Background: The term "sharenting" describes the increasingly popular habit of parents to share photos, videos, or other information regarding their children on their social profiles, through online platforms. It is highly likely that many parents are posting content about their underage children online with little knowledge of the risks associated with this practice. This study aims to investigate whether variables such as parents' age, gender, marital status, occupation and educational level influence the practice of sharing child-related content and the degree of awareness. Methods: We performed a pilot cross-sectional study, based on an anonymous questionnaire. The questionnaire was administered to parents of underage children attending the pediatric outpatient clinic of the Umberto I Hospital, Sapienza University, in Rome, Italy, by researchers, through the google forms platform; qualitative variables were generated on excel sheets and a statistical analysis was performed on SPSS Ibm-statistics using the chi-square test. Results: Two hundred twenty-eight parents of children under 18 years of age completed the questionnaire (82% mothers, 18% fathers); 98% of the respondents used social media and 75% of them published their children's related content online. Thirty-one percent of the compilers started their practice of sharenting in the first 6 months of life of their child. Our analysis showed that compared to parents who do not post online, parents who usually post online their children are significantly more likely to be partial employees or unemployed (p = 0,002), with lower educational level (p = 0,05), younger (less than 35 years of age (p = 0,01)) and have a higher number of followers (p < 0,001). Finally, 93% of the compilers were not aware of the current legislation and of the risks related to the practice of sharenting. Conclusions: Pediatricians, healthcare assistants and preventive healthcare professionals should play a central role in alerting parents and families to the risks of sharenting; the results of our study could draw their attention to the increasing practice of sharenting and make healthcare professionals active part in the protection of children.

SARS‐CoV‐2 typically causes mild symptoms in children, but evidence suggests that persistent immunopathological changes may lead to long COVID (LC). To explore the interplay between LC and innate immunity, we assessed the type I interferon (IFN‐I) response in children and adolescents with LC symptoms (LC; n = 28). This was compared with age‐matched SARS‐CoV‐2 recovered participants without LC symptoms (MC; n = 28) and healthy controls (HC; n = 18). We measured the mRNA expression of IFN‐I (IFN‐α/β/ε/ω), IFN‐I receptor (IFNAR1/2), and ISGs (ISG15, ISG56, MxA, IFI27, BST2, LY6E, OAS1, OAS2, OAS3, and MDA5) in PBMCs collected 3–6 months after COVID‐19. LC adolescents (12–17 years) had higher transcript levels of IFN‐β, IFN‐ε, and IFN‐ω than HC, whereas LC children (6–11 years) had lower levels than HC. In adolescents, increased levels of IFN‐α, IFN‐β, and IFN‐ω mRNAs were found in the LC group compared with MC, while lower levels were observed in LC children than MC. Adolescents with neurological symptoms had higher IFN‐α/β mRNA levels than MC. LC and MC participants showed decreased expression of ISGs and IFNAR1, but increased expression of IFNAR2, than HC. Our results show age‐related changes in the expression of transcripts involved in the IFN‐I signaling pathway in children and adolescents with LC. [ABSTRACT FROM AUTHOR]

The anti-COVID-19 intramuscular vaccination induces a strong systemic but a weak mucosal immune response in adults. Little is known about the mucosal immune response in children infected or vaccinated against SARS-CoV-2. We found that 28% of children had detectable salivary IgA against SARS-CoV-2 even before vaccination, suggesting that, in children, SARS-CoV-2 infection may be undiagnosed. After vaccination, only receptor-binding domain (RBD)--specific IgA1 significantly increased in the saliva. Conversely, infected children had significantly higher salivary RBD-IgA2 compared to IgA1, indicating that infection more than vaccination induces a specific mucosal immune response in children. Future efforts should focus on development of vaccine technologies that also activate mucosal immunity. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, lung ultrasound (LUS) was widely used to assess SARS-CoV-2 infection. To date, there are patients with persistence of symptoms after acute infection. Therefore, it may be useful to have an objective tool to follow these patients. The aim of our study was to evaluate the presence of LUS artifacts after SARS-CoV-2 infection in children and to analyze the associations between time elapsed since infection and symptomatology during acute infection. We conducted an observational study, enrolling 607 children infected with SARS-CoV-2 in the previous twelve months. All patients performed a LUS and medical history of demographic and clinical data. We observed irregular pleural lines in 27.5%, B-lines in 16.9%, and subpleural consolidations in 8.6% of the cases. These artifacts were more frequently observed in the lower lobe projections. We have observed that the frequency of artifacts decreases with increasing time since infection. In symptomatic patients during COVID infection, B-lines (p = 0.02) were more frequently found. In our sample, some children, even after months of acute infection, have ultrasound artifacts and showed an improvement with the passage of time from the acute episode. Our study provides additional evidence about LUS in children with previous COVID-19 as a support to follow these patients in the months following the infection. [ABSTRACT FROM AUTHOR]

