The post-traumatic origin of benign paroxysmal positional vertigo remains the most likely, from a patho-physiologic point of view. Benign paroxysmal positional vertigo due to surgical "traumas" has been described in the medical literature. According to personal experience, these iatrogenic cases represent a rare possibility and may be the consequence of(More)
Mutations in the gene (GJB2) coding for Connexin 26 (Cx26) are responsible for genetic forms of sensorineural hearing loss. This article describes a family characterized by congenital profound hearing loss, inherited in an autosomal dominant fashion and associated to a R75Q substitution in Cx26. Cell transfection and fluorescence imaging, dye transfer(More)
OBJECTIVE To investigate the protective effect of two anti-reactive oxygen species (ROS) substances, copper-zinc superoxide dismutase (CuZn-SOD) and allopurinol, in impulse noise-exposed guinea pigs. MATERIAL AND METHODS Allopurinol or CuZn-SOD were administered intraperitoneally before exposure to 125 dB SPL noise centered at 2.0-3.0 kHz, with a(More)
We have investigated brainstem and cortical auditory responses (BAERs and CAERs) in 16 cases of Friedreich's ataxia (FA) and have compared the findings with those obtained in 2 cases of familial spastic paraplegia (FSP), in 5 cases of Charcot-Marie-Tooth disease (CMTD), and in 6 cases of atypical FA of uncertain classification. BAERs could not be elicited(More)
Our understanding of the genetic basis of Ménière's disease (MD) is still limited. Although the familial clustering and the geographical and racial differences in incidence strongly suggest a certain role for genetic factors in the development of MD, no convincing evidence for an association with any gene exists, at present. In this review, starting from(More)
In selecting patients to undergo cochlear implant, a pre-existing use of sign language gives rise to two problems that have been widely debated in the literature. First, the caution shown toward the candidacy of patients using this mode of communication, since it is considered a possible element of interference in the acquisition of speech. Secondly,(More)
We investigated the relationship between dental and maxillofacial surgery and benign paroxysmal positional vertigo (BPPV). BPPV represents the most frequent cause of vertigo of labyrinthine origin. BPPV has been reported following surgical trauma from various surgical interventions, regarding anatomical site and technical execution. A surgical origin is, in(More)
The aim of this systematic review was to summarize the results of scientific publications on the clinical effectiveness of the cochlear implant (CI) procedure in adults. The members of the Working Group first examined existing research evidence from the national and international literature and main international guidelines. They considered as universally(More)
