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 .
Topical Clindamycin in Post-Adenotonsillectomy Analgesia in Children: A Double-Blind, Randomized Clinical Trial
OBJECTIVES : Tonsillectomy , with or without adenoidectomy , is one of the most common surgical procedures in pediatric otolaryngology . Pain is the main cause of morbidity in the postoperative period , where it is serious in some cases , leading to odynophagia and result ant complications such as dehydration . We evaluated the effect of topical clindamycin in the reduction of oropharyngeal pain in children who underwent adenotonsillectomy .  Secondary outcomes were otalgia , analgesic use , oral bacterial count , type of diet , secondary bleeding , vomiting , fever , and weight loss . STUDY DESIGN : Double-blind , r and omized clinical trial . SETTING : Tertiary hospital . SUBJECTS AND METHODS : Eighty-two children of both sexes between four and 12 years of age who underwent adenotonsillectomy were allocated to receive topical clindamycin or placebo in the immediate preoperative , intraoperative , and eight-to12-hours postoperative periods . Pain was measured using a faces pain scale for five days . RESULTS : Reduction of oropharyngeal pain was significant with the use of clindamycin only on the first postoperative day ( 95 % confidence interval , 2.22 to 4.41 [ clindamycin ] vs 4.53 to 6.3 [ placebo ] ; P = .002 ) . No difference was observed in the aerobic and anaerobic counts by tongue swab between premedication and third-postoperative-day samplings . There were no differences with respect to reduction in otalgia , paracetamol use , return to normal diet , variation in weight , secondary hemorrhage , vomiting , and fever . CONCLUSION : The use of topical clindamycin was beneficial in reducing pain on the first postoperative day , without effect on subsequent days . Future investigations could examine the use of topical clindamycin not only in the first 12 hours but also during five days of follow-up
