Background: Pain following brain surgery is a significant problem. Infiltration of the scalp with local intradermal anesthetics was suggested for postoperative pain control but was assessed only in the first hour postoperatively.

Objectives: To evaluate wound infiltration with a single dose of metamizol (dipyrone) for postoperative pain control in patients undergoing awake craniotomy.

Methods: This open, prospective, non-randomized observational study, conducted in anesthesiology and neurosurgical departments of a teaching hospital, included 40 patients undergoing awake craniotomy for the removal of brain tumor. Intraoperative anesthesia included wound infiltration with lidocaine and bupivacaine, conscious sedation using remifentanil and propofol, and a single dose of metamizol (dipyrone) for postoperative pain control. Outcome was assessed by the Numerical Pain Scale on arrival at the postoperative care unit, and 2, 4 and 12 hours after the end of surgery.

Results: On arrival at the postoperative care unit, patients reported NPS[1] scores of 1.2 ± 1.1 in a scale of 0–10 (mean ± SD) (median = 1, range 0–4). The scores were 0.8 ± 0.9, 0.9 ± 0.9, and 1 ± 0.9 at 2 hours, 4 hours, and 12 hours after the end of surgery, respectively. Based on patients' complaints and NPS lower then 3, 27 patients did not require any supplementary analgesia during the first 12 postoperative hours, 11 patients required a single dose of oral metamizol or intramuscular diclofenac, one patient was given 2 mg of intravenous morphine, and one patient required two separate doses of metamizol.

Conclusions: Although the clinical setup prevents the use of placebo local analgesia as a control group, the results suggest the possible role of local intradermal infiltration of the scalp combined with a single dose of metamizol to control postoperative pain in patients undergoing craniotomy.

Background: Infective endocarditis is a common disease with significant morbidity and mortality.

Objectives: To define clinical and echocardiographic parameters predicting morbidity and in-hospital mortality in patients with infective endocarditis hospitalized in a tertiary hospital from 1991 to 2000.

Methods: All patients with definite IE diagnosed according to the Duke criteria were included. We examined relevant clinical features that might influence outcome.

Results: The study group comprised 100 consecutive patients, 77 with native valve and 23 with prosthetic valve endocarditis. The overall in-hospital mortality rate was 8%. There was a higher mortality in the PVE[1] group compared to the NVE[2] group (13% vs. 7%, P = 0.07). The mortality rate in each group, with or without surgery, was not significantly different. Clinical predictors of mortality were older age and hospital-acquired endocarditis. The presence of vegetations and their size were significant predictors of major embolic events and mortality. Staphylococcus aureus was a predictor of mortality (25% vs. 5%, P < 0.005) and abscess formation. Multivariate logistic analysis identified vegetation size and S. aureus as independent predictors of mortality.

Conclusions: Mortality is higher in older hospitalized patients. S. aureus is associated with a poor outcome. Vegetation size is an independent predictor of embolic events and of a higher mortality.

Background: Oral lichen planus is a cell-mediated immune condition of unknown etiology. A possible association of OLP[1] with hepatitis C virus infection has been documented in specific populations. However, no such possible association has been studied in Israel.

Objectives: To assess the prevalence of HCV[2] antibodies among patients with OLP in Israel.

Methods: The prevalence of HCV seropositivity was studied in OLP patients (n=62) and compared with that of a control group (n=65) and with the prevalence among healthy volunteer blood donors (n=225,452) as representatives of the general population.

Results: The prevalence of HCV, as detected by the presence of anti-HCV antibodies screened by enzyme-linked immunosorbent assay, and confirmed by recombinant immunoblot assay, was 4.8%, 1.5% and 0.1%, respectively. HCV seropositivity in the OLP patients was significantly higher than in the healthy blood donors (P < 0.001).

Conclusions: A possible association between OLP and HCV is suggested. Therefore, screening OLP patients for antibodies to HCV is recommended.

Background: Asthma control and treatment compliance are widely investigated issues around the world. Studies have demonstrated relatively low asthma compliance and control in 40–90% of asthma patients in different countries. There are no available data on the Israeli adult asthmatic population

Objectives: To investigate the level of asthma control and compliance in adult asthmatic patients.

Methods: This cross-sectional study of consecutive adult asthmatic patients visiting the pulmonary clinic used a combined questionnaire that included demographics, data on asthma severity and management, and asthma control and compliance scores. Each patient was interviewed and questionnaires were filled out during a routine visit.

Results: The study group comprised 142 males (35.4%) and 259 females (64.6%). Compliance was found optimal in 8 patients (2%), fair in 146 (36%), partial in 156 (39%) and poor in 92 (23%) of the participating asthmatic patients. Asthma control was found optimal in 26 (7%), fair in 124 (31%), partial in 122 (30%) and poor in 129 (32%) patients. Sephardic and Ashkenazi Jewish origin, higher level of education, and treatment protocol including either single fixed-dose inhalers or short-acting beta-agonist bronchodilators significantly improved compliance in our cohort. Socioeconomic status and compliance were found to positively affect asthma control, whereas active smoking negatively affected asthma control in the study patients.

