Abstract
OBJECTIVE Inflammatory mediators (IMs) play a major role in the production of middle ear effusion (MEE). Tumor necrosis factor (TNF)-alpha and leukotrienes (LTs) appear to be important in the pathogenesis of otitis media with effusion (OME). The purpose of this study is to determine the effect of TNF-alpha and LT antagonist on the outcome of experimental immune-mediated OME. STUDY DESIGN Prospective. METHODS Otitis media was induced in rats by injecting keyhole limpet hemocyanin (KLH) transtympanically 7 days after systemic immunization. Experimental groups were treated with soluble TNF receptor type I (sTNF RI) or oxatomide simultaneously. Seventy-two hours after transtympanic injection, MEE was aspirated, and temporal bone was taken. Vascular permeability (VP) of the middle ear mucosa was measured using the Evans blue dye technique. Hematoxylin-eosin stain and immunohistochemical stain for leukocyte common antigen was performed. RESULTS In KLH, sTNF RI, and oxatomide groups, MEE was developed in 83%, 0%, and 66% of the ears, respectively. The sTNF RI group showed significant decrease in effusion production, inflammation, mucosal thickening, and VP compared with the KLH group. These parameters were less significant in the oxatomide group than in the sTNF RI group. CONCLUSION Transtympanic administration of sTNF RI and oxatomide appears to suppress the development of immune-mediated MEE.

Abstract
OBJECTIVE Published data indicates that antibiotic use for pediatric respiratory tract infections has declined across the United States. We reviewed antibiotic use in 2 pediatrics practices in Memphis, Tennessee, to determine whether there has been a reduction in inappropriate antibiotic use in this region. METHODS Randomly selected charts in 7 offices of 2 practices were reviewed for respiratory tract infection visits during alternate years between 1992 and 2002. Antibiotics were considered inappropriate for viral respiratory tract and other viral syndromes, asthma, allergic rhinitis, and otitis media with effusion. Changes in inappropriate prescribing were evaluated by generalized estimating equations with year of visit as the explanatory variable and visits clustered by practice. RESULTS There were 1504 unique patient visits reviewed. The number of visits with an antibiotic prescription fell from 85% in 1992 to 67% in 2002. The likelihood of inappropriately prescribing an antibiotic declined between 1992 and 2002 (odds ratio 0.28, 95% confidence interval 0.20-0.38). Use of amoxicillin-clavulanic acid and azithromycin increased, and amoxicillin use decreased. CONCLUSIONS There has been a marked decline in inappropriate antibiotic use in this region with high prescribing rates. Pediatricians have increased their use of broad-spectrum antibiotic agents for respiratory tract infections. Continuing education of physicians regarding appropriate use should continue to maintain and improve on the gains achieved in the last decade.

Abstract
CONCLUSION The lipopolysaccharide (LPS)-induced chinchilla otitis media (OM) model was proven useful in screening anti-inflammatory agents for topical use. Both 1% rimexolone and 1% dexamethasone are effective in reducing the volume of middle ear effusion and mucosal thickness compared with control groups. Topical corticosteroid therapy was efficacious in reducing middle ear mucosal inflammation. OBJECTIVE OM is one of the most common diseases in the pediatric population. Our previous studies have shown that treatment with systemic antibiotics and corticosteroids was more efficacious than antibiotics alone. The purpose of this study was to determine the effectiveness of topically applied corticosteroids on the outcome of OM. The long-term goal of this study was to develop a better method of OM treatment by demonstrating effectiveness of topically applied anti-inflammatory agents, such as corticosteroids, avoiding systemic side effects. MATERIALS AND METHODS Three experimental groups were studied in chinchillas. OM with effusion was induced in all groups by injecting LPS. Group 1 consisted of controls in three subgroups as follows. Control-LPS alone, vehicle of dexamethasone (control-dexa), vehicle of rimexolone (control-rimex). Group 2 was treated with dexamethasone and included subgroups of separate concentrations of dexamethasone: 0.1% and 1% suspensions. Group 3 was treated with rimexolone and included subgroups of separate concentrations of rimexolone: 0.1% and 1% suspensions. A total of 58 animals were used: 18 for controls and 40 for experimental groups. All test substances (saline, control-dexa, control-rimex, dexamethasone and rimexolone, 200 microl) were injected at -2, 48 and 60 h; LPS was injected at 0 h. Animals were monitored by daily otomicroscopy. After 4 days, samples of middle ear effusion (MEE) were collected for analysis and temporal bones were harvested for histopathological studies. RESULTS At the end of 4 days, only in five ears (3/20 with 1% dexamethasone, 1/20 with 1% rimexolone, and 1/20 with 0.1% rimexolone) had the fluid diminished to the point of being unobservable. The volume of MEE, thickness of mucoperiosteum, and the degree of inflammation of middle ear mucosa with 1% dexamethasone and 1% rimexolone was significantly less compared with other groups.

Abstract
OBJECTIVE To study the relationship between the fibrinogen content in middle ear effusion (MEE) and the protracted inflammation of secretory otitis media (SOM) and to explore the possible mechanism of batroxobin in treatment of SOM. METHODS The fibrinogen content of middle ear effusion from 156 patients with SOM was investigated with concretion technique at different stages. After two times punctuation of tympanum, the recurrence patients were randomly divided into two groups: batroxobin and dexamethasone group, and 0.5 ml (2 BU/ml) batroxobin or dexamethasone (2 mg/ml) was injected into middle ear cavity. The therapeutic effects were investigated. RESULTS The concentration of fibrinogen in the recurrence group of SOM patients was higher than that in the cured group, and even higher in the second recurrence group than in the first recurrence group (P < 0.01). There was significantly different (P < 0.001) in the therapeutic efficacy between the batroxobin group (91.6%) and the dexamethasone group (62. 5%); the difference of the fibrinogen content in MEE and air conduction of pure tone audiometry at frequencies (0.5, 1.0, 2.0 kHz) between the two groups after treatment were also significant (P < 0.01). CONCLUSIONS Fibrinogen may play a significant role in the occurrence and development of secretory otitis media. Batroxobin had better therapeutic effect on SOM than dexamethasone. The mechanism of batroxobin in the treatment of SOM may be that the batroxobin can relief the depressant effect of fibrinogen on surface active agents of the Eustachian tube and prevent the fibrinogen from turning into insoluble fibrin polymer by means of fibrinolysis.

