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: The epidemiology of bacteremic febrile neutropenia differs between locations and constitutes the basis for selection of empiric antibiotic therapy for febrile neutropenia.

Objectives: To describe the epidemiology of bacteremia among patients with neutropenia in a single center in Israel.

Methods: We conducted a prospective data collection on all patients with neutropenia (< 500/mm³) and clinically significant bacteremia or fungemia during the period 1988–2004.

Results: Among adults (462 episodes) the most common bloodstream isolate was Esherichia coli. Gram-negative bacteria predominated throughout the study period and the ratio between Gram-negative and Gram-positive bacteremia increased from 1.7 to 2.3 throughout the study period. Among children (752 episodes), the ratio between Gram-negative and Gram-positive bacteremia reversed from 1.2 to 0.7, due to increasing prevalence of coagulase-negative staphylcoccal bacteremia. Both among adults and children, the length of hospital stay prior to bacteremia had a major impact on the pathogens causing bacteremia and their antibiotic susceptibilities. The prevalence of E. coli decreased with time in hospital, while the rates of Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterobacter spp., Acinetobacter spp., Enterococcus spp. and Candida spp. increased. Resistance to broad-spectrum empiric monotherapy in our center was observed in > 40% of Gram-negative bacteria when bacteremia was acquired after 14 days in hospital.
Conclusions: Improved infection-control measures for neutropenic cancer patients in our center are needed. Empiric antibiotic treatment should be tailored to patients’ risk for multidrug-resistant organisms. Individual hospitals should monitor infection epidemiology among cancer patients to guide empiric antibiotic treatment

Ludwik Zamenhof (1859-1917) lived in Poland under Russian and later German rule. He invented and propagated Esperanto – an artificial, easy-to-learn language. Literally meaning “language of hope,” Esperanto was constructed to avoid misunderstandings, establish communication and facilitate harmony among different nationalities. Simply, he wanted people to accept one another despite observed differences. He was a skilled ophthalmologist, but figuratively, he wished to heal the eyes of humankind to look without hate, just as the biblical Tobias removed the cataract from the corners of his father’s eyes to restore his sight.

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.
 

Background: Numerous studies have shown an association between asthma and mental disorders. While elevated rates of asthma have been noted among psychiatric patients with anxiety disorders and post-traumatic stress disorder, several studies have found elevated rates of mental disorders among asthma patients. Such studies, however, have generally relied upon questionnaires and assessment by non-specialist physicians to diagnose mental disorders and asthma.

Objectives: To examine a possible association between asthma and psychiatric diagnoses in Israeli military recruits and soldiers.

Methods: In this cross-sectional study we compared the prevalence of mental diagnoses in asthmatic recruits and soldiers to that in non-asthmatic recruits and soldiers. A total of 195,903 recruits and soldiers were examined by Israel Defense Forces recruiting offices and fitness boards. Diagnoses of asthma were based on a pulmonologist's diagnosis, including spirometry at rest and exercise testing as indicated; diagnoses of mental disorders were based on examination by a psychiatrist.

Results: The prevalence of asthma was found to be 7.8% (current) and 9.8% (lifetime). The prevalence of mental disorders was 13.4%. Current asthma was associated with an increased likelihood of any mental disorder (OR = 1.20, 95% CI = 1.15–1.26), and specifically with mood and anxiety disorders (1.31, 1.19–1.46), introvert personality disorders (1.20, 95% 1.12–1.28) and adjustment disorder (1.43, 1.26–1.62). Lifetime asthma was associated with an increased likelihood of the same disorders, but the association was not as powerful.

Conclusions: The results validate the previously documented association between asthma and mental disorders, using a sample of unprecedented size and improved methodology. A multidisciplinary approach to asthma that incorporates mental health professionals in the treatment of poorly controlled asthma and perhaps of asthma in general is recommended.
 

Background: Pain following brain surgery is a significant problem. Infiltration of the scalp with local intradermal anesthetics was suggested for postoperative pain control but was assessed only in the first hour postoperatively.

Objectives: To evaluate wound infiltration with a single dose of metamizol (dipyrone) for postoperative pain control in patients undergoing awake craniotomy.

Methods: This open, prospective, non-randomized observational study, conducted in anesthesiology and neurosurgical departments of a teaching hospital, included 40 patients undergoing awake craniotomy for the removal of brain tumor. Intraoperative anesthesia included wound infiltration with lidocaine and bupivacaine, conscious sedation using remifentanil and propofol, and a single dose of metamizol (dipyrone) for postoperative pain control. Outcome was assessed by the Numerical Pain Scale on arrival at the postoperative care unit, and 2, 4 and 12 hours after the end of surgery.

Results: On arrival at the postoperative care unit, patients reported NPS[1] scores of 1.2 ± 1.1 in a scale of 0–10 (mean ± SD) (median = 1, range 0–4). The scores were 0.8 ± 0.9, 0.9 ± 0.9, and 1 ± 0.9 at 2 hours, 4 hours, and 12 hours after the end of surgery, respectively. Based on patients' complaints and NPS lower then 3, 27 patients did not require any supplementary analgesia during the first 12 postoperative hours, 11 patients required a single dose of oral metamizol or intramuscular diclofenac, one patient was given 2 mg of intravenous morphine, and one patient required two separate doses of metamizol.

