Owing to their frequency and possible consequences and considering the fact they frequently affect young people, trauma tic lesions of the thoraco lumbar spine represent a special point of interest within the field of Neurotraumatology. Traffic accidents are the commonest cause, which accounts for the high peak of occurrence between 15 and 24 years of age. It is also worth noting that according to published series nearly 50% ofthe cases affect the thoraco-lumbar junction. From an anatomical point of view, we must note the severity of thoracic spinal cord lesions especially of the thoraco-lumbar junction and of the lumbar region and be able to associate injuries ofthe conus medullaris and of the ca uda equina where there is a possibility of neurological recovery. Clinical evaluation is not always easy, but remains the basis for diagnosis and prognosis. The neurological classification proposed by FRANKEL et al. in 1969 and used at STOKE MANDEVILLE Hospital seems to retain its value. A more sophisticated study of medullary evoked potentials, as described by TsUBOKAWA can allow a more precise localisation and appreciation of the extent ofthe lesion as well as a better evaluation ofthe prognosis and ofthe evaluation of treatment in the acute phase. The neuro-radiological study should include standard views ofthe whole of the spine with antero-posterior and lateral tomograms of the fractured or luxated area. At present, the unquestionable contribution of the CT.

Future Directions In Polymer Colloids Hohamed S. EI-Aasser, and Robert H. Fitch (editors) It is appropriate that the first NATO-Advanced Research Workshop on "FUTURE DIRECTIONS IN POLYMER COLLOIDS" was held approximately fifty years after the first synthetic polymer latexes were made on a commercial scale during the mid-1930s. Since that time the field of what is now known as polymer colloids has been evolving rapidly, not only on the practical level, but also on the scientific and engineering levels. Billions of pounds of copolymers are manufactured annually by means of the emulsion polymerization process. "Commodity" polymers as well "specialty" polymers are prepared today for use in a wide variety of applications: synthetic rubber, floor coatings, paints, adhesives, binders for non-woven fabrics, high-impact polymers latex foam, additives for construction materials such as cement and concrete, and rheological modifiers. They are also used in numerous biomedical applications: such as diagnostic tests, immunoassays, biological cell-labeling, (identi fication and separation), and drug delivery systems. Small quantities of monodisperse polymer colloids are used as size calibration standards and find extensive use as model colloids to test theories in colloids surface and rheological studies. Advances have been made in our understanding of the mechanism and kinetics of the emulsion polymerization process as well as the stability of polymer colloids. Equal advances were made in engineering areas related to polymer colloids, e. g. modeling of batch, semi-continuous and continuous emulsion polymerization and copolymer ization processes."

It is particularly appropriate that this symposium on the emulsion polymeriza tion of vinyl acetate was held in recognition of the industrial importance of poly(vinyl acetate) and vinyl acetate copolymers, and their rather unique properties among emulsion polymers in general. Poly( vinyl acetate) latexes were the first synthetic polymer latexes to be made on a commercial scale: their production using polyvinyl alcohol as emulsifier began in Germany during the mid-1930s and has continued to the present day, growing steadily with the years. Indeed, poly(vinyl acetate) latexes prepared with polyvinyl alcohol are still one of the mainstays of the adhesives industry. With the passing of time, however, vinyl acetate copolymers have been developed: copolymers with maleate esters such as dibutyl maleate, acrylate esters such as ethyl acrylate and butyl acrylate, versatic acid esters, and, more recently, ethylene. These versatile copolymers have found increasing use in more sophisticated adhesives with specialized properties, adhesives for clay coatings on paper, carpet backing, and interior and exterior paints. Thus more than 45 years after the first commercial production of vinyl acetate latexes, their use is still growing, both in actual quantities and different applications. The industrial importance of vinyl acetate latexes makes the mechanism and kinetics of their emulsion polymerization of practical as well as scientific interest."
