Active clinical trials for "Hypersensitivity"

Purpose: This study will determine the effectiveness of the use of desensitivity gels prior in office bleaching on risk and intensity of tooth sensitivity caused by in-office bleaching using 35% hydrogen peroxide. Materials and Methods: Fifty patients will be selected for this triple-blind, randomized, cross-over, placebo-controlled clinical trial. 10 minutes prior to bleaching procedure, patients will receive the potassium oxalate 5% desensitivity gel and placebo application on vestibular surface. The whitening treatment with 35% hydrogen peroxide will be carried out in two sessions with a 7-day interval. Tooth sensitivity will be assessed before, during and 24 hours after the procedure using analog visual and verbal scales. Color alteration will be assessed by a Classical guide scale. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by McNemar's test. Data on the sensitivity level for both scales and color shade will be subjected to the Friedman, Wilcoxon and Mann-Whitney tests, respectively (α = 0.05)

The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Banaba has shown evidence that has on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis was that the the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.

The purpose of the study is to assess the efficacy and safety of BAY1841788 (darolutamide (ODM-201)) in combination with standard androgen deprivation therapy (ADT) and docetaxel in patients with metastatic hormone sensitive prostate cancer.

This is a single blind randomised controlled clinical trial in uncontrolled type 2 Diabetes mellitus patients on oral glucose lowering agents, and naive to incretinomimetic. Participants will be randomised in two Arms : arm 1 receiving Liraglutide at 1,2 mg/day and arm 2 Vildagliptine at 100mg/day over 14 days. The two arms will be compared for 14-day changes in insulin secretion and insulin sensitivity.

Increasing drug resistance presents a significant challenge to the efficacies of common empiric eradication regimens for Helicobacter pylori treatment in the mainland of China. Tailored therapy may be the best choice to achieve good efficacy, especially in patients with penicillin allergy. Few studies had evaluated the patients with penicillin allergy.This study is designed to evaluate the efficacy and safety of antibiotic sensitivity-based tailored therapy for Helicobacter pylori treatment in the patients with penicillin allergy.

Currently it is estimated that at least 25 million people in the United States are labeled as penicillin allergic although less than 1.5 million of these are truly allergic. Although combined skin testing and oral challenge is an evidence-based de-labeling strategy the high burden of penicillin allergy labels means these services are available only through specialty allergy practices. There is therefore a need to provide evidence for alternative penicillin de-labeling strategies such as direct oral challenge. Previous studies have utilized quasi-experimental designs. Test dose challenges are currently recommended as a strategy for removal of low risk drug allergies, but the current experience is limited to single arm observational studies and evidence-based strategies for identifying low risk patients are lacking. The investigators objective is to demonstrate the benefit of providing risk stratification in removing penicillin allergy labels for low risk penicillin allergy patients in a single arm intervention pilot trial in the ICU setting, which will pave the way for a future stepped wedge randomized control trial (stepped wedge trial entered separately in clinical trials.gov as NCT03702270)

The purpose of this study is to investigate a modified behavioral treatment for chronic cough due to cough hypersensitivity syndrome (CHS). This type of CC is a non-productive cough that is due, in part, to over-expression of transient receptor potential vanilliod (TRPV) receptors in the airway epithelium, which contribute to a dry cough elicited by typically non-tussive stimuli (e.g., cold air, smells) or by low doses of tussive stimuli (e.g., smoke). Currently available treatment options are limited to neuromodulator medications (e.g., gabapentin, amytriptiline) and behavioral cough suppression therapy (BCST), neither of which is 100% effective. The primary component of BCST is teaching patients to suppress their cough in the presence of an urge-to-cough. Studies have confirmed a reduction in cough sensitivity (as tested with inhaled capsaicin) following 1-4 weeks of successful cough suppression. However, patients with severe CHS are not able to suppress their cough in the presence of uncontrollable environmental stimuli and, hence, do not respond well to the therapy. The purpose of this study is to determine the potential of treating CHS by implementing BCST while stimulating cough with progressive concentrations of inhaled diluted aerosolized capsaicin. The investigators hypothesize this treatment will result in a reduction in cough-reflex sensitivity, cough-related quality of life, and cough frequency.

Background: Nickel is a silvery metal widely used in nature and contained in many foods. Exposure to nickel is responsible for two different types of adverse reactions: Allergic Contact Dermatitis (DAC) and Systemic Nickel Allergy Syndrome (SNAS). The latter is characterized by the presence of extra-cutaneous manifestations, in addition to the skin lesions of the DAC, related to the introduction of nickel-containing foods. Therefore, a nutritional intervention is essential to reduce the symptoms of SNAS. Currently in the literature there are no nutritional guidelines on the treatment and management of patients suffering from SNAS and often the indications provided to patients involve the exclusion of groups of foods for prolonged periods, with the consequent risk of developing nutritional deficiencies and malnutrition. Objectives: to evaluate the efficacy of dietary indications, developed on the most recent scientific evidence, useful for the management of the symptoms associated with adverse reactions to Nickel. Provide practical indications to specialist staff in multidisciplinary patient management and make the patient aware of his problem and help him understand how to manage it independently. Target population: subjects over the age of 18, female, belonging to the U.O. Occupational Medicine Allergology Section at ICS Maugeri of Pavia, with previous diagnosis of Nickel allergy (patch test) and with the presence of gastrointestinal symptoms related to allergy.

Hematological malignancies gather several various pathologies included myeloproliferative disorders (as acute myeloid leukemia (AML) or chronic myeloid leukemia (CML)) and lymphoproliferative disorders (as chronic lymphoid leukemia (CLL), non-Hodgkin lymphoma (NHL) and multiple myeloma (MM)) . Over the last decade, the treatments have evolved significantly but the overall survival remains limited, especially for the AML and MM patients. There's an ongoing imperative to continue in-vitro and in-vivo studies to better evaluate the anti-cancer drugs sensitivity and therefore improving the response to treatments and open new fields of application. The healthy control group will be contributing to produce some pertinent and significant data for the results of the index cases group. The investigators aim to analyze 10 differents drugs, common use in chemotherapy or immunotherapy and evaluate by 2 ways the sensitivity: first, Flow cytometry (cells apoptosis by Annexine V and propidium iodide) on fresh samples and in a second time, monitoring of the blasts in the mouse's blood after injection.

The purpose of this study is to support long-term dentinal hypersensitivity (DH) relief claims of 0.454 percent (%) stannous fluoride (SnF2) containing toothpastes in China.
