Tuberculous otitis media as a secondary infection to chronic otitis media with cholesteatoma.

A series of six cases of tuberculous otitis media is reviewed. All patients had a history of chronic otorrhea and were operated on with a presumptive diagnosis of chronic otitis media with cholesteatoma. Postoperatively the diagnosis of tuberculosis was established by histologic examination of the granulation tissue from the middle ear and mastoid. We believe that any patient with a long history of discharging ears needs histologic examination, as tuberculous otitis might be the cause of infection. We report our findings in these patients and discuss the possibility of penetration of tuberculous mycobacteria into the ear and mastoid. In our opinion, the tuberculosis is secondary to established ear infection.

Association of the FBXO11 gene with chronic otitis media with effusion and recurrent otitis media: the Minnesota COME/ROM Family Study.

OBJECTIVE: The FBXO11 gene is the human homologue of the gene mutated in the novel deaf mouse mutant jeff (Jf), a single gene model of otitis media. We have evaluated single nucleotide polymorphisms (SNPs) in the FBXO11 gene for association with chronic otitis media with effusion/recurrent otitis media (COME/ROM). DESIGN: A total of 13 SNPs were genotyped across the 98.7 kilobases of genomic DNA encompassing FBXO11. Data were analyzed for single SNP association using generalized estimating equations, and haplotypes were evaluated using Pedigree Disequilibrium Test methods. PATIENTS: The Minnesota COME/ROM Family Study, a group of 142 families (619 subjects) with multiple affected individuals with COME/ROM. MAIN OUTCOME MEASURES: Genetic association of COME/ROM with polymorphisms in FBXO11. RESULTS: The FBXO11 SNPs are contained in a single linkage disequilibrium haplotype block. Ten of the 13 SNPs were sufficiently polymorphic in the sample to permit analysis. In univariate genetic analysis, 1 reference SNP (hereinafter rs) (rs2134056) showed nominal evidence of association to COME/ROM (P = .02), and 2 SNPs approached significance (rs2020911, P = .06; rs3136367, P = .09). In multivariable analyses, including known risk factors for COME/ROM (sex, exposure to smoking, attending day care centers, no prior breastfeeding, and having allergies), the evidence of independent association was reduced for each SNP (eg, rs2134056, from P = .02 to P = .08). In subsequent analyses using the Pedigree Disequilibrium Test, the association of FBXO11 SNP rs2134056 (P = .06) with COME/ROM was confirmed. Incorporating multiple SNPs in 2- and 3-locus SNP haplotypes, those haplotypes containing rs2134056 also exhibited evidence of association of FBXO11 and COME/ROM (P values ranging from .03 to .10). CONCLUSION: We have observed evidence consistent with an association between polymorphisms in FBXO11, the human homologue of the Jeff mouse model gene, and COME/ROM.

Detection of Alloiococcus otitis in mixed bacterial populations from middle-ear effusions of patients with otitis media.

BACKGROUND: Otitis media is a potentially serious disorder, since there is a risk of permanent hearing loss. Culture methods are not useful in characterisation of populations of bacteria in the middle ear. We have used a PCR-based method that does not depend on prior knowledge of the bacteria identified by culture. METHODS: Middle-ear effusion fluid was obtained from 12 patients with chronic otitis media with effusion. Total DNA was extracted from the samples, and the hypervariable regions of bacterial 16S rRNA genes were amplified by means of broad-range PCR primers. Individual PCR products were segregated by cloning to allow analysis of mixed bacterial populations. FINDINGS: Many bacterial species were detected by PCR, whereas with culture-based approaches, no bacterial growth was detected for ten of the 12 patients. The gram-positive bacterium Alloiococcus otitis (A. otitidis) was detected by 16S rDNA amplification in six of the twelve samples, but not by culture techniques. Interpretation The method may have general usefulness in characterising bacterial populations at the site of infection and may indicate, from small sample numbers, organisms that are candidates for further investigation.

Children with recurrent episodes of acute otitis media: the effect of local administration of immunoglobulin G on acute otitis media, colonization and turnover of non-encapsulated Haemophilus influenzae in the nasopharynx.

