Effect of oral antibiotics after two-stage revision for periprosthetic joint infection on subsequent antibiotic resistance within a national cohort of United States veterans.

: Prior studies have indicated that administration of prolonged courses of oral antibiotics after Stage 2 reimplantation surgery for periprosthetic joint infection (PJI) results in a lower rate of recurrent PJI. However, there is concern that this antibiotic usage results in an increased risk of antibiotic resistance in any subsequent PJI that does occur. : We retrospectively reviewed patients who underwent Stage 2 reimplantation surgery for PJI within the national Veterans Affairs hospital system of the United States.

Bradycardia in a Man With Hypertension.

A man without cardiac symptoms was found to have a slow irregular pulse, and an electrocardiogram revealed sinus bradycardia with escape-capture bigeminy. He was taking verapamil, clonidine, and hydralazine for hypertension. The verapamil was discontinued; he returned to normal sinus rhythm and was discharged on the second hospital day.

Predictors of in-hospital mortality and complications in very elderly patients undergoing emergency surgery.

Introduction: With the increasing aging population demographics and life expectancies the number of very elderly patients (age ≥ 80) undergoing emergency surgery is expected to rise. This investigation examines the outcomes in very elderly patients undergoing emergency general surgery, including predictors of in-hospital mortality and morbidity.

Methods: A retrospective study of patients aged 80 and above undergoing emergency surgery between 2008 and 2010 at a tertiary care facility in Canada was conducted.
