Filter by:Arsenic is one of the largest mass poisonings in Bangladesh. Arsenic keratosis of the palm and sole is a common feature of arsenicosis. Brinjal or eggplant ubiquitous vegetable found in different parts of the world, including Bangladesh, scientifically known as Solanum melongena. A study showed ointment containing crude extract of Solanum melongena peel origin is effective in arsenic keratosis. Solasodine is one of the active compounds of Solanum melongena peel. In the current study, an ointment containing a single compound solasodine isolated from Solanum melongena peel . The ointment made from solasodine extract was distributed among arsenic keratosis patients to see the effect.
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 is a randomized clinical trial evaluating blue light 5-aminolevulinic acid (ALA) photodynamic therapy with different incubation times for the treatment of actinic keratosis. Subjects who are interested in participating, currently living in the Chicago metropolitan area, and meet inclusion and exclusion criteria will be enrolled in the study. Subjects will be randomized to either 1) zero time ALA incubation or 2) 1 hour ALA incubation. Demographic and health data will be collected prior to treatment initiation. Three visits will be conducted: screening, treatment, and follow up visit at 8 weeks. This study is a pilot study designed to determine feasibility of this procedure.
The objective of this study is to determine the efficacy, safety, and patient satisfaction of pretreatment with Picato® gel 4 days prior to methyl aminolevulinate photodynamic therapy (MAL PDT). Patients diagnosed with actinic keratosis who are eligible to receive topical treatment with ingenol mebutate (Picato®) and photodynamic therapy will act both as the test group and the control group. Each patient will have four distinct treatment areas of 25cm2 on the scalp, and/or scalp and face. Three of the treatment areas will receive Picato® 0.015% gel, MAL PDT, or Picato® 0.015% and MAL PDT combined. One area will serve as a control and will receive none of the treatments.
A multi-centre randomised controled single blind clinical phase IV trial with the aim to determine the most effective treatment in terms of lesion reduction, costs and patient satisfaction in treatment of actinic keratosis (AK), when comparing topical treatment with photodynamic therapy (PDT), 5% 5-fluorouracil (5-FU) cream, 5% Imiquimod (IMI) cream and ingenol mebutate (IM) gel.
Sequential therapy with cryosurgery and ingenol mebutate may optimize the treatment of hypertrophic AKs and also treat non-hypertrophic AKs in this anatomic location. Furthermore, use of ingenol mebutate will also be evaluated for potential treatment of subclinical lesions.
The purpose of this study is to assess the efficacy, safety and tolerability of Eryfotona AK-NMSC® topical application vs Sunscreen on cancerization field of actinic keratosis patients after 6 months of treatment.
The purpose of this study is to determine whether photodynamic therapy or CO2 laser therapy is superior in the treatment of actinic keratoses with respect to efficacy and side effects.
The purpose of this study is to determine the potential effect of topically applied 3.75% imiquimod cream on atrial ectopy in actinic keratosis (AK) patients. The primary endpoint is the change in the 24-hour supraventricular premature beat count. The secondary endpoint is the change in 24-hour supraventricular premature couplet and run counts and atrial fibrillation (% time); change in 24-hour mean heart rate; change in 24-hour ventricular premature beat count, ventricular premature couplet and run counts.
The purpose of this study is to determine whether afamelanotide (CUV1647) is effective in reducing the number of actinic keratoses and squamous cell carcinomas developing in immune compromised organ transplant recipients, who are at particularly high risk, over a 24 month test period. The number of lesions formed on the head, hands and forarms will be monitored over this 24 month test period.
