    Notes: Summary A prospective, two-phase, drug utilization review (DUR) was performed at the Royal Adelaide Hospital (RAH) to determine the extent and pattern of vancomycin use. For all patients commencing oral or parenteral vancomycin, treatment indication, route of administration, duration of therapy, results of culture and sensitivity tests, adverse drug reactions and results of therapeutic drug level monitoring were recorded. Vancomycin courses were classified as being for therapy or prophylaxis and compared with predetermined audit criteria to assess appropriateness of use. During the 8 week initial phase, data on 62 treatment courses in 59 patients were recorded, 50% for therapy and 50% for prophylaxis. Sixty four percent were classified as inappropriate, occurring in 32% of therapeutic courses and 97% of those for prophylaxis. During the 10 week re-evaluation, conducted 10 months later, data for 43 treatment courses in 43 patients were reviewed, 42% for therapy and 58% for prophylaxis. Sixty five percent were inappropriate occuring in 17% of therapeutic courses and 100% of the prophylactic courses. When compared with the initial phase, the re-evaluation demonstrated a decrease in the empirical use of vancomycin in the combination treatment of neutropaenic fever and also in the duration of vancomycin use for surgical prophylaxis. During both study phases, criteria contraventions were mostly due to inappropriate indication or duration of therapy. The cost of inappropriate vancomycin use was reduced by over 50% between survey phases, from $Aus11,500 or 55% of total vancomycin cost during the initial phase to $Aus3,600 or 25.7% during the re-evaluation. The most effective of the remedial strategies implemented after the initial phase was direct consultation with prescriber groups. The effectiveness of this DUR has provided the basis for an ongoing DUR programme at the RAH which has been met with general acceptance by hospital clinicians and administrators.

    Notes: Abstract We consider the grand canonical partition function for the ordered one-dimensional, two-component plasma at fugacityζ in an applied electric fieldE with Dirichlet boundary conditions. The system has a phase transition from a low-coupling phase with equally spaced particles to a high-coupling phase with particles clustered into dipolar pairs. An exact expression for the partition function is developed. In zero applied field the zeros in theζ plane occupy the imaginary axis from −i∞ to −iζc and iζc to i∞ for some ζc. They also occupy the diamond shape of four straight lines from ±iζc to ζc and from ±iζc to −ζc. The fugacityζ acts like a temperature or coupling variable. The symmetry-breaking field is the applied electric fieldE. A finite-size scaling representation for the partition in scaled coupling and scaled electric field is developed. It has standard mean field form. When the scaled coupling is real, the zeros in the scaled field lie on the imaginary axis and pinch the real scaled field axis as the scaled coupling increases. The scaled partition function considered as a function of two complex variables, scaled coupling and scaled field, has zeros on a two-dimensional surface in a domain of four real variables. A numerical discussion of some of the properties of this surface is presented.

    Notes: Abstract We consider the statistical mechanics of a fluctuating string (1D solid-on-solid model) ofN columns with a contact energy term displaying a critical wetting transition. For this model we derive a contour integral representation for the finite-size partition function. From this representation we derive a polynomial representation and obtain the Lee-Yang zeros forN ≲, 100. Through the asymptotic evaluation of the contour integral we evaluate the zeros for higherN. This asymptotic evaluation displays a Stokes phenomenon providing a different viewpoint of the mechanism by which a phase transition can arise, supplementing the picture of Lee and Yang. We also reproduce and extend somewhat the results of Smith for the finite-size scaling limit of the partition function.
