Comparative Study
Differentiation of nonperforated from perforated appendicitis: accuracy of CT diagnosis and relationship of CT findings to length of hospital stay.
To determine retrospectively the sensitivity and specificity of computed tomographic (CT) signs in differentiating acute nonperforated appendicitis from perforated appendicitis and to compare CT findings with the length of hospital stay. ⋯ Extraluminal air and moderate or severe periappendiceal inflammatory stranding are statistically significant independent predictors for appendiceal perforation and are associated with increased hospital stay.

To evaluate the use of transcatheter arterial embolization (TAE) in hemodynamically unstable patients with blunt splenic injury in whom there is a transient response to initial fluid resuscitation. ⋯ TAE for blunt splenic injury can be performed successfully even in hemodynamically unstable patients with a transient response to initial fluid resuscitation.

To retrospectively evaluate dose-volumetric parameters for association with risk of severe (grade >/=3) radiation pneumonitis (RP) in patients after three-dimensional (3D) conformal radiation therapy for lung cancer. ⋯ MLD is a useful indicator of risk for development of severe RP after 3D conformal radiation therapy in patients with lung cancer.
