Photoprotection Knowledge, Habits, and Attitudes Among Spanish and Italian Medical Students. / Conocimientos y hábitos sobre fotoprotección en estudiantes de Medicina españoles e italianos.

Exposure to UV radiation is a major risk factor for the development of malignant skin neoplasms. Currently, there are no studies available on sun-exposure habits among different countries. We conducted a cross-sectional survey among medical students from the University of Rome, Italy and the University of Granada, Spain to compare their photoprotection knowledge, habits, and attitudes. A total of 215 medical students (114 Spanish, and 101 Italian) were included. Spanish students considered the Sun to be the main cause of skin cancer (83.3% vs 61.4%, P=.003) and they looked at their skin more often than Italian students did (32.5% vs 9.9%, P <.001). The latter received information on photoprotection mainly from their dermatologist (34.7%, 35/101) vs Spaniards who received such information from their university (39.5%, 45/114; P <.001). After studying dermatology, Spaniards used sunscreen more frequently than Italians did (76.8% before vs 88.1% after; P=.007), and recognised the need to implement other measures as well (44.9% vs 67.2%; P=.025).

Impact of COVID-19 Pandemic on Cutaneous Squamous Cell Carcinoma: A Single-Centre Study of Epidemiologic, Clinic and Histopathological Factors. / [Artículo traducido] Impacto de la pandemia COVID-19 en el carcinoma de células escamosas cutáneo: un estudio unicéntrico de los factores epidemiológicos, clínicos e histopatológicos.

BACKGROUND: The COVID-19 pandemic may have adversely affected the early diagnosis of skin cancer. OBJECTIVE: To compare epidemiological, clinical and histopathological characteristics in patients undergoing cutaneous squamous cell carcinoma (SCC) surgery before and after the beginning of the pandemic. MATERIAL & METHODS: We conducted a cross-sectional study including two case series: (1) patients operated on for SCC in the year after the first state of alarm in Spain (15 March 2020), and (2) patients with SCC operated on in the previous year. Epidemiological, clinical and histopathological variables, tumour stage and risk grade were collected. RESULTS: 248 patients were included (127 undergoing surgery before the pandemic and 121 after the pandemic). After the beginning of the pandemic, the percentage of high-risk SCC significantly increased from 35.3% to 46.2% (p=0.011). However, no significant differences were found in thickness, perineural invasion or metastases. CONCLUSIONS: Although there has not been a significant reduction in the number of SCC operated on after the pandemic, there has been a significant increase in high-risk SCC. All this could lead to an increase in skin cancer mortality in the future.

[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.

Nonvenereal Infections in Spanish Dermatology Clinics: Results of the DIADERM Study. / Enfermedades infecciosas no venéreas atendidas en consultas de Dermatología en España: resultados del estudio DIADERM.

BACKGROUND AND OBJECTIVE: The burden of nonvenereal infections in Spanish dermatology practice has not yet been evaluated. The aim of this study was to analyze the overall weight of these infections in outpatient dermatology caseloads. MATERIAL AND METHODS: Observational cross-sectional study of diagnoses made by a random selection of dermatologists from the Spanish Association of Dermatology and Venereology (AEDV) working in outpatient dermatology clinics. The data were obtained through the anonymous DIADERM survey. Diagnoses of infectious diseases were selected using codes from the International Classification of Diseases, Tenth Revision. After excluding sexually transmitted infections, the diagnoses were classified into 22 groups. RESULTS: Spanish dermatologists diagnosed an estimated 16190 (95% CI, 9338-23042) nonvenereal infections on average per week, a figure that accounted for 9.33% of the dermatology caseload. The most common diagnostic groups were nonanogenital viral warts (7475 diagnoses, 46.17% of nonvenereal infections), dermatophytosis (3336, 20.61%), and other viral infections (1592, 9.84%), which included Molluscum contagiosum infections. Nonvenereal infections were more common than noninfectious dermatologic conditions in private clinics (P<.0020) and adults (P<.00001). Patients with these infections were also more likely to be discharged than those with other conditions in both public (P<.0004) and private (P<.0002) practices. CONCLUSIONS: Nonvenereal infections are frequent in dermatology. They are the third most common reason for outpatient visits, behind actinic keratosis and nonmelanoma skin cancer. By enhancing the participation of dermatologists in the management of skin infections and encouraging interactions with other specialists, we will be able to carve out a niche in an area we have scarcely ventured into to date.

