OBJECTIVE: Given ongoing debate about the suggested association, the primary objective was to determine if idiopathic sudden sensorineural hearing loss (ISSNHL) was a sentinel event for acute myocardial infarction (AMI) in adults. STUDY DESIGN: Case-control study. SETTING: United States MarketScan administrative health claims database. PATIENTS: Aged 18 years or older, had a diagnosis of ISSNHL on or after January 1st, 2011 and had sufficient follow-up data available to assess for AMI occurrence...

HYPOTHESIS: Connexin-26 (Cx26) expression is diminished in the spiral ligament of subjects with hearing loss and cochlear otosclerosis (CO). BACKGROUND: Human temporal bone (HTB) studies have demonstrated that CO is associated with hyalinization of the spiral ligament. We hypothesize that hyalinization is associated with a loss of fibrocytes with a consequent decline in Cx26 expression. Cx26 and Connexin-30 (Cx30) encode gap junction proteins expressed in supporting cells of the organ of Corti, the spiral limbus, stria vascularis, and in fibrocytes of the spiral ligament...

Ischemia and oxidative stress play crucial roles in the pathophysiology of sudden sensorineural hearing loss (SSNHL). Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine and serves an important role in hearing function. The present study was designed to evaluate the effect of MIF on oxygen-glucose deprivation (OGD)-induced ototoxicity and to elucidate its molecular mechanism. In HEI-OC1 auditory cells, OGD reduced cell viability and increased supernatant lactate dehydrogenase (LDH) and MIF in a time-dependent manner...

Purpose: This study investigates whether 4π noncoplanar radiation therapy can spare the cochleae and consequently potentially improve hearing preservation in patients with acoustic neuroma who are treated with radiation therapy. Methods and materials: Clinical radiation therapy plans for 30 patients with acoustic neuroma were included (14 stereotactic radiation surgery [SRS], 6 stereotactic radiation therapy [SRT], and 10 intensity modulated radiation therapy [IMRT])...

Thiamine-responsive megaloblastic anaemia (TRMA) is a syndrome associated with megaloblastic anaemia, diabetes mellitus and sensorineural deafness, due to mutations in the SLC19A2 gene, which codes for a thiamine carrier protein. Oral thiamine supplementation is the main treatment. We report the case of a 25-year-old woman known for TRMA, who presented with pancytopenia (haemoglobin 7.6 g/dL, leucocytes 2.9×109 /L, thrombocytes 6×109 /L) revealed by dyspnoea. Investigations excluded coagulopathy, a recent viral infection, vitamin and iron deficiencies, and a malignant process...

BACKGROUND: Resection of a vestibular schwannoma may result in facial paralyiss and hearing loss on the side of tumor. Authors have encountered a young female of neurofibromatosis type 2, who developed contralateral side sensorineural hearing loss immediately after resection of vestibular schwannoma.The patient regained partial hearing with a short course (2 months) of steroid therapy over 6 month. MATERIAL AND METHODS: Clinical, audiological, intraoperative events and radiological parameters were evaluated in this case...

The inward rectifier potassium (Kir) channel Kir4.1 (KCNJ10) carries out important physiological roles in epithelial cells of the kidney, astrocytes in the central nervous system, and stria vascularis of the inner ear. Loss-of-function mutations in KCNJ10 lead to EAST/SeSAME syndrome, which is characterized by epilepsy, ataxia, renal salt wasting, and sensorineural deafness. While genetic approaches have been indispensable for establishing the importance of Kir4.1 in the normal function of these tissues, the availability of pharmacological tools for acutely manipulating the activity of Kir4...

HYPOTHESIS: A cochlear implant (CI) restores hearing in patients with profound sensorineural hearing loss by electrical stimulation of the auditory nerve. It is unknown how this electrical stimulation sounds. BACKGROUND: Patients with single-sided deafness (SSD) and a CI form a unique population, since they can compare the sound of their CI with simulations of the CI sound played to their nonimplanted ear. METHODS: We tested six stimuli (speech and music) in 10 SSD patients implanted with a CI (Cochlear Ltd)...

BACKGROUND: To describe the clinical and genetic findings in a Chinese family with three sibs diagnosed with Usher syndrome type IIC. MATERIALS AND METHODS: Four members received ophthalmic and otologic tests to ascertain the clinical characteristics. According to the clinical phenotype, we focused attention on a total of 658 genes associated with them. We screened the possible pathogenic mutation sites, used Sanger to exclude the false positive and verified whether there were co-segregated among the family members...

OBJECTIVES: Chronic low-back pain (CLBP) participants in a prior controlled study reported short-term pain relief after caudal epidural injection of 5% dextrose (D5W). This study assessed whether repeated caudal epidural injections of D5W results in serial short-term diminution of CLBP and progressive long-term decrease in pain and disability. DESIGN: Prospective uncontrolled study. SETTINGS/LOCATION: Outpatient pain clinic. SUBJECTS: Adults with CLBP with radiation to gluteal or leg areas...

INTRODUCTION: Since 1996 the active middle-ear implant Vibrant Soundbridge (VSB) is used to treat mild-to-severe sensorineural hearing losses. The former standard surgical approach for incus vibroplasty included a mastoidectomy and a posterior tympanotomy, crimping the Floating-Mass Transducer (FMT) to the long incus process. The introduction of the short process (SP) coupler allows the attachment of the FMT to the incus body making the procedure of a posterior tympanotomy unnecessary...

PURPOSE: Alport syndrome is a rare condition characterized by the clinical triad of nephritic syndrome, sensorineural deafness, and ophthalmological alterations. Herein, we present a rare case of a patient diagnosed with Alport syndrome and bilateral giant macular holes. CASE DESCRIPTION: A 40-year-old woman with a previously unreported mutation in the COL4A4 gene suggestive of autosomal-recessive Alport syndrome presented at our department.

Objective: To investigate the therapeutic effect of psychological intervention combined with diazepam on sudden hearing loss patients with anxiety. Method: 108 cases of sudden hearing loss patients with anxiety were randomly divided into two groups( n =54 in each group): The control group received routine treatment of sudden hearing loss, the study group was given psychological intervention combined with diazepam tablets(2.5 mg once, twice a day) based on the routine treatment. The hearing and HAMA and SAS scores were reviewed after 10 days of treatment...
