RESUMO
PURPOSE: Posthemorrhagic hydrocephalus (PHH) and necrotizing enterocolitis (NEC) are two comorbidities associated with prematurity. The management of patients with both conditions is complex and it is necessary to intercept them to avoid meningitis and multilocular hydrocephalus. METHODS: In a single-center retrospective study, we analyzed 19 patients with NEC and PHH admitted from 2012 to 2022. We evaluated perinatal, imaging, and NEC-related data. We documented shunt obstruction and infection and deaths within 12 months of shunt insertion. RESULTS: We evaluated 19 patients with NEC and PHH. Six cases (31.58%) were male, the median birth weight was 880 g (650-3150), and the median gestational age was 26 weeks (23-38). Transfontanellar ultrasound was performed on 18 patients (94.74%) and Levine classification system was used: 3 cases (15.79%) had a mild Levine index, 11 cases (57.89%) had moderate, and 5 cases (26.32%) were graded as severe. Magnetic resonance showed intraventricular hemorrhage in 14 cases (73.68%) and ventricular dilatation in 15 cases (78.95%). The median age at shunt insertion was 24 days (9-122) and the median length of hospital stay was 120 days (11-316). Sepsis was present in 15 cases (78.95%). NEC-related infection involved the peritoneal shunt in 4 patients and 3 of them had subclinical NEC. At the last follow-up, 6 (31.58%) patients presented with psychomotor delay. No deaths were reported. CONCLUSIONS: Although recognition of subclinical NEC is challenging, the insertion of a ventriculoperitoneal shunt is not recommended in these cases and alternative treatments should be considered to reduce the risk of meningitis and shunt malfunction.

BACKGROUND: Sternal cleft (SC), a rare thoracic malformation, is associated with pectus excavatum (PE) in 2.6-5% of cases. It remains unclear if these conditions are congenitally linked or if SC repair triggers PE. To investigate the potential higher frequency of PE in SC cases, we conducted a retrospective study of our SC patients. METHODS: We assessed PE incidence, progression, and management in SC patients treated at our institute from 2006 to 2022. When available, we collected pre-SC repair CT scan data, calculating the Haller Index (HI) and Correction Index (CI) and compared them to a selected control group. RESULTS: Among 8 SC patients, 7 had concomitant PE (87.5%), varying in severity. PE management ranged from observation to thoracoplasty, depending on its degree. We observed a significant pre-operative CI difference between SC and control group patients (p < 0.00001). In the last two SC repair cases, we attempted concurrent PE prevention or treatment. CONCLUSION: Our findings suggest an underestimated association between PE and SC in the existing literature. SC patients may exhibit a predisposition to PE from birth, which may become more apparent with growth after SC repair. Consequently, PE prevention or treatment should be considered during SC repair procedures.

PURPOSE: In recent years, the use of robotic-assisted minimally invasive surgery in pediatric oncology has increased. Despite its benefits, its adoption remains limited. This single-center retrospective analysis examines technical nuances, indications, and surgical limitations to prevent complications. METHODS: Data from cancer patients treated robotically in 2015-2016 (Group A) and 2020-2022 (Group B) were compared. Decision-making considered tumor characteristics and risks, guided by multidisciplinary tumor board discussions. Data collected included demographics, intra/post-operative details, and tumor classifications. Statistical analysis evaluated influencing factors. RESULTS: Thirty-eight pediatric patients underwent robotic-assisted tumor resection, the median age was 5 years and weight 21.5 kg. Group A had higher median age and weight. Lesions included 23 malignant, 9 borderline, 5 benign cases; neuroblastoma (n = 19) was prevalent procedure and adrenalectomy was the predominant (28.94%). Open conversion occurred in 12 patients (31.58%), mainly due to vascular challenges (23.68%). Intraoperative complications were 10.53%, postoperative 7.9%. About 27% discharged by the third postoperative day; longer stays were needed for complex cases. All resumed post-op chemotherapy as scheduled, and all alive during follow-up. CONCLUSIONS: Our study confirms the safety and efficacy of robotic-assisted tumor resections in pediatric oncology, even during the learning phase, emphasizing the importance of learning curve, patient selection, and trocar positioning.

