Alleged Medicare cheat loses paper for data mix-up

A Boston doctor indicted on charges of Medicare fraud in 2007 has had a paper relating to the case retracted this month.

Abdul Razzaque Ahmed was considered something of a miracle worker by his patients, treating two rare and disfiguring skin conditions called pemphigoid and pemphigus vulgaris. He used more powerful medicines than the typical course of treatment, including a drug normally used to treat cancer.

The initial indictment stated that Ahmed mixed blood samples to falsely show a “dual diagnosis” of both diseases, and prove to Medicare that they required the more rigorous (and expensive) treatment. It also alleged that he profited massively from the government pay-outs. He was convicted of obstruction in 2007; the other charges were dropped when he agreed to forfeit assets worth $2.9 million.

Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed. Here is the retraction notice from Clinical Immunology: Continue reading Alleged Medicare cheat loses paper for data mix-up

Fraud topples second neuroscience word processing paper

neuroimageWe have a second retraction from a group of neuroscience researchers in Belgium who discovered fatal errors in their work on how the brain sets about the task of reading written language. Spoiler alert: Turns out those errors weren’t errors after all.

As we reported back in May, the group, from the University of Leuven, was unable to replicate certain fMRI findings in a November 2012 article in Neuroscience. At the time, Hans P. Op de Beeck, who led the group, told us: Continue reading Fraud topples second neuroscience word processing paper
