RESUMO
BACKGROUND AND AIMS: Upper endoscopy procedures (UEP, esophagogastroduodenoscopy [EGDS] and retrograde endoscopic retrograde cholangiography [ERCP]) are an established standard of care in pediatric gastroenterology. The Pediatric endoscopy quality improvement network (PEnQuIN) recently published its pediatric-specific endoscopy quality guidelines. This study, initiated by the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP), aims to evaluate the adherence of Italian Pediatric Endoscopy Centers to these established quality standards. METHODS: Conducted between April 2019 and March 2021, this nationwide study utilized a smartphone app-based approach. Data encompassing pediatric endoscopy facilities, patient profiles, endoscopy indications, 17 procedure-related PEnQuIN indicators, and a GHAA-9m patient satisfaction questionnaire were systematically collected. RESULTS: A comprehensive analysis of 3582 procedures from 24 PECs revealed that 2654 (76%) were UEP. The majority of centers (75%) involved more than one operator, with 9 PEC incorporating adult endoscopists, responsible for 5% of UEPs. Overall, adherence to quality standards was good; however, areas of improvement include sub-optimal reporting of sedation details, adherence to disease-specific guidelines, and patient satisfaction questionnaire completeness (56%). The complication rate aligned with literature standards (1%), and patient satisfaction was generally high. A noteworthy observation was a 30% decrease monthly reporting rate and a shift in disease-specific patterns following the COVID-19 outbreak. CONCLUSIONS: Pediatric UEP practices in Italy adhere well to established quality standards. Emphasizing the adoption of disease-specific guidelines is crucial for optimizing resources, enhancing diagnostic accuracy, and minimizing unnecessary procedures. Prioritizing patient satisfaction is important for immediate enhancements in practice as well as for future research endeavors.
RESUMO
Jansen-de Vries syndrome (JdVS) is a neurodevelopmental condition attributed to pathogenic variants in Exons 5 and 6 of PPM1D. As the full phenotypic spectrum and natural history remain to be defined, we describe a large cohort of children and adults with JdVS. This is a retrospective cohort study of 37 individuals from 34 families with disease-causing variants in PPM1D leading to JdVS. Clinical data were provided by treating physicians and/or families. Of the 37 individuals, 27 were male and 10 female, with median age 8.75 years (range 8 months to 62 years). Four families document autosomal dominant transmission, and 32/34 probands were diagnosed via exome sequencing. The facial gestalt, including a broad forehead and broad mouth with a thin and tented upper lip, was most recognizable between 18 and 48 months of age. Common manifestations included global developmental delay (35/36, 97%), hypotonia (25/34, 74%), short stature (14/33, 42%), constipation (22/31, 71%), and cyclic vomiting (6/35, 17%). Distinctive personality traits include a hypersocial affect (21/31, 68%) and moderate-to-severe anxiety (18/28, 64%). In conclusion, JdVS is a clinically recognizable neurodevelopmental syndrome with a characteristic personality and distinctive facial features. The association of pathogenic variants in PPM1D with cyclic vomiting bears not only medical attention but also further pathogenic and mechanistic evaluation.

BACKGROUND: Aim of the present report was to investigate the repercussions of COVID-19 pandemic on the procedural volumes and on the main indications of pediatric digestive endoscopy in Italy. METHODS: An online survey was distributed at the beginning of December 2020 to Italian digestive endoscopy centers. Data were collected comparing two selected time intervals: the first from 1st of February 2019 to 30th June 2019 and the second from 1st February 2020 to 30th June 2020. RESULTS: Responses to the survey came from 24 pediatric endoscopy Units. Globally, a reduction of 37.2% was observed between 2019 and 2020 periods with a significant decrease in median number of procedures (111 vs 57, p < 0.001). Both the median number of procedures performed for new diagnoses and those for follow-up purposes significantly decreased in 2020 (63 vs 36, p < 0.001 and 42 vs 21, p< 0.001, respectively). We reported a drastic reduction of procedures performed for suspected Celiac Disease and Functional Gastrointestinal Disorders (55.1% and 58.0%, respectively). Diagnostic endoscopies for suspected IBD decreased of 15.5%, whereas procedures for Mucosal Healing (MH) assessment reduced of 48.3%. CONCLUSIONS: Our study provides real-world data outlining the meaningful impact of COVID-19 on pediatric endoscopy practice in Italy.

