Background: Locally delivered steroids by inhalers or nebulizers have been shown in small trials to be effective in acute asthma attack, but evidence-based data are insufficient to establish their place as routine management of adult asthma attacks.

Objectives: To determine the efficacy of nebulized compared to systemic steroids in adult asthmatics admitted to the emergency department following an acute attack.

Methods: Adult asthmatics admitted to the ED[1] were assigned in random consecutive case fashion to one of three protocol groups: group 1 – nebulized steroid fluticasone (Flixotide Nebules®), group 2 – intravenous methylprednisolone, group 3 – combined treatment by both routes. Objective and subjective parameters, such as peak expiratory flow, oxygen saturation, heart rate, and dyspnea score, were registered before and 2 hours after ED treatment was initiated. Steroids were continued for 1 week following the ED visit according to the protocol arm. Data on hospital admission/discharge rate, ED readmissions in the week after enrollment and other major events related to asthma were registered.

Results: Altogether, 73 adult asthmatics were assigned to receive treatment: 24 patients in group 1, 23 in group 2 and 26 in group 3. Mean age was 44.4 ± 16.8 years (range 17–75 years). Peak expiratory flow and dyspnea score significantly improved in group 1 patients compared with patients in the other groups after 2 hours of ED treatment (P = 0.021 and 0.009, respectively). The discharge rate after ED treatment was significantly higher in groups 1 and 3 than in group 2 (P = 0.05). All 73 patients were alive a week after enrollment. Five patients (20.8%) in the Flixotide treatment arm were hospitalized and required additional systemic steroids. Multivariate analysis of factors affecting hospitalization rate demonstrated that severity of asthma (odds ratio 8.11) and group 2 (OD[2] 4.17) had a negative effect, whereas adherence to chronic anti-asthma therapy (OD 0.49) reduced the hospitalization rate.

Conclusions: Our study cohort showed the advantage of nebulized steroid fluticasone versus systemic corticosteroids in adult asthmatics managed in the ED following an acute attack. Both these and previous results suggest that nebulized steroids should be used, either alone or in combination with systemic steroids, to treat adults with an acute asthma attack.

Background: The frequency of colorectal cancer screening tests in Israel is poor, and is much lower than in the United States. This low rate has been attributed to health system failures as well as to barriers on the part of both physicians and patients.

Objectives: To further identify particular health system failures, physician and patient-based barriers, and the effectiveness of public lectures in improving the frequency of performance of CRC[1] screening tests.

Methods: Public lectures on colorectal cancer prevention were held. A gastroenterologist presented the lectures, which were followed immediately by a questionnaire and 4 months later by a telephone call.

Results: Of the 80% of attendees who had never undergone any CRC screening test, only 18% reported family physician recommendations for such tests. Eighty-four percent reported willingness to undergo fecal occult blood testing and 52% to undergo colonoscopy; 62% replied that they should undergo some CRC screening test and 90% believed that these tests save lives. Of the women, 47% expressed preference for a female gastroenterologist. Follow-up showed that 34% proceeded to undergo some CRC screening test: 60% chose colonoscopy and 40% FOBT[2].

Conclusions: Public lectures are effective at improving compliance with the CRC screening test. Physicians should recommend these tests to appropriate individuals. Same-gender gastroenterologists should be considered for individuals uneasy about someone from the opposite gender performing the test. Assessing the various health-promotion efforts can direct us in implementing finite resources to greatest effect. Local cancer institutes and societies may be supportive in disseminating screening information in this way.

Background: The Beer Sheva Psoriasis Severity Score is a novel instrument for the assessment of psoriasis severity, designed for use in routine clinical conditions.

Objective: To identify the main factors of the BPSS[1].

Methods: The sample used to study the BPSS comprised 70 patients with psoriasis vulgaris treated by climatotherapy at the Dead Sea. Psoriasis severity was assessed using BPSS and PASI (Psoriasis Area and Severity Index). Factor analysis was used to identify the main factors of BPSS. Internal consistency analysis was performed. Correlation matrices were generated to compare BPSS factors.

