Objectives: To evaluate the retention of CPR skills and confidence in delivering CPR by preclinical medical students.

Methods: A questionnaire and the Objective Structured Clinical Examination (OSCE) were used to assess confidence and CPR skills among preclinical, second and third-year medical students who had passed a first-aid course during their first year but were not retrained since.

Results: The study group comprised 64 students: 35 were 1 year after training and 29 were 2 years after training. The groups were demographically similar. Preparedness, recollection and confidence in delivering CPR were significantly lower in the 2 years after training group compared to those 1 year after training (P < 0.05). The mean OSCE score was 19.8 ± 5.2 (of 27) lower in those 2 years post- training than those 1 year post-training (17.8 ± 6.35 vs. 21.4 ± 3.4 respectively, P = 0.009). Only 70% passed the OSCE, considerably less in students 2 years post-training than in those 1 year post-training (52% vs. 86%, P < 0.01). Lowest retention was found in checking safety, pulse check, airway opening, rescue breathing and ventilation technique skills. A 1 year interval was chosen by 81% of the participants as the optimal interval for retraining (91% vs. 71% in the 2 years post-training group vs. the 1 year post- training group respectively, P = 0.08).

Conclusions: Confidence and CPR skills of preclinical medical students deteriorate significantly within 1 year post-training, reaching an unacceptable level 2 years post-training. We recommend refresher training at least every year.

Objectives: To characterize the clinical features and outcomes of body packers hospitalized at the Sheba Medical Center.

Methods: We conducted a retrospective case series of body packers hospitalized between January 2010 and October 2012 in our medical center. Electronic medical records and imaging files were reviewed to extract clinical, laboratory and radiological data as well as details on medical treatments.

Results: We identified 23 body packers (mean age 38 ± 10 years), 20 of whom smuggled cocaine from South America. The number of packets transported ranged from 1 to 242 (median 42) and duration of hospitalization from 1 to 14 days (median 2). Two subjects required surgical intervention. All others were treated conservatively by polyethylene glycol-electrolyte lavage solution, laxatives, or watchful waiting. Ten patients underwent a urinary screen for illicit drugs, 7 of whom tested positive for cocaine and 2 for cannabinoids. Abdominal X-rays were performed in all patients at admission, and 14 had follow-up imaging, including abdominal CT scans without contrast media in 8.

Conclusions: The main treatment goals for body packers are the rapid excretion of drug packets and early detection of complications, i.e., drug intoxication and bowel obstruction. We suggest the use of a structured treatment approach for the in-hospital management of body packers.

Objectives: To present the feasibility and safety of DSMR in Israel.

Methods: Thirty patients with suspected or known CAD were studied. DSMR images were acquired during short breath-holds in three short axis views and four-, two-, and three-chamber views. Patients were examined at rest and during a standard dobutamine-atropine protocol. Regional wall motion was assessed in a 16-segment model and the image quality was evaluated using a four-point scale for the visibility of the endocardial border.

Results: In 28 patients (93.4%) DSMR was successfully performed and completed within an average of 55 ± 6 minutes. One patient could not be examined because of claustrophobia and another patient, who was on beta-blockers, did not reach the target heart rate. Image quality was excellent and there was no difference between the rest and stress images in short axis (3.91 ± 0.29 vs. 3.88 ± 0.34, P = 0.13, respectively) and long axis (3.83 ± 0.38 vs. 3.70 ± 0.49, P = 0.09, respectively) views. Segmental intra-observer agreement for wall motion contractility at rest and stress cine images was almost perfect (κ = 0.88, 95% confidence interval = 0.93–0.84, and κ = 0.82, 95% CI = 0.88–0.76) respectively. No serious side effects were observed during DSMR.

Conclusion: The present study confirms the feasibility, safety and excellent image quality of DSMR for the diagnosis of coronary artery diseases.

Objectives: To assess the reasons given by gynecologists why they failed to insert a LNG-IUS.

Methods: We obtained data from the sole distributor in Israel that prospectively recorded these cases when contacted by gynecologists following an insertion failure.

Results: The mean rate of failed insertions was 0.95% (range 0.77–1.03%) for the 5 year study period 2006–2010. The most common reasons reported by gynecologists for LNG-IUS insertion failure were loss of sterility of the device, inability to insert the device due to a stenotic cervical canal, accidental removal of the device following a successful insertion due to hasty removal of the inserter or the use of blunt scissors, and removal of the newly inserted LNG-IUS following ultrasound evidence that it was misplaced.

Conclusions:  Gynecologists should be aware of the common pitfalls associated with insertion of an LNG-IUS. Several techniques that may aid in avoiding these mishaps are described.

Objectives: To assess opioid use during a 6 year period (2001–2006) among cancer patients served by Clalit Health Services, the largest health management organization in Israel.

Methods: Purchasing data of opioids authorized for use in Israel were obtained from the computerized databases of Clalit for the period 2001–2006. Patients' demographic and cancer morbidity data were extracted. The data were analyzed by translating the purchased opioids (fentanyl patch, oxycodone, buprenorphine, methadone, hydromorphone) to oral morphine equivalents (OME).

Results: During the study period 182,066 Clalit members were diagnosed with cancer; 58,443 (32.1%) of them died and 31,628 (17.3%) purchased opioids at least once. In 2001, 7.5% of Clalit cancer patients purchased opioids at least once within 5 years of the initial diagnosis. Between 2002 and 2006 this percentage increased consistently, reaching 9.9% in 2006. The average daily dose of opioids increased from 104.1 mg OME in the year 2001 to 115.2 mg OME in 2006 (11% increase). The average duration of opioid purchasing was 5.0 ± 8.3 months (range 1–84 months, median 2). During the study period 19,426 cancer patients who purchased opioids at least once died; only 14.3% (3274) were still alive 2 years after their first opioid prescription.

