Background: The osteoporosis-pseudoglioma syndrome is a rare autosomal recessive disorder characterized by severe juvenile-onset osteoporosis and congenital or early-onset blindness. Other manifestations include muscular hypotonia, ligamentous laxity, mild mental retardation and seizures. The gene responsible was recently identified to be the low density lipoprotein receptor-related family member LRP5 on chromosome 11q11-12.

Objective: To measure bone density in two siblings with the OPPG[1] syndrome as well as in their family members (parents and siblings).

Methods: Bone mineral density was determined in the lumbar spine (antero-posterior), femoral neck, two-thirds distal forearm (>95% cortical bone) and ultradistal forearm (predominantly trabecular bone) by dual-energy X-ray absorptiometry.

Results: The studies revealed osteoporotic changes both in the patients and the carriers.

Conclusion: The findings demonstrate that OPPG carriers have reduced bone mass, which is a risk factor for development of early osteoporotic changes.

Background: Bleeding in the first trimester of pregnancy is a common phenomenon, associated with early pregnancy loss. In many instances a subchorionic hematoma is found sonographically.

Objective: To evaluate the possible benefit of bed-rest in women with threatened abortion and sonographically proven subchorionic hematoma, and to examine the possible relationship of duration of vaginal bleeding, hematoma size, and gestational age at diagnosis to pregnancy outcome.

Methods: The study group consisted of 230 women of 2,556 (9%) referred for ultrasound examination because of vaginal bleeding in the first half of pregnancy, who were found to have a subchorionic hematoma in the presence of a singleton live embryo or fetus. All patients were advised bed-rest at home; 200 adhered to this recommendation for the duration of vaginal bleeding (group 1) and 30 continued their usual lifestyle (group 2). All were followed with repeated sonograms at 7 day intervals until bleeding ceased, the subchorionic hematoma disappeared, or abortion occurred. The groups were compared for size of hematoma, duration of bleeding, and gestational age at diagnosis in relation to pregnancy outcome (spontaneous abortion, term or preterm delivery).

Results: The first bleeding episode occurred at 12.6 ± 3.4 weeks of gestation (range 7–20 weeks) and lasted for 28.8 ± 19.1 days (range 4–72 days). The women who adhered to bed-rest had fewer spontaneous abortions (9.9% vs. 23.3%, P = 0.006) and a higher rate of term pregnancy (89 vs. 70%, P = 0.004) than those who did not. There was no association between duration of vaginal bleeding, hematoma size, or gestational age at diagnosis of subchorionic hematoma and pregnancy outcome.

Conclusions: Fewer spontaneous abortions and a higher rate of term pregnancy were noted in the bed-rest group. However, the lack of randomization and retrospective design of the outcome data collection preclude a definite conclusion. A large prospective randomized study is required to confirm whether bed-rest has a real therapeutic effect.

Background: Cystinuria is an autosomal recessive disease that is manifested by the development of kidney stones. Mutations in SLC3A1 cause type I disease, while mutations in SLC7A9 are associated with non-type I disease. In Israel cystinuria is especially common among Libyan Jews who suffer from non-type I disease.

Objectives: To compare clinical manifestations of patients with mutations in SLC3A1 to those with mutations in SLC7A9, and to assess the carrier rate among unaffected Libyan Jewish controls.

Methods: Clinical manifestations were evaluated in patients with mutations in SLC3A1 and in patients with mutations in SLC7A9. Carrier rates for two SLC7A9 mutations were assessed in 287 unaffected Libyan Jewish controls.

Results: Twelve patients with mutations in SLC3A1 were compared to 15 patients with mutations in SLC7A9. No differences were detected between the patients with mutations in SLC3A1 and those with mutations in SLC7A9 in relation to the age of disease onset, the estimated number of stones, the number of invasive procedures, the number of patients receiving drug therapy, or the patients’ urinary pH. Eleven of the unaffected Libyan Jewish controls were found heterozygotes for the V170M mutation, establishing a carrier rate of 1:25. The 1584+3 del AAGT mutation was not found in any of the Libyan Jewish controls.

Conclusion: Mutations in SLC3A1 and SLC7A9 cystinuria patients result in indistinguishable disease manifestations. The high carrier rate among Libyan Jews is a result of a single missense mutation, V170M.

Since the early 1980s demographic changes compelled Israel’s health system to dedicate efforts to establish modern geriatric services. This task was performed with the help of governmental and non-governmental institutions and was coordinated by the Division of Geriatrics and Long-Term Care Diseases of the Ministry of Health. Today, 20 years later, as a result of those efforts, geriatrics and geriatric services in Israel are thriving. Qualified staff, including physicians who specialized in geriatrics, are working to maintain a high quality of care in various geriatric settings. However, more resources should be allocated for research in order to maintain and to continue to develop geriatric medicine in Israel.

