By adding up "point" totals assigned to certain risk factors, doctors can arrive at a "tragic number" which can help predict which heart attack patients may be at immediate risk of a stroke.
People with osteoporosis who suffer from painful compression fractures of the spine may find relief thanks to a new minimally invasive technique developed by interventional radiologists.
Adverse drug reactions involving the mouth are less common than those affecting the skin, but they can cause extreme discomfort, and perhaps permanent damage to gums and teeth. The most common oral problems experienced are due to the side effects of prescribed medication. The diagnosis of these reactions require, in some instances, a high index of suspicion as they can mimic other diseases.
In a large epidemiologic study of over 3,000 women, wrinkling and dryness of the skin appeared to be decreased in patients with a history of estrogen use. "The concern with all estrogen therapy is that while it may protect women against cardiovascular disease and help maintain bone density, there are serious side effects that can occur," stated Dr. Phillips.
A series of studies from the Massachusetts General Hospital and the Harvard Medical School document the negative effects of hunger in U.S. children and show a link between participating in the national School Breakfast Program and improved academic performance and psychosocial behavior in children.

In its infancy a year ago, a non-surgical procedure to treat painful fibroid tumors and potentially prevent hysterectomy is now widely available at hospitals throughout the country.
A new stroke prevention therapy that is less invasive than surgery showed comparable results to surgery in the most extensive international survey ever done on the procedure. In other stent research, interventional radiologists were highly successful in treating men with a common, difficult-to-treat problem that causes difficulty urinating.
For many, nails are an important part of their appearance. Short or long, manicured or bitten, nails protect the fingers and toes from injury.
The past two decades have witnessed revolutionary advances in laser research and technology, greatly expanding dermatologic laser applications.

The dermatology clinic is the busiest outpatient specialty clinic in the hospital, treating over 21,000 outpatients a year.
Unwanted body hair concerns both men and women. Regardless of the cause, millions of Americans remove unwanted hair daily, by a variety of temporary hair removal strategies that include shaving, waxing, chemical depilatories and tweezing. Electrolysis provides a permanent, but often tedious and slow alternative solution for hair removal
A UCLA orthopedic surgeon has developed a new technique to treat bone death in human hips that early results suggest may prevent the need for a total hip replacement. Called osteoregeneration, the procedure implants a capsule filled with bone-morphogenetic protein (BMP) that induces the body to grow new bone. Only UCLA offers BMP and the attendant procedure.
Researchers from Johns Hopkins and Finland are showing that fancy mathematical footwork plus detailed magnetic resonance imaging pictures of the brain may add up to a better understanding of the experience of thinking.
Researchers at Mayo Clinic have discovered a family of genes linked to neurological damage in a laboratory model of multiple sclerosis (MS). The discovery of these genes represents a significant step forward in understanding the mechanisms by which immune cells cause damage in MS and potential new strategies for treatment.
1.) Overtreatment of lyme disease is common; lyme disease is not associated with increased heart problems. 2.) Can ethical medicine be practiced under the constraints of managed care? 3.) Iron overload often undiagnosed and more common than previously thought. 4) Treatment for benign thyroid nodules should not include thyroxine treatment.
Tumescent liposuction has been the standard of care for liposuction since 1987. This technique, developed by dermatologists, involves the infiltration of large volumes of diluted local anesthetic and epinephrine prior to the liposuction surgery.
President Clinton stated, "Medical decisions ought to be made by medical doctors," in his State of the Union Address January 27. OSHA's proposed standards conflict with this directive.
A study conducted at The Jackson Laboratory and the University of Connecticut at Storrs suggests that the maternal uterine environment in mice can have an enhancing effect on learning ability in offspring across a broad range of behaviors.
The Pennsylvania site where an innovative SmithKline Beecham process allowed the life-saving drug Tagamet (cimetidine) to become widely available was designated a National Historic Chemical Landmark today by the world's largest scientific society, the American Chemical Society, and Britain's Royal Society of Chemistry.
A study examining U.S. mortality rates has found nearly a three-fold increase in deaths from medication errors over a ten-year period, adding fuel to the growing concern that the nation's quality of health care may be suffering because of the shift to managed care.
Routine performance of an exercise test among symptom-free patients who have had coronary artery bypass surgery can help identify those at risk for premature death and heart attack, Cleveland Clinic physicians reported in a study published in the February 28 issue of The Lancet.

One of the many rapidly expanding disciplines of dermatology, representing two quite different approaches to therapy, but with some areas that overlap and complement each other.
It has been shown in clinical trials that a low fat diet can reduce the development of new precancers called actinic keratoses and nonmelanoma skin cancers. Therefore, one recommendation for patients that are at risk of developing precancerous and cancerous growths is that these individuals should consume a diet containing 20 percent of one's total calories from fat.
Alopecia areata is a poorly understood, unpredictable and capricious medical disorder that affects more than 2.5 million men, women and children in the USA and Canada.
