Role of fiberoptic endoscopic evaluation of swallowing (FEES) in children with suspected dysphagia

OBJECTIVE

To assess FEES findings in defining oral feeding safety in children with suspected dysphagia, comparing them with clinical feeding evaluation results.

METHODS

This study comprised a case series involving children with suspected dysphagia, referred for evaluation by otolaryngologists and speech-language pathologists (SLPs) at a Brazilian quaternary public university hospital. These children underwent both clinical evaluations and fiberoptic endoscopic evaluation of swallowing (FEES), with a comprehensive collection of demographic and clinical data. Subsequently, the authors performed a comparative analysis of findings from both assessments.

RESULTS

Most patients successfully completed the FEES procedure (93.7%), resulting in a final number of 60 cases included in the study. The prevalence of dysphagia was confirmed in a significant 88% of these cases. Suspected aspiration on clinical SLP evaluation was present in 34 patients. Of these, FEES confirmed aspiration or penetration in 28 patients. Among the 35 patients with aspiration or penetration on FEES, 7 (20%) had no suspicion on SLP clinical assessment. All seven patients in whom clinical SLP evaluation failed to predict penetration/aspiration had neurological disorders. The median age of the children was 2.8 years, and 49 (81.6%) had neurological disorders, while 35 (58.3%) had chronic pulmonary disease. The most prevalent complaints were choking (41.6%) and sialorrhea (23.3%).

CONCLUSION

FEES can diagnose structural anomalies of the upper aerodigestive tract and significantly contribute to the detection of aspiration and penetration in this group of patients with suspected dysphagia, identifying moderate and severe dysphagia even in cases where clinical assessment had no suspicion.

State of the art in pediatric nanomedicines

In recent years, the continuous development of innovative nanopharmaceuticals is expanding their biomedical and clinical applications. Nanomedicines are being revolutionized to circumvent the limitations of unbound therapeutic agents as well as overcome barriers posed by biological interfaces at the cellular, organ, system, and microenvironment levels. In many ways, the use of nanoconfigured delivery systems has eased challenges associated with patient differences, and in our opinion, this forms the foundation for their potential usefulness in developing innovative medicines and diagnostics for special patient populations. Here, we present a comprehensive review of nanomedicines specifically designed and evaluated for disease management in the pediatric population. Typically, the pediatric population has distinguishing needs relative to those of adults majorly because of their constantly growing bodies and age-related physiological changes, which often need specialized drug formulation interventions to provide desirable therapeutic effects and outcomes. Besides, child-centric drug carriers have unique delivery routes, dosing flexibility, organoleptic properties (e.g., taste, flavor), and caregiver requirements that are often not met by traditional formulations and can impact adherence to therapy. Engineering pediatric medicines as nanoconfigured structures can potentially resolve these limitations stemming from traditional drug carriers because of their unique capabilities. Consequently, researchers from different specialties relentlessly and creatively investigate the usefulness of nanomedicines for pediatric disease management as extensively captured in this compilation. Some examples of nanomedicines covered include nanoparticles, liposomes, and nanomicelles for cancer; solid lipid and lipid-based nanostructured carriers for hypertension; self-nanoemulsifying lipid-based systems and niosomes for infections; and nanocapsules for asthma pharmacotherapy.

Pediatric Esophageal Dysphagia

Swallowing is an elaborate process that requires neuromuscular coordination. Pediatric esophageal dysphagia is broadly categorized into structural and nonstructural causes. The structural causes of pediatric esophageal dysphagia are related to processes that narrow the lumen of the esophagus. Esophageal strictures are the result of scar tissue formation within the lumen of the esophagus, leading to stenosis. Vascular rings and slings cause external compression of the esophagus. Diagnosis requires an esophagram and computed tomography or magnetic resonance imaging. Treatment is guided by the patient's symptoms and underlying diagnosis, although it often requires surgical intervention when symptomatic.

Aspiration pneumonia in nursing literature-a mapping review

Introduction

Aspiration pneumonia (AP) is an infection of the lungs caused by inhalation of material. The reported incidences vary across literature and clinical populations and is associated with high morbidity and mortality. Management of AP is best carried out by a multidisciplinary team.

Methods

This aim of this review was to collate and describe the available evidence on AP to develop a greater understanding of the concept of AP as it is represented in the nursing literature. As a collaborative team, we undertook the six stages of a systematic mapping review. We searched for the term aspiration pneumonia in 200 peer reviewed nursing journals across 10 databases, over a ten-year period (2013-2023).

Results

In this review, 293 papers were coded. Dysphagia, oral health and tube feeding emerged as the most frequent risk factors for AP, and the most reported factors for preventing this condition. Mortality was the most commonly described consequence of AP, followed by hospitalisations and morbidity. Multiple management approaches were reported including dysphagia assessment, risk evaluation, oral care and texture modification of food and fluids. The role of nurses and interprofessional collaborations were described.

Discussion

Despite limited evidence related to the topic of AP in the nursing literature, the complexity of the causes, prevention, management and consequences of AP emerged. Certain factors, such as dysphagia, oral health, and tube feeding, were described under prevention, cause and management of AP. The importance of multidisciplinary approach in the management and prevention of AP was presented.

Surgical Management of Pediatric Obstructive Sleep Apnea Beyond Tonsillectomy & Adenoidectomy: Tongue Base and Larynx

Pediatric patients with persistent obstructive sleep apnea (OSA) after adenotonsillectomy often have additional sites of upper airway obstruction such as the tongue base or larynx. Sleep endoscopy and cross-sectional, dynamic imaging can be used to direct surgical management of persistent OSA. The tongue base is one of the most common sites of obstruction in children with persistent OSA, especially for patients with Trisomy 21. Lingual tonsillectomy, tongue suspension, and/or posterior midline glossectomy may be used to address lingual tonsil hypertrophy and tongue base obstruction. Epiglottopexy and/or supraglottoplasty may be used to address laryngomalacia and epiglottic prolapse resulting in OSA.

Exploring the diagnostic accuracy and applicability of the Gugging Swallowing Screen in children with feeding and/or swallowing disorders

BACKGROUND

The Gugging Swallowing Screen (GUSS) is a bedside dysphagia screening tool that has been designed to determine the risk of aspiration in acute stroke patients. There is no evidence in the literature for the GUSS for the pediatric population. The present study aimed to determine the diagnostic accuracy of GUSS as a screening tool in the Greek language for children with dysphagia.

METHODS

Eighty-Greek-Cypriot children aged 3-12 years who had dysphagia participated in this retrospective study. The translated into Greek GUSS was administered twice (pre- and post-therapy) to each patient throughout 24 sessions of dysphagia therapy.

KEY RESULTS

The GUSS showed a high internal consistency (Cronbach's α = 0.826), good test-retest reliability (rs = 0.767), convergent validity compared to the Greek Pediatric Eating Assessment tool-10 (PEDI-EAT-10) total score (rs = -0.365), and inter-rater reliability (κ = 0.863). A total cutoff points equal to 13.00 was also calculated. Aspiration was identified by the GUSS with low sensitivity and high specificity (PPV 100%, NPV 57%, LR+ NA, LR- 0.79); dysphagia/penetration was identified with high sensitivity and low specificity (PPV 33%, NPV 100%, LR+ 0.102, LR- NA).

CONCLUSIONS & INFERENCES

The pediatric version of GUSS has been found to be a valuable tool in identifying the risk of aspiration as that of adults. It proved to be used as a good screening guide for selecting and confirming the existence of dysphagia from instrumental assessments. This is the first study of the pediatric version of GUSS, and future studies on this topic are needed.

Nutritional Issues in Children with Dysphagia

(1) Background: Pediatric dysphagia presents significant nutritional challenges, often impacting growth and development due to reduced oral intake, increased nutritional needs, and gastrointestinal complications; (2) Methods: This prospective quasi-experimental study assessed 117 children under 14 years old (20 patients were under 1 year old, 80 were aged 1-7 years, and 17 were older than 7 years), diagnosed with swallowing disorders, to analyze their caloric, macro-, and micronutrient intake and identify potential deficiencies. The severity of dysphagia was established using functional oral intake scales, and dietary records were reviewed over a 3-day period; (3) Results: The study revealed that 39.8% of participants did not meet their total energy expenditure (TEE), highlighting a high prevalence of malnutrition among these children. Furthermore, patients using feeding devices exhibited a significantly lower caloric intake, and over half required significantly modified food textures. After individualized speech therapy and nutritional rehabilitation, participants showed significant improvements in caloric intake, with their energy coverage increasing from 958% to 1198% of the daily requirement. Rehabilitation also improved tolerance to a broader range of food textures; (4) Conclusions: This research underscores the importance of multidisciplinary, individualized nutritional strategies to address the specific challenges of pediatric dysphagia, emphasizing the role of enteral nutrition and therapeutic interventions in improving the quality of life and nutritional outcomes of these children. Further studies are recommended to assess the long-term impact of such strategies.

