Attention Deficit Hyperactivity Disorder and Functional Defecation Disorders in Children.

OBJECTIVES: The aim of the study was to assess the prevalence of attention deficit hyperactivity disorder (ADHD) in children presenting with functional defecation disorders (FDDs) and to assess the prevalence of FDDs in children with ADHD. METHODS: A cross-sectional cohort study was carried out between September 2014 and May 2016. Group 1: Parents of children with FDDs according to the Rome III criteria completed the Child Behavior Checklist and the VvGK (Dutch questionnaire based on the American Disruptive Behavior Disorder rating scale). Patients with ADHD subarea scores ≥70 on the Child Behavior Checklist and/or ≥16 on the VvGK were referred for further psychiatric evaluation. Group 2: Parents of children treated for ADHD at a specialized ADHD outpatient clinic completed a standardized questionnaire regarding their child's defecation pattern. RESULTS: In group 1 (282 children with FDDs), 10.3% (7.1%-13.5% bias-corrected and accelerate confidence interval) were diagnosed with ADHD. Group 2 consisted of 198 children with ADHD, 22.7% (17.6-28.8 bias-corrected and accelerate confidence interval) fulfilled the Rome III criteria for an FDD. Children with both an FDD and ADHD reported urinary incontinence significantly more often compared to children with an FDD or ADHD alone: 57.1% in FDD + ADHD versus 22.8% in FDD alone (P < 0.001) and 31.1% in ADHD + FDD versus 7.8% in ADHD alone (P < 0.001). CONCLUSIONS: Approximately 10.3% of children with FDDs had ADHD and 22.7% of children with a known diagnosis of ADHD fulfilled the Rome III criteria for an FDD. This observation suggests that screening for behavioral disorders and FDDs should be incorporated into the diagnostic workup of these groups of children.

Impacto de la instauración de un protocolo de actuación clínica ante el dolor abdominal en urgencias pediátricas / Impact of establishment of a clinical protocol for abdominal pain in pediatric emergencies

Objetivos: En enero de 2013 se implantó un protocolo de actuación para el manejo del dolor abdominal en el servicio de urgencias de pediatría, que pretendía reducir la realización de radiografías de abdomen no indicadas, disminuir la administración de enemas no indicados y aplicar una pauta de analgesia mayor. Se ha revisado el impacto del protocolo sobre la modificación de la práctica clínica y si estas variaciones se mantienen. Material y métodos: Estudio observacional, descriptivo, analítico y retrospectivo, realizado en 684 pacientes que acudieron al servicio de urgencias por presentar dolor abdominal de causa aparentemente no orgánica, distribuidos en cuatro periodos: diciembre de 2012 (P1), febrero de 2013 (P2), noviembre de 2013 (P3) y mayo de 2015 (P4). Se han recogido los datos sobre las pruebas diagnósticas realizadas y los tratamientos empleados en estos pacientes.

Tratamiento con polietilenglicol: P1= 4,3%, P2= 6,3%, P3= 9,8%, P4= 4,7% (p >0,05); pacientes con estreñimiento: P1= 12,8%, P2= 21,6%, P3= 40,6%, P4= 20,5% (p= 0,034). Pauta de analgesia: P1= 42,9%, P2= 53,5%, P3= 53,7%, P4= 62,7% (p= 0,02). Reconsultas al servicio de urgencias: P1= 10,4%, P2= 2,1%, P3= 1,8%, P4= 13% (p <0,01). Conclusiones: El protocolo ha logrado reducir de forma significativa la realización de radiografías abdominales y el empleo de enemas rectales. Ha aumentado la prescripción de analgesia en pacientes con dolor abdominal. El protocolo ha logrado homogeneizar la actuación de los profesionales, disminuyendo el riesgo de yatrogenia y aumentando el confort de los pacientes y sus familias (AU)

