Corticosteroids can reduce pain but the optimal dose and safety profiles are still uncertain. This study aimed to evaluate two different doses of dexamethasone for pain management and their side effects after total knee arthroplasty. A prospective randomised, controlled trial. A tertiary teaching hospital in Hong Kong. One hundred and forty-six patients were randomly allocated to one of three study groups. Before operation, patients in group D8, D16 and P received dexamethasone 8 mg, dexamethasone 16 mg and placebo (0.9% saline), respectively. The primary outcome was postoperative pain score. Secondary outcomes were opioid consumption, physical parameters of the knees and side effects of dexamethasone. Compared with placebo, group D16 patients had significantly less pain during maximal active flexion on postoperative day 3 [-1.3 (95% CI, -2.2 to -0.31), P = 0.005]. There was also a significant dose-dependent trend between pain scores and dexamethasone dose (P = 0.002). Compared with placebo, pion of the knee was found. ClinicalTrials.gov identifier NCT02767882.

However, the impact of SMF on perceptions of social traits has not been well studied. To characterize the impact of SMF on external value judgments in adults in the United States. Respondents completed an online survey in which they reacted to statements about individuals with varying grades of SMF. Attributes were rated on a scale from 0 to 100 with higher scores for more positive attributes. Similar proportions of respondents (N = 1996) indicated that women and men with double chins were less attractive than those without (91% and 90%, respectively). A double chin was more likely to be noticed on a woman than on a
