Abstract
Abstract
Background
Controlling inappropriateness of care, a widespread phenomenon, should be a global target in order to improve the quality of care, save money and ensure system sustainability. Inappropriateness is a relevant issue in public health and in rehabilitation medicine specifically. In fact, admitting a patient to a rehabilitation hospital or unit is a complex decision also due to the absence of shared and objective admission criteria. Aim of this study is to define clinical admission criteria and rules in rehabilitation medicine.
Methods
A three-round Delphi survey was conducted on a sample of rehabilitation medicine experts skilled in both rehabilitation and healthcare organization. The two initial rounds consisted of an electronic online questionnaire concerning appropriateness of admission to intensive rehabilitation while in the third one a report of the results was provided to the participants. The experts had to score their agreement with each item in the questionnaires, based on either a Likert scale or a dichotomous statement. Consensus between the experts was assessed.
Results
A total of 53 health professionals completed the Delphi survey. 19 out of 20 Italian regions were represented. The first round consisted of 8 multiple-choice questions questionnaire. The second round was designed thanks to the suggestions provided by the panelists in the previous one and consisted of a twelve items questionnaire. At the end of the survey, eight criteria of appropriateness of admission to rehabilitation were identified and five rules defining an appropriate admission to a rehabilitation facility were elaborated.
Conclusions
This study represents an attempt to create a worthwhile and reliable tool for a more conscious clinical practice in admission to rehabilitation, based on a set of shared criteria and rules.
Key messages
Improving appropriateness in healthcare delivery must be a primary goal in public health and in rehabilitation medicine specifically. Delphi method was applied to define shared clinical admission criteria and rules in rehabilitation.

Abstract
Abstract
Background
Falls and fall-related injuries are a major public health issue which needs global attention due to its clinical and socioeconomic impact. Inpatient falls are the most common adverse event in hospital. Important risk factors for falls are polypharmacy and the assumption of so-called Fall Risk Increasing Drugs (FRIDs). Aims of our study were to investigate the associations between falls and the use of medications among inpatients by conducting a retrospective case-control study in a rehabilitation hospital in Northern Italy in 2018.
Methods
Three unique control for each faller, matched by age, sex and hospitalization ward, were selected. A Conditional Logistic Regression was performed to analyze the impact that 13 types of FRIDs individually and the number of administrated FRIDs had on the risk of falling. A second regression model was obtained adjusting the case-control matching for CIRS, Morse and Barthel scores.
Results
We identified 148 cases and 444 controls. 3 types of FRIDs were significantly correlated (p < 0,05) with an increased risk of falling: Antipsychotics [OR:1,98;CI 95%:1,01-3,89], Antidepressants [OR:2,18;CI 95%:1,32-3,59], Diuretics [OR:1,71;CI 95%:1,09-2,68]. Antidepressants were the only type of FRID significantly correlated (p = 0,008) even in the model adjusted for CIRS, Morse and Barthel scores [OR:2,00;CI 95%:1,20-3,34]. The unadjusted model showed that the addition of one type of FRID to therapy was significantly associated with the fall event (p < 0.05) [OR:1.21;CI 95%: 1.05 - 1.40].
Conclusions
Assumption of drugs and polypharmacy could play a role in hospital falling. Recently developed fall risk assessment tools suffer from low specificity and sensitivity and do not assess these risk factors. A holistic approach with a multidimensional evaluation of the patient through screening tools, functional assessment tools and a full medical evaluation should be improved.
Key messages
Drugs may represent an important variable in determining the risk of falls in hospitalized patients, but they should not be considered alone. Screening tools for fall risk should take into account polypharmacy such as other intrinsic and extrinsic risk factors within an holistic approach.

Abstract
Abstract
Background
Adequate vaccination coverage among healthcare workers, including students in healthcare professions (SHPs), is crucial in order to prevent spreading of infections within healthcare facilities. However, vaccination coverage among SHPs is often inadequate. We aimed to describe the vaccination/immunization status of SHPs of the University of Milan.
Methods
We spread an e-survey to the academic e-mail addresses of postgraduate medical residents and to first- and last-year undergraduate SHPs. The questionnaire covered sociodemographic data (age, sex, education, municipality of residence, internship in high-risk wards) and the reported vaccination/immunization status for Influenza (previous flu season), Varicella, MPR and DTaP vaccines.
Results
Among 5743 invited SHPs, 884 participated in the survey. The study sample comprised 462 medical residents and 422 undergraduate SHPs (medicine 176, nursery 186, midwifery 4, healthcare assistance 32, prevention techniques 24). Median age was 27 years (IQR 7); 68.4% participants were female; 91.3% had attended high school in a lyceum, while others in a professional (2.9%) or technical (5.8%) institute; 36.7% lived in municipalities of < 20.000 inhabitants, while 26.1% of > 250.000. Traineeships took place in high-risk wards for 46% of participants. Reported vaccination coverage for Influenza was 33,7% (with higher coverage for pediatric nursing and midwifery students, medicine students and medical residents). Participants reported immunity (either vaccine or natural immunity) to Varicella in 93,3% cases. Declared vaccination coverage for Hepatitis B was 94,1%; 91,7% participants reportedly completed the MPR schedule, 76,2% the recommended DTaP booster.
Conclusions
Influenza vaccination coverage was suboptimal in our sample of SHPs, suggesting the need of specific educational programs and targeted vaccination campaigns, which may help shaping a positive vaccination attitude for future healthcare professionals.
Key messages
Immunization status for VPDs is suboptimal among Italian students in healthcare professions. The monitoring of the immunization status should include healthcare students actively involved in healthcare activities.

