Background: The prevalence of morbid obesity is increasing rapidly. Weight reduction is very difficult using diet restriction and physical activity alone. Sibutramine has been shown to be effective and safe as an adjuvant therapy to diet restrictions.

Objectives: To describe our experience using sibutramine in weight reduction treatment of adolescents suffering from morbid obesity.

Methods: The study group comprised 20 young persons (13 females, mean age 15 years 4 months, range 13–18 years) with morbid obesity (body mass index over the 95th percentile for age and/or ≥ 30 kg/m²) were treated with sibutramine 10 mg once a day for 1 year.

Results: Mean BMI[1] was 40 ± 5.6 kg/m² (range 30.1–49.5 kg/m²) at the beginning of treatment. Most patients showed an early weight reduction to mean BMI 39.3 ± 4.9 and 35.9 ± 5.7 at 3 and 6 months respectively, but stopped losing weight over the next 6 months. During the follow-up period 17 patients discontinued the treatment. The main reason for dropout was the slow rate of weight reduction after 6 months. Patients suffering from concomitant disorders (severe asthma, hypertension, sleep obstructive apnea) showed improvement after weight reduction. Adverse reactions from the treatment were transient, mild and well tolerated.

Conclusions: Sibutramine may help in achieving weight reduction for a short period and in improving concomitant health problems, however its long-term effect is limited.

"Surviving severe injury depends very heavily upon the time it takes to receive trauma services. The risk of death increases three fold after one hour without the uniqe surgical care of a trauma center. This is often referred to as the 'golden hour'..."

Amyloidosis is characterized by the extra-cellular deposition of abnormal insoluble fibrillar proteins in organs and tissues.

Background: There are no national data on the burden and management of acute cerebrovascular disease in Israel.

Objectives: To delineate the burden, characteristics, management and outcomes of hospitalized patients with acute cerebrovascular disease in Israel, and to examine adherence to current guidelines.

Methods: We prospectively performed a national survey in all 28 hospitals in Israel admitting patients with acute cerebrovascular events (stroke or transient ischemic attacks) during February and March 2004.

Results: During the survey period 2,174 patients were admitted with acute cerebrovascular disease (mean age 71 ± 13 years, 47% women; 89% ischemic stroke or TIA[1], 7% intracerebral hemorrhage and 4% undetermined stroke). Sixty-two percent of patients were admitted to departments of Medicine and a third to Neurology, of which only 7% were admitted to departments with a designated stroke unit. Head computed tomography was performed during hospitalization in 93% of patients. The overall rate of urgent thrombolytic therapy for acute ischemic stroke was 0.5%. Among patients with ischemic stroke or TIA, 94% were prescribed an antithrombotic medication at hospital discharge, and among those with atrial fibrillation about half were prescribed warfarin. Carotid duplex was performed in 30% and any vascular imaging study in 36% of patients with ischemic events. The mean length of hospital stay was 12 ± 27 days for ICH[2] and 8 ± 11 days for ischemic stroke. Among patients with ICH, 28% died and 66% died or had severe disability at hospital discharge, and for ischemic stroke the corresponding rates were 7% and 41% respectively. Mortality rates within 3 months were 34% for ICH and 14% for ischemic stroke.

Conclusions: This national survey demonstrates the high burden of acute stroke in Israel and reveals discordance between existing guidelines and current practice. The findings highlight important areas for which reorganization is imperative for patients afflicted with acute stroke.

Background: In Japan, helicopters have rarely been used for emergency medical services. The use of helicopters not only ensures rapid evacuation but may also serve to provide emergency management to patients with life-threatening injuries in the prehospital setting.

Objectives: To evaluate a Japanese helicopter-based emergency medical system including an onboard physician, particularly in terms of probability of survival.

Methods: We conducted a retrospective review of trauma victims, and calculated two estimates of PS[1] – at the scene and on arrival at the emergency department – based on patient age, Injury Severity Score, and Revised Trauma Score.

Results: We identified trauma victims who had an ISS[2] above 15 and were transported from the scene by helicopter. Excluding cardiopulmonary arrest at the scene, 151 cases were studied. Thirty-two patients had hemodynamic instability with systolic blood pressures below 90 mmHg, caused by hemorrhagic shock (29 cases) or obstructive shock (3 cases). Their PS values were 0.56 ± 0.38 in the prehospital setting and 0.65 ± 0.38 on arrival at the ED[3], representing a significant difference (P = 0.0003). Twenty-four of these patients survived, reflecting successful resuscitation during prehospital and ED management.

Conclusions: A doctor-helicopter system was shown to improve probability of survival for life-threatening trauma in the Japanese emergency medical system.

Background: In the last decade there has been an increase in asthma morbidity. Hospital admission rates for childhood asthma are influenced by the prevalence of asthma and the quality of asthma care.

Objective: To assess trends in hospital admission and readmission rates for childhood asthma in the Jezreel Valley in Israel in the last decade, and to evaluate the possible effect of changes in asthma treatment upon hospitalization for acute asthma during this period.