Results: Factor analysis demonstrated that BPSS included six factors that explained 74.0% of the variance as follows: patient assessment 26.0%; physician assessment 13.2%; palms and soles involvement 11.9%; genitals, nails, and pruritus 9.0%; face involvement 7.3%; and scalp involvement 6.6%. Total scale Cronbach’s alpha was 0.76; alpha for the factors ranged between 0.39 and 0.81.

Conclusion: The major factors of BPSS were identified. BPSS may be used as a comprehensive tool for measuring psoriasis severity.

Background: The crowded environment of correctional facilities may enhance infectious diseases transmission, such as tuberculosis.

Objectives: To define the tuberculosis burden in prisons in Israel, a country of low TB[1] incidence (7.9 cases:100,000 population in 2004), in which about 13,000 inmates are being incarcerated annually, and to recommend policy adaptations for TB control.

Methods: All prison clinic lung records from 1998 through 2004 in Israel were reviewed to identify pulmonary TB patients. Additionally, we reviewed TB epidemiological investigation files from one northern prison (years 2002 through 2005) to evaluate possible transmission of the disease.

Results: During the study period 23 Israeli inmates had pulmonary TB (25 cases/100,000 prisoners), which was 3.5 times higher than for the general population. Of those, 18 (78%) were born in the Former Soviet Union and immigrated to Israel after 1990. Four pulmonary TB cases in the evaluated prison were reported, and 22% (149/670) of all inmates and staff were referred for treatment of latent TB infection.

Conclusions: To prevent future TB cases, we recommend new prevention measures, including a symptom questionnaire for all new inmates and selective tuberculin skin testing for inmates infected with human immunodeficiency virus/AIDS, those who inject drugs, and those who emigrated from the former Soviet Union after 1990. New staff should be screened by the two-step tuberculin skin test and annual symptoms questionnaire thereafter. Incarceration may be used as a point of detection for TB and a window of opportunity for treatment in this hard-to-reach population. 

Background: Percutaneous tracheostomy has largely replaced surgical tracheostomy in the intensive care unit setting. Although it seems logical that surgeons continue to do tracheostomies, anesthesiologists and intensive care specialists are familiar with airway control and guide wire techniques and could replace surgeons in the performance of PDT.

Objectives: To assess the safety and effectiveness of bedside PDT[1] in the ICU[2].

Methods: We conducted a retrospective chart review of 207 patients in the ICU who underwent PDT by an intensive care physician.

Results: Subcutaneous emphysema without pneumothorax occurred in one patient. Four patients underwent surgical revision following PDT. Early bleeding (during the first 48 hours following the procedure) was the indication in two patients and late bleeding, on the 10th post-PDT day, in one. In one case PDT was converted to surgical tracheostomy due to inadvertent early decannulation. There was one death directly related to the procedure, due to an unrecognized paratracheal insertion of the tracheostomy tube followed by mechanical ventilation, which led to bilateral pneumothorax, pneumomediastinum and cardio-circulatory collapse. No infectious complications were seen at the stoma site or surrounding tissues.

Conclusions: PDT by intensive care physicians appears to be safe and should be included in the curriculum of intensive care residency.

Background: Until three decades ago coronary heart disease and stroke were considered rare in the Israeli Bedouin population. Today, this population shows increasing high prevalence compared to the Jewish population.

Objectives: To evaluate the prevalence of diagnosed cardiovascular risk factors among the Bedouin (hypertension, diabetes mellitus, dyslipidemia), and to assess compliance with follow-up tests and drug treatment.

Methods: The study included all listed patients aged 20 years and older in eight clinics in major Bedouin towns, and in two large teaching clinics in Beer Sheva (Jewish population). Risk factor data were extracted from the clinics' computerized databases. For those diagnosed with hypertension, diabetes or dyslipidemia, drug purchasing data were collected from the pharmacy database to determine compliance with treatment, and from the central laboratory mainframe (HbA1c and low density lipoprotein-cholesterol) to evaluate follow-up and control.

Results: A significantly higher prevalence of diabetes in all age groups was found in the Bedouin population compared to the Jewish population; age-adjusted results show a prevalence of 12% vs. 8% respectively (P < 0.001). The prevalence of dyslipidemia and age-adjusted hypertension was lower among Bedouins (5.8% vs. 18.2%, P < 0.01 and 17% vs. 21%, P < 0.001 respectively). Two-thirds of hypertensive Bedouin patients and 72.9% of diabetic Bedouin patients were not compliant with treatment. For dyslipidemia only 10.4% of the Bedouins were compliant compared with 28.2% in the Jewish population (P < 0.001).

