Abstract
OBJECTIVE: To develop and validate a digitally recorded speech test battery to assess speech perception in Jordanian Arabic-speaking adults.
DESIGN: Selected stimuli were digitally recorded and were divided into four lists of 25 words each. Speech audiometry was completed for all listeners. Participants were divided into two equal groups of 30 listeners each with equal male to female ratio. The first group of participants completed speech reception thresholds (SRTs) and word recognition testing on each of the four lists using a fixed intensity. The second group of listeners was tested on each of the four lists at different intensity levels in order to obtain the performance-intensity function.
STUDY SAMPLE: Sixty normal-hearing listeners in the age range of 19-25 years. All participants were native speakers of Jordanian Arabic.
RESULTS: Results revealed that there were no significant differences between SRTs and pure tone average. Additionally, there were no differences across lists at multiple intensity levels.
CONCLUSIONS: In general, the current study was successful in producing recorded speech materials for Jordanian Arabic population. This suggests that the speech stimuli generated by this study are suitable for measuring speech recognition in Jordanian Arabic-speaking listeners.

Statistical tool to detect small hearing threshold shifts.

Int J Audiol. 2017 Mar 23;:1-11

Authors: Tronstad TV

Abstract
OBJECTIVE: The aim of this study is to present a new tool that can be used in the prevention of noise-induced hearing loss. Even in most countries where noise levels are well regulated, many workers are still exposed to high levels of noise and suffer from permanent threshold shifts. It is necessary to develop a new strategy to prevent such damage.
METHOD: A statistical process control (SPC) scheme is presented that is able to detect both large and small hearing threshold shifts. Monte Carlo simulations were used to assess the performance of this hearing monitoring scheme. Different hearing threshold shifts were simulated to evaluate the performance of a variety of hearing development scenarios.
RESULTS: It is possible to detect hearing threshold shifts smaller than the standard deviation of the hearing tests performed. This means that permanent hearing threshold shifts smaller than 5 dB can be detected and acted on. Outliers can also be automatically detected and treated, increasing the robustness of the monitoring scheme.
CONCLUSION: The proposed statistical framework can be used as an early warning indicator of noise-induced hearing loss with the aim of improving workers' safety. Individual counteractions can be implemented, reducing the risk of further damage.

Hearing aid use in the elderly as measured by datalogging and self-report.

Int J Audiol. 2017 Mar 23;:1-8

Authors: Solheim J, Hickson L

Abstract
OBJECTIVES: The primary aim was to compare the objective and the subjective assessments of hearing aid use among elderly people at a 6-month follow-up after fitting. A secondary aim was to determine whether advanced knowledge of follow-up impacts hearing aid use.
DESIGN: Hearing aid use was assessed by datalogging (objective) and self-report (subjective) 6 months after initial fitting. Participants were also randomised to an intervention (informed of 6-month follow-up at fitting) or control group (informed just prior to follow-up).
STUDY SAMPLE: A total of 181 hearing aid recipients ≥60 years (mean age = 79.2 years).
RESULTS: Daily hearing aid use based on datalogging (mean = 6.12 h, SD = 4.94) was significantly less than self-reports (mean = 8.39 h, SD = 5.07). More severe hearing impairment and prior hearing aid experience were associated with increased hearing aid use. Advanced knowledge of the follow-up had no significant impact on use, which did not differ between intervention (n = 93) and control (n = 88) groups.
CONCLUSIONS: Elderly people typically use their hearing aids for a substantial part of the day in the 6 months after fitting, but tend to overestimate their usage. Datalogging is recommended to identify those who do not use or rarely use their aids so that appropriate rehabilitation and support can be provided.

The parents' perspective of the early diagnostic period of their child with hearing loss: information and support.

Int J Audiol. 2017 Mar 23;:1-12

Authors: Scarinci N, Erbasi E, Moore E, Ching TY, Marnane V

Abstract
OBJECTIVE: This study aimed to explore the perspectives of caregivers regarding the information and support they received following diagnosis of their child's hearing loss.
DESIGN: A mixed methods explanatory sequential design was conducted.
STUDY SAMPLE: A total of 445 caregivers of children completed a written survey, and five parents participated in qualitative in-depth interviews.
RESULTS: The most common sources of information for caregivers were discussion with an audiologist, written information, and discussion with a medical professional. Approximately 85% of caregivers reported they were satisfied with the personal/emotional support and information received from service providers. Additional comments from 91 caregivers indicated that 11% experienced a breakdown in information transfer with health professionals. Interviews conducted with five parents from three families revealed two themes which described the diagnostic period as a difficult and emotional experience for parents: (1) support and information provided during diagnosis: what happens first? and (2) accessing early intervention services following a diagnosis of hearing loss: navigating the maze.
CONCLUSIONS: The findings of this study give insight into the perspectives of caregivers who have a child diagnosed with hearing loss. The importance of providing timely information and personal/emotional support to caregivers cannot be underestimated.

BCAP31-associated encephalopathy and complex movement disorder mimicking mitochondrial encephalopathy.

BCAP31-associated encephalopathy and complex movement disorder mimicking mitochondrial encephalopathy.

