Evaluation of medical decision support systems (DDX generators) using real medical cases of varying complexity and origin. BMC Med Inform Decis Mak 2022; 22:254. [PMID: 36153527 PMCID: PMC9509605 DOI: 10.1186/s12911-022-01988-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 08/29/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Medical decision support systems (CDSSs) are increasingly used in medicine, but their utility in daily medical practice is difficult to evaluate. One variant of CDSS is a generator of differential diagnoses (DDx generator). We performed a feasibility study on three different, publicly available data sets of medical cases in order to identify the frequency in which two different DDx generators provide helpful information (either by providing a list of differential diagnosis or recognizing the expert diagnosis if available) for a given case report.
Methods
Used data sets were n = 105 cases from a web-based forum of telemedicine with real life cases from Afghanistan (Afghan data set; AD), n = 124 cases discussed in a web-based medical forum (Coliquio data set; CD). Both websites are restricted for medical professionals only. The third data set consisted 50 special case reports published in the New England Journal of Medicine (NEJM). After keyword extraction, data were entered into two different DDx generators (IsabelHealth (IH), Memem7 (M7)) to examine differences in target diagnosis recognition and physician-rated usefulness between DDx generators.
Results
Both DDx generators detected the target diagnosis equally successfully (all cases: M7, 83/170 (49%); IH 90/170 (53%), NEJM: M7, 28/50 (56%); IH, 34/50 (68%); differences n.s.). Differences occurred in AD, where detection of an expert diagnosis was less successful with IH than with M7 (29.7% vs. 54.1%, p = 0.003). In contrast, in CD IH performed significantly better than M7 (73.9% vs. 32.6%, p = 0.021). Congruent identification of target diagnosis occurred in only 46/170 (27.1%) of cases. However, a qualitative analysis of the DDx results revealed useful complements from using the two systems in parallel.
Conclusion
Both DDx systems IsabelHealth and Memem7 provided substantial help in finding a helpful list of differential diagnoses or identifying the target diagnosis either in standard cases or complicated and rare cases. Our pilot study highlights the need for different levels of complexity and types of real-world medical test cases, as there are significant differences between DDx generators away from traditional case reports. Combining different results from DDx generators seems to be a possible approach for future review and use of the systems.

Abstract
Afghanistan is in a military conflict lasting more than 20 years and according to recent political development, in a downhill spiral towards a failed society. This scenario faces the question of the usefulness of international medical aid, especially morphological diagnostics in crisis situations. On the basis of ten years of experience from a telemedicine project, need, feasibility and results in Afghanistan will be discussed. General and country-specific problems and the sustainability of an international partnership are discussed. In summary our experience is: (1) Telemedicine is possible and necessary even in countries with high conflict potential. It is integrated into routine care by local medical care taker, (2) Accompanying video conferences are a significant improvement in telemedical diagnostics, (3) "High level" consultations can bridge the gap between sophisticated western diagnostics and medicine in the partner country in selected cases and (4) Scientific work is possible on the basis of the medical data collected on site and the image material generated.

The Importance of Clinical Data for the Diagnosis of Breast Tumours in North Afghanistan. Int J Breast Cancer 2021; 2021:6625239. [PMID: 34373791 PMCID: PMC8349267 DOI: 10.1155/2021/6625239] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 06/24/2021] [Accepted: 07/14/2021] [Indexed: 12/03/2022] Open
Abstract
Background This study was performed in knowledge of the increasing gap between breast disease treatment in countries with restricted resources and developed countries with increasingly sophisticated examination methods. Methods The authors present the analysis of a breast disease register consisting of diagnostic cases from Mazar e Sharif and Herat in 2018 and 2019. The study comprises a total of 567 cases, which were presented to experts via telemedicine for final diagnosis. 62 cases (10.9%) were excluded due to inacceptable data or insufficient image quality. These data provided by daily diagnostic classification were used for the built-up of a profile for each frequent breast disease and a breast cancer register. All images and cases were seen by at least 3 independent experts. The diagnoses were made in 60% of cases by cytology of fine needle aspiration and in 40% by histological images. Results For each entity of breast diseases (e.g., fibroadenoma), a profile of context variables was constructed allowing to assist medical decisions, as “wait and see,” elective surgery or immediate surgical intervention with R0 (complete) resection. These “profiles” could be described for fibroadenoma, mastitis, galactocele, fibrous-cystic disease, and invasive breast cancer. Conclusions The presented preliminary data set could serve as a cost-effective basis for a North Afghan breast cancer registry, with option to extent to a national model. These preliminary data are transformed in profiles of breast diseases, which are used by the local physicians in charge of breast disease patients. Each new case can be compared by the local treating physician with the profile of all preceded cases with the same diagnosis.

