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: Acute scrotal pain in children presents a major diagnostic and therapeutic challenge. Epididymitis has been considered uncommon in childhood. The clinical spectrum and therapeutic policy of the acute scrotum in children is continually being reassessed.

Objectives: To determine whether there has been an increase in the incidence of epididymitis in children and to advocate a more selective surgical approach to the acute scrotum.

Methods: We conducted a retrospective review of 65 children admitted to our department of pediatric surgery with the diagnosis of acute scrotum during a 5 year period.

Results: Of the 65 children admitted with the diagnosis of acute scrotum, epididymitis was diagnosed in 42 (64.6%). The remaining cases included torsion of the testis in 12 patients (18.5%), torsion of the appendix testis in 5 (7.7%), scrotal pain and minimal physical findings in 4 (6.1%), and scrotal hematoma and idiopathic scrotal edema in one patient each. Doppler ultrasound of the groin, color Doppler ultrasound of the testis and testicular nuclide scintigraphy (Tc-99m scan) examinations were performed on 49, 30 and 57 occasions, respectively; the Tc-99m scan was the most effective tool. All the patients with epididymitis were diagnosed before surgical intervention and were treated conservatively.

Conclusions: We observed an increasing frequency of epididymitis in children admitted with the diagnosis of acute scrotum.
 

Background: The evaluation of hospitalized patients with chest pain and non-diagnostic electrocardiogram is problematic and the optimal cost-effective strategy for their management controversial.

Objectives: To determine the utility of myocardial perfusion imaging with thallium-201 for predicting outcome of hospitalized patients with chest pain and a normal or non-diagnostic ECG.

Methods: On pain cessation, 109 hospitalized patients, age 61+14 years (mean+SD), with chest pain and non-diagnostic ECG underwent stress myocardial perfusion SPECT imaging with thallium-201. Costs related to their management were calculated. The occurrence of non-fatal myocardial infarction or cardiac death was recorded at 12+5 months follow-up.

Results: A normal SPECT was found in 84 patients (77%). During one year follow-up, only 1 (1.2%) compared to 7 (28%) cardiac events (6 myocardial infarctions, 1 cardiac death) occurred in patients with normal versus abnormal scans respectively (P < 0.0001). Negative predictive value and accuracy of the method were 99% and 83% respectively. Multivariate regression analysis identified an abnormal SPECT as the only independent predictor of adverse cardiac event (P = 0.0016). Total cost from admission until discharge was 11,193 vs. 31,079 shekels (P < 0.0001) for normal and abnormal scan. Considering its high negative predictive value, shortening the hospital stay from admission until scan performance to 2 days would result in considerably reduced management costs (from NIS 11,193 to 7,243) per patient.

Conclusion: Stress SPECT applied to hospitalized patients with chest pain and a normal or non-diagnostic ECG is safe, highly accurate and potentially cost effective in distinguishing between Iow and high risk patients.
 

Background: Many women stop smoking before or during pregnancy, or while breast-feeding (nursing).

Objectives: To assess the relation between breast-feeding and smoking habits.

Methods: A survey was conducted among 920 women attending family health clinics (group 1) and a maternity department (group 2) on their breast-feeding and smoking habits.

Results: A total of 156 women (16.95%) smoked during pregnancy. A significant correlation was found between breast-feeding and not smoking after delivery (P=0.009 in group 1, P=0.03 in group 2). A higher tendency to nurse was found among women with an uneventful pregnancy, who vaginally delivered a singleton at term weighing 2,500-4000 g, and who received guidance on breast-feeding.

Conclusion: Professional guidance in favor of breast­feeding is crucial to increase the rate of nursing. Encouraging breast-feeding will probably decrease the rate of cigarette smoking.
 

Background: Familial nephritis is a heterogeneous group of disorders caused by several genetic conditions such as Alport syndrome, glomerulonephritic syndromes, and unclas­sified nephritis without deafness or ocular defects.

Objectives: To describe a family of Iraqi Jewish origin, several of whose members suffer from non-syndromic renal failure without deafness or ocular defects and where transmis­sion is by autosomal dominant inheritance. We present the case histories of four family members and describe the molecular analysis performed in order to seek a possible linkage to one of the genes causing Alport or Alport-like syndromes.

Methods: We investigated all family members over the age of 18 for evidence of renal failure. We also extracted DNA and carried out molecular linkage analysis with polymorphic markers in each of the known loci involved in Alport and Alport­like syndromes.

Results: Histology of the renal biopsy specimens showed non-specific findings. Linkage was excluded for all the Alport and Alport-like syndrome loci.

Conclusions: The condition suffered by several members of this family seems to represent a unique autosomal dominant type of progressive hereditary nephritis, characterized by hypertension and progressive renal failure without significant hematuria or proteinuria. The main histological changes are non-specific in the early stage of the disease. Our study rules out all the currently known genes that cause Alport syndrome as being responsible for the basic defect in this type of nephritis.

Objective: To explore the putative effect of cardiac rehabilitation programs on the health-related quality of life’ and ‘return to work’ in pre-retirement patients one year after coronary artery bypass grafting.

