Aging has been associated with perceived lowering of health, especially in post-traumatic individuals. The effects may be more complex or even different for Holocaust survivors as they age due to their inherited resilience and life perspective. A cross-sectional study was conducted of Holocaust survivors and a matched comparison group recruited from the general Israeli population. All participants underwent a personal interview and completed the Cumulative Illness Rating Scale and a survey of subjective Likert-scale questions about perceived health. The study comprised 214 older adults: 107 Holocaust survivors and 107 comparison participants; 101 women and 113 men. The mean age for the participants was 80.7 ± 4.7 years (range 68–93). Holocaust survivors did not differ from comparison subjects in general health measures (mean 51.50 ± 3.06 vs. 52.27 ± 3.24, respectively). However, the Holocaust survivors' subjective health was significantly lower, F (2,211) = 4.18, P < 0.05, and associated with decreased quality of life. The present study demonstrates the complex interplay between general and subjective health and suggests that future interventions need to focus on improving the psychological and social well-being of Holocaust survivors to achieve successful aging.

Background: Pre-exposure prophylaxis (PrEP) for populations at high risk for human immunodeficiency virus (HIV) is still not available in Israel.

Objectives: To analyze post-exposure prophylaxis (PEP) treatment adherence rates among adult men in Tel Aviv, Israel, who have sex with men (MSM), and to obtain data on the demographics of PEP users, exposure types, timeline of exposure and PEP administration, incidence of side effects, number of treatments per individual, and satisfaction with selected elements of treatment provision.

Methods: The authors conducted an observational cohort study of adult MSM who requested PEP treatment in the Tel Aviv Sourasky Medical Center. Information from patients receiving treatment between January 2013 and June 2014 was obtained through telephone interviews by means of a 30-item questionnaire.

Results: Of 336 individuals requesting PEP treatment, 255 (75.9%) were adult MSM, and 100 (39.2%) satisfactorily completed the interview. The average age of the study cohort was 32.4 years (standard deviation of 7.5). Ninety-one (91%) reported completing a full 28-day course of treatment, 84% reported side effects, and 20% underwent multiple courses. Satisfaction was high for interactions with the HIV specialists. Patient experience with PEP treatment in the emergency room setting, and follow-up were inadequate deficient.

Conclusions: PEP adherence rates in Tel Aviv were significantly higher than previously reported. PEP should be administered in designated community settings. PrEP as a general treatment policy might suit the MSM population in Tel Aviv.

Background: A growing number of Eritrean and Sudanese refugees seek medical assistance in the labor and delivery ward of our facility. Providing treatment to this unique population is challenging since communication is limited and pregnancy follow-up is usually absent.

Objectives: To compare the perinatal outcome of refugees and Israeli parturients.

Methods: The medical and financial records of all refugees delivered between May 2010 and April 2011 were reviewed. Perinatal outcome was compared to that of native Israeli controls.

Results: During this period 254 refugees were delivered (2.3% of deliveries). Refugees were significantly younger and leaner. They had significantly more premature deliveries under 37 weeks (23 vs. 10, P = 0.029) and under 34 weeks gestation (9 vs. 2, P = 0.036) with more admissions to the neonatal intensive care unit (15 vs. 5, P = 0.038). Overall cesarean section rate was similar but refugees required significantly more urgent surgeries (97% vs. 53%, P = 0.0001). Refugees had significantly more cases of meconium and episiotomies but fewer cases of epidural analgesia. There were 2 intrauterine fetal deaths among refugees, compared to 13 of 11,239 deliveries during this time period (P = 0.036), as well as 7 pregnancy terminations following sexual assault during their escape. Sixty-eight percent of refugees had medical fees outstanding with a total debt of 2,656,000 shekels (US$ 767,250).

Conclusions: The phenomenon of African refugees giving birth in our center is of unprecedented magnitude and bears significant medical and ethical implications. Refugees proved susceptible to adverse perinatal outcomes compared to their Israeli counterparts. Setting a pregnancy follow-up plan could, in the long run, prevent adverse outcomes and reduce costs involved in treating this population.

Background: Stentless aortic bioprostheses were designed to provide improved hemodynamic performance and potentially better survival.

Objectives: To report the outcomes of patients after aortic valve replacement with the Freestyle® stentless bioprosthesis in the Tel Aviv Medical Center followed for ≤ 15 years.

Methods and Results: Between 1997 and 2011, 268 patients underwent primary aortic valve replacement with a Freestyle bioprosthesis, 211 (79%) of them in the sub-coronary position. Mean age, Charlson comorbidity index and Euro-score were 71.0 ± 9.2 years, 4.2 ± 1.5 and 10.2 ± 11 respectively, and 156 (58%) were male. Peak and mean trans-aortic gradient decreased significantly (75.0 ± 29.1 vs. 22.8 ± 9.6 mmHg, P < 0.0001; and 43.4 ± 17.2 vs. 12.1 ± 5.4 mmHg, P < 0.0001 respectively) in 3 months of follow-up. Mean overall follow-up was 4.9 ± 3.1 years and was complete in all patients. In-hospital mortality was 4.1% (n=11) but differed significantly between the first 100 patients operated before 2006 and the last 168 patients operated after January 2006 (8 vs. 3 patients, 8.0% vs. 1.8%, P = 0.01). Overall, 5 and 10 year survival rates were 85 ± 2.5% and 57.2 ± 5.7%, respectively. Five year survival was markedly improved in patients operated after January 2006 compared to those operated in the early years of the experience (92.3 ± 2.3% vs. 76.0 ± 4.4%, P = 0.0009). All the 21 octogenarians operated after January 2006 survived surgery, with excellent 5 year survival (85.1 ± 7.9%). Six patients required reoperation during follow-up: structural valve deterioration in five and endocarditis in one.