Am J Med Genet A. 2017 Mar 23;:

Authors: Albanyan S, Teneiji AA, Monfared N, Mercimek-Mahmutoglu S

Abstract
BCAP31, encoded by BCAP31, is involved in the export of transmembrane proteins from the endoplasmic reticulum. Pathogenic variants in BCAP31 results in global developmental delay, dystonia, deafness and dysmorphic features in males, called deafness, dystonia, and cerebral hypomyelination (DDCH) syndrome. We report a new patient with BCAP3-associated encephalopathy, DDCH syndrome, sensorineural hearing loss, generalized dystonia, and choreoathetosis. This 3.5-year-old boy had microcephaly and failure to thrive within the first 3 months of life. His brain MRI showed bilateral increased signal intensity in globus pallidus at age 3 months raising the suspicion of mitochondrial encephalopathy. His muscle biopsy revealed pleomorphic subsarcolemmal mitochondria collection in electron microscopy. Respiratory chain enzyme activities were normal in muscle. He was enrolled to a whole exome sequencing research study, which identified a hemizygous likely pathogenic truncating variant (c.533_536dup; p.Ser180AlafsX6) in BCAP31, inherited from his mother, who had sensorineural hearing loss and normal cognitive functions. We report a new patient with BCAP31-associated encephalopathy, DDCH syndrome, mimicking mitochondrial encephalopathy. We also report a heterozygous mother who has bilateral sensorineural hearing loss. This patient's clinical features, muscle histopathology, brain MRI features, and family history were suggestive of mitochondrial encephalopathy. Whole exome sequencing research study confirmed the diagnosis of BCAP31-associated encephalopathy, DDCH syndrome.

Transcanal Endoscopic Ear Surgery for Middle Ear Cholesteatoma.

Objective: To evaluate the clinical parameters, outcomes, and complications of transcanal endoscopic ear surgeries for middle ear cholesteatoma. Study Design: Retrospective study. Setting: Tertiary university-affiliated medical center. Patients: Adult patients (age >18) who underwent transcanal endoscopic ear surgeries for cholesteatoma, between March 2009 and March 2015. Intervention: Transcanal endoscopic surgery was indicated when the cholesteatoma did not extend posterior to the anterior limb of the lateral semicircular canal. Rigid endoscopes 4 and 2.7 mm in diameter, 0, 30, 45, and 70 degrees were used with angled picks, suction, and forceps. Preoperative assessment included high-resolution computed tomography of the temporal bones and/or non echo-planar diffusion-weighted magnetic resonance imaging and pure-tone audiometry. Main Outcome Measures: Residual or recurrent disease was diagnosed by clinical examination and/or magnetic resonance imaging findings consistent with cholesteatoma. Intra- and postoperative complications, pre- and postoperative audiometric results were recorded. Results: Sixty operations (56 patients, mean age = 43.6) were included. Six operations (10%) were performed under local anesthesia. The most common sites of cholesteatoma involvement were: posterior epitympanum (n = 51, 91%), anterior epitympanum (n = 19, 33.9%), posterior mesotympanum (n = 13, 23.2%), and sinus tympani (n = 11, 19.6%). Intraoperative ossicular chain reconstruction was performed in 18 (30%) cases. Our overall residual and recurrence rates were 10% (n = 6) and 8.3% (n = 5), respectively, with mean duration of follow up of 35 months. The most common sites of residual disease were the mastoid cavity/antrum (n = 3, 50%), tympanic cavity, and posterior mesotympanum. Overall minor and major complication rates were 16.6 and 6%, respectively. Conclusions: Transcanal endoscopic ear surgery was found to be an acceptable and safe technique for the exposure and eradication of middle ear and/or attic cholesteatoma.

Arteriovenous Lesions of the Internal Auditory Canal.

Objective: To describe a unique case of an asymptomatic arteriovenous lesion of the internal auditory canal (IAC) and present the associated imaging findings. Methods: Retrospective case report and review of the literature. Results: A 55-year-old man presented for further evaluation of a left-sided sudden sensorineural hearing loss that occurred 8 years earlier. Careful review of outside serial magnetic resonance (MR) imaging revealed a contralateral, ill-defined right-sided IAC mass with low T2 signal and subtle peripheral enhancement on postcontrast T1-weighted sequencing. The patient had no history of right-sided otologic symptoms. Subsequent dedicated IAC MR imaging confirmed the presence of a space-occupying lesion adjacent to a complexity of vasculature. The presence of prominent flow voids, paucity of avid enhancement on previous studies, and marked signal within the lesion on time-of-flight MR angiography and MR venography was consistent with the diagnosis of a solitary arteriovenous lesion of the IAC. There was no radiological evidence of recent or remote parenchymal or subarachnoid hemorrhage or stroke. Conclusion: We report a novel case of an occult asymptomatic IAC arteriovenous lesion. Vascular anomalies confined to the IAC are rare. To date, there have been only four reports in the literature of IAC arteriovenous lesions and our case is the first to present asymptomatically. A high index of suspicion and dedicated imaging is required to identify and accurately diagnose these lesions to guide appropriate counseling and potential intervention.

