ICON: Diagnosis and management of allergic conjunctivitis. Authors: Bielory L1, Delgado L2, Katelaris CH3, Leonardi A4, Rosario N5, Vichyanoud P6. Author information Abstract Ocular allergy (OA), interchangeably known as allergic conjunctivitis, is a common immunological hypersensitivity disorder affecting up to 40% of the population. Ocular allergy has been increasing in frequency, with symptoms of itching, redness, and swelling that significantly impacts an individual's quality of life (QOL). Ocular allergy is an often underdiagnosed and undertreated health problem, because only 10% of patients with OA symptoms seek medical attention, whereas most patients manage with over-the-counter medications and complementary nonpharmacological remedies. The clinical course, duration, severity, and co-morbidities are varied and depend, in part, on the specific ocular tissues that are affected and on immunologic mechanism(s) involved, both local and systemic. It is frequently associat...

 Instructivo para la vigilancia en salud pública intensificada de infección respiratoria aguda asociada al nuevo coronavirus 2019 (COVID-19).  Fecha de actualización: viernes 20 de marzo 2020 Versión: 7 1. Introducción El 31 de diciembre de 2019 la Comisión Municipal de Salud y Sanidad de Wuhan (provincia de Hubei, China) informó sobre un agrupamiento de 27 casos de neumonía de etiología desconocida con inicio de síntomas el 8 de diciembre; los casos reportaban antecedente de exposición común a un mercado de mariscos, pescados y animales vivos en la ciudad de Wuhan. El 7 de enero de 2020, las autoridades chinas identificaron como agente causante del brote un nuevo tipo de virus de la familia Coronaviridae, que fue denominado “nuevo coronavirus”, SARS-COV-2 (1). Dado que los casos de coronavirus suelen causar síntomas respiratorios, la Organización Mundial de la Salud (OMS) ha emitido recomendaciones de protec...

BCG Vaccination Enhances the Immunogenicity of Subsequent Influenza Vaccination in Healthy Volunteers: A Randomized, Placebo-Controlled Pilot Study. Martes 14 de abril

BCG Vaccination Enhances the Immunogenicity of Subsequent Influenza Vaccination in Healthy Volunteers: A Randomized, Placebo-Controlled Pilot Study Authors: Jenneke Leentjens 1, Matthijs Kox 2, Robin Stokman 2, Jelle Gerretsen 2, Dimitri A Diavatopoulos 3, Reinout van Crevel 4, Guus F Rimmelzwaan 5, Peter Pickkers 2, Mihai G Netea 4 Abstract Background: Influenza-related morbidity and mortality remain high. Seasonal vaccination is the backbone of influenza management but does not always result in protective antibody titers. Nonspecific effects of BCG vaccination related to enhanced function of myeloid antigen-presenting cells have been reported. We hypothesized that BCG vaccination could also enhance immune responses to influenza vaccination. Methods: Healthy volunteers received either live attenuated BCG vaccine (n = 20) or placebo (n = 20) in a randomized fashion, followed by intramuscular injection of trivalent influenza vaccine 14 days later. Hemagglutination-inhibiting (H...
