Fetal imaging and therapy for CDH-Current status.

In congenital diaphragmatic hernia (CDH), herniation of the abdominal organs into the fetal chest causes pulmonary hypoplasia and pulmonary hypertension, the main causes of neonatal mortality. As antenatal ultrasound screening improves, the risk of postnatal death can now be better predicted, allowing for the identification of fetuses that might most benefit from a prenatal intervention. Fetoscopic tracheal occlusion is being evaluated in a large international randomized controlled trial.

Antenatal predictors of outcome in prenatally diagnosed congenital diaphragmatic hernia (CDH).

Background: Pulmonary hypoplasia is the main cause of mortality in isolated congenital diaphragmatic hernia (CDH) and its prediction is paramount when counseling parents. We sought to identify antenatal parameters that predicted neonatal mortality in CDH.

Method: Search was conducted in MEDLINE, EMBASE, Cochrane Database of Systematic reviews, PubMed, Scopus, and Web of Science on the ability of lung-to-head ratio (LHR), observed-to-expected LHR (o/e LHR), total fetal lung volume (TFLV), o/e TFLV, percentage predicted lung volume (PPLV) and degree of liver herniation to predict neonatal morbidity and mortality in fetuses with CDH.

Perinatal and maternal outcomes in critically ill obstetrics patients with pandemic H1N1 Influenza A.

Background: During the influenza pandemic of spring 2009, Manitoba had a disproportionate number of pregnant women who became critically ill. Information about these cases will be useful to help us understand the potential impact of future outbreaks and review critical illness in pregnancy.

Methods: We describe the clinical details of six critically ill pregnant women with pandemic H1N1 2009 influenza virus admitted to two ICUs in Manitoba between March 1 and August 31, 2009.