In most children with recurrent episodes of acute otitis media (AOM), tube treatment is successful, but there are those who nevertheless suffer from middle ear infections. The aim of the present study was to ascertain whether local administration of immunoglobulin could reduce the number of episodes of otorrhoea in otitis-prone infants <2 years old who were treated with tubes, or whether it could affect the nasopharyngeal colonization and turnover of bacterial pathogens in the nasopharynx. IgG or placebo were also administered intranasally daily for 6 months to 50 infants, randomized in a double-blind study. An arbitrarily primed polymerase chain reaction (AP-PCR) was used to characterize the different isolates of NTHI (non-encapsulated, non-typable Haemophilus influenzae). Three infants in the IgG group and six infants in the control group suffered from > or =3 episodes of acute otitis media. No effect on the nasopharyngeal colonization or the turnover of non-encapsulated H. influenzae in the nasopharynx could be detected in either group.

C1q and C1 subcomponent complexes in otitis-prone and non-otitis-prone children. A prospective study of children during their first years of life.

Children with recurrent acute otitis media (rAOM) often show reduced C1q concentrations and an excess of (C1r-C1s)2 complexes. It is not known if such C1 aberrations precede development of rAOM or are a consequence of the infections. For this reason, serial investigation of C1q and C1 subcomponent complexes from birth until the age of three was performed in 113 children, 13 of whom developed rAOM. C1q concentrations at birth were found to be lower in the rAOM group than in children who did not experience acute otitis media, and were also correlated with age at the time of the first AOM episode. However, the wide variation of C1q within the groups precluded the use of C1q as a predictive marker. Excess (C1r-C1s)2 complexes were consistently absent at birth. High concentrations were found in children with established otitis media and the complexes persisted in association with recurrent disease. In conclusion, the C1 aberrations characteristic of rAOM were mainly acquired as a result of infection.

Medical treatment of chronic otitis media with effusion (secretory otitis media).

To determine whether antimicrobial therapy is of value in the treatment of chronic otitis media with effusion (secretory otitis media), we treated 1,429 4- to 8-year-old children--2224 affected ears--with a fixed regimen of an antibiotic mixture (Pediazole) for 10 days and a decongestant (Novafed) for 30 days. We observed the children monthly to determine the rate of clearance. Validity of diagnosis was greater than 90% with an algorithm of pneumatic otoscopy and tympanometry. Medication compliance was not measured. At 1 month, 45% of the children (48% of the ears) had cleared and at 2 months, 60% of the children (63% of the ears) had cleared. Factors such as sex and prior treatment in the preceding 3 months were no different in the cured vs. the uncured groups. Age significantly influenced the cure rate (P less than 0.0001); the older the child, the higher the clearance rate. Tympanograms type 5, 8, and 12-14 were significantly more prevalent in the uncleared group (P = 0.0001). The clear rate for unilateral cases was 76% and for bilateral cases, 47% (P less than 0.0001). Children with chronic otitis media with effusion are most likely to be cured by medical therapy/time if they are older, have unilateral disease, or a peaked tympanogram. Surgery should be withheld in these children for 2 or more months to permit the highest rate of spontaneous resolution.

Antibody activity before and after pneumococcal vaccination of otitis-prone and non-otitis-prone children.

The antibody activity of the IgM class and subclasses of IgG and IgA against pneumococcal bacteria of types 3, 6A and 19F was studied before and after administration of a pneumococcal vaccine (Pneumovax) in a group of children with recurrent acute otitis media (rAOM) and in groups of non-otitis-prone children. Only occasionally was there a significant rise in antibody activity after vaccination in any of the groups. There was no difference in the response to vaccination between rAOM children and healthy children. However, rAOM children exhibited lower antibody activities in most Ig subclasses against pneumococcus type 6A--a common causative agent in AOM--before as well as after vaccination compared with the healthy children. The results indicate that the response to vaccination is equally poor in all children, irrespective of whether they have a history of frequent attacks of acute otitis media, but, in contrast to healthy children, the rAOM children seem to have an inability to mobilize antibodies in response to infections with some pneumococcal types.

