J Perinatol 2024; 44:1454-1462. [PMID: 38831120 DOI: 10.1038/s41372-024-02019-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 05/20/2024] [Accepted: 05/23/2024] [Indexed: 06/05/2024]
Abstract
OBJECTIVE Review a cohort of preterm infants ≤29 weeks of gestation at birth and compare morbidities and neurodevelopmental outcomes based on PDA status and type of PDA closure. STUDY DESIGN Single center observational retrospective-prospective case control study of premature infants who had no hsPDA, underwent surgical ligation or percutaneous transcatheter closure of the PDA. Neurodevelopmental testing was done using the Bayley Scales of Infant Development 3rd ed. RESULTS The percutaneous transcatheter closure group had an older post menstrual age and greater weight at the time of procedure, and started enteral feeds and achieved room air status at an earlier post procedure day. Infants in the surgical ligation group were more likely to experience vocal cord paralysis. There was no difference in neurodevelopmental outcomes between groups. CONCLUSION Waiting for infants to achieve the appropriate size for percutaneous transcatheter closure of the PDA may lead to reduced short-term complications without increasing the risk of neurodevelopmental impairment.

Effectiveness of intraoperative nerve monitoring in reducing rates of recurrent laryngeal nerve injury in aerodigestive and cardiovascular pediatric surgery. Surgery 2024:S0039-6060(24)00587-7. [PMID: 39294009 DOI: 10.1016/j.surg.2024.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 06/20/2024] [Accepted: 08/07/2024] [Indexed: 09/20/2024]
Abstract
OBJECTIVE To investigate the effectiveness of intraoperative nerve monitoring at decreasing vocal fold movement impairment in children undergoing at-risk procedures. BACKGROUND Children undergoing aerodigestive or cardiovascular procedures are at risk for recurrent laryngeal nerve injury, leading to vocal fold movement impairment. Although intraoperative nerve monitoring has been shown to decrease recurrent laryngeal nerve injury in adults, there is paucity of data in children. METHODS This was a retrospective, single-center cohort study of children who underwent airway, esophageal, or great vessel surgery between 2018 and 2023. Vocal fold movement impairment was evaluated with pre- and postoperative awake flexible fiberoptic laryngoscopy. Vocal fold movement impairment rates and associated characteristics were compared between those with and without intraoperative nerve monitoring. RESULTS Among 387 children undergoing 426 at-risk procedures, intraoperative nerve monitoring was used in 72.1% (n = 307) of procedures. Intraoperative nerve monitoring significantly reduced postoperative vocal fold movement impairment compared with those without (11.4% vs 20.2%, P = .019, 43.6% relative risk reduction, number needed to treat: 12). In children with a pre-existing vocal fold movement impairment (n = 79, 18.5%), intraoperative nerve monitoring provided enhanced protection (vocal fold movement impairment 7.8% with intraoperative nerve monitoring compared with 25% without, P = .046, 68.6% relative risk reduction, number needed to treat: 3). Bilateral vocal fold movement impairment was 14 times more likely without intraoperative nerve monitoring (1.8% overall, 0.3% with intraoperative nerve monitoring, 5.6% without; 95% confidence interval 1.6-123.2; P = .006). Increasing intraoperative nerve monitoring use correlated with decreasing vocal fold movement impairment rates year over year (P = .046). Multivariable logistic regression demonstrated intraoperative nerve monitoring to remain significantly associated with reduced risk of vocal fold movement impairment (odds ratio, 0.48; 95% confidence interval, 0.26-0.85; P = .013). CONCLUSION Intraoperative nerve monitoring in children seems effective at decreasing recurrent laryngeal nerve injury and consequently vocal fold movement impairment. Intraoperative nerve monitoring should be considered in children undergoing cervicothoracic or cardiothoracic procedures, especially in those with preoperative vocal fold movement impairment.

Abstract
Unilateral vocal cord paralysis (UVCP) is a growing area of research in pediatrics as it spans across many specialties including otolaryngology, cardiology, general surgery, respirology, and speech language pathology. Iatrogenic injury is the most common cause of UVCP, however there is a wide range of data reporting the prevalence, symptom burden, and best treatment practice for this condition. The literature included systematic reviews and meta-analyses, retrospective studies and limited prospective studies. Overall, the literature lacked consistency in the diagnosis, treatment, and long-term outcomes of patients with UVCP. Many articles conflated bilateral vocal cord paralysis (BVCP) with UVCP and had limited data on the natural history of the condition. There was no consensus on objective and subjective measurements to evaluate the condition or best indications for requiring surgical intervention. Thyroplasty, injection medialization (IM) and recurrent laryngeal nerve reinnervation (RLNR) were the reported surgical interventions used to treat UVCP, however there was limited data on short and long-term surgical outcomes in children. More research is needed to determine the true prevalence, natural history, indications for surgical intervention and long-term outcomes for pediatric patients with this condition.

Abstract
Perioperative applications of near-infrared spectroscopy (NIRS) to monitor regional tissue oxygenation and perfusion in cardiac and noncardiac surgery are of increasing interest in neonatal care. Complex neonatal surgery can impair adequate oxygen delivery and tissue oxygen consumption and increase the risk of neurodevelopmental delay. Coupled with conventional techniques, NIRS monitoring may enable targeted hemodynamic management of the circulation in both cardiac and noncardiac surgical procedures. In this narrative review, we discuss the application of perioperative NIRS in specific neonatal interventions, including surgical intervention for congenital heart defects, definitive closure of the patent ductus arteriosus, neurological and gastrointestinal disorders, and use of extracorporeal membrane oxygenation. We identified areas for future research within disease-specific indications and offer a roadmap to aid in developing evidence-based targeted diagnostic and management strategies in neonates. IMPACT: There is growing recognition that perioperative NIRS monitoring, used in conjunction with conventional monitoring, may provide critical hemodynamic information that either complements clinical impressions or delivers novel physiologic insight into the neonatal circulatory and perfusion pathways.

