We present two approaches for pre-processing and indexing of the open-access PubMed articles, and four methods for query construction which are applied to the previous two approaches. Regarding pre-processing, our main assumption is that only particular medical study designs are appropriate for each type of clinical question and we filter the number of articles in each clinical question type. Regarding query construction, our main idea is to detect the medical concepts in the medical cases and to expand them with terms of semantic controlled vocabularies (such as UMLS). The track evaluation shows that our approaches provide comparable results with the other participants’ approaches without to conclude on safe findings.

The purpose of the study is to develop a web-based system communicating with PACS, for extracting information from stored SR documents for educational and research purposes. MATERIAL / METHODS: This system consists of an interface communicating with PACS, made up of web service technologies. The interface extracts data from SR documents stored in the PACS and stores them in a local database of the system. The system database is administrated from an easy to use web user interface which enables viewing and analyzing the data, creating new SR documents for a study anf offering full archiving capabilities. RESULTS: The proposed system gave the opportunity to add medical reports in a study, using web user interface. The stored reports in the system could be transferred towards PACS in the format of DICOM SR and ...

Methods and Materials: During the past years web-based applications have enabled users to access DICOM image servers through the Web. The next step is to deploy healthcare specific Web Services that allow applications (as opposed to users) to exchange information and data through standardized web technologies. We have employed SOAP (Simple Object Access Protocol), XML (eXtensible Markup Language) and the related web technologies to create a Web Service permitting query of different DICOM servers. The system transforms SOAP/XML queries into DICOM protocol, communicates with the conventional server using the DICOM protocol, and transforms the results back into an XML document, encapsulated in SOAP. Results: Any conventional DICOM source can use the proposed Web Service to expose the principal DICOM operations of store, query, and retrieve over the Web, using XML documents communicated via SOAP messages. The WSDL (Web Services Description Language) document allows other web-service enabled applications to seamlessly invoke any of the methods exposed. For demonstration purposes, a web-based application has been created for accessing our Web Service via a web browser. Conclusion: The proposed Web Service interface can support integration of conventional DICOM sources through general purpose web technologies with other web-service enabled applications such as authoring tools, general purpose image processing environments, and clinical web servers.

DIPE integrates existing and new image processing software and employs sophisticated execution scheduling mechanisms for the efficient management of computational resources within a distributed environment. It can also be extended to provide various added-value services, such as management and retrieval of image processing software modules, as well as advanced charging procedures based on quality of service. DIPE can be viewed as the natural evolution of the legacy field of medical image processing towards a service over the emergent health care telematics networks.

In this paper, we present an overall analysis of eHealth topics and trends in published literature indexed in PubMed (all records till 31 Dec 2016, search on 25 Jan 2017), based on unsupervised topics modeling and trends analysis. Overall the analysis indicates a slightly declining (non significant) publication trend when compared to the overall PubMed corpus growth. Within the area of eHealth, a high negative trend is found for topics related to applications that support medical expert collaboration and consultation (e.g. teleradiology, image transmission, telesurgery, consultation between centres). On the contrary, a high positive trend is found for topics related to personalized eHealth applications, including mobile devices and patient empowerment.
