Hearing aid rehabilitation of hearing disorders in adults

Hearing-aid provision is still partly a medical task, in spite of technological progress and a confusing variety of types and models of devices. The diagnosis of the underlying disease, the appreciation of the consequences of hearing loss and the counseling of the hearing impaired person are prerequisites of the treatment. The physician should try to determine the etiology of the hearing loss. Also, a state-of-the-art otologic examination should be performed and the physician should be sensitive to the psychological and social consequences of the patient's hearing loss. For the assessment of fitted hearing aids, basic knowledge of the technical background is required. To measure hearing-aid benefit in the ENT office, suprathreshold and speech audiometry are indispensable tools.     

Hearing aid use and benefit and uptake of aural rehabilitation services by New Zealand hearing aid wearers

AIM: To provide the first extensive survey in New Zealand of hearing aid use and benefit and the accessibility of Hearing Association services. METHOD: A mail-out questionnaire was used to survey 197 Auckland adult hearing aid wearers regarding patterns of hearing aid use and benefit and the accessibility of Hearing Association aural rehabilitation services. RESULTS: Hearing aid benefit was moderate and was not related to age or hearing aid use variables. Knowledge and usage of local rehabilitation services was limited. Perceived functions of the Hearing Association included adult audiometry and counselling. Respondents wanted assistance with hearing aid management and assistive listening devices. Physical access, financial and time constraints were seen as barriers to using rehabilitative services. DISCUSSION: It appears that there is not a simple relationship between perceived benefit or satisfaction and the amount of time people wear their hearing aids. The low level of awareness and participation in Hearing Association services is consistent with the underutilisation of such services found previously.     

Hearing loss in community-dwelling older persons: national prevalence data and identification using simple questions

OBJECTIVE: To estimate the prevalence of hearing loss among community-dwelling older persons according to clinical criteria and to develop a brief self-report screening instrument to detect hearing loss. DESIGN: Survey. SETTING: National probability sample of noninstitutionalized older persons. PARTICIPANTS: A total of 2506 persons aged 55 to 74 who participated in the National Health and Nutrition Examination Survey. MAIN OUTCOME MEASURES: Hearing loss as defined by Ventry and Weinstein (VW) criteria and by the High Frequency Pure-Tone Average (HFPTA) scale. RESULTS: Hearing loss by VW criteria was present in 14.2% and by HFPTA criteria in 35.1% of those surveyed. The prevalence increased with advancing age and was higher among men and those with less education. A logistic regression model identified six independent factors for hearing loss by VW criteria: age > or = 70 years (adjusted odds-ratio (AOR) 2.7, 95% confidence interval (95% CI) 1.6, 4.4), male gender (AOR 3.0, 95% CI 1.9, 4.8), < or = 12th grade education (AOR 3.8, 95% CI 1.8, 7.7), having seen a doctor for deafness or hearing loss (AOR 8.9, 95% CI 5.3, 14.9), unable to hear a whisper across a room (AOR 3.2, 95% CI 2.0, 5.1), and unable to hear a normal voice across a room (AOR 6.2, 95% CI 2.6, 14.9). A clinical scale based on the logistic model had 80% sensitivity and 80% specificity in predicting hearing loss using VW criteria and 59% sensitivity and 88% specificity in predicting hearing loss using HFPTA criteria. CONCLUSIONS: Hearing loss, as defined by two clinical criteria, is common and can be screened for accurately using simple questions that assess sociodemographic and hearing-related characteristics.     

Effects of depressive symptoms on health behavior practices among older adults with vision loss.

Objective: The authors examined the interface between visual impairment and depressive symptoms on health behaviors, self-care, and social participation among adults ages 65 and older. Method: The authors analyzed data from the 1997–2004 National Health Interview Survey on visual impairment and depressive symptoms for 49,278 adults ages 65 and older, comparing visually impaired adults (n = 8,787) with and without depressive symptoms with a reference group of adults with neither condition (n = 3,136) for outcome measures: physical health, health behaviors, and difficulties with self-care and social participation. Results: Adults with visual impairment and severe depressive symptoms were more likely than adults with neither condition to smoke (14.9%, adjusted odds ratio [AOR] = 1.6), be obese (28.2%, AOR = 1.9), be physically inactive (80.5%, AOR = 3.0), have fair–poor health (76.0%, AOR = 26.5), and have difficulties with self-care (27.9%, AOR = 11.8) and social participation (52.1%, AOR = 10.9). Discussion and Conclusions: Older visually impaired adults with depressive symptoms are vulnerable to health decline and further disablement without timely interventions that target smoking cessation, healthy eating, and increased physical activity.

