Uterine fibroids, the most common tumours in women of reproductive age, are asymptomatic in at least 50% of afflicted women. However, in other women, they cause significant morbidity and affect quality of life. Clinically, they present with a variety of symptoms: menstrual disturbances including menorrhagia, dysmenorrhoea and intermenstrual bleeding; pelvic pain unrelated to menstruation; and pressure symptoms such as a sensation of bloatedness, increased urinary frequency and bowel disturbance. In addition, they may compromise reproductive function, possibly contributing to subfertility, early pregnancy loss and later pregnancy complications such as pain, preterm labour, malpresentations, increased need for caesarean section, and postpartum haemorrhage. Large fibroids may distend the abdomen, which may be aesthetically displeasing to many women. Abnormal bleeding occurs in 30% of symptomatic women, and abnormal bleeding, bloating and pelvic discomfort due to mass effect constitute the most common symptoms. The incidence of fibroids is highest in Black women, who tend to have multiple and larger fibroids, and more symptomatic fibroids at the time of diagnosis. The prevalence of clinically significant myomas peaks in the perimenopausal years and declines after the menopause. It is not known why some fibroids are symptomatic while others are quiescent. The size, number and location of fibroids undoubtedly determine their clinical behaviour, but research has yet to correlate these parameters with clinical presentation of the fibroids.

Most women of reproductive age have some physical discomfort or dysphoria in the weeks before menstruation. Symptoms are often mild, but can be severe enough to substantially affect daily activities. About 5-8% of women thus suffer from severe premenstrual syndrome (PMS); most of these women also meet criteria for premenstrual dysphoric disorder (PMDD). Mood and behavioural symptoms, including irritability, tension, depressed mood, tearfulness, and mood swings, are the most distressing, but somatic complaints, such as breast tenderness and bloating, can also be problematic. We outline theories for the underlying causes of severe PMS, and describe two main methods of treating it: one targeting the hypothalamus-pituitary-ovary axis, and the other targeting brain serotonergic synapses. Fluctuations in gonadal hormone levels trigger the symptoms, and thus interventions that abolish ovarian cyclicity, including long-acting analogues of gonadotropin-releasing hormone (GnRH) or oestradiol (administered as patches or implants), effectively reduce the symptoms, as can some oral contraceptives. The effectiveness of serotonin reuptake inhibitors, taken throughout the cycle or during luteal phases only, is also well established.

The definition of irritable bowel syndrome (IBS) by Rome criteria was a major advancement in the nosology of the disease, but this goal was achieved by employing symptoms related to the gastrointestinal tract and by eliminating all symptoms that were nonspecific. The description of the course of the illness and response to treatment has been hampered by restrictions to the defining characteristics, abdominal pain and altered bowel habit. Other abdominal symptoms (e.g., bloating, nausea, and epigastric discomfort) and general somatic symptoms (e.g., fatigue, headache, and sleep disturbance) are not included in the Rome definition, yet are commonly reported by patients with IBS. This article addresses the following questions: Are comorbid conditions part of or distinct from the syndrome of IBS and other functional gastrointestinal disorders (FGIDs)? Are there overlapping abdominal or extra-abdominal symptoms confounding the definition of IBS? Are extra-abdominal somatic symptoms and/or syndromes part of the clinical presentation of IBS? Are "nondiagnostic" abdominal symptoms important in defining symptom burden in IBS? Is the concept of somatization related to IBS, and, if so, how? How can we better define the symptom burden in IBS and other FGIDs? In short, have we hampered the evaluation of IBS (and other FGIDs) by making the definitions too reductionist? While definite answers to the above questions are not possible at this time, this article proposes that the definitions of IBS or other FGIDs not be altered, but that in the process of evaluation of the clinical end points and/or severity of the diseases, consideration be given to the possibility of including other components of the symptom burden of these disorders.

Functional bowel disorders (FBDs) are common disorders that are characterized by various combinations of abdominal pain and/or discomfort, bloating and changes in bowel habits. At present, diagnosing FBDs often incurs considerable health-care costs, partly because unnecessary investigations are performed. Patients are currently diagnosed as having an FBD on the basis of a combination of typical symptoms, normal physical examination and the absence of alarm features indicative of an organic gastrointestinal disease. Basic laboratory investigations, such as a complete blood count, measurement of the erythrocyte sedimentation rate and serological tests for celiac disease, are useful in the initial evaluation. No further investigations are needed for most patients who have typical symptoms and no alarm symptoms. The most important alarm symptoms include signs of gastrointestinal bleeding, symptom onset above 50 years of age, a family history of colorectal cancer, documented weight loss and nocturnal symptoms. The presence of alarm symptoms obviously does not exclude an FBD, but further investigation is needed before confirmation of the diagnosis. For patients with predominant and severe diarrhea, a more thorough diagnostic work-up should normally be considered, including colonoscopy with colonic biopsies and a test for bile-acid malabsorption.

