General practitioners, complementary therapies and evidence-based medicine: the defence of clinical autonomy.

Amidst the substantial change currently gripping primary health care are two developments central to contemporary debate regarding the very nature, territory and identity of general practice - the integration of complementary and alternative medicine (CAM) and the rise of evidence-based medicine (EBM). This paper reports findings from a study based upon 25 in-depth interviews with general practitioners (GPs) personally practising complementary therapies alongside more conventional medicine to treat their NHS patients. The paper outlines the GPs' perceptions of EBM, its relationship to their personal development of CAM, and their notions of good clinical practice more generally. Analysis of the GPs' accounts demonstrates how CAM can be seen as a useful resource with which some GPs defend their clinical autonomy from what they perceive to be the threat of EBM.

Discussions of "code status" on a family practice teaching ward: what barriers do family physicians face?

BACKGROUND: Patients want physicians to ascertain their wishes related to resuscitation, yet such discussions of "code status" are often delayed in the hospital setting, which compromises patient autonomy. Few studies have examined family physicians' views on this topic. Our objectives were to explore the experiences of family physicians and family practice residents in establishing code status with their patients who had been admitted to hospital and to identify barriers to these discussions. METHODS: Semistructured, in-depth interviews were conducted with 5 family physicians and 5 family practice residents admitting patients to a family practice teaching ward in a university-affiliated urban tertiary care hospital. Interview transcripts were analysed inductively, and grounded theory was used to identify conceptual categories and recurring themes. Key findings were validated by means of member checking with participants, consensus meetings of the research team and consultation with qualitative researchers. RESULTS: Barriers to code-status discussions included personal discomfort with confronting mortality, fear of damaging the doctor-patient relationship or harming the patient by raising the topic of death, limited time to establish trust, and difficulty in managing complex family dynamics. In spite of these challenges, family physicians and residents viewed discussions of resuscitation as a significant part of their role. INTERPRETATION: Family physicians and residents need to develop personal awareness about difficulties in confronting mortality, enhance their communication strategies for broaching the topic of code status in the context of a trusting doctor-patient relationship and sharpen their skills in understanding and managing family dynamics related to end-of-life decisions. Awareness of the barriers to code-status discussions can inform research, education and hospital policy. Consultation with patients is needed to develop effective communication strategies.

The first abortion - and the last? A study of the personality factors underlying repeated failure of contraception.

The causes leading to a second abortion were outlined in a psychological study comparing 30 women expecting a second abortion with 29 women who had successfully prevented conception after a first abortion. It was found that both groups improved their contraceptive practices after the first abortion. However, while the latter group continued with their improved practices, the former group went back to the earlier inefficient or non-existent contraceptive behavior. The inability to improve contraception in the long run was not related to differences in educational level or knowledge about contraceptive techniques but to the developmental level of personality structures. The women expecting their second abortion rated lower in control of impulsivity, emotional balance, realism, self-esteem and stability of life as well as capacity for more integrated personal relationships. The differences in personality development and consequently in the capacity for long-term contraception were found to be due to growth conditions in childhood.

The self as a mediator between personality and adjustment.

The self can be conceptualized as a mediating agent that translates personality into situated goal-directed activities and adaptation. This research used a level-of-analysis approach to link personality dimensions (Level I) to self-systems (Level II) and to teacher ratings of adjustment in African American, Mexican American, and European American students (N = 317). The authors hypothesized that links among aspects of self-esteem and teacher ratings of adjustment would be domain specific, and those links to dimensions of the 5-factor model would reflects the domain specificity. Structural equation modeling corroborated hypotheses about domain specificity in links between adjustment and 5-factor dimensions. Results were discussed in terms of levels of analysis for personality structure, personality development, and age-related adaptations to social contexts.

Needs for oral care among people with intellectual disability not in contact with Community Dental Services.