OBJECTIVES: The incidence of choledocolithiasis is reported to be increasing in children. As for the adult population, several different therapeutic strategies have been described, however it is unclear which of those should be considered the gold standard. There is evidence-based literature in adults that supports a combined "rendez-vous" endoscopic retrograde cholangiopancreatography-laparoscopic cholecystectomy technique. This allows management of the choledocholithiasis during the same anesthetic episode as the cholecystectomy. By contrast, there are just two case reports in children reporting this approach. The aim of this study is to report our experience with this technique in a series of children with choledocholithiasis. METHODS: All patients who underwent the "rendez-vous technique" at our institution between 2009 and 2020 were reviewed and evaluated for outcomes and complications. RESULTS: Eleven children with cholecysto-choledocholithiasis were evaluated: the procedure was successful in 10 whereas in one patient it was aborted due to technical difficulties. All patients resolved their clinical condition without major complications. CONCLUSION: To our knowledge, this is the first consistent series of "rendez-vous technique" in the pediatric population, proving its feasibility and safety.

BACKGROUND: The impact of graft fibrosis and inflammation on the natural history of pediatric liver transplants is still debated. Our objectives were to evaluate the evolution of posttransplant fibrosis and inflammation over time at protocol liver biopsies (PLBs), risk factors for fibrosis, presence of donor-specific antibodies (DSAs), and/or their correlation with graft and recipient factors. METHODS: A single-center, retrospective (2000-2019) cross-sectional study on pediatric liver transplant recipients who had at least 1 PLB, followed by a longitudinal evaluation in those who had at least 2 PLBs, was conducted. Fibrosis was assessed by the Liver Allograft Fibrosis Semiquantitative score, inflammation by the rejection activity index, DSAs by Luminex. RESULTS: A total of 134 PLBs from 94 patients were included. Fibrosis was detected in 87% (30% mild, 45% moderate, and 12% severe), 80% in the portal tracts. There was an increase in fibrosis between the 1-3 and the 4-6 y group (P = 0.01), then it was stable. Inflammation was observed in 44% (30% mild, 13% moderate, and 1% severe), 90% in the portal tracts. Anti-HLA II (IgG) DSAs were detected in 14 of 40 (35%). Portal fibrosis was associated with portal inflammation in the 1-3 y group (P = 0.04). Low immunosuppression levels were correlated with sinusoidal fibrosis (P = 0.04) and DSA positivity (P = 0.006). There was no statistically significant correlation between DSA positivity and the presence of graft fibrosis or inflammation. CONCLUSIONS: This study corroborates the concept of an early evolution of silent graft fibrosis. Suboptimal immunosuppression may play a role in the development of fibrosis and DSAs.

BACKGROUND Intussusception is the most common cause of intestinal obstruction in children, with a peak incidence usually before the second year of age, while in neonates it is a rare entity. We describe a delayed and incidental diagnosis of neonatal intussusception secondary to Meckel's diverticulum in a neonate with shaken baby syndrome (SBS). This is, to the best of our knowledge, the first reported case of a neonatal intussusception with a Meckel's diverticulum as a lead point in a neurologically impaired child. CASE REPORT A term baby presented at 22 days of age at our Emergency Department in severe conditions due to a suspected SBS. Eight days following hospitalization in the Intensive Care Unit, an isolated episode of rectal bleeding occurred, without any worsening of general conditions or abdominal distension. The ultrasonography showed a "doughnut sign" with high suspicion of ileocecal intussusception. A rectal barium contrast enema was performed but was not resolutive. At exploratory laparotomy an ileocecal intussusception with Meckel's diverticulum acting as a lead point was identified and an intestinal resection was needed due to the ischemic condition of the ileum. The post-operative course was uneventful and the baby recovered well; the residual neurological impairment needed long-term follow-up. CONCLUSIONS Intussusception is a rare entity in neonates and, when severe neurological impairment is present, the diagnosis can be missed because of the compromised condition of the baby and the paucity of gastrointestinal manifestations. In addition, due to the high incidence of lead point in neonatal cases, we recommend reserving non-operative treatment only for selected cases.

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.

