Background: In compliance with public health measures initiated by the Israel Ministry of Health following an outbreak of influenza, amantadine was administered to all patients in the psychogeriatric department of Lev Hasharon Mental Health Center to reduce transmission and illness severity in this susceptible population.

Objectives: To evaluate the potential beneficial effects of amantadine on elderly hospitalized patients with persistent schizophrenia.

Methods: We conducted a retrospective case review of the treatment effects of amantadine on the mental, cognitive and clinical states of elderly chronic schizophrenic patients who received concomitant amantadine treatment and were routinely evaluated with the Positive and Negative Syndrome Scale, the Mini Mental State Examination, and Sandoz Clinical Assessment Geriatric Scale.

Results: No significant differences before and after amantadine treatment were noted. Conclusion: Amantadine did not influence the mental, cognitive and clinical states of elderly schizophrenia patients and thus can be considered as an anti-influenza preventive measure for this population, when indicated.

survey. A tailor-made CME program may have contributed to the improvement in skills and quality of care.

Background: Enteral nutrition in the critically ill patient is often complicated by gastrointestinal intolerance, manifested by a large gastric residual volume. The frequency of GRV[1] assessment and the intolerant level above which feeding is stopped is controversial.

Objectives: To evaluate a novel approach to EN[2] by allowing high GRV and once-daily assessment that was correlated with the paracetamol absorption test.

Methods: We conducted a pilot prospective study in an 18 bed general intensive care unit. The study group comprised 52 consecutive critically ill mechanically ventilated patients. Enteral nutrition was started at full delivery rate. Once-daily assessment of GRV with three consecutively repeated threshold volumes of 500 ml was performed before stopping EN. The paracetamol absorption test was performed and correlated to GRV. Patients were divided into two groups: low GRV (< 500 ml), and high GRV (at least one measurement of GRV > 500 ml). Clinical outcome included maximal calories delivered, incidence of pneumonia, ICU[3] length of stay, and ICU and hospital mortality.

Results: There were 4 patients (9.5%) with ventilator-associated pneumonia in the low GRV group and 3 (30%) in the high GRV group (P = 0.12). GRV was inversely correlated to paracetamol absorption; however, neither GRV nor paracetamol absorption was associated with the development of pneumonia. Both groups had similar ICU length of stay (11.0 ± 8.2 vs. 13.8 ± 14.4 days, P = 0.41), and similar ICU (21% vs. 40%, P = 0.24) and hospital mortality (35% vs. 40%, P = 1.0).

Conclusions: In critically ill mechanically ventilated patients, allowing larger gastric residual volumes, measured once daily, enables enteral feeding with fewer interruptions which results in high calorie intake without significant complications or side effects.

Background: The prevalence of Parkinson's disease varies among ethnic and geographic groups around the world, being very low in China and high in Argentina. While the main etiology of the disease has yet to be determined, environmental, occupational and genetic factors seem to play important roles.

Objectives: To estimate the prevalence of PD in an Arab Muslim population in Israel, using the drug tracer approach.

Methods: We studied a Muslim Arab population living in a well-defined geographic area in Israel, with the majority located in two towns and two large villages. Of the approximately 115,000 residents, about 38% are under the age of 15 and 7.75% are older than 65. Drug tracer methodology was applied in this study. All those who were on anti-PD[1] medication were identified and examined by a neurologist to confirm the diagnosis.

Results: The overall crude prevalence of PD in this population was low, 43.24/100,000, while the prevalence in the age group above 65 years was 477.32/100,000. Below this age, the prevalence was very low, 12.29/100,000. PD prevalence was higher in males than in females (ratio 1.17); 63% of male patients smoked cigarettes. The prevalence was found to be twice as high among the residents of rural areas, where most inhabitants work in agriculture.

Conclusions: The prevalence of PD among the Arab population in Israel is considered low and comparable to that reported in other Arab countries.

