Developing a virtual interdisciplinary research community in higher education.
As multidisciplinary collaboration in both clinical and research settings is becoming a key aspect of contemporary health care, strategies to enhance interprofessional interaction in postgraduate research programmes can offer important experiences to facilitate ongoing interprofessional relationships. This paper provides a retrospective appraisal of a strategy which used computer-mediated communication to develop a virtual community network, known as'health_voice' accessed through a web page. The rationale for developing the network is presented, and the process of designing and establishing the web-site through an action research approach is described The outcome of the strategy is reviewed with regard to the relationships between the real' and 'virtual' community. Reflections on the developmental process contextualise the initiative within a concept of a community-of-practice. It is acknowledged that the use of a virtual arena for communication within a research community involves a cultural change in the dynamics of higher degree teaching and learning. Future plans to further embed the virtual environment within a postgraduate research culture are given.

The Measles Laboratory Network in the region of the Americas.
The success of measles eradication depends upon a laboratory network to rapidly analyze samples obtained as part of surveillance and case investigation. The Pan American Measles Laboratory Network was established in 1995. Major activities of the 22 participating laboratories include the rapid testing of serum samples to diagnose measles, analysis and recommendation of techniques to be used in serologic testing, training in virus isolation, and procurement and distribution of laboratory materials. In addition, a comprehensive quality-control program and an electronic communication network have been developed. Testing for rubella has also been incorporated. The Network has been crucial to the great progress made toward eradicating measles from the Western Hemisphere. The priority given to the laboratories in the Network must continue in order to ensure that the eradication goal is reached and that validation of the interruption of endemic transmission of measles is documented.

Paralytic poliomyelitis can be eliminated.
Since the introduction and widespread use of inactivated and oral poliovirus vaccines, there has been a continued and increasing commitment to worldwide poliomyelitis control. The eradication of poliomyelitis in certain countries, smallpox eradication worldwide, the World Health Organization's (WHO) Expanded Programme on Immunization, and advances in poliovirus vaccine production augur well for worldwide elimination within the next few decades. The success of any such program rests firmly upon scientific feasibility, intensive epidemiologic surveillance, and economic justification. The development of a variety of disease-specific control/prevention programs worldwide have improved communicable disease reporting in many countries and established health-care infrastructure as well. Equally important has been the emergence of the concept of epidemiologic surveillance. The success of poliomyelitis elimination in large parts of the world, the WHO commitment, and the tragic, visible effects of poliomyelitis are sufficiently strong arguments to persuade the countries of the world to make the necessary effort to eliminate poliomyelitis within the next generation.

The performance of social marketing in reaching the poor and vulnerable in AIDS control programmes.
The article reviews evidence on the impact and effectiveness of condom social marketing programmes (CSMPs) in reaching the poor and vulnerable with information, services and products in the context of HIV/AIDS/STD prevention and control. Ideally, the success of CSMPs would be judged by whether they contribute to sustained improvements in sexual health outcomes at the population level. Given methodological and attribution difficulties, intermediary criteria are employed to assess effectiveness and impact, focusing on changes in behaviour (including condom use) among poor and vulnerable groups, and access by the poor and vulnerable to condoms, services and information. It remains difficult to reach definitive conclusions about the extent to which CSMPs meet the sexual health needs of the poor and vulnerable, due largely to reliance on sales data for CSMP monitoring and evaluation. CSMPs (like many health programme strategies) have traditionally collected little information on client profiles, health-seeking behaviour, condom use effectiveness, and supply-side issues. Recent data indicate that CSMPs are unlikely to be pro-poor in their early stages, in terms of the distribution of benefits, but as CSMPs mature, then inequities in access diminish, followed by reduced inequities in condom use. The paper assesses the extent to which social marketing is effective in improving access for the poor and vulnerable using a number of variables. In terms of economic access, it is evident that low-income groups are particularly sensitive to CSMP price increases, and that a cost-recovery focus excludes the poorest. Convenience is significantly improved for those who can afford to pay, and CSMPs appear to be addressing social and regulatory constraints to access. Conventional CSMP monitoring systems make it difficult to assess the effectiveness of behavioural change IEC strategies, although data on this dimension of the social marketing approach are beginning to emerge.

Prevention and control of iron deficiency: priorities and action steps.
The strengthening of global efforts to prevent and control iron deficiency requires priority setting and action steps in several key areas, including research, partnership formation, policy setting and the integration of intervention strategies. Research priorities include the development of improved assessment tools, evaluation of fortification strategies, improvement in interventions for infants, evaluation of combined intervention strategies to address multiple micronutrients and development and testing of interventions using genetically engineered foods with improved nutritional qualities. Policy priorities include the expansion of partnerships, balancing of advocacy, research and program implementation, and improved communications. Priorities in partnership formation include building strong linkages between public sector efforts and the food industry to enhance training, technical expertise and advocacy. Strategies to address iron deficiency should seek to integrate efforts in food fortification, supplementation, dietary improvement and complementary public health measures.