Abstract
BACKGROUND Acute otitis media (AOM) is a spontaneously remitting disease for which pain is the most distressing symptom. Antibiotics are now known to have less benefit than previously assumed. OBJECTIVES To assess the effectiveness of topical analgesia for AOM. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2006), MEDLINE (1966 to May Week 3 2006), EMBASE (1990 to December 2005) and LILACS (1982 to September 2005) without language restriction, and the reference lists of articles. We also contacted manufacturers and authors. SELECTION CRITERIA Double-blind randomised or quasi-randomised controlled trials comparing an otic preparation with an analgesic effect (excluding antibiotics) versus placebo or an otic preparation with an analgesic effect (excluding antibiotics) versus any other otic preparation with an analgesic effect, in adults or children presenting at primary care settings with AOM without perforation. DATA COLLECTION AND ANALYSIS Potential studies were screened independently and trial quality was assessed by three authors, and differences were resolved by discussion. Data was then independently extracted from the trials selected by two authors. We contacted the authors of three trials to acquire additional information not available in published articles. MAIN RESULTS Our searches yielded 356 records; four trials met our criteria. One trial with 54 participants compared treatment with anaesthetic ear drops versus an olive oil placebo immediately at diagnosis. All patients were also given paracetamol. There was a statistically significant pain reduction of 25% in those receiving anaesthetic drops 30 minutes after instillation. Three trials (with one common co-author) compared anaesthetic ear drops with naturopathic herbal ear drops in 274 patients. One of these trials also used antibiotics in both groups. There were statistically significant differences at instillation of drops, or 15 or 30 minutes after the instillation (or both) on one to three days after diagnosis, always favouring the naturopathic group in each trial. AUTHORS' CONCLUSIONS The evidence from these four randomised controlled trials, only one of which addresses the most relevant question of primary effectiveness, is insufficient to know whether ear drops are effective or not.

Abstract
BACKGROUND Otitis media with effusion (OME) is common and may cause hearing loss with associated developmental delay. Treatment remains controversial. OBJECTIVES To examine evidence for or against treating children with hearing loss associated with OME with systemic or topical intranasal steroids. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library Issue 4 2005, MEDLINE (1966 to 2006), EMBASE (1974 to 2006), and the CINAHL, LILACS, Zetoc, IndMED, SAMED, KoreaMed, MEDCARIB and Cambridge Scientific Abstracts databases in January 2006. SELECTION CRITERIA Randomised controlled trials of oral and topical intranasal steroids, either alone or in combination with another agent such as an antibiotic, were included. EXCLUSIONS publications in abstract form only; uncontrolled, non-randomised or retrospective studies; studies reporting outcomes with ears (rather than children). DATA COLLECTION AND ANALYSIS Data were extracted from the published reports by the authors independently using standardised data extraction forms and methods. The methodological quality of the included studies was independently assessed by the authors as described in the Cochrane Handbook. Dichotomous results were expressed as an odds ratio using a fixed-effect model together with the 95% confidence intervals. Continuous data were analysed using the weighted mean difference in a fixed-effect model. Tests for heterogeneity between studies were performed using a Mantel-Haenszel approach. In trials with a cross-over design, post cross-over treatment data were not used. MAIN RESULTS No study prospectively documented hearing loss associated with OME prior to randomisation. Follow up was mainly short term. The odds ratio for OME persisting after short-term follow up in children treated with oral steroids compared to control was 0.22 (95% CI 0.08 to 0.63). The odds ratio for OME persisting after short-term follow up for children treated with oral steroids plus antibiotic compared to control plus antibiotic was 0.37 (95% CI 0.25 to 0.56). However, there was significant heterogeneity between studies included in the latter comparison (P < 0.01). Trends favoured steroids for most other comparisons, but confidence intervals included unity. There was no evidence of benefit for steroid treatment for OME or hearing loss associated with OME in the longer term. AUTHORS' CONCLUSIONS Both oral and topical intranasal steroids alone or in combination with an antibiotic lead to a quicker resolution of OME in the short term, however, there is no evidence of longer term benefit.

Abstract
Acute otitis media (AOM) and otitis media with effusion (OME) are common diseases in childhood. Alloiococcus otitidis is a newly recognized species of gram-positive bacterium which was recently discovered as a pathogen associated with OME. Although some studies show that A. otitidis is frequently detected in children with OME, no study is available concerning the clinical efficiency of antibiotics against this organism. The prevalence of A. otitidis in 116 middle ear effusion specimens from 36 AOM and 52 OME patients was examined by culture and PCR. In addition, the prevalence of the bacterium was retrospectively investigated in relation to antibiotic use. A. otitidis was detected in 20 (50%) AOM and 47 (61%) OME specimens. The organism was the most frequent bacterium in AOM as well as in OME and was highly detected even in patients who had been treated with antibiotics, such as beta-lactams or erythromycin. The incidence of A. otitidis in our study was higher than that in Western countries, and our results suggest that drug-resistant strains of A. otitidis may be frequently spread in Japanese children. Our study suggests that antibiotics such as beta-lactams or erythromycin may not be sufficiently effective to eliminate this organism. Further investigation is expected to reveal the clinical role of the organism in otitis media.

Abstract
OBJECTIVES We evaluated the in vitro antibacterial activity of amoxicillin against penicillin-susceptible and -nonsusceptible Streptococcus pneumoniae strains isolated from children with acute otitis media (AOM). METHODS Children more than 3 months of age with AOM who were seen in the Dr Sótero del Rio and Luis Calvo Mackenna Hospitals in Santiago, Chile, between July 1998 and December 2002 were subjected to tympanic puncture for middle ear fluid culture. The penicillin and amoxicillin susceptibilities of the S pneumoniae isolates were determined by epsilometer test (E test). RESULTS A bacterial pathogen was isolated in 432 of 543 children (80%) as follows: S pneumoniae, 40%; Haemophilus influenzae, 29%; Moraxella catarrhalis, 7%; and Streptococcus pyogenes, 4%. Penicillin-susceptible S pneumoniae strains were less common than amoxicillin-susceptible strains (60% versus 95%; odds ratio [OR], 0.08; 95% confidence interval [CI], 0.04 to 0.18). Both intermediate- and high-resistance strains were more common for penicillin (22% versus 4.5%; OR, 5.6; 95% CI, 2.5 to 12.7) than for amoxicillin (18% versus 0.5%; OR, 41.3; 95% CI, 6.0 to 821). CONCLUSIONS Penicillin resistance is not extrapolable to amoxicillin among S pneumoniae strains isolated from middle ear fluid of children with AOM. Our results support the recommendation to evaluate the minimal inhibitory concentrations of penicillin-nonsusceptible S pneumoniae for amoxicillin and to continue use of this antimicrobial as a first-line antimicrobial choice for children with AOM.

