Abstract: This review covers reports published in the last 5 years on the anti-inflammatory activities of all classes of cannabinoids, including phytocannabinoids such as tetrahydrocannabinol and cannabidiol, synthetic analogs such as ajulemic acid and nabilone, the endogenous cannabinoids anandamide and related compounds, namely, the elmiric acids, and finally, noncannabinoid components of Cannabis that show anti-inflammatory action. It is intended to be an update on the topic of the involvement of cannabinoids in the process of inflammation. A possible mechanism for these actions is suggested involving increased production of eicosanoids that promote the resolution of inflammation. This differentiates these cannabinoids from cyclooxygenase-2 inhibitors that suppress the synthesis of eicosanoids that promote the induction of the inflammatory process.

Abstract: Primary fibromyalgia, a poorly-understood chronic pain syndrome, is characterized by widespread musculoskeletal pain, nonrestorative sleep, fatigue, psychological distress, and specific regions of localized tenderness, all in the absence of otherwise apparent organic disease. While the etiology of fibromyalgia is unclear, accumulating data suggest that disordered central pain processing likely plays a role in the pathogenesis of symptoms. Although various pharmacological treatments have been studied and espoused for treating fibromyalgia, no single drug or group of drugs has proved to be particularly useful in treating fibromyalgia patients as a whole, and only one drug to date has earned U.S. Food and Drug Administration approval for treating the syndrome in the United States. This review critically and systematically evaluates clinical investigations of medicinal and nonmedicinal treatments for fibromyalgia dating from 1970 to 2007.

Abstract: PURPOSE OF REVIEW: The purpose of this article is to describe the application of basic exercise principles to individuals with fibromyalgia to encourage clinicians to discuss with their patients ways of becoming more physically active. RECENT FINDINGS: The goals of increased physical activity and exercise for individuals with fibromyalgia are to improve or maintain general fitness, physical function, emotional well being, symptoms and overall health, and provide them with a feeling of control over their well being. Describing ways of increasing activity through home, work and leisure-related tasks or exercise provides a universal approach to increasing physical activity that applies to individuals with fibromyalgia and fits a counseling model of health behavior familiar to clinicians. The patient-clinician relationship provides a unique opportunity for health professionals to counsel individuals with fibromyalgia to become and remain more physically active. SUMMARY: Regular physical activity and exercise has numerous physical, psychological, and functional benefits for individuals with fibromyalgia and should be included in treatment plans. Clinicians can help patients adopt a more physically active lifestyle through targeted discussions, support and consistent follow up.

Abstract: As incidence of chronic hepatitis C (CHC) in the United States increases, management of physical and psychological symptoms over the long term becomes crucial. Research has shown meditation to be a valuable tool in reducing such symptoms for various chronic illnesses. In particular, the Mindfulness-Based Stress Reduction (MBSR) program offers curriculum that has been shown to influence both physiology and perception of disease states. Although there has been no direct research to date on the effectiveness of the MBSR program for CHC, several studies have shown significant findings affecting other chronic conditions, including heart disease, fibromyalgia, and HIV. The purpose of this literature review is to examine recent research, summarize findings, and indicate appropriate inclusion of MBSR as a primary, secondary, and tertiary treatment option in conjunction with biomedical care for those diagnosed with CHC. Thusly, nurses can better inform their clients with this condition.

Abstract: Vitamin D(3) (cholecalciferol) sufficiency is essential for maximising bone health. Vitamin D enhances intestinal absorption of calcium and phosphorus. The major source of vitamin D for both children and adults is exposure of the skin to sunlight. Season, latitude, skin pigmentation, sunscreen use, clothing and aging can dramatically influence the synthesis of vitamin D in the skin. Very few foods naturally contain vitamin D or are fortified with vitamin D. Serum 25-hydroxyvitamin D [25(OH)D; calcifediol] is the best measure of vitamin D status. Vitamin D deficiency [as defined by a serum 25(OH)D level of <50 nmol/L (<20 ng/mL)] is pandemic. This deficiency is very prevalent in osteoporotic patients. Vitamin D deficiency causes osteopenia, osteoporosis and osteomalacia, increasing the risk of fracture. Unlike osteoporosis, which is a painless disease, osteomalacia causes aching bone pain that is often misdiagnosed as fibromyalgia or chronic pain syndrome or is simply dismissed as depression. Vitamin D deficiency causes muscle weakness, increasing the risk of falls and fractures, and should be aggressively treated with pharmacological doses of vitamin D. Vitamin D sufficiency can be sustained by sensible sun exposure or ingesting at least 800-1000 IU of vitamin D(3) daily. Patients being treated for osteoporosis should be adequately supplemented with calcium and vitamin D to maximise the benefit of treatment.

