The twentieth century witnessed profound changes in medical education. All these changes, however, took place within the existing framework, suggested by Flexner a century ago. The present paper suggests that we are approaching a singularity point, where we shall have to change the paradigm and be prepared for an entirely new genre of medical education. This suggestion is based upon analysis of existing and envisaged trends: first, in technology, such as availability of information and sophisticated simulations; second, in medical practice, such as far-reaching interventions in life and death that create an array of new moral dilemmas, as well as a change in patient mix in hospitals and a growing need of team work; third, in the societal attitude toward higher education. The structure of the future medical school is delineated in a rough sketch, and so are the roles of the future medical teacher. It is concluded that we are presently not prepared for the approaching changes, neither from practical nor from attitudinal points of view, and that it is now high time for both awareness of and preparation for these changes.
It has been argued that human evolution has stopped because humans now adapt to their environment via cultural evolution and not biological evolution. However, all organisms adapt to their environment, and humans are no exception. Culture defines much of the human environment, so cultural evolution has actually led to adaptive evolution in humans. Examples are given to illustrate the rapid pace of adaptive evolution in response to cultural innovations. These adaptive responses have important impli-cations for infectious diseases, Mendelian genetic diseases, and systemic diseases in current human populations. Moreover, evolution proceeds by mechanisms other than natural selection. The recent growth in human population size has greatly increased the reservoir of mutational variants in the hu-man gene pool, thereby enhancing the potential for human evolution. The increase in human popula-tion size coupled with our increased capacity to move across the globe has induced a rapid and ongoing evolutionary shift in how genetic variation is distributed within and among local human populations. In particular, genetic differences between human populations are rapidly diminishing and individual het-erozygosity is increasing, with beneficial health effects. Finally, even when cultural evolution eliminates selection on a trait, the trait can still evolve due to natural selection on other traits. Our traits are not isolated, independent units, but rather are integrated into a functional whole, so selection on one trait can cause evolution to occur on another trait, sometimes with mildly maladaptive consequences.
All possible pro and con arguments regarding the theory of evolution have been discussed and debated in the vast literature—scientific, religious, and lay—in the past 150 years. There is usually great zealotry in all debating parties, with mutual intolerance of ideas and concepts, disrespect toward opposing opi-nions and positions, and usage of very harsh language. This prejudiced approach usually does not allow for a reasonable debate. It is important to look at the facts, assumptions, and beliefs of the theory of evolution in a more calm and humble way.In this article a comparative analysis is offered between the scientific aspects of the theory of evolution and a Judaic approach to these aspects.The two sets of human thought—religion and science—are fundamentally different in their aims and purposes, in their methods of operation, in their scope of interest and issues, and in their origin and ramifications. Whenever science surpasses its limits, or religion exceeds its boundaries, it actually is a form of an abuse of both. This has happened to the theory of evolution in a more powerful mode than any other interaction between science and religion.The agenda of many scientists who promote the theory of evolution is to achieve the goal of under-standing the existence of the universe as a random, purposeless, natural development, evolved slowly over billions of years from a common ancestor by way of natural selection, devoid of any supernatural metaphysical power.Jewish faith perceives the development of the universe in a different way: God created the world, with a purpose known to Him; He established natural laws that govern the world; and He imposed a moral-religious set of requirements upon Man.The discussion and comparative analysis in this article is based upon the current neo-Darwinian theory, although it seems almost certain that even the new and modern assumptions and speculations will continue to be challenged, changed, and revised as new scientific information will be discovered.The theory of evolution is based upon certain facts, many assumptions, speculations, and interpreta-tions, and some fundamental non-evidence-based beliefs.
Complex disorders are common in the human population and are caused by interplay between genetic and environmental factors. Therefore the quest for the genetic basis of such disorders has much similar-ity to deciphering the genetic basis of macro-evolutionary processes, such as speciation. Here I discuss conceptual connections between the principles underlying and processes occurring in disease and evo-lution. Special focus is given to the tremendous mitochondrial genetic variability in the population and within individuals and the impact of both types of variability on evolutionary processes and diseases.
Moses Maimonides, the illustrious medieval rabbi and philosopher, dedicated the last decade of his life primarily to medicine. His strong interest in medicine was an integral component of his religious-philosophical teachings and world view. In this paper various sources from his rabbinic writings are presented that explain Maimonides’ motivation regarding and deep appreciation for medicine: (A) The physician fulfills the basic biblical obligation to return lost objects to their owner, for with his knowledge and experience the physician can restore good health to his sick fellow human being; (B) medicine provides a unique opportunity to practice imitatio dei, as it reflects the religious duty to maintain a healthy life-style; (C) as an important natural science, medicine offers tools to recognize, love and fear God. These three aspects address man’s relationship and obligation towards his fellow man, himself and God. Biographical insights supported by additional sources from Maimonides’ writings are discussed.
After direct impact of the trauma, crush syndrome is the second most frequent cause of death after mass disasters. However, since crush syndrome is quite rare in daily practice, mistakes are frequent in the treatment of these cases. This paper summarizes the etiopathogenesis of traumatic rhabdomyolysis and of crush syndrome-based acute kidney injury. The clinical and laboratory features, prophylaxis, and treatment of crush cases are summarized as well. The importance of early and energetic fluid resuscitation is underlined for prophylaxis of acute kidney injury. Since there is chaos, and an overwhelming number of victims, logistic drawbacks create a specific problem in the treatment of crush victims after mass disasters. Potential solutions for logistic hurdles and disaster preparedness scenarios have also been provided in this review article.
In this brief review, written from the perspective of a physician-leader who has fostered the development of comprehensive quality improvement efforts at two academic medical centers, I review the need for improvement, some conceptual barriers that must be overcome, the goals of a comprehensive quality improvement (QI) effort, some of the results we have obtained, and some observations on how to develop a culture of continuous improvement in an academic medical center. The mandate for quality improvement is clear; current healthcare is wasteful and error-prone, leading to excessive morbidity and mortality and unsustainably high costs. Successful quality improvement requires the abandonment of two paradigms: the craft model of medical practice and the notion that many forms of harm to patients are not preventable. I will describe how dramatic improvement has been achieved in reducing, by up to 10-fold, rates of central line infections, ventilator-associated pneumonias, peritonitis in peritoneal dialysis patients, and mortality due to cardiac arrest in hospital. I will describe as well how these methods can improve access to out-patient clinics dramatically and enhance the reliability and safety of hand-offs between covering physicians. To develop and maintain systematic quality improvement in all phases of medical care we must articulate a culture in which: everyone working at the medical center makes improvements every day; front-line staff, who know best how the work is done, are empowered to improve the processes of care; and multidisciplinary teams create the protocols that reduce variation that is due to physician preference, leaving only the variation required by the individual needs of patients. I will review as well the crucial elements of education of trainees and faculty members needed to guide and sustain a culture of quality. Finally, I will add some observations on how oversight boards and medical center leaders can help create systematic quality improvement in their medical centers.
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.
Advancements in computers, prototyping, and imaging, especially over the last 10 years, have permitted the adoption of three-dimensional imaging protocols in the health care field. In this article, the authors present an integrated simulation system for craniofacial surgical planning and treatment. Image fusion technology, which involves combining different imaging modalities, was utilized to create a realistic prototype and virtual image that can be manipulated in real time. The resultant data can then be shared over the Internet with distantly located practitioners.
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.
