BackgroundThe aim of the study was to investigate the accuracy of ultrasound-derived estimated fetal weight (EFW) and to determine its impact on management and outcome of delivery.MethodsIn this single-center cohort analysis, women with a singleton term pregnancy in the beginning stages of labor were included. Women with immediately antepartum EFW (N = 492) were compared to women without ultrasound (N = 515).ResultsEFW was correct (deviation from birth weight ≤ 10%) in 72.2% (355/492) of patients with fetal biometry; 19.7% (97/492) were underestimated, and 8.1% (40/492) were overestimated. Newborns with a lower birth weight were more frequently overestimated, and newborns with higher birth weight were more frequently underestimated. The mean difference between EFW and real birth weight was − 114.5 g (standard deviation ±313 g, 95% confidence interval 87.1–142.0). The rate of non-reassuring fetal heart tracing (9.8% vs. 1.9%, P < 0.001) and of caesarean delivery (9.1% vs. 5.0%, P = 0.013) was higher in women with EFW. Overestimation was associated with an increased risk for delivery by caesarean section (odds ratio 2.80; 95% confidence interval 1.2–6.5, P = 0.017). After adjustment, EFW remained associated with increased non-reassuring fetal heart tracing (odds ratio 4.73; 95% confidence interval 2.3–9.6) and caesarean delivery (odds ratio 1.86; 95% confidence interval 1.1–3.1). The incidence of perineal tears of grade 3/4, shoulder dystocia, postnatal depression and neonatal acidosis did not differ between groups.ConclusionsAntepartum ultrasound-derived EFW does not improve maternal and fetal outcome and is therefore not recommended.

Spontaneous ovarian hyperstimulation syndrome (OHSS) is an extremely rare event. Normally OHSS is seen in the context of IVF. In 2003 a mutation of the FSH receptor (FSHR D567N) was identified for the first time as a cause of spontaneous OHSS. In most FSHR mutations, a hypersensitivity to human chorionic gonadotrophin (HCG) or thyroid-stimulating hormone (TSH) is described. This clinical case presents for the first time two occurrences of spontaneous OHSS in a single woman with a FSHR mutation and two different entities. Pathophysiology of both pregnancies was completely different. During the first pregnancy, elevated HCG and androgen concentrations led to spontaneous OHSS and finally to miscarriage. The second pregnancy with spontaneous OHSS was dominated by a latent hypothyroidism and normal HCG concentrations and ended in a delivery of a healthy female newborn. Due to the unusual courses of the pregnancies, the study looked for a mutation in the FSHR and surprisingly identified the same mutation previously described. This report confirms for the first time the in-vitro findings in a single clinical case that TSH as well as HCG leads to spontaneous OHSS in patients with FSHR D567N mutation. Hypothyroidism has to be treated or ruled out.

BackgroundWomen with bilateral abnormal uterine artery Doppler velocimetry (UtADV) are at increased risk for an adverse pregnancy outcome. This study aimed to determine if additional assessment of midtrimester angiogenic factors improves the predictive accuracy of Doppler results for various outcome parameters.MethodsWomen with a bilateral abnormal UtADV, which was defined as a postsystolic incision and/or an increased pulsatility index greater than the 95th centile, and a singleton pregnancy were prospectively recruited between 19 + 0 and 26 + 6 weeks of gestation. Maternal serum levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFLT-1) were measured with a fully automated immunoassay and their ratio was calculated.ResultsAngiogenic factors could predict the development of preeclampsia (PE), as well as induced delivery at <34 weeks of gestation, but failed to predict the development of normotensive intrauterine growth restriction. Twelve (24.0%) of the 50 recruited women developed PE. Nine of these patients had early-onset disease (<34 + 0 weeks). Six (12.0%) patients were delivered at <34 + 0 weeks. The most useful test results in the prediction of PE and induced delivery at <34 + 0 weeks were observed using the sFLT-1/PlGF >95th centile ratio with a sensitivity, specificity, positive predictive value, and negative predictive value (NPV) of 66.7%, 89.5%, 66.7%, and 89.5% for PE, and 85.7%, 86.1%, 50.1%, and 97.4% for induced delivery, respectively. Positive and negative likelihood ratios were 6.33 (95% CI 2.31–17.38) and 0.37 (95% CI 0.17–0.84) for PE, and 6.14 (95% CI 2.76–13.69) and 0.17 (0.03–1.02) for induced delivery, respectively. Corresponding odds ratios were 17.0 (95% CI 3.5–83.0) and 37.0 (95% CI 3.8–363.9), respectively.ConclusionsMeasurement of angiogenic factors improves the specificity of an abnormal UtADV for prediction of PE. Compared with prediction of PE an abnormal sFLT-1/PlGF ratio revealed higher sensitivity for prediction of induced delivery at <34 + 0 weeks. The NPV of 97% will help to reassure most patients with an abnormal UtADV and a normal sFLT-1/PlGF ratio.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2393-14-292) contains supplementary material, which is available to authorized users.

In a major city without specialised outpatient ENT emergency system patient are attracted regularly to present at the University ENT emergency unit. This means a significant work load for the resident on duty. Most of the patients have ENT diseases treatable with this one and last patient contact. On the other hand, the hospital recruits an important amount of patients for inpatient treatment through the emergency unit.

The PM is a key component that viruses have to cope with. It is a barrier for infection and egress and is critically involved in antiviral immune signaling.
