The endocannabinoid system is involved in a host of homeostatic and physiologic functions, including modulation of pain and inflammation. The specific roles of currently identified endocannabinoids that act as ligands at endogenous cannabinoid receptors within the central nervous system (primarily but not exclusively CB1 receptors) and in the periphery (primarily but not exclusively CB2 receptors) are only partially elucidated, but they do exert an influence on nociception. Exogenous plant-based cannabinoids (phytocannabinoids) and chemically related compounds, like the terpenes, commonly found in many foods, have been found to exert significant analgesic effects in various chronic pain conditions. Currently, the use of Δ9-tetrahydrocannabinol is limited by its psychoactive effects and predominant delivery route (smoking), as well as regulatory or legal constraints. However, other phytocannabinoids in combination, especially cannabidiol and β-caryophyllene, delivered by the oral route appear to be promising candidates for the treatment of chronic pain due to their high safety and low adverse effects profiles. This review will provide the reader with the foundational basic and clinical science linking the endocannabinoid system and the phytocannabinoids with their potentially therapeutic role in the management of chronic pain.
In August of 2014, Manduca P et al. published “An open letter for the people in Gaza” in The Lancet. This letter was the response of those authors to their perspective of what was happening in Gaza during the summer-long conflict between Israel and Gaza. Israel was finally responding to years of bombardment from Gaza into civilian areas in the south of Israel. Two of the authors of the letters were known anti-Semites, and held connections with David Duke, a former Ku Klux Klan Grand Wizard in Louisiana and advocate of Nazism. Both these authors expressed sympathy and support for Duke’s rabidly anti-Jewish positions. In their letter they accused Israel’s medical community of complicity in committing terrible atrocities and even implied that chemical warfare was being used by Israel.
This paper is provided for the convenience of our readers and represents a full edited transcription of the Rambam Grand Rounds Lecture by Dr. Richard Horton, Editor-in-Chief of The Lancet. The lecture was given on October 2, 2014. The Editorial Board wishes to express its gratitude to Dr. Horton for giving permission to present his Rambam Grand Rounds lecture in Rambam Maimonides Medical Journal, in both the original video format and in this printed form.
Suicidal phenomena in the general hospital can take a variety of forms that can be parsed by taking into account whether or not the patient 1) intended to hasten death, and 2) included collaborators, including family and health care providers, in the decision to act. These two criteria can be used to distinguish entities as diverse as true suicide, non-compliance, euthanasia/physician-assisted suicide, and hospice/palliative care. Characterizing the nature of “suicide” events facilitates appropriate decision-making around management and disposition.
On May 28, 2014, colleagues from the Mayo Clinic visited Rambam Health Care Campus to gather and exchange ideas and knowledge. American and Israeli caregivers and scientists shared with each other the daily challenges of their practice in many and varied settings. This issue is dedicated to the presentations given and the collaborative efforts we are building as a result of that visit. We hope this issue will serve as an example of the fruitfulness of international collaboration to enhance and propagate medical knowledge worldwide.
Feelings of guilt have tormented Holocaust survivors, ranging from immediately after the liberation to later in life, for shorter or longer periods, and persisting for some throughout their entire post-war lives. Descriptions of the guilt experienced by survivors of the Nazi camps occupy an impressive amount of literature: “Why me?” was the question, when a younger and more able family member perished; “Why me?” when more productive members of the community perished; “Why me?” when a million and a half children were deprived of their lives. Many found the answer by retelling their stories, witnesses of what happened. This type of guilt is much different from the recently described phenomenon of survivor syndrome, namely the secondary guilt felt by Nazi-persecuted Jewish writers. Despite successes in all aspects of their life, these writers developed a self-incriminating guilt due to their perceived inadequacy of communicating, particularly in light of the resurging anti-Semitism worldwide. This paper deals with the survival and suicides of Nazi-persecuted Jewish writers and offers a possible explanation for their late self-destructive acts.
Medicine is developing through biomedical technology and innovations. The goal of any innovation in medicine is to improve patient care. Exponential growth in technology has led to the unprecedented growth of medical technology over the last 50 years. Clinician-scientists need to understand the complexity of the innovation process, from concept to product release, when working to bring new clinical solutions to the bedside. Hence, an overview of the innovation process is provided herein. The process involves an invention designed to solve an unmet need, followed by prototype design and optimization, animal studies, pilot and pivotal studies, and regulatory approval. The post-marketing strategy relative to funding, along with analysis of cost benefit, is a critical component for the adoption of new technologies. Examples of the road to innovation are provided, based on the experience with development of the transcatheter aortic valve. Finally, ideas are presented to contribute to the further development of this worldwide trend in innovation.
An anniversary is not only a point of memory—it provides the opportunity for self-examination and paves the way to the future. Every anniversary marks a starting-point that was preceded by a vision. The beginning of any vision is a personal dream—someone wants to improve or repair the world as far as he is able. The vision motivates action; in its aftermath comes the reality. This is the 21st issue of Rambam Maimonides Medical Journal. This issue is particularly important as it marks the completion of five years of creative work pursuing our vision for a high-caliber scientific medical journal. Our vision has become reality.
Background: Following the announcement of actress Angelina Jolie’s prophylactic bilateral mastectomies and subsequent prophylactic oophorectomy, there has been a dramatic increase in interest in BRCA testing and prophylactic surgery.
Objective: To review current medical literature on the benefits of prophylactic mastectomy and oophorectomy among BRCA-positive women and its permissibility under Jewish law.
Results: Recent literature suggests that in BRCA-positive women who undergo prophylactic oophorectomy the risk of dying of breast cancer is reduced by 90%, the risk of dying of ovarian cancer is reduced by 95%, and the risk of dying of any cause is reduced by 77%. The risk of breast cancer is further reduced by prophylactic mastectomy. Prophylactic oophorectomy and prophylactic mastectomy pose several challenges within Jewish law that call into question the permissibility of surgery, including mutilation of a healthy organ, termination of fertility, self-wounding, and castration. A growing number of Jewish legal scholars have found grounds to permit prophylactic surgery among BRCA carriers, with some even obligating prophylactic mastectomy and oophorectomy.
Conclusion: Current data suggest a significant reduction in mortality from prophylactic mastectomy and oophorectomy in BRCA carriers. While mutilation of healthy organs is intrinsically forbidden in Jewish law, the ability to preserve human life may contravene and even mandate prophylactic surgery.
Whilst painting the vault of the Sistine Chapel, Michelangelo Buonarroti left an autographical sketch that revealed a prominence at the front of his hyper-extended neck. This image was recently diagnosed as goiter. The poet Michelangelo in a sonnet dated 1509 described himself as being afflicted by goiter similarly to the cats in the northern Italian Lombardy, a region with endemic goiter. Several narratives extended this sonnet into a pathological theory. The analyses of Michelangelo’s works, however, his portraits and self-portraits, of poems and major biographies, have not indicated the likelihood of goiter. This investigation makes an attempt to assess the diagnosis on clinical as well as iconographical grounds.