Abstract
OBJECTIVES Topical steroid treatment can be a powerful alternative to surgery in controlling adenoid hypertrophy and otitis media with effusion (OME). METHODS A prospective, controlled, randomized, clinical study in an academic tertiary care center. A total of 122 children (3-15-year-old) on the waiting list for an adenoidectomy and/or ventilation tube placement were enrolled into the study and control groups. The study group (67 patients with adenoid hypertrophy, 34 of them with otitis media with effusion) received intranasal mometasone furoate monohydrate 100 mcg/day, and the control group (55 patients with adenoid hypertrophy, 29 of them with otitis media with effusion) was followed up without any treatment. All patients were evaluated at 0 and 6 weeks. The assessment of each patient included history, a symptom questionnaire, a skin prick test, a tympanogram, if possible a pure tone audiogram, and otoscopic and endoscopic examinations. The size of adenoid tissue was graded as a percentage according to obliteration of the choanae. The adenoid/choana ratio (A/C) was recorded for each patient. Symptoms were scored as 0 (absent), 1 (intermittent/periodic), or 2 (continuous). The data were analyzed with the "Statistical Package for the Social Sciences" (SPSS 9.0) using the appropriate nonparametric tests for nominal and ordinal data. RESULTS Resolution of otitis media with effusion in the study group (42.2%) was significantly higher than that in the control group (14.5%) (p<0.001). Forty-five patients (67.2%) with adenoid hypertrophy in the study group showed a significant decrease in adenoid size according to the endoscopic evaluation compared to the control group (p<0.001). A significant improvement in obstructive symptoms was seen in the study group (p<0.001). The endoscopically measured adenoid/choana ratio and degree of obstructive symptoms showed a significant correlation (r=0.838 p<0.001, r=0.879 p<0.001, r=0.838 p<0.001, r=0.879 p<0.001). The adenoid/choana ratio improved significantly in atopic patients in the study group (p<0.05), whereas in atopic patients in the control group there was no change (p=0.221). CONCLUSION Nasal mometasone furoate monohydrate treatment can significantly reduce adenoid hypertrophy and eliminate obstructive symptoms. It is a useful alternative to surgery, at least in the short term, for otitis media with effusion.

Abstract
In this study, the anti-inflammatory effect of erythromycin was investigated in a model of histamine-induced otitis media with effusion (OME). OME was induced in guinea pigs by the transtympanic injection of histamine solution into the middle-ear cavity. Guinea pigs were randomly assigned to one of three groups: control, erythromycin treatment, or methylprednisolone treatment. After histamine injection, the animals were treated with intraperitoneal medication for five days consecutively. Afterwards, the animals were sacrificed and the temporal bones were removed. The samples were examined stereologically.In the erythromycin-treated group, it was observed that neutrophil infiltration was significantly inhibited when compared to the control group. This result shows that erythromycin may produce a significant anti-inflammatory effect in this model of OME.

Abstract
BACKGROUND Disappearance of middle ear effusion is one of the most important outcomes in the treatment of acute otitis media (AOM). AIM To evaluate the duration of effusion in AOM treated by antimicrobials and to find factors influencing it. METHODS Parents of 90 children with AOM monitored daily the disappearance of effusion with tympanometry. The children were randomly allocated to be treated with either oral amoxicillin or cefuroxime-axetil for 10 d. Daily monitoring lasted for 14 d or until the tympanogram was normal (curve A or C) in both ears. Pneumatic otoscopy was carried out every 2 wk. RESULTS Normal tympanograms were obtained after a median time of 7.5 d (range 1-58 d) among 75 successfully monitored patients. In two-thirds (69%) of them, effusion resolved in 14 d. The median duration of effusion did not differ significantly between the two treatment groups (8 vs 7 days, p=0.7). The children who had unilateral AOM cured more rapidly than those with bilateral AOM (5 vs 19 d, p<0.001). In logistic regression analysis adjusted for age, bilaterality explained treatment failure at 2 wk with an odds ratio of 28.1 (95% CI 4.6-169.5, p<0.001). CONCLUSION The choice of antimicrobials did not influence the duration of middle ear effusion, which was much shorter than had been thought previously. Children with unilateral AOM were cured much more quickly than those with bilateral AOM.

Abstract
CONCLUSION A high prevalence of penicillin-binding protein gene-mutated (PGM) strains of Haemophilus influenzae should be taken into account when treating otitis media in children. OBJECTIVE To evaluate the prevalence of beta-lactamase-non-producing ampicillin-resistant strains of H. influenzae with mutations in the ftsI gene encoding penicillin-binding protein 3 (PBP3) among children with otitis media. MATERIAL AND METHODS A total of 644 nasopharyngeal isolates of H. influenzae were collected from pediatric acute otitis media patients with or without otitis media with effusion at the clinics of the Department of Otolaryngology-Head and Neck Surgery, Wakayama Medical University Hospital and 6 affiliated hospitals in Wakayama Prefecture between January 1999 and December 2003. MICs to ampicillin (AMP), cefdinir (CFD), cefaclor (CCL), cefpodoxime (CPD) and cefcapene (CFPN) were determined by a microbroth dilution method according to the recommendations of the National Committee for Clinical Laboratory Standards. Types of mutations in the PBP3 gene (ftsI) were evaluated by means of a polymerase chain reaction (PCR)-based genotyping method. The beta-lactamase gene (bla) was also identified by means of PCR. RESULTS Beta-lactamase-producing (BLP) strains having the bla gene were identified in 16 isolates (2.5%). PGM strains were identified in 279 isolates (43.3%). There were 242 PGM1-non-BLP strains (37.6%) with mutations in the variable mutated locus of ftsI, 35 PGM2-non-BLP strains (5.4%) with mutations in the highly mutated locus of ftsI and 2 BLP-PGM strains (0.3%) with mutations in ftsI that produced beta-lactamase. BLP-non-PGM strains producing beta-lactamase without mutations in ftsI were identified in 14 isolates (2.2%). MICs of PGM1-non-BLP strains to AMP were 0.5-2.0 microg/ml. The MIC90 of CDN to the PGM1-non-BLP strains was the lowest (0.06 microg/ml). The proportion of PGM1-non-BLP strains increased rapidly during 1999-2002 and then decreased in 2003. In contrast, the proportion of PGM2-non-BLP strains increased in 2003.

