WILMINGTON, Mass., Jan. 23 /PRNewswire-FirstCall/ -- According to international guidelines published in the January, 2007 issue of the Journal of the American Academy of Dermatology, Photodynamic Therapy (PDT) has been recommended by a consensus group of physicians as a highly effective first- line treatment for actinic keratoses (AKs). PDT, a combination of light therapy and photosensitive topical solution, is often used to treat AKs, a common skin condition that, if left untreated, can lead to squamous cell carcinoma (skin cancer). According to the recommendations, PDT should be considered as a first-line therapy for treating the pre-cancerous lesions. The Levulan PDT system (Levulan(R) Kerastick(R) together with the BLU-U(R) light source) marketed by DUSA Pharmaceuticals, Inc. (R) (NASDAQ:DUSA) is the only currently available PDT treatment approved by the U.S.

Ryan Metcalfe: Voters' waffling on Big Mac is intolerable

A MAJORITY of the Baseball Writers Association of America made a loud statement, but spoke softly about keeping Mark McGwire out of the Hall of Fame with a paltry 23 percent vote for such a prodigious power hitter.

Clearly the cloud of performance-enhancing drugs caused McGwire to receive the low total for a player ranked seventh on the all-time homer list (583) and credited with reviving interest in baseball with his record-breaking 70 homers in 1998. But most writers who chose not to vote for McGwire hid quietly behind their laptops, afraid to stand behind their convictions, while those in the vocal minority boastfully wrote columns about why they voted for McGwire, even if they thought he had cheated by using steroids.

McGwire supporters thumbed their noses at the ethics of their trade, the HOF voting rules and the foundation of what is right in America.
