Hearing assessment of 14 children suffered from urinary tract infection and treated by amikacin is reported. The dosage of amikacin was 7.5 mg/kg/daily for 10 days and the serum level of amikacin not exceeded the 35 mcg/ml. The aim of the study was on the one hand to determine the hearing damaging side effect of amikacin and on the other to assess the usefulness of objective methods for detection of hearing loss in this population. Authors used for screening a transient otoacoustic emission (TEOAE) during and after (2-4 weeks) therapy. If subjective and objective (TEOAE) methods gave a good result, no further checkup has considered as necessary, but if there were no evoked emission, acoustic brainstem response audiometry has been carried out for verification. It result no hearing loss could be detected in the measured specimen. In conclusion it has been stated that by proper dosage and serum level screening amikacin may no lead to hearing loss in children, and objective methods are valuable for hearing screening and monitoring of such population of children.

Sensorineural hearing loss causes cell death in central auditory neurons, but molecular mechanisms of triggering this process are not fully understood. We report here that loss of afferent activity promotes cell death by facilitating proBDNF-p75NTR signals in cochlear nucleus of chicks around hatch. RNA-seq analyses revealed up-regulation of genes related to proBDNF-p75NTR-JNK signals as well as apoptosis at the nucleus within 24hours after unilateral cochlea deprivation.

This study contributes to the conceptualisation of preventive interventions in schools to address potential issues so that these children can play a more active role in society.
Methods: A total of 52 children (aged 3-12 years) who received CIs at 30 months of age were assessed using the Asahide-Shiki Social Adaptive skills test, which evaluates children's social skills on four domains: (A) language, (B) everyday life, (C) social life, (D) communication.

In the adult mammalian cochlea, hair cell loss is irreversible and causes deafness. The basic helix-loop transcription factor Atoh1 is essential for normal hair cell development in the embryonic ear. Over-expression of Atoh1 in the adult cochlea by gene therapy can convert supporting cells (cells that underlie hair cells) into a hair cell lineage.

Objective: The study aimed to explore the vestibular function in children with neurodevelopmental disorders (NDDs).
Methods: Twenty-eight participants with a NDD (6 girls, 22 boys; 6-13 years; 9;3 ± 2;4 years) were enrolled in this pilot study. Sixteen participants had a single NDD (Autism Spectrum Disorder: n = 7, Developmental Coordination Disorder: n = 3; Attention Deficit/Hyperactivity Disorder: n = 6), the remaining 12 had comorbid NDDs.

Purpose: This study aimed to investigate the incidence and characteristics of sudden sensorineural hearing loss (SSNHL) in pregnant and non-pregnant women using the Korean National Health Insurance Service customized cohort data.
Materials And Methods: We defined the delivery group as women aged 15-49 years with International Classification of Diseases 10th Revision codes O80-O84 indicating delivery between January 2013 and December 2019. The control group was selected from individuals in the same age range without a history of delivery during the same period.
