Some chronic diseases have a favourable course and are cured spontaneously. Allergic diseases such as eczema, hay fever and asthma have a good outcome in more than 75% of cases within 7 to 25 years, depending on the kind of allergy. Migraines have also a good evolution in children and after menopause. Many symptoms due to menstruation such as dysmenorrhea, premenstrual syndrome or anemia, disappear after menopause as well as diseases due to estrogens such as uterine leiomyoma, endometriosis and prolactinoma. The risk of epilepsy relapse after a first seizure is about 40% after 2 years. The risk is lower in children. Attention deficit disorder affects 3 to 5% of children but is present in only 30% of them in adult age. The prevalence of depression decreases in women between 30 and 60 years of age. Functional somatic syndromes such as fibromyalgia, irritable bowel syndrome or dyspepsia decrease in 2/3 of cases within 5 to 10 years if there is no history of anxio-depressive symptoms. However, prognosis is reserved when initial symptoms are severe or if they are connected to sexual abuse, domestic violence or depression. Other diseases have a spontaneous favourable course such as myopia, idiopathic infertility, polycystic ovary disease or ventricular arrhythmia. The knowledge of a good prognosis enables to avoid unnecessary treatments and to reassure many patients.

Somatization disorder (SD) is commonly seen in medical clinics and is associated with significant impairment in functioning as well as excessive utilization of health care. While antidepressants have been studied in some functional somatic syndromes such as fibromyalgia and chronic fatigue, there are no pharmacologic treatment studies of SD itself. In this prospective, 8-week, open-label study, 15 patients diagnosed with either full SD or abridged somatization, by Escobar's criteria (four unexplained physical symptoms for men or six for women), were given nefazodone, titrated to 150 mg bid. The primary outcomes included measures of physical symptom severity (visual analogue scale), functioning (SF-36), and overall improvement (CGI). Fourteen of the 15 patients achieved the target dose of 300 mg/day and completed the trial. 73% of the patients were rated as improved on the CGI, 79% improved on the self-rated visual analogue scale and 73% of the patients improved on the SF-36. There was significant improvement for the whole group (prepost) on the SF-36, as well as on the HAM-D and the HAM-A. Of the nine patients with a categorical depression diagnosis, 55% of them were rated as improved on the CGI, and 67% improved on both the VAS and the SF-36. Of the six nondepressed patients, 67% were rated as improved on the CGI, 83% improved on the SF-36, and 50% improved on the VAS. Adverse events were generally mild and resulted in only one discontinuation. Although these data need to be confirmed in a larger, double-blind, placebo-controlled trial, they suggest that patients with SD will accept and tolerate therapy with nefazodone and that nefazodone may be a useful treatment for these patients.

The purpose of this study was to examine the effectiveness of low power laser (LPL) and low-dose amitriptyline therapy and to investigate effects of these therapy modalities on clinical symptoms and quality of life (QOL) in patients with fibromyalgia (FM). Seventy-five patients with FM were randomly allocated to active gallium-arsenide (Ga-As) laser (25 patients), placebo laser (25 patients), and amitriptyline therapy (25 patients). All groups were evaluated for the improvement in pain, number of tender points, skin fold tenderness, morning stiffness, sleep disturbance, muscular spasm, and fatigue. Depression was evaluated by a psychiatrist according to the Hamilton Depression Rate Scale and DSM IV criteria. Quality of life of the FM patients was assessed according to the Fibromyalgia Impact Questionnaire (FIQ). In the laser group, patients were treated for 3 min at each tender point daily for 2 weeks, except weekends, at each point with approximately 2 J/cm(2) using a Ga-As laser. The same unit was used for the placebo treatment, for which no laser beam was emitted. Patients in the amitriptyline group took 10 mg daily at bedtime throughout the 8 weeks. Significant improvements were indicated in all clinical parameters in the laser group (P = 0.001) and significant improvements were indicated in all clinical parameters except fatigue in the amitriptyline group (P = 0.000), whereas significant improvements were indicated in pain (P = 0.000), tender point number (P = 0.001), muscle spasm (P = 0.000), morning stiffness (P = 0.002), and FIQ score (P = 0.042) in the placebo group. A significant difference was observed in clinical parameters such as pain intensity (P = 0.000) and fatigue (P = 0.000) in favor of the laser group over the other groups, and a significant difference was observed in morning stiffness (P = 0.001), FIQ (P = 0.003), and depression score (P = 0.000) after therapy. A significant difference was observed in morning stiffness (P = 0.001), FIQ (P = 0.003), and depression (P = 0.000) in the amitriptyline group compared to the placebo group after therapy. Additionally, a significant difference was observed in depression score (P = 0.000) in the amitriptyline group in comparison to the laser group after therapy. Our study suggests that both amitriptyline and laser therapies are effective on clinical symptoms and QOL in fibromyalgia and that Ga-As laser therapy is a safe and effective treatment in cases with FM. Additionally, the present study suggests that the Ga-As laser therapy can be used as a monotherapy or as a supplementary treatment to other therapeutic procedures in FM.

