ABSTRACT

Patients with patulous Eustachian tubes(PET) usually suffer from annoying symptoms, such as tinnitus, autophony and aural fullness, due to the excessive opening of the Eustachian tube. There is no uniform standard of treatment, and conservative therapy combined with"Stepup"surgical intervention strategy is the main treatment. In this article, we reviewed various surgical treatments of patulous Eustachian tube in recent years, including key points of surgical operation, effectiveness, safety and complications. Full communication and evaluation are needed to establish appropriate patients' expectations preoperatively. A "Stepup" treatment strategy will be carried out, including conservative treatment, tympanic membrane surgery, Eustachian tube pharyngeal orifice constriction surgery, Eustachian tube tympanic orifice plug surgery and Eustachian tube muscle surgery, which aims to maintain normal Eustachian tube function and good middle ear ventilation.

ABSTRACT

INTRODUCCIÓN. La patología de oído es una enfermedad frecuente en nuestro medio, asociada a infecciones a repetición del oído, con la presencia de perforación timpánica y colesteatoma, que determinará la presencia de lesiones mucho más acentuadas en cuanto a la evolución auditiva o complicaciones locales o sistémicas. OBJETIVO. Determinar la asociación existente entre la presencia de colesteatoma y perforación timpánica en pacientes con otitis media crónica. MATERIALES Y MÉTODOS. Estudio epidemiológico analítico retrospectivo. Población de 4 733 y muestra de 75 pacientes para casos y 75 para controles basados en historias clínicas tomadas del sistema informático AS 400, que acudieron a la consulta externa de torrinolaringología del Hospital de Especialidades Carlos Andrade Marín en el periodo de enero de 2018 a diciembre de 2019; Criterios de inclusión para grupo de casos: Hombres y mujeres de 20 a 65 años de edad, diagnóstico de otitis media crónica, diagnóstico de colesteatoma ótico. Criterios de inclusión para grupo controles: Hombres y mujeres de 20 a 65 años de edad, no presentar diagnóstico de colesteatoma. RESULTADOS. Se observó una relación fuerte entre el poseer perforación timpánica y el desarrollo de colesteatoma con un valor de OR 33,14 con un IC al 95% de 31,94 ­ 34,34, con lo que se comprobó la hipótesis del estudio. Se determinó que la perforación timpánica es un factor de riesgo asociado con el desarrollo de colesteatoma en pacientes con otitis media crónica, la prevalencia de colesteatoma en relación a la edad estuvo en un 72% en pacientes de 41 a 65 años, con mayor predominancia en mujeres en un 57,3%. DISCUSIÓN. La presencia de perforación timpánica de acuerdo a lo observado es un factor de riesgo para el desarrollo de colesteatoma, ligado en su mayoría a cuadros de Otitis Media Crónica. CONCLUSIONES. Se confirmó que la perforación timpánica, es un factor de riesgo en el desarrollo del colesteatoma en los pacientes que tienen otitis media crónica, lo que demuestra la necesidad de manejo actualizado y continuo en pacientes con esta patología de oído. Se requieren estudios con muestras más amplias para determinar otros factores de riesgo como sexo, nivel de educación y edad que podrían influir en el desarrollo de colesteatoma.


INTRODUCTION. Ear pathology is a frequent disease in our environment, associated with repeated ear infections, with the presence of tympanic perforation and cholesteatoma, which will determine the presence of much more accentuated lesions in terms of auditory evolution or local or systemic complications. OBJECTIVE. To determine the association between the presence of cholesteatoma and tympanic perforation in patients with chronic otitis media. MATERIALS AND METHODS. Retrospective analytical epidemiological study. Population of 4 733 and sample of 75 patients for cases and 75 for controls based on clinical histories taken from the AS 400 computer system, who attended the Otorhinolaryngology outpatient clinic of the Carlos Andrade Marín Specialties Hospital in the period from January 2018 to December 2019; Inclusion criteria for case group: Men and women aged 20 to 65 years, diagnosis of chronic otitis media, diagnosis of otic cholesteatoma. Inclusion criteria for controls group: men and women aged 20 to 65 years, no diagnosis of cholesteatoma. RESULTS. A strong relationship was observed between having tympanic perforation and the development of cholesteatoma with an OR value of 33,14 with a 95% CI of 31,94 - 34,34, thus proving the study hypothesis. It was determined that tympanic perforation is a risk factor associated with the development of cholesteatoma in patients with chronic otitis media, the prevalence of cholesteatoma in relation to age was 72% in patients aged 41 to 65 years, with greater predominance in women in 57,3%. DISCUSSION. The presence of tympanic perforation according to what was observed is a risk factor for the development of cholesteatoma, mostly linked to Chronic Otitis Media. CONCLUSIONS. It was confirmed that tympanic perforation is a risk factor in the development of cholesteatoma in patients with chronic otitis media, which demonstrates the need for updated and continuous management in patients with this ear pathology. Studies with larger samples are required to determine other risk factors such as sex, education level and age that could influence the development of cholesteatoma.

