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.

The ancient, Biblical, holy Ten Commandments were presented to humanity to serve as guidelines for relationships between individuals and the deity they worship as well as a benchmark for living in civilized communities, irrespective of religious affiliation. The commandments are also embedded in medical education taught to medical students and other health professions throughout the world. Thus, the Ten Commandments are embedded in the medical communications curriculum at Adelson School of Medicine, Ariel University, Ariel, Israel. Unfortunately, most of these commandments were desecrated during the violent, hostile, merciless, and ruthless attack inflicted by the Hamas terror organization on villages, rural communities, and cities in southern Israel on 7 October 2023. We define the Ten Commandments in terms of medical education and describe their desecration by Hamas terrorists before and during the Iron Swords war.

Chronic obstructive pulmonary disease (COPD) is a common lung disease characterized by restricted airflow, changes of lung tissues, and breathing difficulties [1]. Most patients are treated at home to maintain a stable lifestyle and quality of life [2].

An important feature of COPD is exacerbation, which is an acute worsening of symptoms that can result in decreased pulmonary functions, increased risk of death, and poorer quality of life. The frequency and severity of each exacerbation results in further worsening of pulmonary function [3]. Depression in COPD patients may cause objective impairment in function and decreased adherence to therapeutic interventions [4].

Acute stress disorder is characterized by acute reaction in the first month following exposure to a traumatic event such as threatened death, serious injury, or sexual assault. Symptoms include intrusion, dissociation, negative mood avoidance, and arousal [5]. Stress on a more continuous basis can significantly debilitate a person's emotional and physical wellbeing, lead to depression and weakened immune system, and influence patients with already stressful and progressive conditions such as COPD.

We present a patient previously diagnosed with COPD who experienced an acute terror attack, which was a major and stressful event that caused severe exacerbation of the disease.

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: Hip fractures are a public health problem that disproportionately affects the elderly. Displaced femoral neck fractures were treated historically with hemiarthroplasty, but the use of total hip arthroplasty (THA) is increasing showing superior long-term results.

Objectives: To assess whether THA has superior short-term results compared to bipolar hemiarthroplasty for displaced femoral neck fractures.

Methods: Two groups of active older patients underwent either cementless bipolar hemiarthroplasty or THA for displaced femoral neck fracture. All patients were operated on using the direct lateral approach to the hip joint. Patients were assessed using the Harris Hip Score at hospital discharge and at 6 weeks follow-up.

Results: We included 40 patients ages 65–85 years; 18 underwent bipolar hemiarthroplasty and 22 THA. The number of women in each group was similar, as was mean age: 73.1 ± 4.2 years in the hemiarthroplasty group and 71.0 ± 3.7 in THA. Harris Hip Score on hospital discharge was similar in both groups. Walking ability at discharge was better in the THA cohort and they were discharged sooner: 5.2 ± 1.3 vs. 6.4 ± 1.7 days following hemiarthroplasty (P = 0.021). At 6 weeks follow-up, the mean Harris Hip Score was higher in the THA group (78.6 ± 11 vs. 61.5 ± 17 for hemiarthroplasty, P < 0.001). Patients in the THA group walked longer distances, needed less support while walking, and reported less pain.

Conclusions: Better short-term results at hospital discharge and at 6 weeks follow-up after THA contributed to earlier patient independence and shorter hospital stays.

Background: With age, colorectal cancer (CRC) prevalence rises. The elderly (> 75 years), and the very elderly (> 85 years) are especially vulnerable. The advantages of screening must be assessed in the context of diminished life span and co-morbidities.

Objective: To compare CRC findings in colonoscopies that were performed following a positive fecal occult blood test/fecal immunochemical test (FOBT/FIT) in both elderly and very elderly age groups with those of younger patients.

Methods: We identified colonoscopies conducted between 1998 and 2019 following a positive stool test for occult blood in asymptomatic individuals. A finding of malignancy was compared between the two patient age groups. Furthermore, a sub-analysis was performed for positive malignancy findings in FOBT/FIT among patients > 85 years compared to younger than < 75 years.

