Comparative Study
The study of plate-screw fixation in the posterior wall of acetabulum using computed tomography images.
The article aims to delineate the width of posterior column, the thickness of posterior wall, and safe angles for screw placement in the posterior wall to avoid intraarticular screw penetration. ⋯ The oblique multiplanar reconstruction images perpendicular to the surface of posterior column were selected to describe the safe angle for screw insertion into posterior wall, which can provide consistent results in both specimens and volunteers. The method can be applied in practice both on acetabular specimens and operative cases and is helpful to make individual perioperative planning for safer fixation of posterior wall fracture.

Comparative Study
Cardiopulmonary effects of matching positive end-expiratory pressure to abdominal pressure in concomitant abdominal hypertension and acute lung injury.
To evaluate the cardiopulmonary effects of positive end-expiratory pressure (PEEP) equalization to intra-abdominal pressure (IAP) in an experimental model of intra-abdominal hypertension (IAH) and acute lung injury (ALI). ⋯ Simultaneous IAH and ALI produce important impairments in the respiratory physiology. PEEP equalization to AP may improve the respiratory performance, nevertheless with a secondary hemodynamic derangement.

The significance of serial white blood cell (WBC) counts in trauma patients with a suspected hollow viscus injury (HVI) is unknown. The purpose of this study was to examine the role of serial WBC counts in the diagnosis of a HVI. ⋯ Multiple variables likely impact the WBC count in trauma patients. WBC count elevation on admission is nonspecific and does not predict the presence of a HVI. With serial measurements, WBC counts >or=20.0 are independently associated with a HVI, whereas counts
