Background: Uterine tachysystole during labor can lead to a decrease in fetal oxygen saturation and intracerebral oxygen saturation. Acute tocolysis using atosiban can inhibit uterine smooth muscle activity, potentially improving fetal status and facilitating vaginal delivery or allowing time to prepare for operative delivery.

Objectives: To compare maternal and neonatal outcomes in cesarean and vaginal deliveries following atosiban administration during fetal prolonged deceleration and tachysystole at gestational age 37 0/7 to 43 0/7 weeks.

Methods: We conducted a single-center, descriptive retrospective cohort study at a large tertiary referral center.

Results: Of the 275 patients treated with atosiban, 186 (68%) delivered vaginally (either spontaneous delivery or instrumental delivery) and 89 (32%) underwent a cesarean delivery. In a univariate analysis, cesarean delivery was associated with higher body mass index (27.9 ± 4.3 vs. 30.2 ± 4.8, P = 0.003). Second stage atosiban administration was associated with vaginal delivery (89.3% vs. 10.7%, P = 0.01). Cesarean delivery was associated with lower Apgar at 1 and 5 minutes and a higher rate of neonatal intensive care unit admissions. The incidence of PPH among women treated with atosiban in our study (2.3–4.3%) was higher than the incidence reported in the literature (1–3%)  

Conclusions: Atosiban may be an effective acute intervention for non-reassuring fetal heart rate during tachysystole, increasing the rate of vaginal delivery and potentially reducing the need for cesarean delivery. However, the potential risk of postpartum hemorrhage should be taken into consideration.

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: Breast implant-associated anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin's lymphoma that is found around breast implants. ALCL was discovered only two decades ago. In Israel we currently have four diagnosed cases (as of 2018). Until recently, the estimated incidence was 1:300,000 women with breast implants, while recent reports range from 1:3817 to 1:30,000. 

Objectives: To determine the occurrence of breast implant-ALCL in Israel.

Methods: We conducted a retrospective analysis of the four patients diagnosed with ALCL in Israel. Cytology was confirmed and the clinical data was collected. Based on the estimated number of women with breast implants in Israel, a calculation of the true incidence was completed.

Results: The incidence in Israel is significantly higher than the older incidence reports indicate. We estimated that the lifetime prevalence of the disease is 4:60,000 women with a textured breast implant, or 1:15,000 women with a textured breast implant in Israel.

Conclusions: ALCL is not common. We support the claim that the prevalence is significantly higher than what was initially described. This finding has clinical and medicolegal implications that should be addressed accordingly.

Background: Pneumonia is a major cause of morbidity and mortality in burn patients with inhalation injuries. An increased risk of pneumonia has been demonstrated in trauma and burn patients urgently intubated in the field vs. emergency departments (EDs).

Objectives: To compare intubation setting (field vs. ED) and subsequent development of pneumonia in burn patients and to evaluate the indication for urgent intubation outside the hospital setting.

Methods: A retrospective medical records review was conducted on all intubated patients presenting with thermal (study group, 118 patients) or trauma (control group A, 74 patients) injuries and admitted to the intensive care unit of a level I trauma and burn center at a single institution during a 15 year period. Control group B (50 patients) included non-intubated facial burn patients hospitalized in the plastic surgery department.

Results: Field intubation was less frequent (37% field vs. 63% ED), although it was more frequent in larger burns (total body surface area > 50%; 43% field vs. 27% ED). More field intubated patients developed pneumonia during hospitalization (65% field vs. 36% ED [burns]; 81% field vs. 45% ED [multi-trauma]; 2% non-intubated, P < 0.05), with a significantly higher all-cause mortality (49% field vs. 24% ED, P < 0.05) and dramatically lower rates of extubation within 3 days (7% field vs. 27% ED, P < 0.05).

Conclusions: Field intubation is associated with a higher risk of subsequent development of pneumonia in burn and multi-trauma patients and should be applied with caution, only when airway patency is at immediate risk.

Background: Abnormal gestational weight gain (GWG) has been associated with adverse outcomes for mothers and their offspring.

Objectives: To compare the achievement of recommended GWG and lifestyle factors in women with high-risk versus normal-risk pregnancies.

Methods: Pregnant women hospitalized in a gynecological and obstetrics department and pregnant women who arrived at a community clinic for a routine checkup were interviewed and completed questionnaires relating to weight gain and lifestyle factors (e.g., smoking, diet, exercise). Recommended GWG was defined by the American Congress of Obstetricians and Gynecologists (ACOG).

Results: GWG higher than ACOG recommendations was reported by 52/92 women (57%) with normal pregnancies and by 43/86 (50%) with high-risk pregnancies. On univariate analysis, characteristics associated with greater GWG were: current or past smoking, age > 40 years, pre-gestational body mass index (BMI) > 25 kg/m², low fruit intake, and high snack intake. High-risk pregnancies were associated with pre-gestational BMI > 25 kg/m² (48% vs. 27%, P = 0.012), consumption of vitamins (84% vs. 63%, P = 0.001), avoidance of certain foods (54% vs. 21%, P = 0.015), receiving professional nutritionist consultation (65% vs. 11%, P = 0.001), and less physical activity (9% vs. 24%, P = 0.01).

