Objectives: To assess the prevalence of reversible and treatable cardiovascular risk factors among 26’477 healthy Israeli adults: 23’339 men and 3138 women aged 25-55 years.

Methods: We collected data during routine examinations performed as part of a screening program for Israel Defense Force personnel.

Objectives: To review our experience with cricotracheal resection and to assess related pitfalls and complications.

Methods: We examined the records of all patients who underwent CTR[1] in a tertiary referral medical center during the period January 1995 to April 2005.

Results: The study included 61 patients (16 women and 45 men) aged 15–81 years. In 17 patients previous interventions had failed, mostly dilatation and T-tube insertion. Complete obstruction was noted in 19 patients and stenosis > 70% in 26. Concomitant lesions included impaired vocal cord mobility (n=8) and tracheo-esophageal fistula (n=5). Cricotracheal anastomosis was performed in 42 patients, thyrotracheal in 12 and tracheotracheal in 7. A staged procedure was planned for quadriplegic patients and for three others with bilateral impaired vocal cord mobility. Restenosis occurred in six patients who were immediately revised with T-tube stenting. Decanulation was eventually achieved in 57 patients (93.4%). Complications occurred in 25 patients, the most common being subcutaneous emphysema (n=5). One patient died of acute myocardial infarction on the 14th postoperative day.

Conclusions: CTR is a relatively safe procedure with a high success rate in primary and revised procedures. A staged procedure should be planned in specific situations, namely, quadriplegics and patients with bilateral impaired vocal cord mobility. 

Objectives: To assess the effects of the recently introduced co-payment for consultant specialist services on patients' utilization of these services in southern Israel.

Methods: Computerized utilization data on specialists' services for 6 months before and 6 months after initiation of co-payment were retrieved from the database of Israel's largest health management organization.

Results: A decrease of 4.5% was found in the total number of visits to Soroka Medical Center outpatient clinics and of 6.8% to community-based consultants. An increase of 20.1% was noted in the number of non-actualized visits at the outpatient clinics. A decrease of 6.2% in new visits was found in the hospital outpatient clinics and of 6.5% in community clinics. A logistic regression model showed that the residents of development towns and people aged 75+ and 12–34 were more likely not to keep a prescheduled appointment.

Conclusion: After introduction of a modest co-payment, a decrease in the total number of visits to specialists with an increase in "no-shows" was observed. The logistic regression model suggests that people of lower socioeconomic status are more likely not to keep a prescheduled appointment.

Objectives: To report a 14 year experience of RFA[2] of the slow pathway in patients with AVNRT treated in our laboratory.

Methods: A total of 901 consecutive patients (aged 9–92, mean 50.8 ± 18.2 years) underwent RFA of the slow pathway. All patients had sustained AVNRT induced with or without intravenous administration of isoproterenol. A standard electrophysiologic method with three diagnostic and one ablation catheter was used in 317 patients (35.2%); in the remaining 584 patients (64.8%), only two electrode catheters (one diagnostic, one ablation) were used ("two-catheter approach").

Results: Catheter ablation of the slow pathway abolished AVNRT induction in 877 patients (97.3%). In 14 patients (1.6%) the procedure was discontinued while in 10 (1.1%) the procedure failed. In 864 patients (95.9%) there were no complications. Transient or permanent AV block occurred during the procedure in 31 patients (3.4%), of whom 8 (0.9%) eventually required pacemaker insertion (n=7) or upgrade of a previously implanted VVI pacemaker (n=1) during the month following the procedure. The number of catheters used did not significantly affect the rate of results or complications of the ablation procedure. The success and complication rates remained stable over the years, although a significant trend for increased age and associated heart disease was observed during the study period.

Conclusions: The results of this single-center large study, which included patients with a wide age range, showed results similar to those of previous studies. The use of a "two-catheter approach" (one diagnostic and one ablation) was as effective and safe as a multi-catheter approach.

