The essential symptoms of fibrositis--widespread aching and pain, disturbed sleep, morning stiffness, and fatigue--are common in both rheumatic and nonrheumatic patients. But the essential sign of fibrositis--widespread local tenderness over specific anatomic sites ("tender points")--is rare in any patients except those with fibrositis. Clinical criteria for the diagnosis of fibrositis rely heavily on a high tender point count in the presence of characteristic fibrositic symptoms. Multiple tender points are uncommon in normal subjects and in those with rheumatic and nonrheumatic disorders. The tender point count thus also serves to distinguish fibrositis from other musculoskeletal diseases.

The use of tricyclic antidepressants as opposed to hypnotics in treating insomnia is reviewed. Available data indicate that TCAs alleviate sleep disturbances related to depression (often before antidepressant effects are seen) and, in selected cases, may prove effective in disturbed sleep related to sleep apnea, fibrositis, and sleep related bruxism, as well as in adults with childhood onset insomnia or a history of hyperkinesis. However, TCAs share many of the problems reported for hypnotics, as well as having some potentially serious side effects not present with benzodiazepines. The need for determination of the etiology of sleep disorders, and specific pharmacotherapy directed toward identified causes rather than the symptom of insomnia, is stressed.

A recent flurry of important studies has provided critical new information that is relevant to the contemporary understanding of the fibromyalgia syndrome. The concept that these patients represent solely a form of masked depression or a distinctive syndrome of somatization is not supported by the current facts. Rather it would appear that a characteristic peripheral nociceptive component is modulated by an interplay of complex central factors. A disruption of the neuroendocrine axis controlling growth hormone production may be the link between disturbed sleep and muscle pain, as growth hormone is produced predominantly during stage four sleep. A paradigm to link some of these newer findings is presented.

Fibrositis is often associated with sleep disturbances and with an alpha nREM abnormality on sleep electroencephalogram. We describe a case occurring during the course of a typical longstanding narcolepsy-cataplexy. Modafinil, that is an effective treatment of hypersomnia, did not alleviate the symptoms of fibrositis in the short term.

The syndrome of fibromyalgia includes an unusually large and heterogeneous number of symptoms apart from the core features of generalized pain and widespread tenderness. Widespread tenderness is the only objective criterion. There is no evidence that fibromyalgia is a disease of the muscles or a rheumatic syndrome. The experience from an Australian epidemic of fibromyalgia indicates that there is an important psychosomatic component in the pathogenesis. Probably, fibromyalgia is not a disease entity; rather, the symptoms reflect difficulties in coping with various types of environmental stress. Secondary to this, sleep disturbances, fatigue, a low level of physical activity and poor physical fitness may develop, rendering the patients susceptible to muscle pain and tenderness elicited by sleep disturbances. A vicious circle may be responsible for the chronicity of the syndrome. Identification of environmental factors and early intervention should be given a high priority.

Clinical characteristics of fibromyalgia have so far been based mainly on patients identified in rheumatologic settings. This paper offers the clinical findings in fibromyalgia based on a national health interview survey, in which 123 persons fulfilled preset criteria for widespread pain. Clinical examination could be performed on 65 subjects (53%) and included physical examination, tender point palpation by two blinded trained physicians, blood sample analysis, measurement of dynamic muscular strength and a detailed self-administered questionnaire. Significantly more subjective swelling, fatigue, headache, difficulty in stair-climbing, and poorer self-evaluated health with more tender points was found. Contrary to that which was expected, fibromyalgia subjects did not suffer from sleep disturbances, irritable bowels or morning stiffness. Our findings indicate that clinical characteristics of fibromyalgia in the general population may differ from those found in rheumatological settings.

