Another way to mess up a fetus: take the wrong antibiotics

What a difference in headlines.

• In the LA Times, it's "Most antibiotics appear safe during pregnancy, study finds". 
• As the AP sent  it out, it was headed "Study ties common antibiotics with birth defects".
• Science Daily said, "Antibiotic Use During Pregnancy And Birth Defects: Study Examines Associations"

The study said that a number of common antibiotics are safe, most especially the most common, penicillin, but sulfa drugs and nitrofurantoins might cause some bad birth defects.
