Back to the Future: Intravenous Fosfomycin is Safe and Effective for the Treatment of Complicated Infections in Children

BACKGROUND

Despite its broad spectrum and excellent safety profile, fosfomycin is still rarely used in pediatrics, with very limited experience from clinicians.

METHODS

We retrospectively reviewed the medical records of all children admitted to Bambino Gesù Children's Hospital, IRCCS, Rome, Italy, and treated with fosfomycin for any serious infection. Children with immunodeficiency and oncologic diseases were excluded. Of each, we reported and analyzed demographic and clinical data.

RESULTS

The clinical charts of 20 patients were reviewed and analyzed. The mean age was 10.2 years. Most children were males (85%). Most patients treated had an osteo-articular infection (65%). In our sample, 7 patients (35%) had an underlying comorbidity. The causative agent was isolated in 14 cases (70%). All patients were treated with a combination of 2-3 antibiotics, including fosfomycin. The average duration of antibiotic treatment was 18 days. After treatment, 8 patients (40%) experienced a mild adverse reaction, possibly correlated with the administration of fosfomycin. All patients were discharged in good clinical condition.

CONCLUSIONS

The present study reports on a sample of pediatric patients with complicated infections where administration of fosfomycin led to eradication of the disease with little or no side effects. Role of the underlying condition and concomitant medication in causing the reaction could not be ruled out. These data suggest that fosfomycin is an effective and safe antibiotic in the pediatric population, particularly for deep-seated infections sustained by multi-drug resistant pathogens.

Pediatric torticollis: clinical report and predictors of urgency of 1409 cases

BACKGROUND

To date, the etiology and risk factors of torticollis are still poorly defined in the pediatric literature. Especially in the Emergency Department (ED) scenario, it is critical to reliably distinguish benign and transient conditions from (potentially) life-threatening disorders. This study describes the clinical characteristics of a large sample of children with torticollis. The aim of our study was to detect epidemiology, etiology and predictive variables associated with a higher risk of life-threatening conditions in acute torticollis.

METHODS

We conducted a pediatric retrospective study of acute torticollis over a 13-year period referred to the ED of a tertiary pediatric Hospital. We reported the characteristics in the overall sample and in two subgroups divided according to urgency of the underlying condition. Furthermore, we developed a multivariate model aimed at identifying the main clinical predictors of the need for urgent care.

RESULTS

1409 patients were analyzed (median age 5.7 years, IQR 5.8). A history of trauma was present in 393 patients (27.9%). The symptom most frequently associated with torticollis were pain (83.5%). At least one pathological finding was found in 5.4 to 7.9% of patients undergoing further imaging. Hospitalization was required in 11.1% of cases (median duration 4 days). The most frequent etiologies of torticollis were postural cause (43.1%), traumatic (29.5%), and infective/inflammatory (19.1%). A longer time from onset of torticollis and the presence of headache or vomiting were strongly correlated with an underlying urgent condition, after adjusting for the other clinically and statistically significant variables in the bivariate analysis.

CONCLUSION

Our study shows that an urgent condition most commonly occur in patients presenting with history of trauma or headache, vomiting and torticollis for more than 24 h should undergo further diagnostic evaluation and short-term follow-up, restricting invasive or expensive investigations to patients with clinical suspicion of an underlying harmful condition.

Use of Remdesivir in children with COVID-19: report of an Italian multicenter study

BACKGROUND

COVID-19 is generally milder in children than in adults, however severe infection has been described in some patients. Few data are available on use of Remdesivir (RDV) in children, as most clinical trials focused on adult patients. We report a multicenter study conducted in 10 Italian Hospitals to investigate the safety of RDV in children affected by COVID-19.

METHODS

We collected the clinical data of children with COVID-19 treated with RDV between March 2020 and February 2022 in 10 Italian hospitals. Clinical data were compared according to a duration of RDV therapy more or less than 5 days. Linear regression model was used to determine the association of significant variables from the bivariate analysis to the duration of RDV therapy.

RESULTS

A total of 50 patients were included, with a median age of 12.8 years. Many patients had at least one comorbidity (78%), mostly obesity. Symptoms were fever (88%), cough (74%) and dyspnea (68%). Most patients were diagnosed with pneumonia of either viral and/or bacterial etiology. Blood test showed leukopenia in 66% and increased C-reactive protein (CRP) levels in 63% of cases. Thirty-six patients received RDV for 5 days, nine patients up to 10 days. Most children who received RDV longer were admitted to the PICU (67%). Treatment with RDV was well tolerated with rare side effects: bradycardia was recorded in 6% of cases, solved in less than 24 h after discontinuation. A mild elevation of transaminases was observed in 26% of cases, however for the 8%, it was still detected before the RDV administration. Therefore, in these cases, we could not establish if it was caused by COVID-19, RDV o both. Patients who received RDV for more than 5 days waited longer for its administration after pneumonia diagnosis. The presence of comorbidities and the duration of O2 administration significantly correlated with the duration of RDV therapy at the linear regression analysis.

CONCLUSION

Our experience indicates that RDV against SARS-CoV-2 is safe and well-tolerated in pediatric populations at high risk of developing severe COVID-19. Our data suggest that delaying RDV therapy after diagnosis of pneumonia may be associated with a longer duration of antiviral therapy, especially in patients with comorbidities.

Acute Pupillary Disorders in Children: A 10-Year Retrospective Study of 101 Patients

BACKGROUND

To date, no study has specifically examined children with acute-onset pupillary motility disorders (APMD). Especially in the Emergency Department (ED), it is crucial to distinguish benign and transient conditions from life-threatening or urgent conditions (UCs). The aim of the study is to describe the clinical characteristics of children with APMD and their association with an increased risk of UCs.

