Do revisions of monoblock metal-on-metal THAs have high early complication rates?
Complications and reoperations occur frequently after revision for failed monoblock metal-on-metal THA (20% and 16%, respectively), and older patients appear to be at greater risk for complications after these revisions. Aseptic loosening, deep infection, and instability are all of great concern after revision and surgeons should be aware of these potential complications when undertaking revision of these THAs.
Our results suggest the importance of panic symptom profiles in determining respiratory responses to a hypoxic challenge in patients with panic disorder. These findings are discussed in light of current theories of panic disorder, with particular attention to respiratory disturbances in this disorder.
