Retrospective Cohort Study of Cervical Pessary Use in Women with Short Cervix at Risk of Preterm Delivery.

Objective: A paucity of effective interventions exists for the prevention of preterm birth (PTB). Renewed interest has focused on cervical pessaries, which have the benefits of being inexpensive, nonsurgical, and easily inserted and removed. In this study, we aim to describe our experience with this device in a Canadian tertiary care centre.

Accuracy of Prenatal Ultrasound in Detecting Growth Abnormalities in Triplets: A Retrospective Cohort Study.

Significant management decisions in triplet pregnancies are made based mainly on ultrasound measurements of fetal growth, although there is a paucity of data examining the accuracy of fetal weight measurements in these gestations. To evaluate accuracy of prenatal ultrasound to diagnose growth abnormalities (intrauterine growth restriction, severe growth discordance) in triplet pregnancies, a retrospective cohort study of 78 triplet pregnancies (234 fetuses) delivered at a single tertiary hospital from January 2004 to May 2015 was performed. Growth percentiles from the last ultrasound were derived from estimated fetal weight using Hadlock's formula for each triplet.

Mise à jour technique sur la physiologie et l'évaluation du liquide amniotique.

Objectif: RéSULTATS: SOURCES DES DONNéES PROBANTES: Nous avons effectué une recherche sur MEDLINE et Kfinder pour trouver des articles pertinents, puis avons examiné les bibliographies des articles retenus, notamment des revues Cochrane et des articles de revue récents.

Valeurs: Les données recueillies ont été analysées par le Comité d'imagerie diagnostique de la Société des obstétriciens et gynécologues du Canada. Les recommandations ont été classées selon les critères établis par le Groupe d'étude canadien sur les soins de santé préventifs (Tableau 1).

Amniotic Fluid: Technical Update on Physiology and Measurement.

Objective: OUTCOMES: EVIDENCE: A MEDLINE and KFINDER search was used to identify relevant articles, with review of bibliography identified article including Cochrane reviews and recent review articles.

Values: The evidence collected was reviewed by the Diagnostic Imaging Committee of the Society of Obstetricians and Gynecologists of Canada. The recommendations were made according to the guidelines developed by The Canadian Task Force on Preventative Health Care (Table 1).

A Woman With Marfan Syndrome in Pregnancy: Managing High Vascular Risk With Multidisciplinary Care.

Background: Women with connective tissue disorders are at risk for cardiovascular complications during pregnancy, but there are no guidelines for pregnant women with aortic root diameter>45 mm or with rapid aortic widening. We describe the issues of practical significance in the management of pregnancy and delivery in a woman with Marfan syndrome (MFS).

Case: A pregnant woman with MFS presented for tertiary care at 26 weeks' gestation.

Triplet pregnancy: is the mode of conception related to perinatal outcomes?

Many triplets are conceived as a consequence of assisted reproductive technology (ART). Concerns have been raised that triplet pregnancies conceived by ART are more complicated than those conceived spontaneously. The purpose of this study was to evaluate all triplet pregnancies managed over a 12-year period to determine if there were any differences in outcome based on the mode of conception.