Objectives: In January 2013 a protocol for the management of abdominal pain at pediatric emergency was implanted, with the following objectives: reducing abdominal radiographs not indicated, reduce treatment with enemas not indicated and more prescription of analgesia. It has been reviewed the impact of the protocol on changing clinical practice and whether these variations are maintained. Material and methods: Retrospective, descriptive and analytical observational study with 684 patients attending emergency department for abdominal pain apparently no organic cause, divided into four periods: December 2012 (P1), February 2013 (P2), November 2013 (P3) and May 2015 (P4). We collected data about diagnostic tests performed and treatments used in these patients. Results: Abdominal radiography: P1= 14.7%, P2= 6.9%, P3= 1.8%, P4= 0% (p <0.01); constipated patients: P1= 23.4%, P2= 13.5%, P3= 0%, P4= 0% (p= 0.001). Abdominal ultrasound: P1= 11%, P2= 12.5%, P3= 9.4%, P4= 10.1% (p >0.05). Patients treated with rectal enema: P1= 21.5%, P2= 8.3%, P3= 17.1%, P4= 11.7% (p= 0.005); constipated patients: P1= 51.1%, P2= 21.6%, P3= 31.3%, P4= 32.5% (p= 0.036). Patients treated with polyethylenglycol: P1= 4.3%, P2= 6.3%, P3= 9.8%, P4= 4.7% (p >0.05); constipated patients: P1= 12.8%, P2= 21.6%, P3= 40.6%, P4= 20.5% (p= 0.034). Patients treated with analgesia: P1= 42.9%, P2= 53.5%, P3= 53.7%, P4= 62.7% (p= 0.02). Reconsultations the emergency department: P1= 10.4%, P2= 2.1%, P3= 1.8%, P4= 13% (p <0.01). Conclusions: The protocol has reduced significantly the performance of abdominal radiographs and use of rectal enemas. It has increased the prescription of analgesia in patients with abdominal pain. Protocol has managed to standardize the medical intervention, reducing the risk of iatrogenic and increasing comfort for patients and their families (AU)

Trastornos funcionales y motores digestivos / Functional and motor gastrointestinal disorders

En este artículo se comentan los trabajos sobre trastornos funcionales y motores digestivos presentados en el congreso de la American Association of Gastroenterology (Digestive Diseases Week) del año 2015 que nos han parecido de mayor interés. Se siguen buscando biomarcadores para el síndrome del intestino irritable y, en este sentido, se han presentado nuevos datos. Se presentó un estudio que confirma que el uso de los antidepresivos a dosis bajas tiene efecto antinociceptivo y que no modifican los aspectos psicológicos de los pacientes con dispepsia funcional. Una aportación que podría ser de aplicabilidad inmediata es el uso de acupuntura eléctrica transcutánea, que ha demostrado ser eficaz en el control de la náusea en pacientes con gastroparesia. Se siguen aportando datos de la importancia de la dieta en el intestino irritable, aunque parece que la eficacia de la dieta baja en FODMAP está perdiendo fuelle con el tiempo. Se han comunicado múltiples datos de la eficacia a largo plazo del tratamiento con rifaximina en pacientes con intestino irritable con diarrea. Además, entre otras aportaciones, y más como curiosidad, se presentó un estudio que valoraba el efecto de la histamina en la dieta en pacientes con síndrome del intestino irritable

This article discusses the most interesting studies on functional and motor gastrointestinal disorders presented at Digestive Diseases Week (DDW), 2015. Researchers are still seeking biomarkers for irritable bowel syndrome and have presented new data. One study confirmed that the use of low-dose antidepressants has an antinociceptive effect without altering the psychological features of patients with functional dyspepsia. A contribution that could have immediate application is the use of transcutaneous electroacupuncture, which has demonstrated effectiveness in controlling nausea in patients with gastroparesis. New data have come to light on the importance of diet in irritable bowel syndrome, although the effectiveness of a low-FODMAP diet seems to be losing momentum with time. Multiple data were presented on the long-term efficacy of rifaximin therapy in patients with irritable bowel syndrome and diarrhoea. In addition, among other contributions, and more as a curiosity, a study evaluated the effect of histamine in the diet of patients with irritable bowel syndrome

Prevalence of functional bowel disorders and faecal incontinence: an Australian primary care survey.

