...would exposure to influenza during pregnancy increase the risk of schizophrenia? No one knows. Perhaps the infection somehow damages the developing brain. Or the reason may have something to do with how influenza affects the mother's lungs, decreasing the amount of oxygen that can get to the fetus. But even if the link is real, it would account for just 14% of schizophrenia cases...
...Plasmodium falciparum, which has a particular fondness for anopheles mosquitoes. The parasites enter the bloodstream when an infected mosquito bites a human. Then they multiply inside the host's liver and red blood cells. (That's why pregnant women, who make lots of blood to nourish their growing fetus, are especially vulnerable.) Eventually the red blood cells burst with a new generation of parasites, causing fever, shivering, pain and sometimes death. The cycle of transmission is complete when another mosquito bites an infected person and picks up more parasites...
HEALTH: Is taking sonographic snapshots of your fetus safe...
...just too long. Not willing to wait for the birth of their child and the accompanying flash photos, parents-to-be are shelling out $200 and more to ultrasound centers with cutesy names like Prenatal Peek and Womb with a View for high-res, golden-hued ultrasound images of fetuses in their amniotic homes. It's not hard to see the appeal. The latest advances in ultrasound technology--from grainy 2D to glorious 4D with accompanying DVD--produce images that are impressive, showing facial features, hair, fingers, toes and even a fetus' sex. Some companies throw in a sound track...
...there may be risks. The FDA issued a firm warning earlier this year in its consumer magazine. Although there are no reported cases of ultrasound causing harm to a fetus, the FDA SAYS we simply don't know enough about the long-term effects of repeatedly sending high doses of energy across a mother's womb. After all, these ultrasonic waves are the same as those used at higher exposure to break up kidney stones. Laboratory studies have shown that even at low levels, ultrasounds can produce physical effects in tissue, including jarring vibrations and temperature increases. John Hayes, editor...
