Introduction: The clinical benefit of thrombolytic treatment over heparin in patients with pulmonary embolism without hemodynamic compromise remains controversial. In these patients bolus tenecteplase has the potential to provide an effective and safe thrombolysis. Methods: We evaluated the effect of tenecteplase on right ventricle dysfunction (RVD) assessed by echocardiography in hemodynamically stable patients with PE in a multicenter, randomized, double-blind, placebo-controlled study. RVD was defined as right/left ventricle end-diastolic dimension ratio > 1 in the apical 4-chamber view. Patients were randomized to receive weight-adjusted single-bolus tenecteplase or placebo. All patients received unfractionated heparin. Reduction of RVD at 24 hours was the primary efficacy end-point and was evaluated by an independent committee unaware of treatment allocation. Results: Overall, 58 patients were randomized. Echocardiograms were adequate for efficacy analysis in 51 patients, 23 randomized to tenecteplase and 28 to placebo. The reduction of right to left ventricle end-diastolic dimension ratio at 24 hours was 0.31 ± 0.08 in patients randomized to tenecteplase as compared to 0.10 ± 0.07 in patients randomized to placebo (p = 0.04). One patient randomized to tenecteplase suffered a clinical event (recurrent pulmonary embolism) in comparison to three patients randomized to placebo (1 recurrent pulmonary embolism; 1 clinical deterioration and 1 non pulmonary embolism-related death). Two non fatal major bleedings occurred with tenecteplase (1 intracranial) and one with placebo. Conclusion: In hemodynamically stable patients with PE, treatment with single bolus tenecteplase is feasible at the same dosages used for acute myocardial infarction and is associated with reduction of RVD at 24 hours. Whether this benefit is associated with an improved clinical outcome without excessive bleeding is currently explored in a large clinical trial. © 2009 Elsevier Ltd. All rights reserved.

The PRELUDE (PRogrammed ELectrical stimUlation preDictive valuE) prospective registry was designed to assess the predictive accuracy of sustained ventricular tachycardia/ventricular fibrillation (VTs/VF) inducibility and to identify additional predictors of arrhythmic events in Brugada syndrome patients without history of VT/VF. Brugada syndrome is a genetic disease associated with increased risk of sudden cardiac death. Even though its value has been questioned, inducibility of VTs/VF is widely used to select candidates to receive a prophylactic implantable defibrillator, and its accuracy has never been addressed in prospective studies with homogeneous enrolling criteria. Patients with a spontaneous or drug-induced type I electrocardiogram (ECG) and without history of cardiac arrest were enrolled. The registry included 308 consecutive individuals (247 men, 80%; median age 44 years, range 18 to 72 years). Programmed electrical stimulation was performed at enrollment, and patients were followed-up every 6 months. During a median follow-up of 34 months, 14 arrhythmic events (4.5%) occurred (13 appropriate shocks of the implantable defibrillator, and 1 cardiac arrest). Programmed electrical stimulation performed with a uniform and pre-specified protocol induced ventricular tachyarrhythmias in 40% of patients: arrhythmia inducibility was not a predictor of events at follow-up (9 of 14 events occurred in noninducible patients). History of syncope and spontaneous type I ECG (hazard ratio [HR]: 4.20), ventricular refractory period <200 ms (HR: 3.91), and QRS fragmentation (HR: 4.94) were significant predictors of arrhythmias. Our data show that VT/VF inducibility is unable to identify high-risk patients, whereas the presence of a spontaneous type I ECG, history of syncope, ventricular effective refractory period <200 ms, and QRS fragmentation seem useful to identify candidates for prophylactic implantable cardioverter defibrillator. © 2012 American College of Cardiology Foundation.

Objective: This study aimed to evaluate the surgical treatment of acute pancreatitis in Italy and to assess compliance with international guidelines. Methods: A series of 1173 patients in 56 hospitals were prospectively enrolled and their data analysed. Results: Twenty-nine patients with severe pancreatitis underwent surgical intervention. Necrosectomy was performed in 26 patients, associated with postoperative lavage in 70% of cases. A feeding jejunostomy was added in 37% of cases. Mortality was 21%. Of the patients with mild pancreatitis, 714 patients with a biliary aetiology were evaluated. Prophylactic treatment of relapses was carried out in 212 patients (36%) by cholecystectomy and in 161 using a laparoscopic approach. Preoperative endoscopic retrograde cholangiopancreatography was associated with cholecystectomy in 83 patients (39%). Forty-seven patients (22%) were treated at a second admission, with a median delay of 31 days from the onset of pancreatitis. Eighteen patients with severe pancreatitis underwent cholecystectomy 37.9 days after the first admission. There were no deaths. Discussion: The results indicate poor compliance with published guidelines. In severe pancreatitis, early surgical intervention is frequently performed and enteral feeding is seldom used. Only a small number of patients with mild biliary pancreatitis undergo definitive treatment (i.e. cholecystectomy) within 4 weeks of the onset of pancreatitis. © 2010 International Hepato-Pancreato-Biliary Association.

Aims and background. Pseudomyxoma peritonei (PMP) is a rare clinical entity characterized by diffuse intraabdominal gelatinous collections with mucinous implants on the peritoneal surfaces and omentum. This condition should be considered a borderline malignancy with disease progression over time. Encouraging treatment results have been recently reported with the combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Methods. From December 2003 to December 2010, 18 patients with PMP were referred to our institution. All patients underwent peritonectomy and CRS combined with HIPEC in accordance with Sugarbaker's procedure. Results. The mean Peritoneal Cancer Index score was 27.6 (range, 5-39). Twelve (67%) patients had disseminated peritoneal adenomucinosis and 6 (33%) peritoneal mucinous carcinomatosis. Optimal cytoreduction with no visible residual disease or residual disease ≤2.5 mm in diameter was achieved in all patients. The mean duration of the surgical procedure including HIPEC was 9 hours and 30 minutes (range, 5-13 hours); major morbidity occurred in 30% of patients and the mortality was 11%. The mean follow-up was 27 months (range, 1-72) and the 5-year overall survival 66%. Conclusions. In line with the existing literature, our experience suggests that patients with PMP could benefit from CRS + HIPEC in terms of survival and locoregional disease control. © Il Pensiero Scientifico Editore.