ABSTRACT

Resumen La otitis media constituye una de las consultas médicas más comunes en la población infantil. Se caracteriza por la inflamación del oído medio en presencia de exudado en la cavidad timpánica, abarcando un amplio espectro de formas clínicas, dentro de las que destacan la otitis media aguda, con efusión y crónica. La hipoacusia de conducción es una de las complicaciones de la otitis media, por lo que es lógico pensar que algunas habilidades del lenguaje y cognición infantil podrían verse afectadas secundariamente. Sin embargo, la evidencia en torno al tema no es concluyente y se aprecian opiniones contrapuestas; asimismo, no existe actualmente una revisión de la literatura que agrupe las investigaciones existentes en torno al tema. Por ello, el presente estudio pretende identificar y analizar la evidencia científica disponible sobre el efecto de la otitis media en el desarrollo de la cognición y lenguaje infantil. Se realizó una revisión de la literatura guiada por protocolo PRISMA en bases de datos de acuerdo a términos claves. Fueron analizados 8 artículos que cumplieron con los criterios de inclusión. Los resultados recabados sugieren, por una parte, que la otitis media afecta el lenguaje en sus distintas dimensiones, el vocabulario comprensivo y la longitud media del enunciado; mientras que, por otra parte, no se encontró efecto directo de la otitis media o hipoacusia sobre la comprensión del lenguaje. Se concluye que las investigaciones analizadas presentan gran variabilidad de resultados y conclusiones. No existen reportes sobre su impacto en otros dominios de la cognición.


Abstract Otitis media is one of the most common medical consultations in children. It is characterized by inflammation of the middle ear in the presence of exudate in the tympanic cavity, covering a wide spectrum of clinical forms, among which acute otitis media, otitis media with effusion and chronic otitis media are the most outstanding. Conductive hearing loss is one of the complications of otitis media, so it is logical to think that some language and cognitive skills in children could be affected. However, the evidence on this matter is not conclusive and there are conflicting opinions; likewise, there is currently no review of the literature that compile the existing research on this topic. Therefore, the present study aims to identify and analyze the available scientific evidence on the effect of otitis media on the development of children's cognition and language. A review of the literature, guided by PRISMA protocol, was conducted in databases according to key terms. Eight articles that met the inclusion criteria were analyzed. The results suggest, on the one hand, that otitis media affects language in its different dimensions, comprehensive vocabulary and average sentence length; while on the other hand, no direct effect of otitis media or hearing loss on language comprehension was found. In is concluded that the research that were analyzed present great variability of results and conclusions. There are no reports on its impact on other domains of cognition.

ABSTRACT

Objective@#To compare the effect of topical epidermal growth factor (EGF) instillation versus observation alone on healing of acute tympanic membrane perforations in terms of closure and hearing test results. @*Methods@#Design: Randomized, Open label, Clinical Trial. Setting: Tertiary Government Training Hospital. Participants: Seventeen (17) ENT-HNS OPD patients aged between 18 to 65 years old diagnosed with acute tympanic membrane perforation were included in the study. Group A underwent observation while group B was treated with recombinant human EGF solution. Follow- up was on a weekly basis (7th, 14th, 21st and 28th days) where video otoscopy for documentation and measurement of perforation using ImageJTM software was done. Pure tone audiometry was used to compare hearing improvement pre and post study in both observation and treatment groups.@*Results@#At baseline, there was no significant difference in the sizes of perforations: 24.20 ± 9.95 (treatment) vs. 32.64 ± 11.62 (observation) with a p-value of .131. Following treatment, mean changes in perforation size were significantly greater in the treatment group compared to the observation group from baseline to day 7 (M = -9.08, n = 15.11 vs. M = -1.06, n = 31.58); p = .009; day 7 to 14 (M = -6.37, n = 13.78 vs. M = -0.79, n = 30.79); p = .003; and from day 14 to 21 (M = -5.65, n = 10.89 vs. M = -0.72, n = 30.07); p = .004 but not from day 21 to 28 (M = -4.16, n = 13.99 vs. M = -0.36, n = 29.71; p = .021. From baseline pure tone averages, four participants with mild hearing loss and two with moderate hearing loss achieved normal hearing in the treatment group (while one each with moderate and severe hearing loss did not improve). None of the observation group participants had improved hearing. @*Conclusion@#Based on our limited experience, topical EGF can be used for traumatic tympanic membrane perforation and otitis media with dry ear perforation during the acute phase or within 3 months of perforation.

