Seven girls between 8.6 and 17.7 years of age were treated for symptoms of juvenile primary fibromyalgia syndrome (JPFS) using cognitive-behavioral techniques (progressive muscle relaxation, guided imagery) aimed at reducing pain and facilitating sleep, as well as strategies aimed at increasing mastery over the pain and improving mood. Patients satisfying diagnostic criteria for JPFS based on the presence of chronic diffuse musculoskeletal pain lasting at least 3 months (mean = 9.4, SD = 8.28) and a minimum of 5 characteristic soft tissue trigger and/or tender points with absence of synovitis, were referred for intervention. Results indicated that in the majority of patients, such techniques were effective in reducing pain and facilitating improved functioning.

Using 31P nuclear magnetic resonance, the following parameters were determined in the resting musculus erector spinae of five patients suffering from chronic low back pain, five patients with fibromyalgia, and five healthy controls: Inorganic phosphate (Pi), phosphocreatine (PCr), ATP gamma, ATP alpha, ATP beta. The intracellular pH was derived from the chemical shift of Pi referenced to the PCr resonance. In addition, the Pi-Index was calculated according to the formula: Pi/(Pi + PCr). We discovered a tendency towards a shift of the Pi resonance in the alcalic direction, which was the larger, the stronger muscle spasm was found on palpation. The pH showed the most reliable relationship to the clinical status of muscle spasm. The surprising finding that there is no acidification within the spasmed muscle indicates that generalized hypoxia does not exist in this tissue. This has already been shown with PO2 measurements. An intracellular acidification is only recorded during maximal isometric contraction. Thus, ischemia cannot be responsible for pain experienced during muscle spasm.

Generalized tendomyopathy (GTM), or fibromyalgia (FM), is a disease characterized by wide-spread pain in the musculoskeletal system which usually begins at a single site, e.g., as low-back pain or cervical syndrome, and develops into generalized pain over months or years. The disorder affects primarily women, beginning around the age of 35 and reaching its peak during or after the menopause. Its etiology is still unknown. Secondary forms are observed particularly in rheumatoid arthritis. In order to get more information on FM we determined the local metabolic rate of glucose in vivo in the skeletal muscle (lumbar region) with dynamic 18F-FDG positron emission tomography (PET). 2 healthy volunteers and 6 female patients with FM reaching in age from 31 to 53 years were scanned. As 18F-FDG PET scanning is a metabolic tool, it is crucial to observe standardized conditions of metabolic steady-state. We used, therefore, the hyperinsulinemic euglycemic insulin clamp technique to stimulate the myogenic glucose uptake under stable plasma-glucose levels. The local metabolic rates of glucose utilization were estimated with a non-linear least squares fit on the 3 compartment 18F-FDG-model. A lumped constant of 0.67 was assumed. Under glucose clamp conditions patients with FM showed a significantly (p < 0.001) lower metabolic rate of glucose (4.3 +/- 1.1) mumol/100 g tissue/min compared with normal volunteers (8.5 +/- 2.3 mumol/100 g/min). Due to a significantly (p < 0.005) increased glucose backflow from tissue into the vascular space (k2 in the kinetic model) the rate of phosphorylation was markedly reduced in patients with FM.(ABSTRACT TRUNCATED AT 250 WORDS)

We prospectively studied 47 consecutive patients with either seasonal or perennial allergic rhinitis or nonallergic rhinitis in a general allergy clinic. A diagnostic questionnaire was administered for symptoms of rhinitis and fibromyalgia, and patients were examined for tender points. A history of congestion was present in 91%, rhinorrhea in 87%, and postnasal drip in 83%. Forty-nine percent had a history of diffuse, aching pain, or tiredness for at least 3 months; 49% percent had 11 or more tender points; and 38% had both a history of widespread pain plus 11 or more tender points (the 1990 criteria of the American College of Rheumatology for fibromyalgia). This frequency is much higher than the expected 4 to 5% prevalence of fibromyalgia in a general population. Seventy-nine percent of all subjects were skin-test positive to inhalant allergens, but positive skin tests alone did not correlate with the number of tender points or criteria for fibromyalgia. Rhinitis, rather than atopy, is associated with fibromyalgia and may be an underdiagnosed, but important causative factor.

