Balintfy: Oral clefts are birth defects that affect the upper
lip and the roof of the mouth. They occur in about two of every
one-thousand live births.
DeRoo: There are two major infant oral cleft types.
Balintfy: Dr. Lisa DeRoo is a Staff Scientist, in the Epidemiology
Branch at the National Institute of Environmental Health Sciences.
DeRoo: Cleft lip with or without cleft palate, or cleft palate
alone.
Balintfy: The causes of clefts are largely unknown, but a
new study finds that women who binge drink early in their pregnancy
increase the likelihood that their babies will be born with
oral clefts.
DeRoo: These findings reinforce the fact that women should
not drink alcohol during pregnancy; and prenatal exposure to
alcohol, especially excessive amounts at one time, can adversely
affect the fetus and may increase the risk of infant cleft.
Balintfy: Dr. DeRoo explains that an alcohol binge is drinking
five or more drinks in one sitting. She adds that women who
consumed this much alcohol were more than twice as likely than
non-drinkers to have an infant with oral clefts. DeRoo: Furthermore,
women who drank at this level on three or more occasions during
their first trimester were three times as likely to have infants
born with oral clefts.
Balintfy: Oral clefts happen when the tissue that forms the
roof of the mouth and upper lip don't join before birth. The
problem can range from a small notch in the lip to a groove
that runs into the roof of the mouth and nose. Treatment usually
is surgery to close the lip and palate. For more on this study,
