Although NOSE score approximately allow to quantify nasal obstruction, in children, especially between 6 and 9 years of age, an objective measurement of nasal patency should be performed to better define the therapeutic approach.

BackgroundAllergy represents a risk factor at the base of sleep-disordered breathing in pediatric age. Among allergic diseases, the atopy is characterized by a tendency to be “hyperallergic.” Sleep-disordered breathing is also known in orthodontics as correlated with the morphology of craniofacial complex. The aim of this study was to investigate the relation between atopy and sleep-disordered breathing (oral breathers with habitual snoring), comparing atopic children with sleep-disordered breathing (test group) with nonatopic ones with sleep-disordered breathing (control group), in the prevalence of dento-skeletal alterations and other risk factors that trigger sleep-disordered breathing, such as adenotonsillar hypertrophy, turbinate hypertrophy, obesity, and alteration of oxygen arterial saturation.MethodsIn a group of 110 subjects with sleep-disordered breathing (6 to 12 years old), we grouped the subjects into atopic (test group, 60 subjects) and nonatopic (control group, 50 subjects) children and compared the data on the following: skin allergic tests, rhinoscopy, rhinomanometry, night home pulsoxymetry, body mass index, and dento-facial alterations.ResultsEven if our results suggest that atopy is not a direct risk factor for sleep-disordered breathing, the importance of a physiologic nasal respiration in the pathogenesis of sleep-disordered breathing seems to be demonstrated in our study by the higher prevalence of hypertrophy in the adenotonsillar lymphatic tissue, odontostomatological alterations, alterations of the oxygen saturation to pulsoxymetry, and higher prevalence of obesity observed in our children with sleep-disordered breathing, in percentages higher than that of the general pediatric population previously observed in the literature.ConclusionsThe importance of a physiologic nasal respiration in the pathogenesis of sleep-disordered breathing is demonstrated in our study.

Purpose of review There is growing evidence encouraging the use of probiotics in many conditions in children. However, given the wide number of probiotics available and contradictory data in the literature, the health-care provider is often faced with uncertainness about whether or not to use probiotics and which one(s) to choose. We here review current hypotheses regarding the efficacy and safety of probiotics and evaluate the available data on the use of probiotics in most common diseases in children. Considering that probiotics have strain-specific effects, we will focus on individual probiotic strains rather than on probiotics in general. Recent findings Strain-specific efficacy was clearly demonstrated with Lactobacillus rhamnosus GG and Saccharomyces boulardii I-745 in the treatment of acute infectious diarrhea, Lactobacillus reuteri DSM 17938 in infantile colics, Lactobacillus rhamnosus GG, and VSL#3 in irritable bowel syndrome. In addition, encouraging results are seen for use of probiotics in necrotizing enterocolitis, food allergy, and nonalcoholic fatty liver disease. However, the data available for constipation are to be considered somewhat equivocal. Summary The clinical relevance of these findings indicates that healthcare providers need to take strain-specificity and disease specificity of probiotics into consideration when recommending probiotic for their patients.

Background: No consensus has ever been reached about the correlation between nasal resistance and the subjective sensation of nasal patency. The aim of the present study was to better de ne whether primary school and secondary school aged children correctly estimate their nasal obstruction. Materials and methods: Two hundred eighty four children (168 males and 116 female) aged between 6 and 14 years (9.5+2.9 years) affected by Pediatric Allergic Rhinitis underwent Rhinomanometry and they were considered as correctly estimating their nasal obstruction when the grade of nasal patency corresponded to the severity of the NOSE score, overestimating when the grade of nasal patency was <1 when compared to the severity of the score, underestimating when the grade of nasal patency was >1 when compared to the severity of the score. Results: Correlation between NOSE score and nasal patency was statistically significant (r -0.74; p<0.001). Children between 6 and 9 years of age underestimate (43.7%) and children >12 overestimate (34.7%) their symptoms more frequently than children among other age ranges (p<0.001). Conclusion: Although NOSE score approximately allow to quantify nasal obstruction, in children, especially between 6 and 9 years of age, an objective measurement of nasal patency should be performed to better define the therapeutic approach.
