Background: There is a growing shortage of anesthesiologists practicing in Israel. This shortage is in contrast with the United States where anesthesiology has become a very desired specialty.

Objectives: To discover what factors attract Israeli students to choose a residency and how students view the option of choosing anesthesiology.

Methods: We sent questionnaires to students in the Israeli and American programs at Tel Aviv University’s Sackler Faculty of Medicine asking about factors that influenced their choice of residency and the advantages and disadvantages of a residency in anesthesiology. Although the students were studying at the same medical school and hospitals, students in the Israeli program were planning to enroll in Israeli residency programs while students in the American program planned to apply for residency in the United States.

Results: A significantly larger proportion of American students (12.9%) were interested in an anesthesiology residency when compared with the Israeli students (0%) (P = 0.034). American students considered salary and working conditions to be advantages of the anesthesiology residency while Israeli students considered Israeli working conditions and salaries to be a disadvantage.

Conclusions: Whereas there is considerable interest among American students at Sackler Medical School in an anesthesia residency, there is little interest among Israeli students.
 

Background: Obstruction of urine outflow can result from mechanical blockade as well as from functional defects. In adults, urinary tract obstruction is due mainly to acquired defects, such as pelvic tumors, calculi, and urethral stricture. In childhood it is mostly due to congenital malformations. In this article we present two rare cases of acute obstructive renal failure that presented with hydronephrosis. These cases underline the wide range of causes that may lead to this clinical feature. 

Background: High sensitivity C-reactive protein, a marker of inflammation, has been proposed to stratify coronary artery disease risk and is lowered by HMG-CoA reductase (statin) therapy. However, the reproducibility of persistently elevated hs-CRP[1] levels and association with other markers of inflammation in patients with stable CAD[2] on aggressive statin therapy is unknown.

Objectives: To determine the reproducibility of hs-CRP levels measured within 2 weeks in patients with documented CAD with stable symptoms and to identify associations with other markers of inflammation.

Methods: Levels of hs-CRP were measured twice within 14 days (7 ± 4) in 23 patients (22 males and 1 female, average age 66 ± 10 years) with stable CAD and hs-CRP ≥ 2.0 mg/L but ≤ 10 mg/L at visit 1. All patients had received statins for cholesterol management (low density lipoprotein-cholesterol 84 ± 25 mg/dl) with no dose change for > 3 months. None had a history or evidence of malignancy, chronic infection or inflammation, or recent trauma. There was no change in medications between visits 1 and 2, and no patient reported a change in symptoms or general health during this interval. White blood cell count and pro- and anti-inflammatory cytokines were measured at both visits.

Results: hs-CRP levels tended to be lower at visit 2 (median 2.4 mg/L, range 0.8–11 mg/L) than at visit 1 (median 3.3 mg/L, range 2.0–9.7 mg/L; P = 0.1793). However, between the two visits hs-CRP levels decreased by more than 1.0 mg/L in 10 patients and increased by more than 1.0 mg/L in 4 patients. Changes in hs-CRP levels were unrelated to changes in levels of white blood cells (P = 0.4353). Of the cytokines tested, only the anti-inflammatory cytokine interleukin-1 receptor antagonist and the pro-inflammatory cytokine interleukin-8 were above lower limits of detection, but there were no correlations between changes in these values and changes in hs-CRP (both P > 0.5).

Conclusions: In stable CAD patients on aggressive statin therapy, hs-CRP levels may fluctuate over brief periods in the absence of changes in health, cardiac symptom status and medications, and without corroboration with other measures of inflammation. Accordingly, elevated hs-CRP levels should be interpreted with caution in this setting.

Experimental and clinical data suggest a causal relationship between immunological and inflammatory processes and heart failure. Inflammatory processes may be involved in the pathogenesis of heart failure and may play a role in the progression of ventricular dysfunction. In the last decade several immunological methods were developed that tried to address these questions and overcome the inflammatory and immunological insults. We hope that the present review will increase awareness of new treatment options and encourage researchers and physicians to investigate this novel approach to treat patients with heart failure.
 

Ten years ago we published a review updating current knowledge on heart failure. We summarized that heart failure is a neuro-humoral and inflammatory syndrome, and that pro-inflammatory cytokines are involved in cardiac depression and in the complex syndrome of heart failure. We suggested that understanding the involvement of these cytokines may enable us to reverse cardiac depression and heart failure. Now we know that there are several mechanisms involved in this syndrome, including inflammation, nitric oxide-dependent pathways, apoptosis, reactive oxygen species, and mitochondrial energy metabolism. This review will focus on the up-to-date mechanistic aspects of heart failure, including clinical trials that have contributed to our better understanding of this entity.

Inherited forms of proteinuria constitute a rare and heterogeneous group of diseases, the most prominent of which is glomerular dysfunction, which leads to proteinuria. Investigation of the genetic background underlying these diseases has provided significant data on the normal operation of the glomerular filter. Among the different components of the glomerulus, the podocyte slit diaphragm is considered the main source for genetically derived protein alteration, which leads in turn to proteinuria. Investigation of the different proteins revealed that the lack of nephrin and podocin is the leading cause of several inherited forms of proteinuria. It was also proposed that the lack of podocin is linked to cardiac anomalies. This review suggests that the absence of slit diaphragm proteins and the open zipper phenomenon are associated with cardiac anomalies.
