Objectives: To investigate the results of PVS after MI, according to date of completion.

Methods: PVS results were interpreted according to the mode of MI management in 801 asymptomatic patients: 301 (group I) during the period 1982–1989, 315 (group II) during 1990–1999, and 185 (group III) during 2000–2010. The periods were chosen based on changes in MI management. Angiotensin-converting enzyme (ACE) inhibitors had been given since 1990; primary angioplasty was performed routinely since 2000. The PVS protocol was the same throughout the whole study period.

Results: Group III was older (61 ± 11 years) than groups I (56 ± 11) and II (58 ± 11) (P < 0.002). Left ventricular ejection fraction (LVEF) was lower in group III (36.5 ± 11%) than in groups I (44 ± 15) and II (41 ± 12) (P < 0.000). Monomorphic VT < 270 beats/min was induced as frequently in group III (28%) as in group II (22.5%) but more frequently than in group I (20%) (P < 0.03). Ventricular fibrillation and flutter (VF) was induced less frequently in group III (14%) than in groups I (28%) (P < 0.0004) and II (30%) (P < 0.0000). Low left ventricular ejection fraction (LVEF) and date of inclusion (before/after 2000) were predictors of VT or VF induction on multivariate analysis.

Conclusions: Induction of non-specific arrhythmias (ventricular flutter and fibrillation) was less frequent than before 2000, despite the indication of PVS in patients with lower LVEF. This decrease could be due to the increased use of systematic primary angioplasty for MI since 2000. 

Objectives: To investigate the association between CAD and H. pylori infection using MPI.

Methods: This prospective study evaluated CAD positivity among consecutive patients referred to a tertiary medical center for a stress/rest MPI. All patients were tested for serum anti-H. pylori and CagA protein immunoglobulin G antibodies. The CAD-positive group included patients with ischemia and/or myocardial infarctions (MI) on a stress MPI, coronary artery bypass graft surgery (CABG) or percutaneous coronary interventions (PCI). CAD-negative subjects were defined as participants with a normal MPI, no pathological Q waves in resting ECG tracing, and no history of CAD. Both groups were compared for H. pylori and CagA seropositivity. Patients’ demographic data, risk factors for CAD, and childhood socioeconomic status were recorded.

Results: The study group consisted of 300 consecutive patients, 170 men and 130 women; 64% (110/173) CAD-positive patients and 47% (60/127) CAD-negative participants were found seropositive for H. pylori infection (P = 0.005). In the adjusted analysis, H. pylori infection was found to be associated with CAD- positive (odds ratio 1.83, 95% confidence interval 1.06–3.17, P = 0.031), and MI (fixed perfusion defects on MPI) (OR 3.36, 95%CI 1.44–7.84, P = 0.005). No association was noted with CagA positivity.

Conclusions: In patients undergoing a stress MPI, serum anti-H. pylori antibodies positivity was found to be associated with CAD, independent of traditional cardiovascular risk factors. 

Objectives: To describe a novel, hybrid technique combining SILS and conventional laparoscopy using minimal abdominal wall incisions.

Methods: Fifty patients diagnosed with symptomatic cholelithiasis were operated using two reusable 5 mm trocars inserted through a single 15 mm umbilical incision and a single 2–3 mm epigastric port. This technique was dubbed “minimal incision laparoscopic cholecystectomy” (MILC).

Results: MILC was completed in 49 patients (98%). In five patients an additional 3 mm trocar was used and in 2 patients the epigastric trocar was switched to a 5 mm trocar. The procedure was converted to CLC in one patient. Mean operative time was 29 minutes (range 18–60) and the average postoperative hospital stay was 22 hours (range 6–50). There were no postoperative complications and the cosmetic results were rated excellent by the patients.

Conclusions: MILC is an intuitive, easy-to-learn and reproducible technique and requires small changes from CLC. As such, MILC may be an attractive alternative, avoiding the cost and complexity drawbacks associated with SILS.

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.

Interventional pulmonology (IP) is the newest chapter in respiratory medicine. IP includes both diagnostic and therapeutic methods. Nanotechnology, in both instrumental engineering and optical imaging, will further advance this competitive discipline towards cell diagnosis and therapy as part of the future’s personalized medicine.

Objective: To study the mechanism of platelet function inhibition in a patient with acquired thrombasthenia.

Methods: Aggregation assays of platelets from the patient and healthy controls were performed. In addition, anti-glycoprotein (GP) IIbIIIa antibodies binding to normal platelets in the presence or absence of the patient’s serum was studied by flow cytometry.

