OBJECTIVE: In preschool children, diagnosis of asthma is difficult because of not using spirometry objectively. instead of spirometry, other techiques that not required sedation and cooperation to evaluate pulmonary functions. Interrupter technique that measures the resistance of the airway, is one of these methods. Insufficient of references values hamper the use of this technique commonly. In this study,to determine the referencesal values of Turkish preschool children for interrupter technique is intended. METHODS: 50 healthy children who applied between January 2008 and September 2008 to the Behcet Uz Children Hospital, were accepted for this study. During the expiratory phase of tidal breathing interrupter technique for airway resistance measurements were performed. At least 5 measurements were made for each case, and median values of these measurements were the base. References values were determined according to age and height. RESULTS: There were 28 boys (%56), 22 girls (%44); the average age is 3.2 ± 1.8 years respectively. The average value for Rint 0.489 kPa. L-1. s was determined.Rint values decrease with increasing age was observed (p <0.001). Rint value with the increase in height was found to be a significant reduction (p <0.001).Rint values will be calculated using the height parameter equation (Rint (e) = 1948-0015 × (cm)) was developed. CONCLUSION: Interrupter technique in preschool children with objective measurements of airway resistance will help in the diagnosis of asthma.Knowing reference values of healthy children may enable disseminated use of this tecnique.OBJECTIVE: In preschool children, diagnosis of asthma is difficult because of not using spirometry objectively. instead of spirometry, other techiques that not required sedation and cooperation to evaluate pulmonary functions.

There are numerous problems regarding lung function assessment in infants and preschool children despite the great interest to this field worldwide. Therefore, investigations of the interrupter technique in infants and preschool children are of great importance. This article contains results of measurement of airway resistance in children with asthma, atopic dermatitis, acute bronchitis and croup and in healthy children using the interrupter technique. Results of mathematic modeling have also been discussed in the article.

BACKGROUNDInterrupter respiratory resistance (Rint) is reported to be useful in evaluating lung function in poorly collaborating patients. However, no reference values are available from large samples of preschool children using the standard interrupter method. The aim of this study was to define reference Rint values in a population of healthy preschool children.METHODSRint was assessed without supporting the cheeks in children with no history of wheeze from six kindergartens. To evaluate the effects of upper airway compliance on Rint in healthy children, an additional group of preschool children with either no history of wheeze or no respiratory symptoms at the time of testing underwent Rint measurements in our lung function laboratory with and without supporting the cheeks. Short term (about 1 minute apart) and long term (mean 2.5 months apart) repeatability of Rint measurements (2 SDs of the mean paired difference between measurements) was also assessed in children referred for cough or wheeze.RESULTSA total of 284 healthy white children (age range 3.0–6.4 years) were evaluated. Mean inspiratory and expiratory Rint (Rinti and Rinte) did not differ significantly in boys and girls. Age, height, and weight showed a significant inverse correlation with both Rinti and Rinte in the univariate analysis with linear regression. Multiple regression with age, height, and weight as the independent variables showed that all three variables were significantly and independently correlated with Rinti, whereas only height was significantly and independently correlated with Rinte. Supporting the cheeks had no significant effect on Rinti (n=29, median 0.673 v0.660 kPa/l.s, p=0.098) or Rinte (n=39, median 0.702v 0.713 kPa/l.s, p=0.126). Short term repeatability was 0.202 kPa/l.s for Rinti (n=50) and 0.242 kPa/l.s for Rinte (n=69). Long term repeatability was 0.208 kPa/l.s for Rinte (n=26).CONCLUSIONSWe have reported reference Rint values in preschool white children and have demonstrated the usefulness of this technique in assessing lung function in this age group.

The aim of this investigation was to study the relationships between physical activity, motor ability, and school readiness in 6-yr.-old children. In total, 294 healthy children from Tartu were studied (161 boys and 133 girls). The physical activity of children was reported by parents and teachers using the questionnaire of Harro. The motor ability of children was evaluated using various tests from the Eurofit test battery as well as the 3-min. endurance shuttle run test. The Controlled Drawing Observation test was used as a predictor of school readiness and development of mental abilities. Indoor physical activities predicted 19–25% of total variance in motor scores for these preschool children. Motor ability tests, which demand children's total attention and concentration, appear related to the chosen measures of school readiness.

The goal of the present study was to test the method of forming or actualizing preverbal concepts in the conditions of an independent search for a task solution in order to use the method in clinical practice. The conditions of the absence of researchers instructions allow: 1) to compare in ontogenetic and clinical aspects; 2) to develop the skills of an independent search for solutions in problem situations; 3) to improve the creative potential of a child; 4) to develop the ability to achieve a goal. The advantage of using the preverbal concepts of size and shape is that this method can be applied to children of primary preschool age and children with a delay in speech development. To test the method, 7 healthy children of the middle preschool age (4-5-year-old children) were selected. The first task was to form or actualize the concept of a bigger or smaller size in children during the simultaneous presentation of 4 flat or volume geometrical figures. The second task was to form or actualize the concept of a flat or volumetric object among simultaneously presented 4 figures of the same size (small, medium or big). To get reward children should have chosen the figure, which was different from the other 3 ones in a trial during the formation of both the concepts. In the both tasks, we calculated the quantity of trials, which were needed for the single attainment or excess of the 70% level of the correct task performance per each type of learning. The behavioral results showed that the learning speeds during the formation of the concepts of the bigger/smaller size and flat/volumetric shape did not significantly differ from each other. It could be suggested that those concepts were equally important for the 4-5-year-old children. The study showed that the concept formation model is a convenient psychological method for testing the level of the development of the higher cognitive functions in participants and its use is possible in clinical practice with the parallel recording of the brain activity (EEG, evoked potentials etc.) in children in the process of their performing cognitive tasks. The described model is promising for identifying intellectual developmental delays in preschool children and can be used to test children with various cognitive abnormalities.
