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.

The purpose of this study was to investigate the association among daily stressors, cognitive rumination, and fibromyalgia symptoms using time-series methodology and to determine whether autocorrelation was present in the self-report data. Twelve female fibromyalgia subjects monitored their daily level of stressors, cognitive rumination, and fibromyalgia symptoms for 30-35 days. Time-series regression analyses indicated that there was a positive association between previous-day stressors and fibromyalgia symptoms for one subject and between previous-day cognitive rumination and fibromyalgia symptoms for four subjects. For 7 out of 12 subjects autocorrelation was present, and generalized least-squares methods were used with these subjects. These results indicate that ordinary least-squares methods may often not be appropriate for within-subject designs with self-report data. These results also question the often reported stressor-physical symptom association. This study illustrates a useful methodology and analysis to investigate psychosocial-physical symptom associations.

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.

Cardiovascular functional stability was studied in 17 young men (20-year-old conscripts) with the symptoms of primary fibromyalgia (PF). They were compared to 20 medical students of the same age. The subjects underwent an orthostatic test, deep breathing test, Valsalva maneuver, and a handgrip test. They were evaluated by an autoanamnestic questionnaire on vegetative symptoms and laboratory tests on blood chemistry. The heart rate of the PF group after 8 min of active standing was 32 +/- 15 beats/min greater than at supine rest. The corresponding figure for the controls was 23 +/- 7 beats/min (p = 0.001). Twelve conscripts with PF (71%) presented sympathicotonic cardiovascular reaction on the orthostatic test (p < 0.001). Four of these sympathicotonic conscripts and two other conscripts (total 35%) had an abnormal high index of dystonic symptoms (p = 0.01). The results suggest that young men with symptoms of PF have not only cardiovascular dystonic symptoms but also increased sympathetic nervous reactivity of the cardiovascular system.

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 diagnosis of a primary fibromyalgia syndrome (PFS) which is supported mainly by clinical-anamnestic elements is, in many cases, finally established in the generalized stadium of the disease. It would be generally desirable to discover potentially endangered patients and to define "risk groups". During this study a case-by-case retrospective analysis of all available data sources (specialist's and hospital reports) has been conducted on 61 PFS-patients of a general practice. A further clarification diagnosis resulted in 75% of the cases suffering from general exhaustion. In over 50% of the examined patients diagnostic details referred to chronic lumbar and cervical spine syndromes. It is well possible that chronic cervical and lumbar spine as well as psychovegetative exhaustion syndromes predispose the generation of a PFS under consideration of a corresponding personality profile and other factors or it may even be a disease by itself. In every general practice the respective tender points of suspected patients should be examined and they should be questioned as to the basic symptoms of this disease.

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.

Clinical and laboratory test data of 77 patients with systemic lupus erythematosus (SLE) were evaluated by factor analysis. Six factors representing disease patterns were extracted: cutaneous symptoms of alopecia, malar rash, rash and photosensitivity; renal involvement; the anticoagulant syndrome of phlebitis and partial thromboplastic time inversely related to platelet count; lymphopenia; viral or fibromyalgia symptoms of headache, nervousness, joint and muscle pain; and serology of anti-DNA antibodies and complement inversely related. Application of factor analysis reveals various clinical presentations of SLE.
