Parental IBD and Long-term Health Outcomes in the Offspring.

Inflamm Bowel Dis 2019 Jan 8. Epub 2019 Jan 8.

Center for Clinical Epidemiology, Odense University Hospital and Research Unit of Clinical Epidemiology, Odense Denmark.

For decades, the research on reproductive consequences in women with inflammatory bowel disease (IBD) has focused on short-term outcomes, including adverse pregnancy outcomes (eg, abruptio placenta, placenta previa, preeclampsia/eclampsia) and adverse birth outcomes (eg, small for gestational age, preterm birth, and congenital malformations). The long-term health outcomes of the children of parents with IBD have been studied to a much lesser extent, and there is a critical research gap in understanding the influence of parental IBD on long-term outcomes. In this review, we propose the reasons for this lack of evidence and highlight the weakest areas of the research on the impact of parental IBD on offspring health. Read More

Harefuah 2018 Dec;157(12):783-786

Department of Gynecology and Obstetrics, Rambam Health Care Campus, affiliated with Technion-Israel Institute of Technology, Haifa, Israel.

Introduction: Smoking during pregnancy is a public health problem because of the many adverse effects associated with it. These include intrauterine growth restriction, placenta previa, abruptio placentae, decreased maternal thyroid function, preterm premature rupture of membranes, low birth weight, perinatal mortality, and ectopic pregnancy. An estimated 5-8% of pre-term deliveries, 13-19% of term deliveries of infants with low birth weight, 23-34% cases of sudden infant death syndrome (SIDS), and 5-7% of preterm-related infant deaths can be attributed to prenatal maternal smoking.

Placenta Accreta: A Spectrum of Predictable Risk, Diagnosis, and Morbidity.

Am J Perinatol 2018 Nov 30. Epub 2018 Nov 30.

Department of Obstetrics, Gynecology, and Reproductive Sciences, Yale School of Medicine, New Haven, Connecticut.

Objective:  Placenta accreta is a feared pathology, in part, because prenatal diagnosis is imperfect. It is not known whether clinical risk factors or sonographic features equally predict the entire graded pathological spectrum of placental overinvasion disease nor whether clinical outcomes differ along the spectrum.

Study Design:  We conducted a mixed methods retrospective study of a cohort of women screened sonographically for placenta accreta, cross-referenced against cases identified by pathological diagnosis ( = 416). Read More

Blunt dissection technique with finger and vessel skeletonization in the posterior vesical wall for abnormally invasive placenta previa.

J Matern Fetal Neonatal Med 2018 Nov 28:1-71. Epub 2018 Nov 28.

a Department of Obstetrics and Gynecology , Gaziantep University , School of Medicine , Gaziantep , Turkey.

Purpose: This study described a new technique to minimize the bleeding resulted from aberrant engorged vessels and unintended bladder injury in cases with abnormally invaded placenta adjacent to posterior bladder wall at cesarean hysterectomy.

Methods: After filling the bladder with 300 ml saline aberrant engorged vessels were identified and skeletonized between lower uterine segment and bladder with blunt dissection by index finger down to the distal end point of cervix.

Results: This technique has beneficial effect on preventing bladder injury and reduces bleeding resulting from the aberrant vessels and the communicating vessels that were based around the vesicouterine fold and the cervico-vesical interface (in the lower part of the cervix); respectively.

A prospective evaluation and management of different types of placenta praevia using parallel vertical compression suture to preserve uterus.

Medicine (Baltimore) 2018 Nov;97(46):e13253

The rising tendency of cesarean sections will lead invariably to more complications such as placenta praevia. The aim of our study was to evaluate the utility of parallel vertical compression suture to preserve uterus in cases of placenta praevia, and to propose a rational approach of these problematic cases, according to their grade of myometrial invasion.We prospectively included 95 consecutive cases diagnosed with placenta praevia (group1 [Gr1]) where we used parallel compression suture and compared to retrospectively analyzed 100 consecutive cases managed without using this technique (group 2 [Gr2]).
