The discovery of RNA interference (RNAi), an endogenous cellular gene-silencing mechanism, has already provided a powerful tool for basic science researchers to study gene function. The subsequent finding that RNAi also operates in mammalian cells has generated excitement regarding potential therapeutic applications. In this article we discuss the basic mechanism of RNAi and the therapeutic opportunities and obstacles for harnessing RNAi for therapy of human disease.

The use of complementary and alternative medicine (CAM) has grown dramatically in recent years, as has research on the safety and efficacy of CAM treatments. Minimal attention, however, has been devoted to the ethical issues relating to research on CAM. We argue that public health and safety demand rigorous research evaluating CAM therapies, research on CAM should adhere to the same ethical requirements for all clinical research, and randomized, placebo-controlled clinical trials should be used for assessing the efficacy of CAM treatments whenever feasible and ethically justifiable. In addition, we explore the legitimacy of providing CAM and conventional therapies that have been demonstrated to be effective only by virtue of the placebo effect.

The chronic care model is a guide to higher-quality chronic illness management within primary care. The model predicts that improvement in its 6 interrelated components—self-management support, clinical information systems, delivery system redesign, decision support, health care organization, and community resources—can produce system reform in which informed, activated patients interact with prepared, proactive practice teams. Case studies are provided describing how components of the chronic care model have been implemented in the primary care practices of 4 health care organizations.

Pain is a complex clinical problem. Assessment depends on verbal report, and the patient's physical perceptions may be modified by cognitive and affective factors. The salience of pain as a problem in its own right has grown since 1945 and new therapeutic alternatives have developed from research and from new theoretical perspectives. This short historical review of the highlights of the history of pain management gives particular emphasis to the 20th century and to chronic and cancer pain.

Researchers, clinicians, and policy makers face 3 challenges in writing about race and ethnicity: accounting for the limitations of race/ethnicity data; distinguishing between race/ethnicity as a risk factor or as a risk marker; and finding a way to write about race/ethnicity that does not stigmatize and does not imply a we/they dichotomy between health professionals and populations of color. Josurnals play an important role in setting standards for research and policy literature. The authors outline guidelines that might be used when race and ethnicity are addressed in biomedical publications.

Although the present era offers more promise for medical research progress than ever before, academic medical centers also face more daunting challenges for the conduct of medical research: high expectations by the public for a steady stream of lifesaving discoveries, news about financial conflicts of interest and scientific misconduct by researchers that threatens to erode public trust in academic institutions, tensions between the cultural norms of academe and industry that cloud their growing partnerships, obstacles to recruiting and retaining physician-scientists, constrained funding sources and increasing costs of research, and the need to transform the academic reward structure and culture to encourage collaboration and adapt to the new "team science." The interconnectedness of these challenges magnifies their difficulties and importance. Maintaining academic medicine’s integrity and effectiveness in pursuing its vital research mission will be a crucial challenge for medical schools and teaching hospitals in the years ahead.

This article—the first in a series on primary care—outlines the daunting challenges facing primary care today. Most people in the United States desire a primary care "home" to provide for and coordinate their health care needs. Yet primary care is endangered by physician stress, inadequate performance in managing chronic illness, and inability to provide prompt access and reliable continuity of care. Fundamental redesign is needed to improve access to and quality of care while easing physicians' workload without causing major increases in health care costs.

The aim of medical research is to advance scientific knowledge and hence—directly or indirectly—lead to improvements in the treatment and prevention of disease. Each research project should continue systematically from previous research and feed into future research. Each project should contribute beneficially to a slowly evolving body of research. A study should not mislead; otherwise it could adversely affect clinical practice and future research. In 1994 I observed that research papers commonly contain methodological errors, report results selectively, and draw unjustified conclusions. Here I revisit the topic and suggest how journal editors can help.

The concept of manipulation of the vascular bed to either increase or decrease the number of blood vessels has attracted considerable interest. This review focuses on angiogenesis as a therapeutic target, particularly in the context of cancer and arthritis, as well as on promoting angiogenesis in cardiovascular disease and the healing of bone fractures. Although once touted almost as a panacea for treatment of tumors, as well as other diseases associated with angiogenesis, such as diabetic retinopathy or rheumatoid arthritis, it is now clear that such enthusiasm was somewhat premature. Similarly, some clinical trials of therapeutic angiogenesis for the management of cardiovascular disease have been disappointing. Nevertheless, this exciting field of research holds promise for more targeted therapies.

The National Institute for Health and Clinical Excellence (NICE) was established as a part of the British National Health Service in 1999 to set standards for the adoption of new health care technologies and the management of specific conditions. In doing so it was required explicitly to take into account both clinical effectiveness and cost-effectiveness. This article describes how NICE has responded to the challenge and considers whether its experience of balancing quality, innovation, and value for money holds policy lessons for the United States.

Since family practice was first recognized as a specialty in the late 1960s, considerable intellectual and organizational change has occurred in medicine, especially during the 1990s. To reflect on and reconsider the role of family practice in US health care, this article reviews the development of family practice as a specialty, provides a current assessment of the status of family medicine in the United States, and comments on issues that are of ongoing importance to family practice.

