Relatively little is known about the longer-term impact of traumatic brain injury (TBI) on children's daily functioning, especially the broader outcome domain referred to as health-related quality of life (HRQL). The objective of the present study was to examine the nature and predictors of HRQL outcomes in children with moderate to severe TBI an average of 4 years postinjury. ⋯ Findings underscore the importance of using comprehensive measures of HRQL, along with traditional indicators of functional outcomes, when evaluating the longer-term impact of injuries in children. Identification of predictors suggests the need for close monitoring and intervention of high-risk children.

To investigate underascertainment of unexpected infant deaths at the national level as a result of probable classification as attributable to unknown cause. ⋯ Risk profiles indicate that deaths of unknown cause are likely to represent a mixture of unexpected deaths. The process for determination of cause of unexpected death affects national underascertainment of SIDS and injury deaths. Better coordination among child fatality review teams and local, state, and national officials should reduce underascertainment and improve documentation of circumstances surrounding deaths for prevention efforts.

Randomized Controlled Trial Clinical Trial
A randomized trial of moderately early low-dose dexamethasone therapy in very low birth weight infants: dynamic pulmonary mechanics, oxygenation, and ventilation.
Dexamethasone is used in very low birth weight (VLBW) ventilator-dependent infants to prevent or decrease the severity of chronic lung disease. We reported a significant increase in respiratory compliance during a 7-day weaning course of moderately early dexamethasone therapy (0.5 mg/kg/d) in VLBW infants, along with a shorter duration of mechanical ventilation and O2 supplementation. Although 0.5 mg/kg/d has been the most commonly used dose in preterm infants, the use of a lower dose of dexamethasone may reduce potential adverse effects of steroid therapy. Quantification of dynamic pulmonary mechanics in VLBW infants who receive low-dose dexamethasone has not been reported. The objective of this study was to compare the effect of 2 dose regimens of dexamethasone on dynamic pulmonary mechanics, mean airway pressure (MAP), and fractional inspired oxygen concentration (Fio2) in intubated VLBW infants who were at risk for chronic lung disease. ⋯ Our findings indicate that 1) comparable significant increases in Crs are present in the low-dose dexamethasone as well as the high-dose dexamethasone groups on days 2, 5, and 7 of steroid therapy; and 2) MAP and Fio2 are significantly decreased during dexamethasone therapy in both groups of infants. We conclude that low-dose and high-dose dexamethasone, as used in this study, have comparable beneficial effects on dynamic pulmonary mechanics and subsequently on oxygen requirement and applied ventilatory support in VLBW infants.

Comparative Study
Pediatric residents' career intentions: data from the leading edge of the pediatrician workforce.
To determine factors influencing career choices by pediatric residents and how they may change the future pediatric physician workforce. ⋯ With a projected increase in the number of female pediatricians and a decline in international medical graduates, our study suggests that pediatrics may continue to shift toward an increased proportion of general pediatricians. Lifestyle issues are a major factor influencing job choice and must be addressed.

The Functional Independence Measure (WeeFIM) for children is a simple-to-administer scale for assessing independence across 3 domains in American children. WeeFIM was based on a conceptual framework by the World Health Organization (1980) of pathology, impairment, disability and handicap, and the "burden of care." WeeFIM is useful in assessing functional independence in children aged 6 months to 7 years. It can be used for children with developmental disabilities aged 6 months to 21 years. Normative WeeFIM data had been validated for American children. Because of cultural and environmental differences among countries, normative data for the Chinese population are needed. With a normative database, the progression of independence at home and in the community can be evaluated. WeeFIM is an 18-item, 7-level ordinal scale instrument that measures a child's consistent performance in essential daily functional skills. Three main domains (self-care, mobility, and cognition) are assessed by interviewing or by observing a child's performance of a task to criterion standards. WeeFIM is categorized into 2 main functional streams: "Dependent" (ie, requires helper: scores 1-5) and "Independent" (ie, requires no helper: scores 6-7). Scores 1 (total assistance) and 2 (maximal assistance) belonged to the "Complete Dependence" category. Scores 3 (moderate assistance), 4 (minimal contact assistance), and 5 (supervision or set-up) belonged to the "Modified Dependence" category. Scores 6 (modified independence) and 7 (complete independence) belonged to the "Independent" category. The WeeFIM is a 7-level criterion-specific ordinal scale. Level 7 requires no assistance for the child and the child completes the task independently without requiring a device. During the task, there is no concern about safety or taking an inordinate amount of time. Level 6 reflects modified independence and includes use of an assistive device or not completing the task in a timely or safe manner. ⋯ We have created a normative functional independence profile for Chinese children by adapting the American-based WeeFIM. There were cultural differences when compared with American children. Interestingly, Chinese children in Hong Kong scored better than their American counterparts in domain 1 (self-care) in all ages. This might be attributable to early attendance in preschool settings where children are taught to tend to their needs. Even for domain 2 (mobility), the higher scores in younger Chinese children in Hong King (<3 years) might be explained by earlier attendance in preschool settings. The American children did catch up after 3 years. As for domain 3 (cognition), the local educational system emphasized reading, writing, memorizing materials, and social interaction. Thus, Chinese children in Hong Kong had better cognition scores until 42 months, when their American counterparts caught up by attending preschool. There are definitely environmental and cultural practices affecting functional independence in both ethnic groups, especially in the upper age range (>4 years) both in America and Hong Kong. Thus, a locally validated WeeFIM instrument should be adopted for Chinese children. Our study demonstrated that WeeFIM could be used as a functional independence measure for Chinese children. Hong Kong has a different cultural background compared with America; thus, usage of WeeFIM with different age criteria for achieving independence should be adopted.
