PFOA and testis cancer in the Veneto Region (Italy).

The largest documented episode of human contamination by PFOA in the world (approximately 150,000 actual residents on 1 January 2020) has occurred in Italy's Veneto Region. In this large, mostly flat plain area, a cluster of testicular cancers has also been observed. Preliminary data are reported, and the most relevant and recent recommendations regarding the health surveillance of exposed individuals are emphasized.

Lactoferrin in the Prevention of Recurrent Respiratory Infections in Preschool Children: A Prospective Randomized Study.

Few studies have evaluated the effect of bovine lactoferrin (bLf) on reducing respiratory infections in preschool children. This randomized controlled trial evaluated the effect of bLf in preschool children with recurrent respiratory infections. Participants were randomly assigned bLf (n = 25) or control (n = 25). Outcomes included respiratory infection episodes (RIEs), symptom duration, school absence and medication. Fifty children aged 4.2 ± 0.1 years were included. During the active 4-month phase, median number of RIEs was reduced by 50% in the bLf group [1-episode, interquartile range (IQR): 0-2] vs. control (2, IQR: 1-3; p = 0.02). The proportion of participants with >3 RIEs was significantly lower in bLf (n = 1, 4%) vs. control (n = 7, 28%) with 80% lower odds of upper RIEs in the bLf arm (odds ratio: 0.20, 95% CI:0.06-0.74, p = 0.015). The duration of symptoms (3 vs. 6, p = 0.009) and days absent from school (3 vs. 6, p = 0.15) were lower in the active arm. Over the 2-month follow-up, no significant differences were observed between groups for infection episodes, symptom duration or school absence. However, bLf-treated children received significantly less corticosteroids over the entire 6-month study period (32% vs. 60%; p = 0.047). bLf supplementation significantly reduced the frequency and duration of RIEs in children with decreased corticosteroid use.

Prevention of recurrent respiratory infections : Inter-society Consensus.

Recurrent respiratory infections (RRIs) are a common clinical condition in children, in fact about 25% of children under 1 year and 6% of children during the first 6 years of life have RRIs. In most cases, infections occur with mild clinical manifestations and the frequency of episodes tends to decrease over time with a complete resolution by 12 years of age. However, RRIs significantly reduce child and family quality of life and lead to significant medical and social costs.Despite the importance of this condition, there is currently no agreed definition of the term RRIs in the literature, especially concerning the frequency and type of infectious episodes to be considered. The aim of this consensus document is to propose an updated definition and provide recommendations with the intent of guiding the physician in the complex process of diagnosis, management and prevention of RRIs.

Vaccine confidence among parents: Large scale study in eighteen European countries.

BACKGROUND: Despite the fact that vaccines save 2-3 million lives worldwide every year, a percentage of children are not getting appropriately vaccinated, thus leading to disease outbreaks. One of the major reasons of low vaccine uptake in Europe is vaccine hesitancy, contributing to the recent measles outbreaks. Monitoring of vaccine hesitancy is valuable in early identification of vaccine concerns. METHODS: We performed an eighteen country European survey on parents' attitudes and behaviors regarding their children's immunization. Parents having at least one child 1-4 years old were mostly recruited by primary care paediatricians to reply to a web-based questionnaire. The questionnaire was developed by the European Academy of Paediatrics Research in Ambulatory Setting Network steering committee, based on similar surveys. An individual level hesitancy score was constructed using the answers to 21 questions, and correlations of the score with socio-demographic characteristics and types of providers were explored. To assess inter country differences, a country level self -reported confidence was defined. RESULTS: Fifty six percent and 24% of 5736 respondents defined themselves as "not at all hesitant", and "somewhat hesitant", respectively. Parents who consulted general practitioners were more hesitant than parents who consulted pediatricians (p < 0.05). Consultation with homeopathists was associated with the highest reported hesitancy (p < 0.05). Vaccine confidence was highest in Portugal and Cyprus, and lowest in Bulgaria and Poland. CONCLUSION: The majority of parents in Europe believe in the importance of childhood vaccination. However, significant lack of confidence was found in certain European countries, highlighting the need for continuous monitoring, awareness and response plans. The possible influence of different types of healthcare providers on parental decisions demonstrated for the first time in our survey, calls for further research. Monitoring and continuous medical education efforts aimed mostly at those professionals who might not be likely to recommend vaccination are suggested.

