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.

The treatment of patients with Irritable Bowel Syndrome has not been very successful because of the number of variations that are associated with the illness. Some of them are: Depression and Anxiety, intensity of the symptoms and colonic hypersensitivity, all this, added to the unknown etiology of the illness. This review expects to bring a global vision of the difficulty that has existed for Medicine or psychology to bring the best treatment to these patients. Diverse investigations had obtained successful results with different psychotherapeutic approaches (Hypnotherapy, Psychoanalysis, cognitive therapy, multicomponent therapy, etc.). Nevertheless these present methodological errors that put in doubt those results. It is thought that interdisciplinary treatment would be a good option for these patients.

All studies confirm IBS is one of the most common problems in medical practice, and the most common in gastroenterologic practice, underdiagnosed in many cases, misdiagnosed in others. In our country there are no studies published to describe the prevalence of symptoms of IBS. Our objective was to evaluate the prevalence of Manning s Criteria, in an apparently healthy population, of high socioeconomical level, from Lima. We carried-out a cross-sectional study of prevalence in 300 subjects from 5 districts of higher socioeconomical level of Lima. We found 78 persons with lower bowel symptoms (26%). The most frequent symptom-criterion in this population was mucus in stools, meanwhile the least frequent was the increase in frequency. We do not find differences between frequency of symptoms with depression associated, sex, age, nor districts. Our frequency of symptoms is not in accord with traditionally described in this syndrome.

In a population of 71 (57 female, 14 male) IBS patients seeking psychological treatment, we found expected levels of childhood sexual and physical abuse (57.7%) and expected levels of current Axis I psychiatric disorders (54.9%). Moreover, we found those who had been victims of early abuse had higher current Beck Depression Inventory scores. However, contrary to expectations, there were no significant associations between early abuse and current psychiatric disorder in this population, suggesting that those individuals with psychological distress are not exactly the same group with a history of abuse.

Abbott and Takeda are developing TAK-637, an orally active NK1 antagonist, for the potential treatment of urinary incontinence, depression, irritable bowel syndrome and pollakiuria. By November 1999, it was in phase II trials in Europe and phase I in Japan and the US for urinary incontinence [348496], [350686]. By October 2000, phase II trials had been initiated in the US for urinary incontinence, depression and IBS [381167], [386950], [419868], and in May 2001, these were scheduled to finish in 2002 [412024].

Severe fatigue is a common complaint among patients. Often, the fatigue is transient or can be attributed to a definable organic illness. Some patients present with persistent and disabling fatigue, but show no abnormalities on physical examination or screening laboratory tests. In these cases, the diagnosis of chronic fatigue syndrome (CFS) should be considered. CFS is characterized by debilitating fatigue with associated myalgias, tender lymph nodes, arthralgias, chills, feverish feelings, and postexertional malaise. Diagnosis of CFS is primarily by exclusion with no definitive laboratory test or physical findings. Medical research continues to examine the many possible etiologic agents for CFS (infectious, immunologic, neurologic, and psychiatric), but the answer remains elusive. It is known that CFS is a heterogeneous disorder possibly involving an interaction of biologic systems. Similarities with fibromyalgia exist and concomitant illnesses include irritable bowel syndrome, depression, and headaches. Therefore, treatment of CFS may be variable and should be tailored to each patient. Therapy should include exercise, diet, good sleep hygiene, antidepressants, and other medications, depending on the patient's presentation.

Functional disorders of the digestive system, such as irritable bowel syndrome, are often associated with affective disorders, such as depression, anxiety, panic, and posttraumatic stress disorder (PTSD). Some of these associations are observed not only in clinical populations, but also in population-based samples, suggesting a relationship with pathophysiologic mechanisms underlying both gastrointestinal (GI) dysfunction and certain affective disorders. Sustained and acute life-threatening stressors play an important role in the onset and modulation of GI symptoms as well as in the development of affective disorders and PTSD. A neurobiological model is proposed that attempts to explain the development of visceral hypersensitivity, the neuroendocrine and autonomic dysfunction characteristic of functional GI disorders, as well as the overlap with affective disorders.

The current study describes the successful administration of hypnotherapy with a subject suffering from refractory Irritable Bowel Syndrome (IBS) and Generalized Anxiety Disorder (GAD). The subject had suffered from IBS for 30 years and had unsuccessfully pursued multiple psychological treatments, both traditional and non-traditional. He was referred to the Center for Stress and Anxiety Disorders and commenced hypnotherapy directed primarily at the IBS symptoms. After 6 treatment sessions, his IBS symptomatology had improved 53%. He stopped treatment at that point and continued autohypnosis with the aid of treatment audiotapes provided by his therapist. Follow-up at 6 months indicated continued improvement (70%). A 2-year follow-up revealed an improvement of 38% in IBS symptomatology. Concurrent levels of depression and anxiety had also substantially decreased. Hypnotherapy is shown to be a viable, palatable, and enduring treatment option for an individual who had been refractory to many previous therapies.

