Microcomputer patient database management system for an MRI facility.

A management system for a magnetic resonance imaging facility was developed to store pertinent patient data and to maintain a teaching file. The system was developed on a Digital PRO-350 microcomputer using a commercially available database software package. The cost of the system was about $7000. The patient data are entered at a terminal by a clerk typist. Input data are condensed or abbreviated to accommodate the limited data storage on the microcomputer. Cases can be rapidly retrieved and sorted on the basis of any of the 42 data fields available or any combination of these fields. The system has been successfully used for 18 months to create directories for a teaching file, for presentations, and for clinical research. Census-type data can be compiled, and the system can be used for word processing.

Profiling self-monitored blood glucose results with the personal microcomputer.

Personal microcomputers are becoming available to millions of individuals. Inevitably this new technology will be applied in a variety of ways to the routine management of diabetes. In this article we present the results of a pilot effort which shows that large cumbersome sets of blood glucose data, obtained by conventional self-monitoring techniques, can be stored, analyzed, and displayed conveniently with a home microcomputer. This technique has potential value for the identification of long-term trends in blood glucose regulation.

A comprehensive microcomputer network program for histopathology.

For a small hospital with a limited budget, a stand-alone histopathology microcomputer network may be more valuable to the pathologist than one running off the hospital's main computer. In return for sacrificing the limited benefit of screen reading of pathology reports in the wards, one receives the great advantage of more rapid retrieval of disease data. Commercial relational database programs for microcomputers can now achieve nearly all the power of a minicomputer program, with more versatility. Using an application developed on such software, we now have 30,000 pathology reports entered, from which we can retrieve a list of pathology numbers, with patients' names, age, sex, disease, and site, for any diagnosis in 3-5 seconds. The application includes full biopsy reports for doctors and wards, autopsy final diagnoses, computer-assisted Snomed coding, outside consultations, literature abstracts, daybook printing, workload statistics and billing codes and charges, and a cytology module has been added for another hospital. Moreover, the interested pathologist can easily make his own alterations to menus, entry screens, fields, and screen listing or printout formats.

Microcomputer-based cardiac pacemaker-control system through blood temperature.

A microcomputer-based temperature-sensitive cardiac pacemaker system and some preliminary experiments are described. The system consists of a microcomputer, a twin 5 in floppy disk unit, expansion and interface units, a visual display unit and a printer. It senses the blood temperature in the right atrium, determines the pacing rate and supplies the heart with stimulating pulses. System-heart interfacing is performed by the separate pacing and sensing units which communicate with the computer via a peripheral interface IC in an expansion unit. The pacing rate is determined by software, rather than a combination of hardware elements. The temperature response time of the system, from 25 degrees C to 40 degrees C is about 26 s, and this would seem to be satisfactory given that smaller and slower changes in blood temperature are normal.

Telemetry system for heart-rate and blood temperature using a microcomputer.

A radio-telemetry system using a microcomputer has been constructed to measure both the heart-rate (HR) and right atrial blood-temperature in dogs. The telemeter incorporates a thermistor temperature probe, which allows blood-temperature measurements in the range of 35 degrees-42 degrees C with an available resolution of +/- 0.02 degree C. The output of the receiver is connected to active filters, a frequency counter and an HR meter, and finally to a microcomputer, through an appropriate interface circuit, for data linearization and storage.

A microcomputer system for analysis of coronary artery calibre and blood flow.

Measurement of myocardial blood flow and assessment of coronary calibre in man has important clinical and research value. An inexpensive microcomputer system has been developed to facilitate analysis of each of these. Coronary sinus and great cardiac vein blood flow are measured using the thermodilution technique. The output of the temperature measurement circuitry is digitized and used to calculate blood flows. For coronary artery calibre measurement, the outline of an arterial segment recorded during coronary arteriography is digitized manually. The microcomputer system provides a graphic display of the digitized artery and calculates diameters throughout its length. Excellent correlations were observed between computer and manual methods for both systems.

A microcomputer keyboard substitute for the disabled.

A microcomputer keyboard substitute for use by the disabled is described. The system displays the characters of a standard keyboard as a matrix where each character is enunciated by an LED. The matrix of characters is scanned by two simple switches until the desired character is reached. This is then entered into the computer using one of the two switches. The system is designed for use on the BBC Model B microcomputer but is relatively easily adapted for use on other machines. It operates in parallel with the conventional keyboard and does not depend on additional system software. It does not use any of the standard computer interfaces, and the character grid can be changed to suit the needs of a particular user.

Applications of a microcomputer-based reconstruction system to produce realistic three-dimensional shaded images from serial sections.

