In pediatric practice, POCUS (point-of-care ultrasound) has been mostly implemented to recognize lung conditions and pleural and pericardial effusions, but less to evaluate fluid depletion. The main aim of this review is to analyze the current literature on the assessment of dehydration in pediatric patients by using POCUS. The size of the inferior vena cava (IVC) and its change in diameter in response to respiration have been investigated as a tool to screen for hypovolemia. A dilated IVC with decreased collapsibility (< 50%) is a sign of increased right atrial pressure. On the contrary, a collapsed IVC may be indicative of hypovolemia. The IVC collapsibility index (cIVC) reflects the decrease in the diameter upon inspiration. Altogether the IVC diameter and collapsibility index can be easily determined, but their role in children has not been fully demonstrated, and an estimation of volume status solely by assessing the IVC should thus be interpreted with caution. The inferior vena cava/abdominal aorta (IVC/AO) ratio may be a suitable parameter to assess the volume status in pediatric patients even though there is a need to define age-based thresholds. A combination of vascular, lung, and cardiac POCUS could be a valuable supplementary tool in the assessment of dehydration in several clinical scenarios, enabling rapid identification of life-threatening primary etiologies and helping physicians avoid inappropriate therapeutic interventions.   Conclusion: POCUS can provide important information in the assessment of intravascular fluid status in emergency scenarios, but measurements may be confounded by a number of other clinical variables. The inclusion of lung and cardiac views may assist in better understanding the patient's physiology and etiology regarding volume status. What is Known: • In pediatric practice, POCUS (point-of-care ultrasound) has been mostly implemented to recognize lung conditions (like pneumonia and bronchiolitis) and pleural and pericardial effusions, but less to evaluate fluid depletion. • The size of the IVC (inferior vena cava) and its change in diameter in response to respiration have been studied as a possible screening tool to assess the volume status, predict fluid responsiveness, and assess potential intolerance to fluid loading. What is New: • The IVC diameter and collapsibility index can be easily assessed, but their role in predicting dehydration in pediatric age has not been fully demonstrated, and an estimation of volume status only by assessing the IVC should be interpreted carefully. • The IVC /AO(inferior vena cava/abdominal aorta) ratio may be a suitable parameter to assess the volume status in pediatric patients even though there is a need to define age-based thresholds. A combination of vascular, lung, and cardiac POCUS can be a valuable supplementary tool in the assessment of intravascular volume in several clinical scenarios., (© 2023.

Background: Atraumatic limping is a frequent cause of consultation in Pediatric Emergency Departments (PED) and often represents a challenge for pediatricians for its variability in etiology ranging from benign causes to potential crippling conditions. The aims of this research are to illustrate the clinical features of acute limping children (LC) and to identify the possible red flags that could help to make a diagnosis of severe pathologies., Methods: We carried out a retrospective study about non-traumatic limping children referred to the PED of Bambino Gesù Children's Hospital over a 2-year period. We divided the cohort into three groups based on the patient's age: toddlers, children and adolescents. We considered crippling conditions: oncologic etiologies, bone or neurological infections, epiphysiolysis, Perthes disease, Guillain Barrè syndrome and non-accidental injuries., Results: We analyzed 485 patients. At clinical evaluation, 19.5% of the patients presented at least one sign and/or symptom of red flags. Crippling conditions (6.2% of the total population) showed red flags in 36.7%. Transient synovitis of the hip was the most frequent diagnosis. We found crippling conditions in 30 patients, mostly represented by toddlers., Conclusions: Our data suggest that toddlers and patients presenting red flags should be evaluated with particular suspicion because they have an increased risk of underlying severe conditions.

