Home- vs clinic-based daylight photodynamic therapy with 5-aminolevulinic acid nanoemulsion (BF-200 ALA) for actinic keratosis: A randomized, single-blind, prospective study.

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.

[Translated article] Requirements for Accessing New Dermatology Drugs in Spain: Results of the EQUIDAD Study.

BACKGROUND: Although the Spanish Ministry of Health prepares national therapeutic positioning reports (TPRs) and drug reimbursement policies, each of the country's 17 autonomous communities (ACs) is responsible for health care services and prescription requirements in its territory. The aim of the EQUIDAD study was to describe and explore potential differences in prescription requirements for new dermatology drugs across the autonomous communities. MATERIAL AND METHODS: Cross-sectional study conducted in April and May, 2023. Two dermatologists with management responsibilities from each autonomous community reported on territorial and more local prescription requirements for drugs covered by national TPRs issued between 2016 and 2022. RESULTS: Thirty-three researchers from 17 autonomous communities participated. The data submitted revealed between-community inequities in access to new drugs. Overall, 64.7% of the regions imposed additional prescription requirements to those mentioned in the TPRs for psoriasis. This percentage was lower for atopic dermatitis (35.3%) and melanoma (11.8%). The most common requirement for accessing a new drug was a previous prescription for another drug. Differences and additional requirements were also detected at the local level (i.e., differences between hospitals within the same autonomous community). CONCLUSIONS: Spain's autonomous communities have multiple regional and local prescription requirements that are not aligned with national TPR recommendations. These differences result in inequitable access to new drugs for both patients and practitioners across Spain.

A Series of 69 COVID-related Dermatoses With Biopsy, Immunohistochemistry With Anti-spike 3, in situ Hybridization and PCR: A Critical Reappraisal of Viral Involvement in COVID-19 Skin Lesions. / [Articulo traducido] Serie de 69 dermatosis relacionadas con la COVID-19 con biopsia, estudio inmunohistoquímico con anti-spike 3, hibridación in situ y PCR: Una revisión crítica de la afectación cutánea relacionada con la COVID-19.

BACKGROUND: Despite the large number of articles published on skin lesions related to COVID-19, clinicopathological correlation has not been performed consistently and immunohistochemistry to demonstrate spike 3 protein expression has not been validated through RT-PCR. MATERIAL AND METHODS: We compiled 69 cases of patients with confirmed COVID-19, where skin lesions were clinically and histopathologically studied. Immunohistochemistry (IHC) and RT-PCR was performed in skin biopsies. RESULTS: After a careful review of the cases, 15 were found to be dermatosis not related to COVID-19, while the rest of the lesions could be classified according to their clinical characteristics as vesicular (4), maculopapular eruptions (41), urticariform (9), livedo and necrosis (10) and pernio-like (5). Although histopathological features were similar to previously reported results, we found two previously unreported findings, maculopapular eruptions with squamous eccrine syringometaplasia and neutrophilic epitheliotropism. IHC showed in some cases endothelial and epidermal staining but RT-PCR was negative in all the tested cases. Thus, direct viral involvement could not be demonstrated. CONCLUSIONS: Despite presenting the largest series of confirmed COVID-19 patients with histopathologically studied skin manifestations, direct viral involvement was difficult to establish. Vasculopathic and urticariform lesions seem to be those more clearly related to the viral infection, despite IHC or RT-PCR negative results failed to demonstrate viral presence. These findings, as in other dermatological areas, highlight the need of a clinico-pathological correlation to increase knowledge about viral involvement in COVID-19 skin-related lesions.

Selection of Quality Indicators for the Certification of Psoriasis Units: The CUDERMA Project Delphi Consensus Study. / Proyecto CUDERMA: Consenso Delphi de los indicadores de calidad para la certificación de las unidades de dermatología de atención en psoriasis.

Defining quality indicators is a key strategy for ensuring the quality and standardization of health care. The CUDERMA project, an initiative of the Spanish Academy of Dermatology and Venerology (AEDV), was undertaken to define quality indicators for the certification of specialized units in dermatology; the first 2 areas selected were psoriasis and dermato-oncology. The aim of this study was to reach a consensus on what should be assessed by the indicators used to certify psoriasis units. The structured process used to do this comprised a literature review to identify potential indicators, the selection of an initial set of indicators to be evaluated by a multidisciplinary group of experts and, finally, a Delphi consensus study. A panel of 39 dermatologists evaluated the selected indicators and classified them as either "essential" or "of excellence". Consensus was finally reached on 67 indicators, which will be standardized and used to develop the certification standard for psoriasis units.

What Dermatologists Should Know About Thiazides. / Tiazidas: lo que el dermatólogo debería saber.

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.

[Teledermatology in the Health Center West Area of Granada: From primary to specialized care]. / Teledermatología en el Área Sanitaria Centro Oeste de Granada: desde atención primaria a especializada.

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.

Secukinumab: Drug Survival in Clinical Practice Settings. / Secukinumab: supervivencia en práctica clínica real.

Secukinumab, an immunoglobulin G1/κ monoclonal antibody that selectively targets interleukin 17a, is used to treat moderate to severe plaque psoriasis in adults who are eligible for systemic treatment. Indirect comparisons of the efficacy of secukinumab, ustekinumab, and anti-tumor necrosis factor agents have found lower drug survival rates for patients on secukinumab, in spite of that biologic's rapid onset of action and efficacy as demonstrated by the large number of patients reaching a Psoriasis Area and Severity Index of 90 or 100. We present data from a retrospective study of 171 patients treated with doses of 300mg or 150mg of secukinumab every 4 weeks in 5 hospitals in the Spanish autonomous community of Andalusia. Eighty-seven percent continued on treatment at 132 weeks, contrasting with reports from previously published case series.
