Trauma and disaster as life disrupters: A model of computer-assisted psychotherapy applied to adolescent victims of the Chernobyl disaster.

This article reports on a computer-based, psychologist-assisted technology for addressing posttraumatic responses in Chernobyl-disaster-affected children. Mental health professionals who worked with this population reveal substantially distorted thoughts and feelings about the children's past, present, and future more than others of their age. Chernobyl-affected and evacuated children are aware that they can never return to their homes, illnesses may befall them in childhood, their parents may die sooner than normal, and that their environment is poisoned. The LifeLine psychotherapeutic software program (available from A. Kronik), which is based on the goal-and-causal theory of psychological time is described and suggestions are given for further school-based intervention and prevention services.

Participatory action research as a strategy for empowering aboriginal health workers

A participatory action research project was undertaken with Aboriginal health workers on the Anangu Pitjantjatjara Lands in South Australia. The study examined the factors that affect the empowerment of Aboriginal health workers within the context of an Aboriginal-controlled primary health care service. This project was different from previous research conducted with Aboriginal health workers in remote areas for two reasons. First, it enabled them to participate actively as co-researchers in the study, and second, it brought about action and change during the research process. The three main factors preventing Aboriginal health workers from attaining a key role within the health service are the standard of training they receive, their low literacy and numeracy levels, and their lack of participation in decision making within the health service. Each of these factors is interrelated and all affect the Aboriginal health workers' ability to have more control and responsibility within the health service.     

Attitude of French general practitioners to the public health surveillance of communicable diseases

BACKGROUND: The attitude of general practitioners (GPs) to public health surveillance is not well documented, even though they furnish essential information, in particular for sentinel surveillance among the general population. METHODS: The attitude of 560 French GPs to the surveillance of 17 communicable diseases was researched. Half the GPs had previous experience in public health surveillance and the other half did not. Their motivation for belonging to a public health surveillance network and some of their demographic characteristics were also investigated. Their attitude was compared with an objective evaluation of public health surveillance priorities, based on 10 criteria. RESULTS: Primarily, GPs are interested in the surveillance of uncommon and serious diseases (HIV infection, tuberculosis, meningitis), and/or preventable ones (viral hepatitis, flu' syndrome, measles, sexually transmitted diseases), which coincides with the choices made by public health decision makers. The age of the GPs, their type of practice (urban/rural), and their participation (or not) in a surveillance network modify their priorities: in general the GPs' perception of the risks to which their patients may be exposed influences their choice of which diseases should be subject to surveillance in general medicine.     

Prevention of nosocomial transmission of Mycobacterium tuberculosis

The recent resurgence of TB together with the ongoing HIV epidemic has resulted in a larger number of infectious TB patients being admitted to US health care facilities. These patients have become a source for both nosocomial (patient-to-patient) and occupational (patient-to-health care worker) M. tuberculosis transmission. Infectious MDR-TB patients serve as even greater potential infectious sources because they often remain AFB smear and culture positive for months to years. The keys to the prevention of nosocomial and occupational transmission of M. tuberculosis is conducting a risk assessment for each area of the facility and instituting appropriate control measures, having a high index of suspicion by clinicians for infectious TB in those who present with consistent signs and symptoms, rapid triage of such patients to isolation areas and their appropriate clinical work-up, and the institution of effective antituberculous therapy. Infection control personnel should ensure that infectious TB patients are isolated in appropriate isolation rooms (i.e., negative pressure, greater than or equal to 6 ACH, and direct external exhaust of the room air). Health care workers with infectious TB patient contact should be instructed in the epidemiology of M. tuberculosis transmission, the role of respirators in protecting the health care worker from airborne inoculation, and the importance of periodic health care worker TST. The nosocomial TB outbreaks in the 1980s and 1990s document that M. tuberculosis can be transmitted to both patients and health care workers in US health care facilities when appropriate infection control measures are not fully implemented. Follow-up studies at some of these institutions, however, document that when infection control measures similar to the 1990 or 1994 CDC TB Guidelines are fully implemented, M. tuberculosis transmission to both patients and health care workers can be reduced or eliminated. Protection of both patients and health care workers from M. tuberculosis infection is dependent on an understanding and full implementation of the 1994 CDC TB Guidelines.     

The GI Project: a prototype electronic textbook for high school biology

A prototype electronic science textbook for secondary education was developed to help bridge the gap between state-of-the-art medical technology and the basic science classroom. The prototype combines the latest in radiologic imaging techniques with a user-friendly multimedia computer program to teach the anatomy, physiology, and diseases of the gastrointestinal (GI) tract. The program includes original text, illustrations, photographs, animations, images from upper GI studies, plain radiographs, computed tomographic images, and three-dimensional reconstructions. These features are intended to create a stimulus-rich environment in which the high school science student can enjoy a variety of interactive experiences that will facilitate the learning process. The computer-based book is a new educational tool that promises to play a prominent role in the coming years. Current research suggests that computer-based books are valuable as an alternative educational medium. Although it is not yet clear what form textbooks will take in the future, computer-based books are already proving valuable as an alternative educational medium. For beginning students, they reinforce the material found in traditional textbooks and class presentations; for advanced students, they provide motivation to learn outside the traditional classroom.     

