OBJECTIVE: To review the evidence on safe and effective prescribing of opioids for chronic non-malignant pain.

QUALITY OF EVIDENCE: MEDLINE was searched using the terms “opioid effectiveness” and “adverse effects.” There is strong evidence that opioids are effective for both nociceptive and neuropathic pain, but limited evidence that they are effective for pain disorder. There is little information on their effectiveness at high doses or on the adverse effects of high doses.

MAIN MESSAGE: Opioids should be initiated after an adequate trial of acetaminophen or nonsteroidal anti-inflammatory drugs for nociceptive pain and of tricyclic antidepressants or anticonvulsants for neuropathic pain. Patients should be asked to sign treatment agreements and to give informed consent to treatment. Patients should experience a graded analgesic response with each dose increase. Titrate doses of immediate-release opioids slowly upward until pain reduction is achieved, and then switch patients to controlled-release opioids. Most patients with chronic non-malignant pain can be managed with<300 mg/d of morphine (or equivalent).

CONCLUSION: Opioids are safe and effective for managing chronic pain.

Violence, stress, and somatic syndromes.

Crofford LJ.

Center for the Advancement of Women’s Health, University of Kentucky. lcrofford@uky.edu.

Syndromes characterized by pain, fatigue, mood disorder, cognitive dysfunction, and sleep disturbance have been referred to as stress-related somatic disorders by virtue of the observation that onset and exacerbation of symptoms occur with stress. These syndromes include but are not limited to fibromyalgia, chronic fatigue syndrome, temporomandibular disorder, and irritable bowel syndrome. As with most chronic illnesses, genetic susceptibility and lifetime environmental exposures play a role in creating vulnerability to disease. Cumulative lifetime stress has been associated with a number of physiologic changes in the brain and body that reflect dysregulated hormonal and autonomic activity. Exposure to the stressor of violence is likely to create a state of vulnerability for the stress-related somatic syndromes and also to contribute to symptom expression and severity. Understanding the relationship between violence, stress, and somatic syndromes will help in clarifying the consequences of violence exposure to long-term health and health-related quality of life.

Pain acceptance moderates the relation between pain and negative affect in female osteoarthritis and fibromyalgia patients.

Kratz AL, Davis MC, Zautra AJ.
.

Background: Chronic pain is often intractable despite advanced medical and psychotherapeutic treatments. Pain acceptance is emerging as a promising complement to control-based pain management strategies and a likely approach to maintaining quality of life for chronic pain patients.

Purpose: This theoretically based analysis of an existing database examined the extent to which pain acceptance predicted weekly reports of positive affect (PA) and negative affect (NA), and the relations of pain severity to both PA and NA.

Methods: Participants were women, 36 with osteoarthritis and 86 with fibromylagia, who completed an initial assessment for demographics, pain catastrophizing, and pain acceptance, and 2 to 12 weekly assessments of pain severity, PA, and NA.

Results: Multilevel modeling analyses indicated that pain acceptance was related to higher levels of PA but was unrelated to NA. Furthermore, pain acceptance moderated the relation of NA and pain severity, such that expected increases in NA during pain exacerbations were buffered by higher levels of pain acceptance.

Conclusions: These findings suggest that pain patients with greater capacity to accept pain may be emotionally resilient in managing their condition.

PURPOSE:: To evaluate the effects of a 12-wk period of aquatic training and subsequent detraining on health-related quality of life (HRQOL) and physical fitness in females with fibromyalgia.

METHODS:: Thirty-four females with fibromyalgia were randomly assigned into two groups: an exercise group, who exercised for 60 min in warm water, three times a week (N = 17); and a control group, who continued their habitual leisure-time activities (N = 17). HRQOL was assessed using the Short Form 36 questionnaire and the Fibromyalgia Impact Questionnaire. Physical fitness was measured using the following tests: Canadian Aerobic Fitness, hand grip dynamometry, 10-m walking, 10-step stair climbing, and blind one-leg stance. Outcomes were measured at baseline, after treatment, and after 3 months of detraining.

RESULTS:: After 12 wk of aquatic exercise, significant positive effects of aquatic training were found in physical function, body pain, general health perception, vitality, social function, role emotional problems and mental health, balance, and stair climbing. After the detraining period, only the improvements in body pain and role emotional problems were maintained.

