The aim of this study was to determine the prevalence of self-reported chronic idiopathic pain among adolescents in relation to age and gender, and to explore how pain interferes with daily activities. The study was performed in Nord-Trøndelag County, Norway in 2006-2008. All adolescents were invited to participate; the response rate was 78%. Participants(More)
The aim of this study was to survey the occurrence of invasive group B streptococcus (GBS) disease in Norway and detect possible trends in characteristics of invasive GBS strains from1996 to 2006. Data from national monitoring systems for infectious diseases in Norway were analysed. Of 638,452 live births in the period, 434 cases of invasive GBS disease in(More)
OBJECTIVE To study the incidence and prevalence of juvenile chronic arthritis (JCA) in northern Norway. METHODS Cases from the period 1985-1994 were retrospectively identified from the hospital files of the only pediatric department treating JCA in the study area. The European League Against Rheumatism (EULAR) criteria for JCA were used. RESULTS The(More)
OBJECTIVE To compare the juvenile arthritis disease activity score (JADAS) based on C reactive protein (CRP) (JADAS-CRP) with JADAS based on erythrocyte sedimentation rate (ESR) (JADAS-ESR) and to validate JADAS in a population-based setting. METHODS The CRP and ESR values and the corresponding JADAS scores (JADAS10/27/71) were compared in a longitudinal(More)
OBJECTIVES To examine a possible association of parental chronic pain with chronic pain in the adolescent and young adult and to explore whether a relationship could be explained by socioeconomic and psychosocial factors or may be affected by differences in family structure. DESIGN Unselected, population-based, cross-sectional study. SETTING(More)
Group B streptococcus (GBS) is an important aetiological agent of serious neonatal infections. A rapid and sensitive method for the detection of GBS colonization in pregnant women at delivery could make intrapartum screening for GBS possible. A real-time PCR method targeting the sip gene of GBS in pregnant women at delivery has been evaluated. The(More)
OBJECTIVE To describe the disease characteristics, long-term course, and outcome of patients with juvenile idiopathic arthritis (JIA) in a population-based setting. METHODS Consecutive cases of JIA from defined geographic areas of Denmark, Finland, Sweden, and Norway in whom disease onset occurred in 1997-2000 were included in a prospective, multicenter(More)
OBJECTIVE To study the predictive value of antinuclear autoantibody (ANA) tests and antihistone antibodies (AHA) as risk factors for development of chronic asymptomatic uveitis of insidious onset in juvenile idiopathic arthritis (JIA). METHODS ANA by indirect immunofluorescence using HEp-2 cells (IF-ANA), ELISA for ANA (E-ANA), and AHA were analyzed in(More)
OBJECTIVE The general movement assessment (GMA) method is used to predict cerebral palsy (CP) in infants with high risk of developing neurological dysfunctions. Most of the work on GMA has been performed from the same group of researchers. The aim of this study was to demonstrate to what extent GMA predicted CP in our hands. METHOD A prospective study was(More)
UNLABELLED The aim of this study was to assess the association of chronic pain with different lifestyle factors and psychological symptoms in a large, unselected adolescent population. Pain was evaluated as chronic non-specific pain, chronic multisite pain, and in additional analyses, chronic pain with high disability. The study was performed during 2006 to(More)
