Background: Fetal macrosomia is a risk factor for operative vaginal delivery (VD), shoulder dystocia, obstructed labor, and cesarean section (CS). Induction of labor (IOL) may decrease these risks but also leads to longer labor, increasing the risk of CS. No data exist regarding the optimal method of IOL in macrosomic fetuses, and most studies are limited to the efficacy of medical induction.

Objective: To compare medical and mechanical IOL in macrocosmic fetuses.

Methods: This retrospective case-control study included pregnant women who underwent IOL and delivered macrosomic neonates at a tertiary center between 2010 and 2020.

Women with non-cephalic presentation, prior CS, and multiple pregnancies were excluded. The primary outcome was the mode of delivery. Secondary outcomes included neonatal and maternal complications.

Results: A total of 247 women were included in the study, 188 underwent cervical ripening with prostaglandin E2 (PGE2) regimens and 59 with a double-balloon catheter. Higher rates of prior deliveries over 4000 grams and Oxytocin use during delivery were found in the mechanical induction group. No other clinically significant differences in demographic or clinical characteristics were identified. There were no statistically significant differences in the rates of VD or CS between the groups. The indications for CS were similar. Maternal and neonatal secondary outcomes were comparable.

Conclusion: PGE2 vaginal regimens and double catheter balloons are safe and effective methods for cervical ripening during IOL in term pregnancies with macrosomic neonates. The choice of cervical ripening method did not impact the mode of delivery or maternal and neonatal outcomes.

Background: The World Health Organization classified coronavirus disease-19 (COVID-19) as a pandemic and recommends strict restrictions regarding most aspects of daily activities.

Objectives: To evaluate whether the pandemic has changed the prenatal care and pregnancy outcome in pregnant women without COVID-19.

Methods: The authors conducted a cross-sectional study to describe changes in outpatient clinic visits and to compare the rates of cesarean and instrumental deliveries between two periods of time: March–April 2020 (during the COVID-19 outbreak) with March–April of the preceding year, 2019.

Results: During the COVID-19 outbreak, visits to obstetric triage, gynecologic triage, high-risk clinic, and ultrasound units decreased by 36.4%, 34.7%, 32.8%, and 18.1%, respectively. The medical center experienced a 17.8% drop in the total number of births (610 births) compared with March and April 2019 (742 births). During the outbreak women were more likely to be nulliparous (33.3% vs. 27.6%, P = 0.02) and present with hypertensive disorders during pregnancy (7.5% vs. 4%, P = 0.005) or gestational diabetes (13% vs. 10%, P = 0.03). More epidural analgesia was used (83.1% vs. 77.1%, P = 0.006). There were more operative vaginal deliveries during the outbreak (16.7% vs. 6.8%, P = 0.01). All other maternal and neonatal outcomes were comparable between the two periods.

Conclusions: The medical facility experienced a major decline in all aspects of the routine obstetrics activities during the time of the pandemic. The higher rate of operative vaginal deliveries among nulliparous may be associated with the pandemic effect on the rate of high-risk patients

Background: Unilateral renal agenesis is a rare finding. There are no large-scale studies reporting this finding in early pregnancy.

Objectives: To evaluate the incidence of unilateral renal agenesis (URA) and of associated anomalies diagnosed by early prenatal trans-vaginal sonography.

Methods: We performed a retrospective chart review of all 59,382 trans-vaginal scans performed at 14–16 weeks gestation by a single operator at different clinics during the period 1994–2013.

Results: The incidence of URA was 1:1212 (49/59382 cases). Associated anomalies were diagnosed in 22 cases (45%). Renal anomalies were diagnosed in 22.4%. Extra-renal anomalies (with exclusion of a single umbilical artery or nuchal edema as isolated findings) were diagnosed in 24.5%. Ambiguous genitalia were diagnosed in 8.2%.

Conclusions: URA is a rare finding in early trans-vaginal sonography. Associated anomalies are very common and should be sought.

Background: Ptyalism gravidarum (PG) is a condition of hypersalivation that affects pregnant women early in gestation. Symptoms include massive saliva volumes (up to 2 liters per day), swollen salivary glands, sleep deprivation, significant emotional distress, and social difficulties.

Objectives: To examine maternal and fetal characteristics and pregnancy outcomes of patients with PG.

Methods: Patients diagnosed with PG in our clinic during the years 2001–2016 were identified and contacted. Demographic data were extracted from patient charts and clinical and outcome data was collected via telephone interviews.

Results: The incidence of PG was 1/963 (0.09%) in our sample. Eleven out of 22 women (40%) with PG were also diagnosed with hyperemesis gravidarum. Fetal gender did not increase the risk. Of the mothers presenting with PG, 37% had a positive family history for this condition. There was no associated increase in the rate of fetal or maternal complications. Two women reported a resolution of the symptoms immediately following hypnosis with acupuncture treatment.

Conclusions: Although PG represents an unpleasant mental and physical condition, it does not pose any specific risk to the health of the mother or increase adverse perinatal outcomes for the fetus. Alternative medicine could play a role in the treatment of PG.

Background: Cytomegalovirus (CMV) infection during pregnancy is the most common cause of intrauterine infection, and is a common cause of sensorineural hearing loss and mental retardation. 

Objectives: To evaluate trends in amniocentesis and pregnancy outcome in women with suspected cytomegalovirus (CMV) infection during the first trimester.

Methods: All blood tests for CMV immunoglobulin M (IgM) done between 2008 and 2009 on pregnant women who were enrolled in the Maccabi Healthcare Services were retrieved from laboratory database. Immunoglobulin G (IgG) avidity was measured and women were classified according to the risk of acquiring CMV infection. For each patient, performance of amniocentesis and whether pregnancy came to term were recorded.

Results: Of 109,439 pregnant women evaluated during the study period, 76,712 (70.1%) were tested for CMV IgM, and 792 (1.03%) were found to be positive. Among women with positive IgM, only 205 (25.9%) underwent amniocentesis. When compared with women with negative CMV IgM, the rate of pregnancy cessation was doubled in women with positive CMV IgM (28.3% vs. 14.3%, P < 0.05) and mostly elevated in women with a high risk of acquiring CMV (42.3% pregnancy cessation). Among women with positive CMV IgM, those who did not undergo amniocentesis were more likely to abort than those who performed amniocentesis (35.6% vs. 7.3%, P < 0.05). 

Conclusions: More women with suspected CMV infection during the first trimester of pregnancy aborted before all means of detection were utilized to rule out or confirm fetal infection with CMV.
