Background: While family presence during resuscination has been researched extensively in the international and especially American medical literature, in Israel this subject has rarely been researched. Because such policies have become common practice in many countries, it is important to investigate the attitudes of health care staff in Israeli emergency departments to better understand the potential implication of adopting such policies.

Objectives: To examine the attitudes of the physicians and nurses in the ED of Soroka Medical Center to FPDR[1]. 

Methods: The methods we used were both qualitative (partly structured open interviews of 10 ED staff members from various medical professions) and quantitative (an anonymous questionnaire that collected sociodemographic, professional, and attitude data).

Results: The qualitative and quantitative results showed that most staff members opposed FPDR. The main reasons for objecting to FPDR were concern about family criticism, the added pressure that would be put on the staff members, fear of lawsuits, fear of hurting the feelings of the families, and the danger of losing one’s objectivity while treating patients. Physicians objected more strongly to FPDR than did nurses.  

Conclusions: More research is needed on FPDR in Israel, including an examination of its medical, ethical, legal and logistic aspects. In addition to the views of the medical staff, the attitudes of patients and their families should also be examined.

Background: Autoimmune neutropenia of infancy is caused by neutrophil-specific autoantibodies. Primary AIN[1] is characterized by neutrophil count < 500 ml and a benign self-limiting course. Detecting specific antibodies against the polymorphic human neutrophil antigen usually confirms the diagnosis. Current available tests, however, are expensive and inapplicable in many laboratories as they require the use of isolated and fixed granulocytes obtained from donors pretyped for their distinct HNA[2] alloform.

Objectives: To assess the performance of a modified test to identify by FACS-analysis granulocyte-specific antibodies in the sera of neutropenic children.

Methods: We evaluated 120 children with a clinical suspicion of AIN, whose sera were analyzed by flow cytometry for the presence of autoantibodies using the indirect granulocyte immunofluorescence test. In contrast to the traditional tests, the sera were tested against randomly selected untyped neutrophils derived from a batch of 10 anonymous healthy subjects, presumably including the common HNA alloforms. Control sera samples were from patients with chemotherapy-induced, familial or congenital neutropenias. To further assure the quality of the new test, we retested six samples previously tested by the gold standard method. All medical files were screened and clinical outcomes were recorded.

Results: Our method showed specificity of 85%, sensitivity of 62.5%, and a positive predictive value of 91.8%, values quite similar to those obtained by more traditional methods.

Conclusions: The new method showed high specificity for detection of anti-neutrophil antibodies in the appropriate clinical setting and could be an effective aiding tool for clinical decision making.

Background: According to the Israeli immunization schedule 1 year old babies should receive two concomitant vaccinations: MMR (measles-mumps-rubella), and DTap-Hib-IPV (diphtheria tetanus acellular pertussis-Haemophilus influenzae type b-poliomyelitis). However, about one-third of infants in Israel receive these vaccinations separately. Nurses at a primary care prevention clinic in Israel observed that the separate mode of vaccination is associated with a lower rate of side effects.

Objectives: To validate this observation and determine whether it represents an exception or the rule.

Methods: A nested prospective follow-up study was conducted in a primary care clinic in Israel. The survey included 191 mothers and their offspring born during 2004/2005. The mothers were interviewed over the telephone 2 weeks after the day of vaccination.

Results: The rate of adverse effects in children who received the injections separately was significantly lower than among those who were vaccinated simultaneously (40% vs. 57%).

Conclusions: It may be necessary to reconsider the current vaccination policy regarding concomitant injections.

Background: The incidence of stroke varies among ethnically and culturally diverse groups.

Objectives: To examine the ethnic-geographic patterns of stroke incidence in men and women with coronary heart disease in Israel, focusing on the extent to which this variability can be explained by known differences in risk factors for stroke.

Methods: Patients with documented coronary heart disease were followed for 6–8 years for incident cerebrovascular events. Baseline medical evaluation included assessment of vascular risk factors and measures of blood lipids. Among 15,052 patients, a total of 1110 were identified with any incident ischemic cerebrovascular event by ICD-9 codes, of whom 613 had confirmed ischemic stroke or transient ischemic attack.

Results: A major excess of ischemic cerebrovascular events among Israeli Arab women as compared to males, and an inverse finding among Israeli born Jews, were noted. The high risk in the Arab population in Israel reflected an unfavorable risk profile, since predicted rates by multivariate analysis and observed rates were 69 and 68 per 1000, respectively. High ischemic cerebrovascular event rates were identified among patients born in the Balkan countries and North Africa (89 and 90 per 1000) but unfavorable risk factor levels of these individuals did not explain them. Most trends appeared similar in male and female patients. A comparison of observed and accepted-according-to-risk-profile rates of ischemic cerebrovascular events yielded significant differences (P = 0.04), consistent with an additional role of geographic/ethnic origin, resulting from factors that remain unrecognized,or with variables unassessed in this study.

