The characteristics and the prevalence of functional bowel disorders in the general French population are unknown. Based on an epidemiological inquiry in a random population of 1,200 persons who were not seeking care, residents in our country we established: the prevalence of symptoms suggestive of functional bowel disorders; the epidemiological differences between symptomatic subgroups which included abdominal pain with or without bowel dysfunction, diarrhea and constipation. The amount of cases and the prevalence in each subgroup were: abdominal pain, 165, 13.8 p. 100, painless constipation, 75, 6.3 p. 100, diarrhea, 10, 0.8 p. 100. As a whole, functional bowel disorders occurred in 20 p. 100 of our population. The "irritable bowel syndrome" group defined as abdominal pain and/or diarrhea differ from normal subjects by the following higher frequency of age under 50, subjects in active duty, antecedents of diverticulosis, influence of stress on symptoms, nausea, vomiting, migraines, pyrosis and number of visits to a doctor. However neither the sex-ratio nor professional occupation were relevant. The constipation group differed from normal because of the higher frequency of female sex, antecedents of hiatus hernia, use of laxatives but not because of age nor by the number of associated symptoms. In conclusion, functional bowel disorders occurred in 20 p. 100 of our population; two subgroups were clearly different from an epidemiological point of view, the irritable bowel syndrome (13 p. 100) and constipation (7 p. 100); therefore these two groups deserve a specific physiopathological, psychological and therapeutic approach.

Excessive spontaneous swallowing has been associated with a variety of common gastrointestinal symptoms including abdominal pain, heartburn, and bloating and may contribute to disorders such as hiatus hernia, duodenal ulcer, and irritable bowel syndrome. The present study investigated the hypothesis that changes in emotional state alter spontaneous swallowing rate. Subjects were 38 generally healthy undergraduates assigned to either a pleasant low arousal, neutral, or aversive high arousal condition. Each experimental session was divided into 30-min baseline and arousal manipulation periods. Spontaneous swallowing rate increased significantly with emotional arousal: for low, neutral, and high arousal groups, means were 7.9 +/- 1.9 (SE), 15.8 +/- 2.4, and 23.7 +/- 3.6 swallows/30 min, respectively. Other physiological and self-report measures, used to check the effectiveness of the arousal manipulation, varied appropriately with experimental procedures. These results indicate that changes in emotional state alter spontaneous swallowing rate in generally healthy individuals. Further research with patients is needed to establish whether stress-induced increases in swallowing rate produce or exacerbate clinically significant gastrointestinal symptomatology.

To determine the current indications and referral patterns for routine gastrointestinal radiology examinations, 1000 consecutive patients were prospectively analyzed. The following specialties were the largest sources of referral: general internal medicine (38%), gastroenterology (21%), and general and colorectal surgery (17%). Referrals from gastroenterologists were weighted toward areas not well evaluated by endoscopy, such as suspected small bowel disease. The major indications for upper gastrointestinal (GI) examinations were dysphagia and swallowing disorders (32%), hiatus hernia/reflux (14%), and ulcer (14%). Small bowel series were predominantly performed for inflammatory bowel disease (37%), obstruction (25%), and occult blood loss (18%). The majority of combined upper GI/small bowel studies were performed for indications primarily relating to the small bowel. Forty percent of barium enemas were performed for detection of neoplasms and polyps, with pain/irritable colon (14%) and exclusion of leak (14%) the next most common indications. Traditional indications, such as peptic ulcer disease and neoplastic disease, continue to be sources of referral for gastrointestinal radiology. However, more specialized applications, particularly in areas not well suited to endoscopy, such as swallowing disorders, inflammatory disease of the small bowel, and evaluation of surgical anastomoses, are also being commonly used. The changing indications, along with the previously documented decreased volume of gastrointestinal radiologic procedures, should be kept in mind when planning a radiology resident educational curriculum.

Peppermint (Mentha piperita L.) is one of the most widely consumed single ingredient herbal teas, or tisanes. Peppermint tea, brewed from the plant leaves, and the essential oil of peppermint are used in traditional medicines. Evidence-based research regarding the bioactivity of this herb is reviewed. The phenolic constituents of the leaves include rosmarinic acid and several flavonoids, primarily eriocitrin, luteolin and hesperidin. The main volatile components of the essential oil are menthol and menthone. In vitro, peppermint has significant antimicrobial and antiviral activities, strong antioxidant and antitumor actions, and some antiallergenic potential. Animal model studies demonstrate a relaxation effect on gastrointestinal (GI) tissue, analgesic and anesthetic effects in the central and peripheral nervous system, immunomodulating actions and chemopreventive potential. Human studies on the GI, respiratory tract and analgesic effects of peppermint oil and its constituents have been reported. Several clinical trials examining the effects of peppermint oil on irritable bowel syndrome (IBS) symptoms have been conducted. However, human studies of peppermint leaf are limited and clinical trials of peppermint tea are absent. Adverse reactions to peppermint tea have not been reported, although caution has been urged for peppermint oil therapy in patients with GI reflux, hiatal hernia or kidney stones.

