The term fibromyalgia, though often used, is not justified since no fibrosis has been shown on the histological level. The aim of this article is to make a critical analysis of the semiology usually attributed to fibromyalgias, to cite the main related syndromes whose nosology is often unclear (benign myalgic encephalomyelitis, epidemic neuromyasthenia, diffuse idiopathic multifocal pain syndrome, chronic fatigue, AMP desaminase deficiency, etc.), to prefer the purely descriptive term of "persistent, diffuse myalgia with no recognized organic etiology". According to the author's experience, a psychological etiology is detectable in only 25% of the cases. Morphological or functional muscular abnormalities are sometimes found, but their significance is not well known. A real multifactorial vicious circle partly explains the physiopathological complexity.

We administered a standardized history questionnaire and performed a tender point examination on 27 patients with debilitating fatigue of at least 6 months duration, seen in a primary care practice, as well as on 20 patients with fibromyalgia. Sixteen of the 27 patients with chronic fatigue met the full criteria for the working case definition of chronic fatigue syndrome (CFS). Eight patients with chronic fatigue denied having any current persistent, diffuse musculoskeletal pain, and their tender point scores were similar to those in 10 normal control subjects. In contrast, 19 patients with chronic fatigue (70%) had persistent, diffuse musculoskeletal pain. The results of their tender point examinations were similar to those of the patients with fibromyalgia. Thus, the majority of these patients with debilitating chronic fatigue, including those who met criteria for CFS, met the historical and tender point diagnostic criteria for fibromyalgia. The presence of current musculoskeletal pain will identify those CFS patients who have fibromyalgia.

Asthenic symptoms (eg, fatigue, lassitude, weakness) are of major concern in family practice setting, yet relatively little research has addressed this issue. A retrospective chart review over a 10-year period was conducted to better characterize these symptoms in a rural family practice providing health care to 508 adult patients. Asthenic complaints were recorded at least once in the medical charts of 164 patients (32%) with a preponderance of female patients. Peak prevalence occurred in the third decade of age and during the summer months. Associated symptoms, mainly pain and dizziness, were reported in 75% of the cases. A cause or diagnosis was not identified by the practicing physician in nearly 50% of the encounters; nevertheless, most episodes resolved spontaneously. Patients could be subclassified into three categories according to the recurrence pattern of their asthenic symptoms during the study period. The largest category (64%) included patients who had a single or two episodes and was thus termed "episodic asthenia." Forty-five patients (27%) with recurrent episodes (mean 4.4, range 3 to 10) were classified as having "recurrent episodic asthenia." A third small group (14 patients, 9%) with persistent complaints over the years but no evidence of the chronic fatigue syndrome were classified as having "chronic persistent asthenia." The proposed classification may help future research of asthenic symptoms in the family practice setting.

The chronic Epstein-Barr virus syndrome is a poorly defined symptom complex characterized primarily by chronic or recurrent debilitating fatigue and various combinations of other symptoms, including sore throat, lymph node pain and tenderness, headache, myalgia, and arthralgias. Although the syndrome has received recent attention, and has been diagnosed in many patients, the chronic Epstein-Barr virus syndrome has not been defined consistently. Despite the name of the syndrome, both the diagnostic value of Epstein-Barr virus serologic tests and the proposed causal relationship between Epstein-Barr virus infection and patients who have been diagnosed with the chronic Epstein-Barr virus syndrome remain doubtful. We propose a new name for the chronic Epstein-Barr virus syndrome--the chronic fatigue syndrome--that more accurately describes this symptom complex as a syndrome of unknown cause characterized primarily by chronic fatigue. We also present a working definition for the chronic fatigue syndrome designed to improve the comparability and reproducibility of clinical research and epidemiologic studies, and to provide a rational basis for evaluating patients who have chronic fatigue of undetermined cause.

The oxytocin concentration in the cerebrospinal fluid (CSF) and plasma of pregnant women at term with and without labor pain were measured by radioimmunoassay and compared with those of non-pregnant women of matched age. The oxytocin concentrations in the CSF were 4.9 +/- 4.1 microU/ml (mean +/- S.D.) in pregnant women with labor pain, 4.1 +/- 2.4 microU/ml in those without labor pain and 4.0 +/- 2.8 microU/ml in nonpregnant women, and the oxytocin concentrations in the plasma of these subjects were 45.2 +/- 19.6, 17.1 +/- 22.2 and 7.0 +/- 5.3 microU/ml, respectively. Thus the oxytocin level in the CSF did not change appreciably even when the level in the plasma was raised in the pregnant women with labor pain. These findings suggest that oxytocin does not penetrate the blood-brain barrier, and that oxytocin in the CFS has little or no central role in parturition in women.