Abstract
OBJECTIVES Since neuropathologic diagnosis in the developing world is hampered by limitations in technical infrastructure, trained laboratory personnel, and subspecialty-trained pathologists, the use of telepathology for diagnostic support, second-opinion consultations, and ongoing training holds promise as a means of addressing these challenges. This study aims to assess the utility of static teleneuropathology in improving neuropathologic diagnoses in low- and middle-income countries. METHODS Consecutive neurosurgical biopsy and resection specimens obtained at Muhimbili National Hospital in Tanzania between July 1, 2018, and June 30, 2019, were selected for retrospective, blinded static-image neuropathologic review followed by on-site review by an expert neuropathologist. RESULTS A total of 75 neuropathologic cases were reviewed. The agreement of static images and on-site glass diagnosis was 71% with strict criteria and 88% with less stringent criteria. This represents an overall improvement in diagnostic accuracy from 36% by general pathologists to 71% by a neuropathologist using static telepathology (or from 76% to 88% with less stringent criteria). CONCLUSIONS Telepathology offers a promising means of providing diagnostic support, second-opinion consultations, and ongoing training to pathologists practicing in resource-limited countries. Moreover, static digital teleneuropathology is an uncomplicated, cost-effective, and reliable way to achieve these goals.

[PMID: 32787833 PMCID: PMC7477836 DOI: 10.1186/s12911-020-01170-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Accepted: 06/26/2020] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Growing demand for medical services has increased patient waiting time due to the limited number or unbalanced distribution of healthcare centers. Healthcare teleconsultation networks are one of the potentially powerful systems to overcome this problem. Medical pathology can hugely benefit from teleconsultation networks because having second opinions is precious for many cases; however, resource planning (i.e., assignment and distribution of pathology consultation requests) is challenging due to bulky medical images of patients. This results in high setup and operational costs. The aim of this study is to design an optimal teleconsultation network for pathology labs under the supervision of medical sciences universities in Tehran, Iran. METHODS To avoid the setup cost, we first propose a modified hybrid peer-to-peer (P2P) overlay architecture for our telepathology network, using Iran's National Healthcare Information Network (SHAMS) as the underlying infrastructure. Then we apply optimization techniques to solve the request assignment and distribution problems in the network. Finally, we present a novel mathematical model with the objective of minimizing the variable operational costs of the system. RESULTS The efficiency of the proposed method was evaluated by a set of practical-sized network instances simulated based on the characteristics of SHAMS. The results show that the presented model and architecture can obtain optimal solutions for network instances up to 350 nodes, which covers our target network. CONCLUSIONS We believe that the proposed method can be beneficial for designing large-scale medical teleconsultation networks by adjusting the constraints according to the rules and conditions of each country. Our findings showed that teleconsultation networks in countries with strong information technology (IT) infrastructures are under the influence of consultation fees, while in countries with weak IT infrastructure, the transmission costs are more critical. To the best of our knowledge, no research has so far addressed resource planning in medical teleconsultation networks using optimization techniques. Besides, the target network, i.e., pathology labs under the supervision of medical sciences universities in Tehran and the SHAMS network, are discussed for the first time in this work.

