"Step-up"surgical treatment strategy for patulous Eustachian tube / 临床耳鼻咽喉头颈外科杂志

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.

Clinical analysis of 11 cases of otogenic intracranial complications treated by multidisciplinary collaboration / 临床耳鼻咽喉头颈外科杂志

Objective:To analyze the clinical diagnosis, treatment ，and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University（Qingdao） from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.

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.

Quiste epidermoide en conducto auditivo externo: reporte de caso / Epidermoid cysts of the external auditory canal: case report

Resumen El quiste epidérmico es una lesión benigna y común de la piel. Se desarrolla por un bloqueo de la unidad pilosebácea, con la consecuente proliferación de células epiteliales y secuestro de queratina. El 7% se desarrollan en cabeza y cuello, sin embargo, son infrecuentes en canal auditivo externo. Su patrón de crecimiento es lento y progresivo durante años, siendo asintomáticos. Al aumentar de tamaño causan sintomatología variable, acorde a su localización; en el canal auditivo tienen un comportamiento obstructivo que genera síntomas como otalgia e hipoacusia. Se presenta caso de una paciente de 69 años, con acúfeno e hipoacusia progresiva derecha. Durante la otoscopia se observó una neoformación obstructiva del 100% de la luz del conducto. Se realizaron estudios de imagen que reportaron tumoración de características quísticas de conducto auditivo derecho, bien circunscrita, sin erosión ósea. Para el diagnóstico definitivo, se realizó resección quirúrgica y biopsia reportando quiste epidérmico. Durante el seguimiento posoperatorio sin hallazgos de recidiva.

Abstract The epidermal cyst is a common and benign lesion of the skin. It develops due to a blockage of the pilosebaceous unit, with the consequent proliferation of epithelial cells and keratin sequestration. Seven percent develop in the head and neck; however, they are infrequent in the external auditory canal. Its growth pattern is slow and progressive over the years, being asymptomatic. As they increase in size, they cause variable symptoms, according to their location. In the ear canal they have an obstructive behavior that generates symptoms such as earache and hearing loss. A case of a 69-year-old female with tinnitus and progressive right hearing loss is presented. At otoscopy, a 100% obstructive neoformation of the canal lumen was observed. Imaging studies showed a well circumscribed, cystic tumor of the right ear canal, without bone erosion. For the definitive diagnosis, a resection and biopsy were performed, reporting an epidermal cyst. During follow up there was no recurrence of tumor.

Clinical and imaging features of middle ear hairy polyps / 中华耳鼻咽喉头颈外科杂志

Objective: To collect the clinical cases of middle ear hairy polyp, and to summarize the imaging features. Methods: We retrospectively analyzed the clinical data of four cases middle ear hairy polyp confirmed by surgical and pathologic between January 2007 and January 2020 at the Affiliated Eye & ENT Hospital of Fudan University. There were three females, one male, with two left ears and two right ears, aged from 1 to 59 years. The CT and MRI imaging of the patients, and the corresponding clinical manifestations were analyzed. Results: Hairy polyps originated from tympanum in one case, originated from Eustachian tube in two cases, exhibiting recurrent otorrhea without evident inducement. The other case, hairy polyps originated from the Eustachian tube pharyngeal orifice and protruded into the nasopharyngeal cavity, with pharynx discomfort and aural fullness, endoscope showed offwhite polypoid mass with a little hair. All the four cases presented polypoid soft tissue masses on CT and MRI imaging, containing soft tissue wall and a large amount of adipose tissue, with soft tissue in the center of the mass which liked the core, and enhanced. MRI showed stratified arrangement of fat and soft tissue in the wall of the mass. Four cases all had surgical treatment, postoperative pathology examination presented that hair follicles, mature sebaceous glands and other skin appendages were found under squamous epithelium. A large amount of adipose tissue, part of muscle tissue, cartilage tissue, and some fibro-collagenous tissue were proliferated in the mass, accompanied by collagen degeneration. Conclusion: The middle ear hairy polyps has imaging characteristics, the polypoid soft tissue mass usually looks smooth and contains a large amount of adipose tissue, with a soft tissue in the center, and can be suggestively diagnosed by CT and MRI.