CONCLUSION:: The present water exercise protocol improved some components of HRQOL, balance, and stair climbing in females with fibromyalgia, but regular exercise and higher intensities may be required to preserve most of these gains.

Cognitive functioning and aging in women.

Badgio PC, Worden BL.

pbadgio@msn.com

Deficits in cognitive function may impact one’s ability to attend to stimuli, think clearly, reason, and remember. Impaired cognitive function is a common complaint among older women presenting for treatment in both mental health and medical care settings, and differential diagnosis of type and extent of cognitive impairment is important for appropriate treatment planning and prognosis. Although overall gender differences in prevalence of cognitive dysfunction are minimal, it is important when treating older women to take into account unique challenges they face in the aging process that impact the cause, type and extent of cognitive complaints with which they present in clinical settings. The current paper provides an overview to guide accurate diagnosis, particularly in women, of different types of cognitive impairment under the broad category of dementias, including Alzheimer’s, Lewy Body Disease, Vascular Dementia, and due to general medical conditions such as coronary artery bypass surgery, head injury, menopause, hypothyroidism, breast cancer treatment, Fibromyalgia, and chronic fatigue. In addition, emotional factors such as depression in older female patients complicate differential diagnosis of cognitive impairment and must be addressed. Given the multiplicity of causes of cognitive difficulties for women across the life span, careful assessment is crucial; the current paper reviews assessment strategies to prepare an integrated, biopsychosocial strategy for identifying particular cognitive deficits and related psychological and medical problems. In addition, prognostic indicators and treatment planning are discussed to help the practitioner organize an empathic, reasoned and multifaceted treatment approach to maximize recovery, minimize deterioration, and manage symptoms for older women in the context of their social support system and living environment.

Striatal grey matter increase in patients suffering from fibromyalgia – A voxel-based morphometry study.

Fibromyalgia (FM), among other chronic pain syndromes, such as chronic tension type headache and atypical face pain, is classified as a so-called dysfunctional pain syndrome. Patients with fibromyalgia suffer from widespread, “deep” muscle pain and often report concomitant depressive episodes, fatigue and cognitive deficits. Clear evidence for structural abnormalities within the muscles or soft tissue of fibromyalgia patients is lacking. There is growing evidence that clinical pain in fibromyalgia has to be understood in terms of pathological activity of central structures involved in nociception. We applied MR-imaging and voxel-based morphometry, to determine whether fibromyalgia is associated with altered local brain morphology. We investigated 20 patients with the diagnosis of primary fibromyalgia and 22 healthy controls. VBM revealed a conspicuous pattern of altered brain morphology in the right superior temporal gyrus (decrease in grey matter), the left posterior thalamus (decrease in grey matter), in the left orbitofrontal cortex (increase in grey matter), left cerebellum (increase in grey matter) and in the striatum bilaterally (increase in grey matter). Our data suggest that fibromyalgia is associated with structural changes in the CNS of patients suffering from this chronic pain disorder. They might reflect either a consequence of chronic nociceptive input or they might be causative to the pathogenesis of fibromyalgia. The affected areas are known to be both, part of the somatosensory system and part of the motor system.

Further legitimization of fibromyalgia as a true medical condition

Elsevier Health Sciences

Philadelphia, June 25, 2007 — Fibromyalgia, a chronic, widespread pain in muscles and soft tissues accompanied by fatigue, is a fairly common condition that does not manifest any structural damage in an organ. Twenty-five years ago, Muhammad B. Yunus, MD, and colleagues published the first controlled study of the clinical characteristics of fibromyalgia syndrome. That seminal article, published in Seminars in Arthritis and Rheumatism, led directly to formal recognition of this disease by the medical community. In the June 2007 issue of Seminars in Arthritis and Rheumatism, Dr. Yunus once again makes an enormous contribution to the field of chronic pain and fatigue by meticulously synthesizing and interpreting the extensive body of scientific literature on fibromyalgia and his own insights into the concept of central sensitivity syndromes (CSS).

