OBJECTIVE This prospective, randomized, controlled study was designed to investigate the safety, feasibility, and preliminary efficacy of long-term CSF drainage via a low-flow ventriculoperitoneal shunt in subjects suffering from AD. METHODS Twenty-nine subjects selected for probable AD (National Institute of Neurological and Communicative Diseases and(More)
OBJECTIVE To evaluate the production rate of CSF in patients with differing disease states. METHODS The authors measured the production rate of CSF in three groups of patients: five patients with PD below age 60 (aged 51 +/- 4 years, mean +/- SD), nine with PD over age 60 (aged 69 +/- 6 years, mean +/- SD), and seven with dementia of the Alzheimer's type(More)
Patients commonly present with orthopedic injuries to the emergency department (ED). Although radiographs are the standard of care for evaulating these injuries, point-of-care ultrasound is being increasingly used to make the diagnosis. This modality can be useful in patients who are too clinically unstable to leave the acute care ED and in nonverbal(More)
BACKGROUND Alzheimer disease (AD) has been associated with abnormal cerebral clearance of macromolecules, such as amyloid and microtubule-associated-protein tau (MAP-tau). We hypothesized that improving clearance of macromolecules from the CNS might slow the progression of dementia. OBJECTIVE This prospective, randomized, double-blinded,(More)
BACKGROUND Bedside ultrasound is emerging as a useful tool in the assessment of intravascular volume status by examining measurements of the inferior vena cava (IVC). Many previous studies do not fully describe their scanning protocol. OBJECTIVES The objective of this study was to evaluate which of three commonly reported IVC scanning methods demonstrates(More)
AIM The purpose of this study was to compare lung ultrasound findings in both the supine and upright positions in heart failure patients presenting with dyspnea or chest pain. METHODS AND RESULTS We performed lung ultrasonography on 50 heart failure patients in the emergency department. Each subject underwent eight-zone lung sonography in the seated(More)
We present 2 recent cases of heterotopic pregnancy in which bedside sonography performed by the treating emergency physician was used to identify the heterotopic pregnancy and facilitate prompt gynecologic intervention. The cases, the sonographic approach to the diagnosis of heterotopic pregnancy, and a review of the literature are presented.
We report a case where an emergency physician using bedside ocular ultrasound was able to diagnose vitreous hemorrhage and lens dislocation in an elderly patient. Bedside ultrasound performed by a physician trained in this imaging modality can diagnose ocular emergencies, facilitating appropriate consultation and treatment.
Emergency physicians, obstetrician-gynecologists, and other medical specialists use pelvic sonography when caring for patients presenting with early pregnancy-related symptoms. A thin endomyometrial mantle and eccentric placement of a gestational sac should raise the suspicion for an abnormally implanted pregnancy. In such cases, an interstitial ectopic(More)