Previous research has found an unmet need for oral care among people with intellectual disability. The key factors which have been indicated are low expectations, fear of treatment, lack of awareness among carers and problems in accessing dental services. The withdrawal of many general dental practitioners (GDPs) from the National Health Service (NHS) may have exacerbated the latter problem in the UK. The aims of the present study were: (1) to assess the extent of unmet clinical needs in a group of adults with intellectual disability living in the community who were not in contact with the Community Dental Service (CDS); and (2) to explore their perceptions of teeth and contact with dentists to identify how oral care can be improved. Interviews were completed with subjects and/or carers and a dental examination was completed. There were higher levels of untreated caries (decay), and gingival or periodontal (gum) problems among the sample than in either the general population, or in a previous survey of CDS users at day centres and residential facilities. The subjects were largely unaware of dental problems, and used the appearance and absence of pain to judge the condition of their teeth. They depended greatly on their carers for decision-making and support with regard to visiting the dentist and tooth-brushing. Carers requested training in oral care and the use of dental services, and support in dealing with clients who have problems tolerating tooth-brushing. The subjects had experienced a wide variation in the treatment provided by dentists, but had not found it difficult to access a dentist despite recent reductions in the availability of NHS dental care. They expressed a particular need for a good relationship with their dentist and for their dentist to have personal skills in relating to people with an intellectual disability. Dental screening checks and oral care training for carers should be made easily available. Care plans should include tooth-brushing and dietary issues for all clients who have their own natural teeth. There are significant training issues for dentists in developing personal skills in total communication, disability awareness and attitudes which value people with intellectual disability.

MR spectroscopy of brain white matter in the prediction of dementia.

BACKGROUND: Previous 1H-MR spectroscopy (MRS) studies compared biochemical spectra of persons with dementia with those of healthy control subjects. Given the long prodromal period of Alzheimer disease (AD), the authors sought to investigate whether biochemical changes can be observed also in the preclinical period. METHODS: The authors prospectively followed 509 elderly persons (ages 60 to 90), who were free of clinical dementia at baseline, for on average 5.9 years. At baseline, 1H-MRS of the brain (1.5 T) was performed in a plane above the lateral ventricles that comprised mainly white matter voxels. Standard ratios of N-acetyl aspartate (NAA), choline (Cho), and creatine (Cr) were calculated. Structural MRI was administered to assess white matter lesions and hippocampal atrophy. All persons were followed for incident dementia through repeated neuropsychological testing and linkage with medical records. RESULTS: During follow-up, 37 persons developed dementia, of whom 27 fulfilled criteria for AD. Overall, biochemical ratios on 1H-MRS at baseline were not associated with the risk of incident dementia. However, people with higher Cho/Cr ratios had a higher risk to develop dementia or AD within 4 years (hazard ratio for dementia per SD increase 1.55 [95% CI 1.05 to 2.28]). This association attenuated and became nonsignificant after adjustment for white matter lesions on MRI. CONCLUSION: These data suggest that there are biochemical changes on 1H-MR spectroscopy of brains of persons with presymptomatic dementia.

[Bacterial pneumonia in HIV-infected patients]

This case-control study assessed risk factors and prognostic indicators of 350 episodes of bacterial pneumonia in 285 HIV-infected patients. On univariate analysis, intravenous drug abuse (p<0.001), regular cigarette smoking (p<0.001), cirrhosis (p=0.04), and history of a previous episode of pneumonia (p=0.04), were risk factors for community-acquired episodes of bacterial pneumonia, whereas length of hospitalization (p=0.01) was a risk factor only for nosocomial bacterial pneumonia. The small amount of circulating T CD4+ cells, (<100/mmc) was a risk factor in both groups of pneumonia (p<0.05). Stepwise logistic regression analysis revealed that IVDA in community-acquired episodes and low levels of circulating T CD4+ cells, both in community-acquired and hospital-acquired episodes, were independent risk factors for the development of bacterial pneumonia. The case-fatality rate observed in our study was 27%. On stepwise logistic regression analysis, T CD4+ cell counts >100/mmc (p<0.02), neutropenia (p=0.04), PO2 arterial level <70 mmHg (p=0.01), and Karnofsky score <50 (p=0.04) were independent indicators of mortality. According to a personally developed prognostic score, 211 episodes of pneumonia (60%) were classified as mild, 63 (18%) as moderate, and 76 (22%) as severe. Clinicians must carefully evaluate those variables that can influence the prognosis of bacterial pneumonia to make early identification of affected patients and to promptly establish the most appropriate therapeutic strategy in each case.

