Dr. Mary Fanning: caring for AIDS patients at Toronto General.

Although amoxicillin has long been the preferred drug for treatment of acute otitis media, resistant strains of two relatively common causal organisms have emerged, prompting a search for other antibiotics. We performed a randomized double-blind trial comparing amoxicillin and trimethoprim-sulfamethoxazole in 221 children in whom acute otitis media was diagnosed in an outpatient setting. Diagnosis was on the basis of symptoms, otoscopic examination and acoustic reflectometry. No culture specimens were taken. A research nurse, using the same methods, evaluated patients in a follow-up home visit at around 14 days and measured compliance by examination of the medicine bottle. Equal proportions of children in the two groups were cured or improved (88% and 87%). Therapeutic efficacy was related to compliance in both groups, and there were few side effects in either group. This study had statistical power of 80% to detect a difference of 15%. We conclude that trimethoprim-sulfamethoxazole can be considered a first-line antibiotic in the treatment of acute otitis media.

Effect of recolonisation with "interfering" alpha streptococci on recurrences of acute and secretory otitis media in children: randomised placebo controlled trial

ObjectiveTo study the effect of recolonisation with α streptococci with the ability to inhibit the growth of otopathogens (“interfering” activity) on the recurrence of acute otitis media in susceptible children and the effect on the frequency of secretory otitis media.DesignDouble blind, randomised, placebo controlled study.SettingEar, nose, and throat clinic with three doctors.Participants130 children prone to otitis media aged between 6 months and 6 years, 108 of whom were eligible and followed for 3 months.InterventionsChildren with no recurrences during the last month received phenoxymethylpenicillin (n=22), and those with a recurrence within 1 month received amoxicillin clavulanic acid (n=86), both twice daily for 10 days. These were followed by a streptococcal or placebo solution sprayed into the nose for a further 10 days. At day 60 the same spray was started for another 10 days.ResultsAt 3 months 22 children (42%) given the streptococcal spray were healthy and had a normal tympanic membrane compared with 12 (22%) of those given placebo. This difference was shown separately for recurrences of both acute otitis media and secretory otitis media.ConclusionsSelected bacteria with the ability to inhibit the growth of common otopathogens can be used to protect against recurrent acute otitis media and secretory otitis media in children.     

Diagnosis and antibiotic treatment of acute otitis media: report from International Primary Care Network.

STUDY OBJECTIVE--The relation between a history of disorders suggestive of acute otitis media, symptoms, and findings of an examination of the tympanic membrane and doctors'' certainty of diagnosis. Also, to examine differences in prescribing habits for acute otitis media among doctors from different countries. DESIGN--Questionnaires were completed by participating doctors for a maximum of 15 consecutive patients presenting with presumed acute otitis media. SETTING--General practices in Australia, Belgium, Great Britain, Israel, The Netherlands, New Zealand, Canada, Switzerland, and the United States. PATIENTS--3660 Children divided into the three age groups 0-12 months, 13-30 months, and greater than or equal to 31 months. MAIN OUTCOME MEASURES--General practitioners'' responses to questions on their diagnostic certainty and resolution of patients'' symptoms after two months. RESULTS--The diagnostic certainty in patients aged 0-12 months was 58.0%. This increased to 66.0% in those aged 13-30 months and 73.3% in those aged greater than or equal to 31 months. In all age groups diagnostic certainty was positively associated with the finding of a tympanic membrane that was discharging pus or bulging. Redness of the membrane and pain were also associated with certainty in patients aged 13-30 months, and a history of decreased hearing or recent upper respiratory infection was positively associated in patients aged greater than or equal to 31 months. The proportion of patients prescribed antibiotics varied greatly among the countries, from 31.2% in The Netherlands to 98.2% in both Australia and New Zealand, as did the duration of treatment. Patients who did not take antibiotics had a higher rate of recovery than those who did; the rate of recovery did not differ between different types of antibiotic. CONCLUSIONS--Doctors'' certainty of diagnosis of acute otitis media was linked to patient''s age. Improved criteria or techniques for diagnosing acute otitis media, especially in very young children, need to be developed. Antibiotic treatment did not improve the rate of recovery of patients in this study.