METHODS

We conducted a pediatric retrospective study of APMD referred to ED over a 10-year period. We described the characteristics in the overall sample and in two subgroups divided according to urgency of the underlying condition. Furthermore, we applied a logistic regression model to identify the variables predictive of LT condition.

RESULTS

We analyzed 101 patients. In 59.4%, the APMD was isolated. In patients with extra-ocular involvement, the most frequently associated features were altered consciousness, headache, and vomiting. Exposure to toxic agents was reported in 48.5%. Urgent conditions occurred significantly more frequently in older children, presenting bilateral APMD and/or other ocular or extra-ocular manifestations.

CONCLUSIONS

Our study shows that UCs most commonly occur in patients presenting with bilateral APMD and other associated features. In unilateral/isolated APMD ophthalmological examination, exclusion of toxic exposure and observation until resolution of symptoms should be recommended.

Oral Viscous Budesonide in Children With Eosinophilic Esophagitis After Repaired Esophageal Atresia: A Clinical Trial

OBJECTIVES

A high prevalence of eosinophilic esophagitis (EoE) has been reported in children with repaired esophageal atresia (EA). Topical steroids proved to be an effective and safe therapy in EoE, although not approved in pediatrics. We report the results of the first clinical trial of oral viscous budesonide (OVB) performed in children with EoE after repaired esophageal atresia (EoE-EA).

METHODS

This open-label, single-arm, phase 2 clinical trial with randomized pharmacokinetic sampling, was conducted at the Bambino Gesù Children's Hospital between September 2019 and June 2021. EoE-EA patients received an age-banded dose of OVB twice daily for 12 weeks and were endoscopically evaluated. The primary endpoint was the rate of patients achieving histological remission. Secondary endpoints included clinical and endoscopic benefit after treatment, and safety assessments.

RESULTS

Eight consecutive EA-EoE patients were enrolled (median age 9.1 years, interquartile range 5.5). Of these, 5 received 0.8 mg and 3 received 1.0 mg twice daily of OVB. Histological remission was obtained in all but 1 patient (87.5%). The clinical score showed significant improvement at the end of treatment in all patients. No endoscopic features of EoE were found after treatment. No treatment-emergent adverse event occurred.

CONCLUSION

OVB is an effective, safe, and well-tolerated formulation of budesonide for use in pediatric patients with EoE-EA.

Drug self-poisoning in adolescents: A report of 267 cases

Introduction

The current study aims at describing a sample of adolescents admitted to a tertiary referral pediatric hospital for drug self-poisoning and to identify variables that could explain and predict a higher severity of intoxication.

Methods

We retrospectively reviewed the cases of drug self-poisoning in adolescents admitted to the Bambino Gesù Children's Hospital between January 2014 and June 2022 requiring consultation by the local Pediatric Poison Control Center (PPCC). We reported the type and class of drug ingested and correlated the clinical characteristics of the patients with their Poison Severity Score.

Results

The data of 267 patients were reported. Most patients were female (85.8 %), with a median age of 15.8 years at presentation. Half of the patients were symptomatic at admission (44.2 %), and most had at least one psychiatric comorbidity (71.1 %). Most patients were hospitalized (79.6 %), 16.6 % of cases required antidote administration and a minority required intensive care. Most patients received a PSS score of 0 (59.6 %). The most frequently ingested drug was acetaminophen (28.1 %) followed by ibuprofen (10.1 %) and aripiprazole (10.1 %). Antipsychotics as a class were the most abused drugs (33.1 %). The correlation of clinical variables with the PSS showed that older and male patients were more prone to be severely intoxicated.

Conclusions

This single-center study identifies the most commonly ingested drugs in a large sample of adolescents with voluntary drug self-poisoning, also showing that older and male patients are more susceptible to severe intoxication.

Relationship between viral load and symptoms in children infected with SARS-CoV-2

BACKGROUND

The purpose of this study is to evaluate the association between SARS-CoV-2 viral load in respiratory secretions of infected children and signs/symptoms of COVID-19.

METHODS

We reported the clinical characteristics of SARS-CoV-2-infected children during the study period. We compared viral load for several clinical variables, performed a predictive linear regression analysis to identify signs and symptoms significantly associated with viral load, and searched for discriminant viral load thresholds for symptomatic versus asymptomatic infections based on receiver-operating characteristics.

RESULTS

A total of 570 patients were included. The median age was 4.75 years. Comparison of CT values by dichotomous variable showed higher viral loads in children with fever, respiratory symptoms, and previous exposure to SARS-CoV-2. The linear regression analysis confirmed a significant relationship between the CT value with these variables and with age, other symptoms, and asymptomaticity. In particular, infants with fever and SARS-CoV-2 exposure had higher viral loads. No viral load cut-offs were found to distinguish symptomatic from asymptomatic patients.

CONCLUSION

Our study shows that fever, SARS-CoV-2 exposure, and respiratory symptoms are associated with higher viral load in children, especially infants, while age, presence of nonrespiratory symptoms, or absence of any symptoms are associated with lower viral load.

IMPACT

Key message: the clinical variables that best predict viral load in infected children are history of previous exposure to a SARS-CoV-2-infected person and presence of fever and respiratory symptoms (higher viral load). Added value to the current literature: this is the first article to prove this point.

IMPACT

SARS-CoV-2 viral load should not be used as a measure of clinical severity of COVID-19 in the pediatric population; however, lower viral load appears to be associated with asymptomatic COVID-19 in older children.

Adverse drugs reactions to paracetamol and ibuprofen in children: a 5-year report from a pediatric poison control center in Italy

BACKGROUND

This study aimed to analyze all the patients who contacted the hospital's pediatric poison control center (PPCC) for exposure to ibuprofen and acetaminophen, in order to assess the incidence of any adverse reactions.