Conclusions: Compliance with drug therapy and follow-up tests was found to be a major problem in the Bedouin population.
 

Background: Patients with severe persistent asthma despite GINA 2002 step 4 treatment are at risk for asthma-related morbidity and mortality. This study constitutes the Israeli arm of the international INNOVATE study.

Objectives: To determine the efficacy and safety of Xolair® as an add-on treatment in patients with severe persistent asthma.

Methods: Asthma patients (age 12–75 years) not controlled with high dose inhaled corticosteroids and long-active beta-2 agonists were randomized to receive either Xolair® or placebo for 28 weeks in a double-blind study in two Israeli centers.

Results: Thirty-three patients, 20 females and 13 males, mean age 54 ± 11.7 years, were included in the Israeli arm of the INNOVATE study. There were neither major adverse events nor withdrawals from the study. Xolair® (omalizumab) significantly reduced the rate of clinically significant asthma exacerbations (55% reduction) and all asthma-related emergency visits (53% reduction).
Conclusions: In patients with severe persistent difficult-to-treat asthma, despite regular treatment with LABA[1] and inhaled corticosteroids (GINA 2002 step 4), Xolair® is a safe and effective treatment

Background: Asthma control and treatment compliance are widely investigated issues around the world. Studies have demonstrated relatively low asthma compliance and control in 40–90% of asthma patients in different countries. There are no available data on the Israeli adult asthmatic population

Objectives: To investigate the level of asthma control and compliance in adult asthmatic patients.

Methods: This cross-sectional study of consecutive adult asthmatic patients visiting the pulmonary clinic used a combined questionnaire that included demographics, data on asthma severity and management, and asthma control and compliance scores. Each patient was interviewed and questionnaires were filled out during a routine visit.

Results: The study group comprised 142 males (35.4%) and 259 females (64.6%). Compliance was found optimal in 8 patients (2%), fair in 146 (36%), partial in 156 (39%) and poor in 92 (23%) of the participating asthmatic patients. Asthma control was found optimal in 26 (7%), fair in 124 (31%), partial in 122 (30%) and poor in 129 (32%) patients. Sephardic and Ashkenazi Jewish origin, higher level of education, and treatment protocol including either single fixed-dose inhalers or short-acting beta-agonist bronchodilators significantly improved compliance in our cohort. Socioeconomic status and compliance were found to positively affect asthma control, whereas active smoking negatively affected asthma control in the study patients.

Conclusions: The figures of optimal asthma control and compliance to treatment in Israeli adult asthmatics are low and worse than reported in other studies abroad.
 

Backgound: The use of intraoperative transesophageal echocardiogram in patients with infective endocarditis is usually reserved for cases of inadequate preoperative testing or suspected extension to perivalvular tissue.

Objectives: To explore the impact of routine intraoperative TEE[1] in patients with infective endocarditis.

Methods: The impact of intraoperative TEE on the operative plan, anatomic-physiologic results, and hemodynamic assessment or de-airing was analyzed in 59 patients (38 males, 21 females, mean age 57.7 ± 16.8 years, range 20–82) operated for active infective endocarditis over 56 months.

Results: Immediate pre-pump echocardiography was available in 52 operations (86.7%), and changed the operative plan in 6 of them (11.5%). Immediate post-pump study was available in 59 patients (98.3%) and accounted for second pump-run in 6 (10.2%): perivalvular leak (3 cases), and immobilized leaflet, significant mitral regurgitation following vegetectomy, and failing right ventricle requiring addition of vein graft (1 case each). Prolonged de-airing was necessary in 6 patients (10.2%). In 5 patients (8.5%) the postoperative study aided in the evaluation and treatment of difficult weaning from the cardiopulmonary bypass pump. In 21 patients (35.6%) the application of intraoperative TEE affected at least one of the four pre-specified parameters.
Conclusions: Intraoperative TEE has an important role in surgery for infective endocarditis and should be routinely implemented