Abstract
Knowledge of whether and how respiratory microbiota composition can prime the immune system and provide colonisation resistance, limiting consecutive pathobiont overgrowth and infections, is essential to improving the prevention and therapy of respiratory disorders. Modulation of dysbiotic ecosystems or reconstitution of missing microbes might be a possible measure to reduce respiratory diseases. The aim of this review is to analyse the role of nasopharyngeal microbiota in the development of respiratory tract disease in paediatric-age subjects. PubMed was used to search for all studies published over the last 15 years using the following key words: "microbiota" or "microbioma" and "nasopharyngeal" or "respiratory" or "nasal" and "children" or "paediatric" or "infant". Analysis of the literature showed that respiratory microbiota can regulate health and disease development in the respiratory tract. Like the gut microbiota, the respiratory microbiota is established at birth, and early respiratory microbiota composition determines bacterial succession patterns and respiratory health in children. Protective and dangerous bacteria have been identified, and this can be considered the base for developing new approaches to diseases that respond poorly to traditional interventions. Reconstitution of missing microbes can be achieved by the administration of pre- and probiotics. Modulation of respiratory microbiota by favouring colonisation of the upper respiratory tract by beneficial commensals can interfere with the proliferation and activity of resident pathobionts and is a possible new measure to reduce the risk of disease. However, further studies are needed because a deeper understanding of these and related issues can be transferred to clinical practice.

Abstract
The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

Abstract
Pertussis is a highly contagious infectious disease caused by Bordetella pertussis that can be extremely serious, particularly in young infants. For many years the efforts of health authorities throughout the world to prevent pertussis had the main goals of reducing the morbidity of infants and children under 5 years of age, maintaining protection for several years during the school-age period and developing a significant herd immunity to directly and indirectly reduce the risk of the spread of the disease among young infants and the risk of transmission of the infection from preschool children to infants. However, the increased risk of B. pertussis infection among adolescents and adults due to the waning immunity to this bacterium induced by vaccines and natural infection seems to be the main reason for the resurgence of pertussis. We discuss the reasons for the administration of pertussis vaccines to individuals for whom they were previously not recommended, the expected results of the administration of additional pertussis vaccine doses and the differences in the administration of pertussis vaccines in different countries. An analysis of the literature revealed several reports indicating the need for the modification of immunization schedules against pertussis, with booster doses among adolescents and the need for the vaccination of pregnant women. However, to monitor the true epidemiology of pertussis, effective programmes to collect pertussis cases, adequate reporting systems and vaccination coverage monitoring should be urgently implemented.

Abstract
Obesity is a common condition that has rapidly increased in both the industrialised and developing world in recent decades. Obese individuals show increased risk factors for severe infections and significant immune system dysregulation that may impair the immune response to vaccines. The main aim of this paper was to review the current knowledge regarding the association between obesity and the risk and outcome of infections as well as immune response to vaccines. The results showed that obesity is a highly complex clinical condition in which the functions of several organ and body systems, including the immune system, are modified. However, only a small minority of the biological mechanisms that lead to reduced host defences have been elucidated. Relevant efforts for future research should focus on obese children, as the available data on this population are scarce compared with the adult population. Even if most vaccines are given in the first months of life when obesity is rare, some vaccines require booster doses at preschool age, and other vaccines, such as the influenza vaccine, are recommended yearly in the obese population, but it is not known whether response to vaccines of obese patients is impaired. The reduced immune response of obese patients to vaccination can be deleterious not only for the patient but also for the community.

Abstract
This paper reports the results of the first study in which Streptococcus salivarius 24SMB, a safe α-haemolytic strain capable of producing bacteriocin-like substances with significant activity against acute otitis media (AOM) pathogens, was intranasally administered in an attempt to reduce the risk of new episodes of AOM in otitis-prone children. In this prospective, randomized, double-blind, placebo-controlled study, 100 children aged 1-5 years with histories of recurrent AOM were randomized 1:1 to receive an intranasal S. salivarius 24SMB or placebo twice daily for 5 days each month for 3 consecutive months. Fifty treated children and 47 who received placebo who were compliant with study protocol were followed monthly for 6 months. The number of children who did not experience any AOM was higher among the children treated with the S. salivarius 24SMB preparation than among those in the placebo group (30.0 vs 14.9%; p = 0.076). Moreover, the number of children who received antibiotics during the study period was lower among the children treated with S. salivarius 24 SMB than among those who received placebo (70 vs 83.0%; p = 0.13). Compared with the children who were not colonized by S. salivarius 24SMB after treatment, the number of colonized children who experienced any AOM was significantly lower (42.8 vs 13.6%; p = 0.03). Similar results were observed when the children treated with antibiotics for AOM were analysed (67.8 vs 95.5%; p = 0.029). This study revealed the ability of intranasally administered S. salivarius 24SMB to reduce the risk of AOM in otitis-prone children.

Abstract
Oxygen and nitrogen radicals are frequently produced during viral infections. These radicals are not only a physiological mechanism for pathogen clearance but also result in many pathological consequences. Low concentrations of radicals can promote viral replication; however, high concentrations of radicals can also inhibit viral replication and are detrimental to the cell due to their mitogenic activity. We reviewed the detailed mechanisms behind oxygen and nitrogen radical production and focused on how viruses induce radical production. In addition, we examined the effects of oxygen and nitrogen radicals on both the virus and host. We also reviewed enzymatic and chemical detoxification mechanisms and recent advances in therapeutic antioxidant applications. Many molecules that modulate the redox balance have yielded promising results in cell and animal models of infection. This encourages their use in clinical practice either alone or with existing therapies. However, since the redox balance also plays an important role in host defence against pathogens, carefully designed clinical trials are needed to assess the therapeutic benefits and secondary effects of these molecules and whether these effects differ between different types of viral infections.