Validation and cross-cultural adaptation of the Italian version of the paediatric eating assessment tool (I-PEDI-EAT-10) in genetic syndromes

BACKGROUND

The Pediatric Eating Assessment Tool (PEDI-EAT-10) is a reliable and valid tool for rapid identification of dysphagia in patients aged 18 months to 18 years.

AIMS

To translate and adapt the PEDI-EAT-10 into the Italian language and evaluate its validity and reliability.

METHODS & PROCEDURES

The translation and cross-cultural adaptation of the tool consisted of five stages: initial translation, synthesis of the translations, back translation, expert committee evaluation and test of the prefinal version. The internal consistency of the translated tool was analysed in a clinical group composed of 200 patients with special healthcare needs aged between 18 months and 18 years. They were consecutively enrolled at the Rare Disease Unit, Paediatrics Department, Fondazione Policlinico Agostino Gemelli-IRCCS, Rome. For test-retest reliability, 50 caregivers filled in the PEDI-EAT-10 questionnaire for a second time after a 2-week period. Construct validity was established by comparing data obtained from patients with data from healthy participants (n = 200). The study was approved by the local ethics committee.

OUTCOMES & RESULTS

Psychometric data obtained from patients (104 M; mean age = 8.08 ± 4.85 years; median age = 7 years) showed satisfactory internal consistency (Cronbach's α = 0.89) and test-retest reliability (Pearson r = 0.99; Spearman r = 0.96). A total of 30% of children were classified as having a high risk of penetration/aspiration. The Italian PEDI-EAT-10 mean total score of the clinical group was significantly different from that resulting from healthy participants.

CONCLUSIONS & IMPLICATIONS

The PEDI-EAT-10 was successfully translated into Italian, validated and found to be a reliable one-page rapid screening tool to identify dysphagia in children and adolescents with special needs.

WHAT THIS PAPER ADDS

What is already known on the subject The PEDI-EAT-10 is a valid and reliable quick discriminative paediatric tool for identifying penetration/aspiration risks. What this paper adds to the existing knowledge In the present study we successfully translated and adapted the PEDI-EAT-10 into the Italian language. What are the potential or actual clinical implications of this work? This translation and adaptation increase access to valid feeding and swallowing assessment for children of Italian-speaking families. In addition, the I-PEDI-EAT-10 can suggest further assessment of patients' swallowing abilities.

Analysis of the Improvement Effect of Combined Application of Oral Rehabilitation Training and Neuromuscular Electrical Stimulation on Pediatric Swallowing Disorders

Pediatric swallowing disorders are common yet often overlooked neuro-muscular system diseases that significantly impact the quality of life and development of affected children. This study aims to explore the effect of combined application of oral rehabilitation training and neuromuscular electrical stimulation on improving pediatric swallowing disorders. Children meeting the inclusion criteria for swallowing disorders were divided into control and experimental groups based on different intervention protocols. The experimental group received combined oral rehabilitation training and neuromuscular electrical stimulation, while the control group received only oral rehabilitation training. Results showed that the intervention was more effective in the experimental group, with shorter recovery time for normal swallowing function and improved nutritional status and quality of life. This study provides scientific evidence for clinical treatment of pediatric swallowing disorders. In conclusion, the combined application of oral rehabilitation training and neuromuscular electrical stimulation effectively improves pediatric swallowing disorders, with superior efficacy compared to single treatment methods. Further research is needed to elucidate the mechanism of action and optimize treatment protocols to enhance the therapeutic outcomes and prognosis of pediatric swallowing disorders.

Translation and validation of traditional Chinese version of the pediatric eating assessment Tool-10

BACKGROUND

/Purpose: The Pediatric Eating Assessment Tool-10 (Pedi-EAT-10) is a caregiver-administrated subjective questionnaire for evaluating swallowing and feeding disorders among children. This study translated the Pedi-EAT-10 into Traditional Chinese and tested the translated version's reliability and validity.

METHODS

Pedi-EAT-10 was translated into Traditional Chinese by experts and finalized after discussion and testing. A total of 168 participants, consisting of 32 children with dysphagia from a tertiary medical center and 136 healthy controls from its Children Care Center for Employees, were recruited. All participants were assessed by an otolaryngologist and speech-language pathologist. The reliability, validity, and efficacy of the translated Pedi-EAT-10 were analyzed to ensure it could be used to identify pediatric dysphagia and feeding problems.

RESULTS

The Traditional Chinese version of the Pedi-EAT-10 had significant clinical discriminative validity between the dysphagia group and the control group (total score = 9.6 vs. 2.6, P < 0.001), acceptable test-retest reliability (intraclass correlation = 0.63), and excellent internal consistency (Cronbach's α = 0.91 for the entire cohort). The overall performance of the test for distinguishing children with dysphagia from normal controls was acceptable, and the area under the curve was 74.8% (sensitivity = 71.9%; specificity = 69.9%). The optimal cutoff score was ≥3 on the Youdex index.

CONCLUSIONS

The Traditional Chinese version of the Pedi-EAT-10 has fair reliability and validity and can be quickly and easily completed by caregivers. The translated Ped-EAT-10 can be used as a first-line tool for assessing the need for further referral and instrumental examination.

What School-Based Speech-Language Pathologists Need to Know About Pediatric Swallowing and Feeding Development and Disorders

PURPOSE

School-based speech-language pathologists are at the frontline for treating children with pediatric feeding disorders (PFDs). Often, speech-language pathologists are the primary allied health professionals who are charged with maximizing safety, supporting nutrition and neurodevelopmental growth. Due to the increasing need for assessment and treatment of PFDs in schools, it is fundamental that PFDs and dysphagia are detected, differentially diagnosed, and addressed to support developing children. This tutorial addresses the anatomy, physiology, and development of functional feeding and swallowing patterns across the spectrum of childhood for both PFDs and dysphagia.

METHOD

A clinical expert review of the anatomy, physiology, and development of functional feeding and swallowing patterns in children across the spectrum of childhood will be completed.

CONCLUSIONS

The aim of this tutorial is to support school-based speech-language pathologists in their understanding of the anatomy and physiology of feeding and swallowing. School-based speech-language pathologists should complete this tutorial with an increased understanding and breadth of knowledge related to typical anatomy and physiology versus atypical or disordered presentations. This tutorial would support school-based speech-language pathologists in determining whether a child presents with characteristics of oropharyngeal dysphagia and/or a PFD.

Airway and Swallowing Outcomes in Children With Combined Laryngomalacia and Laryngeal Cleft

Laryngomalacia (LM) and laryngeal cleft (LC) can independently cause dysphagia but rarely can occur concomitantly. We discuss the presentation, decision-making, and swallow outcomes following surgical correction of combined LM and LC. We present four patients with combined LM and an LC who underwent both primary supraglottoplasty (SGP) and laryngeal cleft repair (LCR). Each patient presented with recurrent choking or coughing with feeds. Stridor was only present in two patients. Patients with SGP saw the resolution of stridor when present, but dysphagia persisted in all four cases. LCR clinically and objectively resolved all symptoms of dysphagia. We found that flexible fiberoptic laryngoscopy is not always reliable at detecting combined pathology. Patients presenting with persistent dysphagia following SGP should be suspected of having interarytenoid pathology. We recommend a staged surgical approach with SGP before LCR.

Clinical outcomes before and after videofluoroscopic swallow study in children 24 months of age or younger

OBJECTIVE

To evaluate the combined impact of videofluoroscopic swallow study (VFSS) and therapeutic feeding and swallowing interventions on clinical outcomes in children with oropharyngeal dysphagia (OPD).

METHODS

This was an uncontrolled longitudinal analytical study in which OPD patients were evaluated before and after VFSS. Children ≤ 24 months of age diagnosed with OPD in a clinical setting and undergoing VFSS for investigation and management of OPD were included in the study. The study participants received therapeutic feeding and swallowing interventions after having undergone VFSS, being followed at an outpatient clinic for pediatric dysphagia in order to monitor feeding and swallowing difficulties. Respiratory and feeding outcomes were compared before and after VFSS.

