RESUMEN
OBJECTIVE: Children with single-sided deafness often receive inconsistent clinical recommendations because there is currently no clear best practice in paediatric single-sided deafness. This systematic review of the literature aimed to compare commonly used treatments and attempted to support the use of a particular treatment modality. METHOD: This was a comprehensive literature review from 1 January 2000 to 22 February 2022; the study compared the outcomes of bone conduction devices and cochlear implantation in paediatric patients with single-sided deafness. RESULTS: Fifteen studies consisting of 202 patients were examined. Variables including speech reception in quiet and noise, as well as quality of life measures were compared. Both cochlear implantation and bone-anchored hearing aids demonstrated benefits in sound perception. Quality of life measures improved with both modalities. CONCLUSION: Although both bone-anchored hearing aids and cochlear implantation appear to provide significant improvements, additional research with more direct comparisons is needed to provide more decisive results.

Primary production in coastal wetlands is conventionally thought to be limited by nitrogen. Although the plant community in a pristine salt marsh was found to be limited primarily by nitrogen availability, the bacterial community in the soil was limited by phosphorus. Hence, in coastal wetlands, and possibly in many ecosystems, individual trophic groups may respond differently to nitrogen and phosphorus loading. Phosphorus limitation of the growth of nitrogen-transforming bacteria will affect carbon fixation, storage, and release mediated by plants, a result that has important implications for ecosystem management.
