BACKGROUND To describe geographic variation in population-based rates of carotid artery stenting (CAS) and carotid endarterectomy (CEA) performed in Medicare beneficiaries. METHODS AND RESULTS Medicare claims and enrollment data were used to calculate age, sex, and race-adjusted rates of CAS and CEA for Medicare beneficiaries in each of 306 hospital referral regions between 1998 and 2007. Pro...
A method to prepare monodisperse and simultaneously NMR-visible and fluorescent colloidal particles is described, and a systematic approach to obtain spectrally resolved diffusion coefficient for every component in a monodisperse colloidal suspension is presented. We also prepared bidisperse colloidal suspensions, where each colloid component has a distinct NMR spectral signature, and obtained ...
Central anticholinergic syndrome (CAS) following general anesthesia (GA) is a well known syndrome in children and adults. Many cases of CAS have been previously reported in the literature. However, there are only two reports of post resuscitation CAS after administration of small doses of atropine. Hereby, we report a case of CAS in a child undergoing complete dental restoration under GA after ...
Les auteurs presentent quatre cas familiaux de l'ictcre chronique, non hemolytique, benin, avec une hyperbilirubinemie a predominance conjuguee. Deux malades ont ete soumis a des investigations plus poussees. Les. voies biliaires etaient visib1es a la cholecystographie ora1e et le taux plasmatique de la BSP, elevc au depart, presentait une pente d'elimination progressive sans remontee secondai...
Colloidal Gas Aphron as a mobility control in enhanced oil recovery is becoming attractive; it is also designed to block porous media with micro-bubbles. In this paper, the effects of surfactant concentration, polymer concentration, temperature and salinity on the bubble size of the Colloidal Gas Aphron were studied. Effects of injection rates, Colloidal Gas Aphron fluid composition, heterogene...
BACKGROUND Celiac artery stenosis (CAS) may be caused by atherosclerotic degeneration or compression exerted by the arched ligament of the diaphragm. Mitral valve prolapse (MVP) is the most common valvular disorder. There are no reports on an association between CAS and MVP. METHODS 1560 (41%) out of 3780 consecutive patients undergoing echocardiographic assessment of MVP, had Doppler sonogra...
BACKGROUND AND OBJECTIVES Cigarette smoking is a risk significant factor in coronary artery disease (CAD) and vasospastic angina (VSA). However, it is largely unknown whether smoking adds to any long-term clinical risk in VSA patients. SUBJECTS AND METHODS A total of 2797 patients without significant CAD underwent acetylcholine (Ach) provocation test between November 2004 and October 2010. Pa...
Fertilization exceeding crop requirements causes an accumulation of phosphorus (P) in soils, which might increase concentrations of dissolved and colloidal P in drainage. We sampled soils classified as Typic Haplorthods from four fertilization experiments to test (i) whether increasing degrees of phosphorus saturation (DPS) increase concentrations of dissolved and colloidal P, and (ii) if criti...
This study represents a prospective audit comparing carotid artery stenting (CAS) with carotid endarterectomy (CEA), performed by a single surgical team. Between January 2005 and December 2008, 440 patients were referred; 177 had CAS and 263 CEA. Selection of procedure was individualised and contra-indications for CAS included internal carotid artery (ICA) stenosis > 85-90%, intraluminal thromb...
BACKGROUND Coronary artery disease (CAD) may coexist with extracranial carotid artery stenosis (ECAS), but the influence of CAD on procedure-related complications after carotid artery stenting (CAS) has not been well investigated. The study aimed to determine the impact of CAD on the occurrence of peri-CAS cerebral ischemic lesions on diffusion-weighted imaging (DWI) scanning. METHODS Coronar...