Methods: Of the 2085 patients aged 45-4 who survived one year after CABG and were Israeli residents, 145 (6.9%) had participated in rehabilitation programs. Of these, 124 (83%) who answered QOL questionnaires were individually matched with 248 controls by gender, age within 5 years. and the time the questionnaire was answered. All patients had full clinical follow-up including a pre-operative interview. The Short Form-36 QOL questionnaire as well  as a specific questionnaire were mailed to surviving patients one year after surgery. Study outcomes included the scores on eight scales and two summary components of the SF-36, as well as return to work’ and ‘satisfaction with medical services’ from the specific questionnaire. Analysis was done for matched samples.

Results: Cardiac rehabilitation participants had signifi­cantly higher SF-36 scores in general health, physical functioning, and social functioning. They had borderline significant higher scores in the physical summary component of the SF-36. The specific questionnaire revealed significantly better overall functioning, higher satisfaction with medical care. and higher rate of return to work. While participants in cardiac rehabilitation and their controls were similar in their socio­-demographic and clinical profiles, participating patients tended to be more physically active and more fully employed than their controls.

Conclusions: Rehabilitation participants had a self-per­ception of better HRQOL, most significantly in social function­ing. Our findings of more frequent return to work and higher satisfaction with medical care should induce a policy to encourage participation in cardiac rehabilitation programs after CABG.
 

Background: Between 1970 and 1979, there was an increase in the incidence of viral hepatitis in Israel with a shift of peak incidence to an older age in the Jewish population, followed by a declining trend during the early 1980s. In July 1999 universal immunization of infants against hepatitis A was introduced.

Objective: To evaluate the chan-ges in the epidemiology of viral hepatitis A in Israel during the past decade.

Methods: Viral hepatitis is a notifiable disease in Israel and cases are reported to the regional health offices, which in turn provide summary reports to the Ministry of Health's Department of Epidemiology. The data in this study were derived from the summary reports and from results of seroprevalence studies.

Results: Following the increase in the incidence of reported viral hepatitis (mainly due to type A) between 1970 and 1979, the rates then stabilized and around 1984 began to decline until 1992. Since then there has been a slight increase. Whereas until 1987 the rates were consistently higher in the Jewish population. since then they are higher in the Arab population. The shift in the peak age-specific incidence from the 1-4 to the 5-9 year age group observed in the Jewish population around 1970 occurred 20 years later in the Arab population. The previously described seasonality is no longer evident. Recent seroprevalence studies indicate that by age 18 years only about 30-40% of the Jewish population have anti-hepatitis A antibodies.

Conclusions: The decline in the incidence of hepatitis probably reflects the changing socioeconomic condition occurring at different times in the two major population groups. Since hepatitis A accounts for almost all the acute viral hepatitis in Israel, the universal vaccination of infants introduced in 1999 should substantially lower the morbidity within the next few years.

Background: Classic Kaposi's sarcoma is a rare tumor with an indolent behavior. Local therapy is not applicable in disseminated cutaneous disease. Patients with advanced disease are usually treated with systemic chemotherapy.

Objectives: To assess the effectiveness and toxicity of  single-agent vinblastine in the treatment of disseminated and recurrent Kaposi's sarcoma.

Methods: Ten patients with wide cutaneous spread of classic Kaposis sarcoma were treated with single-agent vinblastine, 6 mg/m² intravenously once every 2 weeks. Vinblastine was continued for 2 months after achieving a maximal response.

Results: The male:female ratio was 2.3:1, and median age 64 years (range 50-79 years). The median number of involved nodules in the skin was 34. The overall response rate was 90%, 5 with complete response (50%) and 4 with partial response (40%). Complete responders had a longer duration of response than partial responders: 41.2 vs. 14.8 months. The median survival of all patients was 33 months. Side effects were minimal and tolerable.

Conclusions: Vinblastine is very effective in the treatment of extensive classic Kaposi's sarcoma, and results in a high response rate, long survival and disease-free survival with tolerable toxicity.

Background: Asthma, allergic rhinitis, and atopic derma­titis are leading causes of chronic diseases in developed countries, with at least one allergic condition troubling 10 to 20% of the general population. The few studies performed in Israel determined the prevalence of allergic conditions in selected populations (schoolchildren and soldiers) no study representative of the general population has previously been done.

Objectives: To determine the prevalence of allergic conditions in the general population in Israel and the differences between ethnic and socioeconomic groups.

Method: Using a computer-assisted telephone interview, a telephone questionnaire was conducted in a representative sample of the general Israeli population.

Results: Of the population studied, 140/a claimed to have bronchial asthma, 14% allergic rhinitis, and 6% other allergic conditions. Prevalence rates were higher in the Israeli Arab population and in those with low income and low education levels. Of those with allergic conditions, 58% were treated by a primary physician, 32% were not treated at all, and only 10% were treated by a different specialist physician.

Conclusions: The prevalence of allergic conditions in this study concurs with that found by other studies in developed countries. Allergic conditions are higher in the Israeli Arab population and in those with low income and low education level.
