Orexins are neuropeptides that are localized in neurons within the lateral hypothalamic area and regulate feeding behavior. The lateral hypothalamic area plays an important role in not only feeding but the central regulation of other functions including gut physiology. Accumulating evidence have shown that orexins acts in the brain to regulate a wide variety of body functions including gastrointestinal functions. The purpose of this review is to summarize relevant findings on brain orexins and a digestive system, and discuss the pathophysiological roles of the peptides with special reference to functional gastrointestinal disorders. Exogenously administered orexin or endogenously released orexin in the brain potently stimulates gastric acid secretion in pylorus-ligated conscious rats. The vagal cholinergic pathway is involved in the orexin-induced stimulation of acid secretion, suggesting that orexin-containing neurons in lateral hypothalamic area activates neurons in the dorsal motor nucleus in medulla oblongata, followed by increasing vagal outflow, thereby stimulating gastric acid secretion. In addition, brain orexin stimulates gastric motility, pancreatic secretion and induce gastroprotective action. On the other hand, brain orexin is involved in a number of physiological functions other than gut physiology, such as control of sleep/awake cycle and anti-depressive action in addition to increase in appetite. From these evidence, we would like to make a hypothesis that decreased orexin signaling in the brain may play a role in the pathophysiology in a part of patients with functional gastrointestinal disorders who are frequently accompanied with appetite loss, sleep disturbance, depressive state and the inhibition of gut function. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

The aim of this study was to describe the complementary and alternative medicine methods most commonly used to alleviate symptom distress in persons with functional gastrointestinal disorders. People with functional gastrointestinal disorders face many challenges in their everyday lives, and each individual has his/her own way of dealing with this illness. The experience of illness often leads persons with functional gastrointestinal disorders to complementary and alternative medicine as a viable healthcare choice. Quantitative and describing design. A study-specific complementary and alternative medicine questionnaire was used, including questions about complementary and alternative medicine methods used and the perceived effects of each method. Efficacy assessments for each method were preventive effect, partial symptom relief, total symptom relief or no effect. A total of 137 persons with functional gastrointestinal disorders answered the questionnaire, 62% (n = 85) women and 38% (n = 52) men. A total of 28 different complementary and alternative medicine methods were identified and grouped into four categories: nutritional, drug/biological, psychological activity and physical activity. All persons had tried at least one method, and most methods provided partial symptom relief. Persons with functional gastrointestinal disorders commonly use complementary and alternative medicine methods to alleviate symptoms. Nurses have a unique opportunity to expand their roles in this group of patients. Increased knowledge of complementary and alternative medicine practices would enable a more comprehensive patient assessment and a better plan for meaningful interventions that meet the needs of individual patients. © 2011 Blackwell Publishing Ltd.

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.

Yu, Xiaoyun; Yu, Mingran; Liu, Yingzhe; Yu, Shaoyong

2016-05-01

Transient receptor potential (TRP) channels are predominantly distributed in both somatic and visceral sensory nervous systems and play a crucial role in sensory transduction. As the largest visceral organ system, the gastrointestinal (GI) tract frequently accommodates external inputs, which stimulate sensory nerves to initiate and coordinate sensory and motor functions in order to digest and absorb nutrients. Meanwhile, the sensory nerves in the GI tract are also able to detect potential tissue damage by responding to noxious irritants. This nocifensive function is mediated through specific ion channels and receptors expressed in a subpopulation of spinal and vagal afferent nerve called nociceptor. In the last 18 years, our understanding of TRP channel expression and function in GI sensory nervous system has been continuously improved. In this review, we focus on the expressions and functions of TRPV1, TRPA1, and TRPM8 in primary extrinsic afferent nerves innervated in the esophagus, stomach, intestine, and colon and briefly discuss their potential roles in relevant GI disorders.

Recurrent abdominal pain (RAP) is a common complaint in children. Significant portion of them are of functional origin. This study aimed to assess the prevalence of abdominal pain-predominant functional gastrointestinal disorder (FGID) and its types in Jordanian school children. This is a school-based survey at south Jordan. Information using the self-reporting form of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-RIII) - the official Arabic translation - was collected. Classes from academic years (grades) 6 - 8 were selected. SPSS Statistical Package Version 17 (IBM, Armonk, NY, USA) was used. Categorical data were analyzed using Fisher's exact test, and continuous data were analyzed using t -test. P abdominal pain-predominant FGID. Seventy-nine (68%) of them were females. Forty-seven (10.6%) had irritable bowel syndrome (IBS). Thirty-six (8%), 17 (3.8%), 11 (2.4%) and five (1.1%) had abdominal migraine, functional abdominal pain, functional abdominal pain syndrome and functional dyspepsia, respectively. Abdominal pain-predominant FGID has become a major health issue in Jordanian children. One of four children between the ages of 11 and 15 years exhibits at least one abdominal pain-predominant FGID. The most common form of abdominal pain-predominant FGID in our children was IBS. Females are affected more often than males. Intestinal and extra-intestinal symptoms are seen regularly with abdominal pain-predominant FGIDs.

Curcumin is a natural polyphenol extracted from the turmeric rhizome, which has a wide range of biological activities, but until now the effects of curcumin on the gastrointestinal peristalsis have not been fully understood. In vivo study, we observed the effects of curcumin on gastric emptying and intestinal propulsion rates of mice in normal state and in delayed state by atropine (ATR) or nitric oxide precursor L-arginine (L-Arg). An in vitro study explored the direct effects of curcumin on the intestinal contractility, but were studied through measuring spontaneous contraction of isolated jejunum of mice. Our results showed that intragastric administration of curcumin (200 mg/kg/day) for 10-20 days significantly improved gastric emptying and intestinal propulsion rates of mice delayed by ATR. Moreover, intragastric administration of curcumin (200 mg/kg/day) for 15 days also significantly improved mice gastric emptying and intestinal propulsion rates delayed by L-Arg. There was no significant effect on normal gastrointestinal propulsion of mice after intragastric administration of curcumin (200 mg/kg/day) for 1-20 days. When normal isolated jejunum of mice were incubated with curcumin in vitro, the amplitude of the spontaneous contractile waves of jejunum was reduced in a concentration-dependent manner. Moreover, curcumin reduced the amplitude of the contractile waves of jejunum in both contracted and relaxed state induced by acetylcholine or ATR individually. Taken together, our results suggest that curcumin has quite different effects on gastrointestinal peristalsis in vivo and in vitro. Moderate dose of curcumin by intragastric administration for more than 10 days can alleviate the functional gastrointestinal disorders of mice, but cannot affect normal gastrointestinal propulsion.

Full Text Available Abstract Background Functional gastrointestinal disorders (FGID may occur following acute gastroenteritis. This long-term complication has previously not been described after infection with the non-invasive protozoan Giardia lamblia. This study aims to characterize persistent abdominal symptoms elicited by Giardia infection according to Rome II criteria and symptoms scores. Methods Structured interview and questionnaires 12–30 months after the onset of Giardia infection, and at least 6 months after Giardia eradication, among 82 patients with persisting abdominal symptoms elicited by the Giardia infection. All had been evaluated to exclude other causes. Results We found that 66 (80.5% of the 82 patients had symptoms consistent with irritable bowel syndrome (IBS and 17 (24.3% patients had functional dyspepsia (FD according to Rome II criteria. IBS was sub classified into D-IBS (47.0%, A-IBS (45.5% and C-IBS (7.6%. Bloating, diarrhoea and abdominal pain were reported to be most severe. Symptoms exacerbation related to specific foods were reported by 45 (57.7% patients and to physical or mental stress by 34 (44.7% patients. Conclusion In the presence of an IBS-subtype pattern consistent with post-infectious IBS (PI-IBS, and in the absence of any other plausible causes, we conclude that acute Giardia infection may elicit functional gastrointestinal diseases with food and stress related symptoms similar to FGID patients in general.

Many patients with functional gastrointestinal disorders (FGIDs) rank sensations of bloating and distension among their most debilitating symptoms. Previous studies that have examined intestinal gas volume (IGV) in patients with FGIDs have employed a variety of invasive and imaging techniques. These studies are limited by small numbers and have shown conflicting results. The aim of our study was to estimate, using CT of the abdomen and pelvis (CTAP), IGV in patients attending FGID clinic and to compare IGV in patients with and without FGID. All CTAP (n = 312) performed on patients (n = 207) attending a specialized FGID clinic over 10-year period were included in this study. Patients were classified into one of 3 groups according to the established clinical grading system, as organic gastrointestinal disorder (OGID, ie, patients with an organic non-functional disorder, n = 84), FGID (n = 36) or organic and functional gastrointestinal disorder (OFGID, ie, patients with an organic and a functional disorder, n = 87). Two independent readers blinded to the diagnostic group calculated IGV using threshold based 3D region growing with OsiriX. Median IGVs for the FGID, OGID, and OFGID groups were 197.6, 220.6 and 155.0 mL, respectively. Stepwise linear regression revealed age at study, gender, and calculated body mass index to predict the log IGV with an r(2) of 0.116, and P IGV in OGID (Spearman's = 0.253, P = 0.02) but this correlation was non-significant in the other groups. Although bloating is a classic symptom in FGID patients, IGV may not be increased compared with OGID and OFGID patients.

Functional Gastrointestinal disorders (FGID) are common disorders in gastroenterology which are common in young adults. The aim of this study is evaluating the prevalence of upper FGID in iranian young adults. This was a cross-sectional study which was on 995 persons who were going to marry. A ROME III based questionnaire was used to determine the frequency of upper GI Syndromes among the sample population. Our results determined 74 subjects had functional dyspepsia (36 subjects diagnosed as postprandial distress syndrome patient and Epigastric pain syndrome was seen in 38 subjects). Functional heartburn was diagnosed in 52 participants. Globus was seen in 35 subjects and 41 had unspecified excessive belching. Many epidemiologic studies were done all around the world but there are different reports about prevalence and incidence of FGIDs. Our results were agreed with reported prevalence of FGIDs in Iran in adults. And our findings were agreed with some other Asian studies.

Full Text Available ObjectiveTo investigate the illness perception characteristics of Chinese patients with functional gastrointestinal disorders (FGID, and the mediating role between symptoms, psychopathology, and clinical outcomes.MethodsSix illness groups from four outpatient departments of a general hospital in China were recruited, including the FGID patient group. The modified and validated Chinese version of the illness perception questionnaire-revised was utilized, which contained three sections: symptom identity, illness representation, and causes. The 12-item short-form health survey was utilized to reflect the physical and mental health-related quality of life (HRQoL. The Toronto alexithymia scale was used to measure the severity of alexithymia. Additional behavioral outcome about the frequency of doctor visits in the past 12 months was measured. Pathway analyses with multiple-group comparisons were conducted to test the mediating role of illness perception.ResultsOverall, 600 patients were recruited. The illness perceptions of FGID patients were characterized as with broad non-gastrointestinal symptoms (6.8 ± 4.2, a negative illness representation (more chronic course, worse consequences, lower personal and treatment control, lower illness coherence, and heavier emotional distress, and high numbers of psychological and culture-specific attributions. Fit indices of the three hypothesized path models (for physical and mental HRQoL and doctor-visit frequency, respectively supported the mediating role of illness perceptions. For example, the severity of alexithymia and non-gastrointestinal symptoms had significant negative effect on mental quality of life through both direct (standardized effect: −0.085 and −0.233 and indirect (standardized effect: −0.045 and −0.231 influence via subscales of consequences, emotional representation, and psychological and risk factor attributions.

This study investigated the association between gastrointestinal symptoms and a broad set of emotional and behavioral concerns in 95 children with high-functioning autism and IQ scores ≥ 80. Gastrointestinal symptoms were assessed via the Autism Treatment Network's Gastrointestinal Symptom Inventory, and data were gathered on autism symptom severity, adaptive behavior, and multiple internalizing and externalizing problems. The majority (61%) of children had at least one reported gastrointestinal symptom. Emotional and behavioral problems were also common but with a high degree of variability. Children with and without gastrointestinal problems did not differ in autism symptom severity, adaptive behavior, or total internalizing or externalizing problem scores. However, participants with gastrointestinal problems had significantly higher levels of affective problems. This finding is consistent with a small body of research noting a relationship between gastrointestinal problems, irritability, and mood problems in autism spectrum disorder. More research to identify the mechanisms underlying this relationship in autism spectrum disorder is warranted. Future research should include a medical assessment of gastrointestinal concerns, longitudinal design, and participants with a range of autism spectrum disorder severity in order to clarify the directionality of this relationship and to identify factors that may impact heterogeneity in the behavioral manifestation of gastrointestinal concerns. © The Author(s) 2013.

Role of Probiotics and Prebiotics in Functional Gastrointestinal Disorders in Children

2014-04-01

Full Text Available Introduction: Functional gastrointestinal disorders (FGID are non-fatal, unknown etiology disorders with absence of a structural or biochemical explanation and accounting for up to 50% of gastroenterology referrals. Infant regurgitation, rumination and cyclic vomiting constitute the vomiting disorders. Abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (IBS, functional abdominal pain, abdominal migraine and aerophagia. Disorders of defecation include: infant dyschezia, functional constipation, functional fecal retention and functional non-retentive fecal soiling. Current researches suggest a role of gut microbiota in pathogenesis of FGID and qualitative and quantitative alterations in the normal gut flora in some functional disorder such as IBS, chronic constipation and formula-fed infants which suffering colic or regurgitation  have been described. Probiotics are nonpathogenic microorganisms, when they are ingested, have positive effects on the host’s health. They influence intestinal physiology by different ways. Prebiotics are non-digestible carbohydrates which promote the growth and/or activity of probiotic bacteria. Evidences for the therapeutic or preventive effect of particular probiotic strains with or without prebiotics in FGID are available in many of articles. Results are encouraging in symptomatic alleviation and improvement in quality of life in IBS, functional constipation, functional abdominal pain,   infantile colic, aerophagia and infantile regurgitation.   Conclusion: Different probiotic strains have different effects, so selection of strains with specific health benefits is important. In general according to review of articles, although some of specific probiotic strains can provide a health benefit in these disorders, it seems, more high-quality and long-duration placebo-con-trolled trials are required.   Keywords: Functional gastrointestinal disorders, Probiotic.

Fast-food consumption has greatly increased in Taiwan. Frequent fast food intake is associated with both allergy and obesity. The aim of this study was to describe fast food habit changes, and to assess the relationship between fast food intake and the risk of functional gastrointestinal disorders (FGIDs) among Taiwanese adolescents. This analysis used data from the Nutrition and Health Survey in Taiwan (NAHSIT) of high school students conducted in 2011. A total of 2,042 adolescents (12-19 years) completed the questionnaire. The survey included the Rome III criteria for FGIDs, translated into Chinese for adolescents. Respondents with previously diagnosed chronic organic gastrointestinal diseases were excluded from the study. In total, 2,034 children were enrolled. 545 subjects (26.8%) had history of at least one FGID. 88.1% of the subjects reported fast foods consumption. A significantly higher prevalence of FGIDs was noted in adolescents with a history of fast foods consumption, compared with those reported not to have ingested fast foods in the past 30 days (27.6% vs 20.6%, p=0.024). An increased risk of FGIDs in children and adolescents was associated with fast food intake (OR 1.8, 95% CI: 1.78-1.83). FGIDs were common among Taiwanese adolescents. Fast-food consumption may contribute to a positive association with the development of functional gastrointestinal disorders. Lower fiber intake and more frozen desserts in the diet may be complicit in FGIDs. The findings have public health relevance in regard to the global increase in fast food consumption.

Use of neurotransmitter regulators in functional gastrointestinal disorders based on symptom analysis.

It has been a great challenge for gastroenterologists to cope with functional gastrointestinal disorders (FGIDs) in clinical practice due to the contemporary increase in stressful events. A growing body of evidence has shown that neuroregulators such as anti-anxiety agents and antidepressants function well on FGIDs, particularly in cases that are refractory to classical gastrointestinal (GI) medications. Among these central-acting agents, small individualized doses of tricyclic antidepressants and selective serotonin reuptake inhibitors are usually recommended as a complement to routine GI management. When these drugs are chosen to treat FGIDs, both their central effects and the modulation of peripheral neurotransmitters should be taken into consideration. In this article we recommend strategies for choosing drugs based on an analysis of psychosomatic GI symptoms. The variety and dosage of the neurotransmitter regulators are also discussed. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

The purpose of the study was to evaluate the prevalence of disordered gastrointestinal function following therapeutic irradiation. Gastrointestinal function was evaluated in 30 randomly selected patients who had received pelvic irradiation for treatment of carcinoma of the cervix between 1 and 6 years previously. Each patient underwent evaluations of (a) gastrointestinal symptoms (b) absorption of bile acid, vitamin B12, lactose and fat (c) gastrointestinal transit: gastric emptying, small intestinal transit and whole gut transit and (d) intestinal permeability. Results were compared with those obtained in 18 normal volunteers. Stool frequency was above the control range in five patients and had increased (p < 0.001) since radiotherapy treatment. Bile acid (p<0.001) vitamin B12(p<0.01) and lactose (p<0.01) absorption were less in the patients when compared with the control subjects. Bile acid adsorption was below the control range in 14 of the 30 patients. Dietary calcium intake was lower (p<0.05) in those patients with lactose malabsorption. Gastric emptying (p<0.01) and small intestinal transit (p<0.01) were more rapid in the patients. Both small intestinal (r=-0.39, p<0.05) and whole gut (r=-0.45) transit were inversely related to stool frequency. Either bowel frequency, bile acid adsorption, vitamin B12 absorption was outside the control range in 19 of the 30 patients. Abnormal gastrointestinal function is essentially an inevitable long-term sequel of pelvic irradiation. 41 refs., 4 figs., 3 tabs

Gastrointestinal function in the parasitized host

International Nuclear Information System (INIS)

Castro, G.A.

1981-01-01

Emphasis in this review is on (1) digestive-absorptive, secretory and smooth muscle functions altered by gastrointestinal (GI) parasites, (2) mechanisms by which parasites induce changes, and (3) the influence of parasite-induced alterations on the health of the host. Examples involving laboratory and domestic animals indicate that inflammation is an important factor in pathological alterations in epithelial and smooth muscle tissues throughout the alimentary canal. Observations on GI secretory activity reveal an influence of parasites on the host GI endocrine system. It is argued that assessments of the significance of parasite-induced changes on the host must be balanced with the adaptive potential and 'reserve capacity' of the GI system. In this regard host immunity should be considered a specific adaptation. Some tracer studies are mentioned marginally, such as the use of 14 C polyethylene glycol to estimate the direction of not fluid movement in the small intestine, and the use of 51 Cr to demonstrate the significantly faster intestinal transit in Trichinella spiralis infected animals

Full Text Available Functional gastrointestinal disorders (FGIDs are a common problem in children. These disorders in children are classified into the following categories according to the ROME III classification: Functional Dyspepsia, Irritable bowel syndrome (IBS, Abdominal Migraines, Childhood Functional abdominal pain (FAP, Childhood functional abdominal pain syndrome and functional constipation. FGIDs are diagnosed based on history and normal physical examination provided that there is no evidence of underlying disease such as anatomical abnormalities, infectious, inflammatory and malignancies. This group of poorly defined diseases represent a huge treatment challenge to the specialist, because, until now there is no therapy that has been effective in improving the symptoms. FGIDs also cause deep family problems as the disease interrupts their routine and positive response to treatment is rarely seen. On the other hand there is no objective document of the disease neither endoscopic, radiologic nor pathologic. Therapeutic strategies of FGIDs are: education and parent's assurance, detection and modifying physical and psychological stress, dietary intervention, pharmacological treatment, psychotherapy and other complementary medical treatments. Some foods may trigger the illness such as coffee, fatty foods and spicy foods, therefore they should be avoided. Lactose-free diet cannot improve symptoms of FGIDs, except in children with lactose intolerance. The beneficial effect of fiber supplement in children with FGIDs remains unknown but it has been useful in adults with IBS. Probiotics have potential efficacy in treating IBS but the efficacy in children with FGIDs remains uncertain and needs to be further studied. In patients with severe symptoms, pharmacological agents can be effective. These drugs include Antacids, Prokinetics, Anticholinergic, Tricyclic antidepressants (TCAS and Serotonergic agents (Agonists and anti agonists. Psychotherapy in FAP and IBS is

Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

The aim of this project is to investigate the effects of ionizing radiation (<10 Gy) on several parameters of gastrointestinal function: (a) regulatory peptides; (b) pancreatic and biliary secretions and (c) electrolyte and lipid transport using both gamma alone (cobalt-60) and a mixture of gamma/neutron ({gamma}/N Silene reactor) in two animal models, the rat and the pig. Preliminary data in rats following gamma irradiation (2-8 Gy) show that plasma nurotensin gastrin releasing peptide and substance P are increased in a dose dependent manner most markedly between two and four days after exposure. Intestinal brush border marker enzyme activities (sucrose and leucine amino-peptidase) were also reduced. Such differences were more marked and persisted longer after {gamma}/N irradiation (2-4 Gy: +Pb: {gamma}/:N =0.2). Following the latter type of irradiation (4 Gy) plasma cholesterol increased as well as the cholesterol/phospholipid ratio. Analysis of cholesterol distribution in lipoprotein actions revealed a large increase in cholesterol carried b High Density Lipoprotein-1 (HDL1). In the pig following either type of irradiation the volumes of both pancreatic and biliary secretions were reduced. Irradiation of pigs with either {gamma} (6 Gy) alone or {gamma}/N (6 Gy: {gamma}/N I :1) resulted in a marked decrease in both brush border (sucrase: leucine aminopeptidase) and basolateral (sodium ump` aden late cyclase) enzyme activities. Vasoactive intestinal peptide (VIP) stimulated adenylate cyclase was markedly attenuated and in addition specific VIP binding was modified as shown by a reduction in receptor affinity. The significance of the data will be discussed and the importance of a new therapeutic strategies or new biological markers of radiation-induced gastrointestinal dysfunction.

Full Text Available Background and Objective: The optimal treatment strategy for patients with gastric cancer is gastrectomy. Typically, nasogastric intubation is used after this type of surgery to feed patients; however, there seems to be no unanimity of opinion on this topic. Therefore, this study aimed to evaluate the effect of nasogastric intubation on gastrointestinal function after gastrectomy in gastric cancer patients. Materials and Method: This clinical trial was conducted on gastric cancer patients, admitted to the general ward of Imam Reza Hospital in Mashhad, Iran in 2015. In total, 68 patients were selected through randomized convenience sampling and divided into two intervention and control groups of 34 individuals. Nasogastric tube insertion was applied for the intervention group after the surgery. Patients of the study groups were fasted for three days after the surgery, which was followed by the removal of nasogastric tubes and initiation of oral feeding. Gastrointestinal function of all the participants was evaluated six hours after transferring to the ward up to seven days after the surgery on a daily basis using nausea and vomiting assessment tools and researcher-made questionnaire of gastrointestinal function. Data analysis was performed in SPSS version 16 using Fisher’s exact test, Chi-square, Mann-Whitney U, repeated measures ANOVA and paired t-test. Results: In this study, the severity of nausea and vomiting, the first time of passing gas and severity of flatulence Intensity were less observed in the control group, compared to the intervention group. Moreover, postoperative food tolerance was higher in the patients of the control group, compared to the other study group (P<0.05. Conclusion: According to the results of this study, nasogastric intubation can delay normal gastrointestinal function after gastrectomy. Therefore, it is not recommended to use this method after gastrectomy.

Current scintigraphic tests of gastrointestinal motor function provides relevant pathophysiologic information, but their clinical utility is controversial. Many scintigraphic methods are developed to investigate gastrointestinal motility from oral cavity to colon. These are esophageal transit scintigraphy, oropharyngeal transit study, gastric emptying test, small bowel transit time measurement, colon transit study and gastroesopahgeal reflux scintigraphy. Scintigraphy of gastrointestinal tract is the most physiologic and noninvasive method to evaluate gastrointestinal motility disorders. Stomach emptying test is regarded as a gold standard in motility study. Gastrointestinal transit scintigraphy also has a certain role in assessment of drug effect to GI motility and changes after theraphy of motility disorders. Scintigraphy provides noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. This article reviews the current procedures, indications, significance and guidelines for gastrointestinal motility measurements by scintigraphy.

We propose an intestine volume measurement method using a compound eye type endoscope. This method aims at assessment of the gastrointestinal function. Gastrointestinal diseases are mainly based on morphological abnormalities. However, gastrointestinal symptoms are sometimes apparent without visible abnormalities. Such diseases are called functional gastrointestinal disorder, for example, functional dyspepsia, and irritable bowel syndrome. One of the major factors for these diseases is abnormal gastrointestinal motility. For the diagnosis of the gastrointestinal tract, both aspects of organic and functional assessment is important. While endoscopic diagnosis is essential for assessment of organic abnormalities, three-dimensional information is required for assessment of the functional abnormalities. Thus, we proposed the three dimensional endoscope system using compound eye. In this study, we forces on the volume of gastrointestinal tract. The volume of the gastrointestinal tract is thought to related its function. In our system, we use a compound eye type endoscope system to obtain three-dimensional information of the tract. The volume can be calculated by integrating the slice data of the intestine tract shape using the obtained three-dimensional information. First, we evaluate the proposed method by known-shape tube. Then, we confirm that the proposed method can measure the tract volume using the tract simulated model. Our system can assess the wall of gastrointestinal tract directly in a three-dimensional manner. Our system can be used for examination of gastric morphological and functional abnormalities.

To promote the growth and development of premature infants, effective and tender care is required in neonatal intensive care units (NICUs). The purpose of this study was to test the potential effects of massage therapy on increasing physical growth and promoting gastrointestinal function in premature infants. Twenty subjects were divided into two groups in the NICU of one general hospital located in South Korea. The experimental group (n = 10) were given massage therapy and the control group (n = 10) received routine care. Massage therapy was performed twice daily for 14 days, for 15 minutes per session. In the physical growth, height and chest circumference were significantly increased in the experimental group. In assessing gastrointestinal function, frequency of pre-feed gastric residual was significantly decreased and numbers of bowel movements were significantly increased in the experimental group. This study showed massage therapy has the potential effects on increasing physical growth and gastrointestinal function in premature infants. The massage in the NICU might be utilized as a part of developmental care, but more research needs to be done. NICU nurses need to be trained in massage therapy techniques to provide more effective clinical care for premature infants. © The Author(s) 2015.

Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR. A history of upper gastrointestinal bleeding (Pupper gastrointestinal bleeding risk. In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding. The risk is higher in patients with previous upper gastrointestinal bleeding history and low serum albumin. Copyright © 2014 by the American Society of Nephrology.

Chey, William D

2013-05-01

Functional gastrointestinal disorders (FGIDs) are characterized by the presence of chronic or recurrent symptoms that are felt to originate from the gastrointestinal (GI) tract, which cannot be attributed to an identifiable structural or biochemical cause. Food is associated with symptom onset or exacerbation in a significant proportion of FGID patients. Despite this, the role of food in the pathogenesis of the FGIDs has remained poorly understood. For this reason, diet has largely played an adjunctive rather than a primary role in the management of FGID patients. In recent years, there has been a rapid expansion in our understanding of the role of food in GI function and sensation and how food relates to GI symptoms in FGID patients. In a series of evidence-based manuscripts produced by the Rome Foundation Working Group on the role of food in FGIDs, comprehensive reviews of the physiological changes associated with nutrient intake, and the respective roles of carbohydrates, fiber, protein, and fats are provided. The series concludes with a manuscript that provides guidance on proper clinical trial design when considering the role of food in FGIDs.

Postmortem changes have been previously studied in some terrestrial animal models, but no prior information is available on aquatic species. Gastrointestinal functionality was investigated in terms of indices, protein concentration, digestive enzyme activity, and scavenging activity, in an aquatic animal model, Nile tilapia, to assess the postmortem changes. Dead fish were floated indoors, and samples were collected within 48 h after death. Stomasomatic index decreased with postmortem time and correlated positively with protein, pepsin-specific activity, and stomach scavenging activity. Also intestosomatic index decreased significantly and correlated positively with protein, specific activity of trypsin, chymotrypsin, amylase, lipase, and intestinal scavenging activity. In their postmortem changes, the digestive enzymes exhibited earlier lipid degradation than carbohydrate or protein. The intestine changed more rapidly than the stomach. The findings suggest that the postmortem changes of gastrointestinal functionality can serve as primary data for the estimation of time of death of an aquatic animal. © 2016 American Academy of Forensic Sciences.

Functional gastrointestinal disorders (FGIDs) are defined as a variable combination of chronic or recurrent gastrointestinal symptoms not explained by structural or biochemical abnormalities. Infantile colic, gastroesophageal reflux, and constipation are the most common FGIDs that lead to referral to a pediatrician during the first 6 months of life and are often responsible for hospitalization, feeding changes, use of drugs, parental anxiety, and loss of parental working days with relevant social consequences. We performed a retrospective study on patients referred for recurrent abdominal pain from January 2002 trough December 2009 to our Pediatric Gastroenterology Outpatient Unit. The population studied was matched with healthy control without history of recurrent abdominal pain, enrolled among pediatricians practicing primary health care. History of infantile colic, regurgitation, and functional constipation was detected respectively in 26.41, 25.31, and 30.16% of children diagnosed with FGIDs compared to 11.34, 12.85, and 11.76% of healthy children. According to our data, children with a history of gastrointestinal infantile distress have a higher prevalence of FGIDs years later.

Gastrointestinal Headache; a Narrative Review

Directory of Open Access Journals (Sweden)

Majid T Noghani

2016-08-01

Full Text Available There are studies reporting primary headaches to be associated with gastrointestinal disorders, and some report resolution of headache following the treatment of the associated gastrointestinal disorder. Headache disorders are classified by The International Headache Society as primary or secondary; however, among the secondary headaches, those attributed to gastrointestinal disorders are not appreciated. Therefore, we aimed to review the literature to provide evidence for headaches, which originate from the gastrointestinal system. Gastrointestinal disorders that are reported to be associated with primary headaches include dyspepsia, gastro esophageal reflux disease (GERD, constipation, functional abdominal pain, inflammatory bowel syndrome (IBS, inflammatory bowel disorders (IBD, celiac disease, and helicobacter pylori (H. Pylori infection. Some studies have demonstrated remission or improvement of headache following the treatment of the accompanying gastrointestinal disorders. Hypotheses explaining this association are considered to be central sensitization and parasympathetic referred pain, serotonin pathways, autonomic nervous system dysfunction, systemic vasculopathy, and food allergy. Traditional Persian physicians, namely Ebn-e-Sina (Avicenna and Râzi (Rhazes believed in a type of headache originating from disorders of the stomach and named it as an individual entity, the "Participatory Headache of Gastric Origin". We suggest providing a unique diagnostic entity for headaches coexisting with any gastrointestinal abnormality that are improved or cured along with the treatment of the gastrointestinal disorder.

Functional gastrointestinal disorders (FGDs) are recognized sequelae of infectious gastroenteritis (IGE). Within the active duty military population, a group with known high IGE rates, the population-based incidence, risk factors, and attributable burden of care referable to FGD after IGE are poorly defined. Using electronic medical encounter data (1999-2007) on active duty US military, a matched, case-control study describing the epidemiology and risk determinants of FGD (irritable bowel syndrome (IBS), functional constipation (FC), functional diarrhea (FD), dyspepsia (D)) was conducted. Incidence rates and duration of FGD-related medical care were estimated, and conditional logistic regression was utilized to evaluate FGD risk after IGE. A total of 31,866 cases of FGD identified were distributed as follows: FC 55% (n=17,538), D 21.2% (n=6,750), FD 2.1% (n=674), IBS 28.5% (n=9,091). Previous IGE episodes were distributed as follows: specific bacterial pathogen (n=65, 1.2%), bacterial, with no pathogen specified (n=2155, 38.9%), protozoal (n=38, 0.7%), viral (n=3431, 61.9%). A significant association between IGE and all FGD (odds ratio (OR) 2.64; Phigh risk for IGE. When considering effective countermeasures and mitigation strategies, attention directed toward prevention as well as the acute and chronic sequelae of these infections is needed.

The updated Rome III Classification of paediatric functional gastrointestinal disorders (FGIDs) associated with abdominal pain comprises: functional dyspepsia (FD), irritable bowel syndrome (IBS), abdominal migraine, functional abdominal pain (FAP), functional abdominal pain syndrome (FAPS). To assess the value of the Rome criteria in identifying FGIDs in children with chronic abdominal pain. The study group consisted of 439 consecutive paediatric patients (192 boys and 247 girls) aged 4-18 years (mean age was 11.95 +/- 3.89 years) referred to the Paediatric Gastroenterology Department at Medical University of Lodz from January 2008 to June 2009 for evaluation of abdominal pain of at least 2 months' duration. After exclusion of organic disease children suspected of functional chronic abdominal pain were categorized with the use of Rome III criteria of FGIDs associated with abdominal pain (H2a-H2d1) and the Questionnaire on Paediatric Gastrointestinal Symptoms (with the permission of doctor L. S. Walker). The patients with known nonabdominal organic disease, chronic illness or handicap were excluded. In 161 patients (36.58%) organic etiology was confirmed. Of the 278 children (63.42%) with functional chronic abdominal pain, 228 (82.02%) met the Rome III criteria for FGIDs associated with abdominal pain (FD, 15.5%; IBS, 21.6%; abdominal migraine, 5%; FAP 24.5%; FAPS, 15.9%). Fifty cases (17.98%) did not fulfill the criteria for subtypes of abdominal pain-related FGIDs--mainly due to different as defined by Rome III criteria (at least once per week) frequency of symptom presentation. (1) In the authors'investigations FGIDs was the most frequent cause of chronic abdominal pain in children. (2) The significant number of children with nonclassified FGIDs implies the need to modify the diagnostic criteria of Rome III classification concerning the prevalence of symptoms.

Kelber, Olaf; Bauer, Rudolf; Kubelka, Wolfgang

2017-01-01

Phytotherapy is an important therapeutic option in functional gastrointestinal diseases (FGID). It has a large tradition, with different approaches in different regions of the world, some of which have made their way into modern evidence-based medicine (EBM). Taking into account the number of herbs in use, and also the cumulated scientific evidence on them, FGID are possibly the most important indication in phytotherapy. This does not only apply for European phytotherapy, but also for other regions, such as Asia. Within European phytotherapy, herbs active in FGID are usually classified according to their main active constituents and their activities. Typically, the herbs used in FGID are grouped into amara, aromatica, amara aromatica combining both properties, herbs stimulating gastric secretion, herbs containing spasmolytic and carminative essential oils or spasmolytic alkaloids, mucilaginosa soothing the mucosa, and flavonoid containing drugs with anti-inflammatory properties. In phytotherapy, different plants are frequently combined to maximize effectiveness and specificity of action. Very potent combination products can be developed when the mechanisms of action of the combination partners are complementary. This approach can be demonstrated by the example of STW 5. For this herbal combination product, therapeutic efficacy in FGID has been clinically proven according to the highest standards of EBM. This example also underlines that modern rational phytotherapy is definitely part of modern EBM. Key Messages: FGID is one of the most important indications in phytotherapy and rationally combined herbal preparations are established evidence-based therapeutic options. © 2018 The Author(s) Published by S.

Many pediatric patients use complementary and alternative medicine, especially when facing a chronic illness for which treatment options are limited. So far, research on the use of complementary and alternative medicine in patients with functional gastrointestinal disease has been scarce. This study was designed to assess complementary and alternative medicine use in children with different gastrointestinal diseases, including functional disorders, to determine which factors predicted complementary and alternative medicine use and to assess the willingness of parents to participate in future studies on complementary and alternative medicine efficacy and safety. The prevalence of complementary and alternative medicine use was assessed by using a questionnaire for 749 children visiting pediatric gastroenterology clinics of 9 hospitals in the Netherlands. The questionnaire consisted of 35 questions on the child's gastrointestinal disease, medication use, health status, past and future complementary and alternative medicine use, reasons for its use, and the necessity of complementary and alternative medicine research. In this study population, the frequency of complementary and alternative medicine use was 37.6%. A total of 60.3% of this group had used complementary and alternative medicine specifically for their gastrointestinal disease. This specific complementary and alternative medicine use was higher in patients with functional disorders than organic disorders (25.3% vs 17.2%). Adverse effects of allopathic medication, school absenteeism, age effect of conventional treatment were predictors of specific complementary and alternative medicine use. Almost all (93%) of the parents considered it important that pediatricians initiate complementary and alternative medicine research, and 51% of parents were willing to participate in future complementary and alternative medicine trials. Almost 40% of parents of pediatric gastroenterology patients are turning to

Sleep deprivation and impaired sleep quality have been associated with poor health outcomes. Many patients experience sleep disturbances, which can increase the risk of medical conditions such as hypertension, obesity, stroke, and heart disease as well as increase overall mortality. Recent studies have suggested that there is a strong association between sleep disturbances and gastrointestinal diseases. Proinflammatory cytokines, such as tumor necrosis factor, interleukin-1, and interleukin-6, have been associated with sleep dysfunction. Alterations in these cytokines have been seen in certain gastrointestinal diseases, such as gastroesophageal reflux disease, inflammatory bowel disease, liver disorders, and colorectal cancer. It is important for gastroenterologists to be aware of the relationship between sleep disorders and gastrointestinal illnesses to ensure good care for patients. This article reviews the current research on the interplay between sleep disorders, immune function, and gastrointestinal diseases.

2009-01-01

Functional gastrointestinal disorders (FGIDs) are a highly prevalent group of heterogeneous disorders whose diagnostic criteria are symptom based in the absence of a demonstrable structural or biochemical abnormality. Chronic abdominal pain or discomfort is a defining characteristic of these disorders and a proportion of patients may display heightened pain sensitivity to experimental visceral stimulation, termed visceral pain hypersensitivity (VPH). We examined the most recent literature in order to concisely review the evidence for some of the most important recent advances in the putative mechanisms concerned in the pathophysiology of VPH. VPH may occur due to anomalies at any level of the visceral nociceptive neuraxis. Important peripheral and central mechanisms of sensitization that have been postulated include a wide range of ion channels, neurotransmitter receptors and trophic factors. Data from functional brain imaging studies have also provided evidence for aberrant central pain processing in cortical and subcortical regions. In addition, descending modulation of visceral nociceptive pathways by the autonomic nervous system, hypothalamo-pituitary-adrenal axis and psychological factors have all been implicated in the generation of VPH. Particular areas of controversy have included the development of efficacious treatment of VPH. Therapies have been slow to emerge, mainly due to concerns regarding safety. The burgeoning field of genome wide association studies may provide further evidence for the pleiotropic genetic basis of VPH development. Tangible progress will only be made in the treatment of VPH when we begin to individually characterize patients with FGIDs based on their clinical phenotype, genetics and visceral nociceptive physiology.

The purpose of this study was to gain experience with and validate the Heidelberg pH-telemetric methodology in order to determine if the pH-telemetric methodology would be a useful noninvasive measure of gastrointestinal transit time for future ground-based and in-flight drug evaluation studies. The Heidelberg pH metering system is a noninvasive, nonradioactive telemetric system that, following oral ingestion, continuously measures intraluminal pH of the stomach, duodenum, small bowel, ileocecal junction, and large bowel. Gastrointestinal motility profiles were obtained in normal volunteers using the lactulose breath-hydrogen and Heidelberg pH metering techniques. All profiles were obtained in the morning after an overnight fast. Heidelberg pH profiles were obtained in the fasting and fed states; lactulose breath-hydrogen profiles were obtained after a standard breakfast. Mouth-to-cecum transit time was measured as the interval from administration of lactulose (30 ml; 20 g) to a sustained increase in breath-hydrogen of 10 ppm or more. Gastric emptying time was measured as the interval from the administration of the Heidelberg capsule to a sustained increase in pH of three units or more.

Wnt Signalling in Gastrointestinal Epithelial Stem Cells

Directory of Open Access Journals (Sweden)

Dustin J. Flanagan

2018-03-01

Full Text Available Wnt signalling regulates several cellular functions including proliferation, differentiation, apoptosis and migration, and is critical for embryonic development. Stem cells are defined by their ability for self-renewal and the ability to be able to give rise to differentiated progeny. Consequently, they are essential for the homeostasis of many organs including the gastrointestinal tract. This review will describe the huge advances in our understanding of how stem cell functions in the gastrointestinal tract are regulated by Wnt signalling, including how deregulated Wnt signalling can hijack these functions to transform cells and lead to cancer.

Gastrointestinal Epithelial Organoid Cultures from Postsurgical Tissues.

An organoid is a cellular structure three-dimensionally (3D) cultured from self-organizing stem cells in vitro, which has a cell population, architectures, and organ specific functions like the originating organs. Recent advances in the 3D culture of isolated intestinal crypts or gastric glands have enabled the generation of human gastrointestinal epithelial organoids. Gastrointestinal organoids recapitulate the human in vivo physiology because of all the intestinal epithelial cell types that differentiated and proliferated from tissue resident stem cells. Thus far, gastrointestinal organoids have been extensively used for generating gastrointestinal disease models. This protocol describes the method of isolating a gland or crypt using stomach or colon tissue after surgery and establishing them into gastroids or colonoids.