Background: Aggregatibacter actinomycetemcomitans (Aa), previously known as Actinobacillus actinomycetemcomitans, is a slow-growing Gram-negative coccobacillus, member of the HACEK group of bacteria colonizing oral flora. Besides causing infectious diseases in the oral cavity such as dental caries and periodontitis, it is responsible for severe extra-oral infections secondary to hematogenous spread or aspiration, such as endocarditis, soft tissue abscesses and osteomyelitis. The diagnosis depends on prolonged bacterial culture of biological material obtained through biopsy. Aa is susceptible to most antibiotics but complete eradication often requires a long term treatment., Case Presentation: We report the case of a 15-year-old previously healthy boy diagnosed with both pulmonary empyema and subphrenic chest wall abscess caused by Aa. He was admitted to our Pediatric Emergency department for evaluation of a right mass associated with marked asthenia and dry cough. After radiological findings etiological diagnosis was made by culture of fluid drainage of pleural empyema. He started empirical antibiotic therapy with intravenous piperacillin/tazobactam, whose sensibility was confirmed by the antibiogram, then, for occurrance of hepatopathy it was switched to ciprofloxacin: the patient almost completely recovered after 6-month therapy., Conclusions: Extra-oral infections caused by Aa are extremely rare, especially in children, and not well described yet. To our knowledge, there is only another similar case described in literature. However, the case described in our manuscript represents the only one presenting with pulmonary empyema without involvement of lung parenchyma in children. We also conducted a brief review of published cases of Aa infection in the pediatric population. This case report reminds us the importance of an accurate inspection of the oral cavity during the examination of pediatric patients., (© 2023. The Author(s).)

Background: Intercepting earlier suspected TB (Tuberculosis) cases clinically is necessary to reduce TB incidence, so we described signs and symptoms of retrospective cases of pulmonary TB and tried to evaluate which could be early warning signs., Methods: We conducted a retrospective descriptive study of pulmonary TB cases in children in years 2005-2017; in years 2018-2020 we conducted a cohort prospective study enrolling patients < 18 years accessed to Emergency Department (ED) with signs/symptoms suggestive of pulmonary TB., Results: In the retrospective analysis, 226 patients with pulmonary TB were studied. The most frequently described items were contact history (53.5%) and having parents from countries at risk (60.2%). Cough was referred in 49.5% of patients at onset, fever in 46%; these symptoms were persistent (lasting ≥ 10 days) in about 20%. Lymphadenopathy is described in 15.9%. The prospective study enrolled 85 patients of whom 14 (16.5%) were confirmed to be TB patients and 71 (83.5%) were non-TB cases. Lymphadenopathy and contact history were the most correlated variables. Fever and cough lasting ≥ 10 days were less frequently described in TB cases compared to non-TB patients (p < 0.05)., Conclusions: In low TB endemic countries, pulmonary TB at onset is characterized by different symptoms, i.e. persistent fever and cough are less described, while more relevant are contact history and lymphadenopathy. It was not possible to create a score because signs/symptoms usually suggestive of pulmonary TB (considered in the questionnaire) were not significant risk factors in our reality, a low TB country., (© 2022.

During the COVID-19 pandemic, the lung ultrasound (LU) turned out to be a pivotal tool to study the lung involvement in the adult population, but the same was not well evaluated in children. We detected the LU patterns through an integrated approach with clinical−laboratory features in children hospitalized for COVID-19 in relation to the temporal trend of the Italian epidemic. We conducted a retrospective study which took place at a pediatric tertiary hospital from 15 March 2020 to 15 March 2021. We compared the characteristics of the initial phase of the first COVID-19 year—in the spring and summer (15 March−30 September 2020)—and those of the second phase—in the autumn and winter (1 October 2020−15 March 2021). Twenty-eight patients were studied both in the first and in the second phase of the first COVID-19 year. The disease severity score (DSS) was significantly greater in the second phase (p = 0.015). In the second phase of the first COVID-19 year, we detected a more significant occurrence of the following LU features than in the first phase: the irregular pleural line (85.71% vs. 60.71%; p = 0.035), the B-lines (89.29% vs. 60%; p = 0.003) and the several but non-coalescent B-lines (89.29% vs. 60%; p = 0.003). The LU score correlated significantly with the DSS, with a moderate relationship (r = 0.51, p < 0.001). The combined clinical, laboratory and ultrasound approaches might be essential in the evaluation of pulmonary involvement in children affected by COVID-19 during different periods of the pandemic.

