OBJECTIVES Antiperinuclear factor (APF), antikeratin antibodies (AKA), and anti-RA 33 antibodies are currently considered to be good markers for the diagnosis of adult rheumatoid arthritis with or without rheumatoid factor (RF). The prevalence of these markers was retrospectively reviewed in children with juvenile chronic arthritis (JCA) to determine whether they were associated with specific f...

OBJECTIVES Antikeratin antibodies (AKA) and antiperinuclear factor (APF) are specific antibodies found very early in rheumatoid arthritis (RA). The objective of this eight year follow up study was to assess the value of early AKA and APF assays in predicting functional disability and cartilage damage. METHOD In 2000, 64 patients tested for AKA and APF (antifilaggrin antibodies) between 1990 a...

Prosthetic joint infection (PJI) is a serious complication of total knee arthroplasty (TKA). Control of infection after a failed two-stage TKA is not always possible, and the resolution of infection may require an above-knee amputation (AKA) or a the-knee (KF). The purpose of this review is to determine which treatment method (AKA or KF) yields better function and ambulatory status for patients...

In SeaWinds data processing, normalized microwave radar backscatter (aka sigma0) can be grouped differently depending on whether and how to weight the “slices” using the X-factor [1]. The “SeaWinds on QuikSCAT” processor uses either so-called “egg” method or “composite” (or in short “comp1”) method. The NOAA processor uses so-called “composite of composite” or “composite squared” (or in short “...

BACKGROUND AND PURPOSE Imaging of the anterior superficial spinal cord arteries by MR angiography is hindered by their small calibers and the similarity in configuration with the anterior superficial spinal cord veins. To validate the location and spatial configuration of the great anterior radiculomedullary artery, (ie, the Adamkiewicz artery [AKA]), contrast-enhanced MR angiography (CE-MRA) w...

OBJECTIVE To investigate the prevalence of anti-cyclic citrullinated peptide (anti-CCP) and anti-keratin antibodies (AKA) in patients with primary Sjögren's syndrome. METHODS 149 patients with a diagnosis of primary Sjögren's syndrome according to the European/American consensus criteria were recruited from three French medical centres. The presence of anti-CCP was determined by enzyme linked...

Supply With great interest, we read the article by Uotani and colleagues in the February issue of the American Journal of Neuroradiology. The authors compared intravenous and intra-arterial contrast agent application for the localization of the Adamkiewicz artery (AKA) in different patients scheduled for thoracic or thoracoabdominal aortic aneurysm repair with use of CT angiography (CTA). Intra...
