Simple motor reaction time (RT) to 100 percent negative contrast stimuli was measured for various background luminances as well as after bleaching a fraction of retinal photopigments. RT decreased to asymptotical value with the increase of background intensity. The intensity-dependent portion of RT behaved identically for 100 percent positive and negative contrast. Moreover, RT to 100 percent n...
BACKGROUND There are many causes for a large lower limb in the pediatric age group. These children are often mislabeled as having lymphedema, and incorrect diagnosis can lead to improper treatment. The purpose of this study was to determine the differential diagnosis in pediatric patients referred for lower extremity "lymphedema" and to clarify management.

BACKGROUND On the basis of a previous meta-analysis, the International Adjuvant Lung Cancer Trial was designed to evaluate the effect of cisplatin-based adjuvant chemotherapy on survival after complete resection of non-small-cell lung cancer. METHODS We randomly assigned patients either to three or four cycles of cisplatin-based chemotherapy or to observation. Before randomization, each cente...
BACKGROUND Colorectal cancer screening rates are low among poor and disadvantaged patients. Patient navigation has been shown to increase breast and cervical cancer screening rates, but few studies have looked at the potential of patient navigation to increase colorectal cancer screening rates. METHODS The objective was to determine the feasibility and effectiveness of a patient navigator-bas...
