Central panalgesia is a syndrome which includes systemic pains of a central nature, usually classified as hysteria, fibrositis and masked depression. Exploration of the peripheral neuromuscular junctions (in the iris by pupillometry, and in veins by computerized venotest) indicates an increased monoamine receptor sensitivity. 5-HT vein sensitivity is particularly impressive (up to 1,000 times). In the vein there appears to be a decentralization supersensitivity, as it is extended to different monoamines (5-HT, dopamine, noradrenaline, tyramine). This type of supersensitivity is compatible with the theory of a deficiency of neurotransmitters at the level of the anti-nociceptive and integrated systems, with subsequent central and peripheral supersensitivity. A similar condition limited to the rostral section of the anti-nociceptive system is valid for the mechanism of idiopathic headache including migraine: central and peripheral supersensitivity to monoamines and opiates is also episodically observed in headache sufferers.

This article reviewed Definition of CFS proposed by CDC 1988. There are several issues in Definition for CFS of CDC. It is presented that other chronic clinical conditions have been satisfactorily excluded, including preexisting psychiatric diseases in (2) of major criteria. However, fibromyalgia can not be excluded from the fifth symptom of minor criteria, myalgia, and also depression from the ninth symptom. It is practically difficult to define impairment of average daily activity below 50% of the patient's premorbid activity level for a period of at least 6 months, as shown in (1) of major criteria, and it is not adapted for a first visit patient. Definition for CFS of CDC has been discussed on EBV infection, but not written on postviral fatigue syndrome and myalgic encephalomyelitis. Especially whether epidemic type of CFS is present or not was not discussed. Diagnostic criteria of CFS is necessary for clinical practice.

Chronic fatigue syndrome (CFS) is easily differentiated from various neurological organic disorders by conventional clinical examinations. The most important disease for distinguishment from CFS is fibromyalgia syndrome, in which the prominent and cardinal feature is a deprivation of stage 4 slow wave sleep. Experimentally, the sleep disturbance in controls can induce general myalgia, muscle tender points, severe fatigue and stiffness on awakening. The EEG abnormality is slow alpha wave contaminants on slow wave background, which is identical to EEG of CFS. The results clearly imply that CFS is not a hysterical or psychogenic disease, and that fibromyalgia may be a central fundamental of CFS. Fibromyalgia, however, has distinct features such as no antecedent inflammatory process and no endemics. Therefore, the syndrome has features distinct from, in addition to common features to CFS. It is also very difficult to distinguish CFS from depression. The above-mentioned features can be observed in depression. Now, study of brain blood flow or metabolism by PET or SPECT can be a possible tool for establishment of the CFS identity.

Fibromyalgia is a form of nonarticular rheumatism characterized by diffuse musculoskeletal pain. To investigate the personality characteristics of fibromyalgia, Ko's Mental Health Questionnaire was evaluated in 27 fibromyalgia patients and 23 normal controls. The fibromyalgia patients scored significantly higher than normal controls on hypochondriasis, depression, anxiety and compulsion, and significantly lower on independence. The fibromyalgia patients had 52% incidence of depression. Major depression occurred before onset of fibromyalgia at a mean of 5.5 years in 36% of the patients who experienced depression. The longer the duration of fibromyalgia, the higher the incidence of depression, and more numbers of tender points, indicating that the symptoms of fibromyalgia were more severe.

Both fibromyalgia and depression may be related to disturbed serotonin metabolism, and an association between the 2 disorders has been postulated. We measured 3H-imipramine binding (IB), a biochemical indicator of serotonin uptake, pretreatment, in 10 nondepressed women with fibromyalgia, 14 subjects with major depression, and 10 volunteer controls. Our objective was to determine if IB in the 2 patient groups differed and in the same direction from the control values. Compared with depressed women, IB was significantly lower both in the women with fibromyalgia and in the men with depression. However, no women with fibromyalgia or men with depression had IB levels that were significantly different from control women and men. There was a trend for higher IB levels in depressed compared to control women.

Previous research has demonstrated a number of conditions, such as sleep disturbance, fatigue, depression, spastic colon and mitral valve prolapse, associated with fibromyalgia. The present report describes additional symptoms and medical conditions that appear to be associated with the syndrome based on a survey of 554 individuals with fibromyalgia compared with a group of 169 controls. Individuals with fibromyalgia self report a greater incidence of bursitis, chondromalacia, constipation, diarrhea, temporomandibular joint dysfunction, vertigo, sinus and thyroid problems. Symptomatic complaints found statistically more prevalent in fibromyalgia patients included concentration problems, sensory symptoms, swollen glands and tinnitus. Other associations occurring with significant increased frequency were chronic cough, coccygeal and pelvic pain, tachycardia and weakness. Our previous report on inheritance patterns in fibromyalgia was reaffirmed with 12% reporting symptomatic children and 25% reporting symptomatic parents. Of the respondents, 70% noted that their symptoms were aggravated by noise, lights, stress, posture and weather.

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.

Lyme encephalopathy, primarily manifested by disturbances in memory, mood, and sleep, is a common late neurologic manifestation of Lyme disease. We compared 20 patients with Lyme encephalopathy with 11 fibromyalgia patients and 11 nonpsychotically depressed patients using the California Verbal Learning Test, Wechsler Memory Scale, Rey-Osterrieth Complex Figure Test, Minnesota Multiphasic Personality Inventory (MMPI), and Beck Depression Inventory. Compared with patients with fibromyalgia or depression, the Lyme encephalopathy group showed mild, but statistically significant, memory deficits on two of the three memory tests. In contrast, the patients with fibromyalgia scored significantly higher than both other groups on the MMPI scale most sensitive to somatic concerns (scale 1), while the depressed patients scored higher than the Lyme patients on the scales most sensitive to depression (scale 2) and anxiety (scale 7). Physical complaints and depression were not major factors in memory performance among Lyme patients. These data support the hypothesis that Lyme encephalopathy is caused by CNS dysfunction and cannot be explained as a psychological response to chronic illness.

Muscle pain occurs in various neuromuscular disorders with characteristic physiological or biochemical abnormalities. There is, however, a group of patients in whom there is no clear physiological or structural basis for their pains. This syndrome has been called fibrositis or fibromyalgia. Sleep abnormalities have been reported in some of these patients, but have not been confirmed by others. We studied 8 patients with this disorder and found sleep abnormalities that were characterized by nocturnal myoclonus, alpha-delta sleep, and abnormalities compatible with depression. Polysomnography was, therefore, instrumental in helping direct the treatment of these patients. Therapeutic approaches aimed to correct the specific disorders were effective in improving the pain symptoms.

An instrument has been developed to assess the current health status of women with the fibromyalgia syndrome. The Fibromyalgia Impact Questionnaire (FIQ) is a brief 10-item, self-administered instrument that measures physical functioning, work status, depression, anxiety, sleep, pain, stiffness, fatigue, and well being. We describe its development and validation. This initial assessment indicates that the FIQ has sufficient evidence of reliability and validity to warrant further testing in both research and clinical situations.
