Filter by:The main objective of the study is to observe changes in the subjects' sleep quality, skin condition and life status after 4 weeks of using a sleep aid drink (AOXMED Poria γ-aminobutyric acid drink). This is a single-center, randomized, double-blind, controlled, 4-week (28-day) clinical study conducted in Chinese healthy women aged 25-55 years old who were offered a sleep aid drink.
Pemphigus diseases are life-threatening chronic autoimmune blistering diseases characterized by split formation within the epidermis and surface-close epithelia accompanied by acantholysis. Autoantibodies (Abs) are mainly directed against two structural proteins of the epidermal/epithelial desmosome, desmoglein (Dsg) 1 and Dsg3. Two main pemphigus variants can be differentiated, pemphigus vulgaris (PV), and pemphigus foliaceus (PF). Diagnosis of PV and PF is based on the combination of the clinical picture, histological picture of acantholysis, direct immunofluorescence microscopy (DIF) of a perilesional biopsy and serology. The present "Ritux 4" trial is the fourth academic study with the French study group on auto immune bullous skin diseases (Groupe Bulle) to assess the use of rituximab in auto immune bullous skin diseases, in particular pemphigus. The 3 previous trials have been published in outstanding Journals (N Engl J Med 2007, Science Transl Med 2013, The Lancet 2017 and 2020), and have led to the approval of rituximab in pemphigus by the FDA in 2018 and EMA in 2019. In addition, an industry-sponsored trial testing rituximab versus mycophenolate mofetil in pemphigus, that the investigators have largely contributed to design has been very recently accepted for publication in the N Engl J Med (2021). The investigator hypothesize that a maintenance therapy using an infusion of 1g of rituximab at Month 6 in patients whose anti-Dsg Abs have not sufficiently decreased at Month 3 after the initial cycle of rituximab (persistence of anti-Dsg1 Abs> 20 UI/ml and/or anti-Dsg3 Abs> 130 UI/ml), and or had an initial PDAI score >45 ( first year of follow-up), and the re-treatment with 1g of rituximab of patients whose anti Dsg Abs re-increase during the evolution of pemphigus after the initial cycle of rituximab (anti-Dsg1 Abs> 20 IU/ml, anti-Dsg3 Abs> 50 UI/ml), could be effective in preventing the occurrence of relapses, thus avoiding to restart a CS treatment, and would provide benefit as compared with the current treatment strategy of retreating patients with 2 g of rituximab (1g at Day0 and Day14) combined with oral CS patients, once a clinical relapse occurs.
Vulvar disease in Nigeria A look at awareness within patients and health practitioners, self-reported and actual prevalence within communities in Nigeria
This study is a double-blind placebo controlled study to assess whether oral astaxanthin can improve skin hydration, skin elasticity, improve skin pigmentation, and reduce facial redness.
Athletes commonly face skin injuries during training and competition, which can negatively impact their performance and physical health. Injuries such as abrasions, cuts, burns, and sunburns can limit muscle contractions and range of motion, cause discomfort, and lead to bacterial infections. In addition, skin damage can lead to long-term skin problems such as skin aging and cancer, affecting athletes' overall health and performance. Protecting the skin is crucial for athletes to maintain optimal performance and physical health. The use of steroids is limited for athletes due to their status as banned substances. Topical steroids may also cause negative side effects, making it necessary to find alternative skin care options for athletes such as tug-of-war athletes. This study aims to evaluate the effectiveness of a topical hydrating cream for skin care in this population. The study involved using a moisturizing cream on the more severely affected side of one hand while the other hand acted as a comparative control group. After two weeks, the sides were switched, and the study continued for four weeks in total.