Aim: We evaluated the long-term clinical status of pediatric patients after testing positive for COVID-19. We hypothesized that there are similar symptoms to those that have been described in adults and children and that pediatric patients with neurophysiologic symptoms still present 3-5 months after infection have psychological consequences that interfere with their adaptive functioning. Method: We recruited 322 COVID-19-positive pediatric patients, between 1.5 and 17 years old, from the outpatient clinic for COVID-19 follow-up. Neurological symptoms were analyzed at onset, after 1 month, and after 3-5 months. A psychological assessment with standardized questionnaires was also conducted to determine the impact of the disease. Results: At the onset of COVID-19, 60% of the total sample exhibited symptoms; this decreased after 1 month (20%) but stabilized 3-5 months after disease onset (22%). Prevailing long-COVID neurological symptoms were headache, fatigue, and anosmia. In the 1.5-5-year-old subgroup, internalizing problems emerged in 12% of patients. In the 6-18-year-old subgroup, anxiety and post-traumatic stress showed significant associations with neurological symptoms of long COVID. Conclusions: These data demonstrate that long COVID presents various broad-spectrum symptoms, including psychological and long-lasting cognitive issues. If not treated, these symptoms could significantly compromise the quality of life of children and adolescents. [ABSTRACT FROM AUTHOR]

Children generally develop a mild disease after SARS-CoV-2 infection whereas older adults are at risk of developing severe COVID-19. Recent transcriptomic analysis showed pre-activated innate immunity in children, resulting in a more effective anti-SARS-CoV-2 response upon infection. To further characterize age-related differences, we studied type I and III interferon (IFN) response in SARS-CoV-2 infected and non-infected individuals of different ages. Specifically, levels of expression of type I (IFN-a, -b, -e and -w), type III (IFNl1, -l2 and -l3) IFNs and of the IFN-stimulated genes, ISG15 and ISG56 were quantified in nasopharyngeal cells from diagnostic swabs. Basal transcription of type I/III IFN genes was highest among children and decreased with age. Among SARS-CoV-2-infected individuals, only IFN-e and -w levels were significantly higher in children and young adults whereas ISGs were overexpressed in infected adults. The occurrence of symptoms in children and the need for hospitalization in adults were associated to higher transcription of several IFN genes. Starting from a pre-activated transcription level, the expression of type I and III IFNs was not highly up-regulated in children upon SARS-CoV-2 infection; young adults activated IFNs' transcription at intermediate levels whereas older adults were characterized by higher ISGs and lower IFN-e and -w relative expression levels. Overall, our findings contribute to recognize components of a protective IFN response as a function of age, in the context of SARS-CoV-2 infection. [ABSTRACT FROM AUTHOR]

To date, the diagnosis of mediastinal teratoma and mediastinal masses relies on the use of chest X-ray and CT. Lung and thoracic ultrasound is becoming increasingly used in the diagnosis and follow-up of many lung and thoracic diseases. Here, we report the case of a mature cystic teratoma in which the performance of lung ultrasound allowed to speed up the diagnostic workup and to provide the indication for the execution of CT of the thorax allowing the diagnosis.

Background: Two sequelae of pediatric COVID-19 have been identified, the multisystem inflammatory syndrome in children (MIS-C) and the long COVID. Long COVID is much less precisely defined and includes all the persistent or new clinical manifestations evidenced in subjects previously infected by SARS-CoV-2 beyond the period of the acute infection and that cannot be explained by an alternative diagnosis. In this Intersociety Consensus, present knowledge on pediatric long COVID as well as how to identify and manage children with long COVID are discussed. Main findings: Although the true prevalence of long COVID in pediatrics is not exactly determined, it seems appropriate to recommend evaluating the presence of symptoms suggestive of long COVID near the end of the acute phase of the disease, between 4 and 12 weeks from this. Long COVID in children and adolescents should be suspected in presence of persistent headache and fatigue, sleep disturbance, difficulty in concentrating, abdominal pain, myalgia or arthralgia. Persistent chest pain, stomach pain, diarrhea, heart palpitations, and skin lesions should be considered as possible symptoms of long COVID. It is recommended that the primary care pediatrician visits all subjects with a suspected or a proven diagnosis of SARS-CoV-2 infection after 4 weeks to check for the presence of symptoms of previously unknown disease. In any case, a further check-up by the primary care pediatrician should be scheduled 3 months after the diagnosis of SARS-CoV-2 infection to confirm normality or to address emerging problems. The subjects who present symptoms of any organic problem must undergo a thorough evaluation of the same, with a possible request for clinical, laboratory and / or radiological in-depth analysis in case of need. Children and adolescents with clear symptoms of mental stress will need to be followed up by existing local services for problems of this type. Conclusions: Pediatric long COVID is a relevant problem that involve a considerable proportion of children and adolescents. Prognosis of these cases is generally good as in most of them symptoms disappear spontaneously. The few children with significant medical problems should be early identified after the acute phase of the infection and adequately managed to assure complete resolution. A relevant psychological support for all the children during COVID-19 pandemic must be organized by health authorities and government that have to treat this as a public health issue.

