Our results demonstrate that prior to the educational intervention, many patients with early breast cancer were undergoing inappropriate radiological staging. Since 2003 however, for Stage I patients there has been a significant improvement in adherence with the guidelines. We hypothesize that our educational intervention had a positive impact on improving the utilization of baseline radiological staging in patients with primary breast cancer.

Physical and chemical investigations of microscopic spherules from three recently or currently active volcanoes show them to have the same general abundances and composition as we previously found for deposits from extinct volcanoes. These results support our conclusion that a volcanic origin is unlikely for the majority of the spherules recovered in arctic ice deposits and other remote sites.
