The Nazi regime occupying Europe during World War II built a series of concentration camps for those opposing the regime, political and criminal adversaries, and eventually victims of the racial, Aryan policy. It was the suggestion of Germany's elite physician to the Schutzstaffel (SS), Reichfuehrer H.H. (Heinrich Luitpold Himmler), to use the available workforce in the camps, before their eventual liquidation [2,3]. What was the outcome?

The SS medical services in the Auschwitz concentration camp functioned based on two mutually exclusive principles. On the one hand, medical care was provided for the SS staff, and on the other hand, prisoners with contagious diseases or in the terminal stages of exhaustion were eliminated.

Background: Botulinum toxin (BT) can alleviate limb dystonia, but limited insurance coverage hinders its utilization.

Objectives: To compare the therapeutic efficacy of BT injections for spasticity and dystonia of the limbs.

Methods: BT injections of hypertonic limbs were administered under ultrasound guidance between 2019 and 2024 for either limb dystonia or limb spasticity.

Results: Of 74 patients included, 57 were diagnosed with spasticity and 17 with dystonia. In total, 276 therapeutic cycles were administered. The dropout rates were 45.6% in the spasticity group and 41.2% in the dystonia group (P = 0.48). There was no significant difference in subjective motor improvement between dystonia and spasticity (P = 0.16). Dystonia patients reported significantly better pain relief (98.5 ± 4.9% vs. 72.4 ± 35.6% respectively, P < 0.001). Notably, 74.3% of dystonia treatments reported moderate or marked improvement, whereas only 54.0% of spasticity treatments did (P > 0.05), based on patient the global impression of change (PGI-C) scale. Side effects were infrequent.

Conclusions: BT injections for limb spasticity and dystonia are partially effective. Nonetheless, the dropout rate is high. While BT injections are more effective in relieving pain for dystonia compared to spasticity, disease severity gradually improves over time in treated patients with spasticity but not with dystonia.

Background: Several studies have shown an association between increased red blood cell distribution width (RDW) and adverse outcomes in various acute diseases. Small studies have suggested that RDW is a useful predictor of acute pancreatitis severity.

Objectives: To determine the association between RDW at admission and early mortality in acute pancreatitis. To assess whether RDW adds to the predictive ability of the Glasgow Imrie Score.

Methods: In this observational study, we included all adult patients admitted with a primary diagnosis of acute pancreatitis between January 2008 and June 2021. Patients were divided into two groups according to RDW: normal RDW (RDW ≤ 14.5%) and elevated RDW (RDW > 14.5%).

Results: Within 30 days of admission, 29/438 patients (6.6%) with increased RDW and 20/1250 patients (1.6%) with normal RDW had died: univariate analysis (odds ratio 4.6, 95% confidence interval 2.45–7.9, P < 0.001), fully adjusted model (odds ratio 3.29, 95% confidence interval 1.75–6.26, P < 0.001). We calculated receiver operating characteristic curve (ROC) for RDW alone, Glasgow Imrie Score alone, and a combination of Glasgow Imrie Score with RDW. We assessed their ability to predict 30-day mortality. Area under the ROC curve (AUC) of RDW alone was 0.671 and Glasgow Imrie Score AUC was 0.682; Glasgow Imrie Score plus RDW had an AUC of 0.769.

Conclusions: In patients with acute pancreatitis, elevated RDW at admission was independently associated with increased 30-day mortality. The addition of RDW to a pancreatitis prognostic tool such as the Glasgow Imrie Score improves its predictive ability.

On 9 August 1938, prisoners from Dachau concentration camp near Munich were sent to the town of Mauthausen in Austria to begin building a new camp. The site was chosen because of the nearby granite quarry and its proximity to Linz [1,2].

Mauthausen initially served as a prison camp for common criminals, prostitutes, and other categories of incorrigible law offenders. However, on 8 May 1939, it was converted to a labor camp. Later, Mauthausen KL became a Nazi concentration camp on a hill above the market town of Mauthausen, approximately 20 kilometers from Linz. It was complemented with dozens of subcamps in the surrounding areas.

Background: On 7 October 2023, an armed conflict erupted between Hamas and Israel, leading to numerous combat casualties.

Objectives: To describe computed tomography (CT) findings of combat casualties at a tertiary medical center during the first 3 months of the conflict.

Methods: A retrospective observational study was conducted on patients admitted between 7 October 2023 and 7 January 2024. Adults with conflict-related trauma who underwent chest, abdomen, and pelvis (body) trauma protocol CT scans were included.

Results: Of 272 patients who underwent body trauma protocol CT, 112 combat-related adults were included, mean age of 27 years and one female. In total, 82 patients (73%) underwent additional scans of the head and neck or extremities. Fractures were observed in 53 patients (47%). Vascular injuries were present in 40 patients (35%). Limb injuries were most common, affecting 37 patients (33%), which prompted a protocol update. Lung injuries were the most common in body CT: 30 patients (27%). Head and neck injuries were seen in 21 patients (18%). Multisystem trauma was present in 24 patients (21%). A total of 83 patients (74%) underwent surgery, mostly orthopedic/soft tissue surgeries (63%); 15 (13%) underwent abdominal surgery, with bowel injuries confirmed in eight cases.