In the United States, more women than men seek health-care services for symptoms of irritable bowel syndrome (IBS). A number of explanations are given for this gender difference including the higher rates of somatic non-gastrointestinal symptoms and increased psychological distress reported by women with IBS. However, these gender differences are found in studies that rely on retrospective recall with little attention to age or reproductive status. The purpose of the current analysis was to prospectively compare the frequency (days/month of moderate to severe based on a daily diary) of somatic, gastrointestinal (GI), and psychological distress symptoms, in menstruating women (N = 89) and postmenopausal women (N = 66) to men (N = 32) with IBS. In addition, the correlation between daily symptoms and daily report of overall health was evaluated. Postmenopausal women reported significantly more GI pain/discomfort symptoms, especially bloating and abdominal distension, than men, however these differences are greatly attenuated when age is controlled for. Both postmenopausal and menstruating women reported significantly more somatic symptoms (especially joint pain and muscle pain) than men with IBS. The effect was stronger in postmenopausal women, whose somatic symptoms were also higher than menstruating women (P = 0.014). Fatigue and stress were higher in women than men but anxiety and depression were not. All three types of symptoms were strongly correlated with self-rating of health, both across and within-person. Gender-related differences in GI and somatic symptoms are apparent in persons with IBS, more strongly in postmenopausal women. The presence of somatic symptoms in postmenopausal women with IBS may challenge clinicians to find suitable therapeutic options.

Psychosomatics as a medical perspective and discipline focuses on the interaction of physical and mental health in a specific life situation of a patient, taking into account the physical and emotional wellbeing, role functioning, satisfaction with the partner and family relationship, as well as sexual function and satisfaction. The role of progesterone for the psychosomatic health of the climacteric woman depends on the individual symptom cluster and the pre-existing receptivity of the progesterone receptors which are widely distributed in the body and especially the brain of the woman. The complex action and interaction of progesterone is reflected in controversial empirical results about the impact of progesterone on the physical, mental and sexual health of climacteric women. From biological rationale and clinical experience there are however two important effects of P on the combined physical, mental and sexual wellbeing of climacteric patient: the antiestrogenic effect of progesterone is important on the peripheral physical level not only to protect the endometrium against overstimulation but also to reduce the individual suffering from heavy bleeding, breast tension, bloating and general discomfort. The positive anxiolytic and sedative effects of progesterone on the central nervous system depend on the type of progestogen, the dosage, the timing of application, the combination with estrogen etc. It can be concluded that progesterone and progestogens have an important potential to maintain or improve the psychosomatic health of the climacteric women. Their use must however be tailored to specific symptom clusters and to the individual's pre-existing psychosomatic health status.

Acute studies suggested a therapeutic benefit for fundus-relaxing drugs in functional dyspepsia (FD) with visceral hypersensitivity (VH) to gastric distention or impaired accommodation (IA), but long-term studies are lacking. R-137696 is a serotonin-1A (5-HT(1A)) receptor agonist which relaxes the proximal stomach in man. Our aim was to investigate the influence of R-137696 on symptoms in FD with VH or IA. Randomized, double-blind, placebo-controlled, parallel group study of 4 weeks R-137696 2 mg t.i.d. in FD with VH or IA. Symptoms were assessed using the patient assessment of upper gastrointestinal symptom severity index (PAGI-SYM) total score and individual symptom subscales. Barostat studies were performed before and after 4 weeks of treatment. Fifty-three patients (33 VH and 20 IA), 18 men, mean age 40 +/- 13 years were recruited. Twenty-four received placebo and 29 received R-137696. In VH patients, both placebo and R-137696 improved total symptom scores, with a tendency for superiority of placebo (-1.12 vs-0.51, P = 0.07). Placebo was superior for the subscales of early satiety, bloating, fullness and discomfort (all P < 0.05). In IA, both placebo and R-137696 had no significant influence on total or individual symptom scores (-0.08 and -0.27). In VH, both placebo and R-137696 increased the discomfort volume, without a statistical difference between both arms (+120 and +164 mL). In IA, both placebo and R-137696 enhanced accommodation, without a statistical difference between both (+77 and +159 mL). Adverse events were similar for drug and placebo. A 4-week administration of the fundus-relaxing 5-HT(1A) agonist R-137696 failed to significantly improve symptoms, VH or gastric accommodation compared to placebo.

