Pediatric tracheostomy speaking valves: A multidisciplinary protocol leads to earlier initial trials.

Early speaking valve application in children with tracheostomies is encouraged for language development. Whether an institutional multidisciplinary protocol impacts the patient population and timelines for which a speaking valve is trialed has not been studied. This retrospective study compared speaking valve trials performed at a pediatric quaternary hospital over a 12-year period. Timelines (time between tracheostomy insertion, speech-language pathologist (SLP) consultation, speaking valve order, and trial) and patient characteristics (demographics, tracheostomy classification, and feeding status) were collected. Medians (IQRs) compared timelines before and after a protocol was instituted and compared the timelines between tracheostomy classifications. Median time between tracheostomy insertion and SLP consultation did not change: before protocol-1.8 (7.7) months and after protocol-1.8 (2.4) months. Time between tracheostomy insertion and speaking valve trial decreased: before protocol-34.1 (40.5) months and after protocol-12.9 (8.4) months. Time between tracheostomy insertion and trial was not different between tracheostomy classifications: upper airway obstruction-16.0 (27.1) months, complex medical condition-36.3 (45.8) months, and invasive ventilation-17.5 (22.3) months. An institutional multidisciplinary protocol decreases the time between tracheostomy insertion and speaking valve trial, regardless of the reason the tracheostomy is needed in the pediatric population.

Treatment of dysphasia with rTMS and language therapy after childhood stroke: Multimodal imaging of plastic change.

Expressive dysphasia accompanies left inferior frontal gyrus (IFG/Broca) injury. Recovery may relate to interhemispheric balance with homologous, contralesional IFG but is unexplored in children. We evaluated effects of inhibitory rTMS to contralesional IFG combined with intensive speech therapy (SLT). A 15year-old, right-handed male incurred a left middle cerebral artery stroke. After 30months, severe non-fluent dysphasia impacted quality of life. Language networks, neuronal metabolism and white matter pathways were explored using MRI. Language function was measured longitudinally. An intensive SLT program was combined with contralesional inhibitory rTMS of right pars triangularis. Procedures were well tolerated. Language function improved persisting to four months. Post-treatment fMRI demonstrated increased left perilesional IFG activations and connectivity at rest. Bilateral changes in inositol and glutamate metabolism were observed. Contralesional, inhibitory rTMS appears safe in childhood stroke-induced dysphasia. We observed clinically significant improvements after SLT coupled with rTMS. Advanced neuroimaging can evaluate intervention-induced plasticity.