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.

Selection of Quality Indicators for the Certification of Dermato-Oncology 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 dermato-oncología.

Quality indicators are crucial for standardizing and guaranteeing the quality of health care practices. The Spanish Academy of Dermatology and Venereology (AEDV) launched the CUDERMA Project to define quality indicators for the certification of specialized units in dermatology; the first 2areas selected were psoriasis and dermato-oncology. The aim of this study was to achieve consensus on what should be evaluated by these indicators using a structured process comprising a literature review and selection of an initial list of indicators to be evaluated in a Delphi consensus study following review by a multidisciplinary group of experts. The selected indicators were evaluated by a panel of 28 dermatologists and classified as either «essential¼ or «of excellence¼. The panel agreed on 84 indicators, which will be standardized and used to develop the certification standard for dermato-oncology units.

Dermatology Care in Spanish Public Hospitals: A Mapping Study of Health Care Resources and Medical and Surgical Activity in Dermatology Departments in 2019. / Mapa asistencial dermatológico: descripción de los recursos estructurales y de la actividad médico-quirúrgica de los servicios de dermatología de los hospitales públicos españoles en 2019.

BACKGROUND AND OBJECTIVE: No recent data on health care resources and medical and surgical activity in Spanish dermatology departments are available in the literature. The aim of this study was to compile this information for 2019. MATERIAL AND METHODS: Cross-sectional study based on an online survey sent to the heads of dermatology departments at public hospitals in Spain. RESULTS: Of the 162 department heads contacted, 59 answered the survey (participation rate, 36.4%). General findings included a shortage of staff, especially dermatologists, in hospitals of low and medium complexity. The main reason given for the shortage of dermatologists was a lack of interested applicants. Large hospital complexes had more infrastructure and equipment. Over 50% of the departments surveyed used a combination of in-person and virtual visits. Psoriasis units were the most common specialized care units. Approximately 75% of the hospitals had operating rooms with an anesthetist. More complex procedures such as sentinel lymph node biopsy and Mohs micrographic surgery were performed more often in large hospital complexes. Hospitalization and the presence of dermatology residents working call shifts were also more common in these hospitals. Teaching and research activity differed according to hospital complexity. CONCLUSIONS: We have mapped health care resource availability and medical and surgical activity in Spanish dermatology departments prior to the COVID-19 pandemic. Our findings could be useful for improving clinical management and defining future actions and areas for improvement.

Current State of Skin Cancer Prevention: A Systematic Review. / Situación actual de la prevención del cáncer de piel: una revisión sistemática.

Skin cancer deaths continue to rise despite the implementation of numerous preventive campaigns and programs. The aim of this systematic review was to evaluate reviews of primary and secondary skin cancer prevention strategies as reported over the past 10 years. We analyzed 63 systematic reviews and meta-analyses: 30 (46.6%) addressing primary interventions and 35 (55.6%) addressing secondary interventions. Two of the reviews covered both. The most widely reported primary prevention approaches were education programs (63.3%), followed by risk modeling to identify individuals at high risk for melanoma (17.6%), and the promotion of sunscreen use (11.8%). The most widely reported secondary prevention measures concerned imaging systems for early skin cancer detection (40%), smartphones and new technologies (22.9%), and visual diagnosis in population-based screening (17.4%). The most effective measures were primary prevention education programs to improve sun protection habits.

What Proportion of the Spanish Dermatology Caseload Corresponds to Primarily Sexually Transmitted Infections and Other Anogenital Dermatoses? Results From the DIADERM National Random Survey. / ¿Cuánta carga asistencial suponen las infecciones de transmisión predominantemente sexual y otras dermatosis anogenitales en las consultas de Dermatología en España? Resultados del muestreo aleatorio nacional DIADERM.

