[Histonet] RE: Histonet Digest, Vol 7, Issue 15
| From: | Dorothy.L.Webb@HealthPartners.Com |
Due to SO MANY requests for the CAP workload guidelines, I will type the
paper here as I have it copied. I cannot fax that many copies without
drawing attention to this by management!!! If there is anyone who
absolutely needs it faxed, I could do that. I hope this works out for all!
This was put out by NSH, received August 21, 2002 and printed as "CAP
WORKLOAD GUIDELINES FOR HISTOPATHOLOGY"
The College of American Pathologists (CAP) Laboratory Management Index
Program (LMIP) has provided the following workload guidelines for the
delivery of quality slides. NOTE: Only the actual histology slide
production and grossing area workload for histologists and laboratory
assistants are included. The counting for the production of a slide
includes accessioning of the specimen assisting during grossing, any work
involved in processing (programming, changing solutions on the processor,
etc.), embedding, sectioning, routine and special staining (including making
solutions and cleaning up), coverslipping, performing any recuts, as well as
filing and retrieving. No cytology prep, autopsy prep, or clerical
functions other than accessioning is included.
Each well trained histologic technician or histotechnologist can be expected
to produce approximately 3000 slides per quarter, or 12,000 slides per year.
Included in these totals are 2500 H&E stained slides and 500 of the common
special stains per quarter, or 10,000 H&E's and 2000 special stains per
year. If only rare special stains are requested, more set-up time is
required. 12,000 slides per year is equivalent to approximately 50 slides
per day. These are average numbers for a lab where much of the work is not
automated. Most labs produce about 40% more slides than blocks, including
recuts.
EXAMPLE: A large laboratory, producing about 60,000 slides per year, would
be well advised to staff it with five(5) histologic yechnicians and/or
histotechnologists plus two(2) laboratory assistants. This staffing allows
for days off, vacations, and sick time. Supervisory duties can be delegated
to one staff member or split between them, with supervisory personnel
assuming about one-half of the technical/bench duties. Filling in for
missing personnel and helping on especially busy days should almost fill a
supervisor's quota for technical duties in any large laboratory (60,000 plus
slides per year). Included in supervisory duties are personnel management,
quality assurance, budgeting, requisitioning of supplies, some risk
management, and major troubleshooting.
The laboratory assistants should be able to assist the pathologist at the
grossing table; file and retrieve wet tissues, slides, and blocks; maintain
the tissue processor according to established protocols; and restock
supplies. Filing and retrieval has become increasingly important in the age
of second opinions and reviews of patient's previous surgeries.
In a non-automated laboratory, 50 slides a day (H&E stained sections,
special stains, and recuts), sounds like a reasonable workload, but, any
problems encountered can dramatically reduce an individual's ability ro
perform at that level.

OOOPS. I made a big boo-boo. I stated earlier that in my CPV protocol
there was no need for Antigen retrieval. That was only according to
the US Biological if using their ab. The VMRD ab reference cited calls
for Proteinase K, 5 minutes at RT.

Hello Netters,
I have a question that came from an investigator at my institute:
Can mouse brain that has been snap frozen in liquid nitrogen (stored
at -80 C degrees) be thawed and embedded in OCT for cryosectioning
without causing excessive damage? How can this be done?
I appreciate all of your answers and thank you all in advance.
Take care,

I don't think it will be entirely free of artifact but we have done
successful thawing/fixation then processing as described.
To thaw, just drop the frozen brain into formalin, it will thaw while
fixing, change NBF at least once to get rid of OCT and continue to let
brain fix, then process as usual.

It was my error in specifying 5% sucrose, but if you had done the Perfusion
One procedure with 10% sucrose prewash (isotonic, or slightly hypertonic),
and 300 mm Hg, you would have seen no shrinkage, and negligible ventricular
distortion. I have done it.
Please do not hesitate to try again. You have used enough pressure to fully
wash out the red blood cells, so you have seen the clean tissue and thorough
perfusion. You can also get the unshrunk and undistorted effects. The
results you did get are fully predictable given the hypotonic prewash.
Cordially,

More precisions:
The catheter diameter varies with animal size. For a 35 g mouse a n° 4
cathater works well (inside diameter = 0.76 mm outside = 1.22 mm).
We used 5% sucrose (saccharose was a little french slipping in) in water ,
as you had suggested. Unfortunately I didn't check out if this was in fact
isotonic, so that is a mistake! We perfused 1 minute at 300mm Hg. The
histology looked bad, that is, the ventricles were dilated.
Another source advised us to use Mannitol at 25% for 20 " at 110 mm Hg.
This too created ventricle dilation.
For each trial 3 mice brains were processed, coronally sliced at the
hippocampal level and stained with H/E.
yours truely,
Nancy

I am the Histology Instructor at the local Institute of Technology. I am
currently in the market for manual microtomes. I have always used Leica
microtomes in the hospital and have been very happy with them. I am not
interested in motorized microtomes since repetative strain injury is not
usually an issue at this stage. What I would like is a solid,
bullet-proof, rotary microtome. These should hold up to years of student
use (abuse). I am replacing some 40 year old AO 820's that are still
working, but, only just barely. Any comments would be appreciated.
Thanks.

