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: Most of the published documents proposing teaching objectives for undergraduate clerkships were prepared by expert bodies. Seldom have the clinical teachers, who are critical to the learning process and to the implementationof the  teaching objectives, been the actual proponents of its core content.

Objective: To develop a national-scale proposal of teaching, objectives for the family medicine clerckship in medical school, using a consensus method and the actual, community-based teachers as the expert body.

Method: The Delphi method was chosen for that purpose. In the first round all 189 family medicine teachers in Israeli medical schools were asked to propose five teaching objectives. In the second round the objectives, which were generatedin the first round, were characterized by key words and were send to the participants as a second round for ranking according to their importance.

Results: A total of 116 family medicine teachers (61.38%) responded in the first round and 91 of the 116 (78.5%) in the second round. They formulated 51 teaching objectives listed in order of importance, covering a wide array of themes and including knowledge, attitude and skills objectives. The most important objectives were common problems in primary care, recognition of the biopsychosocial model, and understanding the importance of the doctor-patient relationship. The structure of the list provides a uniqe insight into the relative importance of each objective in the context of the whole core content of the clerkship.

Conclusions: Constructing a proposal for teaching objectives is feasible using the Delphi method and the field instructors as the selecting body. The process and its results can provide faculty with relevant and important suggestions on the content and structure of the family medicine clerkship.
 

Background: The time to recurrence after surgical removal of primary pterygium (pterygium) and the association between the rate of recurrence and the postoperative interval remain unclear.

Objective: To determine the amount of follow-up time needed to identify recurrence in patients after surgical removal of pterygium.

Methods: We rviewed the files of 143 patients (143 eyes) with recurrent pterygium to determine the interval from surgery to recurrence.

Results: Almost all (91.6%) of the recurrences appeared by 360 days after surgery.

Conclusions: One year is the optimal follow-up time to identify recurrence of pterygium.

Background: At the start of the Bone and Joint Decade 2000-2010, a paleopathologic study of the physically disabled may yield information and insight on the prevalence of crippling disorders and attitudes towards the afflicted in the past compared to today.

Objective: To analyze “The procession of the Cripples,” a representative drawing of 31 disabled individuals by Hieronymus Bosch in 1500.

Method: Three specialists - a rhumatologist, an orthopedic surgeon and neurologist - analyzed each case by problem-solving means and clinical reasoning in order to formulate a consensus on the most likely diagnosis.

Result: This iconographic study of cripples in the sixteenth century reveals that the most common crippling disorder was not a neural form of leprosy, but rather that other disorders were also prevalent, such as congenital malformation, dry gangrene due to ergotism, post-traumatic amputations, infectious diseases (Pott’s, syphilis), and even simulators. The drawings show characteristic coping patterns and different kinds of crutches and aids.

Conclusion: A correct clinical diagnosis can be reached through the collaboration of a rheumatologist, an orthopedist and neurologist. The Bone and Joint Decade Project, calling for attention and education with respect to musculoskeletal disorders, should reduce the impact and burden of crippling disease worldwide through early clinical diagnosis and appropriate treatment.
 

Background: Following the recent drought in Ethiopia, the Jewish Agency, aided by the Israel Ministry of Foreign Affairs, launched a medical relief mission to a rural district in Ethiopia in May-August 2000.

Objectives: To present the current medical needs and deficiencies in this representative region of Central Africa, to describe the mission’s mode of operation, and to propose alternative operative modes.

Methods: We critically evaluate the current local needs and existing medical system, retrospectively analyze the mission’s work and the patients’ characteristics, and summar­ize a panel discussion of all participants and organizers regarding potential alternative operative modes.

Results: An ongoing medical disaster exists in Ethiopia, resulting from the burden of morbidity, an inadequate health budget, and insufficient medical personnel, facilities and supplies. The mission operated a mobile outreach clinic for 3 months, providing primary care to 2,500 patients at an estimated cost of $48 per patient. Frequent clinical diagnoses included gastrointestinal and respiratory tract infections, skin and ocular diseases (particularly trachoma), sexually trans­mitted diseases, AIDS, tuberculosis, intestinal parasitosis, malnutrition and malaria.

Conclusions: This type of operation is feasible but its overall impact is marginal and temporary. Potential alternative models of providing medical support under such circum­stances are outlined.
 

Background: The neurosteroids dehydroepiandrosterone (DHEA) and its sulfated metabolite (DHEAS) have been reported to possess neuroprotective as well as anti-tumoral activity in vitro and in vivo.

Objectives: To compare the effect of the two neurohor­mones on cell viability in primary whole-brain fetal mouse culture and isolated neuronal culture, as well as in a human neuroblastoma cell line (SK-N-SH).

Methods: Cell viability and cell proliferation were deter­mined with the neutral red and ³H-thymidine uptake methods, Apoptosis in propidium iodide-stained neuroblastoma cells was determined using flow cytometry.

Results: DHEA (1 nM-10 ìM) decreased the viability of selected primary neuronal cells (33-95% after 24 and 72 hours) but not of whole-brain cultured cells (neuron+glia). DHEAS did not significantly modify cell viability in either primary culture. In a human neuroblastoma cell line, DHEA (1 nM- 1 ìM) decreased ³H-thymidine uptake (30-60%) and cell viability (23-52%) after 24 hours. DHEAS did not significantly modify, or only slightly stimulated, cell viability and uptake of  ³H-thymidine (132% of controls). The combination of DHEA and DHEAS neutralized the toxic effect of DHEA in both primary neuronal culture and neuroblastoma cell line. Flow cytometric analysis of DNA fragmentation in neuroblastoma cells treated with 100 nM DHEA/DHEAS for 24 hours showed an increase in apoptotic events (31.9% and 26.3%. respec­tively, vs. control 2.54%).

Conclusions: Our results do not confirm a neuroprotective role for DHEA and suggest that DHEA and DHEAS have a differential role: DHEA possesses a neurotoxic (expressed only in isolated neurons) and anti-proliferative effect DHEAS demonstrates only a slight neuroprotective effect.
 

Background: Fasting is required by the Jewish and Islamic religions, and may sometimes be necessary for non­religious reasons as well. Very little empiric data are available on the effect of 24 hours of food and water deprivation.

Objectives:  To compare the effects of the dietary composition of different pre-fast meals on subjective discom­fort and various other parameters of a 24 hour food and water fast.

Methods: Thirteen volunteers of both genders participated in a non-randomized crossover study. Each consumed three different equicaloric pre-fast meals in which the main source of calories was protein (49% of calories), carbohydrate (86%), or fat (69%). Weight, heart rate, blood pressure, blood and urine were tested before and after 24 hours of fasting, and the subjective evaluations of the discomfort during the three fasts were compared.

Results: After the protein-rich meal greater discomfort and more side effects were reported. Weight and blood pressure decreased at the end of the fasts that followed each of the three meals heart rate increased after the high fat and carbohydrate meals but not after the protein meal. The main laboratory findings were a 40% increase in blood urea nitrogen and higher urine osmolarity after the protein-rich meal than after the other meals.

Conclusion: A protein-poor pre-fast meal is likely to be followed by easier fasting.