Abstract
INTRODUCTION Children undergoing cervical and/or thoracic operations are at risk for recurrent laryngeal nerve injury, resulting in vocal fold movement impairment (VFMI). Screening for VFMI is often reserved for symptomatic patients. OBJECTIVE Identify the prevalence of VFMI in screened preoperative patients prior to an at-risk operation to evaluate the value of screening all patients at-risk for VFMI, regardless of symptoms. METHODS A single center, retrospective review of all patients undergoing a preoperative flexible nasolaryngoscopy between 2017 and 2021, examining the presence of VFMI and associated symptoms. RESULTS We evaluated 297 patients with a median (IQR) age of 18 (7.8, 56.3) months and a weight of 11.3 (7.8, 17.7) kilograms. Most had a history of esophageal atresia (EA, 60%), and a prior at-risk cervical or thoracic operation (73%). Overall, 72 (24%) patients presented with VFMI (51% left, 26% right, and 22% bilateral). Of patients with VFMI, 47% did not exhibit the classic symptoms (stridor, dysphonia, and aspiration) of VFMI. Dysphonia was the most prevalent classic VFMI symptom, yet only present in 18 (25%) patients. Patients presenting with a history of at-risk surgery (OR 2.3, 95%CI 1.1, 4.8, p = 0.03), presence of a tracheostomy (OR 3.1, 95%CI 1.0, 10.0, p = 0.04), or presence of a surgical feeding tube (OR 3.1, 95%CI 1.6, 6.2, p = 0.001) were more likely to present with VFMI. CONCLUSION Routine screening for VFMI should be considered in all at-risk patients, regardless of symptoms or prior operations, particularly in those with a history of an at-risk surgery, presence of tracheostomy, or a surgical feeding tube. LEVEL OF EVIDENCE 3 Laryngoscope, 133:3564-3570, 2023.

Abstract
Persistent patent ductus arteriosus is a very common condition in preterm infants. Although there is no management agreed by consensus, despite numerous randomized controlled trials, hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. Medical treatment is usually offered as first-line therapy, although it carries a limited success rate and potential severe adverse events. In recent years, transcatheter patent ductus arteriosus closure has fast developed and become widely accepted as a safe and efficient alternative to surgical ductal ligation in extremely low birth weight infants >700 g, using most often the dedicated Amplatzer Piccolo Occluder device. This article aims to provide an appraisal of the patients' selection process, and a step-by-step description of the procedure as well as a comprehensive review of its outcomes.

Abstract
OBJECTIVE To assess dysphagia outcomes following surgical management of unilateral vocal fold immobility in children. DATA SOURCES Ovid Medline, Embase, Web of Science, and CENTRAL databases. REVIEW METHODS A systematic review of the medical literature was performed following the PRISMA guidelines. An a priori protocol was defined to identify all articles that presented quantifiable outcome data in children aged <18 years who underwent surgical treatment to improve glottal competence for dysphagia. Two authors independently determined references meeting the inclusion criteria, extracted data, and assigned levels of evidence. Data were pooled via a random effects model where possible. The quality of studies was graded with the MINORS criteria. RESULTS An overall 398 publications were screened, with 9 meeting inclusion criteria. A total of 115 patients were included. Of these, 75% had preoperative swallowing symptoms. Surgical intervention for dysphagia included 61 injection laryngoplasties, 11 medialization laryngoplasties, and 10 reinnervations (ansa cervicalis to recurrent laryngeal nerve). The articles consistently reported success in improving dysphagia symptoms, and limited meta-analysis demonstrated a mean improvement after surgical intervention in 79% (95% CI, 67%-91%) of children. The reported rate of minor and major complications was 15% (95% CI, 1%-29%). The MINORS scores ranged from 5 to 12. CONCLUSION Surgical management of unilateral vocal fold immobility in properly selected children can be an effective treatment for dysphagia when symptoms are present. Selection of surgical modalities relies on patient- and surgeon-related factors, and the rate of success is high across different interventions in treating these complex children.

Abstract
BACKGROUND Hoarseness due to laryngeal nerve injury is a known complication after cardiothoracic surgery involving the aortic arch. However, this complication is only rarely reported after catheter interventions. RESULTS In this article we present the unusual case of a left-sided vocal cord paralysis in four patients after primary stenting of a re-coarctation, re-dilatation of a stented coarctation, a primary stenting of the left pulmonary artery (LPA), and prestenting for percutaneous pulmonary valve implantation with dilation of the LPA. After implanting bare metal stents, it is common practice, whilst contemplating the diameters of the adjacent structures, to optimize the stent diameter in a two-step procedure and dilate the stent until a maximum diameter is achieved and there is no residual gradient after applying this technique. Four of our patients experienced hoarseness after the intervention and a vocal cord paralysis was diagnosed. Angiography revealed no signs of extravasation or dissection. Clinical symptoms improved over the course of the following 6 months; patients with interventions at the aortic arch showed a complete remission, patients with procedures involving the LPA showed only mild regression of the symptoms. CONCLUSION To our knowledge, this complication (Ortner's syndrome, cardiovocal syndrome) after such interventions has rarely been reported before. Although a rare complication, the recognition of these symptoms may support colleagues in managing affected patients. In addition, awareness for hoarseness after interventional therapies and systematic screening for this complication might help to identify patients at risk in the future.