Conclusions: A minority of pregnant women met the recommended GWG. No difference was noted between normal and high-risk pregnancies. High-risk population tended to have a less healthy lifestyle. Counseling to follow a healthy, balanced diet should be recommended, regardless of pregnancy risk, with particular attention to women at high risk of extra weight gain.

Background: Both high and insufficient weight gain during pregnancy have been associated with adverse outcomes for mothers and their offspring.

Objectives: To describe self-reported weight gain during pregnancy, assess the concurrence of this weight gain with issued recommendations, and investigate associations between lifestyle factors and weight gain.

Methods: In this cross-sectional study, 109 pregnant women hospitalized in one gynecological and obstetrics department completed questionnaires related to weight gain and lifestyle factors such as smoking, diet and exercise. Recommended weight gain was defined by the American Congress of Obstetricians and Gynecologists and was compatible with the Ministry of Health guidelines in Israel.

Results: Fifty-three (49%) participants reported weight gain above the recommendation, 31 (28%) met the recommendations and 25 (23%) reported weight gain below the recommendations. Characteristics associated with high weight gain included past smoking and/or age above 36 years and/or body mass index (BMI) above 25 kg/m². Only 34 women (31%) reported seeking professional nutritional counseling during pregnancy. An increased tendency to consult a nutritionist was reported among diabetic women.

Conclusion: Only a minority of women gained the recommended weight during pregnancy. High BMI and/or a history of smoking and/or older age were associated with weight gain above recommendations. Particular effort should be directed toward counseling women at high risk of weight gain during pregnancy.

Background: The marijuana plant cannabis is known to have therapeutic effects, including improvement of inflammatory processes. However, no report of patients using cannabis for Crohn’s disease (CD) was ever published.

Objectives: To describe the effects of cannabis use in patients suffering from CD.

Methods: In this retrospective observational study we examined disease activity, use of medication, need for surgery, and hospitalization before and after cannabis use in 30 patients (26 males) with CD. Disease activity was assessed by the Harvey Bradshaw index for Crohn’s disease.

Results: Of the 30 patients 21 improved significantly after treatment with cannabis. The average Harvey Bradshaw index improved from 14 ± 6.7 to 7 ± 4.7 (P < 0.001). The need for other medication was significantly reduced. Fifteen of the patients had 19 surgeries during an average period of 9 years before cannabis use, but only 2 required surgery during an average period of 3 years of cannabis use.

Conclusions: This is the first report of cannabis use in Crohn’s disease in humans. The results indicate that cannabis may have a positive effect on disease activity, as reflected by reduction in disease activity index, and in the need for other drugs and surgery. Prospective placebo-controlled studies are warranted to fully evaluate the efficacy and side effects of cannabis in CD.
 

Background: Crohn's disease and ulcerative colitis are inflammatory bowel diseases with an unknown etiology. Interleukin-18 is a pro-inflammatory cytokine that is up-regulated in Crohn’s disease. IL-18[1] binding protein neutralizes IL-18. The relationship of IL-18 and IL-18BP[2] and disease activity in these diseases is not fully understood.

Objectives: To investigate the correlation of IL-18 and IL-18BP with disease activity and other disease parameters in inflammatory bowel disease.

Methods: IL-18 and IL-18BP isoform α were measured in 129 patients and 10 healthy individuals. Patients' mean age was 40.5 (range 15–70 years) and 43 were women; 58 Crohn's and 28 colitis patients were in remission and 52 and 14, respectively, were in exacerbation. Twenty-three (19 and 4 respectively) were studied in both remission and exacerbation.

Results: The mean level of free IL-18 was significantly different between healthy individuals and Crohn's patients, and between Crohn's patients during exacerbation and remission (167 ± 32 vs. 471 ± 88 and 325 ± 24 pg/ml, respectively, P < 0.05). Mean level of IL-18BP was significantly different between healthy individuals and Crohn patients, and between Crohn patients during exacerbation and remission (2.1 ± 1.1, 7.5 ± 4 and 5.23 ± 2.8 ng/ml, respectively, P < 0.01). In the colitis patients, mean free IL-18 level and IL-18BP were significantly different between healthy individuals and patients, but not between disease remission and exacerbation (167 ± 32, 492 ± 247 and 451± 69 pg/ml for IL-18, and 2.1 ± 1.1, 7.69 ± 4 and 6.8 ± 7 ng/ml for IL-18BP, respectively, P = 0.05).

Conclusions: IL-18 and IL-18BP levels are higher in patients with inflammatory bowel disease compared to healthy individuals. In Crohn's disease, but not in ulcerative colitis, IL-18 (but not free IL-18) and IL-18BP levels are significantly higher during exacerbation compared to remission. This observation highlights the importance of IL-18 in the pathogenesis of inflammatory bowel diseases, especially in Crohn's disease.
