Abstract
Bowel ultrasound (US) is a low-cost, non-invasive, bed side practice and a reproducible procedure that represents a high yield tool in clinical practice and in the diagnostic workup of a consistent group of acute and chronic gastrointestinal (GI) tract disease. Moreover, in case of GI diseases of neonatal and pediatric age, it allows an easier evaluation due to the small body size and scarce presence of fat tissue in the abdominal wall and peritoneal cavity and gas content. No particular preparation of the patient is needed, nevertheless a 3- to 5-hour fasting state improves the quality of the examination. The exam focuses on wall thickness and stratification, lumen content, distensibility and compressibility, presence of peristalsis of explorable segment of the GI tract and includes the investigation of mesentery, perivisceral tissues and nodes features. Color doppler flowmetry admits a qualitative evaluation of GI wall and mesentery vascularization. Healthy GI wall appears at a US evaluation as a multilayered structure in which hyperechoic and hypoechoic layers alternate sequentially. In this article we provide a quickly available overview on findings, signs and applications of US in major GI pediatric diseases.

Abstract
Pediatric liver transplantation is a challenging surgical procedure requiring complex post-transplant patient management. Liver transplantation in children should ensure long-term survival and good health-related quality of life (HR-QOL), but data in the literature are conflicting. With the aim of investigating survival and psychosocial outcomes of patients transplanted during childhood, we identified 40 patients with ≥ 20-year follow-up after liver transplantation regularly followed up at our Institution. Clinical charts were reviewed to retrieve patients' data. Psychosocial aspects and HR-QOL were investigated by an in-person or telephonic interview and by administering the WHOQOL-BREF questionnaire through an online form. Ten- and 20-year patient survival was 97.5% (95% CI 92.8-100%), whereas 10- and 20-year graft survival was 77.5% (65.6-91.6%) and 74.8% (62.5-89.6%), respectively. At last follow-up visit, 31 patients (77.5%) were receiving a tacrolimus-based immunosuppression. Twelve (32.4%) patients obtained a university diploma or higher, whereas 19 (51.4%) successfully completed high school. 81.1% of patients were active workers or in education, 17.5% had children, and 35% regularly practiced sport. 25 patients answered to the WHOQOL-BREF questionnaire. More than 60% of respondents did not report any disability and the perceived physical status was invariably good or very good. Median scores for physical health, psychological health, social relationships, and environment were 16.6, 14.7, 16, and 15, respectively. Pediatric liver transplantation is associated with excellent long-term survival and good HR-QOL. Psychological health and environment represent areas in which support would be needed to further improve HR-QOL.

Abstract
OBJECTIVES Prevention of vertical transmission of hepatitis B virus (HBV) infection is crucial to eliminate viral hepatitis as a major public health threat by 2030. We aimed to assess the current hospital policies and practices implemented before, at, and after birth, and to evaluate potential barriers to the full application of international guidelines. METHODS A web-based survey was supported by PENTA Foundation and distributed across Europe from October to December 2021. RESULTS Overall, 76 centers with delivery departments completed the survey. Hepatitis B surface antigen (HBsAg) maternal screening is performed in the first trimester of pregnancy in 53% of the centers and in the third in 46%. HBsAg positive pregnant women are tested for serologic HBV markers and HBV-DNA in 78% and 63% of the departments; 38% of the HBeAg positive women with high HBV-DNA levels are treated during the last trimester of pregnancy. At birth, 91% of the departments administer HBV vaccine to infants born to HBsAg positive mothers within 12 hours of birth; 74% test women with unknown HBsAg status and 78% of them wait for the maternal testing results before administering HBV vaccine to their newborns. After birth, 47% of the departments provide postvaccination serological testing for infants born to HBsAg positive mothers. The timing of the HBV vaccine schedule varies greatly. CONCLUSIONS There is significant heterogeneity in the hospital policies and correlated procedures. The implementation of a multidisciplinary clinical pathway is a must if a stronger connection between the prenatal, perinatal, and postnatal phases is to be established.

