Einstein, race, and the myth of the cultural icon.

The most remarkable aspect of Einstein's 1946 address at Lincoln University is that it has vanished from Einstein's recorded history. Its disappearance into a historical black hole symbolizes what seems to happen in the creation of a cultural icon. It is but one of many political statements by Einstein to have met such a fate, though his civil rights activism is most glaringly missing. One explanation for this historical amnesia is that those who shape our official memories felt that Einstein's "controversial" friends like Paul Robeson and activities like co-chairing the anti-lynching crusade might tarnish Einstein as an icon. That icon, sanctified by Time magazine when it dubbed Einstein "Person of the Century" at the end of 1999, is a myth, albeit a marvelous one. Yet it is not so much the motive for the omission but the consequence of it that should concern us. Americans and the millions of Einstein fans around the world are left unaware that he was an outspoken, passionate, committed antiracist.

The early history of x-ray diagnosis with emphasis on the contributions of physics 1895-1915.

The contribution of physics to the development of x-ray diagnosis was vital in the early years of this century following Röntgen's discovery of x-rays in November 1895. This review records some of the highlights during the period 1895-1915. Much of the information presented has been buried in libraries for more than 50 years and the selection of illustrations and text will be largely unknown to today's readership of Physics in Medicine and Biology. It is also a celebration of what could be achieved in physics before the occurrence of the technological revolution involving not only computer applications but also the disappearance of the small independent x-ray companies into today's multinational companies. Research and development is nowadays just too expensive for much independent practical high-technology contributions without financial backing. Hence this review takes us to those bygone years of experimental physics in home laboratories, poorly equipped university physics laboratories and of the lecture-demonstrations of the period. The sections are presented in a logical order beginning with the discovery of x-rays, followed by x-ray tube technology to the advent of the hot cathode Coolidge tube, with the third and final section covering diagnostic radiology physics. It has been compiled from personal research over 35 years in libraries worldwide, drawing on textbooks, journals, popular magazines, newspapers, x-ray company catalogues and museum exhibits. I have included a certain amount of anecdotal information, because after all, much of the early commentaries were indeed anecdotal--and make very interesting reading. Finally it is commented that although this review is devoted to x-ray diagnosis, x-ray therapy should not be forgotten, and readers are referred to another review by the author on early therapeutic advances.

Psychophysiologic effects of Hatha Yoga on musculoskeletal and cardiopulmonary function: a literature review.

Yoga has become increasingly popular in Western cultures as a means of exercise and fitness training; however, it is still depicted as trendy as evidenced by an April 2001 Time magazine cover story on "The Power of Yoga." There is a need to have yoga better recognized by the health care community as a complement to conventional medical care. Over the last 10 years, a growing number of research studies have shown that the practice of Hatha Yoga can improve strength and flexibility, and may help control such physiological variables as blood pressure, respiration and heart rate, and metabolic rate to improve overall exercise capacity. This review presents a summary of medically substantiated information about the health benefits of yoga for healthy people and for people compromised by musculoskeletal and cardiopulmonary disease.

Media coverage of women's health issues: is there a bias in the reporting of an association between hormone replacement therapy and breast cancer?

Media coverage of scientific research plays a major role in shaping public opinion and influencing medical practice. When an association is controversial, such as with hormone replacement therapy (HRT) and breast cancer, it is important that a balanced picture of the scientific literature be reported. The objective of this study was to assess whether scientific publications that do and do not support an HRT/breast cancer association were cited in the media in proportions similar to those with which they appear in the scientific literature. Scientific publications reporting on the HRT/breast cancer association published from January 1, 1995, to June 30, 2000, were identified through a systematic Medline search. Media reports from newspapers, magazines, television, and radio that reported on HRT and breast cancer were retrieved from an online database. Investigators independently recorded characteristics of the scientific publications and media reports. A total of 32 scientific publications were identified: 20 (62.5%) concluded there was an increased risk of breast cancer associated with HRT (positive publications), and 12 (37.5%) concluded there was no evidence for an association (null publications). Nearly half (47%) of the scientific publications were not cited by the media. There were 203 media citations of scientific publications: 82% were of positive publications and 18% were of null publications, representing a significant excess of citations of positive publications (p < 0.01). Media coverage of this controversial issue is based on a limited sample of the scientific publications. Moreover, the excess of media citations for positive scientific publications suggests a bias against null scientific publications.

