Active clinical trials for "Hypersensitivity"

Obstructive sleep apnea (OSA) and hypothyroidism are both commonly found in clinical practice, and share a number of symptoms and clinical features. It has been shown that hypothyroid subjects are at high risk of developing sleep disorder breathing and OSA, and adequate thyroxine treatment may reduce the sleep disordered breathing.. However, the time-course and effect of treating subclinical hypothyroidism in OSA patients on the respiratory events during sleep is not known. Subclinical hypothyroidism is associated with an increased risk of coronary heart disease (CHD). Dyslipidemia is a known complications of subclinical hypothyroidism and the effect of thyroxine treatment on lipid profile is controversial . Some reports suggested higher serum high-sensitivity C-reactive protein (hs-CRP), than healthy subjects; however, the effect of levothyroxine is controversial. This project will help us to know if the treatment of subclinical hypothyroidism will improve the symptoms and reduce the progression of OSA, which may improve patients' quality of life by reducing the complication of OSA (hypertension, , depression, Cardiovascular diseases, etc.) or may even reduce mortality.It will help us to know the effect of subclinical hypothyroidism treatment on of lipid profiles and hs-CRP.

The aim of this study is to further characterize the treatment related changes in insulin sensitivity, substrate metabolism and intra hepatic- and intramyocellular lipid content in patients with hypothyroidism

The aim of this study was to evaluate the efficacy of low energy laser for the treatment of dentinal hypersensitivity due to periodontal therapy.

The study determines how a 6 months oral immunotherapy (OIT) program with hen's egg (HE) effects cellular and humoral immune responses in 50 children with HE allergy. Clinical data, transcriptomics and epigenetics are combined and analyzed by advanced system biology methods. This study will provide better understanding of the effects and mechanisms of OIT.

To evaluate the photo-protector effect of BC_3 (E212657) formulated in SPF compared to SPF alone on long-UVA induced pigmentation in healthy volunteers.

Although the superiority of ultrasound guidance over neurostimulation (NS) has been demonstrated, it has its limits, namely when used for a deeper block (device limits) or if used by a less experienced operator (ability to recognize structures, to correctly position the needle). In addition, its use has failed to consistently prevent intra-neural injection. The question of the usefulness of NS in addition to ultrasound is therefore still relevant. A great geographical disparity exists in the habits of nerve localization. The reluctance to use NS stems mainly from doubts about its effectiveness. The threshold used to consider that the needle is sufficiently close to the nerve and the one used to exclude an intraneural injection have been disputed in several studies. Another weakness of studies concerning NS since the advent of ultrasound guidance is the impossibility of generalizing the results. All clinical studies were performed in an academic setting, and a large majority of them specify that the blocks were performed by - or supervised by - regional anesthesia experts. The only study that attempted to determine the sensitivity of NS used ultrasound as a gold standard. The choice of the ultrasound position as the gold standard is debatable, since it is dependent of the operator. The clinical success of nerve blocks would be a better standard. No study to date has made it possible to calculate the specificity and sensitivity of NS in addition to ultrasound guidance, and therefore, to obtain the positive and negative predictive values of the technique. Obtaining these values could allow each clinical setting or individual to determine the contribution of NS to their rate of success, as a modest increase in the success rate or a minimal decrease in the risk of neuropathy would be clinically significant. The hypothesis is that the sensitivity and specificity of NS justifies its use in combination with ultrasound guidance in most settings, but that the gain in efficiency varies depending on the context (for example depending on the local success rate). To determine the required sample size to test this hypothesis and plan for a definitive study on the question, the investigators need to know what is the local failure rate (incidence of studied event) and what could be the possible rate of patient enrollment. This preliminary, feasibility study will aim to confirm that the local failure rate is compatible with the 5% rate observed in the literature.

2 different varnishes will be used to test their effectiveness in controlling teeth hypersensitivity in adult patient.

The present project will compare the effect of DH reduction using three different dentifrices (Sensodyne Repair and Protect - NOVAMIN technology; Dentalclean Daily Regenerator - REFIX technology; Dentalclean Daily Regenerator - REFIX technology + potassium citrate) in periodontal patients. The evaluation will be in 6 moments: T1 and T2- immediately before and after scaling and root planing (SRP) procedures; T3-after polishing sensitive areas with rubbers cups and the dentifrice determined for each group of patients and T4, 5, 6- After 2, 4 and 8 weeks of SRP. Profissional assessments and patient perception data will be performed.

The Aim of This Work is to Compare the Effect of Oral Methyl Prednisolone on Different Radiological Patterns of Hypersensitivity Pneumonitis and to Evaluate the Patient's Clinical and Functional Status After Taking the Required Dose of Methyl Prednisolone. Not All Hypersensitivity Pneumonitis Patients get the Same Therapeutic Effect after taking Corticosteroid so by Comparing the Effect of Methyl Prednisolone on Patients With Different Radiological Pattern we Will be Able to Select the Patient Who Really Need to Take Corticosteroid and Who Don't so we Will Protect the Patient Who Doesn't Need to Take Oral Corticosteroids From Its Numerous Side Effects All Patients Will Undergo the Following Assessment Before and After Taking 0.5 mg/kg/Day of Methyl Prednisolone for 8 Weeks : High Resolution CT (HRCT) of Chest , Chest X-ray , Spirometry, 6 Minute Walk Test to Evaluate the Patient's Functional Status and Oximetry to Measure Percentage of Oxygen in Blood

This study aims to evaluate the longevity and efficacy of two products potassium oxalate-basedin two concentrations, 10% and 5%, by triple randomized blind clinical trial (split-mouth) . The desensitization approach (single agent) and the long-term effectiveness (baseline, 1 week, 2 weeks, 3 weeks). Data will be collected, tabulated and submitted to statistical analysis.