2018-03-01

Central neuromodulators (antidepressants, antipsychotics, and other central nervous system-targeted medications) are increasingly used for treatment of functional gastrointestinal disorders (FGIDs), now recognized as disorders of gut-brain interaction. However, the available evidence and guidance for the use of central neuromodulators in these conditions is scanty and incomplete. In this Rome Foundation Working Team report, a multidisciplinary team summarized available research evidence and clinical experience to provide guidance and treatment recommendations. The working team summarized the literature on the pharmacology of central neuromodulators and their effects on gastrointestinal sensorimotor function and conducted an evidence-based review on their use for treating FGID syndromes. Because of the paucity of data for FGIDs, we included data for non-gastrointestinal painful disorders and specific symptoms of pain, nausea, and vomiting. This information was combined into a final document comprising a synthesis of available evidence and recommendations for clinical use guided by the research and clinical experience of the experts on the committee. The evidence-based review on neuromodulators in FGID, restricted by the limited available controlled trials, was integrated with open-label studies and case series, along with the experience of experts to create recommendations using a consensus (Delphi) approach. Due to the diversity of conditions and complexity of treatment options, specific recommendations were generated for different FGIDs. However, some general recommendations include: (1) low to modest dosages of tricyclic antidepressants provide the most convincing evidence of benefit for treating chronic gastrointestinal pain and painful FGIDs and serotonin noradrenergic reuptake inhibitors can also be recommended, though further studies are needed; (2) augmentation, that is, adding a second treatment (adding quetiapine, aripiprazole, buspirone α2δ ligand

Supplementation strategies for gastrointestinal distress in endurance athletes

Full Text Available The prevalence of gastrointestinal symptoms in the endurance athlete is about 25% to 70%. Even though it is recognized that the etiology of exercise-induced gastrointestinal distress is multifactorial, blood flow redistribution during physical activity and therefore gastrointestinal ischemia is often acknowledged as the main pathophysiology mechanism for the onset of symptoms. This review will provide an overview to the recent research on gastrointestinal function during strenuous exercise. In addition, we consider different nutritional interventions that could be evaluated for preventive or treatment interventions founding that ever though there is some research in the area, the scientific evidence does not support its use in athlete population.

Gastrointestinal function in chronic radiation enteritis -effects of loperamide-N-oxide

International Nuclear Information System (INIS)

Yeoh, E.K.; Horowitz, M.; Russo, A.; Muecke, T.; Chatterton, B.E.; Robb, T.

1993-01-01

The effects of loperamide-N-oxide, a new peripheral opiate agonist precursor, on gastrointestinal function were evaluated in 18 patients with diarrhoea caused by radiation enteritis. Each patient was given loperamide-N-oxide and placebo for 14 days, separated by a washout period of 14 days. Gastrointestinal symptoms; absorption of bile acid, vitamin B12, lactose, and fat; gastric emptying; small intestinal and whole gut transit; and intestinal permeability were measured during placebo and loperamide-N-oxide phases. Data were compared with those obtained in 18 normal subjects. In the patient, in addition to an increased frequency of bowel actions there was reduced bile acid absorption, higher prevalence of lactose malabsorption associated with a reduced dietary intake of dairy products and faster small intestinal and whole gut transit when compared with the normal subjects. There was no significant difference in gastric emptying between the two groups. Treatment with loperamide-N-oxide was associated with a reduced frequency of bowel actions, slower small intestinal and total gut transit, more rapid gastric emptying improved absorption of bile acid and increased permeability to 51 Cr EDTA. These observations indicate that: (1) diarrhoea caused by chronic radiation enteritis is associated with more rapid intestinal transit and a high prevalence of bile acid and lactose malabsorption, and (2) loperamide-N-oxide slows small intestinal transit, increases bile acid absorption, and is effective in the treatment of diarrhoea associated with chronic radiation enteritis.

Multiple system atrophy (MSA) can clinically be divided into the cerebellar (MSA-C) and the parkinsonian (MSA-P) variant. However, till now, it is unknown whether autonomic dysfunction in these two entities differs regarding severity and profile. We compared the pattern of autonomic dysfunction in 12 patients with MSA-C and 26 with MSA-P in comparison with 27 age- and sex-matched healthy controls using a standard battery of autonomic function tests and a structured anamnesis of the autonomic nervous system. MSA-P patients complained significantly more often about the symptoms of autonomic dysfunctions than MSA-C patients, especially regarding vasomotor, secretomotor, and gastrointestinal subsystems. However, regarding cardiovascular, sudomotor pupil, urogenital, and sleep subsystems, there were no significant quantitative or qualitative differences as analyzed by autonomic anamnesis and testing. Our results suggest that there are only minor differences in the pattern of autonomic dysfunction between the two clinical MSA phenotypes. (c) 2007 Movement Disorder Society.

To investigate the magnitude and determinants of the placebo response in studies with pediatric abdominal pain-related functional gastrointestinal disorders. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL were searched for systematic reviews and randomized placebo-controlled trials concerning children 4-18 years of age with an abdominal pain-related functional gastrointestinal disorder. The primary outcome was the pooled proportion of subjects assigned to placebo with improvement as defined by the authors. The effect of trial characteristics on the magnitude of the placebo response was investigated using univariate meta-regression analysis. Twenty-one trials were identified. The pooled proportion of subjects with improvement was 41% (95% CI, 34%-49%; 17 studies) and with no pain was 17% (95% CI, 8%-32%; 7 studies). The pooled standardized mean difference on the Faces Pain Scales compared with baseline was -0.73 (95% CI, -1.04 to -0.42; 8 studies). There was significant heterogeneity across studies with respect to both outcomes. Lower dosing frequency (P = .04), positive study (P = .03), longer duration of treatment (P pain. Response on Faces Pain Scales was greater in studies conducted in the Middle East (P = .002), in studies that did not report the randomization schedule (P = .02), and in studies with a higher percentage of females (P = .04). Approximately 41% of children with abdominal pain-related functional gastrointestinal disorders improve on placebo. Several trial characteristics are correlated significantly with the proportion of patients with no pain on placebo and with the magnitude of the placebo response on Faces Pain Scales. These data could be valuable for the design of future studies. Copyright © 2016 Elsevier Inc. All rights reserved.

Gregersen, Hans; Liao, Donghua; Drewes, Anne Mohr; Drewes, Asbjørn Mohr; Zhao, Jingbo

2016-02-01

Symptoms related to functional and sensory abnormalities are frequently encountered in patients with diabetes mellitus. Most symptoms are associated with impaired gastric and intestinal function. In this review, we discuss basic concepts of sensory-motor dysfunction and how they relate to clinical findings and gastrointestinal abnormalities that are commonly seen in diabetes. In addition, we review techniques that are available for investigating the autonomic nervous system, neuroimaging and neurophysiology of sensory-motor function. Such technological advances, while not readily available in the clinical setting, may facilitate stratification and individualization of therapy in diabetic patients in the future. Unraveling the structural, mechanical, and sensory remodeling in diabetes disease is based on a multidisciplinary approach that can bridge the knowledge from a variety of scientific disciplines. The final goal is to increase the understanding of the damage to GI structures and to sensory processing of symptoms, in order to assist clinicians with developing an optimal mechanics based treatment.

Enteroendocrine cells: a site of 'taste' in gastrointestinal chemosensing.

Science.gov (United States)

Sternini, Catia; Anselmi, Laura; Rozengurt, Enrique

2008-02-01

This review discusses the role of enteroendocrine cells of the gastrointestinal tract as chemoreceptors that sense lumen contents and induce changes in gastrointestinal function and food intake through the release of signaling substances acting on a variety of targets locally or at a distance. Recent evidence supports the concept that chemosensing in the gut involves G protein-coupled receptors and effectors that are known to mediate gustatory signals in the oral cavity. These include sweet-taste and bitter-taste receptors, and their associated G proteins, which are expressed in the gastrointestinal mucosa, including selected populations of enteroendocrine cells. In addition, taste receptor agonists elicit a secretory response in enteroendocrine cells in vitro and in animals in vivo, and induce neuronal activation. Taste-signaling molecules expressed in the gastrointestinal mucosa might participate in the functional detection of nutrients and harmful substances in the lumen and prepare the gut to absorb them or initiate a protective response. They might also participate in the control of food intake through the activation of gut-brain neural pathways. These findings provide a new dimension to unraveling the regulatory circuits initiated by luminal contents of the gastrointestinal tract.

Full Text Available Abstract Background A Giardia outbreak was associated with development of post-infectious functional gastrointestinal disorders (PI-FGID and chronic fatigue syndrome (PI-CFS. Markers of immune dysfunction have given conflicting results in CFS and FGID patient populations. The aim of this study was to evaluate a wide selection of markers of immune dysfunction in these two co-occurring post-infectious syndromes. Methods 48 patients, reporting chronic fatigue in a questionnaire study, were clinically evaluated five years after the outbreak and grouped according to Fukuda criteria for CFS (n=19 and idiopathic chronic fatigue (n=5 and Rome II criteria for FGIDs (n=54. 22 Giardia exposed non-fatigued individuals and 10 healthy unexposed individuals were recruited as controls. Peripheral blood lymphocyte subsets were analyzed by flow cytometry. Results In peripheral blood we found significantly higher CD8 T-cell levels in PI-FGID, and significantly lower NK-cell levels in PI-CFS patients. Severity of abdominal and fatigue symptoms correlated negatively with NK-cell levels. A tendency towards lower T-cell CD26 expression in FGID was seen. Conclusion Patients with PI-CFS and/or PI-FGID 5 years after Giardia lamblia infection showed alterations in NK-cell and CD8-cell populations suggesting a possible immunological abnormality in these conditions. We found no significant changes in other markers examined in this well-defined group of PI-CFS and PI-FGID elicited by a gastrointestinal infection. Controlling for co-morbid conditions is important in evaluation of CFS-biomarkers.

To determine the prevalence, pattern, and predisposing factors of abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs) in adolescent Nigerians. A cross-sectional study was conducted in 2 states in the southern part of Nigeria in June 2014. Adolescents of age 10 to 18 years were recruited from 11 secondary schools using a stratified random sampling technique. A validated self-administered questionnaire on Rome III criteria for diagnosing AP-FGIDs and its determinants were filled by the participants in a classroom setting. A total of 874 participants filled the questionnaire. Of this, 818 (93.4%) filled it properly and were included in the final analysis. The mean age of the participants was 14.6 ± 2.0 years with 409 (50.0%) being boys. AP-FGIDs were present in 81 (9.9%) participants. Forty six (5.6%) of the study participants had irritable bowel syndrome (IBS), 21 (2.6%) functional abdominal pain, 15 (1.8%) abdominal migraine while 3 (0.4%) had functional dyspepsia. The difference in AP-FGIDs between adolescents residing in rural and urban areas was not statistically significant (P = 0.22). Intestinal and extra-intestinal symptoms occurred more frequently in those with AP-FGIDs. Nausea was the only symptom independently associated with AP-FGIDs (p = 0.015). Multiple regression analysis showed no significant association between stressful life events and AP-FGIDs. AP-FGIDs are a significant health problem in Nigerian adolescents. In addition to the intestinal symptoms, most of the affected children and others also had extraintestinal symptoms. None of the stressful life events evaluated was significantly associated with FGIDs.

Population-based studies of the prevalence of all functional gastrointestinal disorders (FGID) using the Rome II criteria are lacking. It is also not certain whether subjects who meet the Rome II criteria for an FGID are different in terms of demographic and psychological characteristics from those subjects meeting exclusively the more restrictive Rome I criteria. To determine whether using the more restrictive Rome I criteria would result in a more biologically determined group of FGID than when the Rome II is applied. Subjects included individuals aged 18 years and older (n = 1,225) from the Penrith population who were initially surveyed with the Penrith District Health Survey in 1997. Subjects were sent a self-report questionnaire that contained items on gastrointestinal symptoms applying the Rome II criteria. Subjects were also assessed on psychological and personality factors and on physical and mental functioning. A total of 36.1% (n = 275) of respondents was diagnosed with an FGID according to Rome II criteria. The five most prevalent FGID were functional heartburn (10.4%), irritable bowel syndrome (8.9%), functional incontinence (7.6%), proctalgia fugax (6.5%) and functional chest pain (5.1%). Subjects meeting Rome II only criteria for FGID scored significantly higher on measures of psychological caseness and emotionality than Rome I only subjects, and these were independently associated with meeting Rome I only versus Rome II only criteria for FGID. The Rome II criteria FGID are common and do not appear to identify a vastly different group of FGID sufferers compared with the earlier Rome I criteria.

Evidence Suggesting that the Buccal and Zygomatic Branches of the Facial Nerve May Contain Parasympathetic Secretomotor Fibers to the Parotid Gland by Means of Communications from the Auriculotemporal Nerve.

The auriculotemporal nerve is one of the peripheral nerves that communicates with the facial nerve. However, the function of these communications is poorly understood. Details of how these communications form and connect with each other are still unclear. In addition, a reliable anatomical landmark for locating these communications during surgery has not been sufficiently described. Microdissection was performed on 20 lateral hemifaces of 10 soft-embalmed cadavers to investigate facial-auriculotemporal nerve communications with emphasis on determining their function. The auriculotemporal nerve was identified in the retromandibular space and traced towards its terminations. The communicating branches were followed and the anatomical relationships to surrounding structures observed. The auriculotemporal nerve is suspended above the maxillary artery in the dense retromandibular fascia behind the mandibular ramus. It forms a knot and fans out, providing multiple branches in all directions in the sagittal plane. Inferiorly, it connects the maxillary periarterial plexus, while minute branches supply the temporomandibular joint anteriorly. The larger branches mainly communicate with the branches of the temporofacial division of the facial nerve, and the auricular branches enter the fascia of the auricular cartilage posteriorly. The temporal branches and occasionally the zygomatic branches arise superiorly to distribute within the temporoparietal fascia. The auriculotemporal nerve forms the parotid retromandibular plexus through two types of communication. It sends one to three branches to join the zygomatic and buccal branches of the facial nerve at the branching area of the temporofacial division. It also communicates with the periarterial plexus of the superficial temporal and maxillary arteries. This plexus continues anteriorly along the branches of the facial nerve and the periarterial plexus of the transverse facial artery as the parotid periductal autonomic plexus

Roles and Regulation of Gastrointestinal Eosinophils in Immunity and Disease

Science.gov (United States)

Jung, YunJae; Rothenberg, Marc E.

2014-01-01

Eosinophils have been considered to be destructive end-stage effector cells that have a role in parasitic infections and allergy reactions by the release of their granule-derived cytotoxic proteins. However, an increasing number of experimental observations indicate that eosinophils also are multifunctional leukocytes involved in diverse inflammatory and physiologic immune responses. Under homeostatic conditions, eosinophils are particularly abundant in the lamina propria of the gastrointestinal tract where their involvement in various biological processes within the gastrointestinal tract has been posited. In this review, we summarize the molecular steps involved in eosinophil development and describe eosinophil trafficking to the gastrointestinal tract. We synthesize the current findings on the phenotypic and functional properties of gastrointestinal eosinophils and the accumulating evidence that they have a contributory role in gastrointestinal disorders, with a focus on primary eosinophilic gastrointestinal disorders. Finally, we discuss the potential role of eosinophils as modulators of the intestinal immune system. PMID:25049430

A review is presented of the design of radiolabelled test meals for the evaluation of gastrointestinal function, including oesophageal transit, gastro-oesophageal reflux, gastric emptying, enterogastric reflux and transit through the whole bowel. Descriptions of different systems are presented, together with validations of the procedures used. Published methods for assessment of oesophageal transit show a marked degree of consistency, whereas gastric emptying studies employ a wide range of both liquid and solid test meals. Recommendations are made concerning the optimal system for investigation of each part of the gastrointestinal tract, but whichever system is adopted, it is important to employ some validation procedures, and to establish normal ranges in the population under study.

It is unknown whether children with functional gastrointestinal (GI) disorders identify specific foods that exacerbate their GI symptoms. The objectives of this study were to determine the perceived role of food on GI symptoms and to determine the impact of food-induced symptoms on quality of life (QOL) in children with functional GI disorders. Between August and November 2010, 25 children ages 11 to 17 years old with functional GI disorders and a parent completed a food symptom association questionnaire and validated questionnaires assessing FGID symptoms and QOL. In addition, children completed a 24-hour food recall, participated in focus groups to identify problematic foods and any coping strategies, and discussed how their QOL was affected. Statistical analyses were conducted using χ2, t test, Mann-Whitney U test, Wilcoxon signed rank, and Spearman's ρ. Children identified a median of 11 (range=2 to 25) foods as exacerbating a GI symptom, with the most commonly identified foods being spicy foods, cow's milk, and pizza. Several coping strategies were identified, including consuming smaller portions, modifying foods, and avoiding a median of 8 (range=1 to 20) foods. Children reported that food-induced symptoms interfered with school performance, sports, and social activities. Although the parent's assessment of their child's QOL negatively correlated with the number of perceived symptom-inducing foods in their child, this relationship was not found in the children. Findings suggest that specific foods are perceived to exacerbate GI symptoms in children with functional GI disorders. In addition, despite use of several coping strategies, food-induced symptoms can adversely impact children's QOL in several important areas. Copyright © 2014 Academy of Nutrition and Dietetics.

Non-pharmacological management of abdominal pain-related functional gastrointestinal disorders in children.

Science.gov (United States)

Paul, Siba Prosad; Basude, Dharamveer

2016-11-01

Abdominal pain-related functional gastrointestinal disorder (AP-FGID) comprises of 4 main conditions: functional dyspepsia, irritable bowel syndrome, abdominal migraine and functional abdominal pain. AP-FGIDs are diagnosed clinically based on the Rome IV criteria for FGIDs of childhood. There is limited evidence for pharmacological therapies. This review article discusses nonpharmacological management of AP-FGID based on the current literature including systematic reviews, randomized controlled trials, cohort and case control studies. We aim to provide a comprehensive overview on the available evidence for the pediatricians and pediatric gastroenterologists involved in managing children with AP-FGID. Managing AP-FGIDs can be challenging. This should follow a stepwise approach with focused history, identification of "red flag" signs and symptoms, physical examination and investigations done following initial consultation. Family needs explaining that there is nothing seriously wrong with the child's abdomen. This explanation and reassurance can achieve symptom control in large number of cases. Non-pharmacological interventions are delivered through lifestyle and dietary changes and bio-psychosocial therapies. Dietary interventions vary depending on the type of AP-FGID. Bio-psychosocial therapies such as hypnotherapy, cognitive behavioral therapy and yoga aim at stress reduction. There is increasing evidence for use of non-pharmacological interventions in children with APFGID.

Functional gastrointestinal disorders (FGIDs) entail several distinct conditions that collectively account for a sizeable proportion of patients complaining of abdominal pain. Physicians' awareness is fundamental to avoid unnecessary evaluations and to alleviate stress-related problems. This study aimed to assess the relative frequencies of FGIDs and related categories in a selected Iranian population. We conducted this cross-sectional study in a gastroenterology clinic of a tertiary care pediatric hospital in Iran. Children and adolescents between the age of 4 and 18 years referred to the clinic from October 2011 to February 2013 were enrolled if they were diagnosed with FGID according to the Rome III criteria. A structured questionnaire was used to collect data on demographic characteristics, pain location, duration and frequency, associated symptoms, and pertinent family history. We used descriptive analyses to show mean (±SD) and relative frequencies of categories of FGIDs. We diagnosed 183 (114 female) with FGIDs out of 1307 children and adolescents who were visited in the clinic. There was history of psychiatric disorders in 42 (22.9%) participants, and migraine headaches and gastrointestinal disorders were at least in one of the parents in 21 (11.5%) and 64 (34.9%) participants, respectively. We defined 84 (46%) patients under Irritable Bowel Syndrome (IBS) category, 38 (21%) under Abdominal Migraine, 26 (14%) under Functional Abdominal Pain, 21 (11%) under Functional Dyspepsia, and 7 (4%) under Functional Abdominal Pain Syndrome. Seven children (4%) had no defining feature for FGID categories and therefore labeled as unclassified. FGID was a prevalent diagnosis among children and adolescents with abdominal pain. IBS was the largest category. Only a minority were unclassifiable under the Rome III criteria, indicating improved differentiation characteristics of Rome III criteria compared to the Rome II version.

Full Text Available Functional gastrointestinal disorders (FGID, including irritable bowel syndrome, functional dyspepsia and functional abdominal pain, are common in adolescents and are associated with substantially decreased quality of life. Cognitive behavior therapy for children and adolescents with FGID is one of few treatments that have shown effect, but treatment access is limited. In adults with irritable bowel syndrome, exposure-based internet-delivered CBT (ICBT leads to reduced symptoms and increased quality of life, but studies in children are lacking. This open pilot aimed to evaluate feasibility and the potential efficacy of an exposure-based ICBT-program for adolescents with pain-predominant FGID. Twenty-nine adolescents (age 13–17, with FGID were included. The ICBT-program lasted for 8 weeks with weekly online therapist support. The protocol for adolescents included exposure to abdominal symptoms, while the protocol for parents aimed at increasing parents' attention to adolescent healthy behaviors. Assessment points were baseline, post-treatment and 6-month follow-up. The primary outcome was the Gastrointestinal Symptoms Rating Scale-IBS (GSRS-IBS. Effect sizes were calculated using Cohen's d in an intent to treat analysis. GSRS-IBS improved significantly from baseline to post-treatment (mean difference 6.48; 95% CI [2.37–10.58] and to follow-up (mean difference 7.82; 95% CI [3.43–12.21], corresponding to moderate effect sizes (within-group Cohen's d = 0.50; 95% CI [0.16–0.84] and d = 0.63; 95% CI [0.24–1.02], respectively. Treatment adherence was high with 22 of 29 (76% adolescents completing the entire treatment period. High adherence indicates acceptability of format and content, while symptomatic improvement suggests potential efficacy for this ICBT intervention in adolescents with FGID.

Sleep disorders have become a global issue, and discovering their causes and consequences are the focus of many research endeavors. An estimated 70 million Americans suffer from some form of sleep disorder. Certain sleep disorders have been shown to cause neurocognitive impairment such as decreased cognitive ability, slower response times and performance detriments. Recent research suggests that individuals with sleep abnormalities are also at greater risk of serious adverse health, economic consequences, and most importantly increased all-cause mortality. Several research studies support the associations among sleep, immune function and inflammation. Here, we review the current research linking sleep, immune function, and gastrointestinal diseases and discuss the interdependent relationship between sleep and these gastrointestinal disorders. Different physiologic processes including immune system and inflammatory cytokines help regulate the sleep. The inflammatory cytokines such as tumor necrosis factor, interleukin-1 (IL-1), and IL-6 have been shown to be a significant contributor of sleep disturbances. On the other hand, sleep disturbances such as sleep deprivation have been shown to up regulate these inflammatory cytokines. Alterations in these cytokine levels have been demonstrated in certain gastrointestinal diseases such as inflammatory bowel disease, gastro-esophageal reflux, liver disorders and colorectal cancer. In turn, abnormal sleep brought on by these diseases is shown to contribute to the severity of these same gastrointestinal diseases. Knowledge of these relationships will allow gastroenterologists a great opportunity to enhance the care of their patients.

Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

Gastrointestinal hormones are peptides released from neuroendocrine cells in the digestive tract. More than 30 hormone genes are currently known to be expressed in the gut, which makes it the largest hormone-producing organ in the body. Modern biology makes it feasible to conceive the hormones...... as a blood-borne hormone, a neurotransmitter, a local growth factor or a fertility factor. The targets of gastrointestinal hormones are specific G-protein-coupled receptors that are expressed in the cell membranes also outside the digestive tract. Thus, gut hormones not only regulate digestive functions...

1986-10-01

In the developed countries gastrointestinal tuberculosis is no longer common in clinical practice. In this setting the importance of the condition lies in the vagaries of its presentation and the fact that it is eminently treatable, usually by a combination of chemotherapy and surgery. The clinical features and complications of gastrointestinal tuberculosis are highlighted by the seven cases which we report. Diagnosis and treatment of this condition is discussed and attention is drawn to the importance of case notification. Clinicians should bear in mind the diagnosis of gastrointestinal tuberculosis when dealing with any patient with non-specific abdominal symptoms.

Full Text Available Aims. The frequency of functional gastrointestinal disorders (FGIDs in the general population of Mexico is unknown. Methods. To determine the prevalence of FGIDs, associated depression, and health care utilization, a population-based sampling strategy was used to select 500 households in the State of Tlaxcala, in central Mexico. Household interviews were conducted by two trained physicians using the Rome II Modular Questionnaire, a health-care and medication used questionnaire and the CES-D depression scale. Results. The most common FGIDs were IBS: 16.0% (95% CI: 12.9–19.5; functional bloating: 10.8% (8.2–13.9; unspecified functional bowel disorder: 10.6% (8.0–13.6; and functional constipation (FC: 7.4% (5.3–10.1. Uninvestigated heartburn was common: 19.6% (16.2–23.4. All FGIDs were equally prevalent among both genders, except for IBS (P=0.001, IBS-C (P<0.001, IBS-A/M (P=0.049, and FC (P=0.039 which were more frequent in women. Subjects with FGIDs reported higher frequencies of medical visits: 34.6 versus 16.8%; use of medications: 40.7 versus 21.6%; (both P<0.001; and reported depression: 26.7 versus 6.7%, (P<0.001. Conclusion. In this first population-based study of FGIDs in Mexico, heartburn, IBS, functional distension, and FC were common. Only IBS, IBS-C, IBS-A/M, and FC were more frequent in women. Finally, FGIDs in Mexico had an increased burden of health care utilization and depression.

Time of day and eating behaviors are associated with the composition and function of the human gastrointestinal microbiota.

Background: Preclinical research has shown that the gastrointestinal microbiota exhibits circadian rhythms and that the timing of food consumption can affect the composition and function of gut microbes. However, there is a dearth of knowledge on these relations in humans. Objective: We aimed to determine whether human gastrointestinal microbes and bacterial metabolites were associated with time of day or behavioral factors, including eating frequency, percentage of energy consumed early in the day, and overnight-fast duration. Design: We analyzed 77 fecal samples collected from 28 healthy men and women. Fecal DNA was extracted and sequenced to determine the relative abundances of bacterial operational taxonomic units (OTUs). Gas chromatography-mass spectroscopy was used to assess short-chain fatty acid concentrations. Eating frequency, percentage of energy consumed before 1400, and overnight-fast duration were determined from dietary records. Data were analyzed by linear mixed models or generalized linear mixed models, which controlled for fiber intake, sex, age, body mass index, and repeated sampling within each participant. Each OTU and metabolite were tested as the outcome in a separate model. Results: Acetate, propionate, and butyrate concentrations decreased throughout the day ( P = 0.006, 0.04, and 0.002, respectively). Thirty-five percent of bacterial OTUs were associated with time. In addition, relations were observed between gut microbes and eating behaviors, including eating frequency, early energy consumption, and overnight-fast duration. Conclusions: These results indicate that the human gastrointestinal microbiota composition and function vary throughout the day, which may be related to the circadian biology of the human body, the microbial community itself, or human eating behaviors. Behavioral factors, including timing of eating and overnight-fast duration, were also predictive of bacterial abundances. Longitudinal intervention studies are needed to

Background: In different models of paralytic ileus, cannabinoid receptors are overexpressed and endogenous cannabinoids are massively released, contributing to gastrointestinal dysmotility. The antitumoral drug vincristine depresses gastrointestinal motility and a similar mechanism could participate in this effect. Therefore, our aim was to determine, using CB1 and CB2 antagonists, whether an increased endocannabinoid tone is involved in vincristine-induced gastrointestinal ileus. Methods: First, we confirmed the effects of vincristine on the gut mucosa, by conventional histological techniques, and characterized its effects on motility, by radiographic means. Conscious male Wistar rats received an intraperitoneal injection of vincristine (0.1–0.5 mg/kg), and barium sulfate (2.5 ml; 2 g/ml) was intragastrically administered 0, 24, or 48 h later. Serial X-rays were obtained at different time-points (0–8 h) after contrast. X-rays were used to build motility curves for each gastrointestinal region and determine the size of stomach and caecum. Tissue samples were taken for histology 48 h after saline or vincristine (0.5 mg/kg). Second, AM251 (a CB1 receptor antagonist) and AM630 (a CB2 receptor antagonist) were used to determine if CB1 and/or CB2 receptors are involved in vincristine-induced gastrointestinal dysmotility. Key results: Vincristine induced damage to the mucosa of ileum and colon and reduced gastrointestinal motor function at 0.5 mg/kg. The effect on motor function was particularly evident when the study started 24 h after administration. AM251, but not AM630, significantly prevented vincristine effect, particularly in the small intestine, when administered thrice. AM251 alone did not significantly alter gastrointestinal motility. Conclusions: The fact that AM251, but not AM630, is capable of reducing the effect of vincristine suggests that, like in other experimental models of paralytic ileus, an increased cannabinoid tone develops and is at least

The fasting plasma levels of nine gastrointestinal regulatory peptides were measured by radioimmunoassay in 13 stable patients with chronic renal failure, receiving hemodialysis treatment regularly and compared with those of ten healthy controls. The plasma concentrations of gastrin-releasing peptide, motilin, neurotensin, pancreatic polypeptide, peptide YY, somatostatin, substance P, and vasoactive intestinal peptide were increased. The plasma level of gastrin was not statistically different from that of the control (p=0.077). It is concluded that patients with chronic renal failure, receiving hemodialysis treatment regularly, have increased concentrations of eight of nine measured gastrointestinal regulatory peptides. The elevated levels of gastrointestinal peptides in patients with chronic renal failure may contribute to uremic gastrointestinal symptoms and dysfunctions. It is necessary to make a renal function evaluation before interpreting measured plasma levels of gastrointestinal regulatory peptides. 62 refs., 2 tabs

Gastrointestinal stromal tumour (GIST) represents the most common kind of mesenchymal tumour that arises from the alimentary tract. GIST is currently defined as a gastrointestinal tract mesenchymal tumour containing spindle cells (or less commonly epithelioid cells or rarely both) and showing CD117 (c-kit protein) positivity. Targeted molecular therapy of non-resectable GIST using imatinib, a specific tyrosine kinase receptor inhibitor, represents a real milestone in the management of solid malignancy. Imaging studies, both anatomical and functional, are playing an increasingly important role in management of patients with GIST. This review illustrates the radiological appearance of GISTs and the site-specific roles of each imaging tool. Clinical features and radiological differential diagnosis of GIST are also discussed

Functional gastrointestinal disorders (FGIDs) are common in children. Abdominal pain (AP) is the most common gastrointestinal (GI) symptom in children. The severity of AP drives medical consultations and quality of life in adult patients with irritable bowel syndrome (IBS). Thirty-eight percent of 8- to 15-year-old schoolchildren report AP weekly with 24% of those children reporting persistence of AP >8 weeks. Despite the high prevalence of AP, only 2% of school children seek medical attention for AP. Lack of parental knowledge on their child's symptoms may constitute one of the factors affecting the low ratio of consultation in children reporting AP. The aim was to assess parental reports of AP symptoms in a population of healthy community children. Data of 5 studies with identical methodology to assess GI symptoms in children with celiac disease (CD), cow's milk allergy (CMA), pyloric stenosis (PS), Henoch-Schönlein purpura (HSP), and stem cell transplant (SC) and their healthy siblings were reviewed: a phone questionnaire on GI symptoms and Pediatric Gastrointestinal Symptoms Rome III version questionnaire (QPGS-RIII). Inclusion criteria were healthy children 4 to 18 years of age with a sibling previously diagnosed with CD, CMA, PS, HSP, or SC. Data on 246 healthy children, mean age (9.8 years, range 3-24, 112 girls) were obtained. Parents reported presence of AP in the last 8 weeks before the telephone contact in 20 (8.1%) children (age range 4-18 years, 11 girls). There was no significant difference in AP prevalence between boys and girls (P = 0.64). Six children (2.4%) met QPGS-RIII diagnostic criteria for FGIDs: 3 functional abdominal pain (FAP) and 3 IBS. AP was common in community children. FAP was the most common FGID among healthy community children. The prevalence of AP by parental report is lower than the previously published prevalence of AP reported by children. Lack of awareness of children's symptoms may play a role in the low ratio of

Sleep disorders are often associated with functional gastrointestinal disorders (FGIDs). This study aims to evaluate the association of sleep disorders with specific FGIDs and to assess the related importance of psychological disorders. We included 1009 consecutive patients with FGIDs (70.9% females). The patients completed a Rome III questionnaire and after a psychological evaluation on anxiety and depression they were classified according to their sleep disorders using a 7-point grading scale: Groups 1-3, drowsiness (severe, moderate, mild); Group 4, no change; Groups 5-7, insomnia (mild, moderate, severe). Multinomial logistic regression using sleep group as a dependent variable with no sleep change as reference and body mass index, FGIDs, anxiety and depression as independent variables were used for statistical analysis. Altogether 667 (66.1%) patients reported changes in sleep disorders, of whom 487 (48.3%) had decreased sleep and 180 (17.8%) had increased sleep while 342 (33.9%) reported no change. Depression was lower in patients with no change in sleep pattern and increased with the severity of their sleep disorder (P proctalgia fugax. Sleep disorders are associated with FGIDs, especially in the presence of depressive symptoms. © 2018 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

The role of angiography in the diagnosis and treatment of gastrointestinal hemorrhage is discussed. Three categories of gastrointestinal bleeding are considered: upper gastrointestinal bleeding due to gastroesophageal varices, upper gastrointestinal bleeding of arterial or capillary origin, and lower gastrointestinal bleeding. The advantages and disadvantages of angiography are compared with those of radionuclide scanning and endoscopy or colonoscopy. It is anticipated that, as radionuclide scans are more widely employed, angiography will eventually be performed only in those patients with positive scans

Full Text Available Objective. To determine the clinical and pathogenetic role in the formation of gastrointestinal hyperactivity and chronic allergic gastritis in children. Patients and methods. We observed 82 children aged 6 to 16 years. To verify the diagnosis all the children performed endoscopy of the upper gastrointestinal tract, intragastric pHmeter. To confirm the genesis of atopic disease of patients determined the level general IgE in the serum by ELISA. Results. As a result of studies we find, that in majority (92.7±2.9% patients examined early symptoms of gastrointestinal hyperactivity were diagnosed in the first six months of life. Gastrointestinal hyperactivity in infants is manifested by increased functional reaction of the gastrointestinal system, namely the disorders of the digestive and motorevacuation function of the gastrointestinal tract and symptoms of atopic dermatitis. In older children gastrointestinal hyperactivity transformed intoallergic gastritis, which is manifested by destructive changes of the gastric mucosa, increased production of hydrochloric acid , motility disorders of the gastrointestinal tract mainly in the form of duodenogastric reflux. It was found that the determining factors of the formation of allergic inflammation should be considered a high percentage of family history as a gastroenterological and allergic diseases, disorders physiological feeding graphics and nutrition of children from the first days of life. A characteristic feature of current gastroenterological diseases in patients with gastrointestinal hyperactivity was the absence of seasonal exacerbations, severe pain in the right upper quadrant, belching and flatulence, against the background of destructive changes in the gastric mucosa. Conclusions. We have identified specific clinical symptoms is pathognomonic for children with gastrointestinal hyperactivity and provides the opportunity to be watchful for the diagnosis of allergic changes in the gastric

Aspirin is widely used for the prevention of cardiovascular and cerebrovascular diseases for the past few years. However, much attention has been paid to the adverse effects associated with aspirin such as gastrointestinal bleeding. How to weigh the benefits and hazards? The current study aimed to assess the feasibility of a cardiovascular/gastrointestinal risk calculator, AsaRiskCalculator, in predicting gastrointestinal events in Chinese patients with myocardial infarction (MI), determining unique risk factor(s) for gastrointestinal events to be considered in the calculator. The MI patients who visited Shapingba District People's Hospital between January 2012 and January 2016 were retrospectively reviewed. Based on gastroscopic data, the patients were divided into two groups: gastrointestinal and nongastrointestinal groups. Demographic and clinical data of the patients were then retrieved for statistical analysis. Univariate and multiple logistic regression analyses were used to identify independent risk factors for gastrointestinal events. The receiver operating characteristic (ROC) curves were used to assess the predictive value of AsaRiskCalculator for gastrointestinal events. A total of 400 MI patients meeting the eligibility criteria were analyzed, including 94 and 306 in the gastrointestinal and nongastrointestinal groups, respectively. The data showed that age, male gender, predicted gastrointestinal events, and Helicobacter pylori (HP) infection were positively correlated with gastrointestinal events. In multiple logistic regression analysis, predicted gastrointestinal events and HP infection were identified as risk factors for actual gastrointestinal events. HP infection was highly predictive in Chinese patients; the ROC curve indicated an area under the curve of 0.822 (95% confidence interval: 0.774-0.870). The best diagnostic cutoff point of predicted gastrointestinal events was 68.0‰, yielding sensitivity and specificity of 60.6% and 93

Functional studies of the autonomic innervation in the photophores of luminescent fishes are scarce. The majority of studies have involved either the stimulation of isolated photophores or the modulatory effects of adrenaline-induced light emission. The fish skin is a highly complex organ that performs a wide variety of physiological processes and receives extensive nervous innervations. The latter includes autonomic nerve fibers of spinal sympathetic origin having a secretomotor function. More recent evidence indicates that neuropeptide-containing nerve fibers, such as those that express tachykinin and its NK1 receptor, neuropeptide Y, or nitric oxide, may also play an important role in the nervous control of photophores. There is no anatomical evidence that shows that nNOS positive (nitrergic) neurons form a population distinct from the secretomotor neurons with perikarya in the sympathetic ganglia. The distribution and function of the nitrergic nerves in the luminous cells, however, is less clear. It is likely that the chemical properties of the sympathetic postganglionic neurons in the ganglia of luminescent fishes are target-specific, such as observed in mammals.

Exposure of the gut to ionising radiation may induce gastrointestinal damage and dysfunction. Early effects such as nausea, vomiting and diarrhea, anorexia may be observed within the first 24 h after irradiation. Such symptoms are seen even with doses as low as 1 Gy. later effects and the onset of the gastrointestinal syndrome are seen at higher doses (10 Gy) and include gastric emptying inhibition, intestinal hemorrhages, disturbances in water and electrolytes balance and septicemia. The severity of which depends on the nature, dose and dose rate received. The mechanism underlying these changes was unclear; it has long been known that exposure to ionising radiation affects intestinal morphology usually because of inhibition of mitotic activity at the level of the crypt enterocyst. The various physiological functions of the gastrointestinal tract are controlled by a wide variety of agents as neurotransmitters, neuropeptides. Radiation induces alterations in hormonal release and response. The present study carried out in the rat focuses on Gastrin Releasing Peptide (GRP), a gastrointestinal neuropeptide present in the central nervous system and in the gut endocrine cells were released into blood. The GRP controls food intake, pancreatic enzyme secretions, gastric emptying, intestinal motility and cellular proliferation. The aim was to investigate the effects of gamma and neutron/gamma on plasma and gastrointestinal tissue levels of GRP

New and Unexpected Biological Functions for the Src-Homology 2 Domain-Containing Phosphatase SHP-2 in the Gastrointestinal TractSummary

Geneviève Coulombe

2016-01-01

Full Text Available SHP-2 is a tyrosine phosphatase expressed in most embryonic and adult tissues. SHP-2 regulates many cellular functions including growth, differentiation, migration, and survival. Genetic and biochemical evidence show that SHP-2 is required for rat sarcoma viral oncogene/extracellular signal-regulated kinases mitogen-activated protein kinase pathway activation by most tyrosine kinase receptors, as well as by G-protein–coupled and cytokine receptors. In addition, SHP-2 can regulate the Janus kinase/signal transducers and activators of transcription, nuclear factor-κB, phosphatidyl-inositol 3-kinase/Akt, RhoA, Hippo, and Wnt/β-catenin signaling pathways. Emerging evidence has shown that SHP-2 dysfunction represents a key factor in the pathogenesis of gastrointestinal diseases, in particular in chronic inflammation and cancer. Variations within the gene locus encoding SHP-2 have been associated with increased susceptibility to develop ulcerative colitis and gastric atrophy. Furthermore, mice with conditional deletion of SHP-2 in intestinal epithelial cells rapidly develop severe colitis. Similarly, hepatocyte-specific deletion of SHP-2 induces hepatic inflammation, resulting in regenerative hyperplasia and development of tumors in aged mice. However, the SHP-2 gene initially was suggested to be a proto-oncogene because activating mutations of this gene were found in pediatric leukemias and certain forms of liver and colon cancers. Moreover, SHP-2 expression is up-regulated in gastric and hepatocellular cancers. Notably, SHP-2 functions downstream of cytotoxin-associated antigen A (CagA, the major virulence factor of Helicobacter pylori, and is associated with increased risks of gastric cancer. Further compounding this complexity, most recent findings suggest that SHP-2 also coordinates carbohydrate, lipid, and bile acid synthesis in the liver and pancreas. This review aims to summarize current knowledge and recent data regarding the

Full Text Available AbstractBackground: Despite the role of metacognition in psychopathology, no studies have explored this construct in the area of gastrointestinal disorders. Moreover, for many times there was a categorization between organic and functional gastrointestinal disorders. The aim of this study was to compare dysfunctional metacognitive beliefs between patients with functional bowel disorders and patients with organic bowel disorders. The purpose of this work was also to examine the relations between metacognitions, alexithymia and symptoms of the patients on the basis of diagnosis.Methods: A between-subject non parametric and correlational design was employed. We formed three clinical groups from a population of patients with gastrointestinal disorders and on the basis of the ‘organic’ and ‘functional’ diagnosis. All the participants underwent the Metacognitions Questionnaire 30, the Toronto Alexithymia Scale-20 and the Gastrointestinal Symptom Rating Scale.Results: There were no significant differences between the three clinical groups on MCQ-30 and TAS-20 scores. However, there were significant correlations based on diagnosis of the gastrointestinal disorder between alexithymic features and metacognitive dysfunctional beliefs.Conclusions: Our results underline the role of metacognitions for both patients with organic and functional gastrointestinal disorders. Moreover, the results highlight the importance to consider these aspects in patients with organic gastrointestinal disorder. Keywords: alexithymia; Crohn’s disease; IBS;  metacognition; ulcerative colitis. 