Conclusions: CT scans are an important tool in conflict trauma management. Limb injuries were the most frequent, necessitating protocol adjustments. Lung injuries were the most common body injury; 21% of patients had multisystem trauma. Most patients required surgery.

The Dina Recanati School of Medicine at Reichman University offers a unique approach to preclinical medical education, combining strong scientific foundations with practical, clinical applications. This 4-year program includes two preclinical years focused on core medical knowledge and two clinical years of rotations. The curriculum emphasizes small-group learning, early clinical exposure, and a system-based block structure. Starting from the first week of the preclinical years, students will participate in biweekly clinical days, using simulations, virtual reality, and patient interactions to develop practical clinical skills. The community clinic mentorship offers real-world experience that complements the clinical program taught in class during the same week. Research is central, with students conducting supervised projects aimed at a medical doctor thesis publication. The teaching model ensures relevance by integrating clinical cases into all courses, guided by practicing physicians. Daily quizzes and block-style assessments replace traditional examination periods, promoting consistent learning. The innovative program balances clinical practice with scientific knowledge, preparing students for the challenges of modern medicine.

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with heart failure (HF) secondary to left ventricular systolic dysfunction (defined as left ventricular ejection fraction [LVEF]) < 45% toward the end of pregnancy or in the months following delivery, where no other cause of HF is found. Complete understanding of the etiology is lacking, with higher incidence seen in advanced maternal age, multiple gestations, preeclampsia, and anemia [1]. Potential suggested causes include pathological immune response, hormonal abnormalities, stress cytokines, and nutritional deficiencies. Genetic predisposition was demonstrated in some PPCM, most commonly pathogenic loss-of-function truncating variants in Titin gene (TTN) [1]. Other causative genes reported are DMD, LAMP2, DSP, MYH6, SYNM, TPM1, and VCL [1].

Background: The impact of the coronavirus disease 2019 (COVID-19) pandemic on patient populations can be divided to direct consequences of the disease and indirect implications of changes imposed on the national healthcare systems. The impact of the later survival of chronic hemodialysis patients is still unknown.

Objectives: To examine the impact of quarantine on health outcomes of dialysis patients.

Methods: In a retrospective case-controlled study, we compared chronic hemodialysis patients from two separate timeframes: during a quarantine period and a parallel time without quarantine.

Results: The study included 344 hemodialysis patients. Baseline characteristics were compared between those enrolled in 2015 and those enrolled in 2020. Despite comparable clinical parameters, a statistically significant increase in the 6-month mortality rate was observed in 2020 (1.2% vs. 6.7%, P = 0.01), primarily attributed to sepsis. Notably, no deaths were attributed to COVID-19 in 2020. Interdialytic weight gain and dialysis quality remained similar between the two groups, with a mild trend toward excessive weight gain in 2020. Secondary outcomes after 6 months did not significantly differ, except for lower sodium values in 2015 compared to 2020.

Conclusions: Dialysis patients experienced disproportionate effects from the COVID-19 pandemic, even with continuous care and no direct virus-related fatalities. The findings showed unintended consequences of quarantine measures, highlighting adverse impact on both physical and mental health. Recognizing and addressing these consequences are imperative for minimizing their impact in future pandemics, emphasizing the importance of proactive measures in healthcare planning.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive, soft-tissue sarcoma. The treatment is surgical and includes wide local excision (WLE) or Mohs micrographic Surgery (MMS). There is no consensus regarding the preferred type of surgery.

Objectives: To compare the outcomes of the two types of surgery (WLE and MMS).

Methods: This retrospective cohort study was based on the medical records of 59 patients with DFSP treated at Sheba Medical Center (using the WLE method) or Assuta Medical Center (using the MMS method) between 1995 and 2018. The data included demographics, clinical presentations, imaging, types of wound closures, pathological margin status, surgical defect sizes, recurrences, and follow-up.

Results: Of the 59 included patients, 18 (30.5%) underwent WLE and 41 (69.5%) underwent MMS. The mean age at diagnosis was 40.1 ± 14.4 years. The male-to-female ratio was 1.5:1. The main tumor location was the trunk (50% for WLE and 41.5% for MMS). The main type of closure for both procedures was primary closure. In 72.2% of WLE and 78.8% of MMS cases, the margins were free. The difference between the final surgical defect and the original tumor size was statistically significantly smaller in patients who underwent MMS. The median duration of follow-up was 6.6 years. There was no significant difference in the rate of recurrence.

Conclusions: MMS enables better tissue preservation and results in a minor surgical defect compared to WLE, with no difference in tumor recurrence between the two methods.