Caries preventive services for children and adolescents in Denmark, Iceland, Norway and Sweden: strategies and resource allocation

Construction workers are exposed to considerable hazards carrying a health risk, e.g., dusts, fumes, noise and manual handling, yet there is often poor occupational health service provision particularly for subcontracted labourers. This paper presents seven case studies from large, engineering construction organizations, concerning current practice in occupational health management. The results supported the fact that data and records regarding health-related absence were limited and inconsistent, and that little existed in terms of medicals and health surveillance, particularly in the case of subcontracted workers. The main difficulties envisaged were reported to be the sizeable costs involved; the temporary and mobile work force; demonstrating cost-benefits to top management and a lack of interest amongst workers, perhaps exacerbated by the threat of lost livelihood. Managers also admitted limited health expertise and knowledge of the wider role health professionals could play in health management. Training and further research in this area are indicated.     

Basics of surveillance--an overview

Surveillance of nosocomial infections is the foundation of an infection control program. This article describes components of a surveillance system, methods for surveillance, methods for case-finding, and data sources. We encourage the epidemiology team to use this background information as they design surveillance systems that meet the goals of their individual institution's infection control program.

To use or not to use: Clinicians' perceptions of telemental health.

Equal access to mental health services is necessary for healthy individuals and communities. However, due to geographical distances and other barriers, some clients cannot easily access mental health professionals. Technologies such as videoconferencing for clinical purposes (i.e., telemental health) may help to bridge these gaps to connect clients and clinicians at geographically diverse locations. However, despite its potential utility, telemental health has not been widely adopted in Canada. This study is an exploratory investigation into mental health professionals' attitudes toward telemental health, factors that affect the frequency with which they use this technology, and their perceptions of individual characteristics that make clients more or less suitable candidates for telemental health. This study has a particular focus on remote and rural and Operational Stress Injury (OSI) contexts. One hundred sixty mental health workers across Canada participated in an online survey, and 25 mental health workers from Operational Stress Injury clinics across Canada participated in in-person interviews. The data were examined using qualitative and quantitative analysis methods. Findings suggest that mental health workers have overall positive attitudes toward the use of telemental health—particularly for clients in remote and rural locations. Additionally, receiving training in telemental health, being in the mental health field for longer, and perceiving the technology as easy to use are associated with more frequent use of telemental health. Finally, clinicians reported specific client characteristics that they perceive to make some clients unsuitable candidates for telemental health. Implications of these findings and directions for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Neurobehavioral tests as a medical surveillance procedure: applying evaluative criteria

Neurobehavioral impairment is among the earliest indicators of a toxic insult on the nervous system. Neurobehavioral tests measure behavior impairment by noninvasive procedures that assess various performance and personality changes. Neurobehavioral tests have been used on groups of workers included in epidemiologic research studies; however, their suitability for an ongoing medical surveillance program for workers exposed to neurotoxic agents has not been evaluated. In Ontario, Canada, a set of validity criteria must be met to determine whether a medical procedure may be prescribed for a specific medical surveillance program. The evaluative criteria are standards for judging the desirability of a procedure based on social values and scientific considerations. In this paper, various studies using neurobehavioral tests are reviewed, and the validity of using these procedures for medical surveillance is evaluated by applying the Ontario evaluation criteria. The conclusion is that neurobehavioral tests are useful for well-controlled, cross-sectional studies, but they do not yet meet the validity criteria for procedures prescribed in an ongoing medical surveillance program for workers exposed to neurotoxic agents.     

Training drug abuse treatment personnel in therapeutic community methodologies.

Describes the therapeutic community (TC) philosophy, which is based on the social learning model, and examines the various types of training that the TC personnel bring to the community. Clients in TCs have tasks assigned to them, and they attain status by earning the respect of fellow clients and by working through 4 levels of competence. The rapid growth of TCs in the last 20 yrs has led to an increase in the number of professional mental health workers in this field. Thus, most TCs now have both TC-recovered personnel and mental health personnel on their staff, and these 2 groups must learn from each other, despite any resistance they might feel. A basic training format and curriculum guide are presented for training TC personnel. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Localizing and Designing Computer-Based Safety Training Solutions for Hispanic Construction Workers

Despite the construction industry’s generally positive reaction to the use of information and communication technologies (ICTs) in many of its functions, some of the profession’s key players reside in a digital divide and do not benefit from advances in technology. Hispanic construction workers, an at-risk population with high rates of workplace accidents, are affected by that divide because they rarely take advantage of available ICTs at work. One application of ICTs that can help Hispanic/Latino workers is computer-based training (CBT) for occupational safety. However, the design of CBT materials for Spanish-speaking workers needs to go beyond basic localization of existing products in English. A radical localization approach that uses participatory design sessions with construction workers and their supervisors is proposed in this paper. This case study reports that Latino workers reacted positively and retained knowledge from CBT materials, including videos with elements of humor and without graphic representations of accidents, modeled after the genre of a television situation comedy.     

