The relatively recent focus on pain as a subjective experience has led to dramatic improvements in our understanding of the complex psychological processes that represent and control pain buy 100 mg eriacta otc erectile dysfunction doctor. There has also been an en- hanced understanding of the ontogenetic generic eriacta 100mg impotence trials, socialization, and contextual de- terminants of pain. Mechanisms responsible for the complex synthesis of sensations, feelings, and thoughts underlying pain behavior have been the target of concerted research and clinical investigation. This volume expli- cates our current understanding of the current theory, research, and prac- tice on these complex psychological processes. We are proud of our list of contributors that includes some of the most influential and productive pain researchers in the world. Although the book is primarily intended for psychologists (practitioners, researchers, and students) managing, investigating, and studying pain, it would also be of interest to a variety of other professionals working in this area (e. The book is also suitable as a textbook for graduate and advanced undergraduate courses on the psychology of pain. We owe a debt of gratitude to the many sources of support made avail- able to us. In the first instance, we are most appreciative of the commit- ment, inspiration, and hard work of the people who work with us in the xi xii PREFACE common cause of developing a better understanding of pain and pain con- trol. Our graduate students and project staff continuously offer fresh per- spectives, ideas, and boundless energy, giving us a great hope for the future and confidence in our work today. We also acknowledge many outstanding colleagues who generously exchange ideas with us about important issues relating to the psychology of pain. These ideas are a source of inspiration and make us proud of the many scientific and clinical advances our field has achieved. Work on this project was supported, in part, by a Canadian Institutes of Health Research Investigator Award to Thomas Hadjistavropoulos and by a Canadian Institutes of Health Research Senior Investigator Award to Ken- neth D. Related work in our laboratories has been supported by the Canadian Institutes of Health Research, the Social Sciences and Humanities Research Council of Canada, and the Health Services Utilization and Re- search Commission.

Craig An Introduction to Pain: Psychological Perspectives Thomas Hadjistavropoulos University of Regina Kenneth D. Craig University of British Columbia Pain is primarily a psychological experience. It is the most pervasive and universal form of human distress and it often contributes to dramatic re- ductions in the quality of life. As demonstrated repeatedly in the chapters to follow, it is virtually inevitable and a relatively frequent source of dis- tress from birth to old age. Episodes of pain can vary in magnitude from events that are mundane, but commonplace, to crises that are excruciating, sometimes intractable, and not so common, but still not rare. The costs of pain in human suffering and economic resources are extraordinary. It is the most common reason for seeking medical care, and it has been estimated that approximately 80% of physician office visits involve a pain component (Henry, 1999–2000). The distinction between pain and nociception provides the basis for fo- cusing on pain as a psychological phenomenon. Nociception refers to the neurophysiologic processing of events that stimulate nociceptors and are capable of being experienced as pain (Turk & Melzack, 2000). Instigation of the nociceptive system and brain processing constitute the biological sub- strates of the experience. But pain must be appreciated as a psychological phenomenon, rather than a purely physiological phenomenon. Specifically, it represents a perceptual process associated with conscious awareness, selective abstraction, ascribed meaning, appraisal, and learning (Melzack & Casey, 1968). Emotional and motivational states are central to understand- ing its nature (Price, 2000). Pain requires central integration and modula- tion of a number of afferent and central processes (i.

Typified by sunburn buy 100 mg eriacta with visa erectile dysfunction support groups, first-degree burns are inconsequential in subsequent burn manage- ment cheap 100 mg eriacta overnight delivery erectile dysfunction shakes menu. Oral intolerance and severe discomfort requiring hospitalization may accompany large first-degree burns. These burns have a red, hyperemic appearance of the surface, which, along with the hypersensibility and discomfort, is typical of these injuries (see Fig. Second-degree burns, also called partial-thickness burns, involve variable amounts of dermis (see Fig. Second-degree burns are subdivided into superfi- cial and deep second-degree wounds. In superficial second-degree burns, the epidermis and the superficial (papillary) dermis have been damaged. A moist, pink appearance that blanches with pressure, along with extreme pain and hyperesthesia, is common in these injuries. Regeneration occurs by proliferation of epithelial cells from hair follicles and sweat gland ducts. Heal- ing is almost complete within 3 weeks, leaving no scarring if no complications occur. In deep second-degree burns, however, the epidermis, papillary dermis, and various depths of the reticular (deep) dermis have been damaged. Complete healing take more than 3 weeks and scarring and infection are common. These injuries are best treated surgically, since excision of the dead tissue and skin grafting shorten hospital stay and improve outcomes. Deep second-degree burns tend to be hypoes- thetic, presenting with less pain than superficial burns. They have a white–pink appearance and blistering does not normally occur, or is present many hours after the injury. A B FIGURE6 The laser Doppler scanner (A) is helpful for the diagnosis of burn wound depth. Its sensitivity and specificity are best between 48 and 72 h after the injury. It is placed over the area to be scanned (B), and in few seconds it produces a digitized image of the burn wound. Typical ap- pearance is that of a hyperemic area with severe discomfort and hyperestesia. Such burns do not blister, and they generally desquamate between 4 and 7 days after injury. Initial Management and Resuscitation 19 A B FIGURE 8 Second-degree burn injuries (or partial-thickness burns) present with different degrees of damage to the dermis. They usually blach with pressure and do not usually leave any permanent scarring. Deep portions of the dermis have been damaged and they tend to leave permanent changes on the skin (C, D). Initial Management and Resuscitation 21 In contrast to the former injuries, third degree burns or full-thickness burns never heal spontaneously, and treatment involves excision of all injured tissue (Fig. In these injuries, epidermis, dermis, and different depths of subcutaneous and deep tissues have been damaged. Pain involved is very low (usually with marginal partial-thickness burns) or absent. In infants and patients with immersion scalds, the burns may appear cherry red, and they may be misleading in nonexperienced hands. Burns that affect deep structures, such as bones and internal organs, are categorized as fourth-degree burns. These injuries are typical of high-voltage electrical injuries and flammable agents, and have a high mortality rate.

