La Vaque and Rossiter made a strong, supported argument that it is unethical to use a no treatment control group in a research study if a known, effective treatment is available. Their argument is based on the supposition that the Declaration of Helsinki is the ethical world standard for research with humans. Their argument appears to be straightforward, but is not simple to apply. The issues are very complex, include issues not discussed in their argument, and can lead to a different conclusion as pointed out in this paper. The World Medical Association developed the Declaration of Helsinki as one of their official policies. The Declaration of Helsinki, however, is not accepted as the world ethical standard, as demonstrated by its lack of adoption by many professional associations or even by the United States Federal Government. Perhaps it is not mentioned because its ethical provisions are aspirational rather than mandatory as implied by La Vaque and Rossiter. Researchers and clinicians should also be aware of other ethical issues not directly discussed in the La Vaque and Rossiter paper. The Belmont Report is the basis for the ethical protection of human research subjects for at least 17 federal agencies and does not mention the Declaration of Helsinki. The Belmont Report mentions several ethical principles that form the basis for informed consent, risk/benefit assessment, confidentiality of data, subject selection, Institutional Review Boards, and other protections needed when doing research with human subjects. At least 2 of these core principles have direct implications to the discussion related to the use of placebo controls. The ethical principle of fidelity is also important in guiding research activities with human subjects. Researchers should be familiar with the La Vaque and Rossiter argument, the Belmont Report, and the federal policies developed to implement the provisions of that report, for example, Regulation 45 CFR 46.  相似文献

The general aim of this article is to give a critical interpretation of post‐trial obligations towards individual research participants in the Declaration of Helsinki 2013. Transitioning research participants to the appropriate health care when a research study ends is a global problem. The publication of a new version of the Declaration of Helsinki is a great opportunity to discuss it. In my view, the Declaration of Helsinki 2013 identifies at least two clearly different types of post‐trial obligations, specifically, access to care after research and access to information after research. The agents entitled to receive post‐trial access are the individual participants in research studies. The Declaration identifies the sponsors, researchers and host country governments as the main agents responsible for complying with the post‐trial obligations mentioned above. To justify this interpretation of post‐trial obligations, I first introduce a classification of post‐trial obligations and illustrate its application with examples from post‐trial ethics literature. I then make a brief reconstruction of the formulations of post‐trial obligations of the Declaration of Helsinki from 2000 to 2008 to correlate the changes with some of the most salient ethical arguments. Finally I advance a critical interpretation of the latest formulation of post‐trial obligations. I defend the view that paragraph 34 of ‘Post‐trial provisions’ is an improved formulation by comparison with earlier versions, especially for identifying responsible agents and abandoning ambiguous ‘fair benefit’ language. However, I criticize the disappearance of ‘access to other appropriate care’ present in the Declaration since 2004 and the narrow scope given to obligations of access to information after research.  相似文献

Recent technological developments have considerably transformed the supply, storage, and transportation processes of cadavers, creating new and previously unforeseen ethical challenges regarding cadaver usage. In this study, we analyzed two aspects of the cadaver processing system—cadaver supply and its use in research. Thereafter, we highlighted the major ethical concerns underlying these stages and correlated our search results with the ethical principles outlined in the Declaration of Helsinki (DoH), or Helsinki Declaration. To ensure the reliability and continuity of medical progress, human—especially cadaver—research depends on the ethical priorities as outlined in the DoH: respect for autonomy, privacy/confidentiality, risks/burdens/benefits, and the protection of vulnerable groups. According to our ethics analysis, which also corresponds with the ethics guidelines of the Consensus Panel on Research with the Recently Dead, the most ignored values were respect for autonomy and privacy/confidentiality issues. Based on these ethical concerns, we provide recommendations to address these challenges in anatomy research.  相似文献

The effects of distant, intercessory prayer on health outcomes have been studied in a range of randomised, blinded clinical trials. However, while seeking the evidentiary status accorded this 'gold standard' methodology, many prayer studies fall short of the requirements of the World Medical Association's Declaration of Helsinki for the ethical conduct of trials involving human subjects. Within a sample of 15 such studies published in the medical literature, many were found to have ignored or waived key ethical precepts, including adequate standards of care, patient confidentiality and informed consent. Prayer was considered in most studies to pose negligible or no risk to subjects, despite the fact that no clear mechanism of action nor any safety monitoring procedures were described. As a result, many studies did not meet basic ethical standards required of clinical trials of biophysical interventions, making application of their results ethically problematic. If investigators wish their data to adequately inform the use or rejection of intercessory prayer to improve health, these shortcomings should be addressed in future studies.  相似文献

