ABSTRACT
Our objective was to investigate the effects of age, weight, body mass index (BMI), sex steroid receptor status and serum parameters such as estradiol, testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEAS) and leptin on the size of a malignant breast tumor. A total of 62 premenopausal (median age 44.0 years) and 151 postmenopausal (median age 59.1 years) Caucasian women undergoing lumpectomy or mastectomy for invasive breast cancer were examined. Patient parameters (age, body weight, BMI), tumor parameters (tumor size, estrogen and progesterone receptor status) and serum parameters (estradiol, testosterone, androstenedione, DHEAS and leptin) were measured. An increase of BMI and DHEAS levels was associated with larger tumors by partial correlation (rp) analysis (rp = 0.418, p = 0.008; and rp = 0.329, p = 0.041, respectively), whereas higher androstenedione levels corresponded with smaller tumors. Furthermore, BMI, androstenedione and DHEAS levels were correlated: an increase in DHEAS was associated with higher androstenedione serum concentrations (rp = 0.603, p < 0.001), but was also associated with a lower BMI (rp = -0.378, p < 0.001). BMI and androstenedione serum concentrations were also associated (rp = 0.242, p = 0.009), thus closing a circle of mutual interactions. We conclude that, although breast cancer progression is characterized by autonomous growth that has become independent of growth regulatory mechanisms, tumor size at the time of detection is influenced by a complex system of counter-regulatory feedback mechanisms that might represent the body's physiological attempt to control the size of a malignant tumor.

OBJECTIVE: Maternal immunoreaction against the embryo can be responsible for fetal growth retardation. The secretion of PLF during pregnancy could be reliable for a diminished immunoreaction of maternal lymphocytes against the embryo. The aim of the present study was to elucidate a possible correlation between PLF and fetal growth retardation. METHODS: In this study, blood samples of 402 pregnant women were obtained between the 12th and 16th weeks of gestation. The serum levels of PLF were compared with birth weight, percentile of birth weight, and gestational age. RESULTS: Women with children whose birth weight was below or equal to the 10th percentile for gestational age showed significantly lower PLF levels (11.4 U/ml, n = 107) as compared with women whose newborns were of normal weight (19.9 U/ml, n = 295; p < 0.004). CONCLUSION: Determination of the PLF level could serve to identify women at risk of having growth-retarded babies.

This study investigates the reliability of ultrasonographic screenings for detecting fetal malformations in pregnancy. The data from 1505 screening examinations of pregnant women who underwent routine checks at the Department of Obstetrics of the University of Vienna, were compared with the anomalies diagnosed in the newborn of the same collective. Fetal malformations were diagnosed in 28 screening cases. The statistical distribution of these anomalies is shown for the different organ systems. In 5 newborn malformations were found, which had not been diagnosed sonographically. Another 23 newborn had minor malformations in regions that are not included in the routine screening ultrasound. The results show a high accuracy of the sonographic screening examination, with the exception of the median facial region and the large vessels of the base of the heart. The fact that not all of the cardiac malformations were diagnosed prompts the performance of an extended sonographic inspection of the fetal heart within the framework of routine screening.

The aim of our study was to examine the effects of hormone replacement on the size of the uterus and the development or increase of myomatas. Fifty perimenopausal women were included in the study (53.8 +/- 5.0 years). Patients received a substitution therapy composed of a combination of 4 mg estradiovalerate and 200 mg prasteronenantate (Gynodian Depot cartridges) given as a muscular injection in 6-10 week intervals (mean 7 weeks +/- 4 days). Prior to the onset of therapy with Gynodian and after a period of 12 months (+/- 13 days) vaginosonography was performed. Measurements taken were length, thickness, height of endometrium, size of ovaries and of myomas. Data obtained were correlated with baseline findings. Within 1 year, significant increases in uterus length from 73.4 mm to 88.2 mm, in uterus thickness from 33.9 mm to 43.5 mm and in endometrium height from 4.1 mm to 6.7 mm were observed (median values). There was an increase in both the number (from 2.2 to 3.5) and the size of the myomatas (29.4-35.0 mm diameter). A statistical analysis conducted by means of the Wilcoxon matched pairs signed-rank sum test showed P < 0.001. No significant change occurred in the size of the ovaries. Our study shows that hormone substitution may have an impact on uterus growth and that therefore vaginosonographical monitoring can be recommended.

Primary pulmonary hypertension is a rare, incurable, and progressive disease. When it is associated with pregnancy, the mortality rises to > 50%. We report a patient who was diagnosed with severe pulmonary hypertension of unknown cause in the twenty-second week of gestation. She was treated with an oral calcium-channel blocker and low-molecular-weight heparin and underwent delivery by cesarean section with good maternal and fetal outcome. Patients with severe pulmonary hypertension should, however, avoid pregnancy because of the high mortality, although cases have been reported with positive outcome.