Conclusions: Opioid purchasing increased during the study period, especially during the final months of life. Children (0–18 years old) and elderly male patients (≥ 65 years) began opioid treatment later compared to other age groups. Only a few patients had an opioid early enough to relieve their pain. 

Objectives: To investigate the reasons for non-adherence associated with cardiovascular risk factors among Bedouins.

Methods: We identified Bedouin patients with HTN, DM or LMD from medical records and randomly selected 443 high adherent and 403 low adherent patients. Using trained interviewers we conducted in-depth structured interviews regarding knowledge and attitudes to chronic illness and its treatment, health services evaluation, and socio-demographic factors.

Results: The study population included 99 high and 101 low adherent patients. More low adherent patients agreed that traditional therapy can replace prescribed medications for DM, HTN or LMD (47% vs. 26%, P < 0.01), and 10% used only traditional medications. Also, more low adherent patients believed that the side effects of prescribed drugs are actually worse than the disease itself (65% vs. 47%, P < 0.05), and 47% cited this as a reason for discontinuing drug treatment (47% vs. 31%, P < 0.05).

Conclusions: Our findings suggest that in this minority population the basis for non-adherence derives directly from patients' perceptions of chronic disease and drug treatment. A focused intervention should emphasize the importance of early evidence-based drug therapy with open patient-physician dialogue on the meaning of chronic disease and the side effects of prescribed drugs.

Background: Determining the prognosis of patients with heart failure is essential for patient management and clinical trial conduct. The relative value of traditional prognostic criteria remains unclear and the assessment of long-term prognosis for individual patients is problematic.

Objectives: To determine the ability of clinical, hemodynamic and echocardiographic parameters to predict the long-term prognosis of patients with idiopathic dilated cardiomyopathy.

Methods: We investigated the ability of clinical, hemodynamic and echocardiographic parameters to predict the long-term prognosis of individual patients in a large, representative, contemporary cohort of idiopathic dilated cardiomyopathy (IDCM) patients referred to Johns Hopkins from 1997 to 2004 for evaluation of cardiomyopathy. In all patients a baseline history was taken, and physical examination, laboratory studies, echocardiogram, right heart catheterization and endomyocardial biopsy were performed.

Results: In 171 IDCM patients followed for a median 3.5 years, there were 50 long-term event-free survivors (LTS) (median survival 6.4 years) and 34 patients died or underwent ventricular assist device placement or transplantation within 5 years (NLTS; non-long-term survivors) (median time to event 1.83 years. Established risk factors (gender, race, presence of diabetes, serum creatinine, sodium) and the use of accepted heart failure medications (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta blockers) were similar between the two groups. Although LTS had younger age, higher ejection fraction (EF) and lower New York Heart Association (NYHA) class at presentation, the positive predictive value of an EF< 25% was 64% (95% CI 41%–79%) and of NYHA class > 2 was 53% (95% CI 36–69%). A logistic model incorporating these three variables incorrectly classified 29% of patients.

Conclusions: IDCM exhibits a highly variable natural history and standard clinical predictors have limited ability to classify IDCM patients into broad prognostic categories. These findings suggest that there are important host-environmental factors still unappreciated in the biology of IDCM.
 

Current treatments for systemic lupus erythematosus (SLE) are effective in reducing morbidity and mortality but are not specific and have severe adverse effects. Based on understanding of the different dysregulated immunological pathways involved in SLE pathogenesis, specific targeted therapies were developed. This review presents the current and the near-future novel biological immune targeted treatments, such as B cell-targeted therapy, cytokine blockade, peptide-based treatments and other novel treatments for SLE.
 

Background: Establishing the etiology of a large pericardial effusion is of crucial importance since it is likely the result of a serious underlying disease. However, there is a paucity of literature on the diagnostic management of patients with large hemorrhagic effusions.

Objectives: To analyze the management of patients with large hemorrhagic pericardial effusion.

Methods: We reviewed seven cases of large hemorrhagic pericardial effusions hospitalized in Soroka University Medical Center in 2010.

Results: All seven patients underwent a comprehensive evaluation followed by pericardiocentesis. Six of the seven cases demonstrated echocardiographic signs of tamponade. Large amounts of hemorrhagic pericardial effusion (> 600 ml) were aspirated from each patient. A pericardial window was performed in two of the seven patients. The causes for the hemorrhagic effusions were malignancy, streptococcal infection, familial Mediterranean fever exacerbation, and idiopathic. Four patients completely recovered. The condition of one patient improved after initiation of chemotherapy for lung cancer, and two patients with progressive malignancies passed away shortly after discharge. Two cases of massive pulmonary embolism were diagnosed which resolved spontaneously without anticoagulation therapy after the effusion was treated.

Conclusions: All cases of pericardial effusion resolved after rapid diagnosis and initiation of specific treatment. Pulmonary embolism in situ may be a complication of large pericardial effusions that does not require anticoagulation treatment after the effusion resolves.
 

Since the Surviving Sepsis Campaign Guideline (SSG) was published in 2004, critical care physicians can readily access the evidence and current recommendations regarding management of patients with severe sepsis and septic shock. However, several issues including a potential conflict of interest in developing the guidelines were disclosed. There have also been dramatic changes in the management of sepsis, supported by high levels of evidence. SSG[1] 2008 was developed to update the evidence using a new grading system. We reviewed select topics, routinely addressed by intensivists in the surgical intensive care unit, that have changed between SSG 2004 and SSG 2008: namely, glucose control, and administration of steroids, recombinant human activated protein C (rhAPC) and total parenteral nutrition.
