Asthma ranges from mild to severe. Some people have only occasional, mild symptoms. Others have nearly constant symptoms with severe, life-threatening flare-ups.During an asthma attack, the airways become inflamed. They narrow as the muscles surrounding them constrict. Mucus produced by the ...
1.4.2. Reversible airflow limitation Wheezing and dyspnea during attacks are induced by reversible airway narrowing, which occurs diffusely throughout the airways and ranges from mild to severe. The peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV1) often differ markedly betwee...
The overall preferred treatment for all age ranges, in addition to patient education and environmental control, is: A. Low-dose inhaled corticosteroids (ICS) B. Short-acting beta-agonist C. Montelukast D. Long-acting beta-agonist Correct Answer ...
The prevalence of OSA in children with asthma ranges from 35 to 66%89,90; in adults, prevalence is reported to be 40–50%91,92. In the general population, estimates of OSA prevalence are in the range of 3–7%93. OSA is associated with more severe exacerbations in adults and poorer ast...
The annual incidence of occupational asthma ranges from 12 to 170 cases per million worked. The prevalence is reported at 5% to 15% across many different industries. Asthma is the most common noncommunicable disease among children. Most deaths occur in older adults. ...
Serum sodium and potassium concentrations and osmolality on admission were within normal ranges. The degree of dehydration correlated best with a fall in blood pH. There was no association between the degree of dehydration and the recovery of the peak expiratory flow rate during the first 24 hours...
Nonetheless, based on the application of standardized methods to measure the prevalence of asthma and wheezing illness in children4 and adults, it appears that the global prevalence of asthma ranges from 1% to 18% of the population in different countries (Figure 1-1)2,3. There is good ...
Cough, recurrent bronchitis, pneumonia, wheezing, and asthma are associated with gastroesophageal reflux (GER).[9, 10]The incidence of GER in those with asthma ranges from 38% in patients with only asthma symptoms to 48% in patients with recurrent pneumonia. Scintigraphic studies performed after ...
Studies show that adherence to ICS ranges from 40 to 70% [11–17]. The disruptive effect of non-adherence on asthma treatment implies that solutions are needed for improving adherence. Up to now, many interventions focus on education of parents and children. Review studies show that such ...
gValues in parentheses are interquartile ranges given in years. that shared the same comorbidity patterns (see Fig. 2a). Within each of the eleven subgroups that were re-discovered in UKB, we carried out a GWAS of asthma, identifying 14 loci that were also found in the initial larger GWAS...
