Filter by:The primary objective of this study is to evaluate the effects of a novel sunscreen formulation by assessing the extent of ultraviolet radiation (UVR)-induced direct and indirect cellular and DNA damage to human skin, in the presence vs absence of the sunscreen, in a population of healthy adults with fair skin (Fitzpatrick Scale type I, II or III).
To demonstrate the safety and effectiveness of the VIO device in obtaining in vivo images that show tissue features including epidermis, dermis, collagen, blood vessels, and/or pigment. To demonstrate that the tissue features identified on the images obtained with the VIO device align with the corresponding pathology images procured from the skin biopsy. To evaluate the ability of blinded readers to correctly identify tissue features on images obtained with the VIO device.
Patients will be randomized either to receive standard daily dressing or hydrocolloid dressing using a randomization generator. After closing the wound with the sutures,the scar will be covered by a hydrocolloid dressing, which will be left in place for 7 days(Experimental) or the standard dressing (Control) that will be covered with petrolatum jelly and bandaging during this time period, which has to be re-applied daily. Patients and dermatologic surgeons will then complete surveys 7 days, 30 days, and 90 days after surgery to evaluate the cosmetic appearance of these scars.
The overall objective of this study is to investigate the potential for the VIO System to display microscopic skin structure in people of different age, sex, race, and skin health.
In this clinical feasibility study the investigators will test and compare two advanced optical imaging technologies, lipid and RNA tape stripping with regards to diagnostic accuracies for fast bedside diagnosis of pigmented skin tumours.
Americans who work outdoors are exposed to an extreme amount of solar ultraviolet radiation over a lifetime that substantially increases their risk for developing skin cancer. In Phase I, the feasibility of a virtual learning environment (VLE) for distributing our effective Sun Safe Workplaces (SSW) intervention to American employers will be established with input from senior managers and Hispanic and African American outdoor workers and development and evaluation of a prototype of the SSW Works VLE. In Phase II, the full SSW Works will be produced and tested for effectiveness at improving outdoor workers' sun protection in a randomized trial enrolling employers nationwide.
Medical imaging commonly involves the use of radiation, such as x-rays, that can give detailed images of internal structures of the body but can carry a small risk of tissue damage due to the radiation involved. As such, the number of x-rays and computed tomography (CT) scans that an individual can have has to be minimised. Methods have recently been developed that make use of electromagnetic radiation for imaging purposes at terahertz (THz) frequencies, the region of the spectrum between millimetre wavelengths and infrared. Terahertz spectroscopic imaging uses low power levels such that adverse effects on tissues are insignificant and is safe for in vivo imaging of humans [1]. The terahertz region is between the radio frequency region and the optical region generally associated with lasers. Both the IEEE RF safety standard and the ANSI Laser safety standard have limits into the terahertz region. The focus of this project is to investigate THz spectroscopic imaging as a new and powerful tool for analysing skin properties, termed "THz skinometry". The novelty in this project lies in tailoring the instrumentation and algorithms of THz scanning to accurately measure properties of human skin (e.g. hydration levels and skin thickness) in vivo. The customised non-contact and pressure-controlled contact THz probes developed will be able to do spectroscopic measurements of skin in vivo at the molecular level. This will be the first demonstration of in vivo THz imaging of skin globally and will facilitate quantitative characterisation of skin in a way that has hitherto not been possible and could lead to a step change in THz technology usage (similar to that currently used in airport security scanners).
Investigators hypothesize that the introduction of basic science explanations within the instructional design of case-based training in visual diagnostics will improve students' learning curves, retention, and retrieval of knowledge/skill following a washout period. Research question: In a group of medical students with limited dermatological training, what is the effect of integrating biomedical causal explanations of visual criteria during a prolonged case-based skin cancer training program in visual pattern recognition when compared with an identical instructional design without biomedical explanations? How will the displacement of students' cognitive resources from practicing pattern recognition towards understanding the pattern, affect their learning behavior, learning curve (accuracy and time per diagnosis), and retrieval of pattern recognition skills following a washout period? The above-mentioned research questions will be tested through a randomized trial with an allocation ratio of 1:1. All participants will be trained in skin cancer diagnostics through a mobile application that offers simulation training and learning through written modules about the various differential diagnoses. Approximately half of the participants will be subject to a written content that displays the dermoscopic visual criteria without an explanation while the remaining half will be subject to the dermoscopic criteria + an explanation of the underlying cause. The training program consists of 500 training cases, a 14 day wash-out period, and a final training session of 100 cases.
Skin cancers are the most common of all cancers. Their incidence has increased sharply over the decades.This increase in incidence partly reflects an aging population and behavioral patterns such as repeated exposure to the sun. Indeed, exposure to UV rays is the predominant factor involved in the pathogenesis of these tumors, hence the fact that they mainly develop in photo-exposed regions such as the cephalic extremity. The objective of this study is to provide an epidemiological analysis of tumors in the populations of both CHU Brugmann and St Pierre hospitals.
Background: The worldwide incidence of skin cancer has been rising for 50 years, in particular the incidence of malignant melanoma has increased approx. 2-7% annually and is the most common cancer amongst Danes aged 15-34. Currently there is a significant amount of misdiagnosis of skin cancer and mole cancer. Our aim is to improve general practitioners' diagnostic skills and accuracy of skin and mole cancer. Research questions: In a population of Danish General Practitioners (GPs) what is the dose/response effect of hours spent with an educational platform that offers AI augmented training and clinical feedback on their diagnostic accuracy and accurate clinical management (treatment, dismissal, referral)? Does access to an educational platform that offers AI augmented training and clinical feedback increase the number of malignant skin lesions referred by Danish GPs without simultaneously increasing the number of incorrect benign referrals? Can the participating GPs clinical accuracy be predicted from the MCQ-score by comparing their quiz answers and diagnostic accuracy on their registered lesions with their score on the MCQ? Method: 90 Danish GPs will at baseline, 1 month and end of trial answer a Multiple Choice Questionnaire (MCQ). There is no change to current clinical practice, but all participating doctors will be asked to register a clinical picture and a dermoscopic image as well as basic information about the lesion and patient (age, gender, location and diagnosis) of all skin lesions examined due to a suspicion for non-melanoma or melanoma skin cancer, raised by the GP or patient. GPs in the intervention group are besides the registration application (R-app) given access to an AI augmented training and clinical feedback through an educational smartphone app (E-app). Within the E-app the doctor can access quizzes on a library of 10,000+ skin lesions, written articles about the 40 most common skin lesions, and a clinical feedback module that gives the GP feedback on their registered skin lesions. Feedback on skin lesions with the registered clinical management of referred/excised/biopsied will be provided continuously by independent experts in skin cancer diagnostics (>10 years of experience) through a web-based review system developed by our group. Feedback on the remaining registered cases are withheld until the end of the study period. This is done to simulate a realistic clinical setting during the study.