Probiotics for Gastrointestinal Conditions: A Summary of the Evidence.

Wilkins, Thad; Sequoia, Jacqueline

Probiotics contain microorganisms, most of which are bacteria similar to the beneficial bacteria that occur naturally in the human gut. Probiotics have been widely studied in a variety of gastrointestinal diseases. The most-studied species include Lactobacillus, Bifidobacterium, and Saccharomyces. However, a lack of clear guidelines on when to use probiotics and the most effective probiotic for different gastrointestinal conditions may be confusing for family physicians and their patients. Probiotics have an important role in the maintenance of immunologic equilibrium in the gastrointestinal tract through the direct interaction with immune cells. Probiotic effectiveness can be species-, dose-, and disease-specific, and the duration of therapy depends on the clinical indication. There is high-quality evidence that probiotics are effective for acute infectious diarrhea, antibiotic-associated diarrhea, Clostridium difficile- associated diarrhea, hepatic encephalopathy, ulcerative colitis, irritable bowel syndrome, functional gastrointestinal disorders, and necrotizing enterocolitis. Conversely, there is evidence that probiotics are not effective for acute pancreatitis and Crohn disease. Probiotics are safe for infants, children, adults, and older patients, but caution is advised in immunologically vulnerable populations.

Europeans consume large quantities of bakery products, although these are known as one of the food categories that potentially leads to postprandial symptoms (such as fullness and bloating). The aim of this study was to evaluate the effects of sourdough baked goods on gastric emptying and gastrointestinal fermentation and symptoms in healthy people. In a double-blind, randomized crossover study, 2 sourdough croissants (SCs) or 2 brewer's yeast croissants (BCs) were served as single meals to 17 healthy adults [9 women; age range: 18-40 y; body mass index range (in kg/m2): 18-24]. Gastric volume (GV) was evaluated by magnetic resonance to calculate gastric-emptying rate in the 3-h interval after croissant ingestion. A hydrogen breath test was performed to measure hydrogen production after SC and BC ingestion. Palatability and postprandial gastrointestinal symptoms (discomfort, nausea, fullness, and bloating) over a 4-h period after the meal were evaluated. The area under the curve (AUC) was used to evaluate the overall effects on all variables tested. The total GV AUC was reduced by 11% during the 3 h after the consumption of SCs compared with BCs (P = 0.02). Hydrogen production during the 4-h interval after ingestion of SCs was 30% lower than after BCs (P = 0.03). SCs were rated as being >2 times as palatable as BCs (P bakery products could promote better postprandial gastrointestinal function in healthy adults and be more acceptable than those prepared with brewer's yeast. This trial was registered at www.clinicaltrials.gov as NCT03207516.

Objective: To study the role of gallbladder kinetics and plasma levels of gastrointestinal hormones in the mechanism of functional dyspepsia. Methods: Gallbladder ejection fractions (GBEF) were determined with 99 Tc m radionuclide imaging, and plasma levels of motilin (MTL), cholecystokinin (CCK), vasoactive intestinal peptide (VIP) and somatostatin (SS) were measured with radioimmunoassay. Thirty-two patients with functional dyspepsia of dyskinetic type (FD group) and 20 normal volunteers in control group were studied. Results: The preprandial and postprandial gallbladder ejection fractions (GBEF) and MTL levels were both obviously lower in FD group (P preprandial = 0.82, P postprandial 0.94, P 0.05), while the levels of postprandial CCK were significantly decreased in FD group (P preprandial -0.81, P postprandial = - 0.47, P 0.05). Conclusions: Patients with FD of dyskinetic type might have a significant decrease of preprandial and postprandial gallbladder emptying. The decrease of plasma levels of gastrointestinal hormones. MTL, CCK and the elevation of VIP might be the cause of slow gallbladder emptying and part of the basic pathophysiology in FD

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

2013-01-01

Background The association of fructose and lactose intolerance and malabsorption with the symptoms of different functional gastrointestinal disorders (FGID) remains unclear. Aim To investigate the prevalence of fructose and lactose intolerance (symptom induction) and malabsorption and their association with clinical gastrointestinal (GI) as well as non-GI symptoms in FGID and the outcome of dietary intervention. Methods Fructose and lactose intolerance (defined by positive symptom index) and malabsorption (defined by increased hydrogen/methane) were determined in 1372 FGID patients in a single centre using breath testing. Results were correlated with clinical symptoms in different FGID Rome III subgroups. The effectiveness of a targeted saccharide-reduced diet was assessed after 6–8 weeks. Results Intolerance prevalence across all FGIDs was 60% to fructose, 51% to lactose and 33% to both. Malabsorption occurred in 45%, 32% and 16% respectively. There were no differences in intolerance or malabsorption prevalence between FGID subgroups. FGID symptoms correlated with symptoms evoked during testing (r = 0.35–0.61. P 80% of intolerant patients, irrespective of malabsorption. Conclusions Fructose and lactose intolerances are common in FGID and associated with increased non-GI symptoms, but not with specific FGID subtypes. Symptoms experienced during breath testing, but not malabsorption, correlate with FGID symptoms. Effective symptom relief with dietary adaptation is not associated with malabsorption. Mechanisms relating to the generation of GI and non-GI symptoms due to lactose and fructose in FGID need to be explored further. PMID:23574302

Many people with functional gastrointestinal disorders (FGIDs) face significant barriers in accessing psychological treatments that are known to reduce symptoms and their psychological sequelae. This study examined the feasibility and initial outcomes of a transdiagnostic and internet-delivered cognitive behaviour therapy (iCBT) intervention, the Chronic Conditions Course, for adults with functional gastrointestinal disorders (FGIDs). A single-group feasibility open trial design was employed and administered to twenty seven participants. The course ran for 8 weeks and was provided with weekly contact from a Clinical Psychologist. Seventy percent of participants completed the course within the 8 weeks and 81.5% provided data at post-treatment. High levels of satisfaction were observed and relatively little clinician time (M = 42.70 min per participant; SD = 46.25 min) was required. Evidence of clinical improvements in FGID symptoms (ds ≥ 0.46; avg. improvement ≥21%), anxiety symptoms (ds ≥ 0.99; avg. improvement ≥42%), and depression symptoms (ds ≥ 0.75; avg. improvement ≥35%) were observed, which either maintained or continued to improve to 3-month follow-up. Evidence of improvement was also observed in pain catastrophising and mental-health related quality of life, but not physical-health related quality of life. These findings highlight the potential value of transdiagnostic internet-delivered programs for adults with FGIDs and support for the conduct of larger-scale controlled studies.

Cognitive processing in putative functional gastrointestinal disorder: rumination yields orientation to social threat not pain.

Science.gov (United States)

Martin, Maryanne; Chapman, Sarah C E

2010-02-01

Two possible roles of selective attention in the development and maintenance of functional gastrointestinal disorders (FGID) such as irritable bowel syndrome (IBS) were examined. First, hypervigilance to pain within FGID may exacerbate pain perception and pain-related distress. Second, hypervigilance to socially threatening stimuli could account for the disrupted social functioning reported by patients. Furthermore, stress-related variations in reported symptom severity and functioning impairments may reflect changes in cognitive bias with psychological state. Patterns of selective attention were probed within a sample of putative FGID participants (pFGID). The effect of rumination induction on performance on a modified exogenous cueing task was examined. Thirty-three women with pFGID and 27 matched controls responded to dot probes following pain, social threat and neutral word cues, both before and after rumination (passive self-focused thought), or distraction induction. Reaction times revealed that after rumination but not neutral distraction, pFGID participants showed enhanced attention to social threat words, but not to pain or neutral words. Between-group differences in mood, anxiety or depression could not account for these effects. These results implicate selective attention in social but not pain-related idiosyncrasies in FGID including IBS.

The gastrointestinal tract is controlled by the independent enteric nervous system. It is also closely connected to the central nervous system, and bi-directional communication exists between them. The communication involves neural pathways as well as immune and endocrine mechanisms. The brain-gut axis plays a prominent role in the modulation of gut functions. Signals from different sources (e.g. sound, sight, smell, somatic and visceral sensations, pain) reach the brain. These inputs are modified by memory, cognition and affective mechanisms and integrated within the neural circuits of the central nervous system, spinal cord, autonomic and enteral nervous systems. These inputs can have physiologic effects, such as changes in motility, secretion, immune function, and blood flow to the gastrointestinal tract. One of the most important neurotransmitters is serotonin that plays a key role in the pathogenesis of the most common chronic functional gastrointestinal disorder: the irritable bowel syndrome. It is a biopsychosocial disease, resulting from the dysregulation of the brain-gut axis. Endogenous pain facilitation rather than inhibition, pathologic gradation of visceral perception and reduced threshold for pain are all evident in these patients. Abuse history is common in their anamnesis. Exaggerated conscientiousness, perfectionism, oversensitivity, feeling of deficiency in effectiveness, and higher demand for social parity, neuroticism and alexithymia have been detected among their constant personality features. Females are also characterized by gender role conflict and low assertiveness. Antidepressants and psychotherapy have important roles in their treatment. Also patients with inflammatory bowel disease are characterized by neuroticism and alexithymia and altered mother-child attachment is often described in their anamnesis. Autonomic neuropathy is a frequent and early neurological complication. Reflux disease and obstructive sleep apnea mutually generate

AIM: To investigate the feasibility of treatment for upper gastrointestinal fistula and leakage with personal stage nutrition support.METHODS: Forty-three patients with upper gastrointestinal fistula and leakage were randomly divided into two groups. Patients in group A were treated with personal stage nutrition support and patients in group B were treated with total parental nutrition (TPN) in combination with operation.Nutritional states of the candidates were evaluated by detecting albumin (Alb) and pre-Alb. The balance between nutrition and hepatic function was evaluated by measurement of aspartate aminotransferase (AST),alanine aminotransferase (ALT) and total bilirubin (Tbill) before and after operation. At the same time their complications and hospitalized time were surveyed.RESULTS: Personal stage nutrition support improved upper gastrointestinal fistula and leakage. The nutrition state and hepatic function were better in patients who received personal stage nutrition support than in those who did not receive TPN. There was no significant difference in the complication and hospitalized time in the two groups of patients.CONCLUSION: Upper gastrointestinal fistula and leakage can be treated with personal stage nutrition support which is more beneficial for the post-operation recovery and more economic than surgical operation.

This article reviews current imaging techniques, methods for data processing and principles for evaluating results when scintigraphy is used to assess gastrointestinal motility. Furthermore, clinical indications for performing scintigraphy are reviewed.......Gastrointestinal transit reflects overall gastrointestinal motor activity and is regulated by a complex interplay between neural and hormonal stimuli. Thus, transit measurements provide a measure of the combined effects of gastrointestinal muscular activity and feedback from the gut and brain....... Dysmotility in the different major segments of the gastrointestinal tract may give rise to similar symptoms; hence, localizing transit abnormalities to a specific segment is a valuable element of diagnostic evaluation.

George, Michael D; Asmuth, David M

2014-06-01

This review describes the impact of HIV infection on gut-associated lymphoid tissue, the mechanisms for persistent gut-associated lymphoid tissue dysfunction despite effective antiretroviral therapy, and potential strategies to restore gut-associated lymphoid tissue function and promote immune reconstitution. Recent studies indicate that unresolved microbial translocation and intestinal dysbiosis may continue to promote enteropathy as well as HIV-associated and non-HIV-associated conditions in many HIV patients who otherwise maintain therapeutic control of systemic viral replication. Several novel therapeutic approaches to reduce intestinal inflammation and mitigate microbial translocation may hold promise for restoring gastrointestinal health and thereby increasing the efficacy of immune reconstitution in HIV-infected patients undergoing antiretroviral therapy.

Full Text Available A 56-year-old African patient received a kidney from a deceased donor with 4 HLA mismatches in April 2013. He received immunosuppression with basiliximab, tacrolimus, mycophenolate mofetil, and prednisone. Immediate diuresis and a good allograft function were soon observed. Six months later, the serum creatinine level increased to 2.6 mg/dL. A renal allograft biopsy revealed interstitial fibrosis and tubular atrophy grade II. Toxicity of calcineurin inhibitor was assumed and, after a switch for everolimus, renal function improved. However, since March 2014, renal function progressively deteriorated. A second allograft biopsy showed no new lesions. Two months later, the patient was admitted due to anuria, haematochezia with anaemia, requiring 5 units of packed red blood cells, and diffuse skin thickening. Colonoscopy showed haemorrhagic patches in the colon and the rectum; histology diagnosis was Kaposi sarcoma (KS. A skin biopsy revealed cutaneous involvement of KS. Rapid clinical deterioration culminated in death in June 2014. This case is unusual as less than 20 cases of KS with gross gastrointestinal bleeding have been reported and only 6 cases had the referred bleeding originating in the lower gastrointestinal tract. So, KS should be considered in differential diagnosis of gastrointestinal bleeding in some kidney transplant patients.

The pathophysiology behind functional gastrointestinal disease (FGID) has not been defined, but an intestinal accumulation of fermentable short-chain carbohydrates (FODMAPs) is thought to be involved. A restricted coffee intake is recommended. The aim was to investigate if symptoms of FGID were associated with intake of certain foods (including FODMAPs), as well as beverages (including coffee and tea). Data were used from participants, age range 45-75 years, who had answered the EpiHealth questionnaire about their background factors, health status and intake of food and beverages. After exclusion of organic bowel diseases, 16,840 participants remained. The impact of food and beverages on functional abdominal pain, functional bloating, functional constipation and functional diarrhea were examined by adjusted binary logistic regression. Wholemeal bread (Swedish cracker) (OR: 1.361; 95% CI: 1.001-1.851) and white bread (low fiber content) (OR: 1.527; 95% CI: 1.075-2.169) were associated with constipation, whereas soft wholemeal bread (high fiber content) was associated with diarrhea (OR: 1.601; 95% CI: 1.040-2.463). Cheese was associated with bloating (OR: 1.460; 95% CI: 1.004-2.123). A high tea intake was associated with abdominal pain (p for trend =.003), bloating (p for trend = .039) and diarrhea (p for trend <.001), whereas coffee intake was associated with a decreased risk of abdominal pain (p for trend = .002) and bloating (p for trend = .007). High soda intake associated with abdominal pain and bloating and juice with diarrhea. There are weak associations between intake of grain and dairy products and FGID symptoms. Tea is associated with increased risks, whereas coffee is associated with lower risks, of FGID symptoms.

The nature of catecholamine-containing neurons in the enteric nervous system in relationship with organogenesis, normal human anatomy and neurodegeneration.

Science.gov (United States)

Natale, G; Ryskalin, L; Busceti, C L; Biagioni, F; Fornai, F

The gastrointestinal tract is provided with extrinsic and intrinsic innervation. The extrinsic innervation includes the classic vagal parasympathetic and sympathetic components, with afferent sensitive and efferent secretomotor fibers. The intrinsic innervations is represented by the enteric nervous system (ENS), which is recognized as a complex neural network controlling a variety of cell populations, including smooth muscle cells, mucosal secretory cells, endocrine cells, microvasculature, immune and inflammatory cells. This is finalized to regulate gastrointestinal secretion, absorption and motility. In particular, this network is organized in several plexuses each one providing quite autonomous control of gastrointestinal functions (hence the definition of "second brain"). The similarity between ENS and CNS is further substantiated by the presence of local sensitive pseudo- unipolar ganglionic neurons with both peripheral and central branching which terminate in the enteric wall. A large variety of neurons and neurotransmitters takes part in the ENS. However, the nature of these neurons and their role in the regulation of gastrointestinal functions is debatable. In particular, the available literature reporting the specific nature of catecholamine- containing neurons provides conflicting evidence. This is critical both for understanding the specific role of each catecholamine in the gut and, mostly, to characterize specifically the enteric neuropathology occurring in a variety of diseases. An emphasis is posed on neurodegenerative disorders, such as Parkinson's disease, which is associated with the loss of catecholamine neurons. In this respect, the recognition of the nature of such neurons within the ENS would contribute to elucidate the pathological mechanisms which produce both CNS and ENS degeneration and to achieve more effective therapeutic approaches. Despite a great emphasis is posed on the role of noradrenaline to regulate enteric activities only a few

Autism spectrum disorder (ASD) is an increasingly common behavioral condition that frequently presents with gastrointestinal (GI) disturbances. It is not clear, however, how gut dysfunction relates to core ASD features. Multiple, rare hyperfunctional coding variants of the serotonin (5-HT) transporter (SERT, encoded by SLC6A4) have been identified in ASD. Expression of the most common SERT variant (Ala56) in mice increases 5-HT clearance and causes ASD-like behaviors. Here, we demonstrated that Ala56-expressing mice display GI defects that resemble those seen in mice lacking neuronal 5-HT. These defects included enteric nervous system hypoplasia, slow GI transit, diminished peristaltic reflex activity, and proliferation of crypt epithelial cells. An opposite phenotype was seen in SERT-deficient mice and in progeny of WT dams given the SERT antagonist fluoxetine. The reciprocal phenotypes that resulted from increased or decreased SERT activity support the idea that 5-HT signaling regulates enteric neuronal development and can, when disturbed, cause long-lasting abnormalities of GI function. Administration of a 5-HT4 agonist to Ala56 mice during development prevented Ala56-associated GI perturbations, suggesting that excessive SERT activity leads to inadequate 5-HT4–mediated neurogenesis. We propose that deficient 5-HT signaling during development may contribute to GI and behavioral features of ASD. The consequences of therapies targeting SERT during pregnancy warrant further evaluation. PMID:27111230

Whether gastrointestinal motor and sensory function is primary cause or secondary effect of abnormal body weight is uncertain. Moreover, studies relating continuous postprandial sensations of satiation to measurable pathology are scarce. This work assessed postprandial gastrointestinal function and concurrent sensations of satiation across a wide range of body weight and after weight change. Patients with anorexia nervosa (AN) and obesity (OB) were investigated in reference to normal weight controls (HC). AN were additionally investigated longitudinally. Gastric emptying, antral contractions and oro-cecal transit after ingestion of a solid meal were investigated by MRI and 13 C-lactose-ureide breath test. The dependency of self-reported sensations of satiation on the varying degree of stomach filling during gastric emptying was compared between groups. 24 AN (BMI 14.4 (11.9-16.0) kg/m 2 ), 16 OB (34.9 (29.6-41.5) kg/m 2 ) and 20 HC (21.9 (18.9-24.9) kg/m 2 ) were studied. Gastric half-emptying time (t 50 ) was slower in AN than HC (p = 0.016) and OB (p = 0.007), and a negative association between t 50 and BMI was observed between BMI 12 and 25 kg/m 2 (p = 0.007). Antral contractions and oro-cecal transit were not different. For any given gastric content volume, self-reported postprandial fullness was greater in AN than in HC or OB (p < 0.001). After weight rehabilitation, t 50 in AN tended to become shorter (p = 0.09) and postprandial fullness was less marked (p < 0.01). A relationship between body weight and gastric emptying as well as self-reported feelings of satiation is present. AN have slower gastric emptying and heightened visceral perception compared to HC and OB. Longitudinal follow-up after weight rehabilitation in AN suggests these abnormalities are not a primary feature, but secondary to other factors that determine abnormal body weight.

Flatfish metamorphosis is a hormone regulated post-embryonic developmental event that transforms a symmetric larva into an asymmetric juvenile. In altricial-gastric teleost fish, differentiation of the stomach takes place after the onset of first feeding, and during metamorphosis dramatic molecular and morphological modifications of the gastrointestinal (GI-) tract occur. Here we present the functional ontogeny of the developing GI-tract from an integrative perspective in the pleuronectiforme Atlantic halibut, and test the hypothesis that the multiple functions of the teleost stomach develop synchronously during metamorphosis. Onset of gastric function was determined with several approaches (anatomical, biochemical, molecular and in vivo observations). In vivo pH analysis in the GI-tract lumen combined with quantitative PCR (qPCR) of α and β subunits of the gastric proton pump (H+/K+-ATPase) and pepsinogen A2 indicated that gastric proteolytic capacity is established during the climax of metamorphosis. Transcript abundance of ghrelin, a putative orexigenic signalling molecule produced in the developing stomach, correlated (p metamorphosis, and was thus independent of this event. Mechanical breakdown of food and transportation of chyme through the GI-tract was observed in vivo and resulted from phasic and propagating contractions established well before metamorphosis. The number of contractions in the midgut decreased at metamorphic climax synchronously with establishment of the stomach's proteolytic capacity and its increased peristaltic activity. Putative osmoregulatory competence of the GI-tract, inferred by abundance of Na+/K+-ATPase α transcripts, was already established at the onset of exogenous feeding and was unmodified by metamorphosis. The functional specialization of the GI-tract was not exclusive to metamorphosis, and its osmoregulatory capacity and reservoir function were established before first feeding. Nonetheless, acid production and the

The aim of this study was to investigate the effects of mosapride combined with probiotics on gastrointestinal function and growth and development in premature infants. A total of 240 premature infants treated at Weifang People's Hospital between June 2012 and May 2015 who matched our criteria were randomly divided into three groups of 80 cases each. Group A received routine treatment, group B received routine treatment combined with live B. subtilis and E. faecium granules with multivitamins (Medilac-Vita), and group C received routine treatment and Saccharomyces boulardii sachets (Bioflor). Mosapride was administered to patients in groups B and C to promote intestinal peristalsis. Gastrin and bilirubin levels, as well as jaundice fade time, were recorded. Growth and development condition (i.e., head circumference and weight), duration and incidence of feeding intolerance (FI), as well as other symptoms were also analyzed. By day 14, gastrin concentrations in groups B and C were significantly higher than those in group A (Pjaundice duration in group A was significantly longer (Pprobiotics can effectively reduce FI incidence in premature infants, shorten enteral feeding time, promote the absorption of required nutrients, and promote the development and recovery of early physiological weight loss in preterm infants.

Full Text Available Objective: Ingested foreign bodies in gastrointestinal tract are a common event which can cause serious morbidity and mortality in the children and adult population. For this reason, early diagnosis and treatment are crucial for preventing these life threatening complications. In this study, we aimed to analyze the characteristics of the patients with upper gastrointestinal foreign bodies that were treated in our department. Methods: Patients diagnosed with upper gastrointestinal foreign bodies who were admitted to our hospital between February 2010 and August2013 were evaluated retrospectively. The data regarding their age, gender, clinical profile, type and localization of the esophageal foreign body, performed endoscopic procedure and initial symptoms of the patients were noted and analyzed statistically. Results: Thirty-eight patients with a diagnosis of gastrointestinal foreign body were included in this study. Of these patients, 21 were male and 17 were female. The youngest patient was 17 years old and the oldest patient was 79 years old. Most of the foreign bodies (%55.3 detected in the stomach. Food waste and metallic objects in 21 and 16 patients respectively. The most common complaint was dysphagia (%50. After endoscopic intervention three of the patients were directed to surgery. Conclusion: Early recognition and treatment of gastrointestinal foreign bodies is important as their complications are life threatening. The best method of removal of foreign bodies is controversial. Early management with upper gastrointestinal endoscopy is the most efficient and safe treatment method in current conditions.

Gastrointestinal bleeding remains a major diagnostic problem. Although advances have been made in the medical and surgical methods of managing gastrointestinal bleeding, the commonly employed techniques of barium radiography, endoscopy, and angiography may not successfully localize the site and define the cause of gastrointestinal bleeding. Two widely available technetium-99m-labeled radiopharmaceuticals, sulfur colloid and red blood cells are currently used in the evaluation of patients who are bleeding from the gastrointestinal tract. Surgically confirmed 19 patients with use of 99m Tc-sulfur colloid (7 cases) and 99m Tc-RBC (12 cases) were retrospectively evaluated. The overall sensitivity of scintigraphy in detection of bleeding and localization of bleeding site was 68% and 84%, respectively. The authors conclude that bleeding scintigraphy is a safe, sensitive, and non-invasive method as an effective screening test before performing angiography or surgery.

The viability and functionality of probiotics may be influenced by industrial production processes resulting in a decrease in probiotic efficiency that benefit the health of humans. This study aimed to investigate the probiotic characteristics of Bifidobacterium strains isolated from fecal samples of healthy Thai infants. In the present work, three local strains (BF014, BF052, and BH053) belonging to Bifidobacterium animalis showed a great resistance against conditions simulating the gastrointestinal tract. Among these, B. animalis BF052 possessed considerable probiotic properties, including high acid and bile tolerance, strong adhesion capability to Caco-2 cells, and inhibitory activity against pathogens including Salmonella typhimurium and Vibrio cholerae. This strain also exhibited a high survival rate compared to commercial strains during storage in a wide variety of products, including pasteurized milk, soy milk, drinking yogurt, and orange juice. The impact of food processing processes as well as the freeze-drying process, storage of freeze-dried powders, and incorporation of freeze-dried cells in food matrix on probiotic properties was also determined. The stability of the probiotic properties of the BF052 strain was not affected by food processing chain, especially its resistance in the simulated gastrointestinal conditions and its adherence ability to Caco-2 cells. It indicates that it satisfies the criteria as a potential probiotic and may be used as an effective probiotic starter in food applications.

Background and study aims: Gastrointestinal bleeding in children and adolescents accounts for up to 20 % of referrals to gastroenterologists. Detailed management guidelines exist for gastrointestinal bleeding in adults, but they do not encompass children and adolescents. The aim of this study was to assess gastrointestinal bleeding in pediatric patients and to determine an investigative management algorithm accounting for the specifics of children and adolescents. Patients and methods: Pediatric patients with gastrointestinal bleeding admitted to our endoscopy unit from 2001 to 2009 (n = 154) were identified. Retrospective statistical and neural network analysis was used to assess outcome and to determine an investigative management algorithm. Results: The source of bleeding could be identified in 81 % (n = 124/154). Gastrointestinal bleeding was predominantly lower gastrointestinal bleeding (66 %, n = 101); upper gastrointestinal bleeding was much less common (14 %, n = 21). Hematochezia was observed in 94 % of the patients with lower gastrointestinal bleeding (n = 95 of 101). Hematemesis (67 %, n = 14 of 21) and melena (48 %, n = 10 of 21) were associated with upper gastrointestinal bleeding. The sensitivity and specificity of a neural network to predict lower gastrointestinal bleeding were 98 % and 63.6 %, respectively and to predict upper gastrointestinal bleeding were 75 % and 96 % respectively. The sensitivity and specifity of hematochezia alone to predict lower gastrointestinal bleeding were 94.2 % and 85.7 %, respectively. The sensitivity and specificity for hematemesis and melena to predict upper gastrointestinal bleeding were 82.6 % and 94 %, respectively. We then developed an investigative management algorithm based on the presence of hematochezia and hematemesis or melena. Conclusions: Hematochezia should prompt colonoscopy and hematemesis or melena should prompt esophagogastroduodenoscopy. If no

Full Text Available Background. In 60–70 % of cases of visiting a doctor, the leading complaints from parents, who have children of the first months of life, are symptoms of discomfort from the infant’s gastrointestinal tract: regurgitation, intestinal colic, diarrhea, constipation, which in most cases are not associated with organic changes and arise in apparently healthy children, without causing significant changes in their health status. The most frequent manifestations of functional disorders of the gastrointestinal tract include regurgitation — passive reflux of a small amount of gastric contents into the pharynx, the oral cavity and outwards. The tendency to regurgitation, accor-ding to various authors, is observed in 20–85 % of apparently healthy infants, and in 47 % of them, it has a persistent nature. The aim of the study: to evaluate the clinical efficiency of antireflux mixture, in which non-digestible polysaccharides — locust bean gum are used as a thickening agent. Materials and methods. The study group consisted of 32 children aged 1 to 12 months with regurgitation. The intensity of regurgitation was assessed in points according to a specially developed and mo-dified scale (G. Vandenplas icnibali, 1993; Shadryn O., 2010. The main group included 20 children, who received antireflux mixture, as a thickening agent, locust bean gum was used; the comparison group — 12 infants, who received antireflux mixture, as a thickening agent, starch was used. Attention was also paid to the “therapeutic position” during feeding: the child’s semi-vertical position during feeding, keeping the child in a vertical position after feeding for at least 10 minutes. Results. The control of the efficiency of the resulting mixtures was monitored by a comparative analysis of the dynamics of complaints and objective data. After 10 days of “treatment” by nutrition and position, in the main group 5 children (25 % did not have regurgitations; in 13 children (65

Crosstalk between Inflammation and ROCK/MLCK Signaling Pathways in Gastrointestinal Disorders with Intestinal Hyperpermeability

Full Text Available The barrier function of the intestine is essential for maintaining the normal homeostasis of the gut and mucosal immune system. Abnormalities in intestinal barrier function expressed by increased intestinal permeability have long been observed in various gastrointestinal disorders such as Crohn’s disease (CD, ulcerative colitis (UC, celiac disease, and irritable bowel syndrome (IBS. Imbalance of metabolizing junction proteins and mucosal inflammation contributes to intestinal hyperpermeability. Emerging studies exploring in vitro and in vivo model system demonstrate that Rho-associated coiled-coil containing protein kinase- (ROCK- and myosin light chain kinase- (MLCK- mediated pathways are involved in the regulation of intestinal permeability. With this perspective, we aim to summarize the current state of knowledge regarding the role of inflammation and ROCK-/MLCK-mediated pathways leading to intestinal hyperpermeability in gastrointestinal disorders. In the near future, it may be possible to specifically target these specific pathways to develop novel therapies for gastrointestinal disorders associated with increased gut permeability.

Full Text Available Because the clinical condition of gastrointestinal dysfunction, including functional dyspepsia, involves tangled combinations of pathologies, there are some cases of insufficient curative efficacy. Thus, traditional herbal medicines (Kampo medicines uniquely developed in Japan are thought to contribute to medical treatment for upper gastrointestinal symptoms. Rikkunshito is a Kampo medicine often used to treat dyspeptic symptoms. Over the past few years, several studies have investigated the efficacy of rikkunshito for dysmotility, for example, upper abdominal complaints, in animals and humans. Rikkunshito ameliorated the decrease in gastric motility and anorexia in cisplatin-treated rats, stress-loaded mice, and selective serotonin reuptake inhibitor-treated rats by enhancing plasma ghrelin levels via serotonin2B/2C receptor antagonism. In addition, rikkunshito ameliorated the decrease in food intake in aged mice and stress-loaded decreased gastric motility via enhanced ghrelin receptor signaling. Several clinical studies revealed that rikkunshito was effective in ameliorating upper gastrointestinal symptoms, including dyspepsia, epigastric pain, and postprandial fullness. In this review, we discuss these studies and propose additional evidence-based research that may promote the clinical use of Kampo medicines, particularly rikkunshito, for treating anorexia and gastrointestinal dysfunction.

Food and symptom generation in functional gastrointestinal disorders: physiological aspects.

The response of the gastrointestinal tract (GIT) to ingestion of food is a complex and closely controlled process, which allows optimization of propulsion, digestion, absorption of nutrients, and removal of indigestible remnants. This review summarizes current knowledge on the mechanisms that control the response of the GIT to food intake. During the cephalic phase, triggered by cortical food-related influences, the GIT prepares for receiving nutrients. The gastric phase is dominated by the mechanical effect of the meal volume. Accumulation of food in the stomach activates tension-sensitive mechanoreceptors, which in turn stimulate gastric accommodation and gastric acid secretion through the intrinsic and vago-vagal reflex pathways. After meal ingestion, the tightly controlled process of gastric emptying starts, with arrival of nutrients in the duodenum triggering negative feedback on emptying and stimulating secretion of digestive enzymes through the neural (mainly vago-vagal reflex, but also intrinsic) and endocrine (release of peptides from entero-endocrine cells) pathways. Several types of specialized receptors detect the presence of all main categories of nutrients. In addition, the gastrointestinal mucosa expresses receptors of the T1R and T2R families (taste receptors) and several members of the transient receptor potential channel family, all of which are putatively involved in the detection of specific tastants in the lumen. Activation of nutrient and taste sensors also activates the extrinsic and intrinsic neural, as well as entero-endocrine, pathways. During passage through the small bowel, nutrients are progressively extracted, and electrolyte-rich liquid intestinal content with non-digestible residue is delivered to the colon. The colon provides absorption of the water and electrolytes, storage of non-digestible remnants of food, aboral propulsion of contents, and finally evacuation through defecation.

Dopamine receptors in human gastrointestinal mucosa

Dopamine is a putative enteric neurotransmitter that has been implicated in exocrine secretory and motility functions of the gastrointestinal tract of several mammalian species including man. This study was designed to determine the presence of dopamine binding sites in human gastric and duodenal mucosa and to describe certain biochemical characteristics of these enteric receptor sites. The binding assay was performed in triplicate with tissue homogenates obtained from healthy volunteers of both sexes using 3 H-dopamine as a ligand. The extent of nonspecific binding was determined in the presence of a 100-fold excess of unlabeled dopamine. Scatchard analysis performed with increasing concentrations of 3 H-dopamine (20-500 nM) revealed a single class of saturable dopamine binding sites in gastric and duodenal mucosa. The results of this report demonstrate the presence of specific dopamine receptors in human gastric and duodenal mucosa. These biochemical data suggest that molecular abnormalities of these receptor sites may be operative in the pathogenesis of important gastrointestinal disorders. 33 references, 2 figures

Celiac disease has been linked to irritable bowel syndrome (IBS)-like symptoms in outpatient clinics. Guidelines recommend that all patients with IBS-like symptoms undergo serologic testing for celiac disease, but there is controversy over whether celiac disease is more prevalent in populations with IBS-like symptoms. We aimed to determine whether positive results from serologic tests for celiac disease are associated with IBS and other functional gastrointestinal disorders (FGIDs) in a large U.S. white population. Validated, self-report bowel disease questionnaires (BDQs) were sent to randomly selected cohorts of Olmsted County, Minnesota residents. In separate protocols, serum samples were collected from more than 47,000 Olmsted County residents without a prior diagnosis of celiac disease; we performed serologic tests for celiac disease on stored serum samples from residents who completed the BDQ. Logistic regression was used to test for the association between serologic markers of celiac disease (positive vs negative) and individual FGIDs. A total of 3202 subjects completed the BDQ and had serum available for testing. IBS was identified in 13.6% of these subjects (95% confidence interval [CI], 12.4%-14.8%), and any gastrointestinal symptom occurred in 55.2% (95% CI, 53.5%-56.9%). The prevalence of celiac disease on the basis of serologic markers was 1.0% (95% CI, 0.7%-1.4%). IBS was less prevalent in patients with celiac disease (3%) than patients without celiac disease (14%), although the difference was not statistically significant (odds ratio, 0.2; 95% CI, 0.03-1.5). Abdominal pain, constipation, weight loss, and dyspepsia were the most frequent symptom groups in subjects who were seropositive for celiac disease, but none of the gastrointestinal symptoms or disorders were significantly associated with celiac disease serology. Symptoms indicative of FGIDs and seropositive celiac disease are relatively common in a U.S. white community. Testing for celiac

Functional Development of the Human Gastrointestinal Tract: Hormone- and Growth Factor-Mediated Regulatory Mechanisms

Directory of Open Access Journals (Sweden)

2004-01-01

Full Text Available The present review focuses on the control of gastrointestinal (GI tract development. The first section addresses the differences in general mechanisms of GI development in humans versus rodents, highlighting that morphogenesis of specific digestive organs and the differentiation of digestive epithelia occur not only at different stages of ontogeny but also at different rates. The second section provides an overview of studies from the author's laboratory at the Université de Sherbrooke pertaining to the development of the human fetal small intestine and colon. While both segments share similar morphological and functional characteristics, they are nevertheless modulated by distinct regulatory mechanisms. Using the organ culture approach, the author and colleagues were able to establish that hormones and growth factors, such as glucocorticoids, epidermal growth factor, insulin and keratinocyte growth factor, not only exert differential effects within these two segments, they can also trigger opposite responses in comparison with animal models. In the third section, emphasis is placed on the functional development of human fetal stomach and its various epithelial cell types; in particular, the glandular chief cells responsible for the synthesis and secretion of gastric enzymes such as pepsinogen-5 and gastric lipase. Bearing in mind that limitations of available cell models have, until now, greatly impeded the comprehension of molecular mechanisms regulating human gastric epithelial cell functions, the last section focuses on new human gastric epithelial cell models recently developed in the author's laboratory. These models comprise a novel primary culture system of human fetal gastric epithelium including, for the first time, functional chief cells, and human gastric epithelium cell lines cloned from the parental NCI-N87 strain. These new cells lines could serve important applications in the study of pathogenic action and epithelial

Functional gastrointestinal symptoms such as abdominal pain, bloating, distension, constipation, diarrhea and flatulence have been noted in patients with irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD). The diversity of symptoms has meant that finding an effective treatment has been challenging with most treatments alleviating only the primary symptom. A novel treatment option for IBS and IBD currently generating much excitement is the low fermentable, oligo-, di-, mono-saccharides and polyol (FODMAP) diet. The aim of this meta-analysis was to determine the evidence of the efficacy of such a diet in the treatment of functional gastrointestinal symptoms. Electronic databases were searched through to March 2015 to identify relevant studies. Pooled odds ratios (ORs) and 95 % confidence intervals were calculated for the effect of a low FODMAP diet on the reduction in IBS [Symptoms Severity Score (SSS)] score and increase in IBS quality of life (QOL) score for both randomized clinical trials (RCTs) and non-randomized interventions using a random-effects model. Six RCTs and 16 non-randomized interventions were included in the analysis. There was a significant decrease in IBS SSS scores for those individuals on a low FODMAP diet in both the RCTs (OR 0.44, 95 % CI 0.25-0.76; I (2) = 35.52, p = 0.00) and non-randomized interventions (OR 0.03, 95 % CI 0.01-0.2; I (2) = 69.1, p = 0.02). In addition, there was a significant improvement in the IBS-QOL score for RCTs (OR 1.84, 95 % CI 1.12-3.03; I (2) = 0.00, p = 0.39) and for non-randomized interventions (OR 3.18, 95 % CI 1.60-6.31; I (2) = 0.00, p = 0.89). Further, following a low FODMAP diet was found to significantly reduce symptom severity for abdominal pain (OR 1.81, 95 % CI 1.13-2.88; I (2) = 0.00, p = 0.56), bloating (OR 1.75, 95 % CI 1.07-2.87; I (2) = 0.00, p = 0.45) and overall symptoms (OR 1.81, 95 % CI 1.11-2.95; I (2) = 0.00, p = 0.4) in the RCTs.

Full Text Available Abstract Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding.

Full Text Available Abstract Background Sleep disturbances are increasingly recognized as a common problem for children and adolescents with chronic pain conditions, but little is known about the prevalence, type, and impact of sleep problems in pediatric functional gastrointestinal disorders (FGIDs. The objectives of the current study were two-fold: 1 to describe the pattern of sleep disturbances reported in a large sample of children and adolescents with FGIDs; and, 2 to explore the impact of sleep by examining the inter-relationships between sleep disturbance, physical symptoms, emotional problems, and functional disability in this population. Methods Over a 3-year period, 283 children aged 8–17 years who were diagnosed with an FGID and a primary caretaker independently completed questionnaires regarding sleep, emotional functioning, physical symptoms, and functional disability during an initial evaluation for chronic abdominal pain at a pediatric tertiary care center. A verbal review of systems also was collected at that time. Descriptive statistics were used to characterize the pattern of sleep disturbances reported, while structural equation modeling (SEM was employed to test theorized meditational relationships between sleep and functional disability through physical and emotional symptoms. Results Clinically significant elevations in sleep problems were found in 45% of the sample, with difficulties related to sleep onset and maintenance being most common. No difference was seen by specific FGID or by sex, although adolescents were more likely to have sleep onset issues than younger children. Sleep problems were positively associated with functional disability and physical symptoms fully mediated this relationship. Emotional symptoms, while associated with sleep problems, evidenced no direct link to functional disability. Conclusions Sleep problems are common in pediatric FGIDs and are associated with functional disability through their impact on physical

To test the hypothesis that children with celiac disease (CD) on gluten-free diet are at increased risk of abdominal pain (AP) associated-functional gastrointestinal disorders (FGIDs). This was a multinational cross-sectional study performed from 2014 to 2015. Patients 4-18 years of age with CD on gluten-free diet for longer than 6 months were recruited from pediatric CD clinics in US and Italy. Control groups included siblings of children with CD (with normal tissue transglutaminase levels) and unrelated controls. Subjects or parents completed the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III. Children (n = 289) were recruited (55% US, 45% Italy): 96 children with CD, 96 sibling controls, and 97 unrelated controls. Chronic AP was present in 30 (30.9%) subjects with CD, 22 (22.7%) sibling controls, and 21 (21.6%) unrelated controls (P = .26 patients with CD vs siblings; P = .18 patients with CD vs unrelated; P = .96 siblings vs unrelated). AP-FGIDs were present in 8 (8.2%) subjects with CD, 8 (8.2%) sibling controls, and 2 (2.1%) unrelated controls (P = 1.00 subjects with CD vs sibling controls; P = .06 subjects with CD vs unrelated controls; P = .06 sibling controls vs unrelated controls). This multinational study evaluated the prevalence of chronic abdominal pain and AP-FGIDs in the pediatric population with CD. We found that subjects with CD and controls have a similar prevalence of chronic AP and AP-FGIDs. This suggests that not all types of gastrointestinal inflammation result in AP-FGIDs in children.

