A 25-year-old woman was admitted in our hospital with back pain and both hip joint pain. Pain was abruptly occurred from the beginning of March 1990. Physical examination revealed wide spread pain (occipital area, both shoulder, lumber area, bilateral gluteal area, inguinal area, both Achilles-plantar area) and more than 12 tender points (occiput, trapezius, second rib, supraspinatus, gluteal, greater trochanter, hip joints, pubic bone). Laboratory examination showed no abnormal findings except ANF (1:160). Any examination including X-ray, bone scintigraphy, CT and MRI did not disclose spondylitis, sacroiliitis and enthesopathy. She was diagnosed as primary fibromyalgia/fibrositis syndrome. Treatment with maprotine hydrochloride (30 mg/day) and phenobarbital (120 mg/day) brought approximately 1/3 reduction of pain and tenderness. Psychoanalysis revealed that she had psychological conflicts against her parents and her colleagues at the work. EEG showed a borderline record with irregular basic pattern and 14 & 6 Hz positive burst at the sleep stage. Although the newly proposed criteria for the classification of fibromyalgia was proposed by ACR, fibromyalgia/fibrositis syndrome has been seldom discussed in the Japanese literature. As this syndrome is frequently associated with various rheumatic diseases, hypothyroidism and malignant diseases, we should pay much more attention to understand this syndrome.

Six conditions cause most of the neck pain complaints seen by primary care physicians: cervical muscle strain or sprain, torticollis, acceleration injury, myofascial pain dysfunction syndrome, and cervical osteoarthritis or rheumatoid arthritis. Most of them can be diagnosed and treated by the primary care physician. Of the more unusual causes, one should not miss a clinical fracture; a herniated cervical disc, spinal cord compression from a disc, or epidural tumor; infection of the disc or the vertebral body; subluxation of the vertebral bodies; or pain referred from the chest or mediastinal structures. MRI offers new opportunity for early diagnosis of myelopathy owing to OA or RA, vertebral osteomyelitis, and metastatic involvement of cervical vertebrae.

Pain catastrophizing, or characterizations of pain as awful, horrible and unbearable, is increasingly being recognized as an important factor in the experience of pain. The purpose of this investigation was to examine the association between catastrophizing, as measured by the Coping Strategies Questionnaire Catastrophizing Subscale, and brain responses to blunt pressure assessed by functional MRI among 29 subjects with fibromyalgia. Since catastrophizing has been suggested to augment pain perception through enhanced attention to painful stimuli, and heightened emotional responses to pain, we hypothesized that catastrophizing would be positively associated with activation in structures believed to be involved in these aspects of pain processing. As catastrophizing is also strongly associated with depression, the influence of depressive symptomatology was statistically removed. Residual scores of catastrophizing controlling for depressive symptomatology were significantly associated with increased activity in the ipsilateral claustrum (r = 0.51, P < 0.05), cerebellum (r = 0.43, P < 0.05), dorsolateral prefrontal cortex (r = 0.47, P < 0.05), and parietal cortex (r = 0.41, P < 0.05), and in the contralateral dorsal anterior cingulate gyrus (ACC; r = 0.43, P < 0.05), dorsolateral prefrontal cortex (r = 0.41, P < 0.05), medial frontal cortex (r = 0.40, P < 0.05) and lentiform nuclei (r = 0.40, P < 0.05). Analysis of subjects classified as high or low catastrophizers, based on a median split of residual catastrophizing scores, showed that both groups displayed significant increases in ipsilateral secondary somatosensory cortex (SII), although the magnitude of activation was twice as large among high catastrophizers. Both groups also had significant activations in contralateral insula, SII, primary somatosensory cortex (SI), inferior parietal lobule and thalamus. High catastrophizers displayed unique activation in the contralateral anterior ACC, and the contralateral and ipsilateral lentiform. Both groups also displayed significant ipsilateral activation in SI, anterior and posterior cerebellum, posterior cingulate gyrus, and superior and inferior frontal gyrus. These findings suggest that pain catastrophizing, independent of the influence of depression, is significantly associated with increased activity in brain areas related to anticipation of pain (medial frontal cortex, cerebellum), attention to pain (dorsal ACC, dorsolateral prefrontal cortex), emotional aspects of pain (claustrum, closely connected to amygdala) and motor control. These results support the hypothesis that catastrophizing influences pain perception through altering attention and anticipation, and heightening emotional responses to pain. Activation associated with catastrophizing in motor areas of the brain may reflect expressive responses to pain that are associated with greater pain catastrophizing.

Involvement of the musculoskeletal system is common if not universal in the clinical course of systemic lupus erythematosus (SLE). Joint involvement on the whole does not cause major erosive disease, however, recent developments in musculoskeletal imaging show clearly the presence of significant bony and soft tissue involvement. It might well explain the frequently observed discordance between the clinical signs and the articular symptoms assuming that fibromyalgia has been excluded. The clear demonstration of tendon involvement in SLE by MRI would merit considering tendonitis and tenosynovitis as candidates for inclusion in the diagnostic criteria.

Some chronic painful conditions including e.g. fibromyalgia, whiplash associated disorders, endometriosis, and irritable bowel syndrome are associated with generalized musculoskeletal hyperalgesia. The aim of the present study was to determine whether generalized deep-tissue hyperalgesia could be demonstrated in a group of patients with chronic low-back pain with intervertebral disc herniation. Twelve patients with MRI confirmed lumbar intervertebral disc herniation and 12 age and sex matched controls were included. Subjects were exposed to quantitative nociceptive stimuli to the infraspinatus and anterior tibialis muscles. Mechanical pressure (thresholds and supra-threshold) and injection of hypertonic saline (pain intensity, duration, distribution) were used. Pain intensity to experimental stimuli was assessed on a visual analogue scale (VAS). Patients demonstrated significantly higher pain intensity (VAS), duration, and larger areas of pain referral following saline injection in both infraspinatus and tibialis anterior. The patients rated significantly higher pain intensity to supra-threshold mechanical pressure stimulation in both muscles. In patients, the pressure pain-threshold was lower in the anterior tibialis muscle compared to controls. In conclusion, generalized deep-tissue hyperalgesia was demonstrated in chronic low-back pain patients with radiating pain and MRI confirmed intervertebral disc herniation, suggesting that this central sensitization should also be addressed in the pain management regimes.