Abstract
The hepatocyte nuclear factor 1β (HNF1B) gene is involved in the development of specialized epithelia of several organs during the early and late phases of embryogenesis, performing its function mainly by regulating the cell cycle and apoptosis pathways. The first pathogenic variant of HNF1B (namely, R177X) was reported in 1997 and is associated with the maturity-onset diabetes of the young. Since then, more than 230 different HNF1B variants have been reported, revealing a multifaceted syndrome with complex and heterogenous genetic, pathologic, and clinical profiles, mainly affecting the pediatric population. The pancreas and kidneys are the most frequently affected organs, resulting in diabetes, renal cysts, and a decrease in renal function, leading, in 2001, to the definition of HNF1B deficiency syndrome, including renal cysts and diabetes. However, several other organs and systems have since emerged as being affected by HNF1B defect, while diabetes and renal cysts are not always present. Especially, liver involvement has generally been overlooked but recently emerged as particularly relevant (mostly showing chronically elevated liver enzymes) and with a putative relation with tumor development, thus requiring a more granular analysis. Nowadays, HNF1B-associated disease has been recognized as a clinical entity with a broader and more variable multisystem phenotype, but the reasons for the phenotypic heterogeneity are still poorly understood. In this review, we aimed to describe the multifaceted nature of HNF1B deficiency in the pediatric and adult populations: we analyzed the genetic, phenotypic, and clinical features of this complex and misdiagnosed syndrome, covering the most frequent, unusual, and recently identified traits.

Abstract
BACKGROUND Hepatocyte nuclear factor 1B (HNF1B) is a member of the homeodomain-containing family of transcription factors located on 17q12. HNF1B deficiency is associated with a clinical syndrome (kidney and urogenital malformations, maturity-onset diabetes of the young, exocrine pancreatic insufficiency) and to an underdiagnosed liver involvement. Differently from HNF1A, the correlation between hepatocellular carcinoma (HCC) and germline HNF1B deficiency has been poorly evaluated. CASE REPORT Here, we report a novel case of a syndromic HNF1B-deficient paediatric patient that developed HCC with unique histopathological features characterised by neoplastic syncytial giant cells, which was observed only in one additional case of paediatric cholestatic liver disease of unknown origin. CONCLUSIONS Our case highlights the influence of HNF1B deficiency in liver disease progression and its putative association with a rare yet specific HCC histotype. We hypothesised that HCC could be secondary to the repressive effect of HNF1B variant on the HNF1A transcriptional activity.

Abstract
Neonatal and infantile cholestasis (NIC) can represent the onset of a surgically correctable disease and of a genetic or metabolic disorder worthy of medical treatment. Timely recognition of NIC and identification of the underlying etiology are paramount to improve outcomes. Upon invitation by the Italian National Institute of Health (ISS), an expert working grouped was formed to formulate evidence-based positions on current knowledge about the diagnosis of NIC. A systematic literature search was conducted to collect evidence about epidemiology, etiology, clinical aspects and accuracy of available diagnostic tests in NIC. Evidence was scored using the GRADE system. All recommendations were approved by a panel of experts upon agreement of at least 75% of the members. The final document was approved by all the panel components. This position document summarizes the collected statements and defines the best-evidence diagnostic approach to cholestasis in the first year of life.

Abstract
Tacrolimus (TAC) is a first-choice immunosuppressant for solid organ transplantation, characterized by high potential for drug-drug interactions, significant inter- and intra-patient variability, and narrow therapeutic index. Therapeutic drug monitoring (TDM) of TAC concentrations in whole blood (WB) is capable of reducing the incidence of adverse events. Since TAC acts within lymphocytes, its monitoring in peripheral blood mononuclear cells (PBMC) may represent a valid future alternative for TDM. Nevertheless, TAC intracellular concentrations and their variability are poorly described, particularly in the pediatric context. Therefore, our aim was describing TAC concentrations in WB and PBMC and their variability in a cohort of pediatric patients undergoing constant immunosuppressive maintenance therapy, after liver transplantation. TAC intra-PBMCs quantification was performed through a validated UHPLC–MS/MS assay over a period of 2–3 months. There were 27 patients included in this study. No significant TAC changes in intracellular concentrations were observed (p = 0.710), with a median percent change of −0.1% (IQR −22.4%–+46.9%) between timings: this intra-individual variability was similar to the one in WB, −2.9% (IQR −29.4–+42.1; p = 0.902). Among different patients, TAC weight-adjusted dose and age appeared to be significant predictors of TAC concentrations in WB and PBMC. Intra-individual seasonal variation of TAC concentrations in WB, but not in PBMC, have been observed. These data show that the intra-individual variability in TAC intracellular exposure is comparable to the one observed in WB. This opens the way for further studies aiming at the identification of therapeutic ranges for TAC intra-PBMC concentrations.

