Complete reviews of all the drugs discussed in this book are available through a variety of desk references and product information forms provided by the manufacturers. The clinician is referred to these references for a review of the general pharma- cology and specific contraindications of any drug dis- 18 cussed. A drug should never be used for which the clinician is not fully aware of the indica- tions, contraindications and potential side effects. In this chapter, commonly used drugs and their asso- ciated doses are provided in table form for easy refer- ence. The information concerning the use of the drugs listed in the table should be reviewed before administering any therapeutic agent. If a drug is not discussed, either insufficient data is available to war- rant its use in birds, or it has been used but has little Branson W. Harrison The doses and material presented for each drug have been compiled from numerous reference sources, in- cluding the various chapters in this book. Some of the recommended doses are based on pharmacokinetic information, and some are based totally on observa- tion. An asterisk in the formulary table indicates that the suggested dose is based on pharmacologic data obtained in some species of birds other than poultry. Notes on any adverse drug reactions should be for- warded to the Journal of the Association of Avian Veterinarians to keep colleagues informed of any problems that occur with commonly used therapeutic agents.

If the shifts in assay response were simple then they might be described by a further additive error model generic 60mg raloxifene women's health issues in malaysia. In practice the appearance of significant non-specific binding or the degradation of the label can give rise to quite complex non-linear changes in response raloxifene 60mg line women's health center clinton. Standards must there fore be used to cover the working range and give a sufficiently accurate calibration order raloxifene 60mg without prescription women's health uc. Variation in response is then described by changes in the parameters of the model used during calibration trusted raloxifene 60 mg womens health for life. The combination of a relatively large intra-batch error and an excessively flexible calibration model (i. Variation in the calibration and error model parameters may be used to estimate the inter-batch component of total error once the intra-batch sampling error has been removed. As the inter-batch component is usually relatively small interest is directed towards the overall assay error. At the same time there is greater interest in detection of small but consistent changes or “drifting” between batches before the assay must be considered “out of control” and discarded. Cusums are a useful diagnostic aid though some users find them difficult to interpret. Inter-sample and clinical sources of variance So far the assay instrument has been assessed only by its laboratory performance. The physician will then expect the laboratory to monitor and maintain the expected assay performance. In some laboratories a limited patient record is available and could be combined with a model of patient response to give further information for both physician and laboratory. This, however, is a subject for further research and lies beyond the current confines of immunoassay data-processing. Linear or point-to-point interpolation requires a large number of standards at a high replication to achieve sufficient precision because there is no smoothing of individual standard errors. Spline functions are usually so flexible that interpolation errors can occur despite an excellent fit to the calibrations. Neither method can readily introduce the kind of prior experience that the assayist brings to manual calibration. The use of a model is based upon the expectation that the underlying form or shape of the assay response will remain consistent though it may be masked by errors. The more constrained and the less flexible the model becomes the greater is the prior knowledge of assay behaviour, and so a smaller number of standards will be required for the same expected calibration error. In practice it is rare for the assayist to choose and validate a model which most simply describes the response, preferring to use a readily available form which does not show particular significant residual errors after fitting. Indeed, the occasional “poor” fit may be taken to indicate a need for a more flexible (higher order) model. This can lead to the order of the model (the number of parameters) approaching or even equalling the number of calibra tions. Under these conditions the use of a model may be worse than simple linear interpolation. The two basic models commonly employed in immunoassay calibration are (i) the empirically based logit, and (ii) the mass-action form, derived from assump tions about the underlying unit processes. The basic two-parameter logit model is drawn from observation of the near sigmoid form of many immunoassay dose- reponse curves when expressed in a “bound label” versus “log dose” co-ordinate frame. Subsequent recognition of consistent errors when the simple logit is used with some assay systems or with inaccurate normalization have led to the addition of further parameters to achieve the desired “flexibility”. In practice, the four- parameter form is usually selected as a general model of assay response. A more fundamental approach is to derive the assay response directly from the underlying mass-action laws. This has the attraction that terms can be added as they are thought significant to produce a model characteristic of the assay used. Additional binding sites may be specified when they are found to be the dominant influence upon assay response. Ideally then, the assayist should endow the program with the experience he would bring to manual curve-fitting by selecting the simplest form which will adequately describe the assay response. As an assayist gains familiarity with an assay procedure a steady improvement can often be observed as a smoothing of the calibration curve. When an unreliable assay consistently shows changes of form then a more flexible model must be chosen and the number of calibrators increased in step with