Prevalence of Mild Hearing Loss in Schoolchildren and its Association with their School Performance

Abstract Introduction Hearing is important for the proper development of every child, especially for those younger than 5 years of age, because it helps in the development of language and speech. Emotional and social problems, as well as issues with academic performance, can result from hearing loss even of mild degree. Early diagnosis and management can overcome those negative impacts. Objective To determine the prevalence of mild hearing loss in primary-school children and its association with their school performance. Methods A comparative cross-sectional study was conducted at a regular school. The study included the random selection of 120 apparently normal students (aged 6-9 years) who were considered as having normal hearing by their parents. A total of 20 students were excluded from the study due to the presence of wax in their ears. Finally, the study was conducted with 100 students. All participants were subjected to a basic audiological evaluation, and the Screening Instrument for Targeting Educational Risk (SIFTER) question- naire was given to their teachers to evaluate their school performance. Results From a total of 100 students, we confirmed that 23 (23%) had mild hearing loss, 17 (17%) had bilateral conductive hearing loss, and 6 (6%) had bilateral sensorineural hearing loss. The students who had low attention and communication performance were significantly associated with mild hearing loss. Conclusion The prevalence of mild hearing loss was of 23% (23 cases). This problem had an effect on the communication and attention in school; and it might affect academic performance later in life. A hearing assessment is highly recommended for every child, especially those who have a low rate of academic performance.

Disfunción del conducto faringotimpánico. El ETDQ-7 como herramienta para el diagnóstico clínico / Pharyngothympanic tube dysfunction. The ETDQ-7 as a tool for clinical diagnosis

RESUMEN En la actualidad se hace referencia en la bibliografía a una gran variedad de métodos para evaluar la disfunción del conducto faringotimpánico (DCFT), la gran mayoría de ellos requiere de instrumental de alta complejidad y personal altamente capacitado. Pese a lo mencionado, ninguno de dichos métodos ha sido validado como herramienta gold standard para el diagnóstico de esta patología. En este contexto, se presenta una herramienta complementaria para el diagnóstico de la DCFT, el Eustachian Tube Dysfunction Questionnaire -7 ítemes (ETDQ-7); cuestionario autoadministrado que considera 7 preguntas en base a una escala de Likert, fue creado para evaluar la sintomatología asociada a la disfunción del conducto con una puntuación que va desde lo más leve (1 punto) a lo más grave (7 puntos) de acuerdo con los síntomas percibidos, y posee un puntaje máximo de 49 puntos, correspondiente a una disfunción severa. La presente revisión tiene como objetivo buscar, organizar, clasificar y describir la información disponible en publicaciones científicas indexadas sobre el ETDQ-7 como herramienta para el diagnóstico clínico complementario de la DCFT. Se incluyeron 11 artículos científicos que hacen referencia al uso del ETDQ-7 en diferentes países. Los resultados recabados sugieren que el ETDQ-7 sería una valiosa herramienta, de alta sensibilidad, especificidad y validez clínica, que permitiría discriminar la presencia de la DCFT. No se encontró evidencia respecto a la aplicación o validación de este cuestionario en nuestro país.

ABSTRACT At present, great variety of methods are described to evaluate the dysfunction of the pharyngotympanic duct (DCFT), the vast majority of them require highly complex instruments and highly trained personnel. Despite this, none of these methods has been validated as the gold standard for the diagnosis of this pathology. In this context, a complementary tool for the diagnosis of the DCFT is presented. The Eustachian Tube Dysfunction Questionnaire-7 items (ETDQ-7), a self-administered questionnaire that includes 7 questions based on a Likert scale, was created to evaluate the symptomatology associated with the dysfunction of the duet. It is scored ranging from the mildest symptomatology (1 point) to the most severe (7 points), according to the perceived symptoms, with a maximum score of 49 points, corresponding to a severe dysfunction. The present review aims to search, organize, classify and describe the available information in scientific indexed journals about the ETDQ-7 as a tool for complementary diagnosis of the DCFT. Eleven scientific articles were included, referred to the use of ETDQ-7 in different countries, describing it as a valid tool which allows to discriminate the presence of a DCFT.

