OBJECTIVES/HYPOTHESIS To improve the test standards for a version of the Romberg test and to determine whether measuring kinematic variables improved its utility for screening. STUDY DESIGN Healthy controls and patients with benign paroxysmal positional vertigo, postoperative acoustic neuroma resection, and chronic peripheral unilateral weakness were(More)
Locomotion is impaired in some people with vestibular disorders. Performance on cognitive tasks is also impaired in many people with vestibular disorders. The goal of this study was to determine if patients with vestibular disorders have decreased ability to complete a dual task performance involving a cognitive task, an additional motor task or both tasks,(More)
BACKGROUND Sleep duration is dependent on circadian rhythm that controls a variety of key cellular functions. Circadian disruption has been implicated in colorectal tumorigenesis in experimental studies. We prospectively examined the association between sleep duration and risk of colorectal cancer (CRC). METHODS In the Women's Health Initiative(More)
The goal of this study was to determine if parameters of gait are related to the path integration deficits in some people with vestibular disorders. We tested normals, and two groups of vestibularly impaired people, with unilateral benign paroxysmal positional vertigo and with unilateral weakness. Each group had 20 subjects. They walked straight ahead for(More)
BACKGROUND Dynamic visual acuity (DVA) testing may be a useful, indirect indicator of vestibulo-ocular reflex function. Previous evidence shows that acuity for 2 m targets differs little between patients and normals using a 75 ms display duration and that healthy subjects do not differ in acuity when standing and walking while viewing a far target but they(More)
Dynamic visual acuity (DVA) may be a useful indicator of the function of the vestibulo-ocular reflex (VOR) but most DVA tests involve active head motion in the yaw plane. During gait the passive, vertical VOR may be more relevant and passive testing would be less likely to elicit compensatory strategies. The goal of this study was to determine if testing(More)
BACKGROUND AND OBJECTIVES To assess self-perceived proficiency in minimally invasive surgical procedures among fourth-year Ob/Gyn residents in the United States and to evaluate trends in self-perceived proficiencies by comparing the current survey to a similar survey distributed in 2001. METHODS A Web-based survey was sent out to all fourth-year residents(More)
BACKGROUND AND OBJECTIVES Mechanical bowel preparation (MBP) has been used prior to total laparoscopic hysterectomy (TLH), but evidence for its use is lacking. Our study seeks to assess whether or not completion of preoperative MBP prior to TLH improves visualization of the surgical field, bowel handling, or overall ease of the operation. METHODS Women(More)
OBJECTIVES/HYPOTHESIS To determine how eye closure, test positions, and stimulus frequencies influence ocular vestibular evoked myogenic potentials. STUDY DESIGN This study used a within-subjects repeated measures design. METHODS Twenty asymptomatic subjects were each tested on ocular vestibular evoked myogenic potentials in three head/eye conditions at(More)
S creening for gestational diabetes mellitus requires an oral glucose challenge test with a 50-g glucola beverage and venous blood sample after 1 h. A " positive screen " is defined as a ve-nous blood glucose of either .130 mg/dL or 140 mg/dL (1,2), and the patient then undergoes a diagnostic fasting 3-h glucose tolerance test (GTT) with a 100-g glucola(More)