Background: Community‐acquired pneumonia (CAP) represents one of the most common infectious diseases among children. Diagnosis of CAP is mainly clinical. Chest X‐ray (CXR) remains the gold standard for the diagnosis in severe or controversial conditions. Recently, some authors have focused on the application of ultrasound in lung diseases but the role of lung ultrasound (LUS) in the diagnosis of CAP is still debated. We aimed to study the concordance between LUS and CXR in evaluating specific signs of CAP. As a secondary aim, we sought to determine the sensitivity and specificity of LUS in CAP diagnosis compared with CXR. Finally, we evaluated the role of LUS during the follow up. Methods: We enrolled 68 children (<16 years old) hospitalized from October 2018 to September 2019 with a clinical and radiological diagnosis of CAP (cases: N = 41), or with no respiratory diseases (controls: N = 27), in whom a CXR was performed for clinical indications. All the children underwent LUS during hospitalization. The average time needed to perform LUS was 5–10 min for each child, and 19/41 cases were re‐evaluated by LUS and CXR 30 days after discharge. Results: Lung ultrasound confirmed CAP diagnosis in 40/41 patients. Concordance between the two techniques was K = 0.88 for the right lung and K = 0.70 for the left lung. Lung ultrasound showed a sensitivity of 97% and a specificity of 96% compared with CXR. At the follow up, sensitivity increased to 100% while specificity was 94%. Conclusions: Our study showed a potential benefit of LUS compared with CXR in the diagnosis and the follow up of CAP. [ABSTRACT FROM AUTHOR]

Severe Acute Respiratory Syndrome - Coronavirus - 2 (SARS-CoV-2) and its related Coronavirus Disease - 19 (COVID-19) has become a health emergency worldwide. The medical community has been concerned since the beginning of the outbreak about the potential impact of COVID-19 in children, especially in those with underlying chronic diseases. Fortunately, COVID-19 has been reported to be less severe in children than in adults. However, epidemiologic and clinical data are scarce. Children show unique features of SARS-CoV-2 involvement that may account for the low rate of infection and death in this age group. The purpose of this review is to summarize the most relevant evidence of COVID-19 in children highlighting similarities and differences with adults. [ABSTRACT FROM AUTHOR]

OBJECTIVES: We describe the way we treated 7 children with critical long-term complications after metallic balloon-expandable stenting in the left mainstem bronchus. METHODS: Endoscopic follow-up included a first bronchoscopy 3 weeks after stenting, then monthly for 3 months, every 4-6 months up to 1 year and at scheduled times to calibrate stent diameter up to final calibration. When major complications occurred, patients underwent chest computed tomographic angiography. RESULTS: In 1 of the 7 children (median age 2.8 years), metallic left bronchial stenting served as a bridge to surgery. After a median 4-year follow-up, all 7 children experienced recurrent stent ovalizations with stent breakage in 3 and erosion in 1. In 4 children, computed tomographic angiography showed abundant peribronchial fibrous tissue, in 2 left mediastinal rotation and in 1 displacement along the left bronchus after pulmonary re-expansion as the cause of stent-related complication. Of the 7 children, 6 underwent surgery (5 posterior aortopexy and 1 section of the ligamentum arteriosus) and 3 required nitinol stents placement within the metallic ones. One patient completed the follow-up, and 1 patient was lost to follow-up. All 5 remaining children still have permanent bronchial stents in place, patent and re-epithelialized after a median 10.5-year follow-up. There were no deaths. CONCLUSIONS: Satisfactory anatomical relationships when children have stents placed in the left mainstem bronchus alone do not guarantee the final success. Several mechanisms intervene to cause critical stent-related complications in children during growth. Permanent metallic stents should be used carefully, and only in selected patients.

