Because of its high case-fatality rate, its very high transmission potential, and the worldwide shortage of effective vaccine, smallpox tops international lists of over a dozen possible bioterror and biologic warfare agents. In a scenario involving aerosol variola virus release, tens to hundreds of first-generation cases would ensue, as would hundreds to thousands of subsequent cases resulting from person-to-person transmission. A smallpox outbreak in Israel must not be regarded as a doomsday event: the methods of smallpox outbreak control are known and will be implemented. The rapidity with which organized outbreak control measures are competently executed will determine how many generations of cases occur before the outbreak is brought under control. Planning, vaccine stockpiling, laboratory expansion, professional training and public education, all carried out well in advance of an epidemic, will minimize the number of casualties. The reinstitution of routine smallpox vaccination in Israel, as in other countries, must be given serious consideration, since it has the potential for eliminating the threat of smallpox as a bioterror agent.

Recent events have significantly increased concern about the use of biologic and chemical weapons by terrorists and other countries. Since weapons of mass destruction could result in a huge number of casualties, optimizing our diagnostic and therapeutic skills may help to minimize the morbidity and mortality. The national demands for training in medical aspects of nuclear, biologic and chemical warfare have increased dramatically. While Israeli medical preparedness for non-conventional warfare has improved substantially in recent years especially due to extensive training programs, a standardized course and course materials were not available until recently. We have developed a core curriculum and teaching materials for a 1 or 2 day modular course, including printed materials.

Intractable forms of autoimmune diseases follow a rapid course, with a significantly shortened life expectancy sometimes comparable to that of malignant diseases. Immunoablative therapy, including high dose cytotoxic agents and hematopoietic autologous stem cell rescue, was recently introduced as an aggressive approach to treat autoimmune diseases that have a rapid course and are resistant to conventional therapy. The most frequent indication for this type of treatment is multiple sclerosis, seconded by systemic sclerosis. The results of immunoablative treatment with documented responses in both diseases are encouraging. The data are mature enough to begin comparative randomized studies of immunoablative versus conventional treatment to validate the benefit of the aggressive approach. A randomized trial involving SSc[1] was recently launched (ASTIS) and a trial involving MS[2] is under preparation. Considerably less experience with immunoablative treatment has been gained in systemic lupus erythematosus, rheumatoid arthritis, and other disorders with an autoimmune pathophysiology. Autologous hematopoietic stem cell transplantation in humans offers more long-lasting immunosuppression than reeducation of lymphocytes. In fact, allogeneic transplantation may replace the whole immune system. However, this attractive approach is still associated with considerable morbidity and mortality and is not yet justified for treatment of automimmune diseases. Non-myeloablative allogeneic transplantation and sub-myeloblative high dose cyclophosphamide without stem cell support are alternative approaches that could be explored in pilot studies.

Henri Bergson (1859-1941) was probably the most influential French philosopher at the turn of the twentieth century. In 1927 he was awarded the Nobel Prize for literature. Far beyond the restricted academic philosophical milieu, the impact of his thinking reached personalities as diverse as Claude Debussy, Marcel Proust, George Bernard Shaw, and the impressionists.  His essay The Laughter (Le Rire) is one of the most profound and original ever written on the sense of humor. Bergson’s opinions, with their emphasis on life, instinct and intuition, represented a deviation from the rationalist mainstream of western philosophical tradition. In some circles he was received with skepticism and irony as in Bertrand Russel’s History of Western Philosophy. Today, unbiased by theoretical "bergsonism," neurophysiologic research - as undertaken mainly by Antonio Damasio’s team at Iowa University - confirms many of his hypotheses and elucidates their mechanisms. In this new light, intuition and “recognition by the body” should not be seen as the personal fantasy of an original thinker but as fundamental cognitive tools.

Background: Previous studies have demonstrated myocardial salvage by basic fibroblast growth factor administration following chronic myocardial ischemia or acute myocardial infarction.

Objectives: To study the effect of bFGF[1] on left ventricular morphometry following coronary occlusion and reperfusion episode in rats.

Methods: bFGF (0.5 mg) or placebo was continuously administered for a period of one week using an implanted osmotic pump. Animals were sacrificed 6 weeks after surgery and myocardial cross-sections were stained with Masson-trichrome and with anti-proliferating cell nuclear antigen antibody.

Results: LV[2] area, LV cavity diameter, LV cavity/wall thickness ratio, and injury size were unchanged compared with control animals. Proliferating endothelial cells were significantly more abundant in injured compared with normal myocardium, but with no differences between animals treated or not treated with bFGF.

Conclusions: One week of systemic bFGF administration following coronary occlusion and reperfusion had no additional effect on LV geometry or cellular proliferation in rats.

Background: Which medical specialties do Israeli medical graduates choose? Answers to this question can serve as an essential means of evaluating both Israeli medical education and the healthcare system.

Objectives: To determine the distribution of medical specialty choice, its change over time and the posible influence of the medical school on the choice; to study the graduates’ gender, gender variability in specialty choice of family medicine as a career among the graduates as a group, by medical school, gender, and time trends.

Method: The study population comprised all graduates of the four medical schools in Israel during 16 years: 1980-1995 inclusive. Data were obtained from the four medical schools, the Israel Medical Association’s Scientific Council, and the Ministry of Health. Data allowed for correct identification of two-third of the graduates.

