ABSTRACT
BACKGROUND: Daylight photodynamic therapy (DL-PDT) has become one of the most effective treatments for the resolution of actinic keratosis (AK) of Olsen grade 1 and 2. Generally, PDT it is carried out in a clinic setting, which involves the patient's and their caregivers commuting to the hospital as well as a significant use of resources to carry it out within the clinic setting. OBJECTIVES: To determine the efficacy and safety of a home-based treatment of AK with DL-PDT with the BF-200 ALA gel compared to a clinic-based setting. METHODS: The study was performed as a randomized, single-center, non-inferiority clinical trial with two parallel groups. 9 patients received one clinic-based DL-PDT (group 1) and 11 patients received one session of home-based DL-PDT (group 2). The primary endpoints were the mean AK clearance per patient and the total AK lesion clearance rate 12 weeks after treatment. The secondary endpoints were the number of remaining AKs and new AKs appearing in the treatment field 12 weeks after one PDT session. The pain during and 24 h after PDT as well as the local skin reactions were also assessed. RESULTS: The overall reduction of AK lesions per patient was similar in both groups with one PDT session. An overall AK clearance per patient of 10 ± 4.33 for group 1 versus 9.73 ± 2.9 for group 2 without statistically significant differences (p = 0.868). Regarding the clearance rate, although it was slightly higher in group 2 (71.58 ± 22.51 vs 82.1 ± 11.13), the analysis did not show statistically significant differences. The mild pain recorded during the treatment course and the mild local skin reactions were similar in both groups. Patient satisfaction was high for both groups without statistically significant differences. CONCLUSION: Self-performed home-based DL-PDT with BF-200 ALA gel is as effective as the one performed in a clinic-based setting, with a comparable safety profile, high levels of patient satisfaction and with advantages for the patients and their caregivers that can enhance patient´s adherence to the treatment.

Hydrochlorothiazide and other thiazide diuretics have been used for decades to treat high blood pressure, heart failure, and chronic kidney disease. Thiazides have been linked to photosensitivity with heterogeneous clinical manifestations and recovery times. Diagnosis can be aided by phototesting, photopatch testing, and skin biopsy. Long-term use of hydrochlorothiazide has been linked to an increased dose-dependent risk of certain types of skin cancer in recent years. In this review, we also look at other less common or lesser-known adverse effects of thiazide diuretics that have been described in isolated reports.

La hidroclorotiazida (HCTZ) y otros diuréticos tiazídicos son fármacos que se han empleado desde hace décadas para el tratamiento de la hipertensión arterial, la insuficiencia cardíaca o la enfermedad renal crónica. Las tiazidas se han asociado con reacciones de fotosensibilidad, siendo heterogéneas en cuanto a manifestación clínica y tiempo de recuperación, y en las cuales, el fototest, el fotoparche y la biopsia cutánea nos pueden ser útiles en el diagnóstico. En relación con estos fármacos, en los últimos años se ha evidenciado también un mayor riesgo dosis-dependiente de desarrollar determinados tipos de cáncer cutáneo en pacientes tratados de forma crónica con HCTZ. En esta revisión se comentan, asimismo, otros efectos adversos menos habituales o reconocidos de los diuréticos tiazídicos reportados de forma aislada en la literatura (AU)

INTRODUCTION: Teledermatology (TD) is a health tool based on the application of information and communication technologies (ICT) for the care of skin diseases at a distance, allowing a better connection between primary care professionals (PCP) and specialized care. The objective of this study was to analyze the characteristics of the teleconsultations made to our service in a period of 2years (January 1, 2018 to December 31, 2019). MATERIAL AND METHODS: The data was obtained from a TD system with dermoscopy that allows teleconsultations to be carried out asynchronously. Data were analyzed over 24months. The variables studied were the health centre of origin, the diagnostic suspicion of the PCP, the time and type of response, and the clinical judgment issued by the dermatologist. RESULTS: Between January 1, 2018 and December 31, 2019, a total of 3,294 teleconsultations were received. 24.76% were referred to the dermatology consultation, while 25.63% required subsequent follow-up electronically. The most frequent diagnostic suspicion by the PCP was that of benign pathology (54.71%). The most frequent dermatological clinical judgment was that of seborrheic keratosis (20.19%), followed by actinic keratosis (14.02%), acquired common melanocytic nevi (13.24%) and basal cell carcinoma (8.98%). CONCLUSIONS: The TD system is a useful tool that allowed a quick response to a high percentage of consultations, helping to avoid unnecessary referrals and easy communication between primary and specialized care. It also allows prioritizing those patients with malignant tumour pathology.
