The literature on fibrositis (fibromyalgia), which originated in the early years of the last century in the UK and proliferated there in the first half of this century, has since diminished there in the last 30 years or so, but has increased in Canada and the US. Criteria suggested for diagnosis have created a syndrome with no diagnostic tests, serological or radiological signs, and no truly objective physical signs, but with predictable tender spots on pressure. The syndrome is largely, but not completely, confined to females, mostly of middle age; the symptoms include widespread aching of more than 3 months' duration, disturbed sleep, morning fatigue and stiffness, a failure to respond satisfactorily to any one form of therapy and a tendency to persist over long periods, but without permanent tissue changes. Features of psychological disturbance are present in many patients but not in all or even the majority. Definition of the condition as a disorder of pain modulation - a pain amplification syndrome - would seem to fit the facts best. Most would agree that an abnormal response to stress is an important factor in the appearance of the syndrome, as other stress related disorders, such as the irritable bowel syndrome and tension headaches, may coexist. Response to therapy, whether physical or pharmacological, is on the whole unsatisfactory. This type of patient has been well recognised in hospital clinic and general practice for many years.(ABSTRACT TRUNCATED AT 250 WORDS)

The paper by Sperber et al. in this issue is an early evaluation of the Rome III criteria against the Rome II criteria for irritable bowel syndrome that throws up several important observations. A three to four-fold increase was observed in irritable bowel syndrome prevalence with the Rome III criteria. Individuals with the Rome II criteria had more doctor visits, perception of stress and a negative global feeling. There could be a shift of individuals between irritable bowel syndrome and other functional bowel disorder diagnostic groups such as functional constipation and functional bloating. In this review, it is suggested that rigid application of the symptom frequency and duration requirements of the older Rome criteria could have introduced a selection bias for patients with greater psychological disturbance, and that this could have impacted negatively on our perception and management of irritable bowel syndrome. The findings of Sperber et al. suggest that the new Rome III criteria may enable us to pay more attention to the average irritable bowel syndrome patient we see in our clinics as opposed to the chronically severe patient. It is proposed that improved management of our average patient may translate into better outcomes in terms of reduction in specialist referral, unnecessary surgery and potentially harmful alternative treatments.

Fibromyalgia syndrome (FM) is a common chronic pain condition that affects at least 2% of the adult population. Chronic widespread pain is the defining feature of FM, but patients may also exhibit a range of other symptoms, including sleep disturbance, fatigue, irritable bowel syndrome, headaches, and mood disorders. The etiology of FM is not completely understood and the syndrome is influenced by factors such as stress, medical illness, and a variety of pain conditions. Establishing diagnosis may be difficult because of the multifaceted nature of the syndrome and overlap with other chronically painful conditions. A unifying hypothesis is that FM results from sensitization of the central nervous system; this new concept could justify the variety of characteristics of the syndrome. FM symptoms can be musculoskeletal, non-musculoskeletal, or a combination of both; and many patients will also experience a host of associated symptoms or conditions. The ACR classification criteria focus only on pain and disregard other important symptoms; but three key features, pain, fatigue and sleep disturbance, are present in virtually every patient with FM. Several other associated syndromes, including circulatory, nervous, digestive, urinary and reproductive systems are probably a part of the so called central sensitivity or sensitization syndrome. A minority subgroup of patients (30-40%) has a significant psychological disturbance. Psychological factors are an important determinant of any type of pain, and psychological comorbidity is frequent in FM. Psychiatric disorders most commonly described are mood disorders, but psychiatric illness is not a necessary factor in the etiopathogenesis of FM.

In this review we have unearthed epidemiological data that; support the 'old' concept of irritable bowel syndrome (IBS) as a disorder of civilization, build a 'new' symptom profile of IBS for Asia, and persuade us against the use of 'borrowed' Western diagnostic criteria and illness models by Asian societies. In the 1960s, IBS was described as a disorder of civilization. Early studies from Asia suggested a prevalence of IBS below 5%. Recent studies from Asia suggest a trend for the more affluent city states like Singapore and Tokyo, to have higher prevalence of 8.6% and 9.8%, respectively, while India had the lowest prevalence of 4.2%. Furthermore, there was a trend among the better educated and more affluent strata of society in several urban Chinese populations for a higher prevalence of IBS, as well as a trend for a higher consultation rate. Across Chinese and Indian predominant populations, a majority of patients with IBS criteria report upper abdominal symptoms such as epigastric pain relieved by defecation, bloating and dyspepsia. Bloating and incomplete evacuation appear to be more important determinants of consultation behavior, than psychological factors. The failure of the Rome criteria to recognize the relationship to meals, may have led to a substantial misclassification of IBS as dyspepsia. The relevance of the Western model of psychological disturbance as a determinant of consultation behavior is questionable because of the accessibility and acceptability of medical consultation for gastrointestinal complaints in many Asian communities.