BACKGROUND AND OBJECTIVE: Predominantly sexually transmitted infections (STIs) and infestations and other anogenital dermatoses are covered in the training of specialists in dermatology and venereology in Spain. This study aimed to analyze the proportion of the dermatology caseload these diseases account for within the public and private dermatological activity of the Spanish health system. MATERIAL AND METHODS: Observational cross-sectional study of time periods describing the diagnoses made in outpatient dermatology clinics, obtained through the anonymous DIADERM survey of a representative random sample of dermatologists. Based on diagnostic codes of the International Classification of Diseases, Tenth Revision, 36 related diagnoses were selected, and classified into 12 groups. RESULTS: Only 3.16% of diagnoses corresponded to STIs and other anogenital dermatoses. The most common diagnostic group was anogenital human papillomavirus infection, followed by molluscum contagiosum, and inflammatory anogenital dermatoses. Lesions with these diagnoses were usually the main reasons for first visits in the National Health Service. In private practice, the diagnoses usually came after referrals from other physicians. CONCLUSIONS: STIs and other anogenital dermatoses account for a very small proportion of the dermatology caseload in Spain, although the inclusion of molluscum contagiosum diagnoses overestimates these conditions. The fact that no STI centers or monographic STI consultations were included in the random sample of dermatology partly explains the under-representation of these areas of the specialty. A determined effort to support and promote monographic STI centres and clinics should be made.

Photoprotection habits, attitudes and knowledge among school communities in the Costa del sol (Spain).

BACKGROUND: Scholar photoprotection campaigns are among the most effective strategies for preventing skin cancer. Analysis of the target population constitutes a valuable starting point for the implementation of primary prevention strategies. Our aim is to study photoprotection habits, attitudes and knowledge among a Spanish school community. METHODS: Descriptive cross-sectional study targeting schoolchildren, parents and teachers at 20 schools in the area of the Costa del Sol Health Agency in southern Spain. Two population-specific, validated questionnaires were used: the CHRESI (for children aged 0-10 years) and CHACES Questionnaire(for adults and adolescents aged > 11 years). We collected demographic data, skin colour, skin phototype, sunburn episodes, sun exposure and photoprotection practices, attitudes and knowledge. RESULTS: 1728 questionnaires were analyzed (22% parents, 14.5% teachers, 44.8% adolescents and 18.6% children). The average ages were 8 years (children), 16 years (adolescents), 39 years (teachers) and 42 years (parents). Globally, the predominant features were: male sex (52%), Spanish nationality (92%) and phototypes II-III (61%). Children, followed by adolescents, reported the highest exposure to the sun, both in frequency and in duration. Adolescents had the higher rate of sunburn (75%), followed by parents/teachers (54.1%) and children (44.1%). Children and their parents were the most likely to adopt photoprotection measures, while adolescents presented more risky attitudes. Knowledge regarding photoprotection was acceptable (6.9/10). CONCLUSIONS: This study highlights the need to improve photoprotection knowledge, habits and attitudes among our target population. Scholars, parents and teachers in our area should be addressed in campaigns to promote healthy sun exposure habits, thus reducing skin cancer-related morbidity and mortality in this region.

What Proportion of the Caseload at Dermatology Outpatient Clinics in Spain Do Skin Tumors Account for? Results from the DIADERM National Random Sampling Project. / ¿Cuánta carga asistencial supone la enfermedad tumoral cutánea en la actividad ambulatoria en la Dermatología española? Resultados del muestreo aleatorio nacional DIADERM.