Conclusions: The figures of optimal asthma control and compliance to treatment in Israeli adult asthmatics are low and worse than reported in other studies abroad.
 

Background: Despite improved management of heart failure patients, their prognosis remains poor.

Objectives: To characterize hospitalized HF[1] patients and to identify factors that may affect their short and long-term outcome in a national prospective survey.

Methods: We recorded stages B-D according to the American College of Cardiology/American Heart Association definition of HF patients hospitalized in internal medicine and cardiology departments in all 25 public hospitals in Israel.

Results: During March-April 2003, 4102 consecutive patients were recorded. Their mean age was 73 ± 12 years and 57% were males; 75.3% were hypertensive, 50% diabetic and 59% dyslipidemic; 82% had coronary artery disease, 33% atrial fibrillation, 41% renal failure (creatinine ³ 1.5 mg/dl), and 49% anemia (hemoglobin £ 12 g/dl). Mortality rates were 4.7% in-hospital, 7.6% at 30 days, 18.7% at 6 months and 28.1% at 12 months. Multiple logistic regression analysis revealed that increased 1 year mortality rate was associated with New York Heart Association III–IV (odds ratio 2.07, 95% confidence interval 1.78–2.41), age (for 10 year increment) (OR[2] 1.41, 95% CI[3] 1.31–1.52), renal failure (1.79, 1.53–2.09), anemia (1.50, 1.29–1.75), stroke (1.50, 1.21–1.85), chronic obstructive pulmonary disease (1.25, 1.04–1.50) and atrial fibrillation (1.20, 1.02–1.40).

Conclusions: This nationwide heart failure survey indicates a high risk of long-term mortality and the urgent need for the development of more effective management strategies for patients with heart failure discharged from hospitals.

Background: Heart failure with preserved systolic left ventricular function is a major cause of cardiac disability.

Objectives: To examine the prevalence, characteristics and late clinical outcome of patients hospitalized with HF-PSF[1] on a nationwide basis in Israel.

Methods: The Israel nationwide HF survey examined prospectively 4102 consecutive HF patients admitted to 93 internal medicine and 24 cardiology departments in all 25 public hospitals in the country. Echocardiographic LV function measurements were available in 2845 patients (69%). The present report relates to the 1364 patients who had HF-PSF (LV ejection fraction ≥ 40%).

Results: Mortality of HF-PSF patients was high (in-hospital 3.5%, 6 months 14.2%, 12 months 22.0%), but lower than in patients with reduced systolic function (all P < 0.01). Mortality was higher in patients with HF as the primary hospitalization diagnosis (16.0% vs. 12.5% at 6 months, P = 0.07 and 26.2% vs. 18.0% at 12 months, P = 0.0002). Patients with HF-PSF who died were older (78 ± 10 vs. 71 ± 12 years, P < 0.001), more often female (P = 0.05) and had atrial fibrillation more frequently (44% vs. 33%, P < 0.01). There was also a relationship between mortality and pharmacotherapy: after adjustment for age and co-morbid conditions, mortality was lower in patients treated with angiotensin-converting enzyme inhibitors (P = 0.0003) and angiotensin receptor blockers (P = 0.002) and higher in those receiving digoxin (P = 0.003) and diuretic therapy (P = 0.009).

Conclusions: This nationwide survey highlights the very high late mortality rates in patients hospitalized for HF without a decrease in systolic function. The findings mandate a focus on better evidence-based treatment strategies to improve outcome in HF-PSF patients.

Background: Left ventricular outflow gradient is associated with increased morbidity and mortality in hypertrophic cardiomyopathy. Alcohol septal ablation is the alternative to surgery in cases refractory to drug therapy. The implication of LVOG[1] measured 1 week post-ASA[2] for prediction of outcome is unknown.

Objective: To observe the pattern of LVOG course and prediction of long-term clinical and hemodynamic outcome of ASA.

Methods: Baseline clinical and echocardiographic parameters were prospectively recorded in 14 consecutive patients with a first ASA, at the time of ASA, 3 and 7 days after ASA (in-hospital) and 3 and ≥ 12 months after ASA (last follow-up).

Results: There was improvement in NYHA class, exercise parameters and LVOG in 11 of 14 patients (P < 0.005 in all). Maximal creatine kinase level was lower than 500 U/L in those without such improvement and 850 U/L or higher in successful cases. LVOG dropped from 79 ± 30 to 19 ± 6 mmHg after the ASA. LVOG was 50 ± 21 mmHg on day 3, 39 ± 26 on day 7, 32 ± 26 at 3 months and 24 ± 20 mmHg at last follow-up. LVOG identified 27% sustained procedural successes on day 3 and 73% on day 7. The overall predictive accuracy of the test for sustained success and failure was 36% on day 3 and 71% on day 7. Combination of maximal CK[3] and LVOG on day 7 showed four distinct outcome patterns: "early success" with low LVOG and high CK (73% of successful cases), "late success" with high LVOG and high CK, and "early failure" and "late failure" with both low CK and high or low LVOG, respectively
Conclusion: LVOG measurement 7 days post-ASA combined with maximal CK levels predicts late procedural outcome in the majority of patients

Background: Spontaneous coronary reperfusion occurs in 7–27% of patients with ST elevation myocardial infarction, and is an independent predictor of myocardial salvage, percutaneous coronary intervention success, and improved outcome.

