Allergenic profile of Quercus rotundifolia pollen in Alentejo, Portugal
Antunes, Célia M.; Candeias, Joana; Anacleto, Sara; Arriegas, Rute; Calhau, Isabel; Costa, Ana R.; Brandão, Rui; Lopes, LuísaBackground and Aim: Grasses and olive are the most relevant allergenic species in the Alentejo region. However, aggravation of allergic symptoms has been reported in the early spring, before grass and olive pollen seasons. Quercus pollen is the most abundant pollen type in the early spring in Alentejo, nonetheless its allergen profile has not yet been evaluated. The aim of this work was to characterize the alle...

Semedo, Diogo; Ladeiro, Filipa; Ruivo, Mariana; Oliveira, Carlos; Sousa, Filipa de; Gayo, Mariana; Lima, Clara; Magalhães, Frederico; Brandão, RuiIntroduction: Though typically found in adolescents, acne frequently affects the adult population. In Portugal, no representative studies about acne prevalence in greater populational areas are known. This study had the following objectives: calculate acne prevalence in primary healthcare patients; its characteristics, including risk factors for onset and worsening; collect information concerning self-medicatio...

Análise das concentrações de pólen de gramíneas na atmosfera de Portugal Contin...
Caeiro, Elsa; Camacho, Irene Câmara; Lopes, Luísa; Gaspar, Ângela; Todo-Bom, Ana; Oliveira, José Ferraz de; Trindade, José Costa; Brandão, RuiIntrodução: A exposição ao pólen atmosférico da família das Poaceae constitui a principal causa de polinose em Portugal. Objectivos: Analisar e comparar a estação de pólen atmosférico principal (EPAP) do pólen de gramíneas das estações de monitorização continentais da Rede Portuguesa de Aerobiologia: Porto, Coimbra, Lisboa, Évora e Portimão. Métodos: No estudo utilizaram -se os dados diários de 7 anos (2002 -20...
Quantificação de Aeroalergénios de Gramíneas por Imunoensaios com Phl p5
Antunes, Célia M.; Brandão, Rui; Martins, Rosário; Caldeira, Ana; Munhoz, W.O pólen das gramíneas constitui seguramente uma das principais fontes de aeroalergenos atmosféricos a nível europeu, nomeadamente em Portugal. O nível de exposição a este agente é actualmente calculado a partir de contagens polínicas, efectuadas em amostras de ar atmosférico.
Comparação entre a concentração atmosférica de Phl p5 e as contagens polínicas ...
Antunes, Célia M.; Munhoz, W.; Martins, Rosário; Caldeira, Ana; Caeiro, E.; Lopes, L.; Brandão, RuiA exposição a alergenos de gramíneas é actualmente calculada a partir de contagens polínicas dos respectivos tipos polínicos, efectuadas em amostras de ar atmosférico segundo uma metodologia normalizada e assente em equipamentos tipo HIRST. Não existe ainda suficiente evidência de que tais contagens representem uma boa estimativa da exposição aos aeroalergenos deste tipo polínico pelo que, neste estudo, se proc...

Munhoz, V.W.; Martins, Rosário; Caldeira, Ana Teresa; Antunes, Célia M.; Caeiro, E.; Carvalho, E.; Brandão, RuiAirborne pollen of grasses (Poaceae family) is the main aeroallergen in many european countries, namely in Portugal. Grasses includes many herbaceous species with an anemophyllous pollination.

Antunes, Célia M.; Caldeira, Ana. T.; Martins, M. Rosário; Munhoz, V.W.; Thibaudon, M.; Carvalho, E.; Brandão, RuiCurrently allergen exposure is estimated from pollen counts in air samples. However, there is not yet enough evidence to establish this technique as a reliable indicator of allergen exposure. Presently, there are a few reliable and sensitive ELISA methods that allow allergen quantification in environmental air samples but none is known to quantify Poaceae allergens. The aim of this work was to develop a novel a...