METHODS

We retrospectively reported the clinical data of children who accessed the PPCC of the Bambino Gesù Children's Hospital, IRCCS, Rome, from January 1, 2018 to September 30, 2022 due to wrong, accidental or intentional intake of inappropriate doses of acetaminophen and/or ibuprofen. In addition, we compared patients according to the intake of one of the two drugs and reported the trimestral distribution of cases during the study period.

RESULTS

A total of 351 patients accessed the PPCC during the study period. The median age was 3.0 years. Most patients were females (57.8%). The most common reason for inappropriate oral intake of paracetamol or ibuprofen was a wrong use or an accidental intake (78.6%), with a fifth of patients taking the drug with suicidal intent (21.1%). According to the PPCC evaluation, most patients were not intoxicated (70.4%). Hospitalization was required for 30.5% of patients. Adverse reactions were reported in 10.5% of cases, with a similar incidence in patients who took paracetamol or ibuprofen. Nausea and vomiting were the most commonly reported adverse reactions. A higher frequency of moderate intoxication was found in patients who took paracetamol compared to ibuprofen (p = 0.001). The likelihood of intoxication was also higher in the paracetamol cohort. A spike of cases was registered at the end of 2021.

CONCLUSIONS

We analyze exposures to the two most commonly used pediatric molecules, paracetamol and ibuprofen, to assess the frequency of adverse reactions. We demonstrated that these relatively "safe" drugs may be associated with intoxications and adverse reactions when inappropriately administered.

Early Naso-Gastric Feeding and Outcomes of Anorexia Nervosa Patients

Nutritional rehabilitation with weight restoration is an important step in patients hospitalised for anorexia nervosa (AN). Naso-gastric feeding (NGF) should be considered when oral nutrition (OF) and oral nutritional supplementation (ONS) are insufficient. We evaluated the role of NGF on short- and long-term outcomes, considering weight gain, the length of hospitalisation (LOS) and the time to relapse. We report on the characteristics of patients under 18 years of age with AN admitted to the Department of Emergency and Acceptance of the Bambino Gesù Children's Hospital, IRCCS, Rome, between March 2019 and August 2022. Three hundred and fifteen patients were enrolled. We compared patients treated with NGF (group A) and patients without NGF (group B). Group A was characterised by a significantly lower BMI on admission and discharge, more frequent use of inpatient psychotropic therapy (IPDT) and longer hospital stay. The time to relapse was significantly longer in group A compared to group B. An early NGF setting correlates with a longer time to relapse and may be associated with a shorter LOS. A high caloric intake with a balanced nutritional formula provided by NGF allows an earlier recovery. The main advantages of this approach could be the rapid discharge of patients and a more effective psychological and social recovery.

Early echocardiographic evaluation of children admitted to the emergency department for anorexia nervosa during the COVID-19 pandemic

PURPOSE

Anorexia nervosa (AN) is the most frequent eating disorder (ED), whose cardiac complications may have life-threatening consequences for both the physical and psychological health of affected children. In this study, we reported and analysed the echocardiographic anomalies found in pediatric patients diagnosed with AN.

METHODS

We reported the demographic and clinical characteristics of children aged 8 to 18 years, who were diagnosed with AN and underwent a complete cardiological evaluation at the Emergency Department of the Bambino Gesù Children's Hospital, IRCCS, Rome between the 1st January 2021 and the 30th June 2021. Furthermore, we compared the patients according to the presence of pericardial effusion and a BMI (body mass index) cut-off 14.5 kg/m2.

RESULTS

Forty-nine patients were included in the study. The mean age was 15.1 years. Most patients were female (89.8%). The mean length of hospitalization was 18 days. The mean BMI at admission was 14.8 kg/m2, with a median weight loss of 9 kg in the last year. Eleven patients (22.4%) presented with cardiovascular signs or symptoms at admission. Most patients had pericardial effusion on heart ultrasound, with a mean thickness of 6 mm (SD ± 4). The LV (left ventricle) thickness over age was significantly higher in patients with pericardial effusion, with a Z score of -2.0 vs -1.4 (p = 0.014). The administration of psychiatric drugs was significantly more frequent in patients with a lower BMI (37.5% vs 12%, p = 0.038).

CONCLUSION

Our study suggests that a non-urgent baseline echocardiographic evaluation with focus on left-ventricular wall thickness and mass in children with anorexia nervosa is advisable.

Psychiatric comorbidities and dehydration are more common in children admitted to the emergency department for eating disorders in the COVID-19 era

PURPOSE

Since the beginning of COVID-19 pandemic, social distancing and home confinement had a significant impact on children, especially on those with eating disorders (ED). The primary objective of this retrospective study was to describe and analyze the demographic and clinical profiles of children presenting with ED during the COVID-19 pandemic.

METHODS

We conducted a retrospective review of clinical charts of patients with ED younger than 18 years who accessed the emergency department of the Bambino Gesù Children's Hospital, Rome, between March 2019 and March 2021. Of these, we reported and compared the demographic, clinical and laboratory data before and after the COVID-19 pandemic and looked for predictors of ED severity.

RESULTS

A total of 211 admissions for ED were recorded. The patients, mostly females (86.3%) were on average 14.1 years old. The mean weight loss on admission was 11 kg. Bradycardia was observed in 31.3% of the study sample. 16.6% of patients had an associated psychiatric disorder and 60.2% required psychotropic drugs. 68.7% of the patients required hospitalization. Respectively, 96 and 115 patients were admitted before and during the COVID-19 pandemic. The latter were hospitalized more (78.3 vs 57.3%; p = 0.001), yet for less time (19 vs 26 days; p = 0.004), had a higher mean serum creatinine (0.68 vs 0.47; p < 0.001) and were more frequently diagnosed with an associated psychiatric disorder (23.5 vs 8.3%; p = 0.003).