Physical status as a moderator of depressive symptoms among older adults with dual sensory loss.

Objective: This study evaluated the ability of three measures of physical status—physical activity, physical condition, and body mass index (BMI)—to moderate the relationship between dual sensory loss (DSL) and depressive symptoms in older adults. Method: Nationally representative longitudinal data were used to develop multilevel models predicting depressive symptoms among two groups of older adults, 1380 who developed DSL during the study and 1308 without sensory loss. Results: All three measures were associated with depressive symptoms for persons who had or would develop a DSL: participation in physical activity and being in better physical condition were associated with lower levels of depressive symptoms, while lower BMI levels were associated with higher levels of depressive symptoms. All moderator variables had a larger effect for persons with DSL as compared to persons without sensory loss. Implications: The implication of these findings is that participation in a regular program of physical activity may provide multiple benefits to older persons with DSL. Families and health care providers can offer support for being physically active by ensuring the person has the best possible correction for the sensory losses, providing encouragement, and/or providing physical assistance with exercise.

Loss of appetite: managing unwanted weight loss in the older patient

Loss of appetite, regardless of cause, is a significant symptom that may cause extreme weight loss in older patients. The consequences of anorexia include muscle wasting, weakness, depression, increased susceptibility to disease complications, and decreased immunocompetence. In the older population, the major causes of anorexia are pulmonary and cardiac diseases, cancer, dementia, alcoholism, depression, and medications. The diagnosis is based on the physical exam, a history of weight loss, and a review of dietary intake. Treatment strategies include managing GI disturbances, encouraging physical activity and socialization, reducing fatigue and food aversions, and adding high-calorie supplements to the diet.     

Children with minimal sensorineural hearing loss: prevalence, educational performance, and functional status

OBJECTIVE: This study was designed to determine the prevalence of minimal sensorineural hearing loss (MSHL) in school-age children and to assess the relationship of MSHL to educational performance and functional status. DESIGN: To determine prevalence, a single-staged sampling frame of all schools in the district was created for 3rd, 6th, and 9th grades. Schools were selected with probability proportional to size in each grade group. The final study sample was 1218 children. To assess the association of MSHL with educational performance, children identified with MSHL were assigned as cases into a subsequent case-control study. Scores of the Comprehensive Test of Basic Skills (4th Edition) (CTBS/4) then were compared between children with MSHL and children with normal hearing. School teachers completed the Screening Instrument for Targeting Education Risk (SIFTER) and the Revised Behavior Problem Checklist for a subsample of children with MSHL and their normally hearing counterparts. Finally, data on grade retention for a sample of children with MSHL were obtained from school records and compared with school district norm data. To assess the relationship between MSHL and functional status, test scores of all children with MSHL and all children with normal hearing in grades 6 and 9 were compared on the COOP Adolescent Chart Method (COOP), a screening tool for functional status. RESULTS: MSHL was exhibited by 5.4% of the study sample. The prevalence of all types of hearing impairment was 11.3%. Third grade children with MSHL exhibited significantly lower scores than normally hearing controls on a series of subtests of the CTBS/4; however, no differences were noted at the 6th and 9th grade levels. The SIFTER results revealed that children with MSHL scored poorer on the communication subtest than normal-hearing controls. Thirty-seven percent of the children with MSHL failed at least one grade. Finally, children with MSHL exhibited significantly greater dysfunction than children with normal hearing on several subtests of the COOP including behavior, energy, stress, social support, and self-esteem. CONCLUSIONS: The prevalence of hearing loss in the schools almost doubles when children with MSHL are included. This large, education-based study shows clinically important associations between MSHL and school behavior and performance. Children with MSHL experienced more difficulty than normally hearing children on a series of educational and functional test measures. Although additional research is necessary, results suggest the need for audiologists, speech-language pathologists, and educators to evaluate carefully our identification and management approaches with this population. Better efforts to manage these children could result in meaningful improvement in their educational progress and psychosocial well-being.     

