We always photographed them asap and then got rid of them, they do fade and
take up space in the fridge.

Hello everyone,
This question might have been posted before, but, Histology Department is
expecting a brain biopsy from a possible CJD patient today. The specimen
will be coming down in formalin from the O.R. It will be kept in formalin
for 2-7 days and will be transferred to formic acid for the required time.
Then the specimen will be transferred to formalin before processing for
another 2 days. Has anyone dealt with this procedure before. These are the
questions asked by the hstology department.
How do you decontaminate the processor, microtome, stainer and
coverslipper?
What kind of protective gear apart from standard precaution has to be used?
How about the shaving of the tissues?
How do you dispose the formalin from the original formalin container where
the specimen was sent in and how do you dispose the reagents from the
processor and the stainer?
Can this biopsy be processed, once treated with formic acid, along with the
other specimens or should the biopsy be processed with the other
specimens?
Need Help!!
Thank you in advance

You may have heard that classical music was composed by dead white
Europeans. Well, Harris hematoxylin was composed by a dead white American
(physician at Jefferson Hospital in 1904). Gill hematoxylin was composed by
a live white American. So if you want to liven things up, go with Gill's!

Wow. What a lot of interesting comments!!
I agree with Terry re the agitation. When I watch the stainer do those dips
(I can program how many, but NOT the briskness), I wonder if you could even
call it agitation. My hand dips are very brisk. Also, I don't bother
letting the slides stay in the alcohols for 1 minute or 2, I give the slides
about 20 -30 good brisk dips in each solution, then the timed rinses &
staining. This has always been far more satisfactory to me than those
sllllooooowwwww dips from the machine.
As for the kind of hematoxylin, someone suggested I throw out the Harris and
do Gills III. I've tried Gill III before and I much prefer the Harris. So
it's just a matter of personal preference on that... AND what your
pathologist likes *G*
Everyone having an nice Tuesday??? *g*

Connie remarks:
"In truth, I prefer my hand stained sections better than when they're
stained automatically."
When I first saw what I call x-y stainers, I thought that we had in this,
something that reproduced hand staining. Not so. What I think is lacking is
the brisk agitation necessary to break down the interface between old and
new solution. I'm not so sure about the rinsing either.

We use almost the exact same protocol... we use Surgipath Harris, but we
prepare eosin in-house. One thing I am amazed at in this protocol is the
length of time in the acid alcohol. Do you use an autostainer? We have a
Leica. The time is set to 1 second in the acid ETOH and
sometimes the sections are almost too differentiated. I can't imagine
6 seconds in the acid ETOH!! Even when I do H&E manually, I dip the slides
in and quickly put them in running water. I must have a very strong
solution, I guess. Hmmmm. Interesting. In truth, I prefer my hand stained
sections better than when they're stained automatically.
Just wondering and blabbering (hey, it's Tuesday, what do you expect??)

The WHO booklet was too large to send as an attachment so it couldn't be
delivered. I will try and send you what I think is the most relevant
chapter. Perhaps you could visit the WHO site and get more information
if needed. In the meantime, the Surveillance Center link below should
have enough information.

Hi Histonetters!
Our veterinary lab is in the process of up dating our research charges. I
would like to know what other labs/hospitals charge for H & E bone slides
and H & E eye slides. Currently we are charging, Bone: $19.00 for
decalcifying in 25% formic acid, process, embed, sectioning and H & E
stain. We are losing money on our larger bone projects. Our charges for
processing, embedding sectioning and H & E stain for eye slides is $9.00.
It also depends on the project rather or not we make or lose money. The
researchers do their own grossing of tissue. Any help would be greatly
appreciated! Thanks in advance.

Ahhhhh working with a beer at my elbow. Sounds very sane to me.
I think we got one of your country women..a Wealthal..up for a phd.
She denies dwarf tossing, but I have heard things to the contrary.
I have two square carts with drawers in used in the dental school.
They have wheels on them. I put the microtome on one and the waterbath on
the other. They sit side-by side with a space between. They are just
high enough for me to use a standard height chair with wheels and move
back and forth between them. It is the best arrangement I have found. I
can get up over the water bath to get a good look at what is going on. I
really like it. Not hard on the back like benches.
Would suggest it for those having problems with benches and sitting still
in one possition.
If I can figure out how to put an ice bucket for the beer between, we's
really have something.

