RESUMO
Despite great advances in describing Bordetella pertussis infection, the role of the host microbiota in pertussis pathogenesis remains unexplored. Indeed, the microbiota plays important role in defending against bacterial and viral respiratory infections. We investigated the nasopharyngeal microbiota in infants infected by B. pertussis (Bp), Rhinovirus (Rv) and simultaneously by both infectious agents (Bp + Rv). We demonstrated a specific nasopharyngeal microbiome profiles for Bp group, compared to Rv and Bp + Rv groups, and a reduction of microbial richness during coinfection compared to the single infections. The comparison amongst the three groups showed the increase of Alcaligenaceae and Achromobacter in Bp and Moraxellaceae and Moraxella in Rv group. Furthermore, correlation analysis between patients' features and nasopharyngeal microbiota profile highlighted a link between delivery and feeding modality, antibiotic administration and B. pertussis infection. A model classification demonstrated a microbiota fingerprinting specific of Bp and Rv infections. In conclusion, external factors since the first moments of life contribute to the alteration of nasopharyngeal microbiota, indeed increasing the susceptibility of the host to the pathogens' infections. When the infection is triggered, the presence of infectious agents modifies the microbiota favoring the overgrowth of commensal bacteria that turn in pathobionts, hence contributing to the disease severity.

BACKGROUND: Whether viral coinfections cause more severe disease than Bordetella pertussis (B. pertussis) alone remains unclear. We compared clinical disease severity and sought clinical and demographic differences between infants with B. pertussis infection alone and those with respiratory viral coinfections. We also analyzed how respiratory infections were distributed during the 2 years study. METHODS: We enrolled 53 infants with pertussis younger than 180 days (median age 58 days, range 17109 days, 64. 1% boys), hospitalized in the Pediatric Departments at "Sapienza" University Rome and Bambino Gesù Children's Hospital from August 2012 to November 2014. We tested in naso-pharyngeal washings B. pertussis and 14 respiratory viruses with real-time reverse-transcriptase-polymerase chain reaction. Clinical data were obtained from hospital records and demographic characteristics collected using a structured questionnaire. RESULTS: 28/53 infants had B. pertussis alone and 25 viral coinfection: 10 human rhinovirus (9 alone and 1 in coinfection with parainfluenza virus), 3 human coronavirus, 2 respiratory syncytial virus. No differences were observed in clinical disease severity between infants with B. pertussis infection alone and those with coinfections. Infants with B. pertussis alone were younger than infants with coinfections, and less often breastfeed at admission. CONCLUSIONS: In this descriptive study, no associations between clinical severity and pertussis with or without co-infections were found. TRIAL REGISTRATION: Policlinico Umberto I: protocol 213/14, 3085/13.02.2014, retrospectively registered. Bambino Gesù Children's Hospital: protocol n. RF-2010-2317709.

Background: We conducted a meta-analysis of articles published between January 2000 and July 2016 with the aim of defining the proportion of rubella seronegative women of childbearing age (WCBA), providing the best information available on the seroprevalence of rubella in this population. We selected articles published in the time period between 2000 and 2016. The pooled prevalence of rubella seronegative women was calculated by a fixed effect model and a random effect model, according to the heterogeneity among studies. Studies were sub-grouped by population type (pregnant women and WCBA with no mention of ongoing pregnancy) and by geographic area [World Health Organization (WHO) region]. Sensitivity analysis was performed to assess the stability of results. We found important differences in rubella seronegativity prevalence estimates by WHO Region. About 88% of the studies conducted on pregnant women reported a seronegativity rate >5%. The pooled rubella seronegativity prevalence was 9.3%. When considering population groups, we obtained a seronegativity pooled estimate of 9.4% for pregnant women and of 9.5% for WCBA with no mention of ongoing pregnancy. This meta-analysis shows that the proportion of WCBA who are susceptible to rubella is still high. The figures are worrisome, taking into account that the WHO set at 5% the rubella susceptibility threshold for WCBA.

