Prurigo actínico en un centro dermatológico de referencia en Colombia: 108 casos

Introduction: Actinic prurigo is a chronic photodermatosis. It affects the Latin American population more frequently, predominantly women, and involves the sun-exposed areas of the skin, conjunctiva, and lips.Objective: To update the information on the clinical-epidemiological characteristics and treatment of patients with actinic prurigo in Colombia.Materials and methods: We conducted a cross-sectional study including the medical records of patients with actinic prurigo treated in the Photodermatology Service of Hospital Universitario Centro Dermatológico Federico Lleras Acosta between 2011 and 2016. We described the demographic, clinical, histopathological, and treatment characteristics of the patients.Results: We included 108 patients, 77 (71.3%) were women and 31 (28.7%) men, mainly with phototypes III-IV (70%). The disease had begun during the first decade of life in 66.4% of the cases and 25% of the patients had a family history with the condition. The lesions predominated on the face (93.5%), forearms (79.6%), and back of the hands (70.4%). Ocular (87.9%) and lip (88.8%) involvement was also documented. A photo-provocation test with UVA was performed in 25% of the cases and skin biopsies in 19.4%. Physical and chemical photoprotection was indicated in all patients. Mild to moderate cases were treated with topical corticosteroids (91.7%) and calcineurin inhibitors (65.7%) while severe cases received thalidomide (33.3%) and pentoxifylline (14.8%).Conclusion: The characteristics of actinic prurigo patients in Colombia are similar to those reported in other Latin American countries: early onset of the disease, predominance in women, frequent involvement of conjunctiva and lips, and adequate response to topical and systemic treatment.Introducción.

Las características de los pacientes colombianos con prurigo actínico son similares a las reportadas en otros países latinoamericanos: inicio temprano de la enfermedad, predominio en mujeres, compromiso frecuente de conjuntivas y labios, y adecuada respuesta al tratamiento tópico y sistémico

Multiteide Project: Multiparametric characterization of the activity of Teide-Pico Viejo volcanic system

European Geosciences Union General Assembly (2017. Viena)Teide-Pico Viejo complex stands for one of the major natural volcanic hazards in the Canary Islands, due to the expected types of eruptions in the area and the high number of inhabitants in Tenerife Island. Therefore, it is necessary to have a volcanic alert system able to afford a precise assessment of the current state of the complex. For this purpose, the knowledge of the expected signals at each volcanic activity level is required. Moreover, the external effects that can affect the measurements shall be distinguished, external influences as the atmosphere are qualitatively known but have not been quantified yetCentro Geofísico de Canarias, Instituto Geográfico Nacional, EspañaObservatorio Geofísico Central, Instituto Geográfico Nacional, EspañaInstituto Geológico y Minero de España, EspañaLaboratoire GéoSciences Réunion, Institut de Physique du Globe de Paris, Centre National de la Recherche Scientifique, EspañaPeer reviewe

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed

Spread of a SARS-CoV-2 variant through Europe in the summer of 2020

[EN] Following its emergence in late 2019, the spread of SARS-CoV-21,2 has been tracked by phylogenetic analysis of viral genome sequences in unprecedented detail3,4,5. Although the virus spread globally in early 2020 before borders closed, intercontinental travel has since been greatly reduced. However, travel within Europe resumed in the summer of 2020. Here we report on a SARS-CoV-2 variant, 20E (EU1), that was identified in Spain in early summer 2020 and subsequently spread across Europe. We find no evidence that this variant has increased transmissibility, but instead demonstrate how rising incidence in Spain, resumption of travel, and lack of effective screening and containment may explain the variant’s success. Despite travel restrictions, we estimate that 20E (EU1) was introduced hundreds of times to European countries by summertime travellers, which is likely to have undermined local efforts to minimize infection with SARS-CoV-2. Our results illustrate how a variant can rapidly become dominant even in the absence of a substantial transmission advantage in favourable epidemiological settings. Genomic surveillance is critical for understanding how travel can affect transmission of SARS-CoV-2, and thus for informing future containment strategies as travel resumes.S