Abstract
OBJECTIVE To test whether prospective classification of infants with bronchopulmonary dysplasia identifies lower-risk infants for discharge with home oxygen who have fewer rehospitalizations by 1 year after neonatal intensive care unit discharge. STUDY DESIGN This is a prospective single-center cohort that included infants from 2016 to 2019 with bronchopulmonary dysplasia, defined as receiving respiratory support at 36 weeks of postmenstrual age. "Lower-risk" infants were receiving ≤2 L/min nasal cannula flow, did not have pulmonary hypertension or airway comorbidities, and had blood gas partial pressure of carbon dioxide <70 mm Hg. We compared 3 groups by discharge status: lower-risk room air, lower-risk home oxygen, and higher-risk home oxygen. The primary outcome was rehospitalization at 1 year postdischarge, and the secondary outcomes were determined by the chart review and parent questionnaire. RESULTS Among 145 infants, 32 (22%) were lower-risk discharged in room air, 49 (32%) were lower-risk using home oxygen, and 64 (44%) were higher-risk. Lower-risk infants using home oxygen had rehospitalization rates similar to those of lower-risk infants on room air (18% vs 16%, P = .75) and lower rates than higher-risk infants (39%, P = .018). Lower-risk infants using home oxygen had more specialty visits (median 10, IQR 7-14 vs median 6, IQR 3-11, P = .028) than those on room air. Classification tree analysis identified risk status as significantly associated with rehospitalization, along with distance from home to hospital, inborn, parent-reported race, and siblings in the home. CONCLUSIONS Prospectively identified lower-risk infants discharged with home oxygen had fewer rehospitalizations than higher-risk infants and used more specialty care than lower-risk infants discharged in room air.

Abstract
INTRODUCTION Pediatric laryngeal mobility disorders constitute a challenge in terms of diagnosis and treatment, especially in small children and those complex patients with prior history of prolonged intubation or surgery. Laryngeal electromyography (L-EMG) may help to distinguish vocal fold paralysis from fixation. MATERIAL AND METHODS Ten children with laryngeal mobility disorders (including bilateral vocal fold immobility (BVFI) or unilateral vocal fold immobility (UVFI) with contralateral hypomobility) underwent suspension laryngoscopy and L-EMG between July 2019 and March 2021. The EMG data were acquired simultaneously in both thyroarytenoid muscles. Anesthesia was lightened until volitional activity appeared like cough, cry or spontaneous Valsalva maneuver. RESULTS We found secondary airway lesions in 2 patients and 3 vocal fold fixation. L-EMG recordings were pathologic in 4 patients (3 moderate and 1 severe nerve lesion). No recurrent laryngeal nerve injury was found in congenital BVFI cases. The data from both suspension laryngoscopy and L-EMG recordings influenced clinical decision-making. CONCLUSIONS L-EMG adds value to suspension laryngoscopy in the management of pediatric patients with laryngeal mobility disorders. Selected cases such as patients with iatrogenic BVFI, UVFI with associated contralateral hypomobility or patients with combined pathologies may obtain the greatest benefit.

Abstract
The burden of patent ductus arteriosus (PDA) continues to be significant. In view of marked differences in preterm infants versus more mature, term counterparts (viewed on a continuum with adolescent and adult patients), mechanisms regulating ductal patency, genetic contributions, clinical consequences, and diagnostic and treatment thresholds are discussed separately, when appropriate. Among both preterm infants and older children and adults, a range of hemodynamic profiles highlighting the markedly variable consequences of the PDA are provided. In most contemporary settings, transcatheter closure is preferable over surgical ligation, but data on longer-term outcomes, particularly among preterm infants, are lacking. The present review provides recommendations to identify gaps in PDA diagnosis, management, and treatment on which subsequent research can be developed. Ultimately, the combination of refined diagnostic thresholds and expanded treatment options provides the best opportunities to address the burden of PDA. Although fundamental gaps remain unanswered, the present review provides pediatric and adult cardiac care providers with a contemporary framework in PDA care to support the practice of evidence-based medicine.

Abstract
INTRODUCTION In patients undergoing patent ductus arteriosus (PDA) ligation there is a significant risk of left vocal fold paralysis (LVFP) particularly in premature neonates who are small for gestational age. The objective of this study is to determine the incidence of LVFP in infants following PDA ligation and report on long-term outcomes in patients with LVFP. METHODS We performed a prospective study of patients undergoing PDA ligation in the newborn intensive care unit (NICU) between April 2004 and May 2014. Following PDA ligation, flexible laryngoscopy was performed to assess vocal fold mobility. Patients were then followed longitudinally to determine long-term outcomes. RESULTS A total of 163 infants underwent PDA ligation. Thirty-six patients (22%) developed LVFP following the procedure. Twenty-five percent of neonates <1500 g experienced LVFP versus 5% of patients >1500 g (p = 0.033). Patients with LVFP were more likely to require a feeding tube (64% vs. 19.6%; p < 0.05) and spent more time in the NICU (135 days vs. 106 days; p < 0.05). Twenty-four patients received long-term follow-up. Six (25%) had complete resolution of LVFP, 10 (42%) were compensated, and 8 (33%) demonstrated persistent LVFP with no improvement. CONCLUSIONS The incidence of LVFP after PDA ligation is high especially in extremely low birth weight children. The majority of patients recovered well with time, but further surgical intervention was required in uncompensated cases. Long-term follow-up of these patients is needed to ensure improvement.