BACKGROUND: Surgical Site Infections (SSIs) account for 16-34% of all health-care associated infections. This study aimed to assess the incidence rate of SSIs in children who underwent surgical procedures in an academic children's hospital in Italy. STUDY DESIGN: Prospective cohort study. METHODS: We actively followed-up 0-17 year old children at 30 days of surgical procedures without implants conducted during one index week per quarter, from the second quarter of 2014, to the first quarter of 2016 (8 index weeks in total). Follow up data were collected by telephone interview, or derived by clinical records if patients were still hospitalized. SSIs were defined according to case definitions of Centers for Diseases Control, Atlanta, USA. We calculated cumulative incidence of SSIs per 100 surgical procedures, by patient characteristics, procedure characteristics, and quarter. To investigate variables associated with SSIs, we compared characteristics of procedures with SSIs with those of procedures without SSIs. RESULTS: Over the study period, SSI incidence was 1.0% (19 cases/1,830 surgical procedures). SSI incidence was significantly lower after ear, nose and throat procedures compared to all other procedures, and significantly decreased over time. Duration of surgery was a risk factor for SSIs; patients with SSIs had a significantly longer total length of stay (LOS), due to a prolonged post-operative LOS. CONCLUSION: As reported in adults, this study confirms that SSIs are associated with longer hospitalizations in children. Active surveillance of SSIs is an important component of the overall strategy to reduce the incidence of these infections in children.

BACKGROUND: Among hospitalized adults and children pain is undertreated. This study wants to assess the effectiveness of pain therapy in two departments of a large children's hospital. MATERIALS AND METHODS: During a single day work three committees, administering a questionnaire to patients or parents, have evaluated the adherence to international recommendations (JCI and WHO) in the management of analgesic therapy. Patient demographics, prevalence and intensity (moderate and/or severe) of pain (during hospitalization, 24 hours before and at the time of the interview), analgesia (type, route, duration and frequency of administration) and Pain Management Index (=analgesic score-pain score) were recorded. RESULTS: 75 patients participated in the study (age: 2 months up to 24 years, mean 7.8 ± 6). During hospitalization 43 children (57%) had no pain while 32 (43%) have experienced pain. 22 children (29 %) had pain 24 hours before and 12 (16%) at the time of the interview. The average value of the PMI was -0.8±1.3 with a minimum of -3 and a maximum of +2: 60% (19) of the children had a PMI less than 0 (undertreated pain) while 40% (13) had a value=or>0. Out of 32 patients who needed an analgesic therapy 14 (44%) received an around-the-clock dosing, 8 (25%) an intermittent therapy and 10 (31%) no treatment.17 (77 %) were the single drug therapy and 5 (23%) the multimodal ones. CONCLUSIONS: The prevalence of pain in the two departments is high. The main cause is that knowledge is not still well translated into clinical practice.

PURPOSE: To evaluate the efficacy and tolerability of Perampanel (PER) in children and adolescents with refractory epilepsies in daily clinical practice conditions. PATIENTS AND METHODS: This Italian multicenter retrospective observational study was performed in 16 paediatric epilepsy centres. Inclusion criteria were: (i) ≤18 years of age, (ii) history of refractory epilepsy, (iii) a follow-up ≥5 months of PER add-on therapy. Exclusion criteria were: (i) a diagnosis of primary idiopathic generalized epilepsy, (ii) variation of concomitant AEDs during the previous 4 weeks. Response was defined as a ≥50% reduction in monthly seizure frequency compared with the baseline. RESULTS: 62 patients suffering from various refractory epilepsies were included in this study: 53% were males, the mean age was 14.2 years (range 6-18 years), 8 patients aged <12 years. Mean age at epilepsy onset was 3.4 years and the mean duration of epilepsy was 10.8 years (range 1-16), which ranged from 2 seizures per-month up to several seizures per-day (mean number=96.5). Symptomatic focal epilepsy was reported in 62.9% of cases. Mean number of AEDs used in the past was 7.1; mean number of concomitant AEDs was 2.48, with carbamazepine used in 43.5% of patients. Mean PER daily dose was 7.1mg (2-12mg). After an average of 6.6 months of follow-up (5-13 months), the retention rate was 77.4% (48/62). The response rate was 50%; 16% of patients achieved ≥75% seizure frequency reduction and 5% became completely seizure free. Seizure aggravation was observed in 9.7% of patients. Adverse events were reported in 19 patients (30.6%) and led to PER discontinuation in 4 patients (6.5%). The most common adverse events were behaviour disturbance (irritability and aggressiveness), dizziness, sedation and fatigue. CONCLUSION: PER was found to be a safe and effective treatment when used as adjunctive therapy in paediatric patients with uncontrolled epilepsy.

