RESUMEN
INTRODUCTION: Over the years, congenital lung malformations (CLM) management remains a controversial topic in pediatric thoracic surgery. The Italian Society of Pediatric Surgery performed a national survey to study the current management variability among centers, trying to define national guidelines and a standardized approach of children with congenital lung malformations. METHODS: Following a National Society approval, an electronic survey including 35 items on post-natal management was designed, focusing on surgical, anesthesiology, radiology and pneumology aspects. The survey was conducted contacting all pediatric surgical units performing thoracic surgery. RESULTS: 39 pediatric surgery units (97.5%) participated in the study. 13 centers (33.3%) were classified as high-volume (Group A), while 26 centers (66.7%) were low volume (Group B). Variances in diagnostic imaging protocols were observed, with Group A performing fewer CT scans compared to Group B (p = 0.012). Surgical indications favored operative approaches for asymptomatic CLM and pulmonary sequestrations in both groups, while a wait-and-see approach was common for congenital lobar emphysema. Surgical timing for asymptomatic CLM differed significantly, with most high-volume centers operating on patients younger than 12 months (p = 0.02). Thoracoscopy was the preferred approach for asymptomatic CLM in most of centers, while postoperative long-term follow-up was not performed in most of the centers. CONCLUSION: Thoracoscopic approach seems uniform in asymptomatic CLM patients and variable in symptomatic children. Lack of uniformity in surgical timing and preoperative imaging assessment has been identified as key areas to establish a common national pattern of care for CLM.

Despite advances in their diagnosis and treatment, pediatric cancers remain among the leading causes of death in childhood. The development of immunotherapies and other forms of targeted therapies has significantly changed the prognosis of some previously incurable cancers in the adult population. However, so far, the results in pediatric cohorts are disappointing, which is mainly due to differences in tumor biology, including extreme heterogeneity and a generally low tumor mutational burden. A central role in the limited efficacy of immunotherapeutic approaches is played by the peculiar characteristics of the tumor microenvironment (TME) in pediatric cancer, with the scarcity of tumor infiltration by T cells and the abundance of stromal cells endowed with lymphocyte suppressor and tumor-growth-promoting activity. Thus, progress in the treatment of pediatric solid tumors will likely be influenced by the ability to modify the TME while delivering novel, more effective therapeutic agents. In this review, we will describe the TME composition in pediatric solid tumors and illustrate recent advances in treatment for the modulation of immune cells belonging to the TME.

BACKGROUND: Pediatric robotic-assisted surgeries have increased in recent years; however, guidance documents are still lacking. This study aimed to develop evidence-based recommendations, or best practice statements when evidence is lacking or inadequate, to assist surgical teams internationally. METHODS: A joint consensus taskforce of anesthesiologists and surgeons from the Italian Society of Pediatric and Neonatal Anesthesia and Intensive Care (SARNePI) and the Italian Society of Pediatric Surgery (SICP) have identified critical areas and reviewed the available evidence. The taskforce comprised 21 experts representing the fields of anesthesia (n = 11) and surgery (n = 10) from clinical centers performing pediatric robotic surgery in the Italian cities of Ancona, Bologna, Milan, Naples, Padua, Pavia, Perugia, Rome, Siena, and Verona. Between December 2020 and September 2021, three meetings, two Delphi rounds, and a final consensus conference took place. RESULTS: During the first planning meeting, the panel agreed on the specific objectives, the definitions to apply, and precise methodology. The project was structured into three subtopics: (i) preoperative patient assessment and preparation; (ii) intraoperative management (surgical and anesthesiologic); and (iii) postoperative procedures. Within these phases, the panel agreed to address a total of 18 relevant areas, which spanned preoperative patient assessment and patient selection, anesthesiology, critical care medicine, respiratory care, prevention of postoperative nausea and vomiting, and pain management. CONCLUSION: Collaboration among surgeons and anesthesiologists will be increasingly important for achieving safe and effective RAS procedures. These recommendations will provide a review for those who already have relevant experience and should be particularly useful for those starting a new program.