CONCLUSION

Our study shows a significant increase of hospitalizations of children with ED during the COVID-19 pandemic, along with a shorter length of stay, more psychiatric comorbidities, and some distinctive features at the laboratory work-up, such as an increase of serum creatinine and/or a reduction of serum albumin.

Clinical report and predictors of sequelae of 319 cases of pediatric bacterial osteomyelitis

Pediatric osteomyelitis is an insidious disease that can lead to permanent sequelae, the management of which still relies on lengthy intravenous antibiotic therapy. The purpose of this study is to report and describe the clinical course and outcome of pediatric bacterial osteomyelitis in our experience. We reported the clinical, diagnostic, and treatment characteristics of all cases of osteomyelitis in children younger than 18 years of age who were hospitalized between January 2010 and December 2021 at the Bambino Gesù Children’s Hospital in Rome, Italy, we compared patients with and without complications at follow-up, to identify any predictive factor for sequelae. The study sample included 319 cases of pediatric bacterial osteomyelitis. The median age was 7.77 years. Males (60.8%) were more affected than females. The most affected bones were the femur, tibia, and spine. Etiology was identified in 40.1% of cases, with S.aureus as the most common causative agent. Sequelae were reported in 43 cases (13.5%). The main predictors of sequelae were sepsis on admission and hypergammaglobulinemia. Our results show that a severe presentation with sepsis and hypergammaglobulinemia on admission may be associated with a higher frequency of late sequelae. Early recognition and aggressive treatment of this subgroup of patients may lead to a reduction in complications.

The pandemic within the pandemic: the surge of neuropsychological disorders in Italian children during the COVID-19 era

Background

Quarantine and isolation measures during COVID-19 pandemic may have caused additional stress and challenged the mental health of the youth. Aim of the study is to investigate the COVID-19 pandemic impact on neuropsychological disorders (NPD) of Italian children and adolescents to provide general pediatric recommendations.

Material and methods

A retrospective multicenter observational study was planned by the Italian Pediatric Society (SIP) to explore the impact of COVID-19 on the access of children to pediatric Emergency Departments (pED) for the evaluation of neuropsychological symptoms, collecting the classification codes of diagnoses between March 1, 2019 and March 2, 2021. The period study was split into two sub-periods: a pre COVID-19 period (from March 1 2019 to March 1, 2020) and a COVID-19 period (from March 2, 2020 to March 2, 2021). As additional information, data on NPD hospitalizations in any pediatric department of the involved centers were recorded.

Results

During the study period, a total of 533,318 children were admitted to the pED involved in the study. Despite a 48.2% decline of pED admissions, there was a significant increase (83.1%) in patient admissions for NPD. The most frequent NPD conditions which increased during the COVID-19 pandemic were suicidal ideation (+ 147%), depression (+ 115%), eating disorder (+ 78.4%), and psychosis (+ 17.2%). During the pandemic period, a 39.5% increase in NPD hospitalizations was observed as well. The NPD disorders that mostly required hospitalizations were suicidal ideation (+ 134%), depression (+ 41.4%), eating disorder (+ 31.4%), and drug abuse (+ 26.7%).

COVID-19 pandemic had a major impact on children's health, mainly on their NPD development. Neuropsychological assessment should be required at the primary level, in the pediatrician's office, to facilitate early capture of the sign of impairment and provide an adequate treatment.

Conclusion

SIP underlines the psychological consequences of COVID 19 pandemic on the youngest and recommends an early identification of NPD in the pediatric population to avoid other serious consequences for children's physical and mental health.

Acquired methemoglobinemia in children presenting to Italian pediatric emergency departments: a multicenter report

INTRODUCTION

Methemoglobinemia (MetHb) is a rare inherited or acquired cause of cyanosis in children. Owing to its rarity, case reports and case series are mostly available in the current literature. This study reports data on a large sample of children with acquired MetHb.

METHODS

Data on patients admitted for acquired MetHb between January 2007 to December 2020 was extracted from the databases of five Italian pediatric emergency departments (EDs). Demographical and clinical characteristics was reported and discussed.

RESULTS

Nineteen cases of acquired MetHb were evaluated. Ten patients (52.6%) were male and 9 (47.4%) were female. The median age was 8.23 months. The median time from trigger to symptom onset was 6 hours. Mostly, the intoxication presumptively occurred by home ingestion of contaminated food, mainly badly preserved vegetable broth. All patients were cyanotic at admission, most patients also presented tachycardia and/or tachypnea, and two patients were comatose. Antidotal therapy with methylene blue was given in 14 patients (73.7%). The median hospital stay was 2 days. All patients survived.

DISCUSSION

As MetHb leads to the pathognomonic brown blood discoloration, blood gas analysis is mandatory immediately upon hospital arrival of a cyanotic patient. A correct medical history is crucial to identify the trigger and remove it. In our sample, the age onset was much lower than in the previous literature, and MetHb mainly due to ingestion of contaminated vegetable broth. Methylene blue led to a rapid recovery in all patients. Oxygen therapy may well lead to complete recovery when methemoglobin levels do not exceed 30% in asymptomatic and 20% in mildly symptomatic patients.

CONCLUSIONS

The diagnosis and management of acquired MetHb in the emergency setting requires acknowledgment of this condition as a cause of cyanosis in the weaning child. Indeed, when promptly recognized and treated, this severe condition rapidly resolves with no significant acute sequelae.