Objectives: To compare leukocyte counts and blood levels of various inflammatory cytokines in children and adults diagnosed with community-acquired bronchopneumonia.

Methods: We prospectively evaluated all pediatric and adult patients admitted for bronchopneumonia based on clinical and chest X-ray findings.. Blood was drawn for complete blood count and serum concentration of the following cytokines: granulocyte colony-stimulating factor, interleukins-6, 8 and 10, interferon-gamma, tumor necrosis factor, as well as matrix metalloproteinase-9 and intercellular adhesion molecule-1.

Results: There were 31 children and 32 adults. The patients in both groups had similar parameters of infection severity. None of them required admission to the Intensive Care Unit. Mean (± SD) leukocyte counts in the pediatric and adult groups were 21,018/mm (± 10,420) and 12,628/mm (± 6735) respectively (P = 0.02). Age was inversely correlated with leukocytes in the pediatric group (P = 0.0001). A significant inverse correslation was also found between age and platelet counts. Although cuytokine levels in both groups were not significantly different, age was

Conclusions: The immune response in community-aquired bronchopneumonia is, at least partly, age-dependent.

Background: Diabetic macular edema causes visual loss in almost one-third of diabetic patients. There is currently no treatment for the accompanying cystoid foveal changes.

Objectives: To assess the clinical outcome, i.e., change in visual acuity, in patients treated with steroids for long-standing diabetic macular edema with foveal cystoid changes.

Methods: In the ophthalmology department of a tertiary care university‑affiliated medical center and the ophthalmology service of a health management organization, 46 diabetic subjects (56 eyes) who had diabetic macular edema with cystoid foveal changes received one intravitreal injection of 4 mg triamcinolone acetonide.

Results: The mean baseline (pre‑injection) visual acuity of 0.21 increased to 0.31 and 0.48 at 1 and 3 months, respectively, after which it decreased to 0.33 at 6 months. The mean intraocular pressure was 15.07 mmHg at baseline, 15.83 at day 1, gradually rising to 17.16, 18.38 and 18.57 mmHg at 1, 3 and 6 months respectively. Three patients suffered immediate visual decline after the injection.

Conclusions: Intravitreal triamcinolone acetonide may be a therapeutic option for long‑standing diabetic macular edema with foveal cystoid changes.
 

Background: Cardiovascular disease is now well established as a multifactorial disease. In a given individual, the level of cardiovascular risk is due to the interaction between genetic and environmental components. The BIP cohort comprised 3000 patients with cardiovascular disease who were tested for the benefits of bezafibrate treatment. This cohort has the data for the lipid profile of each individual, fibrinogen, Insulin, as well as clinical, demographic and lifestyle parameters

Objectives: To genotype up to 64 variable sites in 36 genes in the BIP cohort. The genes tested in this assay are involved in pathways implicated in the development and progression of atherosclerotic plaques, lipid and homocystein metabolism, blood pressure regulation, thrombosis, rennin-angiotensin system, platelet aggregation, and leukocyte adhesion.

Methods:  DNA was extracted from 1000 Israeli patients from the BIP cohort. A multilocus assay, developed by the Roche Molecular System, was used for genotyping. Allele frequencies for some of the markers were compared to the published frequencies in a healthy population (the French Stanislas cohort, n=1480).

Results: Among the 26 comparable alleles checked in the two cohorts, 16 allele frequencies were significantly different from the healthy French population: ApoE (E3, E2, E4), ApoB (71ile), ApoC (3482T, 455C, 1100T, 3175G, 3206G), CETP (405val), ACE (Del), AGT (235thr), ELAM (128arg); p<0001 and LPL (93G, 291Ser, 447ter); p < 005.

Conclusions: Although a comparable healthy Israeli population study is needed for more precise interpretation of these results, frequency differences in these polymorphic alleles, associated with lipid metabolism, renin-angiotensin system and leukocyte adhesion mechanism, between CVD patients and healthy individuals nevertheless implicate these candidate genes as predisposing for CVD.lic safety.
