Pulmonary ossifications are classified as either dendriform or nodular, according to their histologic appearance. Both seem to be distributed similarly and are often confined to the lower lobes of the lung. These ossifications may be included in the differential diagnosis of a solitary pulmonary nodule.

The RIFLE (risk, injury, failure, loss, and end-stage renal disease) classification system was developed to standardize the definition of acute kidney injury (AKI) in adults. We hypothesized that AKI was associated with increased mortality and morbidity. ⋯ Acute kidney injury was independently associated with an increased occurrence of postoperative complications but not with mortality after pediatric cardiac surgery.

Chest computed tomography (CCT) is a method of screening for intrathoracic injuries in hemodynamically stable patients with penetrating thoracic trauma. The objective of this study was to examine the changes in utilization of CCT over time and evaluate its contribution to guiding therapeutic intervention. ⋯ The use of CCT for penetrating thoracic trauma increased 3.5-fold during the study period with a concurrent increase in findings of uncertain clinical significance. Patients with a normal screening CXR should be triaged with 3-hour delayed CXR, serial physical examinations, and focused assessment with sonography for trauma; and CCT should only be used selectively as a diagnostic modality.

Off-pump coronary artery bypass graft (OPCAB) may be associated with improved hospital outcomes compared with on-pump coronary artery bypass graft. However, intraoperative conversion to on-pump coronary artery bypass graft has been associated with adverse outcomes. The purpose of this study was to identify preoperative risk factors for intraoperative conversion in nonemergent patients undergoing isolated OPCAB. ⋯ Conversion to cardiopulmonary bypass during OPCAB is associated with increased in-hospital and long-term mortality and may be related to surgeon experience. Recognition of the preoperative risk factors associated with an increased risk of conversion may allow for better patient selection and reduce the incidence of intraoperative conversion during OPCAB.

Despite recent studies reporting on the results of prospective intentional sublobar resection for patients with small non-small cell lung cancer (NSCLC), few studies have investigated predictors for prognosis or recurrence exclusively in patients undergoing intentional sublobar resection. ⋯ The factors related to upstaging on pathologic diagnosis were not identified as independent predictors; therefore, the current patient selection criterion seems reasonable. If lymphatic permeation is present on pathologic findings, careful follow-up is recommended. The predictors identified in this study will support assessment and interpretation of the results of ongoing prospective randomized trials of lobar versus sublobar resection in patients with small peripheral NSCLC.
