Balloon catheter for induction of labor in women with one previous cesarean and an unfavorable cervix.

INTRODUCTION: When women with a previous cesarean section and an unfavorable cervix have an indication for delivery, the choice is to induce labor or to perform a cesarean section. This study aims to assess the effectiveness and safety of a balloon catheter as a method of induction of labor in women with one previous cesarean section and an unfavorable cervix compared with an elective repeat cesarean section. MATERIAL AND METHODS: We performed a prospective cohort study in 51 hospitals in the Netherlands on term women with one previous cesarean section, a live singleton fetus in cephalic position, an unfavorable cervix and an indication for delivery. We recorded obstetric, maternal and neonatal characteristics. We compared the outcome of women who were induced with a balloon catheter with the outcome of women who delivered by elective repeat cesarean section. Main outcomes were maternal and neonatal morbidity. Mode of delivery was a secondary outcome for women who were induced. Adjusted odds ratios (aOR) were calculated using logistic regression, adjusted for potential confounders. RESULTS: Analysis was performed on 993 women who were induced and 321 women who had a repeat cesarean section (August 2011 until September 2012). Among the women who were induced, 560 (56.4%) delivered vaginally and 11 (1.1%) sustained a uterine rupture. Composite adverse maternal outcome (uterine rupture, severe postpartum hemorrhage or postpartum infection) occurred in 73 (7.4%) in the balloon and 14 (4.5%) women in the repeat cesarean section group (aOR 1.58, 95% confidence interval [CI] 0.85-2.96). Composite adverse neonatal outcome (Apgar score <7 at 5 minutes or umbilical pH <7.10) occurred in 57 (5.7%) and 10 (3.2%) neonates, respectively (aOR 1.40, 95% CI 0.87-3.48). Women who were induced had a shorter postpartum admission time (2.0 vs 3.0 days (P < 0.0001)). CONCLUSIONS: In women with a previous cesarean section and a need for delivery, induction of labor with a balloon catheter does not result in a significant increase in adverse maternal and neonatal outcomes as compared with planned cesarean section.

Chorionic villous vascularization related to phenotype and genotype in first trimester miscarriages in a recurrent pregnancy loss cohort.

STUDY QUESTION: Is there an association between chorionic villous vascularization, ultrasound findings and corresponding chromosome results in early miscarriage specimens from a cohort of recurrent pregnancy loss patients? SUMMARY ANSWER: We did not find a significant difference in vascularization scores of chorionic villi between embryonic, yolk sac or empty sac miscarriages, or between euploid and noneuploid miscarriages. WHAT IS KNOWN ALREADY: At least half of first trimester miscarriages are due to embryopathogenesis associated with chromosome errors and/or major congenital anomalies, resulting in an empty sac, a yolk sac or an embryonic miscarriage. Absent and decreased chorionic villous vascularization is usually present in these pregnancies. STUDY DESIGN, SIZE, DURATION: For this retrospective study, 60 hematoxylin and eosin slides of miscarriage tissue of less than 10 weeks gestational age were collected from an academic institution. All patients were seen in consultation between July 2004 and October 2009. PARTICIPANTS, SETTING, METHODS: Chorionic villous vascularization was determined using a previously published classification. The results were validated and compared with the ultrasound findings and corresponding chromosome results. MAIN RESULTS AND THE ROLE OF CHANCE: There were 53 embryonic miscarriages, 5 yolk sac miscarriages and 2 empty sac miscarriages. Chromosome results were obtained in 59 of the 60 miscarriages; 37.3% were euploid and 62.7% were noneuploid. Validation of the vascularization score between observers was reasonable to good (Kappa 0.47-0.76), and 59% of the cases were classified as avascular. The vascularization score did not differ between euploid or noneuploid miscarriages, or between embryonic, yolk sac or empty sac miscarriages. Avascular villi were seen more frequently in miscarriages trisomic for chromosome 16, when compared with miscarriages with other trisomies (6 out of 7 versus 8 out of 22, P = 0.04). LIMITATIONS, REASONS FOR CAUTION: Unfortunately, the number of samples in the study was limited. WIDER IMPLICATIONS OF THE FINDINGS: Avascular villi may indicate abnormal early placentation as a part of embryopathogenesis. Further study is warranted to determine whether a genetic cause can be found to explain these results.

Can ultrasound be the diagnostic modality to diagnosis anti-N-methyl-D-aspartate receptor encephalitis?

