    Full Text Available La otitis media aguda es una de las enfermedades infecciosas más comunes diagnosticadas en niños. Con respecto a su tratamiento, el uso de antibióticos sigue siendo controvertido. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos seis revisiones sistemáticas que en conjunto incluyen 18 estudios clínicos aleatorizados. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que los antibióticos disminuyen el dolor a las 48-72 horas y reducen el riesgo de perforación timpánica en niños con otitis media aguda, sin embargo no disminuyen el riesgo de recurrencia tardía y aumentan el riesgo de efectos adversos (rash, vómitos y diarrea.

    2013-05-01

    Acute otitis media is one of the most common infections in childhood and the options of therapy have been examined in numerous studies. Nevertheless, there are controversial opinions regarding the question whether antibiotic therapy makes sense. This is proved through the many different ways that the primary treatment of the middle ear infection is handled throughout the international community. This work gives an overview of the current knowledge and based on these results gives practical recommendations to assist with the diagnosis and treatment of the individual patients. PMID:23247747

  13. Identification of bacteria causing acute otitis media using Raman microspectroscopy

    Ayala, Oscar D.; Wakeman, Catherine A.; Skaar, Eric P.; Mahadevan-Jansen, Anita

    2016-03-01

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

  14. Xylitol Syrup for the Prevention of Acute Otitis Media

    Corwin, Michael J.; Vezina, Richard M.; Pelton, Steven I.; Feldman, Henry A.; Coyne-Beasley, Tamera; Mitchell, Allen A.

    2014-01-01

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

    Cayé-Thomasen, Per; Schmidt, Peter Thelin; Hermansson, Ann; Holst, Jens Juul; Thomsen, Jens

    2004-01-01

    OBJECTIVE: The neuropeptide substance P (SP) is an inducer of neurogenic inflammation and bone resorption in the middle ear. Resorption of the bone tissue structures surrounding the middle ear cavity is a distinct feature of the initial stage of acute otitis media (AOM), which may be due to nerve...... fiber release of SP. MATERIAL AND METHODS: To investigate possible release of SP in the middle ear mucosa during AOM, we used a well-established rat model of AOM caused by Streptococcus pneumoniae. Following tissue extraction on Days 1, 3 and 6 post-inoculation, the mucosal concentration of SP was...... measured using a radioimmunoassay. RESULTS: Compared to sham-inoculated control ears, the concentration of SP was significantly reduced on Day 1 and even further reduced on Day 3, whereas partial replenishment was found on Day 6. CONCLUSION: SP seems to be depleted in the rat middle ear mucosa in the...

  19. Chronic silent otitis media.

    Paparella, Michael M; Schachern, Patricia A; Cureoglu, Sebahattin

    2002-01-01

    Otitis media occurs along a continuum. For example, otitis media with effusion characterized by fluid pathology can lead to chronic otitis media plus chronic mastoiditis, characterized by the presence of intractable tissue pathology such as cholesteatoma, cholesterol granuloma or granulation tissue. The literature defines chronic otitis media as having a tympanic membrane perforation and otorrhea. Amongst many other sequelae, which can result from the continuum, an important common one is chronic silent otitis media. This overlooked entity which includes pathology beneath an intact tympanic membrane is commonly seen in our human temporal bone laboratory and in patients. The clinical pathological correlates of this important disease are discussed herein. PMID:12021496

    Full Text Available Objective. This study uses the acute otitis media clinical practice guideline proposed in 2004 as a reference to evaluate whether antibiotics doses that are in line with the recommendations lead to better prognosis. The study also attempts to clarify possible factors that influence the outcome. Study Design. Retrospective cohort study. Subjects and Methods. A total of 400 children with acute otitis media were enrolled. The dosage of amoxicillin was considered to be appropriate when in accord with clinical practice guidelines, that is, 80–90 mg/kg/day. The outcome was defined according to the description of tympanic membrane on medical records. Multivariate logistic regression was used to analyze the relationship between antibiotic dosage and prognosis after adjusting for baseline factors. Results. The majority of prescriptions were under dosage (89.1% but it was not noticeably associated with outcome (P= 0.41. The correlation between under dosage and poor prognosis was significant in children below 20 kg with bilateral acute otitis media (odds ratio 1.63; 95% CI 1.02–2.59, P=0.04. Conclusion. Treating acute otitis media in children, high-dose amoxicillin with clavulanate as recommended in the clinical practice guideline was superior to conventional doses only in children under 20 kg with bilateral diseases.

    Marchisio, P; Santagati, M; Scillato, M; Baggi, E; Fattizzo, M; Rosazza, C; Stefani, S; Esposito, S; Principi, N

    2015-12-01

    This paper reports the results of the first study in which Streptococcus salivarius 24SMB, a safe α-haemolytic strain capable of producing bacteriocin-like substances with significant activity against acute otitis media (AOM) pathogens, was intranasally administered in an attempt to reduce the risk of new episodes of AOM in otitis-prone children. In this prospective, randomized, double-blind, placebo-controlled study, 100 children aged 1-5 years with histories of recurrent AOM were randomized 1:1 to receive an intranasal S. salivarius 24SMB or placebo twice daily for 5 days each month for 3 consecutive months. Fifty treated children and 47 who received placebo who were compliant with study protocol were followed monthly for 6 months. The number of children who did not experience any AOM was higher among the children treated with the S. salivarius 24SMB preparation than among those in the placebo group (30.0 vs 14.9%; p = 0.076). Moreover, the number of children who received antibiotics during the study period was lower among the children treated with S. salivarius 24 SMB than among those who received placebo (70 vs 83.0%; p = 0.13). Compared with the children who were not colonized by S. salivarius 24SMB after treatment, the number of colonized children who experienced any AOM was significantly lower (42.8 vs 13.6%; p = 0.03). Similar results were observed when the children treated with antibiotics for AOM were analysed (67.8 vs 95.5%; p = 0.029). This study revealed the ability of intranasally administered S. salivarius 24SMB to reduce the risk of AOM in otitis-prone children. PMID:26385346

    Gotsadze, K; Gogatishvili, R

    2005-05-01

    Acute otitis media is one of the most common diseases in childhood and adolescence. Its incorrect and non-rational treatment increases the frequency of complicated acute forms of the disease. Objective of the study was to define effectiveness of mucoregulatory medication (namely Sinupret produced by Bionorica A.G. Germany) for treatment of complicated forms of AOM along with antibiotics in children. The trial has been conducted at Tbilisi M. Guramishvili Pediatric Clinic. It represented a randomized controlled trial of two prescribing strategies for acute otitis media. The participants have been 64 children with AOM-preperforation stage. Among them 32 patients (study group) got oral antibiotics--Amoxicillin along with the mucoregulatory remedy (Sinupret) and the rest 32 patients (control group) received Amoxicillin orally (Amoxicillin was used 40-45 mg/kg/24 h in children and 1,5-3 g/24 h in adults) divided in three administrations. The clinical effect of treatment was assessed according to the following data: subjectively-complaints of patients; objectively-clinical examination data (otoscopy), blood test data; tympanometric data. Measurements have been conducted at the beginning of treatment, on the third, seventh days, at the end of the course of treatment and two weeks later. Subjectively patients complained about unbearable pains in the ear, anxiety, abrupt reduction of hearing, murmurs in the ears acquiring pulsative nature, high temperature. For the treatment of complicated forms of acute otitis media (III stage) mucoregulatory remedies in combination with antibiotics were quite effective. It reduces necessity of paracentesys; increases the efficiency of accompanying antibiotic therapy and reduces frequency of complications. PMID:15988076

  13. Multiple Complications Due to Subacute Suppurative Otitis Media

    Xhevair Hoxhallari

    2012-06-01

    Full Text Available Subacute otitis media is a well-known pathology of ENT practice which is easily diagnosed and subsequently treated in the outpatient clinic. The rate of complications in acute otitis media is lower than in chronic otitis media. We present here the history of a young patient with subacute otitis media who developed both localized labyrinthitis and facial palsy requiring surgical treatment. We conclude that the treatment of subacute otitis media should be carefully monitored because complications may occur. Surgical treatment and pressure release can be efficient for the treatment of a peripheral facial palsy in the course of acute or subacute otitis media.

  15. Literature review: use of xylitol for prevention of acute otitis media

    Pereira, Agnes de Fátima Faustino

    2009-03-01

    Full Text Available Introduction: Xylitol is a sugar naturally found in various vegetables and fruits. Studies have demonstrated that the xylitol can be used as new preventive method for acute otitis media (AOM. Objective: To clarify the possible mechanisms of xylitol actions to inhibit the growth of otopathogenic bacteria and to describe researches that contribute for the discussion about the feasibility of the use of this sugar in the prevention of AOM. Method: Literature review based on scientific articles selected by means of the medical databases: MEDLINE, Cochrane, PubMed (MeSH and Web of Science. Results: Studies have demonstrated the efficacy of xylitol to prevent the AOM, when it is administered five times a day in chewing gum. However, this sugar is not so effective in the prevention of AOM during upper airways infections. Final Comments: Xylitol seems to be an effective strategy in prevention of acute otitis media. However, new studies are necessary to establish ideal doses, frequencies and vehicles for the correct administration of the sugar, which allows for its utilization in the public health system.

  20. Homeopathic Ear Drops as an Adjunct in Reducing Antibiotic Usage in Children With Acute Otitis Media

    Jacobs, Jennifer

    2014-01-01

    Objective. To determine if use of a homeopathic ear drop preparation reduces antibiotic use in children diagnosed with acute otitis media (AOM). Methods. Children 6 months to 11 years old, diagnosed with AOM and managed with a delayed antibiotic approach, were randomized to standard therapy alone or standard therapy plus a homeopathic ear drop preparation. The primary outcome was whether or not the antibiotic prescription given at the index visit was filled during a 12- to 15-day follow-up period. Results. Among 210 enrolled children, follow-up antibiotic data were collected on 206. During the 12- to 15-day follow-up period, fewer parents of children randomized to the homeopathic ear drops group filled the antibiotic prescription compared with those of children receiving standard therapy alone (26.9% and 41.2%, respectively, P = .032). Conclusion. Homeopathic ear drops may be effective in reducing the use of antibiotics in children with AOM managed with a delayed antibiotic approach.

    2009-04-01

    After our recent discovery of a Streptococcus pneumoniae 19A "superbug" (Legacy strain) that is resistant to all Food and Drug Administration-approved antimicrobial drugs for treatment of acute otitis media (AOM) in children, other S. pneumoniae isolates from children with AOM were characterized by multilocus sequence typing (MLST). Among 40 isolates studied, 16 (40%) were serotype 19A, and 9 (23%) were resistant to multiple antimicrobial drugs. Two others had unreported sequence types (STs) that expressed the 19A capsule, and 8 (88%) of the 9 multidrug-resistant strains were serotype 19A, including the Legacy strain with the new ST-2722. In genetic relatedness, ST-2722 belonged to a cluster of reported strains of S. pneumoniae in which all strains had 6 of the same alleles as ST-156. The multidrug-resistant strains related to ST-156 expressed different capsular serotypes: 9V, 14, 11A, 15C, and 19F. PMID:19331730

  2. Sinusitis with eosinophilic otitis media

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

  3. Otitis media with effusion.

    2004-05-01

    The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline "Otitis Media With Effusion in Young Children," which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children 1 to 3 years old with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology-Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced-practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media. The subcommittee made recommendations that clinicians should 1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME, 2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk, and 3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known) or diagnosis (if onset is unknown). The subcommittee also made recommendations that 4) hearing testing be conducted when OME persists for 3 months or longer or at any time that language delay, learning problems

    Full Text Available In a period of 12 months 241 children (2-12 years old with Otitis Media were examined. 98 bacteria were isolated from Otitis Media discharge and tested for sensitivity against 13 generic antibiotics. The disk-agar diffusion and macrodilution both methods were used for these tests. Staphylococcus aureus had the highest and streptococcus pneumonia the lowest rate of occurrence. Otitis Media cases caused by merely a single bacterium were 12 fold more than those caused by two bacteria and 4 fold more than those caused by more than two bacteria. The antibacterial efficacy of carbenicillin, gentamicin, kanamycin and amikacin was higher than that of other antibiotics in disk-agar diffusion method. The MIC rates of cefoperazone against four most frequently encountered bacteria were higher than that of Mezlocillin.

    A randomized double-blind trial with a 7-valent pneumococcal conjugate vaccine was conducted in The Netherlands among 383 children, aged 1 to 7 years, with a history of recurrent acute otitis media. No effect of vaccination on the pneumococcal colonization rate was found. However, a shift in serotype distribution was clearly observed (R. Veenhoven et al., Lancet 361:2189-2195, 2003). We investigated the molecular epidemiology of 921 pneumococcal isolates retrieved from both the pneumococcal v...

  7. beta-lactamase-producing nontypeable Haemophilus influenzae fails to protect Streptococcus pneumoniae from amoxicillin during experimental acute otitis media

    Westman, E.; Lundin, S.; Hermansson, Ann; Melhus, Åsa

    2004-01-01

    Acute otitis media (AOM) is the most common reason for outpatient antimicrobial therapy. Mixed infections pose a potential problem, since the first-line drug used for the treatment of AOM, amoxicillin, can be neutralized by ß-lactamase-producing pathogens of the upper respiratory tract. To study the effects of a 5-day course of amoxicillin on a mixed middle ear infection, rats were challenged with Streptococcus pneumoniae alone or in combination with ß-lactamase-producing nontypeable Haemophi...

  11. Divergent mucosal and systemic responses in children in response to acute otitis media.

    Verhoeven, D; Pichichero, M E

    2014-10-01

    Acute otitis media (AOM), induced by respiratory bacteria, is a significant cause of children seeking medical attention worldwide. Some children are highly prone to AOMs, suffering three to four recurrent infections per year (prone). We previously determined that this population of children could have diminished anti-bacterial immune responses in peripheral blood that could fail to limit bacterial colonization in the nasopharynx (NP). Here, we examined local NP and middle ear (ME) responses and compared them to peripheral blood to examine whether the mucosa responses were similar to the peripheral blood responses. Moreover, we examined differences in effector cytokine responses between these two populations in the NP, ME and blood compartments at the onset of an AOM caused by either Streptococcus pneumoniae or non-typeable Haemophilus influenzae. We found that plasma effector cytokines patterned antigen-recall responses of CD4 T cells, with lower responses detected in prone children. ME cytokine levels did not mirror blood, but were more similar to the NP. Interferon (IFN)-γ and interleukin (IL)-17 in the NP were similar in prone and non-prone children, while IL-2 production was higher in prone children. The immune responses diverged in the mucosal and blood compartments at the onset of a bacterial ME infection, thus highlighting differences between local and systemic immune responses that could co-ordinate anti-bacterial immune responses in young children.

    Park, Moo Kyun; Lee, Byung Don

    2013-01-01

    Otitis media is defined as inflammation of the middle ear, including the auditory ossicles and the Eustachian tube. Otitis media is a major health problem in many societies. The causes of otitis media includes infection and anatomic/physiologic, host, and environmental factors. In general, otitis media is a childhood disease, and anatomic and physiologic changes have great effects on its development. Thus, in vitro or human experimental studies of otitis media are difficult. Several experimen...

  13. Trends in antibiotic treatment of acute otitis media and treatment failure in children, 2000-2011.

    Leah J McGrath

    Full Text Available OBJECTIVES: Guidelines to treat acute otitis media (AOM were published in 2004. Initial declines in prescribing were shown, but it's unknown if they were sustained. We examine trends in antibiotic dispensing patterns to treat AOM among a large population of children. We also document trends in antibiotic failure. STUDY DESIGN: Children aged 3 months to 12 years with an AOM diagnosis, enrolled in a commercial claims database between January 1, 2000-December 31, 2011 were included. Pharmacy claims within 7 days of diagnosis were searched for antibiotic prescriptions. Antibiotic failure was defined as a dispensing of a different antibiotic class within 2-18 days after the first prescription. We analyzed trends in antibiotic use and failure by class of antibiotic and year. RESULTS: We identified over 4 million children under 13 years with AOM. The proportion of antibiotic dispensing decreased from 66.0% in 2005 to 51.9% in 2007, after which the instances of dispensing rebounded to pre-guideline levels. However, levels began decreasing again in 2010 and the antibiotic use rate in 2011 was 57.6%. Cephalosporin prescriptions increased by 41.5% over eleven years. Antibiotic failure decreased slightly, and macrolides had the lowest proportion of failures, while all other classes had failure rates around 10%. CONCLUSIONS: In recent years, antibiotic dispensing to treat AOM remains high. In addition, the use of broad-spectrum antibiotics is increasing despite having a high rate of treatment failure. Overprescribing of antibiotics and use of non-penicillin therapy for AOM treatment could lead to the development of antibiotic-resistant infections.

    AIM: To determine parental knowledge about acute otitis media (AOM) and its antibiotic therapy, antibiotic resistance and the willingness to comply with the watchful waiting (WW) approach in primary care settings in southern Israel. METHODS: The study was conducted in 3 primary care clinics and the pediatric emergency room of Soroka University Medical Center. Questionnaires (20 questions on education background, previous AOM experience, knowledge on antimicrobial resistance and attitude vs the WW approach) were filled by 600 parents (150 at each centers) of children < 6 years of age. RESULTS: Mothers represented 69% of parents; 2% had an education of < 10 school years, 46% had high-school education and 17% had an academic degree. 69% parents reported previous experience with AOM and 56% thought that antibiotics represent the only treatment for AOM. Knowledge on bacterial resistance to antibiotics was reported by 57% of the parents; 86% parents were willing to accept/probably accept the WW approach for their children. Logistic regression analysis revealed a significant association between parental education and knowledge about bacterial resistance to antibiotics and that previous experience with AOM was significantly associated with reluctance to accept the WW approach. More parents with knowledge on bacterial resistance were willing to accept the WW approach compared with parents without such knowledge. No correlation was found between the education level and willingness to accept the WW approach. CONCLUSION: A significant correlation was found between previous parental education and experience with AOM and the knowledge about antibiotic use, bacterial resistance and acceptance of the WW approach.

    Acute otitis media (AOM) is an inflammatory response to microbes in the middle ear, sometimes associated with rupture of the tympanic membrane. Human leukocytes produce different patterns of inflammatory mediators in vitro when stimulated with Gram-positive and Gram-negative bacteria, respectively. Here, we investigated the cytokine and prostaglandin E2 (PGE2) responses in middle ear fluids (MEFs) from children with spontaneously perforated AOM, and related the mediator levels to the presence of pathogens detected by culture (live) or PCR (live or dead). Furthermore, the in vivo cytokine pattern was compared with that induced in leukocytes stimulated by dead bacteria in vitro. MEFs with culturable pathogenic bacteria contained more interleukin (IL)-1β (median: 110 μg/L vs. <7.5 μg/L), tumour necrosis factor (TNF) (6.3 μg/L vs. <2.5 μg/L), IL-8 (410 μg/L vs. 38 μg/L) and IL-10 (0.48 μg/L vs. <0.30 μg/L) than culture-negative fluids, irrespective of PCR findings. IL-6 and PGE2 were equally abundant (69-110 μg/L) in effusions with live, dead or undetectable bacteria. Cytokine levels were unrelated to bacterial species and to the presence or absence of virus. Similar levels of TNF and IL-6 as found in the MEFs were obtained by in vitro stimulation of leukocytes, whereas 11 times more IL-1β and 3.5 times more IL-8 were produced in vivo, and 22 times more IL-10 was produced in vitro. Vigorous production of proinflammatory cytokines accompanies AOM with membrane rupture, regardless of the causative agent, but the production seems to cease rapidly once the bacteria are killed and fragmented. IL-6 and PGE2, however, remain after bacterial disintegration, and may play a role in the resolution phase. PMID:19832705

  16. How to compare the efficacy of conjugate vaccines to prevent acute otitis media?

    De Wals, Philippe; Erickson, Lonny; Poirier, Béatrice; Pépin, Jacques; Pichichero, Michael E

    2009-05-11

    Although the currently available 7-valent pneumococcal conjugate vaccine (PCV7-CRM(197)) has been primarily designed for the prevention of invasive pneumococcal disease, it has also demonstrated the potential to prevent acute otitis media (AOM) and its associated complications. A candidate 11-valent pneumococcal conjugate vaccine (PCV11-HiD), which utilizes Haemophilus influenzae (Hi)-derived protein D as a carrier has demonstrated the ability to prevent AOM caused by not only vaccine serotypes of Streptococcus pneumoniae (Sp), but also those caused by Hi. The methodological, clinical, and epidemiological factors influencing results of vaccine trials for AOM prevention were reviewed and a model-based approach was developed, in order to assess the relative efficacy of different vaccine formulations. Six randomized trials having AOM as a measured outcome were identified. Vaccine efficacy (VE) ranged from -1% to 34% for all-cause AOM and between 56% and 64% for AOM caused by vaccine-type Sp. Using otopathogen-specific VE rates from the FinOM and POET trials and otopathogen distributions observed in three relatively unbiased studies, VE against all-cause AOM episodes under different scenarios was modeled. The most important factor explaining variation in VE estimates was bacterial replacement, which was present in the PCV7-CRM(197) FinOM study but not in the PCV11-HiD POET study. Another contributing factor was increased protection conferred against Hi AOM by protein D. Geographical variation in the distribution of otopathogens was a third factor explaining differences between trials. More studies on the current aetiology of AOM need to be performed to accurately predict the marginal benefit of a switch from PCV7-CRM(197) to the newly licensed PCV10-HiD-DiT or to the future PCV13-CRM(197).

  20. Blocking macrophage migration inhibitory factor activity alleviates mouse acute otitis media in vivo.

    Zhang, Jin; Xu, Min; Zheng, Qingyin; Zhang, Yan; Ma, Weijun; Zhang, Zhaoqiang

    2014-11-01

    This study was to investigate the role of macrophage migration inhibitory factor (MIF) in mouse acute otitis media (AOM), we hypothesize that blocking MIF activity will relieve mouse AOM. A mouse AOM model was constructed by injecting lipopolysaccharide (LPS) into the middle ear of C57BL/6 mice through the tympanic membrane (TM). MIF levels were measured by real-time PCR (RT-PCR) and ELISA after LPS application. Normal or AOM mice were given PBS or ISO-1 (MIF antagonist) every day for 10 days and the hearing levels were determined by measuring auditory brainstem response (ABR) threshold. After the ABR test finished, H&E staining was conducted and the inflammation was also measured by detecting interleukin (IL)-1β, tumor necrosis factor (TNF)-α and vascular endothelial growth factor (VEGF) levels with RT-PCR and ELISA. TLR-4 expression was determined by western blotting and NF-κB activation was determined by electrophoretic mobility shift assays. Compared with the normal control, MIF levels in the middle ear of LPS-induced AOM mice were significant increased. The ABR results showed that mean ABR thresholds in ISO-1 treated AOM mice were significantly reduced compared with PBS treated AOM mice since day 7, indicating that ISO-1 treatment potentially improved the hearing levels of AOM mice. H&E staining showed that ISO-1 treatment could reduce the mucosal thickness of AOM mice. In ISO-1 treated mice, TLR-4 expression and levels of IL-1β, TNF-α and VEGF were significantly lower compared with PBS treated AOM mice. ISO-1 treatment also significantly inhibited NF-κB activation in AOM mice compared with PBS treated AOM mice. These results suggested that blocking the activity of MIF by ISO-1 could reduce the inflammation in AOM mice in which process TLR-4 and NF-κB were involved. The reduction in MIF activity is conducive to alleviate mouse AOM, which may serve as a potential therapeutic target for the treatment of AOM. PMID:25108100

  1. Genetics of otitis media.

    Post, J Christopher

    2011-01-01

    There is a growing body of evidence, both from animal and human studies, that host genetic factors can influence the risk of developing otitis media (OM). The role of genetics in OM has been elucidated through studies with monozygotic and dizygotic twins, analyses linking genetic polymorphisms to OM susceptibility, and genome scans. Several twin studies have shown a strong genetic component to middle ear effusion risk, with the estimate of the role of heredity for the proportion of time with middle ear effusions being around 0.7. Genetic polymorphisms in plasminogen activator inhibitor-1, interleukin-6, tumor necrosis factor-α, human leukocyte antigen, and mannose-binding lectin have been variously linked with OM and upper respiratory infection susceptibility. Several genome linkage studies have identified chromosomal regions associated with chronic OM, including 3p, 10q, 10q22.3, 17q12 and 19q. A number of candidate genes are associated with these sites. Given the current state of understanding of the role of genetics in OM, a family history of OM should be ascertained for all patients. Children with a strong family history of OM should be considered as candidates for a more aggressive early treatment of OM, particularly if other risk factors are present. These children may be earlier candidates for the placement of tympanostomy tubes and/or adenoidectomy. Existing data do not support routine genetic testing to determine a child's susceptibility to OM; however, given the advances in whole genome sequencing, such testing may someday play a role in the management of the OM patient.

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

    Full Text Available Introduction. Acute otitis is one of the most common pediatric infectious diseases that requires an accurate diagnosis in order to direct appropriate therapy to reduce the risk of complications. In this study pathogens collected from pediatric patients and their antibiotic susceptibility patterns were evaluated. Methods. Between May 2009 and May 2010, 739 samples (swabs taken from nasopharynx in case of acute otitis media and/or from ears in case of acute external otitis, collected from 680 patients, suffering of otalgia, admitted to the emergency department of our Hospital were studied.The specimens were submitted for routine bacterial cultures and the susceptibility tests were performed according to Clinical Laboratory Standards. Nitrocefin was used to detect ß-lactamase activity. Results. 316 samples (42.8% of 739 were negative, 102 (13.8% were positive for Streptococcus pneumoniae, 97 (13.1% for Moraxella catarrhalis, 68 (9.2% for Haemophilus influenzae, 62 (8.4% for Pseudomonas aeruginosa, 49 (6.6% for Staphylococcus aureus, 36 (4.9% for Streptococcus pyogenes, 5 (0.7% for Gram negative and 4 (0.5% for Candida spp. Antibiotic susceptibility tests showed that amikacin, ceftazidime, ciprofloxacin, imipenem, meropenem and piperacillin/tazobactam were active against all Gram negative strains isolated.We found one strain of MRSA. Of 102 Streptococcus pneumoniae, 5 (4.9% were penicillin resistant and 25 (24.5% were erythromycin resistant, showing the prevalence of constitutive phenotype (80%. All M. catarrhalis strains were ß-lactamase producers while all H. influenzae were ß-lactamase negatives. Conclusions. The prevalent etiological agents in pediatric acute otitis are S. pneumoniae, M. catharralis, and H. influenzae, as reported in literature. In external acute otitis P. aeruginosa prevails in particular in summer.

    Through alterations primarily in the penicillin-binding proteins, a non-beta-lactamase-mediated resistance to beta-lactams has evolved in Haemophilus influenzae. The virulence of these chromosomally changed strains has been questioned. To ascertain whether these alterations involve a reduction in virulence of H. influenzae and whether they could be advantageous for the bacterium during amoxicillin treatment of acute otitis media, a total of 70 Sprague-Dawley rats were challenged with a suscep...

  7. The Effect of Acute Otitis Media on Transient Otoacoustic Emissions A Clinical Guide to Successful Treatment Course

    A. Bayat

    Full Text Available Introduction & Objective: Acute otitis media (AOM is the most common causes of acquired hearing loss in children with increasing incidence. In young children the diagnosis is restricted to otoscopy and tympanometry whereas evaluation of the auditory function is impossible due to noncompliance during pure tone audiometry. For this purpose, measurement of otoacoustic emissions, especially transient evoked ones (TEOAEs, can be applied. The aim of this study was to evaluate the effect of AOM on TEOAEs in young children before and after treatment course.Material & Methods: In an analytic, cross-sectional design, 42 young children with AOM, both sexes, aged 2 to 4.5 years were evaluated through tympanometry and transient otoacoustic emissions (TEOAEs. TEOAEs signal to noise ratio (SNR and reproducibility of AOM patients were compared before, two weeks and six weeks after the treatment course. Then AOM responses were compared with an age-matched control group. The results were analyzed using SPSS 16.Results: Our findings revealed that TEOAE parameters in AOM subjects were the most affected on highest frequencies. Significant changes of TEOAE parameters were found 2 weeks after the treatment with further improvement 6 weeks after the treatment course (P 0.05.Conclusion: The results of this study suggest that there was an improvement in TEOAE SNR and band reproducibility in serial TEOAEs measurements. Thus,application of TEOAEs is a beneficial method to follow up medical treatment in young children with AOM. (Sci J Hamadan Univ Med Sci 2011;18(3:17-21

    Levels of cytokines, interleukin (IL)-1 alpha, IL-1 beta, tumor necrosis factor (TNF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) were investigated in samples of the middle ear effusions (MEEs) from 144 ears with otitis media with effusion (OME) by enzyme-linked immunosorbent assay, followed by cytologic analysis. Middle ear effusions of the acute purulent type contained a significantly higher concentration of cytokines compared with normal control sera (p chronic stage of MEE showed higher levels of TNF than IL-1 and GM-CSF. Meanwhile, IL-1 beta showed significantly higher concentrations in acute purulent types than in serous and mucoid types (p otitis media but also with chronic otitis media. This study showed that cytokines, especially IL-1 beta, contribute to infiltration into the middle ear by inflammatory cells. This implies that the persistent presence of cytokines in MEE could be a factor in prolonged OME. PMID:1416648

  9. Otitis media: the chinchilla model.

    Giebink, G S

    1999-01-01

    Streptococcus pneumoniae infection and disease have been modeled in several animal species including infant and adult mice, infant and adult rats, infant Rhesus monkeys, and adolescent and adult chinchillas. Most are models of sepsis arising from intravenous or intraperitoneal inoculation of bacteria, and a few were designed to study disease arising from intranasal infection. Chinchillas provide the only animal model of middle ear pneumococcal infection in which the disease can be produced by very small inocula injected into the middle ear (ME) or intranasally, and in which the disease remains localized to the ME in most cases. This model, developed at the University of Minnesota in 1975, has been used to study pneumococcal pathogenesis at a mucosal site, immunogenicity and efficacy of pneumococcal capsular polysaccharide (PS) vaccine antigens, and the kinetics and efficacy of antimicrobial drugs. Pathogenesis experiments in the chinchilla model have revealed variation in ME virulence among different pneumococcal serotypes, enhancement of ME infection during concurrent intranasal influenza A virus infections, and natural resolution of pneumococcal otitis media (OM) without intervention. Research has explored the relative contribution of pneumococcal and host products to ME inflammation. Pneumococcal cell wall components and pneumolysin have been studied in the model. Host inflammatory responses studied in the chinchilla ME include polymorphonuclear leukocyte oxidative products, hydrolytic enzymes, cytokine and eicosanoid metabolites, and ME epithelial cell adhesion and mucous glycoprotein production. Both clinical (tympanic membrane appearance) and histopathology (ME, Eustachian tube, inner ear) endpoints can be quantified. Immunologic and inflammatory studies have been facilitated by the production of affinity-purified antichinchilla immunoglobulin G (IgG), IgM, and secretory IgA polyclonal antibody reagents, and the identification of cross-reactivity between

    In order to study the epidemiology of acute otitis media (AOM) and Streptococcus pneumoniae nasopharyngeal colonization in the first 2 years of life, we followed up an unvaccinated birth cohort monthly and at visits when sick, with otoscopy to detect AOM and performed nasopharyngeal swabbing to detect S. pneumoniae. Serotyping of positive cultures was also performed. Of 210 babies who were enrolled at birth, 61 (29·05%) experienced 128 episodes of AOM [relative risk 2·63, 95% confidence interval (CI) 1·21-5·75] with maximum incidence in the second half of the first year of life. Episodes ranged from 1 to 7 (mean 2·1 episodes). Most (86·9%) babies with AOM had a positive culture swab giving an odds ratio (OR) of 1·93 (95% CI 1·03-3·62, P = 0·041) for this association. Other risk factors identified for AOM were winter season (OR 3·46, 95% CI 1·56-7·30, P = 0·001), upper respiratory infection (OR 2·43, 95% CI 1·43-4·51, P = 0·005); residents of small households were less likely to develop AOM (OR 0·32, 95% CI 0·17-0·57, P < 0·01). Common S. pneumoniae serotypes isolated during episodes were 19, 6, 15, 35, 7, 23, 9 and 10 which indicated a theoretical coverage for pneumococcal vaccines PCV10 and PCV13 constituent serotypes of 62·8%. We conclude that AOM in Indian infants is often associated with S. pneumoniae colonization of the nasopharynx as well as other risk factors. PMID:26931207

    Evaluation of the genetic contribution to the development of recurrent acute otitis media (rAOM) remains challenging. This study aimed to evaluate the potential association between single nucleotide polymorphisms (SNPs) in selected genes and rAOM and to analyze whether genetic variations might predispose to the development of complicated recurrent cases, such as those with tympanic membrane perforation (TMP).A total of 33 candidate genes and 47 SNPs were genotyped in 200 children with rAOM (116 with a history of TMP) and in 200 healthy controls.INFγ rs 12369470CT was significantly less common in the children with rAOM than in healthy controls (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.25-1, P = 0.04). Although not significant, interleukin (IL)-1β rs 1143627G and toll-like receptor (TLR)-4 rs2737191AG were less frequently detected in the children with rAOM than in controls. The opposite was true for IL-8 rs2227306CT, which was found more frequently in the children with rAOM than in healthy controls. The IL-10 rs1800896TC SNP and the IL-1α rs6746923A and AG SNPs were significantly more and less common, respectively, among children without a history of TMP than among those who suffered from this complication (OR 2.17, 95% CI 1.09-4.41, P = 0.02, and OR 0.42, 95% CI 0.21-0.84, P = 0.01).This study is the first report suggesting an association between variants in genes encoding for factors of innate or adaptive immunity and the occurrence of rAOM with or without TMP, which confirms the role of genetics in conditioning susceptibility to AOM.

