On Saturday, 7 October 2023, the Jewish holiday of Simchat Torah, our entire country woke to a reality of the worst terror attacks it has ever known, despite its long history of wars and terror. These horrific attacks included killing and burning babies, children, women, men, and the elderly; raping women; beheading babies; destroying settlements; and kidnapping more than 240 civilians and soldiers. The severe traumatic events created different circles of those exposed to trauma. In each group, the intensity of the trauma was different and had different characteristics.

Background: Unfractionated heparin is the preferred anticoagulant used during open heart surgeries, including left ventricular assist device (LVAD) implantation. In cases in which patients are heparin-induced thrombocytopenia positive (HIT+), the accepted practice has been to substitute heparin with bivalirudin. This practice may be associated with significant bleeding and adverse outcomes.

Objectives: To review our experience with HIT+ patients who were heparin-induced thrombocytopenia with thrombosis negative (HITT-) and who underwent HeartMate 3 LVAD implantation using heparin intraoperatively rather than bivalirudin.

Methods: From 2016 to 2022, 144 adult patients were implanted with HeartMate 3 LVAD at our center. Among them, 7 were detected as HIT+ but HITT- and therefore were prescribed intraoperatively with heparin and treated pre- and postoperatively with bivalirudin. We reviewed the preoperative, intraoperative, and postoperative characteristics as well as short-term mortality and the complication rates of these HIT+ patients.

Results: The median age of our cohort was 56 years (51–60), 71% were male (n=5), all were INTERMACS Level 1, and most were bridged to transplant (n=6, 86%). The 30-day mortality rate post-implantation was 0%. The average 24-hour chest drain postoperative output was 1502.86 ± 931.34 ml. There were no intraoperative pump thromboses, perioperative thromboses, cerebrovascular accidents, or gastrointestinal bleeding within the first 24 hours postoperative. One patient required a revision due to bleeding.

Conclusions: Intraoperative unfractionated heparin may be administered to patients who are HIT+ and HITT- while undergoing LVAD implantation. However, further investigation is required.

Background: The French AmbUlatory Cesarean Section (FAUCS) technique was introduced to the Galilee Medical Center in September 2021. FAUCS was performed electively for interested women who meet the criteria.

Objectives: To evaluate the learning curve of senior surgeons performing FAUCS, the procedure short-term outcomes, and complications.

Methods: This retrospective study included 50 consecutive women who underwent FAUCS from September 2021 until March 2022 at our facility. Preoperative, intraoperative, postoperative, and demographic data were retrieved from patient electronic charts.

Results: The mean duration of surgery was 53.26 ± 11.62 minutes. This time decreased as the surgical team's experience increased: from a mean 58.26 ± 12.25 minutes for the first 15 procedures to a mean 51.17 ± 9.73 minutes for subsequent procedures. The mean visual analogue scale score for 24 hours was 1.08 ± 0.84 (on a 10-point scale). The rate of neonatal cord pH < 7.2 was 6%, and there were 11.3% cases of vacuum assisted fetal extraction. In total, 44% of the women were able to mobilize and urinate spontaneously by 4–6 hours. Complications included bladder injury (n=1), endometritis (n=1), and incisional hematoma (n=1). Overall, the maternal satisfaction rate was high; 94% of the women would recommend FAUCS to others.

Conclusions: FAUCS is a feasible procedure with a high satisfaction rate. Following the first 15 procedures performed by one surgical team, the operative time decreased considerably. Further randomized controlled studies are needed to compare this procedure to regular cesarean section and evaluate neonatal outcomes.

Background: Fetal facial clefts are among the most common congenital anomalies detected prenatally. This finding may lead to termination of pregnancy in some cases.

Objectives: To compare a cohort of fetuses with facial clefts in which the pregnancy was terminated to the cohort of cases that were born with facial clefts. To investigate risk factors for facial clefts.

Methods: We conducted a retrospective chart review of all women with prenatal and postnatal diagnosis of facial cleft that were managed in our institute. A telephone questionnaire was conducted regarding a positive family history and/or genetic predisposition for facial clefts abnormalities.

Results: The final cohort consisted of two group. One group included 54 cases of termination of pregnancy (TOP) that were performed due to cleft lip (CL) or cleft palate (CLP); 27 women answered the telephone questionnaire. The second group comprised 99 women who delivered children with facial cleft during the same period; 60 answered the questionnaire. Only seven cases were diagnosed prenatal. Among the two groups, no correlation to family history was discovered. Of note, there was one case of three consecutive fetuses with CL in one woman, without any significant genetic findings.

Conclusions: To the best of our knowledge, this is the first study to describe an anatomical malformation posing an ethical dilemma before TOP. Primary prevention with folic acid and early sonographic detection of CL/CLP with multidisciplinary consultation should be considered.

Rheumatoid arthritis (RA) is an autoimmune chronic inflammatory disease characterized by synovitis leading to polyarthritis. It affects 1% of the population [1]. Genetic and environmental factors are linked to the development of RA and include the presence of HLA-DR4 and shared epitope, and smoking is the primary representative of the negative environmental factor [1].