Consideraciones perioperatorias para cirugía otológica en época de COVID-19 / Perioperative aspects in otologic surgery during COVID-19 era

La cirugía electiva en otología se ha visto afectada por la pandemia del COVID-19. No sabemos cuánto tiempo pasará hasta que veamos un descenso en el número de casos nuevos y podamos volver al ejercicio médico que conocíamos. Mientras tanto, debemos adaptarnos rápidamente a la nueva forma de funcionamiento de los servicios quirúrgicos en otología, siguiendo los protocolos que están surgiendo para la reactivación gradual y segura de esta clase de actividad. El objetivo de este artículo es realizar una revisión narrativa de la literatura sobre las nuevas recomendaciones para la reactivación de los servicios quirúrgicos otológicos durante esta pandemia, estableciendo pautas seguras en el manejo perioperatorio. Una de las metas más importantes es brindar una guía sobre la forma de comportarse dentro del ambiente de los quirófanos, sus cambios operacionales, el correcto uso de elementos de protección personal y dar a conocer métodos que busquen disminuir la exposición del equipo quirúrgico a la aerosolización, describiendo una técnica novedosa de vestido del microscopio de doble cubrimiento con extensión cefálica para el cirujano.

Otologic surgical procedures have been affected by the COVID-19 pandemic. Is not known how long it will be until we see a decrease in the number of new cases and when we will be able to return to our usual medical practice. Meanwhile, we must adapt quickly to a new surgical practice in the COVID era. This article discuses recommendations for reactivating otological surgical services during the pandemic, establishing safe guidelines for ear surgery and for postoperative patient follow-up. One of the most important goals is to provide recommendations on how to behave in the operating room, how to use personal protection elements and to present new methods that seek to reduce the exposure of the surgical team to aerosolization. Here we describe a novel technique using the already described double draping technique and adding an extension for the surgeon´s protection.

Translation, validation and cultural adaptation of "The Eustachian Tube Dysfunction Questionnaire-7" (ETDQ-7) to Brazilian Portuguese (BR) / Tradução, validação e adaptação cultural do questionário "The Eustachian Tube Dysfunction Questionnaire-7" (ETDQ-7) para o português brasileiro (BR)

Abstract Introduction: Chronic Eustachian tube dysfunction can cause several symptoms and middle ear conditions that can impact patient quality of life. It is estimated to be relatively frequent, affecting approximately 5% of adults. The diagnostic tools for this condition are still inadequate. In 2012, McCoul et al. published a questionnaire for the evaluation of Eustachian tube dysfunction named ETDQ-7. They established its replicability and validity. The cutoff point for the diagnosis of chronic Eustachian tube dysfunction was equal to or greater than 14.5, with 100% sensitivity and 100% specificity. Objective: To translate, adapt and validate the ETDQ-7 questionnaire to Brazilian Portuguese. Methods: We translated the questionnaire into Brazilian Portuguese and applied it to 50 patients, 20 of whom had chronic Eustachian tube dysfunction, and 30 controls. Results: The results obtained with the North-American questionnaire were confirmed in its Brazilian version. The cut-off point for the diagnosis of chronic Eustachian tube dysfunction was ≥14, also exhibiting high sensitivity and specificity, very similar to that of ETDQ-7. Conclusion: It is recommended that ETDQ-7 be used to complement the clinical history of patients with chronic Eustachian tube dysfunction; it can also be used as an important tool for diagnosis, patient follow-up and treatment management.