Results: We compared the colonoscopy findings in 10,472 patients: 40–75 years old (n=10,146) vs. 76–110 years old (n=326). There was no significant difference in prevalence of CRC detection rate between the groups following positive FOBT/FIT (2.1% vs. 2.7%, P = 0.47). Similar results for non-significant differences were obtained in the sub-analysis compared to malignancy detection rates in the very elderly 0% (n=0) vs. 2.1% for < 75 years old (n=18), P = 0.59.

Conclusions: Although the prevalence of CRC increases with age, no significant increase in the detection rate of CRC by FOBT was found in either the elderly or very elderly age groups. Screening colonoscopies in elderly patients should be performed only after careful consideration of potential benefits, risks, and patient preferences.

Background: Ventricular assist devices (VADs) play a critical and increasing role in treating end-stage heart failure in pediatric patients. A growing number of patients are supported by VADs as a bridge to heart transplantation. Experience with VADs in the pediatric population is limited, and experience in Israel has not been published.

Objectives: To describe this life-saving technology and our experience with VAD implantation in children with heart failure, including characteristics and outcomes.

Methods: We conducted a retrospective chart review of all patients who underwent VAD implantation at Schneider Children's Medical Center from 2018 to 2023.

Results: We analyzed results of 15 children who underwent VAD implantation. The youngest was 2.5 years old and weighed 11 kg at implantation. In eight patients, HeartMate 3, a continuous-flow device, was implanted. Seven patients received Berlin Heart, a pulsatile-flow device. Three children required biventricular support; 11 underwent heart transplants after a median duration of 169 days. Two patients died due to complications while awaiting a transplant; two were still on VAD support at the time of submission of this article. Successful VAD support was achieved in 86.6% of patients. In the last 5 years,79%  of our heart transplant patients received VAD support prior to transplant.

Conclusions: Circulatory assist devices are an excellent bridge to transplantation for pediatric patients reaching end-stage heart failure. VADs should be carefully selected, and implantation techniques tailored to patient's weight and diagnosis at a centralized pediatric cardiac transplantation center. Israeli healthcare providers should be cognizant of this therapeutic alternative.

Metastatic spinal cord compression (MSCC) is a medical emergency requiring rapid diagnosis and intervention to avoid irreversible neurological damage [1]. While MSCC is best diagnosed by magnetic resonance imaging (MRI), this modality is often limited and is usually preceded by a computed tomography (CT) scan of the spine.

Anti-tumor necrosis factor-alpha (anti-TNFα) medications are the most frequently used biologicals to treat inflammatory bowel disease (IBD). Little is known about the ocular side effects of this drug category. We present a case series of six young patients with Crohn disease (CD) and no previous ophthalmologic manifestations who developed blepharitis after commencing treatment with anti-TNFα therapy. Six otherwise healthy patients with CD, with no history of allergies or prior ocular complaints, developed blepharitis at a median of 7.5 months after the initiation of anti-TNFα therapy. All ophthalmic findings were treated topically. The ocular symptoms of two of the patients resolved shortly after discontinuation of the anti-TNFα treatment. The other four presented with relapsing-remitting symptoms. Blepharitis is a common ocular disease in the general population and an extra-intestinal manifestation in patients with IBD. It may be an adverse effect of anti-TNFα therapy in this patient population.

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: Younger patient age and relatively good prognosis have been described as factors that may increase caregiver motivation in treating patients with septic shock in the intensive care unit (ICU).

Objectives: To examine whether clinical teams tended to achieve unnecessarily higher map arterial pressure (MAP) values in younger patients.

Methods: We conducted a population-based retrospective cohort study of patients presenting with septic shock who were treated with noradrenaline and hospitalized in a general ICU between 2006 and 2018. The patients were classified into four age groups: 18-45 (n=129), 46-60 (n=96), 61-75 (n=157), and older than 75 years (n=173). Adjusted linear mixed models and locally weighted scatterplot smoothing (LOWESS) curves were used to assess associations and potential non-linear relationships, respectively, of age group with MAP and noradrenaline dosage.

