Background: The management of symptomatic abdominal aortic aneurysms (AAA) remains a surgical challenge.

Objectives: To compare the outcomes of endovascular aneurysm repair (EVAR) versus open surgical repair (OSR) in patients with symptomatic AAA.

Methods: Patients treated for symptomatic AAA between April 2020 and April 2025 were retrospectively analyzed, comparing perioperative mortality and major adverse events between EVAR and OSR.

Results: A total of 494 AAA patients were identified, 49 (9.9%) were symptomatic (40 [81.6%] EVAR group, 9 [18.4%] OSR group). Patients undergoing OSR had a higher rate of juxtarenal involvement (OSR 6/9 [66.7%] vs. EVAR 3/40 [7.5%]; P < 0.001). Any signs of rupture were more prevalent in the EVAR group (27/40 [67.5%] vs. OSR 2/9 [22.2%]; P = 0.013). Technical success was achieved in 83.7% (n=41/49). In-hospital mortality was 22.4% (n=11/49), with no difference between groups (EVAR 9/40 [22.5%] vs. OSR 2/9 [22.2%]; P = 0.986). At logistic regression analysis, open repair was associated with a significantly higher risk of major complications (odds ratio [OR] 16.9, 95% confidence interval [95%CI] 1.79–158.3, P = 0.013), and a shock index > 0.9 remained an independent predictor of intra-hospital mortality (OR 372.5, 95%CI 1.58-87889.4, P = 0.034). During a mean follow-up of 28.8 ± 18.6 months, late mortality was 18.4% (n=7/38). Estimated survival analysis over 60 months did not demonstrate a significant difference between groups (log-rank test, P = 0.317).

Conclusions: Both EVAR and OSR yield satisfactory technical outcomes. Hemodynamic instability at presentation remains a critical predictor of mortality.

A 32-year-old man with Down syndrome (DS), nonverbal due to severe cognitive impairment, presented to the emergency department after sustaining a fall from standing, causing trauma to his left hip. He had no known chronic medication use. His previous medical history included hospitalizations for severe COVID-2019 in 2021 and herpes simplex virus stomatitis in 2017. Following the fall, he was unable to bear weight on the affected limb. On physical examination, his left leg was externally rotated with preserved neurovascular status. Given the mechanism of injury and clinical presentation, non-contrast computed tomography (NCCT) was obtained to assess fractures and underlying pathology [Figure 1A].

Background: Listening to patients and obtaining a thorough history are fundamental in clinical practice. Some pregnant women, particularly in late or preterm gestation, report regular, painful uterine contractions that may not correspond to true labor. In some cases, patients admitted to feigning contractions using the Valsalva maneuver to gain secondary benefits. Misdiagnosing such cases may lead to unnecessary interventions, including iatrogenic prematurity.

Objectives: To explore the phenomenon of pseudo-uterine contractions and assess whether maternal heart rate (HR) can help differentiate them from true contractions.

Methods: We performed a prospective case-crossover study, which included 30 pregnant women in their third trimester who presented to Rambam Health Care Campus. Participants underwent 20 minutes of standard external monitoring followed by 10 minutes of repeated Valsalva maneuvers (every 2 minutes). Maternal and fetal HRs were recorded and compared during baseline, pseudo-, and true contractions.

Results: During pseudo-contractions, maternal HR decreased by approximately 10 bpm (P < 0.001), while fetal HR increased by 8 bpm (P < 0.001). In contrast, true contractions resulted in a maternal HR increase of 15 bpm (P < 0.001) and a fetal HR rise of 12 bpm (P < 0.001).

Conclusions: Maternal HR patterns differ significantly between true and false contractions. A decline in maternal HR during contractions may indicate Valsalva-induced pseudo-contractions, while an increase suggests true labor. This simple observation could aid in preventing unnecessary interventions in suspected cases.

Background: Laparoscopic right hemicolectomy is considered the gold standard surgical treatment for patients with right colon malignancies. The restoration of bowel continuity can be performed by intracorporal (ICA) or extracorporal (ECA) techniques.

Objectives: To evaluate a single-center experience in laparoscopic right colectomy, comparing patients with ICA and ECA.

Methods: This is a case-control retrospective study included all patients who underwent laparoscopic right colectomy between the years 2016–2022 at our medical center. Patients were divided according to the operative technique. The study database included demographics as well as intraoperative and postoperative parameters.

