 In acute myocardial ischemic syndrome the electrocardiogram is capable of providing sophisticated information on coronary artery anatomy (the culprit artery, the level of obstruction, the arterial dimension), along with the hemodynamics, molecular biological characteristics and ionic changes that occur in the involved and uninvolved ischemic musculature. In acute myocardial ischemia, during a sudden obstruction of a distal co-dominant right coronary artery the ECG may be able to discriminate between physiological and pathological remodeling, providing predictive information to differentiate low from high risk cases during acute inferior wall infarction.

 Background: Burn injuries are extremely common and may impose a serious load on public health around the world.

 Objectives: To compare mortality rates and length of hospitalization according to the identified risk factors, extent of burn, gender and age.

Methods: In this retrospective study, data from 558 archive files of hospitalization due to burns as the diagnosis in patients of all ages, between the years 2001 and 2002, were analyzed to identify the risk factors for mortality and length of hospitalization.

Results: Males comprised 62.4% of the hospitalized burn patients. The mortality rate was 3.2% (n=18) and among them 55.6% were women. Fifty percent of the fatality cases were over 48 years old, with statistically significant correlation of mortality rate and age. Most of the fatality cases (66.7%) had burns with total burn surface area (TBSA) larger than 40%. The multiple logistic regression model showed that leukocyte count on admission, TBSA, and age are the most important predictors of mortality. Smoke inhalation was not found to be an independent risk factor.

Conclusions: Using a statistical model for estimating the mortality rate, this study found that white blood cell count at admission, TBSA, and age were the most significant predictors of mortality.

 Background: Horse riding and horse handling are dangerous. There is a lack of knowledge concerning the incidence of hospitalization due to horse-related injuries and types of injuries in Israel. During the last two decades we have observed an increasing incidence of hospitalizations due to horse-related injuries at our medical center and noticed the frequent involvement of pediatric patients.

Objectives: To investigate these injuries with respect to type, incidence and modes of prevention.

Methods: A retrospective study of medical records was performed for all patients admitted to Assaf Harofeh Medical Center due to horse-related injury between January 1984 and December 2008. A telephone questionnaire was used to complete the data.

Results: Eighty-nine subjects (267 injuries) were included in the study. Most of them were not professional horse riders or horse handlers. Helmet use was reported in only 28% of the participants. The number of subjects with horse-related injuries and the percentage of pediatric involvement increased during the study period. Falling from a horse was the most frequent cause of injury (60.67%), followed by being kicked (13.4%). Head and extremities were the most affected areas. On admission, 33.7% had a potential severe injury score. Forty-two participants (47%) had underlying fractures, mostly in the upper extremities. In the pediatric population, 16.2% (vs. 0% adults) rode horses for therapeutic reasons. Seventeen subjects reported having long-term consequences.

Conclusions: The findings are similar to those described in other parts of the world. Horseback riding-related injuries are increasing, which emphasizes the need for safety education programs in Israel.

 Background: Few studies have addressed the ultrastructure of vascular permeability in urticaria.

Objectives: To describe the types of endothelial cell organelles involved in vascular permeability in drug-induced acute urticaria (DIAU).

Methods: Seven patients with DIAU were enrolled in the study. Biopsies of urticarial lesions and apparently normal skin were performed. The 14 collected fragments were processed with immunogold electron microscopy using single stains for tryptase and factor XIIIa (FXIIIa) and double immunogold labeling for both tryptase and FXIIIa.

Results: Some sections demonstrated mast cells in the degranulation process, in both anaphylactic and piecemeal degranulation. After double immunogold staining, 10 nm (FXIIIa) and 15 nm (tryptase) gold particles were both present, covering the granules in the mast cells, indicating that both tryptase and FXIIIa were localized within the granules of these cells. Interestingly, we found strong evidence of the presence of caveolae and vesico-vacuolar organelles (VVOs) in the endothelial cells of the biopsies. In addition to these findings, we were able to demonstrate the presence of tryptase and FXIIIa in the endothelial cells, in urticarial lesions and in apparently normal skin.

Conclusions: VVOs are present in the endothelial cells of post-capillary venules in DIAU. This is the first report on the expression of FXIIIa and tryptase in the cytoplasm of endothelial cells in urticaria.

 Background: Due to the war in Gaza in 2009, Ben-Gurion University’s Medical School for International Health with a student body of 165 international multicultural students canceled a week of classes. Third-year students continued clerkships voluntarily and fourth-year students returned to Israel before departing for clerkship in a developing country. A debriefing session was held for the entire school.

Objectives: To assess the academic and psychological effects of political conflict on students.

Methods: We asked all students to fill out an anonymous Google electronic survey describing their experience during the war and evaluating the debriefing. A team of students and administrators reviewed the responses.

Results: Sixty-six students (40% of the school) responded (first year 26%, second year 39%, third year 24%, fourth year 8%, taking time off 3%, age 23–40 years old). Eighty-three percent were in Israel for some portion of the war and 34% attended the debriefing. Factors that influenced individuals’ decision to return/stay in the war zone were primarily of an academic and financial nature. Other factors included family pressure, information from peers and information from the administration. Many reported psychological difficulties during the war rather than physical danger, describing it as “draining” and that it was difficult to concentrate while studying. As foreigners, many felt their role was undefined. Although there is wide variation in the war’s effect on daily activities and emotional well-being during that time, the majority (73%) reported minimal residual effects.

Conclusions: This study lends insight to the way students cope during conflict and highlights academic issues during a war. Open and frequent communication and emphasis on the school as a community were most important to students.

 Background: Radical prostatectomy is one option for treating localized prostate cancer, but it can cause functional impairment of the urogenital system.

Objectives: To describe the outcomes of radical prostatectomy as perceived by the patients, and their ways of coping with them.