The aim of this paper is to assess whether patient-centred consultations are more effective than the usual style of consultations used by general practitioners with patients suffering from benign chronic musculoskeletal pain and fibromyalgia. It also seeks to evaluate the differential characteristics of these two clinical groups of symptoms. The study was designed as a cluster randomised and simple blind trial. Twenty general practitioners took part and 110 patients were recruited. Compared with patients who received the usual treatment from their family physician, those who received a patient-centred approach showed greater improvement after 1 year in terms of psychological distress (anxiety) and number of tender points, as well as showing positive trends in some important outcomes such as pain intensity. Significantly better results were observed in those patients suffering chronic pain than in those with fibromyalgia, particularly as regards associated symptoms, self-rated pain and physical mobility as measured by the Nottingham health profile.

The masticatory muscles show morphologic, histochemical, electrophysical, and functional features that differ from the other muscles of the body. At least two kinds of masticatory muscle pain should be distinguished: A local pain associated with peripheral mechanical overuse, and a pain associated with changes in the central nociceptive system. Biomechanical factors appear to be important for the first type of muscle pain. Since the typical reaction of a painful muscle consists of inhibition of its activity, traditional concepts that postulate the maintenance of the pain by chronic overuse of the whole muscle are not supported by the current literature. Instead, differential overuse of discrete intramuscular regions appear to provide a more plausible explanation. On the other hand, the possible relationships between functional and structural neuroplastic changes and the second form of chronic muscle pain (e.g., fibromyalgia) still remain speculative.

We have previously shown that fibromyalgia (FMS) patients have enhanced temporal summation (windup) and prolonged decay of heat-induced second pain in comparison to control subjects, consistent with central sensitization. It has been hypothesized that sensory abnormalities of FMS patients are related to deficient pain modulatory mechanisms. Therefore, we conducted several analyses to further characterize enhanced windup in FMS patients and to determine whether it can be centrally modulated by placebo, naloxone, or fentanyl. Pre-drug baseline ratings of FMS and normal control (NC) groups were compared with determine whether FMS had higher pain sensitivity in response to several types of thermal tests used to predominantly activate A-delta heat, C heat, or cold nociceptors. Our results confirmed and extended our earlier study in showing that FMS patients had larger magnitudes of heat tap as well as cold tap-induced windup when compared with age- and sex-matched NC subjects. The groups differed less in their ratings of sensory tests that rely predominantly on A-delta-nociceptive afferent input. Heat and cold-induced windup were attenuated by saline placebo injections and by fentanyl (0.75 and 1.5 microg/kg). However, naloxone injection had the same magnitudes of effect on first or second pain as that produced by placebo injection. Hypoalgesic effects of saline placebo and fentanyl on windup were at least as large in FMS as compared to NC subjects and therefore do not support the hypothesis that pain modulatory mechanisms are deficient in FMS. To the extent that temporal summation of second pain (windup) contributes to processes underlying hyperalgesia and persistent pain states, these results indirectly suggest that these processes can be centrally modulated in FMS patients by endogenous and exogenous analgesic manipulations.