    Full Text Available Abstract Background It is unclear why some children with acute otitis media (AOM have poor outcomes. Our aim was to describe the clinical course of AOM and the associated bacterial nasopharyngeal colonisation in a high-risk population of Australian Aboriginal children. Methods We examined Aboriginal children younger than eight years who had a clinical diagnosis of AOM. Pneumatic otoscopy and video-otoscopy of the tympanic membrane (TM and tympanometry was done every weekday if possible. We followed children for either two weeks (AOM without perforation, or three weeks (AOM with perforation, or for longer periods if the infection persisted. Nasopharyngeal swabs were taken at study entry and then weekly. Results We enrolled 31 children and conducted a total of 219 assessments. Most children had bulging of the TM or recent middle ear discharge at diagnosis. Persistent signs of suppurative OM (without ear pain were present in most children 7 days (23/30, 77%, and 14 days (20/26, 77% later. Episodes of AOM did not usually have a sudden onset or short duration. Six of the 14 children with fresh discharge in their ear canal had an intact or functionally intact TM. Perforation size generally remained very small (Streptococcus pneumoniae (82%, Haemophilus influenzae (71%, and Moraxella catarrhalis (95%; 63% of swabs cultured all three pathogens. Conclusion In this high-risk population, AOM was generally painless and persistent. These infections were associated with persistent bacterial colonisation of the nasopharynx and any benefits of antibiotics were modest at best. Systematic follow up with careful examination and review of treatment are required and clinical resolution cannot be assumed.

    2014-12-01

    Full Text Available : INTRODUCTION: Tuberculous otitis media is a rare cause of chronic suppurative infection of the middle ear and mastoid. The incidence of tuberculosis in the middle ear is very low and accounts for only 0.04% of all cases of chronic Suppurative otitis media. Its diagnosis is often delayed because it can easily be confused with other acute or chronic middle ear conditions, still the treatment of tuberculous otitis media is medical treatment with anti -tuberculous drugs and mastoid exploration if the temporal bone is involved and also to clear the disease from the middle ear cavity to avoid further complications. CASE PRESENTATION: A 21 year male patient presented with ear discharge, deafness and headache, diagnosed as primary tuberculous otitis media, treated with mastoidectomy and anti-tuberculous treatment. DISCUSSION: Primary tuberculous otitis media is very rare condition in adults, it is commonly seen in children which is also secondary to pulmonary tuberculosis / extra pulmonary tuberculosis the treatment of choice is anti tuberculous treatment for 06 months, surgery indicated to clear the disease from middle ear, temporal bone and to avoid further complications. CONCLUSION: Even though primary tuberculosis in middle ear and mastoid is very rare, the diagnosis is possible only with histological findings. In our case there was no signs of pulmonary / extra pulmonary tuberculosis, treated with mastoidectomy followed by anti - tuberculous treatment.

    2009-09-25

    Acute otitis media (AOM), one of the most common childhood diseases, is associated with a substantial medical, social and economic burden. Non-typeable Haemophilus influenzae (NTHi) and Streptococcus pneumoniae are the two main causes of bacterial OM. The 7-valent pneumococcal CRM(197)-conjugate vaccine (7vCRM, Prevnar/Prevenar, Wyeth) demonstrated efficacy against AOM caused by vaccine pneumococcal serotypes. Protection against overall AOM was also observed with an 11-valent pneumococcal protein D-conjugate vaccine (11Pn-PD) in the Pneumococcal Otitis Efficacy Trial (POET). Following POET, an optimized 10-valent pneumococcal non-typeable H. influenzae protein D-conjugate vaccine (PHiD-CV; Synflorix, GlaxoSmithKline Biologicals) was developed. This vaccine includes serotypes 1, 5, and 7F, in addition to those already included in 7vCRM, and was recently licensed in Europe for active immunization against invasive disease and AOM caused by S. pneumoniae in infants and children from 6 weeks up to 2 years of age. The use of protein D as carrier protein permits avoidance of possible interferences known to occur with some conjugate vaccines, and has the added potential benefit of providing protection against NTHi. This review seeks to highlight the recent advances in the field of OM vaccination, with a focus on data regarding the recently licensed PHiD-CV. PMID:19666154

  17. [CLINICAL APPROACH TO PEDIATRIC SEROUS OTITIS MEDIA].

    Gruber, Maayan; Honigman, Tal; Cohen-Kerem, Raanan

    2015-06-01

    Serous otitis media (also known as otitis media with effusion) is one of the most prevalent pediatric diagnoses. However, the recommended clinical approach and significance of this entity are controversial. Pathogenesis is usually based upon a combination of factors as overviewed in the body of the article. The cognitive and behavioral effects amongst children suffering serous otitis media were extensively studied and data points to little if any effects during long term follow-ups in otherwise healthy children. The therapeutic approach can be divided into watchful waiting, systemic drugs, topical drugs, mechanical therapies and surgical therapy (i.e. ventilation tube insertion). The reviewed literature mainly supports the effectiveness of the surgical approach in carefully selected cohorts of patients. PMID:26281082

  18. Three cases of tuberculous otitis media

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

    Although many studies have demonstrated an association between chronic otitis media (COM) and sensorineural hearing loss (SNHL), there still remains disagreement about the relationship. A retrospective study was conducted to examine the relationship between sensorineural hearing loss and chronic otitis media. Forty-one patients met the following criteria: unilateral COM and no history of head injury, meningitis or previous otological surgery. The differences in preoperative bone conduction threshold between diseased and control (contralateral normal) ear were statistically significant (P ossicular erosion was not associated with a significantly increased risk of sensorineural hearing loss.

    Acute otitis media (AOM) symptoms can be masked by communication deficits, common to children with autism spectrum disorders (ASD). We sought to evaluate the association between ASD and otitis media. Using ICD-9-CM diagnostic codes, we performed a retrospective case-cohort study comparing AOM, and otitis-related diagnoses among children with and without ASD. Children with ASD had a significantly increased rate of AOM, otitis media with effusion, otorrhea, and PE tube placement. Children with ASD were more than twice as likely to develop mastoiditis, and to undergo mastoidectomy and tympanoplasty. Children with ASD are more likely to have middle ear infections and otitis-related complications, highlighting the importance of routine middle ear examinations and close attention to hearing impairment in this population.

    Full Text Available ABSTRACT INTRODUCTION: Suppurative labyrinthitis continues to result in significant hearing impairment, despite scientific efforts to improve not only its diagnosis but also its treatment. The definitive diagnosis depends on imaging of the inner ear, but it is usually clinically presumed. OBJECTIVE: To analyze the clinical factors and hearing outcomes in patients with labyrinthitis secondary to middle ear infections and to discuss findings based on imaging test results. METHODS: Retrospective cohort study, based on the charts of patients admitted with middle ear infection-associated labyrinthitis. RESULTS: We identified 14 patients, eight (57% of whom were females and six (43% males. Mean age was 40 years. Cholesteatomatous chronic otitis media was diagnosed in six patients (43%, acute suppurative otitis media in six (43%, and chronic otitis media without cholesteatoma was diagnosed in two patients (14%. Besides labyrinthitis, 24 concomitant complications were identified: six cases (25% of labyrinthine fistula, five cases (21% of meningitis, five cases (21% of facial paralysis, five cases (21% of mastoiditis, two cases (8% of cerebellar abscess, and one case (4% of temporal abscess. There was one death. Eight (57% individuals became deaf, while six (43% acquired mixed hearing loss. CONCLUSION: Suppurative labyrinthitis was often associated with other complications; MRI played a role in the definitive diagnosis in the acute phase; the hearing sequel of labyrinthitis was significant.

    To determine whether otitis media affects First Nations children more severely than other children, I studied the data on otitis media occurrence among these children; on risk factors, particularly bottle feeding; and on prevention and treatment. First Nations children do seem to have more severe otitis media than other children. Health promotion might help ameliorate the situation. Supporting breastfeeding in the community is strongly recommended.

  7. New Insights into Eosinophilic Otitis Media.

    Kanazawa, Hiromi; Yoshida, Naohiro; Iino, Yukiko

    2015-12-01

    Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM. The clinical features of EOM closely resemble localized eosinophilic granulomatosis polyangiitis, therefore it is necessary to be vigilant to the symptoms of mononeuritis, polyneuritis, and skin purpura during diagnosis. Standard treatment for EOM is the instillation of triamcinolone acetonide into the mesotympanum. However, severe cases exhibiting strong inflammation and otorrhea are not easily controlled with antibiotics and/or corticosteroids. We proposed the introduction of a severity score to evaluate the severity of EOM. This score correlated with local IgE levels in middle ear effusion. Clinically, the risk factors associated with this severity score were body mass index, and the duration of bronchial asthma (from the onset of BA to the age of the first consultation of otitis media to our hospital). We emphasize that early diagnosis and adequate treatment are vital in preventing progressive and sudden hearing loss resulting from EOM. PMID:26546407

    We conducted a series of polymerase chain reactions (PCRs) in order to detect bacteria (7 species) and viruses (17 species) in middle ear fluid (MEF) and nasopharynx (Nph) of children with acute otitis media (AOM; n=179). Bacterial and viral nucleic acids were detected in MEF of 78.8% and 14.5% patients, respectively. The prevalence was as follows: Streptococcus pneumoniae, 70.4%; Haemophilus influenzae, 17.9%; Staphylococcus aureus, 16.8%; Streptococcus pyogenes, 12.3%; Moraxella catarrhalis, 9.5%; rhinovirus, 9.5%; and adenovirus, 3.4%. The overall rate of PCR-positive specimens for bacterial pathogens was 2.6 times higher, compared to culture results. The rate of PCR-positive results and the distribution of pathogens in the Nph were similar to those in the MEF. Nph PCR results had variable positive predictive values and high negative predictive values in predicting MEF findings. Our results indicate that Nph PCR could be a practical tool for examining respiratory pathogens in children with acute infections. PMID:26971180

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

    Full Text Available Abstract Background Acute otitis media (AOM is one of the most frequently encountered bacterial infections in children aged Streptococcus pneumoniae (S. pneumoniae and non-typeable Haemophilus influenzae (NTHi are historically identified as primary AOM causes. Nevertheless, recent data on bacterial pathogens causing AOM in Latin America are limited. This prospective study aimed to identify and characterize bacterial etiology and serotypes of AOM cases including antimicrobial susceptibility in Methods From February 2008 to January 2009, children ≥3 months and Results Of the 106 enrolled children, 99 were included in the analysis. Bacteria were cultured from 62/99 (63% of samples with S. pneumoniae, H. influenzae, or S. pyogenes. The most commonly isolated bacteria were H. influenzae in 31/99 (31% and S. pneumoniae in 30/99 (30% of samples. The majority of H. influenzae episodes were NTHi (27/31; 87%. 19F was the most frequently isolated pneumococcal serotype (10/30; 33%. Of the 30 S. pneumoniae positive samples, 8/30 (27% were resistant to tetracycline, 5/30 (17% to erythromycin and 8/30 (27% had intermediate resistance to penicillin. All H. influenzae isolates tested were negative to beta-lactamase. Conclusions NTHi and S. pneumoniae are the leading causes of AOM in Colombian children. A pneumococcal conjugate vaccine that prevents both pathogens could be useful in maximizing protection against AOM.

  11. Interleukin 17A promotes pneumococcal clearance by recruiting neutrophils and inducing apoptosis through a p38 mitogen-activated protein kinase-dependent mechanism in acute otitis media.

    Streptococcus pneumoniae is a Gram-positive and human-restricted pathogen colonizing the nasopharynx with an absence of clinical symptoms as well as a major pathogen causing otitis media (OM), one of the most common childhood infections. Upon bacterial infection, neutrophils are rapidly activated and recruited to the infected site, acting as the frontline defender against emerging microbial pathogens via different ways. Evidence shows that interleukin 17A (IL-17A), a neutrophil-inducing factor, plays important roles in the immune responses in several diseases. However, its function in response to S. pneumoniae OM remains unclear. In this study, the function of IL-17A in response to S. pneumoniae OM was examined using an in vivo model. We developed a model of acute OM (AOM) in C57BL/6 mice and found that neutrophils were the dominant immune cells that infiltrated to the middle ear cavity (MEC) and contributed to bacterial clearance. Using IL-17A knockout (KO) mice, we found that IL-17A boosted neutrophil recruitment to the MEC and afterwards induced apoptosis, which was identified to be conducive to bacterial clearance. In addition, our observation suggested that the p38 mitogen-activated protein kinase (MAPK) signaling pathway was involved in the recruitment and apoptosis of neutrophils mediated by IL-17A. These data support the conclusion that IL-17A contributes to the host immune response against S. pneumoniae by promoting neutrophil recruitment and apoptosis through the p38 MAPK signaling pathway.

Forty-six patients were enrolled: 23 in the cefpodoxime group and 23 in the ciprofloxacin group. Results : The clinical success rates were 95.6% in the cefpodoxime group versus 90.9% in the ciprofloxacin group. These rates are comparable, but no statistically significant difference was observed between the groups. Few mild and self-limiting AEs were observed and the tolerability of both the drugs was also good. Conclusion : The results of this randomized, open-labeled phase IV clinical trial showed that a 7-day course of cefpodoxime is therapeutically comparable to ciprofloxacin in terms of both clinical effectiveness and safety for the treatment of patients with AECSOM.

  13. Interleukin-8 expression in otitis media.

    Based on recent studies in the authors' laboratory on the correlation of cytokines and inflammation in otitis media (OM), the authors hypothesized that in chronic otitis media with effusion (COME) interleukin-8 (IL-8) is responsible for 1. the accumulation of leukocytes in the middle ear cleft and 2. in situ leukocyte activation with subsequent tissue damage. Additionally, the authors hypothesized that IL-8 expression is at least in part under the control of interleukin-1 (IL-1) and tumor necrosis factor (TNF). To begin to test this hypothesis, middle ear effusions (MEE) obtained from children ages 2 to 90 months (mean age, 29 months) undergoing tympanostomy tube placement for the presence of these inflammatory cytokines were analyzed. For these studies, IL-8, interleukin-1 beta (IL-1 beta), tumor necrosis factor-alpha (TNF-alpha), and tumor necrosis factor-beta (TNF-beta) were measured in MEE by radioimmunoassay (RIA) or enzyme-linked immunoassay (ELISA). IL-8, IL-1 beta, TNF-alpha, and TNF-beta were present in 92%, 67%, 77%, and 0% of effusions, respectively. The mean (+/- SEM) values for IL-8, IL-1 beta, and TNF-alpha were 4805 (+/- 913) pg/mg, 4076 (+/- 1510) pg/mg, and 163 (+/- 90) pg/mg. Further analysis indicated that levels of IL-8 correlated with IL-1 beta (R2 = .500, P = .000) and TNF-alpha (R2 = .387, P = .023). Thus the authors' studies clearly demonstrate that IL-8 is consistently present in the MEE of children with COME and is strongly correlated with levels of IL-1 beta and TNF-alpha, both known inducers of IL-8 production. These results support the authors' hypothesis that IL-1 beta, TNF-alpha, and IL-8 are intimately involved in the inflammatory cascade in the middle ear and suggest regulation of these cytokines as possible sites of future therapeutic intervention in otitis media with effusion (OME).

  14. Management of Otitis Media with Effusion

    LIU Li-min; DONG Min-ming

    2008-01-01

    Otitis media with effusion is one of the most common diseases in children. Its treatment remains controversial. Clinical practice guidelines of OME allow watchful waiting for 3 months before treatment if the child with OME is not at risk for speech/language/or learning problems. Tympanostomy tube insertion is the preferred initial procedure when a child becomes a surgical candidate. Complementary or alternative medicine is not recommended as a treatment for OME. This paper provides a systematic review of management of OME, which we hope will be helpful for clinicians.

    The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline "Otitis Media With Effusion in Young Children," which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children aged 1 to 3 years with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology-Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media (AOM). The subcommittee made recommendations that clinicians should (1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME; (2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk; and (3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known), or from the date of diagnosis (if onset is unknown). The subcommittee also made recommendations that (4) hearing testing be conducted when OME persists for 3 months or longer, or at any time that

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

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

    Tuberculous otitis media is a rare cause of chronic suppurative infection of the middle ear and a very uncommon form of extrapulmonary tuberculosis. Although there have been several case reports in the nonimmunosuppressive population of tuberculous otitis media, it has never been reported in an immunosuppressed allograft recipient. We present a case of diagnosed tuberculous otitis media after recurrent chronic otitis media treated several times with empiric antibiotic treatment. After the patient developed postauricular fistula and underwent surgical removal of granulation tissue, the diagnosis was made on the basis of histopathology and growth in culture of Ziehl-Neelsen. Clinical response promptly followed institution of antituberculous treatment including isoniazid, rifampicin, ethambutol, and pyrazinamide. PMID:15168420

    Bluestone, Charles D.; Swarts, J. Douglas

    2010-01-01

    The pathogenesis of otitis media is multifactorial, but the role of evolution on its development has not been addressed. We posit that the high prevalence of middle-ear disease is most likely restricted to humans, in contrast to other wild species, because the associated hearing loss would have reduced the fitness of affected individuals as a result of predation. We present here the possible consequences of two human adaptations that may have resulted in ubiquitous otitis media: the interacti...

    Otitis media has a complex multifactorial pathogenesis, and the middle ear inflammatory response is typified by the accumulation of cellular and chemical mediators in middle ear effusion. However, specific biochemical and immunochemical factors that may be responsible for the severity or chronicity of otitis media have not been identified. Identification of factors involved in chronicity appears to be an essential step in the treatment and ultimate prevention of chronic otitis media. We analyzed 70 effusion samples from patients 1 to 10 years of age who had chronic otitis media with effusion for two cytokines (interleukin-1 beta and tumor necrosis factor alpha) and total collagenase. The highest concentrations of all three inflammatory mediators were found in purulent otitis media, and concentrations were higher in younger than in older patients. Mediator concentrations were similar in samples obtained from patients having their first myringotomy for otitis media with effusion and in those who had had multiple previous myringotomies. The multiresponse star, which incorporates several biochemical parameters in one graphic illustration, may best characterize the complex nature of middle ear inflammation. PMID:8179269

  3. Eosinophilic otitis media: a new middle ear disease entity.

    Iino, Yukiko

    2008-11-01

    Eosinophilic otitis media (EOM) is intractable otitis media characterized by the presence of a highly viscous yellow effusion containing eosinophils. It occurs mainly in patients with bronchial asthma and is resistant to conventional treatments for otitis media. Here we discuss the clinical features, pathogenesis, and management of EOM. EOM predominantly affects women and presents most often in patients in their 50s. The clinical features of the middle ear in EOM are roughly divided into the otitis media with effusion type and chronic otitis media type. The latter is further divided into two subtypes: simple perforation and granulation tissue formation. EOM is often complicated by rhinosinusitis (eosinophilic sinusitis). High-tone loss is more frequently found and more severe in EOM patients than in chronic otitis media control patients, and EOM patients sometimes become deaf suddenly. Systemic or topical steroid administration is the most effective treatment for patients with EOM. The instillation of triamcinolone acetonide, a suspension of steroids, into the middle ear is very effective for controlling eosinophilic inflammation. It is very important to explain to patients with EOM that the disease may last for a long period and that progressive and sudden hearing loss may occur. PMID:18940145

  6. The Importance of Right Otitis Media in Childhood Language Disorders

    2012-01-01

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

  7. Participation of mast cells in chronic otitis media.

    2011-01-01

    In the pathogenesis of chronic otitis media (COM), much attention is paid to the molecular mechanisms of local inflammatory reactions in which mast cells (MCs) may be involved due to their role not only in allergic but also inflammatory processes. The aim of this study was to assess the density of mast cells in chronic otitis media in relationship to different clinical courses of COM, bacterial infections and types of disease. The MCs expression was measured immunohistochemically in paraffin-embedded granulation tissue specimens taken during surgery, by staining with a monoclonal antibody against tryptase. The density of tryptase-positive mast cells was lower in tissue samples from the group with a good clinical course than in those from the group with poor healing and recurrence (p = 0.006). There were no differences between the groups of patients with granulomatous and cholesteatomatous chronic otitis media (p = 0.66) or between the groups of patients with and without bacterial infection (p = 0.30), although the density of mast cells was lower for those with Pseudomonas aeruginosa/Proteus sp./ /Staphylococcus MRSA infection. In conclusion, the expression of mast cells in chronic otitis media granulation tissue was found to differ depending on the clinical course of the disease, but not on bacterial infection or type of COM. This may suggest that mast cells contribute to the maintenance of the inflammatory process, but not to antibacterial defense in chronic otitis media. PMID:22038229

    A thorough understanding of the molecular details of the interactions between bacteria and host are critical to ultimately prevent disease. Recent technological advances allow simultaneous analysis of host and bacterial protein and metabolic profiles from a single small tissue sample to provide insight into pathogenesis. We used the chinchilla model of human otitis media to determine, for the first time, the most expansive delineation of global changes in protein and metabolite profiles during an experimentally induced disease. After 48 h of infection with nontypeable Haemophilus influenzae, middle ear tissue lysates were analyzed by high-resolution quantitative two-dimensional liquid chromatography-tandem mass spectrometry. Dynamic changes in 105 chinchilla proteins and 66 metabolites define the early proteomic and metabolomic signature of otitis media. Our studies indicate that establishment of disease coincides with actin morphogenesis, suppression of inflammatory mediators, and bacterial aerobic respiration. We validated the observed increase in the actin-remodeling complex, Arp2/3, and experimentally showed a role for Arp2/3 in nontypeable Haemophilus influenzae invasion. Direct inhibition of actin branch morphology altered bacterial invasion into host epithelial cells, and is supportive of our efforts to use the information gathered to modify outcomes of disease. The twenty-eight nontypeable Haemophilus influenzae proteins identified participate in carbohydrate and amino acid metabolism, redox homeostasis, and include cell wall-associated metabolic proteins. Quantitative characterization of the molecular signatures of infection will redefine our understanding of host response driven developmental changes during pathogenesis. These data represent the first comprehensive study of host protein and metabolite profiles in vivo in response to infection and show the feasibility of extensive characterization of host protein profiles during disease.

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation has published a supplement to this issue of Otolaryngology-Head and Neck Surgery featuring the updated "Clinical Practice Guideline: Otitis Media with Effusion." To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 18 recommendations developed emphasize diagnostic accuracy, identification of children who are most susceptible to developmental sequelae from otitis media with effusion, and education of clinicians and patients regarding the favorable natural history of most otitis media with effusion and the lack of efficacy for medical therapy (eg, steroids, antihistamines, decongestants). An updated guideline is needed due to new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group. PMID:26833645

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

    Full Text Available Chronic Suppurative Otitis Media (CSOM is a condition of the middle ear that is characterized by persistent or recurrent discharge through a chronic perforation of the tympanic membrane from the middle ear cleft. Untreated cases of Chronic Suppurative Oti tis Media can result in a broad range of complications like mastoiditis, labyrinthitis, facial nerve paralysis and serious intracranial complications. In this study an attempt is made to know the aerobic bacteriology of Chronic Suppurative Otitis Media, wi th antimicrobial susceptibility testing of the bacterial isolates. The present prospective study was carried out on 50 patients presenting with Chronic Suppurative Otitis Media between January 2014 to December 2014 in the department of E.N.T, Basaveshwara Medical College Hospital and Research Centre, Chitradurga. The most common bacteria in Chronic Suppurative Otitis Media in this study was Pseudomonas aeruginosa (62% followed by Staphylococcus aureus (22%. Gentamicin was the most sensitive (100% antibio tic against Pseudomonas aeruginosa followed by Amikacin (96.77%. Ceftriaxone and Gentamicin were the most sensitive (100% antibiotic against Staphylococcus aureus followed by Amikacin (90.9%

    Full Text Available Inflammation in the middle ear mucosa, which can be provoked by different primary factors such as bacterial and viral infection, local allergic reactions and reflux, is the crucial event in the pathogenesis of otitis media with effusion (OME. Unresolved acute inflammatory responses or defective immunoregulation of middle inflammation can promote chronic inflammatory processes and stimulate the chronic condition of OME. Cytokines are the central molecular regulators of middle ear inflammation and can switch the acute phase of inflammation in the chronic stage and induce molecular-pathological processes leading to the histopathological changes accompanying OME. In this review we present cytokines identified in otitis media, immunoregulatory [interleukin (IL-2, IL-10, transforming growth factor-β] and allergy associated (IL-4, IL-5, granulocyte-macrophage colony-stimulating factor, as crucial molecular regulators, responsible for chronic inflammation in the middle ear and the chronic condition of OME.

    2011-10-01

    Full Text Available In the pathogenesis of chronic otitis media (COM, much attention is paid to the molecular mechanisms of local inflammatory reactions in which mast cells (MCs may be involved due to their role not only in allergic but also inflammatory processes. The aim of this study was to assess the density of mast cells in chronic otitis media in relationship to different clinical courses of COM, bacterial infections and types of disease. The MCs expression was measured immunohistochemically in paraffin-embedded granulation tissue specimens taken during surgery, by staining with a monoclonal antibody against tryptase. The density of tryptase-positive mast cells was lower in tissue samples from the group with a good clinical course than in those from the group with poor healing and recurrence (p = 0.006. There were no differences between the groups of patients with granulomatous and cholesteatomatous chronic otitis media (p = 0.66 or between the groups of patients with and without bacterial infection (p = 0.30, although the density of mast cells was lower for those with Pseudomonas aeruginosa/Proteus sp./ /Staphyloccocus MRSA infection. In conclusion, the expression of mast cells in chronic otitis media granulation tissue was found to differ depending on the clinical course of the disease, but not on bacterial infection or type of COM. This may suggest that mast cells contribute to the maintenance of the inflammatory process, but not to antibacterial defense in chronic otitis media.

  20. Developing a vaccine to prevent otitis media caused by nontypeable Haemophilus influenzae.

    Khan, M Nadeem; Ren, Dabin; Kaur, Ravinder; Basha, Saleem; Zagursky, Robert; Pichichero, Michael E

    2016-07-01

    Nontypeable Haemophilus influenzae (NTHi) is a predominant organism of the upper respiratory nasopharyngeal microbiota. Its disease spectrum includes otitis media, sinusitis, non-bacteremic pneumonia and invasive infections. Protein-based vaccines to prevent NTHi infections are needed to alleviate these infections in children and vulnerable populations such as the elderly and those with chronic obstructive pulmonary disease (COPD). One NTHi protein is included in a pneumococcal conjugate vaccine and has been shown to provide efficacy. Our lab has been interested in understanding the immunogenicity of NTHi vaccine candidates P6, protein D and OMP26 for preventing acute otitis media in young children. We expect that continued investigation and progress in the development of an efficacious protein based vaccine against NTHi infections is achievable in the near future. PMID:26894630

  1. A hybrid feature-based segmentation and classification system for the computer aided self-diagnosis of otitis media.

    Shie, Chuen-Kai; Chang, Hao-Ting; Fan, Fu-Cheng; Chen, Chung-Jung; Fang, Te-Yung; Wang, Pa-Chun

    2014-01-01

    We propose a novel hybrid otitis media (OM) computer aided detection (CAD) system, designed to aid in the self-diagnosis of various forms of OM. OM is a prevalent disease in both children and adults. Our system is able to differentiate normal ear from acute otitis media (AOM), otitis media with effusion (OME) and the multi-categories of chronic otitis media including perforation, retraction, cholesteatoma, etc. We propose a modified double active contour segmentation method designed for use with otoscope images, and enabled to handle user acquired data. To describe the visual symptoms (e.g., red, bulging, effusion, perforation, retraction, etc.) of otitis media accurately, we extract color, geometric and texture features by grid color moment, Gabor filter, local binary pattern and histogram of oriented gradients. A powerful classification structure based on Adaboost is used to select the most useful features and build a strong classifier. Our system achieves classification accuracy as high as 88.06% and is suitable for real use. In addition, some interesting observations about OM otoscope images are also discussed. PMID:25571030

  2. Role of computed tomography in unsafe chronic suppurative otitis media.

    Berry, S; Gandotra, S C; Saxena, N C

    1998-04-01

    Thirty Patients of Unsafe chronic suppurative otitis media were subjected to pre-operative CT scanning followed by surgical exploration of the middle ear and mastoid, and their scans were compared with the peroperative data. High resolution CT scanning has been advocated for evaluation of unsafe chronic suppurative otitis media as it is capable of delineating detail required to detect Labyrinthine fistulae, Facial canal erosion, Sinus and Dural plate erosion and Ossicular integrity. Our results showed CT scan to be highly sensitive for soft tissue density mass in the middle ear and mastoid. Dural plate exposure, Sinus plate erosion, Facial canal and Stapes integrity, moderately sensitive for Malleus and Incus integrity and least sensitive for Lateral canal fistulae. Both Axial and Coronal scans were done as many important structures are best seen in only one of these planes. The principal merit of CT scan of the Tomporal bone lies in its inherent ability to depict pathology which is not clinically evident. PMID:23119400

    Abstract Otitis media (OM) has numerous presentations in children. Together with conventional medical therapies aimed to prevent and/or treat OM, a rising number of complementary and alternative medicine (CAM) treatment options can be offered. Since OM is common in children, parents may ask healthcare professionals about possible CAM therapies. Many physicians feel that their knowledge is limited regarding these therapies, and that they desire some information. Therefore, we conducted a liter...

    2008-03-01

    In this study, we reviewed the surgical findings in a series of revision tympanomastoidectomy to determine the most common causes of failure in chronic otitis media surgery. The intraoperative findings at revision mastoidectomy with tympanoplasty of 116 patients were analyzed. The most common sites of pathologic tissue at revision surgery (with cholesteatoma and/ or granulation tissue) were unexenterated cells of the sinodural angle. The most common mechanical cause of retention of debris in canal wall down procedures was facial ridge. PMID:18298298

  9. Tuberculous otitis media: findings on high-resolution CT

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

    Full Text Available Introduction: Cholesteatomas are cystic destructive lesions that affect any pneumatized area of the temporal bone. They can cause intracranial and extracranial complications. Objective: To register the patients with complicated cholesteatomatous chronic otitis media, who were interned in the otorhinolaryngology nursing of the Clinical Hospital of São Paulo, between the years of 2001 and 2008. Method: Retrospective study involving 34 patients with complicated cholesteatomatous chronic otitis media, who had been otorhinolaryngology nursing in the Clinical Hospital of the Medicine College of the University of São Paulo, from 2001 through 2008. Results: The age of the patients ranged from 7 to 83 years, with predominance of the masculine sex (76%. The extracranial complications were more frequent than the intracranial complications, and some patients presented both types of complication. All the patients received endovenous antibiotic, and only one patient was not submitted to surgical procedure. No patient died, and in the six-month follow-up no incapacitating severe neurological sequels occurred. Conclusion: The precocious and aggressive treatment of the complicated cholesteatomatous chronic otitis media diminishes the disease morbimortality.

    2010-07-01

    Full Text Available Introduction: In spite of the fact that acute otitis media is a systemic and symptomatic disease with sever otalgia, otitis media with effusion (OME is an asymptomatic and silent disease. OME is the most common cause of conductive hearing loss in children and has adverse effects on speech development and cognitive skills. Results: Among 1001 children under study, 57 subjects (5.7% were diagnosed with OME, more than 50% of which were asymptomatic. Periodic otalgia and turning up television volume were the most common symptoms. Conclusion: Regarding the improved knowledge on diagnosis and treatment of OME especially in younger children, hearing problems or cognitive and linguistic skills retardation may be avoided by promoting general information.

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

    Popović Nikola

    2005-01-01

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

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

  19. Long term complications of ventilation tube insertion in children with otitis media with effusion

    Djordjević Vladimir

    2015-01-01

    Full Text Available Background/Aim. Otitis media with effusion (OME is characterized by the prolonged presence of fluid (longer than 12 weeks of different viscosity in the middle ear, without perforation of the eardrum or signs of acute inflammation. The conservative treatment does not always provide satisfactory recovery, so surgical treatment may be unavoidable. The aim of the study was to determine the incidence, type and frequency of complications caused by ventilation tube insertion as a part of treatment for OME in children, and specifically, to evaluate the evolution of these changes over the extended period of time. Methods. During a 5-year period (1986-1991, 84 children with chronic bilateral OME, aged from 6 months to 12 years, were enrolled in the study and treated with ventilation tube insertion. All the patients were periodically checked every 6 months over a 3-8 year period following the intervention (otomicroscopic examination, audiometry, tympanometry, and reexamined in 2013 (22-27 years after the primary surgical intervention. Results. The complications observed in this study (51% were atrophic scarring of the tympanic membrane, myringo- and tympanosclerosis, retraction of the eardrum, persistent perforations, granulation tissue formations, development of chronic otitis and sensorineural hearing loss. Conclusion. The incidence of complications after ventilation tube insertion was 51% in this study. Atrophic scars and myringosclerosis were the most prominent complications. Despite high complications rate ventilation tube insertion still remains the treatment of choice in children with otitis media with effusion.