Conclusions: Aortic valve replacement with the Freestyle bioprosthesis provides good long-term hemodynamic and clinical outcomes, even in octogenarians. Valve calcification is the major (and rare) mode of valve deterioration leading to reoperation in these patients. 

Background: There is a growing shortage of anesthesiologists practicing in Israel. This shortage is in contrast with the United States where anesthesiology has become a very desired specialty.

Objectives: To discover what factors attract Israeli students to choose a residency and how students view the option of choosing anesthesiology.

Methods: We sent questionnaires to students in the Israeli and American programs at Tel Aviv University’s Sackler Faculty of Medicine asking about factors that influenced their choice of residency and the advantages and disadvantages of a residency in anesthesiology. Although the students were studying at the same medical school and hospitals, students in the Israeli program were planning to enroll in Israeli residency programs while students in the American program planned to apply for residency in the United States.

Results: A significantly larger proportion of American students (12.9%) were interested in an anesthesiology residency when compared with the Israeli students (0%) (P = 0.034). American students considered salary and working conditions to be advantages of the anesthesiology residency while Israeli students considered Israeli working conditions and salaries to be a disadvantage.

Conclusions: Whereas there is considerable interest among American students at Sackler Medical School in an anesthesia residency, there is little interest among Israeli students.
 

Background: Radiofrequency ablation has been suggested as first-line therapy in the management of accessory pathways. There are limited data on the results of ablation over years of experience.

Objectives: To assess the results and complications following RFA[1] of APs[2] performed in our institution over a 14 year period.

Methods: RFA was performed using deflectable electrode catheters positioned at the mitral or tricuspid annulus. The site of the AP was localized by electrophysiological study and radiofrequency energy was applied via the tip of the catheter

Results: The study cohort comprised 508 consecutive patients (64.2% males, mean age 33.6 ± 15.1 years) who underwent 572 RFA procedures for ablating 534 APs. A single AP was found in 485 (95.5%) patients while multiple APs were noted in 23 patients (4.5%). The APs were manifest, concealed or intermittent in 46.8%, 44.4% and 8.8% of cases, respectively. AP distribution was as follows: left free wall (56.6%), posteroseptal (23%), right anteroseptal (7.9%), right free wall (6.2%), midseptal (3.4%) and right atriofascicular (3.0%). Acute successful rates for a first or multiple ablation attempts were 93.1% and 95.3%, respectively. At a first ablation attempt, acute success and failure rates were the highest for midseptal (100%) and right atriofascicular (12.5%) APs respectively. Right anteroseptal APs were associated with the highest rate (23.9%) of discontinued or non-attempted procedures. Recurrent conduction in an AP after an initial successful ablation was observed in 9.9% of cases; it was the highest (24.2%) for right free wall APs and the lowest (5.0%) for left free wall APs. During follow-up (85 ± 43 months), definite cure of the AP was achieved in 94.9% of cases following a single or multiple procedures: midseptal (100%), left free wall (98%), right free wall (97%), posteroseptal (92.7%), right atriofascicular (87.5%) and right anteroseptal (78.5%). A non-fatal complication occurred in 18 patients (3.5%), more frequently in females (6.6%) than in males (1.8%) (P < 0.01). The two major complications (pericardial effusion and myocardial ischemic events) mainly occurred during RFA of a left free wall AP using a retrograde aortic approach. Catheter-induced mechanical trauma to APs was observed in 56 cases (10.5%). Mechanical trauma mainly involved right atriofascicular (43.8%) and right anteroseptal (38.1%) APs and contributed to the low success rate of RFA at these AP locations. During the 14 year period, our learning curve was achieved quickly in terms of success rate, although the most significant complications were observed at the beginning of our experience.

Conclusions: The results of this study confirm the efficacy and safety of RFA and suggest that it is a reasonable first-line therapy for the management of APs at any location.

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.

Background: The proportion of motorcyclists injured in road accidents in Israel is larger than their proportion among road users.

Objectives: To identify factors contributing to the risk of injury for motorcyclists as compared to drivers of other motor vehicles.

Methods: We retrieved and analyzed National Trauma Registry data on drivers, aged 16 and above, who were involved in traffic accidents and hospitalized between 1 January 1997 and 30 June 2003.

Results: The study group comprised 10,967 patients: 3,055 (28%) were motorcyclists and 7,912 (72%) were drivers of other motor vehicles. A multiple logistic regression revealed that Tel Aviv, the busiest metropolitan city in Israel, is a risk for motorcycle injury as compared to other regions; males have an increased risk compared to females; and age is a protecting factor since the risk of injury as a motorcyclist decreases as age increases. Nevertheless, the population of injured motorcyclists in Tel Aviv was significantly older (mean age 32.5 years vs. 28.6 elsewhere; t-test P < 0.0001). Twenty percent (n=156) of the injured motorcyclists in Tel Aviv were injured while working, compared to 9.5% (n=217) in other regions (chi-square P < 0.0001). Motorcycle injuries in Tel Aviv were of lower severity (7.7% vs. 16.4% according to the Injury Severity Scale 16+, c2 P < 0.0001), and had lower inpatient death rates (1.2% vs. 2.5%, c2 P = 0.001).

Conclusions: Tel Aviv is a risk for motorcycle injury compared to other regions, males have an increased risk compared to females, and age is a protecting factor. The proportion of motorcyclists in Tel Aviv injured while working is double that in other regions
