Multiple investigators have described an increased incidence of thromboembolic events in SARS-CoV-2-infected individuals. Data concerning hemostatic complications in children hospitalized for COVID-19/multisystem inflammatory syndrome in children (MIS-C) are scant.To share our experience in managing SARS-CoV-2-associated pro-coagulant state in hospitalized children.D-dimer values were recorded at diagnosis in children hospitalized for SARS-CoV-2-related manifestations. In moderately to critically ill patients and MIS-C cases, coagulation and inflammatory markers were checked at multiple time points and median results were compared. Pro-thrombotic risk factors were appraised for each child and thromboprophylaxis was started in selected cases.Thirty-five patients were prospectively enrolled. D-dimer values did not discriminate COVID-19 of differing severity, whereas were markedly different between the COVID-19 and the MIS-C cohorts. In both cohorts, D-dimer and C-reactive protein levels increased upon clinical worsening but were not accompanied by decreased fibrinogen or platelet values, with all parameters returning to normal upon disease resolution. Six patients had multiple thrombotic risk factors and were started on pharmacological thromboprophylaxis. No deaths or thrombotic or bleeding complications occurred.COVID-19 pediatric patients show mildly altered coagulation and inflammatory parameters; on the other hand, MIS-C cases showed laboratory signs of an inflammatory driven pro-coagulant status. Universal anticoagulant prophylaxis in hospitalized children with SARS-CoV-2-related manifestations is not warranted, but may be offered to patients with other pro-thrombotic risk factors in the context of a multi-modal therapeutic approach.

Little is known about the sequelae of SARS-CoV-2 infection in children. In a COVID-19 dedicated clinic, we followed-up for 4 months 25 children previously hospitalized for COVID-19, performing clinical, laboratory, and lung ultrasound evaluation. Mid-term sequelae were rarely observed in our COVID-19 children's cohort.

The rapid spread of the novel coronavirus (severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) in Italy forced a prompt hospital reorganisation in the past 2 months. Every clinic has been divided into two separate departments, based on the detection of SARS-CoV-2 in the nasopharyngeal swab.1 In children, three main variables complicate this: first, the not optimal sensitivity of nasopharyngeal swabs, mainly due to technical difficulties2; second, the need of a caregiver during the hospital stay; finally, the high number of paediatric diseases manifesting with fever or cough, thus sharing symptoms of COVID-19, which cause about 25% of emergency department (ED) admissions.3 All these elements make the paediatric testing strategy more challenging. We performed an observational study at Regina Margherita Children’s Hospital of Turin. Two cohorts of patients were collected: cohort A included all the children admitted to the ED from 2 March 2020 through 22 April 2020, with COVID-19-related symptoms; cohort B was composed of patients …

* Abbreviations: COVID-19 — : coronavirus disease 2019 LUS — : lung ultrasound The novel coronavirus disease 2019 (COVID-19) is rapidly spreading all around the world, affecting both adults and children. Recently, the clinical and radiographic characteristics of children infected have been described.1 Although lung ultrasound (LUS) is recognized as a valid imaging technique for the diagnosis and follow-up of pneumonia in pediatric age,2 no data are currently available about LUS use in children with COVID-19. Considering the well-known advantages of point-of-care ultrasound,3 including the possibility of reducing the patient’s movement across the hospital department, we investigated LUS findings in … Address correspondence to Marco Denina, MD, Paediatric Infectious Diseases Unit, Regina Margherita Children’s Hospital, University of Turin, Piazza Polonia 94, 10126 Turin, Italy.

Significant progress has been made in the diagnosis and treatment of syphilis since the identification of the causative agent, Treponema pallidum, in 1905. However, syphilis remains a major public health problem in many developing countries and there has been a recrudescence in developed countries during the last two decades [1].

Deep neck infection (DNI) is a severe occurrence in children. We've examined the presenting signs and symptoms, the value of single diagnostic procedures, the rate of complications and the impact of the therapeutic options on the final outcome, in children with a DNI. We retrospectively evaluated patients, aged 0–18 years, who were admitted for a DNI, from January 2006 through December 2012, at Regina Margherita Children's Hospital, Turin, Italy. We subdivided them on the basis of type of treatment: pharmacological treatment alone or antimicrobial treatment plus surgery. An univariate analysis has been performed to examine the differences between the two groups. Sixty patients (32 males, 28 females) with diagnosis of DNI were enrolled; 33 children only received medical treatment (group 1), whereas 27 patients underwent also surgical interventions (group 2). The mean abscess size was significantly higher in group 2 than in group 1 ( p = 0.01). The predominant organisms were Streptococcus sp. (11 cases, 52.4%, mostly Streptococcus pyogenes ). The most frequent antibiotic regimen was a β lactam alone (either III generation cephalosporin or amoxicillin/clavulanate). The duration of intravenous antibiotic varied between the two groups, without statistical significance ( p = 0.052); whereas the oral antibiotic administration was significantly shorter in group 1 than in group 2 ( p = 0.0003). Three patients (5%) developed complications. This research confirms that the medical approach, with high doses of intravenous antibiotics for a minimum of 5 days, could be a tolerable and safe option for the treatment of patients with stable condition and/or small DNIs.