    Sharma, Karan; Manjari, Mridu; Salaria, Neha

    2013-12-01

    Chronic mucosal diseases of middle ear cleft or chronic suppurative otitis media has been traditionally defined as a chronic inflammation of the middle ear and mastoid usually associated with perforation of the tympanic membrane and otorrhoea. Understanding the pathology and pathogenesis of chronic suppurative otitis media is important in predicting the management, prognosis and sequelae of the disease. The present prospective study was conducted to evaluate the clinical, intraoperative and histopathological changes in middle ear cleft. 100 patients diagnosed with CSOM who underwent surgery were taken. The mucosa and granulation tissue was removed along with ossicles wherever indicated and sent for histopathological examination. On clinical examination, 72 cases were found to be of tubotympanic type and 28 cases of atticoantral variety. However, intraoperatively, of the tubotympanic cases 8 were found to be of unsafe type which was also proven histologically. Stratified squamous epithelium was revealed in most of the cases accompanied by changes in the submucosa. Ossicular chain was involved in 40 cases with incus being the commonest bone to be eroded.

  6. Predominant Bacteria Detected from the Middle Ear Fluid of Children Experiencing Otitis Media: A Systematic Review.

    Chinh C Ngo

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

  8. High resolution computed tomography of chronic otitis media

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

  9. A case of direct intracranial extension of tuberculous otitis media.

    Kim, Dong-Kee; Park, Shi-Nae; Park, Kyung-Ho; Yeo, Sang Won

    2014-02-01

    We describe a very rare case of tuberculous otitis media (TOM) with direct intracranial extension. The patient was a 55-year-old man who presented to our ENT clinic for evaluation of severe headaches and right-sided otorrhea. A biopsy of granulation tissue obtained from the right external auditory canal demonstrated chronic inflammation that was suggestive of mycobacterial infection. Magnetic resonance imaging of the brain indicated intracranial extension of TOM through a destroyed tegmen mastoideum. After 2 months of antituberculous medication, the headaches and otorrhea were controlled, and the swelling in the external ear canal subsided greatly. Rarely does TOM spread intracranially. In most such cases, intracranial extension of tuberculosis occurs as the result of hematogenous or lymphogenous spread. In rare cases, direct spread through destroyed bone can occur, as it did in our patient. PMID:24526478

    2014-01-01

    Full Text Available Introduction: Chronic suppurative otitis media (CSOM is defined as infection of the middle ear that lasts for >3 months and is accompanied by tympanic membrane perforation. The incidence is higher in developing countries, especially among the low socioeconomic strata of the society. Many authors have focused their attention on the bacterial flora of CSOM, but very little is known about the mycological aspects of these, the importance of which has been increasing in the recent years. Objective: The present study was aimed to speculate the etiological fungal flora responsible for the cases of CSOM among patients who attended the Ear, Nose, and Throat Department of our hospital a tertiary care center in Uttarakhand. Materials and Methods: The total of 107 patients (both males and females who were clinically diagnosed with CSOM and were on any antibiotics (oral, topical or systemic for >14 days and still persisted with symptoms were included in this study. Results: Among the 107 cases of CSOM studied, fungi were isolated in 83 (77.57%. Majority of the patients were in second and third decades of life (62.62%. Of the 83 fungal culture positive cases, the predominantly isolated fungi were Aspergillus species (47%, Candida species (41%, and Penicillium species (9.6%. Among the Aspergillus, the predominant species were Aspergillus flavus (17 isolates and Aspergillus niger (12 isolates. Candida albicans (19 isolates and Candida tropicalis (9 isolates were the commonly isolated species of Candida. Conclusion: A definite search for fungal etiology is desirable in all cases of CSOM. Prolonged use of topical antibiotics or antibiotics-steroids ear drops may cause suppression of bacterial flora and the subsequent emergence of fungal flora. This probably increases the incidence of fungal superinfection. Otologists should suspect mycotic otitis media in patients with continuous otorrhea and who do not respond to the antibacterial treatment.

    Acute otitis media and otitis media with effusion (OME) are the main causes of hearing impairment in children which require proper treatment, mainly antibiotic therapy. Patients whom were appropriate candidates for adenoidectomy were divided into two groups regarding the presence of middle ear effusion. Adenoid tissue specimens were cultured in both groups and the bacterial flora and anti-microbial resistance pattern were determined. 72 patients were studied, 42 % had OME while 58 % did not. The following bacteria were isolated and cultured from both groups with no meaningful difference in prevalence: Streptococcus viridans (p = 0.265), Staphylococcus aureus (p = 0.72), H. influenza (p = 0.806), Entrococcus. spp (0.391), Streptococcus pneumonia (p = 0.391), nonhemolytic Streptococcus (p = 0.230). Bacterial sensitivity was similar for Amoxicillin-clavulanate (p = 0.935), Amoxicillin (p = 0.935), Cephalexin (p = 0.806), Cefixime (p = 0.391) and Azithromycin in both groups. The two groups showed no meaningful difference considering the bacterial flora of nasopharynx and their sensitivity. Bacteria in both groups were sensitive to Amoxicillin and Amoxicillin-clavulanate and resistant to Azithromycin, Cefixime and Cephalexin. PMID:25929414

    2013-03-01

    Full Text Available ABSTRACT: The significant incidence of atopy associated with otitis media with effusion (OME has suggested a role of allergy in the pathogenesis of OME. Past studies implicated allergy in the pathogenesis of otitis media [OM]. Otitis media is a common condition, especially in children. Most episodes of OM were associated with an upper res piratory viral infection and are short- lived and self-limiting with or without medical tre atment. However, chronic OM with effusion (OME has significant sequelae, is refractory to mo st medical treatments, and frequently requires surgical intervention. A large body of epid emiologic and mechanistic evidence supports a role for allergic rhinitis [AR] as a risk for OM. To establish the association of allergic rhinitis with otitis media with effusion 100 childr en of age group 5 to14 were taken, 50 children were suffering from otitis media[test group] & 50 we re healthy[control group]. These children were evaluated clinically & a battery of laboratory tests was performed in all children to establish the prevalence of allergic rhinitis in the m. Out of 50 children with otitis media 12 were suffering from allergic rhinitis & out of 50 health y children 3 were suffering from allergic rhinitis. Chi-square test was performed and the 'P0. 05' value was found to be 0.0127[uncorrected] and was highly significant. The se findings indicate that prevalence of allergic rhinitis is more in persons suffering from OME as compared to healthy individuals

  19. Dynamics of Streptococcus pneumoniae serotypes causing acute otitis media isolated from children with spontaneous middle-ear drainage over a 12-year period (1999-2010 in a region of northern Spain.

    Marta Alonso

    Full Text Available The aim of this study was to determine the serotype and clonal distribution of pneumococci causing acute otitis media (AOM and their relationship with recurrences and mixed infections with other microorganisms under the influence of the 7-valent pneumococcal conjugate vaccine (PCV7. To do this, all pneumococcal isolates collected from the spontaneous middle-ear drainage of children <5 years old diagnosed of AOM by their pediatrician or their general practitioner from 1999 to 2010 were phenotypically characterized and the most frequent serotypes were genotyped. In the 12-year study, 818 episodes of pneumococcal AOM were detected, mostly (70.5% in children younger than 2 years old. In 262 episodes (32%, the pneumococci were isolated with another bacterium, mainly (n=214 Haemophilus influenzae. Mixed infections were similar in children under or over 2 years old. The most frequent serotypes were 19A (n=227, 27.8%, 3 (n=92, 11.2% and 19F (n=74, 9%. Serotypes included in the PCV7 sharply decreased from 62.4% in the pre-vaccination (1999-2001 to 2.2% in the late post-vaccination period (2008-2010. Serotype diversity steadily increased after the introduction of the PCV7 but decreased from 2008-2010 due to the predominant role of serotype 19A isolates, mostly ST276 and ST320. The prevalence of serotype 3 doubled from 6.1% (20/326 in 1999-2004 to 14.6% (72/492 in 2005-2010. Relapses mainly occurred in male infants infected with isolates with diminished antimicrobial susceptibility. Reinfections caused by isolates with the same serotype but different genotype were frequent, highlighting the need for genetic studies to differentiate among similar strains. In conclusion, the main change in pneumococcal AOM observed after the introduction of the PCV7 was the sharp decrease in vaccine serotypes. Also notable was the high burden of serotype 19A in total pneumococcal AOM before and especially after the introduction of the PCV7, as well as in relapses and

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

  1. CLINICAL EVALUATION OF EFFECT OF GANDHAKA TAILA IN KARNASRAVA WITH SPECIAL REFERENCE TO CHRONIC SUPPURATIVE OTITIS MEDIA

    Sujatha.K

    2013-10-01

    Full Text Available Chronic suppurative otitis media (CSOM is the result of an initial episode of acute otitis media and is characterized by recurrent discharge from the middle ear through a tympanic perforation. It is an important cause of preventable hearing loss, especially in developing countries. Most approaches to treatment have been unsatisfactory or are very expensive and difficult. As per Acharya Sushruta Karnasrava is a disease characterized by ear discharge. Gandhaka taila is a unique oil based herbo-mineral formulation especially mentioned for Karnasrava with the procedure of karnapurana. To provide clinical evidence and to prove Gandhaka taila as a safe and effective medicine in chronic suppurative otitis media, this study has been carried out. In this study, 23 patients fulfilling the diagnostic and inclusion criteria of CSOM were selected and Gandhaka taila was instilled in to the affected ear for 7 days. The efficacy of the drug was analyzed in terms of the relief produced in the signs and symptoms before and after treatment. The paired t-test was used to check the significance of subjective and objective criteria. The results of the study were found encouraging and there was also a significant reduction in ear discharge.

    Full Text Available   Introduction: Ossicular chain injury is one of the most common causes of hearing loss in chronic otitis media (COM. Although definite diagnosis of ossicular discontinuity is made intraoperatively, preoperative determination of ossicular chain injury will help the surgeon decide about reconstruction options and hearing prognosis of the patient. In this study we compared preoperative pure tone audiometry (PTA findings of COM patients with the ossicular condition determined during surgery. Materials and Methods: 97 Patients with COM who underwent ear surgery for the first time were included in the study. A checklist of preoperative clinical findings, audiometric parameters and intraoperative findings was filled out for all patients. Results: Mean amount of Air-Bone Gap (ABG, Bone Conduction threshold (BC and Air Conduction threshold (AC of 97 Patients were 35.17, 13.13 and 48.30 respectively. In ears with or without cholesteatoma, granulation tissue, or otorrhea, mean of AC, BC, and ABG were not significantly different. In ossicular erosion and discontinuity (OD, mean of AC and BC thresholds increased significantly but ABG didn’t change significantly. Conclusion: According to the results of this study, in preoperative assessment of COM patients to predict ossicular condition we recommend considering AC, BC and ABG levels together instead of using ABG alone as is routine in our daily practice.

    Our aim in this study was to evaluate the efficiency of preoperative temporal bone computed tomography (CT) in detecting pathologic conditions in patients with chronic suppurative otitis media (CSOM). The intraoperative findings and temporal bone CT results of 350 patients who were diagnosed with CSOM between September 1, 2010, and June 1, 2013, were compared. Comparison parameters were as follows: the presence of cholesteatoma, erosion of the outer ear bone canal, erosion of the middle ear chain, erosion of the dural plate, erosion of the lateral semicircular canal, erosion of the sigmoid sinus wall, and dehiscence of the facial canal. The contribution of CT was limited in showing the outer ear canal destruction, dural plate destruction, facial canal destruction, lateral semicircular canal destruction, and destruction of the sigmoid sinus wall. However, CT was more sensitive in detecting cholesteatoma and erosion of the ossicular chain. These results indicate that preoperative CT of patients with CSOM serves as an important guide for otolaryngologists, although there are limitations in the evaluation of the CT results. PMID:25377960

  4. Utility and limitations of CT in otitis media

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

    Although it appears very uncommon in adult COM, Mycobacterium abscessus should be considered as a possible cause of a chronically draining ear. Multi-antibiotic chemotherapy including high-dose clarithromycin can effectively treat adult COM cased by M. abscessus. The first case report of adult chronic otitis media (COM) caused by M. abscessus is described here. A 61-year-old woman presented persistent otorrhea for 2 months, despite treatment with standard antimicrobial drugs. Physical examination revealed a small perforation of the tympanic membrane and edematous middle ear mucosa. Mycobacterial cultures and PCR yielded non-tuberculous mycobacteria (NTM); M. abscessus. Intravenous panipenem/betamipron and amikacin and oral clarithromycin were administered for 36 days. Computed tomography of the temporal bone showed improved aeration in the tympanic cavity, but soft tissue shadow remained unchanged in the mastoid 31 days after starting medication. She therefore underwent tympano-mastoidectomy at 36 days. At surgery, inflammation remained in the middle ear, and edematous pale mucosal tissue was noted around the stapes and ossicular chain. Histopathologic examination showed inflammation and granulation tissue, but no caseating necrosis or acid-fast bacilli. After surgery the symptoms resolved and remained well without evidence of infection recurrence 12 months after the operation. PMID:20206453

    Intracranial abscesses are serious complications of chronic suppurative otitis media (COM). This study included 32 patients presenting with intracranial abscesses from 780 patients hospitalized for treatment of COM. The 32 patients had 59 intracranial complications. Perisinus abscess (13 of 32) was the most common intracranial abscess, followed by temporal lobe abscess (8 of 32), epidural abscess (7 of 32), cerebellar abscess (6 of 32) and subdural empyema (2 of 32). Headache (93%), fever (87%) and altered mental status (62%) were the most common presenting symptoms and signs, along with symptoms of COM. All patients were treated with intravenous antibiotics and canal wall down mastoidectomy. Cholesteatoma with granulation tissue and bony defects at the sinus plate and/or dural plate were seen in most of the patients. Gram negative bacilli and anaerobes were the most common organisms cultured from the abscesses. Three patients had neurological sequels. One patient died. The early diagnosis of these complications requires a high index of suspicion and imaging studies. A multidisciplinary and coordinated approach is important for the management of these patients.

    2016-01-01

    Abstract Otitis media (OM) has numerous presentations in children. Together with conventional medical therapies aimed to prevent and/or treat OM, a rising number of complementary and alternative medicine (CAM) treatment options can be offered. Since OM is common in children, parents may ask healthcare professionals about possible CAM therapies. Many physicians feel that their knowledge is limited regarding these therapies, and that they desire some information. Therefore, we conducted a literature review of CAM therapies for OM, taking into account that many of these treatments, their validity and efficacy and have not been scientifically demonstrated. We performed a search in MEDLINE (accessed via PubMed) using the following terms: “CAM” in conjunction with “OM” and “children. Retrieved publications regarding treatment of OM in children which included these terms included randomized controlled trials, prospective/retrospective studies, and case studies. The following CAM options for OM treatment in children were considered: acupuncture, homeopathy, herbal medicine/phytotherapy, osteopathy, chiropractic, xylitol, ear candling, vitamin D supplement, and systemic and topical probiotics. We reviewed each treatment and described the level of scientific evidence of the relevant publications. The therapeutic approaches commonly associated with CAM are usually conservative, and do not include drugs or surgery. Currently, CAM is not considered by physicians a potential treatment of OM, as there is limited supporting evidence. Further studies are warranted in order to evaluate the potential value of CAM therapies for OM. PMID:26871802

  10. Transiently Evoked Otoacoustic Emissions in Children with Otitis Media with Effusion

    Dimitris G. Balatsouras

    2012-01-01

    Full Text Available Introduction. Otitis media with effusion is a common pediatric disease whose diagnosis is based on pneumatic otoscopy, pure-tone audiometry, and tympanometry. The aim of this study was to evaluate transiently evoked otoacoustic emissions in the diagnosis of otitis media with effusion as compared to tympanometry. Patients and Methods. 38 children with bilateral otitis media with effusion were studied. 40 normal children of similar age and sex were used as controls. All subjects underwent pneumatic otoscopy, standard pure-tone audiometry, tympanometry, and transiently evoked otoacoustic emissions. Results. In the group of children with bilateral otitis media, transiently evoked otoacoustic emissions were absent in 51 ears (67%. In the remaining 25 ears (33% the mean emission amplitude was reduced, as compared to the mean value of the control group. Conclusions. Transiently evoked otoacoustic emissions should be included in the diagnostic workup of otitis media with effusion because it is a fast, reliable, and objective test. Transiently evoked otoacoustic emissions should always be used in conjunction with tympanometry, because a more meaningful interpretation of transiently evoked otoacoustic emissions measures is possible.

    Craniofacial defects that occur through gene mutation during development increase vulnerability to eustachian tube dysfunction. These defects can lead to an increased incidence of otitis media. We examined the effects of a mutation in the Sh3pxd2b gene (Sh3pxd2b(nee)) on the progression of otitis media and hearing impairment at various developmental stages. We found that all mice that had the Sh3pxd2b(nee) mutation went on to develop craniofacial dysmorphologies and subsequently otitis media, by as early as 11 days of age. We found noteworthy changes in cilia and goblet cells of the middle ear mucosa in Sh3pxd2b(nee) mutant mice using scanning electronic microscopy. By measuring craniofacial dimensions, we determined for the first time in an animal model that this mouse has altered eustachian tube morphology consistent with a more horizontal position of the eustachian tube. All mutants were found to have hearing impairment. Expression of TNF-α and TLR2, which correlates with inflammation in otitis media, was up-regulated in the ears of mutant mice when examined by immunohistochemistry and semi-quantitative RT-PCR. The mouse model with a mutation in the Sh3pxd2b gene (Sh3pxd2b(nee)) mirrors craniofacial dysmorphology and otitis media in humans. PMID:21818352

  12. Sonotubometry Findings in Patients with combined airway disease with and without Associated Eosinophilic Otitis Media

    Ahmed Nasar, Mohammed Abd Allah, Mohammed Attia, Hasan Abd Al Naby

    2009-09-01

    Full Text Available Background: Active opening of the eustachian tube is accomplished by contraction of the paratubal muscles. Disturbance of any of the ET functions may contribute to the development of otitis media (OM with effusion and other middle ear diseases. Sonotubometry seems to be the most "physiologic" method for assessment of ET function and has the advantage that it can be performed on ears with an intact tympanic membrane and without the use of a pressure chamber. The aim of this study was to compare the Eustachian tube function using sonotubometry in patients with combined airway disease associated with Eosinophilic otitis media with that having combined airway disease without otitis media. Patients and methods: This study was applied on 45 patients divided into 3 groups each of 15. 1st group is the control group, 2nd group patients with combined airway disease without Eosinophilic otitis media, 3rd group patients with combined airway disease associated with Eosinophilic otitis media. Results: Our results explains that the tubal opening durations were significantly longer in patients of EOM group than in patients with combined airway disease without EOM group and also the normal control group.Conclusion: Sonotubometry can be performed in patients with or without an intact tympanic membrane and under physiological conditions. Sonotubometry is also inexpensive, painless, and easy to perform in both adults and children. Therefore, it has great potential value as a diagnostic tool for individuals with suspected ET disease

  13. Association of surfactant protein A polymorphisms with otitis media in infants at risk for asthma

    Bracken Michael B

    2006-08-01

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

  14. Risk factors for chronic and recurrent otitis media-a meta-analysis.

    Yan Zhang

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

    Pajor, Anna; Jankowski, Andrzej; Danilewicz, Marian; Durko, Tomasz

    2006-01-01

    In chronic otitis media molecular pathogenetic mechanisms are still unknown, however, angiogenesis may play a role. The aim of the study was to determine the intensity of angiogenesis in granulation tissue in chronic otitis media of different clinical course. Twenty six granulation tissue specimens (twenty two--from chronic otitis media, four--from prolongated otitis externa) taken during surgery were analyzed. The angiogenesis (microvessel density) was measured in paraffin-embedded tissue by an immunohistochemical method, by staining for endothelial cells with a monoclonal antibody against CD 34. The presence of CD 34 was found in all specimens. The expression was more intense in tissue samples from the group with good clinical course (good healing and without recurrence) than those in the group with poor healing and recurrence (mean number of dots for mm2 589,2 vs 533,3, respectively) and from the group without bacterial infection by Pseudomonas aeruginosa than those with this infection (mean number of dots for mm2 645,5 vs 440,8, respectively), but differences were not significant. In conclusion it is suggested that angiogenesis may contribute to different clinical course of chronic otitis media. PMID:17152811

    Full Text Available Background/Objective: We assessed the validity of computed tomography (CT in the diagnosis of complicated chronic otitis media (COM. "nPatients and Methods: The findings obtained from a pre-operative high resolution CT of temporal bone including coronal and axial views of 20 patients with complicated COM were compared to their intraoperative findings."nResults: In our study, CT was helpful in determining the anatomy of the mastoid and could accurately predict the mastoid air cell aeration, size and status of ossicles, presence of lateral semicirculal canal (SCC fistula and post-auricular fistula (All sensitivities equal to 100%. But it overdiagnosed the erosion of tegmen (positive predictive value of 50%. CT was unable to distinguish between cholesteatoma and fluid (abscess or effusion and granulation tissue or polyps and was also unable to correctly reveal the facial nerve dehiscence and had a low sensitivity for showing erosion of facial canal (50% and sigmoid sinus (60%."nConclusion: Because most complications resulting from cholesteatoma are caused by bony erosions, CT is helpful in determining the complications of COM. CT can accurately predict the extent of disease and is helpful in detection of some complications such as fistula of Lateral Semicircular Canal (LSC, erosions of dural plate and ossicular erosions. However, it is unable to distinguish between cholesteatoma, mucosal disease and fluid, and little it did contribute to detecting the facial nerve course and dehiscence. It cannot also be used for the diagnosis of the sigmoid sinus problems which could be related to no contrast administration in our study.

    2016-01-01

    Background/Aims To evaluate the characteristic properties of laryngopharyngeal reflux (LPR) and gastroesophageal reflux (GER) in children with otitis media with effusion (OME) using 24-hour multichannel intraluminal impedance combined with dual-probe (pharyngeal and esophageal) pH-metry. Methods Children aged 7–10 years of age with OME underwent 24-hour multichannel intraluminal impedance pH-metry. The upper pH sensor was situated 1 cm above the upper esophageal sphincter, and the lower pH sensor was placed 3–5 cm above the lower esophageal sphincter. Parents were asked to complete the gastroesophageal reflux assessment of symptoms in a pediatrics questionnaire. Results Twenty-eight children were enrolled; LPR was detected in 19 (67.9%) children. The criteria of the LPR diagnosis was the presence of at least one supraesophageal episode with a pH 0.2. In total, 64 episodes were observed. Assessment of all LPR episodes showed the presence of 246 episodes in the entire study. A considerable predominance of weakly acidic episodes (87.8%) was noted; there were 6.5% acidic episodes, and weakly alkaline episodes reached 5.7%. Pathological GER was noted in 10 (35.7%) subjects. Acid GER was detected in 8 children, 2 of whom demonstrated non-acidic reflux. In the LPR-negative patients, no pathological GER was confirmed with the exception of a single case of non-acidic reflux. Conclusions LPR was frequently noted in the group of children with OME, and it might be an important risk factor in this common disease. PMID:27193974

    2013-01-01

    The purpose of this study was to review our patients with complications of chronic suppurative otitis media (CSOM) and compare with literature. This retrospective study was performed over 10 years in our tertiary referral university hospital. During this period 4,630 patients with CSOM were admitted to the department and 906 patients underwent a surgery. From the records of the 4,630 patients, 121 patients (2.6%) with complications were identified. Of the 906 CSOM patients that underwent a surgery, 511 had cholesteatoma, and 395 had granulation and/or polyp tissue. Ninety-four of 511 (18.4%) patients with cholesteatoma and 27 of 395 (6.8%) patients with granulation and/or polyp tissue had a complication. Of the 121 complicated CSOM patients, 57 extracranial (47.1%) and 37 intracranial (30.6%). Multiple combined complications were occurred in 27 (22.3%) patients. The mastoid abscess was the commonest extracranial complication (28.3%); it was followed by labyrinthitis (9%), facial nerve paralysis (8.4%), and Bezold's abscess (1.3%). The most common intracranial complication was lateral sinus thrombophlebitis (19.5%), followed by perisigmoid sinus abscess (13.5%), meningitis (9%), brain abscess (6.5%), and extradural abscess (4.5%). Most frequent intraoperative finding of complicated CSOM patients was cholesteatoma, with the exception of patients with facial nerve paralysis. There was no mortality in any of our patients. The additional morbidities were recorded in 25 patients (20.6%). In this study, we emphasize the importance of an accurate and early diagnosis, followed by adequate surgical therapy and a multidisciplinary approach. PMID:22249835

    Full Text Available Objective: Chronic suppurative otitis media (CSOM can lead to dreadful and fatal complications. Objective of my study is an assessment of factors leading to the development of CSOM complications in different age groups and which age group is more prone to the development of complications. And to find out most frequent complication occurring in the target population. Introduction: CSOM is a long standing infection of a part or whole of the middle ear cleft characterized by ear discharge and a permanent perforation. It affects both sexes and all age groups. Pathways of spread of infection: Direct bone erosion, venous thrombophlebitis, preformed pathways. Classification of complications: Intracranial - Mastoiditis, facial paralysis, labrynthitis, petrositis. Extracranial - Meningitis, extradural abscess, subdural abscess, brain abscess, lateral sinus thrombophlebitis, otitic hydrocephalus. Development of complications depends upon; organism′s virulence, poor resistance of the patient, systemic disease, resistance to antibiotics, poor socioeconomic status, lack of awareness about healthcare, lack of availability of trained specialist. Materials and Methods: A descriptive cross-sectional study was carried out from 2008 to 2013 in ENT Head and Neck Surgery Department, Jinnah Postgraduate Medical Centre, Karachi. Record of 65 patients was selected through nonprobability convenient sampling; sample was divided into two groups according to age Group A 10-18 years and Group B 18-45 years.

    Amad Meimaneh Jahromi

    2010-04-01

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

  1. Pneumocephalus in cerebellopontine angle and meningitis secondary to chronic otitis media in a child

    2015-01-01

    Full Text Available Pneumocephalus is a rare complication of chronic otitis media. Despite its rarity intra-cranial air carries a potential risk of increased intra-cranial pressure or meningitis, which requires immediate therapy. A 10-year-old child presented to us with complaints of fever, headache, vomiting, and decreased hearing from left ear. He had history of left ear discharge since 2 years. Clinical examination revealed neck rigidity and left chronic otitis media. Contrast enhanced computed axial tomography scan of head [Figure 1] and [Figure 2] showed pneumocephalus in left cerebellopontine angle, opacification of left middle ear and nonpneumatisation of left mastoid. Child was immediately put on empirical intravenous antibiotics and decongestants. He showed clinical improvement in 3 days. Pneumocephalus secondary to chronic otitis media is extremely rare; we are reporting one such case in a child with review of literature.

  2. Diet as a risk factor for pneumococcal carriage and otitis media: a cross-sectional study among children in day care centers.

    Terhi Tapiainen

    Full Text Available BACKGROUND: Pharyngeal bacteria are exposed to different sugar conditions depending on the diet of the child. We hypothesized that dietary factors such as daily intake of carbohydrates could be associated with pneumococcal carriage and the occurrence of otitis media in children. METHODS: Our study design was a cross-sectional study among 1006 children attending child day care centers. Parents filled in a food frequency questionnaire. Oropharyngeal swabs were collected from each child. The primary outcome was the occurrence of pneumococcal carriage and the secondary outcome the number of acute otitis media episodes during life. Principal component analysis was used to group dietary intake into nine factors. The models were adjusted for age, gender of the child and educational level of the mother. RESULTS: The dietary factor which included high consumption of sweet pastries and jam was associated with an increased risk of pneumococcal carriage (OR 1.17, 95% CI 1.01 to 1.36, P-value 0.04. The factor including frequent consumption of fruit and berries was associated with a decreased risk of acute otitis (regression coefficient -0.51, 95% CI -0.98 to -0.03, P=0.04. A high intake of consumption of sweets and snacks (OR 1.36, 95% CI 1.03 to 1.80, P=0.03 was associated with an increased risk of caries. CONCLUSIONS: Diet was associated with a risk of pneumococcal carriage and the occurrence of otitis media. Diet may thus be a modifiable risk factor for the occurrence of acute otitis media.

    Unnecessary prescribing of antibiotics is costly, leads to serious unintended side effects, and increases the risk of developing antibiotic resistance. Children are at high risk of receiving unnecessary antibiotics because they consume more antibiotics than any other age group, likely due to inaccurate prescribing by health care providers. Treatment of acute otitis media is the most common reason children are prescribed antibiotics. Evidence-based guidelines regarding the appropriate treatment of nonsevere acute otitis media in children have been established. A retrospective, descriptive, chart review project was completed comparing the diagnosis and treatment of acute otitis media in children six months to 12 years of age in clinics and the emergency department of a large academic medical center with the American Academy of Pediatrics' treatment guidelines. Findings of the chart review included 100 patient encounters. Documentation indicated that although none of these children with acute otitis media met the guideline criteria for antibiotics, 92 of the 100 children were prescribed antibiotics. PMID:26837096

  4. Polymorphisms of immunity genes and susceptibility to otitis media in children.

    Johanna Nokso-Koivisto

    Full Text Available BACKGROUND: Acute otitis media (OM is a common disease which often develops through complex interactions between the host, the pathogen and environmental factors. We studied single nucleotide polymorphisms (SNPs of genes involved in innate and adaptive immunity, and other host and environmental factors for their role in OM. METHODS: Using Sequenom Massarray platform, 21 SNPs were studied in 653 children from prospective (n = 202 and retrospective (n = 451 cohorts. Data were analyzed for the relationship between SNPs and upper respiratory infection (URI frequency, risk of acute OM during URI episodes, and proneness to recurrent OM. RESULTS: Increased risk for OM proneness was associated with CX3CR1 (Thr280Met SNP and with a jointly interactive group of IL-10 (-1082 SNP, IL-1β (-511 wild type genotype and white race. Family history of OM proneness independently increased the risk for frequent URIs, OM occurrence during URI, and OM proneness. Additionally, IL-1β (-31 SNP was associated with increased risk for frequent URIs, but IL-10 (-592, IL-1β (-511, IL-5 (-746 and IL-8 (-251 SNPs were associated with decreased risk of URI. CONCLUSION: IL-1β (-31, CX3CR1 (Thr280Met, IL-10 (-1082 and IL-1β (-511 SNPs were associated with increased risk for frequent URIs or OM proneness.

  11. Assessment of senses of hearing and balance in chronic suppurative otitis media

    Babić Borivoj

    2008-01-01

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

    Kirkeby, S; Friis, M; Mikkelsen, H B;

    2011-01-01

    Acute otitis media (AOM) is the most common childhood infection caused by bacteria. The pathogenesis of AOM implicates initial adherence of a pathogen to the nasopharyngeal epithelium, which is followed by bacterial colonization of the middle ear cavity through the Eustachian tube. N......-acetylgalactosamine (GalNAc) is an important constituent of mucins and GalNAc containing sugar residues seem to be essential for initial adherence of respiratory bacteria to the surface of epithelial cells....

    Objective: To investigate the pathogenic bacteria distribution and drug susceptibility in children with acute otitis media (AOM) in different age and different season in the Pearl River Delta region. Method: Four hundred and forty-two children diagnosed as AOM were divided into three groups by age factor and four groups by season factor. Midge ear pus collecting and culturing were used for bacteria and antimicrobial susceptibility test. Resulted:① Strains of bacteria were isolated from 356 children with the positive rate of 80. 5%. Streptococcus pneu-moniae(39. 2%), staphylococcus aureus(25. 9%) and haemophilus influenzae(7. 4%) were the most frequently I-solated pathogens. ②Streptococcus pneumoniae was the main pathogenic bacteria in 0 - 1 year group and >1 - 3 years group(P3 years group(P0. 05). Staphylococcus aureus was the main pathogen in January-March group(P<0. 05) ;④Drug sensitivity shown that linezolid and ofloxacin were most sensitive to streptococcus pneumoniae and staphylococcus aureus, and macrolides had a good therapy effect to haemophilus influenzae. Conclusion: The pathogens distribution and drug susceptibility in children with AOM were varies in different age and different season. As a result, a treatment should be done based on the climate,environment,and pathogens distribution of a region.%目的:掌握不同年龄段及不同季节珠三角地区儿童急性中耳炎(AOM)的病原菌分布及药敏情况.方法:442例经临床确诊为AOM且临床资料完整的患儿按年龄分为0~1岁组、>1~3岁组及>3岁组,同时按就诊季节分为1~3月份、4~6月份、7~9月份、10~12月份4个组.无菌操作取中耳脓液行细菌、真菌、支原体培养并进行药敏实验.结果:①442例患儿中,356例培养阳性,阳性率80.5%,病原菌以肺炎链球菌(39.2%),金黄色葡萄球菌(25.9%)和流感嗜血杆菌(7.4%)为主;②肺炎链球菌是0~1岁组(56.9%)和>1~3岁组(32.5%)的主要病原

  15. Correlation between histomorphometric changes and the type of aerobic bacteria isolated in chronic suppurative otitis media

    Živković-Marinkov Emilija

    2011-01-01

    Full Text Available Background/Aim. Bacterial flora is a very important factor in pathogenesis of chronic suppurative otitis media (CSOM and significantly influences the type and intensity of osteolytic process. There are few histomorphometric investigations of middle ear mucosa in chronic otitis. The aim of this study was to identify aerobic bacteria responsible for chronic suppurative otitis media as well as their association with histomorphometric changes of middle ear mucosa. Methods. A prospective study that comprised 153 patients treated in the Clinc for Ear, Thorat and Nose Diseases, Niš, was conducted. Bacteriologic analysis of diseased ear secretion was carried out in all patients. Intraoperatively removed granulation tissue was used for histomorphometry. The analysed parameters were: the number of inflammatory cells, as well as vascularization and vasodilatation. Results. The most frequently isolated aerobic bacteria from chronic suppurative otitis media were Staphylococcus aureus (29.02%, Pseudomonas aeruginosa (29.02% and Proteus spp. (21.76%. There was no correlation between the type of pathologic process and the type of bacteria.The number of inflammatory cells in the granulation tissue in pure cultures of Staphylococcus aureus was 1,597.33 ± 549.45 and in Pseudomonas auriginosa cultures was 2,639 ± 648. Conclusion. This study showed that there is a statistically significant correlation between the number of inflammatory cells in the granulation tissue and the type of aerobic bacteria we isolated. The intensity of the infection in chronic suppurative otitis media depends on the type of the isolated bacteria, which emphasizes the importance of adequate preoperative antimicrobial therapy.