Abstract
Human endogenous retroviruses (HERVs) represent 8% of our genome. Although no longer infectious, they can regulate transcription of adjacent cellular genes, produce retroviral RNAs, and encode viral proteins that can modulate both innate and adaptive immune responses. Based on this, HERVs have been studied and proposed as contributing factors in various autoimmune disorders. Celiac disease (CD) is considered an autoimmune disease, but HERV expression has not been studied in celiac patients. The aim of this study is to assess the transcription levels of pol genes of HERV-H, -K, and -W and of their TRIM28 repressor in WBCs from celiac children and age-matched control subjects. A PCR real-time TaqMan amplification assay was used to evaluate HERV and TRIM28 transcripts with normalization of the results to glyceraldehyde-3-phosphate dehydrogenase. The RNA levels of pol genes of the three HERV families were significantly higher in WBCs from 38 celiac patients than from 51 control subjects. TRIM28 transcription was comparable between the two study populations.Conclusion: Present results show, for the first time, that pol genes of HERV-H, -K, and -W are overexpressed in patients with CD. Given their proinflammatory and autoimmune properties, this suggests that HERVs may contribute to the development of CD in susceptible individuals. What is Known: • Based on this, HERVs have been studied and proposed as contributing factors in various autoimmune disorders. What is New: • Present results show, for the first time, that pol genes of HERV-H, -K, and -W are overexpressed in patients with CD.

Abstract
Combined liver-kidney transplantation is a therapeutic option for children affected by type 1 primary hyperoxaluria. Persistently high plasma oxalate levels may lead to kidney graft failure. It is debated whether pre-emptive liver transplantation, followed by kidney transplantation, might be a better strategy to reduce kidney graft loss. Our experience of 6 pediatric combined liver-kidney transplants for primary hyperoxaluria type 1 in pediatric recipients was retrospectively analyzed. Plasma oxalate levels were monitored before and after transplantation. All the recipients were on hemodialysis at transplantation. Median [IQR] recipient's age at transplantation was 11 [1-14] years; in all cases, a compatible graft from a pediatric brain-dead donor aged 8 [2-16] years was used. In a median follow-up of 7 [2-19] years after combined liver-kidney transplantation, no child died and no liver graft failure was observed; three kidney grafts were lost, due to chronic rejection, primary non-function, and early renal oxalate accumulation. Liver and kidney graft survival remained stable at 1, 3, and 5 years, at 100% and 85%, respectively. Kidney graft loss was the major complication in our series. Risk is higher with very young, low-weight donors. The impact of treatment with glyoxalate pathway enzyme inhibitors treatment in children with advanced disease as well as of donor kidney preservation by ex vivo machine perfusion needs to be evaluated. At present, a case-by-case discussion is needed to establish an optimal treatment strategy.

Abstract
Acute liver failure (ALF) is a clinical condition characterized by the abrupt onset of coagulopathy and biochemical evidence of hepatocellular injury, leading to rapid deterioration of liver cell function. In children, ALF has been characterized by raised transaminases, coagulopathy, and no known evidence of pre-existing chronic liver disease; unlike in adults, the presence of hepatic encephalopathy is not required to establish the diagnosis. Although rare, ALF has a high mortality rate without liver transplantation (LT). Etiology of ALF varies with age and geographical location, although it may remain indeterminate in a significant proportion of cases. However, identifying its etiology is crucial to undertake disease-specific management and evaluate indication to LT. In this position statement, the Liver Disease Working Group of the Italian Society of Gastroenterology, Hepatology and Nutrition (SIGENP) reviewed the most relevant studies on pediatric ALF to provide recommendations on etiology, clinical features and diagnostic work-up of neonates, infants and children presenting with ALF. Recommendations on medical management and transplant candidacy will be discussed in a following consensus conference.