Ethics in biomedical research took off from the 1947 Nuremberg Code to its own right in the wake of the Declaration of Helsinki in 1964. Since then, (inter)national regulations and guidelines providing a framework for clinical studies and protection for study participants have been drafted and implemented, while ethics committees and drug evaluation agencies have sprung up throughout the world. These two developments were crucial in bringing about the protection of rights and safety of the participants and harmonization of the conduct of biomedical research. Ethics committees and drug evaluation agencies deliver ethical and scientific assessments on the quality and safety of the projects submitted to them and issue respectively approvals and authorizations to carry out clinical trials, while ensuring that they comply with regulatory requirements, ethical principles, and scientific guidelines. The advent of biomedical ethics, together with the responsible commitment of clinical investigators and of the pharmaceutical industry, has guaranteed respect for the patient, for whom and with whom research is conducted. Just as importantly, it has also ensured that patients reap the benefit of what is the primary objective of biomedical research: greater life expectancy, well-being, and quality of life.  相似文献

Update on unethical use of placebos in randomised trials   总被引:1,自引:0,他引:1  
Michels KB  Rothman KJ 《Bioethics》2003,17(2):188-204
The most recent (Fifth) revision of the Declaration of Helsinki, adopted in October 2000 by the World Medical Association (WMA), reinforces the longstanding prohibition against offering placebo instead of effective therapy. The WMA left no doubt that if a beneficial treatment for a condition has already been recognised, it is unethical to offer placebo in place of such treatment to anyone in a study of the same condition. We have previously drawn attention to the discrepancy between the spirit of the Declaration and the common practice of using placebo controls in randomised trials even if effective treatment exists. Despite the mandates of the Declaration of Helsinki and concern from ethicists and scientists, the US Food and Drug Administration (FDA) continues to demand and defend placebo-controlled evidence of efficacy and safety for the development of many new pharmaceuticals, even if effective therapy exists. We suggest that the FDA's arguments defending their practice are insufficient to justify medical research that violates the Declaration of Helsinki.  相似文献

The question of the use of the placebo is one of the most controversial in the field of the ethics of research today. The use of the placebo remains the standard practice of biomedical research in spite of the fact that various revisions of the Helsinki Declaration have sought to limit its use. In Canada, the Tri-council policy statement: Ethical conduct for research involving humans adopted a very restrictive position with respect to the use of placebos, precisely defining the situations in which its use would meet the demands of ethical research. The positions taken by the various ethical decision-making bodies are, however, hardly shared by regulatory bodies such as the Food and drug administration (FDA), the Council for international organization of medical sciences (CIOMS) or the European agency for the evaluation of medicinal products (EMEA). This divergence of opinions reveals two quite different conceptions of what constitutes the ethical. In the case of decision-making bodies in the ethical field, it is clearly medicine's Hippocratic Oath which explains their reluctance to use placebos. The first responsibility of the doctor is to "do no harm" to his or her patient. This duty is inherent to the medical profession and as such is not grounded in the view of medicine as a contract for care. In the case of regulatory bodies, it is the vision of "medicine as contract" which is in view; and it is this notion that justifies the use of placebos once free and informed consent has been obtained. It is also worth noting that these regulatory bodies make frequent use of arguments based on utilitarian ends. In an unprecedented move, the World medical association published in October 2001 a clarification note about the use of placebos. An analysis of this text raises the question about its real meaning: clarification or concession?  相似文献

The Universal Draft Declaration on Bioethics and Human Rights seeks to provide moral direction to nations and their citizens on a series of bioethical concerns. In articulating principles, it ranks respect for human rights, human dignity and fundamental freedoms ahead of respect for cultural diversity and pluralism. This ranking is controversial because it entails the rejection of the popular theory, conventionalist ethical relativism. If consistently defended, this theory also undercuts other United Nations activities that assume member states and people around the world can reach trans-cultural judgments having moral authority about health, pollution, aggression, rights, slavery, and so on. To illustrate problems with conventionalist ethical relativism and the importance of rejecting it for reasons of health, human rights, human dignity and fundamental freedoms, the widespread practice of female genital circumcision or cutting is discussed. These surgeries are virtually a test case for conventionalist ethical relativism since they are widely supported within these cultures as religious and health practices and widely condemned outside them, including by the United Nations.  相似文献