UNLABELLED: Controversy remains about the best line of division for liver splitting, through Segment IV or through the umbilical fissure. Both techniques are currently used, with the choice varying between surgical teams in the absence of an evidence-based choice. We conducted a single-center retrospective analysis of 47 left split liver grafts that were procured with two different division techniques: "classical" (N = 28, Group A) or through the umbilical fissure and plate (N = 19, Group B). The allocation of recipients to each group was at random; a single transplant team performed all transplantations. Demographics, characteristics, technical aspects, and outcomes were similar in both groups. The grafts in Group A, prepared with the classical technique, were procured more often with a single BD orifice compared with the grafts in Group B; however, this was not associated with a higher incidence of biliary problems in this series of transplants (96% actual graft survival rate [median ± s.d. FOLLOW-UP: 26 ± 20 months]). Both techniques provide good quality split grafts and an excellent outcome; surgical expertise with a given technique is more relevant than the technique itself. The classical technique, however, seems to be more flexible in various ways, and surgeons may find it to be preferable.

Biliary complications remain a major challenge for long-term success after LT, as it is, as a rule, the most common technical - early and late - complication that occurs, and because these complications contribute to a significant number of late graft losses and retransplantations. In the pediatric age group, both biliary atresia, as the patient's condition, and the use of a left liver graft, obtained by a liver division technique, make it necessary for the use of a Roux-en-Y jejunal loop for the biliary reconstruction in the majority of cases. A slight modification of the technique is presented, consisting of a straight positioning along the cut surface (rather than the conventional position that results in a harpoon shape). A favorable outcome in terms of a technical complication and graft survival was observed. This way of doing this is an interesting variation and adds to the surgical armamentarium.

OBJECTIVE: Acupuncture is known to reduce clinical pain, although the exact mechanism is unknown. The aim of the current study was to investigate the effect of acupuncture on laser-evoked potential amplitudes and laser pain perception. METHODS: In order to evaluate whether abdominal acupuncture is able to modify pain perception, 10 healthy subjects underwent a protocol in which laser-evoked potentials (LEPs) and laser pain perception were collected before the test (baseline), during abdominal acupuncture, and 15 min after needle removal. The same subjects also underwent a similar protocol in which, however, sham acupuncture without any needle penetration was used. RESULTS: During real acupuncture, both N1 and N2/P2 amplitudes were reduced, as compared to baseline (p<0.01). The reduction lasted up to 15 min after needle removal. Furthermore, laser pain perception was reduced during real acupuncture, although the difference was marginally significant (p=0.06). CONCLUSIONS: Our results show that abdominal acupuncture reduces LEP amplitude in healthy subjects. SIGNIFICANCE: Our results provide a theoretical background for the use of abdominal acupuncture as a therapeutic approach in the treatment of pain conditions. Future studies will have to be conducted in clinical painful syndromes, in order to confirm the analgesic effect of acupuncture in patients suffering from pain.

