Inhaled corticosteroids in children with persistent asthma: dose-response effects on growth.
Inhaled corticosteroids (ICS) are the first-line treatment for children with persistent asthma. Their potential for growth suppression remains a matter of concern for parents and physicians. ⋯ We report an evidence-based ICS dose-dependent reduction in growth velocity in prepubescent school-aged children with mild to moderate persistent asthma. The choice of ICS molecule (mometasone, ciclesonide or fluticasone) was not found to affect the level of growth velocity response over a year. The effect of corticosteroids on growth was not consistently reported: among 22 eligible trials, only four comparisons reported the effects of corticosteroids on growth over one year. In view of parents' and clinicians' concerns, lack of or incomplete reporting of growth is a matter of concern given the importance of the topic. We recommend that growth be systematically reported in all trials involving children taking ICS for three months or longer. Until further data comparing low versus high ICS dose and trials of longer duration are available, we recommend that the minimal effective ICS dose be used in all children with asthma.

Meta Analysis Observational StudyA meta-epidemiological study to examine the association between bias and treatment effects in neonatal trials.
Randomized controlled trials are considered the gold standard for evidence on therapeutic interventions; however, they are susceptible to bias. The objectives of this observational study were to describe the methodological quality of neonatal randomized controlled trials and quantify the bias related to specific methodological and study-level characteristics. ⋯ This observational study of a sample of neonatal trials showed that most were at high risk of bias, indicating that there is room for improvement in the design, conduct and reporting of neonatal trials to ensure valid results for the most clinically important outcomes. We did not find an association between most risk of bias domains and effect estimates; however, we found that randomized controlled trials at high risk for selective outcome reporting were associated with overestimates of treatment benefits. These results need to be confirmed in larger samples.

Interventions for treating femoral shaft fractures in children and adolescents.
Fractures of the femoral shaft in children are relatively uncommon but serious injuries that disrupt the lives of children and their carers and can result in significant long-term disability. Treatment involves either surgical fixation, such as intramedullary nailing or external fixation, or conservative treatment involving prolonged immobilisation, often in hospital. ⋯ Different methods of treating fractures of the shaft of the thigh bone in children and adolescents Although uncommon, fractures of the femoral shaft (thigh bone) in children may require prolonged treatment in hospital and sometimes surgery. This can cause significant discomfort and can disrupt the lives of the children and their familles. This review compared different methods of treating these fractures. Surgical treatment comprises different methods of fixing the broken bones, such as internally-placed nails, or pins incorporated into an external frame (external fixation). Non-surgical or conservative treatment usually involves different types of plaster casts with or without traction (where a pulling force is applied to the leg). We searched for studies in the medical literature until August 2013. The review includes 10 randomised or quasi-randomised controlled trials that recruited 527 children. Four trials compared different surgical versus non-surgical treatments; three compared different methods of non-surgical treatment and three compared different methods of surgical treatment. Generally we are unsure about the results of these trials because some were at risk of bias, some results were contradictory and usually there was too little evidence to rule out chance findings. Most trials failed to report on self-assessed function or when children resumed their usual activities. Comparing surgical versus non-surgical treatment. Low quality evidence (one trial, 101 children) showed children had similar function at two years after having surgery, involving external fixation, compared with those treated with a plaster cast. The other three trials did not report this outcome. There was moderate quality evidence (four trials, 264 children, aged 4 to 12 years, followed up for 3 to 24 months) that surgery reduced the risk of malunion (the leg is deformed) compared with non-surgical treatment. However, low quality evidence (four trials) indicated that there were more serious adverse events such as infections after surgery. There was low quality evidence (one trial, 101 children) of similar satisfaction levels in children and parents with surgery involving external fixation and plaster cast only. However, there was low quality evidence (one trial, 46 children) that more parents were satisfied with surgery involving an internal nail than with traction followed by a cast and that surgery reduced the time taken off from school. Comparing various non-surgical treatments. Very low quality evidence means that we are very unsure if the rates of malunion differ or not between children treated with immediate plaster casts versus with traction followed by plaster cast (one trial, 42 children), or between children treated with traction followed by either a functional orthosis (a brace or cast that allows some movement) or a cast (one trial, 43 children). We are very unsure if either function or serious adverse events differ between young children (aged two to seven years) immobilised in single-leg versus double-leg casts (one trial, 52 children). However, single-leg casts appear to be easier to manage by parents and more comfortable for the child. Comparing various surgical treatments Very low quality evidence means that we are very unsure if the rates of malunion, serious adverse events, time to return to school or parental satisfaction actually differ in children whose fractures were fixed using internal nails or external fixation (one trial, 19 children).

Inhaled corticosteroids in children with persistent asthma: effects on growth.
Treatment guidelines for asthma recommend inhaled corticosteroids (ICS) as first-line therapy for children with persistent asthma. Although ICS treatment is generally considered safe in children, the potential systemic adverse effects related to regular use of these drugs have been and continue to be a matter of concern, especially the effects on linear growth. ⋯ Eleven of 25 trials did not report how they guaranteed that participants had an equal chance of receiving ICS or placebo or non-steroidal drugs. All but six trials did not report how researchers were kept unaware of the treatment assignment list. However, this methodological limitation may not significantly affect the quality of evidence because the results remained almost unchanged when we excluded these trials from the analysis.
