Occupational Risk Reducible
(Continued from page 1)
National studies have shown
gamma globulin treatment to be
effective in preventing it, Hamilton
added.
Don't Wait
“I'd like to stress that no one who
may have been exposed should put
off going to Employee Health," he
said. "While the chance of
contracting hepatitis B from such an
exposure is only about 20-25 per cent
without treatment, it is not like
catching a cold.
"It is much more serious than that,
and gamma globulin treatment can
substantially reduce the risk."
A vaccine now being developed
may eventually be used to immunize
health care j>ersonnel who might be
exposed to the disease, but its
licensing by the Federal Drug
Admiifistration is still years away.
Hamilton also pointed out that
physicians often tend to be more
concerned about the health of their
patients than with their owm health.
With regard to hepatitis B, such an
attitude is "short-sighted," he said,
because as a group, physicians have
the highest risk of contracting it.
Technicians handling patient
specimens in outlying research
laboratories also should be aware of
the potential hazard and follow the
same procedure as everyone else if
they think they may have been
exposed, Osterhout added.
Follow Precautions
The best way to avoid hepatitis B
}S by following simple and
long-established precautions.
Hamilton said they include:
—using great caution in disposing
used needles in the proper
receptacles located in each patient
care %rea. Environmental service
workers are sometimes stuck by
needles thrown carelessly in the
trash.
— paying attention to signs on
patient doors and to patient name
bands. Yellow name bands and the
sign "Blood Precautions" indicate
that a patient is capable of
transmitting hepatitis.
—being careful when transporting
specimens, especially blood
products, but also sputum, stools
and any others.
— avoiding the use of mouth
pipettes during blood work.
— and again, reporting to the
Employee Health substation when
there has been a breach in technique
and a possible exposure.

BEGINNING OF THE END—Bruce Wright recreates the pomt at which it became
apparent that Duke's computer chess program would defeat the Soviet Union's. The
Russians conceded the game, something Wright says is seldom done in computer
chess. The outcome of the game might be reversed if a computer malfunctions or
hits a programming error, he said. (Photo by Ina Fried)
Russians Bow to Duchess
Bruce Wright, senior computer
programmer, with the cardiovascular
computer laboratory in the medical
center, has helped to beat the
Russians.
He is a member of the Duke chess
team whose computer program.
Duchess, defeated Kassai, the Soviet
Uriion's defending international
champion, in the International
Cibmpufer Chess Tournament in
Toronto, Canada, in August.
Northwestern University won the
tournament, however, with a 4-0
record. Duchess and Kassai tied for
second with 3-1 records.
This was the first time Duke had
entered a program in international
competition but the team previously
placed fifth in the national
tournament, earning the right to
perform at Toronto.
The team that wrote Duchess
started developing computer chess
programs seven years ago. Working
with Wright were Eric Jensen, a
former Duke undergraduate now a
programmer for a computer firm in
New Jersey, and Tom Truscott, a
graduate student in computer
science. •
Advisers were Alan Biermann,
assistant professor of computer
science, and Dr. Dietolf Ramm,
associate medical research professor
in the Center for the Study of Aging
and Human Development and
assistant professor of computer
science.
Wright said he had played chess
for a number of years and that he
became interested in computer chess
while taking an undergraduate
course in computer science here.
After each tournament, he said,
program modifications are made to
give the program more game
possibilities to consider more
quickly.
The program was developed using
a computer at the Triangle
Universities Computation Center in
Research Triangle Park. During the
tournament in Toronto, the team was
linked to the computer by telephone
lines.
Wright worked part-time in the
medical center while a student at
Duke and has worked full-time here
for about two years.
