[Histonet] toenails
We used to cut toenails by the hundreds and all we ever did was process on a routine processing cycle then embed as usual but on edge horizontally in the cassette. We put albumin on our slides to hold the nail on and stained them routinely. They were no problem once you got used to them.
Also, I agree with Hector concerning microwaves- I do as he suggested.

Jane Moose at Newberry County Memorial Hospital in Newberry, SC notes that she's been approved for a new cryostat.
This reminds me of a reason to replace old cryostats - they use the refrigerant gas R-12, which is no longer legal in the USA (though still available) because it's a prohibited fluorocarbon. The information as to what refrigerant is used is on the base plate of the cryostat.

Dr. Allen Smith's recent post reminds me of a question I've been meaning to post to Histonet.
Podiatrists are now performing biopsies of toenails with nail fungus, in order to get a fungal stain (PAS is being requested, I think) done. Apparently the insurance companies are now requiring a biopsy or culture diagnosis of fungal disease before they'll pay for the very expensive systemic drugs for nail fungus like terbinafine (Lamisil).
Is anyone on Histonet getting these requests? What protocols do you use to cut and stain these difficult specimens?

Dear Histonet,
I'm a molecular biologist working at the University of Cambridge, UK. I
was wondering if anyone could recommend a histochemical stain that would
work for cerebral blood vessels, preferably in frozen sections? I've
been trying alkaline phosphatase staining but with mixed results.
Would a collagen stain like Fast Green FGF work in isolation (rather
than as part of a trichrome stain)?
It doesn't need to be completely specific for vessels, as long as they
are clearly visible. The other point is that is needs to be as quick and
simple as possible, as I need to extract protein from the tissue
afterwards. Immunostaining is no good for this application. All
suggestions welcome as I will probably need to test several things to
find one that works.
Best wishes, Laura Harris

This question is for anyone who uses a Benchmark XT. We would like to
know at what percentages your pathologists prefer their controls. 11-25%
weak staining or do they prefer the ER/PR controls with a stronger

We usually go with stronger controls (scores of 12 out of 12 or slightly
lower). This probably isn't the best; an array of intensities would be
but no one is complaining.

I think vanGieson is the shortest collagen-stain. Staining with FGF or
Anilinblue alone would perhaps lead to an overall stain, more in the
collagen fibers less in the rest of the tissue.
These are links to the excellent pathopic-picture-archive. Perhaps you find
the right stain for your needs.

Hi Stacey,
My understanding is that this is N/A unless you are processing in your
microwave, or using other "dangerous" stuff. My lab is considering this not
applicable because we only use the microwave to heat water, and a few
stains. We don't heat Bouins, or any other fixative, dehydrant or clearing
agents. I can let you know how if this is acceptable after our inspection
that could be any time from now until May.

Greg:
The new CAP regulation stems from the fact that many labs used the "house microwaves ovens"(HMWO) also to fix and process tissues. That is where CAP, manufacturers and a MW task force intervened with the valid warning that fixing and processing, and even staining when the solutions are alcoholic, are unsafe procedures to be done in a regular
HMWO,and that those procedures really require an instrument with a venting capability that will take the noxious vapors out of the lab.
To just heat water or buffers for HIER I did that for many years and no inspector ever said anything. Perhaps they have become more demanding recently on this regulation, but for me there is nothing noxious to vent when only water, PBS or buffers are heated. In your house you also heat water and there is nothing noxious about it (and we are talking about the "sacred" home environment).
Just my opinion though!

Hi, everyone. I have a few questions I'm hoping you'll be able to help me out with. I have 10+ years doing immunohistochemistry on PFA perfused, frozen brain sections, but a few things I'd like clarified.
1) Does it matter whether one uses PBS with or without Mg and Ca for immunos? I have always done it with PBS without Mg and Ca, and have never heard of anyone doing it with Mg and Ca, but have recently encountered a scenario in which this was the only PBS available. Wondering whether this will make a difference in my staining.
2) Can anyone explain the need for dehydrating and defatting slides (after using such substrates as DAB for color development) before coverslipping? Aside from the obvious that the sections look pretty crappy without these steps, can anyone explain the science behind this?
3) Because my tissue is perfused, I typically store the brains in 30% sucrose (with a little bit of sodium azide) in 4 degrees, until I am ready to cut the blocks. At this point, brains are usually frozen in the cryostat just before cutting 40um thick sections. I have obtained wonderful staining and morphology with this technique, however I have been recently advised to store the brains embedded in OCT (or similar) in a -20 degree freezer, rather than in 4 degrees. I am skeptical and concerned that this will damage the morphology and produce that "swiss cheese" freezer artifact (you know, where there are all these holes in the tissue?) Can anyone provide any advice, insight as to the benefits and drawbacks to either/both of these methods?
Thanks everyone! Any advice, insight, comments are greatly appreciated.

Do you filtrate formalin before recycling? What filters do you use? How do you make buffered formalin after recycling- maybe do you have special enclosed system for buffer preparation?

Vilma:
I never recycled formalin and let me tell you why:
in the first place you BUY the neutral (buffered) formalin to avoid exposing yourself and staff to formalin.
If you recycle it you defeat the whole initial purpose because at the end you will end with formalin that YOU will have to dilute, that YOU will have to neutralize and YOU will end doing what you wanted to avoid in the first place.
Although it is expensive to dispose of formalin (via a specialized company) it is worth it!
At least that is how I saw the whole issue and decided NOT to recycle formalin.
With regards to ethanol I did not recycle it either because it takes TWICE the amount of time to recycle ethanol than to recycle xylene and is cheaper to dilute it and dispose it to the sewer system.
I only recycled xylene and my B/R recycled was paid off in juts 34 months.

