The CSF levels of Met-enkephalin-Arg6-Phe7 and dynorphin A were measured in patients with fibromyalgia. The mean CSF Met-enkephalin-Arg6-Phe7 level was 35.1 +/- 2.4 fmol/ml (mean +/- S.E.M.). The mean CSF level of dynorphin A was 14.3 +/- 0.9 fmol/ml. Regression analysis showed a statistically significant correlation between Met-enkephalin-Arg6-Phe7 and dynorphin A (r = 0.5369, P = 0.001). When correlated to the previously measured CSF levels of beta-endorphin, a statistically significant correlation was found with Met-enkephalin-Arg6-Phe7 (r = 0.5055, P = 0.03) but not with dynorphin A (P greater than 0.05). The Met-enkephalin-Arg6-Phe7 and dynorphin A levels are elevated compared to the levels available for comparison groups. Therefore, a lack of endorphin secretion does not seem to be the basis for the hyperalgesia observed in these patients.

The occurrence and characteristics of alpha-like activity during non-REM (NREM) sleep were examined in 11 subjects suffering from non-inflammatory (non-rheumatoid) musculoskeletal pain--fibromyalgia ('fibrositis'), and in 15 symptom-free controls. Both groups claimed to be good sleepers. Mean percentage alpha-like activity in sleep stages 2, 3, 4 and for NREM as a whole were greatest for the fibromyalgia group, but not significantly different from those of the controls. Overlap in the distribution of NREM alpha-like activity in sleep between the two groups indicated that it is not directly related to musculoskeletal symptoms. Spectral analyses showed a frontal area prevalence of this (kappa?) activity in the fibromyalgia group.

In the last 30 years antidepressant drugs have been used increasingly in the treatment of patients with chronic pain. This article reviews the results of some 40 placebo-controlled studies. It is difficult to make comparisons between the various studies because they often differ in terms of pain conditions, patient selection, antidepressant drug used, dosages, trial design, etc. However, in spite of this heterogeneity and other methodological problems it is clear that a wide range of pain conditions are responsive to antidepressant drug treatment, in particular: headache, migraine, facial pain, neurogenic pain, fibrositis, and probably arthritis and rheumatoid arthritis. More data need to be gathered in cancer pain, and in other conditions such as low back pain for which no, or very limited, effect has been shown. The beneficial effects of antidepressant drugs is in most cases of a mild to moderate degree, some time lag is necessary before it is completely manifest, and it tends to persist over time if drug treatment is continued in the long term. Strong evidence of efficacy is not evident for all the antidepressants, and there are probably significant differences in this respect between various drugs. The effect of a drug on pain does not seem necessarily to be related to its effect on mood. Further studies are needed to clarify this topic, and it will be necessary to examine specific pain conditions, compare different antidepressants, with reference to each other and to placebo, further investigate the role of drug plasma concentrations and control for the presence of concomitant psychiatric disturbances and for organic lesions responsible for the pain symptomatology.

Fibromyalgia, also known as fibrositis and muscle rheumatism, is a common, noninflammatory, painful musculoskeletal disorder. It is common between the ages of 30 and 60 years and has a female to male ratio of 5 to 1. Essential symptoms of fibrositis are pain, fatigue, disturbed sleep, morning stiffness and local tenderness. Subjective swelling, paresthesia and numbness sometimes occur. Multiple host and environmental factors seem to contribute to the onset and course of fibromyalgia. Modest improvement follows treatment by antidepressive agents, physical measures and reduction in stress. In this study 60 patients with fibromyalgia were investigated and the clinical characteristics of these patients are described and compared with those in other studies.

Nonarticular pain syndromes, although not inherently crippling, can have significant impact on patients' comfort, daily activities, and job performance. These syndromes include fibromyalgia, bursitis, tendinitis, and localized myofascial pain syndromes. Although differentiating these conditions from one another may be difficult, early diagnosis and follow-up are important for determining appropriate treatment. Depending on the diagnosis, treatment may include use of nonsteroidal anti-inflammatory drugs, analgesics, or corticosteroid injections; trigger-point desensitization therapy; physical therapy; and patient education.

