METHODS: In order to study the regulation of HBV variants in the vicinity of the NRRE we cloned luciferase constructs containing the HBV enhancer Ⅱ from variants and from HBV genotypes A and D and cotransfected them together with expression vectors for COUP-TF1 into HepG2 cells. RESULTS: Our fi ndings show that enhancer Ⅱ of HBV genotype A is also repressed by COUP-TF1. In contrast, two different enhancer Ⅱ constructs of HBV genotype D were activated by COUP-TF1. The activation was independent of the NRRE because a natural variant with a deletion of nt 1763-1770 was still activated by COUP- TF1. CONCLUSION: Regulation of transcription of the HBV genome seems to differ among HBV genomes derived from different genotypes. These differences in transcriptional control among HBV genotypes may be the molecular basis for differences in the clinical course among HBV genotypes.展开更多

We examined the incidence of concomitant injuries and their relevance with respect to hospitalization. Methods: Children aged between 0 - 18 years hospitalized for treatment of TBI (ICD 10;S06.0 - 9) during 2010-2011 were included. The data relating to concomitant injuries and the course of treatment were evaluated. Statistical analysis included multivariate regressions at a level of significance of p ≤ 0.05. Results: 794 children were treated for head injury in our hospital. Head injury with other associated injuries had been sustained by 158 (19.9%) children. The face and the extremities were the areas of the body most often affected (p = 0.001). Boys represent the majority within the cohort of multiple injured children (p = 0.0001). The older the child, the higher the percentage of children with concomitant injuries (r = 0.27;p = 0.034). There was a significant correlation between the severity of the head injury and the occurrence of concomitant injuries (r = 0.19;p = 0.046). Children with concomitant injuries were found to suffer significantly more falls (N = 82;51.9%) than road traffic accidents (N = 68;43%) (p = 0.0001). A comparison of different variables revealed that age (7 to 10 years), severity of head injury (mild TBI), and trauma mechanism (fall) were most influential (KB = ?1.55;p = 0.023) for concomitant injuries. Children with concomitant injuries have a significant longer stay in hospital than those without: mean stay 2.5 to 4.5 days (p = 0.0001). Conclusion: Concomitant injuries are hints for more severe head injuries and children should be examined with special care.展开更多

As shown in Case 1, double valve replacement in an infant with neonatal Marfan syndrome is feasible but its benefit on long term is uncertain. Excluding our patient, 3 infants with nMFS from the literature died early after cardiac surgery. Our second case is a unique patient who survives nMFS despite diaphragmatic herniae, dilated neonatal cisterna magna and severe atrioventricular valve insufficiencies. Treated with 0.7 mg/kg/day Carvedilol since his seventh month of life, he never developed severe heart failure. However despite his good health status at the age of 9 years, a progressive aortic root dilatation and left conornary aneurysm are still waiting for surgical repair.展开更多

Mothers of 68 children aged 8-17 years with juvenile idiopathic arthritis (JIA) or reactive arthritis reported behaviour problems (CBCL), children reported their actual stress level (SSK), functional disability in conducting activities of daily living (CHAQ) and health-related quality of life (HRQOL) including self-esteem (KINDL-R). Children and adolescents with JIA or reactive arthritis reported lower self-esteem compared to normative data. Almost 20%of the samples were reported to have serious behaviour problems,mostly social isolation and depression/anxiety. Children with lower HRQOL, more functional limitations and a higher stress level showed more behaviour problems. Self-esteem and behaviour problems may be relevant outcome measures in children and adolescents with chronic arthritis and useful to monitor psychosocial support in this population.展开更多
