Best Medication for Dizziness

So how would one go about figuring out the best medication for dizziness due to motion-sickness leading to nausea and even vomiting?

Well, step 1... Put a bunch of people in a machine and figure out the necessary motions that will cause dizziness.

Step 2... Do the same thing, but this time, put people on different medications and figure out what works the best.

Sound crazy?

Well it has been done by the friendly folks at NASA. Why would they perform such unpleasant experiments? It's for the fighter pilots and astronauts who may encounter motion sickness where dizziness may mean the difference between life and death and have no alternative other than medications.

So what medication did they find works the best?

Through trial and error, they have found that a combination of oral scopolamine (not the patch), to suppress vomiting, and dextroamphetamine, to counteract scopolamine's potential to induce drowsiness, reduced the incidence of motion sickness from 70 percent to about 12 percent among passengers in the "Vomit Comet"—a DC-9 aircraft used to achieve brief periods of zero gravity as part of NASA's Reduced Gravity Program.

They have also found that conditioning (repeating movements that induce dizziness) over and over again does result in the development of tolerance to a motion environment in 95% of individuals.

Should You Have Surgery Far From Home???

I am in the fortunate position of seeing patients who live locally as well as a handful who travel across one or more state lines to see me on a weekly basis, as well as the sporadic few who come from even other countries.

When patients travel great distances to see a doctor, this puts the physician in a particularly humbling position. However, it also places additional strain on how care can be provided efficiently and reasonably when geography logistically makes it difficult.

To begin, why would a patient even want to travel great distances to see a doctor? The basic answer is due to the perception that they would receive better care than can be obtained locally. If true, such long distance travel is justified. After all, if you have thyroid cancer and there are no surgeons who can remove this cancer, than by all means, travel is merited.

However, too often, I see patients travel great distances to see a surgeon due to the perception that this one particular doctor is better than the one found locally, EVEN if the local surgeon is quite competent. Here is where the decision to travel becomes... well... less logical, especially if the surgery is for a routine problem.

IF there's a local competent surgeon, I feel it is ALWAYS better to get the surgery done locally. Why? Because if there's any problems after the surgery, it can be easily addressed quickly and with minimal fuss. If the surgery was done hours away, think of the travel, expense, missed time from work, etc NOT just for the surgery, but for any post-operative problems that develop. Oftentimes, the patient concern ends up being unfounded and only reassurance is required, but in order to make that determination, the surgeon needs to do an exam. Imagine the frustration of the patient when a surgeon requests a visit before answering a question about a post-surgical concern... hours of driving to the office, waiting in the exam room, being seen by the surgeon for a few minutes only to hear that everything is fine and normal, and finally driving hours back home.

Even in the hands of the BEST surgeon, problems can arise after surgery. Is the surgical wound becoming infected? Where is that fever coming from? There's a little drainage occurring... is that normal? Why is the skin red? There's a lot of pain and his medications aren't working.

To complicate things further, narcotic pain killers can NOT be called in by federal rules. A hardcopy prescription is required. Now, wouldn't that be mighty inconvenient if a patient (who mind you is in pain), needs to drive hours to the surgeon's office just to pick up a hardcopy narcotic prescription.

The logistical difficulties of dealing with post-operative care after patient discharge is tremendous for both the surgeon as well as the patient if the distance between the two is large.

Now when should a patient travel to have their surgery done?

DO travel to see a surgeon when your local surgeon feels it imperative that you do so either due to the complexity of the problem or inexperience. Especially, if the local surgeon is well-respected and honest. This serves two purposes... you get the surgery done by the best possible... AND, if any problems develop after surgery, your local surgeon is in the loop and can probably handle most routine post-surgical concerns.

I should state that I HAVE performed surgery in patients who live hours away (some even an airflight away) but I ALWAYS encourage patients to try and get the surgery done locally if at all possible due to the reasons stated above. If a competent local surgeon is not available, than that's fine. But if competent local surgeons are present... I do my best to steer patients to get the surgery done locally as it IS for the patient's best interest.