AIM: Interest in functional bowel disorders (FBDs) and faecal incontinence (FI) has increased amongst coloproctologists. The study aimed to assess the prevalence of FBDs and FI (including its severity) among Australian primary healthcare seekers using objective criteria. METHOD: A cross-sectional survey was conducted in a primary care setting in Sydney, Australia. A self-administered questionnaire was used to collect demographic information and diagnose FBDs (irritable bowel syndrome, constipation, functional bloating and functional diarrhoea) based on Rome III criteria. The severity of FI was determined using the Vaizey incontinence score. Associations with medical/surgical history and healthcare utilization were assessed. RESULTS: Of 596 subjects approached, 396 (66.4%) agreed to participate. Overall, 33% had FBD and/or FI. Irritable bowel syndrome was present in 11.1% and these participants were more likely to report anxiety/depression (P < 0.01) and to have had a previous colonoscopy (P < 0.001) or cholecystectomy (P = 0.02). Functional constipation was present in 8.1%, and functional bloating and functional diarrhoea were diagnosed in 6.1%, and 1.5%, respectively. FI was present in 12.1% with the majority (52%) reporting moderate/severe incontinence (Vaizey score > 8). Participants with FI were more likely to have irritable bowel syndrome, urinary incontinence and previous anal surgery (P < 0.01). CONCLUSION: FBDs and FI are prevalent conditions amongst primary healthcare seekers and the needs of those affected appear to be complex given their coexisting symptoms and conditions. Currently, the majority do not reach colorectal services, although increased awareness by primary care providers could lead to sufferers being referred for specialist management.

Prevalence of colonic motor or evacuation disorders in patients presenting with chronic nausea and vomiting evaluated by a single gastroenterologist in a tertiary referral practice.

BACKGROUND: Nausea and vomiting are thought to result from upper gastrointestinal dysfunctions. Our clinical observations led to the hypothesis that colonic motor dysfunction is associated with nausea and vomiting. METHODS: We reviewed electronic medical records (EMR) of 149 patients presenting with complaints of nausea and/or vomiting in a tertiary gastroenterology practice to investigate the association with disorders of colonic motor or evacuation disorders. We extracted demographics, gastric emptying (GE in 149) and colonic transit (CT in 138) of solids, ascending colon emptying half-time (AC t1/2 ), rectal evacuation by anorectal manometry (ARM) in 91 and balloon expulsion test (BE) in 55 patients. We estimated the proportions with delayed GE or CT, based on the 5th percentile of GE (in 319) and CT in 220 healthy volunteers using same method. KEY RESULTS: Among 11 patients with nausea and/or vomiting with only GE measured, five had delayed and six normal GE. Among the 149 patients, 77 (52%) patients had evacuation disorders, confirmed by objective tests in 68 patients, and clinical examination in nine patients. In the 138 patients with both GE and CT measured, 106 (76%) had both normal GE and CT, 11 (8%) only delayed GE, 16 (11%) normal GE with delayed CT, and five (3%) delayed GE and CT. Among 21 patients (15%) with delayed CT, nine had slow AC t1/2 and 12 evacuation disorder. CONCLUSIONS & INFERENCES: In patients with chronic nausea and/or vomiting in gastroenterology practice, evaluation of colonic motility and rectal evacuation should be considered, since about half the patients have abnormal functions that conceivably contribute to the presenting nausea and/or vomiting.

Prevalence and co-occurrence of upper and lower functional gastrointestinal symptoms in patients eligible for bariatric surgery.

BACKGROUND: Obesity is considered as a risk factor for many functional digestive disorders. The aim of the present study was to evaluate the prevalence and the association of functional digestive symptoms affecting the upper and the lower digestive tract in patients eligible for bariatric surgery. METHODS: Before surgery, 120 consecutive patients with normal upper endoscopy (7.5% males, mean BMI 44 ± 6 m/kg(2)) have filled a standard questionnaire in order to evaluate the presence of depressive symptoms and functional digestive disorders according to the Rome criteria. The major symptoms (esophageal, gastroduodenal, anorectal, and abdominal pain) were coded as dichotomous variables. Data analysis was performed using multivariate logistic regression with a backwards selection procedure adjusted only for the variables that were significant in univariate analysis (p < 0.05). RESULTS: Functional symptoms were present in 89% of the subjects (2.5 functional digestive symptoms/subject). Depression symptoms were found in 43% of the patients. Esophageal symptoms were independent predictors for the presence of gastric, bowel, and anorectal symptoms. Functional abdominal pain and bowel symptoms were present, respectively, in 19% and 84% of the patients. Approximately half of the patients have specific functional bowel disorders (28.6% constipation, 18% irritable bowel syndrome, 18% diarrhea, 1% bloating) and 35.7% have non-specific bowel disorders. Anorectal symptoms were found in 40% of the patients: difficult defecation in 32% and fecal incontinence in 9.8% of the patients. Depression was an independent predictor for anorectal symptoms. CONCLUSIONS: This study shows the high prevalence of functional bowel symptoms in patients complaining of morbid obesity.