Cigarette smoking and hearing loss: the epidemiology of hearing loss study

CONTEXT: Clinical studies have suggested that cigarette smoking may be associated with hearing loss, a common condition affecting older adults. OBJECTIVE: To evaluate the association between smoking and hearing loss. DESIGN: Population-based, cross-sectional study. SETTING: Community of Beaver Dam, Wis. PARTICIPANTS: Adults aged 48 to 92 years. Of 4541 eligible subjects, 3753 (83%) participated in the hearing study. MAIN OUTCOME MEASURES: The examination included otoscopy, screening tympanometry, and pure-tone air-conduction and bone-conduction audiometry. Smoking history was ascertained by self-report. Hearing loss was defined as a pure-tone average (0.5, 1, 2, and 4 kHz) greater than 25-dB hearing level in the worse ear. RESULTS: After adjusting for other factors, current smokers were 1.69 times as likely to have a hearing loss as nonsmokers (95% confidence interval, 1.31-2.17). This relationship remained for those without a history of occupational noise exposure and in analyses excluding those with non-age-related hearing loss. There was weak evidence of a dose-response effect. Nonsmoking participants who lived with a smoker were more likely to have a hearing loss than those who were not exposed to a household member who smoked (odds ratio, 1.94; 95% confidence interval, 1.01-3.74). CONCLUSIONS: These data suggest that environmental exposures may play a role in age-related hearing loss. If longitudinal studies confirm these findings, modification of smoking habits may prevent or delay age-related declines in hearing sensitivity.     

Hearing in the elderly. Relation of hearing loss, loneliness, and self-esteem

1. The prevalence of hearing impairment increases with age. Hearing handicap resulting from hearing loss may lead to psychosocial problems in elders. 2. Previous studies have shown relations among hearing handicap, loneliness and low self-esteem, but those studies focused on populations other than elders. 3. Early detection of hearing handicap and appropriate interventions promote increased independence and preserve the ability of elders to interact with their environment.     

Aided speech recognition abilities of adults with a severe or severe-to-profound hearing loss

Adults with severe or severe-to-profound hearing losses constitute between 11% and 13.5% of the hearing-impaired population. A detailed investigation of the speech recognition of adults with severe (n = 20) or severe-to-profound (n = 14) hearing loss was conducted at The University of Melbourne. Each participant took part in a series of speech recognition tasks while wearing his or her currently fitted hearing aid(s). The assessments included closed-set tests of consonant recognition and vowel recognition, combined with open-set tests of monosyllabic word recognition and sentence recognition. Sentences were presented in quiet and in noise at +10 dB SNR to replicate an environment more typical of everyday listening conditions. Although the results demonstrated wide variability in performance, some general trends were observed. As expected vowels were generally well perceived compared with consonants. Monosyllabic word recognition scores for both the adults with a severe hearing impairment (M = 67.2%) and the adults with a severe-to-profound hearing impairment (M = 38.6%) could be predicted from the segmental tests, with an allowance for lexical effects. Scores for sentences presented in quiet showed additional linguistic effects and a significant decrease in performance with the addition of background noise (from 82.9% to 74.1% for adults with a severe hearing loss and from 55.8% to 34.2% for adults with a severe-to-profound hearing loss). Comparisons were made between the participants and a group of adults using a multiple-channel cochlear implant. This comparison indicated that some adults with a severe or severe-to-profound hearing loss may benefit from the use of a cochlear implant. The results of this study support the contention that cochlear implant candidacy should not rely solely on audiometric thresholds.     

Age and the sense of control among older adults

Older adults are expected and frequently found to report less control than younger adults. In this study, we decompose this negative relationship between age and sense of control using nested multivariable linear regression models that serially introduce sociodemographic characteristics, socioeconomic factors, health status, and subjective religiosity and religious beliefs in a sample of 1,051 older adults attending the general medicine clinics of a major medical center. The results indicate that the effect of age is suppressed in the bivariable model. In the final multivariable model, educational attainment has the largest relative effect (i.e., beta; .253), followed by age (-.210), mental health (.174), subjective religiosity (.113), being an African American (-.100), perceived health (.082), and being Catholic (.068). Future research should focus on the inflection point in the relationship between age and the sense of control that apparently occurs at about 50 years of age.     

