[Acute effect of maternal smoking on fetal blood circulation].

The authors examined the acute effects of cigarette smoking on maternal and fetal cardiovascular system in 22 healthy voluntary pregnant smoker women. All examined patients were chronic cigarette smokers who smoked more than 5 cigarettes per day before and during pregnancy. All of the pregnancies subsequently had normal outcomes. Maternal heart rate, and blood pressure, fetal heart rate, resistance indices of fetal descending aorta, those of umbilical artery, middle cerebral artery and uterine artery were measured immediately before and after cigarette smoking. It was found that smoking was associated with increase in maternal and fetal heart rate and an increase in umbilical artery resistance indices was also observed. These changes might be considered as a reaction improving fetal oxygen supply.

[Practical questions about organizing a gynecologic outpatient clinic for climacteric-osteoporosis patients].

The author established a climacteric-osteoporosis outpatient clinic at his department of obstetrics and gynecology among the first ones in Hungary. On the basis obtained with the care of 3000 patients the author outlines the most important duties connected with such a clinic. In his opinion it is of special importance to screen women with several risk factors for postmenopausal osteoporosis,--supply these women at risk with hormone replacement therapy (HRT) and to care them,--include diseases which contraindicate HRT before starting it, --work out rational cooperation between the interested specialties and to delimit the duties,--make the rules of direction of patients clear,--supply osteoporotic women treated by rheumatologists with HRT, --use uniformed diagnostic and therapeutical protocol, --inform the women population and to prepare the specialists and family doctors and to take part in their further education. According to experiences of the author HRT is especially effective to stop climacteric complaints and to prevent and treat osteoporosis.

[Incidence of intrauterine growth retardation and its significance in perinatology in Hungary].

The authors have examined the incidence of intrauterine growth retardation at a country level for the first time both in local and international aspect. Using the nomenclature of NDN-system they have found the frequency of WL-(proportional) retardation 7.95% and that of N-(disproportional) retardation 5.99%. They show incidence of retardation from county to county, as well. Examining the correlation between retardation and perinatal mortality they've stated that while the frequency of still-birth among the average developed and proportionally nutrified fetus is 0.34% and the frequency of perinatal mortality among them is 1.23%, that of the N-retardated newborns is 0.88% and 2.08%, respectively, and that of the WL-retarded is higher than the latter: 2.03% and 3.90% respectively. Regarding the incidence and mortality ratio among the two types of retardation the difference is significant.

[Clinical significance of intrauterine growth retardation].

The authors have examined the measure of the influence of the proportional and disproportional retardation on the results of the pre- and subnatal observation of the fetus and on the frequency of perinatal mortality and newborns' morbidity, premature birth and newborns born with low birth weight. The authors have stated the two types of retardation leads to a higher global perinatal mortality mainly by causing a more frequent intrauterine mortality. Comparing the results of the retarded newborns to those of the somatically normally developed neonates they prove it from several aspects that the proportional retardation means a much higher risk for the newborn than the disproportional retardation which is also a risk factor. The new NDN classification system elaborated and used by the authors is suitable for differing the two types of retarded newborns.

[A new method for the classification of neonates based on maturity and somatic development].

The author points out the sad fact that the methods of estimating classifying, comparative examining of the maturity, somatic development of newborns and the methods of marking off the retarded newborns used up to now are essentially centering round the birth-weight. He exposes the errors, deficiencies of these methods and confronts them with the possibilities of the NDN-system (newborn's somatic development and nutritional state) worked out earlier by him. He thinks the NDF-system to be able to express simultaneously and exactly the gestational age, weight- and length-development, state of being fed of the newborns and the relation to the populational average, the fact and type of retardation, as well. The informational means of NDF-system in NDF-index. The NDF-system makes it possible to break down the birth-weight centric view as it offers a more suitable and qualified method than used before to describe the maturity and somatic development and the classifying of the newborns on the basis of these.

[Representation of the increase of fetal biparietal and thoracic diameter on a new (14-zone) ultrasonic diagnostic table].

From the somatic development of the fetus one may conclude to its functional maturity and if birth is near to its life prospects too. Thus the ultrasonographic examination of the biparietal and thorax transversal diameter reflecting the somatic development is of prognostic significance too. The authors composed a new table to increase the information value of the ultrasonographic finding, for the uniform designation of the given BPD and THD (biparietal and thorax diameter) sizes and for the better recognition of the tendencies of BPD and THD changes. A new system of symbols and representation method were elaborated for the description of standard positions. According to the gestation weeks 14-14 BPD and THD size-ranges were separated. The so called "UFD" Ultrasonographic index of the Fetal Development gives information besides the gestation time also on the BPD and THD standard position of the fetus and demonstrates illustratively the direction and rate of deviation of the standard positions from the average. The system provides the possibility of a better information to the obstetrician or consulting physician who evaluates the US finding, a uniform interpretation of the findings and serves better the clinical diagnostics.
