Speaking of the ethical problems with attorney-driven lung screenings, the WSJ had a (subscriber-only) editorial on the subject yesterday. Relevant excerpt:

a coalition of industry and other groups has began pushing the National Institute for Occupational Safety and Health (Niosh) to start policing its "B-reader" program, which certifies doctors to read X-rays. The federal agency proposed new ethics rules in November, after a federal judge slammed several government-certified doctors who had ginned up sham diagnoses in a silicosis suit. But Niosh needs to go much further to clean up this corrupt corner of American medicine.