Patterns of expenditures and use of services among older adults with diabetes. Implications for the transition to capitated managed care

BACKGROUND: Rapid quantifiable diagnostic techniques for the diagnosis of cytomegalovirus (CMV) infection may predict patients at risk of CMV pneumonitis and allow preemptive antiviral treatment. METHODS: Using CMV antigenemia as a prospective surveillance technique for CMV infection, we compared the outcome of preemptive treatment (PT) with ganciclovir, 10 mg/kg/day for 21 days directed by "high levels" of CMV antigenemia (PT group, n= 19), with the outcome in a group of historical controls (n=18) treated with ganciclovir when CMV illness occurred. Greater than 50 antigen-positive cells per 2 x 10(5) polymorphonuclear leukocytes was considered to be high-level antigenemia. RESULTS: Nine of the 18 controls developed high-level CMV antigenemia at a median of 33 days (range: 13-65 days) and 5 of the 9 developed CMV disease. Ten of the 19 PT group had high levels of CMV antigenemia detected at a median of 47 days (range: 20-63 days) and were given ganciclovir; none developed CMV disease. There was a significantly lower incidence of CMV disease in the PT group in comparison to controls (0 of 19 vs. 5 of 18: P=0.019). CONCLUSION: We have reduced the incidence of CMV disease using preemptive treatment, and because of a 100% negative predictive value, we omitted unnecessary antiviral prophylaxis for many at-risk patients.     

Association of symptoms of depression with diagnostic test charges among older adults

BACKGROUND: Previous studies have documented greater use of health services by depressed persons and have postulated that health care costs could be reduced overall through better recognition and treatment of depression. OBJECTIVE: To determine whether a greater burden of medical illness contributes to excess charges for diagnostic tests among older adults with symptoms of depression. DESIGN: Prospective cohort study. SETTING: A primary care group practice at an academic institution. PATIENTS: 3767 patients 60 years of age and older who completed testing on the Centers for Epidemiologic Studies Depression Scale (CES-D) during routine office visits. MEASUREMENTS: Charges for all inpatient and ambulatory diagnostic testing for 2 years, including clinical pathology, diagnostic imaging, and special procedures; number of visits to the ambulatory care center or emergency department; and number of hospitalizations. The Ambulatory Care Group case-mix approach, which is based on ambulatory diagnoses, was used as a measure of health status and expected resource consumption. RESULTS: Patients with symptoms of depression (CES-D scores > or = 16) were significantly younger (66.6 compared with 68.1 years; P < 0.001), more likely to be white (50.5% compared with 33.9%; P = 0.001), and more likely to be female (75.8% compared with 67.6%; P = 0.001) than were those without these symptoms (CES-D scores < 16). They also had more nonpsychiatric comorbid conditions, had more visits to the ambulatory care center (9.2 compared with 7.8; P < 0.001), were more likely to use the emergency department (52.3% compared with 40%; P = 0.001), were more likely to be hospitalized (22.4% compared with 17%; P = 0.002), and had greater median total diagnostic test charges for a period of 1 year ($583 compared with $387; P < 0.001). The difference in charges, most of which were clinical pathology charges (54.2%), persisted into the second year. Ambulatory Care Group assignment was independently associated with diagnostic test charges. The CES-D summary score was not independently associated with diagnostic test charges when controlling for Ambulatory Care Group assignment. CONCLUSIONS: Patients with symptoms of depression accrue greater average diagnostic test charges. However, these data suggest that such patients also have a greater burden of comorbid nonpsychiatric illness. Efforts to improve outcome and decrease cost for patients who have late-life depression must target interventions to improve the care of psychiatric and medical illness concurrently.     

Chronic conductive hearing loss in adults: effects on the auditory brainstem response and masking-level difference

Chronic desquamative gingivitis (DG) is a common condition often first recognized by periodontists. DG is characterized clinically by erythema with epithelial desquamation, ulceration, and/or the presence of vesiculobullous lesions of the free and attached gingiva. However, DG is actually a clinical manifestation of several different disease processes, particularly lichen planus and benign mucous membrane pemphigoid. Correct diagnosis in DG is critical since proper treatment and follow-up will depend on which disease is involved. However, the diseases that cause DG frequently present diagnostic problems because their lesions often resemble each other clinically and routine histological examination sometimes cannot differentiate between them. Thus, immunohistology, particularly immunofluorescence, is increasingly being used with routine histology to more accurately diagnose DG diseases. This article reviews our experience over the past 10 years in the diagnosis of 72 cases of DG using direct immunofluorescent (DIF) in conjunction with histology and clinical evaluation. Of the 72 DG cases in this study, 30 cases were diagnosed as erosive lichen planus or lichenoid mucositis; 29 cases were diagnosed as benign mucous membrane pemphigoid; 2 cases each of linear IgA disease and pemphigus vulgaris were diagnosed; there was 1 case of bullous pemphigoid; and 1 suspected case of paraneoplastic pemphigus. Even with DIF analysis, 7 cases could not be definitively assigned a particular cause. DIF analysis is not only proving very useful for differential diagnosis, but also adds insight into possible pathogenic mechanisms of DG.     