The goal of this clinical trial is to learn about the effects of "red flavonoid" substance on skin, which is extracted from a plant called Camellia japonica, in adults aged of 45 or older with photo-damaged skin. The main questions it aims to answer are: - Does red flavonoid have an anti-aging effect? - Does red flavonoid have any skin quality-improving effects? Participants will - Be using creams with or without red flavonoid (only moisturizing creams) and sun-screen for the duration of the study. - Get a skin biopsy before and after using the creams. - Be taken photos of the face and neck region and have a skin examination at each visit. - Complete a self-questionnaire at final visit. Researchers will compare the group who uses red flavonoid facial cream with the group who uses moisturizing cream to see if red flavonoid has an effect on appearance and structure.
The primary objective of this pilot study is exploratory investigation evaluating the Potenza microneedle fractional radiofrequency (RF) device and may be used in combination with the Icon intense pulsed light (IPL) device.
The aim of this study is to evaluate persons/patients with different skin diseases or pain to evaluate whether unhealthy perfectionism, stress, anxiety, impostor phenomenon (inability to realistically assess your competence and skills) and lack of self-compassion (a positive attitude towards ourselves), have impact on symptoms, handling, and treatment regarding some dermatological diseases/pain.
To assess VeCollal formula on skin condition improvement
Medical condition and pathology studied skin pigmentation. Justification / rationale for the study UV are both the physiological stimulus for skin pigmentation and the main etiological factor in melanoma. Recently, visible (blue) light has also been described to induce skin pigmentation, without any obvious pro-carcinogenic effect. Studies have been carried out to identify genes induced by UV in melanocytes and to understand the mechanisms responsible for photo-induced skin pigmentation. However, the rarity of these cells in the epidermis (3% of cells) has so far been an insurmountable obstacle to achieving this goal. The same is true for visible light, for which the data is even more patchy. The advent of transcriptome analysis techniques at the single cell or single nucleus level will allow us to overcome this obstacle and identify the transcriptional effects of UV and blue light in melanocytes in-situ, as well as in other skin cells (keratinocytes, fibroblasts). Understanding the molecular mechanisms regulated by UV and blue light in melanocytes and other cells will reveal new key steps in skin pigmentation. The data from our study will be used to develop new photoprotective agents as well as new treatments for pigmentary pathologies. Primary objective Describe the variations in gene expression induced by solar ultraviolet (UV) radiation or blue light in human melanocytes in vivo. Secondary objectives Describe the variations in gene expression induced by ultraviolet (UV) radiation sunlight or blue light in other skin cells. Evaluation criteria Single cell transcriptome analysis Immunolabelling on skin sections Population and number of inclusions Healthy male volunteers, phototype III on the Fitzpatrick scale, age 25 + 5 years and of similar corpulence (body mass index between 20 and 28). 2 inclusions Duration of the study Total duration of the study: 12 months Duration of the inclusion phase: 1 month Duration of participation for a patient: 11 days Methodology Two healthy volunteers will be exposed to UV or visible light in the forearm region. Suction blisters, and skin biopsies will be performed in the test areas, suction bubbles for transcriptome, biopsies for immunohistochemistry. The study of gene expression in the different cell types will be done by RNA-Seq on single cells, using the 10X genomics approach. Finally a validation of the results will be carried out by immunostaining with specific antibodies or RNA-Scope. Course of the study - Day 1: The study begins with the determination of the Minimum Erythemal Dose (MED) for each subject in the region of the forearms. This determination will be carried out by means of the administration of six different doses in increasing stages of 25% of UVB + UVA rays (simulated solar ultraviolet spectrum) on six selected test areas (each 1.3 cm²). Exposed areas will be assessed 24 + 2 hours after exposure on Day 2, erythema will be assessed Day 2: Reading of the DEM, and irradiations on two zones in the region of the forearms with respectively a dose of 2 DEM UV, and 48J/cm2 in visible light. A third non-irradiated area will serve as a control. Day 3: A skin blister and biopsy will be performed on each of the three test areas. Cells collected in the blister fluid will be used for the transcriptome and biopsies for validation by immunohistochemistry. Day 11: The subjects will be seen again eight days after the day of sampling, i.e. on Day 11 for removal of sutures and monitoring of healing. On the same day, an evaluation of the level of UV pigmentation induced on each test area will be carried out visually and by colorimetry.
