Modifications in forced vital capacity during adenosine monophosphate-induced bronchoconstriction in asthma: relationship with the response to methacholine and the effect of inhaled corticosteroids.
The effect of adenosine monophosphate (AMP) on forced vital capacity (FVC) has never been systematically investigated. ⋯ Although the AMP-induced decline in FVC in asthmatic patients is similar to that observed with equipotent concentrations of methacholine, the apparently different effect of ICSs on changes in FVC induced by each agonist suggests that the information provided by the 2 bronchoconstrictor agents is not interchangeable and that the information generated by the analysis of the effect of each agonist on FEV1 and FVC may be complementary.

To review habit cough and its treatments to raise awareness of this condition as a potential cause of chronic cough. ⋯ It is important to consider habit cough in the differential diagnosis of chronic cough because early diagnosis can help to avoid unnecessary invasive procedures and potential iatrogenic complications.

Repeated hospital encounters for asthma in children and exposure to traffic-related air pollution near the home.
Aggregate hospital encounters for asthma (admissions or emergency department visits) have been associated with daily regional air pollution. There are fewer data on relationships between repeated hospital encounters and traffic-related air pollution near the home. ⋯ Associations for repeated hospital encounters suggest that locally generated air pollution near the home affects asthma severity in children. Risk may begin during infancy and continue in later childhood, when asthma diagnoses are clearer.

The incidence of wheeze is unknown and the role of early life wheeze in subsequent health is not clearly understood. ⋯ Wheezing at any particular time in early life may not be predictive of early childhood lung function.

Prescriptions for self-injectable epinephrine and follow-up referral in emergency department patients presenting with anaphylaxis.
Anaphylaxis guidelines recommend that patients with a history of anaphylactic reaction should carry self-injectable epinephrine and should be referred to an allergist. ⋯ Most patients dismissed after treatment for anaphylaxis did not receive a self-injectable epinephrine prescription or allergist referral. Emergency physicians may be missing an important opportunity to ensure prompt treatment of future anaphylactic reactions and specialized follow-up care.
