Twenty years ago, we described a kindred of 105 individuals with isolated GH deficiency (IGHD) in Itabaianinha County, in Brazilian northeast, due to a homozygous mutation in the GH-releasing hormone receptor gene. These subjects exhibit markedly reduced GH responsiveness to stimulatory tests, and anterior pituitary hypoplasia. Serum concentrations of IGF-I, IGF binding protein type 3, and the acid-labile subunit are markedly reduced, with a lesser reduction of IGF-II. The most striking physical findings of these IGHD individuals are the proportionate short stature, doll facies, high-pitched voice, and visceral obesity with reduced fat free mass...

Hearing loss (HL) is the most common birth defect. Elucidating the genetic basis of hereditary deafness can not only assist diagnosis, provide the basis for genetic counseling and the prevention of deafness, but also bring a deeper understanding of the disease pathogenesis. In the genomic era, high-throughput sequencing technologies, represented by whole genome sequencing (WGS), whole exome sequencing (WES) or target region sequencing, have been widely used in the studies of hereditary HL. Here, we summarize the application and progress of WES and target region sequencing in the research of causative genes and clinical molecular diagnosis of hereditary HL, hoping to be helpful for the development and improvement of clinical genetic diagnosis of deafness in China...

BACKGROUND: Heritage speakers acquire their native language from home use in their early childhood. As the native language is typically a minority language in the society, these individuals receive their formal education in the majority language and eventually develop greater competency with the majority than their native language. To date, there have not been specific research attempts to understand word recognition by heritage speakers. It is not clear if and to what degree we may infer from evidence based on bilingual listeners in general...

BACKGROUND: Auditory complaints following mild traumatic brain injury (MTBI) are common, but few studies have addressed the role of auditory temporal processing in speech recognition complaints. PURPOSE: In this study, deficits understanding speech in a background of speech noise following MTBI were evaluated with the goal of comparing the relative contributions of auditory and nonauditory factors. RESEARCH DESIGN: A matched-groups design was used in which a group of listeners with a history of MTBI were compared to a group matched in age and pure-tone thresholds, as well as a control group of young listeners with normal hearing (YNH)...

BACKGROUND: Chronic tinnitus (phantom perception of sound) significantly disrupts quality of life in 15-20% of those who experience it. Understanding how certain personality traits impact tinnitus perception and distress can be beneficial for the development of interventions to improve the lives of tinnitus sufferers. PURPOSE: Four key self-reported personality traits (social closeness, stress reaction, alienation, and self-control) were identified from previous research as being associated with tinnitus...

The objective of this paper is to review current information regarding the treatment of age-related hearing loss by using cochlear hair cell regeneration. Recent advances in the regeneration of the inner ear, including the usefulness of stem cells, are also presented. Based on the current literature, cochlear cell regeneration may well be possible in the short term and cochlear gene therapy may also be useful for the treatment of hearing loss associated with ageing. The present review provide further insight into the pathogenesis of Inner Ear senescence and aged-related hearing loss and facilitate the development of therapeutic strategies to repair hair cells damaged by ageing...

OBJECTIVE: There is some evidence to suggest that safety on small area farms may not be high priority due to economic constraints and lack of knowledge. This has important ramifications for injury and economic burden. The objective of this research was to conduct a pilot study to investigate whether small to medium area farms implement fewer safety practices than large farms. METHODS: Farmers were recruited from farm safety training days, field days and produce stores in rural New South Wales (NSW), Australia...

Speech perception is inherently a multisensory process involving integration of auditory and visual cues. Multisensory integration in cochlear implant (CI) recipients is a unique circumstance in that the integration occurs after auditory deprivation and the provision of hearing via the CI. Despite the clear importance of multisensory cues for perception, in general, and for speech intelligibility, specifically, the topic of multisensory perceptual benefits in CI users has only recently begun to emerge as an area of inquiry...

