Background: There is scant research on the psychopathology of Israeli soldiers who present to a general hospital emergency department (ED).

Objectives: To assess the psychopathology among a cohort of Israeli soldiers who presented to a general hospital ED for mental health assessment.

Methods: The demographic and clinical characteristics of 124 consecutive soldiers who presented to the ED for psychiatric assessment between January 2008 and September 2012 were reviewed. Twenty-seven soldiers from the cohort were contacted for follow-up by telephone on average 52 months later.

Results: The reasons for presentation to the ED, usually during the early stages of military service, included self-harming behavior, suicidal ideation, somatoform complaints, and dissatisfaction with their military service. Psychiatric diagnoses included adjustment disorder and personality disorder. Self-harming behavior/suicidal ideation was significantly correlated with unspecified adjustment disorder (P = 0.02) and personality disorder (P = 0.001). At follow-up, there was a lack of substantial psychopathology: none of the subjects engaged in self-harming behavior/suicidal ideation and a consistent trend was observed toward clinical improvement.

Conclusions: Psychiatric intervention of soldiers who present to a general hospital ED because of emotional difficulties may provide the opportunity for crisis intervention and validation of the soldier's distress. To the best of our knowledge this is the first Israeli study of psychopathology among soldiers who presented to an ED.

Background: Skin colonization of microorganisms in blood cultures (BCs) are generally considered clinically non-significant and can be the source of a true infection, particularly in immunosuppressed patients.

Objectives: To study the epidemiology and risk factors for bacteremia caused by contaminants.

Methods: This retrospective, descriptive study is based on adult BCs collected (2004–2013) and categorized as positive (True bacteremia [TrueB] or contamination) or negative. Clinical, demographic, and laboratory characteristics of BCs positive for the six most common potential contaminant pathogens (PCPs) that can cause TrueB and contamination (Coagulase-negative Staphylococcus [CoNS], Streptococcus viridans, Propionibacterium acnes, Corynebacterium spp., Bacillus spp., Clostridium spp.) were assessed. Ninety-two TrueB were identified vs. 196 contaminations (1:2 ratio).

Results: From 74,014 BCs, PCPs were found in 3735 samples, of which 3643 (97.5%) were contaminations and 92 (2.5%) were TrueB. The overall rate of BC contamination decreased during the study period from 6.7% to 3.8%. CoNS was the most common PCP. Bacillus spp. were only contaminants. Clostridium spp. and Streptococcus viridans were more often TrueB. In a multivariate model, predictors of TrueB included high creatinine levels, Streptococcus viridans in BC, and multiple positive BCs. A single culture of CoNS was strongly predictive of contamination.

Conclusions: Ten years of data on BCs, focusing on six PCPs, demonstrates a significant, yet insufficient reduction in the rate of contamination. High creatinine level, isolation of Streptococcus viridans, and multiple positive BCs were predictors of TrueB, while growth of CoNS was strongly predictive of contamination. This model could assist in diagnostic and therapeutic decision making.

Background: Chronic kidney disease (CKD) is often accompanied by impairment of cardiac function that may lead to major cardiac events. Erythropoietin (EPO), a kidney-produced protein, was shown to be beneficial to heart function. It was suggested that reduced EPO secretion in CKD may play a role in the initiation of heart damage. 

Objectives: To investigate molecular changes in the EPO/erythropoietin receptor (EPO-R) axis in rat cardiomyocytes using a rat model for CKD.

Methods: We established a rat model for CKD by kidney resection. Cardiac tissue sections were stained with Masson’s trichrome to assess interstitial fibrosis indicating cardiac damage. To evaluate changes in the EPO/EPO-R signaling cascade in the myocardium we measured cardiac EPO and EPO-R as well as the phosphorylation levels of STAT-5, a downstream element in this cascade.

Results: At 11 weeks after resection, animals presented severe renal failure reflected by reduced creatinine clearance, elevated blood urea nitrogen and presence of anemia. Histological analysis revealed enhanced fibrosis in cardiac sections of CKD animals compared to the sham controls. Parallel to these changes, we found that although cardiac EPO levels were similar in both groups, the expression of EPO-R and the activated form of its downstream protein STAT-5 were significantly lower in CKD animals.

Conclusions: CKD results in molecular changes in the EPO/EPO-R axis. These changes may play a role in early cardiac damage observed in the cardiorenal syndrome.

 

Chikungunya fever (CHIK-F) has been increasingly documented among Western travelers returning from areas with chikungunya virus transmission, which are also popular tourist sites.  We present three Israeli travelers who developed fever, maculopapular rash and long-standing arthralgias while visiting northern Indian states not known to be involved in the chikungunya fever epidemic. We also present an epidemiological review of the chikungunya epidemic over the past decades. Rare systemic manifestations of this disorder, like catastrophic antiphospholipid syndrome (CAPS) and adult onset still’s syndrome, are discussed. The present era of international travel poses a novel diagnostic and epidemiologic challenge and we must increase our awareness to the possibility of an exotic tropical infectious disease.

Background: Anal cancer is a relatively uncommon disease, accounting for only 4% of cancers of the lower gastrointestinal tract. 

Objectives: To summarize the single-center experience in the treatment of anal carcinoma using various radiation techniques.

Methods: We conducted a retrospective chart review of consecutive patients who were treated for anal cancer between the years 2002 and 2011. The data extracted included demographics, type of radiation technique, treatment-associated acute toxicity, and patterns of failure and survival. For statistical analysis purposes, the patients were divided into two groups according to radiotherapy technique: 2D (group A) and 3D (group B).

Results: A total of 42 patients – 25 (59.5%) females and 17 males (40.5%) – underwent definitive chemo-radiation treatment (CRT) for anal cancer. Group A comprised 26 patients and group B 14 patients. Toxicity did not differ significantly between the groups, only in grade 1-2 skin toxicity which was more common in group B. There were significant differences in the unplanned interruptions in treatment, in both the number of patients who needed a treatment break and the number of days needed (more in group A). There were no differences in treatment response and patterns of failure between these two techniques, or in overall survival between the two groups. 

Conclusions: Our study results are consistent with reported large randomized trials, indicating that current treatments for anal carcinomas are associated with high grade acute toxicity that may result in significant treatment interruptions. The 2D technique was associated with significantly more treatment interruptions, but did not differ from 3D with regard to treatment efficacy. 

 

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: The role of alcohol in driver fatalities in Israel is unknown, and monitoring blood alcohol concentration among drivers is not routine. Moreover, over the past decade, self-reported access to and consumption of alcohol in Israel has been on the rise.

Objectives: To use available data to characterize alcohol-related driver fatalities.

Methods: The prevalence of alcohol-related driver fatalities were estimated for 443 drivers, ages 17+ years using data from Israel's National Center for Forensic Medicine for 2000–2004.

Results: Between 8% and 17% of driver fatalities had a BAC[1] ≥ 0.05 g/dl. Most drivers with alcohol exceeding this level were males aged 21–30 years who died on weekends. Recreational and/or medicinal drugs were found in 6%–11% of driver fatalities. Mean BAC among driver fatalities with BAC ≥ 0.05 g/dl was threefold higher than the legal driving limit and appears to be increasing with time.

Conclusions: In light of the evidence suggesting an increasing mean BAC over time as well as reported increasing trends in access to alcohol and consumption, this study should serve as a basis for future research to comprehensively characterize the extent of this problem
