Pneumothorax (PTX) in patients with penetrating thoracic trauma is routinely ruled out with serial chest radiographs (CXRs). This study examined the efficacy of a shortened time period between initial and follow-up radiographs. Patients with penetrating torso injuries treated at a Level-1 trauma center received a CXR during their initial evaluation. ⋯ One patient had a normal initial CXR, but developed a PTX on the 3-h film, requiring tube thoracostomy. No patients developed a PTX on the 6-h study that was not present on the initial or 3-h CXR. In conclusion, extending the time between initial and final CXRs to 6 h in patients with penetrating thoracic trauma provided no additional information that was not available on the 3-h film.

Multicenter Study Clinical Trial
A prospective multicenter trial testing the SCOTI device for confirmation of endotracheal tube placement.
We sought to characterize the Sonomatic Confirmation of Tracheal Intubation (SCOTI) device's ability to confirm endotracheal tube location during real-time intubation in emergency and elective settings. Data were prospectively collected during a multicenter convenience-sample observational trial of emergency and elective intubation cases. In addition to tracheal and inadvertent esophageal intubations in emergency patients, intentional esophageal intubations were also performed to improve specificity calculations in consenting elective surgical patients. ⋯ We conclude that the SCOTI device has high sensitivity and specificity for tube placement confirmation during tracheal intubation attempts in both emergency and elective settings. It also facilitates tube placement itself during difficult intubations. As such it may be considered an adjunctive device to minimize the potentially fatal complication of esophageal intubation.

The differential diagnosis of left lower quadrant abdominal pain in an adult man includes, among others, sigmoid diverticulitis; leaking abdominal aortic aneurysm; renal colic; epididymitis; incarcerated hernia; bowel obstruction; regional enteritis; psoas abscess; and in this rare instance, situs inversus with acute appendicitis. We report a case of situs inversus totalis with left-sided appendicitis and a brief review of the literature. There were several subtle indicators of total situs inversus present that were missed by the physicians and surgeons who initially evaluated the patient prior to surgery. Computed tomography scan with contrast, however, revealed the diagnosis immediately, and treatment was successfully initiated.
