A. Jotkowitz, A. Porath, A. Shotan, M. Mittelman, E. Grossman, R. Zimlichman, B.S. Lewis, A. Caspi, S. Gottlieb and M. Garty, for the Steering Committee of the Israeli Heart Failure National Survey 2003

Background: Despite significant advances in the therapy of heart failure, many patients still do not receive optimal treatment.

Objectives: To document the standard of care that patients hospitalized with HF[1] in Israel received during a 2 month period.

Methods: The Heart Failure Survey in Israel 2003 was a prospective 2 month survey of patients admitted to all 25 public hospitals in Israel with a diagnosis of HF.

Results: The mean age of the 4102 patients was 73 years and 43% were female. The use of angiotensin-converting enzyme/angiotensin receptor blockers and beta blockers both declined from NYHA class I to IV (68.8% to 50.6% for ACE[2]-inhibitor/ARB[3] and 64.1% to 52.9% for beta blockers, P < 0.001 for comparisons). The percentage of patients by NYHA class taking an ACE-inhibitor or ARB and a beta blocker at hospital discharge also declined from NYHA class I to IV (47.5% to 28.8%, P < 0.002 for comparisons). The strongest predictor of being discharged with an ACE-inhibitor or ARB was the use of these medications at hospital admission. Negative predictors for their usage were age, creatinine, disease severity class, and functional status.

Conclusions: Despite the dissemination of guidelines many patients did not receive optimal care for HF. Reasons for this discrepancy need to be identified and modified.

Background: The prevalence and incidence of blindness in Israel appear to be comparable to other western countries. Comparisons are difficult because of different definitions of blindness, and the uniqueness of the Israeli registry for the blind.

Objective: To characterize the population who were registered as Blind in Israel in the years 1998–2003 and estimate the prevalence and incidence of blindness by age and causes of blindness.

Methods: A retrospective review of the annual report of the National Registry for the Blind in Israel between 1998 and 2003 identified 21,585 blind persons who received a certificate for blindness. Blind persons are identified by ophthalmologists throughout Israel and referred to the Registry of the Blind if they have a visual acuity of 3/60 or worse, or a visual field loss of < 20 degrees in their better eye. This report includes prevalence data on 21,585 persons enrolled in this review still alive and living in Israel in 2003. We estimated the prevalence rate of blindness nationwide and the incidence rate for each cause of blindness for every year.

Results: The main leading causes of blindness in Israel in 1998 were (in percent of the total number of newly registered patients): age-related macular degeneration (20.1%), glaucoma (13.8%), myopic maculopathy (12%), cataract (10.4%), diabetic retinopathy and maculopathy (10.1%), and optic atrophy (7.9%), and in 2003, 28%, 11.8%, 7.4%, 6.5%, 14.4% and 6.5% respectively.

Conclusions: The results indicate that the incidence of age-related macular degeneration, diabetic retinopathy and maculopathy in Israel is increasing, while that of glaucoma, myopic maculopthy, optic atrophy and cataract is decreasing.

A value system that espouses the right of an individual to guard his privacy has moral, theoretical and practical validity, while equal weight must be given, morally, conceptually and socially, to a concept that extols freedom of expression and the public's right to know. The built-in contradiction between these two schools of thought is expressed, inter alia, in the inter-relationship between the media and the medical community when the health of a national leader ceases to be his private affair and becomes the legitimate concern of the public. In Israel, no set rules exist regarding how such situations are reported. This article aims to suggest such a procedure.

 Congenital heart disease is usually regarded as an esoteric field of medicine, dealt with primarily by dedicated specialists. However, over the last two decades a much broader attention has been given by the medical profession, the media and the general public, to the possible association between a minor and common congenital heart defect, namely a patent foramen ovale, and stroke. In recent months, unusual and unfortunate circumstances have made this topic one of the most fiercely debated medical issues in Israel. It is the belief of the authors of this paper that the association of PFO[1] and stroke can be better understood if the PFO is viewed as part of a broader aspect of congenital heart disease, and as such it will be presented. Paradoxical embolism is a mechanism of stroke unique to congenital heart disease. The direction and volume of shunted blood in various conditions have a central role in determining the risk of stroke, as will be explained. With this basic knowledge in mind, we shall critically assess the potential role of PFO in stroke patients, suggesting that each case be evaluated individually using the above-mentioned principles. Conditions that enhance the formation of clot or other embolic material will be discussed briefly. The review will conclude with the various treatment options and our center's own experience with this challenging topic.

