          Abstract

          The analysis of short-term growth needs repetitive measurements of body stature or of segments of the body. When body stature is measured at monthly intervals, an irregular incremental pattern becomes obvious with a number of large-scale components such as series of prepubertal and pubertal growth spurts, seasonal influences on height gain, and influences of the psychosocial and economic background. When measurement intervals decrease, incremental patterns appear even more irregular, and a number of short-scale components become apparent that are distinct from measurement error. The review summarizes the analysis of short-term growth, and presents the current findings supporting different views on how growth progresses at short term. In particular, observations are presented that suggest growth being a pulsatile, a periodic, a saltatory, and a chaotic event. Some recent animal studies and studies in human newborns are added in detail as they illustrate short-term growth on the basis of accurate 24-hour measurements of the lower leg. The latter investigations support the idea of short-term growth being characterized by chaotic series of ‘mini growth spurts’ that occur at intervals of approximately 4–5 days, not only in human neonates, but also in rats. The amplitude of mini growth spurts ranges between 2 and some 10 mm, and growth velocity of each spurt also varies considerably so that one spurt needs between less than 1 and up to several days for completion.

          Long-, intermediate- and short-term growth studies in asthmatic children treated with inhaled glucocorticosteroids.

          During recent years, new auxological techniques have been introduced for assessment of the risk of growth suppression in asthmatic children treated with exogeneous glucocorticosteroids. Assessment of lower leg growth rates with the knemometer has made short-term studies of growth processes under strictly controlled conditions possible. However, short-term lower leg growth rates cannot be used for estimations of intermediate-term height growth rates or long-term evaluations of final height. Consequently, the distinctions between the various types of growth studies in asthmatic children treated with inhaled glucocorticosteroids have become important and need to be discussed. The present paper presents a review of the long-, intermediate- and short-term growth studies available. The bulk of evidence from intermediate- and short-term evaluations indicates that growth rate is not affected when standard paediatric doses of inhaled glucocorticosteroids are used. However, further focus needs to be placed on differences between specific glucocorticosteroids, doses and delivery systems. Intermediate- and short-term growth data should be evaluated in the long-term perspective.