Conclusions: Although the clinical setup prevents the use of placebo local analgesia as a control group, the results suggest the possible role of local intradermal infiltration of the scalp combined with a single dose of metamizol to control postoperative pain in patients undergoing craniotomy.

Background: Spontaneous coronary reperfusion occurs in 7–27% of patients with ST elevation myocardial infarction, and is an independent predictor of myocardial salvage, percutaneous coronary intervention success, and improved outcome.

Objectives: To determine the optimal PCI[1] time for patients admitted to the hospital due to STEMI[2] with SCR[3].

Methods: We performed a retrospective analysis of all patients admitted to the coronary care unit between July 2002 and November 2004 with a diagnosis of STEMI with SCR.

Results: The study group comprised 86 patients. There was not a single reinfarction episode during an observation period of 6579 patient hours. Cardiac catheterization was executed early (< 24 hours from pain onset) in 26 patients and late (> 24 hours) in 55. Pre-PCI angiographic TIMI flow 2–3 was seen in > 95% in both groups. PCI was performed more frequently in the “early” group (P = 0.024), while multi-vessel coronary artery disease (P = 0.094) requiring coronary bypass surgery (P = 0.056) was observed more frequently in the “late catheterization” group. Myocardial infarction and angina pectoris at 30 days occurred more frequently in the early catheterization group (P = 0.039), however no difference in any major adverse cardiac events was detected during long-term follow-up (491 ± 245 days).

Conclusions: Reinfarction after STEMI with SCR is a rare event. Early PCI in patients with STEMI and SCR, even when executed with aggressive anti-platelet therapy, seems to result in an excess of early MACE, without any long-term advantage. Prospective randomized trials should determine the optimal PCI timing for these patients.

Background: Endothelial dysfunction is recognized as a major factor in the development of atherosclerosis and it has a prognostic value.

Objectives: To detect the long-term association of peripheral vascular endothelial function and clinical outcome in healthy subjects and patients with cardiovascular disease.

Methods: We prospectively assessed brachial artery flow-mediated dilation in 110 consecutive subjects (46 CVD[1] patients and 64 healthy controls), mean age 57 ± 11 years; 68 were men. After an overnight fast and discontinuation of all medications for ≥ 12 hours, percent improvement in FMD and nitroglycerin-mediated vasodilatation were assessed using high resolution ultrasound.

Results: %FMD[2] but not %NTG[3] was significantly lower in CVD patients (9.5 ± 8.0% vs. 13.5 ± 8.0%, P = 0.012) compared to healthy controls (13.4 ± 8.0% vs. 16.7 ± 11.0%, P = 0.084; respectively). In addition, an inverse correlation between %FMD and the number of traditional CVD risk factors was found among all study participants (r = -0.23, P = 0.015) and healthy controls (r = -0.23, P = 0.036). In a mean follow-up of 15 ± 2 months, the composite CVD endpoints (all-cause mortality, myocardial infarction, hospitalization for heart failure or angina pectoris, stroke, coronary artery bypass grafting and percutaneous coronary interventions) were significantly more common in subjects with FMD < 6% compared to subjects with FMD > 6% (33.3% vs. 12.1%, P < 0.03, respectively).
Conclusions: Thus, brachial artery %FMD provides important prognostic information in addition to that derived from traditional risk factor assessment

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

Background: During the last decade new surgical techniques for mitral valve repair were developed. We have been using those techniques in order to widen the spectrum of patients eligible for MV[1] repair.

Objectives: To assess the operative and mid-term results a wide variety of surgical techniques.

Methods: From January 2004 through December 2006, 213 patients underwent MV repair in our institution. Valve pathology was degenerative in 123 patients (58%), ischemic in 37 (17%), showed annular dilatation in 25 (12%), endocarditis in 16 (8%), was rheumatic in 13 (6%), and due to other causes in 14 (7%). Preoperative New York Heart Association score was 2.35 ± 0.85 and ejection fraction 53 ± 12%. Isolated MV repair was performed in 90 patients (42%) and 158 concomitant procedures were done in 123 patients (58%). A wide variety of surgical techniques was used in order to increase the number of repairs compared to valve replacement.

Results: There were 7 in-hospital deaths (3.3%). NYHA[2] class improved from 2.19 ± 0.85 to 1.4 ± 0.6, and freedom from reoperation was 100%. Echocardiography follow-up of patients with degenerative MV revealed that 93% of the patients (115/123) were free of mitral regurgitation greater than 2+ grade. In patients operated by a minimal invasive approach there were no conversions to sternotomy, no late deaths, none required reoperation, and 96% were free of MR[3] greater than 2+ grade. The use of multiple surgical techniques enabled the repair of more than 80% of pure MR cases.

Conclusions: MV repair provides good perioperative and mid-term results, and supports the preference for MV repair over replacement, when feasible. Multiple valve repair techniques tailored to different pathologies increases the feasibility of mitral repair.
