Do women with patellofemoral pain syndrome have quadriceps femoris volume and strength deficiency?
decreased torque, total volume, and CSA of the quadriceps muscle are presented in unilateral with PFPS although cause or effect cannot be established. Large prospective longitudinal studies are needed to detect the changes in the muscle structure and to establish whether these features are a cause of PFPS.
A simulation-based mastery learning program increased residents' skills in simulated central venous catheter insertion and decreased complications related to central venous catheter insertions in actual patient care.
