Int Arch Otorhinolaryngol 2019 Jan 11;23(1):12-17. Epub 2018 Oct 11.

Secretaria de Saúde do Distrito Federal, Brasília, DF, Brazil.

 The bone-anchored hearing aid (BAHA) is a bone conduction system that transmits the sound directly to the inner ear by surpassing the skin impedance and the subcutaneous tissue. It is indicated for patients with mixed, conductive and unilateral sensorineural hearing loss who did not benefit from conventional hearing aids (HAs). Although the benefits from BAHA are well demonstrated internationally, this field still lacks studies in Brazil. Read More

Comparison of the Reynell Developmental Language Scale II and the Galker test of word-recognition-in-noise in Danish day-care children.

Int J Pediatr Otorhinolaryngol 2018 Jun 3;109:104-111. Epub 2018 Apr 3.

Research Unit for General Practice in Copenhagen, University of Copenhagen, Denmark.

Objective: To search for predictive factors for language development measured by two receptive language tests for children, the Galker test (a word-recognition-in-noise test) testing hearing and vocabulary, and the Danish version of Reynell Developmental Language Scale (2nd revision, RDLS II) test, a language comprehension test. The study analysed if information about background variables and parents and pre-school teachers was predictive for test scores; if earlier middle ear disease, actual hearing loss and tympanometry was important for language development; and if the two receptive tests differed in terms of the degree to which variables were able to predict test scores at the age of three to five years.

Methods: All children aged three and five years attending 20 day-care centres for children without cognitive development issues from the Municipality of Hillerød, Denmark, were invited to participate. Read More

Auditory function in Pelizaeus-Merzbacher disease.

J Neurol 2018 Jul 3;265(7):1580-1589. Epub 2018 May 3.

Nemours Biomedical Research, Center for Applied Clinical Genomics, Nemours/Alfred I. duPont Hospital for Children, Wilmington, DE, USA.

Pelizaeus-Merzbacher disease (PMD; MIM 312080), an inherited defect of central nervous system myelin formation, affects individuals in many ways, including their hearing and language abilities. The aim of this study was to assess the auditory abilities in 18 patients with PMD by examining the functional processes along the central auditory pathways using auditory brainstem responses (ABR) and cortical auditory evoked potentials (CAEP) in response to speech sounds. The significant ABR anomalies confirm the existence of dyssynchrony previously described at the level of the brainstem in patients with PMD. Read More

Dynamic Slow Motion Video Endoscopy as an Adjunct to Impedance Audiometry in the Assessment of Eustachian Tube Function.

Int Arch Otorhinolaryngol 2018 Apr 16;22(2):141-145. Epub 2017 Jun 16.

Department of ENT, Jawaharlal Institute of Post Graduate Medical Education, Puducherry, India.

 Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment.  To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases.

Royal Brompton and Harefield NHS Trust, Sydney Street, London, SW3 6NP, UK.

Introduction: Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term.
