Background: Peripheral arterial occlusive disease is common in patients with chronic renal failure requiring dialysis. Despite the increasing use of endovascular revascularization for lower extremity ischemia, the success rates of treating lower extremity ischemia in this challenging population remain obscure.
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.

Background: Prolonged working hours and sleep deprivation can exert negative effects on professional performance and health.
Objectives: To assess the relationship between sleep deprivation, key metabolic markers, and professional performance in medical residents.
Methods: We compared 35 residents working the in-house night shift with 35 senior year medical students in a cross-sectional cohort study. The Epworth Sleepiness Scale (ESS) questionnaire was administered and blood tests for complete blood count (CBC), blood chemistry panel, lipid profile and C-reactive protein (CRP) were obtained from all participants.
Results: Medical students and medical residents were comparable demographically except for age, weekly working hours, reported weight gain, and physical activity. The ESS questionnaires indicated a significantly higher and abnormal mean score and higher risk of falling asleep during five of eight daily activities among medical residents as compared with medical students. Medical residents had lower high density lipoprotein levels, a trend towards higher triglyceride levels and higher monocyte count than did medical students. CRP levels and other laboratory tests were normal and similar in both groups. Among the medical residents, 5 (15%) were involved in a car accident during residency, and 63% and 49% reported low professional performance and judgment levels after the night shift, respectively.
Conclusions: Medical residency service was associated with increased sleepiness, deleterious lifestyle changes, poorer lipid profile, mild CBC changes, and reduced professional performance and judgment after working the night shift. However, no significant changes were observed in CRP or in blood chemistry panel. Larger prospective cohort studies are warranted to evaluate the dynamics in sleepiness and metabolic factors over time.

Background: Reduction of fetal number has been offered in high order multiple gestations but is still controversial in triplets. Since recent advances in neonatal and obstetric care have greatly improved outcome, the benefits of multifetal pregnancy reduction (MFPR) may no longer exist in triplet gestations.
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.

Background: Oculopharyngeal muscular dystrophy (OPMD) produced by the (GCG)13 expansion mutation in the PABPN1 gene is frequent among Uzbek Jews in Israel.
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.

Background: Eye injuries are common in sports. Sports-related eye injuries have the potential for major morbidity.
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.
