Controversy exists on whether the constructs tested by paper/pencil and computerized continuous-performance tests (CPT) are similar, and the deficits recorded in children with attention-deficit/hyperactivity symptoms (ADHD) are comparable. Signal-detection measures were recorded on four such tests of 'sustained attention', with increasing working-memory requirements in healthy children (14; mea...

The penetration of objects into the orbit can lead to blindness and even to the death of the patient. The penetration of organic objects longer than 7 cm into the eye is a rare phenomenon. In this study, we report a case in which a 6-year-old boy fell on a pencil which penetrated the upper side of his right eye orbit. Because of the agitation of the child and the lack of access, it was not poss...

Many recent keypoint detectors associate a local scale (for multiscale detectors) or even a full affine frame (for affine-invariant detectors) to each detected keypoint. Although conventional epipolar constraints are a powerful tool for matching point-like features between pairs of images, they provide no constraint on their relative scales. We present an enhanced epipolar constraint that explo...

BACKGROUND Memory and attention are two cognitive domains pivotal for the performance of instrumental activities of daily living (IADLs). The assessment of these functions is still widely carried out with pencil-and-paper tests, which lack ecological validity. The evaluation of cognitive and memory functions while the patients are performing IADLs should contribute to the ecological validity of...

OBJECTIVES To explore the relationship between executive function (EF) and social skills in youth with sickle cell disease (SCD).  METHODS  20 youth with SCD completed objective tests of EF (Tasks of Executive Control; Animal Sorting subtest from the Developmental Neuropsychological Assessment-Second Edition), an IQ screener, and paper-and-pencil measures of social skills (Social Skills Impro...