Background: One of the major causes of reversible visual impairment is a refractive error, which can be corrected through refractive surgery. Data regarding the outcomes and complications of these procedures exist; however, there is a notable gap in understanding the factors leading to patient rejection, particularly in diverse populations like Israel.

Objectives: To detect clinical risk factors of patients who intend to undergo LASIK procedure and to improve the conversion rates of LASIK procedure in this population.

Methods: The study included a retrospective analysis of patients who were rejected from having refractive surgery in two Enaim Refractive Surgery Centers: Jerusalem and Tel Aviv. Comparisons between centers were conducted using the t-test for continuous variables and Fisher's exact test for categorical data.

Results: Our study included 337 patients who were rejected from having refractive surgery, including 152 (45.1%) who were rejected permanently and 185 (54.9%) rejected temporarily. The most common reasons for permanent rejection were corneal irregularity (n=81, 53.3%), keratoconus (n=27, 17.8%), thin corneas (n=13, 8.6%), and amblyopia (n=10, 6.6%). The most common temporary reasons were unstable refraction (n=96, 51.9%), prolonged use of contact lenses (n=54, 29.2%), and corneal irregularity (n=16, 8.6%).

Conclusions: The leading permanent cause of rejection for refractive surgery was a corneal irregularity, whereas the primary temporary cause was unstable refraction. In a time of rapid technological advancements and growing demand for freedom from glasses, there is an increasing need for more informed and patient-focused refractive correction approaches.

Takotsubo cardiomyopathy (TC) is a temporary and reversible hypokinesia of the left ventricle's apical area of the heart mediating systolic abnormality. This phenomenon resembles myocardial infarction but without coronary artery disease (CAD) [1]. The prevalence is 1.0–2.5% annually. Most of the patients with TC are postmenopausal women [2]. Over-stimulation of the sympathetic system, microvascular and myocardial tissue metabolism abnormality, and coronary artery vasospasm are linked to TC [2]. The criterion of the diagnosis consists of temporary hypokinesis or akinesis in left ventricle segments with or without apical involvement, electrocardiogram (ST-segment elevation and/or T-wave inversion), or significant elevation of serum cardiac troponins and non-existence of pheochromocytoma or myocarditis [3]. The pathognomonic finding of TC during echocardiography is apical ballooning involving the left ventricle. This unique morphology was reported to present in 75% of patients [2,3]. In 25% of patients. The morphology was reported to follow a mid-ventricular ballooning pattern due to mid-LV akinesis with no disturbance of apical and basal contraction [2,3].

Almost three-quarters of a century ago an American surgeon named Frederick Edward Mohs, had the idea of excising skin cancers and examining the margins before the closure of the surgical wound. In this manner he thought the patient would get better treatment with the best cosmetic result.

Mohs micrographic surgery (MMS) in its present format has been used as a surgical method for treating skin cancers for the last 70 years. The method became popular with American dermatologists 54 years ago when the original Mohs technique was modified into its fresh tissue modality [2] and in the rest of the Western world and Israel more than 35 years ago. Variations of MMS started to appear and indications for surgery also expanded. At the beginning, MMS was indicated mainly for basal and squamous cell carcinomas–nonmelanoma skin cancers (NMSC). Knowledge has been collected and today the method is applicable for a variety of other skin cancers such as melanoma in situ, microcystic adnexal carcinoma, dermatofibrosarcoma protuberans (DFSP), and other adnexal and spindle cell tumors. In this issue of the Israel Medical Association Journal (IMAJ), Landov and colleagues [3] showed the value of MMS for the treatment of DFSP.

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: Military medicine has evolved significantly over the past 50 years, advancing from basic treatments and limited evacuations to sophisticated combat casualty care. Innovations such as hemorrhage control, early blood product administration, and telemedicine have greatly improved battlefield care. Rapid evacuation systems and skilled medical teams have reduced mortality and morbidity rates.

Objectives: To review the transformation of the Israel Defense Forces Medical Corps (IDF-MC) in combat casualty care over the past 50 years, focusing on recent applications during the Iron Swords war.

Methods: Data were collected from the personal experiences of IDF-MC doctors, IDF archives, and relevant military medical literature, with an emphasis on life-saving strategies, personnel, equipment, mental health support, and civil–military cooperation.

Results: Rapid evacuation and immediate care have improved survival rates, while increased front-line deployment of medical staff has enhanced response capabilities. Modern medical tools and techniques, such as tourniquets and blood products, have been widely adopted. Improved psychological support strategies ensure better mental health outcomes for soldiers. Enhanced coordination with civilian trauma systems optimizes care and resource allocation, leading to more efficient and effective casualty treatment.

Conclusions: The IDF-MC's advancements in rapid evacuation and front-line medical support have significantly improved combat casualty outcomes. Continued innovation and collaboration with civilian systems are essential for further progress in military medicine. Future technological advancements are anticipated to further enhance military medical care.
