    The middle ear status was examined in 142 children aged three to eight years from Sukkertoppen and Kangamiut in Greenland. The investigation is based on social-pediatric and otologic histories and on objective examination using otomicroscopy and tympanometry. Three-fourths of the small children had a previous history of otitis, some with repeated instances. Otomicroscopic findings revealed suppurative, chronic otitis in 6% and sequelae of chronic otitis in 13%. Tympanometry disclosed a reduced middle ear pressure in another 26% of the ears examined. Comparison of children with healthy ears with the groups with affections of the middle ear showed a tendency to an increased risk of otitis in families at a low social stratum, whereas the mode of habitation seemed insignificant. Finally, a large milk intake both in connection with breast-feeding and later in life seemed to reduce the frequency of otitis. The investigation showed that acute otitis and chronic otitis media in particular are more prominent in Greenland than in Denmark. Attention is drawn to the handicap associated with a high incidence of chronic otitis media and the concomitant hearing loss to a population isolated in point of language. The successful achievements of a health information campaign and an active therapeutic program, which has reduced the prevalence of chronic otitis among the Innuit population native to Alaska and Canada, provides the rationale for an increased otologic effort in Greenland.

    To observe and analyze the function and morphology of pharyngeal ostium of the eustachian tubes in secretory otitis media and chronic rhinosinusitis in children under direct vision,in order to provide an objective basis for clinical treatments. Fifty cases of secretory otitis media,50 cases of chronic rhinosinusitis and a control group of 50 cases with hoarseness were examined under video laryngoscope to observe the pharyngeal ostium morphological changes of the eustachian tubes, and their functional statuses were tested by using acoustic impedance instrument. All the data were analyzed by statistical methods. (1) In the secretory otitis group, the abnomal rate of the pharyngeal ostium of the eustachian tubes was 94% while the chronic rhinosinusitis group was 80%,and between them there was no significant differences (P > 0.05). But both of them had significant differences with the control group (P otitis group, the rate of the eustachian tube dysfunction was 70% while the chronic rhinosinusitis group was 26%, and between them there was significant differences (P otitis media and chronic rhinosinusitis in children. Eustachian tube dysfunction played a dominant role in the pathogenesis of secretory otitis media in children rather than the morphological change did compared to the chronic rhinosinusitis in children.

    There are 2 different kinds of chronic otitis media: Otitis media chronica mesotympanalis and otitis media chronica epitympanalis (cholesteatoma). The incidence of chronic otitis media as reported in literature differs in a wide range. The incidence rates vary between 0.45 and 46%. Both, otitis media chronica mesotympanalis and cholesteatoma, lead to eardrum perforation due to lengthy and recurring inflammations. Furthermore, chronic otitis media is characterized by frequently recurring otorrhea and conductive hearing loss. Georg Thieme Verlag KG Stuttgart · New York.

    Objective: To study relationship between Eustachian tube and secretory otitis media and to explore the pathogeny of secretory otitis by three-dimensional reconstruction of Eustachian tube. Methods: Thirty cases of secretory otitis media (male 19, female 11) were selected randomly. Everyone was checked by otoscope and audiometry. Their bilateral Eustachian tubes were scanning by helix CT while making Valsalva's action. All images were passed on to work station to make three-dimensional reconstruction. Results: Four patients were found have Eustachian tube diseases, while most of patients' Eustachian tubes ventilated normally. Conclusions: Three-dimensional reconstruction of Eustachian tube can open out some pathogens of some secretory otitis medias. It will be helpful to diagnosis and therapy of secretory otitis media.

    Full Text Available To investigate the possible role of adenoid mast cells in the etiology of secretory otitis media. Between 2001-2002, 25 patients with chronic adenoitis and chronic secretory otitis media and 25 patients with isolated adenoid hypertrophy were included to the study. Adenoidectomy performed to the all patients under general anesthesia. Adenoidectomy specimens were evaluated under the light microscopy and the number of mast cells were calculated for each patient. The number of mast cells were compared between two groups. The number of mast cells were between 4-84 in the otitis media with effusion and adenoid hypertrophy group (median:52, however it was between 2-63 (median: 23 in the isolated adenoid hypertrophy group. When comparing the two groups using Mann-Withney U test, the number of mast cells found to be significantly higher in the chronic secretory otitis media group (p<0.001.Based on our findings there is a relationship between increased adenoid mast cells and otitis media with effusion and these cells may have a possible role in the etiology of chronic secretory otitis media.

    Primary secretory otitis media (PSOM) is a disease that has been described in the Cavalier King Charles spaniel (CKCS). A large, bulging pars flaccida identified on otoscopic examination confirms the diagnosis. However, in many CKCS with PSOM the pars flaccida is flat, and radiographic imaging is needed to confirm the diagnosis. Current treatment for PSOM includes performing a myringotomy into the caudal-ventral quadrant of the pars tensa with subsequent flushing of the mucus out of the bulla using a video otoscope. Repeat myringotomies and flushing of the middle ear are necessary to keep the middle ear free of mucus. Copyright © 2012 Elsevier Inc. All rights reserved.

    In an attempt to evaluate the feasibility of the tympanometry in detecting the middle ear effusion (MEE) in secretory otitis media (SOM) in childhood, the findings of the computed tomography (CT) were evaluated whether they were compatible with that of tympanometry in 27 cases (51 ears) of SOM. Tympanometry (tympanogram, static compliance measurement and stapedial reflex test), pure tone audiometry and high resolution CT were performed sequentially, and the CT findings were compared with the results of the other tests. The conclusions obtained were summarized as follows. 1. Among the tests performed, tympanogram appeared to be the most reliable measure in detection of MEE. 2. Fifteen ears out of 16 with type B tympanograms and 6 ears out of 15 with type C 2 tympanograms, were diagnosed by CT as having MEE. MEE occupied the entire middile ear space in most ears with type B tympanograms. By contrast, in the ears with type C 2 tympanograms, air containing space of varying size were always observed even in the ears with MEE. (author)

    Otitis media (OM) is a common illness in young children. OM has historically been associated with frequent and severe complications. Nowadays it is usually a mild condition that often resolves without treatment. For most children, progression to tympanic membrane perforation and chronic suppurative OM is unusual (low-risk populations); this has led to reevaluation of many interventions that were used routinely in the past. Evidence from a large number of randomized controlled trials can help when discussing treatment options with families. Indigenous children in the United States, Canada, Northern Europe, Australia, and New Zealand experience more OM than other children. In some places, Indigenous children continue to suffer from the most severe forms of the disease. Communities with more than 4% of the children affected by chronic tympanic membrane perforation have a major public health problem (high-risk populations). Higher rates of invasive pneumococcal disease, pneumonia, and chronic suppurative lung disease (including bronchiectasis) are also seen. These children will often benefit from effective treatment of persistent (or recurrent) bacterial infection.

    The Chronic Otitis Media Questionnaire 12 was developed initially in the UK to assess patient-reported health-related quality of life associated with chronic otitis media. This study aimed to determine whether this tool is applicable to the Russian population, which has a materially different healthcare system. A total of 108 patients with different forms of chronic otitis media completed the Russian Chronic Otitis Media Questionnaire 12. The average Russian Chronic Otitis Media Questionnaire 12 score was 19.4 (standard deviation = 8.3). The internal consistency of the Russian Chronic Otitis Media Questionnaire 12 was high, with a Cronbach's alpha value of 0.860. The Russian version of the Chronic Otitis Media Questionnaire 12 was found to be a reliable tool for the assessment of health-related quality of life in patients with chronic otitis media. This sets the scene for international collaboration, using this tool to assess the effectiveness of surgical treatments even amongst countries with different healthcare systems.

    Adenoid hypertrophy and chronic adenoiditis are associated with an increased incidence of chronic otitis media. This study intends to determine the relationship between chronic otitis media and dynamic ciliary beat frequency in children undergoing adenoidectomy. Prospective, controlled study. Pediatric tertiary care hospital. Children undergoing adenoidectomy were enrolled. Patients were stratified according to their indication for surgery, including adenotonsillar hypertrophy with obstructive sleep apnea, chronic otitis media with effusion, or recurrent episodes of acute otitis media. Adenoids were harvested using the curette. Tissue was sectioned and allowed to equilibrate in basal media for 24 hours. Cilia-bearing tissue was then stimulated using isoproterenol or methacholine. Ciliary beat frequency was serially reordered and analyzed using the Sisson-Ammons Video Analysis software program. Baseline ciliary beat frequency was similar in all groups (N = 47, total). Using isoproterenol, children with chronic otitis media with effusion demonstrated a blunted dynamic ciliary response at 2 and 3 hours relative to control (P = .0176 and P = .0282). Methacholine-stimulated ciliary beat frequency was not different between each group. At 2 and 3 hours following isoproterenol stimulation, there was a significant blunting of dynamic ciliary beat frequency in children with chronic otitis media with effusion. This ciliary dysfunction may provide a physiological explanation related to chronic adenoiditis in children with chronic otitis media.

    In a double-blind, randomized trial of 553 infants and children who had otitis media with effusion ("secretory" otitis media), we compared the efficacy of a four-week course of an oral decongestant-antihistamine combination (pseudoephedrine hydrochloride, 4 mg per kilogram of body weight per day, and chlorpheniramine maleate, 0.35 mg per kilogram per day) with that of placebo. Among patients with initially unilateral disease, resolution of middle-ear effusion occurred at four weeks in 38 per cent of those treated with placebo and 34 per cent of those treated with drug (P = 0.74). Among patients with initially bilateral disease the corresponding proportions were 19 and 21 per cent, respectively (P = 0.67). Side effects were reported more often among drug-treated than placebo-treated patients. Decongestant-antihistamine combinations do not appear to be indicated for the treatment of otitis media with effusion in infants and children.

    Full Text Available This study presents the treatment of 68 children with secretory otitis media. Children underwent adenoid vegetations, nasal speech, conductive hearing loss, ventilation disturbance in Eustachian tube. In all children adenoidectomy was indicated.38 boys and 30 girls at the age of 3-17 were divided in two main groups: * 29 children without hypertrophic (enlarged adenoids, * 39 children with enlarged (hypertrophic adenoids.The surgical treatment included insertion of ventilation tubes and adenoidectomy where there where hypertrophic adenoids.Clinical material was analyzed according to hearing threshold, hearing level, middle ear condition estimated by pure tone audiometry and tympanometry before and after treatment. Data concerning both groups were compared.The results indicated that adenoidectomy combined with the ventilation tubes facilitates secretory otitis media heeling as well as decrease of hearing impairments. That enables prompt restoration of the hearing function as an important precondition for development of the language, social, emotional and academic development of children.

    1983-01-01

    Chronic suppurative otitis media (COM) is reported to cause elevation of bone-conduction thresholds either by damage to cochlear sensorineural structures or by alteration in the mechanics of sound transmission in the ear. A retrospective study was made of the medical records of 87 patients with unilateral uncomplicated COM to document that abnormality in bone conduction does exist. In a separate study the cochlear pathology in 12 pairs of temporal bones with unilateral COM was studied by light microscopy. Infected ears showed higher than normal mean bone-conduction thresholds by amounts ranging from 1 dB at 500 Hz to 9.5 dB at 4,000 Hz. The temporal bones showed no greater loss of specialized sensorineural structures in infected ears than in normal control ears. Because there is no evidence that COM caused destruction of hair cells or cochlear neurons, alteration in the mechanics of sound transmission becomes a more plausible explanation for the hearing losses.

    Full Text Available Francesco Di Pierro,1 Daniele Di Pasquale,2 Maurizio Di Cicco2 1Velleja Research, Milan, Italy; 2ORL Department, Ospedale Maggiore Policlinico Ca’ Grande IRCCS, Milan, Italy Abstract: Secretory otitis media (SOM remains a common disease among children. Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM, is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®. After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

    To compare the differential findings of tuberculous otitis media(TOM) with those of chronic sup purative otitis media with or without cholesteatoma, as seen on high resolution temporal bone CT. We retrospectively reviewed 14 cases of TOM, 30 cases of chronic suppurative otitis media(CSOM), and 30 cases of chronic otitis media with cholesteatoma(Chole). All had been pathologically confirmed. We evaluated the preservation of mastoid cells without sclerotic change, the location and extension of soft tissue to the external auditary canal, and erosion of ossicles, the tegmen tympani, scutum, bony labyrinth, facial nerve canal and sigmoid sinus, and the presence of intracranial complications. Soft tissue in the mastoid antrum was seen in all cases of TOM(100%), 29 cases of CSOM(96.7%), and 26 cases of Chole(86.7%). In contrast, the soft tissue in the entire middle ear cavity was noted in 13 cases of TOM(92.8%), 7 cases of CSOM(23.3%), and 12 cases of Chole(40%). Soft tissue extended to the superior aspect of the external auditory canal in 4 cases of TOM (28.6%) and 5 cases of Chole (16.7%). Mastoid air cells were seen in 9 cases of TOM (64.3%), 4 cases of CSOM (13.3%), and 3 cases of Chole(10%). Ossicular erosion was noted in 6 cases of TOM (42.9%), 12 cases of CSOM (40%), and 26 cases of Chole(86.7%), while in one case of TOM (7.1%), 5 cases of CSOM (16.7%), and 15 cases of Chole(50%) there was erosion of the scutum. In one case of TOM, follow-up CT study after 9 months of antituberculous medication without surgery revealed complete clearing of previously noted soft tissue in the middle ear cavity. Specific CT findings of TOM were not seen, but if there were findings of soft tissue in the entire middle ear cavity, soft tissue extension to the external auditory canal, preservation of mastoid air cells without sclerotic change, and intact scutum, TOM may be differentiated from other chronic otitis media

In contrast, the soft tissue in the entire middle ear cavity was noted in 13 cases of TOM(92.8%), 7 cases of CSOM(23.3%), and 12 cases of Chole(40%). Soft tissue extended to the superior aspect of the external auditory canal in 4 cases of TOM (28.6%) and 5 cases of Chole (16.7%). Mastoid air cells were seen in 9 cases of TOM (64.3%), 4 cases of CSOM (13.3%), and 3 cases of Chole(10%). Ossicular erosion was noted in 6 cases of TOM (42.9%), 12 cases of CSOM (40%), and 26 cases of Chole(86.7%), while in one case of TOM (7.1%), 5 cases of CSOM (16.7%), and 15 cases of Chole(50%) there was erosion of the scutum. In one case of TOM, follow-up CT study after 9 months of antituberculous medication without surgery revealed complete clearing of previously noted soft tissue in the middle ear cavity. Specific CT findings of TOM were not seen, but if there were findings of soft tissue in the entire middle ear cavity, soft tissue extension to the external auditory canal, preservation of mastoid air cells without sclerotic change, and intact scutum, TOM may be differentiated from other chronic otitis media.

    Subtotal petrosectomy is the complete exenteration of all air cell tracts of the temporal bone. The isthmus of the Eustachian tube is obliterated and the external auditory canal is closed. The aim of this study was to describe the use of this technique in the management of certain cases of chronic otitis media. We conducted a retrospective revision of the patients treated in our Institution with this technique for chronic otitis media in a 5-year period (2008-2012). All charts were reviewed and data from the otomicroscopy, audiometry, radiology, surgical findings, postoperative complications and follow-up (including diffusion magnetic resonance imaging, MRI) of a minimum of 24 months were collected. In this period petrosectomy was performed on 28 patients for chronic otitis media. We treated 13 cases as primary cases, while 15 cases were secondary (patients that had already undergone another procedure in that ear). Fifteen cases had no serviceable hearing. Only 1 case had an immediate postoperative complication (infection); during the posterior follow-up, 2 cases had to be reoperated for diffusion restriction in the mastoid area revealed in the MRI 2 years after surgery. A subtotal petrosectomy is rarely performed for the treatment of chronic otitis media. However, it is a technique that we have to keep in mind for the treatment of certain cases where there is recurrence and deep hearing loss, as well as in cases with good cochlear reserve if the disease coexists with other complications.

    Otitis media with effusion and obesity are both common in childhood and might share some immunological alterations. This study aimed to investigate the relationship between chronic otitis media with effusion and childhood overweight or obesity, including the potential effects of adenoid or tonsillar hypertrophy on that relationship. This study included 60 children with chronic otitis media with effusion and 86 healthy children aged from 2 to 10 years. Measures of height and weight were used to calculate the body mass index, weight for height and weight z score. The prevalence of overweight or obesity was higher in children with chronic otitis media with effusion, according to the weight for height percentiles (p = 0.012). However, neither the presence of adenoid or tonsillar hypertrophy nor the degree of adenoid hypertrophy was associated with overweight or obesity. Overweight and obesity might be risk factors for developing chronic otitis media with effusion, or vice versa.

    Cultures obtained from pre-operative middle-ear swabs from patients with chronic otitis media have traditionally been used to guide antibiotic selection. This study investigated changes in the bacterial strains of the middle ear during chronic otitis media surgery. Pre-operative bacterial cultures of otorrhoea, and peri-operative cultures of the granulation tissue in either the middle ear or mastoid cavity, were obtained. Post-operative cultures were selectively obtained when otorrhoea developed after surgery. Bacterial growth was observed in 45.5 per cent of pre-operative cultures, 13.5 per cent of peri-operative cultures and 4.5 per cent of post-operative cultures. Methicillin-resistant Staphylococcus aureus was identified as the most common bacteria in all pre-operative (32.4 per cent), peri-operative (52.4 per cent) and post-operative (71.4 per cent) tests, and the percentage of Methicillin-resistant S aureus increased from the pre- to the post-operative period. The bacterial culture results for post-operative otorrhoea showed low agreement with those for pre-operative or peri-operative culture, and strain re-identification was required.

    Seventy six patients with chronic otitis media were examined by CT. Using 3 dried skulls, the epitympanum was impacted with a piece of paraffin containing of 2 % iodine, and studied with CT-scan (Toshiba 60A-30) to clarify whether or not the paraffin could produce a soft tissue density on CT which was similar to that of cholesteatoma in the middle ear. The results showed that computed tomography was excellent in demonstrating a soft tissue mass in the middle ear with inflammatory disease. When the middle ear infection with granulation tissue or cholesteatoma existed, the resulting soft tissue mass was indistinguishable. CT scanning was useful for accurate determination of location of bone destruction in the middle ear as well as of the ossicles. (author)

    Full Text Available BACKGROUND Chronic suppurative otitis media is one among the commonest ENT disease seen in day-to-day practice. It is seen mainly among low socioeconomic class. MATERIALS AND METHODS The present study was conducted in the Department of ENT, Shadan Institute of Medical Sciences. Fifty patients with CSOM of all age groups and both sexes attending the Outpatient Department of ENT were selected randomly for the study. RESULTS From our study, we found mainly children of age group 10-11 years commonly affected. They belong to poor socioeconomic background. Pseudomonas aeruginosa is the most common organism isolated in the present study. Ciprofloxacin was found to be the most sensitive antibiotic to Pseudomonas aeruginosa. CONCLUSION We noticed that drug resistance is on the rise due to misuse of antibiotics, over-the-counter treatment, inadequate period of therapy and less awareness among public regarding drug resistance. Constant monitoring of antibiotic sensitivity is needed to prevent drug resistance in CSOM.

    The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media.

    The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome plays an important role in the pathogenesis of middle ear diseases. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for cholesteatoma and chronic otitis media. NLRP3 inflammasome is a critical molecule mediating interleukin (IL)-1β responses. However, the expression of NLRP3 in the pathogenesis of cholesteatoma and chronic otitis media has not been fully examined. This study sought to assess the expression of NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in middle ear tissues in patients with cholesteatoma or chronic otitis media. Middle ear tissue samples were obtained from patients with cholesteatoma or chronic otitis media. Control middle ear samples were collected during cochlear implant surgery of patients without middle ear inflammation. The expression of NLRP3, ASC, and caspase-1 were examined by reverse transcription polymerase chain reaction (RT-PCR) assay and immunohistochemical study. The levels of mRNA of NLRP3, ASC, and caspase-1 were significantly elevated in cholesteatoma and chronic otitis media as compared with that of normal controls. The proteins of NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells in cholesteatoma and chronic otitis media.

    To evaluate the histopathologic changes of dark, transitional, and hair cells of the vestibular system in human temporal bones from patients with chronic otitis media. Comparative human temporal bone study. Otopathology laboratory. To compare the density of vestibular dark, transitional, and hair cells in temporal bones with and without chronic otitis media, we used differential interference contrast microscopy. In the chronic otitis media group (as compared with the age-matched control group), the density of type I and type II hair cells was significantly decreased in the lateral semicircular canal, saccule, and utricle (P otitis media group in the posterior semicircular canal (P = .005), but that of type II cells was not (P = .168). The mean number of dark cells was significantly decreased in the chronic otitis media group in the lateral semicircular canal (P = .014) and in the posterior semicircular canal (P = .002). We observed no statistically significant difference in the density of transitional cells between the 2 groups (P > .1). The findings of our study suggest that the decrease in the number of vestibular sensory cells and dark cells could be the cause of the clinical symptoms of imbalance of some patients with chronic otitis media. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Full Text Available BACKGROUND Chronic Suppurative Otitis Media (CSOM refers to a chronic inflammatory condition of the middle ear and mastoid cavity. There is acute inflammation of middle ear leading to irritation and then inflammation of the mucosa producing oedema. Breakdown of the epithelium causes ulceration subsequent infection and formation of granuloma/granulation tissue. Granuloma formation leads to the development of polyps in middle ear. Factors influencing development of complications are, age, low socio-economic status, virulence of organism, immune compromised host, previous surgeries, fractures, fistulas, cholesteatoma. The complications developed spread through various modes like direct bone erosion, thrombophlebitis, preformed pathways, congenital bony defects, sutures of skull that remains patent, old fractures-heal by fibrosis, defects caused by surgery, oval and round windows, infection from labyrinth. The extracranial complications which can be encountered in chronic suppurative otitis media are, acute mastoiditis, petrositis, facial nerve palsy, labyrinthitis and discharging sinuses. MATERIALS AND METHODS Sample size for the present study was fifty four. This study was done in the Department of ENT, Travancore Medical College, Kollam. This study was done from January 2015 To January 2016. Detailed clinical history was taken and the clinical examination was conducted. The extracranial complications were noted and reported. RESULTS In the present study, maximum number of cases belonged male sex which was thirty eight cases. Sixteen cases belonged to female sex. Maximum number of cases which amounted to forty one in number belonged to age group zero to twenty years, followed by age group twenty to forty years which amounted to eleven cases, followed by age group forty to sixty which amounted to two cases. No cases were reported in age group more than sixty years in our study. Based on socioeconomic data, maximum number of cases belonged to low

    The aim of this study was to profile and compare the middle ear microbiomes of human subjects with and without chronic otitis media. Prospective multicenter cohort study. All consecutive patients undergoing tympanoplasty surgery for chronic otitis media or ear surgery for conditions other than otitis media were recruited. Sterile swab samples were collected from the middle ear mucosa during surgery. The variable region 4 of the 16S rRNA gene in each sample were amplified using region-specific primers adapted for the Illumina MiSeq sequencer (Illumina, CA, USA)). The sequences were subjected to local blast and classified using Metagenome@KIN (World Fusion, Tokyo, Japan). In total, 155 participants were recruited from seven medical centers. Of these, 88 and 67 had chronic otitis media and normal middle ears, respectively. The most abundant bacterial phyla on the mucosal surfaces of the normal middle ears were Proteobacteria, followed by Actinobacteria, Firmicutes, and Bacteroidetes. The children and adults with normal middle ears differed significantly in terms of middle ear microbiomes. Subjects with chronic otitis media without active inflammation (dry ear) had similar middle ear microbiomes as the normal middle ears group. Subjects with chronic otitis media with active inflammation (wet ear) had a lower prevalence of Proteobacteria and a higher prevalence of Firmicutes than the normal middle ears. The human middle ear is inhabited by more diverse microbial communities than was previously thought. Alteration of the middle ear microbiome may contribute to the pathogenesis of chronic otitis media with active inflammation. 2b.

    The Eustachian tube (ET) is responsible for the ventilation, protection, and cleaning of the middle ear. ET dysfunction plays an important role in the pathogenesis of otitis media cases, and thus the treatment and prognosis of these cases is extremely dependent on adequate ET function, which can ultimately affect the success rate of middle ear reconstruction practices. Data research on the ET’s ventilation function is needed to ensure the success of therapy and surgery treatments in the case of Chronic Suppurative Otitis Media (CSOM) patients. This study aims to investigate ET ventilation functioning in benign type CSOM and non-otitis media subjects and to develop another modality to measure ET ventilation functioning in patients with intact and perforated tympanic membranes. A comparative cross-sectional study of 36 benign type CSOM patients and 80 non-otitis media subjects will be conducted using sonotubometry and the rated parameter measurements of ET opening frequency, amplitude and ET opening duration. Malfunctioning ventilation of the ET is more common among benign type CSOM subjects (47%) than among non-otitis media subjects (18.75%). There is a significant difference (p = 0.002) between the ET ventilation functioning of benign type CSOM subjects and non-otitis media subjects—benign type CSOM subjects have rates of malfunctioning ET ventilation that are 3.88 times higher than those of non-otitis media subjects. Patients with benign type CSOM are more likely to experience malfunctioning ET ventilation than are non-otitis media subjects.

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (pmedia in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.

    To assess the frequency of bacterial agents in chronic suppurative otitis media and the antibiotic susceptibility patterns of isolates among patients. A total of 185 patients clinically diagnosed with chronic suppurative otitis media were interviewed and middle-ear effusion samples were collected using sterile swabs. All bacterial isolates were identified by conventional microbiological methods. Antibiotic susceptibility patterns of the isolates were determined by Kirby-Bauer disc diffusion. Staphylococci spp. (64.9 per cent) were the most prevalent bacteria isolated, followed by Klebsiella spp. (12.9 per cent) and Pseudomonas aeruginosa (10.3 per cent). The most effective antibiotic for treatment of bacterial chronic suppurative otitis media was ciprofloxacin. Statistical analysis showed no significant difference in bacterial infestations among chronic suppurative otitis media patients and the antimicrobial susceptibility patterns of the bacterial isolates based on gender and age (p > 0.05). Our findings highlight the importance of a continuous and periodic evaluation of the bacteriological profile and antibiotic susceptibility patterns in chronic suppurative otitis media patients for efficacious treatment of the infection.

    Full Text Available Introduction: Chronic otitis media (COM, a persistent and durable inflammation and infection of the middle ear, is a common disorder. Alterations in the contralateral ear in sufferers have been observed in recent years. Because only a few studies have been reported in this area, we performed this study in order to assess alterations in the contralateral ear of patients with COM.   Materials and Methods: Cross-sectional and descriptive methods were used in 100 patients with COM who were selected for surgical treatment and admitted to hospital. An information form was completed for all patients including demographic data, medical history of otoscopy and paraclinical examinations such as pure tone audiometry (PTA, tympanometry, Schuller radiography, and high resolution computed tomography (HRCT. All data were processed using SPSS (version 18 software and descriptive statistical tests.   Results: According to otoscopy, PTA, tympanometry and graphical analysis, 60% of patients experienced disorders of the contralateral ear. Otoscopy analysis showed 54% of patients had a disorder of the contralateral ear, with the most common disorder being perforation of the ear drum. PTA showed a 48% incidence of contralateral ear problems (85% conductive hearing impairment; 12.5% sensorineural hearing impairment; 1.2% mixed. A total of 73.2% of patients with conductive hearing loss had a problem across all frequencies, while half of the patients with sensorineural hearing impairment had problems at frequencies greater than 1000 Hz. According to tympanometry, 38% of patients had problem in the contralateral ear. HRCT and Schuller graphical analyses indicated 31.5% and 36% occurrence of contralateral ear disorders, respectively.   Conclusion:  More than 50% of patients with COM in one ear have a chance of also presenting with the disease in the other ear. Outcomes of this study and previous studies have shown that COM should not be perceived as a disease limited

    Full Text Available ntroduction: Chronic otitis media (COM is regarded as one of the disabling diseases which have a great influence on the quality of life. Because of the surgical approach of cholesteatoma, timely diagnosis is very important in management of patients with COM. The purpose of this study was to assess the frequency of cholesteatoma in patients with COM, demographic factors and disease related factors. Materials and Methods: In this retrospective study, medical records of 100 patients with COM who had surgery since 2005 to 2009 in Imam Reza Hospital were selected. Patients’ age, gender, duration of COM, clinical manifestations, location of perforation of tympanic membrane and presence or absence of cholesteatoma were analyzed by SPSS statistical software and some tables and graphs were planned. Results: patients   included 70 males and 30 females with an average age of 23.08 ± 11.35. Mean of COM duration was 8.04 ± 7.14 years. The most common manifestations of the disease were otorrhea (92% and hearing loss (80%. The most frequent type of tympanic perforation was total perforation. Frequency of cholesteatoma was 42% and it was more common in males than females (42.9% and 40%. Presence of choleasteatoma was related to gender, age, location of tympanic perforation, presence of otorrhea and hearing loss. Conclusion: Prevalence of cholesteatoma in patients  with COM  in  Mashhad  is more than  other  cites of Iran and  also other  countries, but it is less than prevalence of non cholesteatomatos COM. It is very important to pay more attention to patients with COM who are evaluated about presence of cholesteatoma, specially those with otorrhea, hearing loss, total perforation of tympanic membrane or male gender.

    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 attributed to prevent resolution of chronic otitis media. This research aims to determine the association between the microbiological flora of the nasopharynx with that of the middle ear in patients suffering from chronic (active) mucosal otitis media. Methods: Our study is a hospital-based cross-sectional survey. It was conducted from December 2015 to February 2017 at the Department of ENT, Combined Military Hospital, Abbottabad. Ear and nasopharyngeal swabs were obtained from 65 patients of chronic active mucosal otitis media and sent for microbiological analysis. Microbiological culture and sensitivity test was performed to identify the microbial spectrum of each specimen. Performa bearing the result of otoscopy, aspirate and swabs were completed for middle ear and the nasopharyngeal culture with reference to each patient. Descriptive statistics and Pearson's chi square analysis were performed using SPSS-22. Results: Staphylococcus aureus and Pseudomonas aeruginosa are foremost micro-organisms found in otorrhea culture isolated from patients of chronic active mucosal otitis media. Majority of the cultures from nasopharynx of these patients did not reveal any growth after incubation for 48 hours. Conclusion: A statistically insignificant association exists between the microbiological spectrum of the middle ear and the nasopharynx of patients suffering from chronic active mucosal otitis media. Micro organisms' exposure from a perforated tympanic membrane remains leading cause of persistent otorrhea, rather than ascending infection through the Eustachian tube. (author)

    Full Text Available Chronic suppurative otitis media is among the most frequent illnesses treated in ENT wards. To establish the diagnosis, otomicroscopy alone usually suffice. Assessing the sense of hearing, often the sense of balance, too, is mandatory. Assessment of hearing will show the extent of conductive and sensorineural hearing loss. Apart from this, sometimes, when the finding is not obvious, it is necessary to conduct audiological investigation in more detail in order to establish whether the diagnosis of chronic suppurative otitis media is correct. Existence and extent of conductive hearing loss or confIrmation of tympanic membrane perforation by tympanometry can help a great deal. Also, some new results about the site of perforation and the middle ear volume influence on conductive hearing loss may help have a better insight into chronic suppurative otitis media. Assessing the sense of balance may show dysfunctions with not yet necessarily permanent damage: perilymphatic fistula and benign paroxysmal positional vertigo (BPPV. Unilateral or bilateral damage may be diagnosed with appropriate tests of vestibuloocular reflex (VOR: spontaneous nystagmus, head impulse test, head shaking test. These bedside tests do not require bulky, expensive equipment for stimulus delivery or special equipment for recording nystagmus. In addition, their significance is their ability to provide enough information without performing caloric testing which is contraindicated in chronic suppurative otitis media.

    BACKGROUND:: Children in the developing parts of the world have a high prevalence of chronic suppurative otitis media (CSOM). It is estimated that 65 to 330 million people worldwide have CSOM, yet very little is known about the natural course of the disease. The Inuit population of the Arctic......-based cohort of 591 children originally examined during 1993 to 1994 at 3 to 8 years of age. Follow-up was attempted among 348 individuals still living in the areas. Video otoscopy and tympanometry were used. Data on otologic disease, ear surgery, and antibiotic use for otitis media were collected from medical...... of spontaneous healing was not influenced by the age at which CSOM was diagnosed in the initial study. Thirty-nine individuals (17%) had CSOM in either the initial study or at follow-up. Of these, 2 had never received antibiotic treatment for otitis media, and 15 had been treated less than 3 times.

    BACKGROUND Gradenigo's syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo's syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo's syndrome presenting with meningitis on a background of chronic suppurative otitis media (CSOM) and petrous apicitis (apical petrositis). CASE REPORT A 58-year-old male African American presented with headaches and confusion. Magnetic resonance imaging (MRI) of the head showed petrous apicitis with mastoiditis and abscess formation in the cerebellomedullary cistern (cisterna magna). The case was complicated by the development of palsy of the fourth (trochlear) cranial nerve, fifth (trigeminal) cranial nerve, and sixth (abducens) cranial nerve, with radiological changes indicating infection involving the seventh (facial) cranial nerve, and eighth (vestibulocochlear) cranial nerve. Cerebrospinal fluid (CSF) culture results were positive for Klebsiella pneumoniae, sensitive to ceftriaxone. The patient improved with surgery that included a left mastoidectomy and debridement of the petrous apex, followed by a ten-week course of antibiotics. Follow-up MRI showed resolution of the infection. CONCLUSIONS This report is of an atypical case of Gradenigo's syndrome. It is important to recognize that the classical triad of Gradenigo's syndrome, suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve, may also involve chronic suppurative otitis media (CSOM), which may lead to involvement of other cranial nerves, petrous apicitis (apical petrositis), and bacterial meningitis.

    Objective: To explore the value of' HRCT in the diagnosis of chronic otitis and mastoiditis. Method: Thirty-five patients with chronic otitis and mastoiditis received high resolution CT scan (HRCT). Results: (1) In cases of cholesteatoma, the mass was seen in tympanic sinus and the tympanum area; where the positive rate of' drum damage was 92% and most of the damage of substantia ossea involved the adjacent tissue. The positive rate of the disappearance, damage and cirrhosis of otosteon was 94% in patients with granuloma-type mastoiditis. The damage of eardrum wall was revealed in 15% cases of granuloma-type, in which ossicular chain was revealed wrapped with granulation tissue. The damage of ossicular chain was 23% in cases of granuloma-type. In cases of simple type, the damage of eardrum wall and the substantia ossea adjacent the ossicular chain was rare, and there was no mass. Conclusions: The HRCT is useful in the diagnosis of chronic mastoiditis. (authors)

    We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups. Although type I tympanoplasty was performed most frequently in all age groups, it was performed significantly less often in the elderly group (pgroup (page groups (pgroups. The mean patch effect was significantly better in the younger group than in middle or elderly groups (p<0.05). The less pneumatized mastoid and ossicular diseases in elderly patients with chronic perforated otitis media suggest that they had longer lasting and more severe childhood middle ear pathologies than did younger patients.

    Chronic otitis media (COM), affecting all over the world and in a wide range of age groups in Turkey, is an important cause of ear discharge and hearing loss. The main clinical manifestations are tympanic membrane perforation, ear, nose and throat problems. On the tympanic membrane perforation becomes persistent and cholesteatoma development, there are a lot of opinions today. Especially in the pathology associated with otitis media with effusion eustachian tube, it is known that COM and cholesteatoma develop. In our study, we interpreted 210 patients' temporal computed tomography (CT). Seventy of these 210 patients had otitis media with cholesteatoma, 70 patients had only otitis media without cholesteatoma, and 70 patients had no otitis media. The eustachian tubes were evaluated using temporal CT multiplanar reconstruction method. Angles with the horizontal plane of the eustachian tube and Reid and tubotympanic angles were measured. The angles between eustachian tube and horizontally oriented Reid plane of the patients with cholesteatoma were found to be significantly lower than the patients with otitis media without cholesteatoma and the patients with no history of otitis media. For the tubotympanic angle, no statistically significant differences were observed between the groups. These results suggest that the decrease in the angle with the horizontal plane of Reid in the eustachian tube in adults may play a significant role in the etiology of cholesteatoma.

    Toll-like receptors (TLRs) have a prominent role in inducing innate immune response. It has been suggested that regulation of TLRs is involved in the pathogenesis of chronic otitis media. TLR 2 and TLR 4 polymorphisms were connected with susceptibility to acute otitis and chronic otitis with effusion. The objective of this study was to establish expression of TLR 2 and 4 on middle ear mucosa in different types of chronic suppurative otitis media (CSOM), and the influence of gene polymorphisms TLR 2 Arg753Gln and TLR 4 Thr399Ile and Asp299Gly to susceptibility to CSOM. Middle ear mucosa and full blood samples were obtained from 85 patients with chronic suppurative otitis media with and without cholesteatoma. Control group for mucosal TLR expression consisted of 71 samples of middle ear mucosa taken from patients with otosclerosis, and control group for DNA polymorphism consisted of 100 full blood samples in healthy subjects. DNA polymorphism detection was done with restriction fragment length polymorphism in RT PCR. Expression of TLR 2 and 4 was determined with immunohistochemical staining. TLR 2 and TLR 4 expression on the middle ear mucosa was not influenced by age of the patients with chronic otitis media. Incidence of TLR 2 Arg753Gln polymorphism was significantly higher in patients with chronic otitis media, compared to control group. Significant association between TLR 2 Arg753Gln polymorphism and different types of mucosal changes in patients with chronic otitis media was established. TLR 2 and 4 expression on experimental group mucosa was significantly different compared to control group, where there was no expression (p=0.000). Strong dependence of TLR 2 and TLR 4 expression on middle ear mucosa with different mucosal changes and immunohistochemical activity after staining was detected. Certain polymorphisms in TLR genes could be indicative for susceptibility to chronic otitis media. Expression of TLR 2 and 4 on middle ear mucosa was more dependable on

    Background: The treatment results of symptomatic radiation therapy of the Eustachian tube in chronic otitis media had to be evaluated retrospectively. Patients and Methods: Between 1980 and 1997, 66 patients were referred for therapy. The median age was 58 years. In the clinical presentation, all the patients had a hearing impairment, 35 patients complained of pain, 21 had otorrhea. In their history, 20 patients indicated chronic recurrent infections. The complaints lasted for 4.7 years in the median, primary conservative (adstringentia, antibiotics) and surgical treatment (paracentesis, tympanic tubule, tympanoplastic) did not lead to lasting cure. In 40 of 66 patients, finally radiation therapy was done of both Eustachian tubes. With opposed fields and cobalt-60 photons a total dose of 6 Gy at single doses of 1 Gy, three times a week, was applied. Under the causes for exclusion of radiation therapy were non-acceptance of the patients (nine), prior radiation therapies (six) or spontaneous improvement after initial presentation in our department. The treatment results were evaluated by interviews of the patients and regular otorhinolaryngological examinations. Results: There were no side effects noticed. 28 of 40 (70%) patients reported a significant improvement that could be verified by objective otorhinolaryngological examinations. In the group of 26 nonirradiated patients, 22 could be interviewed indicating in 16 cases (72%) that the complaints were unchanged and chronic otitis media was lasting. In a subgroup analysis concerning the duration of otitis media radiation therapy proved more effective in an acute and subacute stadium of disease of up to 5 years duration, while the patients resistant to radiation therapy were entirely in a chronic stage of disease exceeding 5 years duration.

    Health care systems and physicians need to conform to budgets and streamline resources to provide cost-effective quality care. Although endoscopic tympanoplasty (ET) has been performed for decades, no studies on the cost-effectiveness of ET and microscopic tympanoplasty (MT) for treating chronic otitis media have been published. The present study aimed to compare the cost-effectiveness of ET and MT for treating chronic otitis media. This study was performed using a Cohort-style Markov decision-tree economic model with a 30-year time horizon. The economic perspective was that of a third-party payer (Taiwan National Health Insurance System). Two treatment strategies were compared, namely ET and MT. The primary outcome was the incremental cost per quality-adjusted life year (QALY). Probabilities were obtained from meta-analyses. Costs were obtained from the published literature and Taiwan National Health Insurance System database. Multiple sensitivity analyses were performed to account for data uncertainty. The reference case revealed that the total cost of ET was $NT 20,901 for 17.08 QALY per patient. By contrast, the total cost of MT was $NT 21,171 for 17.15 QALY per patient. The incremental cost effectiveness ratio for ET versus that of MT was $NT 3703 per QALY. The cost-effectiveness acceptability curve indicated that ET was comparable to MT at a willingness-to-pay threshold of larger than $NT 35,000 per QALY. This cost-effectiveness analysis indicates that ET is comparable to MT for treating chronic otitis media in Taiwan. This result provides the latest information for physicians, the government, and third-party payers to select proper clinical practice. Copyright © 2017. Published by Elsevier Taiwan LLC.

    Computed tomography (CT) of the temporal bone was made in 37 patients aged 2 to 55 years with chronic exudative otitis media (CEOM). In 21 of them the pathology was bilateral. The analysis of 58 CT images has identified CT signs of chronic exudative otitis media. They include partial (17 temporary bones) or complete (38 temporal bones) block of the bone opening of the auditory tube, pneumatic defects of the tympanic cavity (58 temporal bones), pneumatic defects of the mastoid process and antrum (47 temporal bones), pathologic retraction of the tympanic membrane. The examination of the temporal bone detected both CT-signs of CEOM and other causes of hearing disorders in 14 patients (26 temporal bones) with CEOM symptoms and inadequately high hypoacusis. Among these causes were malformation of the auditory ossicula (n=5), malformation of the labynthine window (n=2), malformation of the middle and internal ear (n=4), a wide aqueduct of the vestibule, labyrinthine anomaly of Mondini's type (n=1), cochlear hypoplasia (n=4), stenosis of the internal acoustic meatuses (n=2). Sclerotic fibrous dysplasia was suggested in 2 temporal bones (by CT data). CT was repeated after surgical treatment of 10 patients (14 temporal bones) and visual assessment of tympanostomy results was made.

    The present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p sensitivity (p anxiety (p social functioning (p < 0.001), and mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests.

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq 186 Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 ± 0.5 by patients self-evaluation and by physicians scoring of +0.81 ± 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

    The authors' aim was to investigate whether serum neutrophil to lymphocyte ratio might be used as a predictive biomarker to help differentiate active from inactive chronic otitis media (COM). Two hundred fifty-nine patients having inactive COM received tympanoplasty without mastoidectomy and were identified as Group 1. On the other hand, 254 patients having active COM received tympanoplasty with mastoidectomy and were identified as Group 2. Routine hemogram tests were performed preoperatively for both the groups. By performing a chart review, white blood cell count, red blood cell count, hemoglobin, hematocrit, platelet, and mean platelet volume values were compared between the groups in an age-matched and sex-matched manner. A total of 513 COM patients with age range of 7 to 65 years were included in the study. Two hundred seventy-five patients (53.6%) were male, 238 were (46.4%) female. Preoperatively both serum neutrophil and lymphocyte counts were significantly higher in Group 2 (P = 0.015 and P = 0.004, respectively). However, the neutrophil-to-lymphocyte ratios between the groups were not significantly different (P = 0.511). No statistically significant differences were identified from preoperative neutrophil-to-lymphocyte ratios between patients having active COM and inactive COM. Level NA.