Results: Overall, 125 patients were included in the study, which included 98 patients (78.4%) from the ICA group included and 27 patients in the ECA group. Both groups were comparable in demographics and co-morbidities. No significant differences were observed between the groups in intraoperative complications, length of surgery, return to the oral diet, and length of hospital stay. The incidence of postoperative ventral hernia was significantly higher in patients from the ECA group (18.5% vs. 3.1%, P = 0.012).

Conclusions: Laparoscopic right colectomy with ICA is associated with a lower rate of postoperative ventral hernias.

Methotrexate, a folate analog antimetabolite, is one of the oldest cytotoxic drugs still in use. It is active against a variety of malignancies including bladder and breast cancer, head and neck tumors, gestational choriocarcinoma, osteogenic sarcoma, lymphomas, and leukemias.

Methotrexate is given mostly intravenously (IV), usually at standard doses (milligrams). It can also be delivered in much higher doses (grams), which is known as high-dose methotrexate (HDMTX). The intrathecal (IT) route is used particularly in children with acute lymphoblastic leukemia (ALL) and in adults with meningeal carcinomatosis. The drug may be administered orally as well, mainly in non-oncological conditions such as rheumatoid arthritis and other autoimmune diseases.

Background: The massive terrorist attack on a mixed population of civilians, soldiers, and foreigners on October 7, 2023, resulted in 1200 casualties and led to many major personal identification issues. At the Israel National Center for Forensic Medicine (INCFM), addressing the mass casualty incidents required precision that included technical, ethical, and humanitarian dimensions. Many obstacles arose that were attributable to the vast number and diversity of victims and the heavy workload in the setting of a small forensic team.

Objectives: To define the various methods utilized for victim identification.

Methods: The different types of identification were visual, primary, and circumstantial. Primary methods compared unique and stable characters of the human body, including fingerprints, comparisons of dental data, X-rays, and medical databases. We implemented other methods (anthropology, genetics) and novel creative strategies (digital photography taken by random individuals using mobile phones) and computed tomography (CT) scan at another designated site other than at the INCFM.

Results: Often, visual recognition and extraction of DNA were impossible because of burnt human remains. Hence, a comparison method of antemortem and postmortem CT findings became imperative for many unidentified victims. The more complex cases included the finding of body parts of more than one individual in different body bags (comingled remains). In such situations, we matched the body parts by utilizing DNA methods. We present seven case challenges.

Conclusions: We utilized various known and novel methods for victim identification in the aftermath of the events of 7 October 2023 while addressing ethical issues in a case series.

Background: The use of proprotein convertase subtilisin/kexin type 9 monoclonal antibodies (PCSK9 mAbs) is emerging for lowering low-density lipoprotein cholesterol (LDL-C). However, real-world data is lacking for their use among elderly patients.

Objective: To define the characteristics of elderly patients treated with PCSK9 mAbs and to evaluate the efficacy and tolerability compared with younger patients.

Methods: We conducted a retrospective cohort study of elderly patients (≥ 75 years at enrollment) treated with PCSK9 mAbs for primary and secondary cardiovascular prevention. Data were retrieved for demographic and clinical characteristics; indications for treatment; agents and dosages; concomitant lipid lowering treatment; LDL-C levels at baseline, 6, 12 months, and at the end of follow up. Data also included achieving LDL-C target levels and adverse effects.

Results: The cohort included 91 elderly patients and 92 younger patients, mean age 75.2 ± 3.76 and 58.9 ± 7.4 years (P < 0.0001). Most patients (82%, 80%) were in high/very high-risk categories. For almost all (98%, 99%), the indication was statin intolerance, with PCSK9 mAb monotherapy the most prevalent regimen. The average follow-up was 38.1 ± 20.5 and 30.9 ± 15.8 months (P = 0.0258). Within 6 months the LDL-C levels were reduced by 57% in the elderly group and by 59% in the control group (P = 0.2371). Only 53% and 57% reached their LDL-C target levels. No clinically significant side effects were documented.

Conclusion: PCSK9 mAbs have similar effects and are well tolerated among elderly patients as in younger patients.

