This article analyzes literature on pain management programs in hand therapy. Philosophical and practical issues that may influence the approach to pain are reviewed. Possible explanations for the relative lack of interdisciplinary/comprehensive approaches to pain are put forth. Conditions under which more comprehensive treatment should be considered are discussed.
Gap junctions consist of closely packed pairs of transmembrane channels, the connexons, through which materials of low relative molecular mass diffuse from the cell to neighbouring cells. In liver, connexons consist of six protein subunits which, until now, were believed to be identical. However, besides the major polypeptide of relative molecular mass (Mr) 28,000 (and see refs 4 and 6), a component of Mr 21,000 (21K) has been repeatedly observed in liver. The amino-terminal sequence (18 residues) of this less abundant protein shows that it is related to, but distinct from, the Mr 28K protein. Immuno-staining and immuno-precipitation show both proteins to be in the same gap junctional plaques. Thus, it seems that hepatic gap junction channels (and by extension possibly others) are composed of two (or more) homologous proteins.
A system is described for the stabilization and evacuation of the critically ill in South Australia, with a discussion of experience in 278 patients. The integration of activities of peripheral medical practitioners, major teaching hospitals, and the ambulance transport authority (St John Ambulance Council) is paramount. Modes of communication are by "urgent line" telephone and radio. Advanced life-support equipment is portable, may be placed in any ambulance vehicle, and is used and maintained principally by the staff of intensive care units. The design characteristics of a suitable road vehicle and fixed-wing aircraft are considered, with emphasis on dimensions for the particular needs of advanced life-support. The cost of transporting such a patient is approximately two-thirds of an average bed day cost in a public hospital, plus the basic ambulance charge. The number of patients who need such measures is 0.2% of the total number of patients carried by ambulance per annum.