Epidermolysis Bullosa in children: the central role of the pediatrician

Epidermolysis bullosa (EB) is a severe hereditary disease characterized by defective epithelial adhesion causing mucocutaneous fragility. The major types are EB simplex (EBS), junctional EB (JEB), dystrophic EB (DEB) and more than 35 EB subtypes. Another very rare type of EB is Kindler EB (KEB). Clinically, it is a very heterogeneous disease which ranges from localized to extensive skin lesions with frequent multisystem extra cutaneous involvement. The role of a pediatrician-dermatologist cooperation within a multidisciplinary team is fundamental for both the diagnosis and management contributing to these patients’ better life expectancy. Aim of this study is to describe clinical and laboratory characteristics of the main EB subtypes focusing on nutritional and gastrointestinal aspects, providing information to aid the paediatric management of children with EB. This retrospective study reviewed the cases of 160 pediatric EB patients (76 male and 84 female): 31 patients affected by EBS (mean age ± SD: 4.37 ± 7.14), 21 patients affected by JEB (mean age ± SD: 9.26± 17.30) and 108 with DEB (mean age ± SD: 11.61 ± 13.48). All patients were admitted at the Bambino Gesù Children’s Hospital in Rome, between June 2005 to June 2020. The reduced gastrointestinal absorption, chronic losses, esophageal stenosis and chronic inflammatory state, represent the basis of nutritional problems of EB patients. In particular, anemia represents one of the most important complications of DEB patients which could require transfusion-dependent patterns. Malnutrition, vitamin deficiencies and anemia have been related to growth delay in EB patients. A specific diet with a balance of all macronutrients is required and improving caloric intake with sugar limitations is fundamental to prevent dental caries and tooth decay typical of EB patients. While sepsis proved to be the major cause of morbidity and mortality in younger patients, squamous cell carcinoma was mostly observed in older patients, especially those affected by DEB. Patients with EB require regular monitoring for complications and sequelae with a frequency of evaluations which varies based on age and EB subtypes. Cooperation among medical teams involving paediatricians, dermatologists, specialist clinicians including nutritionists such as families and patient’s association is fundamental to approach the disease and improve the quality of life of these patients.

Italian consensus on the therapeutic management of uncomplicated acute hematogenous osteomyelitis in children

BACKGROUND

Acute hematogenous osteomyelitis (AHOM) is an insidious infection of the bone that more frequently affects young males. The etiology, mainly bacterial, is often related to the patient's age, but it is frequently missed, owing to the low sensitivity of microbiological cultures. Thus, the evaluation of inflammatory biomarkers and imaging usually guide the diagnosis and follow-up of the infection. The antibiotic treatment of uncomplicated AHOM, on the other hand, heavily relies upon the clinician experience, given the current lack of national guidelines for the management of this infection.

METHODS

A systematic review of the studies on the empirical treatment of uncomplicated AHOM in children published in English or Italian between January 1, 2009, and March 31, 2020, indexed on Pubmed or Embase search engines, was carried out. All guidelines and studies reporting on non-bacterial or complicated or post-traumatic osteomyelitis affecting newborns or children older than 18 years or with comorbidities were excluded from the review. All other works were included in this study.

RESULTS

Out of 4576 articles, 53 were included in the study. Data on different topics was gathered and outlined: bone penetration of antibiotics; choice of intravenous antibiotic therapy according to the isolated or suspected pathogen; choice of oral antibiotic therapy; length of treatment and switch to oral therapy; surgical treatment.

CONCLUSIONS

The therapeutic management of osteomyelitis is still object of controversy. This study reports the first Italian consensus on the management of uncomplicated AHOM in children of pediatric osteomyelitis, based on expert opinions and a vast literature review.

Social media use to improve communication on children and adolescent's health: the role of the Italian Paediatric Society influencers

Background

Fake news on children’s and adolescent health are spreading. Internet availability and decreasing costs of media devices are contributing to an easy access to technology by families. Public health organizations are working to contrast misinformation and promote scientific communication. In this context, a new form of communication is emerging social media influencers. Aim of this study is to evaluate the role of paediatric influencers (PI) in communicating information about children and adolescents’ health.

Materials and methods

A group of PI was enrolled from December 2019 to January 2020 by a scientific commission nominated by the Italian Paediatric Society (SIP). PI were asked to share Facebook messages from the official page of the SIP to their own network. Social media tools have been evaluated across 12 months, from July 28, 2019, to July 11, 2020. For the purposes of clarity, we schematically divided the study period as follows: the period of PIs activity (January 6, 2020, to July 11, 2020) and the period when PIs were not yet active (July 28, 2019, to January 4, 2020). Information on Facebook page (lifetime total likes, daily new likes, daily page engaged, daily total reach) and on published post (lifetime post total reach, lifetime post organic reach, lifetime engaged users) were evaluated.

Results

A significant increase in Facebook daily new likes, page engagement and total reach, as well as in lifetime post total and organic reach was evidenced. As for PI, they reported a positive experience in most cases.

Discussion

In the digital era, communication strategies are becoming more important, so that the scientific community has to be actively involved in social media communication. Our pilot study demonstrated that the recruitment of paediatric influencers has increased communication and interaction of the SIP Facebook page.

Conclusion

Our study shows the potential role of influencers: spreading health messages via PI seems to be a successful strategy to promote correct communication about children’s and adolescents’ health.

Prioritizing the First Doses of SARS-CoV-2 Vaccine to Save the Elderly: The Case Study of Italy

SARS-CoV-2 is currently causing hundreds of deaths every day in European countries, mostly in not yet vaccinated elderly. Vaccine shortage poses relevant challenges to health authorities, called to act promptly with a scarcity of data. We modeled the mortality reduction of the elderly according to a schedule of mRNA SARS-CoV-2 vaccine that prioritized first dose administration. For the case study of Italy, we show an increase in protected individuals up to 53.4% and a decrease in deaths up to 19.8% in the cohort of over 80's compared with the standard vaccine recalls after 3 or 4 weeks. This model supports the adoption of vaccination campaigns that prioritize the administration of the first doses in the elderly.

