Filter by:The insufflation of air in the viscera is indispensable during endoscopy. However, the distension of the bowel that follows is often the cause of abdominal discomfort. Carbon dioxide (CO2) has been widely used for insufflation in endoscopy. CO2 insufflation is demonstrated in the literature to cause lower abdominal discomfort as it is quickly reabsorbed by the body. Endoscopic ultrasonography (EUS) is a method in which you associate the endoscopic view and the ultrasound vision obtained from the inside of the viscera. The diagnostic accuracy of EUS is undermined by the visual artifacts caused by the presence of air between the probe and the organ to be studied. Although the use of CO2 is already widely applied by many endoscopists, there are no studies to date concerning the use of CO2 during EUS from the point of view of the abdominal discomfort related to the procedure and/or the quality of the images obtained. The main purpose of the study is to assess whether the insufflation of CO2 results in a reduction of discomfort of the patients undergoing EUS. The study design is observational because no randomization or other interventions are planned; participants will be assigned to either air or CO2 insufflation according to the endoscopic room equipment (one room is equipped with CO2 insufflation while another endoscopic room is equipped just with air insufflation) and the results of the two groups will be compared. Among the secondary goals the investigators want to evaluate whether insufflation of CO2 is associated with a reduction in the dose required for patients sedation. Finally, the investigators want to clarify whether the use of CO2 is able to produce less visual artifacts than air and thus improve the quality of EUS images.
The purpose of this study is to further evaluate the immunogenicity and safety of 10μg/0.5ml Recombinant Hepatitis B Vaccines(Saccharomyces Cerevisiae) in the Healthy Neonates.
The purpose of this study is to investigate a novel thermosensitive topical gel formulation for the treatment of inflammatory bowel disease (IBD), specifically ulcerative colitis.
The inhibitory effect of low dose GLP-1 is investigated on prandial motility of the stomach, duodenum and jejunum in vivo in humans. Supplementary in vitro studies on the mechanism of action of the GLP-1 inhibition of motility as carried out on muscle strips from the upper gastrointestinal tract in man.
The main objective of this study is to evaluate the efficacy of STW5 Iberogast, over a 28-day period, for the treatment of constipation in parkinsonian patients suffering from gastrointestinal disorders.
Gastroscopy (OGD) is a useful test for investigating a variety of suspected upper GI disorders. But it is uncomfortable for patients and incurs the risk of intubation and sedation, plus a large proportion of procedures reveal insignificant or no pathology. Capsule endoscopy (CE) is the investigation of choice for diseases of the small bowel. It is safe, non-invasive and well-tolerated. The use of CE is traditionally restricted to the small bowel, although newer capsules to image the oesophagus and colon are currently in use. Previous capsules have failed to adequately image the stomach due to its' large volume and rugal folds. Recently a magnetic capsule and handheld magnet has been developed (Mirocam Navi, Intromedic Ltd, Seoul, Korea) to enable an element of manoeuvrability of the capsule. This is unnecessary in the small bowel where the capsule is propelled along its' tubular structure by peristalsis, but in the capacious stomach this may allow the capsule to be steered to examine all areas of the stomach. We have already conducted two feasibility studies in porcine models with promising results and a trial has already evaluated the equipment to steer the small bowel capsule through the stomach into the duodenum. An ongoing study is comparing the ability of this technique to examine the stomach against conventional OGD, in patients with recurrent iron deficiency anaemia. The next stop would be to compare the two modalities under other different conditions. We wish to undertake a prospective single blind controlled trial comparing magnetically assisted capsule examination to conventional OGD in diagnosing upper gastrointestinal pathology in patients with gastrointestinal bleeding.
Long term prognosis and risk factors in functional gastrointestinal disorder (FGID) is largely unknown. The investigators plan to retrospectively analyse a cohort of children who were referred to the Pediatric Clinic due to abdominal pain with the aims to learn more about symptoms and effects of investigations performed. Furthermore, the investigators plan to contact the cases for a follow up using a validated questionnaire and analyse the long term prognosis and risk factors for prolonged severe symptoms.
Background: Performance of endoscopy in children requires more patience, experience, and expertise than in adults. The anxiety of the children is related to parent's separation, loss of self-control, unknown surroundings and strange people that are taking care of them, and frequently unpleasant or even painful procedures. Painful and frightening procedures in children have been shown to result in short-term physiologic changes and long-term behavioral changes. The response to unpleasant stimuli with stress and fear may be exaggerated in children and experienced as pain. Most infants and children and many teenagers need deep sedation or light general anesthesia to complete a successful and safe procedure. Induction of general anesthesia is a stressful procedure itself. Strategies to reduce preanesthesia anxiety include pharmacologic and non-pharmacologic interventions. However, this evidence is based mainly on self reports rather than objective measurements. Therefore, objective and non-invasive measurements to be utilized in the current study, should provide an assessment tools regardless the children's age. Multiple studies, beginning in the 1970's, have shown that humor has many positive effects on physical and mental health and well-being. Previous investigations have reported that humor has beneficial effects on the immune system, stress related to potentially fatal illnesses, pain tolerance, and mental functions. Dream doctors (DDs) are professional medical clowns or stage artists, who received training specifically to understand medical patient's need and to give the patient adjuvant therapy during hospital admissions or ambulatory treatment.The Israel dream doctors project, integrates professional medical clowning into the medical services provided at Israeli hospitals.Studies already proved that presence of medical clowns significantly reduces the level of anxiety during induction of anesthesia in children. Hypothesis of the study: 1) DDs lessen the level of anxiety and attention impairment in children undergoing gastroscopies. 2) DDs improve the satisfaction of children and their parents during gastroscopies. The aim of this study is: 1) To explore the influence of DDs on the satisfaction of children and their parents undergoing gastroscopy, utilizing questioners. 2) To explore the effects of DDs on anxiety and attention of children and their parents, undergoing gastroscopies by means of GSR, startle response and pre-pulse inhibition (PPI) tests, as well as , and measuring anxiety-related biologic indices.
The study was quasi-experimental including patients in two intervention and control groups. Three measurements were done: pretest, post-test, and a two-months follow-up. The study population included patients with irritable bowel syndrome(diagnosed by specialists and based on the criteria of Rome III), who referred to a general Hospital. Fifty two irritable bowel syndrome patients were selected and assigned to two experiment (26 cases) and control (26 cases) groups. The criteria below were considered in selection of patients. Inclusion criteria: 1) Patients should not have participated in other psychological interventions concurrently; 2) Participants had not reported diagnosis of non-functional gastrointestinal illnesses. 3) Women patients had not been in pregnancy; 4) Participants had not met diagnosis of schizophrenia and bipolar disorders. Exclusion criteria: Three or more absences in the group sessions Co-variate variables: 1) demo-graphical variables (age, birth order, and education); 2) clinical variables (global psychological status, mind-body attribution, and duration of disease).
