The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase.Electronic supplementary materialThe online version of this article (10.1186/s13052-018-0525-6) contains supplementary material, which is available to authorized users.

Purpose The aim of the present study was to translate, cross‐culturally adapt, and assess the psychometric properties of the Pedi‐IKDC and Pedi‐FABS scores in the Italian paediatric population with various knee pathologies. Methods In accordance with the Paediatric Anterior Cruciate Ligament Monitoring Initiative (PAMI) research protocol, the original English versions of the questionnaires were translated into Italian. All patients aged 8–16 and scheduled for knee surgery were considered eligible in the study. An open‐source platform was implemented to collect responses to the surveys which included general patient information, the questionnaires Pedi‐IKDC, and Pedi‐FABS. Two surveys were sent under stable clinical conditions before surgery (Q1 and Q2); a third survey was sent 3–4 months after surgery (Q3). The following properties were calculated: reliability, internal consistency, criterion validity, responsiveness, and floor/ceiling effects. Results Eighty‐nine patients completed Q1, 81 patients completed Q2, and 49 patients completed Q3. Both questionnaires demonstrated acceptable properties. Pedi‐IKDC: standard error of measurement (SEM) = 4.4, smallest detectable change (SDC) = 12.3, interclass correlation coefficient (ICC) = 0.96, Cronbach alpha (α) = 0.92, moderate‐to‐low correlation to Pedi‐FABS, effect size (ES) = 0.79, standardized response mean (SRM) = 0.86, floor = 0%, ceiling = 22%. Pedi‐FABS: SEM = 2.1, SDC = 5.8, ICC = 0.94, Cronback alpha (α) = 0.93, moderate‐to‐low correlation to Pedi‐IKDK, ES = 0.60, SRM = 0.51, floor = 19%, ceiling = 0%. Conclusions The Italian version of Pedi‐IKDC and Pedi‐FABS is valuable tools for patient assessment, by demonstrating good psychometric properties. In clinical setting, these questionnaires can be used to properly evaluate outcomes in Italian pediatric patients with knee pathologies. Level of evidence II.

A quite accurate prediction of the number of casts and the need for tenotomy can be performed in most cases. The Dimeglio score showed slightly better accuracy in predicting both steps of Ponseti treatment.

Using Pirani score in guiding indication for tenotomy may imply different decisions in a portion of cases, which should be considered when comparing series.

The treatment of a missed Monteggia (MM) fracture dislocation is still controversial. We describe our initial experience with ulnar osteotomy and progressive correction with unilateral external fixator in MM. We retrospectively evaluated 20 children undergoing ulnar osteotomy and progressive distraction angulation by unilateral external fixator to treat MM. Nine patients had closed reduction, whereas 11 patients had simultaneous open reduction, repair, or reconstruction of the annular ligament and K-wire stabilization of the radiocapitellar joint. Patients were followed for an average of 3 (1–11) years. Three children developed aseptic nonunion and one child had delayed union. A distal level of the osteotomy significantly increased the rate of nonunion or delayed union. At the final follow-up, eight children had complete reduction of the radial head, six children had partial reduction, whereas in six cases, the radial head remained dislocated. The angulation and the level of the osteotomy significantly influenced the relocation, whereas the open reduction had no significant effect on the final position of the radial head. At the final follow-up, the Kim’s score averaged 93.25. The flexion-extension arc significantly improved postoperatively, and it was positively correlated with the angulation. The ulnar osteotomy and progressive traction-angulation by unilateral external fixator can achieve satisfactory results in MM, if a meticulous surgical technique is applied; care must be taken regarding the level of osteotomy and the progressive traction-angulation.

This paper presents the application of a low-cost 3D printing technology in pre-operative planning and intra-operative decision-making. Starting from Computed Tomography (CT) scans, we were able to reconstruct a 3D model of the area of interest with a very simple and rapid workflow, using open-source software and an entry level 3D printer. The use of High Temperature Poly-Lactic Acid (HTPLA) by ProtoPasta allowed fabricating sterilizable models, which could be used within the surgical field. We believe that our method is an appealing alternative to high-end commercial products, being superior for cost and speed of production. It could be advantageous especially for small and less affluent hospitals that could produce customized sterilizable tools with little investment and high versatility.