On 7 October 2023, a large-scale invasion by armed Hamas terrorists occurred in southern Israel. Approximately 1500 militants breached the Gaza security barrier using tractors, RPGs, and explosives. Concurrently, the terrorists utilized various means including armed vehicles, motorized paragliders, sea incursions, and a massive rocket attack launched toward Israel. On entering Israeli territory, the militants dispersed and targeted several towns, kibbutzim (collective communities), and Israel Defense Forces (IDF) military bases near Gaza. This strategy resulted in a death toll exceeded 1300 civilians and soldiers. In addition, more than 240 individuals were abducted. This attack occurred in one day. In this article, we introduce the Israeli National Institute of Forensic Medicine, which specialized in forensic analysis during mass casualty incidents, and pivotal role it played on 7 October. We present a detailed discussion on methods, challenges, and adaptations the institute took in response to the event of 7 October.

Celiac disease (CD) is an immune-based reaction to dietary gluten. CD can present with a diverse array of symptoms. Many CD patients have no symptoms at all. Thus, a great number of atypical cases of CD remain undiagnosed, leading to a risk of long-term complications. Some atypical symptoms of CD such as pregnancy complications, infertility, recurrent abortions, intrauterine growth restriction, preterm delivery, and severe preeclampsia have been investigated in undiagnosed and diagnosed pregnant women with CD. Nutrient deficiency and autoimmune pathogenic mechanisms have been hypothesized to be the explanation of these adverse pregnancy outcomes. Recently, an association between obstetric complications and anti-tissue transglutaminase antibodies titers in women with CD has been reported. While the adverse effects of CD on the reproductive system are well investigated, there are only a few reports in the literature on the effect of pregnancy and puerperium on CD. We reviewed the published literature on the adverse effects and pathophysiology of CD in reproductive disorders and the effect of pregnancy and puerperium on the manifestation of CD.

Background: The annual incidence of epilepsy increases with age, from nearly 28 per 100,000 by the age of 50 years to 139 per 100,000 by the age of 75 years. Late-onset epilepsy differs from epilepsy at a young age in the prevalence of structural-related epilepsy, types of seizures, duration of seizures, and presentation with status epilepticus.

Objectives: To check the response to treatment in patients with epilepsy with age of onset of 50 years and older.

Methods: We conducted a retrospective study. The cohort included all patients referred to the Rambam epilepsy clinic between 1 November 2016 and 31 January 2018 with epilepsy onset at age 50 years or older and at least one year of follow-up at the recruitment time point and epilepsy not caused by a rapidly progressive disease.

Results: At recruitment, most patients were being treated with a single antiseizure medication (ASM); 9 of 57 patients (15.7%) met the criteria for drug-resistant epilepsy (DRE). The mean duration of follow-up was 2.8 ± 1.3 years. In an intention-to-treat analysis, 7 of 57 patients (12.2%) had DRE at the last follow-up.

Conclusions: Late-onset epilepsy, which is defined as a first diagnosis in patients older than 50 years of age, is easy to control with monotherapy. The percentage of DRE in this group of patients is relatively low and stable over time.

Background: The two cerebral hemispheres influence the immune response differently. While the left hemisphere enhances cellular immunity, the right hemisphere inhibits it.

Objectives: To determine whether immune and inflammatory markers correlated with stroke severity and hospitalization duration as a function of stroke side.

Methods: The study included 137 patients with unilateral ischemic stroke. The medical records were reviewed for demographic and clinical laboratory data, including C-reactive protein (CRP), white blood cell (WBC) count, its differential stroke side and stroke severity according to the National Institute of Health Stroke Scale (NIHSS), and length of hospital stay (LOS). We examined differences between right side (RS) and left side (LS) stroke on immune and inflammatory markers and compared correlations between these markers and NIHSS and LOS as a function of stroke side.

Results: RS stroke patients had higher CRP and monocytes than LS stroke patients. In RS stroke patients, CRP, total WBC, and lymphocyte levels positively correlated with both NIHSS and LOS, whereas levels of neutrophils were positively correlated with NIHSS alone. No correlations were found for LS stroke patients.

Conclusions: Immune-inflammatory markers correlated with stroke severity and LOS only in patients with RS stroke. Neuroimmunological processes influence short-term clinical outcomes after stroke, especially considering the differential effects of the hemispheres on immunity. Prospective studies that evaluate long-term clinical outcomes are needed. Testing the effects of anti-inflammatory treatments on prognosis of RS stroke patients should be considered.

