Trisomy 13, trisomy 18, and triploidy belong to the chromosomal abnormalities which are compatible with life, but which are also associated with a high rate of spontaneous abortion, intrauterine death, and a short life span. This study was conducted to analyze natural outcome after prenatal diagnosis of these disorders. Between January 1, 1999 and December 31, 2009, we investigated all amniocenteses and chorionic villus biopsies carried out at our department. All cases with fetal diagnosis of triploidy, trisomy 13, and 18 were analyzed, with a focus on cases with natural outcome. Overall, 83 (78%) cases of pregnancy termination and 24 (22%) patients with natural outcome (NO) were identified. The NO group included 15 cases of trisomy 18, six cases of triploidy, and three cases of trisomy 13. No case of triploidy was born alive. The live birth rate was 13% for trisomy 18 and 33% for trisomy 13. The three live-born infants with trisomy 13 and 18 died early after a maximum of 87 hr postpartum. Our data are consistent with the literature concerning outcome of triploidy, with none or only a few live births. Analyzes of trisomy 13 and 18 indicate a very short postnatal life span. Different study designs and diverse treatment strategies greatly affect the fetal and neonatal outcome of fetuses with triploidy, trisomy 13, and 18. More studies analyzing natural outcome after prenatal diagnosis of these chromosomal abnormalities are needed. Non-termination of these pregnancies remains an option, and specialists advising parents need accurate data for counseling.

BackgroundInternational guidelines recommend that tocolytic therapy be restricted to a single 48-h application. However, multiple cycles of tocolytic therapy and maintenance therapy that exceeds 48 h appear to play a role in daily clinical practice. We aimed to evaluate current trends in clinical practice with respect to treatment with tocolytic agents and to identify differences between evidence-based recommendations and daily clinical practice in Austria.MethodsA prospective multicenter registry study was conducted from October 2013 through April 2015 in ten obstetrical departments in Austria. Women ≥18 years of age who received tocolytic therapy following a diagnosis of threatened preterm birth were included, and details were obtained regarding clinical characteristics, tocolytic therapy, and pregnancy outcome.ResultsA total of 309 women were included. We observed a median of 2 cycles of tocolytic therapy per patient (IQR 1–3) with a median duration of 2 days per cycle (IQR 2–5). Repeat tocolysis was administered in 41.7% of women, resulting in up to six tocolysis cycles; moreover, 40.8% of the first tocolysis cycles were maintenance tocolysis (i.e., longer than 48 h). Only 25.6% of women received one single 48-h tocolysis cycle in which they received antenatal corticosteroids for fetal lung maturation in accordance evidence-based recommendations.ConclusionsHere, we report a clear disparity between evidence-based recommendations and daily practice with respect to tocolysis. We believe that the general practice of prescribing tocolytic therapy must be revisited. Furthermore, our findings highlight the need for contemporary studies designed to investigate the effectiveness of performing maintenance and/or repetitive tocolysis treatment.Electronic supplementary materialThe online version of this article (10.1186/s12884-018-2078-5) contains supplementary material, which is available to authorized users.

Background: Soluble FMS-like Tyrosine Kinase 1 (sFlt-1) and placental growth factor (PlGF) have been reported to be highly predictive several weeks before the onset of preeclampsia. Objective: To investigate longitudinal changes of serum levels sFlt-1 and PlGF in pregnant women at high risk for the development of preeclampsia and to reveal an impact of aspirin on maternal serum concentrations of sFlt-1 and PlGF. Methods: This was a prospective longitudinal study in 394 women with various risk factors for the development of preeclampsia (chronic hypertension, antiphospholipid syndrome/APS or systemic lupus erythematosus/SLE, thrombophilia, women with a history of preeclampsia, pathologic first trimester screening for preeclampsia) and 68 healthy women. Serum levels of sFlt-1 and PlGF were measured prospectively at 4-week intervals (from gestational weeks 12 until postpartum). Results: The sFlt-1/PlGF ratio was significantly higher in women with an adverse obstetric outcome compared to women with a normal pregnancy, starting between 20 and 24 weeks of gestation. There was no effect of aspirin on sFlt-1/PlGF ratio in women with chronic hypertension, APS/SLE, thrombophilia and controls. The use of aspirin showed a trend towards an improvement of the sFlt-1/PlGF ratio in women with preeclampsia in a previous pregnancy and a significant effect on the sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia. Conclusions: Our findings reveal an impact of aspirin on sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia, strongly supporting its prophylactic use.

SummaryBackgroundCancer-to-cancer metastasis is very rare with less than 50 cases described in literature. This article reports a case of breast cancer with synchronous metastasis to clear cell renal cell cancer.Case descriptionA 79-year-old woman was diagnosed with a bilateral breast carcinoma. Sonographic staging investigation of the abdomen revealed a 6 cm wide expansion of the right kidney. Bilateral mastectomy and nephrectomy of the right kidney was performed. The histology revealed a clear cell renal cell carcinoma and in the center of the tumor a 0.5 cm metastasis of the breast cancer. The patient’s comorbidities and performance status precluded chemotherapy und she received palliative radiotherapy, targeted monoclonal antibody therapy and antihormonal treatment.ConclusionsEven if cancer-to-cancer metastasis is a very rare phenomenon, the simultaneous or consecutive finding of a renal tumor in women with breast cancer should be carefully evaluated.
