The objective of this study was to evaluate and compare various methodologies of measuring the characteristics of pressure ulcers. This prospective, four-week, follow-up study consisted of 20 patients, of whom 17 completed the study. Each patient had at least one full-thickness pressure ulcer (surface area between 1.2 and 61.6 cm2) that had been present for(More)
y composition was studied in 31 patients receiving chemotherapy for small-cell lung cancer. Patients were randomly assigned to receive either 4 weeks of total parenteral nutrition (study group) or to continue a self-regulated oral diet (control group). The relationship between height and total body nitrogen was altered initially for patients who had lost(More)
In vivo neutron activation analysis has been used to measure bone mineral content in the central skeleton where osteoporotic fractures occur. To be of diagnostic value, the results must be normalized for body size. From data obtained from 74 healthy children and adults up to 55 years of age, we have found that the calcium in the central skeleton is(More)
Data on five mining populations exposed to Rn progeny have been used to estimate the lifetime risk of lung cancer resulting from occupational and environmental exposure under current standards. Slopes of dose-response relations for lung cancer show a tendency to decrease with increasing dose. Our best estimate of curvilinearity is given by raising dose to(More)
A mehtod of measuring body nitrogen by neutron capture gamma analysis is described. The neutron flux is provided by four collimated 5 Ci Pu-Be sources, placed to give a bilateral irradiation of the subject. The 10-83 MeV thermal neutron capture gamma rays from 14N are detected by two heavily shielded 5 in X 4 in NaI(Tl) detectors. Results indicate a(More)
In 1998 we surveyed our radiologists on teleradiology satisfaction. Results were generally positive. In 2002 we experienced a sevenfold case increase in teleradiology volume. The present study surveyed the radiologists again. The hypothesis was that, with increased case volume and radiologist experience with the system, ratings would increase. Image quality(More)