Introduction: Understanding how the use of hoverboards (HBs) can affect a child's safety is crucial. We describe the characteristics of HB related injuries and provide key messages about child prevention when using these leisure devices., Methods: This was a retrospective study at an emergency department (ED) of a level-III-trauma center from 2016 to 2019. We tested the differences in children presenting for injury associated with HBs between 2016-2017 and 2018-2019 to better describe the temporal trend of the phenomenon., Results: The rate of Injury associated with HBs / Total injury per 1,000 increased from 0.84 in 2016 to 7.7 in 2017, and then there was a gradual decline. The likelihood of injury was more common in younger children, increasing by 17% with decreasing age in 2018-2019 compared with 2016-2017 (OR: 0.83; 95%CI: 0.71-0.97; p = 0.021). The occurrence of injury in the April-June period was over twice as common in 2018-2019 (OR: 2.05; 95%CI: 1.0-2.05; p = 0.05). Patients were over 4 times more likely to have injured the lower extremity during the 2018-2019 period rather than other body regions (OR: 4.58; 95%CI: 1.23-4.58; p = 0.02). The odds of the indoor injury were more than twice as high in 2018-2019 (OR: 2.04; 95%CI: 1.077-2.04; p = 0.03)., Conclusion: Despite a decrease in the frequency of HB related injuries after 2017, during the 2018-2019 period, the younger the children, the more they were exposed to injury risk, in addition to a greater occurrence of indoor injuries from HBs compared with 2016-2017. The enhancement of preventive measures is necessary to ensure child safety when using HBs., (© 2022. The Author(s).)

Objectives: The soft scalp hematoma is one of the clinical markers used as a predictor for the presence of intracranial injury in children with a head trauma. We evaluated the significance of time presentation in the management of these patients., Methods: We conducted a retrospective study of children and adolescents aged 0 to <18 years by comparing the clinical, radiological, and epidemiological features in those presenting within 24 hours with those presenting greater than 24 hours after a head injury., Results: We identified 188 and 98 patients with early presentation and late presentation, respectively. The percentage of children aged 0 to <6 months was lower in those with late presentation (6.12%) than those with early presentation (20.21%) with a significant difference (P < .001). Likewise, the percentage of children aged ≥24 months was lower in children with late presentation (7.14%) than those with early presentation (34.04%) with a significant difference (P < .001). The severe mechanism rate was more elevated in early presentation (38.83%) with a significant difference (-14.34%; 95% confidence interval [CI], -25.34% to -3.34%; P = .015). The symptom rate resulted higher in early presentation (14.36%) with a significant difference (-11.30%; 95% CI, -17.36% to 5.22%; P = .003). The parietal scalp hematoma occurred mostly in children with late presentation (85.71%) with a significant difference (19.76%; 95% CI, 10.07% to 29.45%; P < .001). The occipital scalp hematoma rate was higher in early presentation with a significant difference (-17.50%; 95% CI, -22.99% to -12.12%; P < .001). There was no significant difference in the prevalence of different types of intracranial injury, and the only 5 patients needing a neurosurgical intervention were exclusively children with an early presentation., Conclusion: Although children with soft scalp hematoma presenting to the emergency department greater than 24 hours after a head injury may have pathological findings on computed tomography, all of them had a good short- and long-term outcomes, and no neurological deterioration aroused the medical attention on follow-up. For this subset of patients that does not experience red flags (neurological symptoms, focal signs on examination, or severe injury mechanism), a wait-and-see approach might be more appropriate rather than neuroimaging., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Spontaneous pneumothorax is a relatively uncommon and poorly studied condition in children. While several protocols have been developed to evaluate the use of lung ultrasound for dyspneic adult patients in the emergency department, no specific guidelines are present for pediatric emergency physicians., Objectives: We prospectively analyzed children with acute chest pain and clinical suspicion of pneumothorax evaluated at the pediatric emergency department., Methods: We consecutively enrolled children aged 5-17 years presenting to the pediatric emergency department with clinically suspected pneumothorax based on sudden onset of acute chest pain. After clinical examination, all children underwent lung ultrasound followed by chest X-ray (reference standard). We enrolled 77 children, of which 13 (16.9%) received a final diagnosis of pneumothorax., Results: The lung point had a sensitivity of 92.3% (95% CI 77.8-100) and a specificity of 100% (95% CI 94.4-100) for the detection of pneumothorax. The "barcode sign" had a sensitivity of 100% (95% CI 75.3-100) and a specificity of 100% (95% CI 94.4-100) for the detection of pneumothorax., Conclusion: Lung ultrasound is highly accurate in detecting or excluding pneumothorax in children with acute chest pain evaluated in the pediatric emergency department. If pneumothorax is suspected, but the lung point is not visible, the barcode sign should always be sought as it could be a form of massive pneumothorax., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Lung diseases are the most common conditions in newborns, infants, and children and are also the primary cause of death in children younger than 5 years old. Traditionally, the lung was not thought to be a target for an ultrasound due to its inability to penetrate the gas-filled anatomical structures. With the deepening of knowledge on ultrasound in recent years, it is now known that the affected lung produces ultrasound artifacts resulting from the abnormal tissue/gas/tissue interface when ultrasound sound waves penetrate lung tissue. Over the years, the application of lung ultrasound (LUS) has changed and its main indications in the pediatric population have expanded. This review analyzed the studies on lung ultrasound in pediatrics, published from 2010 to 2020, with the aim of highlighting the usefulness of LUS in pediatrics. It also described the normal and abnormal appearances of the pediatric lung on ultrasound as well as the benefits, limitations, and possible future challenges of this modality., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Musolino, Tomà, De Rose, Pitaro, Boccuzzi, De Santis, Morello, Supino, Villani, Valentini and Buonsenso.)