  16. Pneumococcal vaccination and otitis media in Australian Aboriginal infants: comparison of two birth cohorts before and after introduction of vaccination

    2009-02-01

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

    Full Text Available BACKGROUND: Otitis media (OM is a common childhood disease characterised by middle ear inflammation and effusion. Susceptibility to recurrent acute OM (rAOM; ≥ 3 episodes of AOM in 6 months and chronic OM with effusion (COME; MEE ≥ 3 months is 40-70% heritable. Few underlying genes have been identified to date, and no genome-wide association study (GWAS of OM has been reported. METHODS AND FINDINGS: Data for 2,524,817 single nucleotide polymorphisms (SNPs; 535,544 quality-controlled SNPs genotyped by Illumina 660W-Quad; 1,989,273 by imputation were analysed for association with OM in 416 cases and 1,075 controls from the Western Australian Pregnancy Cohort (Raine Study. Logistic regression analyses under an additive model undertaken in GenABEL/ProbABEL adjusting for population substructure using principal components identified SNPs at CAPN14 (rs6755194: OR = 1.90; 95%CI 1.47-2.45; P(adj-PCA = 8.3 × 10(-7 on chromosome 2p23.1 as the top hit, with independent effects (rs1862981: OR = 1.60; 95%CI 1.29-1.99; P(adj-PCA = 2.2 × 10(-5 observed at the adjacent GALNT14 gene. In a gene-based analysis in VEGAS, BPIFA3 (P(Gene = 2 × 10(-5 and BPIFA1 (P(Gene = 1.07 × 10(-4 in the BPIFA gene cluster on chromosome 20q11.21 were the top hits. In all, 32 genomic regions show evidence of association (P(adj-PCA<10(-5 in this GWAS, with pathway analysis showing a connection between top candidates and the TGFβ pathway. However, top and tag-SNP analysis for seven selected candidate genes in this pathway did not replicate in 645 families (793 affected individuals from the Western Australian Family Study of Otitis Media (WAFSOM. Lack of replication may be explained by sample size, difference in OM disease severity between primary and replication cohorts or due to type I error in the primary GWAS. CONCLUSIONS: This first discovery GWAS for an OM phenotype has identified CAPN14 and GALNT14 on chromosome 2p23.1 and the BPIFA gene cluster on chromosome 20q11.21 as

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

    Full Text Available The bicuspid aortic valve is known to be the most common congenital cardiac malformation, with an approximate incidence rate of 1-2% in the general population. Most patients are unaware of the disease until the onset of infective endocarditis, which is a life-threatening complication that may affect a heart valve or other cardiac structures at the site of endothelial damage. A 22-year-old man presented to our internal medicine clinic with a complaint of acute onset dyspnea and fatigue. His body temperature was 38 °C. A diastolic murmur was detected at the right sternal border. Two-dimensional transthoracic echocardiography revealed severe aortic insufficiency, and two-dimensional transesophageal echocardiography showed that the aortic valve was bicuspid. There was also a flail lesion extending the left ventricular outflow tract, resulting in pathological coaptation and severe aortic insufficiency. The patient was referred to our cardiovascular department for surgery. We herein present this case of a bicuspid aortic valve complicated by infective endocarditis due to the underlying disease of chronic otitis media related to a rare pathogen: Alloiococcus otitidis. The patient underwent a successful aortic valve replacement surgery due to aortic insufficiency following infective endocarditis. He was discharged on the 16th postoperative day in good condition.

  1. Mutation at the Evi1 locus in Junbo mice causes susceptibility to otitis media.

    2006-10-01

    Full Text Available Otitis media (OM, inflammation of the middle ear, remains the most common cause of hearing impairment in children. It is also the most common cause of surgery in children in the developed world. There is evidence from studies of the human population and mouse models that there is a significant genetic component predisposing to OM, yet nothing is known about the underlying genetic pathways involved in humans. We identified an N-ethyl-N-nitrosourea-induced dominant mouse mutant Junbo with hearing loss due to chronic suppurative OM and otorrhea. This develops from acute OM that arises spontaneously in the postnatal period, with the age of onset and early severity dependent on the microbiological status of the mice and their air quality. We have identified the causal mutation, a missense change in the C-terminal zinc finger region of the transcription factor Evi1. This protein is expressed in middle ear basal epithelial cells, fibroblasts, and neutrophil leukocytes at postnatal day 13 and 21 when inflammatory changes are underway. The identification and characterization of the Junbo mutant elaborates a novel role for Evi1 in mammalian disease and implicates a new pathway in genetic predisposition to OM.

    2015-01-01

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

    2006-09-01

    Full Text Available Debido a que la otitis media aguda, es la primera causa de uso de antibióticos en la edad pediátrica, es importante lograr una utilización adecuada y racional de los antibióticos en estas patologías, siendo imprescindible que antes de iniciar un tratamiento antimicrobiano se haga un buen diagnóstico clínico y se conozca el patrón microbiológico y de susceptibilidad antimicrobiana prevaleciente. La presente revisión incorpora conceptos novedosos para seleccionar la terapia antimicrobiana en niños con otitis media, tomando en cuenta principios farmacocinéticos y farmacodinámicos aplicados a conceptos microbiológicos. Estos nuevos conceptos han revolucionado el tratamiento de diversos procesos infecciosos en pediatría y superan los criterios, un poco más simples, en los que se define únicamente si una bacteria es sensible o resistente a un determinado antibiótico, incorporando aspectos fundamentarles como lo son la biodisponibilidad, la penetración del antimicrobiano al oído medio, la dosis recomendada y los intervalos entre cada dosificación.Because acute respiratory infections and particularly acute otitis media (AOM, are the most common cause of antimicrobial prescription in pediatric patients, it is important to optimize antimicrobial therapies. It is essential that before prescribing an antimicrobial agent, the AOM diagnosis is well established and the local microbiological pattern is known. The present review incorporates novel concepts for the selection of the antimicrobial therapy in children with AOM taking into account pharmacokinetic and pharmacodynamic principles applied to microbiologycal concepts. These new concepts have revolutionized the treatment of diverse infectious diseases in pediatric patients and particularly in the treatment of children with otitis media.

    1994-09-01

    Recent studies have suggested that cytokines likely play a central role in the formation and maintenance of otitis media with effusion (OME). Currently, there is no immunologically defined animal model for the study of cytokines as they contribute to the formation of OME. In the present study, a murine model of OME, using eustachian tube blockage via an external surgical approach, was developed. The murine model temporal bone histology appears to mimic the histology found in chronic otitis media with effusion in humans. Additionally, using this murine model, interleukin-1 alpha (IL-1 alpha) expression was detected in the middle ear using standard immunohistochemical techniques. IL-1 alpha seemed localized to the epithelial lining of the middle ear as well as 5% to 10% of inflammatory cells. This model should provide the necessary tool to further study the immunologic aspects of OME. PMID:8072363

  11. Pharmacoeconomic evaluation of cefaclor in the pharyngo-tonsillitis and acute otitis in children

    Mario Eandi

    2006-03-01

    Full Text Available Pharyngotonsillitis (FT and acute otitis media (OMA are among the most frequent infectious diseases of the childhood and exact a heavy toll on the Italian national health service (INHS, families and society as a whole. In case of established or suspected bacterial origin, current treatment guidelines for FT recommend 5-10 days of oral antibiotics, chosen among available penicillins, cephalosporins, or macrolides. More controversial appears the systematical use of an antibiotic for OMAs, but prevalent expert opinion suggests use of the same agents. In this paper, an economical appraisal of five of the most prescribed oral antibiotics for these indications in Italy (cefaclor, amoxicyllin, amoxicyllin/clavulanate, clarithromycin and azithromycin is provided. The evaluation was conducted through the development and implementation of two distinct models, constructed to reflect national treatment patterns of these infections. Clinical and economical data were obtained from several sources: literature review, including published meta-analyses, consultation of an expert panel and, most importantly, from the results of a specific questionnaire-based survey completed by 136 pediatricians, based throughout Italy. The models were run to conduct both cost-effectiveness and cost-minimization analyses, that consistently indicated cefaclor and amoxicyllin to be substantially equivalent in terms of total costs to the INHS and the Italian society, but significantly more convenient than amoxicyllin/clavulanate, claritrhomycin or azithromycin. Extensive probabilistic sensitivity analyses confirmed the robustness of this conclusion.

  12. Relationship between Eustachian tube function and location of the perforation in chronic otitis media

    Avick Kumar Das

    2015-01-01

    Full Text Available Background: Eustachian tube function (ETF has been the center of focus as a prognostic factor because of its presumed primary role in the pathogenesis of otitis media and clearance of the middle ear cavity. There is a general agreement that adequate ETF is necessary for middle ear surgery. In this study, the incidence of ET dysfunction and its patency has been evaluated in inactive mucosal variety of chronic otitis media, in relation to the types of central perforation. Materials and Methods: A cross-sectional study was done with 54 patients presenting with inactive mucosal type of chronic otitis media. All the recruited patients were first examined clinically and under microscope and then their audiological (impedance audiometry and radiological assessment of mastoid was done. Alongside otoendoscopy, nasal endoscopy, dye test were done. In all these cases, other routine investigations were also performed. Results: Impedance audiometry offers an easy means of assessing ETF. The automatic Toynbee test can be a practical, objective and suitable method to assess ventilatory function of ET. The saccharin test is a simple, cost-effective and is valuable diagnostic tool to assess the mucociliary function of the ET. Mucociliary and ventilatory function may vary in the same patient. Saccharin test and methylene blue tests are comparable. Patients having poor saccharin test, methylene blue test, and ventilatory test are more prone to develop central perforation posterior to the handle of the malleus. The most frequent abnormal finding at nasal endoscopy was edema about the tubal orifice. Conclusion: A clinically useful test for ETF is still lacking. Impedance audiometry offers an easy means of assessing ETF. Ventilatory function of ET which is the single most important contributory factor in the pathogenesis of chronic otitis media should be evaluated with the objective method before tympanoplasty.

    2014-01-01

    The first Genome Wide Association Study (GWAS) of otitis media (OM) found evidence of association in the Western Australian Pregnancy Cohort (Raine) study, but lacked replication in an independent OM population. The aim of this study was to investigate association at these loci in our family-based sample of chronic otitis media with effusion and recurrent otitis media (COME/ROM). Autosomal SNPs were selected from the Raine OM GWAS results. SNPs from the Raine cohort GWAS genotyped in our GWAS of COME/ROM had P-values ranging from P = 0.06-0.80. After removal of SNPs previously genotyped in our GWAS of COME/ROM (N = 21) and those that failed Fluidigm assay design (N = 1), 26 SNPs were successfully genotyped in 716 individuals from our COME/ROM family population. None of the SNP associations replicated in our family-based population (unadjusted P = 0.03-0.93). Replication in an independent sample would confirm that these represent novel OM loci, and that further investigation is warranted. PMID:25089819

  3. Tolerability of Oral Xylitol Solution in Young Children: Implications for Otitis Media Prophylaxis

    Vernacchio, Louis; Vezina, Richard M.; Mitchell, Allen A.

    2007-01-01

    Objective. Xylitol, given as two grams orally five times-a-day, significantly reduces the incidence of acute otitis media (AOM) in children. A less frequent dosing schedule, if tolerable and efficacious, would promote the more widespread use of this treatment. We sought to determine the tolerability and acceptability in young children of oral xylitol solution at doses of 5 grams three times-a-day (TID) and 7.5 grams once daily (QD). Methods. The study was a three-month randomized placebo-controlled trial of the tolerability and acceptability of oral xylitol solution in 120 children 6-36 months of age performed in the SCOR Network. Results. Study withdrawals and unscheduled medical visits for gastrointestinal complaints did not differ significantly among the study groups. The proportions of subjects in the xylitol TID group who experienced excessive gas or diarrhea at months one, two, and three were 22.7%, 10.0%, and 14.3%, respectively, and in the xylitol QD group were 27.3%, 17.4%, and 14.3%, respectively, and these did not differ from the placebo groups. The proportions who accepted the study solution easily or with only minor difficulty at one, two, and three months in the xylitol TID group were 77.3%, 90.0%, and 90.5% and in the xylitol QD group, 77.3%, 82.6%, and 90.5%, respectively. Conclusions. Oral xylitol solution at dosages of 5 grams TID and 7.5 grams QD is well-tolerated by young children. Given the potential for xylitol as a safe, inexpensive option for AOM prophylaxis, clinical trials using these dosages of xylitol can be conducted. PMID:17097152

  4. Nonencapsulated Streptococcus pneumoniae causes otitis media during single-species infection and during polymicrobial infection with nontypeable Haemophilus influenzae.

    Murrah, Kyle A; Pang, Bing; Richardson, Stephen; Perez, Antonia; Reimche, Jennifer; King, Lauren; Wren, John; Swords, W Edward

    2015-07-01

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

    were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. RESULTS: 1,816 patients were diagnosed with OM; 592 (33% had chronic OM; 1224 (67% had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8% patients were diagnosed with labyrinthine fistula, five (26.3% with mastoiditis, four (21.1% with peripheral facial palsy, and three (15.8% with labyrinthitis. CONCLUSION: The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

    Full Text Available Se realizó un estudio en 66 niños y 34 niñas de 2 a 12 años. Cincuenta fueron casos de otitis media con efusión (OME y 50 controles. El grupo etario más numeroso fue el de dos años. Los síntomas y signos más frecuentes fueron otalgia y fiebre (70% e hipoacusia (40%. Veintinueve casos (58% y sólo 12 controles (24% presentaron adenoides hipertróficas (p < 0.01 . La pérdida auditiva fue significativamente mayor en el grupo de casos y las curvas timpanométricas se relacionaron directamente con ella. No se demostró que la alergia fuera un elemento importante en la génesis de la OME, a diferencia de la hipertrofia de adenoides que constituyó nuestro hallazgo más importante.

    Between July 1988 and May 1989 we studied 100 children aged2-14 years; there were fifty cases of otitis media with effusion (OME and fifty controls. Each group Included 33 boys and 17 girls. The predominant age group was 2 years. The most frequent clinical manifestations of OME were earache and fever (70% each and reduced hearing (40%. In 29 cases (58% and in only 12 controls (24% enlarged adenoids were found (p < 0.01 . impaired hearing was significantly most frequent In the cases and the tympanometric curves had direct relationship with reduced hearing. Despite Its high prevalence allergy was not found to be of importance In the etiology of OME; by contrast, enlarged adenoids were the most relevant determinant of this disease In our series.

    Full Text Available PURPOSE To correlate the sensitivity and specificity of High Resolution Computed Tomography (HRCT findings of temporal bone in chronic otitis media with surgical findings. MATERIALS & METHODS HRCT of temporal bone of fifty patients with chronic otitis media were evaluated prospectively between July 2012 and December 2013. The various pathological findings, complications and important anatomical variations were evaluated. These findings were compared with intraoperative findings. Statistical methods were carried out using SPSS for Windows (Version 16.0 and Minitab (Version 11.0 for windows. The sensitivity, specificity, false positive and false negative rates were calculated. The level of significance was considered significant for P-values <0.05. RESULTS HRCT is reliable for all the parameters like scutum erosion, ossicular erosion, mastoid pneumatisation, low lying dura, anterior lying sigmoid, Korner’s septum, cholesteatoma extension in middle ear and mastoid, and presence of complications like mastoiditis, mastoid abscess, mastoid cortex dehiscence, sigmoid sinus plate erosion, facial canal dehiscence, tegmen mastoideum erosion, labyrinthine fistula and intracranial complications with a P value <0.05 but not reliable for tegmen tympani erosion and posterior fossa dural plate erosion. Among the findings related to adjacent neurovascular structures, facial canal dehiscence was commonest followed by anterior lying sigmoid sinus and low lying dura. In ossicular erosion, incus was most commonly involved followed by stapes and malleus. Most of the mastoid in this study was sclerotic followed by pneumatised and diploic. The epitympanum and mastoid antrum were the most commonly involved areas in cholesteatoma followed by aditus, mastoid air cells, posterior tympanum, mesotympanum, hypotympanum, protympanum and perilabyrinthine air cells in decreasing order of frequency. CONCLUSIONS HRCT temporal bone is a reliable investigation in preoperative

    2002-01-01

    To investigate the etiology and pathogenesis of cholesteatoma otitis media accompanied by cholesterol granuloma and the relationship between cholesteatoma and cholesterol granuloma, 63 cases of middle ear cholesterol granuloma treated in our hospital during the period from March 1988 to May 2000 were retrospectively reviewed. All cases were surgically and pathologically verified. 15 cases of cholesteatoma coexisting with cholesterol granuloma were found among the 63 patients. All 15 cases had a long-term history of otitis media, such as otorrhea (sanguine purulent otorrhea and bloody otorrhea in 8 cases) and perforation of the eardrum (perforation of pars flaccida in 8 cases). Temporal bone CT scans showed cholesteatoma in 11 cases. All patients were treated surgically, and cholesteatoma and cholesterol granuloma were found coexisting alternately, the latter lying mainly in the tympanic antrum, attic and mastoid air cells. Chocolate-colored mucus was accumulated in well-developed mastoid air cells, and glistening dotty cholesterol crystals were also found. In most cases, enlarged aditus, destruction of lateral attic wall, erosion of ossicular chain, exposure of horizontal segment of facial nerve and tegmen of attic were observed. Occlusion of Eustachian tube was noted in 6 cases, and occlusion of tympanic isthmus was revealed in all cases. A post-operative dry ear was achieved in all patients, and hearing improvement was achieved in all 12 cases following tympanoplasty. Cholesteatoma and cholesterol granuloma in middle ear may share a common pathophysiological etiology: occlusion of ventilation and disturbance of drainage. The diagnosis should be considered when patients presented with chronic otitis media with bloody otorrhea. CT and magnetic resonance imaging are useful for the diagnosis before operation. The surgical approach depends on the location, extension and severity of the lesion. The purpose of surgery is to remove the lesion and create an adequate

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

    Full Text Available INTRODUCTION: Chronic Suppurative otitis media (CSOM is the most common condition encountered by otolaryngologists in day to day practice. The importance of chronic otitis media lies in its dreaded complications and deafness. AIM: This study was under taken to identify the microbiological isolates of the ear discharge in CSOM cases and their sensitivity to antibiotics. SETTINGS AND DESIGN: Tertiary care hospital in north costal Andhra Pradesh. It was a Prospective study. MATERIALS & METHODS: About 100 patients having ear discharge who attended ENT outpatient department from July 2013 to Feb 2014 for a period of 8months were studied. Aural swabs were sent to microbiology lab for culture &sensitivity. RESULTS: Culture reports showed aerobic bacterial isolates in 85 cases, fungi in 7 cases and sterile in 8 cases. Of the 85 cases of aerobic bacteria, staphylococcus aureus was isolated in 34 cases (40% followed by Pseudomonas aeruginosa in 29 cases (34%, klebsiella in 16 cases (18.8%, E.coli in 4 cases (4.7% and proteus in 2 cases. Antibiotic sensitivity reports showed Staphylococcus was more susceptible to netilmycin (97%, amoxiclav (91.7% and least sensitive to ceftazidime (64.7%. Pseudomonas was more sensitive to amikacin (96.5%, gentamycin (93.1% and least sensitive to amoxyclav (79.3%, ampicillin + sulbactum (82.75%. CONCLUSION: Mono microbial etiology, especially Staphylococcus species was found to be the most common organism causing chronic otitis media. Knowledge of the prevailing flora and their susceptibility to antimicrobials will guide the clinicians for early and effective treatment thereby avoiding complications.

All cases were surgically and pathologically verified. 15 cas-es of cholesteatoma coexisting with cholesterol granuloma were found among the 63 patients. All 15 cases had a long-term history of otitis media, such as otorrhea (sanguine purulent otorrhea and blood-y otorrhea in 8 cases) and perforation of the eardrum (perforation of pars flaccida in 8 cases). Tem poral bone CT scans showed cholesteatoma in 11 cases. All patients were treated surgically, and cholesteatoma and cholesterol granuloma were found coexisting alternately, the latter lying mainly in the tympanic antrum, attic and mastoid air cells. Chocolate-colored mucus was accumulated in well developed mastoid air cells, and glistening dotty cholesterol crystals were also found. In most cases,enlarged aditus, destruction of lateral attic wall, erosion of ossicular chain, exposure of horizontal segment of facial nerve and tegmen of attic were observed.

    Background Otitis media with effusion (OME) is a disease with complicated pathogeneses which are not clearly known. Increasing interest has been focused on immunological cells, cytokines and their roles in chronic inflammatory states. This study was designed to disclose the existence and roles of interleukin-10 (IL-10) and transforming growth factor beta1 (TGF-β1) in the cause of OME in adults, and to investigate the probable role of Foxp3+CD4+CD25+ T cells in OME.Methods The concentrations of IL-10 and TGF-β1 in the middle ear effusions (MEEs) and plasmas of 36 adults (45 ears) with OME were measured by means of enzyme linked immunosorbent assay (ELISA). As contrast, the concentrations of IL-10 and TGF-β1 in the plasma of 30 normal volunteers were measured using the same method. Furthermore, the proportion of Foxp3+CD4+CD25+ T cells in CD4+ T cells of blood was tested by flow cytometry. Results (1) The concentrations of IL-10 in all MEEs and plasmas of the chronic OME patients were higher than those in patients with acute OME (both P 0.05). The concentration of IL-10 in MEEs had a strong correlation with the duration of the illness (r=0.547, P<0.01). The same correlation was also found between the concentration of TGF-β1 in MEEs and the times patients being treated (r=0.579, P <0.01). (3) The proportion of Foxp3+CD4+CD25+T/CD4+ T cells in the blood of chronic OME was not only significantly higher than that in the acute OME (P<0.01), but also higher than that in normal volunteers (P <0.01). In chronic OME, there was a correlation between the proportion of Foxp3+CD4+CD25+ T/CD4+ T cells in the blood and the concentration of IL-10 in the plasmas (r=0.602, P <0.05). Conclusions IL-10 and TGF-β1, as two important immunoregulatory mediators, participate in middle ear inflammatory response, especially in chronic course of OME in adults. Foxp3+CD4+CD25+ T cells may play some immunoregulatory roles in the course of this disease.

  15. Radiographic appearance of the middle ear after ventral bulla osteotomy in five dogs with otitis media

    Radiographs of the middle ear were made in five dogs 60 to 78 months after ventral bulla osteotomy was performed to treat otitis media. The clinical results of surgery were considered satisfactory in four dogs and unsatisfactory in one. In 4 dogs with satisfactory results, radiographs demonstrated complete reformation of the bulla in 3 operated middle ears (3 dogs), with partial bulla reformation in the three middle ears (3 dogs). Radiographs in one dog with unsatisfactory results showed complete bulla reformation with no increase in lumen opacity. The proliferative bony response obliterating the middle ear previously reported in normal dogs after ventral bulla osteotomy was not seen in any of these patients

  2. Hypertrophic chronic pachymeningitis associated with chronic otitis media and mastoiditis.

    Kanzaki, Sho; Inoue, Yasuhiro; Watabe, Takahisa; Ogawa, Kaoru

    2004-06-01

    We describe the case history of a 70-year-old female patient presenting with bilateral hearing disturbance, facial paralysis, and vertigo. Radiological tests of temporal bone revealed soft tissue in the mastoid and tympanic cavities, and T1 weighted MRI revealed prominent Gd enhancement of the middle skull basal meninges. Middle ear inflammation appeared to induce pachymeningitis and to exacerbate associated symptoms, leading to a decline in the patient's overall condition. Bilateral mastoidectomies were effective in improving her general condition. Her hearing improved only on the right side because ossiculoplasty was performed only on that side. Her facial movement progressively improved and pachymeningitis diminished over time. We speculate that removal of the infectious granulation within the middle ears and mastoids ameliorated the acute inflammation. The etiology remains unknown in this case. PMID:15121225

  3. Mucosal pathology of an experimental otitis media with effusion after X-ray irradiation

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

    Full Text Available AIM: Study; we aimed the isolation of bacteria and establishment of their susceptibility to antibiotics in patients diagnosed as Chronic Supurative Otitis Media. METHOD: Sixty-three patients were included in the study. The samples of suppurative material were cultured. Antibiotic susceptibility testing was performed as recommended by Clinical and Laboratory Standards Institute (CLSI and species was identified. RESULTS: S.aureus was isolated in 36,5 % of the 63 patients enrolled in the study. For this bacterium, increased rates of resistance to antibiotics penicillin G, ampicillin /sulbactam, gentamicin, amicacin ve TMP/SMX are detected. The other mostly isolated bacteria are P. aeruginosa (32.69% and E. coli (23.07% in turn. P. aeruginosa showed increased ratio of resistance to ceftriaxone, cefuroxime, amicacin, gentamicin, ampicillin, TMP/SMX and amoxicillin/clavulanate and also E. coli showed increased rates of resistance to gentamicin, ampicillin, ampicillin /sulbactam and amoxicillin/clavulanate. CONCLUSION: We consider Chronic Supurative Otitis Media therapy regarding antimicrobial susceptibility rates will be more rational and satisfying. [TAF Prev Med Bull 2010; 9(1.000: 51-54

  5. ROLE OF ADENOIDECTOMY IN THE MANAGEMENT OF OTITIS MEDIA WITH EFFUSION

    Avinash

    2014-06-01

    Full Text Available OBJECTIVE: To study the role of adenoidectomy in the management of otitis media with effusion. TYPE OF STUDY: A prospective clinical study. MATERIALS AND METHODS: 20cases studied in department of ENT, GMCH. The duration of study was from February 2011 to December 2011. Hearing loss assessment in the form of PTA & TYMPANOMETRY before and after adenoidectomy was done. OBSERVATIONS AND RESULTS: Children <14 years were included in the study. Sex wise distribution was observed. Patients categorized according to the symptoms, gender and degree of hearing loss. Satisfactory results observed after adenoidectomy in relation to the improvement in hearing loss. There can be some complications after adenoidectomy but in our studies proper precautions were taken and no complications seen. CONCLUSION: Adenoidectomy is a very effective surgical modality of treatment in patients who are having otitis media with effusion due to adenoid hypertrophy. Conservative management has no role and grommet insertion is not of much value. Adenoidectomy alone has been shown to produce otoscopic clearance of middle ear effusion, alteration of tympanometric status and improvement of hearing loss.

    The present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p depression (p social functioning (p < 0.001), and mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests. PMID:22566178

    2016-02-01

    Full Text Available Chronic Suppurative Otitis Media (CSOM is one of the most common chronic diseases of childhood. It is one of the common causes of deafness and can also cause permanent perforation. AIM This study was carried out to know the bacterial aetiology of CSOM and their antibiotic susceptibility pattern. MATERIALS AND METHODS Hundred patients with symptoms of CSOM who were not on antibiotics were included in the present study. Gram stain, culture and sensitivity and biochemical reactions were carried out to identify the organism and to assess their antibiotic susceptibility pattern. RESULTS The most common organism isolated in this study was Staphylococcus aureus (45.6% followed by Pseudomonas aeruginosa (34.7%, Klebsiella pneumoniae (6.5%, Proteus mirabilis (4.3%, Enterococcus fecalis (2.1%, Citrobacter koseri (2.1%, Acinetobacter baumannii (2.1% and Bacteroides (2.1%. Staphylococcal isolates showed highest susceptibility to commonly used antibiotics, gentamycin, ciprofloxacin. Most of the gram negative isolates showed susceptibility to amikacin, ciprofloxacin, third generation cephalosporins. CONCLUSION The study of microbial pattern and their antibiotic susceptibility determines the prevalent bacterial organisms causing CSOM in local area and helps to decide empirical treatment of otitis media and its complications for successful outcome, thus to prevent the emergence of resistant strains.

  8. Cytokines in children with otitis media with effusion.

    Skotnicka, B; Hassmann, E

    2000-01-01

    We assayed 38 middle ear effusions from 23 children aged 4-13 years (mean 7) undergoing tympanostomy tube placements. All fluid was assayed for tumor necrosis factor (TNF) alpha, interleukin (IL) 1beta, IL-8, and IL-10. Cytokine concentrations were measured by means of an enzyme-linked immunosorbent assay. Detectable levels of IL-1beta, IL-8, and IL-10 were found in all of the effusions. TNF-alpha was detected in 18 of the middle ear effusions (47.4%). The mean concentration of TNF-alpha, IL-1beta , IL-8, and IL-10 was, respectively, 0.423 +/- 1.39, 30.58 +/- 68.7, 7001.9 +/- 6743, and 56 +/- 58.7 pg/ml. There was a strong, statistically significant correlation between the concentrations of TNF-alpha and IL-1beta (r = 0.87, P = 0.001) and between IL-1beta and IL-8 (r = 0.53, P = 0.001). There was no correlation between the concentrations of IL-10 and other cytokines examined or between tympanic membrane pathology and the concentrations of TNF-alpha, IL-1beta , IL-8, or IL-10. The presence of IL-10 in middle ear effusions may be one of the causes of a lack of clinical features of acute inflammation and may lead to a chronic inflammatory state. PMID:10993552

  13. Otimizando o diagnóstico para o tratamento adequado das principais infecções agudas em otorrinopediatria: tonsilite, sinusite e otite média Optimizing the management of the main acute infections in pediatric ORL: tonsillitis, sinusitis, otitis media

    Tania Maria Sih

    2008-10-01

    Full Text Available As sinusites, otites médias agudas e tonsilites são muito freqüentes em crianças. A maioria dessas infecções é causada por vírus, mas em geral, elas são tratadas com antibióticos. O uso inapropriado de antibióticos favorece a seleção, crescimento e disseminação de bactérias resistentes que colonizam as vias respiratórias, atingindo toda a comunidade. A emergência de bactérias resistentes dificulta os tratamentos das infecções respiratórias, sendo essencial desenvolver estratégias efetivas para restringir o uso de antibióticos sem prejudicar as crianças que realmente precisam desses medicamentos. OBJETIVO: Analisar os resultados de estudos randomizados e controlados sobre critérios clínicos e laboratoriais utilizados para diagnóstico e tratamento das tonsilites, sinusites e otites. MÉTODOS: Levantamento dos estudos randomizados e controlados sobre o tema, publicados no MEDLINE e SCIELO, de 2000 a 2006. CONCLUSÕES: Como a maioria dessas infecções evolui bem sem antibióticos, deve-se evitar o uso desses medicamentos a menos que a criança pertença aos grupos de alto risco para complicações ou apresente persistência ou piora dos sintomas com tratamento sintomático. É necessário que os médicos e leigos conheçam melhor a evolução natural das infecções respiratórias agudas e que seja garantido o acesso das crianças a serviços médicos de boa qualidade para orientação e reavaliação, quando necessária.Sinusitis, acute otitis media and tonsillitis are very frequent in children. Most of these infections are caused by viruses, but are generally treated with antibiotics. Inappropriate use of antibiotics favors the selection, growth and spread of resistant bacteria; these bacteria colonize the airways and affect the entire community. With the emergence of antibiotic-resistant bacteria, respiratory infections have become more difficult to treat. Effective strategies are needed to restrict the use of

  14. Lipopolysaccharide induces proinflammatory cytokines and chemokines in experimental otitis media through the prostaglandin D2 receptor (DP)-dependent pathway.

    Otitis media is one of the most common and intractable ear diseases, and is the major cause of hearing loss, especially in children. Multiple factors affect the onset or development of otitis media. Prostaglandin D₂ is the major prostanoid involved in infection and allergy. However, the role of prostaglandin D₂ and prostaglandin D2 receptors on the pathogenesis of otitis media remains to be determined. Recent studies show that D prostanoid receptor (DP) and chemoattractant receptor-homologous molecule expressed on T helper type 2 (Th2) cells (CRTH2) are major prostaglandin D₂ receptors. In this study, homozygous DP single gene-deficient (DP⁻(/)⁻) mice, CRTH2 single gene-deficient (CRTH2⁻(/)⁻) mice and DP/CRTH2 double gene-deficient (DP⁻(/)⁻ CRTH2⁻(/)⁻) mice were used to investigate the role of prostaglandin D₂ and its receptors in otitis media. We demonstrate that prostaglandin D₂ is induced by lipopolysaccharide (LPS), a major component of Gram-negative bacteria, and that transtympanic injection of prostaglandin D₂ up-regulates macrophage inflammatory protein 2 (MIP-2), interleukin (IL)-1β and IL-6 in the middle ear. We also show that middle ear inflammatory reactions, including infiltration of inflammatory cells and expression of MIP-2, IL-1β and IL-6 induced by LPS, are reduced significantly in DP⁻(/)⁻ mice and DP⁻(/)⁻ CRTH2⁻(/)⁻ mice. CRTH2⁻(/)⁻ mice display inflammatory reactions similar to wild-type mice. These findings indicate that prostaglandin D₂ may play significant roles in LPS-induced experimental otitis media via DP.