Abstract
INTRODUCTION We describe the use of telepathology in countries with restricted resources using two diagnosis assistance systems (Isabel and Memem7) in addition to the diagnoses made by experts in pathology via the iPath-Network. METHODS A total of 156 cases, largely from Afghanistan, were analysed; 18 cases had to be excluded because of poor image quality. RESULTS Of the remaining 138 cases (100%), a responsible physician provided a tentative diagnosis for 61.6% of them. With a diagnosis from a consultant pathologist, it was then possible to make a definite diagnosis in 84.8% of cases on the basis of images taken from hematoxylin and eosin staining sections alone. The use of the diagnosis assistance systems resulted in an ordered list of differential diagnoses in 82.6% (IsabelHealth) and in 74.6% (Memem7) of cases, respectively. Adding morphological terminology reduced the list of possible diagnoses to 52.2% (72 cases, Memem7), but improved their quality. DISCUSSION In summary, diagnosis assistance systems are promising approaches to provide physicians in countries with restricted resources with lists of probable differential diagnoses, thus increasing the plausibility of the diagnosis of the consultant pathologist.

Abstract
International telecytology can improve patient care by increasing access to regional and international expertise in cytopathology. The majority of international telecytology studies published to date have been based on static telepathology platforms. Overall concordance rates for these studies ranged from 71% to 93%. This is comparable to the concordance rates published for other studies comparing diagnoses made by digital still images to reference glass slides, which vary from 80% to 95%. Static telepathology systems are relatively cheap and easy to use, and have the potential to increase access to international experts in developing countries with limited resources. In contrast, resource-rich academic and private medical centers can use whole slide digital imaging (WSI) for telecytology consultation, though few studies have been published addressing this topic. International telepathology consultation services with digital whole slide image capabilities have been established at several academic medical centers including the University of Pittsburgh Medical Center (UPMC) and the University of California at Los Angeles (UCLA), through the UCLA Center for Telepathology and Digital Pathology. In a small series of 20 telecytology cases submitted to UCLA from 2014 to 2017 (10 gynecologic and 10 fine needle aspiration cases), a meaningful diagnosis was rendered for 100% of cases, with 100% concordance between the submitting institution, versus consultation diagnosis provided by UCLA. These limited results are promising, and in the future both WSI and static telecytology consultation may have a place serving clinical needs in different practice settings.

Abstract
Chronic kidney disease (CKD) is an important public health issue that increasingly affects more patients globally and is associated with adverse clinical consequences with huge economic impact. Effective management of patients with CKD requires delivery of kidney care in a primary care setting where possible and at a higher level with a nephrologist when necessary to improve outcomes. In many instances and for various reasons, it is not possible to follow this pathway of care delivery. With improving telecommunication technologies worldwide, it is hoped that increasing utilisation of electronic communication devices can be used to facilitate kidney care to improve the quality of care delivered to patients, especially those who live in remote regions. Kidney care and therefore outcomes for patients with CKD is often compromised due to lack of access to a nephrologist, either because of distance or shortage of nephrologists, high proportion of patients being unaware they have CKD, lack of population screening for early detection of CKD and risk factors and prevention programmes and poor patient adherence and absence of appropriate CKD management strategies. Telenephrology can play a significant role in addressing these factors and therefore can be leveraged to improve CKD outcomes globally, especially in low to middle-income countries. This paper provides an overview on the potential role of telenephrology in enhancing access to and quality of care delivered to patients with CKD to improve outcomes.

