The Effectiveness of Slightly Thick Liquids for Improving Swallowing in Bottle-Fed Children With Aerodigestive Concerns.

Purpose: Strategies for facilitating safe and functional bottle feeding in children with dysphagia include selecting nipples that reduce flow rate, pacing, altered positioning, and thickening liquid consistencies. We aimed to determine the impact of slightly thick liquids on swallowing through retrospective review of a convenience sample of clinical videofluoroscopic swallowing studies (VFSS) from 60 bottle-fed children (21 boys and 39 girls, mean age of 9.9 months) referred due to suspected aspiration. Method: Eligible VFSS exams were those in which the child swallowed both thin and slightly thick barium (40% w/v Varibar barium) using the same nipple. VFSS sequences (i.e., uninterrupted portions of the VFSS recording) were randomly assigned in duplicate for rating by trained raters; discrepancies were resolved by consensus. Parameters measured included number of swallows/sequence, sucks/swallow, swallow and sequence duration, number and timing of penetration or aspiration events, laryngeal vestibule closure integrity, and pharyngeal residue. Chi-square tests, linear mixed-model analyses of variance, and Wilcoxon signed-ranks tests identified consistency effects. Results: There were no aspiration events in these recordings. Slightly thick liquids resulted in significantly fewer penetration events (p < .05), increased sucks/swallow, fewer swallows/sequence, and longer swallow and sequence durations. The number of children with ≥ 1 sequence showing pyriform sinus residue was significantly higher with slightly thick liquids. Conclusions: Slightly thick liquids can be effective in reducing penetration in bottle-fed children with dysphagia. However, slightly thick liquids may also lead to a safety-efficiency trade-off, with increased risk of pyriform sinus residue. Thickening for children with dysphagia should be considered only when other approaches are not effective. Overthickening should be avoided to limit negative impact on swallowing efficiency.

Factors associated with frenotomy after a multidisciplinary assessment of infants with breastfeeding difficulties.

OBJECTIVE: Frenotomy for ankyloglossia has increased nearly 10-fold over the past few decades despite insufficient evidence that the procedure improves breastfeeding outcomes. There is no universally accepted method for identifying patients who may benefit from the procedure. The objective of this study is to determine if comprehensive feeding evaluations and targeted interventions can identify children who should undergo procedures, and to identify factors associated with lip or tongue frenotomy to treat breastfeeding difficulties. METHODS: This observational quality improvement study followed infant-mother dyads between March 2018 and December 2019 referred to our tertiary care center for breastfeeding difficulties. Speech and language pathologists performed comprehensive feeding evaluations on infants prior to surgical consultation for frenotomy. Infants' oral anatomy and function and their ability to breast and bottle feed were assessed, and techniques for mothers to address feeding difficulties without a procedure were offered prior to surgical consultation. Infants either found success over a short observation period or underwent procedures (lip and/or tongue frenotomy). RESULTS: 153 patients (mean age 47.0 days (stdev 39.0 days, 56.2% male) were referred for surgical division of the lingual frenulum. Following development of a program utilizing pediatric speech language pathologists to perform feeding evaluations prior to surgical consultation, 69.9% of patients subsequently did not undergo surgical procedures. 11 (23.9%) underwent labial frenotomy alone and 30 (65.2%) underwent both labial and lingual frenotomies. Frenotomy was associated with significantly increased worry subscale of the Feeding Swallow Impact Survey (FSIS) and decreased mean Breastfeeding Self Efficacy Scale score (p = 0.0001, p = 0.006, respectively). Tongue appearance was significantly associated with having a procedure, while lip appearance was not. The Bristol Breastfeeding Assessment Tool (BBAT) was lower in children undergoing tongue and/or lip frenotomy (p = 0.0006), while the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) appearance and function scores were lower in children undergoing lingual frenotomy with or without lip frenotomy (p = 0.0008, p = 0.0009, respectively). CONCLUSIONS: The majority of patients referred for ankyloglossia may benefit from nonsurgical intervention strategies based on findings from comprehensive feeding evaluation. Frenotomy is associated with higher maternal feeding-related worry and reduced breastfeeding self-efficacy scores. While tongue appearance is associated with frenotomy, functional assessment is critical for identifying patients who may also benefit from lip frenotomy.

Association of Feeding Evaluation With Frenotomy Rates in Infants With Breastfeeding Difficulties.

IMPORTANCE: Inpatient surgical release of lingual frenulums rose 10-fold between 1997 and 2012 despite insufficient evidence that frenotomy for ankyloglossia is associated with improvements in breastfeeding. Clear indications for surgical release remain murky, and best practice guidelines have yet to be developed. OBJECTIVE: To determine whether infants referred for frenotomy to treat breastfeeding difficulties should undergo procedures after comprehensive feeding examination, during which the primary cause of feeding issues was identified, and targeted intervention was provided. DESIGN, SETTING, AND PARTICIPANTS: This observational quality improvement study followed mother-infant dyads between March and December of 2018 who were referred to our tertiary care center for difficulty with breastfeeding. All infants underwent a comprehensive feeding evaluation by speech and language pathologists who examined the infants' ability to breastfeed prior to a surgical consultation for initial frenotomy. Data analysis was performed between January 2019 and May 2019. INTERVENTIONS: A multidisciplinary feeding evaluation that examined infants' oral structure and function and their ability to breastfeed and that offered techniques for mothers to address any feeding difficulties prior to surgical intervention was developed. Infants either found success in feeding and weight gain through this program or underwent procedures. MAIN OUTCOMES AND MEASURES: The primary outcome was the percentage of frenotomy procedures following implementation of a multidisciplinary feeding team evaluation. The secondary outcome was the percentage of infants referred for lingual frenotomy who later had either combined lingual and labial frenotomy or labial frenotomy alone. RESULTS: Included in the study were 115 patients (median age, 34 days [interquartile range, 19-56 days], 68 (59%) were male) referred for surgical division of the lingual frenum. Following the development of a program with feeding examination with a pediatric speech and language pathologist, 72 (62.6%) patients subsequently did not undergo surgical procedures. Although all of the referrals were for lingual frenotomy, 10 (8.7%) underwent labial frenotomy alone and 32 (27.8%) underwent both labial and lingual frenotomy. CONCLUSIONS AND RELEVANCE: The majority of patients referred for ankyloglossia may benefit from alternative intervention strategies following comprehensive feeding evaluation. Close collaboration and formation of multidisciplinary teams are imperative for treating these children.

Auditory-motor mapping training as an intervention to facilitate speech output in non-verbal children with autism: a proof of concept study.

Although up to 25% of children with autism are non-verbal, there are very few interventions that can reliably produce significant improvements in speech output. Recently, a novel intervention called Auditory-Motor Mapping Training (AMMT) has been developed, which aims to promote speech production directly by training the association between sounds and articulatory actions using intonation and bimanual motor activities. AMMT capitalizes on the inherent musical strengths of children with autism, and offers activities that they intrinsically enjoy. It also engages and potentially stimulates a network of brain regions that may be dysfunctional in autism. Here, we report an initial efficacy study to provide 'proof of concept' for AMMT. Six non-verbal children with autism participated. Prior to treatment, the children had no intelligible words. They each received 40 individual sessions of AMMT 5 times per week, over an 8-week period. Probe assessments were conducted periodically during baseline, therapy, and follow-up sessions. After therapy, all children showed significant improvements in their ability to articulate words and phrases, with generalization to items that were not practiced during therapy sessions. Because these children had no or minimal vocal output prior to treatment, the acquisition of speech sounds and word approximations through AMMT represents a critical step in expressive language development in children with autism.