RESULTS

Penetration/aspiration events were observed in 61% of the VFSSs (n = 72), and therapeutic feeding and swallowing interventions were recommended for 97% of the study participants. After the VFSS, there was a reduction in the odds of receiving antibiotic therapy (OR = 0.007) and in the duration of antibiotic therapy (p = 0.014), as well as in the odds of being admitted to hospital (p = 0.024) and in the length of hospital stay (p = 0.025). A combination of oral and enteral feeding became more common than oral or enteral feeding alone (p = 0.002).

CONCLUSIONS

A high proportion of participants exhibited penetration/aspiration on VFSS. Therapeutic feeding and swallowing interventions following a VFSS appear to be associated with reduced respiratory morbidity in this population.

Validation and cultural adaptation of a Greek Version of Pediatric Eating Assessment Tool 10 (PEDI - EAT - 10) in Greek-Cypriot Parents

PURPOSE

The Pediatric Eating Assessment Tool (PEDI-EAT-10) is a parents/caregivers screening tool that assesses pediatric patients at risk of penetration and/or aspiration symptoms. The aim of this study was the validation of PEDI-EAT-10 in the Greek language.

MATERIALS AND METHODS

This cross-sectional study included 222 parents/caregivers of children with (n = 122) and without (n = 100) feeding and/or swallowing disorders, with age range 3 - 12 years. The children were selected from Cypriot schools and health settings. All parents filled out the PEDI-EAΤ-10 questionnaire and after its initial completion, it was re-administered after 2 weeks.

RESULTS

A statistically significant difference was observed in the PEDI-EAT-10 total mean scores between the study's two groups [t (220) = 9.886, p < 0.001]. Internal consistency was high (Cronbach's alpha= 0.801) with very good split-half reliability equal to 0.789. A significant and strong test-retest reliability was computed (r = 0.998, p < 0.001). The PEDI-EAT-10 cutoff point was 11.00 (AUC: 0.869, p < 0.001) for children with feeding and/or swallowing disorders in accordance with the PAS scale.

CONCLUSIONS

In conclusion, the Greek version of PEDI-EAT-10 is shown to be a valid and reliable screening tool for the assessment of the pediatric population with a risk of dysphagia.

Flexible bronchoscopy findings and management impact in children with oropharyngeal dysphagia

INTRODUCTION

Flexible bronchoscopy (FB) and bronchoalveolar lavage (BAL) are frequently performed in children with known or suspected aspiration, however, the additive value of FB in conjunction with direct laryngoscopy and rigid bronchoscopy (DLB) has not been previously quantified. This study details the common endoscopic/cytological findings and associated management impact of FB and BAL in pediatric Aerodigestive patients undergoing combined airway evaluation (FB and DLB) for oropharyngeal dysphagia.

MATERIALS AND METHODS

A retrospective chart review was performed in children <3 years of age followed through a large Aerodigestive center undergoing outpatient, combined airway endoscopy for dysphagia. Patient and procedural characteristics, endoscopic and BAL findings, and management metrics were collected and analyzed. A secondary analysis evaluated the association between endoscopic findings and medication changes.

RESULTS

Ninety-one procedures (median patient age, 15 months) were identified. All procedures included both FB and DLB, and just over half (52.7%) included esophagogastroduodenoscopy. Common endoscopic findings included bronchitis (73.6%), adenoidal hypertrophy (31.9%), and tracheomalacia (10.8%). BAL cytology frequently identified neutrophilic inflammation (mean 39.6% neutrophils [interquartile range 6.5%-71%)]. Cultured pathogens commonly included Streptococcus viridans (46.6%), Hemophilus influenzae (36.3%), Moraxella catarrhalis (30.1%), and Streptococcus pneumoniae (25.0%). FB and BAL results contributed to clinical decisions in 65 of 91 (71.4%) patients. Endoscopically-diagnosed bronchitis (odds ratio [OR] 7.27, 95% confidence interval [CI] 2.4-21.99) and tracheomalacia (OR 5.79, 95% CI 1.20-27.85) were significantly associated with increased odds of medication adjustments following FB.

CONCLUSION

In pediatric Aerodigestive patients undergoing combined airway evaluation for oropharyngeal dysphagia, FB and BAL are high-yield and clinically impactful procedures.

Post-extubation dysphagia in pediatric trauma patients: a single-center case-series study

We aimed to investigate whether ventilator support time influences the occurrence of dysphagia in pediatric trauma patients. This case-series study was conducted in a single pediatric emergency and critical care center from April 2012 to March 2022. Trauma patients aged < 16 years who underwent tracheal intubation were divided into two groups based on the occurrence of dysphagia within 72 h after extubation, and their data were analyzed. Tracheal intubation was performed in 75 pediatric trauma patients, and 53 of them were included in the analysis. A total of 22 patients had post-extubation dysphagia and head trauma. The dysphagia group tended to have more severe head injuries (Abbreviated Injury Scale (AIS) 4 [4-5] vs. 4 [0-4]; p < 0.05), a longer ventilator support time (7 days [4-11] vs. 1 day [1-2.5]; p < 0.05), and a longer length of hospital stay (27 days [18.0-40.3] vs. 11 days [10.0-21.0]; p < 0.05). Severe head trauma and a long duration of tracheal intubation may be risk factors for dysphagia in pediatric trauma patients. Therefore, early recognition of these risk factors could assist in treatment planning for speech-language pathologist intervention and nutritional routes of administration.

Swallowing Function After Epiglottopexy in Children

OBJECTIVE

Epiglottopexy has been an increasingly utilized intervention in children with epiglottic prolapse and airway obstruction. Given the role of the epiglottis in protecting the airway during swallowing and the potential effect of repositioning the epiglottis on the passage of the bolus, we aimed to compare swallowing outcomes before and after epiglottopexy in children.

STUDY DESIGN

A retrospective cohort study.

SETTING

Tertiary care children's hospital.

METHODS

Data were extracted from charts of children who underwent epiglottopexy and had a subsequent instrumental swallowing evaluation between January 2018 and September 2022.

RESULTS

A total of 93 patients underwent epiglottopexy. Of these, 38 patients met inclusion requirements. The mean age at surgery was 41 ± 47 months. Most patients (n = 37, 97.4%) had significant comorbidities such as secondary airway lesions (n = 33, 91.7%), a genetic or syndromic disorder (n = 25, 69.4%), and dysphagia (n = 29, 76.3%). All patients had a concurrent procedure at the time of epiglottopexy with supraglottoplasty (n = 24, 63.2%) and lingual tonsillectomy (n = 16, 42.1%) being the most common. No changes in initiation or patterns of swallowing were noted postoperatively. A total of 7 (18.4%) patients had worsening swallow function: 2 had new-onset dysphagia, and 5 had worsening pre-existing dysphagia. Liquid or food textures penetrated remained unchanged or improved in most cases. No risk factors for worsening dysphagia were identified in our cohort.

CONCLUSION

Children with medical comorbidities undergoing epiglottopexy with additional airway interventions may experience new or worsening dysphagia. However, the procedure is generally safe without notable patterned changes in the swallowing mechanism.

Current opinion in otolaryngology and head and neck surgery: the role of the otolaryngologist in the management of pediatric dysphagia

PURPOSE OF REVIEW

Dysphagia affects at least 1% of the pediatric population. This prevalence further increases in patients who are born prematurely or who have underlying neuromuscular or cardiopulmonary disorders. A multidisciplinary team approach, including an Otolaryngologist, can help promote an expedited diagnosis and therapeutic regimen, ensuring that the patient receives adequate nutrition needed for growth and development.

RECENT FINDINGS

The development and growth of multidisciplinary aerodigestive clinics have improved outcomes in pediatric patients with dysphagia. If a structural concern is noted on examination, there remain a multitude of medical and surgical options to help improve patient outcomes and swallow. These treatment options are usually multimodality and specific interventions may be employed to target a specific and notable abnormality.

SUMMARY

Pediatric dysphagia is a complex concern. For the otolaryngologist, etiologies with surgical targets may include ankyloglossia, tonsillar hypertrophy, laryngomalacia, laryngo-esophageal cleft, vocal fold movement impairment, and cricopharyngeal achalasia. The development and formalization of a multidisciplinary approach has streamlined and broadened treatment options for these patients. An otolaryngologist is integral as part of the treatment team of these patients.