Trastornos funcionales y motores digestivos / Functional and motor gastrointestinal disorders

Padecer un trastorno funcional digestivo (TFD) no es fácil. Muchos pacientes preferirían tener una enfermedad orgánica y un informe médico en el que se describiesen los resultados de alguna prueba concluyendo que se observa una lesión. Por tanto, es fundamental adquirir nuevos conocimientos sobre las causas y tratamientos de estas dolencias. El objetivo de este capítulo es resumir de la manera más fácil y útil posible los trabajos más relevantes sobre TFD y trastornos motores digestivos presentados en el Congreso de la Asociación Americana de Gastroenterología (DDW 2010).Lo más destacable se refiere al estudio de los mecanismos patogénicos y búsqueda de nuevas terapias en trastornos muy prevalentes, como la dispepsia funcional, el síndrome del intestino irritable o el estreñimiento, pero también ha habido estudios interesantes en incontinencia, gastroparesia, síndrome de vómitos cíclicos o acalasia. Cada vez está más claro que los TFD son de origen multifactorial y que tanto los factores genéticos como ambientales, psicológicos, microinflamatorios y neuroinmunoendocrinos forman parte de su complejo puzle. Cada año somos partícipes de los avances que se producen en el ámbito mundial con la esperanza de que repercutan en el bienestar de nuestros paci (AU)

Functional gastrointestinal (GI) disorders are difficult to live with. Many patients would prefer to have an organic disease and a medical report stating the results of a test providing evidence of a lesion. Therefore, further knowledge of the causes and treatment of these disorders is essential. The present article aims to summarize as simply and usefully as possible the most important studies on functional and motor GI disorders presented at the Congress of the American Gastroenterological Association (Digestive Disease Week 2010).The most notable presentations concerned the pathogenic mechanisms and search for new therapies in highly prevalent disorders such as functional dyspepsia, irritable bowel syndrome and constipation but interesting studies were also presented on incontinence, gastroparesis, cyclic vomiting syndrome and achalasia. It is increasingly clear that functional GI disorders are caused by multiple factors and, therefore, that genetic, environment, psychological, microinflammatory and neuroimmune-endocrine factors form part of this complex puzzle. Each year, advances are made in distinct parts of the world, which will hopefully improve patient well-being (AU)

Functional bowel disorders in Iranian population using Rome III criteria.

BACKGROUND/AIM: To study the prevalence and risk factors of functional bowel disorders (FBD) in Iranian community using Rome III criteria. MATERIALS AND METHODS: This study was a cross-sectional household survey conducted from May 2006 to December 2007 in Tehran province, Iran, including 18,180 participants who were selected randomly and interviewed face-to-face by a validated questionnaire based on Rome III criteria. RESULTS: In all, 1.1% met the Rome III criteria for irritable bowel syndrome (IBS), 2.4% for functional constipation (FC), and 10.9% of the participants had any type of FBD. Among participants with functional dyspepsia, 83.8% had FBD; the majority cases were unspecified functional bowel disorder (U-FBD). Of the subjects fulfilling the IBS criteria, IBS with constipation (52%) was the most frequent subtype. In the multivariate analysis, women had a higher risk of any FBDs than men, except for functional diarrhea (FD). The prevalence of FBD, FC and FD increased and IBS decreased with increasing age. Marital status was only associated with a decrease in the risk of FBD and FD, respectively. IBS subtypes compared with FC and FD. There was no significant difference between FC and IBS with constipation (IBS-C), except for self-reported constipation; while, IBS with diarrhea (IBS-D) had more symptoms than FD. CONCLUSION: This study revealed a low rate of FBDs among the urban population of Tehran province. The ROME III criteria itself, and the problems with interpretation of the data collection tool may have contributed in underestimating the prevalence of FBD. In addition the reliability of recall over 6 months in Rome III criteria is questionable for our population.

