INTRODUCTION The aim of this study was to determine if laterality of an absent umbilical artery (AUA) is associated with specific sonographic findings, chromosomal defects or postpartum birth defects. MATERIALS AND METHODS In this retrospective cohort study, ultrasound reports and medical records of patients who received an obstetric ultrasound at the(More)
BACKGROUND The incidence, survival, and prevalence of neuroendocrine tumors (NETs) in children were determined as a first step in improving diagnosis and therapy. Outcomes were compared with neuroblastoma, a pediatric malignancy that shares several biomarkers. METHODS Incidence rates, observed survival rates and 31-year limited duration prevalence counts(More)
Warfarin decreases risk of stroke for patients with atrial fibrillation (AF) dependent on percent time in the therapeutic range (TTR) with an international normalized ratio (INR) of 2 to 3. We hypothesized that gender differences in ischemic stroke risk are related to TTR. From the AFFIRM database of 4,060 patients with AF, we determined the incidence of(More)
A recently discovered enzyme system produces antibacterial hypothiocyanite (OSCN(-)) in the airway lumen by oxidizing the secreted precursor thiocyanate (SCN(-)). Airway epithelial cultures have been shown to secrete SCN(-) in a CFTR-dependent manner. Thus, reduced SCN(-) availability in the airway might contribute to the pathogenesis of cystic fibrosis(More)
OBJECTIVE The aim of this study was to identify prognostic factors and markers that influence clinical outcomes in patients with primary fallopian tube carcinoma at a single tertiary health care center. These prognostic factors may be of clinical importance and can subsequently be included in future clinical trials. MATERIALS AND METHODS A retrospective(More)
OBJECTIVE To estimate prevalence of childhood-onset Duchenne and Becker muscular dystrophies (DBMD) in 6 sites in the United States by race/ethnicity and phenotype (Duchenne muscular dystrophy [DMD] or Becker muscular dystrophy [BMD]). METHODS In 2002, the Centers for Disease Control and Prevention established the Muscular Dystrophy Surveillance,(More)
BACKGROUND AND OBJECTIVES The effect of inflammatory bowel disease (IBD) on outcome in patients with colorectal cancer (CRC) remains unclear. Our objective is to evaluate oncologic outcomes of patients with IBD-associated CRC. METHODS We retrospectively reviewed a prospectively maintained database to identify patients with IBD-associated CRC.(More)
OBJECTIVES Few population-based studies have evaluated surgical treatment and outcomes in elderly patients with endometrial cancer. The National Cancer Institute's SEER, Surveillance, Epidemiology and End Results, Program provides a database to examine this issue. The objective of this study was to determine the extent to which elderly women with(More)
OBJECTIVES To establish the associations between threshold estimates of 4 perimetric tests and to define and compare the tests' effective dynamic ranges. METHODS We examined 152 patients with glaucoma and 80 controls using standard automated perimetry (SAP) with stimulus size III, SAP with size V, and motion and matrix perimetry. We explored the intertest(More)
Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements(More)