  15. The Importance of Integration of Stakeholder Views in Core Outcome Set Development: Otitis Media with Effusion in Children with Cleft Palate.

    Nicola L Harman

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

  16. Nasal Mucociliary Clearance in Adenoid Hypertrophy and Otitis Media with Effusion.

    Yazıcı, Hasmet

    2015-12-01

    Mucociliary clearance (MCC), which exists in many systems, is the first defensive mechanism of the human body. Nasal MCC has an important role in transporting the secretions of the nasal cavity and paranasal sinuses along with the trapped inhaled pathogens to the nasopharynx. Physiologic or pathologic situations that effect nasal MCC, such as temperature, humidity, nasal obstruction, allergic rhinitis, chronic infections, etc., lead to impaired MCC and related local or circumjacent system disorders. With this perspective, when a unified airway with a multiple disease principle is considered, investigating the relationship between adenoid hypertrophy (AH), otitis media with effusion (OME) and nasal MCC is logical. In this review, histological and physiologic properties of nasal MCC and its possible role involving pathologic situations such as AH and OME is discussed together with recent literature findings.

  18. Antibiotic use in otitis media: patient simulations as an aid to audit.

    Chaput de Saintonge, D M; Hathaway, N R

    1981-10-01

    Diagnostic and prescribing practices in otitis media vary, and audit is difficult because doctors may not see comparable cases. Seven general practitioners took part in a pilot study to discover if simulated patients evoked the same diagnostic and treatment responses as reveal patients. Forty-eight patients entered the study over three weeks and provided data for two simulations; one included the doctor's description of the ear and the other a photograph instead. Each doctor was shown the two sets of simulations and asked to state his diagnosis and treatment. The diagnoses each doctor reached agreed significantly with those reached on the simulations of the same patients. The decisions to prescribe antibiotics also showed good agreement. PMID:6793159

    Wierzbicka, Małgorzata; Gawecki, Wojciech; Leszczyńska, Małgorzata; Kopeć, Tomasz

    2008-01-01

    The authors would like to present a rare case of the middle ear cancer which has been developed in postoperative cave in 67 years old patient operated for cholesteatoma 50 years earlier. The patient was admitted to the ENT Department of Poznań University of Medical Sciences because of the ear suppuration and headache occurring for 3 months. CT and MR images suggested granulation tissue filling the postoperative spaces with bone destruction, infiltration of the dura and temporal lobe abscess formation. Intraoperative findings allowed excluding the preliminary diagnosis of intracranial complication in the course of chronic otitis media, revealing the tissue masses resembling neoplastic infiltration. The histopathology examination confirmed the final diagnosis of squamous cell cancer. The patient was directed to radiotherapy. The authors report a case of middle ear squamous cell carcinoma and discuss its diagnostic aspect. PMID:19205537

  20. Watchful Waiting for Cases of Pediatric Otitis Media: Modeling Parental Response to Physician Advice.

    MacGeorge, Erina L; Smith, Rachel A; Caldes, Emily P; Hackman, Nicole M

    2016-08-01

    Watchful waiting (WW) can reduce unnecessary antibiotic use in the treatment of pediatric otitis media (ear infection), but its utility is impaired by underutilization and noncompliance. Guided by advice response theory, the current study proposes advantage and capacity as factors that predict how caregivers evaluate and respond affectively to WW. Parents (N = 373) of at least 1 child age 5 years or younger completed questionnaires that assessed responses to hypothetical WW advice for their youngest child. Perceptions of advantage from WW and the capacity to monitor and manage symptoms predicted advice quality, physician trust, and future compliance both directly and indirectly through negative affect. The findings suggest the elaboration of advice response theory to include more aspects of advice content evaluation (e.g., advantage) and the influence of negative affect. The study also provides practical guidance for physicians seeking to improve caregiver reception of WW advice. PMID:27409041

  1. Modeling Analysis of Biomechanical Changes of Middle Ear and Cochlea in Otitis Media

    Gan, Rong Z.; Zhang, Xiangming; Guan, Xiying

    2011-11-01

    A comprehensive finite element (FE) model of the human ear including the ear canal, middle ear, and spiral cochlea was developed using histological sections of human temporal bone. The cochlea was modeled with three chambers separated by the basilar membrane and Reissner's membrane and filled with perilymphatic fluid. The viscoelastic material behavior was applied to middle ear soft tissues based on dynamic measurements of tissues in our lab. The model was validated using the experimental data obtained in human temporal bones and then used to simulate various stages of otitis media (OM) including the changes of morphology, mechanical properties, pressure, and fluid level in the middle ear. Function alterations of the middle ear and cochlea in OM were derived from the model and compared with the measurements from temporal bones. This study indicates that OM can be simulated in the FE model to predict the hearing loss induced by biomechanical changes of the middle ear and cochlea.

  2. Unusual pseudomyiasis with Musca domestica (housefly larvae in a child with chronic otitis media

    Zafar Iqbal

    2016-01-01

    Full Text Available Myiasis is a disease caused by fly larvae and aural myiasis is a rare clinic condition often occurring in children or mentally retarded people. We report the case of an unusual presentation of a unilateral aural myiasis in a 3-year-old female child patient belonging to a slum with unilateral chronic otitis media caused by Musca domestica (housefly larvae. Eight larvae were removed from the external auditory canal while five more larvae were located in the middle ear cavity and were removed through perforation of the tympanic membrane. Management of ear myiasis is based on removal of the maggots and cleansing of the ear with ethanol, chloroform, or physiological saline. Physiological saline is preferred in patients who have tympanic membrane perforation. Myiasis is related to personal hygiene. Therefore, to decrease the incidence of these infestations, care, and hygiene standards should be carried out for those at risk through information, education, and communication.

  3. Radiological study of the temporal bone in chronic otitis media: Prospective study of 50 cases

    2014-01-01

    Full Text Available Aim: To assess radiological findings in Chronic otitis media (COM, its involvement in middle ear and adjacent structure and to compare with similar published data. The ability of the radiological investigations to detect the various pathological and anatomical variations were evaluated and compared with intraoperative findings. COM is a long standing inflammation of the middle ear cleft without reference to etiology or pathogenesis. Due to the strategic location of the tympanomastoid compartment, separated from the middle and posterior cranial fossa by the thinnest of bony partitions, otitis media has the potential for intracranial extension. Hence, it becomes very important to know the location and extent of the disease before proceeding to surgical treatment. Radiological examination of the temporal bone helps us to achieve this objective. The present work has been undertaken to study the role of radiological imaging of the temporal bone as a diagnostic modality in COM and its use in determining the lines of management as in the type of surgical intervention required. Materials and Methods: This is a prospective study in which total of 50 cases with COM were studied. Results: HRCT is reliable for all the parameters like scutum erosion, ossicular erosion, mastoid pneumatisation, low lying dura, anterior lying sigmoid, Korner′s septum, cholesteatoma extension in the middle ear and mastoid, and presence of complications such as mastoiditis and mastoid abscess, mastoid cortex dehiscence, sigmoid sinus plate erosion, facial canal dehiscence, tegmen mastoideum erosion and labyrinthine fistula and intracranial complications with a P < 0.05 but not reliable for tegmen tympani erosion and posterior fossa dural plate erosion. Conclusion: HRCT is highly reliable and findings are in par with intraoperative findings in this study.

  4. HIF-VEGF pathways are critical for chronic otitis media in Junbo and Jeff mouse mutants.

    2011-10-01

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

    Vishal Sharma* and Gagandeep Kaur

    2014-05-01

    Full Text Available Chronic suppurative otitis media (CSOM is a chronic inflammation of the middle ear and mastoid cavity that presents as ear discharge. If untreated it can lead to various intracranial and extra cranial complications. This prospective study was carried out to find out various agents causing chronic suppurative otitis media and do determine the antibiogram. A total of 170 patients presenting with ear discharge were included in this study.  Specimen processing, organism isolation, identification and antibiotic susceptibility were performed as per standard protocols. Pseudomonas aeruginosa was the most common organism isolated followed by Staphylococcus aureus, coagulase negative staphylococci, Klebsiella, Proteus, Aspergillus and Candida. Antimicrobial sensitivity pattern of bacterial isolates showed a variable pattern. Of the most common antibiotics available as topical preparations, gentamicin and ciprofloxacin were highly effective against study isolates. Empirical therapy followed by definitive treatment can help prevent emergence of resistance to various antimicrobial agents in these cases.

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

  15. Auditory processing abilities in children with chronic otitis media with effusion.

    Khavarghazalani, Bahare; Farahani, Farhad; Emadi, Maryam; Hosseni Dastgerdi, Zahra

    2016-05-01

    Conclusion The study results indicate that children with a history of otitis media with effusion (OME) suffer from auditory processing disorder to some degree. The findings support the hypothesis that fluctuating hearing loss may affect central auditory processing during critical periods. Objectives Evidence suggests that prolonged OME in children can result in an auditory processing disorder, presumably because hearing has been disrupted during an important developmental period. A lack of auditory stimulation leads to the abnormal development of the hearing pathways in the brain. The aim of the present study was to determine the effects of OME on binaural auditory function and auditory temporal processing. Method In the present study, the dichotic digit test (DDT) was used for binaural hearing, and the gap in noise (GIN) test was used to evaluate temporal hearing processing. Results The average values of GIN differed significantly between children with a history of OME and normal controls (p < 0.001). The mean values of the DDT score were significantly different between the two groups (p = 0.002). PMID:26881324

    2012-03-01

    This study aimed to compare the veracity of computed tomography findings on patients undergoing surgery for chronic otitis media (COM) with the surgical findings, and to determine to what extent the preoperative computerized tomography (CT) findings are useful to the surgeon. A series of 56 patients with COM undergoing preoperative CT scanning followed by surgical exploration of the middle ear and mastoid. Operative notes were recorded and data collected on the nature of soft tissue masses, the status of the ossicles, presence or absence of facial canal dehiscence and semicircular canal (SCC) dehiscence and the presence or absence of dural plate erosion, and sigmoid sinus thrombosis. Fifty-six patients were recruited in the study, 30 males and 26 females. The age range was from 16 to 67 years with a mean of 26.51 ± 1.4 years. The preoperative CT scan imaging in cases of cholesteatoma, ossicular chain erosion and SCC dehiscence have good correlation with the intraoperative findings. The specificity of preoperative CT scan in detecting facial canal dehiscence, dural plate erosion and sigmoid sinus thrombosis in patient of COM were weak. Preoperative computed tomography evaluation is fairly useful especially in cases of cholesteatoma. According to the results of this study, CT is of value particularly in the definition of cholesteatoma, and in determining ossicular chain erosion and semicircular canal fistula. PMID:23449285

    Prata, Anelise Abrahao Salge

    2011-01-01

    Full Text Available Introduction: The chronic otitis media (COM is a prevalent disease and the most frequent cause of indication to mastoidectomy. Many studies have evaluated the use of tomography (CT of temporal bones for preoperative evaluation of COM and its indication in the preoperative approach is still controversial nowadays. Objective: To evaluate the sensitivity of the clinical and radiological findings of COM according to the intraoperative surgical results and histopathological findings. Method: Transversal retrospective study through collection of record data of patients with COM submitted to mastoidectomy in the period from 2007 through 2008 in our service. Results: From a total of 82 ears, 40.24% had cholesteatoma. The CT presented 72.73% of sensitivity in the identification of cholesteatoma, 56.67% in the identification of changes to the ossicular chain and 100% in that of erosion of the lateral semicircular canal. Conclusion: The clinical and radiological findings showed a high level sensitivity with intraoperative findings as regards to the presence of cholesteatoma, large changes of the ossicular chain and erosion of the lateral semicircular canal. For minor changes to the ossicular chain, the facial nerve canal and the tympanic tegmen they described low sensitivity.

    The major burden of chronic suppurative otitis media (CSOM) is the embarrassing ear discharge which may last for few months to many years or even a lifetime with increasing risks of complications. We conducted this study to determine the risk factors for protracted non-healing ear discharge among CSOM patients. We carried out a retrospective analysis of non-cholesteatomatous CSOM patients treated in a tertiary hospital in a developing country. Comparison was made between 128 patients with ear discharge persisting beyond 24 months and 58 patients whose otorrhoea resolved within 6 months in terms of socio-demographic and other potential risk factors. Major risk factors identified by logistic regression analysis were rural residence, multidrug-resistant bacteria, and bilateral CSOM (P = 10 miles away from hospital, and >7 persons in a family (P = 0.012, 0.041, 0.013, 0.010, and 0.043, respectively). Age, sex, nasal allergy, and self-medication were not significant risk factors for non-healing ear discharge. Protracted non-healing ear discharge still remains a prominent feature of CSOM in our experience. Rural residence, multidrug resistance, bilateral CSOM, and long distance to health facilities are prime risk factors. Measures to address these risk factors to bring about a decline in the number of non-healing ear discharge among CSOM patients, especially in our rural communities, are urgently needed.

    Helicobacter pylori is a Gram-negative bacterium that is recognized as one of the key factors in gastric diseases such as gastritis, peptic ulcer and gastric cancer. Recent studies have shown relationships between H. pylori and extra-digestive diseases, and the presence of H. pylori in the middle ear and upper respiratory tract has been reported. However, the role of H. pylori in middle ear disease remains unclear. The present study demonstrated that H. pylori whole-cell protein directly induces macrophage migration inhibitory factor, macrophage inflammatory protein 2, interleukin 1 beta and tumor necrosis factor alpha in middle ear epithelium in mice, and severe proliferation of inflammatory cells was observed in middle ear cavity inoculated with H. pylori whole-cell protein. In addition, trans-tympanic injection of macrophage migration inhibitory factor up-regulated expression of macrophage inflammatory protein 2 in the middle ear. These findings indicate that H. pylori infection causes immunological inflammation in middle ear epithelium, and H. pylori may play a significant role in otitis media. PMID:18727622

    The objective of this study was to determine tympanostomy tube complications in children with chronic otitis media with effusion who were treated with Shepard grommet tympanostomy tube insertion. This tube type was selected as it is the most commonly used one in our clinic. The medical records of 162 ears of 87 children (52 male and 35 female) were reviewed retrospectively. The children were between 3 to 16 years old (mean age = 8.1 +/- 3.1). The patients were followed up 6-66 months (mean 23.3 +/- 14.9 months) after tympanostomy tube insertion. We reviewed age, sex, time to tube extrusion and complications. In all patients the indication for surgery was chronic middle ear effusion. Otorrhea occurred in nine ears (5.6%). Granulation tissue was seen in two ears (1.2%). Complications after tympanostomy tube extrusion included myringosclerosis (34.6%), persistent perforation (5.6%), atrophy (23.5%), retraction (16.7%) and medial displacement of tubes (1.2%). The average extrusion time was 8.5 +/- 4.6 months (range 1-24) for Shepard grommet tympanostomy tubes. Complications of tympanostomy tube insertion are common. Myringosclerosis, tympanic membrane atrophy and otorrhea are the most frequently appearing complications. But they are generally insignificant and cosmetic. Consequently, in the majority of these complications there is no need for any management. PMID:20204390

    .On the basis of research evidence, a recommended strategy for improving the care of middle ear infections is to identify the subset of patients least likely to benefit from antibiotic therapy. They include children ages 6 months to 23 months with unilateral disease without severe signs and symptoms (moderate or severe otalgia, otalgia lasting more than 48 hours,or temperature of 39°C [102.2°F]), and those older than 2 years ofage with unilateral or bilateral disease who have mild signs andsymptoms.(9) On the basis of research evidence, the initial treatment of otitis media with effusion is watchful observation. There is little harm in observing a child who is not at risk for speech, language, or learning difficulties compared to medical or surgical intervention.(4) On the basis of research evidence, administration of the annual influenza vaccine and the conjugated pneumococcal vaccination has been shown to have a small but statistically significant impact on the frequency of middle ear disease. (7)(8) On the basis of expert opinion, optimal outcomes depend oncommunication between clinicians and parents. At a minimum , primary care clinicians should state their reasons for their own clinical judgment about appropriate management and for referral to otolaryngology if necessary. PMID:26527627

    Otitis media (OM) has numerous presentations in children. Together with conventional medical therapies aimed to prevent and/or treat OM, a rising number of complementary and alternative medicine (CAM) treatment options can be offered. Since OM is common in children, parents may ask healthcare professionals about possible CAM therapies. Many physicians feel that their knowledge is limited regarding these therapies, and that they desire some information. Therefore, we conducted a literature review of CAM therapies for OM, taking into account that many of these treatments, their validity and efficacy and have not been scientifically demonstrated.We performed a search in MEDLINE (accessed via PubMed) using the following terms: "CAM" in conjunction with "OM" and "children. Retrieved publications regarding treatment of OM in children which included these terms included randomized controlled trials, prospective/retrospective studies, and case studies.The following CAM options for OM treatment in children were considered: acupuncture, homeopathy, herbal medicine/phytotherapy, osteopathy, chiropractic, xylitol, ear candling, vitamin D supplement, and systemic and topical probiotics. We reviewed each treatment and described the level of scientific evidence of the relevant publications.The therapeutic approaches commonly associated with CAM are usually conservative, and do not include drugs or surgery. Currently, CAM is not considered by physicians a potential treatment of OM, as there is limited supporting evidence. Further studies are warranted in order to evaluate the potential value of CAM therapies for OM. PMID:26871802

    Background and Objectives Pneumatization of air cells in the mastoid bone is decreased in chronic otitis media (COM). A decrease in the size of the external auditory canal (EAC) is also found frequently in patients with COM, but this has been little studied. We compared the size of affected bony EACs and the contralateral side in patients with single-side COM using high-resolution computed tomography. Subjects and Methods In total, 99 patients with single-side COM were included. Four indicators related to the size of the bony EAC and IAC were measured using high-resolution computed tomography: the axial and coronal lengths of the tympanic membrane, the length of the isthmus, and the area of the bony ear canal. We also compared both internal auditory canals as negative controls. These assessments were made by radiologists who were blinded to the objective of this study. Results In patients with single-side COM, the axial length of the tympanic membrane was significantly shorter than normal, and the volume of the EAC was also significantly smaller. The length of the isthmus of the EAC was shorter on the affected side, but the difference was not significant. The IAC volume showed no difference between the two sides. Conclusions COM affects general temporal bony development, including the bony EAC and mastoid bone. Therefore, whether to correct this should be considered when preparing for COM surgery.

  4. Evolution and Otitis Media: A Review, and a Model to Explain High Prevalence in Indigenous Populations.

    Bhutta, Mahmood F

    2015-04-01

    Otitis media (OM; inflammation of the middle ear) comprises a group of disorders that are among the most common disorders of childhood. OM is also heritable and has effects on fecundity. This means that OM is subject to evolution, yet the evolutionary forces that may determine susceptibility to OM have not been adequately explored. Here I analyze evolutionary forces that may determine susceptibility to middle ear inflammation. These forces include those affecting function of the middle ear, host immunity, or colonization by and pathogenicity of bacteria. I review existing evolutionary models of host-pathogen interaction and coevolution and apply these to better understand the complex evolutionary landscape of middle ear infection and inflammation in humans, including factors determining transition between stable evolutionary strategies for host and bacteria. This understanding is then applied to an analysis of OM in indigenous populations to devise a new theory for OM prevalence in Australian Aborigine, Native American, Inuit, and Maori populations. I suggest that high prevalence in such groups may have resulted from encounters of these previously isolated populations with European immigrants in the 15th and 16th centuries. This exposed them to new strains of bacteria to which their immune system had not evolved immunity, perturbing a previously stable host-pathogen coevolutionary state. PMID:26829293

  5. Virulence phenotypes of low-passage clinical isolates of Nontypeable Haemophilus influenzae assessed using the chinchilla laniger model of otitis media

    2007-06-01

    Full Text Available Abstract Background The nontypeable Haemophilus influenzae (NTHi are associated with a spectrum of respiratory mucosal infections including: acute otitis media (AOM; chronic otitis media with effusion (COME; otorrhea; locally invasive diseases such as mastoiditis; as well as a range of systemic disease states, suggesting a wide range of virulence phenotypes. Genomic studies have demonstrated that each clinical strain contains a unique genic distribution from a population-based supragenome, the distributed genome hypothesis. These diverse clinical and genotypic findings suggest that each NTHi strain possesses a unique set of virulence factors that contributes to the course of the disease. Results The local and systemic virulence patterns of ten genomically characterized low-passage clinical NTHi strains (PittAA – PittJJ obtained from children with COME or otorrhea were stratified using the chinchilla model of otitis media (OM. Each isolate was used to bilaterally inoculate six animals and thereafter clinical assessments were carried out daily for 8 days by blinded observers. There was no statistical difference in the time it took for any of the 10 NTHi strains to induce otologic (local disease with respect to any or all of the other strains, however the differences in time to maximal local disease and the severity of local disease were both significant between the strains. Parameters of systemic disease indicated that the strains were not all equivalent: time to development of the systemic disease, maximal systemic scores and mortality were all statistically different among the strains. PittGG induced 100% mortality while PittBB, PittCC, and PittEE produced no mortality. Overall Pitt GG, PittII, and Pitt FF produced the most rapid and most severe local and systemic disease. A post hoc determination of the clinical origins of the 10 NTHi strains revealed that these three strains were of otorrheic origin, whereas the other 7 were from patients

    2016-06-01

    Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy. PMID:26078091

    To determine the incidence of otogenic complications of Chronic suppurative otitis media (CSOM) and its management. The study was conducted at the tertiary referral centre and teaching hospital. An analysis was made about the clinical and operative findings, surgical techniques and approaches, the overall management and recovery of the patient. The data were then compared with the relevant and available literature. Over the study period of 12 years, a total 45 cases of CSOM with complications were reviewed. Out of these 45 cases, 20 cases had extracranial (EC) while 25 cases had intracranial (IC) complications. The prevalence of each complication was 0.17 and 0.13 %, IC and EC respectively. The commonly encountered IC complications were brain abscess, meningitis and lateral sinus thrombophlebitis. Among the EC complications, mastoid abscess followed by labyrinthitis and facial nerve palsy were encountered. The reliable warning signs and symptoms of IC complications were fever, headache, earache vestibular symptoms, meningeal signs and impairment of consciousness. Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus epidermidis were the common organism isolated. Cholesteatoma and granulation in the middle ear were the major findings in both groups of cases. Surgery was main modality of management of these conditions. We observed that two patients fail to regain full facial nerve function despite of surgery. Mortality rate was zero but morbidity was seen in 15 % (3) and 28 % (7) of cases in EC and IC group respectively. The epidemiological presentation, clinical features and results of treatment are discussed. CSOM complications, despite its reduced incidence still pose a great challenge in developing countries, as the disease present in the advanced stage leading to difficulty in management and consequently higher morbidity. In this study we emphasize the importance of the accurate and early diagnosis followed by adequate surgical therapy with

    Full Text Available Purpose: To determine the prevalence of Otitis media (OM and Early childhood caries (ECC and their coexistence in children with a history of faulty feeding patterns. Method: Children aged 5 years and below were recruited at random from dental and medical hospitals. Parents of these children were posed with questions about the feeding methods, feeding patterns such as duration, frequency, position, burping, specific childhood illness etc. Children (120 were examined for ECC by a Paedodontist and OM by an Otolaryngologist and were segregated into three groups i.e. Control group, ECC group and OM group respectively. The ECC group was sub grouped into ECC only and ECC&OM group. The OM group was also similarly sub grouped into OM group and OM&ECC group. Collected data were tabulated and subjected for statistical analysis using Pearson Chi – square test. Results: Prevalence of ECC, OM, and their coexistence increased with age P < 0.001, whereas gender difference was not statistically significant. Overall Prevalence of their coexistence in children was 51.25%. Significant percentages (25% of children in the OM group were fed in supine position. Children fed on demand (47.5% experienced ECC. overall 85% (p=.017 of children had coexistence of ECC&OM fed on demand and during bed time. Significant numbers of children who were burped occasionally after feeding (35% or were not burped at all (12.5% were affected with both ECC and OM. Conclusion: Prevalence of their coexistence was higher in children with OM. Significant association existed between on demand feeding and ECC; supine feeding position and OM. Risk factors in common for both the disease were combined feeding position, on demand, bed time feeding and occasionally burping.

    2015-06-01

    Full Text Available Background: Chronic Suppurative Otitis Media (CSOM is the major cause of hearing impairment, mainly conductive type of hearing loss. The occurrence of sensorineural hearing loss (SNHL in CSOM is controversial and the controversy is more for safe mucosal type. This study aims to assess the association between SNHL and safe mucosal CSOM and its relation to patient's age, sex, duration of disease, active or inactive disease and speech frequencies. Methods: 100 patients with unilateral mucosal type of CSOM with normal contralateral ear were included in the study. The infected ear was taken as study ear and normal ear as control ear in all patients. All patients underwent hearing assessment by pure tone audiometry for both ears. In case of active disease, ear discharge was first cleared and then audiometric assessment done. Results were statistically compared in all patients for both study and control ears using parameters of patient's age, sex, duration of disease, speech frequency and active or inactive disease. Results: There was significant higher number of study ears with CSOM having average bone conduction threshold of all frequencies above 25 decibels which implies SNHL (21% compared to control contralateral ears without infection (5%. There was higher incidence of SNHL at higher speech frequencies. The incidence also increased with age of patient and duration of disease. The incidence was higher in active stage than inactive or quiescent stage. There was no difference among males and females. Conclusion: Safe mucosal CSOM can cause significant SNHL and risk increases with increasing age, duration of disease, higher speech frequencies and presence of active disease.

  12. The Toll-Like receptor adaptor TRIF contributes to otitis media pathogenesis and recovery

    Pak Kwang

    2009-08-01

    Full Text Available Abstract Background Toll-like receptor (TLR signalling is crucial for innate immune responses to infection. The involvement of TLRs in otitis media (OM, the most prevalent childhood disease in developed countries, has been implicated by studies in middle ear cell lines, by association studies of TLR-related gene polymorphisms, and by altered OM in mice bearing mutations in TLR genes. Activated TLRs signal via two alternative intracellular signaling molecules with differing effects; MyD88 (Myeloid differentiation primary response gene 88 inducing primarily interleukin expression and TRIF (Tir-domain-containing adaptor inducing interferon β mediating type I interferon (IFN expression. We tested the hypothesis that TRIF and type I IFN signaling play a role in OM, using a murine model of OM induced by non-typeable Haemophilus influenzae (NTHi. The ME inflammatory response to NTHi was examined in wild-type (WT and TRIF-/- mice by qPCR, gene microarray, histopathology and bacterial culture. Results Expression of TRIF mRNA was only modesty enhanced during OM, but both type I IFN signalling genes and type I IFN-inducible genes were significantly up-regulated in WT mice. TRIF-deficient mice showed reduced but more persistent mucosal hyperplasia and less leukocyte infiltration into the ME in response to NTHi infection than did WT animals. Viable bacteria could be cultured from MEs of TRIF-/- mice for much longer in the course of disease than was the case for middle ears of WT mice. Conclusion Our results demonstrate that activation of TRIF/type I IFN responses is important in both the pathogenesis and resolution of NTHi-induced OM.

  13. The rationale for preventive treatments for early post-tympanostomy tube otorrhea in persistent otitis media with effusion.

    Some studies have shown that post-tympanostomy tube otorrhea (PTTO) is a common complication after tympanostomy tube insertion. There are wide range of controversies about the incidence of PTTO and different methods of preventive treatment. The aim of this study was to determine the incidence of early PTTO in persistent otitis media with effusion in our centers. We also investigated the effect of preventive treatments on the incidence of early PTTO in children with persistent otitis media with effusion. This multi-central study comprised 536 ears belonging to children with otitis media and effusion for at least 3 months, referred for complications arising from post-tympanostomy tube insertion. The patients were randomly divided into three treatment and control groups. In the first group of patients, the middle ear cavity was irrigated with isotonic saline after myringotomy. The second group received oral amoxicillin three times a day for 7 days postoperatively. The third group had similar treatment as the second group, in addition to topical ciprofloxacin drop, 4 drops three times a day for 3 days after operation. The control group did not undergo any treatment. Early post-tympanostomy tube otorrhea was detected in 6 ears (1.1 %), including 3 (2.2 %) from the control group and 3 (2.3 %) from the first group. There was no statistically significant difference in early PTTO between integrated treatment groups and control group (P = 0.111). As the total rate of early post-tympanostomy tube otorrhea was very low, there was no significant difference between the 3 treatment groups and control group. Our study did not support the routine use of preventive therapy. A period of at least 3 months watchful waiting before tympanostomy tube insertion may help reduce the incidence of PTTO.

  16. Relationship of endotoxin to tumor necrosis factor-alpha and interleukin-1 beta in children with otitis media with effusion.

    Willett, D N; Rezaee, R P; Billy, J M; Tighe, M B; DeMaria, T F

    1998-01-01

    Sixty-five middle ear effusions and paired sera from 41 children with chronic otitis media with effusion were assayed for endotoxin and for tumor necrosis factor alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in order to establish whether a correlation exists between the concentrations of endotoxin and of these cytokines. Endotoxin concentration was determined by means of a chromogenic limulus amebocyte lysate assay, and the cytokine concentration by means of a quantitative enzyme-linked immunosorbent assay. Forty percent of the effusions had detectable levels of endotoxin, with a mean concentration of 2.9 +/- 7.8 endotoxin units per milligram of total protein. The mean concentration of TNF-alpha was 1.24 +/- 3.1 pg/mg total protein, and that of IL-1 beta was 18.79 pg/mg total protein. A strong, statistically significant correlation exists between the concentrations of endotoxin and TNF-alpha (r = .89) and IL-1 beta (r = .72). The data indicate that endotoxin may contribute to the pathogenesis of chronic otitis media with effusion by stimulating the sustained production of TNF-alpha and IL-1 beta in the middle ear.

    2016-01-01

    The upper respiratory tract (URT) hosts a complex microbial community of commensal microorganisms and potential pathogens. Analyzing the composition and nature of the healthy URT microbiota and how it changes over time will contribute to a better understanding of the pathogenesis of pneumonia and otitis. A longitudinal study was conducted including 174 Holstein calves that were divided in four groups: healthy calves, calves diagnosed with pneumonia, otitis or both diseases. Deep pharyngeal swabs were collected on days 3, 14, 28, and 35 of life, and next-generation sequencing of the 16S rRNA gene as well as quantitative PCR was performed. The URT of Holstein dairy calves aged 3 to 35 days revealed to host a highly diverse bacterial community. The relative abundances of the bacterial genera Mannheimia, Moraxella, and Mycoplasma were significantly higher in diseased versus healthy animals, and the total bacterial load of newborn calves at day 3 was higher for animals that developed pneumonia than for healthy animals. Our results corroborate the existing knowledge that species of Mannheimia and Mycoplasma are important pathogens in pneumonia and otitis. Furthermore, they suggest that species of Moraxella can potentially cause the same disorders (pneumonia and otitis), and that high neonatal bacterial load is a key contributor to the development of pneumonia.

