 Background: Contrast-induced nephropathy (CIN) is one of the major causes of new-onset renal failure in hospitalized patients. Although renin-angiotensin-aldosterone system (RAAS) blocking agents are widely used among patients requiring contrast studies, data on the effect of these agents on the development of CIN are sparse and inconsistent.  

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.

 Background: Smoking is a serious health issue worldwide. Smoking trends among physicians predict similar trends in the general population. Little is known about current smoking rates among physicians.

Objectives: To investigate current smoking trends among Israeli physicians.

Methods: All practicing physicians at a tertiary university-affiliated medical center in central Israel were invited to complete a Web-based questionnaire on smoking habits and smoking-related issues via the institutional email. Findings were compared to those in the general population and between subgroups.

Results: Of the 90 responders (53 male, 88 Jewish), 54 (60%) had never smoked, 21 (23.3%) were past smokers, and 15 (16.7%) were current smokers. The rate of current smokers was lower than in the general population. The proportion of current smokers was higher among residents than attending physicians and among physicians in surgical compared to medical specialties. Past smokers accounted for 17.9% of the residents (average age at quitting 26.2 years) and 28.1% of the attending physicians (average age at quitting 33.0 years). Non-smokers more frequently supported harsh anti-smoking legislation.

Conclusions: The rate of smoking is lower in physicians than in the general population but has not changed over the last 15 years. Anti-smoking programs should particularly target physicians in surgical specialties.

Background: The number of patients treated with intravitreal injections has increased significantly over the past few years, mainly following the introduction of anti-vascular endothelial growth factor antibody intraocular medications. Bevacizumab is mostly used in this group of medications.

Objectives: To describe persistent elevation of intraocular pressure (IOP) following intravitreal injection of bevacizumab.

Methods: We reviewed consecutive cases of persistent IOP elevation after intravitreal bevacizumab injection for exudative age-related macular degeneration (AMD). A total of 424 patients (528 eyes) met the inclusion criteria and received 1796 intravitreal injections of bevacizumab. Persistent IOP elevation was found in 19 eyes (3.6%, 19/528) of 18 patients (4.2%, 18/424) with IOP elevated 30–70 mmHg, 3–30 days after injection.

Results: Mean IOP was 42.6 mmHg (range 30–70); IOP elevations occurred after an average of 7.8 injections of bevacizumab (range 3–13). Injected eyes (19/528) had a significantly higher incidence of elevated IOP than uninjected eyes (fellow eyes), 1/328, P < 0.001.

 Conclusions: Like other anti-vascular endothelial growth factor (VEGF) substances reported in a few recent studies, intravitreal injection of bevacizumab for neovascular AMD may be associated with persistent IOP elevation. Providers should be aware that significant IOP elevation might occur after repeated treatments.

 Background: The role of induction chemotherapy in advanced squamous cell carcinoma of the head and neck (SCCHN) is under constant debate. Surgery, radiotherapy, chemotherapy, and targeted therapies are part of the treatment strategy in these patients, but their sequence remains to be defined.

Objectives: To evaluate the feasibility of induction chemotherapy with docetaxel-cisplatin-5-flurouracil (TPF) followed by external beam radiotherapy (EBRT) with concomitant chemotherapy (CRT) or cetuximab (ERT) in the treatment of patients with advanced SCCHN.

Methods: We reviewed the data of all patients with advanced SCCHN, stage III and IV, treated in 2007–2010. Tolerability was assessed and scored according to the proportion of patients completing the planned study protocol. Toxicity was scored using the U.S. National Cancer Institute Common Toxicity Criteria (version 4) for classification of adverse events.

Results: The study included 53 patients. TPF was initiated at a reduced dose in 13 patients (25%). Twenty-two patients (41.5%) received primary prophylaxis with granulocyte colony-stimulating factor (GCSF) and 42 (77%) completed treatment according to schedule. During the induction phase one patient (2%) died and 24 (45%) had one or more grade 3-4 complications. The number of patients who developed neutropenia was lower in the group that received primary GCSF prophylaxis. Secondary dose reductions were required in 21% of the patients.

Conclusions: Induction TPF was associated with grade 3-4 toxicity. Prophylaxis with GCSF should be part of the treatment regimen.

 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: Hemorrhagic radiation cystitis (HRC) is a significant clinical problem that occurs after pelvic radiation therapy and is often refractory.

Objectives: To evaluate the efficacy and safety of hyperbaric oxygen therapy (HBO) for HRC.

