Background: Guidelines are frequently under-implemented in older patients with heart failure. Octogenerians are often excluded from clinical trials.

Objectives: To characterize the clinical profile of the oldest-old (age ≥ 80 years) heart failure patients hospitalized in a subacute geriatric hospital and to evaluate their management and 1 year outcome.

Methods: Patient characteristics and in-hospital course were retrospectively collected. Diagnosis of heart failure was based mainly on clinical evaluation in addition to chest X-ray results and echocardiographic findings when available.

Results: The study population comprised 96 consecutive unselected heart failure patients hospitalized from January to June 2003. The patients were predominantly women (67%), aged 85 ± 5 years, fully dependent or frail with a high rate of comorbidities. Adherence to guidelines and recommended heart failure medications was poor. Their 1 year mortality was 57%. According to logistic regression analysis, predictors of 1 year mortality were lower body mass index (odds ratio 0.86, 95% confidence interval 0.78–0.96) and high urea levels (OR[1] 1.04, 95% CI[2] 1.02–1.06).

Conclusions: Our study confirms that the management of oldest-old heart failure patients hospitalized in a subacute geriatric hospital was suboptimal and their mortality was exceptionally high.

Background: Health care workers bear the risk of both contracting influenza from patients and transmitting it to them. Although influenza vaccine is the most effective and safest public health measure against influenza and its complications, and despite recommendations that HCWs[1] should be vaccinated, influenza vaccination coverage among them remains low.

Objectives: To characterize influenza vaccination coverage and its determinants among employees in an Arab hospital in Israel.

Methods: An anonymous, self-administered questionnaire was distributed among employees involved in patient care in the winter of 2004–2005 at Nazareth Hospital in Israel. The questionnaire included items related to health demographic characteristics, health behaviors and attitudes, knowledge and attitude concerning influenza vaccination, and whether the respondent had received the influenza vaccine during the previous winter or any other winter.

Results: The overall rate of questionnaire return was 66%; 256 employees participated in the study. The immunization coverage rate was 16.4%, similar to that reported for other hospitals in Israel. Logistic regression analysis demonstrated a significant association only between influenza vaccination coverage and the presence of chronic illness and influenza vaccination in the past.

Conclusions: Influenza vaccination coverage among Nazareth Hospital health care workers was low. They did not view themselves as different to the general population with regard to vaccination. An intervention program was launched after the study period, aimed at increasing the knowledge on the efficacy and safety of the vaccine, stressing the importance of vaccinating HCWs, and administering the vaccine at the workplace. The program raised the vaccination coverage to 50%.

Background: Myocardial blush grade is a useful marker of microvascular reperfusion that may influence left ventricular dilatation.

Objectives: To assess the impact of myocardial blush grade on LV[1] remodeling in patients undergoing successful primary  PCI³ for first anterior ST elevation myocardial infarction.

Methods: In 26 consecutive patients MB[2] grade was evaluated immediately after primary PCI[3]. Each patient underwent transthoracic echocardiography at 24 hours and 6 months after PCI for evaluation of LV volumes. LV remodeling was defined as an increase in end-diastolic volume by ≥ 20%.

Results: The presence of myocardial reperfusion (MB 2-3) after primary PCI was associated with a significantly lower rate of remodeling than the absence of myocardial reperfusion (MB 0-1) (17.6% vs. 66.6%, P = 0.012). Accordingly, at 6 months, patients with MB 2-3 had significantly smaller LV end-diastolic volume (94 ± 21.5 ml vs. 115.2 ± 26) compared with patients with MB 0-1. In univariate analysis, only MB (0-1 versus 2-3) was associated with increased risk of LV remodeling (odds ratio 9.3, 95% confidence interval 1.45–60.21, P = 0.019).

Conclusions: Impaired microvascular reperfusion, as assessed by MB 0-1, may be associated with LV remodeling in patients with STEMI[4] treated successfully with primary PCI.

Pathological gambling is classified in the DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders) and in the ICD-10 (International Classification of Disease) as an impulse control disorder. The association between impulsivity and pathological gambling remains a matter of debate: some researchers find high levels of impulsivity within pathological gamblers, others report no difference compared to controls, and yet others even suggest that it is lower. In this review we examine the relationship between pathological gambling and impulsivity assessed by various neurocognitive tests. These tests – the Stroop task, the Stop Signal Task, the Matching Familiar Figures Task, the Iowa Gambling Task, the Wisconsin Card Sorting Test, the Tower of London test, and the Continuous Performance Test – demonstrated less impulsivity in gambling behavior. The differences in performance between pathological gamblers and healthy controls on the neurocognitive tasks could be due to addictive behavior features rather than impulsive behavior.

Background: Fetal alcohol spectrum disorder is a range of disabilities caused by gestational exposure to alcohol. FASD[1] is the leading cause of preventable mental retardation and developmental disability in the United States, with an incidence of 1–10 per 1000 live births. FASD in Israel has yet to be examined systematically.

Objectives: To evaluate professionals’ experience, awareness and knowledge of FASD in Israel and their awareness of maternal consumption of alcohol, and to collect epidemiological data on the syndrome in Israel.

Methods: A short questionnaire was sent to all 43 program directors of genetic institutes (n=14) and child developmental centers in Israel (n=29). Four questions related to their experience and knowledge of FASD. The epidemiological survey included data from all 17 hospitals in Israel and from the two main health management organizations within the public health care system.

Results: The response rate was 98% (n=42). A total of 38.1% of respondents reported having diagnosed at least one case of FASD and fewer than 10% of respondents stated that the knowledge regarding FASD among physicians in Israel was adequate. Developmental pediatricians were more likely to have diagnosed at least one case as compared to geneticists. During the period 1998–2007 the diagnosis of FASD appeared in the records of only 4 patients from the total number of 17 hospitals in Israel. During the same period only six patients were diagnosed at the HMO[2] within the public health care system.