Predicting Parameters for Audiological Complications in Pediatric Patients Affected by Meningitis

Objective Meningitis is one of the most common causes of acquired sensorineural hearing loss in childhood. The aim of this study was to identify parameters predicting long-term audiological complications in meningitis.

Methods Patients under 18 years admitted to the Bambino Gesù Pediatric Hospital between March 2001 and February 2019 with a diagnosis of meningitis entered the study. Audiological complications had been investigated during hospitalization and at follow-up.

Results During the study period, 425 patients were enrolled. Sensorineural hearing loss was observed in 48 patients (11.3%). Multivariate analysis has shown that female gender predisposes to the development of permanent hearing loss after meningitis. Hearing impairment was associated with pneumococcal etiology (p < 0.001), lethargy (p = 0.027), reduced cerebrospinal fluid glucose level (26.18 mg/dL, p = 0.004), increase in both C-reactive protein (17.77 mg/dL, p = 0.001), and erythrocyte sedimentation rate (106.3 mm/h, p = 0.004). At follow-up, 19 patients had a persisting hearing damage, 7 recovered their hearing capacity and 20 were lost to follow-up. Among patients with permanent hearing damage, treatment was necessary in 16 patients. In details, 6 patients required external hearing aids and 10 patients required a cochlear implant.

Conclusions Female gender, lethargy at onset, reduced cerebrospinal fluid glucose level, increased inflammation index, and pneumococcal etiology are correlated with sensorineural hearing damage in meningitis patients.

Neonatal osteomyelitis: an Italian multicentre report of 22 cases and comparison with the inherent literature

OBJECTIVE

The primary objective of this study is to report and compare our data with the most relevant literature of the past decade about neonatal osteomyelitis.

STUDY DESIGN

We retrospectively review the data of 22 subjects aged 35 days or less who were admitted to three different sites in Italy with a radiological diagnosis of osteomyelitis. The inherent literature was searched and reviewed: five studies were considered for comparison with our data.

RESULTS

All the neonates, except three (two pre-term and one post-term), were born at term. The male to female ratio was 1.75 (14 males and 8 females). The mean age at presentation was 19.5 days. The most common presenting signs of the infection were local swelling and reduced mobility of the affected segment. The most common sites of infection were the femur, humerus, and tibia. The mean duration of intravenous antibiotic therapy was 29.5 days. In most neonates the diagnosis was prompt and the antibiotic treatment immediate. A low rate of sequelae was reported. All infants survived through follow up. The data from the inherent literature showed a wide variability, probably owing to the setting and the historical period of the different studies.

CONCLUSION

Neonatal osteomyelitis is an alarming yet poorly understood disease. Nonetheless, our report suggests that a quick diagnosis and treatment can be easily achieved, with good outcome on the remarkably plastic structure of neonatal bones.

Acute Exposure to European Viper Bite in Children: Advocating for a Pediatric Approach

Viper bite is an uncommon but serious cause of envenoming in Europe, especially in children. Our study aim is to better describe and analyze the clinical course and treatment of viper bite envenoming in a pediatric population. We retrospectively reviewed 24 cases of pediatric viper bites that were admitted to the Pediatric Emergency Department and the Pediatric Intensive Care Unit of the Bambino Gesù Children Hospital in Rome between 2000 and 2020. Epidemiological characteristics of the children, localization of the bite, clinical and laboratory findings, and treatment approaches were evaluated. The median age of the patients was 4.2 years, with male predominance. Most cases of viper bite occurred in the late summer. Most patients required admission to the ward for prolonged observation. The most common presenting signs were pain, local oedema, and swelling. Patients with a high severity score also had a significantly higher white blood cell count and an increase of INR, LDH, and CRP levels. No fatality was reported. Viper bite envenomation is a rare pediatric medical emergency in Italy but may sometimes be severe. A new pediatric severity score may be implemented in the screening of children with viper bites to favor a selective and prompt administration of antivenom.

Follow-up evaluation of the immunological status of children admitted for acute cerebral nervous system infections: a retrospective study

Background

Acute Cerebral Nervous System Infections (ACNS) may cause death or severe complications even to promptly treated children. The role of the immune system in influencing the course and the outcome of meningitis has been studied but it is not yet completely understood. The aim of the research is to ascertain whether children who experienced ACNS infection had a normal immune system.

Methods

Patients under 18 years of age admitted at Bambino Gesù Children from January 2006 till June 2016 for meningitis were asked to participate to the follow-up study. The immune status was evaluated both clinically and by laboratory investigations.

Results

Most of the patients over 3 years at follow up had at least one immunological alteration at follow-up evaluation (74%). Considering ACNS infection etiology, certain pathogens were almost exclusive of patients affected by some immunological alteration, regardless of their age.

Discussion

Our preliminary results indicate that sub-clinical immunological defects may be associated to ACNS pediatric infections. Moreover, to the best of our knowledges, this is the first study correlating pathogens to immune evaluation in ACNS infections. It is, however, important to underline the high frequency of persistent immunological alterations in the analyzed patients. Further studies are needed to confirm our conclusions.

Conclusions

We recommend an immunological assessment at follow up evaluation in children who experienced an ACNS infection.

Possible role of vitamin D in Covid-19 infection in pediatric population

PURPOSE

Covid-19 is a pandemic of unprecedented proportion, whose understanding and management is still under way. In the emergency setting new or available therapies to contrast the spread of COVID-19 are urgently needed. Elderly males, especially those affected by previous diseases or with comorbidities, are more prone to develop interstitial pneumonia that can deteriorate evolving to ARDS (acute respiratory distress syndrome) that require hospitalization in Intensive Care Units (ICUs). Even children and young patients are not spared by SARS-CoV 2 infection, yet they seem to develop a milder form of disease. In this setting the immunomodulatory role of Vitamin D, should be further investigated.