Hi Tom,
My facility is currently purchasing a microtome for our lab. The one that we
decided on in the end is the Microm HM 310. We are a small pathology lab in
Los Angeles, CA and have no need for motorized microtomes either.
The other microtome we were considering was the Leica 2125 RT and both
models
are very much similar. In fact, the few differences stem from the different
providers not the machine itself. One is from McBain Instruments and the
other
is provided by Mikkron.
If you would like, I can fax you the quotes that were given to me by each
company. On them you will find brief descriptions of each model. Let me know
if
you are interested.
Sincerely,

The way we thawed specimens at a lab I used to work for, is by putting the
frozen tissue in refrigerated PBS for a few minutes. We then patted it dry
on a piece of filter paper and proceeded with the OCT embedding. Of course
that's if you want your tissue completely surrounded by OCT. If not, you
can just mount it directly in OCT from the -80.

I have not used R&D's caspase-3, but I have worked with cell signaling

I personally find it easier to mount it directly on OCT from the -80.
In my experience, if you embed the tissue, the sections are more likely
to curl.

The way we thawed specimens at a lab I used to work for, is by putting
the frozen tissue in refrigerated PBS for a few minutes. We then patted
it dry on a piece of filter paper and proceeded with the OCT embedding.
Of course that's if you want your tissue completely surrounded by OCT.
If not, you can just mount it directly in OCT from the -80.

Subject: [Histonet] Embedding previously frozen brain
Hello Netters,
I have a question that came from an investigator at my institute:
Can mouse brain that has been snap frozen in liquid nitrogen (stored
at -80 C degrees) be thawed and embedded in OCT for cryosectioning
without causing excessive damage? How can this be done?
I appreciate all of your answers and thank you all in advance.
Take care,
Jo Dee

My thoughts exactly. Just place in the cryostat and let it warm up to
the cryostat temp and slice away. We always did brain frozen sections
this way.

I am a Lab Manager, not a Histotech, and I need your help. We are a general
pathology practice and need to know what kind of processing cycles others
use for small bx's. Currently our lab processes all tissues together, large
and small, and therefore has much trouble with over processed bx's.
I would very much appreciate your guidance so that I can help our histology
area move forward.
Thanks so much!

The concept of over-processed tissue crops up regularly.
Is there general agreement:
a/ That over-processed biopsies exist
b/ That they show some characteristic(s) by which they can be regularly
recognised
c/ That the cycle or some part thereof needs to be reduced in time to
correct the features seen in an affirmative answer to b/?

Can anyone recommend a vendor, etc. for CD138 (syndecan-1) that works
well on either the Ventana NexEs or the Dako stainer? Thanks in

Excellent question. You are quite correct that processing all tissues
together will create avoidable problems.
generally, needle biopsy or small endoscopic specimens can be processed with
as little as ten-fifteen minutes in each alcohol and xylene step. if your
processor has three or more paraffin steps, you can use ten or fifteen
minutes in each. Keep in mind that the first paraffin is frequently
contaminated with xylene so subsequent exposure of the tissues to "clean"
paraffin is key to good infiltration of the tissuesl We turn our "rush"
biopsies around in about an hour on the processor with about 5 minutes in
each step and still get very good results. It is important of course that
you have a schedule in place for the regular freshening or changing of
processing solutions.
Let me make you aware of a relatively new (year 2) proficiency program that
you may want to consider for your laboratory. Its called Histo-QIP offered
jointly by the CAP and the NSH. It assesses the quality of your histologic
preparations and stains using a variety of exercises the subscribing labs
submit for evaluation. You receive an assessment and detailed educational
material back that can be used to educate staff. Participation gives you a
good idea of what aspects of your operation may need corrective action AND
steps on how to achieve the quality you want. I participate on the
Histotechnology committee that developed the Histo-QIP program for the CAP
but I also enroll my lab because of my strong feelings for the program
biopsies processed on long cycles normally reserved for larger excisions
will be at risk for having protein-bound water removed, the effects of which
can be quite dramatic. These typically include pyknotic nuclei with very
poor chromatin detail. they are very dark and appear to be overstained..
overprocessed tissues may also be very difficult to cut.
