Background: Previous trials, performed in subjects affected by recurrent streptococcal pharyngo-tonsillar infection, have shown that the use for 90 days of Streptococcus salivarius K12 (K12), an oral colonizing probiotic producing lantibiotic bacteriocins, reduces the occurrence of streptococcal and viral pharyngitis and acute otitis media (AOM). The aim was to evaluate the role of K12 in reducing the incidence of streptococcal and viral pharyngo-tonsillitis and AOM when administered in two separate trimesters, from October to December and then from April to June, in pediatric subjects with non-recurrent streptococcal infection., Methods: We retrospectively analyzed the incidence of pharyngo-tonsillitis and AOM in 133 children by comparing the number of episodes occurring between September 1st, 2014 and August 31st, 2015, when no treatment with K12 was given, with the period between September 1st, 2015 and August 31st, 2016, when K12 was administered., Results: Analysis of the findings for the 133 children demonstrated that K12 use decreased the incidence of pharyngo-tonsillitis by about 90% (P<0.001) and the occurrence of AOM by about 70% (P<0.001) and confirms the high safety profile of the strain., Conclusions: As already demonstrated in subjects with recurrent streptococcal pharyngo-tonsillar infection, K12, if administered for two trimesters out of 12 months, is associated with a reduced incidence of pharyngitis and AOM in pediatric subjects with non-recurrent streptococcal infection.

Background: Sport is very important for health promotion and conservation. Active lifestyle and regular exercise reduce cardiovascular disease incidence. The Italian Ministry of Health issued the Law Decree no. 243 (10/18/2014) concerning "guidelines for certification about non-competitive sports" to promote safety in sports. This regulation defines the activities for which a certificate is required, the professional actors involved and the clinical exams to be performed according to the patient's health status. In particular, the Law Decree recommends to perform an electrocardiogram (ECG) "at least once in a lifetime", introducing much greater news into pediatric practice., Methods: We proposed a survey evaluating frequency of ECG implementation for non-competitive sports and cardiovascular diseases incidence was administered to 7 Ligurian pediatricians., Results: The number of ECG/year for pediatrician increased from 10 ECG/year to 50 ECG/year with an indication of suitability to non-competitive sports. One case of QT prolongation and 2 cases of type 1 Brugada ECG pattern were diagnosed. In addition, 3 patients had an atrial septal defect and 3 children had a ventricular septal defect. Forty-three percent of the pediatricians considered useful performing the ECG., Conclusions: ECG in children has enhanced the positive effects on the community health. However, it remains to be defined in agreement with scientific societies the age at which to perform ECG, the sports for which ECG is required and the cost-benefit ratio for the National Health System and families.

Background: The PedsQL™3.0 Diabetes Module is a widely used instrument to measure the disease-specific health-related quality of life summary measures in children and adolescents with type 1 diabetes. After cultural adaptation, we confirmed reliability and validity of PedsQL™3.0 Diabetes Module in its Italian version., Methods: Participants were 169 Italian children and adolescents with type 1 diabetes aged 5-18 years and 100 parents. Reliability was determined by internal consistency using Cronbach's coefficient alpha, and test-retest reliability by intra-class correlation coefficient (ICC). Validity was assessed through factor validity examined by exploratory factor analysis, and discriminant validity examined through multitrait/multi-item scaling analysis. Discriminant validity with respect to dichotomous patients' characteristics at baseline was also examined through a multivariate analysis on the summary measures using the Wilks' Lambda test., Results: Data completeness was optimal. Item internal consistency was satisfied at 89% for the child self-report scales and at 100% for the parents' proxy-report scales. Most diabetes module scales was acceptable for group comparisons. Discriminant validity was satisfied for 71% of children and adolescents and for 82% of parents. A ≥70% Cronbach's α coefficient was found for the summary measures of both reports. For the test-retest reliability, the ICC coefficients ranged from 0.66 (i.e., the Worry scale) to 0.82 for the other scales of the child self-report. The ICC coefficients were ≥0.87 for all the parents' proxy-report scales. Factor analysis showed that the PedsQL™3.0 Diabetes Module for child self-report could be summarized in 10 components, which explained the 62% of the variance. For the parent proxy-report the statistical analysis selected 9 factors, which explained about 68% of variance. The external discriminant validity of the PedsQL™3.0 Diabetes Module summary measures were compared across gender, age, time since diagnosis and HbA1c mean cut off values. Significant differences in the "Treatment adherence" scale and in the "Communication" scale were observed across age, and by time since diagnosis., Conclusions: The results show the reliability and validity of the Italian translation of the PedsQL™3.0 Diabetes Module, supporting therefore its use as an outcome measure for diabetes cross-national clinical trials and research.
