Objectives: To assess the results of endovascular revascularization for lower extremity ischemia in dialysis patients.

Methods: We conducted a retrospective review of all dialysis patients who underwent endovascular treatment for critical limb ischemia (CLI) in our institution between 2007 and 2011. Data collected included comorbidities, clinical presentation, anatomic distribution of vascular lesions, amputation and survival rates.

Results: We identified 50 limbs (41 patients). Indications included: gangrene in 22%, non-healing wounds in 45%, rest pain in 31%, and debilitating claudication in 4%. Mean follow-up was 12 months (1–51 months). Nineteen patients required amputations. Freedom from amputation at 5 years was 40%. Factors associated with amputation included non-healing wounds or gangrene (68% and 36% respectively) and diabetes (P < 0.05). The survival rate was 80% after 5 years.

Conclusions:  Despite improvement in endovascular techniques for lower extremity revascularization, the incidence of limb salvage among dialysis patients remains poor, resulting in a high rate of major amputations. 

Objectives: To evaluate if fetal reduction of triplets to twins improves outcome.

Methods: We analyzed the outcome of 80 triplet gestations cared for at Rambam Health Care Campus in the last decade; 34 families decided to continue the pregnancy as triplets and 46 opted for MFPR to twins.

Results: The mean gestational age at delivery was 32.3 weeks for triplets and 35.6 weeks for twins after MFPR. Severe prematurity (delivery before 32 gestational weeks) was experienced in 37.5% of triplets and in 7% of twins. Consequently, the rate of severe neonatal morbidity (respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage) and of neonatal death was significantly higher in unreduced triplets, as was the length of hospitalization in the neonatal intensive care unit (31.4 vs. 15.7, respectively). Overall, the likelihood of a family with triplets to take home all three neonates was 80%; the likelihood to take home three healthy babies was 71.5%.

Conclusions: MFPR reduces the risk of severe prematurity and the neonatal morbidity of triplets. A secondary benefit is the reduction of cost of care per survivor. Our results indicate that MFPR should be offered in triplet gestations.

Objectives: To describe the phenotypic and genotypic features in five Bulgarian Jewish patients, from different families, with autosomal dominant OPMD.

Methods: We performed clinical follow-up, electrodiagnostic tests and mutation detection. Blood samples were obtained after informed consent and DNA was extracted; measurement of GCG repeats in both PABPN1 alleles and sequencing of OPMD mutations were performed according to standard techniques.

Results: We identified five patients (four females), aged 58 to 71 years, with bilateral ptosis, dysphagia, dysphonia (n=3) and myopathic motor units by electromyography. In all patients we noticed proximal weakness of the upper limbs with winging scapulae in three of them. All cases shared the (GCG)13-(GCG)10 PABPN1 genotype.

Conclusions: OPMD among Bulgarian Jews is produced by a (GCG)13 expansion, identical to the mutation in Uzbek Jews and French Canadians. In addition to the classical neurological and neuro-ophthalmological features, early shoulder girdle weakness is common in Bulgarian Jewish patients; this is an unusual feature during the early stages of OPMD produced by the same mutation in other populations. We suggest that besides the disease-producing GCG expansion, additional ethnicity-related genetic factors may influence the OPMD phenotype. OPMD is a rare disease, and the identification of five affected families in the rather small Bulgarian Jewish community in Israel probably represents a new cluster; future haplotype studies may elucidate whether a founder effect occurred. 

Background: Coronary slow flow phenomenon (CSFP) is a functional and structural disease that is diagnosed by coronary angiogram.    



Objectives: To evaluate the possible association between CSFP and small artery elasticity in an effort to understand the pathogenesis of CSFP.

Methods: The study population comprised 12 patients with normal coronary arteries and CSFP and 12 with normal coronary arteries without CSFP. We measured conjugated diene formation at 234 nm during low density lipoprotein (LDL) oxidation, as well as platelet aggregation. We estimated, non-invasively, arterial elasticity parameters. Mann-Whitney non-parametric test was used to compare differences between the groups. Data are presented as mean ± standard deviation.

Results: Waist circumference was 99.2 ± 8.8 cm and 114.9 ± 10.5 cm in the normal flow and CSFP groups, respectively (P = 0.003). Four patients in the CSFP group and 1 in the normal flow group had type 2 diabetes. Area under the curve in the oral glucose tolerance test was 22% higher in the CSFP than in the normal group (P = 0.04). There was no difference in systolic and diastolic blood pressure, plasma concentrations of total cholesterol, triglycerides, high density lipoprotein, LDL and platelet aggregation parameters between the groups. Lag time required until initiation of LDL oxidation in the presence of CuSO₄ was 17% longer (P = 0.02) and homocysteine fasting plasma concentration was 81% lower (P = 0.05) in the normal flow group. Large artery elasticity was the same in both groups. Small artery elasticity was 5 ± 1.5 ml/mmHgx100 in normal flow subjects and 6.1 ± 1.9 ml/mmHgx100 in the CSFP patients (P = 0.02).

Conclusions: Patients with CSFP had more metabolic derangements. Arterial stiffness was not increased in CSFP.