Primary fibromyalgia may involve an anomaly in the metabolism of serotonin responsible for the sleep disorders and diffuse pain. Effectiveness of an agent with pure serotonin-agonist properties (fluoxetin hydrochloride) was evaluated in 23 patients during a three-month open study. Treatment had no effect on pain severity, number of tender sites, or pain score. Sleep disorders improved and 57% of patients believed the treatment was effective. Adverse events were recorded in 43.4% of patients, with the most common being nausea (21.7%). Effectiveness and tolerance of fluoxetin hydrochloride in fibromyalgia are mediocre. A double-blind placebo-controlled trail versus a placebo is needed to clarify these preliminary findings.

Two studies were conducted to characterize the pain of fibromyalgia syndrome (FMS); to compare it to rheumatoid arthritis (RA) pain; and to examine the relationships between depression, pain extent, and pain description. Two methods of administering the McGill Pain Questionnaire (MPQ) were used. When the MPQ was administered in the standard manner, FMS pain could not be distinguished from RA pain. When participants were allowed to select as many words from an adapted MPQ as they wished, significant differences in word choice emerged. Depression and pain extent were major predictors of group differences in the evaluation of pain. However, depression scores contributed only 50% of the explanation for the differences in pain extent, with group membership contributing the other 50%. These findings suggest that the character and extent of pain in FMS are at least partially due to peripheral sensory components and not simply centrally controlled pain amplification secondary to depression.

Between 1982 and 1990, 81 children with localized or diffuse musculoskeletal pain, for which no cause could be found were seen in a pediatric rheumatology clinic. Forty-one children had localized idiopathic pain and 40 had diffuse idiopathic pain. Twenty-four of the patients with localized idiopathic pain fulfilled criteria for definite reflex neurovascular dystrophy. Thirty-five patients with diffuse idiopathic pain fulfilled criteria for fibromyalgia. Four patients with localized idiopathic pain (10%) developed diffuse idiopathic pain during followup; four patients with diffuse idiopathic pain (10%) had a history of localized idiopathic pain and one patient had previously been diagnosed as having Tietze's syndrome. Recurrences or persistence of pain was very common. Many children had potentially important stressors including single parent families, histories of sexual abuse, and learning difficulties. Idiopathic musculoskeletal pain is a common cause of referral to a pediatric rheumatology clinic and is often associated with significant morbidity.

The aim of this study was to describe which complaints patients themselves regard as the cause of sickness certification. During one week in April 1986, 1,379 patients in Buskerud county, Norway, filled in a form after receiving an initial certificate of illness or a continuation certificate from a general practitioner. International Classification of Primary Care (ICPC) no. 1-29 was used to classify the patients' symptoms and complaints. More than half of the patients (53%) considered pain in the musculoskeletal system, particularly back pain (22%), as the reason for their sickness certification. Physical work load was assumed to be a contributory cause to the complaints by 66% of the patients certified sick because of back pain, 58% of those certified sick due to cervical spine and shoulder symptoms, and 72% of those with myalgia, fibrositis (ICPC no. L18, L19). 29% of the patients meant that their health problems could have been prevented, and 15% reported that they could have continued work if their jobs had been adjusted because of their condition.

Pressure pain thresholds and pressure pain tolerances on non-trigger-point muscle and bone were measured with a dolorimeter in 46 female patients with primary fibromyalgia and in 50 healthy women of the same age. The pressure pain thresholds and the pressure pain tolerances on both muscle and bone were lower in the fibromyalgia patients than in the healthy controls. All the differences were statistically highly significant, though there was a certain degree of overlapping between the patients and the controls. It is concluded that patients with primary fibromyalgia have a generalized amplification of pain sensitivity, a sign that might be useful in the diagnosis of fibromyalgia.

The efficacy and tolerability of 5-hydroxy-L-tryptophan (5-HTP) were studied in an open 90-day study in 50 patients affected by primary fibromyalgia syndrome. When all the clinical variables studied throughout the trial (number of tender points, anxiety, pain intensity, quality of sleep, fatigue) were compared with baseline results, they all showed a significant improvement (P less than 0.001). The overall evaluation of the patient condition assessed by the patient and the investigator indicated a 'good' or 'fair' clinical improvement in nearly 50% of the patients during the treatment period. A total of 15 (30%) patients reported side-effects but only one patient was withdrawn from the treatment for this reason. No abnormality in the laboratory evaluation was observed. It is concluded that 5-HTP is effective in improving the symptoms of primary fibromyalgia syndrome and that it maintains its efficacy throughout the 90-day period of treatment.
