The aim of this paper is to assess whether patient-centred consultations are more effective than the usual style of consultations used by general practitioners with patients suffering from benign chronic musculoskeletal pain and fibromyalgia. It also seeks to evaluate the differential characteristics of these two clinical groups of symptoms. The study was designed as a cluster randomised and simple blind trial. Twenty general practitioners took part and 110 patients were recruited. Compared with patients who received the usual treatment from their family physician, those who received a patient-centred approach showed greater improvement after 1 year in terms of psychological distress (anxiety) and number of tender points, as well as showing positive trends in some important outcomes such as pain intensity. Significantly better results were observed in those patients suffering chronic pain than in those with fibromyalgia, particularly as regards associated symptoms, self-rated pain and physical mobility as measured by the Nottingham health profile.

Noxious stimuli and painful disorders interfere with sleep, but disturbances in sleep also contribute to the experience of pain.Chronic paroxysmal hemicrania and possibly cluster headaches are related to REM sleep. Whereas headache is associated with snoring and sleep apnea, morning headaches are not specific for any primary sleep disorder. Nevertheless, the management of the sleep disorder ameliorates both morning headache and migraine.Noxious stimuli administered into muscles during slow-wave sleep (SWS) result in decreases in delta and sigma but an increase in alpha and beta EEG frequencies during sleep. Noise stimuli that disrupt SWS result in unrefreshing sleep, diffuse musculoskeletal pain, tenderness, and fatigue in normal healthy subjects. Such symptoms accompany alpha EEG sleep patterns that often occur in patients with fibromyalgia. The alpha EEG patterns include phasic and tonic alpha EEG sleep as well as periodic K alpha EEG sleep or frequent periodic cyclical alternating pattern. Moreover, alpha EEG sleep, as well as sleep-related breathing disorder and periodic limb movement disorder, occur in some patients with fibromyalgia, rheumatoid arthritis and osteoarthritis. Depression and not alpha EEG sleep are features of somatoform pain disorder. Disturbances in sleep, pain behaviour and psychological distress influence return to work in workers who have suffered a soft tissue injury, e.g. low back pain. Patients with irritable bowel disorder have disturbed sleep and have increased REM sleep. In conclusion, there is a reciprocal relationship between sleep quality and pain. The recognition of disturbed or unrefreshing sleep influences the management of painful medical disorders.

A pathophysiological mechanism named "nociceptive sensory sensitisation" is introduced to explain part of the fibromyalgia pain syndrome as well as several local or regional long standing pain conditions like epicondylitis, chronic low back pain, whiplash associated disorder, temporomandibular pain disorder and trochanteritis. The article is based on a vast rheumatological clinical experience on patients presenting with local or wide-spread pain, and on literature studies. Sensory sensitisation describes a changed quality in sensory nerve pathways with hyperexcitability and facilitated transmission of nerve impulses to the sensory cortex. Sensory sensitisation should be considered as a pathophysiological reaction originating from tissues and organs exposed to "external" overload or trauma, either physical, chemical or biochemical. The sensitisation process is usually facilitated by "internal" psychological distress.

Fibromyalgia (FM) is currently defined as the presence of both chronic widespread pain (CWP) and the finding of 11/18 tender points on examination. Only about 20% of individuals in the population with CWP also have 11/18 tender points; these individuals are considerably more likely to be female, and have higher levels of psychological distress. There is no clear clinical diagnosis for the other 80% of individuals with less than 11/18 tender points, but it is likely that these persons, like FM patients, also have pain that is 'central' (i.e. not due to inflammation or damage of structures) rather than peripheral in nature. Research into FM has taught us a great deal about the confluence of neurobiological, psychological and behavioural factors that can cause chronic central pain. These conditions respond best to a combination of symptom-based pharmacological therapies, and non-pharmacological therapies such as exercise and cognitive behavioural therapy. In contrast to drugs that work for peripheral pain due to damage or inflammation (e.g. NSAIDs, corticosteroids), neuroactive compounds [especially those that raise central levels of noradrenaline (norepinephrine) or serotonin] are most effective for treating central pain.