Functional MRI blood oxygenation level dependent activation studies on patients who have fibromyalgia have demonstrated augmented sensitivity to painful pressure and the association of this augmentation with variables such as depression and catastrophizing and have also been used to evaluate the symptoms of cognitive dysfunction. Using a wide array of techniques, these studies have found differences in opioid receptor binding, in the concentration of metabolites associated with neural processing in pain-related regions, in functional brain networks, and in regional brain volume and white matter tracks. A common theme of all of these methods is that they provide information that may be pertinent to the otherwise unobservable and poorly treated symptoms of persistent widespread chronic pain.

Myofascial pain and fibromyalgia share a number of common features: the patient is uncomfortable; abnormalities can be detected on physical examination; and there is a lack of an objective means to either quantify or visualize their core features. This has undoubtedly contributed to a slowed acceptance of their importance by the medical community. Fortunately, the situation is beginning to change. Although progress may be somewhat slower in fibromyalgia, in which attention appears to focus on pain sensitivity and functional brain imaging, a number of approaches now seem promising in their ability to quantify the physical and biochemical characteristics of the taut bands and trigger points of myofascial pain. This review focuses on myofascial pain with an emphasis on the growing capability of MRI, microanalytic techniques, and ultrasonography to assess, quantitate, and even visualize the characteristics of these stigmatic lesions.

The primary symptom of fibromyalgia is widespread pain. This symptom is accompanied by secondary symptoms, such as cognitive difficulties and sensitivity to painful stimulation, and by numerous co-morbidities. The first neuroimaging studies addressed the primary symptom by examining differences between patients and controls using single-photon-emission-computed tomography (SPECT). Subsequent studies focussed on the secondary symptom of increased sensitivity to painful stimulation. Functional MRI (fMRI) studies using the blood-oxygen-level-dependent (BOLD) method to assess brain activation demonstrated augmented sensitivity to painful pressure and the association of this augmentation with variables such as depression and catastrophising. These studies have also assessed brain processes associated with cognitive dysfunction. Neuroimaging studies of fibromyalgia have now come full circle, using new techniques to provide information about differences that may relate to underlying mechanisms and the primary symptom of widespread pain. Using a wide array of techniques, these studies have found differences in opioid receptor binding, concentration of metabolites associated with neural processing in pain-related regions and differences in functional brain networks and in regional brain volume and in white-matter tracks. This array of neuroimaging techniques continues to provide increasing information about supraspinal mechanisms associated with fibromyalgia that will aid in diagnosis, including identification of diagnostic subgroups, the development of new efficacious treatments that address both causes and symptoms and the matching of patients to treatments.

Fibromyalgia (FM), characterized by chronic widespread pain, is known to be associated with heightened responses to painful stimuli and atypical resting-state functional connectivity among pain-related regions of the brain. Previous studies of FM using resting-state functional magnetic resonance imaging (rs-fMRI) have focused on intrinsic functional connectivity, which maps the spatial distribution of temporal correlations among spontaneous low-frequency fluctuation in functional MRI (fMRI) resting-state data. In the current study, using rs-fMRI data in the frequency domain, we investigated the possible alteration of power spectral density (PSD) of low-frequency fluctuation in brain regions associated with central pain processing in patients with FM. rsfMRI data were obtained from 19 patients with FM and 20 age-matched healthy female control subjects. For each subject, the PSDs for each brain region identified from functional connectivity maps were computed for the frequency band of 0.01 to 0.25 Hz. For each group, the average PSD was determined for each brain region and a 2-sample t test was performed to determine the difference in power between the 2 groups. According to the results, patients with FM exhibited significantly increased frequency power in the primary somatosensory cortex (S1), supplementary motor area (SMA), dorsolateral prefrontal cortex, and amygdala. In patients with FM, the increase in PSD did not show an association with depression or anxiety. Therefore, our findings of atypical increased frequency power during the resting state in pain-related brain regions may implicate the enhanced resting-state baseline neural activity in several brain regions associated with pain processing in FM.

[Purpose] Fibromyalgia syndrome (FMS) and cervical disc herniation (CDH) are a common diseases commonly encountered in physical therapy clinics. There are also patients who have both of these diseases. In this study we aim to investigated whether FMS is a risk factor for cervical disc herniation and the frequency of their coincident occurrence. [Subjects and Methods] Thirty-five patients having a primary FMS diagnosis according to the American Rheumatism Association criteria are taken into consideration and a control group were the subjects of this study. The two groups were compared with respect to cervical disc hernia using cervical region MRI. [Results] The distribution of disc hernia of 6 fibromyalgia patients who had cervical discopathy was: 16.6% C2-3, 16.6% C5-6, 16.6% C6-7, 33.3% C4-5, C5-6 (two levels in two patients) and 16.6% C4-5, C5-6, C7-1 (three levels in one patient) . The herniation directions were given as: central in 5 levels, right paramedian in 1 level, and left paramedian disc hernia in 1 level. There were 4 cervical disk hernia in the control group. The herniation direction were central in two, right paramedian in one, and left paramedian in one patient. [Conclusion] In this study, the existence of cervical disc herniation in fibromyalgia patients was found to be not different from the normal population.
