The differential diagnosis must consider the possibil- ity of a cleidocranial dysostosis ( Chapter 4. A striking clinical finding at the age of 2–3 years is a painless swelling in the area of the clavicles, combined with asym- metry of the shoulders. In order to prevent worsening of the deformity, surgical correction with a wide resection of the pseudarthrotic tissue, including the periosteum, cancellous bone graft and stable fixation, should be per- formed around the age of 5 years [8, 24]. The lack of a trauma history does not neces- sarily rule out a traumatic cause of the dislocation. Factors suggestive of a congenital form include bilateral occur- rence, excessively long radius, convex instead of concave shape of the proximal surface of the radial joint and the lack of any deformation of the ulnar shaft. Under no circumstances should an attempt be made to reduce the radial head in the congenital form. The symptoms and functional restriction are usually minimal in this form, although the excessively long radius may cause problems and can be treated by resection of the head on completion of growth. The left scapula stands 6 cm higher than the right one, is smaller and is in contact with the posterior part of the skull.

However effective 25mg imitrex, the short-term nature of the dis- tress and pain associated with brief but painful medical and dental proce- dures may simply not be viewed as justifying the time and personnel costs needed to implement many psychological interventions for acute pain (Lud- wick-Rosenthal & Neufeld order 50 mg imitrex fast delivery, 1988) order imitrex 25 mg free shipping. Moreover buy generic imitrex 50 mg online, the absence of a psychiatric di- agnosis to justify provision of a psychological intervention, which is typi- cally a requirement for purposes of insurance reimbursement, may be a practical barrier to having psychological acute pain interventions be ad- ministered by psychologically trained staff. Brief and simple techniques that can be implemented quickly either through automated procedures (e. PSYCHOLOGICAL INTERVENTIONS FOR ACUTE PAIN 263 a memory-based positive emotion induction requiring less than 5 minutes of time has been shown to diminish acute pain sensitivity and pain-related physiological arousal, and could be carried out by nursing staff with limited training (Bruehl et al. Distraction techniques also require little effort to implement, and therefore may be more widely useful. Our clinical experience indicates that unless significant skills acquisition and practice time are available prior to exposure to the acute pain situa- tion, the benefits of using more elaborate interventions (e. Ideally, there would be sufficient contact time with the patient on a separate day prior to exposure to the pain stimulus for mutual selection of an acceptable intervention, for the intervention to be taught, and for patients to practice the skills on their own prior to the pain (using taped intervention instructions if appropriate). If less time is available, it is im- portant to select interventions that are reasonable for the patient to learn and practice adequately in the time that is available. Information provision and distraction interventions are most amenable to limited practice time, followed in (approximate) ascending order of difficulty by coping self- statement interventions, breathing relaxation, imagery techniques, hypno- sis, progressive muscle relaxation, and combined approaches. Patient acceptance and adherence may be another barrier to effective use of psychological interventions. Passive distraction techniques such as listening to relaxing music are likely to be accepted easily by patients. How- ever, unless patients are provided with a compelling rationale for use of in- terventions that require active practice (e. Even when intervention skills have been learned, results of a large-scale efficacy study of relaxation for postsurgical pain indicate that reminders to practice the technique are required for ben- eficial effects to be achieved (Good et al. CONCLUSIONS Results of controlled clinical trials testing the efficacy of psychological in- terventions for acute pain associated with burn management, labor, medi- cal diagnostic procedures, venipuncture, dental procedures, and surgery suggest that these interventions are often effective for pain reduction and do not appear to be harmful. However, controlled trials have rarely tested the efficacy of individual strategies, but rather have examined various com- binations of information-provision, relaxation-related, and cognitive strate- gies. It is therefore not possible to make determinations as to the clinical superiority of one type of intervention over another based on available tri- 264 BRUEHL AND CHUNG als. Audiotaped relaxation-related interventions do appear to be effective in some situations, although “live” intervention delivery by trained staff for the initial session is likely to optimize results if time and resources permit. There is little evidence to justify the use of psychological interventions as an alternative to standard pharmacological approaches, although there is much evidence that they have significant clinical utility in conjunction with pharmacological approaches. Although there are some indications that individual difference variables may impact on efficacy of various types of psychological interventions, there are insufficient data available to use indi- vidual difference variables for selection of optimal intervention types in routine clinical decision-making. Given the limitations of the available re- search, factors such as time constraints, resources, and patient preference are likely to be the most useful in selection of interventions.

Craig An Introduction to Pain: Psychological Perspectives Thomas Hadjistavropoulos University of Regina Kenneth D purchase imitrex 25mg. Craig University of British Columbia Pain is primarily a psychological experience cheap 25 mg imitrex overnight delivery. It is the most pervasive and universal form of human distress and it often contributes to dramatic re- ductions in the quality of life discount imitrex 50mg overnight delivery. 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. This formulation acknowledges the importance of various levels of anal- ysis of pain. The biological sciences (molecular biology, genetics, neuro- physiology, pharmacological sciences, etc. Ultimately, however, a unified theory of pain must integrate this understanding with the product of work in the behavioral and social sciences, as well as the hu- manities, because pain cannot be understood solely at the level of gene ex- pression, neuronal firing, and brain circuitry. Many of the serious problems in understanding and controlling pain must be understood at the psycho- logical and social level of analysis. What accounts for some people reacting dispassionately and others with great distress to what appears to be the same degree of tis- sue damage? The discipline of psychology must play a central role in the study, as- sessment, and management of pain. It is not surprising that Ronald Melzack, one of the developers of the most influential theory in the field of pain, is a psychologist. Nor is it unexpected that at least 2 of the 10 most influential clinicians and researchers in the field of pain (as assessed by survey of a random sample of members of the International Association for the Study of Pain [IASP]) are psychologists (Asmundson, Hadjistavropoulos, & Anto- nishyn, 2001). These two individuals (Ronald Melzack and Dennis Turk) are contributors to this volume. In this book we have tried to capture major features of the psychology of pain and the most influential contributions of psychologists to pain re- search and management. We are primarily interested in the ultimate impact of advances in understanding and controlling pain. Hence, although much of the volume covers applied issues, basic processes are also given careful consideration. FROM DESCARTES TO THE NEUROMATRIX Historical trends demonstrate the importance of psychological mechanisms. Descartes’s (1644/1985) early mechanistic conceptions of pain resulted in the biomedical specificity theory that proposed that a specific pain system transmits messages from receptors to the brain. This theory is sometimes referred to as “the alarm bell” or “push button” theory (Melzack, 1973), INTRODUCTION 3 because of its apparent simplicity.