Abstract
BACKGROUND Given the relatively high prevalence of recurrent and persistent acute otitis media (AOM) and the prominent etiologic role of Streptococcus pneumoniae, especially penicillin-nonsusceptible strains in children with these conditions, new alternative treatments are desirable. METHODS Children 6 months-4 years of age with AOM considered to be at risk for recurrent or persistent infection received large dosage cefdinir 25 mg/kg oral suspension once daily for 10 days. Children were evaluated pretreatment (day 1), on therapy (days 4-6), end of therapy (days 12-14) and at follow-up (days 25-28). All children had tympanocentesis at enrollment. In culture-positive children, tympanocentesis was repeated after 3-5 days (days 4-6) unless evidence of absence of middle ear effusion was documented. RESULTS Of 447 children enrolled, 230 were clinically and bacteriologically evaluable (74% 2 years old or younger; 57% treated for AOM in previous 3 months). Bacteriologic eradication, based on repeat tympanocentesis on days 4-6, was achieved in 74% (170 of 230) of children; 76% (201 of 266) of AOM pathogens were eradicated. Eradication of penicillin-susceptible, -intermediate and -resistant S. pneumoniae was 91% (50 of 55), 67% (18 of 27) and 43% (10 of 23), respectively (P < 0.001); eradication of H. influenzae was 72% (90 of 125). Overall clinical response at days 12-14 was 83% (76 and 82% for children with S. pneumoniae and Haemophilus influenzae, respectively). Sustained clinical response at days 25-28 was 85%. Clinical response was 83% for culture-positive children versus 96% for culture-negative children at baseline tympanocentesis (P < 0.001). CONCLUSIONS In this study of AOM among children at risk for persistent or recurrent infection, large dose cefdinir resulted in an overall successful clinical response at end of treatment of 83%. This regimen was efficacious against penicillin-susceptible S. pneumoniae, but effectiveness was markedly decreased against nonsusceptible strains and was moderate for H. influenzae strains.

Abstract
BACKGROUND Patients with intractable otitis media associated with bronchial asthma have an extensive accumulation of eosinophils in the effusion and mucosa of the middle ear; this condition is called eosinophilic otitis media (EOM). It remained to be determined how eosinophils accumulate in the middle ear. OBJECTIVES To clarify the pathogenesis of middle ear diseases, we measured the concentration of eosinophil chemoattractants in middle ear effusion (MEE), and carried out immunohistochemical studies of middle ear mucosa specimens to demonstrate the expression of eosinophil chemoattractants. METHODS Middle ear effusion samples were obtained from 15 EOM patients with bronchial asthma and from six controls for the measurement of eosinophil cationic protein (ECP), IL-5, eotaxin and regulated on activation, normal T expressed and secreted concentrations. Middle ear mucosa samples were also taken from 14 EOM patients and 16 controls for immunohistochemical study. In 10 EOM patients, the numbers of immunoreactive cells as well as apoptotic cells were determined before and after the topical application of triamcinolone acetonide into the middle ear. RESULTS In EOM, significantly higher ECP and IL-5 concentrations were detected in MEE than in serum, and ECP, IL-5 and eotaxin concentrations in MEE were higher in the EOM patients than in the controls. ECP concentration positively correlated with that of IL-5. Immunohistochemically, the numbers of cells positive for EG2 and ecalectin were significantly higher in the EOM patients than in the controls. After the topical application of triamcinolone acetonide, the numbers of infiltrating cells and immunoreactive cells distinctly decreased, whereas the number of apoptotic cells significantly increased. CONCLUSION In EOM, locally produced IL-5 may play a crucial role in the accumulation of eosinophils in the middle ear. Chemokines such as ecalectin and eotaxin are also produced in the middle ear, and help activate and enhance the survival of eosinophils to induce the intractable condition in the middle ear. The topical application of triamcinolone acetonide induces the apoptosis of not only eosinophils but also eosinophil chemoattractant-producing cells, thereby improving the middle ear condition.

Abstract
The inhibitory effects of ketotifen, a histamine H1-receptor antagonist and mast cell stabilizer, were examined on a non-IgE experimental model of middle ear effusion. Thirty rats were divided into three groups. Group A (n = 9) was subjected to mechanical stimulation of the external auditory canal (EAC); group B (n = 11) was pre-treated with intraperitoneal administration of 0.2 mg ketotifen, 90 min before mechanical stimulation of the EAC; and group C (n = 10), the control group, was neither exposed to mechanical stimulation nor given ketotifen. Thirty minutes after completion of the experiment, the eardrums were inspected, histamine levels were determined by a fluorometric assay, and the pars flaccida underwent histological assessment. An attic effusion was observed in group A; a similar phenomenon but to a lesser extent was also seen in group B. Statistical analysis confirmed that the mean histamine concentration of the rinsing fluid obtained from group A was significantly higher than that of group C (p = 0.004) or group B (p = 0.008). No significant difference was found between the mean histamine concentration of groups C and group B (p = 0.311). Histological assessment revealed that the thickness of the pars flaccida of group A was considerably greater than that of groups C and B and was characterized by marked edema. Furthermore, the pars flaccida mast cell population was significantly depleted compared with groups C and B. The data indicate that mechanical stimulation of the EAC triggered the pars flaccida mast cells to degranulate in a non-mediated IgE fashion and that histamine is implicated in most of these histological changes. It is concluded that administration of ketotifen before mechanical stimulation of the EAC had a stabilizing effect and abolished mast cell degranulation, therefore, may be considered as a potential therapeutic agent for the treatment of middle ear disease in the pediatric population.

Abstract
Allergic rhinitis, rhinosinusitis, and otitis media are among the most common health problems encountered in general practice. Although frequently trivialized, they affect the quality of life, represent a significant socioeconomic burden, and are associated with some serious complications. In addition, allergic rhinitis, rhinosinusitis, and otitis media are often considered as comorbidities. These disorders involve an inflammatory process of the respiratory mucosa of the nose, paranasal sinuses, or middle ear. Because of their well-known anti-inflammatory effects, the role of glucocorticosteroids in the management of these three disorders has been questioned, evaluated, and, in some cases, established.

