VIOLENCE UP IN INNER-CITIES:

Violence in inner-cities is turning trauma centers across the nation into
madhouses. Dr. John Barrett, Cook County Hospital, Chicago, presented a study
showing drugs and guns were the sparks igniting the flame. In one year, 714
shooting victims were treated at his hospital; 20 percent had multiple gunshot
wounds, up from 5 percent a decade ago. (From the USA TODAY Life section.)

ELECTROMAGNETIC FIELD DANGERS:

According to a government study, evidence is growing that low-frequency
electromagnetic fields generated by all electronic devices - including house
lights, toaster, stove and power lines - effect changes in cells. These fields
may increase your risk of ills ranging from neurological disorders to cancer.
The Office of Technology Assessment is conducting
research in this area.

ELECTRIC BLANKET DANGERS:

Sleeping under an electric blanket exposes you to stronger electromagnetic
fields than does living under most types of high-power transmission lines,
scientists say. Researchers at the University of Colorado in Denver found
expectant mothers who used electric blankets had a higher miscarriage rate
than non-users; babies grew slower in the womb of electric blanket using moms.

EXERCISE HELPS ARTHRITIS:

The number of younger arthritis victims is increasing, with twice as many
female as male. Dr. Robert Ike of the Rheumatology Division of the University
of Michigan Medical Center says exercise is important in treating arthritis
and, contrary to what was once believed, many people can exercise without
further damaging joints. Work with a doctor to find an individualized routine.

MODEL MIMICS HEART ARRHYTHMIAS:

A computer model has been developed that simulates disruptions of the
electrical signals that cause normal heart rhythms. The model has given
researchers new insights into the way the heart muscle cells are electrically
coordinated to contract. Currently it is being used to study the role that
damaged heart tissue plays in generating ventricular arrhythmias.

CALCIUM IMPLANT HELPS HEALING:

Paul Ducheyne, a bioengineer at the University of Pennsylvania, has
developed a new method of reconnecting shattered bones. The method uses
ceramic material applied directly to the broken bone fragments, which allows
them to heal more quickly. The experimental technique, currently being tested
in hip joint replacements, may eliminate the need for steel pins.

ARTHRITIS CAUSED BY HORMONE:

Rheumatoid arthritis may be the result of a flaw in the brain's regulation
of a hormone released in response to physical or psychological stress, rather
than from a defect in joints, according to researchers at NIH. Animal studies
have given science an advance in the relationship of the nervous system and
health.

FLUORIDE'S ROLE IS LIMITED:

A study in the New England Journal of Medicine indicates that sodium
fluoride increases bone mass but can result in a greater susceptibility to
bone fractures when used as a treatment for osteoporosis. The National
Osteoporosis Foundation says results confirm that sodium fluoride cannot be
considered effective treatment for the bone-thinning disease.

STUDY ON SODIUM FLUORIDE:

A study on sodium fluoride as treatment for osteoporosis was conducted by
B. Lawrence Riggs, M.D., Mayo Clinic and Foundation. Results: Patients
treated with sodium fluoride showed a 35 percent increase in spinal, or
vertebral, bone mass, and an insignificant reduction in vertebral fractures.
Only established drugs, like estrogen replacement and calcitonin are
recommended.