儿童腺样体肥大程度与分泌性中耳炎发生的相关性研究(英文)

目的:探讨儿童腺样体肥大程度与分泌性中耳炎发生及预后的相关性,指导临床医师对分泌性中耳炎作出早期诊断和治疗。方法:239例住院手术切除腺样体的儿童,常规行鼻咽侧位片、声导抗检查;部分伴耳部症状、声导抗显示C型曲线或查体可疑鼓室积液征者行颞骨CT检查或术中行鼓室穿刺。经统计学分析,比较分泌性中耳炎与腺样体肥大程度及咽鼓管咽口情况的相关性。结果:在239例腺样体肥大儿童中,经鼓室穿刺证实合并分泌性中耳炎者34例(63耳,14.2%),其中鼓室曲线呈B型者33耳(52.4%),C型(-200 dapa)者10耳(15.9%),C型(-200 dapa)者20耳(31.7%)。结果表明分泌性中耳炎的发生与腺样体肥大程度及咽鼓管园枕受压迫的程度呈正相关。结论:声导抗检查不能作为分泌性中耳炎诊断的金标准,必要时可行颞骨CT明确诊断;对腺样体肥大伴分泌性中耳炎的儿童鼻内镜下腺样体切除为其主要疗法,配合鼓室穿刺多可治愈,对反复发作的分泌性中耳炎行鼓室置管术,避免术后并发症的发生。     

Computed tomography in the diagnosis of exudative otitis media

Temporal bone computed tomography (CT) was used to examine 37 patients aged 2 to 55 years who had exudative otitis media; in 27 patients of them, a pathological process was bilateral. An analysis of 58 temporal bone CT scans identified the CT signs of chronic exudative otitis media. These included a partial or complete block of the osseous foramen of the auditory tube; impaired pneumatization of the tympanic cavity, mastoid process fenestrae, and antrum; pathological drawing-in of the tympanic membrane. The preservation of the auditory ossicles and the absence of destructive changes in the walls of the cavities of the middle ear were observed in most cases. Repeated temporal bone CT study was performed in 10 patients (14 temporal bones) in different periods (from 2 months to 3 years) after surgery. The results of tympanostomy were visually assessed. These included recovered pneumatization of middle ear cavities (7 temporal bones), a cicatricial process in the tympanic cavity (5 temporal bones), recurrence of the CT manifestations of exudative otitis media (2 temporal bones).

Potentialities of temporal bone computed tomography in the identification of causes of hypoacusis of postinflammatory genesis

Temporal bone computed tomography (CT) was used to examine 64 patients with impaired hearing due to inflammatory diseases of the middle year. In 21 patients, the pathological process was bilateral. A total of 85 series of temporal bone CT scans were analyzed. The patients' age ranged from 2 to 66 years. CT verified adhesive otitis media in 62 cases, otosclerosis in 7, local malformation of the auditory ossicles and/or the labyrinthine fenestrae in 11. No CT changes were revealed in 5 cases. The CT symptoms of adhesive otitis media were identified. These included soft tissue bands and/or soft tissue-density portions that fix the auditory ossicles or block the niches of the labyrinthine fenestrae (31 temporal bones); sclerosis or ossification of the ligaments and tendons of the middle ear (7 temporal bones); calcification foci in the tympanic cavity (9 cases); osteosclerotic changes in the epitympanus (2 cases); cicatricial changes in the tympanic membrane (24 cases); destructive changes in the auditory ossicles (19 temporal bones). There has been evidence that CT may be used for the differential diagnosis of adhesive otitis media from otosclerosis and congenital malformations of the structures of the middle ear.     

Co-amoxiclav in recurrent acute otitis media: placebo controlled study.