Abstract
BACKGROUND Secretory otitis media is a common otological manifestation, that most of the time is left undiagnosed on account of unawarenes s and negligence in seeking early medical attention for trivial ailments. Untreated, it might end up in serious consequences in the form of poor speech and intellectual development and permanent anatomical disabilities within middle ear cleft. The objectives of the study were to determine most affected age group, the common etiological factors. to access the efficacy of medical and surgical treatment and finally to find out the coumplication associated with the surgical procedures. METHODS This study was conducted in the ENT, Head and Neck Surgery department of the Ayub Teaching Hospital, Abbottabad from January 2001 to December 2003. Only the diagnosed cases of SOM were included in the study. After detailed history, clinical examination, routine investigations and special investigations such as pure tone audiogram and tympanometry were carried out to confirm the diagnosis of SOM . All patients were initially treated by medical therapy. In cases of failure, underwent myringotomy with or without ventilation tube insertion and where indication present adenotonsillectomy and antial lavage was done. Follow up of cases was carried out from 18-24 months. RESULTS It included 87 patients, 58 were males (66.6%) and 29 females (33.3%). Majority of the patients were between 5-8 years (62%). The most common aetiological factor was rhinosinusitis (36.7%) followed by hypertrophic adenoids (34.5%). All patients were initially given medical treatment. Out of 87 patients,30 patients (34.4%) improved and 57 patients (65.5%) had no response and underwent surgery. Surgical procedures included myringotomy with and without ventilation tube insertion., adenotonsillectomy and antral lavage. CONCLUSION lt is concluded from this study that conservative treatment has a definite role and should be tried before any surgical step is taken however surgery is the treatment of choice in more resistant cases.

Abstract
Cytomegalovirus (CMV) belongs to Herpesvirida family and it occurs quite frequently in the human environment. It is a very important pathogen in persons with suppressed or lowered resistance. Having special kindship with epithelium, it may cause primary infection or reveal secondary influence in the latent form. Congenital CMV infection is a major cause of sensorineural hearing loss and neurological impairment in children. Otogenic complications may develop in patients with viral infection immunodeficiency. Aim of the paper was assessment of lateral sinus thrombosis (LST) in children with acute otitis media (AOM) and CMV infection. Authors present a case of LST in 5-year old child with AOM with mastoiditis and acquired CMV infection. In the first phase a disease appeared as mononucleosis-like infection with developing neurological signs resulting from meningitis. In the second phase the signs of acute otitis media, mastoiditis and lateral sinus thrombosis increased. Despite broad spectrum antibiotics therapy the intracranial complication developed which was surgically treated with good outcome. All the symptoms resulting from mastoiditis, LST and meningitis ceased. Clinical symptoms of the secondary CMV infection are rare in children. Complications may develop despite proper treatment of the ear and throat infections, and may result from immunodeficiency after CMV infection.

Abstract
The management of otitis media with effusion (OME) has received much attention recently as a result of, among other factors, the development of resistant bacteria and the finding of less long-term impact of middle-ear effusion (MEE) on development than previously believed. Guidelines have recently been published for the management of OME promoting more accurate diagnosis, particularly distinguishing acute otitis media from OME, and recommending the 'judicious' use of antibacterials. Today, more emphasis is being placed on prevention of disease by reducing risk factors and the development of vaccines. The identification of susceptibility genes may lead to better understanding of the pathogenesis of otitis media, which in turn may lead to the development of more innovative and satisfactory methods for prevention and treatment.

Abstract
OBJECTIVE To observe the clinical efficacy of Qingqiao Capsule (QQC) in treating patients with secretory otitis media (SOM). METHODS A total of 90 patients were randomly assigned into the treated group (n = 45) and the control group (n = 45). Patients in the treated group were administrated with QQC, 5 capsules each time, 3 times a day for totally 10-14 days, and those in the control group were given per os cefaclor capsules 0.5 g each time for adult, 3 times a day, or 20 mg/(kg.d) for children, for 10-14 days. The therapeutic efficacy of treatment on the patients was observed and compared after treatment and followed up for 3-6 months. RESULTS (1) The clinical efficacy in the treated group was superior to that in the control group with significant statistical difference (P < 0.01); (2) Comparison of the efficacies in patients of three different TCM syndrome types (the external pathogenic wind invasion caused auditory orifice stuffiness type, the Gan-Dan damp-heat steaming up auditory orifice type and the Pi-deficiency dysfunction induced dirty dampness blocking ear type) showed no statistically significant difference (P > 0.05); (3) The vanishing rate and time needed of the main symptoms and signs in the treated group were superior to those in the control group on ear muffle, tinnitus, hearing impairment, hydrotypanum, pure tone threshold and abnormal tongue figure, and the difference was statistically significant (P < 0.05 or P < 0.01), only those of earache, otopiesis and abnormal pulse figure were insignificantly different between the two groups (P > 0.05). CONCLUSION QQC is an effective Chinese composite medicine on patients with SOM, and shows no obvious adverse reaction.

Abstract
Infection with methicillin-resistant Staphylococcus aureus (MRSA) is increasing. It may be community or hospital acquired and is characteristically difficult to eradicate. Here we report a case of a two-year-old girl who sustained a traumatic tympanic membrane perforation following a minor burns injury. She was seen as an out-patient in a burns unit and subsequently developed MRSA otorrhoea. This was treated with a two-week course of fusidic acid topical drops. At three-week follow up the tympanic membrane had healed and the infection had healed completely. Fusidic acid is safe and effective in the treatment of MRSA otorrhoea. We need to maintain vigilance in the treatment of otorrhoea, as MRSA may become an increasingly common pathogen in the future.

