Objective: To determine associations between presenting symptoms and oropharyngeal dysphagia diagnoses, gastroesophageal reflux disease (GERD) diagnoses, and treatment with acid suppression medication in infants with brief resolved unexplained event (BRUE)., Study Design: We performed a prospective cohort study of infants with BRUE to review presenting symptoms and their potential impact on testing and treatment. Videofluoroscopic swallow study (VFSS) results and explanatory diagnoses were obtained from medical record review; acid suppression use was determined by parental survey. Binary and multivariable logistic regression models were used to evaluate associations between presenting symptoms and obtaining VFSS, VFSS results, GERD diagnoses, and acid suppression medication., Results: Presenting symptoms were varied in 157 subjects enrolled at 51.0 ± 5.3 days of age, with many symptoms that may be related to GERD or dysphagia. Of these, 28% underwent VFSS with 71% abnormal. Overall, 42% had their BRUE attributed to GERD, and 33% were treated with acid suppression during follow-up. Presenting symptoms were significantly associated with the decision to obtain VFSS but not with abnormal VFSS results. Presenting symptoms were also associated with provision of GERD explanatory diagnoses. Both presenting symptoms and GERD explanatory diagnoses were associated with acid suppression use (aOR 2.3, 95% CI 1.03-5.3, P = .04)., Conclusions: Presenting symptoms may play a role in clinicians' decisions on which BRUE patients undergo VFSS but are unreliable to make a diagnosis of oropharyngeal dysphagia. Presenting symptoms may also influence assignment of GERD explanatory diagnoses that is associated with increased acid suppression medication use., Competing Interests: Declaration of Competing Interest This work was supported by NIH K23 DK127251 (DRD) and NIH R01 DK097112 (RLR).The authors declare no conflicts of interest.

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., Competing Interests: Declaration of Competing Interest This work was previously presented in part at Digestive Diseases Week, May 21-24, 2022, San Diego, California.

Objective: To determine whether the use of acid suppression and thickened feeds impact laryngomalacia outcomes in infants, including supraglottoplasty risk, time to supraglottoplasty, and hospitalization risk., Study Design: We performed a retrospective cohort study to compare risk and time with supraglottoplasty and frequency and duration of hospitalizations for infants diagnosed with laryngomalacia at Boston Children's Hospital between January 1 and December 31, 2017. The primary outcomes were supraglottoplasty requirement, time to supraglottoplasty, and hospitalization risk. Multivariate analyses were performed to determine predictors of supraglottoplasty and hospitalization risk after adjusting for laryngomalacia severity and comorbidities in addition to propensity score adjustment. Kaplan-Meier curves were created to determine the impact of acid suppression use on time to supraglottoplasty., Results: In total, 236 subjects with mean age 62.6 ± 4 days were included in the analysis; 55% were treated with acid suppression. Subjects treated with acid suppression had a greater risk of supraglottoplasty (hazard ratio 3.36, 95% CI 1.36-8.29, P = .009), shorter time to supraglottoplasty (5.64 ± 0.92 vs 7.98 ± 1.92 months, P = .006), and increased respiratory hospitalization risk (relative risk 1.97, 95% CI 1.01-3.85, 0.047), even after adjustment for covariates. Subjects receiving thickening had fewer respiratory hospitalization nights and longer time to supraglottoplasty (9.3 ± 1.7 vs 4.56 ± 0.73 months, P = .004), even after adjustment., Conclusions: Acid suppression use does not reduce the frequency of supraglottoplasty and related hospitalizations compared with untreated subjects. However, patients treated with thickening have decreased hospitalization and longer time to supraglottoplasty, suggesting that thickening of feeds may be a preferred intervention over acid suppression., (Copyright © 2021.

Objectives: To determine if hospitalization, testing, diagnosis, and management of suspected gastroesophageal reflux, and follow-up visits decreased since introduction of American Academy of Pediatrics guidelines for brief resolved unexplained events (BRUEs)., Study Design: We performed a retrospective cohort study of infants with BRUE evaluated at Boston Children's Hospital in the year before and after guideline implementation to determine if practice patterns have changed. Outcomes included hospitalization rates, frequency of swallow assessments, other diagnostic testing, and reflux diagnoses, cost of care, and number of repeat visits. Groups were compared based on whether they presented before or after guideline implementation., Results: In total, 359 subjects (186 pre-, 173 post-guidelines) were identified. There were no significant differences in practice patterns or outcomes before or after guideline implementation. Subjects had mean age 2.53 ± 0.15 months, and 80% were hospitalized for 2.49 ± 0.26 days. Each subject had 2.47 diagnostic tests performed, and 89% were noncontributory. Despite only 13% having videofluoroscopic swallow study performed, 72% showed aspiration/penetration. No subject had gastroesophageal reflux testing, yet reflux was implicated as the cause for admission in 40% of subjects, resulting in increased odds of discharge on acid suppressing medications (OR 2.88, 95% CI 1.68-4.92, P = .0001). In follow-up, 28% of subjects had repeat hospitalizations or emergency department visits for persistent symptoms., Conclusions: Infants with BRUE continue to undergo low-yield diagnostic testing and after admission remain symptomatic and frequently re-present to medical care. Swallow testing remains infrequent despite its high-yield, reflux continues to be implicated and children are still being discharged on acid suppression despite lack of efficacy., (Copyright © 2019 Elsevier Inc.

Objectives: To determine if any presenting symptoms are associated with aspiration risk, and to evaluate the reliability of clinical feeding evaluation (CFE) in diagnosing aspiration compared with videofluoroscopic swallow study (VFSS)., Study Design: We retrospectively reviewed records of children under 2 years of age who had evaluation for oropharyngeal dysphagia by CFE and VFSS at Boston Children's Hospital and compared presenting symptoms, symptom timing, and CFE and VFSS results. We investigated the relationship between symptom presence and aspiration using the Fisher exact test and stepwise logistic regression with adjustment for comorbidities. CFE and VFSS results were compared using the McNemar test. Intervals from CFE to VFSS were compared using the Student t test., Results: A total of 412 subjects with mean (±SD) age 8.9 ± 6.9 months were evaluated. No symptom, including timing relative to meals, predicted aspiration on VFSS. This lack of association between symptoms and VFSS results persisted even in the adjusted multivariate model. The sensitivity of CFE for predicting aspiration by VFSS was 44%. Patients with a reassuring CFE waited 28.2 ± 8.5 days longer for confirmatory VFSS compared with those with a concerning CFE (P < .05)., Conclusions: Presenting symptoms are varied in patients with aspiration and cannot be relied upon to determine which patients have aspiration on VFSS. The CFE does not have the sensitivity to consistently diagnose aspiration so a VFSS should be performed in persistently symptomatic patients., (Copyright © 2018 Elsevier Inc. All rights reserved.)