Development of a computerized sexual assessment laboratory.

Computer-assisted psychological assessment has been operational for 25 years. It has been well received by patients and shows a degree of reliability that is comparable to that of conventional testing. The authors report on the development of a computerized psychosexual assessment laboratory in a forensic facility housing convicted sex offenders who volunteered for treatment. The development of the laboratory was in response to the need for uniform psychosocial data on each resident that can be used for making better diagnoses, developing personalized treatment programs, and assessing treatment outcome. The process of selecting the psychological tests and programming them for interactive administration is described, as are the testing procedures using the penile plethysmograph with stimuli based on the Tanner developmental stages. A computer-assisted psychosocial assessment that produces a psychosocial history was developed. The laboratory's overall value in the treatment program is assessed.

[The disabled--object or partner of rehabilitation? (author's transl)].

The experience made in the field of rehabilitation in the post-WW II period have not only led to the enactment of Parliamentary legislation. The personal experiences of rehabilitation workers has often entailed their having gradually formed guiding principles that are being strongly insisted upon in all their dealings with their disabled clients. Rejection of these guidelines may lead to the disabled being regarded as unfit or unwilling, and even more so if he tries to develop personal views on his part in rehabilitation. There is thus a great risk of rehabilitation becoming an end in itself for those who are pursuing it. The disabled for their part should not only underline their rights but accept the responsibilities as well. The risk of stiffening oppositions on all fronts is best countered by those involved talking with each other on a partnership footing. Partnership is however also needed among those who have to co-operate in the various field involved in rehabilitation.

The epidemiology of Helicobacter pylori infection.

The evidence that H. pylori causes gastritis in humans comes from both primary and secondary observations. The most important primary observations are the human volunteer studies, the animal models, and the treatment studies with antimicrobial agents. Supporting information comes from studies showing the specific association of H. pylori infection with type B gastritis and with gastric (but not intestinal) epithelial cells; the specific ultrastructural lesions, including adherence pedestals; the ubiquity and stability of the immune response; the response to bismuth treatment; and the association with epidemic gastritis and hypochlorhydria. It is important to note that all of Koch's postulates have been fulfilled, and despite nearly universal initial skepticism, no evidence exists against the hypothesis that H. pylori plays an etiologic role in type B gastritis. Therefore, it is reasonable to conclude that H. pylori is a pathogen in humans. The known features of H. pylori infection are listed in. Infection is chronic and common throughout the world, with a higher prevalence in developing countries than in developed countries. The prevalence of H. pylori infection increases with age in parallel with that of gastritis. Acquisition of H. pylori infection does not appear to have any seasonality, and infection is equally common among men and women. Without a significant animal or environmental reservoir for human strains of H. pylori, person-to-person contact appears to be the most likely mode of transmission. Exactly how the organism is transmitted from the stomach of one person to that of another remains unclear. Also unknown are the factors which determine who becomes ill after infection; why one person has gastritis alone while another person develops a duodenal ulcer; and how the traditional risk factors for ulcer disease, such as smoking, aspirin, and alcohol, interact with H. pylori infection. Finally, the long term neoplastic consequences of infection must be understood. Further elucidation of the natural history of H. pylori and the consequences of H. pylori infection is the most important goal for future study.

The theory of gender identity disorders.