OBJECTIVES: A reliable and practical measure of listening effort is crucial in the aural rehabilitation of children with communication disorders. In this article, we propose a novel behavioral paradigm designed to measure listening effort in school-age children based on different depths and levels of verbal processing. The paradigm consists of a classic word recognition task performed in quiet and in noise coupled to one of three additional tasks asking the children to judge the color of simple pictures or a certain semantic category of the presented words...

REVIEW
Nicole L Davis, Caroline C King, Athena P Kourtis
Cytomegalovirus (CMV) is a DNA herpesvirus that is common worldwide. The two known main sources of primary CMV infection during pregnancy are through sexual activity and contact with young children. Primary infection occurs in approximately 1 to 4% of pregnancies, and is mostly asymptomatic in immunocompetent adults. However, primary infection may manifest as a mild mononucleosis or flu-like syndrome with persistent fever and fatigue. CMV can be transmitted from mother-to-child in utero, intrapartum, or during breastfeeding...

BACKGROUND: Noise-induced hearing loss (NIHL) is an increasingly growing problem in young children. This is attributed to recreational noise being the most common cause of this problem. In young children, hearing problems can delay language development and reduce academic achievements. South Africa, in particular, has limited information and protective measures regarding the conservation of hearing in school-aged children. OBJECTIVES: The main aim of the study was to determine the perception of primary school teachers regarding NIHL...

Y Zhang, B Liu
Meniere disease is a unique, progressive disease of the inner ear. The complex manifestation presents diagnostic challenges. It is difficult to diagnose due to the absence of typical presentations especially in the early stages. The cochlear symptoms often present prior to vertigo and tend to be ignored. Therefore, focusing on the cochlear symptoms and functions may provide information for early diagnosis and may protect the patients from acquiring a hearing disability. This review focused on the pure-tone audiometry, glycerin test, distortion product otoacoustic emissions, auditory brainstem response, electrocochleogram, multifrequency tympanometry, and speech audiometry, which hopefully could emphasize the importance of the symptomatic and functional findings of cochlear, and be helpful in diagnosis for Meniere disease...

Children's hearing is a public health concern, and universal newborn hearing screenings are the first step in detecting and treating congenital hearing loss. Despite the high rate of participation in such programs, loss to follow-up (LTF) with additional recommended diagnosis and treatment has been a persistent problem. The current research seeks to expand the knowledge base at the point of diagnosis, where there is a large drop-off in parents following through with recommended care. This research was organized around the following question: What biopsychosocial factors are associated with LTF between screenings and diagnostic evaluations? A prospective quantitative longitudinal study tracked 203 families whose newborns were referred for additional testing at discharge from the hospital after birth...

INTRODUCTION: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstrate the hearing outcome after a modification of the incus interposition technique, which involved preserving it in the periauricular soft tissue...

Acoustic trauma is the most common cause of hearing loss and tinnitus in humans. However, the impact of acoustic trauma on system biology is not fully understood. It has been increasingly recognized that tinnitus caused by acoustic trauma is unlikely to be generated by a single pathological source, but rather a complex network of changes involving not only the auditory system but also systems related to memory, emotion and stress. One obvious and significant gap in tinnitus research is a lack of biomarkers that reflect the consequences of this interactive "tinnitus-causing" network...

Angela Woods
Hearing voices in the absence of another speaker-what psychiatry terms an auditory verbal hallucination-is often associated with a wide range of negative emotions. Mainstream clinical research addressing the emotional dimensions of voice-hearing has tended to treat these as self-evident, undifferentiated and so effectively interchangeable. But what happens when a richer, more nuanced understanding of specific emotions is brought to bear on the analysis of distressing voices? This article draws findings from the 'What is it like to hear voices' study conducted as part of the interdisciplinary Hearing the Voice project into conversation with philosopher Dan Zahavi's Self and Other: Exploring Subjectivity, Empathy and Shame to consider how a focus on shame can open up new questions about the experience of hearing voices...