ABSTRACT

Objective: To analyze the incidence and risk factors of otologic disorders in patients with Turner syndrome (TS), so as to provide management strategies for ear health. Methods: This study is a prospective study based on questionnaires and a cross-sectional study. The TS patients who visited our hospital from 2010 January to 2021 March were included (A total of 71 patients with TS were included in this study. the age of TS diagnosed was 3- to 11-year-old, age of visiting ENT department was 4- to 27-year-old) and the incidence of otologic diseases in different age groups was investigated by questionnaires. The cross-sectional study included ear morphology and auditory function assessment, and further analysis of the risk factors that related to ear disease. Prism was used for data analysis. Results: The investigation found that the incidence of acute otitis media in patients aged 3-6 and 7-12 years was higher than that of patients over 12 years old, which was 33.8%(24/71), 42.9%(30/70)and 23.5%(8/34), respectively; 21.1% (15/71) of patients were recurrent acute otitis media in patients aged 3-6 years, and about 46.6% (7/15)of them persisted beyond 6-year. The prevalence of otitis media with effusion in the three groups was 32.4%(23/71), 34.3%(24/70)and 38.2%(13/34), respectively; the recurrence rate of tympanocentesis was 100%(7/7), 42.9%(3/7)and 50.0%(1/2), which was significantly higher than that of grommet insertion. For age groups of 3-6 and 7-12 years, the prevalence of acute otitis media and secretory otitis media was lower in the X chromosome structure abnormal patients; while for patients older than 12 years, otitis media with effusion was the highest prevalence in Y-chromosome-containing karyotypes. In addition, the prevalence of acute otitis media and otitis media with effusion in patients with other system diseases were increased significantly. A cross-sectional study found that 7.0% (5/71)of the lower auricular, 4.2% (3/71)of the external auditory canal narrow, and 38.0% (27/71)of the tympanic membrane abnormality. 35.2%(25/71) had abnormal hearing, including 17 cases of conductive deafness, 6 cases of sensorineural hearing loss, and 2 cases of mixed deafness. The rest of the patients had normal hearing, but 6 of them had abnormalities in otoacoustic emission. Eustachian tube function assessment found that the eustachian tube dysfunction accounted for 38%(27/71). Hearing loss and abnormal Eustachian tube function were not significantly related to karyotype(Chi-square 2.83 and 2.84,P value 0.418 and 0.417), but significantly related to other system diseases(Chi-square 13.43 and 7.53,P value<0.001). Conclusions: The incidence of TS-related otitis media and auditory dysfunction is significantly higher than that of the general population. It not only occurs in preschool girls, but also persists or develops after school age. Accompanied by other system diseases are risk factors for ear diseases. Clinicians should raise their awareness of TS-related ear diseases and incorporate ear health monitoring into routine diagnosis and treatment.

ABSTRACT

This study investigated the antibacterial potential of Euphorbia hirtawhole plant extracts, honey and conventional antibiotics and their synergistic effects against selected multidrug resistant and typed bacterial strains associated with otitis media. E. hirtawhole plant extract was purified using column chromatography technique. The antibacterial assays of extracts were done using standard microbiological procedures. Protein, sodium and potassium ion leakage of the synergistic mixtures was determined using flame-photometry. At 100 mg/ml, acetone extracts presented highest inhibition against S. aureus (NCTC 6571) with 32 ± 0.83 mm zone of inhibition. The fractional inhibitory concentration indices displayed higher synergism in combination of plant extract, honey and ciprofloxacin against P. mirabilisat 0.02 compared to drug combination synergy standard (≤ 0.5). This work revealed augmentation of ciprofloxacin potency when combined with purified E. hirta acetone extract and honey and implies their high potential in the treatment of multidrug resistant infectionof otitis media.


Este estudio investigó el potencial antibacteriano de extractos de plantas enteras de Euphorbia hirta, miel y antibióticos convencionales y sus efectos sinérgicos contra cepas bacterianas seleccionadas multirresistentes y tipificadas asociadas con la otitis media. El extracto de la planta entera de E. hirtase purificó usando la técnica de cromatografía en columna. Los ensayos antibacterianos de extractos se realizaron utilizando procedimientos microbiológicos estándar. La fuga de iones de proteínas, sodio y potasio de las mezclas sinérgicas se determinó mediante fotometría de llama. A 100 mg/ml, los extractos de acetona presentaron la mayor inhibición contra S. aureus (NCTC 6571) con una zona de inhibición de 32 ± 0,83 mm. Los índices de concentración inhibitoria fraccional mostraron un mayor sinergismo en combinación de extracto de planta, miel y ciprofloxacina contra P. mirabilisa 0,02 en comparación con el estándar de sinergia de combinación de fármacos (≤ 0,5). Este trabajo reveló un aumento de la potencia de la ciprofloxacina cuando se combina con extracto de acetona purificado de E. hirtay miel e implica sualto potencial en el tratamiento de infecciones de otitis media resistentes a múltiples fármacos.

