RE: [Histonet] Re:Gloves ..... a question

From:"Marshall Terry Dr, Consultant Histopathologist"

This post is difficult to understand. What on earth are cornified (I liked cornfield better) cells other than keratinised cells? Where would you most likely get lots of keratinised cells from, a lightly keratinised site or a heavily keratinised site? The mouth is, for the most part non-keratinised, and is therefore not in contention at all as a site of origin.

Let me confirm that it is sometimes a problem.  I feel sure that there are either shedders and non-shedders, that there are someday shedders and other day non-shedders (if you see what I mean).

When I was in NZ a few years ago, it was a really bad problem, solved by getting the tech to wear gloves when labelling the slides. Slides are invariably labelled with the writing right way up, frosted end pointing North. This means the fingers and heel of the hand rest on the slide. That is the source of the squames.

I also have never worn gloves for embedding or cutting paraffin processed 
material although I can see the merit of wearing gloves when cutting 
unfixed frozen material. I was also intrigued by the comments about dead 
skin cells occurring on slides. It is highly unlikely that you would ever 
identify the fragments of keratin that might be shed from your hands when 
cutting sections; you just would not get cornified epithelium shed from 
the hands or scalp because these sites are heavily keratinised. You are 
much more likely to get the cornified cells deposited on slides from the 
mouth, by breathing on the block whilst cutting or onto the slide whilst 
cleaning. I have also noticed that there are times when deposited 
cornified cells increase to problem levels and this often coincides with 
the microtomist having a cold or a sore throat. I strongly feel that the 
notion of cornified cells from the hand/scalp is a myth that is passed 
from generation to generation often by practitioners who should have given 
it more thought.

I have never worn gloves and I have never had a pathologist complain of 
skin cells on my slide either.

I once had a pathologist complain dead skin cells on  his slides when he 
that I did not wear gloves when I was cutting.  Anyone else ever hear this 

from a pathologist?