Comprehensive Manometric Evaluation of Dysphagia in Patients with Down Syndrome

Dysphagia is a common symptom in children with Down syndrome and is conventionally evaluated with imaging and endoscopy; high-resolution manometry is not routinely utilized. The aim of this study was to describe and correlate pharyngeal and esophageal manometry findings with contrast studies and endoscopy in patients with Down syndrome and dysphagia. Electronic medical records of patients with Down syndrome with dysphagia seen at our center between January 2008 and January 2022 were reviewed. Data collected included demographics, co-morbidities, symptoms, imaging, endoscopy, and manometry. Twenty-four patients with Down syndrome [median age of 14.9 years (IQR 7.6, 20.5), 20.8% female] met inclusion criteria. Common presenting symptoms of dysphagia included vomiting or regurgitation in 15 (62.5%) patients, and choking, gagging, or retching in 10 (41.7%) patients. Esophageal manometry was abnormal in 18/22 (81.2%) patients. The most common findings were ineffective esophageal motility in 9 (40.9%) followed by esophageal aperistalsis in 8 (36.4%) patients. Rumination pattern was noted in 5 (22.8%) patients. All 6 (25%) patients who previously had fundoplication had esophageal dysmotility. Strong agreement was noted between upper gastrointestinal studies and high-resolution esophageal manometry (p = 1.0) but no agreement was found between pharyngeal manometry and video fluoroscopic swallow studies (p = 0.041). High-resolution pharyngeal and esophageal manometry provide complementary objective data that may be critical in tailoring therapeutic strategies for managing patients with Down syndrome with dysphagia.

Initial evaluation of a multidisciplinary pediatric aerodigestive program in a Brazilian hospital: challenges and mitigation strategies

OBJECTIVE

To identify clinical and epidemiological characteristics of children evaluated by the pediatric aerodigestive program at the beginning of its activity, describe challenges in follow-up, and suggest mitigation strategies.

METHODS

A case series was conducted describing the first 25 patients discussed by the aerodigestive team from a Brazilian quaternary public university hospital between April 2019 and October 2020. The median follow-up was 37 months.

RESULTS

During the study period 25 children were seen by the group and the median age at first assessment was 45.7 months old. Eight children had a primary airway abnormality, five had a tracheostomy. Nine children had genetic disorders and one had esophageal atresia. Dysphagia was present in 80% of the patients, 68% had a history of chronic or recurrent lung disease, 64% had a gastroenterological diagnosis and 56% had neurological impairment. Moderate to severe dysphagia was identified in 12 children and 7 of these had an exclusive oral diet at the time. The majority of children (72%) had 3 or more comorbidities. Following team discussion, a change in feeding strategy was suggested in 56% of the children. The most frequently ordered exam was pHmetry (44%) and gastrostomy was the surgical procedure with the longest waiting list.

CONCLUSIONS

Dysphagia was the most frequent issue encountered in this initial group of aerodigestive patients. Pediatricians caring for these children must be involved in aerodigestive team discussions and hospital policies must be revised to facilitate access to exams and procedures needed for this population.

Arteria Lusoria as a Cause of Dysphagia in an Infant

The aberrant right subclavian artery (i.e., arteria lusoria) arising from the left part of the aortic arch is a rare congenital anomaly. In some patients, esophageal compression may cause symptoms of dysphagia, also called dysphagia lusoria. It can cause serious feeding disorders and poor weight gain in young children. We present the case of an early onset of dysphagia lusoria in a 1-month-old girl whose clinical diagnosis was confirmed by esophagography and magnetic resonance imaging. This kind of vascular anomaly can present a diagnostic challenge and should be considered in diagnosing dysphagia in childhood.

Correlation Between Clinical Characteristics and Radionuclide Salivagram Findings in Infants With Congenital Laryngeal Developmental Anomalies

OBJECTIVE

To evaluate the correlation between clinical characteristics and radionuclide salivagram findings in infants with congenital laryngeal developmental anomalies, and determine the clinical characteristics that could predict the positive results of radionuclide salivagram.

METHODS

151 hospitalized infants with congenital laryngeal developmental anomalies were retrospectively included to assess the correlation between positive radionuclide salivagram results and clinical features, and a multivariate logistic regression model was constructed to identify significant correlates that jointly predict positive radionuclide salivagram results.

RESULTS

Positive radionuclide salivagram results were significantly associated with fever, neurological diseases, congenital syndromes, and positive pathogenetic test results in univariate analysis. Positive radionuclide salivagram were significantly associated with fever (odds ratio [OR] = 3.494; 95% confidence interval [CI] 1.414-8.630; P = 0.007), neurological diseases (OR = 3.296; 95% CI 1.335-8.138; P = 0.010), and congenital syndromes (OR = 5.069, 95% CI 1.696-15.154; P = 0.004) in a multivariable logistic regression analysis.

CONCLUSION

Fever, concurrent neurological diseases, and concurrent congenital syndromes were discovered as clinical factors that could predict positive radionuclide salivagram results and salivary aspiration should be highly suspected in infants with these clinical factors of congenital laryngeal developmental anomalies.

Dysphagia Outcomes Before and After Adenotonsillectomy in Children With Obstructive Sleep Apnea: A Secondary Analysis of a Randomized Clinical Trial

Importance

Obstructive sleep apnea (OSA) and tonsil hypertrophy may be associated with dysphagia. However, randomized clinical trials assessing dysphagia outcomes in children randomized to adenotonsillectomy (AT) vs watchful waiting with supportive care (WWSC) are lacking.

Objective

To assess dysphagia outcomes in children with OSA and tonsil hypertrophy managed with AT or WWSC.

Design, Setting, and Participants

This secondary analysis of a multicenter randomized clinical trial, the Childhood Adenotonsillectomy Trial (CHAT), was conducted at tertiary children's hospitals from October 2007 to June 2012. Children aged 5.0 to 9.9 years with OSA were randomized to AT or WWSC and underwent polysomnography at baseline and 7 months. Caregivers completed the OSA-18 questionnaire, which includes an item on difficulty in swallowing at baseline and 7 months. The current secondary analysis was conducted from December 1, 2022, to January 10, 2023.

Interventions

AT vs WWSC.

Main Outcomes and Measures

Prevalence of dysphagia, based on parental responses to the difficulty in swallowing item on the OSA-18 questionnaire, was redefined as a binary outcome at baseline and 7-month follow-up.

Results

In total, 386 children were included (199 female [51.6%]; median [IQR] age, 6.0 [5.0-8.0] years). Of the total, 207 children were Black (53.6%). At baseline, the number of children with dysphagia was similar (4.0%; 95% CI, -4.9% to 12.9%) between the AT group (56 [29.8%]) and the WWSC group (51 [25.8%]). Following AT, a decrease was observed (21.3%; 95% CI, 13.5%-28.9%) in the prevalence of dysphagia among the children. In contrast, the prevalence of dysphagia did not change significantly (1.0%; 95% CI, -7.6% to 9.6%) in the WWSC group. Children in the AT group were more likely to experience a resolution of dysphagia than those in the WWSC group (adjusted odds ratio, 4.84; 95% CI, 1.91-12.25). Higher baseline AHI was associated with a lower resolution of dysphagia (AOR, 0.91; 95% CI, 0.83-0.98).

Conclusions and Relevance

This secondary analysis of the CHAT randomized clinical trial suggested that children with dysphagia and OSA undergoing AT may experience dysphagia improvement. A prospective randomized trial that uses a validated dysphagia survey is needed to verify the effectiveness of AT in treating dysphagia.

Quantifying the Healthcare Burden of Pediatric Feeding Disorder after Congenital Heart Surgery

OBJECTIVE

To determine the healthcare costs and use burden of pediatric feeding disorder after congenital heart surgery.

STUDY DESIGN

A retrospective, population-based cohort study using claims data (2009-2018) was performed. Participants include patients aged 0-18 years who had undergone congenital heart surgery and were included in the insurance database ≥1 year after surgery. The main exposure variable was the presence of a pediatric feeding disorder, defined as a need for a feeding tube at discharge or diagnosis of dysphagia or feeding-related difficulty within the study timeframe. Main outcomes include overall and feeding-related medical care use, defined as readmissions and outpatient use, and feeding-related cost of care within 1 year of surgery.