INTRODUCTION AND OBJECTIVE: A significant part of a dermatologist's activity involves the diagnosis and management of tumors. The aim of this study was to analyze the caseload at public and private dermatology outpatient clinics in Spain to determine the proportion of tumor diagnoses. MATERIAL AND METHOD: Observational cross-sectional study of diagnoses made in dermatology outpatient clinics during 2 data-collection periods in the DIADERM study, an anonymous survey of a random, representative sample of dermatologists across Spain. Diagnoses made during the 2 periods were coded according to the CIE-10. There were 165 tumor-related codes, classified into 24 groups. For the purpose of this study, these groups were then reduced to benign melanocytic lesions, malignant melanocytic lesions, benign nonmelanocytic lesions, and malignant nonmelanocytic lesions. RESULTS: Tumors accounted for 46.2% of all diagnoses; 18.5% of the tumors were malignant (a category that included in situ forms of keratinocyte cancers). Four of the 10 most common diagnoses were of malignant tumors: in situ keratinocyte cancers, basal cell carcinoma, melanoma, and squamous cell carcinoma. Significant differences were observed between malignant and benign tumors according to type of practice (public vs. private) and geographic region. CONCLUSION: Skin cancer accounts for a significant part of the dermatologist's caseload in Spain. Differences can be observed depending on the public/private healthcare setting and other factors.

Validation of a Questionnaire Designed to Study Knowledge, Attitudes, and Habits Related to Sun Exposure Among Young Adults: The CHACES Questionnaire. / Validación de un cuestionario para el estudio sobre hábitos, actitudes y conocimientos en fotoprotección en la población adultojuvenil: «cuestionario CHACES¼.

Skin cancer prevention campaigns in schools have been shown to be both effective and cost-effective. The success of such programs depends on the use of an appropriate design informed by a prior survey of the target population (pupils, teachers, and parents). There are, however, very few validated Spanish-language questionnaires designed to study the habits and knowledge of this population with respect to sun exposure in childhood and none designed for use with a young adult population. OBJECTIVES: To construct and validate a questionnaire designed to explore sun exposure behaviors in a young adult population. METHODOLOGY: Two questionnaires were developed, one for adults (18+) and the other for young adults (11-17); both included demographic information, skin color, Fitzpatrick skin type, and history of sunburn as well as questions on knowledge, attitudes and practices related to sun exposure. The content was then piloted and its validity analyzed. The subsequent validation study was divided into 2 phases as follows: 1) analysis of the validity and internal consistency of the items in a cross-sectional study of 1,482 adults and adolescents, using exploratory factor analysis to test construct validity and Cronbach α to measure internal consistency; and 2) evaluation of test-retest reliability in 39 individuals. RESULTS: The pilot study demonstrated the content validity of both questionnaires. Principal component analysis revealed that 2 components in each of the dimensions studied accounted for over 50% of the variance. A good correlation was found between the items studied. Validity was demonstrated in the first phase of the analysis with a Cronbach α of between 0.45 and 0.8 for all components except knowledge (0.335). In the second phase, test-retest reliability was demonstrated (absolute agreement>60%). CONCLUSIONS: The psychometric properties of the questionnaire make it a valid and reliable tool for the study of knowledge, attitudes, and habits with respect to sun exposure in the young adult school population.

Pre-operative ultrasound planning in the surgical management of patients with hidradenitis suppurativa.

BACKGROUND: Ultrasonography can improve disease severity assessment in hidradenitis suppurativa (HS) patients. The use of pre-operative ultrasonography could improve surgical outcomes in HS patients. OBJECTIVES: (i) To assess changes in the projected skin-excised area after the use of pre-operative ultrasonography, (ii) to explore the clinical factors potentially associated with inaccurate clinical surgical delimitation and (iii) to compare recurrence rates after pre-operative ultrasound vs clinical surgical margin delimitation at week 24. METHODS: Cohort study. Patient candidates for surgical treatment by wide excision and healing by secondary intention with a clinical projected skin-excised area equal to or larger than 15 cm2 were included. The main variables of interest were the clinical and ultrasound projected skin-excised area and surgical recurrence. RESULTS: Pre-operative ultrasound surgical margin delimitation increased the mean excised area by 3.67 (SD 0.86) cm2 , P = 0.004. The Bland-Altman plot showed that in 65% of surgical procedures the use of ultrasonography increased the projected skin-excised area. Higher IHS4 scores, BMI, male sex and Hurley stage II vs III all increased the difference between clinical and ultrasound surgical delimitation. At week 24, the recurrence rate in the surgical clinical delimitation cohort was 30% compared to 10% in the cohort with pre-operative ultrasonography (P = 0.10). CONCLUSIONS: Pre-operative ultrasonography improves surgical margin delimitation and can lower recurrence rates at 24 weeks in HS patients. Potential risk factors for inaccurate clinical surgical delimitation are obesity, male sex, Hurley II stage and elevated IHS4 scores, so special attention should be given to these patients when ultrasonography is not available and surgical delimitation is based only on clinical examination.

