scientific evidence

There’s something about autism that invites scapegoating. The latest attack was on makers of Lexapro, the anti-depressant medication, when used during pregnancy. Six plaintiffs recruited three experts to testify to a supposed causal connection between the drug and their children’s affliction. The court rejected the expert testimony outright and dismissed the case. Three weeks ago, the Second Circuit affirmed. The decisions, while applaudable, are problematic.
In December, a federal judge dismissed 50,000 Zantac cases because the scientific evidence establishing cancer causation didn’t pass legal muster. In March, a California state judge reached the opposite conclusion. What happens next?
A series of class action cases claim that Zantac can cause cancer. It is not Zantac per se, but a degradation-produced, N-nitrosodimethylamine (NDMA), which may cause cancer at high doses. What do we know about NDMA?
Acid indigestion. Just the words give me heartburn. Multiple remedies are available, both prescription and over-the-counter. But hundreds of thousands of people are claiming that they got cancer from one of them: Zantac. Their cases are pending in various courts around the country. The decision regarding the admissibility of their expert testimony in federal cases was just released. So, how did the plaintiffs fare?
