Answer to Medical Challenge-Yellow Nail Syndrome



Yesterday's Medical Challenge answer was clear to some readers and a mystery to others.  The answer was:
#4  Yellow Nail Syndrome.  Although nails can become discolored from nail polish, the medical Yellow Nail Syndrome is a sign of a serious disorder and not well understood.  It is believed to be associated with  restrictive lung disease or  (rarely) problems with lymphatic drainage channels. (good memory, Grady Doc!)



nail fungus-onchomycosis
Because these nails stop growing and become thicker, they are susceptible to fungal infections too.  Those who guessed Onchomycosis were not far off.   Onchomycosis is very common and the fungus infection causes lifting of the nail from the nail bed.



Psoriatic nail
Psoriasis of the nail can also cause changes that can be confused with Yellow Nail Syndrome.   Ninety-five% of these patients have cutaneous psoriasis also.

Thanks for your diagnosis in this challenging case!

Yea, I got it right!
Wow, that was a tough one! I love these medical challenges. I usually get it wrong, which means I learn something new every time!
Well, You will still need to determine whether it is a fungal infection that is causing your toenails to turn yellow.If you have diabetes, you should see your doctor at the first sign of toenail fungus.

From what I've read on Zetaclear's review, 50% of discoloration of toenails is most of the time a symptom of an impending infection and is usually caused by fungi.

scintillating scotoma

Nothing like experiencing a medical condition first-hand to really help a doctor understand it from the patient's point of view.  After all these years, I had my first (and hopefully last) scintillating scotoma while sitting on the couch playing "words with friends" on my ipad and watching TV.  A scotoma is a partial loss of vision in a normal visual field.  Scintillate is flashing, sparkles.  Put them together and you have moving, flashing sparkles with a blind spot in your eyes.

This visual aura was first described in the 19th century  by a Dr. Hubert Airy who had migraine headaches.  The visual sparks and flashes are in a zig-zag pattern and they can precede a migraine headache or occur without any pain.   The scotoma affects both eyes and closing one or the other does not make it go away.  Sometimes the term "ocular migraine" or "retinal migraine"  are used to describe this phenomenon but these involve only one eye, not both.  The terms are often …

Do Doctors Make Too Much Money?

An article in theNew York Times says the reason health care costs are so high in the United States is because doctors are paid too much. I saw that and my eyes bugged out. I just came home from a meeting with physicians and hospital administrators and the entire meeting was spent discussing the financial challenges physicians face in keeping their doors open to see patients. The goal of this meeting was to keep health services in that community so patients will have someone to care for them. Not a person in the room would agree that the doctors earn too much.

Physicians paid too much? Lets break that down. A doctor spends a minimum of 11 years in education and training after the age of 18. Many are in training for 15 or more years. They are living on student loans and contributing zero to their family's income until the residency years. At that time they earn less than minimum wage if you factor in the 80-100 hour workweek. When a doctor emerges from training (and believe me…

Why Are Doctor Bills So High?

Who hasn't wondered why doctors need to charge so darn much for an office visit? If you have insurance and bother to look at what the insurance company pays, it is always much lower than the charge. Why does medical care cost so much? Is the doctor gouging? One of the best explanations I have seen is stolen from another blog. I would like to give credit but all I know is the name Dr. Adam. He shows this letter to his patients:

Why are doctors' bills so high?

Over the past few years several patients have asked this question. It is a very good question that needs to be answered in the context of our current health care system.
When I was growing up and went to my family doctor, my parents or I paid around $10 for a typical minor problem visit (in 1966). With inflation, that would be around $62 today (in 2006 dollars) (http://www.westegg.com/inflation). Today Medicare reimburses me approximately $33 to $45 for a similar patient visit. When I was a teenager the overhead costs of…
