Reduction ascending aortoplasty has been advocated as a possible alternative to traditional graft replacement for treatment of aneurysms of the ascending aorta and root. We report a case of a 58-year-old Jehovah's Witness female, with a 5.5-cm ascending aortic aneurysm and critical aortic stenosis. She underwent aortic valve replacement and reduction aortoplasty buttressed with a Dacron graft. We reviewed the history and contemporary applications of this technique and concluded that aortic reduction with externally supported aortoplasty may represent a viable option to treat Jehovah's Witness patients with ascending aorta and root aneurysm.

The increasingly frequent practice of autohemotherapy entails a potential risk to the health of individuals since it is scientifically unproven. There are practically no clinical studies showing the efficacy and safety of this procedure; only experimental research with questionable results from studies on human beings and animals. Over the last years, the sanitary surveillance area has expanded its preventive and risk control actions based upon a precautionary philosophy in the private as well as the public sphere. By observing the theoretical and practical reference points of the "four Ps" (prevention, protection, precaution and prudence), in accordance with the epistemology developed within Intervention Bioethics, sanitary surveillance actions are based upon legal administrative policing powers. These powers are understood to be the Public Administration's competence to set conditions on and restrict the use and benefit of goods, activities and individual rights, on behalf of the common well being of people or the State itself. The Brazilian State, through its sanitary surveillance policing powers at the three levels of government, has intervened in the practice of autohemotherapy. Considering the responsible State intervention in situations of collective interest, vulnerability and susceptibility, the present study proposed to analyze the practice of autohemotherapy in the light of sanitary surveillance actions and their relationship with the "four Ps" of Intervention Bioethics.

Autologous blood transfusion grew in popularity in response to the recognition of transfusion-transmitted HIV and a lack of effective screening. Laboratory screening and donor deferrals have decreased the need for autologous transfusion. The issue of banking blood that has not been tested or has been tested and found positive for serious infectious diseases raises ethical and legal issues that must be addressed by transfusion services, transfusion committees, physicians, and administrators. This article provides a summary of pertinent federal and state laws regarding autologous blood transfusion and a framework to assess the ethical implications of various strategies.

Chairman to the French Institutional Review Board, Professor Didier Sicard raises blood donation issues from an ethical standpoint. The contaminated blood scandal focused on the necessity of reducing transfusion risks and regarded blood safety as an ethical mandatory requirement, a debatable subject to deal with. The author proposes to reconsider the nature of unpaid blood donations while advising not to scorn the remunerated gift when such is the case. As for the use of blood, he questions the solutions based on a zero risk perspective, in particular an excessive auto-transfusional practice or a restrictive use of blood, lately regarded as essential. Starting from the blood donation concern this article leads us to think over both our society's fears and the precautionary principle abuses.
