Hearing loss in prison inmates

Hearing, Auditory Processing, and Language Skills of Male Youth Offenders and Remandees in Youth Justice Residences in New Zealand

PURPOSE

International evidence suggests youth offenders have greater difficulties with oral language than their nonoffending peers. This study examined the hearing, auditory processing, and language skills of male youth offenders and remandees (YORs) in New Zealand.

METHOD

Thirty-three male YORs, aged 14-17 years, were recruited from 2 youth justice residences, plus 39 similarly aged male students from local schools for comparison. Testing comprised tympanometry, self-reported hearing, pure-tone audiometry, 4 auditory processing tests, 2 standardized language tests, and a nonverbal intelligence test.

RESULTS

Twenty-one (64%) of the YORs were identified as language impaired (LI), compared with 4 (10%) of the controls. Performance on all language measures was significantly worse in the YOR group, as were their hearing thresholds. Nine (27%) of the YOR group versus 7 (18%) of the control group fulfilled criteria for auditory processing disorder. Only 1 YOR versus 5 controls had an auditory processing disorder without LI.

CONCLUSIONS

Language was an area of significant difficulty for YORs. Difficulties with auditory processing were more likely to be accompanied by LI in this group, compared with the controls. Provision of speech-language therapy services and awareness of auditory and language difficulties should be addressed in youth justice systems.

Peripheral auditory assessment in minor head injury: a prospective study in tertiary hospital

Hearing loss is a common problem encountered in ENT practice. Hearing loss following head injury is a major medical problem in both adults and children, which may go unnoticed when it does not affect speech frequencies. Sensorineural hearing loss at high frequencies is a common finding in minor head injury. Patients with history suggestive of mild head injury (MHI) according to Glasgow coma scale score were evaluated. The most common cause of MHI was road traffic accidents involving two wheeler riders without helmets. Higher the frequencies affected, and severe the hearing loss, poorer was the prognosis. Distortion product oto-acoustic emissions assessment at 3000 and 4000 Hz were found to be significant and has a higher predictive value in assessing outer hair cell damage.

No Negative Outcomes of Childhood Middle Ear Disease in Adulthood

OBJECTIVES/HYPOTHESIS

To test the hypothesis that childhood middle-ear disease may have disadvantageous long-term psychosocial consequences in adulthood.

STUDY DESIGN

Prospective, longitudinal study of a general-population birth cohort.

METHODS

One thousand thirty-seven people born in 1972/73 were studied from birth to age 26 when 1,019 (96% of survivors) were followed up. Childhood otitis media was assessed, and effects of it have previously been observed in childhood and adolescence. We considered outcome measures that were plausible adult counterparts of the childhood constructs shown to be impaired by otitis media: socioeconomic status, employment status, educational outcomes, personality, mental health, antisocial and criminal behavior, and subjective ratings of personal health (SF-36).

RESULTS

No outcome measure was predicted by severity of childhood otitis media.

CONCLUSIONS

Adult psychological and socioeconomic outcomes are not related to childhood otitis media when appropriate treatment is available.

Hearing health of New South Wales prison inmates

OBJECTIVE

To assess the hearing health of New South Wales prison inmates.

METHODS

The method of testing hearing chosen was the rapid click-evoked otoacoustic emissions technique, from which two key variables were evaluated for early status of ear damage. Hearing variables, including hearing history and self-reported symptoms, were incorporated in a multivariate analysis of other health and demographic variables in the prison sample.

RESULTS

The analysis shows that the hearing acuity of prisoners is poor compared with the general Australian population. Variables significantly related to the hearing scores were history of hearing problems or having arthritis or diabetes. In this sample hearing did not interact with alcohol or drugs. Those testing positive for Hepatitis B Core-Antibody were also found to have poorer hearing than those without.

CONCLUSIONS AND IMPLICATIONS

Prisoners in general have poorer hearing than a normative Australian population. Some conditions have a significant impact on hearing, which may be due to associated medications. A previous history of ear problems was found to be significantly related to hearing acuity as was a history of exposure to noise. Health screening programs within the correctional system may need to include hearing loss prevention programs and medical follow-ups in relation to hearing health.

Progressive hearing loss after closed head injury: a predictable outcome?

OBJECTIVES

To evaluate the prevalence of progression of closed head injury (CHI)-induced hearing impairment, defined as > or = 15 dB HL deterioration at 1 or more frequencies, and to identify risk factors in patient history and initial status that could predict progression.

MATERIAL AND METHODS

A total of 600 patients with major CHI were admitted to 2 Swedish medical centres during a 14-year period. The type of injury was established by means of CT and the severity of head injury was measured using the Swedish Reaction Level Scale (RLS). In 62 of these patients, pure-tone audiometry was performed soon after the injury. Forty-three patients agreed to participate in the present investigation, which was carried out 2-13 years after the injury. Each participant was evaluated using pure-tone audiometry and an itemized anamnesis was obtained.

RESULTS

There was a higher prevalence of hearing impairments in the study group compared to a control group. Thirty-two subjects (74%,) showed a progression of > or = 15 dB, which was significantly greater than the spontaneous progression in the control group. Age and temporal bone fracture were risk factors for progression but not brain contusion only or RLS. There was an association between early pure-tone average (PTA) and progression as well as regression, i.e. the poorer the initial PTA the greater the progression as well as regression, indicating increased instability in the auditory system. Examination of patient histories did not reveal any single risk factors for progression. A serendipitous finding was a higher prevalence of reported memory shortcomings among those with post-traumatic tinnitus.

CONCLUSION

Especially for those with fracture of the temporal bone the present results stress the importance of audiometric evaluation and follow-up, from both rehabilitation and medicolegal perspectives,

Black English in a Mississippi prison population

Nine linguistic features unique to Black English were examined in the speech of 87 Black and 77 White inmates of a Mississippi prison population. The purpose of the study was to determine whether Black inmates could be distinguished from White inmates by their use of the present progressive, final stops, distributive be, remote aspect been, noun plurals, third person singular present tense, possessives, consonant clusters, and the copula. Results showed that use of eight of the nine features accurately predicted the ethnicity of the subjects. Only remote aspect been failed to identify ethnic differences. Identification of dialect variation among minority populations and more specifically among prison populations is an important step toward providing effective remediation programs.
