Objectives: To validate and evaluate the reliability and realism of incorporating simulation-based OSCE into the Israeli Board Examination in Anesthesia.

Methods: Validation was performed before the exam regarding Content Validity using the modified Delphi technique by members of the Task Force of the Israeli Board Examination Committee in Anesthesiology.

Results: The examination has been administered six times in the past 3 years to a total of 145 examinees. The pass rate ranged from 62% (trauma) to 91% (regional anesthesia). The mean inter-rater correlations for the total score (all items), for the Critical checklist items score, and for the Global (General) rating were 0.89, 0.86 and 0.76, respectively. The inter-correlations between the five OSCE stations scores were significant (P < 0.01) only between Trauma & Ventilation for the Total score (r = 0.32, n=63), and between Resuscitation & Regional and OR-crisis for the Global score (r = 0.42 and 0.27, n=64 and 104, respectively). The correlation between the OSCE examination score and the success rate at each of the eight different clinical domains of the oral board examination did not reach statistical significance. Most participants (70–90%) found the difficulty level of the examination stations reasonable to very easy. All major errors, which were identified in the initial two exam periods, disappeared later in the next two exam periods.

Conclusions: The exam has gradually progressed from being an optional part of the oral board examination to a prerequisite component of this test. Other anesthesiology programs or medical professions can adopt the model described here.

The plight and fate of German Jewish pediatricians during the Nazi period in Europe has not received much attention, yet the narratives of the victims still resonate today and they deserve to be remembered. The stories of two women serve as examples of the fateful turns taken by the lives of many German Jewish pediatricians between 1933 and 1945. The two women, Dr. Luci Adelsberger and Dr. Lilli Jahn, illustrate both the ordeals endured, and disparate ways the Nazi policies ultimately spared or ended lives.

Background: Q fever is endemic in Israel, yet a large series describing the clinical spectrum of inpatients with acute Q fever in Israel is lacking. 

Objectives: To report on the clinical characteristics and outcome of hospitalized patients with acute Q fever in Israel. 

Methods: We conducted a retrospective study of 100 patients hospitalized in six medical centers, in whom acute Q fever was diagnosed by the presence of immunoglobulin G and M antibodies to phase II Coxiella burnetti antigens. 

Results: The mean age of the patients was 42.7 ± 17.3 years with a male to female ratio of 1.6:1. Acute Q fever occurred throughout the year but was more common during the warm season. The most common clinical presentation was acute febrile disease (98%, mean length of fever 15.5 ± 8.6 days), followed by hepatitis (67%) and pneumonia (32%). The prominent laboratory findings included: accelerated erythrocyte sedimentation rate, normal or low white blood count with many band forms, thrombocytopenia, and abnormal urinalysis. Although the diagnosis of acute Q fever was not known during the hospitalization in the majority of patients, about 80% of our patients received appropriate antibiotic therapy and all patients recovered. 

Conclusions: Patients with acute Q fever present with a typical clinical picture that enables clinical diagnosis and empiric therapy in most cases. The prognosis of hospitalized patients with acute Q fever is excellent.

The Ink4a-Arf locus, which encodes two distinct tumor suppressor proteins, is inactivated in many cancers. Whereas p16^Ink4a is an inhibitor of cyclin D-dependent kinases, p19^Arf (p14^ARF in humans) antagonizes the E3 ubiquitin protein ligase activity of Mdm2 to activate p53. We now recognize that Arf functions in both p53-dependent and -independent modes to counteract hyper-proliferative signals originating from proto-oncogene activation, but its p53-independent activities remain poorly understood. Arf proteins are highly basic (> 20% arginine content, pI > 12) and predominantly localize within nucleoli in physical association with an abundant acidic protein, nucleophosmin (NPM/B23). When bound to NPM[1], Arf proteins are relatively stable with half-lives of 6–8 hours. Although mouse p19^Arf contains only a single lysine residue and human p14^ARF has none, both proteins are N-terminally ubiquitinated and degraded in proteasomes. Through as yet uncharacterized mechanisms, p19^Arf induces p53-independent sumoylation of a variety of cellular target proteins with which it interacts, including both Mdm2 and NPM. A naturally occurring NPM mutant (NPMc) expressed in myeloid leukemia cells redirects both wild-type NPM and p19^Arf to the cytoplasm, inhibits Arf-induced sumoylation, and attenuates p53 activity. Thus, ubiquitination and sumoylation can each influence Arf tumor suppressor activity.

Background: Anesthesiology is a vital specialty that permits the safe and humane performance of painful procedures. Most Israeli anesthesiologist are immigrants, while only a minimal number of Israeli medical school graduates enter the specialty. Unfortunately, the supply of immigrant physicians is declining due to falling immigration rates.

Objectives: To examine the current Israeli anesthesiology workforce and project future needs.

