Oral Health-Related Quality of Life in Patients with Rheumatoid Arthritis.

Introduction: The assessment of the quality of life (QOL) in rheumatoid arthritis (RA) patients is of great importance for health researchers, health planners, and clinical specialists. Thus, the present study aimed to evaluate the oral health-related quality of life in patients with RA.

Materials And Methods: In this case-control study, data were collected by two standard questionnaires filled by 80 patients with rheumatoid arthritis and 80 healthy individuals.

Optimal detection of visual evoked potentials.

We consider the problem of detecting visual evoked potentials (VEP's). A matched subspace filter is applied to the detection of the VEP and is demonstrated to perform better than a number of other evoked potential detectors. Unlike single-harmonic detectors, the matched subspace filter (MSF) detector is suitable for detecting multiharmonic VEP's.
