OME was defined as effusion in the middle ear behind an intact eardrum for longer than 3 months. Diagnosis was made on the basis of otomicroscopic findings, pneumatic otoscopy, type B tympanometry and audiometry (in older, cooperative children). Children with no fluid in the middle ear during myringotomy were re-diagnosed as having tympanosclerosis and were excluded from the study. Children with craniofacial abnormalities (Down syndrome, Treacher Collins syndrome, clefts etc.) were excluded from the study as well. Demographic data and symptoms of EER disease were provided by parents, who were specifically asked about hoarseness, recurrent lower respiratory infections (bronchitis, pneumonia) and bronchial asthma in their child.\n\n24 hour monitoring of oropharyngeal pH using the Restech system was performed before surgery. Parents were instructed to record the time their child spent eating, drinking and in a horizontal position directly to the device and manually to the diary. If there was any discrepancy, periods logged in the device were modified according to the diary. A standardized RYAN composite score was calculated automatically using the software supplied. Patients with pathological RYAN composite scores in the vertical (higher than 9.4) and/or horizontal (higher than 6.8) position were classified as having pathological EER. Severe EER was diagnosed when the RYAN composite score in the vertical or horizontal position was higher than 200.\n\nMyringotomy using a microscope was done on the anterior inferior part of the tympanic membrane. The type of middle ear effusion (fluid, mucous) was registered. Middle ear fluid was collected using a special suction device with a collecting bottle, and a ventilation tube was inserted in the tympanic membrane. In the case of bilateral OME, middle ear fluids were collected and analysed separately. The specimen was first standardized. 0.1 ml of 10% citric acid was added, the specimen was centrifuged for 10 minutes and subsequently the original migration reagent was added. Afterwards, the specimen was examined using Peptest, which contains monoclonal antibodies that target pepsin. The result of the Peptest was given as positive (2 lines), negative (1 line) or invalid (no line).\n\nThen, adenoidectomy using a cold instrument was performed. A specimen of adenoids (5x5x5mm) from the area close to the torus tubarius was fixed in formaldehyde and immunohistochemically analysed at the Department of Pathology. Antibody P3635Rb-h (Uscnlife, USA, concentration 1:100) was used as the primary antibody. Antibody N-HistofineSimple Stain MAX PO (Nichirei Biosciences Inc.) was used as the secondary antibody.\n\nStatistical analysis was done using MS Excel.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '7 Years', 'minimumAge': '1 Year', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* children with otitis media with effusion\n* age 1-7 years\n* signing of the informed consent\n\nExclusion Criteria:\n\n\\- children with craniofacial abnormalities (Down syndrome, Treacher Collins syndrome, clefts etc.)'}, 'identificationModule': {'nctId': 'NCT02183961', 'briefTitle': 'Three Methods Used in the Diagnosis of EER in Children With OME', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital Ostrava'}, 'officialTitle': 'Comparison of Three Methods Used in the Diagnosis of Extraesophageal Reflux in Children With Chronic Otitis Media With Effusion', 'orgStudyIdInfo': {'id': 'FNO-ENT-EER Peptest Restech'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Laryngopharyngeal reflux', 'description': 'EER was detected using three methods: oropharyngeal pH was monitored for 24 hours using the Restech system; detection of pepsin in middle ear fluid obtained during myringotomy was done using Peptest, and detection of pepsin in adenoid specimen was done immunohistochemically using antibody P3635Rb-h.', 'interventionNames': ['Other: Restech', 'Other: Peptest', 'Other: Detection of pepsin in adenoid specimen']}], 'interventions': [{'name': 'Restech', 'type': 'OTHER', 'armGroupLabels': ['Laryngopharyngeal reflux']}, {'name': 'Peptest', 'type': 'OTHER', 'armGroupLabels': ['Laryngopharyngeal reflux']}, {'name': 'Detection of pepsin in adenoid specimen', 'type': 'OTHER', 'armGroupLabels': ['Laryngopharyngeal reflux']}]}, 'contactsLocationsModule': {'locations': [{'zip': '708 52', 'city': 'Ostrava', 'state': 'Moravian-Silesian Region', 'country': 'Czechia', 'facility': 'University Hospital Ostrava', 'geoPoint': {'lat': 49.83465, 'lon': 18.28204}}], 'overallOfficials': [{'name': 'Martin Formánek, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University Hospital Ostrava'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital Ostrava', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
