RESUMEN
BACKGROUND: Children undergoing diagnostic and interventional radiology procedures often require sedation to achieve immobility and analgesia if the procedure is painful. In the past decades, leading scientific organizations have developed evidence-based guidelines for procedural sedation and analgesia in children outside of the operating room. Their recommendations are being applied to procedural sedation in radiology. However, some questions remain open regarding specific aspects contextualized to the radiology setting, such as elective prone sedation, the urgency of the procedure, when venous access or airway protection is required, and others. AIMS: To address the unresolved issues of procedural sedation and analgesia in pediatric diagnostic and interventional radiology. METHODS: An expert panel of pediatricians, pediatric anesthesiologists, intensivists, and neuroradiologists selected topics representative of current controversies and formulated research questions. Statements were developed by reviewing the literature for new evidence, comparing expertise and experience, and expressing opinions. Panelists' agreement with the statements was collected anonymously using the DELPHI method. RESULTS: Twelve evidence-based or expert opinion incorporate are presented, considering risks, benefits, and applicability. CONCLUSIONS: This consensus document, developed by a multidisciplinary panel of experts involved in the field, provides statements to improve the quality of decision-making practice in procedural sedation and analgesia in pediatric radiology.
RESUMEN
BACKGROUND/PURPOSE: In neutropenic children with hematologic malignancies, the optimal timing of implanted central venous catheter (ICVC) insertion is unclear. The policy in our Institution has been to place ICVC at the time of diagnosis of disease regardless of the absolute neutrophil count. The impact of this strategy on the incidence of ICVC removal within 30 days of placement was evaluated in a series of patients. Other possible risk factors for ICVC early removal were also examined. MATERIALS AND METHODS: Records of all children with hematologic malignancies who underwent placement of ICVC during 2007 to 2010 were reviewed. The incidence of catheter-related complications and early removal was compared between subjects who were neutropenic at the time of ICVC placement and those who had a normal absolute neutrophil count. RESULTS: An ICVC was placed in 117 children, and only in 12 (10.2%) children it was removed within 30 days. However, the incidence of complications and removal was not influenced by the presence of neutropenia. Only an age below 2 years was demonstrated to be a risk factor for early complication and removal. CONCLUSIONS: The policy to place ICVC in neutropenic patients has been reasonably safe, in our hands. Meticulous preoperative evaluation, the accurate surgical technique and considerable care in their postoperative management are essential to prevent complications, especially in newborns and infants, who seem to be at greater risk of ICVC removal.

BACKGROUND: There is very few information regarding pain after craniotomy in children. OBJECTIVES: This multicentre observational study assessed the incidence of pain after major craniotomy in children. METHODS: After IRB approval, 213 infants and children who were <10 years old and undergoing major craniotomy were consecutively enrolled in nine Italian hospitals. Pain intensity, analgesic therapy, and adverse effects were evaluated on the first 2 days after surgery. Moderate to severe pain was defined as a median FLACC or NRS score ≥ 4 points. Severe pain was defined as a median FLACC or NRS score ≥ 7 points. RESULTS: Data of 206 children were included in the analysis. The overall postoperative median FLACC/NRS scores were 1 (IQR 0 to 2). Twenty-one children (16%) presented moderate to severe pain in the recovery room and 14 (6%) during the first and second day after surgery. Twenty-six children (19%) had severe pain in the recovery room and 4 (2%) during the first and second day after surgery. Rectal codeine was the most common weak opiod used. Remifentanil and morphine were the strong opioids widely used in PICU and in general wards, respectively. Longer procedures were associated with moderate to severe pain (OR 1.30; CI 1.07-1.57) or severe pain (OR 1.41; 1.09-1.84; P < 0.05). There were no significant associations between complications, pain intensity, and analgesic therapy. CONCLUSION: Children receiving multimodal analgesia experience little or no pain after major craniotomy. Longer surgical procedures correlate with an increased risk of having postoperative pain.

