[Participation of anesthesiologists in the Internet].

The author classified the e-mail addresses of the mailing list "Masui Discussion List" users. The result indicates that the types of the participation of those users in the Internet are classified into the following three: (1) Use of the network of employment places such as universities and hospitals or their facilities, (2) Via the BBS (Bulletin Board System) host, and (3) Contract with a network service provider. The author estimates the following: Type (1) occupies about half of the whole types. Types (2) and (3) occupy about a quarter of the whole types, respectively. If the network of the employment place cannot be used to access the Internet, dial-up IP connection can be made by contracting with a network service provider. To make such a connection, a multimedia personal computer, dial-up IP connection software, a high-speed modem or a terminal adapter, and variety of Internet application software such as World Wide Web browser are required in addition to the telephone line (analog or ISDN).

Limits to trophic levels and omnivory in complex food webs: theory and data.

While trophic levels have found broad application throughout ecology, they are also in much contention on analytical and empirical grounds. Here, we use a new generation of data and theory to examine long-standing questions about trophic-level limits and degrees of omnivory. The data include food webs of the Chesapeake Bay, U.S.A., the island of Saint Martin, a U.K. grassland, and a Florida seagrass community, which appear to be the most trophically complete food webs available in the primary literature due to their inclusion of autotrophs and empirically derived estimates of the relative energetic contributions of each trophic link. We show that most (54%) of the 212 species in the four food webs can be unambiguously assigned to a discrete trophic level. Omnivory among the remaining species appears to be quite limited, as judged by the standard deviation of omnivores' energy-weighted food-chain lengths. This allows simple algorithms based on binary food webs without energetic details to yield surprisingly accurate estimates of species' trophic and omnivory levels. While maximum trophic levels may plausibly exceed historically asserted limits, our analyses contradict both recent empirical claims that these limits are exceeded and recent theoretical claims that rampant omnivory eliminates the scientific utility of the trophic-level concept.

Model-driven user interfaces for bioinformatics data resources: regenerating the wheel as an alternative to reinventing it.

BACKGROUND: The proliferation of data repositories in bioinformatics has resulted in the development of numerous interfaces that allow scientists to browse, search and analyse the data that they contain. Interfaces typically support repository access by means of web pages, but other means are also used, such as desktop applications and command line tools. Interfaces often duplicate functionality amongst each other, and this implies that associated development activities are repeated in different laboratories. Interfaces developed by public laboratories are often created with limited developer resources. In such environments, reducing the time spent on creating user interfaces allows for a better deployment of resources for specialised tasks, such as data integration or analysis. Laboratories maintaining data resources are challenged to reconcile requirements for software that is reliable, functional and flexible with limitations on software development resources. RESULTS: This paper proposes a model-driven approach for the partial generation of user interfaces for searching and browsing bioinformatics data repositories. Inspired by the Model Driven Architecture (MDA) of the Object Management Group (OMG), we have developed a system that generates interfaces designed for use with bioinformatics resources. This approach helps laboratory domain experts decrease the amount of time they have to spend dealing with the repetitive aspects of user interface development. As a result, the amount of time they can spend on gathering requirements and helping develop specialised features increases. The resulting system is known as Pierre, and has been validated through its application to use cases in the life sciences, including the PEDRoDB proteomics database and the e-Fungi data warehouse. CONCLUSION: MDAs focus on generating software from models that describe aspects of service capabilities, and can be applied to support rapid development of repository interfaces in bioinformatics. The Pierre MDA is capable of supporting common database access requirements with a variety of auto-generated interfaces and across a variety of repositories. With Pierre, four kinds of interfaces are generated: web, stand-alone application, text-menu, and command line. The kinds of repositories with which Pierre interfaces have been used are relational, XML and object databases.

Cost-effective gel documentation using a web-cam.

In search for a cost effective gel documentation system applicable for different fields of molecular biology, we analyzed the capabilities of a cheap CCD-camera originally designed to capture images for transmission through the internet (web-cam) with regard to gel documentation. The camera was connected to a personal computer by universal serial bus (USB) and used for the documentation of DNA separated on agarose gels and stained by ethidium-bromide using the software provided with the camera. The web-cam provided digital images of sufficient quality for routine documentation and combined the low set-up costs of a Polaroid system with the low running costs of video capture systems, hence is ideal as a start-up system and as augmentation to existing equipment.

