Objective: This study analyzed the associations between measured levels of aquaporin (AQP) mRNAs and clinical manifestations in patients with various types of otitis media (OM).

Methods: AQP1, 2, 3, 4, 5, 6, 8, and 10 mRNA levels were assayed by real-time PCR from 57 patients with chronic otitis media (COM), 24 patients with cholesteatomatous otitis media (choleOM), and 82 patients with otitis media with effusion (OME). The relationships of these mRNA levels with the presence of bacteria, the type of hearing loss, and clinical manifestations of OM types were evaluated.

Results: All eight AQP mRNAs were expressed in inflammatory tissue, chole matrix, and effusion fluid obtained from all 163 patients with OM. The levels in OME of AQP2, 4, 6, and 10 mRNA; and the levels in choleOM of AQP1, 3, 4, and 10 mRNA were elevated significantly compared to the corresponding levels in COM (p?p?Conclusions: The levels of expression of AQP mRNA are associated with the pathophysiology of OM.  相似文献

Objective

Patients with complications of otitis media present a significant challenge to safe cochlear implantation. We describe our experience of cochlear implantation in patients with chronic ear disease, and propose management principles according to the presenting status of the ear.

Methods

Cochlear implantations were performed as treatment for complications of otitis media in seven patients. They consisted of four patients with adhesive otitis media, two patients with an open cavity after surgery for otitis media and one patient with eosinophilic otitis media.The electrodes were inserted by an approach via the external auditory canal in patients with poor growth of the mastoid antrum or adhesion of the tympanum. For the patients with an open cavity, we created a posterior wall for the external auditory canal and perform the mastoid obliteration. Modified Rambo's technique with blind sac closure of the external auditory canal was performed for the case of eosinophilic otitis media as a single-stage procedure.

Results

The post-operative courses were good. However, a post-operative infection developed in one patient who had previously undergone radiation therapy following surgical excision of a cerebellar tumor.

Conclusion

Transcanal approach is effective in a poorly pneumatized mastoid or severe adhesive otitis media.A decision whether implantation as a single-stage or multiple stages depends on the condition of each cases. But there is a possibility of infection even if we selected a stage operation.  相似文献

Objectives

Audiometric tests provide information about hearing in otitis media with effusion (OME). Questionnaires can supplement this information by supporting clinical history‐taking as well as potentially providing a standardized and comprehensive assessment of the impact of the disease on a child. There are many possible candidate questionnaires. This study aimed to assess the quality and usability of parent / child questionnaires in OME assessment.

Design and main outcome measures

Fifteen, published questionnaires, commonly used in audiological departments (Auditory Behaviour in Everyday Life (ABEL), Children's Auditory Performance Scale (CHAPS), Children's Home Inventory for Listening Difficulties (CHILD), Children's Outcome Worksheets (COW), Evaluation of Children's Listening and Processing Skills (ECLiPS), Early Listening Function (ELF), Fisher's Auditory Problem Checklist (FAPC), Hearing Loss 7 (HL‐7), Listening Inventory for Education‐ Revised (LIFE‐R Student), Listening Inventory for Education UK Individual Hearing Profile (LIFE‐UK IHP), LittlEARS Auditory Questionnaire (LittlEARS), Listening Situations Questionnaire (LSQ), Otitis Media 6 (OM‐6), Quality of Life in Children's Ear Problems (OMQ‐14), Parents’ Evaluation of Aural/Oral Performance of Children (PEACH) were assessed according to the following 8 criteria: conceptual clarity, respondent burden, reliability, validity, normative data, item bias, ceiling/ floor effects, and administrative burden.

Results

ECLiPS, LittlEARS and PEACH scored highest overall based on the assessment criteria established for this study. None of the questionnaires fully satisfied all 8 criteria. Although all questionnaires assessed issues considered to be of at least adequate relevance to OME, the majority had weaknesses with respect to the assessment of psychometric properties, such as item bias, floor/ceiling effects or measurement reliability and validity. Publications reporting on the evaluation of reliability, validity, normative data, item bias and ceiling/floor effects were not available for most of the questionnaires.

Conclusions

This formal evaluation of questionnaires, currently available to clinicians, highlights three questionnaires as potentially offering a useful adjunct in the assessment of OME in clinical or research settings. These were the ECLiPS, which is suitable for children aged 6 years and older, and either the LittlEARS or the PEACH for younger children. The latter two are narrowly focused on hearing, whereas ECLiPS has a broader focus on listening, language and social difficulties.  相似文献

Objective: This study makes an analysis of the effect of Botulinum toxin type A on otitis media with effusion in rats.

Method: As part of the study, 24 male Wistar Albino rats were divided into three groups: Group 1: Botulinum toxin Type A and Histam?ne (intratympanic 0.2?ml?=?20 unit BTA); Group 2: Saline and Histamine (intratympanic 0.2?ml 0.9%); Group 3: Histamine (intratympanic 0.2?ml). Histamine (intratympanic 0.2?ml) was administered into the right ear for all groups. DPOAE and ABR tests were carried out on days 5, 10, 15 and 20 from the beginning of the study.

