General aspects of the human ontogenesis are analyzed theoretically from the view point of behavioural biology. The functional integration of the three levels of individual development--actual genesis, ontogenesis, phylogenesis--leads the author to the term "hologenesis". Based on the concept of hologenesis developmental problems are discussed in terms of behavioural biology. In this context behaviour is defined as the organismic interaction with the environment on the basis on information of the hologenetic process. Behavioural data on fetal, neonatal, and postnatal life are discussed in relation to interaction with the peristatic milieu.

Eight anthropometric data from 550 healthy sporting girls aged 9-12 years are presented as percentiles in tabular form. The results are of importance for the medical practice.

Compared with the conventional ECG lead systems, the corrected orthogonal leads by Frank and the leads by Nelson constitute progress, especially if one considers their mathematical and physical comparability and the possibility of recording vectorcardiograms projected on to three orthogonal levels. The discussion about these lead systems and their application in infancy and childhood cannot be considered concluded; above all questions of their information content must be definitively clarified.

Non-traumatic injuries of the muscular-skeletal system and connective tissue are expressed typically in early childhood; in young adults the morbidity rate is high and serious health problems follow in later life. For prophylaxis to be successful, early specific diagnosis is necessary. In order to identify postural weaknesses and damage in the context of paediatric practice, the authors recommend a double test to evaluate condition and coordination (combination of Matthias's forward stretched arm holding test with Janda's test of abdominal muscle strength). They describe their own experience of conducting and evaluating these quick means of functional diagnosis and the problems of their use in the context of preventive medical examinations conducted by the Health Care for Children and Adolescents.

Data presented in this study prove that in term neonates as well as in premature newborns the normal postnatal fall of the body weight is of a smaller extend when breast milk, especially breast milk from their own mothers, is used for nutrition.

A review is given on the secular trend of the somatic development, on its part-phenomena and on the mutual interest of the human biology as well as the pediatric practice. The author presents two example of a positive secular trend in Hungary concerning the growth of height and the maturation in girls, respectively. This last one, however, shows also a negative tendency in the last decades.

Five measurements of body circumferences were related to the results of determinations of the subcutaneous fat thickness using caliper measurements. The analysis of data obtained from 10,661 infants and children aged between 1.5 to 15 years do not show constant correlations of the parameters measured during the periods of childhood.

As a consequence of advanced growth episondes and an increase in the final height of adolescents, resulting in changes in the cardiovascular system, an "acceleration" of electrocardiographic parameters and special morphological features of the ECG can be observed. The trend towards a closer relation between ECG parameters and body height than age, as seen in our probands as well as in the literature, reflects the influence of acceleration on the electrocardiogram.
