RESUMO
BACKGROUND: One of the most common and distressing side effects for cancer patients is chemotherapy-induced nausea and vomiting (CINV). New antiemetics, such as the NK-1 receptor inhibitor aprepitant, have been reported to improve control of this side effect in adults. However, little is known about its effect in the pediatric oncology population, with only a few reported cases in the literature. METHODS: This was a retrospective chart review on the use of aprepitant in the pediatric oncology population in our institution. RESULTS: Thirty-two charts and a total of 146 cycles of chemotherapy were reviewed. Mean age was 10 years. Highly emetogenic chemotherapy was used in 23/32 patients and moderately emetogenic chemotherapy in 9/32. Antiemetic regimens consisted of aprepitant+5-HT3 RA+dexamethasone (Regimen 1, 20/32 patients) or aprepitant +5-HT3 RA (Regimen 2, in 12/32). Eight out of thirty-two patients were chemotherapy-naïve and received aprepitant on their first cycle. In 24/32 patients, aprepitant was added later in their treatment, with 12/24 reporting resolution of CINV after its addition. CONCLUSIONS: Aprepitant when combined with standard antiemetics, was well tolerated in the pediatric oncology population studied. However, there is still a need to conduct prospective studies to determine the optimal efficacy of aprepitant in the pediatric oncology population.

OBJECTIVE: A preliminary study to examine the efficacy of osmotic-release oral system (OROS) methylphenidate for attention-deficit/hyperactivity disorder (ADHD) symptoms and parenting behaviors in mothers with ADHD who had children with ADHD. METHOD: Participants included 23 mother-child dyads in which both were diagnosed with DSM-IV ADHD. Mothers underwent a 5-week, double-blind titration (placebo, 36 mg/day, 54 mg/day, 72 mg/day, 90 mg/day) to an optimal dose of OROS methylphenidate, followed by random assignment to 2 weeks of placebo or their maximally effective dose. Primary outcome measures included maternal ADHD symptoms (Conners' Adult ADHD Rating Scale) and parenting (Alabama Parenting Questionnaire). Secondary outcomes included side effects ratings. Data were collected from December 2004 until August 2006. RESULTS: During Phase 1, mothers reported significant decreases in inattention (p < .001) and hyperactivity/impulsivity (p < .01) with increases in OROS methylphenidate dose. As dose increased, significant reductions in inconsistent discipline (p < .01) and corporal punishment use (p < .005) were also demonstrated. During Phase 2, small effects on inattention (d = 0.46) and hyperactivity/impulsivity (d = 0.38) were found for those randomly assigned to medication versus placebo. In addition, medium to large medication effects were found on maternal involvement (d = 0.52), poor monitoring/supervision (d = 0.70), and inconsistent discipline (d = 0.71), with small effects on corporal punishment (d = 0.42). During both phases, few adverse effects were noted. CONCLUSIONS: OROS methylphenidate was well tolerated and was associated with significant improvement in maternal ADHD symptoms and parenting. Variable effects on parenting suggest that behavioral interventions may be necessary to address impairments in parenting among adults with ADHD.