Travel and travelers' diarrhea in patients with irritable bowel syndrome.

This study evaluated occurrence of travel and travelers' diarrhea in patients with irritable bowel syndrome (IBS). A survey was mailed to 591 patients of a clinical practice who had IBS. Based on survey responses, patients were categorized as having IBS, post-infectious IBS (PI-IBS), unclassified functional bowel disorder (UFBD), or post-infectious UFBD (PI-UFBD). Of 201 persons who returned questionnaires meeting inclusion criteria, 57.7%, 11.4%, 24.9%, and 6.0% had IBS, UFBD, PI-IBS, and PI-UFBD, respectively. Travel during six months before illness onset was more common in patients with PI-IBS or PI-UFBD than in persons with idiopathic IBS or UFBD (P = 0.006). Survey results demonstrated that 16.1% of post-infectious bowel disorder cases and 7.5% of overall IBS cases in a general medical population developed chronic disease within six months of an international trip. Symptoms of established functional bowel disorder in each clinical category were shown to worsen after travel-related acute diarrhea.

Pain symptoms and stooling patterns do not drive diagnostic costs for children with functional abdominal pain and irritable bowel syndrome in primary or tertiary care.

OBJECTIVE: The objectives of this study were to (1) compare the cost of medical evaluation for children with functional abdominal pain or irritable bowel syndrome brought to a pediatric gastroenterologist versus children who remained in the care of their pediatrician, (2) compare symptom characteristics for the children in primary versus tertiary care, and (3) examine if symptom characteristics predicted the cost of medical evaluation. METHODS: Eighty-nine children aged 7 to 10 years with functional abdominal pain or irritable bowel syndrome seen by a gastroenterologist (n = 46) or seen only by a pediatrician (n = 43) completed daily pain and stool diaries for 2 weeks. Mothers provided retrospective reports of their children's symptoms in the previous year. Cost of medical evaluation was calculated via chart review of diagnostic tests and application of prices as if the patients were self-pay. RESULTS: Child-reported diary data reflected no significant group differences with respect to pain, interference with activities, or stool characteristics. In contrast, mothers of children evaluated by a gastroenterologist viewed their children as having higher maximum pain intensity in the previous year. Excluding endoscopy costs, cost of medical evaluation was fivefold higher for children evaluated by a gastroenterologist, with higher cost across blood work, stool studies, breath testing, and diagnostic imaging. Symptom characteristics did not predict cost of care for either group. CONCLUSIONS: Despite the lack of difference in symptom characteristics between children in primary and tertiary care, a notable differential in cost of evaluation exists in accordance with level of care. Symptom characteristics do not seem to drive diagnostic evaluation in either primary or tertiary care. Given the lack of differences in child-reported symptoms and the maternal perspective that children evaluated by a gastroenterologist had more severe pain, we speculate that parent perception of child symptoms may be a primary factor in seeking tertiary care.

Alterations in the intestinal microbiota and functional bowel symptoms.

Functional gastrointestinal disorders (FGIDs) are highly prevalent in Western countries yet no single mechanism or etiological agent that initiates IBS has been identified. Current research has implicated the intestinal microbiota with FGIDs. This article reviews the available literature/data regarding the intestinal microbiota and FGIDS. The possible relationships between the intestinal microbiota and the intestinal function and functional bowel symptoms are discussed.

Applying case definition criteria to irritable bowel syndrome.