ABSTRACT

Abstract Introduction: As a supplement, beta-glucan has various therapeutic healing effects generated by the immune cells. It has been scientifically approved and proven to be a biological defense modifier. The aim of this study was to investigate the effects of beta-glucan on treatments administered in an acute otitis media model Objectives: This study investigated the effect of beta-glucan on the treatment of acute otitis media in an acute otitis media -induced animal model. Efficacy was evaluated both immunologically and histologically. Methods: The study sample comprised 35 adult rats, randomly separated into 5 groups of 7: Group 1 (control), Group 2 (acute otitis media, no treatment), Group 3 (acute otitis media + antibiotic), Group 4 (acute otitis media + beta-glucan) and Group 5 (acute otitis media + beta-glucan + antibiotic). Analyses were made of the histopathology and immunology examination results in respect of thickening of the tympanic membrane, epithelium damage, inflammation, and sclerosis. In all groups the serum levels of TNF-α, IL-4, IL-6 and IL-1β were evaluated. Results: All serum cytokine levels were significantly lower in the beta-glucan and antibiotictreated groups compared to the acute otitis media Group. Significant differences in tympanic membrane thickness, inflammation, epithelium damage, and sclerosis values were observed between the acute otitis media + antibiotic and acute otitis media + beta-glucan Groups. According to these parameters, the values in aute otitis media + antibiotic + beta-glucan Group were markedly lower than those of the other groups. There was a significant difference in the acute otitis media + antibiotic + beta-glucan Groups compared to acute otitis media Group (p < 0.001). Conclusions: Both antibiotic and beta-glucan treatment reduced acute otitis media signs of inflammations in an acute otitis media-induced rat model, decreasing histological damage and cytokine levels. Co-administration of antibiotic and beta-glucan led to a significant reduction in tympanic membrane thickness, inflammation, and epithelium damage. Antibiotic + beta-glucan treatment resulted in a greater decrease in tympanic membrane thickness, inflammation, and epithelium damage than in the other groups. From these results, it can be suggested that beta-glucan, in combination with antibiotics may provide an alternative for the treatment of acute otitis media.


Resumo Introdução: Como suplemento, o beta-glucano apresenta vários efeitos terapêuticos gerados pelas células imunológicas. Cientificamente aprovado, mostrou ser um modificador de defesa biológica. Objetivo: Investigar os efeitos do beta-glucano nos tratamentos administrados em um modelo de otite média aguda induzida em um modeloanimal. A eficácia foi avaliada imunológica e histologicamente. Método: A amostra do estudo foi composta por 35 ratos adultos, divididos aleatoriamente em 5 grupos de 7: grupo 1 (controle), grupo 2 (otite média aguda, sem tratamento), grupo 3 (otite média aguda + antibiótico), grupo 4 (otite média aguda + beta-glucano) e grupo 5 (otite média aguda + beta-glucano + antibiótico). Foram feitas análises dos resultados dos exames histopatológicos e imunológicos em relação ao espessamento da membrana timpânica, dano ao epitélio, inflamação e esclerose. Os níveis séricos de TNF-α, IL-4, IL-6 e IL-β foram avaliados em todos os grupos. Resultados: Todos os níveis séricos de citocinas foram significativamente mais baixos nos grupos tratados com beta-glucano e antibióticos em comparação com o grupo otite média aguda. Diferenças significativas na espessura da membrana timpânica, inflamação, dano do epitélio e esclerose foram observadas entre os grupos otite média aguda + antibiótico e otite média aguda + beta-glucano. De acordo com esses parâmetros, os valores no grupo otite média aguda + antibiótico + beta-glucano foram acentuadamente inferiores aos dos demais grupos. Houve uma diferença significante no grupo otite média aguda + antibiótico + beta-glucano em comparação ao grupo otite média aguda (p < 0,001). Conclusão: Ambos os tratamentos com antibiótico e com beta-glucano reduziram os sinais de inflamação da otite média aguda em um modelo de rato com otite média aguda induzida, diminuíram os danos histológicos e os níveis de citocinas. A administração concomitante de antibiótico e beta-glucano levou a uma redução significativa na espessura da membrana timpânica, inflamação e danos ao epitélio. O tratamento com antibióticos + beta-glucano resultou em maior diminuição na espessura da membrana timpânica, inflamação e danos no epitélio do que nos outros grupos. A partir desses resultados, pode-se sugerir que o beta-glucano, em combinação com antibióticos, pode fornecer uma opção para o tratamento da otite média aguda.

ABSTRACT

Introducción: La COVID-19 es una enfermedad que ha mostrado una baja morbilidad y mortalidad en pediatría. Las crisis febriles constituyen una de las causas más frecuentes de admisión en los servicios de urgencia y de interconsultas con el neuropediatra. Objetivo: Interpretar la presencia de crisis febril simple en pacientes admitidos en servicios de urgencia pediátricos como manifestación inicial de COVID-19. Presentación del caso: Paciente femenina de un año de edad, con antecedentes de salud anterior que acude al cuerpo de guardia con fiebre de 38 ℃; y crisis motora, de inicio generalizada, tónico-clónica, que cedió con medidas antitérmicas. Por protocolo se realiza punción lumbar la cual resulta negativa. Se ingresa, 24 horas después comienza con manifestaciones catarrales, se hace otoscopia y se diagnostica una otitis media aguda, por lo que se inicia tratamiento antibiótico. Se realiza la prueba de reacción en cadena de la polimerasa para la COVID-19 con resultado positivo, por lo que se remite para el Hospital Pediátrico San Miguel del Padrón. Conclusiones: Se debe sospechar la presencia de COVID-19 ante paciente que acude a servicio de urgencias por una crisis febril, como único problema de salud. LA COVID-19 es una enfermedad que ha demostrado que se puede presentar de diversas formas(AU)