Background: To date, there are no data regarding the systematic application of Point-of-Care Lung Ultrasound (PoC-LUS) in children with Multisystem Inflammatory Syndrome in Children (MIS-C). The main aim of this study is to show the role of Point-of-Care Lung Ultrasound as an additional aid in the diagnosis of COVID-19-related Multisystem Inflammatory Syndrome in Children (MIS-C)., Methods: Between April 2020 and April 2021, patients aged 0-18 years referred to our emergency department for fever, and later hospitalized without a specific diagnosis, underwent PoC-LUS. Ultrasound images of patients with a final diagnosis of MIS-C were retrospectively evaluated., Results: Ten patients were enrolled. All were described to have pleural irregularities and B-lines. In particular: 8/10 children presented with isolated B-lines in at least half of the lung areas of interest; 8/10 presented with multiple B-lines and 3/8 had them in at least 50% of lung areas; 5/10 had a white lung appearance in at least one lung area and 1/5 had them in half of the areas of interest. Pleural effusion was described in 9/10., Conclusions: During the ongoing COVID-19 pandemic, we suggest performing PoC-LUS in febrile patients with high levels of inflammatory indices and clinical suspicion of MIS-C, or without a certain diagnosis; the finding of many B-lines and pleural effusion would support the diagnosis of a systemic inflammatory disease.

Abstract: Leukemia is the most common childhood malignancy, and it is often characterized by pallor, fatigue, cytopenia, and organomegaly; sometimes musculoskeletal symptoms, mainly characterized by diffuse bone pain in the lower extremities, are the onset clinical characteristics of the disease. In these cases, the disease may initially be misdiagnosed as reactive arthritis, osteomyelitis, or juvenile idiopathic arthritis delaying appropriate diagnosis and management. Even if leukopenia, thrombocytopenia, and a history of nighttime pain are reported to be the most important predictive factors for a pediatric leukemia, blood examinations can sometimes be subtle or within normal limits, and this represents a further diagnostic difficulty. Radiological findings of leukemic bone involvement are described in patients with musculoskeletal symptoms of acute lymphoblastic leukemia and often appear before hematologic anomalies, but they are not specific for the disease. However, they could be helpful to get the right diagnosis if integrated with other features; thus, it is important knowing them, and it is mandatory for the multidisciplinary comparison to talk about dubious cases even in an emergency setting. We describe 4 patients visited in the emergency department for musculoskeletal complaints and having radiological lesions and a final diagnosis of acute lymphoblastic leukemia, in whom the onset of the manifestations could mimic orthopedic/rheumatologic diseases., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2018 Wolters Kluwer Health, Inc.

