Filter by:The purpose of this study is to learn more about the potential effects of visible light on the skin. More specifically, this study will examine whether an incandescent lamp (light bulb) or LED light bulb can cause skin to become darker. Investigators will determine the minimum threshold dose required to achieve immediate pigmentation darkening (IPD), persistent pigmentation darkening (PPD), and delayed tanning (DT) for Fitzpatrick skin types IV - VI utilizing two visible light sources.
The investigators want to demonstrate that a new organization with telemedicine could rationalize the treatment pathway of patient suffering from rare skin disease. A diagnosis and a personalised treatment pathway could be performed before the consultation in the hospital.
Petrolatum is a very well-known emollient that has been used since the 1800's. Not only has it been used to help with dry skin, but it is also marketed as a substance that protects minor cuts and burns. In the past it was thought to be inferior to topical antibiotics in infection prevention for cutaneous wounds. However, in 1996 a large, multicenter trial including over 900 patients showed that petrolatum is as safe and effective as the topical antibiotic, bacitracin in preventing infections for patients undergoing dermatological surgery. In this trial, not only did the petrolatum group have similarly low rates of infection, this group also reported no cases of contact dermatitis. Aside from being more expensive than petrolatum, bacitracin and other topical antimicrobials (i.e. neomycin) have been known as common culprits of contact dermatitis. In a study done by the North American Contact Dermatitis Group between 2005-2006, 9.2 and 10% of the over 4,000 patients who were patch tested had an allergic reaction to either bacitracin or neomycin, respectively. For the above reasons, it is clear that petrolatum is an appealing alternative to topical antibiotics for infection prevention in patients undergoing dermatological procedures. This study however lacked any mechanistic analyses to provide molecular insight as to how petrolatum was effective at infection prevention. The aim of this research is to study the effect of petrolatum on innate immune reactions in the skin. In particular, petrolatum's effect on various antimicrobial peptides after contact with the skin for 3 days will be examined. This will be done through immunohistochemistry for various cellular infiltrates as well as mRNA gene expression via RT-PCR analysis for inflammatory and AMP genes. Tissue samples of petrolatum occluded skin will be compared to both healthy skin and skin under occlusion alone as controls. These comparisons will isolate the effect of the petrolatum on the skin.
The purpose of this study is to determine whether Tele-expertise would be effective and cost-effective by reducing the number of secure transportations for inmates in need of a dermatological consultation
The purpose of this study is to compare the traditional bed bath with 'washing without water' on - 1) effects on skin integrity - 2) patient and nurse satisfaction and 3) costs. In a cluster randomized trial we will randomize 50 nursing home wards (576 patients) to 'washing without water' or traditional bed baths. Bathing regimens are continued for six weeks. Whereas effects on skin damage are not likely to be specific for setting, these results can be generalized to other patient groups.
We plan to investigate the serum elevation of 25(OH)D under UVB nb and UVA1 therapy, in order to determine the effect of these nowadays frequently used wavelengths for phototherapy on vitamin D plasma levels. We hope for a better understanding of steady-state and treatment-induced levels of vitamin D changes to better recognize the impact of phototherapy on vitamin D synthesis in the skin, the dimension of vitamin D production to be expected in the course of standard phototherapy and a potential gap in vitamin D production compared to physiological needs which then should be supplemented orally.
This study will examine the structure of the receptor molecule for the herpes simplex virus (HSV) and determine if the receptor's structure is related to susceptibility to infection with the virus. There are two types of herpes virus-HSV-1 and HSV-2. HSV-1 commonly causes cold sores, and HSV-2 usually causes genital herpes. The herpes virus enters (infects) cells through protein molecules on the cell's surface. This study will explore possible differences between the structure of the HSV receptor molecule in different people to understand better how infection occurs. The study will also look at proteins on white blood cells (Fc receptors, cytokines and mannose binding protein) that may influence the risk of infection with HSV. Information from this study may lead to new treatments to prevent HSV infection. People 18 years of age and older who are infected with HSV and people who are not infected with the virus may be eligible for this study. Participants will have blood drawn to confirm whether or not they have been infected with the virus. The blood sample will also be used to study the genes for the HSV receptor, Fc receptors, cytokines, mannose binding protein and related proteins on the white blood cells. No more than 40 milliliters (8 teaspoons) of blood will be drawn. Participants who are found to have antibodies to HSV-2 will be offered counseling and advice on practicing safe sex techniques to help prevent sexually transmitted diseases, including HSV-2 infection.