Pain is perceived, transmitted, processed and modulated within an extensive network of neurotransmitters and hormones. Despite increasing knowledge about the biologic principles, even on the molecular level, the more we learn about the precise mechanisms of their interactions the more questions arise. It is also pertinent to remember that clinical scientists studying pain modulating pharmacologic agents always have to consider possible placebo effects [57-61]. Most of our knowledge regarding the function of neurotransmitter systems in the CNS has been provided by animal studies. Thus we cannot be sure that they have exactly parallel counterparts in humans. For instance, animal studies suggest an inverse relationship between brain and spinal cord concentrations of substance P. If these observations are converted to an interpretation of human fibromyalgia, low brain-tissue levels of both serotonin and substance P should be expected, while spinal cord serotonin concentrations would be low and spinal cord substance P would be high [1]. There is good evidence that 5-HT, its receptors, and their interactions with other neurotransmitters are essential for nociception and antinociception. The activities of 5-HT receptors can be studied by agonist and in humans especially by antagonist use. But even with a direct spinal application of selective agonists and antagonists, observations may still be confounded by (1) dose, as there can be a dose-dependent activation of different receptor subtypes; (2) type of nociceptive tests (e.g., thermal versus pressure versus chemical models), which may have differences in the way they are regulated; and (3) influences due to effects on temperature, blood flow or motor function. With this potential for variability, it is perhaps not surprising that there is some variability in the results of studies reporting on the effects of various 5-HT agonists and antagonists on nociceptive transmission within the spinal cord [62]. For instance, different 5-HT3 receptor densities could exist in various neuronal systems, one density type being completely inhibited at low concentrations, and the others only at higher concentrations of 5-HT3 receptor antagonists, thus resulting in contrary effects. Finally, the "endogeneous 5-HT tone" may greatly influence agonist and antagonist action. Considering this complexity of serotonin-mediated reactions, it is not surprising that treatment of pain by 5-HT3 receptor antagonists appears to yield inconsistent results. As fibromyalgia is now regarded as a pain amplification syndrome with a broad variety of additional nonpain symptoms, the interrelations are complicated even more. Fibromyalgia associated symptoms (e.g., fatigue, insomnia, and irritable bowel syndrome) can be modulated by 5-HT3 receptor antagonists. From the data evaluated so far, there is evidence that 5-HT3 receptor antagonists provide significant benefit in some fibromyalgia patients. In our practice, the data justify a careful application in clinical use according to the study results. The dosage, route of application, long term adverse reactions and duration of therapy still need to be studied in greater detail. Recently reported adverse events from therapy of irritable bowel syndrome with alosetron [63-67] provide a note for caution before hastily using 5-HT3 receptor antagonists without more studies. One can surmise that, much as the biochemistry of depression has been elucidated by the development of the SSRIs, a greater understanding of the role of 5-HT3 receptor antagonists in treating fibromyalgia patients may provide some insights into disease mechanisms of this enigmatic disorder.

The efforts of clinical researchers, lay organizations and pharmaceutical companies have increased the public profile of irritable bowel syndrome and made it a respectable diagnosis. Diagnostic symptom criteria encourage a firm clinical diagnosis, which is the foundation of a logical management strategy. This begins with education. Reassurance that no structural disease threatens should be tempered with the reality that symptoms are likely to recur over many years. Patients expect diet and lifestyle advice, even if this is not specific to irritable bowel syndrome. Only a few of those with irritable bowel syndrome see doctors, and even fewer see specialists. Therefore, the treating physician should ascertain the reason for the visit, the patient's fears and the presence of any comorbid illness, such as depression, that might require treatment in its own right. No drug treatment is useful for all of the symptoms of irritable bowel syndrome, and many patients require no drug at all. If used, drugs should target the predominant symptom. Alosetron, a 5-HT3 antagonist, is effective in treating women with irritable bowel syndrome who also have diarrhoea. Tegaserod, a 5-HT4 agonist, is useful for women with irritable bowel syndrome who are constipated. Most patients with irritable bowel syndrome need psychological support. Reassurance, discussion and relaxation techniques can be provided by the family doctor. Difficult psychopathology may require referral to a mental health professional, and the gastroenterologist can settle diagnostic uncertainties. In all cases, successful treatment depends on a confident diagnosis and the strength of the doctor-patient relationship.
