Cephalometric analysis and data display simplified for clinical use.

A review of the literature on cephalometrics was undertaken with the aim of clarifying the multiplicity of definitions of planes in common use and establishing a simple analysis for clinical purposes which uses the minimum number of planes and angles and yet utilises points of maximum accuracy of identification and good reproducibility. It is hoped that the outcome of this review may be of practical value to orthodontic clinicians.

An improved data display system for fetal heart rate monitoring.

Fetal heart rate (FHR) monitor records, particularly those derived from external sensors, may contain artifactual information closely resembling true FHR patterns. Additional machine-determined information may be used to help discriminate these data. Present commercial systems for indicating potentially artifactual FHR modify the FHR display, and this tends to cause the physician to ignore the absence of data or annoy him by obliterating some useful as well as potentialy useless information. Therefore, we chose to put the information that the data may be artifactual on another channel and allow the physician, rather than the instrument, to modify the interpretation of the FHR as necessary. A computer study was made of the characteristics of FHR beat-to-beat changes during poor signal to determine the most appropriate criteria for indicating when the FHR record is highly likely to be artifactual. Unphysiologic, erratic FHR changes are easily flagged by the presence of 3 serial beat-to-beat changes greater than 25 beats/min. Clinical testing demonstrated that this system allows the physician to better discriminate between valid and invalid data and increases the amount of usable data, particularly in active patients.

Central station data displays: an experimental evaluation of observer performance. Part 1: Number of displays and observation time.

16 experienced ICU nurses monitored simulated central station VDU displays for the occurrence of ectopic beats and for signs of deterioration in general cardiovascular status. Each period of monitoring lasted for 1 h, and on separate occasions each nurse monitored 1, 2, 4 or 6 displays simultaneously. As the number of observed screens increased, performance declined significantly, with reduced identifications of discrete events (e.g., ectopic beat detections), and with increased delays in determining a deterioration in cardiovascular status; in addition, a secondary task was less accurately and efficiently performed, and the nurses tended to become increasingly fatigued. Efficient observing was maintained over the 1 h monitoring period, but only at considerable cost in terms of fatigue and a loss of alertness. The results suggest that there may be restrictions in the use of complex central station facilities at first-line observation posts for patient care.

Statistical search space reduction and two-dimensional data display approaches for UPLC-MS in biomarker discovery and pathway analysis.

A new analytical strategy for biomarker recovery from directly coupled ultra-performance liquid chromatography time-of-flight mass spectrometry (UPLC Tof MS) data on biofluids is presented and exemplified using a study on hydrazine-induced liver toxicity. A key step in the strategy involves a novel procedure for reducing the spectroscopic search space by differential analysis of cohorts of normal and pathological samples using an orthogonal projection to latent structures discriminant analysis (O-PLS-DA). This efficiently sorts principal discriminators of toxicity from the background of thousands of metabolic features commonly observed in data sets generated by UPLC-MS analysis of biological fluids and is thus a powerful tool for biomarker discovery.

Physiological data display during anaesthesia.

It is difficult to chart more than three or four physiological parameters on one graph without causing confusion because of multiple symbols, crossing lines or different scales. A method of charting multiple parameters simultaneously is described which minimises this confusion and can, at a glance, inform the user of the acceptability of the results.

Computers in anesthesiology and intensive care. User attitudes to a real-time patient data display system.

Wythenshawe Hospital is a large district general hospital, with an important Cardio-Thoracic department. A developed DNTRODUCED into this area and its attendent laboratories two years ago. Six months after hardware commissioning the system was fully operational throughout the whole department and during the past two years most of the additional user requirements, including calculations, have been met. This paper describes the attitudes and acceptance by doctors, nurses, laboratory and para-medical staff to the concept of recording all patients clinical information within this environment, via a computer system. Staff considered that both input and retrieval of information had been improved by computer assistance, and telephone call within the department had been reduced. Nurses and technicians prefered computer assistance to the old system of manual record keeping, but clinicians appeared less decided. However, all groups trusted the computer.

[Changes in visual function caused by work at a data display terminal].