Methods: Demographic and professional information about Israeli hospital anesthesiologists was solicited from anesthesiology department heads. Data were also gathered about the past, present and projected future growth, age distribution and birth rate of the Israeli population. Needs and demand-based analyses were used to project future anesthesiology workforce requirements.

Results: Data about 711 anesthesiologists were obtained from 30 hospital anesthesiology department heads. Eighty-seven anesthesiologists (12.2%) graduated from Israeli medical schools and 459 (64.6%) graduated from medical schools in the former Soviet Union. Among the 154 anesthesiology residents were ≤ 40 years old, and only 13 (8.4%) graduated from Israeli medical schools There are approximately 10.8 anesthesiologists per 100,000 population. Projections for 2005–2015 revealed a need for 250–300 new anesthesiologists.
Conclusions: The anesthesiology workforce is predominantly composed of immigrants. This has vast implications for the future viability of the specialty because of the continuing reduction in immigration, the lack of interest in the specialty by Israeli medical school graduates, and the projected need for many new anesthesiologists to replace retirees and to provide care to a growing and aging population

Background: The contribution of the abnormal DNA mismatch repair system to non-small cell lung cancer tumorigenesis is controversial and has not been reported in Jewish Israeli patients. Similarly, the involvement of 3p deletions in NSCLC[1] in the same population has not been assessed.

Objectives: To assess the contribution of the DNA-MMR[2] system to NSCLC pathogenesis by analyzing microsatellite instability, and evaluate loss of heterozygosity at 3p rates in Israeli NSCLC patients.

Methods: Paired DNA from tumorous and non-tumorous tissue was extracted, and genotyping for MSI[3] determination was carried out using the five Bethesda markers and for determining LOH[4] two 3p markers were used. Genotyping was performed using polymerase chain reaction amplification and size separation on an ABI semiautomatic DNA sequencer, and the allelic patterns of tumorous and non-tumorous tissue were compared.

Results: Forty-four NSCLCs from 35 smokers and 9 non-smokers were analyzed, with 26 of the 44 (59%) at stage I disease. Using five microsatellite markers (D17S250, D5S346, D2S123, BAT-25, BAT-26) (known as Bethesda markers) for MSI determination, 6 of the 44 tumors (13.6%) exhibited MSI in at least one marker. Similarly, genotyping for LOH at chromosome 3p was performed using two markers (D3S4103, D3S1234) located at 3p14.2 l. With D3S4103, 33 of the 44 patients successfully analyzed were homozygous and therefore non-informative with respect to LOH. Using D3S1234, 33 of 36 patients (91.7%) were heterozygous, and 23 of these individuals' tumors (69.7%) displayed LOH. Unexpectedly, 4 of 33 tumors (12.1%) genotyped by D3S4103, and 16 of 36 tumors (44.5%) genotyped by D3S1234 showed a pattern of MSI, even though only one of these tumors showed a similar pattern when genotyped with the five consensus markers. Overall, 23 of 44 tumors (52.3%) demonstrated MSI on at least one marker, and 5 of these 23 tumors (21.7%) had MSI on two or more markers.

Conclusions: MSI using 3p markers and not the Bethesda markers occurs at a high rate and in early stages in Jewish NSCLC patients.

Background: The contribution of drugs and alcohol to current trauma‑related morbidity and mortality in Israel is not known. Identification of these factors in the fast-changing demographics of the Israeli population might lead to better care and, no less importantly, to targeted prevention measures.

Objectives: To determine the incidence of alcohol‑related trauma, and to specify the time of day, the cause of trauma, and the morbidity and mortality rates as compared to non-alcohol‑associated trauma in the tertiary trauma unit of a large medical center in Tel Aviv.

Methods: Data were obtained from the Israel National Trauma Registry, based on patient records in our institution (Tel Aviv Sourasky Medical Center) from January 2001 to December 2003.

Results: Of the 5,529 patients who were enrolled in the study, 170 had high alcohol blood levels (> 50 mg/dl). Patients intoxicated with alcohol had higher rates of road accident injuries (35% versus 24% non‑intoxicated) and stab wounds (29% vs. 7%). The Injury Severity Score of the alcohol‑intoxicated patients was higher (32% ³ 16 vs. 12% ³ 16). The alcohol‑intoxicated patients were more likely to be non-Jewish (34% vs. 9%), young (82% aged 15–44 years) and males (91%). Most of the alcohol‑related injuries occurred during the weekend (47%) and during evening‑late night hours (from 7 a.m. to 11 p.m.; 55%).

Conclusions: Alcohol‑associated trauma differs from non-alcohol‑associated trauma in many ways. Since the population at risk can be identified, it is important that legislative, social, enforcement and educational measures be adopted to reduce the extent of alcohol abuse and thereby improve the level of public safety.
