“…The data are consistent with previous investigations of thunderstorm asthma epidemics in London, Melbourne, and Tamworth [2,4,10]. Allergy to rye grass pollen and history of hayfever has been associated with thunderstorm asthma exacerbation in previous investigations [2,4,13]. This is consistent with the findings of the current study in which 95% of thunderstorm cases were allergic to rye grass and a similar proportion reported prior hayfever symptoms.…”

“…Asthma epidemics have been reported in association with thunderstorms in Melbourne (Australia) [2]; Tamworth (UK) [10] London (UK) [4,11,12] and Birmingham (UK) [13]. Several meteorological features such as temperature, high humidity, rainfall, thunderstorm electric or lightening activity have been proposed as possible triggers for severe exacerbations of asthma following a thunderstorm [4,11], However, not all thunderstorms are associated with asthma exacerbations and not all asthma epidemics are preceded by thunderstorms [14].…”

The aim of the study was to characterize patients at risk of asthma exacerbation during spring thunderstorms and identify potential measures to ameliorate the impact of those events.A case-control study was conducted among patients aged 7±60 yrs, who attended Wagga Hospital (NSW, Australia) for asthma during the period of 1 June 1997 to 31 October 1997. One hundred and eighty-three patients who attended on 30 and 31 October 1997 were the cases and the remaining 121 patients were the controls. Questionnaire data were obtained from 148 (81%) cases and 91 (75%) controls.One hundred and thirty-eight (95%) cases who attended during the thunderstorm gave a history of hayfever prior to the event compared to 66 (74%) controls who attended at other times (odds ratio (OR) 6.01, 95% confidence interval (CI) 2.55± 14.15); 111 (96%) cases were allergic to rye grass pollen compared to 47 (64%) controls (OR 23.6, 95% CI 6.6±84.3). Among subjects with a prior diagnosis of asthma (64% cases and 82% controls), controls (56%) were more likely to be taking inhaled steroids at time of the thunderstorm than cases (27%, OR 0.3, 95% CI 0.16±0.57).History of hayfever and allergy to rye grass are strong predictors for asthma exacerbation during thunderstorms in spring. The lower rate of inhaled steroid use in thunderstorm cases suggests that this treatment may be effective in preventing severe attacks during thunderstorms. Eur Respir J 2000; 16: 3±8.

“…However, slightly lower mean temperatures were, in fact, observed for Cork (15°C) compared to Worcester (16°C), at which points Didymella concentrations approached their maxima. Corden and Millington (1994) confirmed some previous findings of Packe and Ayres (1985) that a hot dry spell (20°C) before rainfall had a significant impact on further outbreaks of Didymella spores. This suggestion would also be in (Fig.…”

Atmospheric concentrations of Alternaria, Cladosporium, Ganoderma and Didymella spores monitored in Cork (Ireland) and Worcester (England) during the summer of 2010

This study represents the first international intercomparison of fungal spore observations since 1990, focusing on atmospheric concentrations of Alternaria, Cladosporium, Ganoderma and Didymella spores. The campaigns were performed at sites located in Cork (Ireland) and Worcester (England) during summer 2010. Observations were made using Hirsttype volumetric spore traps and corresponding optical identification at the genus level by microscope. The measurements at both sites (including meteorological parameters) were compared and contrasted. The relationships between the fungal spore concentrations with selected meteorological parameters were investigated using statistical methods and multivariate regression trees (MRT). The results showed high correlations between the two sites with respect to daily variations. Statistically significant higher spore concentrations for Alternaria, Cladosporium and Ganoderma were monitored at the Worcester site. This result was most likely due to the differences in precipitation and local fungal spore sources at the two sites. Alternaria and Cladosporium reached their maxima a month earlier in Cork than in Worcester, and Didymella with Ganoderma peaked simultaneously with similar diurnal trends found for all the investigated spore types. MRT analysis helped to determine threshold values of the meteorological parameters that exerted most influence on the presence of spores: they were found to vary at the two sites. Our results suggest that the aeromycological profile is quite uniform over the British Isles, but a description of bioaerosols with respect to overall load and daily concentration can be quite diverse although the geographical difference between sites is relatively small. These variations in the concentrations therefore need to be explored at the national level.

“…We think that there must be a combination of environmental factors a t the time of pollen release, which leads to the migration of proteins towards the apertures, from where they are released. A possibility worth investigating is that the pollen grains of birch may rupture after a thunderstorm or during rainfall, as in the case'of grass pollen (Packe & Ayres 1985, Bellomo et al 1992 9 n d Knox & Suphioglu 1996). In grass pollen, starch grains with allergens are liberated into the air when pollen grains are ruptured osmotically during rainfall or periods of high relative humidity (Knox & Suphioglu 1996).…”
