Demodex Density, Immune Response and Oxidative Stress in Rosacea Patients

Rosacea

Aim of study is to determine reactive oxygen products and antioxidant capacity with rosacea patients; to measure metalloproteinase level and inflammatory markers of immune response and investigate their corelation with demodex infestation and also investigate the role of photoaging and sebum secretion in rosacea.

Use of the SpiderMass for in Vivo Analysis of the Skin in Five Chronic Inflammatory Dermatosis

AcneAtopic Dermatitis4 more

The physiological states of the skin are characterized by a certain homeostasis linked to the balance of the metabolic pathways. When these pathways are deregulated, the proteic, lipidic and metabolic is affected. It is thus possible to follow a change in the state of the skin by looking at change in the associated molecular profile. The PRISM laboratory (INSERM U1192) in Lille has developed an innovative system laser called SpiderMass composed of 4 parts: A laser used for the micro-sampling of material in vivo, A transport transfer line of the ablated particles, A mass spectrometer that analyzes them in real time and generates the molecular profiles of the epidermis, A data analysis procedure. The SpiderMass(TM) is of great interest for the study of the skin because it allows non-invasive vivo characterization, and therefore without biopsy or sample preparation. In addition, it will complement techniques already used in the research center such as FTIR spectroscopy. Indeed, in acne studies the FTIR allows to obtain only the Fatty Acid Triglycerid ratio while the SpiderMass permits to detail these lipid classes by each observed molecule on the surface of the skin and follow their evolution.

Heidelberg In Vivo Confocal Microscopy to Evaluate the Ocular Surface Disorders of Healthy and Diseased...

Healthy IndividualsDiabetes10 more

In vivo confocal microscopy (IVCM) has been used in clinical settings for more than 25 years, and is noninvasive, rapid and easily repeatable technique to investigate ocular surface disorders. It enables morphological and quantitative analysis of ocular surface microstructure. [1-3] As the technology advances, new IVCM machine, Heidelberg Retinal Tomograph with Rostock Corneal Module (HRT-RCM), was developed. Hardware and software modifications and acquisition techniques continue to expand the applications of the HRT-RCM for quantitative in vivo corneal imaging at the cellular level. The new software can access the corneal nerve more accurate. Here the investigators proposed this Institutional Review Board (IRB) to collect healthy persons and cases of different systematic diseases as well as etiologies of ocular surface diseases.

Facial Demodicosis and Ocular Demodicosis

Demodex InfestationRosacea3 more

To understand the association between facial demodicosis and ocular demodicosis, we plan to enroll patients with facial demodicosis, ocular demodicosis, or both, in order to analyze their clinical presentations, the density of Demodex infestation over facial skin and eyelashes, and possible risk factors of the two diagnoses.

Characterization of the Facial and Gut Microbiome in Rosacea

Rosacea

Questionnaires will be completed by each member of the twin set. A board-certified dermatologist will examine each member to categorize the type and severity of their rosacea. The facial and gut microbiome will be sampled and sent for microbial analysis.
