Ear Infections
A new study finds that air pollution appears to increase the rate of frequent ear infections in children. The study of 126,060 children found that ears with high levels of sulfur dioxide, the rate of chronic ear infections (3 or more in a year)increased from 6.6% to 8%. They theorize that pollutants may increase the likelihood of infections by increasing mucus levels in the ear.
A Link to Premature Birth
A new study presented at the annual meeting of the Society for Maternal-Fetal Medicine in Chicago found infection fighting genes may be linked to premature birth. In one out of every three premature births, the mother has an infection in her uterus but no symptoms. The genes that fight infection may also cause fetal rejection, but may help more than they hurt overall.
