Botulinum toxin (BTx) has been administered for many years in the treatment of dystonias with great success. Its effectiveness is comparable with the best drugs. It was observed during spasmodic torticollis treatment that pain disappears as first before clinical improvement of dystonia. Different mechanisms of influence of BTx on pain are discussed. BTx was tried in tension headache, cluster headache, migraine, fibromyositis, painful cramps with varying results. It is possible that BTx will be useful in many other types of pain.

Working daily for a long time with a standard microscope causes back pain, fibromyalgia, or tension headache in up to 80% of microscopists. These complaints may be prevented by an ergonomic design of the microscope workstation, leading to a beneficial and significant reduction of electromyographical activity in the most strained muscle groups as shown by surface electromyographic recordings.

The aim of this paper is to review available data and current hypotheses concerning myofascial pain syndrome pathophysiology and implications for clinical practice. A muscular hypothesis has been proposed for episodic and chronic tension headache as well as for myofascial syndrome and fibromyalgia. These different syndromes may be compared as, besides their frequent combination, they have common features characterized by spontaneous pain, painful points, and lack of objective findings. They must be distinguished because each has its own diagnostic criteria. Pressure algometry appears to be a reliable method for assessing pressure sensitivity in myofascial pain. Pressure pain is not specific to tension headache and can be observed in other chronic headaches. It has not been demonstrated that the trigger points of fibromyalgia are specific in idiopathic cases. It is difficult to find an electrophysiological investigation which is specific for myofascial pain. For daily practice, the clinical approach with interview and examination remain the advisable attitude. Pathophysiological hypotheses help in better understanding of referred pain by sensitization of nociceptive central pathways according to the Ruch convergence projection theory (1965), modified by Mense in 1994. These theories do not however provide an explanation of the primary muscular mechanisms. Implications for myofascial pain patient management is discussed.

Fibromyalgia syndrome is characterized by widespread musculoskeletal pain, fatigue, poor sleep, and tenderness on palpation at multiple sites called tender points. It occurs mostly among women; only about 10% of patients are men. Two recent studies showed that women had significantly more common fatigue, morning fatigue, "hurt all over," a greater total number of symptoms, as well as a greater number of tender points. Gender differences have also been reported in other related syndromes such as tension headache, migraine, irritable bowel syndrome, chronic fatigue syndrome, and temporomandibular disorder. Although the mechanisms of gender differences in these illnesses are not fully understood, they are likely to involve an interaction between biology, psychology, and sociocultural factors.

This article is based on a vast clinical experience from patients presenting with widespread pain syndromes as well as dysfunctional symptoms from inner organs. A literature survey has been performed. Allodynia and hyperalgesia that partly explain the fibromyalgia and local myalgia syndromes seem to arise from a pathophysiological process of nociceptive sensitisation. It is proposed that the concept of "sensory sensitisation dysfunctional disorders" be applied to conditions like bronchial hyperreactivity, Da Costas syndrome, Dercum's disease (Adipositas dolorosa), dry eyes and mouth syndrome, fibromyalgia, gastralgia, globus hystericus, interstitial cystitis, chronic prostatitis, irritable bowel syndrome, photo- and phonosensitivity, rhinitis, tension headache, tinnitus, vestibulitis syndrome. These dysfunctional disorders cannot be satisfactorily explained by presently known pathophysiological models like ongoing inflammatory process, tissue degeneration, fibrosis, blood vessel diseases, tumours, immune reactions, toxic or deficiency conditions, metabolic disturbances. Neurogenic mechanisms also seem to play an important role in the pathophysiology of arthritic conditions, and might be worthwhile to include in forthcoming discussions concerning the aetiology of chronic inflammatory disease.

A significant number of pain syndromes to be found in all medical specialties, including pain therapy, can be ascribed to a group that according to the classification of the International Association for the Study of Pain (IASP) is referred to as "pain syndromes with dysfunctional etiology," or according to internal medical terminology as "functional somatic syndromes" (functional disorders), or based on psychiatric nomenclature as "somatoform disorders." Frequent syndromes exhibiting pain as the major symptom include fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), chronic pelvic pain (CPP), tension headache, chronic myoarthropathies of the masticatory system (MAP), and prostatodynia. It is important for practitioners of both somatic and psychosocial medicine to be aware of the terminology used in other fields and the frequency of comorbidities of the individual syndromes. To improve communication between somatic and psychosocial medicine as well as with patients, the authors recommend that pain therapists base their diagnosis on the ICD-10 classification and refrain from using a separate pain therapy nomenclature.

