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 .
Evaluation of early postoperative morbidity in pediatric tonsillectomy with the use of sucralfate.
OBJECTIVE The objective of this study is to evaluate the efficacy of sucralfate in alleviating posttonsilectomy morbidity in a pediatric group of patients . METHODS A prospect i ve , double-blind , r and omized , and placebo-controlled study comparing the irrigation of a solution containing either 1 g of sucralfate ( study group ) or 1 g of lactulose ( control group ) was performed on 69 children aged 3 - 12 years , who underwent tonsillectomy at the University Hospital of Brasilia Medical School . The children were r and omly assigned and each one used a solution containing sucralfate or lactulose to swish and swallow four times daily during 7 days . Eleven patients were excluded . The anesthetic was st and ardized and no premedication was used . Pain magnitude using an " Oucher " scale , nausea , vomiting , bleeding , earache , analgesic drug intake , changes in the interincisor teeth distance , and changes in the weight and temperature were assessed by the surgeon 6 , 24h , and 7 days after the surgery . RESULTS Patients in the study group had significantly lower pain scores in the initial 6 postoperative hours ( p<0.05 ) . The difference between the two groups was not statistically significant for the other periods following the procedure or on the evaluation of the other indices . CONCLUSIONS The use of the sucralfate in pediatric patients undergoing tonsillectomy was not effective in reducing the postoperative morbidity according to the parameters used in this study . The surgical technique with careful mucosal dissection associated with postoperative caries could be more important in the reduction of posttonsilectomy morbidity
