Human guinea pigs and the ethics of experimentation: the BMJ's correspondent at the Nuremberg medical trial.

Though the Nuremberg medical trial was a United States military tribunal, British forensic pathologists supplied extensive evidence for the trial. The BMJ had a correspondent at the trial, and he endorsed a utilitarian legitimation of clinical experiments, justifying the medical research carried out under Nazism as of long term scientific benefit despite the human costs. The British supported an international medical commission to evaluate the ethics and scientific quality of German research. Medical opinions differed over whether German medical atrocities should be given publicity or treated in confidence. The BMJ''s correspondent warned against medical researchers being taken over by a totalitarian state, and these arguments were used to oppose the NHS and any state control over medical research.     

Not a slippery slope or sudden subversion: German medicine and national socialism in 1933.

The history of medicine this century is darkened by the downfall of the German medical profession, exposed during the doctors'' trial at Nuremberg in 1946. Relying largely on documents published during 1933 in German medical journals, this paper examines two widely accepted notions of those events, metaphorically termed "slippery slope" and "sudden subversion." The first connotes a gradual slide over infinitesimal steps until, suddenly, all footing is lost; the second conveys forced take over of the profession''s leadership and values. Both concepts imply that the medical profession itself became the victim of circumstances. The slippery slope concept is a prominent figure of argument in the current debate on bioethics. The evidence presented here, however, strongly suggests that the German medical community set its own course in 1933. In some respects this course even outpaced the new government, which had to rein in the profession''s eager pursuit of enforced eugenic sterilizations. In 1933 the convergence of political, scientific, and economic forces dramatically changed the relationship between the medical community and the government. That same convergence is occurring again and must be approached with great caution if medicine is to remain focused on the preservation of physical and medical integrity.     

Medical ethics in the wake of the Holocaust: departing from a postwar paper by Ludwik Fleck

In 1948 Ludwik Fleck published a paper in Polish discussing the use of humans in medical experiments, thereby addressing his peers. Though the paper has so far not been translated or studied, it has been taken to indicate Fleck's deep commitment to ethical questions, notably the question of informed consent. In being written by a former victim of the Nazi policy and a survivor of the Holocaust also acting as an expert witness in the trial of the IG Farben in Nuremberg, the paper is of interest. A scrutiny of Fleck's text and related sources discloses, however, not only the complexity of the issue at the centre of the Nuremberg trial, but also Fleck's unexpected stance in seemingly adducing his arguments from both the German defendants and the prosecution, heavily informed by US scientists. Further, the contentious discussion of the past in Fleck's paper reveals its links to modern bioethical discussion. Though sometimes oblivious of that past, it still faces the same questions.     

The ethics of learning from patients

Is it ethical for medicine to use patients as learning tools for medical students if these patients have not been given a chance to provide truly informed consent? Dr. Caroline Shooner raises this question in the following article, which claimed second prize in CMAJ''s 1996 Logie Medical Ethics Essay Contest. She considers the case of a patient whose trust was shaken when a medical student performed a chest-tube insertion. Shooner concludes that psychologic harm could have been avoided had the patient''s right to informed consent been respected. She also argues that few patients will turn down a chance to help students learn if the request is made properly and openly.     

Informed consent in human experimentation before the Nuremberg code.

The issue of ethics with respect to medical experimentation in Germany during the 1930s and 1940s was crucial at the Nuremberg trials and related trials of doctors and public health officials. Those involved in horrible crimes attempted to excuse themselves by arguing that there were no explicit rules governing medical research on human beings in Germany during the period and that research practices in Germany were not different from those in allied countries. In this context the Nuremberg code of 1947 is generally regarded as the first document to set out ethical regulations in human experimentation based on informed consent. New research, however, indicates that ethical issues of informed consent in guidelines for human experimentation were recognised as early as the nineteenth century. These guidelines shed light on the still contentious issue of when the concepts of autonomy, informed consent, and therapeutic and non-therapeutic research first emerged. This issue assumes renewed importance in the context of current attempts to assess liability and responsibility for the abuse of people in various experiments conducted since the second world war in the United States, Canada, Russia, and other nations.     

Letter to my future doctor

Everyone is talking. Physicians, politicians, newspaper columnists, patients, families, authors, talk show hosts, all are debating our right to decide how and when we will die. It is necessary and wise to obtain a medical directive. One question we must ask ourselves as physicians is, Can we do what we ask our patients to do? Here is one physician''s medical directive.     