  18. Association between adult otitis media and nasopharyngeal cancer: A nationwide population-based cohort study

    Purpose: To determine whether the diagnosis of otitis media (OM) in adults is associated with an increased risk for the subsequent development of nasopharyngeal cancer (NPC) using a nationwide population-based retrospective study. Methods and materials: We selected 13,513 adult patients that had been previously diagnosed with OM between 2000 and 2005 from the Taiwan Longitudinal Health Insurance Database 2000 as the study cohort, and randomly extracted the data of 135,130 participants matched by sex, age, and baseline year for the comparison cohort. The follow-up period was terminated upon developing NPC, withdrawal from the national health insurance system, or the end of 2009. Cumulative incidences and hazard ratios (HRs) of NPC development were determined. Results: The subsequent NPC incidence rates in the OM and comparison cohorts were 6.41 and 0.58 per 10 000 person-years, respectively (adjusted HR, 11.04; 95% CI, 7.68–5.87; P < 0.0001). The NPC risk for males was significantly higher than that for females (adjusted HR = 3.24; 95% CI, 2.16–4.85). In both female and male patients, the diagnosis of OM was associated with a significantly increased risk for NPC (adjusted HR, 11.91 vs. 10.78, respectively). Among the OM cohort, 62 participants were subsequently diagnosed with NPC, with 71% of them occurring within 1 year following the diagnosis of OM. However, even after 5-year follow-up, the OM cohort still displayed a higher risk for NPC (adjusted HR = 2.50). Stratified by the frequency of OM episodes, more than one episode per year had a significantly greater risk of developing NPC, compared with the comparison cohort (HR = 29.22; 95% CI, 20.19–42.27). Conclusion: We found that adult OM is a warning sign for the development of NPC in Taiwan, with approximately an 11-fold higher risk for adult OM patients. We recommend that OM patients undergo follow-up examinations for at least 5 years. To extrapolate our findings, further studies are warranted in other

    The objective of this study was to evaluate the role of group 3 innate lymphoid cells (ILC3) in the middle ear (ME) mucosal response to bacterial infection in a rat model. To confirm the role of ILC3 in bacterially induced otitis media (OM), the serum concentrations of IL-17 and IL-22 were determined by ELISA, and the tissue expression of IL-17 and IL-22 in infected ME mucosa was assessed by immunohistochemical staining. Immunohistochemical staining of specific cell surface markers was also assessed to confirm the origin of the cells expressing IL-17 and IL-22. Twenty Sprague-Dawley rats were used in the surgically-induced animal model of OM. OM was induced by inoculation of non-typeable Haemophilus influenzae into the ME cavity of the rats. The rats were divided into four experimental groups: three infected groups and one control group. Infected groups were subdivided into sets of 5 rats, one for each of the three time points (1, 4 and 7 days post-inoculation). For determination of rat IL-17 and IL-22 levels in infected rats and control rats, infected or control ME mucosa sections were analyzed by immunohistochemistry with specific antibodies directed against IL-17 and IL-22. Immunohistochemical staining for CD3, RORγt, and NKp46 were also conducted on the samples to confirm the origin of cells expressing IL-17 and IL-22. IL-17 and IL-22 serum concentrations were significantly increased in the infected rats compared to control rats. Immunohistochemical staining revealed increased IL-17 and IL-22 expressions in all infected ME mucosae from the first day after inoculation. In addition, the results of tissue staining for the specific surface markers were negative for CD3 and NKp46, but were highly positive for RORγt. IL-17 and IL-22 revealed their association with the bacterially induced proliferative and hyperplastic responses of ME mucosa, which are characteristic features in pathogenesis of OM. Surface marker examination showed that the source cells for IL-17

    Full Text Available BACKGROUND: Middle ear infection is one of the most common condition in ENT practice, particularly in our country. Its significance lies in its chronicity and its dreaded complications like hearing loss and cholesteatoma. Chronic suppurative Otitis media and its complications are among the most common conditions seen by both the otologist and pediatrician. Both gram positive and negative organisms are responsible for infection of the middle ear. AIMS: The study was primarily carried out in 200 cases of C.S.O.M. to determine the bacteriological flora and to study the antibiotic sensitivity pattern of the organisms isolated on culture from discharging ears. RESULTS: In our study Pseudomonas aeruginosa was found to be the most common isolated bacteria (40.65% [100/246], followed by Staphylococcus aureus (14.63%[36/246], Klebsiella aerogenes (11.78%[29/246] and Proteus Mirabilis (10.56%[26/246]. Among the anerobic organisms Peptostreptococcus (5.69% was the most common followed by Propionibacterium (4.06% and Bacteroids spp. (3.65%. Amikacin was the most effective antibiotic in the present study. It was effective against maximum number of strains 97(95.48% followed by Gentamycin 95(92.36% and Ciprofloxacin 93(91.30%. Cefoperazone 88(86.42%, Cefotaxime 78(74.54% and Ofloxacin 64(62.68%. CONCLUSION: Efficient and effective treatment of CSOM is based on the knowledge of causative micro-organisms and thus their antimicrobial sensitivity ensures proper clinical recovery and avoidance of the possible dreaded complications. It has been observed that human negligence is one of the main factor responsible for the development of antibiotic resistance. Along with the indiscriminate use of antibiotics by the treating physician the lack of compliance on part of the patient also results in emergence of resistance and thus in treatment failure.

    The hypertrophic adenoid may promote chronic suppurative otitis media in children as it fulfills its immune function. The number of lymphocytes in the adenoid and their cooperation in the immune response depend of on their proliferation and migration to the effector sites. Interleukin 7 (IL-7) is essential for the normal development and function lymphocytes. IL-7 plays pivotal role for activation and proliferation of T and B cells. The heterodimeric interleukin-7 receptor (IL-7R) is composed of the IL-7Rα (127) and the common cytokine receptor γc (CD132). The aim of this study was to evaluate the percentage of lymphocytes T (CD4(+) and CD8(+)) with IL-7R (CD127 and CD132) expression in hypertrophic adenoid in children suffering with otitis media with effusion for a duration of 3 months. Adenoid excised due to hypertrophy with or without chronic otitis media with effusion was used as study material. CD4(+) CD127(+), CD4(+)132(+), CD8(+)CD127(+) and CD8(+)CD132(+) cell subpopulations were identified using monoclonal antibodies and flow cytometry. The percentage of CD4(+) and CD8(+) T cells with CD127 receptor expression in hypertrophic adenoid of children with otitis media with effusion was statistically significantly higher than in hypertrophic adenoid group. The percentage of CD4(+) T cells with CD132 expression in the study group was statistically significantly higher than in the reference group. The percentage of CD8(+) T cells with CD132(+) expression was not statistically different in both groups. The increased percentage of T lymphocytes with IL-7R expression (CD127 and CD132) in hypertrophic adenoid seems to influence the quantity of lymphocytes and upset the immunological function of tonsils which can influence the course of otitis media with effusion.

    2008-04-01

    Full Text Available Abstract Background Otitis media (OM leads to significant reduction in the hearing sensitivity. The reduced auditory input, if in the early years of life when the auditory neural system is still maturing, may adversely influence the structural as well as functional development of the system. Past research has reported abnormalities in both the structure and function of brainstem nuclei following auditory deprivation, but, it has not necessarily focused on children who had OM in their first year of life. It can also be said that if auditory processing is affected at the brainstem level because of early onset OM (reduced auditory input in the crucial periods of neural development, then, it may be said that auditory processing is also affected at the cortical level because it receives distorted input from the brainstem. Therefore, the purpose of this study was to document the effects of early onset OM on auditory processing, if any, at the brainstem as well as at cortical levels. A related purpose of the study was to investigate the persistence of the effects of early onset OM, if any, on auditory processing. Methods A cross sectional approach and a standard group comparison design was used in the study. Thirty children, who had OM between 6 and 12 months of age and who were in the age range of 3.1 – 5.6 years participated in the study. Children with OM were divided into 3 groups based on their age. Click evoked auditory brainstem responses (ABRs and late latency responses (LLRs were recorded from these children, and the responses were compared with those from age and gender matched normal children without any history of OM. The data from the 2 groups was statistically analyzed through independent t test. Pearson's Product Moment correlation was computed to examine the relationship between results of ABR and LLR in children with early onset OM. Results The mean central conduction time was significantly increased and the mean amplitude of wave I

    2016-01-01

    Woakes' syndrome is characterised by severe recurrent nasal polyps in early childhood with broadening of the nose, nasal dyscrinia, frontal sinus aplasia and bronchiectasis. Eosinophilic otitis media (EOM) is an intractable condition that can cause gradual or sudden deterioration of hearing and is associated with comorbid asthma. For these reasons, both diseases must be recognised and treated appropriately. We present a case of a 20-year-old man with Woakes' syndrome complicated by EOM, with polyps in both middle ears; this condition has so far not been described as an entity of eosinophilic disease in the literature. We have, from reviewing the literature, learned that this is the first time that results of tissue examination on nasal polyposis with respect to tissue IgE, eosinophil-cationic protein, interleukin (IL)-17 and IL-5 in a patient with Woakes' syndrome and EOM, has been reported and discussed.

    Objective To investigate the effect of exogenous surfactant on Eustachian tube opening function. Methods This reasarch measures for the Eustachian tube opening pressure by injection of surface active substance into middle ear space, studying the effect of surfactant on Eustachian tube opening function. Results It has been showed that the injection of killed streptococcus pneumoneac bacteria by the transtympanic route, successfully developed a secretory otitis media model. Eustachian tube opening pressure in ears with SOM was significantly greater than those without effusion (P<0.01). Irrigation the middle ear space with surfactant resulted in a dramatic decrease in eustachian tube passive opening pressure in both normal and patients (P<0.01). Conclusion The results indicate that flushing with exogenous surfactant by the transtympanic rote reduce of eustachian tube surface tension, and it benefits the Eustachian tube opening.

  8. Tobacco smoke increases the risk of otitis media among Greenlandic Inuit children while exposure to organochlorines remain insignificant

    Jensen, Ramon Gordon; Koch, Anders; Homøe, Preben;

    2013-01-01

    BACKGROUND: Prenatal exposure to environmental levels of organochlorines (OCs) has been demonstrated to have immunotoxic effects in humans. We investigated the relationship between prenatal exposure to OCs and the occurrence of otitis media (OM) among Inuit children in Greenland. METHODS: We...... estimated the concentration of 14 PCB congeners and 11 pesticides in maternal and cord blood samples and in breast milk in a population-based cohort of 400 mother-child pairs. At follow-up, we examined the children's ears and used their medical records to assess the OM occurrence and severity. Multivariate...... regression analyses were used with adjustments for passive smoking, crowding, dietary habits, parent's educational level, breast feeding and the use of child-care. RESULTS: The children were 4-10years of age at follow-up and 223 (85%) participated. We found no association between prenatal OC exposure and the...

  9. Comparison between Microscopic and Endoscopic Approaches for Evaluation of Anatomic Areas in Surgically Treated Chronic Otitis Media

    M.T. Goodarzi

    2013-07-01

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

    2009-07-01

    Streptococcus pneumoniae is the most common pathogen associated with otitis media. To examine the role of Toll-like receptor 2 (TLR2) in host defense against Streptococcus pneumoniae infection in the middle ear, wild-type (WT; C57BL/6) and TLR2-deficient (TLR2(-/-)) mice were inoculated with Streptococcus pneumoniae (1 x 10(6) CFU) through the tympanic membrane. Nineteen of 37 TLR2(-/-) mice showed bacteremia and died within 3 days after the challenge, compared to only 4 of 32 WT mice that died. Of those that survived, more severe hearing loss in the TLR2(-/-) mice than in the WT mice was indicated by an elevation in auditory-evoked brain stem response thresholds at 3 or 7 days postinoculation. The histological pathology was characterized by effusion and tissue damage in the middle ear, and in the TLR2(-/-) mice, the outcome of infection became more severe at 7 days. At both 3 and 7 days postchallenge, the TLR2(-/-) mice had higher blood bacterial titers than the WT mice (P interleukin 1beta, MIP1alpha, Muc5ac, and Muc5b were significantly lower in the ears of TLR2(-/-) mice than in WT mice. In summary, TLR2(-/-) mice may produce relatively low levels of proinflammatory cytokines following pneumococcal challenge, thus hindering the clearance of bacteria from the middle ear and leading to sepsis and a high mortality rate. This study provides evidence that TLR2 is important in the molecular pathogenesis and host response to otitis media. PMID:19414550

    Full Text Available Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitivity profile of isolated organisms to commonly used antibiotics. Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR assays. Antibiotic susceptibility tests were also performed. Results: PCR analysis showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2% of the samples. The culture-positive effusion for Streptococcus Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin. Conclusion: Compared with other studies using PCR method, the number of H. influenza isolates was in higher in the present study (95.2%. Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical antibiotic therapy based on sensi-tivity profile in our geographic area.

    The purpose of the study is to assess the effect of a novel quorum sensing inhibitor (QSI), coded as 'yd 47', against otitis media and biofilm formation on Cochlear implants (CIs). Small pieces cut from cochlear implant were implanted under the skin in the retroauricular area on both sides of four guinea pigs. The implant pieces in the study and control sides were implanted in Streptococcus pneumoniae strain solution and saline, respectively. The right and left middle ears were also instilled with a solution containing pneumococci and saline, respectively. The animals were only given an intraperitoneal 'yd 47' twice daily for three months to be assessed later with electron microscopy. Clinical examination with palpation, inspection and otoscopy did not reveal any sign of implant infection or otitis media. In the study and control implant materials, soft tissues around the implant and tympanic membranes, there was no biofilm formation by pneumococci. Contamination by various cells and some rod-shaped bacteria (not diplococcic) were seen in some of the materials. In conclusion, the novel QSI seems promising in the prevention of otitis media and biofilm formation on CIs by pneumococci. PMID:24570174

    2015-01-01

    Full Text Available Objectives. Detection of extraesophageal reflux (EER in children with chronic otitis media with effusion (OME using three different diagnostic methods. Methods. Children between 1 and 7 years with OME who underwent adenoidectomy and myringotomy with insertion of a ventilation tube were included in this prospective study. EER was detected using three methods: oropharyngeal pH was monitored for 24 hours using the Restech system; detection of pepsin in middle ear fluid obtained during myringotomy was done using Peptest, and detection of pepsin in an adenoid specimen was done immunohistochemically. Results. Altogether 21 children were included in the study. Pathological oropharyngeal pH was confirmed in 13/21 (61.9% children. Pepsin in the middle ear fluid was present in 5/21 (23.8% children; these 5 patients were diagnosed with the most severe EER established through monitoring of oropharyngeal pH. No specimen of adenoids tested was positive for pepsin upon immunohistochemical examination. Conclusions. Diagnosis of EER in patients with OME using Restech is sensitive but less specific when compared to the detection of pepsin in middle ear fluid using Peptest. Pepsin in the middle ear was consistently present in patients with RYAN score above 200, and these patients in particular could potentially profit from antireflux therapy.

    OBJECTIVE: To estimate the impact of treatment with middle ear ventilation tube insertion (VTI) in children with otitis media (OM) on the risk of cholesteatoma on a national level. METHODS: Data were obtained from the Danish National Patient Register, the National Health Service Register and...... with STMEC1 at 12 years of age for children with 0, 1, 2, 3, and ≥4 VTI's was 0.04% (95% confidence interval 0.02-0.12%), 0.21% (0.18-0.26%), 0.35% (0.28-0.43%), 0.40% (0.30-0.54%), and 0.55% (0.44-0.70%), respectively. In the regression model each additional year of age before the first VTI increased...... underlying indication for VTI. In short the present study suggests that treatment with VTI in children with OM reduces the risk of STMEC1 on a population level. However, for the individual child the absolute risk reduction is very small, and the decision of treatment with VTI must always rely on the symptoms...

    1997-03-01

    In a study of the relationship between the prevalence of persistent otitis media with effusion (OME) in school entrant children in Redcar and Cleveland and the distance of the homes of these children from known industrial emission points, 1156 school entrant children were screened for the presence of persistent OME. The social disadvantage scores and map references were determined from the postcode area of each of the study entrants and map references were also obtained of known industrial emission points in the locality. Analyses were conducted on the association between the presence of OME and distance from emission sources and between the presence of OME and disadvantage score. A significantly greater proportion of study entrants with OME lived within 1000 meters of an industrial emission point than further away. However, there was no trend established between the proportion of study entrants with OME and increasing distance from an emissions source, nor was there any significant relationship established between the social disadvantage score of the areas of residence of the study entrants and the presence of OME. Further research is required to establish the effect of confounding variables on this relationship. PMID:9090283

  6. Tympanomastoidectomy: Comparison between canal wall-down and canal wall-up techniques in surgery for chronic otitis media

    Azevedo, Alexandre Fernandes de

    2014-01-01

    Full Text Available Introduction: Chronic otitis media (COM is an inflammatory condition associated with otorrhea as well as large and persistent perforations of the tympanic membrane in some cases. COM can also lead to cholesteatoma. Surgical treatment with canal wall-down and canal wall-up tympanomastoidectomy is considered for both types of illness. The choice of technique is controversial and is dependent on several factors, including the extent of disease. Objective: We aimed to evaluate surgical outcomes in COM patients with and without cholesteatoma treated with canal wall-down and canal wall-up tympanomastoidectomy. Disease eradication and post-operative auditory thresholds were assessed. Method: Patient records from the otorhinolaryngology department of a tertiary hospital were assessed retrospectively. Results: Patients who underwent canal wall-up tympanomastoidectomy had a higher rate of revision surgery, especially those with cholesteatoma. However, there were no statistically significant differences in post-operative hearing thresholds between the two techniques. Conclusion: The canal wall-down technique is superior to the canal wall-up technique, especially for patients with cholesteatoma.

    Full Text Available Predisposition to childhood otitis media (OM has a strong genetic component, with polymorphisms in innate immunity genes suspected to contribute to risk. Studies on several genes have been conducted, but most associations have failed to replicate in independent cohorts.We investigated 53 gene polymorphisms in a Finnish cohort of 624 cases and 778 controls. A positive association signal was followed up in a tagging approach and tested in an independent Finnish cohort of 205 cases, in a British cohort of 1269 trios, as well as in two cohorts from the United States (US; one with 403 families and the other with 100 cases and 104 controls.In the initial Finnish cohort, the SNP rs5030717 in the TLR4 gene region showed significant association (OR 1.33, P = .003 to OM. Tagging SNP analysis of the gene found rs1329060 (OR 1.33, P = .002 and rs1329057 (OR 1.29, P = .003 also to be associated. In the more severe phenotype the association was stronger. This finding was supported by an independent Finnish case cohort, but the associations failed to replicate in the British and US cohorts. In studies on TLR4 signaling in 20 study subjects, the three-marker risk haplotype correlated with a decreased TNFα secretion in myeloid dendritic cells.The TLR4 gene locus, regulating the innate immune response, influences the genetic predisposition to childhood OM in a subpopulation of patients. Environmental factors likely modulate the genetic components contributing to the risk of OM.

    2016-02-01

    Otitis media (OM) is a highly prevalent disease that can be caused by either a bacterial or viral infection. Because antibiotics are only effective against bacterial infections, blind use of antibiotics without definitive knowledge of the infectious agent, though commonly practiced, can lead to the problems of potential harmful side effects, wasteful misuse of medical resources, and the development of antimicrobial resistance. In this work, we investigate the feasibility of using a combined Raman scattering spectroscopy and low coherence interferometry (LCI) device to differentiate OM infections caused by viruses and bacteria and improve our diagnostic ability of OM. Raman spectroscopy, an established tool for molecular analysis of biological tissue, has been shown capable of identifying different bacterial species, although mostly based on fixed or dried sample cultures. LCI has been demonstrated recently as a promising tool for determining tympanic membrane (TM) thickness and the presence and thickness of middle-ear biofilm located behind the TM. We have developed a fiber-based ear insert that incorporates spatially-aligned Raman and LCI probes for point-of-care diagnosis of OM. As shown in human studies, the Raman probe provides molecular signatures of bacterial- and viral-infected OM and normal middle-ear cavities, and LCI helps to identify depth-resolved structural information as well as guide and monitor positioning of the Raman spectroscopy beam for relatively longer signal acquisition time. Differentiation of OM infections is determined by correlating in vivo Raman data collected from human subjects with the Raman features of different bacterial and viral species obtained from cultured samples.

    Full Text Available : INTRODUCTION: Chronic otitis media (COM is one among the commonest otological diseases encountered in otorhinolaryngological practice and attending ENT OPD especially among the lower socio-economic strata of society. AIMS: This study was carried out to know about the aerobic bacterial flora causing COM and in-vitro antibiotic susceptibility pattern in order to scientifically guide patient management instead of relying on empirical therapy alone. MATERIALS AND METHODS: This study included 100 patients of community acquired COM attending ENT OPD of a tertiary care level hospital. After proper sample collection by sterile aural swabs, they were immediately sent to the microbiology laboratory for processing by aerobic culture, isolation and identification following standard recommended methods and antibiotic susceptibility tests were done by Kirby-Bauer disc diffusion methods as per Clinical and Laboratory Standards Institute (CLSI guidelines. RESULTS: Out of 100 cases of COM, microbiological culture yielded 101 bacterial isolates from 90 patients and 4 fungal isolates (3 isolates of Candida albicans and 1 isolate of Aspergillusfumigatus from 4 patients. Polymicrobial infections were seen in 11.11% patients. In this study Staphylococcus aureus (31.68% was the commonest isolate followed by Pseudomonas aeruginosa (23.76%. Other common bacterial isolates were E.coli, Klebsiellapneumoniae, coagulase negative Staphylococcus (CONS, Proteus mirabilis in descending order. Piperacillin-tazobactum was the most sensitive drug (85.45% among the gram-negative bacteria followed by meropenem (81.81%, amikacin (76.36% and levofloxacin (74.54%. Gram positive bacteria showed 100% sensitivity to vancomycin and 93.47% sensitivity to linezolid. For Methicillin resistant Staphylococcus aureus (MRSA isolates ciprofloxacin, cotrimoxazole, tetracycline, linezolid and vancomycin were found to have good activity. CONCLUSION: This study suggests that the common etiological

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

  14. Comparison of Boric Acid and Combination Drug of Polymyxin, Neomycin and Hydrocortisone (polymyxin NH) in the Treatment of Acute Otitis Externa

    Introduction Acute otitis externa is an inflammation of the external auditory canal known as "swimmer’s ear". Direct costs including medical treatment, painkillers, antibiotics, steroids or both and indirect costs are also remarkable. Aim The aim of this study was to compare the effect of boric acid and polymyxin, neomycin and hydrocortisone composition in the treatment of acute otitis externa. Materials and Methods This randomized clinical trial was carried out on 80 patients aged more than 17-year-old who were referred to Kashani hospital clinic with a diagnosis of acute otitis externa by otolaryngologist. The patients were randomly allocated to two groups (A: Boric acid and B: polymyxin NH ear drops) and Painkiller was prescribed and administered orally for all patients and in the presence of fever, cellulitis around the ears and neck adenopathy, broad-spectrum systemic antibiotics were used besides topical treatment. Symptoms of patients who were evaluated by a physician includes pain, discharge from the ear, swelling of the ear canal, auricle swelling, tenderness, and ear itching. In addition, pain was evaluated in patients and was recorded by Macgill Pain Questionnaire, in the first, third, seventh and tenth days. Results Results showed that itching on third day (p=0.007) and swelling of the ear canal in the examination of the third day (p=0.006) and the seventh day (p=0.001) in the polymyxin NH group was more than those of boric acid group. Overall mean pain based on McGill questionnaire was 11.10±1.49 in boric acid group in the examination on the first day and was 4.05±0.22 in the examination on the tenth day and in the polymyxin NH group, it was 10.9±0.99 on the first day and 4.20±0.40 on the tenth day. In both groups, pain relief was the same and there was no significant difference between two groups (p=0.075). Conclusion The findings of this study showed slight differences in the effectiveness of the boric acid drug and combination of polymyxin

    The purpose of this study was to evaluate the expression of proinflammatory and immunoregulatory cytokines in chronic otitis media. The expression levels of TNF-α, IL-1α, IL-6 and IL-10 were determined by Western blot analysis of tissue samples obtained during ear surgery. The expression levels of TNF-α, IL-1α and IL-6 in cholesteatoma tissues were substantially higher compared to those determined in the granulation tissue. The highest levels of TNF-α, IL-1 and IL-6 proteins were observed in patients with bone destruction. There were no significant differences in the expression of IL-10 levels in cholesteatoma and normal skin, but in the granulation tissue its level was substantially higher. The level of IL-10 in cholesteatoma tissues inversely correlated with the expression of proinflammatory cytokines, the degree of bone destruction and cholesteatoma invasion. Increased expressions of TNF-α, IL-1α and IL-6 in chronic otitis media and a strong positive correlation between these cytokine levels and the degree of bone destruction indicate the destructive behavior of cholesteatoma or granulation tissue.

  18. Surface Proteins and Pneumolysin of Encapsulated and Nonencapsulated Streptococcus pneumoniae Mediate Virulence in a Chinchilla Model of Otitis Media

    Keller, Lance E.; Bradshaw, Jessica L.; Pipkins, Haley; McDaniel, Larry S.

    2016-01-01

    Streptococcus pneumoniae infections result in a range of human diseases and are responsible for almost one million deaths annually. Pneumococcal disease is mediated in part through surface structures and an anti-phagocytic capsule. Recent studies have shown that nonencapsulated S. pneumoniae (NESp) make up a significant portion of the pneumococcal population and are able to cause disease. NESp lack some common surface proteins expressed by encapsulated pneumococci, but express surface proteins unique to NESp. A chinchilla model of otitis media (OM) was used to determine the effect various pneumococcal mutations have on pathogenesis in both NESp and encapsulated pneumococci. Epithelial cell adhesion and invasion assays were used to examine the effects in relation to deletion of intrinsic genes or expression of novel genes. A mouse model of colonization was also utilized for comparison of various pneumococcal mutants. It was determined that pneumococcal surface protein K (PspK) and pneumolysin (Ply) affect NESp middle ear pathogenesis, but only PspK affected epithelial cell adhesion. Experiments in an OM model were done with encapsulated strains testing the importance of native virulence factors and treatment of OM. First, a triple deletion of the common virulence factors PspA, PspC, and Ply, (ΔPAC), from an encapsulated background abolished virulence in an OM model while a PspC mutant had detectable, but reduced amounts of recoverable bacteria compared to wildtype. Next, treatment of OM was effective when starting antibiotic treatment within 24 h with resolution by 48 h post-treatment. Expression of NESp-specific virulence factor PspK in an encapsulated strain has not been previously studied, and we showed significantly increased adhesion and invasion of human epithelial cells by pneumococci. Murine colonization was not significantly increased when an encapsulated strain expressed PspK, but colonization was increased when a capsule mutant expressed PspK. The

    Full Text Available Abstract Background Otitis media (OM is a very common condition in children and occurs during years that are critical to the development of learning, literacy, and math skills. Therefore, among a large cohort of Danish conscripts, we aimed to examine the association between hospitalisation with OM in early childhood and cognitive function and educational level in early adulthood. Methods We conducted a population-based prevalence study using linked data from healthcare databases and conscription records of Danish men born between 1977 and 1983. We identified all hospitalisations with OM before 8 years of age. Cognitive function was measured by the Boerge Prien validated group intelligence test (Danish Børge Prien Prøve, BPP. We adjusted for potential confounders with and without stratification by hearing impairment. Furthermore, we examined the association between hospitalisation with OM and the prevalence of having achieved a General Certificate of Secondary Education (GCSE, stratified by quartiles of BPP scores. Results Of the 18 412 eligible conscripts aged 18–25 years, 1000 (5.5% had been hospitalised with OM before age 8. Compared with conscripts without such a record, the adjusted prevalence ratio (PR for a BPP score in the bottom quartile was 1.20 (95% confidence interval [CI]: 1.09–1.33. There was no major difference in the proportion of men with a GCSE and those without among those hospitalised with OM in early childhood. For men in the bottom and upper quartiles of BPP scores, the PRs for early childhood hospitalisation with OM were 0.89 (95% CI: 0.59–1.33 and 0.96 (95% CI, 0.88–1.05, respectively. Among men with severe hearing impairment, the proportion with a BPP score in the bottom quartile did not differ between those with and without an OM hospitalisation [PR = 1.01 (95% CI: 0.78–1.34]. Conclusions Overall, we found that hospitalisation with OM in early childhood was associated with a slightly lower cognitive

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

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

    Full Text Available Streptococcus pneumoniae infections result in a range of human diseases and are responsible for almost one million deaths annually. Pneumococcal disease is mediated in part through surface structures and an anti-phagocytic capsule. Recent studies have shown that nonencapsulated Streptococcus pneumoniae (NESp make up a significant portion of the pneumococcal population and are able to cause disease. NESp lack some common surface proteins expressed by encapsulated pneumococci, but express surface proteins unique to NESp. A chinchilla model of otitis media (OM was used to determine the effect various pneumococcal mutations have on pathogenesis in both NESp and encapsulated pneumococci. Epithelial cell adhesion and invasion assays were used to examine the effects in relation to deletion of intrinsic genes or expression of novel genes. A mouse model of colonization was also utilized for comparison of various pneumococcal mutants. It was determined that pneumococcal surface protein K (PspK and pneumolysin (Ply affect NESp middle ear pathogenesis, but only PspK affected epithelial cell adhesion. Experiments in an OM model were done with encapsulated strains testing the importance of native virulence factors and treatment of OM. First, a triple deletion of the common virulence factors PspA, PspC, and Ply, (ΔPAC, from an encapsulated background abolished virulence in an OM model while a PspC mutant had detectable, but reduced amounts of recoverable bacteria compared to wildtype. Next, treatment of OM was effective when starting antibiotic treatment within 24 hrs with resolution by 48 hrs post treatment. Expression of NESp-specific virulence factor PspK in an encapsulated strain has not been previously studied, and we showed significantly increased adhesion and invasion of human epithelial cells by pneumococci. Murine colonization was not significantly increased when an encapsulated strain expressed PspK, but colonization was increased when a capsule

    1990-05-01

    The purpose of the study is to determine the incidence of beta-lactamase producing pathogens causing otitis media (O.M.) in the Emergency Room population of the University Pediatric Hospital. In our first four months of study, 22 patients, between the ages of 6 months to 13 y/o have been evaluated. Middle ear secretion cultures were obtained by tympanocentesis. The organisms recovered from cultures were S. epidermidis 3 (14%), S. pneumoniae 2 (9%) H. influenzae 1 (5%), mix flora 1 (5%) and 13 (59%) with no growth. None of these organisms were beta-lactamase producers. Up to 64% of the patients had history of 2 to 5 OM episodes during the last six months. Interesting is the association of bronchial asthma, sinusitis and allergy history with OM. Final study results will be presented in a near future. PMID:2375816

    Full Text Available Background/Aim. Secretory otitis media (SOM is a chronic, nonpurulent inflammation of the middle ear, characterized by a long-term presence of liquids of different density in the middle ear for at least three consecutive months, different degrees of hearing loss and the absence of perforation of the eardrum. The aim of this study was to estimate the early postoperative complications after insertion of tympanostomy tube (TT in children with secretory otitis media (SOM in an 18-month period after TT insertion. Methods. This retrospective study included children with SOM (n = 478, aged from 2.5 to 16 years, operated from 2000 to 2009. During these ten years 365 children had TT in both ears, 131 children had TT in one ear and 55 children were operated two or more times. Totally 843 ears were operated on. Date were obtained by regular fallow up in Out-patient clinic concerning symptoms reported by children and parents, otomicroscopy findings and hearing measurements (audiometry and tympanometry. Results. Transient otorrhea was the most common early postoperative complication (16.5%, then obstruction (9.5%, premature extrusion of TT (3.9%, chronic otorrhea (3.1%, granulation tissue (1.1% and medial displacement (0.5%. According to our experience gold and silicone TT were shown less successful than others. The incidence of premature extrusion of TT was significantly higher with gold TT, comparing to others (6/33, 18%; p < 0.001. We also found significantly more frequent medial displacement with silicone TT than with other ones (2/4, 50%; p < 0.001. Conclusion. There are many early postoperative complications of TT insertion, but they depend on the meticulous surgery techniques, regular postoperative examinations and the type of TT. The type of TT should be determined according to own experience.

    Streptococcus pneumoniae, a leading cause of otitis media (OM), undergoes spontaneous intra-strain variations in colony morphology. Transparent (T) variant is more efficient in colonizing the nasopharynx while the opaque (O) variant exhibits greater virulence during systemic infections. We hypothesized that changes in middle ear (ME) gas pressure/composition during Eustachian tube (ET) dysfunction and the treatment of that dysfunction, e.g., tympanostomy tube (TT) insertion, play a role in se...

  12. Acute renal failure caused by contrast media

    Acute renal complications occurring in response to intravascular administration of iodinated contrast media may remain restricted to clinically irrelevant, transient elevations of serum creatinine, but just as well manifest themselves in the form of severe oliguric renal failure giving rise to the need of life-long hemodialysis. It was the aim of this study to determine the frequency of those renal hazards by a) systematic screening of the literature for relevant cases and b) retrospective and prospective examination of patients chosen by the author. The mean frequency of incidents determined on the basis of data from the relevant literature was 5% for non-stratified populations. A separate analysis of no risk patients showed this to be as low as 0.5%. In a prospective study of 69 patients receiving the non-ionic contrast medium Iopamidol, for the purposes of phlebography, serum creatinine determinations carried out at 24 and 48 hours did in no case reveal increases exceeding 25%, even though 11 patients of this cohort were at a particular risk of developing renal complications. The remote possibility of nephrophaty occurring as a result of contrast medium administration could be further reduced by the use of non-ionic materials. (orig./GDG)

    2013-01-01

    Full Text Available Aims: To study the efficacy of mometasone furoate monohydrate topical nasal spray in the treatment of otitis media with effusion (OME in children aged between 4 and 15 years. Thus, by comparative analysis of results, at 0 and 6 weeks of using mometasone nasal spray, its efficacy in improving the clinical and audiological status of children with OME is assessed. Materials and Methods: A prospective, clinical study carried out on 22 children aged between 4 and 15 years who had attended our Department of Otolaryngology in a tertiary care hospital from January 2008 to May 2009. Results: The efficacy of mometasone furoate monohydrate topical nasal spray in the resolution of middle ear fluid in children aged between 4 and 15 years with OME in this study group was observed to be significant (52.7%. A significant improvement in the overall symptoms was seen in the treatment group. There was good improvement in the audiological status also. Conclusion: Topical steroids can be an alternative to surgery in controlling OME. However, these results are only short-term; a long-term follow-up is necessary. Topical intranasal mometasone furoate therapy can be considered a good therapeutic option to OME. Nasal administration of this steroid is safe, reproducible, easily performed, and well tolerated by pediatric patients.