Point-of-care lung ultrasound is a widely used tool in the diagnosis and management of patients with pulmonary diseases and now with SARS-CoV-2 infection. We describe two cases of pneumothorax which are, as far as we know, among the first reported in COVID-19 patients younger than 18 years. The diagnostic and monitoring role of point-of-care lung ultrasound has been extremely useful in the management of patients., (© 2021 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Point-of-care ultrasound (POCUS) is a growing interesting tool in the emergency setting. Its usefulness in diagnostic and therapeutic pathway of patients with respiratory distress in addition to clinical evaluation is well established in adult emergency medicine while paediatric specific data, although growing, remain limited. We report a case series of paediatric patients presenting with respiratory distress successfully diagnosed with cardiac dysfunction following POCUS evaluations. Lung POCUS, in combination with cardiac POCUS, is a very useful supplementary diagnostic tool to assess the breathless child and to rapidly identify life-threatening primary etiologies or secondary physiologies. Thus, fast echocardiography is a desirable aid for paediatric emergency physicians and should be supported in all paediatric emergency settings following an adequate training that is mandatory regarding image acquisition and data interpretation., (© 2020 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Background: The role of multiple respiratory viruses in bronchiolitis treated with high-flow nasal cannula (HFNC) has not been thoroughly investigated. We evaluated the contribution of coinfection on clinical course of bronchiolitis treated with HFNC and on response to this treatment., Methods: We selected 120 children with bronchiolitis, younger than 12 months, admitted to Emergency Department between 2016 and 2018 and treated with HFNC. We compared single and multiple virus infections in relation to specific outcomes such as the clinical response to HFNC and the HFNC failure. The multiple virus infection was defined by the detection of 2 or more viruses in nasopharyngeal aspirates. The HFNC failure was defined as escalation to higher level of care, including Helmet-Continuous Positive Airway Pressure, invasive ventilation or transfer to pediatric intensive care unit within 48 hours from the time of HFNC initiation. We also performed a comparison between HFNC failure and HFNC not-failure groups according to the number of virus and the type of virus., Results: The severity score post-HFNC initiation was significantly associated with coinfection [odds ratio (OR): 1.361; 95% confidence interval (CI): 1.036-1.786; P = 0.027]. The likelihood of coinfection decreased by 23.1% for each increase of saturation O2 after HFNC initiation (OR: 0.769; 95% CI: 0.609-0.972; P = 0.028). Atelectasis was more likely to occur in coinfection (OR: 2.923; 95% CI: 1.049-8.148; P = 0.04). The duration of HFNC treatment increased significantly in coinfection (OR: 1.018; 95% CI: 1.006-1.029; P = 0.002). No significant differences were described between HFNC failure and the number and the type of detected viruses., Conclusions: The detection of multiple viruses and the type of virus did not influence the HFNC failure, although the coinfection was associated with a deterioration of severity score, a longer HFNC treatment and a major presence of atelectasis. The role of coinfection on HFNC treatment might subtend a complex interplay between multiple viruses and host susceptibility.

