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 a fairly common syndrome characterized by chronic, widespread musculoskeletal pain, multiple "tender points", fatigue, sleep disturbance, stiffness and other symptoms such as headache, dizziness, trouble with concentration, irritable bowel syndrome, urinary urgency, depression. Fibromyalgia may occur at any age, even in childhood, is much more common in women than in men. The cause of fibromyalgia is unknown. It is difficult to diagnose because many of the symptoms are similar to symptoms of other disorders. There are no laboratory tests that can confirm a diagnosis of fibromyalgia. Average time from onset to diagnosis is 5-8 years. Treatment of fibromyalgia requires a comprehensive approach.

Intimate partner violence is currently a public health issue of great relevance. The aim of this article is to present through a literature review, the physical and psychological health problems that, beyond physical injuries, can alert health care professionals of the presence of spouse abuse in their care centers. Literature consistently shows that victims of the so called domestic violence present, compared with no victims, more chronic health problems like fibromyalgia, gastrointestinal disorders like irritable bowel syndrome, and gynaecological signs including sexually transmitted diseases, as well as post-traumatic stress disorder, anxiety and depression among others. The broad range of pathologies associated with the abuse of a sexual intimate suggests that victims will attend different health care services. These could play a key role to help these women and refer them to the appropriate legal, social and/or community services.

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.

Patients with fibromyalgia (FM) frequently have gastrointestinal symptoms and signs. This article critically reviews the available literature and concludes the following: evidence that inflammatory bowel disease is associated with FM is contradictory, but should be looked for in patients taking concomitant steroids; patients diagnosed with celiac disease often have a history of FM or irritable bowel syndrome (IBS) that may or may not be present; reflux, nonulcer dyspepsia, and noncardiac chest pain are common in FM patients; medications used to manage pain, inflammation, and gastrointestinal complaints confound the management of FM; and IBS affects smooth muscles and the parasympathetic nervous system, while FM patients have complaints of striated muscles and dysfunction of the sympathetic nervous system. Of those patients with FM, 30% to 70% have concurrent IBS. Small intestinal bacterial overgrowth is associated with hyperalgesia and IBS-like complaints, is common in FM, and responds transiently to antimicrobial therapy.

The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery, it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS, the 5-HT3 receptor has been localized in the area postrema, nucleus tractus solitarii, nucleus vaudatus, nucleus accumbens, amygdala, hippocampus, entorhinal, frontal, cingulate cortex, and in the dorsal horn ganglia. Further extraneuronal locations include among others lymphocytes, monocytes, and foetal tissue. 5-HT3 receptors modulate the release of neurotransmitters and neuropeptides like dopamine, cholecystokinin, acetylcholine, GABA, substance P, and serotonin itself. They have been demonstrated to be involved in sensory transmission, regulation of autonomic functions, integration of the vomiting reflex, pain processing and control of anxiety. While the physiologic functions of the 5-HT3 receptor are discrete and difficult to detect, it plays a key role in certain pathologic situations related to increased serotonin release. Clinical development of 5-HT3 receptor antagonists revealed a remarkable range of activities. 5-HT3 receptor antagonists do not modify any aspect of normal behaviour in animals or induce pronounced changes of physiological functions in healthy subjects. Clinical efficacy was shown for various forms of emesis like chemotherapy-induced, radiotherapy-induced, and postoperative emesis, diarrhoea-predominant irritable bowel syndrome, anxiety, chronic fatigue syndrome, alcohol abuse, and in pain syndromes such as fibromyalgia and migraine. Most recent data also suggest that 5-HT3 receptor antagonists are effective for the treatment of other rheumatic diseases such as rheumatoid arthritis, tendinopathies, periarthropathies, and myofascial pain. Other possible indications under discussion are chronic heart pain and bulimia. Unfortunately, experimental findings do not yet provide a homogenous conception of the significance of 5-HT3 receptors in all investigated fields; in nociception, for example, contradictory observations are still inadequately explained and complicated by bell-shaped dose-response curves. Further elucidation and better understanding of the serotonergic neuronal network remains a task for the next decade.

Several 5-HT3 receptor antagonists are available (tropisetron, ondansetron, granisetron, dolasetron, and palonsetron), and further compounds are in clinical development. These substances show only minor differences in the activity profile regarding their affinity for particular receptors. 5-HT3 receptor antagonists are primarily used and found effective in the prevention and treatment of chemotherapy-induced nausea and emesis, and in postoperative nausea and vomiting (PONV). Antagonism of the 5-HT3 receptors in the peripheral and central nervous system is a probable mechanism of action. The substances are suitable as first-line therapy (combined with a corticosteroid) for the prevention of acute nausea and vomiting in patients treated with moderately to severely emetogenic chemotherapeutic agents. This combination is also moderately effective in the prevention of delayed nausea and vomiting. 5-HT3 receptor antagonists are an important constituent in the prevention and treatment of emesis and nausea caused by radiation therapy, especially in patients receiving whole body or upper abdominal treatment. Alosetron was found clinically effective in diarrhoea-predominant irritable bowel syndrome, whereas tropisetron in fibromyalgia and related pain disorders. Further indications for such treatment include anxiety disorders, alcohol dependence, drug withdrawal, and psychosis related to treatment of Parkinson's disease. 5-HT3 receptor antagonists are well tolerated with the most frequently reported adverse effects being headache, constipation, dizziness, tiredness, and gastrointestinal disturbances such as abdominal pain or constipation. Intravenous administration of serotonin induces the Bezold-Jarisch reflex and causes small reversible changes in electrocardiogram (ECG) parameters.

A young woman presented with multiple central hypersensitivity disorders, including fibromyalgia, headache, pelvic pain and several smooth muscle spasm disorders, including irritable bowel syndrome, irritable bladder and Raynaud's phenomenon. She also had significant fatigue and sleep problems. Her case illustrates the importance and surprising frequency of atypical bipolar mood disorders in people with multiple central hypersensitivity pain disorders, especially with depression and anxiety resistant to antidepressant treatment. Considering neurological mechanisms common to her overlapping disorders was very helpful in guiding treatment choices. This experience illustrates the value of serotonin receptor type 2 (5HT2) inhibition with atypical neuroleptics, of neural cation channel and glutamate inhibition with anticonvulsants, and the potential usefulness of antidepressants after establishing 5HT2 control to enhance downward inhibitory tracts. Medications with combined usefulness for both bipolar mood and pain disorders were highly effective for her multiple hypersensitivity problems.

Recent evidence suggests that fibromyalgia, a chronic widespread pain condition and related syndromes (chronic fatigue syndrome, irritable bowel syndrome, etc.) may share heritable pathophysiologic features. We review the recent literature on genetic and familial factors found to participate in the pathogenesis of these syndromes, specifically fibromyalgia, including evidence suggesting that serotonin- and dopamine-related genes may play a role in the pathogenesis of these illnesses. The importance of environmental factors triggering these conditions in predisposed individuals is also discussed.