Objectives: To determine the optimal PCI[1] time for patients admitted to the hospital due to STEMI[2] with SCR[3].

Methods: We performed a retrospective analysis of all patients admitted to the coronary care unit between July 2002 and November 2004 with a diagnosis of STEMI with SCR.

Results: The study group comprised 86 patients. There was not a single reinfarction episode during an observation period of 6579 patient hours. Cardiac catheterization was executed early (< 24 hours from pain onset) in 26 patients and late (> 24 hours) in 55. Pre-PCI angiographic TIMI flow 2–3 was seen in > 95% in both groups. PCI was performed more frequently in the “early” group (P = 0.024), while multi-vessel coronary artery disease (P = 0.094) requiring coronary bypass surgery (P = 0.056) was observed more frequently in the “late catheterization” group. Myocardial infarction and angina pectoris at 30 days occurred more frequently in the early catheterization group (P = 0.039), however no difference in any major adverse cardiac events was detected during long-term follow-up (491 ± 245 days).

Conclusions: Reinfarction after STEMI with SCR is a rare event. Early PCI in patients with STEMI and SCR, even when executed with aggressive anti-platelet therapy, seems to result in an excess of early MACE, without any long-term advantage. Prospective randomized trials should determine the optimal PCI timing for these patients.

Background: Echocardiographic ventricular function predicts prognosis and guides management in patients with acute coronary syndromes. In elderly patients, interpretation of echocardiographic measurements may be difficult, especially regarding assessment of diastolic left ventricular function.

Objectives: To examine the usefulness of echocardiographic systolic and echocardiographic diastolic LV[1] function measurements as predictors of long-term outcome in elderly patients with ACS[2].

Methods: We studied 142 consecutive elderly patients (≥ 70 years old, mean age 80 ± 6 years) with ACS who had an echocardiogram at index hospitalization and were in sinus rhythm. LV ejection fraction and diastolic mitral inflow pattern were examined as predictors of survival and repeat hospitalization over a period of 18–24 months.

Results: During the 2 year mean follow-up period 35/142 patients died (25%). Survival was lower in patients with EF[3] < 40% (n=42) as compared to EF ≥ 40% (n=100) (2 year survival rate 61% vs. 81%, P = 0.038). Patients with severe diastolic dysfunction (a restrictive LV filling pattern, n=7) had a lower survival rate than those without (43 vs. 76%, P = 0.009). The most powerful independent predictor of mortality was a restrictive filling pattern (hazard ratio 4.6, 95% confidence interval 1.6–13.5), followed by a clinical diagnosis of heart failure on admission and older age. Rate of survival free of repeat hospitalization was low (33% at 18 months) but repeat hospitalization was not predicted either by EF or by a restrictive filling pattern.

Conclusions: As in the young, echocardiographic measurements of systolic and diastolic LV function predicted long-term survival in elderly patients with ACS. A restrictive filling pattern was the strongest independent predictor of mortality.

Background: The decision to perform primary percutaneous coronary intervention in unconscious patients resuscitated after out-of-hospital cardiac arrest is challenging because of uncertainty regarding the prognosis of recovery of anoxic brain damage and difficulties in interpretation of ST segment deviations. In ST elevation myocardial infarction patients after OHCA[1], primary PCI[2] is generally considered the only option for reperfusion. There are few published studies and no randomized trial has yet been performed in this specific group of patients.

Objectives: To define the demographic, clinical and angiographic characteristics, and the prognosis of STEMI[3] patients undergoing primary PCI after out-of-hospital cardiac arrest.

Methods: We performed a retrospective analysis of medical records and used the prospectively acquired information from the Rambam Primary Angioplasty Registry (PARR) and the Rambam Intensive Cardiac Care (RICCa) databases.

Results: During the period March1998 to June 2006, 25 STEMI patients (21 men and 4 women, mean age 56 ± 11years) after out-of-hospital cardiac arrest were treated with primary PCI. The location of myocardial infarction was anterior in 13 patients (52%) and non-anterior in 12 (48%). Cardiac arrest was witnessed in 23 patients (92%), but bystander resuscitation was performed in only 2 patients (8%). Eighteen patients (72%) were unconscious on admission, and Glasgow Coma Scale > 5 was noted in 2 patients (8%). Cardiogenic shock on admission was diagnosed in 4 patients (16%). PCI procedure was successful in 22 patients (88%). In-hospital, 30 day, 6 month and 1 year survival was 76%, 76%, 76% and 72%, respectively. In-hospital, 30 day, 6 month and 1 year survival without severe neurological disability was 68%, 68%, 68% and 64%, respectively.

Conclusions: In a selected group of STEMI patients after out-of-hospital cardiac arrest, primary PCI can be performed with a high success rate and provides reasonably good results in terms of short and longer term survival.