OBJECTIVE: The quality of documentation of signs and symptoms and validation of the diagnosis of irritable bowel syndrome (IBS) according to case definition criteria of Manning, Rome I and Rome II in an office setting has not been previously described. We sought to identify and validate cases of IBS based on the Manning, Rome I and Rome II diagnostic criteria in a rural practice setting. SETTING: Marshfield Epidemiologic Study Area (MESA) Central consisting of 14 ZIP codes in central Wisconsin, USA. METHODS: A retrospective cohort study involved 890 patients with the diagnostic codes 564.1 for irritable bowel syndrome and 306.4 spastic colon-psychogenic who had presented to the practice from 1993-2003. Duration, frequency, concordance and intensity of symptoms based on case definitions of IBS were abstracted from the medical records. RESULTS: During the study period, 890 incident cases of IBS were identified. Only 404 met one or more of the three diagnostic criteria, 340 (84%) met only the Manning criteria, 35 (10%) met only Manning and Rome I criteria, 4 (1%) met both Manning and Rome II criteria, and 25 (6%) met Manning and Rome I and Rome II criteria. Age adjusted incidence rates per 100,000 person-years for validated IBS cases during the observational period were 87 to 170 by Manning (lower confidence interval [CI]: 57-127, upper CI: 116-213), 8 to 34 (lower CI: 0-14, upper CI: 16-53) for Rome I and 3 to 16 (lower CI: 0-3, upper CI: 8-28) for Rome II. Comparison of Rome I and Rome II showed moderate concordance (kappa statistic = 0.51; 95% CI: 0.39-0.64). CONCLUSIONS: Only a small percentage of IBS cases with assigned diagnostic codes met case definition criteria for IBS. There were low concordance rates among the three diagnostic criteria applied.

Prevalence and risk factors for abdominal bloating and visible distention: a population-based study.

BACKGROUND: Abdominal bloating and visible distention are common yet poorly understood symptoms. Epidemiological data distinguishing visible distention from bloating are not available. We aimed to evaluate the prevalence and potential risk factors for abdominal bloating and visible distention separately in a representative US population, and their association with other functional gastrointestinal disorders (FGIDs). METHODS: The validated Talley Bowel Disease Questionnaire was mailed to a cohort selected at random from the population of Olmsted County, Minnesota. The complete medical records of responders were abstracted; 2259 subjects (53% females; mean age 62 years) provided bloating and distention data. RESULTS: The age and sex-adjusted (US White 2000) overall prevalence per 100 for bloating was 19.0 [95% confidence interval (CI), 16.9 to 21.2] vs 8.9 (95% CI, 7.2 to 10.6) for visible distention. Significantly increased odds for bloating alone and separately for distention (vs neither) were detected in females, and in those with higher overall Somatic Symptom Checklist (SSC) scores and higher scores of each individual SSC item. Further, females [odds ratio (OR), 1.5; 95% CI, 1.0 to 2.1], higher SSC score (OR, 1.4; 95% CI, 1.1 to 1.8), constipation-predominant irritable bowel syndrome (OR, 2.3; 95% CI, 1.3 to 4.1), dyspepsia (OR, 1.9; 95% CI, 1.1 to 3.2), and gastro-intestinal symptom complex overlap (OR, 1.7; 95% CI, 1.1 to 2.7) significantly increased odds for distention over bloating alone. CONCLUSIONS: Bloating and distention are common and have similar risk factors; somatisation probably plays a role.

Abdominal bloating in employed adults: prevalence, risk factors, and association with other bowel disorders.

UNLABELLED: BACKGROUND Bloating is common, but its significance as a marker of underlying disease has not been defined. AND AIMS: We report on risk factors for bloating, its relationship to physical activity and quality of life (QOL), and its predictive value for functional bowel disorders. METHODS: This is a cross-sectional population-based study of 1,069 employees of the Veterans Affairs Black Hills Health Care System. The validated Bowel Disease Questionnaire was used to identify subjects with abdominal bloating and other bowel disorders. The association of bloating with QOL was assessed using the SF36 (Short-Form 36) questionnaire. Physical activity was assessed using the modified Baecke questionnaire. RESULTS: The response rate was 72% (723 of 1,069). Bloating was reported by 21% of all subjects (95% confidence interval [CI] 17.7-23.7), 64% with irritable bowel syndrome (IBS), 35% with non-IBS constipation, 23% with non-IBS diarrhea, and 42% with dyspepsia. Functional bloating (i.e., bloating in the absence of other bowel disorders) was reported by 7% of subjects (95% CI 5.2-9.0). Of those with bloating, 28% had IBS, 25% non-IBS constipation, 8% non-IBS diarrhea, and 30% dyspepsia. The positive and negative predictive values of bloating in the diagnosis of functional bowel disorder were 66% and 87%, respectively. The only risk factors were smoking and high-dose aspirin. Bloating was not associated with physical activity. QOL on all subscales of SF36 was lower in subjects with bloating than those without bloating. CONCLUSIONS: Bloating is a common symptom in otherwise healthy adults, and is often associated with but not predictive of functional bowel disorders. Smoking and high-dose aspirin are associated with bloating while physical activity is not.