I have also referred patients to other surgeons a long drive away due to one reason or another, even if the patient desperately wants me to do the surgery. I'll be the first to admit if I lack experience to address a given problem. I also follow-up in stating to the patient that if there's any problems that occur after the surgery, to please return to see me rather than making a long-distance trip as there's a good chance I'll be able to address the concern. Everyone wins this way.

Pediatric ENT Care of Warrenton, Virginia (Fauquier County)

Recently, there has been some confusion regarding whether our office deals with adults only or do we see kids as well... Strangely enough, we also get asked by parents whether our office sees adults when seeing a pediatric patient.

To clear up any confusion, our office does see kids AND adults... starting from birth to the elderly.

Dr. Chang who joined the office in October 2005, was named one of America's Top Physicians by the Consumer's Research Council of America in 2008 as well as a Northern Virginia Top Doctor for 2011 (to be published in February 2011).

Some common problems and procedures for which Dr. Chang sees kids specifically include:

- Tongue Tie Release (starting from ONE DAY OLD!)
- Tonsillectomy
- Adenoidectomy
- Sinus Surgery starting with adolescents
- Ear Tube placement
- Hearing Loss
- Nasal Obstruction
- Nasal Congestion
- Snotty Nose
- Speech Delay
AND many other issues...

Our office has even created videos on a few common pediatric procedures including tonsillectomy, adenoidectomy, earwax removal, ear tubes placement. Watch the video below on tonsillectomy.

The Perfect Computer for Healthcare and Electronic Medical Records

So I've been using computers in the healthcare setting for over a decade now. First at Yale than Duke. I've been thru the Veteran's Affairs Medical Center using Vista (New Haven, CT; Durham, NC; Asheville, NC; and Portland, OR). I've been at 5 different community hospitals on both the West and East Coasts. I've used all the different flavors of electronic medical records (EMR) in all these different locations/settings. I'm now using (not by choice) NextGen, Meditech, Rcopia, and PACS currently in the office, hospital operating suites, and inpatient settings.

Throughout this time period, I've used desktop computers, handhelds, laptops, netbooks, and tablet computers. I've even tried to cobble together a semi-functional iPad able to access all the different EMRs I need on a daily basis (read blog about this here).

What I discovered is that the perfect system (in my mind) is ALMOST there... just not quite yet. Maybe in the next few years, it will exist because all the pieces now exist! The bad news is that it does not exist RIGHT now.

So, here's my dream machine and the reasons. I hope some computer company is paying attention!

To understand how this all fits together, one needs to envision how my office works right now. There's a desktop computer in each exam room. Patients are taken back by a nurse and information inputted into the desktop computer. Than the computer is locked and the nurse leaves. The physician than soon follows, unlocks the computer, and then proceeds with further history, exam, and plans treatment which all gets documented in the computer. If tests are ordered (ie, hearing test, blood draw), the doctor leaves and sees another patient while the tests gets done before coming back. As such, the computer stays in the room with the patient. One can envision that there is a lot of back and forth into and out of an exam room movement of nurse, doctor, and patient. The computer gets locked every single time. Furthermore, I need EMR access when seeing patients in the hospital as well as during surgery.

First the Hardware:
• A tablet touchscreen (with no physical keyboard) 12 inches diagonal. That size hits the sweet spot. Any larger and the size itself becomes unwieldy to constantly move around as well as heavy by the end of a day. Any smaller and the screen real estate becomes so small to become inefficient. 12 inches diagonal also allows the possibility of an actual full-size virtual keyboard on the screen with adequate screen left-over to see what's going on.

My experiences with the iPad virtual keyboard was mixed (given it is somewhat smaller than full-size). I CAN do it and I did do it... I just didn't like it to the point I relied on a wireless bluetooth keyboard.

• Bluetooth technology and WiFi are a MUST because...

• With this tablet computer, one can dock it without wires or connector pins (similar in concept to Motion Computing JR3400 with its FlexDock). The docking station allows for use of regular USB keyboards and mouse along with direct ethernet wired connectivity. My dream machine docking station and tablet would communicate with each other using bluetooth or some other alternative short-range wireless technology which makes direct physical connection unnecessary. This is important, because I would have the docking station in each exam room. When I leave the exam room, I would have the option of taking the tablet (and therefore the screen) with me. The constant connecting and disconnecting of current docks is quite the pain given it requires an actual physical connecting port as well as precise placement. With the constant connecting and disconnecting, it opens the possibility for breaking as well.

