Active clinical trials for "Dermatitis"

This pilot clinical trial studies KeraStat Skin Therapy in treating radiation dermatitis in patients with newly diagnosed stage 0-IIIA breast cancer. Radiation dermatitis is an itchy, painful skin rash that can occur following treatment with radiation. KeraStat Skin Therapy may be a better treatment for radiation dermatitis.

Atopic dermatitis(AD) is one of manifestation in atopic march. The prevalence of AD is increased. In 1998, the investigators found the prevalence of AD about 15 % in Thailand. AD is diagnosed by clinical as Hanifin and Rajka criteria. There are 3 group of severity defined by SCORAD(Scoring Atopic Dermatitis) : mild (<25), moderate (25-50) and severe (>50). The natural history of AD was mentioned in 3 groups: complete remission, persistent and intermittent. Atopic march is the progression of atopic disease that has atopic dermatitis as the first manifestation then patients will have allergic rhinitis or asthma in the future. The investigators do a retrospective study to understand the natural history of AD as well as it associate with atopic march. That might be a predictive factor of AD and atopic march

A total of 30 subjects with moderate to severe atopic dermatitis. Thirty subjects without AD matched for sex, age and coronary artery disease risk factor with the AD subjects will also be included. All subjects will undergo the following imaging procedures: a 18FDG-PET to quantify vascular inflammation in the ascending aorta and carotids and a MDCT to calculate the Agatston score. Skin and blood biomarkers will also be assessed.

The prevalence of allergic diseases (atopic dermatitis, asthma, rhinitis, conjunctivitis and food allergy) has increased dramatically in industrialized countries over the last 20-30 years. Allergic diseases are present especially in children and young adults, but all age groups are affected, with variations across countries and age. To propose new therapies, the investigators must first understand the physiopathology. Since their discovery the regulatory T cells have continued to be the subject of work to understand their role in maintaining immune homeostasis in the human body but also their involvement in autoimmune diseases, inflammatory diseases, transplants of solid organs or fluids and allergic diseases. It was identified two broad classes of regulatory T cells: T cells = natural regulators acquisition of a phenotype and a regulatory function right out of the thymus ( CD25 + / CD127 + low / FoxP3 +). T cells induced regulators = acquisition of a phenotype and a regulatory function on the periphery depending on the cytokine micro-environment. Phenotypic characterization of these is less obvious and even more so than during the last ten years several induced regulatory T cell populations have been described ( eg, Tr1 ). A new subpopulation of T cells induced in patients with inflammatory bowel disease recently identified have a particular phenotype as bearing the CD4 and CD8 double marking with a regulatory phenotype. These regulatory T cells are also induced a specific of a commensal intestinal bacterium (Faecalibacterium prausnitzii). Regarding allergies, it has been widely demonstrated a relationship between changes of the intestinal microbiota and the occurrence of allergic diseases. The investigators would therefore propose a cross-sectional study, single-center, controlled, single blinded to study the role of T cells called double positive induced regulators DP8 to compare the frequency and the regulatory function of specific DP8 of Faecalibacterium prausnitzii in atopic dermatitis, asthma and allergic rhinitis compared to control samples.

Pilot study of flexible and wearable sensor to monitor nocturnal scratching behavior

This study will evaluate the incidence of allergic manifestations (the first of which is atopic dermatitis) and infectious diseases in children fed with an infant formula under real conditions of use.

This pilot study will evaluate new methods for the collection, storage, shipment, and RNA extraction of skin tape specimens from children with atopic dermatitis (AD) that will facilitate the multi-center SunBeam Birth Cohort study. Additionally, this pilot study will test new methods for the generation of whole transcriptome sequencing data from skin tape RNA and whether these data reflect the transcriptional state of the skin in health and disease.

Sleep sensors, wrist worn accelerometers, polysomnography (PSG), and associated data analysis platforms would provide quantitative and qualitative knowledge regarding the action of scratching and sleep quantity in a symptomatic atopic dermatitis (AD) population. The overall aim of this research is to validate the use of sensor technology and digital measures to quantitatively and qualitatively evaluate scratch and sleep in AD patients, and specifically in this study in children ages 2 to 11 years. To evaluate this experimental paradigm, the investigators propose using wearable accelerometers, a sleep sensor, PSG, videography and associated traditional patient-reported outcome measures/clinical outcome assessments (PRO/COA) in patients/caregivers with AD in a well-controlled in-laboratory and at-home study.

This study observes a liquid skin protectant that is a polymeric-cyanoacrylate solution designed to protect intact or damaged skin due to radiation.

During the COVID-19 pandemic after reopening of the country, school, kindergarten and daycare, children have been obligated to do frequent handwash. The study group wished to investigate whether this has had implications on symptoms of dry, red, itchy or sore hands and hand eczema. The investigation was performed within the first and second week after reopening by questionnaires distributed to parents electronically via schools, kindergartens and daycare facilities electronic platforms.
