Guidelines for CPR have eliminated the giving of mouth-to-mouth
breaths, partly so people will be more likely to give CPR, and
partly because blood flow slows during the time compressions are
stopped to give breaths. Maybe that wouldn't be a problem, but
most people take longer than just a few seconds — up to 16
seconds in one study — to deliver the breaths. Moreover, added
pressure in the chest from breathing into the airways may impede
the flow of blood making a return trip to the heart.
The question of whether or not cancer survivors should take
vitamin or mineral supplements to prevent recurrence cannot be
answered conclusively, because there have not been any studies in
this area. Until that research is done, we must go by the results
of studies of long-term supplement use and how it correlates with
advanced or fatal cases of cancer. Those findings can't separate
out the pre- and post-diagnosis effects of supplements.
Dry, irritated eyes can be caused by a number of conditions, such
as certain autoimmune diseases, and are a side effect of certain
medications. They are more common in women and older people.
There isn't any one specific test to diagnose dry eyes. Most
ophthalmologists will as a matter of course examine the eyes.
Frequently, though, the eye examination and test results are
secondary in the diagnostic workup, especially if the problem is
mild. Symptoms and the patient's history are often the key pieces
of information in arriving at a diagnosis. The first-line
treatment for most people with dry eyes remains an
over-the-counter topical treatment of some kind, typically drops.
The prescription cyclosporine drops are usually used after
patients have tried the over-the-counter products.
As the immune system weakens with age, the risk of shingles
increases. Shingles starts to become more common in our 50s; half
of everyone who makes it to age 85 will have experienced shingles
some time along the way. But anyone harboring the varicella virus
in their nervous system, which is true of most everyone over age
40, and who has an impaired immune system is vulnerable. Federal
vaccine officials have recommended that everyone age 60 or older
with a healthy immune system be vaccinated against shingles.
My niece has been diagnosed with body dysmorphic disorder. I've
heard of it, but I'm not sure what it is exactly.