Introduction: COVID-19 is a disease that has shown low morbidity and mortality in pediatrics. Febrile crises are one of the most common causes of admission to emergency services and consultations with the neuropediatrician. Objective: Interpret the presence of simple febrile crisis in patients admitted to pediatric emergency services as an initial manifestation of COVID-19. Case presentation: One-year-old female patient, with a previous health history, who is attended in the emergency service with a fever of 38 ℃; and motor crisis, of widespread onset, with tonic-clonic seizures, which yielded with antypiretic measures. By protocol, lumbar puncture is performed which is negative. She was admitted, and 24 hours later there is an onset of catarrhal manifestations; an otoscopy is performed and acute otitis media is diagnosed, so antibiotic treatment is initiated. The polymerase chain reaction test for COVID-19 (PCR) is performed with a positive result, so, the patient is referred to the San Miguel del Padrón Pediatric Hospital. Conclusions: COVID-19 should be suspected in patients who attend to the emergency services due to a febrile crisis as the only health problem. COVID-19 is a disease that has been shown to occur in a variety of ways(AU)

A rinossinusite crônica (RSC) é uma síndrome caracterizada pela inflamação da mucosa nasal e dos seios paranasais por pelo menos 12 semanas, acometendo de 5% a 12% da população geral. A síndrome é associada a alta morbidade e considerada um grande problema de saúde pública devido a sua prevalência, seu custo para a sociedade e ao impacto que acarreta na qualidade de vida dos pacientes e em seu desempenho escolar ou profissional. Ademais, a RSC está associada a diversas comorbidades, como dermatite atópica, distúrbios respiratórios do sono, conjuntivite, otite média, asma e problemas emocionais. O dupilumabe é eficaz e seguro no tratamento da RSC com polipose nasal. A eficácia é progressiva no primeiro ano de tratamento, e a posologia de 300 mg a cada duas semanas é superior em relação à de cada quatro semanas. A interrupção do tratamento com 24 semanas acarreta a perda parcial de seus efeitos benéficos. O imunobiológico também é eficaz no controle da asma nos pacientes que apresentam essa doença como comorbidade. Alguns pacientes podem apesentar aumento transitório de eosinófilos sanguíneos, e 2,7% desenvolveram conjuntivite como reação adversa nos estudos SINUS-24 e SINUS-52. O dupilumabe é uma excelente opção terapêutica no tratamento concomitante de múltiplas doenças caracterizadas pela inflamação de tipo II.


Chronic rhinosinusitis (CRS) is a syndrome characterized by inflammation of the nasal mucosa and paranasal sinuses for at least 12 weeks, affecting 5% to 12% of the general population. The syndrome is associated with high morbidity and is considered a major public health problem because of its prevalence, its cost to society, and the impact it has on patients' quality of life and on their school or professional performance. Furthermore, CRS is associated with several comorbidities, such as atopic dermatitis, sleep-disordered breathing, conjunctivitis, otitis media, asthma, and emotional problems. Dupilumab is effective and safe in the treatment of CRS with nasal polyposis. Effectiveness is progressive in the first year of treatment, and a dosage of 300 mg every two weeks is more effective than that of every four weeks. Discontinuing treatment at 24 weeks results in partial loss of its beneficial effects. The biological drug is also effective in controlling asthma in patients who have this disease as a comorbidity. Some patients may experience a transient increase in blood eosinophils, and 2.7% developed conjunctivitis as an adverse reaction in the SINUS-24 and SINUS-52 studies. Dupilumab is an excellent therapeutic option in the concomitant treatment of multiple diseases characterized by type II inflammation.

ABSTRACT

Resumen. La otitis media es una infección frecuente en la infancia, la cual puede producir complicaciones, incluidas las neurológicas graves, en cuatro de cada 100 niños en países en desarrollo. Se presenta el caso de una niña de nueve años sin antecedentes de enfermedad que consultó por otitis media derecha, otorrea, síndrome de hipertensión intracraneal y parálisis del VI nervio craneal contralateral a la lesión. La tomografía computarizada de cráneo y la resonancia magnética cerebral revelaron otomastoiditis crónica, apicitis petrosa, y trombosis de los senos transverso y sigmoide, el bulbo yugular y la vena yugular interna derecha. Recibió tratamiento antibiótico y quirúrgico. Este caso refleja el espectro de complicaciones intracraneales y extracraneales asociadas con la otitis media aguda en la era antibiótica. El examen físico permite la detección precoz de la hipertensión intracraneal, con signos como el papiledema y la parálisis del VI par contralateral como hallazgo inusual.


