ON THIS DAY IN HISTORY

TL 7-11 ON THIS DAY IN HISTORY

On July 11, 1985, Dr. H. Harlan Stone, head of general surgery at the University of Maryland Hospital at Baltimore, announced that he had used zippers for stitches on 28 patients in order to re-operate more easily.

Um…  to begin with, I didn’t even know they could use zippers instead of stitches.  I know there are various kinds of stitches and types of silk…  but zippers…  really???

At first glance, this sounds funny, but the more research I did, the more serious this got.

Pancreatitis is a fairly common condition for diabetics and when severe, requires surgery to remove inflamed or abscessed parts of the pancreas.  This produces internal bleeding, so packs of gauze are inserted to stem the blood flow.  The packs must be changed daily for the first four or five days and every other day for the next five, requiring patients to face repeated operations in which their wounds are reopened and resewn.

He didn’t even use a special kind of zipper – but a common plastic zipper from the five-and-dime!

Doctor Stone was introduced to this technique during a 1978 medical meeting in Holland.  He watched a Dutch doctor sew a zipper to the tough membrane under the skin.  Conventional surgery to change the gauze pack took an hour or more each time.  Even though the patient still has anesthesia, the surgery is over in five minutes – zip-zip!  Just a dressing is needed to protect the wound and sterilized zipper.  When the pack-changing period is over, the zipper is removed and a permanent suture is substituted.

What color zipper does Doctor Stone use?  He admits that any color will do, but feels that he ought to have proper hospital white.

This makes me thankful for The Great Physician!  He is not invasive but helps us heal wholly and completely – mind, body, spirit! 

NO RE-OPERATION

Once The Great Physician performs surgery, there’s never a need for a re-operation.  🙂

MOLE DAY

TL 10-23 MOLE DAY

If you are not a science nerd or chemistry geek you may not have a clue what Mole Day is – I admit I did not.  Let’s learn together.

Most Americans – 84% – saw science as a positive force in society.  Yet…  all age-groups had a rather flimsy grasp of simple scientific concepts, even those taught in most public high schools, such as gravity or the structure of the atom.  – Priyamvada Natarajan, PhD

MOLE DAY is celebrated annually on this day from 6:02 a.m. to 6:02 p.m. and commemorates Avogadro’s Number (6.02 x 1023), which is a basic measuring unit in chemistry.  That’s about when I started dozing off – but stay with me.  Mole Day was created as a way to foster interest in chemistry.  Various activities related to chemistry and/or moles will abound today.

For a given molecule, one mole is a mass (in grams) whose number is equal to the molar mass of the molecule.  Am I the only one getting a headache?  LOL!  For example, the water molecule has a molar mass of 18, therefore one mole of water weighs 18 grams.  In general, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance.  This relationship was first discovered by Amadeo Avogadro (1776-1858).  He didn’t receive credit until after his death.

Wow – I think the left side of my brain is asleep or something.  So – let’s see how people with a left brain celebrate this Mole O’Ween:

 Auld Daddy Darkness creeps frae his hole,
Black as a blackamoor, blin’ as a mole….
– James Ferguson

Yes – my mind is going toward the animal mole…  guilty!

Well – there’s an idea for your Halloween costume!  You can be Dr. Geek.  Works for me – hmm – not sure about those goggles – they might have to go.

 There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.  – Mark Twain, Life on the Mississippi, 1883

I took science in high school and had to memorize a lot of minerals and stuff – but could not tell you any of them now.  I did what I had to do to pass the course and did not make an A.  I’m sure this is a great day for the smart science geeks  in America and around the world.  Have a good time and Happy Mole O’Ween!  🙂
