Background: Cases of second trimester pregnancy loss can be treated either pharmacologically or by surgical evacuation. Misoprostol, an E1-prostaglandin analog, is used to facilitate the evacuation of the uterus.

Objectives: To determine the risk factors associated with patients who were treated with five or more repeated doses of misoprostol.

Methods: We conducted a retrospective study of patients treated with vaginal misoprostol at our institution between December 2016 and October 2021 for second trimester pregnancy loss.

Results: In total, 114 patients were eligible for analysis; 83 were treated with < 5 doses and 31 with ≥ 5. We recorded each case in which repeated doses were administered, irrespective of predetermined conditions such as gravidity, parity, maternal age, or gestational age. Moreover, cases of five or more misoprostol dosing were not associated with an increased complications rate, except for the increased duration of hospitalization (3.1 vs. 2.2 days, P-value < 0.01).

Conclusions: Repeated dosing could not be predicted before treatment among those treated with vaginally administered misoprostol for second trimester pregnancy loss. However, low complication rates of repeated dosing may reassure both physicians and patients regarding safety, efficacy, and future fertility.

Background: Sperm banks initially focused on providing sperm donation (SD) to heterosexual couples grappling with severe male infertility. Notable advancements in fertility treatments and sociological trends have broadened the scope of SD toward single women and same sex female couples.

Objectives: To evaluate SD recipient characteristics over the last three decades in Israel according to demographic parameters.

Methods: This retrospective cohort study included 5489 women who received SD between January 1992 and December 2021 from a tertiary referral center. We divided the overall period into six groups of five years each. A comparison of demographic characteristics of women who received SD in different periods was performed according to age at the beginning of the treatment, marital status (single women and same sex female couples, heterosexual couples), and ethnic origin.

Results: The average age of women who received SD was 37.02 ± 5.36 years. The average patient age rose from 35.08 years in 1992–1997 to 37.43 years in 2017–2021 (P-value < 0.01). The use of SD was more common among single women and same sex female couples compared to heterosexual couples in later years. Regarding single and same sex female couple, the percentage of SD recipients increased radically from 33% to 88.1% (P-value < 0.01).

Conclusions: Modern sperm banks treat older patients in non-heterosexual relationships. These trends encompass not only medical implications (e.g., in vitro fertilization vs. intrauterine insemination) but also delve into the personal and sociological impact experienced by both patients and offspring.

Background: In Israel, breast cancer prevalence is lower among Arab than Jewish women, but incidence is increasing among Arab women at a younger age.

Objectives: To explore differences between Arab and Jewish women with breast cancer with respect to age at diagnosis, associated risk factors, and use of hormonal medications.

Methods: We conducted a retrospective database study comparing Arab and Jewish women with breast cancer focusing on age at diagnosis, smoking history, obesity, and previous hormonal medication usage, including oral combined contraceptive pills (OCCP), progestogens, hormonal medications for treatment of infertility, and hormone replacement therapy (HRT).

Results: The study included 2494 women who were diagnosed with breast cancer during 2004–2015. Age at diagnosis was lower among Arab women (50.7 ± 13.1 years vs. 55.4 ± 12.6 years, P < 0.0001). The rate of smoking was higher among Jewish women (16.0% vs. 4.3%, P < 0.0001). The rate of obesity was higher in Arab women older than 50 years at diagnosis (59.0% vs. 42.4%, P < 0.0001). Arab women demonstrated a lower overall chance of previous use of all types of hormonal medications (odds ratio [OR] 0.6, 95% confidence interval [95%CI] 0.6–0.8) compared to Jewish women. Arab women were more likely to have used progestogens (OR 1.7, 95%CI 1.4–2.2) and medications for treatment of infertility (OR 2.3, 95%CI 1.5–3.4) and less likely OCCP (OR 0.4, 95%CI 0.3–0.6) and HRT (OR 0.4, 95%CI 0.3–0.5).

Conclusions: Previous use of hormonal medications may contribute to incidence of breast cancer in Arab women.

Background: Omega-3 fatty acids promote fertility in males and females and constitute an important factor in the normal development of the fetus.

Objectives: We investigated the effect of omega-3 supplements during ovulation induction treatment in women with polycystic ovary syndrome (PCOS)-related infertility.