Methods: Daily 90 minute sessions of HBO at 2 ATM 100% oxygen were given to 32 HRC patients with American Society of Therapeutic Radiology and Oncology (ASTRO) grades 3-4 hematuria.

Results: The median age was 72.5 (48–88 years). The median time interval between radiation therapy and HBO was 4 years (1–26 years). The patients received a median of 30 HBO sessions (3–53). Hematuria resolved in 27 patients (84%) and persisted in 5. Cystectomy was required in two, and ileal-conduit and bilateral percutaneous nephrostomies were performed in one and two patients, respectively. With a median follow-up of 12 months (5–74 months), the hematuria cleared completely in 16 patients (59%) and mild hematuria requiring no further treatment recurred in 10 others. Another patient with ASTRO grade 4 hematuria needed bladder irrigation and blood transfusions. Complications included eardrum perforation in four patients and transient vertigo and mild hemoptysis in one case each. None of them required HBO discontinuation.

Conclusions: HBO controlled bleeding in 84% of the patients. A durable freedom from significant hematuria was achieved in 96% of the patients. HBO seems to be an effective and safe modality in patients with HRC.

 Background: It is well known that quality of life is an integral part in the outcome evaluation process of psoriasis treatment. Very few studies, however, examined the effect of climatotherapy at the Dead Sea on quality of life of such chronically ill patients.

Objectives: To determine the effect of the Dead Sea climatotherapy on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Methods: A total of 119 patients participated in an observational prospective study carried out at the Deutsches Medizinisches Zentrum clinic, a medical skin care center specializing in climatotherapy. The patients completed questionnaires (Skindex-29) to quantify their quality of life at different time points: the day of arrival, the day of departure, and 3 and 6 months after the end of treatment.

Results: Marked improvement in the quality of life scores was measured between the time of arrival to time of departure and to 3 months after the end of treatment.

Conclusions: Dead Sea climatotherapy has a significant positive influence on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

 Background: Ethnic differences in the incidence of spitting up have not been reported. The nursing team at our well-baby nursery observed that newborn infants of Ethiopian origin appeared to spit up more than the others.

Objective: To determine whether there are such ethnic differences and what, if anything, is their clinical relevance.

Methods: Of the 3663 enrolled infants born at the Hillel Yaffe Medical Center during the 12 month study period, 55 were of Ethiopian origin and their medical records were retrospectively surveyed. The retrieved data were compared with those of 167 randomly selected non-Ethiopian newborns (controls). Exclusion criteria were preterm delivery, admission to the neonatal intensive care unit, and congenital birth defects.

Results: Newborn infants of Ethiopian origin spit up 57% more than control infants. The difference in the number of spit ups was more obvious when only the infants who spit up were compared (2.3 ± 1.7 Ethiopian newborns vs. 1.5 ± 0.9 controls, P = 0.002), although the percentage of infants who spit up was the same in the two groups. There was no difference in weight gain, days of hospitalization, bilirubin levels or nutrition type between the groups.

Conclusions: Infants of Ethiopian origin spit up more than the control newborn infants of non-Ethiopian origin, while other clinical parameters were similar. In the absence of other pathological signs, spitting up is a non-relevant clinical condition.

 Background: The use of extracorporeal membrane oxygenation (ECMO) in children after cardiac surgery is well established. ECMO support is becoming an integral tool for cardiopulmonary resuscitation in specified centers.

Objectives: To review our use of ECMO over a 10 year period.

Methods: All children supported with ECMO from 2000 to 2010 were reviewed. Most of these children suffered from cardiac anomalies. The patients were analyzed by age, weight, procedure, RACHS-1 when appropriate, length of support, and outcome.

Results: Sixty-two children were supported with ECMO; their median age was 3 months (range 0–216 months) and median weight 4.3 kg (range 1.9–51 kg). Thirty-four patients (52.3%) needed additional hemofiltration or dialysis due to renal failure. The children requiring ECMO support represented a wide spectrum of cardiac lesions; the most common procedure was arterial switch operation 27.4% (n=17). ECMO was required mainly for failure to separate from the heart-lung machine (n=55). The median duration of ECMO support was 4 days (range 1–14 days); 29 (46.7%) patients were weaned successfully from ECMO during this time period, and 5 of them died during hospitalization, yielding an overall hospital survival rate of 38.7%.

Conclusions: ECMO support has significant survival benefit for patients with post-cardiotomy heart failure. Its early deployment should be considered in cardiopulmonary resuscitation.