Proportion of Potentially Avoidable Referrals From Primary Care to Dermatologists for Cystic Lesions or Benign Neoplasms in Spain: Analysis of Data From the DIADERM Study. / Análisis de la proporción de derivaciones potencialmente evitables desde Atención Primaria a Dermatología por lesiones quísticas o tumorales benignas en España. Datos del estudio DIADERM.

BACKGROUND AND OBJECTIVE: Skin lesions are a common reason for consulting a primary care physician. Current legislation in Spain states that purely aesthetic skin problems that do not pose a health problem are not to be treated within the National Health Service. The aim of this study was to estimate the proportion of referrals from primary care physicians to dermatologists that were for cystic lesions or benign tumors and could potentially have been avoided. MATERIAL AND METHODS: We consulted cases registered in the DIADERM study dataset, which is representative of dermatology practice in Spain, and collected the main diagnoses given on referring patients from primary care. A referral diagnosis was classified as potentially avoidable if it corresponded to one of the primary care discharge diagnoses listed in a consensus paper of the Andalusian section of the Spanish Academy of Dermatology and Venereology (AEDV). RESULTS: We collected 2171 main reasons for first-visit referrals to dermatologists; 686 of them (31.6%) were for cystic lesions or benign tumors and classified as potentially avoidable. In 478 cases (22%) the patients were discharged on the first visit. The most frequent diagnoses in such cases were seborrheic keratosis (9.3%) and melanocytic nevus (8.6%). CONCLUSIONS: Nearly a third of referrals from primary care to a dermatologist were for cystic lesions and benign tumors and could have been avoided. A clearer understanding of our caseload can be useful for improving planning, training, and health care system management.

Do Dermatologic Diagnosis Change in Hot vs. Cold Periods of The Year? A Sub-Analysis of the DIADERM National Sample (Spain 2016). / ¿Existe variación en los diagnósticos dermatológicos entre la temporada de frío vs. calor? Un subanálisis del estudio DIADERM (España 2016).

BACKGROUND: Knowledge of seasonal variation of cutaneous disorder may be useful for heath planning and disease management. To date, however, descriptions of seasonality including all diagnoses in a representative country sample are very scarce. OBJECTIVES: To evaluate if clinical dermatologic diagnosis in Spain change in the hot vs. cold periods. MATERIALS AND METHODS: Survey based on a random sample of dermatologists in Spain, stratified by area. Each participant collected data during 6 days of clinical activity in 2016 (3 in the cold period of the year, 3 in the hot period). Clinical diagnoses were coded using ICD-10. RESULTS: With a 62% response proportion, we got data on 10999 clinical diagnoses. ICD-10 diagnostic groups that showed changes were: other benign neoplasms of skin (D23), rosacea (L71) and other follicular disorders (L73), which were more common in the hot period and acne (L70) which was more frequent in the cold period. We describe differences in the paediatric population and in private vs. public practice. Some of these differences might be associated to differences in the population demanding consultations in different periods. CONCLUSIONS: The frequency of most clinical diagnosis made by dermatologists does not change over the year. Just a few of the clinical diagnoses made by dermatologists show a variation in hot vs. cold periods. These variations could be due to the diseases themselves or to seasonal changes in the demand for consultation.