Abstract: The pharmacologic management of fibromyalgia is based on the emerging evidence that pain in this disorder is primarily related to central pain sensitization. There is strong evidence that tricyclic antidepressants are effective, and moderate evidence for the effectiveness of serotonin reuptake inhibitors and dual serotonin-norepinephrine reuptake inhibitors. Recent work suggests that the anti-seizure medications pregabalin and gabepentin are also effective. The only analgesic demonstrated to be helpful is tramadol.

Abstract: Vitamin D inadequacy is pandemic among rehabilitation patients in both inpatient and outpatient settings. Male and female patients of all ages and ethnic backgrounds are affected. Vitamin D deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes the painful bone disease osteomalacia, and worsens proximal muscle strength and postural sway. Vitamin D inadequacy can be prevented by sensible sun exposure and adequate dietary intake with supplementation. Vitamin D status is determined by measurement of serum 25-hydroxyvitamin D. The recommended healthful serum level is between 30 and 60 ng/mL. 25-Hydroxyvitamin D levels of >30 ng/mL are sufficient to suppress parathyroid hormone production and to maximize the efficiency of dietary calcium absorption from the small intestine. This can be accomplished by ingesting 1000 IU of vitamin D(3) per day, or by taking 50,000 IU of vitamin D(2) every 2 weeks. Vitamin D toxicity is observed when 25-hydroxyvitamin D levels exceed 150 ng/mL. Identification and treatment of vitamin D deficiency reduces the risk of vertebral and nonvertebral fractures by improving bone health and musculoskeletal function. Vitamin D deficiency and osteomalacia should be considered in the differential diagnosis of patients with musculoskeletal pain, fibromyalgia, chronic fatigue syndrome, or myositis. There is a need for better education of health professionals and the general public regarding the optimization of vitamin D status in the care of rehabilitation patients.

Abstract: In this article, non-neurologic causes of neck and back pain are reviewed. Musculoskeletal pain generators include muscle, tendon, ligament, intervertebral disc, articular cartilage, and bone. Disorders that can produce neck and back pain include muscle strain, ligament sprain, myofascial pain, fibromyalgia, facet joint pain, internal disc disruption, somatic dysfunction, spinal fracture, vertebral osteomyelitis, and polymyalgia rheumatica. Atlantoaxial instability and atlanto-occipital joint pain are additional causes of neck pain. Back pain resulting from vertebral compression fracture, Scheuermann's disease, spondylolysis and spondylolisthesis, pregnancy, Baastrup's disease, sacroiliac joint dysfunction, and sacral stress fracture is discussed.

Abstract: Painful bladder syndrome/interstitial cystitis (PBS/IC) is a disease of unknown aetiology, characterised by severe pressure and pain in the bladder area or lower pelvis that is frequently or typically relieved by voiding, along with urgency or frequency of urination in the absence of urinary tract infections. PBS/IC occurs primarily in women, is increasingly recognised in young adults, and may affect as many as 0.1-1% of adult women. PBS/IC is often comorbid with allergies, endometriosis, fibromyalgia, irritable bowel syndrome and panic syndrome, all of which are worsened by stress. As a result, patients may visit as many as five physicians, including family practitioners, internists, gynaecologists, urologists and pain specialists, leading to confusion and frustration. There is no curative treatment; intravesical dimethyl sulfoxide, as well as oral amitriptyline, pentosan polysulfate and hydroxyzine have variable results, with success more likely when these drugs are given together. Pilot clinical trials suggest that the flavonoid quercetin may be helpful. Lack of early diagnosis and treatment can affect outcomes and leads to the development of hyperalgesia/allodynia.

