[The hearing function in the premature infants]

[Telerehabilitation of hearing-impaired children during COVID-19 pandemic]

OBJECTIVE

To evaluate advantages and effectiveness of remote rehabilitation services for hearing-impaired children at Center of Pediatric Audiology during COVID-19 pandemic.

MATERIAL AND METHODS

181 children with different types and degrees of permanent hearing loss, their parents and 10 hearing care professionals (audiologists, speech-language therapists) were included in the study. 2115 rehabilitation services were provided during 3 months: video- and text consultations, video lessons with child, sending homework to parents, etc.

RESULTS

The results of questionnaires showed that, on specialists' and parents' opinion, remote rehabilitation care is effective tool for hearing impaired children during emergency situations. TeleCare allowed to improve parents' abilities to manage with children by themselves, their understanding goals and methods of rehabilitation, improving child's hearing and speech skills. 95% of parents were satisfied by remote rehabilitation. Advantages and problems of remote hearing rehabilitation were analyzed from the sides of professionals and parents. The most challenging activities for professionals during TeleCare were: evaluation of HA/CI effectiveness, diagnosis and developing of hearing and speech.

CONCLUSIONS

The experience of remote hearing rehabilitation in emergency situation allows to conclude that this type of care could be useful in clinical practice after pandemic for parents consulting and for children with motor problems.

[The role of gastroesophageal reflux disease in the development of chronic exudative otitis media in the children during the first year of life]

The objective of the present study was the determination of the incidence of gastroesophageal reflux disease and the evaluation of its possible influence on the development and duration of chronic exudative otitis media in the children during the first year of life. A total of 141 infants at the age of 3 months presenting with exudative otitis media refractory to the conservative treatment throughout the first 1-1.5 months of life were available for the examination. The effectiveness of the anti-reflux therapy was estimated based on the middle ear condition (the presence or absence of exudate) within 3 and 6 months after the initiation of the treatment. The signs of aspiration of gastric chimus and gastroesophageal reflux disease were documented in 92% of the cases. The anti-reflux treatment during 3 months resulted in the disappearance of the manifestations of exudative otitis media in 43% of the patients. The further prolongation of such therapy up to 6 months allowed to normalize the state of the middle ear in 69% of the children although the remaining 40% failed to respond. It is concluded that the treatment of the children presenting with exudative otitis media during first year of life should be performed taking into consideration the possible involvement of gastroesophageal reflux disease in pathogenesis of this pathological condition.

[The relationship between the parameters of evoked otoacoustical emission and tympanometry in the children born with the extremely low body weight]

The objective of the present study was to elucidate correlation between the parameters of evoked otoacoustical emission at the distorsion product otoacoustic emissionen frequency (DPOAE) and the results of tympoanometry performed at the probe tone frequencies of 226 Hz and 1 kHz in the children born with the extremely low body weight. The results of the study give evidence of the moderate correlation dependence between the strength of the cochlear acoustic response at DPOAE and the cohlear response amplitude at the frequencies of 2 kHz and 6 kHz from TTP (r=0.3; p=0.000) obtained at the tympanometry probe tone frequency of 1 kHz. The correlation between the magnitude of the acoustic response of the cochlea, the amplitude of this response at the frequencies of 2 kHz and 6 kHz, the width of the tympanograms, and their static compliance obtained in the studies at the tympanometry probe tone frequency of 1,000 Hz (r=0.3-0.5; p=0.001) was documented in the infants at the age of 6 months and 1 year.
