ABSTRACT
Prolonged room temperature stability (i.e. zero particle growth) can be achieved for concentrated emulsions of perflubron (perfluorooctyl bromide) or perfluorodecalin via addition of a secondary high molecular weight, lipophilic fluorocarbon component. Due to their enhanced lipophilic character, the secondary fluorocarbon components have acceptable half-lives in the organs of the reticuloendothelial system.

Exact differentiation into stump and phantom pain is required when pain is reported after amputation. In a majority of cases appropriate treatment can improve the pain. Thermography is simple and gives a good indication of the circulation in the stump without operative intervention. It provides a key to the nature of the pain in stump and phantom. Although typical patterns occur for pain in the stump or phantom, in this study the thermographic image could confirm the presence of phantom pain, but it could not rule out errors or false statements.

An image intensifier--70mm camera--fluoroscopy system combined with a conventional X-ray tube is used for routine examination of the infant's hip. The high quality of 85% of these 70mm exposures makes immediate diagnostic interpretation possible. An even higher percentage can be achieved by most exact positioning of the patients. Apart from the radiation protection of the gonades, the X-ray skin dose of the primary beam is reduced by 90-95% compared with full size radiography using film screen combinations. This exposure technique can certainly be used not only for the examination of the infant's hip.