METHODS

We reviewed the literature about the immunomodulatory role of Vitamin D collecting data from the databases Medline and Embase.

RESULTS

Vitamin D proved to interact both with the innate immune system, by activating Toll-like receptors (TLRs) or increasing the levels of cathelicidins and β-defensins, and adaptive immune system, by reducing immunoglobulin secretion by plasma cells and pro-inflammatory cytokines production, thus modulating T cells function. Promising results have been extensively described as regards the supplementation of vitamin D in respiratory tract infections, autoimmune diseases and even pulmonary fibrosis.

CONCLUSIONS

In this review, we suggest that vitamin D supplementation might play a role in the prevention and/or treatment to SARS-CoV-2 infection disease, by modulating the immune response to the virus both in the adult and pediatric population.

Spondylodiscitis in Children: A Retrospective Study and Comparison With Non-vertebral Osteomyelitis

Objectives: The aim of this study is to provide new data on pediatrics spondylodiscitis for an optimal clinical management of this site-specific osteomyelitis. Methods: We reported 48 cases of pediatric spondylodiscitis and made three comparisons between: (1) tubercular and non-tubercular cases; (2) patients aged more or less than 5 years; (3) children with spondylodiscitis and 62 controls with non-vertebral osteomyelitis. Results: A higher rate of sequelae was reported in patients with tubercular spondylodiscitis, but no significant differences were noted at the cut-off of 5 years of age. Compared to non-vertebral osteomyelitis, pediatric spondylodiscitis affects younger children of both genders, usually presenting with afebrile back pain, and requiring longer time to admission, hospitalization, and antibiotic therapy. Conclusion: Pediatric spondylodiscitis is an insidious disease with a non-specific presentation in childhood and peculiarities of its own. However, when clinical remission is obtained by an early start of broad-spectrum antibiotics, prolonging the therapy does not improve, nor worsens, the outcome. Surgical management is mandatory in case of vertebral instability and neurological signs but can be avoided when the infection is promptly treated with antibiotic therapy.

Recurrent Wheezing in Pre-school Age: Not Only Airway Reactivity!

Background: About a fifth of all mediastinal masses are primary cysts arising in the absence of other underlying pathology. Bronchogenic cysts, although rare, are the most frequent type responsible for lower airways compression as they often develop in the peripheral branches of the tracheobronchial tree. Case presentation: We report the case of a 6-months-old child admitted for acute respiratory distress and wheezing not responsive to asthma treatment. Digestive and airway endoscopy proved a mild and a marked reduction of the esophageal and tracheal lumen, respectively. The nocturnal polygraphy showed an underlying obstructive disorder and the chest CT scan confirmed the presence of a wide mediastinal cyst compressing the trachea. The mass, later identified as a bronchogenic cyst, was surgically removed with complete resolution of the patient's respiratory symptoms. Discussion: Our case shows that differential diagnosis of wheezing in pre-school aged children should encompass causes others than airway reactivity, thus prompting further evaluation and management.

[Intra-arterial antiblastic treatment of breast carcinoma]

PURPOSE

To report our personal experience with the locoregional treatment of breast cancer.

MATERIAL AND METHODS

Eighteen patients aged 33-67 years (mean: 54 years) were treated with 31 sessions of intra-arterial antiblastic infusion, 5 of them for neoadjuvant purposes (Group 1), 5 for palliation in unresectable tumors (Group 2) and 8 for cutaneous recurrences after mastectomy (Group 3).

RESULTS

2/5 CR and 3/5 PR were obtained in Group 1; 2/5 lesions were made resectable and 3/5 RP obtained in stage III or unresectable lesions (Group 2). Finally, 3/8 CR, 3/8 PR, 1/8 SD and 1/8 PD were observed in Group 3. An objective response according to WHO criteria was demonstrated in 15/18 cases (88%). We had no post-treatment hematologic complications, but one patient presented focal subcutaneous sclerosis and one cutaneous necrosis.

CONCLUSIONS

The morphological efficacy of intraarterial antiblastic infusion in our series was similar to that of other series. No definitive conclusions can be drawn yet about clinical results and long-term survival. This poorly invasive and low risk procedure, which should be combined with other treatments, permits to reduce the extent of surgery and to treat skin recurrences.

[Locoregional therapy with hypoxic liver perfusion in malignant neoplasms of the gallbladder. Preliminary experience]

PURPOSE

We report four cases of advanced malignant cancer of the gallbladder treated with hypoxic hepatic perfusion.

MATERIAL AND METHODS

Hypoxic hepatic perfusion is currently used to treat diffuse hepatic metastases: the common hepatic artery is occluded with a balloon catheter and then a large amount of antiblastic solution is infused into the liver. Hypoxia and slow flow increase the effect of the drug on neoplastic tissue. Two sessions were performed in three patients with an interval ranging 2-4 months, while one patient underwent a single session. The drug was Mitomycin C, whose dose ranged 20-40 mg (mean: 30 mg). Blood filtration was performed after one of the six procedures only and can be considered unnecessary.

RESULTS

Acute gastric bleeding appeared in a patient after the embolization of the right gastric artery with bucrylate during the first session performed to avoid drug reflux into gastric wall arteries. No other technical or clinical complications occurred. An objective morphological response (tumor necrosis or reduction in size > 50%) was observed in all patients after the first session. CT findings were stable in two of three patients submitted to a second session, while local progression was observed in the other patient. Complete clinical response was achieved in all symptomatic patients. No WHO toxicity was observed.