We reviewed the epidemiology of pertussis in Italy over the last 125 years to identify disease trends and factors that could have influenced these trends. We described mortality rates (1888-2012), case fatality rates (1925-2012), cumulative incidence rates (1925-2013) and age-specific incidence rates (1974-2013). We compared data from routine surveillance with data from a paediatric sentinel surveillance system to estimate under-notification. Pertussis mortality decreased from 42.5 per 100,000 population in 1890 to no reported pertussis-related death after 2002. Incidence decreased from 86.3 per 100,000 in 1927 to 1 per 100,000 after 2008. Vaccine coverage increased from 32.8% in 1993 to about 96% after 2006. As for under-notification, mean sentinel/routine surveillance incidence ratio increased with age (from 1.8 in <1 year-olds to 12.9 in 10-14 year-olds). Pertussis mortality decreased before the introduction of immunisation. Incidence has decreased only after the introduction of pertussis vaccine and in particular after the achievement of a high immunisation coverage with acellular vaccines. Routine surveillance does not show an increase in cumulative incidence nor in ≥ 15 year-olds as reported by other countries. Underrecognition because of atypical presentation and the infrequent use of laboratory tests may be responsible for under-notification, and therefore affect incidence reports and management of immunisation programmes.

Thanks to recent technological advances, measuring real-world interactions by the use of mobile devices and wearable sensors has become possible, allowing researchers to gather data on human social interactions in a variety of contexts with high spatial and temporal resolution. Empirical data describing contact networks have thus acquired a high level of detail that may yield new insights into the dynamics of infection transmission between individuals. At the same time, such data bring forth new challenges related to their statistical description and analysis, and to their use in mathematical models. In particular, the integration of highly detailed empirical data in computational frameworks designed to model the spread of infectious diseases raises the issue of assessing which representations of the raw data work best to inform the models. There is an emerging need to strike a balance between simplicity and detail in order to ensure both generalizability and accuracy of predictions. Here, we review recent work on the collection and analysis of highly detailed data on temporal networks of face-to-face human proximity, carried out in the context of the SocioPatterns collaboration. We discuss the various levels of coarse-graining that can be used to represent the data in order to inform models of infectious disease transmission. We also discuss several limitations of the data and future avenues for data collection and modelling efforts in the field of infectious diseases.

The objectives of this study were to determine the incidence of enteric pathogens causing acute gastroenteritis (AGE) among hospitalized children in a large Italian hospital, to measure the incidence of coinfections, and to compare the clinical characteristics of those infected with one versus multiple agents. A prospective study was conducted from March 2010 to April 2011 at the Bambino Gesù Pediatric Hospital in Rome, Italy. All patients between 1 month and 16 years of age admitted to the Pediatric Department with a diagnosis of AGE were eligible for enrollment. Two stool samples for each patient were tested for gastrointestinal pathogens. We summarized the clinical severity of episodes, describing the duration of diarrhea, duration and frequency of vomiting, fever, and severity of dehydration. All the patients underwent medical evaluation with estimation of dehydration. One or more etiological agents were detected in 151 out of 232 patients (65.1%), while we did not detect any etiological agent in 81 (34.9%). Rotavirus was detected in 96 (63.6%), adenovirus in 17 (11.2%), norovirus in 7 (4.6%), toxin-producing Clostridium difficile in 23 (15.2%), Salmonella spp. in 15 (9.9%, B group in 12/15 and D group in 3/15), C. perfringens in 12 (7.9%), Campylobacter spp. in 6 (4%), and verotoxigenic Escherichia coli (VTEC) in 2 (1.3%). In 27 children out of 151 (17.9%), we found evidence of coinfection. Coinfection with rotavirus and toxin-producing C. difficile was the most common (63%). Children with coinfection had a more severe clinical presentation and had a higher probability to be severely dehydrated, independently of age and living community type.

