Gangliogliomas are rare tumors, primarily seen in patients under the age of 30 years. They occur least commonly in the spinal cord. This report presents a 2 1/2-year-old boy who harbored an intramedullary conus tumor with the light microscopic appearance of a ganglioglioma. The neurobiological behavior of this tumor is yet to be determined.
BACKGROUND Patients undergoing vascular surgical procedures are at high risk for perioperative myocardial infarction (PMI). This study was undertaken to identify predictors of PMI and in-hospital death in major vascular surgical patients. METHODS From the Vascular Surgery Registry (6,948 operations from January 1989 through June 1997) the authors(More)
Acute mesenteric ischemia (AMI) is a curable disease if diagnosis and therapy are instituted before irreversible changes have occurred. AMI has been diagnosed with increasing frequency, during the last two decades, yet the mortality rate remains as high as 80% to 95%. Ninety-two patients with AMI were treated at Hadassah University Hospital between 1952 and(More)
Since 1978, 21 patients (12 men and nine women) suffering from mesenteric venous thrombosis (MVT) were treated at the Hadassah University Medical Center. The cause of MVT was multifactorial, and in only six patients was the process defined as primary or idiopathic. A preoperative diagnosis of MVT was made in eight patients. Surgical management of the(More)
OBJECTIVE Patients with coronary artery disease (CAD) who undergo noncardiac surgery are at increased risk for perioperative myocardial infarction (PMI). Undergoing successful coronary artery bypass grafting (CABG) before such surgery has been shown to decrease perioperative cardiac morbidity and mortality. Percutaneous transluminal coronary angioplasty(More)
PURPOSE Atherosclerotic carotid artery stenosis (CAS) is the most common cause of stroke in young adults. We retrospectively studied clinical characteristics of premature CAS and the safety and durability of carotid endarterectomy (CEA) in 56 patients 50 years of age or younger (mean, 46.4 years; 34 (60%) males; group I) who underwent primary CEA at the(More)
Abnormal hemodynamics play a central role in the development and perpetuation of high blood pressure. We hypothesized that hypertension therapy guided by noninvasive hemodynamics with impedance cardiography could aid primary care physicians in reducing blood pressure more effectively. Uncontrolled hypertensive patients on 1 to 3 medications were randomized(More)
Arterial occlusive disease (AOD) which is rarely described in patients with inflammatory bowel disease, is mainly associated with Crohn's disease (CD), and its etiology and natural course are unknown. We studied six patients (five women, one man) with CD and major lower extremity AOD who were treated at the Cleveland Clinic between 1985 and 1994. These were(More)
A study was conducted on the effects of mild hemorrhage-induced hypovolemia and subsequent fluid replacement with lactated Ringer's or dextran solution on the hearts of 61 pentobarbital anethetized open-chest New Zealand white rabbits. After a blood loss equivalent to 1.25% of body weight, blood flow in the subepicardial and subendocardial regions of the(More)
Bowel necrosis is a serious condition with a very high mortality rate. The earlier the diagnosis is made, the better chance for survival. Ultrasound is a primary imaging technique in the diagnosis of the acute abdomen. Three cases are presented in which bowel wall gas could be demonstrated on ultrasound. In all cases there was computed tomographic and(More)
