Active clinical trials for "Ear Diseases"

The proposed research is a non-interventional study made to evaluate different measurements on 1 group of participants, before and after taking a nap, aiming to potentially guide future investigations on nap-modulated tinnitus to better understand this phenomenon. The main hypothesis is that sleep apneas could be correlated with an increase of tinnitus intensity.

This study will determine if exposure to an allergy material (ragweed) or exposure to an allergic-symptom-provoking substance (histamine) and medications typically used to decongest the nose changes the rate of blood-flow in the lining of the middle-ear. Otitis media (the build-up of water-like fluid in the middle-ear airspace) may occur if the blood flow in the lining of the middle-ear is too high and may be prevented if a way could be found to lower the blood flow in persons susceptible to the disease. Middle-ear blood flow is measured indirectly by measuring the change in middle-ear pressure while a person breathes a gas mixture containing nitrous oxide ("laughing gas"). In this study, 4 groups of subjects will be entered and middle-ear pressure in persons breathing a mixture of 50% Oxygen, 50% Nitrous Oxide ("laughing gas")will be measured after exposure to one of four substances (ragweed, histamine,an oral decongestant, a decongestant nasal spray) and a fake medication (placebo) at separate test sessions. All subjects will have one set of 2 x-rays of the middle ears and mastoids. The group exposed to ragweed will require 3 study visits while the other 3 groups will have 2 study visits. From this information middle-ear blood flow will be calculated. This will help determine the relationship between what happens in the nose and what happens in the middle ear.

For diagnosis of external and middle ear diseases, an otoscope is a key instrument to use. A microscope has been used as a reference standard to confirm pathology. An endoscope has been also widely used. Both microscope and endoscope provide an excellent image quality, can record and capture the images, and the images can be visualized with an export system. A digital otoscope is widely available and more affordable. A comparative study of the efficacy of the endoscope and the digital endoscope will be performed.

PneuMum is a randomised controlled trial that aims to find out if pneumococcal vaccination for Australian Indigenous mothers, in the last few months of pregnancy or at delivery, can prevent ear disease in infants. Mothers will receive the 23 valent pneumococcal polysaccharide vaccine (23vPPV) either: a) during the third trimester of pregnancy; b) soon after child birth; or c) seven months after child birth (control group). The adult diphtheria, tetanus and acellular pertussis vaccine (dTPa) will be used as the control vaccine for the birth dose. The study aims to recruit 210 Indigenous women aged 18-39 years who have an uncomplicated pregnancy. Following recruitment, subjects will be randomly assigned to one of the three groups. Each mother and infant will be followed from pregnancy until the baby is seven months of age. Children will receive all of their routinely recommended vaccinations in accordance with the standard vaccination schedule. The primary outcome will be prevalence of ear infection at seven months of age, defined as middle ear effusion or tympanic membrane perforation or acute otitis media. Pneumatic otoscopy, video-otoscopy and tympanometry will be used in the ear examinations. The primary analyses will be a direct comparison of the proportion of infants in the control group who have nasopharyngeal carriage of vaccine type pneumococci at seven months of age compared to infants in each of the other two groups and a similar comparison of the proportion with middle ear disease.

Motor control includes postural control and voluntary movement. For an optimal motor control it is necessary that brain integrates vestibular, visual and somatosensorial inputs properly, in a nonlinear way. Vestibular system, as an afferent organ, encodes head position in relation to gravity and changes in its linear and angular acceleration. As vestibular central system, it plays an essential role in motor control and in orientation and spatial memory as well. When a peripheral vestibular lesion occurs, elaboration, interpretation and processing of inputs are deficient and therefore motor control is altered to a greater or lesser degree. As process progress in time, there is a natural neuroplasticity that facilitates recovery or compensate vestibular function, although sometimes this process is incomplete and requires vestibular reeducation This study aims to assess changes in balance control, orientation and handicap perception in one case group with symptomatic unilateral peripheral vestibular dysfunction, before and after a rehabilitation programme (RV). To compare values obtained at the beginning and at the end of RV to those achieved by control group. Finally, this research aims to analyse evolution of spatial orientation quality in symptomatic and non symptomatic participants.

This study is to aid the development for the use of SENS-218 outside its marketed therapeutic indications. SENS-218 is available in Asia and is marketed as an anti-emetic (Anti-sickness) drug often prescribed after exposure to chemotherapy. Chemotherapy exposure can often induce nausea and/or vomiting. The study only involves the one drug, referred to as SENS-218 in this study. The purpose of the study is to support the development of use of SENS-218 in non-Asian population. The key objective of this study is to identify the pharmacokinetic (PK) parameters of the drug in healthy Caucasian population. The PK refers to what the body does to the body, for example, how quickly the drug is absorbed into the blood stream. The population who are eligible to take part in the study are healthy male and female, non-smoking volunteers, aged between 18 and 50 years, as determined by screening tests at Simbec. Participation in the trial will last for about 3 weeks (from first screening visit to final end of study visit).

Prospectively analyze the use of 3D subtraction CAD/CAM in the operating room environment. Study participants, requiring middle ear surgery and ossicular reconstruction, will be implanted with one of two middle ear implants. The rationale is to complete a pilot study of the technology with a small number of designs. Each implant will be commonly used, in the public domain, and recreated by the CAD/CAM software.

The purpose of this study was to analysis the incidence of ear symptoms, cognitive function decline and emotional disorders in Chinese people who were infected with COVID-19, exploring the impact of COVID-19 on the auditory system, cognitive function and emotional function, and analyzing the changes in functional connectivity of brain network after COVID-19 infection.

We study audiometric parameters including Transient Otoacoustic emissions, pure-tone audiometry for air- and bone-conduction, and spondaic speech recognition thresholds for air- and bone conduction in a pre- and postoperative situation in patients due for surgery for tympanic membrane perforations and otosclerosis. The hypotheses are that the precision of the preoperative assessment may be increased, and our knowledge about the effect on the inner ear by middle ear surgery may be increased.

The study is part of the Post Market Clinical Follow (PMCF) activity. The investigational device is the CE-marked Ponto 3 SuperPower (available on the market since December 2016) already fitted to the subjects, and data is collected retrospectively from clinical routine visits. The study is a retrospective study. Therefore there will be no study visits for treatment or follow-up in the study. Subject inclusion for this clinical investigation will be performed among subjects who has been fitted with the Ponto 3 SuperPower. To have a wide representative selection of subjects, enrollment will be spread over the 4 years since the device was available on the market since December 2016. The endpoints in the study will investigate the improvement of hearing with the Ponto 3 SuperPower. The data will be collected from the subjects in the time period from the clinical routine visit where the Ponto 3 SuperPower where fitted or just prior, and from the clinical routine visit following the fitting, where audiologic fitting follow-up procedures are performed (approximately 3 months).