    Full Text Available Otitis media with effusion (OME is the commonest cause of hearing loss in children, yet the underlying genetic pathways and mechanisms involved are incompletely understood. Ventilation of the middle ear with tympanostomy tubes is the commonest surgical procedure in children and the best treatment for chronic OME, but the mechanism by which they work remains uncertain. As hypoxia is a common feature of inflamed microenvironments, moderation of hypoxia may be a significant contributory mechanism. We have investigated the occurrence of hypoxia and hypoxia-inducible factor (HIF mediated responses in Junbo and Jeff mouse mutant models, which develop spontaneous chronic otitis media. We found that Jeff and Junbo mice labeled in vivo with pimonidazole showed cellular hypoxia in inflammatory cells in the bulla lumen, and in Junbo the middle ear mucosa was also hypoxic. The bulla fluid inflammatory cell numbers were greater and the upregulation of inflammatory gene networks were more pronounced in Junbo than Jeff. Hif-1α gene expression was elevated in bulla fluid inflammatory cells, and there was upregulation of its target genes including Vegfa in Junbo and Jeff. We therefore investigated the effects in Junbo of small-molecule inhibitors of VEGFR signaling (PTK787, SU-11248, and BAY 43-9006 and destabilizing HIF by inhibiting its chaperone HSP90 with 17-DMAG. We found that both classes of inhibitor significantly reduced hearing loss and the occurrence of bulla fluid and that VEGFR inhibitors moderated angiogenesis and lymphangiogenesis in the inflamed middle ear mucosa. The effectiveness of HSP90 and VEGFR signaling inhibitors in suppressing OM in the Junbo model implicates HIF-mediated VEGF as playing a pivotal role in OM pathogenesis. Our analysis of the Junbo and Jeff mutants highlights the role of hypoxia and HIF-mediated pathways, and we conclude that targeting molecules in HIF-VEGF signaling pathways has therapeutic potential in the treatment of

    To evaluate the effect of ET diameter on Chronic Otitis Media (COM) pathogenesis. Retrospective. Patients with unilateral COM disease are included in the study. The connection between fibrocartilaginous and osseous segments of the Eustachian Tube (ET) on axial Computed Tomography (CT) images was defined and the diameter of this segment is measured. The measurements were carried out bilaterally and statistically compared. 154 (76 (49%) male, 78 (51%) female patients were diagnosed with unilateral COM and included in the study. The mean diameter of ET was 1947mm (Std. deviation±0.5247) for healthy ears and 1788mm (Std. deviation±0.5306) for diseased ears. The statistical analysis showed a significantly narrow ET diameter in diseased ear side (p<0.01). The dysfunction or anatomical anomalies of ET are correlated with COM. Measuring of the bony diameter of ET during routine Temporal CT examination is recommended for our colleagues. Copyright © 2017 Elsevier Inc. All rights reserved.

    To compare the eustachian tube (ET) angle (ETa) and length (ETl) of ears with and without chronic otitis media (COM), and to determine the relationship between ET anatomy and the development of COM. A retrospective case-control study. The study group comprised 125 patients (age range, 8-79 years; 64 males and 61 females) with 124 normal ears and 126 diseased ears, including ears with chronic suppurative otitis media (CSOM) with central perforation, intratympanic tympanosclerosis (ITTS), cholesteatoma, and a tympanic membrane with retraction pockets (TMRP). ET angle and length were measured using computed tomography employing the multiplanar reconstruction technique. The ETa was significantly more horizontal in diseased versus normal ears of all study groups (P = .030), and there was no group difference in ETl (P = .160). ETl was shorter in CSOM versus ITTS ears and normal ears (P = .007 and P = .003, respectively) and in cholesteatoma versus TMRP ears (P = .014). In the unilateral COM group, there were no significant differences in the ETa or ETl of diseased versus contralateral normal ears (P = .155 and P = .710, respectively). The ETa was significantly more horizontal in childhood-onset diseased versus normal ears (P = .027), and there was no group difference in ETl (P = .732). The ETa (P = .002) and ETl (P < .001) were significantly greater in males than females. A more horizontal ETa and shorter ETl could be contributory (though not significantly) etiological factors in the development of COM. 3b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Measuring the impact on quality of life, especially after the beginning of the treatment, is becoming increasingly important in healthcare. The aim of this study was to translate the Chronic Otitis Media Questionnaire-12 (COMQ-12) into Portuguese language and validate this version in a group of patients with chronic otitis media. The Portuguese version of COMQ-12 was obtained by translation and back translation. Portuguese speaking patients with a history of active chronic otitis media were asked to complete the COMQ-12 Portuguese version. Cronbach's α coefficient was calculated for an estimation of the internal consistency of the questionnaire. A total of 100 patients were included in the study; 49 women and 51 men, with a mean age of 39 years (range 12-77 years, median 40 years). The average COMQ-12 score was 29, out of a maximum score of 60. Cronbach's α result for the Portuguese version of the COMQ-12 was 0.85, indicating a high internal consistency. The participants presented with different forms of chronic otitis media, and almost all domains of the COMQ-12 questionnaire were able to differentiate between patients with healed chronic otitis media and patients with cholesteatoma or wet tympanic membrane perforation. Showing that patients with healed chronic otitis media have a better quality of life, measured by the COMQ-12, is a first step to guarantee the questionnaire's validity. The next step will consist on routinely using the questionnaire in patients undergoing surgery for chronic otitis media in order to evaluate their quality of life after treatment. The COMQ-12 Portuguese version showed high reliability, and may be used as an assessment of quality of life in patients with chronic otitis media.

    Full Text Available Risk factors associated with chronic otitis media (COM and recurrent otitis media (ROM have been investigated in previous studies. The objective of this study was to integrate the findings and determine the possible risk factors for COM/ROM based on our meta-analysis. A comprehensive search of electronic bibliographic databases (PubMed, Embase, CNKI and Wanfang database from 1964 to Dec 2012, as well as a manual search of references of articles, was performed. A total of 2971 articles were searched, and 198 full-text articles were assessed for eligibility; 24 studies were eligible for this meta-analysis. Regarding risk factors for COM/ROM, there were two to nine different studies from which the odds ratios (ORs could be pooled. The presence of allergy or atopy increased the risk of COM/ROM (OR, 1.36; 95% CI, 1.13-1.64; P = 0.001. An upper respiratory tract infection (URTI significantly increased the risk of COM/ROM (OR, 6.59; 95% CI, 3.13-13.89; P<0.00001. Snoring appeared to be a significant risk factor for COM/ROM (OR, 1.96; 95% CI, 1.78-2.16; P<0.00001. A patient history of acute otitis media (AOM/ROM increased the risk of COM/ROM (OR, 11.13; 95% CI, 1.06-116.44; P = 0.04. Passive smoke significantly increased the risk of COM/ROM (OR, 1.39; 95% CI, 1.02-1.89 P = 0.04. Low social status appeared to be a risk factor for COM/ROM (OR, 3.82; 95% CI, 1.11-13.15; P = 0.03. Our meta-analysis identified reliable conclusions that allergy/atopy, URTI, snoring, previous history of AOM/ROM, Second-hand smoke and low social status are important risk factors for COM/ROM. Other unidentified risk factors need to be identified in further studies with critical criteria.

    Middle ear surgery aims to eliminate pathology from the middle ear, improve drainage and ventilation of the postoperative cavity, and reconstruct the tympanic membrane and ossicles. The aim of this work is to define the factors that affect ABG (air-bone gap) and bone conduction in the patients operated on due to chronic otitis media. A prospective analysis of patients operated on due to diseases of the middle ear during 2009-2012 was carried out. The cases of patients operated on for the first time due to chronic otitis media were analyzed. The analysis encompassed patients who had undergone middle ear surgery. The patients were divided into several groups taking into account the abnormalities of the middle ear mucous and damage of the ossicular chain observed during otosurgery. A significant hearing improvement was observed in patients with type 2 tympanoplasty in the course of chronic cholesteatoma otitis media and in patients with simple chronic inflammatory process in whom a PORP was used in the reconstruction. Granulation tissue was an unfavorable factor of hearing improvement following tympanoplasty. A significant improvement of bone conduction was observed in the patients with dry perforation without other lesions in the middle ear. The elimination of granulation lesions was a positive factor for the future improvement of the function of the inner ear. The presence of granuloma-related lesions in the middle ear spaces is likely to impede hearing improvement. Damage to the ossicular chain rules out the possibility of bone conduction improvement after surgery. The prognosis on tube-related simple chronic otitis media after myringoplasty, with the preserved continuity of the ossicular chain, consists of closing the ABG and leads to significant improvement of bone conduction.

    Full Text Available Chronic otitis media is a common disease which can lead to serious complications or even death. Betterment of eustachian tube function is effective on results of operations. The main goal of this study was to determine the effect of eustachian tube function on outcome of graft in tympanoplasty or tympanomastoidectomy for chronic otitis media. We prospectively studied 126 patients who underwent these operations in Amir Alam hospital in 1998. Eustachian tube function, technique of operation, use of silastic, age, sex, presence of cholesteatoma were evaluated in each patient and graft vascularization after 6 to 8 weeks of surgery was considered as successful outcome. Among 126 ears, 59 had good ETF and among those 59 ears 88.1% or 52 had successful outcome. Among 67 patients with poor ETF 46 or 68.7% got successful results. This significant difference shows the role of Eustachian tube function on the result of surgery.

    Chronic otitis media (COM) is a widespread pathological condition that affects up to 2% of the general population. Certain forms of this disease markedly deteriorate the quality of life of the patients which makes them overestimate the severity of harm to their health status and can be a cause of inflated expectations as regards the results of the planned surgical treatment. The linking element between the patient's expectations and the outcomes of the surgical intervention may be the recently developed questionnaires for the evaluation of the health-related quality of life (HRQoL). One of them, the COMQ-12 questionnaire, was devised to estimate the subjective reports by the patients concerning the deterioration of their quality of life attributable to chronic otitis media. The objective of the present study was to characterize the value of the 5-point Russian-language version of COMQ-12 for the evaluation of each of its 12 items concerning various aspects of health based on the personal opinions of the patients suffering from chronic otitis media The study included 108 patients 49 of whom were men and 59 women (45% and 55% respectively) at the age varying from 16 to 84 years. The COMQ-12 scores, according to the reports of individual patients, ranged from 4 to 43 of the 60 ones possible. The average score was 19.4 (SD=8.3). The overall median COMQ-12 score was 20, and the mode scored 14. The Cronbach-alpha index was equal to 0.860. The Russian-language version of the COMQ-12 questionnaire provides a reliable tool for the estimation of the quality of life in the patients presenting with various forms of chronic otitis media.

  17. Secretory diarrhea.

    Diarrhea, defined as loose stools, occurs when the intestine does not complete absorption of electrolytes and water from luminal contents. This can happen when a nonabsorbable, osmotically active substance is ingested ("osmotic diarrhea") or when electrolyte absorption is impaired ("secretory diarrhea"). Most cases of acute and chronic diarrhea are due to the latter mechanism. Secretory diarrhea can result from bacterial toxins, reduced absorptive surface area caused by disease or resection, luminal secretagogues (such as bile acids or laxatives), circulating secretagogues (such as various hormones, drugs, and poisons), and medical problems that compromise regulation of intestinal function. Evaluation of patients with secretory diarrhea must be tailored to find the likely causes of this problem. Specific and nonspecific treatment can be valuable.

    We conducted a prospective, controlled study of patients with chronic otitis media and cholesteatoma (1) to examine the expression of myeloperoxidase (MPO) using immunohistochemical staining techniques and (2) to investigate the relationship between MPO activity and the degree of conductive hearing loss in these patients. Our study population included 51 adults-26 men and 25 women, aged 18 to 58 years (mean: 37.5)-who had been diagnosed with chronic otitis media and cholesteatoma by physical examination and computed tomography (study group). Another 30 patients-13 men and 17 women, aged 18 to 52 years (mean: 32.7)-who had chronic otitis media without cholesteatoma served as the control group. Following audiometric evaluations, all patients underwent appropriate surgery. Postoperatively, cholesteatoma samples were analyzed by immunostaining for MPO positivity as a marker for acute inflammation. We found that MPO activity was present in all 51 study patients (100%) but in only 10 controls (33.3%); the difference was statistically significant (pconductive hearing loss (χ(2) = 13.518; p < 0.001). We encourage further study of all steps in the process of cholesteatoma formation.

    Otitis media (OM) or middle ear inflammation is a spectrum of diseases, including acute otitis media (AOM), otitis media with effusion (OME; 'glue ear') and chronic suppurative otitis media (CSOM). OM is among the most common diseases in young children worldwide. Although OM may resolve spontaneously without complications, it can be associated with hearing loss and life-long sequelae. In developing countries, CSOM is a leading cause of hearing loss. OM can be of bacterial or viral origin; during 'colds', viruses can ascend through the Eustachian tube to the middle ear and pave the way for bacterial otopathogens that reside in the nasopharynx. Diagnosis depends on typical signs and symptoms, such as acute ear pain and bulging of the tympanic membrane (eardrum) for AOM and hearing loss for OME; diagnostic modalities include (pneumatic) otoscopy, tympanometry and audiometry. Symptomatic management of ear pain and fever is the mainstay of AOM treatment, reserving antibiotics for children with severe, persistent or recurrent infections. Management of OME largely consists of watchful waiting, with ventilation (tympanostomy) tubes primarily for children with chronic effusions and hearing loss, developmental delays or learning difficulties. The role of hearing aids to alleviate symptoms of hearing loss in the management of OME needs further study. Insertion of ventilation tubes and adenoidectomy are common operations for recurrent AOM to prevent recurrences, but their effectiveness is still debated. Despite reports of a decline in the incidence of OM over the past decade, attributed to the implementation of clinical guidelines that promote accurate diagnosis and judicious use of antibiotics and to pneumococcal conjugate vaccination, OM continues to be a leading cause for medical consultation, antibiotic prescription and surgery in high-income countries.

    The objective of this study was to analyze the results of endoscopy-assisted ear surgery for the treatment of chronic otitis media with cholesteatoma, adhesion, or retraction pockets.Fifty-one patients who underwent oto-endoscopy-assisted canal wall up tympanomastoid surgery and/or limited anterior atticotomy with tympanoplasty for chronic otitis media with cholesteatoma, adhesion, or retraction pocket from 2006 to 2013 have been included in this study. Eradication of the disease from the middle ear and mastoid air cells was achieved by combination of the oto-microscobic and oto-endoscopic approaches. Second look surgery was performed 18 months later from the initial surgery in selected patients. Age, gender, pre-/postoperative otoscopy findings/audiograms, type of the used prostheses, and follow-up time were obtained from the patient's file. Anatomic integrity rates of the tympanic membrane, the mean gains of air bone gap, on pure-tone audiogram at 4 frequencies and existence of the residual disease were reviewed parameters. Functional evaluation was made in patients with intact tympanic membrane.Of the 51 patients, the ratios of the chronic otitis media with cholesteatoma and isolated adhesive otitis or retraction pocket cases were 74.5% (38/51) and 25.5% (13/51), respectively. Ossicular chain reconstruction was made with PORP in 27 patients and TORP in 20 patients, whereas the ossicular chain was intact in 4 patients. Anatomic integrity rates of the tympanic membrane were 90.2% (46/51). The overall (n = 46) pre-/postoperative mean ABG obtained at 4 frequencies were 28.3 ± 12.26 and 9.18 ± 5.68 dB (P otitis media with cholesteatoma patients. However, there was no recurrence or new cholesteatoma formation in isolated retraction pockets or adhesive otitis patients.Oto-endoscopic eradication of the cholesteatoma or epithelial tissue from hidden area after the all visible cholesteatoma removal by oto-microscope improves the quality of surgery

    To study the extent of surface adenoid biofilm and to evaluate its role in the pathogenesis of chronic otitis media with effusion (COME) in children. The study was carried out on 100 children between 3 and 14 years of age, who were divided into two groups. The first group (50 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (50 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. Microbiological study, Scanning electron microscope and multiplex- PCR were done for suspected adenoid biofilms and specimens from middle ear effusion. Adenoids removed from children with COME had higher grade biofilm formation (74 %) than the second group (42 %). No correlation was found between adenoid size and biofilm formation. Culture of adenoid tissue in group 1 patients was positive in 52 % of cases compared to 96 % by PCR, while in group 2 culture of adenoid tissue was positive in 38 % compared to 48 % by PCR. Culture of middle ear fluid was positive in 32 % of cases only compared to 80 % by PCR. A positive correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected and identified by PCR technique. On the other hand, no correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected by culture. The size of the adenoid is not the main determinant factor in OME pathogenesis but the degree of bacterial colonization is much more important. Adenoids in COME may act as a reservoir of chronic infection rather than causing mechanical Eustachian obstruction. Higher grade biofilm formation was found in cases with middle ear effusion than those with adenoid hypertrophy only. These findings support the hypothesis that there would be an association between adenoidal biofilm formation and COME. This study focused on the value of PCR

    Full Text Available Gracias al descubrimiento de los antibióticos, la incidencia de complicaciones en las otitis medias agudas y crónicas ha descendido significativamente, aunque continúan siendo un peligro potencial de morbilidad y mortalidad. La disminución de las complicaciones puede condicionar retrasos diagnósticos por falta de sospecha clínica, enmascaramiento por tratamientos antibióticos previos y mal pronóstico, por lo cual siguen siendo procesos graves que ponen en peligro la vida del enfermo. Se definen actualmente con igual sistema de clasificación: extracraneales e intracraneales. Las primeras se subdividen en extratemporal e intratemporal, y constituyen un problema de salud en la población pediátrica a pesar del uso extendido de antibióticos. La evaluación clínico-otomicroscópica e imaginológica se reporta como criterio diagnóstico predictivo de sospecha y de confirmación. La parálisis facial, el vértigo, los vómitos, la cefalea, el dolor irradiado a la mastoides o a la región temporoparietal, y la hipertermia, deben alertar al médico sobre la presencia de una complicación supurada.Thanks to the discovery of antiobiotics, the incidence of complications in the chronic and acute otitis media has significantly decreased, though they remain a potential mortality and morbidity risk. The reduction of complications can be conditional on some diagnostic delays, on account of lack of clinical suspicions, symptoms disguised by previous antibiotic treatments and wrong prognosis; therefore, the complications continue to be severe processes that endanger the patient's life. They are currently classified as extracranial and intracranial. The former are divided into extratemporal and intratemporal and represent a health problem for the pediatric population despite the extended use of antibiotics. The clinical, otomicroscopic and imaging assessment is reported as a diagnostic criterion predictive of suspicions and of confirmation. Facial

    Full Text Available Abstract Introduction: A wide range of prostheses, autologus and synthetic are available for use these days. Ideally, the ossicular reconstruction prosthesis should be biocompatible, safe, easy to handle and capable of efficient sound transmission. Aim and objectives: To study operative ease and post-operative hearing results in patients undergoing ossiculoplasty with different types of prostheses. Materials and methods: A prospective randomized study of 25 patients with Chronic Otitis Media, undergoing ossiculoplasty was conducted at Command Hospital, Kolkata. Tragal cartilage was used in 05 patients, conchal cartilage in 05, refashioned incus in 05, hydroxyapatite in 05 and titanium prostheses in 05 patients. Subjects with mixed hearing loss, multiple co-morbidities and revision surgeries were excluded. Hearing assessment was done by pure tone audiometry pre-operatively and 04 and 12 weeks postoperatively. Results were analyzed statistically. Results: Using tragal or conchal cartilage took almost equal time as autologus incus. Using synthetic material saved time. Titanium prosthesis gives maximum surgical ease. Post-operative air-bone gap reduction within 20 dB was seen in all, irrespective of type of prostheses.  Conclusion: Surgical ease is considerably better with titanium prostheses; however hearing results are equally good in all.

    Otitis media (OM) is an inflammation of the middle ear associated with infection. Despite appropriate therapy, acute OM (AOM) can progress to chronic suppurative OM (CSOM) associated with ear drum perforation and purulent discharge. The effusion prevents the middle ear ossicles from properly relaying sound vibrations from the ear drum to the oval window of the inner ear, causing conductive hearing loss. In addition, the inflammatory mediators generated during CSOM can penetrate into the inner ear through the round window. This can cause the loss of hair cells in the cochlea, leading to sensorineural hearing loss. Pseudomonas aeruginosa and Staphylococcus aureus are the most predominant pathogens that cause CSOM. Although the pathogenesis of AOM is well studied, very limited research is available in relation to CSOM. With the emergence of antibiotic resistance as well as the ototoxicity of antibiotics and the potential risks of surgery, there is an urgent need to develop effective therapeutic strategies against CSOM. This warrants understanding the role of host immunity in CSOM and how the bacteria evade these potent immune responses. Understanding the molecular mechanisms leading to CSOM will help in designing novel treatment modalities against the disease and hence preventing the hearing loss. PMID:26248613

    Chronic suppurative otitis media (CSOM) is common among children in southern Africa. Managing associated co-morbidities may result in earlier disease resolution. Children 4 weeks were recruited to the study. Each child underwent a full clinical examination, a blood count, an HIV test and CD4 cell count, if found to be infected. The study included 86 children, and the median age was 4.6 years. HIV infection was present in 45 of 83 children (54.2%), of which 23 (51.1%) were receiving antiretroviral treatment at the time of presentation. Underweight was present in 22 of 85 (25.9%) children and in 17 of the 45 (37.8%) HIV-infected children. One or more clinical signs (not aural-related) were found in 46 of 86 (53.4%) children. Cholesteatoma was found in 23 of 113 (20.4%) ears, and 9 of 86 (10.5%) children had serious associated aural or intracranial complications. A high percentage of children with CSOM have associated pathology that needs to be diagnosed to optimally manage CSOM. © The Author [2014]. Published by Oxford University Press. All rights reserved.

    The aim of the study was to investigate whether Peptest, an immunoassay used to detect pepsin, could be used to diagnose extraesophageal reflux (EER) in children with chronic otitis media with effusion (OME). The results obtained using this fast, simple and non-expensive method were compared with the results of previous studies. Children 1-7 years old who had been diagnosed with OME and who were undergoing myringotomy with insertion of a ventilation tube were included in the prospective study. Middle ear fluid obtained during myringotomy was analyzed with Peptest to determine the presence of pepsin, and hence EER. Bilateral and unilateral myringotomy was performed in 15/44 (34.1%) and 29/44 (65.9%) children, respectively. Pepsin in the middle ear was detected in 14/44 (31.8%) children and in 19/59 (32.2%) middle ear specimens. Serous and mucous samples were positive for pepsin in 11/32 (34.4%) and 6/27 (22.2%) cases, respectively. Pepsin in the middle ear was detected in 3/7 children (42.9%) with bronchial asthma (p=0.662). Pepsin was detected in 1/3 of middle ear specimens of patients with OME. These patients probably suffer from more severe reflux and therefore would be potential candidates for antireflux therapy. However, this has to be confirmed in further studies.

    The present study shows that 2-3 weeks after medical treatment the status of middle ear mucosa in draining ears is similar to that of dry ears for at least 3 months. To measure the time required for an inflamed middle ear mucosa to return into optimal state after appropriate medical treatment in chronic suppurative otitis media (CSOM). To assess optimal timing for elective surgical treatment of draining ears in uncomplicated CSOM. In this prospective study, the Eustachian tube (ET) mucociliary clearance time (MCT) was used as the method to demonstrate the status of middle ear mucosa. In group 1 (28 patients) ET-MCT was measured in ears that were free of drainage for at least 3 months. In Group 2 (21 patients), ET-MCT was measured in draining ears, who responded to 10-14 days medical treatment, at presentation, after 10 days and 1 month. The ET-MCT was 8.63 ± 1.32 min in group 1 and 28.96 ± 8.19 min in group 2 at presentation; and the difference was statistically significant (p < 0.001). The ET-MCT was 14.76 ± 5.11 min after 10 days and 9.31 ± 2.33 min after 1 month in group 2. The ET-MCT was indifferent between groups 1 and 2 after 1 month (p = 0.235).

    To give an insight into why, when and where iatrogenic facial nerve (FN) injuries may occur and to explain how to deal with them in an emergency setting. Multicentre retrospective study in eight tertiary referral hospitals over 17 years. Twenty patients with partial or total FN injury during surgery for chronic otitis media (COM) were revised. Indication and type of surgery, experience of the surgeon, intra- and postoperative findings, value of CT scanning, patient management and final FN outcome were recorded. In 12 cases, the nerve was completely transected, but the surgeon was unaware in 11 cases. A minority of cases occurred in academic teaching hospitals. Tympanic segment, second genu and proximal mastoid segments were the sites involved during injury. The FN was not deliberately identified in 18 patients at the time of injury, and nerve monitoring was only applied in one patient. Before revision surgery, CT scanning correctly identified the lesion site in 11 of 12 cases and depicted additional lesions such as damage to the lateral semicircular canal. A greater auricular nerve graft was interposed in 10 cases of total transection and in one partially lesioned nerve: seven of them resulted in an HB III functional outcome. In two of the transected nerves, rerouting and direct end-to-end anastomosis was applied. A simple FN decompression was used in four cases of superficially traumatised nerves. We suggest checklists for preoperative, intraoperative and postoperative management to prevent and treat iatrogenic FN injury during COM surgery. © 2016 John Wiley & Sons Ltd.

    This study introduces a change-oriented short-form health-related quality of life questionnaire suited to symptoms of adult chronic middle ear disease and its consequences, and describes its properties. Two-centre prospective correlational study primarily for instrument development. Two otology secondary care centers in England. Fifty-two consecutive adult patients with active chronic otitis media undergoing surgery. The 12 items for the chronic otitis media benefit inventory (COMBI) were appraised chiefly for internal consistency of resulting score and for factor structure (exploratory factor analysis). The internal consistency of the COMBI was high within our cohort of patients, with a Cronbach's alpha value of 0.907. The three-factor solution from factor analysis explaining 73.6% of the variance was readily interpretable in terms of the intended item content: changes in hearing, ear symptoms, and daily activities plus healthcare uptake. The COMBI has suitable properties for the dynamic assessment of active chronic otitis media. Initial psychometric appraisal confirms its suitability for early adoption to acquire more comprehensive large-sample information with it and on it, for future refinement and application.

    The aim of the work was an evaluation of epidemiological factors in otitis media with effusion (OME) in children. Material consisted of 191 children treated surgically in Wroclaw ENT Clinic. The control group consisted of 95 healthy children. The evaluation was based on detailed history of the patients and physical ORL examination. The factors taken into considerations were: age, sex, birth factors, breast feeding, attending to kindergarten, passive smoking, social and environmental factors, incidents of upper respiratory airways and middle ear infections before OME being diagnosed. Frequent upper respiratory infections, acute and recurrent middle ear infections, staying with other children (kindergarten) and passive smoking increase the risk of OME incidence.

    The prevalence of otitis media in Greenlandic children is one of the highest in the world. International studies have shown that otitis-prone children may benefit from tubulation of the tympanic membrane. However, it is unknown whether these results can be applied to Greenlandic children and trials on the effects of ventilation tubes in high-risk populations have, to our knowledge, never been conducted. The trial is an investigator-initiated, multicentre, randomized, blinded superiority trial of bilateral ventilation tube insertion versus treatment as usual (no tube) in Greenlandic children aged 9-36 months with chronic otitis media with effusion or recurrent acute otitis media. With randomization stratified by otitis media subtype and trial site, a type 1 error of 5% and a power of 80%, a total of 230 participants are needed to detect a decrease of two visits to a health clinic during 2 years, which is considered the minimal clinical relevant difference. The primary outcome measure will be assessed blindly by investigating medical records. Secondary outcome measures are number of episodes of acute otitis media, quality of life, number of episodes of antibiotics administration and proportion of children with tympanic membrane perforations. This trial will provide evidence-based knowledge of the effects of ventilation tubes in children with middle ear infections from the high-risk Greenlandic population. Furthermore, this trial will improve the understanding of conducting randomized clinical trials in remote areas, where management of logistical aspects is particularly challenging.

    Full Text Available Background. Chronic suppurative otitis media (CSOM is a common public health problem worldwide and a major cause of hearing impairment especially in developing countries. The role of Mannose-Binding Lectin (MBL, a component of innate immunity, in CSOM has not been studied. The aim of the study was to examine whether MBL deficiency was more frequently present in cases group of tubotympanic CSOM patients rather than healthy subjects. Material and Methods. This was an analytic observational study. Subjects were enrolled in the Otorhinolaryngology Clinic at Margono Soekarjo Hospital, Purwokerto, Indonesia. An independent t-test was used to compare the mean of MBL serum concentration between tubotympanic CSOM subjects and control. Results. From 36 tubotympanic CSOM patients, there were 8 (22.22% patients with MBL deficiency (MBL level < 100 ng/ml, while no deficiency was found in the control group. The mean of MBL level in cases group was 354.88 ng/ml, with the lowest level being 0.001 ng/ml and the highest level 690.24 ng/ml, while in the control group MBL level mean was 376.27 with the lowest level being 188.71 and the highest level 794.54 ng/ml. Conclusion. There was no significant difference of MBL serum level between tubotympanic CSOM and control group. However, the presence of subjects with MBL deficiency in the tubotympanic CSOM group might be considered as playing a role in the tubotympanic CSOM.

    To assess eustachian tubal function (ETF) preoperatively in patients with chronic suppurative otitis media (CSOM) with central perforation by performing the inflation-deflation test. To correlate the results of the inflation-deflation test with the finding of aditus patency or block in patients with CSOM STUDY DESIGN: Prospective, cohort Tertiary care hospital Eighty adult patients with chronic suppurative otitis media and central perforation were recruited into the study. There were 45 males and 35 females. All patients underwent preoperative inflation-deflation test followed by cortical mastoidectomy and tympanoplasty. The patency of the aditus was assessed intraoperatively. Equalization of pressure on inflation-deflation test and intraoperative assessment of aditus patency Of a total of 80 patients, 49 patients were found to have discharging ears and 31 had dry ears at the time of surgery. In dry ears the inflation-deflation test had a sensitivity of 93% in predicting aditus patency although the specificity was lower at 67%. In discharging ears the sensitivity in predicting aditus patency was 72% and the specificity was 67%. The eustachian tube inflation-deflation test is a sensitive test for predicting aditus patency in patients with dry ears but less so in patients with discharging ears. Hence, it could be used in the former to avoid unnecessary exploration of the mastoid.

    Chronic otitis media with effusion (COME) is a prevalent upper airway infection resulting in hearing loss. The aim of this research was to determine risk factors for COME in preschool children. A case-control design was conducted in Auckland, New Zealand from May 2011 until November 2013. The cases were children aged 3 and 4 years referred for tympanostomy tube placement due to a diagnosis of COME (n = 178). The controls were a random sample of healthy children aged 3 and 4 years from primary care practices (n = 209). The children's guardians completed an interviewer-administered questionnaire that covered topics including socio-demographic information, pregnancy and birth, infant feeding practices, home environment, and respiratory health. In addition, skin prick tests for atopy were performed. Odds ratios (OR) estimating the risk of COME independently associated with the exposures were calculated using a logistic regression model. Children with COME frequently had nasal obstruction (OR: 4.38 [95% CI: 2.37-8.28]), always snored (OR: 3.64 [95% CI: 1.51-9.15]) or often snored (OR: 2.45 [95% CI: 1.04-5.96]), spent more hours per week in daycare (OR per hour/week: 1.03 [95% CI: 1.00-1.05]), had frequent colds (OR: 2.67 [95% CI: 1.59-4.53]), had siblings who had undergone tympanostomy tube placement (OR: 2.68 [95% CI: 1.22-6.02]), underwent long labour (OR: 2.59 [95% CI: 1.03-6.79]), and had early introduction of cow's milk (OR: 1.76 [95% CI: 1.05-2.97]). Asian ethnicity (OR: 0.20 [95% CI: 0.07-0.53]) and having older siblings (OR: 0.54 [95% CI: 0.31-0.93]) were inversely associated with COME. COME in preschool children was associated with pathogen exposure, respiratory infection, and nasal obstruction. Strategies to prevent pathogen transmission warrant investigation. The novel findings of long labour and early cow's milk introduction require replication in future studies.

    Otitis media (OM) has been observed at elevated prevalence rates in Greenlandic children. OM associated hearing loss (HL) may compromise the children's linguistic skills, social development and educational achievements. We investigated the prevalence of chronic suppurative otitis media (CSOM), otitis media with effusion (OME) and tympanic membrane sequelae of OM, and compared the corresponding hearing thresholds. In 2010 we examined a cohort of 223 Greenlandic children aged 4-10 years by video otoscopy, tympanometry and tested hearing thresholds for the low-frequencies: 500, 1000 and 2000Hz and the high-frequencies: 4000 and 6000Hz. HL was categorized according to the worst hearing ear and was compared within the groups: CSOM, OME, tympanic membrane sequelae of OM and normal. Of 207 children, 5.8% had CSOM, 13.9% had OME and 55.6% had tympanic membrane sequelae of OM. The median pure tone average in low-frequencies/high-frequencies were: CSOM: 34.2/31.3dB, OME: 23.3/22.5dB, Sequelae of OM: 13.3/15dB and normal ears: 11.7/12.5dB. We found a significant difference (pchildren a HL>15dB in any frequency was found, while 6.5% suffered from a bilateral low-frequency HL>25dB. The severity of OM significantly corresponded to increased HL. The burden of CSOM and HL remains high in young Greenlandic children. Aggressive treatment with antibiotics, improved hearing rehabilitation, sound field amplification in classrooms and otosurgical capacity should be further promoted in Greenland.

    Eosinophilic otitis media is an intractable inflammation of the middle ear combined with bronchial asthma. According to a national epidemiological investigation on eosinophilic otitis media, it is assumed that eosinophilic otitis media are combined with sinusitis in about 74% of their cases. On the other hand, organizational images of eosinophilic otitis media and eosinophilic sinusitis are similar, and steroid therapy is effective together, and it is thought that they are involved in the idea of one airway one disease, but the details of sinusitis combined with the eosinophilic otitis media are unidentified. Therefore, we examined the kinds of the sinusitis combined with eosinophilic otitis media. We diagnosed 18 cases (male: 2 cases, female: 16 cases) (average age: 54.6 years old) as eosinophilic otitis media according to the diagnostic criteria. And, by the CT views of a paranasal sinus, blood tests, existence of the nasal polyp, etc, we investigated the kinds of sinusitis combined with eosinophilic otitis media. It turned out that bronchial asthma was combined with eosinophilic otitis media in 17 of 18 cases (airway hypersensitivity did sthenia of one case, but the asthma did not yet developed), and 6 cases were combined with aspirin induced asthma (AIA), and 3 cases were combined with Churg-Strauss syndromes (CSS). 10 case (55.6%) of 17 eosinophilic otitis media were combined with eosinophilic sinusitis. And 4 cases (22.2%) of 17 eosinophilic otitis media were combined with chronic sinusitis, 4 cases (22.2%) of 17 eosinophilic otitis media were not combined with sinusitis. We concluded that eosinophilic otitis media was not always combined with eosinophilic sinusitis. The idea of one airway one disease was not applied to this examination. (author)

    M.T. Goodarzi

    2013-07-01

    Full Text Available Introduction & Objective: The diagnostic value of endoscopic and microscopic procedures for viewing different structures of middle ear has been widely assessed however, no published study is available for comparing the diagnostic value of them in chronic otitis media patients. The present study conducted to compare diagnostic value of these two procedures for as-sessment of middle ear normal structures and possible defects in these patients. Materials & Methods: In a prospective descriptive analytical study, fifty eight consecutive pa-tients older than 15 years who suffered from chronic otitis media and were candidates for tympanoplasty with or without mastoidectomy were included into the study and underwent operation. After entering the middle ear by post auricular incision and elevation of a tym-panomeatal flap, and prior to surgery , the middle ear was first examined by an operating mi-croscope in different bed and microscope positions and by performing gentle maneuvers on the head and then was reevaluated using a rigid 0 & 30 degree sinoscope. The visible areas of middle ear were separately noted. Results: Structures of epitympanum, posterior mesotympanum, and hypotympanum structures were more visible using endoscope compared with microscope(P0.05. Conclusion: Endoscopic and microscopic procedures had similar diagnostic values to view ossicular chain mobility and reflexes of round window as well as to detect ossicular chain erosions, but different anatomical parts and more hidden pits of the middle ear such as epitympanum, posterior mesotympanum, and hypotympanum are more visible by an endoscopic tool.In case of pathologic conditions, endoscopic approach is recommended for better observation and adequate evaluation of the location before and after the removal of the lesion.

    Objective We aimed to summarize key articles published between 2011 and 2015 on the treatment of (recurrent) acute otitis media, otitis media with effusion, tympanostomy tube otorrhea, chronic suppurative otitis media and complications of otitis media, and their implications for clinical practice. Data Sources PubMed, Ovid Medline, the Cochrane Library, and Clinical Evidence (BMJ Publishing). Review Methods All types of articles related to otitis media treatment and complications between June 2011 and March 2015 were identified. A total of 1122 potential related articles were reviewed by the panel members; 118 relevant articles were ultimately included in this summary. Conclusions Recent literature and guidelines emphasize accurate diagnosis of acute otitis media and optimal management of ear pain. Watchful waiting is optional in mild to moderate acute otitis media; antibiotics do shorten symptoms and duration of middle ear effusion. The additive benefit of adenoidectomy to tympanostomy tubes in recurrent acute otitis media and otitis media with effusion is controversial and age dependent. Topical antibiotic is the treatment of choice in acute tube otorrhea. Symptomatic hearing loss due to persistent otitis media with effusion is best treated with tympanostomy tubes. Novel molecular and biomaterial treatments as adjuvants to surgical closure of eardrum perforations seem promising. There is insufficient evidence to support the use of complementary and alternative treatments. Implications for Practice Emphasis on accurate diagnosis of otitis media, in its various forms, is important to reduce overdiagnosis, overtreatment, and antibiotic resistance. Children at risk for otitis media and its complications deserve special attention.

    The objective of the present study was the determination of the incidence of gastroesophageal reflux disease and the evaluation of its possible influence on the development and duration of chronic exudative otitis media in the children during the first year of life. A total of 141 infants at the age of 3 months presenting with exudative otitis media refractory to the conservative treatment throughout the first 1-1.5 months of life were available for the examination. The effectiveness of the anti-reflux therapy was estimated based on the middle ear condition (the presence or absence of exudate) within 3 and 6 months after the initiation of the treatment. The signs of aspiration of gastric chimus and gastroesophageal reflux disease were documented in 92% of the cases. The anti-reflux treatment during 3 months resulted in the disappearance of the manifestations of exudative otitis media in 43% of the patients. The further prolongation of such therapy up to 6 months allowed to normalize the state of the middle ear in 69% of the children although the remaining 40% failed to respond. It is concluded that the treatment of the children presenting with exudative otitis media during first year of life should be performed taking into consideration the possible involvement of gastroesophageal reflux disease in pathogenesis of this pathological condition.

    Proteolytic enzymes such as pepsine or papaine are able to split IgG antibodies into large fragments in vitro. These immunoglobulin fragments (IgG, IgA, IgM) were now detected in vivo from the purulent secretions of cholesteatoma, chronic otitis media and radical mastoid cavities. During chronic otitis media the intact immunoglobulins are split due to the proteolytic activity of neutral proteinases. These fragments were qualitatively and quantitatively investigated by means of various immunological procedures. After the immunoelectrophoretic separation of the purulent middle-ear-secretions and after diffusion against anti-IgG-, anti-IgA- and anti-IgM- serum double precipitate lines could be observed especially in middle-ear-secretion with a bacterial flora of pseudomonas aeruginosa (pyocyanea) and of the proteus-providencia-group. This was the first proof of the presence of split products of the immunoglobulins. The exact demonstration of these split products could be carried out by gel-filtration and fractionation of the intact and split immunoglobulins. During chronic otitis media intact immunoglobulins are split by leucocytic and extracellular bacterial proteinases into fragments of different molecular weight. The most malignant extracellular proteinases with the greatest proteolytic activity against intact immunoglobulins are the bacterial proteinases of pseudomonas aeruginosa. These proteinases can not be inhibited by the other serum proteinaseinhibitors except for alpha-2-macroglobulin of the human blood serum. This inhibitor has a very high molecular weight so that we can not find it in a higher concentration in the middle-ear-secretion. We can liberate this inhibitor by injuring the blood vessels during a tympanoplasty. In this way we get an inhibitory effect against these proteinases and combined with an appropriate antibiotic therapy we can cure a chronic otitis media.

    Previous reports indicated that middle ear surgery might partially improve tinnitus after surgery. However, until now, no influencing factor has been determined for tinnitus outcome after middle ear surgery. The purpose of this study was to investigate the association between preoperative air-bone gap and tinnitus outcome after tympanoplasty type I. Seventy-five patients with tinnitus who had more than 6 months of symptoms of chronic otitis media on the ipsilateral side that were refractory to medical treatment were included in this study. All patients were evaluated through otoendoscopy, pure tone/speech audiometer, questionnaire survey using the visual analog scale and the tinnitus handicap inventory for tinnitus symptoms before and 6 months after tympanoplasty. The influence of preoperative bone conduction, preoperative air-bone-gap, and postoperative air-bone-gap on tinnitus outcome after the operation was investigated. The patients were divided into two groups based on preoperative bone conduction of less than 25dB (n=50) or more than 25dB (n=25). The postoperative improvement of tinnitus in both groups showed statistical significance. Patients whose preoperative air-bone-gap was less than 15dB showed no improvement in postoperative tinnitus using the visual analog scale (p=0.889) and the tinnitus handicap inventory (p=0.802). However, patients whose preoperative air-bone-gap was more than 15dB showed statistically significant improvement in postoperative tinnitus using the visual analog scale (ptinnitus handicap inventory (p=0.016). Postoperative change in tinnitus showed significance compared with preoperative tinnitus using visual analog scale (p=0.006). However, the correlation between reduction in the visual analog scale score and air-bone-gap (p=0.202) or between reduction in tinnitus handicap inventory score and air-bone-gap (p=0.290) was not significant. We suggest that the preoperative air-bone-gap can be a predictor of tinnitus outcome after

    The findings of computed tomography (CT) of 89 patients clinically suspected of having otitis media were studied in this work. Such results were compared to clinical diagnosis, otoscopy, surgical findings and previous data. Among the results of our analysis, we studied seven patients with acute otitis media and 83 patients with chronic otitis media. The patients with acute otitis media have undergone CT examinations to evaluate possible spread to central nervous system. The diagnosis of cholesteatoma, its extension and complications were the main indication. for chronic otitis media study. The main findings of the cholesteatomatous otitis were the occupation of the epitympanun, the bony wall destruction and the ossicular chain erosion. The CT demonstrated a great sensibility to diagnose the cholesteatoma. (author)

    Full Text Available BACKGROUND Chronic Suppurative Otitis Media (CSOM is one of the most common diseases of younger age in middle class population of the developing countries. Loss of hearing due to CSOM has a role in learning and intelligence of the students. There are multiple factors, which affect the tympanic membrane repair, mastoidectomy is one. MATERIALS AND METHODS This study at Era’s Lucknow Medical College and Hospital was planned to assess the effect of cortical mastoidectomy in safe type CSOM. For that, 120 patients were taken who were divided in two groups of 60 each. One group was subjected to tympanoplasty type 1 and other to cortical mastoidectomy and type 1 tympanoplasty. RESULTS After six months of follow up, it was found that graft rejection was 13 in group 1 compared to 12 in group2 and cortical mastoidectomy has almost no effect on graft acceptance and hearing gain in pure tone audiometry. CONCLUSION This study was planned to find the effect of cortical mastoidectomy in tympanoplasty type 1 in safe type CSOM. Two groups of 60 patients were taken. In one group, only tympanoplasty type 1 while in other cortical mastoidectomy along with tympanoplasty type 1 was done. After 6 months of follow up, no statistically significant difference was found in the graft rejection and hearing gain between the two groups.

