Although Maimonides stated that perfection in the medical art, both in theoretical and in practical expertise, is very difficult to achieve, he did not accept Galen's opinion, i.e. that perfection is beyond human capability.
Any person seeking intellectual perfection should, according to Maimonides' view, be fully trained in logic, in the natural sciences, and in theology.
A physician is moreover requested to study and memorize basic medical literature; he must consider each patient as a sick individual, without neglecting the patient's psychological disposition; and he should aim at inspiring confidence and trust, not only to his patient, but also to the latter's environment.
Even when feeling competent and trustworthy, the physician should not be conceited; here Maimonides insists on offering his personal experience, in a quite impressive way.
This approach of Maimonides to the practice of medicine should be considered, even today, as a valuable incentive for patient-oriented medical education, as already expressed in the late eleventh century.
Celiac disease (CD) is an autoimmune disorder occurring in genetically susceptible subjects. The incidence of CD is around 1%, and it is much more common in first-degree relatives of CD patients, 10%–18%. However, the pattern of the genetic inheritance is still obscure. Environmental factors are undoubtedly affecting the disease’s clinical presentation, time at presentation, and maybe effect on the characteristics of the disease. The clinical presentation of CD has shifted during the previous decades from the classical presentation in which the toddler suffers from diarrhea, constipation, vomiting, failure to thrive, abdominal distension, etc., to the child with a monosymptomatic presentation, such as anemia, as well as an enlarged list of extra-intestinal disorders. The diagnosis of CD is being established by symptoms consistent with CD and positive serology. The ultimate diagnosis should be made upon histological evaluation of the small bowel mucosa. The treatment of CD is a lifelong, strict gluten-free diet (GFD). Compliance with a GFD is quite difficult. Therefore, new strategies for prevention and treatment modalities other than GFD are greatly needed. Recently several promising therapeutic modalities have been developed; these include resuming traditional baking techniques. Another methodology is using probiotic-driven prolylendopeptidase. Another pathway to tackle the therapeutic option in CD is by down-regulation of the activity of zonulin—the active pump enabling gluten to enter the enterocytes. We are facing an era where other modalities beyond a GFD might allow CD patients to be able to tolerate occasionally a small amount of gluten in their diet.
Background—Bedside rounds have long been a time-honored component of medical education. Recently, there have been various recommendations that residency training programs further incorporate bedside teaching into clinical curricula.
Objectives—To compare these current attitudes regarding bedside education with the position of traditional Jewish law and ethics.
Methods—Relevant medical journal articles and traditional Jewish sources were reviewed.
Results—Halakha (the corpus of traditional Jewish law and ethics) gives greater focus to a patient-centered rather than student-centered bedside education experience.
Conclusion—Residency training programs should give greater consideration to the importance of a patient-centered bedside education experience.
Lipman Halpern was born in 1902 into a family of Grand Rabbis who lived in Bialystok from the mid-nineteenth century. Inspired by his son’s decision to study medicine, Halpern’s father authored a comprehensive and innovative book on medicine according to Rabbinic Law. After completing his initial medical studies in Königsberg, Halpern went on to specialize in neuropsychiatry in Berlin and then in Zurich.
In 1934, Halpern immigrated to Eretz-Israel (then Palestine), where he founded and expanded the Department of Neurology at the Hadassah University Hospital in Jerusalem. Under his guidance, the department became a leader in clinical neurology, clinical and basic neurological research, and teaching. For the graduation of the first class of the Faculty of Medicine of the Hebrew University of Jerusalem in 1952, he authored the “Oath of the Hebrew Physician,”which went on to become the official oath for all new physicians graduating from Israeli faculties of medicine.
Halpern authored many clinical and research articles in English, German, French, and Hebrew. His studies on the relationship between the vestibular, cerebellar, and visual systems resulted in the description of the phenomenon of “monocular disequilibrium”and the “sensory motor induction syndrome,”also known as “Halpern’s syndrome.”In 1953 he became the first Israel Prize laureate in Medicine. Halpern died in 1968 while serving his second term as Dean of the Faculty of Medicine at Hebrew University.