Abstract
CONTEXT Telepathology is a particular form of telemedicine that fundamentally alters the way pathology services are delivered. Prior reviews in this area have mostly focused on 2 themes, namely technical feasibility issues and diagnosis accuracy. OBJECTIVES To synthesize the literature on telepathology implementation challenges and broader organizational and societal impacts and to propose a research agenda to guide future efforts in this domain. DATA SOURCES Two complementary databases were systematically searched: MEDLINE (PubMed) and ABI/INFORM (ProQuest). Peer-reviewed articles and conference proceedings were considered. The final sample consisted of 159 papers published between 1992 and 2013. CONCLUSIONS This review highlights the diversity of telepathology networks and the importance of considering these distinctions when interpreting research findings. Various network structures are associated with different benefits. Although the dominant rationale in single-site projects is financial, larger centralized and decentralized telepathology networks are targeting a more diverse set of benefits, including extending access to pathology to a whole region, achieving substantial economies of scale in workforce and equipment, and improving quality by standardizing care. Importantly, our synthesis reveals that the nature and scale of encountered implementation challenges also varies depending on the network structure. In smaller telepathology networks, organizational concerns are less prominent, and implementers are more focused on usability issues. As the network scope widens, organizational and legal issues gain prominence.

Abstract
Innovative technologies for digital imaging and telecommunications are changing the way we deliver health care. Telepathology collaborations are one example of how delivering remote pathology services to patients can benefit from leveraging this change. Over the years, several academic and commercial teleconsultation networks have been established. Herein, we review the landscape of these international telepathology efforts and highlight key supportive factors and potential barriers to successful cross-border collaborations. Important features of successful international telepathology programs include efficient workflows, dedicated information technology staff, continuous maintenance, financial incentives, ensuring that all involved stakeholders are satisfied, and value-added clinical benefit to patient care. Factors that plague such telepathology operations include legal/regulatory issues, sustainability, and cultural and environmental issues. Pathologists, vendors and laboratory accreditation agencies will need to embrace and capitalize on this new paradigm of international telepathology accordingly.

Abstract
BACKGROUND Telepathology is increasingly being employed to support diagnostic consultation services. Prior publications have addressed technology aspects for telepathology, whereas this paper will address the clinical telepathology experience of KingMed Diagnostics, the largest independent pathology medical laboratory in China. Beginning in 2012 the University of Pittsburgh Medical Center (UPMC) and KingMed Diagnostics partnered to establish an international telepathology consultation service. MATERIALS AND METHODS This is a retrospective study that summarizes the telepathology experience and diagnostic consultation results between UPMC and KingMed over a period of 3 years from January 2012 to December 2014. RESULTS A total of 1561 cases were submitted for telepathology consultation including 144 cases in 2012, 614 cases in 2013, and 803 in 2014. Most of the cases (61.4%) submitted were referred by pathologists, 36.9% by clinicians, and 1.7% by patients in China. Hematopathology received the most cases (23.7%), followed by bone/soft tissue (21.0%) and gynecologic/breast (20.2%) subspecialties. Average turnaround time (TAT) per case was 5.4 days, which decreased from 6.8 days in 2012 to 5.0 days in 2014. Immunostains were required for most of the cases. For some difficult cases, more than one round of immunostains was needed, which extended the TAT. Among 855 cases (54.7%) where a primary diagnosis or impression was provided by the referring local hospitals in China, the final diagnoses rendered by UPMC pathologists were identical in 25.6% of cases and significantly modified (treatment plan altered) in 50.8% of cases. CONCLUSION These results indicate that international telepathology consultation can significantly improve patient care by facilitating access to pathology expertise. The success of this international digital consultation service was dependent on strong commitment and support from leadership, information technology expertise, and dedicated pathologists who understood the language and culture on both sides. Lack of clinical information, missing gross pathology descriptions, and insufficient tissue sections submitted for evaluation were the main reasons for indefinite diagnoses. The overall experience encourages international telepathology practice for second opinions.

Abstract
Low resource countries often have inadequate healthcare systems that, among other problems, suffer from a severe shortage of local expertise. In fields such as pathology, however, where diagnoses are mainly based on macroscopic and histological images, telemedicine can provide an opportunity to supplement the local capabilities by involving a world-wide network of experts. For this, the local pathologist can upload images to an online platform and then consult with international colleagues via teleconferencing, which can be particularly useful in rare or difficult cases. We present the case of a 12-year-old Afghan boy with benign cystic mesothelioma, an extremely rare benign tumour. Using the online platform IPath, we were able to diagnose the eighth reported case of this rare condition in a child, in collaboration with our colleagues in Afghanistan.