Abstract. Otitis media is a frequent infection during childhood. Complications may be present in up to 4 of 100 children including serious neurological complications, particularly in developing countries. We report the case of a 9-year-old girl with no disease history who presented with otitis media, otorrhea, intracranial hypertension syndrome, and paralysis of the VI cranial nerve contralateral to the lesion. A computed tomography scan of the skull and a brain magnetic resonance imaging revealed chronic otomastoiditis, petrous apicitis, and thrombosis of the transverse and sigmoid sinus, the jugular bulb, and the right internal jugular vein. She received antibiotics and surgical treatment. This case shows the spectrum of intra and extracranial complications associated with acute otitis media in the antibiotic era. The physical examination allows early identification of intracranial hypertension with signs such as papilledema and sixth contralateral nerve palsy as an unusual finding.

ABSTRACT

Abstract Introduction The prevalence of middle ear disease and its risk factors have been the subject of multiple studies. High prevalence of middle ear disease has been described among North American natives, especially chronic otitis media. Such studies have not been carried out in South America. Objective To describe the prevalence of middle ear pathology and risk factors in native schoolchildren from southern Chile who belong to the Mapuche ethnic group, as well as the impact of socio-economic and demographic changes after 14 years of development. Material and methods Two otologic evaluations with an interval of 14 years were performed in schoolchildren with a percentage of indigenous population above 85%. Socioeconomic and demographic data were collected from national official statistical data. Results A total of 1067 schoolchildren were examined. Many described risk factors for ear pathology were found. An overall prevalence of 0.19% for tympanic membrane perforation, 5.6% for pars tensa retraction pockets, 1.5% for pars flaccida retraction pockets and 11.1% of otitis media with effusion was found. There were several socioeconomic improvements after 14 years. The difference between the prevalence of symptoms and the presence of otitis media with effusion was statistically significant (p < 0.001). Conclusions Despite the presence of several risk factors for middle ear disease, this study population showed a low prevalence of middle ear disease. The ethnic-racial factor seems to be a protective factor.


Resumo Introdução A prevalência de doenças da orelha média e seus fatores de risco já foram objeto de múltiplos estudos. A alta prevalência dessas doenças foi descrita entre os nativos da América do Norte, principalmente a otite média crônica. Tais estudos não foram feitos na América do Sul. Objetivo Descrever a prevalência de doenças da orelha média e fatores de risco em crianças de idade escolar, nativos do sul do Chile pertencentes à etnia Mapuche, bem como o impacto de mudanças socioeconômicas e demográficas após 14 anos de desenvolvimento. Método Foram feitas duas avaliações otológicas com intervalo de 14 anos em escolares com percentual da população indígena acima de 85%. Dados socioeconômicos e demográficos foram coletados a partir de dados estatísticos oficiais nacionais. Resultados Foram examinados 1.067 escolares. Foram encontrados diversos fatores de risco descritos para doença otológica. Foi encontrada uma prevalência geral de 0,19% para perfuração da membrana timpânica, 5,6% para retrações da pars tensa, 1,5% para retração da pars flácida e 11,1% de otite média com efusão. Houve várias melhorias socioeconômicas após 14 anos. A diferença entre a prevalência de sintomas e a presença de otite média com efusão foi estatisticamente significante (p < 0,001). Conclusões Apesar da presença de vários fatores de risco para doença da orelha média, a população estudada apresentou baixa prevalência da doença. O fator étnico parece ser protetor.

ABSTRACT

Introduction : La tympanoplastie en technique underlay vise à mettre un greffon en dessous des reli quats tympaniques. Le but de l'étude était d'en évaluer les résultats anatomiques et fonctionnels au Bénin. Méthode : il s'est agi d'une étude rétrospective réalisée dans le service d'ORL-CCF de l'Hôpital d'Instruction des Armées de Cotonou de novembre 2016 à octobre 2018. Ont été inclus tous les patients ayant bénéficié d'une tympanoplastie en technique underlay pour une otite moyenne chronique simple à tympan ouvert. Les données anatomiques et fonctionnelles pré et post-opératoires ont été comparées à trois mois post-opératoire. Résultat : En deux ans, 10 patients ont bénéficié d'une tympanoplastie soit une incidence de 5 cas par an. L'âge moyen des patients était de 26 ans avec des extrêmes de 17 et 39 ans et une sex-ratio de 0,66. L'abord chirurgical retro-auriculaire et la technique underlay ont été utilisés pour tous les patients. Aucun patient n'a été opéré des deux oreilles. La fermeture de la perfo ration tympanique a été objectivée chez 8 patients sur 10 avec 2 cas de surinfection post-opératoire. Le gain audiométrique moyen a été de 25 dB. Le rinne audiométrique était supérieur à 20 dB chez tous les patients en pré-opératoire et chez 3 patients en post-opératoire. Conclusion : La tympanoplastie est une chirurgie rare au Bénin. Réalisée par la voie retro-auriculaire et la technique underlay, elle a permis d'obtenir d'excellents résultats en termes de fermeture anatomique du tympan mais aussi un gain auditif significatif. C'est une technique à recommander dans nos contextes au Bénin

ABSTRACT

La otitis media aguda (OMA) es una patología muy común en pediatría y constituye la indicación más frecuente de prescripción de antibióticos en la infancia. Para el diagnóstico se tienen en cuenta hallazgos en la otoscopia, diversos signos clínicos y el tiempo de evolución de los síntomas principales. La decisión de iniciar antibioticoterapia debe determinarse según cada paciente. La espera vigilante como alternativa a la antibioticoterapia inmediata en casos seleccionados reduce el uso de antibióticos sin aumentar el riesgo de daño al paciente y ha demostrado ser una medida costo-efectiva. El fármaco de elección para el tratamiento empírico de la OMA es la amoxicilina, aunque según nuestros resultados es la amoxicilina-IBL la utilizada como primera línea en ambos servicios.


