There are some striking examples of asthma attack periodicity, and much may be learned from these.
A list of suggested references (selected because of their relevance to primary care management of acute asthma), resources (e.g. guideline summary charts, web-sites of professional organisations, training organisations, equipment manufacturers) and practical materials (e.g. examples of asthma action plans) were provided to all participants and discussed in the workshops.
They have many functions in the onset and perpetuation, for example, of asthma [ 9].
Current quality indicators for asthma management in primary care focus on various quantitative measures at a practice level, for example percentages of asthma patients who have had a review in the past fifteen months, or who smoke and who have received smoking cessation advicer [ 39].
They cited the example of the asthma drug albuterol sulfate.
For example, the incidence of asthma among the city's children is growing, and along with it the cost of caring for these children in expensive emergency rooms.
An impressive example was elimination of asthma outbreaks in the enzyme detergent industry in the late 1960s and early 1970s (Cathcart et al. 1997; Schweigert et al. 2000).
For example, the presence of asthma in the mother, lifestyle factors such as smoking during pregnancy, or pre-term delivery all have been found to increase the risk of asthma [ 13].
For example, the diagnosis of asthma was assumed from simple self-reporting by patients [ 19, 25- 27]; and, in others, by their responses collected in a telephonic survey addressed to recognize asthma symptoms [ 17].
Secondly, because this study was initially designed to address the issue of childhood sleep, there were some important allergic risk factors that were not included, for example, family history of asthma and allergies, and indoor and outdoor allergens.
However, ruling out in younger patients was only effective with recurrent respiratory tract infections when allergic signs were absent; then, as an example, the probability of asthma was 18.1% (95% CI 9.58%too 26.7%) when FENO was ≤16 ppb in a 20-year-old patient.