Abstract
OBJECTIVE In this study, the efficiency of telemedical consulting with regard to fine needle aspirates from space-occupying lesions (SOLs) of the liver is investigated for the first time. STUDY DESIGN The study includes fine needle aspirations from 62 patients, 33 with hepatocellular carcinoma (HCC) and 29 with non-hepatic tumors. Using the Internet-based iPath system, the initial pathologist submitted 1-8 images from smears and cell block sections. One consultant assessed the cytological and another one the histological images. Both made their diagnoses independent of each other. A final diagnosis was made by immunochemistry of cell block sections. The cytological images were analyzed retrospectively for the occurrence of the most typical HCC indicators. The number of these indicators was related to the initial diagnoses of the three pathologists, and possible reasons for diagnostic errors were analyzed based on this analysis. RESULTS The accuracy of the preliminary telemedical diagnoses regarding HCC was 82.0% for the cytological images and 87.7% for the histological images. Most of the false diagnoses occurred in tumors with unusual cytological and histological patterns. CONCLUSIONS Telemedical consulting is a valuable tool to obtain a second opinion. However, for improvement of the diagnosis of HCC, supplementary immunochemical tests are necessary.

Abstract
We established a hybrid telepathology network at the Children’s Surgical Centre (CSC) in Cambodia, based on store-and-forward communication using iPATH and videoconferencing using Skype. We retrospectively analysed all data from the CSC stored on the iPATH server and reviewed the patient notes over an 8-month period. Of 115 patients for histopathology diagnosis during the study period, 38 cases were uploaded onto iPATH for further telemedicine discussion. The median number of days it took a specialist, other than the local one, to comment on the case on iPATH was 5 days (range 0–15). In three cases (8%) there was no reply from a specialist on iPATH. During the study period, seven clinical conferences were held, with an average of 6 cases (range 4–7) discussed at each conference. All 38 cases discussed had a final agreed diagnosis and firm management plans were made. Of the 24 cases where proactive management was advised, 17 patients followed through with the recommendations. Although the combination of video consultations and store-and-forward communication has not been used much before in the developing world, it has benefited patient care and outcomes at the CSC.

Abstract
Pathology informatics has evolved to varying levels around the world. The history of pathology informatics in different countries is a tale with many dimensions. At first glance, it is the familiar story of individuals solving problems that arise in their clinical practice to enhance efficiency, better manage (e.g., digitize) laboratory information, as well as exploit emerging information technologies. Under the surface, however, lie powerful resource, regulatory, and societal forces that helped shape our discipline into what it is today. In this monograph, for the first time in the history of our discipline, we collectively perform a global review of the field of pathology informatics. In doing so, we illustrate how general far-reaching trends such as the advent of computers, the Internet and digital imaging have affected pathology informatics in the world at large. Major drivers in the field included the need for pathologists to comply with national standards for health information technology and telepathology applications to meet the scarcity of pathology services and trained people in certain countries. Following trials by a multitude of investigators, not all of them successful, it is apparent that innovation alone did not assure the success of many informatics tools and solutions. Common, ongoing barriers to the widespread adoption of informatics devices include poor information technology infrastructure in undeveloped areas, the cost of technology, and regulatory issues. This review offers a deeper understanding of how pathology informatics historically developed and provides insights into what the promising future might hold.

Abstract
Toxicology is and will be heavily influenced by advances in many scientific disciplines. For toxicologic pathology, particularly relevant are the increasing array of molecular methods providing deeper insights into toxicity pathways, in vivo imaging techniques visualizing toxicodynamics and more powerful computers anticipated to allow (partly) automated morphological diagnoses. It appears unlikely that, in a foreseeable future, animal studies can be replaced by in silico and in vitro studies or longer term in vivo studies by investigations of biomarkers including toxicogenomics of shorter term studies, though the importance of such approaches will continue to increase. In addition to changes based on scientific progress, the work of toxicopathologists is and will be affected by social and financial factors, among them stagnating budgets, globalization, and outsourcing. The number of toxicopathologists in North America, Europe, and the Far East is not expected to grow. Many toxicopathologists will likely spend less time at the microscope but will be more heavily involved in early research activities, imaging, and as generalists with a broad biological understanding in evaluation and management of toxicity. Toxicologic pathology will remain important and is indispensable for validation of new methods, quality assurance of established methods, and for areas without good alternative methods.

