Abstract
Background
Teratoma is a tumor derived from fetal germ cells with aberrant differentiation.
Case Description
A 3-month-old infant with a mediastinal tumor was referred to our heart center. She presented with progressive dyspnea, cyanosis, and the need to be manually ventilated. The computed tomography scan displayed a huge tumor restricting the distal trachea including the bifurcation. An emergent operation was performed and the tumor was completely removed. Histological examination confirmed a mature teratoma.
Conclusion
In such life-threatening situation, the early detection and the immediate operation are very important for the management of rapidly-progressing mediastinal teratomas compressing the respiratory tract.

Abstract
Pulmonary pneumatoceles were relatively common in neonates in the pre-surfactant era. In the current era of surfactant, noninvasive and gentle invasive ventilation there is a paucity of data on clinical characteristics and outcomes of pneumatoceles in neonates. The lesion generally resolves spontaneously, but a few cases follow a complicated course with formation of extensive and expanding lesions. To better understand the pathophysiology, clinical significance, natural history, complications, treatment options and prognosis of pulmonary pneumatoceles in neonates, an extensive research was performed on the databases of medical literature. The information collected in this review is important for the clinicians in decision-making, especially in the most difficult cases.

Abstract
Abstract
Background: While teratomas account for the leading cause of germ cell tumors, the mediastinal teratomas represent one of the infrequent types of congenital germ cell tumors. Neonates with large mediastinal teratomas generally show severe respiratory distress, and the immediate surgical treatment is needed to alleviate their problems.
Objectives: Report clinical symptoms, diagnostic procedures, treatment option, and outcomes after the treatment for a neonate with a large mediastinal teratoma.
Methods: A 2-day-old female infant presented with acute respiratory failure diagnosed as mediastinal teratoma. It was followed with surgical treatment. The removed tissues were examined pathologically.
Results: The girl suffered an acute respiratory failure two days after birth. The chest radiography, echocardiography, and chest computerized tomography results showed the considerable size of the mediastinal teratoma. A median sternotomy was performed on the third day of infant life to remove the tumor without rupturing the capsule. Pathological diagnosis was germ cell tumor. Clinical follow-ups reported no complication.
Conclusion: The successful management of a neonate with large mediastinal teratomas was presented. Immediate detection and proper treatment of the large mediastinal teratoma in a neonate was most important to decrease the morbidity and mortality of the infant.

Abstract
INTRODUCTION The appropriate management of asymptomatic congenital pulmonary malformations (CPMs) remains controversial. Prophylactic surgery is recommended to avoid the risk for development of pulmonary infections and to prevent the highly debated development of malignancy. However, the true risk for development of malignancy remains unknown. A systematic review analyzed all cases in which lung tumors associated with CPMs in both the pediatric and adult populations were described. METHODS A comprehensive literature search was carried out; it included all the cases in which an association between CPMs and malignant pulmonary lesions was reported. RESULTS In all, 134 publications were eligible for inclusion. In 168 patients CPM was found associated with lung tumor. The diagnosis was made in 76 children at a mean age of 3.68 ± 3.4, whereas in the adult population (n = 92) it was made at a mean age of 44.62 ± 16.09. Cough was the most frequent presenting symptom both in children and in adults. Most of the patients underwent lobectomy. The tumor most often associated with CPM was pleuropulmonary bastoma in children (n = 31) and adenocarcinoma (n = 20) or bronchioloalveolar carcinoma (n = 20) in adults. The CPM most frequenty associated with tumors in children was congenital cystic adenomatoid malformation (n = 37), especially type 1 (n = 21), whereas in adults it was bronchogenic cyst (n = 25), followed by congenital cystic adenomatoid malformation (n = 21). CONCLUSIONS CPMs should be followed up and never underestimated because they may conceal a tumor. Apparently, there is no age limit for malignant progression of CPMs and no limit of the interval between first detection of the CPM and appearance of the associated tumor.

Mediastinal teratoma with hydrops fetalis in a newborn and development of chronic respiratory insufficiency. Radiol Oncol 2014; 48:397-402.