Experience with more than 500 patients over the last decade has led to the conclusion that the quest for sex reassignment is a symptomatic compromise formation serving defensive and expressive functions. The symptoms are the outgrowth of developmental trauma affecting body ego and archaic sense of self and caused by peculiar symbiotic and separation-individuation phase relationships. The child exists in the pathogenic (and reparative) maternal fantasy in order to repair her body image and to demonstrate the interconvertability of the sexes. Gender identity exists not as a primary phenomenon, but in a sense as a tertiary one. There is, no doubt, a tendency to gender-differentiate in a way concordant with biological endowment. Nevertheless, gender formation is seriously compromised by earlier psychological difficulty. Gender identity is a fundamental acquisition in the developing personality, but it is part of a hierarchical series beginning with archaic body ego, early body image, and primitive selfness, representing their extension into sexual and reproductive spheres. Gender identity consolidates during separation-individuation and gender pathology bears common features with other preoedipal syndromes. Transsexualism is closely linked to perversions, and the clinical syndromes may shade from one into another. However, what is kept at the symbolic level in the perversions must be made concrete in transsexualism. In this regard there is a close relation to psychosis. The clinical complaint of the transsexual is a condensation of remarkable proportions. When the transsexual says that he is a girl trapped in a man's body, he sincerely means what he says. As with other symptoms, however, it takes a long time before he begins to say what he means.

Fathers in the newer family forms: male or female?

Current social trends have produced significant changes in the family system, with the emergence of newer family forms -- single parent and homosexual families. The author used the example of a six year old boy in a female homosexual family to discuss the theories of sex role development. The literature on father-absence and the converging roles of father and mother, men and women, were reviewed with suggestions that women may function as fathers in the newer family forms. Longitudinal studies of children in these newer family forms are needed to define the implications of these social changes for personality development theories and mental health care delivery.

Relation of irrational thinking and the Pessimistic Explanatory Style.

This study investigated the possible relationship between Ellis's construct of irrational thinking and Seligman's construct of explanatory style, with a view toward possibly strengthening the personality theory underlying Rational Emotive Behavior Therapy in particular and cognitive-behavior therapies more generally. In this investigation 180 college students were administered the Survey of Personal Beliefs and the Attributional Style Questionnaire to measure irrational thinking and explanatory style, respectively. Students who scored higher on Pessimistic Explanatory Style also scored higher on Overall Irrational Thinking and on Low Frustration Tolerance than did those who were categorized as having an Optimistic Explanatory Style. This indicates support for Ellis's developing personality theory, especially his theoretical account of depression.

Effect of hepatitis A vaccination schedules on immune response.

An inactivated hepatitis A vaccine was given to 104 seronegative volunteers aged between 19 and 60 years according to two schedules: 0, 1 and 2 months or 0, 1 and 6 months. The vaccine was well tolerated and 97 and 100% of vaccinees developed a serum antibody response following a single and two doses of vaccine respectively. Geometric mean titres increased progressively after each dose; responses following the 0, 1, 6 month schedule were significantly higher at one year but, among those tested at two years, these differences were less marked. Vaccinees, when compared with naturally infected persons, developed poor or undetectable hepatitis-A-virus-specific immunoglobulin G and A antibody responses in saliva and parotid fluid. Such differences are, however, unlikely to affect the protective efficacy of the vaccine.

The participation of children and young people in decisions about UK service development.