Secretory IgA-, IgG- and C3b-coated bacteria in the nasopharynx of otitis-prone and non-otitis-prone children.

The proportions of secretory IgA (SIgA)-, IgG- and C3b-coated bacteria obtained from a well-defined area on the posterior wall of the nasopharynx (NPH) close to the Eustachian tube were determined. Samples taken from 25 otitis-prone (OP) and 25 non-otitis-prone (NOP) children with normal serum levels of IgA and IgG were evaluated using an immunofluorescence assay. Both groups harboured significantly more nasopharyngeal bacteria coated with IgG than with SIgA (p < 0.001). The OP children had significantly fewer SIgA-coated bacteria (p < 0.05) but more C3b-coated bacteria (p < 0.01) in the NPH than the NOP children had. No significant difference was noted between the two groups regarding IgG coating. The occurrence of Branhamella catarrhalis in the NHP was more pronounced in the OP group (p < 0.05). No significant differences in the occurrence of other middle ear pathogens (Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus) or quantitative dominance of pathogens were noted between the two groups. Deficiency in SIgA coating of the nasopharyngeal bacteria may contribute to the otitis-prone condition.

Antimicrobial therapy for otitis media with effusion ('secretory' otitis media).

OBJECTIVE: To determine the effectiveness of antimicrobial treatment for otitis media with effusion ("secretory" otitis media) in children. DATA SOURCE: We report the reexamination of a previously published study by Mandel et al that evaluated the efficacy of a 2-week course of antimicrobials (amoxicillin trihydrate) with and without a 4-week course of an oral decongestant-antihistamine combination in a double-blind, placebo-controlled, randomized trial involving 518 infants and children with otitis media with effusion. DATA SYNTHESIS: At 4 weeks, amoxicillin efficacy as determined by a tympanometric criterion (P = .121) or by a measure of improvement in hearing (P = .311) was insignificant. Only by otoscopic judgment, which is shown to contain a systematic bias as used in this clinical trial, could an argument be made for a marginal efficacy of amoxicillin at the 4-week end point. Logistic regression analyses of the combined effects of treatment and prognostic factors showed no significant differences between placebo- and antibiotic-treated groups for unilateral effusions and for bilateral effusions. When subjects with unilateral and bilateral effusions were combined, the estimated efficacy of antibiotic treatment was 12.3% by otoscopy (P = .014) and 4.8% by tympanometry (P = .171). We also demonstrate the sensitivity of outcome to diagnostic measures used and provide statistical evidence questioning the validity of otoscopic observations in this study. Six weeks after the termination of amoxicillin therapy, the recurrence of effusion was two to six times higher in the amoxicillin-treated children than in those treated with placebo (P = .001), and resolution of effusion was not significantly different among antibiotic and placebo groups (13.6% and 11.3%, respectively; P = .477). CONCLUSIONS: Amoxicillin with and without decongestant-antihistamine combination is not effective for the treatment of persistent asymptomatic middle-ear effusions in infants and children.

[A severe form of external otitis: necrosing diabetic otitis].

Otitis externa are of usual observation in inter-tropical regions. Pseudomonas aeruginosa is responsible generally. But, when immunodeficiency is associated or on diabetic diathesis, such an otitis externa can be extremely dangerous: extensive osteitis of the base of the skull, paralysis of the last pairs of cervical nerves rapidly creeping, built a clinical identity called malignant external otitis, leading to death in 50% of the cases.

An alternative to regular dressings for otitis externa and chronic supperative otitis media?

Otitis externa and chronic otitis media often present to the otolaryngologist with a discharging ear. The conventional method of treatment is to perform regular aural toilet and insert medicated dressings into the external auditory canal. This treatment is either performed by trained nurses or medical staff, but in either case is time consuming. This study compares the efficacy of the above standard regimen with a novel treatment where a single aural toilet is carried out and medicated ointment instilled into the ear. Both regimens were evaluated at three weeks. Our results shows that there was no significant difference between the two treatment regimens with regard to the resolution of either of the conditions studied or the improvement in the symptom status of the patients. On the basis of this it would seem that a single aural toilet and instillation of medicated ointment is a valid treatment option, cuts down hospital attendance and could be performed in the community by general medical practitioners or trained practice nurses.