    Full Text Available Chronic Otitis Media (COM is characterized by middle ear effusion (MEE and conductive hearing loss. MEE reflect mucus hypersecretion, but global proteomic profiling of the mucosal components are limited.This study aimed at characterizing the proteome of MEEs from children with COM with the goal of elucidating important innate immune responses.MEEs were collected from children (n = 49 with COM undergoing myringotomy. Mass spectrometry was employed for proteomic profiling in nine samples. Independent samples were further analyzed by cytokine multiplex assay, immunoblotting, neutrophil elastase activity, next generation DNA sequencing, and/or immunofluorescence analysis.109 unique and common proteins were identified by MS. A majority were innate immune molecules, along with typically intracellular proteins such as histones and actin. 19.5% percent of all mapped peptide counts were from proteins known to be released by neutrophils. Immunofluorescence and immunoblotting demonstrated the presence of neutrophil extracellular traps (NETs in every MEE, along with MUC5B colocalization. DNA found in effusions revealed unfragmented DNA of human origin.Proteomic analysis of MEEs revealed a predominantly neutrophilic innate mucosal response in which MUC5B is associated with NET DNA. NETs are a primary macromolecular constituent of human COM middle ear effusions.

    Full Text Available Objectives. Detection of extraesophageal reflux (EER in children with chronic otitis media with effusion (OME using three different diagnostic methods. Methods. Children between 1 and 7 years with OME who underwent adenoidectomy and myringotomy with insertion of a ventilation tube were included in this prospective study. 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 an adenoid specimen was done immunohistochemically. Results. Altogether 21 children were included in the study. Pathological oropharyngeal pH was confirmed in 13/21 (61.9% children. Pepsin in the middle ear fluid was present in 5/21 (23.8% children; these 5 patients were diagnosed with the most severe EER established through monitoring of oropharyngeal pH. No specimen of adenoids tested was positive for pepsin upon immunohistochemical examination. Conclusions. Diagnosis of EER in patients with OME using Restech is sensitive but less specific when compared to the detection of pepsin in middle ear fluid using Peptest. Pepsin in the middle ear was consistently present in patients with RYAN score above 200, and these patients in particular could potentially profit from antireflux therapy.

    In an institutional review board-approved study, 25 pediatric subjects diagnosed with chronic or recurrent otitis media were observed over a period of six months with optical coherence tomography (OCT). Subjects were followed throughout their treatment at the initial patient evaluation and preoperative consultation, surgery (intraoperative imaging), and postoperative follow-up, followed by an additional six months of records-based observation. At each time point, the tympanic membrane (at the light reflex region) and directly adjacent middle-ear cavity were observed in vivo with a handheld OCT probe and portable system. Imaging results were compared with clinical outcomes to correlate the clearance of symptoms in relation to changes in the image-based features of infection. OCT images of most all participants showed the presence of additional infection-related biofilm structures during their initial consultation visit and similarly for subjects imaged intraoperatively before myringotomy. Subjects with successful treatment (no recurrence of infectious symptoms) had no additional structures visible in OCT images during the postoperative visit. OCT image findings suggest surgical intervention consisting of myringotomy and tympanostomy tube placement provides a means to clear the middle ear of infection-related components, including middle-ear fluid and biofilms. Furthermore, OCT was demonstrated as a rapid diagnostic tool to prospectively monitor patients in both outpatient and surgical settings.

    Objective: To diagnose common organisms causing Chronic Suppurative Otitis Media (CSOM) and their in vitro sensitivity. Methodology: This descriptive study was carried out at Ear Nose and Throat (ENT) Department, Combined Military Hospital (CMH) Multan from July 2014 to June 2015. A total of 140 patients with active CSOM were included in this study. Ear swabs were collected from the discharging ear and sent for aerobic cultures only. Antibiotic sensitivity testing was done with standard antibiotic discs using Kirby Bauer disk diffusion method. Results: Pathogens were isolated in all except 13 ears. Pseudomonas aeruginosa was the most common organism isolated alone in 76 ears and in combination with other micro-organisms in 18 ears, followed by staphylococcus aureus in 23 and MRSA in four ears. Mixed organisms were found in 20 patients. Antibiotic sensitivity of Pseudomonas aeruginosa showed that 100% isolates were sensitive to imipenem and meropenem while Staphylococcus aureus was 100% sensitive to Chloramphenicol. Conclusion: Pseudomonas aeruginosa and staphylococcus aureus were commonest organism isolated in CSOM. Similar studies should periodically be conducted in various regions to have a current knowledge of the offending organisms and their sensitivity patterns against various antibiotics before commencing treatment of CSOM.

    To compare the number of fungiform taste buds among patients with chronic otitis media (COM), those with pars flaccida retraction type cholesteatoma, and those with pars tensa retraction type cholesteatoma in combination with gustatory function. Thirty-seven patients with COM, 22 patients with pars flaccida retraction type cholesteatoma, and 17 patients with pars tensa retraction type cholesteatoma were included. An average of 10 fungiform papillae (FP) per patient in the midlateral region of the tongue were observed by confocal laser scanning microscopy in vivo, and the average number of taste buds were counted. Just before the observation of FP, electrogustometry (EGM) was performed to evaluate gustatory function. A significant decrease of the average number of fungiform taste buds and significant elevation of EGM thresholds were clarified in the pars tensa retraction type cholesteatoma group but not in the COM or pars flaccida type cholesteatoma group. It was suggested that some neurotoxic cytokines produced by cholesteatoma tissue might affect the CTN morphology, resulting in a decreased number of fungiform taste buds and elevation of EGM threshold in patients with pars tensa retraction type cholesteatoma. © The Author(s) 2016.

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

    ABSTRACT Otitis media (inflammation of the middle ear) is one of the most common diseases of early childhood. Susceptibility to otitis is influenced by a number of factors, including the actions of innate immune molecules secreted by the epithelia lining the nasopharynx, middle ear and Eustachian tube. The SPLUNC1 (short palate, lung, nasal epithelial clone 1) protein is a highly abundant secretory product of the mammalian nasal, oral and respiratory mucosa that is thought to play a multifunctional role in host defense. In this study we investigated Splunc1 expression in the ear of the mouse, and examined whether this protein contributes to overall host defense in the middle ear and/or Eustachian tube. We found that Splunc1 is highly expressed in both the surface epithelium and in submucosal glands in these regions in wild-type mice. In mice lacking Splunc1, we noted histologically an increased frequency of otitis media, characterized by the accumulation of leukocytes (neutrophils with scattered macrophages), proteinaceous fluid and mucus in the middle ear lumens. Furthermore, many of these mice had extensive remodeling of the middle ear wall, suggesting a chronic course of disease. From these observations, we conclude that loss of Splunc1 predisposes mice to the development of otitis media. The Splunc1−/− mouse model should help investigators to better understand both the biological role of Splunc1 as well as host defense mechanisms in the middle ear. PMID:25765466

    Full Text Available Background. Lemierre’s syndrome is septic thrombophlebitis of the internal jugular vein, initiated by an infection of the head and neck region. This septic thrombophlebitis gives rise to septic microemboli that can disseminate throughout the body to form septic infarctions and abscesses, with the most frequent site being pulmonary. Methods. We discuss the case of a 14-year-old male with Lemierre’s syndrome as a complication of chronic middle ear infection. Results. The patient developed septic shock and microemboli, and subsequently died. Conclusion. This case report illustrates that untreated chronic middle ear infection can lead to potentially fatal complications such as Lemierre’s syndrome, and emphasises the importance of timeous treatment of chronic middle ear pathology.

  19. High-frequency conductive hearing loss as a diagnostic test for incomplete ossicular discontinuity in non-cholesteatomatous chronic suppurative otitis media.

    Directory of Open Access Journals (Sweden)

    Krishnamurti M A Sarmento

    Full Text Available Chronic suppurative otitis media, with or without cholesteatoma, may lead to erosion of the ossicles and discontinuity of the ossicular chain. In incomplete ossicular discontinuity (IOD, partial erosion of the ossicles occurs, but some sound transmission is noted throughout the ossicular chain. High-frequency conductive hearing loss (HfCHL has been considered a hallmark of incomplete ossicular discontinuity. This study aims to evaluate the use of HfCHL as a preoperative predictor of IOD in patients with non-cholesteatomatous chronic suppurative otitis media. The HfCHL test was defined as the preoperative air-bone gap (ABG at 4 kHz minus the average of the ABG at 0.25 and 0.5 kHz. The test was applied in 328 patients before surgery and compared to intraoperative findings as the gold standard. At surgery, 201 (61.3% patients had an intact ossicular chain, 44 (13.4% had a complete ossicular discontinuity, and 83 (25.3% exhibited an IOD. The best cutoff level was calculated as 10 dB. The HfCHL test to diagnose IOD had a sensitivity of 83% and a specificity of 92% with a post-test probability of 78% and a likelihood ratio of 10.2. We concluded that the HfCHL test is highly effective in predicting IOD in patients with non-cholesteatomatous chronic suppurative otitis media and that it should be used routinely as a screening test prior to surgery.

    Invasive aspergillosis (IA) is a severe disseminated fungal disease that occurs mostly in immunocompromised patients. However, central nervous system IA, combining meningitis and skull base involvement, does not occur only in groups with classic risk factors for IA; patients with chronic renal failure and diabetes mellitus are also at risk for more chronic forms. In both of our proven IA cases, voriconazole monotherapy was effective without surgery, and cerebrospinal fluid and serum 1,3-β-d-glucan test results were initially positive, in contrast to galactomannan antigen results.

    Full Text Available Introduction: Surgically treated intracranial suppurations (ICS are uncommon, life-threatening neurosurgical emergencies. They can result from complication of chronic suppurative otitis media (CSOM and bacterial rhinosinusitis (BRS. The objective of this study was to know the frequency of BRS and CSOM and relate it to its rare complication of surgically treated ICS while also describing the demography, type and outcome of ICS that resulted from BRS and CSOM. Materials and Methods: All patients that presented to the Otorhinolaryngological department and Neurosurgical unit of the same institution with clinical and radiological features of CSOM, BRS, and ICS were prospectively studied over a 5-year period. Patients were followed up for a minimum of 3 months. Results: Two thousand, two hundred and seventy-nine patients presented during the 5-year study period. Of all these patients, 1511 had CSOM (66.3% and 768 (33.7% presented with features of BRS. Eleven (0.73% had ICS complicating their CSOM while 8 (1.04% cases of surgically treated ICS followed BRS. Bacterial rhinosinusitis was not more likely to lead to ICS (P = 0.4348. The Odds ratio (OR of a child ≤ 18 years of age with CSOM developing ICS was 5.24 (95% Confidence interval 1.13-24.34; P = 0.0345, while it was 7.60 (95% Confidence interval 1.52-37.97; P = 0.0134 for children with BRS. Conclusions: The most common type of ICS complicating CSOM and BRS was brain abscess and subdural empyema, respectively. Children are more prone to develop surgical ICS following CSOM and BRS. The proportion of males that had ICS was higher in both CSOM and BRS patients. Optimal outcome is achieved in patients that presented with GCS of 13 and above.

    Full Text Available Purpose: Chronic otitis media with effusion (OME is the leading cause of hearing loss during childhood. In bacterial etiology of OME, the most frequent pathogens responsible are Haemophilus influenzae followed by Streptococcus pneumoniae and Moraxella catarrhalis . This study aimed at evaluating the accuracy of nasopharyngeal (NP specimens in the identification of pathogens in the middle ear fluid (MEF in patients with OME. Materials and Methods: In this cross sectional, case-control study, 95 MEFs and 53 NP secretion specimens were obtained from 53 children. As a control group, 102 NP specimens were taken from children having an operation other than an otological disease. Conventional culture methods and multiplex-PCR method have been used to determine the etiology of OME; NP carriage between cases and control groups were compared using conventional culture methods. Pearson Chi-Square and Fisher′s Exact tests were used in statistical analysis. Results : Bacteria were isolated by culture in 37.9% of MEF specimens, 14.7% of which belonged to the group H. influenzae , S. pneumoniae and M. catarrhalis. PCR was positive in 30.5% specimens targeting the same pathogens. There was a two-fold increase in carriage rate of S. pneumoniae and H. influenzae in patients than controls for each pathogen. Conclusion: PCR is a more reliable method to detect middle ear pathogens in MEF in comparison with the conventional culture methods. The NP colonization wasn′t found to be an indicator of the pathogen in MEF although middle ear pathogens colonize more in nasopharynx of diseased children.

    Full Text Available Background: Chronic suppurative otitis media (CSOM is one of the leading causes of preventable disabling hearing impairment (DHI in developing countries. Early detection and management complements advances made in other survival programs, improves work capacity, and enhances learning opportunities for school children. We aimed to determine the prevalence of CSOM and associated DHI among school children aged six to 16 years in Socotra Island, Yemen. Methods: We conducted a cross-sectional community-based survey, from 20 April 2011 to 20 June 2011. The study procedures involved completing a questionnaire, an otoscopic ear examination, an audiometric test of hearing, and tuning fork tests for the type of DHI. Results: A total of 686 children were interviewed and examined for CSOM and associated DHI of CSOM cases. The prevalence of CSOM was 7.4%, (95% CI 5.5–9.4. CSOM status was significantly associated with DHI (p=0.001, but no significant associations were found between demographic characteristics and CSOM status. Logistic regression identified four significant independent contributing factors: history of ear discharge in the last 12 months (odds ratio (OR 7.8, 95% CI 3.9–15.6; swimming in local pools (OR 6.0, 95% CI 1.4–25.4; recurrent respiratory tract infection more than three times per year (OR 5.3, 95% CI 2.5–11.0; and overcrowding with more than three families per house (OR 4.4, 95% CI 1.7–11.5. . Conclusion: The burden of CSOM in the children studied indicates a high level of DHI in these communities within Yemen. A history of ear discharge, swimming in local pools, recurrent respiratory infections, and overcrowded housing were the strongest predictors for CSOM. There is a need for better ear care and screening programs for early detection and management of this disease.

    Background The performance of nationwide studies of chronic otitis media (COM) in adults has been insufficient in Korea. We evaluated the prevalence and risk factors of COM in Korea. Methods This study was conducted using data from the fifth Korean National Health and Nutrition Examination Survey (n = 23,621). After excluding the subjects under 20 year old and suffered from cancers, 16,063 patients were evaluated for COM. Participants underwent a medical interview, physical examination, endoscopic examination, and blood and urine test. COM was diagnosed by trained residents in the Department of Otorhinolaryngology using an ear, nose, and throat questionnaire and otoendoscopy findings. Data on the presence and absence of COM were collected. Multivariate logistic regression analyses were performed to identify its risk factors. Results Of the 16,063 participants aged above 20 year old, the weighted prevalence of COM was 3.8%. In the multivariate analyses, the following factors showed high odds ratios (ORs) for COM: pulmonary tuberculosis (adjusted OR, 1.78; 95% confidence interval [CI], 1.06-3.01), chronic rhinosinusitis (adjusted OR, 1.87; 95% CI, 1.17-2.98), mild hearing impairment (adjusted OR, 1.95; 95% CI, 1.34-2.85), moderate hearing impairment (adjusted OR, 4.00; 95% CI, 2.21-7.22), tinnitus (adjusted OR, 1.82; 95% CI, 1.34-2.49), increased hearing thresholds in pure tone audiometry in the right ear (adjusted OR, 1.02; 95% CI, 1.01-1.03), and left ear (adjusted OR, 1.03; 95% CI, 1.02-1.04). The following factors showed low odds ratios for COM: hepatitis B (adjusted OR, 0.28; 95% CI, 0.08-0.94) and rhinitis (adjusted OR, 0.60; 95% CI, 0.42-0.88). In addition, high levels of vitamin D, lead, and cadmium, EQ-5D index; and low red blood cell counts were associated with development of COM (Student’s t-test, P < 0.01). Conclusions Our population-based study showed that COM is not rare in Korea, and its development may be associated with various host and

    Chronic otitis media (COM) can be treated with tympanoplasty with or without mastoidectomy. In patients who have undergone middle ear surgery, three-dimensional spiral computed tomography (CT) scan plays an important role in optimizing surgical planning. This study was performed to compare the findings of three-dimensional reconstructed spiral and conventional CT scan of ossicular chain study in patients with COM. Fifty patients enrolled in the study underwent plane and three dimensional CT scan (PHILIPS-MX 8000). Ossicles changes, mastoid cavity, tympanic cavity, and presence of cholesteatoma were evaluated. Results of the two methods were then compared and interpreted by a radiologist, recorded in questionnaires, and analyzed. Logistic regression test and Kappa coefficient of agreement were used for statistical analyses. Sixty two ears with COM were found in physical examination. A significant difference was observed between the findings of the two methods in ossicle erosion (11.3% in conventional CT vs. 37.1% in spiral CT, P = 0.0001), decrease of mastoid air cells (82.3% in conventional CT vs. 93.5% in spiral CT, P = 0.001), and tympanic cavity opacity (12.9% in conventional CT vs. 40.3% in spiral CT, P=0.0001). No significant difference was observed between the findings of the two methods in ossicle destruction (6.5% conventional CT vs. 56.4% in spiral CT, P = 0.125), and presence of cholesteatoma (3.2% in conventional CT vs. 42% in spiral CT, P = 0.172). In this study, spiral CT scan demonstrated ossicle dislocation in 9.6%, decrease of mastoid air cells in 4.8%, and decrease of volume in the tympanic cavity in 1.6%; whereas, none of these findings were reported in the patients' conventional CT scans. Spiral-CT scan is superior to conventional CT in the diagnosis of lesions in COM before operation. It can be used for detailed evaluation of ossicular chain in such patients

    The objective of the authors' study was to investigate the predictive value of the neutrophil-lymphocyte rate (NLR) and platelet-lymphocyte rate (PLR) in otitis media with effusion and the correlation of the effusion type with these ratios. Retrospective case-control study. One hundred twenty-six pediatric patients diagnosed otitis media with chronic effusion and had ventilation tube inserted between October 2015 and July 2016 were included in the study group and 124 healthy children, who applied for the routine examination and had blood count analysis, were included in the control group. The patients in the study group were divided into 2 groups regarding the effusion viscosity, which was obtained from the patients' operation files. Seventy-one patients were included in the serous group and 55 patients in the mucous group. The NLR and PLR rates of the groups were compared and statistically evaluated. The average NLR and PLR rates were significantly higher in the study group than in the control group (P = 0.000, P = 0.004 respectively). Comparison of the serous and mucous groups with the control group revealed a significant difference between the control group and the serous group regarding the NLR and PLR (P = 0.000; P = 0.000 respectively), but not between the control group and mucous group (P = 0.694; P = 0.691 respectively). Neutrophil-lymphocyte rate and PLR had a predictive value for otitis media with effusion and additionally it was a laboratory indicator supporting the typing of the viscosity of the fluid accumulated in the middle ear.

    Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy.

    Recently, demand for and supply of short-form patient-reported outcome measures (PROMs) have risen throughout the world healthcare. Our contribution to meeting that demand has been translating and culturally adapting the Chronic Otitis Media Questionnaire-12 (COMQ-12) for adults into Serbian and enhancing its psychometric base on the relatively large Serbian COM caseload. Chronic otitis media can seriously affect quality of life progressively and in long-term, and it remains the major source of hearing problems in the developing world. The translated questionnaire was given twice to 60 adult patients with chronic otitis media of three types (inactive, active mucosal and active squamous disease) and to 60 healthy volunteers. Both patients and volunteers also filled the generic Short-Form 36 questionnaire (SF-36). Conventional statistical procedures were used in strategically driven development of scoring. Additionally, item responses were scaled by linear mapping against the provisional total score. Generalizability, detailed factor interpretation and supportability of scores were criteria, for the best compromise factor solution. Test-retest reliability was very high (0.924 to 0.989, depending on score). The a priori content dimensions of the questionnaire were strongly supported by 3-factor exploratory and confirmatory factor analyses for content validity, separating (i) ear symptoms from (ii) hearing problems, from (iii) daily activity restriction plus healthcare uptake. The 3-factor structure was furthermore highly stable on replication. The very large effect sizes when contrasting patients with healthy volunteers, and active with inactive disease established construct validity for the total score. A strong association with disease activity and a moderate one with generic health-related quality of life (HRQoL), the SF-36, supported construct validity for two of three factors extracted (ear symptoms, and impact on daily activities plus healthcare uptake).

    Otitis media is one of the most prevalent childhood diseases. The impact of otitis media on quality of life of Portuguese children is unknown, because of the unavailability of a tool validated in European Portuguese to assess this consequence of otitis media. The Otitis Media-6 questionnaire (Otitis Media-6) is the most frequently used tool to assess health-related quality of life in children with otitis media. This study aims to create a version in the Portuguese language and culturally adapted to Portugal of the otitis media-6 questionnaire. The Otitis Media-6 questionnaire was translated and culturally adapted to the Portuguese language and population. Then, to assess the instrument psychometric properties, it was applied to a sample of Portuguese children with chronic otitis media with effusion or recurrent acute otitis media. The Portuguese version of Otitis Media-6 questionnaire demonstrated the following psychometric properties: construct validity for baseline (rs = 0.98) and change scores (rs = 0.97), internal consistency (α = 0.780), test-retest reliability (rs = 0.89) and responsiveness to clinical change (t(59) = 10.104). The simplicity and brevity of application of the instrument make it ideal for use in research and in clinical practice, enabling a more objective assessment of the extension of the otitis media impact in children quality of life and a more targeted therapeutic decision. The Portuguese version of the Otitis Media-6 questionnaire is a valid, reliable and sensitive instrument to evaluate the health-related quality of life in Portuguese children with otitis media.

    Full Text Available Introduction Despite the advent of antibiotics and immunizations in the last century, complications of otitis media remain quite frequent, have high morbidity and mortality rates, and pose a challenge to the otorhinolaryngologist. Objective To establish the annual incidence of intratemporal complications of otitis media and prospectively evaluate patients via an analysis of epidemiologic and clinical aspects. Methods Prospective, observational study. Between February 2010 and January 2011, patients admitted to a tertiary care, university-based otology practice with diagnosis of otitis media and an associated intratemporal complication (ITC were included in the study. The following data were evaluated: age, sex, type of ITC, treatment, imaging tests findings, type and degree of hearing loss, and clinical outcome. The overall incidence of all complications and of each complication individually was determined. Results A total of 1,816 patients were diagnosed with otitis media. For 592 (33% individuals, the diagnosis was chronic otitis media; for 1,224 (67%, the diagnosis was acute otitis media. ITCs of otitis media were diagnosed in 15 patients; thus, the annual incidence of intratemporal complications was 0.8%. We identified 19 ITC diagnoses in 15 patients (3 patients had more than one diagnosis. Labyrinthine fistulae were diagnosed in 7 (36.8% individuals, mastoiditis in 5 (26.3%, facial palsy in 4 (21.1%, and labyrinthitis in 3 (15.8%. Conclusion The incidence of intratemporal complications in Brazil remains significant when compared with developed countries. Chronic otitis media with cholesteatoma is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

    Physicians should ideally be able to provide patients with chronic otitis media and/or cholesteatoma specific information about postoperative hearing outcome, based on their level of preoperative ossicular chain damage (OCD). To identify the influence of preoperative OCD on hearing outcomes in patients after chronic otitis media and/or cholesteatoma surgery. PubMed, EMBASE, and the Cochrane Library databases were systematically searched for available evidence, without any constraints, on December 13, 2014, for articles published between January 1, 1975, and December 13, 2014. We reviewed the literature for articles assessing the prognostic value of OCD on postoperative hearing outcome (air-bone gap [ABG] in decibels), using Austin-Kartush criteria or independent OCD classification systems. We assessed relevance and validity using a self-designed critical appraisal tool based on the Cochrane Collaboration's risk of bias tool. Characteristics of study populations and postoperative ABGs in decibels were extracted from all included studies by 4 authors (E.F.B., M.N.G., N.J.K., A.S.H.J.L.). The tested hypothesis was formulated before data collection. Primary study outcome was defined as postoperative adult hearing outcomes after COM and/or cholesteatoma surgery defined as mean postoperative ABG. Our search yielded 5661 articles. Nine articles with high relevance were included. Pooled results of studies using the Austin-Kartush criteria showed a significant (P influence of stapes structure (intact stapes suprastructure, 13.5 [95% CI, 10.3-16.7], 15.1 [95% CI, 11.8-18.3], and 21.9 [95% CI, 15.0-28.8] dB vs absent stapes structure, 12.8 [95% CI, 9.5-16.1], 19.5 [95% CI, 14.9-24.1], and 30.2 [95% CI, 24.7-35.8] dB) on postoperative ABG. One study reported a significant (P = .04) difference in mean ABG between patients with present (18.9 [95% CI, 15.7-22.1] dB) and absent (24.4 [95% CI, 20.2-28.6] dB) malleus. Pooled results of Austin-Kartush studies showed that in

    Successful medical management of otitis externa requires attention to all of the following points: 1. Diagnose and treat systemic or underlying disease(s). 2. Carefully clean and examine the entire ear canal before starting therapy. This includes removal of foreign bodies, parasites, hair, and other obstructions. 3. Apply carefully chosen topical preparations based on gross and microscopic examination. 4. Educate clients as to the causes of the otitis externa and their role in treating the disease. 5. Schedule regular follow-up examinations until the disease is completely cured. 6. Recommend preventive procedures such as drying ears after swimming, corrective surgery, and so on. 7. Use systemic treatment when indicated by chronicity of disease or the owner's inability to treat the patient.

    This study identifies the most significant readability factors and examines ways of improving and evaluating Japanese health information text in terms of ease of reading and understanding. Six different Japanese texts were prepared based on an original short text written by a medical doctor for a hospital web site intended for laypersons regarding chronic suppurative otitis media. Four were revised for single readability factor (syntax, vocabulary, or text structure) and two were modified in all three factors. Using a web-based survey, 270 high school students read one of the seven texts, including the original, completed two kinds of comprehension tests, and answered questions on their impressions of the text's readability. Significantly higher comprehension test scores were shown in the true or false test for a mixed text that presented important information first for better text structure. They were also found in the cloze test for a text using common vocabulary and a cohesive mixed text. Vocabulary could be a critical single readability factor when presumably combined with better text structure. Using multiple evaluation methods can help assess comprehensive readability. The findings on improvement and evaluation methods of readability can be applied to support effective health communication. © 2013 The authors.

    The 5S model proposes five hierarchical levels (systems, summaries, synopses, syntheses and studies) of pre-appraised evidence to guide evidence-based practice. This review aimed to identify and summarise pre-appraised evidence at the highest available 5S level for the management of different subsets of otitis media: acute otitis media, otitis media with effusion, chronic suppurative otitis media and cholesteatoma in both adults and children. Data sources were pre-appraised evidence resources. Evidence freely available from sources at the highest available level of the 5S model were summarised for this review. System level evidence exists for acute otitis media and otitis media with effusion. Summary level evidence exists for recurrent acute otitis media and medical management of chronic suppurative otitis media. There is an absence of randomised controlled trials to prove the efficacy of surgical management of chronic suppurative otitis media and cholesteatoma. Until randomised controlled trial data are generated, consensus publications on the surgical management of chronic suppurative otitis media and cholesteatoma should be used to guide best practice.

    A multicentre double-blind randomized study was carried out to compare topical ciprofloxacin and topical gentamicin in the treatment of simple non-cholesteatomatous purulent chronic otitis media. Three hundred and eight patients were included in the study, 159 treated with ciprofloxacin and 149 treated with gentamicin. The percentage of clinical success (elimination of otorrhoea) was 95% with ciprofloxacin and 94% with gentamicin (ns). Likewise, the percentage of bacteriological erradication was 96% with ciprofloxacin and 93% with gentamicin. Both drugs were well tolerated, without changes in the audiometric values. In these patients, topical ciprofloxacin shows the same efficacy as topical gentamicin without any potential ototoxic effect.

    We report the imaging features of three cases of tuberculous otitis media. All three patients underwent temporal bone CT scanning, and in two, additional MRI scanning was performed. The three cases showed soft tissue density in the external auditory canal, and in two, destruction of the trabeculation and internal cortex of the mastoid bone was noted. In two patients with facial palsy, erosion of the facial canal was seen. On MRI, abundant granulomatous tissue was noted in the middle ear cavity and mastoid air cells. In one case, abnormal enhancement of the cochlea, and of the facial and eighth cranial nerve in the internal acoustic canal was seen. Another case showed enhancement of the vestibule and lateral semicircular canal. If radiologic evaluation of chronic otitis media reveals destruction of the tegmen and trabeculation of the mastoid bone, together with abundant granulation tissue and enhancement of the internal ear, tuberculous otitis media may be included in the differential diagnosis

The sessions consisted of 30 sec irradiation directed at the middle ear through the external meatus for a period of 5 days. Positive results were obtained in 45 of the patients with cessation of discharge on the 2nd or 3rd day, and return of hearing by the end of the week. The remission was not permanent in one patient with recurrent otitis media. These observations indicate that the anti-inflammatory effects of helium-neon irradiation constitute an effective treatment modality in children with otitis media. 6 references.

    The aim of this study was to assess the role of virtual otoscopy and 3D ossicular reconstruction in the preoperative assessment of the ossicles in chronic suppurative otitis media. Thirty three patients of chronic suppurative otitis media with conductive deafness (air-bone gap > 35 dB) were included in this prospective study. All patients underwent axial multidetector CT. The axial CT data set was utilized for multiplanar 2D reformations as well as virtual otoscopy (VO) and 3D reconstructions. The imaging findings on these two techniques were read independently by two radiologists with respect to different parts of the ossicular chain by using a three-point scoring system and were compared with surgical findings. Both imaging techniques had comparable accuracy for evaluation of larger ossicular parts. However, for evaluation of stapes superstructure, VO/3D images were more accurate (85.29%) than 2D images (76.97%). Assessment of the lenticular process and incudostapedial joint by HRCT and 2D reformatted images was not reliable (P > 0.1); however, significant correlation (P < 0.001) was present between VO/3D and the operative findings. Virtual otoscopy improves evaluation of the ossicular chain particularly that of smaller structures such as the lenticular process, incudostapedial joint and stapes superstructure which may influence decisions regarding planning of ossiculoplasty.

    The findings of computed tomography (CT) of 89 patients clinically suspected of having otitis media were studied in this work. Such results were compared to clinical diagnosis, otoscopy, surgical findings and previous data. Among the results of our analysis, we studied seven patients with acute otitis media and 83 patients with chronic otitis media. The patients with acute otitis media have undergone CT examinations to evaluate possible spread to central nervous system. The diagnosis of cholesteatoma, its extension and complications were the main indication. for chronic otitis media study. The main findings of the cholesteatomatous otitis were the occupation of the epitympanun, the bony wall destruction and the ossicular chain erosion. The CT demonstrated a great sensibility to diagnose the cholesteatoma. (author) 25 refs., 10 figs.

    Otitis media is the most common disease of childhood, and represents an important health challenge to the 10-15% of children who experience chronic/recurrent middle ear infections. The middle ear undergoes extensive modifications during otitis media, potentially involving changes in the expression of many genes. Expression profiling offers an opportunity to discover novel genes and pathways involved in this common childhood disease. The middle ears of 320 WBxB6 F1 hybrid mice were inoculated with non-typeable Haemophilus influenzae (NTHi) or PBS (sham control). Two independent samples were generated for each time point and condition, from initiation of infection to resolution. RNA was profiled on Affymetrix mouse 430 2.0 whole-genome microarrays. Approximately 8% of the sampled transcripts defined the signature of acute NTHi-induced otitis media across time. Hierarchical clustering of signal intensities revealed several temporal gene clusters. Network and pathway enrichment analysis of these clusters identified sets of genes involved in activation of the innate immune response, negative regulation of immune response, changes in epithelial and stromal cell markers, and the recruitment/function of neutrophils and macrophages. We also identified key transcriptional regulators related to events in otitis media, which likely determine the expression of these gene clusters. A list of otitis media susceptibility genes, derived from genome-wide association and candidate gene studies, was significantly enriched during the early induction phase and the middle re-modeling phase of otitis but not in the resolution phase. Our results further indicate that positive versus negative regulation of inflammatory processes occur with highly similar kinetics during otitis media, underscoring the importance of anti-inflammatory responses in controlling pathogenesis. The results characterize the global gene response during otitis media and identify key signaling and transcription factor

    In order to determine specific differences, we compared the temporal bone CT findings of chronic otitis media (COM) with and without cholesteatoma, focusing on bone change. Between 1997 and 1998, 82 patients (84 cases) underwent temporal bone CT and were shown to have COM, with or without cholesteatoma after mastoidectomy and tympanoplasty. There were 36 cases of COM with cholesteatoma (26 patients, M:F =3D 11:15; age range, 16-61 (mean, 36,2) years), and 58 cases without chlesteatoma (56 patients, M:F =3D 25:31, age range, 15-61 (mean, 36.2) years). The findings of temporal bone CT were analysed at the point of bony changes including erosion and medial displacement of ossicles (malleus, incus, and stapes), erosion or destruction of the scutum, tegmen, facial canal, and lateral semicircular canal, and ballooning of the tympanic cavity and mastoid antrum. In addition, the soft tissue changes seen on temporal bone CT were analyzed at the site of lateral bulging of soft tissue in Prussak's space, perforation of the pars flaccida, tympanic membrane retraction, and tympanosclerosis. We retrospectively compared the findings of temporal bone CT with the surgical findings, and to assess statistical significance, the Chi-square test was used. Bone erosion or destruction was seen in 36.2% of COM cases without cholesteatoma, and in 96.2% of cases with cholesteatoma. Comparing COM with and without cholesteatoma, the erosion of ossicles including the malleus (81%, 24%), incus (88%, 14%), stapes (58%, 10%), scutum (88%, 10%), facial canal (8%, 0%), and lateral semicircular canal (8%, 0%), was more common in COM with cholesteatoma (p-value less than 0.05), with the exception of erosion of the tegmen (8%, 3%). Other bony changes including medial displacement of ossicles (27%, 3%), ballooning of tympanic cavity and mastoid antrum (96%, 16%), and the soft tissue changes including lateral bulging of soft tissue in Prussak's space (58%, 14%) and perforation of the pars flaccida (35

    To assess the effect of chronic middle ear effusion (CMEE) on balance and equilibrium. Prospective study controlling two groups of children. The active arm consisted of children having a unilateral or bilateral CMEE that persisted for at least 3 months. The control group consisted of children presenting with normal middle ear. Children and parents in both groups were questioned about any symptom of vertigo, dizziness, disequilibrium or child's tendency to fall. ENT exam included an assessment with pneumatic and microscopic otoscopy, evaluation of the vestibular system with the Romberg test, the Fukuda test, the head-shaking test and the Starwalk test. The study group consisted of 15 children (mean = 6.5 years, SD = 2; 10 females and 5 males). The control group consisted also of 15 children (mean = 7.2 years, SD = 1.8; 8 females and 7 males). The duration of MEE was between 3 and 12 months (mean = 8 months). Three children (20%) in the study group had a history of vertigo, imbalance, disequilibrium and/or tendency to fall. None of the children in the control group had such a history (p = 0.22); Five children in the study group had abnormal head-shaking test, Fukuda and/or Starwalk tests (33.33%). Two children in the control group had such a finding (13.33%) (p = 0.39). Romberg test was normal in all children in both groups. In the study group, one child showed positional and spontaneous nystagmus on VNG testing. Another one showed positional nystagmus. Hence, 2 children had abnormal findings on VNG (13.33%). In the control group, VNG was normal in all children (p = 0.46). Tympanometry showed a type B curve in 26 ears, a type C curve in 3 ears and type A in one ear. In the control group all patients presented a type A curve. This paper describes the first study using VNG in a population of children with CMEE. The presence of balance disturbances associated or not with hearing loss is of paramount importance to the clinician as to the indications of myringotomy with a

    Full Text Available Studies relating chronic otitis media and language disorders in children have not reported consistent findings. We carried out the first selective study aimed at discerning the role of chronic right otitis media in children less than 3 years of age in language development. A total of 35 children were studied using a full linguistic protocol, auditory brainstem responses, and middle latency responses. Twelve children had a history of chronic exclusive right otitis media. Seventeen age-matched children were selected as controls. Also, three children having a history of chronic left otitis media were compared with three age-matched controls. Linguistic tests showed significant differences between patients and controls in phonetic, phonological, and syntax scores but not semantics. Correlation studies between linguistic scores and auditory evoked responses in the whole cohort showed a significant coefficient in phonetic and phonological domains. These results emphasize the causative effect of right ear chronic otitis media and indicate that it mainly impairs phonetic and phonological coding of sounds, which may have implications for prophylactic treatment of at-risk children.

    Otitis media represents a major health concern in Australian Indigenous children ('Indigenous children'), which has persisted, despite public health measures, for over 30 years. Global searches were performed to retrieve peer-reviewed and 'grey' literature investigating the epidemiology of and risk factors for otitis media in Indigenous children, published between 1985 and 2012. In Indigenous children, the prevalence of otitis media subtypes is 7.1-12.8 per cent for acute otitis media, 10.5-30.3 per cent for active chronic otitis media and 31-50 per cent for tympanic membrane perforation. The initial onset of otitis media in Indigenous children occurs earlier and persists for longer after the first year of life, compared with non-Indigenous children. Indigenous children are colonised by otopathogens more frequently, at younger ages and with a higher bacterial load. Poor community and domestic infrastructure, overcrowding and exposure to tobacco smoke increase the risk of otitis media in Indigenous children; however, the availability of swimming pools plays no role in the prevention or management of otitis media. Despite awareness of the epidemiological burden of otitis media and its risk factors in Indigenous children, studies undertaken since 1985 demonstrate that otitis media remains a significant public health concern in this population.

    To investigate the clinical role of Vitamin D in prognosis of Otitis media with effusion. This prospective-controlled study was conducted at otolaryngology department in Duzce University, Turkey. The study group comprised children who were diagnosed with Otitis media with effusion between September 2016 and February 2017. Control group was conducted with children underwent circumcision or inguinal hernia repair operations that confirmed with ENT examination they do not have any sign of otitis media. After 3 months of follow-up without any treatment, unresolved cases who were accepted as chronic otitis media with effusion were operated under general anesthesia for ventilation tube application. Study and control groups were assessed depending on the serum 25(OH)Vitamin D levels at the end of 3 months; otitis media with effusion and chronic otitis media with effusion. One-hundred-seventy-four children with otitis media with effusion and 80 control patients were included to the study. One-hundred-eight (62%) out of 174 patients with otitis media with effusion was completely recovered after a 3-months follow up. Of those 66 out of 174 children, they had persistent diseases, underwent ventilation tube insertion after a 3-months follow-up. The mean 25(OH)Vitamin D level was 18.98 ± 10.60 in otitis media with effusion group and 28.07 ± 14.10 in control group and the difference was statistically significant between the study and control group (p otitis media with effusion group whilst 35 out of 108 patients (32.4%) in complete recovery otitis media with effusion group (p = 0.021). The rate of 25(OH)Vitamin D deficiency was 25% in control group which was statistically different from chronic otitis media with effusion and recovery chronic otitis media with effusion groups (p = 0.006). This study not only shows the relationship between Vitamin D and otitis media with effusion development, but also demonstrates the effects of Vitamin D on otitis media with effusion

    The purpose of this study is to introduce and define a disease entity on a continuum of eosinophilic otitis media: eosinophilic mucin otomastoiditis and otopolyposis. A case of a 66-year-old woman with complicated chronic otitis media is reported. A literature review of the National Library of Medicine's online database, with a focus on eosinophilic otitis media and eosinophilic mucin rhinosinusitis, was performed. The authors report the case of a 66-year-old woman with a history of asthma, chronic rhinosinusitis, nasal polyposis, and chronic otitis media who presented with allergic middle ear mucin and otic polyps. Treatment involved a tympanomastoidectomy with removal of otic polyps and steroid therapy. Eosinophilic mucin otomastoiditis with otopolyposis is a disease entity on a continuum of eosinophilic otitis media. This disease process shares similarities with eosinophilic mucin rhinosinusitis. Otic polypectomy and steroids are suggested therapeutic measures. © The Author(s) 2015.

    One in 4 children will have at least 1 episode of acute otitis media (AOM) by age 10 years. AOM results from infection of fluid that has become trapped in the middle ear. The bacteria that most often cause AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Differentiating AOM from otitis media with effusion (OME) is a critical skill for physicians, as accurate diagnosis will guide appropriate treatment of these conditions. Although fluid is present in the middle ear in both conditions, the fluid is not infected in OME as is seen in AOM patients. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available OBJECTIVE: To analyze auditory processing test results in children suffering from otitis media in their first five years of age, considering their age. Furthermore, to classify central auditory processing test findings regarding the hearing skills evaluated. METHODS: A total of 109 students between 8 and 12 years old were divided into three groups. The control group consisted of 40 students from public school without a history of otitis media. Experimental group I consisted of 39 students from public schools and experimental group II consisted of 30 students from private schools; students in both groups suffered from secretory otitis media in their first five years of age and underwent surgery for placement of bilateral ventilation tubes. The individuals underwent complete audiological evaluation and assessment by Auditory Processing tests. RESULTS: The left ear showed significantly worse performance when compared to the right ear in the dichotic digits test and pitch pattern sequence test. The students from the experimental groups showed worse performance when compared to the control group in the dichotic digits test and gaps-in-noise. Children from experimental group I had significantly lower results on the dichotic digits and gaps-in-noise tests compared with experimental group II. The hearing skills that were altered were temporal resolution and figure-ground perception. CONCLUSION: Children who suffered from secretory otitis media in their first five years and who underwent surgery for placement of bilateral ventilation tubes showed worse performance in auditory abilities, and children from public schools had worse results on auditory processing tests compared with students from private schools.