    2012-12-01

    Full Text Available Abstract Background Streptococcus pneumoniae (Pnc, nontypeable Haemophilus influenzae (NTHi and Moraxella catarrhalis (Mcat are the most important bacterial pathogens associated with otitis media (OM. Previous studies have suggested that early upper respiratory tract (URT bacterial carriage may increase risk of subsequent OM. We investigated associations between early onset of URT bacterial carriage and subsequent diagnosis of OM in Aboriginal and non-Aboriginal children living in the Kalgoorlie-Boulder region located in a semi-arid zone of Western Australia. Methods Aboriginal and non-Aboriginal children who had nasopharyngeal aspirates collected at age 1-  Results Carriage rates of Pnc, NTHi and Mcat at age 1-  Conclusion Early NTHi carriage in Aboriginal children and Mcat in non-Aboriginal children is associated with increased risk of OM independent of environmental factors. In addition to addressing environmental risk factors for carriage such as overcrowding and exposure to environmental tobacco smoke, early administration of pneumococcal-Haemophilus influenzae D protein conjugate vaccine to reduce bacterial carriage in infants, may be beneficial for Aboriginal children; such an approach is currently being evaluated in Australia.

  15. Multiplex PCR to determine Streptococcus pneumoniae serotypes causing otitis media in the Republic of Ireland with further characterisation of antimicrobial susceptibilities and genotypes.

    Vickers, I

    2011-03-01

    The purpose of this study was to determine the serotypes, genotypes and antimicrobial susceptibilities of Streptococcus pneumoniae causing otitis media (OM) in children in Dublin, Ireland. S. pneumoniae isolates (n = 28) from spontaneously discharging OM were studied. Serotyping was performed using a previously undescribed multiplex polymerase chain reaction (PCR) scheme in combination with serological methods. Multilocus sequence typing (MLST) was performed using standard procedures. Antimicrobial susceptibility testing was performed using the Etest method. Fourteen different S. pneumoniae serotypes were identified. The five most common serotypes were 3, 19F, 19A, 14 and 6A, which accounted for 68% of all infections. The 7-valent pneumococcal conjugate vaccine (PCV7), 10-valent pneumococcal conjugate vaccine (PHiD-CV) and 13-valent pneumococcal conjugate vaccine (PCV13) provided potential coverages of 43%, 46% and 86%, respectively. Reduced susceptibility to penicillin was evident for 25% of isolates and was associated with serotypes 14, 19A, 19F and 9V. A total of 21 different sequence types (STs) were identified. Pneumococcal Molecular Epidemiology Network (PMEN) clones or their variants represented 54% (15\\/28) of all isolates. Continued monitoring and characterisation of S. pneumoniae causing OM in Ireland is warranted in order to guide future vaccine and treatment policies.

  16. Bone destruction mechanisms in chronic otitis media with cholesteatoma: specific production by cholesteatoma tissue in culture of bone-resorbing activity attributable to interleukin-1 alpha.

    Kurihara, A; Toshima, M; Yuasa, R; Takasaka, T

    1991-12-01

    To clarify specific mechanisms underlying cholesteatoma-induced bone destruction, surgical specimens of middle ear inflammatory granulation tissue with or without cholesteatoma were maintained in vitro and the bone-resorbing activity in their culture supernatants was analyzed by means of calcium release from mouse calvaria. Almost the same levels of bone-resorbing activity and prostaglandin (PG) E2 were found in the supernatants of both types of tissue. By contrast, aural polyp tissue yielded hardly any such activity or PGE2. Under the influence of indomethacin, however, only tissue with cholesteatoma produced considerable bone resorption activity, whereas PGE2 production was suppressed completely. Such activity in the cholesteatoma culture supernatant was not due to contamination of endotoxin and proved to be blocked by the introduction of anti-interleukin (IL)-1 alpha antibody into the calvarial assay system. Anti-IL-1 beta antibody had no effect on such activity. Interleukin-1 alpha was detected only in cholesteatoma tissue culture supernatants by means of enzyme-linked immunosorbent assay and by bioassay. These data suggest that the bone destruction in otitis media with cholesteatoma may be attributed to IL-1 alpha in addition to PGE2. PMID:1746847

    Mucin overproduction is a hallmark of otitis media (OM). Streptococcus pneumoniae is one of the most common bacterial pathogens causing OM. Mucin MUC5AC plays an important role in mucociliary clearance of bacterial pathogens. However, if uncontrolled, excessive mucus contributes significantly to conductive hearing loss. Currently, there is a lack of effective therapeutic agents that suppress mucus overproduction. In this study, we show that a currently existing antistroke drug, vinpocetine, a derivative of the alkaloid vincamine, inhibited S. pneumoniae–induced mucin MUC5AC upregulation in cultured middle ear epithelial cells and in the middle ear of mice. Moreover, vinpocetine inhibited MUC5AC upregulation by inhibiting the MAPK ERK pathway in an MKP-1–dependent manner. Importantly, ototopical administration of vinpocetine postinfection inhibited MUC5AC expression and middle ear inflammation induced by S. pneumoniae and reduced hearing loss and pneumococcal loads in a well-established mouse model of OM. Thus, these studies identified vinpocetine as a potential therapeutic agent for inhibiting mucus production in the pathogenesis of OM. PMID:25972475

    Full Text Available OBJETIVO: A incidência das otites médias em crianças tem aumentado consideravelmente nos últimos 20 anos. O objetivo deste trabalho foi revisar artigos sobre o impacto das otites médias sobre a aquisição da linguagem em crianças. FONTES DOS DADOS: Foram selecionados artigos catalogados na base Medline com os descritores otite média, linguagem, audição e criança. SÍNTESE DOS DADOS: A revisão de literatura mostrou que a perda auditiva observada nas otites médias pode ser resultante de: (1 alterações estruturais na orelha média, (2 lesões ultra-estruturais e anormalidades bioquímicas na cóclea, ou (3 alterações nas vias auditivas centrais. Cerca de 50% dos casos de otite média secretora, por exemplo, são acompanhados de perda auditiva leve e flutuante. Os dados de literatura apontam que os três primeiros anos de vida são críticos para o desenvolvimento da linguagem, e crianças com otites médias, nesse período, têm maior risco de apresentar distúrbios na aquisição da linguagem, no comportamento e, futuramente, no aprendizado escolar. CONCLUSÕES: As principais conseqüências das otites médias e da perda auditiva sobre a linguagem nessas crianças são erros fonéticos e de articulação da fala, bem como dificuldade para compreensão da leitura.OBJECTIVE: To review the literature concerning the impact of otitis media on language acquisitions in children. SOURCES OF DATA: Medline. The following keywords were used for searching: otitis media, hearing, language and children.

    Full Text Available Abstract Background Otitis media (OM is the most common paediatric illness for which antibiotics are prescribed. In Australian Aboriginal children OM is frequently asymptomatic and starts at a younger age, is more common and more likely to result in hearing loss than in non-Aboriginal children. Absent transient evoked otoacoustic emissions (TEOAEs may predict subsequent risk of OM. Methods 100 Aboriginal and 180 non-Aboriginal children in a semi-arid zone of Western Australia were followed regularly from birth to age 2 years. Tympanometry was conducted at routine field follow-up from age 3 months. Routine clinical examination by an ENT specialist was to be done 3 times and hearing assessment by an audiologist twice. TEOAEs were measured at ages Results At routine ENT specialist clinics, OM was detected in 55% of 184 examinations in Aboriginal children and 26% of 392 examinations in non-Aboriginal children; peak prevalence was 72% at age 5–9 months in Aboriginal children and 40% at 10–14 months in non-Aboriginal children. Moderate-severe hearing loss was present in 32% of 47 Aboriginal children and 7% of 120 non-Aboriginal children aged 12 months or more. TEOAE responses were present in 90% (46/51 of Aboriginal children and 99% (120/121 of non-Aboriginal children aged Overall prevalence of type B tympanograms at field follow-up was 50% (n = 78 in Aboriginal children and 20% (n = 95 in non-Aboriginal children. Conclusion The burden of middle ear disease is high in all children, but particularly in Aboriginal children, one-third of whom suffer from moderate-severe hearing loss. In view of the frequently silent nature of OM, every opportunity must be taken to screen for OM. Measurement of TEOAEs at age 1–2 months to identify children at risk of developing OM should be evaluated in a routine health service setting.

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

Of the 37 nodular shadows, there were 28 ones at the upper tympanum, 2 ones at the mesotympanum, and the remained 7 ones at the tympanic anlmm and aditus ad antrum. There were 27 ones of tympanic scute destruction, of which, 14 ones were accompanied by lateral wall destruction of the tympanum. 31 ones suffered from auditory ossicles transport, with 23 ones of bone destruction. There were 5 ones of petrosquamous lamina destruction. Conclusion The soft tissue shadows at the tympanum, mastoid sinuses and aditus ad antrum as well as ambient bone destruction can be the imaging diagnosis bases for the cholesteatoma.

  9. Spiral ligament fibrocyte-derived MCP-1/CCL2 contributes to inner ear inflammation secondary to nontypeable H. influenzae-induced otitis media

    2010-10-01

    Full Text Available Abstract Background Otitis media (OM, one of the most common pediatric infectious diseases, causes inner ear inflammation resulting in vertigo and sensorineural hearing loss. Previously, we showed that spiral ligament fibrocytes (SLFs recognize OM pathogens and up-regulate chemokines. Here, we aim to determine a key molecule derived from SLFs, contributing to OM-induced inner ear inflammation. Methods Live NTHI was injected into the murine middle ear through the tympanic membrane, and histological analysis was performed after harvesting the temporal bones. Migration assays were conducted using the conditioned medium of NTHI-exposed SLFs with and without inhibition of MCP-1/CCL2 and CCR2. qRT-PCR analysis was performed to demonstrate a compensatory up-regulation of alternative genes induced by the targeting of MCP-1/CCL2 or CCR2. Results Transtympanic inoculation of live NTHI developed serous and purulent labyrinthitis after clearance of OM. THP-1 cells actively migrated and invaded the extracellular matrix in response to the conditioned medium of NTHI-exposed SLFs. This migratory activity was markedly inhibited by the viral CC chemokine inhibitor and the deficiency of MCP-1/CCL2, indicating that MCP-1/CCL2 is a main attractant of THP-1 cells among the SLF-derived molecules. We further demonstrated that CCR2 deficiency inhibits migration of monocyte-like cells in response to NTHI-induced SLF-derived molecules. Immunolabeling showed an increase in MCP-1/CCL2 expression in the cochlear lateral wall of the NTHI-inoculated group. Contrary to the in vitro data, deficiency of MCP-1/CCL2 or CCR2 did not inhibit OM-induced inner ear inflammation in vivo. We demonstrated that targeting MCP-1/CCL2 enhances NTHI-induced up-regulation of MCP-2/CCL8 in SLFs and up-regulates the basal expression of CCR2 in the splenocytes. We also found that targeting CCR2 enhances NTHI-induced up-regulation of MCP-1/CCL2 in SLFs. Conclusions Taken together, we suggest that

  10. Differential diagnosis between chronic otitis media with and without cholesteatoma by temporal bone CT: focus on bone change and mass effect

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

    BACKGROUND Otitis media with effusion (OME) is a very common problem in primary care, but one that lacks an evidence-based non-surgical treatment. OBJECTIVE To determine the clinical effectiveness of nasal balloon autoinflation for the treatment of OME in children. DESIGN A pragmatic, two-arm, open randomised controlled trial. SETTING Forty-three general practices from 17 UK primary care trusts recruited between January 2012 and February 2013. PARTICIPANTS School children aged 4-11 years with a history of OME symptoms or related concerns in the previous 3 months, and a type B tympanogram, diagnostic of a middle ear effusion, in one or both ears. INTERVENTION Three hundred and twenty children were randomised, 160 to each group, using independent web-based computer-generated randomisation (with minimisation based on age, sex and baseline severity of OME) to either nasal balloon autoinflation performed three times per day for 1-3 months plus usual care, or usual care alone. MAIN OUTCOME MEASURES The proportion of children demonstrating clearance of middle ear fluid in at least one ear (with normal tympanograms) at 1 and 3 months, assessed blind to treatment. An ear-related measure of quality of life (QoL) [a 14-point questionnaire on the impact of OME (OMQ-14)], weekly diary recorded symptoms, compliance and adverse events were all secondary outcomes. RESULTS At 1 month, the proportion of children with normal tympanograms was 47.3% (62/131) in those allocated to autoinflation and 35.6% (47/132) in those receiving usual care [adjusted relative risk (RR) 1.36, 95% confidence interval (CI) 0.99 to 1.88]. At 3 months, the proportions were 49.6% (62/125) and 38.3% (46/120), respectively (adjusted RR 1.37, 95% CI 1.03 to 1.83; number needed to treat = 9). The change in OMQ-14 also favoured the intervention arm (adjusted global score difference -0.42; p = 0.001). Reported compliance was good: 89% in the first month and 80% in months 2 and 3. Adverse events included

  17. The management of otitis externa in UK general practice.

    Pabla, L; Jindal, M; Latif, K

    2012-03-01

    Acute otitis externa is common and provides a heavy workload for general practitioners. We aim to determine the first-line treatment used by general practitioners in the management of otitis externa and subsequent second-line treatment in a hospital ENT clinic. In addition, this study aims to ascertain whether local and national guidelines are being followed appropriately. A prospective observational study on the management of otitis externa in consecutive patients referred to an ENT emergency clinic was undertaken. Data were collected and analysed on symptoms, initial management by general practitioners, findings and treatment in the ENT clinic. A total of 106 patients were studied. The mean duration of symptoms before presentation to clinic was 13 days; 42% of patients received no treatment by their GP prior to referral to the ENT emergency clinic. Only 14% of patients received topical antibiotics alone, whilst 44% received oral antibiotics, either alone or in conjunction with topical antibiotics by their GP. Of the 106 patients, 86% received topical antibiotics in the ENT emergency clinic and oral antibiotics were reserved for those presenting with complicated acute otitis externa. Topical antibiotics are associated with a decrease in disease persistence, whilst oral antibiotics are associated with an increase. However, general practitioners are prescribing oral antibiotics more often than required. There are few regional guidelines and no explicit national guidelines on the management of acute otitis externa for GPs to refer to. We suggest the implementation of national guidelines to aid clinical practice. PMID:21761191

    2013-01-01

    The swimmer’s otitis or acute otitis externa, is a pathology that often occurs in those who practice swimming at a competitive level. The same problem often occurs in the summer with the attendance of swimming pools and bathing areas. A survey made in the United States in 2007 confirms the dynamics of the onset of this pathology, because the contamination of fungi and bacteria in the waters of the swimming pools and the sea cause the inflammation of the epithelium of the auditory canal.

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

    Nontypeable Haemophilus influenzae (NTHi) is associated with chronic otitis media (COM). In this study, we generated a murine model of COM by using eustachian tube (ET) obstruction and NTHi (10(7) CFU) inoculation into the tympanic bulla, and we investigated the relationship between regulatory T cells (Treg) and chronic inflammation in the middle ear. Middle ear effusions (MEEs) and middle ear mucosae (MEM) were collected at days 3 and 14 and at 1 and 2 months after inoculation. Untreated mice served as controls. MEEs were used for bacterial counts and to measure the concentrations of cytokines. MEM were collected for histological evaluation and flow cytometric analysis. Inflammation of the MEM was prolonged throughout this study, and the incidence of NTHi culture-positive MEE was 38% at 2 months after inoculation. The levels of interleukin-1β (IL-β), tumor necrosis factor alpha, IL-10, and transforming growth factor β were increased in the middle ear for up to 2 months after inoculation. CD4(+) CD25(+) FoxP3(+) Treg accumulated in the middle ear, and the percentage of Treg in the MEM increased for up to 2 months after inoculation. Treg depletion induced a 99.9% reduction of bacterial counts in MEEs and also significantly reduced the ratio of NTHi culture-positive MEE. The levels of these cytokines were also reduced in MEEs. In summary, we developed a murine model of COM, and our findings indicate that Treg confer infectious tolerance to NTHi in the middle ear. PMID:26553466

  2. Optimal management of acute nonrenal adverse reactions to iodine-based contrast media

    Full Text Available Yousef W Nielsen, Henrik S Thomsen Department of Radiology, Copenhagen University Hospital Herlev, Copenhagen, Denmark Abstract: Acute adverse reactions to iodine-based contrast media occur within 60 minutes of administration. The reactions range from mild (flushing, arm pain, nausea/vomiting, headache to moderate (bronchospasm, hypotension, and severe (cardiovascular collapse, laryngeal edema, convulsions, arrhythmias. Most acute adverse reactions occur in an unpredictable manner. Use of the older group of ionic iodine-based contrast agents increases the risk of acute adverse reactions. Other risk factors include previous reactions to contrast media, asthma, and allergic conditions. The exact pathophysiology of the acute adverse reactions is unknown, but some of the reactions are pseudoallergic mimicking type 1 allergic reactions. As antibodies against contrast media have not been consistently demonstrated, the reactions are, in most cases, not truly allergic in nature. Most of the severe and fatal adverse reactions occur within the first 20 minutes after injection. Thus, it is important that patients are observed in the radiology department during this period. The radiologist should be near the room where contrast media is administered, and be ready to treat any acute nonrenal adverse reaction. Appropriate drugs and resuscitation equipment should be in/near the room where the contrast media is administered. The important first-line management of acute adverse reactions includes the establishment of an adequate airway, oxygen supplementation by mask, intravenous fluid administration, and measurement of blood pressure and heart rate. When severe anaphylactoid reactions occur, adrenaline should be given intramuscularly. Only one concentration of adrenaline (1:1000–1 mg/mL should be available in the radiology department to avoid dosing errors in stressful acute settings. Resuscitation team specialists should be the only ones giving intravenous

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

  10. Media's role in broadcasting acute stress following the Boston Marathon bombings.

    Holman, E Alison; Garfin, Dana Rose; Silver, Roxane Cohen

    2014-01-01

    We compared the impact of media vs. direct exposure on acute stress response to collective trauma. We conducted an Internet-based survey following the Boston Marathon bombings between April 29 and May 13, 2013, with representative samples of residents from Boston (n = 846), New York City (n = 941), and the remainder of the United States (n = 2,888). Acute stress symptom scores were comparable in Boston and New York [regression coefficient (b) = 0.43; SE = 1.42; 95% confidence interval (CI), -2.36, 3.23], but lower nationwide when compared with Boston (b = -2.21; SE = 1.07; 95% CI, -4.31, -0.12). Adjusting for prebombing mental health (collected prospectively), demographics, and prior collective stress exposure, six or more daily hours of bombing-related media exposure in the week after the bombings was associated with higher acute stress than direct exposure to the bombings (continuous acute stress symptom total: media exposure b = 15.61 vs. direct exposure b = 5.69). Controlling for prospectively collected prebombing television-watching habits did not change the findings. In adjusted models, direct exposure to the 9/11 terrorist attacks and the Sandy Hook School shootings were both significantly associated with bombing-related acute stress; Superstorm Sandy exposure wasn't. Prior exposure to similar and/or violent events may render some individuals vulnerable to the negative effects of collective traumas. Repeatedly engaging with trauma-related media content for several hours daily shortly after collective trauma may prolong acute stress experiences and promote substantial stress-related symptomatology. Mass media may become a conduit that spreads negative consequences of community trauma beyond directly affected communities. PMID:24324161

  16. Fusobacterium necrophorum otitis and mastoiditis in infants and young toddlers.

    Stergiopoulou, T; Walsh, T J

    2016-05-01

    There is an increased recovery of Fusobacterium necrophorum from cases of otitis media and mastoiditis in the pediatric population. These infections may be highly severe, causing local osteomyelitis, bacteremia, and Lemierre's syndrome. The severity and difficulties in providing optimal treatment for these infections may be especially difficult in this age group due to immunological immaturity and delayed presentation. In this review of literature, we present and analyze the clinical presentation, management, and outcome of otic infections caused by F. necrophorum in infants and young toddlers less than 2 years old. Search in Pubmed was conducted for reported cases in the English literature for the time period of the last 50 years. Twelve well-described cases were retrieved with F. necrophorum otitis and mastoiditis and complications reported in all cases. Treatment included both intravenously with antimicrobial agents (beta lactams plus metronidazole) and mastoidectomy. Lemierre's syndrome and Lemierre's syndrome variants developed in 60 % of the patients. Dissemination of the infection as distal osteomyelitis and septic shock were also reported. The outcome was favorable in all the cases. Otitis and mastoiditis infections in children less then 2 years old are invasive infections, and severe complications can occur. PMID:26951264

    2006-05-01

    The objective of this study was to evaluate the clinical safety of intravenous gadolinium-based contrast media used in patients who underwent MRI at a single institution. Acute adverse reactions to intravenous gadolinium-based contrast media used for MRI at the Princess Margaret Hospital, Hong Kong, SAR, from January 1999 to November 2004 were recorded in an incidence log book. The medical records of patients' demographics were retrospectively reviewed and the nature, frequency and severity of the adverse reactions were investigated and documented. The incidence of acute adverse reactions to intravenous gadolinium-based contrast media was 0.48% (45 patients with 46 adverse reactions). The severity of these adverse reactions were 96% mild, 2% moderate (one patient developed shortness of breath that required oxygen supplementation and intravenous steroidal management) and 2% severe (one patient developed an anaphylactoid reaction, but successfully recovered through timely resuscitation). No patients were recorded as having contrast extravasation and none died as a result of any adverse reaction. Among the 45 patients who developed adverse reactions, three patients (6.7%) had prior adverse reactions to iodinated contrast media, three (6.7%) had prior reactions to a different gadolinium-based contrast agent, one (2%) had asthma and nine (20%) had a history of drug/food allergy. Overall, 41% of the adverse reactions were not documented in the final MRI report or the clinical medical records. Gadolinium-based contrast media are safe and well tolerated by the vast majority of patients. In our study, the adverse reaction rate (0.48%) and the incidence of severe anaphylactoid reaction (0.01%) concur with those reported in the literature. Although most of the symptoms are mild and transient, these adverse reactions must be accurately documented and managed. PMID:16632615

    Full Text Available Introducción: La Patología infecciosa del oído externo es relativamente frecuente en niños pequeños y en algunas ocasiones presentándose como una alteración de la articulación temporomandibular. Sin embargo, la patología aguda de esta articulación es muy poco frecuente en esta edad de la vida. Si existe, habitualmente es precedida por un episodio de traumatismo. Una adecuada anamnesis y exploración física suele resultar en un diagnostico acertado sin realizar pruebas complementarias adicionales. Materiales y métodos: Presentamos tres casos clínicos derivados al Servicio Pediátrico de Cirugía Oral y Maxilofacial del Hospital Universitario La Paz con el diagnóstico de patología ATM aguda. El diagnóstico final en los tres casos fue otitis externa aguda (OEA. Discusión: La OEA es la segunda causa mas frecuente de otalgia después de la otitis media aguda. La humedad, los traumas repetidos y la obstrucción glandular pueden promover la infección. Los síntomas incluyen dolor, prurito, supuración y en ocasiones pérdida auditiva. En ocasiones el movimiento mandibular sin maloclusión es doloroso. Este síntoma puede causar confusión e inducir a un diagnóstico erróneo de patología articular, lo cual es muy poco frecuente en niños. La patología de ATM en niños se caracteriza por dolor durante la apertura oral asociando disoclusión. Una correcta otoscopia permitirá realizar el diagnostico diferencial entre ambas entidades y evitar exploraciones radiológicas innecesarias. Conclusión: Debido a la poco frecuente presentación de patología ATM en niños pequeños, la OEA debe ser descartada antes de someter al paciente a exámenes radiológicos complementarios.Introduction: Infectious pathology of the external ear is quite frequent in small children and sometimes appears as an alteration of the temporomandibular joint function. However, acute pathology of this joint is quite rare in this age group and is nearly always

    2010-12-01

    Full Text Available The therapeutic effects of Argentine propolis ear drop formulation on canine otitis externa were evaluated. Forty-eight dogs with symptoms of otitis externa were randomly assigned to double-blinded, controlled clinical trial to evaluate the efficacy of topical formulation with propolis versus a topical placebo in the treatment of otitis externa. The propolis preparation and placebo were administrated into both external ear canals, twice daily for 14 days. Throughout the study, clinical examination and microbiological analysis of dogs ear exudates were made. The most frequent microorganisms isolated in culture media were: Malassezia pachydermatis (54.2%, Staphylococcus aureus (43.8%, coagulase-negative Staphylococcus (25.0%, Pseudomonas aeruginosa (20.8%, Candida albicans (18.8%, Proteus mirabilis (16.7%, Streptococcus spp. (16.7%, Enteroccocus faecalis (12.5%, Escherichia coli (12.5%, Staphylococcus intermedius (6.3%, Klebsiella spp. (4.2%, andCandida glabrata (2.1%. Whereas the control group did not recover from the infectious ear disease, the propolis preparation exhibited antimicrobial activity against most of the microorganisms isolated from samples of the treated group. In addition, no propolis-adverse effects were observed. This allowed propolis-treated patients to show a significant improvement of the clinical parameters. Thus, this new Argentine propolis ear drop formulation may be used for topical treatment of otitis externa in dogs.

    Full Text Available At the beginning of 2005, an outbreak of ceruminous otitis has been observed in a breeders flock belonging to the Robusta Lionata breed, a native chicken breed reared in a Centre for the valorisation and conservation of native poultry breeds. The disease caused a high morbidity rate (90% of birds, whereas the mortality affected only 10% of the birds. The death of the birds was preceded by clinical signs, such as worsening of the ceruminous otitis with abundant secretion of bad-smelling cerumen, lack of appetite and depression. The otitis externa, mainly bilateral, was the only evident finding at necropsy. Laboratory examinations showed only the presence of Mycoplasma synoviae, either by isolation on culture media or by PCR, on ear and choana samples. Aspergillus fumigatus was detected only in one bird. In this paper, the Authors report for the first time on an outbreak of ceruminous otitis in native chicken breeds and point out that the only pathogenic agent isolated from the birds has been Mycoplasma synoviae.

    2002-01-01

    Full Text Available Background: Distance education methods have taken on greater importance as medical student education has moved off campus into the community. What the best methods are for conveying information to students at distant sites has not been determined. Objective: To determine if students at distant community sites who received an otitis media study case by e-mail that was enhanced with a referral to a web-based otitis study case, performed better on otitis OSCE stations than students who received the same case not enhanced with visuals or referrals to a web-based otitis case. Design/Methods: Students were randomized by community site to receive either the enhanced (E or simple otitis study case (S. Students were e-mailed an otitis media study case during the 5th week of the rotation. Those randomized to the E-case received a case that started with a case scenario followed by a "Task" that instructed them to go to this web address: http://www.aap.org/otitismedia/www/vc/ear/index.cfm (American Academy of Pediatrics Otitis Web Site. They were then to select "Case 1" which was a continuation of the case scenario present on their e-mail. A list of learning objectives was also printed on the e-mail. Students receiving the S-case viewed the same case scenario and objectives, but were not instructed to go to the web page. All students rotated through two OSCE otitis stations. In the first station they interviewed a simulated patient(OSCE-SP and counseled her on the management of her 12 month old with otitis. Within that station they viewed a video of a pneumoscopic exam of two ears, one ear with otitis and the other ear normal. At the 2nd otitis station the student presented the case to a faculty and was asked a series of questions about otitis media(OSCE-PR. Scores on the two stations were compared by group. Results: There were 198 students who took the OSCE. 178 (90% responded to a survey that indicated they had opened and read the e-mailed case. There

    2003-08-01

    Full Text Available O uso do tubo de ventilação (TV da orelha média, tratamento cirúrgico eleito da otite média com efusão (OME, não é isento de complicações, promovendo ainda limitação social pela necessidade de abandono dos banhos de imersão. A mitomicina C (MMC é um antineoblástico, cuja aplicação tópica retarda a fibrose e previne a estenose cicatricial. Em cobaias, retardou o fechamento de timpanotomias, permitindo maior tempo de aeração da orelha média, à semelhança dos tubos de ventilação. FORMA DE ESTUDO: Clínico prospectivo. OBJETIVO: Comparar a eficácia entre timpanotomia, aspirado da efusão e inserção de tubo de ventilação (grupo TV versus timpanotomia, aspirado da efusão e aplicação tópica de mitomicina C (grupo MMC. Comparar o tempo de manutenção da timpanotomia e a incidência de complicações nos dois grupos. RESULTADOS: O grupo MMC apresentou eficácia significativamente menor (52% versus 80% que o grupo TV (p= 0,34. A presença de timpanometria tipo "B" e a ausência de comprometimento do óstio faríngeo tubário pelo tecido adenóide no pré-operatório representaram fatores de mau prognóstico. A aplicação tópica de MMC nas bordas da timpanotomia proporcionou um tempo de abertura da membrana timpânica por duas a três semanas. No grupo TV, a otorréia foi observada em 13,3% dos pacientes. No grupo MMC, apesar da menor eficácia, nenhum paciente apresentou complicações nem sofreu prolongada proibição dos banhos de imersão. CONCLUSÃO: Apesar de concluirmos que o TV apresenta maior eficácia, novos estudos utilizando maior concentração, maior tempo de aplicação ou o uso seriado de MMC no tratamento da otite média com efusão devem ser realizados.The insertion of the ventilation tube (VT, which is the surgical treatment for otitis media with effusion (OME, is not free from complications and also limits social life because of the need of abandoning immersion baths.

  17. Malignant otitis externa: An Australian case series.

    2012-02-01

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

    2008-07-01

    A 28-year-old female patient with a migrant background presented for surgery with a suspected cholesteatoma in the left ear. The patient reported having had an aural discharge for several months; otoscopic examination revealed a runny ear, and discrete granulation tissue was seen. Pure-tone audiometry showed conduction hearing loss of 30-40 dB across all frequencies in the left ear; high-resolution computed tomography of the temporal bone revealed that the mastoid and tympanic cavity were completely obscured. The intraoperative finding showed a caseous space-occupying mass that completely filled the tympanic cavity. The suspected diagnosis of tuberculosis was corroborated by pathohistological, microbiological and molecular biological tests. Tuberculostatic therapy was initiated at a different location. Although tuberculosis of the middle ear is a rare condition in Germany, it should nevertheless be considered when making a differential diagnosis, especially in high-risk patients where cholesteatoma is suspected on clinical and radiological evidence or in patients with a chronic middle ear process.

A systematic review of clinical trials and cohort studies was conducted, in which the effects child day-care attendance had on the health of young children based on the Cochrane Collaboration, PubMed and Spanish Medical Index databases, without any time or language-related limits, were analyzed and rounded out with analyses of referenced works and an additional EMBASE search. The methodological quality was evaluated by means of personalized criteria. Pooling measures (relative risks, incidence density ratios and weighted mean differences) were calculated with their confidence intervals, assuming random effects models. A significant increase was found to exist of a risk consistent over time and among different social and geographical environments. Considering the most methodologically-stringent studies with adjusted effect estimates, child day-care attendance was related to an increased risk of upper respiratory tract infection (RR=1,88), acute otitis media (RR=1,58), otitis media with fluid draining (RR=2,43), lower respiratory tract infections (overall RR=210; acute pneumonia RR=1.70; broncholitis RR=1,80; bronchitis RR=2,10) and gastroenteritis (RR=1,40). Child day-care attendance could be responsible for 33%-50% of the episodes of respiratory infection and gastroenteritis among the exposed population. In conclusion, it can be said that the risk for childhood health attributable to the child day-care attendance is discreet but of high-impact. This information has some major implications for research, clinical practice, healthcare authorities and society as a whole. PMID:17639680

    1995-06-01

    In both patients and experimental animals, immunoglobulin G (IgG) has been found to dominate acute otitis media with effusion (OME), whereas IgA tends to be present in chronic but not in acute OME. To determine whether local immunoregulation could account for this difference, the expression of cytokines associated with the production of different antibody isotypes was investigated in experimental acute and chronic OME. Mice were systemically immunized and then challenged transtympanically, once to produce an acute OME or once per week for 6 weeks to produce chronic OME. Hybridization with molecular probes for cytokine genes showed that cells producing interleukin-2 (IL-2) and IL-4, but not IL-5, were present during acute OME. In chronic OME, IL-2-positive (IL-2+) and IL-4+ cells were less prevalent, but IL-5+ cells were numerous. These finding support a model by which locally produced IL-2 and IL-4 augment IgG production in acute OME, whereas, IL-5 contributes to increased IgA production in chronic OME. PMID:7769948

  5. Quantitative bone and 67Ga scintigraphy in the differentiation of necrotizing external otitis from severe external otitis

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

  6. Preliminary results on scintigraphic evaluation of malignant external otitis

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

    Millions of people witnessed early, repeated television coverage of the September 11 (9/11), 2001, terrorist attacks and were subsequently exposed to graphic media images of the Iraq War. In the present study, we examined psychological- and physical-health impacts of exposure to these collective traumas. A U.S. national sample (N = 2,189) completed Web-based surveys 1 to 3 weeks after 9/11; a subsample (n = 1,322) also completed surveys at the initiation of the Iraq War. These surveys measured media exposure and acute stress responses. Posttraumatic stress symptoms related to 9/11 and physician-diagnosed health ailments were assessed annually for 3 years. Early 9/11- and Iraq War-related television exposure and frequency of exposure to war images predicted increased posttraumatic stress symptoms 2 to 3 years after 9/11. Exposure to 4 or more hr daily of early 9/11-related television and cumulative acute stress predicted increased incidence of health ailments 2 to 3 years later. These findings suggest that exposure to graphic media images may result in physical and psychological effects previously assumed to require direct trauma exposure. PMID:23907546

    We report the case of an immunocompromised female patient with external otitis, who developed a picture of external otitis with poor response to conventional treatment and subsequent isolation of Pseudomona Aeruginosa in the ear secretion culture. The final diagnosis was malignant external otitis. Our objective is to describe the scintigraphic findings as well as to analyze their correlation with the clinical pattern and to evaluate the possible causes of the discordance found. PMID:23067529

    Eighty further case-reports of patients, hospitalized for particularly severe forms of cholesteatomatous chronic otitis since 1977, are analyzed. -Cholesteatomas were associated with spontaneous atticotomy and atrial invasion in 37 cases, while in 8 patients the cholesteatoma was revealed by the presence of premalleal and anterior subligamental perforations. -New features were observed in 7 cases of cholesteatomatous and osteomatous chronic otitis. -Giant cholesteatoma was present in 12 cases, and unilateral tumors in 6 patients. -Four rarer types of lesion, obviously of a serious nature, were observed, including: -polypoid and hemorrhagic tumors (6 cases), -persistently highly fetid cholesteatomas (6 cases), and those that appeared to be "under pressure" (13 cases). -Finally, 7 cases were unusual and disturbing, demonstrating early extensive osteitic recurrence less than 6 months after initial excision. Widespread evidement is necessary for the majority of these cases. PMID:7103344

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

  12. Acute adverse reactions to radiographic iodinated and gadolinium-based contrast media: incidence, risk factors and premedication: from published evidence to a practical approach.