Abstract
Telepathology has grown immensely due to rapid advances in information and technology. It has a wide variety of applications especially in the developing world, namely for remote primary diagnosis, specialist referrals, secondary opinions, remote teachings and in research. Basic infrastructure and skilled and experienced staff are the prerequisites for its successful implementation.Socio-economic differences in developing nations result in a chaotic scenario so that, the advanced areas have expertise, while rural and remote areas remain deprived. Telepathology has the potential to bridge this gap.This article discusses how successful use of the internet for telepathology is bridging this gap in developing nations and thereby contributing positively to effective healthcare. Possible constraints to telepathology and some solutions to overcome them are also discussed.

Abstract
Background Telecommunication has matured to a broadly applied tool in diagnostic pathology. Technology and Systems Contemporary with the development of fast electronic communication lines (Integrated digital network services (ISDN), broad band connections, and fibre optics, as well as the digital imaging technology (digital camera), telecommunication in tissue - based diagnosis (telepathology) has matured. Open access (internet) and server - based communication have induced the development of specific medical information platforms, such as iPATH, UICC-TPCC (telepathology consultation centre of the Union International against Cancer), or the Armed Forces Institute of Pathology (AFIP) teleconsultation system. They have been closed, and are subject to be replaced by specific open access forums (Medical Electronic Expert Communication System (MECES) with embedded virtual slide (VS) technology). MECES uses php language, data base driven mySqL architecture, X/L-AMPP infrastructure, and browser friendly W3C conform standards. Experiences The server - based medical communication systems (AFIP, iPATH, UICC-TPCC) have been reported to be a useful and easy to handle tool for expert consultation. Correct sampling and evaluation of transmitted still images by experts reported revealed no or only minor differences to the original images and good practice of the involved experts. β tests with the new generation medical expert consultation systems (MECES) revealed superior results in terms of performance, still image viewing, and system handling, especially as this is closely related to the use of so - called social forums (facebook, youtube, etc.). Benefits and Expectations In addition to the acknowledged advantages of the former established systems (assistance of pathologists working in developing countries, diagnosis confirmation, international information exchange, etc.), the new generation offers additional benefits such as acoustic information transfer, assistance in image screening, VS technology, and teaching in diagnostic sampling, judgement, and verification.

Abstract
We conducted a pilot study to assess the feasibility of telecytology as a diagnostic tool in difficult cases originating from a hospital in East Africa. Forty cytology cases considered difficult by a referring pathologist were posted on a telepathology website. Six pathologists independently assessed the static images. Telecytology diagnoses were compared with the consensus diagnoses made on glass slides and also with the histogical diagnoses when available. The diagnostic agreement of the six pathologists was 71-93% and tended to be higher for pathologists with more experience. Reasons for discordance included poor image quality, presence of diagnostic cells in thick areas of smears, sampling bias and screening errors. The consensus diagnoses agreed with histological diagnoses in all 17 cases in which a biopsy was performed. Diagnostic accuracy rates (i.e. telecytology diagnosis vs. histological diagnosis) for individual pathologists were 65-88%. To ensure diagnostic accuracy both referring and consulting pathologists must have adequate training in cytology, image acquisition and image-based diagnosis and the diagnostic questions of importance must be clearly communicated by the referring pathologist when posting a case.