Methods: All records from pediatric patients from the central hospital in the Jezreel Valley in northeastern Israel over a 10 year period from 1990 through 1999 who were diagnosed as having asthma were thoroughly reviewed and analyzed for admissions, re-admissions, and treatment before and during admissions

Results: There were 1584 admissions, 1208 were first-time admissions and 374 were re-admissions. The number of first-time admissions increased significantly over time (P < 0.0001), with a significant decrease of re-admissions (P < 0.005); this finding was more significant in children under the age of 8 years (P < 0.005). The length of hospital stay decreased significantly from 3.3 days to 2.7 days (P < 0.002). Significant changes in the use of medications included an increase in inhalant glucocorticoids and a decrease in the use of sodium cromoglycate and theophylline. Controller medication use was concomitant with a significant decrease in the re-admission rates.

Conclusions: The increase in the admission rate and the decrease in the rate of re-admissions and the length of hospital stay probably reflect the increase in the prevalence of asthma and changes in its treatment, respectively. It is essential that asthma be recognized as a significant cause of morbidity and that controller medications be administered to decrease the asthma's severity, morbidity, and resultant hospital admissions.
 

Objectives: To determine the effectiveness of a neuroreflexology-based screening test, specifically the Medex device (Medex Screen Ltd.), for diagnosing patients undergoing conventional internal organ assessment, in a hospital setting.

Methods: Patients admitted to an internal medicine department, who met the inclusion criteria and agreed to participate, underwent conventional medical evaluation that included past medical history and physical examination. Another examination was conducted by a second physician using the Medex device to determine internal organ pathologies. A third researcher compared the actual “conventional” diagnosis with the Medex device output using standard statistical analysis.   

Results: Overall, 150 patients participated in the study. Correlation was significant for all categories (P < 0.01) except for blood and lymphatic disease. A high sensitivity (>70%) was measured for cardiovascular, respiratory, gastrointestinal and genitourinary diseases. The highest measure of agreement, as represented by the Cohen-Kappa factor, was found for respiratory disease (0.57).

Conclusions: Although the exact mechanism is not entirely clear, measurement of electroskin impedance of dermal-visceral zones has the potential to serve as a screening tool for inner organ pathologies. Further research should be conducted to create more evidence to support or dispute the use of this technique as a reliable diagnostic tool.

Objectives: To describe the sociodemographic, medical and functional characteristics of people aged 80–90 and 90+ who were admitted to a sub-acute geriatric hospital and to compare the hospitalization outcomes between these subgroups.

Methods: We compared the demographic and clinical data (extracted by means of chart review) of two groups of elderly who were admitted to the Reuth Medical Center during 2001–2002: those aged 90+ and those 80–89. Among survivors, the main outcome measures at discharge were mortality rate, functional ability, and place of residence.

Results: The study included 108 patients who were admitted to different divisions of Reuth: 55 patients aged 90+ and 53 aged 80–90. The mortality rate was significantly elevated in the older age group (49.1% vs. 28.1% in the younger age group) on multivariate analysis. The most important prognostic factors for mortality were incontinence (odds ratio 3.45) and being dependent before admission (OR[1] 4.76). Among survivors an association was found between being incontinent and dependent before hospitalization, and being dependent on discharge.

Conclusions: The main prognostic factors for mortality and functional outcome in patients admitted to a non-acute geriatric hospital are incontinence and functional state prior to admission, and not age per se.

Objectives: To assess the achievements of participants in the PALS[1] course, as a cohort and by professional group, and their evaluations of different aspects of the course; and to describe the educational modifications introduced to the course since its introduction in Israel on the basis of our teaching experience.

Methods: The study sample consisted of physicians, nurses and paramedics from all areas of Israel who registered for PALS between January 2001 and December 2003. Participants took a standardized test before and after the course; a score of 80 or higher was considered a pass. On completion of the course, participants were requested to complete a 24-item questionnaire evaluating the quality of the course as a whole, as well as the lectures, skill stations, and instructors’ performance. Items were rated on a 5-point scale. Results were analyzed using the BMPD statistical package.

Results: Altogether, 739 subjects participated in 28 courses: 13 attending (in-hospital) physicians (1.8%), 89 community pediatricians (12%), 124 residents (16.8%), 304 nurses (41.1%), and 209 paramedics (28.3%). About half (48.9%) were hospital-based, and about half (47.9%) had no experience in emergency medicine. A passing grade was achieved by 89.4% of the participants; the mean grade for the whole sample was 87.2%. The mean test score of the residents was significantly better than that of the nurses (P < 0.05) and pediatricians (P < 0.01). The median evaluation score for four of the five stations was 5, and the mean overall score for all items was  4.56 (range by item 3.93–4.78).

Conclusions: PALS was successfully delivered to a large number of healthcare providers in various professional groups with very good overall achievements and high participant satisfaction. It significantly increased participants’ knowledge of pediatric resuscitation. We therefore recommend the PALS course as an educational tool in Israel.
