Now add in a few other things, that I didn't directly mention in the
original 2006 HistoNet reply.
How many people are now using:
- automated H&E stainers
- automated special stainers, including IHC stainer
- automated coverslippers
- automated microtomes
- disposable blades
Can you see why nearly everyone passed the practical? If they could cut a
half-way decent section (with better microtomes and blades, easier to do),
just put the slide on a machine and let the machine stain it. To fail, they
basically had to NOT follow a LOT of directions, such as submitting colon
for small intestine, submitting autolyzed gall bladder, doing the wrong
stain (like doing a Prussian blue for iron, instead of the requested
colloidal iron), grossing the tissue too small, microtoming too thick,
putting the institution's name on the label, etc. Automation makes it easier
to produce better sections and better stains, particularly if someone is a
mediocre tech to begin with.
As to whether the person understands the theory when using automated
stainers - well, the fact that many of the people submitting the practical
could pass the practical but would fail the written - that has been going on
since "ancient" times, when staining was done by hand. They could follow the
directions, but didn't know the reasons. Pour on solution A for 5 minutes,
pour it off, pour on solution B for 10 minutes, rinse it off, and it's done.
No idea what is in solution A or B, or what chemicals are binding to what
components in the tissue, etc. Whether someone is doing the stain by hand or
by machine, it's up to the person to have the curiosity to find out what is
going on. Some people don't have it, and don't feel the urge to learn.
That's one of the reasons I like going to state and national meetings, and
reading HistoNet. These people WANT to learn! Hurrah for them! And there are
a lot of people in the histology community willing to help people who WANT
to learn - answering HistoNet, giving talks at state and national meetings,
being a mentor, etc. Hurrah for them too!

The dropping of the practical was explained so well by Peggy Wenk. I
never got into the debate(glad I did not after reading Peggys
comments), I would have argued to keep it. That said, indeed it is
outdated. The fact that we were the last to do it I guess speaks
volumes. I did struggle getting tissues for it for sure. Modern day,
modern thinking. Thanks for the information Peggy and of course all
you do fo this field.