Teaching teachers about childhood cancer: the effects of a web-based training program.

The purpose of this study was to examine the utility and acceptability of a modular computer-based training program on childhood cancer (eg, acute and late effects of treatment, intervention strategies) for teachers. A within-subjects design was implemented with 41 teachers and teachers in training. Participants completed tests of childhood cancer knowledge and application skills both before and after completing the web-based training. An acceptability questionnaire was completed after the training. Results indicated significant gains in knowledge and in case application, as well as high levels of acceptability of the training. It seems that a web-based training program can be accessed by teachers and in 2 to 4 hours can significantly increase cancer knowledge in an acceptable manner.

Secondary coverage of the hand using a dorsalis pedis plus first web space free flap.

Traditionally, severe degloving injuries of the hand have been treated with random abdominal or pedicled groin flaps, which offer good cutaneous coverage but do not provide sensibility. The authors present the results of the application of an extended dorsalis pedis plus first web space of the foot flap to resurface the hands of five male patients who had been treated originally with random abdominal or pedicled groin flaps. The reported flap has the advantage of providing the patient with up to three different nerve territories, aiding in a better functional use of the hand.

The medical school Web site: medical education's newest tool.

There are few technological advancements that have had as much impact on the dissemination of information as the Internet, and especially the worldwide web. It is not surprising then that this tool is also changing the way medicine is studied, taught and practiced today. This impressive infrastructure enables us to teach and study medicine in an entirely different way. The web provides medical students and physicians with access to continuing medical education, patient education services, telemedicine, and unparalleled communication between colleagues via email. The medical school web site may be used as a dynamic newspaper or bulletin board to disseminate information internally among the faculty as well as to the outside world. It can also be the vehicle for virtual learning modules that enhance the medical school core curriculum by including lectures, exercises, tests, etc. In addition, the web allows the student access to medical literature, medical software applications and medical resource depots. To date no work has been published on the medical school web site, its construction process, and its advantages, drawbacks and future. The purpose of this article is to examine the evolution of the web as a tool for medical schools, medical students and associated physicians. We discuss the building of a web site for a medical faculty, and look to the future.

Singapore National Medical Image Resource Centre (SN.MIRC): a world wide web resource for radiology education.

Radiology education is heavily dependent on visual images, and case-based teaching files comprising medical images can be an important tool for teaching diagnostic radiology. Currently, hardcopy film is being rapidly replaced by digital radiological images in teaching hospitals, and an electronic teaching file (ETF) library would be desirable. Furthermore, a repository of ETFs deployed on the World Wide Web has the potential for e-learning applications to benefit a larger community of learners. In this paper, we describe a Singapore National Medical Image Resource Centre (SN.MIRC) that can serve as a World Wide Web resource for teaching diagnostic radiology. On SN.MIRC, ETFs can be created using a variety of mechanisms including file upload and online form-filling, and users can search for cases using the Medical Image Resource Center (MIRC) query schema developed by the Radiological Society of North America (RSNA). The system can be improved with future enhancements, including multimedia interactive teaching files and distance learning for continuing professional development. However, significant challenges exist when exploring the potential of using the World Wide Web for radiology education.

MedWeaver: integrating decision support, literature searching, and Web exploration using the UMLS Metathesaurus.

Integrating functions from disparate and widely-distributed information systems has been an interest of the medical informatics community for some time. Barriers to progress have included the lack of network-accessible information sources, inadequate methods for inter-system messaging, and lack of vocabulary translation services. With the advent of the World Wide Web (WWW) and the evolution of the National Library of Medicine's Unified Medical Language System (UMLS), it is now possible to develop applications that integrate functions from diverse, distributed systems. In this paper we describe one such system, MedWeaver, a WWW application that integrates functions from a decision support application (DXplain), a literature searching system (WebMedline), and a clinical Web searching system (CliniWeb) using the UMLS Metathesaurus for vocabulary translation. This system demonstrates how application developers can design systems around anticipated clinical information needs and then draw together the needed content and functionality from diverse sources.

Web multimedia information retrieval using improved Bayesian algorithm.

