The computed tomographic (CT) findings in 52 patients with histologically proved esophageal carcinoma were reviewed. In 30 of these patients, the CT findings were correlated with findings at surgery or autopsy. CT was found to be highly accurate in predicting tumor size and assessing invasion of the tracheobronchial tree and spread to the liver, adrenals,(More)
OBJECTIVE The purpose of our study was to determine the prevalence, distribution, and clinical significance of pancreatic ductal changes due to pancreatitis on ERCP in patients with pancreas divisum. MATERIALS AND METHODS From January 1993 through December 1997, 1714 patients underwent 2469 ERCP studies. Ninety-four patients (5.5%) had pancreas divisum.(More)
BACKGROUND/AIMS Although dysphagia in patients with peptic stricture is attributed to a decreased luminal diameter, coexistent esophagitis may be an equally important cause. The goals of this study were to determine whether medical healing of esophagitis in patients with stricture improves dysphagia and decreases dilatation need and to compare the efficacy(More)
OBJECTIVE Our purpose was to define a simple technique for timing a barium swallow by which radiologists can assess esophageal emptying in patients with achalasia before and after minimally invasive therapy. Our purpose was also to determine the best method of quantifying the degree of emptying using this timed technique. MATERIALS AND METHODS In the(More)
Relapse is common in substance use disorders (SUDs), even among treated individuals. The goal of this article was to systematically review the existing evidence on mindfulness meditation-based interventions (MM) for SUDs. The comprehensive search for and review of literature found over 2000 abstracts and resulted in 25 eligible manuscripts (22 published, 3(More)
According to a recommendation from WHO (World Health Organisation) for prevention of a possible rabies infection, active vaccination has to be combined with application of immunoglobulin to get a fast protective effect. At present, preparations of purified human or equine rabies-specific immunoglobulin are used. We have generated a human rabies-specific(More)
BACKGROUND Intrasphincteric injection of botulinum toxin is a new treatment option for achalasia. AIMS To compare the immediate and long term efficacy of botulinum toxin with that of pneumatic dilatation. METHODS Symptomatic patients with achalasia were randomised to botulinum toxin (22 patients, median age 57 years) or pneumatic dilatation (20(More)
BACKGROUND & AIMS No multicenter study has been reported evaluating the performance and interobserver variability of computerized tomographic colonography. The aim of this study was to assess the accuracy of computerized tomographic colonography for detecting clinically important colorectal neoplasia (polyps >or=10 mm in diameter) in a multi-institutional(More)
The relative efficacy of double- and single-contrast radiographs of the esophagus in the detection of esophagitis was compared with findings at esophagoscopy in 52 patients. The addition of double-contrast views to the examination increased the number of radiographic abnormalities seen and led to the radiographic detection of esophagitis in four patients in(More)
A total of 103 consecutive patients with suspected biliary obstruction were studied using both computed tomography (CT) and ultrasound (US) to evaluate the relative accuracy of the methods. In 47 patients with confirmed obstruction, CT and US were comparable accurate in differentiating obstruction from nonobstruction. The precise level of obstruction was(More)
