Active clinical trials for "Keratosis"

This study aims to collect data on the frequency of SCCs in the Alacare®-treated area during an interval of two years after Alacare®-PDT.

The purpose of the potential research study participant registry is to keep potential research subjects informed about any future research studies in which they may meet the criteria for enrollment. The purpose of this study is also to assist current and future clinical trials with recruitment of subjects.

The purpose of the study is to evaluate patient reported outcomes (PROs) in terms of health-related quality of life (HRQoL) among subjects with actinic keratosis (AK).

Prospective non-interventional study conducted in Australia, Brazil, Mexico and Europe to evaluate clinical practice with Metvix Daylight PDT in the treatment of mild to moderate actinic keratosis of the face/scalp and to assess physician and patient satisfaction.

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

This study examines melanoma and nonmelanoma skin cancer in people diagnosed with vitiligo compared to matched controls.

This study is to compare the ability of optical biopsy. Research can use light enters the skin, collected, analyzed by the computer, and a picture created for the pathologist to conventional histologic examination compare with the pathologist looking at the piece of tissue through a microscope makes the diagnosis.

The aim of this study is to provide this investigational drug to patients who cannot be optimally treated with conventional therapies and to collect efficacy and safety data on the use of Metvix PDT in subjects with field actinic keratoses, large/multiple superficial basal cell carcinomas (BCCs) or Bowen's disease.

The purpose of this study is to compare and evaluate the diagnostic performance of scrape cytology using two different cytological staining techniques, and to evaluate additional touch imprint cytology with that of histopathology of superficial basal cell carcinoma and actinic keratosis.

The purpose of this study is to identify the genes responsible for certain scaling disorders and other inherited skin diseases and to learn about the medical problems they cause. In some cases, these may include problems affecting organs other than the skin, such as the eyes, teeth and bones. Patients with inherited skin disorders, including Darier's disease (keratosis follicularis), lamellar ichthyosis, epidermolysis bullosa, cystic acne, and others, and their relatives may be eligible for this study. Patients will have a medical history, physical examination with particular emphasis on the skin, and routine blood tests. Additional procedures for patients and unaffected relatives may include: Blood sample collection Dental exam with X-ray of the jaw Eye examination X-rays of the skull, ribs, chest, hands, feet, spine, arms, or legs Bone density scan Photographs of the skin Skin biopsies (removal of a small tissue sample under local anesthetic) Buccal sample (gentle brushing inside the cheek to collect a cell sample) for gene studies Patients who request the results of their gene testing will be provided this information.
