It is widely accepted that middle ear pathology can cause dizziness and imbalance, however this has been a challenging area to investigate, as the bi-thermal caloric test is difficult to interpret in this cohort. Recently vestibular tests that bypass the middle ear have been developed. These are the Video Head Impulse Test (vHIT) and the Bone Conduction Vestibular Evoked Myogenic Potentials (BC-VEMPs). We have successfully carried out pre-operative vHIT and BC-VEMPs on 20 patients awaiting surgery for middle ear pathologies and have shown that complete testing can be done in less than 30 minutes...

BACKGROUND: The electrically evoked stapedial reflex threshold (ESRT) has been shown to be a good predictor of upper stimulation level for cochlear implant recipients. Previous research has shown that the ESRT may be recorded at lower stimulation levels and with a higher incidence of success with the use of higher frequency probe tones (e.g., 678 and 1000 Hz) relative to the use of the conventional 226-Hz probe tone. Research has also shown that the acoustic reflex may be recorded at lower stimulus levels with the use of wideband reflectance when compared to the acoustic reflex threshold recorded with a conventional acoustic immittance measurement...

BACKGROUND: One of the most important steps for good user performance with a cochlear implant (CI) is activation and programming, aimed at determining the dynamic range. In adults, current levels are determined by psychophysical measures. In babies, small children, or individuals with multiple disorders, this procedure requires techniques that may provide inconsistent responses because of auditory inexperience or the age of the child, making it a very difficult process that demands the collaboration of both the patient and the family...

BACKGROUND: Hearing loss (HL) is classified as conductive when sound transmission is compromised in the ear canal or middle ear, or sensorineural when there is an abnormality of the receptor cells of the cochlea or auditory pathway. Hearing in dogs is evaluated using the brainstem auditory evoked response (BAER) test. HYPOTHESIS/OBJECTIVES: Our objective was to characterize BAER findings pre- and post-ear flushing in four dogs with acute HL following application of an ointment-based otic medication containing betamethasone, clotrimazole and gentamicin in a mineral oil-based system containing a plasticized hydrocarbon gel...

Polycotylidae is a clade of plesiosaurians that appeared during the Early Cretaceous and became speciose and abundant early in the Late Cretaceous. However, this radiation is poorly understood. Thililua longicollis from the Middle Turonian of Morocco is an enigmatic taxon possessing an atypically long neck and, as originally reported, a series of unusual cranial features that cause unstable phylogenetic relationships for polycotylids. We reinterpret the holotype specimen of Thililua longicollis and clarify its cranial anatomy...

BACKGROUND: This is an update of a Cochrane review first published in The Cochrane Library in Issue 4, 2008 and previously updated in 2011.Acute suppurative otitis media is one of the most common infectious diseases in childhood. Recurrent acute otitis media is defined for the purposes of this review as either three or more acute infections of the middle ear cleft in a six-month period, or at least four episodes in a year. Strategies for managing the condition include the assessment and modification of risk factors where possible, repeated courses of antibiotics for each new infection, antibiotic prophylaxis and the insertion of ventilation tubes (grommets)...

BACKGROUND: Preoperative illnesses might induce immunosuppression and subsequently increase morbidity after surgery. Several studies have tried to identify risk factors for complications after hypospadias correction, but effects of illnesses in the weeks just before surgery are unknown. We aimed to determine the associations between preoperative illnesses not severe enough to postpone surgery and short-term complications after hypospadias repair in children. METHODS: In this retrospective cohort study, data were collected from 681 children with anterior or middle type hypospadias that had initial one-stage repair in the period 1983-2012 in the Radboudumc, The Netherlands...

Introduction  Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment. Objective  To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases...

Hee-Seung Choi, Minji Seo, Hyung-Taeg Cho
Auxin signaling is finalized by activator auxin response factors (aARFs) that are released from Auxin/Indole-3-Acetic Acid (Aux/IAA) repressors and directly activate auxin-responsive genes. However, it remains to be answered how repressor ARFs (rARFs) exert their repression function. In this study, we assessed the molecular and biological functions of two putative co-repressor-binding motifs (EAR and RLFGI) of ARF2 (a rARF) in Arabidopsis thaliana . In the yeast two-hybrid assay, the EAR mutation moderately and the RLFGI mutation, or both motifs, almost completely disrupted the interaction between the co-repressor TOPLESS (TPL) and the repressive motifs-containing middle domain (MD) of ARF2...

Evaluation of middle ear function in infants is the key to distinguish sensorineural hearing loss and conductive hearing loss, and acoustic immittance test is the routine audiological evaluation of middle ear function.Because of the characteristics of middle ear in infants, middle ear examination parameters of adults are not suitable for infants. This article reviewd the current multiple acoustic immittance methods for detecting middle ear function in infants, and summarized the advantages and disadvantages of these methods...

Despite advances in treatment and prevention, the pneumococcus continues as a dominant cause of severe pneumonia and sepsis, of otitis media, sinusitis and nonbacteremic pneumonia. Lewnard and colleagues use a unique data set of nasopharyngeal and middle ear fluid samples to provide further insight into the progression of nasopharyngeal pneumococcal colonization to disease. They report the comparative rate of progression from colonization to otitis media by serotype, providing insight as to how conjugate vaccines that do not reduce the overall presence of pneumococci in the nasopharynx dramatically impact the incidence of acute and complex otitis media...

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis...