the parameters. A suitable form can be selected by running a number of typical batches with different models to confirm the absence of trends in the residual errors and the stability of inter polation. The mass-action and logit models discussed here have been fully described in numerous publications including those of Rodbard et al. Curve-fitting algorithms Selection of even a low-order non-linear model can give rise to curve-fitting difficulties which are exacerbated by data which include outliers and by the constraints of current microcomputers. The mass-action models all share the dis advantage that they require the evaluation of an implicit function. Finding the roots of even a quadratic function can occasionally lead to ill-conditioning. These problems mean that robust algorithms must be used when fitting the mass-action models. The hardware limitations are likely to be relaxed considerably in the next few years but assay data which include occasional outliers are likely to remain. The requirement for robust and reasonably fast optimization with limited computational power tends to favour the use of specialized algorithms designed around a particular model. The absolute error is less sensitive to the effects of non-Gaussian outliers and has been proposed for a number of problems (Kiountouzis [8]). It is important that the user is able to examine the curve fit graphically to detect problems not indicated by the residual errors. The ability to plot on the screen and on to hard-copy in reasonably high resolution is an important advantage of the microcomputer. Drawing the calibration curve by hand is sometimes avoided and character-based hard-copy is frequently too coarse for easy interpretation. Plotting the calibration curve together with the data and expected errors gives a very clear summary of the goodness-of-fit. Apart from the basic goodness-of-fit, summarized by an “F ” ratio for example, it is important to allow a check for the possibility of consistent trends in the residuals which would suggest that other models should be considered. These trends are difficult to discern from the calibration curve or a table of residual errors. A plot of the residual errors in both response and dose for each calibration allows useful evaluation without further detailed analysis by presenting explicitly to the user the relative magnitudes of the fitting errors and the expected random measurement errors.

In anaesthesiology, the debate continues about whether a Sell- ick manoeuvre (backward pressure on the cricoid cartilage) is a necessary component of a rapid-sequence intubation. The question for an author assigned the task of writing the airway chapter in a new edition of a standard textbook is different from that of an investi- gator interested in revisiting the question of whether or not the technique is bene¿cial. For one, it is a matter of adjudicating the technique’s inclusion; for the other, it is a question of hypothesis and result. For the student, the standard text becomes the gold standard; for the experienced practitioner, the hypothesis-driven study may become the foundation of a new reality. The tension is clear and the discriminatory responsibility of author–reader relationship is highlighted. Another dif¿culty for the author is the necessity of catering to multiple reader types in a single manuscript or chapter. It is apparent that readers vary in their attention span and the manner in which they obtain and process information. For some, the text itself is the key; for others, the graphics, ¿gures and tables are the most important area and primary focus. Although most authors perceive their articles to be a consistent whole, the most discerning provide each reader a content and style with a unique experience, ensuring that graphs, ¿g- ures, tables and text tell the story independently yet collaboratively. Figures and tables are felt to be the most effective way to present results, but much of the standard textbook relies on a complete, easily understood explanation of technique or process. All graphic material should be presented in a manner that is easy to interpret, and the captions or titles should be understandable independently of the accompanying text. It is dangerous to suppose that the reader will follow the author’s detailed logic to gain an independent interpretation of the data; rather, the author must sell the message in all locations. This is a dif¿cult task and one that becomes increasingly complex as the subject matter broadens and the available information is more expert opinion than objective data. In this setting, the experienced context expert is able to present a balanced assessment of available information in a man- ner that is both useful and intellectually and practically challenging. There are general rules that authors must consider: The manuscript must establish the subject and context clearly. The reader should not be confused about the article’s purpose or become confused by a poorly constructed argu- ment. The peer reviewers and editor have a responsibility to the author and reader to help re¿ne the manuscript and to make it relevant while avoiding hyperbole. The author must understand that reviewers are likely authors themselves and that personal opinion and experience, linguistic and stylistic preferences and writing mannerisms are prevalent. The responsibility for appropriate and ethical publication rests with the author and editor; the responsibility for disseminating the information rests with the publisher; the responsibility for appropriate utilisation of the information rests with the reader. The partnership is becoming increasingly important, and the reader must take increasing responsibility for discriminatory consump- tion. Electronic systems and open publishing platforms reduce the ability of peer and edi- torial review to re¿ne the ¿nal submission, and the reader must undertake many of these responsibilities personally. The learning–reading cycle comes full circle: from uncritical acceptance of the information presented to scepticism. Ultimately, the reader is responsible for performing not only a critical review of information presented but also for placing the relevant pieces into an appropriate context.
