Abstract

Background: In the era of primary percutaneous coronary intervention (PPCI), information on the incidence and prognostic significance of high degree atrioventricular block (AVB) in ST elevation myocardial infarction (STEMI) patients is limited.

Objectives: To assess the incidence, time of onset, predictors and prognostic significance of high degree AVB in a large cohort of consecutive STEMI patients undergoing PPCI.

Methods: We retrospectively studied 1244 consecutive STEMI patients undergoing PPCI. Patient records were reviewed for the presence of high degree AVB, its time of occurrence and relation to in-hospital complications, as well as long-term mortality over a 5 year period.

Results: High degree AVB was present in 33 patients (3.0%), in 25 (76%) of whom the conduction disorder occurred prior to PPCI. Twelve patients (36%) required temporary pacing, all prior to or during coronary intervention, and all AVB resolved spontaneously before hospital discharge. AVB was associated with a significantly higher 30 day (15 % vs. 2.0%, P = 0.001) and long-term mortality rate (30% vs. 6.0%, P < 0.001). Time of AVB had no effect on mortality. In a multivariate regression model, AVB emerged as an independent predictor for long-term mortality (hazard ratio 2.8, 95% confidence interval 1.20–6.44, P = 0.001).

Conclusions: High degree AVB remains a significant prognostic marker in STEMI patients in the PPCI era, albeit transient.

Background: A clavicular fracture accounts for 2.6%–5% of adult fractures. Fractures in the middle-third (OTA 15-B) represent 69%–82% of all clavicular fractures. There is no consensus among orthopedic surgeons regarding treatment for these fractures; many support conservative treatment even for displaced middle-third clavicular fractures, while others choose operative treatment.

Objectives: To assess the attitudes of orthopedic surgeons regarding treatment of displaced mid-shaft clavicular fractures.

Methods: We conducted a survey in which we interviewed orthopedic surgeons from various countries during the 2012 EFORT meeting in Berlin. The questionnaire included an X-ray of a displaced middle-third clavicular fracture, as well as questions regarding the surgeon’s proposed treatment plan.

Results: A total of 177 orthopedic surgeons completed the questionnaire; 49% preferred operative treatment for a displaced middle-third clavicular fracture. Among the orthopedic trauma specialists, 58% suggested operative treatment, as did 82% of shoulder specialists. Most surgeons preferred a locking plate for fixation.

Conclusions: The treatment approach for a displaced middle-third clavicular fracture seems to be evenly split between conservative and operative approaches. The tendency toward operative treatment was even more remarkable among orthopedic trauma specialists and shoulder specialists who completed the questionnaire. Most surgeons prefer a locking plate as a fixation system for this type of fracture. 

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.

Objectives: To investigate whether the change in protocols over the years resulted in an outcome difference at two hospitals in Israel.

Methods: We thoroughly reviewed the records of 153 patients from Sheba Medical Center and Soroka Medical Center, of whom 106 comprised the study group. The patients were divided into two groups according to the treatment protocol used: 40 patients with the 1989/93 protocol and 66 with the 1999/2003 protocol. Outcome was analyzed for the two groups.

Results: We found a significant difference in disease-free survival (DFS) between the two groups for B cell-ALL (B-ALL) patients who achieved complete remission after induction. There was no difference in overall survival. We did not find any difference in outcome for T cell-ALL patients or for CD20-positive patients.

Conclusions: In our retrospective analysis, GMALL 99/2003 led to a better DFS for B-ALL patients who were in complete remission after induction. This is possibly related to the differences in medications between the protocols, but may also be due to better supportive care. Despite the proven advantage of the newer protocols regarding overall survival, in our experience there was no other significant difference between the two regimens. 

Objectives: To assess the preliminary results of transcatheter mitral valve leaflet repair (TMLR) in a single academic center.

Methods: Data were collected prospectively in the cardiology department of Rabin Medical Center in 2012. Ten consecutive patients (age 69.3 ± 15.9 years, ejection fraction 36.5 ± 9.4) who were poor surgical candidates with severe functional MR underwent general anesthesia, followed by trans-septal puncture and a TMLR procedure using the MitraClip device.

Results: All 10 patients were considered to have severe functional MR prior to TMLR treatment and were all symptomatic; the mean New York Heart Association (NYHA) class was 3.4 ± 0.5. The MR severity was 4 ± 0. There were no immediate complications or failures of the procedure. One patient died on day 5 due to massive gastrointestinal bleeding. Immediately following TMLR all 10 patients showed a profound MR reduction to a mean severity grade of 1.6 ± 0.6. At one month after the procedure, NYHA had decreased to an average of 1.7 ± 1.0 and was at least grade 2 in all but one patient. After 6 months the MR remained ≤ 2 in six of eight patients, with a NYHA average of 1.4 ± 0.5.

Conclusions: The MitraClip procedure was shown to be relatively safe, providing significant clinical benefits to a relatively sick population with severe MR. It is therefore an important alternative to surgery in these high risk patients.

Objectives: To investigate the 30 day clinical outcome of the first 300 consecutive patients treated with transfemoral TAVI at the Tel Aviv Medical Center.

Methods: The CoreValve was used in 250 patients and the Edwards-Sapien valve in 50 patients. The mean age of the patients was 83 ± 5.3 years (range 63–98 years) and the mean valve area 0.69 ± 0.18 cm² (range 0.3–0.9 cm²); 62% were women.

Results: The procedural success rate was 100%, and 30 day follow-up was done in all the patients. The average Euro-score for the cohort was 26 ± 13 (range 1.5–67). Total in-hospital mortality and 30 day mortality were both 2.3% (7 patients). Sixty-seven patients (22%) underwent permanent pacemaker implantation after the TAVI procedure, mostly due to new onset of left bundle brunch block and prolonged PR interval or to high degree atrioventricular block. The rate of stroke was 1.7% (5 patients). Forty-one patients (13.7%) had vascular complications, of whom 9 (3%) were defined as major vascular complications (according to the VARC definition).

Conclusions: The 30 day clinical outcome in the first 300 consecutive TAVI patients in our center was favorable, with a mortality rate of 2.3% and low rates of stroke (1.7%) and major vascular complications (3%).

Background: On 4 February 2008, two terrorists armed with suicide bombs arrived at the open market in the southern Israeli city of Dimona. One detonated his bomb at approximately 10:30 a.m. causing multiple casualties. Short-term emotional effects and acute stress reactions usually appear among survivors after such incidents.

Objectives: To compare the differences in emotions and in disturbances of daily life activities that emerge a couple of days following such an event and to identify patterns of stress development among resilient and low-resilient members of the population in Dimona and in the general population of Israel.

Methods: A telephone survey of two randomly selected representative samples of adults (428 Israeli residents and 250 Dimona residents) was conducted 2 days after the event.

Results: A higher prevalence of stress and fear and a lower prevalence of joy were reported among the population of Dimona compared to the general population in Israel (P < 0.05). Differences were also recorded when the population of Dimona was categorized by their personal degree of resilience (P < 0.05). A higher prevalence of disturbances in daily life activities and changes in leisure activity was found in the low-resilient population in Dimona (P < 0.01).

Conclusions: This study demonstrates that following a public terror event, self-reported low-resilient subjects have a higher prevalence of disturbances in daily life activities, as well as adverse emotional responses. These differences must be addressed by the relevant social service agencies for immediate public intervention