Background: An important question on the health agenda concerns the most appropriate place to hospitalize stroke patients and its effect on acute stroke care.

Objectives: To examine how the existing hospital system treats these patients, specifically: a) the departments to which stroke patients are admitted; b) differences in the admission, diagnosis and rehabilitative care of stroke patients, by department; c) patient characteristics, by department; and d) mortality rates during hospitalization.

Methods: We surveyed 616 people with acute stroke (ICD-CM9 430-433, 436) admitted consecutively to one of seven large general hospitals in Israel between October 1998 and January 1999. Data were collected from medical records at admission and at discharge.

Results: Forty-two percent of the patients were admitted to an internal medicine department, 56% to a neurology department, and only 2% to a geriatric department. The majority (95%) underwent a computed tomography scan of the brain, but other imaging tests were performed on fewer patients, with significant differences among hospitals and between internal medicine and neurology departments. Patients admitted to neurology departments were younger and had milder stroke symptoms than did patients admitted to internal medicine departments. Fifty-three percent of patients received at least one type of rehabilitative care during their hospital stay – usually physiotherapy, and least often occupational therapy. Seventeen percent of stroke patients died during hospitalization. Mortality was not found to be related to the admitting department.

Conclusions: Uniform realistic policies and work procedures should be formulated for all hospitals in Israel regarding the admitting department and processes as well as the performance of diagnostic imaging. Standards of medical and rehabilitative care and discharge destination should be developed to promote quality of care while containing utilization and costs.

Background: Due to multiple chronic illness and disability, the elderly consume a disproportionately large share of medications.

Objectives: To assess the patterns and determinants of drug use among the community dwelling old-old population.

Methods: The study population included 1,369 old-old persons from the baseline data of the Cross-Sectional and Longitudinal Aging Study (CALAS), which is based on a national random stratified sample of the Israeli Jewish population aged 75–94 years.

Results: The mean number of drugs used by the study population was 3.3, and only 12.5% did not consume any drugs. Multivariate linear regression analysis showed that women used significantly more drugs than men, and that those born in Europe took significantly more drugs than those born in Israel and Asia-Africa. The number of medical conditions was the strongest predictor of drug use. Hospitalizations during the last year and frequent visits to family physician were also significant factors related to drug use. All variables combined explained 40% of the variance in drug use by the old-old. The most commonly used therapeutic groups were cardiovascular drugs (53%), psychotropic drugs (31%), analgesics (30%), and gastrointestinal drugs (28%).

Conclusions: Our data indicate that in addition to the association of drug use with health status and healthcare utilization, the number and type of drugs taken vary with gender and place of birth.

In 2001 the number of residents aged 65 and over in Israel was 639,000, or 10% of the population. The rate of increase of the elderly population is twice that of the general population, thus the predicted number of elderly for 2020 is around 1,025,000, representing a 60% increase. While this process is determined by a decline in both fertility and mortality, in Israel, immigration has also been a central factor in the process of aging. Life expectancy stands at 76.7 for men and 80.9 for women; at age 65 it is 16.4 years for men and 18.5 for women. The major factor influencing the increase in life expectancy during the past two decades has been the prevention of death among older people. Population aging, or “the demographic transition,” also represents an "epidemiological transition” – from high rates of infectious and communicable diseases, to high rates of chronic diseases among older people. During the past two decades, the number of disabled elderly has increased more than 2.5 times. In 2001, there were about 97,400 disabled elderly in Israel, constituting about 15% of all elderly. By the year 2010, the number of disabled elderly is expected to reach 120,100. The rate of increase of the disabled elderly population is almost double that of the total elderly population, due to changes in this population’s composition. However, recent research indicates that new cohorts of elderly are healthier than earlier cohorts but experience a decline in health at older ages. While advances in standard of living, medicine, and technology have made this possible, a greater allocation of resources is required to prevent disability and maintain the quality of life.

The Arab population of Israel is relatively young. However, a significant increase is expected in the number of elderly Arabs in the coming years. At the end of 2001 there were 38,500 Arab elderly, but their number is expected to reach 92,100 by 2020. This will represent a nearly 2.5-fold increase in absolute numbers. As the population ages, the number and percentage of people with chronic diseases and related disabilities will rise significantly. While the Arab elderly are much younger than the Jewish elderly, they are more disabled and therefore have greater medical and nursing needs. An extremely important measure of the need for formal services is an elderly person’s functional ability, especially the ability to live independently. The percentage of Arab elderly who are disabled and need help with activities of daily living is two times higher than that of the Jewish elderly population. At present, 30% of the Arab elderly (39% of the women and 20% of the men), compared to 14% of Jewish elderly (17% of the women and 11% of the men), need help in at least one ADL[1] (bathing, dressing, eating, mobility in the home, rising and sitting, getting in and out of bed). Concomitant with demographic changes are forces that affect the ability of informal support systems to provide care. For example, the rising number of Arab women in the labor force together with changes in elderly peoples' living arrangements have increased the need for formal services to share responsibility for the elderly with families. As services are developed, questions arise regarding the extent to which they have been adapted to the culture and norms of Arab society and meet that society’s unique needs. This paper elaborates on some of these issues.