    Computed tomography was performed preoperatively in 20 patients suffering from malignant external otitis. The CT findings were nearly completely confirmed by the intraoperative findings. A circumscribed or diffuse thickening of the cartilaginous wall of the external auditory canal and an inflammatory infiltration of the subtemporal fossa are, in combination, most suspicious signs of malignant external otitis. Computed tomography enabels detailed information on the extension of the pneumatic system and the grade of involvement of bones and soft tissues in malignant external otitis. A modified classification of malignant external otitis based on computed tomographic findings is proposed. (orig.) [de

    Otitis media is a more frequent occurrence in children, and the disease may progress from an acute to chronic state if appropriate and timely intervention is not initiated. A total of 212 children aged 6 months to 10 years were examined and treated for otitis media, in a 13-month hospital-based study. Acute otitis media was diagnosed in 130 (61.3 per cent) of the patients. There were 82 (38.7 per cent) chronic suppurative otitis media cases. The incidence of acute otitis media and chronic suppurative otitis media in the first year of life was 54.6 per cent and 45.1 per cent respectively. Chronic suppurative otitis media patients were assigned to one of three treatment groups. Recovery occurred in 70.4 per cent of amoxicillin-treated patients, in 88.9 per cent of amoxicillin-clavulanic acid treated patients and in 96.4 per cent of culture and antibiotic sensitivity test patients. Relapses were seen only in the amoxicillin (five cases) and amoxicillin-clavulanic acid (two cases) groups. The success rate in patients treated with antibiotics makes this option mandatory for an established diagnosis.

    This paper illustrates the value of CT and MR in early diagnosis and spread of malignant external otitis. The authors retrospectively analyzed 15 patients with proved malignant external otitis examined with postcontrast high-resolution CT (15/15) and MR (6/15) (T1- and T2-weighting). Gallium studies were done in 6/15 patients. Early diagnosis was made when CT demonstrated a soft-tissue mass of the external auditory canal associated with scattered zones of cortical bone erosions (13/15). Spread of the disease was better delineated by MR than CT, especially skull base extension (6/15). Temporomandibular joint involvement with extension into parotid or/and masticator spaces 6/15 was as well detected with CT as with MR. If CT remains the first and best procedure for diagnosis, MR - despite its cost - appears a good procedure to depict exact anatomic spread, allowing therapeutic management

    This study aims to describe parental experiences and perspectives of caring for a child with otitis media. We conducted a systematic review of qualitative studies on parental perspectives on caring for a child with otitis media. We searched electronic databases to July 2015. Seventeen studies involving 284 participants from six countries were included. We identified seven themes: diminishing competency (guilt over failure to identify symptoms, helpless and despairing, fear of complications, disempowered and dismissed); disrupting life schedules (disturbing sleep, interfering with work, burden on family); social isolation (stigma and judgement, sick consciousness); threatening normal development (delaying growth milestones, impairing interpersonal skills, impeding education); taking ownership (recognising symptoms, diagnostic closure, working the system, protecting against physical trauma, contingency planning); valuing support (needing respite, depending on community, clinician validation); and cherishing health (relief with treatment success, inspiring resilience). The additional medical responsibilities and anxieties of parents caring for a child with otitis media, often discounted by clinicians, can be disempowering and disruptive. Chronicity can raise doubt about treatment efficacy and parental competency, and fears regarding their child's development. Care that fosters parental confidence and addresses their concerns about the child's development may improve treatment outcomes for children with otitis media. • Otitis media is a leading cause of conductive hearing loss in children. • Parental perception of the treatment burden of otitis media can potentially affect their confidence and ability to care for their child. What is New: • We identified five themes to reflect parental perspectives: diminishing competency, disrupting life schedules, social isolation, threatening normal development, taking ownership, valuing support, and cherishing health.

    Acute otitis media (AOM) is a common disease of childhood. AOM is most appropriately diagnosed by careful otoscopy with an understanding of clinical signs and symptoms. The distinction between AOM and chronic otitis media with effusion should be emphasized. Treatment should include pain management, and initial antibiotic treatment should be given to those most likely to benefit, including young children, children with severe symptoms, and those with otorrhea and/or bilateral AOM. Tympanostomy tube placement may be helpful for those who experience frequent episodes of AOM or fail medical therapy. Recent practice guidelines may assist the clinician with such decisions.

    Otitis media is the most common infection second only to viral upper respiratory infection in the outpatient setting. Tympanostomy tube insertion (TTI) is the most common ambulatory surgical procedure in the United States. While many risk factors for otitis media have been identified, atopic conditions have been under-recognized as risk factors for recurrent and persistent otitis media. Given that asthma and other atopic conditions are the most common chronic conditions during childhood, it is worth examining the association between atopic conditions and risk of otitis media, which can provide insight into how atopic conditions influence the risk of microbial infections. This paper focuses its discussion on otitis media, however it is important that the association between atopic conditions and risk of otitis media be interpreted in the context of the association of atopic conditions with increased risks of various microbial infections.

    Eosinophilic otitis media (EOM) is a relatively rare, intractable, middle ear disease with extremely viscous mucoid effusion containing eosinophils. EOM is associated with adult bronchial asthma and nasal allergies. Conventional treatments for otitis media with effusion (OME) or for chronic otitis media (COM), like tympanoplasty or mastoidectomy, when performed for the treatment of EOM, can induce severe complications such as deafness. Therefore, it should be differentiated from the usual type of OME or COM. To our knowledge, the clinical and imaging findings of EOM of temporal bone are not well-known to radiologists. We report here the CT and MRI findings of two EOM cases and review the clinical and histopathologic findings of this recently described disease entity.

    Purpose: To assess the role of three-dimensional volume rendering (3DVR) in the preoperative assessment of the ossicular chain in chronic suppurative otitis media (CSOM). Materials and methods: Sixty-six patients with CSOM were included in this prospective study. Temporal bone was scanned with a 128-channel multidetector row CT and the axial data was transferred to the workstation for multiplanar reformation (MPR) and 3DVR reconstructions. Evaluation of the ossicular chain according to a three-point scoring system on two-dimensional reformation (2D) and 3DVR was performed independently by two radiologists. The evaluation results were compared with surgical findings. Results: 2D showed over 89% accuracy in the assessment of segmental absence of the ossicular chain in CSOM, no matter how small the segmental size was. 3DVR was as accurate as 2D for the assessment of segmental absence. However, 3DVR was found to be more accurate than 2D in the evaluation of partial erosion of segments. Conclusion: Both 3DVR and 2D are accurate and reliable for the assessment of the ossicular chain in CSOM. The inclusion of 3DVR images in the imaging protocol improves the accuracy of 2D in detecting ossicular erosion from CSOM

    The function of the Eustachian tube plays a significant role in increased risk chronic suppurative otitis media (CSOM). The angle of the Eustachian tube is a predisposing factor for Eustachian tube dysfunction and clearance disorder of the middle ear. The aim of this study was to compare the mean angle of a Eustachian tube of CSOM ears and normal ears. This research was a cross-sectional study consisting of 19 patients of CSOM without cholesteatoma, 19 patients of CSOM with cholesteatoma and 19 patients with normal ears. All patients were examined using CT Temporal, and the angle of the eustachian tube was measured using multiplanar reconstruction technique. The mean angle of Eustachian tube in CSOM patients without cholesteatoma was 32.82° (SD=3.82), in CSOM with cholesteatoma was 27.74° (SD=4.44) and in normal ears was 33.61° (SD=3.83). Based on Kruskal-Wallis test, there was a significant difference in the angle of a Eustachian tube of these three groups (p<0.001). There was a significant difference between the mean angle of the Eustachian tube in CSOM ears and normal ears.

    Full Text Available ABSTRACT Introduction: Otitis media is an inflammation of part or all of the mucosa of the middle ear, Eustachian tube, mastoid antrum, and mastoid cells. Patients with middle ear disease often comes as a chronic stage that causes hearing loss and expense secretions. Patients complain of hearing loss that disrupt the function of the social, educational and professional. School-age children may show poor results at school. One type of otitis media is chronic suppurative otitis media (CSOM, which is a chronic infection of the middle ear with tympanic membrane perforation and discharge of secretions from the middle ear continuous or intermittent, usually accompanied by hearing loss. Secretions may be thin or thick, clear or in the form of pus. CSOM formerly called otitis media with perforated. Diagnosis is made by history, physical examination. Two types of classification that is often used is CSOM types of benign and malignant types, and based on the activity of secretions out. Management of sudden deafness include conservative with some medical therapy depends on the type of CSOM and accompanying complications. Case: Male patient, 47 years old, came with complaints of discharge from the left ear since 1 month ago. Discharge yellowish-white, slightly viscous, odorless, out a little, and not itchy. Patients with a history of diabetes. Patients admitted before the water could get into the ear while swimming in the sea. At the present status and status generalist within normal limits. On the left ear found mucopurulent secretions. On the left tympanic membrane perforation in the visible region of the central part postero superior. Keywords:otitis, chronic, ear.

    Full Text Available Malignant otitis externa (MOE is an aggressive but benign entity which evolves into skull base osteomyelitis. An 81-year-old female patient was admitted for left hemiparesis and homonymous hemianopia. She complained of headache radiating to the right cervical area. A recent history of recurrent otitis media was present. Head and neck imaging showed an ischemic infarction (right temporo-occipital and a parapharyngeal soft tissue mass originating in an external and medial ear infection. Culture samples revealed Pseudomonas aeruginosa infection leading to the diagnosis of Malignant otitis externa (MOE. Parenteral antibacterial therapy and hyperbaric oxygen therapy resulted in improvement.

    To identify genetic and environmental risk factors for otitis media in an indigenous Filipino population. Cross-sectional study. Indigenous Filipino community. Clinical history and information on breastfeeding, tobacco smoke exposure, and swimming were obtained from community members. Heads of households were interviewed for family history and personal beliefs on ear health. Height and weight were measured. Otoscopic findings were described for the presence and character of perforation or discharge. An A2ML1 duplication variant that confers otitis media susceptibility was Sanger sequenced in all DNA samples. Co-occurrence of middle ear bacteria detected by 16S rRNA gene sequencing was determined according to A2ML1 genotype and social cluster. The indigenous Filipino population has a ~50% prevalence of otitis media. Young age was associated with otitis media (4 age strata; P = .004); however, age was nonsignificant as a bistratal or continuous variable. There was no association between otitis media and sex, body mass index, breastfeeding, tobacco exposure, or deep swimming. In multivariate analyses, A2ML1 genotype is the strongest predictor of otitis media, with an odds ratio of 3.7 (95% confidence interval: 1.3-10.8; P = .005). When otitis media diagnoses were plotted across ages, otitis media was observed within the first year of life, and chronic otitis media persisted up to adulthood, particularly in A2ML1-variant carriers. Among indigenous Filipinos, A2ML1 genotype is the primary risk factor for otitis media and main determinant of disease progression, although age, the middle ear microbiome, and social clusters might modulate the effect of the A2ML1 genotype. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Accurate diagnosis of otitis media is important to prevent suffering and complications when infection is present, and unnecessary antibiotic use when infection is absent. The usual signs and symptoms of acute otitis media are unreliable guides in infants and young children. Similarly, middle ear effusions may present with little discomfort in older children. We therefore depend on examination of the tympanic membrane with an otoscope to make most diagnoses. This article aims to improve the accuracy of middle ear diagnosis by pneumatic otoscopy. It includes descriptions and photographs of the normal ear drum and illustrates the pathologic changes seen in acute otitis media, long-standing eustachian tube dysfunction and otitis media with effusion.

    Malignant external otitis is an aggressive infection caused by Pseudomonas aeruginosa that most often occurs in elderly diabetics. Malignant external otitis often spreads inferiorly from the external canal to involve the subtemporal area and progresses medially towards the petrous apex leading to multiple cranial nerve palsies. The computed tomographic (CT) findings in malignant external otitis include obliteration of the normal fat planes in the subtemporal area as well as patchy destruction of the bony cortex of the mastoid. The point of exit of the various cranial nerves can be identified on CT scans, and the extent of the inflammatory mass correlates well with the clinical findings. Four cases of malignant external otitis are presented. In each case CT provided a good demonstration of involvement of the soft tissues at the base of the skull

    Acute otitis media is a common childhood infection. Prompt diagnosis and appropriate treatment are very important. To review in depth the epidemiology, pathophysiology, clinical manifestations, diagnosis, complications and particularly treatment of acute otitis media in children. A PubMed search was completed in Clinical Queries using the key term "acute otitis media". Patents were searched using the key term "acute otitis media" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com. Acute otitis media affects over 80% of children before their third birthday and 30 to 45% of these children have suffered two or more episodes. Streptococcus pneumoniae, nontypable Haemophilus influenzae, and Moraxella catarrhalis are the most frequently isolated middle-ear pathogens. The diagnosis is based on acute onset of symptoms such as otalgia and fever, middle ear inflammation such as erythema of the tympanic membrane, and middle ear effusion. The choice of treatment method depends on the age of the child, laterality, and the severity of the disease. Recent patents related to the management of acute otitis media are also retrieved and discussed. Antimicrobial treatment is recommended for all children less than two years of age, as well as in children ≥ two years of age who have a temperature ≥ 39oC; are toxic looking; have otalgia > 48 hours; have bilateral otitis media or otorrhea; have craniofacial abnormalities; are immunocompromised; or have uncertain access to follow-up. Amoxicillin is the drug of choice. Observation without antibiotic is an option in immunocompetent children ≥ two years of age who have an acute uncomplicated otitis media and non-severe illness if appropriate follow-up can be arranged.

    Although the epidemiology of otitis media is well-known in industrialized countries, the extent of otitis media in developing Asian countries, especially in south East Asia is not well studied. To define the burden of otitis media and its sequelae in children 6-15 years of age, we enrolled elementary and junior high school children in 6 areas in rural and urban Indonesia. Randomly selected schools and classrooms were selected. All children were administered a questionnaire and had ear examinations, pneumatic otoscopy and screening audiometry. Children with any abnormality on examination or with a relevant history underwent diagnostic audiometry and tympanometry, if indicated. Of the 7005 children studied, 116 had chronic suppurative otitis media (CSOM), 30 had acute otitis media and 26 had otitis media with effusion. 2.7% of rural children had CSOM compared with 0.7% of urban children (P < 0.0001). The rates per 1000 of CSOM in rural Bali and Bandung were significantly higher (75 and 25, respectively) than in the rest of Indonesia (P < 0.05). In rural Bali, the rate per 1000 children of inactive CSOM was 63 in 6- to 9-year-old children, compared with 37 in children aged 13-15 years. Concomitantly, the rates of tympanosclerosis were 7 and 26/1000, respectively, in these age groups. In Indonesia, the prevalence of CSOM is relatively high with most disease occurring in rural areas. The high rates in rural Bali with early progression to tympanosclerosis suggest a significant burden of potentially vaccine preventable illness.

    The objective of the study was to examine the association between otitis media in childhood and dizziness in adulthood. Longitudinal, population-based cohort study of 21,962 adults (aged 20-59 years, mean 40) who completed a health questionnaire in the Nord-Trøndelag Hearing Loss Study was conducted. At 7, 10 and 13 years of age, the same individuals underwent screening audiometry in a longitudinal school hearing investigation. Children found with hearing loss underwent an ear, nose and throat specialist examination. Adults diagnosed with childhood chronic suppurative otitis media (n = 102) and childhood hearing loss after recurrent acute otitis media (n = 590) were significantly more likely to have increased risk of reported dizziness when compared to adults with normal hearing as children at the school investigation and also a negative history of recurrent otitis media (n = 21,270), p otitis media and childhood hearing loss after recurrent acute otitis media are associated with increased risk of dizziness in adulthood. This might reflect a permanent effect of inflammatory mediators or toxins on the vestibular system. The new finding stresses the importance of treatment and prevention of these otitis media conditions.

    Otitis media (OM), as a common infectious disease, is a major cause of hearing impairment among the general population. OM remains a major public health threat in the Pacific islands, but the risks of OM have not been thoroughly explored in this region. The objective of this study is to investigate the prevalence, clinical features, and quality-of-life impacts of OM in Fiji. In the medical service trip entitled "Healing and Hope - Taiwan Cathay Heart and Hearing Medical Mission to Fiji" (TCHHMMF), we conducted a cross-sectional OM survey study in Suva and Sigatoka areas (Korolevu, Cuvu, and Lomawai) in the summer of 2015. The otitis media - 6 (OM-6) was used to survey the OM-related quality of life. In the 467 pediatric patients (aged 0-18 years old) screened, 13 (2.78%) have acute otitis media (AOM), 37 (7.92%) have otitis media with effusion (OME), and 19 (4.1%) have chronic otitis media (COM). Age (OR 0.53, 95% CI: 0.36-0.77) is a significant predictor of AOM, whereas male gender (OR 2.46, 95% CI: 1.13-5.37), smoke exposure (OR 2.81, 95% CI: 1.01-7.82), and concomitant chronic sinusitis (OR 6.05, 95% CI: 2.31-15.88) are significant predictors of OME. The mean OM-6 item scores are highest in caregiver concerns (3.8), physical suffering (3.7), and hearing loss (3.4) domains. OM is an important primary care disease in Fiji that remains under-served. It is critical to educate professionals, parents, and patients to detect and to improve care for OM. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  9. Intracellular Secretory Leukoprotease Inhibitor Modulates Inositol 1,4,5-Triphosphate Generation and Exerts an Anti-Inflammatory Effect on Neutrophils of Individuals with Cystic Fibrosis and Chronic Obstructive Pulmonary Disease

    2013-01-01

    Full Text Available Secretory leukoprotease inhibitor (SLPI is an anti-inflammatory protein present in respiratory secretions. Whilst epithelial cell SLPI is extensively studied, neutrophil associated SLPI is poorly characterised. Neutrophil function including chemotaxis and degranulation of proteolytic enzymes involves changes in cytosolic calcium (Ca2+ levels which is mediated by production of inositol 1,4,5-triphosphate (IP3 in response to G-protein-coupled receptor (GPCR stimuli. The aim of this study was to investigate the intracellular function of SLPI and the mechanism-based modulation of neutrophil function by this antiprotease. Neutrophils were isolated from healthy controls (n=10, individuals with cystic fibrosis (CF (n=5 or chronic obstructive pulmonary disease (COPD (n=5. Recombinant human SLPI significantly inhibited fMet-Leu-Phe (fMLP and interleukin(IL-8 induced neutrophil chemotaxis (P<0.05 and decreased degranulation of matrix metalloprotease-9 (MMP-9, hCAP-18, and myeloperoxidase (MPO (P<0.05. The mechanism of inhibition involved modulation of cytosolic IP3 production and downstream Ca2+ flux. The described attenuation of Ca2+ flux was overcome by inclusion of exogenous IP3 in electropermeabilized cells. Inhibition of IP3 generation and Ca2+ flux by SLPI may represent a novel anti-inflammatory mechanism, thus strengthening the attractiveness of SLPI as a potential therapeutic molecule in inflammatory airway disease associated with excessive neutrophil influx including CF, non-CF bronchiectasis, and COPD.

    The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

    Otitis media is one of the most common diseases in small children. This underlines the importance of optimizing diagnostics and treatment of the condition. Recent literature points toward a stricter approach to diagnosing acute otitis media (AOM). Moreover, ventilating tube treatment for recurrent AOM (RAOM) and chronic otitis media with effusion (COME) has become the most frequently performed surgical procedure in pre-school children. Therefore, the Danish Health and Medicines Authority and the Danish Society of Otorhinolaryngology, Head and Neck Surgery deemed it necessary to update the Danish guidelines regarding the diagnostic criteria for acute otitis media and surgical treatment of RAOM and COME. The GRADE system (The Grading of Recommendations Assessment, Development and Evaluation) was used in order to comply with current standards of evidence assessment in formulation of recommendations. An extensive literature search was conducted between July and December 2014. The quality of the existing literature was assessed using AGREE II (Appraisal of Guidelines for Research & Evaluation), AMSTAR (assessing the Methodological Quality of Systematic Reviews), QUADAS-2 (Quality of Diagnostic Accuracy Studies), Cochrane Risk of Bias Tool for randomized trials and ACROBAT-NRSI (A Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies). The working group consisted of otolaryngologists, general practitioners, pediatricians, microbiologists and epidemiologists. Recommendations for AOM diagnosis, surgical management for RAOM and COME, including the role of adenoidectomy and treatment of ventilating tube otorrhea, are proposed in the guideline.

    2016-04-01

    Full Text Available Background :  Otitis Media with Effusion(OME also known as  Secretory Otitis Media, has been identified as the commonest middle ear condition causing deafness in children in developed countries. Neither the indication for surgical treatment nor the types and number of procedures used are uniform. Possible treatment includes myringotomy with or without insertion of ventilation tube either alone or with adenoidectomy and occasionally tonsillectomy. Aims and Objectives :  To assess the prevalence and the different modes of presentation of Otitis Media with Effusion among the rural school children of Puducherry and to assess the improvement in hearing after 6 months of surgical intervention done on patients with Otitis Media with Effusion. Materials and Methods:  A school screening camp was conducted on 600 children in the age group of 5-12 years in a government middle school near our medical college hospital for identifying children with Otitis Media with Effusion. Students with Otitis Media with Effusion were further classified into 4 groups for various interventional procedures namely adenotonsillectomy with bilateral grommet insertion (Group A, adenoidectomy with bilateral grommet insertion (Group B, bilateral grommet insertion (Group C,  bilateral myringotomy with wide field incision in the antero-inferior quadrant (Group D. Result : The prevalence was almost in equal proportions in the age group between 5-12 years and the overall prevalence of Otitis Media with Effusion among the study population was 13.3%. The adenotonsillectomy with bilateral grommet insertion procedure had shown a significant improvement in hearing, which was measured by using pure tone audiometry by assessing the mean air-bone gap, which was 9.81, 8.27 and 6.73 at the end of 6 weeks, 3 months and 6 months respectively, when compared to the other procedures.   Conclusion : Adenotonsillectomy with bilateral grommet insertion should be considered in a child with Otitis

    Moraxella (Branhaomella) catarrhalis is frequently present in the nasopharyngeal microflora of small children, especially during episodes of acute otitis media . By means of ribotyping (restriction endonuclease analysis of chromosomal DNA combined with rRNA probing), we studied the genetic...... heterogeneity of 78 cultures of M. catarrhalis obtained from different localities in the nasopharynx of nine young children with secretory otitis media. Using HindIII and PstI as endonucleases, five different ribotypes were recognized, representing at least five different genotypes of M. catarrhalis....... The distribution of these types was found to be almost identical to the distribution among 16 M. catarrhalis strains cultured from middle ear exudates of 16 children with acute otitis media. Ribotype HAPA was found in two-thirds of all the cultures investigated, and 44% of the children harboured more than one...

    Tuberculosis is a global health problem that is especially prevalent in developing countries such as India. Recently, atypical presentation has become more common and a high index of suspicion is essential. This study analysed the various presenting symptoms and signs of tuberculous otitis media and the role of diagnostic tests, with the aim of formulating criteria for the diagnosis. A total of 502 patients underwent tympanomastoidectomy over a two-year period. Microbiological and histopathological examinations and polymerase chain reaction analysis of tissue taken during tympanomastoidectomy were performed. A total of 25 patients (5 per cent) were diagnosed with tuberculous otitis media. Severe mixed hearing loss, facial palsy, labyrinthine fistula, post-aural fistula, perichondritis and extradural abscess were noted. There seems to be a resurgence in tuberculous otitis media in India. Microbiological, histopathological and polymerase chain reaction tests for tuberculosis are helpful for its diagnosis.

    Technetium99 Methylene Diphosphate bone scanning has been considered an early valuable tool to diagnose necrotizing progressive malignant external otitis. However, to our knowledge, no formal studies have actually compared bone scans of otherwise young, healthy patients with severe external otitis to scans of patients with clinical presentation of malignant external otitis. Twelve patients with only severe external otitis were studied with Technetium99 Diphosphate and were compared to known cases of malignant otitis. All scans were evaluated by two neuroradiologists with no prior knowledge of the clinical status of the patients. Nine of the 12 patients had positive bone scans with many scans resembling those reported with malignant external otitis. Interestingly, there was no consistent correlation between the severity of clinical presentation and the amount of Technetium uptake. These findings suggest that a positive bone scan alone should not be interpreted as indicative of malignant external otitis

  19. Chronic Insulin Exposure Induces ER Stress and Lipid Body Accumulation in Mast Cells at the Expense of Their Secretory Degranulation Response.

    Directory of Open Access Journals (Sweden)

    William E Greineisen

    Full Text Available Lipid bodies (LB are reservoirs of precursors to inflammatory lipid mediators in immunocytes, including mast cells. LB numbers are dynamic, increasing dramatically under conditions of immunological challenge. We have previously shown in vitro that insulin-influenced lipogenic pathways induce LB biogenesis in mast cells, with their numbers attaining steatosis-like levels. Here, we demonstrate that in vivo hyperinsulinemia resulting from high fat diet is associated with LB accumulation in murine mast cells and basophils. We characterize the lipidome of purified insulin-induced LB, and the shifts in the whole cell lipid landscape in LB that are associated with their accumulation, in both model (RBL2H3 and primary mast cells. Lipidomic analysis suggests a gain of function associated with LB accumulation, in terms of elevated levels of eicosanoid precursors that translate to enhanced antigen-induced LTC4 release. Loss-of-function in terms of a suppressed degranulation response was also associated with LB accumulation, as were ER reprogramming and ER stress, analogous to observations in the obese hepatocyte and adipocyte. Taken together, these data suggest that chronic insulin elevation drives mast cell LB enrichment in vitro and in vivo, with associated effects on the cellular lipidome, ER status and pro-inflammatory responses.

    The hypothalamic-pituitary-adrenal (HPA) axis is a psychoneuroendocrine regulator of the stress response and immune system, and dysfunctions have been associated with outcomes in several physical health conditions. Its end product, cortisol, is relevant to fatigue due to its role in energy metabolism. The systematic review examined the relationship between different markers of unstimulated salivary cortisol activity in everyday life in chronic fatigue syndrome (CFS) and fatigue assessed in other clinical and general populations. Search terms for the review related to salivary cortisol assessments, everyday life contexts, and fatigue. All eligible studies (n=19) were reviewed narratively in terms of associations between fatigue and assessed cortisol markers, including the cortisol awakening response (CAR), circadian profile (CP) output, and diurnal cortisol slope (DCS). Subset meta-analyses were conducted of case-control CFS studies examining group differences in three cortisol outcomes: CAR output; CAR increase; and CP output. Meta-analyses revealed an attenuation of the CAR increase within CFS compared to controls (d=-.34) but no statistically significant differences between groups for other markers. In the narrative review, total cortisol output (CAR or CP) was rarely associated with fatigue in any population; CAR increase and DCS were most relevant. Outcomes reflecting within-day change in cortisol levels (CAR increase; DCS) may be the most relevant to fatigue experience, and future research in this area should report at least one such marker. Results should be considered with caution due to heterogeneity in one meta-analysis and the small number of studies. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Determine if a 2-Step multivariate analysis of historical symptom/sign data for comorbid diseases can abstract high-level constructs useful in assigning a child's "risk" for different Otitis Media expressions. Seventeen items related to the symptom/sign expression of hypothesized Otitis Media comorbidities were collected by history on 141 3-year-old children. Using established criteria, the children were assigned to 1 of 3 groups: Control (no significant past Otitis Media, n=45), Chronic Otitis Media with Effusion (n=45) and Recurrent Acute Otitis Media (n=51). Principal Component Analysis was used to identify factors representing the non-redundant shared information among related items and Discriminant Analysis operating on those factors was used to estimate the best predictor equation for pairwise group assignments. Six multivariate factors representing the assignable comorbidities of frequent colds, nasal allergy, gastroesophageal disease (specific and general), nasal congestion and asthma were identified and explained 81% of the variance in the 17 items. Discriminant Analysis showed that, for the Control-Chronic Otitis Media with Effusion comparison, a combination of 3 factors and, for the Control-Recurrent Acute Otitis Media comparison, a combination of 2 factors had assignment accuracies of 74% and 68%, respectively. For the contrast between the two disease expressions, a 2-factor combination had an assignment accuracy of 61%. These results show that this analytic methodology can abstract high-level constructs, comorbidities, from low-level data, symptom/sign scores, support a linkage between certain comorbidities and Otitis Media risk and suggest that specific comorbidity combinations contain information relevant to assigning the risk for different Otitis Media expressions.

  3. Pathogenesis of otitis externa and otitis media in dogs and cats

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Diseases of the outer and middle ear (Otitis externa and Otitis media are a frequent clinical problem which is mostly approached in the wrong way. We believe that the approach to a diseased ear in dogs or cats by practicing veterinarians in our country is most often incorrect. Namely, the conventional approach to inflammation of the outer ear is narrowed down to cleaning the ear, usually with cotton wool and hydrogen peroxide, and then by applying ear drops for veterinary or human use over the next few days. A somewhat more conscientious approach implies treatment using antibiotics, topical and/or systemic, but based on an antibiogram. If the presence of a foreign body is suspected, the veterinarian will use an otoscope, and this is where the entire diagnostic approach in our conditions usually ends. Such procedures most often fail to resolve the problem, so that the disease recurs after a certain time or becomes chronic recurrent Otitis externa, which is one of the biggest problems in dog dermatology. Experience shows that veterinarians here are generally not familiar with the pathogenesis of outer and middle ear infection, and that this is the reason why they approach diagnostics and therapy in the wrong way. The most important thing is to have in mind that bacteria and fungi linked with a pathological process in the ear canal are merely opportunistic microorganisms, and never primary pathogens, themselves responsible for Otitis externa. Antibiotic or antimycotic treatment does not cure the basic disease which led to the inflammation, but only its consequences. A large number of factors involved in the inflammation of the outer or middle ear are traditionally divided into primary, predisposing, secondary, and underlying. The basis for the successful treatment of Otitis externa and Otitis media is the recognition, elimination or control of the primary factors (atopy, nutritive allergy, keratinization disorders, parasitic infestations.

    Bacterial resistance in acute otitis can result in bacterial persistence and biofilm formation, triggering chronic and recurrent infections. To investigate the middle ear inflammatory response to bacterial infection in human and chinchilla temporal bones. Six chinchillas underwent intrabullar inoculations with 0.5 mL of 106 colony-forming units (CFUs) of Streptococcus pneumoniae, serotype 2. Two days later, we counted bacteria in middle ear effusions postmortem. One ear from each chinchilla was processed in paraffin and sectioned at 5 µm. The opposite ear was embedded in epoxy resin, sectioned at a thickness of 1 µm, and stained with toluidine blue. In addition, we examined human temporal bones from 2 deceased donors with clinical histories of otitis media (1 with acute onset otitis media, 1 with recurrent infection). Temporal bones had been previously removed at autopsy, processed, embedded in celloidin, and cut at a thickness of 20 µm. Sections of temporal bones from both chinchillas and humans were stained with hematoxylin-eosin and immunolabeled with antifibrin and antihistone H4 antibodies. Histopatological and imminohistochemical changes owing to otitis media. Bacterial counts in chinchilla middle ear effusions 2 days after inoculation were approximately 2 logs above initial inoculum counts. Both human and chinchilla middle ear effusions contained bacteria embedded in a fibrous matrix. Some fibers in the matrix showed positive staining with antifibrin antibody, others with antihistone H4 antibody. In acute and recurrent otitis media, fibrin and neutrophil extracellular traps (NETs) are part of the host inflammatory response to bacterial infection. In the early stages of otitis media the host defense system uses fibrin to entrap bacteria, and NETs function to eliminate bacteria. In chronic otitis media, fibrin and NETs appear to persist.

    Objective: Acute otitis media (AOM) causes an inflammatory response in the middle ear. We assessed differences in innate immune responses involved in bacterial defense at onset of AOM in children who were stringently defined as otitis prone (sOP) and children not otitis prone (NOP). Study Design: Innate immune genes analysis from middle ear fluid (MEF) samples of children. Methods: Genes of toll-like receptors (TLR), nod-like and retinoic acid-inducible gene-I-like receptors, downstream effectors important for inflammation and apoptosis, including cytokines and chemokines, were studied from MEF samples by using a real-time polymerase chain reaction array. Protein levels of differentially regulated genes were measured by Luminex. Results: Gene expression in MEF among children who were sOP was significantly different in upregulation of interleukin 8, secretory leukocyte peptidase inhibitor, and chemokine (C-C motif) ligand 3, and in downregulation of interferon regulatory factor 7 and its related signaling molecules interferon alpha, Toll-like receptor adaptor molecule 2, chemokine (C-C motif) ligand 5, and mitogen-activated protein kinase 8 compared with children who were NOP. Differences in innate gene regulation were similar when AOM was caused by Streptococcus pneumoniae or nontypeable Haemophilus influenzae. Conclusion: Innate-immune response genes are differentially regulated in children who were sOP compared with children with NOP. PMID:28124644

    Our study aimed to evaluate pathologic changes in the cochlear (inner and outer hair cells and stria vascularis) and vestibular (vestibular hair cells, dark, and transitional cells) sensorial elements in temporal bones from donors who had otitis media. We studied 40 temporal bones from such donors, which were categorized in serous otitis media (SOM), serous-purulent otitis media (SPOM), mucoid/mucoid-purulent otitis media (MOM/MPOM), and chronic otitis media (COM); control group comprised 10 nondiseased temporal bones. We found significant loss of inner and outer cochlear hair cells in the basal turn of the SPOM, MOM/MPOM and COM groups; significant loss of vestibular hair cells was observed in the MOM/MPOM and COM groups. All otitis media groups had smaller mean area of the stria vascularis in the basal turn of the cochlea when compared to controls. In conclusion, our study demonstrated more severe pathologic changes in the later stages of the continuum of otitis media (MOM/MPOM and COM). Those changes seem to progress from the basal turn of the cochlea (stria vascularis, then inner and outer hair cells) to the middle turn of the cochlea and to the saccule and utricle in the MOM/MPOM and COM stages.

    Acute otitis media occurs as a complication of viral upper respiratory tract infection. Bacterial otopathogens and respiratory viruses interact and play important roles in acute otitis media development. A better understanding of viral and bacterial interactions may lead to innovative ways to lessen the burden of this common childhood disease. There has been increasing evidence that acute otitis media occurs during upper respiratory infection, even in the absence of nasopharyngeal bacterial colonization. Among the types of viruses associated with acute otitis media, respiratory syncytial virus continues to be the most commonly detected. It is still unclear whether viral load plays an important role in acute otitis media development, but symptomatic upper respiratory tract infection (as opposed to asymptomatic viral infection) is crucial. Widespread use of bacterial and viral vaccines in young children, including pneumococcal conjugate and influenza vaccines, has led to the reduction in otitis media-related healthcare use between 2001 and 2011. There has been no new vaccine against respiratory viruses other than influenza. Progress has been made toward the reduction of the burden of acute otitis media in the last decade. Success in reducing acute otitis media incidence will rely mainly on prevention of nasopharyngeal otopathogen colonization, as well as reduction in the incidence of viral upper respiratory tract infection.

    Otitis media typically presents as either acute otitis media (AOM), with symptoms including fever, otalgia, otorrhoea or irritability and short duration; or as otitis media with effusion (OME), which is often asymptomatic and characterised by accumulation of fluid in the middle ear. Diagnostic certainty of otitis media is challenging, given the young age of patients and variability of symptoms. Otitis media predominantly occurs as coincident to viral upper respiratory tract infections and/or bacterial infections. Common viruses that cause upper respiratory tract infection are frequently associated with AOM and new-onset OME. These include respiratory syncytial virus, rhinovirus, adenovirus, parainfluenza and coronavirus. Predominant bacteria that cause otitis media are Streptococcus pneumoniae, Moraxella catarrhalis, and non-typeable Haemophilus influenzae. Antibiotic therapy does not significantly benefit most patients with AOM, but long-term prophylactic antibiotic therapy can reduce the risk of otitis media recurrence among children at high risk. In Australia, 84% of AOM is treated with antibiotic therapy, which contributes to development of antibiotic resistance. Vaccine development is a key future direction for reducing the world burden of otitis media, but requires polymicrobial formulation and ongoing monitoring and modification to ensure sustained reduction in disease burden.

    Eczematous external otitis is a chronic inflammatory disease and often difficult to treat. Our objective was to investigate the clinical effect and in vitro antibacterial potential of medical honey eardrops as treatment of eczematous external otitis. In a prospective study, 15 patients diagnosed with recurrent eczematous external otitis were treated with medical honey eardrops for 2 weeks. The following clinical outcomes were evaluated: visual analog scale of ear complaints, score of eczema, and eradication of bacterial infection. Furthermore, the antibacterial effect of honey eardrops against different bacterial strains was tested in vitro. Treatment resulted in less discomfort and itching and decreased signs of eczema, with high patient satisfaction and without adverse reactions. Honey eardrops showed a strong in vitro inhibitory activity against all tested strains but did not eradicate Staphylococcus aureus infection in vivo. The results of this preliminary study indicate a possible role of honey eardrops in eczematous ear disease.

    The management of hearing loss associated with otitis media is multifaceted. Clinical practice guidelines set the collaborative prescriptive standards for the medical management of otitis media in children. Treatment of this condition does not end with the medical practitioner. There are far-reaching effects of otitis media and its sequelae that permeate every aspect of patients' lives including physiological, educational, and psychosocial. Therefore, a comprehensive interprofessional treatment plan must be designed taking into consideration best practices from a range of professions to maximize clinical outcomes, including the treating physician, speech-language pathologist, clinical audiologist, educational audiologist, and professionals in the educational setting.

    This prospective study investigated the association of exposure to indoor secondary heating sources with otitis media and recurrent otitis media risk in infants. We enrolled mothers living in nonsmoking households and delivering babies between 1993 and 1996 in 12 Connecticut and Virginia hospitals. Biweekly telephone interviews during the first year of life assessed diagnoses from doctors' office visits and use of secondary home heating sources, air conditioner use, and day care. Otitis media episodes separated by more than 21 days were considered to be unique episodes. Recurrent otitis media was defined as 4 or more episodes of otitis media. Repeated-measures logistic regression modeling evaluated the association of kerosene heater, fireplace, or wood stove use with otitis media episodes while controlling for potential confounders. Logistic regression evaluated the relation of these secondary heating sources with recurrent otitis media. None of the secondary heating sources were associated with otitis media or with recurrent otitis media. Otitis media was associated with day care, the winter heating season, birth in the fall, white race, additional children in the home, and a maternal history of allergies in multivariate models. Recurrent otitis media was associated with day care, birth in the fall, white race, and a maternal history of allergies or asthma. We found no evidence that the intermittent use of secondary home heating sources increases the risk of otitis media or recurrent otitis media. This study confirms earlier findings regarding the importance of day care with respect to otitis media risk.

    Otitis media is a middle ear disease common in children under three years old. Otitis media can occur in normal individuals with no other symptoms or syndromes, but it is often seen in individuals clinically diagnosed with genetic diseases such as CHARGE syndrome, a complex genetic disease caused by mutation in the Chd7 gene and characterized by multiple birth defects. Although otitis media is common in human CHARGE syndrome patients, it has not been reported in mouse models of CHARGE syndrome. In this study, we report a mouse model with a spontaneous deletion mutation in the Chd7 gene and with chronic otitis media of early onset age accompanied by hearing loss. These mice also exhibit morphological alteration in the Eustachian tubes, dysregulation of epithelial proliferation, and decreased density of middle ear cilia. Gene expression profiling revealed up-regulation of Muc5ac, Muc5b and Tgf-β1 transcripts, the products of which are involved in mucin production and TGF pathway regulation. This is the first mouse model of CHARGE syndrome reported to show otitis media with effusion and it will be valuable for studying the etiology of otitis media and other symptoms in CHARGE syndrome.

The aim of this study is to determine the quality of life of Portuguese children with chronic otitis media with effusion and/or recurrent acute otitis media and the short-term impact of transtympanic ventilation tubes, using the Portuguese version of the OM-6 questionnaire, a valid, reliable and sensitive instrument to evaluate the health-related quality of life in children with otitis media. This study was conducted in a tertiary referral center, to where children are referred from primary care and hospital pediatric consultations. The Portuguese version of the OM-6 questionnaire was applied to children with chronic otitis media with effusion and/or recurrent acute otitis media. The instrument was re-administered at two months postoperatively to a group of children who underwent tympanostomy tube placement, to evaluate the change in quality of life with the surgical procedure. The study involved a sample of 169 children, aged between 6 months and 12 years (mean: 4.20 ± 2.05 years). The average score in the survey was 3.3 ± 1.47, of a maximum of 7 (worst quality of life). The domains 'caregiver concerns', 'hearing loss' and 'physical suffering' had the highest scores. The domain 'hearing loss' was correlated with the domain 'speech impairment' (rs = 0.41; p Portuguese children quality of life. Tympanostomy tubes improve quality of life related to the middle ear in most children. The application of validated disease-specific questionnaires allows an enhanced understanding of the impact of otitis media on Portuguese children quality of life and of the success of therapeutic measures.

    The case of a 5-year-old child diagnosed as having pervasive developmental disorder (PDD), autistic type, from age 1 is reported. After surgery of vegetation in middle ear for repetitive otitis, the child presented an improvement in autistic behaviours, previously expressed as impaired social interactions, qualitative abnormalities in communication, a marked delay in language development, echolalia, stereotypies and self-aggressive behaviours. The aim of this paper is to bring attention to occurrences of misdiagnosis of PDD, which can occur when an adequate screening of the autistic syndrome is not realised. The result of the surgery was an improvement in autistic behaviours, despite the persistence of less severe autistic traits that may be more closely related to Asperger’s syndrome. PMID:22736729

    Streptococcus pneumoniae strains lacking capsular polysaccharide have been increasingly reported in carriage and disease contexts. Since most cases of otitis media involve more than one bacterial species, we aimed to determine the capacity of a nonencapsulated S. pneumoniae clinical isolate to induce disease in the context of a single-species infection and as a polymicrobial infection with nontypeable Haemophilus influenzae. Using the chinchilla model of otitis media, we found that nonencapsulated S. pneumoniae colonizes the nasopharynx following intranasal inoculation, but does not readily ascend into the middle ear. However, when we inoculated nonencapsulated S. pneumoniae directly into the middle ear, the bacteria persisted for two weeks post-inoculation and induced symptoms consistent with chronic otitis media. During coinfection with nontypeable H. influenzae, both species persisted for one week and induced polymicrobial otitis media. We also observed that nontypeable H. influenzae conferred passive protection from killing by amoxicillin upon S. pneumoniae from within polymicrobial biofilms in vitro. Therefore, based on these results, we conclude that nonencapsulated pneumococci are a potential causative agent of chronic/recurrent otitis media, and can also cause mutualistic infection with other opportunists, which could complicate treatment outcomes. © FEMS 2014.