INTRODUCTION: Vascular complications are severe complications of pediatric kidney transplantation (KT). We aimed to investigate whether a complex bench surgery (BS) affects the outcomes. METHODS: All pediatric KT performed at the University Hospital of Padua from 2015 to 2019 were analyzed, comparing those in which a standard BS was possible to those that necessitated a complex BS. The rates of vascular complications, patients' outcome, and graft survival were compared in the two groups. RESULTS: Eighty KTs were performed in 78 patients with a median age of 11 years (interquartile range [IQR] 4.3-14) and a median body weight of 24 kg (IQR 13-37). Thirty-nine donor kidneys (49%) needed a complex BS due to anomalies of renal veins in 12 (31%) and renal arteries in 16 (41%). The remaining 11 grafts (28%) underwent an elongation of the vein. There was no difference in the rate of primary graft non function (p = 0.97), delayed graft function (p = 0.72), and overall survival (p = 0.27). The rates of vascular complications, bleedings, and venous graft thrombosis were similar (p = 0.51, p = 0.59, p = 0.78, respectively). No arterial thrombosis or stenosis was reported. CONCLUSION: Complex BS did not compromise survival of the graft and did not put the allograft at risk of vascular complications, such as bleedings or thrombosis.

OBJECT: Although a rarely reported occurrence, late failure of endoscopic third ventriculostomy (ETV) may occur in children as a result of a variety of factors. Delay in recognition of symptoms can lead to harmful deterioration in the patient's condition. The authors undertook this study to assess the capacity of cine phase-contrast MR imaging to identify late failure in asymptomatic pediatric patients treated with ETV for hydrocephalus. METHODS: This study was a retrospective evaluation of cases involving patients who underwent ETV between January 1, 1999, and December 31, 2008, at the pediatric neurological surgery service of the University of Padua. Before 2004, patients were routinely followed up with cine MR imaging at 3, 6, and 12 months after ETV. In 2004, a protocol of annual cine MR follow-up was instituted as a result of a case of fatal late failure. The authors evaluated all cases of late failure identified through cine MR imaging and performed a statistical analysis to investigate the relationship between ETV failure and several variables, including the cause of hydrocephalus for which ETV was originally indicated. RESULTS: In a series of 84 patients (age range 6 days-16 years), 17 patients had early ETV failure. Of the remaining 67 patients, 5 (7%) were found to have no CSF flow through the fenestration and recurrent ventriculomegaly when assessed with cine MR imaging at 1, 2, 3, 4, and 7 years after ETV. The patient in whom ETV failure was identified 1 year postoperatively had Dandy-Walker malformation. The patients in whom ETV failure was identified 2, 3, and 4 years postoperatively all had undergone ETV for treatment of postinfective hydrocephalus. The patient in whom ETV failure was identified 7 years postoperatively had a cystic arachnopathy in the fourth ventricle after cerebellar astrocytoma removal. CONCLUSIONS: Patients who undergo ETV for infective hydrocephalus and Dandy-Walker malformation should receive long-term follow-up, because late closure of the stoma may occur progressively and slowly. Intraoperative observation of thickened arachnoid membranes at the level of the interpeduncular cisterns at the first ETV and a progressive decreasing of CSF flow through the stoma on routine cine MR imaging should be considered unfavorable elements entailing a significant risk of deterioration.

Vaginal strictures are rare entities in pediatric population, mainly due to congenital genito-urinary tract malformations and sequelae of their surgical treatment, recurrent vaginitis and multisciplinary therapy for malignant tumors. The therapy of choice is not standardized. Conservative treatments are favored and dilators seem to be very effective, but their use in children is difficult due to poor compliance. We report our experience with topical application of mitomycin-C in a female with vaginal stricture secondary to brachytherapy.