Abstract
Isolating genomic DNA from blood samples is essential when studying the associations between genetic variants and susceptibility to a given clinical condition, or its severity. This study of three extraction techniques and two types of commercially available cards involved 219 children attending our outpatient pediatric clinic for follow-up laboratory tests after they had been hospitalised. An aliquot of venous blood was drawn into plastic tubes without additives and, after several inversions, 80 microL were put on circles of common paper cards and Whatman FTA-treated cards. Three extraction methods were compared: the Qiagen Investigator, Gensolve, and Masterpure. The best method in terms of final DNA yield was Masterpure, which led to a significantly higher yield regardless of the type of card (p less than 0.001), followed by Qiagen Investigator and Gensolve. Masterpure was also the best in terms of price, seemed to be simple and reliable, and required less hands-on time than other techniques. These conclusions support the use of Masterpure in studies that evaluate the associations between genetic variants and the severity or prevalence of infectious diseases.

Abstract
The benefits of vaccination are clearly demonstrated by the eradication or enormous decline in the incidence of many vaccine-preventable diseases, but the coverage of many highly recommended vaccines is still frequently inadequate and children continue to suffer from diseases that could have been prevented. The main aim of this paper is to discuss the recognized barriers to the vaccination of children and adolescents confronting national health systems, providers and parents, and the ways in which they can be overcome. Most of the problems underlying limited vaccination coverage among children are due to a lack of understanding on the part of healthcare providers and parents, which underlines the need for educational programmes specifically addressed to each of these groups. It is also essential that all of the physicians providing immunization develop approaches that acknowledge parents' concerns and respectfully try to correct any misinformation. Other means of extending vaccine coverage include the implementation of adequate systems for recording vaccine administration and the activation of effective reminder/recall systems, the provision of immunization services in some medical care specialties or by integrating healthcare sites, and the elimination or reduction of all the problems that currently limit access to vaccination services. However, it will take the combined efforts of healthcare systems and providers to pull down all of the barriers.

Abstract
There is a certain consensus that some probiotics can significantly help in preventing and relieving the symptoms of gastrointestinal diseases and atopic diseases in general, but their use in respiratory tract infections has only been marginally investigated. The main aim of this review is to evaluate what is known about the impact of probiotics on pediatric respiratory tract infections in order to verify whether more data are needed before they can be used on infants and children with respiratory problems. Analysis of the literature shows that our knowledge is limited to the prevention of upper respiratory tract infections (URTIs). The very few studies carried out so far seem to indicate that probiotic administration may have some advantages in this regard, but the great limitation is that nothing is known about the susceptible micro-organisms or treatment regimens. Furthermore, URTIs are very limited clinical problems and it seems unreasonable to use a treatment whose efficacy and safety has not been completely clarified as means of preventing them. No data are available concerning the treatment of URTIs. There is a need for further research into the role of probiotics in treating respiratory infections and preventing more severe respiratory problems, including those involving the lower respiratory tract.

Abstract
There are few and partially discordant data regarding nasopharyngeal rhinovirus (RV) load and viremia, and none of the published studies evaluated the two variables together. The aim of this study was to provide new information concerning the clinical relevance of determining nasopharyngeal viral load and viremia when characterising RV infection. Nasopharyngeal swabs were obtained from 251 children upon their admission to hospital because of fever and signs and symptoms of acute respiratory infection in order to identify the virus and determine its nasopharyngeal load, and a venous blood sample was taken in order to evaluate viremia. Fifty children (19.9 %) had RV-positive nasopharyngeal swabs, six (12 %) of whom also had RV viremia: RV-C in four cases (66.6 %), and RV-A and RV-B in one case each. The RV nasopharyngeal load was significantly higher in the children with RV viremia (p < 0.001), who also had a higher respiratory rate (p = 0.02), white blood cell counts (p = 0.008) and C-reactive protein levels (p = 0.006), lower blood O2 saturation levels (P = 0.005), and more often required O2 therapy (p = 0.009). The presence of RV viremia is associated with a significantly higher nasopharyngeal viral load and more severe disease, which suggests that a high nasopharyngeal viral load is a prerequisite for viremia, and that viremia is associated with considerable clinical involvement.

Abstract
Bacterial infections are common in children with cancer and can lead to life-threatening complications. Infections in these patients mainly occur during neutropenic periods, and may be caused by Gram-positive or Gram-negative bacteria. The patients at highest risk of serious infections include those with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML), and those undergoing myeloablative hematopoietic cell transplantation (HCT). This is a review with the main aim of making a critical appraisal of the literature, and summarising what is currently known and can be recommended. The most significant studies support the use of floroquinolones (mainly ciprofloxacin) as the most rational approach to treat pediatric patients with probably long-lasting neutropenia, although trimetoprim-sulphametoxazole and amoxicillin/clavulanate may theoretically be valid alternatives. No prophylaxis seems to be needed for children with cancer without severe neutropenia. However, a global evaluation of the studies of antibiotic prophylaxis in children with cancer indicates that there are not enough data to prepare definite guidelines for its use or avoidance in pediatric oncology, and so further studies are needed. It is not only important to define the best antibiotic regimens for the children in whom such prophylaxis is useful, but also to identify precisely those who do not need it. This would avoid the antibiotic misuse that probably occurs at the moment because many low-risk children with cancer are treated. As prophylaxis against infections requires long-term adherence to an antibiotic regimen, the attitudes and beliefs of stakeholders need to be fully considered.