Abstract
Vocal cord paralysis is a common cause of respiratory and feeding problems in the pediatric population. While the causes of vocal cord paralysis are multiple, iatrogenic injury of the recurrent laryngeal nerve after cardiovascular surgery is the most frequent cause. Vocal cord paralysis increases the risk of swallowing dysfunction, tracheal aspiration and pneumonia. It also increases the need for nasoenteric feeds and gastrostomy tube placement. Flexible nasopharyngolaryngoscopy is considered the gold standard for diagnosing vocal cord paralysis, but it has significant drawbacks: it is uncomfortable, it can trigger a cardiovascular event in children with unstable cardiovascular status, it can be challenging to perform, and it can be difficult to interpret. Laryngeal US has become a popular imaging modality to evaluate the function of the vocal cords. Laryngeal US is well-tolerated, easy to perform, simple to interpret and has a lower physiological impact compared to flexible nasopharyngolaryngoscopy. Laryngeal US is an accurate and low-cost diagnostic test for vocal cord paralysis. In this review, we describe the anatomy of the larynx and recurrent laryngeal nerve; the causes, symptoms and pathophysiology of vocal cord paralysis; laryngeal US technique; diagnostic criteria for vocal cord paralysis; and a reporting system.

Abstract
INTRODUCTION Laryngeal mobility disorder after a pediatric heart surgery is common (between 5 and 10% of cases), and has important consequences on swallowing, breathing and speaking. After reviewing the literature, the recovery rate is variable and the postoperative follow-up is often done on a short time frame. The primary objective of the study is to describe the recovery from laryngeal mobility disorder with a follow-up time of at least 5 years. The secondary objective is to describe of the quality of life of the child in terms of phonation and swallowing, and to identify potential risk factors for a lasting laryngeal mobility disorder. METHODS We collected data (morphological characteristics and details of the procedures and medical care) on children who had undergone a heart surgery with risks of complications, between 2010 and 2015, and with a laryngeal mobility disorder detected after the surgery through nasal flexible laryngoscopy. During a follow-up consultation, carried at least 5 years after the surgery, we performed a nasal flexible laryngoscopy to assess whether or not the patient had recovered a full mobility of the larynx. Two questionnaires were also given to the patients, the pVHI and the PEDI EAT-10, to assess respectively the quality of their speech and of their swallowing function. RESULTS The recovery rate for a laryngeal mobility disorder more than 5 years after surgery was found to be 65% (9 children out of the 14 included in the study). We identified a risk factor for the persistence of a laryngeal mobility disorder after surgery: the presence of an associated genetic syndrome, p = 0.025. Children with persistent laryngeal mobility disorder have an impaired quality of life score, using the pVHI scale, which correlates well with the flexible laryngoscopy findings, p = 0.033. CONCLUSION Children with a lasting laryngeal mobility disorder have disabling respiratory and vocal symptoms in their daily lives. Nasal flexible laryngoscopy should therefore be systematically performed postoperatively after a surgery carrying risks. For improved patient management, early detection of these disorders by pharyngolaryngeal nasal flexible laryngoscopy in the aftermath of high-risk cardiac surgery is strongly advised, with prolonged follow-up.

Abstract
IMPORTANCE No evidence-based treatment protocol currently exists for infants with vocal cord paresis (VCP). OBJECTIVE To assess the impact of feeding position on feeding success among infants with unilateral VCP and examine other variables that may be associated with feeding success. DESIGN Retrospective descriptive study. SETTING Midwestern pediatric hospital serving rural and urban populations. PARTICIPANTS Sixty-seven infants age <1 yr diagnosed with unilateral VCP by otolaryngologist while inpatient. OUTCOMES AND MEASURES Bottle or breastfeeding without the use of a thickening agent at discharge and without readmission for feeding difficulties ≤3 mo of discharge was considered feeding success. RESULTS Chart review was completed for 67 infants with unilateral VCP. Infants fed in side lying were more likely to feed without use of a thickened liquid than infants fed in upright (70% vs. 17%; p = .01). Infants who had patent ductus arteriosus (PDA) ligation and infants who were premature were more likely to need thickener and to be readmitted for feeding difficulties. CONCLUSIONS AND RELEVANCE Further study is required to investigate the use of side-lying position versus upright position for feeding infants with VCP. Using the side-lying position allowed more infants to feed without thickener agents, and patient characteristics, including history of PDA ligation and prematurity, correlated with the need for thickened liquids and readmission. Consensus on the safety and efficacy of thickening breast milk is limited, so this information may allow more infants to breastfeed or drink expressed breast milk safely by bottle. It also provides medical providers information that can possibly prevent readmissions. What This Article Adds: The results of this study can inform occupational therapy feeding practice through use of the side-lying position, as well as being aware of patient characteristics that are correlated with increased feeding difficulties.

Abstract
Background: Premature birth affects millions of neonates each year, placing them at risk for respiratory disease due to prematurity. Bronchopulmonary dysplasia is the most common chronic lung disease of infancy, but recent data suggest that even premature infants who do not meet the strict definition of bronchopulmonary dysplasia can develop adverse pulmonary outcomes later in life. This post-prematurity respiratory disease (PPRD) manifests as chronic respiratory symptoms, including cough, recurrent wheezing, exercise limitation, and reduced pulmonary function. This document provides an evidence-based clinical practice guideline on the outpatient management of infants, children, and adolescents with PPRD. Methods: A multidisciplinary panel of experts posed questions regarding the outpatient management of PPRD. We conducted a systematic review of the relevant literature. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of the clinical recommendations. Results: The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Recommendations were developed for or against three common medical therapies and four diagnostic evaluations in the context of the outpatient management of PPRD. Conclusions: The panel developed recommendations for the outpatient management of patients with PPRD on the basis of limited evidence and expert opinion. Important areas for future research were identified.

