“…Two separate Nigerian studies indicated a prevalence of 4.9% in a sample of children diagnosed with SNHL [45] and 13.5% in a cohort of children with severe-profound hearing loss [44]. Hyperbilirubinemia has been associated as the most commonly reported risk factor for ANSD, varying between 30 to 70% [38,[46][47][48].…”

“…These costs in themselves may prohibit hearing aid use in many developing countries. Annual costs for hearing aid cells may be greater than the yearly income of an African subsistence farming family (Lasisi, Ayodele, & Ijaduola, 2006). Noninstrument-related factors are also very important.…”

Trends in Amplification

Hearing instrument technology research is almost entirely focused on the projected needs of the consumer market in the developed world. However, two thirds of the world's population with hearing impairment live in developing countries and this proportion will increase in future, given present demographic trends. In developing regions, amplification and other hearing health needs may differ from those in industrialized nations, for cultural, health, or economic reasons. World Health Organization estimates indicate that at present only a small percentage of individuals in developing countries who are in need of amplification have access to hearing aid provision. New technologies, such as trainable hearing aids, advanced noise reduction algorithms, feedback reduction circuitry, nano coatings for hearing aid components, and innovative power options, may offer considerable potential benefits, both for individuals with hearing impairment in developing countries and for those who provide hearing health care services in these regions. This article considers the possible supporting role of innovative hearing instrument technologies in the provision of affordable hearing health care services in developing countries and highlights the need for research that considers the requirements of the majority of the world population in need of hearing instrument provision.

“…Нарушения слуховой функции, как правило, связаны с дыха-тельной недостаточностью, в том числе стойкой легочной гипертензией, экстракорпоральной мем-бранной оксигенацией, а также с нарушением кро-вообращения. Кроме того, причинами тугоухости у данной группы пациентов могут быть ятроген-ные факторы, такие как искусственная вентиляция легких, использование ототоксических лекарств, длительное зондовое питание [8,15,17]. В связи с тяжелым состоянием детям с ВПС неонатальный скрининг слуха часто не проводится.…”

The auditory function of infants with congenital heart diseases

et al. 2017

Congenital heart disease (CHD) is 1/3 of all congenital malformations and one of the main causes of infant mortality. Hearing loss may be part of syndromes associated with CHD, or the hearing pathology can be a consequence of the various stages of rehabilitation of underlying pathology. Currently, there isn’t any data on the systematic study of hearing impairment in children with congenital cardiac pathologies. Three hundred and six patients aged 2 days to 8.5 months were examined: 96 patients were included in the main group with CHD, and 300 children without CHD made up a comparison group. All children underwent newborn hearing screening. Infants with suspected hearing pathology were tested with a comprehensive audiological examination. In the CHD group hearing impairment was detected in 29% of children, including sensorineural hearing loss (SNHL) in 12%. And in the comparison group, 3.6% of infants had a hearing loss, SNHL was defined in 1%. Analysis of the data revealed the most significant risk factors for hearing impairments in children with CHD and it had showed the difference in the structure of the risk factors between the both groups. In the study group was registered a case of auditory neuropathy spectrum disorders. This case illustrated the importance of conducting hearing screening by means of click-evoked auditory brainstem responses and not only of registration of otoacoustic emissions. One child with CHD was found to have delayed SNHL, which requires long-term monitoring of hearing in children with cardiopathology.