The cervix uteri is of greatest importance for the environment of the fetus. The sonographic imaging of the cervix uteri can be done by transabdominal, perineal and transvaginal route. Each of these methods are associated with specific advantages and disadvantages. During the time of gestation the cervix uteri can be measured sonographically concerning the length, the thickness, the width of the cervical canal and in addition the diameter of the internal and the external os. At the beginning of labour the cervix shows a transformation: a shortening with an increase of thickness. The phase of contraction is followed by a phase of reformation. Individual formations of the cervix regarding the a premature opening of the internal os or the external os could be demonstrable without clinical symptoms. By W. Eppel a score-like formula "Incompetence-Factor" was described for a quantification of these measurements.

In a historical review the situation in obstetrics was shown in the last 3 decades. Compound-scans and "real-time-scan" were the fundamental instruments for the first sonographical diagnosis and changes in clinical practice. The demonstration of the foetal body and organs allows numerous measurements of length, areas, and volumes. Signs of foetal vital functions were studied in different aspects. Doppler-flow-measurements in different parts of the foetal circulatory system had brought to light new information. In future especially colour-coded flow measurement will show signs of foetal life such as drinking, vomiting, and urinating and will enable us to study these functions of foetal life.

In a prospective study of 97 uncomplicated twin pregnancies, vaginosonographic cervix measurements of length, thickness and width of the internal os were performed. Furthermore, a group of 113 uncomplicated primipara was measured by vaginosonography. The twin pregnancies were examined sonographically at 4-5 week intervals between the 14th and 34th week of gestation. The results of the measurements were correlated between these two groups in accordance with duration of pregnancy and the number of deliveries. The results showed in general, that the cervical length of multipara-multiple pregnancy is longer than in the primipara-multiple pregnancy. Between the 13th and 17th week of gestation the cervix of primipara showed a length of 48.1 +/- 2.1 mm, the multipara twins showed a length of 52.3 +/- 3.4 mm. Between the 18th and 22nd gestational week, the primipara showed a cervical length of 49.4 +/- 3.6 mm and the multipara a length of 49.6 +/- 2.6 mm. In the 23rd to 27th week, the primipara had a cervical length of 39.4 +/- 2.4 mm, the multipara of 49.3 +/- 3.7 mm. From the 28th to 33rd week, cervical length was reduced in primipara to 31.2 +/- 2.9 mm, and in multipara to 42.7 +/- 5.1 mm. In the normal group of multipara, the cervical length was slightly longer. The assessment of cervical thickness showed the widest cervices in multipara gemini followed by the primipara gemini, the smallest cervices were found in primipara-single pregnancies.(ABSTRACT TRUNCATED AT 250 WORDS)

In a retrospective study the results of vagino- and colour flow Doppler sonography of 23 tubal pregnancies verified by surgery were documented. Due to the neovascularisation in the trophoblast tissue the vascular impedance was elevated in all cases. The mean value of all pulsatility indices was 0.85 +/- 0.2. The direct signs of tubal pregnancy were seen in only 20 cases with vaginosonography alone. The combination of vagino- and colour flow Doppler sonography offers the chance of an earlier detection (5th week of pregnancy) of a tubal pregnancy.

An invasive mole in an ectopic pregnancy was diagnosed in the 16th week post amenorrhoea by transvaginal colour flow mapping. Colour flow mapping was the only noninvasive method used to verify the diagnosis. In this case the serum level of human chorionic gonadotropin (HCG) was very low (0.196 IU/ml) and subjective symptoms and uterine bleeding were absent.

In this study it was tried to demonstrate the involution of the puerperal uterus vaginosonographically. A collective of 54 patients with uncomplicated delivery and afebrile, inconspicuous puerperium was vaginosonographically examined on the 1st day postpartum and also 6 weeks post partum. To describe the uterus in its whole entity on the 1st day post partum an abdominal sonography was carried out too. The vaginosonographic examinations showed on the 1st day post partum an average cervical length of 40.7 +/- 8.4 mm, a width of 31.2 +/- 4.0 mm and an internal os of 5.6 +/- 3.0 mm. The width of the lower uterine segment was 15.7 +/- 7.7 mm. The control examination after 6 weeks result in a cervical length of 31.2 +/- 4.0 mm, a width of 28.2 +/- 3.9 mm and an internal os of 3.1 +/- 1.1 mm. The reformation of cervix occurs rapidly and can be seen even on the first day post partum.

Questionnaires were sent to all female members (n = 60) of the Austrian Funboard Association (funboard = the most athletic windsurfing class). They included questions about the menstrual cycle, physical capacity, libido and performance dependent on the particular cycle phase. There was no significant libido or capacity peak, neither for the windsurfers nor for a normal collective (n = 100); on the other hand there was an evident low during menstruation. A mean length of the menstrual cycle of 26.5 +/- 2.8 days and a bleeding time of 4.4 +/- 1.2 days were found, while metrorrhaghia and dysmenorrhea were less frequent than in the normal collective. One reason for these findings could be that physical activity reduces dysmenorrhea.