RESULTS

A total of 10 849 pediatric patients were identified, with 3347 (30.9%) presenting with pediatric feeding disorder within 1 year of surgery. Patients with pediatric feeding disorder spent a median of 12 days (IQR, 6-33 days) in the hospital, compared with 5 days (IQR, 3-8 days) in patients without (P < .001). Rate ratios for overall readmissions, feeding-related readmissions, feeding-related outpatient use, and cost of care over the first year after surgery were significantly increased at 2.9 (95% CI, 2.5-3.4), 5.1 (95% CI, 4.6-5.7), 7.7 (95% CI, 6.5-9.1), and 2.2 (95% CI, 2.0-2.3) among patients with pediatric feeding disorder as compared with those without.

CONCLUSIONS

Pediatric feeding disorder after congenital heart surgery is associated with a significant healthcare burden. Multidisciplinary care for and research on this health condition is needed to identify optimal management strategies to reduce this burden and improve outcomes.

Airway clearance in patients with neuromuscular disease

Airway clearance is a critical component of both maintenance of respiratory health and management of acute respiratory illnesses. The process of effective airway clearance begins with the recognition of secretions in the airway and culminates in expectoration or swallowing. There are multiple points on this continuum at which neuromuscular disease causes impaired airway clearance. This can result in an otherwise mild upper respiratory illness progressing unabated from an easily managed condition to a severe, life-threatening lower respiratory illness requiring intensive therapy for patient recovery. Even during periods of relative health, airway protective mechanisms can be compromised, and patients may have difficulty managing average quantities of secretions. This review summarizes airway clearance physiology and pathophysiology, mechanical and pharmacologic treatment modalities, and provides a practical approach for managing secretions in patients with neuromuscular disease. Neuromuscular disease is an umbrella term used to describe disorders that involve dysfunction of peripheral nerves, the neuromuscular junction, or skeletal muscle. Although this paper specifically reviews airway clearance pertaining to those with neuromuscular diseases (e.g., muscular dystrophy, spinal muscular atrophy, myasthenia gravis), most of its content is relevant to the management of patients with central nervous system disorders such as chronic static encephalopathy caused by trauma, metabolic or genetic abnormalities, congenital infection, or neonatal hypoxic-ischemic injury.

A Prospective Study of Parental Experience with Thickening Feeds for Children with Oropharyngeal Dysphagia and Gastroesophageal Reflux

Thickening is efficacious and commonly recommended for oropharyngeal dysphagia and gastroesophageal reflux. Little is known about parental experience with this practice. Results of this cross-sectional questionnaire study suggest attitudes are positive, but parents frequently adjust recipes/nipple sizes, which might increase aspiration risk. Clinical follow-up is essential to ensure safe feeding.

Timeline to dysphagia resolution after endoscopic intervention of an interarytenoid defect based on Video Fluoroscopic Swallow Study dysphagia severity

INTRODUCTION

We previously reported that endoscopic repair of a Type 1 Laryngeal Cleft (LC1) or Deep Interarytenoid Groove (DIG) improves swallowing function postoperatively. However, caregivers often ask about the timeline to resolution of the need for thickening. This study re-examines this cohort to answer this important caregiver-centered question.

METHODS

We reassessed a 3-year retrospective, single-center dataset of children with dysphagia found to have a LC-1 or DIG on endoscopic exam. The primary outcome was rate of complete resolution of dysphagia at 2, 6, and 12 months after endoscopic intervention. A sub-group analysis was made based on severity of dysphagia prior to intervention and by type of endoscopic repair.

RESULTS

Thirty-nine patients with mean age 1.35 years that had a LC-1 or DIG met criteria for inclusion. Rate of complete dysphagia resolution increased over time. Those with mild dysphagia (flow-reducing nipple and/or IDDSI consistency 1 or 2) had brisker resolution than those with moderate dysphagia (IDDSI consistency 3 or 4) at 2 months (67% vs 5%, p < 0.01) and at 6 months (80% vs 18%, p < 0.01) after endoscopic repair. There was no difference in dysphagia resolution between patients grouped by type of endoscopic repair.

CONCLUSION

Addressing an interarytenoid defect in patients will not result in immediate, complete dysphagia resolution in most patients. However, patients that only require a flow-reducing nipple and/or thickening to an IDDSI consistency 1 or 2 have brisker resolution of the need for thickening than those that require an IDSSI consistency 3 or 4 prior to intervention. These results inform pre-operative discussions of the timeline to resolution based upon severity of dysphagia and help manage caregiver expectations.

Laryngeal Penetration and Risk of Aspiration Pneumonia in Children with Dysphagia-A Systematic Review

This study was a systematic review and meta-analysis that assessed the risk of aspiration pneumonia in children with laryngeal penetration or tracheal aspiration via a video-fluoroscopic study (VFSS) and compared the results to those for children with neither condition. Systematic searches were conducted using databases, including PubMed, Cochrane Library, and Web of Science. Meta-analysis was used to obtain summary odds ratios (OR) and 95% confidence intervals (CI). The overall quality of evidence was assessed using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. In total, 13 studies were conducted with 3159 participants. Combined results from six studies showed that laryngeal penetration on VFSS may be associated with aspiration pneumonia compared to no laryngeal penetration; however, the summary estimate was imprecise and included the possibility of no association (OR 1.44, 95% CI 0.94, 2.19, evidence certainty: low). Data from seven studies showed that tracheal aspiration might be associated with aspiration pneumonia compared to no tracheal aspiration (OR 2.72, 95% CI 1.86, 3.98, evidence certainty: moderate). The association between aspiration pneumonia and laryngeal penetration through VFSS seems to be weaker than that for tracheal aspiration. Prospective cohort studies with clear definitions of laryngeal penetration and that measure clinical and patient reported outcomes are needed to further define the association between laryngeal penetration and aspiration pneumonia.

Aspiration in the First Year of Life and Later Tube Feeding: A Retrospective Cohort from a Low-Income Country

The objective of this study is to investigate in infants submitted to videofluoroscopic swallowing study (VFSS) during the first year of life, the association between aspiration and later tube feeding, and to identify potential risk factors related to feeding route outcome. Retrospective cohort study with data from electronic health records was performed. Data were collected from infants < 12 months of age who underwent VFSS during inpatient hospital stay in the period between 2013 and 2018. Patient charts after 24 months of age were reviewed to ascertain the outcome and study factors, including VFSS findings, neonatal data, clinical comorbidities, nutritional status, ICU admissions, and hospital readmissions. Relative risk (RR) for tube feeding was calculated, and a Poisson regression with robust variance was used to identify potential risk factors. VFSS data from 164 patients < 1 year old were retrieved, of whom 112 (68%) contributed with data about feeding route after 2 years of age. Most infants were preterm < 37 weeks (66%), with a median age of 9.28 weeks at the time of the exam. Aspiration occurred in 33% of the patients, with no statistically significant difference between full-term or premature infants (p = 0.173). The relative risk of tube feeding after the age of 2 among infants who aspirated in VFSS was 0.74 (CI 0.25-2.16, p = 0.573). Poisson regression analysis showed that number of hospital readmissions (RR 1.04, 95%CI 1.01-1.07, p = 0.005) and gestational age < 34 weeks (RR 0.26, 95%CI 0.07-0.089, p = 0.032) were associated with later tube feeding. Early VFSS findings have low predictive value regarding later feeding route. Aspiration events should be considered as complementary information for clinical decision.

Importance of feeding status evaluation in older patients undergoing hemodialysis

Older hospitalized patients undergoing hemodialysis are increasingly experiencing malnutrition caused by dysphagia. However, only a few studies have focused on this problem. We used the Kuchikara Taberu Balance Chart (KTBC) to evaluate the patients' feeding status and examined its association with their nutritional status and prognosis. This study included elderly patients undergoing hemodialysis who were hospitalized at Nagasaki Renal Center for > 3 days between June 2021 and February 2022. In total, 82 inpatients were included [mean age, 73.4 ± 10.0 years; men, 57.3%; median dialysis vintage, 79.0 months (interquartile range, 37.3-164.8)]. We classified patients with lower than the median KTBC score (57 points) as being at risk for dysphagia; 37 patients (45.1%) were at risk for dysphagia. Spearman's rank correlation coefficient (ρ) elucidated that the KTBC total score was significantly associated with each nutritional indicator [serum albumin level (ρ = 0.505, p < 0.001); geriatric nutritional risk index (ρ = 0.600, p < 0.001); and nutritional risk index (ρ = -0.566, p < 0.001)]. The KTBC score was also closely associated with the body mass index (ρ = 0.228, p = 0.04). Patients with a lower KTBC score showed poor prognosis (log-rank test: p = 0.001), and age- and sex-adjusted Cox proportional analysis showed that the KTBC score was associated with life prognosis (hazard ratio, 0.90; 95% confidential interval, 0.86-0.94; p < 0.001). Therefore, we concluded that the patients at risk of dysphagia, identified using the KTBC score, were malnourished and had a poor prognosis. Hence, the evaluation of dysphagia using the KTBC is encouraged to prevent malnutrition in vulnerable older patients undergoing hemodialysis.

