OBJECTIVE The safety and efficacy of Minimicrospheres, which are enteric-coated, delayed-release pancrelipase capsules, on fat absorption in pediatric/adolescent and adult cystic fibrosis (CF) patients was assessed. Exocrine pancreatic insufficiency, common in CF patients, causes steatorrhea due to insufficient release of pancreatic enzymes. METHODS In(More)
The quantitative analysis of the mobile high-energy phosphorus metabolites in isovolumic Langendorff-perfused rabbit hearts has been performed by 31P NMR utilizing rapid pulse repetition to optimize sensitivity. Absolute quantification required reference to an external standard, determination of differential magnetization saturation and resonance peak area(More)
BACKGROUND Coronary perforations represent a serious complication of percutaneous coronary intervention (PCI). METHODS We performed a retrospective analysis of documented coronary perforations at Massachusetts General Hospital from 2000 to 2008. Medical records review and detailed angiographic analysis were performed in all patients. RESULTS Sixty-eight(More)
This study was undertaken to determine whether positron emission tomography (PET) performed after the intravenous injection of 11C-palmitate permits differentiation of patients with ischemic from those with nonischemic dilated cardiomyopathy. PET was performed after intravenous injection of 11C-palmitate in 10 patients with ischemic and in 10 with(More)
Complications of acute myocardial infarction can be categorized as nonarrhythmic or arrhythmic; the latter is discussed elsewhere. Patients are at risk for a number of potentially serious or fatal complications during or after the acute infarction phase. These include shock, left ventricular free wall rupture, rupture of the interventricular septum,(More)
Looking at prominent centers of software activity across the globe we observe that software developers tell narratives about themselves to explain their identity and their successes. For example, the USA thinks in terms of the cowboy programmer, Ireland the Celtic Tiger, and Israel the commando programmer. These narratives provide insights into the mental(More)
To determine the ability to detect thrombus by angiography, angioscopy was performed before angiography in patients undergoing interventional procedures and the data collected in a blinded fashion. These data demonstrated that the sensitivity of angiography to detect white thrombus was 50% and the specificity was 95%, whereas the sensitivity and specificity(More)
We studied the usefulness of tetanus toxoid (TT) as a skin test antigen in assessing cellular immune function. Hospitalized patients were skin tested with four antigens, and the response rates between these antigens were compared. Candida and mumps antigens resulted in significantly more positive responses than did TT or PPD. The response rate to the TT(More)
