Congenital lung malformations: a nationwide survey on management aspects by the Italian Society of Pediatric Surgery.

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.

Magnetic foreign body ingestion in pediatric age.

OBJECTIVES: To assess the clinical complications reported after the ingestion of magnetic foreign bodies (FBs) in pediatric age, along with their incidence among all FB ingestions and clinical presentation. STUDY DESIGN: We've consecutively recruited all children aged 0-14 years who were admitted for single or multiple magnet ingestion from May 2015 to December 2022. Patient demographics, admission sources and discharge status were accurately recorded, along with their clinical management and outcomes. RESULTS: Sixty-one children were enrolled, of whom 49/61 (80.3%) had ingested a single magnet and 12/61 (19.7%) multiple magnets. Only 1/49 children with single magnet required endoscopic removal due to esophageal retention. Among children having ingested multiple magnets, 5/12 (41.7%) undergo endoscopic removal since magnets were amenable to endoscopic retrieval whereas in 7/12 (58.3%) magnets could not be promptly removed. Among these, 4/12 (33.3%) later developed intestinal ischemia/necrosis or perforation and required FB surgical intervention whereas 3/12 (25%) uneventfully evacuated magnets. CONCLUSIONS: Our data confirm that multiple magnet ingestion, unlike single magnet ingestion, pose a serious health hazard. Parents and caregivers should remove them from the reach of children. Medical providers should maintain a high index of suspicion of their ingestion since prompt evaluation and likely removal may be lifesaving and intestine saving.

Early diagnosis of Meigs syndrome in children A case report and a review of the literature.

Meigs syndrome is a rare disease defined by the coexistence of benign ovarian neoplasm, ascites and hydrothorax, which mainly affects women over the age of 30. This clinical condition refers only to cases in which the ovarian neoformation is a fibroid, a thecoma, a granulosa cell tumor or a Brenner tumor with disappearance of symptoms and effusions after removal of the neoplasm. Meigs syndrome is most frequently characterized by the presence of an ovarian fibroid, which in childhood is very rare and not commonly associated with the disease. In this article we report the case of an 11- year-old girl who came to our observation for a high fever for five days accompanied by cough and abdominal pain; imaging methods revealed bilateral hydrothorax, ascites, and a voluminous expansive right ovarian formation. On histological examination, the mass showed a cellular fibroid and the diagnosis of Meigs syndrome was made. Furthermore, we present a review of the literature aimed at detecting the state of knowledge on this disease in pediatric age, giving particular emphasis to the condition for which, in the presence of pleural effusion and ascites, an ovarian neoformation is not necessarily malignant. KEY WORDS: CT, Meigs syndrome, Pediatric, Pelvic mass, Ultrasounds.

Prenatal detection of megacystis: not always an adverse prognostic factor. Experience in 25 consecutive cases in a tertiary referral center, with complete neonatal outcome and follow-up.

INTRODUCTION: Megacystis is a condition of abnormal enlarged fetal bladder for gestational age, which is usually associated with urological malformations that may constitute a life-threatening condition for the baby. OBJECTIVE: The purpose of this study was to assess the prognostic and etiological criteria of fetal megacystis and to describe the neonatal outcome in a large series collected in a single tertiary center. STUDY DESIGN: A retrospective observational study was conducted between 2008 and 2012. We reviewed all consecutive cases of fetal megacystis diagnosed during routine ultrasound (US) screening. The following data were collected and analyzed: maternal age, gestational age at diagnosis, prenatal ultrasonographic details of the urinary system, extra-urinary ultrasonographic anomalies, fetal karyotype, pregnancy outcome, postnatal diagnosis, and medical/surgical follow-up. RESULTS: Of the 25 fetuses included in this study, 76% were males. The mean gestational age (GA) at diagnosis was 23.1 ± 7.5 weeks (range 12-34), among them only four (16%) were diagnosed during the first trimester. Associated urological malformations were detected in 92% (n = 23) of the cases, while other malformations were detected in 36% (n = 9). Oligohydramnios or anyhydramnios were observed in 52% (n = 13) of the cases. Twelve (48%) fetuses were considered as having poor prognosis for renal function. Vesicocentesis with or without vesico-amniotic infusion were performed in 28% (n = 7) of the cases. Pregnancy outcome was surprisingly good, with only one case of prenatal death and survival rate of 96% (n = 24) of liveborn babies. Posterior urethral valve (PUV) (n = 9, 36%) was the most common etiology of the fetal megacystis, followed by persistent urogenital sinus (n = 2, 8%), Prune belly syndrome (n = 2, 8%) and bilateral vescico-ureteral reflux (VUR) (n = 2, 8%). Surgical or endoscopic procedures were performed in 75% (n = 18) of the cases. Six (24%) newborns presented with moderate/severe respiratory distress that requested invasive assisted ventilation. Three cases (n = 3, 12%) of perinatal death were observed due to severe impaired renal function. After a median follow-up of 29 months renal function was good in 79% (n = 19) of the cases. CONCLUSIONS: Fetal megacystis may underline a wide range of associated pathologies with the highest prevalence of urinary malformation. Optimal counseling of the involved parents requires a multidisciplinary approach to allow the best management during the pregnancy and the perinatal period. Despite the high risk of renal failure, lung hypoplasia, and severe associated anomalies, the outcome of fetuses with megacystis could be improved thanks to an appropriate perinatal diagnosis and neonatal management.