Relationship between acute suppurative otitis media and chronic secretory otitis media: role of antibiotics.

A total of 204 chronic middle ear effusions from 122 children have been studied. Bacteria were isolated from 30 effusions. The commonest species found were Strep. pneumoniae and H. influenzae. These are also the commonest organisms causing acute otitis media (AOM). A similar pattern of serotypes was also demonstrated. In vitro sensitivity testing showed that most of the organisms isolated were sensitive to most commonly-used antibiotics. The main exception was resistance to penicillin amongst strains of H. influenzae and Staph. aureus. It is suggested that some cases of chronic secretory otitis media (SOM) may arise as a result of incomplete resolution of AOM and that the use of penicillin to treat AOM may be one factor in this process.

Decongestants and antihistamines for acute otitis media in children.

BACKGROUND: Acute otitis media (AOM) is a common and important source of morbidity in children, although most cases resolve spontaneously. While frequently recommended, decongestant and antihistamine therapy is of unclear benefit. OBJECTIVES: To determine the efficacy of decongestant and antihistamine therapy in children with AOM on outcomes of AOM resolution, medication side effects, and complications of AOM. SEARCH STRATEGY: Comprehensive search of Cochrane's Controlled Trials Registry, Medline and Embase was conducted. Bibliographic review and requests for information from study authors and pharmaceutical companies supplemented this. SELECTION CRITERIA: Randomized controlled trials evaluating decongestant (DC) or antihistamine (AH) treatment for children with AOM were included. Patient-oriented outcomes were considered most relevant. There were no quality or language restrictions. DATA COLLECTION AND ANALYSIS: Investigators independently evaluated studies for inclusion, performed validity assessments, and completed data extraction. Dichotomous data were pooled to generate relative risks and numbers needed to treat, and homogeneity was assessed using approximate chi-square tests. MAIN RESULTS: For the combined control groups, healing rates at 2 weeks were high, with rates of persistent AOM <23%. No additional benefit was demonstrated from intervention subgroupings DC, AH, or any medication (DC and/or AH). Only the combined treatment (DC + AH) group demonstrated statistically lower rates of persistent AOM at the 2-week period (RR 0.76, 95% CI, NNT 10.5, 95% CI). No benefit was found for other outcomes including early or late cure rates, symptom resolution, prevention of surgery or other complications. There was an increased risk of medication side effects for those receiving an intervention, which reached statistical significance for the "any medication" and decongestant groupings (NNH 16.6, 14.3 respectively, 95% CI ). Validity subanalyses demonstrated that lower quality studies found benefit, but analysis of those studies with higher validity scores found no benefit to treatment. REVIEWER'S CONCLUSIONS: Given lack of benefit and increased risk of side effects, these data do not support the use of decongestant, antihistamine, or combined DC/AH treatment in children with AOM. The small statistical benefit found in the combination medication group is of small clinical significance and study design may be biasing the results.

Responses to rubella, tetanus, and diphtheria vaccines in otitis-prone and non-otitis-prone children.

Delayed immunologic maturation--among other things based on a selective lack of antibodies against some acute purulent otitis media (AOM)-associated pneumococcal types--has been proposed in children with recurrent AOM (rAOM). To further elucidate the immunologic response in these children, we compared the antibody responses to diphtheria, tetanus, and rubella vaccinations in 13 children with rAOM and 29 children without AOM. The children took part in a prospective study from birth to the age of 3 years. The antibody response to the rubella vaccine was significantly lower in the children with rAOM. The responses to tetanus and to diphtheria did not differ between children with and without rAOM. Thus, the results indicate that in addition to the known lack of antibodies against pneumococcal polysaccharide antigens, a lower antibody response against at least one protein antigen may exist in otitis-prone children.