Bone structural integrity and shape are maintained by removal of old matrix by osteoclasts and in-situ synthesis of new bone by osteoblasts. These cells comprise the basic multicellular unit (BMU). Bone mass maintenance is determined by the net anabolic activity of the BMU, when the matrix elaboration of the osteoblasts equals or exceeds the bone resorption by the osteoclasts. The normal function of the BMU causes a continuous remodeling process of the bone, with deposition of bony matrix (osteoid) along the vectors of the generated force by gravity and attached muscle activity. The osteoblasts are derived from mesenchymal stem cells (MSCs). Circulating hormones and locally produced cytokines and growth factors modulate the replication and differentiation of osteoclast and osteoblast progenitors. The appropriate number of the osteoblasts in the BMU is determined by the differentiation of the precursor bone-marrow stem cells into mature osteoblasts, their proliferation with subsequent maturation into metabolically active osteocytes, and osteoblast degradation by apoptosis. Thus, the two crucial points to target when planning to control the osteoblast population are the processes of cell proliferation and apoptosis, which are regulated by cellular hedgehog and Wnt pathways that involve humoral and mechanical stimulations. Osteoblasts regulate both bone matrix synthesis and mineralization directly by their own synthetic activities, and bone resorption indirectly by its paracrinic effects on osteoclasts. The overall synthetic and regulatory activities of osteoblasts govern bone tissue integrity and shape.
The term sarcopenia describes the loss of skeletal muscle mass, strength, and function in old age. As the world population continues to grow older, more attention is given to the phenomena of sarcopenia and the search for strategies of prevention and treatment. The progression of sarcopenia is affected by age-related physiological and systemic changes in the body, including alterations in skeletal muscle tissue, hormonal changes, increased inflammatory activities, and oxidative stress. Sarcopenia progression is also affected by lifestyle factors which are far more controllable. These factors include various aspects of nutrition, physical activity, exercise, alcohol intake, and tobacco use. Raising the public awareness regarding the impact of these factors, as causes of sarcopenia and potential strategies of prevention and treatment, is of great importance. In this review we aim to describe various lifestyle factors that affect the etiology, prevention, and treatment of sarcopenia.
The sirtuins are highly conserved enzyme homologues of the yeast Sir2, with activities of NAD+ dependent deacetylase and/or mono ADP ribosyltransferase. A long line of evidence has implicated sirtuins in regulating the aging process of yeast, worms, flies, and rodents. Moreover, much work has been published on the important role of sirtuins in several age-related diseases such as diabetes type II, cancer, cardio¬vascular diseases, and dyslipidemia. However, despite the many publications supporting a pro-longevity role for sirtuins, there has been emerging debate about the direct role of Caenorhabditis elegans and Drosophila melanogaster sirtuins in aging and in lifespan extension in response to dietary restriction. In addition, until recently, the role of the seven mammalian sirtuins, SIRT1 to SIRT7, in regulating lifespan was unclear. Here, we review the history of the scientific debate on the role of sirtuins in regulating lifespan, especially in light of a recent publication showing a direct regulation of mammalian lifespan by a sirtuin family member, SIRT6.
Successful deceased organ donation requires a reproducible—consistent (scientific) system that eva-luates the potential for organ donation and determines objectively whether the national system is achieving its goals. The science of organ donation also pertains to the determination of death. We are a common humanity that dies similarly— a humanity whose ultimate criterion of life resides in the function of the human brain. The recent brain death law of Israel encouragingly enables a determination of death by the loss of neurologic function but it has become complicated by a practice that may perpetuate societal misperceptions. As a result opportunities for deceased organ donation --to provide for Israelis in need of organ transplants are being lost. A statured task force of society could be assembled to convey its support for deceased donation to influence society and resolve these misperceptions.
The World Health Organization is now calling for each member state to achieve a self-sufficiency in organ donation and transplantation "equitably meeting the transplantation needs of a given population using resources from within that population". Patients should not be compelled to go to foreign countries for their organs. Israel has been a leader in the development of a model program intended to address transplant tourism. Insurance companies are no longer permitted to provide resources for Israelis to undergo illegal transplants in foreign destinations. The social necessity of a scientifically and medically applied system of deceased organ donation is now evident so that a sufficient number of organs can be available for patients from within the country they reside.
This manuscript is a survey of the halachic attitudes toward organ transplant procedures from a living donor which can be defined as life-saving procedures for the recipient or at least life-prolonging proce-dures. Three fundamental problems concerning the halachic aspects of such transplantation are dis-cussed in detail: the danger to the donor, donation under coercion, and the sale of organs and tissues. The terms “halacha” and “Jewish law” are defined in the introduction.
This paper examines the morality of schemes of payment to live donors/sellers of organs for transplantation. Following empirical and historical evidence it is argued that consent to sell organs is substantially different from consent to ordinary business transactions and that legalization of exchanges of organs with financial benefits deviates significantly from the scope of liberal toleration and human rights. Although altruistic giving is commendable, it is immoral for society to benefit from them without conferring to the donors benefits such as health and nursing insurance for life. Non-alienable and non-fungible benefits of this kind are moral as incentives to organ donation/giving