PURPOSE: Existing guidelines provide weak recommendations on the surgical management of nutritional problems in children. The objective was to design a management pathway to address the best nutritional surgery (NS) procedure in a given patient. METHODS: Retrospective analysis of children treated at our department from January 2015 to December 2019. The sample was divided into two groups according to presence or absence of neurological impairment (NI). Patients with NI (Group 1) were classified in three subgroups based on presenting symptoms: A-Dysphagia without gastroesophageal reflux (GER); B-GER with or without dysphagia; C-Symptoms associated with a delayed gastric emptying. RESULTS: A total of 154 patients were included, 111 with NI. One-hundred-twenty-eight patients underwent only one procedure. Complications and mortality were superior in Group 1. In subgroup A, isolated gastrostomy was the first NS in all patients. In subgroup B most of patients were subjected to a Nissen fundoplication, while in 5 cases total esophagogastric dissociation (TEGD) was the first intervention. Considering the entire sample, 92.3% patients who underwent a TEGD did not require further procedures. CONCLUSION: NS encompasses various procedures depending on presenting symptoms and neurological status. A management flowchart for these patients is proposed.

PURPOSE: To evaluate UDR reliability, sensitivity, specificity and to identify the best treatment basing on UDR among single or double endoscopic injections and ureteral reimplantation. METHODS: Data of patients affected by primary VUR and treated by endoscopic injection over a 10 years period were retrospectively analyzed. Two radiologist attributed reflux grade and UDR on voiding cystourethrogram twice and blinded. Follow-up focused on resolution after 1 or 2 endoscopic injections. Relation between UDR, reflux grade and outcomes were analyzed. RESULTS: Patient enrolled were 198. Low grade VUR was present in 24.8%, grade 3 in 41.6%, grade 4-5 in 33.6%. Resolution after one injection was obtained in 88 patients; among 110 not resolved 104 cases had a second injection. Success after 2 injections was reported in 138 cases. UDR showed a higher reliability compared with reflux grade both in intra than inter-reader measurement (ICC > 90%). Success after 1 or 2 injections was reported for UDR < 0.33 and UDR < 0.47 respectively. CONCLUSION: UDR shows to be a more reliable measurement that allows for an objective estimation of VUR severity and prognosis. It represents a quantitative parameter that might be useful to identify patients who may benefit endoscopic or surgical treatment, avoiding unnecessary under or over-treatment.

Congenital abnormalities of the kidney and urinary tract include a wide range of malformations ranging from asymptomatic to life-threatening conditions. Although pediatric urogenital system imaging is based on the use of US (pre- and postnatal), voiding cystourethrography and scintigraphic study, magnetic resonance (MR) urography plays a fundamental role in the classification and management of congenital abnormalities of the kidney and urinary tract, giving an overview of the different clinical pictures, thanks to its panoramicity and high anatomical detail. In fact the anomalies of the urinary tract are phenotypically variable because they can affect simultaneously several segments of different embryonic derivation, with complex clinical pictures; they can appear both as isolated phenotypes or as complex malformative conditions, involving renal parenchyma, collecting system and bladder. A deep knowledge of this complex embryogenesis and its possible phenotypic patterns allows a correct interpretation of MR urography images. We describe the embryology and pathophysiology of congenital abnormalities of the kidney and urinary tract as well as MR urography technique and findings. Congenital abnormalities of the kidney and urinary tract are classified into four groups: (1) obstruction (proximal, middle and distal), (2) budding with respect to the Wolffian duct (site and number of ureter), (3) ascent and rotation (ectopia, malrotation and fusion of kidney) and (4) anomaly of metanephric differentiation (dysplasia, megapolicalycosis).

