A Rotated and Laterally Displaced Patellar Dislocation.

Background: Patellar dislocations are a common orthopedic emergency with several variants. The rarer variants include rotational dislocations. These often require open reduction in the operating room.

Prevalence of Staphylococcus aureus nasal colonization in emergency department personnel.

Study Objective: Nasal colonization with Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) can precede infection in patients and contacts. Although general population S aureus/MRSA rates are well described, the prevalence of S aureus and MRSA nasal colonization in emergency department health care workers is not defined. We seek to determine the prevalence of S aureus and MRSA nasal colonization among ED health care workers without evidence of an active site of staphylococcal infection and identify variables associated with colonization.

Combining clinical risk with D-dimer testing to rule out deep vein thrombosis.

We sought to determine whether the combination of low-intermediate clinical risk of acute lower extremity deep vein thrombosis (DVT) and negative ELISA D-dimer assay can eliminate the need for duplex ultrasonography. Three hundred thirty-six patients prospectively underwent clinical risk stratification (low, intermediate, and high), D-dimer testing, and duplex ultrasonography. Thirteen of 145 intermediate-risk patients had acute DVT; 11 (85%) had a positive D-dimer.
