Filter by:This study is intended to evaluate the efficacy of oral supplementation of an unhydrolyzed eggshell membrane ingredient (uESM) vs placebo on both objective and subjective markers of skin aging in middle-aged and senior adults using the Cutometer® MPA 580 multi-probe system along with specially designed subject questionnaires. Secondary objectives will be to assess the benefits of uESM on the health of hair and fingernails based on a subject questionnaire.
The use of a personalized 3D model of the breast in the management of breast cancer would be very useful to help the surgeon better understand the three-dimensional location of tumors in the operative position and thus better plan incisions and dissection of the breast tissue. This could be achieved with the help of a 3D biomechanical breast model that ideally should integrate the patient-specific mechanical properties of all breast tissue structures. The elasticity of the skin and especially the consideration of factors that can make it vary with age has been little studied. However, the integration of this parameter would clearly increase the robustness of the 3D model. Main objective: To perform a pilot evaluation of the performance of the biomechanical model by integrating the biomechanical characteristics of the skin and the collagenous architecture of the breast, during the transition from prone to supine or lateral position. Secondary Objectives: To describe the values of skin elasticity and thickness at different points of the breast, in women in the general population To search for clinical factors predictive of elasticity and skin thickness To carry out a pilot description of the collagen architecture of the breast Participation in this study will be offered to all patients consulting the gynecology-obstetrics department of the Montpellier University Hospital and meeting the inclusion criteria-Visit 1: Inclusion and measurement of skin thickness and elasticity: Inclusion will take place during the follow-up consultation in the obstetrics gynecology department of the Montpellier University Hospital. The patient's written consent will be obtained after a reflection period at the end of the consultation. Measurements of elasticity and thickness will then be performed for each of the 200 patients. Skin elasticity: The patient will be installed in dorsal decubitus position, with her arms at her sides on an examination table. Measurements will be performed at 3 sites on one of the two breasts: at the areola, above the areola and below. The measurements will be performed by a single gynecologist in the gynecology department using a cutometer provided by a laboratory of Grenoble. It has just been used by the Dutch Cancer Institute in Amsterdam to measure the elasticity of the tongue in a clinical study including 10 patients. Three measurements will be performed at each site. One measurement corresponds to a 10-second suction time (progressive rise of the depression) followed by 5 seconds of relaxation of the measurement site. The duration of these measurements will be approximately 15 minutes. Skin thickness: The measurement of skin thickness will be performed using an ultrasound device available in the obstetrics and gynecology consultation department. The measurement will be performed at 3 sites. The duration of the measurements will be of approximately 10 minutes. Adverse events will be collected at the end of the measurements. -Visit 2: Within 3 weeks after the first visit. Among the 200 patients, 10 patients who should benefit from a breast MRI as part of their follow-up, will have a breast MRI in 3 different positions: prone (standard protocol) and two additional acquisitions (as part of the research) in dorsal and right lateral decubitus. This examination will be scheduled in the Lapeyronie Hospital.
The primary objective of Part A is to compare the change in elasticity measurements at baseline and at 3 months between subjects who have had a resurfacing or tightening procedure and those who have not. The secondary objective for Part A is to develop baseline elasticity scores for ages 18-35, 36-50, and 51-65 and for Fitzpatrick skin types I-II, III-IV, and V-VI. The primary objective of Part B is to compare the age of the scar and surrounding tissue with the elasticity measurements.
