The following paper discusses the topic of edge detection in X-ray hand images. It criticises existing solution by highlighting a design fault, which is a carelessly chosen function and then proposes a way to eliminate the fault by replacing it with better suited function. The search for this function and its results are also discussed in this paper. It also presents the aspect of preand postpr...

INTRODUCTION The aim of this study was to investigate whether serum biomarker levels of C2C, C1,2C, CS846, and CPII can predict the long-term course of disease activity and radiographic progression early in the disease course of rheumatoid arthritis (RA). METHODS In patients in the CAMERA trial, levels of biomarkers were evaluated at baseline and after 1 year of treatment. Relations of (chang...

BACKGROUND AND OBJECTIVE The most common risk factor for bisphosphonate-related osteonecrosis of the jaws (BRONJ) is dentoalveolar surgery. It has been suggested that reduced serum C-terminal telopeptide (CTX) can determine the degree of osteoclast suppression and may predict the development of BRONJ after dentoalveolar surgery. Although there are many radiographic appearances associated with B...

BACKGROUND Metal prostheses are useful for restoring elbow and forearm stability when the radial head cannot be fixed after a fracture. Because the anatomy of the radial head is difficult to reproduce with a prosthesis, two different options have been proposed: a bipolar prosthesis with a fixed stem and a mobile head, and a monoblock prosthesis with a smooth stem that is intentionally fixed loo...

A patient with a corrected coarctation of the aorta subsequently developed infective endocarditis on a congenital bicuspid aortic valve. Resolution of the radiographic bone changes of hypertrophic pulmonary osteoarthropathy was demonstrated following treatment of the infection.

Longitudinal change in five cognitive abilities was investigated to determine if the direction or magnitude of change was related to the individual's ability level. Adults between 18 and 97 years of age performed three versions of 16 cognitive tests on two occasions separated by an average of 2.7 years. In order to control for influences associated with regression toward the mean, level of abil...

Assessing cognitive change in older adults is a common use of neuropsychological services, and neuropsychologists have utilized several strategies to determine if a change is "real," "reliable," and "meaningful." Although standardized regression-based (SRB) prediction formulas may be useful in determining change, SRBs have not been widely applied to older adults. The current study sought to dev...

It is widely recognized that experience with cognitive tests can influence estimates of cognitive change. Prior research has estimated experience effects at the level of groups by comparing the performance of a group of participants tested for the second time with the performance of a different group of participants at the same age tested for the first time. This twice-minus-once-tested method ...

Does personality change across the entire life course, and are those changes due to intrinsic maturation or major life experiences? This longitudinal study investigated changes in the mean levels and rank order of the Big Five personality traits in a heterogeneous sample of 14,718 Germans across all of adulthood. Latent change and latent moderated regression models provided 4 main findings: Fir...

A patient is described who developed a rapid onset of pulmonary fibrosis following treatment with a new non-steroidal anti-inflammatory drug, nabumetone. Resolution of symptoms, physical signs and radiographic changes followed drug withdrawal and steroid therapy.
