Periodontitis and CVD: What Is the Link? - Medscape, 3/18/05 - "An association between periodontal health and systemic disease is not farfetched in light of research confirming that Escherichia coli and Helicobacter pylori (among other organisms) have also been linked to atherosclerosis and cardiovascular events.[5] In perhaps the same manner, periodontitis disturbs systemic homeostasis. It is possible that chronic damage of epithelial tissues due to periodontitis may induce the periodontal pocket to ulcerate, allowing access to the bloodstream.[4] Bacteria and their toxins, localized tissue response to cytokines (proteins that regulate other cells in the blood), and additional mediators of inflammation can all disrupt homeostasis when toxins gain entry to the systemic circulation"

Analysis Shows Drug Could Save Lives From Prostate Cancer - Science Daily, 3/16/05 - "the commonly used drug finasteride reduced the incidence of prostate cancer by 24.8 percent compared to a placebo.

No difference in mortality was seen during the 7 years of PCPT" - See finasteride at OffshoreRx1.com.