Resumo Introdução: A disfunção crônica da tuba auditiva pode causar diversos sintomas e doenças de orelha média e impactar a qualidade de vida dos pacientes. Estima-se que é uma morbidade relativamente frequente, acomete cerca de 5% dos adultos. Os instrumentos diagnósticos para essa afecção ainda são insuficientes. Em 2012 McCoul et al. publicaram um questionário para a avaliação da disfunção da tuba auditiva denominado ETDQ-7. Eles demonstraram sua reprodutibilidade e validade. O ponto de corte para o diagnóstico de disfunção de disfunção crônica da tuba auditiva foi de maior ou igual a 14,5 com 100% de sensibilidade e 100% de especificidade. Objetivo: Traduzir, adaptar e validar o questionário ETDQ-7 para o português brasileiro. Método: Traduzimos o questionário para o português do Brasil e o aplicamos em 50 pacientes, 20 com disfunção crônica da tuba auditiva e 30 controles. Resultados: Os resultados obtidos no questionário americano foram confirmados na versão brasileira. O ponto de corte para o diagnóstico de disfunção crônica da tuba auditiva foi maior ou igual a 14, também com alta sensibilidade e especificidade, muito semelhante ao ETDQ-7. Conclusão: Recomenda-se que o ETDQ-7 seja usado como um complemento na história clínica do paciente com disfunção crônica da tuba auditiva e pode ser usado também como uma importante ferramenta para fins de diagnóstico, seguimento de pacientes e manejos no tratamento.

Wideband acoustic absorbance in children with Down syndrome / Absorvância acústica de banda larga em crianças com síndrome de Down

Abstract Introduction: Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226 Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients. Objective: The aim of this study was to analyze the acoustic absorbance measurements in children with Down syndrome. Methods: Cross-sectional study, approved by the institution's ethics committee. Data were collected from 30 children, with a mean age of 8.4 years, 15 with Down syndrome (DS-study group) and 15 children with typical development and no hearing complaints (control group). Energy absorbance was measured at frequencies of 226-8000 Hz at ambient pressure and at peak pressure as a function of frequency using TITAN equipment. Statistical analysis was performed using the established level of statistical significance of 5%. Results: With the 226 Hz probe tone, 30 ears of the control group and 22 of the study group exhibited Type A tympanograms, whereas Type B was observed in eight children in the study group. The mean acoustic absorbance ratio of the study group was lower than that of the control group at frequencies centered at 2520 Hz (p = 0.008) for those with normal tympanometry results, and 226-4000 Hz (p < 0.03) for those with a Type B tympanometry curve. Conclusion: The low energy absorption in the presence of normal tympanograms in children with Down syndrome may suggest middle ear abnormalities.

Resumo Introdução: A timpanometria é a ferramenta mais usada para avaliar o status da orelha média, comumente avaliada por meio de uma única frequência com o tom de 226 Hz. No entanto, o uso da medida de imitância acústica com estímulo de banda larga é uma avaliação de alta resolução promissora, especialmente em pacientes conhecidos por frequentemente apresentar alterações da orelha média, como na síndrome de Down. Objetivo: Analisar as medidas de absorvância acústica em crianças com síndrome de Down. Método: Estudo transversal, aprovado pelo comitê de ética da instituição. Foram coletados dados de 30 crianças, com idade média de 8,4 anos, sendo 15 com síndrome de Down (SD-grupo de estudo) e 15 crianças desenvolvimento típico e sem queixas auditivas (grupo controle). A absorvância de energia foi medida nas frequências de 226-8.000 Hz à pressão ambiente e no pico de pressão em função da frequência, usou-se o equipamento Titan. A análise estatística foi feita com o nível de significância estatística adotado de 5%. Resultados: Com o tom de sonda de 226 Hz foram observadas 30 orelhas do grupo controle e 22 do grupo estudo com timpanometria Tipo A e o Tipo B foi observado apenas em oito crianças do grupo estudo. A razão média de absorvância acústica do grupo estudo foi menor do que a do controle nas frequências centradas em 2.520 Hz (p = 0,008) para aqueles com resultados timpanométricos normais e de 226-4.000 Hz (p < 0,03) para aqueles com curva timpanométrica Tipo B. Conclusão: A baixa absorção de energia na presença de timpanogramas normais nas crianças com síndrome de Down pode sugerir anormalidades na orelha média.

