- ItemCompetence on demand in DNA image cytometry.(2000-08-25) Haroske, G; Meyer, W; Oberholzer, M; Böcking, A; Kunze, K DQuantitation methods in clinical pathology have to be normalized and standardized both from the instrumental and the methodological point of view to guarantee a defined level of precision and accuracy independent of the site where they are applied The comparability of results obtained in different laboratories is the basis for the application of standardized diagnostic classification systems and therapeutic schemes Remote quantitation based on standardized evaluation tools could be a way to reach the goals mentioned above Diagnostic DNA image cytometry increasingly used as a routine method in clinical pathology will serve as an example for demonstrating the feasibility and usefulness of a concept of remote quantitation We report a system for a remote DNA ploidy analysis based on client server technology and accessible via Internet or ISDN connections Quantitation Server EUROQUANT This system i allows the cytometric measurement of the DNA content of cells for diagnostic purposes ii provides the user with comprehensive quality control of such measurements iii helps in trouble shooting and iv gives assistance in diagnostic interpretation The system uses the principles of telepathology and Internet technology To date more than 40 laboratories from Europe USA and Asia have successfully performed analyses on about 3 000 ploidy data sets
- Item[The future of telepathology. An Internet "distributed system" with "open standards"].(2002-07-01) Brauchli, K; Helfrich, M; Christen, H; Jundt, G; Haroske, G; Mihatsch, M; Oberli, H; Oberholzer, MWith the availability of Internet the interest in the possibilities of telepathology has increased considerably In the foreground is thereby the need of the non expert to bring in the opinions of experts on morphological findings by means of a fast and simple procedure The new telepathology system iPath is in compliance with these needs The system is based on small but when possible independently working modules This concept allows a simple adaptation of the system to the individual environment of the user e g for different cameras frame grabbers microscope steering tables etc and for individual needs iPath has been in use for 6 months with various working groups In telepathology a distinction is made between passive and active consultations but for both forms a non expert brings in the opinion of an expert In an active consultation both are in direct connection with each other orally or via a chat function this is however not the case with a passive consultation An active consultation can include the interactive discussion of the expert with the non expert on images in an image database or the direct interpretation of images from a microscope by the expert Four software modules are available for a free and as fast as possible application 1 the module Microscope control 2 the module Connector insertion of images directly from the microscope without a motorized microscope 3 the module Client application via the web browser and 4 the module Server with a database The server is placed in the internet and not behind a firewall The server permanently receives information from the periphery and returns the information to the periphery on request The only thing which the expert the non expert and the microscope have to know is how contact can made with the server
- ItemiPath - a Telemedicine Platform to Support Health Providers in Low Resource Settings.(2005-05-30) Brauchli, K; O'mahony, D; Banach, L; Oberholzer, MIn many developing countries there is an acute shortage of medical specialists The specialists and services that are available are usually concentrated in cities and health workers in rural health care who serve most of the population are isolated from specialist support 1 Besides the few remaining specialist are often isolated from colleagues With the recent development in information and communication technologies new option for telemedicine and generally for sharing knowledge at a distance are becoming increasingly accessible to health workers also in developing countries Since 2001 the Department of Pathology in Basel Switzerland is operating an Internet based telemedicine platform to assist health workers in developing countries Over 1800 consultation have been performed since This paper will give an introduction to iPath the telemedicine platform developed for this project and analyse two case studies a teledermatology project from South Africa and a telepathology project from Solomon Islands
- ItemPacific Telepathlogy Service at Fiji School of Medicine.(2008-01-09) Shashidhar, V M; Brauchli, K; Oberholzer, M; Pryor, J; Kishore, K; Krishna, RoyPacific Telepathology service has been established at Fiji school of Medicine FSM with technical support from University of Basel The service is designed for remote consultation continuing medical education CME health care research HCR To develop Telepathology services for participation with international Telepathology community for improving quality of health care in the Pacific Telepathology server for Pacific Pathology Group has been set up at http telepath patho unibas ch which is dedicated for Telepathology consultations bring together health care professionals in the Pacific to overcome limitations of distance lack of resources and to improve quality of healthcare services Accessed by a computer possessing Internet and email connection members send cases and questions review and comment on other cases and receive consultation via web or email Benefits are tremendous in terms of remote consultation CME HCR and improving quality of modern health care even at remote islands devoid of health care resources Internet speed or reliability is not a limiting factor Virtual institute of pathology has been established in Switzerland with over 400 Pathologists and is providing consultations to many countries including Solomon Islands where there is no pathologist The institute is functioning efficiently with average reporting turnaround time of 48 hours Efficiency is the result of organization and communication Presently this Service has been established at the FSM in Fiji Islands primarily for education And remote consultation with plans to expand to other island countries
- Item[Telemedicine: perspectives and multidisciplinary approach].(2000-05-03) Demartines, N; Battegay, E; Liebermann, J; Oberholzer, M; Rufli, T; Harder, FTelemedicine is use of the new computer based communication technologies for medical purposes It augments the exchange of scientific information while its applications in the fields of patient care and medical education cover remote diagnosis and therapy as well as remote education and training
- ItemTelemicroscopy by the Internet revisited.(2002-01-16) Brauchli, K; Christen, H; Haroske, G; Meyer, W; Kunze, K D; Oberholzer, MThis paper reports a fundamentally new concept for internet based telemicroscopy By separating a telemicroscopy application into three tasks microscope control program external server and client application it is possible to establish a telemicroscopy session between two arbitrary end points on the Internet even if both of the end points are secured by firewall microscope and client application The advantages of such a distributed system compared with the classical point to point systems are discussed The telemicroscopy system is combined with a telepathology database which is capable of automatically recording telemicroscopy sessions allowing a convenient combination of interactive remote microscopy and store and forward telepathology In addition to remote primary diagnosis it is easily possible to discuss difficult cases within dedicated user groups no matter whether images originate from a telemicroscopy session or are manually entered into the database
- ItemTelepathology on the Solomon Islands--two years' experience with a hybrid Web- and email-based telepathology system.(2004-12-17) Brauchli, K; Jagilly, R; Oberli, H; Kunze, K D; Phillips, G; Hurwitz, N; Oberholzer, MThe National Referral Hospital in Honiara Solomon Islands has used an Internet based system in Switzerland for telepathology consultations since September 2001 Due to the limited bandwidth of Internet connections on the Solomon Islands an email interface was developed that allows users in Honiara to submit cases and receive reports by email At the other end consultants can use a more sophisticated Web based interface that allows discussion of cases among an expert panel The result is a hybrid email and Web based telepathology system Over two years 333 consultations were performed in which 94 of cases could be diagnosed by a remote pathologist A computer assisted virtual institute of pathologists was established This form of organization helped to reduce the median time from submission of the request to a report from 28 h to 8 5 h for a preliminary diagnosis and 13 h for a final report A final report was possible in 77 of all submitted cases
- ItemTelepathology: design of a modular system.(2001-05-07) Brauchli, K; Christen, H; Meyer, P; Haroske, G; Meyer, W; Kunze, K D; Otto, R; Oberholzer, MAlthough telepathology systems have been developed for more than a decade they are still not a widespread tool for routine diagnostic applications Lacking interoperability software that is not satisfying user needs as well as high costs have been identified as reasons In this paper we would like to demonstrate that with a clear separation of the tasks required for a telepathology application telepathology systems can be built in a modular way where many modules can be implemented using standard software components With such a modular design systems can be easily adapted to changing user needs and new technological developments and it is easier to integrate modular systems into existing environments
