OBJECTIVES This report examines the frequency, type, and prognostic factors of medical (nonneurologic) complications after subarachnoid hemorrhage in a large, prospective study. The influences of contemporary neurosurgical, neurological, and critical care practice on mortality and morbidity rates after aneurysmal subarachnoid hemorrhage are evaluated. (More)
Our goal was to investigate whether the neurokinin-1 receptor (NK1R)-expressing cells of the rostral ventrolateral medulla (RVLM) regulate respiration and arterial pressure (AP). We examined the consequences of their ablation on the cardiorespiratory responses [phrenic nerve discharge (PND) and AP] caused by injecting dl-homocysteic acid (DLH) into the(More)
Female gender is a recognized risk factor for the occurrence of aneurysmal subarachnoid hemorrhage. In the present study the authors analyzed differences in admission characteristics and outcome between 578 women (64%) and 328 men (36%) who were enrolled in a recently completed clinical trial. The female-to-male ratio was nearly 2:1. The women in the study(More)
The blast cell population in AML includes progenitors capable of colony formation in culture. Certain properties of these progenitors have been determined, including their capacity for self-renewal and their sensitivities to the chemotherapeutic drugs cytosine arabinoside (Ara-C) and adriamycin (Adria). Wide patient to patient variation was found in these(More)
OBJECTIVE The management of malignant posttraumatic cerebral edema remains a frustrating endeavor for the neurosurgeon and the intensivist. Mortality and morbidity rates remain high despite refinements in medical and pharmacological means of controlling elevated intracranial pressure; therefore, a comparison of medical management versus decompressive(More)
A multicenter, randomized, blinded, placebo-controlled trial was conducted to study the possible role of intracisternally administered fibrinolytic agent recombinant tissue plasminogen activator (rt-PA) in preventing delayed onset cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH). The target population was patients with ruptured saccular(More)
OBJECTIVE To determine risk factors for vancomycin-resistant Enterococcus (VRE) colonization during a hospital outbreak and to evaluate Centers for Disease Control and Prevention (CDC)-recommended control measures. DESIGN Epidemiological study involving prospective identification of colonization and a case-control study. SETTING A university hospital.(More)
A prospective study on the epidemiology of adverse drug reactions (ADR) in the 200 neonates consecutively admitted to a newborn intensive care unit had shown that 136 ADR occurred in 60 babies (incidence = 30%). 20 of these ADR (14.7%) were major (life-threatening), 34 (25%) were moderate (prolonged hospital stay) and 82 (60.3%) were minor (resolved(More)
BACKGROUND Three randomized controlled trials of the effectiveness of pneumococcal vaccine in elderly and chronically ill adults in the United States have failed to show significant protective efficacy during 44,213 person-years of follow-up. Case-control studies have greater statistical power to detect significant prevention of rare diseases such as(More)
Advanced age is a recognized prognostic indicator of poor outcome after subarachnoid hemorrhage (SAH). The relationship of age to other prognostic factors and outcome was evaluated using data from the multicenter randomized trial of nicardipine in SAH conducted in 21 neurosurgical centers in North America. Among the 906 patients who were studied, five(More)