    The goal of this study was to obtain representative Kenyan data on the point prevalence of acute otitis media (AOM) and its sequelae (otitis media with effusion [OME] and chronic suppurative otitis media [CSOM]), a major cause of preventable hearing loss in children in developing countries. In Africa, there are limited studies on the prevalence of AOM and its sequelae in children. Study subjects were children aged 2 to 15 years and were enrolled from randomly selected preprimary and primary schools. After parental or guardian consent, subjects had a questionnaire administered, otoscopy and tympanometry were done, and audiometry was performed on those with ear problems detected on these examinations. A total of 9825 (75%) children was from rural schools. The prevalence of CSOM was 15 of 1000, OME was 15 of 1000, and AOM was 7 of 1000 children. Rural Rift Valley schoolchildren had the highest prevalence of CSOM (24 of 1000) compared with other regions (12 of 1000; P < .0001). Ear discharge occurred before 3.5 years in 50% of 901 children with ear discharge. A history of ear discharge was associated with abnormal tympanograms (odds ratio [OR], 11.9-19.2) and mild-to-severe hearing loss (OR, 21.6-38.6), even in children without ear disease (OR, 10.7-24.4). The burden of AOM sequelae in Kenyan preschool and schoolchildren is significant, and it occurs mostly in the first 4 years of life. By preventing early recurrent AOM, pneumococcal vaccination might partly avert nonreversible sequelae. © The Author 2015.

    A method of obtaining monospecific antiserum to the human secretory IgA is described. Immunochemically pure secretory IgA (isolated from human colostrum by fractionation with ammonium sulfate and gel-filtration on Sephadex G-200) was used for immunization of rabbits or sheep. Heterologous antibodies were removed by adsorption with commercial gamma globulin, normal serum, the serum of a patient suffering from A-myeloma with the IgA polymere and purified lactoferrin. Monospecific antiserum to the secretory IgA gave a reaction of complete immunological identity with the secretory IgA and a free secretory component.

    Tympanostomy tube placement is the most common ambulatory surgery performed on children in the United States. The goal of this study was to synthesize evidence for the effectiveness of tympanostomy tubes in children with chronic otitis media with effusion and recurrent acute otitis media. Searches were conducted in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Embase, and the Cumulative Index to Nursing and Allied Health Literature. Abstracts and full-text articles were independently screened by 2 investigators. A total of 147 articles were included. When feasible, random effects network meta-analyses were performed. Children with chronic otitis media with effusion treated with tympanostomy tubes compared with watchful waiting had a net decrease in mean hearing threshold of 9.1 dB (95% credible interval: -14.0 to -3.4) at 1 to 3 months and 0.0 (95% credible interval: -4.0 to 3.4) by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after placement of tympanostomy tubes. Associated adverse events are poorly defined and reported. Sparse evidence is available, applicable only to otherwise healthy children. Tympanostomy tubes improve hearing at 1 to 3 months compared with watchful waiting, with no evidence of benefit by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after tympanostomy tube placement, but the evidence base is severely limited. The benefits of tympanostomy tubes must be weighed against a variety of associated adverse events. Copyright © 2017 by the American Academy of Pediatrics.

    A radioimmunoassay was designed for the detection of secretory protein, a component of secretory immunoglobulin A, in human serum. The assay uses free secretory protein isolated from human colostrum, and antisera raised in rabbits to be purified antigen. The mean level of secretory protein in the control group was 2.34+-0.41 μg/ml (mean+-S.E.M.). The level in cord blood was slightly lower (0.74+-0.26 μg/ml), while the level in patients with ovarian carcinoma was significantly increased (12.67+-1.43 μg/ml). Pregnant women have increasingly secretory protein levels with increasing length of gestation (5.86+-2.02, 11.55+-1.30 and 17.00+-1.16 μg/ml for the first, second and third trimesters, respectively.

    Full Text Available Skull base osteomyelitis can involve the jugular foramen and its associated cranial nerves resulting in specific clinical syndromes. The Collet-Sicard syndrome describes the clinical manifestations of palsies involving cranial nerves IX, X, XI, and XII. We present a rare atypical case of skull base osteomyelitis originating from infection of the middle ear and causing the Collet-Sicard syndrome. Caused by Pseudomonas aeruginosa and Klebsiella pneumoniae, this occurred in an elderly diabetic man subsequent to retention of a cotton swab in an ear with chronic suppurative otitis media. This case report illustrates the possibility of retained cotton swabs contributing to the development of otitis media, skull base osteomyelitis, and ultimately the Collet-Sicard syndrome in the ears of immune-compromised patients with chronically perforated eardrums.

    Background Streptococcus pneumoniae (Spn) is one of the common bacteria responsible for episodic acute otitis media (AOM; non-otitis prone), recurrent AOM (otitis-prone) and AOM treatment failure (AOMTF) in children. Objective From a population of 268 children we sought to compare the serum IgG antibody titers to five different Spn proteins (PhtD, LytB, PcpA, PhtE and Ply) that are vaccine candidates in children with episodic AOM (n=34), who were otitis prone (n=35), and who had AOMTF (n=25) caused by Spn. Methods Antibody was quantitated by ELISA. Results At their acute AOM visit, anti-PhtD, -LytB, -PhtE and −Ply IgG antibody titers in otitis-prone children were significantly lower compared to non-otitis prone children (p otitis-prone, AOMTF and non-otitis prone children had no significant change in geometric mean IgG antibody titers against the five proteins (except for PhtE in children with AOMTF), but detailed analysis showed that about one-third of the children in each cohort had a 2-fold rise in antibody to the studied antigens. While non-otitis prone children had significant increases (p otitis-prone children either failed to show rises or the rises were significantly less than the non-otitis prone children. Conclusion Otitis-prone and AOMTF children mount less of an IgG serum antibody response than non-otitis prone children to Spn proteins following AOM and nasopharyngeal colonization. PMID:21487325

    Otitis media is inflammation of the middle ear and is usually caused by infection. It affects people of all ages but is particularly common in young children. Around 164 million people worldwide have long-term hearing loss caused by this condition, 90% of them in low-income countries. As zinc supplements prevent pneumonia in disadvantaged children, we wanted to investigate whether zinc supplements could also prevent otitis media. To evaluate whether zinc supplements prevent otitis media in adults and children of different ages. We searched CENTRAL (2014, Issue 1), MEDLINE (1950 to February week 4, 2014) and EMBASE (1974 to March 2014). Randomised, placebo-controlled trials of zinc supplements given at least once a week for at least a month for preventing otitis media. Two review authors independently assessed the eligibility and methodological quality of the included trials and extracted and analysed data. We summarised results using risk ratios (RRs) or rate ratios for dichotomous data and mean differences (MDs) for continuous data. We combined trial results where appropriate. No new trials were identified for inclusion in this update. We identified 12 trials for inclusion, 10 of which contributed outcomes data. There were a total of 6820 participants. In trials of healthy children living in low-income communities, two trials did not demonstrate a significant difference between the zinc-supplemented and placebo groups in the numbers of participants experiencing an episode of definite otitis media during follow-up (3191 participants); another trial showed a significantly lower incidence rate of otitis media in the zinc group (rate ratio 0.69, 95% confidence interval (CI) 0.61 to 0.79, n = 1621). A small trial of 39 infants undergoing treatment for severe malnutrition suggested a benefit of zinc for the mean number of episodes of otitis media (mean difference (MD) -1.12 episodes, 95% CI -2.21 to -0.03). Zinc supplements did not seem to cause any serious adverse

    Four cases of otitis externa secondary to radiotherapy are described. This fairly common complication of irradiation to the head and neck, may impede a satisfactory completion of the therapy. Water precautions and regular otoscopic examination of the ears should be encouraged as prevention or early recognition of the condition is essential for the well being of the patient. The treatment of established otitis externa consists of frequent aural toilet and the application of weak antiseptic solutions. However, complete resolution will not occur until the cutaneous reaction has fully settled. (author)

    Conventional 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. Children 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. Two 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). The results indicate that combined treatment of AOM with antibiotics and a leukotriene antagonist to control inflammation is useful for preventing progression to persistent SOM.

    To determine if the polymerase chain reaction (PCR) can detect bacterial DNA in pediatric middle ear effusions that are sterile by standard cultural methods. Single-center, blinded, comparative study of diagnostic assays. The PCR-based detection systems for Moraxella catarrhalis, Haemophilus influenzae, and Streptococcus pneumoniae were designed and validated using a battery of DNAs obtained from cultured bacteria. Chronic middle ear effusion specimens were collected and comparatively analyzed by culture and the PCR. Tertiary care pediatric hospital. A total of 97 middle ear effusions were collected from pediatric outpatients at Children's Hospital of Pittsburgh (Pa) during myringotomy and tube placement for chronic otitis media with effusion (duration > 3 months). All patients had failed multiple courses of antimicrobial therapy and were diagnosed by a combination of validated otoscopy and tympanograms. Differences in the percentage of positive test results between PCR-based assays and culture for M catarrhalis, H influenzae, and S pneumoniae. Of the 97 specimens of otitis media with effusion, 28 (28.9%) tested positive by both culture and PCR for M catarrhalis, H influenzae, or S pneumoniae. An additional 47 specimens (48%) were PCR positive/culture negative for these three bacterial species. Thus, 75 (77.3%) of the 97 specimens tested PCR positive for one or more of the three test organisms. The minimum number of bacterial genomic equivalents present in the average culture-negative ear was estimated to be greater than 10(4) based on dilutional experiments. The PCR-based assay systems can detect the presence of bacterial DNA in a significant percentage of culturally sterile middle ear effusions. While this finding is not proof of an active bacterial infectious process, the large number of bacterial genomic equivalents present in the ears is suggestive of an active process.

    1984-01-01

    Pseudomonas otitis externa in elderly diabetics may extend aggressively to adjacent bone, cranial nerves, meninges, and vessels, leading to a clinical diagnosis of ''malignant'' external otitis. Early diagnosis is necessary for successful treatment. This study compares the findings of initial radiographs, thin-section tomography of temporal bone, CT scans of head and neck, technetium-99m methylene diphosphonate (MDP) and gallium-67 citrate scintigraphy, and single-photon emission computed tomography (SPECT) for detection of temporal bone osteomylitis in ten patients fulfilling the clinical diagnostic criteria of malignant external otitis. Skull radiographs were negative in all of the eight patients studied. Thin-section tomography was positive in one of the seven patients studied using this modality. CT scanning suggested osteomyelitis in three of nine patients. Both Tc-99m and Ga-67 citrate scintigraphy were positive in 10 of 10 patients. These results suggest that technetium and gallium scintigraphy are more sensitive than radiographs and CT scans for early detection of malignant external otitis

    Full Text Available Introduction. Acute otitis is one of the most common pediatric infectious diseases that requires an accurate diagnosis in order to direct appropriate therapy to reduce the risk of complications. In this study pathogens collected from pediatric patients and their antibiotic susceptibility patterns were evaluated. Methods. Between May 2009 and May 2010, 739 samples (swabs taken from nasopharynx in case of acute otitis media and/or from ears in case of acute external otitis, collected from 680 patients, suffering of otalgia, admitted to the emergency department of our Hospital were studied.The specimens were submitted for routine bacterial cultures and the susceptibility tests were performed according to Clinical Laboratory Standards.

    Full Text Available La otitis media aguda es una de las infecciones respiratorias superiores más frecuentes en la infancia, fundamentalmente en niños menores de seis años. Su elevada incidencia y recidiva se deben a la interacción entre diferentes factores de riesgo. El signo más específico de presentación es la otalgia, acompañándose de fiebre, malestar y disminución de la audición.Por la frecuencia de niños con otitis media aguda en las consultas externas y de urgencia del hospital, nos planteamos conocer su comportamiento en el grupo estudiado. Se realizó un estudio descriptivo longitudinal retrospectivo a los pacientes que acudieron a consulta de Otorrinolaringología con otitis media aguda del Hospital Pediátrico Universitario Centro Habana, ubicado en La Habana, en el período comprendido entre enero de 2006 hasta diciembre de 2009. Se caracterizaron los pacientes en cuanto a edad, sexo, factores predisponentes, manifestaciones clínicas, etapa clínica de la otitis, recurrencia y tratamiento. Resultados: El sexo masculino y los menores de cinco años fueron los más afectados.

    Eosinophilic otitis media (EOM) is a refractory disease characterized by the accumulation of eosinophils in middle ear effusion and mucosa. We summarize current knowledge regarding the clinical characteristics and management of EOM. Although eosinophil activation in inflamed foci is involved in the pathogenesis of EOM, little is known about the fate of the eosinophils and aftermath of their cell death. We discuss the possibility that eosinophils undergo non-apoptotic cell death that worsens tissue damage and increases effusion viscosity. Unlike chronic otitis media, EOM is strongly associated with an allergic background. Corticosteroids are currently the only effective pharmacological treatment, and surgical intervention is often required. Mucosal eosinophils infiltrate extensively into the middle ear cavity where they are stimulated by locally produced activators including interleukin-5 and eotaxin. The eosinophils undergo cytolysis in the effusion, which represents a major fate of activated eosinophils in vivo. Recent data revealed cytolysis could be renamed as extracellular trap cell death (ETosis). ETosis represents suicidal cell death involving total cell degranulation and development of sticky chromatin structures (extracellular traps (ETs)). The characteristics of eosinophil- and neutrophil-derived ET polymers might contribute to the difference in viscosity of secretions between EOM and common chronic otitis media. The extracellular products remaining after eosinophil ETosis are an important aspect of EOM pathology. The concept of ETosis also has novel implications for potential therapeutic modalities in various eosinophilic disorders.

  13. Porosome: The Universal Secretory Portal in Cells

    2012-10-01

    In the past 50 years it was believed that during cell secretion, membrane-bound secretory vesicles completely merge at the cell plasma membrane resulting in the diffusion of intra-vesicular contents to the cell exterior and the compensatory retrieval of the excess membrane by endocytosis. This explanation made no sense or logic, since following cell secretion partially empty vesicles accumulate as demonstrated in electron micrographs. Furthermore, with the ``all or none'' mechanism of cell secretion by complete merger of secretory vesicle membrane at the cell plasma membrane, the cell is left with little regulation and control of the amount of content release. Moreover, it makes no sense for mammalian cells to possess such `all or none' mechanism of cell secretion, when even single-cell organisms have developed specialized and sophisticated secretory machinery, such as the secretion apparatus of Toxoplasma gondii, the contractile vacuoles in paramecium, or the various types of secretory structures in bacteria. Therefore, in 1993 in a News and Views article in Nature, E. Neher wrote ``It seems terribly wasteful that, during the release of hormones and neurotransmitters from a cell, the membrane of a vesicle should merge with the plasma membrane to be retrieved for recycling only seconds or minutes later.'' This conundrum in the molecular mechanism of cell secretion was finally resolved in 1997 following discovery of the ``Porosome,'' the universal secretory machinery in cells. Porosomes are supramolecular lipoprotein structures at the cell plasma membrane, where membrane-bound secretory vesicles transiently dock and fuse to release inravesicular contents to the outside during cell secretion. In the past decade, the composition of the porosome, its structure and dynamics at nm resolution and in real time, and its functional reconstitution into artificial lipid membrane, have all been elucidated. Since porosomes in exocrine and neuroendocrine cells measure 100-180 nm

    2018-01-01

    Necrotising otitis externa can be a devastating form of otitis externa. It typically tends to affect patients who are immunocompromised or diabetic. To date, there is very little in the literature about necrotising otitis externa in the immunocompetent patient population. The present paper discusses both the clinical and radiological findings in three cases of necrotising otitis externa in an immunocompetent patient cohort. The common factor among all three patients was their advanced age. Diagnosing necrotising otitis externa can be challenging because of the potentially non-specific symptoms and the absence of early radiological signs, particularly if patients are neither immunocompromised nor diabetic. Elderly patients should be considered in the same light as immunocompromised and diabetic patients in the context of necrotising otitis externa.

    Resident microbes promote many aspects of host development, although the mechanisms by which microbiota influence host tissues remain unclear. We showed previously that the microbiota is required for allocation of appropriate numbers of secretory cells in the zebrafish intestinal epithelium. Because Notch signaling is crucial for secretory fate determination, we conducted epistasis experiments to establish whether the microbiota modulates host Notch signaling. We also investigated whether innate immune signaling transduces microbiota cues via the Myd88 adaptor protein. We provide the first evidence that microbiota-induced, Myd88-dependent signaling inhibits host Notch signaling in the intestinal epithelium, thereby promoting secretory cell fate determination. These results connect microbiota activity via innate immune signaling to the Notch pathway, which also plays crucial roles in intestinal homeostasis throughout life and when impaired can result in chronic inflammation and cancer. © 2018.

  16. Automated Diagnosis of Otitis Media: Vocabulary and Grammar

    2013-01-01

    We propose a novel automated algorithm for classifying diagnostic categories of otitis media: acute otitis media, otitis media with effusion, and no effusion. Acute otitis media represents a bacterial superinfection of the middle ear fluid, while otitis media with effusion represents a sterile effusion that tends to subside spontaneously. Diagnosing children with acute otitis media is difficult, often leading to overprescription of antibiotics as they are beneficial only for children with acute otitis media. This underscores the need for an accurate and automated diagnostic algorithm. To that end, we design a feature set understood by both otoscopists and engineers based on the actual visual cues used by otoscopists; we term this the otitis media vocabulary. We also design a process to combine the vocabulary terms based on the decision process used by otoscopists; we term this the otitis media grammar. The algorithm achieves 89.9% classification accuracy, outperforming both clinicians who did not receive special training and state-of-the-art classifiers. PMID:23997759

    Full Text Available ABSTRACT INTRODUCTION: It is an erroneous but commonly held belief that intracranial complications (ICCs of chronic and acute otitis media (COM and AOM are past diseases or from developing countries. These problems remain, despite improvements in antibiotic care. OBJECTIVE: This paper analyzes the occurrence and clinical characteristics and course of the main ICCs of otitis media (OM. METHODS: Retrospective cohort study of 51 patients with ICCs from OM, drawn from all patients presenting with OM to the emergency room of a large inner-city tertiary care hospital over a 22-year period. RESULTS: 80% of cases were secondary to COM of which the incidence of ICC was 0.8%; 20% were due to AOM. The death occurrence was 7.8%, hearing loss in 90%, and permanent neurological sequelae in 29%. Patients were 61% male. In the majority, onset of ear disease had occurred during childhood. Delay of diagnosis of both the initial infection as well as the secondary ICC was significant. ICCs included brain abscess and meningitis in 78%, and lateral sinus thrombosis, empyema and otitic hydrocephalus in 13%, 8% and 1% of cases, respectively. Twenty-seven neurosurgical procedures and 43 otologic surgery procedures were performed. Two patients were too ill for surgical intervention. CONCLUSION: ICCs of OM, although uncommon, still occur. These cases require expensive, complex and long-term inpatient treatment and frequently result in hearing loss, neurological sequelae and mortality. It is important to be aware of this potentiality in children with COM, especially, and maintain a high index of suspicion in order to refer for otologic specialty care before such complications occur.

  19. Secretory immunity with special reference to the oral cavity

    2013-03-01

    Full Text Available The two principal antibody classes present in saliva are secretory IgA (SIgA and IgG; the former is produced as dimeric IgA by local plasma cells (PCs in the stroma of salivary glands and is transported through secretory epithelia by the polymeric Ig receptor (pIgR, also named membrane secretory component (SC. Most IgG in saliva is derived from the blood circulation by passive leakage mainly via gingival crevicular epithelium, although some may be locally produced in the gingiva or salivary glands. Gut-associated lymphoid tissue (GALT and nasopharynx-associated lymphoid tissue (NALT do not contribute equally to the pool of memory/effector B cells differentiating to mucosal PCs throughout the body. Thus, enteric immunostimulation may not be the best way to activate the production of salivary IgA antibodies although the level of specific SIgA in saliva may still reflect an intestinal immune response after enteric immunization. It remains unknown whether the IgA response in submandibular/sublingual glands is better related to B-cell induction in GALT than the parotid response. Such disparity is suggested by the levels of IgA in submandibular secretions of AIDS patients, paralleling their highly upregulated intestinal IgA system, while the parotid IgA level is decreased. Parotid SIgA could more consistently be linked to immune induction in palatine tonsils/adenoids (human NALT and cervical lymph nodes, as supported by the homing molecule profile observed after immune induction at these sites. Several other variables influence the levels of antibodies in salivary secretions. These include difficulties with reproducibility and standardization of immunoassays, the impact of flow rate, acute or chronic stress, protein loss during sample handling, and uncontrolled admixture of serum-derived IgG and monomeric IgA. Despite these problems, saliva is an easily accessible biological fluid with interesting scientific and clinical potentials.

    The adenoid pad has been considered a reservoir for bacteria in the pathogenesis of otitis media with effusion. This study aimed to characterize the middle ear microbiota in children with otitis media with effusion and establish whether a correlation exists between the middle ear and adenoid microbiota. Prospective, controlled study. Middle ear aspirates adenoid pad swabs were collected from 23 children undergoing ventilation tube insertion. Adenoid swabs from patients without ear disease were controls. Samples were analyzed using 16S rRNA sequencing on the Illumina MiSeq platform. Thirty-five middle ear samples were collected. The middle ear effusion microbiota was dominated by Alloiococcus otitidis (23% mean relative abundance), Haemophilus (22%), Moraxella (5%), and Streptococcus (5%). Alloiococcus shared an inverse correlation with Haemophilus (P = .049) and was found in greater relative abundance in unilateral effusion (P = .004). The microbiota of bilateral effusions from the same patient were similar (P effusion microbiota were found to be dissimilar to that of the adenoid (P = .01), whereas the adenoid microbiota of otitis media with effusion and control patients were similar (P > .05) (permutational multivariate analysis of the variance). Dissimilarities between the local microbiota of the adenoid and the middle ear question the theory that the adenoid pad is a significant reservoir to the middle ear in children with otitis media with effusion. A otitidis had the greatest cumulative relative abundance, particularly in unilateral effusions, and shares an inverse correlation with the relative abundance of Haemophilus.

    Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM. The clinical features of EOM closely resemble localized eosinophilic granulomatosis polyangiitis, therefore it is necessary to be vigilant to the symptoms of mononeuritis, polyneuritis, and skin purpura during diagnosis. Standard treatment for EOM is the instillation of triamcinolone acetonide into the mesotympanum. However, severe cases exhibiting strong inflammation and otorrhea are not easily controlled with antibiotics and/or corticosteroids. We proposed the introduction of a severity score to evaluate the severity of EOM. This score correlated with local IgE levels in middle ear effusion. Clinically, the risk factors associated with this severity score were body mass index, and the duration of bronchial asthma (from the onset of BA to the age of the first consultation of otitis media to our hospital). We emphasize that early diagnosis and adequate treatment are vital in preventing progressive and sudden hearing loss resulting from EOM.

    The complications of otitis media (intra-cranial and extra-cranial) used to have a high morbidity and mortality in the pre-antibiotic era, but these are now relatively rare, mainly due to the use of antibiotics and the use of ventilation tubes, reducing the incidence of such complications significantly. Currently, an early suspicion of these complications is a major challenge for diagnosis and management. The cases of 5 patients (all male) are presented, who were diagnosed with complicated otitis media, 80% (4) with a mean age of 34.6 years (17-52). There was major comorbidity in 60% (3), with one patient with diabetes mellitus type 2, and two with chronic renal failure. There were 3 (60%) intra-cranial complications: one patient with thrombosis of the sigmoid sinus and a cerebellar abscess; another with a retroauricular and brain abscess, and a third with meningitis. Of the 2 (40%) extra-cranial complications: one patient had a Bezold abscess, and the other with a soft tissue abscess and petrositis. All patients were managed with surgery and antibiotic therapy, with 100% survival (5), and with no neurological sequelae. The clinical course of otitis media is usually short, limiting the infection process in the majority of patients due to the immune response and sensitivity of the microbe to the antibiotic used. However, a small number of patients (1-5%) may develop complications. Otitis media is a common disease in our country, complications are rare, but should be suspected when the picture is of torpid evolution with clinical worsening and manifestation of neurological signs.

  5. Synaptic Control of Secretory Trafficking in Dendrites

    Directory of Open Access Journals (Sweden)

    Cyril Hanus

    2014-06-01

    Full Text Available Localized signaling in neuronal dendrites requires tight spatial control of membrane composition. Upon initial synthesis, nascent secretory cargo in dendrites exits the endoplasmic reticulum (ER from local zones of ER complexity that are spatially coupled to post-ER compartments. Although newly synthesized membrane proteins can be processed locally, the mechanisms that control the spatial range of secretory cargo transport in dendritic segments are unknown. Here, we monitored the dynamics of nascent membrane proteins in dendritic post-ER compartments under regimes of low or increased neuronal activity. In response to activity blockade, post-ER carriers are highly mobile and are transported over long distances. Conversely, increasing synaptic activity dramatically restricts the spatial scale of post-ER trafficking along dendrites. This activity-induced confinement of secretory cargo requires site-specific phosphorylation of the kinesin motor KIF17 by Ca2+/calmodulin-dependent protein kinases (CaMK. Thus, the length scales of early secretory trafficking in dendrites are tuned by activity-dependent regulation of microtubule-dependent transport.

    Dihydroxy bile acids, such as chenodeoxycholic acid (CDCA), are well known to promote colonic fluid and electrolyte secretion, thereby causing diarrhoea associated with bile acid malabsorption. However, CDCA is rapidly metabolised by colonic bacteria to ursodeoxycholic acid (UDCA), the effects of which on epithelial transport are poorly characterised. Here, we investigated the role of UDCA in the regulation of colonic epithelial secretion. Cl− secretion was measured across voltage-clamped monolayers of T84 cells and muscle-stripped sections of mouse or human colon. Cell surface biotinylation was used to assess abundance/surface expression of transport proteins. Acute (15 min) treatment of T84 cells with bilateral UDCA attenuated Cl− secretory responses to the Ca2+ and cAMP-dependent secretagogues carbachol (CCh) and forskolin (FSK) to 14.0 ± 3.8 and 40.2 ± 7.4% of controls, respectively (n= 18, P acid (LCA). Accordingly, LCA (50–200 μm) enhanced agonist-induced secretory responses in vitro and a metabolically stable UDCA analogue, 6α-methyl-UDCA, exerted anti-secretory actions in vitro and in vivo. In conclusion, UDCA exerts direct anti-secretory actions on colonic epithelial cells and metabolically stable derivatives of the bile acid may offer a new approach for treating intestinal diseases associated with diarrhoea.

    Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

    1987-02-19

    In a randomized, double-blind, placebo-controlled trial involving 518 infants and children who had otitis media with effusion ("secretory" otitis media), we evaluated the efficacy of a two-week course of amoxicillin (40 mg per kilogram of body weight per day) with and without a four-week course of an oral decongestant-antihistamine combination. Among the 474 subjects who were evaluated at the four-week end point, the rate of resolution of middle-ear effusion was twice as high in those treated with amoxicillin, either with or without the decongestant-antihistamine, as in those who received placebo (P less than 0.001), but 69.8 percent of the amoxicillin-treated subjects still had effusion. Among both the amoxicillin-treated subjects and the placebo-treated subjects, resolution was more likely in those with initially unilateral effusion, in those who had had effusion for eight weeks or less, and in those without an upper respiratory tract infection at the four-week end point. Side effects were reported more often in subjects who received decongestant-antihistamine than in those who did not. Among the subjects without effusion at the four-week end point, recurrent effusion developed in approximately half those in both the amoxicillin and placebo groups during the subsequent three months. We conclude that in infants and children with otitis media with effusion, amoxicillin treatment increases to some extent the likelihood of resolution.

    Objective The objective is to perform a comprehensive review of the literature up to 2015 on the genetics and precision medicine relevant to otitis media. Data Sources PubMed database of the National Library of Medicine. Review Methods Two subpanels were formed comprising experts in the genetics and precision medicine of otitis media. Each of the panels reviewed the literature in their respective fields and wrote draft reviews. The reviews were shared with all panel members, and a merged draft was created. The entire panel met at the 18th International Symposium on Recent Advances in Otitis Media in June 2015 and discussed the review and refined the content. A final draft was made, circulated, and approved by the panel members. Conclusion Many genes relevant to otitis media have been identified in the last 4 years in advancing our knowledge regarding the predisposition of the middle ear mucosa to commensals and pathogens. Advances include mutant animal models and clinical studies. Many signaling pathways are involved in the predisposition of otitis media. Implications for Practice New knowledge on the genetic background relevant to otitis media forms a basis of novel potential interventions, including potential new ways to treat otitis media.

Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position, type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. Results: 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to otitis media with effusion. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding.

    Highlights: • Membrane protein Orai1 can be used to report the fusion properties of RFPs. • Artificial puncta are affected by dissociation constant as well as pKa of RFPs. • Among tested RFPs mOrange2 is the best choice for secretory protein labeling. - Abstract: Red fluorescent proteins (RFPs) are useful tools for live cell and multi-color imaging in biological studies. However, when labeling proteins in secretory pathway, many RFPs are prone to form artificial puncta, which may severely impede their further uses. Here we report a fast and easy method to evaluate RFPs fusion properties by attaching RFPs to an environment sensitive membrane protein Orai1. In addition, we revealed that intracellular artificial puncta are actually colocalized with lysosome, thus besides monomeric properties, pKa value of RFPs is also a key factor for forming intracellular artificial puncta. In summary, our current study provides a useful guide for choosing appropriate RFP for labeling secretory membrane proteins. Among RFPs tested, mOrange2 is highly recommended based on excellent monomeric property, appropriate pKa and high brightness.

    To assess the degree of reliability of computed tomography (CT) and the agreement between the imaging studies and intraoperative findings in chronic otitis media (COM) with cholesteatoma. We studied 51 patients diagnosed clinically as having inflammatory disease of the middle ear. All the patients under-went high-resolution Ct of temporal bone in axial and coronal planes. The imaging studies were retrospectively correlated with the intraoperative findings and the sensitivity of CT in the detection of erosive cholesteatoma was determined. Open radical mastoidectomy is the surgical technique most frequently used to treat cholesteatoma in our center. The greatest radio-surgical correlation was achieved in the detection of masses presenting soft tissue attenuation in air-filled cavities in middle ear (100%) and in bone erosion (87.5%). The 20 patients (39%) who were diagnosed as having COM with cholesteatoma underwent surgical treatment in our center. CT is the technique of choice in the study of COM with cholesteatoma, providing basic and necessary information for the image-based diagnosis of this disease, the detection of masses presenting soft tissue attenuation and bone erosion. We also point out the role of CT as an intraoperative guide and discuss its low sensitivity for the detection of small areas of dura mater exposure, ossicular luxation and facial canal dehiscence.

    In recent years, the multislice CT system has come into practical use that enables table movement of half mm, resulting in a significant improvement in resolution. The use of this CT system enables to depict the entire auditory ossicles, including the stapes. 3D reconstruction was performed using helical CT data in 5 patients with chronic otitis media and 5 patients with cholesteatoma. An Aquilion Multi (Toshiba) multislice helical CT scanner and a Xtension (Toshiba) image workstation were used in this study. We demonstrated the 3D display with axial, coronal and sagittal images. Compared with the normal ears, it was necessary to set a higher threshold for the affected ears. It is important to select suitable threshold for demonstration of 3D images optimally. Bone destruction of the stapes was confirmed at surgery in 2 ears. The stapes was observed at 3D-CT imaging in other 18 ears. It was found that the 3D images of the ossicular destruction in ears with cholesteatoma were consistent with surgical findings. It is therefore concluded that 3D imaging of the middle ear using a multislice CT scanner is clinically useful. (author)

    Otitis media (OM) is amongst the most common childhood diseases and is associated with multiple microbial pathogens within the middle ear. Global and temporal monitoring of predominant bacterial pathogens is important to inform new treatment strategies, vaccine development and to monitor the impact of vaccine implementation to improve progress toward global OM prevention. A systematic review of published reports of microbiology of acute otitis media (AOM) and otitis media with effusion (OME) from January, 1970 to August 2014, was performed using PubMed databases. This review confirmed that Streptococcus pneumoniae and Haemophilus influenzae, remain the predominant bacterial pathogens, with S. pneumoniae the predominant bacterium in the majority reports from AOM patients. In contrast, H. influenzae was the predominant bacterium for patients experiencing chronic OME, recurrent AOM and AOM with treatment failure. This result was consistent, even where improved detection sensitivity from the use of polymerase chain reaction (PCR) rather than bacterial culture was conducted. On average, PCR analyses increased the frequency of detection of S. pneumoniae and H. influenzae 3.2 fold compared to culture, whilst Moraxella catarrhalis was 4.5 times more frequently identified by PCR. Molecular methods can also improve monitoring of regional changes in the serotypes and identification frequency of S. pneumoniae and H. influenzae over time or after vaccine implementation, such as after introduction of the 7-valent pneumococcal conjugate vaccine. Globally, S. pneumoniae and H. influenzae remain the predominant otopathogens associated with OM as identified through bacterial culture; however, molecular methods continue to improve the frequency and accuracy of detection of individual serotypes. Ongoing monitoring with appropriate detection methods for OM pathogens can support development of improved vaccines to provide protection from the complex combination of otopathogens within

    OBJECTIVES: To establish a clinicopathological profile of malignant otitis externa (MOE) in an Australian tertiary referral institution. STUDY DESIGN: Retrospective cohort outcomes study. METHODS: 24 patients were identified with MOE between January 1998 and July 2007. Patients were classified into Radiological Grades I-IV. Laboratory investigations Including C-reactive protein (CRP), white cell count (WCC), glycosylated haemoglobin (HBA1c) and average glucose level over admission were recorded. RESULTS: Radiological Grade was significantly associated with duration of therapy (rank correlation 0.57, p = 0.004). CRP was a useful indicator confirming disease resolution. Diabetics with MOE had elevated average blood sugar levels during their Hospital admission (p < 0.001) and had poor overall glycaemic control represented by Elevated HBA1c scores (p < 0.001). CONCLUSIONS: Malignant otitis externa is a rare disease, which is best managed in a multidisciplinary team setting. This practical grading system can be used to predict the duration of therapy at time of diagnosis, which enables the efficient utilisation of Hospital resources. Poorly controlled diabetics are more susceptible to developing. MOE than diabetics with satisfactory glycaemic control and may represent a subgroup of more brittle diabetics. CRP combined with appropriate clinical and radiological investigations is useful in assessing disease resolution.

    Determine the incidence of otological and endocranial complications of acute otitis media, taking into account previous treatments and the development of complications. Retrospective follow-up study between March 1996-2003 including 16 patients: 9 men, 7 women. Nine patients (56.25%) had intracranial complications and seven otological ones. In the first group, 6 developed meningitis by Streptococcus pneumoniae, one sigmoid sinus thromboflebitis, one multiple abscesses, and one subdural empiema and encephalitis. Otological complications were six acute mastoiditis and the other one a facial paralysis. The child with thromboflebitis underwent mastoidectomy and closed meningeal comunication; 5 of the acute mastoiditis were operated on and the other received traditional treatment. The meningitis received medication. Two died, one because of a subdural empiema and the other due to meningitis. Despite the advances made by antibiotherapy and diagnosis, the complications of otitis media are still frequent. The pediatrician and otorhinolaryngologist should be on the alert for these as well as for Pneumococcus and its high resistance.

    Stringently defined otitis-prone (sOP) children represent a new classification of the otitis-prone condition. Previous studies showed dysfunction in Ab, B-cell memory and T-cell memory responses. We sought to determine whether there are defects in numbers, phenotype and/or function of professional APC in the peripheral blood of sOP infants. APC phenotypic counts, MHC II expression and intracellular cytokine levels were determined in response to TLR7/8 (R848) stimulation by flow cytometry. Innate immune mRNA expression was measured using RT-PCR and cytokines were measured using Luminex technology. Significant (P otitis-prone (NOP) age-matched infants. No significant differences in APC activation or function were observed. Expression of various TLRs, intracellular signaling molecules and downstream cytokines was also not found to be significantly different between sOP and NOP infants. Higher numbers of APCs in sOP infants suggest the possibility of a persistent mucosal inflammatory status. Transcriptional and cytokine profiles of PBMCs among sOP infants suggest their systemic innate responses are not different compared to NOP infants. © The Author(s) 2015.

    Defined by lasting more than four weeks - is a common but often challenging clinical scenario. It is important to be aware that diarrhoea means different things to different patients. The evaluation of chronic diarrhoea depends on taking an excellent history and careful physical examination as well as planning investigations thoughtfully. Functional diarrhea ist the most common cause of chronic diarrhea in the developed countries and motility disorders are more common than inflammatory, osmotic or secretory causes. In some cases categorizing patients by their stool characteristics can be helpful in directing further evaluation.

    Full Text Available The events involved in the maturation process of acinar secretory granules of rat parotid gland were investigated ultrastructurally and cytochemically by using a battery of four lectins [Triticum vulgaris agglutinin (WGA, Ulex europaeus agglutinin I (UEA-I, Glycine max agglutinin (SBA, Arachys hypogaea agglutinin (PNA]. In order to facilitate the study, parotid glands were chronically stimulated with isoproterenol to induce secretion. Specimens were embedded in the Lowicryl K4M resin. The trans-Golgi network (TGN derived secretory granules, which we refer to as immature secretory granules, were found to be intermediate structures in the biogenesis process of the secretory granules in the rat parotid acinar cell. These early structures do not seem to be the immediate precursor of the mature secretory granules: in fact, a subsequent interaction process between these early immature granule forms and TGN elements seems to occur, leading, finally, to the mature granules. These findings could explain the origin of the polymorphic subpopulations of the secretory granules in the normal acinar cells of the rat parotid gland. The lectin staining patterns were characteristic of each lectin. Immature and mature secretory gran- ules were labelled with WGA, SBA, PNA, and lightly with UEA-I. Cis and intermediate cisternae of the Golgi apparatus were labelled with WGA, and trans cisternae with WGA and SBA.

    Fifty per cent of children with serous otitis media may have some balance disturbances. To evaluate vestibular function in children with otitis media with effusion. The control group comprised 25 children with bilateral normal hearing and middle-ear function. The study group consisted of 30 children with bilateral otitis media with effusion; these were divided into 2 subgroups according to air-bone gap size. Measures included the Arabic Dizziness Handicap Inventory, an imbalance evaluation sheet for children, vestibular bedside tests for children, and air- and bone-conducted vestibular-evoked myogenic potential testing. Arabic Dizziness Handicap Inventory scores and some vestibular bedside test results were significantly abnormal, with normal video-nystagmography results, in children with otitis media with effusion. Air-conducted vestibular-evoked myogenic potentials were recorded in 73 per cent of children with otitis media with effusion, with significantly delayed latencies. Bone-conducted vestibular-evoked myogenic potentials were successfully detected in 100 per cent of children with otitis media with effusion with similar results to the control group. The Arabic Dizziness Handicap Inventory and vestibular bedside tests are valuable tools for detecting vestibular impairment in children. Bone-conducted vestibular-evoked myogenic potentials are useful for vestibular system evaluation.

    The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

    The shiitake mushroom, Lentinula edodes, has an extracelluar secretory-type laccase, Lcc1, and a fruiting-body-accumulation-type laccase, Lcc4. We previously reported the production of Lcc1 by plant cells, but had difficulty producing Lcc4. Here, we report the production of Lcc1 and Lcc4 by Aspergillus oryzae and the extracellular secretory production of Lcc4 using a modified secretion signal peptide (SP) from Lcc1. Sp-Lcc4 produced by A. oryzae had biochemical activities similar to Lcc4 produced by L. edodes. Lcc1 did not react with beta-(3,4-dihydroxyphenol) alanine (DOPA), but Lcc4 from L. edodes and A. oryzae could oxidize DOPA. K(M) values for the substrates 2,2'-azino-di-(3-ethylbenzthiazolinsulfonate), 2,6-dimethoxyphenol, guaiacol, pyrogallol, and catechol were similar for Lcc4 and Sp-Lcc4. In conclusion, a non-secretory-type fungal laccase is secreted into the culture media with its original enzymatic properties by exploiting modified secretory signal peptide. 2008 Elsevier GmbH.

    Full Text Available Diabetes type 2 is a chronic metabolic disorder. Pathogenesis of diabetes type 2 results from the impaired insulin secretion, impaired insulin action and increased endogenous glucose production. Diabetes evolves through several phases characterized by qualitative and quantitative changes of beta cell secretory function. The aim of our study was to analyze the impact of diabetes duration on beta cell secretory function and insulin resistance. The results indicated significant negative correlation of diabetes duration and fasting insulinemia, as well as beta cell secretory function assessed by HOMA β index. Our study also found significant negative correlation of diabetes duration and insulin resistance assessed by HOMA IR index. Significant positive correlation was established between beta cell secretory capacity (fasting insulinemia and HOMA β and insulin resistance assessed by HOMA IR index, independently of diabetes duration. These results indicate that: beta cell secretory capacity, assessed by HOMA β index, significantly decreases with diabetes duration. In parallel with decrease of fasting insulinemia, reduction of insulin resistance assessed by HOMA IR index was found as well.

    Full Text Available Introduction: In 1904, Giuseppe Gradenigo published his case series on the triad of ipsilateral abducens nerve palsy, facial pain in the trigeminal nerve distribution, and suppurative otitis media, which would subsequently be referred to as Gradenigo syndrome. Case Report: Our patient was a 36-year-old female, 23 weeks pregnant, with a 6-day history of right-sided otalgia and hearing loss and a 4-day history of purulent otorrhea, who presented with severe, holocephalic headache, meningeal signs, fever, photophobia, and mental status decline. Lumbar puncture yielded a white blood cell count of 1,559 cells/mm3 with 95% polymorphonuclear leukocytes, a red blood cell count of 111 cells/mm3, a protein level of 61 mg/dl, and a glucose level of Streptococcus pneumoniae and treated with ceftriaxone. On the second hospital day, she developed horizontal diplopia due to right abducens nerve palsy and right mydriasis. Both symptoms resolved on the third hospital day. Erosion of temporal bone and opacification of mastoid air cells was shown on CT scan. A CT venogram showed an irregularity of the left transverse and superior sagittal sinuses. She was treated with enoxaparin for possible sinus thrombosis. Discussion: This case demonstrates rare but serious sequelae of otitis media and Gradenigo syndrome. Holocephalic headache from meningitis masked trigeminal pain. Involvement of the ipsilateral petrous apex and surrounding structures on imaging and clinical improvement with antibiotic treatment supports Gradenigo syndrome over intracranial hypertension due to venous sinus thrombosis as the cause of the abducens nerve palsy.