PURPOSE: To evaluate clinical features at diagnosis, prognostic factors, and outcomes of malignant sacrococcygeal germ cell tumors (SC-GCTs) in patients enrolled in the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) TCG 2004 protocol. PATIENTS AND METHODS: A prospective analysis was conducted on all consecutive patients diagnosed with malignant SC-GCTs between January 2004 and May 2017. Patients with stage I underwent surgery and subsequent surveillance, the others received pediatric cisplatinum-etoposide-bleomycin (pPEB) regimen and eventual deferred surgery. RESULTS: Of 45 patients, 35 were females. Age at diagnosis ranged from 1 day to 3.6 years (median 1.6 years); 26 were stage IV. Of 38 patients who underwent surgery, pathology revealed yolk sac tumor (YST) in 27 and teratoma + YST/embryonal carcinoma in 11, while seven patients were diagnosed based on imaging and elevated levels of alpha-fetoprotein (AFP). Of six patients approached with surgery, only one relapsed and was rescued with first-line chemotherapy. Overall, 38 out of 45 achieved complete remission, three a partial remission, and four were resistant. Ten out of 41 patients who entered remission later relapsed and nine were rescued with a second-line treatment. We observed a global failure percentage of 31% and a 5-year overall survival (OS) and event-free survival (EFS) of 95% and 69%, respectively. CONCLUSIONS: Chemotherapyis generally effective in malignant SC-GCTs, even though almost one-third of our patients experienced events salvageable with second-line treatment. Most of the relapses occurred within 1 year from diagnosis. A close follow up with serial AFP level monitoring should be done for at least 2 years after diagnosis.

PURPOSE: Eosinophilic gastrointestinal disorders are rare in children and present with a broad spectrum of non-specific symptoms. To date, no guidelines for diagnosis, therapy and follow-up are validated. Aim of our study is to focus on eosinophilic colitis (EC), to determine a possible correlation between associated disorders, macroscopic findings and treatment/follow up. METHODS: Retrospective study from 2015 to 2019 including all colonoscopies performed at our Institution. Eosinophilic colitis was defined according to the threshold identified by Collins: > 100 Eo/Hpf: right colon, > 84 Eo/Hpf transverse and left colon, > 64 Eo/Hpf sigma and rectum. We excluded colonoscopy in patients with IBD or other diseases causing hypereosinophilia (i.e., parasite infection, GVHD). RESULTS: Among 399 colonoscopies performed in 355 patients, we made 50 diagnosis of EC, 36 males, 14 females, median age 8.5 (3-17). Symptoms leading to endoscopy were recurrent abdominal pain (66%), chronic diarrhea (64%), and chronic constipation (8%). Two patients presented with GI bleeding and one with weight loss. Macroscopic findings were mostly normal or lymphoid nodular hypertrophy presenting different endoscopic features. In seven children (14%) we found history of allergy and atopy. 22 children present a diagnosis of autistic spectrum disorder (ASD) with a prevalence higher than in the overall population (44% vs 28.5%, p = 0.03). According to symptoms, treatment consist variably of steroids, six food elimination diet, mesalamine. For patients with available follow-up, we found histological persistence of Eosinophils in 75%, even in patients with symptoms relief. CONCLUSION: This study focus attention on EC as a new challenging pathology. Multicentric randomized clinical trials are needed to understand physiopathological mechanisms to validate a possible endoscopic score and related histological threshold, and to standardize therapy according to clinical features and instrumental findings. The high prevalence of EC in ASD need further specific research.

