There is limited evidence for the role of air pollution in the development and triggering of wheezing symptoms in young children. A study was undertaken to examine the effect of exposure to air pollution on wheezing symptoms in children under the age of 3 years with genetic susceptibility to asthma. ⋯ Air pollution related to traffic is significantly associated with triggering of wheezing symptoms in the first 3 years of life.

Randomized Controlled Trial Multicenter Study
The role of a soluble TNFalpha receptor fusion protein (etanercept) in corticosteroid refractory asthma: a double blind, randomised, placebo controlled trial.
Tumour necrosis factor alpha (TNFalpha) is a cytokine recognised as a therapeutic target in chronic inflammatory diseases. ⋯ Etanercept therapy over 12 weeks demonstrated only a small but significant improvement in asthma control and systemic inflammation, as measured by serum albumin and CRP. Larger randomised, placebo controlled trials are required to clarify the role of TNFalpha antagonism in subjects with severe refractory asthma.

Randomized Controlled Trial
Mechanisms of dyspnoea relief and improved exercise endurance after furosemide inhalation in COPD.
This study examined the effects of inhaled furosemide on the ventilatory and perceptual response to high-intensity constant-load cycle exercise in chronic obstructive pulmonary disease (COPD). ⋯ Alleviation of exertional dyspnoea after single-dose furosemide inhalation in COPD is multifactorial but improvements in dynamic ventilatory mechanics are contributory in some individuals.

Chronic obstructive pulmonary disease (COPD) is often associated with other chronic diseases. These patients are often admitted to hospital based rehabilitation programmes. ⋯ Most patients with COPD undergoing pulmonary rehabilitation have one or more comorbidities. Despite the fact that the presence of comorbidities does not preclude access to rehabilitation, the improvement in exercise tolerance and quality of life after rehabilitation may be reduced depending on the comorbidity.

Review Comparative Study
Montelukast as add-on therapy to inhaled corticosteroids in the treatment of mild to moderate asthma: a systematic review.
To systematically review the evidence for the medium to long term benefits and risks of montelukast as add-on therapy to inhaled corticosteroids (ICS) in comparison with placebo and active controls in mild to moderate asthma. ⋯ Montelukast as add-on therapy to ICS improves control of mild to moderate asthma compared with ICS monotherapy. Although the addition of salmeterol to ICS is clinically as effective as or even more effective than the addition of montelukast, montelukast may have a better long term safety profile and offer a treatment alternative for asthma patients.