Chronic abdominal pain is a common worldwide problem and known to be associated with psychological problems. This study evaluated the association between abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs), psychological maladjustment and personality traits in adolescents. Adolescents aged 13-18 years were recruited from 5 randomly selected schools in Ampara district of Sri Lanka. AP-FGIDs were diagnosed using Rome III criteria. Translated and validated Rome III questionnaire (Child report form), personality questionnaire (PAQ) and PedsQL (Pediatric Quality of Life) inventory were used in data collection. Written consent was obtained from a parent and assent was obtained from every child recruited. The questionnaire was distributed in an examination setting to ensure confidentiality and privacy. Research assistants were present during data collection to assist on any necessary clarifications. A total of 1697 subjects were recruited [males 779 (45.9%), mean age 15.1 years, SD 1.6 years]. AP-FGIDs were present in 202 (11.9%). Those with AP-FGIDs had significantly higher mean scores for all personality traits (hostility and aggression, negative self-esteem, emotional unresponsiveness, emotional instability and negative world view), except dependency. Affected children had lower scores for all 4 domains of HRQoL (physical, emotional, social and school functioning), compared to controls (p PAQ scores within that of psychological maladjustment (p PAQ negatively correlated with scores obtained for HRQoL (r = - 0.52, p PAQ and lower HRQoL scores (p < 0.05). Adolescents with AP-FGIDs have more psychological maladjustment and abnormal personality traits than healthy controls. Affected adolescents with higher psychological maladjustments have lower HRQoL. Greater psychological maladjustment and lower HRQoL are associated with healthcare seeking behaviour in adolescents with AP-FGIDs.

Lepidium meyenii Walp. (maca) has been utilized in the Andean region because of its edibleness and medicinal value. The aerial parts of maca (APM) were analyzed for protein, total sugar, vitamins, amino acids, and minerals and its characteristic active ingredients at five different growth stages. The results showed the high protein, total sugar, vitamin C, niacin, potassium, and calcium contents of APM. All 17 amino acids and the characteristic active ingredients, namely, macamide, glucosinolates, adenosine, and total saponins, were detected. We examined the effects of maca plant powders on gastric emptying and intestinal propulsion and the levels of serum motilin and gastrin in atropine-treated mice. Benzyl isothiocyanate (BITC) was investigated to identify the potential active material in APM. The results revealed that both maca plant powders and BITC can promote the gastrointestinal prokinetic efficacy. Thus, APM feature potential as new functional vegetable sources.

Diets low in fermentable sugars (low-FODMAP diets) are increasingly adopted by patients with functional gastrointestinal disorders (FGID), but outcome predictors are unclear. To identify factors predictive of an efficacious response to a low-FODMAP diet in FGID patients with fructose or lactose intolerance thereby gaining insights into underlying mechanisms. Fructose and lactose breath tests were performed in FGID patients to determine intolerance (positive symptom score) and malabsorption (increased hydrogen or methane concentrations). Patients with fructose or lactose intolerance consumed a low-FODMAP diet and global adequate symptom relief was assessed after 6-8 weeks and correlated with pre-diet clinical symptoms and breath test results. A total of 81% of 584 patients completing the low-FODMAP diet achieved adequate relief, without significant differences between FGID subgroups or types of intolerance. Univariate analysis yielded predictive factors in fructose intolerance (chronic diarrhoea and pruritus, peak methane concentrations and fullness during breath tests) and lactose intolerance (peak hydrogen and methane concentrations and flatulence during breath tests). Using multivariate analysis, symptom relief was independently and positively predicted in fructose intolerance by chronic diarrhoea [odds ratio (95% confidence intervals): 2.62 (1.31-5.27), P = 0.007] and peak breath methane concentrations [1.53 (1.02-2.29), P = 0.042], and negatively predicted by chronic nausea [0.33 (0.16-0.67), P = 0.002]. No independent predictive factors emerged for lactose intolerance. Adequate global symptom relief was achieved with a low-FODMAP diet in a large majority of functional gastrointestinal disorders patients with fructose or lactose intolerance. Independent predictors of a satisfactory dietary outcome were only seen in fructose intolerant patients, and were indicative of changes in intestinal host or microbiome metabolism. © 2017 John Wiley & Sons Ltd.

Full Text Available Abstract Background Human gastrointestinal mucosa regenerates vigorously throughout life, but the factors controlling cell fate in mature mucosa are poorly understood. GATA transcription factors direct cell proliferation and differentiation in many organs, and are implicated in tumorigenesis. GATA-4 and GATA-6 are considered crucial for the formation of murine gastrointestinal mucosa, but their role in human gastrointestinal tract remains unexplored. We studied in detail the expression patterns of these two GATA factors and a GATA-6 down-stream target, Indian hedgehog (Ihh, in normal human gastrointestinal mucosa. Since these factors are considered important for proliferation and differentiation, we also explored the possible alterations in their expression in gastrointestinal neoplasias. The expression of the carcinogenesis-related protein Indian hedgehog was also investigated in comparison to GATA factors. Methods Samples of normal and neoplastic gastrointestinal tract from children and adults were subjected to RNA in situ hybridization with 33P labelled probes and immunohistochemistry, using an avidin-biotin immunoperoxidase system. The pathological tissues examined included samples of chronic and atrophic gastritis as well as adenomas and adenocarcinomas of the colon and rectum. Results GATA-4 was abundant in the differentiated epithelial cells of the proximal parts of the gastrointestinal tract but was absent from the distal parts. In contrast, GATA-6 was expressed throughout the gastrointestinal epithelium, and in the distal gut its expression was most intense at the bottom of the crypts, i.e. cells with proliferative capacity. Both factors were also present in Barrett's esophagus and metaplasia of the stomach. GATA-6 expression was reduced in colon carcinoma. Ihh expression overlapped with that of GATA-6 especially in benign gastrointestinal neoplasias. Conclusion The results suggest differential but overlapping functions for GATA-4 and

Full Text Available Context: Quality of life (QoL is an important issue in all cancer patients; especially in patients with metastatic cancer. But there is very little information available about QoL in patients with metastatic gastrointestinal cancer. Aims: The aim of this study was to evaluate the quality of life and its associated factors among Iranian patients with metastatic gastrointestinal tract cancer. Materials and Methods: In this cross-sectional study, a total of 250 patients with metastatic gastrointestinal tract cancer were recruited from the one oncology center related to the Mazandaran University of Medical Sciences, Sari, between March 2012 and August 2013. Their QoL was evaluated using the EORTC QLQ-C30 questionnaire (Persian version. Results: In this study, the overall QoL score of patients with gastrointestinal tract cancer was 57.63, which was relatively optimal. There was a statistically significant relationship between symptoms scale and general health status domains of quality of life with age ( P < 0.05. Also, there was a significant association between patients′ gender and their social functioning ( P = 0.017 and also their emotional functioning ( P = 0.015. Conclusions: The findings suggest that in patients with metastatic gastrointestinal cancers, the most affected functions in their QoL were social and emotional functioning which get worse with age. Thus, providing psychological counseling and psychotherapy services to deliver culturally appropriate mental health care and social support for these patients and their families′ which can lead to the improvement of QoL in these patients is strongly recommended.

GASTROINTESTINAL FOOD ALLERGY IN CHILDREN

2017-01-01

Full Text Available In recent years, there has been a significant increase in the prevalence  of food allergies. Pathological conditions associated  with a food intolerance are becoming an increasingly urgent problem of pediatrics. According to different researchers, allergic lesions of the gastrointestinal tract occurs in 25–50% of patients with such common pathology as an allergy to cow's milk proteins. The severity of diseases  associated  with food allergies and their prognosis  depend largely on early diagnosis and adequate treatment. Difficulties and errors  in the diagnosis  of gastrointestinal  food allergies  are associated  with both subjective  and objective  reasons,  primarily due to the fact that gastrointestinal  reactions to food are often delayed and non-IgE-mediated. The article describes clinical forms of gastrointestinal food allergy according to the existing classification. Diagnostic algorithms and modern approaches  to differential diagnosis of disease based on evidence-based  medicine and corresponding to international consensus papers are given.

Full Text Available Abstract Background Studies on gastrointestinal symptoms, dysfunctions, and neurological disorders in systemic scleroderma are lacking so far. Methods Thirty-eight scleroderma patients (34 limited, 4 diffuse, 60 healthy controls and 68 dyspeptic controls were scored for upper and lower gastrointestinal symptoms (dyspepsia, bowel habits, gastric and gallbladder emptying to liquid meal (functional ultrasonography and small bowel transit (H2-breath test. Autonomic nerve function was assessed by cardiovascular tests. Results The score for dyspepsia (mainly gastric fullness was greater in scleroderma patients than healthy controls, but lower than dyspeptic controls who had multiple symptoms, instead. Scleroderma patients with dyspepsia had a longer disease duration. Fasting antral area and postprandial antral dilatation were smaller in scleroderma patients than dyspeptic and healthy controls. Gastric emptying was delayed in both scleroderma patients (particularly in those with abnormal dyspeptic score and dyspeptic controls, who also showed a larger residual area. Despite gallbladder fasting and postprandial volumes were comparable across the three groups, gallbladder refilling appeared delayed in dyspeptic controls and mainly dependent on delayed gastric emptying in scleroderma. Small intestinal transit was also delayed in 74% of scleroderma and 66% of dyspeptic controls. Bowel habits were similar among the three groups. Autonomic neuropathy was not associated with dyspepsia, gastric and gallbladder motility and small intestinal transit. Conclusion In scleroderma patients dyspepsia (mainly gastric fullness, restricted distension of the gastric antrum and diffuse gastrointestinal dysmotility are frequent features. These defects are independent from the occurrence of autonomic neuropathy.

Purpose: To analyze clinical and dosimetric factors associated with change in renal function in patients with gastrointestinal malignancies after chemoradiation to the abdomen. Methods and Materials: A retrospective review of 164 patients with gastrointestinal malignancies treated between 2002 and 2007 was conducted to evaluate change in renal function after concurrent chemotherapy and three-dimensional conformal abdominal radiotherapy (RT). Laboratory and biochemical endpoints were determined before RT and after RT at 6-month intervals. Factors assessed included smoking, diabetes, hypertension, blood urea nitrogen, creatinine, creatinine clearance (CrCl), chemotherapy, and dose-volume parameters. Renal toxicity was assessed by decrease in CrCl and scored using the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer late radiation morbidity scoring schema. Results: Of 164 patients, 63 had clinical and dosimetric data available. Median follow-up was 17.5 months. Creatinine clearance declined from 98.46 mL/min before RT to 74.20 mL/min one year after chemoradiation (p 10 ), and mean kidney dose were significantly associated with development of Grade ≥2 renal complications at 1 year after chemoradiation (p = 0.0025, 0.0170, and 0.0095, respectively). Conclusions: We observed correlation between pre-RT CrCl, V 10 , and mean kidney dose and decline in CrCl 1 year after chemoradiation. These observations can assist in treatment planning and renal dose constraints in patients receiving chemotherapy and abdominal RT and may help identify patients at increased risk for renal complications.

Objective: To determine the effectiveness and advantage of small amount of barium in the measurement of gastrointestinal transmission function in comparison with radio-opaque pallets. Methods: Protocal 1: 8 healthy volunteers (male 6, female 2) with average age 40 ± 6.1 were subjected to the examination of radio-opaque pellets and small amount of barium with the interval of 1 week. Protocol 2: 30 healthy volunteers in group 1 (male 8, female 22) with average age 42.5 ± 8.1 and 50 patients with chronic functional constipation in group 2 (male 11, female 39) with average age 45.7 ± 7.8 were subjected to the small amount of barium examination. The small amount of barium was made by 30 g barium dissolved in 200 ml breakfast. After taking breakfast which contains barium, objectives were followed with abdominal X-ray at 4, 8, 12, 24, 48, 72, 96 h until the barium was evacuated totally. Results: Small amount of barium presented actual chyme or stool transit. The transit time of radio-opaque pallets through the whole gastrointestinal tract was significantly shorter than that of barium (37 ± 8 h vs. 47 ± 10 h, P < 0.05) in healthy people. The transit times of barium in constipation patients were markedly prolonged in colon (61.1 ± 22 vs. 37.3 ± 11, P < 0.01) and rectum (10.8 ± 3.7 vs. 2.3 ± 0.8 h, P < 0.01) compared with unconstipated volunteers. Transit times in individual gastrointestinal segments were also recorded by using small amount of barium, which allowed identifying the subtypes of constipation. Conclusion: The small amount barium examination is a convenient and low cost method to provide the most useful and reliable information on the transmission function of different gastrointestinal segments and able to classify the subtypes of slow transit constipation.

Jarosław Koza

2017-12-01

Description of the current knowledge and conclusions. Serotonin is responsible for some symptoms of carcinoid syndrome. It is the result of higher 5-hydroxytryptamine content in the body. Moreover disrupted serotonin system is found in different gastrointestinal disorders e.g. in gastroesophageal reflux disease, functional heartburn, hypersensitive esophagus, functional dyspepsia, irritable bowel syndrome (both diarrhoea predominant and constipation predominant as well as in inflammatory bowel diseases. Knowledge of changed mechanisms in particular diseases facilitates the optimal choice of treatment. Drugs affecting the serotonin system in gastroenterological clinical practice are useful especially in the case of abnormalities in the brain - gut axis.

The purpose of this study is to describe the sonographic appearance of lymphoma of the gastrointestinal tract in dogs. A retrospective review was conducted and patients with gastrointestinal lymphoma diagnosed by histopathology (including immunohistochemistry, where available) or cytology that had an abdominal ultrasound were included. Four of 15 (26·7%) cases with histopathologically confirmed lymphoma exhibited no sonographic abnormalities. In the dogs with sonographic abnormalities, features including intestinal wall thickness and the presence or absence of wall layering were highly variable. Clinical signs pertaining to the gastrointestinal tract were also unreliable markers of gastrointestinal lymphoma, with weight loss, vomiting, and diarrhoea being uncommon presenting complaints; intestinal obstruction was not present in any patient. The sonographic appearance of gastrointestinal lymphoma in dogs is non-specific. Gastrointestinal lymphoma in dogs should be maintained as a differential diagnosis despite a sonographically normal appearing bowel. © 2013 British Small Animal Veterinary Association.

Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

Pain-related functional gastrointestinal disorders (P-FGIDs; eg, irritable bowel syndrome) are highly prevalent in children and associated with low quality of life, anxiety, and school absence. Treatment options are scarce, and there is a need for effective and accessible treatments. Internet-delivered cognitive behavior therapy (Internet-CBT) based on exposure exercises is effective for adult and adolescent irritable bowel syndrome, but it has not been evaluated for younger children. The objective of this study was to assess acceptability, feasibility, and potential clinical efficacy of Internet-CBT for children with P-FGIDs. This was a feasibility study with a within-group design. We included 31 children aged 8-12 years and diagnosed with P-FGID, according to the ROME III criteria. Mean duration of abdominal symptoms at baseline was 3.8 years (standard deviation [SD] 2.6). The treatment was therapist-guided and consisted of 10 weekly modules of exposure-based Internet-CBT. The children were instructed to provoke abdominal symptoms in a graded manner and to engage in previously avoided activities. The parents were taught to decrease their attention to their children's pain behaviors and to reinforce and support their work with the exposures. Assessments included treatment satisfaction, subjective treatment effect, gastrointestinal symptoms, quality of life, pain intensity, anxiety, depression, and school absence. Data were collected at pretreatment, posttreatment, and 6-month follow-up. Means, standard errors (SEs), and Cohen d effect sizes were estimated based on multi-level linear mixed models. Most children 25/31 (81%) completed 9 or 10 of the 10 treatment modules. Almost all children, 28/31 (90%), reported that the treatment had helped them to deal more effectively with their symptoms, and 27/31 (87%) children declared that their symptoms had improved during the treatment. Assessments from the parents were in accordance with the children's reports. No child or

Full Text Available Abstract Postprandial lipaemia may lead to an increase in oxidative stress, inducing endothelial dysfunction. Exercise can slow gastric emptying rates, moderating postprandial lipaemia. The purpose of this study was to determine if moderate exercise, prior to fat ingestion, influences gastrointestinal transit, lipaemia, oxidative stress and arterial wall function. Eight apparently healthy males (age 23.6 ± 2.8 yrs; height 181.4 ± 8.1 cm; weight 83.4 ± 16.2 kg; all data mean ± SD participated in the randomised, crossover design, where (i subjects ingested a high-fat meal alone (control, and (ii ingested a high-fat meal, preceded by 1 h of moderate exercise. Pulse Wave Velocity (PWV was examined at baseline, post-exercise, and in the postprandial period. Gastric emptying was measured using the 13C-octanoic acid breath test. Measures of venous blood were obtained prior to and following exercise and at 2, 4 and 6 hours post-ingestion. PWV increased (6.5 ± 1.9 m/sec at 2 (8.9 ± 1.7 m/sec and 4 hrs (9.0 ± 1.6 m/sec post-ingestion in the control group (time × group interaction, P

We investigated the relationship between personality traits and response to treatment with the tetracyclic antidepressant mianserin or placebo in patients with functional gastrointestinal disorder (FGD) without psychopathology. Forty-eight patients completed the Buss-Durkee Hostility Inventory, Neuroticism Extroversion Openness -Personality Inventory (NEO-PI), and Eysenck Personality Questionnaire (EPQ), neuroticism + lie subscales, before they were consecutively allocated to a 7-week double-blind treatment study with mianserin or placebo. Treatment response to pain and target symptoms were recorded daily with the Visual Analogue Scale and Clinical Global Improvement Scale at every visit. A low level of neuroticism and little concealed aggressiveness predicted treatment outcome with the antidepressant drug mianserin in non-psychiatric patients with FGD. Inversely, moderate to high neuroticism and marked concealed aggressiveness predicted poor response to treatment. These findings were most prominent in women. Personality traits were better predictors of treatment outcome than serotonergic sensitivity assessed with the fenfluramine test. Assessment of the personality traits negativism, irritability, aggression, and neuroticism may predict response to drug treatment of FGD even when serotonergic sensitivity is controlled for. If confirmed in future studies, the findings point towards a more differential psychopharmacologic treatment of FGD.

Full Text Available Background: Patients with functional gastrointestinal disorders (FGIDs may use specific coping strategies. We intend to provide a mediating role of the relationship between pain (intensity and acceptance, cognitive emotion regulation strategies, and negative emotions in patients with FGIDs. Materials and Methods: Participants were 176 inpatients, all experiencing significant FGIDs symptomatology as confirmed by gastroenterologists. Patients completed data on cognitive emotion regulation questionnaire, short form of depression, anxiety, stress scale, chronic pain acceptance questionnaire-revised, and pain intensity scale. Data were analyzed using structural equation modeling method. Results: The pain intensity had significantly direct effect on cognitive emotion regulation strategies and indirect effect on negative emotions. Besides, the mediating role of negative emotions in the relationship between the strategies and pain acceptance were supported, whereas indirect relationships between pain intensity and acceptance through cognitive strategies were not confirmed. Conclusion: The results of the study emphasize the role of pain intensity in the development of negative emotions through cognitive strategies and the role of the strategies in pain acceptance through negative emotions. In fact, cognitive strategies to be related to pain and emotions.

Kanaly, Travis; Shaheen, Nicholas J; Vaughn, Bradley V

2009-11-01

The dynamic interplay of the digestive system and sleep is an excellent example of brain-body interaction. New advances in measuring techniques provide an opportunity to evaluate physiology that is dependent upon the sleep/wake state or circadian rhythm and potentially differentiate between normal and pathological conditions. Sleep-related changes in gastrointestinal physiology create vulnerabilities to digestive issues such as reflux, whereas disorders such as duodenal ulcers raise the importance of circadian variations in digestive system function. Advances in the area of normal sleep physiology have furthered our understanding of the underlying cause of irritable bowel syndrome, and the mechanisms by which sleep disruption may aggravate inflammatory bowel disease. Additionally, important early work has shown that the treatment of digestive disorders such as reflux can improve sleep quality just as the improvement in sleep may aid in the treatment of digestive disorders. For the clinician, these forward steps in our knowledge mark the start of an era in which understanding the effects of the sleep/wake state and circadian rhythms on gastrointestinal physiology promise to yield novel diagnostic and therapeutic opportunities.

Gastrointestinal Hormones Induced the Birth of Endocrinology.

Science.gov (United States)

Wabitsch, Martin

2017-01-01

The physiological studies by British physiologists William Maddock Bayliss and Ernest Henry Starling, at the beginning of the last century, demonstrated the existence of specific messenger molecules (hormones) circulating in the blood that regulate the organ function and physiological mechanisms. These findings led to the concept of endocrinology. The first 2 hormones were secretin, discovered in 1902, and gastrin, discovered in 1905. Both hormones that have been described are produced in the gut. This chapter summarizes the history around the discovery of these 2 hormones, which is perceived as the birth of endocrinology. It is noteworthy that after the discovery of these 2 gastrointestinal hormones, many other hormones were detected outside the gut, and thereafter gut hormones faded from both the clinical and scientific spotlight. Only recently, the clinical importance of the gut as the body's largest endocrine organ producing a large variety of hormones has been realized. Gastrointestinal hormones are essential regulators of metabolism, growth, development and behavior and are therefore the focus of a modern pediatric endocrinologist. © 2017 S. Karger AG, Basel.

Gastrointestinal food allergies.

Science.gov (United States)

Heine, Ralf G

2015-01-01

Gastrointestinal food allergies present during early childhood with a diverse range of symptoms. Cow's milk, soy and wheat are the three most common gastrointestinal food allergens. Several clinical syndromes have been described, including food protein-induced enteropathy, proctocolitis and enterocolitis. In contrast with immediate, IgE-mediated food allergies, the onset of gastrointestinal symptoms is delayed for at least 1-2 hours after ingestion in non-IgE-mediated allergic disorders. The pathophysiology of these non-IgE-mediated allergic disorders is poorly understood, and useful in vitro markers are lacking. The results of the skin prick test or measurement of the food-specific serum IgE level is generally negative, although low-positive results may occur. Diagnosis therefore relies on the recognition of a particular clinical phenotype as well as the demonstration of clear clinical improvement after food allergen elimination and the re-emergence of symptoms upon challenge. There is a significant clinical overlap between non-IgE-mediated food allergy and several common paediatric gastroenterological conditions, which may lead to diagnostic confusion. The treatment of gastrointestinal food allergies requires the strict elimination of offending food allergens until tolerance has developed. In breast-fed infants, a maternal elimination diet is often sufficient to control symptoms. In formula-fed infants, treatment usually involves the use an extensively hydrolysed or amino acid-based formula. Apart from the use of hypoallergenic formulae, the solid diets of these children also need to be kept free of specific food allergens, as clinically indicated. The nutritional progress of infants and young children should be carefully monitored, and they should undergo ongoing, regular food protein elimination reassessments by cautious food challenges to monitor for possible tolerance development. © 2015 S.

The objective of this study was to develop a pediatric measure of chronic nausea severity, the Nausea Severity Scale (NSS), and evaluate its reliability and validity in youth with abdominal pain-related functional gastrointestinal disorders (AP-FGID). Pediatric patients (aged 11⁻17 years-old, n = 236) presenting to an outpatient clinic for evaluation of abdominal pain completed the NSS, Children's Somatization Inventory (CSI), Functional Disability Inventory (FDI), Abdominal Pain Index (API), Patient-Report Outcomes Measurement Information System (PROMIS), Anxiety and Depression Scales and the Pediatric Rome III Questionnaire for FGIDs. The NSS demonstrated good concurrent, discriminant, and construct validity, as well as good internal consistency. One-third (34%) of AP-FGID patients reported experiencing nausea "most" or "every day" in the previous two weeks. The severity of nausea was higher in females than males and correlated significantly with the severity of somatic symptoms, functional disability, anxiety, and depression. The NSS is a valid and reliable measure of nausea in children with AP-FGID.

Anemia and iron deficiency in gastrointestinal and liver conditions

Iron deficiency anemia (IDA) is associated with a number of pathological gastrointestinal conditions other than inflammatory bowel disease, and also with liver disorders. Different factors such as chronic bleeding, malabsorption and inflammation may contribute to IDA. Although patients with symptoms of anemia are frequently referred to gastroenterologists, the approach to diagnosis and selection of treatment as well as follow-up measures is not standardized and suboptimal. Iron deficiency, even without anemia, can substantially impact physical and cognitive function and reduce quality of life. Therefore, regular iron status assessment and awareness of the clinical consequences of impaired iron status are critical. While the range of options for treatment of IDA is increasing due to the availability of effective and well-tolerated parenteral iron preparations, a comprehensive overview of IDA and its therapy in patients with gastrointestinal conditions is currently lacking. Furthermore, definitions and assessment of iron status lack harmonization and there is a paucity of expert guidelines on this topic. This review summarizes current thinking concerning IDA as a common co-morbidity in specific gastrointestinal and liver disorders, and thus encourages a more unified treatment approach to anemia and iron deficiency, while offering gastroenterologists guidance on treatment options for IDA in everyday clinical practice.

Gastrointestinal stromal tumours (GISTs) represent a heterogeneous group of tumours of mesenchymal origin characterized by gain-of-function mutations in KIT or PDGFRA of the type III receptor tyrosine kinase family. Although mutations in either receptor are thought to drive an early oncogenic event through similar pathways, two previous studies reported the mutation-specific gene expression profiles. However, their further conclusions were rather discordant. To clarify the molecular characteristics of differentially expressed genes according to GIST receptor mutations, we combined microarray-based analysis with detailed functional annotations. Total RNA was isolated from 29 frozen gastric GISTs and processed for hybridization on GENECHIP ® HG-U133 Plus 2.0 microarrays (Affymetrix). KIT and PDGFRA were analyzed by sequencing, while related mRNA levels were analyzed by quantitative RT-PCR. Fifteen and eleven tumours possessed mutations in KIT and PDGFRA, respectively; no mutation was found in three tumours. Gene expression analysis identified no discriminative profiles associated with clinical or pathological parameters, even though expression of hundreds of genes differentiated tumour receptor mutation and expression status. Functional features of genes differentially expressed between the two groups of GISTs suggested alterations in angiogenesis and G-protein-related and calcium signalling. Our study has identified novel molecular elements likely to be involved in receptor-dependent GIST development and allowed confirmation of previously published results. These elements may be potential therapeutic targets and novel markers of KIT mutation status

Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia. PMID:28072728

Connecting the Mind–Body Split: Understanding the Relationship between Symptoms and Emotional Well-Being in Chronic Pain and Functional Gastrointestinal Disorders

2017-12-01

Full Text Available Paediatric chronic conditions, e.g., chronic pain and functional gastrointestinal disorders, are commonly diagnosed, with fatigue, pain and abdominal discomfort the most frequently reported symptoms across conditions. Regardless of whether symptoms are connected to an underlying medical diagnosis or not, they are often associated with an increased experience of psychological distress by both the ill child and their parents. While pain and embarrassing symptoms can induce increased distress, evidence is also accumulating in support of a reciprocal relationship between pain and distress. This reciprocal relationship is nicely illustrated in the fear avoidance model of pain, which has recently been found to be applicable to childhood pain experiences. The purpose of this article is to illustrate how mind (i.e., emotions and body (i.e., physical symptoms interact using chronic pain and gastrointestinal disorders as key examples. Despite the evidence for the connection between mind and body, the mind–body split is still a dominant position for families and health care systems, as evidenced by the artificial split between physical and mental health care. In a mission to overcome this gap, this article will conclude by providing tools on how the highlighted evidence can help to close this gap between mind and body.

The expanding regulatory universe of p53 in gastrointestinal cancer.

Science.gov (United States)

Fesler, Andrew; Zhang, Ning; Ju, Jingfang

2016-01-01

Tumor suppresser gene TP53 is one of the most frequently deleted or mutated genes in gastrointestinal cancers. As a transcription factor, p53 regulates a number of important protein coding genes to control cell cycle, cell death, DNA damage/repair, stemness, differentiation and other key cellular functions. In addition, p53 is also able to activate the expression of a number of small non-coding microRNAs (miRNAs) through direct binding to the promoter region of these miRNAs.  Many miRNAs have been identified to be potential tumor suppressors by regulating key effecter target mRNAs. Our understanding of the regulatory network of p53 has recently expanded to include long non-coding RNAs (lncRNAs). Like miRNA, lncRNAs have been found to play important roles in cancer biology.  With our increased understanding of the important functions of these non-coding RNAs and their relationship with p53, we are gaining exciting new insights into the biology and function of cells in response to various growth environment changes. In this review we summarize the current understanding of the ever expanding involvement of non-coding RNAs in the p53 regulatory network and its implications for our understanding of gastrointestinal cancer.

Gastrointestinal submucosal tumors originate from submucosal histologic structures such as muscles, lymph nodes, nerves, fibers and vessels. Most patients are asymptomatic. Lesions that are large or ulcerated may cause abdominal pain or upper gastrointestinal bleeding, and those that grow intraluminally sometimes become pedunculated and occasionally prolapse to cause intussusception. Adenocarcinoma is the most common primary gastrointestinal tumor, accounting for approximately 90-95% of such lesions, while submucosal tumors account for approximately 2-6% of all gastrointestinal tumors. Because their overlying mucosa appears normal, submucosal tumors age after difficult to visualize endoscopically, and for this reason, barium studies or CT scans are helpful for diagnosis. In this paper, variable CT and barium study findings of the different types of gastrointestinal submucosal tumor are demonstrated, and a brief discussion of the respective disease entities is included.

Gluten is a crucial functional component of bread, but the effect of increasing gluten content on gastrointestinal (GI) function remains uncertain. Our aim was to investigate the effect of increasing gluten content on GI function and symptoms in healthy participants using the unique capabilities of MRI. A total of twelve healthy participants completed this randomised, mechanistic, open-label, three-way crossover study. On days 1 and 2 they consumed either gluten-free bread (GFB), or normal gluten content bread (NGCB) or added gluten content bread (AGCB). The same bread was consumed on day 3, and MRI scans were performed every 60 min from fasting baseline up to 360 min after eating. The appearance of the gastric chime in the images was assessed using a visual heterogeneity score. Gastric volumes, the small bowel water content (SBWC), colonic volumes and colonic gas content and GI symptoms were measured. Fasting transverse colonic volume after the 2-d preload was significantly higher after GFB compared with NGCB and AGCB with a dose-dependent response (289 (SEM 96) v. 212 (SEM 74) v. 179 (SEM 87) ml, respectively; P=0·02). The intragastric chyme heterogeneity score was higher for the bread with increased gluten (AGCB 6 (interquartile range (IQR) 0·5) compared with GFB 3 (IQR 0·5); P=0·003). However, gastric half-emptying time was not different between breads nor were study day GI symptoms, postprandial SBWC, colonic volume and gas content. This MRI study showed novel mechanistic insights in the GI responses to different breads, which are poorly understood notwithstanding the importance of this staple food.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal system. These types of tumors originate from any part of the tract as well as from the intestine, colon, omentum, mesentery or retroperitoneum. GIST is a rare tumor compared to other types of tumors, accounting for less than 1% of all gastrointestinal tumors. A 56-year-old male patient was hospitalized due to an upper gastrointestinal hemorrhage and the start of abdominal pain on the same day. In the upper gastrointestinal endoscopy that was performed, a solitary mass was found in the second section of the duodenum and a blood vessel (Forrest type 2a) was seen. The extent and location of the mass was detected by abdominal tomography. After hemodynamic recovery, a Whipple procedure was performed without any complications. A subsequent histopathological examination detected a c-kit-positive (CD117) pancreatic GIST with high mitotic index. The most effective treatment method for GISTs is surgical resection. In patients with a head of pancreatic GIST, the Whipple procedure can be used more safely and effectively.

Incidence of gastrointestinal cancer rises with age. In spite of this fact, older patients are underrepresented in clinical trials. We need to take into account several variables prior to selection of therapy in these patients. These are physiologic aging processes, comorbidities, functional and cognitive status. There are several assessment tools in geriatric population – the most used is comprehensive geriatric assessment (CGA). A close cooperation with geriatrician is useful before starting cancer treatment. This article reviews treatment algorithms in selected malignancies of GI tract in geriatric patients. (author)

Functional gastrointestinal disorders (FGD) are common among children, but little is known regarding their prevalence in developing countries. We assessed the prevalence of abdominal pain-predominant FGD, in addition to the predisposing factors and symptomatology, in Sri Lankan children. A cross-sectional survey was conducted among a randomly selected group of 10- to 16-year-olds in 8 randomly selected schools in 4 provinces in Sri Lanka. A validated, self-administered questionnaire was completed by children independently in an examination setting. FGD were diagnosed using Rome III criteria. A total of 2180 questionnaires were distributed and 2163 (99.2%) were included in the analysis (1189 [55%] boys, mean age 13.4 years, standard deviation 1.8 years). Of them, 270 (12.5%) had at least 1 abdominal pain-predominant FGD. Irritable bowel syndrome (IBS) was seen in 107 (4.9%), functional dyspepsia in 54 (2.5%), functional abdominal pain in 96 (4.4%), and abdominal migraine (AM) in 21 (1.0%) (2 had AM and functional dyspepsia, 6 had AM and IBS). Extraintestinal symptoms were more common among affected children (P Abdominal pain-predominant FGD were higher in girls and those exposed to stressful events (P Abdominal pain-predominant FGD affects 12.5% of children ages 10 to 16 years and constitutes a significant health problem in Sri Lanka.

Children with cerebral palsy (CP) often demonstrate abnormal feeding behaviours, leading to reduced food consumption and malnutrition. Moreover, most of them present with gastrointestinal disorders, such as gastroesophageal reflux disease (GERD) and/or chronic constipation (CC), and poor motor function rehabilitation. The aim of our study was to assess the possible relationship between malnutrition and gastrointestinal problems and to evaluate the role of nutrition on their gross motor abilities in a population of children with CP and mental retardation. Twenty-one consecutive children (10 boys; mean age: 5.8+/-4.7 years; range: 1-14 years) with CP and severe mental retardation. Nutritional assessment included the measurement of body mass index (BMI=W/H2), fat body mass (FBM) and fat free mass (FFM). Children with symptoms suggesting GERD underwent prolonged 24h intraesophageal pH monitoring and/or upper GI endoscopy with biopsies before and after a 6 months of pharmaceutical (omeprazole) and nutritional (20% increment of daily caloric intake) treatments. The motor function was evaluated by "The Gross Motor Function Measure" (GMFM) before and after the 6 months on nutritional rehabilitation. BMI for age was or=25 degrees percentile, five of nine (55.5%) patients had persistent GERD when they were taken off the medication. Malnutrition and gastrointestinal disorders are very common in children with cerebral palsy. Improved nutritional status, particularly fat free mass gain, appears to have an impact on motor function in children with CP.

Gastrointestinal conditions are a less common cause of sudden unexpected death when compared to other conditions such as cardiovascular conditions, but they are equally important. Various congenital and acquired gastrointestinal conditions that have resulted in sudden unexpected death are discussed. The possible lethal mechanisms behind each condition, along with any associated risk factors or secondary diseases, have been described. Through this article, we aim to highlight the need for physicians to prevent death in such conditions by ensuring that subclinical cases are diagnosed correctly before it is too late and by providing timely and efficacious treatment to the patient concerned. In addition, this review would certainly benefit the forensic pathologist while dealing with cases of sudden unexpected death due to gastrointestinal causes. This article is a review of the major gastrointestinal causes of sudden unexpected death. In addition, related fatal cases encountered occasionally in forensic autopsy practice are also included. There are several unusual and rare causes of life-threatening gastrointestinal bleeding that may lead to sudden unexpected death to cover all the entities in detail. Nevertheless, this article is a general guide to the topic of gastrointestinal causes of sudden unexpected death.

Abnormal gastrointestinal endocrine cells in patients with diabetes type 1: relationship to gastric emptying and myoelectrical activity.

Science.gov (United States)

El-Salhy, M; Sitohy, B

2001-11-01

Gastrointestinal symptoms in patients with diabetes are believed to be caused by gastrointestinal dysmotility and secretion/absorption disturbances, and the gut endocrine cells play an important part in regulating these two functions. Studies on animal models of human diabetes type I revealed abnormality in these cells, but it is unknown whether abnormality also occurs in patients with diabetes. Eleven patients with long duration of diabetes type I and organ complications, as well as gastrointestinal symptoms, were studied. Endocrine cells in different segments of the gastrointestinal tract were detected by immunocytochemistry and quantified by computerized image analysis. Gastric emptying was measured by scintigraphy and gastric myoelectric activity was determined by electrogastrography. An abnormal density of gastrointestinal endocrine cells was found in patients with diabetes. This abnormality occurred in all segments of the upper and lower gastrointestinal tract investigated, and included most of the endocrine cell types. The patients showed delayed gastric emptying, which correlated closely with the acute glucose level, but did not correlate with HbA1c. Gastric emptying also correlated closely with the density of duodenal serotonin and secretin cells. The patients exhibited bradygastrias and tachygastrias. These dysrhythmias, however, did not differ significantly from controls. The endocrine cells are the anatomical units responsible for the production of gut hormones, and the change in their density would reflect a change in the capacity of producing these hormones. The abnormality in density of the gastrointestinal endocrine cells may contribute to the development of gastrointestinal dysmotility and the symptoms encountered in patients with diabetes.

PPARs Signaling and Cancer in the Gastrointestinal System

Full Text Available Nowadays, the study of the peroxisome proliferators activated receptors (PPARs as potential targets for cancer prevention and therapy has gained a strong interest. From a biological point of view, the overall responsibility of PPARs in cancer development and progression is still controversial since several studies report both antiproliferative and tumor-promoting actions for these signaling molecules in human cancer cells and animal models. In this paper, we discuss PPARs functions in the context of different types of gastrointestinal cancer.

Microbiota alterations in acute and chronic gastrointestinal inflammation of cats and dogs

Honneffer, Julia B; Minamoto, Yasushi; Suchodolski, Jan S

2014-01-01

The intestinal microbiota is the collection of the living microorganisms (bacteria, fungi, protozoa, and viruses) inhabiting the gastrointestinal tract. Novel bacterial identification approaches have revealed that the gastrointestinal microbiota of dogs and cats is, similarly to humans, a highly complex ecosystem. Studies in dogs and cats have demonstrated that acute and chronic gastrointestinal diseases, including inflammatory bowel disease (IBD), are associated with alterations in the small intestinal and fecal microbial communities. Of interest is that these alterations are generally similar to the dysbiosis observed in humans with IBD or animal models of intestinal inflammation, suggesting that microbial responses to inflammatory conditions of the gut are conserved across mammalian host types. Studies have also revealed possible underlying susceptibilities in the innate immune system of dogs and cats with IBD, which further demonstrate the intricate relationship between gut microbiota and host health. Commonly identified microbiome changes in IBD are decreases in bacterial groups within the phyla Firmicutes and Bacteroidetes, and increases within Proteobacteia. Furthermore, a reduction in the diversity of Clostridium clusters XIVa and IV (i.e., Lachnospiraceae and Clostridium coccoides subgroups) are associated with IBD, suggesting that these bacterial groups may play an important role in maintenance of gastrointestinal health. Future studies are warranted to evaluate the functional changes associated with intestinal dysbiosis in dogs and cats. PMID:25469017

Full Text Available Introduction : Accurate diagnosis of subepithelial lesions (SELs in the gastrointestinal tract depends on a variety of methods: endoscopy, endoscopic ultrasound and different types of biopsy. Making an error-free diagnosis is vital for the subsequent application of an appropriate treatment. Aim: To evaluate the efficacy of deep biopsy via the endoscopic submucosal dissection (ESD technique for SELs in the upper gastrointestinal tract. Material and methods: It was a case series study. Deep biopsy via the ESD technique was completed in 38 patients between November 2012 and October 2014. Thirty-eight SELs in the upper gastrointestinal tract of varying size (very small ≤ 1 cm, small 1–2 cm and large ≥ 2 cm by means of the ESD technique after an incision with an electrosurgical knife of the overlying layers and revealing a small part of the lesion were biopsied under direct endoscopic view. Results: Deep biopsy via the ESD technique was diagnostic in 28 of 38 patients (73.3%; 95% CI: 59.7–89.7%. The diagnostic yield for SELs with a clear endophytic shape increased to 91.3%. An evident endophytic appearance of a subepithelial lesion, the mean number of biopsied samples (6.65 ±1.36 and the total size in length of all samples per case (19.88 ±8.07 mm were the main criteria influencing the positiveness of deep biopsy in the diagnostic group compared to the nondiagnostic one (p = 0.001; p = 0.025; p = 0.008. Conclusions : Deep biopsy via the ESD technique is an effective and safe method for the diagnosis of SELs especially with a clear endophytic appearance in a large number of biopsied samples.

[Gastrointestinal bleeding--concepts of surgical therapy in the upper gastrointestinal tract].

