Accurate mediastinal staging of lung cancer patients is critical for determining appropriate treatment. Mediastinoscopy and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration are the most commonly utilized techniques. Limited data exist on training and practice trends among thoracic surgeons. We aimed to determine training and practice patterns and find whether there is a paradigm shift in mediastinal staging after the introduction of EBUS into practice among thoracic surgeons in the United States.

The last two decades have witnessed a substantial increase in the incidence of bullous pemphigoid (BP) worldwide. One of the most compelling interpretations accounting for this epidemiological observation is the growing exposure to novel drug classes that might be implicated in eliciting the disease. Multiple lines of evidence have recently accumulated to suggest that exposure to dipeptidyl peptidase 4 (DPP4) inhibitors and checkpoint inhibitors (CPIs) is associated with an elevated risk of BP. As these drugs were introduced only in the past two decades, their rising utilization underlies, at least in part, the growing incidence of BP.

There is consensus that medical schools have a duty to educate students about social determinants of health (SDOH) and equip them with skills required to ameliorate health disparities. Although the National Academy of Medicine (NAM) urged the development of experiential long term programs, teaching is usually conducted in the pre-clinical years or as voluntary courses. ETGAR a required health disparities course, based on the social ecological model, was initiated to answer the NAM call. This study aimed to ascertain the course impact on students learning of SDOH and health disparities.

Hair thread tourniquet syndrome (HTS) is a pediatric condition in which human hair or synthetic fiber encircles and strangulates a body appendage causing tissue necrosis. Few epidemiologic studies have been done. Our objective was to better define the demographics, clinical features, and predisposing factors for this condition.

Janus kinase 2 (JAK2-V617F) mutations can cause thrombocytosis, polycythemia and hyper viscosity leading to cerebral sinus venous thrombosis (CSVT). However, data regarding the characteristics and prevalence of JAK2-V617F mutation in patients with CSVT are currently lacking. We aimed to evaluate the characteristics of CSVT patients that carry the JAK2 mutation.

This study aimed to examine the effects of a multi-day mountain bike race on amateur master athlete cyclists (AMA).

Corticosteroids, often known as steroids, are anti-inflammatory medicine prescribed for various conditions. There is accumulating evidence of immune dysregulation in major psychiatric disorders. Significant changes in concentrations of inflammatory biomarkers (i.e., IL-6 and TNF-a) have been previously reported in individuals with schizophrenia, autistic individuals, and depressive patients. Thus, systemic corticosteroids can be used as an adjuvant treatment to reduce inflammation in major psychiatric disorders. However, despite their well-known potent anti-inflammatory and immunosuppressant properties, this treatment is often associated with increased severity of several psychiatric symptoms and relapse. This article reviews the available literature on psychiatric and cognitive changes during corticosteroid therapy.

To the Editor: Recently, atenolol has generated interest as an alternative to propranolol in the treatment of Infantile hemangioma (IH), due to comparable efficacy and better safety profile, in terms of CNS-related adverse effects. Despite the promising benefits of atenolol treatment, its effects on CNS development in children have not been evaluated to date. Theoretically, atenolol, unlike propranolol which is lipophilic, has a hydrophilic structure that prevents it from crossing the blood-brain barrier (BBB). However, animal studies have shown that atenolol is actively effluxed into the brain and is able to induce central toxicity.  Therefore, the purpose of this study was to examine the effects of atenolol treatment on CNS development in infants with IH. 

Vici Syndrome is a rare, severe, neurodevelopmental/neurodegenerative disorder with multi-systemic manifestations presenting in infancy. It is mainly characterized by global developmental delay, seizures, agenesis of the corpus callosum, hair and skin hypopigmentation, bilateral cataract, and varying degrees of immunodeficiency, among other features. Vici Syndrome is caused by biallelic pathogenic variants in EPG5, resulting in impaired autophagy. Thus far, the condition has been reported in less than a hundred individuals. Objective and Methods: We aimed to characterize the clinical and molecular findings in individuals harboring biallelic EPG5 variants, recruited from four medical centers in Israel. Furthermore, we aimed to utilize a machine learning-based tool to assess facial features of Vici syndrome.

Both anaplastic thyroid carcinoma (ATC) and thyroid lymphoma (TL) clinically present as rapidly enlarging neck masses. Unfortunately, in this situation, like in any other thyroid swelling, a routine fine-needle aspiration (FNA) cytology is the first and only diagnostic test performed at the initial contact in the average thyroid practice. FNA, however, has a low sensitivity in diagnosing ATC and TL, and by the time the often "inconclusive" result is known, precious time has evolved, before going for core-needle biopsy (CNB) or incisional biopsy (IB) as the natural next diagnostic steps. Objectives: To determine the diagnostic value of CNB in the clinical setting of a rapidly enlarging thyroid mass, via a systematic review and meta-analysis of the available data on CNB reliability in the differential diagnosis of ATC and TL.

One main challenge in Helicobacter pylori (H. pylori) eradication is its increasing antibiotic resistance. Additionally, resistance rates vary between geographic areas and periods. However, data are limited since susceptibility testing is not routinely performed. Thus, it is valuable to gather data regarding H. pylori's resistance rates in Israel that would aid in better adjustment of treatment.The study included 540 H. pylori isolates, recovered from gastric biopsy samples of patients who had undergone endoscopy, during 2015-2020, at the Padeh Poriya Medical Center. 

Although oral anticoagulants (OACs) are first-line therapy for stroke prevention in patients with atrial fibrillation (AF), some patients cannot be treated with OACs due to absolute or relative contraindications. Left atrial appendage (LAA) exclusion techniques have been developed over the years as a therapeutic alternative for stroke prevention. In this paper, we review the evolution of surgical techniques, employed as an adjunct to cardiac surgery or as a stand-alone procedure, as well as the recently introduced and widely utilized percutaneous LAA occlusion techniques. 

The impact of social determinants on health status and outcomes has been widely established. However, it is recognized that health systems' ability to address community health needs may be limited. To better understand the interrelation between social determinants of health and health outcomes, health systems need to understand the health concerns and needs of populations. The aim of this study was to map the perceived health needs of Israel's northern periphery's diverse ethnic and religious communities and regional clusters by conducting a community health needs assessment (CHNA).

Vascular graft infection is a rare, life threatening complication of vascular repair with synthetic or native material. The pathogenesis, causative microorganisms and clinical manifestations vary according to graft's location and time duration since surgery. The diagnosis of graft infection is challenging since there is no single "gold standard" test and diagnosis is based on clinical and radiological criteria. 

While commonly thought to be effective for management of limb and junctional hemorrhage, the manual pressure points technique was excluded from leading prehospital guidelines over a decade ago following the publication of a single human-volunteers study presenting unfavorable results. This work aimed to re-assess the efficacy and feasibility of the femoral and supraclavicular pressure points technique for temporary hemorrhage control distal to the pressure point.