    Full Text Available Background The aim of this study was to assess the prevalence of hospitalisation for otitis media across the different risk indicators for Western Australian children (less than 15 years old over a 10-year period. Method This retrospective population-based study used the deidentified detailed data of children under the age of 15 years, hospitalised for otitis media (OM, as determined by principal diagnosis (ICD-10AM and obtained from the Western Australian (WA Hospital Morbidity Dataset for 10 financial years from 1999–2000 to 2008–2009. Various risk indicators, including age, gender, Indigenous status, insurance status, hospital area, hospital type, and length of stay were also analysed. Results Out of 26,294 cases of in-hospital care, Indigenous children comprised 4.7 per cent (n=1,226, while the non-Indigenous children comprised 95.3 per cent (n=25,068. The majority of the children, nearly 98.8 per cent, were admitted for chronic OM. The children were grouped into three age groups, namely, 0–4 years, 5–9 years, and 10–14 years. Nearly two-thirds of all cases were in the 0–4-year age group. Significantly more non-Indigenous (51 per cent than Indigenous children (2 per cent had private health insurance. The hospitalisation rates were directly proportional between the number of Indigenous children living in the area and the increasing remoteness of the area along with greater socioeconomic disadvantage. There were 24 per cent more cases from very remote areas compared to highly accessible areas, and there were 60 per cent more cases from the most disadvantaged socioeconomic category, compared with the least disadvantaged category, for Indigenous children. Conclusion These data depict the variations in prevalence of otitis media hospitalisations within the community, as affected by various risk indicators.

    The objective of this investigation was to identify proteins in the pulmonary extracellular lining (EL) that are secreted by cells of the pulmonary epithelium. Pulmonary lavage effluents from the lungs of rabbits were centrifuged to remove all cells and particulate materials. Serum proteins were removed by repeatedly passing concentrated lavage effluent fluid through an affinity column containing IgG fraction of goat anti-rabbit (whole serum) antiserum bound to Sepharose-4B. Nonserum proteins accounted for 21.3 +/- 10.3% of the total soluble proteins in pulmonary lavage effluents. Serum free lavage effluents (SFL) contained 25 identifiable proteins as determined by using SDS-PAGE under reducing conditions. Of these proteins approximately 73% was accounted for by a single protein with MW of 66 kd. The secretory nature of the proteins present in SFL was investigated by studying the incorporation of 35 S-methionine into proteins released by lung slices and trachea followed by SDS-PAGE and autoradiography. Many, but not all proteins present in SFL were identified as proteins secreted by pulmonary tissues. The major secretory proteins appeared to have MWs of 59, 53, 48, 43, 24, 14, and 6 kd under reducing conditions. These data demonstrate the presence of several proteins in the pulmonary extracellular lining that appear to be secreted by the pulmonary epithelium

    The aim of this paper was to define the secretory pattern of growth hormone (GH) under basal conditions in fasted, conscious, male dogs accustomed to handling. Blood samples were withdrawn from a cephalic vein at 15-min intervals. In this way, any ultradian rhythms, if present, could be detected within the frequency range of 0.042-2 cycles/h. In addition, samples were drawn at either 1- or 2.5-min intervals for 2.5 or 5 h to determine whether frequency components greater than 2 cycles/h were present. GH was measured by radioimmunoassay and the raw data were submitted to time series analysis employing power spectral estimation by means of fast Fourier transformation techniques. Peak plasma levels were up to 12 times higher than the baseline concentration of ∼ 1 ng/ml. Spectral analysis revealed an endogenous frequency of 0.22 cycles/h, i.e., a periodicity of 4.5 h/cycle. The results indicate that under basal conditions the secretory bursts of canine GH are limited to one peak every 4.5 h

    Although the inner ear has long been reported to be susceptible to middle ear disease, little is known of the inflammatory mechanisms that might cause permanent sensorineural hearing loss. Recent studies have shown inner ear tissues are capable of expressing inflammatory cytokines during otitis media. However, little quantitative information is available concerning cytokine gene expression in the inner ear and the protein products that result. Therefore, this study was conducted of mouse middle and inner ear during acute otitis media to measure the relationship between inflammatory cytokine genes and their protein products with quantitative RT-PCR and ELISA, respectively. Balb/c mice were inoculated transtympanically with heat-killed Haemophilus influenzae and middle and inner ear tissues collected for either quantitative RT-PCR microarrays or ELISA multiplex arrays. mRNA for several cytokine genes was significantly increased in both the middle and inner ear at 6 h. In the inner ear, these included MIP-2 (448 fold), IL-6 (126 fold), IL-1β (7.8 fold), IL-10 (10.7 fold), TNFα (1.8 fold), and IL-1α (1.5 fold). The 24 h samples showed a similar pattern of gene expression, although generally at lower levels. In parallel, the ELISA showed the related cytokines were present in the inner ear at concentrations higher by 2-122 fold higher at 18 h, declining slightly from there at 24 h. Immunohistochemistry with antibodies to a number of these cytokines demonstrated they occurred in greater amounts in the inner ear tissues. These findings demonstrate considerable inflammatory gene expression and gene products in the inner ear following acute otitis media. These higher cytokine levels suggest one potential mechanism for the permanent hearing loss seen in some cases of acute and chronic otitis media. Copyright © 2015 Elsevier B.V. All rights reserved.

    Ten guinea pigs were irradiated with 30 Gy of x-radiation. Five were killed on the eighth day after irradiation, and the remainder were killed at the sixteenth day after irradiation. At the time of death, examination was made of the ciliary activity and the fine structure of the middle ear mucosa. Serous effusion was found in each tympanic cavity of all animals. It was shown also that the guinea pig, when irradiated with 30 Gy of x-radiation, exhibits pathologic abnormalities similar to those in humans with otitis media with effusion: degeneration of cilia or ciliated cells and changes in the vascular system (capillary injury and increased capillary permeability). Functional examinations showed that x-ray irradiation has delayed effects on ciliary activity, and the effects are much greater at the sixteenth day than at the eighth day. We speculate that the accumulation of effusion can be, at least partially, a consequence of ciliary dysfunction. The induction of sterile effusion by the use of x-ray irradiation provides a unique animal model for chronic otitis media with effusion of the serous type

    The authors report about the efficacy of inserted tympanostomy tube in children with serous otitis media. The aim of the authors was to assess the status of eardrum, the function of Eustachian tube and hearing level 10 years after the use of tympanostomy tube. Patients filled out a questionnaire and microscopic examination of tympanic membrane, tympanometry, Eustachian tube function examination, and audiometry tests were performed. In the period of 2003-2004, ventilation tube insertion was performed in 711 patients in the ENT Department of Pediatric Health Center of University of Szeged. In 349 patients adenotomy and tympanostomy tube insertion, in 18 cases tonsillectomy and grommet insertion and in 344 patients only typmanostomy tube insertion were performed. Due to objective difficulties (address change, no phone number) 453 patients were asked for control test and 312 persons accepted the invitation. Normal hearing level was found in 84.6% of patients and normal tympanometry result occurred in 82%. Tympanic ventilation disorder, perforation of tympanic membrane, sensorineural hearing loss and sensorineural hearing loss due to noise exposure were diagnosed. Application of tympanostomy tube is effective in the treatment of serous otitis media resulting from ventilation disorder. The authors draw attention to the importance of tympanometry examination to prevent the adhesive processes and cholesteatoma in chronic ventilation disorder of the middle ear.

    Acute otitis media (AOM) and otitis media with effusion (OME) are common infections in children, and their diagnosis and treatment have significant impacts on the health of children and the costs of providing national medical care. In 2009, the Korean Otologic Society organized a committee composed of experts in the field of otolaryngology, pediatrics, and family medicine to develop Korean clinical practice guidelines (CPG) for otitis media in children with the goal of meeting regional medical and social needs in Korea. For this purpose, the committee adapted existing guidelines. A comprehensive literature review was carried out primarily from 2004 to 2009 using medical search engines including data from Korea. A draft was written after a national questionnaire survey and several public audits, and it was editorially supervised by senior advisors before publication of the final report. These evidence-based guidelines for the management of otitis media in children provide recommendations to primary practitioners for the diagnosis and treatment of children younger than 15 yr old with uncomplicated AOM and OME. The guidelines include recommendations regarding diagnosis, treatment options, prevention and parent education, medical records, referral, and complementary/alternative medicine for treating pediatric otitis media.

    A duplication variant within middle-ear-specific gene A2ML1 co-segregates with otitis media in an indigenous Filipino pedigree (LOD score=7.5 at reduced penetrance) and lies within a founder haplotype that is also shared by three otitis-prone European- and Hispanic-American children, but is absent in non-otitis-prone children and >62,000 next-generation sequences. Seven additional A2ML1 variants were identified in six otitis-prone children. Collectively our studies support a role for A2ML1 in the pathophysiology of otitis media. PMID:26121085

    Qualitative technetium Tc 99m bone scintigraphy using phosphate compounds and gallium 67 scintigraphy were described as a helpful means in diagnosing necrotizing external otitis (NEO). They were, however, claimed to be nonspecific. Quantitative Tc 99m methylene diphosphonate bone scintigraphy and gallium 67 scintigraphy were performed in eight patients with NEO and in 20 patients with severe external otitis, in order to prove usefulness of scintigraphy in the diagnosis of NEO. Ratios of lesion to nonlesion for bone scintigraphy were 1.67 ± 0.16 in patients with NEO and 1.08 ± 0.09 in patients with severe external otitis, and for gallium 67 scintigraphy they were 1.35 ± 0.24 in NEO patients and 1.05 ± 0.03 in patients with severe external otitis. There was no difference in uptake between diabetic patients with severe external otitis and nondiabetic patients. The scintigraphic studies were also evaluated using a qualitative scoring method (scores 0 to +4), according to the intensity of the radiopharmaceutical uptake. This method was found to be inferior in the diagnosis of NEO compared with the quantitative method. We conclude that lesion-to-nonlesion ratios greater than 1.5 and 1.3 on bone and gallium 67 scintigraphy, respectively, are indicative of NEO. Quantitative bone scintigraphy, which is quicker to perform, may be used as a single imaging modality for the diagnosis of NEO

    Secretary Otitis media with effusion (OME) is the accumulation of mucus in the middle ear and sometimes in the mastoid air cell system. The main etiological factor is alteration in mucociliary system of middle ear secondary to ET malfunction which may be primary or secondary. OME is the cause of concern due to its occurance in paediatric age group, highest at 2 years of age, presenting as impairment of hearing leading to delayed speech and language development, poor academic performance and behavioral problems. In spite of this there are no confirmed guidelines of treatment to overcome. Many treatment options are available medical as well as surgical. Prospective study conducted to evaluate various treatment options revealed that auto inflation of ET is the main stay of treatment. If the ET malfunction is due to any reasons like adenoids, deviated nasal septum, hypertrophied turbinates or any other cause surgical intervention of the same gives 100% results. Medical management gives good results but recurrence is equally common.

    The objective of the present work was to study the influence of allelic variant associations of 1-beta interleukin (C3953T, &511C, T31C), interleukin-6 (C174G), and tumour necrosis factor-alpha (G308A) gene polymorphisms on the serum cytokine level in the patients presenting with chronic suppurative otitis media. A total of 299 patients at the age varying from 16 to 55 years with this condition divided into three groups were examined. Group 1 was comprised of 146 patients suffering from the tubotympanic form of chronic suppurative otitis media (CSOM). Group 2 was composed of 153 patients with epitympanic antral form of this condition. The control group included 183 subjects who have never suffered pathological changes in the middle ear. Human genomic DNA was analyzed with the use of the polymerase chain reaction (PCR). The serum cytokine levels were measured by the solid-state enzyme immunoassay in the beginning and at the end of the treatment period. The study has demonstrated that 56.2% of the healthy residents of the trans-Baikal region had the C/T Il-1b (C3953T) genotype. 79.1% of the patients presenting with the carious carious-destructive form of chronic suppurative otitis media were the heterozygous carriers of the T511C gene of 1-beta interleukin and had the maximally high concentrations of this interleukin in the blood serum. A rise in the production of the pro-inflammatory mediator (IL-6) was found to be related to the severity of the inflammatory process in the middle ear. The TNF-alpha content in the patients with CSOM during the active period of the disease proved to increase by a factor of 6 in comparison with that in the subjects of the control group irrespective of the type of mutation.

    Malignant external otitis (MEO) is a potentially fatal otitis occurring in diabetic and immunosuppressed patients, which may cause cranial nerve palsies and massive thrombophlebitis of the brain. We studied five diabetic patients with the clinical diagnosis of external otitis who were suspected of having MEO and one diabetic patient presumed cured from MEO. All of them underwent methylene diphosphonate, nanocolloid and gallium single-photon emission tomography studies with quantitative analysis on the basis of regions of interest and count profile curves. This combined assessment helped us to diagnose and follow-up soft tissue and temporal bone infection, especially in the case of transsphenoidal extension of the disease, since conventional radiology and computed tomography were of no particular help. On the basis of these results, we consider scintigraphic demonstration of skull base infection as a fourth criterion of MEO given that the classical Chandler's triad (diabetes, granuloma, and Pseudomonas aeruginosa) is not always present.

    Introduction  Otitis Externa is common ear infection with a prevalence of 1%. Objective  The objective of this study is to evaluate the clinical and microbiological efficacy and safety profile with oral ciprofloxacin in the external bacterial otitis (EBO) management. Methods  This is a prospective observational study conducted with EBO outpatients referred to the otorhinolaryngology center in Moscow between March and August 2013. Our study included patients from two cohorts, acute external bacterial otitis (AEBO) - Group 1 - and exacerbation of chronic otitis externa (CEBO) - Group 2. We administered Ciprofloxacin 500 mg twice daily with standard topical EBO treatment for up to 10 days. Patients underwent evaluation on study visit days 1, 3, 5, and 10 for the severity. Bacteriological examination of ear canal cultures took place on Day 1 and Day 10. Results  We collected data from 60 EBO outpatients (AEBO: N  = 30 and CEBO: N  = 30). Swimming was the major risk factor associated with the disease in addition to the most common pathogenic organisms - Staphylococcus aureus and Pseudomonas aeruginosa . was We attained complete resolution of the inflammatory process in 28 (93%) and 27 (90%) patients in the AEBO and CEBO group, respectively. We confirmed this by microbiological test with almost complete eradication of the causative organisms. Overall, we observed good positive dynamics of ear canal with no major side effects. Conclusion  We found that Ciprofloxacin 500 mg, when administered orally twice daily for 7 to 10 days in otitis externa patients is clinically and microbiologically effective and comparatively safer than other antimicrobials.

  2. Otitis media with effusion: benefits and harms of strategies in use for treatment and prevention.

    Otitis media with effusion (OME) is a common clinical condition that is associated with hearing loss. It can be diagnosed at least once in approximately 80% of preschool children: 30-40% of them have recurrent episodes, and 5-10% have chronic disease. OME, in recurrent and persistent cases, might significantly delay or impair communication skills, resulting in behavioral and educational difficulties. Several therapeutic approaches have been used to avoid these problems. Most, however, have not been adequately studied, and no definitive conclusions can be drawn. Official guidelines do not recommend the use of decongestants, antihistamines, steroids, or antibiotics. The data are too scanty to assess other interventions, although autoinflation, because it incurs neither cost nor adverse events, deserves attention. Surgical procedures (i.e., tympanostomy tube insertion and adenoidectomy as an adjuvant) can be useful in some cases. This review evaluates all the current OME treatments and preventive measures, including their possible adverse events.

  3. Secretory products of helminth parasites as immunomodulators.

    2014-07-01

    Parasitic helminths release molecules into their environment, which are generally referred to as excretory-secretory products or ES. ES derived from a wide range of nematodes, trematodes and cestodes have been studied during the past 30-40 years, their characterization evolving from simple biochemical procedures such as SDS-PAGE in the early days to sophisticated proteomics in the 21st century. Study has incorporated investigation of ES structure, potential as vaccines, immunodiagnostic utility, functional activities and immunomodulatory properties. Immunomodulation by ES is increasingly the area of most intensive research with a number of defined helminth products extensively analyzed with respect to the nature of their selective effects on cells of the immune system as well as the molecular mechanisms, which underlie these immunomodulatory effects. As a consequence, we are now beginning to learn the identities of the receptors that ES employ and are increasingly acquiring detailed knowledge of the signalling pathways that they interact with and subvert. Such information is contributing to the growing idea that the anti-inflammatory properties of a number of ES products makes them suitable starting points for the development of novel drugs for treating human inflammatory disease.

    Acute otitis media (AOM) is one of the most common diseases in early infancy and childhood. Antibiotic use for AOM varies from 56% in the Netherlands to 95% in the USA, Canada and Australia. This is an update of a Cochrane review first published in The Cochrane Library in Issue 1, 1997 and previously updated in 1999, 2005, 2009 and 2013. To assess the effects of antibiotics for children with AOM. We searched CENTRAL (2015, Issue 3), MEDLINE (1966 to April week 3, 2015), OLDMEDLINE (1958 to 1965), EMBASE (January 1990 to April 2015), Current Contents (1966 to April 2015), CINAHL (2008 to April 2015) and LILACS (2008 to April 2015). Randomised controlled trials (RCTs) comparing 1) antimicrobial drugs with placebo and 2) immediate antibiotic treatment with expectant observation (including delayed antibiotic prescribing) in children with AOM. Two review authors independently assessed trial quality and extracted data. For the review of antibiotics against placebo, 13 RCTs (3401 children and 3938 AOM episodes) from high-income countries were eligible and had generally low risk of bias. The combined results of the trials revealed that by 24 hours from the start of treatment, 60% of the children had recovered whether or not they had placebo or antibiotics. Pain was not reduced by antibiotics at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01) but almost a third fewer had residual pain at two to three days (RR 0.70, 95% CI 0.57 to 0.86; number needed to treat for an additional beneficial outcome (NNTB) 20). A quarter fewer had pain at four to seven days (RR 0.76, 95% CI 0.63 to 0.91; NNTB 16) and two-thirds fewer had pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7) compared with placebo. Antibiotics did reduce the number of children with abnormal tympanometry findings at two to four weeks (RR 0.82, 95% CI 0.74 to 0.90; NNTB 11), at six to eight weeks (RR 0.88, 95% CI 0.78 to 1.00; NNTB 16) and the number of children with tympanic

    Otitis media with effusion (OME) is the most common cause of hearing loss in children, and tympanostomy (ear tube insertion) to alleviate the condition remains the commonest surgical intervention in children in the developed world. Chronic and recurrent forms of otitis media (OM) are known to have a very substantial genetic component; however, until recently, little was known of the underlying genes involved. The Jeff mouse mutant carries a mutation in the Fbxo11 gene, a member of the F-box family, and develops deafness due to a chronic proliferative OM. We previously reported that Fbxo11 is involved in the regulation of transforming growth factor beta (TGF-β) signalling by regulating the levels of phospho-Smad2 in the epithelial cells of palatal shelves, eyelids and airways of the lungs. It has been proposed that FBXO11 regulates the cell's response to TGF-β through the ubiquitination of CDT2. Additional substrates for FBXO11 have been identified, including p53. Here, we have studied both the genetic and biochemical interactions between FBXO11 and p53 in order to better understand the function of FBXO11 in epithelial development and its potential role in OM. In mice, we show that p53 (also known as Tp53) homozygous mutants and double heterozygous mutants (Jf/+ p53/+) exhibit similar epithelial developmental defects to Fbxo11 homozygotes. FBXO11 and p53 interact in the embryonic lung, and mutation in Fbxo11 prevents the interaction with p53. Both p53 and double mutants show raised levels of pSMAD2, recapitulating that seen in Fbxo11 homozygotes. Overall, our results support the conclusion that FBXO11 regulates the TGF-β pathway in the embryonic lung via cross-talk with p53. © 2015. Published by The Company of Biologists Ltd.

    To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions. Literature review. Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeable Haemophilus influenzae and Streptococcus pneumoniae predominate, with Moraxella catarrhalis, Staphylococcus aureus and Streptococcus pyogenes isolated in a lower proportion of samples. Alloiococcus otitidis was detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children. Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities ('microbiomes') of samples obtained from Indigenous children with otitis media.

    2017-12-01

    Full Text Available The external otitis is defined as an inflammation of the dog external ear canal and it is considered a common disease in dogs. It is a disease of multifactorial etiology, where one of the main microrganisms associated to the illness is the Malassezia ssp. Therefore, this work aimed to determine the frequency of Malassezia spp. by auricular cytology in dogs that present clinical signs of external otitis. Were used 23 dogs attended in a veterinary clinic located in Sinop-MT. The material was collected using a dry swab, where each extremity was inserted in one of the auditory canal (right and left, which was rotated, removed from the ear and rolled on the glass slide. First the glass slide was microscopically observed (objective 4X, for viewing mites, and then, the sample was fixed by heat and stained with Panoptic. Once stained, the glass slide was examined (objective 40X and 100X. Among the 23 dogs evaluated, 60.9% were positive for Malassezia spp., 8.7% were positive for the Otodectes cynotis mite, and also 30,4% of the animals showed mixed infection with Malassezia ssp. and bacteria. With this study, it can be concluded that Malassezia ssp. was found more frequently in at the auditory canal of dogs with that presents external otitis, associated or acting alone, indicating the importance of this yeast in cases of otitis.

    The swimmer's otitis or acute otitis externa, is a pathology that often occurs in those who practice swimming at a competitive level. The same problem often occurs in the summer with the attendance of swimming pools and bathing areas. A survey made in the United States in 2007 confirms the dynamics of the onset of this pathology, because the contamination of fungi and bacteria in the waters of the swimming pools and the sea cause the inflammation of the epithelium of the auditory canal. To face this issue, in addition to a correct diagnosis, and the necessary and appropriate therapies, it may follow the use of these medicinal preparations. The first one (A) is protective-acting, the second one (B) is characterized as a preventive, hygroscopic, moistening, antiseptic and antimycotic-acting solution. Swimmers who have been using the two (pre-and post) preparations daily for about a year have reported sporadic episodes of otitis. However, there is no doubt that these two compounds deserve a meticulous clinical trial in order to confirm their preventive and therapeutic potentials in external acute otitis.

    To evaluate the effects of otitis media with effusion on surgical parameters, patient safety, perioperative and postoperative complications. Total 890 children who underwent cochlear implantation between 2006 and 2015 were included. The ages ranged from 12 months to 63 months (mean: 32 months). The patients were divided into two groups according to the presence or absence of otitis media with effusion; otitis media with effusion group and non-otitis media group. Of 890 children, 105 had otitis media with effusion prior to surgery. In non-otitis media with group, there were 785 children. The average duration of surgery was 60min (ranged from 28 to 75min) in non-otitis media group, and 90min (ranged from 50 to 135min) in otitis media with effusion group (peffusion during the surgery. There was no significant difference between the complications of groups with or without otitis media with effusion (p>0.05). In 5 of 105 patients, there was a ventilation tube inserted before cochlear implantation, which did not change the outcome of implantation. There is no need for surgical treatment for otitis media with effusion before implantation since otitis media with effusion does not increase the risks associated with cochlear implantation. Operation duration is longer in the presence of otitis media with effusion. However, otitis media with effusion leads to intraoperative difficulties like longer operation duration, bleeding, visualization of the round window membrane, cleansing the middle ear granulations as well as mastoid and petrous air cells.

    2002-01-01

    The biogenesis of secretory lysosomes, which combine characteristics of both lysosomes and secretory granules, is currently of high interest. In particular, it is not clear whether delivery of membrane proteins to the secretory lysosome requires lysosomal, secretory granule, or some novel targeting determinants. Heterologous expression of P-selectin has established that this membrane protein contains targeting signals for both secretory granules and lysosomes. P-selectin is therefore an ideal...

    ERp44 is a pH-regulated chaperone of the secretory pathway. In the acidic milieu of the Golgi, its C-terminal tail changes conformation, simultaneously exposing the substrate-binding site for cargo capture and the RDEL motif for ER retrieval through interactions with cognate receptors. Protonation of cysteine 29 in the active site allows tail movements in vitro and in vivo. Here, we show that conserved histidine residues in the C-terminal tail also regulate ERp44 in vivo. Mutants lacking these histidine residues retain substrates more efficiently. Surprisingly, they are also O-glycosylated and partially secreted. Co-expression of client proteins prevents secretion of the histidine mutants, forcing tail opening and RDEL accessibility. Client-induced RDEL exposure allows retrieval of proteins from distinct stations along the secretory pathway, as indicated by the changes in O-glycosylation patterns upon overexpression of different partners. The ensuing gradients might help to optimize folding and assembly of different cargoes. Endogenous ERp44 is O-glycosylated and secreted by human primary endometrial cells, suggesting possible pathophysiological roles of these processes. © 2014.

    A secretory structure is a structure that produces a plant's metabolite substances. Secretory structures are grouped into an internal and external. Zingiberaceae plants are known as traditional medicine plants and as spice plants due to secretory structures in their tissues. The objective of the research were to describe the secretory structure of Zingiberaceae plants and to discover the qualitatively primary metabolite substances in plant's tissues via histochemistry test. The research was conducted by observation descriptive design, quantitative data including the density of secretory cells per mm². The quantitative data were analyzed by ANOVA and continued by Duncan at α = 5 %. The results showed that the secretory structures in leaves, rhizome, and the root of 14 species of Zingiberaceae plants are found in the mesophyll of leaves and cortex, and also pith in rhizome and roots. The type of secretory structure is internal. Within the root of Zingiber cassumunar Roxb.(bengle), Curcuma domestica Val. (kunyit), Curcuma zedoaria (Berg.) Roscoe (kunyit putih), Zingiber zerumbet (L.) J.E. Smith (lempuyang), Alpiniapurpurata K. Schum (lengkuas merah), and Curcuma aeruginosa Val. (temu ireng) were found amylum grains, while in Kaemferia galanga L. (kencur), Boesen bergiapandurata L. (temu kunci), and Curcuma xanthorrhiza Roxb. (temulawak) there were no amylum grains in the root as well as in the leaves. The roots of bengle had the greatest density of amylum grain, it had 248.1 ± 9.8 secretory cells of amylum grains per mm². Lipids (oil droplets) were found in the root of bengle, Zingiber officinale Roxb. Var. emprit (jahe emprit), Zingiber officinale Roxb. Var. Gajah (jahe gajah), Zingiber officinale Roxb. Var. Rubrum (jahe merah), Keampferia angustifolia L. (kunci pepet), kunyit, kunyit putih, lempuyang, lengkua smerah, Curcuma aeruginosa Val.

    Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.

    The assessment of impact and evaluation of treatment effects in chronic otitis media (OM) calls for a much broader approach than just examining the presence of middle ear effusion or hearing loss. It is increasingly recognised that this condition may result in a comprised quality of life. Several studies have used proxy completed questionnaires to objectify the illness experience associated with chronic OM. To review questionnaires which have been developed to describe the effects of chronic OM on the daily functioning of children. Psychometric properties have been evaluated, in addition to discriminative and evaluative qualities. A systematic review of publications pertaining to developed questionnaires related with chronic OM. Systematic literature searches of PubMed (1966-January 2007) and EMBASE (1989-January 2007) were conducted, supplemented by using free text words to identify publications after January 2005. The included 15 questionnaires were developed for children with recurrent or persistent OM, describing functional health status (FHS), while two questionnaires also evaluate the effect of tympanostomy tubes insertion. The questionnaires generally cover six impact areas (physical symptoms, child development, educational performance, emotional/practical burden and general health status) with physical symptoms being the most prominant. The OM8-30, OMO-22 and OM-6 adequately reflect the multidimensional aspects of FHS in chronic OM. The OMO-22 and OM8-30 show the best psychometric properties for the discrimination of impact severity between children, while the OM-6 was found to have the best qualities for the evaluation of clinical change. Clinical applicability is crucial for the assessment of FHS in chronic OM, but requires a trade-off with necessary psychometric properties.

    To review the literature involving complementary and alternative medicine (CAM) for pediatric otitis media. Multiple modalities are discussed, including prevention involving breastfeeding, nutrition, and vaccination; symptomatic treatment involving homeopathy, natural health products, and probiotics; manual manipulations involving osteopathy and chiropractics; and traditional Chinese and Japanese medicine. The information presented will assist physicians in advising patients on their decision-making during the early stages of otitis media when antibiotics and surgery are not yet indicated. A systematic literature search was conducted through January 2012 in PubMed using MESH term "otitis media" in conjunction with "complementary therapies," "homeopathy," "manipulation, osteopathic," "manipulation, chiropractic," "acupuncture therapy," "probiotics," "naturopathy," and "xylitol." Theses searches yielded 163 unique results. Abstracts and titles were evaluated for relevance. Case reports, case series, randomized controlled trials, and basic science research were included. Publications not relevant to the discussion of alternative medicine in otitis media were excluded. Bibliographies were checked for further publications. Thirty-six unique publications were reviewed. Of all therapies in complementary and alternative medicine, only xylitol has been studied in well-designed, randomized, blinded trials; it is likely effective, but compliance limits its applicability. Management of acute otitis media begins with watchful waiting. Herbal eardrops may help relieve symptoms. Homeopathic treatments may help decrease pain and lead to faster resolution. Prevention should be emphasized with elimination of risk factors, such as second hand smoke and bottle-feeding, as well as maintaining nutrition and vaccinations. Vitamin supplementation may be helpful. Probiotics and xylitol may be beneficial as well. Traditional Chinese/Japanese therapies show promising results but remain

    The purpose of this study was to compare computed tomography (CT) and radiography in the identification of canine middle ear disease. Fourteen canine patients underwent a radiographic “bullae series” and CT examination of the tympanic bullae. Confirmation of otitis media was based on surgery. The overall diagnostic accuracy of CT and radiographs regarding the diagnosis of otitis media was similar. Although a marked difference was not detected between radiographs and CT for detecting otitis media using Youden's index values, CT was a more sensitive test for the detection of otitis media

    Aspergillus spp. are saprophytic opportunistic fungal organisms and are a common cause of otomycosis in humans. Although there have been case reports of Aspergillus otitis externa in dogs, to the best of the authors' knowledge, this is the first retrospective case series describing Aspergillus otitis in dogs and cats. To characterize signalment, putative risk factors, treatments and outcomes of a case series of dogs and cats with Aspergillus otitis. Eight dogs and nine cats diagnosed with Aspergillus otitis. A retrospective review of medical records from 1989 to 2014 identified animals diagnosed with Aspergillus otitis based on culture. All dogs weighed greater than 23 kg. The most common putative risk factors identified in this study were concurrent diseases, therapy causing immunosuppression or a history of an otic foreign body. Aspergillus otitis was unilateral in all study dogs and most cats. Concurrent otitis media was confirmed in three dogs and one cat, and suspected in two additional cats. Aspergillus fumigatus was the most common isolate overall and was the dominant isolate in cats. Aspergillus niger and A. terreus were more commonly isolated from dogs. Animals received various topical and systemic antifungal medications; however, otic lavage under anaesthesia and/or surgical intervention increased the likelihood of resolution of the fungal infection. Aspergillus otitis is uncommon, typically seen as unilateral otitis externa in cats and larger breed dogs with possible risk factors that include immunosuppression and otic foreign bodies; previous antibiotic usage was common. © 2015 ESVD and ACVD.

    Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term. This cohort was used to investigate whether children with PCD and OME not treated with VT were predisposed to cholesteatoma formation in the setting of a paediatric quaternary referral centre. A retrospective chart review was performed of all the children attending a multi-disciplinary PCD clinic at a national quaternary referral centre with a diagnosis of OME. We reviewed otoscopic findings, and audiometry and tympanometry results. We assessed the children in four groups: Watchful waiting, hearing aids, VT, and VT and hearing aids. One-hundred-and-one of 107 patients included in the study had a diagnosis of otitis media with effusion. No child with OME and PCD was diagnosed with a cholesteatoma during the follow up period. The only children who had insertion of a ventilatory tube were those who had the procedure prior to the formal diagnosis of PCD. We found a significant complication rate in the children with VT insertion. Hearing improved over time. The prevalence of retraction pockets in untreated OME was 1.72% (3 out of 174 ears). In children with PCD, OME is an almost universal finding in younger children, but not in adolescents. The study supports the current preference to avoid VT insertion in children with PCD as it confers a significantly higher rate of complications. No cases of cholesteatoma were found in this cohort of PCD children with OME managed without VTs. Crown Copyright © 2017. Published by Elsevier B

    Full Text Available A 40-year-old female presented with purulent exudate through the left auditive duct and pain in the left ear region, which intensified during mastication. After collection of the pus from the left ear lesion, amoxicillin-clavulanic acid for seven days was prescribed for a presumed diagnosis of acute otitis. Four days later, the pus culture grew V. fluvialis which is further identified by API 20E identification system (bioMérieux. Following the successful completion of a course of antibiotics, the patient recovered completely and without complication. To the best of our knowledge, this is the first case of Vibrio fluvialis otitis after swimming in an immunocompetent patient.

    Full Text Available In this study one hundred Awassi sheep were examined clinically and bacteriologically for isolation and identification of the bacterial agents of otitis externa in sheep. The main clinical signs appeared included weakness, pale mucus membrane, auricular discharge, cough, anorexia, emaciation, and nasal discharge. Results revealed isolation of bacteria from (45% examined swabs. The most being from right ear. Younger animals were more frequently infected than older animals. Pseudomonas aeruginosa, Staphylococcus aureus, Mannheimia haemolytica, Staph. epidermidis, Pasteurella multocida, Streptococcus spp., Acintobacter spp., Escherichia coli and Klebsiella pneumonia were isolated. The results revealed that the most bacterial isolates were resistance to the bactericidal effect of the normal serum included Streptococcus pneumonia, Staphylococcus aureus, Mannheimia haemolytica. While the most bacterial isolates were produced hydroxymate siderophore included Staphylococcus aureus, Mannheimia haemolytica, Streptococcus pneumonia. The obtained results indicated to the importance of determination of serum resistance as a bacterial virulence factor in otitis externa in sheep.

    Two types of oviductal epithelial cells, secretory and ciliated, play crucial roles in the first days after fertilization in mammals. Secretory cells produce various molecules promoting embryo development, while ciliated cells facilitate transport of oocytes and zygotes by ciliary beating. The proportions of the two cell types change during the estrous cycle. The proportion of ciliated cells on the oviductal luminal surface is abundant at the follicular phase, whereas the proportion of secretory cells gradually increases with the formation of the corpus luteum. In the present study, we hypothesize that the proportions of ciliated and secretory epithelial cells are regulated by mitosis. The proportion of the cells being positive for FOXJ1 (a ciliated cell marker) or Ki67 (a mitosis marker) in epithelial cells during the estrous cycle were immunohistochemically examined. Ki67 and FOXJ1 or PAX8 (a secretory cell marker), were double-stained to clarify which types of epithelial cells undergo mitosis. In the ampulla, the percentage of FOXJ1-positive cells was highest at the day of ovulation (Day 0) and decreased by about 50 % by Days 8-12, while in the isthmus it did not change during the estrous cycle. The proportion of Ki67-positive cells was highest at around the time of ovulation in both the ampulla and isthmus. All the Ki67-positive cells were PAX8-positive and FOXJ1-negative in both the ampulla and isthmus. These findings suggest that epithelial remodeling, which is regulated by differentiation and/or proliferation of secretory cells of the oviduct, provides the optimal environment for gamete transport, fertilization and embryonic development.

    We describe two cases of tuberculous otitis media studied with high-resolution computed tomography (CT). Findings included extensive soft tissue densities with fluid levels in the tympanic cavity, the antrum, the mastoid and petrous air cells. Multifocal bony erosions and reactive bone sclerosis were seen as well. CT proved valuable for planning therapy by accurately displaying the involvement of the various structures of the middle and inner ear. However, the specific nature of the disease could only be presumed. (orig.)

  19. A mutation in Nischarin causes otitis media via LIMK1 and NF-κB pathways.

    Full Text Available Otitis media (OM, inflammation of the middle ear (ME, is a common cause of conductive hearing impairment. Despite the importance of the disease, the aetiology of chronic and recurrent forms of middle ear inflammatory disease remains poorly understood. Studies of the human population suggest that there is a significant genetic component predisposing to the development of chronic OM, although the underlying genes are largely unknown. Using N-ethyl-N-nitrosourea mutagenesis we identified a recessive mouse mutant, edison, that spontaneously develops a conductive hearing loss due to chronic OM. The causal mutation was identified as a missense change, L972P, in the Nischarin (NISCH gene. edison mice develop a serous or granulocytic effusion, increasingly macrophage and neutrophil rich with age, along with a thickened, inflamed mucoperiosteum. We also identified a second hypomorphic allele, V33A, with only modest increases in auditory thresholds and reduced incidence of OM. NISCH interacts with several proteins, including ITGA5 that is thought to have a role in modulating VEGF-induced angiogenesis and vascularization. We identified a significant genetic interaction between Nisch and Itga5; mice heterozygous for Itga5-null and homozygous for edison mutations display a significantly increased penetrance and severity of chronic OM. In order to understand the pathological mechanisms underlying the OM phenotype, we studied interacting partners to NISCH along with downstream signalling molecules in the middle ear epithelia of edison mouse. Our analysis implicates PAK1 and RAC1, and downstream signalling in LIMK1 and NF-κB pathways in the development of chronic OM.

    The objective of the present study was to elucidate the specific features of the clinical course of acute otitis media as well as the peculiarities of the vestibular function and the microbial paysage associated with this pathological condition under the present-day conditions. The study included 135 patients presenting with acute otitis media (AOM) at different stages of the disease. The discharge obtained from the tympanic cavity of all the patients was examined with the use of polymerase chain reaction in real time, audiological and vestibulogical methods. The distinctive features of acute otitis medium associated with Streptococcus pneumoniae infection were found to be the intense pain syndrome with the symptoms of intoxication, well apparent inflammatory changes in the tympanic membrane as revealed by otoscopy, the increased frequency of sensorineural impairment of hearing, and the characteristic type B tympanometric curve. Typical of AOM associated with Haemophilus influenza infection are the mild pain syndrome, weak changes in the tympanic membrane as revealed by otoscopy, conductive hearing loss, and the type C tympanometric curve.

    A healthy 60-year-old male was initially treated for external otitis, and subsequently received multiple surgeries including abscess drainage, temporal bone debridement, canaloplasty of the external auditory meatus, and fistula excision and was treated with numerous antibiotics at another hospital over a 1-year period. He was seen at our hospital on February 14, 2014 with a complaint of a non-healing wound behind the left ear and drainage of purulent fluid. He had no history of diabetes mellitus or compromised immune function. Computed tomography (CT) and magnetic resonance imaging (MRI) studies at our hospital showed osteomyelitis involving the left temporal, occipital, and sphenoid bones, the mandible, and an epidural abscess. Routine blood testing and tests of immune function were normal, and no evidence of other infectious processes was found. He was diagnosed with malignant otitis externa (MOE). Bone debridement and incision and drainage of the epidural abscess were performed, and vancomycin was administered because culture results revealed Corynebacterium jeikeium, Corynebacterium xerosis, and Enterococcus faecalis. MOE should be considered in healthy patients with external otitis who fail initial treatment.

    There is an increased recovery of Fusobacterium necrophorum from cases of otitis media and mastoiditis in the pediatric population. These infections may be highly severe, causing local osteomyelitis, bacteremia, and Lemierre's syndrome. The severity and difficulties in providing optimal treatment for these infections may be especially difficult in this age group due to immunological immaturity and delayed presentation. In this review of literature, we present and analyze the clinical presentation, management, and outcome of otic infections caused by F. necrophorum in infants and young toddlers less than 2 years old. Search in Pubmed was conducted for reported cases in the English literature for the time period of the last 50 years. Twelve well-described cases were retrieved with F. necrophorum otitis and mastoiditis and complications reported in all cases. Treatment included both intravenously with antimicrobial agents (beta lactams plus metronidazole) and mastoidectomy. Lemierre's syndrome and Lemierre's syndrome variants developed in 60 % of the patients. Dissemination of the infection as distal osteomyelitis and septic shock were also reported. The outcome was favorable in all the cases. Otitis and mastoiditis infections in children less then 2 years old are invasive infections, and severe complications can occur.