Both human research and animal research operate within established standards and procedures. Although the human research environment has been criticized for its sometimes inefficient and imperfect process, reported abuses of human subjects in research served as the impetus for the establishment of the Nuremberg Code, Declaration of Helsinki, and the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research and the resulting Belmont Report. No similar, comprehensive and principled effort has addressed the use of animals in research. Although published policies regarding animal research provide relevant regulatory guidance, these policies have not emerged from the process of specifying consistent and reasoned ethical principles. The lack of a fundamental effort to explore the ethical issues and principles regarding the use of animals in research has led to unclear and disparate policies. Recent studies have increased our understanding of animal cognition and emotion, suggesting that animals' potential for experiencing a wide variety of harms, such as pain and fear, is greater than has been previously appreciated. Furthermore, relationships between methods of captivity and certain laboratory procedures and the resulting adverse physical, social and psychological effects have been established. In light of this information, current protections may need to be reconsidered and modified. This paper explores the historical convergence and divergence in the creation of human and animal research guidelines, as well as opportunities to align ethical frameworks with new scientific discoveries.  相似文献

A frequent missense mutation (Thr-6Pro) found in the prepeptide of the lysosomal acid lipase (LAL) gene was analyzed in a cohort of 1003 randomly selected samples from Germany, Japan and Sardinia (Italy). Using the mutagenically separated polymerase chain reaction (MS-PCR), allele frequencies of 0.269, 0.238 and 0.245 were determined in the three populations, respectively. Statistical analysis showed a lack of association with a dyslipidemic phenotype in all three groups. Additionally, in a subgroup of 126 German individuals no association was observed between genotype and LAL activity. We conclude that this mutation appears to be a frequent LAL gene polymorphism causing no impaired function of the enzyme and no measurable dyslipidemia in the general population.This study was performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki  相似文献

Some of the recent criticisms published during and after the last revision process of the Declaration of Helsinki are directed at its basic legitimacy. In this article we want to have a closer look at the two criticisms we consider to be the most fundamental. The first criticism questions the legitimate authorship of the World Medical Association to publish a document such as the Declaration. The second fundamental criticism we want to examine argues that the last revision process failed to meet the standards for fair, democratic procedures. Although both criticisms deny the formal legitimacy of the Declaration in the most fundamental way, they have never been addressed in detail in a single article. We refute most of the related arguments. However, acknowledging some of the points made, improvements for future revision processes and versions of the Declaration of Helsinki are outlined.  相似文献

The article aims to illuminate the recent debate in Germany about the legitimacy of circumcision for religious reasons. The aim is both to evaluate the new German law allowing religious circumcision, and to outline the resulting conflict between the surrounding ethical and legal issues. We first elucidate the diversity of legal and medical views on religious circumcision in Germany. Next we examine to what extent invasive and irreversible physical interventions on infant boys unable to given their consent should be carried out for non‐medical reasons. To this end, the potential benefits and harms of circumcision for non‐medical reasons are compared. We argue that circumcision does not provide any benefits for the ‘child as a child’ and poses only risks to boys. We then set out to clarify and analyse political (rather than ethical) justifications of the new circumcision law. We demonstrate through this analysis how the circumcision debate in Germany has been transformed from a legal and ethical problem into a political issue, due at least in part to Germany's unique historical context. Although such a particular political sensibility is entirely comprehensible, it raises particular problems when it comes to framing and responding to medical ethical issues – as in the case of religious circumcision.  相似文献

Deficiency of lysosomal acid lipase is expressed in two distinct recognizable phenotypes. Wolman disease represents the severe early onset form, whereas cholesterol ester storage disease is the more benign late onset type. Previous studies have indicated that compound heterozygosity consisting of a G A mutation at the 3 splice junction of exon 8 (E8SJM-allele) together with a null allele of the gene encoding lysosomal acid lipase leads to cholesterol ester storage disease. We have now observed homozygosity for the G A splice junction mutation in a non-related Spanish kindred with the same disease. As expected, the residual activity of lysosomal acid lipase is higher in this case, suggesting that the E8SJM-allele is associated with low residual acid lipase activity. However, the phenotype of the homozygous propositus is more severe compared with the previously described case, indicating that no direct relationship exists between the genotype or residual LAL activity and the precise cholesterol or triglyceride levels in a given patient. Nevertheless, our findings provide convincing evidence that homozygosity for the E8SJM-allele causes cholesterol ester storage disease to at least the same extent as compound heterozygosity consisting of this allele and a null allele.This study was performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki  相似文献

One of the most challenging issues in cross‐cultural bioethics concerns the long‐standing socio‐cultural practice of female genital circumcision (FGC), which is prevalent in many African countries and the Middle East as well as in some Asian and Western countries. It is commonly assumed that FGC, in all its versions, constitutes a gross violation of the universal human rights of health, physical integrity, and individual autonomy and hence should be abolished. This article, however, suggests a mediating approach according to which one form of FGC, the removal of the clitoris foreskin, can be made compatible with the high demands of universal human rights. The argument presupposes the idea that human rights are not absolutist by nature but can be framed in a meaningful, culturally sensitive way. It proposes important limiting conditions that must be met for the practice of FGC to be considered in accordance with the human rights agenda.  相似文献