A microcomputer-based system is described that generates three-dimensional shaded images from serial section data. It is implemented on the IBM PC-AT microcomputer, using a graphics display card (Real World Graphics PC 4000) to provide sufficient colours for the production of realistically shaded and highlighted images. Image generation time is typically less than 10 min. The capabilities of the system are illustrated by reconstructions of the Kurloff cell from the guinea-pig (based on serial electron micrographs), human teeth (based on light microscope data), the human leg (from gross anatomical sections) and the human brainstem (from stereotaxic atlas data). The system is applicable to a wide variety of serial section data from histological, anatomical and medical imaging systems and ultrastructural studies.

[Microcomputer control of a LED stimulus display device].

A visual stimulus display system controlled by a microcomputer was constructed at low cost. The system consists of a LED stimulus display device, a microcomputer, two interface boards, a pointing device (a "mouse") and two kinds of software. The first software package is written in BASIC. Its functions are: to construct stimulus patterns using the mouse, to construct letter patterns (alphabet, digit, symbols and Japanese letters--kanji, hiragana, katakana), to modify the patterns, to store the patterns on a floppy disc, to translate the patterns into integer data which are used to display the patterns in the second software. The second software package, written in BASIC and machine language, controls display of a sequence of stimulus patterns in predetermined time schedules in visual experiments.

Incidence of symptomatic mild hypoglycaemic events: a prospective study in adult patients with insulin-treated diabetes mellitus using a portable microcomputer-based data-logger.

A new method for recording mild symptomatic hypoglycaemic events was evaluated. A pilot study was conducted using a portable microcomputer-based data-logger which was carried for 10 days by 38 adult patients with insulin-treated diabetes mellitus. The patients recorded symptomatic hypoglycaemic events, meals and sleeping-hours. The recording was prospective and continuous and did not allow any corrections afterwards. No patients had any problems in carrying or handling the data-logger and compliance was good. A total of 76 hypoglycaemic events were recorded in 29 patients. Two patients had hypoglycaemic events that they were unable to manage without help from another person. There was a peak in the incidence of hypoglycaemic events late postprandially, particularly in patients treated with a four-dose insulin regime with fast-acting insulin before meals. A portable microcomputer-based data-logger is a reliable new method for recording symptomatic mild hypoglycaemic events. The incidence of mild hypoglycaemic events was higher than previously reported.

A microcomputer system for assessment of peripheral blood flow. An example of nasal blood flow.

We have designed and implemented a microcomputer system for studying the effect of various mediator substances on the nasal blood flow. The system uses an IBM PC/AT microcomputer, which is connected with a Laser Doppler Flowmeter (LDF) and an iontophoretic drug application system. The LDF measures flux from the tissue that in the example is the inferior nasal turbinate. The flux is converted to digital form by an analog-digital converter of 12 bits. The program is implemented in the Pascal language. In the analysis, a flux level, amplitude, rise time and decay time of the pulse wave are determined. The effect of drugs on the flux can be studied by applying them iontophoretically. In the program the length and number of the drug application periods as well as the recording period are user-driven. In the nasal blood flow iontophoretically administered adrenaline reduced significantly the flux parameters and histamine canceled this effect. Tachyphylalaxis was a frequent observation in repeated measurements. The system can be used to evaluate the role of different transmitters in the etiology of chronic rhinitis.

Application of a small microcomputer to cell image analysis.

Solutions to three problems in using small microcomputers for interactive cell image analysis are discussed. (1) To allow interactive processing of up to 62 X 88 pixels on inexpensive screens, data can be displayed in gray levels with an approximate logarithmic grading. Each pixel is composed of 32 screen coordinates, applying the dither matrix method to avoid artificial structures. (2) To mark special regions of interest in the image, a graphic cursor, handled from the keyboard, was implemented. (3) To evaluate parts of the image, as outlined by the cursor, the program must distinguish whether a particular pixel is outside, inside or on the border of the region. The developed algorithms permit practical interactive evaluation of cell images on a small microcomputer, with no image analysis implementation. However, it is necessary that the assembly language of the microprocessor be available for some sophisticated programming and that the operating system support graphic facilities with an appropriate resolution.

[A clinical trial of microcomputer software for calculation of aminophylline dosages].

I made microcomputer software for the pharmacokinetic calculation of appropriate administration doses of aminophylline for the treatment of status asthmaticus. It consists of three programs for determination of initial doses, four for determination of maintenance doses, and four for calculation of the pharmacokinetics parameters (Vd, Ke, CL, T1/2). The parameters were estimated 376 times during 151 attacks in 84 patients with bronchial asthma. Vd, Ke, and CL were calculated as below, and the wide variation in the values suggests that individual programs for theophylline therapy should be made for each patient. I concluded that these microcomputer programs were useful in creating an individual administration program. Distribution volume (Vd): 385 +/- 106 ml/kg (n = 115) Elimination rate constant (Ke): 0.155 +/- 0.0878/h (n = 176) Clearance (CL): 61.8 +/- 14.3 ml/kg.h (n = 85)