However, RA mainly affects middle age. Late-onset RA that initiates after 60 years is sometimes named elderly onset rheumatoid arthritis (EORA) [2]. This disease's prevalence varied from 2.03% to 2.34% in a large study in the United States. EORA affects more women than men [1]. However, to the best of our knowledge, no patient description of RA initiated at 97 years of age has been described.

Background: Congestive heart failure (CHF) with reduced ejection fraction (HFrEF) or with preserved ejection fraction (HFpEF) is a common diagnosis in patients hospitalized in the department of internal medicine. Recently, the therapeutic regimens were updated, as the sodium-glucose cotransporter-2 (SGLT2) inhibitors became an integral part of the therapeutic regimen for either HFrEF or HFpEF.

Objectives: To define the demographic and clinical characteristics of CHF patients hospitalized in the department of medicine.

Methods: We conducted a retrospective cohort study that included all patients hospitalized in the departments of medicine at the Rabin Medical Center, Israel, between 2016 and 2019. Demographic and clinical background, in-hospital procedures, discharge regimens, and outcome parameters were evaluated according to HFrEF/HFpEF.

Results: The cohort included 4458 patients. The majority (97%) presented with a preexisting diagnosis, whereas HF was an active condition in only half of them. The rates of HFrEF/HFpEF were equal. In most cases, the trigger of the exacerbation could not be determined; however, infection was the most common cause. There were basic differences in the demography, clinical aspects, and therapeutic regimens at discharge between HFrEF and HFpEF. Both conditions were associated with high in hospital mortality (8%) and re-admissions rates (30 days [20%], 90 days [35%]) without any difference between them.

Conclusions: HFrEF/HFpEF patients differed by demographics and co-morbidities. They were equally represented among patients admitted to medical wards and had similar prognosis. For both diagnoses, hospitalization should be considered for updating therapeutic regimens, especially with SGLT2 inhibitors.

Migraine is very common headache disorder, usually starting at a young age with a higher prevalence in females. In this narrative review, we summarize the prevalence, burden, and socio-demographic characteristics of migraineurs worldwide and specifically in Israel. We searched standard electronic bibliographic databases, including MEDLINE (via PubMed), Embase, Google Scholar, and Up to Date using combinations of search terms and reviewed the articles we found. The factors reviewed included prevalence and incidence, burden, sex differences, age distribution, cognitive function, socioeconomic status, religion, country of origin, and urban vs. rural dwelling.

Recognizing myocarditis is a diagnostic and therapeutic challenge due to the heterogeneity of its clinical presentation and the wide range of etiologies. There is a lack of uniformity among position papers and guidelines from various professional societies regarding the definition and diagnostic workout, including recommendations for performing endomyocardial biopsy (EMB) and medical management, especially the use of immunosuppressive regimens [1-3]. Moreover, there is significant variability among medical centers in Israel in the diagnostic and therapeutic approaches to acute myocarditis. The purpose of this position paper is to present ways to standardize the management of acute myocarditis in Israel [4] by providing up-to-date definitions of the clinical categories of myocarditis, diagnostic criteria, and therapeutic approaches that correspond to the realities of our healthcare system.

In the position statement on the definition and diagnosis of acute myocarditis on page XXX of this issue of the Israel Medical Association Journal (IMAJ), we discussed contemporary criteria for definition of acute myocarditis and inflammatory cardiomyopathy [1-6]. We also addressed current diagnostic methods including indications for endomyocardial biopsy (EMB) [7-21]. In this position statement, we discuss the management approaches during hospitalization and following hospital discharge, including specific forms of myocarditis and recommendations for returning to physical activity after myocarditis [21-36].

Background: Peripartum cardiomyopathy (PPCM) is a rare but potentially devastating complication of pregnancy. Although the pathophysiology of PPCM is not fully understood, there are known risk factors for developing PPCM, which are maternal and gestation related. In the first wave of the coronavirus disease 2019 (COVID-19) pandemic, we witnessed an elevated incidence of PPCM among COVID-19 survivors.

Objectives: To present a single-center case series of three patients diagnosed with peripartum cardiomyopathy after recovered from COVID-19 during the index pregnancy.

Methods: In this single center case study, all patients diagnosed with PPCM at our institute during the examined time frame were included. Electronic medical records were studied.

Results: Three patients previously diagnosed with asymptomatic or mildly symptomatic COVID-19 disease during pregnancy presented with PPCM before or shortly after delivery. Patients underwent testing to rule out residual COVID-19 myocarditis, were treated pharmacologically and with wearable defibrillators as needed, and were examined in follow-up 1–9 months after delivery.

Conclusions: Residual endothelial damage due to COVID-19 disease, even if originally mild in presentation, could predispose pregnant patients to PPCM and should be considered as a risk factor when assessing patients with new onset symptoms of heart failure. Further research is needed to confirm this hypothesis and fully determine the underlying pathophysiology. These preliminary findings warrant a high index of suspicion for PPCM in COVID-19 recoverers.