BACKGROUND: Hirschsprung disease (HSCR) is a congenital anomaly of the enteric nervous system. Abnormal microbiome composition was reported in HSCR patients. In this study, we addressed and analyzed microbiome modifications with relation tosurgery and HSCR associated enterocolitis (HAEC). METHODS: The faecal microbiome of 31 HSCR patients (overall 64 samples) was analyzed. HAEC was diagnosed and classified according to a combination of Pastor's and Elhalabi's criteria. Stool samples were analyzed by 16S sequencing (7 out of 9 polymorphic regions). Compositional and relative abundance profiles, as well as the functional potentials of the microbial community, were analyzed with the marker gene sequencing profiles using PICRUSt. RESULTS: The relative abundance of Bacteroidetes showed a severe decrease with slow recovery after surgery. Conversely, Proteobacteria transiently increased their abundance. Noteworthy, a strong linkage has been found between Proteobacteria descendants and HAEC occurrences. The inferred functional analysis indicated that virulence factors and fimbriae or pili might be associated with HAEC. CONCLUSIONS: Our study, addressing microbiome dynamics, demonstrated relevant changes after surgical manipulation. Alpha-diversity analyses indicated that surgery deeply affects microbiome composition. Proteobacteria and Enterobacteriaceae seem to play a pivotal role in HAEC occurrences. Several virulence factors, such as fimbriae or pili, might explain the HAEC-predisposing potential of selected microbiomes. These results suggest some innovative therapeutic approaches that deserve to be tested in appropriate clinical trials.

Variants in the ACTG2 gene, encoding a protein crucial for correct enteric muscle contraction, have been found in patients affected with chronic intestinal pseudo-obstruction, either congenital or late-onset visceral myopathy, and megacystis-microcolon-intestinal hypoperistalsis syndrome. Here we report about ten pediatric and one adult patients, from nine families, carrying ACTG2 variants: four show novel still unpublished missense variants, including one that is apparently transmitted according to a recessive mode of inheritance. Four of the remaining five probands carry variants affecting arginine residues, that have already been associated with a severe phenotype. A de novo occurrence of the variants could be confirmed in six of these families. Since a genotype-phenotype correlation is affected by extrinsic factors, such as, diagnosis delay, quality of clinical management, and intra-familial variability, we have undertaken 3D molecular modeling to get further insights into the effects of the variants here described. The present findings and further ACTG2 testing of patients presenting with intestinal pseudo-obstruction, will improve our understanding of visceral myopathies, including implications in the prognosis and genetic counseling of this set of severe disorders.

INTRODUCTION: Since Hirschsprung's disease (HSCR) already proved to benefit from robotic surgery, we aimed at describing a wider series of patients with this rare disease who were operated on with a robotic approach. PATIENTS AND METHODS: All consecutive HSCR patients who underwent totally robotic soave pull-through (TRSPT), between October 2015 and June 2019, have been included. Ethical Committee approval was obtained. Data regarding clinical features, technical details, complications, hospital stay, and functional outcome have been prospectively collected for each patient. RESULTS: Eleven patients have been included. Mean age at surgery was 29 months. Median length of surgery was 420 min. Median console time was 180 min. Six patients suffered from rectosigmoid aganglionosis, three from long HSCR (extending up to the hepatic flexure), two from total colonic aganglionosis. No major intraoperative complications occurred. Four patients (three of whom carrying a stoma) experienced minor mucosal tearing during dissection. One anastomotic stricture required dilatation under general anesthesia and two cuff strictures required cuff release (both occurring in patients who experienced intraoperative mucosal tearing). Follow-up lasted a median of 12 months. One patient experienced mild postoperative enterocolitis. Continence scored excellent-to-good in all patients who could be assessed on that regard (7 out of 11). CONCLUSIONS: Provided a number of technical key points are respected, the outcome of TRSPT for HSCR is promising. Younger patients, particularly those carrying a stoma, proved to be technically demanding and deserve a longer learning curve. Accurate preoperative bowel preparation, correct trocar placement and patient positioning proved to be crucial aspects of treatment. To conclude, TRSPT is particularly suitable for older HSCR patients, even those requiring a redo, and represents a valid alternative to available surgical option for this delicate subgroup of HSCR patients.