Results: A total of 4,578 physicians graduated during this period. There was a significant growth trend in the proportion of women graduates from 22.6% in 1980 (lowest: 20.0% un 1981) to 35.3 in 1995 (highest: 41.5% in 1991). Overall, 3,063 physicians (66.8%) started residency and 1,714 (37.4%) became specialists. The four most popular residencies were internal medicine. Ten percent of Israeli graduates choose family medicine.

Conclusions: The overall class size in Israel was stable at a time considerable population change. Women’s place in Israeli medicine is undergoing significant change. Family medicine is one of the four most popular residencies. Amonitoring system for MSC in Israel is imperative.
 

Background: Familial Mediterranean fever is a genetic disease in which some characteristic gene mutation have been found.

Objective: To analyze the phenotype-genotype correlations in North African Jews and Armedians with FMF.

Methods: We studied MEFV gene mutations and phenotype-genotype correlations in North African Jews and Armedians with Familial Mediterranean Fever living in France.

Results: M694V mutation was the most common mutation in Jews and in Armenians. Patients with M6801 homozygosity or M6801/M694V compound heterozygosity had a phenotype as severe as patients with M694V homozygosity.

Conclusions: This study characterizes the phenotype-genotype in specific ethnic groups of patients with FMF.

Background: Musculoskeletal complaints represent the second most common reason for visits to a physician, second only to the common cold. The limited capability of medical treatment for musculoskeletal disease requires modification of communication with patients by attending to their perception of the disease.

Objectives: To assess patients’ satisfaction with care provided by their primary physicians, and the relationship of patients' satisfaction to their expectations of that care, perceptions of physician performance, and perceived severity of musculoskeletal disease.

Methods: Questionnaires were administered to 90 community-dwelling elderly patients (mean age 76+-8 years) presenting for follow-up appointments with their primary care physicians. Patients were asked to report on their satisfaction with the medical care provided by the primary physicians for musculoskeletal symptoms, their expectations of that care, their perceptions of their primary physicians' interaction (regarding competence, performance, and communication), and their perceptions of disease severity (based on the number of areas involved, pain frequency and intensity, and impact on daily activity). The effects on the degree of satisfaction were assessed with regard to demographic variables, co-morbidity, site involved, and response to recommended treatment.

Results: Most patients (> 85%) expressed overall satisfaction with their doctor's interpersonal skills. Fewer (76.9%) were satisfied with the amount of effort their doctors spend evaluating their musculoskeletal symptoms, the information received regarding their musculoskeletal symptoms (75%), the degree of pain relief (75%), and the degree of functional improvement (61.8%). Level of education and response to recommended treatment for musculoskeletal disease were the only parameters associated with degree of satisfaction (higher education P = 0.005, lower education P = 0.059, medication P = 0.008, rehabilitation P = 0.076). A high level of expectations (regarding physician's care and musculoskeletal disease treatment) was noted.

Conclusions: The high level of patient satisfaction with their primary physicians' care for musculoskeletal symptoms may reflect the overall tendency of the elderly population to be satisfied with its primary care physicians. However, their high level of expectations (related to perceived efficacy of medical treatment) and their unrealistic perceptions of disease may lead to disappointment and non-compliance with their doctor's recommendations. Management of musculoskeletal disease in the elderly should address the patients’ disease perceptions, as well as their therapeutic and functional needs.
 

Background: Leiomyoma is the common benign tumor of the female genital tract. The traditional treatment is hysterectomy, myomectomy or medical therapy by hormonal manipulation. Uterine arterial embolization, a recognized treatment for acute pelvic hemorrhage, has recently been applied to the management of non-acute uterine hemorrhage due to leiomyoma.

Objective: To describe our experience with uterine arterial embolization for the management of uterine fibroid.

Methods: Uterine arterial embolization was performed in nine patients with leiomyomas in whom medical therapy failed and who sought to avoid surgery.

Results: Follow-up ultrasound examination after 2 months revealed an average reduction in fibroid volume of 38%. There were no early or long-term complications.

Cunclusions: Uterine arterial embolization appears to be effective and safe in the management of symptomatic leiomyomas. It is a promising alternative to myomectomy or hysterectomy and warrants further investigation in this setting.
 

Background: The impact of repeated surgical resection on the survivorship of patients with malignant astrocytomas is an issue of some controversy in the medical literature.

Objectives: To clarify this issue through a retrospective analysis of treatment outcomes in a brain tumor clinic.

Methods: The patient records from the Brain Tumor Clinic at Hahnemann University Hospital for the period 1988 to 2000 were reviewed. From these, 112 cases of glioblastoma multiforme and 50 cases of anaplastic astrocytoma were chosen for analysis.

Results: The group of patients with glioblastomas showed a median survival of 415 days. When analyzed as subgroups based on the number of surgical resections, the median survival was 393 days in the group with biopsy only, 380 days in the group with one surgical resection, and 548 days in the group with two or three resections. Using the Kaplan-Meier method to generate survival plots and the log rank test to compare groups, repeat debulking was found to be a significant predictor of survival (P= 0.1 73). The group of patients with anaplastic astrocytomas showed a median survival of 1,311 days. When analyzed by subgroups, the patients with biopsy only had a median survival of 544 days, those with one debulking 1,589 days and those with two or three debulkings 1,421 days. There was a trend toward increased survival with debulking and the log rank test again showed statistical significance (P 0.1998).

Conclusions: This study indicates that repeated surgical resections offer increased survival for both glioblastomas and anaplastic astrocytomas.
