purchasing the software itself.
If your IT department wants to dedicate 1 or 2 FTE's to getting you up and
running, a cheaper solution is to purchase the Dragon backbone from Nuance,
however it will take al ot of customization to make it on par with VoiceBrook.
Just my opinion.

Allison, it starts with what your objectives are:
If you simply want your reports to present information in a certain format,
then a word processor, optionally coupled with Dragon and optionally coupled
with Voicebrook will work.
If you need to send the data in it's individual components to another computer
system, then that's an entirely different story as it probably means that you
need to store the data discretely.
Either way, if you'd like to talk about it further please feel free to contact
me offline. Remember that I represent an LIS vendor, but since I love talking
about this stuff, I have no problem talking to you about it from a non sales
perspective.

For those with the Sakura Glas coverslippers, what type of mounting media are
you using in these? Sakura recommends only their brand of course, but I want
something that dries faster. We do not have excess mounting media on the
outside of our slides, but after being in the oven for three days we had
several slides sticking. It looked like the mounting media slipped down the
slide to pool at the bottom and stick. I am thinking their media is too
viscous. If I turn the amount down on the machine any further we end up with
not enough media on the slides and get large air pockets after just a few days
of storage. BTW the oven is at 40 degrees and isn't boiling hot to dry the
slides.