Abstract
Steroids have long been used to improve a number of clinical conditions because of their role in reducing inflammatory responses, but their use has always been limited because of their possible long-term side effects. The aim of this review is to establish whether steroids can have a positive effect on the outcome of some pediatric upper respiratory tract infections. We used PubMed to select all of the studies on topical or systemic steroids, and their therapeutic use in children with rhinosinusitis (RS), acute otitis media (AOM), otitis media with effusion (OME), acute pharyngitis (AP), or periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA), published over the last 15 years. Although a generally significant improvement in signs and symptoms has been observed with the use of intranasal steroids in children with RS, it is not clear which molecule should be recommended, how long treatment should be continued, or whether the benefits are limited to allergic children. No high-quality studies on the use of topical or systemic steroids in AOM have been carried out, and the results of studies of OME are controversial. The potential positive effects of steroids in children with AP are too slight to justify their use, and their possible adverse effects (particularly in the case of repeated administration) have not been clearly evaluated. Oral corticosteroids seem to be effective in resolving the symptoms of PFAPA, although they do not prevent future fever cycles. These findings show that further randomised and controlled studies are required in order to approach upper respiratory tract infections correctly and avoid the risks associated with frequent steroid use.

Abstract
Millions of people throughout the world are bitten by animals each year. About 90 % of the bites are caused by dogs and cats, and infections are the most common complications. As children are the most frequently bitten subjects, pediatricians should provide parents with everything they need to know in order to confront the problem. However, this does not seem to be case and, as the treatment of bite wounds is frequently inappropriate and delayed, the risk of acute infection and sequelae is increased. The main aim of this review is to discuss the epidemiology, microbiology, and clinical characteristics of infections due to dog and cat bites in children, and suggest the best approach to their management. Analysis of the published literature shows that prompt treatment is necessary in order to reduce the risk of infection. The therapeutic measures include wound washing, specific prophylaxis (i.e., tetanus and/or rabies), and antibiotics in the case of immunocompromised patients or deep wounds (particularly if there is evidence of edema or crushing), facial bites, or any wound over a tendon or bone.

Abstract
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.

Abstract
It has recently been shown that vitamin D (VitD) plays an important role in host defences, inflammation and immunity. We reviewed PubMed and selected all of the studies published over the last 15 years concerning VitD deficiency and VitD supplementation in children with respiratory tract infections. Our analysis showed that VitD seems to be very important because of its part in the complexity of the immune system. However, there are few pediatric studies and most have various limitations. First of all, the literature mainly refers to studies concerning the prevalence of VitD insufficiency and deficiency in specific pathologies. Secondly, it is extremely difficult to identify a common specific range of normal, insufficient and deficient VitD levels. Thirdly, the available studies of VitD supplementation often combined VitD with the use of other micronutrients, thus obscuring the role of VitD itself. Finally, different doses have been used for VitD supplementation. These observations clearly highlight the fact that further studies are needed to evaluate the impact of VitD deficiency and insufficiency in terms of the epidemiology and outcomes of pediatric respiratory tract infection, and whether VitD supplementation favours a positive outcome.

Abstract
Allergic rhinitis (AR) is a very common childhood disease that is associated with a significant reduction in the patients' quality of life. Its treatment combines educating the patients and their parents, immunotherapy and drug administration. However, even the best approach does not relieve the symptoms of a number of patients. Alternative therapies are particularly needed for children because the fear of adverse events frequently reduces parental compliance to the prescribed drugs, and immunotherapy is less easy to administer than in adults. In this prospective investigator-blinded study we evaluated whether children, with a documented history of seasonal grass pollen-related AR, benefit from nasal irrigation by assessing the effects on nasal signs and symptoms, on middle ear effusion and on adenoidal hypertrophy. We randomized children aged 5 to 9 years (median age 82 months) to normal saline or hypertonic saline (a 2.7% sodium chloride solution), administered twice-daily using a disposable 20 ml syringe, or no treatment. Nasal symptoms (rhinorrhea, itching, sneezing, nasal obstruction), swelling of turbinates, adenoid hypertrophy or middle ear effusion were assessed at baseline and after 4 weeks of treatment. Two hundred and twenty children (normal saline: 80; hypertonic saline: 80; no treatment: 60) completed the study. After four weeks, all the considered items were significantly reduced in the group receiving hypertonic saline (P < 0.0001), whereas in the group receiving normal saline only rhinorrhea (P = 0.0002) and sneezing (P = 0.002) were significantly reduced. There was no significant change in any of the items in the control group. The duration of oral antihistamines was significantly lower in the children receiving hypertonic saline than in those treated with normal saline or in controls. No adverse events were reported and parental satisfaction and compliance with the procedure were globally very good, regardless of the solution used. Using our procedure, hypertonic saline is effective, inexpensive, safe, well tolerated and easily accepted by children with seasonal grass pollen-related AR and their parents. Our data suggest that nasal irrigation with hypertonic saline might be included in the wide spectrum of therapies recommended for grass-pollen AR.