Abstract
Background Mediastinal fetal teratoma can be detected as a mass in the chest during a routine prenatal ultra-sound screening. Because of the pressure on mediastinal structures it can be the cause of non-immune hydrops fetalis and polyhydramnion. The development of hydrops fetalis leads to fetal death or premature delivery in most reported cases. Early surgical removal is important, but, the result of treatment depends on the stage of development of mediastinal organs and complications in the postoperative period. Case report. A 31-year-old gravida carrying twins, with spontaneous membrane rupture at 32 weeks gestation underwent urgent caesarean section after antenatal ultrasound revealed severe polyhydramnion and hydrops fetalis in geminus A. The child was intubated immediately after birth due to severe respiratory distress. Ultrasound and X-ray revealed a tumour mass in the right hemithorax. Tumour resection was performed at the age of 7 days. Histology examination revealed an encapsulated immature teratoma. The postoperative course was complicated with respiratory insufficiency which turned into chronic at the age of eight months. Conclusion This is the fifth reported child with fetal mediastinal teratoma and severe hydrops fetalis that survived the neonatal period. Additional diagnostic search revealed abnormal course of both pulmonary arteries, which was probably one of the main causes of respiratory insufficiency.

Abstract
BACKGROUND AND OBJECTIVE Congenital pulmonary malformations (CPM) are mostly recognized on prenatal ultrasound scans. In a minority of cases, they may impair breathing at birth. The factors predictive of neonatal respiratory distress are not well defined, but an understanding of these factors is essential for decisions concerning the need for the delivery to take place in a tertiary care center. The aim of this study was to identify potential predictors of respiratory distress in neonates with CPM. METHODS We selected cases of prenatal diagnosis of hyperechoic and/or cystic lung lesions from RespiRare, the French prospective multicenter registry for liveborn children with rare respiratory diseases (2008-2013). Prenatal parameters were correlated with neonatal respiratory outcome. RESULTS Data were analyzed for 89 children, 22 (25%) of whom had abnormal breathing at birth. Severe respiratory distress, requiring oxygen supplementation or ventilatory support, was observed in 12 neonates (13%). Respiratory distress at birth was significantly associated with the following prenatal parameters: mediastinal shift (P = .0003), polyhydramnios (P = .05), ascites (P = .0005), maximum prenatal malformation area (P = .001), and maximum congenital pulmonary malformation volume ratio (CVR) (P = .001). Severe respiratory distress, requiring oxygen at birth, was best predicted by polyhydramnios, ascites, or a CVR >0.84. CONCLUSIONS CVR >0.84, polyhydramnios, and ascites increased the risk of respiratory complications at birth in fetuses with CPM, and especially of severe respiratory distress, requiring oxygen supplementation or more intensive intervention. In such situations, the delivery should take place in a tertiary care center.

Abstract
PURPOSE Congenital cystic adenomatoid malformations (CCAMs) are increasingly diagnosed in recent years due to the routine usage of antenatal ultrasound. The aim of this study was to present the natural course and outcome of antenatally diagnosed cystic lung diseases, which were prospectively studied. METHODS Between the period June 2004 and June 2010, 25 fetuses with suspected CCAMs were seen in a single tertiary maternal fetal unit. One child was excluded as the fetal MRI suggested congenital diaphragmatic hernia. Data were prospectively entered into a database including antenatal and postnatal findings which were then analyzed. RESULTS Mean gestational age at the time of diagnosis was 20.8 weeks (range 17-29). Fetal interventions included amnioreduction (n = 2) and fetal thoracocentesis (n = 3) in one child. The mean gestational age at delivery was 38.5 weeks (range 31.6-40.6). None of the mothers underwent termination of pregnancy or spontaneous abortion. All patients underwent postnatal radiological assessment. Of the 24 cases, 5 children were symptomatic in the immediate neonatal period and 19 were asymptomatic. Anatomical surgical resection was undertaken in all symptomatic cases. There was one death in this group due to severe pre-existing pulmonary hypoplasia. Among the 19 asymptomatic cases, 5 children were managed conservatively as the lesions were not significant and the remaining 14 (73%) underwent surgical resection. The mean age at surgery was 11.1 months (range 3.3-34 months). Postnatal pathology confirmed CCAM in all operated cases, except one who had pulmonary sequestration. CONCLUSION Antenatally diagnosed CCAMs have an excellent prognosis except in children with a large lesion and associated with lung hypoplasia. Postnatal investigations are required in all cases to confirm the diagnosis. Symptomatic CCAMs require immediate surgery in the neonatal period with a good outcome. Asymptomatic CCAMs can be safely operated between 9 and 12 months of age.