Abstract
We reviewed our experience with the Tanzanian Telemedicine Network in supporting paediatric care at 40 small, rural hospitals in the country. The network began operating in 2008. Store and forward telemedicine was provided via the open source software iPath. The 33 volunteer consultants were based in several countries, although most of them had practical experience in Tanzania. During the first three years of network operation there were 533 referrals. There were 159 paediatric cases (median age five years). Three paediatric specialists provided most consultations (64%), but other specialists provided recommendations when required. The response time was usually less than two days (median 6 h; inter-quartile range 2-24 h). A precise recommendation was not always provided, but since all consultants had an intimate knowledge of the state of health services in Tanzania, their advice was usually well adapted to the local circumstances of the hospitals. Referral to a higher level of care was recommended in 26 cases (16%). A simple web-based telemedicine system combined with email alerts is feasible in remote locations in Tanzania, even where fast Internet connections are not available.

Abstract
Physician shortages are acute in developing countries, where disease burden is the greatest and resources for health care are very limited. A lack of pathologists in these countries has lead to delays in diagnosis and misdiagnoses that adversely affect patient care and survival. The introduction of telepathology into countries with limited resources for health care is but one of multiple approaches that can be used to alleviate the problem. Telepathology is the electronic transmission of digital images that can be used for education and diagnostic consultation. A basic system consists of a microscope with a mounted digital camera linked to a computer. The ability to produce histologic slides, to repair and maintain equipment, and to provide training are also needed for the successful use of this technology. iPath is a Web-based, open platform, software application which was developed at the University of Basel, Switzerland, for telepathology and which brings together pathologists from around the world to provide telepathology support for diagnostic consultation and provides education to centers with limited resources. The use of virtual-slide technology to provide a digital image of an entire glass slide is another technology for diagnostic consultation and pathology education. This technology requires more costly resources to support it, which may limit its utility in many areas. Telepathology can generate collections of digital images and virtual slides needed for training indigenous pathologists in their countries to become self-sufficient. Thus, the long-term goal of this technology is to improve patient care and survival.

Abstract
In order to cope with increasing demands to supply information to a variety of documentation systems outside pathology, pathologists need to set standards both for the content and the use of the information they generate. Oncological datasets based on a set vocabulary are urgently required for use both in pathology and in further processing. Data elements were defined according to German pathology report guidelines for colorectal cancers in line with ISO 11179 requirements for the relations between data element concepts and value domains, as well as for further formal conditions, which can be exported in XML together with metadata information. Tests on 100 conventionally written diagnoses showed their principal usability and an increasing degree of guideline conformity in diagnoses commensurate with training time. This set of oncological data elements is a valuable checklist tool for pathologists, enabling formatted information export for further use and saving documentation effort.

Abstract
Telemedicine can be defined as the practice of medicine or surgery via telecommunication interposition using technologies which permit the exchange of medical information and the application of medical care at a distance. Geographic separation, logistical problems which impede the delivery of care, extreme climactic conditions, artificial environments, or a combination of these parameters may all influence the health of patients and the ability of healthcare professionals to do their work effectively. This article reviews the standards of current telemedical and telesurgical systems, defines target groups who may benefit from such care, and details the technologic requirements of telemetry; it uses selected cases and a review the medical literature. The conclusion focuses on future developments and the potential for further improvements through ongoing research.

Abstract
BACKGROUND Tissue-based diagnosis or diagnostic surgical pathology is a highly accurate, sensitive and specific medical diagnostic technique that has expanded rapidly in using both molecular biology and computer technology. OBJECTIVE The objective is to analyze the present stage and potential influence of distributed data acquisition, analysis and presentation in tissue-based diagnosis by using recently developed standardized network systems such as grids. METHODS Interpretation of medical data is often based upon specialized examination, visual information acquisition and transfer as well as upon data collected from various sources. Efficient and accurate diagnostics require standardized data and transfer modes, which can be provided by a grid environment. The medical requirements, construction of an adequate grid environment, practical experiences in various medical disciplines and potential use in tissue-based diagnosis are described. CONCLUSIONS Grid technology is probably a useful tool to meet the conditions of tissue-based diagnosis in the near future, and will probably play a significant role in its further development.