In the past decade, the results of many studies on gastrointestinal motility and perception have been published that may be relevant to the clinician. A new classification of oesophageal motor disorders has been proposed in which "ineffective oesophageal motility" largely replaces the former "non-specific oesophageal motor disorders". Recent studies have shown that the incidence of transient lower oesophageal sphincter relaxations can be reduced pharmacologically, and this may open doors to a new therapeutic approach in gastro-oesophageal reflux disease. The mechanisms through which hiatus hernia promotes reflux have become clearer. The recently developed technique of intraluminal impedance monitoring has made it possible to study oesophageal transit, non-acid reflux and its role in the generation of reflux symptoms, as well as the characteristics of belching. Measurement of gastric emptying by means of a non-radioactive isotope and breath-testing has become widely available but, unfortunately, this development has not yet been accompanied by the advent of new therapeutic options for gastroparesis. The term "enteric dysmotility" has been coined for the condition in which upper abdominal symptoms are associated with distinct small intestinal bowel motility disorders in the absence of ileus-like episodes. The role of high-amplitude propagated contractions in the pathogenesis of constipation has been further defined. In cases of suspected sphincter of Oddi dysfunction, manometry of both sphincters (IBD and pancreatic) is now felt to be advisable.

Studies comparing pH-metrically well-characterized gastro-oesophageal reflux disease (GORD) patients with physiological reflux to GORD patients with pathological reflux, with regard to clinical and epidemiological data, are lacking. We included 273 GORD patients with pathological 24-h pH-monitoring (pH+), defined as pH<4 > or = 6% of time. A symptom index (SI) > or = 50% was considered positive, as well as a symptom association probability (SAP) > or = 95%. We included 84 GORD patients with physiological acid exposure (pH-) and a positive SI and/or SAP. Manometry and endoscopy reports were reviewed. Subjects completed questionnaires about demographics and medical history, functional dyspepsia and irritable bowel syndrome, the Nepean Dyspepsia Index symptom score and the RAND-36 quality of life scale. pH- patients were younger (45 vs 50 years, P = 0.003), more often female (60%vs 39%, P = 0.001), smoked more (31%vs 19%, P = 0.021) and reported proton pump inhibition failure more often (47%vs 32%, P = 0.027). A hypotensive lower oesophageal sphincter was less common in pH- patients (18%vs 34%, P = 0.008) and distal oesophageal contraction amplitude was higher (11 vs 9.5 kPa, P = 0.045). pH- patients had hiatal hernia and oesophagitis less often (48%vs 73%, P < 0.0005; 36%vs 54%, P = 0.012 respectively). pH- patients less often reported no other symptoms besides GORD (20%vs 34%, P = 0.015). pH- patients scored worse at the Nepean (reflux 19 vs 12 out of 39, P < 0.0005; dyspepsia 54 vs 38 out of 156, P < 0.0005). In the subgroup of patients who have physiological oesophageal acid exposure the enhancement of the perceived symptom burden appears to be the most important mechanism in GORD pathogenesis.

The aim of this study was to analyze the data of endoscopy and symptoms in 118 Mexican patients with irritable bowel syndrome (IBS), dyspepsia, non-erosive reflux disease (NERD) and erosive esophagitis (EE). IBS criteria were fulfilling for dyspepsia patients in 47%, for NERD in 48%, and for EE patients in 48% of cases. Esophagitis was present in 42% of patients with IBS and in 45% of patients with dyspepsia. A higher prevalence of hiatus hernia was found in EE vs. NERD. Heartburn and acid eructation were associated with the presence of esophagitis; acid eructation, regurgitation and nocturnal pain with duodenitis; and heartburn and regurgitation with hiatus hernia. Males more frequently reported: mucus in feces, abdominal distension, nausea and gastritis; and women more frequently reported esophagitis and duodenitis. Patients with NERD (OR 2.54, 95% CI 1.08 to 5.99, p=0.04), tenesmus and early satiety, and men had an increase risk for reporting hard or lumpy stools. In conclusion, nearly half of the Mexican patients with NERD, EE and dyspepsia fulfill criteria for IBS. A large number of symptoms were correlated with endoscopy, which can be used to improve the indication of the endoscopy and its implementation in clinical studies.

BACKGROUND Migraine is one of the prevalent headaches. Many of patients with migraine, complain of gastrointestinal symptoms. There is limited studies on relation of gastrointestinal symptoms and migraine headache at population level. METHODS In this population-based study, 1038 subjects older than 15 year from a rural area in Fars province, south of Iran. were investigated for functional gastrointestinal disorders. By cluster random sampling, 160 of these persons invited to receive endoscopy along with histopathology samples of upper gastrointestinal tract. Data were analyzed using Pearson chi-square and Fisher exact. RESULTS Mean age of participations were 34.3 years with female to male of 3:1. The prevalence of migraine, irritable bowel syndrome (IBS), reflux, and dyspepsia were 24.6%, 17.7%, 17.4%, and 32.1%, respectively. There were significant relationship between migraine and functional gastrointestinal diseases (odds ratio of association for migraine with IBS, reflux, and dyspepsia were 3.43, 1.68, and 1.68 with p-value < 0.001 for all). In endoscopic findings, only presence of hiatal hernia was associated significantly with migraine (p = 0.011). No histopathologic findings in antral or duodenal biopsies were associated with migraine. CONCLUSION In this population based study we found significant association between migraines and gastrointestinal functional disorders including IBS, reflux and dyspepsia. This may have implication in better management of patients with migraine headache.