Abstract
OBJECTIVE Pneumatoceles are gas-filled cysts within the lung parenchyma resulting mostly from ventilator-induced lung injury and air-leak in premature infants with respiratory distress syndrome. The use of surfactant in the treatment of respiratory distress syndrome has resulted in a decrease in the incidence of air-leak disease. Our aim was to study the incidence and clinical course of pneumatoceles in the surfactant era. STUDY DESIGN A retrospective study of infants born at < or =30 weeks gestational age was admitted to the University of Connecticut Health Center NICU from 1998 to 2007. Pneumatoceles and other intrathoracic air-leaks were identified and comparisons were made with infants without these conditions. RESULT Pneumatoceles were identified in 19 preterm infants, born at gestational age < or =30 weeks, needing positive pressure ventilation for respiratory distress syndrome between the years 1998 to 2007. Pneumatoceles appeared early (median, 7th day of life; range, 1st to 28th day of life) and usually resolved with decrease in mean airway pressure (median, 4 days; range, 3 to 125 days). The majority of pneumatoceles were located in the right parahilar region (18/19). Associated intrathoracic air-leaks were pulmonary interstitial emphysema (5/19), pneumothorax (10/19), and pneumomediastinum (1/19). None of the infants required any invasive procedures to alleviate the pneumatoceles. In infants who survived, most pneumatoceles resolved with a decrease in mean airway pressure or extubation (14/15). One infant had a persistent pneumatocele for 125 days without any cardiopulmonary compromise and five infants died as a result air-leaks along with other complications of prematurity. CONCLUSION Pneumatoceles are a manifestation of intrathoracic air-leaks of prematurity. They are markers for ventilator-induced lung injury and are associated with significant mortality similar to other intrathoracic air-leaks. However, conservative management with reduction in mean airway pressure is effective in the resolution of this condition and interventional decompression of the pneumatocele is generally not necessary.

Abstract
Cystic lung disease is divided into congenital and acquired lesions. Congenital cystic lung disease includes several malformations with distinct anatomical and histological features. There is significant overlap between these lesions to suggest a common pathologic mechanism for their occurrence. Congenital cystic lung lesions include cystic adenomatoid malformations, pulmonary sequestrations, congenital lobar emphysema, and peripheral bronchogenic cysts. These lesions are commonly diagnosed prenatally with high accuracy. Prenatal imaging has allowed us to better understand their natural history and devise strategies for prenatal and postnatal management. Some lesions warrant resection (even prenatally), whereas others can be managed expectantly.

Abstract
PURPOSE We describe our experience with fetuses diagnosed with life-threatening chest masses who were delivered by ex utero intrapartum treatment with placement on extracorporeal membrane oxygenation (EXIT-to-ECMO). METHODS The first fetus presented with a cystic mediastinal mass and enlarging echogenic lungs. Bronchoscopic evaluation during ex utero intrapartum treatment (EXIT) revealed complete airway obstruction secondary to a carinal bronchogenic cyst. The second fetus presented with a massive left congenital cystic adenomatoid malformation. The EXIT procedure was performed because of significant mediastinal shift, severe compression of the normal lung parenchyma, and signs of fetal distress. RESULTS In both cases, extracorporeal membrane oxygenation (ECMO) was initiated while on placental support. The fetuses were then delivered, and a definitive resection of their thoracic lesions was successfully performed. There were no major perioperative complications. Both children made expedient recoveries without significant cardiopulmonary sequelae. CONCLUSION To our knowledge, this is the first report describing the successful use of EXIT-to-ECMO as a bridge to definitive resection of large chest masses diagnosed in utero. EXIT-to-ECMO is a novel and effective management strategy for stabilizing patients with profound respiratory compromise secondary to congenital thoracic lesions.

Abstract
This retrospective study reviews a series of teratomas of the neck and mediastinum aiming at defining the features of these particular locations. We recorded prenatal diagnosis, perinatal management, clinical and radiologic features, pathology, surgical strategies and results in cervical and mediastinal teratomas treated over the last 10 years. During this period we treated 66 children with teratoma of which 11 (6 male and 5 female) had cervicomediastinal locations. Five babies had cervical teratomas extended into the anterior mediastinum in two cases. Prenatal diagnosis was made in three (two with polyhydramnios). Four babies were born by C-section and only one had a successful EXIT procedure. The diagnosis was confirmed by imaging and increased AFP. Surgical treatment involved total tumor removal and in one case subsequent removal of lymph node metastases. All children survived except one in whom airway could not be cleared at birth. Two children bear mild hypothyroidism. During the same period six patients aged 0-17 years were treated for mediastinal teratoma. Only one was prenatally diagnosed and only two had some dyspnea. Removal was performed either by median sternotomy, thoracotomy, or thoracoscopy. They all survive and are free of disease. Teratomas of the neck may cause fetal disease and unmanageable neonatal airway obstruction. Prenatal diagnosis and planned multidisciplinary management are mandatory at birth. In contrast, only some mediastinal tumors cause respiratory embarrassment. Although benign, these tumors are sometimes immature and may metastasize to regional lymph nodes. Total surgical removal is curative. Thyroid insufficiency may be present at birth in cervical teratomas and may be aggravated by surgery.