This article reviews research evidence showing to what extent the chronic care model can improve the management of chronic conditions (using diabetes as an example) and reduce health care costs. Thirty-two of 39 studies found that interventions based on chronic care model components improved at least 1 process or outcome measure for diabetic patients. Regarding whether chronic care model interventions can reduce costs, 18 of 27 studies concerned with 3 examples of chronic conditions (congestive heart failure, asthma, and diabetes) demonstrated reduced health care costs or lower use of health care services. Even though the chronic care model has the potential to improve care and reduce costs, several obstacles hinder its widespread adoption.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic form of renal phosphate wasting that results in severe hypophosphatemia, a defect in vitamin D metabolism, and osteomalacia. This debilitating disorder is illustrated by the clinical presentation of a 55-year-old woman with progressive fatigue, weakness, and muscle and bone pain with fractures. After a protracted clinical course and extensive laboratory evaluation, tumor-induced osteomalacia was identified as the basis of her clinical presentation. In this article, the distinctive clinical characteristics of this syndrome, the advances in diagnosis of TIO, and new insights into the pathophysiology of this disorder are discussed.

Molecular imaging is an emerging field that aims to integrate patient-specific and disease-specific molecular information with traditional anatomical imaging readouts. The information provided by this field may ultimately allow for noninvasive or minimally invasive molecular diagnostic capabilities, better clinical risk stratification, more optimal selection of disease therapy, and improved assessment of treatment efficacy. In this update, we first provide an overview of clinically relevant molecular imaging technologies and imaging agents. Next, their applications to disease detection, drug discovery, and biomedical research are discussed. To specifically demonstrate the potential of molecular imaging, we highlight recent advances in clinical and preclinical molecular imaging of cancer and atherosclerosis.

Many 21st-century observers explain international efforts to control infectious diseases as a function of globalization and recent transformations in international commerce, transportation, and human migration. However, these contemporary global health initiatives can be more fully understood by also exploring the origins of international health organizations and regulations, which were initially dedicated exclusively to stemming the tide of infectious epidemics. This article reviews 3 eras of international approaches to controlling infectious diseases (1851-1881, 1881-1945, and 1945 to the present) and concludes by assessing how nations have a strong fiscal and humanitarian incentive to invest in infectious disease control programs and infrastructures in and beyond their own borders.

In the United States, more than 2 million children and adolescents (3.4%) younger than 18 years have experienced the death of a parent. When death can be anticipated, as with a terminal illness, and even when the death is sudden, as in the September 11, 2001, attacks on the World Trade Center and Pentagon, physicians and other health care professionals have an opportunity to ameliorate the impact of the loss. Developmental factors shape adolescents' reactions and responses to the death of a parent. Recent research in childhood and adolescent bereavement shows how health professionals can support the adolescent's coping strategies and prepare the family to facilitate an adolescent's mastery of adaptive tasks posed by the terminal phase of the parent's illness, the death, and its aftermath. Robert, a bereaved 14-year-old, illustrates some of these adaptive challenges.

Because of the traditional subordination of education to service, graduate medical education (GME) in the United States has never realized its full educational potential. This article suggests 4 strategies for reasserting the primacy of education in GME: limit the number of patients house officers manage at one time, relieve the resident staff of noneducational chores, improve educational content, and ease emotional stresses. Achieving these goals will require regulatory reform, adequate funding, and institutional competency in the use of educational resources. Modern medicine grows ever more complex. The need to address the deficiencies of GME is urgent.

ABSTRACT
Polyarteritis nodosa (PAN) is regarded rightly as the grandfather of the vasculitides. In this Grand Rounds, the case of a 30-year-old man with a 12-year illness is described. The patient presented with daily fevers, tachycardia, and cutaneous ulcers on his distal extremities. He eventually developed mononeuritis multiplex. Because of the striking pattern of his fevers, he was diagnosed for many years as having adult-onset Still disease. Following the addition of daily cyclophosphamide to his long-standing regimen of prednisone, the patient's disease entered remission for the first time in more than a decade. He was ultimately able to discontinue all of his immunosuppressive medications. The case is discussed in the context of the first patient ever described with PAN, the classic report of Kussmaul and Maier.

The growth of specialization in graduate medical education (GME) and physician practice continues at a rapid rate, generating increasing national attention. Although the major educational, accrediting, and certifying bodies have mechanisms for approving new areas of study and practice, the results of their efforts have not been consistently congruent. This article presents information about GME since the beginnings of its standardization and accreditation in the early 20th century, its growth during and following World War II, and the variations among accredited specialties and subspecialties, certificates, and self-designated practice areas that have resulted from this long period of unstructured growth.

Physicians increasingly face conflicts between the ethic of undivided loyalty to patients and pressure to use clinical methods and judgment for social purposes and on behalf of third parties. The principal legal and ethical paradigms by which these conflicts are managed are inadequate, because they either deny or unsuccessfully finesse the reality of contradiction between fidelity to patients and society's other expectations of medicine. This reality needs to be more squarely acknowledged. The challenge for ethics and law is not to resolve this tension—an impossible task—but to mediate it in myriad clinical circumstances in a way that preserves the primacy of keeping faith with patients while conceding the legitimacy of society's other expectations of medicine.
