BACKGROUND AND PURPOSE Endovascular therapy has increasingly become an acceptable option for treatment of unruptured aneurysms. To better understand the recent trends in the use of and outcomes related to coiling compared with clipping for unruptured aneurysms in the United States, we evaluated the NIS. MATERIALS AND METHODS Hospitalizations for clipping(More)
Antihydrogen spectroscopy promises precise tests of the symmetry of matter and antimatter, and can possibly offer new insights into the baryon asymmetry of the universe. Antihydrogen is, however, difficult to synthesize and is produced only in small quantities. The ALPHA collaboration is therefore pursuing a path towards trapping cold antihydrogen to permit(More)
Cold antihydrogen has been produced at CERN (Amoretti et al., with the aim of performing a high-precision spectroscopic comparison with hydrogen as a test of the CPT symmetry. Hydrogen, a unique system used for the development of quantum mechanics and quantum electrodynamics, has been continuously used to produce high-precision tests of theories and(More)
BACKGROUND Crossed cerebellar diaschisis is a rare finding of hemispheric cerebellar depression following contralateral cerebral injury, hypothesized to result from excessive neuronal excitatory synaptic activity along cortico-pontine-cerebellar pathways. The phenomenon is typically observed following ischemic stroke, but has also been characterized during(More)
Internal carotid artery pseudoaneurysm is an uncommon complication of retropharyngeal and parapharyngeal abscess in children. Treatment of the pseudoaneurysm has evolved in recent years from surgical ligation to endovascular techniques. Neurologic sequelae most commonly consist of Horner's syndrome with cerebral ischemia being uncommon. The clinical course(More)
BACKGROUND Although rare, spinal arteriovenous malformations (AVMs) are thought to be more prevalent in the hereditary Hereditary Hemorrhagic Telangiectasia (HHT) population. METHODS We report a case of a spinal AVM in a 37-year-old female with HHT treated with endovascular embolization. In addition, we report findings from a systematic review of the(More)
BACKGROUND AND PURPOSE The rate and outcomes of neurologic complications of patients receiving extracorporeal membrane oxygenation (ECMO) are poorly understood. The purpose of this study was to identify these parameters in ECMO patients. METHODS All patients receiving ECMO were selected from the Nationwide Inpatient Sample between 2001-2011. The rate and(More)
BACKGROUND Outcomes in pediatric stroke are poorly understood. We sought to determine trends in the use of recombinant tissue plasminogen activator (rt-PA), treatment outcomes, and predictors of mortality for pediatric patients with acute ischemic stroke by using the Nationwide Inpatient Sample. METHODS Using Nationwide Inpatient Sample data from 2001 to(More)
