RESUMO
Actinic keratosis (AK) is one of the most frequent pathologies in clinical dermatology. Approximately 10% of the prevalence of AK occurs at 30 years of age and rises to 80% at 70 years of life. This study conducted a split-face analysis based on Photodynamic Therapy (MALA-PDT) and 5-fluorouracil (5-FU) treatments in patients with AK. Clinical and histopathological studies evaluated each treatment's efficiency and side effects. Six patients were recruited between 50 and 70 years of age for this. MALA-PDT was applied on the right side of the face. A biodistribution time of 2 h, a dose of light of 36 J/cm2 (20 min irradiation), a spot for photoirradiation with a total area of 100 cm2, and a wavelength of 635 nm were used. (LINCE equipment MMOPTICS-Brazil). By fluorescence diagnosis, clinical and subclinical AK lesions were evidenced in the area called the "cancerization field." Two cycles of MALA-PDT were performed on each patient, and 5-FU was applied twice daily for 15 days. A 2-month follow-up post-MALA-PDT and post-5-FU was carried out. The treatment based on 5-Flu and MALA-PDT clinically shows the same response, but MALA-PDT is less aggressive than 5-FU. The treatment of AK based on MALA-PDT is a practical, inexpensive, and easy-to-use technique.

BACKGROUND: Skin cancer is one of the most common cancers, and melanoma is a highly preventable cancer. In Ecuador, few studies have evaluated the awareness levels of the population about the disease. For this reason, the objective of this study was to measure the level of knowledge, attitudes, and practices regarding skin cancer and its determining factors. METHODS: A cross-sectional analysis using an online self-assessment questionnaire containing 40 questions was delivered. A total of 537 participants were included in this study. Knowledge, attitude, and practice scores were assigned to each participant based on the number of correct or appropriate responses. Logistic regression analysis was used to calculate crude and adjusted odds ratios. RESULTS: In total, 75% of participants referenced knowledge of the harmful effects related to noncontrolled solar exposure. Concerning sunscreen, 76.7% knew the reason for using it. The female group was 1.68 times more likely to get a higher score than the male group, and the groups between 61-70 and 71-80 years were 0.30 and 0.17 times less likely to get a higher score compared with the less than 20-years-old group, respectively. CONCLUSIONS: The findings of this study indicate the requirement to increase the population's knowledge about skin cancer and possible protection measures. For this reason, the prevention and health promotion programs at a national level from primary healthcare centers are recommended. Due to the limitation of the representativeness of the sample, the use of more studies among Ecuadorian residents of the low socioeconomic level and replication in different provinces of Ecuador is justified.