[Hearing acuity in otitis media with effusion and adhesive otitis media].

The relationship between findings established by the photograph of the tympanic membrane and hypacusia was determined by pure-tone audiometry. Subjects were 352 ears of 267 patients diagnosed as otitis media with effusion (OME) or adhesive otitis media (AdOM). These two diseases were evaluated on the basis of photographs of the tympanic membrane taken from 1983 to 1988. The results were as follows; 1) The effect of aging process on hearing acuity was noted in patients with these diseases, i.e., values of hearing acuity by air and bone conduction were, in descending order, early-, mature-, and advanced-age groups, with significant differences (p less than 0.01). 2) Greater loss of acuity by air conduction in the middle to high frequency ranges was found in patients with OME than with AdOM. In bone conduction, a decrease in low frequency range in the early--and mature--age groups was larger in patients with AdOM than with OME and a significant decrease in 2000-6000 Hz in the advanced-age group was more marked in patients with OME than with AdOM (p less than 0.05). 3) Among patients with AdOM, those with retained fluid in the middle ear showed a significant decrease in air conduction values and a significant increase in air-bone gap compared with those without fluid (p less than 0.05). 4) The degrees of adhesion correlated well with a decrease in hearing acuity. 5) Hearing acuity was not influenced by attic retraction, white plaque, scar and atrophy of their tympanic membranes.

Cervical spinal tuberculosis with tuberculous otitis media masquerading as otitis externa malignans in an elderly diabetic patient: case report.

Extrapulmonary manifestation of tuberculosis (Tb), a medieval disease, occurs in every part of the body with varying degree of frequency but commonly in the pleural and lymph nodes. When it occurs in bones thoracolumbar vertebrae is the usual site of involvement. Other bones are less involved hence seldomly reported. This is true for other organs and parts of the body including larynx, pharynx nose and the middle ear. More importantly, isolated extrapulmonary tuberculosis without pulmonary involvement is uncommon. The case of a 65 year old Nigerian trader who presented with headache, chronic ear ache with otorrhoea, persistent neck pain and found to be diabetic on further evaluation is presented. She was hitherto managed as a case of otitis external malignans without any improvement but rather her clinical condition worsened with evidence of cervical vertebra destruction and multiple cranial nerve palsies without pulmonary tuberculosis. Prompt and effective response to anti tuberculosis drugs informed the diagnosis of tuberculosis of the cervical vertebra and tuberculous otitis media with multiple cranial nerve palsies. This case underscores the value of high index of suspicion, thorough and complete clinical evaluation in any patient with chronic symptoms and signs unresponsive to conventional treatment.

[Bacteriologic evaluation of otitis externa and chronic otitis media].

The authors present results of bacteriological examinations in 187 patients with chronic otitis media (OMC) and otitis externa treated in ENT Department, Medical University of Gdańsk in the years 1997-1998. Ear swabs and aspirates were investigated for aerobes and anaerobes 254 bacterial isolates were obtained. Among 150 patients with OMC aerobes were isolated in 130 (86.7%) in 13 (8.5%) mixed aero-anaerobes flore and in 20 (19.3%) no bacterial growth was observed. From patients with COM there were 199 bacterial isolates among them 177 aerobes cultures, 13 anaerobes and 9 fungal. From the external ear canal there were 55 cultures, among them 45 (81.8%) aerobes, 6 (10.9%) mixed aero-anerobes and 4 (7.3%) fungal. The most frequent observed bacteria were Staphylococcus aureus, Pseudomonas aeruginosa and Proteus mirabilis which showed the best susceptibility on ciprofloxacine and amikacine.

Secretory otitis media with malignant external otitis.

Secretory otitis media (SOM) was found in six out of 12 patients with malignant external otitis (MEO). The condition caused hearing loss and the otoscopy showed the usual SOM formation. The fluid disappeared through a recovery stage of air bubbles in the middle ear. It is suggested that SOM is caused by medial penetration of MEO, resulting in infection of the eustachian tube. CT scanning supports this hypothesis.