OBJECTIVE--To determine the efficacy of coamoxiclav in children aged 6 months to 12 years with recurrent acute otitis media. DESIGN--A randomised double blind placebo controlled clinical trial. SETTING--General practice in the Netherlands. PATIENTS--121 children with recurrent acute otitis media, defined by onset of otalgia and otoscopic signs of middle ear infection within four to 52 weeks after the previous attack. Confirmation of diagnosis and randomisation was done by otolaryngologists. INTERVENTION--Oral co-amoxiclav or placebo in weight related doses for seven days. MAIN OUTCOME MEASURE--An irregular clinical course defined as the presence of otalgia or a body temperature greater than or equal to 38 degrees C, or both, after three days. RESULTS--Eleven (16%; 95% confidence interval 9% to 28%) children had an irregular course in the co-amoxiclav group and 10 (19%; 9% to 31%) in the placebo group (difference not significant). Age, dichotomised at 2 years, was the only significant prognostic factor for irregular course of the disease (odds ratio 5.9; 1.8 to 19.1). Among children aged below 2 years, 28% (4/14) in the co-amoxiclav group and 58% (7/12) in the placebo group had irregular courses. For children 2 years and older these percentages were 13% (7/52) and 7% (3/41). CONCLUSION--Children with recurrent acute otitis media are at greater risk of an irregular clinical course of the disease than children with a first episode of acute otitis media. Co-amoxiclav has no significant benefit over placebo in treating children over 2 years with acute otitis media.     

The human otitis media with effusion: a numerical-based study

Otitis media is a group of inflammatory diseases of the middle ear. Acute otitis media and otitis media with effusion (OME) are its two main types of manifestation. Otitis media is common in children and can result in structural alterations in the middle ear which will lead to hearing losses. This work studies the effects of an OME on the sound transmission from the external auditory meatus to the inner ear. The finite element method was applied on the present biomechanical study. The numerical model used in this work was built based on the geometrical information obtained from The visible ear project. The present work explains the mechanisms by which the presence of fluid in the middle ear affects hearing by calculating the magnitude, phase and reduction of the normalized umbo velocity and also the magnitude and phase of the normalized stapes velocity. A sound pressure level of 90 dB SPL was applied at the tympanic membrane. The harmonic analysis was performed with the auditory frequency varying from 100 Hz to 10 kHz. A decrease in the response of the normalized umbo and stapes velocity as the tympanic cavity was filled with fluid was obtained. The decrease was more accentuated at the umbo.     

Role of Toll-like receptor 4 in innate immune responses in a mouse model of acute otitis media

Nontypeable Haemophilus influenzae (NTHi) is considered a major pathogen underlying middle ear infection. This study characterized the role of Toll-like receptor 4 in the innate immune responses to acute otitis media induced by NTHi in mice. We used C3H/HeJ mice, which have nonfunctional Toll-like receptor 4, and normal wild-type C3H/HeN mice. NTHi were injected into the tympanic bulla, and middle ear effusions and tissues were collected. In C3H/HeN mice, the severity of acute otitis media decreased promptly with a significant reduction in bacterial recovery from middle ear effusions 48 h after injection. In contrast, all C3H/HeJ mice had otitis media at all time points examined, and increasing bacterial counts from middle ear effusions were detected in C3H/HeJ mice 72 h after injection. Expression of intracellular adhesion molecule-1 by the middle ear mucosa paralleled the number of polymorphonuclear cells in the middle ear in both strains. The findings of transmission electron microscopy revealed that phagocytosis and phagosome maturation of polymorphonuclear cells was impaired in C3H/HeJ mice. Our findings indicate that Toll-like receptor 4 plays a part in the early accumulation and functional promotion of polymorphonuclear cells in the middle ear for eradicating NTHi infection.     

