Clinical evidence for the long-term effectiveness of biofeedback related relaxation training is accumulating. The purpose of this report is to describe the population, self-regulation procedure, outcome criteria, and final outcome for patients who received Quieting Response (QR) training. Data from 340 patients who completed at least the first follow-up at 3 months is presented. Primary presenting symptoms were headaches, 72%; primary and secondary Raynaud's, 14%; hypertension, 4%; irritable colon, 4%; and miscellaneous, 6%. QR training integrated EMG and thermal feedback with deep breathing, progressive relaxation, and autogenic exercises presented on cassette tapes. Eight 1-hour weekly sessions were given, with emphasis on daily home exercises. Follow-up evaluations were at 3 months, 6 months, 1 year, and 2 years. Outcome was based on change in frequency, severity, and duration of symptoms; changes in medication; and secondary benefits. Quieting Response training was found to be most beneficial for patients with primary Raynaud's disease (18 of 23 patients, or 78% successful), classic migraines (9 of 13, or 69%), and common migraines (20 of 32, or 62%), followed by mixed headaches (79 of 131, or 60%), Raynaud's plus other symptoms (9 of 15, or 60%), and the irritable colon syndrome (7 of 13, or 54%). Less successful were patients with headaches plus other symptoms (16 of 37, or 43%), muscle contraction headaches (13 of 33, or 39%), secondary Raynaud's phenomenon (4 of 10, or 40%), and essential hypertension (5 of 15, or 33%). Speculations about the differing outcomes across symptom groups were made.

Heterocyclic antidepressants have been used successfully in the treatment of migraine, enuresis and encopresis, peptic ulcer disease, irritable bowel syndrome, chronic pain, narcolepsy, sleep apnea and attention deficit disorder. The mechanism of their therapeutic effects in these conditions is still unclear. Serotonergic, noradrenergic, anticholinergic and antihistaminic properties and rapid-eye-movement sleep suppression have been implicated.

Patients with panic disorder perceive physical symptoms which they interpret as dangerous phenomena; therefore, they normally seek help from physicians in somatic medicine and do not consult with a psychotherapist or psychiatrist. The combination of physical symptoms and catastrophic thinking induces such an intense feeling of anxiety that patients often visit an emergency unit. Thus, the prevalence of panic disorder is high among patients who seek help for heart symptoms within the setting of an emergency department (18%); in other clinical populations it may even be higher (patients with negative coronary angiography 33 to 59%, with irritable bowel syndrome 29 to 38%, with migraine headache 5 to 15%). Already in the emergency department it is possible to establish with the patient an understanding of the impact such catastrophic interpretations of basically benign physical changes have on the development of panic. This helps to avoid long-standing and expensive patient careers that have often been described in the literature. The present review includes a description of the cognitive model of the origin and the treatment of panic disorder as well as an overview of drug treatments with benzodiazepines and antidepressive drugs.

Interstitial cystitis, a sterile bladder condition, is characterized by urinary frequency, urgency, burning and suprapubic pain. Increasing evidence indicates that interstitial cystitis is a heterogeneous syndrome that reflects an immune response to a variety of triggers. More than 50% of the patients have allergies, 30% have the irritable bowel syndrome and almost 20% suffer from migraine headaches. Increased numbers of mast cells have been reported in interstitial cystitis. Mast cell activation, which is critical if these cells were to be implicated in this syndrome, has been investigated by electron microscopy, which definitively shows mast cell secretion. Recently, methylhistamine, the major metabolite of histamine, and the specific mast cell marker, tryptase, were shown to be significantly elevated in urine of interstitial cystitis patients. Bladder biopsies from 53 patients were analyzed blindly for the number and degree of activation of mast cells using 4 different stains for light microscopy, as well as electron microscopy. Controls included 16 patients with incontinence and chronic bacterial cystitis. Mast cells in controls were less than 10/mm.2 and were all nearly intact. Surprisingly, mast cells from 11 cancer patients averaged 50/mm.2 but almost all were intact. In contrast, mast cells from 26 interstitial cystitis patients averaged 40/mm.2 and more than 90% were activated to various degrees. Therefore, bladder mast cell activation is a characteristic pathological finding in at least a subset of patients with interstitial cystitis.