Results: There was no significant difference between DPOAE and ABR scores of the groups. In each group, the DPOAE scores for the right ear significantly decreased on day 5 when compared to the basal scores. In each group, there was no significant difference between days 5, 10 and 15 for the right ear.

Conclusions: Botulinum toxin type A blocked the secretion of glands in the middle ear and showed no effect to prevent the formation of serous otitis. In addition, it was found out that Botulinum toxin did not lead to any morphological change in the cochlea  相似文献

The selection of children with otitis media with effusion for adenoidectomy has been criticized on a number of grounds. In spite of the widespread popularity of the procedure there are few objective guidelines to help the otolaryngologist make a decision which is therfore usually subjective. We present a scientifically derived model using a Generalized Linear Interactive Modelling (GLIM) technique from a population of 122 children who underwent either adenoidectomy or no pharyngeal surgery. The outcome parameter studied was otoscopic clearance in an unoperated ear 1 year after treatment. This was related principally to the operation type (P < 0.001) and to the age at which the operation was performed (P < 0.005). Using a probability of clearance threshold of 50% the model was tested on a prospective population of 166 children and outcome was correctly predicted in over 72%. This model enables the surgeon to determine the probability of clearance of effusion following adenoidectomy in an individual child. At a probability threshold of 50% adenoidectomy would be offered to children with bilateral otitis media with effusion aged between 4.33 and 8.00 years. Over the age of 8 years the probability of clearance occurence spontaneously increases beyond 50%. By careful selection of the probability of clearance thresholds it was possible to produce otoscopic resolution in over 80% of those selected undergo adenoidectomy. The model also enables the otolaryngologist to determine the proportion of children with established disease that require adenoidectomy at his own chosen probability thresholds which will ensure that a more effective resource allocation is achieved.  相似文献

To assess the effect of day-care conditions on the occurrence of middle ear infection, 681 children, aged 3-4 yr, were investigated. The investigation comprised an interview with one of the parents, a case history was taken, and a physical examination including tympanometry. At that time 76% of the children had been in day-care away from their homes and half of these were younger than 6 months old. The two groups of children, those in day-care and those looked after at home, were comparable with respect to sex, housing conditions, parents’ social status and smoking habits. An increased occurrence of otitis media was found among children in day-care Measurements of middle ear pressure revealed a significantly larger number of children with flat curves (secretory otitis) and thus poorer hearing among those in day-care than those at home. Among the children in day-care there was also a significantly larger number with a history of adenoidectomy than among those looked after at home. These differences could not be explained by sex, housing conditions, social status or parents’ smoking habits. It is concluded that the apparently greater occurrence of middle ear infection among children in day-care, compared to those looked after at home is due to an increased risk of contamination from children of their own age.  相似文献

Otitis media (OM) is considered a potentially severe disease due to the risk of complications.ObjectiveTo establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors.MethodThis prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined.Results1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis.ConclusionThe incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.  相似文献

The onset of early otitis media (EOM), in the first few months of life has been reported to predict later chronic otitis media (CSOM), although the prevalence rates are increasing little is known about specific risk factors. In this survey we examined the hypothesis that higher risk factors is associated with the development of OM within 1 year compared to later onset and early onset otitis media (OM) has potential for negative outcome of CSOM. This is a survey of the age at onset of otorrhoea and associated risk factors in children with CSOM, in five sites spread in two sub-urban cities in two states in Nigeria. Questionnaires were administered on the informants followed by examination of the children. EOM was seen in 136/189 (70%) with CSOM, the age range was 1-150 months, mean of 59.25 (SD = 44.55). Of the 85 CSOM subjects with hearing loss, EOM accounted for 49 (57.7%) while 36 (42.4%) was later onset, On multivariate analysis (OR = 0.276, CI = 0.133-0.572, P = 0.001) revealing EOM was significant in the development of hearing loss however there was no correlation with the frequency of attack of otorrhoea (OR = 1.025, CI = 0.88-1.19, P = 0.75). Low socioeconomic status seen in 110/136 EOM (P = 0.000), allergy (P = 0.030) and number of people >10 in household (OR = 4.13, CI = 1.81-9.39, P = 0.001) constituted the significant risk for EOM compared to later onset. Bottlefeeding, adenoiditis/adenoid hypertrophy, indoor cooking and upper respiratory infection were not found to have statistical significance in early onset OM compared to later onset OM. This study found correlation between EOM and hearing loss and identified allergy, low social status and chronic exposure to overcrowding through increased number of children in the household significant risk factors for future research focus. This may help in controlling the prevalence of hearing loss accompanying CSOM.  相似文献