Results: Aggregation of normal platelets in the presence of patient's plasma was inhibited four- and 2.5-fold in the presence of ADP and arachidonic acid respectively, while collagen-induced aggregation was completely abolished. Ristocetin-induced aggregation was normal. The patient's serum inhibited binding of commercial anti-glycoprotein IIbIIIa antibodies to normal platelets twofold by flow cytometry. Treatment with anti-CD20 monoclonal antibody (rituximab) normalized the patient's platelet aggregation.

Conclusions: These results suggest that the patient developed inhibitory anti-GPIIbIIIa autoantibodies that caused acquired thrombasthenia. 

Objectives: To devise a clinical classification of children diagnosed with ASD according to etiologic workup.

Methods: Children diagnosed with ASD (n=436) from two databases were divided into groups of symptomatic, cryptogenic or idiopathic, and variables within each database and diagnostic category were compared.

Results: By analyzing the two separate databases, 5.4% of the children were classified as symptomatic, 27% as cryptogenic and 67.75% as idiopathic. Among other findings, the entire symptomatic group demonstrated language delays, but almost none showed evidence for regression. Our results indicate similarities between the idiopathic and cryptogenic subgroups in most of the examined variables, and mutual differences from the symptomatic subgroup. The similarities between the first two subgroups support prior evidence that most perinatal factors and minor physical anomalies do not contribute to the development of core symptoms of autism. Conclusions: Differences in gender and clinical and diagnostic features were found when etiology was used to create subtypes of ASD. This classification could have heuristic importance in the search for an autism gene(s).

Objectives: To examine the effect of seasonality, weather and holidays on hip fracture incidence in older adults. The study population comprised 2050 patients aged 65 years or more who sustained a proximal hip fracture.

Methods: The computerized files of the patients were reviewed for trends in incidence by season, precipitation, minimum and maximum temperatures, day of the week, and certain Jewish festivals.

Results: Hip fractures were more likely to occur in the winter than in the summer (P < 0.0001). Factors that significantly correlated with hip fracture were the maximum daily temperature (r = -0.746, P = 0.005) followed by the minimum daily temperature (r = -0.740, P = 0.006) and precipitation (r = 0.329, P = 0.02). There were fewer fractures on Saturdays (the Sabbath) as compared to other days of the week (P = 0.045). Researching the incidence on Jewish festivals, we found an elevated incidence on Passover (P < 0.0001) and a reduced incidence on the Day of Atonement (Yom Kippur) (P = 0.013).

Conclusions: In older people there is an elevated incidence of proximal hip fractures during the winter and on the Jewish festivals. On weekends and on the Day of Atonement the incidence of proximal hip fractures was reduced.

Objectives: To determine whether exposure to the Holocaust from preconception to early infancy is a cause of chronic morbidity in adulthood.

Methods: This pilot study involved 70 European Jews born in countries under Nazi rule (exposed group) during the period 1940–1945 who were interviewed to determine the presence of chronic diseases. A control group of 230 Israeli-born individuals of the same descent, age, and gender distribution were extracted from the Israel National Health Interview Survey-2 (unexposed group). The prevalence of selected risk factors and chronic diseases was compared between the groups.

Results: The prevalence of cardiovascular risk factors and morbidity was significantly higher in the exposed group: body mass index (BMI) (29.06 ± 3.2 vs. 26.97 ± 4.42, P = 0.015), hypertension (62.9% vs. 43%, P = 0.003), dyslipidemia (72.9% vs. 46.1%, P < 0.001), diabetes (32.9% vs. 17.4%, P = 0.006), angina pectoris (18.6% vs. 4.8%, P = 0.001) and congestive heart failure (8.6% vs. 1.7%, P = 0.013). The prevalence of cancer (30.0% vs. 8.7% P < 0.001), peptic ulcer disease (21.4% vs. 7%, P = 0.001), headaches/migraines (24.3% vs. 12.6%, P < 0.001) and anxiety/depression (50.0% vs. 8.3%, P < 0.001) was also higher in the exposed group.

Conclusions: These results suggest that exposure to Holocaust conditions in early life may be associated with a higher prevalence of obesity, dyslipidemia, diabetes, hypertension, cardiovascular morbidity, malignancy and peptic diseases in adulthood. These findings set the stage for further research, which might define those exposed as a high risk group for chronic morbidity.
