### Measles-Containing Vaccines and Febrile Seizures in Children Age 4 to 6 YearsFebrile seizure risk 7 to 10 days after measles-mumps-rubella-varicella (MMRV) is double that of separate measles-mumps-rubella (MMR) and varicella vaccines among 1-year-olds. Whether MMRV or MMR and varicella affect febrile seizure risk among 4- to 6-year-olds has not been reported.Using Vaccine Safety Datalink data, we examined risk for febrile seizures after measles-containing vaccines. This study provides reassurance that MMRV and separately administered MMR and varicella were not associated with increased risk of febrile seizures among 4- to 6-year-olds.### Effective Analgesia Using Physical Interventions for Infant ImmunizationsPain during routine infant immunization causes parental anxiety. Oral sucrose solutions are effective pain-reduction strategies. Few studies have measured a combined strategy of a physical intervention along with sucrose to decrease the infant’s pain response.We demonstrate that a physical, nonpharmacological intervention called the 5 S’s (swaddling, side/stomach position, shushing, swinging, and sucking) provides significant pain reduction with or without sucrose during routine 2- and 4-month vaccinations.### Decreasing Prevalence of Obesity Among Young Children in Massachusetts From 2004 to 2008Following a rapid increase from 1980 to 2001, the prevalence of obesity among school-age children and adolescents in the United States has plateaued. Few studies have examined obesity trends among younger children in the past decade, and findings are inconsistent.Among children aged 6 years at this multisite pediatric practice, the prevalence of obesity was fairly stable during 1999–2003, but substantially decreased during 2004–2008. This decrease was smaller among children insured by Medicaid than children insured by non-Medicaid health plans.### Race and Unequal Burden of Perioperative Pain and Opioid Related Adverse Effects in ChildrenDisparities are known to exist in the prescription of opioid analgesics among racial and ethnic groups in the management of postoperative, cancer, and emergency department pain in patients across all ages, including children.Race is associated with an unequal burden of perioperative pain and opioid adverse effects in children. Relatively, African American children had higher postoperative pain, and Caucasian children had higher incidences of opioid related adverse effects.### Child and Adult Outcomes of Chronic Child MaltreatmentWe lack prospective studies documenting “dosage …