    Tonolini, M; Bianco, R

    2011-01-01

    Although relatively uncommon especially in their severe manifestations, adverse reactions (ARs) to radiographic contrast media (CM) may represent a source of concern to both physicians and patients because of the large number of CT and MR imaging procedures daily performed. In this paper the current literature is reviewed regarding incidence and risk factors for acute ARs to both iodinated and gadolinium-based CM, and about the usefulness of pharmacological premedication to reduce risk. A practical approach for everyday clinical practice is proposed. PMID:22262334

    2002-07-01

    Full Text Available Chronic otitis media and mastoiditis is a common otologic condition. Although it does not occur as frequently as acute otitis media, but remains a persistent and perplexing problem. Nowadays, although with improved access to medical care , advanced technology of imaging and entrance of new powerful antimicrobials, dangerous and deathful complications of c.o.m have become less common significantly, but unfortunately more of less serious complications is seen continuously."nMaterials and Methods: A retrospective study of 1500 patients with C.O.M that had been operated during the years 1991 - 97 in Amir hospital was conducted."nResults: patients had ages between 8 months to 78 years old with a peak incidence at 3rd decade of life. Among that patients, 56 patients (3.7 percent had one of major C.O.M complications. Over ally, in order of frequency, we found: facial nerve paralysis 27 pt (1.8 percent labyrinthitis and perilymphatic fistula 16 pt (1.06 percent Intracranial abscess 5 pt (0.33 percent, lateral sinus thrombosis 4 pt (0.26 percent Meningitis 2 pt (0.13 percent and Bezold's abscess 2 pt (0.13 percent peak - age incidence of complications was 3rd decade of life and M/F incidence of complications was 3/2."nConclusion: The early diagnosis and treatment of C.O.M complications are very important (specially intracranial complications, but it can be possible if the physician thinks about it.

    2016-08-01

    A healthy 60-year-old male was initially treated for external otitis, and subsequently received multiple surgeries including abscess drainage, temporal bone debridement, canaloplasty of the external auditory meatus, and fistula excision and was treated with numerous antibiotics at another hospital over a 1-year period. He was seen at our hospital on February 14, 2014 with a complaint of a non-healing wound behind the left ear and drainage of purulent fluid. He had no history of diabetes mellitus or compromised immune function. Computed tomography (CT) and magnetic resonance imaging (MRI) studies at our hospital showed osteomyelitis involving the left temporal, occipital, and sphenoid bones, the mandible, and an epidural abscess. Routine blood testing and tests of immune function were normal, and no evidence of other infectious processes was found. He was diagnosed with malignant otitis externa (MOE). Bone debridement and incision and drainage of the epidural abscess were performed, and vancomycin was administered because culture results revealed Corynebacterium jeikeium, Corynebacterium xerosis, and Enterococcus faecalis. MOE should be considered in healthy patients with external otitis who fail initial treatment. PMID:26233245

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

    2016-01-01

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

  18. Nuclear scanning in necrotizing progressive ''malignant'' external otitis

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

  19. Malignant external otitis: The diagnostic value of bone scintigraphy

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

    2006-01-01

    Full Text Available Malignant otitis externa (MOE is a severe infection of external auditory canal and skull base. A 17-year-old diabetic girl was admitted with diabetic ketoacidosis. Cellulitis of her right ear occurred on the second day of hospitalization and a black necrotic scar in the same region appeared on the next day. The lesion rapidly invaded to right side of neck and surrounding tissue of the patient. Therefore, antimycotic therapy was started. Unfortunately the patient died on seventh day of hospitalization because of probably extensive fungal invasion. Physicians should suspect MOE connected to mucormycosis especially in patients with cutaneous lesions of ear unresponsive to antibiotic therapy.

  1. STUDY OF CAROTID INTIMA MEDIA THICKNESS IN PATIENTS WITH ACUTE ISCHEMIC STROKE AND ITS CORRELATION WITH RISK FACTORS OF ISCHEMIC STROKE - A CASE CONTROL STUDY

    2013-10-01

    Full Text Available ABSTRACT: Stroke is the leading cause of mortality worldwide. Carotid Intima Media Thickness (CIMT is a marker of atherosclerosis and is also a marker for ischemic stroke. AIMS: 1 To assess the value of carotid intima media thickness at which patients with risk factors can develop acute ischemic stroke. 2 To correlate carotid intima media thickness with risk factors of acute ischemic stroke. MATERIAL & METHODS: This study was done at KIMS Hospital, Bangalore between December 2010 to September 2012. This is a case control observational study which has a sample size of 50 cases and 50 controls. Method of collection of data was by patient evaluation which was done by taking detailed history, clinical examination and laboratory investigations throu gh a proforma specially designed for this study. Cases were subjects who had ischemic stoke and Infarct proven by CT/MRI of brain, Controls were subjects without stroke matched to cases by age, gender and risk factors like diabetes, hypertension, smoking a nd dyslipidemia. S ubjects in both groups underwent carotid Doppler investigation with 7.5 Mhz linear superficial array probe to determine CIMT and presence of plaques. RESULTS: Out of 50 cases, 46 had CIMT between 0.06 - 0.20 cm [92%] and out of 50 controls, 45 had CIMT between 0.06 - 0.20 cm[90%]. Most of our cases had CIMT above 0.06 cm, so we can hypothesize that people with risk factors having CIMT above 0.06 cm are more prone for ischemic cerebro vascular accidents. Mean CIMT in cases with risk factors is significantly increased when compared to controls with risk factors. CONCLUSION: People with risk factors [ age > 50 years, DM , HTN , Smoking and Dyslipidemia] having CIMT above 0.06 cm are more prone for ischemic CVA, so people with risk factors should u ndergo screening for CIMT measurement by Carotid Doppler which is non invasive and cost effective and if their CIMT is above 0.06 cm they should undergo early medical intervention to take care

  2. Malignant otitis externa with bilateral cranial nerve involvement: Report of a unique case

    Somnath Saha

    2013-01-01

    Full Text Available Malignant otitis externa is an inflammatory condition caused by pseudomonas infection usually in the elderly diabetics, or an immunosuppressive condition that presents with diffuse otitis externa along with excruciating pain and granulations tissue in the external auditory meatus. Facial paralysis is common along with occasional involvement of other cranial nerves. Case report describing a patient of malignant otitis externa who presented to a tertiary referral hospital of eastern India. This patient had ipsilateral facial and tenth cranial nerve paralysis along with delayed-onset contralateral sixth and twelfth cranial nerve palsy. The patient was treated initially with intravenous anti-pseudomonal antibody followed by tympanic platectomy, facial nerve decompression and medialisation thyroplasty. The contralateral cranial nerve palsy was managed conservatively with partial recovery of function. Malignant otitis externa, though a common disease, may occasionally present with uncommon or unexplained presentations. The management of these cases should be prompt and aggressive and specifically address each of the debilitating complications.

    In malignant external otitis (MEO), determining the anatomic extent of disease and evaluating the physiologic response to therapy remain a problem. Magnetic resonance imaging (MRI) has recently become available in limited clinical settings. Four patients with MEO were evaluated using MRI, computerized tomography (CT), technetium-99 (Tc-99) bone scanning, and gallium-67 citrate (Ga-67 citrate) scanning. MRI is superior to CT, Tc-99 bone scanning, and Ga-67 citrate scanning in evaluating the anatomic extent of soft tissue changes in MEO. MRI alone cannot be relied upon to determine the physiologic response to therapy. MRI can, however, serve as a valuable guide to the interpretation of Tc-99 bone and Ga-67 citrate scans, and in this respect, MRI is extremely useful in the treatment of MEO.

    Recent evidence demonstrates that individuals with low heart rate (HR) reactions to acute psychological stress are more likely to be obese or smokers. Smoking and obesity are established risk factors for increased carotid intima-media thickness (IMT). The aim of this study was to examine the potential pathways linking intima-media thickness, smoking, body mass index (BMI), and HR stress reactivity. A total of 552 participants, 47.6% male, M (SD) age = 58.3 (0.94) years, were exposed to three psychological stress tasks (Stroop, mirror drawing, and speech) preceded by a resting baseline period; HR was recorded throughout. HR reactivity was calculated as the average response across the three tasks minus average baseline HR. Smoking status, BMI, and IMT were determined by trained personnel. Controlling for important covariates (e.g., socioeconomic status), structural equation modeling revealed that BMI and smoking mediated the negative relationship between HR reactivity and IMT. The hypothesized model demonstrated a good overall fit to the data, χ(2) (8) = 0.692, p = .403; CFI = 1.00; TLI = 1.00 SRMR = .01; RMSEA < .001 (90% CI < 0.01-0.11). HR reactivity was negatively related to BMI (β = -.16) and smoking (β = -.18), and these in turn were positively associated with IMT (BMI: β = .10; smoking: β = .17). Diminished HR stress reactivity appears to be a marker for enlarged IMT and appears to be exerting its impact through already established risks. Future research should examine this relationship longitudinally and aim to intervene early. PMID:27005834

    The purpose of this study was to measure the concentrations of enrofloxacin and its metabolite ciprofloxacin following intravenous administration of enrofloxacin in the plasma and ear tissue of dogs with chronic end-stage otitis undergoing a total ear canal ablation and lateral bulla osteotomy. The goals were to determine the relationship between the dose of enrofloxacin and the concentrations of enrofloxacin and ciprofloxacin, and determine appropriate doses of enrofloxacin for treatment of chronic otitis externa and media. Thirty dogs were randomized to an enrofloxacin-treatment group (5, 10, 15 or 20 mg kg(-1)) or control group (no enrofloxacin). After surgical removal, ear tissue samples (skin, vertical ear canal, horizontal ear canal, middle ear) and a blood sample were collected. Concentrations of enrofloxacin and ciprofloxacin in the plasma and ear tissue were measured by high performance liquid chromatography. Repeated measures models were applied to log-transformed data to assess dosing trends and Pearson correlations were calculated to assess concentration associations. Ear tissue concentrations of enrofloxacin and ciprofloxacin were significantly (P ciprofloxacin concentrations, respectively. For bacteria with an minimal inhibitory concentration of 0.12-0.15 or less, 0.19-0.24, 0.31-0.39 and 0.51-0.64 microg mL(-1), enrofloxacin should be dosed at 5, 10, 15 and 20 mg kg(-1), respectively. Treatment with enrofloxacin would not be recommended for a bacterial organism intermediate or resistant in susceptibility to enrofloxacin since appropriate levels of enrofloxacin would not be attained.

    2011-03-01

    Full Text Available Abstract Background Scrub typhus, a mite-transmitted zoonosis caused by Orientia tsutsugamushi, is an endemic disease in Taiwan and may be potentially fatal if diagnosis is delayed. Case presentations We encountered a 23-year-old previously healthy Taiwanese male soldier presenting with the right ear pain after training in the jungle and an eleven-day history of intermittent high fever up to 39°C. Amoxicillin/clavulanate was prescribed for otitis media at a local clinic. Skin rash over whole body and abdominal cramping pain with watery diarrhea appeared on the sixth day of fever. He was referred due to progressive dyspnea and cough for 4 days prior to admission in our institution. On physical examination, there were cardiopulmonary distress, icteric sclera, an eschar in the right external auditory canal and bilateral basal rales. Laboratory evaluation revealed thrombocytopenia, elevation of liver function and acute renal failure. Chest x-ray revealed bilateral diffuse infiltration. Doxycycline was prescribed for scrub typhus with acute respiratory distress syndrome and multiple organ failure. Fever subsided dramatically the next day and he was discharged on day 7 with oral tetracycline for 7 days. Conclusion Scrub typhus should be considered in acutely febrile patients with multiple organ involvement, particularly if there is an eschar or a history of environmental exposure in endemic areas. Rapid and accurate diagnosis, timely administration of antibiotics and intensive supportive care are necessary to decrease mortality of serious complications of scrub typhus.

    1982-04-01

    Since Chandler's initial report in 1968 on malignant external otitis (MEO), this entity has been recognized in its earlier stages with increasing frequency. As a result of this, the availability of new antimicrobial agents, and the judicious use of surgery, there has been an improvement in the results of therapy. There remains, however, a subgroup of patients who continue to experience a significant mortality from this infection. A review and selected discussion of our experience with MEO from 1976 to 1979 is presented. Six patients have been diagnosed and successfully treated for MEO. They presented with problems ranging from severe otalgia to multiple cranial neuropathy. For the most part, therapy consisted of the now standard aminoglycoside and carbenicillin combination. Two of the patients were in the high mortality risk group. One of these patients developed an osteomyelitis which extended across the skull base resulting in bilateral cranial neuropathies. His therapy included surgery as well as long-term (months) outpatient treatment with tobramycin and carbenicillin with an excellent result. The second patient was treated similarly. The efficacy of this approach is discussed as well as the usefulness of radionuclide bone scanning in assessing the course and therapy of patients with MEO.

    Objective: To update the recent knowledge of the microbiological causes of canine otitis externa in Campania Region (Italy) and the antibiotic susceptibility patterns of the iso-lated strains. Methods: A total of 122 dogs were examined by otoscopy, and auricular swab samples were collected from both ears in 74 dogs presenting clinical bilateral otitis and from single ears in 48 dogs displaying clinical unilateral otitis. Cytological examination, bacteriological analysis and antimicrobial susceptibility tests were performed. Results: Thirty-one out of 122 dogs were positive for yeast species (25.4%, 95% con-fidence interval (CI): 18.2%–34.2%) with a higher prevalence of Malassezia pachy-dermatis (21/31 isolates, 67.7%, CI: 48.5%–82.7%), and a total of 91 out of 122 dogs were positive for bacterial species (74.6%;CI:65.8%–81.8%) with a higher prevalence of Staphylococcus pseudintermedius (45/143 isolates, 31.5%, CI: 24.1%–39.8%). These results are the first description of Streptococcus agalactiae-associated otitis. The yeasts isolated showed high levels of susceptibility to all antifungal agents tested; on the con-trary all the isolated bacterial strains were highly resistant to at least four out of ten antimicrobial classes. Both Gram-positive and Gram-negative bacteria showed high resistance to amoxicillin/clavulanate and kanamycin hence they are not recommended as initial empirical therapy for the otitis treatment. Conclusions: This update illustrates an increase in antibiotic resistances providing an insight into the current knowledge of the therapeutic procedures followed on canine otitis externa in Italy. It also emphasizes the importance of considering the results of the microbiological and sensitivity tests to decide on an appropriate antibiotic therapy.

    Some epidemiologic surveillance studies have recorded adverse drug reactions to radiocontrast agents. We aimed to investigate the incidence and management of acute adverse reactions (AARs) to Ultravist-370 and Isovue-370 in patients who underwent contrast-enhanced computed tomography (CT) scanning.Data from 137,473 patients were analyzed. They had undergone enhanced CT scanning with intravenous injection of Ultravist-370 or Isovue-370 during the period of January 1, 2006 to December 31, 2012 in our hospital. We investigated and classified AARs according to the American College of Radiology and the Chinese Society of Radiology (CSR) guidelines for iodinated contrast media. We analyzed risk factors for AARs and compared the AARs induced by Ultravist-370 and Isovue-370.Four hundred and twenty-eight (0.31%) patients experienced AARs, which included 330 (0.24%) patients with mild AARs, 82 (0.06%) patients with moderate AARs, and 16 (0.01%) patients with severe AARs (including 3 cases of cardiac arrest and one case of death). The incidence of AARs was higher with Ultravist-370 than with Isovue-370 (0.38% vs 0.24%, P < 0.001), but only for mild AARs (0.32% vs 0.16%, P < 0.001). Analyses on risk factors indicated that female patients (n = 221, 0.43%, P < 0.001), emergency patients (n = 11, 0.51%, P < 0.001), elderly patients aged 50 to 60 years (n = 135, 0.43%, P < 0.001), and patients who underwent coronary computed tomography angiography (CTA) (n = 55, 0.51%, P < 0.001) had a higher risk of AARs. Cutaneous manifestations (50.52%)-especially rash (59.74%)-were the most frequent mild AARs. Cardiovascular manifestations accounted for most moderate and severe AARs (62.91% and 48.28%, respectively). After proper management, the symptoms and signs of 96.5% of the AARs resolved within 24 hours without sequelae.Ultravist-370 and Isovue-370 are safe for patients undergoing enhanced CT scanning. The incidence of AARs is higher with Ultravist

  1. SPECT imaging in evaluating extent of malignant external otitis: case report

    Otitis externa, a benign inflammatory process of the external auditory canal, is general responsive to local therapy. Some patients however, develop a less controllable disease leading to chondritis and osteomyelitis of the base of the skull. The direct invasive characteristic of the disease has led to the descriptive term malignant external otitis (MEO), more appropriately called necrotizing or invasive external otitis. Malignant external otitis is caused by an aggressive pseudomonas or proteus infection that almost exclusively occurs in elderly diabetic patients. The primary imaging modalities previously used in the diagnosis and evaluation of MEO were standard planar scintigraphic techniques with technetium-99M (/sup 99m/Tc) bone agents and gallium-67 (67Ga), and pluridirectional tomography. The advent of high resolution computed tomography (CT) effectively allowed demonstration of the soft tissue extension and bone destruction associated with MEO, but still suffered from the low sensitivity constraints of all radiographic techniques in determining early inflammatory bone involvement. Recent work suggests that scintigraphic detection of MEO with /sup 99m/Tc-MDP and 67Ga, combined with the cross-sectional resolution of single photon emission computed tomography (SPECT) may be of value in planning treatment of this inflammatory condition

    Full Text Available Swab samples obtained from 96 dogs with chronic otitis externa were cultured for the isolation of Staphylococcus species. Of 57 staphylococcal strains, 41 (72% were coagulase-negative (CNS. The identification of staphylococci strains was made by standard procedures for the routine identification of staphylococci in clinical practice. S. sciuri was the most frequent species isolated (22.8% from chronic otitis externa in dogs followed by S. intermedius (12.3%, S. auricularis (10.5% and S. aureus (8.8%. Three (5.2% CNS strains could not be identified. Bacterial isolates were susceptible to enrofloxacin, gentamicin, cephalothin, chloramphenicol and neomycin. Resistance was most common to penicillin G, oxacillin and ampicillin.

  4. Gentamicin iontophoresis in the treatment of bacterial otitis externa in the guinea pig model.

    King, D M; Estrem, S A

    1990-10-01

    Pseudomonas otitis externa is one of the most common infections treated by otolaryngologists. Infections induced in 30 guinea pigs appeared similar to that seen in humans. The ears were then placed into four treatment groups: group A, which received a single cleaning; group B, which received a single cleaning followed by gentamicin drops 4 times daily; group C, which received a single cleaning followed by a single gentamicin iontophoresis treatment; and group D, the control group, which received no treatment. Infections were analyzed by grading edema, purulence, and erythema. An average of 10.2 days was required for control group to return to normal appearance. Groups A, B, and C had mean resolution times of 5.9, 4.7, and 4.3 days, respectively. Gentamicin iontophoresis appears to be promising, with results as good as drop therapy in otitis externa in the guinea pig model. PMID:2215045

  5. The evaluation of HRCT in the diagnosis of chronic otitis and mastoiditis

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

    2000-01-01

    Malignant External Otitis (MEO) usually occurring in middle aged or elderly diabetics is uncommonly seen in children and rarely in infants. Various studies done so far have proved that immunological disturbance is present in case of MEO, Eliashiv et al (1978) and Yust et al (1980) have proved that cell mediated immunity is depressed in cases of MEO occurring in diabetics. MEO occurring in a four month old grosslly immunadeficient infant is indeed a very rare presentation. Occurrence of MEO in...

Finally, one can think of educational media, i.e. media used for educational purposes.After having specified these three subject areas, t...

  10. Early detection and intervention using neutrophil gelatinase-associated lipocalin (NGAL may improve renal outcome of acute contrast media induced nephropathy: A randomized controlled trial in patients undergoing intra-arterial angiography (ANTI-CIN Study

    Stiegler Philipp

    2011-08-01

    Full Text Available Abstract Background Patients with pre-existing impaired renal function are prone to develop acute contrast media induced nephropathy (CIN. Neutrophil gelatinase-associated lipocalin (NGAL, a new biomarker predictive for acute kidney injury (AKI, has been shown to be useful for earlier diagnosis of CIN; however, urinary NGAL values may be markedly increased in chronic renal failure at baseline. Results from those studies suggested that urinary NGAL values may not be helpful for the clinician. An intravenous volume load is a widely accepted prophylactic measure and possibly a reasonable intervention to prevent deterioration of renal function. The aim of our study is to evaluate NGAL as an early predictor of CIN and to investigate the clinical benefit of early post-procedural i.v. hydration. Methods/Design The study will follow a prospective, open-label, randomized controlled design. Patients requiring intra-arterial contrast media (CM application will be included and receive standardized, weight-based, intravenous hydration before investigation. Subjects with markedly increased urinary NGAL values after CM application will be randomized into one of two study groups. Group A will receive 3-4 ml/kg BW/h 0.9% saline intravenously for 6 hours. Group B will undergo only standard treatment consisting of unrestricted oral fluid intake. The primary outcome measure will be CIN defined by an increase greater than 25% of baseline serum creatinine. Secondary outcomes will include urinary NGAL values, cystatin C values, contrast media associated changes in cardiac parameters such as NT-pro-BNP/troponin T, changes in urinary cytology, need for renal replacement treatment, length of stay in hospital and death. We assume that 20% of the included patients will show a definite rise in urinary NGAL. Prospective statistical power calculations indicate that the study will have 80% statistical power to detect a clinically significant decrease of CIN of 40% in the

    1982-09-01

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

  14. Media education.

    Strasburger, Victor C

    2010-11-01

    The American Academy of Pediatrics recognizes that exposure to mass media (eg, television, movies, video and computer games, the Internet, music lyrics and videos, newspapers, magazines, books, advertising) presents health risks for children and adolescents but can provide benefits as well. Media education has the potential to reduce the harmful effects of media and accentuate the positive effects. By understanding and supporting media education, pediatricians can play an important role in reducing harmful effects of media on children and adolescents. PMID:20876180

  15. Social Media and Mobile Apps for Health Promotion in Australian Indigenous Populations: Scoping Review

    Brusse, Carl; McAullay, Daniel; Dowden, Michelle

    2014-01-01

    Background Health promotion organizations are increasingly embracing social media technologies to engage end users in a more interactive way and to widely disseminate their messages with the aim of improving health outcomes. However, such technologies are still in their early stages of development and, thus, evidence of their efficacy is limited. Objective The study aimed to provide a current overview of the evidence surrounding consumer-use social media and mobile software apps for health promotion interventions, with a particular focus on the Australian context and on health promotion targeted toward an Indigenous audience. Specifically, our research questions were: (1) What is the peer-reviewed evidence of benefit for social media and mobile technologies used in health promotion, intervention, self-management, and health service delivery, with regard to smoking cessation, sexual health, and otitis media? and (2) What social media and mobile software have been used in Indigenous-focused health promotion interventions in Australia with respect to smoking cessation, sexual health, or otitis media, and what is the evidence of their effectiveness and benefit? Methods We conducted a scoping study of peer-reviewed evidence for the effectiveness of social media and mobile technologies in health promotion (globally) with respect to smoking cessation, sexual health, and otitis media. A scoping review was also conducted for Australian uses of social media to reach Indigenous Australians and mobile apps produced by Australian health bodies, again with respect to these three areas. Results The review identified 17 intervention studies and seven systematic reviews that met inclusion criteria, which showed limited evidence of benefit from these interventions. We also found five Australian projects with significant social media health components targeting the Indigenous Australian population for health promotion purposes, and four mobile software apps that met inclusion

  16. Temporal Bone Osteomyelitis: The Relationship with Malignant Otitis Externa, the Diagnostic Dilemma, and Changing Trends

    Jia-Cheng Chen

    2014-01-01

    Full Text Available Fifty-five patients hospitalized for osteomyelitis of the temporal bone between 1990 and 2011 were divided into two study groups: group 1 was patients collected from 1990 to 2001 and group 2 was composed of patients between 2002 and 2011. Clinical diagnostic criteria and epidemiologic data were analyzed to illustrate the altering features of osteomyelitis of the temporal bone. Group 1 patients were characterized by high prevalence of diabetes and more commonly suffered from otalgia, otitis externa and granulation tissue in the external auditory canal and higher positive culture for Pseudomonas aeruginosa. Noticeable changing trends were found between both groups, including declining prevalence of diabetes, fewer patients complaining of pain or presenting with otitis externa, and canal granulation, and increased variety of pathogens in group 2. We should highlight the index of clinical suspicion for osteomyelitis of the temporal bone, even in nondiabetic or immunocompetent patients. Painless otorrhea patients were also at risk of osteomyelitis of the temporal bone, especially patients with previous otologic operation. Increased multiplicity of pathogens amplified the difficulty of diagnosis for osteomyelitis of the temporal bone.

  17. Assessment of the Antimicrobial Activity of Algae Extracts on Bacteria Responsible of External Otitis

    Gianluca Pane

    2015-10-01

    Full Text Available External otitis is a diffuse inflammation around the external auditory canal and auricle, which is often occurred by microbial infection. This disease is generally treated using antibiotics, but the frequent occurrence of antibiotic resistance requires the development of new antibiotic agents. In this context, unexplored bioactive natural candidates could be a chance for the production of targeted drugs provided with antimicrobial activity. In this paper, microbial pathogens were isolated from patients with external otitis using ear swabs for over one year, and the antimicrobial activity of the two methanol extracts from selected marine (Dunaliella salina and freshwater (Pseudokirchneriella subcapitata microalgae was tested on the isolated pathogens. Totally, 114 bacterial and 11 fungal strains were isolated, of which Staphylococcus spp. (28.8% and Pseudomonas aeruginosa (P. aeruginosa (24.8% were the major pathogens. Only three Staphylococcus aureus (S. aureus strains and 11 coagulase-negative Staphylococci showed resistance to methicillin. The two algal extracts showed interesting antimicrobial properties, which mostly inhibited the growth of isolated S. aureus, P. aeruginosa, Escherichia coli, and Klebsiella spp. with MICs range of 1.4 × 109 to 2.2 × 1010 cells/mL. These results suggest that the two algae have potential as resources for the development of antimicrobial agents.

  18. Antimicrobial susceptibility of Pseudomonas aeruginosa isolates from dogs with otitis externa.

    Mekić, S; Matanović, K; Šeol, B

    2011-07-30

    Pseudomonas aeruginosa is a common cause of otitis externa in dogs, and treatment of these infections is becoming problematic because of the increasing number of multiresistant strains. The aim of the present study was to compare the in vitro activities of cefepime, ceftazidime, enrofloxacin, ciprofloxacin, gentamicin and ticarcillin/clavulanic acid against 104 strains of P aeruginosa isolated from dogs with otitis externa. Antimicrobial susceptibility and minimum inhibitory concentrations, in µg/ml, were evaluated by the E test (bioMérieux). The most active compound was ceftazidime, with 100 per cent efficiency. The majority of tested strains were susceptible to ticarcillin/clavulanic acid (89.4 per cent), followed by ciprofloxacin (88.5 per cent) and cefepime (60.6 per cent). The highest resistance was observed to enrofloxacin (51.9 per cent) and gentamicin (43.3 per cent). Large numbers of strains were intermediately susceptible to antibiotics registered for use in veterinary medicine in Croatia--enrofloxacin (47.1 per cent) and gentamicin (41.3 per cent).

    Media are part of our lives today. Our pupils watch TV, play online games, blog, upload videos on YouTube, use Facebook, etc. Messages transmitted by the media flow constantly into our and their minds. Media literacy provides us with a range of information and abilities which help us analyse, evaluate, and even create messages in various modes of the media. Students are encouraged to think critically about the media they consume. Hobbs has found out that media literacy implies: a set of skill...

    Freedman, D.; Schlosberg, Justin

    2011-01-01

    Research shows that near-universal digital media access in the United Kingdom has yielded broad benefits for citizenship and democracy. But key areas of concern have emerged that continue to pose threats to independence and diversity. These include sustained financial crises within regional and local media, public service broadcasting, and the press sector at large; acute sites of cross-media concentration; and persistent digital divides in terms of access to “quality” output. This report...

  4. Malignant external otitis: the role of computed tomography and radionuclides in evaluation

    Nine patients with malignant external otitis (MEO) were evaluated with Tc-99m bone scans, Ga-67 citrate scans, pluridirectional tomography, and computed tomographic (CT) scans in order to assess the role of each in the diagnosis and management of MEO. The Tc-99m and Ga-67 citrate scans were the most accurate studies in the initial identification of disease activity, while the return to normal or improvement of the Ga-67 citrate scan has been shown to correlate best with clinical resolution of MEO. CT demonstrated soft-tissue disease and central skull base osteomyelitis better than pluridirectional tomography. CT is excellent for localizing and following the progression of bone disease; however, because reossification of the skull base is a very slow process, CT cannot be used to follow accurately regression or inactivity of MEO affecting this area. CT is the best modality for following soft-tissue extension of MEO

    Full Text Available BACKGROUND: Acute bacterial meningitis (ABM remains a significant worldwide cause of death in adults. Even in the antibiotic era, the mortality rate in ABM remains significant and has been reported in the range of 8-40%. AIM: The aim of this study was to assess the characteristics of epidemiology, clinical manifestations, treatment modalities and outcome of patients with ABM in Southeast Turkey. SETTINGS AND DESIGN: This retrospective study included all cases of community-acquired ABM diagnosed and treated in Dicle University Hospital between June 1996 and December 2002. METHODS AND PATIENTS: The study group consisted of 186 adult patients (110 male, 76 female with ABM, those patients who are older than 14 years, followed up at Dicle University Hospital from June 1996 to December 2002. Patients′ charts were retrospectively reviewed, clinical characteristics were recorded and final data were analyzed. STATISTICAL ANALYSIS: In statistical analyses, the Chi-square test was used for binary variables and Student′s t-test for continuous variables. RESULTS: The patients′ mean age was 30.2 ± 15.3 years (range 14 to 90 years. On admission, typical symptoms of meningitis were found in most of the patients: headache in 92.5%, fever in 88.2%, and nuchal rigidity in 80.1%. The main predisposing factor for ABM was otitis media (40 patients, 21.5% and closed head trauma (12 patients, 6.5%. Streptococcus pneumonia was the most common identified pathogen. Twenty-nine patients (15.6% died during hospitalization period. In multivariate analyses, the significant mortality factor was found as initial level of consciousness, low cerebrospinal fluid/blood glucose ratio, high erythrocyte sedimentation rate and initial treatment by penicillin G. CONCLUSIONS: Although still remains as a serious infection, early diagnosis and effective treatment may reduce fatal outcome and improve the course of the disease in patients with ABM. Ceftriaxone should be considered as

    Across Europe and beyond, the promotion of media literacy, for children and adults, has acquired an important public urgency. Traditional literacy is seen to be no longer sufficient for participation in today’s society. Citizens need to be media literate, it is claimed, to enable them to cope more effectively with the flood of information in today’s highly mediated societies. As teachers, politicians and policy makers everywhere struggle with this rapid shift in media culture, greater respons...

    Full Text Available Foreign bodies in External Auditory Canal (EAC are common in both adults and children. Removal of foreign body requires skill but usually successfully performed in the ENT department. A 40 year old female patient presented with right ear discharge with decreased hearing. On examination, a pale, scanty, mucopurulent discharge, foul smelling with blood tinge, persisting even after medications. After aural toileting, tympanic membrane was perforated with granulation tissue in middle ear. Multiple broom sticks were found in the external auditory canal, mastoid antrum was removed via post auricular approach with excision of polyp with radical mastoid exploration. Removal of foreign body from EAC is an essential skill for ENT surgeon. Careful removal can prevent further trauma and complications. An aural polyp with ear discharge, never attempt to pull/avulsion. [Int J Res Med Sci 2015; 3(4.000: 1030-1031

    Streptococcus pneumoniae infections result in a range of human diseases and are responsible for almost one million deaths annually. Pneumococcal disease is mediated in part through surface structures and an anti-phagocytic capsule. Recent studies have shown that nonencapsulated S. pneumoniae (NESp) make up a significant portion of the pneumococcal population and are able to cause disease. NESp lack some common surface proteins expressed by encapsulated pneumococci, but express surface protein...