Alternative medicine in Vermont--a census of practitioners: prevalence, patterns of use, and national projections.

The number of alternative/holistic practitioners in Vermont was estimated by two methods: scanning advertisements (yellow pages, newspaper and magazine ads, brochures), and by word-of-mouth canvassing. We located 897 Vermonters who derive most of their annual income practicing at least 1 of 97 different types of alternative medicine and therapy. Most practitioners were female and most practiced more than one type of healing. Bodyworkers were the most prevalent practitioners, followed by chiropractors, acupuncturists, herbalists, and holistic psychotherapists. On a per-capita basis, there is 1 alternative practitioner per 652 Vermonters (or 153 practitioners per 100,000 population). This census nearly equals that of Vermont's M.D. population. Extrapolating this Vermont census to a nationwide estimate of alternative practitioners suggests there are over 403,000 full-time alternative/holistic healers practicing in the United States.

Therapeutic benefits of qigong exercises in combination with drugs.

This article reviews clinical studies from the Qigong Bibliographic Database, developed by the Qigong Institute, a nonprofit organization. This database was started in 1994 and holds approximately 1300 references going back to 1986, covering medical applications, scientific, and experimental studies on qigong from China, the United States, and Europe. Records in English have been compiled from International Qigong conferences and seminars, scientific journals, magazines, dissertations, MEDLINE, and other databases. The therapeutic role of qigong exercises combined with drugs is reported for three medical conditions that require drug therapy for health maintenance: hypertension, respiratory disease, and cancer. In these studies, drugs were administered to all patients who were divided into two groups, a group that practiced qigong exercises and a control group that did not. Taken together, these studies suggest that practicing qigong exercises may favorably affect many functions of the body, permit reduction of the dosage of drugs required for health maintenance, and provide greater health benefits than the use of drug therapy alone. For hypertensive patients, combining qigong practice with drug therapy for hypertensive patients resulted in reduced incidence of stroke and mortality and reduced dosage of drugs required for blood pressure maintenance. For asthma patients, the combination therapy permitted reduction in drug dosage, the need for sick leave, duration of hospitalization, and costs of therapy. For cancer patients, the combination therapy reduced the side effects of cancer therapy. Also reported is a study showing that the practice of qigong helps to rehabilitate drug addicts. The reported studies do not necessarily measure up to the strict protocols required for randomized controlled clinical trials.

Women's knowledge about menopause, hormone replacement therapy (HRT), and interactions with healthcare providers: an exploratory study.

This community mail-based survey received responses from 665 women to questions in three areas: (1) sources of information about menopause, (2) knowledge of health risks associated with menopause, and (3) knowledge about hormone replacement therapy (HRT). Women received information from many sources, including healthcare providers, friends, and mothers, but the number one source of information about menopause was women's magazines (76%). Over half of women surveyed said they had left healthcare appointments with unanswered questions about menopause and HRT. Although women seemed to have a basic understanding of the symptoms of menopause, their knowledge of the long-term health risks affected by menopause was poor. For example, women were much more likely (60%) to know that osteoporosis risk increased with menopause than to know that heart disease risk increased (30%) despite the much higher prevalence and severity of heart disease as a health problem of menopausal women. Many women thought that menopause itself (independent of aging) increased the risk of breast cancer. This finding may help explain the low percentage of women who take HRT for menopause despite proven health benefits. It is clear that better education about menopause needs to be accomplished regarding the long-term risk associated with menopause and the pros and cons of HRT. Strategies for improving education and interactions with healthcare providers are suggested.

Quality of life after open-heart surgery in patients over 75 years old.

In a postal study we used the Nottingham Health Profile questionnaire to assess the quality of life of elderly survivors of open-heart surgery. From January 1984 to October 1993, 146 patients over 75 years of age underwent open-heart surgery in the Department of Cardiovascular Surgery at Beasançon (France). Eleven patients (7. 5%) died in the immediate post-operative course. Patients' mean follow-up was 3.4 +/- 2.4 years. Fourteen patients died during follow-up. One hundred and four completed Nottingham Health Profile questionnaires were returned. Five per cent of the patients lived in an old people's home. Six per cent of the patients were unable to walk at all. One patient out of five felt isolated. Fifteen per cent of the patients were in constant pain. Half of the patients took sleeping pills. Conversely, 87% of the patients felt an improvement after surgery. Sixty-two per cent continued to drive. Ninety-seven patients (92%) did at least one of the following three activities: watched television, listened to the radio, read books or magazines. Fifty-eight patients (56%) walked on a regular basis. The different types of pathology, of surgical procedures and whether or not a pacemaker was implanted during the post-operative course were not reflected in the quality of life (QOL) scores. After cardiac surgery, most of the patients were physically autonomous and related to their exterior world.