Summary Kampo medicine is a traditional Japanese herbal medicine that is known as Sairei-to and has been used to treat otitis media. This preparation was given orally for 4 weeks to 35 children with secretory otitis media (SOM). Four of 46 ears (8.7%) completely resolved while 32 ears (69.6%) showed a partial improvement without serious adverse reaction. Our findings indicate that Kampo medicine may resolve the inflammation and immune response associated with SOM. Further studies in its mechanism of action are warranted.  相似文献

One hundred and ninety-one children who presented to the author’s clinic with otitis media with effusion (OME) over a 2-year period (1986–1988) have been studied prospectively. Resolution of their OME was considered to have occurred when they had normal findings on pneumatic otoscopy, tympanometry and audiometry on at least two occasions 6 months apart and had subjectively normal hearing in between. The number of operations performed during the course of the disease was used as a surrogate for chronicity. Children with a history of previous aural discharge at presentation were significantly more likely to have chronic OME (P = < 0.02).  相似文献

In this study we evaluated eustachian tube function in patients with chronic otitis media and compared the results with normal subjects. Two different eustachian tube function tests were applied to 60 ears of the chronic otitis media group and 146 ears of the control group. While eustachian tube dysfunction was observed in 71.7% of the chronic suppurative otitis media group, it was only seen in 34.9% of the control group.  相似文献

Pathogenic bacteria have been isolated from middle ear effusions in a number of studies. Our aim was to identify factors which predispose to patients having positive cultures. Over a 1-year period, prospective data were collected on patients admitted for myringotomy. Middle ear effusions were collected at the time of surgery using specially designed traps, and underwent microscopy and culture. Data on local weather parameters were obtained from the Meteorological Office in Edinburgh, UK and compared with the patterns of positive cultures. A higher proportion of cultures were positive in October, November and December and in February and May than in the other months of the year. We were not able to relate these variations to any of the meteorological data, with the possible exception of relative humidity, or to any other variable.  相似文献

Otitis media with effusion (OME) is common among children with cleft palate, and may lead to such long‐term consequences as hearing loss, tympanic membrane retraction, and chronic otitis media (COM). In total, 104 children with cleft lip and/or palate treated for OME at our institution were reviewed. Mean duration of follow‐up was 6.9 years, and mean age at latest follow‐up was 9.6 years. The incidence of COM was 19%, and the incidence of cholesteatoma was 1.9%. Ears showing such long‐term sequelae of OME as hearing loss, tympanic membrane retraction, and chronic otitis media, were noted to have undergone a significantly greater number of ventilation tube insertions than ears not showing these sequalae. Our findings would suggest that a conservative approach to the management of OME in children with cleft palate is more likely to be beneficial in the long term.  相似文献

Otitis media with effusion (OME) is the commonest cause of hearing impairment in young children. The fluctuating nature of the condition makes identification of those with persistent disease difficult without subjecting each child to a period of ‘watchful waiting’. The aim of this study was to determine if the outcome of this observation period could in any way be predicted. The study involved the retrospective analysis of 517 children, aged 3–15 years (mean 5 years and 4 months) in whom the diagnosis of OME had been established. All children had been subjected to an observation period before a decision on surgery was taken. There was a significant correlation between the degree of hearing loss at presentation and after the period of observation. Sex was not a reliable predictor of outcome, but age less than 4 years and presentation in autumn or winter were associated with a poor audiometric outcome. This study identifies a predictive influence on the resolution of OME for these three factors and points the way for future research aimed at identifying the subgroup of children with OME who would benefit from early surgical intervention.  相似文献

ObjectiveConventional treatment for acute otitis media mainly targets bacteria with antibiotics, neglecting to control for mediators of inflammation. Mediators of inflammation, such as leukotrienes, have been identified in patients with acute otitis media (AOM) or subsequent secretory otitis media (SOM). They can cause functional eustachian tube dysfunction or increase mucous in the middle ear, causing persistent SOM following AOM. The objective of the present study was to evaluate whether or not administration of pranlukast, a widely used leukotriene C4, D4, and E4 antagonist, together with antibiotics could inhibit the progression to SOM.MethodsChildren with AOM, who were from two to 12 years old, were randomly divided into two groups as follows: a control group in which 50 patients received antibiotic-based conventional treatment according to guidelines for treating AOM proposed by the Japan Otological Society (version 2006); and a pranlukast group, in which 52 patients were administered pranlukast for up to 28 days as well as given conventional treatment. Cases were regarded as persistent SOM when a tympanogram was type B or C2 four weeks after treatment was initiated.ResultsTwo patients in the pranlukast group and 3 patients in the control group were excluded because they relapsed AOM within 28 days after initial treatment. Therefore, the analysis included 50 and 47 subjects in the pranlukast and control groups, respectively. The percentage of patients diagnosed with persistent SOM (22.0%) was significantly smaller in the pranlukast group compared with the control group (44.7%) (p = 0.018, chi-squared test).ConclusionThe results indicate that combined treatment of AOM with antibiotics and a leukotriene antagonist to control inflammation is useful for preventing progression to persistent SOM.  相似文献
