Filter by:An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.
A feasibility study for monitoring and recording gastrointestinal (GI) myoelectric activity in subjects with suspected or diagnosed irritable bowel syndrome (IBS) and reports of GI pain and asymptomatic subjects without IBS and GI pain.
The objective of this study is to evaluate the efficacy and safety of a Chinese herbal proprietary medicine, MaZiRenWan (MZRW), by comparing with stimulant laxative western medicine (WM), senna, and placebo for patients with functional constipation (FC) in excessive TCM syndrome.
Various digestive manifestations are common in infants less than 6 months and have a significant impact on morbidity and quality of life of the family. In a prospective study on more than 2800 Italian infants followed by 0-6 months of life, it was determined that 55% of these children had gastrointestinal symptoms such as regurgitation (23%), colics (20%), constipation (17%) or poor weight gain (15%). However, these symptoms are not very accurate, and their cause is often difficult to determine. Frequently, the pediatrician will exclude cow's milk protein in infant feeding, but without a clear etiological diagnosis was asked. This measure causes significant additional costs through the use of extensively hydrolyzed milk specifically for children and involves an elimination diet of all foods containing cow's milk sometimes for several years. This can negatively influence the growth of the child. If the involvement of milk in these pathologies is suggested by some early studies (35% for colics, 68% in constipation, 42% in gastroesophageal reflux), it is unclear in the current state of knowledge if these gastrointestinal symptoms are actually due to an "allergy" to milk. Moreover, there is no validated diagnostic test for non-IgE-mediated gut allergy. However, various tests have proven their effectiveness in the investigation of non IgE-mediated allergy (eg. LAT, patch tests) and will be used in this study.
The purpose of this research study is to help us learn if children with Autism Spectrum Disorder (ASD) have gastrointestinal (stomach and intestine) problems more frequently than children without ASD do. The investigators hope to learn if children with ASD and gastrointestinal (GI) disorders have certain Problem Behaviors (PB), such as self-injury and aggression, more than children with ASD but no GI disorders do. The investigators want to learn if the Gastrointestinal Symptoms Questionnaire (GIQ) can help us tell which children with ASD also have gastrointestinal disorders. Hypothesis 1: Children with ASD exhibit high rates of symptomatic GI dysfunction that are not identified by current diagnostic evaluation. Hypothesis 2: Painful or discomfort-causing gastrointestinal dysfunctions contribute to an elevated incidence or severity of PB in an identifiable subpopulation of PB-expressing children. The investigators anticipate that the proposed study will raise the standard of medical care for children with ASD by improving current methods of identifying GI dysfunction and determining whether there is a significant relationship between GI dysfunction and PB in this population.
The aim was to study whether probiotic intervention has an impact on seasonal occurrence of upper respiratory and gastrointestinal infections in two different conscript groups. In a randomised, double-blinded, placebo controlled study a total of 983 healthy adults were enrolled from two intakes of conscripts. Conscripts were randomised to receive either a probiotic combination of Lactobacillus rhamnosus GG (LGG) and Bifidobacterium animalis ssp. lactis BB12 (BB12) or a control chewing tablet twice daily for 150 days (recruits) or for 90 days (reserve officer candidates). Clinical examinations were carried out and daily symptom diaries were collected. Outcome measures were the number of days with respiratory and gastrointestinal symptoms and symptom incidence, number and duration of infection episodes, number of antibiotic treatments received and number of days out of service because of the infection. Statistically no significant differences were found between the intervention groups either in the risk of symptom incidence or duration. However, probiotic intervention was associated with reduction of specific respiratory infection symptoms in military recruits, but not in reserve officer candidates. Probiotics did not significantly reduce overall respiratory and gastrointestinal infection morbidity.
Background: - Gastrointestinal diseases and disorders affect the throat, stomach, and intestines. There are many different kinds of these diseases. Clinical trials are being developed to study new ways to treat them. People who are interested in clinical trials need to be screened before they can take part in the studies. Researchers want to evaluate people with different stomach and intestine disorders to see if they are eligible for clinical trials. Objectives: - To study people who have gastrointestinal disorders and see if they are eligible for clinical trials. Eligibility: - Individuals at least 18 years of age who have or may have a gastrointestinal disorder. Design: - Participants will be screened with a physical exam and medical history. Blood, urine, and stool samples will be collected. Imaging studies such as x-rays and ultrasound will check to see if the disorder has affected other organs. - Participants may have tests as needed depending on their disorder. These tests include the following: - Colonoscopy and endoscopy of the large intestine, esophagus, and stomach. - Stomach acid analysis to look at stomach pH levels. - Wireless capsule endoscopy to take pictures of the small intestine. - Hydrogen breath testing to study issues like bloating, diarrhea, and constipation. - Sitz Marker Study to see how fast stool moves through the colon. - Participants may donate extra blood, urine, or stool samples for study. They may also donate stomach contents or tissue from the gut. - Treatment will not be provided as part of this study. However, participants may be admitted to other clinical trials.
The purpose of this study is to calculate the prevalence of gastroesophageal reflux disease (GERD) by mean of GERD-Q questionnaire in patients with upper gastrointestinal tract symptoms in Egypt.