Drugs that inhibit reuptake of monoamines are frequently used to treat pain syndromes, e.g. neuropathy or fibromyalgia, where mechanical allodynia is present. Several lines of evidence suggest the involvement of supraspinal sites of action of these drugs. However, a direct study of supraspinal serotonin (5-HT) or norepinephrine (NE) release in an animal model in which allodynia is expressed, e.g. neuropathy, has not been done. The ventrobasal (VB) thalamus and the hypothalamus are major supraspinal projection regions for spinal neurons that transmit nociceptive information and are innervated by monoaminergic fibers. This study determined if peripheral neuropathy would induce changes in extracellular monoamines in VB thalamus and hypothalamus. Male Sprague-Dawley rats had spinal nerve roots L5 and L6 tightly ligated (neuropathic rats; NP) or sham (SHAM) surgery; contralateral and ipsilateral VB thalamus and contralateral hypothalamus were dialyzed with modified artificial cerebral spinal fluid (aCSF), with and without fluoxetine. NP rats had significantly decreased 5-HT content in dialysates of the contralateral VB thalamus compared with SHAM rats with (82% decrease) or without (63% decrease) fluoxetine in the perfusion medium over the 180 min of the study. There were no differences in the ipsilateral VB thalamus. In contrast, release of 5-HT was unchanged in the hypothalamic dialysates of SHAM vs. NP rats. NE release was not different in dialysates of either the VB thalamus or hypothalamus of SHAM vs. NP rats. Synthesis of 5-HT, as assessed by accumulation of 5-hydroxytrytophan after treatment with an L-amino acid decarboxylase inhibitor, was not different between NP and SHAM rats in VB thalamic and hypothalamic brain tissue. This study is the first to demonstrate changes in monoamine release supraspinally in NP rats. The differential effect between VB thalamus and hypothalamus suggests that a terminal field change may be involved. Putative mechanisms for mediating this change include alterations of GABA-ergic systems and/or plasticity related to alterations in N-methyl-D-aspartate receptor activation and nitric oxide release related to afferent hyperactivity induced by neuropathic pain.

Pain is associated with myriad medical conditions and affects millions of Americans. Chronic pain is one of the most common reasons prompting visits to healthcare providers; collectively, it possibly disables more people annually than heart disease and cancer combined. Primary goals of treating patients with chronic pain are to reduce pain as much as possible and facilitate functional restoration. When chronic pain becomes a disease state, it can be controlled, but, at present, it cannot be cured. Better understanding of the pathophysiology of acute and chronic pain has led to numerous advances in pharmacologic management of painful disorders, including low back pain, migraine headache, fibromyalgia, postherpetic neuralgia, osteoarthritis, rheumatoid arthritis, and cancer-related neuropathic pain. This presentation reviews the available agents and how to use them rationally, either singly or in combination, so practitioners can treat patients with chronic pain as effectively as possible.

Chronic fatigue syndrome (CFS) and fibromyalgia syndrome (FMS) are characterised by a lack of consistent laboratory and clinical abnormalities. Although they are distinguishable as separate syndromes based on established criteria, a great number of patients are diagnosed with both. In studies using polymerase chain reaction methods, mycoplasma blood infection has been detected in about 50% of patients with CFS and/or FMS, including patients with Gulf War illnesses and symptoms that overlap with one or both syndromes. Such infection is detected in only about 10% of healthy individuals, significantly less than in patients. Most patients with CFS/FMS who have mycoplasma infection appear to recover and reach their pre-illness state after long-term antibiotic therapy with doxycycline, and the infection can not be detected after recovery. By means of causation and therapy, mycoplasma blood infection may permit a further subclassification of CFS and FMS. It is not clear whether mycoplasmas are associated with CFS/FMS as causal agents, cofactors, or opportunistic infections in patients with immune disturbances. Whether mycoplasma infection can be detected in about 50% of all patient populations with CFS and/or FMS is yet to be determined.

Fibromyalgia syndrome (FMS) is a disorder with musculoskeletal pain as well as many other psychological and physical symptoms. Up-to-date treatment strategies for this disorder often have only limited effects. In order to develop more effective and adequate treatment tools, a phenomenological-hermeneutic study inspired by Paul Ricoeur was used. FMS patients viewed themselves on videotapes. After the video sessions the FMS patients were interviewed about thoughts that were triggered when they saw themselves on videotape. Video interpretation in combination with interviews facilitated a communication and understanding between the patient and therapist about the patients' body and self-image. The results showed that with the help of video interpretation, the patients' body and self-awareness could be improved, which in turn may help therapists to find better treatment tools for a more directed and individually adapted treatment. This is of importance as this method can be useful to FMS patients for early identification of maladaptive movement patterns and for a better integration their body and self-image. By allowing the FMS patients to interpret themselves from videotape, the FMS patients become more aware of both body and self-signals, which make it easier for the clinician/therapist to know where to start to work with each patients' specific rehabilitation programme.