Methods: A randomized, double-blind study was conducted for 60 treatment cycles in 34 women with PCOS-related oligo/anovulation referred to the fertility clinic at the Bikur Cholim/Shaare Zedek Medical Center in Jerusalem, who underwent ovulation induction with clomiphene citrate (50 mg). Seventeen women (mean age 33.9 ± 0.9 years) received omega-3 supplements (3 × 600 mg/day) and 17 received placebo capsules (mean age 32.7 ± 0.9 years) for a maximum of two cycles. We recorded their characteristics and data from their serial hormonal blood tests and ultrasound examinations. We also conducted both univariate and multivariate analyses. The primary endpoint was conception.

Results: There were clinical pregnancies in 8/30 (26.7%) treatment cycles for women receiving omega-3 supplements versus 4/30 (13.3%) cycles with placebo. Among overweight/obese women (body mass index [BMI] 25–35), there were clinical pregnancies in 8/27 cycles (29.6%) versus 1/19 (5.3%) with placebo (P < 0.04). For overweight/obese PCOS women, omega-3, lower BMI rates, and higher values of the endometrium’s thickness increased the odds of becoming pregnant. No harmful side effects from the omega-3 treatment were reported.

Conclusions: Omega-3 supplements demonstrated beneficial effects for fertility in women diagnosed with PCOS. Among the overweight/obese participants, the increased clinical pregnancy rate was significant.

Background: Diagnosing occult stress urinary incontinence (OSUI) prior to surgical intervention for pelvic organ prolapse (POP) repair may allow for adding an anti-incontinence procedure and thus prevent postoperative SUI.

Objectives: To compare preoperative detection rates for OSUI by either a multichannel urodynamic investigation or by a plain pelvic examination.

Methods: We retrospectively evaluated the medical charts of all women who underwent urodynamic investigation prior to surgical repair of advanced POP at our institution between 1 January 2006 and 31 December 2012.

Results: In total, 720 women underwent surgical POP repair during the study period, of whom 54 (7.5%) were diagnosed with OSUI preoperatively. Of these patients, 54 (100%) were detected by multichannel urodynamic investigation while only 27 (50%) were detected by a plain pelvic examination (P = 0.001). Bladder fullness during the pelvic examination was associated with higher detection rates for OSUI (P = 0.001). Women with OSUI who underwent concomitant tension-free vaginal tape and POP repair procedures did not develop de novo SUI or obstructive voiding symptoms (OVS) postoperatively.

Conclusions: Preoperative multichannel urodynamic investigation has significantly higher detection rates for OSUI than a plain pelvic examination. Utilizing this modality resulted in no cases of de novo SUI or OVS postoperatively.

Background: Pregestational diabetes mellitus (PGDM) carries a significantly elevated risk of adverse maternal and fetal outcomes. There is evidence that certain interventions reduce the risk for adverse outcomes. Studies have shown that a multi-disciplinary approach improves pregnancy outcomes in women with PGDM.

Objectives: To determine pregnancy outcomes in women with PGDM using a multi-disciplinary approach.

Methods: We retrospectively reviewed consecutive women with pregestational type 1 and type 2 diabetes who were monitored at a high-risk pregnancy clinic at the Sheba Medical Center. Clinical data were obtained from the medical records. All data related to maternal glucose control and insulin pump function were prospectively recorded on Medtronic CareLink® pro software (Medtronic MiniMed, Northridge, CA).

Results: This study comprised 121 neonates from 116 pregnancies of 94 women. In 83% of the pregnancies continuous glucose monitoring (CGM) sensors were applied during a part or all of the pregnancy. Pregnancy outcomes among women who were followed by a multi-disciplinary team before and during pregnancy, and during labor and puerperium resulted in better glucose control (hemoglobin A1c 6.4% vs. 7.8%), lower risk for pregnancy induced hypertension/preeclampsia (7.7% vs. 15.6%), lower birth weight (3212 g vs. 3684 g), and lower rate of large size for gestational age and macrosomia (23.1% vs. 54.2% and 3.3% vs. 28.4%, respectively), compared to data from European cohorts.

Conclusions: The multi-disciplinary approach for treating women with PGDM practiced in the high-risk pregnancy clinic at the Sheba Medical Center resulted in lower rates of macrosomia, LGA, and pregnancy induced hypertension compared to rates reported in the literature.

Background: Isolated fallopian tube torsion (IFTT) is a rare gynecological entity and its diagnosis is challenging.