BACKGROUND: The involvement of children and young people in decisions regarding service development is well supported in government policy and underpinned by the UN Convention on the Rights of the Child. Information on the extent, nature and outcomes of children and young people's participation can inform further development in this area. METHODS: Systematic literature searches, plus contact with professional networks, were used to gather and review evidence on children and young people's participation. RESULTS: There is a rapidly developing body of information describing and analysing innovative practices in this field. However, there is also a smaller, but substantial, amount of evidence demonstrating the limited extent of current involvement. A good deal of guidance is now available about how to promote the involvement of children and young people. However, the basis of this advice is not always clear, and more evidence about children's views and their experience of participation in public decision-making is required. Issues identified as barriers to change included adult attitudes and intransigence, lack of training for key adults, lack of clarity leading to tokenism, the nature of organizations (i.e. their formality, complexity, bureaucracy and internal politics) and the short-term nature of much funding. The evidence suggests that good practice includes a listening culture among staff, clarity, flexibility, adequate resources, skills development and training for staff and participating children and young people, inclusion of marginalized groups, feedback and evaluation. There is only limited evidence that children and young people's involvement in public decision-making leads to more appropriate services, although there is evidence that participating children and young people benefit in terms of personal development and that staff and organizations learn more about their views. CONCLUSIONS: The value of the participation of children and young people in public decision-making is now well accepted, and is recognized in the standards set in the Children's National Service Framework. However, there is an urgent need for internal and external evaluations of children's involvement.

Obesity among older persons: Screening for risk of adverse outcomes.

A research overview is presented that highlights the growing prevalence of obesity among older persons and the associated risks for medical co-morbidity, healthcare resource use, functional decline and homebound status. Findings reveal that even for obese individuals poor diet quality and micronutrient deficiencies are relatively common concerns. Currently available nutrition risk screening instruments lack validity for overweight / obese older persons. Development and preliminary testing of a new Nutrition Health Outcomes Questionnaire (NHOQ) for this application are presented.

Bacterial pneumonia in HIV-infected patients: analysis of risk factors and prognostic indicators.

This case control study assessed risk factors and prognostic indicators of 350 episodes of bacterial pneumonia in 285 HIV-infected patients. On univariate analysis, intravenous drug abuse (i.v.DA; p < .001 versus controls), regular cigarette smoking (p < .001), cirrhosis (p = .04), and history of a previous episode of pneumonia (p = .04) were risk factors for community-acquired episodes of bacterial pneumonia, whereas length of hospitalization (p = .01) was a risk factor only for nosocomial bacterial pneumonia. The small amount of circulating T CD4+ cells (<100/ mm3) was a risk factor in both groups of pneumonia (p < .05). Stepwise logistic regression analysis revealed that i.v.DA in community-acquired episodes and low levels of circulating T CD4+ cells, both in community-acquired and hospital-acquired episodes, were independent risk factors for the development of bacterial pneumonia. The case-fatality rate observed in our study was 27%. On stepwise logistic regression analysis, T CD4+ cell counts < or = 100/mm3 (p = .02), neutropenia (p = .04), PO2 arterial level < or = 70 mm Hg (p = .01), and Karnofsky score < or = 50 (p = .04) were independent indicators of mortality. According to a personally developed prognostic score, 211 episodes of pneumonia (60%) were classified as mild, 63 (18%) as moderate, and 76 (22%) as severe.

Youth health promotion and health promoting schools: what should be the aims?

The school plays a very important role in health education and promotion at the crucial stage of childhood and adolescence. It develops personal character, skills, attitude and physique, in addition to imparting knowledge. To sustain the concerted effort to address inter-wined social, educational, psychological and health needs of children, training and ongoing reinforcement must be given to teachers. A task force made up of parents, teachers, administrators, students and health professionals must be formed to develop core values, visions, goals and activities; and to provide new direction for health education and promotion. The 'Health Promoting Schools' Programme of the CUHK was launched in 1999 with the aim to promote physical, emotional and intellectual development of students through healthy and hygienic practices. The programme has also conducted researches on health of students, prioritise and evaluate relevant programmes. Recent research studies revealed that students in higher grades had more physical and psychological health problems, probably due to heavy workload and less emphasis on health education in their formal curriculum. Another research study has shown the lack of concrete school policies in health education. It is therefore important to develop policies, practices and structures, as well as regular curricular reviews to promote health of the school children. The "Health Promoting Schools' Programme has already initiated several district based health promotion programmes to pave the way for the formation of local task force on youth health promotion.
