ABSTRACT
PURPOSE: The aim of this study was to investigate the prevalence of acute low back pain (ALBP) and associated factors in high school students from a Southern Brazilian city. METHODS: The study was cross-sectional and interviewed 1,233 students 13- to 19-year-olds, attending high schools. A total of 25 schools were included in the sample (15 state institutions, 7 private, 2 federal and 1 municipal). The ALBP was evaluated using two questions. The outcome was LBP in the previous 30 days. RESULTS: The prevalence of ALBP was 13.7%. Non-white students, who commuted to school walking, showed a higher prevalence of ALBP. The prevalence of ALBP is relatively high. CONCLUSIONS: Further studies with follow-ups to adulthood are needed to investigate whether physical cumulative loads on the lumbar spine (for example, duration/transport, school bags and inadequate school furniture) during adolescence, may influence the development of ALBP later in life.

O menisco discóide é uma condiçäo na qual a estrutura fibrocartilagínea do joelho tem a forma discóidea ao invés de seminular. Isso se verifica usualmente no compartimento lateral do joelho, mas pode ocorrer no compartimento medial. Geralmente é unilateral, mas pode ser bilateral e ocorre com igual freqüência em meninos e meninas. A etiologia do menisco discóide é controvertida e várias classificaçöes säo propostas. Esta condiçäo é muito rara. Os autores acompanharam um paciente com menisco discóide lateral do tipo ligamento de Wrisberg, no qual há uma modalidade meniscal anormal. O paciente estava sintomático e apresentava a assim chamada "síndrome do snapping (estalido) do joelho". O paciente foi submetido a meniscectomia lateral por artrotomia.
