OBJECTIVES We sought to establish what historical findings are predictive of the cause of syncope. BACKGROUND The clinical features of the various types of syncope have not been systematically investigated. METHODS Three hundred forty-one patients with syncope were prospectively evaluated. Each patient was interviewed using a standard questionnaire. A(More)
OBJECTIVES Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP/ES) can be associated with unforeseeable complications, especially when involving postprocedural pancreatitis. The aim of the study was to investigate risk factors for complications of ERCP/ES in a prospective multicentric study. METHODS One hundred fifty variables(More)
BACKGROUND Intrasphincteric injection of botulinum toxin (Botx) has been proposed as treatment for oesophageal achalasia. However, the predictors of response and optimal dose remain unclear. AIMS To compare the effect of different doses of Botx and to identify predictors of response. PATIENTS/METHODS A total of 118 achalasic patients were randomised to(More)
This study was undertaken to assess the value of sublingual nitroglycerin administration during upright tilt as a simple practical test for the diagnosis of vasovagal syncope. To this purpose, 235 patients with syncope of unknown origin and no evidence of organic heart disease (110 men, mean age 52 +/- 20 years) and 35 asymptomatic control subjects(More)
AIMS The clinical features of the various types of neurally mediated reflex syncope have not been systematically investigated and compared. We sought to assess and compare the clinical spectrum of neurally mediated reflex syncopes. METHODS AND RESULTS Four hundred sixty-one patients with syncope were prospectively evaluated and 280 had neurally mediated(More)
The aim of our present study was to assess the value of nitroglycerin infusion during upright posture as a new provocative test for diagnosis of vasovagal syncope. To this purpose 40 patients with unexplained syncope (17 men and 23 women, mean age 47 years) and 25 asymptomatic control subjects with negative baseline head-up tilt underwent two other tilting(More)
AIMS This study compared the efficacy and safety of intravenous dofetilide with amiodarone and placebo in converting atrial fibrillation or flutter to sinus rhythm. METHODS AND RESULTS One hundred and fifty patients with atrial fibrillation or flutter (duration range 2 h-6 months) were given 15-min intravenous infusions of 8 microg. kg(-1)of dofetilide(More)
OBJECTIVE Traditional quantitative analysis of 24-h esophageal pH monitoring data does not include the pH of reflux episodes. Area under pH 4 (AU4) is a recently introduced parameter that describes the acid exposure rate through both duration and depth of pH falls. METHODS In Study A, we enrolled 20 healthy controls and 42 patients (18 without(More)
BACKGROUND The appropriate diagnostic work-up of patients with syncope is not well defined. We applied the guidelines of Italian 'Associazione Nazionale Medici Cardiologi Ospedalieri' to a group of consecutive patients with syncope referred to three Syncope Units. The aim of the study was to evaluate the applicability of those guidelines in the 'real world'(More)
Recurrent neurally mediated syncope represents a common clinical event and a therapeutic challenge. Recently tilt training has been proposed for the treatment of recurrent neurally mediated syncope. To evaluate the efficacy of tilt training in preventing tilt-induced syncope and its feasibility, this controlled, randomized study was undertaken. Sixty-eight(More)