Enhancing staff development with a structured preceptor program.
The unexpected expansion of a 14-bed medical intensive care unit exposed the need for a structured preceptor/orientation program. Staff feedback and a review of quality indicators further substantiated this finding and revealed a decrease in standards of practice and problems in staff development. A restructured preceptor/orientation program yielded improvements in communication and staff satisfaction. Preceptors and orientees now have a better understanding of their roles and expectations, and quality of care is improving in an environment that promotes personal and professional growth.

The role of nonphysician consultants as health-care educators in postgraduate programs of anesthesiology.
Many physicians believe that the tasks of postgraduate medical education and faculty development are best carried out by senior physicians trained in the appropriate specialty. However, many also will admit that, as physicians, they have received too little training for such an educational role, and that the practical demands of medical practice, scientific research, and administration make it difficult if not impossible to allocate time to continuing medical education program development, curriculum design for residency training, teacher training, and other key aspects of postgraduate medical education. Many medical disciplines have attempted to alleviate this problem by using nonphysician health-care educational consultants in their training programs. However, little attention has been paid to the possibilities of using such consultants in anesthesiology residency education and faculty development. Such consultants in postgraduate medical education and training programs in anesthesiology could perform a wide variety of functions and roles because they possess skills and technical expertise in teaching, training, curriculum design, evaluation, program planning, and interpersonal communications that faculty members often lack. The successful use of a nonphysician consultant in the Department of Anesthesiology at Hahnemann University in Philadelphia, Pennsylvania, is described.

Best practices for inclusive child and adolescent out-of-school care: a review of the literature.
Inclusion or full participation by children with disabilities in programs and activities designed for typically developing children benefits children with and without disabilities and their families. Inclusive care programs are least available for school-age children and adolescents. A review of the literature identified best practices for effective inclusive out-of-school care, including: a written program philosophy; a written plan for inclusive programs; strong leadership; a disability awareness program for staff and children; training and support for staff; sufficient staff to meet program needs; a working communication and collaboration; an adapted setting, activities, and time parameters; proficient collaboration with families; and an evaluation plan.

Experience with a routine fecal sampling program for plutonium workers.
A quarterly fecal sampling program was conducted at the U. S. Department of Energy's Hanford site for congruent to 100 workers at risk for an intake of plutonium oxide and other forms of plutonium. To our surprise, we discovered that essentially all of the workers were excreting detectable activities of plutonium. Further investigation showed that the source was frequent, intermittent intakes at levels below detectability by normal workplace monitoring, indicating the extraordinary sensitivity of fecal sampling. However, the experience of this study also indicated that the increased sensitivity of routine fecal sampling relative to more common bioassay methods is offset by many problems. These include poor worker cooperation; difficulty in distinguishing low-level chronic intakes from a more significant, acute intake; difficulty in eliminating interference from ingested plutonium; and difficulty in interpreting what a single void means in terms of 24-h excretion. Recommendations for a routine fecal program include providing good communication to workers and management about reasons and logistics of fecal sampling prior to starting, using annual (instead of quarterly) fecal sampling for class Y plutonium, collecting samples after workers have been away from plutonium exposure for a least 3 d, and giving serious consideration to improving urinalysis sensitivity rather than going to routine fecal sampling.

The effect of self-care interventions on the use of medical service within a Medicare population.
To determine the effect of a self-care communication-based health education program on ambulatory care utilization, a prospective, randomized, controlled trial was conducted with a Medicare population within a health maintenance organization. A statistically significant decrease of 15% in total medical visits was found in the experimental group as compared with a control. Although not evident in the control, a statistically significant decrease in the ratio of follow-up visits from pre-entry to postentry was realized in the experimental group. Medical-visit decreases resulted in a savings of $36.65 per household in the experimental group for a benefit-cost ratio of 2.19 saved for every dollar spent on intervention. These results demonstrate that a health education program can reduce utilization while having no known negative impact on the quality of health.

Mentorship and competencies for applied chronic disease epidemiology.
To understand the potential and establish a framework for mentoring as a method to develop professional competencies of state-level applied chronic disease epidemiologists, model mentorship programs were reviewed, specific competencies were identified, and competencies were then matched to essential public health services. Although few existing mentorship programs in public health were identified, common themes in other professional mentorship programs support the potential of mentoring as an effective means to develop capacity for applied chronic disease epidemiology. Proposed competencies for chronic disease epidemiologists in a mentorship program include planning, analysis, communication, basic public health, informatics and computer knowledge, and cultural diversity. Mentoring may constitute a viable strategy to build chronic disease epidemiology capacity, especially in public health agencies where resource and personnel system constraints limit opportunities to recruit and hire new staff.

