Background: A major psychological sequel of terrorist attacks is post-traumatic stress disorder. The relation between certain psychological factors specific to terrorist attacks (e.g., perceived control attributed to oneself/to the military, anticipated duration of terrorism) and PTSD[1] symptoms have not been examined.

Objective: To examine the prevalence, correlates and moderators of PTSD-like symptoms following terrorist attacks in Israel.

Methods: Soon after a long wave of terrorist attacks in Israel in 2002, a convenience sample of 149 Israelis from five cities was assessed for terrorist attack exposure, perceived control, control attributed to the government/military, anticipated duration of the terrorism wave (predictability), and frequency of listening to the news. PTSD-like symptoms were assessed with a brief self-report scale.

Results: We found that 15.4% of the sample was directly exposed to a terrorist attack and 36.5% knew someone close who had been exposed to an attack. “Clinically significant” PTSD-like symptoms were reported by 10.1% of the sample. Correlates of PTSD-like symptoms were: perceived control in men, government control, and education in women (all inversely correlated to PTSD symptoms), and news-listening frequency in women (positively correlated to PTSD symptoms). PTSD-like symptoms were attenuated by the ability to predict the duration of the terrorism wave only in citizens exposed to an attack, and by perceived government control only among citizens listening infrequently to the news.

Conclusions: This study revealed that approximately 10% of Israelis in our sample had relatively frequent PTSD-like symptoms. Correlates of PTSD-like symptoms differed between men and women, and moderator effects were found. These findings reveal additional moderators that may have implications for treating PTSD following terrorist attacks.

Background: The infant mortality rate is a health status indicator.

Objectives: To analyze the differences in infant mortality rates between Jews and Arabs in Israel between 1975 and 2000.

Methods: Data were used from the Central Bureau of Statistics and the Department of Mother, Child and Adolescent Health in the Ministry of Health.

Results: The IMR[1] in 2000 was 8.6 per 1,000 live births in the Israeli Arab population as compared to 4.0 in the Jewish population. Between 1970 and 2000 the IMR decreased by 78% among Moslems, 82% among Druze, and 88% among Christians, as compared to 79% in the Jewish population. In 2000, in the Arab population, 40% of all infant deaths were caused by congenital malformations and 29% by prematurity, compared to 23% and 53%, respectively, in the Jewish population. Between 1970 and 2000 the rate of congenital malformations declined in both the Arab and Jewish populations. In the 1970s the rate was 1.4 times higher in the Arab community than in the Jewish community, and in 2000 it was 3.7 times higher.

Conclusion: As in the Jewish population, the IMR in the Arab community has decreased over the years, although it is still much higher than that in the Jewish community. Much remains to be done to reduce the incidence of congenital malformations among Arabs, since this is the main cause of the high IMR in this population.

Background: Although the home is perceived to be a safe haven, it is a scene of numerous injuries.

Objectives: To characterize home injury in Israel, the victims, injury circumstances and outcomes, and to identify groups at high risk for injury in order to focus future interventions and thus effectively prevent these injuries and their associated hospitalizations.

Methods: We analyzed 5 year records (1997–2001) from the National Trauma Registry of all patients arriving at eight trauma centers following home injury and admitted to hospital, transferred to another medical center or died in the emergency department.

Results: The study group included 26,921 patients, constituting 34% of all unintentional hospitalized trauma patients. Twenty-seven percent were children (0–4 years) and 37% were elderly (≥ 65 years) – the two age groups whose home injury accounted for most of the trauma injuries. Among children more boys (59%) than girls (41%) were injured, but the opposite was true for the elderly (30% males and 70% females). The share of females among the home-injured increased with age. Falls caused 79% of all home injuries (97% among the elderly) and burns 9%, increasing to 18% among children (0–4 years). Among non-Jewish home-injured patients, infants predominated (50% compared to 20% among Jews). Moderate to critical injuries amounted for 42%, with 38% of the home injured and 60% of the elderly requiring surgery. The clinical and economic consequences of home injuries differed according to the type of injury, with burns carrying the heaviest toll of prolonged intensive care and hospital stay. Overall, hospital stay averaged 6.2 days per patient (median 3 days).

Conclusions: Falls among the elderly, burns among children, and a high prevalence of hospitalization among non-Jewish children define groups at high risk for home injuries. Prevention programs should be based on these findings and should focus on the more vulnerable groups.

Background: Idiopathic left ventricular tachycardia with a right bundle branch block configuration and left axis deviation, first described by Belhassen et al., is a rare electrocardiographic-electrophysiologic entity. Radiofrequency catheter ablation has been proposed as a good therapeutic option, but the best criteria for determining the optimal site of ablation are still under debate.

Objectives: To report the clinical features, electrophysiologic characteristics, results of RFA[1], and long-term outcome in 18 patients with "Belhassen's VT” treated in our laboratory during the last 10 years, stressing the best electrophysiologic criteria for determining the optimal site of ablation.

Methods: Eighteen consecutive patients with this specific VT[2] underwent RFA in our laboratory during the last 10 years. RFA was acutely successful in 17 patients after one or two procedures (15 and 2 patients, respectively) using 4.1 ± 2.2 RF pulses. The putative ablation sites were defined by good pace-mapping (3 patients), earliest recorded Purkinje spike prior to the QRS onset during VT or sinus rhythm (6 patients), earliest endocardial activation during VT (1 patient), and diastolic potential preceding the Purkinje spike during VT and/or late diastolic potential in sinus rhythm (7 patients). In the patients with a definite successful ablation, the ratio of successful to unsuccessful radiofrequency pulse delivery to the diastolic potential site was compared to that of other methods. The ratio of successful RFA at the diastolic potential site (5:8) was higher than in the other methods (8:31), and the difference was statistically significant (P = 0.05). Successful ablation sites were more basal when the diastolic potential site was chosen.

Conclusion: The results of the present study confirm the high success rate and safety of RFA using conventional techniques in the management of “Belhassen VT,” suggesting that this procedure can be proposed as a first-line therapy. Ablating at a site demonstrating a late diastolic potential is at least as effective as ablating at a ventricular exit site, although the use of combined electrophysiologic criteria may be the optimal approach.