This study was conducted to evaluate the association between pneumococcal DNA load and parapneumonic pleural effusion (PPE) in children with community-acquired pneumonia. Bacterial load was quantified and related to the presence of PPE with or without empyema in 72 otherwise healthy children aged ≤5 years who were hospitalised because of radiographically confirmed CAP and showed a real-time polymerase chain reaction that was positive for Streptococcus pneumoniae. The proportion of children with a high bacterial load (i.e. ≥265 DNA copies/mL) was larger among the subjects with PPE than those without it. Multivariate analysis showed that a high bacterial load was significantly associated with PPE (OR 8.65; 95% CI 1.10-67.8 vs a bacterial load of <125 copies/mL). Children with infection due to pneumococcal serotype 19A were at highest risk of developing PPE (OR 7.44; 95% CI 1.10-50.4 vs all other typeable serotypes). The patients with CAP due to pneumococcal serotypes that are not included in the 13-valent conjugate vaccine (PCV13) were more frequently affected by PPE than those with infections associated with serotypes included in the vaccine, except for serotype 19A. Bacterial loads of ≥265 DNA copies/mL are significantly associated with PPE, and serotype 19A is significantly associated with a high bacterial load and the development of PPE. The mean bacterial load of the patients with empyema was higher than that of patients with simple PPE. Although further studies are required, it seems that serotypes not included in PCV13 can play a major role in causing a higher bacterial load and PPE.

Since children with chronic diseases represent a primary target for immunization strategies, it is important that their immunization coverage and timeliness of vaccines is optimal. We performed a study to measure immunization coverage and timeliness of vaccines in children with type 1 diabetes, HIV infection, Down syndrome, cystic fibrosis, and neurological diseases. A total of 275 children aged 6 months-18 years were included in the study. Coverage for diphtheria-tetanus-pertussis (DTP), polio (Pol), and hepatitis B (HBV) vaccines approximated 85% at 24 months, while measles-mumps-rubella (MMR) coverage was 62%. Immunization coverage for seasonal influenza was 59%. The analysis of timeliness revealed that there was heterogeneity among children with different chronic diseases. A proportional hazard model showed that children with HIV infection had the longest time to complete three doses of DTP, Pol, and HBV, and those with neurological diseases received the first dose of MMR later than the other categories. Causes of missing or delayed vaccination mostly included a concurrent acute disease. Children with chronic diseases should be strictly monitored for routine and recommended vaccinations, and health care providers and families should be properly informed to avoid false contraindications.

BACKGROUND: The food challenge test (FCT) is the gold standard for the diagnosis of food allergy. This procedure is time consuming, costly and can induce potentially severe symptoms. An ideal in vitro test should allow to avoid the FCT. Objective To assess the clinical performance of microarray for specific IgE (sIgE) detection in children with challenge-proven/excluded cow's milk (CM) or hen's egg (HE) allergy. METHODS: One-hundred and four children with suspected IgE-mediated hypersensitivity to CM or HE were studied. In all patients, skin prick test, ImmunoCAP, microarray and FCT were performed. RESULTS: The microarray components Bos d 8 for CM (27/58 patients) and Gal d 1 (20/46 patients) and Gal d 2 (24/46) for HE were the most frequently recognized allergens. Using the FCT results as the reference parameter, sIgE to Bos d 8 and Gal d 1 had the highest area under the curves. These were not significantly different from those obtained using the ImmunoCAP. Use of 95% clinical decision points (CDP) for sIgE to Bos d 8 and Gal d 1 resulted in higher negative predictive values (78% and 79%, respectively) than those obtained with the ImmunoCAP (57% and 59%). CONCLUSIONS: Our results show that in children with suspected CM or HE allergy, the microarray has a good ability to predict the FCT results. In a clinical application perspective, the microarray could be used as a second-level assay, if the ImmunoCAP sIgE is <95% CDP. This approach would lead to a decrease in the number of the FCT to be performed, as well as of positive FCTs with a subsequent decrease in severe reaction risk.

