1. Efficacy of sunscreen with photolyase or regular sunscreen associated with topical antioxidants in treating advanced photodamage and cutaneous field cancerization: a randomized clinical trial
Abstract Background Several treatments are available for skin with advanced photodamage, which is characterized by the presence of actinic keratoses (AK). Objectives Evaluate the efficacy of using sunscreen with photolyase compared to regular sunscreen, as well as to compare the combination of a topical formulation of antioxidants versus placebo in the tre

2. Treatment of actinic keratoses and cancerization field of the face and scalp with 0.015% ingenol mebutate gel in Brazilian individuals: safety, tolerability and patients' perspectives
Abstract: Background: Actinic keratosis (AK) represents a risk of progression to squamous cell carcinoma. Ingenol mebutate gel is a novel therapeutic option for field-directed treatment. Objectives: To evaluate the safety, tolerability and patients' perspectives, related to the therapeutic success of managing AKs on the face and scalp with ingenol mebutate

3. Ingenol mebutate in the treatment of actinic keratoses: clearance rate and adverse effects
Abstract: Background: Actinic keratoses are benign intraepithelial skin neoplasms that develop in photoexposed areas and can progress to invasive carcinoma. They are seen frequently in dermatological practice, occurring in 5.1% of consultations. Ingenol mebutate (IM) was recently approved in Brazil as a topical therapy for field cancerization in actinic ker

4. Daylight photodynamic therapy - Experience and safety in treatment of actinic keratoses of the face and scalp in low latitude and high brightness region
ABSTRACT Daylight photodynamic therapy has been used in countries with high latitudes during the summer for actinic keratoses treatment with reports of similar efficacy to conventional photodynamic therapy. We evaluate its safety in 20 patients in the city of Fortaleza, a local with low latitude and high brightness. Sixteen patients did not report any discom

5. Histopathological analysis of the therapeutic response to cryotherapy with liquid nitrogen in patients with multiple actinic keratosis
Abstract Actinic keratoses are premalignant lesions of the skin caused by excessive sun exposure. Lesions may become mainly squamous cell carcinoma. Cryotherapy with liquid nitrogen is one of the main treatments. In order to evaluate the response of actinic keratosis to cryotherapy by histopathology, two lesions were selected in each of 14 patients with mult

6. Evaluation of the therapeutic results of actinic keratosis treated with topical 5% fluorouracil by reflectance confocal laser microscopy: preliminary study
Abstract Topical treatment for actinic keratosis with 5% fluorouracil has a recurrence rate of 54% in 12 months of follow-up. This study analyzed thirteen actinic keratoses on the upper limbs through confocal microscopy, at the time of clinical diagnosis and after 4 weeks of treatment with fluorouracil. After the treatment was established and evidence of cli

7. Genomic instability in human actinic keratosis and squamous cell carcinoma
OBJECTIVE: To compare the repetitive DNA patterns of human actinic keratoses and squamous cell carcinomas to determine the genetic alterations that are associated with malignant transformation. INTRODUCTION: Cancer cells are prone to genomic instability, which is often due to DNA polymerase slippage during the replication of repetitive DNA and to mutations i

8. Estudo comparativo entre terapia fotodinâmica e imiquimod tópico para o tratamento de ceratoses actínicas
As Ceratoses Actínicas (CA) são lesões hiperceratóticas, displásicas de pele. Estão comumente localizadas em áreas expostas ao sol como couro cabeludo, face e antebraços. Acredita-se que a radiação ultravioleta (RUV) cumulativa seja o maior fator etiológico, considerando-se, também, a imunossupressão e infecção pelo papilomavírus humano(HPV)

9. Effect of photodynamic therapy on the extracellular matrix and associated components
In many countries, photodynamic therapy (PDT) has been recognized as a standard treatment for malignant conditions (for example, esophageal and lung cancers) and non-malignant ones such as age-related macular degeneration and actinic keratoses. The administration of a non-toxic photosensitizer, its selective retention in highly proliferating cells and the la

10. Persistence of Human Papillomavirus DNA in Benign and (Pre)malignant Skin Lesions from Renal Transplant Recipients
An extremely diverse group of human papillomavirus (HPV) types consisting of epidermodysplasia verruciformis (EV)-associated HPV types and other cutaneous HPV types (e.g., HPV types 2 and 3) is associated with nonmelanoma cancers and benign lesions of the skin. The frequent presence of multiple HPV types in single skin biopsy specimens of renal transplant re
