The gene responsible for hereditary hemochromatosis has been shown to be closely linked to the HLA-A and D6S105 loci on the short arm of chromosome 6. Efforts at mapping the disease gene have been hindered, however, by a lack of informative recombinants in this region. We have identified two recombinant individuals in a single affected family and have(More)

A 5-year-old boy was shown cartoons, and punished for thumbsucking during alternate cartoons by turning off the cartoons for as long as his thumb remained in his mouth. Thumbsucking weakened during such periods. During alternate periods of uninterrupted cartoons, thumbsucking promptly recovered, suggesting a quick discrimination process. Two other(More)
This research demonstrated some of the conditions under which retarded children can be taught to imitate the actions of adults. Before the experiment, the subjects were without spontaneous imitative behavior, either vocal or motor. Each subject was taught, with food as reinforcement, a series of responses identical to responses demonstrated by an(More)
BACKGROUND The prothrombin time (PT) test, which is the most common coagulation test used in the outpatient setting, has not been recommended for office laboratory use because it has been technically difficult to perform. Consequently, serious errors in patient care could occur because of an erroneous result. The Coumatrak (E.I. Du Pont, Wilmington, Del)(More)
New developments in laboratory technology have produced complex analytic systems that are simple to operate, relatively reliable, and inexpensive. These systems allow the office practitioner to perform test analyses in an office laboratory and can provide timely information useful for diagnostic and clinical management decisions.

The Kodak DT-60 tabletop chemistry analyzer was evaluated with standardized protocols to determine the system's precision and accuracy when operated by four volunteers (a secretary, a licensed practical nurse, and two family medicine residents) in a simulated office laboratory. The variability of the results was found to be significantly greater than the(More)
The accuracy and precision of the Kodak DT-60 tabletop chemistry analyzer were evaluated in the clinical laboratory at the Portland (Ore) Veterans Administration Medical Center, and its operational throughout and cost were estimated. All DT-60 tests that were studied exhibited clinically acceptable precision and, except for the glucose method, accuracy. The(More)
The scope and magnitude of bedside testing by personnel without formal laboratory training have recently increased. There has been some question about the reliability of bedside test results produced by nurses, physicians, and other ward staff that are used in clinical decisions. Glucose testing is currently the most widely performed bedside test. Because(More)