OBJECTIVES: To compare postnatal magnetic resonance imaging (MRI) with the reference standard computed tomography (CT) in the identification of the key features for diagnosing different types of congenital lung malformation (CLM). METHODS: Respiratory-triggered T2-weighted single-shot turbo spin echo (ss-TSE), respiratory-triggered T1-weighted turbo field echo (TFE), balanced fast field echo (BFFE), and T2-weighted MultiVane sequences were performed at 1.5 T on 20 patients prospectively enrolled. Two independent radiologists examined the postnatal CT and MRI evaluating the presence of cysts, hyperinflation, solid component, abnormal arteries and/or venous drainage, and bronchocele. Diagnostic performance of MRI was calculated and the agreement between the findings was assessed using the McNemar-Bowker test. Interobserver agreement was measured with the kappa coefficient. RESULTS: CT reported five congenital pulmonary airway malformations (CPAMs), eight segmental bronchial atresias, five bronchopulmonary sequestrations (BPS), one congenital lobar overinflation, one bronchogenic cyst, and three hybrid lesions. MRI reported the correct diagnosis in 19/20 (95%) patients and the malformation was correctly classified in 22/23 cases (96%). MRI correctly identified all the key findings described on the CT except for the abnormal vascularization (85.7% sensitivity, 100% specificity, 100% PPV, 94.1% NPV, 95% accuracy for arterial vessels; 57.1% sensitivity, 100% specificity, 100% PPV, 84.2% NPV, 87% accuracy for venous drainage). CONCLUSIONS: MRI can represent an effective alternative to CT in the postnatal assessment of CLM. In order to further narrow the gap with CT, the use of contrast material and improvements in sequence design are needed to obtain detailed information on vascularization, which is essential for surgical planning. KEY POINTS: ⢠Congenital lung malformations (CLMs) can be effectively studied by MRI avoiding radiation exposure. ⢠Crucial features of CLM have similar appearance when comparing CT with MRI. ⢠MRI performs very well in CLM except for aberrant vessel detection and characterization.

BACKGROUND: Very limited informations are currently available about the best approach to perform retroperitoneoscopic surgery. This multicentric international study aimed to compare the outcome of lateral versus prone approach for retroperitoneoscopic partial nephrectomy (RPN) in children. METHODS: The records of 164 patients underwent RPN in 7 international centers of pediatric surgery over the last 5 years were retrospectively reviewed. Sixty-one patients (42 girls and 19 boys, average age 3.8 years) were operated using lateral approach (G1), whereas 103 patients (66 girls and 37 boys, average age 3.0 years) underwent prone RPN (G2). The two groups were compared in regard to operative time, postoperative outcome, postoperative complications, and re-operations. RESULTS: The average operative time was significantly shorter in G2 (99 min) compared to G1 (160 min) (p = 0.001). Only 2 lateral RPN required conversion to open surgery. There was no significant difference between the two groups as for intraoperative complications (G1:2/61, 3.3%; G2:6/103, 5.8%; p = 0.48), postoperative complications (G1:9/61, 14.7%; G2:17/103, 16.5%; p = 0.80), and re-operations (G1:2/61, 3.3%; G2:4/103, 3.8%; p = 0.85). Regarding postoperative complications, the incidence of symptomatic residual distal ureteric stumps (RDUS) was significantly higher in G2 (7/103, 6.8%) compared to G1 (1/61, 1.6%) (p = 0.001). Most re-operations (4/6, 66.6%) were performed to remove a RDUS . CONCLUSIONS: Both lateral and prone approach are feasible and reasonably safe to perform RPN in children but the superiority of one approach over another is not still confirmed. Although prone technique resulted faster compared to lateral approach, the choice of the technique remains dependent on the surgeon's personal preference and experience. Our results would suggest that the lateral approach should be preferred to the prone technique when a longer ureterectomy is required, for example in cases of vesico-ureteral reflux into the affected kidney moiety, in order to avoid to leave a long ureteric stump that could become symptomatic and require a re-intervention.

BACKGROUND: Prenatal magnetic resonance imaging is the best tool to visualize foetal airway. OBJECTIVE: To evaluate the performance of MRI in the assessment of foetal airway status in the presence of a neck mass. MATERIALS AND METHODS: Two paediatric radiologists with 12- and 2-year experience in foetal imaging retrospectively analysed 23 foetal MRI examinations, performed between 2001 and 2016, after a second-level ultrasound suspicious for presence of a neck mass. Postnatal imaging, postoperative report, histology, autopsy, and clinical outcomes were the reference standard to calculate sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of prenatal MRI in detecting airway patency. We used the Cohen к statistics to estimate the interobserver agreement. We also assessed MRI performance in the diagnosis of the mass nature. RESULTS: We obtained data about postnatal airway status in 19 of 23 patients; prenatal MRI demonstrated a sensitivity of 9/9 [100%, 95% confidence interval (CI) 66-100%], specificity 8/10 (80%, 44-98%), accuracy 17/19 (89%, 67-99%), PPV 9/11 (82%, 48-98%), and NPV 8/8 (100%, 63-100%); the interobserver agreement was perfect. Prenatal MRI correctly identified 21 of 23 masses (к = 0.858); the interobserver agreement was almost perfect (к = 0.851). CONCLUSION: Prenatal MRI demonstrated high accuracy in assessing foetal airway status and diagnosing mass nature, allowing proper delivery planning.