The Pap smear, automated rescreening, and negligent nondisclosure.

A new element in the Papanicolaou smear liability crisis is the recent US Food and Drug Administration approval of 2 automated rescreening devices. Their manufacturers have undertaken aggressive advertising in medical journals and in women's magazines, generating controversy about whether this positions such devices as the new standard of care and whether failure to offer such rescreening might lead to liability alleging to tort of negligent nondisclosure, with contributing opinions from pathologists' and manufacturers' counsels. Cases are cited in prenatal diagnostics and blood banking that established liability for failing to disclose diagnostic modalities used by at most only a minority of practitioners and, therefore, have not yet achieved standard-of-care status. It is concluded that informed consent for cervicovaginal smears should include disclosure of the availability of automated rescreening to reduce negligence liability.

Mixed feelings: satisfaction and disillusionment among Australian GPs.

BACKGROUND AND AIMS: Medical practitioners' satisfaction with their work impacts on quality of care for their patients and on their own sense of fulfillment. Reforms introduced in the early 1990s into Australian general practice have led to concerns over the morale of GPs. This study examines satisfaction and dissatisfaction of GPs with regard to the reform strategy. METHOD: GPs throughout Australia were approached via a popular GP magazine to express their views in a questionnaire comprising closed-end and open-ended questions enquiring about satisfaction with their current role and sources of satisfaction (and dissatisfaction) of working in general practice. Factor analysis was used to identify different sources of satisfaction (and dissatisfaction), which were intercorrelated and which together represented underlying factors. Logistic regression modelling was used to determine which sources were most strongly associated with being satisfied (or not satisfied), and to explore GP characteristics associated with satisfaction. RESULTS: A total of 2186 questionnaires were returned, representing the opinions of 14-18% of Australian GPs. Two-thirds (68%) of respondents reported being satisfied, most frequently with the variety of work and establishing relationships with patients and their families. Six satisfaction factors were identified on factor analysis, the most important characterizing social and interpersonal roles. Leading sources of dissatisfaction related to perceived interference by the government. Six dissatisfaction factors were identified on factor analysis, the most important characterizing governmental issues. However, on logistic regression other sources of dissatisfaction (reflecting disillusionment) were most strongly associated with not being satisfied. CONCLUSIONS: The main sources of satisfaction are those which typify the long-term caring role of the community GP. While the reform strategy aimed to address problems with the organization and financing of general practice, the resulting intervention is the focus of dissatisfaction. Among dissatisfied GPs these attitudes may arise primarily from a sense of disillusionment.

Self-medication among secondary school pupils in Hong Kong: a descriptive study.

A self-completion questionnaire was used to survey self-medication among secondary school pupils in Hong Kong. Data were collected from 4793 pupils aged 10 to 23 years (55.9% female and 44.1% male). Nearly three quarters (72.1%) had taken self-medication without consulting a medical practitioner and 51.8% of the sample had done so without the knowledge of older family members. The prevalence of self-medication increased with age. More than half the pupils (50.4%) indicated that trivial illness did not warrant a consultation with a doctor. Information relating to the sources of self-administered drugs, types of drugs used and sources of information about these drugs was collected. Medicine cabinets at home and pharmacy shops were the two most common places from which the pupils obtained their drugs. Though the prevalence of taking tranquillizers and sleeping tablets was found to be low, the probability of young people, especially boys, obtaining dangerous drugs from these places should not be overlooked. The medical, nursing and teaching professions should take a more active role in health education, as the sources from which the pupils obtained their drug knowledge, in descending order of frequency, were: family members, previous illness experience, pharmacy shops, doctor or nurse, television or radio, newspapers or magazines, friends and teachers.

Balancing breastfeeding and paid employment: a project targeting employers, women and workplaces.

