Current review of pain最新文献

This article reviews the objectives of psychological evaluations, as well as the standard pain center evaluation protocol that uses a pain questionnaire, a structured clinical interview, and pain assessment measures that include pain intensity rating scales and the McGill Pain Questionnaire. The most frequently used measures of psychological status, such as the Beck Depression Inventory and the Minnesota Multiphasic Personality Inventory (MMPI), are reviewed. Psychological predictors of invasive procedures and of disability are also outlined. The importance of listening to the patient in a multidisciplinary setting is emphasized.

The topic of reflex sympathetic dystrophy (RSD) has generated an increasingly significant volume of medical literature and controversy over the last decade. A search of PubMed, the online site of the National Library of Medicine, for papers on RSD reveals nearly 2200 articles on the topic (using algodystrophy as the search word, wherein RSD references are also included, and more older and European articles are also listed). From 1991 through 1998 inclusive there is an average of nearly 100 articles per year on the topic, which represents more than a third of all the articles referenced since 1965. In the decade of the 1980s, there is an average of 64 articles per year, 74 per year in the last half of the decade and 54 per year in the first half. Prior to the decade of the 1980s, one finds an average of 40 articles per year back to the mid-1960s. The controversy surrounding the disorder centers around the nature of the problem and whether it is a primary organic disorder or a primary psychogenic disorder associated with the accomplishment of some secondary gain. If it is the former, then clearly research should continue to determine the nature and etiology of the malfunctioning organ(s). If, on the other hand, RSD is a psychogenic disorder, then the medical community does well to focus mainly on the peripheral manifestations of the problem. In that instance, therapy should be primarily psychological and cognitive with regard to the secondary gain, and persistent organic treatments are unlikely to improve the condition in general and worsen individual cases.

Hospice care has irrevocably changed the landscape of healthcare. First seen as an alternative to dying in the impersonal, highly technical environment of the hospital, it provides comprehensive palliative, supportive care in patient-oriented settings, usually at home or, in some instances, special hospice units. Now the challenges of hospice care largely go beyond the philosophic to include the organizational, demographic, and pragmatic difficulties of providing such care in various settings. This article discusses some of those challenges, including a number of principles and techniques gleaned particularly from the hospice experience for successful pain management in the home setting.

Patients of different ages present with different lumbar spine afflictions. These afflications are linked to age-related changes in the intervertebral disc, zygapophyseal joints, and capsuloligamentous structures. Disc degeneration precedes all other changes, resulting in nonspecific low back pain that can potentially advance into specific low back pain conditions.

Neuropathic pain is difficult to diagnose and treat. Both can be made easier if the nerve dysfunction can be quantified. The two basic modes of evaluation are subjective and objective. This article presents currently used methods in both arenas. Discussion is also given to some basic neurophysiology necessary to understanding the use of these testing methods.

Temporomandibular disorders (TMDs) are currently viewed as a family of related pain conditions in the craniofacial muscles, temporomandibular joint, and associated structures. The etiology and pathophysiology of pain is still far from being known, but several important neurobiological aspects have emerged in the last decade. This article reviews the present knowledge on three clinically relevant topics in TMD: referred pain mechanisms, somatosensory changes, and sensory-motor integration in the craniofacial region. It is proposed that the synthesis of this information from systematic studies in experimental animals and healthy human volunteers together with controlled clinical trials in well-defined patient populations is an essential prerequisite in order to advance the diagnostic procedure and management of TMD pain.

Over the years, a number of treatments for persistent low back pain following spine surgery, the failed back surgery syndrome (FBSS), have been developed. The complexity of the clinical problem, the multidimensional nature of chronic pain, and general lack of rigorous study design, however, have obscured outcome assessment and hampered efforts to optimize patient selection criteria. Recent work has focused on refinement of existing therapies for FBSS and identification of factors that influence outcome and improve patient selection criteria. In combination with more rigorous study methodology, these efforts have led to improved understanding of the clinical response to a number of pharmacologic, surgical, and neuromodulation therapies for FBSS.
