Cellular Radio Telecommunication for Health Care: Benefits and Risks

Cellular radio telecommunication has increased exponentially with many applications to health care reported. The authors attempt to summarize published applications with demonstrated effect on health care, review briefly the rapid evolution of hardware and software standards, explain current limitations and future potential of data quality and security, and discuss issues of safety

Objective: Large databases of published medical research can support clinical decision making by providing physicians with the best available evidence. The time required to obtain optimal results from these databases using traditional systems often makes accessing the databases impractical for clinicians. This paper explores whether a hybrid approach of augmenting traditional information retrieval with knowledge-based methods facilitates finding practical clinical advice in the research literature. Design: Three experimental systems were evaluated for their ability to find MEDLINE ® citations providing answers to clinical questions of different complexity. The systems (SemRep, Essie, and CQA-1.0), which rely on domain knowledge and semantic processing to a varying extent, were evaluated separately and in combination. Fifteen therapy and prevention questions in three categories (general questions, intermediate, and specific) were searched. The first ten citations retrieved by each system were randomized, anonymized, and evaluated on a three-point scale. The reasons for ratings were documented

Using UMLS metathesaurus concepts to describe medical images: dermatology vocabulary

Web servers at the National Library of Medicine (NLM) displayed images of ten skin lesions to practicing dermatologists and provided an online form for capturing text they used to describe the pictures. The terms were submitted to the UMLS Metathesaurus (Meta). Concepts retrieved, their semantic types, definitions and synonyms, were returned to each subject in a second web-based form. Subjects rated the concepts against their own descriptive terms. They submitted 825 terms, 346 of which were unique and 300 mapped to UMLS concepts. The dermatologists rated 295 concepts as ‘Exact Match’ and they accomplished both tasks in about 30 min