Objectives: The study aimed to evaluate the emergency department (ED) presentation of children with a diagnosis of osteomyelitis, septic arthritis, or both., Methods: A retrospective single-center study was conducted on all children aged between 1 month and 18 years evaluated in the ED over a 7-year period and having a final diagnosis of osteoarticular infection. One hundred seventeen patients were enrolled., Results: Only 39.3% of patients were admitted after the first evaluation, and only 45.3% had a proper diagnosis of admission. Pain was the only symptom reported by all. White cell count, C-reactive protein level, and erythrocytes sedimentation rate were normal in 49.5%, 21.4%, and 17.1% of children, respectively. X-ray findings were unremarkable in 48% of cases. Clinical and bone structural sequelae were described in 19.23% and 56.86% of all cases. No statistically significant differences were found among osteomyelitis, arthritis, and the combination of both regarding all considered variables, except for structural outcomes resulting more significant in the third group. Significant differences were evident in clinical manifestations, blood examinations, and findings of osteolysis between patients diagnosed within and after 1 week since the disease onset. Finally, questionable differences between white blood cells and C-reactive protein level were found among patients younger than 5 years and older ones, whereas a history of trauma was more often reported in the second group., Conclusions: The difficulty in recognizing osteoarticular infection in a pediatric ED can be due to the possible lack of the classic signs and symptoms, and the absence of specific laboratory and radiologic findings.

Mild encephalopathy with a reversible splenial lesion (MERS) is an uncommon clinico-radiological entity characterized by magnetic resonance imaging (MRI) findings of a reversible lesion in the splenium of corpus callosum associated with a significant neurological manifestation of encephalopathy. The majority of reported cases involve the Asiatic population and are closely associated with infection. We report the case of an adolescent with an HHV6-related MERS presenting with hyponatremia and urinary and fecal retention. To our knowledge, urinary retention is not a constant aspect of the disease and has rarely been described, while fecal retention has never been reported before. Despite the self-limiting nature of the disease, it is mandatory to suspect it for a faster diagnosis and it might be useful to know its rare occurrences in order to better understand its etiopathogenetic mechanisms.

This retrospective study was conducted to analyze clinical and laboratoristic parameters to individuate specific differences and facilitate differential diagnosis between Measles and Kawasaki Disease (KD) at first evaluation in an emergency room. We found similar clinical features as duration of fever and number of KD criteria (p > 0.5) but significant differences in white blood cell count, neutrophils, CRP and LDH levels (p < 0.001). LDH value ≥ 800 mg/dl had sensibility of 89% and specificity of 90% for Measles while CRP ≥ 3 mg/dl had sensibility 89% and specificity of 85% for KD. The combined use of CRP, LDH and AST showed accuracy of 86.67%., Competing Interests: Competing interests: The authors have declared that no competing interests exist.

The occurrence of hospital-acquired acute gastroenteritis (AGE) is a major concern for public health. RotavirusA (RVA) and norovirus (NoV) are common causes of viral AGE in the pediatric population, and their role in nosocomial infections has been proven, remaining poorly investigated. To investigate RVA and NoV in hospital-acquired AGE, 55 stool samples from children with nosocomial AGE were collected between May 2014 and May 2015. To evaluate virus spreading routes, 51 environmental swabs were collected from staff and patients' rooms. Stools were tested for both RVA and NoV RNA by reverse-transcription-PCR. Nucleotide sequencing and phylogenetic analysis were performed to characterize the viruses. Forty-seven of 55 cases analyzed resulted positive for RVA. The predominant genotype was G4P[8] (18/55) followed by G1P[8] (14/55). Mixed RVA infections were also detected (7/55). Twenty-two samples were positive for NoV, and GII.4 was revealed to be the predominant genotype. Seventeen samples were positive for both RVA and NoV. This study aimed to evaluate the burden of norovirus and rotavirus nosocomial AGE, contributing to identify the environment source of infections and to activate effective strategies for intervention. The reduction in nosocomial AGE cases is an important aspect, considered the worsened disease course in transplant, cancer, and intensive care unit inpatients., (© 2017 Wiley Periodicals, Inc.)