Science.gov (United States)

Knoefel, W T; Rehders, A

2006-02-01

Bleeding of the upper gastrointestinal tract is the main symptom of a variety of possible conditions and still results in considerable mortality. Endoscopy is the first diagnostic modality, enabling rapid therapeutic intervention. In case of intractable or relapsing bleeding, surgery is often inevitable. However, emergency operations result in significantly higher mortality rates. Therefore the option of early elective surgical intervention should be considered for patients at increased risk of relapsing bleeding. If bleeding is symptomatic due to a complex underlying condition such as hemosuccus pancreaticus or hemobilia, angiography is now recognized as the definitive investigation. Angiographic hemostasis can be achieved in most cases. Due to the underlying condition, surgical management still remains the mainstay in treating these patients. This paper reviews surgical strategy in handling upper gastrointestinal bleeding.

Cardioprotective aspirin users and their excess risk of upper gastrointestinal complications.

Hernández-Díaz, Sonia; García Rodríguez, Luis A

2006-09-20

To balance the cardiovascular benefits from low-dose aspirin against the gastrointestinal harm caused, studies have considered the coronary heart disease risk for each individual but not their gastrointestinal risk profile. We characterized the gastrointestinal risk profile of low-dose aspirin users in real clinical practice, and estimated the excess risk of upper gastrointestinal complications attributable to aspirin among patients with different gastrointestinal risk profiles. To characterize aspirin users in terms of major gastrointestinal risk factors (i.e., advanced age, male sex, prior ulcer history and use of non-steroidal anti-inflammatory drugs), we used The General Practice Research Database in the United Kingdom and the Base de Datos para la Investigación Farmacoepidemiológica en Atención Primaria in Spain. To estimate the baseline risk of upper gastrointestinal complications according to major gastrointestinal risk factors and the excess risk attributable to aspirin within levels of these factors, we used previously published meta-analyses on both absolute and relative risks of upper gastrointestinal complications. Over 60% of aspirin users are above 60 years of age, 4 to 6% have a recent history of peptic ulcers and over 13% use other non-steroidal anti-inflammatory drugs. The estimated average excess risk of upper gastrointestinal complications attributable to aspirin is around 5 extra cases per 1,000 aspirin users per year. However, the excess risk varies in parallel to the underlying gastrointestinal risk and might be above 10 extra cases per 1,000 person-years in over 10% of aspirin users. In addition to the cardiovascular risk, the underlying gastrointestinal risk factors have to be considered when balancing harms and benefits of aspirin use for an individual patient. The gastrointestinal harms may offset the cardiovascular benefits in certain groups of patients where the gastrointestinal risk is high and the cardiovascular risk is low.

2013-01-01

Historically, the tumors that were morphologically different and clinically less agressive than the more common gastrointestinal adenocarcinomas were clasified under carcinoid tumors. However, the development of molecular biology tehniques revealed the heterogeneity of these tumors on cellular and subcellular level and ther different biological behaviour. Neuroendocrine tumors of gastrointestinal tract originated from neuroendocrine cells scaterred across the gastrointestinal mucosa. As a result these tumors were capable of secreting many different neurotransmiters, which may or may not be biologically active. The incidence of gastrointestinal NETs has been incresing over the last 2 to 3 decades. Patients often presented with vague, nonspecific symptoms which resulted in delayed diagnosis and adequate treatment. In this article, we discuss the nature of gastrointestinal NETs, clinical presentation, treatment options and prognosis.

Gastrointestinal Traumatic Injuries: Gastrointestinal Perforation.

The abdomen is a big place even in a small person. Gastrointestinal trauma can result in injury to the stomach, small bowel, colon, or rectum. Traumatic causes include blunt or penetrating trauma, such as gunshot wounds, stabbings, motor vehicle collisions, and crush injuries. Nontraumatic causes include appendicitis, Crohn disease, cancer, diverticulitis, ulcerative colitis, blockage of the bowel, and chemotherapy. The mechanism of injury will affect both the nature and severity of any resulting injuries. Treatment must address the critical and emergent nature of these injuries as well as issues that affect all trauma situations, which include management of hemodynamic instability.

Disorders of gastrointestinal hypomotility [version 1; referees: 2 approved

Directory of Open Access Journals (Sweden)

Klaus Bielefeldt

2016-08-01

Full Text Available Ingestion and digestion of food as well as expulsion of residual material from our gastrointestinal tract requires normal propulsive, i.e. motor, function. Hypomotility refers to inherited or acquired changes that come with decreased contractile forces or slower transit. It not only often causes symptoms but also may compromise nutritional status or lead to other complications. While severe forms, such as pseudo-obstruction or ileus, may have a tremendous functional impact, the less severe forms of hypomotility may well be more relevant, as they contribute to common disorders, such as functional dyspepsia, gastroparesis, chronic constipation, and irritable bowel syndrome (IBS. Clinical testing can identify changes in contractile activity, defined by lower amplitudes or abnormal patterns, and the related effects on transit. However, such biomarkers show a limited correlation with overall symptom severity as experienced by patients. Similarly, targeting hypomotility with pharmacological interventions often alters gut motor function but does not consistently improve symptoms. Novel diagnostic approaches may change this apparent paradox and enable us to obtain more comprehensive information by integrating data on electrical activity, mechanical forces, patterns, wall stiffness, and motions with information of the flow of luminal contents. New drugs with more selective effects or more specific delivery may improve benefits and limit adverse effects. Lastly, the complex regulation of gastrointestinal motility involves the brain-gut axis as a reciprocal pathway for afferent and efferent signaling. Considering the role of visceral input in emotion and the effects of emotion on visceral activity, understanding and managing hypomotility disorders requires an integrative approach based on the mind-body continuum or biopsychosocial model of diseases.

To discuss the efficiency of RTS (Revised TraumaScore), ISS (Injury Severity Score), and factors that affect mortality and morbidity in gastrointestinal injuries due to blunt trauma.Method and methods: Patients with gastrointestinal injuries due to blunt trauma operated within the last six years have been studied retrospectively in terms of demographics,injury mechanism and localization, additional injuries, RTS and ISS, operative technique, morbidity, mortality and duration of hospitalization. Of the eighteen cases, cause of injury was a traffic accident for 11 (61.1%), fall from height for 5 (27%) and physical attack for 2 (11%). Among the eighteen patients,there were 21 gastrointestinal injuries (11 intestinal, 6 colon,3 duodenum, 1 stomach). 10 (55.6%) had additional intraabdominal injuries while the number for extra-abdominal injuries were 12 (66.7%). Primary suture (10), segmentary resection (9) and pyloric exclusion (2) were the operations performed for the twenty-one gastrointestinal injuries.Although statistically not significant, 13(72.2%) patients with additional injuries compared with 5 (27.8%) patients with isolated gastrointestinal injuries, were found to have lower RTS (7.087/7.841), higher ISS (19.4/12.2), longer duration of hospitalization (11.5/8.4 day) as well as higher morbidity (7/1) and mortality (2/0) rates. Comparing the RTS (7.059/7.490) of patients who have and have not developed morbidity revealed no significant difference.However, ISS (23.9/12.2) was significantly higher in patients who have developed morbidity (p=0.003).

1997-01-01

Purpose: This study aimed to quantify the risk of gastrointestinal cancer following Hodgkin's disease treatment according to age at treatment, type of treatment, and anatomic sites. Methods and Materials: Cases were identified from the records of 2,441 patients treated for Hodgkin's disease between 1961 and 1994. Follow-up averaged 10.9 years, representing 26,590 person-years of observation. Relative risks (RR) for gastrointestinal cancer incidence and mortality were computed by comparison with expected annualized rates for a general population matched for age, sex, and race. Results: Gastrointestinal cancers developed in 25 patients. The incidence RR was 2.5 [95% confidence interval (CI), 1.5-3.5] and mortality RR was 3.8 (CI, 2.4-4.7). Sites associated with significantly increased risks included the stomach [RR 7.3 (CI, 3.4-13.8)], small intestine [RR 11.6 (CI, 1.9-38.3)], and pancreas [RR 3.5 (CI, 1.1-8.5)]. Risk was significantly elevated after combined modality therapy, RR 3.9 (CI, 2.2-5.6). The risk after radiotherapy alone was 2.0 (CI, 1.0-3.4), not a statistically significant elevation. The RR for gastrointestinal cancer was greatest after treatment at young age and decreased with advancing age. It was significantly elevated within 10 years after treatment [RR 2.0 (CI, 1.1-3.5)] and increased further after 20 years [RR 6.1 (CI, 2.5-12.7)]. Risk assessed by attained age paralleled risk according to age at treatment. Fifteen cases of gastrointestinal cancers arose within the irradiation fields. Conclusion: Patients treated for Hodgkin's disease are at modestly increased risk for secondary gastrointestinal cancer, especially after combined modality therapy and treatment at a young age. Risk was highest more than 20 years after treatment, but was significantly elevated within 10 years. Gastrointestinal sites with increased risk included the stomach, pancreas, and small intestine

Purpose. To investigate the sensitivity of mesenteric angiography, technical success of hemostasis, clinical success rate, and complications of transcatheter embolization for the treatment of acute nonvariceal gastrointestinal hemorrhage. Material and Methods. A retrospective review of 200 consecutive patients who underwent mesenteric arteriography for acute nonvariceal gastrointestinal hemorrhage between February 2004 and February 2011 was done. Results. Of 200 angiographic studies, 114 correctly revealed the bleeding site with mesenteric angiography. 47 (41%) patients had upper gastrointestinal hemorrhage and 67 (59%) patients had lower gastrointestinal hemorrhage. Out of these 114, in 112 patients (98%) technical success was achieved with immediate cessation of bleeding. 81 patients could be followed for one month. Clinical success was achieved in 72 out of these 81 patients (89%). Seven patients rebled. 2 patients developed bowel ischemia. Four patients underwent surgery for bowel ischemia or rebleeding. Conclusion. The use of therapeutic transcatheter embolization for treatment of acute gastrointestinal hemorrhage is highly successful and relatively safe with 98% technical success and 2.4% postembolization ischemia in our series. In 89% of cases it was definitive without any further intervention

Full Text Available Upper gastrointestinal neuroendocrine tumors (NETs are rare tumors which are increasingly recognised by practising endoscopists. After confirmation by endoscopic biopsies of these focal lesions, many questions may arise. As NETs are less frequently encountered compared to other malignancies or gastrointestinal pathology, many endoscopists may not fully understand the natural history, diagnosis and management of these tumors. In this review, we aim to update the practising endoscopist on the key clinical features and management of patients with upper gastrointestinal NET.

To investigate the role of sleep quality and psychosocial problems as predictors of functional gastrointestinal disorders (FGIDs) in doctors that work 24 hour-on-call shifts. In this cross-sectional observation study, using the Rome III Questionnaire and Pittsburgh Sleep Quality Index (PSQI), we analyzed 170 doctors with 24 hour-on-call shifts. Among the participants that had experienced a 24 hour-on-call shift within the last 6 mo, 48 (28.2%) had FGIDs. Overall prevalence of irritable bowel syndrome (IBS) and functional dyspepsia (FD) were 16.5% and 17.1%, respectively, with 5.3% exhibiting both. Sleep scores (PSQI) (8.79 ± 2.71 vs 7.30 ± 3.43, P = 0.008), the presence of serious psychosocial alarm (83.3% vs 56.6%, P = 0.004), and the proportion of doctors who experienced over two months of recent on-call work (81.2% vs 68.9%, P = 0.044) were significantly different between individuals with or without FGIDs. Multivariate analysis revealed that presenting serious psychosocial alarm was an independent risk factor for prevalence of FD (OR = 5.47, 95%CI: 1.06-28.15, P = 0.042) and poor sleep quality (PSQI ≥ 6) was a predictor of IBS (OR = 4.17, 95%CI: 1.92-19.02, P = 0.016). Physicians should recognize the role of sleep impairment and psychological stress in the development of FGIDs and a comprehensive approach should be considered to manage patients with FGIDs.

We assess the usefulness of F-18-fluoro-deoxy-glucose (FDG) positron emission tomography (PET) in the evaluation of gastrointestinal metastases. Four cases (five lesions) in which metastases from three lung cancers and one malignant fibrous histiocytoma (MFH) of the femur were found in the gastrointestinal tract were reviewed (men/women 3:1, age 63-78 years, mean 72 years). The five lesions were duodenal, jejunal metastasis, and two stomach metastases from lung carcinoma, and rectal metastasis from MFH of the femur. FDG-PET was unable to detect small masses, but it was able to detect unforeseen lesions such as gastrointestinal metastases because FDG-PET is a whole-body scan in a single-operation examination. FDG-PET imaging provided valuable information for the diagnosis of gastrointestinal metastasis. (author)

We have recognized a unique clinical syndrome in patients with upper gastrointestinal bleeding who are found to have severe esophagitis. We aimed to more clearly describe the clinical entity of upper gastrointestinal bleeding in patients with severe esophagitis. We conducted a retrospective matched case-control study designed to investigate clinical features in patients with carefully defined upper gastrointestinal bleeding and severe esophagitis. Patient data were captured prospectively via a Gastrointestinal Bleeding Healthcare Registry, which collects data on all patients admitted with gastrointestinal bleeding. Patients with endoscopically documented esophagitis (cases) were matched with randomly selected controls that had upper gastrointestinal bleeding caused by other lesions. Epidemiologic features in patients with esophagitis were similar to those with other causes of upper gastrointestinal bleeding. However, hematemesis was more common in patients with esophagitis 86% (102/119) than in controls 55% (196/357) (p bleeding than those without cirrhosis. We have described a unique clinical syndrome in patients with upper gastrointestinal bleeding who have erosive esophagitis. This syndrome is manifest by typical clinical features and is associated with favorable outcomes.

Functional gastrointestinal disorders (FGID) are the most common gastrointestinal disorders. The term "functional" is generally applied to disorders where there are no structural abnormalities. One of the major factors for FGID is abnormal gastrointestinal motility. We have proposed a system for assessing the function of gastric motility using a 3D endoscope. In this previous study, we established a method for estimating characteristics of contraction wave extracted from a 3D shape include contraction wave obtained from stereo endoscope. Because it is difficult to fix the tip position of the endoscope during the examination, estimation of the 3D position between the endoscope and the gastric wall is necessary for the accurate assessment. Then, we have proposed a motion compensation method using 3D scene flow. However, since mucosa has few feature points, it is difficult to obtain 3D scene flow from RGB images. So, we focused on spectral imaging that can enhance visualization of mucosal structure. Spectral image can be obtained without switching optical filters by using technique to estimate spectral reflectance by image processing. In this paper, we propose registration method of measured 3D shape in time series using estimated spectral image. The spectral image is estimated from the RGB image for each frame. 3D scene flow of feature points, that is, enhanced mucosal structure calculated by spectral images in a time series. The position change between the endoscope and gastric wall is estimated by 3D scene flow. We experimented to confirm the validity of the proposed method using papers with a grid of colors close to the background color.

The aim of this study was to determine the effects of soybean meal (SBM) substitution by a mixture of rapeseed meal (RSM), white lupine seeds (WLS) and pea seeds (PS) on productivity, nutrient digestibility, nitrogen retention and gastrointestinal function in Hyplus rabbits. The Control diet (SBM 15 ) contained 15% SBM, whereas Diet SBM 7.5 contained 7.5% SBM, 5% RSM, 4% WLS and 3% PS. In Diet SBM 0, SBM was completely replaced by RSM, WLS and PS (10%, 8% and 6%, respectively). A production trial was performed on 90 Hyplus rabbits aged from 35 to 84 d (45 each sex; 953 ± 4.6 g). A digestion and balance trial was conducted on 30 rabbits. Additionally, several parameters of the gastrointestinal tracts from eight animals from each group were analysed, where special attention was paid to the enzymatic activity of microbiota and the short-chain fatty acids concentration in caecum and colon. The experimental diets did not cause significant differences regarding performance parameters evaluated in vivo and post-mortem, and in the nutrient and energy digestibility or nitrogen retention. The observed changes in the enzymatic activity of large gut microbiota, including the selective increase in secretion of glycoside hydrolases by bacterial cells, seem to be responsible for the unchanged growth performance of rabbits fed diets where SBM was substituted by a mixture of RSM, WLS and PS. The obtained results indicate that in rabbit diets SBM may be, partially or completely, successfully replaced by a feed mixture of RSM, WLS and PS.

Full Text Available Intestinal microbiota play an important role in maintaining normal gastrointestinal (GI function and ensuring that changes in the composition of the intestinal microbiota can promote GI function. The digestive tract is full of bacteria and many of these, including probiotics, are necessary for optimal digestive function. During bacterial gastroenteritis, harmful bacteria invade the digestive tract causing unpleasant symptoms and upsetting the balance between good and bad bacteria. Supplemental probiotics can help restore this balance. Studies have demonstrated that probiotics can often help reduce the severity of symptoms such as diarrhea and may help accelerate recovery. Probiotics are therapeutic preparations of live microorganisms administered in sufficient dosage to be beneficial to health. The therapeutic effects of these microorganisms appear to be strain specific. Primal Defense®, a unique, probiotic, bacterial compound, contains probiotics that support gut flora balance, promote consistent bowel function, control stomach acid levels to quickly eliminate burning sensation in the stomach and maintain immune system response. The probiotics in Primal Defense® maximize the benefits of a healthy diet by supporting normal absorption and assimilation of nutrients in the gut. Nearly 75% of our immune defenses are located in the digestive tract, so maintaining a favorable bacterial balance in the intestines (ideally 80% good or neutral bacteria to 20% bad or harmful bacteria is crucial to achieving and maintaining optimum health.

This study aimed to determine whether functional gastrointestinal disorders are more common among adolescents with self-reported poor sleep. Junior middle school and senior high school students (n = 1,362) were recruited from schools in Shanghai. Students completed two questionnaires: the questionnaire for irritable bowel syndrome (IBS) in adolescents and the Pittsburgh Sleep Quality Index. The prevalence of poor sleep was 34.29% [95% confidence interval (CI) = 31.77-36.81] and there was no significant difference between genders (P = 0.991). The tendency towards poor sleep increased with age, with age group yielding a significant effect (P = 0.001). In junior middle school and senior high school students, the propensity towards poor sleep was 30.10% (95% CI = 27.08-33.12%) and 42.11% (95% CI = 37.67-46.55%), respectively. Among students with poor sleep, the prevalence of IBS was 19.70% (95% CI = 16.09-23.31). After adjusting for age, sex, night pain, and psychological factors, IBS was significantly more common in students with poor sleep (odds ratio = 1.92; 95% CI = 1.07-2.58). We conclude that IBS is prevalent in students with poor sleep. Poor sleep was independently associated with IBS among adolescents in Shanghai China.

Since the first descriptions made by Golden and Stout, this group of mesenchymal lesions is considered of muscular origin and they were named as leiomyoma, cellular leiomyoma, epithelioid leiomyoma, leiomyoblastoma, bizarre leiomyoma and leiomyosarcoma. But Mazur and Clark created the term estromal tumor only after they began to use the inmunohistochemistry and subsequently showed the absence of muscular markers, and the occasional presence of neural markers. Nowadays, gastrointestinal estromal tumors are called the primary mesenchymal CD117 positive, fusiform or epithelioid tumors of the gastrointestinal tract, epiplon, mesenterio, and retroperitoneum. The gastrointestinal estromal tumors appear at the wall of the digestive tube: stomach (50-60 %), small intestine (20-30 %), large intestine (10 %) and esophagus (5 %), and occasionally in epiplon, mesenterio, and retroperineum (5 %). In our work we present a 67 year-old patient, entered in our hospital for presenting high digestive bleeding. We studied the case, and found a 6 cm tumor of the gastric fundus. The tumor was operated and the definitive results of the pathologic anatomy showed a gastrointestinal estromal tumor

Minimally invasive techniques have revolutionized operative surgery. Computer aided surgery and robotic surgical systems strive to improve further on currently available minimally invasive surgery and open new horizons. Only several centers are currently using surgical robots and publishing data. In gastrointestinal surgery, robotic surgery is applied to a wide range of procedures, but is still in its infancy. Cholecystectomy, Nissen fundoplication and Heller myotomy are among the most frequently performed operations. The ZEUS (Computer Motion, Goleta, CA) and the da Vinci (Intuitive Surgical, Mountain View, CA) surgical systems are today the most advanced robotic systems used in gastrointestinal surgery. Most studies reported that robotic gastrointestinal surgery is feasible and safe, provides improved dexterity, better visualization, reduced fatigue and high levels of precision when compared to conventional laparoscopic surgery. Its main drawbacks are the absence of force feedback and extremely high costs. At this moment there are no reports to clearly demonstrate the superiority of robotics over conventional laparoscopic surgery. Further research and more prospective randomized trials are needed to better define the optimal application of this new technology in gastrointestinal surgery.

Sonography of the gastrointestinal tract in fetuses, neonates and children entails no known biological risk, permits serial scanning and can provide information unobtainable with any other imaging modality. In experienced hands it can be used as the initial imaging technique in a number of gastrointestinal diseases and conditions. This book provides a comprehensive account of the current state of the art regarding sonography in this context. An introductory chapter compares the merits of sonography and magnetic resonance imaging of the fetal gastrointestinal tract. Subsequent chapters focus on the technique, pitfalls and findings in a wide variety of applications, including antropyloric diseases, bowel obstruction, bowel wall thickening, colitis, appendicitis, some types of intussusception, abdominal wall and umbilical abnormalities, intraperitoneal tumors, and trauma. In each case the sonographic morphology is considered in depth with the aid of high-quality illustrations. A concluding chapter comprises a quiz based on 15 case reports. Gastrointestinal Tract Sonography in Fetuses and Children will be of value to all with an interest in this field. (orig.)

Effectiveness of Lactobacillus reuteri for prevention and treatment of functional gastrointestinal disorders in infants, children and adolescents (Review

2013-10-01

Full Text Available Functional gastrointestinal disorders (FGIDs with their extremely high prevalence and important influence on patients’ quality of life and health costs represent a major problem. Their etiopathogenesis is multifactorial and disturbances in a composition of intestinal microbiota as well as specific potentially pathogenic microorganisms seem to have crucial role in it. Probiotics with their broad spectrum of actions, including strengthening of colonisatiton resistance against pathogens, enhancement of barrier function, regulation of intestinal immune response, alleviation of inflammation, and both direct and indirect influence on gut motility or sensitivity, represent one of the most promising therapeutic strategies for these disorders. Numerous clinical studies revealed their efficacy in different FGIDs. However, the pathogenesis of different types of disorders is not similar, and neither are mechanisms of action of different probiotic strains. Several Lactobacillus reuteri strains exhibit various characteristics such as secretion of antimicrobial reuterin, production of short-chain fatty acids, down-regulation of inflammatory immune response, and direct influence on enteric nervous system among the others, which render them good candidates for prevention and treatment of various FGIDs. This paper reviews clinical studies on the effectiveness of Lactobacillus reuteri in the therapy of FGIDs in infants, children and adolescents. Results of multiple studies support its use for prevention and treatment of infant colic and improvement of delayed gastric emptying and regurgitation. In addition, individual studies suggest potential usefulness of specific Lactobacillus reuteri strains for the alleviation of constipation and functional abdominal pain.

To date, there are no large studies on videocapsule endoscopy in systemic sclerosis (SSc). Consequently, the prevalence and features of gastrointestinal mucosal abnormalities in SSc have not been determined. To determine both prevalence and characteristics of gastrointestinal mucosal abnormalities in unselected patients with SSc, using videocapsule endoscopy. To predict which SSc patients are at risk of developing potentially bleeding gastrointestinal vascular mucosal abnormalities. Videocapsule endoscopy was performed on 50 patients with SSc. Prevalence of gastrointestinal mucosal abnormalities was 52%. Potentially bleeding vascular mucosal lesions were predominant, including: watermelon stomach (34.6%), gastric and/or small intestinal telangiectasia (26.9%) and gastric and/or small intestinal angiodysplasia (38.5%). SSc patients with gastrointestinal vascular mucosal lesions more often exhibited: limited cutaneous SSc (P = 0.06), digital ulcers (P = 0.05), higher score of nailfold videocapillaroscopy (P = 0.0009), anaemia (P = 0.02), lower levels of ferritin (P correlation between gastrointestinal vascular mucosal lesions and presence of severe extra-digestive vasculopathy (digital ulcers and higher nailfold videocapillaroscopy scores). This latter supports the theory that SSc-related diffuse vasculopathy is responsible for both cutaneous and digestive vascular lesions. Therefore, we suggest that nailfold videocapillaroscopy may be a helpful test for managing SSc patients. In fact, nailfold videocapillaroscopy score should be calculated routinely, as it may result in identification of SSc patients at higher risk of developing potentially bleeding gastrointestinal vascular mucosal lesions. © 2014 John Wiley & Sons Ltd.

The objective of this review is to revise the literature and summarize the main chronic gastrointestinal manifestations of Chagas disease. The chronic gastrointestinal manifestations of Chagas disease are mainly a result of enteric nervous system impairment caused by T. cruzi infection. The anatomical locations most commonly described to be affected by Chagas disease are salivary glands, esophagus, lower esophageal sphincter, stomach, small intestine, colon, gallbladder and biliary tree. Chagas disease has also been studied in association with Helicobacter pylori infection, interstitial cells of Cajal and the incidence of gastrointestinal cancer.

Full Text Available Background. In cases of severe forms of infectious di­seases, in addition to local inflammation, secondary lesions of the gastrointestinal organs may occur. We aimed to study the semiotics and epidemiology of gastrointestinal symptoms in children with acute neuroinfection. Materials and methods. This observational, retrospective, case-control study. We analyzed cases of in-patient treatment of children aged 1 month to 18 years with acute neuroinfections (meningitis, encephalitis and encephalomyelopolyneuropathy. Results. The study included 117 patients with acute central nervous system infections. Clinical symptoms of gastrointestinal infection were observed in 83 (70.9 % children. Among revealed symptoms, disorders of intestinal moti­lity, such as constipation and diarrhea, were prevalent. Manifestations of hepatobiliary system dysfunction included increased transaminase level (alanine aminotransferase (ALT, alkaline phosphatase, gamma-glutamyltransferase (GGTF and/or ultrasound changes (enlargement, diffuse structural changes and were observed in 39.1 % of patients. Among the laboratory parameters, elevated ALT level was observed in 8.3 % of patients, bilirubin was elevated in only one child, alkaline phosphatase was above the age norm in 11.8 %, an increased GGTF above the age norm was observed in 31.3 % of patients. The level of intestinal fatty acid binding protein (I-FABP was elevated in 86.4 %, and L-type fatty acid binding protein (L-FABP — in all (100 % children. Clinical manifestations of gastrointestinal dysfunction (the presence of at least one of the gastrointestinal symptoms had an inverse relationship with the child’s age (rpb = –0.19, p = 0.033, correlated with staying in intensive care unit (odds ratio (OR = +5.25; 95% confidence interval (CI 1.62–16.97, artificial ventilation (OR = +4.5; 95% CI 1.00–21.69 and level of I-FABP (rpb = 0.34, p = 0.019.

OBJECTIVE To evaluate the usefulness of noncontrast abdominal CT and abdominal ultrasonography for the detection of mechanical gastrointestinal obstruction in dogs and compare intestinal diameter ratios between dogs with and without obstruction. DESIGN Controlled trial. ANIMALS 16 client-owned dogs with physical and radiographic findings consistent with mechanical gastrointestinal obstruction. PROCEDURES Abdominal ultrasonography and CT were performed for all dogs, followed by laparoscopy and exploratory laparotomy. Time required for image acquisition and presence and location of gastrointestinal obstruction were assessed with both imaging modalities. Findings were compared with those of exploratory surgery. Maximum and minimum intestinal diameters were recorded on CT scans; values were converted to a ratio and compared between dogs with and without obstruction. RESULTS Results of abdominal CT and exploratory surgery for the diagnosis of mechanical obstruction agreed for all 16 dogs; 10 dogs had complete obstruction, 3 had partial obstruction, and 3 had no obstruction. In 1 dog with functional ileus, abdominal ultrasonography resulted in an incorrect diagnosis of mechanical obstruction. Median (interquartile range) image acquisition time for abdominal CT (2.5 minutes [2.0 to 3.8 minutes]) was markedly and significantly shorter than that for ultrasonography (26.0 minutes [22.0 to 35.8 minutes]). In both dorsal and transverse CT planes, dogs with gastrointestinal obstruction (partial or complete) had significantly larger intestinal diameter ratios than dogs without obstruction. CONCLUSIONS AND CLINICAL RELEVANCE Abdominal CT was feasible, rapid, and accurate for the diagnosis of mechanical obstruction in dogs with clinical signs and physical examination findings consistent with partial or complete gastrointestinal obstruction.

The aim of this study was to define the imaging characteristics of primary and recurrent gastrointestinal stromal tumors (GIST) in computed tomography with respect to the tumor size. Computed tomography was performed in 35 patients with histologically confirmed gastrointestinal stromal tumors and analyzed retrospectively by two experienced and independent radiologist. The following morphologic tumor characteristics of primary (n=20) and (n=16) recurrent tumors were evaluated according to tumor size, shape, homogeneity, density compared with liver, contrast enhancement, presence of calcifications, ulcerations, fistula or distant metastases and the anatomical relationship to the intestinal wall, and the infiltration of adjacent visceral organs. Small GIST ( 5-10 cm) demonstrated an irregular shape, inhomogeneous density on unenhanced and contrast-enhanced images, a combined intra- and extraluminal tumor growth with aggressive findings, and infiltration of adjacent organs in 9 primary diagnosed and 2 recurrent tumors. Large GIST (>10 cm), which were observed in 8 primary tumors and 11 recurrent tumors, showed an irregular margin with inhomogeneous density and aggressive findings, and were characterized by signs of malignancy such as distant and peritoneal metastases. Small recurrent tumors had a similar appearance as compared with large primary tumors. Computed tomography gives additional information with respect to the relationship of gastrointestinal stromal tumor to the gastrointestinal wall and surrounding organs, and it detects distant metastasis. Primary and recurrent GIST demonstrate characteristic CT imaging features which are related to tumor size. Aggressive findings and signs of malignancy are found in larger tumors and in recurrent disease. Computed tomography is useful in detection and characterization of primary and recurrent tumors with regard to tumor growth pattern, tumor size, and varied appearances of gastrointestinal stromal tumors, and indirectly

1986-01-01

Gastrointestinal radiation syndrome occurred in 27 mongrel dogs irradiated with 9-12 Gy of 60 Co γ-rays. Six of them received autologous bone marrow transplantation (auto-BMT), 10 animals were treated with symptomatic and supportive measures only, and the remaining 11 dogs served as controls without any treatment. All animals of the latter two groups died between 3 and 11 days after irradiation without any evidence of hematopoietic recovery. Recovery of gastrointestinal injury was found in 7 dogs treated with symptomatic and supportive measures only. Of 6 dogs having received auto-BMT 2 died 15 days after irradiation, 3 survived over 30 days with recovery of gastrointestinal and hematopoietic injury but died of distemper later, and the other one, still alive, has survived for more than 4 years. The results show that the effective measures for gastrointestinal radiatin syndrome are BMT and symptomatic therapy

The authors report a case of 6-week-old baby boy with congenital diaphragmatic hernia(CDH). He presented with nonspecific gastrointestinal symptoms. CDH is commonly manifested by nonspecific respiratory problems. The symptoms of CDH in older infants are atypical and misleading. Children may have only gastrointestinal problems even the acute abdomen. In our case, the ultrasound examination of abdomen did not detect the exact cause of vomiting and intolerance of oral intake, but the explanation has brought classic chest X-ray. (author)

We report on a patient who developed massive gastrointestinal hemorrhage related to the use of fluoxetine in combination with aspirin and clopidogrel. A 58-year-old man was admitted with a posterior circulation infarct with significant weakness in all four limbs and dysarthria. Aspirin and clopidogrel were started. Fluoxetine was started for pharmacological neurostimulation to promote motor recovery and for low mood. He developed gastrointestinal hemorrhage a week after fluoxetine was started. Fluoxetine was suspended and investigations failed to reveal the source of the bleeding. He was then restarted on fluoxetine along with dual antiplatelets, and gastrointestinal hemorrhage recurred after 1 week. He was extensively investigated for a source of gastrointestinal hemorrhage, and again no source could be identified. Eventually, fluoxetine was switched to mirtazapine with no further gastrointestinal hemorrhage. He remained on dual antiplatelets. A number of case-control and cohort studies had identified the association of gastrointestinal hemorrhage with the use of selective serotonin reuptake inhibitor (SSRI). We hope to raise awareness of this association in physical medicine and rehabilitation physicians as the use of SSRI is expected to rise.

-Precision medicine is the promise of individualized therapy and management of patients based on their personal biology. There are now multiple global initiatives to perform whole-genome sequencing on millions of individuals. In the United States, an early program was the Million Veteran Program, and a more recent proposal in 2015 by the president of the United States is the Precision Medicine Initiative. To implement precision medicine in routine oncology care, genetic variants present in tumors need to be matched with effective clinical therapeutics. When we focus on the current state of precision medicine for gastrointestinal malignancies, it becomes apparent that there is a mixed history of success and failure. -To present the current state of precision medicine using gastrointestinal oncology as a model. We will present currently available targeted therapeutics, promising new findings in clinical genomic oncology, remaining quality issues in genomic testing, and emerging oncology clinical trial designs. -Review of the literature including clinical genomic studies on gastrointestinal malignancies, clinical oncology trials on therapeutics targeted to molecular alterations, and emerging clinical oncology study designs. -Translating our ability to sequence thousands of genes into meaningful improvements in patient survival will be the challenge for the next decade.

The purpose of our study is to investigate the delay in diagnosis of patients with biopsy-proven celiac disease in those who present with gastrointestinal complaints vs nongastrointestinal complaints at our tertiary care center. Celiac disease is an autoimmune disorder that affects approximately 1% of the population worldwide. Celiac disease can have variable clinical presentations; it can be characterized by predominately gastrointestinal symptoms, or it may present without any gastrointestinal symptoms. We retrospectively reviewed the charts of 687 adult patients who carried the diagnosis of celiac disease. Patients included had biopsy-proven celiac disease and were categorized based on presence or absence of gastrointestinal symptoms prior to their diagnosis. There were 101 patients with biopsy-proven celiac disease that met inclusion criteria. Fifty-two patients presented with gastrointestinal symptoms and 49 had nongastrointestinal complaints. Results from Mann-Whitney statistical analysis showed a median delay in diagnosis of 2.3 months for the gastrointestinal symptoms group and 42 months for the nongastrointestinal group (P symptoms had abnormal thyroid-stimulating hormone, as opposed to 15.5% in the gastrointestinal symptom group (P = .004). Of patients with nongastrointestinal symptoms, 69.4% had anemia, compared with 11.5% of the gastrointestinal symptom group (P symptom group, 68%, were noted to have abnormal bone density scans, compared with 41% in the gastrointestinal symptom group. No sex differences were noted on chi-squared analysis between the 2 groups (P = .997). Although there is growing awareness of celiac disease, the delay in diagnosis for patients without gastrointestinal symptoms remains prolonged, with an average delay of 3.5 years.

In order to determine the effectiveness of a Gastrointestinal Severity Index to screen for gastrointestinal disorders, the Gastrointestinal Severity Index was administered to 135 children with autism spectrum disorders and 146 comparisons with and without gastrointestinal disorders. The mean Gastrointestinal Severity Index scores of the groups were 3.53 ± 1.78, 3.15 ± 1.99, 0.81 ± 1.25, and 0.29 ± 0.76 (comparative pediatric patients with gastrointestinal disorder = autism spectrum disorder + gastrointestinal disorder > autism spectrum disorder-gastrointestinal disorder > comparative pediatric patients without gastrointestinal disorder, respectively), Ps disorders. The area under the receiver operating characteristic curve (0.97) for the comparison group was higher (P autism spectrum disorder children indicating that the Gastrointestinal Severity Index was more effective in screening for gastrointestinal disorders in comparisons. However, the same Gastrointestinal Severity Index cutoff score of 2 and above yielded, respectively, sensitivity and specificity rates of 92% and 93% for comparisons and 80% and 79% for autism spectrum disorder children. The negative and positive predictive values based on these sensitivity and specificity rates were calculated for a range of prevalences of gastrointestinal disorders and indicated that the Gastrointestinal Severity Index may be useful for screening children with and without autism spectrum disorder for gastrointestinal symptoms.

Objective: To investigate the value of percutaneous transsplenic varices embolization (PTSVE) for treatment of upper gastrointestinal bleeding. Methods: Twenty cases with liver cirrhosis and portal hypertension suffered upper gastrointestinal bleeding. PTSVE was administered to them with hardener and coils. Among them, 8 cases had massive hepatocellular carcinoma (HCC) in right lobe; 10 cases with hepatocellular carcinoma had portal vein tumor thrombus and occlusion; the other two cases with liver cirrhosis had portal vein thrombosis. All of these cases were not suitable for percutaneous transhepatic varices embolization (PTHVE). PTSVE was performed under the guidance of fluoroscopy. Results: Technical success was achieved in 18 patients. A total of 35 gastric coronary veins were embolized. In all these cases, upper gastrointestinal bleeding stopped after PTSVE. There was no recurrence within 1 month follow-up. No serious complication occurred. Conclusion: PTSVE is a safe and efficient alternative treatment for upper gastrointestinal bleeding, especially for cases with portal vein occlusion or with massive HCC in right lobe of liver.

To investigate the sensitivity of mesenteric angiography, technical success of hemostasis, clinical success rate, and complications of transcatheter embolization for the treatment of acute non variceal gastrointestinal hemorrhage. Material and Methods. A retrospective review of 200 consecutive patients who underwent mesenteric arteriography for acute non variceal gastrointestinal hemorrhage between February 2004 and February 2011 was done. Results. Of 200 angiographic studies, 114 correctly revealed the bleeding site with mesenteric angiography. 47 (41%) patients had upper gastrointestinal hemorrhage and 67 (59%) patients had lower gastrointestinal hemorrhage. Out of these 114, in 112 patients (98%) technical success was achieved with immediate cessation of bleeding. 81 patients could be followed for one month. Clinical success was achieved in 72 out of these 81 patients (89%). Seven patients rebled. 2 patients developed bowel ischemia. Four patients underwent surgery for bowel ischemia or rebleeding. Conclusion. The use of therapeutic transcatheter embolization for treatment of acute gastrointestinal hemorrhage is highly successful and relatively safe with 98% technical success and 2.4% post embolization ischemia in our series. In 89% of cases it was definitive without any further intervention.

Although the prevalence of malnutrition in the old age is increasing worldwide a synthetic understanding of the impact of aging on the intake, digestion, and absorption of nutrients is still lacking. This review article aims at filling the gap in knowledge between the functional decline of the aging gastrointestinal tract (GIT) and the consequences of malnutrition on the health status of elderly. Changes in the aging GIT include the mechanical disintegration of food, gastrointestinal motor function, food transit, chemical food digestion, and functionality of the intestinal wall. These alterations progressively decrease the ability of the GIT to provide the aging organism with adequate levels of nutrients, what contributes to the development of malnutrition. Malnutrition, in turn, increases the risks for the development of a range of pathologies associated with most organ systems, in particular the nervous-, muscoskeletal-, cardiovascular-, immune-, and skin systems. In addition to psychological, economics, and societal factors, dietary solutions preventing malnutrition should thus propose dietary guidelines and food products that integrate knowledge on the functionality of the aging GIT and the nutritional status of the elderly. Achieving this goal will request the identification, validation, and correlative analysis of biomarkers of food intake, nutrient bioavailability, and malnutrition. PMID:26091351

Gastrointestinal stromal tumors (GISTs) include 80% of gastrointestinal mesenchymal tumors that originate from interstitial Cajal cells and include 0.1-3% of GI malignancies, and the stomach is the most commonly involved organ. The only potentially curative treatment is surgical resection with clear margins. Although laparoscopic resection of small GISTs is a standard treatment, there is controversy about laparoscopic surgical resection for large and giant GISTs. A 52-year-old woman, a known case of large GIST of the stomach that was under neoadjuvant imatinib therapy, was admitted to the emergency department due to acute massive gastrointestinal bleeding (GIB). The patient underwent laparoscopic total gastrectomy and received adjuvant imatinib after surgery. Laparoscopic resection is a safe and feasible method in large and giant GISTs with oncologic and long-term outcomes comparable to open surgery, and with better short-term outcomes.

Acute gastrointestinal bleeding may be localized using noninvasive radionuclide methods. We have favored the use of technetium-99m sulfur colloid with sequential imaging because of the rapid clearance of background activity. Definition of the site of upper gastrointestinal bleeding, however, may be obscured by intense uptake of radioactivity by liver and spleen. The sensitivity of the method is such that the bleeding rates of 0.05-0.1 ml/min can be detected compared to a sensitivity of 0.5 ml/min for angiography.

