Influence of COVID-19 confinement on the size of malignant skin tumours surgically removed at a Spanish hospital.

The COVID-19 pandemic required people to confine themselves to their homes where possible, and disrupted normal hospital activities. We examine whether this lockdown generated changes in the size of the tumours. We compared the dimensions of the surgically removed malignant skin tumours from the first 150 patients treated after the confinement ended in Spain (22 May 2020) with those of the last 150 patients to receive such treatment before the confinement began (13 March 2020). Data on tumour surface area were collected from pathology reports. Overall, no significant difference was seen in the tumour sizes. However, among men, the tumours removed after confinement were significantly larger (P < 0.05). Controversy exists over how the reduction in the number of tumours diagnosed during lockdowns might have influenced the characteristics of tumours. In this study, no overall difference was seen in the size of the tumours removed, although those removed from men after confinement were larger.

[Cross-cultural adaptation and Spanish validation of Patient Satisfaction Questionnaire in dermatology (PSQ-18)]. / Validación y adaptación transcultural del cuestionario de satisfacción en Dermatología (PSQ-18).

BACKGROUND AND OBJECTIVE: Patient satisfaction has become one of the most important outcome measures of quality of care. This study aimed to present the translation, cultural adaptation and validation of a Spanish version of the Patient Satisfaction Questionnaire (PSQ-18) in a sample of Spanish dermatology patients. METHODS: Cross-cultural linguistic adaptation and translation-backtranslation processes were performed following accepted international guidelines. The psychometric properties, reliability and construct validity were evaluated with Cronbach's alpha and confirmatory factorial analysis respectively. The intraclass correlation coefficient was calculated in a test-retest study, which was conducted on randomly selected participants twice with a 14-21 days interval. RESULTS: 240 participants completed the cross-culturally adapted Spanish questionnaire agreed by the researchers. Internal consistency was high (Cronbach's alpha coefficient of 0.834) and confirmatory factorial analysis showed a good model fitting to the model proposed in the original version of the scale. The intraclass correlation coefficients for all the items on the questionnaire were higher than 0.8. CONCLUSIóN: PSQ-18 proved to be a valid and reliable instrument, with psychometric properties suitable for the assessment of satisfaction among dermatology patients.

Redes sociales y dermatitis atópica: estudio descriptivo transversal / Social Networks and Atopic Dermatitis: Cross-Sectional Descriptive Study

ANTECEDENTES: Las redes sociales se han convertido en una herramienta clave para la búsqueda y difusión de información médica. OBJETIVO: Describir las características de las páginas relacionadas con la dermatitis atópica en las redes sociales, la temática de sus publicaciones y el grado de seguimiento que se realiza de ellas. MATERIAL Y MÉTODOS: Se seleccionaron páginas, grupos o cuentas relacionadas con la dermatitis atópica en Facebook, Twitter y Linkedin durante los meses de enero y febrero de 2020. De cada una de ellas se recogieron: el país de origen, año de creación, objetivo, presencia de enlaces a páginas web, existencia de correo electrónico y número de seguidores. Además, se realizó un análisis de las temáticas más frecuentes en las últimas publicaciones de las páginas con más seguidores de cada red social. RESULTADOS: Se incluyeron en el estudio un total de 257 páginas, grupos o cuentas (171 en Facebook, 59 en Twitter y 27 en Linkedin). Facebook obtuvo un mayor número medio (±DT) y total de seguidores (1416,71±3722,63). Los grupos de apoyo a pacientes fueron el tipo de página más frecuente (63%), aunque aquellas clasificadas como empresas o venta de productos obtuvieron un mayor número de seguidores (p < 0,035). Se analizaron 909 publicaciones, siendo «Información general sobre dermatitis atópica» la temática más frecuente (27,94% del total). CONCLUSIONES: Nuestros hallazgos ponen de manifiesto la importancia de definir claramente el papel y las limitaciones de estas plataformas para orientar futuras campañas de información y desarrollar nuevos modelos centrados en el paciente con dermatitis atópica

BACKGROUND: Social networks have become key tools for finding and disseminating medical information. OBJECTIVE: To describe the characteristics of social network postings on atopic dermatitis, the content that is posted, and the number of followers of pages, groups, or accounts. MATERIAL AND METHODS: We selected pages, groups, or accounts related to atopic dermatitis on Facebook, Twitter, and Linkedin during January and February of 2020. For each site, group, or account we recorded country of origin, year created, purpose, presence of links, provision of a contact email, and number of followers. We also analyzed the topics treated in recent content posts on the pages with the largest numbers of followers in each network. RESULTS: A total of 257 pages, groups, or accounts were included: Facebook, 171; Twitter, 59; and LinkedIn, 27. Facebook had the largest total number of pages and mean (SD) number of followers: 1416.71 (3722.63). Patient support groups accounted for most of the pages (63%), but businesses or product offers had more followers (P <.035). Of the 909 posts of informative content we analyzed, the most frequent topic was "general information about atopic dermatitis" (27.94%). CONCLUSIONS: Our findings show the importance of clearly defining the roles and limitations of social media platforms for designing future information campaigns and new patient-centered approaches to reaching patients with atopic dermatitis

