Active clinical trials for "Keratosis"

Daily intake of Nigella sativa for 12 weeks is effective in the treatment of palmer arsenical keratosis

Context: Approximately 100 million people throughout the world consume water contaminated with arsenic at levels above carcinogenic thresholds, including 40 million in Bangladesh alone, with up to one-fourth of deaths attributed to arsenic exposure in the worst-affected regions. There are no proven therapies for treating chronic arsenic toxicity or for preventing arsenical cancers. Selenium has been known to counter arsenic toxicity in a variety of animal models. The investigators have recently shown in animals and humans that this effect is mediated by the formation of [(GS)2AsSe]- , the seleno-bis(S-glutathionyl) arsinium ion, which is then rapidly excreted via the hepatobiliary system. Concurrently, two Phase II studies in China and Bangladesh have suggested clinical benefit to selenium supplementation in arsenicosis patients. Objective: To assess whether daily selenium supplementation counters arsenic toxicity in patients exposed to drinking water arsenic. If proven effective, selenium supplementation might be safely and cost-effectively implemented in the worst-affected localities.

This clinical trial serves the purpose to compare the long-term effects of a treatment of actinic keratosis - your skin disorder - using Aldara® 5% cream (Imiquimod) or Solaraze® 3% gel (Diclofenac) on the face or the scalp. In particular, it should be found out whether the healing effect of these two medications on the skin lesions (i.e. the damaged skin parts) can be maintained for a prolonged period.

To identify the Maximum Tolerated Dose levels of ingenol mebutate gel after once daily treatment for 2 or 3 consecutive days and to evaluate efficacy of ingenol mebutate gel in different doses after once daily treatment for 2 or 3 consecutive days compared to vehicle gel

The purpose of this study is to determine if the new vehicle formulations containing ingenol mebutate are as safe and effective as Picato® gel 0.05% (it's current vehicle formulation) when applied to AK lesions on the forearm for two consecutive days.

The purpose of this trial is to evaluate the safety of a simultaneous treatment regimen compared to a sequential treatment regimen when two separate areas with AKs (one located on face/scalp and the other located on trunk/ extremities) are treated with ingenol mebutate gel

The main objective of this study is to evaluate the dose-response relationship of two concentrations of A-101 solution when applied to individual seborrheic keratosis (SK) lesions (target lesions) compared with a matching A-101 Solution Vehicle.

The purpose of this study is to determine if use of topical imiquimod cream after cryotherapy of actinic keratoses reduces the total number of lesions (those treated with cryotherapy and new ones) at follow-up.

The aim of this study is to evaluate the efficacy and safety of LAS 41005 compared to cryotherapy in subjects with moderate to severe hyperkeratotic actinic keratosis (punch biopsies).

The investigators hope to establish whether or not the diode laser, a longer-wavelength laser, is effective in treating keratosis pilaris, and hopefully opening a door into the discussion and management of this skin condition. The primary outcome of interest is the difference in the overall blind rater severity scores of the treated versus the untreated sites. The secondary outcome of interest is the change in the patient's self-rated severity score of the treated site. To account for potential natural disease progression or regression, the investigators will also compare patient mean changes to the mean changes in severity scores of the untreated site.
