Active clinical trials for "Hypersensitivity"

A pilot study to determine the ability of a stannous fluoride containing toothpaste to provide immediate and short term relief from dentine Hypersensitivity compared to a control toothpaste.

Will the use of Bioactive glass with air abrasion technology (Sylc) compared to Fluoride Varnish (Biflourid 10) affects the degree of pain in patients complaining from hypersensitivity due to non-carious lesions?

Purpose: To determine whether implantation of an intraocular lens (IOL) with a modified anterior and posterior aspherical surface (Akreos AO, Bausch & Lomb,Inc) results in reduced ocular aberrations (spherical aberration) and in improved contrast sensitivity after cataract surgery. Study hypothesis: the implantation of an intraocular lens (IOL) with a modified anterior and posterior aspherical surface (Akreos AO, Bausch & Lomb,Inc) results in reduced ocular aberrations (spherical aberration) and improved contrast sensitivity after cataract surgery. Setting: Department of ophthalmology, Hospital das Clínicas, University of São Paulo, São Paulo, Brazil. Overall Study design: This will be an intraindividual randomized double-blinded prospective study. Patients will be randomized to receive an aspheric IOL Akreos AO in one eye (25 eyes; Bausch & Lomb, Inc), and an spheric IOL Akreos Fit (25 eyes; Bausch & Lomb, Inc.) in the fellow eye. Ocular aberrations with a 5.0 mm and 6.0 mm pupil will be measured with a dynamic retinoscopy aberrometer after 1 and 3 months. Uncorrected and best-corrected visual acuity, out-focus performance and contrast sensitivity under mesopic and photopic conditions will be also measured. All patients will be followed for 3 months.

The purpose of the study is to test whether vaccinations with CYT003-QbG10 can improve allergy symptoms in patients with house dust mite allergy. The active treatment will be compared against placebo.

The objective of this study is to characterize the pharmacokinetic (PK) profile of brompheniramine maleate (BROM) in children and adolescents, ages 2 to less than 18 years following dosing in accordance with current weight-age dosing guidelines. Once characterized, the PK data will be pooled with adult PK data from other studies and analyzed under a separate analysis plan to confirm or refine the existing OTC doses in children aged 2 to <12 yrs and adolescents aged 12 to <18 yrs.

The purpose of the study is to compare sensitivity of visceral pain in the esophagus using different pain stimuli.

The aim is to analyse the results of per oral immunotherapy treatment in severe milk, peanut or egg allergy in adults. This is the second part of the oral immunotherapy study in adults at Skin and Allergy Hospital. The diagnosis of food allergy is verified with positive history, skin prick tests, egg and milk allergen specific IgE (immunoglobulin E) antibodies. In addition, food allergy is verified with an open label (milk allergy) or blind (peanut and egg allergy) allergen specific challenge test. OIT (oral immunotherapy) is performed according to a detailed plan. Lung function parameters are followed before OIT and and a year after OIT.

Food allergy is a potentially life-threatening condition, and its prevalence continues to increase despite public health efforts. There are currently no known therapies that can reliably prevent food-induced anaphylaxis. This is an open-label study designed to determine the ability acalabrutinib to prevent signs and symptoms of anaphylaxis during an oral food challenge in food-allergic adults.

This will be a split-plot design, randomized, parallel, double-masked feasibility study to evaluate the role of a test lens on contrast sensitivity with and without glare.

This is a bilateral, non-dispensing, randomized, cross-over, single-masked study. There are a total of 3 visits where all study endpoints will be measured in all subjects at baseline with habitual lenses and under the two testing treatments sequentially in separate visits based on the randomization scheme
