Difficulty swallowing or dysphagia can be present in children and adults alike. Pediatric dysphagias have long been recognized in the literature. Certain groups of infants with specific developmental and/or medical conditions have been identified as being at high risk for developing dysphagia. Still others may present with a swallowing or feeding problem as their primary symptom. Left untreated, these problems in infants and children can lead to failure to thrive, aspiration pneumonias, gastroesophageal reflux, and/or the inability to establish and maintain proper nutrition and hydration. Awareness of the prevalence of pediatric dysphagia in today's population and the signs and symptoms of this condition aids in its treatment. Early detection of dysphagia in infants and children is important to prevent or minimize complications. This article provides a review of symptoms, etiologies, and resources available regarding management of this condition to help the primary care physician and the families of young children and infants in its management.

    • "In animals which use a common oropharyngolaryngeal passage for breathing and swallowing, the coordination of each activity is of vital importance to sustaining life and airway protection. Proper synchronization of functionally shared passages is reliant upon common neurological pathways originating from brainstem nuclei (Bolser et al., 2006), with loss of regulation potentially leading to a range of negative sequelae including aspiration, malnutrition, and dehydration (Prasse and Kikano, 2009; Shaker et al., 1992).

    ABSTRACT: Herein we compare the effects of perturbations in the Kölliker-Fuse nucleus (KFN) and the lateral (LPBN) and medial (MPBN) parabrachial nuclei on the coordination of breathing and swallowing. Cannula were chronically implanted in goats through which ibotenic acid (IA) was injected while awake. Swallows in late expiration (E) always reset while swallows in early inspiration (I) never reset the respiratory rhythm. Before cannula implantation, all other E and I swallows did not reset the respiratory rhythm, and had small effects on E and I duration and tidal volume (VT). However, after cannula implantation in the MPBN and KFN, E and I swallows reset the respiratory rhythm and increased the effects on I and E duration and VT. Subsequent injection of IA into the KFN eliminated the respiratory phase resetting of swallows but exacerbated the effects on I and E duration and VT. We conclude that the KFN and to a lesser extent the MPBN contribute to coordination of breathing and swallowing.

    • "Immediate appropriate intervention is required for infant dysphagia, because it can cause not only respiratory organ complications such as aspiration pneumonia, but also malnutrition and developmental delays [3,17,18]. Feeding interventions in infants involve position changes, flow rate adjustment, texture modification, oral stimulation, desensitization, nutritional interventions and alternative feeding [18,19]. Accurate identification of the pathophysiology of swallowing abnormalities via VFSS is helpful for determining appropriate feeding interventions [20]. "

    ABSTRACT: To determine the clinical characteristics and videofluoroscopic swallowing study (VFSS) findings in infants with suspected dysphagia and compare the clinical characteristics and VFSS findings between full-term and preterm infants. A total of 107 infants (67 full-term and 40 preterm) with suspected dysphagia who were referred for VFSS at a tertiary university hospital were enrolled in this retrospective study. Clinical characteristics and VFSS findings were reviewed by a physiatrist and an experienced speech-language pathologist. The association between the reasons of referral for VFSS and VFSS findings were analyzed. Mean gestational age was 35.1±5.3 weeks, and mean birth weight was 2,381±1,026 g. The most common reason for VFSS referral was 'poor sucking' in full-term infants and 'desaturation' in preterm infants. The most common associated medical condition was 'congenital heart disease' in full-term infants and 'bronchopulmonary dysplasia' in preterm infants. Aspiration was observed in 42 infants (39.3%) and coughing was the only clinical predictor of aspiration in VFSS. However, 34 of 42 infants (81.0%) who showed aspiration exhibited silent aspiration during VFSS. There were no significant differences in the VFSS findings between the full-term and preterm infants except for 'decreased sustained sucking.' There are some differences in the clinical manifestations and VFSS findings between full-term and preterm infants with suspected dysphagia. The present findings provide a better understanding of these differences and can help clarify the different pathophysiologic mechanisms of dysphagia in infants.

    • "Dysphagia can also induce feeding-related stress and challenges, affecting the psychosocial well-being of the child, family and other caregivers [2]. A particularly dangerous condition, aspiration pneumonia, is frequently associated with dysphagia [5]. Silent aspiration, that is, the entry of foodstuffs into the airway in the absence of a cough or other overt response, is generally difficult to detect during routine clinical swallowing assessments without videofluoroscopy.

    ABSTRACT: Dysphagia or swallowing disorder negatively impacts a child's health and development. The gold standard of dysphagia detection is videofluoroscopy which exposes the child to ionizing radiation, and requires specialized clinical expertise and expensive institutionally-based equipment, precluding day-to-day and repeated assessment of fluctuating swallowing function. Swallowing accelerometry is the non-invasive measurement of cervical vibrations during swallowing and may provide a portable and cost-effective bedside alternative. In particular, dual-axis swallowing accelerometry has demonstrated screening potential in older persons with neurogenic dysphagia, but the technique has not been evaluated in the pediatric population. In this study, dual-axis accelerometric signals were collected simultaneous to videofluoroscopic records from 29 pediatric participants (age 6.8 ± 4.8 years; 20 males) previously diagnosed with neurogenic dysphagia. Participants swallowed 3-5 sips of barium-coated boluses of different consistencies (normally, from thick puree to thin liquid) by spoon or bottle. Videofluoroscopic records were reviewed retrospectively by a clinical expert to extract swallow timings and ratings. The dual-axis acceleration signals corresponding to each identified swallow were pre-processed, segmented and trimmed prior to feature extraction from time, frequency, time-frequency and information theoretic domains. Feature space dimensionality was reduced via principal components. Using 8-fold cross-validation, 16-17 dimensions and a support vector machine classifier with an RBF kernel, an adjusted accuracy of 89.6% ± 0.9 was achieved for the discrimination between swallows with and with out airway entry. Our results suggest that dual-axis accelerometry has merit in the non-invasive detection of unsafe swallows in children and deserves further consideration as a pediatric medical device.