BACKGROUND: Restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA) is the recommended elective surgery for children with ulcerative colitis (UC). The aim of this study was to evaluate functional and long-term health-related quality of life (HRQoL) outcomes of surgery in paediatric patients with UC. METHODS: We reviewed the hospital records of all paediatric patients who had undergone surgery for UC between January 2009 and December 2016 in the Units of Paediatric Gastroenterology and Surgery, of both the University Hospital of Messina, and the Gaslini Children's Hospital of Genoa. Surgical treatment was represented by restorative proctocolectomy and laparoscopic IPAA. Patients and parents were interviewed by telephone before and after surgery and responded to the modified IMPACT III questionnaire about health outcomes and HRQoL. The questionnaire was scored on a five-point scale with higher scores indicating a better HRQoL. The total score ranged from 35 (worst HRQoL) to 175 (best HRQoL). RESULTS: Data were obtained in 30 patients (16 males), with a median age of 12 (range 3- 16). The median amount of time elapsed after the operation was 3 years (range 1-4.5). Preoperative scores were very low in all 4 domains of the questionnaire. Postoperatively, HRQoL measures improved significantly (p<0.05), on symptoms, school attendance, social activities, and emotional aspects. Overall, nearly all were completely satisfied with the outcome of surgery. CONCLUSIONS: Our data confirmed that surgical treatment improves the overall HRQoL in paediatric patients with UC.
RESUMO
BACKGROUND: The combination of esophageal atresia, congenital duodenal obstruction, and anorectal malformation has seldom been reported. We describe the largest series of patients with such association, which we summed up with the mnemonic acronym DATE [D-duodenal obstruction, A-anorectal malformation (ARM), and TE-tracheoesophageal fistula with esophageal atresia]. METHODS: This was a multicenter retrospective review of 13 patients recruited from 8 institutions over a nearly 5-decade period (1968-2017). Information gathered included type of DATE malformations, other associated anomalies, type and timing of surgery, and clinical outcomes. RESULTS: The DATE association consisted of type C esophageal atresia (13), complete (9) or incomplete (4) congenital duodenal obstruction (CDO), and high or intermediate (8) or low (5) ARM. Eight patients had at least one additional component feature of VACTERL association. A total of 6 patients died. Overall, 9 patients achieved complete restoration of gastrointestinal continuity, 7 of whom are alive at a median follow-up of 4 y (range, 1 to 9). Survivors received a median of 6 major operations (range, 4 to 14) to overcome their anomalies and surgical complications. Two incomplete duodenal obstructions were initially overlooked. All survivors with high or intermediate ARM defects required some form of bowel management to keep them clean. CONCLUSIONS: The DATE association is a low-frequency entity, often occurring among the wider spectrum of VACTERL association. Functional outcomes largely depend on the severity of ARM or other major associated malformations. Awareness of the DATE association may avoid untoward diagnostic delays of subtler component features of the spectrum, such as an incomplete CDO.

The X-linked alpha thalassemia mental retardation (ATR-X) syndrome is a genetic disorder caused by X-linked recessive mutations in ATRX gene, related to a wide spectrum of clinical manifestations, such as alpha thalassemia, developmental delay, genital abnormalities, and gastrointestinal disorders. Patients with ATR-X syndrome can suffer from different types of epileptic seizures, but a severe epileptic encephalopathy pattern has not been described to date. We describe, for the first time, two brothers with genetically confirmed ATR-X syndrome who presented with drug-resistant epileptic encephalopathy, with tonic and polimorphic seizures reported in the elder brother and epileptic spasms in the younger brother. Moreover, both brothers showed a peculiar movement disorder with myoclonus-dystonia, worsened during periods of distress or pain. These cases expand the clinical spectrum of ATR-X syndrome and open new opportunities for the molecular diagnosis of ATRX mutations in male patients with severe epileptic encephalopathies and movement disorders.

