The decisions taken in medicine every day cover a vast field, stretching from prescriptions and biohumoral and instrumental examinations to the choice of nutritional, pharmacological or surgical therapy. The decision communicated to the patient is both the end result of the individual cultural and clinical preparation of the therapist and the start of a technical and scientific programme aimed at improving the conditions (and quality of life) of the patient. Scientific application of a decisional analysis study tends to guarantee the possibility of ensuring the most suitable treatment on the basis of available resources and thereby introduces a further pharmaco-economic instrument of assessment. Moreover, if this method is programmed for rationalising the operating methods of several teams which operate on the same type of patients, decisional analysis becomes the first step in setting up ‘therapeutic protocols”, systematic and scientific distribution of professional activity over the territory. An experimental study is therefore presented regarding a recurrent urologic pathology, which starting from an analysis of life expectation, quality of life and cost of applied resources, aims at constructing an operating routine and the formation of a therapeutic protocol.

Various dialyzers and acid-base balance in haemodialysis: 12 patients aged 32 to 52 years in periodic haemodialysis (4hx3) with residue diuresis absent, were examined during four trimestrial cycles with four different dialyzers (Nephross 16 F I60, Gambro Lundia Optima I3,5 micron, RP 5I0, Vita 2). The acid-base balance was examined 30 days after starting of each cycle. The results are reported and discussed.

In questo intervento è affrontato il problema di come il rispetto per la storia e per la tradizione possa, con l'ausilio del medium grafico, divenire un parametro essenziale per la formulazione di una poetica architettonica consapevole. Tale concetto viene qui espresso attraverso il confronto tra gli scritti e le opere di un teorico-figurato come G.B. Piranesi, di un teorico-architetto come Adolf Loos e di un architetto operante come Louis Kahn.