Objectives: To compare clinical characteristics, sonographic findings, surgical management, and outcomes of women with surgically verified IFTT compared to those diagnosed with adnexal torsion.

Methods: A retrospective case-control study in a university hospital was conducted. Thirty-four women with surgically verified IFTT between March 1991 and June 2017 were compared to 333 women diagnosed with adnexal torsion within the same time period.

Results: Both groups presented primarily with abdominal pain, which lasted longer prior to admission among the IFTT group (46.8 ± 39.0 vs. 30.0 ± 39.4 hours, P < 0.001). Higher rates of abdominal tenderness with or without peritoneal signs were found in the adnexal torsion group (90.3% vs. 70.6%, P < 0.001). Sonographic findings were similar; however, an increased rate of hydrosalpinx was found among the IFTT group (5.9% vs. 0.0%, P = 0.008). Suspected adnexal torsion was the main surgical indication in only 61.8% of IFTT cases compared with 79.0% in the adnexal torsion group (P = 0.02). Salpingectomy with or without cystectomy was more commonly performed in the IFTT group (35.3% vs. 1.5%, P < 0.001). The leading pathological findings among the IFTT group were hydrosalpinx and paraovarian cysts.

Conclusions: The clinical signs and symptoms of IFTT and adnexal torsion are similar. Although sonographic imaging demonstrating a paraovarian cyst or hydrosalpinx may be helpful in diagnosing IFTT, it is rarely done preoperatively.

Background: Young women concerned about a breast cancer diagnosis will visit breast care centers and request breast cancer screening, including imaging studies, on their initial visit.

Objectives: To explore the role of breast examination and breast ultrasound in self-referred asymptomatic women under the age of 40 years.

Methods: We identified 3524 women under the age of 40 at our medical clinic from 1 January 2010 until 1 June 2014. Of this group, 164 women with above average breast cancer risk were excluded and 233 were excluded because of breast complaints. Of 3127 women, 220 underwent breast ultrasound following the initial visit to the clinic and formed the study group.

Results: Of 220 women evaluated with ultrasound, 68 had prior positive clinical findings. Of this group 8 women had no sonographic findings, and in the remaining 60, a total of 30 simple cysts, 15 fibroadenomas, and 15 suspicious solid masses were identified. One infiltrating ductal carcinoma and one ductal carcinoma in situ were found in a biopsy. The remaining 152 of the 220 total women who underwent breast ultrasound without showing prior physical findings did not require follow-up.

Conclusions: In the absence of clinical findings during physical breast examination, the addition of breast ultrasonography does not provide additional information to supplement the physical examination in self-referred women under age 40 who do not have any major risk factors for developing breast cancer.

Background: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway.

Objectives: To examine a possible association between NAFLD and rUTIs among premenopausal women.

Methods: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination.

Results: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3–2.0, P = 0.04) were associated with rUTIs in premenopausal women.

Conclusions: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.

Background: Although women comprise only a minority of patients hospitalized due to violence-related injury, the circumstances of attacks against women may make their injuries more severe.

Methods: We conducted a retrospective study using data of 9173 patients with stabbing-related injuries from 19 trauma centers participating in the Israeli National Trauma Registry between 1 January 1997 and 31 December 2014. Male and female patients were compared in terms of demographic and circumstantial factors, clinical characteristics, and outcomes.

Results: Women were found to have greater injury severity according to the Injury Severity Scale (ISS) – 18% vs. 11% of severe (ISS 16+) injuries – requiring more hospital resources. Injuries that contributed most to injury severity in the female population were head and severe abdominal trauma. Women also sustained injuries to more body sites than men; however, regression analysis showed that the contribution of this factor to the overall difference in injury severity was less important than the injured sites. Regression analysis among severely injured patients pointed at injury to lower extremities as an independent factor related to female mortality. Different from men, among women the stabbing injuries to the upper extremities were not a protective factor in terms of mortality.

Conclusions: There are significant differences in the injury profiles of male and female stabbing victims, which can be explained by the different circumstances of the injury event.

Background: Rheumatic mitral stenosis (MS) is a relatively rare diagnosis in the developed countries and its treatment during pregnancy is challenging due to hemodynamic changes. With the demographic changes due to recent waves of immigration an increase in the prevalence of rheumatic heart disease is expected.

Objective: To evaluate maternal and neonatal complications in patients with mitral stenosis.

