A full-term 1-month-old female was brought to our pediatric emergency department (ED) due to 3 days of increasing respiratory distress. She was born at term to healthy, consanguineous (2nd degree) Bedouin parents after a pregnancy that lacked adequate monitoring. At birth, a physical examination revealed an imperforate anus and a recto-vestibular fistula, left hydronephrosis, large patent ductus arteriosus (PDA), and an atrial septal defect (ASD). The diagnosis of VACTER association was made. Importantly, she had no respiratory difficulties, nor hemivertebra or tethered cord.

On admission to the ED, she presented with severe respiratory distress, tachypnea, dyspnea, and hypoxemia without evidence of upper airway obstruction or stridor. Due to impending respiratory failure, she was transferred to the pediatric intensive care unit and started on non-invasive respiratory support through a high-flow nasal cannula (HFNC), which partially relieved her work of breathing. The nasal swab for respiratory viruses was positive for enterovirus, and her urine culture grew Escherichia coli. She was transferred to the pediatric ward after clinical improvement on day 3. Echocardiography performed for evaluation of pulmonary hypertension estimated normal pressures but revealed a vascular ring anomaly. A computed tomography (CT) angiography performed confirmed the presence of an aberrant left pulmonary artery also referred to as a left pulmonary artery sling (LPAS) [Figure 1A].

Anorexia nervosa (AN) is a common psychiatric disorder primarily affecting adolescents and young adults. It is characterized by extreme restriction of food intake, distorted body image, and weight-gain anxiety. We report a case with rapid progression and severe metabolic changes in a young restrictive-type AN patient, highlighting unique aspects of this presentation and discussing pathophysiology.

An 11-year-old girl presented with a significant 29% weight loss over 4 months, leading to a body mass index (BMI) of 11.7 (< 1st BMI percentile for her sex and age). She presented with severe bradycardia and metabolic abnormalities including hypoglycemia, hypercholesterolemia, and hypothyroidism. Following diagnosis with restrictive type AN based on the DSM-5 [1] criteria and stabilization at our department, she was transferred to a specialized unit. The hypercholesterolemia our patient presented with is more typical of binge-eating/purging subtype AN, yet it was markedly elevated in this restrictive-type case.

Artificial Intelligence (AI), particularly large language models (LLMs) like OpenAI's ChatGPT, has shown potential in various medical fields, including pediatrics. We evaluated the utility and integration of LLMs in pediatric medicine. We conducted a search in PubMed using specific keywords related to LLMs and pediatric care. Studies were included if they assessed LLMs in pediatric settings, were published in English, peer-reviewed, and reported measurable outcomes. Sixteen studies spanning pediatric sub-specialties such as ophthalmology, cardiology, otology, and emergency medicine were analyzed. The findings indicate that LLMs provide valuable diagnostic support and information management. However, their performance varied, with limitations in complex clinical scenarios and decision-making. Despite excelling in tasks requiring data summarization and basic information delivery, the effectiveness of the models in nuanced clinical decision-making was restricted. LLMs, including ChatGPT, show promise in enhancing pediatric medical care but exhibit inconsistent performance in complex clinical situations. This finding underscores the importance of continuous human oversight. Future integration of LLMs into clinical practice should be approached with caution to ensure they supplement, rather than supplant, expert medical judgment.

Inborn errors of immunity (IEI), formerly known as primary immunodeficiencies (PID), comprise a diverse group of genetic disorders characterized by increased susceptibility to infections, autoimmunity, autoinflammatory conditions, allergies, and malignancies. These disorders exhibit a broad spectrum of clinical manifestations, including extra-hematopoietic manifestations, which may also present later in life. IEI diagnosis has significantly advanced, in line with the common use of next-generation sequencing-based genetic platforms, such as whole-exome and whole-genome sequencing. Treatment approaches have evolved beyond infection management to include curative therapies such as hematopoietic stem cell transplantation, gene therapy, and targeted pharmacologic treatments. In this review, we explore recent advancements in the understanding, diagnosis, and treatment of IEI, emphasizing the rapid progress in this expanding field.

Background: Coronavirus disease 2019 (COVID-19) is a respiratory illness with broad spectrum of clinical manifestations ranging from asymptomatic cases to severe complications such as acute respiratory failure, multi-organ dysfunction, and death.

Objectives: To evaluate the platelet-lymphocyte ratio (PLR) as a marker of disease severity and mortality in COVID-19 patients. To explore the relationship between PLR and other inflammatory indicators, specifically C-reactive protein (CRP) and neutrophil-lymphocyte ratio (NLR).

Methods: The cohort included 400 patients (206 males, 194 females; mean age: 64.5 ± 17.1 years [range 20–100 years]) who were hospitalized between April 2020 and December 2021. Data were collected on demographic and clinical characteristics, including ward and critical care details. CRP, NLR, and PLR values were recorded on the first and last days of hospitalization. Patients were categorized based on their hospitalization outcomes.