Lipid‐Laden Macrophage Index as a Diagnostic Tool for Pediatric Aspiration: A Systematic Review

Objective

Lipid-laden macrophage index (LLMI) has been proposed as a marker for aspiration on bronchoalveolar lavage. It has also been studied as a marker for gastroesophageal reflux and other pulmonary diseases. This review aims to determine the clinical correlation between LLMI and pediatric aspiration.

Data Sources

PubMed (MeSH search), Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) portals through December 17th, 2020.

Review Methods

Preferred Reporting Items for Systematic Review and Meta-Analysis criteria were followed, and a quality assessment of included studies was performed using the Methodological Index for Non-Randomized Studies. Search criteria included all occurrences in the title or abstract of the terms "pulmonary aspiration" and "alveolar macrophages."

Results

Five studies describing 720 patients met inclusion, 3 retrospective case-control studies, and 2 prospective observational studies. Four studies suggested a link between elevated LLMI and aspiration, and 1 found no association. Control groups varied and included healthy nonaspirators to nonaspirators with other pulmonary diseases. Diagnosis of aspiration was not standardized across the studies. Three papers proposed cutoff values for LLMI, all different.

Conclusion

The existing literature indicates that LLMI is not a sensitive or specific marker for aspiration. Further study is needed to define the utility of LLMI in pediatric aspiration.

Management of Children with Swallowing Problems: New Advances in Paediatric Thickeners

A satellite symposium on the evaluation and management of dysphagia in children was held during the 12th Annual Congress of the European Society for Swallowing Disorders (ESSD) in Leuven, Belgium, on 14th September 2022. Dysphagia is the impairment or difficulty in swallowing and may have an oropharyngeal or oesophageal cause. This can result in delayed transit of liquids or solid food from the mouth to the stomach. Food thickening agents can reduce regurgitation and improve swallowing mechanics, particularly in infants and young children. At this symposium, Karen van Hulst, Speech and Language Therapist and Clinical Epidemiologist at Radboud University Medical Center, Amalia’s Children’s Hospital, the Netherlands, introduced the topic of dysphagia and its complications, and the evaluation of dysphagia. She then discussed the use of thickening agents in children with dysphagia. Ben Hanson from the Department of Engineering, University College London, UK, introduced the International Dysphagia Diet Standardization Initiative (IDDSI). The IDDSI has developed a standardised and practical method of measuring the thickness of liquid and food that can be used when preparing foods at home or in the hospital, and may be applied commercially. Analou Sugar, Clinical Lead in Paediatric Speech and Language Therapy at Chelsea and Westminster Hospital Foundation Trust, London, UK, ended the symposium with a presentation of her recent clinical experience using a new thickener (ThickenUp® Junior, Nestlé Health Science, Vevey, Switzerland) in paediatric patients.

Pediatric dysphagia overview: best practice recommendation study by multidisciplinary experts

BACKGROUND

Currently, there is no comprehensive and multidisciplinary recommendation study covering all aspects of pediatric dysphagia (PD). This study aimed to generate PD management recommendations with methods that can be used in clinical practice to fill this gap in our country and in the world, from the perspective of experienced multidisciplinary experts.

METHODS

This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-round modified Delphi survey via e-mail. First, ten open-ended questions were created, and then detailed recommendations including management, diagnosis, treatment, and follow-up were created with the answers from these questions. Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation) and divergent consensus (not recommended).

RESULTS

In the 1st Delphi round, a questionnaire of 414 items was prepared based on the experts' responses to ten open-ended questions. In the 2nd Delphi round, 59.2% of these items were accepted as pre-recommendation. In the 3rd Delphi round, 62.6% of 246 items were accepted for inclusion in the proposals. The final version recommendations consisted of 154 items.

CONCLUSIONS

This study includes comprehensive and detailed answers for every problem that could be posed in clinical practice for the management of PD, and recommendations are for all pediatric patients with both oropharyngeal and esophageal dysphagia.

The Quality, Reliability, and Accuracy of Videos Regarding Exercises and Management for Dysphagia in Pediatric Populations Uploaded on YouTube

Objectives: YouTube is well known for providing easy access to various kinds of video content. In this study, we investigated the quality and reliability of videos on YouTube addressing exercise or dysphagia management in the pediatric population. Methods: Video quality and reliability were assessed by using the Global Quality Scale (GQS) and a modified DISCERN tool, respectively. The accuracy of the information in each video was also evaluated. Other information, including the video source, length, date of upload, as well as the number of views, likes, dislikes, and comments were investigated, and statistical significance was determined. Results: In total, 22 videos on exercises and dysphagia management in pediatric populations were evaluated; 36.4% and 72.7% of these videos did not have high quality or reliability, respectively. Moreover, half of the videos did not contain accurate information. Even when videos were created by medical specialists, many of these YouTube videos were of low quality, reliability, and accuracy. Conclusions: The reliability, quality, and accuracy of many videos on exercise or dysphagia management in the pediatric population were low. Video creators, especially medical specialists, should strive to create videos with high quality, reliability, and accuracy.

Quantitative Measurement of Swallowing Performance Using Iowa Oral Performance Instrument: A Systematic Review and Meta-Analysis

Swallowing is a complex but stereotyped motor activity aimed at serving two vital purposes: alimentary function and the protection of upper airways. Therefore, any impairment of the swallowing act can represent a significant clinical and personal problem that needs an accurate diagnosis by means of reliable and non-invasive techniques. Thus, a systematic review and meta-analysis was performed to investigate the reliability of the Iowa Oral Pressure Instrument (IOPI) in distinguishing healthy controls (HC) from patients affected by swallowing disorders or pathologies and conditions that imply dysphagia. A comprehensive search was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and using PubMed, Scopus, Web of Science, Cochrane, and Lilacs databases. Overall, 271 articles were identified and, after a three-step screening, 33 case-control and interventional studies reporting IOPI measurements were included. The methodological quality of the retrieved studies resulted in being at a low risk of bias. The meta-analysis on case-control studies showed that maximum tongue pressure (MIP) values were always higher in HC than in patients, with an overall effect of the MIP difference of 18.2 KPa (17.7–18.7 KPa CI). This result was also confirmed when the sample was split into adults and children, although the MIP difference between HC and patients was greater in children than in adults (21.0 vs. 15.4 KPa in the MIP mean difference overall effect, respectively). Tongue endurance (TE) showed conflicting results among studies, with an overall effect among studies near zero (0.7 s, 0.2–1.1 s CI) and a slight tendency toward higher TE values in HC than in patients. Among the intervention studies, MIP values were higher after treatment than before, with a better outcome after the experimental tongue training exercise than traditional treatments (the MIP mean difference overall effect was 10.8 and 2.3 KPa, respectively). In conclusion, MIP values can be considered as a reliable measure of swallowing function in adults and in children, with a more marked MIP difference between HC and patients for the children population. MIP measures in patients are also able to detect the best outcome on the tongue function after the training exercise compared to traditional training.

Beyond Laryngeal Clefts: Interarytenoid Injection Augmentation to Predict Success of Suture Augmentation in Children

OBJECTIVE

To assess the efficacy of interarytenoid injection augmentation (IAIA) and the ability of IAIA to predict response to interarytenoid suture augmentation (IASA) based on diet advancement on video fluoroscopic swallow studies (VFSS).

METHODS

Retrospective cohort analysis of patients with persistent pharyngeal dysphagia at a tertiary children's hospital with VFSS pre- and post-IAIA were included between March 2011 and June 2019.