Background: Children report various types of fear in the context of hospitalization, such as fear of separation from the family, having injections and blood tests, having to stay in the hospital for a long time, and being told “bad news” about their health.

Objectives: To examine the effects of the “Teddy Bear Hospital” method on preschool children’s fear of future hospitalization.

Methods: The study group comprised 41 preschool children aged 3–6.5 years (mean 5.1 ± 0.7 years), and 50 preschool children, age matched and from a similar residential area, served as the control group. Assessment included a simple one-item visual analog scale of anxiety about hospitalization. This was assessed individually one day prior to the intervention and again a week after the intervention in both groups

Results: While baseline levels of anxiety were not different between groups [t(89) = .4, NS], children in the “Teddy Bear Hospital” group reported significantly lower levels of anxiety than the control group at follow-up

Conclusions: Our results indicate that by initiating a controlled pain-free encounter with the medical environment in the form of a “Teddy Bear Hospital,” we can reduce children’s anxiety about hospitalization.

Background: Magnetic resonance imaging is a diagnostic tool of growing importance. Since its introduction, certain medical implants, e.g., pacemakers, were considered an absolute contraindication, mainly due to the presence of ferromagnetic components and the potential for electromagnetic interference. Patients with such implants were therefore prevented from entering MRI systems and not studied by this modality. These devices are now smaller and have improved electromechanical interference protection. Recently in vitro and in vivo data showed that these devices may be scanned safely in the MRI.

Objectives: To report our initial experience with three patients with pacemakers who underwent cerebral MRI studies.

Methods: The study included patients with clear clinical indications for MRI examination and who had implanted devices shown to be safe by in vitro and in vivo animal testing. In each patient the pacemaker was programmed to pacing-off. During the scan, continuous electrocardiographic telemetry, breathing rate, pulse oximetry and symptoms were monitored. Specific absorption rate was limited to 4.0 W/kg for all sequences. Device parameters were assessed before, immediately after MRI, and 1 week later.

Results: None of the patients was pacemaker dependent. During the MRI study, no device movement was felt by the patients and no episodes of inappropriate inhibition or rapid activation of pacing were observed during the scan. At device interrogation here were no significant differences in device parameters pre-, post-, and 1 week after MRI. Image quality was unremarkable in all imaging sequences used and was not influenced by the presence of the pacemaker.

Conclusion: Given appropriate precautions, MRI can be safely performed in patients with a selected permanent pacemaker. This may have significant implications for current MRI contraindications.  

Background: Patient feedback is increasingly being used to assess the quality of healthcare.

Objective: To identify modifiable independent determinants of patient dissatisfaction with hospital emergency care.

Methods: The study group comprised a random sample of 3,152 of the 65,966 adult Israeli citizens discharged during November 1999 from emergency departments in 17 of the 32 acute care hospitals in Israel. A total of 2,543 (81%) responded to a telephone survey tht used a structured questionnaire. The ndependent variables included: hospital characteristics, patient demographic variables, patient perception of care, self-rated health status, problem severity, and outcome of care. The dependent variable was dissatisfaction with overall ED[1] experience on a 1–5 Likert-type scale dichotomized into not satisfied (4 and 5) and satisfied (1,2 and 3).

Results: Eleven percent of the population reported being dissatisfied with their emergency room visit. Univariate analyses revealed that dissatisfaction was significantly related to ethnic group, patient education, hospital identity and geographic location, perceived comfort of ED facilities, registration expediency, waiting times, perceived competence and attitudes of caregivers, explanations provided, self-rated health status, and resolution of the problem that led to referral to the ED. Multivariate analyses using logistic regressions indicated that the four most powerful predictors of dissatisfaction were patient perception of doctor competence and attitudes, outcomes of care, ethnicity, and self-rated health status.

Conclusions: Attempts to reduce dissatisfaction with emergency care should focus on caregiver conduct and attitudes. It may also be useful to improve caregiver communication skills, specifically with ethnic minorities and with patients who rate their health status as poor.