Abstract
OBJECTIVE To examine the breadth of application and resulting outcomes in a university-based extracorporeal membrane oxygenation (ECMO) program directed by pediatric surgeons. SUMMARY BACKGROUND DATA Several randomized control trials have supported the use of ECMO in neonates with respiratory failure. No comparable data exist for older children and young adults who may be afflicted with a variety of uncommon conditions. The indications for ECMO in these patients remain controversial. METHODS Patient data were recorded prospectively and reported to the Extracorporeal Life Support Organization. These data were analyzed by indications and outcomes on all patients treated since the inception of the program. RESULTS Two hundred sixteen patients were treated with 225 courses of ECMO. Neonates (188 [87%]) outnumbered 28 older patients (aged 6 weeks to 22 years). Overall, 174 patients survived (81%). Sixty-four of 65 (98.5%) neonates with meconium aspiration syndrome survived. ECMO support after heart (3), lung (2), heart-lung (1), and liver (1) transplant yielded a 57% survival to discharge. ECMO also resulted in survival of patients with uncommon conditions, including severe asthma (1), hydrocarbon aspiration (1/2), congestive heart failure due to a cerebral arteriovenous malformation (1), tracheal occlusion incurred during endoscopic stent manipulation (2), meningitis (1), and viral pneumonia (3/5). CONCLUSIONS ECMO can potentially eliminate mortality for meconium aspiration syndrome. Survival for other causes of respiratory failure in neonates and older children, while not as dramatic, still surpasses that anticipated with conventional therapy. Moreover, survival of transplant patients has been comparable to that achieved in other children.

Abstract
For safer and simpler neonatal ECMO management, the authors have been developing an innovative, automatically-controlled ECMO machine using self-regulating blood pumps. The newest model is an air-driven, tube-type blood pump. A pair of blood pumps are placed in parallel and actuated alternately with compressed air. The pump flow is automatically regulated in accordance with hemodynamic changes of the body. The need for a venous reservoir is eliminated because the circuit does not generate excessive negative pressure when there are shortages of draining blood. Therefore, the priming volume of the circuit is only 85 ml. This ECMO apparatus has three driving modes, one of which is a "delay" mode. This enables the pump flow to easily be varied from 10 to 500 ml/min under automatic control, and it can be used when the pump flow is decreased for weaning. This newest ECMO apparatus was clinically used in 3 neonates with severe lung hypoplasia and persistent fetal circulation. The ECMO duration was 139 h to 168 h, and the maximum ECMO flow 71.3 to 109.0 ml/min/kg. Thanks to the self-regulation, intensive observation of the circuit was not necessary during ECMO. Damage to blood cells was less significant, and the use of blood products was only minimal (15.7 ml/kg/day) because a large volume of blood to stabilize the pump performance was not necessary. In conclusion, the automatically-controlled ECMO apparatus worked well without complications by changing the ECMO flow automatically in accordance with hemodynamic changes. This automatic ECMO system required fewer personnel expenditures and was also favorable in terms of hematological findings.

Abstract
A patient with congenital cystic adenomatoid malformation of the lung (CCAM) is presented who showed severe respiratory deterioration in the neonatal period caused by hyperinflation of the cystic component and compression of the contralateral lung. Transthoracic drainage of the cyst was performed to avoid preoperative artificial ventilation. On aspiration, air and liquid was removed from the cyst. After stabilization, surgical intervention was performed within 24 hours. Postoperative recovery was uneventful, and the child was discharged at day 13.

Abstract
The etiology of CCAM of the lung remains unclear. Presentations vary, with clinical outcomes that may be unpredictable. The neonatal nurse should be equipped to detect the sometimes subtle radiologic images these lesions produce and should be able to distinguish CCAM from similar chest masses. Expediting this diagnosis postnatally benefits the neonate by preventing further expansion of the cysts, which can cause a cascade of complications, including air leaks, cardiorespiratory compromise, and PPHN.
