“…[3][4][5] This type of prosthesis has also been used for osteoarthritis. [4][5][6][7][8][9][10][11] Migration of the outer head has been reported soon after operation for dysplastic osteoarthritis. 5,10,12 Extensive migration will lead to limb-length discrepancy, loss of acetabular bone stock, and increased technical difficulty of conversion to THA.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…In cases of endoprosthesis implantation, it is possible to choose between two general types: bipolar (BPEP) and total (TEP) hip endoprosthesis. BPEP, following unipolar hip endoprosthesis, was first introduced in 1974 (13) to reduce the friction between the acetabular cartilage and the prosthesis (14)(15)(16). When comparing BPEP and the Austin-Moore (unipolar) hip endoprostheses, some authors (8,17,18) found that BPEP may give superior results, while other authors (12,19,20) found that unipolar and bipolar hip endoprosthesis are essentially the same regarding dislocation and other parameters.…”
