A calcium-to-zinc imbalance, yeast, dysbiosis, low zinc, heavy metal toxicity and abnormally high levels of aluminum, antimony, arsenic, cadmium, copper, lead, nickel, silver, tin, titanium and selenium.  You name it, and Dr. Anjum Usman diagnosed it regarding a child with autism

The treatments he used include dietary restrictions; nearly three dozen vitamin, enzyme, mineral and other dietary supplements; two antifungal drugs; four chelators or detoxifying drugs; a hormone suppressor, and hyperbaric oxygen treatments, in which the child is shut inside a pressurized bag filled with extra oxygen.

'Alternative treatments' that turn out to be uncontrolled experimentation on children? What a shock.

Usman was prominent in the Defeat Autism Now! movement, which has promoted many risky and unproven therapies.  The the Illinois Department of Financial and Professional Regulation may finally have had enough and is asking that her medical license be revoked.