A case of neurosyphilis is described. The presenting symptoms were reduced vision and pain around the left eye. The examination revealed a juxtapapillary chorioretinitis and neurosyphilis with elevated total protein (0.84 g/l) and pleocytosis (250 cells X 10(6)/l) in the cerebrospinal fluid (CFS). Four months after treatment with penicillin for 10 days and prednisolone for 5 weeks, the ophthalmological signs had disappeared. There was no pleocytosis (4 cells X 10(6)/l), and the total protein content in CSF was almost normal (0.52 g/l). Treatment with 6 mill (IU) penicillin G intravenously every 6 h resulted in a concentration in serum and spinal fluid higher than the generally accepted treponemacidal level.

Continuous infusion epidural anaesthesia may reduce the risks of hypotension, high spinal block and intravenous injection associated with repeated bolus injections. However, controlling the rate of a simple infusion is difficult and infusion pumps are expensive and bulky. We describe a method for continuous infusion epidural anesthesia using a 6 ml/hr capillary infusion device (Intraflo CFS-06F Sorenson Research Co., Salt Lake City, Utah) and bupivicaine 0.25 per cent. In a study of 50 patients, 35 (70 per cent) had adequate pain relief with the infusion alone for a mean time until delivery of 5 hours (range 2 to 13 hours). A further 11 patients (22 per cent) required only one top-up for the second stage of labour after a mean pain-free time of 5.4 hours (range 1.5 to 9.7 hours). There were no maternal or foetal complications related to the technique of continuous infusion used. No block went higher than the ninth thoracic dermatome at any time.

Degree of premorbid 'action-proneness' was measured, using a self-administered questionnaire, in 35 patients suffering from chronic fatigue syndrome (CFS), all the members of 'ME'-self help groups and all those meeting CDC-criteria of CFS. The results were compared with those of 30 chronic idiopathic musculoskeletal pain patients, 34 patients with a chronic organic condition, and 34 neurotic patients without primary somatic complaints. Statistical analysis showed that CFS patients described themselves as significantly more 'action-prone' than the last two groups, and to a degree which was comparable with the chronic pain group. The results could not be explained by concomitant depression and are in accordance with anecdotal reports of premorbid hyperactive lifestyle in CFS patients. Further investigations seem worthwhile to test the hypothesis that hyperactivity might be a predisposing factor for chronic illness behaviour in CFS patients.

The justification for disordered chronobiology for fibromyalgia and chronic fatigue syndrome (CFS) is based on the following evidence: The studies on disordered sleep physiology and the symptoms of fibromyalgia and CFS; the experimental studies that draw a link between interleukin-1 (IL-1), immune-neuroendocrine-thermal systems and the sleep-wake cycle; studies and preliminary data of the inter-relationships of sleep-wakefulness, IL-1, and aspects of peripheral immune and neuroendocrine functions in healthy men and in women during differing phases of the menstrual cycle; and the observations of alterations in the immune-neuroendocrine functions of patients with fibromyalgia and CFS (Moldofsky, 1993b, d). Time series analyses of measures of the circadian pattern of the sleep-wake behavioural system, immune, neuroendocrine and temperature functions in patients with fibromyalgia and CFS should determine whether alterations of aspects of the neuro-immune-endocrine systems that accompany disordered sleep physiology result in nonrestorative sleep, pain, fatigue, cognitive and mood symptoms in patients with fibromyalgia and CFS.

This article highlights chronic pain syndrome and myofascial pain. It is part of the chapter on pain rehabilitation in the Self-Directed Medical Knowledge Program for practitioners and trainees in physical medicine and rehabilitation. This article discusses behavioral maladaptations to chronic pain which lead to global physical, psychologic, social, and vocational impairments--the chronic pain syndrome. The spectrum of myofascial pain syndromes, contributing factors, and interventions are detailed. New advances that are covered in this section include controversies in long-term use of opioids and muscle relaxants; differentiating fibromyalgia, myofascial pain syndromes, and chronic fatigue syndrome; pathophysiology of myofascial pain; and beneficial treatments.
