Research paper thumbnail of Computed tomography pulmonary angiography in the diagnosis of acute pulmonary embolism in the emergency department

The files and computer records of 850 patients older than 16 years of age who were seen in the Hacettepe University Hospital ED between April 10, 2001, and December 1, 2005, and who required CTPA for PE prediagnosis and/or another diagnosis, were studied retrospectively. PE was identified by CTPA in 9.4% of 416 women and in 5.8% of 434 men. A significant difference (P<.05) was noted in the women and men in whom PE was detected. The mean age of the patients was 58.13±17.88 y (range, 16-100 y). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for clinical susceptibility to PE among patients who underwent CTPA were assessed at 95.3%, 48.2%, 13%, and 99.2%, respectively. CTPA was done for different reasons: aortic aneurysm dissection (n=1), cough distinctive diagnosis (n=1), dyspnea distinctive diagnosis (n=6), chest pain distinctive diagnosis (n=3), PE prediagnosis (n=51), and other reasons (n=2). Also, sensitivity, specificity, PPV, and NPV were found to be 95.4%, 16.2%, 14.4%, and 96%, respectively, for D-dimer. CTPA, which is accessible on a 24-h basis in the ED, is a valuable tool for the diagnosis of PE.

However, mechanical or functional causes may also lead to this pathology. Acute GOO is characterized by delayed gastric emptying, anorexia, or nausea accompanied by vomiting. Herein we report a 56-year-old man diagnosed with GOO secondary to paraesophageal hiatal herniation of gastric antrum after laparoscopic fundoplication. Because of the rarity of this disease, common gastrointestinal complaints may mislead the emergency physician to diagnose a nonsurgical gastrointestinal disease if a detailed history and physical examinations are not obtained.

We report a patient with rapid-onset hemodynamically unstable rectus sheath hematoma in conjunction with receiving anticoagulation therapy. A 54-year-old woman was admitted to the emergency department, complaining with a 4-hour history of sudden severe right upper abdominal pain. She had been using warfarin and diltiazem. There was no finding at ultrasonography in admission. At the second hour of followup, re-examination revealed an elongated tender mass in the right abdomen and little bluish discoloration at the same area, and Hb and Hct levels had dropped and the patient become hemodynamically unstable. Abdominal computed tomography showed the mass correlated with anatomic position of the rectus sheath. Rectus sheath hematoma may occur more frequently than previously described in relatively elderly patients. The classic signs of localized tenderness or mass with a characteristic history of straining may be completely absent. The diagnosis can be made confidently by urgent computed tomography scanning especially in patients without mass; ultrasonography may miss the diagnosis in early stages. www.elsevier.com/locate/ajem 0735-6757/$see front matter

Pneumorrhachis can be classified as epidural or subarachnoid space pneumorrhachis.