Sleep habits and pattern in 1-14 years old children and relationship with video devices use and evening and night child activities.

BACKGROUND: Sleep in childhood and adolescence is crucial for mental and physical health; however several researches reported an increasing trend towards a sleep deprivation in this age. Due to the lack of recent epidemiological studies in Italy, the aim of our study was to depict sleep habits and patterns in Italian children aged 1-14 years and to evaluate their relationships with video devices use (TV, tablet, smartphone, PC) and evening/night child activities. METHODS: A structured interview was conducted during 2015 by 72 Family Pediatricians in 2030 healthy children aged 1-14 years by a cross-sectional survey named "Ci piace sognare". Total sleep duration was calculated, 2015 National Sleep Foundation Recommendations were used as reference. Optimal sleepers were defined children sleeping in own bed all night without awakenings. Multivariable median regression was performed to identify predictors of sleep duration and multivariable logistic regression for predictors of optimal sleep. RESULTS: Total sleep duration and numbers of awakenings decreased with age. Only 66.9% of children had sleep duration in agreement with Recommendations (50% in 10-14 years group). Before sleeping 63.5% of children used video devices (39.6% at 1-3 years), 39.1% read, 27.5% drank and 19.5% ate. Bottle users at bedtime were 30.8% at 1-3 years, 16.6% at 3-5 years and 4.9% at 5-7 years. Overall, 23.4% of children changed sleeping place during the night, 22.4% referred sleeping problems in the first year of life. Video devices use was negative predictor of sleep duration (-0.25 h [95%CI:-0.35,-0.14], p < 0.001). Optimal sleep was inversely related with bedroom TV (OR 0.63 [0.50,0.79], p < 0.001), with sleeping disorders in the first year (OR 0.62 [0.48,0.80], p < 0.001)), with bottle use (OR 0.64 [0.44,0.94], p < 0.05) and posivively related with high mother's education level (OR 1.44 [1.11,1.88], p < 0.01). CONCLUSIONS: About one third of 1 to 14 year Italian children sleep less than recommended, one half in teenage. Modifiable risk factors for sleep abnormalities such as video devices use, bedroom TV and bottle use should be target of preventive strategies for a correct sleep. Pediatricians should give priority to the identification of sleep disorders early in life.

Pneumococcal serotype distribution in adults with invasive disease and in carrier children in Italy: Should we expect herd protection of adults through infants' vaccination?

The 7-valent pneumococcal conjugate vaccine (PCV7) produced a significant herd protection in unvaccinated adult population mostly because of pneumococcus carriage decrease in vaccinated children. It is not known if the 13-valent pneumococcal vaccine can give similar effect on adults. Aims of the work were to evaluate whether the 6 additional serotypes are present in nasopharynx of children and serotype distribution in invasive pneumococcal infections (IPD) in adults. Realtime-PCR was used to evaluate pneumococcal serotypes in adults with confirmed IPD and in nasopharyngeal swabs (NP) from 629 children not vaccinated or vaccinated with PCV7 and resident in the same geographical areas. Two hundred twenty-one patients (116 males, median 67.9 years) with IPD were studied (pneumonia n = 103, meningitis n = 61 sepsis n = 50, other n = 7). Two hundred twelve were serotyped. The most frequent serotypes were 3, (31/212; 14.6%), 19A, (19/212; 9.0%), 12 (17/212; 8.0%), 7F, (14/212; 6.6%). In NP of children, the frequency of those serotypes causing over 50% of IPD in adults was very low, ranging from 0.48% for serotype 7F to 7.9% for serotype 19A. On the other side serotype 5, very frequent in NP (18.7%) caused <1% IPD. In conclusion serotypes causing IPD in adults are very rarely found in children NP. We suggest that herd protection obtainable with the additional 6 serotypes included in PCV13 may be more limited than that demonstrated with PCV7 in the past. In order to reduce the burden of disease in adults, adults should be offered a specific vaccination program with highly immunogenic PCV.

