Decalcification of teeth in a microwave oven.
The effects of microwave radiation in reducing decalcification time were evaluated by measuring rates of calcium removal from samples of rat and cat teeth in 0.1 mol l-1 EDTA. In some cases, 3% glutaraldehyde was added to the decalcifying solution. Test specimens were placed in a microwave oven at 39 +/- 2 degrees C for repeated periods of 1-2 h. Control specimens were placed in a conventional oven at 39 degrees C for the same times or held at room temperature. The calcium removed during each treatment was measured using an atomic absorption spectrophotometer. There was no consistent difference between the results obtained with microwave radiation as compared with heating in a conventional oven, although in both cases decalcification was slightly faster than at room temperature. These results are attributed to thermal effects. No evidence for non-thermal effects of micro-radiation was found.

Investigation of healthcare providers' patterns of referring breast cancer patients to Reach to Recovery.
Providers who referred patients to Reach to Recovery (Reach), an American Cancer Society breast cancer support group, were compared with those who did not to evaluate whether providers who identified problems with the program were less likely to make referrals. Also considered were contact with a Reach volunteer, having a Reach program in the area, years since residency or medical training, perceived value of the Reach program, belief that one's peers refer patients to Reach, urban or rural location of practice, and size of practice. When other variables were considered, physicians who identified problems with Reach were no less likely to refer patients to the program than those who did not. The factors most associated with referral (P < .001) were "having a Reach program in the area" and "having had contact with a Reach volunteer." Implications of these findings and the experience of conducting the evaluation through the Collaborative Evaluations Fellows Project are discussed.
