Molecular Aspects

Congenital hypothyroidism (CH) is an endocrine disease commonly found in newborns and is related to the absence or reduction of thyroid hormones (THs), which are essential for development since intrauterine life. Children with CH can develop hearing problems as THs are crucial for the auditory pathway’s development and maturation. Sensory deprivations, especially in hearing disorders at early ages of development, can impair language skills, literacy, and behavioral, cognitive, social, and psychosocial development. In this review we describe clinical and molecular aspects linking CH and hearing loss.

Screening Survey

Background. The steadily growing number of hearing-impaired patients incited epidemiological research into the etiopathogenesis of sensorineural hearing loss.Objectives. To conduct a screening survey of hearing-impaired adults to identify early sensorineural hearing loss in patients with chronic general somatic pathology in the Republic of Adygea.Мethods. We used a screening method for auditory function disorder diagnosis based on surveying patients with no primary hearing complaints. A total of 6,346 patients with variant chronic general somatic pathology were surveyed anonymously. Statistical analysis and interpretation were performed with Statistica 10.0 and MS Excel 2010.Results. A point–based assessment survey of the patient’s psycho-emotional state in various classroom settings identifi ed the sensorineural disorder risk groups among the visitors of district and municipal outpatient units. Subclinical auditory function disorders were revealed in 16.5% (1045 of 6346), and putative hearing loss of various degree — in 36.2% (2295 of 6346) of the patients. In 47.3% (3006 of 6346), no evidence of hearing loss was observed in the survey. Accentuated analysis revealed early and severe hearing disorders among patients with cardiovascular, endocrine, nervous, excretory, respiratory and other diseases.Conclusion. We show the applicability of screening surveys for detecting early sensorineural hearing loss in patients with chronic general somatic pathology. Acceptance of adapted surveying by family physicians, neurologists and adult endocrinologists will facilitate preclinical identifi cation of risk groups among patients requiring specialised audiological care.

Occupational Hearing Loss

Exposure to industrial noise and the resulting effect of occupational hearing loss is a common problem in nearly all industries. This chapter describes industrial noise exposure, its assessment, and hearing disorders that result from overexposure to noise. Beginning with the properties of sound, noise-induced hearing loss and other effects of noise exposure are discussed. The impact of hearing disorders and the influence of other factors on hearing loss are described. Typically, noise-induced hearing loss develops slowly, and usually goes unnoticed until a significant impairment has occurred. Fortunately, occupational hearing loss is nearly always preventable. Therefore, this chapter gives particular attention to recommendations for measures to prevent occupational hearing loss such as engineering noise controls and hearing protection devices.

Conductive Hearing

Definition Hearing is the usual channel for acquisition of this most important of human attributes, language. Language enables humans to communicate at a distance and across time and has played a decisive role in the development of society and its many cultures. Language is the major channel through which children learn about what is not immediately evident, and it plays a central role in thinking and cognition. Because speech is the chief vehicle for communication in all families (except those in which the parents are deaf), deafness is a profound handicap whose effects greatly transcend the inability to speak. Responsibility for detecting hearing loss in infancy rests on the primary physician, inasmuch as early diagnosis and appropriate habilitation will prevent the most serious consequences of infantile hearing loss: growing up without language. Two primary types of hearing loss are attributable to disease of the ear: conductive hearing loss, a deficiency in the transduction of energy in the form of sound waves in air to hydraulic waves in the inner ear; and sensorineural hearing loss, inadequate transduction of these waves to neural activity. Other disorders of hearing include cortical hearing impairment and perceptual disorders. Although much is said about perceptual disorders by educators, such disorders probably play a minor role in the genesis of learning disabilities and will not be addressed in this review, which focuses on severe-to-profound hearing losses.

