Filter by:The goal of this clinical trial is to compare the effectiveness and safety of two treatments-cryotherapy and 5-Fluorouracil (5-FU)-for actinic keratosis, a common skin condition caused by long-term sun exposure. Cryotherapy is a treatment that uses extreme cold produced by liquid nitrogen to freeze and destroy abnormal cells, and 5-FU is a topical cream applied to the skin to treat lesions by interfering with cell growth. The main questions this trial aims to answer are: - Which treatment, cryotherapy or 5-FU, is more effective in reducing the number of actinic keratosis lesions? - What are the side effects associated with each treatment? - How do these treatments impact patient satisfaction, cosmetic outcomes, and health-related quality of life? Participants will: - Undergo a baseline assessment where their demographics information such as age, sex, race, smoking status, and medical history are recorded, along with the number and severity of actinic keratosis lesions. - Receive both cryotherapy and 5-FU, with each treatment applied to different areas of their body. The area of the body to receive each treatment is decided by a random process (like flipping a coin). - Complete weekly surveys to monitor for side effects during and after the treatment period. - Return to the clinic for follow-up assessments at 3 months and 12 months.
The purpose of this study is to determine if the Fractionated Laser Resurfacing (FLR) procedure can protect one forearm/wrist from precancerous actinic keratosis (AKs) as well as prevent skin cancer in older subjects with active AKs. This study builds on a similar study ongoing at the Dayton Veterans Administration dermatology clinic. This study is also testing if a photograph of the skin can be used to predict where the AKs and an skin cancers will form.
Open-Label study evaluating safety and efficacy of SM-020 Gel 1.0% in subjects with Seborrheic Keratoses and Non-Melanoma Skin Cancers (i.e. Basal Cell Carcinoma and Squamous Cell Carcinoma In Situ). Subjects will be enrolled into 1 of 5 cohorts. Each cohort will enroll approximately 5-10 subjects with at least 1 eligible lesion to be treated. A maximum of 5 lesions may be enrolled per subject. Treatment for all subjects and all lesions will be twice daily for approximately 28 days. Post treatment, residual lesions may be excised per standard of care for histological evaluation. The duration of the study is estimated to be approximately up to 12 weeks from the beginning of the Screening period until the last subject's last visit.
Application of Lipikar Baume AP+M at least twice daily for 4 weeks on one of the two arms according to a randomization scheme The purpose of this study is to observe the skin barrier function, transepidermal water loss and microbial changes in study participants with actinic field damage of both arms. It's a randomized, evaluator blinded, intra-individual controlled study conducted in one center in Germany, in adult subjects having AK (grade I to III) lesions on the forearms and back of hands and meeting specific inclusion/exclusion criteria. A total of 20 subjects will be enrolled. The study design consists in 4-week evaluation period, with 2 visits per subject: Screening/Baseline (Day 0, Day 28 (end of Lipikar Baume AP+M application)).
The goal of this observational study is to understand the perspectives and needs of patients with genodermatoses and their partners who wish to have children, regarding their decision-making process and their consideration of reproductive options. Additionally, the investigators aim to investigate the level of knowledge and perspectives of healthcare professionals (such as clinical geneticists, dermatologists and other clinicians involved), and want to explore to what extent patients and their partners are well informed about these reproductive options. To achieve this, the investigators will conduct individual semi-structured qualitative interviews with participants affected by genodermatoses (and their partners) and with healthcare professionals.
The goal of this observational study is to learn about the indications for prenatal diagnostics and preimplantation genetic testing for patients/couples affected by an inherited skin disease, and evaluate the clinical outcomes of these reproductive options. By providing a complete overview, the investigators aim to improve reproductive counselling for these patients/couples with a desire to have children. To achieve this, the investigators aim to retrospectively collect data from a cohort of patiens/couples affected by an inherited skin disease on a national level (in the Netherlands) and also an international level from various countries in Europe.
This clinical trial aims to assess the efficacy of Optical Coherence Tomography (OCT) in the early diagnosis of oral cancer. It focuses on Oral Potentially Malignant Disorders (OPMDs) as precursors to Oral Squamous Cell Carcinoma (OSCC). Despite the availability of oral screening, diagnostic delays persist, underscoring the importance of exploring non-invasive methodologies. The OCT technology provides cross-sectional analysis of biological tissues, enabling a detailed evaluation of ultrastructural oral mucosal features. The trial aims to compare OCT preliminary evaluation with traditional histology, considered the gold standard in oral lesion diagnosing. It seeks to create a database of pathological OCT data, facilitating the non invasive identification of carcinogenic processes. The goal is to develop a diagnostic algorithm based on OCT, enhancing its ability to detect characteristic patterns such as the keratinized layer, squamous epithelium, basement membrane, and lamina propria in oral tissues affected by OPMDs and OSCC. Furthermore, the trial aims to implement Artificial Intelligence (AI) in OCT image analysis. The use of machine learning algorithms could contribute to a faster and more accurate assessment of images, aiding in early diagnosis. The trial aims to standardize the comparison between in vivo OCT images and histological analysis, adopting a site-specific approach in biopsies to improve correspondence between data collected by both methods. In summary, the trial not only evaluates OCT as a diagnostic tool but also aims to integrate AI to develop a standardized approach that enhances the accuracy of oral cancer diagnosis, providing a significant contribution to clinical practice.
The aim of the study is to evaluate efficacy and safety of bimiralisib gel treatment for treatment of actinic keratosis (AK) on the face and/or scalp and/or back of hands
This study is conducted in one center in Germany, in adult subjects having actinic keratoses (grade I or II) lesions on the scalp and meeting specific inclusion/exclusion criteria. The purpose of the study is to evaluate a holistic management (efficacy, tolerability and lesion cosmetic outcomes) of Tolak® treatment.
This study aims to assess the long-term efficacy and safety of ultrapulse carbon dioxide (CO₂) laser excision in the treatment of eyelid tumors, including xanthelasma, pigmented nevi, keratoses, and so on.