We stain our Congo Reds on an automated stainer now. Before that we
stained with hematoxylin first because rinsing and differentiation was
required and we used an alkaline Congo Red. After staining with the
Congo Red in a saturated sodium chloride- alcohol solution,we did not
rinse,but rapidly dehydrated, cleared and mounted
For our H&Es we use Modified Harris Hematoxylin and Eosin-Y w/
Phloxine both manufactured by Richard Allen.

Diane,
We charge one price across the board, $5.50 if the tissue is received in a
cassette and $2.50 if it needs decalcification. Our philosophy is that we
don't charge less for simple specimens, so why charge more for occasional
complicated ones? Of course if it's a large project consisting of many whole
eyes or femur heads, I'd probably double our current prices to cover for the
additional labor and material.

Hi Histonetters!
Our veterinary lab is in the process of up dating our research charges. I
would like to know what other labs/hospitals charge for H & E bone slides
and H & E eye slides. Currently we are charging, Bone: $19.00 for
decalcifying in 25% formic acid, process, embed, sectioning and H & E
stain. We are losing money on our larger bone projects. Our charges for
processing, embedding sectioning and H & E stain for eye slides is $9.00.
It also depends on the project rather or not we make or lose money. The
researchers do their own grossing of tissue. Any help would be greatly
appreciated! Thanks in advance.

The sizes are minimums as you understand. You will be held strictly
accountable for ensuring that the tissue you submit in your block must
exceed the dimensions listed and that the tissue on the slide must match the
dimensions in the block (without excessive spreading from overfloating on a
warm water bath). Remember to allow for shrinkage during processing when
you are acquiring your tissue when fixing in formalin and using standard
processing. To get 2.0 cm of duodenum into the block you may have to cut
2.5 cm from the source tissue depending on your processing schedule. But
1.9 cm will not due. Also, if they specify 2.0 cm of duodenum with
epitelium along one side, they mean complete uninterupted epithelium in
perfect condition, perfectly fixed, perfectly processed, perfectly cut, and
perfectly stained. Any flaws will cost you points. I don't mean to be
negative just to remind everyone preparing for the practical that you must
pay attention to all the details. Read the directions very carefully and
follow every picky detail that they specify. A significant part of the exam
is the applicant's ability to follow written instructions accurately.
(Meaning, if they say a square, I'd recommend a square.) Pay attention to
the labeling of your slides. Be sure your labels are clear and readable
(typed), labeled exactly as instructed, and that your label material is in
good condition (stays on the slide, no curls or peeling, etc.)
Hope this helps, good luck.

Why are you handling this processing? The CJD Surveillance has been set up
by CDC to do all this work for you and also provide a diagnosis. If your
pathologists choose to do this themselves, be aware of the protocols which
can be found at www.cdc.gov and also the WHO website.
The biopsy should be handled in a level 2 facility. You need to wear gloves
and face shield. All processing and staining is to been done by hand in
individual containers which will be incinirated on completion, otherwise
you will have deal with the demanding work of decontaminating the processor.
All waste is incinerated.
You will find all this info at CDC website. Also refer to
www.cjdsurveillance.com if you decide to let the CJD Survellance do this
for you. Free of charge.

Is Gill a relative or yours??? I don't give a hoot who made what when.
I like Harris. I don't believe Gill has made any significant
improvements over the old dead white guy's hematoxylin.
BTW, classical music may have been composed by dead white guys, but I
don't hear ANYTHING being composed today that has the depth, complexity
and color of those great composers. I've studied piano from since I was
4 yrs old, and I've studied the organ (I've played as a church
organist)for almost 20 years. I know music like the back of my hand
and I love ALL music (except gangstah stuff). SO DON'T try to tell me
about what music is living and worth my while.
Dead white Europeans. Yeah, right. I'd like to see someone between 8 and
14 in this generation compose music like Felix Mendelsohnn's or
Mozart's.

You may have heard that classical music was composed by dead white

(physician at Jefferson Hospital in 1904). Gill hematoxylin was
composed by
a live white American. So if you want to liven things up, go with

Wow. What a lot of interesting comments!!
I agree with Terry re the agitation. When I watch the stainer do those
dips
(I can program how many, but NOT the briskness), I wonder if you could
even
call it agitation. My hand dips are very brisk. Also, I don't bother
letting the slides stay in the alcohols for 1 minute or 2, I give the
slides
about 20 -30 good brisk dips in each solution, then the timed rinses &
staining. This has always been far more satisfactory to me than those
sllllooooowwwww dips from the machine.
As for the kind of hematoxylin, someone suggested I throw out the Harris
and
do Gills III. I've tried Gill III before and I much prefer the Harris.
So
it's just a matter of personal preference on that... AND what your
pathologist likes *G*

When I first saw what I call x-y stainers, I thought that we had in

something that reproduced hand staining. Not so. What I think is lacking
is
the brisk agitation necessary to break down the interface between old

new solution. I'm not so sure about the rinsing either.