Currently it is unclear whether functional somatic syndromes can be explained by one common underlying functional syndrome. In any case it does not seem justified to view functional somatic syndromes as purely psychological disorders (somatized anxiety or depression). Psychiatric comorbidity and life time stress including traumatisations are mainly, but not exclusively responsible for triggering health care utilisation. The lowered pain threshold that can be demonstrated clinically and experimentally in fibromyalgia, irritable bowel syndrome, tension headache and temporomandibular disorders is currently seen primarily as result of an altered central nervous processing of nociceptive input. In addition some results also hint at a disturbance in the hypothalamus-pituitary-adrenal axis. The predominance of female patients can be due to gender specific illness behaviour as well as to estrogen-induced changes in pain sensitivity. In sum, functional somatic syndromes currently are best explained by a biopsychosocial model of predisposing, triggering and maintaining factors. More research is needed particularly to clarify the role of genetic and of cultural factors.

Fibromyalgia is one of a number of overlapping "functional somatic syndromes", including irritable bowel syndrome, tension headache, chronic idiopathic lower back pain, chronic fatigue syndrome and others. These conditions affect females more frequently than males and probably share common underlying neurobiological mechanisms, as well as frequent psychological, cognitive and behavioral comorbidities. Since the pain in these conditions is most likely "central" in origin, classes of drugs such as nonsteroidal antiinflammatory drugs (NSAIDs) and opioids, which are quite effective for "peripheral" pain, are relatively ineffective for the pain seen in these syndromes. Instead, tricyclic and other classes of antidepressants, antiseizure drugs and a number of other neuroactive compounds seem to be more effective. In addition, nonpharmacological therapies such as aerobic exercise and cognitive behavioral therapy are quite effective and frequently underutilized in clinical practice.

The objectives of the present study were to evaluate the presence of antipolymer antibody (APA) seropositivity in 285 Italian patients affected by primary fibromyalgia (FM) and to verify whether APA levels correlate with disease severity and with cytokine levels.APA levels were determined on serum samples by an indirect ELISA kit that detects IgG APA. Cytokines (IL-1, IL-6, IL-8, IL-10 and TNFalpha) were measured by ELISA in plasma. The impact of FM on the quality of life was estimated using the Fibromyalgia Impact Questionnaire, while pain severity was evaluated using a visual analogic scale. Patients were also characterized by the presence of tiredness, stiffness, nonrestorative sleep, anxiety, depression, tension headache, irritable bowel syndrome, temporomandibular dysfunction and Raynaud's phenomena. Using a cut-off value of 30 U, APA-positive values were detected in 60 FM patients (21.05%) and in 15 healthy control individuals (15.00%) without significant differences among their levels or the percentage of seropositivity. FM patients with moderate and severe symptoms had slightly higher APA levels with respect to patients with mild symptoms. APA-seropositive patients exhibited significant correlations between APA levels and the Fibromyalgia Impact Questionnaire estimate (P = 0.042), tiredness (P = 0.003) and IL-1 levels (P = 0.0072). In conclusion, APA cannot be considered a marker of disease in Italian FM patients. The presence of APA, however, might permit the identification of a subset of FM patients with more severe symptoms and of patients who may respond differently to different therapeutic strategies.

Acupuncture is increasingly used as an alternative or complementary therapy for the treatment of pain. It is well tolerated, with a low risk of serious adverse effects. Traditional and modern acupuncture techniques may result in reported improvement in pain patterns. Research on acupuncture has had a number of limitations, including: incomplete understanding of the physiologic effects of acupuncture; ineffective blinding of participants; unclear adequacy of acupuncture "dose;" difficulty in identification of suitable sham or placebo treatments; and the use of standardized treatment regimens rather than the individualized approach that characterizes most acupuncture practice. Controlled trials have been published regarding acupuncture for lumbar, shoulder, and neck pain; headache; arthritis; fibromyalgia; temporomandibular joint pain; and other pain syndromes. Enough data are available for some conditions to allow systematic evaluations or meta-analyses. Based on published evidence, acupuncture is most likely to benefit patients with low back pain, neck pain, chronic idiopathic or tension headache, migraine, and knee osteoarthritis. Promising but less definitive data exist for shoulder pain, fibromyalgia, temporomandibular joint pain, and postoperative pain. Acupuncture has not been proven to improve pain from rheumatoid arthritis. For other pain conditions, there is not enough evidence to draw conclusions.
