Rural-urban comparisons of dengue seroprevalence in Malaysia.

Background: Each year an estimated 390 million dengue infections occur worldwide. In Malaysia, dengue is a growing public health concern but estimate of its disease burden remains uncertain. We compared the urban-rural difference of dengue seroprevalence and determined age-specific dengue seroprevalence in Malaysia.

Monitoring the quality of robot-assisted pedicle screw fixation in the lumbar spine by using a cumulative summation test.

Study Design: Prospective randomized controlled trial.

Objective: The aim of this study was to monitor the quality control of robot-assisted pedicle screw fixation accuracy by using a cumulative summation (CUSUM) test at the initial stage of its application.

Summary Of Background Data: Although robot-assisted pedicle screw fixation reduces screw misplacement rates and provides critical support for minimally invasive surgical procedures, there have been no reports relating to the monitoring of quality control of the accuracy of this robot-assisted pedicle screw fixation procedure.