RESULTS

Median age of the 229 patients was 2.2 years (5.8 months-19 years). Interarytenoid mucosal height (IAMH) was found to be above the false vocal folds in 112 patients (53.4%) and at true vocal folds in 10 (4.9%) patients. On VFSS post-IAIA, 95 (41.5%) patients were successfully advanced in recommended diet consistency, 115 (50.2%) were stable, and 19 (8.3%) needed thicker consistency. Paired t-tests on pre- and post-operative consistency scores showed significant improvement, p-value of <0.0001, 95% confidence interval (CI; 0.50-0.85). Poisson regression found no covariates with significant association with improvement on IAIA. For IASA patients, 35/60 (58.3%) improved on post-op VFSS. Paired t-tests on pre- and post-operative consistency scores showed significant improvement, p-value of <0.0001, 95% CI (0.63-1.33). Positive predictive value for IAIA predicting response to IASA was 77% with positive likelihood ratio of 2.3. The response to IAIA versus no response to IAIA likelihood ratios were found to have a statistically significant difference (p < 0.05).

CONCLUSIONS

Our study suggests IAIA yields objective improvement in swallow function on VFSS in nearly half of our patients and may be a reliable diagnostic tool to predict response to IASA in patients with persistent pharyngeal dysphagia with or without a laryngeal cleft.

Swallowing difficulties in adolescents: A case report and suggestion of treatment model

Dysphagia or difficulty swallowing in childhood necessitates multi-disciplinary evaluation and management. This case report highlights the teamwork required for diagnostic work-up to distinguish functional dysphagia from organic and psychiatric conditions in an adolescent girl. Treatment model based on cognitive behavioral therapy is also presented.

Relationship between Post-Stroke Cognitive Impairment and Severe Dysphagia: A Retrospective Cohort Study

Objective: To investigate the relationship between post-stroke cognitive impairment (PSCI) and severe post-stroke dysphagia (PSD) and explore the risk factors related to PSCI combined with severe PSD. Methods: Data from patients were collated from the rehabilitation-specific disease database. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Videofluoroscopy Swallowing Study (VFSS), Penetration-aspiration Scale (PAS), and Functional Oral Intake Scale (FOIS) were used to evaluate cognitive and swallowing functions. Differences between groups were determined by the Pearson chi-square test (χ2) or Fisher exact test. PAS and FOIS data were analyzed with the use of the Wilcoxon rank-sum or Kruskal−Wallis test in the prespecified subgroup analysis. Risk factors were investigated by multivariate logistic regression. Results: A total of 1555 patients were identified with PSCI. The results indicated that patients with PSCI had a higher incidence rate of severe PSD as compared to patients without PSCI (p < 0.001). Patients with severe PSCI were more likely to clinically manifest oral phase dysfunction (p = 0.024), while mild PSCI patients mainly manifested pharyngeal phase dysfunction (p < 0.001). There was a significant difference in FOIS score changes between subgroups during the hospitalization period (severe PSCI vs. moderate PSCI and severe PSCI vs. mild PSCI) (all p < 0.001). In addition, multivariate logistic regression revealed pneumonia (p < 0.001), tracheotomy (p < 0.001), and dysarthria (p = 0.006) were related to PSCI, combined with severe PSD. Conclusion: PSCI may be related to severe PSD. Patients with severe PSCI were more likely to manifest oral phase dysfunction, while mild PSCI manifested pharyngeal phase dysfunction. Pneumonia, tracheotomy, and dysarthria were risk factors related to PSCI combined with severe PSD.

Prevalence of dysphagia symptoms in Cretan children and adolescents with neurological disorders

Objectives

Dysphagia is defined as any feeding or swallowing dysfunction at one or more stages of digestion. This study aims to investigate the prevalence of dysphagia symptoms in children and adolescents with neurological disorders and its relationship with the specific characteristics of the subjects.

Methods

Using data from general hospital/paediatric department visits in Heraklion, Crete, Greece, a cross-sectional study design was implemented over a seven-month period (2017-18), and a total of 268 children and adolescents were recruited. Demographic data and medical profiles were recorded, focusing on the most obvious and frequent clinical features of feeding and swallowing disorders per stage (oral-OS, pharyngeal-PS, and oesophageal-ES).

Results

In the sample, 54.9% were boys and the mean age was 5.9 years; the most prevalent International Statistical Classification of Diseases and Related Health Problems (ICD-10) disorder was mental and behavioural disorders (37.3%). The prevalence of dysphagia symptoms was 24.3% during the OS (95% CI: 19.0-29.9), 18.3% in the PS (95% CI: 14.0-23.2), and 20.1% in the ES (95% CI: 15.7-25.4). At least one symptom of dysphagia was observed during the OS, PS, and ES in 42.5% (95% CI: 36.7-48.5) of the sample. The presence of dysphagia seems to be related to lower age (Odds Ratio [OR] = 0.45, p < 0.001), higher ICD-10 comorbidity (OR = 1.89, p < 0.05), or medication use (OR = 2.31, p < 0.05).

Conclusions

A high prevalence of dysphagia was found in children and adolescents with neurological disorders, while lower age, comorbidity, and medication use emerged as factors that required better management.

Pediatric Dysphagia

Feeding difficulty is common in the pediatric population, particularly in at-risk infants, such as those born prematurely. Appropriate work-up should involve a multidisciplinary team and may commonly use modified barium swallow and flexible endoscopic evaluation of swallow, in addition to history and physical examination. Structural causes of dysphagia may involve surgical management, whereas nonstructural causes may invoke medical therapies. If symptoms do not resolve following intervention, it is important to revisit the interdisciplinary team, because dysphagia is commonly multifactorial in origin. Appropriate identification and early intervention are necessary for successful outcomes in growth and development for children.

Neuromuscular electrical stimulation for children with dysphagia: a systematic review

OBJECTIVES

Dysphagia in childhood has important health impacts for the child and their family as well as the healthcare system. This systematic review aims to determine the effectiveness of neuromuscular electrical stimulation (NMES) for treatment of oropharyngeal dysphagia in children.

METHODS

A search was performed on November 2020 in MEDLINE (from 1946), EMBASE (from 1947), PsycINFO (from 1806), CINAHL (from 1937), CENTRAL (from 1996) and Scopus (from 1970) databases. Studies of children (≤18 years) diagnosed with oropharyngeal dysphagia using NMES in the throat/neck region were included. Screening, data extraction, and risk of bias assessment followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias was assessed using the Cochrane Collaboration's tool for randomised controlled trials (RCTs) and a modified Newcastle-Ottawa assessment for observational studies. A meta-analysis was not conducted due to clinical heterogeneity in studies.

RESULTS

Ten studies were included (5 RCTs, 4 case series, 1 cohort study; including 393 children, mean or median age below 7 years, including children with neurologic impairments). In all studies, swallowing function improved after NMES treatment. The standardised mean difference (SMD) for improvement of swallowing dysfunction in treatment compared with control groups in the RCTs ranged from 0.18 (95% CI -0.7 to 1.06) to 1.49 (95% CI 0.57 to 2.41). Eight of 10 studies reported on the child's feeding ability, and, with one exception, there was improvement in feeding ability. Few studies reported on health status (N=2), impact on caregiver (N=1), adverse events and harms (N=2), and child's quality of life (N=1). In most studies, outcome follow-up was less than 6 months. The studies demonstrated moderate to high risk of bias.

CONCLUSIONS

NMES treatment may be beneficial in improving swallowing function for children with dysphagia, however, given the quality of the studies, inadequate outcome reporting, and short follow-up duration, uncertainty remains. Well-designed RCTs are needed to establish its effectiveness before its adoption in clinical practice.