Background: Little information is available on the clinical practice and implementation of guidelines in treating acute myocardial infarction patients in Israel.

Objective: To assess patient characteristics, hospital course, management, and 30 day clinical outcome of all AMI[1] patients hospitalized in Israel during a 2 month period in 2000.

Method: We conducted a prospective 2 month survey of consecutive AMI patients admitted to 82 of 96 internal medicine departments and all 26 cardiac departments operating in Israel in 2000. Data were collected uniformly by means of a hospital and 30 day follow-up form.

Results: During the survey 1,683 consecutive patients with a discharge diagnosis of AMI were included. Their mean age was 66 years; 73% were male. The electrocardiographic pattern on admission revealed ST elevation, non-ST elevation and an undetermined ECG[2] in 63%, 34% and 4% of patients respectively. Aspirin and heparin were given to 95% of patients. Beta-blockers and angiotensin-converting enzyme inhibitors were given to 76% and 65% of patients respectively. Among hospital survivors, 45% received lipid-lowering drugs. Thrombolytic therapy was administered in 28% of patients, coronary angiography was used in 45%, and 7% of patients underwent primary percutaneous coronary intervention. The 7 and 30 day mortality rates were 7% and 11% respectively.

Conclusions: This nationwide survey shows that one-third of the AMI patients in Israel are elderly (≥ 75 years). The survey suggests that clinical guidelines for the management of patients with AMI are partially implemented in the community. Data from large surveys representing the "real world" practice are of utmost importance for the evaluation of clinical guidelines, research and educational purposes.

Micronutrient deficiencies have reoccupied the center stage of public health policy with the realization that folic acid deficiency results in neural tube defects and possibly other birth defects as well as ischemic heart disease. These, in turn, have raised an older debate on food fortification policy for the elimination of iodine, iron and vitamin D deficiencies. Data from the First Israeli National Health and Nutrition Survey (MABAT 2000) provided an impetus to develop an active national nutrition policy aimed to improve the nutritional status of iodine, iron, vitamins A and D and B-vitamins, including folate. In this paper we examine some of the MND[1] issues in Israel and their implications for public health, and suggest options for the formulation of policy.

Background: The 13C-urea breath test is the best non-invasive test to validate Helicobacter pylori eradication. Serology is unreliable for this purpose due to the slow and unpredictable decline in the antibodies titer.

Objectives: To characterize a specific group of patients who were treated for H. pylori and tested for successful eradication by 13C-UBT[1] in our central laboratory and to correlate the eradication success rate with specific drug combinations, and to evaluate other factors that may influence eradication success.

Methods: 13C-UBT for H. pylori was performed in the central laboratory of Clalit Health Services. The breath test was performed by dedicated nurses in 25 regional laboratories and the samples were analyzed by a mass spectrometer (Analytical Precision 2003, UK). The physician who ordered the test completed a questionnaire computing demographic data (age, gender, origin), indication, use of non-steroidal anti-inflammatory drugs or proton pump inhibitor, and combination of eradication therapy.

Results: Of the 1,986 patients tested to validate successful H. pylori eradication, 539 (27%) had a positive test (treatment failure group) and 1,447 (73%) had a negative test (successful treatment group). Male gender, older age and European-American origin predicted better eradication rates. Dyspeptic symptoms and chronic PPI[2] therapy predicted treatment failure. Combination therapy that included clarithromycin had a higher eradication rate than a combination containing metronidazole. The combination of omeprazole, amoxicillin and clarithromycin achieved an eradication rate of 81.3%, which was better than the combination of omeprazole, metronidazole and clarithromycin (77.2%) (not significant), or of omeprazole, amoxicillin and metronidazole (66.1%) (P < 0.01).

Conclusion: Gender, age, origin, dyspepsia and PPI therapy may predict H. pylori eradication results. Our findings also support an increase in metronidazole resistance of H. pylori strains in Israel, as described in other countries. We recommend combination therapy with omeprazole, amoxicillin and clarithromycin and avoidance of metronidazole as one of the first-line eradication drugs.