Various research studies show that the amalgam of disordered sleep physiology, chronic fatigue, diffuse myalgia, and cognitive and behavioural symptoms constitutes a non-restorative sleep syndrome that may follow a febrile illness, as in the chronic fatigue syndrome. Where rheumatic complaints are prominent such a constellation of disturbed sleep physiology and symptoms also characterizes the fibromyalgia disorder. In contrast to the chronic fatigue syndrome, fibromyalgia is associated with a variety of initiating or perpetuating factors such as psychologically distressing events, primary sleep disorders (e.g. sleep apnoea, periodic limb movement disorder) and inflammatory rheumatic disease, as well as an acute febrile illness. The chronic fatigue syndrome and fibromyalgia have similar disordered sleep physiology, namely an alpha rhythm disturbance (7.5-11 Hz) in the electroencephalogram (EEG) within non-rapid eye movement (NREM) sleep that accompanies increased nocturnal vigilance and light, unrefreshing sleep. Aspects of cytokine and cellular immune functions are shown to be related to the sleep-wake system. The evidence suggests a reciprocal relationship of the immune and sleep-wake systems. Interference either with the immune system (e.g. by a viral agent or by cytokines such as alpha-interferon or interleukin 2) or with the sleeping-waking brain system (e.g. by sleep deprivation) has effects on the other system and will be accompanied by the symptoms of the chronic fatigue syndrome.

The relationship between headaches and sleep disturbances is complex and difficult to analyze. Both symptoms may have causal relations, or may be associated in the same patient with mutual reinforcements. We studied 25 patients presenting with morning or nocturnal headaches. Standard headache diagnosis and polysomnography were performed. After polysomnography, the diagnoses were reevaluated. The main headache entities were cluster, chronic paroxysmal hemicrania, migraine, tension, combined headache, and chronic substance abuse headache. For each group, headache, sleep data, and changes in diagnosis are discussed. The diagnosis was changed in 13 patients; the final diagnoses were periodic movements of sleep, fibromyalgia syndrome, and obstructive sleep apnea. The diagnoses of cluster headache and chronic paroxysmal hemicrania were not modified by polysomnography. The migraine and tension headache groups had a relative male preponderance, and the diagnosis was changed in approximately half of the patients. This was also observed in combined headaches. Patients who had chronic substance abuse headaches had mainly insomnia, which in some cases, was relieved by stopping medication. Data were also analyzed in terms of simple models linking headache and sleep disturbances. Such an approach allowed the identification of several modes of mutual interaction. In summary, morning or nocturnal headaches are frequent indicators of a sleep disturbance and their presence might justify polysomnography, and the use of simple clinical models may be useful for understanding the complex relationship between headache and sleep.

Several electroencephalographic (EEG) abnormalities have been observed during sleep in patients suffering from the fibromyalgia syndrome (FMS). In this study, 12 patients with fibromyalgia and 14 control subjects had two polysomnographic recordings obtained at home. Data from the second night were subjected to blinded manual scoring as well as signal processing using linked or 'step-wise clustering for pattern recognition. In this procedure, a common learning set was generated using the spectral information in three 2 min EEG samples from each of the sleep stages selected from five patients with FMS and five controls. In this way, 17 characteristic EEG classes were defined. All 2 s EEG segments from the whole night from all subjects were then assigned to one of these classes. Five of the classes (dominated by 0.5-4.5 Hz activity) were more frequent in the control group, whereas three other classes (dominated by 8-11 Hz activity) were prevalent in the patient group. This trend was consistent in all sleep stages, although most striking in non-rapid eye movement (NREM) sleep. The predominance of these classes in the patient group may correspond to the alpha-EEG sleep anomaly previously reported in subjects with FMS. More importantly, as the EEG power in the lowest frequency range (prevalent in controls) probably is a marker for restorative sleep, the findings may reflect important aspects of sleep disturbances n subjects suffering from FMS, thereby contributing to some of the daytime symptoms in these patients.

To determine and compare short- and long-term effects of aerobic exercise (AE), stress management treatment (SMT), and treatment-as-usual (TAU) in fibromyalgia, 60 patients were randomized to 14 weeks of treatment by either AE, SMT or TAU. Outcome measures at baseline, midway through treatment, at treatment completion, and at 4 year follow up included a patient made drawing of pain distribution, dolorimetry of tender points, ergometer cycle test, global subjective improvement, and VAS registrations of: pain, disturbed sleep, lack of energy, and depression. Both AE and SMT showed positive short-term effects. AE was the overall most effective treatment, despite being subject to the most sceptical patient attitude prior to the study. At follow up, there were no obvious group differences in symptom severity, which for AE seemed to be due to a considerable compliance problem.
