Filter by:Up to date, devices capable of delivering controlled, calibrated, non-contact cold air stimuli in a MR environment are unavailable for quantitative sensory testing. This project therefore aimed at designing and constructing a novel MR-compatible, computer-controlled cold air stimulation device that produces air puffs in a broad flow and cold temperature range. By means of this device, detailed psychophysically testing and subsequent brain scanning of dentine hypersensitivity (DH) subjects will be possible to gain new insights about DH mechanisms.
Many patients with endometriosis experience extra genital and abdominal symptoms as a major part of their problem. This includes gastrointestinal dysfunction with pain, urinary symptoms compatible with interstitial cystitis and gastrointestinal symptoms resembling the irritable bowel syndrome (IBS). Such problems may be secondary to changes in autonomous neuronal structure and function elicited by the endometriotic elements, which may cause a "visceral syndrome" with the above mentioned symptoms. The investigators hypothesize that dietary treatment will improve the experience of gastrointestinal symptoms, pain and quality of life in patients with endometriosis-related irritable bowel syndrome. The aim of this first randomized, placebo controlled pilot study investigating patients with both endometriosis and IBS, is to test the application of a low FODMAP diet and a placebo diet for endometriosis-related IBS-like symptoms in order to stablish a platform for a randomized controlled study. Thus, the primary aim of this pilot study is to investigate the applicability of a placebo diet in patients with endometriosis and to investigate the compliance in both intervention group and control group. In addition, the aim is to investigate whether the participants find the diet manageable and whether they are able to identify the placebo diet.
This single center study will investigate the efficacy of an experimental stannous fluoride containing dentifrice in relieving DH compared with a standard fluoride dentifrice after short term use.
This single centre study will be used to investigate the efficacy of an experimental stannous fluoride containing dentifrice in relieving dentinal hypersensitivity (DH) after short term use compared with a standard fluoride dentifrice.
The purpose of this study is to determine etokimab safety, tolerability and activity in adult participants with peanut allergy.
This study compares the efficacy of two dental interventions in the treatment of cervical dentine sensitivity. The participants will be selected from adult dental patients registered at a general dental practice in West Sussex, UK. The participants will be split into 2 groups. One group will receive the intervention of topical fluoride varnish application while the other group will receive a topical application of self-etching dentine bonding agent.
This study will investigate the effectiveness of nanohydroxyapatite (nano-HAP)-containing toothpastes and cream to relieve dentin hypersensitivity, comparing it with those of a commercial desensitizing dentifrice containing calcium sodium phosphosilicate (Novamin® technology) and a standard fluoride dentifrice containing 1,500 ppm fluoride as sodium monofluorophosphate (MFP).
The purpose of this study is to investigate the differences in the quality of life of patients and caregivers who are treated by general pediatricians versus pediatric dermatologists for eczema (atopic dermatitis or AD).
This study evaluates the safety of Viaskin Peanut 250 mcg in the treatment of peanut allergy in children from 4 to 11 years of age. Subjects will receive either Viaskin Peanut 250 mcg or a placebo for a period of 6 months, after which all subjects will be receiving the active treatment up to a period of 3 years under active treatment.
Irritable Bowel syndrome (IBS) is a very frequent condition in children. Its management is difficult, often resulting in a persistence of chronical abdominal pain. In adults, many patients affected by IBS improve under a gluten-free diet, even in the absence of Celiac Disease (CD) or wheat allergy. This condition is called Non Coeliac Gluten Sensitivity (NCGS). However, it is still not clear how to diagnose and manage NCGS, and the pathophysiological mechanisms also remain elusive. The aim of this study is to determine if NCGS exists in children with IBS and to identify the clinical, serological, and histological characteristics, which could distinguish patients with NCGS from conventional IBS and CD patients. This is a prospective cohort study in a population of children affected by a moderate to severe IBS for more than 6 months. All children had a Gluten Free Diet (GFD) for 6 weeks. Then, children who improved under GFD were randomized in two groups for a double-blind placebo-controled trial. One group had a reintroduction of gluten followed by a wash-out period, then a placebo reintroduction, whereas the other group had the placebo first, then the wash-out and the gluten reintroduction.