The gastrointestinal eosinofilic disorders are little frequent diseases, of etiopatogenia little clear, that are characterized by the presence of an infiltrated eosinofilo that can affect the different layers of the wall of the alimentary canal in absence of known causes of eosinofilia. The clinical manifestations are variable and the symptoms are conditioned by the degree of eosinofilia of the wall, the number of layers affected and the segment of the gastrointestinal tract implied. The presentations symptoms vary from diarrhea, vomits, abdominal pain and loss of weigh until the acute intestinal obstruction. They are characterized to present peripherical eosinofilia, although it is not a forced criterion. Its definite diagnosis is anatomopatologic. The steroid use is considered as the angular stone of the treatment. We present two cases, with different clinical presentation forms, with initial answer to steroids and later relapse after the suspension of these, remaining without symptoms actually with dependency of low doses of steroids. Next we will do the revision of the available literature emphasizing the pathophysiologic data, the clinical evaluation and the therapeutic aspects

The clinical presentation of congenital portosystemic shunt is variable and gastrointestinal bleeding is an uncommon presentation. To describe the imaging features of congenital portosystemic shunt as it presented in 11 children with (n = 6) and without gastrointestinal bleeding (n = 5). We performed a retrospective study on a clinical and imaging dataset of 11 children diagnosed with congenital portosystemic shunt. A total of 11 children with congenital portosystemic shunt were included in this study, 7 with extrahepatic portosystemic shunts and 4 with intrahepatic portosystemic shunts. Six patients with gastrointestinal bleeding had an extrahepatic portosystemic shunt, and the imaging results showed that the shunts originated from the splenomesenteric junction (n = 5) or splenic vein (n = 1) and connected to the internal iliac vein. Among the five cases of congenital portosystemic shunt without gastrointestinal bleeding, one case was an extrahepatic portosystemic shunt and the other four were intrahepatic portosystemic shunts. Most congenital portosystemic shunt patients with gastrointestinal bleeding had a shunt that drained portal blood into the iliac vein via an inferior mesenteric vein. This type of shunt was uncommon, but the concomitant rate of gastrointestinal bleeding with this type of shunt was high. (orig.)

Increased gastrointestinal blood flow is essential for euryhaline fishes to maintain osmotic homeostasis during the initial phase of a transition from freshwater to seawater. However, the cardiorespiratory responses and hemodynamic changes required for a successful long-term transition to seawater remain largely unknown. In the present study, we simultaneously measured oxygen consumption rate (ṀO2), cardiac output (CO), heart rate (HR), and gastrointestinal blood flow (GBF) in rainbow trout (Oncorhynchus mykiss) acclimated to either freshwater or seawater for at least 6 wk. Seawater-acclimated trout displayed significantly elevated ṀO2 (day: 18%, night: 19%), CO (day: 22%, night: 48%), and GBF (day: 96%, night: 147%), demonstrating that an overall cardiorespiratory upregulation occurs during seawater acclimation. The elevated GBF was achieved via a combination of increased CO, mediated through elevated stroke volume (SV), and a redistribution of blood flow to the gastrointestinal tract. Interestingly, virtually all of the increase in CO of seawater-acclimated trout was directed to the gastrointestinal tract. Although unfed seawater-acclimated trout displayed substantially elevated cardiorespiratory activity, the ingestion of a meal resulted in a similar specific dynamic action (SDA) and postprandial GBF response as in freshwater-acclimated fish. This indicates that the capacity for the transportation of absorbed nutrients, gastrointestinal tissue oxygen delivery, and acid-base regulation is maintained during digestion in seawater. The novel findings presented in this study clearly demonstrate that euryhaline fish upregulate cardiovascular function when in seawater, while retaining sufficient capacity for the metabolic and cardiovascular changes associated with the postprandial response.

Lactase is an enzyme involved in the hydrolysis of lactose. Deficiency of the enzyme (hypolactasia) may be determined genetically or arise secondarily to disease of small intestine. Under this condition, lactose enters the colon where it is fermented by intestinal microflora and turns to gases and short-chain fatty acids, causing gastrointestinal symptoms known as lactose intolerance (LI). To investigate the incidence of lactose malabsorption (LM), LI and the coexistence of these two conditions in children with upper gastrointestinal tract diseases (UGTD), malabsorption syndrome, inflammatory bowel disease (IBD) and functional gastrointestinal disorders (FGID). Hydrogen breath test (HBT) was conducted in 387 pediatric patients in years 2010-2013. Two hundred thirty two children with gastrointestinal tract diseases were selected and assigned to groups - UGTD, malabsorption syndrome, IBD or FGID. For each group the frequency of LM, frequency and severity of LI and the frequency of their co-occurrence were calculated. Lactose malabsorption was observed in 37.08% of patients with gastrointestinal diseases. Positive HBT result was the most common in children with malabsorption syndrome (52.50%) and less common in UGTD (30.85%), especially in ulcer disease (23.53%). Symptoms after lactose ingestion affected 36.64% of the subjects, and were more specific to lactose malabsorbers than to lactose absorbers (72.10% vs. 15.75%). The higher frequency of LI was noted in children with FGID, especially in irritable bowel syndrome (IBS) (65.22%). The lowest incidence of symptoms was obtained in children with UGTD, especially in those with ulcer disease (27.44%). The incidence of LM with LI was noted in 27.16% of all patients and was the highest in IBS (47.83%) and the lowest in ulcer disease (15.78%). Lactose malabsorption is a common problem in children with gastrointestinal diseases, especially in children with bowel diseases. Lactose intolerance is related to LM, but does not

Gastrointestinal stromal tumors are the most frequent non-epithelial digestive tumors, being classified in the group of primitive mesenchymal tumors of the digestive tract. These tumors have a non predictable evolution and where stratified regarding the risk for malignant behavior in 4 categories: very low risk, low risk, intermediate risk and high risk. We performed a retrospective non randomised study including the patients with gastrointestinal stromal tumors treated in the Department of General Surgery and Liver Transplantation of Fundeni Clinical Institute in the period January 2002 - June 2007, to define the epidemiological, clinico-paraclinical, histological and especially evolutive features of the gastrointestinal stromal tumors from this group, with a special regard to the risk factors for their malignant behavior. The most important risk factors in gastrointestinal stromal tumors are the tumor size and the mitotic index, based on them being realised the classification of Fletcher in the 4 risk categories mentioned above. In our group all the local advanced or metastatic gastrointestinal stromal tumors, regardless of their location, were classified in the group of high risk for the malignant behavior. The gastric location and the epithelioid type were positive prognostic factors, and the complete resection of the tumor, an other important positive prognostic feature, was possible in about 80% of the cases, probably because the gastrointestinal stromal tumors in our study were diagnosed in less advanced evolutive situations, only about one third being metastatic and about 14% being locally advanced at the time of diagnose. The association with other neoplasias was in our cases insignificant, only 5% of the patients presenting concomitant malignant digestive tumors and 7.6% intraabdominal benign tumors. Gastrointestinal stromal tumors remain a challenge for the medical staff, regarding their diagnose and therapeutical management, the stratification of the

Bayesian networks are graphical probabilistic models that represent causal and other relationships between domain variables. In the context of medical decision making, these models have been explored to help in medical diagnosis and prognosis. In this paper, we discuss the Bayesian network formalism in building medical support systems and we learn a tree augmented naive Bayes Network (TAN) from gastrointestinal bleeding data. The accuracy of the TAN in classifying the source of gastrointestinal bleeding into upper or lower source is obtained. The TAN achieves a high classification accuracy of 86% and an area under curve of 92%. A sensitivity analysis of the model shows relatively high levels of entropy reduction for color of the stool, history of gastrointestinal bleeding, consistency and the ratio of blood urea nitrogen to creatinine. The TAN facilitates the identification of the source of GIB and requires further validation.

To determine the pattern, presentation and outcome of gastrointestinal injuries from blunt abdominal trauma in children. A retrospective study. Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. Twenty one children managed for gastrointestinal injuries from blunt trauma from 1984-2002. The pattern, presentation, management and outcome of gastrointestinal injuries from blunt trauma. In the 19 year period, 1984-2002, 92 children were treated for blunt abdominal trauma, 21(23%) of who had injuries to the gastrointestinal tract. Three presenting after 24 hours had evidence of peritonitis. In six children with isolated gastrointestinal tract (GIT) injury who presented within two hours, abdominal signs were vague at initial evaluation but became marked over a few hours at repeated examination. In eight with associated intraabdominal injuries, abdominal signs were marked at initial examination and five presented with shock. Free peritoneal air was present on plain abdominal and chest radiograph in three of ten patients, dilated bowel loops in six and fluid levels in one. Diagnostic peritoneal lavage or paracentesis was positive in four patients with isolated GIT injuries and eight with associated intraabdominal injuries. There were 24 injuries in the 21 patients consisting of 15 perforations, five contusions, two seromuscular tears, and two gangrene from mesenteric injury. The small intestine was involved in 11 patients, colon six, stomach five, duodenum one and rectum one. Seven (35%) patients had associated extraabdominal injuries. Treatment consisted of simple closure of perforations, over sewing of contusions, resection and anastomosis for gangrene and repair with protective stoma for the rectal injury. One patient each developed prolonged ileus, urinary tract infection and chest infection, respectively postoperatively. Mortality was 28%, all of who had associated intraabdominal or extraabdominal injuries. Gastrointestinal injury from blunt abdominal trauma in

Assessment of quantitative and qualitative characteristics of gastrointestinal microflora in patients with chronic cholecystitis. Bacteriological analysis of biopsy samples of esophageal and gastric mucosae as well as stool samples was performed in 10 healthy volunteers and 28 patients with chronic cholecystitis. Opportunistic microorganisms are acquiring greater significance in formation of gastrointestinal microbiocenosis. Significant increase of both isolation rate and density of gastrointestinal tract colonization by staphylococci, enterobacteriae and anaerobic microorganisms was revealed. Obtained results showed abnormalities of microbiocenosis of esophageal and gastric mucosae and presence of intestinal disbacteriosis of different degrees of intensity.

Gastrointestinal (GI) sensory-motor abnormalities are common in patients with diabetes mellitus and may involve any part of the GI tract. Abnormalities are frequently sub-clinical, and fortunately only rarely do severe and life-threatening problems occur. The pathogenesis of abnormal upper GI sensory-motor function in diabetes is incompletely understood and is most likely multi-factorial of origin. Diabetic autonomic neuropathy as well as acute suboptimal control of diabetes has been shown to impair GI motor and sensory function. Morphological and biomechanical remodeling of the GI wall develops during the duration of diabetes, and may contribute to motor and sensory dysfunction. In this review sensory and motility disorders of the upper GI tract in diabetes is discussed; and the morphological changes and biomechanical remodeling related to the sensory-motor dysfunction is also addressed.

Objective: To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage. Methods: Twenty patients with gastrointestinal hemorrhage received celiac arteries, superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy. Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superselective catheterization with gelfoam particles, gelfoam particles and coils, polyvinyl alcohol particles. Results: The positive signs were observed in 13 cases. The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular, aneurysm, tumorous vascularization and staining, artery affect and local vasospasm. The bleedings were stopped immediately in 8 patients. No rebleeding and intestinal ischaemia or necrosis were observed in 30 days. One patient died in the second day after embolization from multiple organ failure. Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation. Conclusion: DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding. Transcatheter embolization is effective and safe to control the hemorrhage. (authors)

Neonatal gastrointestinal involvement and congenital cytomegalovirus

2016-11-01

Full Text Available Cytomegalovirus (CMV is the most common cause of congenital viral infection, affecting 0.2 to 2.3% of all live births in developed countries. Very low birth weight and extremely low birth weight newborns are at higher risk of symptomatic CMV infection, most commonly secondary and acquired through breast milk. Gastrointestinal involvement is rare in acquired CMV infections, but it could be an important manifestation of postnatal infection in preterm infants admitted to neonatal intensive care units. Early onset of CMV gastrointestinal signs/symptoms is very rare. In a review of the literature it is described in 5 newborns in the first 24 hours of life, and 6 considering the onset in the first week of life. This review describes also a case report of congenital CMV in an immunocompetent newborn with onset of gastrointestinal signs immediately after birth: a possible association between viral infection and enteric manifestations was considered in the differential diagnosis. A review of the literature of the different case reports found has done, with description and comparison of the different patients and clinical presentations.

Gastrointestinal Complications of Obesity

Camilleri, Michael; Malhi, Harmeet; Acosta, Andres

2017-01-01

Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

Radiation burden estimates for upper gastrointestinal function studies employing the following orally administered radiopharmaceuticals are reported. Technetium 99m sulfur colloid (Tc-99m-SC) in water, Indium-111-DTPA in water, Tc-99m-DTPA in water, Indium-113m DTPA in water, Tc-99m Ovalbumin, Tc-99m sulfur colloid in a cooked egg, Tc-99m sulfur colloid in vivo labeled chicken liver, and Indium-111 colloid in vivo labeled chicken liver. Orally administered radiopharmaceuticals for upper gastrointestinal studies afford clinician and investigator valuable clinical and physiologic information not previously obtainable using other techniques. The radiation burden to the patient from single or sequential studies is acceptable in comparison to fluoroscopy which results in approximately 5000 millirem per minute of exposure. The variety of preparations listed above should make these types of studies available in any routinely equipped nuclear medicine radiopharmacy laboratory

Full Text Available Introduction : There is increasing interest in sedation for upper gastrointestinal endoscopy (UGE. Prospective randomized studies comparing sedation properties and complications of propofol and midazolam/meperidine in upper gastrointestinal endoscopy (UGE are few. Aim: To compare propofol and midazolam/meperidine sedation for UGE in terms of cardiopulmonary side effects, patient and endoscopist satisfaction and procedure-related times. Material and methods: This was a prospective, randomized, double-blind study of propofol versus midazolam and meperidine in 100 patients scheduled for diagnostic upper gastrointestinal endoscopy. The patients were divided into propofol and midazolam/meperidine groups. Randomization was generated by a computer. Cardiopulmonary side effects (hypotension, bradycardia, hypoxemia, procedure-related times (endoscopy time, awake time, time to hospital discharge, and patient and endoscopist satisfaction were compared between groups. Results: There was no significant difference between the groups with respect to the cost, endoscopy time, or demographic and clinical characteristics of the patients. Awake time and time to hospital discharge were significantly shorter in the propofol group (6.58 ±4.72 vs. 9.32 ±4.26 min, p = 0.030 and 27.60 ±7.88 vs. 32.00 ±10.54 min, p = 0.019. Hypotension incidence was significantly higher in the propofol group (12% vs. 0%, p = 0.027. The patient and endoscopist satisfaction was better with propofol. Conclusions : Propofol may be preferred to midazolam/meperidine sedation, with a shorter awake and hospital discharge time and better patient and endoscopist satisfaction. However, hypotension risk should be considered with propofol, and careful evaluation is needed, particularly in cardiopulmonary disorders.

Ultra-processed foods (UPF) consumption has increased over the last decades and is raising concerns about potential adverse health effects. Our objective was to assess the association between UPF consumption and four functional gastrointestinal disorders (FGIDs): irritable bowel syndrome (IBS), functional constipation (FC), functional diarrhea (FDh), and functional dyspepsia (FDy), in a large sample of French adults. We analyzed dietary data of 33,343 participants from the web-based NutriNet-Santé cohort, who completed at least three 24 h food records, prior to a Rome III self-administered questionnaire. Proportion (in weight) of UPF in the diet (UPFp) was computed for each subject. The association between UPFp quartiles and FGIDs was estimated by multivariable logistic regression. Participants included in the analysis were mainly women (76.4%), and the mean age was 50.4 (SD = 14.0) years. UPF accounted for 16.0% of food consumed in weight, corresponding to 33.0% of total energy intake. UPF consumption was associated with younger age, living alone, lower incomes, higher BMI, and lower physical activity level (all p < 0.0001). A total of 3516 participants reported IBS (10.5%), 1785 FC (5.4%), 1303 FDy (3.9%), and 396 FDh (1.1%). After adjusting for confounding factors, an increase in UPFp was associated with a higher risk of IBS ( a OR Q4 vs. Q1 [95% CI]: 1.25 [1.12-1.39], p-trend < 0.0001). This study suggests an association between UPF and IBS. Further longitudinal studies are needed to confirm those results and understand the relative impact of the nutritional composition and specific characteristics of UPF in this relationship.

Neurofibromatosis I may rarely predispose to pheochromocytoma and gastrointestinal stromal tumors. A 59-year-old woman with neurofibromatosis I presented with pheochromocytoma of the left adrenal gland. During surgery, 3 gastrointestinal stromal tumors adjacent to the stomach and small intestine were removed. Despite appropriate thrombosis prophylaxis, the patient died of a pulmonary embolus 2 days postoperatively. The second patient, a 55-year-old man with neurofibromatosis I and bilateral pheochromocytomas, had several small gastrointestinal stromal tumors adjacent to the jejunum during surgery. A review of the literature was conducted to identify patients with neurofibromatosis I with concurrence of pheochromocytoma and gastrointestinal stromal tumors and to define the specific clinical features of these patients. In addition to our 2 patients, 12 other cases of neurofibromatosis I with concomitant occurrence of pheochromocytomas and gastrointestinal stromal tumors have been reported. Pheochromocytomas had adrenal locations in all patients. Two of the 14 patients had a mixed pheochromocytoma/ganglioneuroma. In 4 of the 14 patients, gastrointestinal stromal tumors were located along the stomach. The gastrointestinal stromal tumors in our 2 patients showed no somatic mutations in KIT and PDGFRA genes. A pulmonary embolism was diagnosed in 4 patients. The simultaneous occurrence of pheochromocytoma and gastrointestinal stromal tumor should be considered in all patients with neurofibromatosis I presenting with an abdominal mass with symptoms suggestive of pheochromocytoma. Therefore, a pheochromocytoma should be excluded before a patient with neurofibromatosis I undergoes surgery for a gastrointestinal stromal tumor because an undiagnosed pheochromocytoma carries a high risk of life-threatening cardiovascular complications during surgery. Finally, this combination may be associated with an increased risk for thromboembolic events, but more studies are necessary to

Neuropilin-2 mediated β-catenin signaling and survival in human gastro-intestinal cancer cell lines.

Full Text Available NRP-2 is a high-affinity kinase-deficient receptor for ligands belonging to the class 3 semaphorin and vascular endothelial growth factor families. NRP-2 has been detected on the surface of several types of human cancer cells, but its expression and function in gastrointestinal (GI cancer cells remains to be determined. We sought to determine the function of NRP-2 in mediating downstream signals regulating the growth and survival of human gastrointestinal cancer cells. In human gastric cancer specimens, NRP-2 expression was detected in tumor tissues but not in adjacent normal mucosa. In CNDT 2.5 cells, shRNA mediated knockdown NRP-2 expression led to decreased migration and invasion in vitro (p<0.01. Focused gene-array analysis demonstrated that loss of NRP-2 reduced the expression of a critical metastasis mediator gene, S100A4. Steady-state levels and function of β-catenin, a known regulator of S100A4, were also decreased in the shNRP-2 clones. Furthermore, knockdown of NRP-2 sensitized CNDT 2.5 cells in vitro to 5FU toxicity. This effect was associated with activation of caspases 3 and 7, cleavage of PARP, and downregulation of Bcl-2. In vivo growth of CNDT 2.5 cells in the livers of nude mice was significantly decreased in the shNRP-2 group (p<0.05. Intraperitoneal administration of NRP-2 siRNA-DOPC decreased the tumor burden in mice (p = 0.01. Collectively, our results demonstrate that tumor cell-derived NRP-2 mediates critical survival signaling in gastrointestinal cancer cells.

The nutritional management of gastrointestinal tract disorders in companion animals.

Guilford, W G; Matz, M E

Dietary protein, carbohydrates, fats and fibre have marked influences on gastrointestinal tract function and dysfunction. This article reviews the nutritional management of common gastrointestinal disorders in companion animals and introduces some of the current areas of research including probiotics, prebiotics, protein-hydrolysate diets, immunonutrition and dietary fibre. Nutritional management of oesophageal disease revolves around varying the consistency of the diet and feeding the animal from an elevated container. Provision of bowel rest remains the mainstay of the management of acute gastroenteritis but food-based oral rehydration solutions are a useful adjunct. The recommended diet for chronic small bowel diarrhoea is a highly digestible, hypoallergenic, gluten-free, low-lactose and low-fat diet with modest amounts of fermentable fibre. The use of probiotics in the management of diarrhoea in companion animals has not yet been shown to be beneficial. It is likely that prebiotics will prove more effective than probiotics in the prevention of enteropathogenic infections. Approximately 50% of cats in New Zealand that suffer from chronic idiopathic vomiting or diarrhoea will respond to a novel-protein-elimination diet and approximately 30% meet the diagnostic criteria for food sensitivity. Growing evidence supports the use of protein-hydrolysate diets in the management of inflammatory bowel disease and further advances in immunonutrition are expected. The dietary management of colitis should include a hypoallergenic diet with a fermentable fibre source. Manipulation of the diet provides clinicians a powerful therapeutic strategy to be used alone or concurrently with drug therapy in the management of gastrointestinal disorders.

Owensby, Susan; Taylor, Kellee; Wilkins, Thad

2015-01-01

Upper gastrointestinal bleeding is an uncommon but potentially serious, life-threatening condition in children. Rapid assessment, stabilization, and resuscitation should precede all diagnostic modalities in unstable children. The diagnostic approach includes history, examination, laboratory evaluation, endoscopic procedures, and imaging studies. The clinician needs to determine carefully whether any blood or possible blood reported by a child or adult represents true upper gastrointestinal bleeding because most children with true upper gastrointestinal bleeding require admission to a pediatric intensive care unit. After the diagnosis is established, the physician should start a proton pump inhibitor or histamine 2 receptor antagonist in children with upper gastrointestinal bleeding. Consideration should also be given to the initiation of vasoactive drugs in all children in whom variceal bleeding is suspected. An endoscopy should be performed once the child is hemodynamically stable. © Copyright 2015 by the American Board of Family Medicine.

Effects of radiation upon gastrointestinal motility

Institute of Scientific and Technical Information of China (English)

Mary F Otterson

2007-01-01

Whether due to therapeutic or belligerent exposure, the gastrointestinal effects of irradiation produce symptoms dreaded by a majority of the population. Nausea, vomiting, diarrhea and abdominal cramping are hallmarks of the prodromal phase of radiation sickness, occurring hours to days following radiation exposure. The prodromal phase is distinct from acute radiation sickness in that the absorptive, secretory and anatomic changes associated with radiation damage are not easily identifiable. It is during this phase of radiation sickness that gastrointestinal motility significantly changes. In addition, there is evidence that motor activity of the gut contributes to some of the acute and chronic effects of radiation.

First Insights into the Diverse Human Archaeome: Specific Detection of Archaea in the Gastrointestinal Tract, Lung, and Nose and on Skin

Full Text Available Human-associated archaea remain understudied in the field of microbiome research, although in particular methanogenic archaea were found to be regular commensals of the human gut, where they represent keystone species in metabolic processes. Knowledge on the abundance and diversity of human-associated archaea is extremely limited, and little is known about their function(s, their overall role in human health, or their association with parts of the human body other than the gastrointestinal tract and oral cavity. Currently, methodological issues impede the full assessment of the human archaeome, as bacteria-targeting protocols are unsuitable for characterization of the full spectrum of Archaea. The goal of this study was to establish conservative protocols based on specifically archaea-targeting, PCR-based methods to retrieve first insights into the archaeomes of the human gastrointestinal tract, lung, nose, and skin. Detection of Archaea was highly dependent on primer selection and the sequence processing pipeline used. Our results enabled us to retrieve a novel picture of the human archaeome, as we found for the first time Methanobacterium and Woesearchaeota (DPANN superphylum to be associated with the human gastrointestinal tract and the human lung, respectively. Similar to bacteria, human-associated archaeal communities were found to group biogeographically, forming (i the thaumarchaeal skin landscape, (ii the (methanoeuryarchaeal gastrointestinal tract, (iii a mixed skin-gastrointestinal tract landscape for the nose, and (iv a woesearchaeal lung landscape. On the basis of the protocols we used, we were able to detect unexpectedly high diversity of archaea associated with different body parts.

The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobinupper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobingastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even

Abdominal pain predominant functional gastrointestinal diseases (AP-FGD) are commonly seen in the paediatric age group. It has significant impact on daily activities of affected children. Main objective of this study was to assess the health related quality of life (HRQoL) in children with AP-FGD. This was a cross sectional survey conducted in children aged 13-18 years, in four randomly selected schools in Western province of Sri Lanka. Data was collected using a previously validated, self-administered questionnaire. It had questions on symptoms, HRQoL and health care consultation. AP-FGD were diagnosed using Rome III criteria. A total of 1850 questionnaires were included in the analysis [males 1000 (54.1%), mean age 14.4 years and SD 1.3 years]. Of them, 305 (16.5%) had AP-FGD [irritable bowel syndrome = 91(4.9%), functional dyspepsia = 11 (0.6%), abdominal migraine = 37 (1.9%) and functional abdominal pain = 180 (9.7%)]. Lower HRQoL scores for physical (83.6 vs. 91.4 in controls), social (85.0 vs. 92.7), emotional (73.6 vs. 82.7) and school (75.0 vs. 82.5) functioning domains, and lower overall scores (79.6 vs. 88.0) were seen in children with AP-FGD (p abdominal pain (r = -0.24, p abdominal bloating and vomiting (p < 0.05). Children with AP-FGD have lower quality of life in all 4 domains. Those with severe symptoms have lower HRQoL. Approximately 28% of children with AP-FGD seek healthcare for their symptoms.

Full Text Available Streptococcus bovis is a Gram-positive bacterium causing serious human infections, including endocarditis and bacteremia, and is usually associated with underlying disease. The aims of the current study were to compare prevalence of the bacterium associated with malignant and nonmalignant gastrointestinal diseases and to determine the susceptibility of the isolated strains to different antimicrobial agents. The result showed that the prevalence of S. bovis in stool specimens from patients with malignant or with nonmalignant gastrointestinal diseases was statistically significant. This result may support the idea that there is correlation between S. bovis and the malignant gastrointestinal diseases.

Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

Full Text Available Eosinophilic gastrointestinal disorder is a rare disorder characterised by eosinophilic infiltration of the gastrointestinal tract. There are various gastrointestinal manifestations with eosinophilic ascites being the most unusual and rare presentation. Diagnosis requires high index of suspicion and exclusion of various disorders associated with peripheral eosinophilia. There are no previous case reports to suggest an association between eosinophilic gastrointestinal disorder and coeliac disease in adults. We report a case of eosinophilic ascites and gastroenteritis in a 30-year-old woman with a known history of coeliac disease who responded dramatically to a course of steroids.

Broccoli is a common vegetable recognized as a rich source of antioxidants. To date, research on the antioxidant properties of broccoli, predominantly conducted on extracts, has not considered the lesions of composition and this activity after gastrointestinal digestion. Here the stability of antioxidants during gastrointestinal digestion was evaluated in conjunction with the protective effects of broccoli sprouts (BS) against oxidative stress in human colon cells. The obtained data suggest that, among the biocompounds identified in BS, glucosinolates were mainly degraded under gastrointestinal digestion, while phenolics, particularly hydroxycinnamic acid derivatives, were the most resistant constituents. The antioxidant capacity of BS extract subjected to gastrointestinal digestion was similar to or higher than that determined for non-digested BS. Gastrointestinal digested BS extract exhibited reactive oxygen species (ROS)-inhibitory capacity in NCM460 human colon cells, with 1 mg mL(-1) showing an ROS clearance of 76.59%. A 57.33% reduction in oxidative DNA damage in NCM460 cells due to treatment with digested BS extract was observed. The results lend support to the possible application of BS as a rich source of antioxidants to improve the defensive system against oxidative stress in the human colon mucosa. © 2014 Society of Chemical Industry.

Full Text Available Objective: Gastrointestinal infections are one of the major health problems in developing countries. The present study aims to estimate the prevalence of gastrointestinal infections in Ouagadougou, the capital of Burkina Faso. Methods: A door-to-door survey of selected residents in Ouagadougou city was conducted. Of the Ouagadougou’s 30 districts, nine most populated ones were selected to the study. The residents of these districts have middle incomes as those of the secondary cite of Burkina Faso. Results: The overall prevalence of gastrointestinal infections in the 30 days prior to the interview was 77/491 (15.7%: among children 44/223 (19.7% and among adults 33/268 (12.3%. Diarrhea and abdominal pain were the most com­mon symptoms among 33 adult cases while diarrhea and vomiting were the most common among children. None of the cases were hospitalized and a stool sample was taken in three of 77 cases. Medication for gastrointestinal infections was received by 55% percent of adults and 77% of children. Conclusions: Our results shown that antibiotics with and without prescription were the most common medicine used. Washing hands before meals and boiling milk before drinking had a protective effect against gastrointestinal infections. J Microbiol Infect Dis 2016;6(2: 45-52

Full text: The aim of the study was to carry out a systematic review determining the accuracy of CT angiography in the diagnosis of acute gastrointestinal bleeding. A search of published work in Medline and manual searching of reference lists of articles was conducted. Studies were included if they compared CT angiography to a reference standard of upper gastrointestinal endoscopy, colonoscopy, angiography or surgery in the diagnosis of acute gastrointestinal bleeding. Eight published studies evaluating 129 patients were included. Data were used to form 2 x2 tables. Computed tomography angiography showed pooled sensitivity of 86% (95% confidence interval 78-92%) and specificity of 95% (95% confidence interval 76-100%), without showing significant heterogeneity (x 2 = 3.5, P=0.6) and (x 2 - 5.4, P = 0.6), respectively. Summary receiver operating characteristic analysis showed an area under the curve of 0.93. Computed tomography angiography is accurate in the diagnosis of acute gastrointestinal bleeding and can show the precise location and aetiology of bleeding, thereby directing further management. Strong recommendations for use of CT cannot be made from this review because of the methodological limitations and further large prospective studies are needed to define the role of CT in acute gastrointestinal bleeding.

GASTROINTESTINAL STROMAL TUMOR (GIST

Directory of Open Access Journals (Sweden)

Luigi eTornillo

2014-11-01

Full Text Available Gastrointestinal stromal tumors are the most frequent mesenchymal tumors of the gastrointestinal tract. The discovery that these tumors, formerly thought of smooth muscle origin, are indeed better characterized by specific activating mutation in genes coding for the receptor tyrosine kinases CKIT and PDGFRA and that these mutations are strongly predictive for the response to targeted therapy with receptor tyrosine kinase inhibitors has made GISTs the typical example of the integration of basic molecular knowledge in the daily clinical activity. The information on the mutational status of these tumors is essential to predict (and subsequently to plan the therapy. As resistant cases are frequently wild-type, other possible oncogenic events, defining other entities, have been discovered (e.g. succinil dehydrogenase mutation/dysregulation, insuline growth factor expression, mutations in the RAS-RAF-MAPK pathway. The classification of disease must nowadays rely on the integration of the clinico-morphological characteristics with the molecular data.

The scored Patient-Generated Subjective Global Assessment (PG-SGA) is considered to be the most appropriate tool for detecting malnutrition in cancer patients. In particular, malignant tumours derived from the gastrointestinal tract may impair nutrient intake and absorption and cause malnutrition. We carried out a cross-sectional study to assess the nutritional status and related factors of patients with gastrointestinal cancer. Nutritional status was determined using the scored PG-SGA in patients (n 498) with advanced gastrointestinal cancer admitted to the Gastrointestinal Medical Oncology Unit at Beijing Cancer Hospital between 1 August 2012 and 28 February 2013. The possible related factors including age, sex, hospitalisation frequency and pathology were explored. We found that 98% of the patients required nutrition intervention and 54% of the patients required improved nutrition-related symptom management and/or urgent nutritional support (PG-SGA score ≥9). Factors related to malnutrition were age (r 0.103, Pcancer had a lower risk of malnutrition than patients with other types of gastrointestinal cancer (F=35.895, Pnutritional status of gastrointestinal patients, especially those at a higher risk of malnutrition, such as elderly patients, those hospitalised for the first time, male patients and those with other types of gastrointestinal cancer except rectal cancer. The nutritional status of these patients should be evaluated and they should be given proper nutrition education and nutritional support in a timely manner.

To assess the efficacy of glucomannan (GNN) as the sole treatment for abdominal pain-related functional gastrointestinal disorders (FGIDs). We conducted a double-blind, placebo-controlled, randomized trial. Patients were recruited among children referred to the Department of Paediatrics, Medical University of Warsaw. Included in the study were children aged 7-17 years with abdominal pain-related FGIDs classified according to the Rome III diagnostic criteria. The children were randomly assigned to receive GNN, a polysaccharide of 1,4-D-glucose and D-mannose, a soluble fiber from the Japanese Konjac plant, at a dosage of 2.52 g/d (1 sachet of 1.26 g 2 times a day), or a comparable placebo (maltodextrin) at the same dosage. The content of each sachet was dissolved in approximately 125 mL of fluid and was consumed twice daily for 4 wk. Of the 89 eligible children, 84 (94%) completed the study. "No pain" and "treatment success" (defined as no pain or a decrease ≥ 2/6 points on the FACES Pain Scale Revised) were similar in the GNN (n = 41) and placebo (n = 43) groups [no pain (12/41 vs 6/43, respectively; RR = 2.1, 95%CI: 0.87-5.07) as well as treatment success (23/41 vs 20/43; RR = 1.2, 95%CI: 0.79-1.83)]. No significant differences between the groups were observed in the secondary outcomes, such as abdominal cramps, abdominal bloating/gassiness, episodes of nausea or vomiting, or a changed in stool consistency. GNN demonstrated no significant influence on the number of children requiring rescue therapy, school absenteeism, or daily activities. In our setting, GNN, as dosed in this study, was no more effective than the placebo in achieving therapeutic success in the management of FGIDs in children.

Upper and lower gastrointestinal symptoms are major and serious complications in patients who undergo chemotherapy for hematological malignancies. Their most frequent causes are acute intestinal graft-versus-host disease (GVHD) after bone marrow transplant, infections, toxicity or preexisting gastrointestinal diseases. Mortality can reach 30-60% of cases. We report 15 cases operated on for abdominal emergencies: 3 severe gastrointestinal bleeding and 12 acute abdomen. We performed 10 bowel resections, one cholecystectomy, one splenectomy, two laparotomy with pancreatic debridement and peritoneal lavage, and one suture of perforated peptic ulcer. Operative mortality was 33.3% (5/15). Deaths have been reported only in the group of patients with acute abdomen. In all cases death was correlated to generalized sepsis related to immunosuppression. We believe that an aggressive approach, consisting of close monitoring and early laparotomy combined with vigorous supportive therapy, should be used when dealing with suspected gastrointestinal complications in patients with hematological malignancies.

The management of gastrointestinal stromal tumors (GISTs) has evolved significantly in the last two decades due to better understanding of their biologic behavior as well as development of molecular targeted therapies. GISTs with exon 11 mutation respond to imatinib whereas GISTs with exon 9 or succinate dehydrogenase subunit mutations do not. Risk stratification models have enabled stratifying GISTs according to risk of recurrence and choosing patients who may benefit from adjuvant therapy. Assessing response to targeted therapies in GIST using conventional response criteria has several potential pitfalls leading to search for alternate response criteria based on changes in tumor attenuation, volume, metabolic and functional parameters. Surveillance of patients with GIST in the adjuvant setting is important for timely detection of recurrences.

Gastrointestinal absorption of plutonium was investigated in baboons after ingestion of plutonium solution (oxidation states III; IV; V; VI), and plutonium incorporated in soya bean and winkles. We studied the effects of oxidation state and ingested mass for masses ranging from 0.35 μg to 51.6 x 10 +3 μg (4 x 10 -2 to 7776 μg of plutonium per kg of body weight). No clear increase in plutonium retention was shown for concentrations of plutonium smaller than 1 μg/kg. From 1 μg/kg to 1 mg/kg no effects of mass or oxidation state was observed and the mean fractional retention value was 10 -4 . For ingested masses higher than 1 mg/kg the fractional retention values respectively increased for Pu(V) and Pu(III) to (0.9 + 0.2) x 10 -2 and (7.4 + 4.1) x 10 -4 of the ingested mass. This increase might be due to the weak hydrolysis of these oxidation states which would increase gastrointestinal absorption by decrease of hydroxide formation. The fraction of plutonium retained after ingestion of soya bean was (3.0 + 0.5) x 10 -4 about 3 fold higher than the value for 238 Pu nitrate solution. No clear increase in plutonium retention was shown after ingestion of winkles containing 238 Pu. In conclusion, except for high masses of ingested Pu, the retention of which could reach 1% of the ingested dose, our results show that the gastrointestinal transfer factor of 10 -4 proposed by ICRP for gastrointestinal absorption of soluble form of Pu is acceptable, but 10 -3 would provide better safety margin [fr

In response to the dearth of consumer health information for patients with gastrointestinal cancers, this study examined the informational needs of these patients to build a plan for future resource development. Although studies have examined informational needs of some such cancers, no published literature has investigated the comprehensive informational needs across all sites of gastrointestinal cancer. A cross-sectional needs assessment comprising a self-administered questionnaire was conducted at an ambulatory gastrointestinal oncology clinic in Toronto, Canada. Patient informational needs were measured, including importance of information, amount desired and preferred mode of delivery. Informational needs were grouped into six domains: medical, practical, physical, emotional, social and spiritual. Eighty-two surveys were analysed. The majority of the respondents were male (53.8%), over the age of 50 (77.8%), and born outside of Canada (51.9%). While many did not speak English as a child (46.3%), and do not speak English at home (22.2%), nearly all indicated comfort with receiving health information in English (97.5%). The majority of respondents were college educated (79.3%) and married (73%). Multiple cancer types were reported; the most common being colorectal (39%), followed by pancreatic (12%) and cancers of the gallbladder or bile duct (12%). Overall, respondents placed highest importance on medical information (P < 0.001). Preferred education modalities were pamphlets, websites and one-on-one discussions with health-care professionals. This study highlights the principal informational needs of patients with gastrointestinal malignancies, along with preferred modality for information delivery. This information will guide the development of educational resources for future patients. © 2014 John Wiley & Sons Ltd.

To evaluate the effectiveness of transcatheter embolization for the treatment of massive gastrointestinal arterial bleeding. The study was based on retrospective analysis of twelve cases(8 men, 4 woman) including two patients with hemobilia in which transcatheter embolization was attempted for the control of massive gastrointestinal bleeding from March 1987 to October 1993. Clinical diagnoses of these patients were peptic ulcer(5), pseudoaneurysm formation(3) following percutaneous transhepatic biliary drainage or traffic accident, stomach cancer(1), typhoid fever(1), duodenal leiomyoma(1) and Osler-Weber-Rendu disease (1). Embolized vessels are as follows: gastroduodenal artery(6), left gastric artery(2), ileocolic artery(2), and hepatic artery(2). Embolization was effective in immediate control of bleeding in all patients. Although five of the six patients who had undergone embolization of the gastroduodenal artery developed rebleeding within 24 hour, only 2 required surgery and none showed serious complication. Embolization therapy is safe and effective initial treatment of choice for life-threatening massive gastrointestinal bleeding

This is a retrospective analysis of interventional embolisation performed with catheter angiography in 29 patients with upper gastrointestinal bleeding in the setting of a secondary care hospital. From April 2007 to February 2013, 29 patients with upper gastrointestinal bleeding underwent endovascular diagnostics and treatment. The diagnosis was established by endoscopy, computed tomography or clinically based on a significant decrease in hemoglobin. Transcatheter arterial embolisation was performed with coils, liquid embolic agents, and particles. The technical and clinical outcomes were assessed by postinterventional endoscopy, hemoglobin concentrations, number of necessary transfusions, or surgical interventions, as well as by post-interventional mortality within 28 days after the procedure. Selective angiographic embolisation in upper gastrointestinal bleeding was primarily successful technically and clinically in 22 of 29 patients. In 4/29 cases an angiographic reintervention was performed, which was successful in 3 cases. In 3 cases of primarily technically unsuccessful procedures reintervention was not attempted. No catheterisation-related complications were recorded. Peri-interventional mortality was 31%, but only 2 of these patients died due to uncontrolled massive bleeding, whereas the lethal outcome in the other 7 patients was due to their underlying diseases. Transcatheter arterial embolisation is an effective and rapid method in the management of upper gastrointestinal bleeding. Radiological endovascular interventions may considerably contribute to reduced mortality in GI bleeding by avoiding a potential surgical procedure following unsuccessful endoscopic treatment. The study underlines the importance of the combination of interventional endoscopy with interventional radiology in secondary care hospitals for patient outcome in complex and complicated upper gastrointestinal bleeding situations. © Georg Thieme Verlag KG Stuttgart · New York.

Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

Full Text Available BACKGROUND: Children are vulnerable to a vast number of diseases including gastrointestinal disorders, which may be associated with life threatening complications that sometimes result in mortality especially if left untreated. OBJECTIVE: To establish the age and sex distribution of children in the study population as well as the histopathological characteristics of gastrointestinal diseases that occurred in those children who were aged 14years and below in Sagamu, Southwestern Nigeria. MATERIALS AND METHODS: Demographic data such as age, sex, and clinical summary of children in the study population were extracted from the medical records of Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State from January 2003 to December 2009. Based on this information, a review of paraffin embedded blocks and slides as well as histopathological reports of gastrointestinal diseases that occurred in those children aged 14years and below was undertaken at the Morbid Anatomy Department of the hospital. RESULTS: Seventy–four cases of gastrointestinal diseases were seen in children aged 14years and below. The majority (39.2% of gastrointestinal diseases were accounted for by appendiceal lesions. Hirschsprung’s disease, intussusceptions, enterocolitis and jejunal atresia accounted for 29.7%, 10.8%, 6.8% and 4.1% of cases respectively. Adenocarcinoma of the intestine was the predominant gastrointestinal tumour, occurring in 5 out of 7 children. Two cases of non-Hodgkin lymphoma were also seen. The ages of the children ranged from 2 to 14 years, with a mean age of 8.6years and a peak age incidence of gastrointestinal disease in the 10-14year age group. Male children were more commonly affected with the exception of appendiceal lesions, which occurred more in females (M:F ratio= 1.6:1.0. Acute suppurative appendicitis was the most prevalent lesion of the appendix, occurring in 13 out of 29 appendiceal lesions. Moderately differentiated to poorly

Cellular and Molecular Mechanisms of 3,3′-Diindolylmethane in Gastrointestinal Cancer

Soo Mi Kim

2016-07-01

Full Text Available Studies in humans have shown that 3,3′-diindolylmethane (DIM, which is found in cruciferous vegetables, such as cabbage and broccoli, is effective in the attenuation of gastrointestinal cancers. This review presents the latest findings on the use, targets, and modes of action of DIM for the treatment of human gastrointestinal cancers. DIM acts upon several cellular and molecular processes in gastrointestinal cancer cells, including apoptosis, autophagy, invasion, cell cycle regulation, metastasis, angiogenesis, and endoplasmic reticulum (ER stress. In addition, DIM increases the efficacy of other drugs or therapeutic chemicals when used in combinatorial treatment for gastrointestinal cancer. The studies to date offer strong evidence to support the use of DIM as an anticancer and therapeutic agent for gastrointestinal cancer. Therefore, this review provides a comprehensive understanding of the preventive and therapeutic properties of DIM in addition to its different perspective on the safety of DIM in clinical applications for the treatment of gastrointestinal cancers.