Abstract
Autoimmune polyendocrinopathy–candidiasis–ectodermal dystrophy (APECED), caused by mutations in the AIRE gene, is mainly characterized by the triad of hypoparathyroidism, primary adrenocortical insufficiency and chronic mucocutaneous candidiasis, but can include many other manifestations, with no currently clear genotype–phenotype correlation. We present the clinical features of two siblings, a male and a female, with the same mutations in the AIRE gene associated with two very different phenotypes. Interestingly, the brother recently experienced COVID-19 infection with pneumonia, complicated by hypertension, hypokalemia and hypercalcemia. Although APECED is a monogenic disease, its expressiveness can be extremely different. In addition to the genetic basis, epigenetic and environmental factors might influence the phenotypic expression, although their exact role remains to be elucidated.

Abstract
OBJECTIVES Sofosbuvir/Ledipasvir (SOF/LDV) has been approved by the European Medicine Agency (EMA) for the treatment of children and adolescents (at least 3 years of age) with chronic hepatitis C (CHC) genotype 1, 3, and 4 infection. The aim of this study was to evaluate the efficacy and safety of SOF/LDV in adolescents (12 to <18 years old) with CHC in the real-world setting. METHODS Prospective, open-label, multicentre study involving 12 Italian centres. Patients received the fixed-dose combination of SOF/LDV (400/90 mg) once daily ± ribavirin as per EMA approval and recommendations. The key efficacy endpoint was sustained virological response 12 weeks after the end of treatment (SVR12) as per intention-to-treat analysis. Safety was assessed by adverse events and clinical/laboratory data. RESULTS Seventy-eight consecutive adolescents (median age 15.2 years, range 12-17.9; girls 53.8%) were enrolled and treated between June 2018 and December 2019. Genotype distribution was as follows: genotype 1 (82.1%), 3 (2.5%), and 4 (15.4%). Seventy-six (97.4%) patients completed treatment and follow-up. Overall, SVR12 was 98.7%. One patient was lost to follow-up after 4 weeks of treatment; 1 patient completed treatment and missed the follow-up visit. No virological breakthrough or relapse were observed. No patient experienced grade 3 to 4 adverse event or serious adverse event. CONCLUSIONS The results of this real-world study confirmed the high efficacy and the optimal safety profile of SOF/LDV for treatment of CHC in adolescents.

Abstract
Abstract
Background
The prevention of perinatal Hepatitis B virus (HBV) is crucial to reach the WHO's challenge to eliminate viral hepatitis as public health threat by 2030. After diagnosing 2 infants infected by vertical transmission, a retrospective analysis of policies and practices to prevent HBV congenital infection was conducted to assess any potential risk.
Methods
Paired maternal-infant medical records between 2017 and 2019 were reviewed at A.O.U Città della Salute e Scienza di Torino, the italian hospital with the highest number of deliveries. Data included maternal HBSAg and coinfection (HIV, HCV) status and the administration of prophylaxis in newborns at risk. Other serologic markers of HBV maternal infection were not available.
Results
132 (0,6%) newborns from HBsAg positive mothers were identified between 2017-2019 among 21143 newborns. In this group pre-natal HBSAg status was known in 127 (96,2%), the remaining were tested during the hospitalization. Regarding maternal coinfection 130 (98%) were tested for HIV (1 positive), only 60 (45.1%) for HCV (all negative). All newborns received immunoprophylaxis consisting in the administration of vaccination and immunoglobulin: 119 (89%) within 24 hours (63% within 12 hours), 12 (9%) between 24-36 hours and 2 (1,6%) after 36 hours. The 2 cases of vertical transmission, even if correctly vaccinated, show a vaccination failure of 1,5%.
Conclusions
Although most of the mothers were tested for HBSAg status and all newborns were given immunoprophylaxis, vaccination failure seems to explain the 2 cases of vertical transmission. Since the lack in early maternal serologic screening and the late vaccination time could increase the risk of HBV infection, to achieve WHO goal we suggest to implement a multidisciplinary pathway to identify HBV positive mothers, to treat in case of high viral load, to provide a timely immunoprophylaxis considering a early vaccination and to set up a structured postnatal serologic check for newborns at risk.
Key messages
Vaccination failure must be considered in the service organization, a structured postnatal serologic check for all newborns at risk should be implemented to detect potential vaccination failure. A multidisciplinary pathway to identify HBV positive mothers, with a full serological markers set, should be implemented to give a correct maternal therapy and newborn prophylaxis.

