BACKGROUND Type I and II endometrial cancer are biologically and clinically distinct, with type II cancers having a high frequency of p53 mutations and an association with chromosomal instability. This raises the hypothesis that one-carbon nutrients (folate, methionine, and the enzymic cofactors vitamins B2, B6, and B12), which mediate chromosomal stability and DNA methylation, may be protectiv...

BACKGROUND AND PURPOSE Multiple sclerosis (MS) patients can present with atypical cavitary lesions mimicking vanishing white matter disease (VWMD). Our objective was to identify brain magnetic resonance imaging (MRI) findings that differentiate these two disorders. METHODS A cross-sectional study was performed including 14 patients with MS with cavitary lesions and 14 patients with VWMD. Two ...

The differential susceptibility of inbred mouse strains DBA/2J (susceptible) and C57BL/6J (resistant) to pulmonary tuberculosis following aerosol infection is under complex genetic control. In this report, transcriptional profiling with RNAs from Mycobacterium tuberculosis-infected lungs was used to investigate the physiological response, cell type, and biochemical pathways underlying different...

BACKGROUND Femoropopliteal percutaneous transluminal angioplasty (PTA) remains limited by restenosis. Although vascular brachytherapy may be effective in reducing restenosis, external beam radiation would be more practical to administer after PTA. METHODS AND RESULTS After femoropopliteal PTA without stent placement, 99 patients were randomly assigned to 0 Gy (placebo; n=24), 7 Gy (n=24), 10....

Background and Purpose—Controversy regarding the risks and benefits of thrombolysis has not been helped by the perception that some trials were “positive” and others “negative” on their primary outcome measure of either “good” or “poor” functional outcome. We wondered whether the definition of good or poor functional outcome might have contributed to this perception, and what effect altering th...

Primary ciliary dyskinesia (PCD) leads to recurrent/chronic respiratory infections, resulting in chronic inflammation and potentially in chronic pulmonary disease with bronchiectasis. We analyzed longitudinal data on body length/height and body mass index (BMI) for 29 children and young adults with PCD aging 1.5-24 years (median, 14.5) who had been diagnosed at the age of 0.5-17 years (median, ...

BACKGROUND AND OBJECTIVES The subclinical pathogenesis of granulomatosis with polyangiitis (GPA) has not been completely elucidated. Proteinase 3 (PR3) antibodies are strongly associated with GPA, but have not been evaluated before disease presentation. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This was a retrospective case-control serum bank study in which PR3 antibodies and C-reactive p...

BACKGROUND In our practice, we noticed an increased frequency of tracheobronchial branching abnormalities (TBAs) in patients with tetralogy of Fallot (ToF). This study aimed to determine whether an association exists between congenital TBAs and ToF with or without pulmonary atresia. METHODS AND RESULTS The frequency of TBAs on chest computed tomography was assessed in 55 patients with ToF wit...
