RESUMEN
BACKGROUND: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports. OBJECTIVES: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak. METHODS: We conducted a prospective cross-sectional study in multiple medical facilities in Spain to describe the cases of monkeypox in the 2022 outbreak. RESULTS: In total, 185 patients were included. Most cases started with primarily localized homogeneous papules, not pustules, in the probable area of inoculation, which could be cutaneous or mucous, including single lesions. Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common lesions included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Four patients were hospitalized, none died. Smallpox vaccination and well-controlled HIV disease were not associated with markers of severity. Contact during sex is the most likely mechanism of transmission. In this outbreak, cases have been described in men who have sex with men and are strongly associated with high-risk sexual behaviours. Seventy-six per cent of the patients had other sexually transmitted diseases upon screening. CONCLUSIONS: The clinical findings in this outbreak differ from previous findings and highly suggest contact transmission and initiation at the entry site. The characterization of the epidemiology of this outbreak has implications for control. What is already known about this topic? Monkeypox eruption is described as consisting of pustules. The roles of HIV and previous smallpox vaccination in the prognosis are unknown. The transmission route was initially described as respiratory droplets and was later suggested to be via sexual contact. What does this study add? Initial lesions at the probable inoculation area were homogeneous and papular (pseudopustules). Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common signs included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Well-controlled HIV and previous smallpox vaccination were not associated with severity. No patient died. The data support the hypothesis of transmission via contact during sex. Although this might change, the outbreak is currently limited mostly to men who have sex with men, with high-risk factors for sexually transmitted diseases.

INTRODUCTION: Skin melanoma incidence has risen in the last decades becoming a major public health problem in many regions of the world. Geographic variation of rates is not well understood. PURPOSE: To assess the spatial distribution of skin melanoma in Gran Canaria Island (Canary Islands, Spain) and to evaluate the role of environmental, socio-economic, and demographic factors in this distribution. METHODS: We performed a small-area study with disease mapping at the census-tract level (CT) in Gran Canaria between 2007 and 2018. After testing for spatial autocorrelation, we integrated individual-level health data with census-based demographic and socio-economic indicators, and satellite-based environmental data. Finally, we assessed the role of demographic, socio-economic and environmental factors on skin melanoma incidence using a Bayesian analytical framework, with options for non-spatial and spatial random effects. RESULTS: 1058 patients were diagnosed with invasive skin melanoma in the study period and geolocated to a CT (number of CT in Gran Canaria = 565). We found evidence of global spatial autocorrelation in skin melanoma incidence (Moran's I = 0.09, pseudo p-value = 0.001). A few hotspots were detected, fundamentally in urban northern tracts. A radial pattern of high values was also observed in selected ravines with historical isolation. Multivariable conditional autoregressive models identified urbanicity, percent of females, and a high socio-economic status as risk factors for disease. Solar radiation did not show a significant role. CONCLUSION: Urbanicity and a high socio-economic status were identified as the main risk factors for skin melanoma. These associations might reflect differential melanoma susceptibilities or be explained by health inequalities in detection. This study also uncovered high-risk areas in particular ravines. Future targeted research in these regions might help better understand the role of genetic and toxic factors in melanoma pathogenesis.

BACKGROUND: Guidelines and expert recommendations on infantile hemangiomas (IH) are aimed at increasing homogeneity in clinical decisions based on the risk of sequelae. OBJECTIVE: The objective was to analyze the inter- and intra-observer agreement among pediatric dermatologists in the choice of treatment for IH. METHODS: We performed a cross-sectional inter-rater and intra-rater agreement study within the Spanish infantile hemangioma registry. Twenty-seven pediatric dermatologists were invited to participate in a survey with 50 clinical vignettes randomly selected within the registry. Each vignette contained a picture of an infantile hemangioma with a clinical description. Raters chose therapy among observation, topical timolol, or oral propranolol. The same survey reordered was completed 1 month later to assess intra-rater agreement. Vignettes were stratified into hemangioma risk categories following the Spanish consensus on IH. The agreement was measured using kappa statistics appropriate for the type of data (Gwet's AC1 coefficient and Gwet's paired t test). RESULTS: Twenty-four dermatologists completed the survey. Vignettes represented 7.8% of the Spanish hemangioma registry. The inter-rater agreement on the treatment decision was fair (AC1 = 0.39, 95% confidence interval [CI]: 0.30-0.47). When stratified by risk category, good agreement was reached for high-risk hemangiomas (AC1 = 0.77, 95% CI: 0.51-1.00), whereas for intermediate- and low-risk categories, the agreement was only fair (AC1 0.31, 95% CI: 0.16-0.46 and AC1 = 0.38, 95% CI: 0.27-0.48, respectively). Propranolol was the main option for high-risk hemangiomas (86.4%), timolol for intermediate-risk (36.8%), and observation for low-risk ones (55.9%). The intra-rater agreement was good. The inter-rater agreement between pediatric dermatologists on the treatment of IH is only fair. Variability was most significant with intermediate- and low-risk hemangiomas.