Tacrolimus (TAC) pharmacokinetics is influenced by the donor CYP3A5 genotype and the age of pediatric liver recipients. However, an optimization of a genotype-based algorithm for determining TAC starting is needed to earlier achieve stable target levels. As the graft itself is responsible for its metabolism, the Graft-to-Recipient Weight Ratio (GRWR) might play a role in TAC dose requirements. A single-center study was carried out in a cohort of 49 pediatric recipients to analyse the impact of patient and graft characteristics on TAC pharmacokinetics during the first 15 post-transplant days. Children < 2 years received grafts with a significantly higher GRWR (4.2%) than children between 2-8 (2.6%) and over 8 (2.7%). TAC concentration/weight-adjusted dose ratio was significantly lower in recipients from CYP3A5*1/*3 donors or with extra-large (GRWR > 5%) or large (GRWR 3-5%) grafts. The donor CYP3A5 genotype and GRWR were the only significant predictors of the TAC weight adjusted doses. Patients with a GRWR > 4% had a higher risk of acute rejection, observed in 20/49 (41%) patients. In conclusion, TAC starting dose could be guided according to the donor CYP3A5 genotype and GRWR, allowing for a quicker achievement of target concentrations and eventually reducing the risk of rejection.

OBJECTIVES: The aims of the study was to expand the pediatric experience on hepatitis-B virus (HBV) reactivation, a known complication in patients with hematologic malignancies or on immunosuppression. METHODS: Retrospective appraisal of HBV therapy/prophylaxis in immunocompromised children, studied from April 2006 to March 2020. RESULTS: Eighteen HBV-positive patients, 5 girls, median age 11.1 (4.1--17.9) years were included. Seventeen of 18 were immunosuppressed at HBV-infection diagnosis. Seventeen were at high risk of reactivation, 1 at moderate risk. Five of 18 had acute hepatitis B as first infection or reactivation, 6 had HBeAg-positive infection, 1 an HBeAg-negative infection and 6 HBsAg-negative infection. Median follow-up was 2.7 (0.7--12.5) years. No HBV-related mortality was observed. Prophylaxis had to be repeated in 1. Lamivudine was used in 6/12 viremic patients and HBV-DNA negativization obtained in 2/6 (33%). Tenofovir-DF was used in 2/12 and entecavir in 4/12: 100% attained HBV-DNA negativization. Therapy had to be switched from tenofovir-DF to entecavir in 1 patient because of renal impairment. Virological breakthroughs were observed in 1 lamivudine-treated patient, leading to a hepatitis flare; 1 patient on entecavir had a hepatitis flare at immunoreconstitution. Mortality was 33% in the HBsAg-positive group. Seven prophylactic treatments were administered to 6 patients with HBsAg-negative infection: tenofovir-DF in 2 HBV-DNA-positive, lamivudine in 5 HBV-DNA-negative, without reverse HBsAg seroconversion, morbidity or mortality. CONCLUSIONS: There is a residual risk of acute hepatitis B in immunocompromised children, mortality rate was substantial, potentially related to the delays in commencing chemotherapy caused by liver dysfunction. Tenofovir-DF or entecavir are the drugs of choice for HBV treatment in immunocompromised children.

In February 2020, the COVID-19 pandemic overwhelmed Italy. We retrospectively reviewed all attendances and emergency (A&E) admissions due to foreign-body ingestions (FBIs) to an Italian pediatric referral hospital, from February 24 to April 24, 2020, COVID-19 lockdown and compared them with the same period in the previous 4 years. A total of 101 cases were recorded. Mean age of admission was 4.6 years. Groups did not differ for gender (P = 0.4) or age (P = 0.3). Among FBIs ingestions, 24.0% occurred in children with <2 years of age and 47.5% in children from 2 to 6 years of age. In the 2020 study period, 9 patients were seen for batteries ingestion compared with a median value of one among compared periods. The rates of batteries ingestions increased significantly over the observational period (P < 0.001). We report a dramatic increase in batteries ingestions in children, a potentially fatal event, during the COVID-19 pandemic lockdown.
RESUMO
Calprotectin is a calcium and zinc-binding protein, formed by a hetero complex of S100A8 and S100A9 proteins, which belong to the S-100 protein family consisting in more than 20 different proteins with a tissue-specific expression pattern. This protein is secreted extracellularly from stimulated neutrophils or released by cell disruption or death. The presence of calprotectin in feces quantitatively relates to neutrophil migration toward the gastrointestinal (GI) tract; thus, it represents a useful marker of intestinal inflammation. Fecal calprotectin (FC) has been proven largely useful for determining the inflammatory origin of GI symptoms differentiating between organic and non-organic diseases. Indeed, increased FC levels are also seen in gastroenteritis, microscopic colitis, polyps, malignancies and cystic fibrosis. To date, there are many evidences regarding usefulness in the detection of fecal calprotectin for the management of gastrointestinal disorders, both in children and adults but, especially in the pediatric population, still clear indications for its use are lacking. Its incorporation in primary care reduces the risk of missing an organic disease and facilitates the indication for expensive and invasive investigations as colonoscopy. We herein review and discuss the last evidence on the usefulness of FC in children, with its current indications and future prospective.