Abstract
BACKGROUND Vocal cord palsy is one of the recognised complications of complex cardiac surgery in the paediatric population. While there is an abundance of literature highlighting the presence of this complication, there is a scarcity of research focusing on the pathophysiology, presentation, diagnosis, and treatment options available for children affected by vocal cord palsy. MATERIALS AND METHODS Electronic searches were conducted using the search terms: "Vocal Cord Palsy," "VCP," "Vocal Cord Injury," "Paediatric Heart Surgery," "Congenital Heart Surgery," "Pediatric Heart Surgery," "Vocal Fold Movement Impairment," "VFMI," "Vocal Fold Palsy," "PDA Ligation." The inclusion criteria were any articles discussing the outcomes of vocal cord palsy following paediatric cardiac surgery. RESULTS The two main populations affected by vocal cord palsy are children undergoing aortic arch surgery or those undergoing PDA ligation. There is paucity of prospective follow-up studies; it is therefore difficult to reliably assess the current approaches and the long-term implications of management options. CONCLUSION Vocal cord palsy can be a devastating complication following cardiac surgery, which if left untreated, could potentially result in debilitation of quality of life and in severe circumstances could even lead to death. Currently, there is not enough high-quality evidence in the literature to aid recognition, diagnosis, and management leaving clinicians to extrapolate evidence from adult studies to make clinical judgements. Future research with a focus on the paediatric perspective is necessary in providing evidence for good standards of care.

Abstract
Patent ductus arteriosus (PDA) may be found in 0.1-0.2% of term infants, but the average incidence is at least five-fold higher in premature infants, correlating inversely with birth weight and gestational age. While not all patients with a PDA require treatment, the deleterious effects of persistent left-to-right shunting across the ductus can have important short- and long-term consequences. Medical and interventional approaches to PDA closure have evolved greatly in the past decade and add to the decision-making pathways. This article summarizes the pathophysiology of PDA and characterizes the medical, surgical and endovascular treatment approaches.

Abstract
While there is a very large focus on the abnormalities of parenchymal lung development and extensive efforts to minimize alveolar damage with "gentle ventilation" and noninvasive respiratory support for neonates with bronchopulmonary dysplasia (BPD), there is relatively little consideration for the implications of central airway disease in this patient population. There are significant changes in the structure and conformation of the central airway during the last half of gestation, and premature birth disrupts this natural developmental process. The arrest of maturation results in a smaller airway that is more compliant, easier to deform, and more susceptible to damage. Consequently, neonates with BPD are prone to developing central airway pathology, particularly for patients who require intubation and positive pressure ventilation. Central airway disease can be divided into dynamic and fixed airway obstruction and results in increased respiratory morbidity in neonates with chronic lung disease of prematurity.

Abstract
BACKGROUND To analyze the change and clinical significance of cortisol, B-type brain natriuretic peptide (BNP), and prostacyclin-2 (PGE-2) levels in premature infants with patent ductus arteriosus (PDA). METHODS A total of 67 cases of premature infants admitted to our hospital from January 2018 to April 2020 were included, all of whom developed PDA (PDA group). According to the presence or absence of symptoms, they were divided into the symptomatic group (28 cases) and the asymptomatic group (39 cases). In addition, 62 premature infants without PDA who were born in our hospital during the same period were selected as the control group. The expression levels of cortisol, BNP, and PGE-2 in infants in different groups and between infants with symptoms and without symptoms were analyzed, along with the risk factors leading to PDA in preterm infants. The value of cortisol, BNP, and PGE-2 in the diagnosis of PDA in premature infants was also analyzed. RESULTS Compared with the control group, cortisol in the PDA group was significantly decreased (P<0.05), while the levels of BNP and PGE-2 were significantly increased (P<0.05). The cortisol level in the asymptomatic group was significantly higher than that in the symptomatic group, while the levels of BNP and PGE-2 were opposite, and the differences were statistically significant (P<0.05). Logistic regression analysis showed that birth weight <1,200 g, decreased cortisol, increased BNP, and increased PGE-2 were independent risk factors leading to PDA in preterm infants, and the differences were statistically significant (P<0.05). Receiver operating characteristic (ROC) curve showed that the sensitivity and specificity of cortisol+BNP+PGE-2 in the diagnosis of PDA in premature infants were 75.60% and 73.10%, respectively. The area under the curve (AUC) value was 0.759 (95% CI: 0.611-0.859), which was significantly higher than the AUC values of the 3 tests alone (P<0.05). CONCLUSIONS The expression of cortisol decreased in premature infants with PDA, while the levels of BNP and PGE-2 significantly increased. Dynamic detection of the changes in these levels can provide an important reference for the early diagnosis of PDA and for the assessment of disease progression.

Abstract
RATIONALE The management of neonates with patent ductus arteriosus (PDA) has changed over time. METHODS We conducted a single-city, retrospective review of neonates who underwent PDA ligation over a 10-year time period and compared infants from the first 5 years to the second 5 years to evaluate how clinical characteristics changed over this time. RESULTS Infants from the second 5-year epoch were older at time of ligation (38 vs. 30 days), had a higher ligation weight (1432 vs. 1121 g) and a lower incidence of postligation cardiac syndrome (1.9% vs. 11.5%). No differences in mortality, length of hospital-stay or major morbidities were seen. Compared to neonates who underwent PDA ligation at ≤28 days of life, those with a ligation age >28 days had a higher ligation weight (1421 vs. 1039 g), a higher proportion of COX inhibitor use (92.5% vs. 83.8%), and a higher incidence of moderate-severe bronchopulmonary dysplasia (BPD) (60.4% vs. 44.4%). Only 10.7% (25/233) patients were evaluated by laryngoscopy, in which the incidence of vocal cord paralysis (VCP) was 36.0%; 2 patients were clinically diagnosed with VCP for a total 4.7% incidence of VCP (11/233). CONCLUSIONS Over the 10 years examined, neonates underwent PDA ligation at an older age in the second 5-year time period; this change was not associated with a change in the incidence of major morbidities. Ligation age >28 days was associated with an increase incidence of moderate-severe BPD. The overall incidence of documented VCP post-PDA ligation was relatively low but was seen in over 1/3 who were evaluated by laryngoscopy.