Perception of the Quality of Life of Tobacco Growers Exposed to Pesticides: Emphasis on Health, Hearing, and Working Conditions

Abstract Introduction Tobacco farming exposes workers to various health risks due to the high application of pesticides needed to control pests, weeds and fungal diseases that prevent the tobacco plant growth. Objective To analyze the perception of the quality of life of tobacco growers exposed to pesticides, with emphasis on general health, hearing, and working conditions. Method This is a descriptive, cross-sectional study using a quantitative approach with farmers from southern Brazil. Data were collected from November of 2012 to November of 2014. For data collection, we opted for the 36-item short form health survey (SF-36) questionnaire, and a questionnaire with closed questions about health, hearing and working conditions. We evaluated a total of 78 subjects; the study group, made up of 40 tobacco farmers exposed to pesticides, and a control group of 38 participants without occupational exposure to pesticides. Both groups are residents of the same municipality, and users of the federal public health system. Results The results showed that tobacco growers had lower quality of life scores compared with the control group. Significant differences were observed in the areas of pain and general health. There were correlations between physical elements and chronic diseases; hearing complaints and a lack of personal protective equipment use, occupation and hearing complaints, as well as general health and hearing complaints. Conclusion Tobacco farming is a risky activity for general and hearing health, and it can impact the quality of life of those working in this field. (AU)

Otomyiasis: Systematic Review

Abstract Introduction Myiasis is a disease causedby fly larvae that growinthetissues of animals and humans. It can cause a variety of local symptoms, like erythema or pain, depending on its location, and generalized symptomatology, such as fever andmalaise.Myiasis can generate severe complications, for instance sepsis, or directly impact vital tissues. Its management varies depending on the location, and on the preferences of the doctor that faces this challenge. Myiasis usually occurs in tropical countries, and, in many places, it is not a rare condition. The cases are rarely reported, and there are no publishedmanagement protocols. Objective To review the literature regarding the most common agents, the predisposing factors and the treatment alternatives for otic myiasis, a rare form of human myiasis caused by the infestation of fly larvae in the ear cavities. Data synthesis We present a systematic review of the literature. The search in five databases (Medline, Embase, Cochrane Database of Systematic Reviews, LILACS and RedALyC) led to 63 published cases from 24 countries, in the 5 continents. The ages of the patients ranged fromnewborn to 65 years old. Themost common agents belong to the Sarcophagidae or Calliphoridae families. Chronic otitis media, previous otic surgical procedures, mental deficit, alcohol or drug abuse, sleeping outdoors, prostration, and malnutrition were predisposing factors. The treatment alternatives are herein discussed. Conclusion The results highlight the need for monitoring, follow-up and standardization of medical approaches. (AU)

Otologic Findings Based on no Complaints in a Pediatric Examination

Abstract Introduction the otological evaluation is highly significant in those branches of medicine in which the general evaluation of the patient is conducted by general practitioners and pediatricians. Objectives To investigate the otologic findings and their incidences in the sample, which consisted of patients who presented to the pediatric outpatient clinic with nonotologic complaints. Methods Patients, aged between 2 and 16 years, who had neither otorhinolaryngological complaints nor history of surgery by the otolaryngology (ear, nose and throat, ENT) department were included in the present study. The findings detected in the external auditory system and in the tympanic membranes as well as the otorhinolaryngologists' otologic examination findings of the referred patients were recorded from the files of each patient along with the applied medical and surgical treatments, and diagnostic investigations. Results Of a total of 973 patients evaluated, 129 (13.2%) were referred to the ENT outpatient clinic due to any otologic pathology. In the otorhinolaryngological examinations, false positivity was detected in 12 (1.2%) patients, and pathological findings were detected in 117 (12%) patients who received the following diagnoses: 68 (6.9%) had otitis media with effusion(OME); 37 (3.8%) had cerumen impactions; 8 (0.8%) had acute otitismedia (AOM); 2 (0.2%) had ticks in the external auditory canal; 2 (0.2%) had a retraction pocket in tympanic membrane; 1 (0.1%) had unilateral central dry perforation of the tympanic membrane; and 1(0.1%) had congenital cholesteatoma. Conclusion Any complications and sequelae that may develop due to any pathologies and predominantly infections can be prevented by an early diagnosis, which can be made by means of a simple examination, performed merely with an otoscope. Pediatricians and general practitioners should be in close contact with otorhinolaryngologists regarding the pathologies they identify. (AU)

