Filter by:This descriptive cross-sectional single center study will be conducted at Angers Maternity Unit. It pertains to the ways in which healthcare professionals represent congenital birthmarks found in newborns. It is our assumption that health professionals may have a tendency to engage in inappropriate behavior when dealing with congenital birthmarks due to lack of knowledge. We make the presumption that insufficient knowledge causes difficulties in managing these birthmarks. Data as to representation of birthmarks in newborns by health professionals will be collected using a semi-quantitative questionnaire. This study constitutes preliminary research work, with a view to creating a professional development plan if necessary.
1. Evaluation of fractional Co2 laser as a treatment option for wide pores in skin type (III - VI) 2. Evaluation of mesobotox as a new modality for improving wide pores appearance. 3. Comparison of both treatment modalities in treatment of enlarged pores.
Photoacoustic imaging (PAI) is an emerging method which combines light and ultrasound to assess the blood content and oxygenation of the body. Light is absorbed by the blood, leading to the generation of ultrasound, from which the levels of oxygen can be derived. This high sensitivity to blood has seen it applied in multiple clinical trials for the assessment of a number of conditions including breast cancer assessment. However, the accuracy of the measurements and image quality is known to decrease as you look deeper into the body because light intensity decreases. Melanin in the skin is known to absorb light very strongly and so there is considerable concern that this may bias measurements made in people with darker skin tones compared to those with lighter skin tones. In this pilot study, we intend to recruit volunteers with a wide range of skin tones and vitiligo. We will scan a number of blood vessels and muscles using PAI and evaluate the photoacoustic measurements of blood content and oxygenation to identify, and ultimately correct for, biases in advance of further clinical studies.
Existing methods of diagnosing and treating skin lesions are either surgical, which enables an histological diagnosis or destructive (electrodesiccation, liquid nitrogen, laser, caustics) with no possibility of obtaining histology. The ingredients of current formulations for in-vivo skin fixation (Mohs, Solcoderm) are unstable, inconvenient for application and painful - therefore their use was abandoned. The investigators will examine the safety of stable formalin-free formulations for in-vivo fixation of human skin lesions .These formulations were safe and had a rapid onset of fixation effect in in-vivo animal studies.
