A survey evaluated the lifetime and current prevalence of mental disorders in 501 patients seeking assistance with alcohol and other drug problems at an addiction research and treatment facility. Information was gathered using the National Institute of Mental Health Diagnostic Interview Schedule (DIS) and computer diagnoses were generated according to(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)
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)
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)
High-dose intravenous nicardipine has been shown to reduce the incidence of angiographic and symptomatic vasospasm in patients with aneurysmal subarachnoid hemorrhage (SAH), but treatment may be complicated by side effects, including hypotension or pulmonary edema/azotemia. From August, 1989, to January, 1991, 365 patients at 21 neurosurgical centers were(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)
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)
BACKGROUND Prediction of patient outcome is an important aspect of the management and study of aneurysmal subarachnoid hemorrhage (SAH). In the present study, we evaluated the prognostic value of two multivariate approaches to risk classification, Classification and Regression Trees (CART) and multiple logistic regression, and compared them with the best(More)
Management of cerebral gunshot injuries has changed considerably since Cushing's (1916) and Matson's (1948) classification schemes, developed during World War I and World War II, respectively. These military injuries are characterized by either very high mass, low-velocity shrapnel wounds or by high muzzle velocity missiles causing extensive destruction of(More)
Schemes for predicting outcome in craniocerebral missile injury have ranged from Cushing's analysis that was based on the physical characteristics of the injury to complex logistic analyses that incorporate radiographic, laboratory, and clinical data. Generation of predictive scales is discussed, focusing on the utility of the Glasgow Coma Scale (GCS) score(More)
