Does utility of prerevision tissue biopsy sample to predict revision shoulder arthroplasty culture result in at-risk patients?
The ability for prerevision biopsy specimens of failed arthroplasties to predict the presence of bacteria at the time of revision surgery is high, although lower than previously reported. If biopsy results are used to define and predict a diagnosis of infection, the sensitivity, specificity, PPV, and NPV all significantly improve.
In line with experimental animal studies, this case suggests a clinically relevant efficacy of inhaled oxygen in patients with migraine with accompanying cranial autonomic symptoms.