Abstract
PURPOSE To evaluate the microbiology of acute otitis media (AOM) with otorrhea due to spontaneous tympanic membrane perforation (STMP) in children living in Milan, Italy. METHODS We evaluated middle ear fluid (MEF) specimens taken from children affected by AOM associated with STMP and otorrhea between January 2001 and December 2011. The fluid was collected by means of direct swab sampling, sent for culture, and processed within 4 h. RESULTS A total of 705 specimens were obtained from 458 children (233 boys; mean age ± SD 28.3 ± 19.9 months), and were positive for bacteria in 487 cases (69.1 %). The most frequently cultured infectious agent in single-pathogen cultures was Haemophilus. influenzae (51.0 %), followed by Streptococcus pneumoniae (19.4 %), Streptococcus pyogenes (17.4 %), and Staphylococcus aureus (10.7 %). After adjusting for the sub-period of data collection, age, gender, and previous full heptavalent pneumococcal conjugate vaccine (PCV-7) schedule, it was found that the prevalence of H. influenzae slightly increased in 2008-2010, and the prevalence of S. pneumoniae significantly decreased over time (p = 0.02). CONCLUSIONS AOM with STMP is a particular form of AOM in which S. pyogenes plays a significant causative role although, as in uncomplicated cases, H. influenzae and S. pneumoniae retain their etiological importance. The frequency of the detection of S. aureus in MEF deserves further study because this pathogen can give rise to severe clinical problems. Finally, although the use of PCV-7 was relatively efficacious, the benefit of pneumococcal vaccination would be increased by vaccines including a larger number of serotypes.

Abstract
The administration of vaccines is not usually recommended in pregnant women because of a fear of severe adverse events for the fetus. However, contraindication to vaccination applies only to vaccines based on live attenuated viruses for the theoretical possibility that they might infect the fetus. In contrast, the use of several inactivated vaccines is useful and recommended. As a result of the transplacental passage of antibodies, maternal immunization can reduce the risk of vaccine-preventable diseases that may occur in the first months of life before the start or completion of the suggested vaccination schedule. One of the best examples is vaccination against influenza that can protect pregnant women from a disease that can lead to hospitalization and death in a significantly higher number of cases than in the general population and can induce protective specific antibody levels as well as being effective in infants in the first months of life. Other examples are vaccinations against tetanus, pertussis, pneumococcal infections and Haemophilus influenzae type b infection. This review analyses the advantages and limitations of maternal immunization as revealed by experience and the main publications.

The purpose of this investigation was to collect information regarding rhinovirus (RV) circulation in children with lower respiratory tract infections (LRTIs) in Burundi, Central Africa. We enrolled all of the children aged between 1 month and 14 years who were admitted to the hospital of Kiremba, North Burundi, with fever and signs and symptoms of LRTI (i.e., cough, tachypnea, dyspnea or respiratory distress, and breathing with grunting or wheezing sounds with rales) between 1 November 2010 and 31 October 2011, and obtained nasopharyngeal swabs for RV detection by means of polymerase chain reaction (PCR). The VP4/VP2 region of the positive samples was sequenced to determine the species of RV (A, B, or C). Four hundred and sixty-two children were enrolled: 160 (34.6 %) with bronchitis, 35 (7.6 %) with infectious wheezing, and 267 (57.8 %) with community-acquired pneumonia (CAP). RV infection was demonstrated in 186 patients [40.3 %; mean age ± standard deviation (SD) 1.77 ± 2.14 years]. RV infection was detected in 78 patients aged <12 months (40.0 %), 102 aged 12-48 months (44.3 %), and six aged >48 months (16.7 %; p < 0.01 vs. the other age groups). The most frequently identified RV was RV-A (81 cases, 43.5 %), followed by RV-C (47, 25.3 %) and RV-B (18, 9.7 %); subtyping was not possible in 40 cases (21.5 %). RV-A was significantly associated with bronchitis and CAP (p < 0.01) and RV-C with wheezing (p < 0.05). In Burundi, RVs are frequently detected in children with LRTIs. RV-A seems to be the most important species and is identified mainly in patients with bronchitis and CAP.

Abstract
Despite the availability of effective antibacterial agents and vaccines, pneumococcal meningitis and sepsis are still associated with high mortality rates and a high risk of neurological sequelae. We describe the case of a 17-month-old boy vaccinated with heptavalent pneumococcal conjugate vaccine (PCV7) who developed bacterial meningitis complicated by subdural empyema and deafness caused by Streptococcus pneumoniae serotype 7F. The 7F strain is not contained in PCV7 (the only vaccine on the market at the time of the onset of meningitis) but is included in the new pediatric 13-valent PCV, which may therefore prevent cases such as this in the future.

Abstract
Although relatively rare, meningococcal disease represents a global health problem being still the leading infectious cause of death in childhood with an overall mortality around 8%. Meningococcal meningitis is the most commonly recognized presentation, accounting for 80% to 85% of all reported cases of meningococcal disease (in half of these cases sepsis is also present concomitantly). The remaining 15-20% of cases are most commonly bloodstream infections only. Meningococcal serogroups A, B, and C account for most cases of meningococcal disease throughout the world. Recently, serogroups W-135 and X (predominantly in Africa) and group Y (in the United States and European countries) have emerged as important disease-causing isolates. Despite recent advances in medical management, the mortality rate of fulminant meningococcemia ranges from 15% to 30%. However, among survivors, 10-30% could have long term sequelae (i.e. sensoneural hearing loss, seizure, motor problems, hydrocephalus, mental retardation, and cognitive and behavioral problems). Considering the clinical severity of meningococcal disease, prevention represents the first approach for avoiding serious complications and possible deaths. The availability of new vaccines able to cover the emerging serotypes including A and Y as well as the availability on the market of new products that could prevent meningococcal B infection represent a great opportunity for the decrease of the burden of this complicated disease.

