V Preface The present second edition of the Color Atlas of Pharmacology goes to print six years after the first edition. Numerous revisions were needed, highlighting the dramatic continuing progress in the drug sciences. In particular, it appeared necessary to in- clude novel therapeutic principles, such as the inhibitors of platelet aggregation from the group of integrin GPIIB/IIIA antagonists, the inhibitors of viral protease, or the non-nucleoside inhibitors of reverse transcriptase. In each instance, the primary emphasis was placed on essential sites of action and basic pharmacological princi- ples. Details and individual drug properties were deliberately omitted in the interest of making drug action more transparent and affording an overview of the pharmaco- logical basis of drug therapy. The authors wish to reiterate that the Color Atlas of Pharmacology cannot replace a textbook of pharmacology, nor does it aim to do so. Rather, this little book is desi- gned to arouse the curiosity of the pharmacological novice; to help students of me- dicine and pharmacy gain an overview of the discipline and to review certain bits of information in a concise format; and, finally, to enable the experienced therapist to recall certain factual data, with perhaps some occasional amusement. Our cordial thanks go to the many readers of the multilingual editions of the Color Atlas for their suggestions.

Pathological measures are often primary methods (separate from the symptoms associated with the primary disease) for understanding whether a treatment is © 2005 by CRC Press LLC working purchase 120mg sildalis problems with erectile dysfunction drugs. For example sildalis 120mg generic erectile dysfunction treatment seattle, measurement of the size of a brain tumor on MRI scans can form a primary data source with which to compare various chemotherapy treatment regimens. In spine studies, radiographic fusion is often used as a surrogate marker for success of a fusion procedure, even though this marker does not appear to correlate with patient outcomes in most other respects. Clearly, the use of pathological measures may be an important basis to decide on treatment efficacy at a basic level, but these measures likely require supplementation with other types of outcomes to decide whether a treatment on the whole is worthwhile at patient level. Active pathology may result in some type of impairment, but not all impairments are associated with active pathology (e. Impairments can usually be objec- tively specified by an observer such as a physician or surgeon, and are classified in a standard text, the American Medical Association Guide to Impairment. For example, a limitation in shoulder range of motion secondary to a cerebral vascular accident may greatly affect the life of an active patient and be of little importance to a sedentary elderly patient. We will focus our discussion on the disablement model developed by Saad Nagi, a sociolo- gist,12 the International Classification of Impairments, Disabilities and Handicaps (ICIDH-1),13 and its current revision, the International Classification of Functioning, Disability and Health (ICF). It may not constitute a disability for some occupations (manual laborer) but would produce complete disability for others (concert pianist, surgeon). This is a fundamental distinction of critical importance to scholarly discussion and research related to disability phenomena. We will not review the ICIDH-1 classification except to note that in principle this original system was designed as a model for coding and manipulating data on the consequences of health conditions. Part 1 covers functioning and disability including body functions, structures, activities, and participation. Each component consists of various domains and, within each domain, categories that are the units of classification. This view fails to recognize that disablement is more often a dynamic process that can fluctuate in breadth and severity across the life course; it is anything but static or unidirectional. More recent disablement formulations and elaborations of earlier models have explicitly acknowledged that the disablement process is far more dynamic. In these newer concepts, a given disablement process may lead to further downward spiraling consequences. Pope and Tarlov15 use secondary conditions to describe any type of secondary consequence of a primary disabling condition. Commonly reported sec- ondary conditions include pressure sores, contractures, depression, and urinary tract infections, but it should be understood that they can be pathologies, impairments, functional limitations, or additional disabilities. Longitudinal analytic techniques now exist to incorporate secondary conditions into research models and are beginning to be used in disablement epidemiologic investigations. Because patient satisfaction is a multidimensional concept, it is important to start by understanding its multiple definitions. Patient satisfaction is a complex concept that may incorporate sociode- mographic, cognitive, and affective components. Although many theories for patient satisfaction have been proposed, few have been extensively tested and validated in different health care settings. Moreover, few studies have been conducted to explain associations between patient satisfaction and patient characteristics or subsequent patient behaviors. Although theories of patient satisfaction are difficult to categorize in an organized and easily comprehensible fashion, one may group these theories into intrapatient comparisons (disconfirmation theory) and differences between individual patients and health care providers (attribution theory) or other patients (equity theory). Intrapatient comparison theories explain the satisfaction phenomenon by a match between patient expectations and perceptions of medical care. Differences between what is expected and what is perceived to occur will contribute to patient satisfaction or dissatisfaction. This theory is the dominant model of nonmedical customer sat- isfaction in which consumers compare their perceptions of a product or service against prior expectations. Equity theories are based on the premise that patient satisfaction relates to whether patients believe they have been fairly treated. Equity occurs when patients compare their balances of inputs (time and money) and outputs (medical care and its results) with those of other patients. Patient satisfaction occurs when people perceive they are treated fairly; it may increase when patients perceive their outcomes as more favorable than those of other patients with the same conditions.