Methods: During the years 2006–2017, 22 women who underwent 31 pregnancies were followed at the Sheba Medical Center in Israel. We collected on regarding hemodynamic changes and their clinical course. MS was classified as mild, moderate, or severe according to mitral valve area by echocardiography. Maternal and fetal adverse events were evaluated according to severity of MS and compared by Poisson regression modeling.

Results: MS was severe in 7 pregnancies (22.6%), moderate in 9 (29%), and mild in 15 (48.4%). Twenty patients were managed conservatively and 2 underwent a successful percutaneous mitral balloon valvuloplasty (PBMVP) during pregnancy. All pregnancies ended with a liveborn neonate and with no maternal mortality. Peak and mean mitral pressure gradients increased during pregnancy from 13.3 ± 5.3 to 18.6 ± 5.1 mmHg and from 5.9 ± 2.3 to 9.6 ± 3.4 mmHg respectively (P < 0.05). Eight pregnancies (25.8%) were complicated by pulmonary congestion, 2/15 (13.3%) with mild MS, 2/9 (22.2%) with moderate, and 4/7 (57.1%) with severe MS. The adverse event rate was higher among patients with severe MS compared with moderate and mild MS [hazard ratio (HR) 3.15, 95% confidence interval (95%CA) 1.04–9.52 and HR 4.06, 95%CI 1.4–11.19 respectively, P < 0.05]. Nine of 31 deliveries were vaginal; 6 of 22 cesarean sections (27.3%) were performed for cardiac indications.

Conclusions: The number of total adverse events were higher among patients with severe MS. Patients with moderate and mild MS should be treated attentively, but good obstetric and maternal outcome can be expected.

Background: Catheter ablation (CA) is a well-established therapeutic option for patients with recurrent symptomatic atrial fibrillation (AF). Data on gender-related differences are limited with regard to baseline characteristics and long-term success rates of catheter ablation for AF.

Methods: We analyzed a cohort of 251 consecutive patients who underwent a first catheter ablation for AF in our institute during the period 2008 through 2015. All patients were followed by regular annual clinic visits, electrocardiograms, periodic 24–48 hour Holter monitoring, and loop recorders. The primary endpoint was first recurrence of AF during 1 year of follow-up.

Results: The cohort comprised 26% women (n=65), who were older (62.1 ± 9.6 vs. 54.4 ± 11.3 years, P < 0.01) and had a higher proportion of diabetes mellitus (23.1 vs. 5.4%, P < 0.001) than male patients. No other significant differences were evident. At 1 year follow-up, the cumulative survival free of AF was significantly higher in women compared with men (83% vs. 66%, respectively, log rank P value = 0.021). Subgroup analysis showed an interaction between female and small indexed left atrial diameter (LADi < 23 mm/m2).

Conclusions: Our findings suggest that women experience a significantly lower rate of AF recurrence post-CA compared with men. This gender-related advantage appears to be restricted to women without significant left atrial enlargement. It further implies that left atrial enlargement has a stronger negative impact on post-CA AF recurrence in females than in males. Due to the relatively small sample number of females further research is warranted to validate our conclusions.

Background: The recommendation of the U.S. Centers for Disease Control and Prevention regarding universal screening for Group B Streptococcus (GBS) at 35–37 weeks gestational age in pregnancy is not accepted in Israel. The National Council for Obstetrics, Neonatology and Genetics recommends intrapartum prophylaxis, mainly based on risk factors, to prevent early neonatal GBS infection. This policy is based on past studies demonstrating low colonization rates of the bacteria in Israeli pregnant women and very low neonatal sepsis rates.

Objectives: To determine the applicability of the high-risk group prophylaxis policy for Arab Israeli pregnant women.

Methods: Vaginorectal swabs from Arab Israeli pregnant women who attended the labor ward between October 2015 and February 2016, were obtained before any pelvic examination for GBS identification using Quidel’s AmpliVue® GBS assay. Women who tested positive received intrapartum antibiotic prophylaxis to prevent neonatal infection. Obstetric data were collected from each woman from a standardized questionnaire. Data regarding the delivery and neonates were collected as well.

Results: The study comprised 188 Arab pregnant women who met the inclusion criteria and signed a consent form to participate in the study. Of these, 59 had positive tests, and a carriage rate of 31%. No neonatal colonization of GBS was found.

Conclusions: The carrier rate in Arab pregnant women in northern Israel is higher than the national average, at least partially due to the more sensitive method of GBS detection used in the present study.
