I do so love to report these wins for reality, as rare as they are: the very vocal antivax advocate Mark Geier has had his medical license revoked in Maryland. Why?

The Maryland State Board of Physicians reviewed nine cases of autistic children seen by Geier, of which he treated seven. Of those nine, the Board found he misdiagnosed six of them. He (mis)diagnosed them with "precocious puberty", a medical condition where kids have extremely early onset of puberty. Why would he do such a thing?

Geier happens to think Lupron can also help autism — despite there being no evidence at all that’s the case — which makes his diagnosis very suspect. It implies strongly that he used the precocious puberty diagnosis as an excuse to prescribe the drug.

By the way, Lupron costs $5000 – $6000 a month to administer. The side effects can be severe as well, including seizures, and it’s known that autistic children are prone to seizures. That’s why the Board wrote that Geier’s treatment "exposed the children to needless risk ...
