Background: Over the last two decades, the epidemiology, treatment strategy and mortality rate for congenital diaphragmatic hernia have changed.

Objectives: To retrospectively analyze our experience with CDH[1] of the last 22 years.

Methods: We reviewed the charts of all infants suffering from CDH between 1985 and 2007. Prenatal and maternal as well as perinatal and neonatal data were collected, including outcome parameters. The 71 infants that we identified were divided them into two historical groups: from 1985 to 1995 (group 1, 123 patients) and from 1996 to 2007 (group 2, 45 patients).

Results: We found an increase in the incidence of prenatal diagnosis and a subsequent significant decrease in gestational age at diagnosis in group 2 (25 weeks gestation, compared with 30 weeks gestation in group 1, P = 0.018). In addition, we noted a trend toward a reduced number of infants with right-sided hernia and associated cardiac anomalies. The timing to post-delivery surgery was significantly longer in group 2 (20 hours in group 1 vs. 53 hours in group 2, P < 0.001). A significant reduction in postoperative mortality was demonstrated in group 2 compared with group 1 (13.5% vs. 38.7% respectively, P = 0.04),

Conclusion: Our data suggest a higher survival rate for operated infants in group 1 during the last decade, probably due to changes in preoperative methods of treatment as well as later surgery timing compared to group 1. We speculate that today’s cases of congenital diaphragmatic hernia are probably milder than in the past due to earlier and more detailed prenatal diagnosis and subsequent termination of pregnancies for the more severe forms of the disorder. 

The frequency of pregnancy-associated breast cancer, a rare but serious occurrence, may increase in light of the secular trends for lower parity in general and for an older age at first full-term delivery in particular. Data on PABC[1] in individuals who are at high risk for breast cancer are limited. A computerized search of PUBMED showed that the reported incidence of PABC is 1:3000 pregnancies; it is often diagnosed at an advanced stage and its prognosis is inferior compared to non-PABC. Carriers of mutations in the genes BRCA1/2 may present a specific high risk group for PABC especially at younger ages. Women treated with fertility treatment drugs may be at a higher risk for PABC as well.  

Background: Women frequently suffer perineal trauma while giving birth. Interventions to increase the possibility for an intact perineum are needed.

Objectives: To evaluate the effectiveness of antenatal perineal massage in increasing the likelihood of delivering with an intact perineum.

Methods: This single blinded prospective controlled trial included 234 nulliparous women with a singleton fetus. Women allocated to the study group were instructed to practice a 10 minute perineal massage daily from the 34th week of gestation until delivery. Primary outcome measures included the episiotomy rate; first, second, third and fourth-degree perineal tear rates; and intact perineum. Secondary outcomes were related to specific tear locations and the amount of suture material required for repair.

Results: Episiotomy rates, overall spontaneous tears and intact perineum rates were similar in the study and control groups. Women in the massage group had slightly lower rates of first-degree tears (73.3% νs. 78.9%, P = 0.39) and slightly higher rates of second-degree tears (26.7% νs. 19.3%, P = 0.39), although both of these outcomes did not reach statistical significance. The rates of anterior perineal tears were significantly higher in the massage group (9.5% vs. 3%, P = 0.05), whereas internal lateral tears rates were slightly lower but without statistical significance (11.5% νs.13.1%, P = 0.44).

Conclusions: The practice of antenatal perineal massage showed neither a protective nor a detrimental significant effect on the occurrence of perineal trauma.
 

Background: Intrapartum risk is based mainly on obstetric history, which is lacking in primiparous women.

Objectives: To ascertain whether the traditional known risk of primiparity is an independent variable for both maternal and neonatal outcome.

Methods: All women admitted to labor during March-April 2002 were canvassed for eligibility for participation in the study based on an obstetric risk scoring system developed and validated for our population. During the study period, 1473 women presented for delivery. Of these, 298 women (20%) were eligible according to the exclusion criteria as "low risk" parturients: 135 (45%) were primiparous and 163 (55%) were multiparous (2–5 births).

Results: After correction for significant confounding factors, primiparity was revealed as an independent significant risk factor for instrumental delivery (odds ratio 15.5, 95%confidence interval 1.88–125) and for early postpartum hemorrhage (OR[1] 5.6, 95%CI[2] 1.9–16.6).

Conclusions: This study highlights early postpartum hemorrhage as a significant risk for primiparous women, independent of mode of delivery, and also confirms previous reports of maternal complications requiring transfer from birth centers/home deliveries to tertiary centers.

Background: The measurement of maternal serum human chorionic gonadotropin as a predictor of fetuses with Down syndrome has been in use since 1987.

Objectives: To determine the correlation between extremely high levels of hCG[1] at mid-gestation and maternal and fetal complications.

Methods: The study group consisted of 75 pregnant women with isolated high levels of hCG (> 4 MOM) at mid-gestation, and the control group comprised 75 randomly selected women with normal hCG levels (as well as normal alpha-fetoprotein and unconjugated estriol levels). The data collected included demographic details, fetal anomalies, chromosomal aberrations, pregnancy complications, and results of neonatal tests.

Results: There was a significant increase in the frequency of fetal anomalies (detected by ultrasound), low birth weight and neonatal complications in the study group. We also found an increased rate of fetal/neonatal loss proportional to the increasing levels of hCG (up to 30% in levels exceeding 7 MOM).

Conclusion: Our study demonstrated an increased frequency of obstetric complications that was closely associated with raised hCG levels. The study also raises questions about the accuracy of the Down syndrome probability equation in the presence of extremely high levels of hCG where data on the frequency of Down syndrome is severely limited.