Late, preterm premature rupture of the membranes (PPROM) presents a major obstetrical challenge balancing between iatrogenic prematurity and risk of prolonged rupture of membranes. In recent years, the pendulum has been shifting toward expectant management until gestation week 37 + 0. We examined the latest guidelines and major trials and summarized optimal management. We addressed the major dilemmas of women with PPROM during gestation weeks 34 + 0 to 36 + 6.

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia. Previous studies showed that rhythm and rate control strategies are associated with similar rates of mortality and serious morbidity. Beta blockers (BB) and calcium channel blockers (CCB) are commonly used and the selection between these two medications depends on personal preference.

Objectives: To compare real-time capability of BB and CCB for the treatment of rapid AF and to estimate their efficacy in reducing hospitalization duration.

Methods: We conducted a retrospective cohort study of 306 patients hospitalized at Soroka Hospital during a 5-year period with new onset AF who were treated by a rate control strategy.

Results: A significant difference between the two groups regarding the time (in hours) until reaching a target heart rate below 100 beats/min was observed. BB were found to decrease the heart rate after 5 hours (range 4–14) vs. 8 hours (range 4–18) for CCB (P = 0.009). Patients diagnosed with new-onset AF exhibited shorter duration of hospitalization after therapy with BB compared to CCB (median 72 vs. 96 hours, P = 0.012) in the subgroup of patients discharged with persistent AF. There was no significant difference between CCB and BB regarding the duration of hospitalization (P = 0.4) in the total patient population.

Conclusions: BB therapy is more potent for rapid reduction of the heart rate compared to CCB and demonstrated better efficiency in shortening the duration of hospitalization in a subgroup of patients. This finding should be reevaluated in subsequent research.

Background: Chest trauma is among the most common types of trauma, corresponding to 10% of trauma patients admitted to hospitals. In the military setting, thoracic trauma was reported as a significant cause of death. With well-timed treatment, chest trauma is regarded as survivable. Emergency thoracotomy (ET) is considered when the patient with trauma to the chest needs immediate resuscitation. Survival rate is reported as low as 1% in some reports and 20% in others. The survival rate depends on injury mechanism, protocols for intervention, and other decompressive procedures.

Objectives: To determine parameters that may impact survival of ET.

Methods: We conducted a retrospective cohort study to compare prehospital and in-hospital data regarding ET in the emergency department (ED) versus the operating room (OR).

Results: Between 2009 and 2017, 6532 casualties presented to the ED; 1125 with trauma to the chest. Fifty-four of those with chest trauma underwent ET in the hospital (4.8%), 22 (41%) in the ED, and 32 (59%) in the OR. The overall mortality of the ET subgroup was 48%. With regard to thoracotomies, 19/22 of patients (86%) who underwent ET in the ED died compared to 2/28 in the OR (13%).

Conclusions: Utilizing ET after chest trauma with appropriate clinical indications, well-trained personnel, and prompt transportation poses a significant challenge, but may be associated with better survival than that reported previously with military casualties. Adoption of indications and timed allocation to the OR may improve outcomes with chest trauma casualties.

Background: Traumatic brain injury (TBI) is a significant cause of death in the battlefield. TBI can be challenging to diagnose in the combat setting and remains a substantial challenge for advanced life support (ALS) providers.

Objectives: To compare prehospital and hospitalization characteristics between isolated and non-isolated TBI. To examine the effects of TBI with coexisting injuries on patient evaluation and outcomes based on the Israeli Defense Forces Trauma Registry and the Israeli National Trauma Registry of soldiers hospitalized for TBI between the years 2006–2017.

Methods: A total of 885 casualties were eligible for our study, of whom 271 (30%) had isolated TBI. Only 35% of hospitalized patients with isolated TBI were defined as urgent by the ALS providers versus 67% in the non-isolated TBI group (P < 0.001).

Results: Overall, 29% of the TBIs in the non-isolated group were missed by the ALS providers vs. 11% in the isolated group.

Conclusions: Concomitant injuries may delay the diagnosis of TBI by ALS providers. These findings should be considered in the prehospital evaluation to potentially improve the care and outcome of head injury patients.
