ReviewSystematic reviews, overviews of reviews and comparative effectiveness reviews: a discussion of approaches to knowledge synthesis.
The Cochrane Collaboration has been at the forefront of developing methods for knowledge synthesis internationally. ⋯ Systematic reviews bring together evidence from multiple studies in a rigorous fashion for a single intervention or group of interventions. Systematic reviews, as they have developed within healthcare, often focus on single or select interventions and direct pairwise comparisons; therefore, end-users may need to read several individual SRs to inform decision making. Overviews of reviews compile information from multiple SRs relevant to a single health problem. Overviews provide the end-user with a quick overview of the available evidence; however, overviews are dependent on the methods and decisions employed at the SR level. Furthermore, overviews do not often integrate evidence from different SRs quantitatively. Comparative effectiveness reviews, as we define them here, synthesize relevant evidence from individual studies to describe the relative benefits (or harms) of a range of interventions. Comparative effectiveness reviews may use statistical methods (network meta-analysis) to incorporate direct and indirect evidence; therefore, they can provide stronger inferences about the relative effectiveness (or safety) of interventions. While potentially more expensive and time-consuming to produce, a comparative effectiveness review provides a synthesis of a range of interventions for a given condition and the relative efficacy across interventions using consistent and standardized methodology.

ReviewTreatment of acute gastroenteritis in children: an overview of systematic reviews of interventions commonly used in developed countries.
Acute gastroenteritis (AGE) is an extremely common paediatric condition, which results in significant morbidity in children and is a financial burden to the society. ⋯ Given that oral rehydration is less invasive than IV rehydration with no evidence of important clinical differences, it is the first choice for rehydration in children with AGE and mild-to-moderate dehydration. As the vast majority of children with AGE do not require IV rehydration, oral ondansetron administration to children with significant vomiting should be performed to reduce the use of IV rehydration and the need for hospital admission. In children deemed too unwell to receive oral rehydration therapy, IV ondansetron administration is an option, as its use is associated with lower hospital admission rates. Although probiotics appear to be an effective option for the treatment of AGE amongst hospitalized children, outpatient data is lacking and more studies are urgently needed to determine the optimal organism, dosing and duration of treatment.

Review Meta AnalysisInterventions for promoting reintegration and reducing harmful behaviour and lifestyles in street-connected children and young people.
Numbers of street-connected children and young people run into many millions worldwide and include children and young people who live or work in street environments. Whether or not they remain connected to their families of origin, and despite many strengths and resiliencies, they are vulnerable to a range of risks and are excluded from mainstream social structures and opportunities. ⋯ Analysis across the included studies found no consistently significant benefit for the 'new' interventions compared to standard services for street-connected children and young people. These latter interventions, however, have not been rigorously evaluated, especially in the context of LMICs. Robustly evaluating the interventions would enable better recommendations to be made for service delivery. There is a need for future research in LMICs that includes children who are on the streets due to urbanisation, war or migration and who may be vulnerable to risks such as trafficking.

Anaphylaxis is a serious hypersensitivity reaction that is rapid in onset and may result in death. Anaphylaxis guidelines recommend glucocorticoids for the treatment of people experiencing anaphylaxis. ⋯ We are, based on this review, unable to make any recommendations for the use of glucocorticoids in the treatment of anaphylaxis.

ReviewProphylactic drug management for febrile seizures in children (Review).
Febrile seizures occurring in a child older than one month during an episode of fever affect 2% to 4% of children in Great Britain and the United States and recur in 30%. Rapid-acting antiepileptics and antipyretics given during subsequent fever episodes have been used to avoid the adverse effects of continuous antiepileptic drugs. ⋯ No clinically important benefits for children with febrile seizures were found for intermittent oral diazepam, phenytoin, phenobarbitone, intermittent rectal diazepam, valproate, pyridoxine, intermittent phenobarbitone or intermittent ibuprofen, nor for diclofenac versus placebo followed by ibuprofen, acetominophen or placebo. Adverse effects were reported in up to 30% of children. Apparent benefit for clobazam treatment in one recent trial needs to be replicated to be judged reliable. Given the benign nature of recurrent febrile seizures, and the high prevalence of adverse effects of these drugs, parents and families should be supported with adequate contact details of medical services and information on recurrence, first aid management and, most importantly, the benign nature of the phenomenon.