  3. Human evolutionary history: consequences for the pathogenesis of otitis media.

    2010-12-01

    The pathogenesis of otitis media is multifactorial, but the role of evolution on its development has not been addressed. We posit that the high prevalence of middle-ear disease is most likely restricted to humans, in contrast to other wild species, because the associated hearing loss would have reduced the fitness of affected individuals as a result of predation. We present here the possible consequences of two human adaptations that may have resulted in ubiquitous otitis media: the interaction of bipedalism and increased brain size, and the loss of facial prognathism resulting from speech or cooking. As a consequence of our adaptation for bipedalism, the female pelvic outlet is constricted, which, in the context of a rapidly enlarging brain, results in humans being born 12 months too soon. Significantly, immature eustachian tube structure and function, in conjunction with an immature immune system, helps to explain the high incidence of otitis media in the first year of life. But the persistence of middle-ear disease beyond this stage is not explained by "immaturity." The morphology of the palate changed with the adaptations that produced facial flattening, with concomitant effects on eustachian tube function. These changes resulted in relatively poor human physiologic tubal function in comparison to the nonhuman primate. Copyright © 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

    Full Text Available PURPOSE: Dry eye syndrome is a multifactorial chronic disabling disease mainly caused by the functional disruptions in the lacrimal gland. The treatment involves palliation like ocular surface lubrication and rehydration. Cell therapy involving replacement of the gland is a promising alternative for providing long-term relief to patients. This study aimed to establish functionally competent lacrimal gland cultures in-vitro and explore the presence of stem cells in the native gland and the established in-vitro cultures. METHODS: Fresh human lacrimal gland from patients undergoing exenteration was harvested for cultures after IRB approval. The freshly isolated cells were evaluated by flow cytometry for expression of stem cell markers ABCG2, high ALDH1 levels and c-kit. Cultures were established on Matrigel, collagen and HAM and the cultured cells evaluated for the presence of stem cell markers and differentiating markers of epithelial (E-cadherin, EpCAM, mesenchymal (Vimentin, CD90 and myofibroblastic (α-SMA, S-100 origin by flow cytometry and immunocytochemistry. The conditioned media was tested for secretory proteins (scIgA, lactoferrin, lysozyme post carbachol (100 µM stimulation by ELISA. RESULTS: Native human lacrimal gland expressed ABCG2 (mean±SEM: 3.1±0.61%, high ALDH1 (3.8±1.26% and c-kit (6.7±2.0%. Lacrimal gland cultures formed a monolayer, in order of preference on Matrigel, collagen and HAM within 15-20 days, containing a heterogeneous population of stem-like and differentiated cells. The epithelial cells formed 'spherules' with duct like connections, suggestive of ductal origin. The levels of scIgA (47.43 to 61.56 ng/ml, lysozyme (24.36 to 144.74 ng/ml and lactoferrin (32.45 to 40.31 ng/ml in the conditioned media were significantly higher than the negative controls (p<0.05 for all comparisons. CONCLUSION: The study reports the novel finding of establishing functionally competent human lacrimal gland cultures in-vitro. It also

    Full Text Available Abstract Background Aboriginal children in remote Australia have high rates of complicated middle ear disease associated with Streptococcus pneumoniae and other pathogens. We assessed the effectiveness of pneumococcal vaccination for prevention of otitis media in this setting. Methods We compared two birth cohorts, one enrolled before (1996–2001, and the second enrolled after introduction of 7-valent pneumococcal conjugate and booster 23-valent polysaccharide vaccine (2001–2004. Source populations were the same for both cohorts. Detailed examinations including tympanometry, video-recorded pneumatic otoscopy and collection of discharge from tympanic membrane perforations, were performed as soon as possible after birth and then at regular intervals until 24 months of life. Analyses (survival, point prevalence and incidence were adjusted for confounding factors and repeated measures with sensitivity analyses of differential follow-up. Results Ninety-seven vaccinees and 51 comparison participants were enrolled. By age 6 months, 96% (81/84 of vaccinees and 100% (41/41 of comparison subjects experienced otitis media with effusion (OME, and by 12 months 89% and 88% experienced acute otitis media (AOM, 34% and 35% experienced tympanic membrane perforation (TMP and 14% and 23% experienced chronic suppurative otitis media (CSOM. Age at the first episode of OME, AOM, TMP and CSOM was not significantly different between the two groups. Adjusted incidence of AOM (incidence rate ratio: 0.88 [95% confidence interval (CI: 0.69–1.13] and TMP (incidence rate ratio: 0.63 [0.36–1.11] was not significantly reduced in vaccinees. Vaccinees experienced less recurrent TMP, 9% (8/95 versus 22% (11/51, (odds ratio: 0.33 [0.11–1.00]. Conclusion Results of this study should be interpreted with caution due to potential bias and confounding. It appears that introduction of pneumococcal vaccination among Aboriginal infants was not associated with significant changes

  10. Recurrent malignant otitis externa with multiple cranial nerve involvement: A case report

    Directory of Open Access Journals (Sweden)

    Đerić Dragoslava

    2016-01-01

    Full Text Available Introduction. Necrotizing otitis externa is a rare but conditionally fatal infection of external auditory canal with extension to deep soft tissue and bones, resulting in necrosis and osteomyelitis of the temporal bone and scull base. This condition is also known as malignant otitis due to an aggressive behavior and poor treatment response. Early diagnosis of malignant otitis is a difficult challenge. We present an illustrative case of necrotizing otitis externa and suggest some strategies to avoid diagnostic and treatment pitfalls. Case Outline. A 70-year-old patient presented with signs of malignant otitis externa, complicated by peripheral facial palsy. Adequate diagnostic and treatment procedures were performed with clinical signs of resolution. The recurrence of malignant infection had presented three months after previous infection with multiple cranial nerve neuropathies and signs of jugular vein and lateral sinus thrombosis. An aggressive antibiotic treatment and surgery were carried out, followed by substantial recovery of the patient and complete restoration of cranial nerves’ functions. Conclusion. Necrotizing otitis externa is a serious condition with uncertain prognosis. The suspicion of malignant external otitis should be raised in cases of resistance to topical treatment, especially in patient with predisposing factors. Evidence-based guideline for necrotizing otitis externa still doesn’t exist and treatment protocol should be adjusted to individual presentation of each patient.

  11. [The clinical classification of acute otitis media with special reference to tympanometry].

    Science.gov (United States)

    Subbotina, M V

    We have developed a new clinical classification of acute otitis media (AOM) based on the previously proposed classifications of V.T. Palchun with co-workers (1997) and J. Jeger (1970) in which the letter near the stage of the pathological process roughly corresponds to the type of the tympanogram as follows: stage I (acute tubootitis): A, B, C; stage II (acute catarrhal otitis media): A, B, C; stage III (acute purulent otitis media, perforation stage); stage IV (acute purulent otitis media, post-perforation stage); stage V (resolution of otitis media): A - convalescence or recovery, B1 - exudate present in the tympanic cavity; B2 - persisting perforation; C - block of the auditory tube, O - the development of complications. This classification implies the necessity of tympanometry at the stage of diagnostics of AOM although it is not mandatory because the detection of exudate as a result of paracentesis at any of the stages of otitis media will allow to designate the stage of otitis either by letter A, B or C. The application of the new classification described in this article permits to more accurately than before determine the character of the pathological process in the middle ear during the course of acute otitis media which is of special importance in the clinical pediatric practice for the timely and adequate treatment of the children.

    Acute otitis media causes discomfort to children and inconvenience to their parents. This study evaluated the quality of life in children with recurrent acute otitis media aged less than 24 months. Quality of life was evaluated in 149 children aged 10 to 24 months who were referred to the Oulu University Hospital on account of recurrent acute otitis media. The children were treated with or without surgery. Age-matched controls were selected randomly from the general child population. Parents completed the Child Health Questionnaire. The children with recurrent acute otitis media had a significantly poorer quality of life than control children. The control children with a history of a few acute otitis media episodes had a significantly poorer quality of life than those without any such history. The quality of life of the children with recurrent acute otitis media improved during the one-year follow up, regardless of the treatment, but did not reach the same level as healthy children. Acute otitis media detracted from quality of life when a generic measure was used. The mode of treatment used to prevent further recurrences of acute otitis media did not influence quality of life improvement.

    Notch signaling largely determines intestinal epithelial cell fate. High Notch activity drives progenitors toward absorptive enterocytes by repressing secretory differentiation programs, whereas low Notch permits secretory cell assignment. Myeloid translocation gene-related 1 (MTGR1) is a transcriptional corepressor in the myeloid translocation gene/Eight-Twenty-One family. Given that Mtgr1(-/-) mice have a dramatic reduction of intestinal epithelial secretory cells, we hypothesized that MTGR1 is a key repressor of Notch signaling. In support of this, transcriptome analysis of laser capture microdissected Mtgr1(-/-) intestinal crypts revealed Notch activation, and secretory markers Mucin2, Chromogranin A, and Growth factor-independent 1 (Gfi1) were down-regulated in Mtgr1(-/-) whole intestines and Mtgr1(-/-) enteroids. We demonstrate that MTGR1 is in a complex with Suppressor of Hairless Homolog, a key Notch effector, and represses Notch-induced Hairy/Enhancer of Split 1 activity. Moreover, pharmacologic Notch inhibition using a γ-secretase inhibitor (GSI) rescued the hyperproliferative baseline phenotype in the Mtgr1(-/-) intestine and increased production of goblet and enteroendocrine lineages in Mtgr1(-/-) mice. GSI increased Paneth cell production in wild-type mice but failed to do so in Mtgr1(-/-) mice. We determined that MTGR1 can interact with GFI1, a transcriptional corepressor required for Paneth cell differentiation, and repress GFI1 targets. Overall, the data suggest that MTGR1, a transcriptional corepressor well characterized in hematopoiesis, plays a critical role in intestinal lineage allocation. © FASEB.

  19. Otitis media in Greenland. Studies on historical, epidemiological, microbiological, and immunological aspects.

    Homøe, P

    2001-01-01

    This thesis describes the different aspects of otitis media (OM) in the population of Greenland viewed in a historical and modern clinical perspective. Chapter 1 outlines the addressed problems and aims while chapters 2 and 3 deal with historical studies and an evaluation of the present knowledge based on the literature. Physical anthropological studies, using skeletal samples of adult Eskimo crania from before and after the colonization of Greenland in 1721 and information about modern living Eskimos (Inuit), have shown that OM sequelae of the temporal bones were significantly less common in pre-colonization Eskimos and that the mean area size of the pneumatized cell system in the temporal bone was significantly larger in pre-colonization Eskimos. These findings indicated an increase in OM after the colonization most likely caused by the social, cultural, habitary, and dietary changes due to increased contact with the outside world. Historical reports after the colonization confirm a high prevalence of OM especially in children. Modern epidemiological studies from the 1960's to 1980's in the Arctic region of Alaska, Canada, and Greenland along with reports from visiting consultant otologists in Greenland almost uniformly mention prevalent OM problems in children as well as in adults. The aim was therefore to further describe the epidemiological pattern of the different OM disease entities (acute OM (AOM), chronic OM (COM), COM with suppuration (CSOM), secretory OM (SOM), and cholesteatoma) and investigate the potentially associated risk factors in especially Greenlandic children because these diseases are primarily established and problematical in childhood. Chapter 4 describes the definitions used in the thesis and chapter 5 describes the studies included. Section 5.1 describes a study of cholesteatoma in Greenlanders. The study revealed an almost similar incidence of hospital treated children with cholesteatoma (6.6 per 100,000) as seen in comparable studies

  20. Testing for Chronic Diarrhea.

    Raman, M

    Chronic diarrhea is a frequently encountered symptom in clinical practice. The etiologies for chronic diarrhea are diverse and broad with varying clinical implications. A useful method of categorizing chronic diarrhea to guide a diagnostic work-up is a pathophysiology-based framework. Chronic diarrhea may be categorized as malabsorptive, secretory, osmotic, and inflammatory or motility related. Frequently, overlap between categories may exist for any given diarrhea etiology and diagnostic testing must occur with an understanding of the differential diagnosis. Investigations to achieve a diagnosis for chronic diarrhea range from screening blood and stool tests to more directed testing such as diagnostic imaging, and endoscopic and histological evaluation. The pathophysiology-based framework proposed in this chapter will allow the clinician to select screening tests followed by targeted tests to minimize cost and complications to the patient, while providing a highly effective method to achieve an accurate diagnosis. © 2017 Elsevier Inc.

    To evaluate the clinical picture and microbiological findings of children hospitalized due to acute otitis media and to analyze how it differs from acute mastoiditis. A retrospective review of the medical records of all children (0-16 years) hospitalized due to acute otitis media in the Department of Otorhinolaryngology at the Helsinki University Hospital, between 2003 and 2012. Comparison with previously published data of children with acute mastoiditis (n=56) from the same institute and period of time. The most common pathogens in the children hospitalized due to acute otitis media (n=44) were Streptococcus pneumoniae (18%), Pseudomonas aeruginosa (16%), Streptococcus pyogenes (14%), and Staphylococcus aureus (14%). One of the most common pathogens of out-patient acute otitis media, Haemophilus influenzae, was absent. Otorrhea was common in infections caused by S. pyogenes and otorrhea via tympanostomy tube in infections caused by P. aeruginosa. In children under 2 years-of-age, the most common pathogens were S. pneumoniae (43%), Moraxella catarrhalis (14%), and S. aureus (7%). S. pyogenes and P. aeruginosa were only found in children over 2 years-of-age. Previous health problems, bilateral infections, and facial nerve paresis were more common in children hospitalized due to acute otitis media, compared with acute mastoiditis, but they also demonstrated lower CRP values and shorter duration of hospital stay. The number of performed tympanostomies and mastoidectomies was also comparatively smaller in the children hospitalized due to acute otitis media. S. aureus was more common and S. pneumoniae, especially its resistant strains, was less common in the children hospitalized due to acute otitis media than acute mastoiditis. Acute otitis media requiring hospitalization and acute mastoiditis compose a continuum of complicated acute otitis media that differs from common out-patient acute otitis media.

    BACKGROUND: Acute otitis media (AOM) is a common childhood illness and the leading indication for antibiotic prescriptions for US children. Xylitol, a naturally occurring sugar alcohol, can reduce AOM when given 5 times per day as a gum or syrup, but a more convenient dosing regimen is needed for widespread adoption. METHODS: We designed a pragmatic practice-based randomized controlled trial to determine if viscous xylitol solution at a dose of 5 g 3 times per day could reduce the occurrence of clinically diagnosed AOM among otitis-prone children 6 months through 5 years of age. RESULTS: A total of 326 subjects were enrolled, with 160 allocated to xylitol and 166 to placebo. In the primary analysis of time to first clinically diagnosed AOM episode, the hazard ratio for xylitol versus placebo recipients was 0.88 (95% confidence interval [CI] 0.61 to 1.3). In secondary analyses, the incidence of AOM was 0.53 episodes per 90 days in the xylitol group versus 0.59 in the placebo group (difference 0.06; 95% CI –0.25 to 0.13); total antibiotic use was 6.8 days per 90 days in the xylitol group versus 6.4 in the placebo group (difference 0.4; 95% CI –1.8 to 2.7). The lack of effectiveness was not explained by nonadherence to treatment, as the hazard ratio for those taking nearly all assigned xylitol compared with those taking none was 0.93 (95% CI 0.56 to 1.57). CONCLUSIONS: Viscous xylitol solution in a dose of 5 g 3 times per day was ineffective in reducing clinically diagnosed AOM among otitis-prone children. PMID:24394686

    Otitis media with effusion (OME) is a leading cause of difficulty in hearing in paediatric population. Otitis media with effusion must be detected and managed early to prevent conductive hearing loss in children. It was aimed to compare results of laser myringotomy and ventilation tube insertion, in terms of hearing improvement and recurrence of Middle ear effusion (MEE). This randomized controlled trial was conducted from February 2012 to January 2015. Children of 4- 12 years of age with decreased hearing due to OME were included in the study. These children were investigated with pure tone audiometry (PTA) and tympanometry to confirm conductive hearing loss. Patients were put in 2 groups, group one comprised of patients treated with laser myringotomy and group 2, treated with ventilation tube insertion. The objective was to evaluate and compare results of the two procedures in terms of resolution of middle ear effusion (MEE) and improvement of hearing. The two procedures were also compared in terms of complications like otorrhea, persistence of perforation, hypertrophic scar and thinning of tympanic membrane (TM). Middle ear effusion cleared in 35 out of 68 ears with laser myringotomy (LM) as compared to 52 out of 62 ears with ventilation tubes (VT). The myringotomy was still patent in 21 ears treated with LM while tube was in site in 50 years with VT after 3 months. The hearing level improved with LM by 10-15 dB after first 3 months. The aim in Otitis media with effusion is ventilation of tympanic cavity. Laser myringotomy can be substitute to ventilation tube insertion (VT). But it remains patent for shorter time and less effective than VT. The ears with refractory or recurrent MEE should have VT insertion.

    Middle and inner ear infections have been reported as a clinical entity in swine, other animal species and humans. In pigs, the anatomical-pathological and microbiological findings have been described. In this report, we describe radiographic findings in affected pigs. A total of 25 pigs with a head tilt and circling, as clinical signs of otitis media and interna, were examined. The majority were weaner-pigs with dyspnea or rhinitis. In radiographs, there was an increased opacity of the bulla tympanica, often accompanied by marginal destruction or thickening of the bulla wall. The radiographic findings confirmed the clinical diagnosis in each affected pig, but there were 5 false positive interpretations

    A case of transverse sinus thrombosis is described in an adolescent male with antecedent meningomyelocele corrected by surgery, and ventriclo-peritoneal derivation. Four months before the occurrence of thrombosis, he presented with bilateral otitis media and mastoiditis, and was treated with antibiotic. Magnetic resonance images were not obtained before referral to our hospital. The patient received full anticoagulation and his clinical course was uneventful. He remains asymptomatic under outpatient surveillance till this report. The aim of reporting the case is to emphasize the role of otologic infections in the origin of intracranial thrombotic phenomena, and highlights the findings of magnetic resonance venography for characterization of intracranial sinus thrombosis.

    The clinical efficiency of treatment was evaluated in 60 patients aged 18 to 60 years with protracted acute otitis media (AOM) who had residual tympanic membrane inflammation and exudates in the tympanic cavity. The patients were divided into 2 groups of 30 each, who received equal basic medical treatment; Group 1 patients were additionally given eurespal (fenspiride) 80 mg thrice daily for 2 weeks. The patients were examined by clinical, endoscopic, and audiometric studies; the transport function of the nasal ciliated epithelium was also explored. The findings suggest the benefits of the additional use of eurespal in the treatment of the catarrhal stage of AOM.

    The usefulness of radionuclear scanning in the treatment of 18 patients with necrotizing progressive ''malignant'' external otitis is discussed. A Tc 99-m bone scan, a valuable test since results are positive in early cases of osteomyelitis of the temporal bone and base of skull, showed increased uptake in all 18 patients. In 6 patients, Ga-67 citrate scans were obtained at the start of therapy and at 5-6 week intervals thereafter. The serial gallium scans were useful in evaluating the effectiveness of therapy since the uptake decrease with control of infection

    Technetium99m Methylene Diphosphate bone scintigraphy (BS) of the skull was performed in three patients with malignant external otitis (MEO). Pathological uptake of the radioisotope in the mastoid region was found during the early stages of MEO updating radiologic findings. The extent of the radioisotope accumulation during the early stages of MEO indicates that the actual tissue damage exceeds the clinical estimation. The follow-up BS findings correlate well with the clinical course of MEO indicating either healing or extension to the base of skull

    Full Text Available INTRODUCTION: Studies that compare the impact of different infectious entities of the male reproductive tract (MRT on the male accessory gland function are controversial. MATERIAL AND METHODS: Semen analyses of 71 patients with proven infections of the MRT were compared with the results of 40 healthy non-infected volunteers. Patients were divided into 3 groups according to their diagnosis: chronic prostatitis NIH type II (n = 38, chronic epididymitis (n = 12, and chronic urethritis (n = 21. RESULTS: The bacteriological analysis revealed 9 different types of microorganisms, considered to be the etiological agents, isolated in different secretions, including: urine, expressed prostatic secretions, semen and urethral smears: E. Coli (n = 20, Klebsiella (n = 2, Proteus spp. (n = 1, Enterococcus (n = 20, Staphylococcus spp. (n = 1, M. tuberculosis (n = 2, N. gonorrhea (n = 8, Chlamydia tr. (n = 16 and, Ureaplasma urealyticum (n = 1. The infection group had significantly (p < 0.05 lower: semen volume, alpha-glucosidase, fructose, and zinc in seminal plasma and, higher pH than the control group. None of these parameters was sufficiently accurate in the ROC analysis to discriminate between infected and non-infected men. CONCLUSION: Proven bacterial infections of the MRT impact negatively on all the accessory gland function parameters evaluated in semen, suggesting impairment of the secretory capacity of the epididymis, seminal vesicles and prostate. These findings were associated with an infectious related significant increase of semen pH. None of the semen parameters evaluated can be suggested as a diagnostic tool for infection.

    Otitis media is one of the most common childhood diseases worldwide, but because of lack of doctors and health personnel in developing countries it is often misdiagnosed or not diagnosed at all. This may lead to serious, and life-threatening complications. There is, thus a need for an automated computer based image-analyzing system that could assist in making accurate otitis media diagnoses anywhere. A method for automated diagnosis of otitis media is proposed. The method uses image-processing techniques to classify otitis media. The system is trained using high quality pre-assessed images of tympanic membranes, captured by digital video-otoscopes, and classifies undiagnosed images into five otitis media categories based on predefined signs. Several verification tests analyzed the classification capability of the method. An accuracy of 80.6% was achieved for images taken with commercial video-otoscopes, while an accuracy of 78.7% was achieved for images captured on-site with a low cost custom-made video-otoscope. The high accuracy of the proposed otitis media classification system compares well with the classification accuracy of general practitioners and pediatricians (~64% to 80%) using traditional otoscopes, and therefore holds promise for the future in making automated diagnosis of otitis media in medically underserved populations.

    This study was conducted to determine the frequency of otitis media in preterm neonates using otoendoscopy and tympanometry. Prospective study. Wayne State University, Hutzel Women's Hospital Neonatal Intensive Care Unit. Eighty-six preterm infants were included (gestational age otitis media. Kappa statistic and logistic regression were used for statistical analysis. Otoendoscopy was performed in 85 patients. The frequency of otoendoscopy-diagnosed otitis media was 72.9% (62/85). Tympanometry could be performed on 69.76% of the ears. There was 73.5% agreement between the findings of tympanometry and those of otoendoscopy. The association between the presence of otitis media and gestational age at birth was statistically significant. The lower the gestational age, the higher the frequency of otoendoscopy-diagnosed otitis media (P = .001). Otoendoscopically diagnosed otitis media is frequent in preterm neonates. There was agreement between the results of tympanometry and those of otoendoscopy. The frequency of otitis media increased with lower gestational age. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    Acute otitis media is the most common bacterial disease in children under five years; therefore, is one of the most common causes of pediatric consultation. Our objective was to determine the feasibility to consider this disease as a sentinel factor of medical attention. All the new cases of acute otitis media registered between 2008 and 2011 were collected and analyzed. Proportions, ratios, and incidence rates were determined. Also, the limits for proportions were calculated using mid P exact test. In children under five years, we observed 20 % of the cases of non-suppurative otitis media, and suppurative otitis media in 17 %. The reason for acute respiratory infection in relation to cases of otitis media in children of this age increased from 87:1 in 2008 to 53:1 in 2011. The reason of suppurative otitis media decreased in children under five years, even in 2009, when it was registered the highest number of new cases of acute respiratory infection. It was not feasible to determine if acute otitis media is a sentinel indicator; however, we could monitor medical attention indirectly.

  13. Mcph1-deficient mice reveal a role for MCPH1 in otitis media.

    Directory of Open Access Journals (Sweden)

    Jing Chen

    Full Text Available Otitis media is a common reason for hearing loss, especially in children. Otitis media is a multifactorial disease and environmental factors, anatomic dysmorphology and genetic predisposition can all contribute to its pathogenesis. However, the reasons for the variable susceptibility to otitis media are elusive. MCPH1 mutations cause primary microcephaly in humans. So far, no hearing impairment has been reported either in the MCPH1 patients or mouse models with Mcph1 deficiency. In this study, Mcph1-deficient (Mcph1(tm1a (/tm1a mice were produced using embryonic stem cells with a targeted mutation by the Sanger Institute's Mouse Genetics Project. Auditory brainstem response measurements revealed that Mcph1(tm1a (/tm1a mice had mild to moderate hearing impairment with around 70% penetrance. We found otitis media with effusion in the hearing-impaired Mcph1(tm1a (/tm1a mice by anatomic and histological examinations. Expression of Mcph1 in the epithelial cells of middle ear cavities supported its involvement in the development of otitis media. Other defects of Mcph1(tm1a (/tm1a mice included small skull sizes, increased micronuclei in red blood cells, increased B cells and ocular abnormalities. These findings not only recapitulated the defects found in other Mcph1-deficient mice or MCPH1 patients, but also revealed an unexpected phenotype, otitis media with hearing impairment, which suggests Mcph1 is a new gene underlying genetic predisposition to otitis media.

    2015-03-01

    A comparative anatomical study was carried out on the secretory structures of leaflets from taxa belonging to the genus Rhynchosia - taxa difficult to delimit because of uncertain interspecific relations - in order to evaluate the potential diagnostic value of these anatomical traits for taxonomic assignment. A further objective was to establish consensual denomination for these secretory structures. The new anatomical features found in these taxa were sufficiently consistent to separate the species evaluated. The presence and localization of glandular-punctate structures bulbous-based trichomes, the number of layers in the palisade parenchyma and the arrangement of vascular units distinguish the taxa investigated and these characteristics can be extended to other species of Papilionoideae. The trichomes analyzed were described and classified into five types. Depicted in diagrams, photomicrographs, and by scanning electron microscopy, and listed for the first time at the genus and species levels. The information obtained served to effectively distinguish the taxa investigated among species of Papilonoideae.

    2017-01-01

    Topology of membrane proteins provides important information for the understanding of protein function and intermolecular associations. Integrate membrane proteins are generally transported from endoplasmic reticulum (ER) to Golgi and downstream compartments in the plant secretory pathway. Here, we describe a simple method to study membrane protein topology along the plant secretory pathway by transiently coexpressing a fluorescent protein (XFP)-tagged membrane protein and an ER export inhibitor protein, ARF1 (T31N), in tobacco BY-2 protoplast. By fractionation, microsome isolation, and trypsin digestion, membrane protein topology could be easily detected by either direct confocal microscopy imaging or western-blot analysis using specific XFP antibodies. A similar strategy in determining membrane protein topology could be widely adopted and applied to protein analysis in a broad range of eukaryotic systems, including yeast cells and mammalian cells.

    1997-01-01

    The mutant beige mouse (C57BL/6 bg) has a disease characterised by abnormally enlarged cytoplasmic granules in a variety of cells. With the purpose of establishing a suitable cellular model for studying renin secretion, the present study was undertaken to compare renin granule morphology in beige...... (average granular volume 0.681 microm3), whereas 1-2 large granules were present per cell in beige mice. The volume of afferent arteriole that contained secretory granules was lower in the beige mice. We conclude that the beige mouse synthesizes, stores and releases active renin. Renin secretory granules...... in beige mice are grossly enlarged with 1-2 granules per juxtaglomerular cell. Compared with control mice, a similar amount of total renin granule volume per afferent arteriole is contained in a smaller part of beige mouse afferent arteriole. Granular cells from beige mice could therefore be a valuable...

    Cytological examination is crucial for the diagnosis and classification of canine otitis externa. Staining should reveal micro-organisms as perpetuating factors of otitis externa. The aim of the study was to compare four different staining methods (Diff-Quik®, Diff-Quik® after dipping in acetone, Gram Quick stain® and a commercial rapid stain for otitis externa) for ear cytology of dogs with otitis externa and to investigate the agreement of cytology and culture. In a study evaluating dogs with otitis externa, five ear swabs (one for culture and four for cytology) were taken from the horizontal part of the external auditory canal of 224 affected ears and compared semi-quantitatively. Diff-Quik® with and without prior dipping in acetone as well as the Gram Quick stain® displayed a high degree of agreement in the detection of micro-organisms (cocci p = 0.2366; rods p = 0.4832; yeasts p = 0.1574), while the commercial otitis rapid stain revealed significantly less micro-organisms (p stains corresponded to the culture results by >  70%; the agreement was lower with the commercial otitis rapid stain. The quickest and easiest method was staining with Diff-Quik®. Diff-Quik® with or without prior dipping in acetone and the Gram Quick stain® had a high agreement in the detection of microorganisms and can thus be considered nearly equivalent for the diagnosis of otitis externa infectiosa. The commercial otitis rapid stain is less reliable. Based on this study Diff-Quik® can be recommended for the routine cytology of ear swabs. Additionally, a culture may be indicated and must be interpreted in the context of the cytology.

  18. Isolation of intact sub-dermal secretory cavities from Eucalyptus

    2010-09-01

    Full Text Available Abstract Background The biosynthesis of plant natural products in sub-dermal secretory cavities is poorly understood at the molecular level, largely due to the difficulty of physically isolating these structures for study. Our aim was to develop a protocol for isolating live and intact sub-dermal secretory cavities, and to do this, we used leaves from three species of Eucalyptus with cavities that are relatively large and rich in essential oils. Results Leaves were digested using a variety of commercially available enzymes. A pectinase from Aspergillus niger was found to allow isolation of intact cavities after a relatively short incubation (12 h, with no visible artifacts from digestion and no loss of cellular integrity or cavity contents. Several measurements indicated the potential of the isolated cavities for further functional studies. First, the cavities were found to consume oxygen at a rate that is comparable to that estimated from leaf respiratory rates. Second, mRNA was extracted from cavities, and it was used to amplify a cDNA fragment with high similarity to that of a monoterpene synthase. Third, the contents of the cavity lumen were extracted, showing an unexpectedly low abundance of volatile essential oils and a sizeable amount of non-volatile material, which is contrary to the widely accepted role of secretory cavities as predominantly essential oil repositories. Conclusions The protocol described herein is likely to be adaptable to a range of Eucalyptus species with sub-dermal secretory cavities, and should find wide application in studies of the developmental and functional biology of these structures, and the biosynthesis of the plant natural products they contain.

    Acute leukemia is a well known childhood cancer. The relation between leukemia and otological symptoms has long been established but is highly rare as a debut symptom of leukemia. External otitis is a common condition affecting many children, and most cases are successively treated with topical medicine. Here we present a child with acute external otitis later shown to be the debut symptom of acute myeloid leukemia, to our knowledge the first specific case described. We have reviewed the literature to find red flags for suspicion of severe disease in case of acute external otitis. Copyright © 2018 Elsevier B.V. All rights reserved.

    2017-09-01

    Haemophilus parainfluenzae is a nutritionally fastidious, Gram-negative bacterium with an oropharyngeal/nasopharyngeal carriage niche that is associated with a range of opportunistic infections, including infectious endocarditis and otitis media (OM). These infections are often chronic/recurrent in nature and typically involve bacterial persistence within biofilm communities that are highly resistant to host clearance. This study addresses the primary hypothesis that H. parainfluenzae forms biofilm communities that are important determinants of persistence in vivo The results from in vitro biofilm studies confirmed that H. parainfluenzae formed biofilm communities within which the polymeric matrix was mainly composed of extracellular DNA and proteins. Using a chinchilla OM infection model, we demonstrated that H. parainfluenzae formed surface-associated biofilm communities containing bacterial and host components that included neutrophil extracellular trap (NET) structures and that the bacteria mainly persisted in these biofilm communities. We also used this model to examine the possible interaction between H. parainfluenzae and its close relative Haemophilus influenzae , which is also commonly carried within the same host environments and can cause OM. The results showed that coinfection with H. influenzae promoted clearance of H. parainfluenzae from biofilm communities during OM infection. The underlying mechanisms for bacterial persistence and biofilm formation by H. parainfluenzae and knowledge about the survival defects of H. parainfluenzae during coinfection with H. influenzae are topics for future work.

    We assess the utility of CT in the diagnosis of the sped of and complications associated with cholesteatomas of middle ear. We review retrospectively the CT studies of 116 patients who underwent surgical treatment after a preoperative diagnosis of cholesteatoma between 1988 and 1992. We compare the findings at CT and surgery, taking into account the site, extension, complications and noteworthly surgical aspects. In our study, CT disclosed the presence of a mass within the tympanic cavity in all cases (100%). Among the entire study population, there were 103 cases of cholesteatoma and 13 of chronic otitis media (COM). CT revealed signs compatible with cholesteatoma in 99 cases, 3 of which were classified as COM and 14 in which it was impossible to distinguish between COM and cholesteatoma. CT discolsed a high correlation coefficient for the detection of erosion of the ossicular chain (sensitivity, 94.4%; specificity, 63.6%) and a moderate coefficient for fistula in lateral semicircular canal (75.0% and 97.0%), rupture of the tegmen tympani (76.9% and 96.1%) and dehiscence of the osseous portion of the facial nerve canal (66.6% and 95.6%). In our experience, wich coincides with reports in the literature, we conclude that CT is currebtly an excellent imaging method for the presurgical assessment of cholesteatoma. Additional explorations are usually unneccessary. 12 refs

  3. The link between otitis media with effusion and allergy: a potential role for intranasal corticosteroids.

    Lack, Gideon; Caulfield, Helen; Penagos, Martin

    2011-05-01

    We reviewed the evidence linking otitis media with effusion (OME) and atopy, with the goal of clarifying the possible role of intranasal corticosteroids (INSs) in OME treatment. In August 2009, the MEDLINE database was searched for primary studies on OME epidemiology, pathophysiology, and treatment. Relevant clinical guidelines were obtained. Interpreting OME research is complicated by variable disease definitions, patient populations, methodologies, and outcomes assessments, along with the possibility of spontaneous resolution. However, evidence links OME with atopic conditions including allergic rhinitis; observed prevalence of allergic rhinitis in patients with chronic or recurrent OME ranges from 24% to 89%. Such findings have prompted evaluations of common allergy medications for OME treatment. While short-term use of INSs alone or combined with antibiotics has shown benefit in some studies, more prolonged treatment protocols and long-term clinical outcomes will require critical assessment. Evidence suggesting epidemiologic and pathophysiologic links between allergy and OME has prompted investigation into a potential role for INSs in OME management, with promising initial results. Benefits of considering medical treatment in patients with OME prior to surgery include both the potential reductions in allergic inflammation and the naturally occurring spontaneous resolution of OME in these patients. © 2011 John Wiley & Sons A/S.

    Full Text Available Diseases of the ENT organs are among the commonly prevalent and dangerous pathologies of childhood, occurring as a complication of respiratory, bacterial diseases and HIV infection. One of the serious complications of HIV infection in children is the lesion of ENT organs. In HIV infected children, in addition to suppurative diseases occur middle ear diseases with nonsuppurative origin. A total of 79 HIV infected children aged 3-14 years with different pathologies of the nasal cavity, nasopharynx and paranasal sinuses were included into the current study. The control group included 20 healthy children of comparable age and sex. The survey was conducted in the ENT department of the Children’s Multi-Medical Center, in Bukhara region. Children with a diagnosis of suppurative otitis media and/or history of suppurative otitis media were not included into the study. All HIV infected children, along with physical examination, were performed ENT examination, finger study, X-ray examination of the paranasal sinuses, audiological research and impedancemetry.

    Otitis media (OM) is the leading cause of acute physician visits and prescription of antibiotics for children. Current standard techniques to diagnose acute otitis media (AOM) are limited by their ability to probe only changes in symptoms of the bacterial infection that cause AOM. Furthermore, they are not able to detect the presence of or identify bacteria causing AOM, which is important for diagnosis and proper antibiotic treatment. Our goal is to detect the presence of and identify the pathogens involved in causing AOM based on their biochemical profile using Raman spectroscopy (RS). An inVia confocal Raman microscope (Renishaw) at 785 nm was used to detect bacteria causing AOM in vitro. The three main bacteria that cause AOM, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae were cultured in chocolate agar and Mueller-Hinton agar to determine which agar type would minimize Raman signal from the growth agar. Preliminary results identified specific Raman spectral features characteristic of S. pneumoniae. RS has the potential to accurately diagnose AOM, which will help in identifying the antibiotic that will be most beneficial for the patient and ultimately decrease the course of infection.

    Full Text Available Anouk Speets1, Judith Wolleswinkel1, Cristina Cardoso21Pallas health research and consultancy, Rotterdam, the Netherlands; 2GlaxoSmithKline, Algés, PortugalAbstract: This study aimed to estimate the resource consumption and societal impact of otitis media (OM in children younger than five years of age in Portugal. An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.Keywords: otitis media, costs, societal burden, Portugal

    To determine the prevalence of otitis media with effusion (OME) in children with Down syndrome (DS), and the associated to hearing loss at the age of 8 years. A national population based clinical study of all children with DS born in Norway in 2002. OME was found in 20 out of 52 (38%) children. Those with OME had a significant lower hearing level with a mean pure tone average (PTA) of 33.4 dB HL compared to children with no OME whose mean PTA was 21.7 dB HL (p children with DS as current otitis media was found in one of three. This reduced hearing ability in children with DS due to OME at age of 8 strongly emphasizes the need for optimal treatment and follow up to optimize hearing rehabilitation. The findings are further supported by the population based study design, the focus on the narrow age band and the high response rate. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Bactericidal/permeability-increasing protein (BPI) fold-containing family B, member 3 (BPIFB3) is an endoplasmic reticulum (ER)-localized host factor that negatively regulates coxsackievirus B (CVB) replication through its control of the autophagic pathway. Here, we show that another member of the BPIFB family, BPIFB6, functions as a positive regulator of CVB, and other enterovirus, replication by controlling secretory pathway trafficking and Golgi complex morphology. We show that similar to BPIFB3, BPIFB6 localizes exclusively to the ER, where it associates with other members of the BPIFB family. However, in contrast to our findings that RNA interference (RNAi)-mediated silencing of BPIFB3 greatly enhances CVB replication, we show that silencing of BPIFB6 expression dramatically suppresses enterovirus replication in a pan-viral manner. Mechanistically, we show that loss of BPIFB6 expression induces pronounced alterations in retrograde and anterograde trafficking, which correlate with dramatic fragmentation of the Golgi complex. Taken together, these data implicate BPIFB6 as a key regulator of secretory pathway trafficking and viral replication and suggest that members of the BPIFB family participate in diverse host cell functions to regulate virus infections. Enterovirus infections are associated with a number of severe pathologies, such as aseptic meningitis, dilated cardiomyopathy, type I diabetes, paralysis, and even death. These viruses, which include coxsackievirus B (CVB), poliovirus (PV), and enterovirus 71 (EV71), co-opt the host cell secretory pathway, which controls the transport of proteins from the endoplasmic reticulum to the Golgi complex, to facilitate their replication. Here we report on the identification of a novel regulator of the secretory pathway, bactericidal/permeability-increasing protein (BPI) fold-containing family B, member 6 (BPIFB6), whose expression is required for enterovirus replication.

    Chronic lymphocytic leukemia (CLL) cells can secrete immunoglobulin M. However, it is not clear whether secretory IgM (sIgM) plays a role in disease progression. We crossed the Eμ-TCL1 mouse model of CLL, in which the expression of human TCL1 oncogene was driven by the V(H) promoter-Ig(H)-Eμ enhancer, with MD4 mice whose B cells produced B-cell receptor (membrane-bound IgM) and sIgM with specificity for hen egg lysozyme (HEL). CLL cells that developed in these MD4/Eμ-TCL1 mice reactivated a parental Ig gene allele and secreted IgM, and did not recognize HEL. The MD4/Eμ-TCL1 mice had reduced survival, increased myeloid-derived suppressor cells (MDSC), and decreased numbers of T cells. We tested whether sIgM could contribute to the accumulation of MDSCs by crossing μS -/- mice, which could not produce sIgM, with Eμ-TCL1 mice. The μS -/- /Eμ-TCL1 mice survived longer than Eμ-TCL1 mice and developed decreased numbers of MDSCs which were less able to suppress proliferation of T cells. We targeted the synthesis of sIgM by deleting the function of XBP-1s and showed that targeting XBP-1s genetically or pharmacologically could lead to decreased sIgM, accompanied by decreased numbers and reduced functions of MDSCs in MD4/Eμ-TCL1 mice. Additionally, MDSCs from μS -/- mice grafted with Lewis lung carcinoma were inefficient suppressors of T cells, resulting in slower tumor growth. These results demonstrate that sIgM produced by B cells can upregulate the functions of MDSCs in tumor-bearing mice to aggravate cancer progression. In a mouse model of CLL, production of secretory IgM led to more MDSCs, fewer T cells, and shorter survival times for the mice. Thus, secretory IgM may aggravate the progression of this cancer.

    2012-01-01

    Full Text Available Introduction- Serous Ottis media or otitis media with effusion is a common cause of hearing loss of acute onset. The common presentation will be a block or reduced hearing possible after a travel or flight. Most of the cases present with conductive hearing loss while some may present with mixed or even pure sensory hearing loss. Background- we study hundred patients diagnosed with serous otitis media for the type of hearing loss and characterize the management strategy. Conclusion- Serous otitis media is a common cause of hearing loss which is mostly conductive and is amenable to treatment while some rare cases which may persist may require assistive hearing with amplification. Although sensorineral hearing loss is rare in otitis media, it is seen in practice along with mixed hearing loss. The pathophysiology of the neural affection of hearing loss remains a mystery although many theories exist.

    acute otitis media is a frequent disease in the pediatric age. About 2 % of all cases develop intracranial complications such as meningitis. The cerebral infarction originates meningitis and usually occurs in the venous system. The presence of a cerebral artery infarction secondary to acute otitis media is a rare cause described in the literature. a girl of 12 months who presented a febrile syndrome due to acute otitis media and mental confusion. On physical examination, she appeared sleepy with anisocoria, mydriasis in the right eye and left hemiparesis. The computed tomography examination showed extensive cerebral artery infarction. The patient's parents refused the proposed surgical treatment and the girl died 48 hours later. regardless of the current technological advances, the clinical prognosis of cerebral infarction associated with acute otitis media is bad. The focused neurological signs and progressive clinical deterioration should raise suspicion that antimicrobial therapy is not effective.

    This case-control study investigated the possible association between home environmental air pollutants and their effect on otitis media and asthma in children. Patients with physician-diagnosed otitis (n = 125, 74% response), with asthma (n = 137, 80% response), and controls (n = 237, 72% response) from a private pediatric practice seen between October 1986 and May 1987 were studied. A questionnaire inquired about housing characteristics (i.e., age, insulation, heating system) and sources of indoor air pollution such as cigarette smoking, use of woodburning stoves, household pets, etc. Analysis of the responses confirmed previous findings of significant relationships between maternal smoking (P = .021), and the presence of pets (P = .034) and the occurrence of asthma. A newly reported relationship between exposure to woodburning stoves and the occurrence of otitis (P less than .05) was reported. This implicates yet another risk factor (wood burning) in the etiology of otitis media.

    To investigate the relation between otitis media in the language acquisition years and the occurrence of delayed reading between the ages of 7 and 10. Participants were 40 children, half of whom had a history of otitis media between the ages of birth and three years and half who were free of the disease. These children, now ages 7-10, were tested with the Stanford Beint and Arabic Dyslexia Assessment Test. Children with a history of otitis media scored over a year below grade level in reading and significantly below controls on Arabic Dyslexia Assessment tests as well as on the Verbal IQ factor on the Stanford Binet. Children with early onset otitis media (birth to three years) tend to be at greater risk for delayed reading than age-matched controls. Published by Elsevier Ireland Ltd.

    Full Text Available BACKGROUND: Bacteria persist within biofilms on the middle ear mucosa of children with recurrent and chronic otitis media however the mechanisms by which these develop remain to be elucidated. Biopsies can be difficult to obtain from children and their small size limits analysis. METHODS: In this study we aimed to investigate biofilm presence in middle ear effusion (MEE from children with recurrent acute otitis media (rAOM and to determine if these may represent infectious reservoirs similarly to those on the mucosa. We examined this through culture, viability staining and fluorescent in situ hybridisation (FISH to determine bacterial species present. Most MEEs had live bacteria present using viability staining (32/36 and all effusions had bacteria present using the universal FISH probe (26/26. Of these, 70% contained 2 or more otopathogenic species. Extensive DNA stranding was also present. This DNA was largely host derived, representing neutrophil extracellular traps (NETs within which live bacteria in biofilm formations were present. When treated with the recombinant human deoxyribonuclease 1, Dornase alfa, these strands were observed to fragment. CONCLUSIONS: Bacterial biofilms, composed of multiple live otopathogenic species can be demonstrated in the MEEs of children with rAOM and that these contain extensive DNA stranding from NETs. The NETs contribute to the viscosity of the effusion, potentially contributing to its failure to clear as well as biofilm development. Our data indicates that Dornase alfa can fragment these strands and may play a role in future chronic OM treatment.

    To evaluate the effects of oral steroids alone or followed by intranasal steroids versus watchful waiting on the resolution of otitis media with effusion in children aged 2-11 years. A total of 290 children with bilateral otitis media with effusion were assigned to 3 groups: group A was treated with oral steroids followed by intranasal steroids, group B was treated with oral steroids alone and group C was managed with watchful waiting. Patients were evaluated with audiometry and tympanometry. The complete resolution rates of otitis media with effusion were higher in groups A and B than in group C at six weeks. There were no significant differences in otitis media with effusion resolution rates between the groups at three, six and nine months. Oral steroids lead only to a quick resolution of otitis media with effusion, with no long-term benefits. There was no benefit of using intranasal steroids in the management of otitis media with effusion.

