Active clinical trials for "Hypersensitivity"

Our study evaluated and compared the postoperative sensitivity of the placement technique (incremental and bulk fill) in class II posterior composite resin restorations bonded with two different adhesive strategies (self-etch and etch-and-rinse).Sixty patients were randomly selected, their age range from 25 to 40 years old. They were divided into 2 main groups according to the packing technique of composite material; incremental Tetric Evoceram and Tetric Evoceram bulk fill composite.30 patients (n=30) were selected for incremental Tetric Evoceram composite restorations and they were equally divided according to the adhesive systems used (etch and rinse or self-etch adhesive strategy) (n=15 teeth).30 patients (n=30) were selected for Tetric Evoceram bulk fill composite restorations and they were equally divided according to the adhesive systems used (etch and rinse or self-etch adhesive strategy) (n=15 teeth).Post-operative pain assessed at 24 hours, 1 week and 1 month using the visual Analog Scale Score (VAS).Each patient was instructed to place a vertical mark on the VAS line at home to indicate the intensity of pain at each assessment period.

To compare visual outcomes for various distances, reading speed, contrast sensitivity, glare occurence, defocus curve and subjective satisfaction in patients implanted with the extended depth of focus lens (Tecnis Eyhance) in one eye and monocal aspheric lens (Tecnis ZCB00) in second eye. Patients undergo visit in 3,6 and 12 months after the surgery.

Pain is the leading cause of disability worldwide. However, the pain sensitivity of individuals varies to a large extent, which often results in the mismatch between clinical diagnosis or treatment and individual's actual needs. There are still no established objective indicators for comparisons between individuals. This integrated pilot project is the first large-scale, multi-modal brain decoding study for pain sensitivity. We will explore the brain network signature of pain sensitivity by analyzing electroencephalogram (EEG) signals and magnetic resonance imaging (MRI.) Meanwhile, we will integrate the innate, environmental, and humanity factors with aforementioned brain network signatures to establish multi- modal objective model of pain sensitivity using machine learning. This research team is composed of more than 30 physicians, scientists, and IT experts, along with international collaborators with expertise in the fields of neuroscience, medical imaging, and human philosophy. The five elite groups constitute this international research team and establish five multi-disciplinary sub-projects: Sub-project A： Pain sensitivity and associated innate and environmental factors Sub-project B： Electrophysiological brain signatures of pain sensitivity Sub-project C： MRI brain signatures of pain sensitivity Sub-project D： Innovative brain computer interface (BCI) technology in pain sensitivity measurement and prediction Sub-project E： Pain and Art: neuro-mental mechanisms and potential applications There are three key features of this integrated project: scientific novelty, technology and humanity. In terms of scientific novelty, in addition to machine learning and big data applications, we will focus on the deep brain structure such as brainstem, in which the image acquisition has been difficult in the past. We will develop an MRI sequence and EEG protocol optimized for brainstem. In terms of technology, we will develop a wearable EEG cap implanted with algorithm chip for clinical measurement to decode the pain sensitivity real time. In terms of humanity, we will combine music and painting appreciation to explore their impact on brain signatures related to pain sensitivity. Furthermore, we will develop potential applications of art intervention in pain modulation. We expect this pilot project to achieve the four following goals: To establish a Taiwan database of pain sensitivity. Meanwhile, to clarify the interactions between the innate and environmental factors of the individual and the brain network, and to identify brain signatures related to pain sensitivity. (sub- projects A, B, C) To confirm the brain signatures for predicting the pain sensitivity using machine learning. In addition, to develop wearable devices such as EEG cap for large sample screening by combining the brain-computer interface through the industry-university cooperation (sub-projects B, C, D) To explore the plasticity of brain signatures related to pain sensitivity by sensory modulation such as music, painting appreciation or transcutaneous electrical nerve stimulation, and to explore the application potential for pain modulation (sub-projects B, C, D, E) Based on the cooperation model of this international research team, we will cultivate young researchers, and promote academic interactions among different team members, and improve the international visibility and competitiveness of Taiwan (sub-projects A, B, C, D, E)

Type of study: Randomized Clinical trial To compare post-restorative sensitivity between titania nanoparticle reinforced bonding agent and bonding agent without nanoparticles in posterior composite restorations. Participants aged 18 years and above with Class-I and Class-II Carious lesions are allocated in two groups. Group A will undergo composite restoration with Nanoparticles incorporated in bonding agent. Group B will undergo restoration without nanoparticles in bonding agent.

The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.

Subjects will be enrolled into 3 balanced groups each using a different strength toothpaste. Dental hypersensitivity (DHS) will be assessed at study start, midway and study end.

This study investigates whether 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. Potential variations in allergic symptoms during season will be compared with spread of MB spores. Sensitation to MB and MB allergy are to be tested with skin prick test (SPT), measurements of spesific immunglobulin E (IgE) in serum, passive basophil activation test (pBAT) and nasal provocation test (NPT)

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?

The goal of this study is to identify changes in cells that are related to the treatment with Cat-PAD (ToleroMune Cat).

The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.
