Parameters of lung inflammation in asthmatic as compared to healthy children in a contaminated city.

Background: The impact of air pollution on the respiratory system has been estimated on the basis of respiratory symptoms and lung function. However; few studies have compared lung inflammation in healthy and asthmatics children exposed to high levels of air pollution. The aim of the study was to elucidate the modulatory effect of air pollution on Cysteinyl-leukotrienes (Cys-LTs) levels in exhaled breath condensate (EBC) among healthy and asthmatic children.

[Lidocaine with epinephrine effect on arterial tension of children].

Objective: to determine the effect of the epinephrine-lidocaine anaesthetic solutions on blood pressure in healthy children subjected to short dentistry procedures.

Methods: we performed a prospective, observational and analytical study in 39 children with 7 and 8 years of age, who were subjected to dentistry treatment of short duration in a dentistry service. The blood pressure was measured in three times: previous to the infiltration of lidocaine to 2 % with epinephrine; 10 minutes later; at the end of procedure.
