[Effect of maternal age on birth weight and duration of gestation].

We analysed the influence of the mother's age on the weight of the newborn of a total of 7.715 newborn infants (3.922 boys and 3.

[Effect of body measurements of the parents and parity on the body weight of the newborn infant].

Percentiles of birth weight are important tool for correct diagnosis of hypotrophy. Percentile curves, derived from newborns of the GDR, consider only the infant's sex. Parity and parental physical characteristics have essential influence on the weight of the newborn infant.

[Normal standards for birth weight and birth length of newborns in the DDR].

Normal anthropometric standards of birth weight and birth length are presented for newborn boys and girls in the GDR between 28 and 44 weeks' gestational age. Newborns with uncertain duration of gestation, multiple births, malformations and stillbirths have been excluded. It is directed to necessity of regional standards.

[Effect of the protein-free calf-blood-extract (Solcoseryl) on the excretion of estrogens in chronic placental insufficiency].

In a double blind study the action of Solcoseryl was tested in 31 patients during late pregnancy with chronic placental insufficiency. Under treatment with Solcoseryl a significant increase in urinary estrogen excretion occurred in relation to the placebo-group.

[Production of obstetrical reports using a computer].

A rational method of production of medical reports in obstetrics is reported. The basis of this method is the approved computer guided system (DOKUMEDA) in clinics of radiology. Advantages and disadvantages of using are discussed.

[Results of a standard value determination concerning newborn infants in the German Democratic Republic. IV. Methodological problems of the determination].

Proof of the data are characterized and recommended, which have been executed at the data of the newborns. Both definitions of the percentiles used in the similar measurements are compared with their advantages and disadvantages. The exactness of the results contained in the 1st and 2nd paper is presented in a table.

[Body measurements and morphological signs of maturity in newborn infants after hyperemesis gravidarum].

Birth weights from 128 males and 139 females born between the 39th and 42nd week of pregnancy whose mothers suffered from hyperemesis gravidarum were compared with normal groups of newborns. In the hyperemesis group, the females were on an average 97 g (p less than 0,05) and the males 61 g (p greater than 0,05) heavier than in the control groups. Birth lengths and cephalic measures differed not in both groups.

[Results of a standard value determination concerning newborn infants in the German Democratic Republic. III. Morphologic assessment of maturity].

A simple technique for estimating of maturity in 15589 newborns without technical expense were performed in connection with the examination of birthweight, length, head circumference and head diameters at a gestational age of 31st to 44th week in 21 women's clinics in the GDR. The estimation of maturity is based on the gradual assessment of 8 external physical characteristics. The coefficients of correlation is not differed between characteristics of maturity, measures of newborns and duration of pregnancy.

[Results of standard-value determinations in newborn infants in the German Democratic Republic. II. Head circumference, biparietal and fronto-occipital diameter].

Using the measurements taken from 6645 male and 6381 female newborns from the GDR-population the normal values from head circumference, fronto-occipital and biparietal diameter are reported. The results were given in relation to duration of pregnancy (31. to 44.

[Changes in the binding capacity of thyroxine-binding globulin (TBC), of total thyroxine (T4), of the free thyroxine index (FT4-I) and of thyrotropin (TSH) during normal pregnancy and in hydatidiform mole].

TBC-index and total serum thyroxine were measured in 100 healthy nonpregnant and in 163 pregnant women during the 8. and 41. weeks of gestation.
