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: The growing numbers of H1N1 "swine influenza" cases should prompt national health systems to achieve dual preparedness: preparedness of clinicians to recognize and treat cases of human H1N1 flu, and national preparedness for an influenza pandemic. This is similar to recent contingency planning for an avian flu pandemic.

Objectives: To evaluate hospital personnel's knowledge on avian flu (zoonotic, sporadic, pandemic), comparing among nurses, residents and faculty, and between those who attended lectures or other educational modalities targeted at avian flu and those who did not.

Methods: A 14 item multiple choice questionnaire was designed to test crucial points regarding preparedness for human avian flu. The directors of 26 general hospitals were instructed by the Ministry of Health to improve knowledge of and preparedness for different avian flu scenarios, and to expect an official inspection. As part of this inspection, we distributed the questionnaires to nurses, residents and senior physicians.

Results: Altogether, 589 questionnaires were collected from the 26 hospitals. Examinees who participated in training modules (course, lecture or any training provided by the hospital) did somewhat better (scoring 78 points out of 100) than those who did not attend the training (70 points) (P < 0.05). Differences in nurses’ knowledge were even more striking: 66 points for the non-attendants compared to 79 for nurses who attended the lecture (P < 0.05).  Residents had significantly lower scores compared to nurses or senior physicians: 70 compared to 77 and 78 respectively (P < 0.05).

Background: It is currently recommended that capillary glucose levels of non-critically ill hospitalized diabetic patients be maintained at between 140 and 180 mg/dl. Implementation of these recommendations and evaluation of their effectiveness require that data regarding the glucose control of these hospitalized patients be accessible.

Objective: To analyze glucose control and monitoring of all the diabetic patients hospitalized in the general medicine wards of our medical center.

Methods: Capillary glucose measurements of all diabetic patients hospitalized in our departments of medicine between June and December 2008 were recorded by a central computerized institutional glucometer. Median glucose values and frequency of daily glucose checks per patient were analyzed in the internal medicine wards.

Results: We evaluated 14,366 capillary measurements from 2475 patients; 43% were taken before breakfast and 25% before dinner. A median of one daily determination per patient was obtained. This number increased 1.4-fold in patients with hyperglycemia > 200 mg/dl and 2.5-fold in patients with hypoglycemia. Seventy-five percent of the recorded glucose values were within the recommended target range, with a median daily level of 161 mg/dl and median fasting glucose of 142 mg/dl. A significant variance was found between wards.

Conclusions: The frequency of capillary glucose measurements in diabetic patients hospitalized in general medicine wards was low; most capillary glucose values, however, were within the recommended target range. The optimal monitoring of glucose in these patients remains to be determined.

The features of infective endocarditis include both cardiac and non-cardiac manifestations. Neurologic complications are seen in up to 40% of patients with infective endocarditis and are the presenting symptom in a substantial percentage. We describe in detail the clinical scenarios of three patients admitted to our hospital, compare their characteristics and review the recent literature describing neurologic manifestations of infective endocarditis. Our patients demonstrate that infective endocarditis can develop without comorbidity or a valvular defect. Moreover, our patients were young and lacked the most common symptom of endocarditis: fever. The most common neurologic manifestations were focal neurologic deficits and confusion. We conclude that infective endocarditis should always be considered in patients presenting with new-onset neurologic complaints, especially in those without comorbidities or other risk factors. A prompt diagnosis should be reached and antibiotic treatment initiated as soon as possible.

Background: Guidelines are frequently under-implemented in older patients with heart failure. Octogenerians are often excluded from clinical trials.

Objectives: To characterize the clinical profile of the oldest-old (age ≥ 80 years) heart failure patients hospitalized in a subacute geriatric hospital and to evaluate their management and 1 year outcome.

Methods: Patient characteristics and in-hospital course were retrospectively collected. Diagnosis of heart failure was based mainly on clinical evaluation in addition to chest X-ray results and echocardiographic findings when available.

Results: The study population comprised 96 consecutive unselected heart failure patients hospitalized from January to June 2003. The patients were predominantly women (67%), aged 85 ± 5 years, fully dependent or frail with a high rate of comorbidities. Adherence to guidelines and recommended heart failure medications was poor. Their 1 year mortality was 57%. According to logistic regression analysis, predictors of 1 year mortality were lower body mass index (odds ratio 0.86, 95% confidence interval 0.78–0.96) and high urea levels (OR[1] 1.04, 95% CI[2] 1.02–1.06).

Conclusions: Our study confirms that the management of oldest-old heart failure patients hospitalized in a subacute geriatric hospital was suboptimal and their mortality was exceptionally high.

Background: Kidney disease and cardiovascular disease seem to be lethally synergistic and both are approaching the epidemic level. A reduced glomerular filtration rate is associated with increased mortality risk in patients with heart failure. Many patients with congestive heart failure are anemic. Anemia is very often associated with chronic kidney disease.

Objectives: To assess – in relation to New York Heart Association class – the prevalence of anemia and chronic kidney disease in patients with normal serum creatinine in a cohort of 526 consecutive patients with coronary artery disease undergoing percutaneous coronary interventions.

