Background: Simulation-based medical education has become a powerful tool in improving the quality of care provided by health professionals.

Objectives: To evaluate the effect of a simulated patient-based educational program for military recruitment center physicians on the quality of medical encounters with adolescent candidates for military service.

Methods: Twelve physicians participated in an educational intervention that included a one day SP[1]-based workshop, where simulations of eight typical candidates for military service were conducted. Assessment of the physicians' performance before and after the intervention was based on questionnaires filled by 697 and 508 military candidates respectively, upon completion of their medical examination by these physicians. The questionnaire explored health topics raised by the examining physician as well as the atmosphere during the encounter. The candidates were also asked whether they had omitted important medical information during the medical encounter.

Results: Pre- and post-intervention comparison revealed significant changes in the percentages of candidates who reported that they were asked questions related to psychosocial topics: school problems – 59.7% and 68.9% (P = 0.01), protected sex – 29.6% and 36.4% (P = 0.01), mood changes – 46.9% and 52.2% (P = 0.05) respectively. Physicians were perceived as being interested in the candidates by 68.2% of the candidates before the intervention and 77.5% after (P < 0.01). The percentage of candidates who reported omitting medical information decreased from 6.6% before the intervention to 2.4% after (P < 0.01).

Conclusions: A simulated patient-based educational program for military physicians improved the quality of physician-candidate encounters. Such programs may serve as an effective instrument for training physicians to communicate with adolescents.

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.

Background: The Beer Sheva Psoriasis Severity Score is a novel instrument for the assessment of psoriasis severity, designed for use in routine clinical conditions.

Objective: To identify the main factors of the BPSS[1].

Methods: The sample used to study the BPSS comprised 70 patients with psoriasis vulgaris treated by climatotherapy at the Dead Sea. Psoriasis severity was assessed using BPSS and PASI (Psoriasis Area and Severity Index). Factor analysis was used to identify the main factors of BPSS. Internal consistency analysis was performed. Correlation matrices were generated to compare BPSS factors.

Results: Factor analysis demonstrated that BPSS included six factors that explained 74.0% of the variance as follows: patient assessment 26.0%; physician assessment 13.2%; palms and soles involvement 11.9%; genitals, nails, and pruritus 9.0%; face involvement 7.3%; and scalp involvement 6.6%. Total scale Cronbach’s alpha was 0.76; alpha for the factors ranged between 0.39 and 0.81.

Conclusion: The major factors of BPSS were identified. BPSS may be used as a comprehensive tool for measuring psoriasis severity.

Background: Rehabilitation camps can improve exercise tolerance and nutrition in cystic fibrosis patients.

Objectives: To assess weight gain, pulmonary function tests and daily symptoms in European CF[1] patients attending a rehabilitation camp at the Dead Sea, Israel.

Methods: We conducted a retrospective study assessing 94 CF patients who participated in winter camps held at the Dead Sea, Israel from 1997 to 2000. The camp program included daily physiotherapy, physical activities, and a high caloric diet. We assessed weight gain, pulmonary function tests, oxyhemoglobin saturation and daily symptoms before (pre), on departure (dep), and up to 3 months after the 3 week rehabilitation camp post). All data were analyzed by ANOVA for repetitive measurements. P < 0.05 was considered significant.

Results: Lung function tests and oxyhemoglobin saturation taken before, on departure and 3 months after camp were available for 35 patients. Forced expiratory volume in the first second (% predicted, average ± SD) improved by 8.2 ± 2.3% (pre, dep, post, P < 0.05). Oxyhemoglobin saturation mildly improved (1 ± 0.3%, pre, dep, post, P < 0.05). Forced vital capacity (% predicted) increased by 3.9 ± 1.2%, but was not significant (P = 0.19). Total body weight of 89 patients improved by 1.9 ± 0.9% during the camp time (P < 0.05, t-test), and in a group of 24 patients weight continuously increased up to 5.0 ± 1.7% at 3 months after the camp (P = 0.004, ANOVA).

Conclusions: In this attrition-limited retrospective study, European CF patients improved their pulmonary function and gained weight during and up to 3 months after a 3 week rehabilitation winter camp at the Dead Sea, Israel.

Background: Most Israeli males aged 16–17 undergo a thorough medical examination prior to recruitment into the army. During the last 50 years, extensive data have been gathered enabling a study of time trends in the prevalence of common diseases in this age group.

Objectives: To examine the current prevalence of common diseases, compare the results with those of previous cohorts, and assess the influence of the massive immigration during the 1990s.         

Methods: The health examination at the recruitment centers includes a medical history, complete physical examination, and review of medical documentation provided by the family physician. If needed, additional tests and referral to specialists are ordered. The prevalence of selected diseases and severity was drawn from the computerized database of the classification board. Two cohorts, 1992–94 and 2003–04, were examined and compared with three previous cohort studies in 1957–61, 1977–78 and 1982–84. Data were stratified according to origin and country of birth.

Results: The prevalence of asthma increased dramatically during the years from 10.2 per 1000 examinees in 1957–61 to 111.6 per 1000 examinees in 2003–04. The prevalence of tuberculosis declined and then increased from 0.6 per 1000 adolescents in 1982–84 to 2.4 per 1000 adolescents in 2003–04. The prevalence of type 1 diabetes mellitus increased from 0.2 cases per 1000 examinees in 1957–61 to 0.8 cases in 1977–78 and 1982–84 and 0.9 cases per 1000 examinees in 2003–04. The prevalence of severe heart defects and severe epilepsy declined in the last 20 years (1.4 and 1.7 cases per 1000 examinees in the 1982–84 cohort to 0.4 and 0.3 cases per 1000 examinees in the 2003–4 cohort respectively). The patterns of disease prevalence were different for immigrants: tuberculosis was more common while asthma and allergic rhinitis were less prevalent.

Conclusions: The prevalence of common diseases among adolescents in Israel has changed over the last 50 years. There is a different pattern for immigrants and for those born in Israel.