Abstract
Background paucity of interlobular bile ducts is an important observation at liver biopsy in the diagnostic work-up of neonatal cholestasis. To date, other than in the Alagille syndrome, syndromic paucity of interlobular bile ducts has been documented in four cholestatic neonates with HFN1β mutations. A syndromic phenotype, known as renal cysts and diabetes syndrome (RCAD), has been identified. This is usually characterized by a wide clinical spectrum, including renal cysts, maturity-onset diabetes of the young, exocrine pancreatic insufficiency, urogenital abnormalities and a not well established liver involvement. Herein we report a novel case of paucity of interlobular bile ducts due to an HFN1β defect. Case presentation A 5-week-old boy was admitted to our department for cholestatic jaundice with increased gamma-glutamyl transpeptidase and an unremarkable clinical examination. He had been delivered by Caesarian section at 38 weeks’ gestation from unrelated parents, with a birth weight of 2600 g (3rd percentile). Screening for cholestatic diseases, including Alagille syndrome, was negative except for a minor pulmonary artery stenosis at echocardiography and a doubt of a thoracic butterfly hemivertebra. The finding of hyperechogenic kidneys with multiple bilateral cortical cysts at ultrasound examination, associated with moderately impaired renal function with proteinuria, polyuria and metabolic acidosis, was suggestive of ciliopathy. A liver biopsy was performed revealing paucity of interlobular bile ducts, thus the diagnosis of Alagille syndrome was reconsidered. Although genetic tests for liver cholestatic diseases were performed with negative results for Alagille syndrome (JAG1 and NOTCH2), a de-novo missense mutation of HNF1β gene was detected. At 18 months of age our patient has persistent cholestasis and his itching is not under satisfactory control. Conclusions Alagille syndrome may not be the only syndrome determining paucity of interlobular bile ducts in neonates presenting with cholestasis and renal impairment, especially in small for gestational age newborns. We suggest that HNF1β deficiency should also be ruled out, taking into consideration HNF1β mutations, together with Alagille syndrome, in next generation sequencing strategies in neonates with cholestasis, renal impairment and/or paucity of interlobular bile ducts at liver biopsy.

Abstract
Although about 35 years have elapsed since the discovery of the Helicobacter pylori, its diagnosis and the choice of optimal eradication therapy are still to be defined. Over time, there has been an increase in interest, publications, recommendations and guidelines. Moreover, management of the disease in pediatric subjects differs somewhat to that of adults and requires a more delicate approach leading to alternative strategies for both diagnosis and treatment. Which patient should be investigated for H. pylori, when to perform noninvasive or invasive tests, what are the proper therapeutic options and best antibiotics regimen to eradicate the infection are practices changing with evidences through time. Therefore, an updated guideline was published by the European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) in 2017. The aim of this review is to highlight what is new and what differs between adult and pediatric population regarding the management of H. pylori infection after the ESPGHAN/NASPGHAN guidelines, enriched with updates from literature reviews published over the last two years.