Anti-N-methyl-D-aspartate receptor encephalitis is an auto-immune paraneoplastic disease of the limbic system. This syndrome may present itself as a range of psychiatric, neurological and autonomic features. It is associated with long-term morbidity and mortality. The syndrome is associated with ovarian teratoma affecting mainly young females. If the syndrome is identified at an early stage, then a good prognosis is expected. In this case report, the ultrasound performed by an experienced and competent operator was more sensitive than MRI in diagnosing a small ovarian teratoma. Following the removal of the teratoma and with appropriate immunotherapy the patient's condition improved. In the clinical suspicion of anti-A-methyl-D-aspartate receptor encephalitis, the first modality of choice should be an ultrasound of the ovaria performed by an experienced and competent operator.

[Hyperthyroidism and an unexpected molar pregnancy]. / Hyperthyreoïdie en een onverwachte molazwangerschap.

BACKGROUND: A molar pregnancy is a rare complication of (non-viable) pregnancy and produces high levels of hCG-hormone. hCG has characteristics similar to TSH, and therefore (severe) hyperthyroidism can occur. The incidence of molar pregnancy is approximately 1 in 1000-1500 pregnancies. CASE DESCRIPTION: A 23-year-old woman had complaints of discomfort, nausea and vomiting. A urine pregnancy test was negative and laboratory tests showed a severe hyperthyroidism. After referral a molar pregnancy was diagnosed (hCG 1.7 million IU/L). She was treated by curettage. hCG levels insufficiently decreased in the following weeks, and gestational trophoblastic neoplasia was diagnosed. She needed several courses of methotrexate after which she completely recovered. CONCLUSION: Severe hyperthyreoidism can be caused by a molar pregnancy. A urine pregnancy test can be negative because of too high hCG-levels, also known as the hook effect. Early recognition and treatment are very important because of the risk of severe complications.

Cardiovascular disease risk in women with a history of spontaneous preterm delivery: A systematic review and meta-analysis.

BACKGROUND: Increasing evidence suggests a relation between having had spontaneous preterm delivery and cardiovascular disease in the future. We performed a systematic review and meta-analysis to assess the relation between a history of spontaneous preterm delivery and risk of ischaemic heart disease (IHD), stroke or overall cardiovascular disease (CVD). METHODS: We carried out a systematic search in Medline (from 1966 to 17 July 2014) and Embase (from 1980 to 17 July 2014). We included studies with a cohort design assessing the relation between spontaneous preterm delivery and fatal or nonfatal IHD, stroke, or overall CVD. IHD, stroke and CVD were assessed through linkage with national registries. Hazard ratios (HRs) were pooled using a random-effects model. RESULTS: Of the 10 cohort studies included; sample sizes ranged from 3706 to 923,686 women and follow-up ranged from 12-35 years. Spontaneous preterm delivery was related to an increased risk of developing or dying from IHD (HR 1.38, 95% confidence interval (CI) 1.22-1.57), stroke (HR 1.71, 95% CI 1.53-1.91) and overall CVD (relative risk (HR) 2.01, 95% CI 1.52-2.65). All studies found a positive effect, although substantial between-study heterogeneity was found for IHD and CVD. CONCLUSION: Spontaneous preterm delivery is an independent risk factor for the development of IHD, stroke and overall CVD.

Cardiovascular risk management after reproductive and pregnancy-related disorders: A Dutch multidisciplinary evidence-based guideline.

BACKGROUND: In the past decades evidence has accumulated that women with reproductive and pregnancy-related disorders are at increased risk of developing cardiovascular disease (CVD) in the future. Up to now there is no standardised follow-up of these women becausee guidelines on cardiovascular risk management for this group are lacking. However, early identification of high-risk populations followed by prevention and treatment of CVD risk factors has the potential to reduce CVD incidence. Therefore, the Dutch Society of Obstetrics and Gynaecology initiated a multidisciplinary working group to develop a guideline for cardiovascular risk management after reproductive and pregnancy-related disorders. METHODS: The guideline addresses the cardiovascular risk consequences of gestational hypertension, preeclampsia, preterm delivery, small-for-gestational-age infant, recurrent miscarriage, polycystic ovary syndrome and premature ovarian insufficiency. The best available evidence on these topics was captured by systematic review. Recommendations for clinical practice were formulated based on the evidence and consensus of expert opinion. The Dutch societies of gynaecologists, cardiologists, vascular internists, radiologists and general practitioners reviewed the guideline to ensure support for implementation in clinical practice. RESULTS: For all reproductive and pregnancy-related disorders a moderate increased relative risk was found for overall CVD, except for preeclampsia (relative risk 2.15, 95% confidence interval 1.76-2.61). CONCLUSION: Based on the current available evidence, follow-up is only recommended for women with a history of preeclampsia. For all reproductive and pregnancy-related disorders optimisation of modifiable cardiovascular risk factors is recommended to reduce the risk of future CVD.
