Implant provision of key,pinch and power grips in a C6 tetraplegic

An 11-channel multiplexed stimulator of nerves and muscles in the left forearm was implanted for hand control in January 1986 in a 21 year old woman who, after sustaining a C6 spinal lesion 7 years earlier, had voluntary shoulder and elbow movement but paralysed hands, trunk and legs. The patient controls the stimulation via a microcomputer control box and an RF transdermal link. We have investigated the control of her stimulated hand with a joystick under her contralateral hand which she moves from the shoulder and elbow. Since 1986, we have tried a variety of joystick control schemes involving power and key grips. Currently, for grip adjustment, forward and backward joystick movements correspond to thumb extension and abduction, respectively giving in addition both finger and wrist extension, whereas right and left joystick movements yield first closure and thumb opposition/adduction and flexion, respectively. Useful grasps are available by moving the joystick forward and then left (key grip), by moving the joystick backward and left (pinch grip), or by moving the joystick back and right (power grip). Thus, three distinct grips may be selected using these three quadrants of joystick movement. An additional control mode was found to be desirable to augment the patient's limited voluntary wrist positioning and provide wrist stability while adjusting finger grip.

Computer assessment of life-style in a gastroenterology clinic

To examine the potential benefit of a computer-assisted interview about life-style in gastroenterology practice, 34 consecutive patients attending a gastroenterology clinic were questioned by a computer using software designed to obtain a comprehensive history of alcohol, caffeine, cigarette, and illicit drug use, together with an assessment of exercise, sexual activity, and nutrition. Comparisons of the information obtained by the computer with clinical records revealed that physicians documented only 3% of the patients as problem drinkers, 3% as caffeine abusers, and 17% as smokers, whereas the computer identified 10% of the patients as problem drinkers, 27% as caffeine abusers, and 43% as smokers. These findings imply that patients may be more apt to tell more about adverse life-style to the computer than to a physician during clinical interview. In a sample patient population from a gastroenterology clinic, a microcomputer provides an acceptable, efficient, and potentially cost-effective way to assess life-style.     

Microcomputer-assisted transmission of disaster data by cellular telephone

Voice communication of information during disasters is often inadequate. In particular, simultaneous transmission by multiple callers on the same frequency can result in blocked transmissions and miscommunications. In contrast, nonvoice transmission of data requires less time than does voice communication of the same data, and may be more accurate. We conducted a pilot study to test the feasibility of a microcomputer assisted communication (MAC) network linking the disaster scene and the command hospital. The radio chosen to transmit data from the field disaster site to the command hospital was a cellular telephone connected to the microcomputer by modem. Typed communications between the microcomputer operators enabled dialogue between the disaster site and the hospitals. A computer program using commercially available software (Symphony by Lotus, Inc.) was written to allow for data entry, data transmission, and reports. Patient data, including age, sex, severity of injury, identification number, major injuries, and hospital destination were successfully transmitted from the disaster site command post to the command hospital. This pilot test demonstrated the potential applicability of MAC for facilitating transmission of patient data during a disaster.

Estimation of the signal generating value of spontaneous reports of adverse reactions

The main function of drug adverse reaction spontaneous reporting systems is the generation of early signals of previously undocumented serious reactions to recently marketed products. To quantify the signal generating value of case reports we first score them on a 6-level causality/completeness scale combining the French and the European community assessment methods; prior documentation is scored on a 5-level scale inspired from the French method. Then the prior documentation value is subtracted from the imputability value and the resulting difference is considered as a signal generating value. The result is a scale of ranks ranging from 1 to 10, averaging 4.8 in the database of our regional program. It may serve to compare the usefulness of spontaneous reports originating from different sources and it may encourage clinicans to submit more informative case reports.