RESUMO
BACKGROUND: Knowing that ureteropelvic junction obstruction is due to a crossing renal vessel is essential in choosing the appropriate surgical treatment. OBJECTIVE: To evaluate the diagnostic accuracy of non-contrast magnetic resonance (MR) angiography in identifying crossing renal vessels in children younger than 4 years old with unilateral hydronephrosis. MATERIALS AND METHODS: A retrospective review of preoperative MR urography of children with unilateral hydronephrosis was conducted by two independent readers. The presence or absence of crossing renal vessels was identified and compared with surgical findings. RESULTS: Twenty-nine patients were included. The disagreement between MR angiography with and without contrast enhancement in detecting a crossing renal vessel was 8%. The disagreement between non-contrast-enhanced MR and surgical findings was 17%. The disagreement between contrast-enhanced MR angiography and surgical findings was 25%. The balanced triggered angiography without contrast enhancement had a sensitivity of 70% (95% confidence interval [CI]: 35-93%) and a specificity of 93% (95% CI: 66-100%). Contrast-enhanced MR angiography had a sensitivity of 56% (95% CI: 21-86%) and a specificity of 91%. (95% CI: 59-100%). CONCLUSION: MR without contrast enhancement may be a reliable, valid and safe alternative to contrast-enhanced MR angiography for identifying crossing renal vessels.

The authors aim to identify criteria for the diagnosis of intestinal visceral myopathy (IVM); results were compared with ultrastructural studies. Six IVM patients and 7 pediatric control cases (without gastrointestinal diseases) were studied. One case was a typical megacystis-microcolon-intestinal hypoperistalsis syndrome. The diagnostic path included: rectal suction biopsy, one-trocar transumbilical laparoscopic intestinal full-thickness biopsy technique. Pathological analysis included anti-alpha smooth muscle actin staining, and US study of intestinal biopsies. IVM histological examination demonstrated thinning of longitudinal muscle layer. The ratio of circular/longitudinal thickness was evaluated in all samples; in cases, this ratio presented as a mean value of 2.91, and in controls, a mean value of 1.472 (Pâ=â0.0002). Ultrastructural diagnosis revealed variable myofibrils density in smooth muscle cells, irregularity of sarcolemma membranes, interstitial fibrosis, and myofiber disarray. The authors concluded that in IVM, circular/longitudinal thickness ratio and alpha smooth muscle actin staining can be used as significant tools to address the diagnosis.

BACKGROUND: Neonatal severe primary hyperparathyroidism (NSHPT) is a rare autosomal recessive disorder of calcium homeostasis, characterized by striking hyperparathyroidism, marked hypercalcemia and hyperparathyroid bone disease. We report the case of a newborn with a novel homozygous mutation of the CaSR, treated by successful subtotal parathyroidectomy, who had an acute presentation of the disease, i.e. out-of hospital cardiorespiratory arrest. . CASE PRESENTATION: A 8-day-old female newborn was admitted to the NICU of University of Bari "Aldo Moro" (Italy) after a cardiorespiratory arrest occurred at home. Severe hypercalcemia was found and different drug therapies were employed (Furosemide, Cinacalcet and bisphosphonate), as well as hyperhydration, until subtotal parathyroidectomy, was performed at day 32. Our patient's mutation was never described before so that a strict and individualized long-term follow-up was started. CONCLUSIONS: This case of NSHPT suggests that a near-miss event, labelled as a possible case of SIDS, could also be due to severe hypercalcemia and evidentiates the difficulties of the neonatal management of NSHPT. Furthermore, the identification of the specific CaSR mutation provides the substrate for prenatal diagnosis.

