CHL has also been implicated in the development of speech and language acquisition (Reichman and Healey, 1983;Bennett and Furukawa, 1984;Schlieper et al, 1985;Teele et al, 1990;Schonweiler et al, 1998;Mody et al, 1999;Psillas et al, 2006). Despite this, little is known about the consequences of CHL on central auditory function.…”

Although sensorineural hearing loss (SNHL) is known to compromise central auditory structure and function, the impact of milder forms of hearing loss on cellular neurophysiology remains mostly undefined. We induced conductive hearing loss (CHL) in developing gerbils, reared the animals for 8 -13 d, and subsequently assessed the temporal features of auditory cortex layer 2/3 pyramidal neurons in a thalamocortical brain slice preparation with whole-cell recordings. Repetitive stimulation of the ventral medial geniculate nucleus (MGv) evoked robust short-term depression of the postsynaptic potentials in control neurons, and this depression increased monotonically at higher stimulation frequencies. In contrast, CHL neurons displayed a faster rate of synaptic depression and a smaller asymptotic amplitude. Moreover, the latency of MGv evoked potentials was consistently longer in CHL neurons for all stimulus rates. A separate assessment of spike frequency adaptation in response to trains of injected current pulses revealed that CHL neurons displayed less adaptation compared with controls, although there was an increase in temporal jitter. For each of these properties, nearly identical findings were observed for SNHL neurons. Together, these data show that CHL significantly alters the temporal properties of auditory cortex synapses and spikes, and this may contribute to processing deficits that attend mild to moderate hearing loss.

Is Health Care Support Associated with Better Educational Achievement in Sensorineural Hearing Impaired Students with Overlooked Recurrent Otitis Media?

Background: Otitis media is an important health care problem in school-age children. Moreover, the prevalence of allergic rhinitis, a major and common cause of otitis media, is increasing among children. Recurrent otitis media may occur without any noticeable symptoms and affect the auditory threshold (AT). Only a few decibles increase in hearing loss does not have the same effect on the hearing ability of individuals with different degrees of hearing loss. With this background in mind, in this study, we aimed to determine whether diagnosis and medical treatment of overlooked recurrent otitis media are associated with the educational achievement of students with sensorineural hearing impairment. Methods: The present study with a pretest-posttest design was conducted on 30 students (aged 12 -20 years) with bilateral sensorineural hearing impairment, AT above 30 dB HL in the better ear, and recurrent (2 episodes) middle ear infection over 9 months during 2012 -2014. The participants were examined regularly and received medical treatment when indicated. The mean scores of total average, Persian literature (eg, reading, writing, and spelling), and mathematics were measured to assess the subjects' educational achievement. Results: Based on the findings, the total average scores significantly changed from 16.2 to 17.2. Also, the students' Persian literature (from 16.8 to 18) and mathematics (from 13.8 to 16.7) scores were significantly improved. In addition, AT considerably decreased after

“…She had evidence of long standing secretory otitis media in the right ear, but there were only minor changes in the left. After surgery she progressed well with intensive speech therapy in a language unit, but at age 5 years 11 months, her Reynell language development scale scores were lower than those normal for her age (comprehension 4-02, expression 4-08, English picture vocabulary scale [2][3][4][5][6][7][8][9][10][11] The history suggested that in this case the secretory otitis media was associated with the respiratory infection, and the episode was of such brief duration that there was no noticeable effect on language development.…”

SUMMARY Secretory otitis media is a very common disorder in early childhood, but its effects on language development are still uncertain. We describe 10 children with secretory otitis media and illustrate the wide range of disability attributable to this. It There has been much concern over the possible effects of middle ear disease on learning in general and language development in particular. This relation has been examined in over 30 published reports, and in most, significant correlations have been shown.6 The majority of these studies, however, contain serious flaws in design. Most are retrospective, and therefore the precise diagnosis is often uncertain in the children with a history of ear disease; conversely the absence of previous ear disease in the control group cannot be shown. For the same reason, the number and duration of attacks, the severity of the hearing loss, and the distinction between unilateral and bilateral disease are seldom documented. Lastly, matching of cases and controls for psychosocial variables is seldom adequate, yet accurate matching is essential since the prevalence and perhaps the management of secretory otitis media are related to race, size of household, and social status, and these variables also influence development. It must therefore be said that the case for a cause and effect relation between secretory otitis media and learning problems remains unproved.7Despite shortcomings of published research, most clinicians with an interest in this field are convinced that secretory otitis media is indeed an important cause of developmental problems in young children. The purpose of this paper is to present some illustrative case histories; to derive from these a working hypothesis on the nature of the relation between secretory otitis media and developmental problems; and to discuss the type of research design needed to investigate this hypothesis. Methods and case reportsThe children described here were seen in two children's audiology clinics over a three year period.
