BACKGROUND & AIMS Gastrointestinal (GI) diseases account for substantial morbidity, mortality, and cost. Statistical analyses of the most recent data are necessary to guide GI research, education, and clinical practice. We estimate the burden of GI disease in the United States. METHODS We collected information on the epidemiology of GI diseases (including(More)
The advent of radiation therapy as a common modality in the treatment and palliation of breast cancer has led to the observation of morphea developing months to years after supervoltage radiation therapy, in and around the site of treatment. We report 2 new cases of morphea at the site of previous supervoltage radiation therapy for breast cancer. The time(More)
BACKGROUND AND AIMS The elderly represent a growing demographic of patients with IBD. No study has previously described variations in care or medication prescriptions in senior patients with IBD. We compared prescription rates among elderly patients with IBD in four countries using health administrative data. METHODS Databases from the United States (US),(More)
Like many organizations, the health care quality improvement industry is charged with doing more with less. This can only be accomplished by careful scheduling of resources. Geographical differences in adherence to clinical guidelines have been demonstrated. In this paper, geographical analyses are used both to identify regions and providers for healthcare(More)
Vaccination rates among United States (US) adults are suboptimal, resulting in morbidity, mortality, and financial burden attributable to potentially vaccine-preventable diseases (VPDs). Unadjusted annual incidence proportions of VPDs were estimated for Medicaid and commercially insured adults aged 19-64 years using 2006-2010 claims, along with(More)
BACKGROUND AND AIMS Thiopurines, including 6-mercaptopurine (6-MP) and azathioprine (AZA), are the mainstay of maintenance therapy for Crohn's disease (CD). However, studies examining their effectiveness in routine practice among diverse patient populations are lacking. Among a cohort of new users of 6MP/AZA, we described treatment patterns and changes in(More)
Ninety-one patients with chest pain suggestive of acute myocardial infarction were studied by static technetium Tc 99m stannous pyrophosphate scintigraphy and dynamic sodium pertechnetate Tc 99m cardioangiography. Twenty-three of 26 patients (88%) with acute transmural infarcts and 12 of 17 patients (71%) with nontransmural infarcts had abnormal static(More)
The number of publications documenting the utility of electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) for the analysis of biological molecules has increased in geometric proportion spanning diverse areas of research. Currently, we are investigating the capabilities of ESI-FTICR to quantify relative(More)