Abstract: PURPOSE OF REVIEW: Fibromyalgia is a common chronic pain disorder characterized by complex symptomatology and few consistently effective treatments. The purpose of this review is to highlight the recent literature from April 2005 through September 2006 involving treatment options. RECENT FINDINGS: Prior evidence suggests that medication and self-management approaches to care can improve symptoms, function and well-being in this patient population. Recent studies examining the efficacy of two serotonin and norepinephrine-reuptake inhibitors--duloxetine and milnacipran--and the anticonvulsant pregabalin are encouraging. Studies evaluating different forms of exercise continue to support the belief that increased physical activity is an essential component of any treatment plan for the patient with fibromyalgia. Three studies added to the understanding of treatment adherence. Finally, three studies evaluating the efficacy of acupuncture in the treatment of fibromyalgia showed conflicting results, but added to the knowledge needed for clinicians to have substantive conversations with patients. SUMMARY: Recent studies support the recommendation of a multimodal approach to treatment involving individualized, evidence-based pharmacotherapy and self-management. Treatment goals should include the improvement of symptoms, primarily pain and sleep, and the promotion of positive health behaviors with the aim of improving physical function and emotional well-being.

Abstract: Low back pain is one of the complaints most commonly seen in the clinical setting. Correctly or incorrectly, these patients are often given the diagnosis of fibromyalgia, myofascial pain syndrome, disk herniation, or some other label. It is important to recognize the soft tissue causes of low back pain and understand how they can be most appropriately diagnosed and managed. Nonligamentous disorders of the low back region may occur in isolation or in combination with underlying discogenic, ligamentous, and facet-mediated causes of pain. Therefore, in order to fully evaluate and treat a patient with low back pain, it is necessary to consider and address these soft tissue conditions. This paper reviews soft tissue causes of low back pain and discusses how they are most appropriately diagnosed and managed.

Abstract: INTRODUCTION: Insomnia is associated with a number of medical and psychiatric disorders, including chronic pain and clinical depression. Until recently, it was assumed that effective treatment of the underlying medical condition would also correct the sleep disturbance. However, some evidence indicates that treatment of secondary or comorbid insomnia should be considered separately from, and perhaps in addition to, optimizing treatment of the primary condition. METHODS: This article reviews the extant literature to examine the impact of secondary and comorbid insomnia on the patient, and on healthcare economics, in the primary care setting, and discusses current diagnostic and treatment approaches. A MEDLINE search was performed for literature published from 1980 to 2005, and retrieved randomized, controlled clinical trials and key review articles for the conditions most often accompanied by secondary insomnia: depression, chronic pain, and menopause/perimenopause. The search terms included those for commonly used pharmacologic treatments and behavioral therapy. RESULTS: Due to the paucity of clinical trial data in secondary insomnia patients, physicians have had to rely on evidence derived from primary insomnia trials. These data indicate that hypnotic medications are effective in treating sleep onset insomnia. However, few of these agents are effective against the most commonly occurring insomnia symptom - poor sleep maintenance - and many are associated with problematic residual sedation. Nevertheless, the cost of not treating these insomnia symptoms is often greater than the treatment inadequacies. Physicians should thus consider treating what they perceive as secondary insomnia with one of the available forms of therapy. CONCLUSION: Patients experiencing sleep problems associated with a potential medical or psychiatric primary condition would likely benefit from increased physician awareness of secondary insomnia and the subsequent increased attention to diagnosing and treating this prevalent condition. Recommendations for managing secondary or comorbid insomnia in the primary care setting are discussed.

Abstract: Chronic muscle pain is a common complaint among patients who seek care for musculoskeletal disorders. A spectrum of clinical presentations exists, ranging from focal or regional complaints that usually represent myofascial pain syndromes to more wide spread pain that may meet criteria for a diagnosis of fibromyalgia. This article addresses the epidemiology, pathophysiology, and clinical management of myofascial pain syndrome and fibromyalgia. These conditions are challenging to treat and require physiatrists to be aware of the wide range of pharmacologic, rehabilitative,and psychosocial interventions that can be helpful.

Abstract: In general, there seems to be a reduction in some neuroendocrine and autonomic nervous system (ANS) responses to applied stresses in individuals who have fibromyalgia. This article presents an overview and discussion of these findings with respect to the role of the ANS and the neuroendocrine system in the response to stress, with emphasis on the hypothalamic-pituitary-adrenal axis and the possible implication to fibromyalgia.

