Bleeding tendency, a prominent feature of patients with Gaucher disease (GD), is associated with abnormal platelet function. Brain-derived neurotrophic factor (BDNF) is a protein with neuroprotective potential stored in alpha granules of circulating platelets. Here we studied BDNF levels in 50 patients with type I GD (GD1) and their correlation with platelet activity and bleeding tendency.

Musculoskeletal injuries dominate warfare-related trauma and differ from civilian settings in higher hospitalization costs, morbidity, and mortality. Partly due to introduction of personal protective equipment in the Israel Defence Force (IDF) to minimize head and torso injuries while the extremities remained unprotected. This study describes military extremity injury patterns, prehospital treatment and injury sequela regarding return-to-duty and disability compensation.

The Ultra-Orthodox Jewish population has behaviors that can influence the risk for osteoporotic fractures. We investigated whether this population is more prone to osteoporotic fractures than non-Orthodox Jewish. We did not find a significant difference in osteoporotic fracture rates between the two populations despite major differences in exposure to potential risk factors.

Endometriosis is a common, chronic, and inflammatory illness, with endometrioma a distinct advanced and progressive manifestation of the disease associated with reproductive dysfunction, infertility, and the need for ART treatment. Endometrioma is the most frequently diagnosed form of the disease, identified in up to 44% of affected women. However, the temporal management of endometriomas in women wishing to conceive or relative to ART treatment is not standardized, with surgery frequently advised pre-conceptually and before IVF treatment. Despite recent guidelines suggesting that clinicians may consider laparoscopy to treat infertility, routine endometrioma removal before ART is not indicated. Reevaluation of this practice within a critical framework that addresses the impact of endometrioma on ovarian reserve and whether its removal is beneficial in terms of fecundity and efficacy of ART treatment is, therefore, timely. This commentary explores recent evidence in a pragmatic question-driven approach and proposes a suggested clinical management strategy.

Post-paralytic facial synkinesis after facial nerve injury produces functional disabilities and mimetic deficits, but also cosmetic and non-motor psychosocial impairments for the patients. These patients typically have a high and continuous high motivation for rehabilitation. The aim is to inform the affected patients and their therapeutic professionals (otorhinolaryngologist - head and neck surgeons; oral-maxillofacial surgeons, plastic and reconstructive surgeons, neurosurgeons, neurologists, and mime therapists be it speech and language therapy- or physiotherapy-based) and to provide practical recommendations for diagnostics and a stepwise systematic treatment approach of facial synkinesis.

Statins have anti-inflammatory effects that are independent of their lipid-lowering activity. Objectives: To examine whether prior statins therapy affects the clinical course of the first episode of acute idiopathic pericarditis (AIP) as the 1-year recurrence and length of hospitalization (LOH).

An increased serum glucose level is a common finding among patients admitted to hospital with acute illness, including the intensive care unit (ICU), even without a history of previous diabetes mellitus (DM). Glycated hemoglobin (HbA1c) is not only a diagnostic tool for DM but may also has prognostic value for diabetic and non-diabetic populations.

To assess the relationship between HbA1c level on admission and clinical outcome among patients admitted to the ICU due to cardiopulmonary disorders with hyperglycemia.

Coronavirus disease 2019 (COVID-19) affects different people in different ways. Most infected people develop mild to moderate illness and recover without hospitalization. This case report presents a patient who had difficulty eradicating the corona virus due to being treated with rituximab, which depletes B lymphocytes and therefore disables the production of neutralizing antibodies.

Parkinson's disease (PD) is taking a staggering toll on healthcare systems worldwide, with the bulk of the expenditures invested in the late stages of the disease. Considering the rising life expectancy and the increasing prevalence of PD across the globe, a clear understanding of the early signs and treatment options available for advanced PD (APD), will facilitate tailoring management programs and support services. This task is complicated by the lack of both global consensus in defining APD and standardized care guidelines. This perspective prepared by a panel of movement disorder specialists, proposes to extend and optimize currently accepted PD coding to better reflect the diverse disease manifestations, with emphasis on non-motor features. 

Dissemination of cancer cells from the primary tumor into distant body tissues and organs is the leading cause of death in cancer patients. While most clinical strategies aim to reduce or impede the growth of the primary tumor, no treatment to eradicate metastatic cancer exists at present. Metastasis is mediated by feet-like cytoskeletal structures called invadopodia which allow cells to penetrate through the basement membrane and intravasate into blood vessels during their spread to distant tissues and organs. The non-receptor tyrosine kinase Pyk2 is highly expressed in breast cancer, where it mediates invadopodia formation and function via interaction with the actin-nucleation-promoting factor cortactin. Here, we designed a cell-permeable peptide inhibitor that contains the second proline-rich region (PRR2) sequence of Pyk2, which binds to the SH3 domain of cortactin and inhibits the interaction between Pyk2 and cortactin in invadopodia.

The incidence of blast injuries on the battlefield has risen over the last several decades. In order to improve prevention and treatment, it is essential to understand the severity and bodily distribution of these injuries. This study aims to characterize blast injury patterns among IDF fatalities.

In May 2021, the German parliament passed a long-debated law to protect children with variations of sex development/sex characteristics from medically unnecessary surgeries until they are old enough to decide for themselves. This law joins similar laws passed in other countries in recent years and recognizes the rights of people with variations of sex development to self-determination and bodily autonomy. In this article, we discuss the notion of bodily autonomy and examine details of the German legislation in the context of psychosocial care. We focus on the following questions: (1) How may the law help to preserve the genital integrity and future bodily autonomy of newborns with variations of sex development (VSD)? (2) What are the opportunities and challenges of this law? (3) What strategies are needed to implement the law in ways that include medical professionals' knowledge and skills, parental cooperation, and protection for the genital integrity as well as the future genital autonomy of newborns with VSD?

Patients who are admitted with acute cholecystitis (AC) and do not undergo urgent cholecystectomy, are usually referred for interval cholecystectomy. Many do not have surgery for various reasons, and some of those do not suffer from any recurrent symptoms. The primary objective of this study was to assess the rate and nature of recurrent gallstone-related events in this population over a long period, and its association with demographic and clinical parameters. A secondary objective was to assess the reasons for not undergoing surgery.

Birth weight is considered not only to undermine future growth, but also to induce lifelong diseases; the aim of this study is to explore the relationship between birth weight and adult bone mass.

During the past 74 years since its establishment, Israel has evolved into a modernized country with well-established and effective public health care system. Thoracic surgeons in Israel play a central role in the diagnosis and treatment of patients with diseases of the chest wall, diaphragm, mediastinum, airways, Lung, and esophagus as well are taking part in designated trauma teams....