Abstract
Controlling environmental factors, chemoprophylaxis, immunoprophylaxis and surgery are considered possible means of preventing recurrent acute otitis media (RAOM), but there are no available data concerning the paediatric use of complementary and alternative medicine (CAM). We evaluated the uses of CAM (homeopathy and/or herbal medicine) as means of preventing AOM in children with a history of RAOM. Eight hundred and forty Italian children with RAOM (≥3 episodes in six months) aged 1-7 years were surveyed in 2009 using a face-to-face questionnaire, filled by parents or caregivers, that explored the prevalence, determinants, reasons, cost, and perceived safety and efficacy of CAM. About one-half (46%) of the children used CAM, significantly more than the number who used immunoprophylaxis (influenza vaccine 15%; p<0.05), PCV-7 34%; p<0.05) or chemoprophylaxis (2%; p<0.001). Use of CAM in the family was the only important factor positively associated with the use of CAM in children (adjusted OR 7.94; 95% CI: 5.26-11.99). The main reasons for using CAM were a fear of the adverse effects of conventional medicine (40%) and to increase host defences (20%). CAM was widely seen as safe (95%) and highly effective (68%). CAM prescribers were paediatricians in 50.7% of cases; self-initiation was reported by 23% of respondents. CAM expenditure was between Euro 25 and Euro 50/month in 27.6% of cases and ≥ Euro 50/month in 16%. Children with RAOM should be considered among the categories of subjects likely to be using CAM. Together with the fact that paediatricians are the main prescribers, this is worrying because of the current lack of evidence regarding the efficacy, safety and cost-effectiveness of CAM in the prevention of RAOM.

Abstract
OBJECTIVES Mycoplasma pneumoniae respiratory infection is a common cause of acute respiratory infection in children and adults. We evaluated the efficacy of increasing dosages of clarithromycin for the optimized therapy of M. pneumoniae respiratory infection in a mouse model. METHODS BALB/c mice were intranasally inoculated once with M. pneumoniae or SP4 broth (control). Groups of mice were treated with increasing dosages of clarithromycin (10, 25 or 75 mg/kg/day) or placebo subcutaneously daily. Groups of mice were evaluated after 1, 2, 3, 6 and 12 days of therapy. Outcome variables included quantitative M. pneumoniae culture, histopathological score of the lungs, bronchoalveolar lavage (BAL) cytokine/chemokine/growth factor concentrations and plethysmography after aerosolized methacholine to assess airway hyperresponsiveness. RESULTS Elevated dosages of clarithromycin resulted in greater antimicrobial efficacy with significantly reduced M. pneumoniae quantitative cultures (P < 0.05), as well as greater improvement in markers of disease severity with significantly reduced lung histopathology scores, BAL cytokine concentrations and airway hyperresponsiveness (P < 0.05). CONCLUSIONS Escalated dosing of clarithromycin resulted in significantly greater therapeutic efficacy in the treatment of experimental M. pneumoniae respiratory infection.

Abstract
Recurrent acute otitis media (rAOM) is frequently encountered in infants and children and the lack of any definitive treatment has led parents and physicians to try complementary and alternative therapies. We evaluated the efficacy of a propolis and zinc suspension in preventing AOM in 122 children aged 1-5 years with a documented history of rAOM, who were prospectively, blindly, randomized 1:1 to receive the suspension plus elimination of environmental risk factors or elimination of environmental risk factors only. AOM- and respiratory-related morbidity were assessed at study entry and every four weeks. In the 3-month treatment period AOM was diagnosed in 31 (50.8%) children given the propolis and zinc suspension and in 43 (70.5%) controls (p=0.04). The mean number of episodes of AOM per child/month was 0.23+/-0.26 in the propolis and zinc group and 0.34+/-0.29 in controls (reduction 32.0%, p=0.03). The administration of a propolis and zinc suspension to children with a history of rAOM can significantly reduce the risk of new AOM episodes and AOM-related antibiotic courses, with no problem of safety or tolerability, and with a very good degree of parental satisfaction. No effect can be expected on respiratory infections other than AOM.

Abstract
The objective of this document is to identify and reinforce current recommendations concerning the management of HIV infection in infants and children in the context of good resource availability. All recommendations were graded according to the strength and quality of the evidence and were voted on by the 57 participants attending the first Italian Consensus on Paediatric HIV, held in Siracusa in 2008. Paediatricians and HIV/AIDS care specialists were requested to agree on different statements summarizing key issues in the management of paediatric HIV. The comprehensive approach on preventing mother-to-child transmission (PMTCT) has clearly reduced the number of children acquiring the infection in Italy. Although further reduction of MTCT should be attempted, efforts to personalize intervention to specific cases are now required in order to optimise the treatment and care of HIV-infected children. The prompt initiation of treatment and careful selection of first-line regimen, taking into consideration potency and tolerance, remain central. In addition, opportunistic infection prevention, adherence to treatment, and long-term psychosocial consequences are becoming increasingly relevant in the era of effective antiretroviral combination therapies (ART). The increasing proportion of infected children achieving adulthood highlights the need for multidisciplinary strategies to facilitate transition to adult care and maintain strategies specific to perinatally acquired HIV infection.