Regulation of UDP glucuronosyltransferases in the gastrointestinal tract

International Nuclear Information System (INIS)

Gregory, Philip A.; Lewinsky, Rikke H.; Gardner-Stephen, Dione A.; Mackenzie, Peter I.

2004-01-01

The UDP glucuronosyltransferases (UGT) of the gastrointestinal (GI) tract have a crucial role in protection against the toxic effects of lipophilic chemicals in the environment. UGTs such as UGT1A7, UGT1A8, and UGT1A10 are exclusively expressed in gastrointestinal tissues, each with a unique tissue distribution pattern that is subject to interindividual variation. The factors regulating this tissue-specific expression and that contribute to variability are beginning to be elucidated. Studies on the UGT1A7, 1A8, 1A9, and 1A10 gene promoters in Caco-2 cells, an in vitro model of enterocytes of the gastrointestinal tract, have identified the caudal homeodomain transcription factor, Cdx2, as an important regulator of the UGT1A8 and 1A10 gene proximal promoters. This transcription factor is found exclusively in the small intestine and colon: it is absent in the gastric epithelium and the esophagus. Cdx2 regulates the UGT1A8 and 1A10 promoters in cooperation with hepatocyte nuclear factor 1α (HNF1α). It is noteworthy that UGT1A7 is not expressed in gastrointestinal tissue distal to the gastric mucosa and does not contain a Cdx2 binding site in its proximal promoter. Transcription factors, including Sp1, which differentially bind to the initiator regions of the UGT1A8, 1A9, and 1A10 promoters, also contribute to the differences in expression of these UGTs in Caco-2 cells. The identification of important regulatory regions of UGT genes expressed in the gastrointestinal tract, and the transcription factors that bind to these regions, will aid in the elucidation of factors that contribute to interindividual differences in gastrointestinal UGT expression. In turn, this will lead to further understanding of interindividual variation in the capacity of the GI tract to metabolize lipophilic chemicals and to act as a barrier to dietary toxins and orally administered drugs

The emerging role of the microbial-gastrointestinal-neural axis

Directory of Open Access Journals (Sweden)

Peter G. McLean

2009-10-01

Full Text Available The gastrointestinal tract and its associated mucosal immune system have been extensively studied in the context of their involvement in disease processes, both within the tract itself and in its associated organs. However, historically a number of aspects of both gastrointestinal physiology and pathophysiology have been to some extent overlooked. In particular, the relationship of the gastrointestinal tract with its indigenous microbiota, and also the influence of the tract on behavior and neural systems and vice versa. Here, we describe recent advances in our knowledge and understanding of these areas, and attempt to put these advances in perspective with regard to potential therapeutic strategies.

The role of RI imaging in the diagnosis of lesions of the liver, biliary tracts and gastrointestinal tracts are reviewed, and representative cases are shown. Liver scintigraphy was of value for the diagnosis of lesions limitted to the liver such as primary and metastatic liver cancer and inflammatory liver diseases. However, RI methods were less useful in the diagnosis of lesions of the biliary tracts and stomach. RI scintigraphy was more sensitive than angiography in the detection of Meckel's deverticulum, Ballet's esophagus, and gastrointestinal hemorrhage. (Tsunoda, M.)

Short-term use of serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding.

The association between selective serotonin receptor inhibitors (SSRIs) and risk of upper gastrointestinal bleeding remains controversial. Previous studies have generally evaluated the issue for approximately 3 months, even though the SSRI-mediated inhibition of platelet serotonin concentrations occurs within 7-14 days. The authors explored the risk of upper gastrointestinal bleeding after short-term SSRI exposure by a case-crossover design. The records of psychiatric inpatients with upper gastrointestinal bleeding were retrieved from the Taiwan National Health Insurance Database (1998-2009). Rates of antidepressant use were compared for case and control periods with time windows of 7, 14, and 28 days. The adjusted self-matched odds ratios from a conditional logistic regression model were used to determine the association between SSRI use and upper gastrointestinal bleeding. A total of 5,377 patients with upper gastrointestinal bleeding were enrolled. The adjusted odds ratio for the risk of upper gastrointestinal bleeding after SSRI exposure was 1.67 (95% CI=1.23-2.26) for the 7-day window, 1.84 (95% CI=1.42-2.40) for the 14-day window, and 1.67 (95% CI=1.34-2.08) for the 28-day window. SSRIs with high and intermediate, but not low, affinity for serotonin transporter were associated with upper gastrointestinal bleeding. An elevated risk of upper gastrointestinal bleeding after SSRI exposure was seen in male but not female patients. Short-term SSRI use (7-28 days) is significantly associated with upper gastrointestinal bleeding. Gender differences may exist in the relationship between SSRI use and upper gastrointestinal bleeding. Physicians should carefully monitor signs of upper gastrointestinal bleeding even after short-term exposure to SSRIs, as is done with nonsteroidal anti-inflammatory drugs and aspirin.

Full Text Available Lower gastrointestinal bleeding is a common disease among elderly patients. The common sources of lower gastrointestinal bleeding include vascular disease, Crohn’s disease, neoplasms, inflammatory bowel disease, hemorrhoids, and ischemic colitis. Lower gastrointestinal bleeding arising from the appendix is an extremely rare condition. We report a case of appendiceal hemorrhage in a young male. Diagnosis was made by multidetector computerized tomography during survey for hematochezia. The patient recovered well after appendectomy. The histological finding revealed focal erosion of appendix mucosa with bleeding.

Heparin as a pharmacologic intervention to induce positive scintiscan in occult gastrointestinal bleeding

International Nuclear Information System (INIS)

Chaudhuri, T.K.; Brantly, M.

1984-01-01

The value of using heparin as a pharmacologic intervention to induce a positive scintiscan was studied in a patient with chronic occult gastrointestinal bleeding. When all standard diagnostic tests (upper and lower gastrointestinal series, upper and lower endoscopy, and conventional noninterventional Tc-99m RBC imaging) fail to detect and localize gastrointestinal bleeding in a patient who has definite clinical evidence (guaiac positive stool and dropping hemoglobin, hematocrit) of chronic occult gastrointestinal oozing, heparin may be used (with proper precaution) as a last resort to aid in the scintigraphic detection and localization of chronic occult gastrointestinal bleeding

The relationship between gastrointestinal motility and gastric dilatation-volvulus in dogs.

Science.gov (United States)

Gazzola, Krista M; Nelson, Laura L

2014-09-01

Gastric dilatation-volvulus (GDV) is a devastating disease that most commonly affects large and giant-breed dogs. Though a number of risk factors have been associated with the development of GDV, the etiology of GDV remains unclear. Abnormal gastric motility patterns and delayed gastric emptying have been previously described in dogs following GDV. Work evaluating the effects of gastropexy procedures and changes to gastric motility after experimental GDV has not found the same changes as those found in dogs with naturally occurring GDV. Although the role of abnormal gastric motility in dogs with GDV will need to be clarified with additional research, such study is likely to be facilitated by improved access to and development of noninvasive measurement techniques for the evaluation of gastric emptying and other motility parameters. In particular, the availability of Food and Drug Administration-approved wireless motility devices for the evaluation of gastrointestinal motility is particularly promising in the study of GDV and other functional gastrointestinal diseases of large and giant-breed dogs.

Reduction in heat-induced gastrointestinal hyperpermeability in rats by bovine colostrum and goat milk powders.

Science.gov (United States)

Prosser, C; Stelwagen, K; Cummins, R; Guerin, P; Gill, N; Milne, C

2004-02-01

Male Sprague-Dawley rats were assigned to one of three dietary groups [standard diet (Cont; n = 8), standard diet plus bovine colostrum powder (BColost 1.7 g/kg; n = 8), or goat milk powder (GMilk 1.7 g/kg; n = 8)] to determine the ability of these supplements to reduce gastrointestinal hyperpermeability induced by heat. Raising core body temperature of rats to 41.5 degrees C increased transfer of (51)Cr-EDTA from gut into blood 34-fold relative to the ambient temperature value (P transferred into the blood of rats in either the BColost (27% of Cont) or GMilk group (10% of Cont) after heating, showing that prior supplementation with either bovine colostrum or goat milk powder significantly reduced the impact of heat stress on gastrointestinal permeability. The changes in the BColost group were not significantly different than those of the GMilk group. The potential mechanism of the protective effect of bovine colostrum and goat milk powders may involve modulation of tight junction permeability, because both powders were able to maintain transepithelial resistance in Madin Darby canine kidney cells challenged with EGTA compared with cells maintained in media only. The results show that bovine colostrum powder can partially alleviate the effects of hyperthermia on gastrointestinal permeability in the intact animal. Moreover, goat milk powder was equally as effective as bovine colostrum powder, and both may be of benefit in other situations where gastrointestinal barrier function is compromised.

Neal Carlin

2014-01-01

Full Text Available Cocaine and its alkaloid free base “crack-cocaine” have long since been substances of abuse. Drug abuse of cocaine via oral, inhalation, intravenous, and intranasal intake has famously been associated with a number of medical complications. Intestinal ischemia and perforation remain the most common manifestations of cocaine associated gastrointestinal disease and have historically been associated with oral intake of cocaine. Here we find a rare case of two relatively uncommon gastrointestinal complications of hemorrhage and pancreatitis presenting within a single admission in a chronic crack cocaine abuser.

Upper gastrointestinal bleeding - state of the art.

Science.gov (United States)

Szura, Mirosław; Pasternak, Artur

2014-01-01

Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

Nuclear medicine methods used in diagnosing diseases of the gastrointestinal tract

International Nuclear Information System (INIS)

Kostadinova, I.

2001-01-01

Using physiologic tracer scintigraphy may give unique information on gastrointestinal (GI) motility and function, supplementing the findings of rather invasive methods. Conventional barium-contrast x-ray studies of the GI tract, computed tomography, ultrasonography and magnetic resonance imaging afford high resolution images of the GI anatomy, but have a serious shortcoming - hardly lending themselves to quantification. As shown by the results functional scintigraphy is a sensitive, quantitative and noninvasive procedure. The potential of nuclear medicine methods to diagnose successfully diseases of the salivary glands, esophagus, stomach and visualization of GI bleeding and hepatobiliary system are comprehensively discussed. The advantages and drawbacks of radionuclide techniques are outlined, and compared with other methods of visualization. (author)

Late effects of radiation therapy on the gastrointestinal tract

International Nuclear Information System (INIS)

Coia, Lawrence R.; Myerson, Robert J.; Tepper, Joel E.

1995-01-01

Late gastrointestinal complications of radiation therapy have been recognized but not extensively studied. In this paper, the late effects of radiation on three gastrointestinal sites, the esophagus, the stomach, and the bowel, are described. Esophageal dysmotility and benign stricture following esophageal irradiation are predominantly a result of damage to the esophageal wall, although mucosal ulcerations also may persist following high-dose radiation. The major late morbidity following gastric irradiation is gastric ulceration caused by mucosal destruction. Late radiation injury to the bowel, which may result in bleeding, frequency, fistula formation, and, particularly in small bowel, obstruction, is caused by damage to the entire thickness of the bowel wall, and predisposing factors have been identified. For each site a description of the pathogenesis, clinical findings, and present management is offered. Simple and reproducible endpoint scales for late toxicity measurement were developed and are presented for each of the three gastrointestinal organs. Factors important in analyzing late complications and future considerations in evaluation and management of radiation-related gastrointestinal injury are discussed

Gastrointestinal hormones and their targets

2014-01-01

Gastrointestinal hormones are peptides released from endocrine cells and neurons in the digestive tract. More than 30 hormone genes are currently known to be expressed in the gastrointestinal tract, which makes the gut the largest hormone producing organ in the body. Modern biology makes...... it feasible to conceive the hormones under five headings: The structural homology groups a majority of the hormones into nine families, each of which is assumed to originate from one ancestral gene. The individual hormone gene often has multiple phenotypes due to alternative splicing, tandem organization......, or differentiated maturation of the prohormone. By a combination of these mechanisms, more than 100 different hormonally active peptides are released from the gut. Gut hormone genes are also widely expressed in cells outside the gut, some only in extraintestinal endocrine cells and neurons but others also in other...

Investigation into the fungal diversity within different regions of the gastrointestinal tract of Panaque nigrolineatus, a wood-eating fish

Directory of Open Access Journals (Sweden)

Caroline L. Marden

2017-09-01

Full Text Available The Amazonian catfish, Panaque nigrolineatus have several physiological adaptions enabling the scraping and consumption of wood (xylivory, facilitating a detritivorous dietary strategy. Composed of lignocellulose, wood is a difficult substrate to degrade and as yet, it is unclear whether the fish obtains any direct nutritional benefits from wood ingestion and degradation. However, there are numerous systems that rely on microbial symbioses to provide energy and other nutritional benefits for host organisms via lignocellulose decomposition. While previous studies on the microbial community of P. nigrolineatus have focused upon the bacterial population, the role of fungi in lignocellulose degradation in the fish has not yet been examined. This study describes the detection of fungi within the fish gastrointestinal tract. Using next generation sequencing, the effects of diet on enteric fungal populations were examined in each gastrointestinal tract region. Fungal species were found to vary in different regions of the gastrointestinal tract as a function of diet. This study is the first to examine the fungal community in a xylivorous fish and results support the hypothesis that diet influences fungal distribution and diversity within the gastrointestinal tract of P. nigrolineatus.

5-HT in the enteric nervous system: gut function and neuropharmacology.

Science.gov (United States)

McLean, Peter G; Borman, Richard A; Lee, Kevin

2007-01-01

In recent times, the perception of functional gastrointestinal disorders such as irritable bowel syndrome (IBS) has shifted fundamentally. Such disorders are now thought of as serious diseases characterized by perturbations in the neuronal regulation of gastrointestinal function. The concept of visceral hypersensitivity, the characterization of neuronal networks in the 'brain-gut axis' and the identification of several novel 5-HT-mediated mechanisms have contributed to this shift. Here, we review how some of the more promising of these new mechanisms (e.g. those involving 5-HT transporters and the 5-HT(2B), 5-HT(7) and putative 5-HT(1p) receptors) might lead to a range of second-generation therapies that could revolutionize the treatment of functional gastrointestinal disorders, particularly IBS.

Poisoning due to chloroform ingestion is rare. The classic features of acute chloroform toxicity include central nervous system (CNS) and respiratory depression, and delayed hepatotoxicity. A 30-year-old female ingested 20-30 mL of 99% chloroform solution, which caused rapid loss of consciousness, transient hypotension and severe respiratory depression requiring endotracheal intubation and ventilation. She was alert by 12 h and extubated 16 h post-overdose. At 38-h post-ingestion, her liver function tests started to rise and she was commenced on intravenous acetylcysteine. Her alanine transaminase (1283 U/L), aspartate transaminase (734 U/L) and international normalized ratio (2.3) peaked 67- to 72-h post-ingestion. She also developed severe abdominal pain, vomiting and diarrhoea. An abdominal CT scan was consistent with severe enterocolitis, and an upper gastrointestinal endoscopy showed erosive oesophagitis, severe erosive gastritis and ulceration. She was treated with opioid analgesia, proton pump inhibitors, sucralfate and total parenteral nutrition. Secretions caused a contact dermatitis of her face and back. Nine days post-ingestion she was able to tolerate food. Her liver function tests normalized and the dermatitis resolved. Chloroform was measured using headspace gas chromatograph mass spectrometry, with a peak concentration of 2.00 μg/mL, 4 h 20 min post-ingestion. The concentration-time data fitted a 1-compartment model with elimination half-life 6.5 h. In addition to early CNS depression and delayed hepatotoxicity, we report severe gastrointestinal injury and dermatitis with chloroform ingestion. Recovery occurred with good supportive care, acetylcysteine and management of gastrointestinal complications.

The expanding regulatory universe of p53 in gastrointestinal cancer [version 1; referees: 2 approved

Directory of Open Access Journals (Sweden)

Andrew Fesler

2016-04-01

Full Text Available Tumor suppresser gene TP53 is one of the most frequently deleted or mutated genes in gastrointestinal cancers. As a transcription factor, p53 regulates a number of important protein coding genes to control cell cycle, cell death, DNA damage/repair, stemness, differentiation and other key cellular functions. In addition, p53 is also able to activate the expression of a number of small non-coding microRNAs (miRNAs through direct binding to the promoter region of these miRNAs.  Many miRNAs have been identified to be potential tumor suppressors by regulating key effecter target mRNAs. Our understanding of the regulatory network of p53 has recently expanded to include long non-coding RNAs (lncRNAs. Like miRNA, lncRNAs have been found to play important roles in cancer biology.  With our increased understanding of the important functions of these non-coding RNAs and their relationship with p53, we are gaining exciting new insights into the biology and function of cells in response to various growth environment changes. In this review we summarize the current understanding of the ever expanding involvement of non-coding RNAs in the p53 regulatory network and its implications for our understanding of gastrointestinal cancer.

Carabotti, Marilia; Lahner, Edith; Esposito, Gianluca; Sacchi, Maria Carlotta; Severi, Carola; Annibale, Bruno

2017-01-01

Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features.Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated.In total, 70.2% of patients were female, median age 55 years (range 17-83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

Synchronous Gastric Gastrointestinal Stromal Tumor and Colon Adenocarcinoma: A Case Report

2014-01-01

Full Text Available Gastrointestinal stromal tumors (GISTs represent the majority of primary mesenchymal tumors of the gastrointestinal tract. They are generally considered to be solitary tumors and therefore the synchronous occurrence with other primary malignancies of gastrointestinal track is considered a rare event. Here we present the case of a 75-year-old man admitted to our hospital with a 10-day history of gastrointestinal bleeding. Colonoscopy revealed an ulcerative mass of 4 cm in diameter in the ascending colon. Gastroscopy revealed a bulge in the gastric body measuring 1 cm in diameter with normal overlying mucosa. Surgical intervention was suggested and ileohemicolectomy with regional lymph node resection along with gastric wedge resection was performed. Pathologic examination of the ascending colon mass showed an invasive moderately differentiated adenocarcinoma stage III B (T3N1M0. Grossly resected wedge of stomach showed a well circumscribed intramural tumor which microscopically was consistent with essentially benign gastrointestinal stromal tumor (according to Miettinen criteria. The patient did not receive additional treatment. Two years later the patient showed no evidence of recurrence or metastasis.

Methods: 32 patients with acute or chronic gastrointestinal recurrent hemorrhage were examined. Among them, 26 patients had upper gastrointestinal hemorrhage and 6 with inferior gastrointestinal hemorrhage. All patients were under gone DSA and/or Puck angiography with Seldinger's technique. Results: The accuracy of localization was 84.38% (27/32) and the coincident rates with the operation or pathology was 78.95%(15/19). In all of patients, tumor of 9 case were shown and 15 cases of vascular diseases, namely, 9 with vascular malformation, 2 with small intestinal aneurysm, 3 with arteriosclerosis and 1 with broken gallbladder aneurysm; 3 cases of ulcer or nonspecific inflammation and 5 cases were negative. 23 cases (71.87%) showed the direct hemorrhagic sign, namely the contrast media extra vacation. Conclusions: Selective angiography is very helpful for determining the location and the character of unknown reasoned acute or chronic gastrointestinal hemorrhage, especially for the hemorrhage of the small intestine and biliary tracts

Summary A case of spinal epidural cavernous haemangioma associated with gastrointestinal haemangiomas is discussed. The patient was a young Chinese female presenting with chronic lower back pain. She had a history of extensive gastric and small bowel haemangiomas. Lumbar spine MRI showed a heterogeneously enhancing epidural mass infiltrating the paravertebral muscles. Open biopsy confirmed an epidural cavernous haemangioma. To our knowledge, an association between spinal epidural cavernous haemangiomas and gastrointestinal haemangiomas has not been reported.

Hypnosis Treatment of Gastrointestinal Disorders: A Comprehensive Review of the Empirical Evidence.

Science.gov (United States)

Palsson, Olafur S

2015-10-01

Hypnotherapy has been investigated for 30 years as a treatment for gastrointestinal (GI) disorders. There are presently 35 studies in the published empirical literature, including 17 randomized controlled trials (RCTs) that have assessed clinical outcomes of such treatment. This body of research is reviewed comprehensively in this article. Twenty-four of the studies have tested hypnotherapy for adult irritable bowel syndrome (IBS) and 5 have focused on IBS or abdominal pain in children. All IBS hypnotherapy studies have reported significant improvement in gastrointestinal symptoms, and 7 out of 10 RCTs in adults and all 3 RCTs in pediatric patient samples found superior outcomes for hypnosis compared to control groups. Collectively this body of research shows unequivocally that for both adults and children with IBS, hypnosis treatment is highly efficacious in reducing bowel symptoms and can offer lasting and substantial symptom relief for a large proportion of patients who do not respond adequately to usual medical treatment approaches. For other GI disorders the evidence is more limited, but preliminary indications of therapeutic potential can be seen in the single randomized controlled trials published to date on hypnotherapy for functional dyspepsia, functional chest pain, and ulcerative colitis. Further controlled hypnotherapy trials in those three disorders should be a high priority. The mechanisms underlying the impact of hypnosis on GI problems are still unclear, but findings from a number of studies suggest that they involve both modulation of gut functioning and changes in the brain's handling of sensory signals from the GI tract.

Castano LL, Rodrigo; Gaitan B, Maria H; Juliao E, Fabian

2005-01-01

Granular cells tumors are ubiquitous lesions in the gastrointestinal tract, are rare and asymptomatic and they are generally an incidental discovery at gastroduodenoscopy or colonoscopy. In the gastrointestinal tract they are more frequently located in the esophagus, right colon and rectum, stomach, appendix, small intestine or biliopancreatic tract. This article describes three patients with four tumors of granular cells in rectum, esophagus (2 lesions) and appendix. It becomes special emphasis in their neural origin, their benign behavior that justifies the endoscopic resections or limited surgical excisions and the necessity of a pursuit for the possibility, although little, of malignant transformation

Eating disorders which embrace anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified can be life-threatening due to general medical complications; however, the diagnosis of eating disorder is often delayed due to a low suspicion index. Gastroenterologists are health care providers who may come into contact with patients with undiagnosed eating disorders; it has been previously demonstrated that patients with eating disorders frequently have a significant association with functional dyspepsia. Signs of dental erosion have been described in patients with eating disorders; hence, they may help to identify eating disorders in patients who present with functional dyspepsia and deny having an eating disorder. In this report we describe three cases (a 25-year-old white woman, a 24-year-old white woman, and a 40-year-old white man) with undiagnosed eating disorders, in which a more comprehensive approach, such as the recognition of dental erosion joined with a careful gastrointestinal investigation, was performed to reach a final diagnosis of an eating disorder. The screening for dental erosion in patients seeking or receiving medical treatment for dyspeptic symptoms in a gastrointestinal out-patient clinic could be an aid for gastroenterologists to recognize the presence of an underlying eating disorder. A close collaboration with dentists, in addition to psychiatrists, could provide a more favorable treatment outcome.

Evaluations of upper gastrointestinal toxicity from ketamine abuse are uncommon. This study investigated the clinical pattern of upper gastrointestinal symptoms in patients inhaling ketamine. In a cross-sectional study of 611 consecutive patients who were seeking treatment for ketamine uropathy in a tertiary hospital setting between August 2008 and June 2016, their clinical pattern of upper gastrointestinal symptoms was evaluated and compared with a control population of 804 non-users. A total of 168 (27.5%) patients abusing ketamine (mean age 26.3 years, 58.9% female) reported the presence of upper gastrointestinal symptoms. These symptoms were significantly more prevalent in patients inhaling ketamine than in those who were not (27.5% vs 5.2%, P ketamine abuse before symptom presentation was 5.0 ± 3.1 years. The presenting symptoms included epigastric pain (n = 155, 25.4%), recurrent vomiting (n = 48, 7.9%), anemia (n = 36, 5.9%) and gastrointestinal bleeding (n = 20, 3.3%). Uropathy symptoms were preceded by upper gastrointestinal symptoms for 4.4 ± 3.0 years in 141 (83.9%) patients. Logistic regression showed that elder age (odds ratio [OR] 1.06, P = 0.04), active abuser status (OR 1.60, P = 0.04) and longer duration of ketamine abuse (OR 1.00, P = 0.04) were independent factors associated with upper gastrointestinal toxicity. Although epigastric symptoms are unusual in the young population, upper gastrointestinal toxicity was highly prevalent in those inhaling ketamine. Enquiries about ketamine abuse are recommended when assessing young patients with epigastric symptoms. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

The absorption and excretion of inorganic zinc, cadmium and mercury in the gastrointestinal tract were compared using /sup 65/Zn, /sup 109/Cd and /sup 203/Hg. A single dose of /sup 65/Zn, /sup 109/Cd or /sup 203/Hg was administered orally or injected intravenously to investigate the distribution, excretion into bile and excretion into feces or urine. Absorption and excretion through the gastrointestinal tract of mice were studied by the tied loop method. Groups of eight mice or rats were used to measure the radioactivity in sample with a scintillation counter. Most of the orally administered /sup 65/Zn, /sup 109/Cd or /sup 203/Hg was excreted into feces and was less absorbed by the gastrointestinal tract, respectively. Absorption rate in the gastrointestinal tract was as follows: /sup 203/Hg>/sup 65/Zn>/sup 109/Cd. Intravenously injected /sup 65/Zn, /sup 109/Cd or /sup 203/Hg was escreted into the gastrointestinal tract through the gastrointestinal wall and bile duct, respectively. Excretion rate in the gastrointestinal tract was as follows: /sup 65/Zn>/sup 203/Hg>/sup 109/Cd. When comparing the absorption and excretion in each gastrointestinal tract divided into 10 parts, /sup 65/Zn, and /sup 109/Cd were relatively well absorbed from the upper and lower part of small intestine and excreted into the upper, middle, lower part. /sup 203/Hg was relatively well absorbed from the upper, lower part of small intestine and excreted into the stomach and the caecum. The major organs that accumulated absorbed /sup 65/Zn, /sup 109/Cd or /sup 203/Hg were the pancreas and liver, liver and kidney, kidney and liver, respectively.

Behavioural medicine and gastrointestinal disorders: the promise of positive psychology.

Science.gov (United States)

Keefer, Laurie

2018-04-12

Psychosocial risk factors linked to brain-gut dysregulation are prevalent across the spectrum of gastrointestinal disorders and are associated with poor patient outcomes. Robust and reproducible data in the areas of behavioural intervention science and the brain-gut axis have led to major advances in patient care, including the routine use of brain-gut psychotherapies to manage digestive symptoms and optimize coping. The logical next step for the emerging field of psychogastroenterology is to develop a scientific framework that enables the identification of those individual characteristics and coping styles that buffer patients against the negative psychological effects of chronic gastrointestinal disorders. A shift towards a strength-based, positive psychological science of gastrointestinal disorders could facilitate the integration of early, effective psychological care into gastroenterology practice. In this Perspective, I discuss the potential role of three human strengths with relevance to gastrointestinal health - resilience, optimism and self-regulation - and how these three constructs can be cultivated through existing or emerging brain-gut psychotherapies.

Case presentation: The patient is a forty six years old man. He complained of frequent colic pain in left upper quadrant of abdomen for two months before admitting to the hospital. The pain resolved spontaneously after a few hours. This situation almost has been repeated every week. The patient had severe repeated melena and faint for two weeks. As soon as the patient was entered the Sina Hospital in 2012, supportive care was started. Then upper gastrointestinal endoscopy was performed for him and the bleeding point was detected. Also abdominal and pelvic computed tomography with oral and intravenous contrast was done. Finally the patient was operated on tumor diagnosis in duodenal area according to classic Whipple procedure. Conclusion: Gastrointestinal bleeding is the most common symptom of gastrointestinal stromal tumors. The bleeding is minimal and chronic. It will be progress to sudden and severe bleeding. Diagnosis is done by upper gastrointestinal endoscopy and biopsy. The large tumors with high mitotic

Full Text Available Gastrointestinal tumors are among the most common neoplastic causes of death worldwide. Presence of characteristic skin lesions can allow faster diagnosis and therapy and this way can increase the probability of a cure. In the paper we present the most important paraneoplastic syndromes that can coexist with gastrointestinal malignancy including colon, gastric, esophagus and pancreatic cancers. We take into account genetic syndromes such as Cowden syndrome, familial atypical multiple mole melanoma syndrome (FAMMM (melanoma/pancreatic cancer, Clarke Howel-Evans, Peutz-Jeghers, Muir-Torre, Gardner syndromes and acquired syndromes such as acantosis nigricans maligna, tripe palms, Leser-Trelat, Bazex, hypertrichosis languinosa, erythema gyratum repens , carcinoid and glucagonoma syndrome. We also include cutaneous metastases and coexistence of neoplasia in some cases of dermatomyositis.

Effects of berberine on a rat model of chronic stress and depression via gastrointestinal tract pathology and gastrointestinal flora profile assays.

Chronic stress and depression are challenging conditions to treat, owing to their complexity and lack of clinically available and effective therapeutic agents. The aim of the present study was to investigate the mechanism by which berberine acts, by examining alterations to gastrointestinal tract histopathology and flora profile in a rat model, following the induction of stress. Research associating gastrointestinal flora and depression has increased, thus, the present study hypothesized that stress induces depression and changes in the gastrointestinal system. The chronic mild stress rat model was previously established based on a set of 10 chronic unpredictable stress methods. In the present study, the measurements of body weight, behavior, gastrointestinal tract histopathology and gastrointestinal flora profile were collected in order to elucidate understanding of chronic stress and depression in this region. In the present study, induced stress and the resulting depression was demonstrated to significantly decrease the body weight and sucrose preference of rats, as well as significantly increasing traverse time, vertical movement time, grooming time and motionless time in an open‑field test. Following modeling and subsequent treatment with low or high doses of berberine, the measurements were significantly different when compared with unstressed rats. Berberine appears to reverse the physical damage brought about by stress within the gastric mucosa and intestinal microvilli of the stomach, ileum, cecum and colon. Using enterobacterial repetitive intergenic consensus sequence‑based polymerase chain reaction analysis, several distinctive bands disappeared following modeling; however, novel distinctive bands appeared in response to the graded berberine treatment. In conclusion, the present study identified that high concentrations of berberine markedly protects rats from various symptoms of chronic stress and depression, with the potential of facilitating

Excess Long-Term Mortality following Non-Variceal Upper Gastrointestinal Bleeding: A Population-Based Cohort Study

Crooks, Colin John; Card, Timothy Richard; West, Joe

2013-01-01

Background It is unclear whether an upper gastrointestinal bleed is an isolated gastrointestinal event or an indicator of a deterioration in a patient's overall health status. Therefore, we investigated the excess causes of death in individuals after a non-variceal bleed compared with deaths in a matched sample of the general population. Methods and Findings Linked longitudinal data from the English Hospital Episodes Statistics (HES) data, General Practice Research Database (GPRD), and Office of National Statistics death register were used to define a cohort of non-variceal bleeds between 1997 and 2010. Controls were matched at the start of the study by age, sex, practice, and year. The excess risk of each cause of death in the 5 years subsequent to a bleed was then calculated whilst adjusting for competing risks using cumulative incidence functions. 16,355 patients with a non-variceal upper gastrointestinal bleed were matched to 81,523 controls. The total 5-year risk of death due to gastrointestinal causes (malignant or non-malignant) ranged from 3.6% (≤50 years, 95% CI 3.0%–4.3%) to 15.2% (≥80 years, 14.2%–16.3%), representing an excess over controls of between 3.6% (3.0%–4.2%) and 13.4% (12.4%–14.5%), respectively. In contrast the total 5-year risk of death due to non-gastrointestinal causes ranged from 4.1% (≤50 years, 3.4%–4.8%) to 46.6% (≥80 years, 45.2%–48.1%), representing an excess over controls of between 3.8% (3.1%–4.5%) and 19.0% (17.5%–20.6%), respectively. The main limitation of this study was potential misclassification of the exposure and outcome; however, we sought to minimise this by using information derived across multiple linked datasets. Conclusions Deaths from all causes were increased following an upper gastrointestinal bleed compared to matched controls, and over half the excess risk of death was due to seemingly unrelated co-morbidity. A non-variceal bleed may therefore warrant a careful assessment of co

Bacterial Pollution in River Waters and Gastrointestinal Diseases

Full Text Available Currently, one of Mexico’s most severe environmental problems is the high levels of pollution of many of its rivers. The present article focuses on the relationship between total coliform bacteria levels and the increase of human digestive tract diseases in the highly polluted Atoyac River in the central Mexican states of Puebla and Tlaxcala. Pollution has become a potential health hazard for people living in nearby river communities. Based on data collected from six of the most contaminated riverside municipalities, two environmental models were developed taking into consideration the health of the entire population, not simply that of its individual members. Such models estimate a health-disease function that confirm the link between Atoyac River pollution and the incidence of gastrointestinal diseases. The causal relation between pollution and gastrointestinal disease incentivizes the creation of epidemiological and public health programs aimed at reducing the environmental health impact of the pollution associated with the Atoyac River. The results presented here are the first of their kind of this river and will serve as basis for future research exploring other similarly contaminated riparian communities. As the causes of pollution are directly related to the economic development and population growth of the region, further research should be conducted for prevention of diseases, educational programs, water remediation and conservation programs that will have a positive impact on the quality of life of the population presently at risk.

Full Text Available Abstract Background Differences between gastrointestinal and cardiovascular effects of traditional NSAID or cyclooxygenase-2 selective inhibitor (coxib are affected by drug, dose, duration, outcome definition, and patient gastrointestinal and cardiovascular risk factors. We calculated the absolute risk for each effect. Methods We sought studies with large amounts of information to calculate annualised rates for clearly defined gastrointestinal (complicated upper gastrointestinal perforations, ulcers, or bleeds, but not symptomatic or endoscopic ulcers and serious cardiovascular outcomes (antiplatelet trial collaborators – APTC – outcome of fatal or nonfatal myocardial infarction or stroke, or vascular death. Results Meta-analyses and large randomised trials specifically analysing serious gastrointestinal bleeding or cardiovascular events occurring with five different coxibs had appropriate data. In total there were 439 complicated upper gastrointestinal events in 49,006 patient years of exposure and 948 serious cardiovascular events in 99,400 patient years of exposure. Complicated gastrointestinal events occurred less frequently with coxibs than NSAIDs; serious cardiovascular events occurred at approximately equal rates. For each coxib, the reduction in complicated upper gastrointestinal events was numerically greater than any increase in APTC events. In the overall comparison, for every 1000 patients treated for a year with coxib rather than NSAID, there would be eight fewer complicated upper gastrointestinal events, but one more fatal or nonfatal heart attack or stroke. Three coxib-NSAID comparisons had sufficient numbers of events for individual comparisons. For every 1000 patients treated for a year with celecoxib rather than an NSAID there would be 12 fewer upper gastrointestinal complications, and two fewer fatal or nonfatal heart attacks or strokes. For rofecoxib there would be six fewer upper gastrointestinal complications, but three

Full Text Available Gastrointestinal stromal tumors (GISTs are the most common mesenchymal tumors of the gastrointestinal tract and are predominant in the stomach and intestine but rare in the esophagus. Here, we report a case of esophageal GIST which presented as a mediastinal mass on chest X-ray and dyspnea. The case was initially diagnosed as leiomyosarcoma, which could create a diagnostic dilemma. Therefore, recognizing this uncommon presentation as a mediastinal mass with esophageal GIST is important in the differential diagnosis.

Imaging of the abdomen for suspected gastrointestinal and hepatic disease during pregnancy is assuming greater importance. Like clinical evaluation, imaging of the abdomen and pelvis is challenging but is vitally important to prevent delayed diagnosis or unnecessary interventions. Also choice of imaging modality is influenced by factors which could impact on fetal safety such as the use of ionising radiation and magnetic resonance imaging. This article discusses important issues in imaging of gastrointestinal and hepatic disease in pregnancy and the puerperium.

Patient-reported outcome (PRO) measures of gastrointestinal symptoms are recommended to determine treatment effects for irritable bowel syndrome (IBS) and functional abdominal pain (FAP). Study objectives were to compare the symptom profiles of pediatric patients with IBS or FAP with healthy controls and with each other using the PedsQL Gastrointestinal Symptoms and Gastrointestinal Worry Scales, and to establish clinical interpretability of PRO scale scores through identification of minimal important difference (MID) scores. Gastrointestinal Symptoms and Worry Scales were completed in a 9-site study by 154 pediatric patients and 161 parents (162 families; IBS n = 46, FAP n = 119). Gastrointestinal Symptoms Scales measuring stomach pain, stomach discomfort when eating, food and drink limits, trouble swallowing, heartburn and reflux, nausea and vomiting, gas and bloating, constipation, blood in poop, and diarrhea were administered along with Gastrointestinal Worry Scales. A matched sample of 447 families with healthy children completed the scales. Gastrointestinal Symptoms and Worry Scales distinguished between patients with IBS or FAP compared with healthy controls (P 1.50) for symptoms indicative of IBS or FAP, demonstrating a broad multidimensional gastrointestinal symptom profile and clinical interpretability with MID scores for individual PRO scales. Patients with IBS manifested more symptoms of constipation, gas and bloating, and diarrhea than patients with FAP. Patients with IBS or FAP manifested a broad gastrointestinal symptom profile compared with healthy controls with large differences, indicating the critical need for more effective interventions to bring patient functioning within the range of healthy functioning.

Full Text Available Background and Objective: Increasing survivability of probiotics in low pH juices and in gastrointestinal conditions is important for probiotic food industry. Nanofibers can reinforce the structure of entrapment matrices protecting probiotics in harsh conditions. This study investigated pectin-based bionanocomposites improved with nanochitin, nanolignocellulose and bacterial nanocellulose to introduce a prebiotic gastrointestinal-resistant matrix for enhancing the survival of Bacillus coagulans as a probiotic.Material and Methods: The bionanocomposites with various compositions were designed using mixture design method. These were fabricated based on cross-linking of calcium ions with pectin for entrapment of Bacillus coagulans. The survivability of probiotic was evaluated at 4°C or 25°C over a 5-week storage in peach juice and under simulated gastrointestinal conditions.Results and Conclusion: The prebiotic score of the pectin-nanochitin-nanolignocellulose (50:25:25% w w-1 was determined as 1.36. The survivability of Bacillus coagulans entrapped within the pectin-nanochitin-nanolignocellulose matrix was ~65% under gastrointestinal treatment. The surface structure of the matrix was relatively smooth coherent, compact and wrinkled due to the three-dimensional arrangement of the nanofibers of chitin and lignocellulose incorporated within pectin. The highest survivability of the entrapped bacteria was ~68% compared to the survivability of the free cell (~53% at the end of 5-week storage period. After 21 day storage in the juice, the survivability of the entrapped bacteria treated under sequential digestion was ~58% as compared to that of the free cell (~43%. The present findings proposed a promising prebiotic matrix to protect probiotics in low pH fruit juice and the gastrointestinal tract.Conflict of interest: The authors declare no conflict of interest.

Management of radiation injuries of 10 cases of gastrointestinal tracts

Ten cases of delayed radiation injuries of the gastrointestinal tracts (consisting of 2 with peptic ulcer, 4 with intestinal obstruction, and 4 with rectal bleeding) are reported. Although conservative therapy or artificial colostomy was undertaken in all cases, satisfactory results were not obtained. In four cases in which subsequent resection of the gastrointestinal tracts was performed, the prognosis was favorable, but various symptoms still continued in the other non-resected cases. Delayed radiation injuries are progressive lesions involving the vasculo-connective tissue, so that cure can not be achieved. Resection of the damaged gastrointestinal tract is recommended, however, this is difficult to do in many cases. (Namekawa, K.).