The molecular mechanisms of oxygen-sensing in human ductus arteriosus smooth muscle cells: A comprehensive transcriptome profile reveals a central role for mitochondria. Genomics 2021; 113:3128-3140. [PMID: 34245829 PMCID: PMC10659099 DOI: 10.1016/j.ygeno.2021.07.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 06/23/2021] [Accepted: 07/04/2021] [Indexed: 01/22/2023]
Abstract
The ductus arteriosus (DA) connects the fetal pulmonary artery and aorta, diverting placentally oxygenated blood from the developing lungs to the systemic circulation. The DA constricts in response to increases in oxygen (O2) with the first breaths, resulting in functional DA closure, with anatomic closure occurring within the first days of life. Failure of DA closure results in persistent patent ductus arteriosus (PDA), a common complication of extreme preterm birth. The DA's response to O2, though modulated by the endothelium, is intrinsic to the DA smooth muscle cells (DASMC). DA constriction is mediated by mitochondrial-derived reactive oxygen species, which increase in proportion to arterial partial pressure of oxygen (PaO2). The resulting redox changes inhibit voltage-gated potassium channels (Kv) leading to cell depolarization, calcium influx and DASMC constriction. To date, there has not been an unbiased assessment of the human DA O2-sensors using transcriptomics, nor are there known molecular mechanisms which characterize DA closure. DASMCs were isolated from DAs obtained from 10 term infants at the time of congenital heart surgery. Cells were purified by flow cytometry, negatively sorting using CD90 and CD31 to eliminate fibroblasts or endothelial cells, respectively. The purity of the DASMC population was confirmed by positive staining for α-smooth muscle actin, smoothelin B and caldesmon. Cells were grown for 96 h in hypoxia (2.5% O2) or normoxia (19% O2) and confocal imaging with Cal-520 was used to determine oxygen responsiveness. An oxygen-induced increase in intracellular calcium of 18.1% ± 4.4% and SMC constriction (-27% ± 1.5% shortening) occurred in all cell lines within five minutes. RNA sequencing of the cells grown in hypoxia and normoxia revealed significant regulation of 1344 genes (corrected p < 0.05). We examined these genes using Gene Ontology (GO). This unbiased assessment of altered gene expression indicated significant enrichment of the following GOterms: mitochondria, cellular respiration and transcription. The top regulated biologic process was generation of precursor metabolites and energy. The top regulated cellular component was mitochondrial matrix. The top regulated molecular function was transcription coactivator activity. Multiple members of the NADH-ubiquinone oxidoreductase (NDUF) family are upregulated in human DASMC (hDASMC) following normoxia. Several of our differentially regulated transcripts are encoded by genes that have been associated with genetic syndromes that have an increased incidence of PDA (Crebb binding protein and Histone Acetyltransferase P300). This first examination of the effects of O2 on human DA transcriptomics supports a putative role for mitochondria as oxygen sensors.

Abstract
OBJECTIVES Patients with vocal cord paralysis can experience feeding, respiratory, and vocal problems leading to disability and decreased quality of life. Current evidence suggests waiting a period of 12 months for spontaneous recovery before permanent interventions. This study aims to determine the time to recover spontaneously and vocal cord movement in a pediatric population and create a model for evidence-based patient counseling. STUDY DESIGN Retrospective longitudinal cohort study. METHODS The report is a single institution longitudinal study on vocal cord paralysis recovery. Patients were categorized based on spontaneous recovery with vocal cord movement or no recovery. Recovery rates were determined using the Kaplan-Meier method. RESULTS Of 158 cases of vocal cord paralysis over a 4-year period, 36 had spontaneous recovery with symptom improvement and motion return. The average recovery was 8.8 months for those who recovered, and 78% recovered within 9 months. Two groups emerged from the data: an early recovery group with spontaneous recovery before 12 months and a late recovery group after 12 months. Children with dysphonia and paralysis due to cardiac surgery were less likely to recover, and children with aspiration were more likely to recover. Children with gastrointestinal comorbidities were less likely to recover; however, those who did recover were more likely to have recovered after 12 months. Based on our model, there is about a 3% chance of recovery between 9 and 12 months. CONCLUSIONS Patients should be counseled about earlier interventions. Waiting the conventional 12 months for only a 3% chance of spontaneous recovery without intervention or laryngeal EMG may not be the preferred option for some patients and their families.

Abstract
Vocal fold immobility in children can affect breathing, swallowing, and speech function. Although sometimes idiopathic, it is often caused by injury to the recurrent laryngeal nerve during cardiac surgery. A detailed history and physical examination can identify risk factors, which affect the rate of resolution and overall prognosis. Fiberoptic laryngoscopy can be used to confirm the diagnosis and evaluate laryngeal anatomy. Many treatment options exist to improve function and quality of life, including vocal fold injection and laryngeal innervation. [Pediatr Ann. 2021;50(7):e286-e291.].

Abstract
OBJECTIVE The purpose of the study was to quantify cost savings after promoting oral pharmacotherapy for the treatment of hemodynamically significant patent ductus arteriosus (hsPDA). METHODS This was a retrospective before-and-after time series quality improvement study. Oral ibuprofen and acetaminophen use criteria were developed and recommended, rather than the more costly intravenous equivalents. There were 24-month medication use reports generated for both the pre-criteria (Era-1) and the post-criteria (Era-2) implementation phases to identify neonates prescribed hsPDA medications in order to assess cost differences. RESULTS Era-1 had 190 treatment courses in 110 neonates for a total medication cost of $171,260.70. Era-2 had 210 courses in 109 patients for a total medication cost of $47,461.49, yielding savings of $123,799.21 ($61,899.61 annually) after criteria implementation. The reduction in intravenous ibuprofen use in Era-2 accounted for all the savings. CONCLUSION Preferentially prescribing lower-cost oral medications to treat hsPDA led to significant cost savings.