Pidotimod for the prevention of acute respiratory infections in healthy children entering into daycare: A double blind randomized placebo-controlled study.

Acute respiratory tract infections (ARTIs) are very common in pediatric age and reach a peak in the first 4 years of life, especially in children attending daycare. Pidotimod, a synthetic immunostimulant, may reduce the incidence of ARTIs in children with predisposing risk factors. Nevertheless studies on healthy children are presently lacking. We performed a double-blinded randomized placebo-controlled trial study to assess the efficacy of Pidotimod in a population of 3-year-old healthy children who just entered kindergarten. The main outcome was the incidence of respiratory infections in this population and the secondary outcome was the prescription of antibiotics. The study group consisted of healthy 3-year-old children who had not yet attended day-care centers. Patients were enrolled by a convenience sample of 17 family pediatricians (FP). Children were randomized to receive either Pidotimod 400 mg per os or placebo twice daily for the last 10 days of each month from October 2013 to April 2014. Any time a child presented to his/her FP with fever and ARTI was diagnosed, clinical and therapeutic data were collected. A total of 800 children were pre-screened, 733 did not meet the inclusion criteria and 10 refused to participate. Of the 67 eligible subjects, 57 were successfully enrolled within the study recruitment period and randomized to receive Pidotimod (n = 29) or placebo (n = 28). Eight children were lost to follow-up. In the final analysis were thus included 24 children who received Pidotimod and 25 who received placebo. The incidence rate ratio for respiratory infections was 0.78 (95%CI 0.53 to 1.15, p = 0.211) for Pidotimod vs. placebo. The corresponding risk ratio for antibiotic usage was 0.56 (95%CI 0.27 to 1.16, p = 0.120). In our trial, Pidotimod did not prove to be statistically superior to placebo for the prevention of ARTI in a population of healthy children who entered kindergarten. However, Pidotimod showed some potential as a means for reducing antibiotic usage in these children.

Italian survey on general pediatricians' approach to children with gastroesophageal reflux symptoms.

UNLABELLED: The aim of the present study was to investigate the current approach of Italian general pediatricians to children with gastroesophageal reflux (GER) symptoms, evaluating the implementation of the 2009 North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN)-European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines. One hundred randomly identified Italian general pediatricians were asked to complete a case report-structured questionnaire investigating their approach to infants, children, and adolescents with symptoms suggestive of GER. Only 2 % of them showed complete adherence to the guidelines. Thirty-nine percent of them diagnosed GER disease based on clinical symptoms, irrespective of the age of the child; 56 % prescribed proton pump inhibitors (PPIs) in infants with unexplained crying and/or distressed behavior and 38 % in infants with uncomplicated recurrent regurgitation and vomiting; 57 % prescribed PPIs in children younger than 8-12 years of age with vomiting and heartburn, without specific testing; and 54 % discontinued PPI therapy abruptly. The overall rate of pediatricians over-prescribing PPIs was 79 %. CONCLUSION: According to our findings, most Italian general pediatricians do not seem to follow the recommendations of the 2009 NASPGHAN-ESPGHAN reflux guidelines and often prescribe PPIs despite a lack of efficacy for the symptoms being treated. We are well aware that the guidelines address the average situation and that the evaluation of individual patients may frequently reveal reasons for opening criteria for exceptions. Nevertheless, the over-diagnosis of gastroesophageal reflux disease (GERD) places undue burden on both families and national health system which has not been impacted by the publication of international guidelines.