Abstract
Pulmonary embolism is rare in children aged less than 15 years in whom its estimated annual incidence is 0.2 cases per 100,000, against the approximately 700 cases per 100,000 in patients aged more than 85 years. We describe the case of a 15-year-old girl who had a history of thrombocytopenia with anti-platelet and anti-nuclear antibodies. Misdiagnosed chest pain and dyspnea were treated for 6 weeks as community-acquired pneumonia, but proved to be the onset of pulmonary thromboembolism. Although this life-threatening event is rare in paediatrics, the presence of lupus anticoagulant combined with previously asymptomatic thrombocytopenia allowed a diagnosis of systemic lupus erythematosus (SLE). The combination of a history of thrombocytopenia and the presence of antinuclear antibodies, even in the absence of any other diagnostic criteria, should always suggest considering SLE as a differential diagnosis, particularly when the course of a clinical manifestation is atypical.

Abstract
Otitis media is a multifactorial disease. It represents a major public health burden, as it is the most common diagnosis in children and is characterized by both immediate and long-term morbidity. For years the knowledge about risk factors and microbiology of otitis media has been relatively stable. In recent years new data have been gathered regarding different microbiological aspects of otitis media. This new knowledge may contribute toward the development and implementation of therapeutic and preventive strategies.

Abstract
Rhinosinusitis is an inflammation of one or more paranasal sinuses, usually caused by an infection. The clinical appearance of rhinosinusitis may be heterogeneous and change with patient age, the duration of symptoms and, above all, the seriousness of the illness. The diagnosis of rhinosinusitis should only be based on anamnestic and clinical criteria in children with serious or persistent symptoms of upper respiratory tract infection, or which appear within a short time of an apparent recovery. Imaging studies are not usually necessary to confirm a diagnosis of uncomplicated acute bacterial rhinosinusitis. Paranasal sinus computed tomography or magnetic resonance and optical fibre rhinoscopy are required in severe cases that do not respond to antibiotic therapy. Antibiotics are recommended in cases of mild acute bacterial rhinosinusitis as a means of accelerating the resolution of symptoms, and they are mandatory in severe acute cases in order to cure the disease and avoid the possible onset of severe complications.

Abstract
This case-control study of full-term newborns with presumed or proven bacterial infection compared the efficacy, safety and tolerability of switch antibiotic therapy and traditional completely intravenous antibiotic administration. there were 36 newborns treated with switch therapy (i.v. ampicillin + sulbactam combined with i.v. amikacin for 3 days followed by oral cefpodoxime proxetil for 5 days); there were 72 full-term newborns with the same characteristics as controls who received i.v. ampicillin + sulbactam combined with i.v. amikacin for 3 days followed by i.v. ampicillin + sulbactam alone for a further 5 days. the results showed that full-term newborns with presumed or proven bacterial infection initially treated with intravenous antibiotics can be switched to oral antibiotics after 3 days' therapy if physical and laboratory data indicate the disappearance of infection, thus significantly reducing the length of stay in the neonatal intensive care unit and significantly increasing breastfeeding, without having any negative clinical impact.

Abstract
BACKGROUND Systemic steroids have been advocated in addition to antimicrobial therapy for severe Mycoplasma pneumoniae pneumonia. We evaluated the efficacy of clarithromycin, dexamethasone, and combination therapy for M. pneumoniae respiratory infection. METHODS Mice infected with M. pneumoniae were treated with clarithromycin, dexamethasone, combined clarithromycin/dexamethasone, or placebo daily; mice were evaluated at baseline and after 1, 3, and 6 days of therapy. Outcome variables included M. pneumoniae culture, lung histopathologic score (HPS), and bronchoalveolar lavage cytokine, chemokine, and growth factor concentrations. RESULTS Clarithromycin monotherapy resulted in the greatest reductions in M. pneumoniae concentrations. After 3 days of treatment, combination therapy significantly reduced lung HPS compared with placebo, clarithromycin, and dexamethasone alone, whereas, after 6 days of therapy, clarithromycin alone and combination therapy significantly reduced lung HPS compared with placebo. Concentrations of interleukin (IL)-12 p40, RANTES, macrophage chemotactic protein-1, and cytokine-induced neutrophil chemoattractant were significantly lower in mice treated with clarithromycin alone and/or combination therapy compared with dexamethasone alone and/or placebo; combination therapy resulted in a significantly greater reduction than clarithromycin alone for IL-12 p40 and RANTES. CONCLUSIONS Although monotherapy with clarithromycin had the greatest effect on reducing concentrations of M. pneumoniae, combination therapy had the greatest effect on decreasing levels of cytokines and chemokines as well as pulmonary histologic inflammation.

Abstract
In order to evaluate the infectious agents associated with the first episode of severe acute wheezing in otherwise healthy infants and to define the role of each of them in recurrences, 85 patients in Italy, aged <12 months, hospitalized because of a first acute episode of wheezing, were prospectively enrolled between 1 October 2005 and 31 March 2006. Upon enrollment, nasopharyngeal swabs were collected for the real-time PCR detection of respiratory syncytial virus (RSV) types A and B, influenza virus types A and B, adenovirus, parainfluenza viruses types 1, 2, 3 and 4, rhinovirus, human metapneumovirus, human coronavirus types 229E, OC43, NL63, and HKU1, bocavirus, enterovirus, and paraechovirus; nasopharyngeal aspirates were also obtained to detect atypical bacteria. At least one infectious agent was identified in 76 children (89.4%). RSV was the most frequently detected pathogen and its prevalence was significantly higher than that of the other pathogens in both age groups, and significantly higher in the children aged 3-12 months than in those aged <3 months. Only the children with RSV infection experienced recurrent wheezing. Viral load was significantly higher in children with than in those without recurrent wheezing. This study shows that RSV is the main reason for hospitalization during the first wheezing episode in infants, and that it appears to be the only pathogen associated with a high frequency of recurrences. A high viral load seems to be strictly related to the likelihood of recurrence.