0.5% 5-Fluorouracil/10% Salicylic Acid for the Treatment of Distal Actinic Keratoses Under Daily Practice Conditions

Background: Actinic keratosis (AKs) are sun-induced skin lesions that are at risk to progress to invasive squamous cell carcinoma (SCC). Treatments have shown to be effective on face or balding scalp area but limited data support their efficacy on distal extremities. Objective: To describe the efficacy of 0.5% 5-fluorouracil/10% salicylic acid (5FU/AS) in the treatment of distally-located AKs in daily clinical practice. Additional objectives were to review tolerance and adherence to this treatment. Methods: Retrospective review of 23 patients with distal grade II to III AKs who were treated with 5FU/AS under daily practice conditions. Primary endpoint included local skin response according to percentage on AKs reduction at week 20 (8 weeks after ending the treatment). Results: 75% (30/40) treatment areas showed a percentage reduction in AKs from to 75% to 100% at week 20. Complete response (100% clearance) was recorded in more than half of the cases (53%, 21/40). Good, partial, and low responses were respectively observed in 22% (9/40), 20% (8/40), and 5% (2/40) of patients. Most adverse events were graded as low, and adherence to treatment was considered correct in 25 patients (63%). In addition, a correct adherence to treatment was significantly related to a better response (P=0.001). Conclusion: Findings indicate that topical 5FU/AS is an effective treatment for multiple distal AKs, with a proper safety profile. J Drugs Dermatol. 2019;18(3):285-288.

INTRODUCCIÓN: La investigación clínica (IC) se centra en el estudio de los pacientes para mejorar su atención. Nuestro objetivo fue conocer qué porcentaje de las comunicaciones presentadas a las reuniones de tres secciones territoriales de la AEDV cumplen criterios de IC, su nivel de evidencia y su evolución temporal. MATERIAL Y MÉTODOS: Se revisaron las comunicaciones científicas de las reuniones territoriales gallega, astur-cántabro-castellano-leonesa (ACL) y andaluza publicadas en los suplementos de la revista Actas Dermo-Sifiliográficas (años 2000-2015). Utilizando una definición de IC previamente validada, se estableció cuáles de los resúmenes se ajustaban a dicha definición, se determinó su nivel de evidencia y la evolución temporal del porcentaje de estudios de investigación. RESULTADOS: De las 1.188 comunicaciones analizadas, el 29,6% cumplieron criterios de IC. La mayoría correspondían a un nivel de evidencia 4 (95,2%), distribuidos en un 44,2% de estudios transversales y un 55,8% de series de casos. La prevalencia de la IC en las secciones gallega, ACL y andaluza fue del 26,6% (94,7%, nivel 4), del 22,7% (97,6%, nivel 4) y del 37,2% (94,3%, nivel 4), respectivamente. El porcentaje de trabajos de IC aumentó significativamente a lo largo de los años. CONCLUSIONES: La IC representa el 29,6% de las comunicaciones en las reuniones evaluadas. La mayoría de los trabajos corresponden a series de casos y estudios transversales. Los territorios estudiados muestran diferencias en cuanto al porcentaje de IC, pero siguen una distribución similar de los niveles de evidencia. En el periodo de tiempo evaluado, el porcentaje de comunicaciones sobre IC se ha incrementado

INTRODUCTION: Clinical research is the study of patients with the aim of improving care. Our objectives were to calculate the percentage of presentations at territorial section meetings of the Spanish Academy of Dermatology and Venereology (AEDV) that described clinical research, to assess the level of evidence the research provided, and to analyze change in clinical research volume over time. MATERIAL AND METHODS: We reviewed supplements of the journal Actas Dermo-Sifiliográficas for 2000 through 2015 that contained abstracts of presentations given at the AEDV section meetings in Galicia; the area comprising Asturias, Cantabria, and Castile-Leon (ACCL); and Andalusia. We selected abstracts that met a previously validated definition of clinical research and categorized each according to level of evidence. We also analyzed how the weight of clinical research presentations changed over time. RESULTS: Of the total of 1,188 presentations, 29.6% met the criteria that defined clinical research. Most provided level-4 evidence (95.2%); 44.2% of those presentations reported cross-sectional studies and 55.8% analyzed case series. Clinical research accounted for 26.6% of the presentations in Galicia (94.7% of them, level 4), 22.7% of those at the ACCL meeting (97.6%, level 4), and 37.2% of those in Andalusia (94.3%, level 4). The proportion of clinical research increased significantly over the years studied. CONCLUSIONS: Clinical research accounted for 29.6% of the communications presented at the meetings we reviewed. Most of these presentations concerned case series or cross-sectional studies. The prevalence of clinical research presentations differed between the 3 territories studied, but the levels of evidence were similar. The proportion of clinical research in the programs of these meetings has increased over time
