"Medical informatics in a medical research facility. An interactive multimedia presentation". Diabetes as a model.

This interactive demonstration provides a model for integrating information in a medical facility. By the use of networking computers, diagnostic data and scientific data are shared between geographically-separated clinical and research units. Data collected in a patient database in the outpatient clinic is sorted on specified qualifying criteria and the resulting subset further analyzed for research studies. To show the process of patient selection from a general database to a diabetes database, and further selection to a subset of diabetes, i.e., Diabetic Neuropathy, the authors used HyperCard. Firstly, HyperCard provided us with a flexible design allowing for both vertical and horizontal progressions. Because we wanted to include an educational component on diabetes and its complications, this flexibility was important. At any point in the demonstration, the viewer is able to access more information nested in several levels. Secondly, we wanted to be able to import a variety of programs that are used to translate diagnostic data into scientific data that is analyzed and prepared for publication in a medical textbook or journal. According to Douglas Adams, author of "Pathways and Relationships", HyperCard occupies the same niche in the evolution of software as human beings do in the evolution of life. "It's the fact that we are unspecialized but infinitely adaptable that has been our success as a species. In the same way, HyperCard is unspecialized but can turn its hand to any kind of task. And if the task is beyond it, HyperCard can use the phone, go for a ride on Excel, or go out and find a powerful graphics tool or sophisticated wordprocessing program!"

Medical Practice Support System. A medical practitioner's multimedia workstation.

The United States Navy has developed a computer based Medical Practice Support System (MEPSS) intended for use by medical practitioners working in isolated situations. The system, now being tested in operational settings, emphasizes inexpensive, easily obtained off-the-shelf hardware and specially developed, readily implemented software to provide users with: 1) medical record keeping, 2) an electronic medical library, 3) interactive video instruction programs suitable for continuing medical education, 4) computer based medical diagnosis and treatment assistance, and 5) electronic communications with other facilities. This demonstration emphasizes a user based developmental approach, integration of diverse systems under a single user interface, and portable hardware. The resulting system makes medical information needed by practitioners instantly available at the time of a patient encounter, whenever and wherever that encounter may occur. Making clinically valuable information immediately available, MEPSS demonstrates how practitioners can use computers to help their own efforts to improve patient care quality and efficiency.

Hexachlorobenzene levels in multimedia environmental samples from selected chemical production plants.

A sampling and analysis program was conducted to determine hexachlorobenzene (HCB) levels in air, water, soil and sediment. Nine industrial plants were selected, representing six major industries: perchloroethylene, trichloroethylene, carbon tetrachloride, chlorine, triazine herbicides and pentachloronitrobenzene. Of the six industries sampled, higher concentrations of HCB were associated with the production of perchloroethylene, trichloroethylene and carbon tetrachloride. In the one plant that produced only carbon tetrachloride, HCB levels were quite low. HCB concentrations were relatively high in samples from the pentachloronitrobenzene plant, i.e., low microgram/m3 range in air and generally over 100 micrograms/g along roads within the plant. Very low levels of HCB were associated with plants producing chlorine and triazine herbicides. Several different waste-disposal methods were used at the perchloro- and trichloroethylene plants that were sampled. The highest level of HCB was detected in air and soil at the plant using on-site landfill and open-pit storage. High HCB levels were detected in loading and transfer areas at plants using off-site disposal methods. Lower HCB levels were found at plants using on-site incineration, but downwind air concentrations were elevated above background at these plants. Production of perchloro- and trichloroethylene by low-temperature oxychlorination and incineration of liquid bottom wastes resulted in high levels (micrograms/m3) of HCB in the air but relatively low levels in the effluent water.(ABSTRACT TRUNCATED AT 250 WORDS)