AIMS: We studied the effect of Telehomecare (THC) in a group of Cystic Fibrosis (CF) patients, with the aim to early recognize the relapses of pulmonary infections. Data obtained with Vivisol (OXYTEL) instrumentation were collected from 2001 to 2005. MATERIALS AND METHODS: The study has involved 17 patients (11 f, 6 m) affected by CF, treated with THC, in addition to the usual therapeutic protocol, for an average period of 29.6 months +/- 13.5. The mean age for THC enrollment was 15.74 years +/- 5.8. As controls, the study has involved the same patients during the 12 months prior to THC start-up and 28 patients affected by CF treated at our Unit (13 f, 15 m; average age 14.77 +/- 5.22). RESULTS: The results show a statistically significant decrease of outpatient accesses and increase of therapy cycles, and a trend of higher stability of the respiratory function, in THC treated subjects compared to controls. CONCLUSIONS: Our study suggests that THC programs may not be optimally accepted by CF patients, and that its use seems to increase in general the rate of access to health care without demonstrating any clear effect of pulmonary function.

A survey aimed to describe the prevalence of antibiotic use in hospitalised children was conducted in June 2007, in Bambino Gesù Children's Hospital in Rome which has the highest annual number of inpatients among paediatric hospitals in Italy. Data were collected by reviewing medical charts of all patients hospitalised for >48 hours. A total of 412 hospitalised children were evaluated; their median age was 42.3 months, and 55.6% were males. Antibiotics were prescribed to 181 of the 412 patients (43.9%). The prevalence was lowest (37.7%) in medical wards, higher (51.1%) in intensive care units and highest (52.2%) in surgical wards. Of the patients treated with antibiotics in surgical wards, 71% received the treatment as prophylaxis. The most frequently prescribed antibiotics were ceftazidime and the combination of amoxicillin and clavulanic acid. The observed prevalence of antibiotic use was within the range recently reported from other paediatric hospitals in Europe; however, it is advisable to collect data from all over the country in order to identify priority areas and design interventions. These results also highlight the need to implement guidelines for surgical prophylaxis in children, and to further investigate reasons for prescription of parenteral antibiotic therapy in paediatric hospitals.

OBJECTIVE: Pulmonary atresia with intact ventricular septum (PAIVS) is a rare cardiac malformation with a broad spectrum of anatomical manifestations, varying from types suitable for biventricular repair to those with diminutive right ventricle and primitive ventriculocoronary connections (VCC), more suitable for single-ventricle palliation or heart transplantation. We sought to test whether tricuspid regurgitation is an easily detectable prenatal criterion with which to identify PAIVS patients at lower risk of needing postnatal single-ventricle palliation. METHOD: We identified retrospectively patients with both fetal diagnosis and postnatal confirmation of PAIVS who were seen at Bambino Gesù Hospital between January 2000 and December 2006. Tricuspid valve/mitral valve (TV/MV) ratio, presence and severity of tricuspid regurgitation and direct visualization of VCC were evaluated by echocardiography both pre- and postnatally. RESULTS: We identified 22 patients with a prenatal diagnosis of PAIVS. Four pregnancies were terminated and one fetus was lost to follow-up, leaving 17 patients for the analysis. Based on postnatal cardiac catheterization and/or echocardiography we divided our population in two groups: Group 1 included 10 patients with VCC; Group 2 included seven patients without VCC. At fetal echocardiography, tricuspid regurgitation was absent in all ten Group 1 patients and present in all seven Group 2 patients. VCC were seen directly in 6/10 Group 1 patients and in no Group 2 patients. A cut-off value of 0.56 for the TV/MV ratio was highly predictive of VCC during fetal life, with a sensitivity of 100% and a specificity of 90%. CONCLUSIONS: The absence of tricuspid regurgitation in fetuses affected by PAIVS is a strong prenatal echocardiographic predictor of VCC, as is a TV/MV ratio < 0.56. Fetuses presenting with tricuspid regurgitation and relatively large right ventricle are at lower risk of needing single-ventricle palliation postnatally. This inforation could be helpful for appropriate prenatal counseling and postnatal decision-making.
