The Five Phases Of Medicine

In many respects, medicine has come a really long way, and yet in other ways it seems like it still has so far to go. 

For example, while antibiotics are used to routinely treat many bacterial infections, there are few antiviral treatments currently available--and we are left with the proverbial, "take two aspirin and call me in the morning."

Similarly, heart attacks, strokes, cancers and so many other ailments still take their victims and leave the bereaving family asking why?

In thinking about medicine, there are five major historical phases:

1. Do nothing: Get hurt or ill, and you're as good as dead. You shudder at the words "There is nothing we can do for you." Average lifespan for folks, 30s.  If you're lucky (or wealthy), you may make it into your 40s or even reach 50. 

2. Cut it: Diseased or damaged limb or body part, chop it off or cut it out surgically.  I still remember when the people in my grandparents generation called doctors, butchers. 

3. Replace it: When something is kaput, you replace it--using regenerative medicine, such as stem cell therapy (e.g. for bone marrow transplants or even for growing new tissue for teeth) and bioprinters (like a 3-D printer) to make new ones. 

4. Heal it: Envision a future with self-healing microbes (based on nanotechnology) in the blood and tissues that detect when a body part is dangerously ill and deploys repair drones to fix them.  There is no need to cut it off or replace it, you just fix it. And perhaps with DNA "profiling"(don't like that word), we'll be able to tell what a person is predisposed to and provide proactive treatments. 

5. Eliminate it: Ok, this is way out there, but could there come a time, when with technology (and of course, G-d's guiding hand) that we can eradicate most disease. Yes, hard to imagine, and with diseases that adapt and morph into other strains, it would be hard to do--but that doesn't mean it's impossible. 

I still am shocked in the 21st century with all the medical advances and technology that we have that the doctors still say for everything from routine colds, to viruses, sores, growths, and more--"Oh, there's nothing we can do for that." 

Yet, there is what to look forward to for future generations in terms of better medicine and perhaps with longer and better quality of life.

My grandfather used to say, "No one gets old without suffering"--let's hope and pray for less and less suffering with future medical technology advances. ;-)

Seeing Is Believing

This robotic seeing eye dog from Japanese company NSK is an incredible display of how technology can help the blind and was profiled in PopSci on 9 November 2011.

While there are reports of many advances in returning sight to the blind through such breakthroughs as stem cell molecular regeneration and camera-like retinal implants, there will unfortunately be medical cases that cannot be readily cured and herein lies the promise for robotic guide dogs.

These dogs do not provide the same companionship that perhaps real dogs do, but they also don't require the same care and feeding that can be taxing, especially, I would imagine, on someone with a handicap.

The Robotic Seeing Eye Dog can roll on flat surfaces and can climb stairs or over other obstacles.

It is activated by a person holding and putting pressure on it's "collar" handle bar.

The robotic dog can also speak alerting its handler to specific environmental conditions and potential obstacles, obviously better than through a traditional dog bark.

The dog is outfitted with Microsoft Kinect technology for sensing and navigating the world.

It is amazing to me how gaming technology here ends up helping the blind. But every technological advance has the potential to spur unintended uses and benefits in other areas of our life.

Recently, I saw an advertisement for MetLife insurance that proclaimed "for the ifs in life" and given all the uncertainties that can happen to us at virtually anytime, I feel grateful to G-d for the innovation and technology that he bestows on people for helping us handle these; sometimes the advances are direct like with Apple's laser-like focus on user-centric design for numerous commercial technologies, and other times these are more indirect like with the Kinect being used for helping the blind, or even the Internet itself once developed by the military's DARPA.

I imagine the technology cures and advances that we achieve are almost like a race against the clock, where people come up with counters to the ifs and threats out there, adapting and adopting from the latest and greatest technology advances available.

Advances such as Kinect and then taking us to the robotic seeing eye dog, bring us a little closer--step by step, each time incrementally--to handling the next challenge that calls.

This week, I was reminded again, with the massive asteroid YU55 speeding past us at 29,000 mph and within only 202,000 mile of a potential Earth collision (within the Moon's orbit!), how there are many more ifs to come and I wonder will we be ready, can we really, and whether through direct or indirect discoveries to handle these.