Temporomandibular disorder: otologic implications and its relationship to sleep bruxism / Disfunção temporomandibular: implicações otológicas e sua relação com o bruxismo do sono

Abstract Introduction: Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder. That condition can result in pain otologic symptoms. Objective: The aim of the present study was to investigate the relationship between temporomandibular disorder and both otologic symptoms and bruxism. Methods: A total of 776 individuals aged 15 years or older from urban areas in the city of Recife (Brazil) registered at Family Health Units were examined. The diagnosis of temporomandibular disorder was determined using Axis I of the Research Diagnostic Criteria for temporomandibular disorders, addressing questions concerning myofascial pain and joint problems (disk displacement, arthralgia, osteoarthritis and osteoarthrosis). Four examiners had previously undergone training and calibration exercises for the administration of the instrument. Intra-examiner and inter-examiner agreement was determined using the Kappa statistic. Individuals with a diagnosis of at least one of these conditions were classified as having temporomandibular disorder. The diagnosis of otologic symptoms and bruxism was defined using the same instrument and a clinical exam. Results: Among the individuals with temporomandibular disorder, 58.2% had at least one otologic symptom and 52% exhibited bruxism. Statistically significant associations were found between the disorder and both otologic symptoms and bruxism (p < 0.01 for both conditions; OR = 2.12 and 2.3 respectively). Otologic symptoms and bruxism maintained statistical significance in the binary logistic regression analysis, which demonstrated a 1.7 fold and twofold greater chance of such individuals have temporomandibular disorder, respectively. Conclusion: The logistic regression analysis demonstrated strong associations between the disorder and both otologic symptoms and bruxism when analyzed simultaneously, independently of patient age and gender.

Resumo Introdução: A disfunção temporomandibular é um termo que engloba vários problemas clínicos que afetam os músculos da mastigação, a articulação temporomandibular e estruturas associadas. Esse distúrbio tem uma etiologia multifatorial, com hábitos parafuncionais orais considerados um importante cofator. Entre esses hábitos, o bruxismo do sono é considerado um agente causador envolvido no desenvolvimento e/ou na perpetuação de disfunção temporomandibular. Esse problema pode resultar em sintomas otológicos dolorosos. Objetivo: Investigar a relação entre disfunção temporomandibular e os sintomas otológicos e bruxismo. Método: Foram examinados 776 indivíduos com idade igual ou superior a 15 anos de áreas urbanas da cidade de Recife (Brasil) registrados nas Unidades de Saúde da Família. O diagnóstico da disfunção foi determinado utilizando o Eixo I dos Critérios de Diagnóstico de Pesquisa para Distúrbios Temporomandibulares, abordando questões relativas a dor miofascial e problemas articulares (luxação discal, artralgia, osteoartrite e osteoartrose). Quatro examinadores foram treinados para a administração do instrumento. A concordância intraexaminador e interexaminador foi determinada usando a estatística Kappa. Os indivíduos com diagnóstico de pelo menos uma dessas condições foram classificados como tendo disfunção temporomandibular. O diagnóstico de sintomas otológicos e bruxismo foi definido utilizando o mesmo instrumento de diagnóstico e exame clínico. Resultados: Entre os indivíduos com a disfunção, 58,2% apresentaram pelo menos um sintoma otológico e 52% apresentaram bruxismo. Foram encontradas associações estatisticamente significativas entre a disfunção temporomandibular e ambos os sintomas otológicos e bruxismo (p < 0,01 para ambos os problemas, OR = 2,12 e 2,3, respectivamente). Os sintomas otológicos e o bruxismo mantiveram significância estatística na análise de regressão logística binária, o que demonstrou uma probabilidade de 1,7 e 2 vezes maior chance de que esses indivíduos tenham disfunção temporomandibular, respectivamente. Conclusão: A análise de regressão logística demonstrou associações fortes entre disfunção temporomandibular e sintomas otológicos e bruxismo quando analisados simultaneamente, independentemente da idade e do sexo do paciente.