Despite improvements in prenatal diagnosis and neonatal intensive care, the Congenital Diaphragmatic Hernia (CDH) Registry still records a 64% survival rate. Many reports demonstrate, however, that approximately 80% of CDH patients with no other malformations may survive if managed with permissive hypercapnia, gentle ventilation, high-frequency oscillatory ventilation (HFOV), surfactant, inhaled nitric oxide (iNO) and extracorporeal membrane oxygenation (ECMO), and delayed surgical repair. We wished to define the evolving outcome of CDH newborns using a protocol approach to management, which includes surgery in the neonatal intensive care unit (NICU) or operating room (OR). From January 1996, data were collected prospectively on 42 consecutive live-born infants with CDH. Newborns symptomatic at birth were sedated and paralyzed in the delivery room, and treated with elective HFOV, iNO, surfactant, and ECMO as necessary, delaying surgical repair until their clinical conditions were stable. Once the CDH newborn was stabilized, a trial on conventional ventilation was started at least 24 hours before surgery; however, if the patient was unstable, therapy was switched back to HFOV and surgery was performed in the NICU. Demographic and clinical parameters were compared between CDH newborns who underwent surgery in the NICU and in the OR. The two groups were comparable in terms of clinical characteristics and baseline ventilatory and blood gas values. Mean age at surgery was 3 +/- 2 days. After surgery, the NICU group had more infectious complications. However, the survival rate of uncomplicated CDH was 78% and a low rate of chronic lung disease was reported. A prolonged phase of presurgery stabilization is proposed and strict control of infection is recommended for the CDH newborns who might benefit from an exclusive HFOV and NICU surgery.

BACKGROUND: A retrospective study was performed to evaluate whether pretreatment with erythropoietin and iron combined with acute preoperative normovolaemic haemodilution (APNH) could decrease homologous blood transfusion in craniosynostosis (CS) surgery. A treated group was compared with a historical group of infants who underwent surgery with no pretreatment. METHODS: The charts of 25 healthy infants who underwent CS surgery were reviewed. Nine of them underwent surgery with no treatment beforehand. Sixteen infants were given erythropoietin at a dosage of 300 U.kg -1 two times per week and iron (elemental iron 10 mg.kg-1.day-1) for 3 weeks before surgery. On the day of surgery APNH was performed after induction of general anaesthesia; a precalculated amount of autologous blood was withdrawn and replaced by hydroxyethyl starch 6%. RESULTS: Eleven of the 16 infants of the study group received only autologous blood. Five of 16 received homologous blood transfusion vs seven of nine infants in the control group. CONCLUSIONS: APNH combined with erythropoietin was effective in reducing homologous blood requirements during CS surgery. Further studies are necessary on a larger scale to assess the role of this technique in avoiding homologous blood transfusion and to evaluate how infants can benefit from this combined approach.

In animal CDH models, surfactant deficiency contributes to the pathophysiology of the condition but information on human disease is very limited. The aim of our study was to investigate surfactant kinetics in CDH newborns. We studied surfactant disaturated-phosphatidylcholine (DSPC) half-life, turnover and apparent pool size by stable isotope methodology in CDH newborns with no ExtraCorporeal Membrane Oxygenation (ECMO) support (n = 13, birth weight (BW) 3.2 +/- 2.2 kg, gestational age (GA) 39 +/- 0.4 wks, postnatal age 43 +/- 11 h) and in 8 term infants with no lung disease (CONTROLS, BW 2.7 +/- 0 kg, GA 38 +/- 0.8 wks, postnatal age 96 +/- 26 h). We administered a trace dose of 13C-palmitic acid dipalmitoyl-phosphatidylcholine (DPPC) through the endotracheal (ET) tube and we measured DSPC kinetics by gas chromatography-mass spectrometry from DSPC13C-enrichment decay curves obtained from sequential tracheal aspirates. DSPC amount from tracheal aspirates (TA-DSPC) was measured by gas chromatography. In CDH infants DSPC half-life was shorter (24 +/- 4 and 53 +/- 11 h, p = 0.01), turnover faster (0.6 +/- 0.1 and 1.5 +/- 0.3 d-1 p = 0.01), apparent pool size smaller (34 +/- 6 and 57 +/- 7 mg/kg body weight, p = 0.02) and tracheal aspirates DSPC amount lower (2.4 +/- 0.4 and 4.6 +/- 0.5 mg/mL Epithelial Lining Fluid (ELF), p = 0.007) than in CONTROLS. In conclusion surfactant kinetics is grossly abnormal in mechanically ventilated CDH. Whether alterations of DSPC kinetics in CDH infants are caused by a primary surfactant deficiency or are secondary to oxygen therapy and ventilator support has still to be determined.