Abstract: Characterized by chronic widespread joint and muscle pain, fibromyalgia is a syndrome of unknown etiology. The American College of Rheumatology's classification criteria for fibromyalgia include diffuse soft tissue pain of at least 3 months' duration and pain on palpation in at least 11 of 18 paired tender points. Symptoms are often exacerbated by exertion, stress, lack of sleep, and weather changes. Fibromyalgia is primarily a diagnosis of exclusion, established only after other causes of joint or muscle pain are ruled out. The initial workup for patients who present with widespread musculoskeletal pain should include a complete blood count, erythrocyte sedimentation rate, liver function tests, hepatitis C antibody, calcium, and thyrotropin. The musculoskeletal system, the neuroendocrine system, and the central nervous system, particularly the limbic system, appear to play major roles in the pathogenesis of fibromyalgia. The goal in treating fibromyalgia is to decrease pain and to increase function without promoting polypharmacy. Brief interdisciplinary programs have been shown to improve subjective pain. Fibromyalgia is a complex syndrome associated with significant impairment on quality of life and function and substantial financial costs. Once the diagnosis is made, providers should aim to increase patients' function and minimize pain. This can be accomplished through nonpharmacological ahd pharmacological interventions. With proper management, the rate of disability appears to be significantly reduced.

Abstract: The purpose of this review is to put into perspective the many health benefits of vitamin D and the role of vitamin D deficiency in increasing the risk of many common and serious diseases, including some common cancers, type 1 diabetes, cardiovascular disease, and osteoporosis. Numerous epidemiologic studies suggest that exposure to sunlight, which enhances the production of vitamin D(3) in the skin, is important in preventing many chronic diseases. Because very few foods naturally contain vitamin D, sunlight supplies most of our vitamin D requirement. 25-Hydroxyvitamin D [25(OH)D] is the metabolite that should be measured in the blood to determine vitamin D status. Vitamin D deficiency is prevalent in infants who are solely breastfed and who do not receive vitamin D supplementation and in adults of all ages who have increased skin pigmentation or who always wear sun protection or limit their outdoor activities. Vitamin D deficiency is often misdiagnosed as fibromyalgia. A new dietary source of vitamin D is orange juice fortified with vitamin D. Studies in both human and animal models add strength to the hypothesis that the unrecognized epidemic of vitamin D deficiency worldwide is a contributing factor of many chronic debilitating diseases. Greater awareness of the insidious consequences of vitamin D deficiency is needed. Annual measurement of serum 25(OH)D is a reasonable approach to monitoring for vitamin D deficiency. The recommended adequate intakes for vitamin D are inadequate, and, in the absence of exposure to sunlight, a minimum of 1000 IU vitamin D/d is required to maintain a healthy concentration of 25(OH)D in the blood.

Abstract: The economic burden of depression is substantial. The condition is highly prevalent, with both psychiatric and physical symptoms that often inflict pain. The chronic and often debilitating nature of depression results in costly medical therapies, as well as impaired workplace productivity. As a result, the overall economic burden of depression is comparable to that of serious physical illnesses, such as cancer and heart disease. This article presents an overview of the economic burden of depression and provides background on the relationship between depression and pain in this context. Research findings are also presented on the economic burden associated with a particular manifestation of pain among depressed patients, fibromyalgia. When painful physical symptoms accompany the already debilitating psychiatric and behavioral symptoms of depression, the economic burden that ensues for patients and their employers increases considerably. On purely economic grounds, more aggressive outreach may be warranted for patients with depression and comorbid pain to initiate treatment before symptoms are allowed to persist. However, more research is needed to assess the comprehensive economic impact that depression with painful physical symptoms can have on society.

Abstract: A Medline literature review found that the total number of medical articles dealing with fibromyalgia (FM) has increased 5-fold during the past decade. The percentage of articles devoted to FM in rheumatology journals has increased modestly, from 1.3 to 2.6%. There is a wide variability of the number of articles on FM among these rheumatology journals. Recently, nonrheumatology journals have been publishing more articles on FM.