Cochlear Implant in Severe Impaired Psychiatric Patients: A Case Series.

Objective: Psychotic disorders and intelligence deficiencies are no longer contraindications for cochlear implantation regarding the revised German guidelines from May 2012. This article aims to evaluate the outcome of patients with severe psychiatric comorbidities. Therefore the database of the Cochlear Implant Center of the University Hospital of Heidelberg was investigated. Study Design: Retrospective case review. Methods: We present three patients who received a cochlear implant (CI) despite a serious psychiatric disorder. Two were sent from psychiatrists asking if a CI was possible for their profound hearing loss. One patient had acoustic hallucinations and a recurrent depressive disorder, the other had a schizophrenic psychosis and a minor impairment of intelligence. The third patient had a recurrent depressive disorder, a posttraumatic stress disorder, a chronic pain disorder, and paranoid personality traits. We discuss the preoperative diagnosis, course of diseases, and psychosocial situation. Results: All three patients received a CI and rehabilitation in the Cochlear Implant Center of the University Hospital of Heidelberg. All three of them opted for a second implant and developed a good hearing outcome. Free field understanding of words in quite is for all three of them over 60% in the Freiburger monosyllable test with two implants, similar to nonpsychiatric patients' results. No patient has acceptance problems. In the long run, no aggravation of the psychiatric diseases occurred. Conclusion: With interdisciplinary evaluation, a cochlear implantation is possible in severely impaired psychiatric patients. For a good result the indication is to be discussed interdisciplinary.

Impact of Chronic Suppurative Otitis Media in Pediatric Cochlear Implant Recipients-Insight into the Challenges from a Tertiary Referral Center in UK.

Objective: Analyze the presentation and evolution of chronic suppurative otitis media (CSOM) in children with cochlear implants (CI) and explore the merit of early intervention. Study Design: Retrospective patient review. Setting: Tertiary referral hospital and cochlear implant programme. Patients: Children with a CI who developed CSOM. Intervention: Tympanoplasty. Main Outcome Measures: Disease control, recurrence of cholesteatoma, cochlear implant preservation. Results: Eight children fit our inclusion criteria with a mean follow up of 8 years. Onset of CSOM symptoms was observed on an average of 5 years after implantation (range, 2-13 yr) and led to surgical intervention in an average of 15.6 months following symptom onset. Cholesteatoma was found in four of the eight patients. Of these, one patient underwent a subtotal petrosectomy and explantation with reimplantation at the same stage but the reimplant failed to function and was explanted subsequently. One patient was initially managed by a canal wall up mastoidectomy and explantation but went on to require subtotal petrosectomy and labyrinthectomy for recurrent disease. One patient underwent a subtotal petrosectomy with explantation and is awaiting a reimplantation. The fourth patient had limited disease around the electrodes that was excised without compromising the implant. In the group of patients with CSOM without cholesteatoma, one underwent an explantation due to recurrent ear infections and a subsequent cartilage tympanoplasty for a retracted eardrum. The remaining three patients underwent successful excision of retraction pockets and repair of eardrums using cartilage with the implant in situ. A mean follow up of 2 years after the implant preservation surgeries shows good functioning of the CI. Conclusion: Early recognition of CSOM is paramount in patients with CI as delay in treatment can result in the infection spreading via the cochleostomy resulting in loss of the cochlea. Recurrent ear infections in an implanted ear should prompt early examination to exclude the presence of middle ear disease, which may require anesthesia in a young child.

The Normal Adult Human Internal Auditory Canal: A Volumetric Multidetector Computed Tomography Study.

Objective: The purpose of this study was to demonstrate that volumetric analysis of multidetector computed tomography (CT) images can be used to calculate the volume of the adult human internal auditory canal (IAC) reproducibly, and to describe the range of normal IAC volumes in the adult population with subgroup analysis of sex, age, and laterality. Background: Previous studies of the IAC have typically used measurements in two dimensions or by using casts of cadavers to measure IAC volumes. This study is the first to report the normal ranges of IAC volumes measured by CT. Methods: Two hundred eighty-one CT scans were assessed. Of the CT scans that met the inclusion criteria, a software package was used to manually contour the IACs in each subject to calculate the volumes in cubic millimeters. Subgroup analysis of laterality, sex, and age was evaluated. Interobserver agreement was calculated for the first 59 patients (118 canals). Results: Two hundred fifty-nine scans (518 canals) met the inclusion criteria. The volumes ranged from 74 to 502 mm3, with no statistically significant difference between left and right (p value = 0.69). In males, the range of volumes measured 74 to 502 mm3 while in females it ranged from 78 to 416 mm3. Males had larger IAC volumes than females (Wilcoxon rank-sum test: S = 14,845.0, p value = 0.01 on the right, and S = 14,646, p value = 0.004 on the left). No correlation was found with age (Spearman: -0.10, p value = 0.09 on the right and -0.04, p value = 0.50 on the left). Excellent interobserver agreement was found. Conclusion: IAC volumes of normal adult subjects, measured by CT, were larger in males and not significantly different with respect to age or laterality.