Objectives: To determine the outcome of RA with respect to disease activity and the rate of remission, as measured by the DAS-28, in a real-world inception cohort.

Methods: We conducted an observational cross-sectional study of a single-center real-world inception cohort of 101 consecutive patients being treated for RA in 2009–2010 in a rheumatology outpatient clinic. Patients were managed at the discretion of the attending rheumatologist with the goal of achieving remission. DAS-28 scores were calculated and analyzed by clinical and treatment variables derived from the medical files.

Results: Mean patient age was 58.6 ± 13.4 years and mean duration of disease 10.7 ± 7.9 years. Disease remission (DAS-28 < 2.6) was achieved in 26.7% of patients and low disease activity (> 2 .6 DAS-28 < 3.2) in 17%. Monotherapy with a conventional disease-modifying anti-rheumatic drug (C-DMARD, 21% of patients at last follow-up) was associated with a significantly lower mean DAS-28 score and C-reactive protein level than combined C-DMARD treatment (79% of patients), and with shorter disease duration than combined treatment with C-DMARDs or C-DMARD(s)+biological DMARD (40% of patients). Rheumatoid factor and anti-cyclic citrullinated peptide positivity had no effect on DAS-28 scores. Time from diagnosis was inversely correlated with DAS-28 scores.

Conclusions: The achievement of low disease activity and remission in a significant portion of our inception cohort of patients with RA suggests that the treat-to-target strategy is feasible and effective in routine clinical practice. 

Objectives: To investigate the occurrence and to classify sport-related eye trauma in northern Israel.

Methods: We analyzed the records of the ophthalmology emergency department for the years 2007–2011 and classified the admissions according to type, severity of injury and demographic data.

Results: In 2% of the patients the injuries occurred during a sport activity. Most of the injuries occurred during soccer, basketball or school sport activity (74%). The majority of patients were young males.

Conclusions: Most sports-related eye injuries can be prevented with adequate eye protection.

Methods: In this retrospective multicenter open-label study we examined the efficacy and tolerability of VNS in patients in five adult and pediatric epilepsy centers in Israel. All patients had drug-resistant epilepsy and after VNS implantation in 2006–2007 were followed for a minimum of 18 months. Patients were divided into two age groups: < 21 and > 21 years old.

Results: Fifty-six adults and children had a stimulator implanted in 2006–2007. At 18 months post-VNS implantation, none of the patients was seizure-free, 24.3% reported a reduction in seizures of ≥ 75%, 19% reported a 50–75% reduction, and 10.8% a 25–50% reduction. The best response rate occurred in patients with complex partial seizures. Among these patients, 7 reported a ≥ 75% reduction, 5 patients a 50–75% reduction, 3 patients a 25–50% reduction, and 8 patients a < 25% reduction. A comparison of the two age groups showed a higher reduction in seizure rate in the older group (< 21 years old) than the younger group.

Conclusions: VNS is a relatively effective and safe palliative method for treating refractory epilepsy in both adults and children. It is an alternative treatment for patients with drug-resistant epilepsy, even after a relatively longed disease duration, who are not candidates for localized epilepsy surgery.

Objectives: To evaluate in a randomized control trial whether uninterrupted administration of angiotensin II (AngII) blockade medications influence estimated glomerular filtration rate (eGFR) in patients undergoing non-emergent coronary angiography.

Methods: Patients receiving treatment with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARB) were recruited consecutively. The enrolled subjects were randomized into three groups at a 1:1:1 ratio: group A (ACE/ARB stopped 24 hours prior to the procedure and restarted immediately after the procedure), group B (ACE/ARB stopped 24 hours prior to the procedure and restarted 24 hours after the procedure), and group C (ACE/ARB continued throughout the study period). Plasma creatinine was measured and eGFR was calculated according to the Cockroft-Gault equation before and 48 hours after the coronary angiography. The primary endpoint was a change in eGFR at 48 hours.

Results: Groups A, B and C comprised 30, 31 and 33 patients respectively. The mean age of the study population was 65 ± 12 years and 67% were males. Fifty percent of the subjects had diabetes mellitus. The primary endpoint analysis showed that at 48 hours after the procedure there was no difference in ΔeGFR between groups A and C (4.25 ± 12.19 vs. 4.65 ± 11.76, P = 0.90) and groups B and C (3.72 ± 17.42 vs. 4.65 ± 11.76, P = 0.82). In post-hoc analysis the patients were clustered according to the following groups: medical alternation (group A and B) versus control (group C) and to baseline eGFR ≥ 60 ml/min vs. eGFR < 60 ml/min. In patients with baseline eGFR < 60 ml/min the ΔeGFR (baseline eGFR-eGFR 48 hours post-angiography) was significantly different between the intervention vs. control group (median 5.61 vs. median -2.19, P = 0.03 respectively). While in patients with baseline eGFR ≥ 60 ml/min there was no significant difference in ΔeGFR between the intervention and control groups.

Conclusions: ACE-I and ARB can safely be used before and after coronary angiography in patients with eGFR ≥ 60 ml/min.
