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 explore IL-17A-producing CD3+CD4+T cells in peripheral blood of patients with persistent AR and assess the degree of atopy, eosinophil count (Eo count), and bronchial hyper-responsiveness (BHR) to methacholine.

Methods: The study involved 61 patients and 30 controls. The percentage of CD3+CD4+IL-17A+T cells in peripheral blood was measured by flow cytometry, bronchial challenges with Mch were performed, as was skin prick tests with standard inhalant allergens, and Eo count was measured. Atopic status was determined by the number of positive SPT results and wheal mean diameter.

Results: A statistically significant difference in Th17 cell percentage was found in the AR and control groups (2.59 ± 1.32% and 1.24 ± 0.22% respectively, P = 0.001). Forty-one patients (67.2%) were polysensitized to indoor and outdoor allergens, while 20 (32.8%) had positive skin prick tests to indoor allergens. CD4+T cells were significantly higher in the patient group compared to the control group (2.91 ± 1.5% versus 1.91 ± 0.62%, P = 0.005), as was Eo count (4.48 ± 2.13 vs. 2.32 ± 1.83) (P = 0.0001). Forty-one in the AR group (67%) and 7 (23%) in the control group were Mch-positive (P = 0.001). The percentage of IL-17A-producing CD4+T cells was significantly higher in males compared to females (3.15 ± 1.8% versus 2.31 ± 0.9%, P = 0.02)

Conclusions: Polysensitized AR patients exhibited higher IL-17A-producing CD4+T cell levels and eosinophil counts. Male patients displayed a higher frequency of IL-17A-producing T cells. 

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.

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).

Background: The "see and treat" approach, proceeding without a biopsy directly to uterine cervix conization in women diagnosed with high grade squamous intraepithelial lesion (HGSIL) on Pap smear, shortens the treatment duration, lessens patient anxiety, and reduces health care costs.

Objectives: To evaluate the level of diagnostic accuracy and the over-treatment rate in the "see and treat" versus conventional management of women diagnosed with HGSIL.

Methods: We retrospectively reviewed all women with HGSIL who had undergone the "see and treat" approach during 2001–2011 at Soroka University Medical Center. Similar cohorts, who were managed conventionally with a cervical biopsy prior to the conization, served as a comparison group.

Results: The study population consisted of 403 women: 72 (18%) had undergone the "see and treat" approach and 331 (82%) conventional management. The false positive rate was 11% for the "see and treat" group, compared to 6% for the conventional management group (P = 0.162). Similarly, no statistically significant difference was observed when comparing the positive predictive value (PPV) of high grade dysplasia diagnosed on Pap smear (PPV 88.9%) versus cervical biopsy (PPV 93.8%) (P = 0.204). Moreover, both the false positive rate and PPV remained similar in subgroups of patients, according to age, menopausal status, number of births, and colposcopy findings.

Conclusions: The accuracy level of HGSIL diagnosis on Pap smear is similar to that of high grade dysplasia on a cervical biopsy. We therefore recommend referring patients with HGSIL directly to conization. Skipping the biopsy step was not associated with significant over-treatment or other adverse effects.