Fibromyalgia, affecting approximately 2% of the US population, is an example of a class of maladies called CSS. These diseases are based on neurochemical abnormalities and include irritable bowel syndrome, migraine and restless legs syndrome.

Incorporating a critical review of over 225 publications and the author’s broad experience in fibromyalgia and related diseases, Dr. Yunus describes 13 separate conditions that are related to central sensitization (CS), where the central nervous system (spinal cord and brain) becomes extremely sensitized on certain parts of the body, so that even mild pressure or touch would cause much pain. Such hypersensitivity may also be associated with other symptoms such as poor sleep and fatigue.

According to Dr. Yunus, “CSS are the most common diseases that are based on real neurochemical pathology and cause real pain and suffering. In some patients stress and depression may contribute to the symptoms but they are all based on objective changes in the central nervous system.”

Dr. Norman L. Gottlieb, Editor of Seminars in Arthritis and Rheumatism, believes that this article “advances our understanding of fibromyalgia, unifies and advances concepts, and suggests that this and several other common disorders have much in common in terms of their biopsychosocial development. This, hopefully, will expand both clinical and research interest in this group of diseases and lead to advances in therapy for many of them.”

In an accompanying editorial John B. Winfield, MD, comments, “Without question, Muhammad Yunus is the father of our modern view of fibromyalgia…. Yunus, who took a rather more biological approach to fibromyalgia in the past, now emphasizes a biopsychosocial perspective. In my view, this is tremendously important because it is the only way to synthesize the disparate contributions of such variables as genes and adverse childhood experiences, life stress and distress, posttraumatic stress disorder, mood disorders, self-efficacy for pain control, catastrophizing, coping style, and social support into the evolving picture of central nervous system dysfunction vis-a-vis chronic pain and fatigue ….Science and medicine now have a rational scaffolding for understanding and treating chronic pain syndromes previously considered to be ‘functional’ or ‘unexplained.’ …Neuroscience research will continue to reveal the mechanisms of CS, but only if informed through a biopsychosocial perspective and with the interdisciplinary collaboration of basic scientists, psychologists, sociologists, epidemiologists, and clinicians.”

Dr. Yunus concludes that CSS is an important new concept that embraces the biopsychosocial model of disease. He advocates further critical studies to fully test this concept which seems to have important significance for new directions for research and patient care involving physician and patient education. “Each patient, irrespective of diagnosis,” says Dr. Yunus, “should be treated as an individual, considering both the biological and psychosocial contributions to his or her symptoms and suffering.”

Functional somatic syndrome: how it could be relevant to rheumatologists.

1: Mod Rheumatol. 2007;17(3):179-84. Epub 2007 Jun 20.

Functional somatic syndrome (FSS) is defined as a group of related syndromes characterized more by symptoms, suffering, and disability than by structural or functional abnormality. The diagnostic criteria and/or symptoms of FSS often overlap, and co-morbidity is commonly found among the diseases of FSS. For example, patients with irritable bowel syndrome often suffer from chronic pain, and a high percentage of co-morbidity can be found with fibromyalgia. Accumulating evidence indicates the presence of visceral and somatic hyperalgesia in FSS as a common feature, and the central sensitization mechanism has been suggested to play an important role in the pathophysiology of FSS. In the present article, the authors introduce the concept of FSS focusing on its possible relevance to rheumatology in terms of pain perception. A possible implication of mast cells and proteinase-activated receptor-2 (PAR-2) in FSS is also reviewed.

INTRODUCTION: The clinical experience that subjects claiming retirement pension tend to aggravate their symptoms in psychometric tests has not yet, to our knowledge, been empirically tested.

METHODS: Pain intensities and the summary score of the Pain Disability Index (PDI) of 83 consecutive subjects diagnosed with fibromyalgia syndrome (FMS) claiming retirement pension in medical assessment for the German Social Court were compared with 43 consecutive patients diagnosed with FMS of an outpatient pain department who did not claim retirement pension. Moreover, the relative predictive value of claiming retirement pension compared to other potential sociodemographic and clinical predictors of pain intensity and self-assessed disability was determined.

RESULTS: Subjects claiming retirement pension within the context of medical testimony stated higher pain intensities and disabilities than patients who did not claim retirement pension (PFMS Global News