Left Vocal Cord Paralysis, Lung Function and Exercise Capacity in Young Adults Born Extremely Preterm With a History of Neonatal Patent Ductus Arteriosus Surgery-A National Cohort Study. Front Pediatr 2021; 9:780045. [PMID: 35047462 PMCID: PMC8761768 DOI: 10.3389/fped.2021.780045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Accepted: 11/29/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Left vocal cord paralysis (LVCP) is a known complication of patent ductus arteriosus (PDA) surgery in extremely preterm (EP) born neonates; however, consequences of LVCP beyond the first year of life are insufficiently described. Both voice problems and breathing difficulties during physical activity could be expected with an impaired laryngeal inlet. More knowledge may improve the follow-up of EP-born subjects who underwent PDA surgery and prevent confusion between LVCP and other diagnoses. Objectives: Examine the prevalence of LVCP in a nationwide cohort of adults born EP with a history of PDA surgery, and compare symptoms, lung function, and exercise capacity between groups with and without LVCP, and vs. controls born EP and at term. Methods: Adults born EP (<28 weeks' gestation or birth weight <1,000 g) in Norway during 1999-2000 who underwent neonatal PDA surgery and controls born EP and at term were invited to complete questionnaires mapping voice-and respiratory symptoms, and to perform spirometry and maximal treadmill exercise testing. In the PDA-surgery group, exercise tests were performed with a laryngoscope positioned to evaluate laryngeal function. Results: Thirty out of 48 (63%) eligible PDA-surgery subjects were examined at mean (standard deviation) age 19.4 (0.8) years, sixteen (53%) had LVCP. LVCP was associated with self-reported voice symptoms and laryngeal obstruction during exercise, not with lung function or peak oxygen consumption (VO2peak). In the PDA-surgery group, forced expiratory volume in 1 second z-score (z-FEV1) was reduced compared to EP-born controls (n = 30) and term-born controls (n = 36); mean (95% confidence interval) z-FEV1 was -1.8 (-2.3, -1.2), -0.7 (-1.1, -0.3) and -0.3 (-0.5, -0.0), respectively. For VO2peak, corresponding figures were 37.5 (34.9, 40.2), 38.1 (35.1, 41.1), and 43.6 (41.0, 46.5) ml/kg/min, respectively. Conclusions: LVCP was common in EP-born young adults who had undergone neonatal PDA surgery. Within the PDA-surgery group, LVCP was associated with self-reported voice symptoms and laryngeal obstruction during exercise, however we did not find an association with lung function or exercise capacity. Overall, the PDA-surgery group had reduced lung function compared to EP-born and term-born controls, whereas exercise capacity was similarly reduced for both the PDA-surgery and EP-born control groups when compared to term-born controls.

Abstract
In this review, the Paediatric Assembly of the European Respiratory Society (ERS) presents a summary of the highlights and most relevant findings in the field of paediatric respiratory medicine presented at the virtual ERS International Congress 2020. Early Career Members of the ERS and Chairs of the different Groups comprising the Paediatric Assembly discuss a selection of the presented research. These cover a wide range of research areas, including respiratory physiology and sleep, asthma and allergy, cystic fibrosis, respiratory infection and immunology, neonatology and intensive care, epidemiology, bronchology and lung and airway development. Specifically, we describe the long-term effect in lung function of premature birth, mode of delivery and chronic respiratory conditions such as cystic fibrosis. In paediatric asthma, we present risk factors, phenotypes and their progression with age, and the challenges in diagnosis. We confirm the value of the lung clearance index to detect early lung changes in cystic fibrosis. For bronchiectasis treatment, we highlight the importance of identifying treatable traits. The use of biomarkers and genotypes to identify infants at risk of long-term respiratory morbidity is also discussed. We present the long-term impact on respiratory health of early life and fetal exposures to maternal obesity and intrauterine hypoxia, mechanical ventilation hyperoxia, aeroallergens, air pollution, vitamin A deficient intake and bronchitis. Moreover, we report on the use of metabolomics and genetic analysis to understand the effect of these exposures on lung growth and alveolar development. Finally, we stress the need to establish multidisciplinary teams to treat complex airway pathologies.

Abstract
Postnatal ductal closure is stimulated by rising oxygen tension and withdrawal of vasodilatory mediators (prostaglandins, nitric oxide, adenosine) and by vasoconstrictors (endothelin-1, catecholamines, contractile prostanoids), ion channels, calcium flux, platelets, morphologic maturity, and a favorable genetic predisposition. A persistently patent ductus arteriosus (PDA) in preterm infants can have clinical consequences. Decreasing pulmonary vascular resistance, especially in extremely low gestational age newborns, increases left-to-right shunting through the ductus and increases pulmonary blood flow further, leading to interstitial pulmonary edema and volume load to the left heart. Potential consequences of left-to-right shunting via a hemodynamically significant patent ductus arteriosus (hsPDA) include increased risk for prolonged ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis or focal intestinal perforation, intraventricular hemorrhage, and death. In the last decade, there has been a trend toward less aggressive treatment of PDA in preterm infants. However, there is a subgroup of infants who will likely benefit from intervention, be it pharmacologic, interventional, or surgical: (1) prophylactic intravenous indomethacin in highly selected extremely low gestational age newborns with PDA (<26 + 0/7 weeks' gestation, <750 g birth weight), (2) early targeted therapy of PDA in selected preterm infants at particular high risk for PDA-associated complications, and (3) PDA ligation, catheter intervention, or oral paracetamol may be considered as rescue options for hsPDA closure. The impact of catheter-based closure of hsPDA on clinical outcomes should be determined in future prospective studies. Finally, we provide a novel treatment algorithm for PDA in preterm infants that integrates the several treatment modalities in a staged approach.

