Previous studies have shown that infusions of propofol, a new intravenous anesthetic, were associated with decreased arterial pressure and slow heart rates. To evaluate the role of baroreflex mechanisms in sustaining these conditions, the effects of two infusion rates of propofol (54 and 108 micrograms.kg-1.min-1) to supplement 66% nitrous oxide in oxygen(More)
The authors report the treatment of a rare type of dural arteriovenous fistula of the paracavernous venous plexus. These fistulas can mimic carotid-cavernous fistulas in both imaging characteristics and clinical presentation, but the anatomical differences require differences in management. The authors describe an integrated open surgical and direct(More)
UNLABELLED OBJECT.: In terms of measuring quality of care and hospital performance, an outcome of increasing interest is the 30-day readmission rate. Recent health care policy making has highlighted the necessity of understanding the factors that influence readmission. To elucidate the rate, reason, and predictors of readmissions at a tertiary/quaternary(More)
Medulloblastomas (MB) are highly aggressive primitive neuroectodermal tumors (PNET) usually located in the posterior fossa. Current treatment for MBs, which includes a combination of surgery, chemotherapy and radiation, remain challenging especially in younger patients. However, advances in the understanding of regulatory pathways in cerebellar development(More)
BACKGROUND Post-transplantation primary central nervous system lymphoma (PT-PCNSL) is a rare neoplasm that can develop within months to years after transplantation, and imaging often reveals multiple lesions with homogeneous or ring enhancement. The clinical and imaging presentation of PT-PCNSL can often be nonspecific and present a diagnostic challenge. (More)
Although patients with cerebral cavernous malformations may remain asymptomatic, they often present with neurological symptoms of headache, hemorrhage and, most commonly, seizure. A review of articles published between 1985 and 2009 was performed to elucidate the prognostic factors which may predict post-operative seizure control. The following(More)
OBJECT Surgical evacuation of spontaneous intracerebral hemorrhage (sICH) remains a subject of controversy. Minimally invasive techniques for hematoma evacuation have shown a trend toward improved outcomes. The aim of the present study is to describe a minimally invasive alternative for the evacuation of sICH and evaluate its feasibility. METHODS The(More)
In 19 patients, minaxolone citrate, a water-soluble steroid anaesthetic agent, has been used as a continuous infusion to supplement nitrous oxide anaesthesia. The minimum infusion rate (MIR) was found to be 11.3 micrograms kg-1 min-1 for patients premedicated with morphine 10 mg i.m. and breathing spontaneously 66% nitrous oxide in oxygen. The(More)
The cardiovascular effects of induction of anesthesia with minaxolone, a new water soluble steroid agent, have been studied in 12 normotensive patients and 5 patients with treated hypertension. The arterial pressure, heart rate and ECG were continuously recorded before and during induction of anesthesia with Minaxolone 0.5 mg kg-1. Cardiac output(More)
