Introduction With the growing popularity of telemedicine and tele-diagnostics, clinical validation of new devices is essential. This study sought to investigate whether high-definition digital still images of the eardrum provide sufficient information to make a correct diagnosis, as compared with the gold standard view provided by clinical microscopy. Methods Twelve fellowship-trained ear physicians (neurotologists) reviewed the same set of 210 digital otoscope eardrum images. Participants diagnosed each image as normal or, if abnormal, they selected from seven types of ear pathology...

Hearing loss in patients with autoimmune diseases, such as systemic lupus erythematosus (SLE), granulomatosis with polyangiitis (GPA, Wegener's granulomatosis), or rheumatoid arthritis (RA), is controversial. Many studies lack measurements of bone-conduction thresholds to sufficiently differentiate between sensorineural hearing loss and conductive hearing loss. In addition, many studies lack control groups or comparisons to an age-related normal hearing threshold. This study investigates hearing performance with an extended audiological battery using psychoacoustic and objective measures...

OBJECTIVES: An important clinical application of transient-evoked otoacoustic emissions (TEOAEs) is to evaluate cochlear outer hair cell function for the purpose of detecting sensorineural hearing loss (SNHL). Double-evoked TEOAEs were measured using a chirp stimulus, in which the stimuli had an extended frequency range compared to clinical tests. The present study compared TEOAEs recorded using an unweighted stimulus presented at either ambient pressure or tympanometric peak pressure (TPP) in the ear canal and TEOAEs recorded using a power-weighted stimulus at ambient pressure...

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...

Otitis media (OM) is a common pediatric disease and nontypeable Haemophilus influenzae (NTHI) is the predominant pathogen in chronic OM, recurrent OM and OM associated with treatment failure. OM is also a polymicrobial disease, wherein an upper respiratory tract viral infection predisposes to ascension of NTHI from the nasopharynx, the site of colonization, to the normally sterile middle ear, resulting in disease. Using a clinically relevant viral-bacterial co-infection model of NTHI-induced OM, we performed transcutaneous immunization (TCI) via a bandaid delivery system to administer each of three promising NTHI vaccine candidates derived from bacterial adhesive proteins and biofilm mediators: rsPilA, chimV4 and integration host factor...

Compromised temporal resolving power of the auditory system can be one of the main factors contributing to poor speech perception skills in the elderly. Very few of the earlier studies have systematically examined this aspect. Hence, the current study was designed with the following objectives: 1) To establish normative database of Gaps in Noise (GIN) test in elderly population in an Indian context. 2) To determine the relationship between speech discrimination skills and temporal resolution abilities in elderly individuals with normal hearing sensitivity...

Degeneration of several brainstem nuclei has been long related to motor and non-motor symptoms (NMSs) of Parkinson's disease (PD). Nevertheless, due to technical issues, there are only a few studies that correlate that association. Brainstem auditory-evoked potential (BAEP) and vestibular-evoked myogenic potential (VEMP) responses represent a valuable tool for brainstem assessment. Here, we investigated the abnormalities of BAEPs, ocular VEMPs (oVEMPs), and cervical VEMPs (cVEMPs) in patients with PD and its correlation to the motor and NMSs...

Endonasal ballon dilatation of the Eustachian tube (BET) is a promising treatment for Eustachian tube dysfunction with encouraging results over the last years in adults. In addition, in children, single studies demonstrated promising results, but revealed the necessity for broader and additional studies. Our retrospective analysis presents outcomes with BET in children with chronic obstructive dysfunction of the Eustachian tube, showing resistance to the conventional therapy after adenotomy with paracentesis or grommets (ventilation tubes)...