We use almost the exact same protocol... we use Surgipath Harris, but we
prepare eosin in-house. One thing I am amazed at in this protocol is
the
length of time in the acid alcohol. Do you use an autostainer? We have
a
Leica. The time is set to 1 second in the acid ETOH and
sometimes the sections are almost too differentiated. I can't imagine
6 seconds in the acid ETOH!! Even when I do H&E manually, I dip the
slides
in and quickly put them in running water. I must have a very strong
solution, I guess. Hmmmm. Interesting. In truth, I prefer my hand
stained
sections better than when they're stained automatically.
Just wondering and blabbering (hey, it's Tuesday, what do you expect??)

about 20 -30 good brisk dips in each solution, then the timed rinses &
staining. This has always been far more satisfactory to me than those
sllllooooowwwww dips from the machine.
As for the kind of hematoxylin, someone suggested I throw out the Harris
and
do Gills III. I've tried Gill III before and I much prefer the Harris.
So
it's just a matter of personal preference on that... AND what your
pathologist likes *G*
Everyone having an nice Tuesday??? *g*

Connie remarks:
"In truth, I prefer my hand stained sections better than when they're
stained automatically."
When I first saw what I call x-y stainers, I thought that we had in
this,
something that reproduced hand staining. Not so. What I think is lacking
is
the brisk agitation necessary to break down the interface between old
and
new solution. I'm not so sure about the rinsing either.

We use almost the exact same protocol... we use Surgipath Harris, but we
prepare eosin in-house. One thing I am amazed at in this protocol is
the
length of time in the acid alcohol. Do you use an autostainer? We have
a
Leica. The time is set to 1 second in the acid ETOH and
sometimes the sections are almost too differentiated. I can't imagine
6 seconds in the acid ETOH!! Even when I do H&E manually, I dip the
slides
in and quickly put them in running water. I must have a very strong
solution, I guess. Hmmmm. Interesting. In truth, I prefer my hand
stained
sections better than when they're stained automatically.
Just wondering and blabbering (hey, it's Tuesday, what do you expect??)

Hi,
I use Harris's hematoxylin which is also regressive and purchase my
hematoxylin and eosin /alcohol-based/ from www.surgipath.com. I get very
good H&E staining with this protocol.

I don't deal with CJD, but I do a lot of CWD (Chronic Wasting Disease)
and Scrapie, which are prion diseases in dear/elk and sheep
(respectively). CWD and Scrapie had been associated with humans for
hundreds of years with no known transmission of the disease from animal
to human. HOWEVER, since prions are not neutralized by fixation of any
kind, not killed by autoclaving, this makes them a biohazard in
processed tissues.
If I worked with CJD, I would ...
1 set up a place that is completely separate from the rest of the lab.
Barrier off a section of your lab, use another room (preferable)
2 use disposable bunny suits, shoe covers, face masks, eye wear and
DOUBLE GLOVE
3 put stickie mats on the floor completely surrounding the cutting
area,
4 put ALL paraffin shavings in a biohaz bag,
5 use paper towels to clean off the microtome and throw those in the
biohaz bag
6. incinerate the bunny suit, goggles, gloves, face maskes, etc with the
paraffin shavings.
7. Ask for a really big pay raise. Claim it's hazard pay.
Have fun.

Subject: [Histonet] CJD DECONTAMINATION PROCEDURE
Hello everyone,
This question might have been posted before, but, Histology Department
is
expecting a brain biopsy from a possible CJD patient today. The
specimen
will be coming down in formalin from the O.R. It will be kept in
formalin
for 2-7 days and will be transferred to formic acid for the required
time.
Then the specimen will be transferred to formalin before processing for
another 2 days. Has anyone dealt with this procedure before. These are
the
questions asked by the hstology department.
How do you decontaminate the processor, microtome, stainer and
coverslipper?
What kind of protective gear apart from standard precaution has to be
used?
How about the shaving of the tissues?
How do you dispose the formalin from the original formalin container
where
the specimen was sent in and how do you dispose the reagents from the
processor and the stainer?
Can this biopsy be processed, once treated with formic acid, along with
the
other specimens or should the biopsy be processed with the other
specimens?
Need Help!!
Thank you in advance
