Filter by:The aim of this study is to determine the erythema-reducing efficacy of a test product in two concentrations on a light sunburn induced by a sun simulator compared to an untreated control and a placebo product.
Background: In critical care medicine central venous catheters play an important role in the source of infections. In the daily routine prior to the diagnosis the suspicion of catheter related infection is discussed in the medical team due to signs of systemic inflammation or exit site infection like erythema, induration or tenderness. However, if an erythema at exit site of a central line can be quantified with a tablet camera, is unknown. Methods: Standardized set of photos will be taken of 10 central lines with a reddened exit site and 10 catheters without an erythema (as a control over time) with a tablet camera and a single-lens reflex camera. The percentage of usable images between tablet and single-lens reflex camera will be analysed. Furthermore, two independent clinical experts from dermatology will grade blinded de-identied images on a scale from 0 to 4 (0 - no erythema, 1- very faint, 2 - faint, 3 - bright, 4 - very bright). Objectives: The primary objective of this feasibility study aims to analyze the reliability of a tablet camera as a device for quantification of erythema around an exit site.
Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The disease manifests with a varied spectrum, ranging from localized tuberculoid leprosy (TT) to generalized lepromatous leprosy (LL) types. The normal course of leprosy is interrupted by troublesome immune reactions, namely lepra reactions. ENL (a type 2 lepra reaction) is an immune-mediated hypersensitivity reaction, presenting as erythematous, tender, papulo-nodules and associated with constitutional symptoms (fever, arthralgias etc). Pro-inflammatory mediators are elevated, especially tumour necrosis factor α (TNF-α), interferon-γ (IFN- γ) and interleukins (IL-2, IL-6, IL-12). LL type and high bacteriological index are considered to be risk factors for ENL. Lesions usually appear after starting MDT, although it may also be presenting feature. Diagnosis is made by characteristic lesions associated with constitutional symptoms and painful nerve thickening. Mild episodes of ENL respond to adequate rest and oral aspirin. Severe episodes necessitate anti-inflammatory drugs like corticosteroids (e.g. Prednisolone) and/or thalidomide. Use of high-dose prednisolone increases risk of steroid toxicity. Thalidomide is category X drug (unsafe in pregnancy), not freely available and has cost-limitations. Clofazimine requires higher doses, takes 4 to 6 weeks to be effective and produces gastrointestinal side-effects and skin discoloration. Minocycline has been tried as an alternative; however the drug itself has been reported to precipitate ENL in some patients. Thus, a safe and effective steroid-sparing agent for ENL remains elusive. Cyclic adenosine monophosphate (cAMP) is an intracellular signal molecule. Phosphodiesterases (PDEs) catalyse degradation of cAMP leading to its inactivation. Inhibition of PDEs leads to increased intracellular cAMP, which has anti-inflammatory actions. PDE-4 isoenzymes are the predominant cAMP degrading enzymes in most immune cells. Apremilast is an oral phosphodiesterase-4 (PDE-4) inhibitor currently used clinically for the treatment of psoriasis and other chronic inflammatory diseases. The anti-inflammatory effects of apremilast shown in-vitro includes downregulating TNF-α, IFN-γ, IL-2, IL-12 and IL-23. Although apremilast is not yet clinically indicated in ENL, its anti-inflammatory spectrum targeting the same molecules as those implicated in ENL and efficacy seen in other inflammatory conditions warrants its trial in chronic, recurrent ENL patients.
Single-blind within subject comparison study conducted to investigate the skin protectant properties of Omeza Collagen Matrix on damaged skin
The primary objective of this study was to assess the sensitization potential of Omeza Collagen Matrix compared to that of a negative control based on a Modified Human Repeat Insult Patch Test.
Consumer products or raw materials designed for consistent reapplication to areas of the skin may, under proper conditions, prove to be contact sensitizers or irritants in certain individuals. It is the intention of a Repeat Insult Patch Test (RIPT) to provide a basis for evaluation of this irritation/sensitization potential if such exists.
This research seeks to evaluate the short (i.e., after single application) and long-term (i.e., after periodic application) hydrating effect of a topical preparation containing CBD and hemp oil on the skin of the volar forearm as well as the effect on instrumentally measured erythema.
The investigators will evaluate differences in host immune responses (levels of cytokines and chemokines, representative of innate, Th1, and Th17 immune responses) in acute sera from adult patients with solitary or multiple erythema migrans.
The main objective of this study is to characterize the inflammatory proteins, gene polymorphisms, and transcriptome profiles in patients with erythema migrans to gain better insight into pathogenesis of early Lyme borreliosis and to define new immune modulators that could serve as biomarkers of disease activity.
In this study, researchers want to learn more about the effect of dexpanthenol dermal spray on skin recovery and reduction of skin redness after a dermatological procedure (non-ablative laser) on the face for treatment of fine wrinkles, scars, open pores and change of pigmentation. After the dermatological procedure, participants will return within 3 weeks for 4 visits to the study center to investigate the skin conditions such redness, irritation, softness and possible side effects. In addition, study participants will be asked about their general acceptance of dexpanthenol dermal spray.