Monochorionic twins, resulting from a single fertilized egg giving rise to two separate embryos, are monozygotic and considered genetically identical. However, discordant phenotypes have been reported in monozygotic twins. We analyzed a retrospective cohort of 155 monochorionic pregnancies (312 twins) with major discordant structural anomalies coded by the ICD-10 system in order to describe the spectrum of anomalies, the management of the pregnancies, and the perinatal outcome. Treatment options included conservative management, selective feticide with bipolar cord coagulation, or complete termination. All survivors underwent at least 24 months of postnatal follow-up. Discordancy was complicated by twin-to-twin transfusion syndrome in eight pregnancies (5%) and by selective intrauterine growth restriction in 41 (26%). Major structural anomalies affected one system in 139 cases (90%) and multiple systems in 16 (10%). Median gestational age at diagnosis was 19.1 weeks (IQR 16.4-21.3). The most frequent single-system anomalies involved the nervous and circulatory systems. In total, 72 anomalous twins (46%) and 116 normal co-twins (74%) were delivered at a median gestational age of 34.6 weeks (IQR 31.0-36.3). Neonatal/infant death of the anomalous twin occurred in 22 cases (14%), with an overall survival rate of 32% (50/155). Surviving anomalous twins underwent major surgery in 22/50 cases (44%), four of whom (8%) now suffer from severe neurologic morbidity. This study shows that a wide spectrum of major discordant structural anomalies can be found in monochorionic pregnancies. The outcome for the anomalous twin is poor, while the survival rate for the normal co-twin was 71%, with a favorable overall prognosis.

BACKGROUND: Peripheral neuroblastic tumors are the most common extracranial solid neoplasms in children. Early and adequate tissue sampling may speed up the diagnostic process and ensure a prompt start of optimal treatment whenever needed. Different biopsy techniques have been described. The purpose of this multi-center study is to evaluate the accuracy and safety of the various examined techniques and to determine whether a preferential procedure exists. METHODS: All children who underwent a biopsy, from January 2010 to December 2014, as a result of being diagnosed with a peripheral neuroblastic tumor, were retrospectively reviewed. Data collected included patients' demographics, clinical presentation, intraoperative technical details, postoperative parameters, complications, and histology reports. The Mann-Whitney U and Fisher's exact tests were used for statistical analysis. RESULTS: The cohort included 100 patients, 32 of whom underwent an incisional biopsy (performed through open or minimally invasive access) (Group A), and the remaining 68 underwent multiple needle-core biopsies (either imaging-guided or laparoscopy/thoracoscopy-assisted) (Group B). Comparing the two groups revealed that Group A patients had a higher rate of complications, a greater need for postoperative analgesia, and required red blood cell transfusion more often. Overall adequacy rate was 94%, without significant differences between the two groups (100% vs. 91.2% for Group A and Group B, respectively, P = 0.0933). CONCLUSIONS: Both incision and needle-core biopsying methods provided sub-optimal to optimal sampling adequacy rates in children affected by peripheral neuroblastic tumors. However, the former method was associated with a higher risk of both intraoperative and postoperative complications compared with the latter.

BACKGROUND: Gastrointestinal (GI) carcinomas are very rare in the pediatric and adolescent age range. We report the clinical features, treatment, and outcome of a series of children and adolescents with GI carcinoma prospectively registered in the Italian Tumori Rari in Età Pediatrica (TREP) project. METHODS: The TREP project developed diagnostic and therapeutic guidelines based on recommendations currently in use for adults. Clinical data were centrally registered and reviewed. RESULTS: Fifteen patients were registered over the years 2000-2016. Most of the tumors were colorectal carcinomas (12 cases). All but one patient had advanced-stage disease (American Joint Committee on Cancer stages III-IV), and the majority of patients had aggressive histological subtypes, i.e. poorly differentiated (G3) (five patients), mucinous (four patients), and signet ring (two patients) adenocarcinomas. Surgery was performed in 13 of 15 patients, and was radical in nine of 13 patients. Only one patient received postoperative radiotherapy. All patients received chemotherapy, with the addition of bevacizumab in two cases. Nine patients were still alive at the time of the present report, but two of them had only just completed their treatment program and one patient is still on treatment. Six patients died due to disease progression. CONCLUSIONS: This prospective report on pediatric GI tract carcinomas confirms the rarity and biological aggressiveness of these diseases in pediatric and adolescent age. Further prospective studies are needed to explore the distinct biology of tumor in this age group in order to find new therapeutic targeted agents.