The main thrust of this paper is application of a novel data mining approach on the log of user's feedback to improve web multimedia information retrieval performance. A user space model was constructed based on data mining, and then integrated into the original information space model to improve the accuracy of the new information space model. It can remove clutter and irrelevant text information and help to eliminate mismatch between the page author's expression and the user's understanding and expectation. User space model was also utilized to discover the relationship between high-level and low-level features for assigning weight. The authors proposed improved Bayesian algorithm for data mining. Experiment proved that the authors' proposed algorithm was efficient.

Evolution of a legacy system to a Web patient record server: leveraging investment while opening the system.

A layered system is under development to enhance our legacy system as a backend in a WEB-enabled system. Each layer of the system has defined functionality, leverages the investment in the layer below, and follows the strategy of reducing support requirements for workstations. The mainframe system provides administrative integration of sub-systems, security, and the central data repository for most information. The second layer is a graphical user interface (GUI) to the system for Windows platforms. Support needs are limited by relying chiefly on X-terminals and application servers. The "Intranet" layer is a WEB Server building upon the second layer gateways to provide platform-independent access to selected information and images. The fourth layer, under evaluation, will extend access to the central data repository for Internet users of web browsers that support private-key/public-key encryption.

Twelve weeks of nightly stretch does not reduce thumb web-space contractures in people with a neurological condition: a randomised controlled trial.

QUESTION: What is the effectiveness of 12 weeks of nightly stretch in reducing thumb web-space contracture in people with neurological conditions? DESIGN: Assessor-blinded, randomised controlled trial. PARTICIPANTS: Forty-four (one dropout)community-dwelling patients with a neurological condition (14 stroke, 7 traumatic brain injury, 23 spinal cord injury) who had uni or bilateral thumb web-space contractures (60 thumbs). INTERVENTION: The experimental thumbs were splinted into a stretched,abducted position each night for 12 weeks. The control thumbs were not splinted. OUTCOME MEASURES: Thumb web-space was measured as the carpometacarpal angle during the application of a 0.9 Nm abduction torque before and after intervention. RESULTS: The mean increase in thumb web-space after 12 weeks was 1 deg (95% CI, -1 to 2). CONCLUSION: Intensive stretch administered regularly over three months does not reduce thumb web-space contractures in neurological conditions.

[Value of a new first web space reconstruction in congenital hand deformities. A study of 54 patients].

INTRODUCTION: Only a few studies are available in the literature on the specific problem of the congenital contracture or absence of the first web in hand deformities, and first web reconstruction. MATERIAL AND METHODS: Sixty-seven first web plasties in 54 patients were retrospectively analyzed: they included 44 cases of classical plasties, i.e., Z-plasty (21 cases); dorsal flap plasty of the index (19 cases), thumb (1 case), or the hand (10 cases), and 16 cases of' pseudo-kite flap. RESULTS: The results were difficult to assess, as the syndromes were dissimilar and the deformities were not comparable (e.g., Apert syndrome versus Poland syndrome). However, it was found that the 'pseudo-kite' technique which was applicable to certain cases resulted in a web extension of 3.2 cm without any deepening. DISCUSSION: No method of classical assessment can be used to comprehensively evaluate the results of first web reconstruction due to the wide variability in clinical characteristics, the lack of patient cooperation in this young age group, the possible MPJ articular thumb instability, and growth factors. Although 4-flap Z-plasty is an adequate technique for non-severe first web deformities, the 'pseudo-kite' flap approach is useful in more severe cases. In 13 cases, a peroperative measurement before and following plasty was made, and a significant increase (205%) in planimetric and stereotactic gain compared to pre-plasty findings was noted. CONCLUSION: It does not seem logical to have a particular preference for a certain approach when considering first web reconstruction in congenital malformations. Each technique has its advantages and disadvantages, depending on patient age, the type of malformation, the state of the thumb, the extent of the first web deformity and the possible presence of scar tissue.

Use of the World Wide Web for multisite data collection.

As access to the Internet becomes increasingly available, research applications in medicine will increase. This paper describes the use of the Internet, and, more specifically, the World Wide Web (WWW), as a channel of communication between EDs throughout the world and investigators who are interested in facilitating the collection of data from multiple sites. Data entered into user-friendly electronic surveys can be transmitted over the Internet to a database located at the site of the study, rendering geographic separation less of a barrier to the conduction of multisite studies. The electronic format of the data can enable real-time statistical processing while data are stored using existing database technologies. In theory, automated processing of variables within such a database enables early identification of data trends. Methods of ensuring validity, security, and compliance are discussed.
