Prevalencia de sensibilización a hongos en pacientes con alergia respiratoria

Como parte de la etiología de la alergia respiratoria esta la genética, los factores prenatales y la sensibilidad a diversos aeroalérgenos, entre estos los hongos

Calidad de vida en urticaria crónica y su relación con el impacto económico y control de la enfermedad en pacientes atendidos en el Hospital Universitario de Monterrey, México

Abstract Background: Chronic urticaria (CU) manifests itself with hives and sometimes angioedema. Physical and social discomfort worsens patient quality of life. CU has an important impact on patients’ economy. Objective: To evaluate the relationship of quality of life (QoL) with economic burden and chronic urticaria control of in patients treated at our center. Methods: Cross-sectional, descriptive, observational study. We included CU-diagnosed adult patients. The CU-Q2oL and UCT questionnaires in Spanish and the economic burden and comorbidities questionnaire developed by our center were applied. A sample size of 36 patients was calculated. Results: 36 patients were included, out of which 58.3% were females. Mean age was 39.9 ± 15.6 years. Regarding QoL, 66.7% of patients reported being "A little" aff ected, 25% "Somewhat" and 8.3% "A lot", and its relationship with monthly income yielded a p-value of 0.017. 38.9% of patients reported having a monthly income of less than $ 5000 pesos. When disease control was compared with the CU-Q2oL, a signifi cant diff erence was obtained for questions concerning itching. Conclusion: There was association between the quality of life of patients with chronic urticaria and monthly income, the lower the income, the more will the quality of life be aff ected. Furthermore, greater CU control was observed to reduce the negative eff ects on quality of life caused by itching

Reactividad cruzada en sinusitis alérgica fúngica. Reporte de caso

La presencia de mucina alérgica en la rinosinusitis alérgica fúngica (RAF) es una manifestación que la identifica como un proceso de hipersensibilidad. En la RAF existe un fenómeno de reactividad cruzada entre proteínas unidas a IgE que tienen al menos dos epítopes compartidos. ABSTRACT The presence of allergic mucin in allergic fungal sinusitis (AFS) is a manifestation that identifies it as a hypersensitivity process. AFS has a phenomenon of cross-reactivity to IgEbound proteins having at least two shared epitopes

Métodos y técnicas de monitoreo y predicción temprana en los escenarios de riesgos socionaturales

Esta obra concentra los métodos y las técnicas fundamentales para el seguimiento y monitoreo de las dinámicas de los escenarios de riesgos socionaturales (geológicos e hidrometeorológicos) y tiene como objetivo general orientar, apoyar y acompañar a los directivos y operativos de protección civil en aterrizar las acciones y políticas públicas enfocadas a la gestión del riesgo local de desastre

Prevalence of sensitization to fungi in patients with respiratory allergy

Background: As part of the etiology of respiratory allergy we have genetics, prenatal factors and sensitivity to various airborne allergens, between these fungi are found. Relationship has been found between sensitization to fungal in skin tests and allergy pathogenesis and aggravation. There is a few literature in Mexico and in the north of the country it is lacking regarding this problem. Objective: Assess the prevalence of sensitization to fungi in patients with respiratory allergy in skin tests to airborne allergens; determine the most prevalent fungus and prevalence of sensitization to each species of fungus per year, to assess the prevalence of sensitization to fungi by years. Material and method: Cross-sectional, observational and descriptive study conducted from 1 January 2010 to 31 December 2014 in patients treated at the Regional Center of Allergy and Clinical Immunology (Monterrey, Mexico) where we reviewed a database with patients whom performed skin tests, sensitization to 6 species of fungi were evaluated. We performed tables of data capture and statistical analysis. Results: 4880 patients had respiratory allergy, a 17.1% prevalence of sensitization to fungal skin tests was determined. The fungus specie most prevalent was Alternaria alternata with 5.5%. The year range with the highest prevalence of sensitization was 0-10 years with a 6.7% Conclusion: The prevalence of fungi sensitization was higher than the global prevalence found, but lower than the prevalence found in other researches in Mexico

Cross-reactivity in allergic fungal sinusitis. Case report

Background: The presence of allergic mucin in allergic fungal sinusitis (AFS) is a manifestation that identifies it as a hypersensitivity process. AFS has a phenomenon of cross-reactivity to IgE-bound proteins having at least two shared epitopes. Case report: A 13-year-old male with nasal obstructive symptoms of three years of evolution. An obstructive mass was identified in the sinuses through physical examination and CT. In endoscopic surgery, the left nostril polyp was identified with the macroscopic appearance of allergic mucin; the polyp was resected. Final histopathological examination using periodic acid-Schiff and Grocott’s methenamine silver staining indicated Aspergillus. Two weeks after surgery, percutaneous tests showed sensitization to Alternaria, Helminthosporium sativum, and Deramatophagoides farianae with negativity to Aspergillus fumigatus. Conclusions: The absence of significant titers of specific IgE antibodies to Aspergillus fumigatus was the evidence that the hypersensitivity response was triggered by a pathogen other than that isolated in histopathological study, which coupled with positive tests for other fungi may be explained by the cross-reactivity phenomenon in a phenomenon of likely hypersensitivity

3er. Coloquio: Fortalecimiento de los Colectivos de Docencia

Las memorias del 3er. Coloquio de Fortalecimiento de Colectivos de Docencia deben ser entendidas como un esfuerzo colectivo de la comunidad de académicos de la División de Ciencias y Artes para el Diseño, en medio de la pandemia COVID-19, con el fin de: • Analizar y proponer acciones concretas que promuevan el mejoramiento de la calidad docente en la División. • Proponer acciones que permitan continuar fortaleciendo los cursos con modalidad a distancia (remotos). • Ante un escenario que probablemente demandará en el mediano plazo, transitar del modelo remoto a un modelo híbrido, proponer acciones a considerar para la transición de los cursos. • Planear y preparar cursos de nivelación de conocimientos, para cuando se transite a la impartición de la docencia de manera mixta o presencial, dirigidos a los alumnos que no hayan tenido oportunidad de desarrollar actividades relevantes para su formación, como prácticas de talleres y laboratorios, visitas, o alguna otra actividad relevante