Results: PLR statistically increased during hospitalization, from 245 ± 160 at admission to 341 ± 747 at discharge (P < 0.001). A significant association was found between PLR and both the length of hospital stay and mortality. The mean PLR in the deceased group was 445 ± 590, compared to 304 ± 795 in the survivors, P = 0.007. This finding showed a correlation between higher PLR and increased severity and mortality.

Conclusion: PLR has been identified as a relevant marker for assessing the severity of COVID-19. Elevated PLR levels are associated with cytokine storm, length of hospital stay, and mortality. The results highlight the relationship between elevated PLR and poor outcome in COVID‐19 patients, suggesting its use in monitoring disease progression and prognosis.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease pathway is heavily influenced by different inflammatory cytokines. There is ample evidence of cannabidiol (CBD) immunomodulation effects.

Objectives: To investigate the effect of CBD on patients with SARS-CoV-2 and to measure the impact on inflammatory cytokines.

Methods: A double blind, placebo-controlled study to compare the clinical outcomes and selected serum cytokine levels in patients with SARS-CoV-2 that received sublingual CBD extraction. Seven patients were randomized to the treatment arm and three to the placebo group.

Results: Clinical outcomes were better in the patient group that received sublingual CBD vs. patients receiving placebo treatment. Serum cytokine mean concentration levels showed differences between the two groups but of mixed trends.

Conclusions: Patients presenting with SARS-CoV-2 and receiving CBD sublingually had better outcomes than those receiving a placebo, although these results did not reflect in selected serum cytokines. Further study is needed.

Background: Giant cell arteritis (GCA) is a large vessel vasculitis predominantly affecting patients over 50 years, typically managed with glucocorticoids, with treatment varying on individual patient needs. While effective for GCA, long-term glucocorticoids use poses significant risks, including the development of osteoporosis, a metabolic bone disease common in older individuals. This overlap poses a significant clinical challenge, as the treatment for GCA inadvertently raises the risk of osteoporosis and necessitates careful balance to manage both conditions effectively.

Objectives: To investigate the occurrence of osteoporosis and other co-morbid conditions in patients with GCA treated with glucocorticoids.

Methods: A retrospective cross-sectional analysis of GCA patients examined the correlation between GCA and osteoporosis by searching the Clalit Health Service database for patients over 50 years of age from January 2002 to January 2018. In addition, we conducted a logistic regression analysis stratifying for other co-morbidities to evaluate the independent association between GCA and osteoporosis.

Results: In total, 6607 GCA patients were compared with 36,066 age- and sex-matched controls. The study revealed a higher prevalence of osteoporosis in the GCA group (43%) compared to controls (27%) (odds ratio [OR] 2.06, 95% confidence interval [95%CI] 1.95–2.17). In addition, hypertension, hyperlipidemia, diabetes mellitus, and ischemic heart disease were more prevalent among GCA patients. After stratifying for cardiovascular co-morbidities, GCA remained independently associated with osteoporosis (OR 2.1, 95%CI 1.96–2.26, P < 0.001).

Conclusions: Glucocorticoid-treated GCA is independently associated with osteoporosis. Healthcare providers must consider this added aspect of GCA for the treatment and management of patients.

Background: The prognostic significance of diabetes mellitus (DM) on hospitalization outcomes of patients with acute decompensated heart failure (ADHF) remains inconclusive.

Objectives: To comprehensively assess the clinical outcomes of patients with and without DM hospitalized for ADHF.

Methods: This single center retrospective cohort study included consecutive hospitalized patients with a principal diagnosis of ADHF between 1 January 2010 and 31 December 2019. Patients were categorized into diabetic and non-diabetic groups. The primary outcomes assessed were in-hospital mortality, 1-year overall mortality, and readmission rate within a year of follow-up.

Results: The final analysis involved 787 ADHF patients, with 62% having a pre-existing diagnosis of DM. Despite a higher burden of co-morbidities in diabetic patients, there were no differences in clinical outcomes when compared to non-diabetic counterparts. Specifically, there were no differences in overall hospital mortality (10% vs. 10%, P = 0.675), 1-year mortality (22% vs. 25%, P = 0.389), and re-admissions (51% vs. 56%, P = 0.154). Notably, the 1-year mortality among diabetic patients was not influenced by HbA1c levels documented before or during admission.

Conclusions: The clinical outcomes of patients hospitalized with ADHF did not differ by the presence of diabetes. Instead, our findings emphasize the importance of early heart failure prevention and subsequent hospitalization. Considering the evolving landscape of disease-modifying therapies for heart failure, achieving this goal becomes increasingly feasible.

Background: Acute skin infections, like cellulitis or erysipelas, are common and respond well to antibiotic treatment. However, complete resolution of the inflammatory process is often slow and associated with prolonged pain and reduced mobility. Several studies have indicated that acupuncture may effectively treat inflammatory skin diseases.

Objectives: To evaluate the efficacy of acupuncture for treating cellulitis in patients hospitalized in internal medicine departments.

