[Estriol serum levels following betamethasone treatment for induction of fetal lung maturity (author's transl)].

23 pregnant women with 28 to 37 weeks of gestation, threatened by premature labor, received Betamethasone 8 mg at admission and 4 mg 24 hours later to prevent newborn-RDS. Four women experienced this treatment twice. Blood was sampled for determination of estriol before each administration of Bethametasone and 24 hours after. Group I, patients with no signs of placental insufficiency, showed a drop in estriol levels at the second sample, but these recovered at the third one. There was no recovery seen at the third sample with group III, representing patients with proven placental insufficiency. Patients demonstrating pathologic CTG or delivering babies with low Apgar scores (Group II) showed no consistent course with their estriol levels. The course of estriol after administration of Betamethasone may be used as a test to determine the quality of the feto placental unit.

[Intrauterine pressure and fetal and maternal heart rate on administration of the betamimetic agent, hexoprenaline during labour (author's transl)].

The tocolytic effect of hexoprenaline was determined in 20 women by internal cardiotocography during labour. After 30 minutes of intravenous medication (0.3 microgram/min = dosage for massive tocolysis) the uterine activity decreased on average by 73.6%; the maternal pulse rate increased by 25.0%; the fetal heart rate showed no significant change.

[Pregnancy and delivery in 12 to 15 year-old girls (author's transl)].

From January 1st 1974 to March 1st 1980, altogether 51 girls under the age of 16 were admitted for delivery at the 2nd Department of Obstetrics and Gynaecology, University of Vienna, Medical School. By means of the following parameters, i. e. premature birth rate = 5.9%, rate of gestosis (GI greater than 3) = 3.9 and perinatal mortality rate = 0, the question of clinical assessment of gestation as high-risk pregnancy in the case of young girls in discussed yet again. For the total number of reported cases within the specified period, the rate of premature birth is 8.7%, the corresponding rate of gestosis is 6.7 and the overall perinatal mortality rate is 1.6%.

[The place of sonography in the diagnosis of recurrence of malignant gynaecological tumours (author's transl)].

The scope of sonography in the diagnosis of tumour recurrence is discussed on the basis of 134 patients with suspected recurrence of malignancy. In 67 cases recurrence was verified by means of ultrasonic diagnosis. In 63 cases the tentative diagnosis proved to be negative. In the remaining 4 cases the examination result was equivocal. The ultrasonic results were compared with physical examination, I.V.P., scintigraphy, histological examination of specimens of second-look operations and curettages, and autopsy material. It is pointed out that small tumours posterior to the urinary bladder can be overlooked because of the enhancement caused by the impedance mismatch between the fluid-filled bladder and the solid structures posterior to it. In cases of local and lymphonodal recurrent tumour the examination is extended to the upper abdomen to detect possible hydronephrotic changes. Two different echographic patterns can be observed after primary irradiation of cervical and endometrial cancer. The enlarged uterus with inhomogeneous structures is more likely to be a recurrent tumour. A more "cystic" appearance of the enlarged organ would suggest a mucometra caused by cervical occlusion. In recurrent ovarian tumours ascites is detectable which sometimes even disturbs the examination owing to the extreme curvature of the abdominal wall hindering a sufficient coupling of the probe. Ultrasound is applied with good results in irradiation planning and for the monitoring of therapeutic results.

[Comparative determination of the vesico-urethral angle in incontinence via ultrasound and lateral urethro-cystogram (author's transl)].

Pre-operative diagnostic procedures in evaluating stress urinary incontinence in women became increasingly important within the last years. In many clinics the measurement of the posterior vesico-urethral angle using lateral urethro-cystograms has become an eminent criterion for the selection of the operative method applied. Until now, this angle could be measured by employing X-ray examination techniques. In this paper, an ultrasonic examination with the same accuracy as in X-ray. The technique of both methods and their advantages and disadvantages are discussed.

[The position of the IUD and intrauterine pregnancies].

In 59 women who became pregnant with an IUD the position of the device was controlled by ultrasound. Before the 9th week of pregnancy the device was located in 40 women (78.4%) in the cervix or in the isthmic region of the uterus. In 11 cases the IUD was in correct position. 8 women had a pregnancy of more than 9 weeks and were not included in the study as the gestational sac could have influenced the IUD position. The possibility of regular control of the IUD position by ultrasound is discussed in order to reduce the failure rate of this contraceptive method.