Abstract: The office management of fibromyalgia (FM) is best determined by two variables: (1) the severity and complexity of each patient's symptoms, and (2) the specialization and interest of the treating physician. Because there are 6 to 10 million Americans with FM, most patient visits will be to the primary care physician. Rheumatologists, physiatrists, and other musculoskeletal specialists must work with primary care physicians to foster the early diagnosis and appropriate treatment of FM. Primary care physicians are faced with enormous challenges in caring for patients with chronic pain disorders like FM. Our managed health care system insists that patient encounters be brief. Specialty referrals are often discouraged. There is little if any reimbursement for patient education. FM treatment is labor-intensive. Therefore, optimal planning and use of precious office time and resources are most important. Rheumatologists should train our primary care colleagues to recognize FM. Many patients still go months or years before this common syndrome is diagnosed. Rheumatologists should also spearhead teaching primary care physicians the basic treatment principles of FM. If the diagnosis is made early, patients with FM in community practice do very well with simple management techniques. As consultants, rheumatologists should confirm the diagnosis of FM and suggest basic FM management. Some primary care providers or other specialists will be fully capable of bypassing this consultation, especially if the patient responds to simple management suggestions. Manpower surveys have not studied the cost-effectiveness of specialty care in FM. Rheumatologists should also assume the responsibility for the management of FM patients who have not responded to basic FM management. Additionally, some rheumatologists may wish to subspecialize in FM, a major career commitment to this perplexing disorder. These situations constitute advanced FM management.

Abstract: Fibromyalgia is a widespread chronic pain disorder that is characterized in part by central sensitization and increased pain response to peripheral nociceptive and non-nociceptive stimuli. Part of the comprehensive pain management of patients with fibromyalgia should include a thoughtful evaluation and search for peripheral pain generators that either are associated with fibromyalgia or are coincidentally present. The identification and treatment of these pain generators lessens the total pain burden, facilitates rehabilitation and decreases the stimuli for ongoing central sensitization.

Abstract: Fibromyalgia is a disorder of unknown etiology characterized by chronic, widespread musculoskeletal pain and symptoms such as fatigue, poor sleep, gastrointestinal complaints, and psychologic problems that are similar to those experienced by patients with hormone deficiencies. This review summarizes the available data on the neuroendocrine function in fibromyalgia, including data on hormone secretion, circadian phase, and autonomic nervous system function. Studies suggest that there may be lower activity of a number of hypothalamic-pituitary-peripheral gland axes and altered autonomic nervous system function in patients with fibromyalgia. These reductions in activity are mild to moderate and do not result from alterations in circadian rhythms. The reduced hormonal and autonomic responses appear to reflect an impairment in the hypothalamic or central nervous system response to stimuli rather than a primary defect at the level of the pituitary gland or the peripheral glands. A combination of multiple, mild impaired responses may lead to more profound physiologic and clinical consequences as compared with a defect in only one system, and could contribute to the symptoms of fibromyalgia.

Abstract: In humans, activation of the primary host defense system leads to increased or decreased NREM sleep quality, depending on the degree of early immune activation. Modest elevations of certain inflammatory cytokines are found during experimental sleep loss in humans and, in addition, relatively small elevations of cytokines are seen following commencement of pharmacological treatments with clozapine, a CNS active antipsychotic agent, known to have immunomodulatory properties. Cytokines such as TNF-alpha, its soluble receptors, and IL-6, present in the periphery and the CNS, comprise a link between peripheral immune stimulation and CNS-mediated behaviors and experiences such as sleep, sleepiness, and fatigue. The debilitating fatigue experienced in chronic fatigue syndrome and related diseases may also be related to altered cytokine profiles.

Abstract: Infection with B. burgdorferi can cause a large joint inflammatory arthritis in patients who have not been treated for early Lyme disease; the knee is the most common joint affected. The diagnosis depends on a history of known exposure to the spirochete, characteristic clinical features, and serologic studies (ELISA and Western blot) confirming exposure to the spirochete. In most patients, antibiotic therapy is curative, but in a smaller percentage of patients, the presence of the HLA-DR beta 1*0401 haplotype can trigger treatment-resistant arthritis, in which antibiotic therapy is ineffective; in these instances, remittive agents, such as hydroxychloroquine and methotrexate, are indicated. Arthroscopic synovectomy may be considered when antibiotic therapy is not curative. Fibromyalgia can follow infection with B. burgdorferi but is unresponsive to antibiotic therapy; it is treated with tricyclic antidepressants and an exercise program. Lyme arthritis is the only chronic inflammatory arthritis in which the specific cause is known and can be cured. As such, it serves as an excellent model with which to study the pathogenesis of more common inflammatory arthritides, such as rheumatoid arthritis.