Surgical treatment of difficult patent ductus arteriosus and related operative complications]

Data of health surveillance from 1970 to 1989 for the workers employed in dipterex packaging were collected and statistically analyzed with a microcomputer by scoring their whole blood choline esterase activities and symptoms and signs. Results showed working environment improved and air pollution and absorption of pollutants via skin decreased with technology innovation and longterm hygienic supervision, monitoring and health surveillance in the factory. Incidence of dipterex poisoning in workers employed in the department of pesticide packaging lowered significantly, from 25.26% in the early 1970's to 5.17% in late 1970's and to 1.85% during 1980's, with periodical physical examinations for them, and timely management of the patients with poisoning and the cases at high risk.     

Epiduroscopy with access via the sacral canal. Some constructional equipment requirements from the anatomic and biomechanical viewpoint

Food safety is a complex matter that depends on a number of interrelated environmental, cultural, and socioeconomic factors. The purpose of epidemiology and surveillance is to define these factors, how they interact, and their relative importance in foodborne infections. The tools epidemiologists use to study foodborne disease include surveillance of specific infections in humans, monitoring of contamination with specific pathogens in foods and animals, intensive outbreak investigations, collecting reports of outbreaks at the regional or national level, and studies of sporadic infections. With sufficiently elaborate systems of surveillance and investigation, it is possible to provide quantitative risk data for foodborne diseases that will permit the wisest allocation of food safety resources.     

Client-centred approach to student nurse education in mental health practicum: an inquiry

This project utilized constructive feedback from clients of mental health facilities as a means of facilitating student nurse learning in three clinical environments. Three questionnaires were utilized to elicit and evaluate the impact of this feedback with a sample of 43 students and 74 client participants. The inquiry demonstrated that clients are willing to participate in students learning and believe that they can contribute towards it. Students also believed that clients have a valuable role to play in their learning, although they note caution in regards to client selection.     

Surveillance of foodborne diseases: what are the options?

Epidemiological data are needed for a variety of reasons, namely, informing public health authorities about the nature and magnitude of foodborne illnesses and their epidemiology, for the early detection of foodborne disease outbreaks, and for the planning, implementation and evaluation of food safety programmes. Thus, epidemiological surveillance of foodborne diseases is fundamental to any food safety programme. Various methods of foodborne surveillance may be utilized: (i) records for registration of deaths and hospital discharges; (ii) disease notification, (iii) sentinel surveillance, (iv) laboratory surveillance, (v) outbreak investigation and (vi) epidemiological research. This article reviews each method, its advantages and disadvantages, and its relevance for meeting the various objectives and needs.     

A critique of multiculturalism in heath care: the challenge for nurse education

This paper is concerned with the way in which discussions of the health status of people from minority ethnic groups and the delivery of health care to such groups has been constructed, in the nursing literature in particular, within a culturalist framework which has many serious drawbacks. The paper reviews the argument for a 'multicultural' approach to health care and also discusses some of the main implications of this analysis for the education of health professionals. It suggests that health workers and those responsible for the education of such workers, need to reassess learning needs in the light of a critique of the effects of an analysis based on 'cultural pluralism' and 'ethnic sensitivity'. The paper suggests ways in which the nursing curriculum must be broadened to take into account the limitations of a culturalist approach and to debate the interplay of racism and other structures of inequality and their influence on health and on a service delivery.     

Computer-aided veterinary learning at the University of Cambridge

An approach of computer-assisted learning in veterinary education at the University of Cambridge, involving the development of four types of learning module, is outlined. A tutorial on regional perineural anaesthesia in the horse, based on the familiar tape-slide format but with significant improvements, is described. A question and answer self-assessment package and a computer-based 'digital lecture' are also discussed, together with a case simulation involving the investigation of a polydipsic dog. All the tutorials were developed using standard software packages and image digitising processes. The philosophy behind the development of these computer-assisted learning packages is discussed.     

Rare disease surveillance

Rare diseases in children account for disproportionate morbidity and mortality and are particularly demanding of both families and health resources. Surveillance may provide data on their epidemiology, aetiology, management and outcome and on the support requirements of affected children. Existing methods for rare disease surveillance include mandatory and voluntary notification schemes, which may be active or passive, hospital discharge databases and death certification data. The recent establishment of the Australian Paediatric Surveillance Unit has facilitated active, prospective, national case ascertainment by voluntary notification of selected rare conditions. Information obtained should enable estimation of incidence rates, evaluation of prevention and management strategies, extend data collected by existing methods and help estimate future health needs.
