Active clinical trials for "Dermatitis"

Radiodermatitis and radiation mucositis were the most frequent side-effect during the course of radiotherapy, especially when concurrent chemoradiotherapy applied. Since reactive oxygen species formed upon radiation therapy play a central role in initiating and driving the detrimental signaling events, antioxidant supplementation is thought to provide a photoprotective effect against radiation. Green tea extract has been shown to have antioxidant and anti-inflammatory effects on various types of cells. To evaluate the safety and efficiency of green tea extract in the treatment of radio dermatitis and radiation mucositis, the investigators conducted this phase Ⅰ,II study using topical EGCG in cancer patients receiving radiotherapy or concurrent chemoradiotherapy .

Capecitabine is a drug that produces dermatologic toxicity frequently (palmoplantar erythrodysesthesia, rash , alopecia , erythema , dryness, pruritus, hyperpigmentation , rash, peeling , dermatitis , abnormal pigmentation, and less often blistering, skin ulcers , photosensitivity reactions, swelling of the face and purple) . The impact in patients' quality of life is great, so We had decided to conduct a randomized clinical trial to evaluate the effectiveness Mary D' uol balm preventing dermatologic toxicity in patient treated with capecitabine . Design: Randomized clinical trial phase II, in parallel and double-blind groups Target population : Patients with colon cancer stage II or III ( Dukes' C ) , who will initiate treatment with capecitabine monotherapy. Inclusion criteria: Over 18 years, II or III colon (Dukes' C) colon cancer, primary diagnosis, capecitabine monotherapy, sign the informed consent. Primary endpoint: Dermatologic toxicity (yes / no) Statistical analysis: The primary endpoint (percentage of patients that develop dermalogic toxocity in both groups) will be analyzed by a logistics regression model

The purpose of this trial is to evaluate the phototoxic potential of a single application on healthy skin of LEO 29102 cream in different doses.

THe study seeks to determine if pimecrolimus has a positive effect on increasing antimicrobial peptide expression and reducing vaccinia virus growth in the skin explants from patients with atopic dermatitis.

Cytokine Production Patterns in Patients with Systemic Mastocytosis Compared with Atopic Dermatitis and Healthy Individuals Summary: This study will examine how mast cells (cells involved in allergic reactions) migrate and multiply in the skin of patients with mastocytosis, a condition characterized by too many mast cells in the body. The mast cells tend to multiply in the skin, causing dark, itchy skin spots known as urticaria pigmentosa. This study will determine if the skin of patients with mastocytosis produces chemicals called cytokines that cause mast cells to migrate to the skin and multiply. The findings will be compared with those from normal volunteers and patients with atopic dermatitis, a skin disease characterized by recurrent itchy rash usually seen in people with a family history of allergies. Healthy volunteers, patients with mastocytosis and patients with atopic dermatitis 18 years of age and older may be eligible for this study. Participants will have the following tests and procedures: Suction blisters - Two to eight small blisters will be raised on the forearm using gentle suction. The fluid in the blisters will be collected with a syringe to study the chemicals produced by the skin. The tops of the blisters may be removed for research. Template study - Patients with high cytokine content in the blister fluid may have a template study. For this procedure, a plastic block (template) with holes matching the blister sites is placed over the blistered area. The wells of the template are filled with salt water and the fluid is removed with a syringe at 3, 8 and/or 24 hours. Patients are hospitalized for 24 hours for this study. Skin biopsy - A skin biopsy will be done to correlate cytokine levels with the number of mast cells in the skin. An area of skin is numbed with an anesthetic and a small circular area about the size of a pencil eraser is removed, using a sharp cookie cutter-type instrument. Blood draw - About 4 tablespoons of blood will be drawn to compare the chemicals in the blood with those in the blister fluid. The blood will also be analyzed for a complete blood count, clotting factors and substances that may be elevated in people with allergies.

The use of a suction blister apparatus has facilitated study of the immunologic capacity of human epidermal cells. We have been able to prepare purified populations of these cells after blister formation. Specifically, using the blister tops, we are able to enrich for epidermal Langerhans cells which are very potent stimulators in antigen presenting assays. Thus, this normal volunteer study provides an important source of fresh epidermal tissue from which we can study normal epidermal Langerhans cell function. In addition, we have recently used blister roofs in important experimental models of HIV-1 transmission. There is no other method available for assessing the biologic function of freshly isolated Langerhans cells without altering their milieu. It is a very safe and effective way to obtain human epidermal samples.

Allergies are increasing worldwide affecting 30-40% of the population. Among this, Atopic Dermatitis (AD) is the earliest and the most common manifestation of allergic diseases (prevalence 20%). Recent studies have shown that allergies were associated with a disruption of the gut microbial 'balance' suggesting that the use of nutritional intervention very early in life may restore an optimal pattern of microflora aiming at improving the host's health. So far, most human intervention studies have mainly focused on improving postnatal infant colonization. Our study will test the hypothesis that a maternal antenatal prebiotics (GOS/inulin) supplementation may be superior to placebo for AD prevention in high-risk children.

To evaluate the performance of Xonrid® in the prevention and treatment of G2 radiation dermatitis in breast and head & neck cancer patients.

Atopic dermatitis represents a real challenge in public health as it affects a large percentage of children and adults. Affected individuals must cope with a significant psychosocial burden, in addition to dealing with the medical aspects of the disease. The purpose of this exploratory study is to collect clinical severity AD data, using PO-SCORAD (self-assessment by the subjects), SCORAD evolution, instrumental measurements and treatment follow up of subjects. The future objective is to develop a personalised prediction model of AD flares in order to improve management of AD by more accurate severity evaluations by the subject and the physician. Development of a method of early detection of flares will open new treatment pathways for AD management.

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.