Abstract
OBJECTIVE To compare the effects of cefdinir (14 mg/kg per day) and amoxicillin (90 mg/kg per day) antimicrobial therapy on the nasopharyngeal flora of children with acute otitis media. DESIGN Nasopharyngeal cultures for aerobic and facultative bacteria were obtained before therapy and 2 to 4 days after completion of therapy. SETTING Outpatient clinic. PATIENTS Fifty children, aged 7 months to 5 years 4 months. MAIN OUTCOME MEASURES After completion of therapy, 22 (88%) of the 25 patients treated with cefdinir and 16 (64%) of the 25 patients treated with amoxicillin were considered clinically cured (P<.05). A significant reduction in the number of all isolates occurred following therapy in those treated with cefdinir (36 vs 71, P<.01) or with amoxicillin (56 vs 73, P<.05). However, the total number of isolates recovered after therapy was significantly lower in those treated with cefdinir (36) compared with those treated with amoxicillin (56) (P<.01). RESULTS The recovery of potential pathogenic organisms (eg, Streptococcus pneumoniae, Staphylococcus aureus, beta-hemolytic streptococci, Haemophilus species, and Moraxella catarrhalis), as well as penicillin-resistant bacteria, was lower following completion of therapy in the cefdinir group (6 pathogens, including 5 that were penicillin resistant), compared with the amoxicillin group (27 pathogens, including 16 that were penicillin resistant) (P<.01). CONCLUSION This study illustrates the greater ability of cefdinir compared with amoxicillin to reduce the number of potential nasopharyngeal pathogens as well as penicillin-resistant bacteria in children with acute otitis media.

Abstract
BACKGROUND The purpose of this study is to compare the effects of two different doses of 5-fluorouracil (5-FU) on closure rates and histopathological findings in myringotomy to those of simple myringotomy with saline application. MATERIAL/METHODS 36 rats were divided into two study groups and a control group of 12 rats each. After bilateral myringotomy, we applied 5-FU 50 mg/ml in group A, 10 mg/ml in group B and saline in the control group for 10 minutes. Examination was made by otoendoscopy on days 1, 3, 5, 7, 10, 15, 20, 25. After the follow up examination, two rats from each group were randomly sacrificed on days 7, 15, 25 and 35. Both tympanic membranes were investigated for fibrosis and inflammation by light microscopy. RESULTS Most of the tympanic membranes from group B and the control group healed on the 10th day, but 16 myringotomies were patent in group A; by the 25th day, all myringotomies in all three groups were completely healed. The mean healing time was 14.62 days, 10.20 days and 10.40 days respectively in groups A, B and control. Fibrosis and inflammation were less in group A than in group B and the controls. CONCLUSIONS 5-FU at a concentration of 50 mg/mL is effective in prolonging the patency of myringotomies in rat tympanic membranes, while a concentration of 10 mg/mL has no greater effect than a simple myringotomy procedure with saline application.

Abstract
For many years, trimethoprim-sulfamethoxazole (TMP-SMX) has been recommended as an alternative antimicrobial agent for the treatment of children with otitis media (OM). This study analyzed the in vitro activity of TMP-SMX against respiratory pathogens obtained from middle ear fluid of Costa Rican children 6-60 months of age with acute OM, recurrent OM, therapeutic failures and acute OM at risk for having a resistant pathogen. Between 2002 and 2003, a total of 124 middle ear fluid bacterial isolates were analyzed and compared with historic data from 1992 to 1997. A significant increase in the number of TMP-SMX Streptococcus pneumoniae (P = 0.00008)- and Haemophilus influenzae (P = 0.04)-resistant strains was observed during 2002-2003 when compared with strains from 1992-1997.

Abstract
Otorrhea is a symptom and not a diagnosis. It can be caused by many disease processes. There are several reasons to consider topical treatment of otorrhea. Two are that greater concentrations can be reached locally of pharmacologically active agents and there is less risk of systemic complications and side effects. One factor that might prevent their efficacy is the formation of biofilms by pathogenic organisms. Topical treatments usually include antimicrobial agents. There is evidence that aminoglycoside-containing drops can cause ototoxicity, particularly insidious vestibular ototoxicity. Nonaminoglycosides are recommended if there is access to the middle ear. There is some evidence that the addition of steroids hastens resolution. There is little evidence on which to estimate the risk reduction of serious complications of otitis media from treatment with topical therapy. In some causes of otorrhea, nonmicrobial treatments might be just as effective. Individualized therapy is recommended.

Abstract
We investigated the association between prescribing antimicrobial agents and antimicrobial resistance of Streptococcus pneumoniae among children with acute otitis media in southern Israel. During a 6-year period, all prescriptions of a sample of ≈20% of Jewish and Bedouin children <5 years of age were recorded and all pneumococcal isolates from middle ear fluid were collected. Although antimicrobial drug use was significantly higher in Bedouin children, the proportion of S. pneumoniae isolates with penicillin MIC ≥1.0 μg/mL was significantly higher in Jewish children. In both populations, antimicrobial prescriptions were markedly reduced over time, especially for penicillins and erythromycin. In contrast, azithromycin prescriptions increased from 1998 to 2001 with a parallel increase in macrolide and multidrug resistance. Penicillin resistance was associated with macrolide resistance. These findings strongly suggest that azithromycin affects increased antimicrobial resistance, including multidrug resistance, in S. pneumoniae.

Abstract
OBJECTIVE To find a new way of treating otitis media with effusion by studying the curative effect of pulmonary surfactant on secretory otitis media in guinea pigs. METHOD Nonviable heat-killed pneumococci (HKP) solution was inoculated into the middle ear cavity in guinea pig via a transeardrum approach, set up models of otitis media with effusion in guinea pigs, after being injected with pulmonary surfactant by transeardrum approach, observed changes of serous effusion in tympanum and response threshold. RESULT Five days after inoculation of HKB, serous effusion was present in the middle ear cavity of guinea pigs with disappearance of light cone. ABR response threshold raised from (14.00 +/- 3.08) dB to (45.00 +/- 5.67) dB. After seven days following injection of pulmonary surfactant by transeardrum approach, serous effusion of tympanum reduced or disappeared. ABR response threshold decreased from (45.00 +/- 5.67) dB to (23.53 +/- 6.32) dB, there was significantly difference between them (P < 0.001). In guinea pigs suffering from otitis media with effusion were not treated by PS, the serous effusion of tympanum did'nt change. Eardrum was more muddy and ABR response threshold raised from (45.00 +/- 5.67) dB before treatment (65.50 +/- 6.85) dB after being treated by PS, respectively, with statistically significant difference between them (P < 0.01). CONCLUSION Pulmonary surfactant plays an important role in treating otitis media with effusion in guinea pigs.