[Comparison of different methods for estimating fetal weight by cephalo- and abdominometry (author's transl)].

To check the accuracy of different published methods of fetal weight estimation based on head and abdominal parameters, all methods were used in every individual case in 123 pregnancies. It became apparent that the single methods gave the best results in different indications. As far as normal fetal development at term is concerned the best results were achieved by estimating the weight from the biparietal and the abdominal diameters whereas in macrosomy the prediction of fetal weight became much more precise in using head and abdominal circumferences. In premature and small-for-date infants, however, the best results were recorded if only the abdominal circumference was used for this reason reflecting the importance of the severe reduction in volume of the big parenchymateous organs of the abdomen.

[Control of IUD-position (author's transl)].

The correct position of an IUD in the uterine cavity is essential for the effectiveness of the method. Ultrasound examination of the thickness of the anterior and posterior wall of the uterus were carried out and their relation to a correct position of the IUD calculated. It was found that the position of the IUD is correct, if the distance between fundus and the cranial end of the IUD does not exceed the thickness of the uterine wall by more than one-third; i. e. in all 4/3 of the thickness. The correlation between the ultrasound results of length, version and flexion of the uterus and complaints and side-effects like bleeding and pain are discussed, especially if the IUD is not in correct position.

[Ultrasonic diagnosis in cervical pregnancy (author's transl)].

The cervical pregnancies are most times complicated by severe uterine haemorrhages which can be stopped generally only by hysterectomy. Ultrasonic diagnosis provides new possibilities in diagnosing this dangerous localization of pregnancy prior to the onset of clinical symptoms. The characteristic sonographic findings of two cases are discussed: one early and one advanced case, both were symptomless. Although in rare cases a delivery at term could be observed, the termination of pregnancy seems to be indicated in cases of a doubtless ultrasonic diagnosis.

[Pregnancy-conditioned dilatation of the calyceal system-sonographic diagnosis and urologic control (author's transl)].

Ultrasonic diagnosis provides the possibility without any irradiation hazards to follow-up the urinary excreting system in pregnancies as often as necessary. Thus it becomes possible to detect the true percentages of pregnant women with dilatation of the calyceal system, and to evaluate the course of dilatation in those women examined at different intervals. There exists as well the possibility to avoid urinary tract infections by an intensive urologic surveillance in such cases.

[Early diagnosis of fetal malformation by ultrasonography (author's transl)].

Today, echography can be considered as routine diagnosis in every pregnancy. Besides the detection of growth retardation very often in early stages of the fetal life malformations can be diagnosed incompatible with postnatal life. Reviewing the cases of the II. Women's Department of Obstetrics and Gynaecology in Vienna within the last 2 years, 13 cases of serious malformations could be detected by regular routine ultrasonic examinations. The echographic appearance of these partially very rare cases is discussed and documented by pictures. The advantage of ultrasonic diagnosis in comparison with other diagnostic procedures in the detection of malformation is discussed. The necessity and importance of regular ultrasonic examinations of all pregnancies as well in respect in the detection of malformations are stressed.

[The pregnant and non-pregnant rudimentary horn of an uterus (author's transl)].

In the past 10 years three cases of pregnancy in a rudimentary horn of a double uterus and one case of haematometra were observed at the second university hospital for women in Vienna. The problems of the development of a pregnancy in the uterine cavity of a rudimentary horn which is not connected to the main uterine cavity are discussed. The clinical course of such a pregnancy is discussed reviewing our own cases and those reported in the literature.

[Ultrasonic diagnosis of fetal ascites (author's transl)].

Fetal ascites is relatively rare, but confronts the obstetrician with difficult decisions. By X-ray methods such as plain X-ray or fetography fetal ascites may only be suspected. Performing ultrasonic examinations however it is not only possible to detect the fluid collection in the peritoneal cavity but as well to recognize the inducing causes. This is documented by sonograms of three cases observed within the last year. The different decisions for the obstetrician in respect to fetal ascites with or without malformations are discussed.

[Ultra-sound study on the growth of the fetal kidney in the second half of pregnancy (author's transl)].

Sonography was used to detect and measure the fetal kidneys. In 250 cases of pregnancies ranging from the 20th week to term growth charts for the normal growth of the fetal kidney were constructed. Considering the normal anatomical variations it is possible using these curves to detect growth retardations of the fetal kidneys. The importance of these measurements for fetal anomalies and cases of placental insufficiency with growth retardation of these organs is discussed.