Conclusions: Despite the accumulated knowledge on FASD in many countries and the increase in alcohol consumption in Israel, professionals' awareness of its potential damage is limited. Educational programs to increase physician awareness should accompany publicity campaigns warning the public of the dangers associated with alcohol consumption during pregnancy.

Background: The internet has transformed the patient-physician relationship by empowering patients with information. Because physicians are no longer the primary gatekeepers of medical information, shared decision making is now emerging as the hallmark of the patient-physician relationship.

Objectives: To assess the reactions of primary care physicians to encounters in which patients present information obtained from the internet (e-patients) and to examine the influence of the physicians' personal and demographic characteristics on their degree of satisfaction with e-patients.

Methods: A questionnaire was developed to assess physician attitudes to e-patients, their knowledge and utilization of the internet, and their personal and professional characteristics. Family physicians in central Israel were interviewed by telephone and in person at a continuing medical education course.

Results: Of the 100 physicians contacted by phone, 93 responded to the telephone interviews and 50 physicians responded to the questionnaire in person. There was an 85% response rate. The mean age of respondents was 49 years. Most physicians were born in Israel, with a mean seniority of 22 years. Most had graduated in Eastern Europe, were not board certified and were employees of one of the four health management organizations in Israel. Most physicians responded positively when data from the internet were presented to them by patients (81%). A number of respondents expressed discomfort in such situations (23%). No association was found between physician satisfaction in relationships with patients and comfort with data from the internet presented by patients.

Conclusions: Physicians in this sample responded favorably to patients bringing information obtained online to the consultation. Though it may be difficult to generalize findings from a convenience sample, Israeli family physicians appear to have accepted internet use by patients.

Isolated ventricular non-compaction is a frequently underdiagnosed rare congenital cardiomyopathy. The importance of diagnosing this cardiomyopathy lies especially in asymptomatic patients, screening relatives of index cases in order to focus on their follow-up and searching for criteria warranting prophylactic anticoagulation, implantable cardioverter defibrillator and anti-remodeling drugs such as angiotensin-converting inhibitors. We present the clinical and imaging characteristics of this entity and discuss some of the therapeutic dilemmas involving these patients.
 

Background: Although unprotected left main coronary artery disease is considered by contemporary guidelines to be an indication for surgery, percutaneous coronary intervention may be necessary in patients at high surgical risk.

Objectives: To assess the outcome of angioplasty in the treatment of unprotected LMCA[1] disease.

Methods: Angiographic and clinical data were collected prospectively for all patients who underwent emergent or non-emergent (planned) therapeutic PCI[2] for unprotected LMCA disease at our center from 2003 to 2007. Baseline values were compared with findings at 1, 6 and 12 months after the procedure.

Results: The study group comprised 71 consecutive patients with a mean age of 74 ± 12 years; 63% were men, and 31% had diabetes. Forty-three patients had a planned procedure and 28 an emergent procedure. Mean EuroScore was 7.3 ± 3.6 (range 5–12). Forty-nine percent of the procedures were performed with bare metal stents and 51% with drug-eluting stents. Procedural success was achieved in 100% of cases. The overall mortality rate was 11.3% at 1 month, 18.3% at 6 months and 19.7% at 12 months. Elective PCI was associated with significantly lower mortality (2.3% vs. 25% at 1 month, 4.6% vs. 39% at 6 months and 6.9% vs. 39% at 12 months), and the use of drug-eluting stents was associated with lower rates of target vessel revascularization and major adverse cardiac events than use of bare metal stents (2.8% vs. 14% at 1 month, 8.3% vs. 43% at 6 and 12 months). Variables that correlated with increased mortality or MACE[3] at 6 and 12 months were cardiogenic shock, emergent PCI, ejection fraction < 35%, renal failure, distal left main stenosis location, and reference diameter < 3 mm.

Conclusions: PCI is a feasible and relatively safe therapeutic option for unprotected LMCA. The less favorable outcome of emergent compared to planned PCI is probably attributable to the overwhelming acute myocardial ischemic injury in emergent cases. The use of drug-eluting stents may improve the intermediate-term restenosis rate.

Background: Mite allergy is an indoor allergen responsible for most respiratory allergies in the western world. Environmental control can modify disease activity in these patients.

Objectives: To examine the benefit of the Plasma Cluster^® device (Sharp, Japan) for inactivating and removing mites from the environment of patients diagnosed with either mite‑sensitive perennial allergic rhinitis or mite‑sensitive allergic asthma.

Methods: Patients with AR[1] (n=30) or AA[2] (n=10) were enrolled into a prospective open observational 8 week study. The first 2 weeks involved initial evaluation, the following 4 weeks consisted of active usage of the device, and the last 2 weeks were designated for follow‑up. Symptom scores (recorded daily by patients and during visits by physicians) were recorded and analyzed.

Results: Patients with AR experienced a significant (P < 0.05) reduction in nasal discharge, post‑nasal drip, nasal congestion, nasal itching, watery eyes, itchy eyes, headache, itchy ears, night disturbances and an improvement in general well‑being during the last 2 days of the study compared to baseline. Patients with AA reported significant (P < 0.05) reduction in dyspnea, wheezing and the need to avoid dust mites. There was a significant (P < 0.05) improvement in mean peak expiratory flow rate at study closure compared to baseline.

Conclusions: Short-term usage of the Plasma Cluster^® device resulted in considerable clinical improvement and increased peak expiratory flow rate in patients with AR or AA. The findings of this pilot study warrant longer and controlled studies to determine the value of this device in the treatment of various allergic disorders.