Abstract
As graft survival in pediatric LT is often affected by progressive fibrosis, numerous centers carry out protocol liver biopsies. Follow-up biopsy protocols differ from center to center, but all biopsies are progressively spaced out, as time from transplant increases. Therefore, there is a need for non-invasive techniques to evaluate graft fibrosis progression in those children who have no clinical or serological signs of liver damage. Indirect markers, such as the APRI, should be relied on with caution because their sensitivity in predicting fibrosis can be strongly influenced by the etiology of liver disease, severity of fibrosis, and patient age. A valid alternative could be TE, a non-invasive technique already validated in adults, which estimates the stiffness of the cylindrical volume of liver tissue, 100-fold the size of a standard needle biopsy sample. The aims of this study were to evaluate the reliability of TE in children after LT and to compare both the TE and the APRI index results with the histological scores of fibrosis on liver biopsies. A total of 36 pediatric LT recipients were studied. All patients underwent both TE and biopsy within a year (median interval -0.012 months) at an interval from LT of 0.36 to 19.47 years (median 3.02 years). Fibrosis was assessed on the biopsy specimens at histology and staged according to METAVIR. There was a statistically significant correlation between TE stiffness values and METAVIR scores (P = .005). The diagnostic accuracy of TE for the diagnosis of significant fibrosis (F ≥ 2) was measured as the area under the curve (AUROC = 0.865), and it demonstrated that the method had a good diagnostic performance. APRI was not so accurate in assessing graft fibrosis when compared to METAVIR (AUROC = 0.592). A liver stiffness cutoff value of 5.6 kPa at TE was identified as the best predictor for a significant graft fibrosis (METAVIR F ≥ 2) on liver biopsy, with a 75% sensitivity, a 95.8% specificity, a 90% positive predictive value, and an 88.5% negative predictive value. These data suggest that TE may represent a non-invasive, reliable tool for the assessment of graft fibrosis in the follow-up of LT children, alerting the clinicians to the indication for a liver biopsy, with the aim of reducing the number of protocol liver biopsies.

Abstract
Background Pediatric acute-liver-failure due to acetaminophen (APAP) administration at therapeutic dosage is rare, while viral infections and metabolic defects are the prevalent causes. Yet, as acetaminophen is routinely used in febrile illnesses, it may be mistakenly held responsible for the acute liver damage. Case presentation An 11 month old boy had been on acetaminophen for 10 days (total dose 720 mg = 72 mg/kg) when he developed acute-liver-failure with encephalopathy. As he rapidly improved on N-acetylcysteine (NAC) infusion, it was concluded that chronic acetaminophen administration in an infant had lead to acute-liver-failure even at therapeutic doses, that N-acetylcysteine infusion had been life-saving and should be immediately started in similar circumstances. The child, however, had two further episodes of acute liver damage over a 34-month period, without having been given acetaminophen, as the parents carefully avoided using it. His clinical, laboratory and radiological findings between the acute episodes were unremarkable. His features and skeletal surveys were not suggestive of a syndromic condition. He then went on to suffer another episode of acute-liver-failure with multi-organ failure, necessitating an urgent liver transplant. All efforts to come to a diagnosis for the causes of his recurrent episodes of liver failure had been unsuccessful, until a biallelic mutation in the NBAS gene was reported to be associated with recurrent acute-liver-failure in children. The boy’s DNA analysis revealed compound heterozygous pathogenic mutations in the NBAS gene. Liver failure episodes in these patients are triggered and worsened by fever, most likely due to thermal susceptibility of hepatocytes, hence APAP, rather than being a culprit, is part of the supportive treatment. Conclusions We suggest that, in acute-liver-failure with a history of acetaminophen exposure at therapeutic dosage, clinicians should not be contented with administering NAC, but should consider an alternative etiology, above all if the episodes are recurrent, and actively start supportive and antipyretic treatment while seeking the advice of a specialist unit.

Abstract
We report on a 12-year-old adopted boy with psychomotor disability, absence seizures, and normal brain MRI. He showed increased (but initially, at 5 months, normal) serum cholesterol, increased alkaline phosphatases, transiently increased transaminases and hypoceruloplasminemia with normal serum and urinary copper. Blood levels of immunoglobulins, haptoglobin, antithrombin, and factor XI were normal. A type 2 serum transferrin isoelectrofocusing and hypoglycosylation of apoCIII pointed to a combined N- and O-glycosylation defect. Neither CDG panel analysis with 79 CDG-related genes, nor whole exome sequencing revealed the cause of this CDG. Whole genome sequencing was not performed since the biological parents of this adopted child were not available.

