Abstract
Individuals with dual sensory loss (DSL) appear to have limited ability to compensate for their visual impairment with residual hearing, or for their hearing impairment with residual vision, resulting in challenges in various areas of life. The aim of this qualitative study was to explore the diverse experiences facing individuals with DSL as well as to determine how they experience sensory compensation. Semi-structured interviews were carried out in twenty adults with DSL (13 females and 7 males, mean age 47 years). The causes of DSL severity varied amongst participants. Sensory compensation and experiences in regards to access to information, mobility, communication and fatigue were discussed. Interviews were audio recorded and transcribed verbatim. Framework analysis was used to summarize and interpret the data. In relation to access to information, our results show that, despite various challenges, the use of assistive technology such as voice command functions, enabled participants to operate effectively. Regarding mobility, most participants were capable of finding their way in familiar environments. However, if the setting was unfamiliar, assistance from others or reliance on navigation applications was necessary. Participants experienced little issues with having conversations in quiet settings, however, crowded settings were considered very difficult. The final results showed that most participants suffered from fatigue. Carefully considering which daily activities were feasible and having a daily routine helped to cope with fatigue. This study revealed the experiences of individuals with DSL in important areas of life. The results suggest that, even though many challenges are experienced, individuals with DSL are resourceful in finding compensation strategies. However, capturing participants' sensory compensation experiences was challenging.

Early audiological phenotype in patients with mutations in the USH2A gene. Int J Pediatr Otorhinolaryngol 2022; 157:111140.

Abstract
INTRODUCTION Nowadays, due to universal newborn hearing screening (UNHS) the number of children with mild-to-moderate hearing loss diagnosed in the first year of life has increased significantly. Aside from that, identification of the genetic cause improves the genetic counselling of the families and allows to reveal possible comorbidities which may need a special approach. OBJECTIVE To present the characteristics of the early audiologic phenotype in hearing impaired patients with biallelic mutations in the USH2A gene based on systematic analysis of the audiological data. PATIENTS AND METHODS 13 patients with mutations in the USH2A gene underwent audiological examination. Most of them were found among a large group of infants with bilateral nonsyndromic sensorineural hearing loss (SNHL) examined under 12 months. RESULTS Eight out of eleven children failed UNHS and were initially diagnosed as having bilateral nonsyndromic SNHL. Seven children underwent an audiological assessment before the age of 9 months. The earliest audiological examination was carried out at 1 and 3 months. The children with pathogenic variants in the USH2A gene in our examined group were identified in the first year of life via UNHS. The hearing threshold levels (HTL) for the USH2A group are compactly distributed between 51.25 dB and 66.25 dB, quartiles are 54 dB and 63.4 dB, with a median of 60 dB. The audiological profile of patients with biallelic USH2A mutations differs from audiograms of patients who had STRC-related hearing loss. We have not found any significant elevation in hearing thresholds in the first decade of life. We also estimated the prevalence of the USH2A and STRC mutations among GJB2-negative infants with bilateral nonsyndromic SNHL examined under 12 months, and it was 7.5% and 16.1%, respectively. CONCLUSION According to our results, the early hearing phenotype in pediatric patients with biallelic mutations in the USH2A- gene is characterized by nonsyndromic mild-to-moderate SNHL in the first decade of life. Our results indicate that the presence of mutations in the USH2A or STRC genes can be expected in a child with congenital mild-to-moderate nonsyndromic SNHL. This information is of practical importance for parents, as they have to know the prognosis of hearing loss for their child from the very beginning. Post-screening follow-up should include adequate clinical, genetic, and social support for children and their parents.

Abstract
Background: In Usher syndrome, deafness is congenital and blindness is acquired. Therefore, the progressive loss of one of the two senses forces individuals with this syndrome to reorganize their everyday tasks and relationships, creating new strategies to communicate, access information, and move within a given space. This reorganization can interfere with the subjects' capacity to build a good quality of life.Methods: We conducted a scoping review of both peer-reviewed and gray literature, to identify existing evidence of the role of psychosocial determinants on the quality of life of people with Usher syndrome.Results: Twenty-one references met the inclusion criteria. Findings suggest that people with Usher syndrome seem to adjust their life habits to their condition, maintaining hope for the future, and believe in their capacities to accomplish their goals in spite of the various difficulties they encounter. However, this scoping review highlights a lack of research on adaptive strategies, as well as a lack of knowledge concerning the integration of the syndrome in one's identity, the relations to caregivers, and the specificities of the psychotherapeutic support. More information on these topics would enable better-adjusted social, psychotherapeutic, and medical responses.Implications for rehabilitationUsher syndrome, a rare genetic disease, leads to deafblindness, a cluster of related multiple sensory disabilities. People with Usher encounter several obstacles in their daily life. It is also difficult to adapt to the progressive loss of hearing and sight.This paper proposes a scoping review: we identify the main adaptation strategies used by people with Usher Syndrome in order to become autonomous in spite of these obstacles. In becoming more autonomous, they come to a better quality of life.We summarize the most frequent adaptation strategies (at school, work, leisure, interpersonal relationships, etc.) to help programs aimed at rehabilitation for people with Usher syndrome, and to find unexplored research perspectives (e.g., psychotherapies).

Abstract
Hearing loss (HL) is one of the most common birth defects in developed countries and is a diverse pathologic condition with different classifications. One of these is based on the association with other clinical features, defined as syndromic hearing loss (SHL). Determining the cause of the HL in these patients is extremely beneficial as it enables a personalized approach to caring for the individual. Early screening can further aid in optimal rehabilitation for a child's development and growth. The advancement of high-throughput sequencing technology is facilitating rapid and low-cost diagnostics for patients with SHL.

Abstract
Deafness is the most frequent sensory disorder. With over 90 genes and 110 loci causally implicated in non-syndromic hearing loss, it is phenotypically and genetically heterogeneous. Here, we investigate the genetic etiology of deafness in four families of Iranian origin segregating autosomal recessive non-syndromic hearing loss (ARNSHL). We used a combination of linkage analysis, homozygosity mapping, and a targeted genomic enrichment platform to simultaneously screen 90 known deafness-causing genes for pathogenic variants. Variant segregation was confirmed by Sanger sequencing. Linkage analysis and homozygosity mapping showed segregation with the DFNB57 locus on chromosome 10 in two families. Targeted genomic enrichment with massively parallel sequencing identified causal variants in PDZD7: a homozygous missense variant (p.Gly103Arg) in one family and compound heterozygosity for missense (p.Met285Arg) and nonsense (p.Tyr500Ter) variants in the second family. Screening of two additional families identified two more variants: (p.Gly228Arg) and (p.Gln526Ter). Variant segregation with the hearing loss phenotype was confirmed in all families by Sanger sequencing. The missense variants are predicted to be deleterious, and the two nonsense mutations produce null alleles. This report is the first to show that mutations in PDZD7 cause ARNSHL, a finding that offers addition insight into the USH2 interactome. We also describe a novel likely disease-causing mutation in CIB2 and illustrate the complexity associated with gene identification in diseases that exhibit large genetic and phenotypic heterogeneity.
