NCT ID: NCT04351412 Completed - Dentin Sensitivity Clinical Trials

Comparison of Dentin Hypersensitivity Reduction Over a 1-month Period

Start date: January 10, 2020
Phase: N/A
Study type: Interventional

Here we assessed the clinical effectiveness of Gluma, fluoride varnish, and the Tetric N-Bond one-step self-etch system in alleviating DH instantly and over 1 month, after a single topical application.A randomized, double-blind, clinical trial was conducted on 55 patients (25 males, 30 females; age: 20-49 years). Seventy teeth were randomly assigned to three groups: Gluma (n = 24); fluoride varnish (n = 23); and Tetric N-Bond adhesive (n = 23). Sensitivity to tactile, air blast, and cold stimuli were investigated.. A visual analogue scale was used to assess tactile stimuli, and the Schiff Cold Scale to assess air blast and cold stimuli. DH was evaluated immediately post-treatment, and at the 2-week and 1-month follow-up. Between-group and within-group comparisons were made.

NCT ID: NCT04340869 Recruiting - Dentin Sensitivity Clinical Trials

Treatment of Dentin Hypersensitivity Using Different Desensitizing Agents

Start date: August 1, 2019
Phase: N/A
Study type: Interventional

Treatment of Dentin Hypersensitivity Using Theobromine , Remin Pro , and Combination of Both Materials

NCT ID: NCT04330118 Recruiting - Clinical trials for Drug Hypersensitivity

Origin and Function of Eosinophilic Polynuclear During DRESS Syndrome

DRESSEO
Start date: July 15, 2020
Phase:
Study type: Observational

Drug Hypersensitivity Syndrome or DRESS for "Drug Reaction with Eosinophilia and Systemic Symptoms" is a serious drug allergy which can be life-threatening for patients with serious organ damage. The pathophysiology of DRESS is still not fully understood. In particular, no study has focused on the characterization of eosinophils, while paradoxically eosinophilia is one of the diagnostic criteria. Likewise, there is no data about the origin of eosinophils and few data are available concerning immune polarization of T-cells or the involvement of innate lymphoid cells type 2 in the recruitment of eosinophils. Our preliminary data on increase activation markers membrane expression of cutaneous eosinophils suggest that this approach could allow the identification of endotypes in which eosinophils are involved and contribute to organ damages. The correlation between tissue infiltration of eosinophils and their degree of activation would then justify the development of targeted therapeutic strategies in DRESS syndrome (anti-IL-5 therapy?). The aim of the project is: 1) Evaluate the activation status of circulating and cutaneous eosinophils in patients with DRESS compared with drug induced maculopapular exanthema without or with eosinophilia (but do not fulfill DRESS criteria) and healthy subjects; 2) Understand the pathophysiological mechanisms at the origin of this eosinophilia.

NCT ID: NCT04330092 Completed - Cow's Milk Allergy Clinical Trials

Diagnosis of Cow's Milk Protein Allergy

Start date: May 1, 2020
Phase:
Study type: Observational

The study will assess the diagnosis of cow's milk protein allergy (CMPA) among infant and children in assiut university children hospital using skin prick test and specific serum IgE as well as their management.

NCT ID: NCT04329078 Not yet recruiting - Allergy;Food Clinical Trials

Relevance of Sensitization to Legumes in Children Allergic to Peanut

Start date: April 1, 2020
Phase:
Study type: Observational

The objectives of this study are to determine in children allergic to peanut (i) the prevalence of sensitization to other legumes, (ii) the prevalence of allergy to each legume in patients who are sensitized to it (iii ) the severity of the allergy to legumes other than peanut

NCT ID: NCT04327297 Not yet recruiting - Cow Milk Allergy Clinical Trials

Mineral Status Ininfants With Cow's Milk Protein Allergy

Start date: October 1, 2020
Phase:
Study type: Observational

This study evaluate the mineral status of infants with cow's milk protein allergy which is affected due to the elimination of milk , and the change in this mineral status after receiving amino acid - based formula for 12 weeks.

NCT ID: NCT04322838 Recruiting - Allergy Clinical Trials

Tromsø Birch Rust Allergy Study. Allergy to Birch Rust, a Possible Explanation to Seasonal Airway Allergy During Autumn?

Tro-BRA
Start date: August 1, 2020
Phase:
Study type: Observational

In this project we study if spores from birch rust fungi (Melampsoridium Betulinum = MB) may be the eliciting allergen in patients with seasonal airway allergy during autumn in North Norway. Patients with suspected allergy to MB are compared with non-allergic controls using data about allergic disease and daily allergic symptoms during autumn. Daily spread of MB spores are compared with daily variations in allergic symptoms. Sensitization to MB and MB allergy are tested with skin prick test, specific immunoglobulin E (IgE) in serum, nasal provocation test and basophil activation test (BAT).

NCT ID: NCT04318483 Completed - Milk Allergy Clinical Trials

Characteristic and Evolution of an Atypical IgE-mediated Cow Milk Allergy Form With Hands and Feet Angio-oedema

IgE-CMA
Start date: May 4, 2020
Phase:
Study type: Observational

Cow milk allergy is one of the most frequent food allergy among children. Cow milk protein's avoidance is needed until spontaneous recovery during the two first years of life. A atypical clinical form with angio-oedema of hands and feet which is associated with high rate of lactoserum's IgE might be a hope of an earlier recovery.

NCT ID: NCT04315545 Recruiting - Clinical trials for Diabetes Mellitus, Type 2

Pregnancy Outcomes and Maternal Insulin Sensitivity

PROMIS
Start date: February 6, 2020
Phase:
Study type: Observational [Patient Registry]

The PROMIS study will focus on maternal insulin sensitivity thourghout pregnancy and postpartum in a moderate to high risk population (BMI ≥25 kg/m2) in developing adverse pregnancy outcomes. Next to the OGTT, the meal tolerance test (MTT) will be used as a tool for metabolic testing. The investigators hypothesize that (early) pregnancy assessment of maternal glucose-insulin metabolism with a MTT in a moderate to high risk group identify more mothers at risk for adverse pregnancy outcomes compared with standard OGTT testing at 24-28 weeks.

NCT ID: NCT04312438 Recruiting - Food Allergy Clinical Trials

Safety of Oral Food Challenge With Cow's Milk Proteins in Children With Food Allergy

Start date: June 2020
Phase: N/A
Study type: Interventional

The aim of the study is to assess the safety of an oral food challenge (OFC) with cow's milk proteins and to assess the tolerance of cow's milk proteins in children with a food allergy after introducing cow's milk into the diet.
