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 .
Nasal sumatriptan is effective in treatment of migraine attacks in children
Objective : To investigate the efficacy of nasal sumatriptan in migraine attacks of children and adolescents . Methods : A double-blind , placebo-controlled , two-way crossover trial was conducted in three hospital outpatient departments , with 8 to 17 year olds diagnosed with migraine serving as subjects ( International Headache Society 1988 ) . A single dose of sumatriptan nasal spray and a matching placebo were administered at home during two attacks . The sumatriptan dose was 10 mg for a body weight of 20 to 39 kg and 20 mg for those with a body weight of ≥40 kg . The primary efficacy endpoint was headache relief by two grade s on a 5- grade face scale at 2 hours . Results : Eighty-three patients used both treatments and 11 only the first . At 2 hours , the primary endpoint was reached nearly twice as often after sumatriptan ( n = 53/83 ; 64 % ) as after placebo ( n = 32/83 ; 39 % ) ( p = 0.003 ) . Already at 1 hour , headache relief was seen more often after sumatriptan ( n = 42/83 ; 51 % ) than after placebo ( n = 24/83 ; 29 % ) ( p = 0.014 ) . The difference was even more obvious in patients who received the 20-mg dose as well as in the intention-to-treat analyses ( n = 94 ) . Other endpoints , including child ’s preference and using rescue medication , also favored sumatriptan . The most common adverse effect was a bad taste  after sumatriptan , reported in 29 % ( n = 26/90 ) of the attacks . No serious adverse effects were observed . Conclusion : Nasal sumatriptan is an effective and well-tolerated treatment for migraine attacks in children over 8 years of age
