Approaches towards the public-health prevention of bioterrorism are too little, and too late. New information-based approaches could yield better homeland protection. An internet civil defence is presented where millions of eyes could help to identify suspected cases of bioterrorism, with the internet used to report, confirm, and prevent outbreaks.

PURPOSE: To determine the prevalence of use of complementary/alternative medicine (CAM) by breast cancer survivors in Ontario, Canada, and to compare the characteristics of CAM users and CAM nonusers. PATIENTS AND METHODS: A questionnaire was mailed to a random sample of Ontario women diagnosed with breast cancer in 1994 or 1995. RESULTS: The response rate was 76.3%. Overall, 66.7% of the respondents reported using CAM, most often in an attempt to boost the immune system. CAM practitioners (most commonly chiropractors, herbalists, acupuncturists, traditional Chinese medicine practitioners, and/or naturopathic practitioners) were visited by 39.4% of the respondents. In addition, 62.0% reported use of CAM products (most frequently vitamins/minerals, herbal medicines, green tea, special foods, and essiac). Almost one half of the respondents informed their physicians of their use of CAM. Multiple logistic regression analysis determined that support group attendance was the only factor significantly associated with CAM use. CONCLUSION: CAM use is common among Canadian breast cancer survivors, many of whom are discussing CAM therapy options with their physicians. Knowledge of CAM therapies is necessary for physicians and other health care practitioners to help patients make informed choices. CAM use may play a role in the positive benefits associated with support group attendance.

Hemodynamic changes associated with the administration of protamine were studied in 30 dogs divided into three equal groups. Protamine (1 mg X kg-1 X min-1 for 4 min) was administered 10 min after 4 mg X hg-1 heparin was given via a left atrial (LA) line in group A, via a central vein in group B, and via a peripheral vein in group C. Protamine given through the central venous pressure (CVP) line resulted in an immediate and significant decrease in mean arterial pressure (MAP) to 60 +/- 4.5 mm Hg (P less than 0.025) from 72 +/- 7 mm Hg immediately after the protamine and to 58 +/- 5 mm Hg (P less than 0.025) 5 min later and with an increase in cardiac index (CI) to 3.7 +/- 0.3 L X min-1 X m-2 from 2.8 +/- .25 L X min-1 X m-2 immediately after the protamine (P less than 0.005), followed by a decrease back to 2.7 +/- 0.3 L X min-1 X m-2 5 min later. Mean arterial pressure and CI remained unchanged after administration of protamine via the peripheral vein or the left atrium. Systemic vascular resistance (SVR) decreased significantly only after administration of protamine via the CVP and was statistically unchanged when administered via the peripheral and LA line. Plasma histamine levels increased significantly after administration of protamine through the central line but remained unchanged after administration via a peripheral vein or the left atrium.(ABSTRACT TRUNCATED AT 250 WORDS)