    To compare measurements of body temperature obtained with auricular thermometers versus rectal thermometers in dogs with otitis externa. Prospective study. 100 client-owned dogs: 50 with and 50 without clinical evidence of otitis externa. Dogs were evaluated for the presence of otitis externa on the basis of clinical signs, otoscopic examination, and cytologic evaluation of ear exudate. Auricular and rectal temperatures were obtained simultaneously in all dogs prior to and following ear examination. There was a high correlation between auricular and rectal temperatures in dogs with otitis externa both prior to and after ear manipulation. Significant differences were not detected in temperature measurements among dogs with different degrees of otitis externa. Auricular temperature readings obtained by use of an auricular thermometer in dogs with otitis externa are accurate measurements of body temperature, compared with rectal temperature measurements. Temperature measurements are reliable before and after examination of the ear canal.

    Determine the incidence of ear infections in cochlear implant patients, evaluate the contribution of otitis media to complications, describe the bacteriology of otitis media in the cochlear implant population, the treatment provided at our center, and the long term outcome. Data collected included age at implantation, history of otitis media or ear tubes, etiology of hearing loss, inner ear anatomy, postoperative infections, time to infection, route of antibiotic administration, and interventions for infections. Categories of infection were acute otitis media, otitis media with effusion, tube otorrhea, meningitis, scalp cellulitis, and infection at the implant site. Middle ear infections were diagnosed in 37% of implanted ears. Extension of middle ear infections into the implant site occurred in 2.8% of all implants (n = 16). Of the 16 infected devices, 10 were successfully treated with antibiotic therapy and did not require explantation. The retained implant group and explanted group both included some middle ear microbes such as Haemophilus influenzae and Streptococcus pneumoniae, as well as skin flora such as Staphylococcus aureus. Otitis media in pediatric cochlear implant patients is a common event and usually does not lead to complications of the cochlear implant. However, when the ear infection spreads to the scalp and the implant site, it is still possible to eliminate the infection using antibiotic therapy, particularly when treatment is directed to the specific organism that is recovered from the infected space and the duration and route of antibiotic treatment is carefully considered.

    2014-06-01

    To examine the association between hospitalisations for otitis media and area-level measures of household crowding among children in New Zealand. Counts of hospital admissions for otitis media by census area unit were offset against population data from the 2006 national census. Area-level household crowding, exposure to tobacco smoke in the home, equivalised income and individual-level characteristics age and sex were adjusted for. To examine effect modification by ethnicity, three separate poisson models were examined for the total, Māori and non-Māori populations. Household crowding was significantly associated with hospital admissions for otitis media after adjustment in all three models. Neighbourhoods with the highest compared to the lowest proportion of crowded homes exhibited incidence rate ratios of 1.25 (95%CI 1.12-1.37) in the total population, 1.59 (95%CI 1.21-2.04) in the Māori restricted model and 1.17 (95%CI 1.06-1.32) in the non-Māori restricted model. Otitis media hospitalisations are associated with area-level measures of household crowding and other risk factors in this ecological study. The largest increase in otitis media incidence relative to neighbourhood rates of household crowding was exhibited among Māori cases of otitis media. This study adds weight to the growing body of literature linking infectious disease risk to overcrowding in the home. © 2014 The Authors. ANZJPH © 2014 Public Health Association of Australia.

    Full Text Available Otitis externa is no longer viewed as an isolated disease of the ear canal, but is a syndrome that is often a reflection of underlying dermatological disease. Causes are classified as predisposing (increase the risk of otitis ; primary (directly induce otitis, secondary (contribute to otitis only in an abnormal ear or in conjunction with predisposing factors and perpetuating (result from inflammation and pathology in ear, prevent resolution of otitis. Common primary causes include foreign bodies, hypersensitivity (particularly atopy and food allergy, keratinisation disorders (most commonly primary idiopathic seborrhoea and hypothyroidism and earmites, particularly in cats. A systematic diagnostic procedure is required to identify causes and contributing factors. This should include history, clinical examination, otoscopy and cytology in all cases and culture and sensitivity as well as otitis media assessment and biopsy in severe and recurrent cases. Ancillary tests may be required depending on the underlying cause. Treatment consists of identifying and addressing predisposing and primary factors ; cleaning the ear canal ; topical therapy ; systemic therapy where necessary ; client education ; follow-up ; and preventive and maintenance therapy as required.

    In veterinary medicine, Staphylococcus schleiferi was previously assumed to be an inhabitant of carnivore skin, however, more recently, it has been repeatedly documented in the literature as both an inhabitant and as a pathogen. In order to determine the frequency of nasal carriage, and the methicillin susceptibility pattern of S. schleiferi from healthy dogs as well as dogs with otitis and/or pyoderma, a prospective study including 24 dogs with healthy ears and skin, 27 dogs with healthy ears and pyoderma, 15 dogs with otitis without pyoderma and 20 dogs with both otitis and pyoderma was performed. Specimens were obtained and cultured and isolates were identified as S. schleiferi based on growth and biochemical characteristics. S. schleiferi was isolated from the nares of 1 healthy dog, 3 dogs with recurrent pyoderma, 2 dogs with recurrent otitis, and 1 dog with both recurrent otitis and pyoderma. One of the S. schleiferi isolates was methicillin resistant. Nasal carriage of S. schleiferi does occur in healthy dogs as well as dogs with otitis and pyoderma. Methicillin resistant and sensitive S. schleiferi can be found in the nares of dogs with diseased ears and skin. Copyright © 2012 Elsevier B.V. All rights reserved.

    Chronic pancreatitis is an ongoing inflammatory process that may over time lead to mal digestion, malabsorption and diabetic syndrome. Identification of risk (etiological) factors based on classifications TIGAR-O or later M-ANNHEIM. These factors (environmental and / or genetic) leads to failure of the stability of the digestive and lysosomal enzymes in the acinar cells, resulting in premature activation of digestive enzymes in the pancreas, and repeated nekroinflamation and fibrosis. The incidence has of the upward trend. Clinically the disease manifests itself in most cases with pain and possibly with nonspecific dyspeptic troubles. Decisive role in the diagnosis playing imaging methods, trans abdominal ultrasonography, computed tomography, magnetic resonance imaging, magnetic cholangiopancretography and foremost endoscopic ultrasonography, which has the highest sensitivity and specificity. Endoscopic retrograde cholangiopancreatography is currently regarded as a method for therapy, not for diagnosis. Less importance is now attached to a functional test. Symptomatic treatment is usually conservative. Abstinence is necessary, easily digestible, but calorie-rich diet with reduced fat. Most patients needed treatment with analgesics. In case of insufficient effect of analgesics is necessary to consider endoscopic therapy or surgery. If the external secretory insufficiency is present are served pancreatic extracts. Diabetic syndrome requires insulin delivery. Generally, chronic pancreatitis is a disease treatable but incurable. Proportion of patients are also dying of pancreatic cancer. (author)

    Amelogenins are the most abundant protein species in forming dental enamel, taken to regulate crystal shape and crystal growth. Unprotonated amelogenins can bind protons, suggesting that amelogenins could regulate the pH in enamel in situ. We hypothesized that without amelogenins the enamel would acidify unless ameloblasts were buffered by alternative ways. To investigate this, we measured the mineral and chloride content in incisor enamel of amelogenin-knockout (AmelX(-/-)) mice and determined the pH of enamel by staining with methyl-red. Ameloblasts were immunostained for anion exchanger-2 (Ae2), a transmembrane pH regulator sensitive for acid that secretes bicarbonate in exchange for chloride. The enamel of AmelX(-/-) mice was 10-fold thinner, mineralized in the secretory stage 1.8-fold more than wild-type enamel and containing less chloride (suggesting more bicarbonate secretion). Enamel of AmelX(-/-) mice stained with methyl-red contained no acidic bands in the maturation stage as seen in wild-type enamel. Secretory ameloblasts of AmelX(-/-) mice, but not wild-type mice, were immunopositive for Ae2, and stained more intensely in the maturation stage compared with wild-type mice. Exposure of AmelX(-/-) mice to fluoride enhanced the mineral content in the secretory stage, lowered chloride, and intensified Ae2 immunostaining in the enamel organ in comparison with non-fluorotic mutant teeth. The results suggest that unprotonated amelogenins may regulate the pH of forming enamel in situ. Without amelogenins, Ae2 could compensate for the pH drop associated with crystal formation. © International & American Associations for Dental Research 2014.

    2011-01-01

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    INTRODUCTION: Otitis media (OM) is a common disease in childhood and hearing loss (HL) is the most common complication. Prolonged HL may lead to language delay and cognitive difficulties. However, the consequences of HL due to OM are not fully understood. The aim of this study was to determine...... proportional odds regression. RESULTS: Out of 94,745 successful pregnancies, 35,946 children without malformations and their parents completed a questionnaire at age 11 years. No associations were observed between number of OM episodes and school performance, even in children with ≥7 OM episodes. CONCLUSION......: This national birth-cohort study did not support the hypothesis that the number of OM episodes in childhood is associated with reduced self-reported school performance in children at 11 years of age....

    %.

    La otitis media y el colesteatoma son un serio problema en América Latina, debido a factores de malnutrición, pobreza, falta de atención médica, contaminación de las aguas y polución ambiental. Un alto porcentaje de estos pacientes requieren tratamiento quirúrgico.

    La cirugía del colesteatoma debe orientarse en forma radical, eliminando totalmente la patología para evitar la recurrencia y ojalá practicarla en un solo tiempo quirúrgico.

    The 2004 American Academy of Pediatrics acute otitis media guidelines urge parents to weigh the benefits of reduced antibiotic use, adverse drug events, and future resistance versus risks of extra costs and sick days resulting from guideline use. The value of decreased antibiotic resistance has not been quantified. The objective was to perform cost-utility analysis, estimating the resistance value of implementing the guidelines for acute otitis media treatment for children life-day units. The minimum resistance benefit value, where the benefits of the American Academy of Pediatrics guidelines would at least balance their costs, was defined as the guidelines' incremental costs minus their other benefits. For a child 2 to benefit at 0.77 quality-adjusted life-days per antibiotic prescription avoided for the guidelines' benefits to balance their costs. For the 6- to life-days per prescription avoided. Results were sensitive to the dollar cost utility; when willingness to pay ranged from $20,000 to $200,000 per quality-adjusted life-year, results ranged from 0.36 and 0.30 quality-adjusted life-days up to 4.10 and 3.57 quality-adjusted life-days for the 2- to work days. From a societal perspective, trading 0.30 to 4 quality-adjusted life-days to avoid 1 antibiotic course might be desirable; from a parental perspective, this may not be as desirable. Parent demand for antibiotics may be rational when driven by the value of parent time. Other approaches that have the potential to reduce antibiotic use, such as wider use of influenza vaccine and improved rapid viral diagnostic techniques, might be more successful.

    Objectives (1) Describe longitudinal trends in annual prevalence of hospital admission for pediatric acute otitis media (AOM) and complications of AOM (CAOM) since introduction of pneumococcal vaccination in 2000 and (2) describe the longitudinal trend of prevalence of hospital admission for pneumococcal meningitis in children with AOM-related diagnoses in the postvaccination era. Study Design Retrospective analysis of Kids' Inpatient Database from 2000 to 2012. Setting Community, nonrehabilitation hospitals. Subjects and Methods To determine annual prevalence of admission for AOM/CAOM, nationally weighted frequencies of children aged otitis media, acute mastoiditis, suppurative labyrinthitis, and/or acute petrositis were collected. The frequency of coexisting pneumococcal meningitis diagnoses among these patients was also collected. Trend analysis of prevalences of admission for AOM/CAOM and for pneumococcal meningitis occurring in the setting of AOM/CAOM from 2000 to 2012 was performed. Results Between 2000 and 2012, annual prevalence of admission for AOM/CAOM decreased from 3.956 to 2.618 per 100,000 persons ( P < .0001) (relative risk reduction 34%). Declines in admission prevalence were most pronounced in children <1 year of age (from 22.647 to 8.715 per 100,000 persons between 2000 and 2012, P < .0001) and 1 to 2 years of age (from 13.652 to 5.554 per 100,000 persons between 2000 and 2012, P < .0001). For all ages, the admission prevalence for pneumococcal meningitis and concomitant AOM/CAOM decreased (from 1.760 to 0.717 per 1,000,000 persons, P < .0001) over the study period. Conclusions The prevalence of hospital admission for pediatric AOM/CAOM has declined since the advent of pneumococcal vaccination. Admission rates for pneumococcal meningitis with AOM/CAOM have similarly declined.

    It is recommended to perform follow-up tympanometry and if necessary tonal audiometry in children who have normal plain otoscopy findings after recovering from acute otitis media (AOM). Children with Type B tympanogram, 3 months following the onset of AOM, are very likely to have a conductive hearing loss. Type B tympanogram is a much better indicator of effusion in the middle ear compared to plain otoscopy. This study was undertaken to investigate the frequency and duration of middle ear effusion in children following an episode of acute otitis media, to track changes in tonal audiometry and tympanometry findings in the post-AOM period, and recognize the optimal timing for performing both tests. In this study, 125 children aged 5-7 years with bilateral AOM were randomly selected and separately followed up for 3 months. The children underwent six ear, nose, and throat (ENT 1-6) examinations, six tympanometries (TM 1-6), and three tonal audiometries (TA 1-3). Evaluation of nasopharynx was done at the ENT 1 examination. Children who received ventilation tubes were followed for 21 month altogether. At the first otoscopy, pathological findings were recorded in 250 ears/125 children (100.0%). The number of pathological otoscopy findings decreased at each subsequent examination. At ENT 6 all children had normal otoscopy findings. Type B tympanogram was detected in 49/250 (19.6%) ears at TM 6, performed 3 months following the onset of the disease. At the TA 1 conductive hearing impairment was recorded in 158/250 (63.2%) ears, at TA 2 in 66/250 (26.4%), and at TA 3 in 39/250 (15.6%). Most of them were associated with Type B tympanogram.

    Approximately 75% of children with cleft palate (CP) have Otitis Media with Effusion (OME) histories. Evidence for the effective management of OME in these children is lacking. The inconsistency in outcome measurement in previous studies has led to a call for the development of a Core Outcome Set (COS). Despite the increase in the number of published COS, involvement of patients in the COS development process, and methods to integrate the views of patients and health professionals, to date have been limited. A list of outcomes measured in previous research was identified through reviewing the literature. Opinion on the importance of each of these outcomes was then sought from key stakeholders: Ear, Nose and Throat (ENT) surgeons, audiologists, cleft surgeons, speech and language therapists, specialist cleft nurses, psychologists, parents and children. The opinion of health professionals was sought in a three round Delphi survey where participants were asked to score each outcome using a bespoke online system. Parents and children were also asked to score outcomes in a survey and provided an in-depth insight into having OME through semi-structured interviews. The results of the Delphi survey, interviews and parent/patient survey were brought together in a final consensus meeting with representation from all stakeholders. A final set of eleven outcomes reached the definition of "consensus in" to form the recommended COS: hearing; chronic otitis media (COM); OME; receptive language skills; speech development; psycho social development; acute otitis media (AOM); cholesteatoma; side effects of treatment; listening skills; otalgia. We have produced a recommendation about the outcomes that should be measured, as a minimum, in studies of the management of OME in children with CP. The development process included input from key stakeholders and used novel methodology to integrate the opinion of healthcare professionals, parents and children.

    Full Text Available The aim of the research was to access clinical efficacy of oral rehydration therapy using III generation solutions in the treatment of secretory diarrhea in infants. To achieve this aim, on the basis of infectious box unit (enteric infections of regional clinical hospital (Chernivtsi we examined 116 infants, randomly selected, with acute gastroenteritis, who admitted to the hospital with signs of exycosis due to secretory diarrhea. Among examined patients, 73 (67.5 % children with the purpose of oral rehydration therapy received rehydration solutions, and 35 (32.4 % patients received other rehydration solutions. Monitoring of the dynamics of patients’ state enabled to state that, when we used III generation mixture as a main component of oral rehydration therapy, rate of positive dynamics in terms of clinical status of patients was significantly faster, in particular, body temperature, frequency and nature of bowel movements normalized significantly earlier, vomiting disappeared. In children treated with rehydration solutions, compared with patients receiving other rehydration solutions, odds ratio to confine only oral rehydration was 3.7 (95% CI 0.4–38.9 with an absolute risk to avoid the need for infusion therapy — 11 %.

  16. Post-secretory fate of host defence components in mucus.

    Salathe, Matthias; Forteza, Rosanna; Conner, Gregory E

    Airway mucus is a complex mixture of secretory products that provide a multifaceted defence against infection. Among many antimicrobial substances, mucus contains a peroxidase identical to milk lactoperoxidase (LPO) that is produced by goblet cells and submucosal glands. Airway secretions contain the substrates for LPO, namely thiocyanate and hydrogen peroxide, at concentrations sufficient for production of the biocidal compound hypothiocyanite, a fact confirmed by us in vitro. In vivo, inhibition of airway LPO in sheep significantly inhibits bacterial clearance, suggesting that the LPO system is a major contributor to host defences. Since secretory products including LPO are believed to be steadily removed by mucociliary clearance, their amount and availability on the surface is thought to be controlled solely by secretion. In contrast to this paradigm, new data suggest that LPO and other substances are retained at the ciliary border of the airway epithelium by binding to surface-associated hyaluronan, thereby providing an apical, fully active enzyme pool. Thus, hyaluronan, secreted from submucosal gland cells, plays a previously unrecognized pivotal role in mucosal host defence by retaining LPO and possibly other substances important for first line host defence at the apical surface 'ready for use' and protected from ciliary clearance.

    2012-02-01

    Full Text Available Ipomoea asarifolia (Desr. Roem. & Schult., Convolvulaceae, is a weed that infests agricultural areas and is toxic to cattle. In spite of its toxicity, the leaves of this plant are used in traditional remedies in the state of Bahia, Brazil. The present work describes the leaf anatomy of I. asarifolia and characterizes the exudates of its secretory structures. The leaves have a unistratified epidermis composed of ordinary cells with straight to slightly sinuous anticlinal walls and thin cuticles. Paracytic stomata are found on both surfaces of the leaves at the same level as the ordinary epidermal cells. Trichomes producing polysaccharide secretions occur on the petiole and leaf blade and are considered colleters. The mesophyll is dorsiventral and the vascular bundle of the central vein is bicollateral. Two opposed nectaries occur on the petiole near the leaf blade. Each nectary is composed of a small canal with internal ramifications and numerous secretory trichomes. The laticiferous glands are articulated, not anastomosed, and are composed of large diameter cells with thin cell walls. The secretions of the laticiferous glands are lipidic.

  18. Identification of Secretory Odontoblasts Using DMP1-GFP Transgenic Mice

    Terminal differentiation of odontoblasts from dental papilla is a long process involving several intermediate steps and changes in the transcriptional profile and expression of proteins secreted by cells in the odontoblast lineage. Transgenic mouse lines in which GFP expression is under the control of tissue-and stage specific promoters have provided powerful experimental tools for identification and isolation of cells at specific stages of differentiation along a lineage. Our previous studies showed utilization of pOBCol3.6GFP and pOBCol2.3GFP animals for identification of odontoblasts at early and late stages of polarization respectively. In the present study we used the DMP1-GFP transgenic animal as an experimental model to examine its expression during the differentiation of odontoblasts from progenitor cells in vivo and in vitro. Our observations showed that DMP1-GFP transgene is first activated in secretory/functional odontoblasts engaged in secretion of predentin and then transiently expressed at high levels in newly differentiated odontoblasts. Expression of DMP1-GFP was down-regulated in highly differentiated odontoblasts. The temporal and spatial pattern of expression of DMP1-GFP transgene closely mimics the expression of endogenous DMP1. This transgenic animal will facilitate studies of gene expression and biological functions in secretory/functional odontoblasts. PMID:21172466

    Streptococcus pneumoniae is the predominant otitis media pathogen and its prevention through effective vaccination could diminish childhood illness and antibiotic use. This paper reviews 5 pneumococcal conjugate vaccine (PCV) trials that used otitis media as an endpoint: Northern California Kaiser Permanente (NCKP; vaccine, 7-valent PCV [PCV7]-CRM); Finnish Otitis Media (FinOM; vaccines, PCV7-CRM or PCV7-OMPC); Native American Trial (vaccine, PCV7-CRM); Pneumococcal Otitis Efficacy Trial (POET; vaccine, 11-valent PCV [PCV11]-PD). For the microbiological endpoint, vaccine efficacy against vaccine-serotype pneumococcal otitis media was about 60% across trials. Against the clinical endpoint of all episodes, vaccine efficacy was 7% (PCV7-CRM/NCKP), 6% (PCV7-CRM/FinOM), −1% (PCV7-OMPC/FinOM), and −0.4% (PCV7-CRM/Native American Trial); 34% against first episodes of ear, nose, and throat specialist-referral cases (PCV11-PD/POET). Both follow-up through 2 years of age, for the 5 trials, and long-term follow-up, for PCV7-CRM/NCKP and PCV7-CRM/FinOM, demonstrated greater vaccine efficacy against recurrent AOM and tympanostomy-tube placement, suggesting that vaccination against early episodes of AOM may prevent subsequent episodes of complicated otitis media. Although study designs varied by primary endpoint measured, age at follow-up, source of middle-ear fluid for culture, case ascertainment, and type of randomization, each clinical trial demonstrated vaccine efficacy against microbiological and/or clinical otitis media.

    The pneumococcus is a major otitis media (OM) pathogen, but data are conflicting regarding whether otitis-prone children have impaired humoral immunity to pneumococcal antigens. We and others have shown that otitis-prone and healthy children have similar antibody titers to pneumococcal proteins and polysaccharides (vaccine and nonvaccine types); however, the quality of antibodies from otitis-prone children has not been investigated. Antibody function, rather than titer, is considered to be a better correlate of protection from pneumococcal disease. Therefore, we compared the capacities of antibodies from otitis-prone (cases) and healthy (controls) children to neutralize pneumolysin, the pneumococcal toxin currently in development as a vaccine antigen, and to opsonize pneumococcal vaccine and nonvaccine serotypes. A pneumolysin neutralization assay was conducted on cholesterol-depleted complement-inactivated sera from 165 cases and 61 controls. A multiplex opsonophagocytosis assay (MOPA) was conducted on sera from 20 cases and 20 controls. Neutralizing and opsonizing titers were calculated with antigen-specific IgG titers to determine antibody potency for pneumolysin, pneumococcal conjugate vaccine (PCV) polysaccharides, and non-PCV polysaccharides. There was no significant difference in antibody potencies between cases and controls for the antigens tested. Antipneumolysin neutralizing titers increased with the number of episodes of acute OM, but antibody potency did not. Pneumolysin antibody potency was lower in children colonized with pneumococci than in noncarriers, and this was significant for the otitis-prone group ( P otitis-prone children demonstrates that they respond to the current PCV and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.

    Studies about health-related quality of life (HRQOL) in children with otitis media have primarily focused on short-term effects of the disease, and how treatment with insertion of ventilation tubes (VTs) affects the HRQOL. More knowledge is needed about how long-term HRQOL is associated with different factors like insertion of VT and use of antibiotics. We aimed to analyse HRQOL in children with otitis media 1 year after inclusion and to what extent insertion of VT, use of antibiotics, diagnoses, symptoms in the children, day-care attention, parental absence from work and parental smoking were associated with the long-term HRQOL in children with otitis media. A cohort study including 397 children was carried out. The children were followed for 13 months, and symptoms, HRQOL and so on were identified by means of questionnaires. HRQOL in children with otitis media was significantly improved after 13 months. The improvement of HRQOL was significantly lower for children with sleep problems compared with children without sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work during the preceding 3 months due to the child' s otitis media compared with children with parents not being absent from their work. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period compared with children without a VT. HRQOL in children with otitis media was significantly improved after 13 months. The improvement in HRQOL was significantly lower for children with sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work due to the child's otitis media. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period.

O objetivo deste trabalho foi revisar artigos sobre o impacto das otites médias sobre a aquisição da linguagem em crianças. FONTES DOS DADOS: Foram selecionados artigos catalogados na base Medline com os descritores otite média, linguagem, audição e criança. SÍNTESE DOS DADOS: A revisão de literatura mostrou que a perda auditiva observada nas otites médias pode ser resultante de: (1 alterações estruturais na orelha média, (2 lesões ultra-estruturais e anormalidades bioquímicas na cóclea, ou (3 alterações nas vias auditivas centrais. Cerca de 50% dos casos de otite média secretora, por exemplo, são acompanhados de perda auditiva leve e flutuante. Os dados de literatura apontam que os três primeiros anos de vida são críticos para o desenvolvimento da linguagem, e crianças com otites médias, nesse período, têm maior risco de apresentar distúrbios na aquisição da linguagem, no comportamento e, futuramente, no aprendizado escolar. CONCLUSÕES: As principais conseqüências das otites médias e da perda auditiva sobre a linguagem nessas crianças são erros fonéticos e de articulação da fala, bem como dificuldade para compreensão da leitura.OBJECTIVE: To review the literature concerning the impact of otitis media on language acquisitions in children.

    Conclusions: Together with our previous studies, the current data reveal a conserved role for BIG3 in regulating alpha- and beta-cell functions. We propose that BIG3 negatively regulates hormone production at the secretory granule biogenesis stage and that such regulatory mechanism may be used in secretory pathways of other endocrine cells.

    Krysiak, Robert; Okopien, Bogusław

    2013-01-01

    This study was designed to investigate whether metformin affects monocyte secretory function in patients with impaired fasting glucose receiving chronic statin therapy. The study included 48 patients with impaired fasting glucose treated for at least three months with simvastatin (40 mg daily). These patients were randomized to either metformin (3 g daily) or placebo, which was administered together with simvastatin for 90 days. Plasma lipids, glucose homeostasis markers, monocyte cytokine release and plasma C-reactive protein levels were determined before randomization and at the end of the treatment. Compared to placebo, metformin reduced monocyte release of tumor necrosis factor-α, interleukin-1β, interleukin-6, monocyte chemoattractant protein-1 and interleukin-8, as well as decreased plasma C-reactive protein levels, which were accompanied by an improvement in insulin sensitivity. The obtained results suggest that metformin may inhibit monocyte secretory function and reduce systemic inflammation in statin-treated patients with prediabetes. Impaired fasting glucose patients with high cardiovascular risk may receive the greatest benefits from concomitant treatment with a statin and metformin. Copyright © 2013 Elsevier Inc.

Inclusion criteria for tympanogenic meningitis were acute meningitis with histopathological evidence of chronic otitis media, and no other source of infection. The presence of labyrinthitis and pathologic changes such as granulation tissue, fibrosis, cholesterol granuloma, cholesteatoma, tympanic membrane perforation, tympanosclerosis, and the type of effusion were noted. The extent and location of bacteria embedded in a fibrous matrix were also explored. Seventeen temporal bones, from nine cases that included two females and seven males, ranging in age from five to twenty-three months, met our criteria of tympanogenic meningitis. Eighty two percent of these temporal bones had bacteria within the fibrous matrices (BFM). BFM were located in one anatomical region in one temporal bone and multiple anatomic regions in sixteen temporal bones. The most common locations were the areas near the oval and round windows. They were also commonly seen in the epitympanum, facial recess, and supratubal recess. BFM within the inner ear were observed in the scala tympani and modiolus in the middle and basal turns of the cochleae of nine temporal bones. In one of these temporal bones, BFM were seen in the internal auditory canal. Labyrinthitis was seen in all ears. The tympanic membrane was intact in all cases. BFM were not seen in three temporal bones from two patients. In one case only one side was available for study. Our findings show an association between the presence of BFM in the ear with chronic pathologic changes and tympanogenic meningitis. Potential pathways of bacteria from the middle ear include hematogeous spread and/or direct spread to dura through the tympanic

    In a study of the middle ear cleft in otitis media with effusion (OME), high-resolution computed tomography was performed in 51 patients aged 3 to 13 years. The patients were divided into the following three groups; group I, fresh cases without any treatment; group II, recurrent or chronic cases; group III, cases with sequelae as a result of OME. 1) In group I, the entire middle ear cavity was occupied with material of soft-tissue density in 18 out of 21 ears. The incidence of soft-tissue density was 100% in the mastoid air cells, 95% in the mastoid antrum, 93% in the attic and 88% in the tympanic cavity. The percentage thus rose with the distance from the tympanic cavity. 2) There was no significant difference in the incidence of soft-tissue density between groups I and II. 3) In group III, the mastoid air cells showed density, while the other regions had adequate air-containing spaces. 4) Even after myringotomy and aspiration of the fluid in group I, density was found in the mastoid air cells in 100% of the cases. Density in the mastoid antrum, attic and tympanic cavity was present in 43%, 21% and 21% of the cases, respectively. These results suggest that lesions are likely to persist in regions away from the orifice of myringotomy and that this therapy can not eliminate all of the lesions. In group II, the soft-tissue density in the middle ear was eliminated by myringotomy better than in group I. 5) The effect of ventilating tubes on the mastoid air cells was not determined and requires further studies.

    Otitis media with effusion (OME) may be caused by various factors including Eustachian tube dysfunction, inflammatory response as well as atopy. Allergic rhinitis (AR), a common chronic disorder in children, is associated with swelling of the mucosa and can therefore result in Eustachian tube dysfunction. This study aims to compare the prevalence of OME in subjects with and without AR. Children aged 4-12 were recruited from the clinics at Kwong Wah Hospital, Hong Kong. Subjects recruited were interviewed and a questionnaire filled in regarding nasal obstruction, rhinorrhea, sneezing, itching of the nose and/or post nasal discharge (ARIR document). The children were then examined by a doctor using a pneumatic otoscopy and a portable tympanometer. Children found to have OME were offered a follow-up visit 3 months later. 12 out of 159 (7.5%) of the AR group were found to have OME compared with 3 out of 185 (1.6%) in the non-AR group, p=0.016. During the 2nd visit at 3 months, 85.7% of the AR subjects showed resolution of their OME. Our data showed a significant difference in the prevalence of OME between AR and non-AR subjects. Of the 185 non AR subjects (Control group), 3 was found to have OME, suggesting a point prevalence of OME of 1.6% in the community in Hong Kong. OME is more likely to occur in children with allergic rhinitis and it may be wiser to manage OME in these individuals differently. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  12. The evolution of plant secretory structures and emergence of terpenoid chemical diversity.

    2015-01-01

    Secretory structures in terrestrial plants appear to have first emerged as intracellular oil bodies in liverworts. In vascular plants, internal secretory structures, such as resin ducts and laticifers, are usually found in conjunction with vascular bundles, whereas subepidermal secretory cavities and epidermal glandular trichomes generally have more complex tissue distribution patterns. The primary function of plant secretory structures is related to defense responses, both constitutive and induced, against herbivores and pathogens. The ability to sequester secondary (or specialized) metabolites and defense proteins in secretory structures was a critical adaptation that shaped plant-herbivore and plant-pathogen interactions. Although this review places particular emphasis on describing the evolution of pathways leading to terpenoids, it also assesses the emergence of other metabolite classes to outline the metabolic capabilities of different plant lineages.

    Full Text Available Abstract Background Recurrent otitis media is a common problem in young children. Echinacea and osteopathic manipulative treatment have been proposed as preventive measures, but have been inadequately studied. This study was designed to assess the efficacy of Echinacea purpurea and/or osteopathic manipulative treatment (OMT for prevention of acute otitis media in otitis-prone children. Methods A randomized, placebo-controlled, two-by-two factorial trial with 6-month follow-up, conducted 1999 – 2002 in Tucson, Arizona. Patients were aged 12–60 months with recurrent otitis media, defined as three or more separate episodes of acute otitis media within six months, or at least four episodes in one year. Ninety children (44% white non-Hispanic, 39% Hispanic, 57% male were enrolled, of which 84 had follow-up for at least 3 months. Children were randomly assigned to one of four protocol groups: double placebo, echinacea plus sham OMT, true OMT (including cranial manipulation plus placebo echinacea, or true echinacea plus OMT. An alcohol extract of Echinacea purpurea roots and seeds (or placebo was administered for 10 days at the first sign of each common cold. Five OMT visits (or sham treatments were offered over 3 months. Results No interaction was found between echinacea and OMT. Echinacea was associated with a borderline increased risk of having at least one episode of acute otitis media during 6-month follow-up compared to placebo (65% versus 41%; relative risk, 1.59, 95% CI 1.04, 2.42. OMT did not significantly affect risk compared to sham (44% versus 61%; relative risk, 0.72, 95% CI 0.48, 1.10. Conclusion In otitis-prone young children, treating colds with this form of echinacea does not decrease the risk of acute otitis media, and may in fact increase risk. A regimen of up to five osteopathic manipulative treatments does not significantly decrease the risk of acute otitis media. Trial registration ClinicalTrials.gov Identifier: NCT00010465

  17. Indirect pathogenicity of Haemophilus influenzae and Moraxella catarrhalis in polymicrobial otitis media occurs via interspecies quorum signaling.

    Otitis media (OM) is among the leading diseases of childhood and is caused by opportunists that reside within the nasopharynx, such as Haemophilus influenzae and Moraxella catarrhalis. As with most airway infections, it is now clear that OM infections involve multiple organisms. This study addresses the hypothesis that polymicrobial infection alters the course, severity, and/or treatability of OM disease. The results clearly show that coinfection with H. influenzae and M. catarrhalis promotes the increased resistance of biofilms to antibiotics and host clearance. Using H. influenzae mutants with known biofilm defects, these phenotypes were shown to relate to biofilm maturation and autoinducer-2 (AI-2) quorum signaling. In support of the latter mechanism, chemically synthesized AI-2 (dihydroxypentanedione [DPD]) promoted increased M. catarrhalis biofilm formation and resistance to antibiotics. In the chinchilla infection model of OM, polymicrobial infection promoted M. catarrhalis persistence beyond the levels seen in animals infected with M. catarrhalis alone. Notably, no such enhancement of M. catarrhalis persistence was observed in animals infected with M. catarrhalis and a quorum signaling-deficient H. influenzae luxS mutant strain. We thus conclude that H. influenzae promotes M. catarrhalis persistence within polymicrobial biofilms via interspecies quorum signaling. AI-2 may therefore represent an ideal target for disruption of chronic polymicrobial infections. Moreover, these results strongly imply that successful vaccination against the unencapsulated H. influenzae strains that cause airway infections may also significantly impact chronic M. catarrhalis disease by removing a reservoir of the AI-2 signal that promotes M. catarrhalis persistence within biofilm.

    Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is histologically characterized by systemic necrotizing vasculitis and is clinically classified into two phases, systemic or localized. Recently, otological symptoms such as otitis media and hearing loss, not previously often associated with AAV, have been reported in AAV cases. In these cases we propose a diagnosis of otitis media with AAV (OMAAV). The ANCA titer is important for the diagnosis of OMAAV, and in most cases rapid progressive hearing loss is observed as localized AAV. Peripheral facial nerve palsy or hypertrophic pachymeningitis are coupled with 25% of cases and 18% of cases respectively. Proteinase 3-ANCA (PR3-ANCA) positive otitis media causes granulomatous formation or middle ear effusion in the middle ear, on the other hand myeloperoxidase-ANCA (MPO-ANCA) positive otitis media predominantly presents as otitis media with effusion. The early diagnosed case and the sensorineural hearing loss not progressed deaf could be recovered by the immunosuppressive therapy. Delayed diagnosis of AAV occasionally leads to progression to the irreversible phase; therefore, diagnosis at the early-localized stage is important for treating AAV. In this review, we discuss the current understanding of this newly proposed concept of OMAAV.

    Full Text Available Abstract Background Otitis media is one of the most common infections of early childhood. Surfactant protein A functions as part of the innate immune response, which plays an important role in preventing infections early in life. This prospective study utilized a candidate gene approach to evaluate the association between polymorphisms in loci encoding SP-A and risk of otitis media during the first year of life among a cohort of infants at risk for developing asthma. Methods Between September 1996 and December 1998, women were invited to participate if they had at least one other child with physician-diagnosed asthma. Each mother was given a standardized questionnaire within 4 months of her infant's birth. Infant respiratory symptoms were collected during quarterly telephone interviews at 6, 9 and 12 months of age. Genotyping was done on 355 infants for whom whole blood and complete otitis media data were available. Results Polymorphisms at codons 19, 62, and 133 in SP-A1, and 223 in SP-A2 were associated with race/ethnicity. In logistic regression models incorporating estimates of uncertainty in haplotype assignment, the 6A4/1A5haplotype was protective for otitis media among white infants in our study population (OR 0.23; 95% CI 0.07,0.73. Conclusion These results indicate that polymorphisms within SP-A loci may be associated with otitis media in white infants. Larger confirmatory studies in all ethnic groups are warranted.

    Nattokinase has been reported as an oral health product for the prevention of atherosclerosis. We developed a novel strategy to express a nattokinase from Bacillus subtilis in a live delivery vehicle, Lactococcus lactis. Promoter P( nisZ) and signal peptide SP(Usp) were used for inducible and secretory expression of nattokinase in L. lactis. Western blotting analysis demonstrated that nattokinase was successfully expressed, and about 94% of the enzyme was secreted to the culture. The recombinant nattokinase showed potent fibrinolytic activity, equivalent to 41.7 urokinase units per milliliter culture. Expression and delivery of such a fibrinolytic enzyme in the food-grade vehicle L. lactis would facilitate the widespread application of nattokinase in the control and prevention of thrombosis diseases.

    The human secretory phospholipase A2 group IIA (PLA2-IIA) is a lipolytic enzyme. Its inhibition leads to a decrease in eicosanoids levels and, thereby, to reduced inflammation. Therefore, PLA2-IIA is of high pharmacological interest in treatment of chronic diseases such as asthma and rheumatoid arthritis. Quercetin and naringenin, amongst other flavonoids, are known for their anti-inflammatory activity by modulation of enzymes of the arachidonic acid cascade. However, the mechanism by which flavonoids inhibit Phospholipase A2 (PLA2) remained unclear so far. Flavonoids are widely produced in plant tissues and, thereby, suitable targets for pharmaceutical extractions and chemical syntheses. Our work focuses on understanding the binding modes of flavonoids to PLA2, their inhibition mechanism and the rationale to modify them to obtain potent and specific inhibitors. Our computational and experimental studies focused on a set of 24 compounds including natural flavonoids and naringenin-based derivatives. Experimental results on PLA2-inhibition showed good inhibitory activity for quercetin, kaempferol, and galangin, but relatively poor for naringenin. Several naringenin derivatives were synthesized and tested for affinity and inhibitory activity improvement. 6-(1,1-dimethylallyl)naringenin revealed comparable PLA2 inhibition to quercetin-like compounds. We characterized the binding mode of these compounds and the determinants for their affinity, selectivity, and inhibitory potency. Based on our results, we suggest C(6) as the most promising position of the flavonoid scaffold to introduce chemical modifications to improve affinity, selectivity, and inhibition of PLA2-IIA by flavonoids.

    Precise coordination of protein biogenesis, traffic and homeostasis within the early secretory compartment (ESC) is key for cell physiology. As a consequence, disturbances in these processes underlie many genetic and chronic diseases. Dynamic imaging methods are needed to follow the fate of cargo proteins and their interactions with resident enzymes and folding assistants. Here we applied the Halotag labelling system to study the behavior of proteins with different fates and roles in ESC: a chaperone, an ERAD substrate and an aggregation-prone molecule. Exploiting the Halo property of binding covalently ligands labelled with different fluorochromes, we developed and performed non-radioactive pulse and chase assays to follow sequential waves of proteins in ESC, discriminating between young and old molecules at the single cell level. In this way, we could monitor secretion and degradation of ER proteins in living cells. We can also follow the biogenesis, growth, accumulation and movements of protein aggregates in the ESC. Our data show that protein deposits within ESC grow by sequential apposition of molecules up to a given size, after which novel seeds are detected. The possibility of using ligands with distinct optical and physical properties offers a novel possibility to dynamically follow the fate of proteins in the ESC.

    Full Text Available During placenta development, a succession of complex molecular and cellular interactions between the maternal endometrium and the developing embryo ensures reproductive success. The precise mechanisms regulating this maternal-fetal crosstalk remain unknown. Our study revealed that the expression of Rac1, a member of the Rho family of GTPases, is markedly elevated in mouse decidua on days 7 and 8 of gestation. To investigate its function in the uterus, we created mice bearing a conditional deletion of the Rac1 gene in uterine stromal cells. Ablation of Rac1 did not affect the formation of the decidua but led to fetal loss in mid gestation accompanied by extensive hemorrhage. To gain insights into the molecular pathways affected by the loss of Rac1, we performed gene expression profiling which revealed that Rac1 signaling regulates the expression of Rab27b, another GTPase that plays a key role in targeting vesicular trafficking. Consequently, the Rac1-null decidual cells failed to secrete vascular endothelial growth factor A, which is a critical regulator of decidual angiogenesis, and insulin-like growth factor binding protein 4, which regulates the bioavailability of insulin-like growth factors that promote proliferation and differentiation of trophoblast cell lineages in the ectoplacental cone. The lack of secretion of these key factors by Rac1-null decidua gave rise to impaired angiogenesis and dysregulated proliferation of trophoblast cells, which in turn results in overexpansion of the trophoblast giant cell lineage and disorganized placenta development. Further experiments revealed that RAC1, the human ortholog of Rac1, regulates the secretory activity of human endometrial stromal cells during decidualization, supporting the concept that this signaling G protein plays a central and conserved role in controlling endometrial secretory function. This study provides unique insights into the molecular mechanisms regulating endometrial secretions

    Secretory immunoglobulins (SIg) are a major fraction of the mucosal immune system and represent potential drug candidates. So far, platform technologies for their purification do not exist. SIg from animal whey was used as a model to develop a simple, efficient and potentially generic chromatographic purification process. Several chromatographic stationary phases were tested. A combination of two anion-exchange steps resulted in the highest purity. The key step was the use of a small-porous anion exchanger operated in flow-through mode. Diffusion of SIg into the resin particles was significantly hindered, while the main impurities, IgG and serum albumin, were bound. In this step, initial purity was increased from 66% to 89% with a step yield of 88%. In a second anion-exchange step using giga-porous material, SIg was captured and purified by step or linear gradient elution to obtain fractions with purities >95%. For the step gradient elution step yield of highly pure SIg was 54%. Elution of SIgA and SIgM with a linear gradient resulted in a step yield of 56% and 35%, respectively. Overall yields for both anion exchange steps were 43% for the combination of flow-through and step elution mode. Combination of flow-through and linear gradient elution mode resulted in a yield of 44% for SIgA and 39% for SIgM. The proposed process allows the purification of biologically active SIg from animal whey in preparative scale. For future applications, the process can easily be adopted for purification of recombinant secretory immunoglobulin species. Copyright © 2017 Elsevier B.V. All rights reserved.