BACKGROUND: The Canary Islands are a leading European touristic destination. The ultraviolet index (UVI) in the region is the highest in Spain, and similar to indexes registered in Australia and New Zealand, which hold the highest incidence of skin melanoma worldwide. Yet according to cancer registry data, the incidence in the Canary Islands in the late 1990s was the lowest in Spain (among the lowest in Europe) and about six times lower than in New Zealand. PURPOSE: To analyze the incidence rates of skin melanoma in Gran Canaria island between 2007 and 2018. METHODS: The study was based in the two centres of the Canary Islands' Healthcare Service centralizing melanoma care in Gran Canaria. We analyzed crude and age-standardized (ASR) incidence rates of invasive cutaneous melanoma for the period 2007-2018 following the inclusion criteria of the International Agency for Research on Cancer (IARC). Clinical and histological characteristics of melanoma patients were assessed. RESULTS: A total of 1058 patients were included. The incidence rates obtained matched the latest available Canary Islands' cancer registry data, confirming its reliability (ASR, Segi-Doll world standard population: 6.4 cases per 100,000 habitants for 2008-2012). The incidence was also below the latest IARC predictions for Southern Europe (GLOBOCAN 2018). Histological characteristics of patients were similar to other Southern European series. CONCLUSIONS: The incidence of skin melanoma in Gran Canaria is unexpectedly low for a Southern European population exposed to such a high UVI. Further research in the Canary Islands could provide insight into a better understanding of melanoma pathogenesis.

BACKGROUND: An early diagnosis of cutaneous melanoma remains determinant for improved survival. Low educational attainment has been associated with a late-stage diagnosis in settings where access to healthcare is restricted. Little evidence is available from regions with universal healthcare. We aimed at analysing whether educational attainment was associated with Breslow thickness at diagnosis in a peripheral European region with universal healthcare (in the Canary Islands, Spain). METHODS: We conducted a cross-sectional study with prospectively collected data (2010-2017). Patients were recruited at diagnosis, and information about Breslow thickness, age at diagnosis, gender, highest educational attainment and site of melanoma were registered. Univariate and multivariate linear regression analyses were performed. RESULTS: Low educational attainment was associated with thicker tumours at diagnosis. The association remained true after adjustment for age, gender and site of melanoma. In the multivariate analysis, tumours diagnosed in patients with low educational attainment were on average 1.08â¯mm thicker (95% confidence interval: 0.36-1.81; pâ¯=â¯0.003) than those diagnosed in patients with high educational attainment. CONCLUSION: Public health strategies targeting this vulnerable group are currently needed in the Canary Islands (Spain).

BACKGROUND: Methotrexate (MTX), a traditional antipsoriatic drug, is very frequently used either as monotherapy or in combination with other systemic drugs. OBJECTIVES: To assess the effectiveness and safety of MTX in psoriasis in usual clinical practice. METHODS: We conducted a retrospective study. We performed an electronic and manual chart review of patients treated with MTX in the Psoriasis Unit of our Hospital from January 2007 to December 2014. Demographic and clinical data, PASI/DLQI scores and reasons for suspension of all patients treated with MTX in usual clinical practice were recorded. RESULTS: Two hundred and eighteen patients were included. MTX was administered in 67% of cases as the first systemic treatment. The average treatment duration was 17.2 ± 13.6 months. All patients were subjected to clinical and laboratory monitoring. About 33.5% of them achieved a reduction of 75% or more of the initial PASI at week 12, 34.9% at week16, 44.7% at week 24, and 52.8% at week 48. A 3.3% had to discontinue the therapy due to analytical hepatic (2.8%) or renal (0.5%) abnormalities. Only one patient experienced severe interstitial pneumonitis and none required liver biopsy. CONCLUSIONS: MTX is an effective and safe option for the treatment of psoriasis in the real-world clinical practice.
