Observational Study of the Genetic Architecture of Neutrophil-Mediated Inflammatory Skin Diseases...
Other Specified Inflammatory Disorders of Skin or Subcutaneous TissuePyoderma Gangrenosum26 moreThis study investigates the genetic architecture of Neutrophil-Mediated Inflammatory Skin Diseases. After collecting informed consent, all patients' clinical phenotype is graded at inclusion with a detailed case report form and a discovery cohort formed based on the certainty of diagnosis. The DNA of patients in the discovery cohort is analyzed by whole exome sequencing which identifies all protein-coding genetic variants. Subsequently, statistical burden tests are going to identify enrichment of rare coding genetic variants in patients affected by Neutrophil-Mediated Inflammatory Skin Diseases. The ultimate goal is to reveal the responsible gene(s) that may then be targets for clinical intervention.
The Lolland-Falster Health Study
Impaired HealthDisease13 moreThe study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
Evaluation of the Interest of a Specialist in Dermatology for Dermatopediatric Consultations
Dermatologic DiseasePediatric ALL1 moreDermatologic diseases, of very different etiology and variable severity, represent a major motivation for consultation (in private consultations and in emergency departments), thus leading pediatricians to frequently turn to dermatologic advice. The principal aim is to estimate the degree of concordance of the main diagnosis between a pediatrician and a pediatric dermatologist. The secondary aims is to estimate the degree of concordance of the treatment, advices and follow-up.
A Nutritional Trial on Effect of L. Rhamnosus Yoba on RTI and Other Health Outcomes Among Children...
Skin DiseasesRespiratory Tract Infections1 moreThis is a nutritional observational trial with two arms: 1) Intervention arm of Probiotic Yoghurt containing Lactobacillus rhamnosus yoba 2012 and 2) Control arm of milk. About 500 children in each arm will be enrolled. Children will be enrolled in the yoghurt or the milk arm, based on the preference of the school and the parents in response to a sensitization campaign of a non-governmental organization (NGO) in the region. This selection will therefore be non-randomized and non-blinded. Within one school, all children will be enrolled in the same arm. The children will be monitored for 3 weeks in the baseline. Subsequently, the children will consume either 100ml of yoghurt or 100ml of milk, once per day for five days per week for nine weeks, while being continuously monitored. The milk and the yoghurt will be locally sourced in the district where the schools are located.
COVID-19 and Rare Skin Diseases European Observational Study During an Epidemic
Rare DiseasesThis is a European observational cohort study (data research) involving multiple centres to look at the potential impact of COVID infection on patients with rare skin diseases examining factors such as comorbidity, protection factors, and clinical and/or therapeutic factors. The data collected may provide additional information on the situation of patients and, on a wider basis, provide useful data applicable to the general population.
A Patient Reported Outcome Measure for Vulval Conditions
Vulval DermatosesVulval Pain SyndromesTo create a new patient reported outcome measure in the form of a questionnaire, which will accurately reflect the profound impact that vulval dermatoses and vulval pain syndromes have on patients' quality of life
Subclinical Nail Involvement in Relevant Skin Diseases
Nail DiseasesOnychopathies constitute one of the major challenges faced by a dermatologist in terms of its early detection and diagnosis . Many disorders can affect the nails, including deformity and dystrophy, infections, and ingrown toenails. Infections can involve any part of the nail and may or may not change the nail's appearance. Most nail infections are fungal (onychomycosis), but bacterial and viral infections occur .
Detection of Skin Epithelial Barrier in Patients With Allergic Skin Disorders
Atopic DermatitisSkin InflammationThe primary function of epithelial tissues is to form a barrier between the body and the external environment, in order to protect the internal tissues from environmental stresses, by minimizing water loss and preventing the entry of pathogens, pollutants and allergens. Allergic disorders, such as atopic dermatitis, have been associated to an impaired epithelial barrier function. Indeed, defects in the epithelial barriers allow tissue-damaging factors to enter the tissue and thus activate the immune response. This study aims to establish a method to assess the epithelial barrier function in vivo by electrical impedance (EI) spectroscopy, a new technique for the characterisation of epithelial tissue. By this technique, a harmless electrical signal is sent through the skin and the response of the tissue is analysed, which is influenced by several cellular properties, such as shape, orientation and size. In order to validate this technique, skin of mice was treated with some molecules able to destroy the epithelial barrier. The investigators observed that, after damaging the barrier, a decrease of the EI can be detected, consistent with the type and degree of the damage. Based on this result, the investigators believe that this technique is a good candidate as an in vivo method to determine skin barrier defects, which might be used in the future as an early diagnostic tool for the prediction of the risk to develop atopic dermatitis in young subjects, allowing the possibility to apply in time possible preventive measures. In addition, this technique might be suitable for the evaluation of a given therapy during the hospitalisation. To confirm this hypothesis, in the present study patients with atopic dermatitis will be recruited. EI measurements will be performed in both lesional and non-lesional skin and values will be compared in order to detect any difference in the electrical response due to the inflammatory state. In addition, in order to evaluate whether these patients have an appreciable defect in their skin electrical behaviour, the investigators will compare non-lesional and lesional skin of patients with skin of healthy volunteers. Peripheral venous blood and skin biopsies will be collected, in oder to characterise several immune cell populations, to detect specific skin barrier mutations and to measure serum cytokines and immunoglobulins. These and some other parameters and will be analysed in order to identify a possible correlation with the EI.

Pattern of Skin Disorders in Geriatric Population
Geriatric Skin DisorderIn this study, the investigators attempt to determine the frequency of dermatologic diseases in geriatric patients, and search for seasonal, age-related, gender-related and socio- demographic differences in geriatric patients attending the outpatient clinic of the Department of Dermatology, Venereology and Andrology in Assiut University Hospital.