Conclusions: We identified an ethnic diversity in stroke risk among Israeli born in different parts of the world beyond what could be expected on the basis of differences in known risk factors. These findings call for detailed research aimed at identifying additional differences in the risk profile of patients with atherothrombotic disease exposed to an increased risk of stroke.
 

Background: Radiological procedures utilizing intravascular contrast media are being widely applied for both diagnostic and therapeutic purposes. This has resulted in increasing incidence of procedure-related contrast-induced nephropathy. In Israel, data on the incidence of CIN[1] and its consequences are lacking.

Objectives: To describe the epidemiology of CIN among hospitalized patients in the Western Galilee Hospital, Nahariya (northern Israel), and to explore the impact of CIN on mortality and length of stay.

Methods: The study group was a historical cohort of 1111 patients hospitalized during the year 2006 who underwent contrast procedure and whose serum creatinine level was measured before and after the procedure. Data were electronically extracted from different computerized medical databases and merged into a uniform platform using visual basic application.

Results: The occurrence of CIN among hospitalized patients was 4.6%. Different CIN rates were noticed among various high risk subgroups such as patients with renal insufficiency and diabetes mellitus (14.1%–44%). Average in-hospital length of stay was almost twice as long among patients with CIN compared to subjects without this condition. Furthermore, the in-hospital death rate among CIN patients was 10 times higher. A direct association was observed between severity of CIN based on the RIFLE classification and risk of mortality.

Conclusions: Low CIN occurrence was demonstrated in the general hospitalized patients (4.6%), and high rates (44%) in selected high risk subgroups of patients (with renal insufficiency or diabetes mellitus). Furthermore, prolonged length of stay and high in-hospital mortality were directly related to CIN severity.

Background: Chronic heart failure is associated with excessive hospitalizations and poor prognosis.

Objectives: To summarize the 5 year experience of a single-center CHF[1] day care service, detect the cardiovascular and non-cardiovascular events, and evaluate the safety of the treatments provided.

Methods: We retrospectively studied all patients admitted to the CHF day care service of the Sheba Medical Center between September 2000 and September 2005.

Results: Advanced (New York Heart Association class III-IV) CHF patients (n=190), mean age 65 ± 12 years and left ventricular ejection fraction 25 ± 11%, were treated for 6 hourly biweekly visits; 77% had ischemic and 23% had non-ischemic cardiomyopathy. Treatment included: intravenous diuretic combinations (91%), intermittent low dose (≤ 5 mg/kg/min) dobutamine (87%), low dose (≤ 3 mg/kg/min) dopamine (38%), intravenous iron preparation and/or blood (47%), and intravenous nitropruside (36%). Follow-up of at least 1 year from initiation of therapy was completed in 158 of 190 patients (83%). Forty-six (29.3%) died: 23% due to CHF exacerbation, 5.7% from infection, 4.4% from sudden cardiac death, 3.8% from malignancy, 2.5% from malignant arrhythmias, 1.9% from renal failure, 1.3% from stroke, and 0.6% from myocardial infarction. There were only 0.68 rehospitalizations/patient/year; the most frequent cause being CHF exacerbation (16.5%).

Conclusions: Our study demonstrates the safety and potential benefits of a supportive day care service for advanced CHF patients. Multidrug intravenous treatment, accompanied by monitoring of electrolytes, hemoglobin and cardiac rhythm, along with education and psychological support, appear to reduce morbidity in advanced CHF patients and may have contributed to the lower than expected mortality/hospitalization rate.

Background: Magnetic resonance imaging of the breast has emerged as a valuable imaging tool in addition to conventional imaging modalities. It has high sensitivity for malignant lesions, and can detect mammographically, sonographically and clinically occult cancers. “MR only” lesions are best biopsied under MR guidance; however, this may be a challenging task.

Objectives:  To evaluate our initial clinical experience with MR-guided core needle breast biopsy and MR-guided needle localization.

Methods: We retrospectively evaluated 81 women with 97 lesions, who were scheduled for guided core needle biopsy or MR-guided needle localization followed by surgery. Lesions were categorized as malignant, high risk, or benign according to the BI- RADS MR classification system. MR findings were compared with final histopathology or with follow-up imaging findings.

Results: Fifteen (16%) lesions were malignant (9 invasive ductal carcinoma, 2 invasive lobular carcinoma, 4 ductal carcinoma in situ); 7 (7%) lesions were high risk (4 atypical ductal hyperplasia, 3 radial scars); 75 (77%) lesions were benign, mainly fibrocystic changes. Other benign findings were sclerosing adenosis, pseudoangiomatous stromal hyperplasia, fat necrosis, intraductal papilloma, fibroadenoma, capillary hemangioma, and florid ductal hyperplasia. No major complications were encountered.
Conclusions: MR-guided interventional procedures of the breast are accurate, safe and feasible methods for sampling breast lesions detected only by MR and have become a significant tool in the management of certain patients.