Both dyspeptic and gastro-oesophageal reflux-like symptoms are frequent in the general population, but their degree of overlap is unknown. In severe functional dyspepsia (FD), symptoms are organized in factors associated with pathophysiological mechanisms. The aims of this study were: (i) to assess the prevalence of dyspeptic symptoms with and without overlapping reflux symptoms in the general population and their impact on daily life and on healthcare utilization; and (ii) to compare symptom groupings in the general population to FD patients. A total of 2025 subjects, representative of the Belgian general population, were used in this study. The subjects were submitted to a questionnaire with validated questions on their dyspeptic and reflux symptoms and with evaluators of impact on daily life and use of healthcare resources. Significant dyspeptic symptoms were found in 417 (20.6%). Overlapping reflux symptoms were present in 141 (33.8%). In this group, symptoms were more frequent and more severe. Dyspeptic symptoms induced weight loss (12.7%) and absenteeism (12.4%), affected daily life (61.2%) and generated use of healthcare resources, such as medical consultations (61.4%) and medication (70.9%). Factor analysis revealed a three-component structure with factor 1 including fullness, bloating and early satiety, factor 2 including nausea and vomiting and factor 3 including discomfort, pain, belching and reflux. If forced in a four-factor model, the analysis separates belching as independent factor. Dyspeptic symptoms are frequent in the general population, with overlapping reflux symptoms and increased symptom burden in about a third.

The pathophysiology of functional dyspepsia (FD) is unknown and several mechanisms associated with specific symptom patterns have been recently proposed. Increased duodenal acid exposure has been supposed to be associated with nausea, but recently an increase of severity of several dyspeptic symptoms was noted in a subset of dyspeptic patients. As its pathogenetic role is still unclear, we evaluated an involvement of duodenal acid exposure in symptom generation by inducing a hyperacidity status of the duodenum. Twelve young adult healthy volunteers in a randomized, double-blind protocol, underwent duodenal acid (0.2 N, 5 mL min(-1)) or saline perfusion, antropyloroduodenal manometry and duodenal pH monitoring both during fasting and postprandially. Every 15 min, severity of discomfort, fullness, bloating, belching, nausea, heartburn, epigastric burning, satiety and pain were evaluated by visual analogue scale. During acid perfusion, symptom scores for discomfort, bloating, nausea, epigastric burning were significantly higher (P < 0.01) compared to saline. Postprandial antral motility index was lower (2.96 +/- 1.8 vs 3.62 +/- 1.8, P = 0.01) and jejunal motility index higher (4.87 +/- 1.0 vs 4.37 +/- 1.4, P = 0.01) during acid perfusion. Occurrence and duration of phases III of the migrating motor complex showed no difference. Duodenal acid perfusion causes a sensitization to dyspeptic symptoms and induces antral hypomotility and jejunal hypercontractility. Through these mechanisms, increased duodenal acid exposure may play a role in the pathophysiology of FD symptoms.

The patient assessment of upper gastrointestinal symptom severity index (PAGI-SYM) questionnaire was recently developed and validated for the evaluation of therapeutic responsiveness in functional dyspepsia (FD). Functional dyspepsia is a heterogeneous disorder, with different pathophysiological mechanisms underlying the symptom pattern. The relationship between PAGI-SYM scores and putative pathophysiological mechanisms has not been studied. The aim of this study was to evaluate the relationship between PAGI-SYM subscales and gastric emptying, gastric sensitivity and gastric accommodation in FD. A total of 161 consecutive FD patients underwent Helicobacter pylori (HP), gastric barostat and standardized gastric emptying testing (n = 126), and completed the PAGI-SYM questionnaire. Relationships between scores for the six subscales (heartburn/regurgitation, nausea/vomiting, fullness/satiety, bloating, upper abdominal pain, lower abdominal pain) and gastric function were analysed using Pearson's linear correlation, multiple regression analysis, chi-square and Student's t-tests. Gastric emptying was significantly correlated with scores for heartburn/regurgitation (r = 0.26), nausea/vomiting (r = 0.19), fullness/satiety (r = 0.20), bloating (r = 0.21) and lower abdominal pain (r = 0.22; all P < 0.05). Patients with delayed emptying had significantly higher scores for each of these subscales (all P < 0.05). Discomfort volume during gastric distension was significantly correlated with scores for fullness/satiety (r = -0.27), bloating (r = -0.23), heartburn/regurgitation (r = -0.21), and upper abdominal pain (r = -0.20). Patients with hypersensitivity to distension had significantly higher scores for fullness/satiety (P < 0.05). At different cut-off levels of symptom severities, consistent associations were found between fullness/satiety and gastric discomfort volume, between preprandial volumes and upper abdominal pain, compliance and upper abdominal pain, and between bloating and gastric discomfort volume. Multiple regression analysis revealed that gastric emptying rate contributed significantly to models for the severity of these subscales. The importance of discomfort volume disappeared in favour of gender when sex was included in the model. No significant correlations were found with HP status or with gastric accommodation. PAGI-SYM scores are mainly correlated with gastric emptying rate and with gastric hypersensitivity. Multivariate analysis suggests that the questionnaire may be useful in the evaluation of gastroprokinetics. Its role in the evaluation of drugs that alter gastric sensitivity is less clear.