Abstract
Tacrolimus (TAC, FK-506) and everolimus (EVE, RAD001) are immunosuppressors used to treat pediatric patients undergoing liver transplantation. Their hematic TDM by liquid chromatography became standard practice. However, it does not always reflect concentrations at their active site. Our aim was to develop and validate a new method for the simultaneous TAC and EVE quantification into target cells: peripheral blood mononuclear cells (PBMCs). Peripheral blood mononuclear cells were collected using cell preparation tubes; cells number and mean cell volume were evaluated by an automatic cell counter. TAC and EVE were quantified using UHPLC-MS/MS coupled with an automated online solid-phase extraction platform. Chromatographic run was performed on an Acquity UPLC® BEH C18 1.7 μm (2.1 × 50 mm) column at 45 °C, for 6 min at 0.5 ml/min. Mobile phases were water and methanol, both with 2 mm ammonium acetate and 1 ml/l formic acid). XBridge® C8 10 μm (1 × 10 mm) SPE cartridges were used, and the internal standard was ascomycin. Following Food and Drug Administration guidelines, method validation resulted in high sensitivity and specificity. Calibration curves were linear (r2 = 0.998) and intra-day and inter-day imprecision and inaccuracy were <15%. A reproducible matrix effect was observed, with a good recovery for all compounds. Drug amounts in 15 'real' PBMCs samples from five pediatric patients in co-treatment resulted within the calibration range (0.039-5 ng). Concentrations from each patient were standardized using their evaluated mean cell volume: intra-PBMCs concentration was meanly 19.23 and 218.61 times higher than the hematic one for TAC and EVE, respectively. This method might be useful in clinical routine, giving reliable data on drugs concentration at the active site. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
AIM The aim of the present study was to investigate the influence of the cytochrome P450 (CYP) 3A4/5 genotype in paediatric liver transplant recipients and donors, and the contribution of age and gender to tacrolimus disposition on the first day after transplantation. METHODS The contribution of the CYP3A4/5 genotype in paediatric liver transplant recipients and donors to the tacrolimus blood trough concentrations (C0 ) and the tacrolimus concentration/weight-adjusted dose ratio on day 1 was evaluated in 67 liver-transplanted children: 33 boys and 34 girls, mean age 4.5 years. RESULTS Donor CYP3A5 genotype appears to be significantly associated with tacrolimus disposition on the first day after liver transplantation (P < 0.0002). Other physiological factors, such as recipient age and donor gender may also play a role and lead to significant differences in tacrolimus C0 and tacrolimus concentration/weight-adjusted dose ratio on day 1. However, according to the general linear model, only recipient age appears to be independently associated with tacrolimus disposition on the first day after liver transplantation (P < 0.03). Indeed, there was a faster tacrolimus metabolism in children under 6 years of age (P < 0.02). CONCLUSIONS Donor CYP3A5 genotype, recipient age and, to a lesser extent, donor gender appear to be associated with tacrolimus disposition on day 1 after transplant. This suggests that increasing the starting tacrolimus doses in paediatric patients under 6 years of age who receive a graft from a male extensive metabolizer may enhance the possibility of their tacrolimus levels reaching the therapeutic range sooner.

Abstract
BACKGROUND Human endogenous retrovirus (HER Vs) constitute approximately 8% of the human genome. Induction of HER V transcription is possible under certain circumstances, and may have a possible role in some pathological conditions. Aim of the present study was to verify whether HER V-W and K activation by Epstein Barr Virus (EBV) might occur also in vivo, during EBV infection, in pediatric liver transplant recipients. METHODS A total of 35 pediatric liver transplant (LT) patients who received LT at the University Hospital City of Science and Health of Turin, Regina Margherita Children's Hospital were included. The samples were grouped in EBV negative and positive. RESULTS We found that HER V-K, and HER V-W expression levels showed no differences between the two groups (P=0.533 HERV-W and P=0.6017 HERV-K). There was not was a significant difference P=0.1894 and 0.1705 for HERV-W and -K respectively when we compared transplant recipients' group with high EBV viral load vs. others transplant recipients. CONCLUSIONS Our data suggest that EBV does not facilitate in-vivo HERV activation.