Validation and Cultural Adaptation of an Arabic Version of Pediatric Eating Assessment Tool (Pedi-EAT-10Arabic)

Pediatric eating assessment tool (Pedi-EAT-10_Arabic) is a validated and reliable caregiver administered outcome instrument designed for detection of children at high risk of penetration/aspiration. The objective of this study is to translate and validate the Arabic version of Pedi-EAT-10 and to correlate its results with pharyngeal residue and aspiration on fiber optic endoscopic examination of swallowing (FEES). A cross-sectional study including 202 children selected randomly from those attending the swallowing clinic in phoniatrics unit, Otorhinolaryngology department (ORL) at main university hospital between February 2019 and October 2020 complaining of dysphagia. For test-retest reliability, one hundred caregivers refilled the Pedi-EAT-10_Arabic after a 2-week period following their first visit. Validity was established by comparing the scores of dysphagia patients to healthy controls. Internal consistency of Pedi-EAT-10_Arabic was high (Cronbach's alpha 0.986). Intra class correlation showed excellent test-retest reliability (r = 0.968). The median Pedi-EAT 10_Arabic score was significantly higher in dysphagia group compared to healthy controls. (Median 27 IQR 21-34 for cases compared to median zero IQR 0-2 points for healthy controls, P less than 0.001). A strong correlation was found between Pedi-EAT 10_Arabic scores and PAS scores with Spearman's correlation coefficient r = 0.803 and P < 0.001. The ROC for evaluating the discriminatory capacity of Pedi-EAT 10 for aspiration showed an AUC of 0.92 (95% CI of 0.89 to 0.96)_. Conclusion: Pedi-EAT 10_Arabic was found to be a valid and reliable screening tool for further instrumental assessment of risk of dysphagia in pediatric population.

Optimal timing and technique for endoscopic management of dysphagia in pediatric aerodigestive patients

INTRODUCTION

The best strategy to manage an interarytenoid defect [Type 1 laryngeal cleft (LC-1) or deep interarytenoid groove (DIG)] in pediatric aerodigestive patients with dysphagia remains uncertain. This study compared benefit of interarytenoid augmentation (IAA) to suture repair or clinical observation alone in pediatric patients.

METHODS

A 3-year retrospective, single-center analysis of children with dysphagia undergoing endoscopic airway evaluation was performed. Physician preference guided treatment plan: suture repair with CO2 laser, IAA (carboxy methylcellulose or calcium hydroxyapatite), or observation. Primary outcome was improved post-operative diet. Significance was assumed at p < 0.05.

RESULTS

449 patients underwent diagnostic endoscopy. Mean age (±SD) at procedure was 21 ± 13 months, with nearly one fourth (28 %) of children ≤ 12 months. Eighty (18 %) had either an LC-1 (n = 55) or DIG (n = 25). Of these, 35 (42 %) underwent suture repair, 22 (28 %) IAA, and 23 (30 %) observation only. Aspiration improved overall in the interventional groups compared to observational controls (58 % vs. 9 %, p < 0.05), with no change in benefit observed by age of intervention. IAA was as effective as suture repair (59 % vs 55 %, p = 0.46). In patients with only a DIG, IAA intervention alone significantly improved swallow function (66.6 % vs. 0 %, p < 0.05).

CONCLUSION

In pediatric aerodigestive patients with dysphagia, 18 % of children have an addressable lesion. IAA or suture repair similarly improves dietary advancement. IAA improves swallow function in patients with DIG. These findings support a novel protocol to intervene in dysphagia patients with LC-1 or DIG via IAA at the initial operative evaluation.

Cricopharyngeal Achalasia Presenting as Acute Dysphagia in a Pediatric Patient

OBJECTIVE

To describe a case of idiopathic cricopharyngeal achalasia (CPA) in a pediatric patient with acute onset of dysphagia managed conservatively with supportive care.

METHODS

Sixteen-month-old boy presented with acute onset of gagging and coughing with feeding. His exam was notable for a well-appearing child with pooling of oral secretions and coarse breath sounds. Plain film series did not show radio-opaque foreign body (FB) and an esophagram demonstrated an endoluminal filling defect of the cervical esophagus and aspiration of contrast. He was taken to the operating room for urgent endoscopy but no FB or food impaction was observed. He had persistent symptoms that required further evaluation and a multidisciplinary team approach. Bedside laryngoscopy did not reveal any abnormalities. Modified barium swallow (MBS) study revealed upper esophageal sphincter (UES) dysfunction, consistent with cricopharyngeal achalasia. Repeat upper endoscopy with biopsies demonstrated mucosal irritation overlying the UES but histologic studies were negative for infectious causes.

RESULTS

He was treated with supportive care, including nasogastric feedings for nutrition supplementation as he was unable to tolerate oral feedings without aspiration. Over the course of 3 months after discharge, his symptoms resolved and repeat MBS was normal.

CONCLUSION

CPA is a rare cause of dysphagia in the pediatric population. Conservative management with supportive care is a reasonable approach in cases with acute onset in otherwise healthy children without underlying medical problems.

[Clinicopathological characterization of children with dysphagia, family impact and health-related quality of life of their caregivers]

INTRODUCTION

Oropharyngeal dysphagia (DOF) without proper evaluation can be underdiagnosed in certain groups of the pediatric population. Meeting the needs of these patients can lead to an overload of their caregivers.

OBJECTIVES

To describe the epidemiological and clinical characteristics of the patients evaluated after starting a monographic DOF clinic (C-DOF) and study whether there are changes at the nutritional level, as well as the burden and impact that caregivers find on quality of life related to health (HRQOL).

MATERIAL AND METHODS

Descriptive observational study of patients evaluated in a C-DOF from its start-up. To evaluate HRQOL, an ad hoc survey adapted from the Swallowing Quality of Life Questionnaire of the adult population was designed.

RESULTS

103 patients were evaluated, 85.4% presenting some neurological disease. A videofluoroscopic study was performed in 51 patients (49.5%), reporting combined alterations in both the oral and pharyngeal phases in 64.7% of them. There was a directly proportional correlation between the severity of the DOF and the presence of aspirations, as well as with the patient's motor impairment. Regarding the anthropometric evaluation, there was a trend toward improvement in weight z-score (+0.14 SD), height (+0.17 SD) and BMI (+0.16 SD). Out of 46.2% of the caregivers reported that the DOF problem interfered negatively in the basic activities of daily life. The increase in HRQOL, after the evaluation in the monographic DOF clinic, was statistically significant overall.

CONCLUSIONS

The monographic DOF clinic provided specialized care, impacting positively at the nutritional status of patients, as well as perceived changes in HRQOL, with a probable impact on caregivers.

Diagnosis and management of aspiration using fiberoptic endoscopic evaluation of swallowing in a Pediatric Pulmonology Unit

BACKGROUND AND OBJECTIVES

Swallowing disorders lead to chronic lung aspiration. Early detection and treatment of aspiration in children with dysphagia are important to prevent lung damage. Diagnosis of aspiration, which may be silent, requires an instrumental study such as fiberoptic endoscopic evaluation of swallowing (FEES). Despite its usefulness, it is rarely practiced by pediatric pulmonologists. This study aimed to evaluate the feasibility and utility of FEES performed in the pediatric respiratory unit of a tertiary hospital, analyze the clinical characteristics, endoscopic findings and proposed treatments, and identify the factors associated with penetration or aspiration.

METHODS

Medical records of 373 children with suspected aspiration who were referred to the pediatric respiratory unit for FEES were reviewed retrospectively. Clinical characteristics, FEES findings, and the proposed treatments were analyzed.

RESULTS

Laryngeal penetration/aspiration was seen in 47.9% of the patients. The most common associated conditions were neurological disease and prematurity. The most frequently observed endoscopic finding was altered laryngeal sensitivity (36.5%). Intervention was recommended in 54.2% of the patients. Complications were not seen during any of the procedures. The multivariate logistic regression model revealed an independent association between aspiration and alterations in laryngeal sensitivity (odds ratio [OR], 5.68), pharyngeal pooling (OR, 11.47), and post-swallowing food residues (OR, 8.08).

CONCLUSIONS

The FEES procedure performed by pediatric pulmonologists is a reliable method for diagnosing aspiration in children. It can be safely executed by trained pulmonologists, and significant endoscopic signs other than aspiration can guide in the diagnosis and management recommendations.

Thickened liquids: do they still have a place in the paediatric dysphagia toolkit?

PURPOSE OF REVIEW

Use of thickened fluids has long been a cornerstone of dysphagia management. However, clinicians and researchers are increasingly questioning their effectiveness and highlighting potential harms. This review aims to present the current state of the evidence for use of thickened fluids in children.

RECENT FINDINGS

The relationship between aspiration and respiratory infection is complex. The role of thickened fluids in improving respiratory health is limited and contradictory. A high level of variability exists in all aspects of thickened fluid use. Little is known about patient and family perspectives on meaningful endpoints for intervention.

SUMMARY

Clinicians should be open and transparent in their decision making with patients and families, acknowledging the limited evidence and the need for individualised care. Further research is needed to establish the efficacy of thickened fluid use in children with regard to improvements in respiratory health, fluid intake and child and family wellbeing.