Social support sources among older women with heart failure: continuity versus loss over time

In the mosquito Culex pipiens one of the major resistance mechanisms to organophosphorous pesticides (OPs) is increased detoxification of insecticide. This resistance is the consequence of overproduction of two types of esterases, esterases A and B, coded at two loci, Est-3 (A esterase) and Est-2 (B esterase). We have analysed the genomic structure of these genes in different strains resistant to OPs and have attempted to characterize the different types of mutations leading to the resistant phenotypes. It is shown that, concerning the more frequent resistant phenotypes, mutations leading to resistance are of two main types. First, overproduction of one A esterase present in Southern France results from a regulatory mechanism. The second type of mutation is gene amplification which involves events that have initially generated the duplication of both the A and B esterase or only the B esterase locus. We report the point that the most frequent esterase overproductions are the results of eight different mutations and that, given the range of distribution of these genotypes, mutation leading to an efficient resistance gene is one of the most limiting factors for the evolution toward resistance in Culex pipiens.     

Perceptions of academic quality among students with a hearing loss in distance education.

There has been little research on the experiences of students with a hearing loss in mainstream higher education. This investigation compared perceptions of academic quality in 265 students with a hearing loss who were taking courses by distance learning and 178 students taking the same courses who had no declared form of disability. Students who were classified as hard of hearing (rather than deaf) produced significantly lower ratings of the appropriateness of their academic workload than did the students with no declared disability, but the ratings produced by students who were classified as deaf were not significantly different from those produced by the comparison group, In other respects, the students with a hearing loss were remarkably similar to the students with no declared disability in their perceptions of academic quality and their overall satisfaction with their courses, (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hearing loss and vestibular dysfunction in childhood from the use of streptomycin in Albania

OBJECTIVE: To analyze which factors, including gynecological surgery in particular, contribute to the occurrence of pelvic relaxation. METHOD: A retrospective analysis of 711 consecutive patients treated surgically for pelvic relaxation from 1983 to 1989 at the Department of Obstetrics and Gynecology of Turku University Central Hospital was undertaken. RESULT: The patients who underwent surgery for recurrent pelvic relaxation were significantly older (66.8 vs. 62.1 years) and suffered significantly less (20% vs. 41%) from urinary stress incontinence than patients undergoing primary surgery for pelvic relaxation. Anterior vaginal segment relaxation (i.e. cysto- and urethrocele) was common in patients undergoing the initial operation (n = 684), and posterior vaginal segment relaxation (i.e. rectocele and perineal laceration) in recurrent operations (n = 58). Of the patients studied, 87 had pelvic relaxation, which had developed after partial (n = 46), total abdominal (n = 16) or vaginal (n = 25) hysterectomy. CONCLUSION: Care must be taken in the treatment of the posterior vaginal segment during the initial operation for pelvic relaxation in order to avoid late sequelae. Moreover, when the removal of the uterus is planned, the matter of a stable vaginal vault must be taken into account especially when partial hysterectomy should be performed.     

Obese, older adults with knee osteoarthritis: Weight loss, exercise, and quality of life.

This study examined the effects of dietary weight loss and exercise on the health-related quality of life (HRQL) of overweight and obese, older adults with knee osteoarthritis. A total of 316 older men and women with documented evidence of knee osteoarthritis were randomly assigned to 1 of 4 18-month interventions: dietary weight loss, exercise, dietary weight loss and exercise, or healthy lifestyle control. Measures included the SF-36 Health Survey and satisfaction with body function and appearance. Results revealed that the combined diet and exercise intervention had the most consistent, positive effect on HRQL compared with the control group; however, findings were restricted to measures of physical health or psychological outcomes that are related to the physical self.