Acute otitis media (AOM) is a pathology commonly found in pediatrics, and the most frequent cause of antibiotics prescription in infants. For its diagnostics, several criteria are taken in consideration, such as otoscopy observations, diverse clinical signs, and the time of evolution of the main symptoms. The decision to initiate antibiotic therapy must be determined particularly for each patient. As an alternative to immediate antibiotic therapy, watchful waiting is preferred in certain cases to reduce the antibiotic use without elevating the patients' risk and has been proven to be a cost-effective approach. The preferred drug for empiric antibiotic therapy in AOM is amoxicillin, although we have observed that the first choice in both our services, pediatrics and otorhinolaryngology, is amoxicillin-IBL.

ABSTRACT

Objective: To study the characteristics of wideband tympanometry(WBT) and its application value in the diagnosis of otitis media with effusion(OME) in young children. Methods: We compared wideband acoustic energy absorbance(EA) under peak pressure in young children with OME(190 ears) and healthy control subjects(121 ears) from Ninth People's Hospital of Shanghai Jiaotong University School of Medicine between January 2018 and June 2020. Both groups were divided into three groups, 1-6 months, 7-36 months and 37-72 months. SPSS 20.0 statistical software was used to analyze and compare the EA parameters between OME children of different months and the control group. Receiver operating characteristic (ROC)curve was used to analyze the diagnostic value of WBT in young children with OME. Results: There were significant differences in EA among three OME groups from 500 Hz to 2 000 Hz(P<0.05).Compared with the control groups, EA of 1-6 m OME group decreased significantly below 4 000 Hz(P<0.05), EA of 7-36 m OME group decreased significantly at 545-1 600 Hz(P<0.05), EA of 37-72 m OME group decreased significantly above 545 Hz(P<0.05).ROC curve indicated that EA at 1 000 Hz had the greatest diagnostic value (AUC was 0.890), followed by 1 500 Hz and the range of 500-2 000 Hz (AUC was 0.883 and 0.881, respectively).EA at 1 000 Hz with a cutoff value of 0.55 had the best diagnostic sensitivity of 90.8%, which was higher than conventional tympanometry (85.8%). The maximum AUC (0.932) could be obtained by combining EA, peak pressure and admittance amplitude of 226 Hz tympanometry as predictors. Conclusions: EA is significantly decreased in young children with OME. Compared with the conventional single frequency tympanometry, WBT is more accurate in the diagnosis of OME in young children, and the prediction accuracy would be better if combined with 226 Hz tympanometry.

ABSTRACT

Otitis media is one of the common ear diseases, and its accurate diagnosis can prevent the deterioration of conductive hearing loss and avoid the overuse of antibiotics. At present, the diagnosis of otitis media mainly relies on the doctor's visual inspection based on the images fed back by the otoscope equipment. Due to the quality of otoscope equipment pictures and the doctor's diagnosis experience, this subjective examination has a relatively high rate of misdiagnosis. In response to this problem, this paper proposes the use of faster region convolutional neural networks to analyze clinically collected digital otoscope pictures. First, through image data enhancement and preprocessing, the number of samples in the clinical otoscope dataset was expanded. Then, according to the characteristics of the otoscope picture, the convolutional neural network was selected for feature extraction, and the feature pyramid network was added for multi-scale feature extraction to enhance the detection ability. Finally, a faster region convolutional neural network with anchor size optimization and hyperparameter adjustment was used for identification, and the effectiveness of the method was tested through a randomly selected test set. The results showed that the overall recognition accuracy of otoscope pictures in the test samples reached 91.43%. The above studies show that the proposed method effectively improves the accuracy of otoscope picture classification, and is expected to assist clinical diagnosis.