Background: Brucellosis is an endemic infection affecting the Mediterranean Basin, Arabian Peninsula, India, Mexico, and South America. Data on brucellosis infections in children are limited.

Objectives: To review and characterize the clinical presentation of pediatric patients diagnosed with brucellosis in a tertiary medical center.

Methods: Retrospective data analysis was conducted on all pediatric patients from January 2010 to December 2020 admitted to the pediatric department with a diagnosis of brucellosis based on a positive serology test or growth of Brucella bacteria in blood culture.

Results: The study comprised 53 children aged 0–18 years. The mean age at presentation was 11.01 ± 4.91 years; 39 male (73.6%). Pre-infection exposure to unpasteurized milk or unvaccinated livestock was reported in 37 (69.8%). Fever was present in 64.6%, followed by arthralgia (49%), loss of appetite (42.3%), and weight loss (24.6%). Gastrointestinal symptoms were reported in 52.8% and included abdominal pain (34.6%), nausea (28.3%), vomiting (24.5%), and diarrhea (2.6%). Eight patients experienced pancytopenia (15.1%). The median length of intravenous antibiotic treatment was 7 days (range 3–14 days) and for oral antibiotic treatment 6 weeks (range 2–24 weeks). Most patients were initially treated with intravenous gentamycin (90.5%) and long-term oral antibiotics, most commonly doxycycline. Two (3.7%) required admission to the pediatric intensive care unit. No mortality was documented, and all cases of relapses were successfully treated.

Conclusions: Pediatric brucellosis is an acute febrile disease often associated with rheumatologic complaints. Patients 8–18 years of age also presented with headache, weight loss, and night sweats.

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.

Thyroid storm-related heart failure is a rare, life threatening complication of hyperthyroidism. In refractory cases, urgent thyroidectomy is required for definitive control of thyrotoxicosis. venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a supportive measure for cardiorespiratory failure requiring continuous anticoagulation to prevent clotting. We presented two cases of thyrotoxic cardiac failure that necessitated VA-ECMO. One of the patients was successfully treated with thyroidectomy while on VA-ECMO. To the best of our knowledge, only two such cases have previously been reported.

Background: Children with forearm fractures who present to the emergency department (ED) often need a closed reduction. In our institution, until 2017, pediatric trauma patients presented to the general trauma ED (GTED) where no sedation services for pediatric patients were available. From 2017, patients presented to the pediatric emergency department (PED) where closed reductions were performed under sedation when appropriate.

Objectives: To compare GTED and PED with regard to length of stay (LOS) and hospitalization rates of pediatric patients with forearm fractures who needed a closed reduction.

Methods: Our retrospective observational study was conducted at a regional hospital. The study population consisted of all patients younger than 18 years of age who presented to the ED with a forearm fracture that needed a closed reduction. The primary outcome measure was the hospitalization rate. The secondary outcome measure was LOS in the ED.

Results: The study comprised 165 patients with forearm fractures who needed a closed reduction; 79 presented to the GTED, and 96 presented to the PED. Hospitalization rates were lower for patients undergoing closed reduction under sedation in the PED compared to the GTED (6.3% and 21.5%, respectively; P = 0.003). Median ED LOS was longer among patients undergoing sedation in the PED compared to the GTED (237 vs. 168 minutes respectively, P < 0.0001).

Conclusions: Sedation for forearm fracture reduction in a hospital’s PED was associated with a decrease of more than three times in hospitalization rate. Despite the need for more resources, PED LOS was only mildly increased.

Background: Intrathoracic cancer can cause hyponatremia, but it is uncertain whether mild hyponatremia in the outpatient setting should be regarded as an early sign of intrathoracic cancer.

Objectives: To evaluate the risk of undiagnosed intrathoracic cancer in patients with new persistent mild hyponatremia.

Methods: We conducted a retrospective cohort study using the electronic health record database of a large healthcare organization. The hyponatremia group included patients with sodium concentration of 130–134 mmol/L twice, after a previous normal value and without previous history of cancer or diseases related to hyponatremia. A control group with normal sodium concentration was matched by sex, age, and year of testing. We measured specific intrathoracic cancer incidence during 3 years of follow-up after sodium concentration test date. A logistic regression was used to adjust for further clinical information including smoking history, symptoms, and medications.

Results: The study comprised 1539 participants with mild hyponatremia and 7624 matched controls. New intrathoracic cancer diagnosis was more common in the hyponatremia group during a 3-year follow-up; 1.49% in the hyponatremia group and 0.39% in the control group, crude odds ratio (OR) 3.84, 95% confidence interval (95%CI) 2.22–6.63. After adjustment, hyponatremia remained a significant risk factor for the diagnosis of intrathoracic cancer; adjusted OR 3.61, 95%CI 2.08–6.28.

Conclusions: New mild persistent hyponatremia might be a significant predictive marker to a yet undiagnosed intrathoracic cancer.