Since breastfeeding is acknowledged as the best nutrition for young babies, it needs to be protected, supported and promoted. This includes enabling mothers to continue breastfeeding even when they return to work. This paper describes a project that promotes balancing breastfeeding and paid work through the development, distribution, promotion and evaluation of suitable materials to workplaces, employers and women in Australia. Information provided in a workplace kit was based on previous successful strategies from published works in refereed journals and in consultation with employers, employees and other key people. Information for employees was further summarized and translated into Arabic, Chinese, Turkish, Spanish and Vietnamese. Over 50,000 information kits were distributed Australia-wide using a database that comprised contact details of medium to large workplaces plus employee and employer organizations, with preference given to workplaces that employed women of childbearing age and women from diverse cultural backgrounds. The translated material was also distributed to migrant resource centres and working women's centres around Australia. Promotion of the project was extensive, resulting in 20 newspaper articles, 17 radio interviews or news items, and articles in 18 newsletters and professional journals and three magazines. The project was also promoted at three conferences and one seminar. Evaluation (directed at employers) focused primarily on the distribution and content of the information kit, since the evaluation was conducted soon after distribution. The evaluation survey was sent to 1571 valid contacts (808 e-mail addresses, 1360 fax numbers). The response rate was 12.8% (n = 202). Seventy per cent of responding businesses rated the information kit as excellent. Over half anticipated the kit would be useful in their organization, while over two-thirds agreed that the kit provided sufficient information and suitable solutions to support balancing breastfeeding and work in their organization. While this project has achieved its objectives, further work is required to assist organizations to develop and implement policies and procedures for balancing breastfeeding and work, so that breastfeeding mothers who are returning to work can continue to breastfeed as long as they and their baby require it.

Evaluation of a national programme to reduce inappropriate use of antibiotics for upper respiratory tract infections: effects on consumer awareness, beliefs, attitudes and behaviour in Australia.

The over-use of antibiotics, in particular, inappropriate use to treat upper respiratory tract infections (URTIs), is a global public health concern. In an attempt to reduce inappropriate use of antibiotics for URTIs, and, in particular, to modify patient misconceptions about the effectiveness of antibiotics for URTIs, Australia's National Prescribing Service Ltd (NPS) has undertaken a comprehensive, multistrategic programme for health professionals and the community. Targeted strategies for the community, via the NPS common colds community campaign, commenced in 2000 and have been repeated annually during the winter months. Community strategies were closely integrated, using the same tagline, key messages and visual images, and were delivered in numerous settings including general practice, community pharmacy, child-care centres and community groups. Strategies included written information via newsletters and brochures, mass media activity using billboards, television, radio and magazines and small grants to promote local community education. The evaluation used multiple methods and data sources to measure process, impact and outcomes. Consistent with intervention messages, the integrated nationwide prescriber and consumer programme is associated with modest but consistent positive changes in consumer awareness, beliefs, attitudes and behaviour to the appropriate use of antibiotics for URTIs. These positive changes among the community are corroborated by a national decline in total antibiotic prescriptions dispensed in the community (from 23.08 million prescriptions in 1998-99 to 21.44 million in 2001-02) and, specifically, by a decline among the nine antibiotics commonly used for URTI such that by 2003 nationally 216,000 fewer prescriptions for URTI are written each year by general practitioners.

How adolescent girls interpret weight-loss advertising.

While they demonstrate some ability to critically analyze the more obvious forms of deceptive weight-loss advertising, many girls do not recognize how advertising evokes emotional responses or how visual and narrative techniques are used to increase identification in weight-loss advertising. This study examined how girls aged 9-17 years interpreted magazine advertising, television (TV) advertising and infomercials for weight-loss products in order to determine whether deceptive advertising techniques were recognized and to assess pre-existing media-literacy skills. A total of 42 participants were interviewed in seven geographic regions of the United States. In groups of three, participants were shown seven print and TV advertisements (ads) for weight-loss products and asked to share their interpretations of each ad. Common factors in girls' interpretation of weight-loss advertising included responding to texts emotionally by identifying with characters; comparing and contrasting persuasive messages with real-life experiences with family members; using prior knowledge about nutrition management and recognizing obvious deceptive claims like 'rapid' or 'permanent' weight loss. Girls were less able to demonstrate skills including recognizing persuasive construction strategies including message purpose, target audience and subtext and awareness of economic factors including financial motives, credibility enhancement and branding.

