Greetings,
The use of Pathology Assistants to do virtually all of the grossing of even complex pathology specimens, under the supervision of a pathologist is becoming commonplace in larger practices, and many are convinced it provides a more consistent, higher quality gross dissection and sampling, as long as the PAs are properly qualified, trained and supervised and have pathologist back-up.
Conversely, in most pathology training programs, the residents do most or all of the grossing as part of their training (sometimes with the exception of small biopsies). However, this is counter-intuitive from a patient safety standpoint: i.e. your least experienced people, who are interrupted by other concurrent responsibilities and rotate in and out on a scheduled bases are doing the part of pathology which is most critical to patient safety and can't be replicated if done wrong.
We are considering tweaking our program in some ways to improve patient safety in the gross room and reduce errors and would like to see what others do and think. The concept being tested is that more of the grossing of complex specimens should be done by PAs and experienced residents (not fresh trainees who are trying to learn all aspects of pathology and lab at the same time and are prone to
errors) and the training of residents should also include aspects of directing a gross pathology lab (which requires knowing how to gross, but also other things), rather than just grossing alone.
Could you help with the answers to these questions if you have a residency training program in pathology:
* Do PAs gross complex specimens?
* Are PAs involved in training residents or vice-versa?
* What is the salary for PAs who gross complex specimens?
* Do you have any other innovative ways to reduce gross room errors by residents in training or to teach gross pathology to same?

Dear All:
Just wonder anyone have worked on PSA_NCAM IHC of frozen sections?
How about 1:1000 mouse anti-PSA NCAM from millipore to stain 30 um brain sections?
And, do you need to add triton into the PBS, to "pore" the membrane?
I think PSA-NCAM is distributed on the cell membrane, thus PBS may work?
Protocol:
1. Rehydration. PBS
2. Mouse-anti PSA-NCAM 1:1000 overnight + Blocking simultaneously.
3. 3* PBS
4. Goat-anti mouse conjugated with 488 fluroscein
5. 3 * PBS
6. DAPI
7. PBS wash
8. mount
Any other comments on this?
especially the time & concentration for first antibody?
thx,

Hello all,
I wanted to get some feed back from anyone using Alcian yellow as opposed to Geimsa for staining H.Pylori. Right now we are using Gemisa for detection of H.Pylori, and are considering changing to Alcian Yellow. Just wanted your opinion of what is most preferred by the pathologists.
Thanks in Advance

Hi everyone,
We occassionally get blocks from outside labs that use alcohol as the fixative. Our pathologist told me that our immunos look pretty bad when we handle these cases in the same manner as our routine FFPE cases. He is most concerned with Ki67 and K/L. I tried them with no antigen retrieval but got no staining at all. Any thoughts? We only do derm.
Thanks,
Erin

Subat:
Here is my manual protocol for mouses tissues, that
works very well for all mouse tissues (thickness no
more than 3 mm):
1. Isopropanol 70% 30 min
2. Isopropanol 80% 30 min
3. Isopropanol 95% 30 min
4. Isopropanol 99% 30 min
5. Isopropanol:Mineral oil 5:1 50oC 60 min
6. Isopropanol:Mineral oil 2:1 50oC 60 min
7. Mineral oil 1.5 h (or overnight)
8. Paraffin 60oC 30 min
9. Paraffin 60oC 30 min
10. Paraffin 60oC 20 min
11. Paraffin 60oC 20 min.
Advantage of isopropanol consists in that ethanol
have "tide" effect and do tissues hard, but
isopropanol (IPA) not.
Mineral oil = paraffin with low molecular weight
and the infiltration is better and gentle. Mineral
oil is absolutely not toxic for personnel.
Transitions between IPA, MO and paraffin are very
gentle.
Please let me know about results.
If you need any more details please contact to me.
Best wishes,

HI Erin. The best situation would be you could speak with this client, and
persuade them to use formalin, too. Let them know your IHC protocols are
optimized for FFPE (probably H&E's would look better, too). If this doesn't
work, obtain some alcohol fixed control material and optimize your IHC for
this material, too. You will need to try a variety of pretreatments &
titers. In essence you will have 2 protocols for your IHC - 1 for FFPE & 1
for alcohol fixed. What fun! Good luck with working all this out.

You can buy the staining kits from Master Tech and probably Newcomer's or
Poly Scientific certainly easier than making it up, plus kits come with
directions. I belive staining protocols have been posted on Histonet
several times - you can check Histonet Archives

Are they using pure alcohol for fixation? I do IHC for a dermpath lab that uses alcoholic formalin and their tissue stains very well. The only difference is we have had to cut-back on our antigen retrieval for certain proteins.

Hi everyone,
We occassionally get blocks from outside labs that use alcohol as the fixative. Our pathologist told me that our immunos look pretty bad when we handle these cases in the same manner as our routine FFPE cases. He is most concerned with Ki67 and K/L. I tried them with no antigen retrieval but got no staining at all. Any thoughts? We only do derm.
Thanks,
Erin

Does anyone have the Pslim slide labeler from AccuPlace.
http://www.accuplace.com/PSLIM.asp It sounds really nice for our work
environment, but I'd like some real world feedback.

Hi,
I am pretty new to staining (as in i have only ever tried it once) and would
appreciate any help you can give me with regard to processing my tissue and
staining. I will be processing mouse brains in the coming weeks with the
intention of staining for amyloid, and want to check about the correct
method for fixing this tissue. In our lab, we have always snap frozen tissue
in OCT directly after taking it, no sucrose gradients or aldehydes
etc.However, i have noticed from reading the literature that most labs seem
to fix the tissue in 4% paraformaldehyde before fixing in paraffin. Does it
make any difference as to which protocol is used? I am reluctant to change
unless i have good reason to. I am planning on perfusing the animals with
PBS before taking half the brain for immunohistochemistry (in OCT) and the
other half for ELISA/RNA etc and so can't perfuse with PFA.
My other question relates to the staining for amyloid beta itself. I have
noticed that a number of protocols incorporate a step to treat the sections
with 70% formic acid prior to staining. Is this neccessary for the staining
of amyloid, and if so, what advantages does it offer.
Any help anyone can provide me with would be greatly appreciated
Thanks

Hello all,
I am wondering if anyone has had to change a Sakura Tissue-Tek Processor from counter top or side by side, to a up-right or stand alone. I have a very small lab and need to make room for a new processor and it will all fit if there is a way to change it. Any advise or info would be helpful.

Dear All:
Just wonder anyone have worked on PSA_NCAM IHC of frozen sections?
How about 1:1000 mouse anti-PSA NCAM from millipore to stain 30 um brain sections?
And, do you need to add triton into the PBS, to "pore" the membrane?
I think PSA-NCAM is distributed on the cell membrane, thus PBS may work?
Protocol:
1. Rehydration. PBS
2. Mouse-anti PSA-NCAM 1:1000 overnight + Blocking simultaneously.
3. 3* PBS
4. Goat-anti mouse conjugated with 488 fluroscein
5. 3 * PBS
6. DAPI
7. PBS wash
8. mount
Any other comments on this?
especially the time & concentration for first antibody?
thx,
2008-07-31

You did not mention the specific model number, but I believe that I can be
of help with this. I have done it before with the "K" & "E" series
processors.
Contact me "off-List" for more information.
