All 4 faces pain scales were found to be adequately supported by psychometric data .
When given a choice between faces scales , children preferred the WBFPRS .
Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS .
: For clinical use , we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use .
CONTEXT : Numerous faces scales have been developed for the measurement of  pain intensity in children .
It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity , reliability , feasibility , and preference .
OBJECTIVES : To summarize and systematic ally review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility .
Platelet-rich plasma for pediatric tonsillectomy patients.
OBJECTIVES /HYPOTHESIS To determine if placement of autologous platelet-rich plasma ( PRP ) on the tonsil beds at the time of tonsillectomy would decrease postoperative pain and complications . STUDY DESIGN Double blind , r and omized , prospect i ve study . METHODS Seventy children were recruited to participate in the study , ranging in age from 4 to 15 years . They were r and omized to treatment ( PRP ) or control groups . The parents , patients , and nurses were blinded as to which group they were in . Postoperative pain scores were obtained using the FACES pain scale and recorded in a home diary . RESULTS Seventy patients were recruited to the study , and 12 did not su bmi t their diaries and were considered to drop out of the study . Demographic data were similar for both control and treatment groups . Median pain scores , medication use , days to normal diet , and office visits did not differ between the two groups . CONCLUSIONS PRP applied once at the time of tonsillectomy does not improve postoperative pain or recovery in pediatric patients