Abstract
Vocal fold paralysis (VFP) is an important cause of respiratory and feeding compromise in infants. The causes of neonatal VFP are varied and include central nervous system disorders, birth-related trauma, mediastinal masses, iatrogenic injuries, and idiopathic cases. Bilateral VFP often presents with stridor or respiratory distress and can require rapid intervention to stabilize an adequate airway. Unilateral VFP presents more subtly with a weak cry, swallowing dysfunction, and less frequently respiratory distress. The etiology and type of VFP is important for management. Evaluation involves direct visualization of the vocal folds, with additional imaging and testing in select cases. Swallowing dysfunction, also known as dysphagia, is very common in infants with VFP. A clinical assessment of swallowing function is necessary in all cases of VFP, with some patients also requiring an instrumental swallow assessment. Modification of feeding techniques and enteral access for feedings may be necessary. Airway management can vary from close monitoring to noninvasive ventilation, tracheostomy, and laryngeal surgery. Long-term follow-up with otolaryngology and speech-language pathology service is necessary for all children with VFP to ensure adequate breathing, swallowing, and phonation. The short- and long-term health and quality-of-life consequences of VFP can be substantial, especially if not managed early.

Abstract
INTRODUCTION Vocal fold movement impairment (VFMI) is a well-known sequela of cervical and thoracic procedures performed in the vicinity of the recurrent laryngeal nerve. Interpretation of flexible nasolaryngoscopy (FNL) can be difficult in young children due to crying, secretions, and obstructing supraglottic structures. We have previously published on the use of radiologist performed and interpreted, laryngeal ultrasound (LUS) to evaluate vocal fold mobility with substantial agreement with FNL in infants in the cardiovascular intensive care unit. The purpose of this study was to evaluate point of care, clinician performed, LUS for vocal fold mobility in a pediatric voice clinic. METHODS LUS and FNL were performed and recorded on 30 consecutive patients (11 with a clinical diagnosis of VFMI and 19 with clinically normal mobility) in a pediatric voice clinic. All LUS was performed by a single clinician (reviewer 1) with a GE logiq P9 and 12 MHz linear probe. Deidentified recordings of the LUS and FNL (without sound) were reviewed in random order by 2 fellowship trained pediatric otolaryngologists who were blinded to the vocal fold mobility. Cohen's kappa was used to determine agreement. RESULTS There was substantial agreement (κ = 0.7) between the reviewers regarding interpretation of LUS as well as regarding interpretation of FNL κ = 0.7802. In addition, each reviewer had near perfect to substantial agreement between their interpretation of the LUS and FNL (reviewer 1 κ = 0.9294 and reviewer 2 κ = 0.8413). CONCLUSION Point of care, clinician performed, LUS can be used for the identification of VFMI with substantial agreement with FNL with good inter-rater reliability. This provides clinicians with another tool in their armamentarium for the evaluation of challenging larynges.

Abstract
Objective: To investigate voice characteristics and exercise related respiratory symptoms in extremely preterm born 11-year-old children, focusing particularly on associations with management of a patent ductus arteriosus (PDA). Study design: Prospective follow-up of all children born in Norway during 1999-2000 at gestational age <28 weeks or with birthweight <1,000 g. Neonatal data were obtained prospectively on custom-made registration forms completed by neonatologists. Voice characteristics and exercise related respiratory symptoms were obtained at 11 years by parental questionnaires. Result: Questionnaires were returned for 228/372 (61%) eligible children, of whom 137 had no history of PDA. PDA had been noted in 91 participants, of whom 36 had been treated conservatively, 21 with indomethacin, and 34 with surgery. Compared to the children treated with indomethacin or conservatively, the odds ratio (95% confidence interval) for the surgically treated children were 3.4 (1.3; 9.2) for having breathing problems during exercise, 16.9 (2.0; 143.0) for having a hoarse voice, 4.7 (1.3; 16.7) for a voice that breaks when shouting, 4.6 (1.1; 19.1) for a voice that disturbs singing, and 3.7 (1.1; 12.3) for problems shouting or speaking loudly. The significance of surgery per se was uncertain since the duration of mechanical ventilation was associated with the same outcomes. Conclusion: Extremely preterm born children with a neonatal history of PDA surgery had more problems with voice and breathing during exercise in mid-childhood than those whose PDA had been handled otherwise. The study underlines the causal heterogeneity of exercise related respiratory symptoms in preterm born children.

[PMID: 31908731 PMCID: PMC6937415 DOI: 10.4330/wjc.v11.i12.316] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 08/13/2019] [Accepted: 10/18/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Aortic arch stenting is continuously emerging as a safe and effective option to alleviate aortic arch stenosis and arterial hypertension.
CASE SUMMARY We present a 15-year-old girl with aortic arch hypoplasia who had undergone implantation of an uncovered 22 mm Cheatham-Platinum stent due to severe (native) aortic arch stenosis. On follow-up seven months later, she presented a significant re-stenosis of the aortic arch. A second stent (LD Max 26 mm) was implanted and both stents were dilated up to 16 mm. After an initially unremarkable post-interventional course, the patient presented with hoarseness five days after the intervention. MRI and CT scans ruled out an intracranial pathology, as well as thoracic hematoma, arterial dissection, and aneurysm around the intervention site. Laryngoscopy confirmed left vocal fold paresis attributable to an injury to the left recurrent laryngeal nerve (LRLN) during aortic arch stenting, as the nerve loops around the aortic arch in close proximity to the area of the implanted stents. Following a non-invasive therapeutic approach entailing regular speech therapy, the patient recovered and demonstrated no residual clinical symptoms of LRLN palsy after six months.
CONCLUSION Left recurrent laryngeal nerve palsy is a rare complication of aortic arch stenting not previously reported.
