I am more than a little surprised by this. Fanconi syndrome, a kidney disease that can cause bone damage [1], has been repeatedly found in the medical literature to be caused by taking expired pills of the antibiotic tetracycline. [2]
That these people completely failed to remember these cases is distressing at best.
(I heard an interview with the author of this story on NPR Morning Edition today, and also scanned this story webpage. The only mention of tetracycline was by a web commenter on the story.)
