[Foreign bodies in respiratory tracts of children treated at the Institute of Pediatrics in Krakow during the years 1987-1991].

Foreign bodies aspirated into respiratory tract may produce severe lung damage and threaten life. We have analysed retrospectively symptoms, physical findings, chest roentgenograms and bronchoscopy reports in 20 children with foreign body aspiration. Boys dominated in this group. Foreign body aspiration often accompanied by coughing, wheezing and vomiting. In chest X-ray examination it was revealed unilateral body trapping and obstructive emphysema. Foreign body aspiration should be considered in children with prolonged respiratory tract problems even when no adequate history is present and with negative chest roentgenograms.

[Standards in evaluating the test of obstruction reversibility based on the flow-volume curves].

The study analyzed the changes in the shape of the flow-volume curve after fenoterol (Berotec) inhalation in school age healthy children. Significant increase of FEF25-75%, FEF50%, FEF25% values were seen. The authors demonstrated that bronchodilatation was not related to sex, height, weight and children's age, but it's value is indirectly proportional to the at-rest state of the airways. It seems, basing on results of this study, that FEV1 and FEF25-75% are the best indexes of dilatation tests. Increases of 10% and 30% are significant of bronchodilatation.