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 HFN1ß 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 HFN1ß 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 HNF1ß 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 HNF1ß deficiency should also be ruled out, taking into consideration HNF1ß 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.

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.

BACKGROUND: Liver biopsies in pediatric hematopoietic stem cell transplantation (HSCT) patients are as and effective when performed at bedside in the Bone Marrow Transplant Unit (BMTU) than in the Day Surgery Unit (DSU), with better patient compliance and lower emotional distress for these children. METHODS: The study group consisted of 45 children who underwent allogeneic HSCT. We reviewed 68 liver biopsies performed between April 2006 and September 2015. 12 (17.6 %) biopsies were performed in the DSU and 56 (82.3 %) in the BMTU; nine (13.2 %) prior to HSCT and 59 (86.7 %) after HSCT. Pre-procedural behavioral status (subjective score) was evaluated by pediatric transplant physicians by filling in a questionnaire employing a three-point scale: "calm and cooperative", "agitated and non-cooperative" or "frightened and suffering". Objective score was obtained measuring patient's heart rate before the procedure and comparing it with mean heart rate. RESULTS: Patients who underwent the procedure at the BMTU experienced less emotional distress than those who underwent it in the DSU: 58.3 % of patients treated at the DSU were agitated as compared with 16.1 % of those treated at the BMTU (p < 0.01). Among the 59 biopsies performed after HSCT, 41 (69.5 %) were taken from symptomatic patients for a diagnostic purpose and 18 (30.5 %) in asymptomatic ones in order to rule out hepatic GVHD. Among these 18 procedures, GVHD was diagnosed in 16 (88.9 %) cases. Minor complications occurred in about 17 % of procedures (12 biopsies), at a rate of 25 % for the DSU location compared with 16 % for the BMTU location. Only two major complications were reported, one in the DSU and one in the BMTU. CONCLUSION: Liver biopsy performed at bedside in HSCT patients does not carry a higher risk of adverse events than the same procedure performed in the DSU and has lower emotional distress associated with better patient compliance, thus contributing significantly to a higher standard of care.

Acquired torticollis is a common clinical finding in children evaluated in the pediatric emergency department. It may be the presentation symptom of different illnesses, such as trauma, muscle contraction, infections, or malignancies, and an accurate differential diagnosis is required to correctly identify the cause and choose the right treatment. Spondylodiscitis is a low-grade bacterial infection that involves intervertebral disks and the adjacent vertebral bodies. Spondylodiscitis of the cervical spine is unusual and may be a rare cause of torticollis. We report the case of a 4-year-old male patient admitted to the emergency department for a 5-day history of painful torticollis. Blood tests showed an elevated erythrocyte sedimentation rate. The radiograph of the cervical spine showed a thin fifth cervical soma. The magnetic resonance imaging of cervical spine showed the alteration of cervical vertebral bodies and intervertebral disks, suggesting the diagnosis of cervical spondylodiscitis. The patient recovered after endovenous antibiotic treatment. We suggest that cervical spondylodiscitis should be suspected and investigated by means of an magnetic resonance imaging in every case of unexplained torticollis with persisting symptoms.

INTRODUCTION: In recent years, defibrotide (DFT) has emerged as a promising therapy for veno-occlusive disease (VOD). The aim of this study was to investigate whether DFT prophylaxis affects neutrophil engraftment in patients undergoing hematopoietic stem cell transplantation (HSCT). METHODS: A cohort of 44 consecutive pediatric patients who underwent HSCT was retrospectively analyzed to see the role of DFT on engraftment. Patients were assigned into two groups based on the use or non-use of prophylaxis with DFT. RESULTS: The mean time to engraftment was statistically different between the two groups for both polymorphonuclear neutrophils (PMN) and white blood cells. CONCLUSION: Our study supports the hypothesis that prophylaxis with DFT for VOD leads to a delay to the engraftment of PMN in pediatric patients that underwent HSCT.