Epidemiology of slow and fast colonic transit using a scale of stool form in a community.

BACKGROUND: Measurement of gastrointestinal transit is commonly performed in the clinic, but data on transit in the community are lacking. AIM: To estimate the prevalence of slow and fast colonic transit using stool form, and potential risk factors. METHODS: A validated self-reported gastrointestinal symptom questionnaire was mailed to 4196 randomly selected members of the community (response rate 54%). One question asked the subject to self-report their stool form using the Bristol Stool Scale. RESULTS: Overall, 18%, 9% and 73% met stool form criteria for slow, fast or normal colonic transit, respectively. Increased odds for slow transit were observed with a higher Somatic Symptom Checklist score (OR = 1.6; 1.3-2.0), while a decreased odds for slow transit was observed in males relative to females (OR = 0.6; 0.5-0.8). An increased odds for fast transit was observed with higher Somatic Symptom Checklist score (OR = 2.3; 1.7-2.9) and a history of cholecystectomy (OR = 1.8; 1.2-2.8). Increasing body mass index (per 5 units) was associated with decreased odds for slow (OR = 0.85; 0.78-0.93), and an increased odds for fast (OR = 1.1; 1.04-1.24) colonic transit. CONCLUSION: Based on stool form assessment, nearly one in five community members may have slow colonic transit and one in 12 have accelerated colonic transit.

[An epidemiologic study of functional bowel disorders in adolescents in China].

OBJECTIVE: To explore the most common bowel frequency and the prevalence rates of functional bowel disorders among adolescents in China. METHODS: A questionnaire survey was conducted among 51,956 students from high and primary schools in 6 Chinese cities distributed in the whole China collected by stratified, randomized, cluster sampling to study the epidemiology of functional bowel disorders. RESULTS: (1) 88.05% +/- 0.28% of the students had bowel frequency between 1 - 2 times/day and 1 time/two days. Girl students were found to have a lower bowel frequency than boy students (P < 0.01). (2) The prevalence rates of irritable bowel syndrome, chronic constipation, and chronic diarrhea were 20.19% (10 490), 25.92% (13 467), and 8.77% (4557) respectively. CONCLUSION: (1) The normal bowel frequency among adolescents in China may be defined as bowel movements between 1 - 2 times per day and 1 time per two days. (2) Irritable bowel syndrome, chronic constipation and chronic diarrhea are common disorders among the adolescents in China.

A comparative reappraisal of the Rome II and Rome III diagnostic criteria: are we getting closer to the 'true' prevalence of irritable bowel syndrome?

OBJECTIVES: Revisions of the diagnostic criteria for irritable bowel syndrome have led to varying prevalence estimates. The Rome III criteria require a lower symptom frequency than Rome II (at least 10% of the time for Rome III, compared with at least 25% of the time for Rome II). In an epidemiological survey of a representative sample of Israeli adults using Rome II, we reported the prevalence for irritable bowel syndrome as 2.9%. The official Rome II integrative questionnaire, used for that study, enables a close approximation of Rome III rates, facilitating a retrospective comparison of these criteria. METHODS: A representative sample of 1000 adults was interviewed with a validated Hebrew version of the official Rome II integrative questionnaire. The data were re-evaluated retrospectively to compare the Rome II results with a close approximation of the new Rome III criteria. RESULTS: The prevalence rates for irritable bowel syndrome were 2.9 and 11.4%, respectively, for Rome II and Rome III. The corresponding consultation rates were 57.1 and 41.7%, indicating that the more strict Rome II criteria may select out a group of patients with more severe disease or greater psychosocial problems. Women made up 71.4% of irritable bowel syndrome by Rome II and 62.5% by Rome III. CONCLUSIONS: In the present retrospective study, the prevalence rate for irritable bowel syndrome in our population is significantly higher by Rome III compared with Rome II. Rome III may more closely reflect the socioeconomic burden of irritable bowel syndrome compared with the overly strict Rome II. Prospective comparative studies should be conducted to confirm these results.