Abstract
Oral myiasis is a condition in which tissues of the oral cavity are invaded by the larvae of flies. It is a rare disease in humans, often associated with very poor dental and oral hygiene. In children the main predisposing factors are incompetent lips, thumb sucking habits and continuous mouth breathing. The condition has been reported mainly in Asia and South America and rarely in more developed countries. The cases recorded in Italy concern adults with ocular or cutaneous manifestations alone. We describe an unusual infestation of the oral cavity of a five-year-old Italian boy with a severe congenital heart defect. He presented a gingival swelling and, after a few hours, some larvae could be seen moving through his oral cavity. They were removed manually and an oral antibiotic was given to avoid a bacterial superinfection. Three days after, oral examination of the patient revealed a gradual decrease in gingival swelling; complete clinical resolution was achieved about two weeks later. This case is reported as a reminder to consider oral myiasis in the event of suspected gingival swelling in children, especially if they have predisposing factors or if they come from an endemic area.

Abstract
BACKGROUND This prospective surveillance study was designed to estimate the incidence of healthcare-associated infections (HAIs) and to analyze the risk factors for their development in a pediatric neurosurgical unit. METHODS The study was performed in an Italian teaching hospital from October 2008 through March 2010. All children (0-18 years) undergoing neurosurgery were included and monitored daily for the development of HAIs. RESULTS The study included 260 patients, with a mean age of 4.3 ± 4.7 years. Thirty-six HAIs were detected in 25 patients; catheter-related infections were the most frequent. Etiological identification was available in 22 cases; Gram-negative bacteria were the most commonly isolated pathogens. The incidence density was 11.0/1,000 patient days, and the incidence rate was 13.8/100 patients. The crude mortality was 0%. The risk of developing HAIs was related to the length of hospital stay, while the higher the age of the patients, the lower the risk of developing HAIs. CONCLUSION To our knowledge, this survey is the first study to evaluate the overall incidence of HAIs and to explore the risk factors implicated in their development in neurosurgical pediatric patients. The most effective strategies to prevent these infections are reduction of the length of the hospital stay and improvement in device management.

Abstract
Clinical features and outcome of 2009 H1N1 influenza virus in the paediatric setting is ill-defined. The epidemiologic and clinical features of children with confirmed H1N1 influenza virus infection admitted to an Italian tertiary paediatric hospital from August through December 2009 were evaluated. A total of 63 children (mean age 4.3 years) were studied; of these, 29 (46%) had chronic underlying diseases. The most frequent symptoms and signs at admission were fever (97%), cough (60%) and respiratory disturbances (24%). Forty patients (63.5%) had H1N1-related complications: 32 (51%) pulmonary diseases, three (5%) neurological disorders, such as acute encephalitis or acute disseminated encephalomyelitis, and two (3%) haematological alterations. Three patients were admitted to the Intensive Care Unit. Most children (81%) were treated with oseltamivir: one developed rash during treatment; no other adverse events were noticed. All children survived without sequelae. In conclusions, 2009 H1N1 influenza virus infection in children is associated with a wide spectrum of clinical manifestations. Neurological disorders are not exceptional complications. Oseltamivir therapy seems safe also in infants.

Abstract
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.

Abstract
The objective of the study was to evaluate the association between infectious diseases and other events pertaining to childhood medical history and type 1 diabetes. A case-control study was carried out, taking as cases 159 type 1 diabetic patients (0-29 years) recorded from 1988 to 2000 within the population registry of the Pavia province (North Italy). As controls 318 non-diabetic subjects were matched by age and sex. A questionnaire was administered by standardised interviewers. Data were analysed by conditional logistic regression. Viral childhood diseases (OR 4.29; 95%CI 1.57-11.74) and bottle feeding (OR 1.83; 95%CI 1.08-3.09) were directly correlated to type 1 diabetes; an inverse correlation was found for vitamin D administration during lactation (0-14 years) (OR 0.31; 95%CI 0.11-0.86) and for history of scarlet fever in both sexes and age groups (OR 0.19; 95%CI 0.08-0.46). Most associations of the studied variables confirm already known findings. The significant inverse correlation of type 1 diabetes with scarlet fever history is a peculiar finding, the meaning of which is still obscure, although it has been recently described that streptococcal A infections are regulated by HLA class II alleles.