Abstract
OBJECTIVES Debate continues with respect to a "watch and wait" approach versus immediate antibiotic treatment for the initial treatment of acute otitis media. In this double-blind noninferiority trial, we compared clinical improvement rates at 14 days for children (6 months to 5 years of age) with acute otitis media who were randomly assigned to receive amoxicillin or placebo. METHODS We enrolled healthy children who presented to clinics or the emergency department with a new episode of acute otitis media during the fall and winter months in Ottawa (from December 1999 to the end of March 2002). The children were randomly assigned to receive amoxicillin (60 mg/kg daily) or placebo for 10 days. Telephone follow-up was performed on each of days 1, 2 and 3 and once between day 10 and day 14. The primary outcome was clinical resolution of symptoms, defined as absence of receipt of an antimicrobial (other than the amoxicillin in the treatment group) at any time during the 14-day period. Secondary outcomes were the presence of pain and fever and the activity level in the first 3 days, recurrence rates, and the presence of middle ear effusion at 1 and 3 months. RESULTS According to clinical scoring, 415 of the 512 children who could be evaluated had moderate disease. At 14 days 84.2% of the children receiving placebo and 92.8% of those receiving amoxicillin had clinical resolution of symptoms (absolute difference -8.6%, 95% confidence interval -14.4% to -3.0%). Children who received placebo had more pain and fever in the first 2 days. There were no statistical differences in adverse events between the 2 groups, nor were there any significant differences in recurrence rates or middle ear effusion at 1 and 3 months. INTERPRETATION Our results did not support the hypothesis that placebo was noninferior to amoxicillin (i.e., that the 14-day cure rates among children with clinically diagnosed acute otitis media would not be substantially worse in the placebo group than the treatment group). Nevertheless, delaying treatment was associated with resolution of clinical signs and symptoms in most of the children.

Abstract
OBJECTIVE Otitis media with effusion (OME) is one of the most frequent diseases and the main cause of hearing loss in childhood. The medical treatment for OME includes antibiotics, antihistamine-decongestant combinations, steroids and Eustachian-tube autoinflation as the Valsalva manoeuvre. METHODS A total of 62 children aged 2 to 8 years with a diagnosis of OME were enrolled in a prospective study to assess the resolution of OME. Patients were given antibiotics treatment with or without associated AM3. RESULTS After 2 months of treatment, the rate of complete resolution of OME was greater in AM3 treated group than in the non-AM3 treated group (57.6% vs 27.6%) with a statistically significant difference (p<0.017). CONCLUSIONS These results show that AM3 treatment has a beneficial effect on OME resolution when it is associated to antibiotic treatment.

Abstract
OBJECTIVES To conduct a prospective, randomized, controlled trial determining the feasibility of radiofrequency with or without topical mitomycin C application in delaying the closure time of human tympanostomy and screening its efficacy in management of recurrent acute otitis media and otitis media with effusion. METHODS From November 2002 to January 2004, 96 patients (180 ears) who were to undergo surgical intervention for recurrent acute otitis media or otitis media with effusion were included in this study. Sixty ears with a diagnosis of recurrent acute otitis media were equally randomized to three procedures: cold knife myringotomy (Group A), radiofrequency tympanostomy (Group B), and radiofrequency tympanostomy with topical mitomycin C application (Group C). One hundred twenty ears diagnosed as having otitis media with effusion were equally randomized to the last two procedures only. Patients were followed-up every week in the first month, every 2 weeks in the second month, and monthly after that until closure of the tympanostomy. A special follow-up setting was designed 3 months after tympanostomy closure where tympanograms and pure-tone audiograms were obtained. RESULTS Groups B and C showed a significantly slower rate of closure than Group A. At the same time, Group C demonstrated a slower rate when compared with Group B. The mean closure time of Group B was 3.5 weeks, with no difference between recurrent acute otitis media and otitis media with effusion. In contrast, the mean closure times for Group C were 5.3 and 7 weeks in cases of otitis media with effusion and recurrent acute otitis media, respectively, with the latter demonstrating a significantly slower closure rate. No recurrence of acute otitis media was reported in 10, 45, and 80% of Groups A, B, and C, respectively. Fifty-nine percent of Group C showed no clinical or tympanometric signs of otitis media with effusion 3 months after closure of tympanostomy. In contrast, Group B reported a lower cure rate (28%), with a statistically significant difference between both groups. Absence of recurrence and improvement in tympanometry signs correlated significantly with the duration of patency of tympanostomy (p < 0.01). The success rate was higher in patients who underwent adenoidectomy, but this did not reach statistical significance except in Group C (p < 0.01). CONCLUSION Radiofrequency and mitomycin C delay the closure rate of human tympanostomy. The efficacy of mitomycin C seems to be amplified in the presence of an inflamed tympanic membrane. Radiofrequency-assisted mitomycin-enhanced tympanostomy is a precise, safe, and cost-effective procedure that provides a viable approach in the management of recurrent acute otitis media and otitis media with effusion, especially when used in conjunction with adenoidectomy.

Abstract
OBJECTIVE To compare the efficacy of 5% NaHCO3, 3% H2O2, Sofradex (dexamethasone sodium metasulphobenzoate 0.05%, framycetin sulphate 0.5%, gramicidin 0.005%), 0.33% acetic acid and 0.9% NaCl eardrops in clearing grommets blocked with harvested thick middle ear effusion fluid. STUDY DESIGN A blinded in-vitro study. SETTING District general hospital. PARTICIPANTS A total of 473 grommets were blocked with freshly harvested unpooled thick middle ear effusion fluid obtained from 68 patients. MAIN OUTCOME MEASURES Patency of the grommets before and 7 days after intervention was ascertained by tympanometry and close visual inspection. RESULTS Instillation of eardrops leads to a statistically significant increase in the clearance of grommets as compared with not using any drops (chi2 = 14.3, d.f. = 5, P = 0.006). The numbers needed to treat were 2.8 for NaHCO3, 3.2 for 0.9% NaCl, 3.9 for 0.33% acetic Acid, 4.4 for Sofradex and 9.5 for H2O2 eardrops. Pair-wise comparison was only significant for comparison between 5% NaHCO3 and 3% H2O2 eardrops (Bonferroni corrected P = 0.01, odds ratio = 4.3, CI = 1.9-9.9). CONCLUSIONS Use of eardrops leads to a clinically and statistically significant increase in the clearance of blocked grommets. Of the five drops used, 5% NaHCO3 was the most efficacious and 3% H2O2 the least efficacious. Limitations of this in-vitro study are recognized and a prospective in-vivo double blind randomized controlled trial is planned.