DISCUSSION AND CONCLUSIONS

The rate of positive morphological and/or clinical responses after hypoxic perfusion was very high in our experience, even though our series was small. Recurrences were found in two patients some months later, which suggests the need of long-term follow-up. Hypoxic perfusion can be nevertheless considered as a new and interesting therapeutic approach for advanced malignant gallbladder cancer, with a strong short-term effect on the lesion and good results on clinical symptoms.

[Results of flow-controlled antiblastic perfusions (stop-flow technique) carried out with percutaneous technique: 30-month experience]

PURPOSE

We report the morphological and clinical results in a series of patients with advanced thoracopulmonary, abdominal, pelvic and lower limb tumors treated with stop-flow perfusion (SFP).

MATERIAL AND METHODS

We performed 77 SFPs with the percutaneous angiographic technique in 55 patients (25 women and 30 men; mean age: 53 years). Eighteen thoracic perfusions with aortocaval block (ASI) were performed in 11 patients, 33 abdominal hypoxic perfusions (HAP) in 26 patients, 17 hypoxic pelvic perfusion (HPP) in 11 patients and 9 hypoxic lower limb perfusions (HILP) in 7 patients. 42/77 procedures were followed by hemofiltration.

RESULTS

No technical complications were observed. Twenty-eight patients in our series are still alive (mean follow-up: 14 months) and 23 have died (mean survival: 8 months), 20/23 of them (87%) for disease progression. Three of 77 patients (3.8%) died within 7 days of the procedure (2 AS, 1 HAP). At CT or MR follow-up, responses > 50% were observed in 56% of the procedures and clinical CR was achieved in 53/77 patients (69%). In the subgroups classified by procedure, positive responses were observed in 56, 48, 59 and 78%, respectively for ASI, HAP, HPP and HLP. Clinical CR was observed in 67, 67, 71 and 78%, respectively. The death rate for disease progression relative to the overall death rate was 100, 86, 75 and 100%. Hematologic toxicity according to WHO criteria (mean: 2) was observed in 77% of the whole of procedures (59/77). Statistical analysis showed no relationship between morphological responses and type of antiblastic drug or previous antiblastic treatments.

CONCLUSIONS

SF procedures permit the effective control of many advanced tumors which cannot be treated otherwise, with a high rate of positive morphological and of complete clinical responses. The best results were obtained in hypoxic perfusion of the lower limb. The results were not correlated with previous antiblastic treatments. However, the high rate of sequels and the low hematologic tolerance of those procedures must be emphasized.

[Antiblastic hypoxic stop-flow perfusion in the treatment of liver metastasis: preliminary results]

PATIENTS AND METHODS

27 patients (14 men and 13 women aged 35 to 71 years; average: 59 years), with 3-11 months' follow-up (average: 5 months) were treated for hepatic metastases (17/22 from colorectal, 10/22 from other primary tumors) with hypoxic locoregional hepatic perfusion. Sixteen of 22 patients had been pretreated with resection, systemic chemotherapy or freeflow locoregional infusion. Our protocol consists in blocking arterial flow with an occlusion balloon catheter inflated in the hepatic artery; the main catheter channel is connected with a pump system and 250-300 ml saline with 30-40 mg Mitomycin C are perfused in the arterial hepatic system. Embolization with a gelatin sponge is performed after the end of perfusion.

RESULTS

19/27 patients are still alive, and 8/27 are dead but death was caused by the progression of intrahepatic disease in only 2/27 (7%). Iatrogenic lesions of the arterial wall were shown at follow-up DSA in 15/22 patients (56%). Thirteen CR (48%) and 9 PR (33%) were demonstrated at CT follow-up, amounting to 81% of objective responses. Follow-up showed a clinical CR in 12/18 symptomatic patients (66%). No case of hematologic toxicity was observed. Mean CEA values changed from 129 to 10.60. Twelve of 27 patients exhibited mild posttreatment sequels, none of them lasting longer than three days; ischemic cholecystitis was seen in 3/15 cases (14%).

CONCLUSIONS

The occlusion catheters on the market are not optimal for this procedure; the axillary percutaneous approach is advantageous. CR rate was very high in our series but the objective response rate doses do not differ from those in the series with free-flow procedures. The highest CR rate was observed in untreated patients and in hypervascularized lesions; the rate of clinical sequels was low, clinical CR rates were high and there was no hematologic toxicity. This well-tolerated procedure provides good local disease control, but the high rate of deaths from extrahepatic progression suggests that systemic chemotherapy and long-step intraarterial perfusion be combined.

[Antiblastic locoregional perfusion with control of the aorto-caval flow: technique of percutaneous access]

The authors introduce a new technique for performing aortic stop-flow infusion (ASI) or hypoxic abdominal perfusion (HAP) to treat advanced thoracoabdominal tumors, via an angiographic percutaneous approach. To date, the maneuver has always been performed with surgical exposure of vascular sites in the groins. The materials available on the market were initially used and then dedicated materials have been developed, such as 11-F vascular sheaths, 8-F catheters, latex balloons with maximum phi's of 4 cm and maximum capacity of 70 ml. We performed 72 maneuvers in 56 patients during 22 months. No technical or instrumental complications occurred and all treatments were successful. Three patients (6%) died within 12 hours, two because of ARDS following thoracic perfusion and one for acute renal failure and disseminated intravascular coagulation following abdominal perfusion. The percutaneous approach provides the same mechanical-occlusive efficacy for aortocaval occlusion and therefore the same therapeutic results as surgery, but it has fewer risks of technical complications and no technical failures. Moreover, this technique is more repeatable and less expensive than surgery and its hospital stay and recovery time are shorter. To conclude, the ASI/HAP procedure is an interesting therapeutic chance in otherwise untreatable advanced cancer patients offering several prospects of technical and pharmacologic development to further increase its efficacy.