PURPOSE: To compare the outcome of laparoscopic and retroperitoneoscopic approach for partial nephrectomy in infants and children with duplex kidneys. METHODS: Data of 102 patients underwent partial nephrectomy in a 5-year period using MIS procedures were analyzed. Fifty-two children underwent laparoscopic partial nephrectomy (LPN), and 50 children underwent retroperitoneoscopic partial nephrectomy (RPN). Median age at surgery was 4.2 years. Statistical analysis was performed using χ (2) test and Student's t test. RESULTS: The overall complications rate was significantly higher after RPN (15/50, 30 %) than after LPN (10/52, 19 %) [χ (2) = 0.05]. In LPN group, complications [4 urinomas, 2 symptomatic refluxing distal ureteral stumps (RDUS) and 4 urinary leakages] were conservatively managed. In RPN group, complications (6 urinomas, 8 RDUS, 1 opening of remaining calyxes) required a re-operation in 2 patients. In both groups no conversion to open surgery was reported. Operative time (LPN:166.2 min vs RPN: 255 min; p < 0.001) and hospitalization (LPN: 3.5 days vs RPN: 4.1 days; p < 0.001) were significantly shorter in LPN group. No postoperative loss of renal function was reported in both groups. CONCLUSIONS: Our results demonstrate that RPN remains a technically demanding procedure with a significantly higher complications and re-operation rate compared to LPN. In addition, length of surgery and hospitalization were significantly shorter after LPN compared to RPN. LPN seems to be a faster, safer and technically easier procedure to perform in children compared to RPN due to a larger operative space and the possibility to perform a complete ureterectomy in refluxing systems.

BACKGROUND: One-trocar laparoscopic appendectomy (OTA) is routinely adopted in children with acute appendicitis. In case of a difficult appendectomy, it is necessary to add additional trocar/s to safely complete the procedure. This technique is called multiport hybrid laparoscopic appendectomy (HLA). We aimed to compare the outcome of multiport HLA versus OTA. METHODS: We retrospectively reviewed the data of 1,092 patients underwent LA in 5 European centers of pediatric surgery in the last 5 years. We compared 2 groups: G1 of 575 patients (52.6 %) (average age 10 years) underwent OTA and G2 of 517 patients (47.4 %) (average age 8.2 years) underwent multiport HLA. RESULTS: No intra-operative complications occurred in both groups. An additional pathology was treated in 12 cases (8 Meckel's diverticulum, 2 carcinoids, 2 ovarian cysts) in G2. Operative time was significantly shorter in G2 compared to G1 (47.8 vs 58.6 min; p < .001). The average analgesic requirement was significantly shorter in G2 compared to G1 (44 vs 56 h; p < .001). As for postoperative complications, the incidence of port-site infections was similar between the two groups, while the incidence of postoperative abdominal abscesses (PAA) was significantly higher in G1 compared to G2 (4.7 vs 0.2 %; p < .001). The cosmetic outcome was excellent in all patients of both groups. A subgroup analysis between complicated and uncomplicated appendicitis showed that only in complicated cases, the average operative time, the average VAS pain score, the average analgesic requirements and the incidence of PAA were significantly higher in OTA group compared to multiport HLA group (p < .001). CONCLUSIONS: Our results suggest that OTA is a valid and safe procedure for the uncomplicated cases, while additional trocars are required in case of complicated appendicitis. Multiport HLA significantly reduces the operative time, the incidence of abdominal abscesses and the analgesic requirements compared to OTA.