Well, it looks like I am wrong about being able to use my microwave to heat
water, buffer, etc.... at least I checked and the Instruction Booklet does
say "not for laboratory use" in the Safety Instructions portion. See a
vendor's private message to me below (thanks, Donna).

Bonnie,
I decided to email you direct on this issue. Your onsite inspection will be
with the 2005 CAP regulations. They have changed as of Dec 2006 and your
next year self inspection will be with the new regs. The regs say that you
have to use the microwave according to manufacture guidelines. Household
units have in their warranty that they are for food processing, do not use
for laboratory use. This has always been an issue with OSHA but never
mentioned in CAP. CAP has changed and added the new question. OSHA 29 CFR
1910.303(b)(2) (listed or labeled equipment shall be used or installed in
accordance with any instructions included in the listing or labeling) has
always been an issue but rarely enforced. As far as OSHA is concerned you
should never use any piece of equipment out side of the manufacture listing.
This would mean no rice steamers in the lab for AR. I have put the new regs
in my workshop. I'll let you know the reaction of folks as I give them this
year.
Being a vendor I felt it would be better to just e-mail you myself instead
of everyone on the histonet. If you feel you want to post this to the net,
it is up to you.

ANP.29430 Phase 1
This question doesn't state laboratory or home grade microwaves. Microwave
should be placed in an appropriate ventilated hood to contain airborne
chemical contaminates and potential infectious agents. Microwaves used
outside a fume hood should have an integral fume extractor that is certified
by the manufacturer for use in a clinical laboratory. This doesn't say
microwave has to be laboratory grade, only the fume extractor. This
checklist question doesn't apply if only non-hazardous reagents are used in
the device (microwave) (e.g. water, certain biological stains)
In my opinion you can use any microwave (laboratory or house microwave) as
long as you can document:
1. Leakage is less than 5mW/cm2 at a distance of 5 cm from the surface.
2. Periodically monitor for temperature reproducibility.
3. All containers used in the microwave are made from microwave-transparent
material/ microwave proof.
Don't make it any harder than it is.
Hope this clears a few things,
Hector

Greg:
The new CAP regulation stems from the fact that many labs used the "house
microwaves ovens"(HMWO) also to fix and process tissues. That is where CAP,
manufacturers and a MW task force intervened with the valid warning that
fixing and processing, and even staining when the solutions are alcoholic,
are unsafe procedures to be done in a regular
HMWO,and that those procedures really require an instrument with a venting
capability that will take the noxious vapors out of the lab.
To just heat water or buffers for HIER I did that for many years and no
inspector ever said anything. Perhaps they have become more demanding
recently on this regulation, but for me there is nothing noxious to vent
when only water, PBS or buffers are heated. In your house you also heat
water and there is nothing noxious about it (and we are talking about the
"sacred" home environment).
Just my opinion though!

I am curious to know how labs have responding to the CAP Question
ANT.29430 which asks "Are microwave devices properly vented?".
Have the labs continued to utilized their regular "kitchen model"
microwaves and applied duct work to them to be vented out of the
building?
Please comment.

Hey Doc,
you have the South Texas Toenail lab guy right here. That's why I'm known as
"Joe the Toe".
We soak our nails in 20% ammonium hydroxide for at least an hour before
we put the blocks on the machine to process. We've been getting nailed for a
couple of years and perform a PAS for Fungus on each case that we do.
Reimbursement must be good, we keep getting nailed.

Hi Joe,
I guess the histology field still uses the old
methods. I was taught that back in 1974 at OHSU.
FYI-We also used soak in NAIR HAIR REMOVAL to soften
nails.

Going to put in my 2 cents, which may not be too accurate.
The FDA (Food and Drug Administration) covers topics that relate to Food and
Drugs and medical devices that go INTO a HUMAN BEING, and anything else that
touches these foods and drugs and medical devices that could effect a
person's health.
So as far as "recycling" would go, the FDA would be concerned about food or
drugs that were being gathered after NOT being used and "recycled" for reuse
(think of drugs after expiration date, or that had already been given to a
patient and returned back to pharmacy). The FDA is also concerned about the
plastic that goes around the food and drugs, as I remember they were
concerned about new "recycled" plastic that the food and drugs are packaged
in, and whether recycled plastic emit anything that would compromise the
food or drugs and make it a health hazard.
I know the FDA was concerned about medical devices (artificial hips, pace
makers, etc.) being removed from people, cleaned up, and "recycled" for use
in another person.
As for a xylene/alcohol/formalin recylcer - I personally think this is out
of the jurisdication of the FDA. The equipment itself does not go inside a
person, nor is the intended use of these chemicals that are being recycled
intended to human consumption. Neither the recycler nor the chemicals are
intended for human USE.
On the other hand,
- OSHA has lots laws about chemical exposure to people that would apply
- EPA would be concerned if the recycled chemicals got into the atmosphere
or the water, and care about the proper disposal of waste
- CAP has checklist questions for safety and use of equipment, electricity,
chemicals, disposal, etc. that would apply.
- I've never read the GLP, put I'm certain they have similar rules about
chemicals and equipment.
- Local fire marshals and the hospital's insurance company may have their
own concern, especially as to where the recycler is positioned - but this is
for scenarios of catching on fire and explosions.
If someone knows of the FDA's concern in recycling chemicals in the
laboratory, please inform HistoNet. Thanks.