With the growing incidence of HIV, there is a desperate need to develop simple, cheap and effective new ways of preventing HIV infection. Male circumcision reduces the risk of infection by about 60%, probably because of the removal of the Langerhans cells which are abundant in the inner foreskin and are the primary route by which HIV enters the penis. Langerhans cells form a vital part of the body's natural defence against HIV and only cause infection when they are exposed to high levels of HIV virions. Rather than removing this natural defence mechanism by circumcision, it may be better to enhance it by thickening the layer of keratin overlying the Langerhans cells, thereby reducing the viral load to which they are exposed. We have investigated the ability of topically administered oestrogen to induce keratinization of the epithelium of the inner foreskin. Histochemically, the whole of the foreskin is richly supplied with oestrogen receptors. The epithelium of the inner foreskin, like the vagina, responds within 24 hours to the topical administration of oestriol by keratinization, and the response persists for at least 5 days after the cessation of the treatment. Oestriol, a cheap, readily available natural oestrogen metabolite, rapidly keratinizes the inner foreskin, the site of HIV entry into the penis. This thickening of the overlying protective layer of keratin should reduce the exposure of the underlying Langerhans cells to HIV virions. This simple treatment could become an adjunct or alternative to surgical circumcision for reducing the incidence of HIV infection in men.  相似文献

Medical ethicists have questioned the use of no-treatment (placebo and sham procedure) controlled studies of new therapies when safe and effective standard therapies are available for use as an active or equivalence control. Current ethical principles of conduct for biomedical research specifically prohibit designs that withhold or deny the best proven diagnostic and therapeutic treatment to any participant in a clinical study, including those individuals who consent to randomization into a control group. Studies of psychophysiological therapies are often criticized on the grounds they lack a placebo or sham treatment control group. This paper briefly reviews the history of the problem and discusses the ethical standards that govern human research as derived from the Nuremberg Code and the Declaration of Helsinki. An examination of the problem with regard to research involving EEG biofeedback therapy for Attention-Deficit/Hyperactivity Disorder, Traumatic Brain Injury, and depression serves to highlight the issues. It is concluded that the active treatment control (treatment equivalence) design is most appropriate for those clinical studies examining disorders for which there is a known, effective treatment. Sham- or placebo-controlled studies are ethically acceptable for those disorders for which no effective treatment is available.  相似文献

In most boys referred for circumcision preputial adhesions are the only problem, but these can predispose to recurrent balanitis. A simple technique using Emla cream (eutectic mixture of lignocaine and prilocaine) has been devised which allows the adhesions to be separated painlessly in the outpatient clinic. The technique was used on 39 boys aged 2 to 12 years referred for circumcision, none of whom had a retractable foreskin. The cream was applied under an occlusive dressing and left for 60 minutes before the adhesions were separated with a probe and a gauze swab. The procedure was completely pain free in 32 boys. One boy had to undergo a repeated procedure because he failed to follow the advice regularly to retract his foreskin in the three weeks after the procedure. Only one boy had to undergo circumcision later because of fibrous phimosis. In many boys referred for circumcision separation of preputial adhesions is all that is needed, and the use of this local anaesthetic technique avoids the need for general anaesthesia.  相似文献

Introduction

Circumcision is still the most commonly performed surgery in our society. It??s often performed by an unlicensed paramedic or even by a traditional practitioner outside the hospital under the non sterile conditions. Although, not technically difficult, circumcision may have serious complications that can endanger the sexuality or even the life of male children. The aim of this study is to emphasize the important problem of glandular amputation after circumcision.

Patients and methods

We report 8 cases of glandular amputation after circumcision performed outside the hospital within traditional methods.

Results

The mean age of these patients was 6 years (3 to 8 years). Glandular amputation occurred during circumcision in 4 cases including that 2 cases with total glandular amputation. On the other cases it was about glandular necrosis caused by inadequate use of electric lancet. An urgent reparation of glans was performed on only 3 cases. On the forth the amputed glans was unrepairable. We noticed only one case on wich glans revascularization succeeded. In case of glandular necrosis, patients consulted after 3 days. The treatment consisted of meatoplasty.

Conclusion

Glandular amputation is a rare but very severe complication of circumcision because it endangers the future sexuality of the child. So, the operation should be performed by educated and experienced personnel.  相似文献
