The potential role of topical valproate (VPA) in hair regrowth has been recently suggested. However, safety reports of VPA as a topical formulation are lacking. Therefore, in the present study, we investigated whether VPA causes skin irritation in humans. We first performed a cell viability test and showed that VPA did not exhibit toxicity toward HaCaT keratinocytes, fibroblasts, and RBL-3H mas...
Pressure sores are a severe and costly problem for many disabled individuals. There is a need for quantitative tools to assess damage produced by external loads on human skin and underlying tissues. Clinically, intensity and size of skin erythema have been used as indicators of tissue damage. Temperature is a quantifiable measure, and various studies have investigated the thermal response to lo...
Cutaneous microdialysis is a method of measuring endogenous and exogenous compounds in the dermal interstitial fluid. The microdialysis probe is inserted in the dermis using a guide cannula. The insertion trauma was studied in dorsal forearm skin in a total of 28 human healthy volunteers. Twenty-four volunteers received local anaesthesia (Xylocain 10 mg/ml) in both forearms and a microdialysis ...
Carotenoids are efficient antioxidants capable of scavenging reactive oxygen species generated under conditions of photooxidative stress. It has been shown that supplementation with high doses of beta-carotene protects skin against UV-induced erythema. This study was designed to investigate whether intervention with a natural dietary source rich in lycopene protects against UV-induced erythema ...
Natural oils are advocated and used throughout the world as part of neonatal skin care, but there is an absence of evidence to support this practice. The goal of the current study was to ascertain the effect of olive oil and sunflower seed oil on the biophysical properties of the skin. Nineteen adult volunteers with and without a history of atopic dermatitis were recruited into two randomized f...
To understand biological function of IL-6 in the skin in vivo, we constructed a vector that strongly expressed human IL-6 in keratinocytes and introduced it into rat keratinocytes in vivo by the naked DNA method. The overexpression of IL-6 induced macroscopic erythema and histologically evident keratinocyte proliferation and lymphocytic infiltration in the treated area of rat skin. Since previo...
BACKGROUND AND OBJECTIVES Objective methods to assess quantitatively port wine stain (PWS) blanching in response to laser therapy are needed to improve laser therapeutic outcome. Previous studies have attempted to assess objectively PWS color based on point measurement devices. To date, these approaches have typically been limited by a number of factors such as small test area and need for cont...
An early feature of Lyme disease is the distinctive erythema chronicum migrans. Bateman and Lawton described nine patients with Lyme disease who had unilateral or bilateral facial nerve palsies, and in three of these the palsy was associated with this skin lesion.' The induration and erythema seen in my patients may have been those of erythema chronicum migrans. Seven of the patients described ...
Case definitions for European Lyme disease have been published. However, multiple erythema migrans may pose a diagnostic challenge. Therefore, we retrospectively reviewed the clinical and serological findings and response to therapy in a cohort of consecutive 54 patients with PCR-confirmed erythema migrans, referred to a university dermatology clinic. The proportion of patients with multiple er...