BACKGROUND: Pilonidal disease is a troublesome acquired condition for whom various surgical treatments have been proposed with relatively high recurrence and complication rates. Since EPSiT technique has been described in 2013, it became an alternative treatment in adult practice. Our study reports the results of a multicentre series of pediatric patients who underwent EPSiT procedure over a 21-month period. METHODS: Between July 2015 and March 2017, all consecutive patients undergoing EPSiT in four different pediatric surgical units have been enrolled. Details regarding demographic data, detailed surgical procedure, outcome and complications have been recorded. RESULTS: A total of 43 patients underwent EPSiT procedure. Mean age was 15 years. There was a slight female preponderance. Mean weight and height at surgery were 67 kg and 168 cm, respectively. In 14% of cases a previous ineffective procedure was performed. Mean length of procedure was 34 min and median hospital stay was 24 h (12-72 h). Median length of follow-up was 4 months (range 3-18 months). Complications leading to reoperation were reported in 9% of cases with an overall resolution rate of 88%. DISCUSSION: EPSiT proved to be feasible and safe even in the pediatric population. The effectiveness and safety of the procedure suggest that this technique can represent a valid alternative for the treatment of pilonidal disease in children.

HSCR is a congenital disorder of the enteric nervous system, characterized by the absence of neurons along a variable length of the gut resulting from loss-of-function RET mutations. Congenital Central Hypoventilation Syndrome (CCHS) is a rare neurocristopathy characterized by impaired response to hypercapnia and hypoxemia caused by heterozygous mutations of the PHOX2B gene, mostly polyalanine (polyA) expansions but also missense, nonsense, and frameshift mutations, while polyA contractions are common in the population and believed neutral. HSCR associated CCHS can present in patients carrying PHOX2B mutations. Indeed, RET expression is orchestrated by different transcriptional factors among which PHOX2B, thus suggesting its possible role in HSCR pathogenesis. Following the observation of HSCR patients carrying in frame trinucleotide deletions within the polyalanine stretch in exon 3 (polyA contractions), we have verified the hypothesis that these PHOX2B variants do reduce its transcriptional activity, likely resulting in a down-regulation of RET expression and, consequently, favouring the development of the HSCR phenotype. Using proper reporter constructs, we show here that the in vitro transactivation of the RET promoter by different HSCR-associated PHOX2B polyA variants has resulted significantly lower compared to the effect of PHOX2B wild type protein. In particular, polyA contractions do induce a reduced transactivation of the RET promoter, milder compared to the severe polyA expansions associated with CCHS+HSCR, and correlated with the length of the deleted trait, with a more pronounced effect when contractions are larger.

BACKGROUND: Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) is gaining worldwide consensus for central venous access in children. This study reports a 20-month experience with this approach in children. METHODS: All patients who underwent percutaneous USG central venous catheter (CVC) positioning in the BCV between August 2013 and March 2015 have been included. Devices inserted during this period were open-ended, either single or double-lumen tunneled CVC. Our series was divided into three consecutive study periods in order to determine the relative incidence of repositioning and complications. RESULTS: During the study period, a total of 95 patients underwent 109 CVC insertions in the BCV. The median length of CVC duration was 230 days for a total of 23,212 catheter days. No major intraoperative complications occurred. Overall rate of CVC-related postoperative complications requiring repositioning or precocious removal was 0.90 per 1,000 catheter days and involved 21 CVC (19%, 95% confidence interval 13-28). These included 18 dislodgments, two infections, and one malfunction. Double-lumen CVCs represented the only significant risk factor for complications (52% complications-three per 1,000 catheter days). CONCLUSION: USG supraclavicular cannulation of the BCV represents a safe approach for central line placement in children. It proved to be versatile, as it can be used in premature infants as well as in adolescents. Provided it is adopted by operators experienced in USG cannulation, we strongly suggest to resort to this approach as a first-line choice in children undergoing tunnelled central line placement for long-lasting therapy.
