Hyperacusis in Children: A Preliminary Study on the Effects of Hypersensitivity to Sound on Speech and Language.

There is a growing awareness that children may experience hyperacusis, a condition that is often associated with behavioral and developmental disorders. This preliminary study was aimed to investigate the effects of hyperacusis alone on various components of speech and language in children without developmental disorders. This study was conducted on 109 children aged between 4 and 7 years attending kindergarten and primary school. Hyperacusis was assessed through behavioral observation of children and questionnaires for parents. Different components of speech and language were assessed through specific tests. Hyperacusis was diagnosed in fifteen children (13.8%); ten (66.7%) were attending primary school and five (33.3%) kindergarten. A significant difference between children with and without hyperacusis was found for tests evaluating the average number of words in a sentence and phonemic fluency; older children appeared to have more difficulties. Several differences in education profiles were found: parents of children with hyperacusis spent less time with their children compared to parents of children without hyperacusis. Our preliminary results suggest some difficulties in lexical access and the use of shorter sentences by children with hypersensitivity to sound; however, the small size of our sample and the largely unknown interactions between hyperacusis and developmental disorders suggest caution when interpreting these results. Further studies on larger samples are necessary to gain additional knowledge on the effects of hyperacusis on speech and language in children without developmental disorders.

Tinnitus Holistic Simplified Classification (THoSC): A New Assessment for Subjective Tinnitus, With Diagnostic and Therapeutic Implications.

OBJECTIVE: One of the most debated topics in tinnitus is its standard and practical classification. The most popular classification distinguishes subjective from objective tinnitus. Other classifications are based on different features. On the whole, they seem incomplete, and the diagnostic and therapeutic algorithms are often difficult for practical purposes. The aim of this work is to develop a new diagnostic and therapeutic algorithm. METHODS: Our model is based on 10 years of experience. In particular, the starting point is the data retrieved from 212 consecutive patients in our Tinnitus Unit between May and December 2013: We found a clear auditory disorder in 74.5% of the population, muscolo-skeletal disorders and/or trigeminal disease in 57.1%, and psychiatric comorbidities in 43.8%. Different features coexisted in 59.9% of the population. RESULTS: Following such data we propose the Tinnitus Holistic Simplified Classification, which takes into account the different tinnitogenic mechanisms and the interactions between them. It differentiates tinnitus that arises from: (1) auditory alterations (Auditory Tinnitus), (2) complex auditory-somatosensory interactions (Somatosensory Tinnitus), (3) psychopathological-auditory interactions (Psychopathology-related Tinnitus), and (4) 2 or all of the previous mechanisms (Combined Tinnitus). CONCLUSIONS: In our opinion this classification provides an accurate and easy tailored path to manage tinnitus patients.