SUMMARYDrug-resistant paediatric tuberculosis (TB) is an overlooked global problem. In Italy, the epidemiology of TB has recently changed and data regarding drug-resistant forms in the paediatric setting is scanty. The aim of this case series was to report the cases of drug-resistant TB, diagnosed between June 2006 and July 2010 in four Italian tertiary centres for paediatric infectious diseases, in children and adolescents living in Italy. Twenty-two children were enrolled, of these 17 were resistant to one or more drugs and five had multidrug-resistant TB. All but one child were either foreign born or had at least one foreign parent. Twenty-one patients completed their treatment without clinical or radiological signs of activity at the end of treatment, and one patient was lost to follow up. The outcomes were good, with few adverse effects using second-line anti-TB drugs. Although this series is limited, it might already reflect the worrisome increase of drug-resistant TB, even in childhood.

The natural history of vertically acquired HCV infection is ill defined. The aim of this study was to outline the natural course of vertical HCV infection in a cohort of untreated children, including rate of spontaneous viral clearance, frequency and features of HCV-related autoimmune disorders. Children with vertical HCV infection were prospectively followed from the first month of life with regular clinical and laboratory assessments. Statistical analysis was performed using Prism 5.0. Forty-five children (median age 12 years, interquartile range 6.9–15.5) were studied. Genotype 1 was predominant (53.3 %). Spontaneous viral clearance was achieved by 12 patients (26.7 %) and associated with genotype 3. Alanine-amino-transferase levels were increased in most children in the first 2 years of life with higher values in those who later cleared the infection. All children were asymptomatic for liver disease. Transient elastography (32 patients) showed mild or moderate fibrosis in nine and two cases, respectively. Non-organ-specific autoantibodies were detected in 24 children (53.3 %) independently of viremia; of these, one developed type-1 diabetes. Cryoglobulinemia was associated with genotype 1 infection and found in 15 subjects (33.3 %): two had low C4 levels and persistent proteinuria. Conclusions: Vertically acquired HCV infection may result in spontaneous clearance in up to 27 % of children. Resolution of infection is higher with genotype 3, usually occurs in preschool age and persists over time. Chronic infection is generally asymptomatic, although hepatomegaly and mild fibrosis may develop. Autoantibodies and cryoglobulins are frequent, whereas the associated clinical manifestations are rare.

We report here 2 pediatric cases of multidrug-resistant (MDR) tuberculosis (TB) that were observed in Italy. Both families came from an Eastern European country, which is notably an area with a high prevalence of MDR TB. An increase of new cases of MDR TB in developed countries is expected over the next years because of migratory flow, and specific measures and strategies need to be taken to prevent the propagation and dissemination of MDR TB. An efficacious treatment including linezolid and moxifloxacin was administered for 13 months in 1 case. No adverse reactions were detected during close child monitoring. Linezolid and newer fluoroquinolones such as moxifloxacin have been reported to be effective for MDR-TB treatment in adults. On the contrary, there is limited available evidence regarding the effectiveness and safety of these drugs in infants and children with MDR TB. The use of second-line drugs not approved for use in children may be necessary to treat a life-threatening disease such as MDR TB, but it requires careful monitoring to quickly recognize the occurrence of dose- and duration-dependent adverse drug reactions.

Neurocysticercosis represents an important cause of seizures in children in endemic countries, such as Latin America, Asia and sub-Saharan Africa, while in Europe, especially in Italy, the cases of neurocysticercosis are anectodal. We report the case of a 6 year old boy, born and lived for four years in Cameroon, who presented a right emiconvulsion. The diagnosis was neurocysticercosis. This case accentuates the need to consider neurocysticercosis in a child presenting with non febrile seizures, mainly if he emigrated from an area of high prevalence or if he had long-term stay in endemic regions.

Reduced bone mass measurements are often found in HIV-infected youths. Both in vitro and human studies demonstrated a role of antiretroviral treatment in determining bone mass alteration. Nevertheless, the data regarding the responsibility of different antiretroviral drugs on bone health in children and adolescents are highly controversial. The purpose of the current study was to relate antiretroviral treatment to bone mass measurements in a large cohort of HIV-infected children and adolescents. Bone mineral content (BMC) was measured in 86 HIV-infected youths (aged 4.8-22.1 years), and in 194 healthy controls (aged 4.9-21.9 years). Fifteen patients were naive to antiretroviral treatment, 11 were receiving a dual nucleoside reverse transcriptase inhibitor (NRTIs) combination, 32 a protease inhibitor (PI)-based antiretroviral treatment, and 28 a non-nucleoside reverse transcriptase inhibitor (NNRTIs)-based regimen. Comparisons between healthy and HIV-infected children and adolescents have been performed by multiple regression analyses to correct for differences in age, sex, and anthropometric measurements. Patients receiving a PI-based treatment had lumbar spine and whole body BMC values significantly lower than healthy children (P

This prospective observational study was designed to assess the incidence of, risk factors for, and outcome of catheter-related bloodstream infection in children undergoing cardiac surgery. A staff specifically trained to handle the central venous catheters with proper aseptic techniques and an appropriate patient to medical staff ratio remain the most effective measures to prevent this infection.