Fibromyalgia (FM) is a common and complex condition, defined as long lasting, widespread musculoskeletal pain, in the presence of tender points (TPs) at specific anatomical sites. Dysautonomic and functional symptoms, such as orthostatic hypotension, tachycardia, effort intolerance, marked fatigue, sleep disorders, cognitive disturbances, psychological distress, paresthesias, headache, genitourinary manifestations, irritable bowel syndrome and bladder dyskinesia, frequently occur. The etiopathogenesis of FM is presently unknown, but nociceptor, autonomic and neuro-endocrine system dysfunctions have been found in patients. Since specific serological or instrumental markers of the syndrome are not yet identifiable, TP search is the only useful diagnostic hallmark. The development of an effective therapy of FM has hitherto been hampered by the incomplete knowledge of its pathogenic mechanisms. In this paper, the most recent information on FM is reviewed.

In women with fibromyalgia (FM), central nervous system (CNS) dysfunction in pain, mood, and sleep processes could be associated with changes in immune system indicators. The primary purpose of this study was to compare pain, psychological variables, subjective and objective sleep quality, lymphocyte phenotypes and activation markers, and natural killer activity (NKA) in midlife women with and without FM. A secondary purpose was to explore relationships among these variables in a step-wise regression. Subjects had pain pressure tender points assessed, completed a psychiatric interview and questionnaires (Beck Depression Inventory, SCL-90, Profile of Mood States, subjective sleep), and underwent polysomnograhic assessment for two consecutive nights. Lymphocyte phenotypes, activation markers, and NKA were assessed from blood drawn the morning after sleep laboratory night 2. Compared to controls, women with FM had lower pain thresholds, more psychological distress, higher depression scores, and reduced subjective and objective sleep quality. They also had fewer NK cells (p <.009) and more NK cells that expressed the IL-2 receptor (p <.04), but these differences were not statistically significant after correction for multiple comparisons. NKA was not statistically significantly lower in the women with FM compared to controls. In a multiple regression of age, tender point threshold, depression, psychological distress, and sleep efficiency, only the effect of group was significant (F = 5.479, p <.03) on NKA. In conclusion, we found little evidence to support the hypothesis that pain, mood, and sleep symptoms are associated with changes in the enumeration of peripheral lymphocytes or function in FM.

Myofascial pain syndrome is a painful musculoskeletal condition, and a quite common cause of chronic pain. It is characterized by the development of trigger points that are locally tender when active, and refer pain through specific patterns to other areas of the body. Its etiological factors are various; trauma, vertebral column diseases, systemic disorders, psychological distress, lack of motion, and chilling of the body parts. Myofascial pain syndrome may be misdiagnosed as arising from a visceral source especially if its probability is not kept in mind and a proper patient examination is lacking. Although there are many therapeutic approaches, trigger point injections can be diagnostic and therapeutic.

Chronic generalized pain (CGP) as one of the diagnostic criteria of fibromyalgia is a common condition amongst the populations of Western Europe and the USA. The prevalence of CGP in these countries is 10.7-13.2%. The etiology of CGP is unclear; however, several findings suggest that this is a process of somatization that masks affective disorders. There have been no studies of the epidemiology of CGP in Russia. The study was undertaken to determine the prevalence of CGP in the Yekaterinburg adult population and to examine the relationship of CGP to its demographic characteristics and affective disorders. A ostal cross-sectional population survey was conducted. This covered 159 persons (54 males and 105 females) aged 27 to 75 years who had been randomly selected from the election lists of Yekaterinburg residents. A questionnaire was posted to each participant in order to reveal whether a respondent had experienced pain a month before, to define its location, duration, severity, and to evaluate psychoemotional disorders. The response rate was 75.5% (120 replies). The prevalence of CGP was 13.3%. There was no relationship of the sex of a respondent to CGP. The latter was shown to be associated with age. There was also its significant association with psychoemotional disorders. CGP is a common condition in the Yekateringburg population, which occurs in every 8 adult residents, more frequently in those aged above 43 years. The individuals who suffer from CGP exhibit a high level of psychological distress.

