A growing interest in cognitive effects associated with speech and hearing processes is spreading throughout the scientific community essentially guided by evidence that central and peripheral hearing loss is associated with cognitive decline. For the present research, 125 participants older than 65 years of age (105 with hearing impairment and 20 with normal hearing) were enrolled, divided into 6 groups according to their degree of hearing loss and assessed to determine the effects of the treatment applied. Patients in our research program routinely undergo an extensive audiological and cognitive evaluation protocol providing results from the Digit Span test, Stroop color-word test, Montreal Cognitive Assessment and Geriatric Depression Scale, before and after rehabilitation. Data analysis was performed for a cross-sectional and longitudinal study of the outcomes for the different treatment groups. Each group demonstrated improvement after auditory rehabilitation or training on short- and long-term memory tasks, level of depression and cognitive status scores. Auditory rehabilitation by cochlear implants or hearing aids is effective also among older adults (median age of 74 years) with different degrees of hearing loss, and enables positive improvements in terms of social isolation, depression and cognitive performance.

The objective of our study was to review retrospectively the clinical, radiological and therapeutic findings in 62 adults with acute mastoiditis treated at the ENT Department of Ferrara from 1992 to 2010. 62 adult cases fulfilled the following inclusion criteria: otoscopical evidence of co-existent or recent otitis media; postauricular swelling, erythema or tenderness; protrusion of the auricle; fever and/or significant radiological findings of mastoiditis. Conservative treatment comprehended antibiotic ± ventilation tube. Surgical procedures comprehended mastoidectomy or mastoido-tympanoplasty. The incidence of adult's mastoiditis in our district (0.99 cases/year/100.000 inhabitants) has maintained quite stable during the considered 19-year period. The typical clinical presentation was observed in 48% of cases. Complications were meningitis (15 cases), meningo-encephalitis (1), meningitis associated with lateral sinus thrombosis (1), facial nerve paralysis (11), and labyrinthitis (8). In all cases except one, the facial palsy recovered completely and no mortality was observed due to these complications. Complete cure was obtained with conservative treatment in 69% of uncomplicated cases and in 24% of patients with intracranial complications. Mastoiditis in adults may present as the acute classical form, as well as latent forms which often have prolonged and insidious development followed by a rapid clinical deterioration. Clinical features are frequently atypical, while incidence of meningitis and other complications is still high particularly in the most elderly. Thus, great care is required from clinicians to make an early diagnosis in order to promote adequate treatment.

The threshold differences between patients with presbycusis with and without noise exposure were limited. Larger studies are needed to assess the relative effects of ageing and noise exposure on hearing thresholds.

BackgroundAt the present time, 50 to 60% of the population above 70 years of age suffers from a hearing impairment and from 0.6 to 1.1% has a severe to profound loss, which cannot benefit from an hearing aid. Moreover, it is expected that this prevalence will grow by more than two-fold in the next 40 years. There is strong evidence that hearing loss in older adults is associated with both cognitive load and social isolation, which in turn, are associated with cognitive and physical functioning. Cochlear implant (CI) dramatically improves sound audibility and speech understanding. The aim of this paper was to analyze outcome and complications of CI treatment in elderly patients.MethodsA retrospective study on 17 patients, aged at implantation between 65 and 79 years (mean = 70.47 ± 3.94), unilaterally implanted for severe to profound bilateral hearing loss. The following data were statistically evaluated: pre-implant pure-tone threshold and tests of speech recognition, both with hearing aid that without; post-implant threshold and speech perception with CI off and on. Moreover, statistical correlations of PTA improvement between two age groups (65 to 70 and over 70 years) were carried out.ResultsMean PTA improved from 111.25 (± 17.51) (pre-implant) to 43.81 (± 9.27) (post-implant); and the mean SRT improved from 90 dB to 65 dB. Moreover there was no statistical difference in PTA improvement between the two age groups (65 to 70 and over 70 years). No severe per- or post-operative surgical complications were noted.DiscussionIn the elderly, CI is a safe procedure that significantly improves hearing threshold (p < 0.00001) and speech perception (p < 0.01). Support of family and professionals, as well as duration of deafness and pre-implant scores greatly influence the results of rehabilitation and its perceived benefit. CI should not be denied in older individuals who are otherwise in good health.
