The goal of this clinical trial is to compare the 2 different prototype of cytoselectivecryotherapy devices (name of the devices : CRYONOVE) use in brown spots on the face of subject from different ethnicities. The main questions it aims to answer are: - the tolerance of 2 prototypes of cyto-selective cryotherapy treatments - the performance of 2 prototypes of cyto-selective cryotherapy treatments Participants will be treated for each spots with a definied prototype during 6 treatment visits. Researchers will compare the tolerance and performance of the 3 prototypes.
The goal of this clinical trial is to compare the 3 different prototype of cyto-selective cryotherapy devices (name of the devices : CRYONOVE) use in brown spots on the face of subject from different ethnicities. The main questions it aims to answer are: - the tolerance of 3 prototypes of cyto-selective cryotherapy treatments - the performance of 3 prototypes of cyto-selective cryotherapy treatments Participants will be treated for each spots with a definied prototype during 6 treatment visits. Researchers will compare the tolerance and performance of the 3 prototypes.
This trial is a single-center, prospective self-controlled study. The study proposes to recruit 30 patients with solar lentigo on both sides of the face. Patients are randomly assigned to be treated with high-intensity focused ultrasound (MFUS One, Hunan Peninsula Medical Technology Co., Ltd., China) on one side, and the other side is not treated. The Lab* values of the lesion area and the area around the lesion are detected separately using 3nh HIGH-QUALITY COLORMETER colorimeter (Konica-Minolta Company, Japan), and skin lesion images are collected with dermatoscope and VISIA® (Canfield Company, USA). Measurements of Lab* values and related images at the same location, along with adverse events, physician and subjective global aesthetic improvement scale scores are recorded before and at week2, week 4, week6. At the end of the follow-up on the treatment side, the same parameter treatment is provided for the untreated side, and the corresponding observation items are recorded for the patient before treatment, and at week2, week4, and week6 respectively.
Reflectance confocal microscopy (RCM) is the reference in vivo imaging technique for identifying malignant melanocytic tumors prior to surgical excision. However, it is not widely used due to its high cost and highly technical and time-consuming nature. In addition to RCM, we currently use 2 less expensive dermatoscopes that also allow in vivo diagnosis: super-high magnification dermoscopy (D400) and Fluorescence-Advanced videodermatoscopy (FAV).
Mohs micro-graphic surgery (Mohs) is a tissue-sparing, surgical treatment for different types of skin cancer (e.g. basal cell carcinoma, squamous cell carcinoma, lentigo maligna (melanoma). It is a procedure performed with frozen sections. Slow Mohs, a variant of micro-graphic surgery, is performed by formalin fixation and paraffin-embedded sections. Both in Mohs and Slow Mohs tumor margins are assessed to achieve complete removal. This study aims to investigate the clinical presentation and outcomes (i.e. complications and recurrence rates) in patients treated with Mohs or Slow Mohs in the dermatology department of the Maastricht University Medical Center+ in Maastricht, the Netherlands.
CS5_4 study aim to evaluate the performance and the tolerance of 3 prototypes of cyto-selective cryotherapy treatments applied on the brown spots on the face and hands of asian ethnicity skins (chinese). A brown spot is defined as solar or senile lentigo (SSL) and post-inflammatory hyperpigmentation (PIH). Each treatment corresponds to a combination of a specific sequence of cryogenic spray and of a frequency of application. Each spot will be treated by a defined prototype (always the same device on the same spot all along the study). The study will evaluate the following prototype : - Prototypes 1 - Prototypes 2 - Prototypes 3
CS5_7 study aim to evaluate the tolerance and to adjust the mode of administration of two conditions of cryotherapy treatment applied on the brown spots of the face and hands with 1 prototype (816-v1). A brown spot is defined as solar or senile lentigo and post-inflammatory hyperpigmentation (PIH). The study will evaluate the following prototype : • Prototypes from (816-v1 201) to (816-v1 290)
CS5_8 study aim to evaluate the tolerance and to adjust the mode of administration of 2 different conditions of cryotherapy treatments applied on the brown spots of the face with 1 prototype (816-v1). Each treatment corresponds to a specific frequency of cryogenic spray application. The study will evaluate the following prototype : • Prototypes from (816-v1 301) to (816-v1 355)
CS5_3 aims to evaluate the tolerance and to adjust the mode of administration of 4 different conditions of cryotherapy treatments applied on the brown spots of the face and hands with 3 prototypes. A brown spot is defined as solar or senile lentigo and post-inflammatory hyperpigmentation (PIH). Each treatment corresponds to a combination of a specific sequence of a cryogenic spray and of a frequency of application. The study will evaluate 3 prototypes : - Prototype 1 : SN from (816-v1 001) to (816-v1 100) - Prototype 2 : SN from (816-v1 101) to (816-v1 150) - Prototype 3 : SN from (816-v1 151) to (816-v1 200) Prototypes will be applied on the face and hands according to specific frequencies of application.