Methods: In this pilot randomized sham-controlled trial, patients hospitalized with cellulitis in internal medicine departments were randomized to acupuncture or sham acupuncture, in addition to standard care. The primary outcome was the degree of improvement in the cellulitis score at day 4 of hospitalization. Secondary endpoints included patient pain self-assessment and local and systemic inflammatory signs.

Results: The study comprised 29 patients; 15 treated with acupuncture, 14 by a sham procedure. At day 4, patients in the acupuncture arm had an improved cellulitis score (4.1 ± 2.8) compared with the sham-control group (7.9 ± 3.3, P = 0.003). Pain intensity based on the Visual Assessment Scale was lower in the acupuncture group 3.8 ± 2.7 vs. 6.3 ± 2.8; P = 0.023. There was no difference in the rate of leukocyte change. However, C-reactive protein significantly decreased to 27.0 ± 22.1 mg/L at day 4 following acupuncture compared to 63.9 ± 51.9 mg/L (P = 0.025).

Conclusions: In our pilot study, we found acupuncture to be efficacious as an adjunctive therapy in the treatment of leg cellulitis. A large-scale trial on the effectiveness of acupuncture for skin infections is needed.

Myositis is described as any disease-causing inflammation in muscles. Muscle weakness is the most common symptom. Etiology includes infection, injury, medication side effects, and autoimmune conditions. The treatment varies according to the cause [1]. Statin induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare yet devastating complication of statin therapy that can occur at any time after initiation. The condition is also known as anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase antibody (anti-HMGCR antibody) myopathy. SINAM should be considered in patients who develop proximal muscle weakness and marked elevated creatine phosphokinase (CPK) while taking statin therapy [2]. We report on a patient who presented with excessive fatigue, generalized muscle pain, and weakness without dysphagia.

A 38-year-old immunocompetent male with a history of Hodgkin's lymphoma in remission presented to the emergency department at Rambam Hospital with infectious mononucleosis due to an acute cytomegalovirus (CMV) infection. He was also diagnosed with portal vein thrombosis (PVT). After a thorough laboratory and radiological investigation, these two diagnoses were found to be related. No other explanation was identified except for transiently detected antiphospholipid antibodies, which were assumed to be provoked by the CMV infection. In this review, we investigated the relationship between CMV infection and a hypercoagulable state. We searched the PubMed database for case reports, clinical reviews, and meta-analyses that reviewed the relationship between CMV infection and deep vein thrombosis. The incidence of thromboembolism in patients with acute CMV infection was reported to be as high as 6.4%. In addition, anti-cardiolipin antibodies were more commonly present at the time of PVT diagnosis among CMV-positive patients compared to CMV-negative patients, although these antibodies disappeared in most cases. To the best of our knowledge, there is no evidence of added benefit from antiviral therapy in patients with CMV-associated thrombosis. CMV infection may serve as a trigger for a transient hypercoagulable state.

Among the advancements in echocardiography, the introduction of two-dimensional strain marked a pivotal moment in the quantitative evaluation of cardiac function. In fact, Global longitudinal strain (GLS) has emerged as a key focus due to its robust validation and evidence base. GLS provides a comprehensive assessment of left ventricular function, which offers greater sensitivity in detecting subtle changes compared to traditional metrics such as ejection fraction. In this position paper, we elucidate the rationale behind routine global longitudinal strain calculation, offering practical recommendations and insights for its implementation in clinical echocardiography. By bridging technical nuances with clinical relevance, the calculation of longitudinal strain aims to optimize patient care and enhance the diagnostic precision of echocardiographic examinations.

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.

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.

Background: The coronavirus disease 2019 (COVID-19) pandemic showed the need to evaluate disease severity promptly at the time of hospital admission. 

Objectives: To establish an admission protocol, which included clinical and laboratory findings. 

Methods: We conducted a retrospective study at Wolfson Medical Center, Israel, for a period of 19 months (2020–2021). We established a protocol for patients who were admitted with COVID-19 infection. The protocol parameters included demographic data, co-morbidities, immune status, oxygen level at room air on admission, oxygen demand, lymphopenia, C-reactive protein (CRP) level, lactate dehydrogenase, D-DIMER, creatinine, aspartate transferase, alanine aminotransferase, and ferritin. Based on this protocol, we defined the severity of COVID-19 at the beginning of hospitalization and started treatment without delay. This protocol included ferritin levels as a guide to severity and outcome of patients. A database was established for all the parameters of the patients included in the study. 

Results: The study included 407 patients; 207 males (50.9%), 200 females (49.1%). The age range was 18–101 years. Hyperferritinemia (> 1000 ng/dl) was one of the strongest and most significant predictors for severe disease in these patients (P < 0.001). Lymphopenia, high levels of CRP, alanine aminotransferase, aspartate transferase, lactate dehydrogenase, and creatinine also correlated with severe disease, complications, and death. 

Conclusions: Abnormal ferritin levels were a very significant and clear indicator of the development of severe COVID-19. The addition of ferritin levels to our protocol aided in finding which patients were at increased risk for morbidity and mortality.