Methods: We conducted a qualitative study of 22 men with localized prostatic cancer 1 year after surgery. The key questions related to the effect of the disease and the surgery on their lives and their view on the value of the surgery.

Results: The surgery was perceived as a necessary solution for the diagnosed cancer. All the participants suffered from varying degrees of urinary incontinence and erectile dysfunction. Urinary incontinence caused severe suffering. The impaired sexual ability affected relations with partners and led to feelings of shame and guilt and a decreased sense of self-esteem. In retrospect, the participants still viewed the surgery as a life-saving procedure. Faith in the surgeon contributed to their affirmation of the decision to undergo surgery despite the difficulties.

Conclusions: Patients were prepared to suffer the inevitable physical and psychological sequelae of radical prostatectomy because they believed the surgery to be a definitive solution for cancer. Surgeons advising patients with localized prostatic cancer on treatment options should address these difficult issues and provide psychological support, either themselves or in collaboration with professionals.

 Background: Open globe injury (OGI) is a common cause of unilateral visual loss in all age groups.


Objectives: To describe and identify clinical characteristics, prognostic factors and visual outcome in a group of patients with OGI in southern Israel.

Methods: We conducted a retrospective review of all cases of OGI examined in the ophthalmology department at Soroka University Medical Center, Beer Sheva, Israel, from 1996 to 2005. A total of 118 eyes with OGI were detected and analyzed statistically. We recorded demographic data, cause of injury, initial visual acuity (VA), associated globe morbidity and injuries, Ocular Trauma Score (OTS), surgical procedures, postoperative complications, and final VA.

Results: The mean age of the study group was 36.1 years and included 84% males. The median follow-up was 13.3 months (range 6–66 months). The annual incidence of open globe injuries was 3.1 cases/100,000. In 84 cases (71%) the mechanism of open eye injury was laceration. Most of the injuries were work related (45%). Bilateral injury was observed in two patients. An intraocular foreign body was observed in 45 eyes (38%). Primary surgical repair was performed in 114 eyes. Six patients (5.1%) had complications with post-traumatic endophthalmitis and 12 patients (10.1%) underwent evisceration or enucleation. Clinical signs associated with poor visual outcomes included reduced initial VA, eyelid injury, and retinal detachment at presentation.

Conclusions: In our study population the most important prognostic factors in open globe injury were initial VA, eyelid injury and retinal detachment.

 Background: The insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) requires experience and is associated with a low failure rate.

Objectives: To assess the reasons given by gynecologists why they failed to insert a LNG-IUS.

Methods: We obtained data from the sole distributor in Israel that prospectively recorded these cases when contacted by gynecologists following an insertion failure.

Results: The mean rate of failed insertions was 0.95% (range 0.77–1.03%) for the 5 year study period 2006–2010. The most common reasons reported by gynecologists for LNG-IUS insertion failure were loss of sterility of the device, inability to insert the device due to a stenotic cervical canal, accidental removal of the device following a successful insertion due to hasty removal of the inserter or the use of blunt scissors, and removal of the newly inserted LNG-IUS following ultrasound evidence that it was misplaced.

Conclusions:  Gynecologists should be aware of the common pitfalls associated with insertion of an LNG-IUS. Several techniques that may aid in avoiding these mishaps are described.

 Background: Rotavirus gastroenteritis is a prevalent childhood illness rarely complicated by secondary bacterial sepsis. Although there are case reports of septicemia after rotavirus infection, there are no recent reviews on this topic.

Objectives: To add new cases of septicemia after rotavirus to the literature, review the few cases of septicemia after rotavirus that have been reported, calculate the incidence of septicemia in children hospitalized for rotavirus gastroenteritis, and discuss the characteristics of septicemia after rotavirus infection and implications for current pediatric practice.

Methods: We identified children whose illness was complicated by septicemia from among all hospitalizations at our facility for rotavirus gastroenteritis from May 1999 through May 2010. We also review the few cases reported in the English literature. 

Results: We identified two cases of septicemia from among 632 hospitalizations for rotavirus gastroenteritis in this time period, for an incidence rate of 0.32%, which is comparable to other estimates in the English literature. The typical course for cases of bacterial superinfection involves a second peak of high fever; other clinical signs are variable.

Conclusions: Septicemia after rotavirus gastroenteritis is a rare but dangerous entity. Early identification of a child developing bacterial superinfection after rotavirus, as in any case of sepsis, is of the utmost importance, as is obtaining blood cultures in a child with a rotavirus infection and a second fever spike.

 Background: Allium sativum, the active ingredient in garlic, is known to have a beneficial effect on major cardiovascular risk factors, including dyslipidemia, blood pressure, blood glucose and insulin levels. However, the data on the significance of these effects are inconsistent due to methodological limitations, especially the use of whole garlic cloves which does not allow controlled dosing of the active compound.

Objectives: To study the effects of purified allicin on the cardiovascular system.

Methods: Spontaneously hypertensive rats treated for 6 weeks with a daily dose of 80 mg/kg/day of purified allicin added to their chow were compared to control rats that were fed regular chow. Weight, systolic blood pressure (SBP), triglycerides, cholesterol, insulin and adiponectin were measured at baseline and at the end of the study.

Results: Allicin had no effect on body weight whereas it reduced SBP significantly from 190 ± 7.5 mmHg to 168 ± 5.7 (P < 0.0001) and triglyceride levels from 96 ± 25 mg/dl to 71 ± 19 (P =0.009). Allicin had no effect on plasma cholesterol, insulin and adiponectin levels.

Conclusions: Allicin lowers blood pressure and triglyceride levels in spontaneously hypertensive rats. This effect is not mediated through weight loss.