Abstract
The aim of this study was to verify the frequency of atypical bacterial infections in children undergoing tonsillectomy because of severely recurrent acute tonsillopharyngitis (AT) and the possible benefit of surgery in cases in which Mycoplasma pneumoniae and Chlamydophila pneumoniae seem to play a role in causing the recurrences. A total of 118 patients (76 males; mean age +/- standard deviation, 6.67 +/- 3.31 years) were enrolled: 59 underwent tonsillectomy because of severely recurrent AT and 59 underwent adenotonsillectomy because of obstructive sleep apnea syndrome (OSAS). The results show, for the first time, that the great majority of children with a history of severely recurrent AT (and, therefore, considered to be eligible for elective tonsillectomy) are infected by atypical bacteria, mainly M. pneumoniae, and that tonsillectomy seems to be effective in reducing the recurrence of both AT and acute respiratory disease during 12 months follow-up postsurgery.

Abstract
Rhinosinusitis is a common children's disease. Most cases are acute, follow an episode of common cold, and are the consequence of a superimposed bacterial infection. If mild, they are characterized by the persistence of signs and symptoms of upper respiratory tract disease for more than 10 days; if severe, they involve fever and a purulent nasal discharge, and can cause a substantial decline in general health. Recurrent acute or chronic cases are usually diagnosed in children with predisposing factors, such as recurrent respiratory tract infections, allergic rhinitis, cystic fibrosis, immunodeficiency, ciliary dyskinesia, anatomic abnormalities or reflux. Therapy is based on antibiotics, administered orally in mild, and intravenously in severe cases. On the basis of recently highlighted antibiotic resistances and the possibility of spontaneous resolution, experts agree in considering amoxicillin the drug of choice for mild cases, and an antibiotic capable of overcoming all possible resistance for severe cases.

Abstract
Rhinosinusitis is a common childhood respiratory infection. Children have approximately six to eight viral infections of the upper respiratory tract each year, 5-13% of which may be complicated by a secondary bacterial infection of the paranasal sinuses. The diagnosis of acute bacterial rhinosinusitis in children is established by the persistence of purulent nasal or post-nasal draining lasting at least 10 days, especially if accompanied by supporting symptoms and signs, at which point antibiotic treatment has to be recommended. Appropriate antibacterial therapy should also be recommended if the draining has been present for less time, but is concomitantly associated with significant fever and localized signs of sinus inflammation in a child who appears ill. Imaging studies are not necessary to confirm the diagnosis of clinical rhinosinusitis for the purposes of treatment, but should be reserved for cases in which the diagnosis is in doubt or a complication is suspected, and for patients with recurrent or chronic rhinosinusitis. Under these circumstances, computed tomography is the preferred evaluation. Together with their clinical judgment, these suggestions may be useful for pediatricians in diagnosing this common condition.

Abstract
A study was carried out on 2,696 Italian children, aged 0-14 years. The goals were: (1) to define the age-related impact of acute respiratory infections (ARI), measured as the risk of attendance at the Paediatric Emergency Room, (2) to better define the importance and proportion of influenza and respiratory syncytial virus (RSV) infections and (3) to acquire deeper knowledge of the influenza strains circulating in infants and children. A standardised emergency unit attendance risk (EUAR) was calculated, by age group for ARI. Specific EUARs were also calculated for the two pathogens. Pharyngeal swabs were tested by polymerase chain reaction (PCR) for influenza and RSVs. Isolation in Madine-Darby canine kidney cells (MDCK) and Hep cells, haemagglutination inhibition (HI) testing and HA1 gene sequence analysis were performed for influenza viruses. Most of the patients enrolled were aged 0-5 years, 1,139 (84.6%) and 1,061 (78.5%) in the two seasons, respectively. The most represented age class was that of 1 year olds (331 cases in 2001-2002 and 301 in 2002-2003). The highest EUAR for ARI was in patients aged 0-3 years (16.8 and 12.9 during the two seasons). The same was observed on calculating this risk by specific pathogens: 17.4 and 5.5 for influenza and 13.0 and 12.7 for RSV. Virological analysis was performed on 2,696 samples, 595 of which proved positive (22%). The highest number of isolates (326) came from patients aged 1-3 years. RSVs were more often identified than influenza viruses in infants aged up to 1 year (32 vs. 20 isolates). Of 265 strains isolated in 2001-2002, 103 were RSVs (87 type A, 16 B) and 162 were influenza (90 type A, 72 B). HI showed that influenza B viruses were related to two lineages, B/Victoria/2/87 (32%) and B/Yamagata/16/88 (68%). Of 330 strains isolated in 2002-2003, 102 were RSVs (91 type A, 11 B) and 228 were influenza viruses (220 type A, 8 B). A/H3N2 strains belonged to two clusters, A/Panama/2007/99-like and A/Fujian/411/02-like, a new variant. This paper discusses the possible role of the identified flu strains in determining EUARs among the population by age class.