Very young gay and bisexual men are at risk for HIV infection: the San Francisco Bay Area Young Men's Survey II.
OBJECTIVES: To compare HIV seroprevalence and sexual risk behavior among very young gay and bisexual men (aged 15-17 years) and their older counterparts (aged 18-22 years). To examine drug-use patterns and correlates of sexual risk behavior in both of these age groups. DESIGN AND METHODS: An interviewer-administered cross-sectional survey of 719 gay and bisexual males between 15 and 22 years old was conducted through a venue-based sampling design. Blood specimens were collected and tested for HIV antibodies, hepatitis B, and syphilis. Interviews assessed sexual and drug-use behavior as well as psychosocial variables believed to be related to sexual risk-taking, including self-acceptance of gay or bisexual identity, perceptions of peer norms concerning safer sex, and perceptions of the ability to practice safer sex (safer sex self-efficacy). RESULTS: Of the 719 participants, 100 (16.2%) were aged between 15 and 17 years. HIV seroprevalence was somewhat lower among those aged 15 to 17 years (2.0%) compared with those aged 18 to 22 years (6.8%). Overall, the prevalence of hepatitis-B core antibody was significantly lower in the younger age group (5.0%) than in the older group (14.1%). The men aged 15 to 17 years used alcohol, ecstasy, and heroin less frequently than those aged 18 to 22 years. The age groups did not differ in the proportion of men who reported any unprotected anal intercourse in the previous 6 months (31.2%). In both age groups, use of amphetamines, ecstasy, and amyl nitrate was associated with unprotected anal intercourse. Self-acceptance of gay or bisexual identity was related to less sexual risk for those aged 15 to 17 years. In both age groups, greater safer sex self-efficacy was linked to less HIV sexual risk-taking. In the younger group, perceptions of peer norms that support safer sex were related to less risk behavior. CONCLUSIONS: Very young gay and bisexual men engage in unprotected anal sex at rates comparable with those for their somewhat older counterparts, raising serious concern over their risk of acquiring HIV infection. To prevent seroconversions, interventions must target those <18 years of age, and prevention programs should address the use of certain drugs in relation to sex and sexual risk-taking. To be most effective, programs should develop innovative communication strategies to take into account lack of self-acceptance of gay or bisexual identity and low self-efficacy for practicing safer sex.

Positional accuracy of two methods of geocoding.
BACKGROUND: Geocoding is often used in epidemiologic studies to map residences with geographic information systems (GIS). The accuracy of the method is usually not determined. METHODS: We collected global positioning system (GPS) measurements at homes in a case-control study of non-Hodgkin lymphoma in Iowa. We geocoded the addresses by 2 methods: (1) in-house, using ArcView 3.2 software and the U.S. Census Bureau TIGER 2000 street database; and (2) automated geocoding by a commercial firm. We calculated the distance between the geocoded and GPS location (positional error) overall and separately for homes within towns and outside (rural). We evaluated the error in classifying homes with respect to their proximity to crop fields. RESULTS: Overall, the majority of homes were geocoded with positional errors of less than 100 m by both methods (ArcView/TIGER 2000, median = 62 m [interquartile range = 39-103]; commercial firm, median = 61 m [interquartile range = 35-137]). For town residences, the percent geocoded with errors of </=100 m was 81% for ArcView/TIGER 2000 and 84% for the commercial firm. For rural residences, a smaller percent of addresses were geocoded with this level of accuracy, especially by the commercial firm (ArcView/TIGER 2000, 56%; commercial firm, 28%). Geocoding errors affected our classification of homes according to their proximity to agricultural fields at 100 m, but not at greater distances (250-500 m). CONCLUSIONS: Our results indicate greater positional errors for rural addresses compared with town addresses. Using a commercial firm did not improve accuracy compared with our in-house method. The effect of geocoding errors on exposure classification will depend on the spatial variation of the exposure being studied.

Information object definition-based unified modeling language representation of DICOM structured reporting: a case study of transcoding DICOM to XML.
Supplement 23 to DICOM (Digital Imaging and Communications for Medicine), Structured Reporting, is a specification that supports a semantically rich representation of image and waveform content, enabling experts to share image and related patient information. DICOM SR supports the representation of textual and coded data linked to images and waveforms. Nevertheless, the medical information technology community needs models that work as bridges between the DICOM relational model and open object-oriented technologies. The authors assert that representations of the DICOM Structured Reporting standard, using object-oriented modeling languages such as the Unified Modeling Language, can provide a high-level reference view of the semantically rich framework of DICOM and its complex structures. They have produced an object-oriented model to represent the DICOM SR standard and have derived XML-exchangeable representations of this model using World Wide Web Consortium specifications. They expect the model to benefit developers and system architects who are interested in developing applications that are compliant with the DICOM SR specification.