PROPER USE OF ANTIBIOTICS IN TREATMENT OF ACUTE OTITIS MEDIA

The problem of preventing loss of hearing following acute otitis media has been made more complex by the use of penicillin and other antibiotic agents which may apparently cure yet leave dangerous residual disease. The causes of loss of hearing must be recognized early if remedial treatment is to be effective. In children particularly, loss of hearing may go unnoticed for some time.Physicians who treat otitis media should feel the responsibility not only of bringing an acutely ill child back to health but of preserving the function of the hearing mechanism. Careful examination of the ear after apparent subsidence of infection is mandatory. It is of the utmost importance to be able to recognize the ear drum in its normal state and its various pathological states and to be alert to the early signs of changes associated with loss of hearing. Antibiotics should not be expected to do more than help combat the acute infection in otitis media. Adequate follow-up demands strong suspicion of residual pathologic process in the ear. The prevention of loss of hearing still requires knowledge of the established clinical facts and therapeutic procedures and the application of this knowledge to treatment of acute infections of the middle ear.     

Chronic Conductive Hearing Loss Leads to Cochlear Degeneration

Synapses between cochlear nerve terminals and hair cells are the most vulnerable elements in the inner ear in both noise-induced and age-related hearing loss, and this neuropathy is exacerbated in the absence of efferent feedback from the olivocochlear bundle. If age-related loss is dominated by a lifetime of exposure to environmental sounds, reduction of acoustic drive to the inner ear might improve cochlear preservation throughout life. To test this, we removed the tympanic membrane unilaterally in one group of young adult mice, removed the olivocochlear bundle in another group and compared their cochlear function and innervation to age-matched controls one year later. Results showed that tympanic membrane removal, and the associated threshold elevation, was counterproductive: cochlear efferent innervation was dramatically reduced, especially the lateral olivocochlear terminals to the inner hair cell area, and there was a corresponding reduction in the number of cochlear nerve synapses. This loss led to a decrease in the amplitude of the suprathreshold cochlear neural responses. Similar results were seen in two cases with conductive hearing loss due to chronic otitis media. Outer hair cell death was increased only in ears lacking medial olivocochlear innervation following olivocochlear bundle cuts. Results suggest the novel ideas that 1) the olivocochlear efferent pathway has a dramatic use-dependent plasticity even in the adult ear and 2) a component of the lingering auditory processing disorder seen in humans after persistent middle-ear infections is cochlear in origin.     

Classification of Different Tympanic Membrane Conditions Using Fused Deep Hypercolumn Features and Bidirectional LSTM

Objectives: Middle ear inflammatory diseases are global health problem that can have serious consequences such as hearing loss and speech disorders. The high cost of medical devices such as oto-endoscope and oto-microscope used by the specialists for the diagnosis of the disease prevents its widespread use. In addition, the decisions of otolaryngologists may differ due to the subjective visual examinations. For this reason, computer-aided middle ear disease diagnosis systems are needed to eliminate subjective diagnosis and high cost problems. To this aim, a hybrid deep learning approach was proposed for automatic recognition of different tympanic membrane conditions such as earwax plug, myringosclerosis, chronic otitis media and normal from the otoscopy images.Materials and methods: In this study we used public Ear Imagery dataset containing 880 otoscopy images. The proposed approach detects keypoints from the otoscopy images and following the obtained keypoint positions, extracts hypercolumn deep features from 5 different layers of the VGG 16 model. Classification of tympanic membrane conditions were realized by feeding the deep hypercolumn features to Bi-LSTM network in the form of non-time related data.Results: The performance of the proposed model was evaluated in three different color spaces as Red-Green-Blue (RGB), Hue-Saturation-Value (HSV) and Haematoxylin-Eosin-Diaminobenzidine (HED). The proposed model achieved acceptable results in all color spaces, moreover it showed a very successful performance in classifying tympanic membrane conditions especially in RGB space. Experimental studies showed that the proposed model achieved Acc of 99.06%, Sen of 98.13% and Spe of 99.38%.Conclusion: As a result, a robust model with high sensitivity was obtained for classification of tympanic membrane conditions and it was shown that Bi-LSTM network, which is generally used with time-related data, could also be used successfully with non-time related data for diagnosis of tympanic membrane conditions.