Barriers to social support and support received from their families of origin among gay men with HIV/AIDS.

The study discussed in this article examined the barriers to obtaining social support and the support received from the family of origin among gay men with HIV/AIDS. The survey was distributed through 21 social service agencies in the Midwest and advertised in two Midwestern newspapers and two national magazines; the result was a sample of 117 gay men with HIV/AIDS. The family provided emotional support and fun relaxation at significantly higher levels than informational and instrumental support. Mothers and siblings provided a significantly higher level of support than fathers. The highest level of barrier to obtaining support was experienced in relation to the family's lack of knowledge regarding HIV/AIDS, and fears of compromising independence. Implications for practice are discussed.

Increasing geographical distribution and density of Ixodes ricinus (Acari: Ixodidae) in central and northern Sweden.

The geographical distribution and density of Ixodes ricinus (L.) in the 2 northern regions, Svealand and Norrland, in Sweden were studied by using a questionnaire in Swedish magazines for house owners and dog owners, and in provincial newspapers. Analysis of the approximately 1,200 answers revealed that ticks are present in all parts of Svealand (except northern Värmland and northern and western Dalarna), the southeastern part of Norrland (i.e., Gästrikland and Hälsingland), and along the Baltic Sea coast of central and northern Norrland. The proportion of answers reporting ticks and the estimated tick density (i.e., the number of ticks infesting dogs and cats) decreased from south to north. The answers to the questionnaire and data from field sampling of ticks suggest that tick density decreased distinctly along a narrow boundary zone, coinciding with the biological limit of Norrland (Limes Norrlandicus), crossing Sweden through southern Värmland, southeastern Dalarna, and central Gästrikland. The results of the questionnaire suggest that I. ricinus ticks are more widespread today than in the early 1980s, especially in Värmland, western and central Dalarna, Hälsingland, and the coastal areas of Medelpad, Angermanland, and Västerbotten, and that the proportion of the human population at risk for tick-borne pathogens in Svealand and Norrland is increasing.

One face of beauty, one picture of health: the hidden aesthetic of medical practice.

Unrecognized presuppositions about patient appearance have become increasingly important in medicine, medical ethics and medical law. Symptoms of these historically conditioned assumptions include common ageism, aesthetic surgery, and litigation about 'wrongful life'. These phenomena suggest a societal intolerance for what is considered an 'abnormal' appearance. Among others, eighteenth-century artists and anatomists helped to set these twentieth-century precedents, actually measuring deviations of external traits to analogous deformations of the soul, and drawing moral conclusions from physiognomic measurements. Other eighteenth-century artists countered with pathognomy, recognizing that uneven physical features may indicate humanity, instead of character flaws. We suggest that there is an important and as yet unrecognized role played by visual and perceptual preferences in our judgments concerning normalcy and anomaly. We further suggest a shift away from our current fashion-magazine, youth-oriented aesthetic, and towards an aesthetic of imperfection. Physicians and medical students can be made aware of their historically conditioned reactions to 'abnormal' appearing patients by studying the understandings and methods with which artists have portrayed those who are considered deformed in appearance.

Environmental influences: factors influencing a woman's decision to use dietary supplements.

Use of dietary supplements by women, particularly those over 40 years of age may be widespread in the United Kingdom. However, from surveillance data, there appears to be a disparity between nutrition and health needs and the rationale for and actual use of dietary supplements by women. This apparent paradox forms the basis for an inverse supplement hypothesis (i.e., supplement use in women appears to be most prevalent among those with least need). Little research has been done to examine the factors underlying the decision to use dietary supplements. Reasons for consuming dietary supplements are often complex, combining social, psychological, knowledge and economic factors. The theory of planned behavior is a widely used model for assessing factors influencing behavioral motivation and action that may be useful for assessing specific diet- and nutrition-related practices. It provided the basis for the development of a questionnaire to explore overall dietary supplement use in a cohort of women in the United Kingdom. The analysis of factors related to beliefs underlying dietary supplement use revealed differences between supplement users and nonusers. Differences included a stronger belief by users than nonusers that taking dietary supplements ensures against possible ill health. Both users and nonusers of supplements also perceived the media (books and magazines) to be a powerful influence on a person's decision to use supplements. These findings highlight the potential of the theory of planned behavior in exploring supplement-taking behavior while throwing light on the factors influencing an individual's motivations to use dietary supplements.