PBL教学模式在内科临床教学的应用探讨

内科是临床科室的重要组成部分,内科教学是为培养医务工作者的重要步骤,是医学生由学生向医生角色转变的桥梁。传统临床教学以知识灌输为主,学生学习积极性较低,教学质量较低。上世纪60、70年代问题导向(PBL)的教学方法被提出,为教学改革提供了一个全新的思路。本文将PBL教学方法应用于内科临床教学工作中,结合本学科的特点,以学生为中心,以问题为向导,充分发挥学生的学习积极性,提高教学质量,促进学生主动学习能力提高,帮助医学生建立完整的内科诊疗过程思维,进而达到临床内科教学目标。     

THE ROLE OF GOVERNMENT IN MEDICINE

On the fundamental question of how far a government should be involved in health services, the author believes these things can appropriately be said: The government should continue to assume complete control over public health measures, and public health officials could well be permitted to invade medical services insofar as is necessary to achieve public health ends.To assist in the production of medical personnel, it is also fitting for the government to provide for increased teaching facilities, higher salaries for teachers in the medical field and scholarships for worthy students.In the area of insurance and prepayment plans, a really intelligent supervision of such devices, with the exercise of no more arbitrary governmental power than is now used by the various other regulatory commissions, is a suitable governmental function. The government''s buying policies for its wards, rather than providing direct medical services for them, should be encouraged. This would give the private practice of medicine a boost and would improve the quality of medical care. Government should encourage the regionalization of medical services with as much of the actual controls exercised at the local level as can be achieved. Private means should be utilized for the provision of these services and public means should be used for their payment when this is an obligation of the government.The problem of mass education in health matters should be tackled by government. It would be a fine thing if the medical profession and governmental agencies could agree upon delineation of their respective roles in the health field.Because further experimentation is needed before the ideal solution is found, both government and organized medicine should encourage the exploration of new approaches.     

Trends in health research ethics in the Philippines during the American Colonial Period (1898‐1946)

Research involving human participants has been conducted in the Philippines since the beginning of the Spanish colonial period. Such studies are expected to adhere to internationally accepted ethical guidelines. This paper discusses trends in clinical research ethics in the Philippines during the American colonial period (1898‐1946). Specifically, studies were assessed on: 1) their observance of ethical protocols, including review; 2) identification of inclusion and exclusion criteria in the selection of participants; 3) use of vulnerable subjects; and 4) practice of the informed consent process. Only the informed consent process had a significant logistic correlation with progression of years. Recruitment of vulnerable groups was common during this period; children and prisoners were the most common participants. Trends in medical ethics in the Philippines reflected those in the United States prior to the publication of the Nuremberg Code, which served as a milestone in the protection of human welfare in clinical research.     

GOING FROM PRINCIPLES TO RULES IN RESEARCH ETHICS

In research ethics there is a canon regarding what ethical rules ought to be followed by investigators vis‐à‐vis their treatment of subjects and a canon regarding what fundamental ethical principles apply to the endeavor. What I aim to demonstrate here is that several of the rules find no support in the principles. This leaves anyone who would insist that we not abandon those rules in the difficult position of needing to establish that we are nevertheless justified in believing in the validity of the rules. I conclude by arguing that this is not likely to be accomplished. The rules I call into question are the rules requiring:

• – that studies be designed in a scientifically valid way
• – that risks to subjects be minimized
• – that subjects be afforded post‐trial access to experimental interventions
• – that inducements paid to subjects not be counted as a benefit to them
• – that inducements paid to subjects not be ‘undue’
• – that subjects must remain free to withdraw from the study at any time for any reason without penalty

Both canons, the canon on principles and the canon on rules, are found in the overlap among ethical pronouncements that are themselves canonical: the Nuremberg Code, the Declaration of Helsinki, the Belmont Report, CIOMS's International Ethical Guidelines for Biomedical Research Involving Human Subjects, and NBAC's 2001 report, Ethical Issues in International Research: Clinical Trials in Developing Countries.     

Do physicians have an ethical obligation to care for patients with AIDS?

This paper responds to the question: Do physicians have an ethical obligation to care for patients with acquired immunodeficiency syndrome (AIDS)? First, the social and political milieu in which this question arises is sampled. Here physicians as well as other members of the community are found declaring an unwillingness to be exposed to people with AIDS. Next, laws, regulations, ethical codes and principles, and the history of the practice of medicine are examined, and the literature as it pertains to these areas is reviewed. The obligation to care for patients with AIDS, however, cannot be located in an orientation to morality defined in rules and codes and an appeal to legalistic fairness. By turning to the orientation to morality that emerges naturally from connection and is defined in caring, the physicians'' ethical obligation to care for patients with AIDS is found. Through an exploration of the writings of modern medical ethicists, it is clear that the purpose of the practice of medicine is healing, which can only be accomplished in relationship to the patient. It is in relationship to patients that the physician has the opportunity for self-realization. In fact, the physician is physician in relationship to patients and only to the extent that he or she acts virtuously by being morally responsible for and to those patients. Not to do so diminishes the physician''s ethical ideal, a vision of the physician as good physician, which has consequences for the physician''s capacity to care and for the practice of medicine.     

