[Risk factors for atopy in schoolchildren from Cracow].

The aim of the study was to assess atopy and its risk factors in school children from Cracow. A survey of atopy in the 223 children, aged 12-14 years, in relation to developmental, environmental and social factors, was conducted in the three districts of Cracow. Atopic sensitization (SPT > 3 mm) was more prevalent in children from highly polluted district of the Stare Miasto than in children living in Prokocim and Nowa Huta (34.

Input respiratory impedance measured by head generator in preschool children.

The upper airway wall motion represents a serious problem when measuring the input impedance of the respiratory system (Zrs) by the forced oscillation technique, particularly in young children. To minimize this error, it has been proposed to vary transrespiratory pressure around the head rather than directly at the mouth, using the head generator technique (HGT). The aim of this study was to collect normative data in preschool children in whom the technique may prove most useful.

[Predictive values of peak expiratory flow measured with mechanical meters for Polish children and adolescents between 7-19 years of age].

The aim of this study was to evaluate the predicted values of pack expiratory flow for the Polish children and youth by means of measures Mini Wright and Personal Best. The accounts were based on a group of 86 boys and 110 girls. It was established that it was necessary to state different predicted values for different measures and that an optimum model of regression for counting of predicted values of PEFR in relation to body height for the Polish children and youth was an exponential model.

Forced oscillation technique (FOT): a new tool for epidemiology of occupational lung diseases?

The aim of this study was to evaluate the usefulness of the forced oscillation technique (FOT) in the assessment of occupation-related airway changes. The forced oscillation technique and conventional lung function tests were applied in 80 underground coalface workers, aged 35-48 yrs, with chest roentgenogram films classified 0/1 or 1/0 according to the International Labour Office (ILO) classification (G group), and two control groups matched for age and smoking habits. The first control group, was made up of face-workers having normal chest radiographs, whilst the second comprised underground non-face-workers with normal chest radiographs.

[Forced oscillation technique in respiratory system studies. III. Compliance and airway resistance in children with lung fibrosis].

In patient with lung fibrosis we need to monitor lung compliance to evaluate the progress of the illness or efficacy of the treatment. This examination is not well tolerated and difficult to perform, especially in children. We compared classic measurements of static compliance of the lung and airway resistance with parameters derived from forced oscillations measurements--compliance and resistance of respiratory system.