 Background: Recent data confirming the oncologic safety of laparoscopic colectomy for cancer as well as its potential benefits will likely motivate more surgeons to perform laparoscopic colorectal surgery.

Objectives: To assess factors related to the learning curve of laparoscopic colorectal surgery, such as the number of operations performed, the type of procedures, major complications, and oncologic resections.

Methods: We evaluated the data of our first 100 elective laparoscopic colorectal operations performed during a 2 year period and compared the first 50 cases with the following 50.

Results: The mean age of the study population was 66 years and 49% were males. Indications included cancer, polyps, diverticular disease, Crohn’s disease, and others, in 50%, 23%, 13%, 7% and 7% respectively. Mean operative time was 170 minutes. One patient died (massive pulmonary embolism). Significant surgical complications occurred in 10 patients (10%). Hospital stay averaged 8 days. Comparison of the first 50 procedures with the next 50 revealed a significant decrease in major surgical complications (20% vs. 0%). Mean operative time decreased from 180 to 160 minutes and hospital stay from 8.6 to 7.2 days. There was no difference in conversion rate and mean number of harvested nodes in both groups. Residents performed 8% of the operations in the first 50 cases compared with 20% in the second 50 cases. Right colectomies had shorter operative times and fewer conversions.

Conclusions: There was a significant decrease in major complications after the first 50 laparoscopic colorectal procedures. Adequate oncologic resections may be achieved early in the learning curve. Right colectomies are less difficult to perform and are recommended as initial procedures.

 Recombinant human erythropoietin has become an essential part of the management of anemic patients with end-stage renal disease. It is also used to treat the anemia associated with cancer and other diseases, and it improves quality of life. In recent years, studies in animals and humans have focused on the use of rHuEPO[1] for other indications. It has been found to play a role in both cardioprotection and neuroprotection. It has effects on the immune system, and can cause regression in hematologic diseases such as multiple myeloma. It may also improve the response of solid tumors to chemotherapy and radiation therapy. On the other hand, concerns have been raised following two studies of patients with solid tumors in whom those treated with rHuEPO had diminished survival. Criticism of the design of these studies makes it clear that large, well-designed, randomized trials must be performed to determine the role of rHuEPO in the treatment of cancer, and more generally to clarify the full clinical benefits of the drug, while minimizing the harm.

Background: Open neural tube defects are among the most common severely disabling birth defects. Secondary prevention by early diagnosis during pregnancy and abortion of affected fetuses lead to a marked reduction of NTD[1] incidence at birth. For primary prevention of these defects, in August 2000 the Israel Ministry of Health issued guidelines recommending a daily 0.4 mg folic acid supplement for all women in their childbearing years with special emphasis on the 3 months preceding conception and the first trimester of pregnancy.

Objectives: To compare the epidemiologic characteristics of NTD in Israel before and after the guidelines for folic acid supplementation.

Methods: A national registry of NTD was begun in 1999. Since the Ministry of Health published the recommendation for folic acid supplementation in mid-2000, the years 1999–2000 represent the status prior to the recommendation and the years 2002–2004 the status after.

Results: A marked decline in the rate of spina bifida was observed in the last 3 years (from 4.9 to 2.7 per 10,000 live births among Jews and 9.5 to 6.2 among Arabs and Druze). There was no apparent reduction for anencephaly.

Conclusions: Following the Ministry of Health guidelines on folic acid supplementation for women in the reproductive age, a marked reduction in the rates of NTD was observed. In light of this apparent success, continuous efforts should be made to increase the percentage of women taking the supplementation and, especially, to introduce folic acid fortification.

Background: Israel, as a country of immigration, has a heterogeneous distribution of risk for human immunodeficiency virus. Therefore, general population-based surveys of sexual behaviors among young adults may be useful for guiding prevention policy. To the best of our knowledge, the present survey is the first one among Israeli adults ever published.