Background: Acute cerebellitis (AC) and acute cerebellar ataxia (ACA) are the principal causes of acute cerebellar dysfunction in childhood. Nevertheless. there is no accepted consensus regarding the best management of children with AC/ACA: the aim of the study is both to assess clinical, neuroimaging and electrophysiologic features of children with AC/ACA and to evaluate the correlation between clinical parameters, therapy and outcome., Methods: A multicentric retrospective study was conducted on children ≤ 18 years old admitted to 12 Italian paediatric hospitals for AC/ACA from 01/01/2003 to 31/12/2013. A score based on both cerebellar and extracerebellar signs/symptoms was computed for each patient. One point was given for each sign/symptom reported. Severity was divided in three classes: low, moderate, severe., Results: A total of 124 children were included in the study. Of these, 118 children received a final diagnosis of ACA and 6 of AC. The most characteristic finding of AC/ACA was a broad-based gait disturbance. Other common symptoms included balance disturbances, slurred speech, vomiting, headache and fever. Neurological sequelae were reported in 6 cases (5%) There was no correlation among symptoms, cerebrospinal fluid findings, clinical outcome. There was no correlation between clinical manifestations and clinical score on admission and length of hospital stay, sex, age and EEG findings with sequelae (P > 0.05). Children with pathological magnetic resonance imaging (MRI) or computed tomography (CT) had a higher probability of having clinical sequelae. Treatment was decided independently case by case. Patients with a higher clinical score on admission had a higher probability of receiving intravenous steroids., Conclusions: We confirmed the literature data about the benign course of AC/ACA in most cases but we also highlighted a considerable rate of patients with neurological sequelae (5%). Pathological MRI or CT findings at admission correlate to neurological sequelae. These findings suggest the indication to perform an instrumental evaluation in all patients with AC/ACA at admission to identify those at higher risk of neurological outcome. These patients may benefit from a more aggressive therapeutic strategy and should have a closer follow-up. Randomized controlled trials are needed to confirm these observations. The ultimate goal of these studies could be to develop a standardized protocol on AC/ACA. The MRI/CT data, associated with the clinical manifestations, may allow us to define the class risk of patients for a neurological outcome.

Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries.

Background: Anorexia Nervosa is a Psychiatric eating disorder of adolescence age with a high morbidity and mortality., Case Presentation: We describe a common case of anorexia nervosa (AN) in a female adolescent complicated by less known conditions related to refeeding syndrome. At admission, the girl showed a mild hypercholesterolemia with progressive normalization of the values. The initial low hypertransaminasemia worsened after refeeding until very high levels and hypophosphoremia was also described. Only a controlled caloric intake and a specific electrolyte supplementation led to the improvement of hematologic values and the clinical condition of the patient., Conclusions: Refeeding complications must be always suspected because of life-threatening risk. More attention should be paid not only to the acute state of the disease but also to the prevention and the management of refeeding-related manifestations.

We report the case of a two-month-old immunocompetent girl affected by Staphylococcus aureus sepsis complicated with pneumonia and pleural effusion, spondylodiscitis and endophthalmitis treated with linezolid. She developed a S. aureus sepsis in the neonatal period antibiotically treated with clinical resolution. Ten days after therapy discontinuation, the infant experienced a new S. aureus sepsis complicated by pneumonia with pleural effusion. Due to the presence of dorsal swelling, a pulmonary computer tomography was performed that showed a dorsal D5-D6 spondylodiscitis. Since the sepsis was scarcely responsive to several appropriate antibiotics, we finally decided to treat the patient with linezolid. A few weeks after changing antibiotics, the child underwent an ophthalmologic visit. Due to the finding of ocular lesions, imaging examinations were performed. The diagnosis was compatible with retinoblastoma, such that the eye was enucleated. Nevertheless, histological and microbiological investigations did not confirm the tumour hypothesis, but revealed a S. aureus abscess with retinal detachment. The child completed antibiotic therapy with linezolid and was visited periodically at the Infectious Disease Unit for a follow-up. She underwent progressive resolution of discitis and did not present any further flare of sepsis. Nevertheless, she still has a replacement device in her right eye and a D5-D6 severe kyphosis with spinal fusion.
