NSH has an archived webinar: Nuclear Bubbling: It's About Time" created by Peggy Wenk. The webinar talks about several causes of nuclear bubbling, changes that can be made to reduce this problem, and, for really bad cases, Peggy talks about how to dry the slide differently, reprocess tissue or use a HIER technique to improve the quality of the nuclear detail.
It's available to members through our online community: The Block: theblock.nsh.org

Hello All,
I manage a histology Dermpath lab (We only process skins) and we use Sakura X120 Processors. We have been doing excellent with the use of our x120 processors that allowed use to have slides on the Pathologist desk within 5 hours from the time we received the specimens. That said, there is always room for improvement! As anyone who uses the Sakura x120 Xpress processors know, all of the solutions and reagents required are "proprietary" so I don't know exactly what is in them. To top that off, we bought the processors from a 3rd party vendor, so Sakura isn't too quick to come out and help me with this. All of That noted, the reason I am sending this email is because I want to incorporate the pre-processing fixative because the specimens we receive in the afternoon haven't been in formalin as long (3-5 hours) as the specimens that we receive by mail in the morning (in formalin for 18+ hours). Our preprocessing solution is working ok, but I read in the user manual about preprocessing fixative that should be used instead, if the specimens were not completely fixed before processing.
Here are a few details of our current processing workflow with only using preprocessing solution.
* When grossing we have 3 small stirring hot plates set at 38 Celsius. Each stir plate described below
o 1 for the 0.2 or < Biopsies filled with 10% NBF prior to preprocessing solution for 15 minutes then processed on standard (1 hour program)
o 1 for the 0.3 or > Biopsies Filled with Statfix (statlab) Must be in statfix. Cassettes must be in for at least 30 minutes prior to preprocessing solution (30 minutes) Then Placed on the processor (Extended - 2 hour program)
o 1 for the excisions, Cyst and all other fatty skin specimens, filled with statfix Cassettes must be in for at least 1 hour prior to preprocessing solution (30 minutes) The placed on processor (Extended - 2 hour program)
I tried the preprocessing fixative (no heat, just stirring agitation) on test excisions and it definitely made the tissue more firm, (almost too hard) for 30 minutes. We had to use preprocessing solution for 1 hour on excisions, so that is a 30 minute improvement. It also turned the tissue yellow, which was weird. Before I try to test more tissue, I wanted to see if anyone else has went through the same preprocessing fixative testing with skins.
Questions Finally! ;)
* Does anyone use the preprocessing fixative for skin specimens and would you mind giving me some insight/advice on how to incorporate?
* Is it ok to incorporate any heat to the preprocessing solution or preprocessing fixative to speed up processing time?
* Does the preprocessing fixative affect IHCs any differently than the preprocessing solution?
* Does anyone have any comments/ideas about my inquiry?
I apologize for the lengthy post. Thank you for taking the time to read it. I hope everyone has a blessed day!

If I remember correctly, this issue has been discussed previously.The general consensus as to the cause of nuclear "bubbling" (in reality a lack of staining in the nuclear area) has been attributed to an incomplete section drying.After the section has be "fished" from the water bath, if the slide is not set to drain the underneath water before drying, the nuclear components are dissolved hence when the section is stained, there is nothing to stain ? "nuclear bubbling".I think this has been previously stated so I really do not understand posting this same question again.I do not think that posting again the question a different answer is going to be received.ren?

Deanne,
I purchase 5 liter cubes from Mercedes Medical.
They can provide test results on each batch of water and fax to you.
I did have a CLIA inspector advise to document daily on the water as is
written on the cube for clarity of water, no sediments or signs of contamination.
Think 5 Liters is about $12.50 and I use a little less than two a month.

Fellow Histonetters,
Our medical center will no longer be providing us with water for our laboratory procedures.
I was wondering where other labs who need to purchase Clinical Laboratory Reagent Water are doing so?

Anybody have an idea where we can get a used cassette basket that will fit in the VIP 6? The cost of a new one is pretty high?

Hi all... Hoping you might be answer a couple of questions that I have. 1) Does anyone use a microtome knife sharpening kit made by Pathco?
If so, 2) How well does it sharpen the blades? 3) Is there any issue on attaching the abrasive sheets to the honing plate? 4) Do the abrasive sheets tend to "move"
during the sharpening process, that would cause the blade not be on them but on the plate instead?
I currently am using coarse and fine abrasive liquids along with the honing plate... but the coarse, fine and honing liquids are becoming quite expensive and hard to come by.
Any and all replies are welcomed.
Thank you in advance,

Deanne,
If you just need it for a few critical reagents You can get type 1 water by the pint or the gallon from Fisher (NERL Type 1 water). It's probably overkill for most histology procedures, but convenient if you need it. Note that the expiry clock of 30 days starts when you open the bottle.

Struggling to find an answer. We do a lot of GI biopsies in our lab. Sometimes they look wonderful without any nuclear bubbling, other times the bubbling is pretty intense. Since nuclear bubbling is often attributed to incomplete fixation we of course have investigated the fixation times. I do not find that the problem is fixation. In fact some of the biopsies end up fixing for 48 hrs before processing. (weekend). There was a suggestion last week or so that there might be water trapped under the slides after cutting and before staining. I really thought that this might be the issue however I'm not sure at this point. Extra drying seems to help but sometimes slides side by side are so variable, one with bubbles and one without.

There is no need to be rude. He has tried the drying option and is still
having nuclear bubbling. He is exploring other possible issues. You

Subject: Re: [Histonet] Nuclear Bubbling
If I remember correctly, this issue has been discussed previously.The general consensus as to the cause of nuclear "bubbling" (in reality a lack of staining in the nuclear area) has been attributed to an incomplete section drying.After the section has be "fished" from the water bath, if the slide is not set to drain the underneath water before drying, the nuclear components are dissolved hence when the section is stained, there is nothing to stain ? "nuclear bubbling".I think this has been previously stated so I really do not understand posting this same question again.I do not think that posting again the question a different answer is going to be received.ren?

Dear James:
Two chained events take place on your issue:
1-sections not entirely drained,water remains even minimally under
sections;
2- you put these sections in the oven, the heat literally "explodes" the
nuclear bubbles and creates a hole with no cromatin to stain.
My kind regards,
Carlos Defeo

I don't have your answer Jim, yet I can vouch for your experience as a
supervisor since you were my boss for about two years. Hopefully you can
get it resolved because it can be very frustrating as the tech.

Good Day Everyone,
I am looking to obtain used Thermo Sequenza Immunostaining Racks (about 10 or so). Does anyone have any that they would be willing to part with?
Please feel free to contact me directly.
Thanks in advance!

Does anyone have a policy that they are willing to share regarding tech errors, error prevention, etc?
How do you document, retrain, write up, and terminate employees for errors? What is considered severe problems for termination, etc.
I know it is up to the manager, I want to know what other lab standards are to help create a procedure.
Thank you,
