End-of-life decisions are made daily in intensive care units worldwide. There are numerous factors affecting these decisions, including geographical location as well as religion and attitudes of caregivers, patients, and families. There is a spectrum of end-of-life care options from full continued care, withholding treatment, withdrawing treatment, and active life-ending procedures.
Background. Spermatocytic seminoma is a rare testicular malignancy, appearing in the adult population. It has a good prognosis and a low rate of metastatic potential.
Objectives. We present five cases diagnosed and treated with radiotherapy at Rambam Health Care Campus in Haifa, Israel.
Methods. Between 1974 and 1996, five patients with stage I spermatocytic seminoma were referred post-orchiectomy to the Northern Israel Oncology Center. All five patients presented with the typical pathological features of the spermatocytic variant of classic seminoma, and all were staged clinically and radiologically.
Results. Mean age at diagnosis was 44 years (range 30–58 years). Main symptoms included a palpable testicular mass and/or testicular enlargement. Mean duration of symptoms was 9 months (range 0.5–24 months). Three patients were irradiated to the para-aortic/ipsilateral iliacal lymph nodes (mean total dose 2,500 cGy), one patient with 4,000 cGy. One patient was irradiated to the bilateral iliacal lymph nodes (2,600 cGy). With a median follow-up of 15 years, four patients are alive with no evidence of disease or severe late side effects. One patient developed severe lymphedema and symptomatic peripheral vascular disease, stage IIA prostate carcinoma (hormonal and brachytherapy treatment) and a non-secretory hypophyseal adenoma (surgically removed); he died at the age of 75 due to severe peripheral vascular and coronary heart disease with no evidence of his first or second primaries.
Conclusions. Prognosis is excellent and does not differ from classic seminoma. As in the accumulated experience in early-stage, low-risk classic seminoma, we suggest surveillance as the preferred policy.
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.
Purpose. This is a population study of patients who were treated for vulvar cancer in a tertiary center in northern Israel, aimed to report clinical findings, treatment, and outcome.
Methods. A retrospective chart review of all medical records of consecutive patients who were treated for vulvar cancer in the years 1993–2012 was conducted. Data extracted from the medical records included demographics, histology, size of lesion, stage of disease at diagnosis, type of treatment, radiation dose, follow-up, recurrence, and survival.
Results. The study included 44 patients with a median age of 69.8 years (range, 42–93 years). Thirty-five (79.5%) of the patients were of Jewish descent, five were Arabic, and four were of other descent. The most common histology type was squamous cell carcinoma in 35 (79.5%) patients. Most patients were staged FIGO II–III at time of diagnosis. Surgery was the most common primary treatment modality (54.2%). Twenty-three (52.2%) patients had recurrent disease. Older age and more advanced stage at diagnosis were associated with increased mortality.
Conclusion. Vulvar cancer is common among elderly women with co-morbidities who present in advanced disease stage; all these factors are significant for survival.
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.
Intelligent Design (ID) burst onto the scene in 1996, with the publication of Darwin’s Black Box by Mi-chael Behe. Since then, there has been a plethora of articles written about ID, both pro and con. How-ever, most of the articles critical of ID deal with peripheral issues, such as whether ID is just another form of creationism or whether ID qualifies as science or whether ID should be taught in public schools. It is our view that the central issue is whether the basic claim of ID is correct. Our goal is fourfold: (I) to show that most of the proposed refutations of ID are unconvincing and/or incorrect, (II) to describe the single fundamental error of ID, (III) to discuss the historic tradition surrounding the ID controversy, showing that ID is an example of a “god-of-the-gaps” argument, and (IV) to place the ID controversy in the larger context of proposed proofs for the existence of God, with the emphasis on Jewish tradition.
This paper describes the rapid evolution of modern liver surgery, starting in the middle of the twentieth century. Claude Couinaud studied and described the segmental anatomy of the liver, Thomas Starzl performed the first liver transplantations, and Henri Bismuth introduced the concept of anatomical resections. Hepatic surgery has developed significantly since those early days. To date, innovative techniques are applied, using cutting-edge technologies: Intraoperative ultrasound, techniques of vascular exclusion of the liver, new devices for performing homeostasis and dissection, laparoscopy for resections, and new drugs that allow the resection of previously unresectable tumors. The next stage in liver surgery will probably be the implementation of a multidisciplinary holistic approach to the liver-diseased patient that will ensure the best and most efficient treatments in the future.
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.
Patients with type 2 diabetes (T2D) are at increased risk of developing cancer. This evidence arises from numerous epidemiologic studies that relate a positive association between T2D and cancer. In-vitro and several in-vivo experiments have attempted to discern the potential mechanistic factors involved in this relationship. Candidates include hyperinsulinemia, insulin-like growth factor-1 (IGF-1), and insulin-like growth factor-2 (IGF-2) signaling. These studies demonstrated that increased insulin, IGF-1, and IGF-2 signaling through the insulin receptor and IGF-1 receptor can induce cancer development and progression.
The paper proposes moral and ethical guidelines for medical treatment at the edge of viability. The proposed principles are defended on the grounds of a general conceptual framework presented by elucidating the notions of viability, the edge of viability, person, sanctity of human life, dignity, and the slope of dignity protection, as well as the distinction between ethics and morality.
