Active clinical trials for "Dermatitis, Seborrheic"

To explore the efficacy and pharmacodynamic effects of omiganan topical gel in facial seborrheic dermatitis.

The purpose of this study is to determine if a topical treatment for dry scalp conditions, is safe and effective in clinically improving dry scalp conditions. The investigators will additionally examine individuals experience in using the treatment as well as any changes in the scalp microbiome before and after use studying the treatment , the investigators hope to offer children and adults a new, natural way to improve dry scalp conditions.

The goal of this research is to demonstrate the use of petroleum jelly in prevention of nonscalp seborrheic dermatitis exacerbations at the first signs of a flare. In doing so, it will decrease the chronic use of topical steroids. The use of petrolatum should have favorable outcomes for patients, without the side-effects.

Topical corticosteroids are largely used in dermatology. The major problem related to their use is that the same mechanisms underlying their therapeutic effects (antiinflammatory and antiproliferative) may lead to adverse events. Conditions sensitive to corticosteroids require formulations with mild to moderate potency while high-potency corticosteroids era required in less responsive conditions. The aim of the present study is to compare the safety and efficacy of prednisolone acetate 0.5% cream (mild-potency non-fluoridated corticosteroid) versus betamethasone valerate 0.1% cream (high-potency fluoridated corticosteroid) in the treatment of mild to moderate cortisosensitive dermatosis (atopic dermatitis, contact dermatitis, seborrheic dermatitis and psoriasis). The study hypothesis is that 0.5% prednisolone cream will be as effective as 0.1% betamethasone cream and will be an alternative option to treat corticosensitive dermatosis in body areas where the use of fluoridated corticosteroids is contraindicated, such as the face.

There's high incidence of seborrhic dermatitis among patients suffering from Parkinson's disease. Seborrhic dermatitis is caused by increased exertion of sebaceous glands. Previous studies have shown an increase of sebum excretion rate in parkinsonian pateints. Other studies demonstrated improvement in seborrhic dermatitis after anticholinergic treatment. From these studies we concluded that there might be hyperactivity of the parasympathetic system among PD patients, that cause increased exertion of sebum, therefore local injection of botulinium toxin, which inhibitis acetyl choline realese, might improve the rash of seborrhic dermatitis. 40 patients suffering from Parkinson disease or other parkinsonian disorders will participate in this study. Before treating the patients with botulinium toxin, we will measure the sebum exertion with the sebumeter device and make clinical evaluation of the rash. We will also take a picture of the rash. Then Botulinium toxin (60- 100 units) will be locally injected to the rash area. Two weeks after the injection the patients will be called and evaluated clinicly and by the sebumeter. Then they will be checked again after 3 weeks, after a month and after two, three and four month's.

Seborrheic dermatitis is a common, inflammatory skin condition that causes flaky, white to yellowish scales to form on oily areas such as the scalp or inside the ear. These scales can occur with or without underlying reddened skin. In addition to causing psychological distress, low self esteem, and embarrassment, seborrheic dermatitis is associated with scalp pruritus (itch). Treatment modalities exist to control scalp flaking and itch associated with seborrheic dermatitis, although such therapies often lose efficacy over time. As seborrheic dermatitis is a chronic (life-long) condition, better treatments are needed. The investigators propose to better characterize in subjects with seborrheic dermatitis involving the scalp versus normal scalp controls: (a) the clinical characteristics of the associated itch and (b) the pattern of nerve innervation to the scalp. In this way, the investigators hope to get a comprehensive understanding of the factors causing scalp itch with the aim that this information will create new candidates to which treatment modalities can be designed. At least 12 (up to 20) subjects and similar number of control subjects without disease will have one clinic visit including questionnaires, testing of sensation on the scalp, and biopsy of the scalp.

Observational, descriptive, retrospective, multicenter study to evaluate the safety of the treatment with Sebryl® and / or Sebryl Plus® in the management of seborrheic dermatitis and psoriasis of the scalp in routine medical practice.

A sterile swap specimen taken from the scalp of the patients with psoriasis vulgaris or seborrheic dermatitis and the volunteer control group will be examined in our study. The examples of the microbiota of the patients will be taken both the lesional scalp and the lesion-free part of the scalp. Then, the microbiota differences between the lesioned scalp and the lesion-free scalp of both groups, and the microbiome differences between the two groups and the control group will be evaluated.

Clinical single-blind randomized comparison with the overall objective of evaluating the clinical efficacy of the products Nutracort lotion and Nutracort cream in the treatment of seborrheic dermatitis on the face. Will be held clinical and perceived efficacy assessment and instrumental measurements. Each product will be applied at half face for 7 consecutive days and all applications will be monitored in the research site. 60 volunteers will be recruited. Evaluations will be held at the following times: T0 - before the initial application of the product; T1 - 24 hours after starting treatment, T2 - 48 hours after starting treatment, T3 - 72 hours after initiation of treatment, T4 - 96 hours after the start treatment, T7 - 7 days after initiation of treatment.

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.