Background: This crossover, randomized, double-blind study (conducted over a 32-week period) was performed to determine, in clinically stable Cystic fibrosis (CF) preschool children: the effects of 7% inhaled hypertonic saline on spirometry and interrupter resistance technique (Rint), and the possible side effects. Methods: Twelve CF children (6M, mean age ± SD: 5.7 ± 0.8 yrs) were enrolled and randomly assigned to receive hypertonic saline (HS-4 ml 7% sodium chloride), or normal saline (NS-0.9% sodium chloride) twice a day. After a 16 weeks period, therapy was exchanged to allow all the patients enrolled in the study to carry out both treatments. Monitoring visits, spirometry (COSMED Quark PFT4 ergo) and Rint were scheduled at 0,4,16,20,32 weeks. At T0, spirometric measurements and Rint were performed immediately before and 30 min after the inhalation therapy. Salbutamol (400 mcg) was administered before the drug at each visit. Results: After a 16-weeks treatment with HS an improvement of FVC (p = 0.02) and a favorable trend of FEV1 were registered. A worsening of FEV1 (p < 0.0001) and of FEF25-75 (p = 0.019) were found in NS group. No differences were found in expiratory and inspiratory Rint in both groups. No serious adverse events occurred. Conclusions: Seven percent hypertonic saline therapy proved to be a useful and safe treatment in young CF children with clinically stable conditions. Trial registration: ISRCTN12345678.

OBJECTIVES: Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS: Among 257 children evaluated for tracheobronchial vascular compression, we reviewed the clinical charts for the 59 patients (23%) who underwent surgery. After surgery, children in whom severe malacia and respiratory symptoms persisted underwent airway stenting. RESULTS: Among the 59 patients (boys: 58.1%, median age: 6.4 months, age range: 0.1-182.8 months), 79.7% had major comorbidities, 39% additional upper airway anomalies and 15.2% abnormal bronchial anatomy. Diagnostic imaging identified seven vascular anomalies: innominate artery compression 27.1%, left bronchial compression from the descending aorta and left pulmonary artery 20.3%, lesions associated with right aortic arch 22.0%, double aortic arch 13.6%, bovine arch type 10.2%, aberrant right subclavian artery 5.1% and pulmonary artery sling 1.7%. For severe residual malacia and severe persistent respiratory symptoms, 20 patients (33.9%) had silicone or metallic stents inserted. The most frequent indication for stenting was double aortic arch (P = 0.02 by chi-square test). A clinical prognostic factor for permanent stenting was left bronchial compression from the descending aorta and left pulmonary artery [odds ratio (OR): 14.667, 95% confidence interval (CI): 2.881-74.659], particularly if associated with congenital heart disease (OR: 30.00, 95% CI: 4.349- 206.927). All silicone stents but one were successfully removed; metallic uncovered stents were patent and completely re-epithelialized. CONCLUSIONS: When surgery leaves severe airway obstruction and respiratory symptoms unchanged, children with tracheobronchial malacia can safely undergo airway stenting. [ABSTRACT FROM AUTHOR]

Endoscopy represents the gold standard for the diagnosis of Helicobacter pylori infection. We evaluated three noninvasive tests in a group of children: the immunoassay for detection of H. pylori stool antigen, the polimerase chain reaction for identification of bacterial DNA on the oral cavity and the serum specific antibodies. One hundred and ninety children underwent endoscopy for various gastrointestinal symptoms. H. pylori stool antigen and anti- H. pylori antibodies were assayed by commercial kits. The bacterial DNA on saliva and oral plaque was detected by a seminested PCR. Based on the positivity of culture or urease rapid test and histology, infection was detected in 47 patients. The statistical analysis showed that, for the detection of the infection, stool antigen assay is more effective in sensitivity and negative predictive value (91.5% and 96.5%), whereas specificity and positive predictive values appear slightly better in serology (89.6% and 76.0%). Correlations between serum IgG both with patients’ age ( r = 0.21, p < .05) and H. pylori stool antigen ( r = 0.47, p < .01) were found. The search for bacterial DNA on oral samples proved to be very specific (99.1% on saliva and 98.2% on plaque), but insensitive (22.2% and 25.7%). In children H. pylori stool antigen represents a sensitive test, suitable for detecting H. pylori infection. Serum IgG proved to be more specific; the PCR on the oral cavity resulted as being a very specific, but insensitive test. [ABSTRACT FROM AUTHOR]

Lung ultrasound has become increasingly used in both adult and pediatric populations, allowing the rapid evaluation of many lung and pleura diseases. This popularity is due to several advantages of the method such as the low cost, rapidity, lack of ionizing radiation, availability of bedside and repeatability of the method. These features are even more important after the outbreak of the SARS-CoV-2 pandemic, given the possibility of recognizing through ultrasound the signs of interstitial lung syndrome typical of pneumonia caused by the virus. The purpose of this paper is to review the available evidence of lung ultrasound (LUS) in children and its main applications in pediatric diseases. [ABSTRACT FROM AUTHOR]