Целью исследования было изучение качества жизни лиц с нарушениями слуха в разных возрастных группах. Обследованы 100 пациентов, обратившихся в городской сурдологический центр для взрослых в связи с нарушением слуха: 50 человек - 34-59 лет, 50 - 60 лет и старше, из которых 32 человека были пожилого возраста (60-74 года)и 18 - старческого (75-86 лет). Степень тугоухости оценивали на основании результатов тональной пороговой аудиометрии. Для исследования качества жизни все пациенты заполняли общий опросник MOS SF-36, отражающий физический и психологический компоненты здоровья, а также специальный опросник HHIА(E)-S для лиц с нарушениями слуха. Установлено, что шкала HHIА(E)-S демонстрирует высокую корреляцию со степенью тугоухости у пациентов моложе 60 лет ( R =0,98; достоверность различий на уровне p <0,05), которая снижается у пациентов 60 лет и старше ( R =0,94; различия в оценках при разной степени тугоухости недостоверны). Значительные трудности в старшей возрастной группе могут быть связаны с тем, что людям пожилого и, особенно, старческого возраста сложно пользоваться слуховыми аппаратами (или они для них неэффективны) и оценивать свои затруднения по шкалам опросника. Целесообразно использовать шкалу HHIА(Е)-S в качестве скринингового инструмента для раннего выявления тугоухости, направления пациентов к сурдологу и своевременного слухопротезирования. The aim of the research was to study the quality of life in hearing impaired patients of different age. 100 patients referred to the city audiology centre because of their hearing disorders were examined: 50 patients from 34 to 59 years old and 50 patients from 60 years and older, from which 32 patients were of older age (60 to 74 years old) and 18 of oldest age (75 to 86 years old). A degree of hearing loss was assessed according to results of pure tone audiometry. To study the quality of life all patients filled in the questionnaire MOS SF-36, which evaluates physical and psychological components of health, and the questionnaire HHIA(E)-S, designed specifically for patients with hearing disorders. The HHIA(E)-S scale was found to show high correlation with hearing loss degree in patients younger than 60 years old ( R =0,98 with statistically significant difference, p <0,05), with decreasing correlation in patients from 60 years and older ( R =0,98; no significant difference while assessing various hearing loss degrees). Considerable difficulties in this age group may be explained by the fact, that older and especially oldest patients have a challenge with hearing aids usage (or they are of low efficiency for them) and with assessing theirs difficulties on the questionnaire scales. The HHIA(E)-S scale is useful as a screening tool for early detection of hearing loss, referral of patients to an audiologist and prompt hearing aid fitting.

OBJECTIVE: To identify the prevalence of hearing loss for the population in the urban area. METHODS: A cross-sectional household survey based on the World Health Organization Ear and Hearing Disorders Survey Protocol was conducted in 298 households in the urban area of Monte Negro, Rondonia, Northern Brazil, from 2005 to 2007. Ear examinations, behavioral audiometry and pure tone audiometry were conducted on 577 individuals. RESULTS: The results showed that 3.8% (95%CI 2.17;5.45) of population were classified in the disabling hearing impairment category. The prevalence of moderate hearing impairment was 3.4%; severe impairment was 0.4%; and profound hearing impairment was not found. CONCLUSIONS: The impairing hearing loss prevalence found in this study is within of the international prevalence for this level of hearing loss and smaller than observed in a previous study in the South region of Brazil.

Narrative Language

Purpose Narrative intervention has not been extensively investigated with children with hearing loss, but it has been shown to improve a broad range of language skills of children with a variety of disabilities and language needs. Therefore, the purpose of this study was to investigate the effect of narrative language intervention on the narrative retelling skills and vocabulary use of children with hearing loss. Method A multiple baseline design (for retelling) and a repeated acquisition design (for vocabulary) were used to fulfill the purpose of the study. Participants included two children ages 5 and 9 years diagnosed with bilateral sensorineural hearing loss, fitted to an amplification device. Each child received one 70-min session of individual narrative language intervention per week for at least 6 weeks that focused on teaching less common vocabulary words in addition to story grammar and complex sentences. Results Both participants demonstrated weekly increases in narrative retell scores and repeated pretest to posttest gains in the use of targeted vocabulary. Evidenced through visual analysis, both participants showed some growth in retell once intervention was introduced, with at least a modest upward trend each week. Moreover, vocabulary use scores, collected directly after intervention, showed both participants improved vocabulary use in familiar and untrained contexts. Conclusions Results suggest narrative language intervention improved the narrative retell ability and vocabulary use of children with hearing loss. Narrative intervention is a promising approach for promoting the language skills of children with hearing loss, but this finding requires replication.

Transient Congenital Hypothyroidism

Fetus and infants require appropriate thyroid hormone levels and iodine during pregnancy and lactation. Nature endorses the mother to supply thyroid hormones to the fetus and iodine to the lactating infant. Genetic variations on thyroid proteins that cause dyshormonogenic congenital hypothyroidism could in pregnant and breastfeeding women impair the delivery of thyroid hormones and iodine to the offspring. The review discusses maternal genetic variations in thyroid proteins that, in the context of pregnancy and/or breastfeeding, could trigger thyroid hormone deficiency or iodide transport defect that will affect the proper development of the offspring.
