[Respiratory function tests in the newborn and the infant].

We evaluated respiratory mechanics in healthy or with respiratory diseases newborns and infants. We used a facial mask collected with a pneumotachograph and a software. We obtained flow-volume and flow-time loops which are useful for evaluating lung function in non collaborating infants.

[Basophil count of the newborn is not useful in prediction of allergic diseases].

Basophil granulocytes and their mediators are involved in the pathogenesis of allergic inflammation. We evaluated basophil count, blood histamine content, eosinophil count and serum total IgE levels in one hundred-thirteen healthy newborns at birth. 108 children were prospectively studied with a follow-up to 18 months of age for development of topic disorders.

[Eosinophils: current knowledge and clinical usefulness in childhood].

We describe the eosinophil granulocyte's immunobiology and pediatric management implications. Moreover, we review our results about eosinophil count in newborn as a predictive marker of atopy.
