Active clinical trials for "Otitis Media with Effusion"

There are different kinds of ear tubes that may be inserted into the tympanic membrane to relieve recurrent acute otitis and hearing impairment due to otitis media with effusion. The tubes differ in size, shape and material. No-one knows if there are differences between the different kinds of tubes regarding complications. The investigators' hypothesis is that there is differences between the different kinds of tubes regarding complications. To test the investigators' hypothesis, the investigators are about to conduct a randomized controlled study of four kinds of tubes having two different material and two different shapes.

The aim of this study is to investigate whether the microbiota in the upper respiratory tract (nasopharynx, adenoids and middle ear fluid) of otitis media with effusion (OME) patients is changed after 4 weeks of probiotic product intake. Therefore, bacterial DNA from swabs, fluid and tissue will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the bacterial species present in these samples. Furthermore, the concentration of specific pathogens will be monitored via qPCR.

The purpose of this study is to describe the pharmacokinetics (PK) of EXE844 Sterile Otic Suspension, 0.3% following a single bilateral ototopical dose in pediatric subjects, immediately after bilateral tympanostomy tube surgery.

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.

The study has three objectives: To determine if the device can detect if middle ear fluid is present in children who are scheduled for tube placement (myringotomy) If fluid is present to characterize the fluid as thick or thin Evaluate the safety of the device

Rationale: Bacterial biofilms are defined as an assemblage of bacterial cells enclosed in a self-produced glycocalyx matrix. Adherence on surfaces, and resistance to both antibiotic treatments and host defenses are ones of the major clinical features of bacterial biofilms. Hence, biofilm formations represent a serious clinical problem: they persist in human tissues and play a role in a large number of chronic and resistant infections. It has been estimated that more than 65% of all human bacterial infections involve biofilms. Recently, the investigators have demonstrated the presence of mucosal bacterial biofilms in adenoid tissues removed during routine adenoidectomy. Bacterial biofilms were visualized using Confocal Laser Scanning Microscopy (CLSM) with a technique of double staining showing both the bacterial cells and the glycocalyx matrix. Although this study clearly established that adenoids tissues can harbour mucosal biofilms, the prevalence of 54% the investigators found suggested that some groups of children may contain more biofilm formations than others. In an effort to relate the findings of mucosal biofilm with the clinical presentation, the investigators have designed the present work to compare the prevalence of mucosal biofilms in adenoidectomy specimens in two groups: one group of children with chronic otitis media (COM) with effusion versus another group of children without any COM, having adenoids removed for chronic obstruction.

The aim of this study is to assess in France the impact of Prevenar on the possible evolution of the pneumococcal serotypes distribution and antibiotic resistance in NP samples of children with AOM.

Metalloproteinases (MMPs) constitute a family of endopeptidases that cleaves the extracellular matrix as collagen included in the eardrum. Activity of MMP has been shown in some otitis media with effusion (OME) fluids. These enzymes could be directly linked to the prosnostic of OME as it may damage the eardrum and leads to tympanic atrophy. The main goal of the study is to find out the correlation between activity of MMPs and tympanic atrophy. The investigator will also study if there is any clinical predictive factors in relation to the level of MMPs.

This study will determine if the investigators can use certain tests (eustachian tube function tests and gas exchange tests) to predict whether or not a child who had tubes surgically placed in their eardrum because of middle-ear disease will redevelop the disease again after the tubes quit working.

The investigators asked the question if they can better estimate the middle ear status in OME that help them to decide between early intervention or longer follow up.
