Aim: The number of primary care paediatricians is decreasing in Europe without a justifiable reason. We aimed to compare the clinical practice of paediatricians and family doctors attending children and adolescents in primary care., Methods: MEDLINE, Embase, CENTRAL, TRIP and Google Scholar were searched from December 2008 to February 2018. No language or study design restrictions were applied. Three reviewers assessed eligibility of the studies. Seven pairs of reviewers performed the data extraction and assessed the methodological quality independently. Discrepancies were resolved by consensus., Results: Fifty-four, out of 1150 studies preselected, were included. We found that paediatricians show more appropriate pharmacology prescription patterns for the illness being treated; they achieve higher vaccination rates and have better knowledge of vaccines and fewer doubts about vaccine safety; their knowledge and implementation of different screening tests are better; they prescribe psychoactive drugs more cautiously and more in line with current practice guidelines; their evaluation and treatment of obesity and lipid disorders follow criteria more consistently with current clinical practice guidelines; and they perform fewer diagnostic test, show a more suitable use of the test and request fewer referrals to specialists., Conclusion: According to published data, in developed countries, paediatricians provide higher quality care to children than family doctors., (© 2020 Foundation Acta Paediatrica.

Background: The undercarboxylated form of osteocalcin (ucOC) is an emerging marker of cardiovascular disease. It is unknown if ucOC in related to common cardiovascular risk markers in children. In offspring of families with and without metabolic syndrome (MetS+ and MetS- families), we assessed whether ucOC was related to a continuous metabolic syndrome score (MetS score) and to carotid intima-media thickness (cIMT)., Methods: ucOC and total OC, MetS score and cIMT were assessed in 203 asymptomatic prepubertal children (age 7.6 ± 0.1 yr; 49% girls), of whom 99 were from MetS+ families., Results: In children from MetS+ families, percent ucOC was higher than in children from MetS- families (p < 0.01). In offspring from MetS+ families, higher ucOC and especially higher percent ucOC was independently associated with both the MetS score and cIMT (both p ≤ 0.01)., Conclusions: The undercarboxylated form of OC is related to common cardiovascular risk markers in children at risk for cardiovascular disease., (Copyright © 2014 Elsevier Ireland Ltd.

Introduction: The objective of this systematic review is to determine if the treatment of streptococcal pharyngitis with a daily dose of amoxicillin is similar in effectiveness to other dosing schedules (every 6, 8 or 12 hours) of the same antibiotic or penicillin V., Material and Methods: Randomised clinical trials (RCT) comparing amoxicillin (one dose per day) compared to other dosages of amoxicillin (every 8-12 hours) or penicillin V (every 6, 8 or 12 hours). Search databases consulted: Medline, Central, EMBASE and Google Scholar. The results were combined using the risk difference (RD). We measured the effectiveness of each treatment with a negative throat culture on the 14-21th day, being previously positive to group A Streptococcus (under a non-inferiority hypothesis, where the upper limit of the 95% confidence interval [95% CI] of the DR does not exceed 10%) and clinical failure on days 10-21. The results were combined according to a fixed effects model or random depending on whether or not there was heterogeneity., Results: Four RCT met the selection criteria with 1,314 participants (657 received amoxicillin once per day, and 657 received other antibiotics or dosages): a) any positive culture for Streptococcus (14-21st day, 4 RCTs): DR: -0.5% (95% CI: -5.1% to 4.2%; b) persistence of the same serotype (14-21st day, 3 RCT): DR: 0.32% (95% CI: -3.1% to 3.7%; c) clinical failure (2 RCT): DR: 1.7% (95% CI: -1.9% to 5.4%; d) adverse effects (4 RCT): DR: -0.39% (95% CI: -1.5% to 6.8%). There were no statistically significant differences in any comparisons., Conclusions: Amoxicillin, administered once daily is not inferior to other dosages of the same antibiotic or penicillin V. These results are important because they may facilitate compliance., (Copyright © 2010 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.)

Introduction: The aim of this systematic review is to assess whether antibacterial agents are more effective than either placebo or no intervention at all in the treatment of acute bacterial sinusitis., Patients and Methods: We reviewed the databases and search engines: PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Google Scholar to identify randomized clinical trials (RCTs) in children comparing antibiotics versus placebo. Sinusitis was considered as the persistence of clinically compatible symptoms for at least 10 days. The methodological quality was assessed using the Jadad scale. Four RCTs were selected. We studied the following variables: cure, clinical improvement (on days 10 to 14), relapse-recurrence (from day 14 to day 60) and presence of adverse effects. The results were combined using meta-analysis. We used the fixed effects model or random model depending on whether or not there was heterogeneity. We estimated the combined relative risk (RR) and 95% confidence interval., Results: Only two RCTs had a Jadad scale score ≥3. Variable cure-improvement (4 RCTs): RR 1.11 (95% CI: 0.9 to 1.3). Variable relapse-recurrence (3 RCTs): RR 0.9 (95% CI: 0.6 to 1.5). Adverse effects (4 RCTs): 2.01 (95% CI 1.1 to 3.8)., Conclusions: In children with acute sinusitis, antibacterial agents at the studied doses did not appear to provide benefit in terms of cure and improvement, assessed at 10 to 14 days of follow up. Similarly, the percentage of relapse-recurrence was not lower among children who received antibiotics. Antibiotics are associated more frequently with adverse effects., (Copyright © 2010 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.)