Results: The cohort included 555 patients. An inverse relation was observed between average MAP value and age. Among patients aged 18–45 years, the average MAP was 4.7 mmHg higher (95% confidence interval 3.4–5.9) than among patients aged > 75 years (P-value <0.001) after adjustment for sex, death in the intensive care unit, and Sequential Organ Failure Assessment scores.

Conclusions: Among patients with septic shock, the titration of noradrenaline by staff led to a higher average MAP for younger patients. Although the MAP target is equal for all age groups, staff may administer noradrenaline treatment according to a higher target of MAP due to attitudes toward patients of different ages, despite any evidence that such practice is beneficial.

Background: The continuity equation (CE) used for evaluating aortic stenosis (AS) is based on values obtained from transthoracic echocardiography (TTE) with the assumption that the left ventricular outflow tract (LVOT) has a circular shape. Transesophageal echocardiography (TEE) may be used for accurate measurement of the LVOT cross-sectional area (CSA). Previous studies have focused on fusion from TEE for LVOT-CSA measurement and TTE for velocity time integrals (VTI) calculations.

Objectives: To assess aortic valve area (AVA) using parameters obtained exclusively from TEE as an alternative approach.

Methods: Thirty patients with equivocal AS based on TTE were evaluated using TEE for further assessment.

Results: The mean pressure gradient across the aortic valve (AV) was 38 ± 5.9 and 37.9 ± 7.6 mmHg in TTE and TEE, respectively, P = 0.42. LVOT-CSA was larger in TEE (3.6 ± 0.3 vs. 3.4 ± 0.3 cm², P = 0.049). VTI over the AVA was similar (98.54 ± 22.8 and 99.52 ± 24.52 cm in TTE and TEE, respectively, P = 0.608), while VTI across the LVOT was higher when measured by TTE (24.06 ± 5.8 vs. 22.03 ± 4.3 cm, P < 0.009). Using the CE, AVA was 0.82 ± 0.3 vs. 0.83 ± 0.17 cm² in TEE vs. TTE, respectively, P = 0.608. Definitive grading was achieved in all patients (26 patients defined with severe AS and 4 with moderate).

Conclusions: In equivocal cases of AS, full assessment using TEE may be a reliable modality for decision making.

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.

A 42-year-old healthy man collapsed suddenly in the street while walking. The patient received 2 minutes of basic life support until an automatic external defibrillator was brought and detected ventricular fibrillation (VF), which was successfully terminated by a single shock. The patient regained consciousness and was transferred to the hospital.

The patient’s physical examination was normal with no neurologic deficit. Blood pressure was 147/102 mmHg. Brain computed tomography showed normal findings. The first troponin I measurement within 1 hour of the event was in the normal range (19.6 ng/L, normal < 20 ng/L) and rose to 99.9 ng/L after 3 hours.

Status epilepticus (SE) is a neurological emergency requiring immediate evaluation and management to prevent significant morbidity or mortality. Previously, status epilepticus was defined as a seizure with a duration equal to or greater than 30 minutes or a series of seizures in which the patient does not regain normal mental status between seizures. The Neurocritical Care Society guidelines from 2012 revised the definition to a seizure with 5 minutes or more of continuous clinical and/or electrographic seizure activity or recurrent seizure activity without recovery between seizures.

Status epilepticus may be convulsive, non-convulsive, focal motor, or myoclonic, and any can become refractory. Convulsive status epilepticus consists of generalized tonic-clonic movements and mental status impairment. Non-convulsive status epilepticus is defined as seizure activity identified on an electroencephalogram with no accompanying tonic-clonic movements. Focal motor status epilepticus involves the refractory motor activity of a limb or a group of muscles on one side of the body with or without loss of consciousness. Refractory status epilepticus refers to continuing seizures (convulsive or non-convulsive) despite appropriate antiepileptic drugs [1].