Partiality,impartiality and the ethics of triage

In this paper, I discuss the question of partiality and impartiality in the application of triage. Triage is a process in medical research which recommends that patients should be sorted for treatment according to the degree or severity of their injury. In employing the triage protocol, however, the question of partiality arises because socially vulnerable groups will be neglected since there is the likelihood that the social determinants of a patient's health may diminish her chance of survival. As a process that is based on the severity of a patient's injury, triage will be unfair, and hence negatively partial, to socially vulnerable people. Thus, I aim in this paper to show that the triage protocol fails as an impartial evaluative process because its only aim is to maximize survivability. I contend that: (i) triage would lead to the neglect of the social condition of patients or victims, and (ii) it will only serve the utilitarian purpose of maximization of outcomes which may not be justified in some cases.     

Does benefit justify research with children?

The inclusion of children in research gives rise to a difficult ethical question: What justifies children's research participation and exposure to research risks when they cannot provide informed consent? This question arises out of the tension between the moral requirement to obtain a subject's informed consent for research participation, on the one hand, and the limited capacity of most children to provide informed consent, on the other. Most agree that children's participation in clinical research can be justified. But the ethical justification for exposing children to research risks in the absence of consent remains unclear. One prevalent group of arguments aims to justify children's risk exposure by appealing to the concept of benefit. I call these ‘benefit arguments’. Prominent versions of this argument defend the idea that broadening our understanding of the notion of benefit to include non‐medical benefits (such as the benefit of a moral education) helps to justify children's research participation. I argue that existing benefit arguments are not persuasive and raise problems with the strategy of appealing to broader notions of benefit to justify children's exposure to research risk.     

The diagnostic process: a comparison of scanning techniques.

In choosing between various scanning techniques the factors to be considered include availability, cost, the type of equipment, the expertise of the medical and technical staff, and the inherent capabilities of the system. Although it is difficult to state dogmatically which scanning technique is best for each patient and condition, one or other technique is clearly preferable in some areas of medicine. Ultrasound, for example, should be used in obstetrics, while computerized tomography has revolutionised neuroradiological diagnosis. Nevertheless, there is still no substitute for good history taking and a thorough physical examination. The most important factor determining the choice of technique is the system''s ability to answer the specific question required for the management of the patient.     

Physicians' Characteristics Associated with Exploring Suicide Risk among Patients with Depression: A French Panel Survey of General Practitioners

Background

General practitioners (GPs) have a key role to play in suicide prevention, but the rates at which they question patients with depression about suicidal thoughts and plans are rather low. Little is known about GPs'' characteristics associated with such inquiries. Our objectives were to describe GPs'' attitudes, perceived barriers, and self-reported practices in this questioning of these patients and to analyze factors associated with these practices.

Methodology

This cross-sectional survey was conducted among participants in a panel of randomly selected French GPs (1249/1431 participated: 87.3%). GPs were interviewed with a standardized questionnaire covering their professional and personal characteristics, attitudes, and practices in exploring the suicide risk of their patients with depression. We built a suicide inquiry score by summing the responses to 5 items and used a multiple linear regression analysis to explore the characteristics associated with this score.

Principal Findings

Most GPs reported inquiring about the presence of suicidal ideation often or very often; less than 30% reported that they frequently explored signs of a specific suicide plan. The mean suicide inquiry score was 12.4 (SD, 2.9; range, 5–20). False ideas, such as thinking that patients who report suicidal ideas do not often commit suicide, were frequent (42.3%). Previous continuing medical education on suicide, participation in a formal mental health network, and patients who committed suicide in the past 5 years were associated with a higher score. Reluctance to question patients about suicide and perception of insufficient skill were associated with a lower score.

Conclusions/Significance

This study showed great variability in French GPs'' practices in exploring suicide risk in patients with depression. Interventions aiming at improving GPs'' initial training and continuing medical education in suicide and/or depression, and their collaboration with mental health specialists should be developed, and their impacts assessed.     

