ABSTRACT
Best evidence has no bearing on quality of life if it is not implemented in clinical practice. The authors introduce knowledge translation as a theoretical framework for closing the gap between evidence and practice in plastic surgery. The current state of published evidence in plastic surgery is reviewed and evaluated, with the recommendation to use the EQUATOR Network's guidelines for reporting clinical research findings. Tools and strategies are offered for the reader to understand and integrate evidence at the bedside. Systemic solutions are also proposed for the dissemination of best evidence to facilitate its translation into practice.

This study investigated whether the serotonin 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) can induce compulsive checking in a large open field, as does the dopamine D2/D3 receptor agonist quinpirole. To induce compulsive checking, male rats were exposed to eight injections of either 8-OH-DPAT (1 mg/kg), quinpirole (0.2 mg/kg), or saline. Subsequently, to assess cross-sensitization, rats received an acute challenge of 8-OH-DPAT or quinpirole. The results showed that treatment with 8-OH-DPAT induces compulsive checking and may have a stronger effect on this behavior compared with quinpirole. However, there was no cross-sensitization between 8-OH-DPAT and quinpirole on measures of compulsive checking and locomotion. Moreover, the spatial distribution of locomotor paths in 8-OH-DPAT animals was more confined and invariant than in quinpirole rats; their rate of locomotor sensitization was also faster than that in quinpirole animals. Thus, although 8-OH-DPAT and quinpirole can induce compulsive checking in a large open field, the results suggest that they do so differently. It is suggested that 8-OH-DPAT and quinpirole probably produce compulsive behavior by acting on different parts of a security motivation circuit underlying obsessive-compulsive disorder. Quinpirole may induce compulsive checking behavior by directly driving dopaminergic activity mediating the motivational drive to check. Conversely, 8-OH-DPAT may perpetuate the activated motivational state by inhibiting the serotonergic-negative feedback signals that normally deactivate the obsessive-compulsive disorder circuit.
