Old Ultrasound is back again

New Doppler sound database could help those suffering from heart conditions

Summary:
Handheld devices can scan the lower limbs of a patient and 'listen' to the blood flow, providing vital early indication of problems that could lead to strokes or heart attacks.  But inexperience or lack of training sometimes mean that clinicians do not properly interpret what they hear and therefore miss the warning signs. Now a new research project aims to build a digital library of the different foot and leg artery sounds recorded during the Doppler ultrasound procedure.

Note:  We have been using the ABI index for over 50+ years.  Happy Easter!

A Tale Of My Travels While Teaching Ultrasound (One of Several Stories)


I have taught medical ultrasound to doctors and medical professionals around the world (see archives).  There are many stories of travel we all like to share when we leave our home country to travel to other countries, and experience other cultures.  I will begin this series by apologizing for my absence.  My wife and child have been plagued by a set of misfortunes which have made me devote most of my time to see to their wellbeing.  All is well at the moment, so I thought I would take a few moments to blog again.

I present one story, of many I want to post of the

sideline stories seasoned travelers may find amusing, and new travelers may find helpful.

Hong Kong Snake Dinner

 Here we have a true tale of a dinner party that was something out of a food TV show with a nice bald twist.  I lost my hair when I was thirty, and have not missed it.  I have only the look of a Friar from a monastery.  Most of my Chinese hosts have a full head of hair, so I guess I was labeled as a popular food critic from the USA.  My Chinese host physicians made a point of taking me and my associate out for sumptuous lunches every day during our three week stays in Hong Kong.  My coworker was female, and lunches were always a great, and very social event with the large table dominated by three pots of hot tea (green, Oolong, and another tea).  The Chinese take great care to pour tea for guests, because they are special.  In the Chinese culture, it is disrespectful to turn away food or drink when served by the host, in this respect it was my Chinese students who chose to respect a teacher, I later found out.

Our lunches were always proper, with white table cloth, Western silver settings, and several dishes.  My associate and I loved these social events because they took over an hour, but we tired of the endless array of dishes served out.  We were ready to get back to teaching these wonderful people how to perform sonograms, and get back to the hotel to get a good night sleep.  Jet lag had a part in this, of course..

One night, a male cohort of physicians enticed me out to join them in an ultimate male bonding ritual: Snake Dinner.  (See the links below)

Note, this offer of dinner was not extended to my female associate for cultural reasons.  I cannot explain that.  She graciously declined.  I was picked up by a pack of wonderful medical doctors, and off we went.

So, here we go out  walk like usual to a restaurant for supper, rather than lunch. I Love
 to walk, and I am amazed at how fit the Chinese people are.  Most walk if possible to work, or for meals.  The streets are full of the usual honking, and hordes of people, but all was very orderly, and my attention quickly turned to olfactory rather than dodging pedestrians.  Hong Kong is a city of smells.  You understand this when you get off the M-subway for the first time.  It Is Smell!  the melange can overwhelm a western person.


After many blocks through Kowloon, we are ushered into a small restaurant and seated at a large table, and immediately served with bottles of rice liquor.  My host party set upon me like a pack, and attempt to make me drunk by refilling my small cup multiple times with a hellish rice moonshine.  I learned quickly not to down the drink.  It was apparent that to do so would spark a rush of eager hosts willing to refill my small cup with more brimstone.

Then the Snake Man made his entrance with his eyes  on me.  I was the only Gadjin in the
party of twelve.

approached the table with a cart of hissing serpents.  He held my gaze and asked which snake?  He said they are all poisonous cobras. He seemed miffed that I would ask such a stupid question.

He took the snake from the cage, and used a green scalpel to gut it from appetite