What would be even cooler would be if the tablet charges when in its docking station using inductive charging similar to how a Philips Sonicare Toothbrush recharges.

Why do I even want a docking station? Several-fold. Ergonomics... I like the screen at my eye level. Also, I can still see the patient while typing away. If I depended on the virtual keyboard like on the iPad, I'm looking down which is not patient-friendly as well as a pain in the neck (from looking down). Also, though I guess I can learn to type fast on a virtual keyboard, I think I would still prefer the physical full-sized keyboard if given a choice. Furthermore, though wireless WiFi for all internet connectivity is nice in principal, it does introduce potential security problems as well as speed issues (wired ethernet in my experience is still the most reliable and fastest way of communication along with being secure).

However, WiFi connectivity is still important as pretty much every medical setting has WiFi and so one does have continuous high speed wireless access. Also, it would allow me to read a little bit of what's going on with a patient before walking into an exam room (I would load up the patient's chart using the touchscreen before walking into the exam room and docking the tablet). I just do not want to always DEPEND on WiFi.

A WiFi tablet touchscreen like the iPad is also great as one can BRING your office with you where-ever you go like the hospital and operating room without bringing a keyboard, mouse, etc. It's all self-contained. It's intuitive. It's all neatly packed into a simple, elegant tablet touchscreen that's highly portable and usable.

• Proximity security whereby the computer tablet "knows" you are right there. When you are no longer around the computer, it automatically locks. When you come back, it recognizes you and it automatically unlocks, all occurring invisibly to me without requiring me to actually do anything. I HATE the fact that I have 4 different userids with 4 different passwords to access the various EMR programs. Though I try to, I do not always remember to lock the computer 100% of the time. It should be all automatic. Does the technology exist? It sure does... It's called Single Sign-On for one userid and password that unlocks it all. And Xyloc by Ensure Technologies to allow for proximity recognition using RF technology. All I ask is that this technology be built-in to the hardware!

In a clinic where I'm constantly moving around where the tablet may not always be with me, due to HIPAA and HITECH, the computer needs to be secured. Though I try, I can not always remember 100% of the time to lock the computer. And same goes for my medical assistants. The security should be automatic, invisible, and secure.

The problem with biometric verification like fingerprint scanning or even ID card swipes is that I have to REMEMBER to do it. And the mere fact of doing it is aggravating because I would have to do it SO many times in a given day.

• Sturdy construction. The tablet is going to move around... a lot... It needs to stay working after being dropped from at least a height of 3 feet.

Which Brings Me to the Software:
What can I say? I LOVE the intuitive and simple interface of the iPad. Now, there's a few things I would tweak about it to make it MORE relevant in the healthcare setting.

• Multi-Tasking is a must. As I literally use Meditech (hospital EMR), NextGen (clinic EMR), Rcopia (electronic prescribing software), and PACS (radiology viewing software) all day long swapping back and forth even with a single patient encounter, I need to be able to easily jump between all these programs without shutting down the others. From what I understand, this functionality on the iPad will soon be reality with the release of the iOS4 operating system later June 2010.

• I constantly move back and forth among Meditech, NextGen, Rcopia, and PACS all day long. As such, having a few physical programmable buttons on one side of the screen on the edge would be wonderful which I could just press and it would take me immediately to my program of choice. Keyboard shortcut works, but imagine what touch-strokes would be required when I'm using it in pure tablet touchscreen mode...

• Apps already exist to connect via Citrix, Remote Desktop Connection, or screen mirroring... so I would just use those programs. If I was prone to unrealistic wishful thinking, I would ask for a single EMR program that incorporates Meditech, Nextgen, Rcopia, and PACS, but I do not forsee anything like that happening for decades (if ever). So, I'm going to stick with what is possible.

• A "tablet pen" is 100% optional and not necessary for use... Tablet touchscreen would be used predominantly using a finger(s) just like on the iPad. Personally, I do not foresee myself ever using a tablet pen. It's just one more thing that can get lost.

That's pretty much it! Is that so much to ask for???