Turkish validity and reliability of Eustachian tube dysfunction questionnaire-7 / Validade e confiabilidade do Eustachian tube dysfunction questionnaire-7 no idioma turco

Abstract Introduction During clinical evaluations, in order to interpret patients' complaints caused by Eustachian tube dysfunction and to monitor the success of the treatment, standardized and disease-related scales are necessary. Objective The aim of this study was to investigate the validity and reliability of the Turkish version of Eustachian tube dysfunction questionnaire-7. Methods Forty patients diagnosed with Eustachian tube dysfunction and 40 healthy individuals were enrolled for the study. After language validation of the Eustachian tube dysfunction questionnaire-7 for Turkish, a scale was completed by the both Eustachian tube dysfunction and control groups. Two weeks after the first evaluation, 15 of the cases filled out the scale again without any treatment intervention. Known-groups method was used in validity analysis. Floor-ceiling effect, test-retest method, item-total score correlation and internal consistency analysis were used in reliability analyses. Results Cronbach's alpha coefficient was 0.714 for the entire questionnaire. The test-retest reliability coefficient for the total scale was determined as 0.792, indicating correlation between the two questionnaires completed by the same patient over time. In the Eustachian tube dysfunction group, total and each item scores were found significantly higher than the control group (p < 0.001). Conclusion The Turkish version of Eustachian tube dysfunction questionnaire-7 was found to be highly valid and reliable. This scale is recommended to use for screening of Eustachian tube dysfunction and evaluating treatment outcome.

Resumo Introdução No intuito de interpretar as queixas dos pacientes causadas por disfunções na tuba auditiva durante uma avaliação clínica, e para monitorar o sucesso do tratamento, há necessidade de escalas padronizadas relacionadas à doença. Objetivo Investigar a validade e a confiabilidade da versão turca do Eustachian tube dysfunction questionnaire-7. Método Quarenta pacientes diagnosticados com disfunção da tuba auditiva e 40 indivíduos saudáveis foram incluídos no estudo. Após a validação do Eustachian tube dysfunction questionnaire-7 para o idioma turco, o questionário foi aplicada aos grupos disfunção da tuba auditiva e controle. Duas semanas após a primeira avaliação, 15 pacientes preencheram o questionário novamente sem qualquer tratamento. O método de grupos conhecidos foi utilizado na análise de validade. Os efeitos teto e chão, o método teste-reteste, a correlação se escore de item-total e a análise de consistência interna foram utilizados nas análises de confiabilidade. Resultados O coeficiente alfa de Cronbach foi de 0,714 para todo o questionário. O coeficiente de confiabilidade teste-reteste para a escala total foi determinado como 0,792, indicando correlação entre os dois questionários preenchidos pelo mesmo paciente ao longo do tempo. No grupo disfunções da tuba auditiva, foi observado que os escores total e de cada item foram significativamente maiores do que no grupo controle (p < 0,001). Conclusão A versão no idioma turco do Eustachian tube dysfunction questionnaire-7 foi considerada altamente válida e confiável. Recomenda-se a utilização dessa escala para a triagem de disfunções da tuba auditiva e avaliação do resultado do tratamento.

Lobomycosis: a therapeutic challenge

Abstract: Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.
