The purpose of the study is to study the clinicopathologic behaviour of the 3 dangerous types of chronic otitis media that are prone for complications. In which type are the complications more common? Which type gives rise to more hearing loss? How does the disease process in the 3 types evolve? should the 3 types of otitis media be managed differently?

This study is designed to check the effect of the use of the ear popper device on serous otitis media in children and on the conductive hearing loss accompanying the otitis. It is intended...
The study is a randomized controlled trial. Subjects are randomly assigned 1:1 to receive either rapid multiplex qPCR (intervention) prior to standard of care prostate biopsy or standard o...
ear swabs will be collected from 120 patients with established CSOM at the ear-nose-throat (ENT) outpatient clinic at the Ziv medical center, and 120 swabs will be taken from children with...
The purpose of this clinical study is to obtain clearance for the nasal swab sample type by demonstrating the performance characteristics of the FLU A+B Test versus standard laboratory cul...
The purpose of this study is to discover how often certain bacteria are found in the rectum at the time of a prostate needle biopsy to diagnose prostate cancer. Certain bacteria are of imp...
Chronic otitis media is described as a tympanic membrane perforation and ear discharge for more than six weeks duration. Ascending infection from the nasopharynx into the middle ear cleft has been att...
A number of diseases of the middle ear are summed up under the term otitis media: acute otitis media, recurrent acute otitis media, otitis media with effusion, chronic suppurative otitis media and chr...
Gradenigo syndrome was defined as a clinical triad of otitis media, severe orbito-facial pain, and ipsilateral sixth cranial nerve palsy. It may occur as a complication of either acute or chronic otit...
Transrectal prostate biopsies carry the risk of infection. By using non-selective culture plates, instead of commonly used ciprofloxacin (CIP)-containing plates, we analyzed the association between Es...
To detect the prevalence of fungus in chronic suppurative otitis media-cholesteatoma disease and to evaluate its clinical significance.
A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry.
The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.
Inflammation of the ear, which may be marked by pain (EARACHE), fever, HEARING DISORDERS, and VERTIGO. Inflammation of the external ear is OTITIS EXTERNA; of the middle ear, OTITIS MEDIA; of the inner ear, LABYRINTHITIS.
Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.
Conditions caused by abnormal CILIA movement in the body, usually causing KARTAGENER SYNDROME, chronic respiratory disorders, chronic SINUSITIS, and chronic OTITIS. Abnormal ciliary beating is likely due to defects in any of the 200 plus ciliary proteins, such as missing motor enzyme DYNEIN arms.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