BACKGROUND: Teratomas demonstrate a benign clinical behavior, however they may recur with malignant components or as teratoma, and in a small group of patients prognosis could be fatal. After the first Italian study, we collected cases of teratoma, alongside the protocol for malignant germ cell tumors. PROCEDURE: Patients with teratoma were collected from 2004 to 2014. Teratomas were classified according to the WHO classifications, as mature and immature. Patients with pathological aFP and/or bHCG, and those with a malignant germ cell component were not included. RESULTS: The study enrolled 219 patients (150 mature, 69 immature teratomas) with a median age at diagnosis of 42 months. The primary sites involved were: 118 gonadal and 101 extragonadal teratomas. Two females with ovarian teratoma had a positive family history. Complete and incomplete surgeries were performed in 85% and 9% of cases. Seventeen events occurred: six females had a second metachronous tumor (5 contralateral ovarian teratoma, 1 adrenal neuroblastoma) and 11 teratomas relapsed/progressed (3 mature, 8 immature teratomas). Two patients died, one of progressive immature teratoma and one of surgical complications. At a median follow up of 68 months, the event-free, relapse-free, and overall survival rates were 90.6%, 94.3%, 98.6%, respectively. CONCLUSIONS: Teratomas show a good prognosis, especially the mature ones: surgery and follow-up remain the standard approach. Incomplete surgery in immature teratoma is the group at greatest risk of relapse. Bilateral ovarian tumors are a possibility, and the rare family predisposition to ovarian mature teratoma warrants further analyses.

PURPOSE: Surgeons are at risk for developing work-related musculoskeletal symptoms (WMS). The present study aims to compare laparoscopy and SILS ergonomy among pediatric surgeons. METHODS: A questionnaire formed by 17 questions was mailed to 14 pediatric surgeons, seven with a large experience in laparoscopy and seven in SILS. All surgeons completed the survey. The questionnaires were focused on the type of laparoscopic or SILS activity, location and type of pain, need for drugs and its physical consequences. Results were analyzed using χ(2) test. RESULTS: Results indicated a similar incidence of WMS with shoulder symptoms (>75%) in both groups. In laparoscopic group this pain is evident only after a long lasting procedure, while in SILS group the pain is present after each procedure performed. SILS surgeons used painkillers and other therapies statistically more frequently than laparoscopic group (χ(2) = 0.001). CONCLUSIONS: This study confirms there is a strong association between WMS and MIS surgery. The incidence of pain is similar in both groups. Pain was present only after long lasting procedures in laparoscopic group, while SILS surgeons have pain after each procedure performed. In addition SILS surgeons use more frequently painkillers and other therapies compared to laparoscopic surgeons. In conclusion, it seems that SILS has a worse ergonomy compared to laparoscopy.

Background: Structured light plethysmography (SLP) is a novel light-based method that captures chest wall movements to evaluate tidal breathing. Methods: Thirty-two children who underwent lung surgery were enrolled. Their clinical history was collected along with spirometry and SLP. Results: Median age of surgery was 9 months (interquartile range 4-30). Most frequent diagnosis was congenital pulmonary airway malformation (14/32), then pulmonary sequestration (9/32), tumor (5/32), and bronchogenic cyst (4/32). The most frequent surgical approach was lobectomy (59%), segmentectomy (38%), and complete resection (3%). More than 80% had surgery when younger than 3 years of age. Eight patients had short-term complications (pleural effusion was the most frequent), while long-term effects were reported in 15 patients (19% recurrent cough, 13% thoracic deformities, 13% airway infections, 9% wheezing, 6% reduced exercise tolerance, and 3% columnar deformities). Spirometry was normal in 9/22 patients. Nine patients had a restrictive pattern, while 4 showed a mild bronco-reactivity. Ten patients did not perform spirometry because of young age. SLP revealed the presence of obstructive pattern in 10% of patients (IE50 > 1.88) and showed a significant difference between the two hemithorax in 29% of patients. Discussion: SLP may be a new method to evaluate lung function, without collaboration and radiation exposure, in children who underwent lung resection, also in preschool age.