Methods: GFR[1] was estimated using the simplified MDRD formula, the Cockcroft-Gault formula, the Jeliffe and the novel CKD-EPI formula.

Results: According to the WHO definition the prevalence of anemia in our study was 21%. We observed a progressive decline in GFR and hemoglobin concentration together with a rise in NYHA[2] class. Significant correlations were observed between eGFR[3] and systolic blood pressure, diastolic blood pressure, age, NYHA class, complications of PCI[4], including bleeding, and major adverse cardiac events.

Conclusions: The prevalence of anemia and chronic kidney disease is high in patients undergoing PCI despite normal serum creatinine, particularly in higher NYHA class. Lower eGFR and hemoglobin are associated with more complications, including bleeding after PCI and higher prevalence of major adverse cardiac events. In patients with risk factors for cardiovascular disease, GFR should be estimated since renal dysfunction and subsequent anemia are important risk factors for cardiovascular morbidity and mortality.

Background: Clinical and epidemiologic features of coronary heart disease may not be explained solely by established risk factors. The role of infectious pathogens in the development and rupture of atherosclerotic plaques remains elusive but an association between Chlamydia pneumoniae, Mycoplasma pneumoniae and CHD[1] has been previously reported

Objectives: To determine whether there is an association between mycoplasmal infections and CHD.

Methods: We conducted a prospective cohort analysis of 150 consecutive hospitalized patients with CHD (85 with acute coronary syndrome and 65 admitted for unrelated reasons) and 98 healthy blood donors. Antibody titers for Mycoplasma pneumoniae, M. fermentans, M. hominis and Ureaplasma urealyticum were measured with the agglutination test or specific enzyme-linked immunosorbent assay in all three groups of patients.

Results: Analysis of the antibody titers did not reveal any significant difference in the presence of mycoplasmal antibodies between the patients with ACS[2], patients with known stable CHD hospitalized for non-CHD reasons, and healthy blood donors.

Conclusions: Determination of specific antibodies did not reveal a significant association among different types of mycoplasmal infection and CHD.

Background: Continuous use of combined oral contraceptives is currently attracting growing interest as a means of improving menstrual related symptoms and reducing the number of bleeding days.

Objectives: To evaluate bleeding patterns, menstrual symptoms and quality of life with an extended 84/7 oral contraceptive regimen versus 21/7 cycles.

Methods: In two consecutive run-in cycles, 30 µg ethinyl estradiol and 3 mg drospirenone tablets taken on days 1–21 were followed by a tablet-free period from days 22 to 28 of each cycle and then by two 84 day cycles of pill use with a 7 day tablet-free interval. The primary outcome was the total number of bleeding/spotting days. Secondary outcomes were severity of daily symptoms, general well-being determined by the PGWBI questionnaire, and overall treatment satisfaction.

Results: Of the 137 women invited to participate in the study 109 (aged 18–40 years) were enrolled. The number of bleeding days decreased by about one-third from a calculated 31.8 days of bleeding under a cyclic 21/7 regimen to an expected total of 21.8 days for the extended 84/7 regimen. The incidence of menorrhagia, intermenstrual bleeding, dysmenorrhea, abdominal bloating, breast tenderness, depressive moods and irritability – when compared at enrollment and at the end of the second extended study period – was significantly lower (P < 0.005) among women on the continuous pill regimen. The median (range) global PGWBI scores were not substantially different before and after the extended use cycles: 78.2 (39.1–96.4) and 77.3 (30.9–96.4), respectively. Body weight and skin condition also remained constant. At the completion of the study: 65.5% of the women were either highly satisfied (41.4%) or satisfied (24.1%) with the extended regimen.

Conclusions: The extended 84/7 regimen was found to be satisfactory for the majority of participants and was associated with a decrease in the number of bleeding days and an improvement in menstrual symptoms compared to 21/7 cycles. 

Background: There is controversy as to which is the preferred treatment for distal radius intra-articular fractures – anatomic reduction or external fixation.

Objectives: To evaluate the radiologic and functional outcome following external fixation of these fractures.

Methods: Between January 2003 and March 2005, 43 patients with distal radius intra-articular fractures were treated using a mini-external AO device. Follow-up of 38 of the patients included X-rays at 1 week, 6 weeks and 6 months postoperatively. The Visual Analogue Scale was used to assess pain levels, and the Lidstrom criteria scale to evaluate functional outcome and wrist motion. Clinical and radiographic results were correlated.

Results: According to the Lidstrom criteria, the results were excellent in 31%, good in 61% and fair in 5.5%; 2.5% had a poor outcome. The results of the VAS[1] were good. Thirty-five patients gained a good range of wrist movement, but 3 had a markedly reduced range. We found statistical correlation between the radiographic and clinical results, emphasizing the value of good reduction. There was no correlation between fracture type (Frykman score) and radiologic results or clinical results.

Conclusions: External fixation seems to be the preferred method of treatment for distal radius intra-articular fractures, assuming that good reduction can be achieved. The procedure is also quick, the risk of infection is small, and there is little damage to the surrounding tissues.