Working at video display terminals (VDTs) is particularly demanding in terms of orthopaedic and visual functions. This study was initiated to examine whether, and if so how, VDT work can influence the visual system. It was designed as a 5-year-prospective study based on the matched-pairs technique. The subjects were examined at the beginning and after 5 years of VDT work. The study group consisted of 102 people working at VDTs, and these were paired with 102 other office workers who did not use VDTs. The legally prescribed screening examinations of visual acuity (distance and near vision, phorias, stereopsis, and colour vision) were carried out. We also checked the anterior segments by examination with the slit-lamp and the fundus by ophthalmoscopy. Break-up time, Schirmer-I test, perimetry and tonometry were included in our range of examinations. We found a significant difference in asthenopia and daily hours of VDT work between VDT workers working less than 6 h daily and those working more than 6 h daily. In the study group pre-existing exophoria seemed to increase, but no statistical significance was found on testing. Nor was there any significant difference between the study group and the control group in the parameters examined in the course of the screening examination. In our investigation of monocular VDT workers (n = 3) we could not find any visual problems.

Interpretation of pathophysiology by laboratory data (2). Graphic display of data, dynamic pattern.

In order to display the pathophysiology of a patient more efficiently and adequately than in the static radar chart presented in the first report, a dynamic radar chart and serial line graphs using colored lines were presented. A dynamic radar chart prepared as described particularly in this report, shows the whole data of a patient along with the time course of illness by the space-saving "overlapped-drawing". Moreover serial line graphs are employed for items important for the understanding of a patient's pathophysiology or for items which show obscure change due to overlapping in the dynamic radar chart. Although this line graph is space-occupying it reveals more clearly the changes of data throughout the entire course of a patient's disease. In this second report the dynamic presentation of data and its interpretation, were presented for nine cases. This was done more efficiently and adequately than in the cases described in the first report where the display and interpretation of pathophysiology of a patient was made using merely the data of a single point.

Interpretation of pathophysiology by laboratory data (1). Graphic display of data, static pattern.

We have been performing the following studies over the past several years: 1) Conversion of the data of blood chemistry to a standard deviation index (SDI) as a common scale to offset differences due to measuring conditions. 2) Static global display of all the various SDI values at a single time-point on a radar chart for each patient (static radar chart). 3) Dynamic display of the pathophysiology of each patient by a radar chart (dynamic radar chart), and by a serial line graph using colors. 4) Automatic, quantitative and objective interpretation of the pathophysiology of each patient with our program at an adequate time-point selected on the dynamic display graphs. 5) Scrutiny of the interpreted results in comparison with the clinical course and data for other examinations. The present report includes details of 1), and 2).

Human performance evaluation of a metaphor graphic display for respiratory data.

Metaphor graphics are data displays designed to look like corresponding variables in the real world, but in a non-literal sense of "look like". Evaluation of the impact of these graphics on human problem solving has twice been carried out, but with conflicting results. The present experiment attempted to clarify the discrepancies between these findings by using a complex task in which expert subjects interpreted respiratory data. The metaphor graphic display led to interpretations twice as fast as a tabular (flowsheet) format, suggesting that conflict between earlier studies is due either to differences in training or to differences in goodness of metaphor. Findings to date indicate that metaphor graphics work with complex as well as simple data sets, pattern detection as well as single number reporting tasks, and with expert as well as novice subjects.

A fast microcomputer language for signal acquisition, processing and display.

Data Acquisition and Display (DAD) language was designed to facilitate the application of 8080- and Z80-based microcomputers to problems involving signal acquisition, processing and display. DAD supports instructions that are similar to those BASIC but also has instructions found in the structured programming languages. Implemented as an interactive compiler and designed around a hardware arithmetic processing unit interfaced to the S100 bus, DAD executes its instructions considerably faster than most high-level languages. DAD supports floating point, double-precision integer and an additional single-byte-integer data structure for the acquisition and processing of 8-bit resolution data. DAD interfaces with peripherals that use the unsigned-magnitude or 2'-s-complement data format. A hardware programmable interval timer supplies accurate timing for many of DAD's instructions. DAD operates under and relies upon the CP/M operating system for its console and disk file input/output.