ABSTRACT

Abstract Introduction: Acute otitis media is a disease with high global prevalence, that can lead to several acute complications and auditory sequelae. Data regarding the auditory evaluation in the acute phase of acute otitis media are scarce. Objective: To evaluate the main audiometric changes (air and bone conduction thresholds) in the initial phase of an acute otitis media episode. Methods: A case-control study was performed. Patients diagnosed with acute otitis media with less than 7 days of evolution in relation to the complaint onset were selected, and healthy volunteers were selected as controls. The acute otitis media and control groups were submitted to pure tone and vocal audiometry. Results: The acute otitis media group included a total of 27 patients (30 ears). Hearing loss was present in 90.0% of the ears with acute otitis media, with conductive loss in 14 (46.67%) and mixed loss in 13 (43.33%). Both the air and bone conduction thresholds obtained with the tonal audiometry in the acute otitis media group were significantly worse than the controls at all tested frequencies (p< 0.05). In patients with acute otitis media, we observed that the thresholds for frequency >1 kHz (bone conduction) and 3 kHz (air conduction) were significantly worse in patients with tinnitus compared to patients without tinnitus. Conclusion: During the first 7 days of evolution after the onset of an isolated episode of acute otitis media, we observed significant increases in bone and air thresholds at all frequencies, especially >2 kHz, compared to healthy ears.


Resumo Introdução: A otite média aguda é uma doença de elevada incidência global, que pode levar a diversas complicações agudas e sequelas auditivas. Dados referentes à avaliação auditiva na fase aguda da otite média aguda são escassos. Objetivo: Avaliar as principais alterações audiométricas (limiares em via aérea e óssea) na fase inicial de um episódio de otite média aguda. Método: Realizou-se estudo de caso-controle. Selecionamos pacientes com diagnóstico de otite média aguda, com menos de sete dias de evolução em relação ao início das queixas, e voluntários saudáveis foram selecionados como controles. Os grupos otite média aguda e controle foram submetidos a audiometria tonal, vocal e audiometria. Resultados: O grupo otite média aguda incluiu 27 pacientes (30 orelhas). Observou-se presença de perda auditiva em 90% das orelhas com otite média aguda, condutiva em 14 (46,67%) e mista em 13 (43,33%). Tanto os limiares auditivos por via aérea quanto os limiares por via óssea obtidos com audiometria tonal do grupo otite média aguda eram significativamente piores em relação aos controles, em todas as frequências testadas (p < 0,05). Em pacientes com otite média aguda, observamos que os limiares das frequências acima de 1 kHz (via óssea) e 3 kHz (via aérea) eram significantemente piores entre pacientes com zumbido em comparação a pacientes sem zumbido. Conclusão: Nos primeiros sete dias de evolução do quadro inicial de um episódio isolado de otite média aguda, observamos aumentos significativos dos limiares ósseos e aéreos em todas as frequências, principalmente nas acima de 2 kHz, em comparação a orelhas sadias.

ABSTRACT

Abstract Introduction: Evidences of possible effects of early age otitis media with effusion in the central auditory processing, emphasize the need to consider such effects also in subjects with chronic otitis media. Aim: To investigate and analyze the impact of non-cholesteatomatous chronic otitis media on central auditory processing in teenagers. Methods: This is a study in which 68 teenagers were recruited, 34 with a diagnosis of non-cholesteatomatous chronic otitis media (study group) and 34 without otological disease history (control group). The evaluation of the subjects consisted of: anamnesis, pure-tone threshold audiometry, speech audiometry and a behavioral test battery for assessment of central auditory processing. Results: A statistically significant difference was found between the means observed in the study and control groups in all tests performed. An association was found between the control group and subgroups of the study group with unilateral alterations in all tests. An association was shown between the results for the control group and study group for family income, with a greater impact on subjects with a lower income. Conclusions: Non-cholesteatomatous chronic otitis media affects the central auditory processing in teenagers suffering from the disorder, and monaural low-redundancy hearing is the most affected auditory mechanism. Unilateral conductive changes cause more damage than bilateral ones, and lower family income seems to lead to more changes to the central auditory processing of subjects with non-cholesteatomatous chronic otitis media.


Resumo Introdução: As evidências de prováveis efeitos de otite média com efusão precoce no proces-samento auditivo central, ressaltam a necessidade de se considerar tais efeitos também em sujeitos com otite média crônica. Objetivo: Investigar e analisar o impacto da otite média crônica não colesteatomatosa no processamento auditivo central em adolescentes. Método: Estudo para o qual foram recrutados 68 adolescentes, 34 com diagnóstico de otite média crônica não colesteatomatosa (grupo de estudo) e 34 sem história otológica (grupo controle). A avaliação dos indivíduos consistiu de: anamnese, audiometria do limiar auditivo para tons puros, audiometria vocal e bateria de testes comportamentais para avaliação do processamento auditivo central. Resultados: Foi encontrada uma diferença estatisticamente significante entre as médias observadas nos grupos de estudo e controle em todos os testes. Foi encontrada uma associação entre o grupo controle e os subgrupos do grupo de estudo com alterações unilaterais em todos os testes. Houve associação entre os resultados dos grupos controle e de estudo para a renda familiar, com maior impacto nos indivíduos com menor renda. Conclusões: A otite média crônica não colesteatomatosa afeta o processamento auditivo central em adolescentes, a audição monoaural de baixa redundância é o mecanismo auditivo mais afetado. Alterações condutivas unilaterais causam mais danos do que as bilaterais e a menor renda familiar parece conduzir a mais alterações no processamento auditivo central de indivíduos com otite média crônica não colesteatomatosa.
