Unlabelled: Functional mobility of children with cerebral palsy (CP) is influenced by personal and environmental factors, serving as barriers and/or facilitators and impacting on children's strategies and functional outcome., Objectives: To describe typical mobility methods used by children with CP at home, school and community and to compare them across family's socioeconomic levels (SES)., Methods: The Functional Mobility Scale was used to assess mobility of 113 children with CP of high and low SES at home, school, and community., Results: Differences in mobility methods of participants classified as Gross Motor Function Classification System levels II, III and IV were found between home and community. For levels III and IV, differences were also found between home and school. At home, participants from higher SES used wheelchairs more frequently while those from lower SES used floor mobility (crawling)., Conclusions: Environmental settings and families' socioeconomic status influence mobility and use of mobility devices by children with CP.

Periapical lesions, as well as periodontal disease, seems to have cyclic patterns of evolution. Periods of burst may be intercalated with periods of quiescence. Because keratinocyte division must occur during cyst growth, it is presumed that epithelium status could indicate the biological activity of radicular cysts (RCs). Th1 and Th2 are important heterogeneous stages of lymphocyte differentiation. Delayed-type hypersensitivity immune reactions are mediated by Th1 lymphocytes, whereas Th2 populations mediate some types of humoral immune response. Th2 lymphocytes are characterized by high expression of CD30 glycoprotein. Th1 and Th2 lymphocytes have not been evaluated in periapical inflammatory lesions. The purpose of this study was to evaluate CD30+ cells in RCs with atrophic and hyperplastic epithelium. A biotin-streptavidin amplified system was used for identification of CD30 receptor. Results demonstrate increased proportions of Th2 cells in cysts with hyperplastic epithelium. Our results suggest that Th2 cells could be associated with RC growth.