The pharmacology of 5-HT and the classification of 5-HT receptors have become increasingly complex. However, recent advances have produced a new nomenclature system for 5-HT receptors. 5-HT3 receptors are neuronal receptors coupled directly to cation channels. Recently, many selective 5-HT3-receptor antagonists including tropisetron, zacopride, ondansetron, granisetron, zatosetron, nazasetron, YM060 and YM114 (KAE-393) have been developed. Many actions attributable to the 5-HT3-receptor have been described in both the peripheral and central nervous systems, and clinical trials are already showing the potential use of these 5-HT3 receptor antagonists in a number of disorders of the gastrointestinal tract and central nervous system, such as nausea and vomiting induced by cancer chemotherapy, anxiety, depression, schizophrenia and migraine. In addition, endogenous 5-HT is suggested to be one of the substances that mediate stress-induced responses in gastrointestinal function, i.e., increase in fecal pellet output and diarrhea. Moreover, YM060, YM114 (KAE-393) and granisetron have been reported to inhibit restraint stress- and 5-HT-induced increases in fecal pellet output and diarrhea in rats and mice, indicating that endogenous 5-HT may mediate stress-induced changes in bowel function through the 5-HT3 receptor. Therefore, 5-HT3-receptor antagonists are new therapeutic drugs for stress-induced gastrointestinal dysfunctions like irritable bowel syndrome (IBS).

There has been tremendous interest in 5-HT3 receptor antagonists since their discovery and the subsequent identification of 5-HT3 receptors in the CNS. Based on the results of early behavioural tests with these compounds, there has been substantial interest in their potential use for the treatment of various CNS disorders. In this review, Andrew Greenshaw attempts to clarify the status of the therapeutic potential of these drugs, discussing inconsistencies in preclinical findings and identifying areas in need of clarification through future research. 5-HT3 receptor antagonists are claimed to be potentially useful in the treatment of nausea, inflammatory pain (migraine and irritable bowel syndrome), anxiety, depression, schizophrenia, dementia and drug abuse!

This study reviews 71 patients who presented between 1968 and 1988 with recurrent, self-limited episodes of nausea and vomiting separated by symptom-free intervals and were diagnosed with cyclic vomiting syndrome (CVS). The length and symptomatology of episodes tended to be stereotyped and characteristic for each patient over time. The disorder may persist from months to decades. There is a coincident relationship between CVS, migraine, and irritable bowel syndrome. The differential diagnosis includes many diseases which may mimic CVS. Management involves a responsive, collaborative doctor-patient relationship, sensitivity to stresses caused by the illness and to feelings and attitudes that may predispose to attacks, use of antiemetic agents to abort or shorten attacks, treatment of complications, and use of prophylactic agents in patients whose episodes are of sufficient frequency and severity to warrant their trial.

Patients with chronic pelvic pain attending a tertiary referral centre show certain social, developmental and psychological characteristics. Specifically, they appear to have fewer children and to report more paternal overprotection, and a trend towards low maternal care compared to normals. They also show more depression, free-floating anxiety and somatic anxiety than such populations. The levels are similar to those found in other outpatient populations presenting with migraine or irritable bowel syndrome. Hostility levels are greater than those in normal subjects. Overall the present patient population reports the same degree of childhood sexual abuse as do many other female clinic and community sample populations. Sexual abuse is unlikely to be a specific aetiological factor in the development of chronic pelvic pain though it may yet be found to be important in subsets of the population.

Syndromes characterized by chronic pain and fatigue have been described in the medical literature for centuries. Fibromyalgia is the term currently used to describe this symptom complex, and considerable research has been performed in the last decade to delineate the epidemiology, pathophysiology, and genesis of this entity. Although fibromyalgia is defined by its musculoskeletal features, it is clear that there are a large number of non-musculoskeletal symptoms, such that we now understand that there is considerable overlap with allied conditions such as the chronic fatigue syndrome, migraine and tension headaches, irritable bowel syndrome, and affective disorders. This article will review our current state of knowledge regarding fibromyalgia and these allied conditions, and present a unifying hypothesis that describes both the pathophysiology of symptoms and the genesis of these disorders.

Epidemiological studies have found significant comorbidity between panic disorder and many medical illnesses. The authors discuss the accumulating psychiatric and medical literature addressing comorbidity between panic disorder and cardiac, respiratory, gastrointestinal, and neurological illnesses. Cardiac symptoms such as chest pain and palpitations, as well as certain disorders such as mitral valve prolapse, hypertension, and cardiomyopathy, share significant comorbidity with panic disorder. Researchers have also shown significant comorbidity between panic disorder and chronic obstructive pulmonary disease, irritable bowel syndrome, and migraine headache. Pathophysiological mechanisms that may explain the association between panic disorder and comorbid medical illnesses, such as autonomic dysregulation of cardiac activity and smooth muscle tone and dynamic abnormalities of the coronary microvasculature, are discussed as well.