Nasal saline irrigation in preschool children: a survey of attitudes and prescribing habits of primary care pediatricians working in northern Italy.

BACKGROUND: It has been shown that nasal saline irrigation (NSI) alone can be effective in children with infectious and/or allergic respiratory problems, but no study has assessed the awareness or clinical use of NSI among practising pediatricians. The main aim of this study was to evaluate the use of NSI in pre-school children by primary care pediatricians working in northern Italy. METHODS: Nine hundred randomly selected National Health Service primary care pediatricians with an e-mail address were sent an e-mail asking whether they were willing to respond to a questionnaire regarding the use of NSI. The 870 who answered positively were sent an anonymous questionnaire by post and e-mail that had 17 multiple-choice items. RESULTS: Completed questionnaires were received from 860 of the 870 primary care pediatricians (98.8%). NSI was used by almost all the respondents (99.3%), although with significant differences in frequency. It was considered both a prophylactic and a therapeutic measure by most of the respondents (60.3%), who prescribed it every day for healthy children and more frequently when they were ill. Most of the primary care pediatricians (87%) indicated an isotonic solution as the preferred solution, and the most frequently recommended administration devices were a nasal spray (67.7%) and bulb syringe (20.6%). Most of the pediatricians (75.6%) convinced parents to use NSI by explaining it could have various beneficial effects, and two-thirds (527/854; 61.7%) thought that most of the parents agreed about the importance of NSI. Analysis of possible associations between NSI prescribing behaviour and the demographic data revealed an associations with age and gender, with pediatricians aged <50 years prescribing NSI more frequently than their older counterparts (p < 0.01), and females prescribing NSI more frequently than males (p < 0.01). CONCLUSIONS: In Northern Italy, most primary care pediatricians prescribe NSI for both the prophylaxis and therapy of upper respiratory tract problems in pre-school children. However, many aspects of the procedure are not clarified, and this reduces parental compliance. Given the medical and economic advantages of NSI, this situation should be changed as soon as possible.

Pneumococcal serotype distribution in 1315 nasopharyngeal swabs from a highly vaccinated cohort of Italian children as detected by RT-PCR.

The long term impact of 7-valent pneumococcal conjugate vaccine (PCV7) on pneumococcal colonization patterns remains unclear. Carriage and distribution of Streptococcus pneumoniae serotypes as detected by RT-PCR were evaluated in a cohort of 1315 children. S. pneumoniae was identified in the nasopharyngeal swab of 734 children (55.8%); 488/734 (66.5%) children carried more than 1 pneumococcal serotype. As a consequence of co-colonization, a total of 1,728 S. pneumoniae (belonging to 33 serotypes) were identified. As immunogenicity between 2 and 3 doses of PCV7 in the first year of life has been demonstrated to be similar, serotypes distribution was evaluated categorizing vaccination status as 0,1 and 2 or more doses in the first year of life. Among children who started vaccination in the first year of life, PCV7 serotypes were carried in 296 of 1,123 (29.5%) children who had received ≥2 PCV7 doses while were carried in 26 of 108 (26.8%) who had received no doses (p=not significant); only 17 children received 1 PCV7 and 3 of them were found positive for PCV7 serotypes. Among those who had received ≥2 doses of PCV7 in the first year of life, 47 of 192 (19.7%) carried a PCV7 serotype during the first year after last vaccination, 50 of 125 (28.6%) during the second year, 79 of 224 (35.3%) during the third year, and 65 of 143 (45.5%) during the fourth year (p 0.0001). We did not identify risk factors for PCV7 carriage among children that had received >2 vaccine doses. This study suggests that S. pneumoniae is present in the nasopharynx of the majority of children 0-5 years even if vaccinated, that PCV7 serotypes can be found in nasopharyngeal swabs of PCV7 vaccinated children and that the frequency of PCV7 serotypes increases with the increase of interval from vaccination.