Orofacial pain can have an inflammatory, neurologic or musculoskeletal cause. Inflammatory diseases include dental abscess, sinusitis, temporal arteritis, sialolithiasis and infections of the parotid gland. Common neurologic diseases that cause facial pain are trigeminal neuralgia, glossopharyngeal neuralgia, paratrigeminal neuralgia and cluster headaches. Musculoskeletal causes include temporomandibular joint syndrome and myofascial pain dysfunction syndrome. A clear understanding of pertinent anatomy and an organized approach to diagnosis will facilitate the evaluation of patients with orofacial pain.

The peripheral sympathetic activity was studied in 27 patients with fibromyalgia and 29 healthy controls through simultaneous measurements of electrodermal variables and blood flow at palmar skin sites during baseline, acoustic stimulation, and cold pressor tests. Compared to the controls, the patient group showed a significantly larger overall increase in the skin electrical conductance and less vasoconstriction during acoustic stimulation and cold pressor tests. These findings imply an increased activity of cholinergic and decreased activity of adrenergic components of the peripheral sympathetic nervous system in patients with fibromyalgia.

Twenty women with primary fibromyalgia syndrome and 20 age matched healthy women were investigated. The subjects performed maximum voluntary isokinetic contractions of the right quadriceps in an isokinetic dynamometer. Maximum voluntary isometric contractions of the right quadriceps were performed with superimposed transcutaneous electrical stimulation. The examination protocol was repeated after 1 h of resting. Isokinetic and isometric muscle strength was found to be, respectively, 45% (p = 0.0001) and 44% (p = 0.0001) lower in the patient group compared to the healthy subjects. The frequency of superimposed twitches was 65% in the patient group and 15% in the control group (p = 0.003). Patients with primary fibromyalgia have a lower maximum voluntary muscle strength than expected. The increased presence of superimposed electrically elicited twitches during maximum voluntary contraction indicates submaximal force application in primary fibromyalgia syndrome.

We developed a set of preliminary response criteria for use in future clinical trials in fibromyalgia syndrome. We determined outcome measures from a previously reported clinical trial which best distinguished patients treated with effective medication from those treated with placebo or ineffective medication, using stepwise logistic regression analysis. Several combinations of outcome measures were identified and plotted in the form of receiver operating characteristic (ROC) curves. The combination of variables possessing the greatest area under the ROC curve included (1) physician global assessment score less than or equal to 4 (0 = extremely well, 10 = extremely poorly), (2) patient sleep score less than or equal to 6 (0 = sleeping extremely well, 10 = sleeping extremely poorly), and (3) tender point score less than or equal to 14 (maximum possible tender point score equalled 20). These criteria accurately distinguished those treated with effective drug from those treated with placebo when tested in an unreported therapeutic trial of cyclobenzaprine. The criteria identified 11 of 14 patients in the amitriptyline trial and 4 of 6 patients in the cyclobenzaprine trial who attained improvement measured independently. The methodology used to define these preliminary criteria may be applied to refine the criteria as additional sensitive and clinically relevant outcomes are developed.

Four children with monarthritis of the knee had no further manifestations of Lyme borreliosis, but a positive antibody titer against Borrelia burgdorferi as measured by Elisa. About 3 years after antibiotic therapy none of the children had arthritis, but one suffered from fibromyalgia and another child had still a vigorous reactivity against Borrelia burgdorferi antigens by Elisa and immunoblot. In this study 4 out of 20 children with recently recognized arthritis had Lyme arthritis which makes it a rather frequent disease. The clinical presentation could not distinguish these 4 children from 4 other children with monarthritis of the knee of unknown origin. In the absence of better diagnostic criteria, the association of monarthritis, not otherwise explained, with a positive Lyme serology seems to be sufficient evidence to establish a diagnosis of Lyme arthritis. After confirmation of the diagnosis children should be treated without delay.