Full Text Available CONTEXT Upper gastrointestinal bleeding (UGIB is one of the commonest gastrointestinal emergencies encountered by clinicians. Peptic ulcers are the most common cause of UGIB. Endoscopy has become the preferred method for diagnosis in patients with acute UGIB. This study is done in a diagnostic upper gastrointestinal endoscopy (UGIE setup of a tertiary care hospital to ascertain the causes of UGIB prevalent in this part of our country which might differ from other studies. AIM To ascertain prevalent causes of UGIB in patients of this part of India admitted to a Govt. Tertiary Hospital with a provisional diagnosis of UGIB. METHOD One hundred consecutive patients with UGIB were subjected to UGIE to find out the aetiology. The clinical profile and endoscopic findings were analysed and compared with the data on UGIB from other studies. RESULTS The mean age of patients was 47.03 years with male: female ratio of 2.33:1. 58% of patients were first time bleeders. Majority of patients presented with melaena. Visualisation of active bleeding achieved to 85.7% when endoscopy was done within first 24 hrs. The commonest cause of UGIB was duodenal ulcer (DU which accounted for 41% cases. Gastric ulcer was responsible in 13% of cases. Portal hypertension was responsible for bleed in only 13%. Neoplasms accounted for 25% of cases. Other less common causes were erosive gastritis (3%, gastric polyp (3%, Mallory-Weiss tear (1%, and Dieulafoy’s lesion (1%. Among bleeding peptic ulcers, 27.8% of cases were classified as Forrest IIa and 20.4% in Forrest IIb & IIc each. Acid peptic disease was past history elicited in majority (33% followed by NSAID (26% and alcohol (26%. CONCLUSION The present study has diagnosed various causes of upper gastrointestinal bleeding in this part of country. The incidence of gastric carcinoma as a cause of upper gastrointestinal bleeding is significantly high compared to those in other studies. UGI endoscopy should be done in every case

Acute gastrointestinal illness is an important public-health issue worldwide. Burden-of-illness studies have not previously been conducted in Cuba. The objective of the study was to determine the magnitude, distribution, and burden of self-reported acute gastrointestinal illness in Cuba. A retrospective, cross-sectional survey was conducted in three sentinel sites during June-July 2005 (rainy season) and during November 2005–January 2006 (dry season). Households were randomly selected from a list maintained by the medical offices in each site. One individual per household was selected to complete a questionnaire in a face-to-face interview. The case definition was three or more bouts of loose stools in a 24-hour period within the last 30 days. In total, 97.3% of 6,576 interviews were completed. The overall prevalence of acute gastrointestinal illness was 10.6%. The risk of acute gastrointestinal illness was higher during the rainy season (odds ratio [OR]=3.85, 95% confidence interval [CI] 3.18-4.66) in children (OR=3.12, 95% CI 2.24-4.36) and teens (OR=2.27, 95% CI 1.51-3.41) compared to people aged 25-54 years, in males (OR=1.24, 95% CI 1.04-1.47), and in the municipality of Santiago de Cuba (OR=1.33, 95% CI 1.11-1.61). Of 680 cases, 17.1-38.1% visited a physician, depending on sentinel site. Of the cases who visited a physician, 33.3-53.9% were requested to submit a stool sample, and of those, 72.7-100.0% complied. Of the cases who sought medical care, 16.7- 61.5% and 0-31.6% were treated with antidiarrhoeals and antibiotics respectively. Acute gastrointestinal illness represented a substantial burden of health compared to developed countries. Targeting the identified risk factors when allocating resources for education, food safety, and infrastructure might lower the morbidity associated with acute gastrointestinal illness. PMID:19507750

Studies of gastrointestinal function during sleep are hampered by lack of applicable techniques. Recent development of a novel ambulatory telemetric capsule system, which can be used in conjunction with polysomnography, offers a solution to this problem. The 3D-Transit system consists of ingestible electromagnetic capsules traceable through a portable extracorporeal receiver while traversing the gut. During sleep monitored by polysomnography, gastrointestinal motility was concurrently investigated using 3D-Transit in nine healthy subjects. Overall, the amplitude of gastric contractions decreased with depth of sleep (light sleep, N2 versus deep sleep, N3; P<0.05). Progression through the small intestine did not change with depth of sleep (Kruskal-Wallis probability =0.1), and there was no association between nocturnal awakenings or arousals and the occurrence of colonic or small intestinal propagating movements. Basal colonic activity was suppressed during both deep sleep (P<0.05) and light sleep (P<0.05) when compared with nocturnal wake periods. In conclusion, the novel ambulatory 3D-Transit system combined with polysomnography allows minimally invasive and completely ambulatory investigation of associations between sleep patterns and gastrointestinal motility.

Background and study aims  Rectosigmoidoscopy with biopsy has been regarded to be a useful procedure to diagnose gastrointestinal graft-versus-host disease (GVHD). However, little is known about the specific colonoscopic features of gastrointestinal GVHD. In this study, we focused on the 4 unique colonoscopic findings – orange peel appearance, spotty redness, small mucosal sloughing, and diffuse mucosal defect – which are possible specific findings of gastrointestinal GVHD. We aimed to estimate the usefulness of these four unique colonoscopic findings in the rectosigmoid portion to diagnose gastrointestinal GVHD. Patients and methods  Seventy patients who were histologically diagnosed with gastrointestinal GVHD at our institute were retrospectively enrolled. Colonoscopic findings were reviewed, focusing on the four characteristic findings. The percentage of the positive cases for the characteristic findings was calculated. The final scoping portion and the number of cases showing any of the four characteristic findings in the rectosigmoid portion were also evaluated. The relationships between biopsy sites and the histological findings were also evaluated. Results  Orange peel appearance was observed in 66 cases (94.3 %). Spotty redness was observed in 45 cases (64.3 %). Small mucosal sloughing was observed in 49 cases (70.0 %). Diffuse mucosal defect was observed in six cases (8.6 %). The number of cases that were concurrently positive for one, two, and three findings were 16 (20.8 %), 20 (26.0 %), and 34 (48.6 %), respectively. Fifty-eight cases (82.9 %) were investigated up to the rectosigmoid portion, and 12 (17.1 %) were investigated beyond the sigmoid colon. All of the cases showed at least 1 of the 4 characteristics in the rectosigmoid portion. The percentage of crypt apoptosis in the biopsy specimen from orange peel appearance, spotty redness, small mucosal sloughing, and diffuse mucosal defect were 87.5 %, 83.3 %, 87.2�

Gastrointestinal and nutritional problems in neurologically impaired children.

2016-11-01

The current increasing survival of children with severe central nervous system damage has created a major challenge for medical care. Gastrointestinal and nutritional problems in neurologically impaired children have been recently recognized as an integral part of their disease, often leading to growth failure and worsened quality of life for both children and caregivers. Nutritional support is essential for the optimal care of these children. Undernourished handicapped children might not respond properly to intercurrent diseases and suffer unnecessarily. On the other hand, restoring a normal nutritional status results in a better quality of life in many. The easiest and least invasive method to increase energy intake is to improve oral intake. However, oral intake can be maintained as long as there is no risk of aspiration, the child is growing well and the time required to feed the child remains within acceptable limits. When oral intake is unsafe, insufficient or too time consuming, enteral nutrition should be initiated. Damage to the developing central nervous system may result in significant dysfunction in the gastrointestinal tract and is reflected in impairment in oral-motor function, rumination, gastro-oesophageal reflux (GER), with or without aspiration, delayed gastric emptying and constipation. These problems can all potentially contribute to feeding difficulty in disabled children, carrying further challenging long-term management issues.

Full Text Available Aim: Students are subjected to different kinds of stressors, such as the pressure of academics with an obligation, an uncertain future and difficulties of integrating into the system. Although nursing and midwifery students experience a high level of stress during their training, there has been limited research on stress and its impact on the student's physical responses, such as gastrointestinal symptoms. The aims of this study are to assess the prevalence of gastrointestinal symptoms in nursing and midwifery students and to examine the association between the perceived stress and gastrointestinal symptoms. Methods: This performed using cross-sectional descriptive study design study enrolled a total of 449 students participates in the study in a university degree program was carried out on 366 nursing and midwifery students accepted. A personal information questionnaire, Perceived Stress Scale and a Gastrointestinal Symptoms Questionnaire were administered through a self-reported system. Results: Seventy point two percent of the nursing and midwifery students experienced at least one gastrointestinal symptom, with 35.8% of students reporting at least three gastrointestinal symptoms. Most of the nursing and midwifery students complained of upper dysmotility and bowel symptoms. In addition, students who reported higher perceived stress were significantly more likely to complain of gastrointestinal symptoms. Compared to students with the lowest perceived stress level, the adjusted odds ratio for gastrointestinal symptoms in students with the highest perceived stress level was 6.45 times higher. Conclusions: Gastrointestinal symptoms that are highly prevalent among nursing and midwifery students are significantly associated with the perceived stress level. High perceived stress should be considered a risk factor for gastrointestinal symptoms. Based on the study findings, there is a critical need of instructing the nursing and midwifery students

Gastrointestinal tract duplication is a rare malformation associated with the presence of additional segment of the fetal gut. The aim of this study was to retrospectively review clinical features and imaging findings in intraoperatively confirmed cases of gastrointestinal tract duplication in children. The analysis included own material from the years 2002-2012. The analyzed group included 14 children, among them 8 boys and 6 girls. The youngest patient was diagnosed at the age of three weeks, and the oldest at 12 years of age. The duplication cysts were identified in the esophagus (n=2), stomach (n=5), duodenum (n=1), terminal ileum (n=5), and rectum (n=1). In four cases, the duplication coexisted with other anomalies, such as patent urachus, Meckel's diverticulum, mesenteric cyst, and accessory pancreas. Clinical manifestation of gastrointestinal duplication cysts was variable, and some of them were detected accidently. Thin- or thick-walled cystic structures adjacent to the wall of neighboring gastrointestinal segment were documented on diagnostic imaging. Ultrasound and computed tomography are the methods of choice in the evaluation of gastrointestinal duplication cysts. Apart from the diagnosis of the duplication cyst, an important issue is the detection of concomitant developmental pathologies, including pancreatic heterotopy.

Radiological diagnosis of gastrointestinal bleeding

Neufang, K.F.R.; Gross-Fengels, W.; Lorenz, R.

1990-01-01

In the diagnosis of acute gastrointestinal bleeding, endoscopy holds the first place today. Radiological investigations are indispensable whenever endoscopy cannot precisely localise the bleeding site, whenever a tumour is present or suspected, in all cases of lower gastrointestinal bleeding, and in haemobilia. A tailored radiological approach is recommended. The radiological basis programme should be at least a complete abdominal ultrasound study and plain abdominal radiograms. CT and ERCP scans may become necessary in selected cases. As a rule, angiographical localisation of the bleeding site will be successful only in the acute stage; selective visceral arteriograms have to be obtained, which may be executed in the digital subtraction technique in patients who are cooperating and clinically stable. Angiodysplasias and aneurysms, however, may be demonstrated angiographically in the interval as well. Upper and/or lower G.I. tract studies with barium or water-soluble contrast media may be indicated in the interval in order to demonstrate tumours, metastatic lesions, diverticula and gut malformations.

The purpose of this study was to assess the usefulness of helical CT in depicting the location of acute lower gastrointestinal bleeding. A three-phase helical CT of the abdomen was performed in 24 patients referred for acute lower gastrointestinal bleeding. The diagnosis of the bleeding site was established by CT when there was at least one of the following criteria: spontaneous hyperdensity of the peribowel fat; contrast enhancement of the bowel wall; vascular extravasation of the contrast medium; thickening of the bowel wall; polyp or tumor; or vascular dilation. Diverticula alone were not enough to locate the bleeding site. The results of CT were compared with the diagnosis obtained by colonoscopy, enteroscopy, or surgery. A definite diagnosis was made in 19 patients. The bleeding site was located in the small bowel in 5 patients and the colon in 14 patients. The CT correctly located 4 small bowel hemorrhages and 11 colonic hemorrhages. Diagnosis of the primary lesion responsible for the bleeding was made in 10 patients. Our results suggest that helical CT could be a good diagnostic tool in acute lower gastrointestinal bleeding to help the physician to diagnose the bleeding site. (orig.)

Chimeric peptide MCRT, based on morphiceptin and PFRTic-NH 2 , was a bifunctional ligand of μ- and δ-opioid receptors (MOR-DOR) and produced potent analgesia in tail-withdrawal test. The study focused on the supraspinal effects of morphiceptin, PFRTic-NH 2 and MCRT on gastrointestinal motility. Moreover, opioid receptor antagonists, naloxone (non-selective), cyprodime (MOR selective) and naltrindole (DOR selective) were utilized to explore the mechanisms. Intracerebroventricular administration was achieved via the implanted cannula. Gastric emptying and intestinal transit were measured to evaluate gastrointestinal motility. (1) At supraspinal level, morphiceptin, PFRTic-NH 2 and MCRT significantly decreased gastric emptying and intestinal transit; (2) MCRT at 1 nmol/mouse, far higher than its analgesic dose (ED 50  = 29.8 pmol/mouse), failed to regulate the gastrointestinal motility; (3) MCRT-induced gastrointestinal dysfunction could be completely blocked by naloxone and naltrindole, but not affected by cyprodime. (1) Morphiceptin and PFRTic-NH 2 played important roles in the regulation of gastrointestinal motility; (2) MCRT possessed higher bioactivity of pain relief than gastrointestinal regulation, suggesting its promising analgesic property; (3) MCRT-induced motility disorders were sensitive to DOR but not to MOR blockade, indicating the pain-relieving specificity of speculated MOR subtype or splice variant or MOR-DOR heterodimer. © 2017 Royal Pharmaceutical Society.

The purpose of this study is to present controversial point and reform measurements by analysing factors having important effect on selection of upper gastrointestinal study in total health promotion. We examined 200 persons for this study, who visited for upper gastrointestinal study from January to February in 1999. We classified this group into Endoscopy, Upper gastrointestinal series, and sleeping endoscopy. We also investigated standard of satisfaction and factors having effect on selection of each study. As is results, in the motive of selection, Item of 'making accurate observation' and 'without pain' was 39.3% and 34.7%, respectively. In this study, sleeping endoscopy was 45.7%, but on the other side upper gastrointestinal series was low 22.6%(P<0.05). In the standard of preference of study, the man was 55.7% in the endoscopy, and the woman was 61.8% in the upper gastrointestinal series(P<0.05). The standard of preference of upper gastrointestinal series show that it was satisfied on the whole irrespective of sex, dwelling place, age, occupation, and level of education. In the selection of study, one's own will was showed the highest frequency, and family inducement was showed second(P<0.05). Persons over 60% were examined before the same study. Selection of upper gastrointestinal series was 47.9% of person with normal findings, and endoscopy and sleeping endoscopy was over 70% with gastritis, gastric and duodenal(P<0.01). For one's accurate selection of examination, it is important that objective and credible information should be given to a recipient for examination

DOG1, a Ca 2+ -activated Cl − channel (CaCC), was identified in 2004 to be robustly expressed in gastrointestinal stromal tumors (GIST). It was rapidly included as a tumor marker in routine diagnostics, but the functional role remained unknown. CaCCs are important regulators of normal physiological functions, but also implicated in tumorigenesis, cancer progression, metastasis, cell migration, apoptosis, proliferation and viability in several malignancies. We therefore investigated whether DOG1 plays a role in the three latter in GIST by utilizing in vitro cell model systems. Confocal microscopy identified different subcellular localizations of DOG1 in imatinib-sensitive and imatinib-resistant cells. Electrophysiological studies confirmed that DOG1-specific pharmacological agents possess potent activating and inhibiting properties. Proliferation assays showed small effects up to 72 h, and flow cytometric analysis of adherent cells with 7-AAD/Annexin V detected no pharmacological effects on viable GIST cells. However, inhibition of DOG1 conveyed pro-apoptotic effects among early apoptotic imatinib-resistant cells. In conclusion, DOG1 generates Cl − currents in GIST that can be regulated pharmacologically, with small effects on cell viability and proliferation in vitro. Inhibition of DOG1 might act pro-apoptotic on some early apoptotic GIST cell populations. Further studies are warranted to fully illuminate the function of DOG1 and its potential as therapeutic target. - Highlights: • Subcellular DOG1 localization varies between GIST cells. • DOG1 in GIST is voltage- and Ca 2+ -activated. • Known TMEM16A modulators, like A01 and Eact, modulate DOG1. • DOG1 has small effects on cell viability and proliferation in vitro. • DOG1 impact early apoptotic GIST cells to undergo late apoptosis

Working irregular shift patterns is associated with functional constipation among healthy trainee nurses

2017-11-01

Full Text Available The circadian system has a role in regulating gastrointestinal physiology. Perturbation of this system is associated with gastrointestinal tract dysfunction. Shiftwork and poor sleep quality are associated with functional gastrointestinal disorders among many professional groups. This study compared bowel habits between trainee nurses with regular and irregular patterns of shiftwork. Male and female nursing students, enrolled on the first year (regular shifts; n=49 and the fourth year (irregular shifts, n=48 of a nursing degree course were surveyed. Questionnaires were used to assess functional diarrhea and constipation over a three month period. The prevalence of functional constipation among regular shift workers was lower than that found among irregular shift workers; 31.3% and 61.2%, respectively. There was no difference between the two groups in relation to the prevalence of diarrhea. This suggests an association between shiftwork and functional constipation, but not with functional diarrhea.

Gastrointestinal involvement in vasculitis may result in life-threatening complications. However, its variable clinical presentations and endoscopic features, and the rarity of the disease, often result in delayed diagnosis. Clinical characteristics, endoscopic features, and histopathological findings were reviewed from medical records. Of 6,477 patients with vasculitis, 148 were diagnosed as primary vasculitis with upper gastrointestinal involvement. Of these, 21 cases (14.2%) were classified as large-vessel vasculitis, 17 cases (11.5%) as medium-vessel vasculitis, and 110 cases (74.3%) as small-vessel vasculitis. According to the specific diagnosis, IgA vasculitis (Henoch-Schönlein purpura) was the most common diagnosis (56.8%), followed by Takayasu arteritis (14.1%), microscopic polyangiitis (10.1%), and polyarteritis nodosa (6.8%). Gastrointestinal symptoms were present in 113 subjects (76.4%), with abdominal pain (78.8%) the most common symptom. Erosion and ulcers were striking endoscopic features, and the second portion of the duodenum was the most frequently involved site. Biopsy specimens were obtained from 124 patients, and only eight (5.4%) presented histopathological signs of vasculitis. Diagnosis of vasculitis involving the upper gastrointestinal tract is difficult. Because of the widespread use of endoscopy, combining clinical features with endoscopic findings may facilitate making appropriate diagnoses; however, the diagnostic yield of endoscopic biopsy is low.

Targeting cancers in the gastrointestinal tract: role of capecitabine

Full Text Available Muhammad Wasif SaifYale Cancer Center, Yale University School of Medicine, New Haven, CT, USAAbstract: Capecitabine is currently the only novel, orally home-administered fluorouracil prodrug. It offers patients more freedom from hospital visits and less inconvenience and complications associated with infusion devices. The drug has been extensively studied in large clinical trials in many solid tumors, including breast cancer, colorectal cancer, gastric cancer, and many others. Furthermore, the drug compares favorably with fluorouracil in patients with such cancers, with a safe toxicity profile, consisting mainly of gastrointestinal and dermatologic adverse effects. Whereas gastrointestinal events and hand-foot syndrome occur often with capecitabine, the tolerability profile is comparatively favorable. Prompt recognition of severe adverse effects is the key to successful management of capecitabine. Ongoing and future clinical trials will continue to examine, and likely expand, the role of capecitabine as a single agent and/or in combination with other anticancer agents for the treatment of gastrointestinal as well as other solid tumors, both in the advanced palliative and adjuvant settings. The author summarizes the current data on the role of capecitabine in the management of gastrointestinal cancers.

To assess the appearance of gastrointestinal melanoma metastases on CT and PET/CT and evaluate the diagnostic value of CT and PET/CT compared with surgery and histopathology. We retrospectively included 41 consecutive patients (aged 56.1 ± 13.5 years) with gastrointestinal melanoma metastases who underwent preoperative imaging (CT: all, PET/CT: n = 24) and metastasectomy. Two blinded radiologists assessed CT and PET/CT for gastrointestinal metastases and complications. Diagnostic accuracy and differences regarding lesion detectability and complications were assessed, using surgical findings and histopathology as standard of reference. Fifty-three gastrointestinal melanoma metastases (5.0 ± 3.8 cm) were confirmed by surgery and histopathology. Lesions were located in the small bowel (81.1 %), colon (15.1 %) and stomach (3.8 %), and described as infiltrating (30.2 %), polypoid (28.3 %), cavitary (24.5 %) and exoenteric (17.0 %). Fifteen patients (37 %) had gastrointestinal complications. Higher complication rates were associated with large and polypoid lesions (p ≤.012). Diagnostic accuracy was high for CT and PET/CT (AUC ≥.802). For reader B (less experienced), CT yielded lower diagnostic accuracy than PET/CT (p =.044). Most gastrointestinal melanoma metastases were located in the small bowel. Large and polypoid metastases were associated with higher complication rates. PET/CT was superior for detection of gastrointestinal melanoma metastases and should be considered in patients with limited disease undergoing surgery. (orig.)

Gastrointestinal disorders cause morbidity and can lead to mortality, especially in the developing world where sanitation is deficient. A large part of the human population relies on medicinal plants for treating various diseases, including gastrointestinal disorders. The present review summarizes the traditional uses of medicinal plants of Nepal used to treat gastrointestinal disorders, and evaluates their bio-efficacy based on a review of the available phytochemical and pharmacological literature. We searched different electronic databases and libraries for the literature on medicinal plants used in Nepal to treat gastrointestinal disorders. For each species, we also searched the literature for information on conservation status, as well as for phytochemical and pharmacological studies in support of the ethnobotanical information. We used principal component analysis to explore the relation among disorders and plant families, plant life forms, plant parts and preparation modes. We also performed permutation tests to determine if botanical families were used more often than expected considering their availability in the Nepali flora. We documented a total of 947 species belonging to 158 families and 586 genera used to treat gastrointestinal disorders in Nepal. Diarrhea was the disorder treated by the highest number of species (348), followed by stomachache (340) and dysentery (307). Among the reported species, five were endemic to Nepal, whereas 16 orchid species were protected under CITES Appendices II and III. The randomization test showed that species belonging to 14 families were used less often than expected, whereas plants belonging to 25 families were used more often than expected. The PCA scatter plot showed distinct groups of gastrointestinal disorders treated with similar plant life forms, plant parts, and/or preparation modes. We found 763 phytochemical studies on 324 species and 654 pharmacological studies on 269 species. We showed the diversity and

Full Text Available Introduction: Ramadan is the ninth month of Muslim's calendar during which Muslims fast. Ramadan lasts 29-30 days based on the visual sightings of the crescent moon. Fasting during Ramadan has significant health effects. The present study aimed at reviewing the literature of the impact of Ramadan fasting on upper gastrointestinal disorders. Methods: MEDLINE and Google Scholar were searched  by using ((“Ramadan” R   fasting” AND( "Upper Gastrointestinal Tract" OR "Gastrointestinal Diseases" OR "Dyspepsia" OR "Gastroesophageal Reflux"  OR "Peptic Ulcer" OR "Gastrointestinal Hemorrhage" as keywords in the title and abstract. Relevant, non- duplicate full articles written in English were reviewed. Results: Gastric acid and pepsin secretion increase during Ramadan fasting, probably associated with dyspeptic symptoms. Regarding peptic ulcer frequency, results are inconsistent. However, peptic ulcer complications such as gastrointestinal bleeding and peptic ulcer perforation increase during Ramadan fasting. Conclusion: Fasting during Ramadan seems to be beneficial for healthy individuals, but in people with gastrointestinal disorders, it might be harmful as it increases the risk of complications. Therefore, taking medical advice before Ramadan fasting is highly recommended to people suffering from gastrointestinal symptoms.

Upper gastrointestinal bleeding refers to bleeding that arises from the gastrointestinal tract proximal to the ligament of Treitz. The primary reason for gastrointestinal bleeding associated with hepatocellular carcinoma is rupture of a varicose vein owing to pericardial hypotension. We report a rare case of gastrointestinal bleeding with hepatocellular carcinoma in a patient who presented with recurrent gastrointestinal bleeding. The initial diagnosis was gastric cancer with metastasis to the multiple lymph nodes of the lesser curvature. The patient underwent exploratory laparotomy, which identified two lesions in the gastric wall. Total gastrectomy and hepatic local excision was then performed. Pathological results indicated that the hepatocellular carcinoma had invaded the stomach directly, which was confirmed immunohistochemically. The patient is alive with a disease-free survival of 1 year since the surgery. Hepatocellular carcinoma with gastric invasion should be considered as a rare cause of upper gastrointestinal bleeding in hepatocellular carcinoma patients, especially with lesions located in the left lateral hepatic lobe. Surgery is the best solution.

Strain-resolved microbial community proteomics reveals simultaneous aerobic and anaerobic function during gastrointestinal tract colonization of a preterm infant

Directory of Open Access Journals (Sweden)

Full Text Available While there has been growing interest in the gut microbiome in recent years, it remains unclear whether closely related species and strains have similar or distinct functional roles and if organisms capable of both aerobic and anaerobic growth do so simultaneously. To investigate these questions, we implemented a high-throughput mass spectrometry-based proteomics approach to identify proteins in fecal samples collected on days of life 13-21 from an infant born at 28 weeks gestation. No prior studies have coupled strain-resolved community metagenomics to proteomics for such a purpose. Sequences were manually curated to resolve the genomes of two strains of Citrobacter that were present during the later stage of colonization. Proteome extracts from fecal samples were processed via a nano-2D-LC-MS/MS and peptides were identified based on information predicted from the genome sequences for the dominant organisms, Serratia and the two Citrobacter strains. These organisms are facultative anaerobes, and proteomic information indicates the utilization of both aerobic and anaerobic metabolisms throughout the time series. This may indicate growth in distinct niches within the gastrointestinal tract. We uncovered differences in the physiology of coexisting Citrobacter strains, including differences in motility and chemotaxis functions. Additionally, for both Citrobacter strains we resolved a community-essential role in vitamin metabolism and a predominant role in propionate production. Finally, in this case study we detected differences between genome abundance and activity levels for the dominant populations. This underlines the value in layering proteomic information over genetic potential.

To describe the abdominal imaging findings of patients with gastrointestinal Basidiobolus ranarum infection. A literature search was performed to compile the abdominal imaging findings of all reported worldwide cases of gastrointestinal basidiobolomycosis (GIB). In addition, a retrospective review at our institution was performed to identify GIB cases that had imaging findings. A radiologist aware of the diagnosis reviewed the imaging findings in detail. Additional information was obtained from the medical records. A total of 73 GIB cases have been published in the medical literature. The most common abdominal imaging findings were masses in the colon, the liver, or multiple sites and bowel wall thickening. Initially, many patients were considered to have either a neoplasm or Crohn disease. We identified 7 proven cases of GIB at our institution, of which 4 had imaging studies (4 computed tomography [CT] examinations, 4 abdominal radiographs, and an upper gastrointestinal study). Imaging studies showed abnormalities in all 4 cases. Three-fourths of our study patients had an abdominal mass at CT. Two of 3 masses involved the kidneys and included urinary obstruction. All masses showed an inflammatory component with adjacent soft tissue stranding, with or without abscess formation. Radiologists should consider GIB when a patient from an arid climate presents with abdominal pain, weight loss, and an inflammatory abdominal mass on CT. Abdominal masses of the colon or liver, bowel wall thickening, and abscesses are the most common imaging findings.

During recent years, knowledge gaps on drinking water-related gastrointestinal illness have been identified, especially for non-epidemic cases. Pathogen contamination of drinking water during distribution has been suggested to contribute to these cases, but the risk factors are not yet fully understood. During 2014-2015, we conducted an epidemiological study in five municipalities in Sweden, to assess whether incidents in the drinking water distribution system influence the risk of gastrointestinal illness. Telephone interviews were conducted in the affected areas and in reference areas 7-14 days after a reported incident. Symptoms of gastrointestinal illness occurring during the period were documented for each household member. The results showed a significantly elevated risk of vomiting and acute gastrointestinal illness (AGI) in the affected areas, compared to the reference areas (OR vom.  = 2.0, 95% CI: 1.2-3.3; OR AGI  = 1.9, 95% CI: 1.2-3.0). Certain conditions, or risk factors, during the incidents, such as sewage and drinking water pipelines at the same level in the trench, were associated with an elevated risk of AGI and vomiting. Safety measures taken during repair work, like flushing, were also associated with an elevated risk of AGI and vomiting. These results show that incidents in the drinking water distribution network contribute to endemic gastrointestinal illness, especially AGI and vomiting, and that external pathogen contamination of the drinking water is a likely cause of these cases of gastrointestinal illness. The results also indicate that safety measures used today may not be sufficient for eliminating the risk of gastrointestinal illness. Copyright © 2017 The Authors. Published by Elsevier Ltd..

The purpose of this study is to present controversial point and reform measurements by analysing factors having important effect on selection of upper gastrointestinal study in total health promotion. We examined 200 persons for this study, who visited for upper gastrointestinal study from January to February in 1999. We classified this group into Endoscopy, Upper gastrointestinal series, and sleeping endoscopy. We also investigated standard of satisfaction and factors having effect on selection of each study. As is results, in the motive of selection, Item of 'making accurate observation' and 'without pain' was 39.3% and 34.7%, respectively. In this study, sleeping endoscopy was 45.7%, but on the other side upper gastrointestinal series was low 22.6%(P<0.05). In the standard of preference of study, the man was 55.7% in the endoscopy, and the woman was 61.8% in the upper gastrointestinal series(P<0.05). The standard of preference of upper gastrointestinal series show that it was satisfied on the whole irrespective of sex, dwelling place, age, occupation, and level of education. In the selection of study, one's own will was showed the highest frequency, and family inducement was showed second(P<0.05). Persons over 60% were examined before the same study. Selection of upper gastrointestinal series was 47.9% of person with normal findings, and endoscopy and sleeping endoscopy was over 70% with gastritis, gastric and duodenal(P<0.01). For one's accurate selection of examination, it is important that objective and credible information should be given to a recipient for examination.

To investigate the influential factors on congenital gastrointestinal malformation and to provide evidences for prevention. A hospital-based case-control study was conducted among infants with or without congenital gastrointestinal malformation at Children's hospital of Hunan province, from April 2011 to August 2012. Parents of 120 cases with congenital gastrointestinal malformation and another 170 controls were asked to fill in a questionnaire. Data was analyzed using SPSS 18.0 software. Congenital gastrointestinal malformation was associated with intakes of maternal medication (OR = 3.35, 95%CI:1.51-7.41) and folic acid (OR = 0.28, 95%CI:0.15-0.52), exposure to paints (OR = 5.05, 95%CI:1.32-19.29) and pesticides (OR = 15.20, 95%CI:1.55-148.99) prior to or during pregnancy, and also associated with medication intake of the father (OR = 3.70, 95% CI:1.13-12.10), smoking (OR = 2.39, 95% CI:1.24-4.62), drinking alcohol (OR = 2.47, 95% CI:1.20-5.07), exposure to the agents for indoor cleaning (OR = 16.42, 95% CI:1.71-157.92) and exposure to paints (OR = 9.92, 95% CI:2.66-36.98) before conception. Congenital gastrointestinal malformation was affected by multiple factors. Potential risk factors for congenital gastrointestinal malformation would include intakes of medication by the pregnant mother, exposure to paints exposure and pesticide exposure before or during pregnancy, and medication intake by the father, smoking, drinking alcohol, exposure to indoor cleaning agents/paint before conception. The amount of folic acid intake by mother before or during pregnancy was likely to reduce the risk for congenital gastrointestinal malformation.

Full Text Available Nanotechnology is the understanding, control of matter and development of engineered devices in nanometer range (1-100 nm. Nanoparticles have different physicochemical properties (small size, large surface area to volume ratio, and high reactivity in comparison to bulk materials of the same composition. The nanotechnology has proved its usefulness in early diagnosis, proteonomics, imaging diagnostics and multifunctional therapeutics. Recent studies have shown its role in early diagnosis and targeted therapy of various gastrointestinal disorders such as hepatitis B virus and hepatitis C virus related liver disease, inflammatory bowel disease, gastric ulcer, and malignancy. Application of this technology appears promising in diagnostic and therapeutic endoscopy such as the endoscopic hemostasis of peptic ulcer bleeding, prevention of clogging of plastic stent and advance capsule endoscopy. This article will highlight the basic concepts of nanotechnology and its potential application in gastrointestinal endoscopy.

Studies of gastrointestinal function during sleep are hampered by lack of applicable techniques. Recent development of a novel ambulatory telemetric capsule system, which can be used in conjunction with polysomnography, offers a solution to this problem. The 3D-Transit system consists of ingestible electromagnetic capsules traceable through a portable extracorporeal receiver while traversing the gut. During sleep monitored by polysomnography, gastrointestinal motility was concurrently investigated using 3D-Transit in nine healthy subjects. Overall, the amplitude of gastric contractions decreased with depth of sleep (light sleep, N2 versus deep sleep, N3; P<0.05). Progression through the small intestine did not change with depth of sleep (Kruskal–Wallis probability =0.1), and there was no association between nocturnal awakenings or arousals and the occurrence of colonic or small intestinal propagating movements. Basal colonic activity was suppressed during both deep sleep (P<0.05) and light sleep (P<0.05) when compared with nocturnal wake periods. In conclusion, the novel ambulatory 3D-Transit system combined with polysomnography allows minimally invasive and completely ambulatory investigation of associations between sleep patterns and gastrointestinal motility.

The gastrointestinal symptoms accompanying dysfunction of the remnant stomach were seen after pylorus-preserving operation. Against such complications, Dai-kenchu-to (DKT) is used, but scientific evidences for efficacy are poor. The effect of DKT on gastrointestinal motility and gastric emptying after pylorus-preserving operation was investigated. Using beagle dogs, the experimental models mimicking the state after pylorus-preserving pancreaticoduodenectomy were prepared. We sutured strain gauge transducers to the stomach, duodenum and jejunum and inserted indwelling tubes into the stomach. About 4 weeks after operation, DKT 0.1g/kg was administered during the fasting or fed state. At the same time, the gastric emptying was evaluated by the acetoaminophene method. In the fasting state, administration of DKT enhanced the gastrointestinal motility and accelerated gastric emptying. In the postprandial state, no apparent effect on motility was seen. DKT enhances the gastrointestinal motility after pylorus-preserving pancreaticoduodenectomy in the fasting state. The effect of DKT may not be related to the continuity of the intramural nerve.

Gastrointestinal stromal tumors (GIST) are mesenquimal tumors derived from cell precursors. They have the capacity for myogenic and neurogenic differentiation and are characterized by expression of KIT protein (tyrosine kinase growth factor). Clinically, they exhibit various biological behaviors. We present 8 cases of GIST, describing both their radiological manifestation through computerized tomography (CT) and most accepted criteria for benignity and malignancy. We also describe the response of one meta statically diagnosed tumor to tyrosine kinase inhibitor. (Author) 9 refs.

Gastrointestinal Motility Variation and Implications for Plasma Level Variation: Oral Drug Products.

The oral route of administration is still by far the most ubiquitous method of drug delivery. Development in this area still faces many challenges due to the complexity and inhomogeneity of the gastrointestinal environment. In particular, dosing unpredictably relative to motility phase means the gastrointestinal environment is a random variable within a defined range. Here, we present a mass balance analysis that captures this variation and highlights the effects of gastrointestinal motility, exploring what impacts it ultimately has on plasma levels and the relationship to bioequivalence for high solubility products with both high and low permeability (BCS I and III). Motility-dependent compartmental absorption and transit (MDCAT) mechanistic analysis is developed to describe the underlying fasted state cyclical motility and how the contents of the gastrointestinal tract are propelled.

In order to clarify the validity of indication criteria of the conservative treatment for perforated upper gastrointestinal tract, a retrospective study was carried out. We enrolled 28 patients with perforation of the gastrointestinal tract who were determined to receive conservative treatment at the time of hospitalization from January 2000 to December 2007. When the following criteria were satisfied, we treated the patients by the conservative treatment after informed consent was gained from them and their families: stable condition of vital signs; peritoneal signs localized in the upper abdomen; and no or slight fluid collection at the Douglas' pouch determined by computed tomography. Patients who showed changes for the worse of peritonitis or increased fluid collection during follow-up were promptly converted to surgery. Six patients were converted to surgery, but all of them were discharged very much improved. We compared patient's data of the conservative treatment group and the converted surgery group at the time of consultation. All data were not statistically different between two groups. If all criteria are satisfied, it seemed that we can start conservative treatment for perforated gastrointestinal tract with careful observation and the system of prompt conversion to operation for patients who showed changes for the worse of peritonitis or increased fluid collection.

Full Text Available Abstract Background Radiomicrosphere therapy (RT utilizing yttrium-90 (90Y microspheres has been shown to be an effective regional treatment for primary and secondary hepatic malignancies. We sought to determine a large academic institution's experience regarding the extent and frequency of gastrointestinal complications. Methods Between 2004 and 2007, 27 patients underwent RT for primary or secondary hepatic malignancies. Charts were subsequently reviewed to determine the incidence and severity of GI ulceration. Results Three patients presented with gastrointestinal bleeding and underwent upper endoscopy. Review of the pretreatment angiograms showed normal vascular anatomy in one patient, sclerosed hepatic vasculature in a patient who had undergone prior chemoembolization in a second, and an aberrant left hepatic artery in a third. None had undergone prophylactic gastroduodenal artery embolization. Endoscopic findings included erythema, mucosal erosions, and large gastric ulcers. Microspheres were visible on endoscopic biopsy. In two patients, gastric ulcers were persistent at the time of repeat endoscopy 1–4 months later despite proton pump inhibitor therapy. One elderly patient who refused surgical intervention died from recurrent hemorrhage. Conclusion Gastrointestinal ulceration is a known yet rarely reported complication of 90Y microsphere embolization with potentially life-threatening consequences. Once diagnosed, refractory ulcers should be considered for aggressive surgical management.

The clinical features of 10 African patients with gastro-intestinal phytobezoars are described. These were similar to those described with persimmon bezoars and we postulate that the fruit of locally found trees, also of the genus Diospyros, are responsible.

Conventional methods, including radiopaque markers, scintigraphy, and PillCam™ involve radiation or require the child to swallow a large pill. The minimally invasive, radiation-free Motility Tracking System-1 (MTS-1 has been introduced for description of gastrointestinal motility in adults. The aim of the study was to evaluate the MTS-1 for assessment of gastrointestinal transit times and motility patterns in healthy children. Methods: Twenty-one healthy children (nine girls, median age 10 (range 7–12 years were included. For evaluation with MTS-1, a small magnetic pill was ingested and tracked through the gastrointestinal tract by a matrix of 16 magnetic sensors placed behind a nonmagnetic bed. The children were investigated for 8 hours after swallowing the magnetic pill and again for 4 hours the following morning. After leaving the unit, each child came back after every bowel movement to determine if the pill had been expelled. Results: Nineteen children could swallow the pill. Characteristic contraction patterns were identified for the stomach (three per minute, small intestine (9–11 per minute, and colon (4–5 per minute. Median total gastrointestinal transit time was 37.7 (range 9.5–95.8 hours, median gastric emptying time was 37 (range 2–142 minutes, median small intestinal transit time was 302 (range 164 to >454 minutes, and median colorectal transit time was 38.1 (range 5.6–90.0 hours. Conclusion: MTS-1 allows minimally invasive evaluation of gastrointestinal motility in

Objective: To investigate and assess the efficiency and clinical value of interventional therapy for gastrointestinal hemorrhage induced by Dieulafoy disease. Methods: Ten patients definitely diagnosed with Dieulafoy disease suffering from massive acute gastrointestinal hemorrhage received celiac arterial and left gastric arterial angiography, outcoming with 8 positively and 2 negative cases. Among them, 6 were embolized with gelfoam particles and the other two with aneurismal dilatation received gelfoam particles and spring steel coils; and one of the negtive cases was given hypophysin and without intervention to the other. Results: Among the 8 intra-arterial embolized cases, only 1 case rebleeded on the third day after gelfoam embolization, and then treated by surgical operation, and the rest 7 showed no rebleeding. One case with hypophysin treatment rehabilitated after one week. Conclusions: Interventional therapeutics is a safe and effective emergency management for gastrointestinal hemorrhage induced by Dieulafoy disease. (authors)

To evaluate the radiographic findings of gastrointestinal anisakiasis with clinical and pathologic correlation. In ten patients, findings were retrospectively analysed. There were two cases of the gastric variety of gastrointestinal anisakiasis and eight of the intestinal, and they were diagnosed during gastroscopy, by resection during surgery, and on the basis of typical clinical findings. All ten patients underwent both plain radiography and CT scanning of the abdomen. US was performed in five patients and an upper gastrointestinal series in one. Clinical data were evaluated with regard to a history of raw fish ingestion, time from ingestion of raw fish to onset of symptoms, location of abdominal pain, and laboratory data. Radiologic findings were analysed in terms of wall thickening and appearance, mesenteric infiltration, bowel dilatation proximal to lesion, and ascites. All patients had a history of recent ingestion of raw fish and complained of severe abdominal pain that occurred approximately 7-48 hours later. Pain occurred in the lower abdomen in five patients, the epigastrium in four, and the right lower abdomen in two. Laboratory test disclosed the leukocytosis in eight patients and eosinophilia in three. In all cases of intestinal anisakiasis, ileus was demonstrated on plain radiographs of the abdomen, while the upper gastrointestinal series showed mucosal thickening and multiple filling defects. US findings were bowel thickening and dilation, and on CT images, wall thickening revealed a target sign. Mesenteric infiltration and ascites were seen in seven patients. In four who underwent surgery, a cross-section through the lesion revealed submucosal eosinophilic granuloma with anisakis larva. Although the CT findings are non-specific, taken in conjunction with characteristic clinical findings, they may be helpful in the diagnosis of gastrointestinal anisakiasis. (author)