Fibromyalgia is defined by widespread body pain, tenderness to palpation of tender point areas, and constitutional symptoms. The literature reports headache in about half of fibromyalgia patients. The current epidemiological study was designed to determine the prevalence and characteristics of headache in fibromyalgia patients. Treatment-seeking fibromyalgia patients were evaluated with measures for fibromyalgia, chronic headache, quality of life, and psychological distress. Multivariate analysis of variance (MANOVA) and t-tests were used to identify significant differences, as appropriate. A total of 100 fibromyalgia patients were screened (24 fibromyalgia without headache and 76 fibromyalgia with headache). International Headache Society diagnoses included: migraine alone (n = 15 with aura, n = 17 without aura), tension-type alone (n = 18), combined migraine and tension-type (n = 16), post-traumatic (n = 4), and probable analgesic overuse headache (n = 6). Fibromyalgia tender point scores and counts and most measures of pain severity, sleep disruption, or psychological distress were not significantly different between fibromyalgia patients with and without headache. As expected, the fibromyalgia patients with headache scored higher on the Headache Impact Test (HIT-6) (62.1 +/- 0.9 vs 48.3 +/- 1.6, p < 0.001). HIT-6 scores were >60 in 80% of fibromyalgia plus headache patients, representing severe impact from headache, and 56-58 in 4%, representing substantial impact. In summary, chronic headache was endorsed by 76% of treatment-seeking fibromyalgia patients, with 84% reporting substantial or severe impact from their headaches. Migraine was diagnosed in 63% of fibromyalgia plus headache patients, with probable analgesic overuse headache in only 8%. General measures of pain, pain-related disability, sleep quality, and psychological distress were similar in fibromyalgia patients with and without headache. Therefore, fibromyalgia patients with headache do not appear to represent a significantly different subgroup compared to fibromyalgia patients without headache. The high prevalence and significant impact associated with chronic headache in fibromyalgia patients, however, warrants inclusion of a headache assessment as part of the routine evaluation of fibromyalgia patients.

In clinic studies, altered hypothalamic-pituitary-adrenal (HPA) axis function has been associated with fibromyalgia, a syndrome characterised by chronic widespread body pain. These results may be explained by the associated high rates of psychological distress and somatisation. We address the hypothesis that the latter, rather than the pain, might explain the HPA results. A population study ascertained pain and psychological status in subjects aged 25 to 65 years. Random samples were selected from the following three groups: satisfying criteria for chronic widespread pain; free of chronic widespread pain but with strong evidence of somatisation ('at risk'); and a reference group. HPA axis function was assessed from measuring early morning and evening salivary cortisol levels, and serum cortisol after physical (pain pressure threshold exam) and chemical (overnight 0.25 mg dexamethasone suppression test) stressors. The relationship between HPA function with pain and the various psychosocial scales assessed was modelled using appropriate regression analyses, adjusted for age and gender. In all 131 persons with chronic widespread pain (participation rate 74%), 267 'at risk' (58%) and 56 controls (70%) were studied. Those in the chronic widespread pain and 'at risk' groups were, respectively, 3.1 (95% CI (1.3, 7.3)) and 1.8 (0.8, 4.0) times more likely to have a saliva cortisol score in the lowest third. None of the psychosocial factors measured were, however, associated with saliva cortisol scores. Further, those in the chronic widespread pain (1.9 (0.8, 4.7)) and 'at risk' (1.6 (0.7, 3.6)) groups were also more likely to have the highest serum cortisol scores. High post-stress serum cortisol was related to high levels of psychological distress (p = 0.05, 95% CI (0.02, 0.08)). After adjusting for levels of psychological distress, the association between chronic widespread pain and post-stress cortisol scores remained, albeit slightly attenuated. This is the first population study to demonstrate that those with established, and those psychologically at risk of, chronic widespread pain demonstrate abnormalities of HPA axis function, which are more marked in the former group. Although some aspects of the altered function are related to the psychosocial factors measured, we conclude that the occurrence of HPA abnormality in persons with chronic widespread pain is not fully explained by the accompanying psychological stress.
