Filter by:A randomized, controlled, double blind exploratory study to explore the effects of two different potassium nitrate concentrations and water on exposed dentine in reducing dentinal hypersensitivity. Solutions will be applied for either 2, 5 or 10 minutes and assessed by visual analogue scale (VAS) scores following evaporative (air) stimulus.
The investigators aim to asses the effect of dieto-therapy and of nutritional counseling on the nutritional status, body growth and tolerance acquisition in children with cow's milk allergy.
- Hypothesis 1: Food allergies are associated with poor growth which can be corrected with nutrition intervention. - More than 10% of children with multiple food allergies will have a weight-for-age z-score less than - 2 at diagnosis. The z-score is a measure of the distance from the mean value, or 50th percentile on the growth chart. A z-score of less than - 2 indicates that the child is underweight. - Growth parameters of children with multiple food allergies will improve after intervention by a team that includes a dietitian and an allergist. - Hypothesis 2: Food allergies are associated with low micronutrient intake which can be corrected with nutrition intervention. o More than 30% of children with multiple food allergies will consume less than 67% of the Dietary Reference Intake for at least one macronutrient or micronutrient at diagnosis. - Macronutrient and micronutrient intake will increase after intervention by a team that includes a dietitian and an allergist. • Hypothesis 3: Food allergies are related to behavioral feeding problems which can be corrected with nutrition intervention. - At least 25% of children with multiple food allergies will have behavioral feeding problems at diagnosis. - Prevalence of behavioral feeding problems will decrease after nutrition intervention.
The primary objective of this clinical trial is to determine whether a new amino acid-based formula is hypoallergenic as defined by the American Academy of Pediatrics (2000), demonstrating that the test formula does not provoke allergenic activity in 90% of infants or children with confirmed cow's milk allergy (CMA) with 95% confidence as compared to a commercially available hypoallergenic formula.
Seasonal allergic conjunctivitis (SAC) is an irritating eye condition that affects many people, caused by hypersensitivity to normally harmless substances such as pollen, and often accompanies seasonal hay fever. Treatments that can be used before initiating medical therapy include artificial tear supplements (ATS) and cold compresses (CC). However, there is no evidence in the scientific literature that demonstrates their efficacy compared to no treatment or their combined effect with anti-allergic medication. Therefore the investigators aim to examine the efficacy of ATS and CC alone, in comparison to anti-allergic medication, and CC in combination with anti-allergic medication. In addition, the investigators also aim to determine the time course of ocular allergic reactions. At the end of the study the investigators will be able to see whether or not ATS and CC are effective in treating SAC.
The purpose of this study is to determine if walnut oral immunotherapy can be used in participants allergic to tree nuts to reduce tree nut allergy and induce changes in the participant's immune system.
The study will evaluate the efficacy and safety of BM32 in grass pollen allergic subjects. It will test the hypothesis that either of two doses of BM32 will lead to a sustained relief off allergy symptoms over a two year study period.
The common cold is a major cause of nasal obstruction and reaches children and adults two or more times a year. At the moment, there is no cure for the common cold, and therefore the reduction of symptoms is the focus of the treatment. The study has parallel distribution design, with two equal groups, in which one group will be treated by a combination of naphazoline hydrocloride + pheniramine maleate + panthenol and the other will receive treatment with naphazoline hydrocloride.
This is a study for children and adults who are interested in a new therapy for their allergies to dust mite and timothy grass. The new therapy is called sublingual immunotherapy and the investigators are testing if it is safe and well tolerated.
The purpose of this study is to evaluate the non-inferiority clinical efficacy of two different drug associations in the treatment of acute cutaneous rash in children between 2 and 12 years old.