Breast implants are extensively employed for both reconstructive and esthetic purposes. However, the safety of breast implants with textured surfaces has been questioned, owing to a potential correlation with anaplastic large-cell lymphoma and the recurrence of breast cancer. This study investigates the immune response elicited by different prosthetic surfaces, focusing on the comparison between macrotextured and microtextured breast implants. Through the analysis of intraoperatively harvested periprosthetic fluids and cell culture experiments on surface replicas, we demonstrate that macrotextured surfaces elicit a more pronounced chronic-like activation of leucocytes and an increased release of inflammatory cytokines, in contrast to microtextured surfaces. In addition, in vitro fluorescent imaging of leucocytes revealed an accumulation of lymphocytes within the cavities of the macrotextured surfaces, indicating that the physical entrapment of these cells may contribute to their activation. These findings suggest that the topography of implant surfaces plays a significant role in promoting a chronic-like inflammatory environment, which could be a contributing factor in the development of lymphomas associated with a wide range of implantable devices.

BACKGROUND: Congenital h-type tracheoesophageal fistula (H-TEF) without esophageal atresia (EA) represents about 4% of congenital esophageal anomalies. The diagnosis is challenging, and surgery is considered curative. The aim was to report a national survey on the diagnosis, management, and outcome of patients with congenital H-TEF. METHODS: Following approval of the Italian Society of Pediatric Surgery, a survey was sent to all Pediatric Surgery Units to retrospectively collect H-TEF treated in the period 2010-2022. Descriptive analysis was performed, and results are given as prevalence, mean ± standard deviation (SD), or median and interquartile range (IQR). RESULTS: The survey was sent to 65 units. Seventeen responded with one or more cases; 78 patients were diagnosed with H-TEF during the study period. Associated malformations were present in 43%, mostly cardiac (31%). The most frequent symptoms were cough (36%), bronchopneumonia (24%), and dysphagia (19%). H-TEF was detected by tracheobronchoscopy (90%), and/or upper GI (58%), and/or esophagoscopy (32%). The median age at diagnosis was 23 days (1 day-18 years). The most common approach was cervicotomy (76%), followed by thoracoscopy (14%) and thoracotomy (9%). The fistula underwent ligation and section of the fistula in 90% of the patients and clip closure and section in 9%. In one patient, the fistula was cauterized endoscopically. H-TEF preoperative cannulation was performed in 68% of cases, and a drain was placed in 26%. One month after surgery, 13% of the patients had mild persisting symptoms, mainly hypophonia. Recurrence occurred in 5%, and a second recurrence occurred in 1%. CONCLUSIONS: H-TEF prevalence was six cases/year, consistent with the expected rate of five cases/year in our country. The diagnosis was challenging, sometimes delayed, and, in most patients, required multiple examinations. Fistula ligation and section through cervicotomy were the most frequent treatment. Long-term outcomes are good, and recurrence is a rare event.
RESUMEN
BACKGROUND: Pediatric renal cancer survivors have higher rate of chronic renal disease and hypertension. These patients have similar survival rates when treated according to either Children's Oncology Group (COG) or International Society of Pediatric Oncology (SIOP) protocols. We aimed to compare the late outcome of these two approaches. METHODS: We performed a meta-analysis of all studies from 2000 to 2021; database search using keywords: long-term outcomes OR late effects, nephrectomy, pediatric renal cancer. For each protocol, data were collected, and the "pooled" outcomes were compared. Continuous and dichotomous variables were obtained with a 95% odds ratio. RESULTS: Sixteen studies with a total of 715 pediatric renal cancer survivors were analyzed. The mean follow-up time was 17.4 (standard deviation 5.6) years. Reduced renal function and hypertension were the most encountered long-term complications. The mean estimated glomerular filtration rate was similar in both protocols (101.62 vs. 101.70 mL/min/1.73 m2), while the prevalence of hypertension was 23% in COG and 10% in SIOP. The prevalence of secondary malignancy was 1.1% in COG and 6.7% in SIOP (1.1% vs. 6.7%, p ≤ 0.001). Chronic kidney disease was similar in both groups. CONCLUSION: A high prevalence of hypertension was observed among pediatric renal cancer survivors, as well as an increased risk of a secondary tumor. These results emphasize the importance of long-term follow-up into adulthood, to promptly diagnose any long-term side effects of the treatment. Thanks to the increased overall survival, future protocols will pay attention to the reduction of long-term sequelae.