There is disappointingly little research to guide the practitioner on size and constitution of CBT groups cheap 100 mg eriacta erectile dysfunction after prostate surgery, or on process (Keefe 100mg eriacta for sale impotence drugs for men, Jacobs, & Under- wood-Gordon, 1997). Group versus individual treatment is not a major re- search issue, given the efficacy of CB group programs and the increased costs of treating patients individually. There is a move toward patient-led and self-management groups, of which the work of Lorig and colleagues (Lorig, Lubeck, Kraines, Seleznick, & Holman, 1985) is an important early ex- ample. They trained lay leaders, who then led large groups of arthritic pa- tients (and family or friends where they wished to attend) in largely experi- ential learning for six weekly 2-hour groups. Gains in pain and activity frequency were comparable to those from similar CBT programs; changes in depression, low at the outset, were modest, and there were none in self- rated disability. Although this is now a widely replicated model, and there are doubtless deficits in knowledge and strategies to be remedied among 284 HADJISTAVROPOULOS AND WILLIAMS chronic pain patients, the model cannot be extrapolated unquestioningly to populations of patients who are frequent users of health care and are signif- icantly distressed and disabled. Attending support groups over a 1-year period shows no enhanced treatment gains in terms of sick leave, function, and pain (Linton, Hellsing, & Larsson, 1997). Together the just cited studies suggest support groups may have a place as an adjunct approach among chronic pain patients, but provide evidence against reduc- ing the level of expertise and time and resources put into CBT group pain management programs. Commentary In 1992, Keefe and colleagues expressed widely held hopes that research us- ing larger sample sizes would demonstrate the “active ingredients” of CBT treatment packages; discover how to improve maintenance of treatment gains; and extend CBT to other patient groups, such as those with osteo- arthritis, rheumatoid arthritis, and sickle-cell disease. Meanwhile, extensive CBT programs have been subject to cost cutting, thereby reducing the quality and quantity of established treatment facilities. Research has been limited largely to small volunteer studies, making it particularly hard to model change in treatment (and maintenance after treatment) or to carry out stud- ies with sufficient sample size to do justice to the many interacting vari- ables affecting outcome. The questions identified by many clinicians and researchers (Turk, 1990), and to which some anticipate answers from large treatment studies or meta-analyses, are, “Which are the right and wrong patients? Meanwhile, no consistent findings have emerged from many component dismantling trials (see Morley et al. This is not so remarkable given that all investiga- tions are subject to local peculiarities of referral, funding, and acceptance and rejection criteria. We can, however, draw some practical suggestions from mainstream psychology: People with major depressive disorder are unlikely to engage or participate until they have more hope and sense of a tolerable future, so immediate treatment of depression is indicated; pho- 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 285 bias of groups or health care settings may preclude common methods and settings for delivery. As for “essential ingredients,” the implicit model of component disman- tling studies of additive, independent, and specific component-outcome re- lationships is too far from reality to provide an adequate model for analy- sis. One can no more ask which are the essential ingredients of a cake— butter, sugar, flour, or eggs. The absence of any, or serious compromises of quality, will result in a different and inedible end product; minor variations in one or another or the addition of cocoa or currants does not render it in- edible. The interaction of components (the mixing and cooking process) is crucial, yet team processes and program integration are rarely described. At a risk of stretching the analogy too far, the skills of the cook are also rele- vant, and cost-cutting pressures on programs are likely to reduce efficacy. As NASA engineers profess: “Faster (briefer), better, cheaper: you can have any two of these, but not all three. What is curious is the extent to which discontinuities were evident (beyond those included in the system- atic review) in studies’ rationales, treatment methods, and outcomes cho- sen. Almost all study introductions invoke costs and demands on health care and loss of work; few measure either. At least half do not make clear whether they expect pain ratings to change, although these are universally measured and reported. Perhaps because of editorial restrictions, the fac- tors affecting the choice of components, their order, timing, and processes, are rarely described. Whether these apparent confusions in accounts of treatment reflect real contradictions embedded in treatment methods and processes is an open question. It is of some concern that beyond its basic assumptions—that thoughts, emotions and behavior influence one another, that behavior is determined both by the interaction of individual and his or her environment, and that individu- als can change their thoughts, emotion, and behavior (Keefe et al. On education, argu- ably, psychologists and their colleagues unnecessarily restrict themselves to the initial gate control model (Melzack & Wall, 1965), underusing the rich neurophysiological research which has resulted from the initial proposal of that model. There is a dearth of models described in terms that are accessi- ble to the lay public of central nervous system plasticity developing subse- quent to pain, and of the nonconscious psychological processes that influ- ence the processing of pain at spinal and supraspinal levels. Emotion is still poorly integrated with this, perhaps because of the lack of adequate overall 286 HADJISTAVROPOULOS AND WILLIAMS models and the shortage of data on nonconscious processes (Keefe et al.
