Filter by: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).
A double-blind within person randomized controlled trial study was conducted on 90 wounds in 22 subjects. All wounds were randomized to receive either sodium fusidate ointment or petrolatum following cauterization.
Aim of study: To collect data for a new image-guided diagnostic algoritm, enabling the investigators to differentiate more precisely between benign and malignant pigmented tumours at the bedside. This study will include 60 patients with four different pigmented tumours: seborrheic keratosis (n=15), dermal nevi (n=15), pigmented basal cell carcinomas (n=15), and malignant melanomas (n=15), these four types of tumours are depicted in Fig.1, and all lesions will be scanned by four imaging technologies, recruiting patients from Sept 2019 to May 2020. In vivo reflectance confocal microscopy (CM) will be used to diagnose pigmented tumours at a cellular level and provide micromorphological information5;6. Flourescent CM will be applied to enhance contrast in surrounding tissue/tumours. Optical coherence tomography (OCT), doppler high-frequency ultrasound (HIFU) and photoacustic imaging (also termed MSOT, multispectral optoacustic tomography) will be used to measure tumour thickness, to delineate tumours and analyze blood flow in blood vessels. Potential diagnostic features from each lesion type will be tested. Diagnostic accuracy will be statistically evaluated by comparison to gold standard histopathology
The primary purpose of this trial is to evaluate Nano-Pulse Stimulation (NPS) to clear or remove Seborrheic Keratosis (SK) lesions from off-facial areas of healthy adult subjects.
This study is an open-label study designed to evaluate subject's satisfaction after treatment of seborrheic keratoses with A-101 40%.
The primary objective of this study is to evaluate the safety and effectiveness of 2 concentrations of A-101 compared to Vehicle for the treatment of 4 seborrheic keratosis (SK) Target Lesions on the trunk, extremities and face.
This is an open-label safety study. During this study, the investigator will identify 4 eligible SK Target Lesions on each subject on the trunk, extremities and face.
This is a randomized, double-blind, vehicle-controlled, parallel group study.
This is a randomized, double-blind, vehicle-controlled, parallel group study of A-101 Solution 40% compared with Vehicle Solution.
The purpose of this study is to evaluate the safety and dose-response of 2 concentrations of A-101 versus a vehicle control in the treatment of seborrheic keratosis.