Zuchterfolg des Riesenseeadlers,Haliaeetus pelagicus,im Tierpark Berlin mit einem Weibchen der dunklen Morphe

Tierpark Berlin is keeping Steller's Sea Eagles since 1959 continuously without any breeding success till 2009. There was one egg laid in 1962 only. In 2001 we received a female from Tiergarten Nuremberg. At seven years of age this bird has moulted into its adult plumage this being all dark brown apart from the white tail. This is the only known present living specimen of this dark morph and the first known for several decades. As the parents show the normal coloured plumage this is the first evidence that niger doesn’t exist as a subspecies but is a dark colour phase of pelagicus only. The dark coloured female was breeding with a normal coloured male in 2009 and one offspring was parent reared for the first time at Tierpark Berlin.     

Implications of managed care for health systems,clinicians, and patients.

The rhetoric and realities of managed care are easily confused. The rapid growth of managed care in the United States has had many implications for patients, doctors, employers, state and federal programmes, the health insurance industry, major medical institutions, medical research, and vulnerable patient populations. It has restricted patients'' choice of doctors and limited access to specialists, reduced the professional autonomy and earnings of doctors, shifted power from the non-profit to the for-profit sectors and from hospitals and doctors to private corporations. It has also raised issues about the future structuring and financing of medical education and research and about practice ethics. However, managed care has also accorded greater prominence to the assessment of patient satisfaction, profiling and monitoring of doctors'' work, the use of clinical guidelines and quality assurance procedures and indicated the potential to improve the integration and outcome of care.     

Understanding physicians' response to AIDS.

Attempts to comprehend physicians'' extreme reaction to AIDS (acquired immune deficiency syndrome) have met with great difficulty since the disease brings into question traditional norms and assumptions. As the medical profession struggles to develop guidelines and policies to help it deal with this disease, it can draw on very little systematic research on the effect of AIDS on physicians'' attitudes and practices. We suggest a framework developed from the literature on physicians'' and society''s response to other disorders that would provide a basis for organizing the ever-increasing amount of information on physicians and AIDS and would guide systematic research aimed at understanding and predicting physicians'' participation in the prevention and management of AIDS. Within this framework we consider how characteristics of the disease, elements of the health care system and physicians'' attitudes interact to influence clinical and personal practices. AIDS had led to new delineations of physicians'' responsibility, modification of prevailing beliefs about physician autonomy and thus a redefinition of the role of the physician in North America.     

Consumer demand for caesarean sections in Brazil: informed decision making,patient choice,or social inequality? A population based birth cohort study linking ethnographic and epidemiological methods

ObjectivesTo investigate why some women prefer caesarean sections and how decisions to medicalise birthing are influenced by patients, doctors, and the sociomedical environment.DesignPopulation based birth cohort study, using ethnographic and epidemiological methods.SettingEpidemiological study: women living in the urban area of Pelotas, Brazil who gave birth in hospital during the study. Ethnographic study: subsample of 80 women selected at random from the birth cohort. Nineteen medical staff were interviewed.Participants5304 women who gave birth in any of the city''s hospitals in 1993.ResultsIn both samples women from families with higher incomes and higher levels of education had caesarean sections more often than other women. Many lower to middle class women sought caesarean sections to avoid what they considered poor quality care and medical neglect, resulting from social prejudice. These women used medicalised prenatal and birthing health care to increase their chance of acquiring a caesarean section, particularly if they had social power in the home. Both social power and women''s behaviour towards seeking medicalised health care remained significantly associated with type of birth after controlling for family income and maternal education.ConclusionsFear of substandard care is behind many poor women''s preferences for a caesarean section. Variables pertaining to women''s role in the process of redefining and negotiating medical risks were much stronger correlates of caesarean section rates than income or education. The unequal distribution of medical technology has altered concepts of good and normal birthing. Arguments supporting interventionist birthing for all on the basis of equal access to health care must be reviewed.

What is already known on this topic

Women''s preferences for caesarean sections are understood to result from lack of knowledge and psychological aptitude to handle vaginal delivery and its consequencesEfforts to reduce the demand for caesarean sections have focused on providing consumers with correct information on the relative risks associated with vaginal and operative deliveries

What this study adds

In Brazil, many women prefer caesarean sections because they consider it good quality careRich women are more likely to have caesarean sections, supporting the notion that medical intervention represents superior carePoor women may implement a series of medicalised practices that justifies the need for greater medical intervention during birthInterventions for reducing caesarean sections by educating physicians and patients about risk factors associated with birthing procedures are not sufficient