Objectives: To survey knowledge, attitudes and practices regarding sexually transmitted infections in Israeli adults in order to target the future AIDS public campaigns for the general population.

Methods: A national sample of 800 individuals, aged 18–45, was interviewed telephonically in September 2000.

Results: The average number of sexual partners reported in the previous 3 months was 1.3. Accurate knowledge on HIV[1] transmission modes was expressed by 99% of respondents for unprotected sexual intercourse, 97% for re-use of needles and syringes, and 85% for mother-to-child infection. However, incorrect notions on transmission were also prevalent (34% for insect bites, 29% for kissing and 21% for public toilets). Prevention of STIs[2] and prevention of pregnancy were the most common reasons for using condoms (72–73%); HIV prevention was the motivation for 39%. Fifty percent of single individuals without steady partners always/usually used condoms. It was decided that women need empowerment to negotiate condom use.

Conclusions: Gaps were found between knowledge (at high level), attitudes (perceiving greater risk for others than themselves) and behavioral practices (combining low level of partner exchange with widespread disregard for safe sex). Promptly implemented, these findings will serve as a baseline for further surveys.

Background: Endobronchial stents are used to treat symptomatic patients with benign or malignant airway obstructions.

Objectives: To evaluate the safety and outcome of airway stent insertion for the treatment of malignant tracheobronchial narrowing.

Methods: The files of all patients with malignant disease who underwent airway stent insertion in our outpatient clinic from June 1995 to August 2004 were reviewed for background data, type of disease, symptoms, treatment, complications, and outcome.

Results: Airway stents were used in 34 patients, including 2 who required 2 stents at different locations, and one who required 2 adjacent stents (total, 37 stents). Ages ranged from 36 to 85 years (median 68). Primary lung cancer was noted in 35% of the patients and metastatic disease in 65%. Presenting signs and symptoms included dyspnea (82%), cough (11.7%), hemoptysis (9%), pneumonia (5.9%), and atelectasis (3%). The lesions were located in the left mainstem bronchus (31%), trachea (26%), right mainstem bronchus (26%), subglottis (14.3%), and bronchus intermedius (2.9%). Conscious sedation alone was utilized in 73% of the patients, allowing for early discharge. Eighteen patients (50%) received brachytherapy to the area of obstruction. Complications included stent migration (one patient) and severe or minimal bleeding (one patient each). Ninety-four percent of the patients reported significant relief of their dyspnea. Three of the four patients who had been mechanically ventilated before the procedure were weaned after stent insertion. Median survival from the time of stent placement was 6 months (range 0.25–105 months).

Conclusion: Stent placement can be safely performed in an outpatient setting with conscious sedation. It significantly relieves the patient's symptoms and may prolong survival.

Background: Anti-influenza vaccination has proven cost-effective for society. In Israel, however, vaccination rates remain relatively low in comparison to other countries.

Objectives: To analyze the socioeconomic and health status factors affecting the decision to be vaccinated against flu and to compare these factors to results from other countries in order to determine which segments of the adult population should be targeted for increased coverage in influenza vaccination programs.

Methods: Our source was the 1999/2000 Health Survey of the Central Bureau of Statistics for the group aged 25 and above, comprising 16,033 individuals. We used statistical methods such as the Probit regression model to estimate the effects of socioeconomic and health status variables on the decision to get a flu shot. The variables included gender, age, marital status, education, ethnic origin, religious affiliation and housing density, as well as chronic illnesses, smoking, hospitalizations, membership in health management organizations and kibbutz membership.

Results: Our findings indicate that being a post-1990 immigrant from the former Soviet Union, living in a densely populated house, being unmarried and smoking heavily are important factors in predicting the decision not to be vaccinated. In contrast, chronic illness, previous hospitalizations, older age, and kibbutz membership have a positive effect on the decision to take the vaccine.

Conclusions: It is necessary to identify the socioeconomic and health variables marking population sectors that are less likely to be vaccinated in order to design a suitable policy to encourage vaccination.
