The diagnosis and management of peripheral vascular disease has undergone tremendous change during the past two decades. Diagnostic angiography is complemented and, in some cases, even supplanted by digital subtraction techniques, duplex sonography, intravascular ultrasound, and magnetic resonance imaging. Similarly, percutaneous transluminal angioplasty has evolved from a novelty to a vital co...

Background Of the three opioid receptors, μ (MOP), δ (DOP) and (KOP), the MOP type is the most involved in the action of opioids in the gut. Experimental studies on models of intestinal inflammation and inflammatory bowel disease (IBD) support an anti-inflammatory role of peripheral MOP receptors in the gut, besides their involvement in pain control (analgesia) and gastrointestinal motility (an...

Contour integration was measured in the normal peripheral field to determine if an explanation based solely on the known peripheral positional uncertainty was sufficient to explain performance. The task involved the detection of paths composed of micropatterns with correlated carrier orientations embedded in a field of similar micropatterns of random position and orientation (Field, D. J., Haye...

Distractor interference effects were compared between distractors in the periphery and those placed at fixation. In 6 experiments, the authors show that fixation distractors produce larger interference effects than peripheral distractors. However, the fixation distractor effects are modulated by perceptual load to the same extent as are peripheral distractor effects (Experiments 1 and 2). Exper...

BACKGROUND Femoral vein (FV) catheterization is required for critically ill patients, patients with difficult peripheral intravenous access, and patients undergoing major surgery. The purpose of this study was to evaluate the effects of hip abduction with external rotation (frog-leg position), and the frog-leg position during the reverse Trendelenburg position on diameter, cross-sectional area ...

THE Society of Interventional Radiology (SIR) has been the primary developer and leader in diagnostic arteriography and interventional procedures, including peripheral angioplasty and vascular stent placement, since the Society was founded in 1973. SIR has been involved in the education and training of physicians in these procedures and has developed standards for the safe and successful perfor...

BACKGROUND Nocturnal exacerbation of neuropathic symptoms (NENS) is a recognized symptom of diabetic peripheral neuropathy (DPN). Symptoms are often worse in bed, may not be controlled with medication and disrupt sleep patterns. NENS can also be present in patients with spinal stenosis (SS), with or without concomitant peripheral neuropathy and may be related to sleep position. Extension positi...