Abstract
Background Since 1999, the Swinfen Charitable Trust has operated an email referral system between doctors in the developing world and specialists in the industrialized world. Since 2001, it has expanded its operation into the Middle East, in particular Iraq, an area of considerable conflict. Objectives The aim was to compare referral patterns to the Trust from the Middle East with those received from the rest of the developing world and to look for qualitative evidence of health gain. Methods We analyzed referrals to the Swinfen Charitable Trust between July 2004 and June 2007 and compared these by speciality with those received from elsewhere during the same 3-year period. We asked two referring doctors for their views of the process, and we analyzed the total Middle Eastern referrals made to a single specialty (neurology). Results Between July 2004 and June 2007, 283 referrals were received from four countries in the Middle East (Iraq, Afghanistan, Pakistan, Kuwait) and 500 cases were received from 22 other countries. The 283 cases resulted in 522 separate queries to specialists. The median time to specialist reply for the queries relating to the 283 Middle Eastern cases was 24.3 hours (interquartile range 6.1-63.3). There was a significant difference in case mix between the Middle East and the rest of the world (P < .001), with more obstetric referrals and fewer referrals in medical specialties and radiology. The referring doctors were helped greatly by the service. The neurologist was confident of the diagnosis in 20 of 26 referrals received (77%). Both referring doctors and the specialist were able to cite referred cases where management was improved as a result of the service. Conclusions Email telemedicine can be used in areas of conflict such as the Middle East. Perhaps surprisingly, trauma referrals are not increased but obstetric referrals are. Supporting individual doctor-patient encounters in this way is therefore often beneficial and is easily expandable. As well as improving care for individuals, email telemedicine provides effective case-based learning for local doctors, leading to improved care for subsequent similar patients.

Abstract
Computer-based learning (E-learning) is of increasing importance for the education of students and professionals. Various publicly accessible online courses for cytologists now exist and some of these are presented in this paper. For the learning platform Patho-Basiliensis (http://www.unibas.ch/patho/) we have developed several learning materials: a database of 726 cytology images, a cytopathology course to teach the basics of cytopathology, and a game testing histologic-cytologic correlation. Tests on lung and urinary cytology were attended by 383 international participants. The virtual microscopy technology will revolutionize telecytology and cytology education.

Abstract
The objectives of this paper on the Réseau Afrique Francophone de Télémédecine (RAFT) project are the evaluation of feasibility, potential, problems and risks of an Internet-based tele-medicine network in developing countries of Africa. The RAFT project was started in Western African countries 5 years ago and has now extended to other regions of Africa as well (i.e. Madagascar, Rwanda). A project for the development of a national tele-medicine network in Mali was initiated in 2001, extended to Mauritania in 2002 and to Morocco in 2003. By 2006, a total of nine countries are connected. The entire technical infrastructure is based on Internet technologies for medical distance learning and tele-consultations. The results are a tele-medicine network that has been in productive use for over 5 years and has enabled various collaboration channels, including North-to-South (from Europe to Africa), South-to-South (within Africa), and South-to-North (from Africa to Europe) distance learning and tele-consultations, plus many personal exchanges between the participating hospitals and Universities. It has also unveiled a set of potential problems: (a) the limited importance of North-to-South collaborations when there are major differences in the available resources or the socio-cultural contexts between the collaborating parties; (b) the risk of an induced digital divide if the periphery of the health system in developing countries is not involved in the development of the network; and (c) the need for the development of local medical content management skills. Particularly point (c) is improved through the collaboration between the various countries as professionals from the medical and the computer science field are sharing courses and resources. Personal exchanges between partners in the project are frequent, and several persons received an education at one of the partner Universities. As conclusion, we can say that the identified risks have to be taken into account when designing large-scale tele-medicine projects in developing countries. These problems can be mitigated by fostering South-South collaboration channels, by the use of satellite-based Internet connectivity in remote areas, the appreciation of local knowledge and its publication on-line. The availability of such an infrastructure also facilitates the development of other projects, courses, and local content creation.