Abstract
OBJECTIVE In children with acute otitis media (AOM), we compared clinical outcomes between groups with and without myringotomy to elucidate the effect of this procedure on long-term clinical course and prognosis. METHODS Fifty-nine children (29 male, 30 female) with tympanic membrane bulging or middle ear fluid (MEF) at initial presentation were assigned to one of two treatment groups. Group A received oral antibiotics and also underwent myringotomy at initial enrollment (36 cases), while group B received oral antibiotics without myringotomy (23 cases). Clinical outcomes were evaluated by otolaryngologic specialists using pneumatic otoscopy and tympanometry at 5, 10, 15, 30 days and 12 weeks and then every 2 weeks after the initial treatment. Otitis media with effusion (OME), early recurrence and recurrent AOM were used as the evaluation criteria for the prognosis. RESULTS In group A, 6 children (16.7%) showed transition to OME, 11 (30.6%) showed early recurrence of AOM, and 9 (25.0%) developed recurrent AOM. In group B 10, 8, and 3 (43.5%, 34.8%, and 13.0%) showed these respective adverse outcomes. While early recurrence rates and recurrent AOM rates did not differ significantly between groups, progression of OME was significantly less frequent in group A than group B (P = 0.036). CONCLUSIONS Lower rates of progression to OME in the group undergoing myringotomy suggested that myringotomy might be effective in preventing this outcome.

Abstract
In non-randomized clinical studies, the regression phenomenon can confound interpretation of the effectiveness of an intervention. The regression effect arises due to daily variation and/or misclassification of the biologic marker used in selection as well as in the assessment of the intervention effect. We consider a scenario in which the selection criterion for a subject's participation in the study is such that he/she must have a positive diagnostic test at screening. The disease status is then reassessed at the end of intervention. Thus, two repeated measurements of a binary disease outcome are available, with only selected subjects having a second measurement upon follow-up. We propose methods for estimating the change in event probability resulting from implementing the intervention while adjusting for the misclassification that produces the regression effect. We extend this approach to estimation of both the placebo and intervention effects in placebo-controlled studies designed with a misclassified binary outcome. Analyses of two biomedical studies are used for illustration.

Abstract
Otitis media with effusion (OME) is a common pediatric disease and there is great controversy concerning its management. Mechanical, medical and surgical treatments have not proven adequate in resolving the disease and serve mainly to manage complications. Leukotriene inhibitors are new drugs that have been approved recently for the treatment of asthma in children. The aim of this study was to evaluate the impact of leukotriene inhibitor therapy for asthma on the clinical course of OME in children with co-existing disease. Fifty children with bilateral OME and asthma, divided equally into two groups, were studied. The children in the first group were treated with budesonide and terbutaline inhalers together with the leukotriene inhibitor montelukast, whereas the children in the second group were treated with the inhalers alone. Duration of treatment was 30 days. Pneumatic otoscopy, tympanometry and pure-tone audiometry were performed at the beginning and at the end of treatment. Fifteen (60%) of the children receiving inhalers and montelukast and nine (36%) of those receiving only inhalers were found free of OME after 30 days of therapy. Thus, it may be concluded that a statistically significant beneficial effect on the clinical course of OME resulted from the addition of montelukast to the treatment of children with co-existing asthma and OME. Given that no medication has been shown to be effective in OME therapy, further investigation of the possible effects of leukotriene inhibitors is warranted.

Abstract
Otitis media with effusion in children: B-ENT Guidelines. OME is highly prevalent among young children, with peak prevalences at around two and five years of age. Although serious complications are rare, the burden of OM is large with impaired quality of life and high direct and indirect socio-economic costs. To date, medical treatment of OME is not recommended because of the limited scientific evidence that this treatment is effective in the long term. Surgical candidacy for OME depends largely on hearing status, associated symptoms, the child's developmental risk and the anticipated chance of spontaneous resolution of the effusion. Ultimately, the recommendation for surgery must be individualized.

Abstract
This article reviews the treatment of chronic sinusitis with macrolides. Chronic sinusitis is often the result of bacterial infections that lead to chronic inflammation with thickening of the sinus mucosa and hypersecretion of mucus. In addition to their anti-infective properties, some macrolides possess immunomodulatory effects. These macrolides have been used successfully to treat diffuse panbronchiolitis, a progressive inflammatory lung disease, and may be useful for treatment of asthma, chronic bronchitis, chronic sinusitis, cystic fibrosis, and bronchiectasis. The clinical benefits of macrolides in patients with chronic sinusitis include decreased nasal secretions and postnasal drip, with improvement in nasal obstruction. In vivo and in vitro studies show that some macrolides affect neutrophil chemotaxis and infiltration, inflammatory cytokine production, mucus production, and the transportability of airway secretions. These findings indicate that macrolides are promising agents for treating chronic inflammation of the airways.

Abstract
BACKGROUND The value of tympanometry in detection of middle ear effusion (MEE) has been widely studied in otitis media with effusion. There has been no direct comparison of tympanometric and tympanocentesis (TAP) findings in acute otitis media (AOM). We compared otoscopic, tympanometric and TAP findings in AOM including cases of AOM without effusion. METHODS In a study of AOM treatment of 90 children, a tympanogram was obtained, and TAP was performed before and after 5 days of treatment. Subjects were followed with otoscopy and tympanometry every 2 weeks for 3 months or until the MEE cleared. RESULTS In 130 AOM ears, otoscopic, tympanometric and TAP findings were available; MEE was obtained from 110 ears. Of 20 ears with a dry tap, 18 had abnormal tympanogram and otoscopic findings. With TAP findings as the standard, sensitivity and positive predictive value of type B tympanogram were 97 and 87%, respectively. Of 18 AOM ears yielding dry tap, 2 yielded MEE 5 days later, and 8 continued with evidence of MEE 5 days-12 weeks later. Five subjects with 8 AOM ears yielding dry tap were lost to follow-up; all had short duration of clinical symptoms. CONCLUSIONS Although otoscopic and tympanometric findings suggested the presence of MEE in AOM, MEE was unobtainable by TAP in 14% of cases. Dry tap cases likely represent early AOM before accumulation of detectable MEE. However, technical difficulty in obtaining small amounts of or highly viscous MEE could not be excluded. Sensitivity and positive predictive value of abnormal tympanograms in detection of MEE in AOM cases are comparable with those in otitis media with effusion.
